Description

The automobile burglar seat

The utility model relates to alarms and security systems for automobiles, a kind of specifically automobile burglar seat.

At present, automobile is of a great variety with anti-theft product, is broadly divided into machinery, electronics two series products.Mechanical anti-theft product such as anti-theft column lock, its principle can be summed up as fixedly becomes a connector with in bearing circle and the power-transfer clutch below it, throttle, the foot brake any one with lockset, bearing circle can not be rotated, power-transfer clutch, throttle or foot brake can not move, and the people can't drive and then theft-proof purpose to reach, but because lockset is exposed to space outerpace, easily destroyed, use also trouble, especially when frequent stop and start car, time-consuming, effort.

The electrical type anti-theft product mostly is vibration alarming, the central controlled lock remote firing, and the theft-proof electron system of several functional unifications such as squelch anti-stealing when the illegal motor-car of people, causes body vibrations, makes warning circuit work send police whistle sound.But its sensitivity is difficult for adjusting, cross the effect that do not have when hanging down, when sensitivity is too high, rain heavily, hand bumps even ground-surface vibration all can cause the whistling your writing, and child plays skin and pats the normal misunderstanding of making a noise, also easily done mischief by the people, when system was in the squelch anti-stealing function, the body vibrations system sent radio signal, and the radio signal receiver that the people carries sends annunciator.But above-mentioned shortcoming is arranged too, and receptor is effective in 150 meters scopes, limited people's action, also easily malfunctioning by other signal interference, when remote firing, code signal can be caused automobile stolen by intercepting and capturing, consume electric power when its distinct disadvantage also is system works, make after the installation that automobile circuit is complicated, the probability height of et out of order, and behind the et out of order, be difficult for judging and repair.Whole warning costs an arm and a leg, and has limited its use.

The purpose of this utility model is to overcome above-mentioned shortcoming, and a kind of automobile burglar seat is provided, and anti-theft capability is strong, and is simple in structure, easy to use, and theftproof hidden is strong, is difficult for destroyedly, and cost is low.

The purpose of this utility model is achieved in that

A kind of automobile burglar seat, form by seat that can lean forward and blocking device, junction at the chair back and the seat support of driver chair of automobile, in captive joint one rotating shaft of chair back lower end, this rotating shaft is stretched out by the chair back one side, its side goes out on the end worm gear is housed, the worm shaft of this worm gear of transmission and a tapered end lock core be connected this worm shaft connection actuating device.

The purpose of this utility model can also realize by following measure:

Described worm shaft bonded assembly actuating device can be micromotor---reductor.

The actuating device of described transmission worm shaft can be bevel-gear sett, and its driven wheel of differential is installed in worm shaft, and the drive bevel gear that is engaged with is installed on casing, and this drive bevel gear is by handle drives.

In one embodiment, the coaxial lonely groove toothed wheel that is equipped with of the driving gear of described transmission worm-wheel shaft, be set with an annular cover on this orphan's groove toothed wheel external diameter, this annular cover is connected with the one handle sleeve pipe, the bottom of this sleeve pipe is equipped with a steel ball and is crouched into the lonely groove of lonely groove toothed wheel, in the sleeve pipe of steel ball top depression bar is housed, the platen with finger control is equipped with in the end that this depression bar stretches out from the sleeve pipe top.

In another embodiment, the coaxial rectangular teeth ratchet that is equipped with of the driving gear of described transmission worm-wheel shaft, this ratchet is by making two-way drive by oppositely directed ratchet, and this ratchet is connected in operating handle.

The utility model has following useful effect:

Utilize the adjustability of driver seat backrest, the chair back is regulated forward after bearing circle is covered, with chair back locking, this moment, the chair back played three kinds of effects.

One: operator's saddle can't be sat the people to drive a car.

Its two: by the particular design to chair back head, bearing circle can be fixed, automobile is in stays.

Its three: bearing circle and dish below throttle, power-transfer clutch etc. are sheltered the people can't be driven.

Comprehensive above-mentioned three kinds of effects have reached theft-proof purpose.

This automobile burglar seat has following characteristics:

1, regulates lock and possessed locking and two kinds of functions of chair back adjusting angle simultaneously, the convenience that operates, flexible.Because worm gear, worm drive have self-locking performance, in a single day the chair back mixes up angle, even do not pull up key.It can not move yet again, does not resemble need screw the existing seat again, and is particularly convenient under steam.

2, theftproof performance improves, the chair back has also been covered the mechanism of below after covering bearing circle and locking, not having can be for the space of driving, regulating lock settles in the left side, seat, be subjected to the shielding of the top chair back and left side door case, be difficult for by artificial destruction, the people can only externally set about with back seat, expose not have and send, do not resemble existing Car Burglar Alarm, the perpetrator can be sitting in and do destruction in the compartment, and disguised strong, the difficult drawback of being discovered by the people is arranged.

3, the annex after existing antitheft equipment mostly is vehicle and dispatches from the factory after portably using inconvenience, adopting this device, only improves seat design getting final product.

4, at armchair structure design, the selection of material and install and note to improve intensity, can improve its theft-proof reliability greatly, if with existing machinery, the electrical type anti-theft product is used, and the robber is hung back, and protects car owner's automobile.

Now in conjunction with the accompanying drawings with preferred embodiment 1:

Fig. 1 is the profile scheme drawing that the utility model chair back leans forward and covers bearing circle.
