Description

Technical Field

[0001] The utility model relates to the field of testing, in particular to a quick locking structure of an automobile function testing module. Background Art

[0002] As vehicles become increasingly intelligent, the number of functional modules within them continues to increase. To ensure vehicle safety and provide an excellent driving experience, these modules must undergo rigorous testing after production to verify that they meet established standards. LVDS test equipment plays a crucial role in vehicle electronics testing. This type of test equipment integrates multiple Flexmedia modules, each corresponding to a specific signal point, to monitor the operating status of multiple key signal points.

[0003] However, in practice, disassembly and maintenance of Flexmedia modules can be quite cumbersome. These modules are typically securely fastened to the drawer of LVDS test equipment with screws. When a module malfunctions, requires repair or maintenance, technicians often need to use tools such as screwdrivers to disassemble it. This traditional disassembly method is not only time-consuming and labor-intensive, but also reduces work efficiency, becoming a bottleneck restricting the efficient operation of the test equipment. Utility Model Content

[0004] The utility model aims to overcome the deficiencies of the prior art and to provide a quick locking structure for an automobile function test module.

[0005] To achieve the above-mentioned object, the technical solution adopted by the present invention is: a quick locking structure for an automobile functional test module, comprising a drawer slidably mounted on a cabinet, a plurality of bayonet holes horizontally spaced apart on the front face of the drawer for securing an end of the test module, and a plurality of cam locking assemblies disposed within the drawer and positioned opposite the bayonet holes for quickly securing the other end of the test module;

[0006] The cam locking assembly includes a bracket, a connecting shaft passing horizontally through the bracket, a claw arranged at one end of the connecting shaft at the bayonet and capable of extending into the notch at the bottom of the test module, a toggle member arranged at the other end of the connecting shaft, and a reset spring sleeved on the connecting shaft and located between the claw and the bracket; the toggle member includes a cam rotatably connected to the connecting shaft and a toggle handle connected to the cam; when the toggle handle drives the cam to rotate, the cam will press against the bracket, overcome the elastic force of the reset spring, and drive the claw to hook the notch at the bottom of the test module through the connecting shaft.

[0007] Preferably, a connecting groove placed perpendicular to the cam axis is provided in the middle of the cam; the connecting shaft extends into the connecting groove and is rotatably connected to the cam through a pin shaft.

[0008] Preferably, the claw and the connecting shaft are integrally injection molded.

[0009] Preferably, the bracket is fixed in the drawer by screws, and multiple cam locking assemblies can share one bracket.

[0010] Preferably, a hollow area is provided at the bottom of the drawer between the bayonet and the cam locking assembly.

[0011] Preferably, a plurality of reinforcing sheets are provided in the hollow area and are spaced apart and placed parallel to the test module.

[0012] Due to the application of the above technical solution, the utility model has the following advantages compared with the prior art:

[0013] Since one end of the test module is in a stepped shape and a notch is provided at the bottom of the other end, the utility model provides a bayonet for clamping the stepped end of the test module according to the structure of the test module itself, and a cam locking assembly for hooking the notch at the bottom of the test module. Through the cooperation of the bayonet and the cam locking assembly, the test module can be quickly locked, which greatly improves work efficiency and has the advantages of simple structure, easy operation and low cost.

[0021] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0022] Attachment Figure 1-5 The automotive functional test module quick lock structure of the present invention comprises a drawer 1 slidably mounted on a cabinet, a plurality of bayonet holes 3 horizontally spaced apart on the front of the drawer 1 for securing the end of the test module 2, and a plurality of cam locking assemblies 4 disposed within the drawer 1 and opposite to the bayonet holes 3 for quickly securing the other end of the test module 2.

[0023] The cam locking assembly 4 includes a bracket 41, a connecting shaft 42 that passes horizontally through the bracket 41, a claw 43 arranged at one end of the connecting shaft 42 located at the bayonet 3 and can extend into the bottom notch 21 of the test module 2, a toggle member 44 arranged at the other end of the connecting shaft 42, and a return spring 45 that is sleeved on the connecting shaft 42 and located between the claw 43 and the bracket 41; the toggle member 44 includes a cam 441 that is rotatably connected to the connecting shaft 42 and a toggle handle 442 connected to the cam 441.

[0024] During operation: the staff picks up the test module 2, tilts the test module 2, and then inserts the stepped end of the test module 2 into the bayonet 3 downward, and preliminarily positions it through the bayonet 3; then presses down the other end of the test module 2 to make the claw 43 extend into the bottom notch 21 of the test module 2; finally, pushes the handle 442 downward to drive the cam 441 to rotate, and the cam 441 will resist the bracket 41, overcome the elastic force of the reset spring 45, and drive the claw 43 through the connecting shaft 42 to hook the bottom notch 21 of the test module 2, thereby achieving quick locking; when the handle 442 is pushed from vertical to horizontal, it reaches a self-locking state.

[0025] Further, if Figure 4 As shown, a connecting groove 443 is provided in the middle of the cam 441 and is placed perpendicular to the axis of the cam 441; the connecting shaft 42 extends into the connecting groove 443 and is rotatably connected to the cam 441 through a pin 444; since the connection position between the cam 441 and the connecting shaft 42 is located in the middle of the cam 441, when the cam 441 is turned, the connecting shaft 42 is subjected to more uniform force.

[0026] Furthermore, the claw 43 and the connecting shaft 42 are integrally injection-molded, which not only facilitates manufacturing and reduces production costs, but also facilitates assembly.

[0027] Further, if Figure 2 As shown, the bracket 41 is fixed in the drawer 1 by screws, wherein the four cam locking assemblies 4 share one bracket 41 , which can greatly improve the installation speed of the cam locking assemblies 4 .

[0028] Further, if Figure 2As shown, a hollow area 11 is provided between the bayonet 3 and the cam locking assembly 4 at the bottom of the drawer 1 , which not only facilitates heat dissipation of the test module 2 , but also facilitates taking and placing the test module 2 .

[0029] Further, if Figure 2 As shown, a plurality of reinforcing sheets 5 are provided in the hollow area 11 at intervals and placed parallel to the test module 2 , which play a reinforcing role and prevent the front of the drawer 1 from deformation.

[0030] The above are only specific application examples of the present invention and do not constitute any limitation on the scope of protection of the present invention. Any technical solution formed by equivalent transformation or equivalent replacement shall fall within the scope of protection of the present invention.
