The lifting of the seat can be realized by independently driving the left rear linkage plate 122 or/and the right rear linkage plate 124, and the angle adjustment of the seat can be realized by independently driving the front linkage pipe 151.
The lifting working condition of the seat is as follows:
the driving member does not drive the front linkage pipe 151, at this time, the front linkage pipe 151, the left middle linkage plate 131, the left cushion side plate 141, the rear linkage pipe 152, the right cushion side plate 142 and the right middle linkage plate 132 form a fixed closed loop, the left front linkage plate 121, the left rear linkage plate 122, the right front linkage plate 123 and the right rear linkage plate 124 are respectively supported at the lower side of the fixed closed loop, the left front linkage plate 121, the left fixing plate 111, the left rear linkage plate 122 and the fixed closed loop form a four-link mechanism, the right front linkage plate 123, the right fixing plate 112, the right rear linkage plate 124 and the fixed closed loop form a four-link mechanism, and at this time, the left rear linkage plate 122 or/and the right rear linkage plate 124 are driven to realize the actions of the two four-link mechanisms, so that the fixed closed loop (especially, the left cushion side plate 141 and the right cushion side plate 142) moves up and down.
Seat angle adjustment operating mode:
the left rear linkage plate 122 or/and the right rear linkage plate 124 are/is not driven, and the left front linkage plate 121, the left rear linkage plate 122, the right front linkage plate 123 and the right rear linkage plate 124 are/is not moved. At this time, the front linkage pipe 151 is driven to rotate, and because the third end 103 of the left middle linkage piece 131 and the sixth end 106 of the right middle linkage piece 132 are respectively connected with the left end and the right end of the front linkage pipe 151, the front linkage pipe 151 rotates by taking a connecting line between the first end 101 of the left middle linkage piece 131 and the fourth end 104 of the right middle linkage piece 132 as an axis, so as to drive the second end 102 of the left middle linkage piece 131 and the fifth end 105 of the right middle linkage piece 132 to move, and therefore the left cushion side plate 141 and the right cushion side plate 142 both rotate along the axis of the rear linkage pipe 152, and angle adjustment of the seat is realized.
According to the electric seat adjusting mechanism 100 provided by the embodiment of the invention, the seat angle adjusting mechanism and the seat lifting adjusting mechanism are integrated, and compared with the traditional seat adjusting mechanism, a whole set of four-bar mechanism is omitted, so that the whole structure is simple, the occupied space is small, the number of parts is reduced, the weight of the seat is reduced, the light-weight design is improved, and the market competitiveness is improved.
In some embodiments of the present invention, the power seat adjustment mechanism 100 further comprises a recliner motor 161, the recliner motor 161 being configured to drive the front linkage tube 151 to rotate about the third end 103 of the left middle linkage piece 131 and the sixth end 106 of the right middle linkage piece 132.
Further, the electric seat adjusting mechanism 100 further includes a lifting motor 171, and the lifting motor 171 is used for driving the left rear linkage plate 122 or/and the right rear linkage plate 124 to rotate around the lower end thereof.
Specifically, the recliner motor 161 and the front linkage tube 151 are connected through a motor front fixing bracket 162, the front end of the motor front fixing bracket 162 is fixedly arranged on the front linkage tube 151, and the rear end of the motor front fixing bracket 162 is rotatably connected with the recliner motor 161. Thus, the motor can rotate around the rear end of the motor front fixing bracket 162 with the front linkage pipe 151 moving forward and backward.
For example, when the recliner motor 161 moves forward, the front link pipe 151 rotates forward and upward centering on the rear end of the motor front fixing bracket 162.
Further, the electric seat adjusting mechanism 100 further includes a motor rear fixing bracket 163, a front end of the motor rear fixing bracket 163 is connected to the shaft of the angle adjusting motor 161 through a screw structure, and a rear end of the motor rear fixing bracket 163 is rotatably connected to the rear linkage pipe 152.
When the motor shaft of the recliner motor 161 rotates, the lead screw can convert the rotation of the motor shaft into linear movement, and then the recliner motor 161 can move in the front-rear direction, and the motor can push the front linkage pipe 151 to rotate; and since the rear end of the motor rear fixing bracket 163 is rotatably provided on the rear linkage pipe 152, the upward movement of the front linkage pipe 151 is not affected.
Preferably, the rear fixing bracket is connected to the rear linkage pipe 152 by a rear fixing bracket connection plate 164, one end of the rear fixing bracket connection plate 164 is fixedly connected to the rear linkage pipe 152, and the other end of the rear fixing bracket connection plate 164 is rotatably connected to the rear linkage pipe 152. Thus, the motor rear fixing bracket 163 can have a certain movement margin in the front-rear direction, and the amount of movement of the recliner motor 161 in the front-rear direction is increased. Further, the seat angle adjustment range of the recliner motor 161 can be significantly increased.
In some embodiments of the present invention, racks are disposed on the left rear linkage plate 122 or/and the right rear linkage plate 124, a gear is disposed on the lifting motor 171, and the gear on the lifting motor 171 is engaged with the racks on the left rear linkage plate 122 or/and the right rear linkage plate 124.
Preferably, the left fixing plate 111 and the right fixing plate 112 are slidable in the front-rear direction, so that the electric seat adjusting mechanism 100 has a front-rear adjusting function, and the riding experience of passengers is further improved.
The operation of the power seat adjustment mechanism 100 of the present invention will be described in detail.
The angle adjusting motor 161 does not work, at this time, the angle adjusting motor 161, the motor front fixing bracket 162, the motor rear fixing bracket 163, the front linkage pipe 151, the left middle linkage sheet 131, the left cushion side plate 141, the rear linkage pipe 152, the right cushion side plate 142 and the right middle linkage sheet 132 form a fixed closed loop, the left front linkage plate 121, the left rear linkage plate 122, the right front linkage plate 123 and the right rear linkage plate 124 are respectively supported at the lower side of the fixed closed loop, the left front linkage plate 121, the left fixed plate 111, the left rear linkage plate 122 and the fixed closed loop form a four-bar linkage mechanism, the right front linkage plate 123, the right fixed plate 112, the right rear linkage plate 124 and the fixed closed loop form a four-bar linkage mechanism, at this time, the lifting motor 171 works and drives the left rear linkage plate 122 or/and the right rear linkage plate 124 to rotate, the left rear linkage plate 122 or/and the right rear linkage plate 124 can realize the actions of two four-bar linkages, causing the fixed closed loop (and in particular the left and right seat cushion side edge plates 141 and 142) to move up and down.
Seat angle adjustment operating mode:
the lifting motor 171 does not work, the left rear linkage plate 122 or/and the right rear linkage plate 124 is/are not driven, and the left front linkage plate 121, the left rear linkage plate 122, the right front linkage plate 123 and the right rear linkage plate 124 are not moved. At this time, the angle adjusting motor 161 works, the angle adjusting motor 161 moves back and forth under the action of the screw rod structure and drives the front linkage tube 151 to rotate, and because the third end 103 of the left middle linkage piece 131 and the sixth end 106 of the right middle linkage piece 132 are respectively connected with the left end and the right end of the front linkage tube 151, the front linkage tube 151 rotates by taking a connecting line between the first end 101 of the left middle linkage piece 131 and the fourth end 104 of the right middle linkage piece 132 as an axis, so as to drive the second end 102 of the left middle linkage piece 131 and the fifth end 105 of the right middle linkage piece 132 to move, and thus the left cushion side plate 141 and the right cushion side plate 142 both rotate along the axis of the rear linkage tube 152, thereby realizing the angle adjustment of the seat.
