DETAILED DESCRIPTION

[0022] The utility model is further described in detail below in conjunction with the accompanying drawings.

[0023] Example:

[0024] Reference Figure 1 - Figure 4 The utility model discloses a conveniently disassembled new energy battery cover, comprising a battery box 1 and a cover 2, the cover 2 is placed at the opening of the battery box 1, two opposite side walls of the cover 2 are provided with slide grooves 3, a card block 4 is slidably connected in the slide groove 3, a circular groove 5 is provided at the center of the top of the cover 2, and a knob 6 is rotatably connected thereto, the knob 6 and the card block 4 are connected by an elastic member 7, two electrode columns 8 are symmetrically arranged on the top of the cover 2 with the knob 6 as the reference center, and a card slot for inserting the card block 4 is provided on the inner side wall of the battery box 1.

[0025] In this embodiment, when it is needed, the new energy battery is first loaded into the battery box 1, and then the cover 2 is covered, and the electrode column 8 of the cover 2 is made to contact with the new energy battery, and then the knob 6 is rotated, and the knob 6 moves with the elastic member 7. Under the push of the elastic member 7, the card block 4 extends out of the slide slot 3 and is inserted into the card slot of the battery box 1, completing the installation of the cover 2.

[0026] When the cover 2 needs to be removed, it is only necessary to reverse the knob 6, and then the elastic member 7, driven by the knob 6, pulls the block 4 back into the slide groove 3, thereby disconnecting the cover 2 from the battery box 1. The cover 2 can then be easily removed, allowing the cover 2 to be quickly and flexibly removed with one hand.

[0027] In a further preferred embodiment of the present invention, Figure 2 and Figure 3 As shown, the elastic member 7 includes a push block 71, a connecting rod 72 and a supporting spring 73. A groove 9 is provided on the side of the clamping block 4 close to the knob 6 and is slidably connected to the push block 71. A supporting spring 73 is provided between the push block 71 and the groove 9. A connecting rod 72 is hinged on the side of the push block 71 close to the knob 6, and the end of the connecting rod 72 away from the push block 71 is hinged to the knob 6.

[0028] In this embodiment, when the knob 6 rotates, the connecting rod 72 hinged to the knob 6 will move under the push of the knob 6, and then the connecting rod 72 will push the push block 71 to slide in the groove 9, so that the push block 71 squeezes the support spring 73, and then the support spring 73 pushes the card block 4 to slide out of the slide groove 3 to realize the card connection between the cover 2 and the battery box 1.

[0029] In a further preferred embodiment of the present invention, Figure 2 and Figure 3 As shown, the diameter of the inner bottom wall of the circular groove 5 is larger than the diameter of the knob 6, so that a gap is left between the bottom of the inner wall of the circular groove 5 and the outer wall of the knob 6 for avoiding the hinge point.

[0030] In this embodiment, because the connecting rod 72 is hinged to the knob 6, and the knob 6 needs to rotate to drive the connecting rod 72 to push the block 4 out of the slide groove, in order to avoid the connecting rod 72 from contacting and squeezing the inner wall of the circular groove 5 when the knob 6 is rotated, thereby colliding and interfering with the rotation of the knob 6, the bottom diameter of the inner wall of the circular groove 5 is made larger than the diameter of the knob 6, thereby reserving a gap between the bottom of the circular groove 5 and the knob 6 to avoid the hinge point.

[0031] In a further preferred embodiment of the present invention, Figure 2 and Figure 3 As shown, two stoppers 10 are arranged in a circular array at the bottom of the inner wall of the circular groove 5 , and the two stoppers 10 are respectively arranged at one side of the circular groove 5 close to the clamping block 4 .

[0032] In this embodiment, because a gap is provided at the bottom of the circular groove 5 for avoiding the hinge point between the knob 6 and the connecting rod 72, so that the block 4 can be completely retracted into the slide groove 3, when the knob 6 is rotated too much, the block 4 will first extend out and then retract into the slide groove 3, thereby affecting the connection stability between the cover plate 2 and the battery box 1. Therefore, two blocks 10 are provided in a circular array at the bottom of the inner wall of the circular groove 5, and each block 10 is close to the block 4 at the corresponding position, so that when the knob 6 is rotated too much, it will be blocked by the block 10, preventing the knob 6 from continuing to rotate, so that the block 4 remains extended out of the slide groove 3, so that the cover plate 2 can be stably connected to the battery box 1.

[0033] In a further preferred embodiment of the present invention, Figure 2 and Figure 3 As shown, the outer wall of the clamping block 4 is protruded to form a limiting portion 11 , and a compression spring 12 is arranged between the side of the limiting portion 11 away from the knob 6 and the sliding groove 3 .

[0034] In this embodiment, the compression spring 12 is provided to push the clamping block 4 to return to its original position, so that the clamping block 4 is retracted into the sliding groove 3 , so that the cover plate 2 can be quickly separated from the battery box 1 .

[0035] In a further preferred embodiment of the present invention, Figure 4 As shown, the middle portion of the electrode column 8 is raised in the horizontal direction to form a U-shaped portion 13 that avoids the sliding groove 3.

[0036] In this embodiment, since a slide groove 3 is provided in the cover plate 2, and the electrode column 8 needs to pass through the cover plate 2 to contact the electrode of the new energy battery, in order to prevent the electrode column 8 from passing directly through the slide groove 3 and affecting the movement of the connecting rod 72, a U-shaped portion 13 for avoiding the slide groove 3 is provided in the middle of the electrode column 8, so that the electrode column 8 can ensure contact with the new energy battery without interfering with the connection between the cover plate 2 and the battery box 1.

[0037] The embodiments of this specific implementation method are all preferred embodiments of the utility model, and are not intended to limit the protection scope of the utility model. Therefore, all equivalent changes made based on the structure, shape, and principle of the utility model should be included in the protection scope of the utility model.
