Description
Technical Field
The invention relates to the technical field of automobile accessories, in particular to a submergence preventing restraint device for an automatic driving automobile seat.
Background
At present, the attention of people on the automatic driving automobile shifts from simple feasibility to comfort and safety, according to the investigation of the sitting preference of the automatic driving automobile, 77.6 percent of people prefer a face-to-face sitting mode, the most favored seat orientation is to rotate a seat which is traditionally arranged by 90-180 degrees, so the rotatable automobile seat is inevitably the mainstream of the automatic driving automobile seat in the future, and a pre-collision technology of an active seat rotation strategy is proposed in academic world aiming at the safety of a highly automatic driving automobile and a fully automatic driving automobile, namely when the automobile detects unavoidable collision, the seat rotates a certain angle within 200ms to reduce the damage of a passenger in the collision, but the restraint of a single triple safety belt is insufficient in the rotating process, the lower limb of the passenger violently rises due to the inertia effect, and the serious descending consequence of the passenger is caused, since the degree of injury of the passenger during the collision inevitably increases due to the dive, a restraint device for restraining the lower limbs of the passenger is required to effectively solve the problem of the dive of the passenger, thereby ensuring that the injury of the passenger is effectively reduced during the collision of the autonomous vehicle.
Disclosure of Invention
The invention aims to provide a submergence preventing restraint device for an automatic driving automobile seat, which can effectively solve the problem that the lower limbs of passengers lift up during the rotation of the seat through multiple times of simulation and test, further remarkably improve the submergence phenomenon of the passengers, help to reduce the damage to the passengers during collision and provide guarantee for the smooth realization of a pre-collision technology of an automatic driving automobile active seat rotation strategy.
In order to achieve the purpose, the invention adopts the following technical scheme: the utility model provides a prevent restraint device that dives for autopilot car seat, includes small-size motor, rotation axis, shank accommodate device, foot strutting arrangement, electric putter controlling means, electric putter member, the horizontal baffle of shank, its characterized in that: the small-sized motor is fixedly connected with the front lower end of a cushion of the automatic driving automobile seat, two ends of the seat are symmetrically and respectively provided with one small-sized motor, the rotating shaft is arranged between the two small-sized motors and can rotate along with the two motors in a controlled manner, the leg accommodating device is fixedly connected with the rotating shaft, the leg supporting device is provided with a strip-shaped groove, is arranged below the leg accommodating device and can be controlled to stretch out and draw back, the electric push rod control device is arranged in the leg supporting device and symmetrically and respectively arranged at two sides of the leg supporting device, the electric push rod piece and the electric push rod control device jointly form an electric push rod, the linear movement function can be realized, the leg transverse baffle plate is fixedly connected with the electric push rod piece and can slide from the upper surface of the leg accommodating device to the inside of the leg supporting device, and the leg transverse baffle plate is hidden in the strip-shaped groove of, when the seat rotates emergently, the leg transverse baffle is pushed into the groove on the upper surface of the leg accommodating device by the electric push rod piece.
Compared with the prior art, the invention has the following beneficial effects:
1. the device can effectively solve the problem that the lower limbs of passengers are raised in the rotation of the seat, thereby remarkably improving the phenomenon that the passengers dive and being beneficial to reducing the injury of the passengers in collision.
2. The angle that the device can adjust shank accommodate device through small-size motor to the travelling comfort of autopilot car seat has been promoted.
3. The device can adjust the height of the foot support device, thereby being suitable for passengers of various sizes.

Detailed Description
The invention will be further explained with reference to the accompanying drawings: as shown in fig. 1 to 4, a dive prevention restraint device for an automatic driving car seat comprises a small motor 1, a rotating shaft 2, a leg accommodating device 3, a foot supporting device 7, an electric push rod control device 6, an electric push rod piece 5 and a leg transverse baffle 4, and is characterized in that: the small-sized motor 1 is fixedly connected with the front lower end of a cushion of an automatic driving automobile seat, two ends of the cushion are symmetrically and respectively provided with one small-sized motor, the rotating shaft 2 is arranged between the two small-sized motors 1 and can rotate along with the two motors 1 in a controlled manner, the leg accommodating device 3 is fixedly connected with the rotating shaft 2, the leg supporting device 7 is provided with a strip-shaped groove, is arranged below the leg accommodating device 3 and can be controlled to stretch and retract, the electric push rod control device 6 is arranged in the leg supporting device 7 and is symmetrically and respectively provided with one leg accommodating device 7 in two sides, the electric push rod piece 5 and the electric push rod control device 6 jointly form an electric push rod, the linear movement function can be realized, the leg transverse baffle 4 is fixedly connected with the electric push rod piece 5 and can slide from the upper surface of the leg accommodating device 3 to the inside of the leg supporting device 7, when the seat does not rotate emergently, the leg transverse baffle 4 is hidden in the strip-shaped groove of the foot supporting device 7, and when the seat rotates emergently, the leg transverse baffle 4 is pushed to the groove on the upper surface of the leg accommodating device 3 by the electric push rod piece 5.
The working principle is as follows: after a passenger gets on the automobile, the legs are placed in the leg accommodating devices 3, the feet are placed on the foot supporting devices 7, then the angle of the leg accommodating devices 3 and the height of the foot supporting devices 7 are adjusted according to the size of the passenger, the design is carried out to ensure that the feet of the passenger cannot influence the moving-in and moving-out of the leg transverse baffle plates 4 from the foot supporting devices 7, when the automobile is driven automatically and normally, the leg transverse baffle plates 4 are hidden in the foot supporting devices 7, when unavoidable collision occurs, the seat rotates for a certain angle in a very short time, at the moment, the leg transverse baffle plates 4 extend out of the foot supporting devices 7 and move into the grooves in the leg accommodating devices 3, the function of inhibiting the lifting of the lower limbs is achieved, the phenomenon that the passenger dives in the rotating process of the seat is effectively prevented, and therefore the damage of the passenger is minimized in the collision.
The embodiment is only an illustration of the concept and implementation of the present invention, and is not a limitation, and technical solutions without substantial changes are still within the protection scope under the inventive concept.
