Description

A connection structure between a battery and a circuit board, and a smart lock sticker Technical Field

[0001] This utility model relates to the field of smart lock accessories, specifically to a connection structure between a battery and a circuit board, and a smart lock sticker. Background Technology

[0002] With the rapid development of technologies such as the Internet of Things (IoT), mobile internet, and artificial intelligence (AI), smart locks have been rapidly adopted as part of smart homes. Smart locks not only offer enhanced security but also provide functions such as remote control, automatic unlocking, user access management, and access logging. However, existing smart locks typically require a complete replacement of the original mechanical lock system, which increases costs for users and wastes resources.

[0003] Against this backdrop, smart lock stickers have emerged as an innovative solution. A smart lock sticker is a device specifically designed to connect to a standard mechanical lock cylinder, adding intelligent features without altering the original mechanical lock's structure. By installing a smart lock sticker, users can retain their existing mechanical lock cylinder while enjoying the various conveniences and advanced functions offered by smart locks.

[0004] In existing smart lock stickers, the battery installation method and internal electrical connections are crucial factors affecting product performance and electrical connection reliability, especially the battery installation method. Traditional battery installation methods require multiple wires to connect the battery's positive and negative terminals to different locations on the control circuit board. This segmented connection method not only increases the complexity of the internal structure but also occupies a significant amount of internal space. When replacing the battery, users must accurately distinguish and connect the positive and negative terminals, a process that is very inconvenient for non-professional users, easily leading to misoperation or incorrect connections, increasing the risk of malfunction. Traditional battery installation methods typically require multiple wires to connect the battery's positive and negative terminals to the control circuit board, increasing the complexity of the internal structure and the space occupied. This not only makes the overall size of the smart lock sticker larger but also limits its installation and application within limited spaces.

[0005] Therefore, overcoming the aforementioned defects and providing a battery-circuit board connection structure and intelligent locking mechanism that facilitates stable and accurate installation of batteries and circuit boards while effectively saving connection components and installation space has become an important issue that urgently needs to be addressed by those skilled in the art. Utility Model Content

[0006] This invention overcomes the shortcomings of the above-mentioned technologies and provides a connection structure between a battery and a circuit board, as well as an intelligent locking device.

[0007] To achieve the above objectives, the present invention adopts the following technical solution:

[0008] A connection structure between a battery and a circuit board includes a control circuit board and a battery. The battery is electrically connected to the control circuit board. A positive conductive part and a negative conductive part are provided on one side of the control circuit board. A conductive spring extending vertically upward is connected to the negative conductive part. The conductive spring includes a connecting end, a spring end, and a vertical rod located between the connecting end and the spring end. The connecting end is connected to the negative conductive part. The positive electrode of the battery abuts against the positive conductive part, and the negative electrode of the battery abuts against the spring end. The battery is vertically disposed between the positive conductive part and the spring end.

[0009] Furthermore, the connection end is fixed to the control circuit board by screws.

[0010] Furthermore, the control circuit board has a socket and a USB interface on the side of the board where the positive and negative conductive parts are arranged opposite each other.

[0011] Furthermore, on the other side of the control circuit board where the positive and negative conductive parts are respectively arranged, buttons and LED beads are also provided, and a number of LED beads are arranged at equal intervals along the circumference of the control circuit board.

[0012] Furthermore, the control circuit board is provided with a buzzer and a reset button on the other side of the board surface where the positive and negative conductive parts are arranged opposite each other.

[0013] Furthermore, it also includes a mounting base, on which the control circuit board and battery are connected.

[0014] Furthermore, the side wall of the fixing base is recessed to form a battery receiving cavity for accommodating the battery. There are three batteries and three battery receiving cavities, and three positive conductive parts and three negative conductive parts.

[0015] Furthermore, the inner wall of the battery housing cavity is provided with a first positioning groove for supporting and fixing the vertical rod and a second positioning groove for supporting and fixing the spring end.

[0016] A smart lock includes a battery and circuit board connection structure as described above, and a housing that is circumferentially fixed to a mounting base and rotates synchronously therewith. The mounting base is installed inside the housing. The housing includes a base plate made of a light-transmitting material, and a button for pressing is provided on the outer side of the base plate.

[0017] Compared with the prior art, the beneficial effects of this utility model are:

[0018] This design utilizes a vertically extending conductive spring to place the positive and negative terminals of the control circuit board at the same end. This same-end battery installation reduces the footprint on the internal structure, eliminates cumbersome wiring connections, reduces overall size, and enhances compatibility with various smart locks. Furthermore, it makes it easier for users to distinguish the positive and negative terminals during battery installation, facilitating battery installation and replacement. Traditional battery installation methods often require multiple wires to connect the battery's positive and negative terminals to the control circuit board, increasing assembly difficulty and the risk of failure. The same-end design achieves electrical connection directly through the conductive spring, eliminating the need for additional wires and simplifying the electrical connection process. Users simply insert the battery vertically to complete the installation. Users can easily and intuitively distinguish the required positive and negative terminal orientation, greatly facilitating daily use and maintenance. Especially when multiple batteries need to be installed, installing one battery allows for quick installation of others without needing to re-confirm the polarity. This same-end design makes installation much faster. Attached Figure Description

[0025] The following examples provide a more detailed description of the features and other related characteristics of this utility model, to facilitate understanding by those skilled in the art:

[0026] As shown in Figures 1 to 6, this invention provides a connection structure between a battery and a circuit board, including a control circuit board 5 and a battery 6, with the battery 6 electrically connected to the control circuit board 5. A positive conductive portion 51 and a negative conductive portion 52 are provided on one side of the control circuit board 5. The positive conductive portion 51 and the negative conductive portion 52 are used to connect the positive and negative terminals of the battery 3, respectively, to achieve the electrical connection between the battery 3 and the control circuit board 5. A vertically upward-extending conductive spring 53 is connected to the negative conductive portion 52. The conductive spring 53 includes a connecting end 531, a spring end 532, and a vertical rod 533 located between the connecting end 531 and the spring end 532. The spring end 532 provides elastic contact pressure, ensuring that the negative terminal of the battery 6 always maintains good contact with the negative conductive portion 52. The connecting end 531 is connected to the negative conductive part 52. The positive terminal of the battery 6 abuts against the positive conductive part 51, and the negative terminal of the battery 6 abuts against the spring end 532. The battery 6 is vertically positioned between the positive conductive part 51 and the spring end 532. By placing the positive conductive part 51 and the negative conductive part 52 at the same end, the battery 6 can be placed vertically on one side of the control circuit board 5. This design makes the space arrangement between the battery and other components more compact, reducing unnecessary gaps and significantly reducing the occupation of the internal structure. Traditional battery installation methods often require the use of multiple wires to connect the positive and negative terminals of the battery to the control circuit board, increasing assembly difficulty and the risk of failure. The same-end design achieves electrical connection directly through the conductive spring 53, eliminating the need for additional wires and simplifying the electrical connection process. Users only need to insert the battery 6 vertically to complete the installation, making it easy and intuitive to distinguish the positive and negative terminals, greatly facilitating daily use and maintenance. By setting a vertically extending conductive spring 53, the positive and negative conductive terminals of the control circuit board 5 are located at the same end, and the battery 6 is installed at the same end. When installing the battery 6, the user only needs to insert the battery 6 vertically to complete the installation. The user can intuitively and easily distinguish the positive and negative polarity of the battery 6 during installation, which greatly facilitates the user's daily use and maintenance. Especially when multiple batteries 6 need to be installed, after installing one battery 6, the other batteries 6 can be installed quickly without having to confirm the positive and negative polarity again. This same-end design makes the installation faster. As shown in Figures 1 and 2, the connecting end 531 is further connected and fixed to the control circuit board 5 by screws 54. By setting the detachable connection of screws 54, the conductive spring 53 can be effectively prevented from loosening, ensuring that the conductive spring 53 is stably and firmly fixed on the control circuit board 5, while also facilitating the disassembly, installation and replacement of the conductive spring 53.

[0027] As shown in Figures 1-3, further, the control circuit board 5 has a socket 55 and a USB interface 56 on the side of the board where the positive conductive part 51 and the negative conductive part 52 are respectively arranged. The socket 55 and the USB interface 56 provide various power supply interfaces and data transmission interfaces, which facilitates the debugging of the smart lock 200 and the charging of the battery 6.

[0028] Furthermore, as shown in Figures 1-4, on the other side of the control circuit board 5, where the positive conductive part 51 and the negative conductive part 52 are respectively arranged, there are also buttons 57 and LEDs 58. Several LEDs 58 are evenly spaced along the circumference of the control circuit board 5. The buttons 57 are used to control the control circuit board 5 by pressing, sending corresponding commands. The LEDs 58 provide indication of the working status and illumination function for the smart lock sticker 200, making it more convenient for users to operate.

[0029] Continuing as shown in Figures 1-4, further, on the other side of the control circuit board 5, where the positive conductive part 51 and the negative conductive part 52 are respectively arranged, a buzzer 59 and a factory reset button 591 are also provided. In practice, the buzzer 59 is used to provide an audible alert, reminding the user of the current operating status or abnormal situation, helping the user to understand the status of the control circuit board 5 in a timely manner and avoiding misoperation. The factory reset button 591 is used to reset the internal system settings of the control circuit board 5, allowing the user to quickly reset the internal system settings of the control circuit board 5 when needed, simplifying the maintenance process.

[0030] As shown in Figures 4 and 5, the connection structure between the battery and the circuit board in this invention further includes a mounting base 3, on which the control circuit board 5 and the battery 6 are connected. The mounting base 3 provides stable support for the control circuit board 5 and the battery 6, ensuring a stable connection between the control circuit board 5 and the mounting base 3, and guaranteeing the stability of the entire electrical system.

[0031] As shown in Figures 1-5, furthermore, the side wall of the fixing base 3 is recessed to provide battery receiving cavities 34 for accommodating batteries 6, and three batteries 6 and three battery receiving cavities 34 are provided respectively. The battery receiving cavities 34 allow the batteries 6 to be securely installed on the fixing base 3, improving the stability of the overall structural connection. Simultaneously, it helps to reasonably reduce the overall space occupied by the connection structure between the battery and the circuit board, reducing the overall size and making it easier to apply to smart lock stickers, and also contributing to the reduction of the overall size of the smart lock sticker 200. To accommodate more batteries 6 and provide more sufficient power to increase the battery life of the smart lock sticker 200, in this embodiment, three positive conductive parts 51 and three negative conductive parts 52 are provided respectively, and correspondingly, three batteries 6 and three battery receiving cavities 34 are provided respectively.

[0032] As shown in Figures 1-5, the inner wall of the battery housing 34 is further provided with a first positioning groove 341 for supporting and fixing the vertical rod 533 and a second positioning groove 342 for supporting and fixing the spring end 532. The cooperative arrangement of the first positioning groove 341 and the second positioning groove 342 ensures that the conductive spring 53 is stably installed on the fixing base 3, guaranteeing the stability of the electrical connection system. Through reasonable layout and compact design, the battery 6 and other components can be reasonably arranged, reducing unnecessary space waste. The first positioning groove 341 and the second positioning groove 342 on the inner wall of the battery housing 34 ensure that each part of the conductive spring 53 can be firmly fixed in the appropriate position, optimizing the use of internal space and ensuring the stability of the electrical connection.

[0033] This application also provides a smart lock sticker, including a battery and circuit board connection structure as described above, and a housing 2 that is circumferentially fixed to a mounting base 3 and rotates synchronously. The mounting base 3 is installed inside the housing 2. The housing 2 includes a base plate 222, which is made of a light-transmitting material to allow light from the LED beads 58 to pass through. The LED beads 58, in conjunction with the light-transmitting base plate 222, provide the smart lock sticker 200 with indication of its working status and illumination function, making it more convenient for the user to operate. A button 2221 for pressing the button 57 is provided on the outer side of the base plate 222.

[0034] As stated above, this case protects a connection structure between a battery and a circuit board, as well as a smart lock sticker. All technical solutions that are the same as or similar to this case should be considered to fall within the protection scope of this case.
