Description

Technical Field

[0001] This utility model relates to the field of automotive parts testing technology, and in particular to an experimental testing device for a new energy vehicle motor controller. Background Technology

[0002] A motor controller is an internal integrated circuit control module used to control a motor to rotate in a set direction, speed and response time. It is one of the key components in new energy vehicles. After production, the motor controller needs to be tested for current using a testing device.

[0003] Under normal circumstances, the control performance of the motor controller is usually tested. However, in actual use, the motor controller needs to be installed on the car, so the physical characteristics of the motor controller are also very important.

[0004] However, current equipment cannot perform drop tests on motor controllers, so it is impossible to test the impact resistance of motor controllers. Therefore, a test equipment for new energy vehicle motor controllers is proposed to solve the above-mentioned problems. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies where current equipment cannot perform drop tests on motor controllers, thus failing to test the impact resistance of motor controllers. Therefore, this invention proposes a test and inspection device for motor controllers in new energy vehicles.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A testing and inspection device for a new energy vehicle motor controller includes a base plate, four support frames fixedly mounted on the top of the base plate, and a common top plate fixedly mounted on the top of the four support frames. The testing and inspection device also includes:

[0008] The support mechanism is installed on the top of the base plate and the top of the support mechanism is connected to the bottom of the top plate. A motor controller is placed on the support mechanism.

[0009] The pneumatic mechanism is installed on the top of the base plate. One end of the pneumatic mechanism is connected to the support mechanism. The pneumatic mechanism is used to drive the support mechanism to move, so as to drive the motor controller to carry out drop impact tests.

[0010] In one possible design, the support mechanism includes a tray, which is slidably connected to the inner walls of four support frames. A motor controller is placed on top of the tray. Four limiting frames are symmetrically slidably connected through the tray. The top and bottom ends of the limiting frames are fixedly connected to the bottom of the top plate and the top of the bottom plate, respectively. The four corners of the motor controller are slidably in contact with the four limiting frames. A pop-up assembly is installed at the bottom of the tray, and the bottom of the pop-up assembly is connected to the top of the bottom plate. One end of the pneumatic mechanism is connected to the pop-up assembly.

[0011] In one possible design, the pop-up assembly includes four piston rods symmetrically fixedly mounted on the bottom of the support plate. Limiting tubes are tightly slidably sleeved on the piston rods. The bottom ends of the four limiting tubes are fixedly connected to the top of the base plate. A first compression spring is sleeved on the piston rod above the limiting tube. The top and bottom ends of the first compression spring are fixedly connected to the bottom of the support plate and the top end of the limiting tube, respectively. The same air supply component is connected to the four limiting tubes, and one end of the air supply component is connected to a pneumatic mechanism.

[0012] In one possible design, the gas supply component includes a connecting pipe that penetrates the bottom inner wall of one side of the limiting tube and is fixedly connected to the bottom inner wall of one side of the limiting tube. Multiple connecting pipes are fixedly connected to the same annular tube. A gas supply pipe is fixedly connected through one side of the inner wall of the annular tube, and one end of the gas supply pipe is connected to a pneumatic mechanism.

[0013] In one possible design, the pneumatic mechanism includes a transmission box fixedly mounted on the top of a base plate. One end of an air supply pipe extends into the transmission box and is fixedly connected to the bottom inner wall of one side of the transmission box. Four electric push rods are symmetrically fixedly mounted on the top of the transmission box. The same mounting bracket is fixedly mounted on the output shaft of the four electric push rods. A pull rod is fixedly mounted at the bottom center of the mounting bracket. A connecting bracket is fixedly mounted inside the top opening of the transmission box. The bottom end of the pull rod passes through the connecting bracket and extends into the transmission box. A piston plate is fixedly mounted on the bottom end of the pull rod. The piston plate is slidably and sealingly connected to the inner wall of the transmission box. A second compression spring is sleeved on the pull rod. The top and bottom ends of the second compression spring are fixedly connected to the bottom of the connecting bracket and the bottom of the piston plate, respectively.

[0014] In one possible design, a mounting cover is fixedly installed on the bottom inner wall of the other side of the transmission box, one side of the mounting cover extends to the outside of the transmission box, and multiple solenoid valves are fixedly installed at equal intervals on the inner wall of one side of the mounting cover, with one end of the solenoid valves extending to the outside of the mounting cover.

[0015] In this application, the motor controller to be tested is first placed on the tray. Then, four electric push rods are activated to move the mounting bracket upwards. At this time, the piston plate is moved upwards via the pull rod. When the piston plate moves upwards, a negative pressure state is created below the piston plate. This allows the gas in the four limiting tubes to be transported to the transmission box through the corresponding connecting pipes, annular pipes, and gas supply pipes. As the gas in the limiting tubes decreases, a negative pressure gradually forms, which drives the corresponding piston rod to move downwards, thus moving the tray downwards. When the tray moves downwards, it compresses the four first compression springs. The elastic potential energy of the first compression spring is increased. After the pallet is moved down to the designated position, the elastic potential energy of multiple first compression springs also reaches the required level, which can energize and open multiple solenoid valves. At this time, external gas can enter the transmission box through the solenoid valves. Then, the gas can be transported to multiple limiting pipes through the gas supply pipe, the ring pipe, and multiple connecting pipes. At this time, the piston rod can lose its limit, and the first compression spring in the force state can push the pallet to move upward with acceleration, thereby making the motor controller bounce up, so that the motor controller can undergo free fall motion, and thus a drop collision test can be performed on the motor controller.

[0016] Beneficial effects: In this utility model, the experimental testing equipment for a new energy vehicle motor controller, through a support mechanism, can retract the spring-loaded component by activating the pneumatic mechanism, thereby driving the tray to move downward. After the spring-loaded component retracts to a certain extent, the elastic component can be reset, thereby using the elastic potential energy of the spring-loaded component to drive the tray to reset upward, thus enabling the tray to reset upward in an accelerated manner, thereby pushing the motor controller upward. The motor controller will move upward in an accelerated manner. After the motor controller rises to a certain height, it can undergo free fall motion, causing the motor controller to land on the tray, thus enabling a free fall collision test on the motor controller, thereby testing the overall physical strength of the motor controller.

[0017] In this utility model, the experimental testing equipment for a new energy vehicle motor controller can use a pneumatic mechanism to push the mounting frame upward by activating four electric push rods. At this time, the piston plate can be moved upward by the pull rod. When the piston plate moves upward, a negative pressure state will appear below the piston plate. At this time, the gas in the four limiting tubes can be transported to the transmission box through the corresponding connecting pipe, annular pipe and gas supply pipe, so as to drive the four piston rods to move downward, thereby compressing the four first compression springs and increasing the elastic potential energy of the first compression springs.

[0018] After the motor controller is placed on the tray, the four electric push rods and the solenoid valve are activated to make the motor controller bounce upward, so that the motor controller can be allowed to fall freely. This allows for easy free-fall collision tests on the motor controller, thereby testing the overall physical strength of the motor controller. Attached Figure Description

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model.

[0024] Example 1: Refer to Figure 1-3 A testing device mainly includes a base plate 1, four support frames 2 are fixedly installed on the top of the base plate 1, and a top plate 3 is fixedly installed on the top of the four support frames 2, forming a stable frame structure.

[0025] A support mechanism and a pneumatic mechanism are installed on the top of the base plate 1. The support mechanism mainly consists of a support plate 5, whose four sides are slidably connected to the inner walls of four support frames 2, ensuring that the support plate 5 can move smoothly up and down within the support frames 2. The motor controller 6 is placed on top of the support plate 5. To limit the movement of the motor controller 6 on the support plate 5, four limiting frames 4 are symmetrically slidably connected through the support plate 5. The top and bottom ends of these four limiting frames 4 are fixedly connected to the bottom of the top plate 3 and the top of the base plate 1, respectively. The four corners of the motor controller 6 are in slidable contact with these four limiting frames 4, thereby ensuring that the motor controller 6 remains stable during a fall.

[0026] A spring-loaded assembly is installed at the bottom of the support plate 5. The assembly consists of four piston rods 7 symmetrically fixedly mounted on the bottom of the support plate 5. Limiting tubes 8 are slidably fitted onto the piston rods 7, and the bottom ends of these four limiting tubes 8 are fixedly connected to the top of the base plate 1. A first compression spring 9 is fitted onto the piston rod 7, located above the limiting tubes 8. The top and bottom ends of the first compression spring 9 are fixedly connected to the bottom of the support plate 5 and the top of the limiting tube 8, respectively. When the piston rods 7 slide within the limiting tubes 8, the first compression spring 9 is compressed or extended, thereby storing or releasing elastic potential energy.

[0027] To achieve gas extraction and release, the same gas delivery component is connected to the four limiting pipes 8. The gas delivery component includes a connecting pipe 10 that penetrates the inner wall of the bottom of one side of the limiting pipe 8 and is fixedly connected to the inner wall of the bottom of one side of the limiting pipe 8. The same annular pipe 11 is fixedly connected to the multiple connecting pipes 10, and a gas delivery pipe 12 is fixedly connected through the inner wall of one side of the annular pipe 11.

[0028] The pneumatic mechanism includes a transmission box 13 fixedly mounted on the top of the base plate 1. One end of the air supply pipe 12 extends into the transmission box 13 and is fixedly connected to the inner wall of the bottom side of the transmission box 13. Four electric push rods 16 are symmetrically fixedly mounted on the top of the transmission box 13, and a mounting bracket 17 is fixedly mounted on the output shaft of these four electric push rods 16. A pull rod 18 is fixedly mounted at the center of the bottom of the mounting bracket 17. The bottom end of the pull rod 18 passes through the connecting bracket 19 at the top of the transmission box 13 and extends into the transmission box 13. A piston plate 20 is fixedly mounted at the bottom end of the pull rod 18, and the piston plate 20 is slidably and sealingly connected to the inner wall of the transmission box 13. A second compression spring 21 is sleeved on the pull rod 18, and the top and bottom ends of the second compression spring 21 are fixedly connected to the bottom of the connecting bracket 19 and the bottom of the piston plate 20, respectively.

[0046] This application can be used in the field of automotive parts testing technology, or in other fields applicable to this application.

[0047] Example 2: Reference Figure 3 An improvement based on Embodiment 1: A test and inspection device for a new energy vehicle motor controller, which is applied to the field of automotive parts testing technology, wherein an installation cover 14 is fixedly installed on the bottom inner wall of the other side of the transmission box 13, one side of the installation cover 14 extends to the outside of the transmission box 13, and multiple solenoid valves 15 are fixedly installed at equal intervals on its inner wall, one end of the solenoid valve 15 extending to the outside of the installation cover 14.

[0048] When a drop impact test is required, the four electric push rods 16 are activated to push the mounting bracket 17 upward. At this time, the piston plate 20 can be moved upward by the pull rod 18. When the piston plate 20 moves upward, a negative pressure state will be formed below the piston plate 20. At this time, the gas in the four limiting tubes 8 can be transported to the transmission box 13 through the corresponding connecting pipe 10, annular pipe 11 and gas supply pipe 12, so as to drive the four piston rods 7 to move downward. At this time, the support plate 5 will move downward and compress the four first compression springs 9, so as to increase the elastic potential energy of the first compression springs 9. When the pallet 5 moves down to the designated position, the elastic potential energy of the multiple first compression springs 9 reaches the required level, which energizes the multiple solenoid valves 15. At this time, the outside gas can enter the transmission box 13 through the solenoid valves 15. Then, the gas can be transported to the multiple limiting pipes 8 through the gas supply pipe 12, the annular pipe 11, and multiple connecting pipes 10. At this time, the piston rod 7 can lose its limit, and the first compression springs 9 under force can push the pallet 5 to move upward with acceleration, thereby lifting the motor controller 6 and allowing the motor controller 6 to fall freely onto the pallet 5. This allows the motor controller 6 to undergo a drop impact test to test its overall physical strength.

[0049] However, as is well known to those skilled in the art, the working principle and wiring method of the solenoid valve 15 and the electric push rod 16 are commonplace and are all conventional methods or common knowledge. They will not be described in detail here. Those skilled in the art can make any selections according to their needs or convenience.

[0050] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
