Description

Knob-type gating switch balancing device for automobile electrical appliances
Technical field
The present invention relates to automobile equipment, especially relate to a kind of knob-type gating switch balancing device for automobile electrical appliances.
Background technology
On all automobiles (especially offroad vehicle) of home and abroad, all equipped in a large number the car electrics knob-type gating switch, such as air conditioning control switch, 4 wheel driven switch etc. at present.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 arranged, each large automobile production manufacturer of the world all drops into larger fund and the novel car electrics knob-type gating switch of technical force's research and development, but technical pattern is complicated, cost is higher.
Traditional knob-type gating switch generally adopts metal clips, metal swing arm, wire spring+steel ball structure, and the shortcoming of this structure is that cost is high, the processing request precision is high, feel is jerky.When the diameter of car electrics knob-type gating switch during greater than 30mm, satisfy higher positioning accuracy and control comfort and just have larger manufacture difficulty, also there are the following problems: 1, rocking when knob-type gating switch moves in a circle can be larger, and control is rocked very difficult; 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 knob-type gating switch balancing device for automobile electrical appliances.
The object of the present invention is achieved like this:
A kind of knob-type gating switch balancing device for automobile electrical appliances, comprise switch loam cake and switch lower cover, outer surface at the switch loam cake is provided with gear, fin in the outer wall both sides of switch lower cover is 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 at upper reference column, the bottom of switch loam cake, on reference column around evenly be processed with the loam cake fixed card that several are the interval axially-aligned; Be processed with the lower reference column in the upper reference column hole that can be inserted on the reference column in the centre on the gating switch balance body top of circle, inwall on gating switch balance body top is processed with and gets out of the way the 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 comprised 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, the inwall in gating switch balance body bottom is processed with the stopper slot of two symmetries; Inwall at the switch lower cover is 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 in the inboard on the base plate top of switch lower cover and pass circuit board and can carry out spacing interior limited post to stopper slot, 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.
The shape of cross section of upper reference column hole and lower reference column is for the semicircle of locating, preventing toward each other slippage.
Be processed with at the lateral wall of switch loam cake and prevent the anti-slip veins that skids.
The present invention is comprised 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, consisted of 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, so that can not producing, knob-type gating switch do not rock and crosses a shelves phenomenon in operating process.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 knob-type gating switch obtain good feel, elastic arm can provide enough suitable balance damping forces in motion process, so that the manipulation force of knob-type gating switch is even and easy to control.The switch loam cake is installed on the gating switch balance body by upper reference column and lower reference column, and is fixed in four loam cake holddown grooves by four loam cake fixed cards, has so not only played fixation, axially rocking when having reduced simultaneously the rotation of switch loam cake.
Operation principle: by the rotary switch loam cake, the switch loam cake will drive gating switch balance body by upper reference column and lower 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 stopping gear, stopper slot is spacing by interior limited post, so that the circular motion of switch is stopped effectively, can not produce a shelves phenomenon.
The present invention with numerous structure assemblies of conventional knob switch together, integrated level is high, 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 is so that switch is done circular motion when operation, the rolling momentum significantly reduces, operating physical force is even and gear is clear, reaches the manipulation force that meets designing requirement.The present invention is designed to symmetrical structure, can install at 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.
