[0036] The following combines the accompanying drawings to give a preferred embodiment of the present invention and describes it in detail.

[0037] In this article, the horizontal coordinate axis (i.e., the X direction) is oriented along the longitudinal direction of the vehicle (i.e., the driving direction), the vertical coordinate axis (i.e., the Y direction) is oriented along the transverse direction of the vehicle, and the vertical axis (Z direction) is oriented along the height direction of the vehicle.

[0038] As Figure 1 - Figure 2 shown, the window lifter device for supplying power to an automotive glass according to a preferred embodiment of the present utility model includes a carrier plate 1, a guide rail 2, a sliding bracket 3, a guiding member 4, a wire harness assembly 5, and a connecting member 6. Among them, the guide rail 2 is fixedly installed or integrally formed on the carrier plate 1. As Figure 3 shown, the window glass A is loaded on the sliding bracket 3 through a clip 31. The sliding bracket 3 is movably installed on the guide rail 2 to guide and drive the window glass A to move in a curve in the Z direction. As Figure 4 shown, the guiding member 4 is fixedly installed on the carrier plate 1 parallel to the guide rail 2. The wire harness assembly 5 is guided by the guiding member 4 while being abutted against the limiting groove structure of the guiding member 4. The connecting member 6 fixedly connects the sliding bracket 3 and the wire harness assembly 5. In this embodiment, as Figure 1 shown, the wire rope 32 for driving the sliding bracket 3 is located on the right side of the guide rail 2, while the guiding member 4 is located on the left side of the guide rail 2. It should be understood that the wire rope 32 and the guiding member 4 are respectively located on different sides of the guide rail 2.

[0039] As Figure 5 shown, the guiding member 4 includes a bottom plate 41, a first flanging 42, and a second flanging 43. Among them, the bottom plate 41 is fixedly installed on the carrier plate 1 through three mounting points 411. The first flanging 42 and the second flanging 43 respectively extend vertically upward from opposite sides of the bottom plate 41 and extend towards each other to form an L-shaped flanging to define the limiting groove structure. It should be understood that the mounting points 411 are screw mounting holes or snap connection structures. The three mounting points are only examples rather than limitations, and more than two mounting points are feasible.

[0040] As Figure 6 shown, the first flanging 42 and the second flanging 43 respectively have an X-direction stop edge 4a and a Y-direction stop edge 4b. Among them, the X-direction stop edge 4a extends vertically upward from the bottom plate 41, and the Y-direction stop edge 4b extends inwards from the top end of the X-direction stop edge 4a. In this embodiment, the free end 431 of the Y-direction stop edge 4b of the second flanging 43 tilts upwards along the Y direction towards the first flanging 42, that is, the Y-direction stop edge 4b of the second flanging 43 is inclined. In this embodiment, there is a flanging gap L between the Y-direction stop edge 4b of the first flanging 42 and the Y-direction stop edge 4b of the second flanging 43.

[0041] In this embodiment, the first flanging 42 and the second flanging 43 are continuous flangings. As Figure 5 shown, so that the guiding member 4 wraps around the wire harness assembly 5. In another embodiment, the first flanging 42 and the second flanging 43 are segmented flangings. As Figure 7As shown, that is, the first flanging 42 and the second flanging 43 are not a continuous whole section, but a multi-section flanging, so that the wire harness assembly 5 is accommodated in the guide 4 in part of its length and / or in a sectional manner. It should be understood that the first flanging 42 and the second flanging 43 each have at least one segment. For example, in Figure 7 In the embodiment, the first flanging 42 has three segments, and the second flanging 43 has four segments.

[0042] As Figure 8 shown, the wire harness assembly 5 includes a cable 51 and a drag chain 52. Among them, the cable 51 is accommodated in the drag chain 52 to guide and limit the cable 51 through the drag chain 52. The drag chain 52 abuts against the limiting groove structure of the guide 4 and is limited and guided by the X-direction stop edge 4a and the Y-direction stop edge 4b of the first flanging 42 and the second flanging 43. It should be understood that the drag chain 52 is placed vertically and will shake in the X-direction and Y-direction without limitation. If not constrained, when the vehicle is running, the mechanism may make impact noises, and in severe cases, it may cause the mechanism to fail to work. In another embodiment, the drag chain 52 can be replaced by a hose 52a, as Figure 9 shown.

[0043] As Figure 8 shown, the drag chain 52 has a minimum bending radius R, and the drag chain 52 cannot be bent with a radius less than R. As Figure 10 shown, the drag chain 52 will not sweep out from the flanging gap L during operation. The X-direction movement of the drag chain 52 is limited by the X-direction stop edge 4a of the first flanging 42 and the second flanging 43, and no abnormal noise will be generated in the X-direction due to vibration. There is an assembly gap M between the drag chain 52 and the guide 4. This gap provides the necessary operating space for the drag chain 52, avoids operating jams, and reduces frictional resistance and abnormal noises.

[0044] In this embodiment, the opposite ends of the cable 51 are connected with a first connector 511 and a second connector 512. Among them, the first connector 511 is fixedly connected to the electronic device, and the second connector 512 is plugged into the connector A1 at the glass end, as Figure 3 shown.

[0045] In this embodiment, the drag chain 52 is formed by connecting several hollow plastic parts. One end 521 of it is fixedly connected (for example, by clamping or screws) inside the guide 4, and the opposite end forms a mobile end 522.

[0046] As Figure 11 shown, the whole of the guide 4 has a certain curvature, and the curvature matches the curvature of the guide rail 2. This is because the mobile end 522 of the drag chain 52 moves along with the sliding bracket 3, and the running track of the sliding bracket 3 is defined as an arc by the guide rail 2. If the guide 4 is not an arc, there will be a movement interference in the Y-direction. Specifically, as Figure 12As shown, when the drag chain 52 runs along the track 20 of the guide rail 2, the track 20 is curved. If the guide member 4 is straight or has a curvature inconsistent with that of the guide rail 2, there will be a large interference between the track 520 of the drag chain 52 and the structure of the guide member 4, resulting in jamming or even functional failure of the mechanism operation. For example Figure 13 As shown, if the radian of the guide member 4 is consistent with the curvature of the guide rail 2, there will be no interference between the track 520 of the drag chain 52 and the structure of the guide member 4. Therefore, there will be no jamming during operation. And there is an assembly gap M between the drag chain 52 and the guide member 4 (see Figure 10 ). The drag chain 52 has a certain bending toughness in the Y direction. Therefore, the state of the drag chain 52 in the guide member 4 is that both the upper and lower sides (at P and Q) are limited. That is, the bottom of the drag chain 52 is slightly attached to the guide member 4 under its own bending stress and will not shake and make abnormal noises.

[0047] For example Figure 5 As shown, at least one sewage discharge port 412 is distributed on the bottom plate 41 of the guide member 4, which can discharge foreign matters or water in the guide member 4 when the drag chain 52 moves. Specifically, as Figure 14 shown, the optimal position of the sewage discharge hole is in the middle of the range of the bending radius R of the drag chain 52, and there is a gap 10 between the guide member 4 and the carrier plate 1. As Figure 15 shown, the foreign matters or water falling into the guide member 4 can be discharged from the sewage discharge port 412 when the drag chain 52 moves up and down.

[0048] For example Figure 16 As shown, the connecting member 6 has a first connection port 61, a second connection port 62 and a third connection port 63. Among them, the sliding bracket 3 is fixedly connected to the connecting member 6 through the first connection port 61, the second connector 512 of the cable 51 of the wire harness assembly 5 is fixedly connected to the connecting member 6 through the second connection port 62, and the mobile end 522 of the drag chain 52 of the wire harness assembly 5 is fixedly connected to the connecting member 6 through the third connection port 63. In this embodiment, the first connection port 61 is of a screw type or a clamping type structure, the second connection port 62 is of a plug-in component installation structure, and the third connection port 63 is of a screw type or a clamping type. In addition, the connecting member 6 also has a cable slot 64, and the cable 51 of the wire harness assembly 5 is clamped in the cable slot 64 to prevent the wire harness from loosening. As Figure 17 shown. It should be understood that the positions and structures of the connection ports shown here are only examples and not limitations.

[0049] For example Figure 5 As shown, the bottom of the second flanging 43 of the guide member 4 has a flared guiding structure 432 to facilitate the guiding when the drag chain 52 enters the notch. As Figure 18 shown, during the operation of the sliding bracket 3, it is affected by the steel wire rope 32 (see Figure 1) Under the action of the pulling force, the sliding bracket 3 will deflect and swing in a small range around the tangent of the guide rail 2, because the connecting member 6 is fixed to the sliding bracket 3, and the moving end 522 of the drag chain 52 is fixed to the connecting member 6. If the sliding bracket 3 deflects and swings, it will drive the moving end 522 of the drag chain 52 to deflect accordingly, which will not only cause the drag chain 52 to be subjected to unnecessary reaction force in the guide member 4, reducing the durability of the mechanism, but also affect the entry of the drag chain 52 into the groove. In order to solve the negative impact caused by the deflection of the sliding bracket 3 during operation, the bell-mouth guide structure 432 is used to guide the drag chain 52 when it enters the slot, and through the tilting of the second flange 43 (see Figure 6 ) to compensate for the offset of the drag chain 52 during deflection. Figure 15 As shown, there is a gap 10 between the guide member 4 and the carrier plate 1, which reserves space for the guide member 4 to elastically deform in the Y direction due to the deflection of the sliding bracket 3 during operation. Figure 18 shown.

[0050] The assembly of the lifter device for powering the automobile glass according to the utility model includes: firstly, installing the cable 51 into the drag chain 52, and then installing the first connector 511 and the second connector 512 at both ends of the cable 51 to assemble into a wiring harness assembly 5. Then, the fixed end 521 and the movable end 522 of the drag chain 52 of the wiring harness assembly 5 are respectively installed on the guide 4 and the connecting member 6, and the second connector 512 is installed on the connecting member 6 to assemble into a power supply assembly B, such as Figure 19 Then, the power supply component B is assembled on the carrier plate 1 by screws or clamping, and then the connecting piece 6 on the power supply component B is installed on the sliding bracket 3. At this time, the power supply component B has been assembled on the window lifter, and then the two connectors 511 and 512 of the wiring harness are respectively connected to the glass end and the body end, see Figure 3 , the function of supplying power to the glass can be realized, such as Figure 20 shown.

[0051] During operation, the movement of the drag chain 52 wrapped around the cable 51 is restricted within the guide 4. When the sliding bracket 3 drives the window glass A to move up and down, the moving end 522 of the drag chain 52 moves synchronously with the window glass A. During the entire movement of the drag chain 52 (moving in the Z direction in an arc-shaped trajectory), the drag chain 52 is partially or completely restricted within the flange of the guide 4, and the movement trajectory in the X and Y directions is restricted, reducing the possibility of the mechanism being impacted and making abnormal noises, and providing guidance for the drag chain during the entire movement. In this way, the present invention can be used to transmit current to the window glass without causing the movement trajectory of the wiring harness assembly 5 inside the door to be uncontrolled, and ensure the stability of the power supply and reduce the problem of wiring harness vibration and abnormal noise. Specifically, the present invention uses a modular design and a modular assembly scheme so that the power supply structure of the window lifter can be adapted to different lifters.

[0052] The above are only the preferred embodiments of the present utility model, and are not intended to limit the scope of the present utility model. Various changes can be made to the above embodiments of the present utility model. That is, all simple, equivalent changes and modifications made in accordance with the claims and the content of the specification of the present utility model application fall within the scope of protection of the claims of the present utility model patent. Those not described in detail in the present utility model are all conventional technical contents.
