Therefore, the heat resistance life test of the automotive control assembly is a key step to verify whether it can operate stably under different temperature conditions;

[0022] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0023] During specific implementation: As Figures 1-4 shown, an integrated test device for the life of a new energy vehicle control assembly includes: a heating table 1, and a placing groove 2 is provided on the surface of the heating table 1; an adaptation test mechanism 3, and a telescopic adaptation test mechanism 3 for performing adaptation tests on vehicle control assemblies of different sizes is arranged on one side of the heating table 1; wherein, the adaptation test mechanism 3 includes a support frame 11 fixedly installed on one side of the heating table 1, an electric push rod 31 is fixedly installed on one side of the support frame 11, an adaptation component 32 is arranged at the output end of the electric push rod 31, and a sealing component 33 is arranged on one side of the placing groove 2. During use, the control assembly of the new energy vehicle can be placed inside the placing groove 2, and then the size of the adaptation component 32 can be adjusted according to different control assemblies to match the size of the control assembly. Not only can the space be matched when covering, enabling the heating table 1 to quickly heat up, but also different sizes of control assemblies can be adapted, increasing the applicability of the test device. When the adaptation component 32 moves into the placing groove 2, the sealing component 33 can seal the outside of the adaptation component 32 to improve the heating effect.

[0024] As Figure 2 and Figure 3As shown, the adaptation component 32 includes a fixed frame 321 fixedly installed at the output end of the electric push rod 31. Moving frames 322 are arranged on both sides of the fixed frame 321. Telescopic frames 323 are fixedly installed between the two moving frames 322 and the fixed frame 321. When it is necessary to adjust the size of the test space, the positions of the two moving frames 322 can be moved to synchronously drive the telescopic frames 323 to deform, so as to quickly adjust the positions of the two moving frames 322 and synchronously adjust the test space, and different control assemblies can be matched for testing. A motor 324 is fixedly installed on the outer side of the fixed frame 321. The output end of the motor 324 extends into the fixed frame 321. A toggle plate 326 is slidably installed on the inner top wall of the fixed frame 321. A reciprocating lead screw 325 is fixedly installed at the output end of the motor 324. The reciprocating lead screw 325 penetrates through the toggle plate 326 and is slidably connected with the toggle plate 326. The reciprocating lead screw 325 is in the form of two thread grooves with the same pitch and opposite helix directions, and the two ends are connected by a transition curve. By rotating the reciprocating lead screw 325, the side of the helical groove pushes the slider placed in the helical groove to move axially back and forth. When heating, the motor 324 can be started to drive the reciprocating lead screw 325 to rotate, driving the toggle plate 326 to reciprocate on the surface of the reciprocating lead screw 325, so as to stir the internal hot air flow. When heating, the internal hot air flow can be effectively stirred through the reciprocating movement of the toggle plate 326, so that the hot air is evenly distributed in the test space, ensuring that each part of the control assembly can be evenly heated;

[0025] A plurality of moving rings 327 are fixedly installed at the bottom of the toggle plate 326. The plurality of moving rings 327 are evenly distributed at equal intervals. When the toggle plate 326 moves, the plurality of moving rings 327 at the bottom can be synchronously driven to move. The air flow in the heating space can be effectively stirred through the plurality of moving rings 327, further enhancing the circulation and distribution uniformity of the air flow. An elastic sheet 328 is fixedly installed inside the moving ring 327. The elastic sheet 328 is set in the shape of a biconcave lens. When the moving ring 327 moves, the elastic sheet 328 is synchronously driven to deform, increasing the contact area between the moving ring 327 and the air flow during movement, thereby increasing the disturbance effect on the air flow.

[0026] As Figure 2 and Figure 4As shown, the sealing component 33 includes a mounting wall 331 fixedly mounted on one side of the placement groove 2, a sealing airbag 332 is fixedly mounted on the surface of the mounting wall 331, and an air pump 333 is arranged on one side of the sealing airbag 332, and gas can be input into the sealing airbag 332 through the air pump 333 to expand the sealing airbag 332, so that the sealing airbag 332 is close to the outer side of the adapter component 32, and can adapt to adapter components 32 of different sizes for synchronous sealing, and the air pump 333 is fixedly mounted on the surface of the heating platform 1, and the air pump 333 and the sealing airbag 332 are fixedly connected through the delivery pipe 335, and the air pump 333 can stably deliver gas to the sealing airbag 332 through the delivery pipe 335, so that the sealing airbag 332 can be stably deformed.

[0027] When the utility model is in use, when the size of the test space needs to be adjusted, the movable frames 322 on both sides can be moved to synchronously drive the telescopic frames 323 to deform, so that the positions of the movable frames 322 on both sides can be quickly adjusted to synchronously adjust the test space, and different control assemblies can be matched for testing. When heating, the motor 324 can be started to drive the reciprocating screw 325 to rotate, and the toggle plate 326 can be driven to reciprocate on the surface of the reciprocating screw 325 to stir the internal hot air flow. When heating, the reciprocating motion of the toggle plate 326 can effectively stir the internal hot air flow, so that the hot air It is evenly distributed in the test space to ensure that each part of the control assembly can be evenly heated. When the toggle plate 326 moves, it can synchronously drive the multiple moving rings 327 at the bottom to move. When the moving ring 327 moves, it synchronously drives the elastic sheet 328 to deform, thereby increasing the contact area between the moving ring 327 and the airflow when it moves, thereby increasing the disturbance effect on the airflow. Gas can be input into the sealing airbag 332 through the air pump 333 to expand the sealing airbag 332, so that the sealing airbag 332 is close to the outside of the adapter component 32, and can adapt to adapter components 32 of different sizes for synchronous sealing.

[0028] In addition, it should be understood that although the present specification is described according to implementation modes, not every implementation mode contains only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
