Description

Technical Field

[0001] This utility model relates to the field of folding support technology in the box body, and in particular to a box structure that facilitates heat dissipation of multiple components. Background Technology

[0002] In examination settings, such as national-level examinations like the National College Entrance Examination (NCEE), Adult Higher Education Entrance Examination (AHEEE), Self-Study Examination, and Postgraduate Entrance Examination, candidates must take the exams in standardized examination rooms, in accordance with the requirements of the Ministry of Education Examination Authority, to facilitate management and ensure the fairness and impartiality of the examinations.

[0003] Standardized examination room construction specifications require the inclusion of equipment such as candidate identity verification, online monitoring, anti-cheating devices, electronic clocks, and broadcasting systems. In traditional standardized examination room construction, various examination devices are fixedly installed in different locations within the examination room (classroom). For example, the electronic clock is installed at the front of the examination room, the online monitoring camera at the front left, and the anti-cheating device at the rear. Traditional standardized examination room construction has the following problems: 1. Each standardized examination room system has independent equipment installed within the examination room, resulting in high construction costs. 2. The equipment is scattered, hindering maintenance and support. 3. The fixed installation of equipment restricts the selection of examination rooms during examination organization.

[0004] Therefore, users desire a portable, mobile, integrated standardized examination room device with the essential functions required for a standardized examination room. During the examination, the device can be simply set up in the examination room to create a standardized examination room that meets the requirements.

[0005] Therefore, our company has developed a portable, mobile, standardized integrated examination room equipment box. It features functions such as candidate identity verification, online monitoring, cheating prevention, an electronic clock, and a broadcasting system. The box-shaped device includes casters and a retractable lever. Inside, a folding support column houses a flat-panel display, a camera, a battery pack, a 4G router, a control panel, an anti-cheating device, and a speaker, integrating all the necessary functions for the examination. When an examination is scheduled for a classroom, the box is simply moved to the designated classroom, and the device unfolds. It enables facial verification, voice broadcasting, display of examination information, and anti-cheating measures. It can operate without power or internet access, making it extremely convenient.

[0006] Based on customer feedback, the first version of the product design had the following defects during use: 1. Due to the long-term operation of the entire enclosure, heat dissipation was poor, affecting the performance of the control circuit board. If the anti-cheating device (shield) was exposed to high temperatures, the shielding effect would be poor; 2. The internal wiring was somewhat redundant. The customer's requirements were: 1. Good heat dissipation of the enclosure to not affect the use and operation performance of the entire device; 2. A simple internal design; 3. Minimize the overall weight of the enclosure.

[0007] This solution mainly focuses on improving heat dissipation and reducing redundancy, as well as providing protection. Summary of the Invention

[0008] The purpose of this utility model is to overcome the shortcomings of the prior art and provide a box structure that facilitates heat dissipation of multiple components, thereby solving the problem of poor heat dissipation in existing examination box equipment. This solution achieves good heat dissipation of each component in the box through a very simplified structure inside the box.

[0009] The purpose of this utility model is achieved through the following technical solution: a box-type structure that facilitates heat dissipation of multiple components, including a box body, in which multiple components are installed;

[0010] Multiple isolation aluminum plates are vertically arranged inside the box, and each component is installed on the side of the isolation aluminum plate; the isolation aluminum plate has a hollow inner cavity A, and a heat dissipation hole communicating with the central control inner cavity A is opened on the side of the isolation aluminum plate on which the component is installed.

[0011] The bottom plate of the enclosure has a central control cavity B, and the upper surface of the bottom plate has multiple docking holes a that communicate with the central control cavity B; the lower end face of the isolation aluminum plate has multiple docking holes b that communicate with the central control cavity A; when the isolation aluminum plate is vertically fixed on the bottom plate, the docking holes a and b are docked, so that the hollow cavity B, docking holes a, docking holes b, central control cavity A, and heat dissipation holes are connected.

[0012] The box is also equipped with a fan, which is connected to the central control cavity A.

[0013] In a preferred embodiment of this solution, when each of the aforementioned components is installed on the side of the insulating aluminum plate, there is a certain gap between the corresponding component and the side of the insulating aluminum plate, forming a structure in which the gas blown out of the heat dissipation holes can flow.

[0014] In a preferred embodiment of this solution, the lower end of the aluminum isolation plate has lugs on both sides, and the lugs are fixed to the base plate by screws.

[0015] In a preferred embodiment of this solution, multiple insulating aluminum plates divide the interior of the enclosure into multiple insulating cavities, including a fan cavity A, a battery pack cavity B, a shielding cavity C, and a folding telescopic column cavity D. The battery pack cavity B has at least one wall that is a side wall of the enclosure, and this side wall has a grid opening; the shielding cavity C has at least one wall that is a side wall of the enclosure; the fan cavity D is not adjacent to the shielding cavity.

[0016] In a preferred embodiment of this solution, the shielding cavity C is connected to the folding telescopic column cavity D; a separate isolation aluminum plate is provided inside the shielding cavity C, and a shielding circuit board is provided on the side of the isolation aluminum plate, and multiple heat dissipation aluminum strips are also attached to the back of the shielding circuit board.

[0017] In a preferred embodiment of this solution, a fan is installed in the fan cavity A; a battery pack is fixed to the bottom surface of the battery pack cavity B, and a control circuit board and a router are installed on the inner wall of the cavity; a shield is installed in the shield cavity C by a separate insulating aluminum plate, and a small speaker is also installed in the shield cavity C; a folding telescopic column is installed in the folding telescopic column cavity D, and a camera and a flat panel display are installed on the folding telescopic column.

[0018] In a preferred embodiment of this solution, the enclosure is provided with an openable / accessible top cover; a handle is provided on the front side of the enclosure; and at least one side of the enclosure, on the left, right, and rear sides, is designed as a magnetic structure that allows the side panel to be opened.

[0019] To facilitate understanding, the core design principles of this solution will be explained as follows:

[0020] Because in the existing box-type structure used for examinations, each component is directly installed on the bottom and side walls of the box, the battery pack and control circuit board inside the box will generate a lot of heat, which will have an adverse effect on the shielding device.

[0021] Therefore, in this solution: ① By setting multiple vertical insulating aluminum plates, each insulating aluminum plate divides the inside of the enclosure into multiple insulating chambers. This separates the battery pack, control circuit board, and other components that generate a lot of heat from the shield, avoiding the influence of the heat emitted by these components; ② In addition, the components are installed on the sides of the vertically set insulating aluminum plates. Compared with directly installing the components on the bottom or side walls of the enclosure, this provides a larger installation area. During heat dissipation, the heat emitted by these components is less likely to cause the temperature to be particularly high in any one location, effectively dispersing the heat; ③ A fan is used... The hollow inner cavity B on the base plate, the hollow inner cavity A on the isolation aluminum plate, the heat dissipation holes, and the spacing between the isolation aluminum plate and the component components allow the air generated by the fan to cool each component component, preventing heat from accumulating inside the box and failing to dissipate properly. In addition, this structure eliminates the need for dedicated air-cooling pipes inside the box, maintaining its simplicity. ④ Other cooling designs were also implemented for the shield, such as connecting the shield cavity to the bent telescopic column cavity, providing heat dissipation aluminum strips on the back of the shield, and making the right side of the shield cavity's inner wall an openable magnetic type, which facilitates good heat dissipation from the shield.

[0022] This utility model has the following advantages:

[0023] (1) The heat dissipation effect is good throughout the entire box;

[0024] a. The enclosure is divided into multiple separate isolation chambers by an aluminum isolation plate, which prevents the heat generated by each component from affecting each other and improves the heat dissipation effect; b. The vertically arranged aluminum isolation plate increases the installation area of ​​each component, preventing heat concentration inside the enclosure and improving the heat dissipation effect; c. Each isolation chamber is cooled separately by the fan, the hollow inner cavity B on the base plate, the hollow inner cavity A on the aluminum isolation plate, the heat dissipation holes, and the distance between the aluminum isolation plate and the component, further improving the heat dissipation effect;

[0025] (2) The shield has a good cooling effect and avoids the effects of high temperature;

[0026] In addition to the points mentioned in (1) above, the back of the shield is also equipped with heat dissipation aluminum strips, the shielding cavity where the shield is located is connected to the bending telescopic column cavity, and the inner wall of the box on the right side of the shield cavity is an openable magnetic type, so as to ensure that the performance of the shield is not affected by high temperature.

[0027] (3) The overall internal structure of the box is simple;

[0028] Despite the air-cooled airflow structure, the absence of air-cooled piping keeps the entire enclosure simple. Attached Figure Description

[0036] The present invention will be further described below with reference to the accompanying drawings, but the scope of protection of the present invention is not limited to the following description.

[0037] It should be noted that the orientation or positional relationship indicated by terms such as "left" and "right" is based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship that the product of this utility model is usually placed in during use, or the orientation or positional relationship that is commonly understood by those skilled in the art. Such terms are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0038] It should be noted that, unless otherwise specified, the embodiments and features and technical solutions in the present invention can be combined with each other.

[0039] like Figures 1-6 As shown, this specific embodiment discloses a box-type structure that facilitates heat dissipation for multiple components, including a box body 10. Multiple isolation aluminum plates 20 are vertically arranged inside the box body 10, and the isolation aluminum plates 20 divide the box body 10 into multiple isolation cavities. Multiple corresponding components are installed on the cavity walls of each isolation cavity, that is, on the side of the isolation aluminum plate 20.

[0040] Among them, the insulating aluminum plate 20 has a certain thickness, and the heat insulation aluminum plate 20 has a central cavity A; multiple heat dissipation holes 21 are opened on the side of the heat insulation aluminum plate 20 on which the component is installed, and the heat dissipation holes 21 are connected to the central cavity A; it should be noted that an insulating aluminum plate 20 has two large surfaces - namely the front and the back, as well as the upper surface and the lower surface, and two smaller side surfaces, while the component is generally placed on the front and the back;

[0041] The bottom plate 11 of the housing 10 has a central cavity B, and the upper surface of the bottom plate 11 has a plurality of docking holes a communicating with the central cavity B; and the lower end face of the isolation aluminum plate 20 has a plurality of docking holes b22 communicating with the central cavity A.

[0042] When the aluminum isolation plate 20 is vertically installed on the base plate 11, the docking hole b22 of the aluminum isolation plate 20 is docked with the docking hole a of the base plate 11, so that the hollow inner cavity B → docking hole a → docking hole b22 → hollow inner cavity A - heat dissipation hole 21 are connected.

[0043] In addition, a fan 30 is installed inside the housing 10, and the fan 30 is connected to the hollow inner cavity B of the bottom plate 11 through a pipe.

[0044] When the fan 30 is working, the generated air flows sequentially through the hollow inner cavity B → docking hole a → docking hole b22 → hollow inner cavity A → heat dissipation hole 21. The air blown out from the heat dissipation hole 21 dissipates heat from the corresponding components.

[0045] The advantages of this design are: a. Each component is mounted on a vertically arranged aluminum isolation plate 20. Compared to placing the components on the bottom or sides of the enclosure 10, the multiple aluminum isolation plates 20 in this design create a larger installation area, allowing the components to be spaced further apart during installation and preventing heat concentration; b. Air cooling is achieved through the fan 30 → hollow inner cavity B → docking hole a → docking hole b22 → hollow inner cavity A → heat dissipation hole 21; c. During air cooling, the aluminum isolation plates 20 divide the enclosure 10 into multiple isolation chambers, allowing the air to flow independently within each chamber, preventing heat generated by other components from concentrating at the shield and affecting its performance; d. The entire air cooling circuit does not use unnecessary pipes, maintaining a clean and simple enclosure; e. Through the aforementioned effects of a, b, and c, good heat dissipation is ensured for all components within the enclosure 10.

[0046] Furthermore, when the various components are installed on the side of the isolation aluminum plate 20, they are installed using bolts. During installation, rubber washers are inserted into the bolts to create a certain gap between the component and the side of the isolation aluminum plate 20. This allows the air blown out from the heat dissipation holes 21 to flow more effectively after hitting the component.

[0047] Optionally, the aluminum isolation plate 20 has integrated lugs 23 on both sides at the lower end. When the aluminum isolation plate 20 is installed, the lugs 23 are fixed to the base plate 11 by screws.

[0048] In this embodiment, the housing 10 is provided with an openable / accessible top cover 12; a handle is provided on the front side of the housing 10. The handle facilitates the lifting of the entire device into the corresponding classroom for easy handling.

[0049] The structure of the housing 10 will be further explained below.

[0050] When multiple insulating aluminum plates 20 divide the interior of the housing 10 into multiple insulating cavities, the insulating cavities include fan cavity A, battery pack cavity B, shield cavity C, and folding telescopic column cavity D.

[0051] A fan 30 is installed in fan cavity A, which is not adjacent to shield cavity C;

[0052] Inside the battery pack cavity B, the bottom surface of the cavity is fixed with a battery pack, and the inner wall of the cavity is equipped with a control circuit board and a router. The cavity has at least one wall that is a side wall of the housing 10 and has a grid hole. The heat generated in the resistor pack cavity B is relatively large. This heat is guided through a separate isolation cavity. Some of the heat is discharged directly through the grid hole, and the other part of the heat is discharged through the top of the housing 10 when it is opened.

[0053] Inside the cavity D of the folding telescopic column, there is a folding telescopic column, on which a camera and a flat panel display are installed.

[0054] See Figure 2 , Figure 5 and Figure 6Inside the shielding cavity C, a separate isolation aluminum plate 20 is provided (not in contact with other isolation aluminum plates 20, nor with the inner wall of the enclosure 10). A shielding device (essentially a shielding circuit board with a retractable antenna) is provided on the isolation aluminum plate 20. Multiple heat dissipation aluminum strips 40 are attached to the back of the shielding circuit board. In addition, for the shielding cavity C, at least one wall is a side wall of the enclosure 10. The side panel corresponding to this side wall is magnetically attached to the enclosure 10 (for example, a magnetic strip is provided at the edge of the side panel, and it is magnetically attached to the side of the enclosure frame). During operation, the side panel can be opened. It should be noted that the shielding device generates a lot of heat during operation. Therefore, sufficient heat dissipation must be ensured. In addition to the air blown out by the heat dissipation holes 21 of the isolation aluminum plate 20 to dissipate heat from the shielding device, heat dissipation is also achieved by opening the side panel through the magnetic structure and by the heat dissipation aluminum strips 40 on the back.

[0055] Furthermore, the shielding cavity C is connected to the folding telescopic column cavity D, ensuring that the shielding device C has a sufficiently large space to ensure heat dissipation; in addition, a small speaker is also installed inside the shielding device C.

[0056] For example, see Figure 2 The internal structure of the housing 10 can be designed as follows:

[0057] The box 10 is laid flat, and an isolation aluminum plate, called the first isolation aluminum plate, is set along the left and right directions. The left end of the first isolation aluminum plate is close to the left wall of the box 10, while the right end is separated from the right wall of the box 10 by a certain distance. The first isolation aluminum plate divides the interior of the box into two spaces, front and rear.

[0058] A second aluminum partition plate is provided in front of the first aluminum partition plate, on the left half near the first aluminum partition plate, and parallel to the first aluminum partition plate. The second aluminum partition plate has a certain distance between itself and the first aluminum partition plate and the front wall of the box 10. The left end of the second aluminum partition plate is in contact with the left wall of the box 10.

[0059] A third aluminum partition plate is provided in front of the first aluminum partition plate, on the right half near the first aluminum partition plate, and parallel to the first aluminum partition plate. The third aluminum partition plate has a certain distance from the first aluminum partition plate and the front wall of the box 10. The distance between the third aluminum partition plate and the front wall of the box 10 is smaller than the distance between the second aluminum partition plate and the front wall of the box 10.

[0060] Furthermore, the right end of the second insulating aluminum plate and the left end of the third insulating aluminum plate are connected by a fourth insulating aluminum plate. Figure 2 (Not shown in the middle)

[0061] Furthermore, the right end of the third insulating aluminum plate is connected to the right end of the first insulating aluminum plate via a fifth insulating aluminum plate. Figure 2 (The middle part is not drawn).

[0062] In addition, a sixth aluminum isolation plate is provided on the right side of the fifth aluminum isolation plate, parallel to the right wall of the enclosure 10; the sixth aluminum isolation plate is spaced apart from the fifth aluminum isolation plate and also spaced apart from the right wall of the enclosure 10, the front end of the sixth aluminum isolation plate is spaced apart from the front wall of the enclosure 10, and the rear end of the sixth aluminum isolation plate is spaced apart from the rear wall of the enclosure 10. In simple terms, the sixth aluminum isolation plate is provided separately; a shield is provided on the left side of the sixth aluminum isolation plate.

[0063] A small speaker is installed at the gap between the sixth isolation aluminum plate and the cabinet 10;

[0064] It should be noted that the dimensions and shapes of the first, second, third, fourth, fifth, and sixth isolation aluminum plates are slightly different – ​​this is simply an adaptive design based on needs. However, the core concepts such as the central cavity A, heat dissipation holes 21, and docking holes b22 of each isolation aluminum plate are the same.

[0065] It should be noted that the problem to be solved by this solution is heat dissipation inside the enclosure 10. This solution mainly protects the heat dissipation structure of the entire enclosure 10. The circuit connection relationship of each component is not within the scope of protection of this solution (and was disclosed in the first generation product issued by our company as existing technology, which is also a very simple electrical connection method. For example, it can be connected as follows: router, battery pack and control circuit board are electrically connected; flat panel display and camera are electrically connected to control circuit board; small speaker and shield are electrically connected to control circuit).

[0066] The above embodiments only illustrate preferred implementation methods, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make several modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model.
