Two fixing plates are fixedly connected to the top of the base on both sides. A groove is formed on the top of the opposite surfaces of the two fixing plates, and the inner wall of each groove contacts the outer wall of a stop block. Electric telescopic rods are fixedly connected to both sides of the top of the opposite surfaces of the two fixing plates. The output ends of the four electric telescopic rods penetrate the fixing plates and extend into the grooves. One end of each electric telescopic rod extending into the groove is fixedly connected to one side of the surface of the stop block. A lifting device is provided at the top of the base.

[0004] Based on the above search results and existing technologies, the following findings were made:

[0005] In the current testing process for new energy batteries, the batteries need to be loaded and fixed. However, the loading and fixing operations of most batteries are usually divided into two separate steps, which makes the process cumbersome and inefficient, thereby reducing the testing efficiency of new energy batteries. Utility Model Content

[0006] To address the aforementioned technical problems, this utility model proposes a battery testing device for new energy vehicle repair. Through the setting of an automatic fixing mechanism, when the motor drives the fixing block and the placement plate into the box through the threaded rod, the extrusion rod extrudes the bending plate, causing the sliding rod and the extrusion plate to move. The two extrusion plates move closer to each other to fix the battery, thus realizing automatic battery fixing.

[0007] The technical solution to achieve the purpose of this utility model is as follows: a battery testing device for repairing new energy vehicles, including a box, two slide rails are fixedly connected to the bottom inner wall of the box, a sliding strip is slidably connected to each of the two slide rails, and a placement plate is fixedly connected to the top of the two sliding strips; and also includes:

[0008] An automatic fixing mechanism, which is located on the placement plate;

[0009] An automatic lifting mechanism is located on the housing;

[0010] The automatic fixing mechanism includes two mounting blocks fixedly connected to the top of the placement plate. Each mounting block is slidably connected to a sliding rod. An extrusion plate is fixedly connected to the end of each sliding rod that is close to each other, and a bending plate is fixedly connected to the end of each sliding rod that is far from each other. Extrusion rods are fixedly connected to both sides of the box body. Each extrusion rod is in contact with a bending plate. A motor is fixedly connected to the box body. A threaded rod is fixedly connected to the output end of the motor. A fixing block is screwed onto the threaded rod. The fixing block is fixedly connected to the bottom of the placement plate.

[0011] In some embodiments, a return spring is fitted onto each of the two sliding rods, and the two ends of the return spring are fixedly connected to the pressing plate and the mounting block, respectively.

[0012] In some embodiments, both extrusion plates are made of rubber.

[0013] In some embodiments, the automatic lifting mechanism includes a movable plate slidably connected to the housing, a fixed rack fixedly connected to the movable plate, a rotating shaft rotatably connected to the housing, a large gear fixedly connected to the rotating shaft, the large gear and the fixed rack being adapted to each other, a fixed rod fixedly connected to the inner wall of the housing, a sliding rack slidably connected to the fixed rod, and a small gear fixedly connected to one end of the rotating shaft, the sliding rack and the small gear meshing with each other.

[0014] In some embodiments, the fixed rod is provided with a telescopic spring, and the two ends of the telescopic spring are fixedly connected to the fixed rod and the sliding rack, respectively.

[0015] In some embodiments, a vertical rod is fixedly connected to the sliding rack, and a pressing block is fixedly connected to the placement plate, the pressing block being adapted to the vertical rod.

[0016] Compared with existing technologies, the significant advantages of this invention are:

[0017] Firstly, this utility model, through the setting of an automatic fixing mechanism, when the motor drives the fixing block and the placement plate into the box through the threaded rod, the extrusion rod extrudes the bending plate, causing the sliding rod and the extrusion plate to move. The two extrusion plates move closer to each other to fix the battery, thus realizing the automatic fixing of the battery.

[0018] Secondly, this utility model, through the setting of an automatic lifting mechanism, moves the placing plate, causing the squeezing block to move away from the vertical rod. This causes the telescopic spring to move the sliding rack outward, which in turn causes the small gear, rotating shaft, and large gear to rotate. The rotation of the large gear causes the fixed rack and the movable plate to move upward, thereby opening the movable plate. When the placing plate moves out of the box, the movable plate automatically closes, thus automatically closing the box and improving the safety of the tested battery.

[0019] This solves the problem that existing battery loading and fixing operations are usually divided into two separate steps, resulting in a cumbersome process and low efficiency. Attached Figure Description

[0028] The present invention will now be described in detail, and the technical solutions in the embodiments of the present invention will be clearly and completely described. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present invention.

[0029] This utility model provides an improved battery testing device for new energy vehicle repair. The technical solution of this utility model is as follows:

[0030] like Figures 1-5As shown, a battery testing device for new energy vehicle repair includes a housing 1. Two slide rails 12 are fixedly connected to the bottom inner wall of the housing 1. Sliding bars 13 are slidably connected to each of the two slide rails 12. A placement plate 14 is fixedly connected to the top of the two sliding bars 13. The device also includes an automatic fixing mechanism located on the placement plate 14 and an automatic lifting mechanism located on the housing 1. The automatic fixing mechanism includes two mounting blocks 2 fixedly connected to the top of the placement plate 14. Sliding rods 21 are slidably connected to each of the two mounting blocks 2. A pressing plate 22 is fixedly connected to the end of each sliding rod 21 that is close to each other, and a pressing plate 22 is fixedly connected to the end of each sliding rod 21 that is far from each other. A bending plate 24 is fixedly connected, and a pressing rod 25 is fixedly connected to both sides of the housing 1. The two pressing rods 25 are in contact with the two bending plates 24 respectively. A motor 15 is fixedly connected to the housing 1, and a threaded rod 16 is fixedly connected to the output end of the motor 15. A fixing block 17 is screwed onto the threaded rod 16, and the fixing block 17 is fixedly connected to the bottom of the placement plate 14. With the automatic fixing mechanism, when the motor 15 drives the fixing block 17 and the placement plate 14 into the housing 1 through the threaded rod 16, the pressing rod 25 presses the bending plate 24, causing the sliding rod 21 and the pressing plate 22 to move. The two pressing plates 22 move closer to each other to fix the battery, thus realizing the automatic fixing of the battery.

[0031] like Figure 3 As shown, in one embodiment, a return spring 23 is sleeved on each of the two sliding rods 21. The two ends of the return spring 23 are fixedly connected to the extrusion plate 22 and the mounting block 2, respectively. With the setting of the return spring 23, when the bending plate 24 moves away from the extrusion rod 25, the return spring 23 drives the sliding rod 21 and the extrusion rod 25 to return to their original positions.

[0032] like Figure 3 As shown, in one embodiment, both extrusion plates 22 are made of rubber; by setting the extrusion plates 22 to be made of rubber, the adhesion between the extrusion plates 22 and the battery is improved.

[0033] like Figure 4As shown, in one embodiment, the automatic lifting mechanism includes a movable plate 11 slidably connected to a housing 1, a fixed rack 36 fixedly connected to the movable plate 11, a rotating shaft 33 rotatably connected to the housing 1, a large gear 35 fixedly connected to the rotating shaft 33, the large gear 35 and the fixed rack 36 being adapted to each other, a fixed rod 3 fixedly connected to the inner wall of the housing 1, a sliding rack 31 slidably connected to the fixed rod 3, a small gear 34 fixedly connected to one end of the rotating shaft 33, the sliding rack 31 and the small gear 34 meshing, a telescopic spring 32 provided inside the fixed rod 3, the two ends of the telescopic spring 32 being fixedly connected to the fixed rod 3 and the sliding rack 31 respectively, and a fixed connection on the sliding rack 31 being... A vertical rod 37 is provided, and a pressing block 38 is fixedly connected to the placement plate 14. The pressing block 38 is adapted to the vertical rod 37. Through the setting of the automatic lifting mechanism, the placement plate 14 moves, causing the pressing block 38 to move away from the vertical rod 37. This causes the telescopic spring 32 to drive the sliding rack 31 to move outward. The movement of the sliding rack 31 drives the pinion 34, the rotating shaft 33, and the large gear 35 to rotate. The rotation of the large gear 35 drives the fixed rack 36 and the movable plate 11 to move upward, thereby opening the movable plate 11. When the placement plate 14 moves out of the box 1, the movable plate 11 automatically closes, realizing the automatic closing of the box 1 and improving the safety of the tested battery.

[0034] The specific working method is as follows: Motor 15 drives threaded rod 16 to rotate. The rotation of threaded rod 16 causes fixed block 17 and placement plate 14 to move outward. The movement of placement plate 14 causes mounting block 2, sliding rod 21 and bending plate 24 to move, so that bending plate 24 moves away from pressing rod 25. Since return spring 23 is in a stretched state, return spring 23 causes sliding rod 21 and pressing plate 22 to return to their original positions. The movement of placement plate 14 causes pressing block 38 to move, so that pressing block 38 moves away from vertical rod 37. Since telescopic spring 32 is in a compressed state, telescopic spring 32 causes sliding rack 31 to move outward. The movement of sliding rack 31 causes pinion 34, rotating shaft 33 and large gear 35 to rotate. The rotation of large gear 35 causes fixed rack 36 and movable plate 11 to move upward, thereby opening movable plate 11. Then placement plate 14 moves to... Outside the housing 1, the battery to be tested is placed on the placement plate 14. The motor 15 drives the threaded rod 16 to rotate in the opposite direction. The rotation of the threaded rod 16 drives the fixing block 17 and the placement plate 14 into the housing 1, causing the extrusion rod 25 to extrude the bending plate 24, which in turn moves the sliding rod 21 and the extrusion plate 22. The two extrusion plates 22 move closer to each other to fix the battery. The extrusion block 38 extrudes the vertical rod 37, which in turn moves the sliding rack 31 into the fixing rod 3, causing the movable plate 11 to close. Then the testing tool tests the battery. When the placement plate 14 moves out of the housing 1, it facilitates the feeding of the battery and automatically opens the movable plate 11. When the placement plate 14 moves into the housing 1, the movable plate 11 automatically closes, and the extrusion plate 22 automatically fixes the battery. This achieves automatic battery fixation and closes the housing 1, improving the safety of battery testing.
