Description

Technical Field

[0001] This utility model relates to the field of battery technology, specifically to a battery pack device. Background Technology

[0002] A battery pack is a device that combines multiple individual battery cells into a battery array. Its main function is to provide a stable power supply for various electronic products and devices. By combining individual battery cells, the voltage and current of the battery pack are accumulated to meet the operating requirements of the device. It consists of individual battery cells, a battery management system (BMS), protection circuitry, and a heat dissipation system, ensuring the safe and stable operation of the battery pack and providing appropriate heat dissipation to prevent overheating.

[0003] CN210073962U discloses a battery pack device, including a housing and a battery pack placed in the housing. A limiting strip is provided on the inner side wall of the housing for limiting the battery pack. The limiting strip is slidably connected to the housing. A first channel for placing cables is formed between the limiting strip and the corresponding connected side wall. A wiring mechanism for connecting the cables in the housing is provided in the first channel. The wiring mechanism is fixed to the housing by an insulating member.

[0004] To address the issue of messy and unsightly battery racks caused by difficult-to-organize battery cables, existing technologies employ a junction connection mechanism to efficiently place cables in the first channel. However, this approach suffers from a lack of robust protective housing structure, which fails to effectively withstand impacts, thus affecting the device's lifespan and applicability.

[0009] A further improvement of the present invention is that: the end of the connecting rod away from the first connecting member is rotatably connected to the second connecting member, the first protective pad is fixedly connected to one side of the second connecting member, and the second protective pad is fixedly connected to the bottom surface of the inner wall of the protective shell.

[0010] A further improvement of the present invention is that: a slot is provided on the top of the protective shell, a card is fixedly connected to the bottom of the slot, and a fixing member is fixedly connected to one side of the protective shell.

[0015] Due to the adoption of the above technical solution, the technological progress achieved by this utility model compared to the prior art is as follows:

[0016] 1. This utility model provides a battery pack device, which consists of a protective shell, a fixing groove, a fixing block, a spring, a connector, a connecting rod, a connector, a protective pad, and a protective pad. During use, the battery is fixed inside the protective shell. When one side of the protective shell is impacted, the protective pad on the surface of the protective shell absorbs part of the impact force. Then, the protective pad pushes the connector to move, causing the connector to rotate and move the connecting rod. This movement causes the connector to move, and the spring fixed to the fixing block undergoes compression deformation, thus further offsetting the impact force. After the impact ends, the spring extends and releases its elastic potential energy, causing the connecting rod to push the protective pad to move outwards from the fixing groove to reset and resist the next impact. Simultaneously, the protective pad protects the bottom of the battery, reducing the impact of external forces on the battery, thereby improving the practicality and lifespan of the device.

[0017] 2. This utility model provides a battery pack device, which uses a combination of a fixing component, a slot, a locking component, a limiting slot, a sliding slot one, a spring two, a locking pin, a through hole, a wiring plate, a wire clamping slot, a sliding slot, a spring three, a clamping plate, and a protective pad. In use, the wiring mechanism slides downwards along the limiting slot, pressing the locking pin and forcing the spring two to retract, causing the locking pin to be pressed into the sliding slot one until the wiring mechanism reaches the bottom of the protective shell. The locking pin is then pushed back by the spring two, fixing the wiring mechanism. Multiple protective mechanisms can be connected and fixed by inserting the locking component into the slot and securing it with screws. The fixing component can be used to fix the device to the battery rack. When organizing cables, simply insert the cable into the wire clamping slot, causing the cable to press against the clamping plate and forcing the spring three to retract into the sliding slot, thus quickly fixing the cable. The protective pad protects the cables. Cables between battery packs in multiple devices are connected through the through hole, facilitating quick installation and disassembly of the device and allowing for easy organization of internal cables for maintenance.

[0018] 3. This utility model provides a battery pack device that uses a fixing ring, a fixing shell, a motor, a fan, a moisture-absorbing plate, and a dustproof net in combination. When the battery is running, it generates heat. The motor is started, which drives the fan to rotate, accelerating the air circulation inside the device. External air passes through the dustproof net to filter dust and enters the protective shell to replace the hot air for heat dissipation. At the same time, to prevent the battery from getting damp, the moisture-absorbing plate absorbs the moisture in the external air, giving the device a good heat dissipation effect. This also prevents the battery from getting damp and dusty, thus improving the service life of the device. Attached Figure Description

[0025] The present invention will be further described in detail below with reference to embodiments:

[0026] Example 1

[0027] like Figure 1-5 As shown, this utility model provides a battery pack device, including a protection mechanism 1, a wiring mechanism 2 provided on the inner wall of the protection mechanism 1, and a heat dissipation mechanism 3 provided at one end of the protection mechanism 1; the protection mechanism 1 includes a protective shell 11, a fixing groove 12 is provided on one side of the protective shell 11, a fixing block 13 is fixedly connected to the inner wall of the fixing groove 12, a spring 14 is fixedly connected to the upper and lower ends of the fixing block 13, a connector 15 is fixedly connected to the end of the spring 14 away from the fixing block 13, a connecting rod 16 is rotatably connected to the inner wall of the connector 15, a second connector 17 is rotatably connected to the end of the connecting rod 16 away from the first connector 15, a protective pad 18 is fixedly connected to one side of the second connector 17, and a second protective pad 19 is fixedly connected to the bottom surface of the inner wall of the protective shell 11.

[0028] In this embodiment, the battery is fixed inside the protective shell 11 during use. When one side of the protective shell 11 is impacted, the protective pad 18 on the surface of the protective shell 11 will first absorb part of the impact force. Then, the protective pad 18 pushes the connector 17 to move, causing the connector 17 to drive the connecting rod 16 to rotate and move at the same time, thereby causing the connector 15 to move. At this time, the spring 14 fixed on the fixing block 13 will undergo compression deformation, thus offsetting the impact force again. After the impact ends, the spring 14 extends and releases elastic potential energy, causing the connecting rod 16 to push the protective pad 18 to move to the outside of the fixing groove 12 to reset, so as to resist the next impact. At the same time, the bottom of the battery can be protected by the protective pad 19.

[0029] Example 2

[0030] like Figure 1-5 As shown, based on Embodiment 1, this utility model provides a technical solution: the top of the preferred protective shell 11 is provided with a slot 111, the bottom of the slot 111 is fixedly connected with a clip 112, one side of the protective shell 11 is fixedly connected with a fastener 110, the inner wall of the protective shell 11 is provided with a limiting groove 113, the inner wall of the limiting groove 113 is provided with a sliding groove 114, the inner wall of the sliding groove 114 is fixedly connected with a spring 115, one end of the spring 115 is fixedly connected with a clip 116, the bottom surface of the inner wall of the protective shell 11 is provided with a wire hole 117, the wiring mechanism 2 includes a wiring plate 21, the outer wall of the wiring plate 21 is slidably connected to the limiting groove 113, the top of the wiring plate 21 is provided with a wire clamping groove 22, the inner wall of the wire clamping groove 22 is provided with a sliding groove 23, the inner wall of the sliding groove 23 is fixedly connected with a spring 24, one end of the spring 24 is fixedly connected with a clamping plate 25, and one side of the clamping plate 25 is fixedly connected with a protective pad 26.

[0031] In this embodiment, during use, the wiring mechanism 2 is slid downward along the limiting groove 113 to press the pin 116 and force the second spring 115 to retract, so that the pin 116 is pressed into the sliding groove 114 until the wiring mechanism 2 reaches the bottom of the protective shell 11. The pin 116 is pushed back by the second spring 115 to fix the wiring mechanism 2. By inserting the clip 112 into the clip groove 111 and fixing it with screws, multiple protective mechanisms 1 can be connected and fixed. The device can be fixed on the battery rack using the fixing member 110. When organizing the cables, simply insert the cable into the clamping groove 22, so that the cable presses the clamping plate 25 and forces the third spring 24 to retract into the sliding groove 23, so that the cable can be quickly fixed. The cable can be protected by setting the protective pad 26. The cables between the battery packs in multiple devices are connected to each other through the through hole 117.

[0032] Example 3

[0033] like Figure 1-5As shown, based on Embodiment 1, this utility model provides a technical solution: Preferably, the heat dissipation mechanism 3 includes a fixing ring 31, one side of the fixing ring 31 is fixedly connected to the protective shell 11, the inner wall of the fixing ring 31 is fixedly connected to the fixing shell 32, the inner wall of the fixing shell 32 is fixedly connected to the motor 33, the output end of the motor 33 is fixedly connected to the fan 34, the inner wall of the fixing shell 32 is fixedly connected to the moisture-absorbing plate 35, and one end of the fixing shell 32 is fixedly connected to the dustproof net 36.

[0034] In this embodiment, heat is generated when the battery is running. The motor 33 is started, which drives the fan 34 to rotate, accelerating the air circulation inside the device. External air passes through the dustproof net 36 to filter dust and enters the protective shell 11 to replace the hot air for heat dissipation. At the same time, the moisture-absorbing plate 35 absorbs the moisture in the external air to prevent the battery from getting damp.

[0035] The working principle of this battery pack device will be explained in detail below.

[0036] like Figure 1-5As shown, during use, the battery is fixed inside the protective casing 11. When one side of the protective casing 11 is impacted, the protective pad 18 on the surface of the protective casing 11 absorbs part of the impact force. Then, the protective pad 18 pushes the connector 17 to move, causing the connector 17 to rotate the connecting rod 16 and move it simultaneously, thus causing the connector 15 to move. At this time, the spring 14 fixed on the fixing block 13 undergoes compression deformation, which can further offset the impact force. After the impact ends, the spring 14 extends and releases its elastic potential energy, causing the connecting rod 16 to push the protective pad 18 to move to the outside of the fixing groove 12 to reset and resist the next impact. At the same time, the bottom of the battery can be protected by the protective pad 19. During use, the wiring mechanism 2 slides down along the limiting groove 113 to press down the pin 116 and force the spring 115 to contract, so that the pin 116 is pressed into the sliding groove 114 until the wiring mechanism 2 reaches the... Reaching the bottom of the protective shell 11, the clip 116 is pushed back to its original position by the spring 115, fixing the wiring mechanism 2. By inserting the clip 112 into the slot 111 and fixing it with screws, multiple protective mechanisms 1 can be connected and fixed. The device can be fixed on the battery rack using the fastener 110. When organizing the cables, simply insert the cable into the clamping groove 22, so that the cable squeezes the clamping plate 25 and forces the spring 24 to retract into the sliding groove 23, thereby allowing the cable to be quickly fixed. The cable can be protected by setting the protective pad 26. The cables between the battery packs in multiple devices are connected to each other through the through hole 117. Heat is generated when the battery is running, so the motor 33 is started. The motor 33 drives the fan 34 to rotate, accelerating the air circulation inside the device. The external air passes through the dust filter 36 to filter the dust and enters the protective shell 11 to replace the hot air for heat dissipation. At the same time, the moisture-absorbing plate 35 absorbs the moisture in the external air to prevent the battery from getting damp.

[0037] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
