Therefore, they cannot be understood as limiting the present invention.

[0031] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art in the art of the present invention. The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention.

[0032] See Figure 1 、 Figure 2 and Figure 3 , the utility model discloses a quick-release shock-absorbing device.

[0033] A quick-release shock absorber device comprises a shock absorber body 1 and a fixing seat 2 for mounting the shock absorber body 1. The shock absorber body 1 is threadedly connected to the fixing seat 2, and a disassembly portion 3 is also threadedly connected to the shock absorber body 1.

[0034] The shock absorber body 1 is threadedly fixed to the fixing seat 2 along a first rotation direction, and the disassembly portion 3 is threadedly fixed to the shock absorber body 1 along a second rotation direction. The second rotation direction is opposite to the first rotation direction.

[0035] When the disassembly portion 3 is rotated in the second rotational direction, the disassembly portion 3 and the shock absorber body 1 are screwed together to form a fixed connection, and the disassembly portion 3 drives the shock absorber body 1 to rotate in the second rotational direction, so that the shock absorber body 1 is screwed out of the fixing seat 2. That is, when the disassembly portion 3 and the shock absorber body 1 are fixedly connected, the disassembly portion 3 is rotated in the second rotational direction, driving the shock absorber body 1 to rotate in the second rotational direction, so that the shock absorber body 1 is screwed out of the fixing seat 2, and the shock absorber body 1 can be removed from the fixing seat 2.

[0036] Based on the above technical solution, the shock absorber body 1 is threadedly fixed to the fixing seat 2 along a first rotation direction, and the second rotation direction is opposite to the first rotation direction. The second rotation direction is the loosening direction of the shock absorber body 1 from the fixing seat 2. When the shock absorber body 1 rotates along the second rotation direction, the shock absorber body 1 can be unscrewed from the fixing seat 2.

[0037] Based on the above technical solution, when the shock absorber main body 1 needs to be removed from the fixing seat 2, the shock absorber main body 1 can be driven to rotate simply by rotating the disassembly portion 3, and the rotation is in the second rotation direction, thereby achieving the removal of the shock absorber main body 1 from the fixing seat 2. After the disassembly portion 3 is screwed into the shock absorber main body 1 along the second rotation direction, or when the disassembly portion 3 and the shock absorber main body 1 are in a tightened state, the disassembly portion 3 is then rotated along the second rotation direction. There is basically no relative rotation between the disassembly portion 3 and the shock absorber main body 1. At this time, the disassembly portion 3 will drive the shock absorber main body 1 to rotate along with the disassembly portion 3 in the second rotation direction, and the shock absorber main body 1 can be removed from the fixing seat 2.

[0038] Based on the above technical solution, the disassembly portion 3 is used to remove the shock absorber body 1 from the fixing base 2, making the disassembly operation simple and convenient. In addition, during the process of removing the shock absorber body 1 from the fixing base 2, it is no longer necessary to clamp the shock absorber body 1 with an external disassembly tool, such as a caliper, to clamp the shock absorber body 1. This effectively prevents the shock absorber body 1 from being worn and damaged, thereby reducing maintenance costs and usage costs.

[0039] In this technical solution, the shock absorber body 1 is inserted into the fixing seat 2, and the shock absorber body 1 is provided with a first external thread 12 that is threadedly connected to the fixing seat 2. The fixing seat 2 is provided with a first internal thread 21 that adapts to the first external thread 12. The first external thread 12 is threadedly connected to the first internal thread 21. The shock absorber body 1 is screwed into the fixing seat 2 along a first rotation direction.

[0040] The first external thread 12 is provided on the shock absorber body 1, and the first internal thread 21 is provided on the fixing base 2, so as to facilitate the threaded connection between the shock absorber body 1 and the fixing base 2. In addition, the first external thread 12 is provided on the shock absorber body 1, which does not affect the installation and use of the shock absorber components inside the shock absorber body 1, and also facilitates thread processing.

[0041] The fixing seat 2 is used for fixing and installing the shock-absorbing body 1 . Generally, the fixing seat 2 is relatively short to facilitate the processing of the internal thread.

[0042] like Figure 1 and Figure 2 As shown, in Figure 1 and Figure 2 In the illustrated state, the shock absorber body 1 is screwed into the fixing base 2 from the upper end of the fixing base 2. Assuming that the first external thread 12 and the first internal thread 21 are both right-handed, the first rotation direction should be clockwise. The counterclockwise direction is the second rotation direction, that is, the shock absorber body 1 is screwed into the fixing base 2 in a clockwise direction. When the shock absorber body 1 needs to be removed from the fixing base 2, the shock absorber body 1 should be rotated counterclockwise. Therefore, by rotating the disassembly portion 3 in a counterclockwise direction, the shock absorber body 1 is driven to rotate counterclockwise, driving the shock absorber body 1 to be unscrewed from the fixing base 2.

[0043] In this technical solution, the disassembly portion 3 is provided on the shock absorber body 1, and the shock absorber body 1 is provided with a second internal thread 13. The disassembly portion 3 is provided with a second external thread 31, and the second external thread 31 is threadedly connected to the second internal thread 13. The second external thread 31 and the first external thread 12 have the same rotation direction, and the movement direction of the disassembly portion 3 when screwed into the shock absorber body 1 is opposite to the movement direction when the shock absorber body 1 is screwed into the fixing base 2.

[0044] The disassembly portion 3 is screwed into the shock-absorbing body 1 along a second rotation direction, which is opposite to the first rotation direction.

[0045] After the disassembly portion 3 is screwed into the shock absorber body 1 and the disassembly portion 3 and the shock absorber body 1 are tightened, and after the disassembly portion 3 and the shock absorber body 1 are in a fixed state, the disassembly portion 3 is rotated along the second rotation direction to drive the shock absorber body 1 to be rotated out of the fixing seat 2 along the second rotation direction.

[0046] Based on the above scheme, the second external thread 31 has the same rotation direction as the first external thread 12, and the movement direction of the disassembly part 3 when screwing into the shock absorber main body 1 is opposite to the movement direction when the shock absorber main body 1 is screwed into the fixing seat 2. In this way, it can be ensured that when the second external thread 31 has the same rotation direction as the first external thread 12, the disassembly part 3 can drive the shock absorber main body 1 to be screwed out of the fixing seat 2.

[0047] Based on the above technical solution, the disassembly portion 3 is passed through or set in the shock absorber body 1, or is set at one end of the shock absorber body 1, and the central axis of the second rotation direction coincides with the central axis of the first rotation direction.

[0048] like Figure 1 and Figure 2 As shown, in Figure 1 and Figure 2 From the perspective of the shown state, when the first external thread 12 is a right-handed positive thread and the first rotation direction is clockwise, the second internal thread 13 and the second external thread 31 are both right-handed positive threads, and the counterclockwise direction is the second rotation direction. Figure 2 In the figure, the disassembly part 3 is screwed into the shock absorber main body 1 from the bottom of the shock absorber main body 1, so the movement direction of the disassembly part 3 screwed into the shock absorber main body 1 is opposite to the movement direction of the shock absorber main body 1 screwed into the fixing seat 2. At this time, the disassembly part 3 is screwed into the shock absorber main body 1 in a counterclockwise direction to achieve threaded connection with the shock absorber main body 1.

[0049] After the disassembly part 3 rotates along the second rotation direction and is fixedly connected to the shock absorber main body 1, the disassembly part 3 continues to rotate along the second rotation direction. There is basically no mutual rotation between the disassembly part 3 and the shock absorber main body 1, that is, the main parts move relative to each other. At this time, the shock absorber main body 1 is driven by the disassembly part 3 to rotate synchronously. That is, the shock absorber main body 1 rotates along the second rotation direction, which is opposite to the direction in which the shock absorber main body 1 is screwed into the fixing seat 2. Therefore, the shock absorber main body 1 can be screwed out from the fixing seat 2, so that the shock absorber main body 1 can be disassembled from the fixing seat 2.

[0050] Of course, in other embodiments, if the direction of movement of the disassembly portion 3 when screwed into the shock absorber body 1 is the same as the direction of movement of the shock absorber body 1 when screwed into the fixing base 2, then the rotation direction of the external threads on the disassembly portion 3 and the external threads on the shock absorber body 1 should be opposite. In this case, after the disassembly portion 3 is threadedly connected to the shock absorber body 1, continuing to rotate the disassembly portion 3 in the screwing direction will drive the shock absorber body 1 to rotate in the loosening direction, and the shock absorber body 1 can also be unscrewed from the fixing base 2.

[0051] In some embodiments, the disassembly portion 3 is sleeved on the shock absorber body 1. The shock absorber body 1 is provided with a third external thread, and the disassembly portion 3 is provided with a third internal thread, the third internal thread being threadedly connected to the third external thread, and the third external thread and the first external thread 12 have the same rotation direction, and the movement direction of the disassembly portion 3 when screwed into the shock absorber body 1 is opposite to the movement direction when the shock absorber body 1 is screwed into the fixing base 2.

[0052] The disassembly portion 3 is screwed into the shock absorber body 1 along a second rotation direction, and the second rotation direction is opposite to the first rotation direction;

[0053] After the disassembly portion 3 is screwed onto the shock absorber body 1 , the disassembly portion 3 is continued to be rotated to drive the shock absorber body 1 to be rotated out of the fixing seat 2 along the first rotation direction.

[0054] In this embodiment, the connection method between the disassembly part 3 and the shock absorber body 1, and the process of the disassembly part 3 driving the shock absorber body 1 to be disassembled from the fixing seat 2 are the same as those in the aforementioned embodiment in which the disassembly part 3 is passed through the shock absorber body 1, and will not be repeated here.

[0055] In this technical solution, the shock absorber body 1 includes an outer oil cylinder 11, and the first external thread 12 is arranged on the outer peripheral surface of the outer oil cylinder 11, which facilitates the processing of the first external thread 12 and does not affect or interfere with the internal structure of the outer oil cylinder 11.

[0056] In this technical solution, the fixing seat 2 includes a through-hole 22, and at least one end of the outer oil cylinder 11 passes through the through-hole 22. A blocking seat is provided at one end of the outer oil cylinder 11, and a rotating operating portion 32 is provided on the blocking seat. The blocking seat forms the disassembly portion 3. The through-hole 22 is provided to facilitate the connection between the outer oil cylinder 11 and the fixing seat 2. Figure 2 In the state shown, the disassembly portion 3 is arranged at the bottom of the outer oil cylinder 11. When the disassembly portion 3 is screwed into the shock absorber body 1, the disassembly portion 3 should move upward. At this time, the second external thread 31 on the disassembly portion 3 and the first external thread 12 on the outer oil cylinder 11 have the same rotation direction, and the movement direction of the disassembly portion 3 when screwed into the shock absorber body 1 is opposite to the movement direction when the shock absorber body 1 is screwed into the fixing seat 2.

[0057] Based on the above solution, the end of the outer oil cylinder 11 away from the blocking seat passes through the through-hole 22 and is provided with the piston rod 14. The through-hole 22 is provided on the fixing seat 2 to facilitate the passage of the two ends of the outer oil cylinder 11, facilitate the installation of the piston rod 14 and the disassembly part 3, facilitate the connection of the piston rod 14 with other structures on the balance vehicle, and facilitate the operation of the disassembly part 3 when the shock absorber body 1 is removed from the fixing seat 2.

[0058] In addition, in the present technical solution, the sealing seat of the outer oil cylinder 11 is used as the disassembly portion 3 , which simplifies the structure, reduces costs, and reduces the volume of the shock-absorbing body 1 .

[0059] In this technical solution, to facilitate the rotation of the disassembly portion 3, a rotational operating portion 32 is provided on the blocking seat. The rotational operating portion 32 comprises at least one of an internal hexagonal hole, an external hexagonal prism, an external square prism, a cross slot, and a slotted slot. Disassembly can be completed using only a wrench or screwdriver, making it simple and convenient, requiring no specialized tools, and offering strong adaptability.

[0060] The present invention also provides a self-balancing vehicle equipped with the aforementioned quick-release shock-absorbing device. The self-balancing vehicle also includes an in-wheel motor and an upper body disposed above the wheel. The upper body is fixedly connected to the piston rod 14 of the quick-release shock-absorbing device, and a fixing base 2 is mounted on the in-wheel motor. Several mounting holes 23 are provided on the fixing base 2 to facilitate the removable fixing of the fixing base 2 and the in-wheel motor, making the self-balancing vehicle easy to maintain and low in cost.

[0061] The technical means disclosed in the present invention are not limited to those disclosed in the above-mentioned embodiments, but also include technical solutions composed of any combination of the above-mentioned technical features. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principles of the present invention, and such improvements and modifications are also considered to be within the scope of protection of the present invention.
