The specific embodiment
(formation of key unit)
Fig. 1 (a) and (b) be the vertical view of the related key unit of expression embodiments of the present invention.
Fig. 1 (a) is expression key plate key unit when taking in, and Fig. 1 (b) is the key unit of expression key plate when outstanding.
This key unit 1 is the locking or unblank and the key of the starting of engine etc. of car door lock that is used for vehicle, constitute by upper body 10 and lower case 11 (Fig. 2), during usual the use, shown in Fig. 1 (a), in hollow key plate resettlement section 11a, contain metal key plate 2.During usual the use, do not use key plate 2, come to transmit the index signal of locking or unblanking etc. of the car door lock of vehicle to automobile wireless by the described later no key module 7 (Fig. 2) that is built in key unit 1.
In addition, for key unit 1, under the situation that no key module 7 is failure to actuate because of battery uses up, shown in Fig. 1 (b), from key unit 1 outstanding state, key plate 2 is inserted into the keyhole of the cylinder lock machine that can switch with key plate 2 to the locking and the latch-release of steering wheel for vehicle.
For example, offer the keyway as inside groove on key plate 2, spring 40 described later (Fig. 3) applies elastic force along the A direction shown in Fig. 1 (b) to key plate 2.
Fig. 2 is the exploded perspective view of the formation of the related key unit of expression embodiments of the present invention.
By protuberance not shown in the upper body 10 or recess are embedded in recess not shown in the lower case 11 or protuberance,, lower case 11 and upper body 10 constitute key unit 1 thereby being become one.Lower case 11 will not have key module 7 and will be housed among the no key module resettlement section 11b (Fig. 3 (a)),, rotary part resettlement section 11c supports support unit 5, and rotary part 4 supporting that key plate 2 will be installed is for being rotated.The aftermentioned protuberance that in support unit 5, is arranged at the side be arranged at recess on 11 corresponding of the lower case chimeric after, further support unit 5 is anchored on lower case 11 by screw 6.
No key module 7 is moved by built-in battery, generate the signal that contains lock signal or unlocking signal and identifying information accordingly with the operation of lock button 70 or unlock button 71, and via the receiving system wireless transmission signal that possesses on the built-in sky alignment vehicle.The receiving system that possesses on the vehicle contains the signal of lock signal or unlocking signal and identifying information according to the signal identification that receives, under the consistent situation of the identifying information of identifying information and registration, according to last lock signal or unlocking signal, carry out locking or unblanking of Vehicular door lock etc.
Fig. 3 (a) is the exploded perspective view of the formation of the related key unit of expression embodiments of the present invention, and Fig. 3 (b) is local amplification stereogram.
Make the position of restriction protuberance 3a of release-push 3 consistent with the limiting holes 110a of the bolster 110 of rotary part resettlement section 11c and embed wherein, by 30 pairs of release-pushes 3 of spring to applying elastic force from a side of leaving lower case 11.Spring 30 can use general helical spring or conical helical spring etc.
The support holes 4a of the cylindrical portion perforation rotary part 4 of release-push 3 and the support holes 5a of support unit 5 also are exposed on the external.Restriction protuberance 3a at key plate 2 from the outstanding state of key unit 1 and be accommodated in the recess 4c (Fig. 4) that is embedded in the limiting holes 110a of bolster 110 respectively and is arranged on rotary part 4 back sides under the state of key plate resettlement section 11a, thereby the restriction rotation.Release-push 3 is formed by ABS resin etc.
Rotary part 4 is formed by die cast metal, inserts rotary part 4 by the end with key plate 2, and will sell 41 and insert pin-and-hole 4b and pin-and-hole 2a and make key plate 2 and rotary part 4 integrated.In addition,, key plate 2 can be made separate form for the kind of the key that makes key plate 2 difference according to each individuality changes, but also can key plate 2 and rotary part 4 is integrally formed.
End as the spring 40 of torsion spring is limited in the groove on the support holes 4a next door that is arranged on rotary part 4, and the other end is limited in the groove at the back side that is arranged on support unit 5 (not shown).Spring 40 produces elastic force in the A direction under the state that key plate 2 is given prominence to from key unit 1, along with key plate 2 turns to the state that is contained in key plate resettlement section 11a, spring 40 produces bigger elastic force in Fig. 1 (b) A direction.
After support unit 5 and lower case 11 are chimeric, screw 6 are connected screw through hole 5b and fastening with the screwed hole 113 of lower case 11, thereby support unit 5 is fixed on the lower case 11.
Fig. 4 (a) and (b) be the release-push 3 of the related key unit 1 of expression embodiment of the present invention and the amplification stereogram of rotary part 4 actions.
Shown in Fig. 4 (a), the restriction protuberance 3a of release-push 3 utilizes the elastic force of spring 30 to be embedded into the recess 4c that is provided with at key plate 2 among the support holes 4a of rotary part 4 under the state that key unit 1 is given prominence to.
Shown in Fig. 4 (b), by being pressed into release-push 3 towards the B direction, restriction protuberance 3a embeds limiting holes 110a, is arranged at the recess 4c and chimeric being disengaged that limits protuberance 3a of the support holes 4a of rotary part 4, and key plate 2 is rotated freely.
In addition, in order to be contained at key plate 2 under the state of key plate resettlement section 11a, the restriction protuberance 3a of release-push 3 also can limit the rotation of rotary part 4, and not shown recess is set on rotary part 4.Under this state, the elastic force of spring 40 becomes maximum, if make restriction protuberance 3a remove the restriction of the rotation of rotary part 4 by be pressed into release-push 3 to the B direction, then key plate 2 is to the rotation of A direction, and key plate 2 becomes outstanding state.
According to above-mentioned embodiment, adopt following structure, promptly, support unit 5 is provided with protuberance 50 and 51, and it is chimeric with the recess 111 and 112 of lower case 11 respectively, even so because of spring 40 under the situation that produces the elastic force make parts not maintain the installation site between the parts, the assembler is unnecessary to keep by the mode that suppresses elastic force, and by trip bolt 6 assembling parts easily just.
As long as support unit 5 can then can also be provided with recess with lower case 11 is chimeric except protuberance, protuberance or recess can be single or multiple.At this moment, lower case 11 also is equipped with recess or protuberance accordingly and with its quantity accordingly with the protuberance or the recess of support unit 5.
In addition, support unit 5 can form as one with upper body 10, also can adopt release-push 3, rotary part 4 and support unit 5 etc. are installed in structure on the upper body 10.
In addition, release-push 3 there is no need and must also can prepare other axis of rotation as the axis of rotation of rotary part 4, as long as have with the structure of restriction rotary part 4 rotations such as the chimeric protuberance of the recess of rotary part 4 just passable.
In addition, if the parts of fastening support unit 5 and lower case 11 are not limited to screw 6, also can use rivet and grommet etc.In addition, also can screwed hole be set, the structure that the screw through hole comes fastening support unit 5 and lower case 11 be set in lower case 11 in support unit 5 sides.
In addition, the present invention is not limited to above-mentioned embodiment, not breaking away from technological thought of the present invention or not adjusting in the scope of technological thought of the present invention, various deformation can be arranged.
