The anti-detachment hole is formed on the first anti-detachment part.

[0009] In an optional embodiment, the screw further has a head, the threaded segment and the head are respectively connected to both ends of the guide segment along the axial direction of the guide segment, the head is exposed outside the anti-loosening hole and the connecting hole, and can abut against the fixing bracket, the first anti-loosening part has a first guide surface, the first guide surface is disposed at one end of the first anti-loosening part along the axial direction of the anti-loosening hole near the head, and is disposed at the edge of the anti-loosening hole, the first guide surface is angularly disposed with respect to the radial direction along the anti-loosening hole, and is inclined in a direction away from the head.

[0010] In an optional embodiment, the anti-detachment portion includes a plurality of second anti-detachment portions, which are spaced apart circumferentially along the connecting hole, and each second anti-detachment portion protrudes at least partially from the hole wall of the connecting hole in the radial direction, and the plurality of second anti-detachment portions surround to form the anti-detachment hole.

[0011] In an optional embodiment, the wall of the connecting hole is provided with a plurality of clearance grooves, the plurality of clearance grooves are arranged at intervals along the circumference of the connecting hole, each clearance groove is in communication with the connecting hole, and each of the second anti-detachment parts passes through one of the clearance grooves and moves radially relative to the clearance groove along the connecting hole.

[0024] Reference Figure 1 as well as Figure 2 As shown, the battery fixing assembly involved in the embodiments of this application includes: screw 100 and fixing bracket 200.

[0025] Specifically, the screw 100 has a shank 110, which includes a threaded section 111; the fixing bracket 200 is provided with a connecting hole 210, and the fixing bracket 200 also has an anti-disengagement part, which at least partially protrudes from the wall of the connecting hole 210 in the radial direction, and the threaded section 111 passes through the connecting hole 210. The anti-disengagement part abuts against the threaded section 111 when the screw 100 is in the unscrewed state.

[0026] In the battery fixing assembly of this application, the fixing bracket 200 is used to establish a connection with the battery body. Since the threaded section 111 passes through the connecting hole 210, it can be screwed into the main unit of the device, thus detachably connecting the fixing bracket 200 to the main unit of the device, thereby completing a stable connection between the battery and the main unit of the device. When the battery needs to be removed, simply unscrew the threaded section 111 from the main unit of the device. During this process, because the anti-detachment part abuts against the threaded section 111 when the screw 100 is in the unscrewed state, the threaded section 111 will structurally interfere with the anti-detachment part after the screw 100 is unscrewed from the main unit of the device, keeping it within the range of the connecting hole 210. This design effectively reduces the possibility of the screw 100 accidentally falling off the fixing bracket 200 during disassembly, thereby significantly reducing the risk of the screw 100 falling into the main unit of the device.

[0027] Specifically, in some embodiments, the power device can be an electronic product such as a laptop, tablet, or mobile phone. The power device typically includes a host and a battery. The host is powered by an electrical connection between the battery and the host, so that the power device can operate normally. When the battery is electrically connected to the host, the battery can be fixed to the host of the power device by connecting the fixing bracket 200 to the host of the power device.

[0028] Reference Figure 1 as well as Figure 2 As shown, in some embodiments, the rod portion 110 further includes a guide section 112, which is connected to one end of the threaded section 111 along the axial direction of the threaded section 111 and is coaxially arranged with the threaded section 111. The anti-detachment portion is provided with an anti-detachment hole 220, which is coaxially arranged with and communicates with the connecting hole 210. The guide section 112 passes through the anti-detachment hole 220, and the threaded section 111 passes through the connecting hole 210. The diameter of the guide section 112 is D1, the diameter of the threaded section 111 is D2, and the diameter of the anti-detachment hole 220 is D3, satisfying: D1 < D3 < D2.

[0029] In this embodiment, the guide segment 112 is connected to one end of the threaded segment 111 along the axial direction of the threaded segment 111 and is coaxially arranged with the threaded segment 111. The guide segment 112 passes through the anti-loosening hole 220, thereby providing guidance for the assembly process between the screw 100 and the fixing bracket 200. Since the diameter D1 of the guide segment 112 and the diameter D3 of the anti-loosening hole 220 satisfy: D1 < D3, the guide segment 112 can move relative to the screw 100 in its axial direction within the anti-loosening hole 220, thereby allowing the screw 100 to be displaced relative to the fixing bracket 200, so as to realize the loosening operation of the screw 100. Meanwhile, since the diameter D1 of the guide section 112 and the diameter D2 of the threaded section 111 satisfy the condition: D1 < D2, when the screw 100 moves relative to the guide section 112, the threaded section 111 will cause structural interference with the edge of the anti-loosening hole 220, preventing it from entering the anti-loosening hole 220 and keeping it within the range of the connecting hole 210, thereby reducing the possibility that the screw 100 may accidentally fall off the fixing bracket 200 during disassembly.

[0030] Reference Figure 2 As shown, in some embodiments, the length of the threaded segment 111 along its axial direction is L1, and the length of the connecting hole 210 along its axial direction is L2, satisfying: L1 < L2.

[0031] In this embodiment, if L1 > L2, when the screw 100 undergoes axial displacement relative to the fixed bracket 200, the length of the connecting hole 210 will be insufficient to accommodate the entire threaded section 111. Consequently, the screw 100 will interfere with the edge of the anti-detachment hole 220 during the unscrewing process, further preventing the threaded section 111 from being unscrewed from the main unit of the electrical device, thus preventing the screw 100 from being disassembled. When L1 < L2, when the screw 100 undergoes axial displacement relative to the fixed bracket 200, the entire threaded section 111 can be accommodated within the connecting hole 210. Thus, the screw 100 will not interfere with the edge of the anti-detachment hole 220 during the unscrewing process, allowing the threaded section 111 to be unscrewed from the main unit of the electrical device, thereby enabling the disassembly of the battery from the main unit of the electrical device.

[0032] Continue to refer to Figure 2 As shown, in some embodiments, the diameter of the connecting hole 210 is D4, satisfying: D4 > D2.

[0033] In this embodiment, if D4 < D2, when the screw 100 undergoes axial displacement relative to the fixed bracket 200, the movement of the threaded segment 111 will be resisted by the hole wall of the connecting hole 210, thus increasing the difficulty of disassembling the screw 100. When D4 > D2, the threaded segment 111 can move smoothly within the connecting hole 210, thereby improving the convenience of disassembling the screw 100.

[0034] Reference Figure 2 As shown, in some embodiments, the anti-detachment part includes a first anti-detachment part 230, which is connected to the hole wall of the connecting hole 210 and extends circumferentially along the connecting hole 210, and protrudes from the hole wall of the connecting hole 210 in the radial direction. The anti-detachment hole 220 is formed on the first anti-detachment part 230.

[0035] In this embodiment, since the anti-loosening hole 220 is formed on the first anti-loosening part 230, when it is necessary to assemble the screw 100 with the fixing bracket 200, the screw 100 can be screwed into the first anti-loosening part 230, allowing it to pass through the anti-loosening hole 220 and the connecting hole 210 in sequence, thereby achieving a reliable fastening between the two. It is worth noting that since the first anti-loosening part 230 is connected to the hole wall of the connecting hole 210 and extends circumferentially along the connecting hole 210, and protrudes from the hole wall of the connecting hole 210 in the radial direction, when the screw 100 undergoes axial displacement relative to the fixing bracket 200, the threaded segment 111 will mechanically interfere with the first anti-loosening part 230 at various points along its circumference, thereby preventing the threaded segment 111 from entering the anti-loosening hole 220 area, ensuring that the screw 100 always remains within the effective constraint range of the connecting hole 210. This structural feature effectively reduces the occurrence of the screw 100 accidentally falling off the fixing bracket 200.

[0036] Continue to refer to Figure 2 As shown, in some embodiments, the screw 100 further has a head 120, and the threaded segment 111 and the head 120 are respectively connected to the two ends of the guide segment 112 along the axial direction of the guide segment 112. The head 120 is exposed outside the anti-loosening hole 220 and the connecting hole 210 and can abut against the fixing bracket 200. The first anti-loosening part 230 has a first guide surface 231. The first guide surface 231 is disposed at one end of the first anti-loosening part 230 along the axial direction of the anti-loosening hole 220 near the head 120 and at the edge of the anti-loosening hole 220. The first guide surface 231 is set at an angle to the radial direction of the anti-loosening hole 220 and is inclined in a direction away from the head 120.

[0037] In this embodiment, since the head 120 of the screw 100 is exposed outside the anti-loosening hole 220 and the connecting hole 210, and can abut against the fixing bracket 200, the screw 100 can be tightened and firmly fixed to the fixing bracket 200, thereby ensuring a reliable connection between the battery and the main unit of the electrical device. Furthermore, since the first guide surface 231 is disposed at the edge of the anti-loosening hole 220 and forms an inclined angle along the radial direction of the anti-loosening hole 220, extending away from the head 120, the first guide surface 231 guides the screw 100 during installation, allowing the screw 100 to enter the anti-loosening hole 220 and the corresponding connecting hole 210 more smoothly, thus improving the efficiency of screw 100 installation and its connection reliability.

[0038] Reference Figure 3 As shown, in some embodiments, the anti-detachment part includes a plurality of second anti-detachment parts 240, which are spaced apart on the wall of the connecting hole 210 along the circumferential direction. Each second anti-detachment part 240 protrudes from the wall of the connecting hole 210 in the radial direction. The plurality of second anti-detachment parts 240 surround to form an anti-detachment hole 220.

[0039] In this embodiment, a plurality of second anti-detachment portions 240 are arranged around the screw to define the anti-detachment hole 220. Therefore, when assembling the screw 100 with the fixing bracket 200, the screw 100 can be screwed into and pass through the gaps between the plurality of second anti-detachment portions 240, and then sequentially pass through the anti-detachment hole 220 and the connecting hole 210, thereby achieving a reliable fastening between the screw 100 and the fixing bracket 200. It should be noted that since each second anti-detachment portion 240 protrudes from the wall of the connecting hole 210 in the radial direction, when the screw 100 undergoes axial displacement relative to the fixing bracket 200, its threaded segment 111 will mechanically interfere with any one of the second anti-detachment portions 240, thereby preventing the threaded segment 111 from entering the anti-detachment hole 220 area. This ensures that the screw 100 is always within the effective constraint range of the connecting hole 210, effectively avoiding the risk of the screw 100 accidentally falling off the fixing bracket 200. Furthermore, since multiple second anti-detachment parts 240 are circumferentially spaced on the wall of the connecting hole 210, the contact area between the threaded section 111 of the screw 100 and the fixing bracket 200 is reduced, thereby further improving the smoothness and operational efficiency of the screw 100 screwing process.

[0040] Continue to refer to Figure 3As shown, in some embodiments, the wall of the connecting hole 210 is provided with a plurality of clearance grooves 250. The plurality of clearance grooves 250 are arranged at intervals along the circumference of the connecting hole 210. Each clearance groove 250 is connected to the connecting hole 210. Each second anti-detachment part 240 passes through a clearance groove 250 and moves radially relative to the clearance groove 250 along the connecting hole 210.

[0041] In this embodiment, when the screw 100 is assembled with the fixing bracket 200, the screw 100 applies a thrust to the second anti-detachment part 240 in the radial direction of the anti-detachment hole 220. Since each relief groove 250 is connected to the corresponding connecting hole 210, and each second anti-detachment part 240 passes through the corresponding relief groove 250 and can move relative to the relief groove 250 in the radial direction of the connecting hole 210, under the thrust applied by the screw 100, the second anti-detachment part 240 can be displaced relative to the relief groove 250 in the radial direction of the connecting hole 210, thereby reducing the interference caused by the second anti-detachment part 240 to the screw 100 installation process.

[0042] Continue to refer to Figure 3 As shown, in some embodiments, the fixed bracket 200 also has an elastic support portion 260, which is disposed in the clearance groove 250 and has an elastic potential energy in the radial direction of the connecting hole 210. The two ends of the elastic support portion 260 in the radial direction of the connecting hole 210 are respectively connected to the groove wall of the clearance groove 250 and the second anti-detachment portion 240.

[0043] In this embodiment, since the elastic support 260 has elastic potential energy in the radial direction of the connecting hole 210, and both ends of the elastic support 260 in the radial direction of the connecting hole 210 are connected to the groove wall of the relief groove 250 and the second anti-loosening part 240 respectively, when the screw 100 applies an axial thrust to the second anti-loosening part 240 during installation, the elastic support 260 will undergo compressive deformation under the displacement of the second anti-loosening part 240, thereby giving the elastic support 260 elastic potential energy to drive the second anti-loosening part 240 to move toward the central axis of the connecting hole 210. In this way, the elastic support 260 can provide continuous support to the second anti-loosening part 240, ensuring that the second anti-loosening part 240 is always at least partially located inside the connecting hole 210, thereby effectively realizing the anti-loosening function of the second anti-loosening part 240 for the screw 100.

[0044] Continue to refer to Figure 3 As shown, in some embodiments, the second anti-detachment part 240 has a second guide surface 241, which is disposed at one end of the second anti-detachment part 240 along the axial direction of the connecting hole 210 and close to the head 120, and is set at an angle to the radial direction along the connecting hole 210, and is inclined in a direction away from the head 120.

[0045] In this embodiment, since the second guide surface 241 is disposed axially toward the head 120 along the connecting hole 210 and at an angle to the radial direction along the connecting hole 210, and is inclined away from the head 120, the first guide surface 231 can guide the screw 100 during installation, thereby allowing the screw 100 to enter the anti-loosening hole 220 and the corresponding connecting hole 210 more smoothly. At the same time, when the screw 100 applies an axial thrust to the second anti-loosening part 240 during installation, the inclined structure of the second guide surface 241 can significantly reduce the resistance between the screw 100 and the second anti-loosening part 240, making the screw 100 more smoothly screwed in, thereby further reducing the installation difficulty of the screw 100.

[0046] Specifically, the second guide surface 241 is an arc-shaped guide surface, which has better guiding ability and the ability to reduce screwing resistance, so that the screw 100 can be screwed in more smoothly.

[0047] This application provides a battery, including: the battery fixing assembly described above.

[0048] In the battery of this application, since the aforementioned battery fixing component reduces the risk of the screw 100 falling into the main unit of the electrical device, the battery of this application has the advantage of being easy to install and remove.
