Abstract
A kind of steering wheel switch, comprise housing and control circuit board, surface of shell is distributed with several button, and button and housing guiding coordinate, and control circuit board is connected with several touch-switch, the inside of each button is equipped with pushing block, the cross section of pushing block is T-shaped, and pushing block is positioned at the position of keeping to the side of button, and corresponding touch-switch is positioned at pushing block can touch place, also be provided with T-slot and pushing block matched in clearance in housing, form anti-clamping stagnation and assist guide frame.Of the present utility model rational in infrastructure, the pushing block of T-shaped can reliably touch pressing touch-switch, and touch-switch is without the need to just to button, many buttons are strengthened greatly at the layout flexibility on switch surface, the design of switch integral form is restricted few, and structure can be compacter, and volume is less.And the T-slot of housing and the matched in clearance of pushing block leave certain surplus, also can play cushioning effect when button discontinuity, effectively improve the phenomenons such as shift knob clamping stagnation, abnormal sound.
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 installed on vehicle steering more employing direct press type button, usually muscle groove guiding fit structure is adopted between direct press type button and housing, button generally needs to arrange certain precompressed to ensure operating handle, for avoiding button the phenomenons such as clamping stagnation, abnormal sound, switch press are unreliable to occur depressing in advance due to discontinuity, and the touch-switch that the touching of button correspondence coordinates must be arranged on immediately below button.But in practice, the specific requirement such as profile, the size change of steering wheel switch is more, and the relative position of touch-switch and button fixes the flexible topology that greatly can limit multiple button, makes the design of switch integral form be subject to obvious impact, spatial volume is large, and structure is not compact.
Summary of the invention: for the deficiencies in the prior art, the utility model provides a kind of rational in infrastructure, compact steering wheel switch.
The utility model comprises housing and control circuit board, surface of shell is distributed with several button, button and housing guiding coordinate, control circuit board is connected with several touch-switch, the inside of each button is equipped with pushing block, the bottom of each pushing block and the touching of each touch-switch correspondence coordinate formation direct press type button switch, the cross section of pushing block is T-shaped, and pushing block is positioned at the position of keeping to the side of button, corresponding touch-switch is positioned at pushing block can touch place, also be provided with T-slot and pushing block matched in clearance in housing, form anti-clamping stagnation and assist guide frame.
Of the present utility model rational in infrastructure, the pushing block of T-shaped can reliably touch pressing touch-switch, and touch-switch is without the need to just to button, many buttons are strengthened greatly at the layout flexibility on switch surface, the design of switch integral form is restricted few, and structure can be compacter, and volume is less.And the T-slot of housing and the matched in clearance of pushing block leave certain surplus, also can play cushioning effect when button discontinuity, effectively improve the phenomenons such as shift knob clamping stagnation, abnormal sound.
The utility model is further illustrated below in conjunction with drawings and Examples.
Accompanying drawing illustrates: Fig. 1 is the main structure schematic diagram of embodiment.
Fig. 2 is the stereogram of embodiment.
Fig. 3 is the stereogram of a button.
Fig. 4 is the bottom view of Fig. 3.
Fig. 5 is the stereogram of housing.
Embodiment: as shown in Figures 1 to 5, control circuit board 4 is housed in housing 1, housing 1 surface distributed has several button 2, button 2 and housing 1 lead and coordinate, control circuit board 4 is connected with several touch-switch 3, the inside of each button 2 is equipped with pushing block 5, and the bottom of each pushing block 5 and the touching of each touch-switch 3 correspondence coordinate formation direct press type button switch.The cross section of pushing block 5 is T-shaped, and pushing block 5 is positioned at the position of keeping to the side of button 2, and corresponding touch-switch 3 is positioned at pushing block 5 can touch place, is also provided with T-slot 6 and pushing block 5 matched in clearance, forms anti-clamping stagnation and assist guide frame in housing 1.
When applying downforce to button 2, button 2 presses touch-switch 3 by pushing block 5, makes touch-switch 3 conducting, and circuit forms path, is achieved the function of control.After removing the external force of pressing, touch-switch 3 automatically resets, and its reset response power is transmitted on button 2, forces button 2 moves to reach initial condition, i.e. function off-state.If when the pressing force that switch is subject to uneven and direction run-off the straight or slight deformation, namely the Impact direction of button 2 and its direction of motion inconsistent time, because the matched in clearance of pushing block 5 and T-slot 6 leaves certain surplus, cushioning effect can be played, reduce friction, effectively improve switch and press the phenomenon such as clamping stagnation, abnormal sound.
The inside of the button 2 in the present embodiment is provided with several convex tendons 7, and in housing 1, correspondence is provided with gathering sill 8 and matches, and forms muscle groove guide frame, presses action-oriented simple and stable like this.Some larger button 2, when operating, stress point easily may not produce motion inclination in center, common muscle groove guiding cooperation produces frictional force can be larger, this button 2 need not adopt muscle groove guide frame, the lower surface of button 2 can be provided with cylinder, in housing 1, correspondence is provided with circular hole and matches, and the column type guide frame frictional resistance of formation is less.
The present embodiment is provided with printing opacity mark 9 on the surface of button 2, so only on control circuit board 4, correspondence need be connected with miniature bulb, during circuit turn-on, light can appear, and function instruction is more obvious.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 control circuit board, surface of shell is distributed with several button, button and housing guiding coordinate, control circuit board is connected with several touch-switch, the inside of each button is equipped with pushing block, the bottom of each pushing block and the touching of each touch-switch correspondence coordinate formation direct press type button switch, it is characterized by: the cross section of pushing block (5) is T-shaped, and pushing block (5) is positioned at the position of keeping to the side of button (2), corresponding touch-switch (3) is positioned at pushing block (5) can touch place, T-slot (6) and pushing block (5) matched in clearance is also provided with in housing (1), form anti-clamping stagnation and assist guide frame.
