Description

Technical Field

[0001] The invention relates to the technical field of automobile equipment, and in particular to a power supply structure for a window lifting glass. Background Art

[0002] As an indispensable part of the car, glass can block solar energy, sound, dim, provide passengers with a comfortable riding environment and protect their privacy, heat, defrost and defog to provide a view, use solar power to save car energy, integrate display functions to provide information to customers, and even add sensors to provide security for vehicle safety; however, these functions require power supply or power extraction, which requires reliable conductive lines or wire devices. However, there are few good solutions on the market today that can meet the requirements of the OEM to power the glass. The installation positions of automobile glass are generally divided into front windshield, rear windshield, four-door fixed corner windows, front and rear fixed side windows, four-door door glass, and sunroof; among them, the front windshield, rear windshield, four-door fixed corner windows, and front and rear fixed side windows are generally fixed glass with mature power supply assembly solutions, while the circuit design of four-door glass, sliding windows and sliding sunroof is relatively difficult due to their relative movement characteristics.

[0003] The four-door glass includes a glass rail and a glass sliding bracket arranged on the glass rail. The glass sliding bracket slides up and down through the glass rail, and the door glass is arranged on the glass sliding bracket through the glass bracket. Most of the power supply solutions for movable glass are to directly wrap a layer of foam outside the wire to prevent scratches and abnormal noises. In this way, the wire will still make abnormal noises and there is a risk of being entangled with other parts and being hung up. Long-term use will cause the foam to be rubbed off, resulting in increased abnormal noises and even leakage. Therefore, new solutions are needed to solve the above problems. Summary of the invention

DETAILED DESCRIPTION

[0022] The present invention will be further described in detail below in conjunction with the accompanying drawings.

[0023] like Figure 1 and Figure 2 As shown, a window lifting glass power supply structure in this specific embodiment includes a glass guide rail 1 and a glass sliding bracket 7 slidably connected to the glass guide rail 1, a door glass bracket 8 is fixedly installed on the glass sliding bracket 7, and a door glass 9 is fixedly installed on the door glass bracket 8. A bar tooth 2 is vertically installed in the length direction of the glass guide rail 1, a sliding end 6 that can slide horizontally along the glass sliding bracket is installed on the glass sliding bracket 7, a gear frame 3 is installed on the sliding end, and the gear frame 3 is slidably connected to the bar tooth 2, a rotatable winding shaft 14 is provided on the gear frame 3, and the winding shaft axis is perpendicular to the side of the glass sliding bracket 7, and a winding shaft meshing with the bar tooth 2 is installed on the winding shaft 14 The gear 15 drives the winding shaft to rotate with the lifting of the gear frame; a bearing 13 is provided at the sliding end 6, and the winding shaft is connected to the sliding end 6 through the bearing, and the outer ring of the bearing 13 extends toward the sliding end relative to the end of the winding shaft to form an extension portion, and the extension portion is provided with an upward wire hole; a wire 5 is wound on the winding shaft 14, and the lower end of the wire is fixedly installed with the lower end of the bar tooth 2, and the end of the lower end of the wire 5 is connected to the power supply cable, and the winding shaft 14 has a radial threading channel and an axial threading channel that are interconnected. The upper end of the wire 5 passes through the radial threading channel and the axial threading channel in turn, and then passes through the end face of the winding shaft close to the door glass 9, and then passes through the wire hole of the extension portion upward and is then sealed and connected to the wiring position on the door glass.

[0024] In the present invention, a bearing 13 is provided on the sliding end 6, and the winding shaft 14 is connected to the sliding end 6 through the bearing. The outer ring of the bearing 13 extends toward the sliding end relative to the end of the winding shaft to form an extension portion, and an upward wire hole is provided on the extension portion. The upper end of the wire 5 passes through the radial threading channel and the axial threading channel in turn, and then passes through the end face of the winding shaft close to the door glass, and then passes upward from the wire hole of the extension portion and is sealed and connected with the wiring position on the door glass 9. In this way, the rotation of the winding shaft 14 will not drive the upper end of the wire 5 to move, so that the upper end of the wire is relatively stationary, thereby avoiding entanglement, scratching, and abnormal noise. The wire 5 is wound around the circumferential surface of the winding shaft, so that the wire 5 can be wound or unfolded as the door glass is raised or lowered. When the door glass drops to the lowest point, the number of turns of the wire 5 on the winding shaft is the largest. Conversely, as the door glass rises, the number of turns of the wire on the winding shaft decreases accordingly, so as to keep the wire under tension at all times during the rising or falling of the door glass, and prevent the wire from being scratched, making abnormal noises, or being entangled with other parts, causing leakage, and other problems when the door glass is raised or lowered.

[0025] See also Figure 1 and Figure 2In the specific implementation, in order to further constrain the trajectory of the wire 5, maintain the neatness of the wire arrangement, and avoid the wire being under tension for a long time, thereby reducing the service life of the wire. A wire pressing shaft 16 can be installed horizontally and rotatably between the winding shaft 14 and the bar-shaped tooth 2 on the gear frame 3, and a wire pressing shaft gear 17 corresponding to and meshing with the winding shaft gear 15 and the bar-shaped tooth 2 rack is fixedly installed on the wire pressing shaft 16 to drive the wire pressing shaft and the winding shaft to rotate with the gear frame 3; a wire accommodating groove is opened on the bar-shaped tooth 2 along the length direction of the bar-shaped tooth, and an annular wire pressing groove corresponding to the wire accommodating groove is opened on the circumferential surface of the wire pressing shaft 16. The wire 5 coming from the winding shaft passes through the annular wire pressing groove and then enters the wire accommodating groove, so that the wire 5 is embedded in the wire accommodating groove through the guidance of the annular wire pressing groove.

[0026] In this way, the wires unrolled on the winding shaft can always be located in the wire accommodating groove. When the door glass 9 descends, the glass sliding bracket 7 drives the gear frame 3 to move downward along the bar teeth 2. Since the winding shaft gear 15 is meshed with the bar teeth 2, during the downward movement, the winding shaft gear 15 drives the winding shaft 14 to rotate, and the wires 5 located in the wire accommodating groove are continuously brought out and wound on the circumferential surface of the winding shaft 14. The number of winding turns gradually increases as the door glass descends, and the rotation stops as the door glass 9 stops descending. When the door glass rises, the direction of rotation of the winding shaft is just opposite to the direction of rotation of the winding shaft when the door glass descends, so as to gradually unroll the wires 5 wound on the winding shaft. The unrolled wires are continuously embedded in the wire accommodating groove under the guidance of the wire pressing groove, so as to realize the regular placement of the wires, keep the wires 5 under the action of tension all the time during the rising or falling process of the door glass 9, and prevent the wires from scratching, making abnormal sounds, or winding around other parts, or causing leakage when the door glass 9 is raised or lowered.

[0027] In specific implementation, in order to better guide the wire 5 into the wire accommodating groove, the cross-sectional shapes of the wire accommodating groove and the annular wire pressing groove are semicircular respectively, and the radius of the semicircle corresponds to the radius of the wire. The wire accommodating groove and the annular wire pressing groove can be closed to form a closed circle.

[0028] In specific implementation, in order to prevent the wire from scratching and making abnormal noises between the inner side of the gear frame when the winding shaft 14 rotates, the stability of the gear transmission between the winding shaft and the wire pressing shaft can be increased. The bar-shaped teeth 2 are composed of two left and right teeth, the wire accommodating groove is opened in the middle of the two bar-shaped teeth, the wire pressing shaft gears 17 are two corresponding to the number of bar-shaped teeth 2 and meshing with each other, and the winding shaft gears 15 are two corresponding to and meshing with the two wire pressing shaft gears 17; the annular wire pressing groove is opened on the circumferential surface of the wire pressing shaft between the two wire pressing shaft gears; the wire is wound on the circumferential surface of the wire pressing shaft between the two winding shaft gears.

[0029] See also Figure 2In order to prevent rainwater from penetrating into the winding shaft and causing a short circuit, an insulating bearing end cap 12 is provided at the end of the bearing 13 facing the sliding end 6 to cover the corresponding bearing end and achieve insulation.

[0030] See also Figure 2 In a specific implementation, a waterproof gasket 11 is provided between the insulating bearing end cover 12 and the sliding end head 6 .

[0031] In a specific implementation, in order to improve the connection stability and occupy a smaller connection space, the upper end of the wire 5 is connected to the electric tongue piece provided at the wiring position of the door glass 9 .

[0032] In a specific implementation, in order to prevent the wire from contacting water during the lifting and lowering of the door glass 9 and to prevent a short circuit, the upper end of the wire 5 may be sealed to form a sealed end 10 .

[0033] In specific implementation, in order to facilitate installation and maintenance, a power interface is provided at the lower end of the wire 5, and the power supply cable is connected to the power interface by providing a power connector adapted to the power interface, and a sealed end is provided at the connection between the power interface and the power connector.

[0034] In a specific implementation, in order to further improve the insulation effect, the winding shaft, the winding shaft gear, the wire pressing shaft, the wire pressing shaft gear, and the bar teeth are all made of plastic.

[0035] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention rather than to limit it. Although the present invention has been described with reference to the preferred embodiments of the present invention, it should be understood by those skilled in the art that various changes may be made in form and details without departing from the spirit and scope of the present invention as defined in the appended claims.
