Description

Technical Field

[0001] This utility model belongs to the field of power supply technology, specifically relating to a portable small lithium battery. Background Technology

[0002] A lithium battery is a rechargeable battery that works by moving lithium ions between positive and negative electrodes. Due to its advantages such as high energy density, long cycle life, low self-discharge rate and wide operating temperature range, lithium batteries are widely used in modern society. A lithium battery pack is a battery system composed of multiple lithium battery cells connected in series or parallel.

[0003] When users install lithium battery packs into equipment, or during equipment operation, lithium batteries inevitably experience vibrations, which can interfere with their normal operation and affect the normal operation of the equipment. In addition, lithium batteries may experience thermal runaway under overheating conditions, causing the internal temperature of the lithium battery pack to rise sharply. If the heat is not dissipated in time, it may cause a fire or explosion. Therefore, a portable small lithium battery is needed to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to provide a portable small lithium battery to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a portable small lithium battery, comprising:

[0006] Battery body;

[0007] The enclosure includes a breathable mesh panel and a shock-absorbing component. The shock-absorbing component is spaced between the inner wall of the enclosure and the breathable mesh panel. The shock-absorbing component includes a moving rod, a hollow cylinder, and a return spring. The moving rod is movably inserted into the hollow cylinder. The return spring is connected to the moving rod and the hollow cylinder. The end of the moving rod away from the return spring is connected to the breathable mesh panel. The end of the hollow cylinder away from the moving rod is connected to the inner wall of the enclosure.

[0008] An opening and closing mechanism is provided in the housing.

[0009] As a preferred embodiment, the housing further includes a movable cover and a sliding groove. The sliding groove is disposed at the upper end of the housing, and the movable cover is slidably disposed in the sliding groove. The movable cover has a vent hole that communicates with the space between the inner wall of the housing and the vent mesh plate.

[0010] As a preferred embodiment, the opening and closing mechanism includes a rotating rod, a fixing ring, and a fixing bolt. One end of the rotating rod is rotatably disposed at the upper end of the housing, and the other end of the rotating rod is connected to the fixing ring. The fixing ring is sleeved on the fixing bolt, and the movable cover also includes a threaded hole that matches the fixing bolt.

[0011] As a preferred embodiment, the rotating rods are provided in multiple pairs, and each pair of rotating rods is symmetrically distributed about the center of the housing.

[0012] As a preferred embodiment, the housing also includes handles, and two handles are provided, with the two handles respectively located on two opposite outer side walls of the housing.

The movable rod is movably inserted into the hollow cylinder, and the return spring is connected to both the movable rod and the hollow cylinder. The end of the movable rod furthest from the return spring is connected to a ventilated mesh plate, and the end of the hollow cylinder furthest from the movable rod is connected to the inner wall of the housing. When the housing is moved by a user or placed on operating equipment, the housing vibrates, causing the movable rod to move within the hollow cylinder. The return spring's rebound force prevents the ventilated mesh plate, the limiting component, and the battery body placed within the limiting component from colliding with the inner wall of the housing. This reduces the impact of external vibrations on the battery body, thereby minimizing damage and safety hazards caused by vibration.

[0016] This invention features an opening and closing mechanism comprising a rotating rod, a fixed ring, and a fixing bolt. One end of the rotating rod is rotatably mounted on the upper end of the housing, and the other end is connected to the fixed ring. The fixed ring is fitted onto the fixing bolt, and the movable cover includes a threaded hole that matches the fixing bolt. When the user needs to replace or disassemble the battery body, they manually rotate the fixing bolt, causing it to move away from the movable cover, which in turn moves the fixed ring and the rotating rod away from the movable cover. Then, the movable cover can be slid away from the slide groove. The operation is simple and efficient. Attached Figure Description

The conditions in the embodiments can be further adjusted according to specific conditions, and simple improvements to the method of the present invention under the premise of the concept of the present invention are all within the scope of protection claimed by the present invention.

[0024] Please see Figure 1-4 This utility model provides a portable small lithium battery, comprising:

[0025] Battery body 1;

[0026] Box 2 includes a breathable mesh panel 21 and a shock-absorbing component 22. The shock-absorbing component 22 is spaced between the inner wall of the box 2 and the breathable mesh panel 21. The shock-absorbing component 22 includes a moving rod 221, a hollow cylinder 222 and a return spring 223. The moving rod 221 is movably inserted into the hollow cylinder 222. The return spring 223 is connected to the moving rod 221 and the hollow cylinder 222. The end of the moving rod 221 away from the return spring 223 is connected to the breathable mesh panel 21. The end of the hollow cylinder 222 away from the moving rod 221 is connected to the inner wall of the box 2.

[0027] Opening and closing mechanism 3 is installed in housing 2;

[0028] The housing 2 also includes a movable cover 23 and a slide 24. The slide 24 is located at the upper end of the housing 2. The movable cover 23 is slidably located in the slide 24. The movable cover 23 has a vent hole 231. The vent hole 231 is connected to the space between the inner wall of the housing 2 and the vent mesh plate 21.

[0029] The opening and closing mechanism 3 includes a rotating rod 31, a fixing ring 32 and a fixing bolt 33. One end of the rotating rod 31 is rotatably disposed at the upper end of the housing 2, and the other end of the rotating rod 31 is connected to the fixing ring 32. The fixing ring 32 is sleeved on the fixing bolt 33. The movable cover 23 also includes a threaded hole 232 that matches the fixing bolt 33.

[0030] Multiple pairs of rotating rods 31 are provided, and each pair of rotating rods 31 is symmetrically distributed about the center of the box 2;

[0031] The housing 2 also includes handles 25, and two handles 25 are provided, with the two handles 25 respectively provided on two opposite outer side walls of the housing 2;

[0032] The housing 2 also includes a limiting member 26 for accommodating the battery body 1, the limiting member 26 being spaced apart on the side of the ventilated mesh 21 away from the shock-absorbing component 22.

[0033] Working principle and usage process of this utility model:

[0034] Multiple battery bodies 1 are individually placed in limiting member 26, and movable cover 23 is placed in slide groove 24. Fixing bolt 33 is threadedly connected to movable cover 23. The heat generated by multiple battery bodies 1 during operation is dissipated through the mesh on the ventilated mesh plate 21 to the space between the ventilated mesh plate 21 and the side wall of the box 2, and further discharged to the outside of the box 2 through the vent hole 231 on the movable cover 23. In this way, fire or explosion caused by excessive heat inside the box 2 is avoided, and the safety of the equipment is improved.

[0035] Furthermore, when the housing 2 is moved by the user or placed on a running device, the housing 2 vibrates, which in turn causes the moving rod 221 to move within the empty cylinder 222. Under the restoring force of the return spring 223, the moving rod 221 reciprocates within the empty cylinder 222. In this way, the ventilated mesh 21, the limiting member 26, and the battery body 1 placed in the limiting member 26 will not collide with the inner wall of the housing 2, thereby reducing the impact of external vibration on the battery body 1 and the damage and safety hazards caused by vibration.

[0036] When the user needs to replace or disassemble the battery body 1, manually rotate the fixing bolt 33 so that the fixing bolt 33 moves away from the moving cover 23, which in turn moves the fixing ring 32 and the rotating rod 31 away from the moving cover 23; then slide the moving cover 23 away from the slide groove 24. The operation method is simple and improves efficiency.

[0037] 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 these 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.
