When the cushion height is adjusted, the high-adjustment motor component drives the left rear connecting rod, the right rear connecting rod, the left front lower connecting rod, the right front lower connecting rod, the left front upper connecting rod and the right front upper connecting rod to move, so that five-connecting-rod linkage is realized, and the angle of the cushion can not be passively changed in the height adjustment process.

Description

Cushion adjustment mechanism and seat
Technical Field
The invention relates to the technical field of seats, in particular to a cushion adjusting mechanism with five linkage rods capable of adjusting the height of a seat and the seat.
Background
Four bar linkages are commonly used in height adjustment of car seats, however, they have only a single degree of freedom to move in a fixed path. When a passenger sits on the seat, the distances between thighs and the front end framework of the seat cushion are different due to the fact that the thighs of persons with the same height and different weights are different, so that the pressure born by the thighs is different, and the requirements on comfort of sitting postures are different. Therefore, the existing four-bar mechanism seat cannot meet the requirements of the comfort of people with the same height and different weights when in use.
The CN206049420U discloses a five-link seat height adjusting mechanism, wherein a left side sliding channel connecting plate and a right side sliding channel connecting plate are connected with a vehicle body floor through sliding rails; one ends of the left and right front lower connecting rods are hinged on the left and right side runner connecting plates through bolts, and the other ends of the left and right front lower connecting rods are hinged with one ends of the left and right front upper connecting rods and the left and right side wall plates through bolts; the other ends of the left and right front upper connecting rods are welded with the rotary shaft sleeve, a left welding assembly is formed after welding, and one end of the front cross beam passes through the left and right welding assemblies and is welded with the left and right wall plates; one ends of the left and right rear connecting rods are hinged on the left and right side runner connecting plates through bolts, and after the other ends of the left and right rear connecting rods are welded with the rear cross beam, the rear cross beam is riveted with the left and right side wall plates. The lead screw motor is fixed on the cushion side plate, one end of the lead screw is hinged with the front upper connecting rod, and the motor pushes the front upper connecting rod to rotate, so that the height adjustment of the front end of the cushion is realized.
In the patent, a screw motor is fixed on a side plate of a cushion, and is too close to a dummy, so that the comfort is poor; meanwhile, as the driving mode of the motor screw is pushing, the positions of the screw and the synchronous rod are relatively limited, the whole adjusting stroke is smaller, and the motor screw is only suitable for adjusting the front end of a common cushion and cannot realize zero gravity; when the rear end adjustment is carried out, the mechanism is in a four-bar structure (a fifth bar is locked by a motor) and is generally in a non-parallelogram shape, and in the rear end adjustment process, the included angle between the seat cushion and the horizontal plane is not a constant value (possibly is increased or decreased depending on the lengths of the front and rear bars), so that the angle of the seat cushion can be passively changed; the front cross beam and the front upper connecting rod are rotatable, the front end adjusting motor can only lock one side five connecting rods, and the other side five connecting rods are free, so that the rigidity of the two ends is greatly different. In addition, because the four-bar structure of the seat is highly regulated and various limits (high regulating stroke and connecting bar stress) are met, the length equality of the front connecting bar and the rear connecting bar is difficult to realize, and the seat has the problem that the angle of the seat cushion is passively changed in the height regulating process.

The seat comprises the seat cushion adjusting mechanism.
In the process of adjusting the cushion adjusting mechanism from the initial state to the zero gravity state, the zero gravity motor assembly is used for adjusting the relative angle between the right front lower connecting rod and the right rear connecting rod, and the right rear connecting rod is used for adjusting the position of the rear pipe. The position of the right rear connecting rod is adjusted when the position of the rear pipe is adjusted, the position of the front pipe is adjusted through the non-working high-speed adjusting motor component, the position of the left front upper connecting rod is adjusted through the front pipe and the left cushion side plate, the relative angle between the left front lower connecting rod and the right rear connecting rod is adjusted, and zero gravity angle adjustment is achieved.
In addition, the zero gravity motor in the zero gravity motor assembly is positioned at the upper position on the inner side of the right sliding rail assembly and far away from the gravity center line of the human body, and the comfort in the adjusting process is better. Meanwhile, in the zero-gravity adjusting process, the zero-gravity motor lead screw in the zero-gravity motor component is far away from the synchronous rod, so that the zero-gravity large-angle adjustment can be realized.
When the cushion adjusting mechanism is used for adjusting the cushion height, a high-speed motor component is started (at the moment, the zero-gravity motor component does not work and is similar to a connecting rod to connect a left front lower connecting rod and a left rear connecting rod together), the high-speed motor component is used for realizing the movement of a front pipe and the left rear connecting rod, the front pipe drives a left front upper connecting rod and a right front upper connecting rod to act through a left cushion side plate and a right cushion side plate at the same time, and the left front upper connecting rod and the right front upper connecting rod are driven to act and drive the left front lower connecting rod and the right front lower connecting rod to act; in addition, the left rear connecting rod drives the rear pipe to move, and the rear pipe synchronously drives the right rear connecting rod to move, so that the cushion height is adjusted. In the cushion adjusting process, the left rear connecting rod and the right rear connecting rod change in angle to drive the left front lower connecting rod and the right front lower connecting rod to link, so that the front end and the rear end of the cushion are adjusted in height simultaneously, and the cushion angle is kept unchanged (at the moment, the zero gravity motor assembly cannot be pulled because the right front lower connecting rod and the right rear connecting rod are linked). In the process of adjusting the height of the front end and the rear end of the cushion at the same time, the invention is five-link linkage instead of four-link linkage, thus realizing the height adjustment of the front end and the rear end of the cushion at the same time and keeping the cushion angle unchanged.
Still further, the left and right ends of the synchronizing bar of the invention are fixedly connected with the left front lower connecting rod and the right front lower connecting rod, and the left front lower connecting rod and the right front lower connecting rod are connected together, so that the rigidity of the locking sides of the left front lower connecting rod and the right front lower connecting rod can be transmitted through the synchronizing tube (similar to the relation between the rear tube and the left rear connecting rod and the right rear connecting rod in the rear end adjusting form).
Compared with the prior art, the invention has the following characteristics:
1. the invention can realize the front end adjustment of the cushion and the rear end adjustment of the cushion, and the two adjustment modes can be adjusted together to achieve the zero gravity posture, and can meet the demands of people with different heights on the height of the cushion, thereby improving the comfort.
2. The zero gravity motor component is hinged with the right front lower connecting rod and the right rear connecting rod, is positioned at the position of the inner side of the right sliding rail component, which is close to the lower side of the seat cushion, is far away from the heavy core line of the human body, and improves the comfort while not depending on the sliding rail.
3. The zero gravity motor assembly is directly hinged with the left front lower connecting rod and the left rear connecting rod, so that a motor mounting bracket is saved, and the cost is reduced.
4. The cushion height is adjusted by changing the angles of the left rear connecting rod and the right rear connecting rod, and five connecting rods are linked, so that the adjustment of the rear end of the cushion is realized.

Detailed Description
The invention is further described below with reference to the drawings and detailed description. The following "left" and "right" are seen in the front-side direction from the rear side of the seat.
Referring to fig. 1 to 3, the cushion adjustment mechanism shown in the drawings includes: the left seat side plate 10a, the right seat side plate 10b, the front pipe 20, the rear pipe 30, the left front lower link 40a, the right front lower link 40b, the synchronizing rod 50, the left front upper link 70a, the right front upper link 70b, the left rear link 80a, the right rear link 80b, the zero gravity motor assembly 90, and the high-speed motor assembly 100. Of course, the slide rail assembly, the synchronizing rod 50 and the zero gravity motor assembly 90 can be set according to the needs, and if the cushion does not need to be subjected to zero gravity adjustment, the zero gravity motor assembly 90 can be omitted; the slide rail assembly can also be eliminated if the seat cushion is not required to slide.
The slide rail assembly includes a left slide rail assembly 60a and a right slide rail assembly 60b.
The left and right ends of the front pipe 20 are fixedly connected with the front side of the left cushion side plate 10a and the front side of the right cushion side plate 10b respectively, and are not rotatable; the left and right ends of the rear pipe 30 are hinged to the rear side of the left cushion side plate 10a and the rear side of the right cushion side plate 10b, respectively, so as to be rotatable.
The left front lower connecting rod 40a is hinged on a left front bracket 61a in the left sliding rail assembly 60a and can rotate; the right front lower link 40b is hinged to a right front bracket 61b in the right slide rail assembly 60b to be rotatable. Of course, if a slide rail assembly is not required, the left and right front lower links 40a, 40b may be directly hinged to the floor or body floor.
The left and right ends of the synchronizing lever 50 are fixedly connected with the left front lower link 40a and the right front lower link 40b, respectively, so as not to be rotatable. The rigidity of the front lower link lock sides of the left and right front lower links is thus transmitted through the synchronization tube (similar to the relationship of the rear tube with the left and right rear links in the case of the rear end adjustment form).
The upper end of the left front upper link 70a is hinged to the front side of the left cushion side plate 10a so as to be rotatable, and the lower end of the left front upper link 70a is hinged to the left front lower link 40a so as to be rotatable; the upper end of the right front upper link 70b is hinged to the front side of the right cushion side plate 10b so as to be rotatable, and the lower end of the right front upper link 70b is hinged to the right front lower link 40b so as to be rotatable.
The upper ends of the left and right rear links 80a and 80b are fixedly connected with the left and right ends of the rear pipe 30, respectively, so as not to be rotatable. The lower ends of the left and right rear links 80a and 80b are hinged to the left and right rear brackets 62a and 62b of the left and right slide rail assemblies 60a and 60b, respectively, so as to be rotatable.
If zero gravity adjustment of the seat cushion is desired using the zero gravity motor assembly 90, the zero gravity motor assembly 90 is positioned inside the right side rail assembly 60b adjacent to the right side rail assembly 60b and includes a zero gravity motor 91 and a zero gravity lead screw 92 driven by the zero gravity motor 91 and a zero gravity threaded tube 93 driven by the zero gravity lead screw 92 for telescoping movement. The zero gravity motor 91 is located at an upper position inside the right slide rail assembly 60b and is hinged to the right front lower link 40b, and the end of the zero gravity threaded tube 93 is hinged to the right rear link 80 b.
The high-speed motor assembly 100 is located at a position adjacent to the left side rail assembly 60a inside the left side rail assembly 60a, and includes a high-speed motor bracket 101, a high-speed motor 102, a high-speed screw 103 driven by the high-speed motor 102, and a high-speed screw tube 104 driven by the high-speed screw 103 to perform telescopic movement. The high-speed motor bracket 101 is fixedly connected with the front pipe 20 and can not rotate; the high-speed motor 102 is hinged on the high-speed motor bracket 101 and can rotate; the end of the high-pitch threaded tube 104 is hinged to the left rear link 80 a.
Referring to fig. 20 and 21, when the seat cushion starts to be adjusted from the initial position (if the seat cushion is not at the initial position, the seat cushion is returned to the initial position first) to the zero-gravity position, the zero-gravity threaded tube 93 is driven to move by the zero-gravity motor 91 and the zero-gravity screw 92, and the movement of the zero-gravity threaded tube 93 pulls the right rear link 80b to move around its hinge point with the right rear bracket 62b in the right slide rail assembly 60b, and the right rear link 80b moves while pulling the rear tube 30 to move.
When the zero-gravity motor 91 and the zero-gravity screw 92 drive the zero-gravity threaded pipe 93 to move, the zero-gravity motor 91 also drives the right front lower connecting rod 40b to move around a hinge point between the zero-gravity motor 91 and the right front support 61b in the right sliding rail assembly 60b, and the right front lower connecting rod 40b moves and simultaneously drives the right front upper connecting rod 70b to move; simultaneously, the movement of the rear tube 30 drives the left rear connecting rod 80a to move around the hinge point of the left rear connecting rod 80a and the left rear bracket 62a in the left sliding rail assembly 60a, and the movement of the left rear connecting rod 80a synchronously drives the front tube 20 to move through the high-speed motor assembly 100 (at the moment, the high-speed motor assembly 100 does not work and corresponds to one connecting rod) and the movement of the right front upper connecting rod 70b, so that the front end of the cushion is adjusted, and the cushion is moved from the initial position to the zero gravity position.
The following embodiments are described with respect to the case where the hinge point E between the right rear link 80b and the right rear bracket 62b in the right slide rail assembly 60b is located at a different position from the hinge point F between the end of the zero-gravity threaded tube 93 in the zero-gravity motor assembly 90 and the right rear link 80b, which are mainly occurred in the actual installation process.
Example 1
Referring to fig. 4 to 7, this embodiment is directed to the case where the hinge point E between the right rear link 80b and the right rear bracket 62b in the right slide rail assembly 60b is located at the upper end of the hinge point F between the end of the zero gravity threaded tube 93 in the zero gravity motor assembly 90 and the right rear link 80 b.
In this embodiment, when the cushion height needs to be adjusted, the high-speed motor assembly 100 is started (at this time, the zero-gravity motor assembly does not work, and a connecting rod is similar to one connecting rod to connect the left front lower connecting rod and the left rear connecting rod together), the high-speed motor 102 drives the high-speed screw 103 to rotate, the high-speed screw 103 drives the high-speed threaded pipe 104 to move, the high-speed motor 102 and the high-speed threaded pipe 104 simultaneously drive the front pipe 20 and the left rear connecting rod 80a to move, and the front pipe 20 simultaneously drives the left front upper connecting rod 70a and the right front upper connecting rod 70b to act through the left cushion side plate 10a and the right cushion side plate 10b, and the left front upper connecting rod 70a and the right front upper connecting rod 70b also drive the left front lower connecting rod 40a and the right front lower connecting rod 40b to act; in addition, the left rear connecting rod 80a drives the rear pipe 30 to move, and the rear pipe 30 synchronously drives the right rear connecting rod 80b to move, so that the cushion height adjustment is realized.
In the cushion adjusting process, the angle change of the left rear connecting rod 80a and the right rear connecting rod 80b drives the left front lower connecting rod 40a and the right front lower connecting rod 40b to link, so that the front end and the rear end of the cushion are adjusted in height at the same time, and the cushion angle is kept unchanged (at the moment, the zero gravity motor assembly cannot be pulled because the right front lower connecting rod 40b and the right rear connecting rod 80b are linked). That is, the embodiment is five-link linkage instead of four-link linkage, so that the front end and the rear end of the cushion can be adjusted in height at the same time, and the cushion angle is kept unchanged. At this time, since the left front lower link 40a and the right front lower link 40b are rotated counterclockwise (because the hinge point E between the right rear link 80b and the right rear bracket 62b in the right slide rail assembly 60b is located at the upper end of the hinge point F between the end of the zero gravity threaded tube 93 in the zero gravity motor assembly 90 and the right rear link 80 b), the α value increases, which can compensate for the decrease in α value during the movement of the first four-bar linkage (ad=bc, CD > AB) and the second four-bar linkage (AD < BC) as shown in fig. 7, and cancel the decrease in α value, so that the cushion angle remains unchanged.
When the seat starts to be adjusted from the initial position to the zero gravity position, the zero gravity threaded pipe 93 is driven to move by the zero gravity motor 91 and the zero gravity lead screw 92, and the movement of the zero gravity threaded pipe 93 pulls the right rear connecting rod 80b to move around the hinge point of the right rear connecting rod 80b and the right rear bracket 62b in the right sliding rail assembly 60b, and the right rear connecting rod 80b moves and simultaneously pulls the rear pipe 30 to move.
When the zero-gravity motor 91 and the zero-gravity screw 92 drive the zero-gravity threaded pipe 93 to move, the zero-gravity motor 91 also drives the right front lower connecting rod 40b to move around a hinge point between the zero-gravity motor 91 and the right front support 61b in the right sliding rail assembly 60b, and the right front lower connecting rod 40b moves and simultaneously drives the right front upper connecting rod 70b to move; simultaneously, the movement of the rear tube 30 drives the left rear connecting rod 80a to move around the hinge point of the left rear connecting rod 80a and the left rear bracket 62a in the left sliding rail assembly 60a, and the movement of the left rear connecting rod 80a synchronously drives the front tube 20 to move through the high-speed motor assembly 100 (at the moment, the high-speed motor assembly 100 does not work and corresponds to one connecting rod) and the movement of the right front upper connecting rod 70b, so that the front end of the cushion is adjusted, and the cushion is moved from the initial position to the zero gravity position.
Example 2
Referring to fig. 8 to 9, since the zero gravity motor assembly 90 is not operated when the seat cushion is adjusted in height in accordance with embodiment 1, a link 90a may be used instead of the zero gravity motor assembly 90 in accordance with embodiment 1, and the present invention may be used in a zero gravity function seat. One end of the link 90a is hinged to the right front lower link 40b, and the other end is hinged to the right rear link 80 b. The seat cushion height adjustment method of this embodiment can be seen in embodiment 1.
Example 3
Referring to fig. 10 to 13, this embodiment is directed to the case where the hinge point E between the right rear link 80b and the right rear bracket 62b in the right slide rail assembly 60b and the hinge point F between the end of the zero gravity threaded tube 93 in the zero gravity motor assembly 90 and the right rear link 80b are coaxial in the Y direction.
The seat cushion height adjusting method of this embodiment can be seen in embodiment 1, which adjusts the seat cushion height with the α value unchanged, and is applicable to the third four-bar linkage mode (as shown in fig. 11, ad=bc, cd=ab, with the α value unchanged during the movement of the four-bar linkage) so that the seat cushion angle remains unchanged.
When the seat starts to be adjusted from the initial position to the zero gravity position, the zero gravity threaded pipe 93 is driven to move by the zero gravity motor 91 and the zero gravity lead screw 92, and the movement of the zero gravity threaded pipe 93 pulls the right rear connecting rod 80b to move around the hinge point of the right rear connecting rod 80b and the right rear bracket 62b in the right sliding rail assembly 60b, and the right rear connecting rod 80b moves and simultaneously pulls the rear pipe 30 to move.
When the zero-gravity motor 91 and the zero-gravity screw 92 drive the zero-gravity threaded pipe 93 to move, the zero-gravity motor 91 also drives the right front lower connecting rod 40b to move around a hinge point between the zero-gravity motor 91 and the right front support 61b in the right sliding rail assembly 60b, and the right front lower connecting rod 40b moves and simultaneously drives the right front upper connecting rod 70b to move; simultaneously, the movement of the rear tube 30 drives the left rear connecting rod 80a to move around the hinge point of the left rear connecting rod 80a and the left rear bracket 62a in the left sliding rail assembly 60a, and the movement of the left rear connecting rod 80a synchronously drives the front tube 20 to move through the high-speed motor assembly 100 (at the moment, the high-speed motor assembly 100 does not work and corresponds to one connecting rod) and the movement of the right front upper connecting rod 70b, so that the front end of the cushion is adjusted, and the cushion is moved from the initial position to the zero gravity position.
Example 4
Referring to fig. 14 to 17, this embodiment is directed to the case where the hinge point E between the right rear link 80b and the right rear bracket 62b in the right slide rail assembly 60b is located at the lower end of the hinge point F between the end of the zero gravity threaded tube 93 in the zero gravity motor assembly 90 and the right rear link 80 b.
The seat cushion height adjustment method of this embodiment is substantially the same as that of embodiment 1, except that when the seat cushion height adjustment is performed, the left front lower link 40a and the right front lower link 40b are rotated clockwise (because the hinge point E between the right rear link 80b and the right rear bracket 62b in the right slide rail assembly 60b is located at the lower end of the hinge point F between the end of the zero gravity threaded pipe 93 in the zero gravity motor assembly 90 and the right rear link 80 b), the α value is reduced, and the increase of the α value during the movement of the fourth four-link mode (ad=bc, CD < AB) and the fifth four-link mode (AD > BC) can be offset, so that the seat cushion angle remains unchanged.
When the seat starts to be adjusted from the initial position to the zero gravity position, the zero gravity threaded pipe 93 is driven to move by the zero gravity motor 91 and the zero gravity lead screw 92, and the movement of the zero gravity threaded pipe 93 pulls the right rear connecting rod 80b to move around the hinge point of the right rear connecting rod 80b and the right rear bracket 62b in the right sliding rail assembly 60b, and the right rear connecting rod 80b moves and simultaneously pulls the rear pipe 30 to move.
When the zero-gravity motor 91 and the zero-gravity screw 92 drive the zero-gravity threaded pipe 93 to move, the zero-gravity motor 91 also drives the right front lower connecting rod 40b to move around a hinge point between the zero-gravity motor 91 and the right front support 61b in the right sliding rail assembly 60b, and the right front lower connecting rod 40b moves and simultaneously drives the right front upper connecting rod 70b to move; simultaneously, the movement of the rear tube 30 drives the left rear connecting rod 80a to move around the hinge point of the left rear connecting rod 80a and the left rear bracket 62a in the left sliding rail assembly 60a, and the movement of the left rear connecting rod 80a synchronously drives the front tube 20 to move through the high-speed motor assembly 100 (at the moment, the high-speed motor assembly 100 does not work and corresponds to one connecting rod) and the movement of the right front upper connecting rod 70b, so that the front end of the cushion is adjusted, and the cushion is moved from the initial position to the zero gravity position.
Example 5
