[0035] The battery terminal connection structure will be described in more detail below with reference to the drawings, wherein the preferred embodiments of the battery terminal connection structure are shown, and it should be understood that those skilled in the art can modify the battery terminal connection structure described herein while still achieving the advantageous effects of the battery terminal connection structure. Therefore, the following description should be understood as extensive knowledge for those skilled in the art, and not as a limitation on the battery terminal connection structure.

[0036] As shown in the drawings, Figs. 1 to 3 An embodiment of the battery terminal connection structure is provided, which comprises a terminal body 1, a plurality of clamping blocks 2 and a pressing driving piece 3.

[0037] The terminal body 1 has a stepped surface for the insertion and support of the through hole of the connecting piece 4, that is, the connecting piece 4 can be sleeved on the terminal body 1 and lapped on the stepped surface.

[0038] The plurality of clamping blocks 2 are arranged in a ring shape inside the terminal body 1 and can be synchronously moved along the axial direction close to or away from the terminal body 1 to retract into the terminal body 1 or exposed outside the terminal body 1.

[0039] When the clamping block 2 is exposed outside the terminal body 1, it can be pressure connected with the upper surface of the connecting piece 4, that is, for limiting the connecting piece 4 so that the connecting piece 4 cannot be pulled out of the terminal body 1, realizing the connection of the two.

[0040] The pressing driving piece 3 is movably installed on the terminal body 1 and lapped with the upper surfaces of the plurality of clamping blocks 2, for pushing the plurality of clamping blocks 2 to be synchronously exposed outside the terminal body 1. That is, the pressing driving piece 3 controls the movement of the clamping block 2 to complete the pressure connection of the upper surface of the connecting piece 4.

[0041] In addition, the pressing driving piece 3 can also keep the clamping block 2 relatively fixed, that is, the clamping block 2 can be kept fixed when it is in the exposed state, thereby ensuring the connection effect between the connecting piece 4 and the terminal body 1.

[0042] The device can drive the pressing driving piece 3 to operate when the connecting piece 4 is sleeved and inserted on the stepped surface of the terminal body 1, so that the clamping block 2 is exposed and pressure connected with the upper surface of the connecting piece 4, thereby limiting the connecting piece 4, completing the connection of the connecting piece 4 and the terminal body 1, and achieving the purpose of quickly assembling the terminal body 1 and the connecting piece 4 without the aid of external tools.

[0043] In this embodiment, a specific pressing driving piece 3 is provided to better push the plurality of clamping blocks 2 to pressure connect with the upper surface of the connecting piece 4.

[0044] Specifically, the pressing driving piece 3 includes a movable column 31 having an extrusion end of a circular platform type structure for lapping with the clamping block 2.

[0045] The side of the clamping block 2 in contact with the extrusion end is provided with a wedge surface, so that when the movable column 31 is pressed down, the extrusion end extrudes the wedge surface to push the clamping block 2 to move away from the axial direction of the terminal body 1, complete the control of the clamping block 2 to be exposed outside the terminal body 1, and realize the pressure connection of the upper surface of the connecting piece 4.

[0046] Further, the pressing driving piece 3 further comprises a limiting block 32, which is arranged on the outer wall of the movable column 31, and the terminal body 1 is internally provided with a limiting groove 5 matched with the limiting block 32. By arranging the limiting block 32 and the limiting groove 5, the movable column 31 is always connected with the terminal body 1, so compared with the bolt connection in the prior art, the device also does not need to worry about the loss or falling of the pressing driving piece 3.

[0047] The limiting groove 5 comprises a vertical groove 51 and a horizontal arc-shaped groove 52 which are in communication with each other.

[0048] It should be noted that when the limiting block 32 is placed in the horizontal arc-shaped groove 52 (i.e. when the movable column 31 is pressed and rotated), the clamping block 2 is exposed outside the terminal body 1, and the movable column 31 is fixed in the height direction. Since the exposed length of the clamping block 2 is formed according to the extrusion of the wedge surface when the movable column 31 is pressed, when the height of the movable column 31 remains unchanged, the exposed length of the clamping block 2 also remains relatively fixed, that is, after the terminal body 1 is connected with the connecting piece 4, the clamping block 2 will not easily shrink into the terminal body 1, so as to ensure the stability of the connection between the terminal body 1 and the connecting piece 4.

[0049] It should be particularly noted that in order to avoid the wedge surface of the clamping block 2 interfering with the rotation of the movable column 31, the wedge surface is arranged in an arc-shaped structure and is matched with the extrusion end, so as to ensure that the limiting block 32 can be rotated into the horizontal arc-shaped groove 52 to fix the movable column 31 in the height direction.

[0050] In addition, in order to facilitate the rotation of the movable column 31 for subsequent disassembly and maintenance of the connecting piece 4 and the terminal body 1, the size of the movable column 31 is limited. Specifically, when the limiting block 32 is placed in the horizontal arc-shaped groove 52, the top end of the movable column 31 still protrudes outside the terminal body 1, which facilitates manual rotation of the movable column 31, so that the limiting block 32 can be deflected from the horizontal arc-shaped groove 52 into the vertical groove 51, that is, the clamping block 2 is no longer locked at this time, so the clamping block 2 can be shrunk into the terminal body 1 to separate the connecting piece 4 from the terminal body 1.

[0051] In other embodiments, the terminal body 1 is internally provided with a sliding groove for mounting the clamping block 2, and the sliding groove is internally provided with a torsional spring 21 connected with the clamping block 2. When the clamping block 2 is not subjected to the force of the pressing driving piece 3, the torsional spring 21 pulls the clamping block 2 to reset, so that the clamping block 2 is hidden inside the terminal body 1, which is convenient for subsequent disassembly and maintenance.

[0052] In further embodiments, the terminal body 1 comprises an upper column 11 and a lower column 12 connected from top to bottom and coaxially arranged, and the outer diameter of the lower column 12 is greater than that of the upper column 11 to form the stepped surface.

[0053] Wherein, the upper column 11 and the lower column 12 are integrally formed.

[0054] Obviously, those skilled in the art can make various modifications and variations to the present application without departing from the spirit and scope of the present application. Thus, if these modifications and variations of the present application fall within the scope of the claims of the present application and their equivalents, the present application also intends to include these modifications and variations.
