Abstract
The key has a moulded plastic head (14) with an internal passage (30) to accept the end (28) of the key shank (12). The shank of the key is fixed in the passage by transverse pins (32) that pass through (24) the moulded plastic head, engaging with notches (34,36) formed on either side of the shank. A compartment (42) is formed inside the moulded key head to accept an electronic circuit (40). This compartment lies parallel to the passage accepting the key shank. A moulded cover (46) clips in place to cover the electronic circuit. The inner part of the cover has a tongue (50) that lies parallel to the key shank. The tongue has a notch (54) on its underside to engage with the upper of the transverse pins when the key is assembled.
Description
The present invention designs a kind of key, is mainly used in to open automotive door and theftproof lock.
Specifically, the present invention relates to a kind of key, it has a shank with injection molding, and dimple is arranged above, the axial end portion of the key bar of will packing in the dimple, key bar is fixed in the dimple with at least one steady pin, steady pin inserts in the shank of the key, and the shank of the key cooperates with the axial end portion of key bar, and a blind hole is arranged on the shank of the key of key, wherein will adorn an electronic component, blind hole is parallel with dimple basically and seal with stopper.
As everybody knows, an element is housed in the shank of the key, as a transmitting set, can remote-control car the opening and lock of lock, the perhaps vitals of telemotor is as oil supply system.
The key bar that constitutes the key working portion can not be plastics, and it is a metallic rod shaped, and its one axial end is inserted in the dimple that for this reason is provided with on the shank of the key.
In order to ensure key bar fixing in the shank of the key, the shape yin-yang match of the shape of dimple horizontal section and key bar horizontal section.But also be provided with key bar is axially fixed in fastening devices in the shank of the key.It is generally horizontal pin, and pin cooperates with the shank of the key and key bar.
The present invention has designed the key of introducing previously, it is characterized by: stopper is fixed in the shank of the key with the steady pin of key bar.
According to another feature of the present invention:
---pin is cylindrical, and it cooperates with semicircle breach on the key bar side edge mouth, is axially fixed in the dimple so that guarantee key bar, stopper shaft is in the openend that is inserted in the hole, semicircle cross sections is arranged on the stopper, and it will cooperate with pin, to guarantee the fixing of stopper;
---it has the detent mechanism of a definite stopper and key bar relative position, and it makes the breach of otch on the stopper and key bar overlap with hole on the shank of the key, so that the ratio that the installation of steady pin is become is easier to;
---stopper is made of the cover plate and the fixing feet of blind hole openend, a horizontal otch is arranged on pin, and it axially is inserted in the shank of the key, between hole and dimple, seating surface in the interior axial end portion of pin and the shank of the key cooperates, so that the relative position between definite stopper and the dimple.
Can understand other characteristics of the present invention and advantage by the following detailed description.For the explanation below understanding better, we will be with reference to following accompanying drawing:
---Fig. 1 is the decomposition axonometric drawing according to key of the present invention;
---Fig. 2 is the axial sectional view of the decomposition of this key;
---Fig. 3 is the axial sectional view of key after installing.
Shown a key 10 of the present invention among these figure.It mainly is made of key bar 12 that constitutes working portion and the shank of the key 14 that constitutes handle.
Equally, key bar 12 can respectively have the groove (not shown) of row on cutting edge limit 26 and last cutting edge 28 under it.Its quantity and shape make key bar 12 have uniqueness.
The axial end portion 29 of key bar 12 is inserted in the corresponding dimple 30 of the shank of the key 14, and key bar 12 is fixed in the shank of the key 14.
Usually, the shank of the key 14 is an injection molding, can form dimple 30 easily like this.The cross section yin-yang match of the cross section of dimple 30 and key bar 12 can be fixed on key bar 12 in the shank of the key 14 securely.
When key is installed, the end 29 of key bar 12 is axially inserted in the dimple 30.Simultaneously, two crosswise fixed straight pins 32 also have been provided with in the hole 24 of the shank of the key 14.
Horizontal half round cut 34,36 on straight pin 32 and 12 times cutting edges 26 of key bar and the last cutting edge 28 matches, to guarantee the axial restraint of key bar 12.
In order to simplify fitting operation, when the axial end portion 29 of key bar 12 pushed up the bottom 38 of dimple 30, half round cut 34,36 will be just in time overlaps with hole 24 on the shank of the key 14.
As we all know, an electronic unit 40 is housed also in the shank of the key 14, it is contained in the blind hole 42.This blind hole 42 forms when injection moulding in the shank of the key 14.
There is an opening 44 in hole 42, and it is opened on an axial end 45 of the shank of the key 14, and blocks with a stopper 46.
According to the present invention, one of steady pin 32 of key bar 12 will be guaranteed stopper 46 fixing on the shank of the key.
For this reason, a cover plate 48 and a pin 50 are arranged on the stopper 46.Cover plate is with the opening 44 of blind hole 42, and pin 50 will be inserted in the shank of the key 14, between dimple 30 and hole 42.
A downside 52 is arranged on the fixing feet 50, and it will contact with cutting edge 28 on the key bar 12, and a horizontal semicircular opening 54 is arranged on the side 52.When the axial end portion 29 of key bar 12 and stopper 46 all installed on the shank of the key 14, the opening 54 of stopper 46 and the breach 36 on the key bar 12 were in aspectant position, and overlapped with one of hole 24 on the shank of the key 14.
For this reason, an axial inner ends 56 is arranged on the pin 50 of stopper 46, it cooperates with seating surface 58 in the shank of the key 14, makes opening 54 be positioned at corresponding 24 places, hole, makes that simultaneously the external surface 60 of cover plate 48 is concordant with the axial end 45 of the shank of the key 14.
As an advantage, pin 50 is between hole 42 and dimple 30, and this layout can reduce the axial length in hole 42 for fixing stopper 46.
And, can also reduce the thickness of the cover plate 48 of sealing opening 44 like this, so that do not disturb or weaken electromagnetic signal by element 40 emission.
In any case the length of pin 50 is less than the axial length of dimple 30, to avoid weakening bar 12 fixing in handle 14.
In the example of describing and introducing, steady pin is independent part, and these steady pins 32 also can be realized with the distortion of the plastics on the shank of the key 14.To on the shank of the key 14, will form two cylindrical holes like this corresponding to the material that constitutes steady pin 32.
