Description

Technical Field

[0001] This utility model relates to the field of shock absorber technology, specifically to an installation structure for a shock absorber. Background Technology

[0002] Shock absorbers, also known as vibration dampers, are mechanical components used to absorb and reduce vibrations. They are widely used in various machinery, vehicles, construction, and other fields to help reduce the adverse effects of impacts or vibrations, protect equipment and personnel, and extend service life.

[0003] Currently, shock absorbers are widely used in electric bicycles and motorcycles. The conventional installation method is to connect the top to the frame bracket and mount the bottom to the vehicle's swingarm. However, most existing shock absorbers use a fixed circular connection structure for the bottom mounting port. This design has obvious limitations. Since the mounting interfaces of swingarms of different models vary in size and diameter, the fixed circular mounting port often cannot be directly adapted and requires additional processing of adapters for installation. More importantly, the mounting port and the shock absorber body are mostly integrated or non-removable, making it impossible to flexibly change the mounting interface according to the actual specifications of the swingarm lugs. This not only increases the complexity of installation but also makes it difficult for a single shock absorber to be adapted to multiple vehicle models, greatly limiting its applicability and versatility. Utility Model Content

[0004] The purpose of this invention is to provide an installation structure for a shock absorber to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a shock absorber mounting structure, including a shock absorber body, and further comprising:

[0006] A first mounting interface rotates on the top of the shock absorber body via a bearing, and a positioning cylinder is located at the bottom of the shock absorber body. The bottom of the positioning cylinder is provided with a second mounting interface. The inner cavity of the positioning cylinder is provided with a quick-release component for easy replacement of the second mounting interface. The quick-release component includes two locking plates, both of which are located in the inner cavity of the positioning cylinder.

[0007] Preferably, the surface of the card plate is engaged with a card cone, and the bottom of the card cone is fixedly connected to the second mounting interface.

[0008] Preferably, a threaded rod is rotatably connected to one side of the card plate via a bearing, and a threaded sleeve is threadedly connected to the surface of the threaded rod, with the surface of the threaded sleeve being fixedly connected to the inner wall of the positioning cylinder.

[0009] Preferably, a turntable is fixedly connected to one side of the threaded rod, and the surface of the turntable is provided with multiple anti-slip teeth.

[0010] Preferably, both ends of the card plate are fixedly connected to sliding sleeves, and the inner cavity of the sliding sleeve is slidably connected to a sliding rod, with both sides of the sliding rod being fixedly connected to the inner wall of the positioning cylinder.

[0011] Preferably, a spring is fixedly connected to one side of the sliding sleeve, the inner cavity of the spring is sleeved on the surface of the sliding rod, and one side of the spring is fixedly connected to one end of the sliding rod.

[0012] Preferably, a rotating rod is fixedly connected to the top of the positioning cylinder, and the top of the rotating rod is rotatably connected to the bottom of the shock absorber body through a bearing.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] This invention utilizes a quick-release mechanism. Rotating the turntable causes the connected threaded rod to rotate synchronously within the threaded sleeve's inner cavity. This rotation moves the two side clamping plates in opposite directions, gradually disengaging them from the clamping cone. Once the clamping plates are completely disengaged from the cone's surface, the cone is unlocked. Pulling down on the second mounting interface then causes the top cone to simultaneously disengage from the positioning cylinder's inner cavity, allowing for easy disassembly. The interface can then be replaced with one compatible with the flat fork's lifting lugs. This effectively solves the limitation of traditional fixed interfaces being incompatible with different flat forks, significantly improving the shock absorber's versatility and installation flexibility.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figure 1 - Figure 4 As shown, a shock absorber mounting structure includes a shock absorber body 1, and further includes:

[0022] The first mounting interface 2, which rotates on the top of the shock absorber body 1 via a bearing, is located at the bottom of the shock absorber body 1. The bottom of the positioning cylinder 3 is provided with a second mounting interface 4. The inner cavity of the positioning cylinder 3 is provided with a quick-release part 5 for easy replacement of the second mounting interface 4. The quick-release part 5 includes two locking plates 501, both of which are located in the inner cavity of the positioning cylinder 3.

[0023] A snap cone 502 is engaged with the surface of the clamping plate 501. The bottom of the snap cone 502 is fixedly connected to the second mounting interface 4. A threaded rod 503 is rotatably connected to one side of the clamping plate 501 via a bearing. A threaded sleeve 504 is threadedly connected to the surface of the threaded rod 503, and the surface of the threaded sleeve 504 is fixedly connected to the inner wall of the positioning cylinder 3. A turntable 505 is fixedly connected to one side of the threaded rod 503, and the surface of the turntable 505 is provided with multiple anti-slip teeth. Sliding sleeves 506 are fixedly connected to both ends of the clamping plate 501. A sliding rod 507 is slidably connected to the inner cavity of the sliding sleeve 506, and both sides of the sliding rod 507 are fixedly connected to the inner wall of the positioning cylinder 3. A spring 508 is fixedly connected to one side of the sliding sleeve 506. The inner cavity of the spring 508 is sleeved on the surface of the sliding rod 507, and one side of the spring 508 is fixedly connected to one end of the sliding rod 507. A threaded rod 508 is fixedly connected to the top of the positioning cylinder 3. The rotating rod 6 is rotatably connected to the bottom of the shock absorber body 1 via a bearing. When it is necessary to replace it with an interface that is more compatible with the flat fork lug, first rotate the turntable 505. The turntable 505 drives the threaded rod 503 to rotate synchronously in the inner cavity of the threaded sleeve 504. When the threaded rod 503 rotates, it drives the clamping plate 501 to move laterally. At the same time, it drives the sliding sleeves 506 at both ends of the clamping plate 501 to slide smoothly along the surface of the sliding rod 507. At this time, the sliding sleeve 506 will squeeze the spring 508 to gradually retract and store force. When the clamping plate 501 is completely separated from the surface of the clamping cone 502, the clamping cone 502 is released from the locked state. At this time, pull down the second installation interface 4. The interface will drive the top clamping cone 502 to simultaneously separate from the inner cavity of the positioning cylinder 3, completing the disassembly of the old interface. This effectively solves the limitation that the traditional fixed interface cannot be adapted to different flat forks, and greatly improves the versatility and installation flexibility of the shock absorber.

[0024] Working principle: First, rotate the turntable 505. The turntable 505 drives the threaded rod 503 to rotate synchronously in the inner cavity of the threaded sleeve 504. When the threaded rod 503 rotates, it drives the clamping plate 501 to move laterally. At the same time, it drives the sliding sleeves 506 at both ends of the clamping plate 501 to slide smoothly along the surface of the sliding rod 507. At this time, the sliding sleeves 506 will compress the spring 508 to gradually retract and store force. When the clamping plate 501 is completely separated from the surface of the clamping cone 502, the clamping cone 502 is released from the locked state. At this time, pull down the second installation interface 4. The interface will drive the top clamping cone 502 to simultaneously disengage from the inner cavity of the positioning cylinder 3, completing the disassembly of the old interface and replacing it with an interface adapted to the flat fork lifting lug. At this time, align the top clamping cone 502 of the new interface with the inner cavity of the positioning cylinder 3 and insert it. During the insertion process, the inclined surface of the clamping cone 502 will squeeze the clamping plates 501 on both sides to move outward. At the same time, it drives the sliding sleeves 506 on the clamping plate 501 to slide synchronously along the sliding rod 507. At this time, the spring 508 is compressed and stores force. When the clasp 502 is inserted into the preset position, its surface groove is precisely aligned and engaged with the plate 501. The spring 508 naturally extends, pushing the plate 501 to reset and embed into the groove, forming a preliminary engagement and fixation. Then, the turntable 505 is rotated, driving the threaded rod 503 to rotate in the inner cavity of the threaded sleeve 504. The threaded rod 503 drives the two side plates 501 to move further towards the center, firmly clamping the clasp 502 and completing the mechanical locking of the second mounting interface 4. After the interface is fixed, the first mounting interface 2 of the shock absorber body 1 is first fixed to the preset position on the frame with bolts. Then, the rotating rod 6 is rotated through the bearing, driving the positioning cylinder 3 and the second mounting interface 4 to finely adjust the angle to match the mounting angle of the flat fork hanger. After the angle is determined, the second mounting interface 4 is fastened to the flat fork hanger with bolts, thus effectively adapting to flat fork hangers of different specifications and angles, completely solving the adaptation limitations of traditional fixed interfaces, and realizing the rapid installation and multi-scenario compatibility of the shock absorber.
