Description

Technical Field

[0001] This utility model relates to the field of motorcycle protective cover technology, and in particular to a motorcycle chain protective cover structure with an internal buffer layer. Background Technology

[0002] The motorcycle chain is a key component of the motorcycle drive system, and its stability and lifespan directly affect riding safety and performance. However, because motorcycle chains operate under high-friction conditions for extended periods, the chain and surrounding components are susceptible to external impacts, wear, and damage. To improve motorcycle safety, comfort, and chain durability, protective covers are needed for motorcycle chains.

[0003] Currently, most motorcycle chain guards are protective shells made of metal that enclose the chain. While this design provides basic protection, friction inevitably occurs between the chain and the guard during motorcycle riding, especially under bumpy or vibrating conditions. This not only accelerates wear on both the chain and the guard but can also lead to overheating, increased noise, and aggravated vibrations, significantly impacting riding comfort and the overall performance of the motorcycle. Utility Model Content

[0004] Therefore, it is necessary to provide a motorcycle chain guard structure with a built-in buffer layer to address the problem of significant wear caused by the chain contacting the guard when the vehicle is subjected to bumps.

[0005] A motorcycle chain guard structure with a built-in buffer layer includes: a housing, the surface of which is provided with two mounting holes;

[0006] A buffer mechanism, comprising a buffer shell disposed at the top inner side of the housing, a buffer plate disposed inside the buffer shell, and multiple sets of buffer components disposed between the buffer plate and the inner top wall of the buffer shell.

[0007] In one embodiment, a positioning plate is fixedly connected to the lower surface of the buffer plate, and multiple rotating rollers are rotatably connected to the lower surface of the positioning plate.

[0008] In one embodiment, the buffer assembly includes a cylinder fixedly connected to the inner top wall of the buffer housing, a piston plate slidably connected inside the cylinder, and a spring fixedly connected between the piston plate and the inner top wall of the cylinder.

[0009] In one embodiment, a piston rod is fixedly connected to the lower surface of the piston plate. The piston rod is a hollow rod, and the bottom end of the piston rod extends through the cylinder body.

[0010] In one embodiment, a connecting block is slidably connected to the inner wall of the piston rod, and the bottom end of the connecting block is disc-shaped.

[0011] In one embodiment, a limiting disc is fixedly connected to the surface of the piston rod, and an airbag is provided between the limiting disc and the bottom end of the connecting block. The airbag is sleeved on the surface of the connecting block, and the lower surface of the connecting block is fixedly connected to a buffer plate.

[0012] In one embodiment, two bolts are fixedly connected to the upper surface of the buffer shell, and two corresponding positioning holes are opened at the top of the shell.

[0013] In one embodiment, the surface of the housing has multiple through holes, which are evenly distributed in a straight line.

[0014] Beneficial effects

[0015] 1. By incorporating a buffer mechanism to create a buffer layer between the protective shell and the chain, direct contact between the chain and the protective shell can be effectively reduced, thereby reducing friction-induced wear on the chain and protective shell. This also reduces chain overheating and noise problems caused by excessive friction, extending the chain's lifespan. Furthermore, the buffer layer can absorb vibrations generated by the chain, reducing the feeling of vibration during vehicle operation.

[0016] 2. By incorporating a buffer component, the device's buffer mechanism achieves a dual damping effect, automatically adjusting to the magnitude of bumps experienced by the vehicle to provide a more suitable damping response. The first buffer layer absorbs minor vibrations, while the second layer provides stronger shock absorption during larger bumps, effectively mitigating the impact of vibrations on the chain and protective shell, thus improving the practicality of the protective shell.

[0029] The following is combined with Figures 1-4 This invention describes the structure of a motorcycle chain guard with a built-in buffer layer.

[0030] In one embodiment, a motorcycle chain guard structure with a built-in buffer layer includes: a housing 100, the surface of which is provided with two mounting holes 110;

[0031] The buffer mechanism 300 includes a buffer shell 310 disposed at the top inner side of the housing 100, a buffer plate 320 disposed inside the buffer shell 310, and multiple sets of buffer components 340 disposed between the buffer plate 320 and the inner top wall of the buffer shell 310.

[0032] like Figure 2 , Figure 3 and Figure 4 As shown, a positioning plate 321 is fixedly connected to the lower surface of the buffer plate 320, and multiple rollers 330 are rotatably connected to the lower surface of the positioning plate 321. The buffer assembly 340 includes a cylinder 341 fixedly connected to the inner top wall of the buffer shell 310. A piston plate 3411 is slidably connected inside the cylinder 341, and a spring 3412 is fixedly connected between the piston plate 3411 and the inner top wall of the cylinder 341. A piston rod 342 is fixedly connected to the lower surface of the piston plate 3411. The piston rod 342 is a hollow rod, and its bottom end extends through the cylinder 341. A connecting block 343 is slidably connected to the inner wall of the piston rod 342, and the bottom end of the connecting block 343 is disc-shaped. A limiting plate 345 is fixedly connected to the surface of the piston rod 342. An airbag 344 is provided between the limiting plate 345 and the bottom end of the connecting block 343. The airbag 344 is sleeved on the surface of the connecting block 343. The lower surface of the connecting block 343 is fixedly connected to the buffer plate 320.

[0033] In this embodiment, a rectangular opening is provided at the bottom of the buffer shell 310, and the buffer plate 320 is disposed inside the buffer shell 310. The positioning plate 321 is disposed through the rectangular opening. The rotating roller 330 is embedded in the lower surface of the positioning plate 321 and is cylindrical with both ends rotatably connected to the inner wall of the positioning plate 321. Because the chain contacts the rotating roller 330 during vehicle operation, the chain is in motion. At this time, the chain contacts the rotating roller 330, and the rotation further reduces friction, thereby reducing chain wear. The medium in the cylinder 341 is gas. The chain buffering effect can be adjusted by controlling the amount of gas in the cylinder 341. The more gas in the cylinder 341, the greater the impact force between the chain and the rotating roller 330. The connecting block 343 consists of a circular slider slidably connected to the inner wall of the piston rod 342, a disc-shaped block fixedly connected to the buffer rod, and a connecting rod disposed between the slider and the disc-shaped block. The airbag 344 is sleeved on the connecting rod. When the chain vibration amplitude is small, the airbag 344 can absorb the impact force of the chain to complete the buffering. When the chain vibration amplitude is large, the airbag 344 will be compressed to a certain amount and push the piston to move to complete the shock absorption. At the same time, the characteristics of the cylinder 341 are equivalent to damping the spring 3412 to avoid the problem of repeated oscillation caused by the spring 3412 rebounding after being compressed. Since the deformation of the airbag 344 after being compressed is quite limited, it will not have a substantial impact on the movement of the chain. At the same time, since the buffer component 340 is set inside the buffer shell 310, the airbag 344 is not exposed to the outside world by working with the buffer plate 320, so the airbag 344 will not be affected by external substances.

[0034] It should be noted that the buffer mechanism 300 of this device is cleverly located inside the housing 100, and sufficient space is specially reserved inside the housing 100 to ensure the normal movement of the chain. The buffer mechanism 300 only occupies the top area of ​​the housing 100, so it will not affect the normal installation and operation of the device. When the chain is running normally, the buffer mechanism 300 will not cause any interference; it only activates when the chain is subjected to bumps, providing effective cushioning. Since the chain is kept in a certain slack state during installation, the impact of the buffer mechanism 300 is within a reasonable range and will not adversely affect the smooth movement of the chain. In summary, the buffer mechanism 300 of this device will not cause any interference to the normal operation of the vehicle.

[0035] like Figure 1 and Figure 2 As shown, two bolts 350 are fixedly connected to the upper surface of the buffer shell 310, and two corresponding positioning holes are opened at the top of the shell 100. Multiple through holes 200 are opened on the surface of the shell 100, and the through holes 200 are evenly distributed in a "I" shape.

[0036] In this embodiment, the presence of the through hole 200 can effectively reduce the weight of the housing 100, and the through hole 200 can also provide a certain heat dissipation effect for the housing 100.

[0037] Working principle: First, the buffer mechanism 300 of this device is passed through the mounting hole 110 of the outer shell by bolts 350 and fixed by nuts. Then, this device is installed on the motorcycle through the positioning hole.

[0038] When the vehicle experiences a bump, the chain vibrates, striking the roller 330. This roller 330 then moves the positioning plate 321 and the buffer plate 320 upwards. When the vehicle encounters a small bump, the buffer plate 320 moves upwards only slightly, causing the connecting block 343 to move upwards and compressing the airbag 344. The deformation of the airbag 344 absorbs the impact.

[0039] When the vehicle experiences significant bumps, the vehicle's chain will vibrate dramatically, causing the buffer plate 320 to move upwards to a considerable extent. Once the connecting block 343 compresses the airbag 344 to a certain limit, it will push the piston rod 342 and piston plate 3411 to move upwards within the cylinder 341. The impact force is absorbed by the compression spring 3412 and the gas in the compressed cylinder 341, thus completing the damping.

[0040] It should be noted that the spring 3412, airbag 344 and bolt 350 mentioned above are all components with relatively mature existing technology. The specific models can be selected according to actual needs, and will not be elaborated here.

[0041] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0042] The above-described embodiments are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of this utility model. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the appended claims.
