Description

Technical Field

[0001] The utility model relates to a battery compartment cover structure used for rotating opening of a lock body. Background Art

[0002] Prior art, such as Chinese utility model patent document, publication number CN220731708U, discloses a battery compartment cover opening structure of a smart lock, including a shell, a battery compartment cover and a trigger rod assembly, wherein a battery compartment is provided in the shell, the battery compartment cover is detachably connected to the shell, and the battery compartment cover is closed on the battery compartment, a mounting seat is also provided in the shell, the trigger rod assembly is installed in the mounting seat, a trigger block is provided on the battery compartment cover, one side of the trigger rod assembly is a trigger end, the trigger end extends to the outside of the shell, and the other side of the trigger rod assembly is opposite to the trigger block, the trigger end triggers the trigger rod assembly, so that the trigger rod assembly conflicts with the trigger block, thereby lifting the battery compartment cover, and the battery compartment cover is removed from the shell.

[0003] Based on the above, in the prior art, the battery compartment cover is detachably connected to the shell, and then a trigger rod assembly is provided. When opening, the battery compartment cover can be lifted up by pressing the trigger rod assembly to make it contact with the trigger block. The technical problem with this structure is that the battery compartment cover needs to be fixed to the shell by existing connection methods such as snaps, and in order to facilitate opening of the battery compartment cover, a trigger rod assembly is further provided to cooperate with the trigger block. This structural setting makes the overall structure more complicated, with a large number of parts and high production costs. Moreover, in order to achieve that the battery compartment cover can be lifted up by the trigger rod assembly, it must adopt a snap-on structure. As described in the specification of the application, a buckle hook is provided on the shell, and a buckle plate is provided on the battery compartment cover. This snap-on structure makes the overall structure more complicated and is not conducive to production and manufacturing. Utility Model Content

[0020] The utility model is further described below in conjunction with the accompanying drawings and embodiments.

[0021] See also Figure 1-Figure 6 A battery compartment cover structure for a lock body to be opened by rotation, comprising a housing 10, wherein the housing 10 is hollow inside to form a cavity 100 and the rear end face is open, a cover plate 20 is arranged on the rear end face of the housing 10, a battery compartment 110 is arranged in the cavity 100, the cover plate 20 is composed of a face cover 210 and a battery compartment cover 220, the battery compartment cover 220 is arranged corresponding to the battery compartment 110, a rotating shaft 230 is arranged on the battery compartment cover 220, the rotating shaft 230 is rotatably arranged on the housing 10, and an elastic limiting component 30 for limiting the rotation of the rotating shaft 230 is arranged on the housing 10;

[0022] The battery compartment cover 220 rotates relative to the housing 10 with the rotation axis 230 as the rotation axis, so that the battery compartment cover 220 covers the housing 10 at the rear side of the battery compartment 110 or moves from the rear of the battery compartment 110 to the outside of the housing 10 .

[0023] The utility model adopts a rotating opening method. Under the constraint of the elastic limit assembly, the battery compartment cover will not rotate at will. When an external force acts on the battery compartment cover, the battery compartment cover rotates relative to the housing with the rotating shaft as the rotating axis, so that the battery compartment cover moves from the rear of the battery compartment to the outside of the housing to achieve opening. The utility model can not only achieve convenient opening, but also has a simple overall structure, which is conducive to reducing costs.

[0024] See also Figure 4 A plurality of positioning grooves 240 are arranged in a circle along the axis of the rotating shaft 230 on the outer wall thereof, and the elastic limiting component 30 can be embedded in any positioning groove 240 .

[0025] See also Figure 4The elastic limiting component 30 is a spring sheet, which includes a fixing portion 320 and a deformation portion 310 . The fixing portion 320 is fixedly disposed in the housing 10 , and the deformation portion 310 can be embedded in any positioning groove 240 .

[0026] The utility model inserts the deformable part 310 into any one of the positioning grooves 240, which exerts resistance on the rotating shaft 230 so that the rotating shaft 230 does not rotate relative to the fixed sleeve 120 at will. When the battery compartment cover 220 is opened, a rotational force is applied to the battery compartment cover 220 so that the rotating shaft 230 rotates relative to the fixed sleeve 120, causing the deformable part 310 to deform and disengage from the positioning groove 240, and the rotating shaft 230 can then rotate relative to the fixed sleeve 120.

[0027] See also Figure 4 and Figure 6 The housing 10 is provided with a fixed sleeve 120 for rotation, and the rotating shaft 230 is movably inserted in the fixed sleeve 120;

[0028] The fixing sleeve 120 is provided with a slot 121 at a position corresponding to any one of the positioning slots 240 . The fixing portion 320 is fixedly connected to the outer wall of the fixing sleeve 120 . The deformation portion 310 passes through the slot 121 and is embedded into any one of the positioning slots 240 .

[0029] See also Figure 6 The front end surface of the housing 10 is provided with a countersunk hole 130 which is in communication with the fixing sleeve 120, and a connecting bolt 50 which is threadedly connected with the rotating shaft 230 is provided in the countersunk hole 130. The connecting bolt 50 is connected with the rotating shaft 230, and can constrain the front and rear positions of the rotating shaft 230 and the battery compartment cover 220 to prevent the rotating shaft 230 from being separated from the fixing sleeve 120.

[0030] See also Figure 4 The fixing portion 320 is fixed on the fixing sleeve 120 by using a fixing bolt 40 .

[0031] See also Figure 1 and Figure 2 The end surface of the battery compartment cover 220 in contact with the face cover 210 is the first arc surface 221, and the end surface of the face cover 210 in contact with the battery compartment cover 220 is the second arc surface 211. The first arc surface 221 and the second arc surface 211 are located on a circle with the axis of the rotating shaft 230 as a circle. This arrangement can not only make the first arc surface 221 fit with the second arc surface 211, but also can achieve that when the battery compartment cover 220 rotates, it will not interfere with the face cover 210.
