[0001] The utility model relates to the technical field of vehicle-mounted batteries, in particular to a vehicle-mounted battery pack. Background Art

[0002] The battery pack is an independent and reliable power source. It is not affected by the AC power supply. When any accident occurs in the power plant or substation, or even when the AC power supply of the entire plant or station is cut off, it can still ensure that the electrical equipment in the DC system can work reliably and continuously. Now, battery packs are widely used in the automobile manufacturing industry.

[0003] During automobile manufacturing, a large number of battery packs are transported to automobile manufacturing plants so that the battery packs can be installed inside during manufacturing. Among them, a vehicle-mounted battery pack disclosed by patent number CN219759795U includes an isolation box, a battery pack body is arranged in the middle of the interior of the isolation box, a top cover is installed on the top of the isolation box, the top cover and the isolation box are connected by a fixing mechanism, a plurality of first springs are fixedly connected to the inner wall rectangular array of the isolation box, a plurality of second springs are fixedly connected to the bottom end surface rectangular array of the top cover, the outer side surface of the battery pack body abuts against the rubber pad, and a sealing mechanism is arranged between the isolation box and the top cover. The present application utilizes the cooperation of the first spring and the second spring to provide a shock absorbing effect to the battery pack body during vibration, thereby protecting the battery pack body. Since the first spring is arranged on the inner bottom wall of the isolation box and the surrounding side of the inner wall of the isolation box, it can have a multi-directional buffering and shock absorbing effect on the battery pack body.

[0004] In the prior art, shock absorption of the battery pack is achieved by arranging multiple groups of springs in the isolation box. However, during transportation, when the transport vehicle travels on an uneven road surface, the isolation box will be caused to shake. During the shaking, the springs on all sides will be squeezed. During the squeezing process, the springs will rebound. When rebounding, the spring will push the battery. At this time, the spring on the other side of the battery is pushed and squeezed again. After the squeezing, the spring rebounds again and pushes again, causing the battery to be in a state of continuous shaking. In the event of severe shaking, the battery may hit the inner wall of the isolation box, causing damage to the battery and affecting it. Utility Model Content

[0028] Please see attached picture Figure 1-Figure 5 As shown, a vehicle-mounted battery pack in the embodiment of the utility model includes a shock-absorbing box 1 and a battery pack body 3, and also includes: a clamping box 4 arranged in the shock-absorbing box 1; a first clamping assembly 5 and a second clamping assembly 6 arranged in the clamping box 4; the clamping box 4 is fixedly connected to the bottom of the shock-absorbing box 1; the first clamping assembly 5 includes a clamping screw 55; the clamping screw 55 is provided with two groups; the clamping screw 55 is rotatably connected to the side wall of the clamping box 4; a moving block 57 is threadedly connected to the clamping screw 55; the second clamping assembly 6 includes a clamping plate 61; the bottom of the clamping plate 61 is fixedly connected to the top of the moving block 57; a bidirectional screw 62 is rotatably connected to the middle of the clamping plate 61; the bidirectional screw 62 and the clamping screw 55 are driven to rotate; a slider 64 is threadedly connected to the bidirectional screw 62; the slider 64 is provided with two groups; the side wall of the slider 64 is fixedly connected to a fixing plate 63; the battery pack body 3 is placed in the middle of the clamping box 4;

[0029] During operation, shock absorption of the battery pack is achieved by arranging multiple groups of springs in the isolation box. However, during transportation, when the transport vehicle travels on an uneven road surface, the isolation box will be driven to shake. During shaking, the springs on all sides will be squeezed. During the squeezing process, the springs will rebound. When rebounding, the spring will push the battery. At this time, the spring on the other side of the battery is pushed and squeezed again. After squeezing, the spring rebounds again and pushes again, causing the battery to be in a state of continuous shaking. In the event of severe shaking, the battery may hit the inner wall of the isolation box, causing damage to the battery and affecting it. In order to prevent such incidents from happening, first, the battery pack body 3 is placed on the clamping box 4 in the shock absorbing box 1, and then the clamping screw 55 in the clamping box 4 is driven to rotate. Two groups of clamping screws 55 are arranged. When the clamping screw 55 is driven to rotate, the screw 55 can be driven The two groups of moving blocks 57 connected by the grooves move toward the battery pack body 3. During the movement, the battery pack body 3 is clamped and fixed by the clamping plate 61 in the second clamping assembly 6. After fixation, in order to prevent the battery pack body 3 from lateral movement, the fixing plate 63 on the clamping plate 61 can be used for secondary fixation. When fixing, the bidirectional screw rod 62 in the clamping plate 61 is driven to rotate. When the bidirectional screw rod 62 rotates, it can drive the two groups of sliders 64 to move in a mirror image, that is, move to the middle of the clamping plate 61 at the same time or move to both sides at the same time. When moving to the middle of the clamping plate 61, the side of the battery pack body 3 is clamped to avoid lateral shaking of the battery pack body 3 during shaking. The first clamping assembly 5 and the second clamping assembly 6 arranged in the clamping box 4 are used to effectively fix the battery pack to avoid strong shaking of the battery pack body 3 and damage.

[0030] like Figure 2As shown, the bottom of the clamping box 4 is fixedly connected to a driving shaft 51; the top of the driving shaft 51 is rotatably connected to a crown gear 52; the middle of the crown gear 52 is rotatably connected to a connecting shaft 53; the top of the connecting shaft 53 is fixedly connected to a connecting block 54; the end of the clamping screw 55 away from the clamping box 4 is rotatably connected to the side wall of the connecting block 54; the clamping screw 55 is fixedly connected to a transmission gear 56; the transmission gear 56 is meshed and connected with the crown gear 52;

[0031] During operation, when the battery pack body 3 is clamped, the driving shaft 51 drives the crown gear 52 to rotate, and the rotation will drive the transmission gear 56 to rotate. The transmission gear 56 is a bevel gear. When the transmission gear 56 rotates, it will drive the moving screw to rotate, thereby driving the moving block 57 and the clamping plate 61 to clamp the battery pack body 3.

[0032] like Figure 2 As shown, a clamping groove 41 is provided in the middle of the clamping box 4; the moving block 57 is arranged to penetrate the clamping groove 41; a telescopic plate 42 is fixedly connected to the middle of the clamping groove 41; and the side wall of the moving block 57 is fixedly connected to the telescopic plate 42;

[0033] During operation, the moving block 57 passes through the clamping groove 41, and a telescopic plate 42 is provided in the clamping groove 41. When the moving block 57 moves, the telescopic plate 42 is driven to move, and the clamping groove 41 is in a closed state to prevent the internal crown gear 52 and other transmission mechanisms from being exposed.

[0034] like Figure 5 As shown, the top of the shock absorbing box 1 is movably connected with a cover plate 2; the bottom of the cover plate 2 is fixedly connected with a shock absorbing damper 22; the shock absorbing damper 22 is provided with multiple groups; the bottom of the shock absorbing damper 22 is fixedly connected with a heat sink 24; the outside of the shock absorbing damper 22 at the bottom of the cover plate 2 is fixedly connected with a shock absorbing spring 23; the end of the shock absorbing spring 23 away from the cover plate 2 is fixedly connected to the heat sink 24;

[0035] During operation, after the battery pack body 3 is clamped, the staff installs the cover plate 2 on the top of the shock absorbing box 1. The bottom of the cover plate 2 is provided with a shock absorbing damper 22, a shock absorbing spring 23 and a heat sink 24. After the installation is completed, the bottom of the heat sink 24 abuts against the top of the battery pack body 3. After abutment, the top of the battery pack body 3 can be shock-absorbed by the shock absorbing spring 23 and the shock absorbing damper 22. The shock absorbing damper 22 can prevent the shock absorbing spring 23 from continuously rebounding.

[0036] like Figure 1 As shown, the four corners of the shock absorber box 1 are provided with bolt holes 11; the four corners of the cover plate 2 are rotatably connected with fixing bolts 21;

[0037] During operation, the cover plate 2 is mounted on the shock absorbing box 1 through the cooperation of the bolt holes 11 and the fixing bolts 21 .

[0038] like Figure 3 As shown, the side wall of the clamping plate 61 is fixedly connected to a driving motor 65; the bidirectional screw rod 62 is driven to rotate by the driving motor 65;

[0039] During operation, the bidirectional screw rod 62 can be driven to rotate by the driving motor 65 , thereby driving the fixing plate 63 to fix the battery pack body 3 .

[0040] like Figure 4 As shown, the side wall of the clamping box 4 is provided with a limiting groove 43; a limiting column 44 is slidably connected in the limiting groove 43; and one end of the limiting column 44 away from the limiting groove 43 is fixedly connected to the side wall of the moving block 57;

[0041] During operation, the limiting column 44 is slidably connected in the limiting groove 43, and the other end is fixedly connected to the side wall of the moving block 57, so as to prevent the moving block 57 from being offset and stuck during movement.

[0042] The working principle of the utility model is as follows: shock absorption of the battery pack is achieved by arranging multiple groups of springs in the isolation box. However, during transportation, when the transport vehicle travels on an uneven road surface, the isolation box will be driven to shake. During shaking, the springs on all sides will be squeezed. During the squeezing process, the springs will rebound. When rebounding, the spring will push the battery. At this time, the spring on the other side of the battery is pushed and squeezed again. After squeezing, the spring rebounds again and pushes again, so that the battery is in a state of continuous shaking. In case of severe shaking, the battery may hit the inner wall of the isolation box, causing damage to the battery and affecting it. In order to prevent such incidents from happening, first, the battery pack body 3 is placed on the clamping box 4 in the shock absorbing box 1, and then the clamping screw 55 in the clamping box 4 is driven to rotate. Two groups of clamping screws 55 are provided. When the clamping screw 55 is driven to rotate, The two groups of threaded moving blocks 57 are driven to move toward the battery pack body 3. During the movement, the battery pack body 3 is clamped and fixed by the clamping plate 61 in the second clamping assembly 6. After fixation, in order to prevent the battery pack body 3 from lateral movement, the fixing plate 63 on the clamping plate 61 can be used for secondary fixation. When fixing, the bidirectional screw rod 62 in the clamping plate 61 is driven to rotate. When the bidirectional screw rod 62 rotates, it can drive the two groups of sliders 64 to move in a mirror image, that is, move toward the middle of the clamping plate 61 at the same time or move to both sides at the same time. When moving toward the middle of the clamping plate 61, the side of the battery pack body 3 is clamped to avoid lateral shaking of the battery pack body 3 during shaking. The battery pack is effectively fixed by the first clamping assembly 5 and the second clamping assembly 6 arranged in the clamping box 4 to avoid damage to the battery pack body 3 caused by strong shaking.

[0043] The above is a detailed description of an embodiment of the utility model, but the content is only a preferred embodiment of the utility model and cannot be considered to limit the scope of implementation of the utility model. All equivalent changes and improvements made within the scope of application of the utility model should still fall within the scope of the patent coverage of the utility model.
