K-type horizontal inquiry machine product details-structural characteristics and technical parameters

What is the K-type horizontal inquiry machine: definition and naming origin

The K-type horizontal inquiry machine is a structural branch of the horizontal inquiry machine. It is named after the side contour of the whole machine is similar to the oblique cut shape of the letter "K"-the operation table is inclined at a fixed angle from the middle section of the machine body to the operator's side, and the screen is embedded in the inclined plane instead of facing the user vertically like a vertical machine. This name is not marketing packaging, but the industry's customary structure of the name, to facilitate the purchaser in the quotation and drawing quickly identify the structure type, and "L-shaped" (the support structure is L-shaped, the table is more gentle) to form a distinction.

It is important to understand this: choosing a K-type or an L-type is essentially choosing an engineering solution of "operating table angle and support structure" rather than choosing an appearance style. This is also the reason why this paper puts structural analysis in the front.

Structural design analysis: inclined touch surface, anti-misoperation mechanism and ergonomics

Angle Design Logic for Beveled Touch Surface

The tilt angle of the table top is not arbitrarily set, but to find a balance between "the natural line of sight depression angle of standing operation" and "the arm can comfortably reach the screen after natural drooping"-if the angle is too small, the user will hunch forward for a long time; If the angle is too large, the screen reflection problem will be more obvious. QUNMAO in the structural design stage will be for different height distribution of the user population to do ergonomic accounting, to ensure that the vast majority of adult users do not need to deliberately adjust the posture to complete the operation.

Anti-touch mechanism

The inclined plane structure itself can reduce the probability of false touch caused by the user's inadvertent use of the palm or clothing against the body, which is a structural advantage over the pure flat surface design; on this basis, the sensitivity optimization of the edge area with the touch algorithm can further reduce the invalid trigger.

Route concealment and structural strength

Independent channels are reserved for cable routing inside the fuselage of Type K. All connecting lines and power lines between the main engine box and the inclined surface table pass through the inside, and there will be no pulling or man-made damage of exposed cables. The whole fuselage has been checked by anti-dumping structure, which is suitable for long-term standing use in public places with dense flow of people and possible bumping. This structural scheme is consistent in the QUNMAO32-85-inch full series of models, and will not sacrifice the cleanliness and structural stability of the wiring due to the larger screen size.

More details of the structural design (including specific engineering parameters of the slope angle, material stress test methods) can be found in Special Article。

Appearance size and material process

The appearance process of the K-type horizontal inquiry machine mainly revolves around three dimensions:

• Sheet metal structure:The main body frame adopts integrated sheet metal forming or split welding process, and the surface is sprayed with plastic or wire drawing to give consideration to both strength and appearance texture;
• Glass Panels:The operating table usually uses tempered glass to cover the screen area, which has the characteristics of anti-scratch, anti-fingerprint, and easy cleaning, and is suitable for hospitals, government affairs and other scenes that require high hygiene and durability;
• surface treatment and color matching:Support spray, paint and other surface treatment process, color can be customized according to customer brand VI, to match the hospital, government hall, bank outlets and other different places of the overall space style.

The overall landing size of the appearance is usually controlled within the comfortable range of conventional adult standing operation, and the specific size will vary depending on the screen size and function module configuration. QUNMAO adopts a unified structure and process standard on the full range of products from 32 inches to 85 inches. Even for 85-inch large screen models, the sheet metal strength and glass panel process are also strengthened to avoid the structural deformation risk caused by large screen.

Core hardware parameters: screen, touch scheme and motherboard system

When choosing a K machine, in addition to looking at the structure, hardware parameters are also key to determining long-term stability. The following is a parameter comparison of the common configuration of the third gear of the K-type horizontal query machine, which is convenient for you to quickly locate according to the actual budget and scene:

Regarding the choice of touch scheme: due to the small and medium size of the table top, the mainstream interval of 21.5 "-27" is mainly capacitive screen, which has high touch precision and supports multi-point operation. After entering the large screen interval of 32 "and above, QUNMAO adopts the infrared touch scheme uniformly-the infrared screen under the large screen has more advantages in cost performance and durability, and also naturally supports glove operation and dust-resistant environment, the adaptation range is wider than the capacitive screen of the same size.

Regarding mainboards and systems: for 7x 24 operation scenarios such as hospitals and government affairs, it is recommended to directly select industrial-grade mainboards to avoid stability problems after long-term operation of consumer-grade mainboards. If compliance requirements are involved, it is necessary to confirm with the manufacturer in advance whether the adaptation of domestic operating systems is supported.

List of full series models and sizes of K-type horizontal inquiry machine

In order to enable the purchaser to directly correspond to the specific model when making inquiries and docking drawings, QUNMAO arranges the full series of models of 32-inch to 85-inch horizontal infrared touch integrated machines as follows:

These 7 models all follow the design of anti-misoperation and routing concealment of K-shaped inclined plane structure. The difference mainly lies in the difference of display information and visual presentation effect brought by screen size. The purchaser can directly select the seven models from QM‑C32XJ to QM‑C85XJ according to the space size, viewing distance and information display density of the point, without the need to develop a non-standard size scheme. If the actual point has special requirements for size, QUNMAO also supports further customization on the basis of this model series.

The core selling point of K-type horizontal inquiry machine

Combined with structural design and hardware configuration, the core value of K-type horizontal query machine in actual use can be summarized as follows:

• Stable anti-touch. The combination scheme optimized by the slope structure touch algorithm can significantly reduce the invalid trigger rate compared with the plane query function, and reduce the system stuck or wrong operation complaints caused by false touch.
• Clean wiring and regular appearance. The internal wiring design keeps the appearance of the equipment table top and body clean and tidy, avoiding potential safety hazards and perception problems caused by cable exposure, which is especially important in places such as hospitals and government halls that require environmental cleanliness.
• Adapt to serious, high-frequency scenes. Structural strength and ergonomic design are the basis for the long-term and stable service of K-machine in high-frequency, 7x 24-hour operation scenarios such as hospital registration payment, government affairs inquiry, bank branch business inquiry, etc.

Overview of applicable scenarios

Typical application scenarios of the K-type horizontal inquiry machine include:

• Hospital: registration, payment, report inquiry-usually used in conjunction with the queuing machine to ease the pressure of queuing at the window;
• Government affairs hall: integrated handling of matters inquiry, material pre-examination, number taking and printing;
• Bank outlets: business inquiries, promotional materials broadcast, simple business appointments;
• Operator's business hall: bill inquiry, package consultation and business handling guidance.

Each scenario has slightly different specific requirements for configuration-for example, hospital scenarios are more adaptable to aging design and easy-to-clean materials, and government scenarios place more emphasis on trust compliance and data docking capabilities. Judging from QUNMAO's project experience, 43-inch QM‑C43XJ or 49-inch QM‑C49XJ can usually meet the information display requirements for scenes such as hospitals and government halls that mainly focus on query functions. If it is a scene such as a bank branch and an operator's business hall that needs to take into account both business inquiry and publicity display, a 55-inch QM‑C55XJ can be considered to obtain a better visual presentation effect. The detailed application scheme of K-type horizontal inquiry machine in hospital scene can be found in Hospital Scene Scheme。

Optional function modules

According to specific business needs, the K-type horizontal inquiry machine can be equipped with the following functional modules:

• Card swiping module: support ID card, social security card, bank card and other reading, to meet the needs of identity verification or member identification;
• Scan code module: supports two-dimensional code/bar code scanning, used for electronic bill verification, mobile payment and other scenarios;
• Printing module: supports thermal receipt printing or A4 document printing to meet the printing requirements of vouchers, reports and bill of materials.

The above modules all support native integration rather than later external modification to ensure the integrity and long-term stability of the whole structure. Whether it is a 32-inch QM-C32XJ or an 85-inch QM-C85XJ,QUNMAO has reserved a unified installation position and routing channel for these functional modules in the structural design stage. Customers can combine them in the same series as needed without worrying about the incompatibility of the modules after changing sizes.
