Description

Technical Field

[0001] The utility model belongs to the technical field of adjustable shock absorbers, and in particular relates to an adjustable shock absorbing mechanism and an electric unicycle balancing vehicle. Background Art

[0002] When a unicycle is driving on the road, the unevenness of the road surface affects the driver's comfort and may even affect safety. Therefore, a shock absorber is usually installed at the connection between the body and the wheel. However, the current shock absorber is generally fixedly installed on the unicycle, resulting in a single shock absorber hardness. Obviously, the same unicycle is difficult to meet the shock absorption requirements of different road conditions (such as flat roads and mountain roads), which is also prone to damage to the unicycle. Moreover, even on the same road conditions, different riders have different ideal riding experience requirements.

[0003] Based on this situation, the currently more representative shock-absorbing structure, such as the compact nonlinear shock-absorbing structure disclosed in the existing patent technology 201922202208.0, includes a first component and a second component, and the first component and the second component can move parallel to each other so as to move closer to or away from each other, and a shock-absorbing assembly is provided on the same side of the first component and the second component; by arranging the shock-absorbing assembly on the same side of the first component and the second component, the space of the first component and the second component in the direction of the shock-absorbing stroke will not be occupied, thereby facilitating the installation of the elastic element.

[0004] The above solution shows a telescopic shock-absorbing structure for unicycle use, but the shock-absorbing effect cannot be adjusted.

[0005] Another example is the electric scooter shock-absorbing structure and electric scooter disclosed in the existing patent technology 202221750583, which include a support, a left cantilever, a right cantilever and a shock absorber; the support has a hinge portion and a first shock absorber mounting portion located above the hinge portion; a second shock absorber mounting portion is provided between one end and the other end of the left cantilever and the right cantilever; one of the first shock absorber mounting portion and the second shock absorber mounting portion is fixedly connected to the shock absorber, and the other includes a slide groove, and one end of the shock absorber extends into the slide groove through a connecting shaft and can selectively slide along the slide groove to change its position, and the current position of the connecting shaft is fixed by a locking member. In addition, the existing patent technology 202322043309.6 discloses a shock-absorbing structure and a scooter, including a base, a rocker arm and a shock-absorbing assembly, the base having a first connecting portion and a first mounting portion; one end of the rocker arm is used to connect to the axle of the wheel, and the other end is rotatably connected to the first connecting portion, and a second mounting portion is provided on the rocker arm; the shock-absorbing assembly includes an adjusting rod and a shock absorber that are rotatably connected to each other, the adjusting rod is rotatably connected to one of the first mounting portion and the second mounting portion, and the shock absorber is rotatably connected to the other of the first mounting portion and the second mounting portion; the adjusting rod is configured to rotate relative to the rocker arm, and the current position of the adjusting rod can be detachably fixed.

[0006] However, the above two solutions only show adjustable shock absorption solutions for scooters. Although there are adjustable mechanisms, they can only be adjusted through tools. The adjustment process is very time-consuming and the operation is relatively troublesome for ordinary users. Utility Model Content

[0043] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0044] Please refer to Figure 1-Figure 3 One embodiment of the present invention provides an adjustable shock absorbing mechanism, comprising: a shock absorber 10, an adjusting device 20, and a frame 30, wherein one end of the shock absorber 10 is rotatably connected to a first connecting member 31 of the frame 30, and the other end is fixedly connected to a second connecting member 32 of the frame 30 via the adjusting device 20; the adjusting device 20 includes a third connecting member 21 and a locking assembly, wherein a fixed end of the third connecting member 21 is hingedly connected to the second connecting member 32, a free end of the third connecting member 21 is hingedly connected to the other end of the shock absorber 10, and the third connecting member 21 is fixedly connected to the second connecting member 32 via the locking assembly;

[0045] The locking assembly is configured to be able to adjust the fixed position of the free end of the third connecting member 21 , thereby changing the working stroke of the shock absorber 10 .

[0046] In this embodiment, when it is necessary to adjust the elastic force of the shock absorber 10, it is only necessary to manually unlock the locking assembly, retract the adjustment slider 23, release the fixed connection structure between the bite adjustment slider 23 and the second connecting member 32, adjust the fixed position of the free end of the third connecting member 21 to the required position, and then lock the adjustment slider 23 again through the adjustment lock 22. It is easy to operate, stable and reliable to use, and does not require the use of additional tools.

[0047] In one embodiment, the frame 30 includes a top bracket 33 and a telescopic guide rod 34 connected to each other, and the top bracket 33 is slidably connected relative to the fixed side of the telescopic guide rod 34; the first connecting member 31 is hinged to the top bracket 33, and the second connecting member 32 is hinged to the telescopic guide rod 34.

[0048] In the application scenario of this embodiment, the fixed side of the telescopic guide rod 34 is used to connect to the driving device, and the top bracket 33 is used to connect to the supporting device. The sliding connection formed by the top bracket 33 relative to the fixed side of the telescopic guide rod 34 forms a guide rail. When the driving device travels on a bumpy road, the driving device drives the fixed side of the telescopic guide rod 34 to translate upward, thereby transmitting the impact force to one end of the shock absorber 10 through the second connecting member 32 connected to the telescopic guide rod 34. After the impact force transmitted to the shock absorber 10 is partially absorbed (by elastic deformation or pneumatic damping), the remaining impact force is transmitted to the top bracket 33 through the first connecting member 31 connected to the other end of the shock absorber, causing the supporting device on the top bracket to produce a smaller upward translation relative to the driving device. Therefore, this embodiment can achieve translational shock absorption of the driving device and the supporting device in the same direction of movement by sliding the top bracket 33 relative to the fixed side of the telescopic guide rod 34.

[0049] In one embodiment, the frame 30 includes a top bracket 33 and a telescopic guide rod 34, the telescopic guide rod 34 has a fixed unit 341 and a movable unit 342, the movable unit 342 is slidably arranged inside the fixed unit 341; the free end of the movable unit 342 is fixedly connected to the top bracket 33 so that the top bracket 33 moves along the guide direction of the fixed unit 341.

[0050] Please refer to Figure 2 、 Figure 3 In one embodiment, the top bracket 33 is provided with a first connecting shaft A, and one end of the shock absorber 10 and the first connecting member 31 are hingedly connected via the first connecting shaft A;

[0051] The first connecting member 31 and the second connecting member 32 are hingedly connected via a second connecting axis B;

[0052] In the application scenario of this embodiment, one end of the shock absorber 10 and the first connecting member 31 are hinged to the top bracket 33 through the first connecting axis A, which is used to meet the rotation requirements of the shock absorber 10 and the first connecting member 31, while simplifying the structure and facilitating the assembly of one end of the shock absorber 10 and the first connecting member 31.

[0053] Among them, the shock absorber 10 is used to form an elastic force on the top bracket 33, and is used to store and release the impact force through the elastic deformation of its own structure when it is subjected to impact and vibration; therefore, it can be considered to set the other end of the shock absorber 10 to be directly hinged to the first connecting member 31, or to set the other end of the shock absorber 10 to be directly hinged to the top bracket 33.

[0054] In one embodiment, a third connecting axis C is provided at the fixed end of the fixing unit 341 , and the second connecting member 32 is hinged to the fixed end of the fixing unit 341 via the third connecting axis C.

[0055] The other end of the shock absorber 10 is provided with a fourth connecting shaft D, and one end of the adjusting device 20 is provided on the fourth connecting shaft D;

[0056] The other end of the adjusting device 20 is hinged to the second connecting member 32 via a fifth connecting shaft E.

[0057] In one embodiment, the position of the fifth connecting axis E can be flexibly arranged and can overlap or not overlap with the third connecting axis C. Overlapping can reduce the number of rotating shaft structures. Non-overlapping can make the position of the fourth connecting axis D more flexible.

The rotation of the convex structure is achieved by toggling the adjustment lock 22, so that the convex structure supports the concave structure or the convex structure is moved away from the concave structure.

[0062] In another application scenario of this embodiment, the adjustment lock 22 is a fixable telescopic structure, and the adjustment lock 22 includes a sliding protrusion that can move in a predetermined direction under the action of an elastic member (such as a spring); the adjustment slider 23 has a recessed structure corresponding to the sliding protrusion, and by adjusting the compression or relaxation stroke of the elastic member, the sliding protrusion can support the recessed structure or the protruding structure can be moved away from the recessed structure.

[0063] In one embodiment, the rotation center of the adjustment lock 22 is set on the fourth connecting axis D, or the rotation center of the adjustment lock 22 can also be set at other parts of the third connecting member 21, and the rotation axis can coincide with, be parallel to, or be orthogonal to the D axis.

The adjustment lock 22 is fixedly connected to the second connecting member 32 via the adjustment slider 23, and the adjustment lock 22 is used to fix the free end of the third connecting member 21 at a current position.

[0066] When the adjustment lock 22 is in the open state, the protruding structure moves away from the recessed structure, and the adjustment slider 23 can retreat along the third connecting member 21. The adjustment slider 23 is spaced a preset distance from the second connecting member 32, and the free end of the third connecting member 21 moves along a preset path to adjust the fixed position.

[0067] Please refer to Figure 5 、 Figure 6 In one embodiment, the second connecting member 32 is provided with first engaging teeth 321 distributed in a fan shape, and the adjusting slider 23 is provided with second engaging teeth 231 corresponding to the first engaging teeth 321 .

[0068] In the application scenario of this embodiment, the first engaging tooth position 321 is fan-shaped and distributed with the fifth connecting axis E as the center of the circle on the side of the second connecting member 32 facing the adjusting slider 23; when the adjusting lock 22 is in the open state, the adjusting slider 23 can slide backward along the third connecting member 21, so that the adjusting slider 23 is separated from the second connecting member 32 by a preset distance, and the free end of the third connecting member 21 can move along the preset moving path formed by the fan-shaped first engaging tooth position 321, thereby adjusting the fixed position of the free end of the third connecting member 21 relative to the second connecting member 32, and quickly adjusting the fixed position of the other end of the shock absorber to change the working stroke.

[0069] Please refer to Figure 5 、 Figure 6 In one embodiment, a toggle rod 221 is further provided on the adjustment lock 22, and the adjustment device 20 is provided with a secondary locking structure, and the adjustment lock 22 is fixed at a preset position through the secondary locking structure.

[0070] In the application scenario of this embodiment, the secondary locking structure is used to ensure that the adjustment lock 22 is not shaken open in a vibrating state; the toggle rod 221 and the secondary locking structure form a certain angle or are collinear, so that the adjustment can be completed by hand without the aid of external tools.

[0071] Please refer to Figure 5 、 Figure 6 In one embodiment, the adjustment lock 22 is provided with an elastic connector 222, and the third connector 21 is provided with a positioning groove 211 corresponding to the elastic connector 222, and the elastic connector 222 and the positioning groove 211 constitute the secondary locking structure.

[0072] In the application scenario of this embodiment, the elastic connector 222 can be a ball screw, which is convenient for manually operating the adjustment lock 22 to disengage the secondary locking structure without the aid of external tools, thereby quickly completing the adjustment.

[0073] Please refer to Figures 7 to 9 In one embodiment, the present invention provides an electric unicycle balancing vehicle, including a shock absorbing mechanism, a vertical bracket 40, a hub motor 50 and a pedal 60.

[0074] The beneficial effects of the present invention are as follows: in the adjustable shock-absorbing mechanism, one end of the shock absorber 10 is rotatably connected to the first connecting member 31 of the frame 30, and the other end is fixedly connected to the second connecting member 32 of the frame 30 through the adjusting device 20; wherein the adjusting device 20 is configured to be able to adjust the working stroke of the shock absorber.
