[0034] See also Figure 1 and Figure 2 The utility model provides a battery decoration structure, which is installed on a battery body 1. The battery body 1 is provided with a screw 11, including a decorative cover 2 and a self-locking component 3. The decorative cover 2 is detachably connected to the battery body 1 and is used to cover the end of the screw 11 facing the outside; the self-locking component 3 is detachably connected to the battery body 1, and the decorative cover 2 is provided with a mounting hole 21, which is used for the self-locking component 3 to pass through the mounting hole 21 and limit the position of the decorative cover 2 when the decorative cover 2 is installed to the battery body 1.

[0035] Among them, the shape of the decorative cover 2 is adapted to the shape of the outer shell of the battery body 1, and the installation part 4 is provided with an installation groove 41 for placing the battery body 1. When the self-locking component 3 fixes the decorative cover 2 on the battery body 1, the battery body 1 is placed in the installation groove 41 to complete the installation of the battery body 1.

[0036] It can be understood that the number of decorative covers 2 and self-locking components 3 can be the same or different. The number of decorative covers 2 can be flexibly adjusted according to the number of screws 11 on the battery body 1. Multiple self-locking components 3 can be provided on one decorative cover 2. In this embodiment, one decorative cover 2 is connected to two self-locking components 3, and the two self-locking components 3 are respectively located on both sides of the decorative cover 2, and the length direction of the self-locking component 3 is perpendicular to the length direction of the screw 11.

[0037] In this way, the self-locking component 3 is installed on the battery body 1, and the decorative cover 2 is sleeved on the battery body 1, so that the self-locking component 3 limits the decorative cover 2 and can cover the exposed screws 11, thereby improving the aesthetics and safety. Under the protection of the decorative cover 2 and the self-locking component 3, external liquids are not easy to enter the battery body 1, thereby improving the waterproof performance of the battery body 1.

[0038] See also Figure 1 and Figure 2 In some embodiments, the self-locking component 3 includes an elastic member 31, a rotor 32, a push rod 33 and a button 35. One end of the elastic member 31 can be selectively abutted against the battery body 1, and the other end can be selectively abutted against the rotor 32. One end of the push rod 33 can be selectively rotatably connected to the rotor 32, and the other end can be detachably connected to the button 35, so that the button 35 drives the push rod 33 and the rotor 32 to move.

[0039] In this embodiment, the elastic member 31 is a compression spring, and two ends of the compression spring are respectively in contact with the battery body 1 and the rotor 32 . The compression spring, the rotor 32 , and the push rod 33 are coaxially arranged.

[0040] It is understandable that the elastic member 31 may also be other elastic structures, such as a spring sheet, a wave spring, etc. The specific structure of the elastic member 31 can be flexibly adjusted according to the actual design, and will not be listed in detail here.

[0041] It should be noted that when the decorative cover 2 needs to be installed, the elastic member 31, the rotor 32, and the top rod 33 are installed on the battery body 1 in sequence, and the button 35 is installed to the end of the top rod 33 away from the rotor 32. The elastic member 31 is at a natural length when not under pressure. When installing the decorative cover 2, the button 35 is pressed to make the button 35 push the rotor 32 and the top rod 33 to move in a direction close to the battery body 1. The elastic member 31 is compressed after being subjected to the pressure of the rotor 32, and the decorative cover 2 is installed on the battery body 1. The elastic member 31 releases the elastic force and pushes the rotor 32 and the top rod 33 to move in a direction away from the battery body 1, so that the button 35 is stuck in the installation hole 21, thereby limiting the decorative cover 2, and at this time, the outer wall of the button 35 is flush with the outer wall of the decorative cover 2; when the decorative cover 2 needs to be removed, the button 35 is pushed in a direction close to the battery body 1 to release the limit of the decorative cover 2 by the button 35, and then it can be removed.

[0042] In this way, by limiting the mounting hole 21 through the button 35, the decorative cover 2 can be stably installed on the battery body 1 and the exposed screws 11 can be protected; the decorative cover 2 can be quickly disassembled and assembled by pressing the button 35 set on the outside of the decorative cover 2, and the design that the outer wall of the button 35 is flush with the outer wall of the decorative cover 2 is more aesthetically pleasing and integrated.

[0043] See also Figure 3 and Figure 4 In some embodiments, an abutment block 321 is provided at one end of the rotor 32 facing the push rod 33, and a top tooth 331 is provided at one end of the push rod 33 facing the rotor 32. When the top tooth 331 moves toward the abutment block 321, the abutment block 321 drives the rotor 32 to rotate.

[0044] Among them, the rotor 32 is a cylindrical structure, the abutment block 321 is inclined toward one end of the push rod 33, and there are multiple abutment blocks 321, which are evenly arranged around the outer wall of the rotor 32; the top tooth 331 is a wedge-shaped structure, with its tip facing the inclined surface of the abutment block 321, and the end away from the tip is fixedly connected to the push rod 33, and there are multiple top teeth 331, which are evenly arranged around the outer wall of the top block.

[0045] In this embodiment, there are four abutment blocks 321 and eight top teeth 331. When the top teeth 331 abut against the inclined surface of the abutment block 321 and move toward the direction close to the battery body 1, the abutment block 321 drives the rotor 32 to rotate until the top teeth 331 are located between the two abutment blocks 321.

[0046] See also Figure 4 and Figure 5In some embodiments, the self-locking component 3 also includes a sleeve 34, the rotor 32 is located inside the sleeve 34 and is slidably connected to the sleeve 34, the push rod 33 extends out of the sleeve 34 toward one end of the key 35 and is slidably connected to the sleeve 34, and a plurality of groups of protrusion groups 342 are arranged on the inner wall of the end of the sleeve 34 facing the key 35, each group of protrusion groups 342 includes a first protrusion 3421 and a second protrusion 3422, the first protrusion 3421 and the second protrusion 3422 of the same group are fixedly connected, and the plurality of groups of protrusion groups 342 are arranged circumferentially along the inner wall of the sleeve 34.

[0047] In this embodiment, the sleeve 34 is detachably connected to the battery body 1, and the sleeve 34 is provided with a sliding cavity 341 for sliding of the elastic member 31, the rotor 32, and the push rod 33. The first protrusion 3421 is a rod-shaped structure whose shape is adapted to the abutment block 321. The length of the second protrusion 3422 is smaller than the length of the first protrusion 3421, and is used to prevent the rotor 32 from continuing to move when the rotor 32 rotates to abut against the second protrusion 3422. There are 4 groups of protrusion groups 342, and the 4 groups of protrusion groups 342 are evenly arranged along the circumference of the inner wall of the sleeve 34.

[0048] It is understandable that the number of the protrusion groups 342 can be adjusted according to the number of the abutment blocks 321 and the number of the top teeth 331 , which will not be listed in detail here.

[0049] See also Figure 4 and Figure 5 Further, a first groove 343 is formed between the first protrusion 3421 in one group and the second protrusion 3422 in the adjacent group, and a second groove 344 is formed between the first protrusion 3421 and the second protrusion 3422 in the same group. The length of the first groove 343 is greater than the length of the second groove 344, so that when the push rod 33 drives the rotor 32 to rotate, the abutment block 321 can be selectively inserted into the first groove 343 or abut with the protrusion group 342, and the push rod 33 can selectively slide in the first groove 343 or the second groove 344. The widths of the first groove 343 and the second groove 344 are the same.

[0050] It should be noted that the top tooth 331 and the abutment block 321 both slide in the first groove 343 or the second groove 344. Each time the top rod 33 slides, the abutment block 321 rotates once, so that the abutment block 321 alternately extends into the first groove 343 or abuts against the second protrusion 3422. When the abutment block 321 extends into the first groove 343, the side of the button 35 close to the outside is flush with the outer surface of the battery body 1, and the decorative shell is in a removable state at this time; when the button 35 is pressed again to make the top rod 33 push the rotor 32 to rotate and the abutment block 321 abuts against the second protrusion 3422, the side of the button 35 close to the outside passes through the mounting hole 21 and is flush with the decorative shell. At this time, the decorative shell is limited by the button 35, and the decorative shell is in a state of being installed on the battery body 1.

[0051] In this way, by pressing the button 35 to make the push rod 33 drive the rotor 32 to rotate, the operation is simple and convenient, the decorative cover 2 can be quickly disassembled and assembled, so that it can protect and cover the screws 11 and has a high aesthetics.

[0052] See also Figure 4 and Figure 5 In some embodiments, the end surface slope of the first protrusion 3421 toward the abutment block 321 is the same as the end surface slope of the abutment block 321 toward the first protrusion 3421, and the end surface slope of the second protrusion 3422 toward the abutment block 321 is the same as the end surface slope of the abutment block 321 toward the second protrusion 3422.

[0053] In this way, the end face inclination of the first protrusion 3421 toward the abutment block 321 and the end face inclination of the second protrusion 3422 toward the abutment block 321 are the same as the end face inclination of the abutment block 321 toward the top rod 33, which can reduce the gap between the abutment block 321 and the protrusion group 342, increase the sealing between the sliding sleeve 34, the rotor 32 and the top rod 33, and improve the waterproof performance.

[0054] See also Figure 4 and Figure 5 In some embodiments, the width of the top tooth 331 is the same as the width of the first groove 343 , and the width of the top tooth 331 is the same as the width of the second groove 344 .

[0055] It can be understood that the width of the top tooth 331, the width of the first groove 343, and the width of the second groove 344 may be unequal to each other, as long as the top tooth 331 can slide in the first groove 343 or the second groove 344; in this embodiment, the width of the top tooth 331, the width of the abutment block 321, the width of the first groove 343, and the width of the second groove 344 are all equal.

[0056] In this way, the top tooth 331 can stably slide in the first groove 343 or the second groove 344, and is not prone to deviation in other directions, which can improve the efficiency of disassembly and assembly of the decorative cover 2 and make the connection between the decorative cover 2 and the battery body 1 more stable; the width of the top tooth 331 is equal to the width of the first groove 343 and the width of the second groove 344, which can also further improve the waterproof performance and prevent liquid from entering the battery body 1 through the sliding sleeve 34.

[0057] See also Figure 4 In some embodiments, the rotor 32 is provided with a limit block 322 , and the limit block 322 is fixedly connected to the abutment block 321 to limit the moving distance of the rotor 32 in the sleeve 34 .

[0058] Among them, the limit block 322 is fixedly connected to the end of the abutment block 321 away from the push rod 33, the diameter of the limit block 322 is larger than the diameter of the rotor 32, the sliding cavity 341 is a stepped groove, and the maximum inner diameter of the sliding cavity 341 is adapted to the diameter of the limit block 322, so that after the rotor 32 slides a certain distance in the sleeve 34, the limit block 322 abuts against the inner wall of the sliding cavity 341 to limit the further sliding of the rotor 32.

[0059] In this way, by setting the step position in the sliding cavity 341 , the moving distance of the rotor 32 can be adjusted, thereby adjusting the moving distance of the ejector rod 33 and the button 35 to match the decorative cover 2 of a specific thickness.

[0060] See also Figure 3 In some embodiments, a limiting groove 323 is correspondingly formed at one end of the rotor 32 facing the elastic member 31 , and one end of the elastic member 31 extends into the limiting groove 323 and abuts against the end surface of the limiting groove 323 .

[0061] In this embodiment, the limiting groove 323 is a stepped groove, the diameter of one end of the limiting groove 323 facing the elastic member 31 is larger than the diameter of the other end away from the elastic member 31 , and the maximum diameter of the limiting groove 323 matches the diameter of the elastic member 31 .

[0062] In this way, one end of the elastic member 31 extends into the limiting groove 323 and can be compressed or reset more stably, avoiding the displacement of the connection between the elastic member 31 and the rotor 32 and affecting the sliding of the rotor 32, thereby affecting the ejection or retraction of the button 35.

[0063] See also Figure 2 In some embodiments, a connection block 351 is provided at one end of the button 35 facing the top rod 33, and a connection groove 332 is provided at one end of the top rod 33 facing the button 35 corresponding to the connection block 351, so as to enable the button 35 to be plugged into the top rod 33. Furthermore, the shape of the connection groove 332 is adapted to the shape of the connection block 351.

[0064] See also Figure 2 and Figure 6 In some embodiments, the battery body 1 is provided with a mounting tube 12, the number of which corresponds to the number of the self-locking components 3, so that the self-locking components 3 extend into the mounting tube 12 and limit the decorative cover 2. Further, when the self-locking components 3 extend into the mounting tube 12, the self-locking components 3 are coaxial with the mounting tube 12.

[0065] In this way, the mounting tube 12 can provide space for the installation of the self-locking component 3, so that it can be stably connected to the battery body 1, which is convenient for limiting the decorative cover 2; and installing the self-locking component 3 into the mounting tube 12 can improve the disassembly and assembly efficiency and achieve the effect of quickly disassembling and assembling the decorative cover 2; the mounting tube 12 can further block the liquid from easily entering the interior of the battery body 1, thereby improving the waterproof performance.

[0066] See also Figure 1 The utility model also provides a battery, including a battery body 1 and a battery decoration structure, wherein screws 11 are connected to both ends of the battery body 1, and the battery decoration structure and both ends of the battery body 1 are detachably connected through a self-locking component 3 of a battery decoration cover.
