[0022] In related technologies, there are electronic door locks that can be customized, including a panel, decorative panel, and base shell. The decorative panel can be customized according to user needs, but users usually need to replace it themselves. Electronic door locks involve a variety of electronic circuits, especially the battery connection part, which is difficult for ordinary users to disassemble and install. Disassembly and replacement not only increases the technical requirements for users, but also makes the electronic interface prone to damage due to frequent plugging and unplugging, thus limiting the customization function.

[0023] Therefore, this application provides an electronic door lock 100 with a docking module 11. When the first back cover 14 is replaced, the docking module 11 is plugged into the battery 200 to achieve electrical connection. When plugged in, the docking module 11 has a mechanical connection part 111 in the depth direction that is higher than the electrical connection part 112. This allows the mechanical connection part 111 to preferentially dock with the battery 200 during assembly, which has a guiding and positioning effect, facilitates assembly, and improves the reliability of the plugging and mating.

[0024] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model.

[0025] Combination Figures 1 to 9 According to an embodiment of the present utility model, the electronic door lock 100 includes a lock body 10 and a docking module 11. The lock body 10 is provided with a mounting cavity 101 for placing a battery 200. The docking module 11 is provided on the lock body 10, and at least a part of the docking module 11 is provided in the mounting cavity 101 for plugging and cooperating with the battery 200 to realize the battery 200 to supply power to the lock body 10.

[0026] Specifically, in combination Figure 6The docking module 11 includes a mechanical connection part 111 and an electrical connection part 112. The electrical connection part 112 is used for electrical connection with the battery 200. The mechanical connection part 111 and the electrical connection part 112 extend towards the opening of the mounting cavity 101 along the depth direction of the mounting cavity 101. That is, both the mechanical connection part 111 and the electrical connection part 112 of the docking module 11 extend into the mounting cavity 101. When the battery 200 is placed in the mounting cavity 101, it can not only be placed, but also facilitate docking between the battery 200 and the docking module 11. Therefore, after the battery 200 is assembled, the mounting cavity 101 can not only place and position the battery 200, but also protect the battery 200 and support the connection structure between the battery 200 and the docking module, which helps to improve the structural stability after assembly.

[0027] The depth direction can be from the inner bottom surface of the mounting cavity 101 towards the opening of the mounting cavity 101. Generally, in order to reduce the size of the electronic door lock 100, the battery 20 is usually made into a flat shape. In this way, the thickness of the electronic door lock 100 will not increase too much after the battery 200 is installed. Therefore, the battery 200 is installed in the mounting cavity 101 along the depth direction of the mounting cavity 101, which helps to improve the structural compactness of the electronic door lock 100 and avoids the electronic door lock 100 protruding too much relative to the door body 300 after installation.

[0028] Furthermore, the height of the free end of the mechanical connection 111 relative to the inner bottom surface of the mounting cavity 101 is higher than the height of the free end of the electrical connection 112 relative to the inner bottom surface of the mounting cavity 101. That is, the height of the mechanical connection 111 is higher than the height of the electrical connection 112 relative to the inner bottom surface of the mounting cavity 101. This allows the battery 200 to dock with the docking module 11 inside the mounting cavity 101 when it is inserted into the mounting cavity 101. During docking, the battery 200 moves from the opening of the mounting cavity 101 towards the inner bottom surface of the mounting cavity 101. The mechanical connection 111 of the docking module 11 can preferentially engage with the battery 200, acting as a guide. The mechanical connection 111 guides the docking and assembly of the battery 200, making it easier for the battery 200 to engage with the electrical connection 112. This provides convenience for users in assembling the battery 200 and helps reduce damage to the electrical connectors caused by misoperation, thus protecting the electronic door lock 100.

[0029] According to the embodiment of the present utility model, the electronic door lock 100 is provided with a docking module 11 having a mechanical connection part 111. The docking module 11 is plug-in type. When the battery 200 is plugged into the docking module 11, the mechanical connection part 111 is higher than the electrical connection part 112, so that the mechanical connection part 111 can be pre-connected to the battery 200 and provide guidance and positioning effects for docking and electrical connection with the battery 200.

[0030] Furthermore, combining Figure 8In some embodiments of this utility model, the mechanical connection portion 111 includes a guide member 111a and a first positioning member 111b. The first positioning member 111b extends along the depth direction, and the guide member 111a is disposed at the free end of the mechanical connection portion 111. Specifically, the guide member 111a is disposed at the free end of the mechanical connection portion 111 and is adapted to contact the battery 200 or the connection portion of the battery 200, thereby guiding the connection portion of the battery 200 to move in the direction of the first positioning member 111b. The first positioning member 111b can guide the connection portion of the battery 200 to continue moving along the depth direction after the battery 200 is docked.

[0031] In the depth direction of the mounting cavity 101, the first positioning member 111b extends in the same direction as the electrical connection part 112. In this way, when the first positioning member 111b guides the battery 200 to move, it can directly insert and cooperate with the electrical connection part 112 when it reaches the free end of the electrical connection part 112, thereby improving the guiding effect and avoiding the problem of misalignment between the electrical connection part 112 and the battery 200, or the battery 200 being difficult to insert into the electrical connection part 112.

[0032] In some embodiments of this utility model, the guide member 111a is configured as a wedge shape with its outer contour gradually tapering in the direction away from the inner bottom surface of the mounting cavity 101. That is, in the depth direction, the end of the guide member 111a is relatively narrow, which facilitates docking with the battery 200, making it easy for the guide member 111a to extend into the electrical connection of the battery 200. Furthermore, the dimension of the guide member 111a gradually increases in the direction towards the inner bottom surface of the mounting cavity 101, which can improve the support effect after the guide member 111a is connected to the battery 200, and facilitate the stable movement of the battery 200 along the assembly direction.

[0033] In some embodiments of this invention, the guide member 111a has a chamfered edge at the free end of the mechanical connection portion 111, which facilitates the guidance of the connection portion of the battery 200 to engage with the docking module 11, thereby guiding the connection portion of the battery 200 to move along the direction of the first positioning member 111b. Furthermore, the chamfered structure is relatively rounded, making it easier for the user to find the installation position during installation. Additionally, during assembly, if other parts of the battery 200 come into contact with the guide member 111a or fail to dock successfully, the chamfer can protect the battery 200 and the mechanical connection portion 111, preventing damage.

[0034] Combination Figure 5 and Figure 6In some embodiments of this utility model, the first positioning member 111b is wedge-shaped, gradually tapering away from the inner bottom surface of the mounting cavity 101. Specifically, the first positioning member 111b is narrower in the direction away from the inner bottom surface of the mounting cavity 101 or near the free end of the mechanical connection 111, which facilitates guiding the movement of the battery 200; the first positioning member 111b gradually increases in size in the direction near the inner bottom surface of the mounting cavity 101, which provides support as the mating depth between the first positioning member 111b and the battery 200 gradually increases, thereby improving the stability of the mechanical connection 111 guiding the connection of the battery 200, improving the stability of the battery 200 when it is plugged into the electrical connector, and improving the overall structural stability after connection.

[0035] Alternatively, the first positioning member 111b can gradually shrink along the depth direction of the mounting cavity 101 toward the opening direction of the mounting cavity 101, making it easy to cooperate with the battery 200 during assembly. The stability gradually improves during the assembly process, which is conducive to guiding the battery 200 to be inserted into the electrical connection part 112 and also helps to improve the support effect after assembly.

[0036] In addition, the wedge-shaped structure helps to disperse pressure during guidance, reduce stress concentration, and facilitate the movement of the battery 200. Especially in the event of shaking during installation, the mechanical connection part 111 can still contact the battery 200, providing protection and improving structural stability.

[0037] According to a specific embodiment of the present invention, the electronic door lock 100 has a first positioning member 111b in the shape of an elongated strip. The first positioning member 111b includes a first positioning surface and a second positioning surface arranged opposite to each other, as well as a third positioning surface and a fourth positioning surface arranged opposite to each other. The first positioning surface and the second positioning surface both cooperate with the electrical contact point 211 of the battery 200. A first inclined surface extending outward is provided between the first positioning surface and the third and fourth positioning surfaces, and the width of the first inclined surface gradually increases from the first end to the second end. A second inclined surface extending outward is provided between the second positioning surface and the third and fourth positioning surfaces, and the width of the second inclined surface gradually decreases from the first end to the second end.

[0038] Combination Figure 4In some embodiments of this utility model, the mounting cavity 101 has a first end and a second end opposite to each other in the length direction, the docking module 11 is disposed at the first end, and the first positioning member 111b is configured as a strip that gradually tapers from the first end to the second end. Specifically, the space between the first end and the second end is a accommodating space for accommodating the battery 200. The direction from the first end to the second end is the direction in which the first positioning member 111b gradually approaches the accommodating space in the middle of the mounting cavity 101. On the side facing the middle accommodating space, the size of the first positioning member 111b is smaller or narrower, so that the battery 200 can not only be inserted and matched with the docking module 11 from the depth direction, but also be guided from the direction perpendicular to the depth of the mounting groove, such as the length direction of the mounting cavity 101. In this way, after the battery 200 enters the accommodating space, it can contact the first positioning member 111b, and the first positioning member 111b can easily achieve a certain guiding effect along the length direction of the mounting cavity 101. Thus, the first positioning member 111b or the mechanical connection part 111 plays a guiding role in multiple directions, which is conducive to improving the matching effect between the docking module 11 and the battery 200, and is conducive to protecting the electrical connection part 112 and the connection part of the battery 200.

[0039] In some embodiments of this utility model, multiple electrical connection portions 112 are provided, and mechanical connection portions 111 are provided between adjacent electrical connection portions 112. Specifically, the multiple electrical connection portions 112 can be connected to multiple terminals of the battery 200 respectively. The mechanical connection portions 111 are provided between adjacent electrical connection portions 112, thereby forming a support between the multiple electrical connection portions 112, protecting the surrounding electrical connection portions 112, and preventing damage to the electrical connection portions 112 due to uneven force applied by the user during insertion.

[0040] Optionally, a mark may be provided on the mechanical connection part 111. Since the mechanical connection part 111 protrudes from the multiple electrical connection parts 112, the mark on the mechanical connection part 111 is easily visible to the user, thereby making it easier for the user to determine the direction of insertion.

[0041] Alternatively, the mechanical connection portion 111 can separate multiple electrical connection portions 112, with the number of electrical connection portions 112 on both sides of the mechanical connection portion 111 being different, thereby making it easier for the user to determine the mating direction.

[0042] Furthermore, multiple mechanical connection parts 111 can be provided. When there are many electrical connection parts 112, multiple mechanical connection parts 111 can be spaced between multiple electrical connection parts 112 to improve the reliability of insertion and facilitate the user to determine the mating direction during insertion based on the arrangement of multiple mechanical connection parts 111.

[0043] Specifically, mechanical connection portions 111 are spaced apart between electrical connection portions 112 so that each electrical connection portion 112 sequentially mates with the battery 200 connection portion.

[0044] In one specific embodiment of this utility model, there are five electrical connection parts 112, which are respectively the charging input terminal, GND terminal, charging state 1 terminal, charging state 2 terminal, and VCC terminal. When the mechanical connection part 111 is not provided, attention should be paid to the insertion direction during connection. Reverse connection will lead to incorrect connection of different ports, resulting in functional failure or even short circuit and burnout. When the mechanical connection part 111 is provided and it is spaced between the battery 200 connection parts, the order can be as follows: charging input terminal, mechanical connection part 111, GND terminal, charging state 1 terminal, charging state 2 terminal, and VCC terminal, thus avoiding the problem of reverse insertion.

[0045] In some embodiments of this utility model, the mechanical connection part 111 is constructed in the shape of an elongated strip, which facilitates the insertion effect and has strong structural stability. The elongated shape also makes it easier for users to determine the insertion direction.

[0046] The electrical connection portion 112 can also be constructed as an elongated strip to facilitate insertion. The depth extension length of the mechanical connection portion 111 is greater than that of the electrical connection portion 112. Thus, when the battery 200 is inserted into the docking module 11, it can first be inserted into the mechanical connection portion 111. The mechanical connection portion 111 guides the battery 200 into the mounting cavity 101. During installation, the battery 200 can directly connect to the electrical connection portion 112 without requiring the user to verify the correctness of the connection. Furthermore, due to the longer extension length of the mechanical connection portion 111, the user can easily determine the insertion position. Additionally, there may be only one mechanical connection portion 111, or several may be spaced apart among multiple electrical connection portions 112, resulting in a smaller number that facilitates insertion into the mechanical connection portion 111.

[0047] Combination Figure 4 and Figure 8 The mechanical connection 111 has a larger dimension along the width of the mounting cavity 101 than the electrical connection 112, which improves the structural stability of the mechanical connection 111. When the mechanical connection 111 is inserted into the battery 200, it provides support at the connection position, thereby protecting the electrical connection 112 and preventing it from bending or being damaged by shaking during assembly.

[0048] Furthermore, in related technologies, the electrical connection and the welding positioning part are usually injection molded as a single unit. When welding the electrical connection to the substrate, soldering is usually used. The temperature of the molten solder paste is usually between 250 and 350 degrees Celsius. At this temperature, the molding position of the electrical connection and the welding positioning part may become loose. Therefore, if the electrical connection is used for positioning during welding, the positioning will be unreliable. Therefore, in this application, a positioning part 114 is provided on the docking module 11 and embedded into the substrate to achieve a pre-positioning effect, making the positioning more reliable during welding and the welding position of the electrical connection 112 more accurate. As a result, the electrical connection 112 can be accurately aligned with the battery 200 connection part when docking.

[0049] Specifically, in some embodiments of this utility model, the docking module 11 includes a base 113 and at least one positioning part 114. The positioning part 114 is embedded in the periphery of the base 113. An electrical connection part 112 and a mechanical connection part 111 are disposed on the base 113. The electrical connection part 112 includes a first connector 112a and a second connector 112b. The first connector 112a and the second connector 112b are respectively connected to opposite sides of the base 113. The first connector 112a is electrically connected to the battery 200, and the second connector 112b is connected to the lock body 10. Specifically, the positioning part 114 can be embedded into the base 113 by welding. The positioning part 114 can be connected to a circuit board to achieve pre-positioning, thereby facilitating the welding of the electrical connection part 112 onto the base 113.

[0050] Specifically, multiple mounting holes can be provided on one side of the base 113, and the first connector 112a can be welded to the other side of the base 113. During actual assembly, the second connector 112b is inserted into the mounting hole, which helps to improve the positioning accuracy. The second connector 112b is connected to the circuit board. Since the first connector 112a and the second connector 112b are linked through the base 113, the electrical connection part 112 can cooperate with the battery 200 to achieve electrical connection.

[0051] Alternatively, the second connector 112b can also be welded to the base 113.

[0052] Furthermore, combining Figure 2 and Figure 5 In some embodiments of this utility model, the lock body 10 includes a bottom shell 12, a mounting member 13 and a first back shell 14. The mounting member 13 is connected to the lock body 10, and the mounting cavity 101 is provided in the mounting member 13. The first back shell 14 is detachably connected between the lock body 10 and the mounting member 13, and a portion of the first back shell 14 extends out of the mounting member 13.

[0053] In other words, the first back cover 14 serves a decorative purpose. Furthermore, users can pull the electronic door lock 100 by holding the edge of the first back cover 14 to open or close the door. Users can customize the first back cover 14 according to their needs, such as by replacing it with a different design, thus fulfilling their personalized customization requirements for the electronic door lock 100.

[0054] When users replace different first back covers 14, the thickness of the different first back covers 14 may vary due to their individual differences. Therefore, when the thickness of the first back cover 14 is greater, the distance between the battery 200 and the docking module 11 increases, potentially leading to a decrease in the reliability of the contact between the second electrical connection portion 112 of the battery 200 and the electrical connection portion 112 of the docking module 11. Therefore, to accommodate more first back covers 14 of varying thicknesses, the extension distance of the electrical connection portion 112 in the docking module 11 along the depth direction or assembly direction can be larger, ensuring that the electrical connection between the battery 200 and the docking module 11 is not affected by the thickness or size of the first back cover 14, thus guaranteeing reliable contact.

[0055] Furthermore, when the electrical connection part 112 is too long, it is prone to deformation during actual insertion, leading to misalignment and circuit damage, or even damage to the electronic door lock 100 due to insertion errors. Therefore, by providing a mechanical connection part 111 on the docking module 11, the mechanical connection part 111 protrudes from the electrical connection part 112 in the assembly direction. During actual assembly, the protruding mechanical connection part 111 can preferentially dock with the battery 200, and during docking, it can serve as a guide and positioning function. Then, the electrical connection part 112 contacts the battery 200 for electrical connection. In this way, the safety and reliability of the electrical connection can be guaranteed even with frequent replacement of the first back cover 14.

[0056] Specifically, the mounting component 13 and the first back cover 14 can be connected by screws or snap-fit ​​connections, etc., and this utility model is not limited to this.

[0057] It is understood that the bottom shell 12 is usually fixed on the door body 300, the docking module 11 is fixedly connected to the bottom shell 12, the adaptive docking module 11 is electrically connected to the lock body 10, and after the battery 200 is installed on the mounting part 13, power can be supplied through the docking module 11. In this way, when the user replaces the battery 200, there is no need to connect wires, but only to place the battery 200 directly in place. On the other hand, the first back shell 14 can be pre-installed on the mounting part 13 and then assembled on the bottom shell 12, which also facilitates the operation and replacement of the first back shell 14.

[0058] Combination Figure 2 and Figure 3In some embodiments of this utility model, the lock body 10 further includes a second back cover 16. The second back cover 16 is provided with a first magnetic element, and the mounting member 13 is provided with a second magnetic element 132. The first magnetic element and the second magnetic element 132 can be magnetically engaged and disengaged to allow the second back cover 16 to be detachably attached to the mounting member 13. This facilitates the user's disassembly and assembly of the second back cover 16, and the magnetic engagement improves the user experience. Furthermore, the second back cover 16 can also be replaceable to enhance the personalization of the electronic door lock 100.

[0059] Furthermore, the second back cover 16 may also include an inner plate 15, which is stacked inside the second back cover 16 to improve the structural strength of the second back cover 16. Specifically, the inner plate 15 can be adhered to the inside of the second back cover 16. Even further, a hollow structure can be constructed on the inner plate 15, forming multiple positioning areas. For example, the first magnetic element can be installed in the first positioning area 151. Simultaneously, the inner plate 15 can also serve as a concealing component, hiding the internal structure of the electronic door lock 100. For example, the second back cover 16 can cover the mounting component 13 and the battery 200, improving the aesthetics of the electronic door lock 100.

[0060] Specifically, after the mounting component 13 is fixed to the first back cover 14, the mounting component 13 is fixed to the bottom cover 12 by tightening the fixing screws from the front. Then, the battery 20 is placed into the mounting cavity 101 of the mounting component 13, thus fixing the battery 200. By setting the second back cover 16, the battery 200 can be protected while ensuring the consistency of the appearance of the electronic door lock 100.

[0061] Furthermore, when wireless charging is required, the second back cover 16 can also be equipped with a magnetic element that attracts external power supply devices (such as power banks or wireless charging pads) to the electronic door lock 100 or the outer surface of the second back cover 16. This allows the external power supply device to be attracted to the second back cover 16 for charging, facilitating user charging of the battery 200. The inner plate 15 can be provided with a second positioning area for positioning the magnetic element to facilitate assembly.

[0062] For example, the magnetic element can be an iron sheet or a magnet made of ferromagnetic material, and the external power supply device is equipped with a corresponding magnet.

[0063] Combination Figure 1 and Figure 3In some embodiments of this utility model, the electronic door lock 100 includes a first part 10a and a second part 10b arranged on both sides of the door. A battery 200 is disposed in the first part 10a. Both the first part 10a and the second part 10b include a first back cover 14 and a second back cover 16. Specifically, the first part 10a of the electronic door lock 100 is installed inside the door body 300. The battery 200 being disposed in the first part 10a allows the user to easily charge the battery 200 at home, such as by replacing the battery 200, connecting it to a power source for charging, or using a wireless charging device. Figure 1 The first part 10a may also be provided with an operating element for locking the door, so as to achieve multiple locking of the door 300. The second part 10b of the electronic door lock 100 may be provided on the outside of the door 300, in conjunction with Figure 3 Part 2, 10b, can be configured with a control area for opening the door, such as displaying a numeric keypad for entering a password, a control area for recognizing fingerprints, or a keyhole for inserting a key to unlock.

[0064] Combination Figure 5 and Figure 9 According to the present invention, the battery 200 is used in the aforementioned electronic door lock 100. The battery 200 has a first mating groove 201 and a second mating groove 202. The mechanical connecting part 111 is inserted into the second mating groove 202 to realize the pre-positioning of the docking module 11 and the battery 200. An electrical contact point 211 is provided in the first mating groove 201. The electrical connecting part 112 is inserted into the first mating groove 201 and contacts the electrical contact point 211 to realize the electrical connection between the docking module 11 and the battery 200.

[0065] Specifically, in combination Figure 9 The battery 200 includes a plurality of second positioning members 210, which are arranged at intervals. A portion of the plurality of second positioning members 210 can form a first mating groove 201, and a portion can form a second mating groove 202. An electrical contact point 211 is provided in the first mating groove 201.

[0066] More specifically, when the first positioning member 111b of the mechanical connection 111 and the second positioning member 210 of the battery 200 mate with the mechanical connection 111 and the battery 200 or the connection of the battery 200, the mechanical connection 111 guides and restricts the connection between the mechanical connection 111 and the battery 200 or the connection of the battery 200.

[0067] It is understood that the mechanical connection part 111 is configured as a pin-shaped elongated structure. The end of the mechanical connection part 111 is provided with a guide member 111a for guiding the chamfer, which facilitates guiding the mechanical connection part 111 to mate with the second mating groove 202 of the battery 200. The elongated mechanical connection part 111 has side surfaces on both sides, namely the first positioning member 111b. The side surfaces of the mechanical connection part 111 mate with the second mating groove 202 of the battery 200 and the corresponding side surfaces of the battery 200, that is, the first positioning member 111b and the second positioning member 210 cooperate with each other, which can position and guide the insertion direction and angle of the electrical connection part 112, and better ensure the reliability of the insertion.

[0068] The battery 200 has electrical contact points, which are elongated. The electrical connection part 112 extends into the battery 200 and is always in contact with the electrical contact points.

[0069] It is understood that the electrical connection part 112 is a pin, and the battery 200 has protruding contacts. When the pin is inserted into the battery 200, it contacts the contacts, and the contacts undergo partial elastic deformation, which makes the contact more stable and the signal connection reliable. Furthermore, this structure is applied to a customized electronic door lock 100. Since the distance that the electrical connection part 112 extends into the battery 200 will change due to the thickness of the customized first back cover 14 replaced by the user, the electrical contact is set to be elongated. This ensures that the electrical connection part 112 can always maintain a reliable electrical contact connection within a certain stroke.

[0070] Furthermore, the battery 200 also includes a coil 220, which is disposed on the side of the battery 200 near the second back cover 16.

[0071] To meet the current demand for wireless charging, electronic door locks 100 are typically equipped with wireless charging functionality. This wireless charging function usually requires a coil 220 to generate current through electromagnetic induction to charge the battery 200. Due to the limited strength of the magnetic field, the coil 220 usually needs to be closer to the charging device. The conventional design is to directly attach the coil 220 to the inside of the second back cover 16 to achieve better conversion. However, when the user disassembles the customized first back cover 14, the exposed coil 220 requires frequent disassembly and reassembly, increasing the difficulty of replacement. Furthermore, as an electronic component, the coil 220 is easily damaged, which is not conducive to protection. By integrating the coil 220 into the battery 200 and placing the coil 220 on the side of the battery 200 closer to the second back cover 16, the integrated design with the battery 200 makes it easier for users to replace the battery and ensures the reliability of the internal electronic circuitry.

[0072] It should be noted that in practical applications, the depth direction can be the front-back direction, the width direction can be the left-right direction, and the height direction can be the up-down direction.
