Description

Technical Field

[0001] The invention relates to the technical field of automobile windows, and in particular to an automobile dimming window lifting device. Background Art

[0002] Automotive dimming glass is an innovative glass technology used in the automotive field. It has functions such as privacy protection, heat insulation and energy saving, and anti-glare. Technically, dimming glass generally uses electrochromic, liquid crystal dimming or suspended particles to achieve dimming effects. With the improvement of people's quality of life, the demand for dimming door glass is showing a growing trend. However, because the car door glass has the characteristics of lifting and lowering, the wiring harness layout of the dimming glass has become a major problem that currently restricts the promotion of dimming glass.

[0003] The current solution has the following difficulties: 1. After the wiring harness on the dimming glass side is led out, it needs to be installed on the lifter slider, which is difficult to assemble. In addition, the lead wire is long, which is easy to interfere with other accessories in the inner cavity during the glass lifting process. 2. Because the glass needs to be raised and lowered, a long section of the wiring harness needs to be reserved to meet the needs of glass lifting and lowering. However, the wiring harness has no fixed fulcrum in the door cavity, which is easy to produce abnormal noise when opening and closing the door, and will affect the glass lifting and lowering, reducing the service life of the wiring harness.

[0004] There are other structural solutions in the prior art to replace the wiring harness solution, but their structures are complex and the cost is relatively high. For example, patent CN116039535A discloses a wiring harness structure, a glass lifting device and a car for a door dimming glass. The wiring harness structure includes an energized rail, the bottom end of which can be conductively connected to the main wiring harness of the door, and the top end of which faces the dimming glass; an energized slider, which is conductive and slidable in the energized rail; a rigid conductive wire group, the top end of which is used to connect to the liquid crystal layer of the dimming glass, and the bottom end of which is used to connect to the energized slider; the glass lifting device includes a glass lifter and a wiring harness structure for controlling the lifting of the dimming glass, and the side wall of the energized rail is fixed to the glass lifter through a connecting structure; the energized slider structure is relatively expensive. Summary of the invention

[0005] In view of the shortcomings of the prior art, the present invention provides a vehicle dimming window lifting device to achieve the purpose of small space occupied by the wiring harness and relatively low cost.

[0006] In order to solve the above technical problems, the technical solution adopted by the present invention is:

[0007] The automobile dimming window lifting device comprises a dimming glass wire harness, a glass bracket, a lifter guide rail and a lifter slider arranged on the lifter guide rail. The dimming glass of the dimming window is arranged on the glass bracket, the glass bracket is connected to the lifter slider, a wire harness guide structure is arranged on the lifter guide rail, the dimming glass wire harness is wound on the wire harness guide structure, a wire harness guide block which can move up and down is arranged on the wire harness guide structure, the wire harness guide block is connected to the lifter slider, and the upper end of the dimming glass wire harness is positioned on the wire harness guide block.

[0008] Further:

[0009] A connecting harness is provided at the lower part of the dimming glass, and the upper end of the dimming glass harness is connected to the connecting harness via a connector.

[0010] The wire harness guiding structure is a wire harness guiding shaft, and the wire harness guiding block is sleeved on the wire harness guiding shaft.

[0011] The dimming glass is provided with a dimming film, one end of the connecting wire harness is inserted into the dimming glass and connected to the dimming film, the glass bracket is provided with a glass end wire harness connector connected to the other end of the connecting wire harness, and the upper end of the dimming glass wire harness is provided with a lifter end wire harness connector that matches the glass end wire harness connector.

[0012] The upper end and the lower end of the wire harness guide shaft are both bent structures, and the upper and lower bent structures are respectively connected to the upper and lower ends of the lifter guide rail.

[0013] The wire harness guide shaft has the same curvature as the lifter guide rail.

[0014] The bottom of the lifter guide rail is provided with a lead-out wire connector for connecting with the lower end of the dimming glass wire harness.

[0015] A lower stopper for limiting the bottom of the winding wire harness is provided at the bottom of the wire harness guide shaft.

[0016] The contact portion between the wire harness guide block and the guide shaft adopts elastic arc surface contact.

[0017] The main part of the dimming glass harness is a spiral harness, which is wound on a harness guide shaft.

[0018] Compared with the prior art, the present invention has the following advantages:

[0019] The automobile dimming window lifting device has a reasonable structural design. The wiring harness is constrained on the guide shaft. When the glass rises, the wiring harness is stretched along the guide block. When the glass falls, the wiring harness is compressed along the wiring harness guide shaft along the guide block. During the process of glass lifting and closing the door, there will be no interference or collision with other accessories, and there will be no abnormal noise.

Preferably, a dimming film is provided in the dimming glass, one end of the connecting harness is inserted into the dimming glass and connected to the dimming film, a glass end harness connector 1.4 connected to the other end of the connecting harness is provided on the glass bracket, and a lifter end harness connector 2.1 matched with the glass end harness connector is provided at the upper end of the dimming glass harness, and the connection operation is simple.

[0032] The wire harness guide structure 2.3 is a wire harness guide shaft, and the wire harness guide shaft has the same curvature as the lifter guide rail; the wire harness guide block is sleeved on the wire harness guide shaft, and the wire harness guide block is a cylindrical structure, and can move up and down along the axial direction of the guide shaft, and the operation is stable and reliable.

[0033] The upper and lower ends of the harness guide shaft are both bent structures, and the upper and lower bent structures are respectively connected to the upper and lower ends of the lifter guide rails, with a simple structure and relatively low cost.

[0034] A lead-out wire connector 2.6 for connecting with the lower end of the dimming glass wire harness is arranged at the bottom of the lifter guide rail, so that the wire harness can be easily connected.

[0035] The contact part between the harness guide block and the guide shaft adopts elastic arc surface contact, which can effectively avoid the jamming phenomenon during operation;

[0036] The main part of the dimming glass harness is a spiral harness, which is wound on the harness guide shaft. The dimming glass harness can be stably and reliably extended and retracted without being tangled. A lower stopper 2.5 is provided at the bottom of the harness guide shaft for limiting the bottom of the wound harness.

[0037] The automobile dimming window lifting device of the present invention has a reasonable structural design. The wiring harness is constrained on the guide shaft. When the glass rises, the wiring harness is stretched along the guide block. When the glass falls, the wiring harness is compressed along the wiring harness guide shaft along the guide block. During the process of glass lifting and closing and door opening, there will be no interference and collision with other accessories and no abnormal noise. The wiring harness occupies a small space and has a relatively low cost.

[0038] Preferred embodiments of the present invention are:

[0039] The device of the present invention includes an arrangement of a wiring harness leading out of the dimming glass end, a glass bracket on which a glass wiring harness connector can be installed, and a wiring harness guide device on a glass lifter slider. The specific connection method is that after the dimming glass connection wiring harness is led out, the wiring harness connector is fixed on the glass lifter slider and connected to the wiring harness device on the lifter. The other end of the wiring harness on the lifter is connected to the vehicle door wiring harness, and the glass dimming function is realized through control by a regional controller.

[0040] One end of the connecting harness 1.3 on the dimming glass is integrated into the dimming glass 1.1 and connected to the dimming diaphragm during glass production. The connecting harness 1.3 is connected to the conversion block and bonded to the lower part of the inner surface of the glass 1.1 with 3M glue. The other end of the connecting harness 1.3 is connected to the glass end harness connector 1.4 and installed on the glass bracket 1.2. The position of the harness is relatively fixed, avoiding abnormal noise problems during the lifting process / opening and closing of the door.

[0041] The wire harness guide structure 2.3 is installed on the glass lifter guide rail 2.8. The curvature of the wire harness guide structure 2.3 is consistent with that of the lifter guide rail 2.8 to ensure smoother operation. The dimming glass harness 2.4 is installed on the wire harness guide structure 2.3. The lower part is connected to the lead-out connector 2.6 and the sheet metal harness through the lower block 2.5. The upper part of the dimming glass harness 2.4 is installed in the wire harness guide block 2.2. The dimming glass harness 2.4 is led out through the wire harness guide block 2.2 and connected to the lifter end harness connector 2.1. The guide block 2.2 uses arc contact inside to effectively avoid jamming during operation. The guide block 2.2 is installed on the glass lifter slider 2.7.

[0043] The wire harness guide shaft has the same curvature as the lifter guide rail and is arranged below the motion envelope of the lifter slider, without occupying additional space in the door cavity.

[0044] The harness guide block uses elastic arc surface contact with the guide shaft to avoid jamming during lifting.

[0045] The connection direction between the harness guide block and the harness is consistent with the running direction of the glass, and the harness adopts an anti-breakage joint at the connection between the harness and the guide device to improve the durability of the harness.

[0046] The interface between the dimming glass lead-out harness and the lifter harness is fixed on the glass bracket, which is convenient for workshop installation. The harness is relatively static from the glass lead-out to the lifter harness guide block and does not change with the glass lifting, effectively improving the stability of the mechanism.

[0047] The wiring harness is constrained on the guide shaft. When the glass rises, the wiring harness is stretched along the guide block. When the glass falls, the wiring harness is compressed along the wiring harness guide shaft along the guide block. During the process of glass lifting and closing the door, it will not interfere with other accessories, collide, or make abnormal noise.
