Description

Technical Field

[0001] This utility model relates to the field of shock absorption technology, and in particular to a shock absorption device with a simple structure and excellent shock absorption effect, and a scooter structure using the shock absorption device. Background Technology

[0002] It is known that most existing shock absorbers on the market use springs, pneumatic cylinders, or complex multi-link structures. While these traditional designs can provide shock absorption to some extent, they generally suffer from complex structures, numerous parts, and high manufacturing costs. After long-term use, these devices often experience a gradual decline in shock absorption performance due to wear and tear between parts, affecting not only the user experience but also making maintenance and replacement relatively cumbersome and inconvenient.

[0003] Furthermore, existing shock absorbers still have significant room for improvement in terms of structural integration, material durability, and lightweight design. In particular, current technology has not fully realized its potential in absorbing vibrations and optimizing shock absorption performance. This makes it difficult for existing devices to provide excellent shock absorption performance while maintaining structural simplicity. Some shock absorbers also fail to effectively absorb and cushion vibrations from various impacts, thus affecting comfort and safety.

[0004] Known scooter structures with shock absorption devices typically place the device between the frame and wheels to absorb vibrations transmitted from the road surface, improving riding comfort and stability. However, most existing scooter shock absorption devices are complex and bulky, making it difficult to achieve lightweight design and easy maintenance. Furthermore, some designs still fall short in terms of shock absorption and durability, failing to fully meet users' needs for excellent shock absorption and long-term reliability. Utility Model Content

[0005] The purpose of this utility model is to provide a shock absorption device that can effectively absorb vibrations, improve shock absorption performance, has a simple structure, and is durable and easy to maintain.

[0006] To achieve the above objectives, this utility model provides a shock-absorbing device, comprising a base having a first fixed portion for fixing, and a first through hole and a receiving hole located on one side of the first fixed portion; a first bolt group passing through the first through hole of the base; an elastic body having a spring-loaded portion receiving the receiving hole of the base, and a second through hole located within the spring-loaded portion; a second bolt group passing through the second through hole of the elastic body; and two swing arms located on both sides of the base; each swing arm having an arm portion located on one side of the base, a first arm hole that engages with the first bolt group, a second arm hole that engages with the second bolt group, and a swing joint portion for receiving vibration.

[0007] With the above configuration, when vibration is transmitted from the swing joint to the swing arm, the swing arm swings through the first bolt group and the mounting base, and the second bolt group is displaced, causing the elastic body to undergo elastic deformation at its elastic abutment within the receiving hole of the mounting base. This absorbs and buffers the vibration energy, thereby achieving an effective vibration damping effect. Therefore, it can effectively reduce transmitted vibration, improve the stability and durability of the overall structure, and has a simple structure that is easy to install and maintain.

[0008] Optionally, the first fixed part of the connector is provided with a first fixing hole for fixing. This effectively improves the stability and durability of the connection between the shock absorption device and other objects, avoids loosening or displacement caused by vibration, and further enhances the safety and reliability of the overall structure.

[0009] Optionally, the first bolt assembly includes a first bolt rod and a first bushing. The first bushing is disposed in the first through hole of the connector and has a first bushing hole. The first bolt rod passes through the first bushing hole of the first bushing. By providing the first bushing, friction between the first bolt rod and the connector can be isolated, extending the service life of the parts and improving structural stability.

[0010] Optionally, the first bolt assembly includes a first bolt rod and two first bushings. Each first bushing has a first bushing hole that passes through the first bolt rod, a first bushing portion that passes through the first arm hole of the swing arm, and a first bushing portion connected to the first bushing portion and located on one side of the arm portion of the swing arm. This configuration isolates the friction between the swing arm and the first bolt rod and other components, improving the durability of the shock absorber.

[0011] Optionally, the shock absorber further includes two bearings, each bearing having an outer ring and a bearing hole. The mounting base has two bearing mounting holes for mounting the outer ring of the bearing, and the first bolt assembly passes through the bearing's bearing hole. By providing the bearings, friction between the first bolt assembly and the mounting base can be isolated, improving the flexibility and durability of the shock absorber.

[0012] Optionally, the second bolt assembly includes a second bolt rod and a second bushing. The second bushing is disposed in the second through hole of the connector and has a second bushing hole. The second bolt rod passes through the second bushing hole of the second bushing. By providing the second bushing, friction between the second bolt rod and the elastomer can be isolated, extending the service life of the component and improving structural stability.

[0013] Optionally, the second bolt assembly includes a second bolt rod and two second bushings. Each second bushing has a second bushing hole that passes through the second bolt rod, a second bushing portion that passes through the second arm hole of the swing arm, and a second bushing portion connected to the second bushing portion and located on one side of the arm portion of the swing arm. Therefore, friction between the swing arm and the second bolt rod and other components can be isolated, improving the durability of the shock absorber.

[0014] Another objective of this invention is to provide a scooter structure that can quickly and securely integrate the shock absorption device, thereby improving the comfort and stability of the scooter while riding.

[0015] To achieve the aforementioned other objective, the present invention provides a scooter structure comprising a frame having a second fixed portion; and including a shock-absorbing device as described above, wherein the shock-absorbing device is connected and fixed to the second fixed portion of the frame via the first fixed portion of the mounting bracket; furthermore, the scooter structure also includes a wheel, which is mounted on the swing arm of the shock-absorbing device at the swing joint portion.

[0016] This invention improves the shock absorption performance and driving stability of the scooter by quickly and securely attaching the shock absorption device to the second fixed part of the vehicle body and by having the swing arm support the wheel through the swing joint.

[0017] Optionally, the shock absorber is provided with a first upper connection part, and the vehicle body is provided with a second upper connection part that connects to the first upper connection part; by connecting the first upper connection part and the second upper connection part, the bonding strength between the shock absorber and the vehicle body can be effectively improved, thereby enhancing structural stability and durability.

[0018] Optionally, the shock absorber has two first side joints, and the vehicle body has two second side joints for connecting with the two first side joints respectively; by connecting the first side joints with the corresponding second side joints, the fixing effect of the shock absorber on the vehicle body can be strengthened, preventing loosening or displacement caused by vibration.

[0079] First, it should be noted that the technical features provided by this utility model are not limited to the specific structures, uses, and applications described in the embodiments. The terminology used in the description is illustrative and descriptive language that can be understood by those skilled in the art. The directional terms such as "front," "upper," "lower," "rear," "left," "right," "top," "bottom," "inner," and "outer" mentioned in this specification are merely illustrative descriptive terms based on the normal usage direction and are not intended to limit the scope of protection of this utility model.

[0080] To illustrate the technical features of this utility model in detail, the following embodiments are provided in conjunction with the accompanying drawings.

[0081] like Figures 1 to 7 As shown, a preferred embodiment of the shock absorption device 1 provided by this utility model includes a base 10, two bearings 20, a first bolt group 30, an elastic body 40, a second bolt group 50, and two swing arms 60.

[0082] The connector 10 has a first fixed part 11, two first fixing holes 12, a first upper connecting part 13 and two first side connecting parts 14, a first through hole 15, two bearing mounting holes 16, a receiving hole 17 and a plurality of perforations 18. The first fixed part 11 is used to connect and fix with an object to be connected (such as a vehicle body, but not limited by this utility model) to ensure that the shock absorber 1 is stably installed; the first fixing holes 12 can be used to connect with the object to be connected; the first upper connecting part 13 and the first side connecting part 14 can be used to connect with the object to be connected more stably; the first through hole 15 is used for the first bolt group 30 to pass through; the bearing mounting holes 16 are provided on both sides of the first through hole 15 for installing bearings 20; the receiving hole 17 is used to assemble the elastomer 40, and the receiving hole 17 is inclined and its two ends are respectively semi-circular and flat; the perforations 18 can be arbitrarily distributed to reduce weight and provide heat dissipation.

[0083] The receiving hole 17 features an inclined design with a semi-circular end and a flat end, but this invention is not limited to this design. This structure helps the component to be securely positioned within the hole, preventing movement or loosening due to vibration. The semi-circular end provides a smooth contact surface, effectively dispersing stress and reducing localized damage, while the flat end provides stable support, ensuring the durability and stability of the overall structure. Furthermore, this hole design facilitates component assembly, improving manufacturing and maintenance convenience.

[0084] The bearing 20 includes an outer ring 21, a bearing hole 22, and two bearing edges 23. The outer ring 21 is installed in the bearing mounting hole 16 of the receiving seat 10 to ensure that the bearing 20 and the receiving seat 10 fit tightly and are not easily displaced; the bearing hole 22 is located inside the outer ring 21 and is used for the first bolt group 30 to pass through and connect, ensuring the fixation and smooth rotation between components, and improving the operating efficiency and durability of the shock absorption device 1; the bearing edges 23 are located at both ends and are responsible for fixing the internal structure of the bearing and bearing axial force to prevent the bearing 20 from shifting or falling off.

[0085] The first bolt assembly 30 is inserted into the first through hole 15 of the connector 10. The first bolt assembly 30 includes a first bolt rod 31, a first bolt head 32, a first bushing 33, and two first sleeves 34. The first bolt rod 31 is inserted into the bearing hole 22, the first bushing 33, and the two first sleeves 34 of the bearing 20. The first bolt head 32 is engaged with the first bolt rod 31 to fix the components of the first bolt assembly 30 and ensure the stability of the connection structure. The first bushing 33 is installed in the first through hole 15 of the connector 10 and has a first bushing hole 331 through which the first bolt rod 31 passes, which is used to isolate the friction between the first bolt rod 31 and the connector 10. The first pad 34 is respectively fitted onto both ends of the first bolt 31. The first pad 34 has a first sleeve hole 341, a first sleeve portion 342 and a first pad portion 343. The first sleeve hole 341 is fitted onto the first bolt 31. The first sleeve portion 342 passes through the rocker arm 60 and can isolate the friction between the first bolt 31 and the rocker arm 60. The first pad portion 343 is connected to the first sleeve portion 342 and is located between the bearing edge 23 of the bearing 20 and one side of the rocker arm 60, and can isolate the friction between the bearing 20 and the rocker arm 60.

[0086] The elastomer 40 has a spring-loaded abutment 41 and a second through hole 42. The spring-loaded abutment 41 is embedded in the receiving hole 17 of the connector 10 to ensure that the elastomer 40 can be stably positioned after assembly. The spring-loaded abutment 41 is inclined and its two ends are a semi-circular surface and a flat surface, respectively. The second through hole 42 is provided in the elastomer 40 for connection of the second bolt assembly 50, serving as a channel for the connection or fixing of various components of the device. In this embodiment, the elastomer 40 is made of polyurethane (PU), but the present invention is not limited to this. Other elastic materials with similar properties can also be used, such as thermoplastic polyurethane (TPU), polyether-type polyurethane elastomer, or polyester-type polyurethane elastomer, to meet different usage requirements and environmental conditions.

[0087] The spring-loaded portion 41 is inclined, with a semi-circular surface at one end and a flat surface at the other. However, this invention is not limited to this design. This design aims to optimize its fit and operation with the receiving hole 17. The inclined shape allows the spring-loaded portion 41 to undergo specific deformation and compression when subjected to shock, which helps to absorb impact energy more effectively. Its semi-circular end can fit tightly against the corresponding curved surface of the receiving hole 17, increasing the contact area to distribute pressure and reduce wear. The flat end provides stable force and support, ensuring that the spring-loaded portion 41 can accurately return to its original position or move within a specific range during shock absorption, thereby improving the efficiency and durability of shock absorption.

[0088] The second bolt assembly 50 includes a second bolt rod 51, a second bolt head 52, a second bushing 53, and two second bushings 54. The second bolt rod 51 passes through the second through hole 42 of the elastic body 40, and the second bolt head 52 is connected to the other end of the second bolt rod 51 to form a fixed structure. The second bushing 53 is installed in the second through hole 42 of the elastic body 40, and has a second bushing hole 531 through which the second bolt rod 51 passes, which can prevent the second bolt rod 51 from wearing against the elastic body 40 and expand the contact area with the elastic body 40. The second sleeve 54 is respectively fitted onto both ends of the second bolt 51, and has a second sleeve hole 541, a second sleeve portion 542 and a second pad portion 543; the second sleeve hole 541 is fitted onto the second bolt 51; the second sleeve portion 542 passes through the swing arm 60, which can isolate the friction between the swing arm 60 and the second bolt 51; the second pad portion 543 is connected to the second sleeve portion 542 and is located between the second bushing 53 and one side of the swing arm 60, which can isolate the friction between the second bushing 53 and the swing arm 60.

[0089] The swing arms 60 are located on both sides of the base 10. Each swing arm 60 includes an arm portion 61, a first arm hole 62, a second arm hole 63, and a swing joint portion 64. The arm portion 61 serves as a support structure, connecting and supporting the various functional components of the shock absorber. The arm portion is located on one side of the base. The first arm hole 62 is provided on the arm portion 61, accommodating the first sleeve portion 342 of the first sleeve pad 34, for connection and positioning with the first bolt assembly 30, ensuring that the swing arm 60 is securely installed in the device structure. The second arm hole 63 is used to connect with the second bolt assembly 50, accommodating the second sleeve portion 542 of the second sleeve pad 54, strengthening structural integration. The swing joint portion 64 is located at the other end of the arm portion 61, providing a fixed position for a vibration-damping component (such as an axle of a wheel, but not limited by this invention) to withstand vibration. The first pad 343 of the first sleeve 34 is placed against one side of the arm 61 to isolate it from friction with the bearing 20; the second pad 543 of the second sleeve 54 is placed against one side of the arm 61 to isolate it from friction with the second bushing 53. These designs clearly define the functions of each part of the swing arm 60, effectively improving the overall performance and durability of the shock absorption device 1.

[0090] When vibration is transmitted to the swing arm 60, the swing arm 60 pivots around the first bolt group 30 passing through the base 10, swinging on the base 10 and causing the second bolt group 50 passing through the elastic body 40 to displace, pulling the elastic abutment 41 of the elastic body 40 into the receiving hole 17 of the base 10 to produce elastic deformation. This elastic deformation effectively absorbs and buffers vibration energy, slowing down the vibration transmitted from the swing arm 60 to the base 10, thereby improving the shock absorption effect. The first bolt group 30 ensures that the swing arm 60 swings smoothly and is structurally durable; the second bolt group 50 passing through the elastic body 40 ensures that the elastic body 40 and the swing arm 60 are firmly connected, preventing the elastic body 40 from displacing or loosening. Through this structural configuration, the shock absorption device 1 achieves the swing arm 60 swinging around the first bolt group 30 during vibration, while simultaneously driving the second bolt group 50 to displace and pull the elastic body 40 to produce elastic recovery, thus absorbing vibration energy, effectively improving the overall shock absorption performance and durability, and maintaining a simple structure that is easy to maintain, achieving the purpose of this utility model.

[0091] By connecting the second bolt 51 to the second bushing 53, the second bushing 53 can abut against the elastic body 40 over a larger area, which can more effectively absorb vibration, improve shock absorption performance and comfort, and help achieve the purpose of this utility model.

[0092] In addition, the bearing 20 is mainly set in the bearing mounting hole 16 of the receiving seat 10. Its outer ring 21 is tightly fitted with the receiving seat 10 to support and guide the rotation of the first bolt group 30, reduce the friction and wear between rotating parts, and ensure that the shock absorption device 1 operates smoothly and is durable, which helps to achieve the purpose of this utility model.

[0093] The first bushing 33 of the first bolt assembly 30 is installed in the first through hole 15 of the connector 10, between the first bolt rod 31 and the connector 10, to isolate the friction between the two, distribute the load and extend the service life of the parts, and at the same time improve the stability and durability of the fastening parts, which helps to achieve the purpose of this utility model.

[0094] The first pad 34 of the first bolt group 30 and the second pad 54 of the second bolt group 50 can isolate friction between other components, maintain tightness and stability of the connection, and help achieve the purpose of this utility model.

[0095] like Figure 8 and Figure 9 As shown, a scooter structure 2 using the shock absorption device 1 of the above embodiment further includes a frame 70, two fixing bolt assemblies 80, and a wheel 90. The shock absorption device 1 is mounted on the frame 70 and positioned towards the rear of the frame to absorb vibrations from the wheel 90, improving the scooter's riding comfort and stability. This configuration allows the shock absorption device 1 to effectively buffer road impacts and, in conjunction with the wheel 90 and the frame 70, achieve overall structural stability and durability.

[0096] The vehicle body 70 is provided with a second fixed part 71, two second fixing holes (not shown in the figure), a second upper connecting part 73, and two second side connecting parts 74, which are used to install and fix the shock absorber 1. The second fixed part 71 ensures that the vehicle body 70 and the first fixed part 11 of the shock absorber 1 mounting base 10 can be firmly connected and fixed, improving the stability and safety of the overall structure, and effectively transmitting the vibration energy absorbed by the shock absorber 1, protecting the vehicle body structure and improving riding comfort. The second fixing holes correspond to the first fixing holes 12 of the shock absorber 1. The second upper connecting part 73 is connected to the second fixed part 71 and to the first upper connecting part 13 of the mounting base 10. The second side connecting parts 74 are connected to the second fixed part 71 and to the first side connecting part 14 of the mounting base 10. The connection between the second upper part 73 and the first upper part 13 of the connector 10 can be abutting or welding, etc. Abutting can provide positioning and make the connection stable, while welding can make the connection more stable; the connection between the second side part 74 and the first side part 14 of the connector 10 can be abutting or welding, etc. Abutting can provide positioning and make the connection stable, while welding can make the connection more stable.

[0097] The fixing bolt assembly 80 passes through the second fixing hole of the fixing body 70 and the first fixing hole 12 of the connector 10, so that the shock absorber 1 can be firmly fixed to the body 70, ensuring that the connection between the two is stable and not easy to loosen, further improving the strength and durability of the overall structure, while facilitating assembly and maintenance.

[0098] The wheel 90 includes an axle 91 and a wheel section 92. In this embodiment, it is a rear wheel, but it can also be a front wheel in other embodiments. The axle 91 is connected to the swing arm 60 at the swing joint 64, serving as the rotation center of the wheel 90, ensuring that the wheel 90 can rotate smoothly and withstand the impact force from the road surface. The wheel section 92 is the part in contact with the ground and is usually made of wear-resistant material to improve grip and durability. Suitable tire materials and tread patterns can be selected according to different road conditions to further enhance driving stability and safety.

[0099] By connecting the second fixed part 71 of the vehicle body 70 to the first fixed part 11 of the connector 10, the shock absorber 1 is ensured to be precisely and securely connected to the vehicle body 70, improving the structural connection and fixing strength, and facilitating assembly and maintenance. Thus, the second upper connecting part 73 connects to the first upper connecting part 13 of the connector 10, and the second side connecting part 74 connects to the first side connecting part 14 of the connector 10, making the connection between the connector 10 and the vehicle body 70 more stable. This design, combined with the resistance deformation of the swing arm 60 and the elastic body 40, effectively absorbs vibrations from the road surface, improving riding comfort and safety, while maintaining structural simplicity and ease of manufacturing and maintenance, achieving the purpose of this utility model.

[0100] In another embodiment, the scooter structure 2 may also be equipped with side covers and wheel covers (not shown), which respectively cover the corresponding parts of the shock absorption device and the wheels. The side covers are mainly used to protect the internal structure of the shock absorption device, prevent dust, mud and foreign objects from entering, and improve the durability and safety of the device. The wheel covers cover the outside of the wheels to prevent water splashes and foreign objects from getting stuck, and improve cleanliness and safety during riding.

[0101] In addition to the above examples, this utility model can be modified and improved in various ways to adapt to different design requirements and application environments, while still achieving the purpose of this utility model.

[0102] For example, the shock absorption device 1 can adjust the size ratio and material hardness of the elastomer 40 and the swing arm 60 according to different usage requirements to achieve different levels of shock absorption effect and durability, thereby further improving comfort and safety.

[0103] Alternatively, the shock absorber 1 can be combined with other shock absorber technologies, such as springs, air pressure or damping devices, to form a multi-stage shock absorber system to cope with more complex and varied vibration conditions, thereby expanding the application scope and performance of this utility model.

[0104] Alternatively, the elastomer 40 can be changed from a single elastomer shared by the integrated structure in the aforementioned embodiments to two independent elastomers, one on each side. This configuration can further improve the elastic adjustment range and shock absorption effect of the shock absorption device, and help to distribute the load, thereby improving structural stability and durability. Of course, the size, stiffness, and configuration of the elastomer 40 can still be flexibly adjusted according to shock absorption requirements to achieve optimal comfort and safety.

[0105] Finally, it must be reiterated that the constituent elements disclosed in the foregoing embodiments of this utility model are merely illustrative examples and are not intended to limit the scope of protection of this utility model. Any simple structural modifications or changes made without departing from the spirit of this utility model, or any substitutions with other equivalent elements, should still fall within the scope of the claims of this utility model.
