[0031] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0032] In order to solve the technical problem that the bus and wiring harness in the battery pack are currently bundled separately, resulting in a large number of buckle structures in the battery pack, inconvenient operation, increased cost, and occupation of the already crowded space in the battery pack, this embodiment provides a buckle structure that is compatible with fixing the wiring harness and the bus. When used in the battery pack, the wire harness and the bus can be fixed at the same time, and the functions of fixing the wire harness and fixing the bus are integrated into one buckle structure, which can effectively reduce the number of buckles in the battery pack and reduce the space occupied in the battery pack. It is also convenient to operate and reduces costs.

[0033] Reference Figure 1-Figure 3 The buckle structure of this embodiment, which is compatible with fixing the wiring harness and the bus, includes a top buckle mechanism 100, a middle buckle mechanism 200 and a bottom buckle mechanism 300 which are arranged in sequence from top to bottom.

[0034] The top buckle mechanism 100 is used to fix the wiring harness. Figure 4, the top buckle mechanism 100 of this embodiment includes a base column 101 and two cable ties 102. The base column 101 is arranged vertically. In this embodiment, the shape of the recess 107 is an irregular door-shaped structure. Of course, in other embodiments, the recess 107 may also be other structures. The two opposite sides of the base column 101 are integrally formed with an arc-shaped support plate 103, and the two arc-shaped support plates 103 are symmetrically arranged about the base column 101, and the arc-shaped openings of the arc-shaped support plates 103 face upward. In this embodiment, the curvature of the arc-shaped support plate 103 is 90 degrees. Of course, in other embodiments, the curvature of the arc-shaped support plate 103 may also be other angles, such as 100 degrees or 85 degrees. In this embodiment, the width of the arc-shaped support plate 103 is not specifically limited and can be reasonably set according to actual conditions. The arc-shaped support plate 103 and the base column 101 are connected with an arc-shaped insertion hole 104, and the side of the arc-shaped support plate 103 away from the base column 101 is provided with a guide notch 106 extending inward and matching with the cable tie 102. Two cable ties 102 are respectively arranged on both sides of the base column 101 and are respectively arranged one-to-one with the two arc-shaped support plates 103. One end of the cable tie 102 is integrally formed with a connecting buckle 108, and the connecting buckle 108 is provided with a card slot 105. The other end of the cable tie 102 passes through the insertion hole 104 and the guide notch 106 in sequence and is inserted into the card slot 105 of the connecting buckle 108.

[0035] It should be noted that the top buckle mechanism 100 of this embodiment can be injection molded using PP material or ABS material. When using mold injection molding, the material has a shrinkage rate. If the base column is solid, the wall thickness is too thick, it is easy to shrink and the size is easy to deform. The other two opposite sides of the base column 101 are both inwardly concave to form a concave cavity 107, so that the wall thickness of the base column 101 is uniform, and the two sides of the concave cavity 107 form ribs, which have the effect of increasing strength and preventing deformation.

[0036] With the above structure, when used to fix the wire harness, firstly insert the cable tie 102 into the arc-shaped insertion hole 104 on the arc-shaped support plate 103, put the wire harness on the arc-shaped support plate 103, and finally insert one end of the cable tie 102 through the guide notch 106 and then insert it into the card slot 105 that is connected to the connecting buckle 108. It should be noted that the cable tie 102 is an independent part and can be removed from the base column 101.

[0037] The middle buckle mechanism 200 is used to fix the busbar. Figure 5The middle buckle mechanism 200 of this embodiment includes a base 201 and a fixed upper cover 203. The base 201 is a rectangular structure, and a rectangular fixing groove 202 adapted to the bus structure is provided through the base 201. The bus can directly pass through the fixing groove 202 and be fixed on the base 201. In this embodiment, the four corners of the fixing groove 202 are all provided with rounded corners. The top of the base 201 is integrally formed with a connecting platform 204, a limiting platform 206, and a T-shaped platform 205, which are arranged in sequence. The height of the T-shaped platform 205 is slightly higher than that of the limiting platform 206, so as to cooperate between the limiting platform 206 and the T-shaped platform 205 to form a second card slot 207. A flexible arc piece 208 is integrally formed at one end of the fixed upper cover 203 and the flexible arc piece 208 is integrally connected to the connecting platform 204. The thickness of the flexible arc piece 208 is thinner than that of the fixed upper cover 203, so that the fixed upper cover 203 can rotate relative to the card base 201. A hook 209 adapted to the second card slot 207 is integrally formed at one end of the fixed upper cover 203 away from the connecting platform 204, and the hook 209 can be snapped into the second card slot 207. An elastic oblique rib 211 inclined toward the connecting platform 204 is integrally formed on the side of the fixed upper cover 203 facing the base. When the hook 209 is snapped into the second card slot 207, the fixed upper cover 203 and the card base 201 cooperate to form a locking slot 210 for locking the bus. In this embodiment, the base column 101 of the top buckle mechanism 100 is arranged on the side of the fixed upper cover 203 away from the base 201 and the base column 101 is integrally connected to the side of the fixed upper cover 203 close to the connecting platform 204. It should be noted that the middle buckle mechanism 200 of this embodiment can be made of PP material or ABS material.

[0038] Through the above structural arrangement, when the middle buckle mechanism 200 of this embodiment is used to fix the bus, there are two fixing methods, one of which can be selected or performed simultaneously according to the situation. The first method: the bus is fixed on the holder 201 by passing it through the fixing groove 202. The second method: manually bend the T-type stage 205 outward, rotate the fixed upper cover 203 outward along the flexible arc piece 208, open it, put the bus into the locking groove 210, rotate the fixed upper cover 203 inward along the flexible arc piece 208, and fix it by hooking it in the second slot 207 through the hook 209.

[0039] The bottom buckle mechanism 300 is used to realize the connection between the buckle structure of this embodiment and the battery pack box. Figure 6The bottom buckle mechanism 300 of this embodiment includes a post 301 and two cards 306. The post 301 is arranged below the card seat 201 and is connected to the card seat 201 as a whole. The bottom end of the post 301 is a circular structure and is provided with a dividing groove 302 extending from its bottom surface to its inside. The bottom sides of the post 301 are integrally formed with inclined pieces 303, and the two inclined pieces 303 are distributed in an inverted figure eight shape. The side of the inclined piece 303 away from the post 301 is spaced apart with a plurality of tooth-shaped grooves 304, and the top of the inclined piece 303 is integrally formed with a boss 305. The two cards 306 are distributed in an figure eight shape and one end of the two cards 306 is integrally connected to the top of the post 301. The end of the card 306 away from the post 301 is provided with a cylinder 307 and the card 306 is provided with a rectangular notch 308 extending from the middle of the cylinder 307 to its inside. It should be noted that the bottom buckle mechanism 300 of this embodiment can be made of PP material or ABS material.

[0040] Through the above structural arrangement, when the buckle structure of this embodiment is installed in the battery pack for fixing the wiring harness and the bus, the bottom buckle mechanism 300 is first connected to the battery pack case, and the clamping column 301 is inserted into the fixing hole of the battery pack case. The dividing groove 302 has a limiting function, so that the clamping column 301 can be clamped in the fixing hole of the battery pack case. The serrated groove 304 has a barb function, so that the clamping column 301 is buckled in the fixing hole of the battery pack case. The card 306 has a certain elasticity. When fixing the clamping column 301, the card 306 contacts the surface of the case. The card 306 has an upward rebound force, which cooperates with the serrated groove 304 to tightly fix the clamping column 301 in the fixing hole of the battery pack case.
