[0031] Embodiment 1
[0032] As Figures 2-4 The utility model provides a swing arm car door hinge system, including main hinge (not shown), auxiliary hinge 5 and hinge mounting seat 6, hinge mounting seat 6 includes mounting seat body 601, sliding rail 602 and trajectory limiting structure 603, and sliding rail 602 and trajectory limiting structure 603 are all arranged on mounting seat body 601;
[0033] The main hinge is used to make the movement trajectory of the car door produce the stroke of trajectory direction change;
[0034] One end of the auxiliary hinge 5 is rotatably connected with the vehicle body 7, and the other end of the auxiliary hinge 5 includes a rotating shaft 501 and a pin 502; the rotating shaft 501 is arranged in the sliding rail 602 and can slide in the sliding rail 602 to cooperate with the stroke of trajectory direction change;
[0035] The pin 502 is arranged in the trajectory limiting structure 603 and can slide in the trajectory limiting structure 603 to cooperate with the stroke of trajectory direction change, and when the movement trajectory of the car door is not in the stroke of trajectory direction change, the movement of the other end of the auxiliary hinge 5 is limited to rotation around the rotating shaft 501.
[0036] The above-mentioned system cooperates the main hinge, the auxiliary hinge with specific structure and the hinge mounting seat with specific structure, so that the car door can produce the stroke of trajectory direction change when being opened or closed to the other car door, interference with the other car door is avoided, and at the same time, the other end of the auxiliary hinge is limited to rotation around the rotating shaft in the stroke of non-trajectory direction change, so that the car door is prevented from shaking in the opening and closing process, thereby improving the opening and closing stability and durability of the car door. The main hinge bears the main pressure in the opening and closing process of the car door, and limits the movement trajectory of the car door to form the stroke of trajectory direction change, and the whole can be arranged below the auxiliary hinge to provide stable car door sliding. At the same time, due to the existence of the sliding rail in the auxiliary hinge, the auxiliary hinge can produce the avoiding trajectory relative to the other car door when the sliding door is opened, and after the avoiding is completed, the normal circular opening process is carried out. In addition, the trajectory limiting structure makes the sliding rail realize its function, and avoids the shaking of the door caused by external force.
[0037] In this embodiment, the main hinge can be located below or above the auxiliary hinge 5, but the two are not connected. The main hinge cooperates with the auxiliary hinge to make the process of opening or closing the door more stable.
[0038] As Figure 1 shown is the movement trajectory of the swing arm door hinge system of this embodiment and the swing arm door hinge system of the prior art when the door is opened. It can be seen that the movement trajectory 3 formed by the four-bar linkage door swing arm system has only one direction, that is, the trajectory direction is not variable. The sliding door 1 will interfere with the other door 2. The movement trajectory 4 formed by the swing arm door hinge system of this embodiment has two directions. There is a trajectory direction change stroke in the entire movement trajectory to avoid the front door.
[0039] Alternatively, as Figure 3 and Figure 4 shown, the slide rail 602 is arranged on the side of the mounting seat body 601 close to the door 8, and the trajectory limiting structure 603 is arranged on the side of the mounting seat body 601 away from the door 8. The slide rail and the trajectory limiting structure are arranged in the above manner to make the movement of the auxiliary hinge more smooth.
[0040] Alternatively, the slide rail 602 is in the shape of a long strip. The slide rail is arranged in the shape of a long strip to facilitate the sliding and rotation of the shaft therein.
[0041] Alternatively, the trajectory limiting structure 603 includes a long strip structure 6031 and an arc structure 6032 connected to each other. When the door movement trajectory is within the stroke of the trajectory direction change, the pin 502 slides in the long strip structure 6031. When the door movement trajectory is not within the stroke of the trajectory direction change, the pin 502 slides in the arc structure 6032. The door movement trajectory generated when the pin slides in the long strip structure is the stroke of the trajectory direction change. The door movement trajectory generated when the pin slides in the arc structure is the stroke of the non-trajectory direction change. The movement of the pin cooperates with the movement of the shaft to generate the stroke of the trajectory direction change and keep the door stable, thereby improving the perception quality of the opening and closing process of the door.
[0042] Alternatively, as Figure 2 and Figure 4 shown, the system further includes a latch 9 arranged on the door 8. The latch 9 is used to cooperate with a latch seat 10 on the vehicle body 7 to achieve the locking of the door 8. The locking effect achieved by the cooperation of the latch and the latch seat includes preventing the door from opening when pushed from the inside to the outside and preventing the door from intruding into the vehicle when a side impact occurs.
[0043] Alternatively, the latch 9 is arranged at the starting end of the opening direction of the door 8. When the latch is arranged at the starting end of the opening direction of the door, the latch seat is also arranged at the corresponding position, which is more consistent with the actual use of the vehicle.
[0044] Optionally, the overlapping length of the bolt and the bolt seat is greater than 20mm when the door 8 is in the locked state. The overlapping length refers to the length of the overlapping of the bolt and the bolt seat in the horizontal direction. When the overlapping length is greater than 20mm, on the one hand, a better locking effect can be achieved, and on the other hand, the stroke of the trajectory direction change can be greater than 20mm, so that the stroke is longer.
[0045] In the prior art, the stroke length of the trajectory direction change is reduced to reduce the deformation of the door, but this will result in a smaller overlapping length of the bolt and the bolt seat arranged in the vehicle length direction at the B-pillar end of the door, and the smaller overlapping length will not achieve the locking effect of the bolt. The embodiment solves the problem of the locking effect of the bolt.
[0046] Optionally, one end of the main hinge is connected to the vehicle body, and the other end is connected to the door.
[0047] Optionally, the main hinge comprises a five-link hinge or the same structure as the auxiliary hinge. The main hinge in the embodiment can select a five-link hinge or the same structure as the auxiliary hinge. These hinge structures will generate a stroke of the trajectory direction change by themselves, and will not affect the opening and closing effect of the door of the embodiment.
[0048] The main hinge described above can also be a single pendulum arm hinge and a telescopic rod connected to each other. One end of the single pendulum arm hinge is connected to the vehicle body, and the other end is connected to the telescopic rod. The other end of the telescopic rod is connected to the door. The main hinge forms a three-link form through the extension and rotation of the telescopic rod.
[0049] It can be understood that the swing arm door hinge system of the embodiment further comprises a driving device (such as a driving motor) connected to the main hinge to provide power for the opening and closing of the door.
[0050] Embodiment 2
[0051] The embodiment provides an automobile comprising a door and the swing arm door hinge system of embodiment 1, wherein the door is connected to the hinge mounting seat.
[0052] Further, the door is further connected to the bolt and the main hinge, respectively.
[0053] It can be understood that the focus of the embodiment is to contain the swing arm door hinge system described above, and therefore at least has the same advantages as the swing arm door hinge system described above. As for the cooperation relationship between the swing arm door hinge system and other components on the automobile and the cooperation relationship between the other components on the automobile, the embodiment does not make special limitations, and any one of the cooperation relationships that can be realized in the art can be adopted.
[0054] Finally, it should be noted that: the above embodiments are used to illustrate the technical solutions of the present application, but not limited to them; although the present application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that: it can still modify the technical solutions recorded in the foregoing embodiments, or make equivalent replacement to part or all of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the technical solutions of the embodiments of the present application.
