[0040] The seat adjustment mechanism 100 according to an embodiment of the first aspect of the present invention will be described below with reference to the accompanying drawings.

[0041] like Figure 1-Figure 12 As shown, the seat adjustment mechanism 100 according to the embodiment of the first aspect of the utility model comprises: a base 1, a seat frame 2 and an angle adjustment assembly 3, the rear end of the seat frame 2 is rotatably arranged on the base 1, the angle adjustment assembly 3 comprises a first driving unit 32 and at least two groups of connecting rod groups 31, such as the connecting rod groups 31 can be provided with two groups, three groups, four groups, etc., and no specific restrictions are made here. Among them, each group of connecting rod groups 31 comprises a first connecting rod 311, a second connecting rod 312 and a third connecting rod 313, the first ends of the first connecting rod 311 and the second connecting rod 312 are rotatably connected to the base 1, the second ends of the first connecting rod 311 and the second connecting rod 312 are rotatably connected to the two ends of the third connecting rod 313 respectively, and any end of the third connecting rod 31 is rotatably connected to the front end of the seat frame 2 at the same time, and the first driving unit 32 is used to drive one of the first connecting rod 311 and the second connecting rod 312 to rotate relative to the base 1.

[0042] That is to say, the front end of the seat frame 2 is rotatably connected to the base 1 through the connecting rod group 31, and at least two groups of connecting rod groups 31 can improve the transmission stability of the angle adjustment component 3, wherein the connecting rod group 31, namely the first connecting rod 311, the second connecting rod 312 and the third connecting rod 313, can form a four-link structure together with the base 1, and the first driving unit 32 drives the first connecting rod 311 or the second connecting rod 312 to rotate relative to the base 1, which can better drive the connecting rod group 31 to deform, thereby driving the front end of the seat frame 2 to rotate around the rotation connection point between the rear end of the seat frame 2 and the base 1 to adjust the elevation angle of the seat frame 2 relative to the base 1, wherein the seat frame 2 is the internal skeleton of the seat cushion, therefore, by adjusting the elevation angle of the seat frame 2 relative to the base 1, the elevation angle of the seat cushion can be better adjusted, such as realizing the zero gravity mode of the seat, which is beneficial to improving the riding comfort of the driver and passengers. Among them, the four-link structure has a long transmission stroke and high transmission stability, thereby, the adjustment range and stability of the angle of the seat frame 2 of the angle adjustment component 3 can be better improved, so that the seat cushion can have a larger angle adjustment range to meet the riding needs of different drivers and passengers, and at the same time, the stability of the seat cushion angle adjustment is high.

[0043] According to the seat adjustment mechanism 100 of the first aspect of the utility model embodiment, the first link 311, the second link 312 and the third link 313 can form a four-link structure together with the base 1, which can better improve the adjustment range and stability of the angle of the seat frame 2 of the angle adjustment component 3, so that the seat cushion can have a larger angle adjustment range to meet the riding needs of different drivers and passengers, and at the same time, the stability of the seat cushion angle adjustment is high.

[0044] According to some embodiments of the utility model, the first connecting rod 311 and the second connecting rod 312 are arranged at intervals along the left-right direction. Therefore, during the rotation of the first connecting rod 311 and the second connecting rod 312 relative to the base 1, the first connecting rod 311 and the second connecting rod 312 are arranged at intervals along the left-right direction, which can better avoid the first connecting rod 311 and the second connecting rod 312 from interfering with each other during the rotation process, which is conducive to improving the transmission stability of the connecting rod assembly 31.

[0045] In a specific example, the first link 311 is located on the inner side of the second link 312, and in the left-right direction, the third link 313 is located between the first link 311 and the second link 312. The outer side surface of the second end of the first link 311 is opposite to the inner side surface of one end of the third link 313, and the inner side surface of the second end of the second link 312 is opposite to the outer side surface of the other end of the third link 313. By separating the first link 311 and the second link 312 by the third link 313, the risk of interference between the first link 311 and the second link 312 during rotation can be further reduced.

[0046] According to some embodiments of the utility model, the connecting rod group 31 has an unfolded state and a folded state. When the connecting rod group 31 switches from the folded state to the unfolded state, the front end of the seat frame 2 is lifted.

In other words, the rotation connection point of the second connecting rod 312 and the third connecting rod 313 is located above the plane where the axis of rotation of the first connecting rod 311 relative to the base 1, the axis of rotation of the second connecting rod 312 relative to the base 1, and the axis of rotation of the third connecting rod 313 relative to the first connecting rod 311 are located. The second connecting rod 312 and the third connecting rod 313 both have an angle with the plane where the axis of rotation of the first connecting rod 311 relative to the base 1, the axis of rotation of the second connecting rod 312 relative to the base 1, and the axis of rotation of the third connecting rod 313 relative to the first connecting rod 311 are located, so The connecting rod group 31 in the folded state can roughly form a triangular structure with the base 1, that is, the second connecting rod 312 can constitute the first side of the triangular structure, the third connecting rod 313 can constitute the second side of the triangular structure, and the line segment with the connection position between the second connecting rod 312 and the base 1 and the connection position between the first connecting rod 311 and the third connecting rod 313 as endpoints constitutes the third side of the triangular structure. The triangular structure has higher stability, so that the stability of supporting the seat frame 2 when the connecting rod group 31 is in the folded state can be better improved, which is beneficial to improving the riding comfort of the seat.

[0047] In a specific example, when the connecting rod group 31 is in a folded state, the first connecting rod 311 abuts against the chassis, so that the downward rotation angle of the first connecting rod 311 can be better limited through the chassis, while having a good supporting effect on the first connecting rod 311, and is beneficial to improving the supporting strength of the connecting rod group 31 in the folded state on the seat frame 2.

[0048] According to some embodiments of the utility model, the first driving unit 32 is used to drive the first connecting rod 311 to rotate relative to the base 1, the front end of the third connecting rod 313 is rotationally connected to the second end of the first connecting rod 311, and the rear end of the third connecting rod 313 is rotationally connected to the second end of the second connecting rod 312 and the front end of the seat frame 2. Therefore, by driving the first connecting rod 311 to rotate relative to the base through the first driving unit 32, the third connecting rod 313 can be rotationally connected with the first connecting rod 311 and the front end of the seat frame 2 to adjust the pitch angle of the front end of the seat frame 2.

Therefore, by driving the first connecting rod 311 to rotate relative to the base through the first driving unit 32, the third connecting rod 313 can be rotationally connected to the first connecting rod 311 and the front end of the seat frame 2 to adjust the pitch angle of the front end of the seat frame 2.

[0052] In a specific example, if Fig.11As shown, the first driving unit 32 is used to drive the second connecting rod 312 to rotate relative to the base 1, the connection position of the first connecting rod 311 and the base 1 is located in front of the connection position of the second connecting rod 312 and the base 1, the upper end of the first connecting rod 311 is rotationally connected to the front end of the third connecting rod 313, the upper end of the second connecting rod 312 is rotationally connected to the rear end of the third connecting rod 313, the front end of the seat frame 2 is rotationally connected to the front end of the third connecting rod 313, the first connecting rod 311 and the second connecting rod 312 are both tilted forward, and when the connecting rod group 31 switches from the unfolded state to the folded state, the first driving unit 32 drives the second connecting rod 312 and simultaneously drives the first connecting rod 311 to rotate in the counterclockwise direction relative to the base 1, and when the connecting rod group 31 switches from the folded state to the unfolded state, the first driving unit 32 drives the second connecting rod 312 and simultaneously drives the first connecting rod 311 to rotate in the clockwise direction relative to the base 1.

[0053] In another specific example, Fig.12 As shown, the first driving unit 32 is used to drive the second connecting rod 312 to rotate relative to the base 1, the connection position of the first connecting rod 311 and the base 1 is located in front of the connection position of the second connecting rod 312 and the base 1, the upper end of the first connecting rod 311 is rotationally connected to the front end of the third connecting rod 313, the upper end of the second connecting rod 312 is rotationally connected to the rear end of the third connecting rod 313, the front end of the seat frame 2 is rotationally connected to the front end of the third connecting rod 313, the first connecting rod 311 and the second connecting rod 312 are both tilted backward, and when the connecting rod group 31 switches from the unfolded state to the folded state, the first driving unit 32 drives the second connecting rod 312 and simultaneously drives the first connecting rod 311 to rotate in a clockwise direction relative to the base 1, and when the connecting rod group 31 switches from the folded state to the unfolded state, the first driving unit 32 drives the second connecting rod 312 and simultaneously drives the first connecting rod 311 to rotate in a counterclockwise direction relative to the base 1.

[0054] According to some embodiments of the utility model, the angle adjustment assembly 3 further includes a first synchronous coupling 33, each first connecting rod 311 is rotatably connected to the base 1 through a recliner 34, and multiple recliners 34 are all transmission-connected to the first synchronous coupling 33, and the first driving unit 32 is used to drive the first synchronous coupling 33 to rotate. That is, by driving the first synchronous coupling 33 to rotate through the first driving unit 32, the parts connected to the multiple recliners 34 connected thereto and the first connecting rod 311 can be driven to rotate, thereby simultaneously driving the first connecting rods 311 of multiple connecting rod groups 31 to rotate relative to the base 1, and then driving the multiple connecting rod groups 31 to move through the multiple first connecting rods 311 to drive the seat frame 2 to rotate relative to the base 1, and adjust the pitch angle of the seat frame 2. In this way, the synchronous transmission of multiple connecting rod groups 31 can be achieved, so that the left and right sides of the front end of the seat frame 2 can be lifted or lowered at the same speed and stroke during the angle adjustment process, which is conducive to improving the stability of the angle adjustment of the seat frame 2.

[0056] It should be noted that the transmission method between the first drive unit 32 and the two groups of connecting rods 31 is not limited to this. The driving method of multiple first connecting rods 311 through the first synchronous connecting shaft 33 is within the protection scope of this application and is not specifically limited here.

[0057] According to some embodiments of the utility model, the seat frame 2 includes a seat frame body and a height adjustment component 4, the height adjustment component 4 includes a first height adjustment link 41, a second height adjustment link 42 and a second drive unit 43, the first height adjustment link 41 and the second height adjustment link 42 are arranged at intervals in the front-to-back direction, the first height adjustment link 41 and the second height adjustment link 42 are both multiple and arranged at intervals along the left-to-right direction, the upper end of the first height adjustment link 41 is rotatably connected to the seat frame body, the lower end of the first height adjustment link 41 is rotatably connected to the third link 313, the upper end of the second height adjustment link 42 is rotatably connected to the seat frame body, the lower end of the second height adjustment link 42 is rotatably connected to the base 1, and the second drive unit 43 is used to drive the second height adjustment link 42 to rotate relative to the base 1.

[0058] That is to say, a quadrilateral structure can be formed between the first height-adjusting link 41, the corresponding second height-adjusting link 42, the seat frame body and the base 1. Therefore, by driving the second height-adjusting link 42 to rotate relative to the base 1 through the second driving unit 43, the angle between the second height-adjusting link 42 and the base 1 in the horizontal direction can be well adjusted. As the angle between the second height-adjusting link 42 and the base 1 in the horizontal direction changes, the interval between the seat frame body and the base 1 in the vertical direction also changes accordingly, so that the height of the seat frame body relative to the base 1 can be adjusted, thereby achieving the adjustment of the seat height. Therefore, the seat adjustment mechanism 100 can adjust the elevation angle of the seat cushion and the height of the seat at the same time, which can well improve the flexibility of seat adjustment to meet the riding needs of different drivers and passengers.

[0059] In a specific example, two first height adjustment links 41 and two second height adjustment links 42 are provided, and two links 31 are provided, and a first height adjustment link 41, a second height adjustment link 42 and a link 31 are provided on the left and right sides of the seat frame body, respectively.

In other words, the transmission gear can be driven to rotate synchronously by the rotation of the output shaft of the driving motor, so that the second height-adjusting connecting rod 42 is driven to rotate relative to the base 1 through the cooperation of the transmission gear and the matching tooth plate 44 to adjust the height of the seat frame 2. Therefore, the transmission is realized through the cooperation of the transmission gear and the matching tooth plate 44, the structural unit has high stability, and the efficiency of power transmission from the driving motor to the second height-adjusting connecting rod 42 can be improved.

[0062] According to some embodiments of the utility model, the height adjustment assembly 4 further includes a second synchronous coupling 45, which is rotatably disposed on the seat frame body and fixedly connected to the upper ends of the plurality of second height adjustment links 42. That is, when the second height adjustment links 42 are driven to rotate relative to the base by the second driving unit 43, the second synchronous coupling 45 is driven to rotate relative to the seat frame body, and the inclination angle of the second height adjustment links 42 relative to the base 1 and the seat frame body is adjusted, so that the height of the seat frame body is adjusted by adjusting the inclination angle of the second height adjustment links 42.

[0063] In a specific example, the mating tooth plate 44 is arranged on the second height adjustment link 42 located on the left side, and the two ends of the second synchronous connecting shaft 45 are respectively connected to the left and right sides of the seat frame 2 for rotation.
