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 the congested urban traffic and save time and effort.

[0003] As a component 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 alleviate the impact force caused by bumpy road conditions. However, the buffering generated by the spring deformation is relatively linear, and the riding experience is not good when the road conditions are complex. Moreover, the spring repeatedly rebounds after being shaken and needs a certain time to attenuate, and the buffering effect is limited.

[0005] Therefore, a spring and a rotating shaft combination need to be added. However, the addition of the spring and the rotating shaft combination requires multiple installation points to be set, which will occupy the vehicle component arrangement space and increase the demand for frame mounting positions, and the exposed spring affects the appearance. CONTENT OF THE INVENTION

[0006] 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.

[0007] In one aspect, the present application provides a seat cushion assembly, comprising:

[0008] a seat cushion body;

[0009] 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;

[0010] a damping mechanism, at least part of the damping mechanism being located below the front side area of the seat cushion body along the length direction of the vehicle, 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;

[0011] 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.

[0012] The cushion assembly provided in the application can be used to absorb the relative rotation force between the inner part and the outer cylinder, so that when one of them rotates, the other can remain relatively stable, so that the cushion body can remain relatively stable, thereby relieving the impact force caused by the bumping in the bumpy road conditions, improving the riding safety and comfort of the rider.

[0013] Specifically, one of the inner part and the outer cylinder of the damping mechanism is connected with the cushion bracket, 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 cushion bracket. When encountering bumpy road conditions, 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 provided 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 remain relatively stable, so that the cushion bracket connected with the outer cylinder can remain stable, and the cushion body connected with the cushion bracket can also remain stable. The damping layer can absorb the bumping caused by the bumpy road conditions by deforming itself to buffer the bumping impact force, so that the rider is less likely to feel the bumping, thereby improving the comfort, safety and experience of riding.

[0014] It is easy to understand that the damping mechanism is connected with the cushion bracket through one of the inner part and the outer cylinder, and connected with the cushion body through the other, so that the damping mechanism has fewer mounting points, and the damping mechanism does not easily occupy a large internal space between the cushion body and the frame, thereby making the vehicle more beautiful and simple.

[0015] 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 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 beauty of the vehicle can also be improved.

[0016] In addition, along the length direction of the vehicle, at least part of the damping mechanism can be located in the front side area below the cushion body, so that the damping mechanism can occupy a smaller space in the rear side area below the cushion body, or even can not occupy the rear side area below the cushion body, so that the rear side area of the cushion body can be suspended on the frame, thereby improving the simplicity and beauty of the vehicle.

[0017] According to one embodiment of the application, along the length direction of the vehicle, the cushion body is adjustably mounted on the cushion bracket, so as to adjust the distance between the cushion body and the handlebar of the vehicle.

[0018] In the embodiments of the present application, the cushion body is adjustable relative to the cushion support, so that the rider can adjust the distance between the cushion body and the handlebar according to the own needs, thereby meeting the riding comfort of different height groups and different riding posture requirement groups.

[0019] Specifically, for a tall rider, the cushion body can be adjusted to move away from the handlebar to increase the distance between the handlebar and the cushion body. For a relatively short rider, the cushion body can be adjusted to move close to the handlebar to reduce the distance between the handlebar and the cushion body.

[0020] According to an embodiment of the present application, one of the cushion body and the cushion support is provided with an adjusting hole extending along the length direction of the vehicle, and the other of the cushion body and the cushion support is provided with an adjusting member which can be arranged in the adjusting hole, and the adjusting member is slidably connected to the adjusting hole for adjusting the relative position of the cushion body relative to the cushion support.

[0021] In the embodiments of the present application, the adjusting hole can form a slide for the adjusting member to slide, so that the cushion body moves along the length direction or the backward direction of the vehicle without being easily deviated to the width direction or other directions during the adjustment of the cushion body, thereby ensuring that the cushion body can be located in the middle region of the width direction of the vehicle to ensure the stability and comfort during the riding.

[0022] According to an embodiment of the present application, a plane perpendicular to the width direction of the vehicle is defined as a first projection plane, at least part of the projection of the damping mechanism on the first projection plane is located below the projection of the cushion body on the first projection plane, and along the length direction of the vehicle, the rear edge of the projection of the damping mechanism on the first projection plane does not exceed the front 1 / 3 of the projection of the cushion body on the first projection plane.

[0023] In the embodiments of the present application, at least part of the projection of the damping mechanism on the first projection plane is located below the projection of the cushion body on the first projection plane, so that the at least part of the damping mechanism can be shielded by the cushion body. Moreover, by setting the rear edge of the projection of the damping mechanism on the first projection plane does not exceed the front 1 / 3 of the projection of the cushion body on the first projection plane, the at least 2 / 3 region of the rear side of the cushion body can be free of the damping mechanism. The at least 2 / 3 region of the rear side of the cushion body can be in a floating state, which is conducive to realizing the neatness and aesthetics of the vehicle.

[0024] According to one embodiment of the present application, a plane perpendicular to the width direction of the vehicle is defined as a first projection plane, and the projection of the axis of the outer cylinder on the first projection plane does not exceed the front 1 / 4 of the projection of the seat cushion body on the first projection plane along the length direction of the vehicle.

[0025] In the embodiments of the present application, by setting the projection of the axis of the outer cylinder on the first projection plane to not exceed the front 1 / 4 of the projection of the seat cushion body on the first projection plane, the shock-absorbing mechanism can be close to the front end of the seat cushion body, so that the area of the seat cushion body at the rear has a spacing along the height direction of the vehicle from the frame, and thus the area of the seat cushion body at the rear can be in a floating state, which is beneficial to improving the aesthetic appearance of the vehicle.

[0026] According to one embodiment of the present application, the orthographic projection of the seat cushion support is located inside the orthographic projection of the seat cushion body along the height direction of the vehicle.

[0027] In the embodiments of the present application, since the seat cushion body is adjustable relative to the seat cushion support along the length direction of the vehicle, by setting the orthographic projection of the seat cushion body along the height direction of the vehicle to be located inside the orthographic projection of the seat cushion body along the height direction of the vehicle, when the position of the seat cushion body relative to the seat cushion support is adjusted, the front end of the seat cushion support will not exceed the front end of the seat cushion body, and the rear end of the seat cushion support will also not exceed the rear end of the seat cushion body.

[0028] It is easy to understand that when the orthographic projection of the seat cushion support exceeds the orthographic projection of the seat cushion body, on the one hand, when the vehicle is viewed from above along the height direction of the vehicle, the seat cushion support is exposed to the line of sight of the rider, which is not conducive to the aesthetic appearance of the vehicle. On the other hand, the rider is likely to come into contact with the seat cushion support during the riding process. Since the seat cushion support is usually a rigid structure, the rider's contact with the rigid seat cushion support is likely to affect the comfort during the riding process. Therefore, by setting the orthographic projection of the seat cushion support to be located inside the orthographic projection of the seat cushion body, the above technical problems can be effectively solved.

[0029] According to one embodiment of the present application, the bottom of the seat cushion body is provided with a recess, the recess extends along the length direction of the vehicle, and at least part of the seat cushion support is located in the recess.

[0030] In the embodiments of the present application, during the assembly of the seat cushion body and the seat cushion support, the recess of the seat cushion body can provide a preliminary positioning function for the seat cushion support. When part of the seat cushion support is located in the recess, it is easier to correspond the adjusting member with the adjusting hole, which is beneficial to realizing the rapid installation of the seat cushion body and the seat cushion support.

[0031] And, since the recess can extend along the length direction of the vehicle, when adjusting the position of the seat cushion body relative to the frame, the recess provides a guide function for the relative movement of the seat cushion body and the seat cushion support, so that the seat cushion body can move along the length direction of the vehicle. And when the rider changes the riding posture, the cooperation of the recess and the seat cushion support can increase the stability of the seat cushion body relative to the whole vehicle, improve the service life of the seat cushion support and the adjusting piece, and improve the riding experience.

[0032] According to an embodiment of the present application, along the length direction of the vehicle, the recess has a first end and a second end, the first end is closer to the front end of the seat cushion body relative to the second end;

[0033] The first end is located on the side of the seat cushion support towards the front end of the seat cushion body; and / or,

[0034] The seat cushion support is located on the side of the second end towards the front end of the seat cushion body.

[0035] In the embodiments of the present application, by setting the first end of the recess on the side of the seat cushion support towards the front end of the seat cushion body, when adjusting the sliding of the seat cushion body along the length direction of the vehicle, the front end of the seat cushion support will not exceed the first end of the recess, so that the front end of the seat cushion support will not exceed the front end of the seat cushion body, thereby not easily affecting the appearance of the vehicle, nor easily causing the rider to contact the rigid seat cushion support.

[0036] By setting the seat cushion support on the side of the second end towards the front end of the seat cushion body, when adjusting the sliding of the seat cushion body along the length direction of the vehicle, the rear end of the seat cushion support will not exceed the second end of the recess, so that the rear end of the seat cushion support will not exceed the rear end of the seat cushion body, thereby not easily affecting the appearance of the vehicle, nor easily causing the rider to contact the rigid seat cushion support.

[0037] In addition, along the length direction of the vehicle, when the rear side area of the seat cushion body is raised, by setting the rear end of the seat cushion support not to exceed the second end of the recess, the distance between the rear end of the seat cushion support and the raised area of the rear side of the seat cushion body along the height direction of the vehicle can be reduced, which reduces the contact area between the seat cushion support and the seat cushion body, and reduces the possibility of affecting the supporting effect of the seat cushion support on the seat cushion body. And when the vehicle is viewed from the width direction of the vehicle, the area of the seat cushion support exposed to the recess is large, which is not conducive to the appearance of the vehicle.

[0038] According to an embodiment of the present application, the length of the recess along the length direction of the vehicle is greater than or equal to the sum of the length of the adjusting hole and the length of the seat cushion support.

[0039] In the embodiment of the present application, the length of the adjusting hole extends along the length direction of the vehicle, and the length of the adjusting hole can restrict the range of adjustment of the seat cushion body relative to the seat cushion support, so that the seat cushion body has two limit positions along the length direction of the vehicle. During the adjustment of the seat cushion body, the seat cushion support and the seat cushion body have relative movement. When the seat cushion body is at the two limit positions, the front end of the seat cushion support is located in the recess, and the rear end of the seat cushion support is also located in the recess, in other words, the front end of the seat cushion support will not exceed the first end of the recess, and the rear end of the seat cushion support will not exceed the second end of the recess.

[0040] According to an embodiment of the present application, along the width direction of the vehicle, the width dimension of the recess matches the width dimension of the seat cushion support.

[0041] In the embodiment of the present application, along the width direction of the vehicle, by matching the width dimension of the recess with the width dimension of the seat cushion support, the recess can limit the seat cushion support in the width direction, so that when the rider turns or leans, the seat cushion body is less likely to shake through the cooperation of the recess and the seat cushion support, thereby improving the stability and safety of the rider during riding.

[0042] According to an embodiment of the present application, the bottom of the seat cushion body is further provided with a reinforcing portion, and at least one side of the recess is provided with the reinforcing portion along the width direction of the vehicle.

[0043] In the embodiment of the present application, the reinforcing portion can be used to improve the strength of the seat cushion body to provide more stable support for the rider. The recess and the reinforcing portion can be used together to improve the strength of the seat cushion body to provide safe and stable support during riding.

[0044] According to an embodiment of the present application, along the length direction of the vehicle, the seat cushion body includes a flat portion and a raised portion, the flat portion is located on the front side of the raised portion, the seat cushion support is arranged on the flat portion, and at least part of the seat cushion support extends to the raised portion.

[0045] In the embodiment of the present application, the raised portion can be raised upward relative to the flat portion. Through the raised portion, the surface of the seat cushion body in contact with the rider can be fitted to the physiological curve of the ischium, so that the seat cushion body can uniformly disperse the gravity of the rider, and relieve or even eliminate fatigue during long-time riding. Moreover, when the riding is accelerated or climbing, the raised portion 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 hip.

[0046] At least part of the raised portion can be kept in a suspended state due to the upward raising of the raised portion relative to the flat portion. By extending the at least part of the seat cushion support to the raised portion, the at least part of the seat cushion support can support the raised portion, so as to improve the support effect of the raised portion on the rider.

[0047] Especially, when the seat cushion body is formed by an injection molding process, and the at least part of the seat cushion support extends to the raised portion, the at least part of the seat cushion support can be attached to the raised portion, so as to support part of the raised portion.

[0048] According to an embodiment of the present application, the ratio of the length of the seat cushion support to the seat cushion body along the length direction of the vehicle is greater than or equal to 0.4 and less than or equal to 0.6.

[0049] When the ratio of the length of the seat cushion support to the seat cushion body is less than 0.4, the contact area of the seat cushion support and the seat cushion body along the length direction of the vehicle is small, which can affect the support strength of the seat cushion support on the seat cushion body. When the ratio of the length of the seat cushion support to the seat cushion body is greater than 0.6, the length of the seat cushion support extending along the length direction of the vehicle is too large. Especially, when the rear end of the seat cushion body has a raised portion, the length of the seat cushion support extending is too long, which can cause the seat cushion support to be exposed when the vehicle is viewed from the width direction of the vehicle, affecting the suspension effect of the seat cushion body and the aesthetic appearance.

[0050] It is easy to understand that the axis of the outer cylinder body is close to the front end of the seat cushion body. The greater the length of the seat cushion support extending to the raised portion along the length direction of the vehicle, the longer the support arm of the seat cushion support, which can affect the support reliability of the seat cushion support on the seat cushion body.

[0051] Therefore, by setting the ratio of the length of the seat cushion support to the seat cushion body 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.

[0052] According to an embodiment of the present application, the ratio of the width of the seat cushion support to the maximum width of the seat cushion body along the width direction of the vehicle is greater than or equal to 0.1 and less than or equal to 0.3.

[0053] In this embodiment, when the ratio of the width of the seat cushion bracket to the maximum width of the seat cushion body is less than 0.1, the contact area between the seat cushion bracket and the seat cushion body is small along the width direction of the vehicle, which can easily affect the support strength of the seat cushion bracket for the seat cushion body. When the ratio of the width of the seat cushion bracket to the maximum width of the seat cushion body is greater than 0.3, the seat cushion bracket is too wide, which can easily lead to an increase in the weight of the entire vehicle and cause redundant design for the support effect. Therefore, by setting the ratio of the width of the seat cushion bracket to the maximum width of the seat cushion body to be greater than or equal to 0.1 and less than or equal to 0.3, the above-mentioned technical problems can be effectively solved.

[0054] On the other hand, this application provides a vehicle that includes a frame and a seat cushion assembly as described in any of the above embodiments. The seat cushion assembly is disposed on the frame.

[0055] In addition to the technical problems solved by the embodiments of the present invention, the technical features constituting the technical solutions, and the beneficial effects brought about by the technical features of these technical solutions as described above, other technical problems that can be solved by the seat cushion assembly and vehicle 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 embodiments.

[0089] The specific embodiments of the present application have been shown and described in the above-described drawings, and will be described in more detail hereinafter. These drawings and detailed description are not intended to limit the scope of the present application concept in any way, but to illustrate the present application concept to those skilled in the art by referring to specific embodiments. DETAILED DESCRIPTION

[0090] The exemplary embodiments will be described in detail herein with reference to the attached drawings. In the following description, the same numbers are used to indicate the same or similar components. The embodiments described in the following exemplary embodiments are not meant to represent 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 apparent that the described embodiments are a part of, not all, embodiments consistent with the present application. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present application.

[0091] 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. Moreover, the vehicle can be an electric vehicle. The present application will be described taking a motorcycle as an example. The motorcycle can be an electric motorcycle.

[0092] 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.

[0093] 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 a 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. Therefore, a spring and a rotating shaft combination need to be added. However, the addition of the spring and the rotating shaft combination requires multiple installation points to be arranged, which occupies the layout space of the vehicle components and increases the demand for frame mounting positions, and the exposed spring affects the appearance.

[0094] Based on the above technical problems, the applicant improves the structure of the existing seat cushion assembly. In the embodiment of the present application, the damping mechanism includes an inner part, a damping layer and an outer cylinder. When encountering a bumpy road condition, the vehicle frame vibrates, and the outer cylinder or the inner part connected with the vehicle frame can rotate. When one of the outer cylinder and the inner part rotates, because the damping layer is between the outer cylinder and the inner part, the damping layer can absorb the vibration generated by the rotation by deforming itself to buffer the bumping feeling. Therefore, the other of the outer cylinder and the inner part can be relatively stable, so that the seat cushion body can be relatively stable, and the rider on the seat cushion body is not easy to feel the bumping feeling, which is beneficial to improve the riding experience.

[0095] The seat cushion assembly 100 and the vehicle 10 provided by the present application are described below with reference to the accompanying drawings and in combination with specific embodiments.

[0096] Referring to Figures 1 to 6 The seat cushion assembly 100 of the embodiment of the present application includes a seat cushion body 110, a seat cushion support 120 and a damping mechanism 130.

[0097] The seat cushion support 120 is arranged at the bottom of the seat cushion body 110. The seat cushion support 120 is used to support the seat cushion body 110. Along the length direction X of the vehicle 10, at least part of the damping mechanism 130 is located in the front side area below the seat cushion body 110. It should be noted that the front side area below the seat cushion body 110 can refer to the area of the front 1 / 2 of the seat cushion body 110 in the length direction X of the vehicle 10.

[0098] 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.

[0099] Among them, one of the inner part 131 and the outer cylinder 133 is connected with the seat cushion support 120. The other of the inner part 131 and the outer cylinder 133 is used to be connected with the vehicle frame 200 of the vehicle 10.

[0100] 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 seat cushion body 110 can remain relatively stable, thereby relieving the impact force caused by the bumping when the road condition is bumpy, and improving the riding safety and comfort of the rider.

[0101] Specifically, one of the inner part 131 and the outer cylinder 133 of the damping mechanism 130 is connected with the seat cushion support 120, and the other is connected with the frame 200. For example, the inner part 131 is connected with the frame 200, and the outer cylinder 133 is connected with the seat cushion support 120. When encountering a bumpy road, 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. Because the damping layer 132 is arranged between the inner part 131 and the outer cylinder 133, the damping layer 132 deforms under the action of the rotation of the inner part 131. For example, the inner wall of the damping layer 132 that is in contact with the inner part 131 can move synchronously with the inner part 131, and the outer wall of the damping layer 132 that is in contact with 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 seat cushion support 120 connected with the outer cylinder 133 can remain stable, and then the seat cushion body 110 connected with the seat cushion support 120 can also remain stable. The damping layer 132 can absorb the bump caused by the bumpy road through its own deformation to buffer the bumping impact force, so that the rider is not easy to feel the bumping feeling, thereby improving the comfort, safety and experience of riding.

[0102] In some examples, the damping layer 132 can have a cylindrical structure. The inner wall of the damping layer 132 is in contact with the inner part 131. The outer wall of the damping layer 132 is in contact with the outer cylinder 133. When the inner part 131 rotates, the inner wall of the damping layer 132 can rotate synchronously with the inner part 131. Because the damping layer 132 can elastically deform, the outer wall of the damping layer 132 can remain relatively stationary, so that the outer cylinder 133 connected with 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 elastically deform, the inner wall of the damping layer 132 can remain relatively stationary, so that the inner part 131 connected with the inner wall can remain relatively stable.

[0103] It is easy to understand that the damping mechanism 130 is connected with the seat cushion support 120 through one of the inner part 131 and the outer cylinder 133, and is connected with the seat cushion body 110 through the other of the inner part 131 and the outer cylinder 133. Therefore, the damping mechanism 130 has fewer mounting points, and the damping mechanism 130 is not easy to occupy the relatively large internal space between the seat cushion body 110 and the frame 200, so that the vehicle 10 is more beautiful and simple as a whole.

[0104] Especially, when the vehicle 10 is a hard-tail vehicle 10, the rear wheel 400 of the vehicle 10 is directly and rigidly fixed to the tail of the frame 200, and the tail of the frame 200 is a whole rigid structure. Through the damping mechanism 130 of the embodiment, on the one hand, a better damping effect of the hard-tail vehicle 10 can be achieved, and the riding experience can be improved. On the other hand, the appearance of the vehicle 10 can also be improved.

[0105] In addition, along the length direction X of the vehicle 10, at least part of the damping mechanism 130 can be located in the front area below the seat cushion body 110. Therefore, the damping mechanism 130 can occupy a smaller space in the rear area below the seat cushion body 110, or even can not occupy the rear area below the seat cushion body 110, so that the rear area of the seat cushion body 110 can be suspended on the frame 200, thereby improving the minimalism and appearance of the vehicle 10.

[0106] In some examples, the material of the damping layer 132 can be a damping material, for example, rubber. The damping layer 132 of the damping material can convert the vibration and bumping feeling into internal potential energy through internal friction, so as to reduce the impact of the bumping feeling transmitted to the rider's body.

[0107] In some realizable manners, referring to Figure 1 As shown, along the length direction X of the vehicle 10, the seat cushion body 110 is adjustably mounted on the seat cushion support 120, so as to adjust the distance between the seat cushion body 110 and the handlebar 300 of the vehicle 10.

[0108] In the embodiment, the seat cushion body 110 is adjustable relative to the seat cushion support 120. Therefore, the rider can adjust the distance between the seat cushion body 110 and the handlebar 300 according to the own needs, so as to meet the riding comfort of different height groups and different riding posture requirement groups.

[0109] Specifically, for a tall rider, the seat cushion body 110 can be adjusted to move away from the handlebar 300, so as to increase the distance between the handlebar 300 and the seat cushion body 110. For a relatively short rider, the seat cushion body 110 can be adjusted to move close to the handlebar 300, so as to reduce the distance between the handlebar 300 and the seat cushion body 110.

[0110] In some realizable manners, referring to Figure 4 As shown, one of the seat cushion body 110 and the seat cushion support 120 of the embodiment is provided with an adjusting hole 100a extending along the length direction X of the vehicle 10. The other of the seat cushion body 110 and the seat 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 seat cushion body 110 relative to the seat cushion support 120.

[0111] In the embodiment, the adjusting hole 100a can form a sliding channel for the adjusting member 101 to slide in, so that the cushion body 110 moves along the length direction X or the backward direction of the vehicle 10 without being easily deviated to the width direction Y or other directions during the adjustment of the cushion body 110, so as to ensure that the cushion body 110 is located in the middle region of the width direction Y of the vehicle 10, thereby ensuring the stability and comfort during the riding.

[0112] In addition, the position of the cushion body 110 relative to the frame 200 is adjusted by sliding the adjusting member 101 in the adjusting hole 100a, which is simple and convenient for the rider to operate.

[0113] It should be noted that the adjusting member 101 can be protrudingly arranged below the cushion body 110. The adjusting hole 100a extending along the length direction X of the vehicle 10 can be arranged on the cushion support 120. Alternatively, the adjusting hole 100a extending along the length direction X of the vehicle 10 can be arranged on the bottom of the cushion body 110. The adjusting member 101 protruding towards the cushion body 110 can be arranged on the cushion support 120. The embodiment is not limited in this regard.

[0114] In some examples, the cushion body 110 and the cushion support 120 can be locked by the locking member.

[0115] Exemplarily, the adjusting member 101 can be a screw structure. The locking member can be a nut.

[0116] In some realizable manners, referring to FIGS. 1, 2 and 3, Figure 2 and Figure 3 The plane perpendicular to the width direction Y of the vehicle 10 is defined as the first projection plane. At least part of the projection of the damping mechanism 130 on the first projection plane is located below the projection of the cushion body 110 on the first projection plane, and the rear edge of the projection of the damping mechanism 130 on the first projection plane does not exceed the front 1 / 3 of the projection of the cushion body 110 on the first projection plane along the length direction X of the vehicle 10.

[0117] In the embodiment, at least part of the projection of the damping mechanism 130 on the first projection plane is located below the projection of the cushion body 110 on the first projection plane, so that the at least part of the damping mechanism 130 can be shielded by the cushion body 110. In addition, by setting the rear edge of the projection of the damping mechanism 130 on the first projection plane does not exceed the front 1 / 3 of the projection of the cushion body 110 on the first projection plane, the at least 2 / 3 region of the rear side of the cushion body 110 can be free of the damping mechanism 130. The at least 2 / 3 region of the rear side of the cushion body 110 can be in a floating state, which is conducive to realizing the neatness and aesthetics of the vehicle 10.

[0118] In some examples, the at least partial shock-absorbing mechanism 130 can be located between the seat cushion body 110 and the frame 200 along the height direction Z of the vehicle 10.

[0119] 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.

[0120] In some examples, the seat cushion body 110 can shield the shock-absorbing mechanism 130 when the rider looks down at the vehicle 10 along the height direction Z of the vehicle 10.

[0121] In some examples, the seat cushion support 120 can have an internal space for accommodating the at least partial shock-absorbing mechanism 130. The seat cushion support 120 can shield the at least partial shock-absorbing mechanism 130. For example, the shock-absorbing mechanism 130 can be shielded in the internal space of the seat cushion support 120 when the rider looks at the vehicle 10 along the width direction Y of the vehicle 10.

[0122] In some implementable manners, 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.

[0123] In the embodiments of the present application, by arranging the projection of the axis of the outer cylinder 133 on the first projection plane to not exceed the front 1 / 4 of the projection of the seat cushion body 110 on the first projection plane, the shock-absorbing mechanism 130 can be close to the front end of the seat cushion body 110, so that the area of the seat cushion body 110 at the rear has a spacing along the height direction Z of the vehicle 10 from the frame 200, and thus the area of the seat cushion body 110 at the rear can be in a floating state, which is conducive to improving the aesthetic appearance of the vehicle 10.

[0124] It should be noted that the front end in the embodiments of the present application refers to the area close to the front wheel along the length direction X of the vehicle 10.

[0125] In some implementable manners, referring to Figure 3 and Figure 4 , along the height direction Z of the vehicle 10, the orthographic projection of the seat cushion support 120 is located inside the orthographic projection of the seat cushion body 110.

[0126] In the embodiment of the present application, since the cushion body 110 is adjustable along the length direction X of the vehicle 10 on the cushion support 120, by setting the orthogonal projection of the cushion body 110 along the height direction Z of the vehicle 10 in the orthogonal projection of the cushion body 110 along the height direction Z of the vehicle 10, when adjusting the position of the cushion body 110 relative to the cushion support 120, the front end of the cushion support 120 will not exceed the front end of the cushion body 110, and the rear end of the cushion support 120 will not exceed the rear end of the cushion body 110.

[0127] It is easy to understand that when the orthogonal projection of the cushion support 120 exceeds the orthogonal projection of the cushion body 110, on the one hand, when looking down on the vehicle 10 along the height direction Z of the vehicle 10, the cushion support 120 is exposed to the line of sight of the rider, which is not conducive to the aesthetics of the vehicle 10. On the other hand, the rider is easy to contact with the cushion support 120 during the riding process. Since the cushion support 120 is usually a rigid structure. The rider contacting with the rigid cushion support 120 can easily affect the comfort during the riding process. Therefore, by setting the orthogonal projection of the cushion support 120 in the orthogonal projection of the cushion body 110, the above technical problems can be effectively solved.

[0128] In some realizable ways, referring to Figures 4 to 6 It is shown that the bottom of the cushion body 110 of the embodiment of the present application is provided with a recessed part 110a. The recessed part 110a extends along the length direction X of the vehicle 10. At least part of the cushion support 120 is located in the recessed part 110a.

[0129] In the embodiment of the present application, during the assembly of the cushion body 110 and the cushion support 120, the recessed part 110a of the cushion body 110 can provide a preliminary positioning function for the cushion support 120. When part of the cushion support 120 is located in the recessed part 110a, the adjusting part 101 can be more easily corresponded with the adjusting hole 100a, which is conducive to realizing the rapid installation of the cushion body 110 and the cushion support 120.

[0130] And since the recessed part 110a can extend along the length direction X of the vehicle 10, when adjusting the position of the cushion body 110 relative to the frame 200, the recessed part 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. And when the riding posture of the rider changes, the cooperation of the recessed part 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 part 101, and improve the riding experience.

[0131] Specifically, when adjusting the distance between the seat cushion body 110 and the handlebar 300, the locking member on the adjusting member 101 can be loosened first. The adjusting member 101 can slide in the adjusting hole 100a. Then, the recess 110a and the seat cushion support 120 can cooperate with each other to make the seat cushion body 110 and the seat cushion support 120 move relative to each other along the length direction X of the vehicle 10.

[0132] In some examples, the surfaces of the seat cushion body 110 and the seat cushion support 120 relative to each other along the height direction Z of the vehicle 10 can be flat. Exemplarily, the bottom wall of the recess 110a and the surface of the seat cushion support 120 towards the seat cushion body 110 can be in close contact with each other, so as to increase the contact area of the seat cushion support 120 and the seat cushion body 110, so that the seat cushion support 120 can provide stable support for the seat cushion body 110.

[0133] In some realizable ways, referring to Figure 4 and Figure 5 It is shown that the recess 110a of the embodiment of the 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 seat cushion body 110 relative to the second end 1102. The first end 1101 is located on the side of the seat cushion support 120 towards the front end of the seat cushion body 110. And / or, the seat cushion support 120 is located on the side of the second end 1102 towards the front end of the seat cushion body 110.

[0134] In the embodiment of the application, by setting the first end 1101 of the recess 110a on the side of the seat cushion support 120 towards the front end of the seat cushion body 110, when adjusting the seat cushion body 110 to slide along the length direction X of the vehicle 10, the front end of the seat cushion support 120 will not exceed the first end 1101 of the recess 110a, so that the front end of the seat cushion support 120 will not exceed the front end of the seat cushion body 110, thereby not easily affecting the appearance of the vehicle 10, nor easily making the rider contact the rigid seat cushion support 120.

[0135] By setting the seat cushion support 120 on the side of the second end 1102 towards the front end of the seat cushion body 110, when adjusting the seat cushion body 110 to slide along the length direction X of the vehicle 10, the rear end of the seat cushion support 120 will not exceed the second end 1102 of the recess 110a, so that the rear end of the seat cushion support 120 will not exceed the rear end of the seat cushion body 110, thereby not easily affecting the appearance of the vehicle 10, nor easily making the rider contact the rigid seat cushion support 120.

[0136] In addition, along the length direction X of the vehicle 10, when the rear side region 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 that the rear end of the cushion support 120 and the region of the rear side of the cushion body 110 raised have a spacing along the height direction Z of the vehicle 10, resulting in a reduction in the contact area of the cushion support 120 with the cushion body 110, affecting the supporting 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 region of the cushion support 120 exposed to the recessed portion 110a is larger, which is not conducive to the aesthetics of the vehicle 10.

[0137] In some implementable manners, the length of the recessed portion 110a 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.

[0138] 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 have relative movement. When the cushion body 110 is at 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.

[0139] It is easy to understand that the two limit positions can respectively refer to that the cushion body 110 and the handlebar 300 have the smallest spacing, and the cushion body 110 and the handlebar 300 have the largest spacing.

[0140] In some implementable manners, referring to Figure 4 As shown, along the width direction Y of the vehicle 10, the width dimension of the recessed portion 110a matches the width dimension of the cushion support 120.

[0141] In the embodiment of the present application, along the width direction Y of the vehicle 10, by setting the width dimension of the recessed portion 110a to match the width dimension of the cushion support 120, the recessed portion 110a can limit the cushion support 120 in the width direction Y, so that the cushion body 110 is not easy to shake when turning or leaning, thereby improving the stability and safety of the rider during riding.

[0142] In some examples, the recess 110a can have two inner walls opposite along the width direction Y of the vehicle 10. The two inner walls and the cushion support 120 can be mutually constrained. When viewing the vehicle 10 along the width direction Y of the vehicle 10, the two inner walls of the recess 110a can shield part of the cushion support 120, which is conducive to improving the aesthetics of the vehicle 10.

[0143] In some implementable manners, referring to Figures 4 to 6 The bottom of the cushion body 110 of the embodiment of the present application is also provided with a reinforcing portion 110b. At least one side of the recess 110a is provided with the reinforcing portion 110b along the width direction Y of the vehicle 10.

[0144] In the embodiment of the present application, the reinforcing portion 110b can be used to improve the strength of the cushion body 110, so as to provide more stable support for the rider. The recess 110a and the reinforcing portion 110b can be used together to improve the strength of the cushion body 110, so as to provide safe and stable support during riding.

[0145] In some examples, the reinforcing portion 110b can be but is not limited to a recess, a protrusion, a reinforcing rib or the like structure, which is not limited in the embodiment of the present application.

[0146] In some examples, the recess 110a can be arranged close to the middle along the width direction Y of the vehicle 10. At least one side of the recess 110a is provided with the reinforcing portion 110b. For example, both sides of the recess 110a can be provided with the reinforcing portion 110b.

[0147] In some implementable manners, referring to Figure 2 and Figure 3 The cushion body 110 includes a flat portion 111 and a raised portion 112 along the length direction X of the vehicle 10. The flat portion 111 is located at the front side of the raised portion 112. The cushion support 120 is arranged on the flat portion 111, and at least part of the cushion support 120 extends to the raised portion 112.

[0148] In the embodiment of the present application, the raised portion 112 can be raised upward relative to the flat portion 111. Through the raised portion 112, the surface of the cushion body 110 in contact with the rider can be fitted 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. Moreover, when accelerating or climbing, 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.

[0149] At least part of the raised portion 112 can be kept in a suspended state due to the upward raising of the raised portion 112 relative to the flat portion 111. By arranging the at least part of the seat cushion support 120 to extend towards the raised portion 112, the at least part of the seat cushion support 120 can support the raised portion 112 to improve the support effect of the raised portion 112 on the rider.

[0150] In particular, when the seat cushion body 110 is formed by an injection molding process, the at least part of the seat cushion support 120 extends to the raised portion 112, and the at least part of the seat cushion support 120 can be in close contact with the raised portion 112 to support part of the raised portion 112.

[0151] 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 upwardly inclined angle relative to the horizontal plane. The raised portion 112 can extend upwardly in an arc shape.

[0152] In some possible implementations, as shown in Figure 2 and Figure 3 The ratio of the length of the seat cushion support 120 to the length of the seat cushion body 110 along the length direction X of the vehicle 10 is greater than or equal to 0.4 and less than or equal to 0.6.

[0153] In the embodiments of the present application, when the ratio of the length of the seat cushion support 120 to the length of the seat cushion body 110 is less than 0.4, the contact area of the seat cushion support 120 with the seat cushion body 110 along the length direction X of the vehicle 10 is small, which can affect the support strength of the seat cushion support 120 on the seat cushion body 110. When the ratio of the length of the seat cushion support 120 to the length of the seat cushion body 110 is greater than 0.6, the length of the seat cushion support 120 extending along the length direction X of the vehicle 10 is too large. In particular, when the rear end of the seat cushion body 110 has the raised portion 112, the length of the seat cushion support 120 extending is too long, which can cause the seat cushion support 120 to be exposed when the vehicle 10 is viewed along the width direction Y of the vehicle 10, affecting the suspension effect of the seat cushion body 110 and the aesthetic appearance.

[0154] In addition, it can be easily understood that the axis of the outer cylinder 133 is close to the front end of the seat cushion body 110. The greater the length of the seat cushion support 120 extending towards the raised portion 112 along the length direction X of the vehicle 10, the longer the support arm of the seat cushion support 120, which can affect the support reliability of the seat cushion support 120 on the seat cushion body 110.

[0155] Therefore, by arranging the ratio of the length of the seat cushion support 120 to the length of the seat 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.

[0156] In some examples, the length of the seat 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 seat cushion body 110 can be set according to the size of the adult ischium to meet the comfort and safety of most adults.

[0157] In some realizable manners, referring to Figure 4 As shown in the figure, along the width direction Y of the vehicle 10, the ratio of the width of the seat cushion support 120 to the maximum width of the seat cushion body 110 is greater than or equal to 0.1 and less than or equal to 0.3.

[0158] In the embodiments of the present application, when the ratio of the width of the seat cushion support 120 to the maximum width of the seat cushion body 110 is less than 0.1, along the width direction Y of the vehicle 10, the contact area of the seat cushion support 120 and the seat cushion body 110 is small, which is easy to affect the support strength of the seat cushion support 120 to the seat cushion body 110. When the ratio of the width of the seat cushion support 120 to the maximum width of the seat cushion body 110 is greater than 0.3, the size of the seat cushion support 120 is too wide, which is easy to increase the weight of the whole vehicle and cause redundant design to the support effect. Therefore, by setting the ratio of the width of the seat cushion support 120 to the maximum width of the seat 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.

[0159] In some examples, the width of the seat 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 seat cushion body 110 can be set according to the size of the adult ischium to meet the comfort and safety of most adults.

[0160] Referring to Figures 5 to 11 As shown in the figure, the present application provides a seat cushion assembly 100 applied to a vehicle 10. The seat cushion assembly 100 can include a seat cushion body 110, a seat cushion support 120 and a damping mechanism 130.

[0161] The seat cushion support 120 is arranged at the bottom of the seat cushion body 110. The seat cushion support 120 is used to support the seat 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.

[0162] Among them, one of the inner part 131 and the outer cylinder 133 is connected with the seat 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.

[0163] In this embodiment, the shock-absorbing layer 132 of the shock-absorbing mechanism 130 can be used to absorb the force of relative rotation between the inner component 131 and the outer cylinder 133. When one of them rotates, the shock-absorbing layer 132 generates elastic deformation, so that the other can remain relatively stable. This allows the seat body 110 to remain relatively stable, thereby reducing the impact force on bumpy roads and improving the rider's riding safety and comfort.

[0164] In some examples, the inner component 131, the damping layer 132, and the outer cylinder 133 can be arranged concentrically.

[0165] See also some of the possible implementation methods. Figure 6 and Figure 7 As shown, the internal component 131 in this embodiment 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 arranged sequentially, and the inner shaft 1312 and the inner cylinder 1311 are an integral structure.

[0166] In this embodiment, the inner shaft 1312 can be connected to either the seat support 120 or the frame 200. The outer cylinder 133 can be connected to the other of the seat support 120 or the frame 200. The inner cylinder 1311 can be fitted over the inner shaft 1312. The damping layer 132 can fill the gap between the inner cylinder 1311 and the outer cylinder 133.

[0167] The inner shaft 1312 and the inner cylinder 1311 are an integral structure. The outer wall of the inner shaft 1312 can be fitted against the inner cylinder 1311 so that they can move synchronously. For example, when the inner shaft 1312 rotates, the inner cylinder 1311 rotates synchronously, so that the portion of the damping layer 132 that is fitted against the inner cylinder 1311 can deform. The portion of the damping layer 132 away from the inner cylinder 1311 can remain relatively stationary, thereby allowing the outer cylinder 133 to remain relatively stationary.

[0168] In some examples, the inner shaft 1312 and the inner cylinder 1311 being an integral structure can mean that the inner shaft 1312 and the inner cylinder 1311 form a structure that is not easily disassembled. The inner shaft 1312 can fill the internal space of the inner cylinder 1311 so that the two can move stably and synchronously. For example, after one of the inner shaft 1312 and the inner cylinder 1311 is formed, it can be formed together with the other in a secondary molding process to form an integral structure. Alternatively, the inner shaft 1312 and the inner cylinder 1311 can also be formed in one step, which is not limited in the embodiments of this application.

[0169] See also some of the possible implementation methods. Figures 8 to 10As shown, the inner part 131 of the embodiment of the present application comprises an inner cylinder 1311 and an inner shaft 1312. The inner cylinder 1311 is sleeved on the outer portion of the inner shaft 1312. The inner shaft 1312 is fixedly connected with the inner cylinder 1311 through a shaft sleeve 134. The hollow portion 130a is formed between the inner shaft 1312 and the inner cylinder 1311.

[0170] In the embodiment of the present application, the inner cylinder 1311 and the inner shaft 1312 can be a split structure. At least part of the shaft sleeve 134 can be located between the inner shaft 1312 and the inner cylinder 1311 along the radial direction of the outer cylinder 133, so that the inner shaft 1312 and the inner cylinder 1311 can move synchronously. The hollow portion 130a between the inner shaft 1312 and the inner cylinder 1311 can reduce the overall weight of the damping mechanism 130, which is conducive to the lightweight design of the seat cushion assembly 100.

[0171] In some examples, the inner shaft 1312 can be connected with the seat cushion support 120 or the frame 200 through the shaft sleeve 134. The inner shaft 1312 can be provided with a shaft sleeve 134 near each end along the axial direction of the outer cylinder 133. The shaft sleeves 134 at the two ends can form the hollow portion 130a.

[0172] In some examples, the inner shaft 1312 and the inner cylinder 1311 move synchronously, and the inner shaft 1312 and the inner cylinder 1311 are a split structure. Therefore, the through hole for the inner shaft 1312 to pass through on the inner cylinder 1311 can be a special-shaped hole 100b. Since the inner cylinder 1311 and the inner shaft 1312 are connected through the shaft sleeve 134, the shaft sleeve 134 can have a special-shaped portion 1341 matching the shape of the special-shaped hole 100b. During installation, the inner shaft 1312 can be first passed through the inside of the shaft sleeve 134. Then, the special-shaped portion 1341 of the shaft sleeve 134 is inserted into the special-shaped hole 100b of the inner cylinder 1311. Through the cooperation of the special-shaped portion 1341 and the special-shaped hole 100b, the inner shaft 1312 and the inner cylinder 1311 can move synchronously. In other words, the inner shaft 1312 and the inner cylinder 1311 are not easy to rotate relative to each other.

[0173] The special-shaped hole 100b can refer to a polygonal, elliptical, or the like cross-sectional shape of the special-shaped hole 100b. In the embodiment of the present application, no limitation is made. The cross section can refer to a plane perpendicular to the axis of the outer cylinder 133.

[0174] 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 for connecting with the shaft sleeve 134 on the cushion support 120 can also be a special-shaped hole 100b. The special-shaped hole 100b can be matched with the special-shaped part 1341 of the shaft sleeve 134, so that the shaft sleeve 134 and the cushion support 120 are not easy to rotate relative to each other.

[0175] In some realizable modes, as shown in Figure 8 The inner part 131 of the embodiment of the application is fixedly connected with the cushion support 120. The outer cylinder body 133 is fixedly connected with the frame 200.

[0176] In the embodiment of the 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, when encountering a bumpy road condition, the frame 200 moves up and down. The outer cylinder body 133 connected with the frame 200 rotates. Because 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 be kept stable, and then the cushion body 110 connected with the cushion support 120 can also be kept 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.

[0177] Among them, the inner part 131 and the cushion support 120 can be directly connected, or can also be connected through other structures, which are not limited in the embodiment. Similarly, the outer cylinder body 133 and the frame 200 can be connected through a support, or can also be connected through other structures, which are not limited in the embodiment.

[0178] In some realizable modes, as shown in Figures 8 to 10 The cushion assembly 100 of the embodiment of the application further comprises a support 150. The support 150 is connected with the frame 200. The outer cylinder body 133 is connected with the support 150.

[0179] In the embodiments of the present application, the support 150 can be used to connect the outer cylinder 133 and the vehicle frame 200. The vehicle frame 200, the support 150 and the outer cylinder 133 can move synchronously. When encountering a bumpy road, the vehicle 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, the seat cushion support 120 can be kept relatively stable, so that the seat cushion body 110 can be kept stable.

[0180] In some examples, an adapter 140 can be provided 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.

[0181] 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 interference fit. Alternatively, the adapter 140 and the outer cylinder 133 can be an integral structure.

[0182] 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.

[0183] In some examples, the support 150 can be connected with the vehicle frame 200 by welding, riveting, locking piece connection and the like, but is not limited thereto. The support 150 and the adapter 140 can be detachably connected through a locking piece.

[0184] In some realizable modes, referring to FIGS. 1 to 3, Figure 8 and Figure 9 the support 150 of the embodiments of the present application can be an integral structure.

[0185] In the embodiments of the present application, the support 150 can be used to connect the shock-absorbing mechanism 130 and the vehicle frame 200. By setting the support 150 as an integral structure, the assembly parts can be reduced, so as to simplify the structure of the vehicle 10 and improve the aesthetic appearance of the vehicle 10. Moreover, the material maintenance cost can also be reduced.

[0186] 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.

[0187] Exemplarily, the first plate body 151 and the second plate body 152 can have an included angle therebetween. For example, the support 150 can be in an L shape. The first plate body 151 and the frame 200 can be fixedly connected through welding, riveting, locking fasteners, or the like. The adapter 140 and the second plate body 152 can be detachably connected through locking fasteners.

[0188] In some implementable manners, referring to Figures 5 to 7 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.

[0189] 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 thus the cushion body 110 connected with the cushion bracket 120 can also remain stable. The rider is less likely to feel the bumpiness on the bumpy road, which is conducive to improving the comfort, safety and experience of riding.

[0190] In some implementable manners, referring to Figures 5 to 7 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.

[0191] 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.

[0192] 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.

[0193] 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.

[0194] For example, 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.

[0195] 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.

[0196] 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.

[0197] 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.

[0198] 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.

[0199] 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.

[0200] 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, the first support 153 and the frame 200 can be detachably connected. The second support 154 and the frame 200 can be detachably connected.

[0201] 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.

[0202] 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, affecting the riding experience. Moreover, the collision between the cushion body 110 and the rear fender 500 or the frame 200 is easy to cause the rear fender 500 or the frame 200 to be deformed.

[0203] ​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.

[0204] 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.

[0205] 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.

[0206] In some realizable modes, as shown in Figure 6 、 Figure 8 and Figure 11 , at least one of the seat cushion support 120 and the frame 200 of the embodiment of the application is provided with a buffer member 170.

[0207] 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.

[0208] In the embodiment of the 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 vibration caused by rigid collision to the rider, affecting the riding safety and comfort.

[0209] 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 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.

[0210] In this embodiment, the support member 150 may be disposed on the vehicle frame 200. Along the height direction Z of the vehicle 10, the support member 150 may have a surface opposite to the seat cushion support 120. The limiting member 160 may be disposed on the seat cushion support 120, or the limiting member 160 may also be disposed on the surface of the support member 150 facing the seat cushion support 120.

[0211] In some possible implementations, at least one of the seat cushion support 120 and the support member 150 in this application embodiment is provided with a cushion member 170.

[0212] When the limiting member 160 is disposed on the seat cushion support 120, at least a portion of the buffer member 170 is located between the limiting member 160 and the support member 150 along the height direction Z of the vehicle 10. 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.

[0213] 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.

[0214] See in some examples Figure 8 As shown, when the limiting member 160 is provided on the seat cushion support 120, the buffer member 170 can be provided on the support member 150 on the frame 200. Alternatively, see... Figure 6 As shown, the buffer 170 can also be mounted on the frame 200 via the plate structure 180. This is not specifically limited in this embodiment. The buffer 170 can be, but is not limited to, being fixed to the plate structure 180 by adhesive bonding.

A buffer member 170 is disposed on the limiting member 160. And / or, the buffer member 170 is disposed on the frame 200. And / or, the buffer member 170 is disposed on the support member 150.

[0216] 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.

[0220] 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. The region of the limiting member 160 corresponding to the vehicle frame 200 is provided with the buffer member 170, so as to reduce the material cost of the buffer member 170.

[0221] In some examples, the buffer member 170 can be a buffer sleeve. The buffer sleeve can be sleeved on both ends of the limiting member 160.
