Description

Technical Field

[0001] This utility model relates to a power supply connection structure for an intelligent door lock. Background Technology

[0002] Currently, most smart door locks on the market are powered by lithium batteries. Therefore, users need to replace the batteries when the smart door lock issues a low battery alarm. The battery box is usually located on the side of the smart door lock. When replacing the batteries, users need to pull out the battery box. The battery box is connected to a power supply cable. Therefore, when users pull out the battery box, they may pull on the power supply cable, causing the power supply cable to detach from the battery box.

[0003] Therefore, it is necessary to make further improvements. Utility Model Content

[0004] The purpose of this invention is to overcome the above-mentioned problems and provide a power supply connection structure for a smart door lock. This power supply connection structure can avoid pulling the power supply wire when replacing the battery.

[0005] To achieve the above objectives, this utility model provides a power supply connection structure for a smart door lock, which includes a lock shell and a battery box. The lock shell has a mounting cavity for installing the battery box, and the shell wall of the lock shell has an installation port for the battery box to enter the mounting cavity. The outer side of the battery box is provided with a first contact conductive structure. The mounting cavity is provided with a power board assembly on the side corresponding to the first contact conductive structure. The power board assembly is provided with a second contact conductive structure, and the second contact conductive structure is in contact with the first contact conductive structure for conduction.

[0006] In one or more embodiments, the mounting port is located on the top wall of the lock housing, and the bottom of the battery box is connected to the bottom of the mounting cavity via a push-button self-locking switch.

[0007] In one or more embodiments, the push-to-lock switch includes a hook and a movable claw, the hook being located at the bottom of the battery compartment and the movable claw being located at the bottom of the mounting cavity.

[0008] In one or more embodiments, the first contact conductive structure includes a first contact and a second contact, and the second contact conductive structure includes a first conductive spring and a second conductive spring, wherein the first conductive spring corresponds to the first contact and the second conductive spring corresponds to the second contact.

[0009] In one or more embodiments, the top of the battery box is provided with a decorative panel, the size of which matches the mounting opening, and the upper surface of the decorative panel is flush with the edge of the mounting opening.

[0010] In one or more embodiments, the mounting cavity has a protrusion on its side wall, and the outer wall of the battery box has a groove corresponding to the position of the protrusion.

[0011] In one or more embodiments, the battery box has one or two battery mounting positions adapted for mounting 18650 lithium batteries.

[0012] Compared with the prior art, the advantages of this utility model are: the battery box does not use a power supply to maintain a power supply connection with the smart door lock, but uses a contact conductive method to connect to the power supply. The advantage is that the battery box is not constrained by the power supply after it is detached from the smart door lock, and there is no need to worry about the power supply wire being torn off.

[0015] To enhance understanding of this utility model, the present utility model will be further described in detail below with reference to the embodiments and accompanying drawings. These embodiments are only used to explain the present utility model and do not constitute a limitation on the scope of protection of the present utility model.

[0016] Please refer to the appendix. Figure 1-2 This application provides a power supply connection structure for a smart door lock, which includes a lock housing 1 and a battery box 2. The lock housing has an installation cavity 3 for installing the battery box 2. The lock housing 1 has an installation port 4 on its shell wall for the battery box to enter the installation cavity. The outer side of the battery box 2 is provided with a first contact conductive structure. The side of the installation cavity 3 corresponding to the first contact conductive structure is provided with a power board assembly 5. The power board assembly is provided with a second contact conductive structure. The second contact conductive structure is in contact with the first contact conductive structure and conducts electricity. The battery box and the smart door lock adopt a contact power supply method. The installation and removal of the battery box are no longer affected by the length of the power supply wire, and users do not need to worry about breaking the power supply wire when removing the battery box.

[0017] The mounting port 4 is located on the top wall of the lock housing 1. The bottom of the battery box 2 is connected to the bottom of the mounting cavity 3 via a push-type self-locking switch. By setting the mounting port on the top wall of the lock housing, the gap between the battery box and the mounting port can be avoided in easily observable places such as the side of the lock housing, thus improving the aesthetics of the smart door lock.

[0018] The push-button self-locking switch includes a hook 6 and a movable claw 7. The hook is located at the bottom of the battery box 2, and the movable claw is located at the bottom of the mounting cavity 3. The push-button self-locking switch is characterized by locking when pressed once and unlocking when pressed again. For details, please refer to the structure disclosed in CN207724275U.

[0019] The first contact conductive structure includes a first contact 8 and a second contact 9, and the second contact conductive structure includes a first conductive spring 10 and a second conductive spring 11. The first conductive spring 10 corresponds to the first contact 8, and the second conductive spring 11 corresponds to the second contact 9. When the battery box is installed into the mounting cavity, power supply can be turned on.

[0020] The top of the battery box 2 is provided with a decorative panel 21. The size of the decorative panel matches the mounting opening 4, and the upper surface of the decorative panel is flush with the edge of the mounting opening to avoid the decorative panel protruding and affecting the aesthetics.

[0021] The mounting cavity 3 has a protrusion 12 on its side wall, and the outer wall of the battery box has a groove 13 corresponding to the position of the protrusion. The cooperation between the protrusion and the groove forms a foolproof structure, which can prevent the user from installing the battery box backwards.

[0022] The battery box 2 has one or two battery mounting positions, which are adapted to the installation of 18650 lithium batteries. 18650 lithium batteries are a commonly used battery type in overseas markets. Setting the battery mounting positions of the battery box to be adapted to 18650 lithium batteries is more conducive to product promotion.

[0023] The above description is only a preferred embodiment of the present utility model. The protection scope of the present utility model is not limited to the above embodiments. Any equivalent modifications or changes made by those skilled in the art based on the content disclosed in the present utility model should be included in the protection scope recorded in the claims.
