At present, the door hinge is usually a single-axis hinge, and the door is opened by rotating around the axis of the single-axis hinge. However, in the above method, the side space occupied by the door when it is fully opened is large. In a narrow parking space or when the adjacent car is parked too close, the door cannot be fully opened, and sufficient space cannot be provided for passengers to get on and off the vehicle, which is inconvenient for passengers to get on and off the vehicle. In order to solve the above problems, the embodiment of the utility model provides a door hinge and a vehicle.

[0028] First, refer to Figures 1 to 3 The embodiment of the utility model discloses a vehicle door hinge 1, comprising a vehicle body mounting member 103, a vehicle door mounting member 104 and a connecting rod assembly, wherein the two ends of the connecting rod assembly are rotatably connected to the vehicle body mounting member 103 and the vehicle door mounting member 104 respectively, and the connecting rod assembly, the vehicle body mounting member 103 and the vehicle door mounting member 104 form a four-link structure; the vehicle door mounting member 104 is used to be connected to the vehicle door 2, and the vehicle body mounting member 103 is used to be connected to the vehicle body 3, and the vehicle door 2 slides sideways between the open position and the closed position; the vehicle door hinge 1 also includes a limiting structure, and the limiting structure includes a first buffer limiting block 105, and the first buffer limiting block 105 is arranged on the vehicle door mounting member 104, and the connecting rod assembly includes a first connecting rod 101, and when the vehicle door 2 is in the closed position, the first connecting rod 101 is tightly pressed against the first buffer limiting block 105.

[0029] Specifically, the door hinge 1 is applied to a vehicle, and the vehicle includes a door 2 and a vehicle body 3. The door 2 is connected to the vehicle body 3 through the door hinge 1 to realize the opening and closing of the door 2. The shape of the four-bar structure can be a parallelogram. The connecting rod assembly includes a first connecting rod 101 and a second connecting rod 102. The two ends of the first connecting rod 101 are rotatably connected to the vehicle body mounting member 103 and the vehicle door mounting member 104 through a third rotating shaft 111 and a fourth rotating shaft 112, respectively. The two ends of the second connecting rod 102 are rotatably connected to the vehicle body mounting member 103 and the vehicle door mounting member 104 through a third rotating shaft 111 and a fourth rotating shaft 112, respectively. The vehicle body mounting member 103 and the vehicle door mounting member 104 are both integrated structures, which are easy to disassemble and assemble, and can reduce the design cost and mold opening cost of the parts.

[0030] The cross-sectional shape of the vehicle body mounting part 103 and the cross-sectional shape of the door mounting part 104 can be set according to actual needs, such as the cross-sectional shape of the vehicle body mounting part 103 and the cross-sectional shape of the door mounting part 104 can both be U-shaped. Two third rotating shafts 111 are arranged on the vehicle body mounting part 103. The third rotating shaft 111 may include a third shaft pin and a third shaft sleeve sleeved on the third shaft pin, and the third shaft sleeve is rotatably connected to the third shaft pin. The vehicle body mounting part 103 includes two side walls arranged opposite to each other, and the two ends of the third shaft pin are respectively connected to the two side walls. The third shaft sleeve in one of the third rotating shafts 111 is connected to the first connecting rod 101, and the third shaft sleeve in the other third rotating shaft 111 is connected to the second connecting rod 102.

[0031] The door mounting member 104 includes two folding plates 1041 arranged opposite to each other. Two fourth rotating shafts 112 are arranged on the door mounting member 104. The fourth rotating shaft 112 may include a fourth shaft pin and a fourth shaft sleeve sleeved on the fourth shaft pin, and the fourth shaft sleeve is rotatably connected to the fourth shaft pin. Both ends of the fourth shaft pin are respectively connected to the two folding plates 1041. The fourth shaft sleeve in one of the fourth rotating shafts 112 is connected to the first connecting rod 101, and the fourth shaft sleeve in the other fourth rotating shaft 112 is connected to the second connecting rod 102.

[0032] The door mounting part 104 is used to connect with the door 2, and the body mounting part 103 is used to connect with the body 3. The door mounting part 104 and the door 2 can be connected by screw connection, welding, etc. The body mounting part 103 and the body 3 can be connected by screw connection, welding, etc. An entrance and exit are opened on the body 3. When the door 2 is in the closed position, the door 2 completely blocks the entrance and exit. When the door 2 is in the open position, the door 2 is located on one side of the entrance and exit along the length direction of the body 3, and at this time, the entrance and exit are completely exposed. The side sliding of the door 2 specifically refers to the sliding of the door 2 along the length direction of the body 3.

[0033] The door mounting member 104 further includes a main body plate connected to two folding plates 1041. The first buffer stopper 105 is specifically arranged on the main body plate and located between the two folding plates 1041. The material of the first buffer stopper 105 can be rubber. Figure 1 When the door 2 is in the closed position, the door hinge 1 is in Figure 2 When the door 2 is in the closed position, the first connecting rod 101 is pressed against the first buffer stopper 105, which is used to limit the minimum opening of the first connecting rod 101 to prevent the door from passing through. At the same time, the first buffer stopper 105 also plays a role in buffering and shock absorption.

[0034] In the embodiment of the utility model, the first buffer stopper 105 is used to achieve the limit when the door 2 is closed, and the first buffer stopper 105 is integrated on the door hinge 1. When installing, only the door hinge 1 needs to be installed, and there is no need to install the limit structure separately, which saves the space occupied by the existing limiter and shortens the assembly time of the door hinge 1 and the limit structure. In addition, by setting the first buffer stopper 105, the door 2 can be prevented from passing through the customs. At the same time, when the door 2 is closed, the first buffer stopper 105 also plays a role of buffering and shock absorption to reduce the shaking of the door 2 when it is closed. In addition, the connecting rod assembly, the body mounting part 103 and the door mounting part 104 form a four-bar structure. After the door 2 is connected to the body 3 through the door hinge 1 including the four-bar structure, the door 2 can slide sideways between the open position and the closed position. When the door 2 slides sideways between the open position and the closed position, the side space occupied is smaller. Even in a narrow parking space or when the adjacent car is parked too close, the door 2 can be fully opened, thereby providing sufficient space for passengers to get on and off the vehicle, making it convenient for passengers to get on and off the vehicle.

[0035] The sliding door in the prior art needs to be limited by a sliding rail, and the sliding rail is arranged on the exterior surface of the vehicle body, which has a complex structure and affects the aesthetics. In the embodiment of the utility model, the side sliding of the door 2 can be achieved without the need for a sliding rail, which has a simple structure and does not affect the aesthetics.

[0036] Reference Figure 1 The limiting structure also includes a second buffer limiting block 106, which is arranged on the vehicle body mounting member 103. The connecting rod assembly also includes a second connecting rod 102. When the vehicle door 2 is in the open position, the side of the second connecting rod 102 away from the first connecting rod 101 is tightly pressed against the second buffer limiting block 106.

[0037] Specifically, when the door 2 is in the open position, the side of the second connecting rod 102 away from the first connecting rod 101 is pressed against the second buffer stopper 106, and the second buffer stopper 106 is used to limit the maximum opening of the second connecting rod 102, prevent the second connecting rod 102 from continuing to rotate, and prevent the door from being over-opened. In addition, when the door 2 is opened, the second buffer stopper 106 also plays a role of buffering and shock absorption to reduce the shaking of the door 2 when it is opened. In addition, the second buffer stopper 106 is arranged on the vehicle body mounting member 103. Compared with the second buffer stopper 106 being arranged on the second connecting rod 102, it can avoid the problems of weakening the structure of the second connecting rod 102, poor sealing, water and dust ingress, etc. caused by opening a hole on the second connecting rod 102.

[0038] Reference Figure 1The limiting structure also includes a third buffer limiting block 107, which is arranged on the door mounting member 104. When the door 2 is in the open position, the side of the second connecting rod 102 close to the first connecting rod 101 is pressed against the third buffer limiting block 107.

[0039] Specifically, the door mounting member 104 also includes a main body plate connected to two folding plates 1041, and the third buffer limit block 107 is specifically arranged on the main body plate and located between the two folding plates 1041. When the door 2 is in the open position, the side of the second connecting rod 102 close to the first connecting rod 101 is pressed against the third buffer limit block 107, and the third buffer limit block 107 is used to limit the maximum opening of the second connecting rod 102 to prevent the second connecting rod 102 from continuing to rotate and avoid the door from being opened too much. In addition, when the door 2 is opened, the third buffer limit block 107 also plays a role of buffering and shock absorption to reduce the shaking of the door 2 when it is opened. In addition, when the door 2 is opened and pressed, the third buffer limit block 107 can share the pressure on the fourth rotating shaft 112, avoid stress concentration, and improve the structural performance of the door hinge 1.

[0040] The first buffer limit block 105, the second buffer limit block 106 and the third buffer limit block 107 are all made of rubber. When the first buffer limit block 105, the second buffer limit block 106 and the third buffer limit block 107 are all made of rubber, the first buffer limit block 105, the second buffer limit block 106 and the third buffer limit block 107 have good buffering and shock absorbing effects.

[0041] The first buffer stopper 105 and the third buffer stopper 107 can be bonded or screwed to the door mounting member 104. The second buffer stopper 106 can be bonded or screwed to the vehicle body mounting member 103.

[0042] The door hinge provided by the embodiment of the utility model also includes an auxiliary rod 108, one end of the auxiliary rod 108 is rotatably connected to the first connecting rod 101, and the other end of the auxiliary rod 108 is connected to the first rotating shaft 109, and the first rotating shaft 109 is slidably connected to the door mounting member 104; when the door 2 is switched from the open position to the closed position, the first rotating shaft 109 slides toward the connecting rod assembly, and the auxiliary rod 108 rotates away from the vehicle body mounting member 103; when the door 2 is switched from the closed position to the open position, the first rotating shaft 109 slides away from the connecting rod assembly, and the auxiliary rod 108 rotates toward the vehicle body mounting member 103.

[0043] During the opening process of the door 2, one end of the auxiliary rod 108 rotates relative to the first connecting rod 101, and the other end of the auxiliary rod 108 rotates around the first rotating shaft 109, while the first rotating shaft 109 slides on the door mounting member 104. The auxiliary rod 108 is provided to enhance the stability of the door hinge 1 during the opening or closing process of the door 2, and prevent the connecting rod assembly from shaking during the opening or closing process of the door 2. In addition, the auxiliary rod 108 can also limit the maximum opening of the first connecting rod 101, and prevent the first connecting rod 101 from continuing to rotate after the door 2 is opened. In addition, when the door 2 is opened and pressed, the auxiliary rod 108 can disperse the pressing force, thereby improving the pressure bearing capacity of the door hinge 1.

[0044] In other embodiments, the first rotating shaft 109 is slidably connected to the vehicle door 2. The vehicle door 2 may be provided with a slide rail, and the first rotating shaft 109 is connected to the slide rail.
