DETAILED DESCRIPTION

[0021] In order to facilitate the understanding of those skilled in the art, the present invention is further described below in conjunction with the embodiments and drawings, and the contents mentioned in the implementation modes are not intended to limit the present invention. The present invention is described in detail below in conjunction with the drawings.

[0022] See also Figure 1-4A battery mounting seat with self-adaptive pressure is specifically implemented, comprising a first mounting seat 1, a second mounting seat 2 and a battery core assembly 4 arranged between the first mounting seat 1 and the second mounting seat 2, a first clamping protrusion 11 is arranged on the side wall of the first mounting seat 1, a second clamping protrusion 12 is arranged on the side wall of the second mounting seat 2, a fastening screw 3 is arranged between the first clamping protrusion 11 and the second clamping protrusion 12, one end of the fastening screw 3 is rotatably arranged in the middle of the first clamping protrusion 11, and the other end of the fastening screw 3 is threadedly connected with the middle of the second clamping protrusion 12, and the fastening screw 3 is fastened to the battery mounting seat 11. The threaded member 3 includes a rotating sleeve 31 and a screw member 32. The rotating sleeve 31 can be movably mounted on one end of the screw member 32 close to the first clamping protrusion 11. An elastic member is provided between the rotating sleeve 31 and the screw member 32 for movably connecting them. The rotating sleeve 31 is a cylindrical structure. The interior of the rotating sleeve 31 is a clutch inner cavity 311 opened to one side of the screw member 32. One end of the screw member 32 provided with a ratchet structure is movably arranged in the clutch inner cavity 311 through an elastic member. The end of the screw member 32 is meshed and transmitted with the rotating sleeve 31 through the ratchet structure.

[0023] By threading the screw member 32 and the second clamping protrusion 12, the second mounting seat 2 between the first mounting seat 1 can be closed and locked with each other, and the second mounting seat 2 between the first mounting seat 1 can be moved to a pressure gap suitable for the battery size. The transmission between the rotating sleeve 31 and the screw member 32 can be interrupted by the ratchet structure and the elastic member, thereby preventing the rotating sleeve 31 from continuing to provide rotational driving force to the screw member 32, thereby achieving the effect of pressure adaptation interruption, and effectively providing pressure protection for the battery components inside the battery mounting seat.

[0024] The specific structure of the ratchet is as follows Figure 3-4 As shown, the ratchet structure includes a first end face ratchet portion 312 and a second end face ratchet portion 321. The first end face ratchet portion 312 is arranged on the inner end face of the rotating sleeve 31, and the second end face ratchet portion 321 is arranged on the end of the screw member 32. The rotating sleeve 31 and the screw member 32 are meshed and transmitted through the first end face ratchet portion 312 and the second end face ratchet portion 321.

[0025] Between the screw member 32 and the first clamping protrusion 11 and the second clamping protrusion 12, the end of the screw member 32 away from the second end face ratchet portion 321 is a threaded portion 323, and the middle part of the second clamping protrusion 12 is provided with a threaded hole matching the threaded portion 323. The screw member 32 is threadedly connected with the threaded hole of the second clamping protrusion 12 through the threaded portion 323. Between the threaded portion 323 and the second end face ratchet portion 321 is a smooth rod portion 322. The screw member 32 is rotatably arranged in the middle part of the first clamping protrusion 11 through the smooth rod portion 322. The elastic member is composed of a spring 33, and the spring 33 is sleeved on the surface of the smooth rod portion 322.

[0026] A limit baffle 43 is further provided at one end of the rotating sleeve 31 away from the first end face ratchet part 312, and a clearance hole 341 is opened in the center of the limit baffle 43. The light rod part 322 is plugged into the clearance hole 341 of the limit baffle 43, and one end of the spring 33 abuts against the second end face ratchet, and the other end of the spring 33 abuts against the limit baffle 43. When the first mounting seat 1 and the second mounting seat 2 are locked, the spring 33 provides an elastic stress between the limit baffle 43 and the second end face ratchet, and the second end face ratchet is pressed toward one side of the first end face ratchet part 312 in the rotating sleeve 31, so that the second end face ratchet and the first end face ratchet part 312 are tightly meshed, and the rotation output force of the rotating sleeve 31 can be transmitted to the screw member 32.

[0027] The process of using a battery mounting seat with self-adaptive pressure is as follows: the battery cell assembly 4 is respectively embedded in the first mounting seat 1 and the second mounting seat 2, and then the second clamping protrusion 12 is aligned with the threaded portion 323 of the screw member 32, and the spring 33 is located between the limit baffle 43 and the second end face ratchet to provide an elastic stress, and the second end face ratchet is squeezed to one side of the first end face ratchet portion 312 in the rotating sleeve 31, so that the second end face ratchet and the first end face ratchet portion 312 are tightly meshed, and then the rotating sleeve 31 is rotated to drive the screw member 32 located in the middle of the first clamping protrusion 11 to rotate, and the screw member 32 is aligned with the second clamping protrusion 11. The threaded engagement between the holding protrusions 12 is performed to tighten the gap between the first mounting seat 1 and the second mounting seat 2. When the first mounting seat 1 and the second mounting seat 2 are tightened to a pressure gap suitable for the length of the battery, the screw member 32 can remain in a stopped state. When the rotating sleeve 31 continues to rotate, the first end face ratchet portion 312 can withdraw along the oblique tooth direction of the second end face ratchet portion 321, so that the transmission between the rotating sleeve 31 and the screw member 32 is interrupted, and the rotating sleeve 31 is prevented from continuing to provide a rotational driving force to the screw member 32, which has the effect of interrupting the pressure adaptation and effectively protecting the battery components inside the battery mounting seat from pressure.
