Description

Technical Field

[0001] The utility model relates to a lock, in particular to an intelligent door lock. Background Art

[0002] The existing smart door locks generally include two types. One is a smart lock that is directly wired to the household power supply. This smart lock can last forever, but due to the wired structure, it is relatively troublesome to install. The other is a smart lock with its own battery. This smart lock has a built-in rechargeable battery that can achieve self-power supply, but the battery capacity has an upper limit, so it needs to be charged regularly. However, due to the increasing number of functions of existing smart locks, compared with early smart locks (early smart locks generally only have low-energy functions such as unlocking, locking, screen lighting, and screen off), existing smart locks have added more functions, such as monitoring, especially all-weather monitoring, which consumes power particularly quickly. The existing single-battery smart door locks can no longer meet the needs of users, and directly increasing the capacity of the battery on the existing smart door locks will occupy the space for the anti-lock screw, causing it to lose the anti-lock function. Summary of the invention

[0003] In order to overcome the deficiencies of the prior art, the utility model provides an intelligent door lock with a large battery capacity.

[0004] The technical solution adopted by the utility model to solve its technical problems is:

[0005] A smart door lock with a large battery capacity comprises an inner door lock body, an unlocking mechanism is installed in the inner door lock body, a reverse locking device is arranged in the unlocking mechanism, a first battery compartment and a second battery compartment for placing batteries are arranged on the front of the inner door lock body, a reverse locking shaft is installed on the reverse locking device, a first transmission part that rotates synchronously is arranged on the reverse locking shaft, a reverse locking key is installed on the outer sides of the first battery compartment and the second battery compartment in the inner door lock body, a second transmission part is arranged on the reverse locking key corresponding to the first transmission part, and the first transmission part is connected with the second transmission part in transmission.

[0006] The anti-locking key is an anti-locking knob, and the second transmission part and the first transmission part are both gear structures.

[0007] The anti-locking key is an anti-locking slider, the second transmission part is a rack structure, and the first transmission part is a gear structure.

[0008] A plurality of mounting shafts are arranged in the lock body of the inner door lock, and a transmission gear set is rotatably mounted on the mounting shafts. The first transmission part and the second transmission part are transmission-connected via the transmission gear set.

[0009] The anti-locking shaft is integrally formed with the first transmission part.

[0010] The anti-locking key is integrally formed with the second transmission part.

[0011] The beneficial effects of the utility model are as follows: an unlocking mechanism is installed in the inner door lock body, a reverse locking device is arranged in the unlocking mechanism, a first battery compartment and a second battery compartment for placing batteries are arranged on the front side of the inner door lock body, a reverse locking shaft is installed on the reverse locking device, a first transmission part rotating synchronously is arranged on the reverse locking shaft, a reverse locking key is installed on the outer sides of the first battery compartment and the second battery compartment in the inner door lock body, a second transmission part is arranged on the reverse locking key corresponding to the first transmission part, the reverse locking key is moved away from the conventional position through the transmission connection between the first transmission part and the second transmission part, and sufficient space is left for the second battery compartment. At the same time, the battery capacity of the smart door lock is doubled while retaining the reverse locking function. BRIEF DESCRIPTION OF THE DRAWINGS

[0016] In order to make the purpose, technical solution and advantages of the utility model clearer, the utility model is further described in detail below in combination with specific implementation methods and with reference to the accompanying drawings. It should be noted that the embodiments of the utility model and the features in the embodiments can be combined with each other without conflict.

[0017] It should be understood that these descriptions are exemplary only and are not intended to limit the scope of the present invention.

[0018] Some embodiments of the present invention are described below in conjunction with the accompanying drawings.

[0019] Reference Figure 1-3, a smart door lock with large battery capacity, comprises an inner door lock body 1, an unlocking mechanism 2 is installed in the inner door lock body 1, and an anti-locking device is arranged in the unlocking mechanism 2, a first battery compartment 3 and a second battery compartment 4 for placing batteries are arranged on the front of the inner door lock body 1, an anti-locking shaft 5 is installed on the anti-locking device, and a first transmission part 6 that rotates synchronously is arranged on the anti-locking shaft 5, an anti-locking key 7 is installed on the outer side of the first battery compartment 3 and the second battery compartment 4 in the inner door lock body 1, and a second transmission part 8 is arranged on the anti-locking key 7 corresponding to the first transmission part 6, and the anti-locking key is moved from the conventional position through the transmission connection between the first transmission part 6 and the second transmission part 8, leaving enough space for the second battery compartment, and at the same time, on the basis of retaining the anti-locking function, the battery capacity of the smart door lock is doubled. In this embodiment, enough space is left for the second battery compartment 4.

[0020] Embodiment 1: The anti-lock key 7 is an anti-lock knob, and the second transmission part 8 and the first transmission part 6 are both gear structures. By rotating the anti-lock knob, the second transmission part 8 can be synchronously transmitted, and then the anti-lock shaft 5 is rotated through the first transmission part 6. At this time, the anti-lock device makes a corresponding response to lock or release the anti-lock.

[0021] Embodiment 2: The anti-lock key 7 is an anti-lock slider, the second transmission part 8 is a rack structure, and the first transmission part 6 is a gear structure. The rack structure is moved by sliding the anti-lock key 7, and the anti-lock shaft 5 is rotated through the first transmission part 6. At this time, the anti-lock device responds accordingly to lock or release the anti-lock.

[0022] A plurality of mounting shafts 9 are arranged in the inner door lock body 1, and a transmission gear set 10 is rotatably mounted on the mounting shaft 9. The first transmission part 6 and the second transmission part 8 are connected in transmission via the transmission gear set 10. The number of gears in the transmission gear set 10 can be selectively increased or decreased according to the distance between the anti-lock key 7 and the anti-lock shaft 5. For example, in Example 1, the number of gears in the transmission gear set 10 is 1, and in Example 2, the anti-lock key 7 and the anti-lock shaft 5 are directly connected in transmission with the first transmission part 6 via the second transmission part 8.

[0023] The anti-lock shaft 5 is integrally formed with the first transmission part 6, and the anti-lock key 7 is integrally formed with the second transmission part 8, which reduces the number of assembly parts. On the one hand, it is convenient for assembly workers to assemble, and on the other hand, it reduces the pressure of inventory types.

[0024] In the present application, the original anti-lock key of the smart door lock is first removed, but the anti-lock shaft 5 for installing the anti-lock key is retained. Through the corresponding transmission connection, the new anti-lock key is installed at a lower position of the smart door lock, leaving enough space for the opening of the second battery compartment 4. Apart from this, the rest of the structure of the smart door lock is the existing technology.

[0025] In addition, conventional transmission methods such as chain transmission can also be used. In addition, through different transmission designs, the anti-lock key 7 can be installed on the side or bottom of the inner door lock body 1.
