Abstract
A kind of steering wheel switch, is direct press type button switch, the inwall of housing is provided with a gathering sill and two guiding ribs, and the outer wall of push rod is then provided with a convex tendon and two grooves, and one_to_one corresponding gathering sill and guiding rib move cooperation respectively; Push rod is also provided with an auxiliary tank, and then corresponding auxiliary bar and this auxiliary tank matched in clearance of being provided with on housing, forms and presses anti-sticking hysteresis buffer structure.Of the present utility model rational in infrastructure, utilize three main muscle, slot fit limit button position, ensure to press the motion in stroke directions smooth and easy, when the Impact direction of button and its direction of motion inconsistent time, matched in clearance due to auxiliary bar, groove leaves certain surplus, can cushioning effect be played, reduce the friction between push rod and housing, effectively can improve the phenomenons such as shift knob clamping stagnation, feel be bad.
Description
Technical field:
The utility model relates to the function control switch that a kind of vehicle steering uses.
Background technology:
The function control switch that vehicle steering is installed generally has direct press type and moving seesaw-type two kinds of forms, and direct press type button, due to reasons in structure, is applied more extensive.General direct press type switch press the motion that guide frame needs to limit completely in horizontal direction, be only retained in the motion of pressing in stroke directions, rock to prevent switch.But when the pressing force direction run-off the straight that switch is subject to or switch, because of stressed, slight deformation occurs, because the position of shift knob limits completely, press guide frame and can produce larger frictional force, press and the phenomenons such as clamping stagnation, action are not smooth, feel is bad easily occur, performance also needs further improvement.
Summary of the invention:
For the deficiencies in the prior art, the utility model provides a kind of rational in infrastructure, presses steering wheel switch of good performance.
The utility model comprises housing and circuit board, circuit board is connected with touch-switch and connector, button is fixed on push rod upper end, this push rod is placed in the mobile cooperation of housing, and the bottom of push rod and the touching of touch-switch correspondence coordinate formation direct press type button switch, the inwall of housing is provided with a gathering sill and two guiding ribs, and the outer wall of push rod is then provided with a convex tendon and two grooves, and one_to_one corresponding gathering sill and guiding rib move cooperation respectively; Push rod is also provided with an auxiliary tank, and then corresponding auxiliary bar and this auxiliary tank matched in clearance of being provided with on housing, forms and presses anti-sticking hysteresis buffer structure.
Of the present utility model rational in infrastructure, utilize three main muscle, slot fit limit button position, ensure to press the motion in stroke directions smooth and easy, when the Impact direction of button and its direction of motion inconsistent time, matched in clearance due to auxiliary bar, groove leaves certain surplus, can cushioning effect be played, reduce the friction between push rod and housing, effectively can improve the phenomenons such as shift knob clamping stagnation, feel be bad.
The utility model is further illustrated below in conjunction with drawings and Examples.

Fig. 2 is the stereogram of push rod.
Fig. 3 is the vertical view of push rod.
Fig. 4 is the stereogram of housing.
Fig. 5 is the vertical view of housing.

Embodiment:
As shown in Figures 1 to 7, circuit board 4 is housed in housing 1, circuit board 4 is connected with touch-switch 5 and connector 6, button 2 is fixed on push rod 3 upper end, this push rod 3 is placed in the mobile cooperation of housing 1, and the bottom of push rod 3 and touch-switch 5 correspondence touching cooperation form direct press type button switch.The inwall of housing 1 is provided with a gathering sill 7 and two guiding ribs 8, and the outer wall of push rod 3 is then provided with a convex tendon 9 and two grooves 10, and one_to_one corresponding gathering sill 7 and guiding rib 8 move cooperation respectively.Push rod 3 is also provided with an auxiliary tank 11, then correspondingly on housing 1 is provided with auxiliary bar 12 and this auxiliary tank 11 matched in clearance, form and press anti-sticking hysteresis buffer structure.
When applying downforce to button 2, power is passed to push rod 3 by button 2, the direction of push rod 3 along pressure under the cooperation of gathering sill 7 and convex tendon 9 and guiding rib 8 and groove 10 moves and presses touch-switch 5, make touch-switch 5 conducting, circuit forms path, is achieved the function of control.After removing the external force of pressing, touch-switch 5 automatically resets, and its reset response power is transmitted in push rod 3, forces push rod 3 to reach initial condition, i.e. function off-state along the muscle groove of guiding moves.If when there is slight deformation because of stressed in the pressing force direction run-off the straight that switch is subject to or switch, namely the Impact direction of button 2 and its direction of motion inconsistent time, because the matched in clearance of auxiliary bar 12 and auxiliary tank 11 leaves certain surplus, cushioning effect can be played, reduce the friction between push rod 3 and housing 1, effectively improve the phenomenons such as shift knob clamping stagnation, feel be bad.
In the present embodiment, the outer wall bottom of push rod 3 is also provided with locating piece 13, and the upper inside wall correspondence of housing 1 is provided with locating button 14 and matches, and formation plays position limiting structure.When the muscle groove of push rod 3 along guiding moves, locating piece 13 contacts bullet height point, i.e. switch initial condition in the spacing arrival of locating button 14.Button 2 is provided with installing hole 15, push rod 3 be provided with buckle 16 and and the engaging of installing hole 15 correspondence, formation button fixed structure, such button is connected more firm with push rod 3.In addition, steering wheel switch be generally left and right mounted in pairs on the steering wheel, the profile of left-right switch can be designed to mutual symmetry, but overall structure or identical.
Claims (3)
1. a steering wheel switch, comprise housing and circuit board, circuit board is connected with touch-switch and connector, button is fixed on push rod upper end, this push rod is placed in the mobile cooperation of housing, and the bottom of push rod and the touching of touch-switch correspondence coordinate formation direct press type button switch, it is characterized by: on the inwall of housing (1), be provided with a gathering sill (7) and two guiding ribs (8), the outer wall of push rod (3) is then provided with a convex tendon (9) and two groove (10) one_to_one corresponding gathering sill (7) and mobile cooperations of guiding rib (8) respectively; Push rod (3) is also provided with an auxiliary tank (11), then correspondingly on housing (1) is provided with auxiliary bar (12) and this auxiliary tank (11) matched in clearance, form and press anti-sticking hysteresis buffer structure.
