Description
Technical Field
The invention belongs to the technical field of vehicle accessories, and particularly relates to a vehicle rearview mirror.
Background
With the increase of social economy, private cars are in a large quantity; the vehicles running on the traffic road are more and more; since the rear-view mirrors are the outermost positions of the vehicle, the width of the two rear-view mirrors is also the largest; therefore, in the case of the annual automobile traffic accident, the rear view mirror collision, scratch, and drop occupy a large rate; the damage of the rearview mirror caused by collision, scratch, falling and the like brings property loss to the vehicle owner.
The existing automobile rearview mirror can be scratched only when in slight contact, and if the automobile rearview mirror is slightly heavier, the automobile rearview mirror is damaged by collision and even falls off; the property damage is still large; even if the rear-view mirror is hit by the vehicle body, passers-by running on the roadside, and the like, the safety of the person and great property loss are caused.
According to the vehicle rearview mirror, under the action of the collision trigger cover on the rearview mirror, when the rearview mirror of an automobile collides, the collision trigger cover drives the trigger device to rotate in the collision rotating support, so that the rearview mirror can rotate and move for a certain angle under the action of light collision force when the rearview mirror slightly collides; when the rearview mirror is seriously collided, the rearview mirror can rotate and move by a larger angle under the action of a very large collision force and generally stops at more than 90 degrees, because the rearview mirror of the opposite automobile can be separated from the rearview mirror of the automobile when reaching 90 degrees, the rearview mirror of the automobile generally rotates by more than 90 degrees under the actions of inertia, increased resistance and speed reduction of a sliding damping fixture block and a sliding damping cushion until the rearview mirror stops, and the larger the rotating angle is, the larger the collision force is, the larger the rotating angle is, the larger the increased resistance of the sliding damping fixture block and the sliding damping cushion is, and the secondary injury caused by the rotating ring of the rearview mirror is prevented; meanwhile, after collision occurs, the rearview mirror body is not greatly damaged, and the rearview mirror body can be hardly damaged or damaged to a minimum extent or even not damaged due to the fact that the anti-collision paste and the like are pasted to play a role in buffering; because the vehicle rearview mirror disclosed by the invention can be manually returned after the rearview mirror rotates after collision occurs, the conditions of part breakage and the like cannot be caused, and the abrasion of the rearview mirror is within normal use loss. Therefore, the invention has the functions of collision prevention and return, and is certainly limited to the function of collision prevention of rearview mirrors.
Disclosure of Invention
The invention aims to provide a vehicle rearview mirror, which solves the problems that the existing vehicle rearview mirror is not anti-collision, and is damaged by collision or even falls off when the vehicle rearview mirror is collided by the action of a collision trigger cover, and the collision trigger cover drives a trigger device to act when the vehicle rearview mirror is collided.
In order to solve the technical problems, the invention is realized by the following technical scheme:
the invention relates to a vehicle rearview mirror, which comprises a rearview mirror body, a rearview mirror support, a collision rotating support, a collision triggering cover and a triggering device, wherein the collision rotating support is arranged on the rearview mirror body;
the periphery side of the back of the rearview mirror body is provided with a notch matched with the collision trigger cover; the collision trigger cover is connected with the notch in a sliding manner in the front-back direction; an elastic part A is fixed on the back of the rearview mirror body; the elastic member a may be a spring; the other end of the elastic piece A is in contact with the inner surface of the collision trigger cover;
the trigger device comprises a collision trigger plate; an elastic part B is fixed on the surface of one side of the collision trigger plate, which is close to the reflector on the rearview mirror; the elastic member B may be a spring; the other end of the elastic part B is in contact with the inner surface of the rearview mirror body; a limiting sliding column is fixed on the other side surface of the collision trigger plate; the limiting sliding column penetrates through the shell of the rearview mirror body; a trigger post is fixed on the inner surface of the collision trigger cover;
the position relation of triggering post and spacing slip post has respectively:
when the automobile is static and the rearview mirror is not collided, a larger distance exists between the trigger column and the limiting sliding column; this greater distance is also typically between 3mm and 10 mm;
when the automobile runs at a high speed and the rearview mirror is not collided, a small distance exists between the trigger column and the limiting sliding column; the smaller distance is also typically between 2mm and 5mm, with the larger distance being greater than the smaller distance; the reason for changing the larger distance into the smaller distance is that the collision trigger cover can be subjected to air resistance when the automobile runs at a high speed, and the impact of the air resistance on the collision trigger cover enables the collision trigger cover to move backwards for a smaller distance; the setting of the distance can set the elastic coefficient k of the elastic part A according to the magnitude of the force received by the shape of the collision trigger cover during the actual driving process, and the elastic coefficient k is slightly larger;
when the automobile rearview mirror collides, the trigger column moves towards the rear direction of the automobile and moves to be in contact with the limiting sliding column, and the limiting sliding column is pushed towards the rear direction of the automobile by the trigger column;
it is also explained here why the above-mentioned small distance needs to be present, since the impact force is clearly much greater than the air resistance, compared to the air resistance; the smaller distance is at least the smaller distance between the trigger post and the limiting sliding post under the condition that the highest speed is allowed and the air resistance of the collision trigger cover is the largest, namely the trigger post is changed into contact from the existing distance only under the force of the collision force level, and the limiting sliding post is pushed towards the rear direction of the automobile for a small distance, about 1mm-5mm, and optimally controlled to be about 1-2 mm; the triggering can be realized by the minimum moving distance, because when the vehicle runs at high speed, the collision rotating support is triggered at the moment of collision, and the collision rotating support can rotate;
meanwhile, when the trigger column pushes and triggers the limiting sliding column towards the rear direction of the automobile, a small distance, which is about 1mm-5mm, is formed between one surface of the cover opening of the collision trigger cover and the inner surface of the opening of the rearview mirror body; after collision and triggering, when the automobile runs at high speed, if one surface of the cover opening of the collision triggering cover is in contact with the rearview mirror body, the rearview mirror can be damaged, and if the collision triggering cover cannot move continuously during triggering, the collision force applied to the collision triggering cover can be instantly increased to a level that the rearview mirror is broken; if a tiny gap or a tiny distance exists between one surface of the cover opening of the collision trigger cover and the rearview mirror body, the collision trigger cover can continue to move, the collision force applied to the collision trigger cover cannot be obviously increased until the collision rotary support rotates, and the collision force applied to the collision trigger cover cannot be obviously increased; during the period, although the force is slightly increased, the increased force does not cause substantial damage to the rearview mirror; in the process, the time in the process from triggering to colliding with the rotary support for rotation is extremely short or very little, at least the time can be screened by a technical means, namely the tightness, the toughness and the like of the trigger rope are required to be screened, the tightness of the trigger rope is required to be maintained in a high state, the material of the trigger rope is selected to be capable of triggering the trigger rope as quickly as possible instantly, and the characteristics of extremely low elasticity, high strength and the like are realized; in the actual manufacturing process, the aspects of smoothness, sensitivity and the like of product parts need to be considered; in the component, in order to better enable the trigger block to move, the positions of the edge and the like of the component can be processed by conventional means such as forming a round angle and the like; so as to meet the triggering requirement of collision as much as possible;
when the limiting sliding column is pushed, the collision trigger plate can drive the trigger rope to move by standing the horse, the trigger rope can drive the trigger block to move upwards by standing the horse by moving the trigger rope, and once the trigger block moves upwards, the trigger block can slide into the circular sliding groove from the upper part of the limiting hole B; the collision rotating support can rotate; the height difference between the inner bottom surface of the circular sliding chute and the corresponding structural feature in the limiting hole B can be extremely small, even 0.01mm, and the adjustment is carried out according to the required sensitivity, and the optimal height difference is generally within 0.5mm-2 mm;
