The end plastics slide of deformation and dome element be used for a long time it is fragile after abrasion, and after slide abrasion it is larger with slide bar gap
It is also easy to produce abnormal sound.
Utility model content
In view of the shortcomings of the prior art, technical problem to be solved in the utility model is to provide a kind of Seat lumbar, with up to
To the reliable and stable purpose of long-term use.
In order to solve the above-mentioned technical problem, the technical scheme that the utility model is used for：
The Seat lumbar, including be arranged side by side between bottom plate and lumbal branch fagging, bottom plate and the lumbal branch fagging provided with flexible
The Wedge mechanism for being used for driving lumbal branch fagging to move is provided between bar, bottom plate and the lumbal branch fagging, bottom plate, which is provided with, to be used to push away
The pushing motor of dynamic Wedge mechanism.
Further, the Wedge mechanism includes the driven wedge being located on lumbal branch fagging and slidably driven on bottom plate
Dynamic voussoir, the push rod end of pushing motor is provided with push pedal, and push pedal is connected with driving voussoir.
The pushing motor is the motor with auto-lock function.
Skewback mechanism is provided between bottom plate and the lumbal branch fagging, skewback mechanism includes being located on lumbal branch fagging being oriented to skewback
Be located at bottom 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.
Bottom plate and the lumbal branch fagging is flat board, arranged in parallel.
It is connected between the push pedal and driving voussoir by spring.
The skewback mechanism both sides positioned at expansion link corresponding with Wedge mechanism.
The utility model compared with prior art, with advantages below：
The Seat lumbar reasonable in design, by driving voussoir to drive lumbal branch fagging to move, is used for a long time reliable and stable
It is hardly damaged；Impact by spring buffer in push pedal to backrest, improves the comfortableness of backrest；And it is simple in construction, into
This is low.
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 Seat lumbar structural representation.
In figure：
1. the shell fragment that arches upward, 2. lumbal branch faggings, 3. are oriented to skewback, 4. spacing skewbacks, 5. bottom plates, 6. expansion links, 7. driving wedges
Block, 8. pushing motors, 9. push pedals, 10. springs.
Embodiment
Below against accompanying drawing, by the description to embodiment, further detailed is made to embodiment of the present utility model
Thin explanation.
As shown in figure 1, the Seat lumbar, including bottom plate 5 and lumbal branch fagging 2 is arranged side by side, bottom plate 5 and lumbal branch fagging 2 are equal
It is arranged in parallel for flat board, and it is provided with bottom plate and lumbal branch fagging reinforcement.Bottom plate and lumbal branch fagging are plastic plate,
It is lightweight, meet the requirement of vehicle light-weight design.
Expansion link 6 is provided between bottom plate 5 and lumbal branch fagging 2, be can be movable relatively between bottom plate 5 and lumbal branch fagging 2.Bottom plate 5
The Wedge mechanism for being used for driving lumbal branch fagging to move is provided between lumbal branch fagging 2, bottom plate, which is provided with, to be used to promote 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 bottom 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 driving voussoir.Motor is worked, and driving voussoir is promoted by push pedal
Motion, by driving voussoir so as to promote lumbal branch fagging to move, meets to people's lumbar support.
Lumbal branch fagging 5, which is provided with, is used 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 bottom plate 5 and lumbal branch fagging 2, skewback mechanism includes being located at guiding skewback 3 on lumbal branch fagging
Be located at bottom 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
Skewback mechanism improves lumbal branch fagging motion stabilization reliability.
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 bottom plate, compact conformation is easy to arrangement.
It is connected between push pedal 9 and driving voussoir 7 by spring 10.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, backrest is improved
Comfortableness.And by the self-locking of motor, the position of lumbal branch fagging is adjusted, support level of the different crowd to lumbal branch fagging is met
Put, 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.
