[0035] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0036] Please see Figures 1 to 4 This utility model provides a battery structure that can be used in a smart door. The smart door includes a door body and an electrical structure. The battery structure can be installed in the door body and electrically connected to the electrical structure to supply power to the electrical structure.

[0037] Examples of electrical structures include, but are not limited to, door lock structures and doorbell structures.

[0038] The battery structure includes a housing 10, a battery pack 20, and a circuit board 30. The housing 10 has a receiving groove 101 for connection to the door. The battery pack 20 is detachably installed in the receiving groove 101 and is a rechargeable battery pack. The circuit board 30 is located in the receiving groove 101 and electrically connected to the battery pack 20, and is used for electrical connection to the power-consuming structure.

[0039] Understandably, the battery pack 20 and circuit board 30 are housed in the outer casing 10, which is located on the door. The outer casing 10 protects the battery pack 20 and circuit board 30 and facilitates their installation on the door. The battery pack 20 can be installed in the receiving slot 101 and electrically connected to the circuit board 30. The circuit board 30 is electrically connected to the power-consuming structure, enabling the battery structure to supply power to the power-consuming structure. The battery pack 20 is a rechargeable battery pack. When the stored power in the battery pack 20 is insufficient, the battery 21 can be removed from the receiving slot 101, charged, and then reinstalled in the receiving slot 101 and electrically connected to the circuit board 30, allowing the battery pack 20 to supply power to the power-consuming structure again. The battery structure of this embodiment can supply power to the power-consuming structure, making the smart door suitable for situations where there is no pre-existing electrical potential in the house and it is inconvenient to modify the wiring, thus improving the adaptability of the smart door.

[0040] It is worth noting that in this embodiment of the invention, the battery structure and the power supply structure are separately configured, which facilitates the assembly and disassembly of the battery pack 20. Specifically, the circuit board 30 can be electrically connected to the power connector, and the power connector extends to and is electrically connected to the power supply structure. For example, as shown... Figure 2As shown, the housing 10 is provided with an electrical connection hole 102. The circuit board 30 is electrically connected to one end of the connecting wire, and the other end of the connecting wire passes through the electrical connection hole 102 and extends to the power-consuming structure, so as to realize the electrical connection between the circuit board 30 and the power-consuming structure, so that the battery structure can supply power to the power-consuming structure.

[0041] For example, battery pack 20 includes one or more batteries 21.

[0042] In some embodiments, the battery 21 of the battery pack 20 is slidably disposed in the receiving groove 101 so that the battery 21 can slide to be detachably electrically connected to the circuit board 30. It is understood that after the battery 21 is disposed in the receiving groove 101, the battery 21 can slide relative to the housing 10 to be detachably electrically connected to the circuit board 30. When the stored charge in the battery 21 is insufficient, the battery 21 can also slide relative to the housing 10 to separate from the circuit board 30, allowing the battery 21 to be removed from the receiving groove 101 and then charged. This facilitates the installation and removal of the battery 21 and the electrical connection between the battery 21 and the circuit board 30.

[0043] For example, such as Figure 2 and Figure 4 As shown, the battery 21 can be electrically connected to the circuit board 30 by plugging it in. For example, the battery 21 has a first plug-in portion 211 and the circuit board 30 has a second plug-in portion 31. When the battery 21 is placed in the receiving groove 101, the first plug-in portion 211 of the battery 21 faces the second plug-in portion 31 of the circuit board 30, and the battery 21 is pushed to slide towards the circuit board 30, so that the first plug-in portion 211 and the second plug-in portion 31 are plugged in to realize the electrical connection between the battery 21 and the circuit board 30.

[0044] For example, the battery 21 can be electrically connected to the circuit board 30 by means of contact conduction.

[0045] Of course, in other embodiments, the battery 21 may also be electrically connected to the circuit board 30 via a flexible connector.

[0046] In some embodiments, the housing 10 includes a shell 11, which includes at least a base plate 111 and a first side plate 112. The base plate 111 has the first side plate 112 on at least one side along a first direction, and the base plate 111 and the first side plate 112 together form a receiving groove 101. The base plate 111 extends along a second direction, and the battery 21 is slidably connected to the base plate 111 and the first side plate 112. The battery 21 is slidable relative to the base plate 111 and the first side plate 112 along the second direction, so that the battery 21 can be electrically connected to the circuit board 30. The second direction is perpendicular to the first direction. It is understood that the battery 21 is slidable relative to the base plate 111 and the first side plate 112, and the two first side plates 112 and the base plate 111 together can define the sliding direction of the battery 21, so that the battery 21 can slide stably along the second direction to be electrically connected to the circuit board 30, or so that the battery 21 can slide to be separated from the circuit board 30.

[0047] For example, the first direction can be as follows Figure 1 As shown in the Z direction, the second direction can be as follows: Figure 1 As shown in the X direction. The base plate 111 extends in the X direction, and the circuit board 30 is located on one side of the battery 21 in the X direction. The battery 21 can abut against the base plate 111 and slide relative to the base plate 111 and the two first side plates 112 in the X direction, so that the battery 21 is electrically connected to the circuit board 30.

[0048] like Figure 3 As shown, in some embodiments, the base plate 111 has first side plates 112 on opposite sides along the first direction, and the battery 21 is snapped between the two first side plates 112. This further defines the sliding direction of the battery 21, allowing the battery 21 to slide more stably along the second direction.

[0049] In some embodiments, the adjacent sides of the battery 21 abut against the base plate 111 and the first side plate 112 respectively and are able to slide relative to the base plate 111 and the first side plate 112.

[0050] In some embodiments, at least one first side plate 112 has a plurality of first protrusions 1121 protruding toward the battery 21, and the plurality of first protrusions 1121 are arranged sequentially along a second direction. This facilitates the plurality of first protrusions 1121 abutting against the battery 21, guiding the battery 21 to slide along the second direction to make electrical connection with the circuit board 30, while reducing the frictional force when the battery 21 slides relative to the first side plate 112, and leaving an air gap between the battery 21 and the first side plate 112, which facilitates user control of the sliding of the battery 21.

[0051] In some embodiments, the housing 11 further includes two second side plates 113, which are spaced apart on opposite sides of the base plate 111 along a second direction. The second side plates 113 connect to the two first side plates 112, and at least the base plate 111, the two first side plates 112, and the two second side plates 113 enclose a receiving groove 101. It is understood that the battery 21 and the circuit board 30 are located between the two second side plates 113. The second side plates 113 can further limit the sliding range of the battery 21, preventing the battery 21 from falling off the housing 10 and being damaged, thus further protecting the battery 21.

[0052] For example, such as Figure 2 As shown, the sides of the two first side plates 112 and the two second side plates 113 away from the bottom plate 111 enclose the opening 1011 of the receiving groove 101. After the battery 21 is charged, it can slide into the receiving groove 101 through the opening 1011. After the battery 21 abuts against the bottom plate 111, the battery 21 can slide relative to the bottom plate 111 and the two first side plates 112 in the X direction to approach the circuit board 30, so that the battery 21 can be electrically connected to the circuit board 30.

[0053] like Figure 4 As shown, the second side plate 113 further protrudes towards the battery 21 with a second protrusion 1131. In this way, when the battery 21 slides along the second direction to separate from the circuit board 30, the circuit can abut against the second protrusion 1131, so that there is a gap between the battery 21 and the second side plate 113, making it convenient to remove the battery 21 from the receiving groove 101.

[0054] For example, the second protrusion 1131 may be one or more. Figure 4 As shown, the second side plate 113 has two second protrusions 1131 protruding towards the battery 21, and the two second protrusions 1131 are spaced apart in the Z direction.

[0055] like Figures 3 to 5 As shown, in some embodiments, the battery pack 20 includes at least two batteries 21, which are located on opposite sides of the circuit board 30 along the second direction. It is understood that including at least two batteries 21 in the battery pack 20 is beneficial for improving the energy density of the battery pack 20 and meeting the power supply requirements for extended periods. Furthermore, the location of the two batteries 21 on opposite sides of the circuit board 30 along the second direction facilitates the structural design of the housing 11, allowing the two batteries 21 to slide independently into the receiving groove 101 to achieve electrical connection with the circuit board 30. Additionally, it helps control the thickness of the battery structure, making the thickness of the battery structure compatible with the thickness of the door, thus facilitating the installation and use of the battery structure.

[0056] Specifically, the circuit board 30 may be fastened to the housing 11, and / or the circuit board 30 may be glued to the housing 11 so that the circuit board 30 is stably disposed in the receiving groove 101.

[0057] like Figure 3 and Figure 4 As shown, in some embodiments, a threaded post 1122 protrudes from one side of a first side plate 112 facing the receiving groove 101, and a clearance hole 112a is provided on the other first side plate 112 corresponding to the threaded post 1122. After the circuit board 30 is received in the receiving groove 101, fasteners such as screws and bolts can pass through the clearance hole 112a and the mounting hole of the circuit board 30 and be threadedly connected to the threaded post 1122 to fasten the circuit board 30 to the housing 11.

[0058] Furthermore, the circuit board 30 is provided with second plug-in portions 31 on opposite sides along the second direction, and the two second plug-in portions 31 are respectively plugged into and connected to the first plug-in portions 211 of the two batteries 21.

[0059] like Figure 5 As shown, in some embodiments, the first side plate 112 with threaded post 1122 is also provided with a positioning member 1123. The positioning member 1123 is used to engage with the positioning hole of the circuit board 30 to realize the positioning of the circuit board 30, so that the fastener can pass through the mounting hole of the circuit board 30 and be threadedly connected to the threaded post 1122.

[0060] In some embodiments, the battery structure further includes a limiting member 40. When the battery 21 slides to connect with the circuit board 30, the limiting member 40 is connected to the housing 10 or the circuit board 30, and to the battery 21. The limiting member is used to limit the battery 21, ensuring a stable electrical connection between the battery 21 and the circuit board 30. When the battery 21 has insufficient stored power, the limiting member 40 can be separated from the housing 10 or the circuit board 30, and / or separated from the battery 21, to control the battery 21 to slide away from the circuit board 30 and remove the battery 21 from the receiving slot 101 for charging.

[0061] In one example, the limiting member 40 is provided with a slot. When the battery 21 slides to be electrically connected to the circuit board 30, the battery 21 and the circuit board 30 are engaged in the slot of the limiting member 30. The limiting member 40 can restrict the sliding of the battery 21 relative to the circuit board 30, so that the battery 21 and the circuit board 30 can maintain a stable electrical connection.

[0062] In another exemplary embodiment, the battery 21 is placed in the receiving slot 101 and located between a second side plate 113 and a circuit board 30. After the circuit board 21 slides along the second direction to be electrically connected to the circuit board 30, the limiting member 40 can be inserted between the battery 21 and the second side plate 113. The opposite sides of the limiting member 40 are stably abutted against the second side plate 113 and the battery 21, restricting the battery 21 from sliding relative to the circuit board 30, so that the battery 21 and the circuit board 30 can maintain a stable electrical connection.

[0063] Understandably, the limiting method of the limiting component 40 includes, but is not limited to, the two methods mentioned above. The specific method can be adjusted according to the actual situation and is not limited here.

[0064] Furthermore, the limiting member 40 abuts against the side of the battery 21 opposite to the circuit board 30. In this way, the limiting member 40 can provide a force in the sliding direction of the battery 21, so that the battery 21 can be stably abutted against the circuit board under the limiting action of the limiting member 40.

[0065] Specifically, the outer casing 10 includes a housing 11, which has a receiving groove 101. The limiting member 40 includes a first limiting portion 41 and a second limiting portion 42, with the second limiting portion 42 bent relative to the first limiting portion 41. The opposite sides of the first limiting portion 41 abut against the housing 11 and the side of the battery 21 facing away from the circuit board 30, respectively. The second limiting portion 42 is located on the side of the battery 21 facing the opening 1011 of the receiving groove 101. Understandably, when the battery 21 slides to be electrically connected to the circuit board 30, the first limiting part 41 fills the gap between the side of the battery 21 away from the circuit board 30 and the housing 10, so that the opposite sides of the first limiting part 41 abut against the housing 11 and the battery 21 respectively, thereby limiting the battery 21. The second limiting part 42 of the limiting member 40 is located on the side of the battery 21 facing the opening 1011, so that when the battery 21 is low on power, the user can control the second limiting part 42 from the opening 1011 to remove the limiting member 40 from the receiving groove 101.

[0066] For example, such as Figure 3 As shown, the two first side plates 112 and the two second side plates 113, on the side away from the bottom plate 111, enclose the opening 1011 of the receiving groove 101. The two opposite sides of the first limiting part 41 along the X direction respectively abut against the second side plate 113 and the battery 21. The second limiting part 42 is connected to one side of the first limiting part 41 along the Y direction and bends relative to the first limiting part 41, so that the second limiting part 42 is located on the side of the battery 21 along the Y direction facing the opening 1011, which makes it convenient for the user to control the second limiting part 42 from the opening 1011 to remove the limiting member 40.

[0067] It is understandable that the second limiting part 42 can be spaced apart from the battery 21, or the second limiting part 42 can be attached to the battery 21, and the specific adjustment can be made according to the actual situation.

[0068] For example, such as Figure 4 As shown, the first limiting part 41 is engaged between two second protrusions 1131. The second protrusions 1131 can guide the first limiting part 41 to slide, ensuring that the first limiting part 41 can move to a preset position and stably abut against the housing 11 and the battery 21.

[0069] In some embodiments, the housing 10 includes a housing 11 and a cover 1213. The housing 11 is provided with a receiving groove 101, and the cover 12 is movably connected to the housing 11. The cover 12 is used to open or close the opening 1011 of the receiving groove 101. It is understood that the cover 12 can close the opening 1011, thereby protecting the circuit board 30 and the battery 21 inside the receiving groove 101.

[0070] For example, the cover 12 and the housing 11 can be movably connected in the following ways: the cover 12 is slidably connected to the housing 10, or the cover 12 is detachably connected to the housing 10, or the cover 12 is rotatably connected to the housing 10.

[0071] In some embodiments, a connecting portion 13 is provided on the outer periphery of the outer casing 10. The connecting portion 13 is used to connect to the door body so as to realize the connection between the outer casing 10 and the door body. The connecting portion 13 protrudes from the outer casing 10 and can abut against the surface of the door body so as to realize the positioning of the new battery structure relative to the door body.

[0072] For example, the connecting part 13 can be fastened to the door body by fasteners such as screws and bolts, thereby improving the connection stability between the battery structure and the door body.

[0073] For example, the connecting portion 13 may be an annular connecting portion 13, which is disposed around the outer periphery of the housing 11.

[0074] like Figure 2 , Figure 3 and Figure 5 As shown, the battery structure further includes a reinforcing member 50, which is stacked with the connecting portion 13. By stacking the connecting portion 13 and the reinforcing member 50, the structural strength of the connecting portion 13 is improved, preventing the connecting portion 13 from being damaged by external forces.

[0075] For example, the reinforcement 50 may be one or more.

[0076] For example, the reinforcing member 50 may be made of metal materials such as stainless steel or iron, or it may be made of alloy materials or composite materials.

[0077] For example, the shape of the reinforcing member 50 can match the shape of the connecting part 13. The reinforcing member 50 and the connecting part 13 can be stacked sequentially on the door body. The reinforcing member 50 stably supports the connecting part 13, thereby improving the structural strength of the connecting part 13. For example Figure 3 As shown, the reinforcing member 50 can be the same annular reinforcing member 50 as the connecting part 13. The reinforcing member 50 is arranged around the outer periphery of the housing 11 and stacked with the connecting part 13. Fasteners such as screws and bolts can pass through the connecting part 13 and the reinforcing member 50 in sequence and be fastened to the door body. This facilitates the installation of the reinforcing member 50 on the door body and helps to stably position the reinforcing member 50 between the connecting part 13 and the door body, thereby improving the structural strength of the connecting part 13. Of course, in other embodiments, the reinforcing member 50 can also be a non-annular reinforcing member 50. The specific design can be adjusted according to the actual situation and is not limited here.

[0078] like Figure 2 As shown, further, the outer periphery of the outer casing 10 is provided with a snap-fit ​​portion 14, which is spaced apart from the connecting portion 13. The reinforcing member 50 is snapped between the snap-fit ​​portion 14 and the connecting portion 13. It can be understood that the snap-fit ​​of the reinforcing member 50 between the snap-fit ​​portion 14 and the connecting portion 13 can limit the position of the reinforcing member 50, so that the reinforcing member 50 is stably abutted against the connecting portion 13, thereby improving the structural strength of the connecting portion 13.

[0079] For example, such as Figure 2 As shown, the outer periphery of the housing 11 is provided with multiple snap-fit ​​parts 14, which can be spaced apart, and the reinforcing member 50 is stably snapped between each snap-fit ​​part 14 and the connecting part 13.

[0080] This utility model embodiment also provides a smart door, which includes the battery structure described in any of the preceding embodiments. It is understood that a smart door with the battery structure described above is suitable for situations where there is no pre-existing electrical potential in the house and it is inconvenient to modify the wiring, thus improving the adaptability of the smart door.

[0081] The above are merely specific embodiments of this utility model, but the protection scope of this utility model is not limited thereto. Any person skilled in the art can easily conceive of various equivalent modifications or substitutions within the technical scope disclosed in this utility model, and these modifications or substitutions should all be covered within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope of the claims.
