However, this solution has a drawback: it is difficult to accurately control the position of the power source when placing it, making it difficult to directly align the positive and negative poles of the power source with the conductive posts of the pressure cap in the testing device. This requires staff to repeatedly adjust the placement of the power source, which not only increases the intensity of manual operation but also seriously affects the continuity of the testing process and the overall testing efficiency.

[0012] Preferably, each of the two second wedge plates has a movable block fixedly connected to its outer surface, and each of the two movable blocks has a third spring fixedly connected to its outer surface.

[0026] The embodiments of the present invention will now be described in detail with reference to the accompanying drawings. Those skilled in the art should understand that these embodiments are merely illustrative of the technical principles of the present invention and are not intended to limit the scope of protection of the present invention.

[0027] As attached Figure 1-7 As shown, an energy storage power supply performance testing device includes a test box 1 with a front opening. A shell 2 with a bottom opening is fixedly connected inside the test box 1. The shell 2 supports the power supply body 3 to be tested. The power supply body 3 is placed without a top cover to allow contact with subsequent conductive posts 6. A pressure cover 5 is provided on the top of the shell 2. Two conductive posts 6 are fixedly embedded on the upper surface of the pressure cover 5, corresponding to the positive and negative terminals of the power supply body 3, respectively, for transmitting electrical signals during testing. A lifting plate 10 is fixedly connected to the outer surface of the pressure cover 5. The lifting plate 10 is slidably connected inside the test box 1, and a pressing component corresponding to a centering mechanism is provided below the lifting plate 10. The purpose of the lifting plate 10 is to drive the pressing component to move synchronously, ensuring the smoothness of the pressing action. Simultaneously, the sliding cooperation between the lifting plate 10 and the test box 1 restricts the movement direction of the pressure cover 5, preventing the pressure cover 5 from shifting and causing the conductive posts 6 to fail to accurately connect with the positive and negative terminals of the power supply body 3.

[0028] A centering mechanism is provided on the housing 2. The centering mechanism includes two first movable plates 13 slidably connected inside the housing 2. The two first movable plates 13 are fixedly connected to the side of each other that is far apart from each other, and the other side of the first wedge plate 14 slides through the housing 2, so that the first wedge plate 14 can contact and bear force with the fourth wedge plate 29. The two first movable plates 13 are fixedly connected to the side of each other that is close to each other. The two U-shaped seats 15 are rotatably installed inside the two U-shaped seats 15, and the two positioning wheels 16 are located on both sides of the power supply body 3. The positioning wheels 16 are rotatably installed, so that they can rotate with the slight movement of the power supply body 3 during the front and rear positioning process, avoiding friction damage to the surface of the power supply body 3. The U-shaped seats 15 provide stable installation support for the positioning wheels 16, ensuring that the positioning wheels 16 rotate flexibly and have a stable structure.

[0029] The column 11 is fixedly connected to the middle of the inner top wall of the housing 2. The first spring 12 and the first guide post 17 are fixedly connected to both sides of the column 11. The other end of the first spring 12 is fixedly connected to the first moving plate 13. The other end of the first guide post 17 slides through the first moving plate 13 and is fixedly connected to the inner wall of the housing 2. When the first moving plate 13 moves towards the power supply body 3, the first spring 12 is compressed and generates a reverse elastic force. After the test is completed, the first moving plate 13 and the positioning wheel 16 can be driven to reset, which is convenient for removing the power supply body 3. The sliding cooperation between the first guide post 17 and the first moving plate 13 can limit the movement trajectory of the first moving plate 13, ensuring that it only moves left and right in the horizontal direction, avoiding vertical offset or tilting, and ensuring the positioning accuracy of the positioning wheel 16 on the power supply body 3.

[0030] The housing 2 has two second movable plates 19 slidably connected inside. Each of the two second movable plates 19 has a connecting rod 20 fixedly connected to its side that is close to each other. Each of the two connecting rods 20 has a positioning plate 21 fixedly connected to its end that is close to each other. The two positioning plates 21 are located on the front and rear sides of the power supply body 3 respectively. The positioning plate 21 has a large contact area with the power supply body 3, which can avoid damage to the power supply body 3 due to excessive local pressure, and at the same time improve the stability of the positioning in the front and rear directions.

[0031] The front and back of the column 11 are fixedly connected to the second spring 18 and the second guide post 26. The other end of the second spring 18 is fixedly connected to the second moving plate 19. The other end of the second guide post 26 slides through the second moving plate 19 and is fixedly connected to the inner wall of the housing 2. When the second moving plate 19 moves toward the power supply body 3, the second spring 18 is compressed and generates a reverse elastic force. After the test is completed, the second moving plate 19 and the positioning plate 21 can be driven to reset, which is convenient for removing the power supply body 3. The sliding cooperation between the second guide post 26 and the second moving plate 19 can limit the movement trajectory of the second moving plate 19, ensuring that it only moves back and forth in the horizontal direction, avoiding vertical offset or tilt, and ensuring the positioning accuracy of the positioning plate 21 for the power supply body 3.

[0032] Two second moving plates 19 are fixedly connected to L-shaped wedge plates 22 on their sides that are close to each other. Two second wedge plates 23 are slidably connected to both sides of the housing 2. The second wedge plates 23 correspond one-to-one with the L-shaped wedge plates 22, and the inclined surface of the L-shaped wedge plate 22 is in contact with the inclined surface of the second wedge plate 23. Three wedge plates 28 are fixedly connected to the sides of the two second wedge plates 23 that are far apart from each other. When the second wedge plate 23 moves left and right, its inclined surface can interact with the inclined surface of the L-shaped wedge plate 22, converting the force in the left and right direction into a force that drives the second moving plates 19 to move back and forth, thereby realizing the positioning action in the back and forth direction.

[0033] The outer surfaces of the two second wedge plates 23 are fixedly connected to moving blocks 25, and the outer surfaces of the two moving blocks 25 are fixedly connected to third springs 24. The other end of the third springs 24 is fixedly connected to the inner wall of the housing 2. The two side walls of the housing 2 are fixedly connected to third guide posts 27, and the other end of the third guide posts 27 slides through the moving blocks 25. When the second wedge plate 23 is moved by force, the third spring 24 is stretched. After testing, the second wedge plate 23 can be driven to reset. The third guide posts 27 restrict the movement direction of the moving blocks 25 and the second wedge plates 23, ensuring that they only move left and right in the horizontal direction, thus ensuring the stability of the wedge surface contact and the accuracy of the force transmission.

[0034] The pressing assembly includes two fourth wedge plates 29 and two fifth wedge plates 30 fixedly connected to the bottom surface of the lifting plate 10. The fourth wedge plates 29 correspond one-to-one with the first wedge plates 14, and the fifth wedge plates 30 correspond one-to-one with the third wedge plates 28. The fourth wedge plates 29 and the fifth wedge plates 30 move up and down synchronously with the lifting plate 10. Their inclined surfaces are adapted to the inclined surfaces of the first wedge plates 14 and the third wedge plates 28, respectively. The up-down movement is converted into a force that drives the first wedge plates 14 and the third wedge plates 28 to move left and right, thereby realizing the linkage positioning of the centering mechanism. No additional drive source is required, which simplifies the structure of the device.

[0035] An electric push rod 4 is installed on the top of the test chamber 1. The telescopic end of the electric push rod 4 slides through the upper surface of the test chamber 1 and is fixedly connected to the upper surface of the pressure cover 5. A temperature sensor 7 is installed inside the pressure cover 5. The electric push rod 4 provides stable power for the lifting and lowering of the pressure cover 5. Its telescopic stroke can be precisely controlled to ensure that the pressure cover 5 can smoothly press the power supply body 3, while avoiding excessive pressure that could damage the power supply body 3. The temperature sensor 7 is built into the pressure cover 5. When the pressure cover 5 presses the power supply body 3, it can monitor the temperature change of the power supply body 3 during operation at close range, ensuring the accuracy of temperature data monitoring.

[0036] A signal processing module 8 is installed on one side wall of the test chamber 1. The signal processing module 8 is connected to the conductive post 6 via wires. The signal processing module 8 and the temperature sensor 7 are electrically connected. A control module 9 is installed on one side of the test chamber 1. The control module 9 and the signal processing module 8 are electrically connected. The conductive post 6 collects the voltage and current signals of the power supply body 3 and transmits them to the signal processing module 8. The temperature signal collected by the temperature sensor 7 is synchronously transmitted to the signal processing module 8. The signal processing module 8 performs filtering, amplification, conversion and other processing on various signals and then transmits them to the control module 9. The control module 9 can display the test data in real time and control the start and stop of the electric push rod 4 according to preset parameters, so as to realize the automated control and data visualization of the test process.

[0037] Working principle When performing performance tests on the main body 3 of the energy storage power supply, the main body 3 without the top cover is first placed on the upper surface of the housing 2. Then, the electric push rod 4 is activated, and the extension end of the electric push rod 4 is extended. The electric push rod 4 drives the pressure cover 5 to move downward in the vertical direction. The pressure cover 5 simultaneously drives the lifting plate 10 and the fourth wedge plate 29 and the fifth wedge plate 30 on the bottom surface of the lifting plate 10 to move downward (during the test, the signal processing module 8 is always connected to the two conductive posts 6 through wires).

[0038] When the fourth wedge plate 29 moves downward until its inclined surface aligns with the inclined surface of the first wedge plate 14, as the lifting plate 10 continues to descend, the inclined surface of the fourth wedge plate 29 and the inclined surface of the first wedge plate 14 exert a squeezing force. This force pushes the first wedge plate 14 to move horizontally towards the power supply body 3. The first wedge plate 14 simultaneously drives the first moving plate 13, the U-shaped seat 15, and the positioning wheel 16 to move towards the power supply body 3. At this time, the first spring 12 is compressed and generates an elastic restoring force. When the two positioning wheels 16 move to close contact with both sides of the power supply body 3 and reach their maximum stroke, the power supply body 3 achieves centering in the left and right directions. Subsequently, the fourth wedge plate 29 continues to descend and moves completely to one side of the first wedge plate 14, no longer applying a horizontal force to the first wedge plate 14. The left and right positioning action is completed.

[0039] The lifting plate 10 continues to move downwards, causing the fifth wedge plate 30 to descend until its inclined surface contacts the inclined surface of the third wedge plate 28. As the fifth wedge plate 30 continues to descend, its inclined surface and the inclined surface of the third wedge plate 28 generate a squeezing force, pushing the third wedge plate 28 to move horizontally towards the middle of the housing 2. The third wedge plate 28 simultaneously drives the second wedge plate 23 and the moving block 25 to move in the same direction. At this time, the third spring 24 is stretched and generates an elastic restoring force. During the movement of the second wedge plate 23, its inclined surface interacts with the inclined surface of the L-shaped wedge plate 22, converting the horizontal force into a force that drives the L-shaped wedge plate 22 to move towards the power source 3. The L-shaped wedge plate 22 drives the second moving plate 19, connecting rod 20 and positioning plate 21 to move towards the power supply body 3. The second spring 18 is compressed. When the two positioning plates 21 move to close contact with the front and rear sides of the power supply body 3 and reach the maximum stroke, the power supply body 3 is centered in the front and rear direction (during the process of the positioning plate 21 pushing the power supply body 3 to move, the power supply body 3 and the positioning wheel 16 slide relative to each other, and the positioning wheel 16 rotates accordingly to avoid interfering with the movement of the power supply body 3). Then the fifth wedge plate 30 continues to move down and moves completely to one side of the third wedge plate 28, no longer applying horizontal force to the third wedge plate 28. The front and rear positioning action is completed.

[0040] The lifting plate 10 drives the pressure cover 5 to continue to descend, and the pressure cover 5 gradually presses against the upper surface of the power supply body 3 to achieve a seal on the power supply body 3. At this time, the two conductive posts 6 on the pressure cover 5 make precise contact with the positive and negative poles of the power supply body 3, respectively. The temperature sensor 7 is close to the power supply body 3 and begins to monitor the temperature. The conductive posts 6 collect the voltage and current signals of the power supply body 3, and the temperature sensor 7 collects the temperature signal. Both types of signals are transmitted to the signal processing module 8 for processing. The processed signals are transmitted to the control module 9. The control module 9 displays, stores or analyzes the test data to complete the performance test of the energy storage power supply.

[0041] After the test is completed, the telescopic end of the electric push rod 4 is retracted by the control module 9, which drives the pressure cover 5, the lifting plate 10, and the fourth wedge plate 29 and the fifth wedge plate 30 to reset upward. After the fourth wedge plate 29 and the fifth wedge plate 30 are reset, the first spring 12, the second spring 18, and the third spring 24 release their elastic reset forces, driving the first moving plate 13, the second moving plate 19, the second wedge plate 23, and other components to reset. The positioning wheel 16 and the positioning plate 21 are separated from the power supply body 3. At this time, the power supply body 3, which has been tested, can be directly removed, completing the entire test process.
