Description

Technical Field

[0001] This application relates to the field of bicycle accessory technology, and in particular to a bicycle kickstand with shock absorption and cushioning function. Background Technology

[0002] Bicycles serve as their primary mode of transportation, offering advantages such as being noiseless, pollution-free, lightweight, simple in structure, inexpensive, and easy to use and maintain. Bicycles typically have kickstands mounted on the rear rack, allowing the detachable kickstands to be lowered for support when parking.

[0003] Existing bicycle kickstands can be fixed in both the folded and active states through the mounting structure. However, the kickstands are fixed solely through the mounting structure. The springs / clips and screws used for fastening are prone to fatigue and aging due to frequent bumps and vibrations during bicycle riding. This causes the kickstands to vibrate and make abnormal noises before reaching their designed service life. Summary of the Invention

[0004] The purpose of this application is to provide a bicycle kickstand that reduces vibration and thus wear during riding.

[0005] To achieve the above objectives, the technical solution adopted in this application is as follows: a bicycle kickstand with shock absorption and cushioning function, comprising a retractable kickstand body and a support structure, wherein the support structure and the retractable kickstand body in the retracted state are connected at a joint to prevent the kickstand body from shifting in the retracted state.

[0006] As a preferred embodiment, the support structure includes an annular locking block adapted to the connection point. The annular locking block has two coaxially aligned support holes with different radii connected end to end. The bottom of each support hole has an opening for the passage of the support body. The width of each opening is smaller than the diameter of the two ends of the connection point of the support body.

[0007] More preferably, the annular locking block is provided with an extension portion and a mounting portion, the mounting portion being fixedly connected to the bicycle frame, and the extension portion creating a gap between the annular locking block and the bicycle frame.

[0008] More preferably, each of the support holes is provided with a fastening block for clamping the support body on its inner side. The fastening block is located on the inner side of the opening and is formed with a V-shaped conical surface or an arc-shaped arch surface.

[0009] More preferably, each of the support holes is provided with a clamping pad on its inner side, the clamping pad being made of an elastically deformable material; when the two sides of the connection of the support body are respectively inserted into the two support holes, the clamping pad is acted upon and deformed.

[0010] More preferably, the wall of the support hole is provided with a groove for fixing the clamping pad, the bottom of the clamping pad is formed in the locking part, and the groove and the locking part are T-shaped structures that are matched. During installation, the locking part deforms and enters into the groove for fixing.

[0011] As another preferred embodiment, the support structure includes a fixing part for fixed installation with the bicycle frame and a first limiting part and a second limiting part for respectively engaging and limiting the connection points of the support body on both sides. The first limiting part and the second limiting part both have circular inner cavities and are coaxially arranged. The bottom of the first limiting part and the second limiting part are provided with passage openings for the support body to pass through. The width of the passage openings is smaller than the diameters of the two ends of the connection point of the support body.

[0012] More preferably, the first limiting part and the second limiting part are integrally formed on the same fixing part, and the circular inner diameters of the first limiting part and the second limiting part are respectively larger than the inner diameters at both ends of the support body connection. Both the first limiting part and the second limiting part are provided with elastic pads on their inner walls. After the elastic pads are installed, the inner diameters of the first limiting part and the second limiting part are reduced to the diameters at both ends of the support body connection.

[0013] As a preferred embodiment, the kickstand body includes two interlocking support rods and an adjustment part for fixing the length. The bicycle kickstand also includes a mounting structure for installation, which fixes the kickstand body in the use state and the folded state.

[0014] Compared with the prior art, the beneficial effects of this application are as follows:

[0015] The support structure works in conjunction with the connection point of the support body. On the one hand, it supports the other side of the support body, and on the other hand, setting it at this position can also ensure that the connection point of the support body receives sufficient support. Setting the support structure at this position can reduce damage to both the installation structure and the connection point of the support body, effectively improving the life of the support leg.

[0027] It should be noted that the terms "first," "second," etc., in the specification and claims of this application are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence.

[0028] The terms “comprising” and “having”, and any variations thereof, in the specification and claims of this application are intended to cover non-exclusive inclusion, for example, a process, method, system, product, or device that includes a series of steps or units is not necessarily limited to those steps or units that are explicitly listed, but may include other steps or units that are not explicitly listed or that are inherent to such process, method, product, or device.

[0029] Example:

[0030] Reference Figures 1 to 8 This embodiment proposes a bicycle kickstand with shock absorption and cushioning function, including a retractable kickstand body 3 and a support structure 5. The support structure 5 and the retracted kickstand body 3 are connected at an adjustable joint to prevent displacement of the kickstand body 3 in the retracted state. Preferably, the kickstand body 3 includes two interlocking support rods and an adjustment part for length fixation. The bicycle kickstand also includes a mounting structure 2 for installation, which fixes the kickstand body 3 in both the used and retracted states. Figure 2 As shown, the connection point of the support body 3 corresponds to the end of the larger support rod.

[0031] The function of support structure 5 is to provide auxiliary support to the other side of the kickstand (the side different from the mounting structure 2). During bicycle riding, due to the small size of the tires, the cushioning capacity is relatively weak. Especially since the kickstand is generally mounted on the frame 1, the bicycle's bumps are directly transmitted to the frame 1. Furthermore, the kickstand is usually only fixed by mounting structure 2, causing fatigue and aging of mounting structure 2 before the existing kickstand reaches its designed lifespan. After mounting structure 2 ages, the fixed end of the kickstand becomes unstable, and bumps cause frequent vibration of the kickstand body 3, resulting in frequent abnormal noises and friction, thus affecting the riding experience and even damaging the bicycle (e.g., scratching the paint on frame 1). Support structure 5 works at the connection point of the kickstand body 3, providing support to the other side of the kickstand body 3. Its location at the connection point also ensures sufficient support for the connection of the kickstand body 3. The connection point of the kickstand body 3 is generally tightened and loosened with a single screw, and the bumps during bicycle riding also cause wear at this point. Therefore, the support structure provides support and cushioning to reduce damage caused by vibration. In summary, compared to setting support structures in other locations, setting support structure 5 in this location can simultaneously reduce damage at the connection between installation structure 2 and support leg body 3, effectively improving the lifespan of the support leg.

[0032] Two preferred schemes for support structure 5 are proposed below for reference.

[0033] (1) The first preferred support structure 5 includes an annular locking block adapted to the connection point. The annular locking block has two coaxially aligned support holes with different radii connected end-to-end. The bottom of each support hole has an opening for the passage of the support column 3. The width of each opening is smaller than the diameter of the two ends of the connection point of the support column 3. (Refer to...) Figure 4 , Figure 5 The annular locking block may include a first locking block 53 and a second locking block 54, with the two blocks forming two support holes respectively. Alternatively, the annular locking block can be integrally formed, with similar support holes provided within the inner cavity. Figure 5 As shown, the opening at the bottom is used to enter when the support leg is retracted. During the entry process, the opening can be used to deform the bottom of the annular locking block to avoid it. Then, the connection of the support leg body 3 is located in the support hole for support.

[0034] like Figure 7 As shown, the annular locking block has an extension 6 and a mounting part 4. The mounting part 4 is fixedly connected to the bicycle frame 1, and the extension 6 creates a gap between the annular locking block and the bicycle frame 1. The mounting part 4 can be a C-clamp and fixed with screws.

[0035] Each support hole has a fastening block 7 on its inner side for clamping the support body 3. The fastening block 7 is located inside the opening and is formed with a V-shaped conical surface or an arc-shaped arch surface. The fastening block 7 is as follows: Figure 6 As shown, Figure 6 Although this is a schematic diagram of the second type of support structure 5, the corresponding fastening block 7 can also be installed in this support structure 5. The following clamping pad 8, elastic pad and other related structures can also be used interchangeably. The purpose of the different descriptions in this embodiment is to facilitate explanation.

[0036] like Figure 8 As shown, each support hole has a clamping pad 8 on its inner side. The clamping pad 8 is made of a material that can be elastically deformed. When the two sides of the connection of the support body 3 are respectively inserted into the two support holes, they act on the clamping pad 8 and deform the clamping pad 8.

[0037] like Figure 7 As shown, the wall of the support hole is provided with a groove for fixing the clamping pad 8. The bottom of the clamping pad 8 is formed in the locking part. The groove and the locking part are T-shaped structures 9 that fit together. During installation, the locking part deforms and fits into the groove for fixing. Of course, the clamping pad 8 can also be installed by means of adhesive or other methods.

[0038] (2) such as Figure 2 , Figure 3The second type of support structure 5 includes a fixing part for fixed installation with the bicycle frame 1 and a first limiting part 51 and a second limiting part 52 for respectively engaging and limiting the connection with both sides of the support body 3. The first limiting part 51 and the second limiting part 52 both have circular inner cavities and are coaxially arranged. The bottom of the first limiting part 51 and the second limiting part 52 are provided with a passage for the support body 3 to pass through. The width of the passage is smaller than the diameter of the two ends of the connection of the support body 3. The main difference between the second type of support structure 5 and the first type of support structure 5 is that the first locking block 53 and the second locking block 54 of the first type of support structure 5 are set together or integrally formed, while the first limiting part 51 and the second limiting part 52 of the second type of support structure 5 are set separately. When the support body 3 is retracted, the second type of support structure 5 is relatively flexible and easy to deform because the first limiting part 51 and the second limiting part 52 are set separately. Therefore, in actual operation, the force of kicking the support foot is sufficient to deform the support body 3, making it more convenient to use.

[0039] like Figure 2 As shown, the first limiting part 51 and the second limiting part 52 are integrally formed on the same fixing part, and the inner diameter of the first limiting part 51 and the second limiting part 52 is larger than the inner diameter of both ends of the connection of the support body 3.

[0040] like Figure 6 , Figure 7 Both the inner walls of the first limiting part 51 and the second limiting part 52 are provided with elastic pads. After the elastic pads are installed, the inner diameters of the first limiting part 51 and the second limiting part 52 are reduced to the diameters at both ends of the connection of the support body 3. The elastic pads and the clamping pads 8 referred to in this application have similar or identical structures and are both elastic and deformable pads, the purpose of which is to secure the device.

Those skilled in the art should understand that this application is not limited to the above embodiments. The embodiments and descriptions in the specification are merely the principles of this application. Various changes and modifications can be made to this application without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims.
