Description
Technical field
The invention belongs to automotive seating art fields, refer in particular to a kind of with the seat angle adjustors for driving control panel more.
Background technique
Traditional angle adjustor includes gear ring, guide plate, cam and locking device.Gear ring has receiving recessed on its inner surface
It falls into, interior form of gear tooth is in the marginal portion for accommodating recess.Guide plate is connected to the inner surface of gear ring, interior table of multiple guide blocks from guide plate
Face protrusion.Two opposite guide blocks define locking device guiding recess.Cam is placed between guide plate and gear ring, and cam exists
Its center is cased with control stick rotary shaft.External gear teeth is formed on the outer peripheral surface of each locking device.
In traditional angle adjustor with above structure, when control stick rotary shaft rotates in the clockwise direction, along behaviour
The outside that the both ends of the cam of vertical pole rotary shaft rotation push locking device to be radially orientated guide plate is mobile.To locking device edge
Corresponding guiding recess movement, thus the interior gear teeth meshing of the external gear teeth of locking device and gear ring, hence into lock state.
However, in traditional angle adjustor, since each locking device guides recess sliding along corresponding locking device
Architectural characteristic, to ensure the gap of movement of locking device be formed in the two side walls of locking device in corresponding guide block
Between surface, guide block limits the locking device between guide block and guides recess.Further, since locking device is led along locking device
Draw the sliding of recess repeatedly, since the friction between the two side walls of locking device and the inner surface of guide block causes to fill in locking
In the two side walls set on the inner surface of guide block generate abrasion.Therefore, with the increase of the access times of the angle adjustor,
Gap between locking device and guide block is gradually increased, and causes backrest around the unnecessary movement of rotary shaft, in addition angle adjustor
Manufacturing tolerance, so as to cause the decline of angle adjustor locking intensity, Yi Yinfa safety accident.
In addition, being applied to the force localization point of each locking device due to external force when external force is when angle adjustor
It is distributed on the side wall of one of guide block on the two sides of locking device, thus, so that guide block is easily deformed.Once guide block generates
Deformation, the gap between locking device and guide block just increases.Locking device can not be at a fully engaged with gear ring, is easy to send out in automobile
It is detached from locking when raw collision or emergency brake, causes accident.
Chinese invention patent CN102292238A discloses a kind of " angle adjustor of vehicle seat ", and the angle adjustor of the vehicle seat includes
Gear ring, guide plate, control stick rotary shaft, cam, elastic component, main control unit, locking device and locking device supporting element.The gear ring
With the interior gear teeth.The guide plate, which is incorporated on the gear ring and the guide plate, has guide block.Control stick rotary shaft passes through described
Guide plate and gear ring insertion.The cam has support protrusion on its both ends.Bullet is provided on the inner surface of the guide plate
Property supporting element, each elastic component is elastically supported in the first end of the corresponding support protrusion.The main control unit and institute
State cam combination.Interior guide hole and outer guide hole are formed through the main control unit.The locking device is slidably disposed on phase
To guide block between, and each locking device have support recesses.The support recesses have concave curved surface and convex surface.Foreign steamer
Tooth is formed on each locking device.Each locking device supporting element has the first contact surface, the second contact surface and Nei Biao
The concave curved surface in face, first contact surface and the support recesses is in close contact, second contact surface and corresponding
The guide block be in close contact, the both ends of the inner surface are by the cam support.
In above scheme, when the angle adjustor of vehicle seat is in the lock state, the both ends of the inner surface of locking device supporting element
It maintains by the state of the outer peripheral surface support of cam.Therefore, above scheme can prevent locking device and locking device supporting element it
Between and locking device and be disposed adjacent to locking device supporting element both ends guide block inner surface between form gap.Cause
And when angle adjustor is in the lock state, it can prevent lazyback from unnecessarily moving around rotary shaft, to enhance product
Reliability.
But the supports support of above scheme, in locking device bottom, supporting element inner surface is again by cam support, therefore
Mechanism is complex, manufacturing tolerance and abrasion generate error overlay error increase, also result in locking device and gear ring without
Method is at a fully engaged, is easy to collide in automobile or when emergency brake is detached from locking, initiation accident causes sealed.
Summary of the invention
