Description

Technical Field

[0001] This utility model relates to the field of controller testing technology, and in particular to a power controller testing device. Background Technology

[0002] When a vehicle's engine starts, the battery power drives the starter motor to quickly rotate the engine and start the vehicle. After the vehicle starts normally, the alternator charges the battery to ensure it stores enough power for the vehicle's operation. The charging and discharging of the battery is controlled by a controller with overvoltage, overcurrent, short-circuit, and temperature protection functions. During vehicle startup, the controller needs to withstand an average discharge current of 1000A and a peak current of approximately 1300A. Due to the large discharge current, the internal circuit board of the controller requires good soldering. To ensure product quality, each controller undergoes 3 to 5 discharge tests before leaving the factory to check the solder joint quality. During discharge testing, the detection terminals are typically connected to the controller's wiring terminals by pressing. This discharge device is similar to battery discharge testing equipment. However, compared to traditional battery discharge testing equipment, the controller also requires connecting a control line to the controller and sending a corresponding signal before the discharge test can begin. Therefore, a power controller testing device needs to be designed to enable rapid connection between the wiring terminals and the control line during controller testing, achieving automated testing. Utility Model Content

[0003] To address the aforementioned issues, this invention proposes a power controller testing device that enables rapid connection of terminals and control lines during controller testing, thereby automating the testing process.

[0004] This utility model is achieved through the following technical solution:

[0005] This utility model proposes a power controller testing device, comprising: a machine base, a limiting plate, a lifting plate, a connector, and a controller. The machine base is connected to the lifting plate via a guide rod and a lifting cylinder. The limiting plate is fixedly installed on the upper part of the machine base and is located directly below the lifting plate. The limiting plate has a limiting groove that matches the shape of the controller, and the limiting groove is used to limit the controller. A control line plug is provided on one side of the controller. The limiting plate has a sliding groove at the corresponding position. The lower part of the connector is slidably installed in the sliding groove. The connector has multiple pins, and the number and arrangement of the pins correspond to the sockets on the control line plug.

[0006] Furthermore, the limiting plate is provided with a cylinder, the extension rod of the cylinder is parallel to the slide groove, and the extension rod of the cylinder is connected to the connector.

[0007] Furthermore, clamping plates are provided on the upper part of both sides of the slide groove, and the connector is limited in the slide groove by the clamping plates.

[0008] Furthermore, the lifting plate is provided with a connecting plate, and the lifting plate has first elongated holes on both sides. The connecting plate is fixed to the lower part of the lifting plate by bolts, and the bolts pass through the first elongated holes.

[0009] Furthermore, the connecting plate is provided with a second elongated hole, the length direction of which is perpendicular to the length direction of the first elongated hole. A detection terminal is provided inside the second elongated hole, and a nut is provided on the upper part of the detection terminal. The detection terminal is fixed to the connecting plate by the nut.

[0010] Furthermore, the connecting plate is made of plastic or wood.

[0011] Furthermore, the limiting plate is provided with 1 to 3 limiting grooves, and the lifting plate is provided with a connecting plate and a detection terminal on each limiting groove.

[0012] The beneficial effects of this utility model are as follows: By setting a sliding connector on one side of the limiting plate, the connector can be pushed by a cylinder to connect with the starting power controller during testing, so that the controller can perform discharge testing smoothly. The test terminal is usually connected to the wiring terminal of the controller by pressing, which can quickly connect and improve the testing speed. Attached Figure Description

Throughout the description, the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them.

If the specific posture changes, the directional indicators will also change accordingly.

[0021] Furthermore, the use of terms such as "first" and "second" in this utility model is for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, features defined with "first" and "second" may explicitly or implicitly include at least one of the stated features. Additionally, the technical solutions of the various embodiments can be combined with each other, but only on the basis of being achievable by those skilled in the art. If the combination of technical solutions is contradictory or impossible to implement, such a combination of technical solutions should be considered non-existent and not within the scope of protection claimed by this utility model.

[0022] like Figures 1 to 5 As shown, an embodiment of this utility model provides a power controller testing device, including: a machine base 1, a limiting plate 2, a lifting plate 3, a connector 4, and a controller 8. The machine base 1 is connected to the lifting plate 3 via a guide rod 5 and a lifting cylinder 6. The limiting plate 2 is fixedly installed on the upper part of the machine base 1 and is located directly below the lifting plate 3. The limiting plate 2 is provided with a limiting groove 7 that matches the shape of the controller 8. The limiting groove 7 is used to limit the controller 8. A control line plug is provided on one side of the controller 8. The limiting plate 2 is provided with a sliding groove 9 at the corresponding position. The lower part of the connector 4 is slidably installed in the sliding groove 9. The connector 4 is provided with multiple pins 10. The number and arrangement of the pins 10 correspond to the sockets on the control line plug.

[0023] During testing, the controller 8 is placed in the limiting groove 7 of the limiting plate 2 manually or by a robotic arm. The shape of the limiting groove 7 is adapted to the controller 8 to prevent the controller 8 from being placed backwards. The upper edge of the limiting groove 7 has a chamfer to guide the controller 8, facilitating its quick placement. After the controller 8 is placed, the lifting cylinder 6 extends, causing the lifting plate 3 to descend. The detection terminal 14 on the lifting plate 3 presses against the wiring terminal on the controller 8, forming an electrical connection. The upper end of the detection terminal 14 is connected to the detector and discharge power supply inside the machine 1 via a wire. Pressing down the detection terminal 14, in addition to the electrical connection, also ensures that the controller 8 is firmly against the limiting groove 7. Subsequently, the cylinder 11 extends, pushing... The movable connector 4 moves towards the controller 8, and an electrical connection is established between the connector 4 and the control line plug through the pin 10 on the connector 4. The connector 4 is also connected to the computer on the machine tool 1 via a data cable. During testing, the computer sends a simulated signal to activate the circuit of the controller 8, realizing a discharge test. Simultaneously, during discharge, the operating parameters of the controller 8, such as temperature and internal resistance, are fed back to the computer on the machine tool 1 through the connector 4 and the control line, so that the computer can determine whether the controller 8 under test is qualified. After 3 to 5 high-current discharge tests, the cylinder 11 retracts, pulling out the connector 4. Then, the lifting plate 3 rises, and the controller 8 is removed by a robotic arm or manually, and a new controller 8 to be tested is placed in, thus realizing cyclical production. The detection terminal 14 is mainly connected to the controller 8 by pressing, which can prevent the controller 8 from being pulled up when the detection terminal 14 is raised, and cooperates with the robotic arm for loading and unloading, realizing fully automated production.

[0024] In a preferred embodiment, such as Figure 2 , Figure 3 As shown, a cylinder 11 is provided on the limiting plate 2. The telescopic rod of the cylinder 11 is parallel to the slide groove 9, and the telescopic rod of the cylinder 11 is connected to the connector 4. Through the extension and retraction of the cylinder 11, the connector 4 can be driven to slide in the slide groove 9. Since the slide groove 9 is directly opposite the control line plug on the controller 8, the connector 4 can be accurately inserted into the control line plug under the action of the cylinder 11, and make electrical connection with the terminal in the plug. This facilitates signal transmission between the computer and the controller 8, so that the controller 8 can conduct the circuit during the discharge test.

[0025] In a preferred embodiment, clamping plates 12 are provided on the upper part of both sides of the slide groove 9. The connector 4 is limited in the slide groove 9 by the clamping plates 12. The function of the clamping plates 12 is to block the lower part of the connector 4 above, thereby constraining the connector 4 so that the connector 4 can only slide along the slide groove 9 and will not slide out of the slide groove 9.

[0026] In a specific embodiment, such as Figure 4 , Figure 5As shown, the lifting plate 3 is provided with a connecting plate 13. The lifting plate 3 has first elongated holes on both sides. The connecting plate 13 is fixed to the lower part of the lifting plate 3 by bolts, which pass through the first elongated holes. The position of the connecting plate 13 can be adjusted through the first elongated holes, so that after the lifting plate 3 is lowered, the detection terminal 14 can be accurately pressed onto the wiring terminal of the controller 8 to achieve electrical connection.

[0027] In one specific embodiment, the connecting plate 13 is provided with a second elongated hole, the length direction of which is perpendicular to the length direction of the first elongated hole. A detection terminal 14 is disposed in the second elongated hole, and a nut is provided on the upper part of the detection terminal 14. The detection terminal 14 is fixed to the connecting plate 13 by the nut. Both the first and second elongated holes are used for position adjustment of the detection terminal 14, which facilitates the position adjustment of the detection terminal 14 when testing controllers 8 of different specifications. The discharge current during testing can reach more than 1300A. Therefore, the detection terminal 14 is made of copper with good conductivity, and the diameter of the detection terminal 14 is relatively large to ensure good electrical connection.

[0028] Specifically, the connecting plate 13 is made of plastic or wood. The plastic or wood material serves as insulation to prevent short circuits caused by electrical connections between the detection terminals 14. Furthermore, the plastic or wood connecting plate 13 can deform to a certain extent after being pressed down, so that the detection terminals 14 fit more closely to the wiring terminals on the controller 8, ensuring a good electrical connection.

[0029] In one specific embodiment, the limiting plate 2 is provided with 1 to 3 limiting grooves 7, and the lifting plate 3 is provided with a connecting plate 13 and a detection terminal 14 on each limiting groove 7. During detection, multiple controllers 8 can be tested at the same time, thereby improving the detection efficiency.

[0030] Of course, there may be other implementations of this utility model. Based on this implementation, other implementations obtained by those skilled in the art without any creative effort are all within the scope of protection of this utility model.
