[0024] In the description of the present application, it should be understood that if the terms "upper", "lower", "left", "right" and the like indicate the orientation or positional relationship shown in the drawings, they are only for the convenience of describing the present application and simplifying the description, and do not indicate or imply that the devices or elements referred to must have a particular orientation, be constructed and operated in a particular orientation, therefore the terms describing the positional relationship in the drawings are only used for exemplary illustration, and cannot be understood as a limitation on the present patent, for those skilled in the art, the specific meaning of the above terms can be understood according to the specific circumstances.

[0025] Referring to Figures 1-5 The preferred embodiment provided by the present application is shown in the drawings.

[0026] The cover plate locking and unlocking device comprises an electronic shell 1, a storage cover plate 2, a rotating lock piece 3 and a coin lock piece 4, the electronic shell 1 has a battery compartment for placing a battery piece 5, the storage cover plate 2 is used to cover the battery compartment, the electronic shell 1 has a cover lock groove 11, the inner end of the rotating lock piece 3 is embedded in the cover lock groove 11, and the rotating lock piece 3 is in a locked state or an unlocked state with the electronic shell 1 through the cover lock groove 11; the outer end of the rotating lock piece 3 forms a rotating lock groove, the coin lock piece 4 is used to embed the rotating lock groove, and the coin lock piece 4 is used to control the rotating arrangement of the rotating lock piece 3 relative to the electronic shell 1, and the coin lock piece 4 is used to switch the locked state or the unlocked state.

[0027] When the storage cover plate 2 needs to be disassembled or assembled, the user inserts the coin lock piece 4 into the rotating lock groove, rotates the coin lock piece 4 to drive the rotation of the rotating lock piece 3, switches the locked state and the unlocked state of the rotating lock piece 3 and the electronic shell 1, and switches the locked state and the unlocked state of the storage cover plate 2, so as to facilitate the opening of the battery compartment and the replacement of the battery piece 5, at the same time, the coin lock piece 4 is more interesting and the control is stronger, the participation of children is improved, the hands-on ability of children is improved, and the coin lock piece 4 is used to lock or unlock the storage cover plate 2, which is simple and fast, and children can assemble and disassemble the storage cover plate 2 independently, and the battery piece 5 can be replaced independently.

[0028] The rotating lock groove comprises a main rotating groove 31, and the main rotating groove 31 is arranged in a long strip shape along the radial direction of the rotating lock piece 3, so that the coin lock piece 4 is inserted in the main rotating groove 31, and the rotation of the rotating lock piece 3 is driven by the torsion of the coin lock piece 4.

[0029] Furthermore, the main rotating slot 31 is arranged in an arc-shaped recess in the direction towards the electronic shell 1, and the cross section of the coin locking piece 4 is arranged in a circular shape; in this way, the cooperation effect of the main rotating slot 31 and the coin locking piece 4 is better, and the contact area of the main rotating slot 31 and the coin locking piece 4 is larger, which facilitates the driving of the coin locking piece 4 to the rotating locking piece 3 and saves more labor.

[0030] The main rotating slot 31 has a rotating slot wall arranged in an arc-shaped recess in the direction towards the electronic shell 1, and the outer surface of the coin locking piece 4 is arranged in an arc shape; when the coin locking piece 4 is embedded in the rotating slot, the outer surface of the coin locking piece 4 is arranged in a flat contact with the rotating slot wall; the force area of the rotating slot wall is increased, which facilitates the driving of the coin locking piece 4 to the rotating locking piece 3 and saves more labor.

[0031] The rotating slot includes two secondary rotating slots 32, the two ends of the main rotating slot 31 are respectively arranged in abutment and communication with the inner ends of the two secondary rotating slots 32, the outer ends of the secondary rotating slots 32 are arranged in extension in the radial direction, and the secondary rotating slots 32 are arranged in arc extension; the outer periphery of the coin locking piece 4 forms a plurality of coin locking teeth, each coin locking tooth is arranged in circumferential interval, and the coin locking teeth extend to the secondary rotating slots 32.

[0032] In this way, under the action of the two secondary rotating slots 32, when the coin locking piece 4 is twisted, the resistance and impact force are reduced, the wear of the coin locking piece 4 and the rotating locking piece 3 is reduced, and the service life of the coin locking piece 4 and the rotating locking piece 3 is improved.

[0033] The coin locking piece 4 has two coin limiting blocks arranged in protrusion, and the two coin limiting blocks are arranged in one-to-one correspondence and embedding with the two secondary rotating slots 32; in this way, under the cooperation of the two coin limiting blocks and the two secondary rotating slots 32, the application of the twisting force of the coin locking piece 4 is facilitated, more labor is saved, and the driving of the coin locking piece 4 to the rotating locking piece 3 is facilitated.

[0034] The cover locking slot 11 includes a cover ring slot and two cover limiting blocks 12, the cover ring slot is arranged in a ring shape, the two cover limiting blocks 12 are arranged in correspondence with the cover ring slot, and the two cover limiting blocks 12 are arranged in two-end correspondence; the rotating locking piece 3 includes two rotating locking blocks 33 arranged in two-end correspondence, the rotating locking block 33 includes a long block part and a short block part arranged in abutment, the long block part is movably embedded in the cover ring slot, and the short block part is arranged in direct contact or misalignment with the cover limiting block 12.

[0035] In this way, when the locking bin cover plate 2 needs to be assembled, the rotating locking piece 3 is driven to rotate by the coin locking piece 4 until the short block part is arranged in direct contact with the cover limiting block 12, the cover limiting block 12 limits the short block part from leaving the cover locking slot 11, thereby realizing the locking of the bin cover plate 2; when the bin cover plate 2 needs to be disassembled, the rotating locking piece 3 is driven to rotate by the coin locking piece 4 until the short block part is arranged in misalignment with the cover limiting block 12, the cover limiting block 12 cancels the limiting force on the short block part, the short block part can leave the cover locking slot 11, the separation of the rotating locking piece 3 and the cover locking slot 11 is realized, and the disassembly of the bin cover plate 2 is realized.

[0036] The cover locking slot 11 has a locking portion at the end of the cover ring slot, which is used to be in contact with the long block portion, and the short block portion is in contact with the cover limiting block 12 when the long block portion is in contact with the locking portion.

[0037] In this way, when the user needs to lock, the coin lock 4 is twisted to rotate the lock 3 until the long block portion is in contact with the locking portion, at which time the locking is completed, and the final position of the twist is positioned to facilitate the user to lock the cover plate 2.

[0038] The cover locking slot 11 has two guide locking surfaces 13, which are arranged to gradually extend outward in a direction away from the cover limiting block 12; the lock 3 has two rotating locking surfaces 34, which are arranged to be inclined; when unlocking, the rotating locking surface 34 is in contact with the guide locking surface 13, and the guide locking surface 13 is used to drive the lock 3 to move away from the electronic shell 1.

[0039] In this way, when the user changes from the locked state to the unlocked state, under the cooperation of the rotating locking surface 34 and the guide locking surface 13, the lock 3 gradually moves outward during rotation, which facilitates the removal of the lock 3 and the unlocking of the cover plate 2, thereby facilitating the operation of children and the replacement of the battery 5.
