Description

Technical Field

[0001] This utility model relates to the field of battery installation technology, specifically a mounting bracket for energy storage batteries in new energy vehicles. Background Technology

[0002] New energy vehicle energy storage batteries are energy storage devices that mainly use lithium-ion batteries (such as ternary lithium and lithium iron phosphate). They store and release electrical energy through chemical reactions to provide power for vehicles. At the same time, they need to take into account high energy density, long cycle life and safety and stability, and are one of the core components of new energy vehicles.

[0003] When installing energy storage batteries for new energy vehicles, disconnect the vehicle's low-voltage power supply, wear insulated gloves and other protective equipment, verify the battery model and parameters to ensure they match the vehicle, and check the battery's appearance for any abnormalities such as bumps or electrolyte leaks. Place the battery pack stably on the mounting bracket and secure it with bolts to the specified torque. Connect the high-voltage wiring harness, low-voltage control line, and BMS communication line in sequence, using buckles or cable ties to secure the lines and reduce shaking. Connect the low-voltage power supply, use a diagnostic tool to test the battery voltage, temperature data, and communication status of each interface, perform insulation resistance testing and charge / discharge trial runs, and input the battery information into the vehicle management system to complete the installation.

[0004] Existing mounting brackets for new energy vehicle energy storage batteries are too fixed and cannot accommodate different types of energy storage batteries. Therefore, a new mounting bracket for new energy vehicle energy storage batteries is proposed to address this issue. Utility Model Content

[0005] In order to overcome the shortcomings of the prior art, at least one technical problem raised in the background art is solved.

[0006] The technical solution adopted by this utility model to solve its technical problem is as follows: A new energy vehicle energy storage battery mounting bracket, comprising a bracket; a battery box fixedly connected to the top of the bracket; a cover plate installed on the top of the battery box; a sliding groove formed at the bottom of the cover plate; a stepper motor fixedly connected to the top of the cover plate; a cross connecting rod fixedly connected to the output end of the stepper motor; multiple transmission rods rotatably connected to the end of the cross connecting rod; a sliding block rotatably connected to the end of the transmission rod; a heat dissipation copper pipe slidably connected to the sliding block in the middle of the sliding groove; and a fixing block fixedly connected to the bottom of the sliding block. The stepper motor's rotation drives the fixing blocks to clamp the battery around its perimeter, allowing multiple fixing blocks to move synchronously, ensuring uniform force distribution on the battery within the battery box. Simultaneously, the sliding of the sliding blocks in the sliding groove can fix batteries of different specifications, increasing the versatility of the fixing blocks. This fixation ensures the battery remains in a fixed position within the battery box, reducing the risk of short circuits caused by friction or collision between the battery and the cover plate or other components due to vehicle movement.

[0007] Preferably, the bracket has a sandwich layer in the middle; a heat dissipation copper pipe is fixedly connected to the middle of the bracket; a heat-conducting sheet is fixedly connected to the surface of the bracket; the heat-conducting sheet and the heat dissipation copper pipe are in contact; cooling the battery through the heat dissipation copper pipe can reduce the occurrence of accidents such as smoke, fire, and explosion caused by excessive battery temperature, increase battery life, reduce battery capacity decay, and at the same time, controlling the battery temperature within a specified range can increase the stability of battery performance and increase charging and discharging efficiency.

[0008] Preferably, a heat dissipation rib is fixed to the bottom of the heat dissipation copper pipe; the heat dissipation rib penetrates the bottom of the bracket; the heat dissipation rib transfers the heat of the heat dissipation copper pipe to the outside air, which can increase the heat dissipation area and increase the heat conduction efficiency. The heat dissipation rib absorbs the heat of the heat dissipation copper pipe, which can reduce the surface temperature of the heat dissipation copper pipe and reduce the cracking of the solder joint or the deformation of the pipeline caused by thermal expansion and contraction.

[0009] Preferably, the battery housing has multiple ventilation openings on its surface; a filter screen is fixed to the inner side wall of the bracket; the filter screen and the ventilation openings are arranged correspondingly; by designing multiple ventilation openings, heat dissipation channels can be increased, the heat dissipation of the battery can be increased, and the service life of the battery and equipment can be extended. The filter screen can intercept external dust, impurities, etc., to reduce the entry of dust and impurities into the battery housing and contaminate the battery, and reduce the risk of decreased heat dissipation efficiency or battery failure caused by dust accumulation.

[0010] Preferably, a set of bases is installed at the bottom of the bracket; a slot is opened in the middle of the base; multiple limiting posts are fixed in the middle of the slot; by installing the bases, the direct contact between the bracket and the ground can be reduced, the surface quality of the bottom of the bracket can be increased, and the multiple limiting posts can separate the handling tools to form a balanced force point, so that the bracket is subjected to uniform force during handling, reducing the deformation or damage of the bracket caused by local overload. At the same time, the limiting posts reduce the sliding of the handling tools in the middle of the slot, which can cause the bracket to tilt and slip.

[0011] Preferably, a sealing gasket is fixed to the surface of the bracket; the sealing gasket is set on the outside of the battery box; by filling the gaps with the sealing gasket, rainwater, mud, dust and other substances can be reduced from entering the battery box when the vehicle is in motion, reducing short circuits in the battery cells or corrosion of metal parts. At the same time, the elastic material of the sealing gasket can absorb road bumps, motor vibrations and other substances transmitted to the bracket surface, reducing the risk of fatigue cracking at the bracket bolt holes.

[0012] The advantages of this utility model are:

[0013] 1. The new energy vehicle energy storage battery mounting bracket of this utility model uses a stepper motor to rotate and drive the fixing blocks to clamp the battery around its perimeter, which can make multiple fixing blocks move synchronously, so that the battery is subjected to uniform force in the battery box. At the same time, the sliding block in the sliding groove can fix batteries of different specifications, increasing the versatility of fixing blocks. Fixing the battery can keep the battery in a fixed position in the battery box, reducing the shaking caused by the vehicle during driving, which may cause the battery to rub or collide with the cover or other parts, resulting in damage to the insulation layer and short circuit.

[0014] 2. The new energy vehicle energy storage battery mounting bracket described in this utility model can reduce the occurrence of accidents such as smoke, fire, and explosion caused by excessive battery temperature by cooling the battery through heat dissipation copper pipes, thereby increasing battery life and reducing battery capacity decay. At the same time, controlling the battery temperature within a specified range can increase the stability of battery performance and increase charging and discharging efficiency.

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.

[0024] like Figures 1 to 5 As shown in the figure, a new energy vehicle energy storage battery mounting bracket according to an embodiment of the present invention includes a bracket 1; a battery box 11 is fixedly connected to the top of the bracket 1; a cover plate 12 is installed on the top of the battery box 11; a sliding groove 17 is formed at the bottom of the cover plate 12; a stepper motor 13 is fixedly connected to the top of the cover plate 12; a cross connecting rod 14 is fixedly connected to the output end of the stepper motor 13; a plurality of transmission rods 15 are rotatably connected to the end of the cross connecting rod 14; a sliding block 16 is rotatably connected to the end of the transmission rod 15; the sliding block 16 is slidably connected in the middle of the sliding groove 17; a fixing block 18 is fixedly connected to the bottom of the sliding block 16; during operation, the cover plate 12 is opened, the battery is placed on the surface of the bracket 1, and then the cover plate is closed. 12. Then, control the stepper motor 13 to rotate, and its output end drives multiple transmission rods 15 to rotate, so that the sliding block 16 slides in the middle of the slide groove 17, thereby driving the fixing block 18 to contact the battery surface for clamping. By rotating the stepper motor 13 to drive the fixing block 18 to clamp the battery around, multiple fixing blocks 18 can move synchronously, so that the battery is evenly stressed in the battery box 11. At the same time, the sliding of the sliding block 16 in the slide groove 17 can fix batteries of different specifications, increasing the versatility of fixing the fixing block 18. Fixing the battery can keep the battery in a fixed position in the battery box 11, reducing the shaking caused by the vehicle during driving, which may cause the battery to rub or collide with the cover plate 12 or other parts, resulting in damage to the insulation layer and causing a short circuit.

[0025] like Figures 4 to 5 As shown, the bracket 1 has a sandwich layer in the middle; a heat dissipation copper pipe 2 is fixedly connected to the middle of the bracket 1; a heat-conducting sheet 21 is fixedly connected to the surface of the bracket 1; the heat-conducting sheet 21 and the heat dissipation copper pipe 2 are in contact; during operation, the heat generated by the battery is transferred to the surface of the heat-conducting sheet 21, and cooling gas is injected into one end of the heat dissipation copper pipe 2. The gas is discharged from the other end of the heat dissipation copper pipe 2. When the gas passes through the heat dissipation copper pipe 2, it carries away the heat from the surface of the heat-conducting sheet 21, thereby cooling the battery. Cooling the battery through the heat dissipation copper pipe 2 can reduce the occurrence of accidents such as smoke, fire, and explosion caused by excessive battery temperature, increase battery life, reduce battery capacity decay, and at the same time, controlling the battery temperature within a specified range can increase the stability of battery performance and increase charging and discharging efficiency.

[0026] like Figure 2 As shown, a heat dissipation rib 3 is fixedly connected to the bottom of the heat dissipation copper pipe 2; the heat dissipation rib 3 penetrates the bottom of the bracket 1; during operation, the heat dissipation rib 3 transfers the heat on the surface of the heat dissipation copper pipe 2 to the outside air for heat dissipation; by transferring the heat of the heat dissipation copper pipe 2 to the outside air through the heat dissipation rib 3, the heat dissipation area can be increased and the heat conduction efficiency can be increased. The heat dissipation rib 3 absorbs the heat of the heat dissipation copper pipe 2, which can reduce the surface temperature of the heat dissipation copper pipe 2 and reduce the cracking of the solder joint or the deformation of the pipeline caused by thermal expansion and contraction.

[0027] like Figure 1 , Figure 2 and Figure 5 As shown, the battery housing 11 has multiple ventilation openings 4 on its surface; a filter screen 41 is fixed to the inner wall of the bracket 1; the filter screen 41 and the ventilation openings 4 are correspondingly arranged; during operation, the heat generated by the battery is discharged through the multiple ventilation openings 4, and the filter screen 41 intercepts impurities and dust in the outside air from entering the battery housing 11. By designing multiple ventilation openings 4, heat dissipation channels can be increased, the discharge of heat from the battery can be increased, and the service life of the battery and equipment can be extended. The filter screen 41 can intercept external dust and impurities, reducing the entry of them into the battery housing 11 and contaminating the battery, and reducing the risk of decreased heat dissipation efficiency or battery failure due to dust accumulation.

[0028] like Figures 1 to 2 As shown, a set of bases 5 are installed at the bottom of the bracket 1; a slot 51 is opened in the middle of the base 5; multiple limiting posts 52 are fixedly connected in the middle of the slot 51; during operation, multiple tools such as ropes are used to lift the bracket 1 as a whole through the set of slots 51 for transportation. By installing the bases 5, the direct contact between the bracket 1 and the ground can be reduced, and the surface quality of the bottom of the bracket 1 can be increased. At the same time, the multiple limiting posts 52 separate the transportation tools to form a balanced force point, so that the bracket 1 is subjected to uniform force during transportation, reducing the deformation or damage of the bracket 1 caused by local overload. At the same time, the limiting posts 52 reduce the sliding of the transportation tools in the middle of the slots 51, which may cause the bracket 1 to tilt and slip.

[0029] like Figure 1 , Figure 2 and Figure 5 As shown, a sealing gasket 6 is fixedly attached to the surface of the bracket 1; the sealing gasket 6 is set on the outside of the battery box 11; during operation, when the battery box 11 is installed on the vehicle, it fills the gap between the bracket 1 and the vehicle frame. By filling the gap through the sealing gasket 6, rainwater, mud, dust and other substances can be reduced from entering the battery box 11 when the vehicle is in motion, reducing the risk of short circuits in the battery cells or corrosion of metal parts. At the same time, the elastic material of the sealing gasket 6 can absorb road bumps, motor vibrations and other substances transmitted to the surface of the bracket 1, reducing the risk of fatigue cracking at the bolt holes of the bracket 1.

[0030] Working principle: By opening the cover plate 12, the battery is placed on the surface of the bracket 1, and then the cover plate 12 is closed. Then, the stepper motor 13 is controlled to rotate, and its output end drives multiple transmission rods 15 to rotate, causing the sliding block 16 to slide in the middle of the sliding groove 17, thereby driving the fixing block 18 to contact the battery surface for clamping. The heat generated by the battery during operation is transferred to the surface of the heat-conducting plate 21, and cooling gas is injected into one end of the heat dissipation copper pipe 2. The gas is discharged from the other end of the heat dissipation copper pipe 2. When the gas passes through the heat dissipation copper pipe 2, it carries away the heat from the surface of the heat-conducting plate 21, thus cooling the battery. The heat dissipation fins 3 transfer the heat from the surface of the heat dissipation copper pipe 2 to the outside air for heat dissipation. The heat generated by the battery during operation is discharged from multiple vents 4. The filter screen 41 intercepts impurities and dust in the outside air from entering the battery box 11. Multiple tools, such as ropes, are used to pass through a set of slots 51 to lift the bracket 1 as a whole for transportation. When the battery box 11 is installed on the car, it fills the gap between the bracket 1 and the car frame.
