Description

Small-size double round hand keeps off switch

Technical Field

The invention relates to the technical field of a hand-held gear combined switch, in particular to a small-sized double-wheel hand-held gear switch.

Background

At present, along with the rapid development of electronic, computer and internet technologies, the intelligent degree of an automobile is higher and higher, various functional configurations of the automobile are more and more, but the functional arrangement space in the automobile body is limited, so that the automobile switch function is required to be more concentrated, a consumer puts forward a new requirement on the operation convenience of the automobile, and the operation and the gear shifting are more convenient when the automobile is driven.

Therefore, the gear shifting mode of the automobile is not only a traditional mechanical gear handle type, but also a knob type, a key type and a hand gear type are developed gradually. The knob type gear shifting switch is generally installed on a platform between a main driver seat and a secondary driver seat, different driving gears are selected by rotating a knob to different angles, and compared with the traditional mechanical gear shifting, the knob type gear shifting switch saves more space, but is easy to cause drivers to confuse gears; the key type gear shifting switch consists of a row of keys arranged at the right front of the main driver, has the advantage of space saving, but has the defect that the driver needs to look at the gear shifting when shifting gears, otherwise, the gear shifting is shifted in a wrong way like a knob type gear shifting switch; the hand-held type gearshift switch is similar to an automobile windscreen wiper switch, is installed at the right rear part of a steering wheel, and compared with the gear shifting mode, the hand-held type gearshift switch saves more space and is more convenient for a driver to operate except for the time that the driver needs certain adaptation.

There are different kinds of bosom gear switch in the market at present, current bosom gear switch has integrated the automatic and keeps off commonly used P, R, N, D and keep off, if increase engine braking again, manual fender/automatic gear switch over, functions such as economic mode and power mode shift key need additional design button or knob, lead to the part quantity of whole handle structure more, the part in limited handle space also can become complicated to be difficult to arrange, handle switch's life also is difficult to obtain guaranteeing, and whole car manufacturing cost also can increase. Therefore, it is necessary to invent a structure of the hand switch assembly that can improve the utilization of the internal space of the handle.

Disclosure of Invention

The invention provides a small-sized double-wheel hand-stopping switch, which aims to solve the problem that the internal space of the hand-stopping switch is insufficient after the number of functions integrated in the hand-stopping switch is increased.

The different rotation angles of the first knob 61 determine that the contact spring piece 72 is contacted with one of the three fan-shaped contacts 73, so that the adjustment of different gears of the engine brake function is realized. Two functional circuits are designed on the same double-sided circuit board 7, so that the space utilization rate of a narrow space in the hand-held switch is improved while the circuit integration degree is improved.

A first button 91 and a second button 92 are arranged at the rightmost end of the whole handle shell, and E/P and A/M functions are realized respectively. First button 91 along the length direction sliding connection of casing at 1 right-hand member of handle upper cover, the left side of first button 91 sets up bracket component 11, bracket component 11 joint is in whole handle casing, as shown in fig. 6, 7, first micro-gap switch 101 and the second micro-gap switch 102 of electric connection circuit board have been installed on the bracket component 11, first micro-gap switch 101 quantity is two, second micro-gap switch 102 quantity is one, two kinds of micro-gap switch distribute with "article" style of calligraphy, still articulated first button 91 on the bracket component 11, conflict respectively on two first micro-gap switch 101 at the both ends of first button 91, be similar to wane button structure, make its wane to equidirectional through pressing first button 91, thereby switch over the EP function. The sliding of the second button 92 triggers the opening and closing of the second microswitch 102, thereby switching the a/M function.

As shown in fig. 1, 8, and 9, the left end of the handle housing is engaged with the shift lever 12, the left edge of the shift lever 12 extends out of the housing and into the seat 18, and passes through the rotating shaft 13 perpendicular to the paper surface, so that the shift lever 12 can swing up and down along the rotating shaft 13, the left end of the shift lever 12 is engaged with the first sleeve 14, the first sleeve 14 is rotatably connected inside the seat 18, and the rotating shaft 141 of the first sleeve 14 is perpendicular to the rotating shaft 141 of the shift lever 12. The shifting rod 12 and the bottom of the first sleeve 14 are respectively clamped with a shifting fork, the lower end of the shifting fork is clamped with an elastic sheet 16, the elastic sheet 16 is a tin bronze elastic sheet 16, a third circuit board 17 is horizontally clamped in a seat body 18, and the elastic sheet 16 is attached to the surface of the third circuit board 17.

The shift fork of 12 bottom joints of driving lever is first shift fork 151, when the driver stirs the handle from top to bottom, first shift fork 151 deflects about, thereby drive flexure strip 16 and slide from side to side on third circuit board 17, flexure strip 16 that first shift fork 151 drove is the flexure strip 16 that leans on the right side as in fig. 9, it has three kinds of different position states, when the handle is normal, first shift fork 151 is in vertical state, flexure strip 16 is located the intermediate position of contact, the handle is stirred upwards, driving lever 12 is close to the one end of first shift fork 151 and is followed pivot 13 downwards, swing right, first shift fork 151 deflects right, flexure strip 16 slides right to the contact, the handle is stirred downwards, first shift fork 151 deflects left, flexure strip 16 slides left to another contact, thereby realize the plus of AMT function and subtract the fender.

When the handle is pushed forwards, the second shifting fork 152 swings forwards and backwards to drive the elastic piece 16 to slide forwards and backwards on the third circuit board 17, the elastic piece 16 driven by the second shifting fork 152 is the elastic piece 16 close to the left side in the figure 9, and the handle also has three different states.

The specific implementation process is as follows:

when the double-wheel hand-catch switch of the invention is operated, the light-shielding ring 8 passes through different numbers and different photoelectric sensors 71 by rotating the first knob 61, thereby realizing the D/N/R switching function. Turning the second knob 62 causes the contact spring strips 72 to contact different sector contacts 73, thereby performing the engine braking function.

The a/M function is implemented by pressing the second button 92 to trigger the second microswitch 102. The E/P function is achieved by toggling the first button 91 to trigger a different first microswitch 101. The position of the first shifting fork 151 is changed by shifting the handle up and down, so that the gear increasing and reducing of the AMT function are realized. The position of the second shifting fork 152 is changed by shifting the handle back and forth, so that the control function of the hydraulic retarder is realized.
