Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0030] Specific examples are given below.

[0031] See also Figure 1-8 The present invention provides a battery capacity estimation device, comprising a mounting frame 1, on which a first servo motor 2 is mounted; a threaded rod 3 is connected to an output shaft of the first servo motor 2; both ends of the threaded rod 3 are rotatably connected to the mounting frame 1; a driving block 4 is threadedly connected to the threaded rod 3; a first detection plate 6 is mounted on the driving block 4; a fixing component is mounted on the first detection plate 6; a support frame 71 is mounted on one end of the mounting frame 1 away from the first servo motor 2; an adjustment component is mounted on the support frame 71; a detection component is connected to the adjustment component;

[0032] During operation, the battery pack is placed on the first detection plate 6, and the first servo motor 2 drives the threaded rod 3 to rotate. The threaded rod 3 drives the driving block 4 threadedly connected thereto to move horizontally, so that the driving block 4 drives the battery pack on the first detection plate 6 to move toward the detection component. The driving block 4 slides on the sliding guide rods 5 on both sides at the same time. When the driving block 4 drives the battery pack on the first detection plate 6 to move, the fixed component clamping plate 75 on the first detection plate 6 clamps the two sides of the battery pack as the driving block 4 moves, so that the motor group moves during capacity detection. When the first detection plate 6 moves below the mounting plate 141, the positive and negative electrodes on the battery pack are aligned with the electrode connector 145, and then the second screw 131 on the adjusting component drives the battery tester body 142 on the mounting plate 141 connected thereto to move downward, and the battery tester body 1 42 is connected to the positive and negative electrodes of the battery through the electrode connector 145 connected to the positive electrode connecting line 143 and the negative electrode connecting line 144, and then the battery tester body 142 measures the battery voltage, current, internal resistance and other parameters of the battery pack, and then detects the capacity of the battery; through the drive of the first servo motor 2, the full automation process from placement to detection of the battery pack is realized, which not only reduces manual intervention, but also improves the detection efficiency and accuracy, and solves the problem that when the battery pack is tested for capacity, it is partially necessary to manually fix the positive and negative electrodes on the battery, and manual fixing of the positive and negative electrodes on the battery may cause short circuit, electric shock and other safety hazards due to improper operation. Compared with the traditional method of manually fixing the positive and negative electrodes of the battery, there are safety hazards such as short circuit and electric shock. The device automatically clamps the two sides of the battery pack through the fixing components and keeps it stable during movement, effectively reducing these risks.

The first screw 72 rotates and drives the sliding rod 77 threadedly connected thereto to move toward one side of the battery pack. The two sliding rods 77 drive the clamping plate 75 to clamp the two sides of the battery pack. The anti-skid pad 76 on the clamping plate 75 better fixes the two sides of the battery pack, and then fixes the battery pack to reduce its movement during detection. When the detection is completed, the first servo motor 2 drives the first detection plate 6 on the driving block 4 to reset through the threaded rod 3. At the same time, the first gear 73 meshes with the first rack 9 again, and then drives the first gear 73 to reverse so that the first gear 73 drives the clamping plate 75 connected to the first screw 72 to disengage from the two sides of the battery pack, which is convenient for subsequent testing of the battery pack; through the cooperation of the servo motor and the threaded rod 3, the automatic clamping and release of the battery pack is realized, and the detection efficiency is improved; the threaded connection and the anti-skid pad 76 design ensure the stability of the battery pack during the detection process, and reduce the impact of movement on the capacity detection of the battery pack.

The transmission structure of the worm 123 and the worm wheel 124 ensures the stability and accuracy of the movement, improves the detection efficiency, and then the sliding connecting rod 133 drives the mounting plate 141 to move up and down, and the sliding connecting rod 133 slides on the second sliding rods 132 on both sides thereof at the same time, and the mounting plate 141 drives the second sliding rods 132 connected thereto to move up and down. The battery tester body 142 moves downward, so that after the first test plate 6 is aligned with the electrode connector 145 on the insulating rod 17, the positive connecting line 143 and the negative connecting line 144 on the insulating rod 17 are overlapped with the positive and negative electrodes of the battery pack, so that the battery tester body 142 detects the capacity of the battery pack through the positive connecting line 143 and the negative connecting line 144; driven by the second servo motor 121, the entire detection process is automated, reducing the steps and time of manual operation, and automated operation reduces the chance of direct manual contact with the battery pack, further reducing safety risks.

[0036] like Figure 5As shown, the electrode connector 145 is connected to an insulating rod 17; a spiral block 16 is installed on the insulating rod 17; two third screws 15 are rotatably connected to the mounting plate 141; the spiral block 16 is threadedly connected to the third screw 15; when working, the third screw 15 is rotated, and the third screw 15 rotates on the mounting plate 141, driving the spiral block 16 threadedly connected thereto to move, and the spiral block 16 drives the electrode connector 145 on the insulating rod 17 to move, and the distance between the electrode connectors 145 is adjusted by rotating the two third screws 15, so as to adapt to the different horizontal positions of the positive and negative poles on the battery pack; by rotating the third screw 15, the position of the electrode connector 145 can be easily adjusted. This adjustment method is not only accurate, but also very flexible, and can quickly adapt to the horizontal positions of the positive and negative poles of different battery packs.

[0038] like Figure 1 As shown, a mounting rod 18 is installed on the mounting frame 1; a display screen 19 is installed on the mounting rod 18; four moving wheels 20 are installed at the bottom of the mounting frame 1; the display screen 19 is electrically connected to the battery tester body 142.

[0039] Working principle: When working, the battery pack is placed on the first detection plate 6, and the first servo motor 2 drives the threaded rod 3 to rotate. The threaded rod 3 drives the driving block 4 threadedly connected thereto to move horizontally, so that the driving block 4 drives the battery pack on the first detection plate 6 to move toward the detection component. The driving block 4 slides on the sliding guide rods 5 on both sides at the same time. When the driving block 4 drives the battery pack on the first detection plate 6 to move, the fixed component clamping plate 75 on the first detection plate 6 clamps the two sides of the battery pack as the driving block 4 moves, so that the motor group moves when performing capacity detection. When the first detection plate 6 moves below the mounting plate 141, the positive and negative electrodes on the battery pack are aligned with the electrode connector 145, and then the adjustment group The second screw 131 on the component drives the battery tester body 142 on the mounting plate 141 connected thereto to move downward, and the battery tester body 142 is connected to the positive and negative electrodes of the battery through the electrode connector 145 connected to the positive electrode connecting line 143 and the negative electrode connecting line 144, and then the battery tester body 142 measures the battery voltage, current, internal resistance and other parameters of the battery pack, and then detects the capacity of the battery; through the drive of the first servo motor 2, a fully automated process from placement to detection of the battery pack is realized, which not only reduces manual intervention, but also improves detection efficiency and accuracy, and solves the problem that when the battery pack is tested for capacity, some of the positive and negative electrodes need to be manually fixed on the battery, and manual fixing of the positive and negative electrodes on the battery may be due to operation Improper fixing of the positive and negative poles of the battery may lead to safety hazards such as short circuit and electric shock. Compared with the traditional method of manually fixing the positive and negative poles of the battery, there are safety hazards such as short circuit and electric shock. The device automatically clamps the two sides of the battery pack through the fixing assembly and maintains stability during movement, which effectively reduces these risks. When working, the first servo motor 2 drives the drive block 4 to move horizontally through the threaded rod 3, so that the drive block 4 drives the battery pack on the first detection plate 6 to move toward the detection assembly. When the first detection plate 6 moves, it drives the first gear 73 connected to the first screw rods 72 on both sides to rotate on the first rack 9 meshing with it, and then the first gear 73 drives the first screw 72 to rotate on the support frame 71, and the rotation of the first screw 72 drives the sliding The rod 77 moves to one side of the battery pack, and the two sliding rods 77 drive the clamping plate 75 to clamp the two sides of the battery pack. The anti-skid pads 76 on the clamping plate 75 better fix the two sides of the battery pack, and then fix the battery pack to reduce its movement during detection. When the detection is completed, the first servo motor 2 drives the first detection plate 6 on the driving block 4 to reset through the threaded rod 3.
