[0024] like Figure 1-5 As shown, it is a structural schematic diagram of a Bluetooth smart door lock with a protective structure in a preferred embodiment of the utility model;

[0025] In this embodiment, it includes a lock body 1 and a protective cover 2 slidably installed on the top of the front end of the lock body 1. A touch keyboard 3 is provided on the top of the front end of the lock body 1. Slide rails 4 are provided on both sides of the touch keyboard 3. The inner wall surfaces on both sides of the protective cover 2 are provided with slide grooves 5 used to cooperate with the slide rails 4. The slide rails 4 are slidably connected with the slide grooves 5. The protective cover 2 realizes linear reciprocating sliding in the vertical direction through the cooperation of the slide grooves 5 and the slide rails 4. A fixed block 6 is provided on the top of the touch keyboard 3. A gear 7 is rotatably provided on the fixed block 6. A torsion spring 8 is provided between the gear 7 and the fixed block 6. The torsion spring 8 provides torque or rotational force to the gear 7. When the gear 7 rotates clockwise or counterclockwise, the torsion spring 8 is tightened. When the torsion spring 8 is elastically reset, it drives the gear 7 to rotate clockwise or counterclockwise. The needle rotates to reset, the rear end of the protective cover 2 is integrally provided with a rack 9, and the rack 9 is meshed with the gear 7. When the rack 9 moves up and down, the gear 7 can be driven to rotate clockwise and counterclockwise. Conversely, when the gear 7 rotates clockwise and counterclockwise, the rack 9 can be driven to move up and down. The front end of the lock body 1 is located at the bottom of the touch keyboard 3 and is provided with a sliding hole 10. The sliding hole 10 is a circular hole. A through hole 11 is penetrated at the top of the sliding hole 10. A push block 12 is slidably provided in the sliding hole 10. A buckle 13 is provided on the top of the push block 12. A spring 14 is provided in the sliding hole 10. A card slot 15 is provided at the bottom of the rear end of the protective cover 2. The buckle 13 is inserted into the through hole 11 and snapped into the card slot 15. The protective cover 2 is fixed by this structure.

[0026] In this embodiment, a fingerprint collection area 16 is provided at the bottom of the touch keyboard 3, and the fingerprint collection area 16 is used for fingerprint collection and unlocking.

[0027] In this embodiment, two ends of the spring 14 respectively abut against the sliding hole 10 and the push block 12 , and the spring 14 provides elastic force to the push block 12 , so that the push block 12 can automatically pop out and reset.

[0028] In this embodiment, the two ends of the torsion spring 8 are respectively engaged with the fixed block 6 and the gear 7, so that the two ends of the torsion spring 8 are respectively fixedly connected with the fixed block 6 and the gear 7. When the gear 7 rotates around the center of the torsion spring 8, the torsion spring 8 pulls the gear 7 back to the initial position, generating torque or rotational force.

[0029] Principle of this utility model:

[0030] When in use, the push block 12 is pushed to make the buckle 13 disengage from the slot 15, and the gear 7 rotates under the drive of the torsion spring 8, driving the rack 9 to move upward, thereby making the protective cover 2 slide upward and open, and the touch keyboard 3 and the fingerprint collection area 16 can be operated. When the operation is completed, the protective cover 2 is slid downward, the rack 9 drives the gear 7 to rotate and tightens the torsion spring 8, and the buckle 13 is snapped into the slot 15 to fix the protective cover 2, thereby achieving the purpose of covering and protecting the touch keyboard 3 and the fingerprint collection area 16.

[0031] The utility model provides a Bluetooth smart door lock with a protective structure, and its installation method, connection method or setting method are all common mechanical methods, and any method that can achieve its beneficial effects can be implemented.

[0032] Technologies not described in detail in the present invention are all well-known technologies. Those skilled in the art can easily implement the present invention based on understanding this specification, and the contents shown in the drawings are part of this specification.

[0033] The above content is a further detailed description of the utility model in combination with specific implementation methods. It cannot be determined that the specific implementation of the utility model is limited to these descriptions. For ordinary technicians in the technical field to which the utility model belongs, without departing from the concept of the utility model, they can also make several simple deductions or substitutions, which should be regarded as belonging to the scope of protection determined by the claims submitted for the utility model.
