Description

Technical Field

[0001] The utility model belongs to the technical field of automobiles, and in particular relates to an automobile hinge device and an automobile. Background Art

[0002] In order to reduce the space required for car door opening, some car models use a swing-opening door opening method. However, due to their own structure, such as the existing four-link swing arm hinge door, the front and rear doors need to be opened in a certain order and cannot be opened independently at will, which seriously affects the user's driving experience. In the related art, the independent opening of the car door can be achieved by adopting a five-link swing arm hinge device with a variable length, but the setting of more links makes the overall structure more complicated, which invisibly increases more potential risks, and also places higher demands on product quality, increasing production costs. Therefore, there is an urgent need to develop and design a new hinge device and car, which requires a relatively simple structure and can realize the independent opening and closing of the car door without being restricted by the structure of the other door.

[0023] The following describes the embodiments of the present invention through specific examples. Those skilled in the art can easily understand the other advantages and effects of the present invention from the content disclosed in this specification. The present invention can also be implemented or applied through different specific embodiments. The details in this specification can also be modified or changed based on different viewpoints and applications without departing from the spirit of the present invention. It should be noted that the illustrations provided in the following embodiments are only used to illustrate the basic concept of the present invention. The following embodiments and the features in the embodiments can be combined with each other without conflict.

[0024] See also Figure 1-4, this embodiment discloses a car hinge device, comprising: a first swing arm 1, wherein the two ends of the first swing arm 1 are rotatably connected to the body 6 and the door 7 respectively; a first driving assembly 2, connected to the first swing arm 1, and used to drive the first swing arm 1 to rotate; a slide rail assembly 3, arranged on the body 6 along the length direction of the body 6; a second swing arm 4, one end of the second swing arm 4 is rotatably connected to the door 7, and the other end of the second swing arm 4 can be locked, slidably and rotatably arranged on the slide rail assembly 3; a second driving assembly 5, connected to the second swing arm 4, and used to drive the second swing arm 4 to slide along the slide rail assembly (that is, slide along the sliding direction of the slide rail assembly or the guide rail); it can be imagined that when the second swing arm 4 is in a locked state, the body 6, the first swing arm 1, the second swing arm 4 and the door 7 form a four-bar linkage; here, the two ends of the first swing arm 1 are generally respectively realized by corresponding hinge shaft structures to realize rotation with the body 6 and the door 7. The first drive assembly 2 is dynamically connected, and the second swing arm 4 can also be rotatably connected to the vehicle door 7 through a hinge shaft; the structure of the first drive assembly 2 is not limited here, and it can provide torque for the first swing arm 1. Preferably, the first drive assembly 2 here adopts a drive motor structure equipped with a reduction gear set, and the first drive assembly 2 can be installed and arranged with reference to the drive structure of the existing four-link hinge swing arm vehicle door, which will not be repeated here; it can be understood that the slide rail assembly 3 is arranged along the length direction of the vehicle body 6, that is, the guide rail or sliding direction of the slide rail assembly 3 is arranged along the length direction of the vehicle body 6, and the length direction of the vehicle body 6 is also the front and rear direction of the vehicle; when the second swing arm 4 is in a locked state, it means that the sliding freedom of the second swing arm 4 is locked; of course, it can be understood that the four-bar linkage formed by the vehicle body 6, the first swing arm 1, the second swing arm 4 and the vehicle door 7 is the same as the traditional automobile four-link hinge device, which can realize the smooth swinging opening of the vehicle door, and will not be repeated here;

[0025] The above-mentioned automobile hinge device can be used for automobile rear doors, and of course it can also be used for automobile front doors, and it only needs to make adaptive adjustments in the structure. Here, the structure when applied to automobile rear doors is taken as an example to illustrate the implementation principle of the device: in the initial stage of opening the rear door, the first driving component 2 drives the first swing arm 1 to rotate, and at the same time drives the rear door to swing open. In order to avoid collision and interference with the front door, the second driving component 5 simultaneously drives the corresponding end of the second swing arm 4 to slide backward, so that the front end of the rear door (that is, near the B-pillar position) can be directly moved backward to separate from the front door, and the rear end of the rear door is in a tilted posture at the C-pillar position; when the rear door can be separated from the front door by a certain distance, the position of the second swing arm 4 can be locked on the slide rail component 3, and then the opening method is the same as that of a traditional four-link hinge door, which will not be repeated here; of course, the closing process of the rear door is opposite to the opening process, which will not be repeated here;

[0026] The automobile hinge device in the above structural design has a simple structure and can realize the independent opening and closing of the automobile door without being restricted by the structure of the other door. Specifically, the device designs a connection point between the traditional four-link swing arm hinge and the vehicle body 6 into a sliding and rotatable structure that can be locked. In the initial stage of door opening or the final stage of door closing, the position of the connection point can be changed by the second drive component 2, thereby realizing the movement of the door 7 along the front and rear direction of the vehicle body 6, avoiding interference with other vehicle doors and other components, thereby realizing the independent and arbitrary opening of the door 7. The device adopts a slide rail + swing arm The structural form is the same as the structure of a traditional automobile four-bar hinge device after the relative sliding position of the second swing arm 4 and the slide rail assembly 3 is locked. The overall structure is simple, the number of links is small, the operation stability is high, the failure rate is low, and it is beneficial to save production costs; in addition, this device is conducive to realizing the trajectory control of the car door 7 near the B-pillar position of the car, and can directly realize the direct forward or backward movement control of the car door 7 near the B-pillar position, thereby helping to reduce the wear on the door opening sealing strip; in addition, the structure of this device is easy to develop, and the height of the car door tilting can be controlled by adjusting the sliding distance of the second swing arm 4 on the slide rail assembly 3.

The electric push rod can drive the sliding bracket body 801 to slide by extending and retracting. The electric push rod is small in size, which is conducive to layout and installation on the vehicle body.

[0034] In this embodiment, a connecting ball head 801a is provided on the sliding bracket body 801, and the telescopic end of the electric push rod is connected to the connecting ball head 801a; specifically, the connecting ball head 801a here can be fixed with the sliding bracket body 801 by welding or clamping.
