Abstract
Description
Technical Field
[0001] This utility model belongs to the field of battery pack technology, specifically relating to a battery pack that prevents tilting. Background Technology
[0002] In the manufacturing process of some battery packs, it is necessary to wrap the entire outer surface of the battery with a protective film. The battery packaging film is a thin film material that is attached to the surface of the battery and plays the role of isolating air and moisture and protecting the battery.
[0003] In the prior art, during long-term use, the connection between the packaging film and the battery pack is prone to uneven deformation. In severe cases, this can lead to warping or wrinkling, which reduces the protective effect of the packaging film on the product and limits the use of the device.
[0004] Therefore, a battery pack that prevents warping is needed to solve the problem in the existing technology where the connection between the packaging film and the battery pack is prone to uneven deformation, which in severe cases can lead to warping or wrinkling. Utility Model Content
[0005] The purpose of this invention is to provide a battery pack that prevents tilting, so as to solve the problems mentioned in the background art.
[0006] To achieve the above objectives, the present invention provides the following technical solution: an anti-tilting battery pack, comprising a battery pack body, a wrapping film wrapped around the outer surface of the battery pack body, and an anti-tilting mechanism acting on the wrapping film;
[0007] The anti-tilting mechanism includes four protective sleeves located at the four corners of the wrapping film, two clamps fixed to one side of the protective sleeve, a connecting plate fixed to the middle position of the two clamps on the same side, a sliding rod evenly slidably inserted through the surface of the connecting plate, a fixing plate fixed to one end of the sliding rod, a spring sleeved on the outer periphery of the sliding rod near the fixing plate, a pressure sleeve sleeved on the outer periphery of the sliding rod away from the fixing plate, and a guide component acting on the pressure sleeve.
[0008] It should be noted in the solution that the inner surface of the protective sleeve is in contact with the surface of the wrapping film, and the inner surface of the clamp is in contact with the surface of the wrapping film.
[0009] It is worth noting that one end of the spring is fixed to the surface of the adjacent fixed plate, and the other end of the spring is fixed to the surface of the adjacent connecting plate.
[0010] Furthermore, it should be noted that the guide component includes an annular groove formed on the inner surface of the pressure sleeve and a limiting ring slidably inserted inside the annular groove, wherein the inner circumferential surface of the limiting ring is fixed to the outer circumferential surface of the adjacent sliding rod.
[0011] In a preferred embodiment, the anti-warping mechanism further includes a connection limiting component acting on the pressure sleeve. The connection limiting component includes a slot formed on one side of the outer surface of the pressure sleeve, a connecting plate inserted at the middle position of the two slots, and a bolt threaded to the top of the outer surface of the pressure sleeve.
[0012] In a preferred embodiment, the anti-tilting mechanism further includes a threaded cylinder fixed to one end of the protective sleeve at an adjacent position of the clamp, a threaded rod threaded to the inner walls of the two threaded cylinders at the same end, and a fastening cap threaded to both sides of the outer circumferential surface of the threaded rod.
[0013] In a preferred embodiment, the surface of the fastening cap abuts against the surface of the adjacent threaded cylinder, and the two fastening caps at the same end are symmetrically distributed.
[0014] Compared with the prior art, the anti-tilting battery pack provided by this utility model has at least the following beneficial effects:
[0015] (1) By wrapping the four protective sleeves around the four corners of the battery pack body and attaching the wrapping film to the four corners, and by having the clamps press against the surface of the wrapping film and the pressure sleeves press against the surface of the wrapping film under the action of the spring rebound force, the wrapping film can be restricted, so that the connection between the battery pack body and the wrapping film is less likely to deform asynchronously. This can prevent the wrapping film from peeling or wrinkling after long-term use, thereby improving the applicability of the device.
[0016] (2) By rotating the threaded rod located inside one of the threaded cylinders to extend one side into the interior of the other threaded cylinder, and rotating the fastening cap to make it abut against the surface of the adjacent threaded cylinder, the two sets of protective sleeves can be limited, thereby completing the installation and fixing of the connecting plate and making it easy to remove the connecting plate, thereby performing maintenance work on the battery pack body and the wrapping film.

[0023] The following description is intended to disclose the present invention so that those skilled in the art can implement it. The preferred embodiments described below are merely examples, and other obvious variations will occur to those skilled in the art.
[0024] Example 1
[0025] Please see Figure 1-5 This utility model provides an anti-tilting battery pack, including a battery pack body 1, a wrapping film 2 wrapped around the outer surface of the battery pack body 1, and an anti-tilting mechanism acting on the wrapping film 2.
[0026] The anti-tilting mechanism includes four protective sleeves 3 located at the four corners of the wrapping film 2, two clamps 4 fixed to one side surface of the protective sleeve 3, a connecting plate 5 fixed to the middle position of the two clamps 4 on the same side, a sliding rod 6 evenly slidably inserted through the surface of the connecting plate 5, a fixing plate 7 fixed to one end surface of the sliding rod 6, a spring 8 sleeved on the outer periphery of the sliding rod 6 near the fixing plate 7, a pressure sleeve 9 sleeved on the outer periphery of the sliding rod 6 away from the fixing plate 7, and a guide component acting on the pressure sleeve 9.
[0027] The inner surface of the protective sleeve 3 is in contact with the surface of the wrapping film 2, the inner surface of the clamp 4 is in contact with the surface of the wrapping film 2, one end of the spring 8 is fixed to the surface of the adjacent fixed plate 7, and the other end of the spring 8 is fixed to the surface of the adjacent connecting plate 5.
[0028] When it is necessary to restrict the wrapping film 2 covering the surface of the battery pack body 1, the inner surfaces of the two sets of protective sleeves 3 are wrapped around the surface of the wrapping film 2 in sequence. During this process, the clamp 4 will also abut against the surface of the wrapping film 2. After that, the sliding rod 6 is pulled so that the fixed plate 7 can abut against the spring 8 at the adjacent position to cause it to compress and deform. Under the action of the guide component, the pressure sleeve 9 can change its angle so that it can move to one end of the wrapping film 2. Then the pressure sleeve 9 is released so that the pressure sleeve 9 can move vertically under the action of the spring 8 at the adjacent position, so that it abuts and presses against the surface of the wrapping film 2. Thus, the protective sleeve 3, the clamp 4 and the pressure sleeve 9 can prevent the wrapping film 2 from lifting up during long-term use.
[0029] Please refer to Figure 1-5 As shown, the guide component includes an annular groove 10 formed on the inner surface of the pressure sleeve 9 and a limiting ring 11 slidably inserted inside the annular groove 10. The inner circumferential surface of the limiting ring 11 is fixed to the outer circumferential surface of the adjacent sliding rod 6.
[0030] The contact between the inner surface of the annular groove 10 and the outer circumferential surface of the limiting ring 11 allows the pressure sleeve 9 to rotate smoothly, thereby allowing the pressure sleeve 9 to change its angle to one end of the wrapping film 2.
[0031] Please refer to Figure 1-5 As shown, the anti-tilting mechanism also includes a connection limiting component acting on the pressure sleeve 9. The connection limiting component includes a slot 12 opened on one side of the outer surface of the pressure sleeve 9, a connecting plate 13 inserted in the middle of the two slots 12, and a bolt 14 threadedly connected to the top of the outer surface of the pressure sleeve 9.
[0032] Since the surfaces on both sides of the connecting plate 13 are provided with screw holes that are compatible with the bolt 14, after the connecting plate 13 is inserted into the middle position of the two adjacent pressure sleeves 9, the bolt 14 can be rotated to extend into the interior of the adjacent screw holes under the cooperation of the threaded structure, thereby limiting the two pressure sleeves 9 and preventing the pressure sleeves 9 from deflecting when they are playing an anti-warping role, thus ensuring the stability of the anti-warping role.
[0033] Example 2
[0034] Further in the embodiments, please refer to Figure 1-5 As shown, the anti-tilting mechanism also includes a threaded cylinder 15 fixed to one end of the protective sleeve 3 at the adjacent position of the clamp 4, a threaded rod 16 threaded to the inner wall of the two threaded cylinders 15 at the same end, and fastening caps 17 threaded to both sides of the outer circumferential surface of the threaded rod 16. The surface of the fastening cap 17 abuts against the surface of the adjacent threaded cylinder 15, and the two fastening caps 17 at the same end are symmetrically distributed.
[0035] After the two sets of protective sleeves 3 cover the four corners of the wrapping film 2, one side of the threaded rod 16 is located inside one of the threaded cylinders 15. By rotating the threaded rod 16, it can be extended horizontally, allowing the other side to extend into the interior of the other threaded cylinder 15 at the same end. By rotating the two fastening caps 17, they extend horizontally under the action of the threaded structure between them and the outer circumference of the threaded rod 16. This allows the fastening caps 17 to abut against the surface of the adjacent threaded cylinder 15, ensuring that the distance between the two sets of connecting plates 5 does not change. This completes the installation and fixing of the four protective sleeves 3. After the threaded rod 16 is extended into the interior of one of the threaded cylinders 15 and the fastening caps 17 are moved away from the adjacent threaded cylinder 15, the protective sleeves 3 can be disassembled.
