Abstract
A kind of steering wheel switch, comprise the two cover switching devices using wire harness assembly circuit to connect, control circuit board and several function button is provided with in the housing of every suit switching device, each function button and the touching of corresponding touch-switch coordinate, one or more in each function button is difunctional seesaw type button, the guiding push rod of two vertical movements is furnished with in housing below difunctional seesaw type button, the top of each guiding push rod and the two ends corresponding matching of difunctional seesaw type button, the bottom of guiding push rod and corresponding touch-switch pressure are touched and are coordinated, form without deflection pressing mechanism.Of the present utility model rational in infrastructure, the pressing actuating force that seesaw type button wherein applies can only vertically be conducted, can not be partial to, active force is all the time perpendicular to touch-switch handle, switch on and off good reliability, and the operational stroke of two functions is consistent about can making moving seesaw-type button, feel is accurate, and the stability of equilibrium of button is also better.
Description
Technical field: the utility model relates to the integral type function control switch that a kind of switching device, particularly vehicle steering use.
Background technology: be all provided with integral type function control switch on many vehicle steerings, enables driver realize various function at steering wheel direct control.Because steering wheel switch is integrated with multiple function button, wherein part can adopt difunctional seesaw type button, and seesaw type button is rotated when pressing, the movement locus pressing compression leg being located at button two ends is made also to be circular arc, pressing compression leg like this occurs eccentric to the application point of below touch-switch along arc track, touch-switch stress point is caused to move, discontinuity, affect the reliability of switch on and off, and two feature operation strokes are inconsistent about making moving seesaw-type button, feel error is large, and the stability of equilibrium of button is not ideal enough.
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 the two cover switching devices using wire harness assembly circuit to connect, control circuit board and several function button is provided with in the housing of every suit switching device, control circuit board is welded with multiple touch-switch, each function button and the touching of corresponding touch-switch coordinate, one or more in each function button is difunctional seesaw type button, remaining is direct press type button, the lower end of direct press type button directly and touch-switch touching cooperation, the guiding push rod of two vertical movements is furnished with in housing below difunctional seesaw type button, the top of each guiding push rod and the two ends corresponding matching of difunctional seesaw type button, the bottom of guiding push rod and corresponding touch-switch pressure are touched and are coordinated, form without deflection pressing mechanism.
Of the present utility model rational in infrastructure, seesaw type button wherein make use of guiding push rod and presses conducting piece as centre, guiding push rod can only move by vertical direction, and the pressing actuating force that button applies can only vertically be conducted, and can not be partial to, lead push rod to the active force of touch-switch all the time perpendicular to touch-switch handle, switch on and off good reliability, touches sensitive, and about can making moving seesaw-type button, the operational stroke of two functions is consistent, feel is accurate, and the stability of equilibrium of button is also better.
The utility model is further illustrated below in conjunction with drawings and Examples.
Accompanying drawing illustrates: Fig. 1 is the main schematic diagram of embodiment.
Fig. 2 is the schematic cross-section at seesaw type button place in Fig. 1.
Fig. 3 is the schematic cross-section at a direct press type button place in Fig. 1.
Fig. 4 is the stereogram of the direct press type button in Fig. 3.
Fig. 5 is the stereogram of the housing in Fig. 3.
Embodiment: as shown in Figure 1 to Figure 3, two cover switching devices use wire harness assembly 4 circuit to connect, control circuit board 2 and several function button is provided with in the housing 1 of every suit switching device, control circuit board 2 is welded with multiple touch-switch 3, each function button and corresponding touch-switch 3 are touched and are coordinated.One or more in each function button is difunctional seesaw type button 5, and remaining is direct press type button 6, the lower end of direct press type button 6 directly and touch-switch 3 touch cooperation.The guiding push rod 7 of two vertical movements is furnished with in housing 1 below difunctional seesaw type button 5, the top of each guiding push rod 7 and the two ends corresponding matching of difunctional seesaw type button 5, the bottom of guiding push rod 7 and corresponding touch-switch 3 are pressed to touch and are coordinated, and form without deflection pressing mechanism.The shape of the housing 1 of the two cover switching devices of the present embodiment is symmetrical, and form overall symmetrical formula layout, more attractive in appearance when installing and using like this, layout is also reasonable.Between each function button on housing 1 surface, interlocking has decoration separator 10, and not only make the ornamental of switch entirety significantly improve, and make each function button spaced, it is clear that operating area divides, and prevents button misoperation.
When pressing one end of difunctional seesaw type button 5, this end rotates the top pressing down guiding push rod 7, and guiding push rod 7 vertically moves down presses conducting by touch-switch 3, realizes controlling corresponding electrical module function.When the operating physical force suffered by button is withdrawn, because touch-switch 3 itself has auto-reset function, therefore under the reseting elasticity effect of touch-switch 3, difunctional seesaw type button 5 is returned to initial condition, and corresponding switching circuit also disconnects simultaneously.
The lower end of direct press type button 6 directly and touch-switch 3 touch cooperation, general passing through when pressing coordinates with the muscle groove structure directing of housing 1, but for larger direct press type button 6, when operating, button stress point easily may not produce motion inclination in center, common muscle groove structure directing cooperation produces frictional force can be comparatively large, possible clamping stagnation impact operation.As shown in Figures 3 to 5, the present embodiment is also provided with vertical cylinder 8 in the lower surface of part direct press type button 6, and in housing 1, correspondence is provided with circular hole 9 and matches, and forms anti-clamping stagnation guide frame.Because the design of column type guide frame, when run-off the straight campaign, belong to dotted line contact movement in theory, can greatly reduce the frictional resistance between ways, ensure that larger direct press type button 6 in operation can not clamping stagnation, operating handle is good.
