[0026] The embodiments of the present utility model are described in detail below. The embodiments described with reference to the accompanying drawings are exemplary. The embodiments of the present utility model are described in detail below.

[0027] Reference below Figure 1-Figure 3 A seat 1 according to an embodiment of the present invention is described.

[0028] like Figure 1 As shown, the seat 1 according to the embodiment of the utility model includes: a backrest 10, a seat cushion 20 and a height adjustment mechanism 30. The backrest 10 can mainly support the waist and back of the passenger, so as to improve the comfort of the passenger's waist and back. Similarly, the seat cushion 20 can mainly support the buttocks of the passenger, so as to improve the overall comfort of the passenger and to a certain extent improve the safety of the passenger during driving. The height adjustment mechanism 30 can adjust the height of the seat cushion 20 close to one end of the backrest 10 without adjusting the angle of the backrest 10.

[0029] like Figure 1As shown, the height adjustment mechanism 30 is arranged at one end of the seat cushion 20 close to the backrest 10. Without adjusting the angle of the backrest 10, the height adjustment mechanism 30 can adjust the height of the seat cushion 20 close to the backrest 10. In other words, the backrest 10 can be rotated relative to the seat cushion 20 first. When the backrest 10 is rotated to a suitable position, the height adjustment mechanism 30 adjusts the lifting height of the seat cushion 20. In this way, the lifting of the seat cushion 20 and the backward folding of the backrest 10 are independent of each other and do not affect each other. The lifting of the seat cushion 20 is not restricted by whether the backrest 10 is adjusted backward.

[0030] Moreover, when the backrest 10 is not laid down, after the backrest 10 is rotated, the height adjustment mechanism 30 can lift the end of the seat cushion 20 adjacent to the backrest 10. It can be understood that when the backrest 10 is rotated, the end of the backrest 10 adjacent to the seat cushion 20 will be relatively raised. At this time, the height adjustment mechanism 30 lifts the end of the seat cushion 20 adjacent to the backrest 10, which can reduce the height difference between the backrest 10 and the seat cushion 20, that is, improve the smoothness of the connection between the backrest 10 and the seat cushion 20, and even achieve that the seat cushion 20 is almost flush with the backrest 10, thereby meeting the riding needs of different scenarios.

[0031] Therefore, the lifting mechanism of the seat cushion 20 and the backrest 10 are adjusted backward to form two independent and mutually non-interfering seat rear lifting mechanisms. A height adjustment structure 30 is provided at one end of the seat cushion close to the backrest, which can achieve the adjustment of the height of the end of the seat cushion 20 close to the backrest 10 without adjusting the angle of the backrest 10, thereby reducing the height difference between the backrest 10 and the seat cushion 20, and achieving that the seat cushion 20 is almost flush with the backrest 10. This will not affect the comfort of the seat 1 and avoid discomfort to consumers during use. At the same time, it will also enable consumers to experience the comfort brought by different states of the seat 1 during actual riding and meet the riding needs of different scenarios.

[0032] Specifically, Figure 1 , Figure 2 and Figure 3As shown, the seat cushion 20 includes: a seat cushion frame 23, and the height adjustment mechanism 30 includes: a first driving member 21 and a transmission assembly 22, one end of the transmission assembly 22 is connected to the first driving member 21, and the other end is connected to the seat cushion frame 23, and the first driving member 21 drives the transmission assembly 22 to drive the end of the seat cushion frame 23 close to the backrest 10 to rise to a preset height. It should be noted that the first driving member 21 can mainly play a driving role, the transmission assembly 22 can mainly play an intermediate transmission role, and the seat cushion frame 23 is the main part of the seat cushion, which can play a supporting and fixing role. One end of the transmission component 22 is connected to the first driving member 21, and the other end is connected to the cushion frame 23. The first driving member 21 can drive the transmission component 22 to drive the movement of the transmission component 22. The transmission component 22 is connected to the cushion frame 23. At this time, the transmission component 22 can drive the cushion frame 23 to move. That is to say, the first driving member 21 drives the transmission component 22, which can lift one end of the cushion frame 23 adjacent to the backrest 10, driving the cushion frame 23 to rise to a preset height, thereby reducing the height difference between the backrest 10 and the seat cushion 20.

[0033] Among them, Figure 1 , Figure 2 and Figure 3 As shown, the transmission assembly 22 includes: a screw rod 220, a sleeve 221, a first linkage assembly 222 and a second linkage assembly 223. The first driving member 21 is driven and cooperated with the screw rod 220. The screw rod 220 is movably arranged on the sleeve 221. The first linkage assembly 222 is connected to the sleeve 221. The second linkage assembly 223 is connected to the first linkage assembly 222, and the second linkage assembly 223 is connected to the cushion frame 23.

[0034] Specifically, the first driving member 21 realizes driving cooperation with the transmission assembly 22 by driving cooperation with the screw rod 220. The screw rod 220 is movably arranged in the sleeve 221. At this time, the screw rod 220 can move back and forth in the sleeve 221. It can be understood that the back and forth movement of the screw rod 220 in the sleeve 221 can drive the sleeve 221 to rotate. The first linkage assembly 222 is connected to the sleeve 221, so that the sleeve 221 can drive the first linkage assembly 222 to rotate. The second linkage assembly 223 is connected to the first linkage assembly 222. The first linkage assembly 222 can drive the second linkage assembly 223 to rotate. The second linkage assembly 223 is connected to the seat cushion frame 23. At this time, the seat cushion frame 23 can rotate with the second linkage assembly 223, thereby making the seat cushion frame 23 The end adjacent to the backrest 10 can be lifted, thereby reducing the height difference between the backrest 10 and the seat cushion 20.

[0035] In addition, if Figure 1 and Figure 2As shown, the first linkage component 222 includes: a first connecting member 224, a second connecting member 225 and a linkage shaft 226, the first connecting member 224 is connected to the sleeve 221, and the first connecting member 224 is connected to the second connecting member 225, the second connecting member 225 is connected to the linkage shaft 226, and the linkage shaft 226 is connected to the second linkage component 223, so that the first connecting member 224, the second connecting member 225 and the linkage shaft 226 rotate around the linkage shaft 226.

[0036] Specifically, the first connecting member 224 is connected to the sleeve 221 to realize the connection between the first linkage assembly 222 and the sleeve 221, and the first connecting member 224 is connected to the second connecting member 225. At this time, the first connecting member 224 and the second connecting member 225 form a whole, and the second connecting member 225 is connected to the linkage shaft 226. At this time, the first connecting member 224, the second connecting member 225 and the linkage shaft 226 form a whole, which is convenient for the installation and setting of the first linkage assembly 222. The linkage shaft 226 is connected to the second linkage assembly 223, so as to drive the rotation of the second linkage assembly 223. In addition, the first connecting member 224, the second connecting member 225 and the linkage shaft 226 rotate with the linkage shaft 226 as the axis, which is convenient for arrangement, and when the first linkage assembly 222 rotates, the overall rotation space of the first linkage assembly 222 can be reduced.

[0037] Among them, the first connecting member 224 and the second connecting member 225, as well as the second connecting member 225 and the linkage shaft 226 can be connected by welding. The first connecting member 224 and the second connecting member 225, as well as the second connecting member 225 and the linkage shaft 226 can be welded by a special welding machine. This can make the weld smooth, the size accurate, the structure simple and elegant, and can ensure the firmness and reliability of the connection between the first connecting member 224 and the second connecting member 225, as well as the second connecting member 225 and the linkage shaft 226.

[0038] Of course, if Figure 1 and Figure 2As shown, the second linkage assembly 223 includes: a third connection member 227 and a clamping member 228, the third connection member 227 is connected to the linkage shaft 226, and the third connection member 227 is connected to the clamping member 228, and the clamping member 228 is clamped and matched with the cushion frame 23. Specifically, the third connection member 227 can mainly play a connecting role, and the clamping member 228 can mainly play a role of clamping and fixing connection. The third connecting member 227 is connected to the linkage shaft 226, so that when the linkage shaft 226 rotates, the third connecting member 227 can rotate with the linkage shaft 226. The third connecting member 227 is connected to the clamping member 228, so that the third connecting member 227 can drive the clamping member 228 to rotate, and the clamping member 228 is clamped with the seat cushion frame 23. The clamping connection method is simpler and more convenient, and the connection between the clamping member 228 and the seat cushion frame 23 can be firm and reliable. In addition, the clamping member 228 can drive the seat cushion frame 23 to rotate, so that the seat cushion frame 23 is lifted upward, and the height difference between the backrest 10 and the seat cushion 20 is reduced. Among them, the third connecting member 227 and the linkage shaft 226 can be welded, so that the weld can be flat, the size is accurate, the structure is simple and generous, and the firmness and reliability of the connection between the third connecting member 227 and the linkage shaft 226 can be guaranteed.

[0039] Furthermore, if Figure 1 and Figure 2 As shown, the second linkage assembly 223 also includes: a locking member 229, which is connected to the third connecting member 227, and the locking member 229 is locked with the seat cushion frame 23. The locking member 229 can mainly play the role of emergency protection and precise positioning. The locking member 229 is connected to the third connecting member 227, so that the locking member 229 and the third connecting member 227 can form a whole, which is convenient for the installation and arrangement of the second linkage assembly 223. In addition, the locking member 229 is locked with the seat cushion frame 23, so that the seat cushion 20 can be kept in a relative state after the seat cushion 20 is lifted, meeting the established working effect.

[0040] In addition, Figure 1 and Figure 2 As shown, the locking member 229 is welded to the third connecting member 227, or the locking member 229 is integrally formed on the third connecting member 227. That is to say, the locking member 229 and the third connecting member 227 can be welded by a special welding machine, which can make the weld smooth, the size accurate, the structure simple and generous, and can ensure the firmness and reliability of the connection between the locking member 229 and the third connecting member 227, or the locking member 229 is integrally formed on the third connecting member 227, in which case the locking member 229 and the third connecting member 227 are an integrated structure, which is more stable and firm, easy to install, and only requires one processing mold, which is easy to produce.

[0041] It should be noted that if Figure 1 and Figure 2 As shown, the seat cushion 20 further includes: a fixing member 201, and the first driving member 21 is mounted on the fixing member 201. In this way, the fixing member 201 can support the first driving member 21, which is convenient for the first driving member 21 to be subjected to force, and the fixing member 201 can be used to install and fix the first driving member 21, so that the first driving member 21 can be firmly fixed on the seat cushion 20, making the arrangement of the first driving member 21 more stable.

[0042] In addition, if Figure 1 As shown, the backrest 10 is provided with a rotating mechanism 104 for adjusting the angle of the backrest 10, and the rotating mechanism 104 and the height adjustment mechanism 30 of the seat cushion 20 are independently arranged. The rotating mechanism 104 is mainly used to adjust the angle of the backrest 10, and the rotating mechanism 104 and the height adjustment mechanism 30 of the seat cushion 20 are independently arranged, so that the lifting of the seat cushion 20 and the backward folding of the backrest 10 are independent of each other and do not affect each other, and the lifting of the seat cushion 20 is not restricted by whether the backrest 10 is adjusted backward.

[0043] Alternatively, if Figure 1 As shown, the backrest 10 includes: a backrest frame 103, and the rotating mechanism 104 includes: a second driving member 101 and a rotating shaft 102. The second driving member 101 is used to drive the backrest frame 103 to rotate with the rotating shaft 102 as the axis. The second driving member 101 mainly plays a driving role, and the rotating shaft 102 can withstand bending moment and torque during the rotation work. The backrest frame 103 is an important component of the backrest 10, which can mainly play the role of maintaining a correct sitting posture, providing support for the upper body when turning, and providing protection for the upper body when colliding. In this way, the second driving member 101 can drive the backrest frame 103 to rotate with the rotating shaft 102 as the axis, and at this time, the normal rotation of the backrest 10 can be guaranteed, thereby achieving the established working effect.
