Description

Technical Field

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

[0002] A backup power battery pack is a device that provides power during mains power outages, primarily used to ensure that critical equipment can continue to operate during power interruptions. Backup power battery packs typically consist of batteries and inverters, providing a stable power output during mains power outages to prevent equipment from being damaged or ceasing operation due to sudden power failures.

[0003] Chinese patent CN213026315U discloses a portable backup power battery pack, comprising a battery module, a housing, and a clamping plate. The housing includes a frame-shaped shell with an upper opening. The battery module is disposed within the frame-shaped shell and is composed of multiple stacked cells arranged in the direction of cell expansion. The bottom surface of the battery module abuts against the bottom plate of the housing. The clamping plate is fixed to the upper opening of the frame-shaped shell and presses against the top surface of the battery module. This battery pack, through the cooperation of the clamping plate and the bottom plate of the frame-shaped shell, presses the battery module against the expansion direction of the cells, suppressing cell bulging and effectively preventing the risks associated with cell bulging. Furthermore, suppressing cell bulging effectively improves the cycle life of the battery pack.

[0004] The aforementioned battery pack has the effect of preventing cell expansion, but existing battery packs are inconvenient to carry, and the grip components are exposed and easily damaged. When in use, the battery pack is in direct contact with the ground, causing it to become damp and corroded. At the same time, the battery pack is in close contact with the outer casing, resulting in poor shock resistance and short service life. Therefore, there is a need to provide a lightweight backup power battery pack. Utility Model Content

[0005] The purpose of this utility model is to provide a lightweight backup power battery pack to solve the problems of existing battery packs being inconvenient to carry, susceptible to moisture and corrosion, and having poor shock resistance.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a lightweight backup power battery pack, comprising a housing, an outer shell fixedly mounted on the upper part of the housing, a battery pack fixedly mounted between the outer shell and the housing, and a gripping mechanism provided between the housing and the outer shell; the gripping mechanism includes four rivets, which pass through the housing and the outer shell; two irregularly shaped seats are rotatably mounted side by side on the outer shell, a rotating shaft is rotatably mounted through the irregularly shaped seats, a handle is fixedly mounted on the rotating shaft, two limiting grooves are provided side by side on one side of the handle, two slides are fixedly mounted side by side on both sides of the housing, a support spring is fixedly mounted inside the slide, a sliding rod is fixedly mounted on the upper part of the support spring, and a limiting strip is fixedly mounted on one side of the sliding rod and through the slide.

[0007] Preferably, trapezoidal grooves are provided on both sides of the box body, and the handle is adapted to match the trapezoidal grooves, and the handle is L-shaped.

[0008] Preferably, a square hole is provided on one side of the slide block, a triangular block is fixedly installed at the front end of the slide rod, and the limiting groove is adaptively matched with the triangular block.

[0009] Preferably, the battery pack is provided with a fixing mechanism on its exterior. The fixing mechanism includes a sealing plate. Two connecting plates are fixedly installed on the upper and lower sides of the battery pack. Two fastening bolts are fixedly installed through the two connecting plates. Four limiting bolts are fixedly installed through the housing and the sealing plate. Nuts are fitted on the exterior of the four limiting bolts and on the sealing plate. Two buffer springs are fitted on the exterior of the four limiting bolts and between the housing, the connecting plate and the sealing plate, respectively.

[0010] Preferably, the limiting bolt and the nut are respectively embedded in the housing and the sealing plate, and a circular groove is provided on the sealing plate below the nut.

[0011] Preferably, the inner diameters at both ends of the four buffer springs are different, and the two connecting plates are fitted and connected to the inner wall of the box.

[0012] Preferably, the connection ports of the backup power battery pack are all located on the side of the casing, and the positive and negative terminals of the battery pack are both set to a horizontal orientation.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1) This is a portable backup power battery pack. By controlling the rotation of the handle in the vertical and horizontal planes, the battery pack can be gripped or raised. When the handle is controlled to move away from the slide bar and rotated 207° in the vertical plane, a gripping space is formed on both sides, and the battery pack can be lifted by the two sides. When the handle is further rotated 180° in the horizontal plane, the battery pack can be flipped over for use. At this time, the battery pack is raised by the handle, avoiding direct contact with the ground and preventing problems such as corrosion of the casing or moisture in the battery pack.

[0015] 2) This portable backup power battery pack uses fastening bolts to fix the battery pack to two connecting plates, and limit bolts and nuts to fix the casing and sealing plate, ensuring the stability of the battery pack and the airtightness of the casing. At the same time, buffer springs are installed between the casing, connecting plates and sealing plates. The buffer springs can play a buffering role. When the battery pack is moved or is impacted, the buffer springs can provide good protection, thereby increasing the service life of the battery pack and greatly increasing the practicality of the battery pack.

Detailed Implementation

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. 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 protection scope of the present utility model.

[0023] Example 1

[0024] Combination Figures 1-5 A lightweight backup power battery pack includes a housing 1, an outer shell 2 fixedly installed on the upper part of the housing 1, a battery pack 3 fixedly installed between the outer shell 2 and the housing 1, and a gripping mechanism 4 provided between the housing 1 and the outer shell 2.

[0025] The gripping mechanism 4 includes four rivets 401, which pass through the housing 1 and the outer shell 2. Two irregular seats 402 are rotatably mounted side by side on the outer shell 2. A rotating shaft 403 is rotatably mounted through the irregular seats 402. A handle 404 is fixedly mounted on the rotating shaft 403. Two limiting grooves 405 are opened side by side on one side of the handle 404. Two slides 406 are fixedly mounted side by side on both sides of the housing 1. A support spring 407 is fixedly mounted inside the slide 406. A slide rod 408 is fixedly mounted on the upper part of the support spring 407. A limiting strip 409 is fixedly mounted on one side of the slide rod 408 and through the slide 406.

[0026] See Figure 3 Furthermore, trapezoidal grooves are provided on both sides of the housing 1, and the handle 404 is adapted to the trapezoidal grooves. The handle 404 is L-shaped. A square hole is provided on one side of the slide block 406. A triangular block is fixedly installed at the front end of the slide rod 408, and the limiting groove 405 is adapted to the triangular block.

[0027] Specifically, under the action of the support spring 407, the slide rod 408 is inserted into the limiting groove 405 and has a limiting effect on the handle 404. When an external force is applied to make the handle 404 rotate around the pivot 403, the two handles 404 merge into a gripping space. When the two handles 404 are further rotated 180° around the irregular seat 402, the box 1 can be flipped over. The handles 404 play a supporting role, so that the box 1 has no direct contact with the ground. When in use, the handles 404 can be stored by rotating the handles 404 so that the slide rod 408 is inserted into the limiting groove 405.

[0028] Example 2

[0029] Combination Figure 1 , Figure 2 and Figure 4The battery pack 3 is provided with a fixing mechanism 5 on its exterior. The fixing mechanism 5 includes a sealing plate 501. Two connecting plates 502 are fixedly installed on the upper and lower sides of the battery pack 3. Two fastening bolts 503 are fixedly installed through the two connecting plates 502. Four limiting bolts 504 are fixedly installed through the housing 1 and the sealing plate 501. Nuts 505 are fitted on the exterior of the four limiting bolts 504 and on the sealing plate 501. Two buffer springs 506 are fitted on the exterior of the four limiting bolts 504 and between the housing 1, the connecting plate 502 and the sealing plate 501, respectively.

[0030] See Figure 4 Furthermore, based on Embodiment 1, the limiting bolt 504 and nut 505 are respectively embedded in the housing 1 and the sealing plate 501. A circular groove is provided on the sealing plate 501 and located below the nut 505. The inner diameters of the two ends of the four buffer springs 506 are different. Both connecting plates 502 are in close contact with the inner wall of the housing 1.

[0031] Specifically, the battery pack 3 is fixed by controlling the fastening bolts 503 and the connecting plate 502, and the limit bolts 504 and nuts 505 are used to form a sealed space between the box body 1 and the sealing plate 501. A buffer spring 506 is sleeved on the outside of the limit bolts 504. The buffer spring 506 acts between the box body 1, the connecting plate 502 and the sealing plate 501. When the box body 1 is moved or the box body 1 is impacted, the buffer spring 506 plays a good buffering role and can prevent the battery pack 3 from being damaged by the impact.

[0032] Example 3

[0033] See Figure 2 Furthermore, based on Embodiment 1 and Embodiment 2, the connection ports of the backup power battery pack are all located on the side of the housing 1, and the positive and negative terminals of the battery pack 3 are both set to a horizontal orientation.

[0034] Specifically, by setting the connection port of the backup power battery pack on the side of the housing 1 and setting the positive and negative terminals of the battery pack 3 horizontally, the positive and negative terminals of the battery pack 3 will never be reversed when the battery pack 3 is flipped up and down, which can prevent the battery pack 3 from leaking and being damaged, and ensure the normal use of the battery pack 3.

[0035] In actual operation, under the action of the support spring 407, the slide rod 408 is embedded in the limiting groove 405 and the handle 404 is limited. When the external force is applied to make the handle 404 rotate around the rotating shaft 403, the two handles 404 merge into a gripping space. When the two handles 404 are rotated 180° around the irregular seat 402, the box 1 can be flipped over. The handles 404 play a supporting role, so that the box 1 has no direct contact with the ground. When in use, the handles 404 can be stored by rotating the handles 404 so that the slide rod 408 is embedded in the limiting groove 405.

[0036] The battery pack 3 is fixed by controlling the fastening bolts 503 and the connecting plate 502, and the box body 1 and the sealing plate 501 are sealed by using the limiting bolts 504 and the nuts 505. A buffer spring 506 is sleeved on the outside of the limiting bolts 504. The buffer spring 506 acts between the box body 1, the connecting plate 502 and the sealing plate 501. When the box body 1 is moved or the box body 1 is impacted, the buffer spring 506 plays a good buffering role and can prevent the battery pack 3 from being damaged by the impact.

[0037] By placing the backup power battery pack connection port on the side of the housing 1 and setting the positive and negative terminals of the battery pack 3 horizontally, the positive and negative terminals of the battery pack 3 will never be reversed when the battery pack 3 is flipped up and down, thus avoiding leakage and damage to the battery pack 3 and ensuring its normal use.

[0038] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to the embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
