[0044] In this document, the term "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this application. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0045] Please see Figure 1 and Figure 2 As shown, an expansion module 100 corresponding to a preferred embodiment of the present invention is used for a battery 200. The expansion module 100 includes: a module body 110; a conductive element 120 mounted on the module body 110; and an expansion unit 130 mounted on the module body 110 and electrically connected to the conductive element 120. The module body 110 is adapted to be plugged into the battery 200, and the conductive element 120 is connected to the positive and negative terminals of the battery 200.

[0046] This utility model provides an expansion module 100, whose module body 110 can be installed on the battery 200, and its conductive parts 120 are connected to the positive and negative terminals of the battery 200, so that the battery 200 can supply power to the expansion unit 130 installed on the module body 110, thereby expanding the functionality. In addition, the module body 110 and the battery 200 are plugged in and connected, which is convenient for disassembly and assembly, so as to replace the expansion module 100 with different expansion units 130 to meet different usage needs.

[0047] Furthermore, referring to Figures 3 to 5 As shown, the module body 110 includes a main body 111 and a snap-fit ​​portion. The conductive element 120 and the expansion unit 130 are both mounted on the main body 111, and the snap-fit ​​portion protrudes from the main body 111. The battery 200 includes a housing 210, which has a recessed slot adapted to the snap-fit ​​portion. The snap-fit ​​portion is adapted to be embedded and fixed in the slot. The slot is recessed inward from the top of the housing 210, and the snap-fit ​​portion protrudes from the bottom of the main body 111. In one embodiment, the slot extends horizontally to both sides of the housing 210. The cross-section of the slot perpendicular to the extension direction is U-shaped, and at least one side of the slot is open in the horizontal direction. The snap-fit ​​portion is a long strip-shaped structure whose length direction is parallel to the extension direction of the slot. The snap-fit ​​portion is adapted to the slot and is adapted to be inserted into the slot from its open side along the extension direction of the slot, and is limited by the slot in the vertical direction.

[0048] However, with the above structure, the slot and the snap-fit ​​part are complex and the processing is cumbersome. Furthermore, the disassembly and assembly efficiency of the module body 110 and the outer shell 210 is low. Preferably, in this embodiment, the slot extends inward from the top of the outer shell 210 to a certain depth, and the snap-fit ​​part is directly inserted into the slot in the vertical direction to simplify the structure and improve the disassembly and assembly efficiency.

[0049] Specifically, the slot includes a first slot 211 recessed inward from the top of the outer shell 210, and the outer shell 210 is provided with at least one first slot 211 on each side in the first horizontal direction. The engaging portion includes a first engaging portion 112 extending downward from the bottom of the main body portion 111, and the main body portion 111 is provided with at least one first engaging portion 112 on each side in the first horizontal direction. The first engaging portion 112 corresponds one-to-one with the first slot 211.

[0050] Furthermore, the battery 200 includes a positive terminal 221 and a negative terminal 222. Preferably, the positive terminal 221 and the negative terminal 222 are respectively fixed in different first slots 211. Since existing batteries 200 usually have a groove structure for mounting terminals, by adopting the above structure, the groove on the existing battery 200 is directly utilized to engage with the engaging part, avoiding major modifications to the outer casing 210 of the battery 200 and effectively reducing costs. The first slot 211 extends along a first horizontal direction and penetrates to the side wall of the outer casing 210. The first engaging part 112 engages between the two inner walls of the first slot 211 in a second horizontal direction, which is perpendicular to the first horizontal direction. The first slot 211 with the above structure increases the degree of exposure of the terminals, facilitating connection with the electric winch via a wire clamp. It also facilitates observation of the engagement degree of the first engaging part 112 and the first slot 211, ensuring that they are properly engaged.

[0051] Furthermore, the first slot 211 has inwardly recessed mounting holes 213 on both sidewalls in the second horizontal direction. The mounting holes 213 on the two sidewalls are coaxial and have a through structure in their axial direction. The positive terminal 221 and / or the negative terminal 222 are adapted to the mounting holes 213, with one end fixedly inserted into one mounting hole 213 and the other end fixedly inserted into the other mounting hole 213. When the terminal is installed in place, the outer periphery of the terminal does not protrude from the slot opening and open side of the first slot 211, so as to prevent the module body 110 installed on the housing 210 from contacting the terminal, effectively protecting the terminal.

[0052] Furthermore, a gap for accommodating the conductive member 120 is formed between the periphery of the positive terminal 221 and the side wall of the first slot 211, and a gap for accommodating the conductive member 120 is formed between the periphery of the negative terminal 222 and the side wall of the first slot 211. Two conductive members 120 are fixed to the bottom of the main body 111, corresponding respectively to the positive terminal 221 and the negative terminal 222. Preferably, the conductive element 120 is a metal spring with a V-shaped or U-shaped structure. During the process of inserting the expansion module 100 into the outer casing 210 of the battery 200, the conductive element 120 is obstructed by the positive terminal 221 and / or the negative terminal 222, allowing it to retract inward along the first horizontal direction to avoid obstructing the connection of the expansion module 100. This also provides the conductive element 120 with a counterforce against the positive terminal 221 and / or the negative terminal 222, ensuring close contact while simultaneously hindering the expansion module 100 in the height direction of the battery 200, making it less likely for the expansion module 100 to detach from the outer casing 210. Furthermore, the conductive element 120 preferably contacts the terminal in the middle or approximately the middle region of the axial direction to further improve the tightness of the connection.

[0053] In a preferred embodiment, the slot includes a second slot 212 recessed inward from the top of the outer casing 210, and the outer casing 210 has at least one second slot 212 on each of its two sides in the second horizontal direction. The engaging portion includes a second engaging portion 113 extending downward from the bottom of the main body 111, and the main body 111 has at least one second engaging portion 113 on each of its two sides in the second horizontal direction, with each second engaging portion 113 corresponding to a second slot 212. By adopting the above structure, the tightness of the connection between the module body 110 and the outer casing 210 can be further improved. Admittedly, in other embodiments, a threaded connector (not shown) can also be provided between the outer casing 210 and the module body 110, which provides better reliability after connection compared to the snap-fit ​​fixing.

[0054] Preferably, the recessed depth of the first slot 211 is the same as the protruding depth of the first engaging portion 112. When the module body 110 and the outer shell 210 are engaged, the bottom of the first engaging portion 112 contacts the bottom of the first slot 211, and the bottom of the main body 111 contacts the top of the outer shell 210. The recessed depth of the second slot is the same as the protruding depth of the second engaging portion 113. When the module body 110 and the outer shell 210 are engaged, the bottom of the second engaging portion 113 contacts the bottom of the second slot 212, and the bottom of the main body 111 contacts the top of the outer shell 210. Preferably, the second slot 212 can extend along the second horizontal direction and penetrate to the side wall of the outer shell 210, facilitating observation of the engagement degree of the second engaging portion 113 and the second slot 212, ensuring that they are engaged in place, and making the engagement process smoother. Preferably, the dimensions of the first slot 211 and the second slot 212 in the second horizontal direction are different to prevent mistaken connection and ensure reliable contact between the terminal and the conductive element 120. Furthermore, the second slots 212 located on both sides of the housing 210 can be staggered in the first horizontal direction to further prevent mistaken connection, ensuring reliable contact between the conductive element 120 corresponding to the positive terminal 221 and the conductive element 120 corresponding to the negative terminal 222. Of course, in other embodiments, an indicator structure can also be provided to indicate the correct mating position.

[0055] Furthermore, in one embodiment, the bottom of the main body 111 and the top of the outer shell 210 are both flat to facilitate the processing and forming of the module body 110 and the outer shell 210. Admittedly, in other embodiments, one of the tops of the main body 111 and the outer shell 210 is a recessed structure and the other is a protruding structure, so that the main body 111 and the outer shell 210 are fitted together, further improving the tightness of the connection between the two.

[0056] Furthermore, the expansion unit 130 includes a first expansion unit 131 electrically connected to the conductive element 120. The main body 111 has a hollow structure with a first wire inside. The conductive element 120 and the first expansion unit 131 are at least partially located within the main body 111, and the two ends of the first wire are electrically connected to the conductive element 120 and the first expansion unit 131, respectively. In this embodiment, the first expansion unit 131 is a charging and discharging unit. The main body 111 has a mounting port, and the first expansion unit 131 has an interface for installation in the mounting port. The interface includes, but is not limited to, a USB interface and a TYPE interface, for connecting external cables to achieve charging and discharging functions, i.e., it can function as a power bank. In addition, due to usage scenario limitations, the battery 200 is prone to contact with liquids. By adopting the above structure, the number of interfaces on the battery 200 can be reduced, improving the sealing performance of the battery 200.

[0057] Furthermore, the expansion unit 130 also includes a second expansion unit 132 electrically connected to the conductive element 120. The second expansion unit 132 includes, but is not limited to, at least one of a lighting lamp, a spotlight, and a fan. A second wire is provided inside the main body 111, one end of which is electrically connected to the conductive element 120, and the other end extends out of the main body 111 and is electrically connected to the second expansion unit 132. Different second expansion units 132 can be provided on the main body 111 of different expansion modules 100 to meet different functional requirements.

[0058] Preferably, a switch unit 140 is provided outside the main body 111. The switch unit 140 is electrically connected between the second extension unit 132 and the conductive member 120 to open or close the second extension unit 132 as needed. Preferably, a bracket 150 is mounted on the top of the main body 111, and the second extension unit 132 is mounted on the bracket 150 to improve the stability of the second extension unit 132 after installation. The bracket 150 is preferably a foldable structure, so that it can be unfolded out of the main body 111 when the second extension unit 132 is needed, and can be folded into the main body 111 when the second extension unit 132 is not needed, thereby reducing the space occupied and adjusting the position.

[0059] Furthermore, referring to Figure 1 , Figure 2 and Figure 6 As shown, this utility model also provides a battery device, including the aforementioned expansion module 100 and battery 200. The expansion module 100 is adapted to be plugged into and electrically connected to the battery 200. The battery 200 includes a housing 210, a battery body 230, a battery protection board 240, a positive terminal 221, and a negative terminal 222. The battery body 230 and the battery protection board 240 are installed inside the housing 210, and the battery protection board 240 is electrically connected to the battery body 230. The positive terminal 221 and the negative terminal 222 are installed outside the housing 210.

[0060] Specifically, the outer casing 210 consists of an outer casing body 214 and an end cap 215. The top of the outer casing body 214 has a pick-and-place opening 2141. The battery body 230 and the battery protection board 240 are installed inside the battery body 230 through the pick-and-place opening 2141. The end cap 215 is detachably fixed to the top of the outer casing body 214 to close the pick-and-place opening 2141. The end cap 215 and the outer casing body 214 can be fastened together using threaded fittings. The first slot 211 and the second slot 212 are both formed on the end cap 215. The battery protection board 240 is located between the battery body 230 and the end cap 215 to facilitate electrical connection with the positive terminal 221 and the negative terminal 222 on the end cap 215.

[0061] Preferably, the battery 200 further includes a power display unit 250 mounted outside the housing 210. The power display unit 250 is electrically connected to the battery protection board 240 and is suitable for displaying the power level of the battery 200, ensuring that the user can obtain the power level information of the battery 200 in a timely manner. The power display unit 250 is preferably mounted on the top of the end cover 215 and does not protrude relative to the top surface of the end cover 215, so that it has sufficient installation space. The power display unit 250 is easier to electrically connect to the battery protection board 240 and is also easier for the user to observe during the power supply to the electric winch.
