Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of vehicles, in particular to a seat cushion assembly and a vehicle. BACKGROUND

[0002] Vehicles such as scooters, bicycles, motorcycles, tricycles, etc. have the advantages of simple operation, lightness and portability, and can help people easily cross congested urban traffic and save time and effort.

[0003] As the part directly contacted by the rider, the comfort of the seat cushion can directly affect the safety and riding experience of the rider. Especially when encountering bumpy road conditions, the rider will bear continuous bumps and impacts, which can easily lead to fatigue and even lumbar injury.

[0004] In the related art, a spring is provided below the seat cushion. The spring stores and releases energy through elastic deformation to relieve the impact force caused by bumpy road conditions. However, the spring repeatedly rebounds after being shaken and needs a certain amount of time to attenuate, and the buffering effect is limited, which affects the riding experience. UTILITY MODEL CONTENT

[0005] The present application provides a seat cushion assembly and a vehicle, which can solve the problem of poor damping and buffering effect affecting the riding experience.

[0006] In one aspect, the present application provides a seat cushion assembly, comprising:

[0007] a seat cushion body;

[0008] a seat cushion support provided at the bottom of the seat cushion body, the seat cushion support being used to support the seat cushion body;

[0009] a damping mechanism, the damping mechanism comprising an inner part, a damping layer and an outer cylinder, the outer cylinder extending along the width direction of the vehicle, and the damping layer being located between the inner part and the outer cylinder along the radial direction of the outer cylinder;

[0010] wherein one of the inner part and the outer cylinder is connected with the seat cushion support, and the other of the inner part and the outer cylinder is used to be connected with the frame of the vehicle.

[0011] The seat cushion assembly provided by the present application can absorb the acting force of the relative rotation between the inner part and the outer cylinder through the damping layer of the damping mechanism, so that when one of them rotates, the other can remain relatively stable, so that the seat cushion body can remain relatively stable, thereby relieving the impact force caused by bumps when the road conditions are bumpy, and improving the riding safety and comfort of the rider.

[0012] Specifically, one of the inner part and the outer cylinder of the damping mechanism is connected with the seat cushion support, and the other is connected with the frame. For example, the inner part is connected with the frame, and the outer cylinder is connected with the seat cushion support. When encountering a bumpy road, the frame moves up and down with the uneven road surface. The inner part connected with the frame can rotate around itself. Because the damping layer is arranged between the inner part and the outer cylinder, the damping layer deforms under the rotation of the inner part. For example, the inner wall of the damping layer that is attached to the inner part can move synchronously with the inner part, while the outer wall of the damping layer that is attached to the outer cylinder can remain relatively fixed. Therefore, the deformation of the damping layer can make the outer cylinder relatively stable, so that the seat cushion support connected with the outer cylinder can remain stable, and the seat cushion body connected with the seat cushion support can also remain stable. The damping layer can absorb the bump caused by the bumpy road through its own deformation to buffer the bumping impact force, so that the rider is less likely to feel the bump, thereby improving the comfort, safety and experience of riding.

[0013] It is easy to understand that the damping mechanism is connected with the seat cushion support through one of the inner part and the outer cylinder, and is connected with the seat cushion body through the other. Therefore, the damping mechanism has fewer mounting points, and the damping mechanism does not easily occupy a large internal space between the seat cushion body and the frame, thereby making the vehicle more aesthetically pleasing and simple.

[0014] Especially, when the vehicle is a hard-tail vehicle, the rear wheel of the vehicle is directly and rigidly fixed to the tail of the frame, and the tail of the frame is a whole rigid structure. Through the damping mechanism of the embodiment of the present application, on the one hand, the damping effect of the hard-tail vehicle can be achieved, and the riding experience can be improved. On the other hand, the aesthetic appearance of the vehicle can also be improved.

[0015] According to an embodiment of the present application, the inner part includes an inner cylinder and an inner shaft body.

[0016] Along the radial direction of the outer cylinder, the inner shaft body, the inner cylinder, the damping layer and the outer cylinder are sequentially arranged, and the inner shaft body and the inner cylinder are a unitary structure.

[0017] In the embodiment of the present application, the inner shaft body can be used to connect with one of the seat cushion support or the frame. The outer cylinder can be used to connect with the other of the seat cushion support or the frame. The inner cylinder can be sleeved outside the inner shaft body. The damping layer can fill the gap between the inner cylinder and the outer cylinder.

[0018] The inner shaft body and the inner cylinder are a unitary structure. The outer wall of the inner shaft body can be attached to the inner cylinder to make them move synchronously. For example, when the inner shaft body rotates, the inner cylinder rotates synchronously, so that the part of the damping layer attached to the inner cylinder can deform. The part of the damping layer away from the inner cylinder can remain relatively stationary, so that the outer cylinder can remain relatively stationary.

[0019] According to one embodiment of the present application, the inner part comprises an inner cylinder and an inner shaft body, the inner cylinder is sleeved on the outside of part of the inner shaft body, and the inner shaft body is fixedly connected with the inner cylinder through a shaft sleeve, wherein the inner shaft and the inner cylinder have a hollow part therebetween.

[0020] In the embodiment of the present application, the inner cylinder and the inner shaft body can be a split structure. At least part of the shaft sleeve can be located between the inner shaft body and the inner cylinder along the radial direction of the outer cylinder, so that the inner shaft body and the inner cylinder can move synchronously. The hollow part between the inner shaft body and the inner cylinder can reduce the overall weight of the damping mechanism, which is conducive to the lightweight design of the seat cushion assembly.

[0021] According to one embodiment of the present application, the inner part is fixedly connected with the seat cushion support, and the outer cylinder is fixedly connected with the vehicle frame.

[0022] In the embodiment of the present application, when the inner part is connected with the seat cushion support and the outer cylinder is connected with the vehicle frame, the vehicle frame moves up and down when encountering a bumpy road condition. The outer cylinder connected with the vehicle frame rotates. Since the damping layer is arranged between the inner part and the outer cylinder, the damping layer deforms under the rotation of the outer cylinder. The damping layer can keep the inner part located therein relatively stable, so that the seat cushion support connected with the inner part can be kept stable, and thus the seat cushion body connected with the seat cushion support can also be kept stable. The rider is less likely to feel bumps on the bumpy road, which is conducive to improving the comfort, safety and experience of riding.

[0023] According to one embodiment of the present application, a support is further included, the support is connected with the vehicle frame, and the outer cylinder is connected with the support.

[0024] In the embodiment of the present application, the support can be used to connect the outer cylinder and the vehicle frame. The vehicle frame, the support and the outer cylinder can move synchronously. When encountering a bumpy road condition, the vehicle frame floats up and down and drives the outer cylinder to move synchronously through the support. The outer cylinder can rotate around its own axis. The damping layer is located between the outer cylinder and the inner cylinder, so that the inner cylinder can be kept relatively fixed by the deformation of the damping layer when the outer cylinder rotates. Since the inner cylinder moves synchronously with the inner shaft body, and the inner shaft body is fixedly connected with the seat cushion support, the seat cushion support can be kept relatively stable when encountering a bumpy road condition, so that the seat cushion body can be kept stable.

[0025] According to one embodiment of the present application, the support is an integral structure.

[0026] In the embodiment of the present application, the support can be used to connect the damping mechanism and the vehicle frame. By setting the support as an integral structure, the assembly of parts can be reduced, the structure of the vehicle can be simplified, and the appearance of the vehicle can be improved. In addition, the material maintenance cost can also be reduced.

[0027] According to one embodiment of the present application, the inner part is fixedly connected with the vehicle frame, and the outer cylinder is fixedly connected with the seat cushion support.

[0028] In the embodiments of the present application, when the inner part is connected with the vehicle frame and the outer cylinder is connected with the seat cushion support, if the vehicle frame moves up and down on a bumpy road, the inner part connected with the vehicle frame can rotate around the axis of the outer cylinder. Since the damping layer is arranged between the inner part and the outer cylinder, the damping layer deforms under the rotation of the inner part. The outer cylinder outside the damping layer can remain relatively stable, so that the seat cushion support connected with the outer cylinder can remain stable, and thus the seat cushion body connected with the seat cushion support can also remain stable. The rider can not easily feel the bumpiness on the bumpy road, which is conducive to improving the comfort, safety and experience of riding.

[0029] According to one embodiment of the present application, a support part is further included, and the damping mechanism is connected with the vehicle frame through the support part, and the outer cylinder is connected with the seat cushion body.

[0030] In the embodiments of the present application, the support part can be used to connect the inner shaft body and the vehicle frame. The vehicle frame, the support part, the inner shaft body and the inner cylinder can move synchronously. When the vehicle frame floats up and down on a bumpy road, the inner shaft body is driven to move synchronously by the support part. The inner shaft body and the inner cylinder can rotate synchronously around their own axes. The damping layer is arranged between the outer cylinder and the inner cylinder, so that the outer cylinder can remain relatively fixed when the inner cylinder rotates through the deformation of the damping layer. Since the outer cylinder is fixedly connected with the seat cushion support, the seat cushion support can remain relatively stable when the bumpy road is encountered, so that the seat cushion body can remain stable.

[0031] According to one embodiment of the present application, the support part includes a first support and a second support, the first support and the second support are oppositely arranged along the width direction of the vehicle, and the first support and the second support are respectively connected with two ends of the inner shaft body.

[0032] In the embodiments of the present application, the first support and the second support can be respectively used to connect with the two ends of the inner shaft body. The first support and the second support can provide stable support for the two ends of the inner shaft body, so as to improve the connection stability of the damping mechanism and the vehicle frame, so that the damping mechanism can buffer the bumping impact force when the bumpy road is encountered, thereby improving the riding comfort and safety.

[0033] According to one embodiment of the present application, one of the seat cushion support and the vehicle frame is provided with a limiting part, and when the limiting part is connected with the other one of the seat cushion support and the vehicle frame, the seat cushion body has a spacing between the rear fender of the vehicle and / or the vehicle frame.

[0034] In the embodiments of the present application, when encountering a bumpy road, the frame floats up and down, so that the cushion body and the frame are close to or away from each other. By setting the limiting piece, the maximum angle of relative rotation between the inner part and the outer part can be constrained, so as to constrain the minimum distance between the frame and the cushion body, so that the cushion body and the rear fender of the vehicle, or the cushion body and the frame are not easy to collide.

[0035] It is easy to understand that when the cushion body collides with at least one of the rear fender or the frame, the rear fender or the frame will exert a reaction force on the cushion body, so that the rider will feel a vibration, which will affect the riding experience. Moreover, the collision between the cushion body and the rear fender or the frame is easy to cause the deformation of the rear fender or the frame.

[0036] The limiting piece can be arranged on the cushion bracket. In a normal riding state, the limiting piece and the frame can have a spacing in the height direction of the vehicle. When encountering a bumpy road, the limiting piece contacts the frame, and the cushion body and the rear fender have a spacing, and the cushion body and the frame also have a spacing.

[0037] Alternatively, the limiting piece can also be arranged on the frame. In a normal riding state, the limiting piece and the cushion bracket can have a spacing in the height direction of the vehicle. When encountering a bumpy road, when the limiting piece contacts the cushion bracket, the cushion body and the rear fender have a spacing, and the cushion body and the frame also have a spacing.

[0038] According to an embodiment of the present application, at least one of the cushion bracket and the frame is provided with a buffer piece;

[0039] When the limiting piece is arranged on the cushion bracket, at least part of the buffer piece is located between the limiting piece and the frame in the height direction of the vehicle; or when the limiting piece is arranged on the frame, at least part of the buffer piece is located between the limiting piece and the cushion bracket in the height direction of the vehicle.

[0040] In the embodiments of the present application, under a bumpy road condition, the buffer piece can be used to buffer the impact force between the limiting piece and the frame or the limiting piece and the cushion bracket, so that the limiting piece and the frame or the limiting piece and the cushion bracket are not easy to collide rigidly, thereby reducing the possibility of the vibration caused by the rigid collision to the rider, which affects the riding safety and comfort.

[0041] According to an embodiment of the present application, one of the cushion bracket and the support is provided with a limiting piece, and when the limiting piece is connected to the other one of the cushion bracket and the support, the cushion body and the rear fender of the vehicle and / or the frame have a spacing.

[0042] In the embodiments of the present application, the support member can be arranged on the frame. In the height direction of the vehicle, the support member can have a surface opposite to the cushion support. The limiting member can be arranged on the cushion support, or the limiting member can also be arranged on the surface of the support member facing the cushion support.

[0043] According to an embodiment of the present application, at least one of the cushion support and the support member is provided with a buffer member.

[0044] When the limiting member is arranged on the cushion support, in the height direction of the vehicle, at least part of the buffer member is located between the limiting member and the support member; or when the limiting member is arranged on the support member, in the height direction of the vehicle, at least part of the buffer member is located between the limiting member and the cushion support.

[0045] In the embodiments of the present application, under bumpy road conditions, the buffer member can be used to buffer the impact force between the limiting member and the support member or between the limiting member and the cushion support, so that rigid collision between the limiting member and the frame or between the limiting member and the cushion support is not easy to occur, thereby reducing the possibility of vibration caused by rigid collision to the rider, affecting the safety and comfort of riding.

[0046] According to an embodiment of the present application, the limiting member is arranged on the side of the cushion support facing the frame, and the buffer member is arranged on the limiting member; and / or the buffer member is arranged on the frame; and / or the buffer member is arranged on the support member.

[0047] In the embodiments of the present application, when the limiting member is arranged on the side of the cushion support facing the frame, the buffer member can be arranged on the structure of the limiting member itself. The buffer member can also be arranged on the area of the frame corresponding to the limiting member. When the support member is arranged on the surface of the frame facing the cushion support, the buffer member can also be arranged on the area of the support member corresponding to the limiting member, so that the buffer member makes it not easy to produce rigid connection between the limiting member and the frame or the support member.

[0048] According to an embodiment of the present application, in the width direction of the vehicle, the buffer member is close to both ends of the limiting member.

[0049] In the embodiments of the present application, the buffer member can be arranged at both ends of the limiting member. In other words, the buffer member can not necessarily be arranged on the entire limiting member. The area of the limiting member corresponding to the frame is provided with a buffer member to reduce the material cost of the buffer member.

[0050] On the other hand, the present application provides a vehicle comprising a frame and a cushion assembly according to any one of the above embodiments. The cushion assembly can be arranged on the frame.

[0085] The specific embodiments of the present application have been shown and described by the above drawings, and will be described in more detail hereinafter. These drawings and written descriptions are not intended to limit the scope of the concept of the present application by any means, but to illustrate the concept of the present application to those skilled in the art by referring to specific embodiments. DETAILED DESCRIPTION

[0086] The exemplary embodiments will be described in detail herein with reference to the attached drawings. In the following description, like reference numerals refer to like elements throughout the description. The following exemplary embodiments described are not representative of all embodiments consistent with the present application. Rather, they are merely examples of apparatuses and methods consistent with some aspects of the present application as detailed in the appended claims. It is clear that the described embodiments are a part of, but not all of, embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative work are within the scope of protection of the present application.

[0087] The cushion assembly of the embodiments of the present application can be applied to a vehicle. The vehicle can be a bicycle, a scooter, a motorcycle, etc. In addition, the vehicle can be an electric vehicle. The present application takes a motorcycle as an example for description. The motorcycle can be an electric motorcycle.

[0088] As a component directly contacted by a rider, the comfort of the cushion can directly affect the safety and riding experience of the rider. Especially when encountering a bumpy road, the rider will bear continuous bumps and impacts, which can easily lead to fatigue and even lumbar injury.

[0089] In the related art, a spring is arranged below the cushion. The spring stores and releases energy through elastic deformation to alleviate the impact force caused by the bumpy road. However, the spring repeatedly rebounds after being shaken and needs a certain time to attenuate, and the buffering effect is limited, which results in poor riding experience.

[0090] Based on the above technical problems, the applicant improves the structure of the existing cushion assembly. In the embodiments of the present application, the damping mechanism includes an inner part, a damping layer, and an outer cylinder. When encountering a bumpy road, the frame vibrates, and the outer cylinder or the inner part connected with the frame can rotate. When one of the outer cylinder and the inner part rotates, the damping layer between the outer cylinder and the inner part can absorb the vibration generated by the rotation through its own deformation to buffer the bumping feeling. Therefore, the other one of the outer cylinder and the inner part can be relatively stable, so that the cushion body can be relatively stable, and the rider on the cushion body is not easy to feel the bumping feeling, which is beneficial to improve the riding experience.

[0091] The cushion assembly 100 and the vehicle 10 provided by the present application will be described below with reference to the accompanying drawings and in conjunction with specific embodiments.

[0092] Referring to Figures 1 to 6 As shown in the drawings, the cushion assembly 100 of the embodiments of the present application includes a cushion body 110, a cushion support 120, and a damping mechanism 130.

[0093] The cushion support 120 is arranged at the bottom of the cushion body 110. The cushion support 120 is used to support the cushion body 110. Along the length direction X of the vehicle 10, at least part of the damping mechanism 130 is located at the front side area below the cushion body 110. It should be noted that the front side area below the cushion body 110 can refer to the area of the front 1 / 2 of the cushion body 110 in the length direction X of the vehicle 10.

[0094] The damping mechanism 130 includes an inner part 131, a damping layer 132 and an outer cylinder 133. The outer cylinder 133 extends along the width direction Y of the vehicle 10. Along the radial direction of the outer cylinder 133, the damping layer 132 is located between the inner part 131 and the outer cylinder 133.

[0095] One of the inner part 131 and the outer cylinder 133 is connected with the cushion support 120. The other of the inner part 131 and the outer cylinder 133 is used to be connected with the frame 200 of the vehicle 10.

[0096] In the embodiment of the present application, the damping layer 132 of the damping mechanism 130 can be used to absorb the acting force of the relative rotation between the inner part 131 and the outer cylinder 133, so that when one of them rotates, the other can remain relatively stable, so that the cushion body 110 can remain relatively stable, thereby relieving the impact force caused by the bumping in the bumpy road conditions, and improving the riding safety and comfort of the rider.

[0097] Specifically, one of the inner part 131 and the outer cylinder 133 of the damping mechanism 130 is connected with the cushion support 120, and the other is connected with the frame 200. Exemplarily, taking the inner part 131 connected with the frame 200 and the outer cylinder 133 connected with the cushion support 120 as an example, when encountering bumpy road conditions, the frame 200 moves up and down with the uneven road surface. The inner part 131 connected with the frame 200 can rotate around itself. Since the damping layer 132 is arranged between the inner part 131 and the outer cylinder 133, the damping layer 132 deforms under the rotation of the inner part 131. For example, the inner wall of the damping layer 132 adhering to the inner part 131 can move synchronously with the inner part 131, while the outer wall of the damping layer 132 adhering to the outer cylinder 133 can remain relatively fixed. Therefore, the deformation of the damping layer 132 can make the outer cylinder 133 remain relatively stable, so that the cushion support 120 connected with the outer cylinder 133 can remain stable, and thus the cushion body 110 connected with the cushion support 120 can also remain stable. The damping layer 132 can absorb the bumping caused by the bumpy road conditions by deforming itself, so as to buffer the bumping impact force, so that the rider is not easy to feel the bumping, thereby being conducive to improving the comfort, safety and experience of riding.

[0098] In some examples, the damping layer 132 can be a cylindrical structure. The inner wall of the damping layer 132 is attached to the inner component 131. The outer wall of the damping layer 132 is attached to the outer cylinder 133. When the inner component 131 rotates, the inner wall of the damping layer 132 can rotate synchronously with the inner component 131. Because the damping layer 132 can undergo elastic deformation, the outer wall of the damping layer 132 can remain relatively stationary, so that the outer cylinder 133 connected to the outer wall can remain relatively stable. Similarly, when the outer cylinder 133 rotates, the outer wall of the damping layer 132 can rotate synchronously with the outer cylinder 133. Because the damping layer 132 can undergo elastic deformation, the inner wall of the damping layer 132 can remain relatively stationary, so that the inner component 131 connected to the inner wall can remain relatively stable.

[0099] It is easy to understand that the shock absorption mechanism 130 is connected to the seat support 120 through one of the inner component 131 and the outer cylinder 133, and to the seat body 110 through the other of the inner component 131 and the outer cylinder 133. Therefore, the shock absorption mechanism 130 has fewer mounting points, and the shock absorption mechanism 130 does not occupy a large internal space between the seat body 110 and the frame 200, thus making the vehicle 10 more aesthetically pleasing and simple overall.

[0100] In particular, when the vehicle 10 is a hardtail vehicle 10, the rear wheel 400 of the vehicle 10 is directly and rigidly fixed to the rear of the frame 200, and the rear of the frame 200 is an integral rigid structure. Through the shock absorption mechanism 130 of this embodiment, on the one hand, a better shock absorption effect can be achieved for the hardtail vehicle 10, improving the riding experience. On the other hand, it can also improve the aesthetics of the vehicle 10.

[0101] Furthermore, along the length direction X of the vehicle 10, at least part of the shock absorption mechanism 130 can be located in the front area below the seat body 110. Therefore, the shock absorption mechanism 130 can occupy a small space in the rear area below the seat body 110, or even not occupy the rear area below the seat body 110, so that the rear area of ​​the seat body 110 can be suspended on the frame 200, thereby improving the simplicity and aesthetics of the vehicle 10.

[0102] In some examples, the material of the damping layer 132 can be a damping material, such as rubber. The damping material damping layer 132 can convert vibrations and bumps into internal potential energy through internal friction, thereby reducing the impact of bumps transmitted to the rider's body.

[0103] See also some of the possible implementation methods. Figure 1 As shown, along the length direction X of the vehicle 10, the seat body 110 is adjustablely mounted on the seat support 120 to adjust the distance between the seat body 110 and the handlebars 300 of the vehicle 10.

[0104] In the embodiment of the present application, the cushion body 110 is adjustable relative to the cushion support 120, so that the rider can adjust the distance between the cushion body 110 and the handlebar 300 according to the own needs, thereby meeting the riding comfort of different height groups and different riding posture requirement groups.

[0105] Specifically, for a tall rider, the cushion body 110 can be adjusted to move away from the handlebar 300 to increase the distance between the handlebar 300 and the cushion body 110. For a relatively short rider, the cushion body 110 can be adjusted to move close to the handlebar 300 to reduce the distance between the handlebar 300 and the cushion body 110.

[0106] In some implementable manners, referring to Figure 4 The cushion body 110 and the cushion support 120 of the embodiment of the present application are provided with an adjusting hole 100a extending along the length direction X of the vehicle 10. The other one of the cushion body 110 and the cushion support 120 is provided with an adjusting piece 101 which can be arranged in the adjusting hole 100a. The adjusting piece 101 is slidably connected to the adjusting hole 100a, so as to adjust the relative position of the cushion body 110 relative to the cushion support 120.

[0107] In the embodiment of the present application, the adjusting hole 100a can form a slide for the adjusting piece 101 to slide, so that the cushion body 110 moves along the length direction X or the backward direction of the vehicle 10 during the adjustment of the cushion body 110, and is not easy to deviate to the width direction Y or other directions, thereby ensuring that the cushion body 110 can be located in the middle region of the width direction Y of the vehicle 10, so as to ensure the stability and comfort during the riding.

[0108] In addition, the position of the cushion body 110 relative to the frame 200 is adjusted by sliding the adjusting piece 101 in the adjusting hole 100a, which is simple and convenient for the rider to operate.

[0109] It should be noted that the lower part of the cushion body 110 can be provided with the adjusting piece 101. The cushion support 120 can be provided with the adjusting hole 100a extending along the length direction X of the vehicle 10. Alternatively, the bottom of the cushion body 110 can be provided with the adjusting hole 100a extending along the length direction X of the vehicle 10. The cushion support 120 can be provided with the adjusting piece 101 protruding towards the cushion body 110. In the embodiment, it is not limited.

[0110] In some examples, the cushion body 110 and the cushion support 120 can be locked by a locking piece.

[0111] For example, the adjusting piece 101 can be a screw structure. The locking piece can be a nut.

[0112] In some possible implementations, referring to Figure 2 and Figure 3 , a plane perpendicular to the width direction Y of the vehicle 10 is defined as a first projection plane, at least part of the projection of the shock-absorbing mechanism 130 on the first projection plane is below the projection of the seat cushion body 110 on the first projection plane, and along the length direction X of the vehicle 10, the rear edge of the projection of the shock-absorbing mechanism 130 on the first projection plane does not exceed the front 1 / 3 of the projection of the seat cushion body 110 on the first projection plane.

[0113] In the embodiments of the present application, at least part of the projection of the shock-absorbing mechanism 130 on the first projection plane is below the projection of the seat cushion body 110 on the first projection plane, so that the seat cushion body 110 can shield at least part of the shock-absorbing mechanism 130. Moreover, by setting the rear edge of the projection of the shock-absorbing mechanism 130 on the first projection plane to not exceed the front 1 / 3 of the projection of the seat cushion body 110 on the first projection plane, the seat cushion body 110 can be provided with the shock-absorbing mechanism 130 in at least 2 / 3 of the area on the rear side. At least 2 / 3 of the area on the rear side of the seat cushion body 110 can be in a floating state, which is conducive to achieving the neatness and aesthetics of the vehicle 10.

[0114] In some examples, along the height direction Z of the vehicle 10, at least part of the shock-absorbing mechanism 130 can be located between the seat cushion body 110 and the frame 200.

[0115] In some examples, the seat cushion support 120 can be located below the seat cushion body 110 for supporting the seat cushion body 110. The shock-absorbing mechanism 130 can be arranged on the seat cushion support 120.

[0116] In some examples, when a rider looks down at the vehicle 10 from the height direction Z of the vehicle 10, the seat cushion body 110 can shield the shock-absorbing mechanism 130.

[0117] In some examples, the seat cushion support 120 can have an internal space for accommodating at least part of the shock-absorbing mechanism 130. The seat cushion support 120 can shield at least part of the shock-absorbing mechanism 130. For example, when a rider looks at the vehicle 10 from the width direction Y of the vehicle 10, the shock-absorbing mechanism 130 can be shielded in the internal space of the seat cushion support 120.

[0118] In some possible implementations, referring to Figure 2 and Figure 3 , a plane perpendicular to the width direction Y of the vehicle 10 is defined as a first projection plane. Along the length direction X of the vehicle 10, the projection of the axis of the outer cylinder 133 on the first projection plane does not exceed the front 1 / 4 of the projection of the seat cushion body 110 on the first projection plane.

[0119] In this embodiment, by setting the projection of the axis of the outer cylinder 133 onto the first projection plane to be no more than the front 1 / 4 of the projection of the seat body 110 onto the first projection plane, the shock absorption mechanism 130 can be positioned close to the front end of the seat body 110, so that the rear area of ​​the seat body 110 has a distance along the height direction Z between it and the frame 200. This allows the rear area of ​​the seat body 110 to be in a suspended state, which is beneficial to improving the aesthetics of the vehicle 10.

[0120] It should be noted that, in this embodiment, the front end refers to the area close to the front wheel along the length direction X of the vehicle 10.

[0121] See also some of the possible implementation methods. Figure 3 and Figure 4 As shown, along the height direction Z of the vehicle 10, the orthographic projection of the seat cushion bracket 120 is located inside the orthographic projection of the seat cushion body 110.

[0122] In this embodiment, since the seat cushion body 110 is adjustable to the seat cushion bracket 120 along the length direction X of the vehicle 10, by setting the orthographic projection of the seat cushion body 110 along the height direction Z of the vehicle 10 to be within the orthographic projection of the seat cushion body 110 along the height direction Z of the vehicle 10, when adjusting the position of the seat cushion body 110 relative to the seat cushion bracket 120, the front end of the seat cushion bracket 120 will not exceed the front end of the seat cushion body 110, and the rear end of the seat cushion bracket 120 will not exceed the rear end of the seat cushion body 110.

[0123] It is easy to understand that when the orthographic projection of the saddle support 120 exceeds the orthographic projection of the saddle body 110, on the one hand, when looking down at the vehicle 10 along the height direction Z, the saddle support 120 is exposed to the rider's line of sight, which is detrimental to the aesthetics of the vehicle 10. On the other hand, the rider is likely to come into contact with the saddle support 120 during riding. Since the saddle support 120 is usually a rigid structure, contact between the rider and the rigid saddle support 120 can easily affect riding comfort. Therefore, by setting the orthographic projection of the saddle support 120 to be located inside the orthographic projection of the saddle body 110, the above-mentioned technical problems can be effectively solved.

[0124] See also some of the possible implementation methods. Figures 4 to 6 As shown, the bottom of the seat cushion body 110 in this embodiment of the application is provided with a recess 110a. The recess 110a extends along the length direction X of the vehicle 10. At least a portion of the seat cushion support 120 is located in the recess 110a.

[0125] In the embodiment of the present application, the recessed portion 110a of the cushion body 110 can provide a preliminary positioning function for the cushion support 120 during the assembly process of the cushion body 110 and the cushion support 120. When part of the cushion support 120 is located in the recessed portion 110a, the adjusting member 101 can be easily corresponded to the adjusting hole 100a, which is beneficial to realize the quick installation of the cushion body 110 and the cushion support 120.

[0126] In addition, since the recessed portion 110a can extend along the length direction X of the vehicle 10, when the position of the cushion body 110 relative to the frame 200 is adjusted, the recessed portion 110a can provide a guiding function for the relative movement of the cushion body 110 and the cushion support 120, so that the cushion body 110 can move along the length direction X of the vehicle 10. In addition, when the riding posture of the rider changes, the cooperation between the recessed portion 110a and the cushion support 120 can increase the stability of the cushion body 110 relative to the whole vehicle, improve the service life of the cushion support 120 and the adjusting member 101, and improve the riding experience.

[0127] Specifically, when the distance between the cushion body 110 and the handlebar 300 is adjusted, the locking member on the adjusting member 101 can be loosened first. So that the adjusting member 101 can slide in the adjusting hole 100a. Then, the cooperation between the recessed portion 110a and the cushion support 120 can make the cushion body 110 and the cushion support 120 produce relative movement along the length direction X of the vehicle 10.

[0128] In some examples, the surfaces of the cushion body 110 and the cushion support 120 relative to each other along the height direction Z of the vehicle 10 can be flat. For example, the bottom wall of the recessed portion 110a and the surface of the cushion support 120 facing the cushion body 110 can be mutually attached, so as to increase the contact area between the cushion support 120 and the cushion body 110, so that the cushion support 120 can provide stable support for the cushion body 110.

[0129] In some realizable ways, referring to FIGS. Figure 4 and Figure 5 The recessed portion 110a of the embodiment of the present application has a first end 1101 and a second end 1102 along the length direction X of the vehicle 10. The first end 1101 is closer to the front end of the cushion body 110 relative to the second end 1102. The first end 1101 is located on the side of the cushion support 120 facing the front end of the cushion body 110. And / or, the cushion support 120 is located on the side of the second end 1102 facing the front end of the cushion body 110.

[0130] In the embodiment of the present application, by setting the first end 1101 of the recessed portion 110a to be located on the side of the front end of the cushion body 110 facing the cushion support 120, when adjusting the sliding of the cushion body 110 along the length direction X of the vehicle 10, the front end of the cushion support 120 will not exceed the first end 1101 of the recessed portion 110a, so that the front end of the cushion support 120 will not exceed the front end of the cushion body 110, thereby not easily affecting the appearance of the vehicle 10, nor easily causing the rider to contact the rigid cushion support 120.

[0131] By setting the cushion support 120 to be located on the side of the front end of the cushion body 110 facing the second end 1102, when adjusting the sliding of the cushion body 110 along the length direction X of the vehicle 10, the rear end of the cushion support 120 will not exceed the second end 1102 of the recessed portion 110a, so that the rear end of the cushion support 120 will not exceed the rear end of the cushion body 110, thereby not easily affecting the appearance of the vehicle 10, nor easily causing the rider to contact the rigid cushion support 120.

[0132] In addition, along the length direction X of the vehicle 10, when the rear side area of the cushion body 110 is raised, by setting the rear end of the cushion support 120 not to exceed the second end 1102 of the recessed portion 110a, the possibility of the rear end of the cushion support 120 and the raised area of the rear side of the cushion body 110 having a distance along the height direction Z of the vehicle 10, resulting in a reduction in the contact area between the cushion support 120 and the cushion body 110, affecting the support effect of the cushion support 120 on the cushion body 110, can be reduced. And when the vehicle 10 is viewed from the width direction Y of the vehicle 10, the area of the cushion support 120 exposed to the recessed portion 110a is larger, which is not conducive to the appearance of the vehicle 10.

[0133] In some realizable ways, the length of the recessed portion 110a of the embodiment of the present application along the length direction X of the vehicle 10 is greater than or equal to the sum of the length of the adjusting hole 100a and the length of the cushion support 120.

[0134] In the embodiment of the present application, the length of the adjusting hole 100a extends along the length direction X of the vehicle 10, and the length of the adjusting hole 100a can constrain the range of adjustment of the cushion body 110 relative to the cushion support 120, so that the cushion body 110 has two limit positions along the length direction X of the vehicle 10. During the adjustment of the cushion body 110, the cushion support 120 and the cushion body 110 move relatively. When the cushion body 110 is in the two limit positions, the front end of the cushion support 120 is located in the recessed portion 110a, and the rear end of the cushion support 120 is also located in the recessed portion 110a, in other words, the front end of the cushion support 120 will not exceed the first end 1101 of the recessed portion 110a, and the rear end of the cushion support 120 will not exceed the second end 1102 of the recessed portion 110a.

[0135] It is easy to understand that the two extreme positions can refer to the minimum distance between the seat body 110 and the handlebar 300, and the maximum distance between the seat body 110 and the handlebar 300, respectively.

[0136] See also some of the possible implementation methods. Figure 4 As shown, along the width direction Y of the vehicle 10, the width dimension of the recess 110a matches the width dimension of the seat support 120.

[0137] In this embodiment, along the width direction Y of the vehicle 10, the width of the recess 110a is matched with the width of the seat support 120. The recess 110a can limit the seat support 120 in the width direction Y. When the rider turns or leans to the side, the seat body 110 is less likely to shake due to the cooperation between the recess 110a and the seat support 120, thereby improving the stability and safety of the rider during the riding process.

[0138] In some examples, the recess 110a may have two inner walls opposite each other along the width direction Y of the vehicle 10. The two inner walls can be constrained to each other with the seat support 120. When the vehicle 10 is viewed directly along the width direction Y of the vehicle 10, the two inner walls of the recess 110a can partially cover the seat support 120, which helps to improve the aesthetics of the vehicle 10.

[0139] See also some of the possible implementation methods. Figures 4 to 6 As shown, the bottom of the seat cushion body 110 in this embodiment of the application is also provided with a reinforcing portion 110b. Along the width direction Y of the vehicle 10, at least one side of the recessed portion 110a is provided with a reinforcing portion 110b.

[0140] In this embodiment, the reinforcing portion 110b can be used to increase the strength of the seat body 110 to provide more stable support for the rider. The recessed portion 110a and the reinforcing portion 110b can work together to increase the strength of the seat body 110 to provide safe and stable support during riding.

[0141] In some examples, the reinforcing part 110b may be, but is not limited to, a recess, a convex part, a reinforcing rib, etc., and is not limited in the embodiments of this application.

[0142] In some examples, the recess 110a may be located close to the center along the width direction Y of the vehicle 10. A reinforcing portion 110b is provided on at least one side of the recess 110a. For example, reinforcing portions 110b may be provided on both sides of the recess 110a.

[0143] See also some of the possible implementation methods. Figure 2 and Figure 3As shown, along the length direction X of the vehicle 10, the cushion body 110 includes a flat portion 111 and a raised portion 112. The flat portion 111 is located at the front side of the raised portion 112. The cushion bracket 120 is arranged on the flat portion 111, and at least part of the cushion bracket 120 extends to the raised portion 112.

[0144] In the embodiment, the raised portion 112 can be raised upward relative to the flat portion 111. The raised portion 112 can make the surface of the cushion body 110 in contact with the rider conform to the physiological curve of the ischium, so that the cushion body 110 can uniformly disperse the gravity of the rider and relieve or even eliminate fatigue during long-time riding. In addition, when the riding is accelerated or uphill, the raised portion 112 can provide support for the rider, so that the rider can maintain a stable posture and reduce the possibility of affecting the riding stability caused by the backward sliding of the hips.

[0145] In the embodiment, the raised portion 112 can be raised upward relative to the flat portion 111. The raised portion 112 can make the surface of the cushion body 110 in contact with the rider conform to the physiological curve of the ischium, so that the cushion body 110 can uniformly disperse the gravity of the rider and relieve or even eliminate fatigue during long-time riding. In addition, when the riding is accelerated or uphill, the raised portion 112 can provide support for the rider, so that the rider can maintain a stable posture and reduce the possibility of affecting the riding stability caused by the backward sliding of the hips.

[0146] In particular, when the cushion body 110 is formed by using an injection molding process, at least part of the cushion bracket 120 extends to the raised portion 112, and at least part of the cushion bracket 120 and the raised portion 112 can conform to each other to support part of the raised portion 112.

[0147] It should be noted that the flat portion 111 can be relatively flat relative to the raised portion 112. The flat portion 111 can also have a smooth arc surface. The raised portion 112 can have an upward inclined angle relative to the horizontal plane. The raised portion 112 can extend upward in an arc surface.

[0148] In some possible implementation manners, referring to Figure 2 and Figure 3 As shown, along the length direction X of the vehicle 10, the length of the cushion bracket 120 is greater than or equal to 0.4 times and less than or equal to 0.6 times the length of the cushion body 110.

[0149] In the embodiments of the present application, when the ratio of the length of the cushion support 120 to the length of the cushion body 110 is less than 0.4, the contact area of the cushion support 120 with the cushion body 110 in the length direction X of the vehicle 10 is small, which easily affects the support strength of the cushion support 120 to the cushion body 110. When the ratio of the length of the cushion support 120 to the length of the cushion body 110 is greater than 0.6, the length of the cushion support 120 extending in the length direction X of the vehicle 10 is too large. In particular, when the rear end of the cushion body 110 has the raised portion 112, the length of the cushion support 120 extending is too long, which easily causes the cushion support 120 to be exposed when the vehicle 10 is viewed in the width direction Y of the vehicle 10, affecting the suspension effect of the cushion body 110 and the aesthetic appearance.

[0150] In addition, it is easily understood that the axis of the outer cylinder 133 is close to the front end of the cushion body 110. The greater the length of the cushion support 120 extending to the raised portion 112 in the length direction X of the vehicle 10, the longer the support arm of the cushion support 120, which easily affects the support reliability of the cushion support 120 to the cushion body 110.

[0151] Therefore, by setting the ratio of the length of the cushion support 120 to the length of the cushion body 110 to be greater than or equal to 0.4 and less than or equal to 0.6, the above technical problems can be effectively solved.

[0152] In some examples, the length of the cushion body 110 is greater than or equal to 250 mm and less than or equal to 350 mm, which is not limited in the embodiments of the present application. The length of the cushion body 110 can be set according to the size of the adult ischium to meet the comfort and safety of most adults.

[0153] In some realizable manners, as shown in Figure 4 In some realizable manners, as shown in

[0154] In the embodiments of the present application, when the ratio of the width of the cushion support 120 to the maximum width of the cushion body 110 is less than 0.1, the contact area of the cushion support 120 with the cushion body 110 in the width direction Y of the vehicle 10 is small, which easily affects the support strength of the cushion support 120 to the cushion body 110. When the ratio of the width of the cushion support 120 to the maximum width of the cushion body 110 is greater than 0.3, the size of the cushion support 120 is too wide, which easily causes the weight of the whole vehicle to increase and causes redundant design for the support effect. Therefore, by setting the ratio of the width of the cushion support 120 to the maximum width of the cushion body 110 to be greater than or equal to 0.1 and less than or equal to 0.3, the above technical problems can be effectively solved.

[0155] In some examples, the width of the cushion body 110 can be greater than or equal to 200 mm and less than or equal to 350 mm, which is not limited in the embodiments of the present application. The width of the cushion body 110 can be set according to the size of the adult ischium to meet the comfort and safety of most adults.

[0156] Referring to Figures 5 to 11 As shown in the drawings, the embodiments of the present application provide a cushion assembly 100 applied to a vehicle 10. The cushion assembly 100 can include a cushion body 110, a cushion support 120 and a damping mechanism 130.

[0157] The cushion support 120 is arranged at the bottom of the cushion body 110. The cushion support 120 is used to support the cushion body 110. The damping mechanism 130 includes an inner part 131, a damping layer 132 and an outer cylinder 133. The outer cylinder 133 extends along the width direction Y of the vehicle 10, and along the radial direction of the outer cylinder 133, the damping layer 132 is located between the inner part 131 and the outer cylinder 133.

[0158] Among them, one of the inner part 131 and the outer cylinder 133 is connected with the cushion support 120, and the other of the inner part 131 and the outer cylinder 133 is used to be connected with the frame 200 of the vehicle 10.

[0159] In the embodiments of the present application, the damping layer 132 of the damping mechanism 130 can be used to absorb the acting force of the relative rotation between the inner part 131 and the outer cylinder 133, so that when one of them rotates, the other can remain relatively stable by the elastic deformation of the damping layer 132, so that the cushion body 110 can remain relatively stable, thereby relieving the impact force in the bumpy road conditions, and improving the riding safety and comfort of the rider.

[0160] In some examples, the inner part 131, the damping layer 132 and the outer cylinder 133 can be concentrically arranged.

[0161] In some realizable ways, referring to Figure 6 and Figure 7 As shown in the drawings, the inner part 131 of the embodiments of the present application includes an inner cylinder 1311 and an inner shaft 1312. Along the radial direction of the outer cylinder 133, the inner shaft 1312, the inner cylinder 1311, the damping layer 132 and the outer cylinder 133 are sequentially arranged, and the inner shaft 1312 and the inner cylinder 1311 are an integral structure.

[0162] In the embodiments of the present application, the inner shaft 1312 can be used to be connected with one of the cushion support 120 or the frame 200. The outer cylinder 133 can be used to be connected with the other of the cushion support 120 or the frame 200. The inner cylinder 1311 can be sleeved on the outside of the inner shaft 1312. The damping layer 132 can fill the gap between the inner cylinder 1311 and the outer cylinder 133.

[0163] The inner shaft body 1312 and the inner cylinder body 1311 are in an integrated structure. The outer wall of the inner shaft body 1312 can be attached to the inner cylinder body 1311, so that the two can move synchronously. For example, when the inner shaft body 1312 rotates, the inner cylinder body 1311 rotates synchronously, so that the part of the shock-absorbing layer 132 attached to the inner cylinder body 1311 can be deformed. The part of the shock-absorbing layer 132 away from the inner cylinder body 1311 can remain relatively static, so that the outer cylinder body 133 can remain relatively static.

[0164] In some examples, the inner shaft body 1312 and the inner cylinder body 1311 in an integrated structure can mean that the inner shaft body 1312 and the inner cylinder body 1311 form a structure that is not easy to disassemble. The inner shaft body 1312 can fill the internal space of the inner cylinder body 1311, so that the two can stably move synchronously. For example, one of the inner shaft body 1312 and the inner cylinder body 1311 can be processed and formed, and then the other one can be secondarily formed to form an integrated structure. Alternatively, the inner shaft body 1312 and the inner cylinder body 1311 can be processed and formed at one time, which is not limited in the embodiments of the present application.

[0165] In some realizable ways, referring to FIG. 13, Figures 8 to 10 The inner part 131 of the embodiment of the present application includes an inner cylinder body 1311 and an inner shaft body 1312. The inner cylinder body 1311 is sleeved on the outside of part of the inner shaft body 1312. The inner shaft body 1312 is fixedly connected with the inner cylinder body 1311 through a shaft sleeve 134. The inner shaft body 1312 and the inner cylinder body 1311 have a hollow part 130a therebetween.

[0166] In the embodiment of the present application, the inner cylinder body 1311 and the inner shaft body 1312 can be in a split structure. At least part of the shaft sleeve 134 can be located between the inner shaft body 1312 and the inner cylinder body 1311 along the radial direction of the outer cylinder body 133, so that the inner shaft body 1312 and the inner cylinder body 1311 can move synchronously. The hollow part 130a between the inner shaft body 1312 and the inner cylinder body 1311 can reduce the overall weight of the shock-absorbing mechanism 130, which is conducive to realizing the lightweight design of the seat cushion assembly 100.

[0167] In some examples, the inner shaft body 1312 can be connected with the seat cushion support 120 or the frame 200 through the shaft sleeve 134. The inner shaft body 1312 can be provided with a shaft sleeve 134 near each end along the axial direction of the outer cylinder body 133. The shaft sleeves 134 at the two ends can form a hollow part 130a therebetween.

[0168] In some examples, the inner shaft body 1312 and the inner cylinder body 1311 move synchronously, and the inner shaft body 1312 and the inner cylinder body 1311 are in a split structure. Therefore, the through hole on the inner cylinder body 1311 for the inner shaft body 1312 to pass through can be a special-shaped hole 100b. Since the inner cylinder body 1311 and the inner shaft body 1312 are connected through the shaft sleeve 134, the shaft sleeve 134 can have a special-shaped part 1341 matching the shape of the special-shaped hole 100b. During installation, the inner shaft body 1312 can be first passed through the inside of the shaft sleeve 134. Then, the special-shaped part 1341 of the shaft sleeve 134 is inserted into the special-shaped hole 100b of the inner cylinder body 1311. Through the cooperation of the special-shaped part 1341 and the special-shaped hole 100b, the inner shaft body 1312 and the inner cylinder body 1311 can move synchronously. In other words, the inner shaft body 1312 and the inner cylinder body 1311 are not easy to rotate relative to each other.

[0169] In some examples, the special-shaped hole 100b can refer to that the cross-sectional shape of the special-shaped hole 100b is a polygon, an ellipse, etc. In the embodiments of the present application, no limitation is made. The cross section can refer to a plane perpendicular to the axis of the outer cylinder body 133.

[0170] In some examples, when the inner part 131 is connected with the cushion support 120, the inner shaft body 1312 can be connected with the cushion support 120 through the shaft sleeve 134. The mounting hole on the cushion support 120 for connecting with the shaft sleeve 134 can also be a special-shaped hole 100b. The special-shaped hole 100b can cooperate with the special-shaped part 1341 of the shaft sleeve 134 to prevent the shaft sleeve 134 from rotating relative to the cushion support 120.

[0171] In some realizable ways, referring to FIG. 13, Figure 8 As shown in the figure, the inner part 131 of the present application is fixedly connected with the cushion support 120. The outer cylinder body 133 is fixedly connected with the frame 200.

[0172] In the embodiments of the present application, when the inner part 131 is connected with the cushion support 120 and the outer cylinder body 133 is connected with the frame 200, if a bumpy road condition is encountered, the frame 200 moves up and down. The outer cylinder body 133 connected with the frame 200 rotates. Since the damping layer 132 is arranged between the inner part 131 and the outer cylinder body 133, the damping layer 132 deforms under the rotation of the outer cylinder body 133. The damping layer 132 can keep the inner part 131 inside it relatively stable, so that the cushion support 120 connected with the inner part 131 can remain stable, and thus the cushion body 110 connected with the cushion support 120 can also remain stable. The rider is not easy to feel the bumpiness on the bumpy road, which is conducive to improving the comfort, safety and experience of riding.

[0173] The inner part 131 can be directly connected with the seat cushion support 120, or can be connected through other structures, which is not limited in the embodiment. Similarly, the outer cylinder 133 can be connected with the frame 200 through a support, or can be connected through other structures, which is not limited in the embodiment.

[0174] In some possible implementation manners, referring to Figures 8 to 10 The seat cushion assembly 100 of the embodiment of the application further includes a support 150. The support 150 is connected with the frame 200. The outer cylinder 133 is connected with the support 150.

[0175] In the embodiment of the application, the support 150 can be used to connect the outer cylinder 133 and the frame 200. The frame 200, the support 150 and the outer cylinder 133 can move synchronously. When encountering a bumpy road condition, the frame 200 floats up and down and drives the outer cylinder 133 to move synchronously through the support 150. The outer cylinder 133 can rotate around its own axis. The shock-absorbing layer 132 is located between the outer cylinder 133 and the inner cylinder 1311, and therefore, through the deformation of the shock-absorbing layer 132, the inner cylinder 1311 can be kept relatively fixed when the outer cylinder 133 rotates. Since the inner cylinder 1311 moves synchronously with the inner shaft 1312, and the inner shaft 1312 is fixedly connected with the seat cushion support 120, when encountering a bumpy road condition, the seat cushion support 120 can be kept relatively stable, so that the seat cushion body 110 can be kept stable.

[0176] In some examples, an adapter 140 can be arranged between the support 150 and the shock-absorbing mechanism 130. The adapter 140 can be used to connect the support 150 and the outer cylinder 133 of the shock-absorbing mechanism 130. The adapter 140 can improve the installation convenience of the support 150 and the shock-absorbing mechanism 130.

[0177] Exemplarily, the adapter 140 can be a cylindrical structure. The adapter 140 can be sleeved on the outside of the outer cylinder 133. The adapter 140 and the outer cylinder 133 can be in interference fit. Alternatively, the adapter 140 and the outer cylinder 133 can be an integral structure.

[0178] The outer wall of the adapter 140 can be provided with at least one mounting surface for abutting with the support 150. The mounting surface and the support 150 can abut with each other, so as to improve the connection reliability of the adapter 140 and the support 150.

[0179] In some examples, the support 150 can be connected with the frame 200 in a manner of welding, riveting, locking, and the like, but is not limited thereto. The support 150 and the adapter 140 can be detachably connected through a locking piece.

[0180] In some possible implementation manners, referring to Figure 8 andFigure 9 As shown, the support 150 of the embodiment of the present application can be an integral structure.

[0181] In the embodiment of the present application, the support 150 can be used to connect the damping mechanism 130 and the frame 200. By setting the support 150 as an integral structure, the assembly parts can be reduced, the structure of the vehicle 10 can be simplified, and the aesthetic appearance of the vehicle 10 can be improved. In addition, the material maintenance cost can also be reduced.

[0182] In some examples, the support 150 can include a first plate body 151 and a second plate body 152 connected together. The first plate body 151 can be used to connect with the frame 200. The second plate body 152 can be used to connect with the damping mechanism 130. For example, the second plate body 152 can be connected with the damping mechanism 130 through the adapter 140.

[0183] For example, the first plate body 151 and the second plate body 152 can have an included angle therebetween. For example, the support 150 can be L-shaped. The first plate body 151 and the frame 200 can be fixed through welding, riveting, locking fastener connection, etc. The adapter 140 and the second plate body 152 can be detachably connected through a locking fastener.

[0184] In some implementable manners, referring to Figures 5 to 7 As shown, the inner part 131 of the embodiment of the present application is fixedly connected with the frame 200. The outer cylinder 133 is fixedly connected with the cushion bracket 120.

[0185] In the embodiment of the present application, when the inner part 131 is connected with the frame 200 and the outer cylinder 133 is connected with the cushion bracket 120, when encountering a bumpy road condition, the frame 200 moves up and down. The inner part 131 connected with the frame 200 can rotate around the axis of the outer cylinder 133. Since the damping layer 132 is arranged between the inner part 131 and the outer cylinder 133, the damping layer 132 deforms under the rotating action of the inner part 131. The outer cylinder 133 outside the damping layer 132 can remain relatively stable, so that the cushion bracket 120 connected with the outer cylinder 133 can remain stable, and then the cushion body 110 connected with the cushion bracket 120 can also remain stable. The rider is not easy to feel the bumpiness on the bumpy road, which is conducive to improving the comfort, safety and experience of riding.

[0186] In some implementable manners, referring to Figures 5 to 7 As shown, the cushion assembly 100 of the embodiment of the present application further includes a support 150. The damping mechanism 130 is connected with the frame 200 through the support 150. The outer cylinder 133 is connected with the cushion body 110.

[0187] In the embodiments of the present application, the support 150 can be used to connect the inner shaft body 1312 and the frame 200. The frame 200, the support 150, the inner shaft body 1312 and the inner cylinder body 1311 can move synchronously. When encountering a bumpy road condition, the frame 200 floats up and down and drives the inner shaft body 1312 to move synchronously through the support 150. The inner shaft body 1312 and the inner cylinder body 1311 can rotate synchronously around their own axes. The shock-absorbing layer 132 is located between the outer cylinder body 133 and the inner cylinder body 1311, so that through the deformation of the shock-absorbing layer 132, the outer cylinder body 133 can be kept relatively fixed when the inner cylinder body 1311 rotates. Since the outer cylinder body 133 is fixedly connected with the cushion bracket 120, when encountering a bumpy road condition, the cushion bracket 120 can be kept relatively stable, so that the cushion body 110 can be kept stable.

[0188] In some examples, the cushion bracket 120 can include a first side wall 121 and a second side wall 122 arranged opposite along the width direction Y of the vehicle 10. The partial shock-absorbing mechanism 130 can be located between the first side wall 121 and the second side wall 122.

[0189] In some examples, a connector 140 for connecting with the shock-absorbing mechanism 130 can be arranged between the first side wall 121 and the second side wall 122. The connector 140 can be sleeved on the outside of the outer cylinder body 133, and the connector 140 and the outer cylinder body 133 can be in interference fit.

[0190] Exemplarily, along the width direction Y of the vehicle 10, one end of the connector 140 is connected with the first side wall 121, and the other end of the connector 140 is connected with the second side wall 122. The connector 140 and the shock-absorbing mechanism 130 can be arranged concentrically. The two ends of the inner shaft body 1312 of the shock-absorbing mechanism 130 can pass through the two ends of the connector 140 for connecting with the support 150.

[0191] In some realizable modes, referring to Figure 7 The support 150 of the embodiments of the present application includes a first bracket 153 and a second bracket 154. The first bracket 153 and the second bracket 154 are arranged opposite along the width direction Y of the vehicle 10. The first bracket 153 and the second bracket 154 are respectively connected with the two ends of the inner shaft body 1312.

[0192] In the embodiments of the present application, the first bracket 153 and the second bracket 154 can be respectively used to connect with the two ends of the inner shaft body 1312. The first bracket 153 and the second bracket 154 can provide stable support for the two ends of the inner shaft body 1312, so as to improve the connection stability of the shock-absorbing mechanism 130 and the frame 200, so that when encountering a bumpy road condition, the shock-absorbing mechanism 130 can buffer the bumping impact force, so as to improve the riding comfort and safety.

[0193] The first support 153 and the second support 154 can be not connected. One end of the first support 153 is connected with one end of the inner shaft body 1312, and the other end of the first support 153 is connected with the frame 200. One end of the second support 154 is connected with the other end of the inner shaft body 1312, and the other end of the second support 154 is connected with the frame 200.

[0194] In some examples, the first support 153 and the second support 154 can be respectively provided with special-shaped holes 100b. The inner shaft body 1312 can be provided with a special-shaped part 1341 for cooperating with the special-shaped hole 100b. The cooperation of the special-shaped part 1341 and the special-shaped hole 100b can prevent the inner shaft body 1312 from rotating relative to the support 150.

[0195] In some examples, the first support 153 and the frame 200 can be detachably connected. The second support 154 and the frame 200 can be detachably connected.

[0196] In some examples, the first support 153 and the frame 200 can be detachably connected. The second support 154 and the frame 200 can be detachably connected. Figure 8 Figure 11 In some examples, one of the cushion support 120 and the frame 200 is provided with a limiting part 160. When the limiting part 160 is connected with the other one of the cushion support 120 and the frame 200, the cushion body 110 has a spacing with the rear fender 500 of the vehicle 10 and / or the frame 200.

[0197] In the embodiment, when encountering a bumpy road, the frame 200 floats up and down, so that the cushion body 110 and the frame 200 are close to or away from each other. The limiting part 160 can be used to constrain the maximum angle of relative rotation between the inner part 131 and the outer part, so as to constrain the minimum distance between the frame 200 and the cushion body 110, so that the cushion body 110 and the rear fender 500 of the vehicle 10 and / or the frame 200 are not easy to collide.

[0198] It is easy to understand that when the cushion body 110 collides with at least one of the rear fender 500 or the frame 200, the rear fender 500 or the frame 200 will exert a reaction force on the cushion body 110, so that the rider will feel a vibration, which will affect the riding experience. In addition, the collision between the cushion body 110 and the rear fender 500 or the frame 200 is easy to cause the deformation of the rear fender 500 or the frame 200.

[0199] ​The limiting member 160 can be arranged on the seat cushion support 120. In a normal riding state, the limiting member 160 and the frame 200 can have a spacing in the height direction Z of the vehicle 10. When the limiting member 160 contacts the frame 200 when encountering a bumpy road, the seat cushion body 110 and the rear fender 500 have a spacing, and the seat cushion body 110 and the frame 200 also have a spacing.

[0200] Alternatively, the limiting member 160 can also be arranged on the frame 200. In a normal riding state, the limiting member 160 and the seat cushion support 120 can have a spacing in the height direction Z of the vehicle 10. When the limiting member 160 contacts the seat cushion support 120 when encountering a bumpy road, the seat cushion body 110 and the rear fender 500 have a spacing, and the seat cushion body 110 and the frame 200 also have a spacing.

[0201] In some examples, the limiting member 160 can be a columnar structure. The axial direction of the limiting member 160 can be the same as the width direction Y of the vehicle 10. The two ends of the limiting member 160 can be connected with the first side wall 121 and the second side wall 122, respectively.

[0202] In some realizable modes, as shown in Figure 6 , Figure 8 and Figure 11 the seat cushion support 120 and the frame 200 of the embodiment of the present application are provided with a buffer member 170.

[0203] When the limiting member 160 is arranged on the seat cushion support 120, at least part of the buffer member 170 is located between the limiting member 160 and the frame 200 in the height direction Z of the vehicle 10. Alternatively, when the limiting member 160 is arranged on the frame 200, at least part of the buffer member 170 is located between the limiting member 160 and the seat cushion support 120 in the height direction Z of the vehicle 10.

[0204] In the embodiment of the present application, under bumpy road conditions, the buffer member 170 can be used to buffer the impact force between the limiting member 160 and the frame 200 or between the limiting member 160 and the seat cushion support 120, so that rigid collision between the limiting member 160 and the frame 200 or between the limiting member 160 and the seat cushion support 120 is not easy to occur, thereby reducing the possibility of causing the rider to feel the vibration caused by the rigid collision, affecting the riding safety and comfort.

[0205] In some realizable modes, as shown in Figure 3 one of the seat cushion support 120 and the support member 150 of the embodiment of the present application is provided with a limiting member 160. When the limiting member 160 is connected with the other of the seat cushion support 120 and the support member 150, the seat cushion body 110 has a spacing with the rear fender 500 and / or the frame 200 of the vehicle 10.

[0206] In this embodiment, the support member 150 may be disposed on the vehicle frame 200.

Alternatively, when the limiting member 160 is disposed on the support member 150, at least a portion of the buffer member 170 is located between the limiting member 160 and the seat cushion support 120 along the height direction Z of the vehicle 10.

[0209] In this embodiment of the application, under bumpy road conditions, the buffer 170 can be used to buffer the impact force between the limiting member 160 and the support member 150 or between the limiting member 160 and the seat support 120, so that rigid collisions are less likely to occur between the limiting member 160 and the frame 200 or between the limiting member 160 and the seat support 120, thereby reducing the vibration sensation caused by rigid collisions to the rider and the possibility of affecting riding safety and comfort.

[0212] In the embodiments of this application, see Figure 8 As shown, when the support member 150 is disposed on the surface of the frame 200 facing the seat support 120, the buffer member 170 can also be disposed on the support member 150 in the area corresponding to the limiting member 160, thereby preventing a rigid connection between the limiting member 160 and the frame 200 or the support member 150 through the buffer member 170. See Figure 11As shown, when the limiting member 160 is arranged on the side of the cushion support 120 facing the vehicle frame 200, the buffer member 170 can be arranged on the self structure of the limiting member 160.

And / or, the buffer member 170 is arranged on the surface of the vehicle frame 200 facing the limiting member 160, and the buffer member 170 is arranged opposite to the limiting member 160.

[0216] In the embodiments of the present application, the buffer member 170 can be arranged on both ends of the limiting member 160. In other words, the buffer member 170 can not necessarily be arranged on the entire limiting member 160.
