Abstract

The utility model discloses a high-strength automobile folding key. The high-strength automobile folding key comprises a button (1), an upper cover (2), a torsion spring (3), a cam (5) and a lower cover (6), and is characterized in that a popping and withdrawing positioning mechanism is arranged in the upper cover (2) and the lower cover (6), a positioning block (4) is installed on the upper cover (2), the torsion spring (3) is installed in the button (1), the cam (5) is placed in a rotary groove between the upper cover (2) and the lower cover (6), the button (1) penetrates through the center hole of the cam (5) and enters in a button hole of the upper cover (2), and the positioning block (4) is a metal part. The high-strength automobile folding key is high in strength, resistant to abrasion, high in dimension manufacturing precision, difficult to deform and reliable in positioning, and the service life of the key is prolonged; the overall strength and structural optimization of the key can be improved, force borne by the key acts on the positioning block, thus strength requirements for the upper cover and the lower cover are reduced, manufacturing is facilitated, and cost is saved.

Description

The high-strength vehicle folding key

Technical field

The utility model relates to key, particularly a kind of high-strength vehicle folding key.

Background technology

There is the detent mechanism defect in common folding key:

1. the key positioner structure directly covers and makes on plastic cement, and intensity is not high and location is inaccurate, and the accessory size fluctuation is wayward greatly;

The plastic cement upper cover easy to wear and the distortion.

Summary of the invention

The purpose of this utility model is to provide a kind of high-strength vehicle folding key, and this key has accurate ejection and regains detent mechanism, has reduced the requirement of strength to upper cover and lower cover, has extended the application life of key, is convenient to manufacture and cost-saving.

The purpose of this utility model and solve its technical problem underlying and realize by the following technical solutions: a kind of high-strength vehicle folding key, comprise and An Gai ﹑ Niu Huang ﹑ cam and lower cover Shang Niu ﹑, in upper cover and lower cover, have and eject and regain detent mechanism, described ejection and withdrawal detent mechanism are to load onto locating piece at upper cover, torsion spring is contained in button, cam is placed in the swivelling chute between upper cover and lower cover, button passes in the button hole that the cam center hole enters upper cover, and button has rotated ejection and the withdrawal of key with moving cam under the effect of torsion spring.

Described locating piece is metalwork, and intensity is high, wear-resistant, and the size accuracy of manufacture is high and not yielding.

During use, when button is in while pressing with free state, by ejection and the withdrawal to key of the locating piece that covers on being contained in, position, torsion spring is contained in button key is ejected power is provided, button has rotated ejection and the withdrawal of key with moving cam under the effect of torsion spring, cam is placed in the swivelling chute between upper cover and lower cover, and button passes in the button hole that the cam center hole enters upper cover.

The utility model compared with prior art has obvious advantage and beneficial effect.As can be known by above technical scheme, the utlity model has following advantage:

1. intensity is high, and is wear-resistant, and the size accuracy of manufacture is high and not yielding;

2. location is reliable;

3. extended the application life of key.

The specific embodiment

Below in conjunction with accompanying drawing and preferred embodiment, the high-strength vehicle folding key specific embodiment, structure, feature and effect thereof to according to the utility model proposes, be described in detail as follows.

As shown in Fig. 1-7, a kind of high-strength vehicle folding key, comprise button 1 ﹑ upper cover 2 ﹑ torsion spring 3 ﹑ cams 5 and lower covers 6, in upper cover 2 and lower cover 6, have and eject and regain detent mechanism, described ejection and withdrawal detent mechanism are to load onto locating piece 4 at upper cover 2, torsion spring 3 is contained in button 1, cam 5 is placed in the swivelling chute between upper cover 2 and lower cover 6, button 1 passes cam 5 centre bores and enters in the button hole of upper cover 2, and button 1 completes ejection and the withdrawal of key with moving cam 5 rotations under the effect of torsion spring 3.

Described locating piece 4 is metalworks, and intensity is high, wear-resistant, and the size accuracy of manufacture is high and not yielding.

During use, when button 1 is in while pressing with free state, by ejection and the withdrawal that is contained in the 4 pairs of keys of locating piece on upper cover 2, position, torsion spring 3 is contained in that button 1 is interior to be ejected power is provided key, button 1 completes ejection and the withdrawal of key with moving cam 5 rotations under the effect of torsion spring, cam 5 is placed in the swivelling chute between upper cover 2 and lower cover 6, and button 1 passes cam 5 centre bores and enters in the button hole of upper cover 2.

The utility model can improve the bulk strength of key and the optimization of structure, and the suffered power of key all acts on locating piece, thereby has reduced the requirement of strength to upper cover and lower cover, is convenient to manufacture and cost-saving.

The above, it is only preferred embodiment of the present utility model, not the utility model is done to any pro forma restriction, any technical solutions of the utility model content that do not break away from, according to technical spirit of the present utility model, to any simple modification, equivalent variations and modification that above embodiment does, all still belong in the scope of technical solutions of the utility model.
