Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of door check, in particular to a mounting structure of door check, a door and a vehicle. BACKGROUND

[0002] The door check can set the maximum opening angle of the door, which is generally 65-70 degrees. The angle is determined according to the convenience of getting on and off the vehicle, the convenience of closing the door after getting on the vehicle, and the non-interference between the door and the vehicle body. In certain situations, such as when the vehicle is parked on a slope or encounters wind, the door check can ensure that the door remains open stably and will not automatically close.

[0003] At present, the inner panel of the door where the door check is installed is usually made of steel material. However, the steel material itself is relatively heavy. The use of aluminum alloy material has the characteristics of light weight and high strength, and becomes an ideal material for vehicle lightweighting, which can solve the problem of heavy weight of the inner panel of the door. However, the aluminum alloy has low elongation and poor formability. Due to the opening and closing force of the check, the inner panel of the door has a small draft angle, which causes the installation area of the check of the aluminum alloy inner panel of the door to be prone to cracking.

[0006] The inner panel of the door comprises a first surface and a fixed surface fixedly connected, and the first surface is inclinedly arranged towards the front of the door along the direction away from the fixed surface;

[0007] The mounting plate comprises a connecting surface and a mounting surface, the connecting surface is fixedly connected with the fixed surface, and the mounting surface is inclinedly arranged towards the front of the door along the direction away from the connecting surface;

[0008] The first surface and the mounting surface are both provided with mounting holes for mounting the check.

[0009] Optionally, the inclination angle of the first surface towards the front of the door ranges from 15 degrees to 20 degrees.

[0010] Optionally, the inclination angle of the mounting surface towards the front of the door ranges from 3 degrees to 6 degrees.

[0011] Optionally, a first bending part is arranged on the side of the mounting surface away from the connecting surface, and the first bending part is bent towards the front of the door.

[0012] Optionally, the mounting surface has a second bending part, the second bending part is fixedly connected with the first bending part, the second bending part is bent towards the rear of the door, and the first bending part is located between the second bending part and the connecting surface.

[0013] Optionally, the mounting plate is provided with a positioning hole for mounting the limit stopper.

[0014] Optionally, a plurality of welding points are arranged on the fixing surface and the connecting surface for welding.

[0015] Optionally, a plurality of riveting points are arranged on the fixing surface and the connecting surface for connection.

[0016] The application also provides a car door comprising the mounting structure of the limit stopper of the car door.

[0017] The application also provides a car comprising the car door.

[0018] As described above, the technical scheme of the application has at least the following beneficial effects: by inclining the first surface towards the front of the door, the inclination angle between the fixing surface and the first surface is increased, thereby increasing the forming angle of the aluminum alloy inner door panel, increasing the formability of the inner door panel, avoiding cracking of the inner door panel during forming, and by inclining the mounting surface towards the front of the door, the limit stopper is also inclined with the mounting surface, the angle of the side wall of the region of the mounting plate where the limit stopper is installed is increased, and the opening and closing force requirement of the limit stopper is met.

[0019] Through the above structure, the problem of cracking of the aluminum alloy inner door panel is solved, and the aluminum alloy door panel replaces the steel door panel, thereby reducing the weight of the whole vehicle body and achieving the effect of light weight.
