[0035] In order to more clearly understand the above-mentioned objects, technical solutions and advantages of the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application, and a detailed understanding of how to solve the problems raised in the above background technology will be obtained.

[0036] It should be noted that: in this embodiment, the air vent valve 2 is a snap-type air vent valve 2. Among them, the auxiliary member 2 and the snap 21 are both plastic parts formed by injection molding, so that the snap 21 itself has sufficient strength and elasticity. Those skilled in the art can make it from well-known plastic materials, such as: polypropylene (PP), polyethylene (PE), polystyrene (PS), etc.

[0037] As Figures 1 to 6 shown, an anti-detachment structure of a snap-type air vent valve 2 includes: an air vent valve 2 fixedly installed on the upper cover 1. The air vent valve 2 includes a plurality of snaps 21, and there is a gap 211 between adjacent two snaps 21. The plurality of snaps 21 enclose an interface 212; an auxiliary member 3 fixedly installed on the upper cover 1. The auxiliary member 3 includes a clamping post 31, a plurality of clamping blocks 32 fixedly connected to the clamping post 31, and a fixing rod 33 fixedly connected to the clamping post 31. The fixing rod 33 is fixedly connected to the clamping blocks 32; wherein, the snap 21 is clamped with the upper cover 1, the fixing rod 33 is fixedly connected to the upper cover 1, the clamping post 31 is inserted into the interface 212, the clamping blocks 32 are embedded in the gap 211, and the clamping post 31 abuts against the snap 21.

[0038] Specifically, including but not limited to, in this embodiment, there are 3 buckles 21, and the buckle 21 is an arc-shaped structure. The 3 buckles 21 enclose to form a circular interface 212, and thereby form 3 gaps 211. The gaps 211 extend along the length of the buckle 21, so that multiple buckles 21 form a horn shape; the auxiliary part 3 as a whole can also be injection-molded. The fixing rod 33 is a rectangular rod. A clamping post 31 is arranged at one end of the fixing rod 33 facing the end face of the upper cover 1, so that the clamping post 31 protrudes upward relative to the fixing rod 33. The clamping block 32 is arranged along the side wall surface of the clamping post 31, and the bottom of the clamping block 32 is connected to the fixing rod 33, so that the clamping block 32 protrudes outward relative to the clamping post 31; the clamping post 31 and the interface 212, and the clamping block 32 and the gap 211 are all matched. Based on this, after the air vent valve 2 and the auxiliary part 3 are installed, the clamping post 31 is inserted into the interface 212 and contacts and fixes with the buckle 21. Correspondingly, the clamping block 32 is also embedded into the gap 211.

[0039] Through the above solution, the limit fixation of the buckle 21 can be achieved, and the friction between the buckle 21 and the upper cover 1 and the clamping post 31 can be prevented, the service life of the buckle 21 can be prolonged, thereby avoiding the detachment of the entire air vent valve 2, and improving the safety of the battery.

[0040] As a specific improvement embodiment, as Figure 4 shown, a sealing ring 22 is sleeved on the periphery of multiple buckles 21.

[0041] Specifically, including but not limited to, the sealing ring 22 is sleeved on the end of the buckle 21 away from the auxiliary part 3, which can avoid the phenomenon that the buckle 21 cannot expand outward after installation. And the sealing ring 22 is an O-shaped structure. The sealing ring 22 can be made of silica gel. The sealing ring 22 fits with the inner wall of the upper cover 1 to achieve sealing, and can effectively prevent pollutants such as dust, water, and oil from entering the battery interior.

[0042] As a specific improvement embodiment, as Figure 2 、 Figure 5 and Figure 6 shown, the width of the clamping block 32 gradually decreases along the direction towards the air vent valve 2.

[0043] Specifically, including but not limited to, the side surface of the clamping block 32 is coplanar with the side surface of the fixing rod 33. At this time, the top surface of the clamping block 32 facing the upper cover 1 is an arc surface, and the set length of the clamping block 32 is less than the distance between the top surface of the fixing rod 33 and the buckle 21. Thus, it can be avoided that the clamping block 32 blocks the gap 211. At the same time, the width of the clamping block 32 gradually decreases along the direction towards the air vent valve 2, which can not only ensure the limit of the clamping block 32 on the buckle 21, but also further prevent the blocking of the gap 211.

[0044] As a specific improvement embodiment, as Figure 2 、 Figure 5 andFigure 6 As shown, the auxiliary part 3 further includes a fixing sleeve 34 fixedly connected to the fixing rod 33. Correspondingly, the upper cover 1 is provided with a fixing post 11. One end of the fixing sleeve 34 is sleeved on the fixing post 11, and a locking member 4 is provided at the other end of the fixing sleeve 34. The locking member 4 is fixedly connected to the fixing post 11.

[0045] Specifically, including but not limited to, there are circular grooves at both ends of the fixing sleeve 34, and through holes are opened at the centers of the circular grooves. One end of the fixing rod 33 is connected to the side wall of the fixing sleeve 34, so that the fixing rod 33 and the fixing sleeve 34 are perpendicular to each other. The fixing rod 33 and the fixing sleeve 34 can be integrally formed by injection molding. Correspondingly, a fixing post 11 with a threaded structure is provided on the bottom surface of the upper cover 1. The fixing post 11 is embedded in the circular groove of the fixing sleeve 34, so that the fixing sleeve 34 is sleeved on the fixing post 11. The locking member 4 can be a screw, and the through hole of the fixing sleeve 34 is also provided with a threaded structure. Thus, the locking member 4 can pass through the fixing sleeve 34 and then be connected to the fixing post 11, thereby realizing the fixation of the fixing rod 33.

[0046] Through the above solution, the mutual cooperation structure of the fixing sleeve 34 and the fixing post 11 can realize the limit fixation of the auxiliary part 3 relative to the upper cover 1 and ensure the stability of the structure.

[0047] As a specific embodiment of the improvement, as Figure 5 and Figure 6 shown, the clamping post 31 is provided with a first ventilation hole 311, and the fixing rod 33 is provided with a second ventilation hole 331. The first ventilation hole 311 is communicated with the second ventilation hole 331.

[0048] Specifically, including but not limited to, both the first ventilation hole 311 and the second ventilation hole 331 are through holes. Since the clamping post 31 is arranged at the center of the side of the fixing rod 33 facing the air permeable valve 2, the first ventilation hole 311 and the second ventilation hole 331 are coaxially arranged. The clamping post 31 and the fixing rod 33 are integrally injection molded. The first ventilation hole 311 and the second ventilation hole 331 are communicated with each other, and their diameters can be set according to actual applications and are not specifically limited here.

[0049] Through the above solution, the first ventilation hole 311 and the second ventilation hole 331 are communicated with each other, which can further ensure the gas flow and avoid affecting the effect of the air permeable valve 2 after installing the auxiliary part 3.

[0050] As a specific embodiment of the improvement, as Figure 5 and Figure 6 shown, the clamping post 31 is of a conical or cylindrical structure.

[0051] Specifically, including but not limited to, in this embodiment, the clamping post 31 has a conical structure. The diameters of the front end of the clamping post 31 and the fixed rod 33 are larger than the diameter of the end inserted into the insertion interface 212. When the auxiliary member 3 is installed, there is a gap between the buckle 21 and the top surface of the auxiliary member 3. At this time, the diameter of the front end of the clamping post 31 is larger than the diameter of the interface 212, and the diameter of the front end of the clamping post 31 is smaller than the diameter of the connection hole 14, ensuring that the buckle 21 can be expanded after the clamping post 31 is inserted, and the conical structure of the clamping post 31 can expand the outermost end of the buckle 21, thus avoiding excessive bending of the buckle 21. Of course, in some embodiments, the clamping post 31 can also be set to a cylindrical structure.

[0052] As a specific embodiment of the improvement, as Figures 1 to 3 shown, an installation hole 12 is provided on the top surface of the upper cover 1, the air vent valve 2 is fixedly installed in the installation hole 12, a convex protrusion 13 is provided on the bottom surface of the upper cover 1, the convex protrusion 13 corresponds to the installation hole 12, and a connection hole 14 is provided in the convex protrusion 13, and the connection hole 14 communicates with the installation hole 12.

[0053] Specifically, including but not limited to, both the installation hole 12 and the connection hole 14 are cylindrical holes, and the installation hole 12 and the connection hole 14 communicate with each other to penetrate the entire upper cover 1. The air vent valve 2 is installed in the installation hole 12, the buckle 21 is clamped with the convex protrusion 13, and there is an arc-shaped wall surface between the connection hole 14 and the installation hole 12, which is convenient for the installation of the air vent valve 2 and can also be attached to the sealing ring 22 to prevent external dust and other impurities from entering.

[0054] As a specific embodiment of the improvement, as Figure 1 and Figure 2 shown, the convex protrusion 13 is provided with two parallel limiting blocks 15, and the fixed rod 33 is placed between the two limiting blocks 15.

[0055] Specifically, including but not limited to, the two limiting blocks 15 are provided on the bottom surface of the convex protrusion 13. The limiting blocks 15 are rectangular blocks, and the limiting blocks 15 are provided on the wall surface of the convex protrusion 13 closest to the fixed column 11, which can ensure that the linear distance from the fixed column 11 to the center of the connection hole 14 is the smallest, that is, the forming length of the fixed rod 33 can be reduced, thereby saving production costs. The fixed rod 33 is placed between the two limiting blocks 15, and there is a gap between the fixed rod 33 and the convex protrusion 13 to avoid extrusion when the fixed rod 33 is fixed. It should be noted that the height of the convex protrusion 13 corresponds to the height of the fixed column 11.

[0056] Through the above solution, the two limiting blocks 15 can limit the fixed rod 33 to prevent the fixed rod 33 from moving during fixation and avoid the phenomenon that the center of the clamping post 31 is offset from the connection hole 14.

[0057] Finally, it should be noted that the above is only the preferred embodiment of the present utility model, and the protection scope of the present utility model is not limited to the above embodiments. All technical solutions falling within the idea of the present utility model belong to the protection scope of the present utility model. It should be pointed out that for those of ordinary skill in the art, several improvements and refinements made without departing from the principle of the present utility model should also be regarded as within the protection scope of the present utility model.
