Description

Technical Field

[0001] This utility model relates to an electronic lock power supply module. Background Technology

[0002] Existing electronic lock products have built-in battery modules to power their control board and motor. A common structure involves placing the battery pack and power board within the lock body. This not only increases the difficulty of molding the lock body but also requires individually attaching the battery pack and battery cover to the lock body, making the process cumbersome. Therefore, it is essential to use independently detachable power supply modules in battery locks.

[0003] When designing the power supply module, the preferred approach is to use a module shell to enclose the battery pack. However, since the edges of the battery pack are easily damaged by the pressure of the module shell during installation, posing a safety hazard, a guide and limiting structure for the battery pack also needs to be considered. Utility Model Content

[0004] The purpose of this utility model is to provide an electronic lock power supply module, including a module shell and a battery pack and power board placed inside the module shell. The power board is provided with a plug-in terminal for external power supply and a charging interface for external power supply. The module shell includes an upper cover and a lower cover that are interlocked. The upper cover or the lower cover is provided with a baffle for limiting the position of the battery pack. The baffle is located inside the cover edge of the upper cover or the lower cover and extends out of the cover edge, thereby binding the edge of the battery pack to the inner area of ​​the baffle.

[0005] Preferably, the portion of the baffle extending beyond the cover edge includes a first stop portion and a second stop portion disposed at the corner of the cover edge, the first stop portion and the second stop portion being connected to surround the corner of the battery pack.

[0006] Preferably, the baffle is disposed on the lower cover and extends toward the upper cover, and the inner wall of the upper cover is provided with a fitting position adapted to the first stop part and the second stop part, and the first stop part and the second stop part are inserted into the fitting position until their top end abuts against the bottom of the fitting position.

[0007] Preferably, the power board is installed at one end of the module housing, and correspondingly, the upper cover and / or lower cover are provided with a snap-fit ​​seat for snapping and fixing the power board. The plug-in terminal and the charging interface are located between the power board and the end of the module housing, and the module housing has windows for exposing the plug-in terminal and the charging interface, respectively.

[0008] Preferably, the upper or lower cover has a welding edge for ultrasonic welding along its edge, the welding edge extending outward from the inside of the cover edge, and the welding edge has a plurality of spaced protrusions.

[0009] Preferably, the edge of the upper or lower cover is provided with an outwardly protruding connecting body, which is used to fix the electronic lock housing during installation.

[0010] Compared with the prior art, the advantages of this utility model include at least the following:

[0011] 1) The independently detachable power supply module not only reduces the difficulty of molding the lock body shell, but also eliminates the tedious process of gluing the battery pack and battery protective cover to the lock body shell one by one, improving the product assembly efficiency and facilitating disassembly and assembly during daily maintenance.

[0012] 2) A baffle is provided at the edge of the cover to restrain the edge of the battery pack, so as to protect the edge of the battery pack from being pressed during the pressing of the upper and lower covers; at the same time, the baffle extends outward from the edge of the cover and plays a guiding and positioning role in the pressing of the upper and lower covers.

[0019] The following description, in conjunction with the accompanying drawings, further illustrates the proposed solution:

[0020] See appendix Figures 1 to 5 An electronic lock power supply module includes a module housing 1, a battery pack 2 and a power board 3 placed inside the module housing 1. The power board 3 is provided with a plug-in terminal 31 for external power supply and a charging interface 32 for external power supply. The module housing 1 includes an upper cover 11 and a lower cover 12 that are interlocked. The upper cover 11 or the lower cover 12 is provided with a baffle 13 for limiting the battery pack 2. The baffle 13 is located inside the cover edge of the upper cover 11 or the lower cover 12 and extends out of the cover edge to bind the edge of the battery pack 2 to the inner area of ​​the baffle 13.

[0021] This invention realizes an independently detachable power supply module, which not only reduces the difficulty of molding the lock body shell, but also eliminates the tedious process of gluing the battery pack and battery protective cover to the lock body shell one by one, improving the product assembly efficiency and facilitating disassembly and assembly during daily maintenance. Furthermore, a baffle is provided at the edge of the cover to restrain the edge of the battery pack, protecting the edge of the battery pack from being pressed during the pressing of the upper and lower covers; simultaneously, the baffle extends outward from the edge of the cover, providing a guiding and positioning function for the pressing of the upper and lower covers.

[0022] Specifically, the upper cover 11 has a protruding connecting body 14 on its edge. The connecting body 14 is used to fix the electronic lock housing during installation, for example, by inserting it into a slot. The baffle 13 is located on the lower cover 12 and extends toward the upper cover 11. The portion of the baffle 13 extending beyond the cover edge includes a first stop portion 131 and a second stop portion 132 located at the corner of the cover edge. The first stop portion 131 and the second stop portion 132 are connected to surround the corner of the battery pack 2. Correspondingly, the inner wall of the upper cover 11 has a fitting position 15 adapted to the first stop portion 131 and the second stop portion 132. The first stop portion 131 and the second stop portion 132 pass through the fitting position 15 until their top ends abut against the bottom of the fitting position 15.

[0023] See appendix Figure 6 To facilitate better guidance during assembly, the outer edges of the first stop portion 131 and the second stop portion 132 are inclined, and the interlocking position 15 is provided with an overlapping edge 151 that matches the inclined outer edges of the first stop portion 131 and the second stop portion 132, thereby making the opening of the interlocking position 15 slightly wider, so as to facilitate the insertion of the top ends of the first stop portion 131 and the second stop portion 132 and guide them by the overlapping edge 15. As for the angle of inclination, it depends on the actual production requirements.

[0024] The power board 3 is mounted on one end of the module housing 1. The upper cover 11 and lower cover 12 each have a locking seat 16 for securing the power board 3. The plug-in terminal 31 and charging interface 32 are located between the power board 3 and the end of the module housing 1. The module housing 1 has windows on it for exposing the plug-in terminal 31 and charging interface 32. Preferably, the charging interface 32 is a USB interface to facilitate charging of the battery pack 2.

[0025] The upper cover 11 and the lower cover 12 are connected by ultrasonic welding. In this embodiment, the upper cover 11 has a welding edge 17 for ultrasonic welding along its edge. The welding edge 17 extends outward from the inside of the edge. The welding edge 17 is distributed on each side of the edge and avoids corners to avoid conflict with the position of the baffle 13. Each side of the edge includes at least two mutually isolated welding edges 17. The welding edge 17 has multiple spaced protrusions 171 to improve the ultrasonic welding effect and make the connection more uniform and firm.

[0026] The above preferred embodiments should be regarded as illustrative examples of the embodiments of the present application. Any technical deductions, substitutions, improvements, etc. that are similar to or based on the present application should be considered within the scope of protection of this patent.
