Description

Technical Field

[0001] The utility model relates to the technical field of unicycles, in particular to a slide bar shock-absorbing adjustment structure and a unicycle. Background Art

[0002] With growing environmental awareness and the diversification of personal travel options, electric unicycles, as a novel, portable, and environmentally friendly means of transportation, are gradually gaining popularity among consumers. With their unique single-wheel design and advanced self-balancing technology, electric unicycles offer users an unprecedented riding experience. However, in existing technologies, electric unicycles, for shock absorption purposes, have a sliding rod sleeve fixedly connected to the wheel. One end of the sliding rod body is connected to a pedal, and the sliding rod body is slidably mounted on the sliding rod sleeve. This ensures that when carrying a person or when carrying a person over bumpy roads, the pedal and the sliding rod body float relative to the sliding rod sleeve, which, combined with the energy absorption of the shock-absorbing assembly, acts as a buffer. After the passenger leaves the pedal or the road surface is flat, the slide rod body and the pedal will rebound upward after being affected by the shock absorbing assembly. In the prior art, a boss is generally provided at the bottom of the slide rod body, which can ensure that when the slide rod body rebounds upward and the boss and the end face of the slide rod sleeve are against each other, the limit of the rebound distance is reached. However, the rebound limit is limited by this structure and cannot be adjusted. However, the rebound stroke required by different users is different. The inability to adjust the rebound stroke will affect the usage experience of different users, and the adaptability is not wide enough. Utility Model Content

[0003] In order to overcome at least one of the defects of the prior art described above, the present invention provides a sliding rod shock-absorbing adjustment structure and a unicycle, which can control the rebound distance of the sliding rod body to meet the usage requirements of different users.

[0004] The technical solution adopted by the present invention to solve the problem is:

[0005] A sliding rod shock-absorbing adjustment structure, comprising:

[0006] Slider body;

[0007] A slide rod sleeve, wherein the slide rod sleeve is provided with a slide hole, the slide hole is arranged along a first direction, and the slide rod body is slidably arranged in the slide hole;

[0008] an adjusting assembly, the adjusting assembly comprising an adjusting member and a limiting member, the adjusting member being assembled on the slide rod body, the limiting member being assembled on the adjusting member, and the limiting member being capable of adjusting a position of the limiting member in the first direction relative to the adjusting member;

[0009] In which, the sliding rod sleeve has an abutment surface facing the adjustment assembly, and the abutment surface is located within the vertical projection range of the limiting member in the first direction. The abutment surface can be used to abut and limit the limiting member to limit the movement range of the sliding rod body relative to the sliding rod sleeve when the sliding rod body slides along the first direction.

[0010] By adopting the above solution, the limit member contacts and limits the slide rod sleeve in advance during the rebound process of the slide rod body, and the limit member can adjust the position of the limit member in the first direction relative to the adjusting member, thereby effectively controlling the rebound distance of the slide rod body. The user can conveniently adjust the rebound distance of the slide rod body according to needs to control the shock absorption stroke to meet the usage requirements of different users.

[0011] Furthermore, based on the structure in which the limit member can adjust the position of the limit member in the first direction relative to the adjusting member, the shock absorption effect can be flexibly adjusted according to different road conditions, the rider's habits and the rider's weight, thereby increasing the adaptability of the unicycle using the shock absorption adjustment structure, that is, the shock absorption adjustment structure can adapt to more road conditions and more types of riders.

[0012] Furthermore, one end of the sliding rod body is connected to a fixing part for installing a pedal, the adjusting part is arranged on the fixing part, the adjusting part is provided with a threaded hole, the limiting part is provided with an external thread that cooperates with the threaded hole, and the adjusting part is threadedly matched with the limiting part.

[0013] By adopting the above solution, the threaded fit between the adjustment member and the limiter allows the user to adjust the position of the limiter according to personal needs or different riding conditions, thereby changing the maximum travel of the slider body relative to the slider sleeve. In other words, the rider can adjust the rebound distance according to their weight or riding style, which helps maintain the stability of the unicycle. The threaded fit design simplifies the installation and removal of the limiter, allowing users to easily adjust or maintain it without the need for special tools or skills.

[0014] Furthermore, there are two adjusting members, which are symmetrically arranged on both sides of the sliding rod body with the axis of the sliding rod body as the symmetry axis, and each of the adjusting members is equipped with a limiting member.

[0015] By adopting the above scheme, the symmetrically designed adjustment parts can provide more balanced support, making the sliding rod body more stable and less prone to deflection during the sliding process. Compared with the single-sided limiter, the double-sided limiter structure can more evenly disperse the pressure, thereby reducing the impact force on a single limiter and extending the service life. In addition, the double-sided limiter structure can also improve the reliability and durability of the entire structure. Even if one of the limiters has a problem, the other can still play a limiting role.

[0016] Furthermore, the surfaces of the two adjusting members facing the slide rod body are contoured surfaces, and the contoured surfaces are in contact with the outer wall of the slide rod body.

[0017] By adopting the above solution, the design of the contoured surface can make the adjusting member fit the sliding rod body more closely, thereby improving the stability of the entire structure.

[0018] Furthermore, the limiting member includes a nail head and a rod, the nail head is fixedly connected to the rod, and a convenient structure is provided on the end face of the nail head away from the rod for controlling the rotation of the nail head, the external thread is provided on the rod, and the rod is passed through the threaded hole.

[0019] By adopting the above solution, since a convenient structure is provided on the nail head, which can be a hexagonal or other shape for easy insertion and rotation of a wrench or special tool, adjusting the position of the limiter becomes more convenient and quick, and the adjustment can be completed without complicated tools or disassembly steps.

[0020] Furthermore, the convenient structure is arranged toward the direction of the adjusting member away from the abutting surface.

[0021] By adopting the above solution, the convenient structure is designed in the direction of the adjustment member away from the abutment surface, that is, toward the bottom surface. No other components are required in this direction of the limiter. During the adjustment process of the limiter, there is no need to remove other components, and the limiter can be operated directly, which simplifies the adjustment process and saves time and effort. In addition, because there are no other components blocking the bottom surface of the adjustment member, the user has a clearer field of view when adjusting the limiter, and the operation is more intuitive, reducing the possibility of misoperation.

[0022] Furthermore, the threaded hole is provided at a position of the adjusting member close to the fixing member.

[0023] By adopting the above solution, since the adjusting part is an extension of the fixing part and the limiting part is assembled on the adjusting part, when the limiting part abuts against the sliding rod sleeve, a force arm is formed between the connection between the adjusting part and the fixing part and the threaded hole. The threaded hole is arranged close to the fixing part to shorten the force arm, thereby reducing damage to the connection between the adjusting part and the fixing part when the limiting part abuts against the sliding rod sleeve.

[0024] Furthermore, the adjusting member and the fixing member are integrally formed.

[0025] By adopting this solution, the integrated molding of the adjusting and fixing parts eliminates the joint between the adjusting and fixing parts, preventing the connection from loosening or breaking due to long-term use, and improving the strength and reliability of the overall structure. Furthermore, the integrated design reduces the number of parts, simplifies the production process, reduces manufacturing costs, and also reduces assembly time and improves production efficiency.

[0026] Furthermore, one end of the sliding rod body is connected to a fixing part, and the fixing part is provided with a plurality of assembly holes along the first direction. The plurality of assembly holes constitute an adjusting part, and the limiting part assembled in any of the assembly holes is located within the vertical projection range of the abutment surface in the first direction.

[0027] By adopting the above solution, the design of multiple assembly holes allows the user to flexibly select the installation position of the limit member according to actual conditions or personal needs, thereby adjusting the movement range of the slide body relative to the slide sleeve to adapt to different riding conditions or rider weight.

[0028] The utility model also provides a wheelbarrow, comprising:

[0029] wheel;

[0030] At least one set of the above-mentioned sliding rod shock-absorbing adjustment structure;

[0031] Wherein, one end of the slide rod body is connected to a pedal, and the end of the slide rod sleeve close to the pedal is fixedly connected to the wheel.

[0032] By adopting the above solution, the sliding rod shock-absorbing adjustment structure can control the range of motion of the sliding rod body relative to the sliding rod sleeve. The sliding rod shock-absorbing adjustment structure allows the user to adjust the position of the limiter according to personal needs and different riding environments, making the unicycle more adaptable to various riding conditions and improving the unicycle's flexibility and adaptability.

[0033] In summary, the slide bar shock-absorbing adjustment structure and the unicycle provided by the present invention have the following technical effects:

[0034] 1. The limiting member contacts and limits the slide rod sleeve in advance during the slide rod body's rebound process, and the limiting member can adjust its position in the first direction relative to the adjusting member, thereby effectively controlling the rebound distance of the slide rod body.

[0035] 2. Based on the structure in which the limit member can adjust the position of the limit member in the first direction relative to the adjusting member, the shock absorption effect can be flexibly adjusted according to different road conditions, rider habits and rider weight, thereby increasing the adaptability of the unicycle using the shock absorption adjustment structure, that is, the shock absorption adjustment structure can adapt to more road conditions and more types of riders.

[0044] For better understanding and implementation, the technical solutions in the embodiments of the present invention will be clearly and completely described and discussed below in conjunction with the drawings of the present invention. Obviously, what is described here is only a part of the examples of the present invention, not all the examples. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0045] In order to facilitate the understanding of the embodiments of the present invention, the following will be further explained with reference to specific embodiments as examples in conjunction with the drawings, and each embodiment does not constitute a limitation on the embodiments of the present invention.

[0046] In the description of the present invention, it should be noted that the terms "upper", "lower", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings. They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction. Therefore, they cannot be understood as limiting the present invention.

[0047] 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.

[0048] See Figure 1-Figure 3 As shown, the utility model discloses a sliding rod shock-absorbing adjustment structure, including a sliding rod body 1, a sliding rod sleeve 2 and an adjustment assembly 3. The sliding rod sleeve 2 is provided with a sliding hole 21, and the sliding hole 21 is arranged along a first direction. The sliding rod body 1 is slidably arranged in the sliding hole 21. The adjustment assembly 3 includes an adjusting member 31 and a limiting member 32. The adjusting member 31 is assembled on the sliding rod body 1, and the limiting member 32 is assembled on the adjusting member 31, and the limiting member 32 can adjust the position of the limiting member 32 in the first direction relative to the adjusting member 31. Among them, the sliding rod sleeve 2 has an abutting surface 22 facing the adjustment assembly 3. The abutting surface 22 can be specifically the end surface of the sliding rod sleeve 2 facing the side of the adjustment assembly 3 or a surface extended as required. The abutting surface 22 is located within the vertical projection range of the limiting member 32 in the first direction, so as to limit the movement range of the sliding rod body 1 relative to the sliding rod sleeve 2 when the sliding rod body 1 slides along the first direction.

[0049] Specifically, the slide sleeve 2 is provided with a sliding hole 21, and the sliding hole 21 is arranged along the first direction. Correspondingly, the slide body 1 slidably arranged in the sliding hole 21 slides along the first direction. The adjustment assembly 3 includes an adjustment member 31 and a limit member 32. The adjustment member 31 is assembled on the slide body 1, and the limit member 32 is assembled on the adjustment member 31. The limit member 32 can adjust the position of the limit member 32 in the first direction relative to the adjustment member 31, that is, the limit member 32 can move in the first direction. The end face of the slide sleeve 2 facing the adjustment assembly 3 is an abutment surface 22. The abutment surface 22 is located within the vertical projection range of the limit member 32 in the first direction. That is, when the limit member 32 moves with the slide body 1, the limit member 32 will abut against the abutment surface 22, thereby achieving the effect of limiting the range of motion of the slide body 1 relative to the slide sleeve 2. The range of motion mainly refers to the range of motion to prevent the slide body 1 from rebounding.

[0050] In this embodiment, the abutment surface 22 is the bottom surface of the slide rod sleeve 2, and the abutment surface 22 is located within the vertical projection range of the limit member 32 in the first direction, thereby ensuring that when the slide rod body 1 moves along the first direction, the limit member 32 preferentially contacts the abutment surface 22, thereby limiting the rebound limit range of the slide rod body 1.

[0051] The way the adjusting member 31 is assembled to the sliding rod body 1 can be selected to be fixedly connected to the sliding rod body 1, or it can be selected to be installed on other external mounting carriers and connection methods, which can ensure that during the rebound process of the sliding rod body 1, the adjusting member 31 moves along with the movement of the sliding rod body 1, and the limiting member 32 provided on the adjusting member 31 can preferentially contact the abutting surface 22. The specific matching method of the adjusting member 31 and the limiting member 32 can be that the limiting member 32 moves telescopically relative to the adjusting member 31, or the adjusting member 31 is provided with a plurality of positions for assembling the limiting member 32, so as to meet the adjustment of the position of the limiting member 32 in the first direction. Of course, the adjusting member 31 and the limiting member 32 can also adopt other matching methods, which can meet the movement of the limiting member 32 in the first direction relative to the adjusting member 31. See. Figure 1-Figure 3 As shown, in some embodiments, in order to facilitate the installation of the adjusting member 31 and the adjustment of the limiting member 32, one end of the sliding rod body 1 is connected to the fixing member 4, the adjusting member 31 is arranged on the fixing member 4, the adjusting member 31 is provided with a threaded hole 311, the limiting member 32 is provided with an external thread that cooperates with the threaded hole 311, and the adjusting member 31 is threadedly matched with the limiting member 32.

[0052] Specifically, one end of the slide body 1 is connected to a fixing member 4, and an adjusting member 31 is installed on the fixing member 4. The adjusting member 31 is provided with a threaded hole 311, and a limiting member 32 is provided with an external thread that cooperates with the threaded hole 311. The adjusting member 31 and the limiting member 32 are threadedly engaged. By rotating the limiting member 32, the movement of the limiting member 32 relative to the adjusting member 31 in the first direction can be controlled. Through the threaded engagement between the adjusting member 31 and the limiting member 32, the user can adjust the position of the limiting member 32 according to personal needs or different riding conditions, thereby changing the maximum stroke of the slide body 1 relative to the slide sleeve 2, that is, the rider can adjust the appropriate rebound distance according to his or her weight or riding style, which helps to maintain the stability of the unicycle. The threaded engagement design makes the installation and removal of the limiting member 32 simple, convenient for users to adjust or maintain by themselves, and does not require special tools or skills. In this embodiment, the fixing member 4 is used to install the pedal 6, thereby achieving the synchronous movement of the pedal 6 and the slide body 1.

[0053] See Figure 5 As shown, in some embodiments, in order to improve the service life of the adjusting member 31 and the limiting member 32, two adjusting members 31 are provided, and the two adjusting members 31 are symmetrically arranged on both sides of the sliding rod body 1 with the axis of the sliding rod body 1 as the symmetry axis, and each adjusting member 31 is equipped with a limiting member 32.

[0054] Specifically, there are two adjusting members 31, and the two adjusting members 31 are symmetrically arranged on both sides of the sliding member 1 with the axis of the sliding member 1 as the axis of symmetry, and each adjusting member 31 is equipped with a limit member 32. As a preference, since the sliding member 1 will be assembled close to the wheel 5 in the subsequent assembly, the two adjusting members 31 are both arranged on the side of the sliding member 1 away from the wheel 5, and it is best to set them symmetrically with the axis of the sliding member 1 as the axis of symmetry. The symmetrically designed adjusting members 31 can provide more balanced support, making the sliding member 1 more stable and less prone to deflection during the sliding process. The structure of the double-sided limit members 32 can more evenly distribute the pressure received than the single-sided limit member 32, thereby reducing the impact force on a single limit member 32 and extending the service life. In addition, the structure of the double-sided limit members 32 can also improve the reliability and durability of the entire structure. Even if one of the limit members 32 has a problem, the other can still play a limiting role.

[0055] See Figure 4 and Figure 5 As shown, based on the structure in which two adjusting members 31 are provided, the surfaces of the two adjusting members 31 facing the slide body 1 are contoured surfaces 41 , and the contoured surfaces 41 are in contact with the outer wall of the slide body 1 .

[0056] Specifically, the surface of the adjusting member 31 facing the slide body 1 is a contoured surface 41, and the contoured surface 41 is set to correspond to the outer surface of the slide body 1 so that the contoured surface 41 fits the outer wall of the slide body 1, thereby compressing the assembly area of the adjusting member 31 and the slide body 1. In addition, the design of the contoured surface 41 can make the adjusting member 31 fit more closely to the slide body 1, thereby improving the stability of the entire structure.

[0057] See Figure 6 As shown, in this embodiment, in order to facilitate the adjustment of the limit member 32, the limit member 32 includes a nail head 321 and a rod 322. The nail head 321 is fixedly connected to the rod 322. A convenient structure 323 is provided on the end face of the nail head 321 away from the rod 322 for controlling the rotation of the nail head 321. An external thread is provided on the rod 322, and the rod 322 is passed through the threaded hole 311.

[0058] Specifically, since a convenient structure 323 is provided on the nail head 321, the convenient structure 323 can be a hexagonal or other shaped groove or protrusion to facilitate the insertion and rotation of a wrench or special tool, making it more convenient and quick to adjust the position of the limit member 32, and the adjustment can be completed without complicated tools or disassembly steps.

[0059] See Figure 2 and Figure 6 As shown, in this embodiment, in order to facilitate the adjustment of the position of the limiting member 32 , the convenient structure 323 is arranged in a direction toward the adjusting member 31 away from the abutting surface 22 .

[0060] Specifically, the convenient structure 323 is designed in the direction away from the abutment surface 22 of the adjusting member 31, that is, toward the bottom surface. This eliminates the need for additional components in this direction of the limiter 32. During adjustment of the limiter 32, there is no need to remove other components; the limiter 32 can be operated directly, simplifying the adjustment process and saving time and effort. Furthermore, since there are no other components blocking the bottom surface of the adjusting member 31, the user has a clearer field of view when adjusting the limiter 32, making the operation more intuitive and reducing the possibility of misoperation.

[0061] See Figure 5 As shown, in some embodiments, in order to improve the service life of the connection between the adjusting member 31 and the fixing member 4 , the threaded hole 311 is provided at a position of the adjusting member 31 close to the fixing member 4 .

[0062] Specifically, since the adjusting member 31 is an extension of the fixing member 4, and the limiting member 32 is assembled on the adjusting member 31, when the limiting member 32 abuts against the sliding rod sleeve 2, a force arm is formed between the connection between the adjusting member 31 and the fixing member 4 and the threaded hole 311. The threaded hole 311 is arranged close to the fixing member 4 to shorten the force arm, thereby reducing damage to the connection between the adjusting member 31 and the fixing member 4 when the limiting member 32 abuts against the sliding rod sleeve 2.

[0063] See Figure 4 and Figure 5 As shown, in some embodiments, in order to improve the strength of the adjusting member 31 and the fixing member 4 , the adjusting member 31 and the fixing member 4 are integrally formed.

[0064] Specifically, by integrating the adjusting member 31 and the fixing member 4 into a single piece, the joint between the adjusting member 31 and the fixing member 4 is eliminated, preventing the connection from loosening or breaking due to prolonged use, thereby improving the strength and reliability of the overall structure. Furthermore, the integrated design reduces the number of parts, simplifies the production process, lowers manufacturing costs, and reduces assembly time, thereby improving production efficiency. Alternatively, when two adjusting members 31 are provided, both adjusting members 31 can be integrally formed with the fixing member 4, thereby further improving the strength between the fixing member 4 and the adjusting member 31.

[0065] In some embodiments, one end of the sliding rod body 1 is connected to a fixing member 4, and the fixing member 4 is provided with multiple assembly holes along the first direction. The multiple assembly holes constitute an adjusting member 31, and the limiting member 32 assembled in any assembly hole is located within the vertical projection range of the abutment surface 22 in the first direction.

[0066] Specifically, one end of the slide body 1 is connected to a fixing member 4, which is provided with a plurality of mounting holes along a first direction. These mounting holes constitute an adjustment member 31, and the limiting member 32, when assembled in any of the mounting holes, is located within the vertical projection of the abutment surface 22 in the first direction. This ensures that the limiting member 32 can abut against the abutment surface 22 in any of the mounting holes. The position of the limiting member 32 in the first direction can be adjusted by adjusting the specific position of the limiting member 32 in the mounting hole. The multiple mounting holes can be arranged in an evenly spaced or other arrangement as needed.

[0067] See Figure 7 As shown, the utility model also provides a unicycle, including wheels 5 and at least one set of the above-mentioned slide rod shock absorption adjustment structure, wherein one end of the slide rod body 1 is connected to a pedal 6, and the end of the slide rod sleeve 2 close to the pedal 6 is fixedly connected to the wheel 5.

[0068] Specifically, the wheel 5 is fixedly connected to the slide rod sleeve 2, the slide rod body 1 is slidably arranged in the slide rod sleeve 2, and the lower end of the slide rod body 1 is connected to the pedal 6. The adjusting member 31 can be optionally arranged at the slide rod body 1 to ensure that when the slide rod body 1 rebounds, the limit member 32 abuts against the abutting surface 22 of the slide rod sleeve 2. The rebound limiting effect can be achieved by setting a slide rod shock-absorbing adjustment structure on one side of the wheel 5. As another optional solution, a group of slide rod shock-absorbing adjustment structures can also be set on both sides of the wheel 5. This is more conducive to uniformly bearing the impact force and improving the service life of the slide rod shock-absorbing adjustment structure.

[0069] 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.
