TECHNICAL FIELD
[0001] The utility model belongs to the technical field of automobile assembly, and relates to a swing arm structure facilitating rotation opening of a door. BACKGROUND
[0002] With the development of society, as a kind of traffic tool for travel, automobile is frequently applied in people's daily life. Due to the continuous development of automobile manufacturing industry, more and more new structures are applied on automobile for improving the competitiveness of automobile in market.
[0003] In the structure of automobile door, the traditional door is horizontally pushed open to the outside, and the door structure is difficult to open under the condition that the distance between two sides is small, so that the driver and the passenger get off the car with difficulty, and when the force of the door pushed to the outside is too large, the door will rotate a large angle to the outside, the passenger pushes the door open with great force without carefully observing the side condition of the car, and the door is easy to collide with other passing cars or electric vehicles, which is easy to cause safety hazard. SUMMARY
[0004] The utility model discloses a swing arm structure facilitating rotation opening of a door, and the technical problem to be solved by the utility model is how to make the door open under the condition that the horizontal rotation angle is small.
[0005] The utility model discloses a swing arm structure facilitating rotation opening of a door, and the technical problem to be solved by the utility model is how to make the door open under the condition that the horizontal rotation angle is small.
[0006] In the present scheme, the fixed part is fixedly installed on the car body, and the end of the swing arm hinged to the fixed block can rotate outward around the fixed block during the opening of the door. Since the connecting rod is arranged on the inner side of the swing arm, the connecting rod will also pull the first connecting part inward while rotating outward with the swing arm, so as to rotate the rotating shaft to the side provided with the connecting rod, and the second connecting part drives the rotating disc to rotate around the rotating shaft. Since the inside of the rotating disc is hinged to the second connecting part, the first gear on the outside is also meshed with the second gear, and the rotating disc will also rotate upward while rotating around the rotating shaft, so that the door is opened horizontally outward and also rotates upward synchronously, so that the door is opened more completely, and personnel can get on and off the vehicle more conveniently. In the above structure, the door is rotated outward and upward at the same time, so that the door only needs to be opened outward by a small angle to open the door, reducing the angle of the door opening outward, and the door can be opened under the condition that the distance between the two sides is small. The structure of the limiting block arranged on the swing arm will abut against the fixed block when the swing arm rotates outward by a certain angle, so that the swing arm cannot continue to open outward, and at this time the door will also rotate upward to the maximum angle, so that the driver and passenger can get in and out of the vehicle, avoiding the technical problem that the sliding door in the prior art will be opened greatly when the opening force is too large, and improving the safety of the vehicle.
[0007] In the above swing arm structure for facilitating the rotation of the door, a plurality of fixed plates radiating outward from the center are arranged on the rotating disc, and the door is fixedly connected to the fixed plates. The door is installed on the fixed plates, and the rotating disc drives the door to open and rotate through the fixed plates. The plurality of fixed plates can improve the strength of the connecting structure. A handle is installed on the door, and the door is pulled outward to rotate the swing arm, so that the door can be manually pulled open.
[0008] In the above swing arm structure for facilitating the rotation of the door, a connecting frame fixedly connected to the swing arm is arranged at the bottom of the rotating shaft, an electric telescopic rod is arranged on the connecting frame, one end of the electric telescopic rod is hingedly connected to the connecting frame, the other end is hingedly connected to the fixed block, and electric switches for controlling the extension and retraction of the electric telescopic rod are arranged inside and outside the door. The connecting frame is used to install the electric telescopic rod. When the electric switches are pressed, the electric telescopic rod is extended and pushes the connecting frame, so that the swing arm fixedly connected to the connecting frame rotates outward, thereby realizing the function of automatically opening and closing the door. When the electric telescopic rod is retracted, the swing arm is pulled inward, and the door rotates to close.
[0009] In the above swing arm structure for facilitating the rotation of the door, reinforcing ribs are arranged on both sides of the swing arm, and an avoiding groove is arranged on the reinforcing rib on which the connecting rod is installed. One section of the connecting rod is arranged in the avoiding groove. The reinforcing ribs are arranged obliquely on the swing arm to improve the strength of the swing arm structure, and the connecting rod is arranged in the avoiding groove to reduce the space occupied by the swing arm structure in the door, so that the door is thinner.
[0010] In the swing arm structure for facilitating the rotation opening of the vehicle door, the fixed block is provided with an extension protruding to one side of the swing arm, and the connecting rod is hinged to the extension on the swing arm.
[0011] In the swing arm structure for facilitating the rotation opening of the vehicle door, the swing arm is provided with a fixed buffer pad, and the buffer pad is arranged at the position of the swing arm in contact with the extension.
[0012] In the swing arm structure for facilitating the rotation opening of the vehicle door, a bearing is arranged between the second connecting part and the rotating disc, one end of the second connecting part is provided with a fixed end cover, and the end cover abuts against one side of the rotating disc away from the rotating shaft.
[0013] Compared with the prior art, the utility model has the following advantages:
[0014] 1. In the scheme, the vehicle door is rotated to open outward and upward, so that the vehicle door can be opened only by rotating a small angle outward, the opening angle of the vehicle door is reduced, and the vehicle door can be opened when the distance between the two sides is small.
[0015] 2. In the scheme, the limiting block is arranged on the swing arm, when the swing arm is rotated outward by a certain angle, the limiting block abuts against the fixed block, so that the swing arm cannot be continuously opened outward, at this time, the vehicle door is also rotated upward to the maximum angle, so that the driver and the passenger can get in and out of the vehicle, and the technical problem that the sliding door in the prior art is opened too much when the opening force is too large is avoided, and the safety of the vehicle is improved.
