Description

Car belt automatic tieing and untieing device

Technical field

The utility model relates to a kind of car belt automatic tieing and untieing device; It is the isolated plant that is used for fastening automatically the safety strap of conciliating drive a car last front-seat chaufeur and occupant.

Background technology

At present, nearly all automobile comprises that front-seat chaufeur of automobiles such as car, utility van, rolling cart and passenger vehicle and occupant all dispose safety strap.The effect of its safety strap is when automobile because unforeseen circumstances and emergency braking and when bumping, and safety strap can hold onto driver and crew's health in the moment tensioning, avoids colliding, to reach protection driver and crew purpose of safety.Safety strap major part on the existing automobile is the pre-tensioning safety strap of bikini.It is made up of ribbon, the device of crispaturaing, dead bolt, snap close and attachment point etc., its method of fastening be driver and crew with hand pull ribbon, another holds dead bolt, walks around the health of oneself, inserts snap close, whole process needs two hands to be used alternatingly, and is very inconvenient.Simultaneously,, do not want to take the trouble, cause safety strap to become unnecessary device owing to after most of people get on the bus, do not want to fasten the safety belt.And when traffic accident takes place, the driver and crew's that may work the mischief life security.Chinese patent 01235162.8 discloses a kind of automatic tieing and untieing device, though this device can be realized the safety strap automatic tieing and untieing, the track design complexity increases the device of crispaturaing, the cost height.

Summary of the invention

The purpose of this utility model is to overcome above-mentioned defective, and a kind of car belt automatic tieing and untieing device is provided.

The technical solution of the utility model: comprising that safety strap transports to carve with return mechanism, track, dead bolt and extension pin closes and separation device.It is to comprise ribbon, extension pin, dead bolt, motor and track that safety strap transports with return mechanism; Its dead bolt is to be through on the ribbon, and an end of dead bolt is provided with cylinder, hangs pin-and-hole, and hanging the pin inner end is to link to each other with steel cable, and outer end and dead bolt are carved and closed; Steel cable is to place in the track, its two ends with transport motor, returning electrical motor links to each other respectively; Track design is a geometric configuration fluting, is laid in ribbon lower end attachment point, extends safety belt lock catch along car inner bottom surface seat limit to instrument desk, at one section of the front instrument desk for the downward structure of fluting, so do not affect the appearance, for invisible structure designs; Dead bolt and hang pin and carve and close and separation device is to comprise hanging pin, dead bolt, spring, the outer hoodle of track; Dead bolt comprises cylinder, hangs pin-and-hole, and dead bolt is carved and closed by hanging pin-and-hole with hanging pin, is carved by spring, the outer hoodle of track and closes and separate.

Automobile starting or when reaching certain speed transmits signal by sensor, and motor rotates steel cable, hangs pin and tangles dead bolt, crosses driver and crew's health and snap close and carves and close along with the steel cable orbit about, reaches the purpose that fastens one's safety belt automatically.After stopping, driver and crew one press snap close, and dead bolt ejects automatically, returning electrical motor work, and dead bolt and extension pin are along with steel cable is got back to starting point along track, and also just along with dead bolt is got back to original start position, unnecessary ribbon is withdrawn in the ribbon groove ribbon.

This device is under the situation that does not influence driver's operation, can help driver and crew to fasten one's safety belt automatically, overcome driver and crew the conventional security band is not thought the idea that is or do not want to take the trouble, for driver and crew's life security provides guarantee, it is a kind of desirable car belt automatic tieing and untieing device.

Below in conjunction with accompanying drawing the utility model is described in detail.

The specific embodiment

Embodiment one

Referring to above-mentioned accompanying drawing, car belt automatic tieing and untieing device is to comprise that safety strap transports with return mechanism, track 6, hangs pin 2, dead bolt 3, dead bolt and extension pin and carve and close and separation device.It is to comprise ribbon 1, hang pin 2, dead bolt 3, transport motor 8, returning electrical motor 4, steel cable 5, track 6 and snap close 7 that safety strap transports with return mechanism, dead bolt 3 slidably, its ribbon 1 is to pass dead bolt 3 can freely pull.The inner end that hangs pin 2 is connected with steel cable 5 in track 6, and outer end and dead bolt 3 are carved and closed.Track 6 can be designed to various geometric configuratioies, as circular, square, and slots thereon.Steel cable 5 two ends connect returning electrical motor 4 and transport motor 8, and middle steel cable 5 is to place in the track 6 in order to hang pin 2, and steel cable 5 is than the groove width big (slightly) of track 6.Track 6 starting point ends are the following attachment point of ribbon 1, middle through the bottom surface to instrument desk, the terminal snap close 7 that connects, built-in steel cable 5 and hang pin 2, track 6 are during to the instrument desk surface, fluting downwards.Hang pin 2 and be provided with inside and outside

hoodle

11,10, interior hoodle 11 contact with track, and spring 9, outer hoodle 10 are connected with dead bolt 3, and dead bolt 3 and ribbon 1 junction also are provided with cylinder 12, a snap close and carve and close hole and extension and sell to carve and close the hole.Dead bolt and hang pin and carve and close and separation device is formed by hanging pin 2, dead bolt 3, spring 9, the outer hoodle 10 of track.Dead bolt 3 places to be hung on the pin 2, is carved by spring 9, the outer hoodle 10 of track and closes and separate.

The utility model principle of work: automobile starting or when reaching certain speed, transmit signal by the sensor on the change speed gear box, or press switch, transporting motor 8 starts working, because ribbon 1 and dead bolt 3 are to connect together, dead bolt 3 and extension pin 2 are carved and are closed, hanging pin 2 is connected with steel cable 5, steel cable 5 with returning electrical motor 4, transport motor 8 and be connected, therefore, ribbon 1 is along with dead bolt 3 sells 2 owing to the rotation of transporting motor 8 together with hanging, along with steel cable 5 moves and pulled, moves, to snap close 7 places, dead bolt 3 is just carved with snap close 7 and is closed through track 6.Carve close after, ribbon 1 ties up on one's body the driver and crew automatically, unnecessary length reclaims in the device of crispaturaing.It is fashionable that dead bolt 3 and snap close 7 are carved, and by switch, transports motor 8 and quit work, and finishes the frenulum process.When ungirding, only need flicking snap close 7 buttons, dead bolt 3 just ejects snap close 7, by on-off signal, returning electrical motor 4 is started working, and dead bolt 3, extension pin 2 move by steel cable 5, get back to the starting point place of ribbon 1, also just along with dead bolt 3 is got back to the starting point place, unnecessary ribbon can be recovered in the device of crispaturaing ribbon 1, finishes the process of the ribbon 1 of unfastening one's seat-belt.

The belting of separating of the present utility model has also designed a manual unit.When pressing snap close 7, dead bolt 3 is ejected, and ifs circuit breaks down, and then separates with extension pin 2 to ribbon 1 direction by holding dead bolt 3, reaches release, ungirds, and finishes ribbon 1 process of untiing.

The utility model also is provided with manually fastens key, presses this key, machine operation, and automatic frenulum, not according to this key, this device is not worked, and when having arrived certain speed, then starts working.The about 5-7 of process second that this device is fastened and ungirded has solved driver and crew the conventional security band has not been thought the problem that is or do not want to take the trouble, has ensured driver and crew's life security.
