Description
Technical field
The present invention relates to automobile equipment, especially relate to a kind of car electrics knob gating switch bascule.
Background technology
On all automobiles (especially offroad vehicle) of home and abroad, all equipped car electrics knob gating switch in a large number, at present as air-conditioning control switch, 4 wheel driven switch etc.Raising along with technical development and people's quality of the life, current user vehicle to the location readability of this type of switch, control submissive degree higher requirement all arranged, each big automobile production manufacturer of the world all drops into big fund and the novel car electrics knob gating switch of technical force's research and development, but technical pattern complexity, cost are higher.
Traditional knob gating switch generally adopts metal clips, metal swing arm, wire spring+steel ball structure, and the shortcoming of this structure is that cost height, processing request precision height, feel are jerky.When the diameter of car electrics knob gating switch during greater than 30mm, satisfy high orientation precision and control comfort and just have bigger manufacture difficulty, also there are the following problems: 1, rocking when the knob gating switch moves in a circle can be bigger, and very difficulty is rocked in control; 2, operating physical force is inhomogeneous when rotary switch moves in a circle; 3, the gating gear is unintelligible.
Summary of the invention
The object of the present invention is to provide and a kind ofly do that circular motion when operation rolling momentum significantly reduces, operating physical force is even and gear is clear, integrated level is high, handling ease, good hand touch, simple and reliable, high performance car electrics knob gating switch bascule.
The object of the present invention is achieved like this:
A kind of car electrics knob gating switch bascule, comprise switch loam cake and switch lower cover, outer surface at the switch loam cake is provided with gear, on the fin of the outer wall both sides of switch lower cover, be processed with by screw the switch lower cover is fixed on installing hole on the car body, feature is also to comprise the gating switch balance body that is assemblied in the switch lower cover, in the middle of the bottom of switch loam cake, be processed with reference column, be provided with the reference column hole on the last reference column, the bottom of switch loam cake, on reference column around evenly be processed with several and be the loam cake fixed card of axially-aligned at interval; The centre on the gating switch balance body top of circle be processed with can be inserted on the reference column on following reference column in the reference column hole, on the inwall on gating switch balance body top, be processed with and get out of the way loam cake fixed card insertion of closing loam cake and the loam cake holddown groove of locating, the elastic arm of " L " shape that two shapes are identical is made up of transverse arm and perpendicular arm, the equal symmetry in the bottom of two transverse arms is fixed on the outer wall of gating switch balance body, be provided with the stop position of arc at the outer wall of two transverse arms, be provided with the location curved surface of arc on the top of two unsettled perpendicular arms, on the inwall of gating switch balance body bottom, be processed with the stopper slot of two symmetries; On the inwall of switch lower cover, be processed with the location notch that several cooperate with the location curved surface on the perpendicular arm top of elastic arm, circuit board is installed in the middle of the base plate top of switch lower cover and is processed with and pass circuit board and can carry out spacing interior limited post, be processed with and carry out spacing outer limited post to the stop position of transverse arm outer wall in the outside on the base plate top of switch lower cover to stopper slot in the inboard on the base plate top of switch lower cover.
The shape of cross section of last reference column hole and following reference column is the semicircle that is used to locate, prevent slippage toward each other.
Be processed with at the lateral wall of switch loam cake and prevent the anti-skidding line that skids.
The present invention is made up of switch loam cake, gating switch balance body and switch lower cover, between the loam cake holddown groove of the loam cake fixed card of switch loam cake and gating switch balance body, between the interior limited post of the stopper slot of gating switch balance body and switch lower cover, constituted position limiting structure between the outer limited post of the stop position of the elastic arm of gating switch balance body and switch lower cover, make the knob gating switch in operating process, can not produce and rock and cross a shelves phenomenon.Three location notchs motions on the inwall of the location curved surface cooperation switch lower cover on the perpendicular arm top of elastic arm, can make the knob gating switch obtain good hand feeling, elastic arm can provide enough suitable balance damping forces in motion process, make that the manipulation force of knob gating switch is even and easy to control.The switch loam cake is installed on the gating switch balance body by last reference column and following reference column, and is fixed in four loam cake holddown grooves by four loam cake fixed card, has so not only played fixation, axially rocking when having reduced the rotation of switch loam cake simultaneously.
Operation principle: by the rotary switch loam cake, the switch loam cake will drive gating switch balance body by last reference column and following reference column and rotate together, realizes the gating shift function.In the rotary movement of switch loam cake and gating switch balance body, when rotating to initial gear, the stop position is spacing by outer limited post; When rotating to the termination gear, stopper slot is spacing by interior limited post, makes that the circular motion of switch is stopped effectively, can not produce the shelves phenomenon.
The present invention integrates numerous structures of conventional knob switch, the integrated level height, and dependable performance, mould is simple and easy to realize that it adopts nylon material, low, the easy to control parameter of cost, lubrication property are good.These advantages all are that the conventional knob switch does not possess.The present invention can be according to the size of the switch loam cake of reality, adjust the length of two elastic arms, provide enough suitable balance damping forces by elastic arm, the result makes when switch is done the circular motion operation, the rolling momentum significantly reduces, operating physical force is even and gear is clear, reaches the manipulation force that adheres to specification.The present invention is designed to symmetrical structure, can install on 0 degree or 180 degree both directions during assembling, and is simple and reliable, practical.
Therefore, the present invention have that the circular motion of work when operation rolling momentum significantly reduces, operating physical force is even and gear is clear, integrated level is high, handling ease, quick for installation, good hand touch, simple and reliable, practical, low-cost, high performance advantage.
