Background

For the protection type vehicle, need will keep the door open state when using under some special conditions, and the door dead weight of protection type vehicle is generally heavier, and door stop device of ordinary structure can't ensure that the door keeps open state, influences personnel's operation, or appears the door and closes suddenly, causes the injury to the personnel.

SUMMARY OF THE PATENT FOR INVENTION

In view of the above problems, the present invention is directed to a door closing force applying mechanism for a protective vehicle and a vehicle door assembly including the same, so as to apply a force to a vehicle door when the vehicle door is opened to a specific position, and prevent the vehicle door from closing by itself under a specific working condition to cause injury to people. The purpose of the invention is realized by the following technical scheme:

the invention firstly provides a protective type vehicle door closing force applying mechanism, which comprises a limiting clamp arranged on a vehicle door and a limiting bent plate arranged on a vehicle body connected with the vehicle door:

the limiting clamp is provided with a fixed end and a free end, the limiting clamp is fixedly connected with the car door through the fixed end, and a space is reserved between the free end of the limiting clamp and the car door;

the limiting bent plate is provided with a fixing part and an arc arch part, the limiting bent plate is fixedly connected with the vehicle body through the fixing part, the distance between the end part of the arc arch part and the vehicle body is smaller than the distance between the arc arch peak part and the vehicle body, and the end part of the arc arch part is a hard elastomer;

when the vehicle door is opened, the limiting clip rotates along with the vehicle door to enable the free end of the limiting clip to extend into the arc arch part of the limiting bent plate and finally be fixed between the arc arch part and the vehicle body.

Furthermore, the limiting bent plate is of an integrally formed structure and is made of spring steel.

Furthermore, the free end of the limiting clamp is provided with a turnover roller, and the roller can rotate around the axis of the end part.

Furthermore, the limiting clamp is a rectangular ring body formed by connecting a plurality of columns end to end, an included angle between the ring surface of the rectangular ring body and the vehicle door is an acute angle, and a roller rotating around the axis of the roller is sleeved on the free end of the rectangular ring body; the inner diameter of the arc arch part of the limiting bent plate is not less than the outer diameter of the roller; when the vehicle door is opened, the roller moves to the inner part of the arc arch part of the limiting bent plate along with the rotation of the vehicle door.

The invention further provides a vehicle door assembly which comprises the protective vehicle door closing force applying mechanism.

Further, connect through last hinge mechanism and lower hinge mechanism between door and the automobile body, the hinge mechanism contains the first articulated slab that is fixed in on the automobile body and is fixed in the second articulated slab on the door down, the fixed part of spacing bent slab is fixed to on the first articulated slab, the stiff end of spacing checkpost is fixed on the second articulated slab.

Furthermore, a groove is formed in the first hinged plate, the width of the groove is larger than the axial width of the arc arch part of the limiting bent plate, the arc arch part is suspended in the depth direction of the groove, and the limiting clamp rotates into the groove and moves into the arc arch part of the limiting bent plate when the vehicle door is opened.

Furthermore, a boss is arranged on the first hinged plate, a groove is formed in the boss, one end, far away from a hinged axis, of the groove penetrates through to a first side face of the boss, a fixing portion of the limiting bent plate is parallel to the arch crest tangent plane direction of the arc arch portion, the fixing portion is connected with the arc arch portion through an L-shaped connecting portion, a first portion of the L-shaped connecting portion extends along the first side face of the boss and is connected with the fixing portion, and a second portion of the L-shaped connecting portion extends along the bottom face of the groove in a square mode and is connected with the arc arch portion.

Further, the free end of the limiting clamp adopts a columnar rod, a roller capable of rotating around the axis of the columnar rod is sleeved on the columnar rod, the width of the columnar rod is smaller than that of the groove, and when the vehicle door is opened, the columnar rod rotates to the groove along with the vehicle door and moves into the arc arch part of the limiting bent plate.

Furthermore, a reinforcing support body is arranged between the limiting clamp and the second hinged plate.

The protective vehicle door closing force applying mechanism has the function principle that when the vehicle door is opened to a certain position, such as the maximum position, a force is applied to the vehicle door, and the vehicle door is prevented from being closed automatically under a certain specific working condition to cause injury to people.
