[0047] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, not the entire structure.

[0048] In the description of this utility model, unless otherwise explicitly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components.

[0049] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0050] In the description of this embodiment, the terms "upper," "lower," "right," etc., refer to the orientation or positional relationship shown in the accompanying drawings. They are used only for ease of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. In addition, the terms "first" and "second" are only used for distinction in description and have no special meaning.

[0051] Referring to Figures 1 to 5, this embodiment provides a battery structure, which includes a housing 100, a battery 200, a snap-fit ​​assembly 300, and a magnetic suction component 500.

[0052] Specifically, the housing 100 is provided with an electrical connection surface 121, on which a spring pin 101 is provided; the latching assembly 300 is provided on the housing 100, and the latching assembly 300 includes a latching member 310 and a release member 320; wherein, the spring pin 101 is used for electrical connection with the host, the latching member 310 is used for latching with the host, and the release member 320 is used for pushing the latching member 310 to disengage from the host.

[0053] Specifically, the battery 200 and the magnetic component 500 are both located inside the housing 100, and the magnetic component 500 is used to attract the main unit.

[0054] For example, the process of installing the battery structure onto the main unit is as follows: Align the latching member 310 with the corresponding latching position on the main unit, and bring the battery structure close to the main unit. This allows the magnetic member 500 to engage with the main unit, the latching member 310 to engage with the main unit, and the spring pin 101 to form an electrical connection with the main unit. This facilitates the connection between the battery structure and the main unit, effectively preventing connection failure. Furthermore, the engagement of the magnetic member 500 with the main unit ensures a stable and reliable electrical connection between the spring pin 101 and the main unit. It is understood that the battery 200 can form an electrical connection with the spring pin 101 indirectly or directly. Additionally, the battery structure can be easily separated from the main unit by pushing the latching member 310 with the unlocking member 320 to disengage the latching member 310 from the main unit. It is understood that to ensure the latching member 310 is properly engaged with the main unit and that the spring pin 101 is electrically connected to the main unit, the housing 100 can be pressed against the main unit during the installation of the battery structure.

[0055] For example, the host device includes, but is not limited to, rotating gimbals or brackets for electronic devices such as drones, cameras, and mobile phones, and remote controllers.

[0056] For example, multiple spring pins 101 are provided. The spring pins 101 can be arranged in a matrix. Multiple spring pins 101 can be integrated onto a single body. The spring pins 101 can be integrated onto a single body by means of bolt fastening or adhesive bonding.

[0057] For example, the snap-fit ​​assembly 300 has at least one, such as two, and is symmetrically arranged along a first direction. The first direction can be the length direction of the battery structure.

[0058] In one feasible implementation, as shown in Figures 2 to 4, both the latching member 310 and the unlocking member 320 are slidably connected to the housing 100 along a first direction. The latching assembly 300 further includes an elastic member 330, which is disposed between the housing 100 and the latching member 310. The elastic member 330 ensures that the latching member 310 always has a tendency to slide away from the unlocking member 320 along the first direction. The unlocking member 320 is used to push the latching member 310 against the elastic member 330 along the first direction, disengaging it from the main unit. Exemplarily, during the installation of the battery structure onto the main unit, the latching member 310 is compressed by the corresponding latching position of the main unit, and after moving along the first direction to make way for the corresponding latching position of the main unit, the latching member 310 resets under the action of the elastic member 330 and latches back into place at the corresponding latching position of the main unit. It is understood that the elastic member 330 can stably maintain the latching member 310 in contact with the corresponding latching position of the main unit, ensuring a stable and reliable connection. For example, when separating the battery structure from the main unit, pressing the release member 320 causes the release member 320 to push the latching member 310 to move along the first direction and disengage from the corresponding latching position on the main unit. The latching member 310 also compresses the elastic member 330, thus separating the battery structure from the main unit. After the battery structure is separated from the main unit, the latching member and the release member 320 reset under the action of the elastic member 330, facilitating operation.

[0059] Specifically, the housing 100 is provided with a sliding groove 122 and a through hole 123 communicating with the sliding groove 122. The through hole 123 is disposed through the electrical connection surface 121. The fastening member 310 includes a sliding part 311 slidably disposed in the sliding groove 122 and a fastening part 312 connected to the sliding part 311. The fastening part 312 passes through the through hole 123. The sliding groove 122 extends along a first direction. In this embodiment, the sliding part 311 is guided to move by the sliding groove 122, so that the fastening member 310 can slide stably relative to the housing 100 along the first direction. The fastening part 312 passes through the through hole 123, which facilitates observation of the position of the fastening part 312 relative to the host, and makes it easier to fasten the fastening member to the corresponding fastening position of the host.

[0060] For example, the snap-fit ​​portion 312 can be in an inverted shape for easy snap-fit.

[0061] For example, the groove 122 and the perforation 123 are provided in a one-to-one correspondence with the snap fastener assembly 300.

[0062] For example, the perforation 123 extends through the electrical connection surface 121 along a second direction. The second direction can be the height direction of the battery structure.

[0063] In one feasible implementation, as shown in Figures 2 to 4, the sliding part 311 includes a first sliding part 3111 and a second sliding part 3112 connected in sequence. The first sliding part 3111 and the second sliding part 3112 are arranged in parallel, that is, the sliding part 311 is set in a stepped shape, which effectively ensures the compactness of the battery structure.

[0064] Specifically, the first sliding part 3111 is slidably inserted into the slide groove 122 so that the fastener 310 can slide stably relative to the housing 100 along the first direction.

[0065] In this embodiment, the fastener 310 and the unfastener 320 can be separate or integrated; this embodiment does not impose any limitations.

[0066] Specifically, the unfastener 320 has a stepped surface 321 and an overlapping portion 322 on the stepped surface 321. The overlapping portion 322 is located along the second direction on the side of the sliding portion 311 where the latching portion 312 is located.

[0067] Taking the separate design of the fastener 310 and the unfastener 320 as an example, the stepped surface 321 abuts against the second sliding part 3112 along the first direction, and the overlapping part 322 abuts against the second sliding part 3112 along the second direction, so as to realize the limiting cooperation between the unfastener 320 and the fastener 310 along the first and second directions, so that the unfastener 320 can stably push the fastener 310 to slide relative to the housing 100 along the first direction.

[0068] For example, the overlapping part 322 and the second sliding part 3112 can be fixed together by adhesive bonding to ensure the synchronous sliding of the unfastening member 320 and the fastening member 310, effectively preventing the overlapping part 322 from detaching from the second sliding part 3112, and effectively preventing the unfastening member 320 and the fastening member 310 from sliding and getting stuck.

[0069] Taking the integrated design of the fastener 310 and the unfastener 320 as an example, the stepped surface 321 is connected to the second sliding part 3112 as a whole, and the overlapping part 322 is connected to the second sliding part 3112 as a whole, so that the unfastener 320 can stably push the fastener 310 to slide relative to the housing 100 along the first direction.

[0070] In one feasible implementation, the side of the overlapping portion 322 away from the sliding portion 311 along the second direction can abut against the housing 100. With the overlapping portion 322 abutting against the second sliding portion 3112 along the second direction, the unfastening member 320 can push the fastening member 310 to slide relative to the housing 100 more stably along the first direction.

[0071] Specifically, a limiting member 400 may be provided inside the housing 100, and a guide groove is formed between the limiting member 400 and the housing 100. The second sliding part 3112 and the overlapping part 322 pass through the guide groove and are guided by the guide groove. This allows the unlocking member 320 and the fastening member 310 to move more stably along the first direction, preventing the unlocking member 320 and the fastening member 310 from moving in any direction other than the first direction. The limiting member 400 is provided in a one-to-one correspondence with the fastening assembly.

[0072] For example, the limiting member 400 can be plate-shaped to prevent positional interference with the battery 200 and effectively ensure the compactness of the battery structure. The limiting member 400 can be formed by bending sheet metal. Specifically, the limiting member 400 includes a U-shaped plate 410 and ear plates 420 at both ends of the U-shaped plate 410. The ear plates 420 can be connected to the housing 100 by bolts. The ear plates 420 have grooves for the bolts to be recessed into, preventing positional interference between the bolts and the battery 200.

[0073] In one feasible implementation, as shown in FIG3, the first sliding part 3111 is provided with sliding protrusions 3113 on both sides along the second direction. The sliding protrusions 3113 slide in contact with the slide groove 122 to prevent the contact area between the first sliding part 3111 and the slide groove 122 from being too large, which would affect the sliding of the fastener 310 relative to the housing 100.

[0074] For example, the first sliding portion 3111 has at least one sliding protrusion 3113 on both sides along the second direction, for example, two protrusions are arranged side by side.

[0075] In one feasible implementation, as shown in Figures 2 and 3, the first sliding part 3111 has a protrusion 313 at one end away from the second sliding part 3112 along the first direction. The protrusion 313 passes through the elastic member 330 so that the elastic member 330 is stably compressed by the first sliding part 3111 along the first direction.

[0076] In one feasible implementation, as shown in Figures 4 and 5, the release element 320 includes a pressing part 323. The pressing part 323 has limiting protrusions 324 on both sides along a third direction. The housing 100 has a limiting channel 112. The pressing part 323 is located within the limiting channel 112. One end of the limiting channel 112 within the housing 100 forms a limiting engagement with the limiting protrusions 324 along a first direction and a second direction, preventing the release element 320 from detaching from the housing 100. The pressing part 323 has a stepped surface 321. The third direction can be the width direction of the battery structure. In this embodiment, pressing the pressing part 323 along the first direction allows the release element 320 to stably push the latching element 310 relative to the housing 100, facilitating disengagement from the main unit.

[0077] In this embodiment, referring to Figures 1, 2 and 5, the housing 100 may include a main housing 110 and a top cover 120. A sliding groove 122 is formed between the main housing 110 and the top cover 120. The top cover 120 is provided with a through hole 123. An electrical connection surface 121 is provided on the top cover 120. The battery 200 is provided inside the main housing 110, which facilitates the assembly of the snap-fit ​​components and the molding and manufacturing of the housing 100.

[0078] For example, the top cover 120 is disposed on the top of the main housing 110.

[0079] For example, the block integrating the spring pin 101 can be fixed to the main shell 110, the top cover 120 or the battery 200, or it can be fixed to other components, which is not limited in this application.

[0080] For example, the top cover 120 is located at the top of the main shell 110 along the second direction.

[0081] For example, the main shell 110 has a recessed groove 111 at its top end along the second direction, and the top cover 120 is disposed in the recessed groove 111.

[0082] For example, the limiting channel 112 is provided on the main housing 110.

[0083] For example, the top cover 120 can be made of metal.

[0084] For example, the top cover 120 and the main housing 110 can be connected by at least one of adhesive bonding and bolting.

[0085] Specifically, a cover plate 130 is provided between the main shell 110 and the top cover 120, and a first mounting groove is formed between the cover plate 130 and the top cover 120. The elastic element 330 is disposed in the first mounting groove, which facilitates the positioning and assembly of the elastic element 330 and facilitates the molding and manufacturing of the shell 100. The cover plate 130 can be fixed to the top cover 120 by bolt connection.

[0086] For example, the snap-fit ​​assembly includes at least one elastic element 330, such as two elastic elements 330 arranged side by side, with each elastic element 330 corresponding to a first mounting slot.

[0087] For example, the elastic element 330 includes, but is not limited to, a spring.

[0088] Specifically, the housing 100 may also include a bottom cover 140, which covers the bottom of the main housing 110. An installation cavity is formed between the main housing 110 and the bottom cover 140, and the battery 200 is disposed in the installation cavity to facilitate the assembly of the battery 200.

[0089] For example, the bottom cover 140 can be made of metal.

[0090] For example, the bottom cover 140 and the main housing 110 can be connected by at least one of adhesive bonding and bolting.

[0091] In one feasible implementation, the top cover 120 is provided with a second mounting groove for accommodating the magnetic component 500 on the side opposite to the electrical connection surface 121 along the second direction; or the bottom of the recess 111 of the main shell 110 is provided with a third mounting groove for accommodating the magnetic component 500; or the top cover 120 is provided with a second mounting groove for accommodating the magnetic component 500 on the side opposite to the electrical connection surface 121 along the second direction, and the bottom of the recess 111 of the main shell 110 is provided with a third mounting groove for accommodating the magnetic component 500, so as to ensure the compactness of the battery structure.

[0092] For example, at least one magnetic member 500 is provided, for example, two to four are provided at intervals, and the magnetic member 500 is provided in a one-to-one correspondence with the second mounting slot and the third mounting slot.

[0093] For example, the magnetic component 500 can be fixed to the top cover 120 by adhesive bonding.

[0094] In one feasible implementation, as shown in FIG5, the battery structure further includes a heat sink 600, which is disposed inside and connected to the housing 100. The heat dissipated by the battery 200 can be quickly conducted to the housing 100 through the heat sink 600 to accelerate the heat dissipation of the battery structure.

[0095] For example, the heat sink 600 can be made of metal.

[0096] For example, the heat sink 600 may be in the shape of a block or a plate.

[0097] Specifically, the heat sink 600 is connected to at least one of the top cover and the bottom cover 140. For example, the heat sink 600 can be L-shaped, including a first plate portion 610 and a second plate portion 620. The first plate portion 610 is located on top of the battery 200 and can be connected to the top cover 120, while the second plate portion 620 is located on the periphery of the battery 200 and can be connected to the bottom cover 140. This provides a large heat dissipation area, accelerating heat dissipation. The first plate portion 610 is connected to the top cover 120, which is made of metal. The material of the part where the host unit mates with the electrical connection surface 121 can also be made of metal to accelerate heat dissipation and assist in heat dissipation of the host unit. It can be understood that the heat from the host unit can be sequentially conducted to the top cover 120, the heat sink 600, and the bottom cover 140 for heat dissipation. In some embodiments, thermally conductive materials may be applied between the first plate portion 610 and the battery 200, between the first plate portion 610 and the top cover 120, between the second plate portion 620 and the battery 200, and between the second plate portion 620 and the bottom cover 140 to further enhance the heat dissipation capacity of the battery 200. The thermally conductive materials may be thermally conductive solder paste, thermally conductive silicone grease, thermally conductive adhesive, thermally conductive gel, thermally conductive silicone, etc.

[0098] In this embodiment, referring to Figures 5 and 6, the battery structure further includes a motherboard 710, to which the battery 200 is electrically connected. The motherboard 710 can be fixed to the bottom cover 140 for easy assembly.

[0099] In one feasible embodiment, the battery structure further includes a support plate 740, which is located above the main board 710 and fixedly mounted to the bottom cover 140; the battery 200 is fixed on the support plate 740 for easy assembly.

[0100] For example, the motherboard 710 can be a PCB circuit board.

[0101] In one feasible implementation, the battery structure further includes a flexible circuit board 720, which is electrically connected to the main board 710. A spring pin 101 is disposed on the flexible circuit board 720. The battery 200 is electrically connected to the spring pin 101 through the main board 710 and the flexible circuit board 720, which facilitates assembly.

[0102] In one feasible implementation, the flexible circuit board 720 is further provided with a power button 730, which can control the connection between the battery 200 and the main unit. For example, the power button 730 may be located on the periphery of the main housing 110.
