[0024] In all the examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not as limitations. Therefore, other examples of exemplary embodiments may have different values.

[0025] It should be noted that similar labels and letters in the following figures indicate similar items; therefore, once an item is defined in one figure, it does not need to be discussed further in subsequent figures.

[0026] The battery 100 according to an embodiment of this application will now be described in detail with reference to the accompanying drawings.

[0027] like Figures 1 to 5 As shown, the battery 100 according to an embodiment of this application includes: a housing 10, a locking tongue 20, a rotating assembly 30, and a pull ring 40.

[0028] Specifically, the outer casing 10 includes a main body 11 and a connecting part 12. The main body 11 contains a battery cell, and the connecting part 12 has a mounting cavity and an assembly port 1211 communicating with the mounting cavity. The locking tongue 20 is movably mounted on the assembly port 1211. The locking tongue 20 can retract into the mounting cavity to be in an unlocked position and extend out of the mounting cavity to be in a locked position. The rotating assembly 30 is rotatably disposed in the mounting cavity about a first axis. The rotating assembly 30 is pultrusively connected to the locking tongue 20 to drive the locking tongue 20 to extend and retract along the assembly port 1211. The pull ring 40 is disposed on the outside of the connecting part 12 and is connected to the rotating assembly 30 to drive the rotating assembly 30 to rotate under the action of external force.

[0029] In some embodiments, such as Figures 1 to 5As shown, the battery 100 includes a casing 10, a battery cell, a locking tongue 20, a rotating assembly 30, and a pull ring 40. The casing 10 includes a main body 11 and a connecting part 12 distributed along its length. The main body 11 has a receiving cavity suitable for accommodating the battery cell, which is installed within the receiving cavity. The connecting part 12 has a mounting cavity, and its side wall has a through-hole assembly port 1211 communicating with the mounting cavity. Each assembly port 1211 corresponds to a locking tongue 20, which is movably disposed on the connecting part 12 along the axial direction of the assembly port 1211, allowing the locking tongue 20 to switch between an unlocked position and a locked position; that is, the locking tongue 20 can retract into the mounting cavity to the unlocked position and extend out of the mounting cavity to the locked position. The extension and retraction of the latch 20 is used to lock and unlock the battery 100 to an external device. When the latch 20 is extended to the locked position, it engages with the slot of the external device to lock the battery 100 to the external device. When the latch 20 is retracted to the unlocked position, it disengages from the slot of the external device, allowing the battery 100 to be removed from the external device. The rotating assembly 30 is rotatably disposed in the mounting cavity about a first axis extending along the length of the housing 10. The rotating assembly 30 is drively connected to the latch 20 to drive the latch 20 to extend and retract axially along the mounting opening 1211.

[0030] The pull ring 40 is located on the outside of the connecting part 12 and is connected to the rotating assembly 30. It is used to drive the rotating assembly 30 to rotate under the action of external force. When removing the battery 100, the user rotates the pull ring 40 to drive the rotating assembly 30 to rotate around the first axis, thereby causing the latch 20 to retract to the unlocked position. After the latch 20 retracts, the user can remove the battery 100 from the external device by pulling the pull ring 40.

[0031] Therefore, according to the battery 100 provided in this embodiment, the pull ring 40 can drive the rotating component 30 to rotate, and the rotating component 30 can drive the locking tongue 20 to extend and retract, so that the locking tongue 20 can flexibly switch between the unlocked position and the locked position, thereby realizing convenient locking and unlocking of the battery 100 and the external device, which can effectively improve the battery swapping efficiency, and the transmission is reliable and the service life is long, which can be adapted to frequent battery swapping scenarios; moreover, after the battery 100 is unlocked from the external device, the battery 100 can be removed from the external device by pulling the pull ring 40, without the need for additional tools, and the installation and removal of the battery 100 can be completed with one hand, further simplifying the disassembly process.

[0032] In some specific embodiments of this application, the rotating assembly 30 is eccentrically provided with a transmission pin 331 at one end away from the main body 11, and the connecting part 12 is provided with an arc-shaped groove 1221 on the side away from the main body 11. The transmission pin 331 is rotatably disposed in the arc-shaped groove 1221 around the first axis. The pull ring 40 is connected to the transmission pin 331. The two ends of the arc-shaped groove 1221 in the circumferential direction are used to limit the rotation angle of the rotating assembly 30 by engaging with the transmission pin 331.

[0033] Specifically, such as Figure 2 As shown, the connecting part 12 has two through-hole arc-shaped grooves 1221 on its side wall away from the main body 11. The two arc-shaped grooves 1221 extend circumferentially along the rotating assembly 30 and are arranged opposite each other radially along the rotating assembly 30. Two transmission pins 331 are fixedly connected to one end of the rotating assembly 30 away from the main body 11. The transmission pins 331 correspond one-to-one with the arc-shaped grooves 1221, and each transmission pin 331 is rotatably disposed in the corresponding arc-shaped groove 1221 around a first axis. The first end of the pull ring 40 is connected to one of the transmission pins 331, and the second end of the pull ring 40 is connected to the other transmission pin 331. The two circumferential ends of the arc-shaped grooves 1221 are used to limit and abut against the corresponding transmission pins 331 to restrict the rotation angle of the rotating assembly 30.

[0034] When the pull ring 40 is rotated in the forward direction, the pull ring 40 drives the transmission pin 331 to rotate in the forward direction along the arc groove 1221 around the first axis. The transmission pin 331 drives the rotating assembly 30 to rotate synchronously, thereby driving the locking tongue 20 to retract. When the transmission pin 331 rotates to the first end of the arc groove 1221, it is limited and the rotating assembly 30 stops rotating. At this time, the locking tongue 20 reaches the maximum retracted position. When the pull ring 40 is rotated in the reverse direction to reset, the transmission pin 331 rotates in the reverse direction along the arc groove 1221. At the same time, the rotating assembly 30 rotates in the reverse direction, and the locking tongue 20 extends out of the mounting cavity. When the transmission pin 331 rotates to the second end of the arc groove 1221, the transmission pin 331 is limited and abuts against the second end of the arc groove 1221, the rotating assembly 30 stops rotating, and the locking tongue 20 reaches the maximum extended position.

[0035] In this embodiment, the rotation angle of the rotating component 30 can be limited by the circumferential ends of the arc groove 1221 abutting against the transmission pin 331, so that the locking tongue 20 moves within a predetermined stroke range, thereby effectively preventing the locking tongue 20 from disengaging from the assembly port 1211, preventing structural damage caused by excessive extension and retraction of the locking tongue 20, and improving the stability and reliability of operation.

[0036] According to one embodiment of this application, the connecting portion 12 is provided with a receiving groove 1222 on the outer side away from the main body portion 11, and the pull ring 40 is rotatably disposed on the transmission pin 331 around a second axis perpendicular to the first axis, so that the pull ring 40 can be selectively rotated to a receiving position stored in the receiving groove 1222, or rotated to an operating position protruding from the receiving groove 1222.

[0037] In other words, such as Figure 1 As shown, the connecting portion 12 has a receiving groove 1222 on its outer side away from the main body 11, which is suitable for accommodating the pull ring 40. The arc-shaped groove 1221 is located at the bottom of the receiving groove 1222. The pull ring 40 is rotatably disposed on the transmission pin 331 around a second axis perpendicular to the first axis, so that the pull ring 40 can switch between a retracted position and an operating position. When the pull ring 40 is in the retracted position, the pull ring 40 is basically parallel to the outer side of the connecting portion 12 away from the main body 11, and the entire pull ring 40 is retracted into the receiving groove 1222. When the pull ring 40 is in the operating position, the pull ring 40 is basically perpendicular to the outer side of the connecting portion 12 away from the main body 11, and at least a portion of the pull ring 40 is located on the outer side of the receiving groove 1222. After the battery 100 is installed, the pull ring 40 can be flipped to the storage position, so that the pull ring 40 is hidden in the receiving groove 1222, avoiding problems such as bumps and accidental contact caused by the pull ring 40 protruding; when it is necessary to remove or install the battery 100, the pull ring 40 can be flipped to the operating position, making it convenient for the user to apply external force to operate.

[0038] In this embodiment, the pull ring 40 of the battery 100 can be flipped for storage, which not only ensures convenient operation but also prevents the pull ring 40 from being damaged or accidentally touched when not in operation, thus improving the safety and compactness of the battery 100.

[0039] In some specific embodiments of this application, the receiving groove 1222 is configured as an annular structure so that the pull ring 40 can be flipped in different directions and stored in the receiving groove 1222.

[0040] Specifically, such as Figure 1 and Figure 2 As shown, the pull ring 40 has a semi-circular structure and can be rotated 180 degrees around the second axis. The receiving groove 1222 is set as a circular structure and is adapted to the pull ring 40. The two extreme positions of the pull ring 40 before and after rotating 180 degrees correspond to the first storage position and the second storage position, respectively. After the battery 100 is installed, flipping the pull ring 40 along the first direction will flip the pull ring 40 to the first storage position; flipping the pull ring 40 along the second direction will flip the pull ring 40 to the second storage position.

[0041] In this embodiment, the design of the annular receiving groove 1222 improves the flexibility of the pull ring 40 operation, adapts to the operating habits of different users, and ensures the stability of the pull ring 40 storage.

[0042] According to one embodiment of this application, the connecting part 12 includes: a housing 121, a first end of which is disposed on the main body 11, a second end of which is open, an assembly port 1211 disposed on the side wall of the housing 121, a guide groove 1212 suitable for guiding the latch 20 is provided on the inner wall of the housing 121 near the main body 11, and a rotating assembly 30 is rotatably disposed on the housing 121; a cover 122, a receiving groove 1222 and an arc-shaped groove 1221 are provided on the cover 122, and the cover 122 is provided with a through groove 1223 suitable for the pull ring 40 to pass through, and the cover 122 is fixedly connected to the second end of the housing 121 to close the opening of the housing 121.

[0043] In other words, such as Figures 2 to 5 As shown, the connecting part 12 is mainly composed of a housing 121 and a cover 122. The first end of the housing 121 can be integrally formed into the end of the main body 11. The first end of the housing 121 is open, and an assembly port 1211 is provided on the side wall of the housing 121 along its length. The inner wall of the housing 121 near the main body 11 has a guide groove 1212 adapted to the latch 20. For example, a first guide plate and a second guide plate are fixedly connected to the inner wall of the housing 121 near the main body 11, and the guide groove 1212 is defined between the first guide plate and the second guide plate. The latch 20 is movably disposed in the guide groove 1212 along its length. Both the receiving groove 1222 and the arc-shaped groove 1221 are provided on the cover 122, and the cover 122 is provided with a through groove 1223 extending along its thickness direction. The through groove 1223 is an elongated groove extending radially along the rotating assembly 30. The first end of the through groove 1223 communicates with the first arc-shaped groove 1221, and the second end communicates with the second arc-shaped groove 1221. After the latch 20, the rotating assembly 30 and the pull ring 40 are assembled, the pull ring 40 can pass through the through groove 1223, and then the cover 122 is fixed to the second end of the housing 121 by screws or the like.

[0044] In this embodiment, by providing a through groove 1223 on the cover 122, the latch 20, rotating assembly 30, and pull ring 40 can be installed into the housing 121 through the opening end of the housing 121 before the cover 122. After the pull ring 40 is connected to the rotating assembly 30, the cover 122 is fixed to the second end of the housing 121. Since the cover 122 is installed last, the opening end of the housing 121 provides unobstructed operating space in the early stage of assembly, which facilitates the sequential installation and interconnection of the latch 20, rotating assembly 30, and pull ring 40, reducing assembly difficulty and improving assembly efficiency.

[0045] In some specific embodiments of this application, the connecting part 12 is provided with two oppositely arranged mounting ports 1211, each of which is equipped with the locking tongue 20. The locking tongue 20 is slidably connected to the connecting part 12 along its length direction. The rotating assembly 30 includes: a rotating member 31, which is rotatably disposed in the mounting cavity around the first axis, and the pull ring 40 is connected to the rotating member 31; and a connecting rod 32, which is provided between the locking tongue 20 and the rotating member 31. The first end of the connecting rod 32 is eccentrically hinged to the rotating member 31 relative to the first axis, and the second end of the connecting rod 32 is hinged to the locking tongue 20.

[0046] Specifically, such as Figure 4 As shown, the battery 100 has two locking tongues 20, which are arranged opposite each other along the width direction of the outer casing 10. The side wall of the casing 121 has two mounting openings 1211 adapted to the two locking tongues 20. The casing 121 has two guide grooves 1212 adapted to the two locking tongues 20, and the two locking tongues 20 are slidably disposed in the corresponding guide grooves 1212 along their length direction. The rotating assembly 30 mainly consists of a rotating member 31 and a connecting rod 32. The rotating member 31 can be a rotating cam, and the outer contour of the rotating cam is formed into an oval shape. The rotating member 31 is rotatably disposed on the inner wall of the outer casing 10 near the main body 11 around a first axis, and the rotating member 31 is located between the two locking tongues 20. A connecting rod 32 is provided between the two locking tongues 20 and the rotating member 31. The first end of the connecting rod 32 is hinged to the outer periphery of the rotating member 31 in the long axis direction, and the first end of the connecting rod 32 is hinged to the end of the locking tongue 20 near the rotating member 31.

[0047] In this embodiment, the pull ring 40 is connected to the side of the rotating member 31 away from the main body 11. The rotating member 31, the connecting rod 32 and the locking tongue 20 form a crank-slider structure. The pull ring 40 drives the rotating member 31 to rotate under the action of external force. When the rotating member 31 rotates, the connecting rod 32 drives the two locking tongues 20 to extend and retract synchronously along the guide groove 1212, realizing the switching of the locking tongues 20 between the unlocked position and the locked position, which is convenient to operate.

[0048] According to one embodiment of this application, the rotating assembly 30 further includes: an adapter plate 33, the adapter plate 33 being fixedly connected to the rotating member 31 on the side near the pull ring 40, the radial dimension of the adapter plate 33 being larger than the radial dimension of the rotating member 31, and the transmission pin 331 being disposed on the side of the adapter plate 33 near the pull ring 40.

[0049] In this embodiment, as Figure 3 As shown, a transfer plate 33 is fixedly connected to the side of the rotating part 31 away from the main body 11. The radial dimension of the transfer plate 33 is larger than that of the rotating part 31, which can provide a more stable installation position for the transmission pin 331 and increase the rotation radius of the transmission pin 331, so that the external force of the pull ring 40 can increase the torque, thereby realizing labor-saving operation.

[0050] In some specific embodiments of this application, the battery 100 further includes an elastic reset member 50, which is disposed between the latch 20 and the inner wall of the connecting portion 12, and is used to provide the latch 20 with an elastic force that extends outward from the mounting cavity.

[0051] Specifically, such as Figure 4 As shown, the elastic reset member 50 is configured as a compression spring. The elastic reset member 50 can provide reset power for the extension action of the latch 20. When the pull ring 40 is pulled to retract the latch 20, the elastic reset member 50 is compressed and stores elastic potential energy. When the pull ring 40 is released, the elastic reset member 50 releases the elastic potential energy, pushes the latch 20 to extend out of the mounting cavity, and automatically locks the battery 100 without the need for manual operation by the user, further improving the convenience of disassembly and assembly.

[0052] The battery 100 provided in this embodiment, with the elastic reset member 50, enables the automatic reset of the locking tongue 20, simplifies the operation process, ensures the stability of the battery 100 locking, and improves the vibration resistance.

[0053] According to one embodiment of this application, the latch 20 is provided with a first mounting portion 21 at both ends in the width direction. The first mounting portion 21 is located in the mounting cavity. The housing 121 is provided with a second mounting portion 1213 corresponding to each of the first mounting portions 21 near the inner wall of the main body 11. The first mounting portion 21 and the corresponding second mounting portion 1213 are arranged opposite to each other in the length direction of the latch 20. The elastic reset member 50 is provided between the first mounting portion 21 and the corresponding second mounting portion 1213.

[0054] In other words, such as Figure 4As shown, the latch 20 has a first mounting portion 21 integrally formed at both ends of its width in the mounting cavity. A second mounting portion 1213 corresponding to each first mounting portion 21 is fixedly connected to the inner wall of the housing 121 near the main body 11. The first mounting portion 21 and the corresponding second mounting portion 1213 are arranged opposite each other in the length direction of the latch 20. A first protrusion is provided on the side of the first mounting portion 21 near the corresponding second mounting portion 1213, and a second protrusion is provided on the side of the second mounting portion 1213 near the corresponding first mounting portion 21. An elastic reset member 50 is provided between each first mounting portion 21 and each second mounting portion 1213. The first end of the elastic reset member 50 is sleeved on the first protrusion and abuts against the first mounting portion 21, and the second end of the elastic reset member 50 is sleeved on the second protrusion and abuts against the second mounting portion 1213. When the latch 20 is in the locked position, the first mounting part 21 abuts against the inner wall surface of the cover 122, the first protrusion and the second protrusion are spaced apart, and the elastic reset member 50 is in a partially compressed state; when the latch 20 is in the unlocked position, the elastic reset member 50 is compressed, and the distance between the first protrusion and the second protrusion support becomes smaller.

[0055] In this embodiment, two elastic reset members 50 are symmetrically arranged at both ends of the bolt 20 in the width direction, which can provide a uniform reset force to the bolt 20, avoid the bolt 20 from shifting or jamming due to uneven force, and ensure the smooth extension and retraction of the bolt 20.

[0056] In some specific embodiments of this application, the connecting portion 12 is provided with a handle groove 1224 on the outer side away from the main body portion 11, and one side of the handle groove 1224 is connected to the receiving groove 1222.

[0057] Specifically, the cover 122 has two handle grooves 1224 on the side away from the main body 11. The two handle grooves 1224 are symmetrically arranged about the second axis. The handle grooves 1224 can be located on the inner ring side of the annular receiving groove 1222. Each handle groove 1224 is connected to the receiving groove 1222 and is used to allow fingers to be inserted to pry up the pull ring 40.

[0058] In summary, according to the battery 100 provided in this embodiment, the pull ring 40 can drive the rotating component 30 to rotate, and the rotating component 30 can drive the locking tongue 20 to extend and retract, so that the locking tongue 20 can flexibly switch between the unlocked position and the locked position, thereby realizing convenient locking and unlocking of the battery 100 and the external device, which can effectively improve the battery swapping efficiency, and the transmission is reliable and the service life is long, which can be adapted to frequent battery swapping scenarios; moreover, after the battery 100 is unlocked from the external device, the battery 100 can be removed from the external device by pulling the pull ring 40, without the need for additional tools, and the installation and removal of the battery 100 can be completed with one hand, further simplifying the disassembly process.
