[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0022] The utility model provides a fully automatic compensating transmission door lock, such as Figure 1-Figure 5 As shown, it includes an inner lock shell 1 and an outer lock shell 2, and a transmission assembly 3 is installed between the inner lock shell 1 and the outer lock shell 2. The transmission assembly 3 includes a motor 33, a primary transmission gear 31 and a secondary transmission gear 32. An elastic compensation member 34 is arranged between the primary transmission gear 31 and the secondary transmission gear 32. A baffle 35 is installed on the outer side of the elastic compensation member 34. The elastic compensation member 34 is an annular structure. Connecting rods 341 are installed at both ends of the elastic compensation member 34. A driven tooth 36 is rotatably connected to one side of the primary transmission gear 31, and the secondary transmission gear 32 is meshed with the driven tooth 36. The elastic compensation member 34 connects the driven tooth 36 with the primary transmission gear 31. The rotation of the primary transmission gear 31 can drive the driven tooth 36 to rotate through the elastic compensation member 34, thereby driving the secondary transmission gear 32 to rotate. Specifically, when the motor 33 drives the primary transmission gear 31 to rotate, the primary transmission gear 31 will not directly and rigidly mesh with the secondary transmission gear 32, but indirectly drive the secondary transmission gear 32 through the connection between the elastic compensation member 34 and the driven tooth 36. During this process, if the rotational resistance of the lock core is encountered, the elastic compensating member 34 can be deformed to absorb and disperse part of the impact force, thereby protecting the transmission system from rigid impact.
[0023] At the same time, due to the presence of the elastic compensation member 34, when the lock core needs to be precisely positioned, it can push the driven tooth 36 and the secondary transmission gear 32 through its own deformation recovery force, so that it can reach the predetermined position more accurately. In this way, not only the positioning accuracy of the lock core is improved, but also the risk of jamming or overload damage caused by rigid transmission is reduced.
[0024] In addition, the design of the door lock also takes convenience and safety into consideration. The inner lock housing 1 is provided with an inner panel 11 and an inner lock handle 111 connected thereto, which facilitates the user to unlock the door from indoors. The unlocking panel 23 on the outer lock housing 2 is used for unlocking the door outdoors, and can be controlled by password, fingerprint, card swiping, etc., which improves the safety of the door lock.
[0025] In this embodiment, an inner panel 11 is installed on the outer wall of the inner lock housing 1 for decorating the inner lock housing 1 .
[0026] Specifically, an inner mounting plate 12 is installed on the inner side of the inner lock housing 1, and the inner mounting plate 12 is fixed on the inner side of the door. An outer mounting plate 21 is installed on the inner side of the outer lock housing 2, and the outer mounting plate 21 is fixed on the outer side of the door.
[0027] Furthermore, a motor mounting hole 22 is provided at the bottom of the outer lock housing 2 , and the base of the motor 33 is fixed at the motor mounting hole 22 , so as to facilitate the installation and fixation of the motor 33 .
[0028] Furthermore, a first through hole 121 is provided on the surface of the inner mounting plate 12, and a second through hole 211 is provided on the surface of the outer mounting plate 21. One end of the lock core transmission member 321 passes through the second through hole 211 and the first through hole 121 in sequence and is connected to the inner lock handle 111 on the inner panel 11.
[0029] Furthermore, a battery compartment 13 is provided in the middle of the inner lock housing 1, and a rechargeable battery is installed in the battery compartment 13 for providing power for the electronic structure of the door lock.
[0030] Furthermore, an unlocking panel 23 is installed on the outer wall of the outer lock housing 2 for installing fingerprint and password components.
[0031] When the fully automatic compensating transmission door lock of the utility model is used, first when the user needs to unlock the door, the fully automatic compensating transmission door lock starts to work. The core part of the door lock, the motor 33 in the transmission assembly 3, receives an unlocking signal, which can come from a variety of sources, such as a password or fingerprint verification entered by the user through the unlocking panel 23.
[0032] Once the verification is passed, the motor 33 starts to drive the primary transmission gear 31 to start rotating. However, unlike the traditional rigid transmission, the design of this door lock cleverly introduces an elastic compensation member 34. When the primary transmission gear 31 rotates, it does not directly mesh with the secondary transmission gear 32, but drives the driven gear 36 connected to it through the elastic compensation member 34.
[0033] The elastic compensating member 34 is designed as an annular structure, and connecting rods 341 are installed at both ends to ensure the stability of the transmission. When encountering the rotation resistance of the lock core, the elastic compensating member 34 will deform, thereby effectively absorbing and dispersing the impact force, preventing the transmission system from being damaged due to rigid impact.
[0034] Under the buffering effect of the elastic compensation member 34, the driven tooth 36 can more smoothly drive the secondary transmission gear 32 to rotate. The lock core transmission member 321 moves accordingly, and one end of it passes through the second through hole 211 of the outer mounting plate 21 and the first through hole 121 of the inner mounting plate 12 in sequence, and finally connects with the inner lock handle 111 on the inner panel 11 to open the lock core.
[0035] At the same time, the presence of the elastic compensating member 34 also ensures the precise positioning of the lock core. When it is necessary to reach the predetermined position, the elastic compensating member 34 will use its own deformation recovery force to accurately push the driven tooth 36 and the secondary transmission gear 32 to the specified position. This not only significantly improves the positioning accuracy of the lock core, but also greatly reduces the risk of jamming or overload damage.
[0036] The whole unlocking process is fast and smooth, which not only ensures the convenience of the user, but also ensures the safety of the door lock through multiple safety designs. The battery compartment 13 in the middle of the inner lock shell 1 provides continuous power support for all this, ensuring the reliable operation of the door lock in various environments.
[0037] Finally, it should be noted that the electronic components in the motor 33 in this embodiment are all universal standard parts or parts known to those skilled in the art, and their structures and principles can be known to those skilled in the art through technical manuals or through conventional experimental methods. In the idle space of this device, all the above-mentioned electrical components are connected by wires respectively. The specific connection means should refer to the working sequence between the electrical components in the above-mentioned working principle to complete the electrical connection, which are all well-known technologies in the art.
[0038] The above shows and describes the basic principle, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only preferred examples of the utility model and are not used to limit the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, which fall within the scope of the utility model to be protected. The scope of protection of the utility model is defined by the attached claims and their equivalents.
