[0032] The vehicle door opening and closing auxiliary structure of the embodiment of the utility model is described below in conjunction with the accompanying drawings.

[0033] like Figure 1 , Figure 2 As shown, according to the vehicle door opening and closing auxiliary structure of the embodiment of the utility model, the vehicle door opening and closing auxiliary device is applied to a vehicle, and the vehicle includes a vehicle body and a vehicle door pivotably arranged on the vehicle body. The vehicle door 20 is opened to allow passengers to enter the vehicle interior space, and the vehicle door 20 is closed to seal the vehicle interior space.

[0034] The door opening and closing auxiliary structure includes a first connecting member 30 and a second connecting member 40 .

[0035] The first connecting member 30 is used to be installed on one of the vehicle body and the vehicle door 20 . The first connecting member 30 has a first clamping portion 31 .

[0036] The second connecting member 40 is used to be movably mounted on the other of the vehicle body and the vehicle door 20 . The second connecting member 40 has a second clamping portion 41 .

[0037] For example, the first connecting member 30 is disposed on the vehicle body, and the second connecting member 40 is movably disposed on the vehicle door 20; or, the first connecting member 30 is disposed on the vehicle door 20, and the second connecting member 40 is movably disposed on the vehicle body.

[0038] Among them, the second connecting member 40 has a working state. When the second connecting member 40 is in the working state, the second clamping portion is suitable for abutting against the side of the first clamping portion away from the other of the vehicle body and the vehicle door, and the second connecting member 40 moves toward the direction of the other of the vehicle body and the vehicle door 20 to pull the vehicle door 20 closer to the vehicle body.

[0039] Specifically, the second connecting member 40 can be movably provided on the other of the vehicle body and the vehicle door 20. The second connecting member 40 is in a working state, and the second connecting member 40 moves toward the other of the vehicle body and the vehicle door 20. The second connecting member 40 is connected to the first connecting member 30, and the second connecting member 40 pulls the first connecting member 30 to move toward the other of the vehicle body and the vehicle door 20. The first clamping portion 31 is subjected to the pulling force of the second clamping portion 41, so that the vehicle door 20 is close to the vehicle body. The structure is simple and the stability is high.

[0040] For example, the second connecting member 40 can be movably provided on the vehicle body, the first connecting member 30 is provided on the vehicle door 20, the second connecting member 40 is in a working state, the second clamping portion 41 is suitable for abutting against the side of the first clamping portion 31 away from the vehicle body to facilitate force, the second connecting member 40 is connected to the first connecting member 30 and drives the first connecting member 30 to move toward the vehicle body, and the first connecting member 30 drives the vehicle door 20 closer to the vehicle body; or, the second connecting member 40 can be movably provided on the vehicle door 20, the first connecting member 30 is provided on the vehicle body, the second connecting member 40 is in a working state, the second connecting member 40 is connected to the first connecting member 30, the second connecting member 40 is subjected to a reaction force, the second connecting member 40 moves toward the vehicle body, and the second connecting member 40 drives the vehicle door 20 closer to the vehicle body.

[0041] In the related art, a vehicle body has a lock body, and a vehicle door has a lock catch, which is buckled into the lock body to fix the door to the vehicle body. Since the angle of the door and the angle of the limiter are small and a large force is required to insert the lock catch into the lock body under the reaction force of the door sealing strip, in order to smoothly press the lock catch into the lock body, the car door usually has a faster closing speed, which may cause people to be pinched or other objects to be clamped and prevent the door from closing smoothly.

[0042] In the present application, through the cooperation between the first connecting member 30 and the second connecting member, the second connecting member 40 moves toward the other direction of the vehicle body and the vehicle door 20. The vehicle door 20 does not need a large closing speed to realize the insertion of the lock buckle 21 into the lock body, thereby reducing the probability of pinching people or pinching other objects that prevent the vehicle door from closing smoothly.

[0043] According to the vehicle of the embodiment of the utility model, through the cooperation of the first clamping portion 31 on the first connecting member 30 and the second clamping portion 41 on the second connecting member 40, the second connecting member 40 moves toward the other direction of the vehicle body and the vehicle door 20, and the vehicle door 20 does not need a large closing speed to realize the insertion of the lock buckle 21 into the lock body, thereby reducing the probability of pinching people or pinching other objects to prevent the vehicle door from closing smoothly.
