Description

Technical Field

[0001] This utility model belongs to the technical field of battery accessories, specifically relating to the structure of a self-locking battery cover. Background Technology

[0002] Currently, most manufacturers use epoxy resin to bond the battery cover and sealing cover in order to prevent dust and protect the terminals, and then cure the epoxy resin in a high-temperature curing oven for 1 to 2 hours, which increases resources and wastes time.

[0003] Therefore, how to provide a structure for a self-locking battery cover is a problem that urgently needs to be solved by those skilled in the art. Utility Model Content

[0004] In view of this, the present invention provides a structural design for a self-locking battery cover, which aims to protect the top cover of the battery and protect the terminals, while adding an anti-vibration structural design, which not only improves the efficiency of sealing the battery cover, but also improves the safety and reliability of the battery.

[0005] To achieve the above objectives, this utility model adopts the following technical solution: a structure for a self-locking battery cover, comprising:

[0006] A battery top cover, wherein the top four edges of the battery top cover are provided with multiple hooks and buckles, and the top four edges of the battery top cover are provided with multiple concave positioning parts, which are interspersed among the multiple hooks and buckles.

[0007] A battery sealing cover is adapted to be connected to the top of the battery top cover. The bottom periphery of the battery sealing cover is provided with multiple snap-fit ​​buckles, which correspond one-to-one with multiple hook-fit buckles and engage with each other. The bottom periphery of the battery sealing cover is provided with multiple convex positioning members, which are located at the positions corresponding to the concave positioning members. The concave positioning members and convex positioning members are engaged with each other and restrict the lateral misalignment of the battery top cover and the battery sealing cover.

[0008] The beneficial effects of this utility model are: the battery sealing cover is connected to the top cover of the battery, which can protect the top cover of the battery and protect the terminals. The multi-structure snap-fit ​​cooperation between the battery sealing cover and the top cover of the battery can prevent vertical detachment and ensure horizontal stability, prevent misalignment, and has good vibration resistance. It not only improves the efficiency of the battery sealing cover, but also improves the safety and reliability of the battery.

[0009] Preferably, the middle area of ​​the battery top cover is provided with multiple elongated hooks, and the bottom middle area of ​​the battery sealing cover is provided with multiple snap fasteners for connecting the hooks.

[0010] The resulting technical effect is that a hook-and-loop fastener is also provided in the middle area of ​​the battery top cover, but its length is longer and the hook-and-loop range is larger, which facilitates the connection with the snap-fit ​​fastener on the battery sealing cover. The purpose of this is to increase the number of connection points, so that the larger flat surface of the battery sealing cover receives strong support and restraint after being fastened with the battery top cover. In this way, the battery top cover and the battery sealing cover form a stable whole, with support and restraint at the four sides and the center, achieving the purpose of vibration resistance.

[0011] Preferably, the concave positioning member has shallow grooves on its two inner sidewalls, and the convex positioning member has flanges on both sides of its head that mate with the shallow grooves, and the convex positioning member is adapted to lock into the interior of the concave positioning member.

[0012] The resulting technical effect is that the combination of the concave and convex positioning parts restricts the horizontal separation of the battery top cover and the battery sealing cover.

[0013] Preferably, the width of the hollowed-out area in the middle of the concave positioning member is D1, and the width of the head body of the convex positioning member is D2, wherein the size of D1 is 0.1mm to 0.2mm smaller than the size of D2.

[0014] The resulting technical effect is that the head of the convex positioning component is larger than the recess of the concave positioning component. This is to ensure that the concave positioning component and the convex positioning component fit more tightly after being fastened, so as to prevent horizontal movement and stabilize the device.

[0015] Preferably, the hook buckle is provided with a hooking surface, the snap buckle is provided with a snapping surface, and when the hooking surface and the snapping surface are locked together, there is a pre-tensioning assembly distance of 0.1mm to 0.3mm in the vertical direction.

[0016] The resulting technical effect is that, understandably, the hook face on the hook buckle and the snap face on the snap fastener have a pre-tensioned distance in the vertical direction. In other words, the hook buckle and the snap fastener are assembled more tightly, making the lock more secure and preventing them from easily coming apart vertically.

[0017] Preferably, when the battery top cover and the battery sealing cover are engaged, there is a gap of 0.1mm to 0.3mm between the bottom of the snap fastener and the top surface of the battery top cover.

[0018] The resulting technical effect is that there is an assembly gap between the bottom of the snap-fit ​​and the top of the battery cover, ensuring that the snap-fit ​​and hook-fit are properly engaged, and also ensuring that the battery cover and the battery sealing cover are securely fastened together.

[0031] In some other specific embodiments, the concave positioning member 12 has shallow grooves on its two inner sidewalls, and the convex positioning member 22 has flanges on both sides of its head that mate with the shallow grooves. The convex positioning member 22 is adapted to lock into the interior of the concave positioning member 12. The cooperation between the concave positioning member and the convex positioning member relies on their structural features to achieve horizontal restriction of the battery top cover and the battery sealing cover.

[0032] In some other embodiments, the width of the hollowed-out area in the middle of the concave positioning member 12 is D1, and the width of the head body of the convex positioning member 22 is D2. The size of D1 is 0.1mm to 0.2mm smaller than the size of D2, which can ensure the locking degree of the convex positioning member and the concave positioning member.

[0033] In some other specific embodiments, the hook buckle 11 is provided with a hooking surface, the snap buckle 21 is provided with a snapping surface, P2 is the hooking surface, P3 is the snapping surface of the snap buckle, and when the hooking surface and the snapping surface are locked together, there is a pre-tensioning assembly distance of 0.1mm to 0.3mm in the vertical direction, which can ensure the tightness of the battery top cover and the battery sealing cover in the vertical direction.

[0034] In other embodiments, when the battery top cover 1 and the battery sealing cover 2 are fastened together, there is a gap of 0.1mm to 0.3mm between the bottom of the snap fastener 21 and the top surface of the battery top cover, where P1 is the top inner surface of the battery top cover and P4 is the bottom of the snap fastener.

[0035] This design ensures that the battery top cover 1 and the battery sealing cover 2 are securely fastened together. At the same time, the design structure of the positive hook 11 at the center of the battery top cover 1 and the negative hook 21 at the center of the battery sealing cover 2, combined with the surrounding buckles, makes the battery sealing cover 2 more secure after being fastened. The battery top cover and the battery sealing cover of this product form a stable whole, with support and restriction on separation at the four sides and the center, which serves the purpose of vibration resistance.

[0036] Compared with existing technologies, it does not require epoxy resin bonding and high-temperature curing for 1-2 hours, and can be directly snapped together for easy operation.

[0037] The apparatus and methods disclosed in the embodiments are described simply because they correspond to the methods disclosed in the embodiments. For relevant details, please refer to the method section.
