Description

Technical Field

[0001] This utility model relates to the field of vehicles, and in particular to a vehicle with vibration reduction function. Background Technology

[0002] Scooters are a type of transportation tool, and as people's living standards and quality of life improve, their demands for transportation tools also increase. Currently, the common way to ride a scooter is to hold the handlebars with both hands to control the direction, and place your feet on the scooter's footrests to propel it forward. A scooter includes a footrest, a pole located at the front of the footrest, and front and rear wheels located at the bottom of the footrest.

[0003] In current scooter technology, vibration damping between the wheels and pedals is generally achieved using springs, rubber shock absorbers, or hydraulic damping systems. However, the wheels need to maintain a sliding connection with the frame to accommodate movement demands, and the damping components often need to be separately mounted between the pedals and the wheel frame. This separate design complicates the installation process of the frame and wheels.

[0004] Therefore, it is necessary to propose a new technical solution to overcome the shortcomings of existing technologies. Utility Model Content

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

When a component is said to be "set on" another component, it can be directly set on the other component or it may be set to a component in between.

[0046] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0047] like Figures 1 to 4 As shown, this application provides a vehicle 100 with vibration damping function, including a frame 10 and a wheel 20 disposed on the frame 10 via a wheel frame 21; one of the frame 10 and the wheel frame 21 has a first mounting portion 11, and the other has a second mounting portion 22 sleeved on the outside of the first mounting portion 11; the vehicle 100 further includes a vibration damping member 30, which is disposed between the first mounting portion 11 and the second mounting portion 22; wherein, the vibration damping member 30 is configured to isolate the first mounting portion 11 and the second mounting portion 22, so as to buffer the vibration between the wheel 20 and the frame 10.

[0048] The frame 10 and the wheel frame 21 are respectively provided with a first mounting part 11 and a second mounting part 22. The second mounting part 22 is axially sleeved on the outside of the first mounting part 11 and the vibration damping member 30, and the vibration damping member 30 is disposed between the first mounting part 11 and the second mounting part 22, so as to realize the assembly of the frame 10, the wheel frame 21 and the wheel 20.

[0049] The vibration damping component 30 isolates the first mounting part 11 and the second mounting part 22, realizing direct isolation and buffering of the vibration between the wheel 20 and the frame 10. This ensures that the vibration of the wheel 20 is directly transmitted and buffered through the vibration damping component 30, effectively simplifying the complex process of additional assembly required by traditional separate vibration damping devices and solving the problem of complicated installation of the frame 10 and the wheel 20 in the prior art.

[0050] In this embodiment, as Figure 1As shown, the vehicle 100 is a mobile tool used for transporting or carrying people / goods; for example, the vehicle 100 is a scooter. The frame 10 is the scooter's footboard; the frame 10 has opposing front and rear sides, and the frame 10 has a footrest area 12. The footrest area 12 is located at the top of the frame 10 for the user to step on.

[0051] In this embodiment, as Figure 1 As shown, the vehicle 100 has a height direction (e.g., Figure 1 (in the X direction), width direction (e.g.) Figure 1 (in the Y direction) and the length direction (e.g.) Figure 1 (Z direction in the text). It should be noted that the length direction of the vehicle 100 is the direction from the front side of the frame 10 to the rear side of the pedal; on the same horizontal plane, the width direction of the vehicle 100 is perpendicular to the length direction of the vehicle 100; the height direction of the vehicle 100 is approximately the same as the vertical direction.

[0052] In this embodiment, as Figure 1 As shown, the vehicle 100 also includes a front wheel 23, a rear wheel 24, a vertical pole 40, and a handlebar. The front wheel 23 is disposed on the front side of the frame 10; the rear wheel 24 is disposed on the rear side of the frame 10; the vertical pole 40 is disposed on the front side of the frame 10; and the handlebar is disposed on the end of the vertical pole 40 facing away from the frame 10. At least one of the front wheel 23 and the rear wheel 24 is the wheel 20 in the above embodiment. Preferably, the rear wheel 24 is the wheel 20 in the above embodiment.

[0053] In this embodiment, as Figure 1 As shown, of both the front wheel 23 and the rear wheel 24, at least one is a drive wheel, and at least one can provide braking function. For example, the vehicle 100 uses front wheel 23 for drive and rear wheel 24 for disc brakes; front wheel 23 drive allows for easy control and climbing while riding, and rear wheel 24 disc brakes can prevent rollover during sudden braking, thus improving the driving safety of the vehicle 100. Both front wheel 23 drive and rear wheel 24 disc brakes can utilize existing technologies, which will not be further elaborated here. For example, the front wheel 23 may have a motor; for example, a hub motor or a mid-mounted motor can be used.

[0054] In this embodiment, as Figure 1As shown, the upright 40 can be fixedly or pivotally connected to the front side of the frame 10; the end of the upright 40 connected to the frame 10 is the bottom end, and the end connected to the handlebar is the top end. The upright 40 can be straight or partially curved depending on the spatial orientation; the upright 40 can be hollow or solid. When the upright 40 is hollow, weight can be reduced or internal cables can be installed. The upright 40 also includes a decorative shell 41, located on the outside of the upright 40. The upright 40 has a certain angle or is inclined with respect to the vertical direction; when the upright 40 is inclined with respect to the vertical direction, the upright 40 is inclined towards the pedal direction. The connection method between the upright 40 and the frame 10 can use existing technology, which will not be further elaborated here.

[0055] In this embodiment, as Figure 1 As shown, the handle is for the user's hands to grip. The handle includes two grips, which are located on either side of the upright 40. The surface of the grips is typically treated with an anti-slip texture or soft rubber coating to further enhance grip comfort and anti-slip performance.

[0056] In this embodiment, as Figures 2 to 4 As shown, both the first mounting part 11 and the second mounting part 22 extend along the rotation axis of the wheel 20, so that the first mounting part 11 and the second mounting part 22 can bear radial loads. The radial constraint characteristics of the mechanical structure effectively avoid the risk of axial movement or disengagement of the first mounting part 11, the second mounting part 22 and the vibration damping member 30.

[0057] In this embodiment, as Figures 2 to 4 As shown, the first mounting part 11 includes a first mounting shaft 111 and a second mounting shaft 112 spaced apart; the second mounting part 22 is a sleeve structure. The first mounting shaft 111 and the second mounting shaft 112 are respectively inserted into the axial ends of the sleeve structure to form a nested fit structure. When the first mounting part 11 is disposed on the frame 10 and the second mounting part 22 is disposed on the wheel 20, the end of the first mounting shaft 111 facing away from the second mounting shaft 112 is fixed to the frame 10, and the end of the second mounting shaft 112 facing away from the first mounting shaft 111 is fixed to the frame 10. After the first mounting shaft 111 and the second mounting shaft 112 are respectively inserted into the axial ends of the sleeve structure, the first mounting shaft 111 and the second mounting shaft 112 are fixed to the frame 10 by bolts or welding to form a stable structure.

[0058] In this embodiment, as Figures 2 to 4 As shown, the wheel frame 21 also includes two connecting frames 211, which are located on both sides of the wheel 20. The connecting frames 211 are rotatably connected to the wheel 20 and are fixedly connected to the second mounting part 22. The two connecting frames 211 are spaced apart along the axial direction of the second mounting part 22 and are fixedly connected to the second mounting part 22 by welding or bolts.

[0059] In this embodiment, as Figures 2 to 4 As shown, the vibration damping component 30 has a cylindrical structure and is fitted onto the outside of the first mounting part 11. The vibration damping component 30 achieves omnidirectional and uniform absorption of the vibration of the wheel 20 through a 360° annular buffer surface. The vibration damping component 30 and the first mounting part 11 have an interference fit; the vibration damping component 30 and the second mounting part 22 also have an interference fit; this ensures the positioning stability of the vibration damping component 30 in a vibration environment and avoids the vibration transmission attenuation or abnormal noise problems caused by gaps in traditional loose-fit structures. At the same time, the interference fit eliminates the need for additional fasteners, simplifies the assembly process, and reduces production costs. Its self-tightening characteristics also enhance the durability of the structure, effectively solving the problems of loosening, displacement, and vibration damping performance degradation caused by long-term use of traditional vibration damping devices, achieving a dual breakthrough in structural compactness and vibration damping performance.

[0060] In this embodiment, as Figures 1 to 2 As shown, the vibration damping component 30 is made of silicone or rubber. There are at least two vibration damping components 30; these at least two components are spaced apart along the axial direction of the first mounting portion 11, reducing the contact area between the vibration damping component 30 and the frame 10 and wheel frame 21, thereby significantly reducing the vibration transmission efficiency between the two components and thus reducing vibration transmission between the frame 10 and wheel frame 21. The two vibration damping components 30 are respectively fitted onto the outer sides of the first mounting shaft 111 and the second mounting shaft 112.

[0061] The technical features of the above embodiments can be combined arbitrarily. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as the combination of these technical features does not contradict each other, it should be considered to be within the scope of this specification. When technical features of different embodiments are embodied in the same drawing, it can be regarded as the drawing also disclosing examples of combinations of the various embodiments involved.

[0062] The above embodiments only illustrate several implementation methods of this utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make several modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model.
