Description

Technical Field

[0001] The invention relates to the technical field of automobile variable testing, in particular to a test bench for intelligent automobile variable processing. Background Art

[0002] New energy power system is an important technical route for commercial vehicles. The three core parts of the new energy power system include power batteries, drive motors, and motor controllers. As core components, motors and motor controllers need to be professionally designed and tested during the automotive research and development stage to ensure the power, economy and control stability of the power system. When testing the vehicle, the power and speed variables in the drive motor need to be tested multiple times to determine whether the drive motor can work stably in the smart car, which also improves the safety of smart car driving.

[0003] Based on the above, the inventors have found that the existing test bench for intelligent automobile variable processing has the following main deficiencies. For example, with the development of new energy electric vehicles, various types of automobiles have appeared on the market, and the models of drive motors in the automobiles are different. As a result, when the test bench is faced with different models of drive motors, the shapes and lengths of the drive motors are different, resulting in the test bench being unable to fix different models of drive motors, which affects the detection of drive motor variables. Summary of the invention

[0004] In view of the above problems, the present invention provides a test bench for intelligent automobile variable processing.

[0005] In order to achieve the above-mentioned object, the present invention is implemented through the following technical solutions: a test bench for intelligent automobile variable processing, which structure includes a test bench and a test body, the top of the test bench is provided with a top cover, and the top cover is supported by two support rods, and the control panel is arranged on the top of the left side of the test bench, the test information panel is installed on the left end surface of the test bench, and the test body is fixedly installed in the middle position inside the test bench; The detection body includes a support plate, a slide rail, a detection device, and a fixing structure. The slide rails are respectively fixed to the end surfaces of the support plate, and the detection device and the fixing structure are respectively installed on the end surfaces of the slide rails; The detection device comprises a detection structure, an electric sliding block, and a power line. The inner bottom end of the detection structure is provided with an electric sliding block, and the electric sliding block can slide left and right on the end surface of the slide rail, and the power line is connected to the end surface of the detection structure for power supply; The detection structure includes a support frame, a clamping device, a power supply regulator, and a speed monitor. The clamping device is fixedly installed on the inner left side of the support frame, and the support frame is fixedly connected to the electric sliding block. The speed monitor is arranged on the inner left side of the support frame, and the power supply regulator is installed on the upper end of the speed monitor. The clamping device includes a mounting frame, a threaded rod, a servo motor, and a clamping block. The mounting frame is fixedly mounted on the left side of the interior of the support frame, and the threaded rod is rotatably connected to both sides of the interior of the mounting frame. The servo motor is fixedly mounted inside the mounting frame and meshed with the threaded rod. Two clamping blocks are provided, and the end faces of the clamping blocks are provided with threads that match the threads of the threaded rod. Symmetrical threads are arranged on both sides of the threaded rod, and the rotation of the threaded rod can drive the clamping block to move toward the middle or toward both ends at the same time.

[0006] The end face of the clamping block is L-shaped, and the drive motor to be tested can be supported and clamped by the clamping block.

[0007] The drive motor to be tested is placed on the end faces of the two clamping blocks, and the servo motor is used to drive the threaded rod to rotate forward, so that the two clamping blocks and the threaded rod can cooperate to move toward the middle to support and clamp the bottom of the drive motor, and then the electric sliding block and the slide rail are used to drive the support frame to move to the left, so that the drive motor can be against the end face of the fixed structure, and the rotating head of the drive motor and the speed monitor are connected together to generate friction for variable detection.

[0008] Furthermore, the fixing structure includes a clamping frame, a clamping top block, a limit block, and a threaded locking block. The clamping frame is threadedly fixed on the top end face of the support plate, and the clamping top block is inserted and installed on the left end face of the clamping frame.

[0015] Furthermore, the anti-skid pad is made of rubber, and the middle of the anti-skid pad is hollow, so it can be disassembled at the end surface of the support block.

Two clamping blocks 44 are provided, and the end faces of the clamping blocks 44 are provided with threads that are threadedly matched with the threaded rod 42. Symmetrical threads are arranged on both sides of the threaded rod 42 , and the rotation of the threaded rod 42 can drive the clamping block 44 to move toward the middle or toward both ends at the same time.

[0029] The end surface of the clamping block 44 is L-shaped, and the drive motor to be tested can be supported and clamped by the clamping block 44 .

[0031] Based on the above embodiment, the specific working principle is as follows: when the drive motor needs to be detected, the drive motor to be detected is placed on the end faces of the two clamping blocks 44, and then the servo motor 43 drives the threaded rod 42 to rotate forward, so that the two clamping blocks 44 cooperate with the threaded rod 42 to move toward the middle to support and clamp the bottom of the drive motor.

[0033] By adjusting the positions of the limit block 343 and the thread locking block 344 on the clamping top block 342 , the clamping top block 342 can be adjusted forward or backward.
