In order to solve the above-mentioned technical problem, the technical solution adopted in the present invention is：
This is used for the waist support of seat, including base plate and lumbal branch fagging is arranged side by side, and is set between the base plate and lumbal branch fagging
There is expansion link, the Wedge mechanism for driving lumbal branch fagging to move is provided between the base plate and lumbal branch fagging, base plate is provided with
Pushing motor for promoting Wedge mechanism；The lumbal branch fagging is provided with for arch upward shell fragment or the spring to lumbar support
Pad；Arch upward shell fragment or spring pad is located at lumbal branch fagging side, and Wedge mechanism is located at lumbal branch fagging opposite side.
Further, the Wedge mechanism includes the driven wedge being located on lumbal branch fagging and is slidably driven on base plate
Dynamic voussoir, the push rod end of pushing motor is provided with push pedal, and push pedal is connected with voussoir is driven.
The pushing motor is the motor with auto-lock function.
Skewback mechanism is provided between the base plate and lumbal branch fagging, skewback mechanism includes being located on lumbal branch fagging being oriented to skewback
Be located at base plate upper limit skewback, be located at be oriented to skewback on inclined-plane be adapted with the inclined-plane being located on spacing skewback.
The base plate and lumbal branch fagging are flat board, arranged in parallel.
The base plate and the equal plastic plate of lumbal branch fagging, and reinforcement is provided with plastic plate.
It is connected by spring between the push pedal and driving voussoir.
The skewback mechanism both sides positioned at expansion link corresponding with Wedge mechanism.
The present invention compared with prior art, with advantages below：
The waist holder structure that this is used for seat is reasonable in design, drives lumbal branch fagging to move by driving voussoir, and long-term use is steady
Fixed reliability is hardly damaged；Impact by spring buffer in push pedal to backrest, improves the comfortableness of backrest；And structure letter
It is single, low cost.
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 waist holder structure schematic diagram of the present invention.
In figure：
1. arch upward shell fragment, 2. lumbal branch fagging, 3. guiding skewback, 4. spacing skewback, 5. base plate, 6. expansion link, 7. driving wedge
Block, 8. pushing motor, 9. push pedal, 10. spring.
Specific embodiment
Below against accompanying drawing, by the description to embodiment, further details of is made to specific embodiment of the invention
Explanation.
As shown in figure 1, this is used for the waist support of seat, including base plate 5 and lumbal branch fagging 2, base plate 5 and waist supporting is arranged side by side
Plate 2 is flat board, arranged in parallel, and is provided with reinforcement on base plate and lumbal branch fagging.Base plate and lumbal branch fagging are modeling
Flitch, it is lightweight, meet the requirement of vehicle light-weight design.
Expansion link 6 is provided between base plate 5 and lumbal branch fagging 2, be can be movable relatively between base plate 5 and lumbal branch fagging 2.Base plate 5
The Wedge mechanism for driving lumbal branch fagging to move is provided with and lumbal branch fagging 2 between, base plate is provided with for promoting Wedge mechanism
Pushing motor 8.
Wedge mechanism includes the driven wedge being located on lumbal branch fagging 2 and the slidable driving voussoir 7 on base plate 5, pushes away
The push rod end of dynamic motor 8 is provided with push pedal 9, and push pedal 9 is connected with voussoir is driven.Motor works, and is promoted by push pedal and drives voussoir
Motion, promotes lumbal branch fagging to move by driving voussoir, meets to people's lumbar support.
Lumbal branch fagging 5 is provided with for arch upward shell fragment 1 or the spring pad to lumbar support.Arch upward shell fragment 1 or spring pad
In the side of lumbal branch fagging 5, Wedge mechanism is located at lumbal branch fagging opposite side.In vehicle traveling, when people's waist impacts to lumbal branch fagging,
Arch upward shell fragment or spring pad elastic deformation buffering, improves the comfortableness of backrest.
Pushing motor 8 is the motor with auto-lock function.The position of push pedal 9 is limited by the auto-lock function of motor, from
And the adjusting position of lumbal branch fagging is limited, compact conformation, without other position limiting structures, is easy to arrangement.
Skewback mechanism is provided between base plate 5 and lumbal branch fagging 2, skewback mechanism includes being located at guiding skewback 3 on lumbal branch fagging
Be located at base plate upper limit skewback 4, be located at be oriented to skewback 3 on inclined-plane be adapted with the inclined-plane being located on spacing skewback 4.Pass through
Lumbal branch fagging motion stabilization reliability improves in skewback mechanism.
The skewback mechanism both sides positioned at expansion link 6 corresponding with Wedge mechanism.Skewback mechanism and Wedge mechanism are located at lumbal branch
Between fagging and base plate, compact conformation is easy to arrangement.
It is connected by spring 10 between push pedal 9 and driving voussoir 7.Spring 10 is a pair, and two springs are respectively provided at push pedal
Two ends.
In vehicle traveling, when people's waist impacts to lumbal branch fagging, damping buffering can be carried out by spring, improve backrest
Comfortableness.And the self-locking for passing through motor, adjusts the position of lumbal branch fagging, meets support level of the different crowd to lumbal branch fagging
Put, now buffered by the shell fragment elastic deformation that arches upward on lumbal branch fagging.
The present invention is exemplarily described above in conjunction with accompanying drawing, it is clear that the present invention is implemented and do not receive aforesaid way
Limitation, if employ the improvement of various unsubstantialities that design of the invention and technical scheme are carried out, or it is not improved will
Design of the invention and technical scheme directly apply to other occasions, within protection scope of the present invention.
