Description

Button of gear shifting handle

Technical Field

The invention belongs to the technical field of automobile parts, and particularly relates to a key of a gear shifting handle.

Background

Along with the development of science and technology, the shift of passenger car at present gradually toward automatic gear and the electronic shift development, and manual fender mechanism is less and less, on the handle that automatic gear and electron were shifted, all has function button such as unblock button (including P button on the handle, UNLOCK button etc.). The key of the gear shifting handle is the place which is most visually seen and sensed by customers, so that the requirements on the clearance between the key and the peripheral parts and the shaking amount of the key are particularly high. The key-press on the present handle mainly is the translation slip mode, for satisfying customer's high standard requirement, in the design process, to the precision requirement of the design of spare part and product just than higher, also corresponding improvement to the requirement of environment, granule impurity gets into the button and peripheral piece's clearance after, arouses the button card easily to die, brings the potential safety hazard scheduling problem (if the P button card can lead to whole car can't remove P and keep off), and the granular impurity that falls into in the clearance also can't get rid of.

Disclosure of Invention

The invention aims to provide a key of a gear shifting handle, which can solve the problem of function failure caused by dust and particle impurities on the premise of controlling the key clearance and shaking amount.

The key of the gear shifting handle comprises the gear shifting handle, a press switch and a key, and is characterized in that the gear shifting handle is provided with a concave part, the press switch is fixedly arranged at one end of the concave part, the other end of the concave part is provided with a rotating shaft, one end of the key is a fulcrum end, the other end of the key is a press end, the fulcrum end is movably arranged on the rotating shaft, the press end is supported on the press switch, and the top end of the side wall of the concave part close to one side of the press end is provided with a limit baffle for limiting the stroke of the press end.

Above-mentioned handle of shifting has adopted the rotary type button rather than the button of translation formula, and the button passes through the revolute pair to be connected with the handle, and when the button was pressed down like this, the clearance between button and the peripheral matching piece (be the limit baffle of concave part) will grow, has dust or particle impurity inside the clearance, when the clearance grow gradually, will break away from the clearance and fall into the inside of concave part to the jamming that the button leads to because of dust or impurity card in clearance department has been solved. In addition, for the structure connected with the rotating shaft, the positioning is completely matched with the rotating shaft by the keys, the gap and the shaking amount are well controlled, and the influence of dust is small. After the key is loosened, the key automatically resets under the action of the elastic force of the press switch, the press end of the key abuts against the limit baffle at the moment, the stroke of the press end of the key is controlled, the concave part is shielded, and dust is prevented or reduced from entering a gap between the press end of the key and the limit baffle and the concave part.

Furthermore, the end face of the limit baffle and the end face of the pressing end of the key are adaptive inclined faces, the inclined faces are inclined from top to bottom towards the outer side of the key gradually, when the key is pressed down, dust in a gap between the pressing end of the key and the limit baffle automatically slides into the concave portion along the inclined faces, and the possibility of accumulating at the gap is reduced.

Furthermore, a downward protruding convex part is arranged below the pressing end of the key, and the bottom of the convex part is a circular arc surface and is abutted against the top surface of the pressing switch. Set up the bottom and be convex part, can make convex part and press the switch's cooperation more smooth, when the button was pressed down, help reducing the frictional force between button and the press the switch to improve user experience.

Furthermore, the convex part is composed of two parallel plates which have the same structure and are arranged at intervals, so that the contact area with the push switch can be reduced, the friction force between the key and the push switch can be reduced, and the possibility of dust accumulation between the convex part and the push switch can be reduced.

Further, the fulcrum end of button is equipped with downwardly extending's pivot connecting portion, and the tip of fulcrum end is equipped with the dust guard that shelters from pivot connecting portion, and above-mentioned dust guard can reduce the possibility that the dust dropped pivot department, avoids the pivot to receive the dust influence and the circumstances of stagnation appears.

Furthermore, the rotating shaft connecting part is composed of two vertical plates, the vertical plates are provided with through holes for the rotating shaft to pass through, the outer side surfaces of the vertical plates are provided with grooves surrounding the through holes, and dustproof sheets used for shielding the through holes are pasted at the positions of the grooves. The dustproof sheet shields the end part of the rotating shaft and the through hole, and the possibility that dust enters the through hole to influence the rotating shaft is thoroughly avoided.

Furthermore, the concave part is provided with a sleeve, and the rotating shaft penetrates through two ends of the rotating shaft in the sleeve and is exposed out of the sleeve; the concave part is provided with arc grooves below two sides of the sleeve, the bottom end of the vertical plate is an arc part matched with the arc grooves, and the bottom end of the vertical plate is matched with the concave part through an arc structure, so that the rotating shaft can be assisted to limit the keys, and the shaking amount of the keys is controlled, and the stability of rotation of the keys during pressing is guaranteed.

The key of the gear shifting handle is designed in a multi-aspect pertinence mode according to the influence of dust, and the problem of function failure caused by dust and particle impurities can be solved on the premise of controlling key gaps and shaking amount.
