Technical Field

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

[0002] It is known that most scooter shock absorption devices on the market use spring, air pressure or multi-link structure. Although they can provide a certain shock absorption effect, the structure is relatively complex, the manufacturing cost is high, and the shock absorption performance is prone to decline due to wear and tear of parts during long-term use, making maintenance and replacement inconvenient.

[0003] In addition, existing shock absorbers still have room for improvement in terms of structural integration, durability and lightweighting. In particular, they have not fully utilized the application of impact mechanics, making it difficult to balance shock absorption performance with structural simplicity. Furthermore, some shock absorbers cannot effectively absorb vibrations from multiple directions on the road surface, affecting riding comfort and safety. Utility Model Content

[0004] The purpose of this invention is to provide a shock absorption device and its application in the structure of a scooter. It absorbs and buffers road vibrations through the deformation of specific components, thereby improving the shock absorption effect and riding comfort, while ensuring that the structure is simple and durable.

[0005] To achieve the above objectives, this utility model provides a shock-absorbing device, comprising a base having a vehicle body connection portion for connecting with a vehicle body and an anti-rotation mounting hole for mounting an elastic body; two elastic bodies, each having a base mounting portion for fitting with the anti-rotation mounting hole of the base, a through hole located in the center for pivoting, and a bearing portion for bearing; two swing arms, each having a bolt connection hole for pivoting the base and the elastic body, a shaft connection hole for connecting a wheel axle, and a swing abutment portion that abuts against the bearing portion of the elastic body; and a bolt assembly connecting the base, the elastic body, and the swing arms to form a compact device with bearing shock absorption function.

[0006] This invention utilizes the abutting connection between the elastic body and the swing arm's supporting and swinging parts to cause the elastic body to deform under the force of the vehicle body, thereby absorbing and buffering vibrations from the road surface, improving shock absorption and riding comfort; at the same time, the bolt connection between the connector and the elastic body and the swing arm ensures structural stability and ease of assembly and maintenance.

[0007] Preferably, the abutment part of the elastomer is a protruding structure, and the abutment part of the swing arm is a recessed structure; through the cooperation of the protrusion and the recess, the contact between the elastomer and the swing arm is more stable, thereby improving the structural strength and abutment transmission efficiency of the shock absorber.

[0008] Preferably, the abutment part of the elastomer has a recessed structure, and the abutment part of the swing arm has a protruding structure; through the complementary design of the recessed and protruding parts, the contact between the elastomer and the swing arm is ensured to be precise and durable, thereby enhancing the stability of the shock absorption effect.

[0009] Preferably, the bearing portion of the elastomer is designed with a gradually rising and falling shape in the circumferential direction; through this gradual shape, the elastomer can generate a progressive damping effect during the bearing process, effectively improving shock absorption performance and service life.

[0010] Preferably, the swing arm's abutment portion is designed with a gradually rising and falling shape in the circumference; this shape design makes the contact between the swing arm and the elastic body more compact and elastic, promoting smooth abutment and vibration absorption of the shock absorption device.

[0011] Preferably, the receiving seat is provided with two bearing mounting holes for mounting the outer ring of the bearing, and the bolt group passes through the bearing; by setting the bearing, the friction between the receiving seat and the elastic body and the swing arm is reduced, and the smoothness and durability of the shock absorption device are improved.

[0012] To achieve the above objectives, this utility model provides a scooter structure using the aforementioned shock-absorbing device. The scooter structure includes a frame with a mounting base, and the shock-absorbing device is mounted on the mounting base. The swing arm of the shock-absorbing device has a wheel mounting portion, and a wheel is mounted on the wheel mounting portion, forming a scooter with a stable structure and excellent shock absorption effect.

[0013] This invention integrates a shock-absorbing device into the joint of the scooter frame, utilizing the deformation between the elastic body and the swing arm to absorb road vibrations, thereby improving the riding comfort and safety of the scooter. It also features a simple structure that is easy to manufacture and maintain.

[0014] Preferably, the scooter structure also includes a wheel cover that is attached to the vehicle body and covers the wheels; the wheel cover can effectively prevent dust and foreign objects from entering the wheels and shock absorption devices, thereby improving the overall durability and safety of the structure.

[0015] Preferably, the scooter structure also includes side covers covering the swing arms with shock absorption devices; the side covers protect the swing arms from external impacts and dirt, and enhance the integrity and aesthetics of the scooter's appearance.

[0016] Preferably, the shock absorber can be set facing forward or backward; by adjusting the setting direction of the shock absorber, it can adapt to different usage needs and road conditions, thereby improving the scooter's flexibility and shock absorption effect. Attached Figure Description

[0070] The applicant first clarifies that in the embodiments and accompanying drawings described below, the same reference numerals denote the same or similar elements or their structural features. It should be noted that the elements and structures in the drawings are for illustrative purposes and are not drawn to scale or in quantity; features of different embodiments may be used interchangeably if feasible in practice. Secondly, when it is stated that an element is disposed on another element, it means that the aforementioned element is directly disposed on the other element, or indirectly disposed on the other element; that is, one or more other elements are disposed between the two elements. Conversely, when it is stated that an element is "directly" disposed on another element, it means that no other elements are disposed between the two elements.

[0071] To illustrate the technical features of this utility model in detail, the following embodiments are provided and described in conjunction with the accompanying drawings, wherein:

[0072] like Figures 1 to 6 As shown, the shock absorption device 1 provided in the first embodiment of this utility model includes a base 10, two bearings 20, two elastic bodies 30, a bolt group 40, and two swing arms 50.

[0073] The connector 10 is provided with a receiving part 11 for connecting to the scooter body to ensure that the shock absorption device is securely installed; two anti-rotation mounting holes 13 are located on both sides of the connector 10 for mounting the connector mounting part 31 of the elastomer 30 to ensure that the elastomer 30 can be stably fixed and has appropriate rotation space; two bearing mounting holes 15 are provided on both sides of the connector 10 for installing bearings 20 to reduce friction between rotating parts and improve the smoothness and durability of the device operation.

[0074] The bearing 20 includes an outer ring 21 and a central shaft hole 23. The outer ring 21 is installed in the bearing mounting hole 15 of the connector 10 to ensure that the bearing 20 and the connector 10 fit tightly and are not easily displaced; the shaft hole 23 is located at the center of the outer ring 21, providing a channel for the bolt assembly 40 to pass through, ensuring the fixation and rotation of each connecting component.

[0075] The elastomer 30 has a mounting portion 31, a through hole 33, and multiple abutment portions 35. The mounting portion 31 is square and designed to be fitted into the anti-rotation mounting hole 13 of the mounting base 10, ensuring that the elastomer 30 can be stably positioned and prevented from rotating after assembly. The through hole 33 is located in the center of the elastomer 30, through which the pivot bolt or bolt assembly 40 passes, serving as a pivot or fixing channel for various components of the device. The multiple abutment portions 35 are recessed structures formed on the outer periphery of the elastomer 30, specifically for the abutment portion 55 of the swing arm 50 to engage, providing effective positioning and abutment area when under force, and can be designed with different depths or shapes to adjust the deformation stroke and shock absorption characteristics of the elastomer. This structural design helps to improve the stability and durability of the shock absorption device and enhance its effect of absorbing and buffering vibrations.

[0076] The elastomer 30 can be made of various rubber materials, such as natural rubber (NR), nitrile rubber (NBR), neoprene rubber (CR), silicone (SI), or polyurethane rubber (PU). These rubber materials possess excellent elasticity, resilience, and abrasion resistance, effectively absorbing and cushioning vibrations from the road surface, thus improving shock absorption performance and riding comfort. Furthermore, the flexibility and fatigue resistance of rubber materials help extend the service life of the shock absorption device while reducing overall weight, promoting lightweight design for scooters.

[0077] The bolt assembly 40 passes through the shaft hole 23 of the bearing 20 and the through hole 33 of the elastic body 30.

[0078] The swing arm 50 includes a swing arm body 51, a bearing connector 53, a swing abutment 55, a bolt hole 57, and a shaft connection hole 59. The swing arm body 51 serves as the main structure, connecting and supporting the various functional components. The bearing connector 53, located on the swing arm body 51, supports and fixes the bearing 20, ensuring stable bearing position during operation, effectively reducing friction and wear between rotating components, and improving the smoothness and durability of the shock absorber. The swing abutment 55 is a latching structure located at one end of the swing arm body 51, specifically designed to cooperate with the abutment portion 35 of the elastic body 30, generating a resisting deformation when the swing arm is under force, achieving vibration absorption and buffering effects. The bolt hole 57, located on the swing arm body 51, is used for connection and positioning with the bolt assembly 40, ensuring the swing arm 50 is securely installed in the device structure. The shaft connection hole 59, located at the other end of the swing arm body 51, is for mounting the wheel axle, allowing the wheel to rotate smoothly and withstand impacts from the road surface. This design ensures that the functions of each part of the swing arm 50 are clearly defined and work together, effectively improving the overall performance and durability of the shock absorption device.

[0079] The assembly method of this embodiment is as follows: First, install the two bearings 20 into the bearing mounting holes 15 of the connector 10, ensuring that the outer ring 21 of the bearing fits tightly with the bearing mounting hole 15; then, insert the connector mounting parts 31 of the two elastic bodies 30 into the anti-rotation mounting holes 13 of the connector 10, and align the through holes 33 with the bearing shaft holes 23; next, sleeve the two rocker arms 50 onto the bolt assembly 40, and make the bolt connection holes 57 of the rocker arms 50 abut against the receiving parts 35 of the elastic bodies 30; finally, pass the bolt assembly 40 through the shaft holes 23 of the bearings 20 and the through holes 33 of the elastic bodies 30 to complete the connection and fixation of the overall structure. This assembly process is simple and the structure is compact, which is conducive to production and maintenance.

[0080] The working mechanism of this embodiment is as follows: When the scooter is in motion, road vibrations are transmitted to the swing arm 50 through the wheels. The swing arm 50 abuts against the abutment portion 55 of the elastic body 30, driving the elastic body 30 to deform under the abutment, thereby absorbing and buffering the vibration energy. The bearing 20 reduces friction between the components, making the abutment action smoother and more durable. This design not only improves the shock absorption effect but also ensures structural stability and durability, enhancing riding comfort and safety.

[0081] Through the above structural design and assembly method, this embodiment can effectively utilize the deformation between the elastomer and the swing arm to absorb road vibration, thereby improving shock absorption performance and riding comfort. At the same time, the bearing configuration reduces friction, ensuring smooth operation and durability of the device. The overall structure is simple and easy to manufacture and maintain, achieving the purpose of this utility model to provide a compact, high-performance and cost-effective shock absorption device and its application in scooter structures.

[0082] like Figures 7 to 12 The image shows a second embodiment of the shock-absorbing device provided by this utility model, which is largely the same as the one described above, also including a base 10, two bearings 20, two elastic bodies 30, a bolt assembly 40, and two swing arms 50. The main differences are: the shape and structure of the bearing portion 35 of the elastic body 30 are slightly different, and the shape and structure of the swing abutment portion 55 of the swing arm 50 are slightly different. The bearing portion 35 of the elastic body 30 adopts a circumferentially deepening and shallowing design, and the swing abutment portion 55 of the swing arm 50 has a rounded head design.

[0083] With this structural design, the swing arm 50's abutment portion 55 can smoothly engage with the elastic body 30's support portion 35, and generate a stable engagement and support effect during assembly and stress application. Its engagement effect is the same as that provided by the first embodiment of the shock absorption device, which can effectively absorb and buffer vibrations from the road surface, ensuring shock absorption performance and structural stability, and thus achieving the purpose of this utility model to improve the riding comfort and safety of the scooter.

[0084] In addition, the bearing portion 35 of the elastomer 30 adopts a circumferentially deepening and shallowing design. This design not only allows the elastomer to gradually adjust the bearing resistance when deformed by bearing, but also produces different degrees of compression deformation when subjected to axial pressure, providing additional buffering effect, further extending the shock absorption stroke and improving shock absorption performance and durability, thus achieving the purpose of this utility model.

[0085] like Figures 13 to 18 As shown, the scooter structure 2 using the shock absorption device 1 of the first embodiment further includes a body 60, two wheels 70, two side covers 80, and two wheel covers 90. One shock absorption device 1 is arranged in a forward direction, and the other shock absorption device 1 is arranged in a rearward direction.

[0086] The vehicle body 60 is provided with two mounting brackets 61 and two cover portions 65, with each mounting bracket 61 having a slit 63. The mounting brackets 61 are used to install and fix the shock absorber 1, ensuring a stable connection between the shock absorber and the vehicle body 60, thereby improving the stability and safety of the overall structure. The slit 63 is designed on the mounting brackets 61 to provide the necessary elastic space for the installation of the shock absorber, allowing it to have a moderate range of motion when deformed under stress, preventing the shock absorber from being affected by excessive tightness, and also facilitating future maintenance or replacement of parts.

[0087] The wheel 70 has an axle 71 and a wheel section 73. The axle 71 passes through the shaft hole of the swing arm 50 and serves as the rotation center of the wheel 70, ensuring that the wheel can rotate smoothly and withstand the impact force from the road surface. The wheel section 73 is the part that contacts the ground and is usually made of wear-resistant material to improve grip and durability. Suitable tire materials and tread designs can be selected according to different road conditions.

[0088] The side cover 80 has a connecting arm portion 81 and a cover portion 83. The connecting arm portion 81 is designed to fit tightly with the swing arm 50, ensuring that the side cover 80 is securely installed on the outside of the shock absorber and can move accordingly with the swing arm 50. The cover portion 83 covers the outside of the wheel 70, forming a protective barrier that effectively prevents dust, sand, and other foreign objects from entering the wheel and shock absorber area, improving structural durability and safety.

[0089] The wheel cover 90 has a body connection portion 91 and a cover portion 93. The body connection portion 91 is located at one end of the wheel cover 90 and is used to precisely connect with the cover portion 65 of the body 60, ensuring that the wheel cover 90 is firmly fixed to the body. The cover portion 93 extends and covers the outer perimeter of the wheel 70, further enhancing the protective effect and preventing water and mud from splashing into the wheel and shock absorber. The shape and coverage area of ​​the cover portion 93 can be adjusted according to the wheel size to balance practicality and aesthetics.

[0090] The design of the mounting bracket 61 allows the shock absorber 1 to be precisely and securely installed on the vehicle body 60, ensuring the structural strength of the connection between the shock absorber and the vehicle body, and facilitating subsequent assembly and maintenance. The slot 63 provides the necessary installation space for the shock absorber 1 under stress, avoiding interference during assembly, and also helps absorb minor deformations between the vehicle body and the shock absorber, improving the overall structural durability and adaptability.

[0091] The wheel cover 90 is securely fixed to the vehicle body 60 by the cover part 65, forming a complete protective structure with the side cover 80, preventing damage or malfunction of the wheel area due to the intrusion of foreign objects. The coordinated configuration of the side cover 80 and the wheel cover 90 can not only effectively block dust, water droplets and gravel from entering the shock absorption device and wheel area, extending the service life of key components, but also improve the overall safety and durability of the scooter.

[0092] Furthermore, the design of the arm portion 81 and cover portion 83 of the side cover 80 allows for a tight fit with the swing arm 50, further enhancing the protective effect, reducing maintenance frequency, and lowering maintenance costs. The cover portion 93 of the wheel cover 90 can be adjusted according to the wheel size and structure to ensure both aesthetic appeal and practicality, while also improving the overall quality of the scooter.

[0093] By integrating the shock absorption device 1 into the mounting joint 61 of the scooter body 60, and cooperating with the swing arm 50 and the deformation of the elastic body, it can effectively absorb vibrations from multiple directions of the road surface, improve riding comfort and safety, and at the same time, the structure is simple and easy to manufacture and maintain.

[0094] The shock absorption device 1 of the second embodiment can also be applied to the scooter structure 2. Its composition and operation are basically the same as those of the first embodiment, including main components such as a mounting base, bearing, elastomer, bolt assembly, and swing arm. The only difference lies in the local structural design of the elastomer and swing arm. This structure can also effectively absorb and buffer vibrations from the road surface, improving the riding comfort and durability of the scooter. It also has the advantages of compact structure, convenient installation, and easy maintenance, and is suitable for various types of scooter products.

[0095] 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:

[0096] For example, the shock absorption device of this utility model can be adjusted according to different vehicle body structures or usage requirements, such as the size ratio of the elastomer and the swing arm, the material hardness, and the shape design of the bearing part and the swing arm, to achieve different degrees of shock absorption effect and durability, and further improve the riding comfort and safety of the scooter.

[0097] Alternatively, it can be combined with other shock absorption technologies such as springs, air pressure or damping devices to work in synergy with this shock absorption device to form a multi-stage shock absorption system, in order to cope with more complex and varied road conditions and expand the application scope and performance of this utility model.

[0098] Alternatively, the elastomer 30 can be configured on both sides of the shock absorption device. Besides having one elastomer 30 on each side as in the aforementioned embodiment, a single elastomer 30 can be used, sharing an integrated structure on both sides, to simplify the device structure and reduce costs. Furthermore, the configuration of the elastomer 30 is not limited to both sides; it can also be configured on one side, flexibly adjusted according to the scooter's body structure and shock absorption requirements. A single-side configuration can reduce the device's weight and simplify the manufacturing process, but shock absorption performance and overall structural stability must be considered to ensure both shock absorption effectiveness and safety of use.

[0099] Finally, it must be reiterated that the methods and constituent elements disclosed in the foregoing embodiments of this utility model are merely illustrative examples and are not intended to limit the patent scope of this utility model. Any simplified structural modifications or changes made based on the scope of protection of this utility model and the contents of the utility model specification, or any substitutions with other equivalent elements, should still fall within the scope of the patent application of this utility model.
