Description

Technical Field

[0001] The utility model relates to a hinge structure and a sliding door driving mechanism, and in particular to a hinge structure and a sliding door driving mechanism for a vehicle. Background Art

[0002] In the prior art, for example, see Patent Documents 1 and 2, which describe hinge structures and sliding door drive mechanisms for vehicles, wherein a motor drives a cable, thereby utilizing a hinge connected to a cable bracket to which the cable is fixed to drive the sliding door to move.

[0003] Prior art literature

[0004] Patent document 1: Chinese invention patent CN116084790A.

[0005] Patent document 2: Chinese utility model patent CN211222987U.

[0006] However, Patent Documents 1 and 2 have the following problems.

[0007] First, the wire bracket and the hinge are formed separately, there are many parts and the assembly is complicated.

[0008] Secondly, the door opening and closing cables are arranged at the same position in the up and down directions of the vehicle. Therefore, the door opening and closing cables rub against the cable baffle at the same position. After long-term use, the surface treatment of the cable baffle will cause abnormal wear, resulting in reduced corrosion resistance and reduced aesthetics.

[0009] In addition, the door opening and closing cables are both arranged under the guide rails. The cable bracket is longer in the front-to-rear direction of the vehicle, which affects the arrangement of the rear pulley seat when the door is fully open, and affects the maximum opening stroke of the door. Utility Model Content

[0010] The purpose of the utility model is to provide a hinge structure and a sliding door driving mechanism, which can improve the durability of the sliding door and reduce costs without affecting the maximum door opening stroke with a simple structure.

[0011] A hinge structure of a technical solution of the present invention is applied to a sliding door and comprises a hinge body, one end of the hinge body being connected to the sliding door, a load-bearing wheel being provided at the other end of the hinge body, and a door closing cable end connected to the door closing cable and a door opening cable end connected to the door opening cable being provided at the hinge body. When the door closing cable or the door opening cable is driven by a motor, the hinge body is pulled so that the load-bearing wheel slides along a guide rail to drive the sliding door to open and close, and at least the portion of the hinge body comprising the door closing cable end, the door opening cable end, the one end and the other end is an integrally formed part.

[0012] According to this technical solution, since at least the door pull wire end, the door opening pull wire end, one end and the other end of the hinge body are formed as an integrally formed part, the functions of the pull wire fixing bracket and the hinge are concentrated on one part, which can reduce the number of parts, reduce the installation time, improve the installation efficiency and reduce the cost.

[0013] In the above technical solution, preferably, the hinge body is an integrally formed part.

[0014] This can further reduce the number of parts.

[0015] In the above technical solution, preferably, the door closing wire end and the door opening wire end are arranged at different positions in the up and down directions.

[0016] As a result, the closing cable connected to the closing cable end and the opening cable connected to the opening cable end contact the guide rail at different locations in the vertical direction, effectively reducing wear on the guide rail surface treatment. Furthermore, the vertical separation of the opening and closing cable allows the hinge, which functions as the cable fixing bracket, to be shortened in the vehicle's fore-and-aft direction. When the door is fully open, the hinge does not interfere with the placement of the rear pulley seat, nor does it affect the maximum door opening travel.

[0017] In the above technical solution, preferably, the door opening wire end is arranged above the door closing wire end.

[0018] Thus, the door opening wire end and the door closing wire end can be separately arranged with a simple structure.

[0019] In the above technical solution, preferably, a guide wheel is further provided on the hinge body, which guides the movement of the hinge body along the guide rail, and the door opening cable end is arranged below the guide wheel in a coaxial manner with the guide wheel.

[0020] Therefore, by arranging the door opening cable end coaxially with the guide wheel, the length of the hinge in the front-rear direction of the vehicle can be further reduced.

[0021] Another technical solution of the present invention is a sliding door driving mechanism comprising the hinge structure, the door closing cable, the door opening cable, a motor and the guide rail. BRIEF DESCRIPTION OF THE DRAWINGS

[0044] Below, using Figures 1 to 5 The hinge structure 2 and the sliding door driving mechanism 10 in the preferred embodiment of the present invention will be described in detail.

[0045] The sliding door driving mechanism 10 of this embodiment is applied to a sliding door of a vehicle. The sliding door driving mechanism 10 opens and closes the sliding door based on the driving force generated by the actuator using the motor 7 as a driving source. Figure 5In this embodiment, the side of the guide rail 12 where the rear pulley seat 6 is provided is the rear side in the vehicle front-rear direction, and a curved portion that curves inward in the vehicle width direction is formed at the front end of the guide rail 12 in the vehicle front-rear direction. Figure 4 The up-down direction on the paper corresponds to the up-down direction of the vehicle (up-down direction).

[0046] The sliding door driving mechanism 10 comprises a hinge structure 2, a door closing cable (not shown), a door opening cable 9, a motor 7 and a guide rail 12. The guide rail 12 is mounted on the vehicle body.

[0047] The hinge structure 2 includes a hinge body 22. In this embodiment, the hinge body 22 is a one-piece molded component. More specifically, it is a one-piece molded plate. One end 22a of the hinge body 22 is connected to the sliding door, and a load-bearing wheel 24 is provided at the other end 22b of the hinge body 22. Specifically, one end 22a of the hinge body 22 is connected to the sliding door pivot via a connecting mechanism (not shown). The load-bearing wheel 24 provided at the other end 22b of the hinge body 22 slides along the guide rail 12, thereby driving the hinge body 22 to move along the guide rail 12.

[0048] The hinge body 22 is also provided with a front guide wheel 25f and a rear guide wheel 25r (guide wheels). The front guide wheel 25f and the rear guide wheel 25r guide the movement of the hinge body 22 along the guide rail 12. Specifically, the front guide wheel 25f and the rear guide wheel 25r are arranged in the front-to-back direction of the vehicle. The front guide wheel 25f and the rear guide wheel 25r slide in the guide grooves in the guide rail 12, so that the load-bearing wheel 24 can slide without deviating from the guide rail 12.

[0049] The hinge body 22 is further provided with a door closing wire end 81 connected to the door closing wire and a door opening wire end 91 connected to the door opening wire 9 .

[0050] Specifically, a door closing wire end mounting component for mounting the door closing wire end 81 is provided on the hinge body 22. The door closing wire end mounting component is, for example, an axis provided in a manner protruding from the hinge body 22. The door closing wire is mounted on the door closing wire end 81. The door closing wire end 81 is mounted on the door closing wire end mounting component and is connected to the hinge body 22.

[0051] In addition, a door opening pull wire end terminal mounting component for mounting the door opening pull wire end terminal 91 is provided on the hinge main body 22. The door opening pull wire end terminal mounting component is, for example, an axis provided in a manner protruding from the hinge main body 22 (in this embodiment, the axis of the door opening pull wire end terminal mounting component is coaxial with the axis 25s described below). The door opening pull wire 9 is mounted on the door opening pull wire end terminal 91, and the door opening pull wire end 91 is mounted on the door opening pull wire end terminal mounting component and connected to the hinge main body 22.

[0052] The door closing cable end 81 and the door opening cable end 91 are arranged at different positions in the vehicle vertical direction. In this embodiment, the door opening cable end 91 is arranged above the door closing cable end 81 in the vehicle vertical direction.

[0053] The door opening cable end 91 is coaxially disposed below the rear guide wheel 25r. More specifically, the door opening cable end 91 and the rear guide wheel 25r share the same axis 25s. However, the coaxial arrangement of the door opening cable end 91 and the rear guide wheel 25r is merely an example; the door opening cable end 91 may also be disposed non-coaxially with the guide wheel.

[0054] The door closing cable is led out through the door closing cable sleeve 80 and is led to a front pulley (not shown) provided on the vehicle inner side of the curved portion of the guide rail 12 . After being guided by the front pulley, it is connected to the door closing cable end 81 and fixed to the hinge body 22 .

[0055] The door opening cable 9 is led out through the door opening cable sleeve 90 and is led to the rear pulley arranged on the rear pulley seat 6. After being guided by the rear pulley, it is connected to the door opening cable end 91 and fixed to the hinge body 22.

[0056] The motor 7 is connected to the door opening cable 9 and the door closing cable. When the door closing cable or the door opening cable 9 is driven by the motor 7, the hinge body 22 is pulled, thereby the load-bearing wheel 24 slides along the guide rail 12 and drives the sliding door to open and close.

[0057] In this embodiment, the hinge body 22 of the hinge structure 2 is formed by an integrally molded part, which can integrate the functional structure of the hinge structure 2 connecting to the vehicle body and the functional structure of fixing the pull wire into one part, reducing the number of parts and reducing the installation process.

[0058] In this embodiment, the door closing cable end 81 and the door opening cable end 91 are vertically separated, so that the door closing cable and the door opening cable contact different portions of the guide rail in the vertical direction, thereby reducing the amount of wear on the same portion of the guide rail 12. In addition, because the door closing cable end 81 and the door opening cable end 91 are vertically separated, the length of the hinge body 22 in the vehicle front-to-rear direction corresponding to the cable fixing bracket functional portion can be designed without affecting the maximum door opening stroke.

[0059] While preferred embodiments of the present invention have been described above, various modifications are possible in these embodiments.

[0060] For example, in the above embodiment, the sliding door driving mechanism is shown as being used in a vehicle, but the present invention is not limited thereto, and the sliding door driving mechanism can be applied to any sliding door.

[0061] For example, in the above embodiment, an example is shown in which the hinge body 22 is an integrally molded part, but the present invention is not limited to this. As long as at least the door pull wire end 81, the door opening pull wire end 91, one end 22a (connected to the vehicle body) and the other end 22b (provided with a load-bearing wheel) of the hinge body 22 are an integrally molded part, for example, the part with the guide wheel can also be formed separately from the hinge body.

[0062] For example, in the above embodiment, an example is shown in which the door opening wire end 91 is arranged above the door closing wire end 81 , but the present invention is not limited thereto, and the door closing wire end 81 may also be arranged above the door opening wire end 91 .

[0063] For example, in the above embodiment, an example is shown in which the door opening wire end 91 is coaxially arranged with the rear guide wheel 25r, but the present invention is not limited to this, and the door opening wire end 91 may also not be coaxially arranged with the guide wheel.

[0064] The present invention has been described above with reference to a specific example. However, the present invention is not limited to this specific example. Any design obtained by a person skilled in the art by making appropriate design changes to this specific example, as long as it has the characteristics of the present invention, is also included in the scope of the present invention.
