[0033] Reference Figures 1 to 5 This embodiment of the battery-powered door lock includes a base 100, a circuit board 200, a power supply module 300, a conductive spring 400, and a power supply cover plate 500. The base 100 has a power supply mounting hole 101 and an electronic control mounting cavity 102; the circuit board 200 is disposed in the electronic control mounting cavity 102; the power supply module 300 is inserted into the power supply mounting hole 101 along its depth direction, and a conductive part is disposed on the outer side of the power supply module 300; the conductive spring 400 is disposed on the base 100 and located at the bottom of the power supply mounting hole 101, one end of the conductive spring 400 is connected to and conducts through the circuit board 200, and the other end of the conductive spring 400 abuts against the conductive part of the power supply module 300, and the conductive spring 400 can apply a force to disengage the power supply module 300 from the power supply mounting hole 101; the power supply cover plate 500 is detachably disposed on the base 100 and can cover or open the opening of the power supply mounting hole 101.
[0034] One end of the conductive spring 400 abuts against the conductive part of the power supply module 300, and the other end of the conductive spring 400 is directly connected to and conducts electricity to the circuit board 200. The power supply module 300 can directly supply power to the circuit board 200 through the conductive spring 400. By arranging the positions of the power supply mounting hole 101 and the electronic control mounting cavity 102, there is no need to use wires for power supply, which makes the structure of the door lock simpler, reduces production costs, and makes production more stable.
[0035] In this embodiment, the base 100 is provided with a partition plate 1211, which is located between the bottom of the power supply mounting hole 101 and the electrical control mounting cavity 102. The conductive spring 400 includes an elastic spiral portion 410, a mounting portion 420, and a pin portion 430. The elastic spiral portion 410 is connected to the side of the mounting portion 420 near the power supply mounting hole 101 and abuts against the conductive portion. The pin portion 430 is connected to the side of the mounting portion 420 near the circuit board 200 and is fixedly connected to and conductive to the circuit board 200. The partition plate 1211 is provided with a spring mounting groove 1212, and the mounting portion 420 is embedded in the spring mounting groove 1212.
[0036] The conductive spring 400 is inserted and fixed to the spring mounting groove 1212 of the partition plate 1211 through the mounting part 420. The elastic spiral part 410 abuts against the power supply module 300 to make close contact with the conductive part of the power supply module 300 and to apply a force to the power supply module 300 to disengage from the power supply mounting hole 101. The conductive spring 400 is fixedly connected to the circuit board 200 through the pin part 430. The conductive spring 400 is fixed to the partition plate 1211 through the mounting part 420 so that the elastic force of the elastic spiral part 410 is not transmitted to the pin part 430, so that the connection between the conductive spring 400 and the circuit board 200 can be more stable, reducing the risk of the conductive spring 400 and the circuit board 200 being disconnected. The conductive spring 400 can be installed on the base 100 relatively easily and firmly, and the installation method is relatively simple and easy to implement.
[0037] Specifically, the mounting portion 420 is annular and is embedded in the spring mounting groove 1212. It is understood that in some other embodiments, the mounting portion 420 may also be a plate structure embedded in the spring mounting groove 1212.
[0038] In this embodiment, the pin portion 430 is soldered to the circuit board 200, providing a relatively secure connection and good conductivity. It is conceivable that in other embodiments, the pin portion 430 may also be fixed to the circuit board 200 by riveting or bonding; those skilled in the art can choose the appropriate method based on actual needs.
[0039] In this embodiment, the base 100 includes a bottom shell 121 and a cover plate 122. The bottom shell 121 and the cover plate 122 form a power supply mounting hole 101 and an electrical control mounting cavity 102. A partition plate 1211 is located on the bottom shell 121, and a spring mounting groove 1212 is located on the side of the bottom shell 121 near the cover plate 122. The cover plate 122 covers the opening of the spring mounting groove 1212. During assembly, the mounting part 420 of the conductive spring 400 is inserted into the spring mounting groove 1212 of the bottom shell 121, and the circuit board 200 is installed on the bottom shell 121. Then, the cover plate 122 is assembled with the bottom shell 121 to form the power supply mounting hole 101 and the electrical control mounting cavity 102. At this time, the cover plate 122 covers the opening of the spring mounting groove 1212 to prevent the conductive spring 400 from loosening, and the installation of the conductive spring 400 is relatively secure.
[0040] In this embodiment, the power supply module 300 is a battery box with four battery receiving holes 310. The power supply module 300 uses a battery box with multiple battery receiving holes 310, each of which can accommodate dry cell batteries. The power supply module 300 has a relatively simple structure and good versatility.
[0041] Specifically, the battery box has four battery receiving holes 310. It is conceivable that the battery box could also have two, three, or more battery receiving holes 310, which can be selected by those skilled in the art according to actual needs.
[0042] It is understood that in other embodiments, the power supply module 300 may also be, for example, a block-shaped battery, and this is not limited here.
[0043] In this embodiment, two conductive springs 400 are provided, arranged side by side. The power supply module 300 has two conductive parts, and the two conductive springs 400 abut against the two conductive parts in a one-to-one correspondence. The two conductive springs 400 correspond to the positive and negative terminals of the power supply module 300 respectively, and can increase the pushing force on the power supply module 300, ensuring that the power supply module 300 can be stably pushed and moved by the conductive springs 400 when the power supply cover 500 is removed, facilitating the removal of the power supply module 300.
[0044] In this embodiment, a threaded fastener 600 is also included. One end of the power supply cover plate 500 is provided with a snap-fit portion 510, and the other end of the power supply cover plate 500 is provided with a mounting through hole 520. The base 100 is provided with a snap-fit mating portion 103 and a threaded hole 104. The snap-fit portion 510 of the power supply cover plate 500 is snapped into the snap-fit mating portion 103 of the base 100. The threaded fastener 600 passes through the mounting through hole 520 and is threadedly connected to the threaded hole 104, thereby locking the power supply cover plate 500 to the base 100. One end of the power supply cover 500 is engaged with the base 100's engagement part 103 via the snap-fit part 510, and the other end is threaded to the base 100's threaded hole 104 via a threaded fastener 600, thus completing the installation of the power supply cover 500 on the base 100. Only one threaded fastener 600 is needed to complete the installation and fixation of the power supply cover 500, which saves on the number of parts compared to the previous method of using two threaded fasteners 600, and makes disassembly and assembly more convenient.
[0045] Specifically, threaded fastener 600 is a screw.
[0046] In this embodiment, the snap-fit part 510 is a snap-fit block, and the snap-fit mating part 103 is a snap-fit groove. The snap-fit block snaps into the snap-fit groove, so that one end of the power supply cover 500 is snapped into the base 100. The structure is simple and easy to implement.
[0047] It is understood that in other embodiments, the snap-fit part 510 can be a slot and the snap-fit mating part 103 can be a snap-fit block, which can also achieve the snap-fit mating of the two.
[0048] In this embodiment, the base 100 includes a mounting strip 110, a power supply base 120, and a door lock body 130. Both the power supply base 120 and the door lock body 130 are mounted on one side of the mounting strip 110. A power supply mounting hole 101 and an electronic control mounting cavity 102 are located in the power supply base 120. The power supply base 120 and the door lock body 130 are arranged along the length of the mounting strip 110. This allows the mounting strip 110, the power supply base 120, and the door lock body 130 to be manufactured separately and then assembled to form the base 100. When a part of the structure is damaged, it can be selectively disassembled and replaced, facilitating maintenance.
[0049] In this embodiment, the power supply mounting hole 101 has a rectangular cross-section, and the length direction of the cross-section of the power supply mounting hole 101 is parallel to the length direction of the mounting strip 110, which makes the power supply mounting hole 101 relatively flat, which helps to reduce the thickness of the door lock and make the structure more compact.
[0050] Specifically, the battery box is also rectangular.
[0051] In the description of this specification, the references to terms such as "one embodiment," "some embodiments," "illustrative embodiment," "example," "specific example," or "some examples," etc., indicate that a specific feature, structure, material, or characteristic described in connection with that embodiment or example is included in at least one embodiment or example of the present invention.
