[0032] ​​​​​The auxiliary assembly 9 comprises a movable piece 20 which is provided with two and is slidably connected with the front and rear edges of the platform 5, and the movable piece 20 is fixedly connected with a first movable sleeve 18 on the surface, the platform 5 is provided with a support 16 on the outside, the front and rear ends of the support 16 are located inside the two first movable sleeves 18 respectively, the top of the support 16 is slidably connected with a second movable sleeve 22, a guide piece 21 is fixedly connected with the surface of one side wall of the second movable sleeve 22, an annular piece 27 is slidably connected with the surface of the guide piece 21, a reset spring 28 is fixedly connected between the bottom of the guide piece 21 and the annular piece 27, a horizontal plate 24 is fixedly connected with the surface of one side wall of the annular piece 27, and a sliding groove is formed in the surface of the horizontal plate 24 and a limiting sleeve 25 is slidably connected inside the sliding groove, and the limiting sleeve 25 is provided with two and is screwed with a fastening bolt 26 on the surface of the outer wall.

[0033] As shown in Figures 1-4 , the top of the second movable sleeve 22 is fixedly connected with a mounting piece 23 through a connecting piece, a fixed bolt is screwed with the surface of one side wall of the mounting piece 23, and a clamping plate is rotatably connected with the end of the fixed bolt and is slidably connected between the mounting piece 23.

[0034] When checking the power battery pack, a multimeter is generally used, and the staff places the multimeter at a suitable position and holds two probes to check the total voltage of the battery pack and the single cell voltage of each module. Since the power battery pack generally has a large number of battery cells, the staff is easily very tired after overall detection, and it is inconvenient to observe the information on the multimeter during the process. In the device, the user places two probes into the limiting sleeve 25 and locks them with the fastening bolt 26, then places the multimeter into the mounting piece 23 and fixes it with the fixed bolt, and then moves the two probes to the positive and negative electrodes of the single cell and presses down the annular piece 27 when checking the battery module. Since the reset spring 28 is arranged at the lower side of the annular piece 27, it can move downward under stress. Since the positive and negative electrodes of each single cell are consistent, the distance between the probes does not need to be adjusted again during the subsequent detection process after the first adjustment.

[0036] By inserting the latch 19 into the insertion hole 17 of a suitable height, the distance between the top of the support 16 and the surface of the platform 5 can be changed, so as to check the power battery pack of different sizes.

[0037] As shown in Figures 1-4 The platform 5 is rotationally connected with a plurality of equidistantly arranged roller shafts 6. One end of the first double-headed screw 2 extends to the outside of the base 1 and is fixedly connected with the output end of the driving motor. The driving motor is fixedly connected with the base 1.

[0038] The current power battery pack detection device does not require workers to place heavy equipment at a suitable height and fix it. In the device, the platform 5 is at a lower position in the normal state, which facilitates workers to lift the power battery pack thereon. Since a plurality of groups of roller shafts 6 are arranged on the surface of the platform 5, the power battery pack is very labor-saving to be placed thereon and taken therefrom. Then, the position of the sliding block 13 on the guide rail 12 is adjusted and locked by the locking bolt 14. Then, the second double-headed screw 10 is rotated to allow the left and right limiting members 15 to approach the power battery pack and fix the power battery pack in the middle. Finally, the driving motor is started to drive the first double-headed screw 2 to rotate, so that the two groups of sliding seats 3 approach each other through the connecting rods 4 to lift the platform 5, so that the platform 5 is at a height convenient for workers to check. The structure design can stably fix power battery packs of different sizes and is convenient for workers to take and place.

[0039] As shown in Figures 1-4 The platform 5 is provided with a limiting assembly 7. The limiting assembly 7 comprises a second double-headed screw 10 rotationally connected with the bottom of the platform 5. The surface of the second double-headed screw 10 is threadedly connected with a threaded sleeve 11 on the left and right sides. The top of the platform 5 is provided with a through slot 8 on the two side edges. The top of the two threaded sleeves 11 extends to the upper side of the platform 5 through the through slots 8 on the two sides and is fixedly connected with a guide rail 12.

[0040] The position of the limiting member 15 can be adjusted by the sliding block 13, so that the four limiting members 15 can limit the four corners of the power battery pack. The two groups of guide rails 12 can be moved towards the center by rotating the second double-headed screw 10, so that the limiting members 15 limit the power battery pack in the middle.

[0041] As shown in Figures 1-4 The guide rail 12 is slidingly connected with a sliding block 13 on the front and rear sides. The top of the sliding block 13 is threadedly connected with a locking bolt 14. The side wall of the sliding block 13 towards the roller shaft 6 is fixedly connected with a limiting member 15.

[0042] The sliding block 13 can be fixed at a suitable position on the guide rail 12 by the locking bolt 14, and the limiting member 15 can limit the edge corners of the power battery pack.

[0043] As shown in Figures 1-4 One end of the second double-headed screw 10 is fixedly connected with a rotating disc. The bottom of the base 1 is fixedly connected with a support leg on the two sides in front and back symmetry. The bottom of the support leg is bonded with a shock pad.

[0044] The second double screw rod 10 is conveniently rotated by the rotating disc, and the structure is kept stable and not easy to shake by setting the supporting legs with damping pads.

[0045] The working principle of the vehicle-mounted battery inspection device is as follows:

[0046] First step: when checking the power battery pack, a multimeter is generally used, and a worker places the multimeter at a suitable position and holds two probes to check the total voltage of the battery pack and the single voltage of each module. Since the power battery pack generally has a large number of battery monomers, the worker is very tired after overall detection, and it is inconvenient to observe the information on the multimeter during the process. In the device, the user places two probes into the limiting sleeve 25 and locks them with the fastening bolt 26, then places the multimeter into the mounting piece 23 and fixes it with the fixing bolt, and then moves the two probes to the positive and negative electrodes of the single battery and presses the annular piece 27. The lower side of the annular piece 27 can move downward under stress because of the reset spring 28. Since the positive and negative electrodes of each single battery are consistent, the distance between the probes does not need to be adjusted during the subsequent detection process after the first adjustment. During detection, the user only needs to hold the horizontal plate 24 and slide it forward and backward or move it left and right to the specified position. This process does not require two hands, and the multimeter is always in the appropriate position, which is convenient for observation. The structure design is humanized and can improve efficiency.

[0047] Second step: the current power battery pack detection device does not use workers to place heavy equipment at a suitable height and fix it. In the device, the platform 5 is at a low position under normal conditions, which is convenient for workers to lift the power battery pack onto it. Since a plurality of roller shafts 6 are arranged on the surface, it is very labor-saving to place and take the power battery pack. Then, the position of the sliding block 13 on the guide rail 12 is adjusted and locked with the locking bolt 14. Then, the second double screw rod 10 is rotated to make the limiting pieces 15 on the left and right sides close to the power battery pack and fix it in the middle. Finally, the first double screw rod 2 is rotated by starting the driving motor, so that the two groups of sliding seats 3 close to each other are lifted by the connecting rods 4 to make the platform 5 at a height convenient for workers to check. The structure design can stably fix power battery packs of different sizes and is convenient for workers to take and place.
