Description

Technical Field

[0001] The invention relates to an automobile component, in particular to a rotatable electric sliding door hinge driving structure. Background Art

[0002] As time goes by, the speed of social development is changing with each passing day. Cars have become an indispensable means of transportation for people. With the development, consumers are also paying more attention to the quality of cars, especially the quality of high-end commercial vehicles.

[0003] There are two deficiencies in the drive connection structure of the electric sliding door hinge assembly of MPVs on the market:

[0004] 1. The installation structure of the center drive cable and the center hinge will increase the Y-direction space occupied by the center drive front guide wheel in the vehicle, affecting the passenger space and the aesthetics of the space.

[0005] 2. At present, it is difficult to install and disassemble the center hinge and drive cable of most mid-drive MPVs on the market. a. The cable needs to be connected to the center hinge first and then installed in the guide rail, which means that the center hinge can only be installed in one fixed way. If the center hinge is installed on the door first, the drive cable cannot be installed. b. The traditional structure also makes it difficult to disassemble the center hinge. In order to ensure that the vehicle does not loosen or make abnormal noises during use, the center drive cable is connected to the center hinge. The drive cable has a tensioning force. The traditional hinge cannot remove the cable bracket first and then the center hinge. Therefore, when removing the center hinge, you must overcome the cable tensioning force and remove the center hinge before removing the cable. Summary of the invention

[0006] The present invention aims to provide a rotatable electric sliding door hinge driving structure which does not affect the appearance and the use space and is easy to install.

[0007] A rotatable electric sliding door hinge drive structure in the present embodiment includes a hinge body, one end of the hinge body is used to connect with the door body, and the other end of the hinge body is used to slide with a guide rail. The end of the hinge body that is slidably connected with the guide rail is also rotatably provided with at least one wire bracket, and the wire bracket is used to connect with the wire.

[0008] Furthermore, the wire pulling bracket includes a bracket plate and a wire pulling connector disposed on the bracket plate, the bracket plate is rotatably connected to the hinge body, and the wire pulling connector is used to be connected to the wire.

[0009] Furthermore, the pull wire connecting member includes a first pull wire connecting column and a second pull wire connecting column, and the top end surfaces of the first pull wire connecting column and the second pull wire connecting column are both provided with a pull wire connecting hanging head.

[0010] Furthermore, the column body of the first wire connecting column is fixedly connected to the hinge body, and the column body of the first wire connecting column is rotatably connected to one end of the bracket plate; the second wire connecting column is fixedly arranged at the other end of the bracket plate.

[0011] Furthermore, the column body of the first wire connecting column is rotatably connected to the hinge body, and the column body of the first wire connecting column is fixedly connected to one end of the bracket plate; the second wire connecting column is fixedly arranged at the other end of the bracket plate.

[0012] Furthermore, the hinge body includes a bearing bracket, a hinge bearing seat, a load-bearing wheel connecting plate and a guide wheel connecting plate, the hinge bearing seat is arranged at one end of the bearing bracket, the other end of the bearing bracket is the load-bearing wheel connecting plate, the upper left and upper right of the load-bearing wheel connecting plate are the guide wheel connecting plate, and a wire bracket connecting plate is extended outward from one side of the load-bearing wheel connecting plate; the upper and middle part of the column body of the first wire connecting column is interference fit with the wire bracket connecting plate, and the lower part of the column body of the first wire connecting column is rotatably connected to one end of the bracket plate.

[0013] Furthermore, the lower part of the column body of the first pull-wire connecting column is rotationally matched with the bracket plate through a bushing, and the bushing is sleeved on the column body of the first pull-wire connecting column.

[0014] Furthermore, the middle portion of the bracket plate is hinged to the hinge body, and the first pull-wire connecting column and the second pull-wire connecting column are respectively arranged at two ends of the bracket plate.

[0015] Furthermore, there are two wire pulling brackets, and the first wire pulling connecting column and the second wire pulling connecting column are respectively arranged on one of the wire pulling brackets.

[0016] Furthermore, a sliding mechanism is provided at the free end of the wire support.

[0017] The advantages of the present invention are:

[0018] 1. While the cable bracket avoids the driving guide wheel in the X direction, a rotating structure is added to enable the cable bracket to move together with the driving cable, so as to solve the problem that the fixed cable bracket exceeds the vehicle body shape surface at the turning position of the guide rail, which can improve the product appearance and control the product consistency.

[0019] 2. Since the cable bracket can rotate, the component force of the driving cable on the front guide wheel of the middle hinge can be reduced, thereby increasing the service life of the middle hinge guide wheel. The cable bracket changes with the posture of the vehicle body, and the direction of the pulling force becomes smaller, which can reduce the component force.

[0020] 3. Adding a sliding mechanism to the wire bracket can reduce sliding noise.

[0021] 4. This hinge drive structure can avoid the front guide wheel of the mid-drive, save the Y-direction space in the car, and realize the process of installing the hinge first and then the wire drawing.

[0022] 5. The installation of the middle hinge is more labor-saving and convenient: Since the rear cable connection point is at the rear end of the middle hinge, you can first connect the front cable to the middle hinge, and then install the middle hinge into the guide rail. During the installation process, there is no tension on the cable, and finally connect the rear cable. For disassembly, just reverse the order. BRIEF DESCRIPTION OF THE DRAWINGS
