Description

Technical Field

[0001] This disclosure relates to the field of mobility scooter technology, and more particularly to a vibration damping structure for a mobility scooter and a mobility scooter. Background Technology

[0002] Currently, the front suspension systems of commuter bikes on the market typically occupy too much space and offer only minor shock absorption. For example, existing vertically mounted, counter-rotating shock absorbers take up considerable space, reducing foot space at the front of the bike. Existing single-link cantilever shock absorbers cause a change in track width when activated, leading to tire tilting, uneven tire wear, and difficulty steering. Furthermore, because the steering linkage is connected to the handlebars and fixed to the frame on one side and to the wheel hub on the other, shock absorption involves the handlebars rotating. However, the limited rotation angle of the steering linkage restricts the shock absorption range, resulting in ineffective damping. Utility Model Content

[0003] This disclosure provides a shock absorption structure for a mobility scooter and a mobility scooter in order to at least solve the above-mentioned technical problems existing in the prior art.

[0004] According to a first aspect of this disclosure, a shock absorption structure for a personal mobility vehicle is provided, comprising: a linkage damping mechanism including an elastic component and a linkage assembly, one end of the elastic component and one end of the linkage assembly being hinged to a vehicle frame; and a wheel hub mechanism, the other end of the elastic component and the other end of the linkage assembly being hinged to the wheel hub mechanism; wherein the linkage damping mechanism is located below the vehicle frame, and the linkage damping mechanism is used to absorb energy when the wheel hub mechanism vibrates.

[0005] In one embodiment, the linkage assembly includes a first link and a second link, one end of the first link being hinged to the vehicle frame and the other end of the first link being hinged to the wheel hub mechanism, one end of the second link being hinged to the vehicle frame and the other end of the second link being hinged to the wheel hub mechanism.

[0006] In one possible implementation, the connection points of the first link and the vehicle frame and the second link and the vehicle frame are not concurrent, and the connection points of the first link and the wheel hub mechanism and the second link and the wheel hub mechanism are not concurrent.

[0007] In one embodiment, the hub mechanism includes a front axle, with the other end of the first link and the other end of the second link hinged to the front axle.

[0008] In one embodiment, the elastic component includes a shock-absorbing spring, the two ends of which are respectively connected to the vehicle frame and the front axle.

[0009] In one possible implementation, the frame, the first link, the second link, and the elastic component form a four-bar linkage to enable the wheel hub mechanism to swing relative to the frame.

[0010] In one possible implementation, the connection point between the shock-absorbing spring and the front axle and the connection point between the second link and the front axle may be at the same point or not at the same point.

[0011] In one embodiment, the second link is arc-shaped.

[0012] In one embodiment, the number of the linkage damping mechanisms is two sets.

[0013] According to a second aspect of this disclosure, a mobility scooter is provided, the mobility scooter being provided with a vibration damping structure as described in any of the above-described embodiments.

[0014] In this disclosure, since the shock absorption structure of the mobility scooter includes a linkage shock absorption mechanism, which is hinged between the wheel hub mechanism and the frame, it can satisfy the up and down movement of the wheel hub mechanism without changing the wheel track, thus solving the problem of tire wear due to tire misalignment. At the same time, the elastic component can absorb energy and reduce vibration. Furthermore, since the linkage shock absorption mechanism is located below the frame, it reduces the space occupied by the footrest above the frame.

Other features of this disclosure will become readily apparent from the following description. Attached Figure Description

[0022] To make the objectives, features, and advantages of this disclosure more apparent and understandable, the technical solutions in the embodiments of this disclosure will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this disclosure, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this disclosure without creative effort are within the scope of protection of this disclosure.

[0023] The embodiments of this disclosure will now be described in detail with reference to the accompanying drawings.

[0024] Reference Figures 1-3 As shown, this disclosure discloses an exemplary embodiment of a shock absorption structure for a personal mobility vehicle, including a linkage damping mechanism 1 and a wheel hub mechanism 2. The linkage damping mechanism 1 includes an elastic component 11 and a connecting rod assembly 12. One end of the elastic component 11 and one end of the connecting rod assembly 12 are hinged to the vehicle frame 3, and the other end of the elastic component 11 and the other end of the connecting rod assembly 12 are hinged to the wheel hub mechanism 2. The linkage damping mechanism 1 is located below the vehicle frame 3 and is used to absorb energy when the wheel hub mechanism 2 vibrates.

[0025] In this embodiment, the shock absorption structure of the mobility scooter is mainly located below the front end of the frame 3. When the mobility scooter travels on bumpy roads, the linkage shock absorption mechanism 1 is subjected to impact forces from the road surface. These impact forces are transmitted through the elastic component 11 and the linkage assembly 12, where they are dispersed and absorbed. The elastic component 11 compresses along its axial direction, effectively absorbing and mitigating the impact force and improving the mobility scooter's stability. It is understood that in practical applications, the material hardness of the elastic component 11 is adaptively selected based on the desired shock absorption effect. The linkage assembly 12 contains at least two linkages. Since the mobility scooter's shock absorption structure includes the linkage shock absorption mechanism 1, which is hinged between the wheel hub mechanism 2 and the frame 3, it allows the wheel hub mechanism 2 to move up and down without changing the wheelbase, thus solving the problem of tire wear due to offset. Simultaneously, the elastic component 11 absorbs energy and reduces vibration. Furthermore, because the linkage shock absorption mechanism 1 is located below the frame 3, it reduces the space occupied by the footrest above the frame 3.

[0026] In one embodiment, the linkage assembly 12 includes a first linkage 121 and a second linkage 122. One end of the first linkage 121 is hinged to the vehicle frame 3, and the other end of the first linkage 121 is hinged to the wheel hub mechanism 2. One end of the second linkage 122 is hinged to the vehicle frame 3, and the other end of the second linkage 122 is hinged to the wheel hub mechanism 2.

[0027] Specifically, in one embodiment, the connection point between the first link 121 and the frame 3 and the connection point between the second link 122 and the frame 3 are not concurrent, and the connection point between the first link 121 and the wheel hub mechanism 2 and the connection point between the second link 122 and the wheel hub mechanism 2 are not concurrent.

[0028] In this embodiment, the linkage assembly 12 has two links, namely a first link 121 and a second link 122, both of which are hinged between the frame 3 and the wheel hub mechanism 2. The design of the first link 121 and the second link 122 requires ensuring that the elastic component 11 can be compressed along its own axial direction when the wheel hub mechanism 2 experiences upward bumps. Therefore, there must be a gap between the connection points of the first link 121 and the frame 3, and between the first link 121 and the wheel hub mechanism 2, to ensure that the first link 121, the second link 122, and the frame 3 do not form a fixed structure, allowing the wheel hub mechanism 2 to move up and down during bumps. The shapes of the first link 121 and the second link 122 can be the same or different, and both can be, but are not limited to, rectangular or arc-shaped.

[0029] In one embodiment, the hub mechanism 2 includes a front axle 21, with the other end of the first link 121 and the other end of the second link 122 hinged to the front axle 21.

[0030] In this embodiment, the hub mechanism 2 is the front wheel of the mobility scooter. The front axle 21 in the hub mechanism 2 is the structure that transmits the various forces between the frame 3 and the front wheel, as well as the bending moment and torque generated therefrom. The first link 121 and the second link 122 are both hinged to the front axle 21, and there is a gap between the hinge points of the two links and the front axle 21.

[0031] In one embodiment, the elastic component 11 includes a shock-absorbing spring, the two ends of which are respectively connected to the frame 3 and the front axle 21.

[0032] In this embodiment, shock-absorbing springs are used to absorb and reduce external vibrations and impacts to protect the stability and safety of the mobility scooter. The elasticity of the shock-absorbing spring is determined by the elastic properties of its material. When the mobility scooter is subjected to bumps and vibrations, the shock-absorbing spring is compressed or stretched, generating elastic force to counteract the external force, thereby reducing impact and vibration. Various types of shock-absorbing springs are available, including but not limited to compression springs, rubber springs, composite springs, or air springs, which can be selected according to actual needs.

[0033] It is understandable that the aforementioned frame 3, first link 121, second link 122 and elastic component 11 form a four-bar linkage so that the wheel hub mechanism 2 can swing relative to the frame 3.

[0034] In one embodiment, the connection point between the shock absorber spring and the front axle 21, and the connection point between the second link 122 and the front axle 21, may be concurrent or non-concurrent. Since the shock absorber spring can be compressed or stretched, the connection point between the shock absorber spring and the front axle 21 may be concurrent or non-concurrent with the adjacent link.

[0035] In one embodiment, the second link 122 is arc-shaped.

[0036] In this embodiment, the second link 122 is designed to be arc-shaped to avoid the front axle 21 and prevent the second link 122 from interfering with the front axle 21 during rotation, thus affecting normal operation.

[0037] In one embodiment, the number of linkage damping mechanisms 1 is two sets.

[0038] In this embodiment, the linkage damping mechanism 1 can be one or more sets. Preferably, there are two sets of linkage damping mechanisms 1, which are respectively set close to the two front wheels to work together to achieve the damping effect. It can be understood that when there is one set of linkage damping mechanisms 1, it can be set at the center of the wheel hub mechanism 2, which will not be elaborated further here.

[0039] This disclosure also provides a mobility scooter (not shown in the figures) equipped with a vibration damping structure as described in any of the above-described embodiments.

[0040] In this embodiment, by setting a shock-absorbing structure in the mobility scooter, the linkage shock-absorbing mechanism 1 is hinged between the wheel hub mechanism 2 and the frame 3, so that the wheel hub mechanism 2 can move up and down without changing the wheel track, thus solving the problem of tire wear due to tire offset. At the same time, the elastic component 11 can absorb energy, reduce vibration, and improve the stability and driving comfort of the mobility scooter. Furthermore, since the linkage shock-absorbing mechanism 1 is located below the frame 3, it reduces the space occupied by the footrest above the frame 3.

[0041] In the description of this disclosure, it should be understood that the orientation or positional relationship indicated by directional terms is usually based on the orientation or positional relationship shown in the accompanying drawings, and is only for the convenience of describing this disclosure and simplifying the description. Unless otherwise stated, these directional terms do not indicate or imply that the device or element referred to must have a specific orientation or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation on the scope of protection of this disclosure; the directional terms "inner" and "outer" refer to the inner and outer contours relative to the outline of each component itself.

[0042] For ease of description, spatial relative terms such as "above," "over," "on the upper surface of," and "above" are used herein to describe the spatial positional relationship between one or more components or features shown in the figures and other components or features. It should be understood that spatial relative terms include not only the orientation of the component as depicted in the figures but also different orientations during use or operation. For example, if the components in the figures are inverted as a whole, "above" or "above other components or features" will include cases where the component is "below" or "under" other components or features. Thus, the exemplary term "above" can include both "above" and "below." Furthermore, these components or features may also be positioned at other different angles (e.g., rotated 90 degrees or other angles), and this document intends to include all such cases.
