[0034] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to be used to explain the present invention, but cannot be understood as limiting the present invention.

[0035] Combine the following Figure 1-Figure 8 A shock-absorbing vehicle seat according to an embodiment of the present invention is described.

[0036] The shock-absorbing vehicle seat of the embodiment of the utility model comprises a first four-bar mechanism, a second four-bar mechanism and an elastic component 7. The first four-bar mechanism comprises a transition seat tube 2, a first connecting rod 4, an intermediate connecting rod 3 and a second connecting rod 5 which are pivotally connected in sequence, and the second connecting rod 5 is also pivotally connected to the transition seat tube 2, and the transition seat tube 2 is used to be connected to the vehicle seat column of the vehicle body. The second four-bar mechanism comprises an intermediate connecting rod 3, a first connecting rod 4, a vehicle seat 1 and a third connecting rod 6 which are pivotally connected in sequence, and the third connecting rod 6 is also pivotally connected to the intermediate connecting rod 3, and the vehicle seat 1 has a first critical position and a second critical position, and the first critical position is higher than the second critical position. The elastic component 7 is suitable for pressing the vehicle seat 1 toward the first critical position.

[0037] According to the shock-absorbing vehicle seat of the embodiment of the utility model, the transition seat tube 2, the first connecting rod 4, the intermediate connecting rod 3 and the second connecting rod 5 form a first four-bar mechanism, and the intermediate connecting rod 3, the first connecting rod 4, the vehicle seat 1 and the third connecting rod 6 form a second four-bar mechanism. Through the first connecting rod 4 and the intermediate connecting rod 3 shared therein, the vehicle seat 1 is ensured to move relative to the transition seat tube 2 in a set trajectory, and then after the transition seat tube 2 is connected to the vehicle body column, the vehicle seat 1 can move between a first critical position and a second critical position of different heights. Among them, the elastic component 7 can support the vehicle seat 1 to maintain the vehicle seat 1 at the first critical position without being acted upon by external forces. When the vehicle seat 1 is pressed to move toward the second critical position, the elastic component 7 can undergo elastic deformation to slow down the movement speed of the vehicle seat 1, thereby achieving a shock-absorbing effect and providing the rider with better riding comfort.

[0038] In addition, the six-bar mechanism formed by the first four-bar mechanism and the second four-bar mechanism enables the seat 1 to have a more complex motion trajectory than the transition seat tube 2, compared to a simple four-bar mechanism, and can enable the seat 1 to have a smaller tilt angle change when moving in the height direction. The seat 1 has higher support stability for the rider and the rider has higher riding comfort.

[0039] It should be noted that Figure 5 As shown, the first link 4, the second link 5 and the third link 6 are pivotally connected to the middle link 3 around axes at three different positions, respectively. The two ends of the first link 4 are pivotally connected to the seat 1 and the transition seat tube 2, respectively. The adjacent middle position of the first link 4 is pivotally connected to the upper end of the middle link 3.

[0040] In some embodiments, the pivoting direction of the first link 4 relative to the intermediate link 3 is the same as the pivoting direction of the third link 6 relative to the intermediate link 3 .

[0041] like Figure 4 and Figure 5As shown, the pivot direction of the first link 4 relative to the middle link 3 and the pivot direction of the third link 6 relative to the middle link 3 are both counterclockwise. At this time, when the first link 4 rotates counterclockwise relative to the transition seat tube 2 to drive the seat 1 to move downward, under the pulling of the third link 6, the seat 1 will not rotate counterclockwise synchronously with the first link 4 relative to the transition seat tube 2, thereby making the rotation angle of the seat 1 smaller, providing higher support stability for the rider, and improving the riding comfort of the rider.

[0042] Specifically, Figure 4 and Figure 5 As shown, the inclination angle of the upper surface of the vehicle seat 1 at the first critical position relative to the horizontal plane is substantially the same as the inclination angle of the upper surface of the vehicle seat 1 at the second critical position relative to the horizontal plane.

[0043] In some embodiments, Figure 2 and Figure 3 As shown, the transition seat tube 2 includes an outer tube 21 and a base 22, and the base 22 is installed in the inner cavity of the outer tube 21. The elastic component 7 includes a connecting piece and a spring 71, the connecting piece is pivotally connected to the intermediate connecting rod 3, the spring 71 is located in the inner cavity of the outer tube 21, and the spring 71 is connected between the connecting piece and the base 22.

[0044] That is, the spring 71 supports the vehicle seat 1 by compressing the middle connecting rod 3. At the same time, the spring 71 is hidden in the inner cavity of the outer tube 21, which effectively prevents foreign matter from adhering to the spring 71 and interfering with the elastic deformation of the spring 71, so that the spring 71 has high support and shock absorption stability for the vehicle seat 1.

[0045] Specifically, there is a large gap between the outer circumference of the spring 71 and the inner circumference of the outer tube 21. The intermediate link 3 will be angularly offset as the seat 1 moves, which will drive the spring 71 to swing slightly. At this time, the design in which the connecting piece is pivotally connected to the lower end of the intermediate link 3 will further reduce the swing amplitude of the spring 71, thereby effectively preventing the spring 71 from swinging too much and causing failure of the spring 71.

[0046] In some embodiments, Figure 2 and Figure 3 As shown, the connecting member includes a first adapter 72 and a first guide rod 73 connected to each other. The first adapter 72 is pivotally connected to the intermediate connecting rod 3. The spring 71 is sleeved on the first guide rod 73 and clamped between the first adapter 72 and the base 22.

[0047] The first guide rod 73 guides the upper end of the spring 71, effectively preventing the upper end of the spring 71 from radially deviating, and also effectively preventing the spring 71 from swinging too much and causing the spring 71 to fail. The spring 71 has high support and shock-absorbing stability for the seat 1.

[0048] Specifically, the first guide rod 73 is a screw rod, and the upper end of the first guide rod 73 is threadedly engaged with the first adapter 72 .

[0049] In some embodiments, Figure 2 and Figure 3 As shown, the shock-absorbing seat also includes an adjusting nut 75. The first guide rod 73 is provided with an external thread. The adjusting nut 75 is threadedly connected to the first guide rod 73 through the external thread. The adjusting nut 75 is located on the side of the first adapter 72 facing the spring 71. The spring 71 is clamped between the adjusting nut 75 and the base 22.

[0050] By rotating the adjusting nut 75, the distance between the adjusting nut 75 and the base 22 can be adjusted, so as to adjust the minimum deformation of the spring 71 and effectively adjust the shock-absorbing strength of the shock-absorbing vehicle seat.

[0051] In some embodiments, the connecting member includes a second adapter 74 and a second guide rod 75, the second adapter 74 is pivotally connected to the intermediate link 3, the second guide rod 75 is slidably connected to the outer tube 21 along the axial direction of the outer tube 21, one end of the second guide rod 75 away from the second adapter 74 is located in the inner cavity of the outer tube 21 and connected to a first limit seat 76, and the spring 71 is sandwiched between the first limit seat 76 and the base 22. Figure 6 As shown, the second adapter 74 is fixedly connected to the end of the second guide rod 75 away from the first limit seat 76, or, as shown in Figure 7 As shown, the second adapter 74 is pivotally connected to the end of the second guide rod 75 away from the first limit seat 76, or, as shown in Figure 8 As shown, the second adapter 74 is a roller, which is pivotally connected to the intermediate connecting rod 3 around its central axis, and the outer peripheral surface of the roller is rollingly connected to an end surface of the second guide rod 75 away from the first limiting seat 76.

[0052] The sliding cooperation between the second guide rod 75 and the outer tube 21 allows the spring 71 in the outer tube 21 to only perform telescopic deformation along its axial direction, effectively preventing the spring 71 from swinging and causing the spring 71 to fail, and the spring 71 has high support and shock absorption stability for the vehicle seat 1. In addition, the second adapter 74 is pivotally connected to the middle link 3, and the second guide rod 75 is fixedly connected, pivotally connected, or rollingly connected, so that when the middle link 3 moves up and down, the second guide rod 75 does not interfere with the second adapter 74 and the outer tube 21, and can slide smoothly along the axial direction of the outer tube 21 and compress the spring 71.

[0053] Specifically, Figure 6-Figure 8As shown, the first limiting seat 76 is connected to the end face of the second guide rod 75 away from the second adapter 74 by a bolt, and the head of the bolt is inserted into the spring 71 to achieve radial limiting of the spring 71. A guide hole is formed on the mounting seat 23 of the transition seat tube 2, and the second guide tube can be slidably fitted in the guide hole. At this time, the mounting seat 23 separates the spring 71 from the outside, thereby further ensuring the support and shock absorption stability of the spring 71. In addition, as shown in FIG. Figure 7 and Figure 8 As shown, by arranging the second adapter 74 to be pivotally connected to the end of the second guide rod 75 away from the first limit seat 76, or by arranging the second adapter 74 to be a roller, the outer peripheral surface of the roller is rollingly connected to the end surface of the second guide rod 75 away from the first limit seat 76, both of which can effectively improve the movement freedom of the second adapter 74 to further reduce the probability of interference between the second adapter 74 and the second guide rod 75, thereby making the up and down movement adjustment stroke of the seat 1 larger and the shock absorbing effect better.

[0054] In some embodiments, the elastic component 7 further includes a second limit seat 77 and a third guide rod 78, the second limit seat 77 is connected to an end of the third guide rod 78 away from the connecting member, and the spring 71 is sleeved on the third guide rod 78 and sandwiched between the second limit seat 77 and the connecting member. Figure 2 and Figure 3 As shown, a limiting groove 771 is provided on the side of the second limiting seat 77 facing away from the third guide rod 78, and a protrusion 221 is provided on the side of the base 22 facing the second limiting seat 77. The protrusion 221 is engaged in the limiting groove 771, and the protrusion 221 can slide relative to the inner surface of the limiting groove 771 so that the third guide rod 78 can swing relative to the base 22.

[0055] The third guide rod 78 guides the lower end portion of the spring 71, effectively preventing the lower end of the spring 71 from radially deviating, and also effectively preventing the spring 71 from swinging too much and causing the spring 71 to fail. At the same time, only the protrusion 221 and the limiting groove 771 need to cooperate to limit the spring 71 in the radial direction, and also to realize the pivotability of the third guide rod 78 relative to the base 22, so that the spring 71 has high support and shock absorption stability for the seat 1.

[0056] Specifically, the limiting groove 771 is a hemispherical groove, and the outer surface of the protrusion 221 is a spherical surface matching the inner surface of the limiting groove 771 .

[0057] It should be noted that Figure 7 and Figure 8As shown, when the second adapter 74 is pivotally connected to the end of the second guide rod 75 away from the first limit seat 76, or is rollingly connected to the end face of the second guide rod 75 away from the first limit seat 76, the side of the base 22 facing the second limit seat 77 can also be provided with a first guide groove extending along the axial direction of the outer tube 21, and the second limit seat 77 is partially plugged into the first guide groove, and / or, the side of the second limit seat 77 facing the base 22 is provided with a second guide groove extending along the axial direction of the outer tube 21, and the base 22 is partially plugged into the second guide groove. At this time, the plugging of the second limit seat 77 and the base 22 realizes the relative fixation of the second limit seat 77 and the base 22 in the radial direction of the spring 71.

[0058] In some embodiments, a mounting hole is provided on the outer tube 21, a threaded hole is provided on the base 22, and the shock-absorbing saddle further comprises a first threaded member 9, which passes through the mounting hole and is threadably matched with the threaded hole.

[0059] like Figure 2 , Figure 3 and Figure 6 As shown, there are two mounting holes and they are coaxially arranged, threaded holes are respectively provided on opposite sides of the base 22, the first threaded member 9 is a bolt, there are two bolts and they correspond one to one with the mounting holes and the threaded holes, the bolts pass through the corresponding mounting holes and cooperate with the corresponding threads to realize the installation of the base 22 in the outer tube 21, and the installation of the base 22 is convenient and reliable.

[0060] In some embodiments, Figure 1-Figure 4 As shown, the transition seat tube 2 also includes a mounting seat 23, which is detachably connected to the upper end of the outer tube 21. The mounting seat 23 includes a mounting portion 231 located above the outer tube 21, and the mounting portion 231 and the intermediate connecting rod 3 are arranged in a direction perpendicular to the axial direction of the outer tube 21.

[0061] The mounting seat 23 is a non-standard part. By splitting the transition seat tube 2 into at least the mounting seat 23 and the outer tube 21 , it is convenient for both to be processed and for the elastic component 7 to be installed in the inner cavity of the outer tube 21 .

[0062] Specifically, the mounting seat 23 can be partially fitted in the outer tube 21 and connected via fasteners, or the outer tube 21 can be a round tube with an internal thread, and the mounting seat 23 is connected to the round tube thread via the internal thread.

[0063] In some embodiments, Figure 1 and Figure 2 As shown, the shock-absorbing seat further comprises a seat rod 8 , the upper end of which is detachably connected to the seat 1 , and the seat 1 is pivotally connected to the first connecting rod 4 and the third connecting rod 6 via the seat rod 8 .

[0064] The seat post 8 is formed to be pivotally connected to the first link 4 and the third link 6 , and the design of being detachably connected to the seat 1 makes the processing of the seat post 8 and the seat 1 simple and convenient with low processing cost.

[0065] Specifically, the upper end of the seat post 8 can be fixedly connected to the lower metal piece of the seat 1 through a clamp.

[0066] It should be noted that Figure 1 As shown, in order to improve the structural strength of the shock-absorbing seat, two seat rods 8 and two intermediate connecting rods 3 can be provided.

[0067] In some embodiments, Figure 4 and Figure 5 As shown, the transition seat tube 2 has a first limiting surface and a second limiting surface. When the seat 1 is at the first critical position, the intermediate connecting rod 3 abuts against the first limiting surface. When the seat 1 is at the second critical position, the intermediate connecting rod 3 abuts against the second limiting surface. The mounting seat 23 of the intermediate connecting rod 3 and the transition seat rod 8 is stronger than the first connecting rod 4 to the third connecting rod 6. The travel of the seat 1 is limited by the abutment of the two, ensuring that the components of the shock-absorbing seat will not be deformed due to excessive impact when the seat 1 reaches the first critical position and the second critical position, and the service life of the shock-absorbing seat is long.
