Description
Technical Field
The invention relates to the field of automobile articles, in particular to an automobile headrest structure which is beneficial to eliminating neck and head fatigue in a long-time driving process.
Background
The importance of safe driving of the automobile is increasingly paid attention to by drivers, and a series of automobile articles favorable for ensuring safe driving appear, wherein the automobile safety headrest not only can relieve the fatigue of the driver, but also can play a certain safety protection role.
According to the statistics of relevant departments, the head and the neck of a driver are injured in about 26 percent of rear-end accidents. The reason is that when a rear-end collision happens, a human body falls backwards due to inertia, the pressure of vehicle acceleration or deceleration or huge impact force generated by collision is extruded on a fragile neck, so that the spine of a driver or a passenger is likely to be injured, neck injury is one of the most common injuries, even a serious person causes a nervous system to have a problem and paralysis, in fact, even if the vehicle speed is only 10km/h, the forces of vehicle acceleration and deceleration are extruded on the fragile neck of the passenger, and if the neck of the driver or the passenger in the vehicle is not protected by a headrest, the neck of the passenger in the vehicle is likely to be injured. In the rear-end collision accident under the same condition, the probability that the neck of a driver or a passenger who uses the automobile headrest incorrectly feels pain is reduced by 40% when the automobile headrest is used correctly, the neck damage probability of the driver or the passenger who uses the headrest with good use quality is reduced by 24% when the headrest with good use quality is used, obviously, the automobile headrest can play a role in buffering the traffic accident, the head of the driver is protected, and the huge instant impact force generated when the accident happens can be effectively buffered due to the existence of the automobile headrest, so that the fragile neck bone is protected, and the probability that the neck is damaged is reduced.
In the national standard, the automobile headrest belongs to one of the national automobile mandatory certification and detection items, and has strict regulations on material, strength, energy absorption, position, size and the like.

According to the automotive headrest structure implemented by the above technical solution of the present invention, it is apparent that the implemented front bracket 20, rear bracket 30, left side bracket 40, and right side bracket 50 constitute a parallelogram four-bar linkage mechanism composed of four planar bar linkage structures, that is: the left plane is the same as the plane connecting rod structure of the right plane, the front plane is the same as the plane connecting rod structure of the rear plane, and the left plane and the rear plane are different in shape, wherein the left side and the right side are set to be parallelogram mechanisms, the front side and the rear side are set to be rectangular mechanisms, the headrest adjusting mechanism accords with the motion principle of the parallelogram mechanisms, can do parallel motion and swing back and forth, and is convenient to adjust the headrest in the motion process.
As shown in fig. 5-6, in the automotive headrest structure implemented by the above technical solution of the present invention, when in use, a technician tilts the upper portion of the headrest portion 1 forward, and fixedly connects the lower portion of the headrest portion with the fixing holes for assembling the left side bracket 40 and the right side bracket 50, the head of the driver firstly contacts the upper portion of the headrest portion 1 backward and applies backward pressure to the upper portion of the headrest portion 1, so that the lower portion of the headrest portion 1 moves forward, that is, the left side bracket 4 and the right side bracket 50 drive the whole moving mechanism to move, and the lower portion of the headrest portion 1 also clings to the head of the driver, so that the head, especially the back brain, can be effectively buffered during the process from contacting the upper portion of the headrest portion 1 to moving the moving mechanism to enable the lower portion of the headrest portion 1 to cling to the head of the driver, and contusion or whiplash (i.e., bone or soft tissue injury caused by the acceleration and deceleration mechanism of the neck due to direct collision with the headrest portion or, of course, the displacement mechanism also facilitates a corresponding resetting after the head of the driver has left the head rest 1.
Further, in order to limit the moving mechanism and facilitate the resetting of the moving mechanism after the moving, a fixing lock 80 is connected in a through hole on the surface of the adjusting assembly 70, the fixing lock 80 has a fixing portion 81 at the lower end, and the fixing portion 81 is aligned with the saw tooth direction of the adjusting opening 71; the fixed lock 80 is fixed in the shaft hole of the main bracket 60 through the third rivet 82, one end of an unlocking spring 83 is connected in a small hole at the lower end of the fixed lock 80, and the other end of the unlocking spring 83 is fixed at the lowest U-shaped bending part of the main bracket 60, so that a technician can conveniently perform corresponding unlocking by means of external force on the basis of the moving mechanism.
As shown in fig. 5, the detailed operating state of the headrest structure for a vehicle according to the present invention is changed as follows:
at the beginning (at L)0State), the angle between the front bracket 20 and the fixed bracket 10 is about 80 degrees, the fixed part 81 is overlapped and locked with the lowest tooth of the adjusting opening 71, and the headrest is in a fixed state after being locked;
when the head moves backwards (at L)1State), the lock 80 moves upward, i.e., in the opposite direction, to start unlocking, by applying a backward pushing force to the headrest portion 1 and the unlocking spring 83;
the headrest portion 1 continues to be pushed, and the headrest continues to move (at L)2State), the fixing lock 80 continues to move upward until reaching the topmost part of the adjusting assembly 70, at which time the headrest cannot move any more, and rebounds after reaching a critical point;
when the headrest cannot move any more and rebounds after reaching the critical point, the fixing lock 80 moves until the fixing part 81 and the adjusting opening 71 are locked (at L)3State), the headrest can be fixed at the point if no longer stressed, and the whiplash injury of the head and neck can be prevented.
The automobile headrest structure implemented by the technical scheme of the invention is beneficial to promoting the contact between the back head of a passenger and the headrest, namely the contact between the back head and the surface of the headrest, and the back head can be stably supported by the contact between the headrest and the back head surface of the passenger, so that the fatigue can be eliminated in the long-time driving process under the condition of no inclination or protection.
