[0031] The battery cover assembly 1 comprises a battery cover 14, the inner wall of the battery cover 14 is provided with a sliding groove 15, and a battery cover lock buckle 31 and a battery cover buckle 32 are slidably connected to the sliding groove 15;

[0032] A plug 321 is provided at one end of the battery cover buckle 32, and a telescopic opening 142 is opened at one end of the battery cover 14 close to the sliding groove 15, and the plug 321 is slidably connected with the telescopic opening 142; a battery cover locking piece 34 is installed on the battery cover lock buckle 31 for limiting the battery cover buckle 32.

[0033] Furthermore, a battery cover spring 33 is provided on one side of the battery cover lock 31 and the battery cover buckle 32, and the battery cover spring 33 is fixedly connected to the sliding groove 15, and is used to limit the battery cover lock 31 and the battery cover buckle 32;

[0034] Furthermore, the sliding slot 15 has two sliding openings at the upper and lower parts, and one side of the battery cover lock buckle 31 and the battery cover buckle 32 are both arranged corresponding to the sliding openings of the sliding slot 15 .

[0035] Furthermore, a slide button is fixedly provided on one side of the battery cover lock buckle 31 and the battery cover buckle 32 , and the slide button is located in a corresponding slide opening of the slide slot 15 .

[0036] Furthermore, the battery cover lock buckle 31 and the battery cover buckle 32 may be provided with a boss, so that when the battery cover lock buckle 31 and the battery cover buckle 32 are slid, they abut against the battery cover spring leaf 33 to provide a damping feeling, thereby improving the operating feel.

[0037] Furthermore, a first positioning column 141 is provided on the inner wall of the battery cover 14, and a second positioning column 311 is provided on one side of the battery cover lock buckle 31; a rotation hole 342 is provided at one end of the battery cover lock piece 34, and a guide slot 341 is provided through the battery cover lock piece 34; the rotation hole 342 is rotatably connected to the first positioning column 141, and the guide slot 341 is slidably connected to the second positioning column 311.

[0038] Furthermore, a protrusion 343 is provided at one end of the battery cover locking piece 34 away from the rotating hole 342 for abutting against the battery cover buckle 32 for limiting the position.

[0039] When the battery cover lock buckle 31 is pushed, the second positioning column 311 of the battery cover lock buckle 31 moves and slides on the guide slide groove 341 , thereby driving the battery cover lock piece 34 to rotate around the first positioning column 141 .

[0040] Furthermore, a battery compartment 21 is provided on one side of the whole housing 2 , and a card slot 22 is provided at one end of the battery compartment 21 for inserting a plug 321 for card connection.

When the battery cover assembly 1 needs to be closed, the battery cover buckle 32 is first pushed to insert the plug 321 into the card slot 22 to achieve the card connection. Then, the battery cover lock buckle 31 is pushed to make the second positioning column 311 of the battery cover lock buckle 31 drive the battery cover lock piece 34 to rotate around the first positioning column 141, so that the protrusion 343 of the battery cover lock piece 34 abuts the battery cover buckle 32, thereby limiting the movement of the battery cover buckle 32, achieving double locking, and improving the protection of the battery. It is not easy to fail when the machine is shaken or impacted.

[0042] Similarly, when opening the battery cover 14 , the battery cover lock buckle 31 must first be slid to an unlocked state, and then the battery cover buckle 32 must be slid to open the battery cover 14 .

[0044] Furthermore, a waterproof pad 18 is fixed to one side of the cover plate 17 close to the entire housing 2 .

[0045] Through the cooperation of the waterproof pad 18, when the battery cover assembly 1 is closed, the cover plate 17 can be tightly connected to the entire machine housing 2 through the waterproof pad 18, which can effectively isolate the outside of the battery cover 14 and the battery compartment 21, and has a certain waterproof ability.

[0046] Furthermore, the shaft structure includes a battery cover shaft fixing block 11, the battery cover shaft fixing block 11 is fixedly connected to one side of the whole machine housing 2, one end of the battery cover 14 is fixedly connected to a shaft 13, the shaft 13 is rotatably connected to the battery cover shaft fixing block 11, a torsion spring 12 is sleeved on the shaft 13, and the torsion spring 12 is respectively connected to the battery cover shaft fixing block 11 and the battery cover 14.

[0047] The automatic pop-up function of the battery cover 14 is realized by the torsion spring 12. After the two ends of the torsion spring 12 are respectively inserted into the battery cover shaft fixing block 11 and the battery cover 14, the torsion spring 12 has prestressed force. When the battery cover 14 is in the closed state, the torsion spring 12 is twisted and deformed. When the battery cover 14 is opened, the torsion spring 12 returns to its original state and pops up the battery cover 14, thereby realizing the automatic pop-up function of the battery cover 14.

[0048] The battery cover assembly 1 of the utility model realizes the automatic pop-up function of the battery cover assembly 1 through the cooperation of the torsion spring 12 and the battery cover shaft fixing block 11, so that the battery cover assembly 1 can be conveniently opened and closed.
