Description
Technical field
The present invention relates to a kind of new automobile active headrest.
Background technology
With expanding economy, automobile is increasingly becoming the main means of transport of modern humans society, and automobile gives our life
Work brings facility, but also brings greatly challenge to traffic simultaneously.Statistics according to Ministry of Communications shows, traffic accident
Incidence cumulative year after year, wherein rear-end collision account for significant proportion.And in all kinds of damages caused by rear-end impact, more there is 90% category
In neck whiplash injury, although belong to and slightly hinder rank, mortal injury, but thus caused long-term neck pain are seldom caused to occupant
Bitterly, spirit and material pressure to a certain extent will necessarily be brought to patient and society, so the design requirement of automotive headrest,
In addition to meeting comfortableness, it is often more important that security.
The content of the invention
Present invention aim to address above mentioned problem, there is provided a kind of new automobile active headrest.
The purpose of the present invention is accomplished by the following way：
A kind of new automobile active headrest, including fixed mount, limited block, sliding block, electromagnet, back-moving spring, movable part of resting the head on
Point, roller, connecting rod and support bar；When normal vehicle operation, electromagnet is in power failure state, and headrest moving part is maintained at just
Beginning position；When control unit judges that rear-end impact occurs, and sending signal connects electromagnet, produces electromagnetic attraction to lift dynamic iron
Core, so as to push up sliding block, rests the head on by linkage horizontal development, and realizes that final position constrains by limited block；When chasing after
After caudal knot beam, powered off to electromagnet, headrest can manually return to initial position.
Further, also including control system, including artificial selection unit, signal gathering unit, processing unit, display is pre-
Alert unit and execution unit；Artificial selection unit provides road surface and weather conditions information in environment for system, by driving
Member thinks setting；Signal gathering unit includes from vehicle speed sensor and distance measuring sensor, the distance in the workshop of Real-time Collection two and
The respective speed of two cars；The display in real time of display prewarning unit from the current running information of car, when detect be potentially dangerous when, swash
Warning module living, reminds rear car driver to take collision avoidance measure；Execution unit selects solenoid actuated, is responsible for triggering active headrest
Device；Processing unit is responsible for putting together the information that artificial selection unit and information acquisition unit are obtained, and according to safety
Spacing algorithm calculates current safety spacing, is judged according to Safety Evaluation Index, is touched when judging that vehicle exists to knock into the back
When hitting danger, start prewarning unit, remind rear car driver take collision avoidance measure, when judge vehicle cannot collision free when, then
Activation execution unit, starts Active headrest device.
The beneficial effects of the invention are as follows：
Active headrest simple structure of the present invention, it is safe and reliable with respect to backrest independence, can effectively protect occupant's neck to keep away
Exempt from damage, can hand-reset, reuse, it is with low cost.
Brief description of the drawings
Fig. 1 is structural representation of the invention.
Fig. 2 control system schematic diagrames.
Specific embodiment
It is further described in detail presently in connection with accompanying drawing.
As shown in figure 1, a kind of new automobile active headrest, including fixed mount 1, limited block 2, sliding block 3, electromagnet 4, again
Position spring 5, rest the head on moving part 6, roller 7, connecting rod 8 and support bar 9；When normal vehicle operation, electromagnet 4 is in dead electricity shape
State, headrest moving part 6 is maintained at initial position；When rear-end impact generation connection electromagnet 4 is judged, electromagnetic attraction is produced to lift
Dynamic iron core, so as to push up sliding block 3, rests the head on, and realize final position about by limited block 2 by the horizontal development of 8 mechanisms of connecting rod
Beam；After end when knocking into the back, powered off to electromagnet 4, headrest can manually return to initial position.
As shown in Fig. 2 automobile active headrest of the present invention also includes control system, including artificial selection unit 21, signal is adopted
Collection unit 22, processing unit 23 shows prewarning unit 24 and execution unit 25；Artificial selection unit 21 provides driving ring for system
Road surface and weather conditions information in border, setting is thought by driver；Signal gathering unit 22 include from vehicle speed sensor and
Distance measuring sensor, the distance and the respective speed of two cars in the workshop of Real-time Collection two；Display prewarning unit 24 in real time from car work as by display
Preceding running information, when detect be potentially dangerous when, activate warning module, remind rear car driver take collision avoidance measure；Hold
Row unit 25 selects solenoid actuated, is responsible for triggering Active headrest device；Processing unit 23 is responsible for the He of artificial selection unit 21
The information that information acquisition unit 22 is obtained puts together, and calculates current safety spacing, foundation according to safe distance between vehicles algorithm
Safety Evaluation Index is judged, when judging that vehicle has rear-end impact danger, starts prewarning unit, prompting rear car
Driver takes collision avoidance measure, when judge vehicle cannot collision free when, then activate execution unit 25, start active headrest dress
Put, realize the protection to occupant's neck.
Schematical specific embodiment of the invention is the foregoing is only, the scope of the present invention is not limited to.It is any
Those skilled in the art, done equivalent variations and modification on the premise of design of the invention and principle is not departed from,
The scope of protection of the invention should be belonged to.
