Description

Technical Field

[0001] This utility model relates to the field of display screen testing, and more specifically, to a testing device that can be quickly disassembled and assembled. Background Technology

[0002] The purpose of the test board for automotive electronic displays is to simulate the functions of a domain controller host and to test the functions and performance of the display. The test board mainly consists of a motherboard and an adapter board. The motherboard is a universal design that can be reused and is suitable for the development needs of all projects, while the adapter board needs to develop corresponding interfaces according to different displays.

[0003] Test boards typically contain numerous components and require specific protection to prevent short circuits and impact damage. The conventional approach is to install protective plates on both sides of the test board and connect them with screws. After a project's testing is completed, the adapter board needs to be disassembled and replaced. The existing protection structure requires tightening multiple screws, which is time-consuming and labor-intensive. Since a large number of test boards need to be replaced for each project, this creates a significant workload for testing personnel and impacts testing efficiency. Utility Model Content

[0004] The purpose of this invention is to provide a test device that can be quickly assembled and disassembled. It has a reasonable structure, can effectively protect the test board, and can also realize the quick installation and disassembly of the adapter board, thereby improving the testing efficiency.

[0005] A quick-assembly and disassembly testing device includes an upper protective plate, a lower protective plate, and a testing plate. The testing plate is detachably suspended and supported between the upper and lower protective plates. The upper protective plate has hooks at both ends, and the lower protective plate has latches at both ends corresponding to the hooks. The latches are detachably connected to the hooks.

[0006] In the above technical solution, the upper and lower protective plates are respectively equipped with hooks and latches. When the test plate needs to be replaced, the latch can be rotated to separate it from the hook, thereby quickly separating the upper and lower protective plates and facilitating the removal and replacement of the test plate. After the test plate is replaced, the latch is fastened to the hook, which can quickly connect the upper and lower protective plates and fix the test plate. The operation is simple and convenient, effectively improving the efficiency of test plate replacement and thus improving the efficiency of testing.

[0007] Furthermore, the lower protective plate is provided with several support columns, and the upper protective plate is provided with pressure rods corresponding to the support columns. The top surface of the support column is provided with a pin extending vertically upward. The pressure rod is provided with a positioning hole. The pin passes through the test plate and extends into the positioning hole to clamp the test plate between the pressure rod and the support column.

[0008] In the above technical solution, the support column abuts against the lower end face of the test plate, thereby supporting the test plate. The upper end of the support column is equipped with a pin, which passes through the corresponding through hole in the test plate to position the test plate. A pressure rod then presses the support column down onto the upper surface of the test plate, while the pin extends into the corresponding positioning hole, thus clamping the test plate between the upper and lower protective plates. The structure is stable and reliable, and easy to assemble and disassemble.

[0009] Furthermore, the latch includes a lever, a pin, and a retaining ring. The lever is rotatably connected to the lower protective plate via the pin, and the retaining ring is rotatably connected to the lever.

[0010] In the above technical solution, the lever is rotatably connected to the lower protective plate via a pin, allowing the lever to rotate relative to the lower protective plate. This causes the buckle to move closer to or further away from the hook. The buckle can be rotated to latch onto the hook or detached from the hook, thus enabling quick assembly and disassembly of the upper and lower protective plates.

[0011] Furthermore, the end of the lever away from the pin is provided with an arc-shaped actuating surface.

[0012] In the above technical solution, by setting a toggle surface, it is easier to rotate the toggle block, making the operation more convenient.

[0013] Furthermore, the test board includes a main board, an adapter board, and several threaded connectors. The main board is provided with several mounting posts, and the threaded connectors pass through the adapter board and are connected to the mounting posts.

[0014] In the above technical solution, the motherboard is equipped with mounting posts. By screwing on the threaded connector, the adapter board can be connected or separated from the motherboard, which facilitates the replacement of the adapter board and thus improves testing efficiency.

[0015] Furthermore, the adapter board is provided with several adapter ports.

[0016] In the above technical solution, the adapter port can be connected to an external display screen to be tested, thereby enabling testing of the display screen.

[0017] Furthermore, the lower protective plate is provided with limiting blocks at both ends for limiting the position of the test plate.

[0018] In the above technical solution, the limiting block can limit the test board from both ends, which facilitates the alignment of the test board during installation and reduces the difficulty of operation.

[0019] Furthermore, both the upper and lower protective plates are made of acrylic sheets.

[0020] In the above technical solution, both the upper and lower protective plates are made of acrylic sheets, which can effectively protect the test board and are inexpensive, making them suitable for bulk purchase.

[0021] Compared with the prior art, the beneficial effects of this utility model are as follows: the upper protective plate and the lower protective plate are respectively provided with hooks and latches. When the test plate needs to be replaced, the latches can be separated from the hooks, thereby allowing the upper and lower protective plates to be quickly separated and the test plate to be easily removed for replacement. Similarly, after the test plate is replaced, the latches can be fastened to the hooks to quickly connect the upper and lower protective plates and fix the test plate. The operation is simple and convenient, effectively improving the efficiency of test plate replacement and thus improving the efficiency of testing. Attached Figure Description

Detailed Implementation

[0027] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. The components of the embodiments of this application described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0028] Therefore, the following detailed description of the embodiments of this application provided in the accompanying drawings is not intended to limit the scope of the claimed application, but merely to illustrate selected embodiments of the application. All other embodiments obtained by those skilled in the art based on the embodiments of this application without inventive effort are within the scope of protection of this application.

[0029] Please refer to Figures 1 to 3In a preferred embodiment, the quick-disassembly and detachable testing device of the present invention mainly includes an upper protective plate 1, a lower protective plate 2, and a testing plate 3. The testing plate 3 is detachably suspended and supported between the upper protective plate 1 and the lower protective plate 2. The upper protective plate 1 is provided with hooks 11 at both ends, and the lower protective plate 2 is provided with latches 21 at both ends corresponding to the hooks 11. The latches 21 and the hooks 11 can be detachably connected.

[0030] For example, both the upper protective plate 1 and the lower protective plate 2 are generally rectangular flat plates made of acrylic material, positioned vertically opposite each other. The test plate 3 is suspended between the upper protective plate 1 and the lower protective plate 2. There are two hooks 11, mirror-image positioned at both ends of the upper protective plate 1 along its length. Correspondingly, there are two latches 21, positioned at both ends of the lower protective plate 2 along its length. The latches 21 can be connected to or disconnected from the corresponding hooks 11. When the test plate 3 needs to be replaced, the latches 21 can be rotated to separate from the hooks 11, thus quickly separating the upper protective plate 1 and the lower protective plate 2, facilitating the removal and replacement of the test plate 3. After the test plate 3 is replaced, the latches 21 are fastened to the hooks 11, quickly connecting the upper protective plate 1 and the lower protective plate 2 and securing the test plate 3. The operation is simple and convenient, effectively improving the replacement efficiency of the test plate 3, and consequently, the testing efficiency.

[0031] In this embodiment, the lower protective plate 2 is provided with a plurality of support columns 22, and the upper protective plate 1 is provided with a pressure rod 12 corresponding to the support columns 22. The top surface of the support column 22 is provided with a pin 23 extending vertically upward. The pressure rod 12 is provided with a positioning hole. The pin 23 passes through the test plate 3 and extends into the positioning hole to clamp the test plate 3 between the pressure rod 12 and the support column 22.

[0032] For example, four support columns 22 are respectively located at the four corners of the upper end face of the lower protective plate 2. Four pressure rods 12 are correspondingly located at the four corners of the lower end face of the upper protective plate 1. A pin 23 extends vertically upward from the center of the top surface of the support column 22. The test plate 3 has a through hole corresponding to the pin 23, the diameter of which is larger than the diameter of the pin 23 but smaller than the diameter of the support column 22, allowing the pin 23 to pass through the through hole and simultaneously supporting the test plate 3 through the support column 22. A positioning hole (not shown) is provided on the lower end face of the pressure rod 12, the diameter of which matches the diameter of the pin 23, allowing the pin 23 to extend into the positioning hole, thereby fixing the relative positions of the upper protective plate 1 and the lower protective plate 2. The pressure rod 12 presses down on the upper surface of the test plate 3 from top to bottom, cooperating with the support columns 22 to suspend the test plate 3 between the upper protective plate 1 and the lower protective plate 2. The structure is stable and reliable, and easy to assemble and disassemble.

[0033] In this embodiment, the latch 21 includes a lever 211, a pin 212, and a retaining ring 213. The lever 211 is rotatably connected to the lower protective plate 2 via the pin 212, and the retaining ring 213 is rotatably connected to the lever 211. Specifically, the pin 212 passes through the lower protective plate 2, one end of the lever 211 is rotatably connected to the pin 212, and one end of the retaining ring 213 is rotatably connected to the lever 211 near the center. The lever 211 can rotate relative to the lower protective plate 2, thereby causing the end of the retaining ring 213 away from the lever 211 to move closer to or away from the hook 11. The retaining ring 213 can be rotated to latch onto the hook 11 or detached from the hook 11, thereby achieving quick assembly and disassembly of the upper protective plate 1 and the lower protective plate 2.

[0034] Preferably, the end of the lever 211 away from the pin 212 is provided with an arc-shaped actuating surface 214. By providing the actuating surface 214, the lever 211 can be rotated more easily, making operation more convenient.

[0035] In this embodiment, the test board 3 includes a main board 31, an adapter board 32, and several threaded connectors 33. The main board 31 has several mounting posts 311, and the threaded connectors 33 pass through the adapter board 32 and connect to the mounting posts 311. The threaded connectors 33 can be screws, and the mounting posts 311 can be soldered to the surface of the main board 31 using SMT (Surface Mount Technology) to ensure structural stability. The inner side of the mounting posts 311 has threaded holes (not shown). By tightening the threaded connectors 33, the adapter board 32 can be connected to or separated from the main board 31, facilitating replacement of the adapter board 32 and thus improving testing efficiency.

[0036] The adapter board 32 is provided with several adapter ports 312. Among them, the adapter ports 312 can be existing video ports, and the adapter ports 312 can be connected to an external display screen to be tested, so as to test it.

[0037] In a preferred embodiment, the lower protective plate 2 is provided with limiting blocks 24 at both ends for limiting the test plate 3. The limiting blocks 24 can limit the test plate 3 from both ends, which facilitates the alignment of the test plate 3 during installation and reduces the difficulty of operation.
