Detachable connecting structure between the electric product and the battery pack

Abstract

This provides a detachable connecting structure between an electric product and a battery pack. [Solution] The structure comprises a connecting female head 20 provided on the electric product and a connecting male head 40 provided on the battery pack. The connecting female head is provided with a recessed groove structure, and the connecting male head is convex, with the connecting male head fitted into the recessed groove structure. Between the connecting male head and the recessed groove structure, there is an insertion structure for electrical connection and an engagement structure that engages by rotation. This design enables stable connection and rapid disconnection between the battery pack and the electric product. Furthermore, the insertion conductor of the battery pack is provided inside the connecting male head, and since the connecting male head is convex outward, the thickness of the battery pack body can be appropriately reduced, which is advantageous for miniaturizing the battery pack.

Description

Technical Field

[0005] , , , ,

[0001] The present invention relates to the technical field of high-pressure washers, and specifically to the connection structure of battery packs.

Background Art

[0002] Electric products require corresponding battery packs, and the battery packs and electric products are detachably connected. When using an electric product, the battery pack is connected to the electric product to supply power to the electric product. When not in use or when the battery pack needs to be charged, the battery pack is removed from the electric product.

Summary of the Invention

Problems to be Solved by the Invention

[0003] The technical problem to be solved by the present invention is to provide a detachable connection structure between the battery pack and the electric product to achieve stable connection and rapid separation between the two.

Means for Solving the Problems

[0004] To solve the above technical problems, the present invention provides the following technical means: A detachable connection structure between an electric product and a battery pack, comprising a female connection head provided on the electric product and a male connection head provided on the battery pack. The female connection head is provided with a concave groove structure, the male connection head has a convex shape, and the male connection head is fitted into the concave groove structure. Between the male connection head and the concave groove structure, an insertion structure for electrical connection and an engagement structure engaged by rotation are provided.

[0005] According to the above technical means, first, the connecting male head is fitted axially into the groove structure of the connecting female head, and the two are electrically connected by an insertion structure for electrical connection, thereby achieving an electrical connection between the electric product and the battery pack. Then, the connecting male head and the connecting female head are rotated relative to each other, and the two are engaged by an engagement structure, thereby achieving a physical connection between the battery pack and the electric product. To separate them, they can be rotated in the opposite direction by a predetermined angle.

[0006] In one optional embodiment, the insertion structure for electrical connection comprises a plug provided in a groove structure and a jack provided on a connecting male head, wherein the plug is provided on a rotating block and the rotating block is movably fitted into the groove structure.

[0007] The rotating block is provided with an arc-shaped groove, and a hole for the rotating block is provided in the connecting female head body. The connecting female head body is provided with a stopper protrusion, which fits into the arc-shaped groove. After the plug and jack are mated, when the connecting male head is rotated relative to the connecting female head, the stopper protrusion moves along the arc-shaped groove, and the arc-shaped groove restricts the angle of movement of the stopper protrusion, further restricting the relative rotation angle between the connecting male head and the connecting female head.

[0008] An elastic member is provided on the side of the rotating block, and a positioning groove is provided on the side wall of the hole in which the rotating block is positioned, with a protrusion of the elastic member fitting into the positioning groove. When the rotating block is rotated relative to the connecting female head body, and the protrusion of the elastic member fits into the positioning groove, the connecting male head and connecting female head are in the detached position or the locked position.

[0009] A positioning projection is provided within the groove structure, and a positioning recess is provided on the connecting male head that engages with the positioning projection. When the rotating block is rotated relative to the connecting female head body, and the positioning projection engages with the positioning recess, the connecting male head and connecting female head are in a detached position or a locked position.

[0010] The inner wall of the groove structure is intermittently provided with a first convex edge, and the outer wall of the connecting male head is intermittently provided with a second convex edge. When the connecting male head and the connecting female head are fitted together in the axial direction, the first convex edge enters the gap between adjacent second convex edges, and then by rotating them, the first and second convex edges overlap (including partial or complete overlap). When the first and second convex edges overlap, the connecting male head and the connecting female head are locked together. [Effects of the Invention]

[0011] This invention has the following beneficial effects. 1. It enables stable connection and rapid disconnection between the battery pack and the electric product;

[0012] 2. The battery pack's insertion conductor (provided to correspond to the jack) is located within the connecting male head, and the connecting male head has an outward convex shape, which allows for a reasonable reduction in the thickness of the battery pack body, thus contributing to the miniaturization of the battery pack. [Brief explanation of the drawing]

[0013] The present invention will be described in more detail below with reference to the drawings. [Figure 1] Assembly perspective view of the electric product 10 and battery pack 30.
