Reliable and stable purpose is used for a long time to reach.
In order to solve the above-mentioned technical problem, the technical scheme that the utility model is used for：
The waist support of car seat, including bottom plate and scissor linkage and for the lumbal branch fagging to lumbar support, institute
State lumbal branch fagging to be located on bottom plate by scissor linkage, the bottom plate, which is provided with, to be used to drive scissor linkage bottom two
Hold the pushing motor of relative motion.
Further, the lumbal branch fagging is provided with ear mount with holes and the trough of belt ear for being used for that scissor linkage two ends to be connected
Seat.
The bottom plate is provided with slidable slide plate, and slide plate is located on the push rod of pushing motor, the scissor linkage
Bottom end is located on slide plate, and the scissor linkage bottom other end, which is located at, to be located in the chute on bottom plate.
Relative two edges convex to form slide rail provided with a pair on the bottom plate, and slide plate is located in two projections.
The chute that the scissor linkage bottom other end is provided with T-shaped sliding block, bottom plate is adapted with T-shaped sliding block.
The pushing motor is located on slide plate side, bottom plate is provided with limiting plate in slide plate opposite side.
Compression spring is provided between the slide plate and limiting plate.
The compression spring is a pair, and the axis of push rod is located at the centre of the axis of a pair of compression springs.
The utility model compared with prior art, with advantages below：
The waist support of car seat reasonable in design, drives lumbal branch fagging to move by scissor linkage, is used for a long time
It is reliable and stable to be hardly damaged；There is preferable pooling feature by compression spring driving, to human body back damping of shocks, seat is improved
The comfortableness of chair back.
Brief description of the drawings
The content expressed by each width accompanying drawing of this specification and the mark in figure are briefly described below：
Fig. 1 is the utility model supporting structure schematic diagram.
Fig. 2 is the utility model base arrangement schematic diagram.
In figure：
1. lumbal branch fagging, 2. arch upward shell fragment, 3. ear mounts with holes, 4. trough of belt ear mounts, 5. connecting rods, 6. bottom plates, 7. pushing motors,
8. slide plate, 9. compression springs, 10. slide rails, 11. chutes.
Embodiment
Below against accompanying drawing, by the description to embodiment, further detailed is made to embodiment of the present utility model
Thin explanation.
As depicted in figs. 1 and 2, the waist support of car seat, including bottom plate 6 and scissor linkage and for waist branch
The lumbal branch fagging 1 of support, wherein, lumbal branch fagging 1 is located on bottom plate 6 by scissor linkage, and bottom plate 6 is provided with and cut for driving
The pushing motor 7 of linkage bottom two ends relative motion is pitched, stretches to promote lumbal branch fagging to move by scissor linkage.
Lumbal branch fagging 1, which is provided with, is used for arch upward shell fragment 2 or the spring pad to lumbar support, elastically deformable when back impacts
With pooling feature, comfortableness is improved.
Lumbal branch fagging 1, which is provided with, is used for ear mount with holes 3 and trough of belt ear mount 4 that scissor linkage two ends are connected.Arch upward bullet
Piece or spring pad are located at lumbal branch fagging side, and ear mount with holes and trough of belt ear mount are located at lumbal branch fagging opposite side.Lumbal branch fagging is modeling
Flitch, meets vehicle lightweight requirements.
Bottom plate 6 is provided with slidable slide plate 8, and slide plate 8 is located on the push rod of pushing motor, relative two edges on bottom plate 6
Slide rail 10 is convexed to form provided with a pair, slide plate is located in two projections., the cunning of slide plate spacing to the direction of motion of slide plate by slide rail
Dynamic direction can only along push rod axis direction.
Scissor linkage is two connecting rods being hinged by rotating shaft, and two connecting rod dimensions are identical, and rotating shaft is located at centre
At position；The bottom end of connecting rod 5 of scissor linkage is located on slide plate 8 by bearing pin, the connecting rod bottom of scissor linkage
The other end, which is located at, to be located in the chute 11 on bottom plate 6, in chute 11 slidably.It is preferred that, scissor linkage bottom is another
The chute that end is provided with T-shaped sliding block, bottom plate is adapted with T-shaped sliding block, simple in construction, reliable and stable.
Pushing motor 7 is located on slide plate side, bottom plate is provided with limiting plate in slide plate opposite side.Set between slide plate and limiting plate
There is compression spring 9.Compression spring 9 is a pair, and the axis of push rod is located at the centre of the axis of a pair of compression springs.
Pushing motor works, and the push rod of pushing motor promotes slide plate, so as to drive scissor linkage bottom two ends opposite
Motion, scissor linkage retraction, lumbal branch fagging does not work.When pushing motor does not work, compression spring promotes skateboarding, from
And scissor linkage bottom two ends move toward one another is driven, scissor linkage drives lumbal branch fagging to stretch out, and people's waist is formed
Support.
In vehicle traveling, when people's waist impacts to lumbal branch fagging, damping buffering can be carried out by compression spring, seat is improved
The comfortableness of backrest.And motor formation self-locking is also can control, lumbal branch fagging and scissor linkage are in a fixed position,
Support Position of the different crowd to lumbal branch fagging is met, is now buffered by the shell fragment elastic deformation that arches upward on lumbal branch fagging.
The utility model is exemplarily described above in conjunction with accompanying drawing, it is clear that the utility model implement not by
The limitation of aforesaid way, as long as employing the improvement for the various unsubstantialities that design of the present utility model and technical scheme are carried out,
Or it is not improved by it is of the present utility model design and technical scheme directly apply to other occasions, it is of the present utility model protect
Within the scope of shield.
