Abstract
The utility model relates to a foldable key of a motor vehicle, which comprises a key body and a key handle. The key handle consists of an upper shell and a lower shell which are fastened mutually, a holding groove for holding a key is inwardly concavely disposed on a side surface of the key handle, the root of the key body is connected with a rotary shaft mechanism, the rotary shaft mechanism consists of a cam and a button mounted in the cam, particularly, a metal rotary shaft support in the shape of an annular column is arranged between the cam and the button, and the rotary shaft support is integrally embedded in the upper shell. Owing to the technical scheme, the structural strength of the key handle is improved by the aid of the additional zinc alloy rotary shaft support, impact force of the rotary shaft mechanism to the upper shell made of plastic materials when the key is quickly sprung outwards is reduced, and the service life of the key is prolonged. In addition, the foldable key of the motor vehicle is simple in structure, convenient in operation and processing and low in production and maintenance costs, and capital investment on equipment is effectively reduced.
Description
Technical field
The utility model relates to a kind of folding key structure, especially a kind of folding key that is used for motor vehicle.
Background technology
Key is the instrument that people are used to unblank, and the motor vehicle key then is to be specifically designed to the instrument of opening car door and retrofire vehicle.If for improving the portable performance of motor vehicle, the various structures of the normal employing of production designer are accommodated in key body among the shank of the key.Commonplace form of structure is, key body is along specific rotating shaft rotation, during non-driving; The key body revolution is accommodated among the preset tank of the shank of the key, and when driving, only needs pressing button; Key body is hit by a bullet out from tank, just can be inserted in the motor vehicle keyhole.The key body performance is outstanding, exotic shape is changeable because of it is easy to take in for this kind motor vehicle key, and is exquisite and attractive in appearance, so be widely used among all kinds of medium-to-high grade motor vehicles.
But mostly the shank of the key part material of at present traditional motor vehicle folding key is plastics; Through after the prolonged and repeated use, the shank of the key part is especially damaged as key body rotating shaft whereabouts easily, causes key turns malfunctioning; Folder function lost efficacy, and had had a strong impact on motor vehicle driving.
The utility model content
The utility model technical problem to be solved is a kind of collapsible motor vehicle key to be provided, to improve the shank of the key folded part intensity, the durability issues of solution folding key.
In order to solve above technical problem; A kind of collapsible motor vehicle key that the utility model provides; Comprise key body and the shank of the key, said the shank of the key is made up of the upper shell and the lower house of mutual fastening, is concaved with the tank of placing key in the side of the shank of the key; The root of said key body links to each other with a rotating shaft mechanism; Said rotating shaft mechanism comprises cam and is installed in the inner button of cam that it is characterized in that: be provided with the rotary shaft rack of a metal ring cylindricality between said cam and the button, said rotary shaft rack one is embedded among the upper shell.
The technical scheme that the utility model further limits is: said cam is socketed in the rotary shaft rack outer ring, with cross-under in the coaxial synchronous rotation of the button of rotary shaft rack inner ring.The said rotary shaft rack of kirsite and the contact surface of cam or button are smooth.In addition, said rotary shaft rack directly upwards is provided with at least two male part, and said upper shell is provided with the attaching slot of corresponding male part quantity and shape, the radial location in upper shell of said rotary shaft rack.
The outstanding effect of using the utility model technical scheme shows as: after this collapsible motor vehicle key has increased the kirsite rotary shaft rack through improvement; Improved the structural strength of the shank of the key; Also reduced simultaneously to rock because of the rotary part that cooperates with it that the rotating shaft mechanism wearing and tearing cause; Prolonged the application life of key, reduced and changed the waste that key causes once more.And the utility model is simple in structure, and is easy to operate, and cost of production is low, and convenient processing effectively reduces the equipment funds input.
Description of drawings
Fig. 1 is the structure exploded perspective view of the utility model motor vehicle key.
Fig. 2 is the local enlarged diagram of rotary shaft rack assembly structure.
The specific embodiment
A kind of collapsible motor vehicle key that the utility model provides; Its structure such as Fig. 1, shown in Figure 2 comprise key body 2 and the shank of the key 1, and wherein the shank of the key 1 is made up of with lower house 12 upper shell 11 of mutual fastening; Be concaved with the tank 111 of placing key in the side of the shank of the key 1; The root 21 of key body links to each other with a rotating shaft mechanism, and this rotating shaft mechanism comprises cam 3 and be installed in its inner button 4 that correspondence is equipped with the torsion spring 5 that matches in the inside of button 4.Wherein between cam 3 and button 4, be provided with the rotary shaft rack 6 of a metal ring cylindricality, these rotary shaft rack 6 one are embedded among the bracket groove 112 of upper shell 11.
Wherein rotary shaft rack 6 footpath upwards is arranged with two male part 61, and simultaneously, upper shell 11 is provided with should male part quantity and two attaching slots 1121 of shape, rotary shaft rack 6 radial location in upper shell 11.During installation cam 3 is socketed in the outer ring of rotary shaft rack 6, and realizes coaxial synchronous rotation at the button 4 of rotary shaft rack 6 inner rings with cross-under.
After having increased the kirsite rotary shaft rack through improvement; Improved the intensity of the shank of the key; Effectively cushioned the bump impulse force of key At time of eject; Also reduced simultaneously to rock, prolonged the application life of key, reduced and changed the waste that key causes once more because of the rotary part that cooperates with it that the rotating shaft wearing and tearing cause.And the utility model is simple in structure, and is easy to operate, and cost of production is low, and convenient processing effectively reduces the equipment funds input.
Except that the foregoing description, the utility model can also have other embodiments.All employings are equal to the technical scheme of replacement or equivalent transformation formation, all drop on the protection domain of the utility model requirement.
