[0024] In order to make the purpose, technical solution and advantages of the present invention more clear, the present invention is further described in detail below in conjunction with specific embodiments and with reference to the accompanying drawings. It should be noted that the embodiments of the present invention and the features therein can be combined with each other unless there is any conflict.

[0025] It should be understood that these descriptions are only exemplary and are not intended to limit the scope of the present invention.

[0026] Some embodiments of the present invention are described below with reference to the accompanying drawings.

[0027] Reference Figures 1-9 , a smart door lock front panel with convenient battery removal, comprising a shell 1, a lock body 2 is installed in the shell 1, an unlocking part 3 is installed on the lower side of the lock body 2 to unlock the lock body 2 when it is rotated, a mounting seat 4 is installed on the lower side of the shell 1 at the lower side of the lock body 2, the lower side of the mounting seat 4 is open, and a battery seat 9 is installed on the lower side of the mounting seat 4 that is popped out by a power spring 10; a mechanical lock core 5 is installed in the mounting seat 4, and the mechanical lock core 5 is equipped with a paddle 6 that rotates synchronously with the key, and the left and right sides of the mechanical lock core 5 are respectively provided with It is equipped with a lock body unlocking member 7 for driving the unlocking part 3 to rotate, which is driven by the paddle 6, and a battery holder unlocking member 8 for fixing the battery holder 9. The lock body unlocking member 7 and the battery holder unlocking member 8 are reset by the first reset spring 11 and the second reset spring 12 respectively. By turning the key in different directions, the door can be opened or the battery holder can be withdrawn. The structure is ingenious, so as to facilitate the disassembly and assembly of the battery. The battery is located on the front door panel of the smart door lock, and the rear panel is a purely mechanical structure. No fireproofing process is required, which reduces production costs.

[0028] Example 1: The unlocking part 3 unlocks the lock body 2 by rotating (which is one of the conventional ways to unlock the lock body). A rack part 13 is provided on the lock body unlocking member 7, and a gear part 14 is provided on the unlocking part 3. The rack part 13 and the gear part 14 are engaged and transmitted. When the paddle 6 moves the lock body unlocking member 7, the rack part 13 drives the unlocking part 3 to rotate through the gear part 14, thereby unlocking the lock body 2. At this time, the door can be opened by turning the handle 25 of the smart door lock.

[0029] Example 2: The unlocking part 3 unlocks the lock body 2 by pushing. A push plate 27 is provided on the lock body unlocking member 7. The push plate 27 abuts against the unlocking part 3. When the paddle 6 pushes the unlocking part 3 through the push plate 27, the unlocking part 3 pushes the unlocking part of the lock body 2 (which is also one of the conventional ways to unlock the lock body), unlocking can be achieved. At this time, the door can be opened by turning the handle 25 of the smart door lock.

[0030] The unlocking portion 3 may be a structure fixed in the lock body 2, or may be a structure integral with the lock body unlocking member 7 (e.g. Figure 7 as shown).

[0031] An extension plate 28 is also provided on the lock body unlocking member 7. When the paddle 6 rotates, the paddle 6 pushes the lock body unlocking member 7 to move through the extension plate 28, reducing the distance between the paddle 6 and the lock body unlocking member 7, and avoiding the paddle 6 or the lock body unlocking member 7 from being too large (if the distance between the lock body unlocking member 7 and the paddle 6 is too large, the size of the paddle 6 or the lock body unlocking member 7 needs to be increased to ensure that the paddle 6 can push the lock body unlocking member 7), affecting the distribution of the internal structure of the door lock.

[0032] A first mounting post 15 is provided on the lock body unlocking member 7 , and a first mounting groove 16 corresponding to the first mounting post 15 is provided on the mounting seat 4 . The first return spring 11 is installed in the first mounting groove 16 , and one end of the first return spring 11 is inserted into the first mounting post 15 .

[0033] The battery holder unlocking member 8 is provided with a hook 17, and the battery holder 9 is provided with a corresponding hook hole 18, and the hook 17 is inserted into the hook hole 18 (the hook hole 18 can be a hole with four closed sides, or a notch structure with three closed sides and one open side, such as Figure 7 As shown), the hook 17 is provided with a chamfer 23. When the battery holder 9 is inserted, the chamfer 23 abuts against the inner wall of the hook hole 18 and pushes the battery holder unlocking piece 8 to move sideways. When the hook 17 is fully inserted into the hook hole 18, the second return spring 12 pushes the battery holder unlocking piece 8 to reset, thereby fixing the battery holder 9. At this time, the power spring 10 cannot eject the battery holder 9. When the paddle 6 pulls the battery holder unlocking piece 8, the hook 17 is disengaged from the hook hole 18, and the power spring 10 directly ejects the battery holder 9.

[0034] A second mounting post 19 is provided on the battery holder unlocking member 8, and a second mounting groove 20 corresponding to the second mounting post 19 is provided on the mounting seat 4. The second return spring 12 is installed in the second mounting groove 20, and one end of the second return spring 12 is inserted into the second mounting post 19.

[0035] A power connection piece 21 is installed above the battery holder 9 in the mounting seat 4. The power connection spring 10 is installed between the power connection piece 21 and the battery holder 9, and the power connection piece 21 is electrically connected to the battery in the battery holder 9 through the power connection spring 10.

[0036] A number of battery chambers for installing batteries are provided in the battery holder 9. Conductive sheets are installed at the ends of the battery chambers to connect all the batteries in series. A power connection part electrically connected to the power connection spring 10 is installed above the battery holder 9. The power connection part and the conductive sheet are electrically connected. This can be achieved by welding wires to the power connection part and the conductive sheet respectively, or by bending the conductive sheet and the power connection part, which are two different components, according to the structure of the battery holder 9 so that they can directly contact to form an electrical connection. It can also be that the conductive sheet and the power connection part are the same component, and after being bent and installed according to the structure of the battery holder 9, the part electrically connected to the power connection spring 10 is the power connection part.

[0037] An insertion part 26 is provided on the mounting seat 4, and the power connection piece 21 is inserted into the insertion part 26.

[0038] An end cover 22 is also installed on the mounting seat 4 to fix the components in the mounting seat 4. Especially when maintenance is required, when the panel 24 of the intelligent door lock needs to be removed, without the end cover 22, during the maintenance process, some or certain components in the mounting seat 4 may pop out, increasing the workload of maintenance. With the end cover 22, the end cover 22 only needs to be removed when maintaining the components in the mounting seat 4.
