The specific embodiment

Key according to the invention here is as use the switching device that waits lock such as automobile.Specifically, this key can be used to door leaf (car door, luggage case ...), ignition switch and steering wheel carry out lock and unlock.

This key, symbol 1 is installed in the shell 2, so that rotate between stowed position in shell side face recess 3 and the extended position, this key 1 extends 180 ° with respect to its stowed position on extended position.The shell 2 here has a base 4 that is covered by cover 5, and comprises the electronic module of remote control here.

With known method itself, the CCU of the lock and unlock of straighforward operation automobile door leaf (car door, luggage case).Key 1 comprises the end 6 in the lock core symbol 7 that is fixed on, and is installed in the side recess 3 between the shell 2 side faces 20, so that between the extended position of this key 1 and stowed position, rotate.Lock core 7 has two parallel reciprocal external surfaces 8,9.Lock core 7 comprises groove 10, the latter have with key 1 vertically and the vertical axis 11 of external surface 8,9.Groove 10 presents circular cross section, and reaches

external surface

8,9.

Ditch 12 is arranged in the groove 10.Form an about angle [alpha] of 170 ° between two ditches 12.This staggers less than 180 ° angle, can avoid any one ditch and lock core 7 to overlap to the area part of the transfer of key 1 end 6, but the lock core 7 that has a relative compact simultaneously.

Per pass ditch 12 all comprises one section inlet 13, the external surface 8 of its 13.1 sensible lock core 7 through the end, and end of warp 13.2 sensible one section closed end 14.

This section inlet 13 is L-shaped here, and a part of in other words end 13.1 extends in parallel with axis 11, and a part of end 13.2 is along the circumference extension of groove 10.Part end 13.2 here side direction only is positioned at external surface 8 side on one side and is limited, so that simplify the manufacturing (back also will be explained) of lock core 7.

This section end 14 is parallel to axis 11 and extends, and with key 1 from its stowed position the order to the direction of its extended position rotation, be positioned at the back of a part of end 13.1.This section end 14 has a side 28, and this side is relative with end 13.2, and can in groove, extend vertically.

The pivot of groove 10 bound symbols 16 of lock core 7 and the control button of a symbol 17 have a spring 18 to extend (this spring 18 is visible on Fig. 1, but too loaded down with trivial details for fear of this figure, on Fig. 6, does not illustrate) between them.

Pivot 16 outer shape are cylindrical, have circular profile, and have opened

end portions

19,21, rotatably are connected in the groove of shell 2 side faces 20.Pivot jointed shaft of 16 definition and lock core 7 are with respect to the axis of rotation of shell 2.This jointed shaft and axis of rotation overlap with axis 11.Pivot 16 is here processed with metal.

Control button 17 has a cylindrical outer surface, and the one of which end has the section of stretching out 22 and can stretch vertically, and cooperates with lock core 10, and some can stretch opposite end 23 in from groove 10, and passes the hole of cover 5.

End 22 is received within the stopper slot 30 that is arranged in being arranged in pivot 16 ends 19 and cooperates, and can be parallel to axis 11 slippages.Stopper slot 30 has a width with end 22 joins and width, adjusts to the width of part 22, so that be restricted to minimum to the angular clearances between pivot 16 and the control button 17.The parallel sided of stopper slot 30 and end parts 22 is in the glide direction (being parallel to axis 11 in other words) of control button 17.So, the rotation that in rotation, links together of control button 17 and pivot 16.Protruding pin 24 all is equipped with on one on every limit in this end 22.Two protruding pins 24 on angle that. this staggers 170 °, and is received within during this section end 14 of ditch 12 cooperates, so that between the stuck position of lock core 7 rotations and lock core 7 rotation off-positions, slide.On stuck position, two protruding pins 25 engage with 180 ° two stopper slots 26 of staggering each other, and stopper slot is positioned near the hole of cover 5 on the

side face

2, and 23 radially flared end reduction of area advances protruding pin along the end.On the rotation off-position of lock core 7, control button 17 is pressed, and protruding pin 25 is deviate from from stopper slot 26.

Control button 17 here is injection molding with thermoplastic.

Spring 18 ends are fixed in the control button 17, can not in shell 2, rotate.Control button 17 comprises an otch 27 here, admits spring 18 respective end portions, to prevent that this end is with respect to button rotation.Spring 18 opposite ends withstand the internal edge of end 19 and pivot 16, and pivot 16 embeds the ditch 29 that is arranged in from the pin that corresponding side face 20 protrusions in the inside of pivot 16 ends 19 extend.Spring 18 is coil springs, makes control button 17 get into its stuck position through compressive force.In addition, when lock core 7 was in the stowed position, this spring 18 received the distortion with respect at least 180 ° of its inactive states.So spring 18 keeps protruding pin 24 to withstand the side of end 14 through distortion power simultaneously, and makes lock core 7 be in the extended position of key 1.

The control button 17 that is in its stuck position when being noted that work guarantees, no matter lock core 7 is in the extended position of key 1, still is in the stowed position of key 1, all plays a part to keep.If stopper slot 26 side direction receive the side restriction that is parallel to glide direction, then need be pressed into its off-position to control button 17, so that make key 1 get into its stowed position from its extended position, vice versa.On the contrary; If people hope and can forward key 1 to stowed position from its extended position, and don't must be by control button 17, then stopper slot 26 be in stowed position one side the side (in other words; When at key 1 when its extended position changes its stowed position over to; The side that each protruding pin 25 is withstood) can tilt, so that the slip through on protruding pin 25, form a section and move and make control button 17 move into its off-positions.

Pack into the assembling of shell 2 of key 1, be the end of introducing covers 5 side recesses 3 through the lock core that has been equipped with key 17, and pivot 16, spring 18 and control button 17 pack into this groove 10 and realization.Introducing this section end 14 to protruding pin 24 is to realize with such method, promptly through making control button 17 with respect to shell 2 and lock core 7 rotations, so that protruding pin 24 is engaged in the end 13.1 of this section inlet 13 in advance.Direction of rotation turns to the direction of rotation of stowed position identical with lock core 7 from extended position: this rotation should surpass 180 °, so that apply twisting stress in advance for spring 18.Then, press control button 17, so that make control button 17 carry out the end portion 13.2 of this section inlet 13.The spring 18 (this distortion should be still 180 ° with respect to its relaxation state) of distortion makes protruding pin 24 get into this section end 14 slightly, and the spring of compression makes control button 17 shift to its stuck position.Control button 17 can be taken apart through accomplishing opposite operation.

Should be noted that in addition; Each ditch 12 all also comprises an additional sections 15, reaches external surface 9 through an end, and reaches this section end 14 through the other end; And reach the part of end 13.2, make this part 13.2 of end include only a side and be positioned at external surface 8 one sides.Should 15 additional of sections work to be convenient to molded lock core 7.When moulding lock core 7, this groove 10 is realized by means of two movably coaxial cores, the end contact of two cores.One of them core comprises that some protrude into outside slide plate, in order to form this end 13.1 parts, comprises the outside slide plate of protrusion in another core, in order to a part and this section end 14 that forms end 13.2.Additional sections 15 allows the slide plate of the part of this section of formation end 14 and this end 13.2 to pass through.
