Description

Technical Field

[0001] The present application relates to the technical field of scooters, and in particular to a scooter. Background Art

[0002] Scooters, especially electric scooters, have the advantages of simple operation, light weight and portability, and long battery life. For short-distance commuters such as office workers and students, electric scooters can provide a fast and convenient way to travel. Electric scooters can help people easily cross congested urban traffic, saving time and energy.

[0003] Scooters are usually equipped with rear shock absorbers. The rear shock absorbers play an important role in improving riding comfort, enhancing control and stability, protecting the scooter structure, and improving safety. The rear shock absorbers can effectively absorb bumps and vibrations on uneven roads to reduce the impact transmitted to the vehicle body and the driver, thereby improving the stability and comfort of the driver when riding on uneven roads.

[0004] In the related art, the scooter is provided with at least one set of connecting rod structures. The connecting rod structure connects the shock absorber, the frame and the rear wheel to ensure that the force of the shock absorber can be effectively transmitted and achieve a smooth shock absorption effect. However, the structure of the connecting rod structure itself and the connection method with the shock absorber are relatively complicated. In particular, when the number of connecting rod structures is large, its reliability is low and it is easy to affect the effect of force transmission. Summary of the invention

[0005] The present application provides a scooter which can solve the problems of complex connection structure and low reliability of the shock absorber.

[0006] The present application provides a scooter, which comprises:

[0007] Rear wheel assembly,

[0008] A vehicle frame, the vehicle frame comprising a first fixing plate;

[0009] A rocker arm shock absorber assembly, the rocker arm shock absorber assembly includes a rocker arm and an elastic member, the rocker arm is rotatably connected to the frame, one end of the rocker arm is connected to the rear wheel assembly, and a second fixing plate is provided at the other end of the rocker arm, the second fixing plate and the first fixing plate are arranged opposite to each other in the up and down direction of the vehicle and form a accommodating portion that can accommodate the elastic member, the first end of the elastic member along the elastic deformation direction is connected to the first fixing plate, and the second end of the elastic member along the elastic deformation direction is connected to the second fixing plate.

[0010] In the scooter provided in the present application, the elastic member can be used to provide a shock-absorbing function for the rear wheel assembly. The rocker arm can be used to transmit the bumping force on the rear wheel assembly to the elastic member, so that the bumps and vibrations on the uneven road surface can be effectively absorbed by the elastic member to reduce the impact transmitted to the frame and the driver, thereby improving the stability and comfort of the driver when riding on uneven roads.

[0011] The embodiment of the present application can provide a rocker arm shock absorbing assembly with a simple structure. When the rocker arm is connected to the frame, a receiving portion for receiving the elastic member can be formed between the first fixing plate of the frame and the second fixing plate of the rocker arm. The first fixing plate and the second fixing plate can fix the elastic member to the receiving portion, thereby fixing the elastic member.

[0012] Specifically, when the rear wheel assembly is located in the pit, the rear wheel assembly sinks downward with the pit, the rocker arm moves in a clockwise direction, and the second fixing plate moves in the direction of the first fixing plate, so that the elastic member generates compression deformation, and the elastic member can absorb part of the bump, thereby buffering the bump and vibration brought to the rider by the pit. Correspondingly, when the rear wheel assembly returns to a flat road surface or is located on a convex hump, the rear wheel assembly moves upward, the rocker arm moves in a counterclockwise direction, and the second fixing plate moves away from the first fixing plate, so that the elastic member rebounds, thereby absorbing part of the bump, thereby buffering the bump and vibration brought to the rider by the convex hump.

[0013] According to an embodiment of the present application, the elastic member is arranged obliquely, and the second end of the elastic member is located on the side of the first end of the elastic member facing the traveling direction.

[0014] When the deformation direction of the elastic member deviates greatly from the movement direction of the second fixing plate that applies the force, the elastic member needs to overcome its own deformation during the deformation process under the action of the second fixing plate. Therefore, on the one hand, it is easy to affect the shock absorption effect, and on the other hand, the elastic member is subjected to uneven force, resulting in local stress concentration on the elastic member, thereby affecting the service life of the elastic member.

[0015] Therefore, in order to solve the above technical problems, in the embodiment of the present application, since the rocker arm is rotatably connected to the frame, the motion trajectory of the second fixed plate of the rocker arm can be arc-shaped. Therefore, by the second end of the elastic member being located on the side of the first end of the elastic member facing the travel direction, the deformation direction of the elastic member can be close to the shape of the arc-shaped motion trajectory of the second fixed plate. In other words, the deformation direction of the elastic member can be tangent to the arc-shaped trajectory of the second fixed plate, and the elastic member can continue to move along its own deformation direction under the force of the second fixed plate, so that the elastic member is evenly stressed, which can more effectively buffer the bumpy feeling and help to increase the service life of the elastic member.

[0016] According to an embodiment of the present application, a plane perpendicular to the forward direction of the vehicle is defined as a main plane, and an angle b between the elastic deformation direction of the elastic member and the main plane is no greater than 15°.

[0017] The angle b between the elastic deformation direction of the elastic member and the main plane should not be too large. For example, when the inclination angle of the elastic member is close to the horizontal plane, the elastic deformation direction of the elastic member also tends to be horizontal. Therefore, a complex connecting rod structure needs to be provided on the rocker arm to convert the arc motion trajectory of the second fixing plate into a motion trajectory close to the deformation direction of the elastic member through the connecting rod structure, which easily leads to a complex structure and complex assembly process of the rocker arm shock absorbing assembly.

[0018] According to one embodiment of the present application, the rocker arm includes a first mounting portion located at one end thereof away from the elastic member and a second mounting portion located between the two ends of the rocker arm, the rocker arm is connected to the rear wheel assembly at the first mounting portion, and the rocker arm is connected to the frame via a first rotating shaft at the second mounting portion, and along the forward direction, the first mounting portion, the second mounting portion, and the elastic member are arranged in sequence.

[0019] With such arrangement, when the rear wheel assembly is bumped, the first mounting portion and the rear wheel assembly rise and fall. The first mounting portion can rotate around the first rotating shaft of the second mounting portion to make the second fixing plate rotate synchronously, so that the second fixing plate can exert a force on the elastic member and absorb the bumping feeling through the elastic member to achieve a shock absorbing effect.

[0020] According to one embodiment of the present application, a first mounting surface and a second mounting surface connected to the elastic member are respectively provided on the first fixing plate and the second fixing plate, and at least one of the first mounting surface and the second mounting surface is inclined relative to the main plane so that the elastic member is inclined.

[0021] Since the first mounting surface and the second mounting surface are connected to the elastic member, the elastic member can be kept in an inclined state by tilting at least one of the first mounting surface and the second mounting surface relative to the main plane, thereby eliminating the need for an additional structure for tilting the elastic member, which is beneficial for simplifying the mounting structure.

[0022] According to an embodiment of the present application, the first fixing plate is provided with a first recessed portion capable of accommodating a portion of the elastic member, and the first mounting surface is located on a bottom wall of the first recessed portion;

[0023] The second fixing plate is provided with a second recessed portion capable of accommodating a portion of the elastic member, the first recessed portion and the second recessed portion are opposite to and face the accommodating portion, and the second mounting surface is located on a bottom wall of the second recessed portion.

[0024] In this way, the first recess can be used to accommodate part of the elastic member, so the side wall of the first recess can be used to fix the first end of the elastic member, so that the first end of the elastic member is not easy to escape from the first recess. Similarly, the second recess can be used to accommodate part of the elastic member, so the side wall of the second recess can be used to fix the second end of the elastic member, so that the second end of the elastic member is not easy to escape from the second recess, so that the elastic member can be fixed by the first recess and the second recess, which is conducive to simplifying the installation process.

[0025] According to an embodiment of the present application, a first guide column is disposed in the first recess, the first guide column protrudes from the first mounting surface, at least part of the elastic member is sleeved on the outside of the first guide column, and the first end of the elastic member abuts against the first mounting surface;

[0026] A second guide column is disposed in the second recess, and the second guide column protrudes from the second mounting surface. At least part of the elastic member is sleeved on the outside of the first guide column, and the second end of the elastic member abuts against the second mounting surface.

[0027] In this way, the first guide post can be used to fix the first end of the elastic member connected to the first mounting surface. Since the first guide post protrudes from the first mounting surface, the first guide post can more effectively prevent the first end of the elastic member from being easily separated from the first recessed portion, thereby reducing the possibility of the elastic member popping out. Similarly, since the second guide post protrudes from the second mounting surface, the second guide post can more effectively prevent the second end of the elastic member from being easily separated from the second recessed portion, thereby reducing the possibility of the elastic member popping out.

[0028] According to one embodiment of the present application, the second guide column and the first guide column have a gap, and the rocker arm shock absorber assembly also includes a first buffer member, which is connected to at least one of the first guide column and the second guide column, and at least part of the first buffer member is located between the gap between the first guide column and the second guide column.

[0029] With such arrangement, the first buffer member can be used to prevent a rigid collision between the first guide column and the second guide column when the elastic member is compressed and deformed, thereby reducing the possibility of vibration and abnormal noise caused by the rigid collision between the first guide column and the second guide column.

[0030] According to one embodiment of the present application, the second fixing plate is located above the first fixing plate, the first recess is recessed in a direction away from the second fixing plate, and a portion of the outer wall of the first recess protrudes from the lower surface of the first fixing plate.

[0031] With such a configuration, when the shock absorbing stroke requirement for the rear wheel assembly is large, part of the outer wall of the first recess can protrude from the lower surface of the first fixing plate to meet the deformation amount of the elastic member. In addition, part of the outer wall of the first recess protrudes from the lower surface of the first fixing plate, which can keep the distance between the first fixing plate and the second fixing plate unchanged, so that the appearance size of the scooter is not easily affected, and the possibility of increasing the distance between the first fixing plate and the second fixing plate, resulting in an increase in the thickness of the first pedal and a scooter that looks bulky is reduced.

[0032] According to one embodiment of the present application, the rocker arm shock absorbing assembly further includes a second buffer and a third buffer;

[0033] The second buffer member is located in the first recess, and the second buffer member at least partially covers the first end of the elastic member to separate the elastic member from the inner wall of the first recess;

[0034] The third buffer is located in the second concave portion, and the third buffer covers the second end of the elastic member to separate the elastic member from the inner wall of the second concave portion.

[0035] In this way, the second buffer can be used to prevent the first end of the elastic member from having rigid friction with the inner wall of the first recess, thereby reducing the possibility of abnormal noise caused by friction and the possibility of friction affecting the service life of the elastic member and the first fixing plate. Similarly, the third buffer can be used to prevent the second end of the elastic member from having rigid friction with the inner wall of the second recess, thereby reducing the possibility of abnormal noise caused by friction and the possibility of friction affecting the service life of the elastic member and the second fixing plate.

[0036] According to one embodiment of the present application, a limit assembly is provided between the frame and the rocker arm, the limit assembly includes a second rotating shaft and a slide structure, the second rotating shaft is located on one of the frame or the rocker arm, the slide structure is located on the other of the frame or the rocker arm, and the slide structure can move within a certain range relative to the second rotating shaft to constrain the relative movement of the rocker arm relative to the frame.

[0037] With such an arrangement, the coordinated movement of the second rotating shaft and the slide structure can be used to constrain the movement range of the rocker arm relative to the frame to protect the elastic member from excessive compression and rebound, thereby protecting the elastic member from damage and increasing the service life of the elastic member.

[0038] According to one embodiment of the present application, the rocker arm shock absorber assembly further includes a fourth buffer member, and the fourth buffer member is located between the second rotating shaft and the inner wall of the slide structure to space the second rotating shaft and the inner wall of the slide structure.

[0039] With such arrangement, the fourth buffer member can be used to prevent rigid collision between the second rotating shaft and the inner wall of the slide structure, thereby avoiding abnormal noise caused by the rigid collision and wear on the second rotating shaft and the inner wall of the slide structure.

[0040] According to an embodiment of the present application, the frame includes a first pedal, the first fixing plate is arranged on the first pedal, the first fixing plate and the first pedal form a receiving space, and at least a portion of the second fixing plate is located in the receiving space.

[0041] With such arrangement, the second fixing plate and the elastic member can be located in the accommodation space formed by the first fixing plate and the first pedal, so that the elastic member is not easily exposed, which is beneficial to reduce the possibility of dust and pebbles getting stuck in the elastic member and affecting the shock absorbing effect of the elastic member.

[0042] According to an embodiment of the present application, the frame further includes a second pedal. In the vertical direction, the second pedal is correspondingly arranged above the elastic member, and the second pedal is detachably connected to the first pedal.

[0043] With such arrangement, when the second pedal is removed from the first pedal, the installation position of the second pedal can be used to install and fix the elastic member and the rocker arm, thereby reserving sufficient installation space for the rocker arm shock absorbing assembly.

[0044] According to one embodiment of the present application, a mounting opening is provided on the first pedal, and along the up and down directions of the vehicle, the orthographic projection of the outer contour of the mounting opening has an overlapping area with the orthographic projection of the second fixing plate, and the second pedal is arranged at the mounting opening of the first pedal to at least partially cover the mounting opening.

[0045] In this way, by setting the orthographic projection of the outer contour of the mounting opening and the orthographic projection of the second fixing plate to have an overlapping area, it can be used to facilitate the fixed installation of the rocker arm shock absorber assembly. During the installation process, the first end of the elastic member can be abutted against the first mounting surface of the first fixing plate, and then the rocker arm can be fixed. The second fixing plate of the rocker arm can be placed into the accommodating space through the mounting opening so that the second mounting surface of the second fixing plate abuts against the second end of the elastic member. After the rocker arm is fixed, the second pedal can be connected to the first pedal to cover the mounting opening.

[0046] According to one embodiment of the present application, along the width direction of the first pedal, the rocker arm includes a first cantilever and a second cantilever opposite to each other, and the second fixing plate is at least partially located between the first cantilever and the second cantilever to connect the first cantilever and the second cantilever.

[0047] Since the second fixing plate is located between the first cantilever and the second cantilever, and the elastic member is also located between the first cantilever and the second cantilever, the bumpy feeling transmitted through the first cantilever and the second cantilever can be absorbed by an elastic member, which is beneficial to saving the number of elastic members and reducing material costs.

[0048] According to one embodiment of the present application, the rear wheel assembly includes a rear wheel, and the first cantilever and the second cantilever are connected to the rear wheel at one end away from the second fixing plate, and along the width direction of the first pedal, the first cantilever and the second cantilever are located on both sides of the rear wheel.

[0049] With such an arrangement, the first cantilever and the second cantilever are arranged on both sides of the rear wheel, so that the bumpy feeling of the rear wheel can be evenly transmitted to the second fixing plate, so that the elastic member can act on the elastic member through the second fixing plate to absorb the bumpy feeling of the rear wheel.

[0050] In addition to the technical problems solved by the embodiments of the present invention described above, the technical features that constitute the technical solutions, and the beneficial effects brought about by the technical features of these technical solutions, other technical problems that can be solved by the scooter provided by the embodiments of the present invention, other technical features included in the technical solutions, and the beneficial effects brought about by these technical features will be further described in detail in the specific implementation methods.

These drawings and text descriptions are not intended to limit the scope of the present application in any way, but to illustrate the concept of the present application to those skilled in the art by referring to specific embodiments. DETAILED DESCRIPTION

[0074] Exemplary embodiments will be described in detail herein, examples of which are shown in the accompanying drawings. When the following description refers to the drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements. The implementation methods described in the following exemplary embodiments do not represent all implementation methods consistent with the present application. On the contrary, they are merely examples of devices and methods consistent with some aspects of the present application as detailed in the attached claims. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present application.

[0075] The scooter may include a non-electric scooter, an electric scooter, a folding scooter, an off-road scooter, etc. The scooter of the embodiment of the present application may be, but is not limited to, the above scooters. The present application will be described by taking the scooter as an electric scooter as an example.

[0076] Electric scooters are a kind of transportation that can be used for both exercise and transportation. They are simple in structure, compact, easy to carry, and have a unique driving experience. Electric scooters also have the advantages of simple operation, flexibility, lightness, portability, low energy consumption, environmental protection, and fast charging, so they are widely used in urban transportation.

[0077] Electric scooters are a means of transportation based on traditional human-powered scooters, combined with power systems and batteries. During riding, the driver stands on the pedals and can control the direction and balance of the electric scooter by manipulating the handlebars at the front of the electric scooter. Therefore, electric scooters are easy to ride, not only have the speed of traditional scooters, but are also labor-saving and convenient.

[0078] Scooters are usually equipped with rear shock absorbers. The rear shock absorbers play an important role in improving riding comfort, enhancing control and stability, protecting the scooter structure, and improving safety. The rear shock absorbers can effectively absorb bumps and vibrations on uneven roads to reduce the impact transmitted to the vehicle body and the driver, thereby improving the stability and comfort of the driver when riding on uneven roads.

[0079] In the related art, the scooter is provided with at least one set of connecting rod structures. The connecting rod structure connects the shock absorber, the frame and the rear wheel to ensure that the force of the shock absorber can be effectively transmitted and achieve a smooth shock absorption effect. However, the structure of the connecting rod structure itself and the connection method with the shock absorber are relatively complicated. In particular, when the number of connecting rod structures is large, its reliability is low and it is easy to affect the effect of force transmission.

[0080] Based on the above technical problems, the applicant has improved the structure of the existing scooter. In the embodiment of the present application, a receiving portion for receiving the elastic member can be formed between the first fixing plate of the frame and the second fixing plate of the rocker arm. The first fixing plate and the second fixing plate can fix the elastic member to the receiving portion to fix the elastic member. The rocker arm shock absorbing assembly has a simple structure, which can solve the problem of complex connection structure and low reliability of the shock absorber.

[0081] The scooter provided by the present application is described below with reference to the accompanying drawings and in combination with specific embodiments.

[0082] Embodiment 1

[0083] Figure 1 FIG. 1 is a schematic diagram of a three-dimensional structure of a scooter 100 according to an embodiment of the present application. Figure 2 1 is a schematic diagram of the front structure of the scooter 100 when the pillar 120 is unfolded according to an embodiment of the present application. Figure 3 for Figure 2 The schematic diagram of the structure of the scooter 100 is shown in a top view. Figure 4 This is a schematic diagram of the front structural view of the scooter 100 when the pillar 120 is folded according to an embodiment of the present application. Figure 5 for Figure 4 The schematic diagram of the structure of the scooter 100 is shown in a top view.

[0084] See also Figures 1 to 5 As shown, the scooter 100 according to the embodiment of the present application includes a handlebar 110 , a column 120 , a frame 130 and a folder 140 .

[0085] The top of the upright post 120 is connected to the handlebar tube 110. Along the length direction of the handlebar tube 110, grips 112 may be respectively provided at both ends of the handlebar tube 110. The driver may manipulate the grips 112 to control the riding direction.

[0086] Along the traveling direction, a front wheel assembly 150 and a rear wheel assembly 160 may be respectively disposed on both sides of the vehicle frame 130. Both the front wheel assembly 150 and the rear wheel assembly 160 may be connected to the vehicle frame 130. The bottom end of the column 120 is connected to the front wheel assembly 150. The distance between the axle axis of the front wheel assembly 150 and the axle axis of the rear wheel assembly 160 is defined as a first distance X1, and the plane where the bottom ends of the front wheel assembly 150 and the rear wheel assembly 160 are located is defined as a first plane.

[0087] The column 120 and the front wheel assembly 150 can be connected by the folder 140. The column 120 can be unfolded or folded relative to the front wheel assembly 150 by the folder 140. Wherein, along the height direction of the column 120, when the column 120 is unfolded, the center of the cross tube 110 has a second distance X2 with the first plane, and the ratio of the second distance X2 (mm) to the first distance X1 (mm) is between 1.2-1.5. When the column 120 is folded, the top end of the folder 140 has a third distance X3 with the first plane, and the ratio of the third distance X3 (mm) to the first distance X1 (mm) is between 0.5-0.65.

[0088] In the embodiment of the present application, by setting the ratio of the second distance X2 to the first distance X1 to be between 1.2-1.5 when the pillar 120 is unfolded, the comfort of the driver pushing the scooter 100 can be satisfied.

[0089] Specifically, when the ratio of the second distance X2 to the first distance X1 is greater than 1.5, the first situation is that the second distance X2 is too large. When the second distance X2 is too large, when the driver stands on the first plane and pushes the scooter 100, both hands need to be raised a certain distance to rest on the gripping portion 112 of the handlebar 110. Especially for a short driver, both hands need to be kept under stress, which is less comfortable.

[0090] When the ratio of the second distance X2 to the first distance X1 is greater than 1.5, the first distance X1 is too small. During the riding of the scooter 100, the driver's feet usually step on the first pedal 131 front and back. Therefore, when the first distance X1 is too small, the size of the first pedal 131 along the travel direction will also decrease, making it difficult to stand on the first pedal 131 with both feet. Most of the rear foot of the driver is in a suspended state, which is easy to cause fatigue and affect the riding experience.

[0091] When the ratio between the second distance X2 and the first distance X1 is less than 1.2, the second distance X2 is too small or the first distance X1 is too large. If the second distance X2 is too small, the distance between the center of the cross tube 110 and the surface (second plane) where the first pedal 131 is located will also be reduced accordingly. Therefore, for tall drivers, it is difficult to stand upright during riding, which affects the riding experience. If the first distance X1 is large, on the one hand, it is easy to increase the overall size of the scooter 100, which is not conducive to portable carrying, packaging and transportation. On the other hand, if the first distance X1 is too large, it is easy to increase the turning radius of the scooter 100, resulting in poor maneuverability, especially in narrow or crowded road conditions. It is difficult to achieve flexible steering. In addition, when the first distance X1 is too large, it is easy to affect the comfort during riding, especially on uneven roads, which is easy to cause the scooter 100 to produce greater vibration and impact when encountering obstacles.

[0092] In addition, by setting the ratio of the third distance X3 to the first distance X1 to be between 0.5-0.65 when the upright column 120 is folded, the folded state can be convenient for the driver to carry and store. In addition, during the product packaging and transportation process, the packaging and transportation costs can be reduced.

[0093] Specifically, during the transportation of the scooter 100, the scooter 100 is in a folded state, and the uprights 120 are folded. At this time, by setting the ratio between the third distance X3 and the first distance X1 to be between 0.5-0.65, the internal space of the container for transporting the scooter 100 can be reasonably utilized, so that more scooters 100 can be stacked in the internal space of the container, thereby reducing the transportation cost.

[0094] The size of the third distance X3 can directly affect the size of the package. If the third distance X3 is too large, it is easy to affect the portability of carrying, storing, ensuring, and transporting. If the first distance X1 is too small, as described above, it will be difficult for the driver's feet to stand on the first pedal 131. At least part of the driver's rear foot is suspended in the air, which is easy to cause fatigue, resulting in a poor riding experience.

[0095] The scooter 100 is usually provided with a front shock absorber and a rear shock absorber. The front shock absorber and the rear shock absorber can be respectively provided on the front wheel assembly 150 and the rear wheel assembly 160. When the ratio between the third distance X3 and the first distance X1 is less than 0.5, one case is that the third distance X3 is too small, and the other case is that the first distance X1 is too large. Among them, as described above, the problem of affecting riding comfort due to the first distance X1 being too large will not be repeated. If the third distance X3 is too small, it is easy to compress the shock absorbing space of the front shock absorber, resulting in affecting the shock absorbing stroke of the front shock absorber, thereby affecting the shock absorbing effect of the front side of the electric vehicle, thereby affecting the stability during riding. If the first distance X1 is small, as described above, it will not be repeated here.

[0096] In some possible implementations, see Figures 1 to 5 As shown, the frame 130 of the embodiment of the present application may include a first pedal 131. In the traveling direction, the first pedal 131 may be located between the front wheel assembly 150 and the rear wheel assembly 160, and connected to the front wheel assembly 150 and the rear wheel assembly 160. During riding, the driver's feet may step on the first pedal 131 one after the other.

[0097] The plane where the upper surface of the first pedal 131 is located is defined as the second plane. A fourth distance X4 is provided between the center of the crossbar 110 and the second plane. The ratio of the fourth distance X4 (mm) to the first distance X1 (mm) is between 1.0-1.25.

[0098] In the embodiment of the present application, when the column 120 is unfolded, the ratio between the fourth distance X4 and the first distance X1 can affect the riding experience of the driver. When the ratio between the fourth distance X4 and the first distance X1 is greater than 1.0-1.25, the size of the fourth distance X4 is too large, or the size of the first distance X1 is too small. When the size of the fourth distance X4 is too large, it is difficult for a small driver to adapt to the height of the gripping portion 112 on the handlebar cross tube 110, so that the driver's arm is always in a stressed state, which affects the riding experience. When the size of the first distance X1 is small, as described above, it will not be repeated here.

[0099] In some practicable embodiments, along the width direction of the first pedal 131 , the ratio of the length L of the cross tube 110 to the second distance X2 is set between 0.4 and 0.6.

[0100] In the embodiment of the present application, the length L of the handlebar tube 110 may affect the riding or pushing comfort of the driver, as well as the stability and controllability during riding. Therefore, by setting the ratio of the length L of the handlebar tube 110 to the second distance X2 to be between 0.4 and 0.6, a better riding experience can be provided for the rider.

[0101] Specifically, the effect of the second distance X2 being too large or too small on the riding experience of the scooter 100 is as described above, and will not be repeated here. The effect of the length L of the handlebar tube 110 on the riding and control experience will be described below.

[0102] During use, the driver's hands hold the gripping parts 112 at both ends of the handlebar tube 110. If the length L of the handlebar tube 110 is too long, on the one hand, it is not conducive to driving in a narrow space, and it is also easy to affect the stability during the steering process. On the other hand, it is not easy for drivers with narrow shoulders to operate. Especially during the pushing process, the driver stands on the first plane, and the driver is located beside the scooter 100. If the length L of the handlebar tube 110 is too long, it is more laborious for the driver to hold the gripping part 112 away from himself, thereby affecting the pushing experience. If the length L of the handlebar tube 110 is too small, it is limited by the shoulder width of the rider group and the arm opening angle during riding, which is not conducive to stability and comfort during riding.

[0103] In some possible implementations, see Figure 2 As shown, the axis of the column 120 of the embodiment of the present application has an inclination angle Y relative to the second plane. The value range of the inclination angle Y is: 12° to 16°.

[0104] In the embodiment of the present application, by setting the inclination angle Y between the axis of the column 120 and the second plane to be greater than 12°, the center of gravity of the scooter 100 can be closer to the center of the frame 130, which is beneficial to improving the overall stability of the scooter 100. However, when the inclination angle Y exceeds 16°, the handlebar 110 at the top of the column 120 will be greatly inclined toward the first pedal 131 and occupy the space above the first pedal 131, resulting in a large space in front of the first pedal that is not suitable for standing, and the optional standing position left for the driver is reduced, which is easy to affect the stability during riding.

[0105] In some possible implementations, see Figure 2 and Figure 4 As shown, the scooter 100 of the embodiment of the present application may further include a connecting rod assembly 170. The connecting rod assembly 170 may be used to connect the front wheel assembly 150, the first pedal 131 and the column 120.

[0106] In some examples, the connecting rod assembly 170 may have three ends, two opposite ends of which may be used to connect the front wheel assembly 150 and the column 120 respectively, and the other end may be used to connect to the first pedal 131 .

[0107] The folder 140 may be disposed at one end of the connecting rod assembly 170 away from the front wheel assembly 150. A fifth distance X5 is provided between the folder 140 and the axle axis of the front wheel assembly 150. The size range of the fifth distance X5 is between 345 mm and 400 mm.

[0108] In the embodiment of the present application, when the size of the fifth distance X5 is less than 345mm, it is easy to affect the shock absorbing stroke of the front shock absorber located at the front wheel assembly 150, thereby affecting the shock absorbing effect of the front wheel assembly 150 and affecting the stability when riding on uneven roads. When the size of the fifth distance X5 is greater than 400mm, it is easy to cause the size of the scooter 100 to increase in the folded state. Therefore, by setting the size range of the fifth distance X5 to be between 345mm-400mm, the above technical problems can be effectively solved.

[0109] In some possible implementations, see Figure 2 and Figure 4 As shown, the scooter 100 of the embodiment of the present application may further include a second pedal 132. One end of the second pedal 132 is connected to the end of the first pedal 131 close to the rear wheel assembly 160. The second pedal 132 extends backward and upward from the end of the first pedal 131 close to the rear wheel assembly 160.

[0110] Since the treadable surface of the first pedal 131 of the scooter 100 is narrow, the driver's feet are usually not able to step on the first pedal 131 completely side by side. Since there are many different driving scenes during riding, the driver's center of gravity will be adjusted forward and backward according to the driving scene. When the driver's center of gravity changes with the riding scene, the heel of the rear foot will naturally rise or fall. For example, when riding deceleration, the driver's center of gravity will change forward, and when riding acceleration, the driver's center of gravity will change backward. When the driving scene of the scooter 100 is complex, there is a situation where the speed change is not a simple acceleration or deceleration, but a rapid change between acceleration and deceleration. In such cases, the rear heel is easy to step on empty space, which affects the stability during riding. Therefore, in the embodiment of the present application, the second pedal 132 can be used to provide support for the rear heel. When driving smoothly, the second pedal 132 can be used to provide support for the rear heel to relieve fatigue of the rear foot. When the vehicle scene changes are complex, the second pedal 132 can be used to provide stable support for the rear foot to avoid stepping on empty space, which affects the stability and safety of riding.

[0111] In some possible implementations, see Figure 2 As shown, the rear wheel assembly 160 has a first spacing Z1 relative to the second plane where the first pedal 131 is located. The second pedal 132 has a second spacing Z2, wherein the second spacing Z2 is less than or equal to the first spacing Z1.

[0112] It should be noted that the first distance Z1 may refer to the distance between the highest point of the rear wheel assembly 160 and the second plane. Similarly, the second distance Z2 may refer to the distance between the highest point of the second pedal 132 and the second plane.

[0113] The rear wheel assembly 160 generally includes a rear wheel 163 and a fender 161. The fender 161 may cover a portion of the rear wheel 163. During driving, the fender 161 may be used to prevent mud, dust, and pebbles on the ground from being splashed onto the rider due to the rotation of the rear wheel 163, so as to keep the rider's clothes and body clean and safe.

[0114] In the embodiment of the present application, the second spacing Z2 is set to be less than or equal to the first spacing Z1, so that the second pedal 132 does not support the rear foot too high, thereby improving the comfort of the second pedal 132. A smaller second spacing Z2 means that the second pedal 132 is smaller in the height direction of the scooter 100. Within the comfortable tilt angle a2 range, it means that the second pedal 132 is smaller in the front-to-back direction of the scooter 100, so it occupies less space behind the first pedal 131, and the structure of the whole vehicle is compact. At the same time, while meeting the driver's rear foot support, reducing the size of the second pedal 132 can also reduce the requirements for the strength of the second pedal 132. On the premise of ensuring the functionality of the second pedal 132, the rationality of the layout and low cost of the whole vehicle are taken into account.

[0115] In some practicable embodiments, the length L of the cross tube 110 is in the range of 550 mm to 590 mm.

[0116] In the embodiment of the present application, as described above, if the length L of the crossbar tube 110 is too large or too small, it may affect the stability and comfort of the vehicle during use, and the length L of the crossbar tube 110 may also affect the thickness of the package. The thickness direction of the package is the same as the width direction of the first pedal 131.

[0117] Specifically, when the length L of the handlebar tube 110 is greater than 590 mm, the thickness of the packaging is likely to increase, resulting in an increase in transportation costs. When the length L of the handlebar tube 110 is less than 550 mm, it is difficult to maintain stability during riding. Therefore, by setting the length L of the handlebar tube 110 to a value range between 550 mm and 590 mm, the driver can have a better riding experience while satisfying the portability of carrying, packaging and transportation.

[0118] For example, the dimension L of the handlebar tube 110 may be 550 mm, 560 mm, 580 mm, 590 mm, etc.

[0119] In some practicable embodiments, the fourth distance X4 between the center of the cross tube 110 and the second plane is in the range of 950 mm to 1050 mm.

[0120] In the embodiment of the present application, by setting the fourth distance X4 between 950 mm and 1050 mm, the comfort and stability of riders of most heights during riding can be met.

[0121] When the driver stands on the first pedal 131, his arms can be naturally placed on the gripping parts 112 at both ends of the handlebar cross tube 110, so that during long-term riding, the driver's arms are not easily fatigued or sore due to being in a bent or over-extended state for a long time, so as to improve the riding comfort, thereby allowing the rider to focus more on riding, which is conducive to improving safety during riding.

[0122] Exemplarily, the fourth distance X4 may be 950 mm, 980 mm, 1000 mm, 1050 mm, etc.

[0123] In some achievable embodiments, the first distance X1 between the axle axis of the front wheel assembly 150 and the axle axis of the rear wheel assembly 160 has a value ranging from 850 mm to 930 mm.

[0124] In the embodiment of the present application, by setting the first distance X1 between 850 mm and 930 mm, the first pedal 131 can have a sufficient size to provide space for the driver's feet when the driver stands on the first pedal 131. In addition, for drivers of different body shapes, the size of the first pedal 131 can allow the driver to move forward and backward on the first pedal 131 for a certain distance and finally adjust to a comfortable standing position for riding.

[0125] It is easy to understand that the first distance X1 is less than or equal to 930 mm, which is conducive to reducing the size of the scooter 100 and improving the portability of carrying, packaging and transportation.

[0126] Exemplarily, the first distance X1 may be 850 mm, 880 mm, 900 mm, 930 mm, etc.

[0127] Embodiment 2

[0128] Figure 6 It is a partial cross-sectional structural schematic diagram of the rear wheel assembly 160 of the scooter 100 according to an embodiment of the present application in a sunken state.

[0129] The embodiment of the present application further provides a scooter 100, in which the same features as those in the first embodiment are not described in detail.

[0130] See also Figures 1 to 6 As shown, the scooter 100 may include a frame 130 , a handlebar 110 , a column 120 , a front wheel assembly 150 , a rear wheel assembly 160 and a first connecting portion 162 .

[0131] The upper end of the column 120 may be connected to the handlebar cross tube 110, and the lower end of the column 120 may be connected to the frame 130. The front wheel assembly 150 may be located in front of the frame 130. The rear wheel assembly 160 may be located behind the frame 130, and the rear wheel assembly 160 includes a fender 161. The first connecting portion 162 is provided on the fender 161, and the first connecting portion 162 is used to fix the column 120 when the scooter 100 is in a folded state.

[0132] The frame 130 is provided with a first pedal 131 and a second pedal 132 connected to each other. One end of the second pedal 132 is connected to the end of the first pedal 131 close to the rear wheel assembly 160. The second pedal 132 extends backward and upward from the end of the first pedal 131 close to the rear wheel assembly 160.

[0133] See also Figure 6 As shown, the plane where the first pedal 131 is located is defined as the first reference plane. It should be noted that the first reference plane and the second plane described above may refer to the same plane. The plane where the highest point of the fender 161 is located is the second reference plane. The second reference plane is parallel to the first reference plane, and the distance between the second reference plane and the first reference plane is the first spacing Z1. The plane where the highest point of the second pedal 132 is located is the third reference plane. The third reference plane is parallel to the first reference plane, and the distance between the third reference plane and the first reference plane is the second spacing Z2.

[0134] The plane where the front end point of the first connecting portion 162 is located is the fourth reference plane. The fourth reference plane is parallel to the first reference plane.

[0135] The distance between the fourth reference plane and the first reference plane is a third distance Z3.

[0136] The second interval Z2 is smaller than the first interval Z1, and the second interval Z2 is smaller than the third interval Z3.

[0137] In the embodiment of the present application, a second pedal 132 may be provided at the end of the first pedal 131 close to the rear wheel assembly 160. The second pedal 132 may be used to provide support for the rear heel. By setting the second spacing Z2 smaller than the first spacing Z1, the second pedal 132 may not easily support the rear foot too high, thereby reducing the height at which the rear foot is supported above the fender 161, causing mud, dust, and pebbles on the ground to splash onto a portion of the area around the rear foot of the rider during riding, thereby soiling the rider's clothes or body, thereby affecting the riding experience.

[0138] Since the first connection portion 162 is disposed on the fender 161, the front end of the first connection portion 162 can be used to put the column 120 in a folded state. The smaller the spacing of the first connection portion 162 relative to the first reference plane, the lower the position of the end of the column 120 away from the folder 140, so that the end of the column 120 away from the folder 140 is easy to collide and interfere with the second pedal 132. Therefore, by setting the second spacing Z2 to be smaller than the third spacing Z3, the highest point of the second pedal 132 can be lower than the front end of the second connection portion 111, which can be used to solve the above technical problems.

[0139] In some examples, the end of the column 120 away from the folder 140 may refer to the end of the column 120 used to connect to the handlebar tube 110. For example, the scooter 100 may include a forehead. The forehead may be disposed at the end of the column 120 away from the folder 140 to fix the handlebar tube 110. Therefore, the end of the column 120 away from the folder 140 may also refer to the forehead, the handlebar tube 110, etc.

[0140] In some possible implementations, see Figure 6 As shown, the third distance Z3 of the embodiment of the present application is not greater than the first distance Z1.

[0141] Since the third spacing Z3 is greater than or equal to the second spacing Z2, that is, the front end point of the second connecting portion 111 can be higher than the highest point of the second pedal 132, it can be used to avoid the end of the column 120 away from the folder 140 from interfering with the second pedal 132. However, if the hook position of the handlebar cross tube 110 in the folded state is adjusted to avoid the auxiliary pedal, the length of the column 120 is increased accordingly, which easily leads to an increase in the fourth distance X4 between the center of the handlebar cross tube 110 and the first reference plane, thereby affecting the riding experience of short drivers. Therefore, in the embodiment of the present application, by setting the third spacing Z3 not greater than the first spacing Z1, in order to solve the problem of interference and collision between the column 120 and the rear auxiliary pedal, the riding comfort suitable for people of different body shapes can still be met.

[0142] In some achievable embodiments, the difference between the first spacing Z1 and the second spacing Z2 of the embodiment of the present application is not less than 10 mm.

[0143] Since there are tolerances in the processing and assembly of the scooter 100, by setting the difference between the first spacing Z1 and the second spacing Z2 to be not less than 10 mm, when the scooter 100 is in the folded state, a safe distance can still be maintained between the end of the column 120 away from the folder 140 and the first pedal 131 to avoid collision and interference between the two. In addition, space for flexible design can also be provided for parameters such as the size of the column 120 and the inclination angle Y of the axis of the column 120 relative to the first reference plane.

[0144] In some possible implementations, see Figure 6 As shown, a straight line passing through the axle center of the rear wheel assembly 160 and perpendicular to the front-rear direction of the vehicle is defined as a first straight line M. The first connecting portion 162 may be located on the side of the first straight line M facing the front wheel assembly 150. A line connecting the front end point of the first connecting portion 162 and the axle center of the rear wheel assembly 160 is a second straight line N. The first straight line M and the second straight line N are arranged at an angle a1.

[0145] In the embodiment of the present application, at least part of the outer contour of the mudguard 161 may extend in an arc surface matching the rear wheel 163. When the first connecting portion 162 is located on the side of the first straight line M facing the front wheel assembly 150, the first connecting portion 162 may be located on the arc surface of the mudguard 161 so that the first straight line M and the second straight line N are set at an angle a1. Therefore, during the folding process of the column 120, the end of the column 120 can be easily along the matching structure on the first connecting portion 162, so that the column 120 can maintain a folded state, thereby achieving stability and safety in the folded state. In other words, if the front end point of the first connecting portion 162 is located on the side of the first straight line M away from the front wheel assembly 150, especially when the second spacing Z2 is less than the third spacing Z3, the highest point of the mudguard 161 is easy to block the end of the column 120 from connecting with the first connecting portion 162, thereby making it difficult for the column 120 to maintain a folded state.

[0146] In some achievable ways, in the embodiment of the present application, the angle a1 between the first straight line M and the second straight line N is not greater than 37°.

[0147] In the embodiment of the present application, when the angle a1 between the first straight line M and the second straight line N is greater than 37°, the distance between the plane where the highest point of the first connection portion 162 is located and the third reference plane is reduced, so that when the column 120 is folded, the end of the column 120 away from the folder 140 is likely to collide with and interfere with the second pedal 132. In addition, since the first connection portion 162 is disposed on the curved surface of the fender 161, when the angle a1 between the first straight line M and the second straight line N is greater than 37°, the first connection portion 162 is relatively forward, so that the size of the column 120 is likely to be reduced, thereby reducing the fourth distance X4 between the center of the cross tube 110 and the first reference plane when the column 120 is unfolded, thereby affecting the riding experience of tall drivers.

[0148] In some examples, the top of the first connection portion 162 may not protrude from the second reference plane where the highest point of the fender 161 is located, so as to improve the overall aesthetics of the scooter 100. In addition, the possibility that the top of the first connection portion 162 protrudes from the second reference plane, causing the first connection portion 162 to be easily damaged by external forces, can also be reduced.

[0149] In some possible implementations, see Figures 1 to 5 As shown, the scooter 100 of the embodiment of the present application may further include a folder 140. One end of the column 120 is connected to the folder 140, and the other end of the column 120 is connected to the handlebar.

[0150] The folder 140 can include a first state and a second state. In the first state, the scooter 100 is in an unfolded state. In the second state, the scooter 100 is in a folded state, and the column 120 can drive the handlebar 110 to flip relative to the frame 130. The handlebar 110 is provided with a second connection portion 111 that cooperates with the first connection portion 162.

[0151] In the embodiment of the present application, the column 120 can be kept in a folded state by connecting the second connection portion 111 on the cross tube 110 to the first connection portion 162 , thereby making it easier for the driver to carry the scooter 100 .

[0152] The embodiment of the present application does not limit the connection method between the second connection part 111 and the first connection part 162. For example, the second connection part 111 and the first connection part 162 can be engaged or hooked with each other.

[0153] In some possible implementations, see Figure 6 As shown, the first connection portion 162 of the embodiment of the present application may be provided with a snap-fitting opening 162a for hooking the second connection portion 111. The opening direction of the snap-fitting opening 162a is inclined downward.

[0154] In the embodiment of the present application, the first connection portion 162 can be arranged obliquely along the curved surface of the fender 161. Therefore, when the pillar 120 is folded to make the second connection portion 111 close to the fender 161, the second connection portion 111 can first abut against the fender 161, and then the fender 161 and the second connection portion 111 have a mutual abutting force, and since the engaging opening 162a of the first connection portion 162 is inclined downward, under the action of the fender 161, the second connection portion 111 can enter the interior of the engaging opening 162a along the inclined inner wall of the engaging opening 162a.

[0155] In some examples, the second connection portion 111 is usually provided with an elastic body. The second connection portion 111 can be retained in the snap-fit ​​opening 162a by the elastic body, so that the column 120 has higher reliability when folded, and prevents the second connection portion 111 from coming out of the snap-fit ​​opening 162a of the first connection portion 162.

[0156] In some examples, the plane where the inner wall of the engaging opening 162a is located is defined as the fifth reference plane. The angle between the fifth reference plane and the second straight line N can be between 75° and 105°. For example, the angle between the fifth reference plane and the second straight line N can be 90°.

[0157] In some possible implementations, see Figure 1 As shown, the second pedal 132 of the embodiment of the present application is detachably connected to the first pedal 131 .

[0158] In the embodiment of the present application, the second pedal 132 can provide support for the rear heel during deceleration or acceleration. In particular, during emergency braking or sudden acceleration, the second pedal 132 is subjected to an instantaneous impact force, which easily causes deformation of the second pedal 132. As a consumable part, the second pedal 132 can be maintained and replaced in a detachable manner, thereby reducing the possibility of increased maintenance costs due to simultaneous replacement of the first pedal 131 or replacement of the frame 130.

[0159] In some possible implementations, see Figure 2 As shown, the second pedal 132 and the fender 161 of the embodiment of the present application may have a gap.

[0160] In the embodiment of the present application, since the second pedal 132 is easily deformed due to the instantaneous impact force during emergency braking or sudden acceleration, a gap between the second pedal 132 and the fender 161 can avoid the force acting on the second pedal 132 being transmitted to the fender 161, causing the fender 161 to also deform.

[0161] Furthermore, when the second pedal 132 is detachably connected to the first pedal 131 , the gap between the fender 161 and the second pedal 132 can reserve installation space for the second pedal 132 to reduce the difficulty of installation.

[0162] In some examples, the second pedal 132 and the fender 161 may be an integral structure, or the second pedal 132 and the fender 161 may be a separate structure. For example, the second pedal 132 and the fender 161 may be detachably connected. This is not limited in the embodiments of the present application.

[0163] In some possible implementations, see Figure 6 As shown, the first pedal 131 and the second pedal 132 of the embodiment of the present application can smoothly transition. The second pedal 132 has a smooth buffer surface.

[0164] In the embodiment of the present application, when the driver stands on the first pedal 131, the forefoot of the rear foot is located on the first pedal 131, and the rear heel is located on the second pedal 132. The smooth transition between the first pedal 131 and the second pedal 132 allows the rider to stand comfortably and steadily on the first pedal 131 and the second pedal 132, thereby improving the comfort during riding. When the second pedal 132 is subjected to an instantaneous impact force, the possibility of the second pedal 132 being easily deformed due to stress concentration can be reduced through the smooth buffer surface of the second pedal 132, which is conducive to improving the service life of the second pedal 132.

[0165] In some possible implementations, see Figure 6 As shown, the second pedal 132 of the embodiment of the present application is tilted relative to the first reference plane, and the tilt angle a2 of the second pedal 132 relative to the first reference plane is between 25° and 45°.

[0166] In the embodiment of the present application, when the inclination angle a2 of the second pedal 132 is greater than 45°, the driver's rear foot has a large inclination angle, which is likely to affect the riding experience, and when the rear foot is inclined at an excessively large inclination angle, the rear foot is easily damaged by the interaction force between the second pedal 132 and the rear foot during emergency braking. When the inclination angle a2 of the second pedal 132 is less than 25°, the second pedal 132 is difficult to play a supporting role.

[0167] In some achievable embodiments, the second spacing Z2 of the second pedal 132 of the embodiment of the present application ranges from 35 mm to 80 mm.

[0168] In the embodiment of the present application, by setting the second spacing Z2 of the second pedal 132 to a value range between 35 mm and 80 mm, a more comfortable support effect can be provided for the rider, and the second pedal 132 itself can have better structural strength.

[0169] Embodiment 3

[0170] Figure 7 It is a partial cross-sectional structural schematic diagram of the rear wheel assembly 160 of the scooter 100 according to an embodiment of the present application in a floating state. Figure 8 for Figure 1 A magnified schematic diagram of center A.

[0171] The embodiment of the present application further provides a scooter 100, wherein the features identical to those in the first and second embodiments are not described in detail.

[0172] In some possible implementations, see Figure 1 , Figure 2 and Figure 7 As shown, the scooter 100 according to the embodiment of the present application may include a rear wheel assembly 160 , a frame 130 , and a swing arm shock absorbing assembly 180 .

[0173] The vehicle frame 130 may include a first fixing plate 133. The rocker shock absorbing assembly 180 may include a rocker arm 181 and an elastic member 182. The rocker arm 181 may be rotatably connected to the vehicle frame 130. One end of the rocker arm 181 may be connected to the rear wheel assembly 160. A second fixing plate 1811 is provided at the other end of the rocker arm 181. The second fixing plate 1811 and the first fixing plate 133 may be arranged opposite to each other along the up-down direction of the vehicle and form a receiving portion for receiving the elastic member 182. A first end 1821 of the elastic member 182 along the elastic deformation direction is connected to the first fixing plate 133, and a second end 1822 of the elastic member 182 along the elastic deformation direction is connected to the second fixing plate 1811.

[0174] The elastic member 182 of the embodiment of the present application can be used to provide a shock absorbing function for the rear wheel assembly 160. The swing arm 181 can be used to transmit the bumping force on the rear wheel assembly 160 to the elastic member 182, so that the bumps and vibrations on the uneven road surface can be effectively absorbed by the elastic member 182 to reduce the impact transmitted to the frame 130 and the driver, thereby improving the stability and comfort of the driver when riding on uneven roads.

[0175] The embodiment of the present application can provide a rocker arm shock absorbing assembly 180 with a simple structure. When the rocker arm 181 is connected to the frame 130, a receiving portion for receiving the elastic member 182 can be formed between the first fixing plate 133 of the frame 130 and the second fixing plate 1811 of the rocker arm 181. The first fixing plate 133 and the second fixing plate 1811 can fix the elastic member 182 to the receiving portion, thereby fixing the elastic member 182.

[0176] Among them, reference Figure 6 and Figure 7 In the direction shown, when the rear wheel assembly 160 is located in the pit, the rear wheel assembly 160 sinks downward with the pit, the rocker arm 181 moves in the clockwise direction, and the second fixing plate 1811 moves in the direction of the first fixing plate 133, so that the elastic member 182 produces compression deformation, and the elastic member 182 can absorb part of the bump, thereby buffering the bump and vibration brought to the rider by the pit. Correspondingly, when the rear wheel assembly 160 returns to a flat road surface or is located on a convex hump, the rear wheel assembly 160 moves upward, the rocker arm 181 moves in the counterclockwise direction, and the second fixing plate 1811 moves away from the first fixing plate 133, so that the elastic member 182 rebounds, thereby absorbing part of the bump, and then buffering the bump and vibration brought to the rider by the convex hump.

[0177] In some possible implementations, see Figure 6 and Figure 7As shown, the elastic member 182 of the embodiment of the present application can be arranged obliquely. The second end 1822 of the elastic member 182 can be located on the side of the first end 1821 of the elastic member 182 facing the traveling direction.

[0178] It should be noted that when the deformation direction of the elastic member 182 deviates greatly from the movement direction of the second fixing plate 1811 that applies the force, the elastic member 182 needs to overcome its own deformation during the deformation under the action of the second fixing plate 1811. Therefore, on the one hand, the shock absorption effect is easily affected, and on the other hand, the elastic member 182 is subjected to uneven force, resulting in local stress concentration on the elastic member 182, thereby affecting the service life of the elastic member 182.

[0179] Therefore, in order to solve the above technical problems, in the embodiment of the present application, since the rocker arm 181 is rotatably connected to the frame 130, the motion track of the second fixing plate 1811 of the rocker arm 181 can be arc-shaped. Therefore, by the second end 1822 of the elastic member 182 being located on the side of the first end 1821 of the elastic member 182 facing the travel direction, the deformation direction of the elastic member 182 can be close to the arc-shaped motion track shape of the second fixing plate 1811. In other words, the deformation direction of the elastic member 182 can be tangent to the arc-shaped track of the second fixing plate 1811, and the elastic member 182 can continue to move along its own deformation direction under the force of the second fixing plate 1811, so that the elastic member 182 is subjected to uniform force, which can more effectively buffer the bumpy feeling and help to increase the service life of the elastic member 182.

[0180] In some possible implementations, see Figure 6 As shown, a plane perpendicular to the vehicle's forward direction is defined as a principal plane. An angle b between the elastic deformation direction of the elastic member 182 and the principal plane is not greater than 15°.

[0181] The angle b between the elastic deformation direction of the elastic member 182 and the main plane should not be too large. For example, when the inclination angle of the elastic member 182 is close to the horizontal plane, the elastic deformation direction of the elastic member 182 also tends to be horizontal. Therefore, a complex connecting rod structure needs to be provided on the rocker arm 181 to convert the arc motion trajectory of the second fixing plate 1811 into a motion trajectory close to the deformation direction of the elastic member 182 through the connecting rod structure, which easily leads to a complex structure and complex assembly process of the rocker arm shock absorbing assembly 180.

[0182] In some examples, the angle b between the elastic deformation direction of the elastic member 182 and the main plane may be 10°, 12°, 13°, etc.

[0183] In some possible implementations, see Figure 7As shown, the swing arm 181 of the embodiment of the present application may include a first mounting portion 1812 located at one end thereof away from the elastic member 182 and a second mounting portion 1813 located between the two ends of the swing arm 181. The swing arm 181 is connected to the rear wheel assembly 160 at the first mounting portion 1812. The swing arm 181 is connected to the frame 130 via the first rotating shaft 183 at the second mounting portion 1813. Along the forward direction of the vehicle, the first mounting portion 1812, the second mounting portion 1813, and the elastic member 182 are sequentially arranged.

[0184] In the embodiment of the present application, along the traveling direction, one end of the rocker arm 181 is a second fixing plate 1811, and the second fixing plate 1811 corresponds to the elastic member 182, so as to directly apply a force to the elastic member 182. The other end of the rocker arm 181 is a first mounting portion 1812, so as to be connected to the rear wheel assembly 160. The second mounting portion 1813 is located between the second fixing plate 1811 and the first mounting portion 1812. The second fixing plate 1811 and the first mounting portion 1812 can rotate synchronously relative to the second mounting portion 1813.

[0185] Therefore, when the rear wheel assembly 160 is bumped, the first mounting portion 1812 and the rear wheel assembly 160 rise and fall. The first mounting portion 1812 can rotate around the first rotating shaft 183 of the second mounting portion 1813 to make the second fixing plate 1811 rotate synchronously, so that the second fixing plate 1811 can apply force to the elastic member 182, and the elastic member 182 absorbs the bumping feeling to achieve a shock absorbing effect.

[0186] In some examples, relative to the first mounting portion 1812, the second mounting portion 1813 can be close to the second fixing plate 1811 so that the torque between the second mounting portion 1813 and the second fixing plate 1811 is smaller than the torque between the second mounting portion 1813 and the first mounting portion 1812, thereby absorbing the larger bumps experienced by the rear wheel assembly 160 through the smaller deformation of the elastic member 182.

[0187] In some examples, the second mounting portion 1813 may be a hole structure. The first rotating shaft 183 may be disposed on the vehicle frame 130. The first rotating shaft 183 may be passed through the second mounting portion 1813, so that the vehicle frame 130 and the rocker arm 181 are rotatably connected through the first rotating shaft 183.

[0188] In some possible implementations, see Figure 7 As shown, the first fixing plate 133 and the second fixing plate 1811 of the embodiment of the present application are respectively provided with a first mounting surface 133a and a second mounting surface 1811a connected to the elastic member 182. At least one of the first mounting surface 133a and the second mounting surface 1811a is inclined relative to the main plane so that the elastic member 182 is inclined.

[0189] In the embodiment of the present application, since the first mounting surface 133a and the second mounting surface 1811a are connected to the elastic member 182, the elastic member 182 can be kept in an inclined state by tilting at least one of the first mounting surface 133a and the second mounting surface 1811a relative to the main plane, thereby eliminating the need for an additional structure for tilting the elastic member 182, which is beneficial for simplifying the mounting structure.

[0190] In some examples, taking the case where the second fixing plate 1811 is located above the first fixing plate 133 as an example, the first mounting surface 133a can be inclined relative to the main plane, so that when the elastic member 182 is placed on the first fixing plate 133, the elastic member 182 is inclined through the first mounting surface 133a. Alternatively, the second mounting surface 1811a can be inclined relative to the main plane, so that when the elastic member 182 is placed on the first fixing plate 133, the deformation direction of the elastic member 182 is inclined through the second mounting surface 1811a inclined with respect to the main plane. Furthermore, both the first mounting surface 133a and the second mounting surface 1811a can be inclined relative to the main plane. The first mounting surface 133a and the second mounting surface 1811a can be parallel surfaces to each other, which is not limited in this embodiment.

[0191] In some examples, taking the first mounting surface 133a as an example of being inclined relative to the main plane, when the angle between the first mounting surface 133a and the main plane is 77°, the angle b between the elastic deformation direction of the elastic member 182 and the main plane can be 13°.

[0192] In some possible implementations, see Figure 7 As shown, the first fixing plate 133 of the embodiment of the present application is provided with a first recess 134 that can accommodate part of the elastic member 182. The first mounting surface 133a is located at the bottom wall of the first recess 134. The second fixing plate 1811 is provided with a second recess 184 that can accommodate part of the elastic member 182. The first recess 134 and the second recess 184 are opposite and face the accommodating portion, and the second mounting surface 1811a is located at the bottom wall of the second recess 184.

[0193] In the embodiment of the present application, the first recess 134 can be used to accommodate part of the elastic member 182, so the side wall of the first recess 134 can be used to fix the first end 1821 of the elastic member 182, so that the first end 1821 of the elastic member 182 is not easy to escape from the first recess 134. Similarly, the second recess 184 can be used to accommodate part of the elastic member 182, so the side wall of the second recess 184 can be used to fix the second end 1822 of the elastic member 182, so that the second end 1822 of the elastic member 182 is not easy to escape from the second recess 184, so that the elastic member 182 can be fixed by the first recess 134 and the second recess 184, which is conducive to simplifying the installation process.

[0194] In some examples, the first end 1821 of the elastic member 182 may abut against the bottom wall of the first recess 134, ie, the first mounting surface 133a. The second end 1822 of the elastic member 182 may abut against the bottom wall of the second recess 184, ie, the second mounting surface 1811a.

[0195] In some examples, the first recess 134 and the first fixing plate 133 may be an integral structure. The second recess 184 and the second fixing plate 1811 may also be an integral structure. Taking the first recess 134 and the first fixing plate 133 as an example, the first recess 134 may be an integrally formed structure with the first fixing plate 133, or the first recess 134 may be an integral structure that is not easily disassembled with the first fixing plate 133 by welding, crimping, etc. This is not specifically limited in the embodiments of the present application.

[0196] In some possible implementations, see Figure 7 As shown, a first guide column 1341 is provided in the first recess 134 of the embodiment of the present application. The first guide column 1341 protrudes from the first mounting surface 133a, and at least a portion of the elastic member 182 is sleeved outside the first guide column 1341. The first end 1821 of the elastic member 182 can abut against the first mounting surface 133a. A second guide column 1841 is provided in the second recess 184. The second guide column 1841 protrudes from the second mounting surface 1811a, and at least a portion of the elastic member 182 is sleeved outside the first guide column 1341, and the second end 1822 of the elastic member 182 can abut against the second mounting surface 1811a.

[0197] In the embodiment of the present application, the first guide column 1341 can be used to fix the first end 1821 of the elastic member 182 connected to the first mounting surface 133a. Since the first guide column 1341 protrudes from the first mounting surface 133a, the first guide column 1341 can more effectively prevent the first end 1821 of the elastic member 182 from being easily separated from the first recess 134, thereby reducing the possibility of the elastic member 182 popping out. Similarly, since the second guide column 1841 protrudes from the second mounting surface 1811a, the second guide column 1841 can more effectively prevent the second end 1822 of the elastic member 182 from being easily separated from the second recess 184, thereby reducing the possibility of the elastic member 182 popping out.

[0198] Furthermore, the first guide column 1341 and the second guide column 1841 can be used to provide guidance for the deformation direction of the elastic member 182 to prevent the elastic member 182 from being separated from the deformation direction, thereby affecting the shock absorption effect and service life of the elastic member 182 .

[0199] In some examples, the axis of the first guide column 1341 may be perpendicular to the first mounting surface 133a. The axis of the second guide column 1841 may also be perpendicular to the second mounting surface 1811a.

[0200] In some examples, the first guide column 1341 and the second guide column 1841 may have a gap so that when the elastic member 182 is compressed and deformed, the first guide column 1341 and the second guide column 1841 are not likely to collide and produce abnormal noise. Alternatively, at least one of the first guide column 1341 and the second guide column 1841 may have a buffering effect so that when the first guide column 1341 and the second guide column 1841 collide, the interaction force between the two can be buffered to reduce the possibility of abnormal noise.

[0201] In some possible implementations, see Figure 7 As shown, the second guide column 1841 of the embodiment of the present application may have a gap with the first guide column 1341. The rocker arm shock absorbing assembly 180 may also include a first buffer 185. The first buffer 185 may be connected to at least one of the first guide column 1341 and the second guide column 1841. At least part of the first buffer 185 may be located between the gap between the first guide column 1341 and the second guide column 1841.

[0202] In the embodiment of the present application, the first buffer member 185 can be used to prevent a rigid collision between the first guide column 1341 and the second guide column 1841 from occurring when the elastic member 182 undergoes compression deformation, thereby reducing the possibility of vibration and abnormal noise caused by a rigid collision between the first guide column 1341 and the second guide column 1841.

[0203] In some examples, taking the connection between the first buffer member 185 and the first guide column 1341 as an example, the first buffer member 185 and the first guide column 1341 can be fixedly connected by threaded connection, interference fit, bonding, etc.

[0204] In some examples, the structure of the first buffer member 185 may be, but is not limited to, a columnar structure. The material of the first buffer member 185 may be, but is not limited to, rubber, PP (polypropylene), and the like.

[0205] In some possible implementations, see Figure 7 As shown, the second fixing plate 1811 of the embodiment of the present application may be located above the first fixing plate 133. The first recess 134 may be recessed in a direction away from the second fixing plate 1811.

[0206] In some examples, part of the outer wall of the first recess 134 may not protrude from the lower surface of the first fixing plate 133. For example, the first recess 134 may be located in the receiving portion of the first fixing plate 133 and the second fixing plate 1811.

[0207] In some other examples, a portion of the outer wall of the first recess 134 may protrude from the lower surface of the first fixing plate 133 .

[0208] In the embodiment of the present application, when the shock absorbing stroke requirement of the rear wheel assembly 160 is large, part of the outer wall of the first recess 134 may protrude from the lower surface of the first fixing plate 133 to meet the deformation amount of the elastic member 182. In addition, part of the outer wall of the first recess 134 protrudes from the lower surface of the first fixing plate 133, which can keep the distance between the first fixing plate 133 and the second fixing plate 1811 unchanged, so that the appearance size of the scooter 100 is not easily affected, and the distance between the first fixing plate 133 and the second fixing plate 1811 increases, which reduces the possibility that the thickness of the first pedal 131 increases and the scooter 100 looks bulky.

[0209] In some possible implementations, see Figure 7 As shown, the rocker arm shock absorbing assembly 180 of the embodiment of the present application may further include a second buffer 186 and a third buffer 187. The second buffer 186 is located in the first recess 134, and the second buffer 186 at least partially covers the first end 1821 of the elastic member 182 to separate the elastic member 182 and the inner wall of the first recess 134. The third buffer 187 is located in the second recess 184. The third buffer 187 covers the second end 1822 of the elastic member 182 to separate the elastic member 182 and the inner wall of the second recess 184.

[0210] In the embodiment of the present application, the second buffer member 186 can be used to prevent the first end 1821 of the elastic member 182 from having rigid friction with the inner wall of the first recess 134, thereby reducing the possibility of abnormal noise caused by friction and the possibility of friction affecting the service life of the elastic member 182 and the first fixing plate 133. Similarly, the third buffer member 187 can be used to prevent the second end 1822 of the elastic member 182 from having rigid friction with the inner wall of the second recess 184, thereby reducing the possibility of abnormal noise caused by friction and the possibility of friction affecting the service life of the elastic member 182 and the second fixing plate 1811.

[0211] In some examples, the structure of the second buffer 186 can match the structure of the first recess 134. The structure of the third buffer 187 can match the structure of the second recess 184.

[0212] In some examples, the second buffer 186 may be fixed in the first recess 134 via the first guide post 1341. The third buffer 187 may be fixed in the second recess 184 via the second guide post 1841.

[0213] In some possible implementations, see Figure 7As shown, a limit assembly 190 is provided between the frame 130 and the rocker arm 181 of the embodiment of the present application. The limit assembly 190 may include a second rotating shaft 191 and a slideway structure 192. The second rotating shaft 191 may be located on one of the frame 130 or the rocker arm 181. The slideway structure 192 is located on the other of the frame 130 or the rocker arm 181. The slideway structure 192 may move within a certain range relative to the second rotating shaft 191, so as to constrain the relative movement of the rocker arm 181 relative to the frame 130.

[0214] In the embodiment of the present application, the coordinated movement of the second rotating shaft 191 and the slide structure 192 can be used to constrain the movement range of the rocker arm 181 relative to the frame 130, so as to protect the elastic member 182 from excessive compression and rebound, thereby protecting the elastic member 182 from damage and increasing the service life of the elastic member 182.

[0215] In some examples, the relative motion range between the slide structure 192 and the second rotating shaft 191 can be set according to the deformation amount of the elastic member 182 .

[0216] In some examples, the second rotating shaft 191 may be located on the vehicle frame 130, the slideway structure 192 may be located on the rocker arm 181, and the second rotating shaft 191 may be arranged through the slideway structure 192 to move on the travel path of the slideway structure 192. Alternatively, the second rotating shaft 191 may be arranged on the rocker arm 181, and the slideway structure 192 may be located on the vehicle frame 130, which is not limited in the embodiments of the present application.

[0217] In some examples, the movement trajectory of the slide structure 192 may be in the shape of an arc.

[0218] In some practicable embodiments, the rocker arm damping assembly 180 of the embodiment of the present application may further include a fourth buffer member, which may be located between the second rotating shaft 191 and the inner wall of the slideway structure 192 to space the second rotating shaft 191 and the inner wall of the slideway structure 192 .

[0219] In the embodiment of the present application, the fourth buffer member can be used to prevent rigid collision between the second rotating shaft 191 and the inner wall of the slide structure 192, thereby avoiding abnormal noise caused by rigid collision and wear on the second rotating shaft 191 and the inner wall of the slide structure 192.

[0220] In some examples, the fourth buffer member may be sleeved on the outer wall of the second rotating shaft 191 to space the second rotating shaft 191 from the inner wall of the slideway structure 192. Alternatively, the fourth buffer member may be sleeved on the inner wall of the slideway structure 192. This is not limited in the embodiments of the present application.

[0221] In some possible implementations, see Figure 1 and Figure 2As shown, the frame 130 of the embodiment of the present application may include a first pedal 131. A first fixing plate 133 may be disposed on the first pedal 131. The first fixing plate 133 and the first pedal 131 enclose a receiving space. At least a portion of the second fixing plate 1811 is located in the receiving space.

[0222] In the embodiment of the present application, the second fixing plate 1811 and the elastic member 182 can be located in the accommodation space formed by the first fixing plate 133 and the first pedal 131, so that the elastic member 182 is not easily exposed, which is beneficial to reduce the possibility of dust and pebbles getting stuck in the elastic member 182 and affecting the shock-absorbing effect of the elastic member 182.

[0223] In some examples, the vehicle frame 130 may further include a connecting plate. The connecting plate is connected to the first fixing plate 133 and to the first pedal 131. An angle may be formed between the connecting plate and the first fixing plate 133. A wire clamping structure for fixing a wire harness may be provided on the connecting plate.

[0224] In some possible implementations, see Figure 1 and Figure 8 As shown, the frame 130 of the embodiment of the present application may further include a second pedal 132. In the vertical direction, the second pedal 132 is correspondingly arranged above the elastic member 182, and the second pedal 132 is detachably connected to the first pedal 131.

[0225] In the embodiment of the present application, the second pedal 132 can be used to support the rear heel of the driver. The second pedal 132 is detachably connected to the first pedal 131, and when the second pedal 132 is detached from the first pedal 131, the installation position of the second pedal 132 can be used to install and fix the elastic member 182 and the rocker arm 181, so that sufficient installation space can be reserved for the rocker arm shock absorbing assembly 180.

[0226] In some possible implementations, see Figure 1 and Figure 8 As shown, the first pedal 131 of the embodiment of the present application may be provided with a mounting opening 131a. Along the up-down direction of the vehicle, the orthographic projection of the outer contour of the mounting opening 131a and the orthographic projection of the second fixing plate 1811 have an overlapping area. The second pedal 132 is arranged at the mounting opening 131a of the first pedal 131 to at least partially cover the mounting opening 131a. In other words, the orthographic projection of the mounting opening 131a along the up-down direction of the vehicle is the orthographic projection of the mounting opening 131a on the first plane. Similarly, the orthographic projection of the second fixing plate 1811 along the up-down direction of the vehicle is the orthographic projection of the second fixing plate 1811 on the first plane.

[0227] In the embodiment of the present application, by setting the orthographic projection of the outer contour of the mounting opening 131a and the orthographic projection of the second fixing plate 1811 to have an overlapping area, it can be used to facilitate the fixed installation of the rocker arm shock absorbing assembly 180. During the installation process, the first end 1821 of the elastic member 182 can be abutted against the first mounting surface 133a of the first fixing plate 133, and then the rocker arm 181 can be fixed. The second fixing plate 1811 of the rocker arm 181 can be placed into the accommodating space through the mounting opening 131a, so that the second mounting surface 1811a of the second fixing plate 1811 abuts against the second end 1822 of the elastic member 182. After the rocker arm 181 is fixed, the second pedal 132 can be connected to the first pedal 131 to cover the mounting opening 131a.

[0228] In some possible implementations, see Figure 8 As shown, the rocker arm 181 may include a first cantilever 1814 and a second cantilever 1815 opposite to each other along the width direction of the first pedal 131. At least a portion of the second fixing plate 1811 may be located between the first cantilever 1814 and the second cantilever 1815 to connect the first cantilever 1814 and the second cantilever 1815.

[0229] In the embodiment of the present application, since the second fixed plate 1811 is located between the first cantilever 1814 and the second cantilever 1815, and the elastic member 182 is also located between the first cantilever 1814 and the second cantilever 1815, the bumpy feeling transmitted through the first cantilever 1814 and the second cantilever 1815 can be absorbed by an elastic member 182, which is beneficial to saving the number of elastic members 182 and reducing material costs.

[0230] The first cantilever 1814 and the second cantilever 1815 are respectively located on both sides of the second fixed plate 1811. Therefore, the first cantilever 1814 and the second cantilever 1815 can transfer the bumpy feeling of the rear wheel assembly 160 to the second fixed plate 1811 respectively, and the first cantilever 1814 and the second cantilever 1815 can share the bumpy feeling together to improve the service life of the first cantilever 1814 and the second cantilever 1815.

[0231] In some achievable embodiments, the rear wheel assembly 160 may include a rear wheel 163. One end of the first cantilever 1814 and the second cantilever 1815 away from the second fixing plate 1811 is connected to the rear wheel 163. Along the width direction of the first pedal 131, the first cantilever 1814 and the second cantilever 1815 are located on both sides of the rear wheel 163.

[0232] In the embodiment of the present application, the first cantilever 1814 and the second cantilever 1815 are arranged on both sides of the rear wheel 163, so as to evenly transfer the bumpy feeling of the rear wheel 163 to the second fixed plate 1811, so that the elastic member 182 can act on the elastic member 182 through the second fixed plate 1811 to allow the elastic member 182 to absorb the bumpy feeling of the rear wheel 163.

[0233] It should be noted here that the numerical values ​​and numerical ranges involved in this application are approximate values. Due to the influence of the manufacturing process, there may be a certain range of errors, which can be considered negligible by those skilled in the art.

[0234] In the description of the embodiments of the present application, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, or it can be an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements.
