Description

Technical Field

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

[0002] With the diversification of personal travel modes, the unicycle, as a convenient and environmentally friendly short-distance transportation tool, has been favored by more and more users. However, since the unicycle encounters various road conditions during driving, shock absorption performance has become one of the important indicators to measure the comfort and safety of the unicycle.

[0003] Existing unicycles are typically equipped with shock-absorbing components to absorb vibration and impact during travel, improving rider comfort and protecting the vehicle's internal structure from damage. These shock-absorbing components typically include springs and shock absorbers, which work together to achieve effective cushioning. While these shock-absorbing devices can significantly improve the riding experience, they also present some practical challenges.

[0004] When the shock absorber assembly needs to be repaired or replaced, especially when removing and installing the spring, current products on the market generally require disassembly of most or all of the upper components of the unicycle. This not only complicates maintenance work but may also require the removal of the electronic control components. This design greatly increases the difficulty of repair and may cause unnecessary interference or even damage to other non-faulty components. In addition, frequent removal and installation of the upper components may also affect the tightness of their connections, thereby introducing additional risk factors to the unicycle. Utility Model Content

[0005] In order to overcome at least one of the defects of the above-mentioned prior art, the present invention provides a shock-absorbing frame and a wheelbarrow thereof, which can solve the problem that the upper components of the wheelbarrow need to be removed during the maintenance of the shock-absorbing assembly, thereby causing maintenance difficulties.

[0006] The technical solution adopted by the present invention to solve the problem is:

[0007] A shock-absorbing frame, comprising:

[0008] A frame body, the frame body comprising a first frame body and a second frame body, the first frame body being provided with an assembly hole, the first frame body being provided with a limiting plate for covering the assembly hole at the assembly hole, the limiting plate being detachably connected to the first frame body;

[0009] A shock absorbing assembly, the shock absorbing assembly comprising a spring and a shock absorber, the spring being sleeved on the shock absorber, and the shock absorber being provided with a limiting block for limiting the spring;

[0010] In which, the shock absorber is arranged along the direction of the assembly hole, and one end of the shock absorber is detachably connected to the limit plate, and the other end is fixedly connected to the second frame body, so that the first frame body can move relative to the second frame body, and one end of the spring is against the limit block, and the other end is against the limit plate.

[0011] By adopting the above solution, by providing a detachable stop plate on the first frame body, when the spring or shock absorber in the shock absorber assembly needs to be maintained, inspected, or replaced, the stop plate can be removed to directly repair or replace the shock absorber assembly, without having to disassemble most or all of the upper components. This structure greatly simplifies the maintenance process and reduces maintenance costs and time.

[0012] When the assembly hole is sized to match the spring, the spring can be quickly repaired or replaced through the hole. Similarly, when the assembly hole is sized to match the shock absorber, the shock absorber can also be quickly repaired or replaced through the hole. Because the shock absorber assembly can be installed and removed directly through the assembly hole, replacement of related components can be completed quickly, effectively improving maintenance efficiency. Furthermore, this structure reduces the risk of damage to other components caused by removing and installing the upper cover.

[0013] Furthermore, the first frame body includes an upper cover plate, and the assembly hole is provided on the upper cover plate.

[0014] By adopting the above solution and providing assembly holes on the upper cover plate, when the spring or shock absorber needs to be maintained, inspected or replaced, it is only necessary to remove the limit plate to perform the operation without removing most or all of the upper components, which greatly simplifies the repair and replacement process and reduces the difficulty of maintenance.

[0015] Furthermore, the upper cover plate is provided with an avoidance groove, the assembly hole is provided at the bottom of the avoidance groove, and the limiting plate is provided in the avoidance groove.

[0016] By adopting the above solution, the arrangement of the avoidance groove shortens the distance between the limit plate and the shock-absorbing assembly, facilitating the installation and removal of the shock-absorbing assembly. This structure facilitates a compact design, thereby reducing the need for operating space and making maintenance work more efficient and convenient.

[0017] In addition, the setting of the avoidance groove ensures the short-distance connection between the limit plate and the shock absorbing assembly (spring and shock absorber) without affecting the upward bulge of other parts of the upper cover, providing sufficient installation space for assembling other parts or for wheels, thereby ensuring that the overall design of the unicycle is compact and not crowded, while retaining sufficient space for installing other necessary components, such as the installation of electronic control components or the avoidance of wheels.

[0018] Furthermore, two or more battery boxes are provided on one side of the first frame body, wherein a gap is provided between two of the battery boxes for assembling the shock absorber and the spring, one end of the gap constitutes an assembly hole, and the limit plate can be detachably assembled at the assembly hole of the first frame body.

[0019] By adopting this solution, the gap between the battery boxes is used to house the shock-absorbing assembly, effectively utilizing the space within the frame and avoiding any additional volume or weight. This compact design ensures the unicycle's lightness and compactness without affecting the overall structural layout and aesthetics. The corresponding positioning of the limit plate in the assembly hole formed by the gap between two adjacent battery boxes allows for convenient maintenance and replacement of the shock-absorbing assembly within this compact unicycle structure.

[0020] Furthermore, the limiting plate is detachably mounted on one or two of the battery boxes adjacent to the limiting plate.

[0021] By adopting this solution, with the stopper plate removably mounted on one or both adjacent battery boxes, when the shock absorber assembly (spring and shock absorber) needs to be maintained, inspected, or replaced, simply remove the stopper plate to gain direct access to the shock absorber assembly. This eliminates the need to remove the entire upper cover and the electronic control assembly above it, greatly simplifying the repair and replacement process and reducing maintenance difficulty.

[0022] More importantly, users can freely choose to install the limit plate on one or both battery compartments, depending on their needs. Installing on one battery compartment facilitates production and removal, making it suitable for applications requiring high production efficiency; while installing on both battery compartments provides greater stability, making it suitable for applications requiring higher structural strength. This flexibility makes the design more adaptable to different usage scenarios and needs.

[0023] Furthermore, the battery box adjacent to the limiting plate is provided with an extension portion toward the limiting plate, and the limiting plate includes a limiting portion and a connecting portion, both ends of the limiting portion are connected to the connecting portion, the limiting portion and the connecting portion connected to its two ends are N-shaped, the extension portion and the connecting portion are detachably connected, and the limiting portion is against the spring.

[0024] By adopting this solution, the N-shaped retaining plate has a dedicated connection portion for the extension. Compared to a thinner plate-like structure, this provides more space for connection with the extension. This not only increases the number of connection points but also provides a larger contact area, thereby improving the stability of the connection. Furthermore, the N-shaped retaining plate design provides more connection space, making it easier to align and secure the connection portion and extension during assembly, reducing the difficulty of assembly.

[0025] Furthermore, the extension portion is located on the outside of the battery box, the extension portion is provided with a first connecting hole, the connecting portion is provided with a second connecting hole on the side facing the extension portion, and the extension portion and the connecting portion are connected by screws or bolts passing through the first connecting hole and the second connecting hole.

[0026] By adopting the above solution, the extension portion is located outside the battery box, making the connection point between the connecting portion and the extension portion easily accessible. The screws or bolts can be easily removed and installed using a simple tool (such as a screwdriver), greatly simplifying the maintenance and replacement process.

[0027] Furthermore, the limiting plate is provided with an avoidance hole, the shock absorber is provided with a damping adjustment component, the damping adjustment component has an adjustment knob, and the adjustment knob is arranged through the avoidance hole.

[0028] By adopting the above solution, a clearance hole is provided in the limit plate, through which the adjustment knob inside the shock absorber can pass, allowing the user to adjust the damping force directly from the outside. This structure does not require the removal of the limit plate or other components, greatly simplifying the adjustment process and improving user convenience.

[0029] Furthermore, the first frame body is a movable frame, the second frame body is a fixed frame, the movable frame and the fixed frame are connected via the shock absorber, and the assembly hole is provided on the top of the first frame body.

[0030] By adopting the above solution, the assembly hole is provided at the top of the first frame body, and the assembly and disassembly can be performed when the wheelbarrow is in a normal upright state. That is, the user or maintenance personnel does not need to turn over or tilt the wheelbarrow, and can directly perform maintenance work when the vehicle is upright, which further simplifies the maintenance process and improves maintenance efficiency.

[0031] The utility model also provides a unicycle, comprising the above-mentioned shock-absorbing frame.

[0032] The detachable retaining plate design makes maintenance and replacement of the shock-absorbing components (spring and shock absorber) much simpler and faster. Users or maintenance personnel only need to remove the retaining plate to directly access the shock-absorbing components, without having to remove the entire upper cover and the electronic control components above, significantly reducing maintenance difficulty and time costs.

[0033] Because the shock absorber assembly can be installed and removed directly through the assembly holes, related parts can be replaced quickly. This design not only improves maintenance efficiency but also reduces the risk of damage to other components caused by frequent disassembly and assembly.

[0034] In summary, the shock-absorbing frame and unicycle provided by the present invention have the following technical effects:

[0035] 1. By providing a detachable stop plate on the first frame body, maintenance, inspection, or replacement of the spring or shock absorber in the shock absorber assembly can be performed directly by simply removing the stop plate, without disassembling most or all of the upper components. This structure greatly simplifies the maintenance process and reduces maintenance costs and time.

[0036] 2. When the assembly hole is sized to match the spring, the spring can be quickly repaired or replaced through the assembly hole. When the assembly hole is sized to match the shock absorber, the shock absorber can also be quickly repaired or replaced through the assembly hole. Because the shock absorber assembly can be directly installed and removed through the assembly hole, the relevant components can be replaced quickly, effectively improving maintenance efficiency.

[0037] 3. In addition to reducing the number of parts that need to be disassembled when repairing the shock-absorbing assembly, this structure also reduces the risk of damage to other parts caused by disassembly and assembly of the upper cover. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0045] 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.

[0046] 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.

[0047] 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.

[0048] 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.

[0049] See Figures 1-6The utility model discloses a shock-absorbing frame, including a frame body 1 and a shock-absorbing assembly 2, a first frame body 11 and a second frame body 12, the first frame body 11 is provided with an assembly hole 13, the first frame body 11 is provided with a limiting plate 14 for covering the assembly hole 13 at the assembly hole 13, the limiting plate 14 is detachably connected to the first frame body 11, the shock-absorbing assembly 2 includes a spring 21 and a shock absorber 22, the spring 21 is sleeved on the shock absorber 22, the shock absorber 22 is provided with a limiting block 221 for limiting the spring 21, wherein the shock absorber 22 is arranged along the direction of the assembly hole 13, and one end of the shock absorber 22 is detachably connected to the limiting plate 14, and the other end is fixedly connected to the second frame body 12, so that the first frame body 11 can move relative to the second frame body 12, one end of the spring 21 is against the limiting block 221, and the other end is against the limiting plate 14.

[0050] Specifically, the frame body 1 includes a first frame body 11 and a second frame body 12. The first frame body 11 is provided with an assembly hole 13. The first frame body 11 is provided with a limiting plate 14 for covering the assembly hole 13 at the assembly hole 13. The limiting plate 14 is detachably connected to the first frame body 11. The detachable connection method of the limiting plate 14 and the first frame body 11 can be selected from a snap connection, a screw connection, or other connection methods that are easy to disassemble. The shock absorber assembly 2 includes a spring 21 and a shock absorber 22. The spring 21 is sleeved on the shock absorber 22. The shock absorber 22 is provided with a limit block 221 for limiting the spring 21. One end of the shock absorber 22 is detachably connected to the limit plate 14 to facilitate the disassembly of the shock absorber 22 relative to the limit plate 14, thereby facilitating the maintenance and replacement of the shock absorber 22 or the spring 21. The other end of the shock absorber 22 is fixedly connected to the second frame body 12 so that the first frame body 11 can float relative to the second frame body 12. One end of the spring 21 is abutted against the limit block 221, and the other end is abutted against the limit plate 14. The limit block 221 can be set to multiple or annularly arranged on the outer surface of the shock absorber 22 as needed to achieve effective abutment with the spring 21. The spring 21 is used to provide energy absorption and push the first frame body 11 to reset relative to the second frame body 12.

[0051] The working principle of the above structure is:

[0052] When the shock-absorbing frame is applied to a unicycle, when traveling on a flat road, the spring 21 is in a natural state, the first frame body 11 and the second frame body 12 remain relatively stationary, and the shock absorber 22 does not produce significant compression or extension. When the unicycle encounters bumps or impacts on the road, the first frame body 11 moves up and down relative to the second frame body 12. The spring 21 is compressed or stretched, absorbing and dissipating vibration energy. The elastic properties of the spring 21 enable it to provide energy absorption and reduce the vibration transmitted to the rider. The damping mechanism (such as oil or air pressure) inside the shock absorber 22 further absorbs the vibration energy and slows down the movement speed of the first frame body 11 through the damping force, thereby improving riding comfort. The limit block 221 ensures that the spring 21 will not separate from the shock absorber 22 during movement, maintaining a stable working state.

[0053] When the shock absorber assembly 2 needs to be maintained or replaced, the limit plate 14 can be removed to directly access the shock absorber assembly 2. The size of the corresponding assembly hole 13 can be set as needed. If only the spring 21 needs to be repaired or replaced, the size of the assembly hole 13 can be set to match only the spring 21, and the spring 21 can be quickly repaired or replaced through the assembly hole 13. When the assembly hole 13 is required for the repair or replacement of the entire shock absorber assembly 2, the size of the assembly hole 13 can be set to match the shock absorber 22, and then the shock absorber 22 can be quickly repaired or replaced through the assembly hole 13. This allows the replacement of related components of the shock absorber assembly 2 to be completed, effectively improving maintenance efficiency.

[0054] See Figure 3 and Figure 4 As shown, in some embodiments, the first frame body 11 includes an upper cover plate 15 , and the assembly hole 13 is provided on the upper cover plate 15 .

[0055] Specifically, the upper cover 15 is a cover on the top of the first frame body 11, and the assembly hole 13 is provided on the upper cover 15. Correspondingly, the limit plate 14 is detachably assembled at the assembly hole 13 of the upper cover 15. Therefore, when the spring 21 or the shock absorber 22 needs to be maintained, inspected or replaced, it is only necessary to remove the limit plate 14, without removing most or all of the upper components, which greatly simplifies the repair and replacement process and reduces the difficulty of maintenance.

[0056] See Figure 3 and Figure 4 As shown, based on the structure in which the assembly hole 13 is provided on the upper cover plate 15 , in order to facilitate the installation of the limit plate 14 , the upper cover plate 15 is provided with an avoidance groove 1511 , the assembly hole 13 is provided at the bottom of the avoidance groove 1511 , and the limit plate 14 is provided in the avoidance groove 1511 .

[0057] Specifically, the setting of the avoidance groove 1511 shortens the distance between the limit plate 14 and the shock absorbing assembly 2, facilitating the installation and disassembly of the shock absorbing assembly 2. This structure is conducive to a compact design, thereby reducing the demand for operating space, making maintenance work more efficient and convenient. In addition, the bottom of the avoidance groove 1511 can also be set to a flat structure, which can also facilitate the assembly of the limit plate 14 and improve the stability of the limit plate 14 after assembly. In addition, based on the structure of the avoidance groove 1511, it will not affect the convexity of other parts of the upper cover plate 15, such as providing sufficient installation space for assembling other parts or for wheels, thereby ensuring that the overall design of the wheelbarrow is compact and not crowded, while retaining enough space to install other necessary components, such as the installation of electronic control components or the avoidance of wheels.

[0058] It should be noted that the upper cover 15 can be a single layer or a combination of multiple layers positioned above the first frame body 11. In this embodiment, the upper cover 15 includes a seat cushion 151 and an upper support plate 152, wherein the seat cushion 151 is positioned above the upper support plate 152. Accordingly, the assembly hole 13 is provided on the upper support plate 152, and an avoidance groove 1511 is provided on the seat cushion 151. The avoidance groove 1511 is used to avoid the assembly hole 13, thereby preventing the seat cushion 151 from interfering with the removal of the limit plate 14. Of course, in addition to the seat cushion 151 and the upper support plate 152, other panels may also be provided, and this is not limited here.

[0059] See Figure 5 and Figure 6 As shown, in other embodiments, two or more battery boxes 16 are provided on one side of the first frame body 11, wherein a gap is provided between the two battery boxes 16 for assembling the shock absorber 22 and the spring 21, and one end of the gap constitutes an assembly hole 13, and the limiting plate 14 can be detachably assembled at the assembly hole 13 of the first frame body 11.

[0060] Specifically, in order to improve the space utilization of the shock-absorbing frame, two or more battery boxes 16 are provided on one side of the first frame body 11, and a gap is provided between two adjacent battery boxes 16. The gap is used to assemble the shock absorber 22 and the spring 21. One end of the gap is opened to form an assembly hole 13, and the limiting plate 14 can be detachably assembled at the assembly hole 13 of the first frame body 11. Through the above structure, the gap between the battery boxes 16 is used to place the shock-absorbing assembly 2, which rationally utilizes the space resources inside the frame and avoids adding extra volume or weight to the vehicle. This compact design ensures the lightness and compactness of the wheelbarrow without affecting the layout and aesthetics of the overall structure. Correspondingly, the limiting plate 14 is provided at the assembly hole 13 formed by the gap between the two adjacent battery boxes 16, which can realize convenient maintenance and replacement of the shock-absorbing assembly 2 based on the compact wheelbarrow structure.

[0061] See Figure 5 and Figure 6 As shown, based on the structure in which the shock absorber 22 and the spring 21 are assembled between two adjacent battery boxes 16 , the limiting plate 14 is detachably installed on one or two battery boxes 16 adjacent to the limiting plate 14 .

[0062] Specifically, the limiting plate 14 can be connected to one of the adjacent battery boxes 16, or detachably connected to two adjacent battery boxes 16. When the limiting plate 14 is installed on one battery box 16, this installation method is convenient for production and removal, and is suitable for situations with high production efficiency requirements. When the limiting plate 14 is installed on two battery boxes 16, this installation method can provide greater stability and is suitable for situations with higher requirements for structural strength. This flexibility makes the design more adaptable to different usage scenarios and needs.

[0063] See Figure 5 and Figure 6 As shown, based on the structure in which the shock absorber 22 and the spring 21 are assembled between two adjacent battery boxes 16, the battery box 16 adjacent to the limit plate 14 is provided with an extension portion 161 toward the limit plate 14, and the limit plate 14 includes a limit portion 141 and a connecting portion 142. Both ends of the limit portion 141 are connected to the connecting portion 142. The limit portion 141 and the connecting portion 142 connected to its two ends are N-shaped, and the extension portion 161 and the connecting portion 142 are detachably connected, and the limit portion 141 is against the spring 21.

[0064] Specifically, in order to facilitate the detachable connection between the limiting plate 14 and the battery box 16, the battery adjacent to the limiting plate 14 is provided with an extension portion 161 in the direction of the limiting plate 14. The limiting plate 14 includes a limiting portion 141 and a connecting portion 142, wherein the connecting portion 142 and the extension portion 161 are used for the detachable connection between the limiting plate 14 and the battery box 16. The extension portion 161 and the connecting portion 142 can be provided with screw holes and connected by screws, or can be connected by a snap-fit structure. Of course, other detachable connection methods can also be used for connection. The n-shaped limiting plate 14 has a connecting portion 142 specifically connected to the extension portion 161. Compared with a plate-like structure with a smaller thickness, there is more space for connection with the extension portion 161. This not only increases the number of connection points, but also provides a larger contact area, thereby improving the stability after connection. In addition, the n-shaped limiting plate 14 design provides more connection space, making it easier to align and fix the connecting portion 142 and the extension portion 161 during assembly, reducing the difficulty of assembly.

[0065] See Figure 5 and Figure 6As shown, based on the structure in which the shock absorber 22 and the spring 21 are assembled between two adjacent battery boxes 16, the extension portion 161 is located on the outside of the battery box 16, the extension portion 161 is provided with a first connecting hole 1611, and the connecting portion 142 is provided with a second connecting hole 143 facing the side of the extension portion 161, and the extension portion 161 and the connecting portion 142 are connected by screws or bolts passing through the first connecting hole 1611 and the second connecting hole 143.

[0066] Specifically, the extension portion 161 is located on the outside of the battery box 16. The outside of the battery box 16 is the direction of the battery box 16 facing the outer surface of the shock absorber workshop. The extension portion 161 is arranged on the outside of the battery box 16. The user or maintenance personnel can directly act on the extension portion 161 without removing other components. The screws or bolts can be easily removed and installed through simple tools (such as a screwdriver), which greatly simplifies the maintenance and replacement process.

[0067] See Figure 4 and Figure 6 As shown, in some embodiments, in order to facilitate the adjustment of the damping adjustment assembly, the limit plate 14 is provided with an avoidance hole 144, and a damping adjustment assembly is provided in the shock absorber 22. The damping adjustment assembly has an adjustment knob 222, which can control the adjustment of the damping size of the damping adjustment assembly by rotating the adjustment knob 222. The adjustment knob 222 is set through the avoidance hole 144.

[0068] Specifically, by providing a clearance hole 144 on the limit plate 14, the adjustment knob 222 in the shock absorber 22 can pass through the clearance hole 144, allowing the user to adjust the damping force directly from the outside. This structure does not require the removal of the limit plate 14 or other components, greatly simplifying the adjustment process and improving user convenience.

[0069] See Figure 1 and Figure 2 As shown, in some embodiments, the first frame body 11 is a movable frame, the second frame body 12 is a fixed frame, the movable frame and the fixed frame are connected via a shock absorber 22 , and the assembly hole 13 is provided on the top of the first frame body 11 .

[0070] Specifically, the first frame body 11 is a movable frame, i.e., the first frame body 11 is the portion of the frame that participates in floating motion during normal driving, and primarily comprises components such as the battery box 16, the upper cover 15, and the electronic control unit. The second frame body 12 is a fixed frame, i.e., the second frame is the portion of the frame that remains relatively fixed during normal driving, and primarily comprises components such as the wheels and wheel mounts. During normal assembly, the first frame body 11, serving as the movable frame, is mounted on top of the shock-absorbing frame, and corresponding assembly holes 13 are provided on the top of the first frame body 11. Assembly and disassembly operations can be performed while the unicycle is in its normal upright position. This means that users or maintenance personnel do not need to flip or tilt the unicycle, and can perform maintenance work directly while the vehicle is upright, further simplifying the maintenance process and improving maintenance efficiency.

[0071] See Figure 1 and Figure 2 As shown, the utility model also provides a unicycle, comprising the above-mentioned shock-absorbing frame.

[0072] Specifically, the shock-absorbing frame is applied to a unicycle, and the other components of the unicycle are assembled on the shock-absorbing frame. During use, the detachable design of the limit plate 14 makes maintenance and replacement of the shock-absorbing assembly 2 (spring 21 and shock absorber 22) much simpler and faster. Users or maintenance personnel only need to remove the limit plate 14 to directly access the shock-absorbing assembly 2, without having to remove the entire upper cover 15 and the electronic control components thereon, greatly reducing the difficulty and time cost of maintenance.

[0073] 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.
