Abstract
The invention is concerned with back-off assurance equipment of driver seat when the crushing of vehicle happened. Set shoving power accepting rack inside of the front of vehicle and there are moving gear, locking tooth and unlocking tooth under the driver seat connecting with the ground of carriage and joggle with each other. The top of connecting pole fixes with shoving power accepting rack, the end of connecting pole is unlocking slanting block near the unlocking slant at the middle and low part of hand lever. The unlocking tooth of the end of hand lever contacts with the back surface of locking tooth of unlocking lever. The locking tooth matches with the moving gear and the top of unlocking lever connects with unlocking spring. When the crushing happens or the hand lever draws back, the unlocking tooth breaks away with the unlocking lever and the locking tooth breaks away the moving gear to move the driver seat. When the vehicle gets great crush from front vehicles and the top of carriage takes distortion and is locked, the driver seat can retreat with the force of crush to increase the safety space, avoid additional damage and increase the likelihood to save oneself and outside force succor.
Description
Technical field
The invention belongs to the fuse apparatus for vehicle technical field, relate to a kind of vehicle and clashed into driver's seat and can retreat, avoid the driver to be deformed the compartment and block, increase driver's safety distance safety device.
Background technology
Existing power actuated vehicle head device has bumper/spoiler, driver's seat is furnished with safety belt, but these only play safety effect to common bump or sudden stop, and when great car accident took place, often headstock was out of shape backward, even the driver hit injured after, the interior akinesia of operator's compartment that also is stuck in distortion is saved oneself, and leaves dangerous position, suffers unnecessary injury, can not in time obtain external force rescue, can only employ special rescue tool sawed-off, carry away the driver again after taking the parts that block the driver apart.So not only waste time and energy, influence traffic, even may jeopardize driver's life security.
Summary of the invention
The purpose of invention is the shortcoming that overcomes prior art, provide a kind of vehicle to be clashed into after, driver's seat can retreat, increase driver's safety distance, avoid the driver to be subjected to the safety device of inflicting heavy losses on more.
The technical scheme that adopts is in order to achieve the above object: vehicle is clashed into the back driver's seat and is retreated safety device, it is characterized in that being equipped with the power of hitting in the anterior inboard of vehicle accepts frame, the driver's seat below is equipped with ground, compartment and links to each other and intermeshing traveling gear, locking tooth and release tooth, connecting rod front end and the power of hitting are accepted frame and are fixedly linked, connecting rod end is that release tiltedly blocks, release inclined-plane near the hand lever middle and lower part, the release tooth of hand lever lower end contacts with the back side of release lever lower end locking tooth, the flute profile engagement of the flute profile of locking tooth and traveling gear, the upper end of release lever is connected with the release spring, be impacted or during the hand lever pull-up, the release tooth separates with release lever, the locking tooth separates with the traveling gear flute profile, and traveling gear can be movable on the stripe shape tooth, and the pulley of described driver's seat bottom can slide in the grooved track.
Advantage of the present invention is: the cab-over-engine truck of non-F/F, utility van, motorcoach, just in case be subjected to the huge bump in the place ahead, and make the compartment jeopardize driver's safety to internal strain, under the impact impetus, driver's seat can retreat, enlarged driver's safety distance, avoided the driver to suffer more injuries, the external force that may and help that has increased safety self-saving is in time rescued.
Description of drawings
Below in conjunction with drawings and Examples, the invention will be further described.
Fig. 1 structural representation of the present invention.
Among the figure, the 1-power of hitting is accepted frame; The 2-connecting rod; The 3-release tiltedly blocks; The 4-hand lever; 5-release inclined-plane; 6-release tooth; 7-locks tooth; The 8-release lever; 9-release spring; The extension spring of 10-hand lever; The 11-traveling gear; The 12-pulley; 13-stripe shape tooth; The 14-driver's seat; 15-grooved track;
The specific embodiment
Vehicle is clashed into driver's seat and is retreated safety device, it is characterized in that the front part of vehicle inboard is equipped with the power of hitting and accepts frame 1, the below of driver's seat 14 is equipped with and is fixed on the ground-surface grooved track 15 in compartment and links to each other, and with the stripe shape tooth 13 intermeshing traveling gears 11 on grooved track 15 tops, locking tooth 7 and release tooth 6, connecting rod 2 front ends and the power of hitting are accepted frame 1 and are fixedly linked, connecting rod 2 ends are tiltedly cards 3 of release, release inclined-plane 5 near hand lever 4 middle and lower parts, the release tooth 6 of hand lever 4 lower ends contacts with the back side of release lever 8 lower ends locking tooth 7, locking tooth 7 meshes with the flute profile of traveling gear 11, the upper end of release lever 8 is connected with release spring 9, hand lever 4 is held the location by hand lever extension spring 10 under the normal circumstances, can make release tooth 6 block locking tooth 7, locking tooth 7 and traveling gear 11 fixed engagement, traveling gear 11 again with stripe shape tooth 13 fixed engagement, so driver's seat 14 can not move.Be impacted or during hand lever 4 pull-ups, the lower part of release tooth 6 and described release lever 8 from, release lever 8 is subjected to 9 pullings of release spring, locking tooth 7 is separated with the flute profile of traveling gear 11, traveling gear 11 is owing to the effect of thrust or impact can be moved flexibly, the pulley 12 of described driver's seat 14 bottoms is done in the same way with traveling gear 11 and is synchronized with the movement, and slides in being fixed on the ground-surface grooved track 15 in compartment.The described power of hitting is accepted frame 1 and is framed structure.
