Description

Technical Field

[0001] The present application relates to the technical field of vehicles, and particularly relates to a seat cushion assembly and a vehicle. Background Art

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

[0003] As a component directly contacted by riders, the comfort of the seat cushion can directly affect the riding safety and riding experience. Especially when encountering bumpy road conditions, riders will bear continuous bumps and impacts, which are likely to cause fatigue and even lumbar spine injuries.

[0004] In the related art, a spring is provided under the seat cushion. The elastic deformation of the spring stores and releases energy to relieve the impact force caused by bumpy road conditions. However, the buffering generated by the spring deformation is relatively linear. When the road conditions are complex, the riding feeling has no damping feeling, and the spring rebounds repeatedly after being vibrated and requires a certain time to decay, so the buffering effect is limited and the riding experience is not good.

[0005] Therefore, it is necessary to add a combination of a spring and a rotating shaft. However, adding a combination of a spring and a rotating shaft requires the setting of multiple installation points, which will occupy the layout space of the vehicle components and increase the requirements for the frame installation position, and the exposed spring affects the appearance. Summary of the Invention

[0006] The present application provides a seat cushion assembly and a vehicle, which can solve the problem of poor shock absorption and buffering effect, affecting the riding experience.

[0007] On the one hand, the present application provides a seat cushion assembly, which includes:

[0008] A seat cushion body;

[0009] A seat cushion bracket, the seat cushion bracket is arranged at the bottom of the seat cushion body, and the seat cushion bracket is used to support the seat cushion body;

[0010] A shock absorption mechanism, along the length direction of the vehicle, at least part of the shock absorption mechanism is located in the front side area below the seat cushion body. The shock absorption mechanism includes an inner member, a shock absorption layer and an outer cylinder body. The outer cylinder body extends along the width direction of the vehicle. Along the radial direction of the outer cylinder body, the shock absorption layer is located between the inner member and the outer cylinder body;

[0011] Wherein, one of the inner member and the outer cylinder body is connected to the seat cushion bracket, and the other of the inner member and the outer cylinder body is used to be connected to the vehicle frame.

[0012] For the seat cushion assembly provided by this application, the shock-absorbing layer of the shock-absorbing mechanism can be used to absorb the acting force of relative rotation between the internal component and the outer cylinder, so that when one of them rotates, the other can remain relatively stable, thereby enabling the seat cushion body to remain relatively stable. Furthermore, when on bumpy roads, the impact caused by the bumps can be alleviated, improving the riding safety and comfort of the rider.

[0013] Specifically, one of the internal component and the outer cylinder of the shock-absorbing mechanism is connected to the seat cushion bracket, and the other is connected to the vehicle frame. Exemplarily, taking the internal component being connected to the vehicle frame and the outer cylinder being connected to the seat cushion bracket as an example, when encountering bumpy roads, the vehicle frame moves up and down with the uneven road surface. The internal component connected to the vehicle frame can rotate around itself. Since there is a shock-absorbing layer between the internal component and the outer cylinder, the shock-absorbing layer deforms under the rotational action of the internal component. For example, the inner wall of the shock-absorbing layer in contact with the internal component can move synchronously with the internal component, while the outer wall of the shock-absorbing layer in contact with the outer cylinder can remain relatively fixed. Therefore, through the deformation of the shock-absorbing layer, the outer cylinder can be kept relatively stable, so that the seat cushion bracket connected to the outer cylinder can be kept stable, and further the seat cushion body connected to the seat cushion bracket can also be kept stable. The shock-absorbing layer can absorb the bumpy feeling caused by bumpy roads through its own deformation to buffer the bump impact force, making it difficult for the rider to feel the bumpy feeling, which is beneficial to improving the riding comfort, safety and experience.

[0014] It is easy to understand that the shock-absorbing mechanism is connected to the seat cushion bracket through one of the internal component and the outer cylinder, and is connected to the seat cushion body through the other of the internal component and the outer cylinder. Therefore, the installation points of the shock-absorbing mechanism are fewer, and the shock-absorbing mechanism is not likely to occupy a large internal space between the seat cushion body and the vehicle frame, making the overall vehicle more beautiful and concise.

[0015] In particular, when the vehicle is a hardtail vehicle, the rear wheel of the vehicle is directly rigidly fixed to the tail of the vehicle frame, and the tail of the vehicle frame is an integral rigid structure. Through the shock-absorbing mechanism of the embodiment of this application, on the one hand, a good shock-absorbing effect of the hardtail vehicle can be achieved, improving the riding experience. On the other hand, the aesthetics of the vehicle can also be improved.

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

[0017] According to an embodiment of this application, along the length direction of the vehicle, the seat cushion body is adjustably mounted on the seat cushion bracket for adjusting the distance between the seat cushion body and the handlebar of the vehicle.

[0018] In the embodiment of the present application, the seat cushion body is adjustable relative to the seat cushion bracket. Therefore, the rider can adjust the distance between the seat cushion body and the handlebar according to his own needs, so as to meet the riding comfort requirements of people with different heights and different riding postures.

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

[0020] According to an embodiment of the present application, one of the seat cushion body and the seat cushion bracket is provided with an adjustment hole extending along the length direction of the vehicle, and the other of the seat cushion body and the seat cushion bracket is provided with an adjustment member that can pass through the adjustment hole. The adjustment member is slidably connected to the adjustment hole for adjusting the relative position of the seat cushion body relative to the seat cushion bracket.

[0021] In the embodiment of the present application, the adjustment hole can form a slideway for the adjustment member to slide, so that during the process of adjusting the seat cushion body, the seat cushion body moves along the length direction or the backward direction of the vehicle, and is not easily offset in the width direction or other directions, thereby ensuring that the seat cushion body can be located in the middle area in the width direction of the vehicle to ensure the stability and comfort during riding.

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

[0023] In the embodiment of the present application, at least part of the projection of the shock absorption mechanism on the first projection plane is located below the projection of the seat cushion body on the first projection plane. Therefore, at least part of the shock absorption mechanism can be blocked by the seat cushion body. And by setting the rear edge of the projection of the shock absorption mechanism on the first projection plane not to exceed the front 1 / 3 of the projection of the seat cushion body on the first projection plane, at least 2 / 3 of the area at the rear of the seat cushion body is not provided with a shock absorption mechanism. At least 2 / 3 of the area at the rear of the seat cushion body can be in a suspended state, which is beneficial to realizing the neatness and beauty of the vehicle.

[0024] According to an embodiment of the present application, a plane perpendicular to the width direction of the vehicle is defined as the first projection plane. Along the length direction of the vehicle, 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.

[0025] In the embodiment of the present application, by setting the projection of the axis of the outer cylinder on the first projection plane not to exceed the front 1 / 4 of the projection of the seat cushion body on the first projection plane, the shock absorption mechanism can be made closer to the front end of the seat cushion body, so that there is a spacing in the height direction of the vehicle between the rear region of the seat cushion body and the vehicle frame. Thus, the rear region of the seat cushion body can be in a suspended state, which is beneficial to improving the aesthetics of the vehicle.

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

[0027] In the embodiment of the present application, since the seat cushion body is adjustable along the length direction of the vehicle relative to the seat cushion bracket, by setting the orthographic projection of the seat cushion body along the height direction of the vehicle to be located within the orthographic projection of the seat cushion body along the height direction of the vehicle, when adjusting the position of the seat cushion body relative to the seat cushion bracket, the front end of the seat cushion bracket will not protrude beyond the front end of the seat cushion body, and the rear end of the seat cushion bracket will not protrude beyond the rear end of the seat cushion body either.

[0028] It is easy to understand that when the orthographic projection of the seat cushion bracket protrudes beyond the orthographic projection of the seat cushion body, on the one hand, when looking down at the vehicle along the height direction of the vehicle, the seat cushion bracket is exposed to the sight of the rider, which is not beneficial to the aesthetics of the vehicle. On the other hand, the rider is prone to contact with the seat cushion bracket during the riding process. Since the seat cushion bracket is usually a rigid structure, when the rider contacts the rigid seat cushion bracket, it is easy to affect the comfort during the riding process. Therefore, by setting the orthographic projection of the seat cushion bracket to be located inside the orthographic projection of the seat cushion body, the above technical problems can be effectively solved.

[0029] According to an embodiment of the present application, a recessed portion is provided at the bottom of the seat cushion body. The recessed portion extends along the length direction of the vehicle, and at least a part of the seat cushion bracket is located in the recessed portion.

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

[0031] Moreover, since the recessed portion can extend along the longitudinal direction of the vehicle, when adjusting the position of the seat cushion body relative to the vehicle frame, the recessed portion provides a guiding effect on the relative movement between the seat cushion body and the seat cushion bracket, enabling the seat cushion body to move along the longitudinal direction of the vehicle. And when the riding posture of the rider changes, the cooperation between the recessed portion and the seat cushion bracket can increase the stability of the seat cushion body relative to the whole vehicle, improve the service life of the seat cushion bracket and the adjusting member, and enhance the riding experience.

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

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

[0034] The seat cushion bracket is located on a side of the second end facing the front end of the seat cushion body.

[0035] In the embodiment of the present application, by setting the first end of the recessed portion to be located on a side of the seat cushion bracket facing the front end of the seat cushion body, when adjusting the seat cushion body to slide along the longitudinal direction of the vehicle, the front end of the seat cushion bracket will not extend beyond the first end of the recessed portion, so that the front end of the seat cushion bracket will not extend beyond the front end of the seat cushion body, and thus it is not easy to affect the aesthetics of the vehicle, nor is it easy for the rider to contact the rigid seat cushion bracket.

[0036] By setting the seat cushion bracket to be located on a side of the second end facing the front end of the seat cushion body, when adjusting the seat cushion body to slide along the longitudinal direction of the vehicle, the rear end of the seat cushion bracket will not extend beyond the second end of the recessed portion, so that the rear end of the seat cushion bracket will not extend beyond the rear end of the seat cushion body, and thus it is not easy to affect the aesthetics of the vehicle, nor is it easy for the rider to contact the rigid seat cushion bracket.

[0037] In addition, along the longitudinal direction of the vehicle, when the rear side area of the seat cushion body tilts upward, by setting the rear end of the seat cushion bracket not to extend beyond the second end of the recessed portion, it is possible to reduce the distance in the vehicle height direction between the rear end of the seat cushion bracket and the upwardly tilted area at the rear side of the seat cushion body, resulting in a decrease in the contact area between the seat cushion bracket and the seat cushion body and affecting the support effect of the seat cushion bracket on the seat cushion body. And when looking at the vehicle from the width direction of the vehicle, the area where the seat cushion bracket is exposed outside the recessed portion is relatively large, which is not conducive to the aesthetics of the vehicle.

[0038] According to an embodiment of the present application, the length of the recessed portion along the longitudinal direction of the vehicle is greater than or equal to the sum of the length of the adjustment hole and the length of the seat cushion bracket.

[0039] In the embodiments of the present application, the length of the adjustment hole extends along the length direction of the vehicle. The length of the adjustment hole can restrict the adjustment range of the seat cushion body relative to the seat cushion bracket, so that the seat cushion body has two extreme positions along the length direction of the vehicle. During the adjustment process of the seat cushion body, relative movement occurs between the seat cushion bracket and the seat cushion body. When the seat cushion body is at the two extreme positions, the front end of the seat cushion bracket is located in the recess, and the rear end of the seat cushion bracket is also located in the recess. In other words, the front end of the seat cushion bracket does not extend beyond the first end of the recess, and the rear end of the seat cushion bracket does not extend beyond 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 bracket.

[0041] In the embodiments of the present application, along the width direction of the vehicle, by setting the width dimension of the recess to match the width dimension of the seat cushion bracket, the recess can limit the seat cushion bracket in the width direction. When turning or the rider tilts during riding, through the mutual cooperation between the recess and the seat cushion bracket, the seat cushion body is not likely to shake, thereby improving the stability and safety of the rider during riding.

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

[0043] In the embodiments of the present application, the reinforcing portion can be used to improve the strength of the seat cushion body to provide a more stable support for the rider. The recess and the reinforcing portion can be jointly used 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 in front of the raised portion. The seat cushion bracket is disposed on the flat portion, and at least a part of the seat cushion bracket extends toward the raised portion.

[0045] In the embodiments 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 fit the physiological curve of the ischium, so that the seat cushion body can evenly disperse the gravity of the rider, relieve or even eliminate the fatigue during long-term riding. Moreover, when accelerating or climbing during riding, the raised portion can provide support for the rider, enabling the rider to maintain a stable posture and reducing the possibility of the buttocks sliding backward and affecting the riding smoothness.

[0046] Among them, since the warped portion warps upward relative to the flat portion, at least part of the warped portion can be kept in a suspended state. By arranging at least part of the seat cushion bracket to extend towards the warped portion, at least part of the seat cushion bracket can support the warped portion, so as to improve the support effect of the warped portion on the rider.

[0047] In particular, when the seat cushion body is formed by an injection molding process, when at least part of the seat cushion bracket extends to the warped portion, at least part of the seat cushion bracket and the warped portion can be mutually attached to support part of the warped portion.

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

[0049] In the embodiment of the present application, when the ratio of the length of the seat cushion bracket to the seat cushion body is less than 0.4, along the length direction of the vehicle, the contact area between the seat cushion bracket and the seat cushion body is small, which is likely to affect the support strength of the seat cushion bracket for the seat cushion body. When the ratio of the length of the seat cushion bracket to the seat cushion body is greater than 0.6, along the length direction of the vehicle, the extending length of the seat cushion bracket is too large. In particular, when the rear end of the seat cushion body has a warped portion, the overlong extending length of the seat cushion bracket is likely to cause the seat cushion bracket to be exposed when the vehicle is viewed from the front in the width direction of the vehicle, affecting the suspended effect of the seat cushion body and the aesthetics.

[0050] Moreover, it is easy to understand that the axis of the outer cylinder is close to the front end of the seat cushion body. Along the length direction of the vehicle, the greater the extending length of the seat cushion bracket towards the warped portion, the longer the support force arm of the seat cushion bracket, which is likely to affect the support reliability of the seat cushion bracket for the seat cushion body.

[0051] Therefore, by setting the ratio of the length of the seat cushion bracket 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, along the width direction of the vehicle, the ratio of the width of the seat cushion bracket to the maximum width of the seat cushion body is greater than or equal to 0.1 and less than or equal to 0.3.

[0053] In the embodiments of the present application, 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, along the width direction of the vehicle, the contact area between the seat cushion bracket and the seat cushion body is small, which is likely to 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 size of the seat cushion bracket is too wide, which is likely to cause an increase in the overall vehicle weight, and moreover, it results in a 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 technical problems can be effectively solved.

[0054] On the other hand, a vehicle provided by the present application includes a vehicle frame and the seat cushion assembly in any of the above embodiments. The seat cushion assembly is arranged on the vehicle frame.

[0055] In addition to the technical problems solved by the embodiments of the present invention described above, the technical features constituting the technical solutions, and the beneficial effects brought by these technical features of the technical solutions, other technical problems that can be solved by the seat cushion assembly and the vehicle provided by the embodiments of the present invention, other technical features included in the technical solutions, and the beneficial effects brought by these technical features will be further described in detail in the specific implementation manners.

[0089] Through the above - mentioned drawings, specific embodiments of the present application have been shown, and there will be a more detailed description hereinafter. These drawings and textual descriptions are not intended to limit the scope of the concept of the present application in any way, but to illustrate the concept of the present application to those skilled in the art by referring to specific embodiments. Detailed implementation manners

[0090] Here, the exemplary embodiments will be described in detail, and the examples are shown in the drawings. When the following description refers to the drawings, unless otherwise indicated, the same numerals in different drawings represent the same or similar elements. The implementation manners described in the following exemplary embodiments do not represent all implementation manners consistent with the present application. On the contrary, they are merely examples of devices and methods consistent with some aspects of the present application as detailed in the appended claims. Obviously, the described embodiments are some embodiments of the present application, rather than all embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments in the present application without creative efforts belong to the scope of protection of the present application.

[0091] The seat cushion assembly of the embodiments of the present application can be applied to vehicles. Among them, the vehicle can be a bicycle, a scooter, a motorcycle, etc. And, the vehicle can be an electric vehicle. The present application takes the vehicle as a motorcycle as an example for description. Among them, the motorcycle can be an electric motorcycle.

[0092] As a component that the rider directly contacts, the comfort of the seat cushion can directly affect the safety of riding and the riding experience. Especially when encountering bumpy road conditions, the rider will bear continuous bumps and impacts, which are likely to cause fatigue and even lumbar spine injuries.

[0093] In the related art, a spring is provided under the seat cushion. The energy is stored and released through the elastic deformation of the spring to relieve the impact force caused by bumpy road conditions. However, after being vibrated, the spring rebounds repeatedly and requires a certain time to decay, and the buffering effect is limited, and the riding experience is not good. Therefore, it is necessary to add a combination of a spring and a rotating shaft. However, adding a combination of a spring and a rotating shaft requires the setting of multiple installation points, which will occupy the layout space of the whole vehicle components and increase the requirements for the frame installation positions, and the exposed spring affects the aesthetics.

[0094] Based on the above technical problems, the applicant has improved the structure of the existing seat cushion assembly. In the embodiments of the present application, the shock absorption mechanism includes an inner member, a shock absorption layer, and an outer cylinder. When encountering a bumpy road condition, the vehicle frame vibrates, and the outer cylinder or the inner member connected to the vehicle frame can rotate. When one of the outer cylinder and the inner member rotates, since there is a shock absorption layer between the outer cylinder and the inner member, the shock absorption layer can absorb the vibration generated by the rotation through its own deformation to buffer the bumpy feeling. Therefore, the other of the outer cylinder and the inner member can be relatively stable, so that the seat cushion body can be relatively stable, and the rider on the seat cushion body is not easily affected by the bumpy feeling, which is beneficial to improving the riding experience.

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

[0096] See Figures 1 to 6 As shown, the seat cushion assembly 100 of the embodiments of the present application includes a seat cushion body 110, a seat cushion bracket 120, and a shock absorption mechanism 130.

[0097] The seat cushion bracket 120 is disposed at the bottom of the seat cushion body 110. The seat cushion bracket 120 is used to support the seat cushion body 110. Along the length direction X of the vehicle 10, at least a part of the shock absorption 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 may refer to the front 1 / 2 area of the seat cushion body 110 in the length direction X of the vehicle 10.

[0098] The shock absorption mechanism 130 includes an inner member 131, a shock absorption 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 shock absorption layer 132 is located between the inner member 131 and the outer cylinder 133.

[0099] Wherein, one of the inner member 131 and the outer cylinder 133 is connected to the seat cushion bracket 120. The other of the inner member 131 and the outer cylinder 133 is used to be connected to the vehicle frame 200 of the vehicle 10.

[0100] In the embodiments of the present application, the shock absorption layer 132 of the shock absorption mechanism 130 can be used to absorb the acting force of the relative rotation between the inner member 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, and further, when encountering a bumpy road condition, the impact force caused by the bump can be alleviated, and the riding safety and comfort of the rider can be improved.

[0101] Specifically, one of the internal member 131 and the outer cylinder 133 of the shock absorption mechanism 130 is connected to the seat cushion bracket 120, and the other is connected to the vehicle frame 200. Exemplarily, taking the internal member 131 being connected to the vehicle frame 200 and the outer cylinder 133 being connected to the seat cushion bracket 120 as an example, when encountering a bumpy road condition, the vehicle frame 200 moves up and down with the uneven road surface. The internal member 131 connected to the vehicle frame 200 can rotate around itself. Since a shock absorption layer 132 is provided between the internal member 131 and the outer cylinder 133, the shock absorption layer 132 deforms under the rotational action of the internal member 131. For example, the inner wall of the shock absorption layer 132 that fits with the internal member 131 can move synchronously with the internal member 131, while the outer wall of the shock absorption layer 132 that fits with the outer cylinder 133 can remain relatively fixed. Therefore, the relative stability of the outer cylinder 133 can be maintained through the deformation of the shock absorption layer 132, so that the seat cushion bracket 120 connected to the outer cylinder 133 can be kept stable, and further the seat cushion body 110 connected to the seat cushion bracket 120 can also be kept stable. The shock absorption layer 132 can absorb the bumpy feeling caused by the bumpy road condition through its own deformation to buffer the bumpy impact force, making it difficult for the rider to feel the bumpy feeling, thus being beneficial to improving the riding comfort, safety and experience.

[0102] In some examples, the shock absorption layer 132 can be a cylindrical structure. The inner wall of the shock absorption layer 132 fits with the internal member 131. The outer wall of the shock absorption layer 132 fits with the outer cylinder 133. When the internal member 131 rotates, the inner wall of the shock absorption layer 132 can rotate synchronously with the internal member 131. Since the shock absorption layer 132 can produce elastic deformation, the outer wall of the shock absorption layer 132 can remain relatively stationary so that the outer cylinder 133 connected to the outer wall can be kept relatively stable. Similarly, when the outer cylinder 133 rotates, the outer wall of the shock absorption layer 132 can rotate synchronously with the outer cylinder 133. Since the shock absorption layer 132 can produce elastic deformation, the inner wall of the shock absorption layer 132 can remain relatively stationary so that the internal member 131 connected to the inner wall can be kept relatively stable.

[0103] It is easy to understand that the shock absorption mechanism 130 is connected to the seat cushion bracket 120 through one of the internal member 131 and the outer cylinder 133, and is connected to the seat cushion body 110 through the other of the internal member 131 and the outer cylinder 133. Therefore, the shock absorption mechanism 130 has fewer installation points, and the shock absorption mechanism 130 is not likely to occupy a large internal space between the seat cushion body 110 and the vehicle frame 200, thus making the vehicle 10 as a whole more beautiful and concise.

[0104] 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 tail of the frame 200, and the tail of the frame 200 is an integral rigid structure. Through the shock absorption mechanism 130 of the embodiment of the present application, on the one hand, a good shock absorption effect of the hardtail vehicle 10 can be achieved, improving the riding experience. On the other hand, the aesthetics 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 shock absorption mechanism 130 can be located in the front side area below the seat cushion body 110. Therefore, the shock absorption mechanism 130 can occupy a smaller space in the rear side area below the seat cushion body 110, or even can not occupy the rear side area below the seat cushion body 110, so that the rear side area of the seat cushion body 110 can float on the frame 200, thereby improving the minimalism and aesthetics of the vehicle 10.

[0106] In some examples, the material of the shock absorption layer 132 can be a damping material. For example, rubber. The shock absorption layer 132 of the damping material can convert vibrations and bumps into internal potential energy through internal friction to reduce the impact of bumps transmitted to the rider's body.

[0107] In some realizable ways, see 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 bracket 120 for adjusting the distance between the seat cushion body 110 and the handlebar 300 of the vehicle 10.

[0108] In the embodiment of the present application, the seat cushion body 110 is adjustable relative to the seat cushion bracket 120. Therefore, the rider can adjust the distance between the seat cushion body 110 and the handlebar 300 according to his own needs, so as to meet the riding comfort requirements of people with different heights and different riding postures.

[0109] Specifically, for a tall rider, the seat cushion body 110 can be adjusted to move away from the handlebar 300 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 closer to the handlebar 300 to reduce the distance between the handlebar 300 and the seat cushion body 110.

[0110] In some realizable ways, see Figure 4 As shown, one of the seat cushion body 110 and the seat cushion bracket 120 of the embodiment of the present application is provided with an adjustment hole 100a extending along the length direction X of the vehicle 10. The other of the seat cushion body 110 and the seat cushion bracket 120 is provided with an adjustment member 101 that can pass through the adjustment hole 100a. The adjustment member 101 is slidably connected to the adjustment hole 100a for adjusting the relative position of the seat cushion body 110 relative to the seat cushion bracket 120.

[0111] In the embodiments of the present application, the adjustment hole 100a can form a slideway for the adjustment member 101 to slide, so that during the process of adjusting the seat cushion body 110, the seat cushion body 110 moves along the length direction X or the backward direction of the vehicle 10, and is not easily offset in the width direction Y or other directions, thereby ensuring that the seat cushion body 110 can be located in the middle area of the width direction Y of the vehicle 10 to ensure the stability and comfort during riding.

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

[0113] It should be noted that the adjustment member 101 can be convexly provided below the seat cushion body 110. The seat cushion bracket 120 can be provided with an adjustment hole 100a extending along the length direction X of the vehicle 10. Alternatively, the bottom of the seat cushion body 110 can be provided with an adjustment hole 100a extending along the length direction X of the vehicle 10. The seat cushion bracket 120 can be provided with an adjustment member 101 protruding towards the seat cushion body 110. It is not limited in this embodiment.

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

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

[0116] In some implementable ways, referring to Figure 2 and Figure 3 as shown, a 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 shock absorption mechanism 130 on the first projection plane is located 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 absorption 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.

[0117] In the embodiments of the present application, at least part of the projection of the shock absorption mechanism 130 on the first projection plane is located below the projection of the seat cushion body 110 on the first projection plane. Therefore, at least part of the shock absorption mechanism 130 can be blocked by the seat cushion body 110. And by setting the rear edge of the projection of the shock absorption mechanism 130 on the first projection plane not to exceed the front 1 / 3 of the projection of the seat cushion body 110 on the first projection plane, at least 2 / 3 of the area at the rear of the seat cushion body 110 can be free of the shock absorption mechanism 130. At least 2 / 3 of the area at the rear of the seat cushion body 110 can be in a suspended state, which is beneficial to realizing the neatness and beauty of the vehicle 10.

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

[0119] In some examples, the seat cushion bracket 120 may be located below the seat cushion body 110 for supporting the seat cushion body 110. The shock absorption mechanism 130 may be disposed on the seat cushion bracket 120.

[0120] In some examples, when the rider looks down at the vehicle 10 from the height direction Z of the vehicle 10, the seat cushion body 110 may block the shock absorption mechanism 130.

[0121] In some examples, the seat cushion bracket 120 may have an internal space for accommodating at least part of the shock absorption mechanism 130. The seat cushion bracket 120 may block at least part of the shock absorption mechanism 130. For example, when the rider looks directly at the vehicle 10 from the width direction Y of the vehicle 10, the shock absorption mechanism 130 may be blocked in the internal space of the seat cushion bracket 120.

[0122] In some implementable ways, referring to Figure 2 and Figure 3 as shown, a plane perpendicular to the width direction Y of the vehicle 10 is defined as the 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 setting the projection of the axis of the outer cylinder 133 on the first projection plane not to exceed the front 1 / 4 of the projection of the seat cushion body 110 on the first projection plane, the shock absorption mechanism 130 can be made closer to the front end of the seat cushion body 110, so that there is a spacing along the height direction Z of the vehicle 10 between the rear region of the seat cushion body 110 and the vehicle frame 200, so that the rear region of the seat cushion body 110 can be in a suspended state, which is beneficial to improving the aesthetics of the vehicle 10.

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

[0125] In some implementable ways, referring to 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.

[0126] In the embodiment of the present application, since the seat cushion body 110 is adjustable along the length direction X of the vehicle 10 relative to the seat cushion bracket 120, by setting the front projection of the seat cushion body 110 along the height direction Z of the vehicle 10 to be located within the front 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 protrude beyond the front end of the seat cushion body 110, and the rear end of the seat cushion bracket 120 will not protrude beyond the rear end of the seat cushion body 110 either.

[0127] It is easy to understand that when the front projection of the seat cushion bracket 120 protrudes beyond the front projection of the seat cushion body 110, on the one hand, when looking down at the vehicle 10 along the height direction Z of the vehicle 10, the seat cushion bracket 120 is exposed to the rider's sight, which is not conducive to the aesthetics of the vehicle 10. On the other hand, the rider is prone to come into contact with the seat cushion bracket 120 during the riding process. Since the seat cushion bracket 120 is usually a rigid structure. When the rider comes into contact with the rigid seat cushion bracket 120, it is likely to affect the comfort during the riding process. Therefore, by setting the front projection of the seat cushion bracket 120 to be located inside the front projection of the seat cushion body 110, the above technical problems can be effectively solved.

[0128] In some implementable ways, as shown in Figures 4 to 6 the bottom of the seat cushion body 110 of the embodiment of the present application is provided with a recess 110a. The recess 110a extends along the length direction X of the vehicle 10. At least part of the seat cushion bracket 120 is located in the recess 110a.

[0129] In the embodiment of the present application, during the assembly process of the seat cushion body 110 and the seat cushion bracket 120, the recess 110a of the seat cushion body 110 can provide a preliminary positioning function for the seat cushion bracket 120. When part of the seat cushion bracket 120 is located in the recess 110a, it is relatively easy to align the adjusting member 101 with the adjusting hole 100a, which is conducive to the rapid installation of the seat cushion body 110 and the seat cushion bracket 120.

[0130] Moreover, since the recess 110a can extend along the length direction X of the vehicle 10, when adjusting the position of the seat cushion body 110 relative to the vehicle frame 200, the recess 110a provides a guiding function for the relative movement of the seat cushion body 110 and the seat cushion bracket 120, so that the seat cushion body 110 can move along the length direction X of the vehicle 10. And when the rider's riding posture changes, the cooperation between the recess 110a and the seat cushion bracket 120 can increase the stability of the seat cushion body 110 relative to the whole vehicle, improve the service life of the seat cushion bracket 120 and the adjusting member 101, and enhance 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, so that the adjusting member 101 can slide within the adjusting hole 100a. Then, the cooperation between the recessed portion 110a and the seat cushion bracket 120 enables the seat cushion body 110 and the seat cushion bracket 120 to generate relative movement along the length direction X of the vehicle 10.

[0132] In some examples, along the height direction Z of the vehicle 10, the opposite surfaces of the seat cushion body 110 and the seat cushion bracket 120 may be flat surfaces. Exemplarily, the bottom wall of the recessed portion 110a and the surface of the seat cushion bracket 120 facing the seat cushion body 110 may be mutually attached to increase the contact area between the seat cushion bracket 120 and the seat cushion body 110, so that the seat cushion bracket 120 can provide stable support for the seat cushion body 110.

[0133] In some implementable ways, referring to Figure 4 and Figure 5 As shown, 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 seat cushion body 110 than the second end 1102. The first end 1101 is located on the side of the front end of the seat cushion bracket 120 facing the seat cushion body 110. And / or, the seat cushion bracket 120 is located on the side of the front end of the second end 1102 facing the seat cushion body 110.

[0134] 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 seat cushion bracket 120 facing the seat cushion body 110, when the seat cushion body 110 slides along the length direction X of the vehicle 10, the front end of the seat cushion bracket 120 will not extend beyond the first end 1101 of the recessed portion 110a, so that the front end of the seat cushion bracket 120 will not extend beyond the front end of the seat cushion body 110, and thus it is not easy to affect the aesthetics of the vehicle 10, nor is it easy for the rider to contact the rigid seat cushion bracket 120.

[0135] By setting the seat cushion bracket 120 to be located on the side of the front end of the second end 1102 facing the seat cushion body 110, when the seat cushion body 110 slides along the length direction X of the vehicle 10, the rear end of the seat cushion bracket 120 will not extend beyond the second end 1102 of the recessed portion 110a, so that the rear end of the seat cushion bracket 120 will not extend beyond the rear end of the seat cushion body 110, and thus it is not easy to affect the aesthetics of the vehicle 10, nor is it easy for the rider to contact the rigid seat cushion bracket 120.

[0136] In addition, along the longitudinal direction X of the vehicle 10, when the rear region of the seat cushion body 110 is upturned, by setting the rear end of the seat cushion bracket 120 not to extend beyond the second end 1102 of the recess 110a, the distance in the height direction Z of the vehicle 10 between the rear end of the seat cushion bracket 120 and the upturned region at the rear of the seat cushion body 110 can be reduced, which may lead to a decrease in the contact area between the seat cushion bracket 120 and the seat cushion body 110 and affect the support effect of the seat cushion bracket 120 on the seat cushion body 110. Moreover, when the vehicle 10 is viewed frontally in the width direction Y of the vehicle 10, the region where the seat cushion bracket 120 is exposed outside the recess 110a is relatively large, which is not conducive to the aesthetics of the vehicle 10.

[0137] In some feasible ways, the length of the recess 110a in the longitudinal direction X of the vehicle 10 in the embodiment of the present application is greater than or equal to the sum of the length of the adjustment hole 100a and the length of the seat cushion bracket 120.

[0138] In the embodiment of the present application, the length of the adjustment hole 100a extends in the longitudinal direction X of the vehicle 10. The length of the adjustment hole 100a can restrict the adjustment range of the seat cushion body 110 relative to the seat cushion bracket 120, so that the seat cushion body 110 has two extreme positions in the longitudinal direction X of the vehicle 10. During the adjustment process of the seat cushion body 110, relative movement occurs between the seat cushion bracket 120 and the seat cushion body 110. When the seat cushion body 110 is at the two extreme positions, the front end of the seat cushion bracket 120 is located in the recess 110a, and the rear end of the seat cushion bracket 120 is also located in the recess 110a. In other words, the front end of the seat cushion bracket 120 does not extend beyond the first end 1101 of the recess 110a, and the rear end of the seat cushion bracket 120 does not extend beyond the second end 1102 of the recess 110a.

[0139] It is easy to understand that the two extreme positions can respectively refer to the situation where the minimum distance exists between the seat cushion body 110 and the handlebar 300, and the situation where the maximum distance exists between the seat cushion body 110 and the handlebar 300.

[0140] In some feasible ways, as shown in Figure 4 When viewed in the width direction Y of the vehicle 10, the width dimension of the recess 110a matches the width dimension of the seat cushion bracket 120.

[0141] In the embodiment of the present application, when viewed in the width direction Y of the vehicle 10, by setting the width dimension of the recess 110a to match the width dimension of the seat cushion bracket 120, the recess 110a can limit the seat cushion bracket 120 in the width direction Y. When turning or the rider tilts during riding, through the mutual cooperation between the recess 110a and the seat cushion bracket 120, the seat cushion body 110 is not likely to shake, thereby improving the stability and safety of the rider during riding.

[0142] In some examples, the recess 110a may have two inner walls opposite to each other in the width direction Y of the vehicle 10. The two inner walls and the seat cushion bracket 120 may be mutually constrained. When looking at the vehicle 10 straight on in the width direction Y of the vehicle 10, the two inner walls of the recess 110a may shield part of the seat cushion bracket 120, which is beneficial to improving the aesthetics of the vehicle 10.

[0143] In some implementable ways, as shown in Figures 4 to 6 the bottom of the seat cushion body 110 of the embodiment of the present application is further provided with a strengthening portion 110b. Along the width direction Y of the vehicle 10, the strengthening portion 110b is provided on at least one side of the recess 110a.

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

[0145] In some examples, the strengthening portion 110b can be, but is not limited to, structures such as concave portions, convex portions, and reinforcing ribs, and is not limited in the embodiment of the present application.

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

[0147] In some implementable ways, as shown in Figure 2 and Figure 3 along the length direction X of the vehicle 10, the seat cushion body 110 includes a flat portion 111 and a warped portion 112. The flat portion 111 is located on the front side of the warped portion 112. The seat cushion bracket 120 is arranged on the flat portion 111, and at least part of the seat cushion bracket 120 extends towards the warped portion 112.

[0148] In the embodiment of the present application, the warped portion 112 can be warped upwards relative to the flat portion 111. Through the warped portion 112, the surface of the seat cushion body 110 in contact with the rider can be fitted to the physiological curve of the ischium, so that the seat cushion body 110 can evenly disperse the gravity of the rider, relieve or even eliminate fatigue during long-term riding. Moreover, when accelerating or climbing a slope during riding, the warped portion 112 can provide support for the rider, so that the rider can maintain a stable posture and reduce the possibility of the buttocks sliding backward and affecting the riding smoothness.

[0149] Among them, since the warping part 112 warps upward relative to the flat part 111, at least part of the warping part 112 can be in a suspended state. By arranging at least part of the seat cushion bracket 120 to extend towards the warping part 112, at least part of the seat cushion bracket 120 can support the warping part 112, so as to improve the supporting effect of the warping part 112 on the rider.

[0150] In particular, when the seat cushion body 110 is formed by an injection molding process, when at least part of the seat cushion bracket 120 extends to the warping part 112, at least part of the seat cushion bracket 120 and the warping part 112 can be mutually attached to support part of the warping part 112.

[0151] It should be noted that the flat part 111 can refer to being relatively flat compared to the warping part 112. The flat part 111 can also have a smooth arc surface. There can be an upwardly inclined angle between the warping part 112 and the horizontal plane. The warping part 112 can extend upward in an arc-shaped surface.

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

[0153] In the embodiment of the present application, when the ratio of the length of the seat cushion bracket 120 to the seat cushion body 110 is less than 0.4, along the length direction X of the vehicle 10, the contact area between the seat cushion bracket 120 and the seat cushion body 110 is small, which is likely to affect the supporting strength of the seat cushion bracket 120 on the seat cushion body 110. When the ratio of the length of the seat cushion bracket 120 to the seat cushion body 110 is greater than 0.6, along the length direction X of the vehicle 10, the extending length of the seat cushion bracket 120 is too large. In particular, when the rear end of the seat cushion body 110 has a warping part 112, the overlong extending length of the seat cushion bracket 120 is likely to cause the seat cushion bracket 120 to be exposed when looking at the vehicle 10 from the front in the width direction Y of the vehicle 10, affecting the suspended effect of the seat cushion body 110 and the aesthetics.

[0154] Moreover, it is easy to understand that the axis of the outer cylinder 133 is close to the front end of the seat cushion body 110. Along the length direction X of the vehicle 10, the greater the extending length of the seat cushion bracket 120 towards the warping part 112, the longer the supporting force arm of the seat cushion bracket 120, which is likely to affect the supporting reliability of the seat cushion bracket 120 on the seat cushion body 110.

[0155] Therefore, by setting the ratio of the length of the seat cushion bracket 120 to 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 ischium of an adult to meet the use comfort and safety of the vast majority of adults.

[0157] In some realizable ways, as shown in Figure 4 shown, along the width direction Y of the vehicle 10, the ratio of the width of the seat cushion bracket 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 bracket 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 between the seat cushion bracket 120 and the seat cushion body 110 is small, which is likely to affect the support strength of the seat cushion bracket 120 for the seat cushion body 110. When the ratio of the width of the seat cushion bracket 120 to the maximum width of the seat cushion body 110 is greater than 0.3, the size of the seat cushion bracket 120 is too wide, which is likely to cause an increase in the overall vehicle weight, and moreover, it results in a redundant design for the support effect. Therefore, by setting the ratio of the width of the seat cushion bracket 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 ischium of an adult to meet the use comfort and safety of the vast majority of adults.

[0160] As shown in Figures 5 to 11 shown, the embodiments of the present application provide a seat cushion assembly 100, which is applied to the vehicle 10. The seat cushion assembly 100 can include a seat cushion body 110, a seat cushion bracket 120, and a shock absorption mechanism 130.

[0161] The seat cushion bracket 120 is disposed at the bottom of the seat cushion body 110. The seat cushion bracket 120 is used to support the seat cushion body 110. The shock absorption mechanism 130 includes an inner member 131, a shock absorption 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 shock absorption layer 132 is located between the inner member 131 and the outer cylinder 133.

[0162] Wherein, one of the inner member 131 and the outer cylinder 133 is connected to the seat cushion bracket 120, and the other of the inner member 131 and the outer cylinder 133 is used to be connected to the vehicle frame 200 of the vehicle 10.

[0163] In the embodiments of the present application, the shock-absorbing layer 132 of the shock-absorbing mechanism 130 can be used to absorb the acting force of the relative rotation between the internal member 131 and the outer cylinder 133. When one of them rotates, elastic deformation is generated through the shock-absorbing layer 132, so that the other can remain relatively stable, thereby enabling the seat cushion body 110 to remain relatively stable. Furthermore, when on a bumpy road condition, the impact force can be alleviated, improving the riding safety and comfort of the rider.

[0164] In some examples, the internal member 131, the shock-absorbing layer 132, and the outer cylinder 133 can be concentrically arranged.

[0165] In some realizable ways, referring to Figure 6 and Figure 7 As shown, the internal member 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 shock-absorbing layer 132, and the outer cylinder 133 are arranged in sequence, and the inner shaft 1312 and the inner cylinder 1311 are an integral structure.

[0166] In the embodiments of the present application, the inner shaft 1312 can be used to connect to one of the seat cushion bracket 120 or the vehicle frame 200. The outer cylinder 133 can be used to connect to the other of the seat cushion bracket 120 or the vehicle frame 200. The inner cylinder 1311 can be sleeved outside the inner shaft 1312. The shock-absorbing layer 132 can fill the gap between the inner cylinder 1311 and the outer cylinder 133.

[0167] Among them, the inner shaft 1312 and the inner cylinder 1311 are an integral structure. The outer wall of the inner shaft 1312 can be attached to the inner cylinder 1311 so that the two can move synchronously. For example, when the inner shaft 1312 rotates, the inner cylinder 1311 rotates synchronously, so that the part of the shock-absorbing layer 132 attached to the inner cylinder 1311 can generate deformation. The part of the shock-absorbing layer 132 away from the inner cylinder 1311 can remain relatively stationary, so that the outer cylinder 133 can remain relatively stationary.

[0168] In some examples, the inner shaft 1312 and the inner cylinder 1311 being an integral structure may mean that the inner shaft 1312 and the inner cylinder 1311 form a structure that is not easily detachable. The inner shaft 1312 can fill the internal space of the inner cylinder 1311 so that the two can move stably synchronously. For example, after one of the inner shaft 1312 and the inner cylinder 1311 is processed and formed, it can be secondarily formed with the other to form an integral structure. Or, the inner shaft 1312 and the inner cylinder 1311 can also be processed and formed at one time, which is not limited in the embodiments of the present application.

[0169] In some realizable ways, referring to Figures 8 to 10As shown in the figure, the internal component 131 of the embodiment of the present application includes an inner cylinder 1311 and an inner shaft 1312. The inner cylinder 1311 is sleeved outside a part of the inner shaft 1312. The inner shaft 1312 is fixedly connected to the inner cylinder 1311 through a shaft sleeve 134. Wherein, there is a hollow part 130a between the inner shaft and the inner cylinder 1311.

[0170] In the embodiment of the present application, the inner cylinder 1311 and the inner shaft 1312 can be of a split structure. Along the radial direction of the outer cylinder 133, at least part of the shaft sleeve 134 can be located between the inner shaft 1312 and the inner cylinder 1311, so that the inner shaft 1312 and the inner cylinder 1311 can move synchronously. Wherein, the hollow part 130a between the inner shaft 1312 and the inner cylinder 1311 can reduce the overall weight of the shock absorption mechanism 130, which is beneficial to realizing the lightweight design of the seat cushion assembly 100.

[0171] In some examples, the inner shaft 1312 can be connected to the seat cushion bracket 120 or the vehicle frame 200 through the shaft sleeve 134. Along the axial direction of the outer cylinder 133, shaft sleeves 134 can be respectively provided in the regions of the inner shaft 1312 near the two ends. A hollow part 130a can be formed between the shaft sleeves 134 at the two ends.

[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 of a split structure. Therefore, the through hole on the inner cylinder 1311 for the inner shaft 1312 to pass through 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 part 1341 matching the shape of the special-shaped hole 100b. During the installation process, the inner shaft 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 1311. Through the cooperation and constraint between the special-shaped part 1341 and the special-shaped hole 100b, the inner shaft 1312 and the inner cylinder 1311 can move synchronously. In other words, relative rotation is not likely to occur between the inner shaft 1312 and the inner cylinder 1311.

[0173] Wherein, 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., which is not limited in the embodiment of the present application. The cross-section can refer to a plane perpendicular to the axis of the outer cylinder 133.

[0174] In some examples, when the inner member 131 is connected to the seat cushion bracket 120, the inner shaft body 1312 can be connected to the seat cushion bracket 120 through the bushing 134. The mounting hole on the seat cushion bracket 120 for connecting with the bushing 134 can also be an irregular hole 100b. The irregular hole 100b can cooperate with the irregular portion 1341 of the bushing 134 so that relative rotation between the bushing 134 and the seat cushion bracket 120 is not likely to occur.

[0175] In some implementable ways, referring to Figure 8 as shown, the inner member 131 of the embodiment of the present application is fixedly connected to the seat cushion bracket 120. The outer cylinder 133 is fixedly connected to the vehicle frame 200.

[0176] In the embodiment of the present application, when the inner member 131 is connected to the seat cushion bracket 120 and the outer cylinder 133 is connected to the vehicle frame 200, when encountering a bumpy road condition, the vehicle frame 200 moves up and down. The outer cylinder 133 connected to the vehicle frame 200 rotates. Since a shock-absorbing layer 132 is provided between the inner member 131 and the outer cylinder 133, the shock-absorbing layer 132 deforms under the rotational action of the outer cylinder 133. The shock-absorbing layer 132 can enable the inner member 131 located therein to remain relatively stable, so that the seat cushion bracket 120 connected to the inner member 131 can remain stable, and further the seat cushion body 110 connected to the seat cushion bracket 120 can also remain stable. A rider is not likely to feel a bumpy feeling on a bumpy road condition, which is beneficial to improving the riding comfort, safety and experience.

[0177] Wherein, the inner member 131 and the seat cushion bracket 120 can be directly connected, or can also be connected through other structures, which is not limited in this embodiment. Similarly, the outer cylinder 133 and the vehicle frame 200 can be connected by a bracket, or can also be connected through other structures, which is not limited in this embodiment.

[0178] In some implementable ways, referring to Figures 8 to 10 as shown, the seat cushion assembly 100 of the embodiment of the present application further includes a support member 150. The support member 150 is connected to the vehicle frame 200. The outer cylinder 133 is connected to the support member 150.

[0179] In the embodiments of the present application, the support member 150 can be used to connect the outer cylinder 133 and the vehicle frame 200. The vehicle frame 200, the support member 150, and the outer cylinder 133 can move synchronously. When encountering a bumpy road condition, the vehicle frame 200 floats up and down and drives the outer cylinder 133 to move synchronously through the support member 150. The outer cylinder 133 can rotate about its own axis. The shock-absorbing layer 132 is located between the outer cylinder 133 and the inner cylinder 1311. Therefore, through the deformation of the shock-absorbing layer 132, when the outer cylinder 133 rotates, the inner cylinder 1311 can remain relatively fixed. Since the inner cylinder 1311 moves synchronously with the inner shaft body 1312, and the inner shaft body 1312 is fixedly connected to the seat bracket 120, when encountering a bumpy road condition, the seat bracket 120 can remain relatively stable, so that the seat body 110 can remain stable.

[0180] In some examples, a transfer member 140 can be provided between the support member 150 and the shock-absorbing mechanism 130. The transfer member 140 can be used to connect the support member 150 and the outer cylinder 133 of the shock-absorbing mechanism 130. The transfer member 140 can improve the installation convenience of the support member 150 and the shock-absorbing mechanism 130.

[0181] Exemplarily, the transfer member 140 can be a cylindrical structure. The transfer member 140 can be sleeved on the outside of the outer cylinder 133. The transfer member 140 and the outer cylinder 133 can be in interference fit. Alternatively, the transfer member 140 and the outer cylinder 133 can be an integral structure.

[0182] Wherein, at least one mounting surface for fitting with the support member 150 can be provided on the outer wall of the transfer member 140. Through the mutual fitting of the mounting surface and the support member 150, the connection reliability between the transfer member 140 and the support member 150 can be improved.

[0183] In some examples, the support member 150 can be connected to the vehicle frame 200 by, but not limited to, welding, riveting, connecting with locking fasteners, etc. The support member 150 and the transfer member 140 can be detachably connected by locking fasteners.

[0184] In some realizable ways, referring to Figure 8 and Figure 9 as shown, the support member 150 in the embodiments of the present application can be an integral structure.

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

[0186] In some examples, the support member 150 may include a connected first plate body 151 and a second plate body 152. The first plate body 151 may be used to connect to the vehicle frame 200. The second plate body 152 may be used to connect to the shock absorption mechanism 130. For example, the second plate body 152 may be connected to the shock absorption mechanism 130 through an adapter 140.

[0187] Exemplarily, there may be an included angle between the first plate body 151 and the second plate body 152. For example, the support member 150 may be in an L shape. The first plate body 151 and the vehicle frame 200 may be fixed by means such as welding, riveting, or connection with fasteners. The adapter 140 and the second plate body 152 may be detachably connected by fasteners.

[0188] In some realizable ways, referring to Figures 5 to 7 as shown, the internal part 131 of the embodiment of the present application is fixedly connected to the vehicle frame 200. The outer cylinder 133 is fixedly connected to the seat bracket 120.

[0189] In the embodiment of the present application, when the internal part 131 is connected to the vehicle frame 200 and the outer cylinder 133 is connected to the seat bracket 120, when encountering a bumpy road condition, the vehicle frame 200 moves up and down. The internal part 131 connected to the vehicle frame 200 can rotate around the axis of the outer cylinder 133. Since a shock absorption layer 132 is provided between the internal part 131 and the outer cylinder 133, the shock absorption layer 132 deforms under the rotational action of the internal part 131. The shock absorption layer 132 can keep the outer cylinder 133 outside the shock absorption layer 132 relatively stable, so that the seat bracket 120 connected to the outer cylinder 133 can be kept stable, and further the seat body 110 connected to the seat bracket 120 can also be kept stable. The rider is not easily aware of the bumpy feeling on a bumpy road condition, which is beneficial to improving the riding comfort, safety, and experience.

[0190] In some realizable ways, referring to Figures 5 to 7 as shown, the seat assembly 100 of the embodiment of the present application further includes a support member 150. The shock absorption mechanism 130 is connected to the vehicle frame 200 through the support member 150. The outer cylinder 133 is connected to the seat body 110.

[0191] In the embodiments of the present application, the support member 150 can be used to connect the inner shaft body 1312 and the vehicle frame 200. The vehicle frame 200, the support member 150, the inner shaft body 1312, and the inner cylinder body 1311 can move synchronously. When encountering a bumpy road condition, the vehicle frame 200 floats up and down and drives the inner shaft body 1312 to move synchronously through the support member 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. Therefore, through the deformation of the shock-absorbing layer 132, when the inner cylinder body 1311 rotates, the outer cylinder body 133 can remain relatively fixed. Since the outer cylinder body 133 is fixedly connected to the seat cushion bracket 120, when encountering a bumpy road condition, the seat cushion bracket 120 can remain relatively stable, so that the seat cushion body 110 can remain stable.

[0192] In some examples, the seat cushion bracket 120 can include a first side wall 121 and a second side wall 122 that are oppositely arranged along the width direction Y of the vehicle 10. Part of the shock-absorbing mechanism 130 can be located between the first side wall 121 and the second side wall 122.

[0193] In some examples, an adapter 140 for connecting to the shock-absorbing mechanism 130 can be provided between the first side wall 121 and the second side wall 122. The adapter 140 can be sleeved outside the outer cylinder body 133, and the adapter 140 and the outer cylinder body 133 can be in interference fit.

[0194] Exemplarily, along the width direction Y of the vehicle 10, one end of the adapter 140 is connected to the first side wall 121, and the other end of the adapter 140 is connected to the second side wall 122. The adapter 140 and the shock-absorbing mechanism 130 can be concentrically arranged. Both ends of the inner shaft body 1312 of the shock-absorbing mechanism 130 can extend out of both ends of the adapter 140 for connecting to the support member 150.

[0195] In some realizable ways, referring to Figure 7 as shown, the support member 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 oppositely arranged along the width direction Y of the vehicle 10. The first bracket 153 and the second bracket 154 are respectively connected to both 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 to both ends of the inner shaft body 1312. The first bracket 153 and the second bracket 154 can provide stable support for both ends of the inner shaft body 1312 to improve the connection stability between the shock-absorbing mechanism 130 and the vehicle frame 200. Thus, when encountering a bumpy road condition, the shock-absorbing mechanism 130 can buffer the bump impact force to improve the riding comfort and safety.

[0197] Among them, the first bracket 153 and the second bracket 154 may not be connected. One end of the first bracket 153 is connected to one end of the inner shaft body 1312, and the other end of the first bracket 153 is connected to the vehicle frame 200. One end of the second bracket 154 is connected to the other end of the inner shaft body 1312, and the other end of the second bracket 154 is connected to the vehicle frame 200.

[0198] In some examples, the first bracket 153 and the second bracket 154 may be respectively provided with special-shaped holes 100b. The inner shaft body 1312 may be provided with a special-shaped portion 1341 for cooperating with the special-shaped holes 100b. Through the cooperation of the special-shaped portion 1341 and the special-shaped holes 100b, relative rotation between the inner shaft body 1312 and the support member 150 is not likely to occur.

[0199] In some examples, the connection between the first bracket 153 and the vehicle frame 200 may be a detachable connection. The connection between the second bracket 154 and the vehicle frame 200 may be a detachable connection.

[0200] In some implementable ways, referring to Figure 8 and Figure 11 As shown, a limiting member 160 is provided on one of the seat cushion bracket 120 and the vehicle frame 200 of the embodiment of the present application. When the limiting member 160 is connected to the other of the seat cushion bracket 120 and the vehicle frame 200, there is a spacing between the seat cushion body 110 and the rear mudguard 500 of the vehicle 10 and / or the vehicle frame 200.

[0201] In the embodiment of the present application, when encountering a bumpy road condition, the vehicle frame 200 floats up and down, so that the seat cushion body 110 approaches or moves away from the vehicle frame 200. By providing the limiting member 160, it can be used to restrict the maximum angle of relative rotation between the internal member 131 and the external member, so as to restrict the minimum distance between the vehicle frame 200 and the seat cushion body 110, so that collisions are not likely to occur between the seat cushion body 110 and the rear mudguard 500 of the vehicle 10 and between the seat cushion body 110 and the vehicle frame 200.

[0202] It is easy to understand that when the seat cushion body 110 collides with at least one of the rear mudguard 500 or the vehicle frame 200, the rear mudguard 500 or the vehicle frame 200 will exert a reaction force on the seat cushion body 110, causing the rider to have a sense of vibration and affecting the riding experience. Moreover, when the seat cushion body 110 collides with the rear mudguard 500 or the vehicle frame 200, it is easy to cause deformation of the rear mudguard 500 or the vehicle frame 200.

[0203] Among them, the limiting member 160 can be arranged on the seat cushion bracket 120. In the normal riding state, along the height direction Z of the vehicle 10, there can be a spacing between the limiting member 160 and the vehicle frame 200. When encountering a bumpy road condition, when the limiting member 160 contacts the vehicle frame 200, there is a spacing between the seat cushion body 110 and the rear fender 500, and there is also a spacing between the seat cushion body 110 and the vehicle frame 200.

[0204] Alternatively, the limiting member 160 can also be arranged on the vehicle frame 200. In the normal riding state, along the height direction Z of the vehicle 10, there can be a spacing between the limiting member 160 and the seat cushion bracket 120. When encountering a bumpy road condition, when the limiting member 160 contacts the seat cushion bracket 120, there is a spacing between the seat cushion body 110 and the rear fender 500, and there is also a spacing between the seat cushion body 110 and the vehicle frame 200.

[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. Both ends of the limiting member 160 can be respectively connected to the first side wall 121 and the second side wall 122.

[0206] In some realizable ways, referring to Figure 6 、 Figure 8 and Figure 11 As shown, at least one of the seat cushion bracket 120 and the vehicle frame 200 of the embodiment of the present application is provided with a buffer member 170.

[0207] When the limiting member 160 is arranged on the seat cushion bracket 120, along the height direction Z of the vehicle 10, at least part of the buffer member 170 is located between the limiting member 160 and the vehicle frame 200. Alternatively, when the limiting member 160 is arranged on the vehicle frame 200, along the height direction Z of the vehicle 10, at least part of the buffer member 170 is located between the limiting member 160 and the seat cushion bracket 120.

[0208] 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 vehicle frame 200 or between the limiting member 160 and the seat cushion bracket 120, so that it is not easy for a rigid collision to occur between the limiting member 160 and the vehicle frame 200 or between the limiting member 160 and the seat cushion bracket 120, thereby reducing the vibration feeling caused by the rigid collision to the rider and the possibility of affecting the riding safety and comfort.

[0209] In some realizable ways, referring to Figure 3 As shown, one of the seat cushion bracket 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 to the other of the seat cushion bracket 120 and the support member 150, there is a spacing between the seat cushion body 110 and the rear fender 500 and / or the vehicle frame 200 of the vehicle 10.

[0210] In the embodiments of the present application, the support member 150 may be disposed on the vehicle frame 200.

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

[0213] In the embodiments of the present application, on bumpy roads, the buffer member 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 cushion bracket 120, so that it is not easy to have a rigid collision between the limiting member 160 and the vehicle frame 200 or between the limiting member 160 and the seat cushion bracket 120, thereby reducing the vibration feeling caused by the rigid collision to the rider and the possibility of affecting the riding safety and comfort.

[0214] In some examples, as shown in Figure 8 When the limiting member 160 is disposed on the seat cushion bracket 120, the buffer member 170 can be disposed on the support member 150 on the vehicle frame 200.

As shown in Figure 11As shown, when the limiting member 160 is disposed on the side of the seat cushion bracket 120 facing the vehicle frame 200, the buffer member 170 can be disposed on the structure of the limiting member 160 itself.

[0218] In some examples, the material of the buffer member 170 can be, but not limited to, rubber, foam, etc. The buffer member 170 can absorb the acting force between the limiting member 160 and the vehicle frame 200.
