[0020] 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. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0021] Reference Figure 1-5A power battery thermal management test bench includes a test bench 1, a test chamber 2 with a front opening fixedly installed on the upper surface of the test bench 1, a cover plate 3 covering the front of the test chamber 2, and a heating plate, a temperature sensor, a humidity sensor, a humidifier and a dehumidifier installed inside the test bench 1, so as to control the temperature and humidity inside the test bench 1, and thus to conduct comprehensive performance tests on the power battery pack under various environments.

[0022] A support plate is fixedly connected to the top wall of the test chamber 2. A threaded rod 5 is rotatably installed between the support plate and the test chamber 2. A threaded plate 6 is threadedly connected to the outer surface of the threaded rod 5. First L-shaped plates 7 are fixedly connected to both sides of the threaded plate 6. Connecting posts 20 are fixedly connected to the front of the two first L-shaped plates 7. The other end of the connecting posts 20 is fixedly connected to the cover plate 3. A support plate 18 for supporting the power battery pack is fixedly connected to the bottom surface of the threaded plate 6. A guide plate 19 is fixedly connected to the bottom wall of the test chamber 2, and the guide plate 19 is slidably connected inside the support plate 18. The test chamber 2 is equipped with a motor 4. The output end of the motor 4 is fixedly connected to one end of the threaded rod 5. When the motor 4 is controlled to rotate in the forward direction, the motor 4 can drive the threaded rod 5 to rotate in the forward direction. The forward rotation of the threaded rod 5 can drive the threaded plate 6 to move forward along the threaded rod 5. When the motor 4 is controlled to rotate in the reverse direction, the motor 4 can drive the threaded rod 5 to rotate in the reverse direction. The reverse rotation of the threaded rod 5 can drive the threaded plate 6 to move backward along the threaded rod 5. The movement of the threaded plate 6 can drive the bearing plate 18 and the cover plate 3 to move accordingly, thereby realizing the automatic loading and unloading of the power battery pack.

[0023] A clamping mechanism for fixing the power battery pack is provided above the support plate 18. The clamping mechanism includes two U-shaped plates 10. The bottom surfaces of the two U-shaped plates 10 are fixedly connected to a second L-shaped plate 12. The sides of the two second L-shaped plates 12 that are close to each other are fixedly connected to a second support plate 13. The sides of the two second support plates 13 that are close to each other are fixedly connected to a spring 15. The ends of the two springs 15 that are close to each other are fixedly connected to a third support plate 14. The two third support plates 14 are fixedly connected inside the test chamber 2. The movement of the U-shaped plates 10 can drive the second L-shaped plates 12 and the second support plates 13 to move accordingly. When the U-shaped plates 10 move outward, they can stretch the springs 15.

[0024] The two second support plates 13 are fixedly connected to guide posts 16 on their sides that are close to each other, and the other end of the guide posts 16 slides through the third support plate 14. By setting the guide posts 16, the U-shaped plate 10 and the second L-shaped plate 12 can be prevented from deviating from their direction during movement.

[0025] Two first support plates 9 are fixedly connected to both sides of the test bench 1, and a U-shaped plate 10 is slidably connected between the two first support plates 9. A clamping plate 17 is fixedly connected to the side of the two U-shaped plates 10 that is close to each other. The upper and lower surfaces of the U-shaped plates 10 are provided with protruding strips, and the interior of the first support plate 9 is provided with a sliding groove that matches the protruding strip.

[0026] The interior of each of the two U-shaped plates 10 is fixedly connected with a second wedge plate 11. The front of each of the two first L-shaped plates 7 is fixedly connected with a first wedge plate 8 that is adapted to the second wedge plate 11. The interior of the test chamber 2 is fixedly connected with two T-shaped baffles 21 for blocking the power battery pack. During the test of the power battery pack, the inclined surface of the first wedge plate 8 is in contact with the inclined surface of the second wedge plate 11. At this time, the first wedge plate 8 moves forward, which can drive the second wedge plate 11 to move outward.

[0027] When testing the power battery pack, the power battery pack is first placed on the support plate 18. Then, the motor 4 is started, causing the threaded rod 5 to rotate in the opposite direction. The reverse rotation of the threaded rod 5 can move the threaded plate 6, the support plate 18, the first wedge plate 8, the cover plate 3, and the power battery pack into the test chamber 2. When the power battery pack on the support plate 18 moves to contact the T-shaped baffle 21, the support plate 18 continues to move inward, which can drive the first wedge plate 8 to move inward. At this time, the power battery pack will not move with it. During the inward movement of the first wedge plate 8, under the action of the spring 15, the second wedge plate 11 will move inward, always sticking to the first wedge plate 8. The inward movement of the second wedge plate 11 can drive the U-shaped plate 10 and the second L-shaped plate 12 to move inward. When the support plate 18 and the first wedge plate 8 move inward to the maximum extent, the two clamping plates 17 will clamp the power battery pack, and the cover plate 3 will cover the front of the test chamber 2, blocking the opening of the test chamber 2. At this time, the power battery pack can be tested.

[0028] After the test is completed, start motor 4, which drives threaded rod 5 to rotate forward. The forward rotation of threaded rod 5 can drive threaded plate 6, bearing plate 18, cover plate 3 and first wedge plate 8 to move outward. The outward movement of first wedge plate 8 can squeeze second wedge plate 11 to move outward. The outward movement of second wedge plate 11 can drive clamping plate 17 to move outward and stretch spring 15, thereby releasing the fixation of power battery pack. Then, the bearing plate 18 and first wedge plate 8 continue to move outward, which can drive power battery pack to move outward, thereby automatically removing power battery pack.

[0029] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
