A sliding oblique insertion type single-leaf sliding door mechanism for passenger cars

Abstract

The invention provides a sliding and oblique insertion type single sliding door mechanism for a passenger car. The sliding and oblique insertion type single sliding door mechanism for the passenger car includes driving actuating mechanisms, a fixed track door shaft, door body of a passenger door and a side wall of a car body. The driving actuating mechanisms are installed on the door body of the passenger door and the side wall of the car body simultaneously. The driving actuating mechanisms drive the door body of the passenger door to rotate through the fixed track door shaft. The action posture of "flat sliding, oblique insertion and pull back locking" of the passenger door is achieved, the problem of the discomfort of ears of a passenger caused by the sudden change of the internal pressure of the vehicle due to the overall movement of the door when the door is just opened or is to be closed while an existing sliding door is used in the small interior space of vehicles is solved. Atthe same time, compared with existing single sliding door series, the innovative door opening and closing action postures carried out by the novel sliding and oblique insertion type single sliding door mechanism can further improve the anti-pinching safety of the passenger door when the door is to be closed.

Description

technical field [0001] The invention belongs to the field of passenger car parts, and in particular relates to a sliding oblique insertion type single-leaf sliding door mechanism for passenger cars. Background technique [0002] With the gradual improvement of people's living standards, the public's expectations for product quality, function and safety performance are also getting higher and higher. It can enhance the competitiveness of the enterprise itself and establish itself as a leader in this field. [0003] At present, several parts companies in the passenger car industry have their own high-end sliding door products. Although the structure is obviously different, the gestures of the passenger door are basically the same, that is, "translational sliding + overall pull back" (this For the door closing action sequence, the door opening action is opposite, the same below) or "translational sliding + overall swing pull back", the market performance is nothing more than g...

Problems solved by technology

[0010] However, in the above-mentioned closing action posture of the passenger door, that is, "translational sliding + overall pull back" or "translational sliding + overall swing pull back", in the final stage of closing the passenger door, the passenger door body uses a relatively high The speed is pulled back as a whole and closed with the body. For a passenger car with a small interior space, if the other doors and windows in the car are closed, the air pressure inside the car will be forced to increase instantaneously during the process of the passenger door being pulled back as a whole, which will cause Passenger's ear discomfort; on the contrary, in the same environment, when the passenger door performs the opening action posture, the air pressure in the car drops instantaneously at the initial stage of opening the passenger door, which will also cause passenger ear discomfort

[0011] Defects in the prior art also include: when the passenger door is in the final stage of the door closing action, that is, when the "integral pull back" or "integral swing pull back" action is performed, the current anti-pinch strategy on the four edges of the passenger door is canceled at the same time, and all of them are in the passenger door. When the distance between the door and the body is 30mm, it must be canceled, and the safety is average; when the passenger door mechanism works in the final stage of door closing and the initial stage of door opening, the internal resistance of the mechanism is very large, and the strength of the load-bearing parts is very high, and the load-bearing parts are designed very well. Strong, it will further increase the weight of the mechanism assembly, and the lightweight effect is poor; the horizontal and vertical dimensions of the passenger door drive mechanism are large, occupying a lot of space in the air duct in the car, which will reduce the degree of freedom in the design of the air duct section, and it is easy to cause damage to surrounding parts. Interference; the existing sliding door mechanism requires high assembly precision, high component dimensional precision, high assembly cost, and difficult market promotion
