[0032] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the specific technical solutions of this application will be further described in detail below with reference to the accompanying drawings of the embodiments of this application. The following embodiments are used to illustrate this application, but are not intended to limit the scope of this application.
[0033] In the embodiments of this application, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of the embodiments of this application, unless otherwise stated, "multiple" means two or more.
[0034] Furthermore, in the embodiments of this application, directional terms such as "upper," "lower," "left," and "right" are defined relative to the positions in which the components are schematically placed in the accompanying drawings. It should be understood that these directional terms are relative concepts, used for relative description and clarification, and can change accordingly depending on the position of the components in the accompanying drawings.
[0035] In the embodiments of this application, unless otherwise explicitly specified and limited, the term "connection" should be interpreted broadly. For example, "connection" can mean a fixed connection, a detachable connection, or an integral part; it can mean a direct connection or an indirect connection through an intermediate medium.
[0036] In embodiments of this application, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitation, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes that element.
[0037] In the embodiments of this application, the terms "exemplary" or "for example" are used to indicate that something is an example, illustration, or description. Any embodiment or design that is described as "exemplary" or "for example" in the embodiments of this application should not be construed as being more preferred or advantageous than other embodiments or design. Specifically, the use of the terms "exemplary" or "for example" is intended to present the relevant concepts in a specific manner.
[0038] This application provides a vehicle embodiment. It should be noted that the vehicle in this application can refer to large vehicles, small vehicles, special-purpose vehicles, etc. For example, according to vehicle type, the vehicle in this application can be a sedan, an off-road vehicle, a multi-purpose vehicle (MPV), or other types of vehicles. For a vehicle, there are windows, and some windows can be tinted glass. Tinted glass can undergo reversible optical property changes (such as color and transparency) under the action of an applied voltage. By changing the color of the tinted glass, privacy can be provided to passengers. Furthermore, tinted glass can also change its color according to different sunlight, providing comfort to passengers. Tinted glass requires an external power source to change its color, and it also needs to meet the requirements of raising and lowering. Therefore, a power supply line is needed to provide uninterrupted power to the tinted glass. However, the power supply line is prone to interference and friction with surrounding components when the tinted glass rises or falls.
[0039] Based on this, this application provides a vehicle window glass power supply device 20. The vehicle window glass power supply device 20 includes a drive component 2, a lifting component 3, a first conductive wire 4, and a second conductive wire 5. The lifting component 3 includes a lifting slide rail 31 and a slider 32. The lifting slide rail 31 can be installed on the vehicle door and is located between the outer panel of the vehicle door and the interior panel of the vehicle door. The lifting slide rail 31 extends in the vertical direction. The slider 32 is movably disposed on the lifting slide rail 31 and is used to fix the vehicle window glass. The vehicle window glass 10 is fixed above the slider 32. When the slider 32 rises or falls along the lifting slide rail 31, it can synchronously drive the vehicle window glass 10 to rise or fall synchronously, for opening or closing the vehicle window glass 10.
[0040] The first conductive wire 4 has a first end and a second end, which are the two ends along the length of the first conductive wire 4, respectively. The second conductive wire 5 has a third end and a fourth end, which are the two ends along the length of the second conductive wire 5, respectively. The first conductive wire 4 and the second conductive wire 5 can function not only as ropes but also as conductors of electricity. They can not only pull the car window glass 10 up or down but also transmit current.
[0041] The first end of the first conductive wire 4 is connected to the slider 32 via the upper end of the lifting slide rail 31. For example, the upper end of the lifting slide rail 31 may be provided with a pulley, and the first end of the first conductive wire 4 may pass around the pulley and be connected to the slider 32. The third end of the second conductive wire 5 is connected to the slider 32 via the lower end of the lifting slide rail 31. For example, the lower end of the lifting slide rail 31 may be provided with a pulley, and the third end of the second conductive wire 5 may pass around the pulley and be connected to the slider 32.
[0042] Furthermore, the first end of the first conductive wire 4 and the third end of the second conductive wire 5 are both electrically connected to the car window glass 10, and the second end of the first conductive wire 4 and the fourth end of the second conductive wire 5 are both electrically connected to the external circuit, so that the current of the external circuit can be transmitted to the car window glass 10 through the first conductive wire 4 and the second conductive wire 5.
[0043] By setting up the drive component 2, the lifting component 3, the first conductive line 4 and the second conductive line 5, the window glass 10 can not only be driven to rise or fall, but also power the window glass 10 without the need for additional power supply lines. This simplifies the structure of the window glass power supply device 20 and avoids interference or friction with surrounding components.
[0044] In some specific embodiments of this application, the drive assembly 2 may include a drive motor 21 and a winding reel 22. Both the drive motor 21 and the winding reel 22 may be provided. The second end of the first conductive wire 4 and the fourth end of the second conductive wire 5 may be wound around the outer periphery of the same winding reel 22. The first conductive wire 4 and the second conductive wire 5 are wound in a clockwise or counterclockwise direction, respectively. The drive motor 21 is connected to the winding reel 22 for driving the winding reel 22 to rotate in a clockwise or counterclockwise direction, thereby causing the first conductive wire 4 to release and the second conductive wire 5 to tighten, or the first conductive wire 4 to tighten and the second conductive wire 5 to release, so that the vehicle window glass 10 rises or falls.
[0045] Two drive motors 21 and two reels 22 can be provided. The second end of the first conductive wire 4 can be wound around the outer periphery of one of the reels 22, and one drive motor 21 is driven by one reel 22. The fourth end of the second conductive wire 5 can be wound around the outer periphery of the other reel 22, and the other drive motor 21 is driven by the other reel 22. By driving one reel 22 to rotate clockwise or counterclockwise with one drive motor 21, the first conductive wire 4 is released or tightened. By driving the other reel 22 to rotate counterclockwise or clockwise with the other drive motor 21, the second conductive wire 5 is tightened or released, so that the window glass 10 can rise or fall.
[0046] The vehicle window glass power supply device 20 provided in this application embodiment, by setting up a drive component 2, a lifting component 3, a first conductive wire 4 and a second conductive wire 5, can not only drive the vehicle window glass 10 to rise or fall, but also supply power to the vehicle window glass 10 without the need for additional power supply lines, thereby simplifying the structure of the vehicle window glass power supply device 20 and avoiding interference or friction with surrounding components.
[0047] Reference Figures 2-3 In one possible implementation of this application, the drive assembly 2 includes a drive motor 21 and a winding reel 22. The second end of the first conductive wire 4 and the fourth end of the second conductive wire 5 are wound on the winding reel 22 in a clockwise or counterclockwise direction, respectively. The second end of the first conductive wire 4 and the fourth end of the second conductive wire 5 are both fixedly connected to the winding reel 22. The drive motor 21 has a motor shaft 211, which is connected to the winding reel 22 for transmission to drive the winding reel 22 to rotate.
[0048] When the car window glass 10 needs to be lowered, the drive motor 21 drives the winding wheel 22 to rotate clockwise or counterclockwise through the motor shaft 211 to release the first conductive wire 4 and tighten the second conductive wire 5. The second conductive wire 5 can pull the slider 32 down, and at the same time drive the car window glass 10 down.
[0049] When the car window 10 needs to be raised, the drive motor 21 drives the winding wheel 22 to rotate counterclockwise or clockwise through the motor shaft 211 to tighten the first conductive wire 4 and release the second conductive wire 5. The first conductive wire 4 can pull the slider 32 to rise, and at the same time drive the car window 10 to rise.
[0050] For example, the center of the winding reel 22 has a through hole 226, and the motor shaft 211 extends into the through hole 226 and is fixedly connected to the winding reel 22. When the motor shaft 211 of the drive motor 21 rotates, it can drive the winding reel 22 to rotate synchronously.
[0051] Reference Figures 2-3In one possible implementation of this application, the outer periphery of the winding reel 22 has a plurality of sequentially surrounding grooves 223, which are a continuous groove. The axial ends of the winding reel 22 are a fifth end 221 and a sixth end 222, respectively. The second end of the first conductive wire 4 is wound around the groove 223 along the fifth end 221, and the fourth end of the second conductive wire 5 is wound around the groove 223 along the sixth end 222. The groove 223 can limit the winding or unwinding of the first conductive wire 4 and the second conductive wire 5.
[0052] The first conductive wire 4 and the second conductive wire 5 are wound from both ends of the axial direction of the winding wheel 22 toward the center of the winding wheel 22, and the winding directions of the first conductive wire 4 and the second conductive wire 5 in the wire groove 223 are opposite, so as to facilitate the tightening or unwinding of the first conductive wire 4 and the second conductive wire 5 and avoid interference when the first conductive wire 4 and the second conductive wire 5 are tightened or unwinding.
[0053] Reference Figures 1-2 In one possible implementation of this application, the drive assembly 2 further includes a winding reel housing 23, which is disposed opposite to the winding reel 22 and is connected to the drive motor 21 for wrapping the winding reel 22.
[0054] The reel housing 23 has a first conductive slide rail 231 and a second conductive slide rail 232 arranged radially at intervals. Both the first conductive slide rail 231 and the second conductive slide rail 232 are electrically connected to an external circuit. The second end of the first conductive wire 4 is movably disposed in the first conductive slide rail 231, and the fourth end of the second conductive wire 5 is movably disposed in the second conductive slide rail 232.
[0055] For example, both the second conductive slide rail 232 and the second conductive slide rail 232 are arc-shaped and arranged circumferentially around the winding reel housing 23.
[0056] When the winding reel 22 rotates, it synchronously drives the second end of the first conductive wire 4 and the fourth end of the second conductive wire 5 to move synchronously. The second end of the first conductive wire 4 is movably disposed in the first conductive slide rail 231, and the fourth end of the second conductive wire 5 is movably disposed in the second conductive slide rail 232, so that the second end of the first conductive wire 4 and the fourth end of the second conductive wire 5 are always electrically connected to the external circuit.
[0057] Reference Figures 2-5In one possible implementation of this application, the second end of the first conductive wire 4 has a first terminal post 41, which is movably disposed on the first conductive slide rail 231; the fourth end of the second conductive wire 5 has a second terminal post 51, which is movably disposed on the second conductive slide rail 232, thereby improving the compatibility between the first conductive wire 4 and the first conductive slide rail 231, as well as the compatibility between the second conductive wire 5 and the second conductive slide rail 232.
[0058] For example, the end of the first terminal post 41 is a hemispherical shape adapted to the first conductive slide rail 231; the end of the second terminal post 51 is also a hemispherical shape adapted to the second conductive slide rail 232, which can increase the contact area between the first terminal post 41 and the first conductive slide rail 231, and between the second terminal post 51 and the second conductive slide rail 232, to avoid electrical connection failure.
[0059] Reference Figures 4-5 In one possible implementation of this application, the first contact post 41 includes a carbon brush, which can conduct current between the rotating part and the stationary part, and can transmit current from the first conductive slide rail 231 to the first conductive wire 4; moreover, the carbon brush is made of soft material, which can achieve good contact without damaging the first conductive slide rail 231.
[0060] The second contact post 51 includes a carbon brush, which can conduct current between the rotating part and the stationary part, and can transmit current from the second conductive slide rail 232 to the second conductive wire 5; moreover, the carbon brush is made of soft material, which can achieve good contact without damaging the second conductive slide rail 232.
[0061] Reference Figures 2-5 In one possible implementation of this application, the outer periphery of the winding reel 22 has a plurality of sequentially surrounding grooves 223. The axial ends of the winding reel 22 are a fifth end 221 and a sixth end 222, respectively. The second end of the first conductive wire 4 is wound around the groove 223 along the fifth end 221, and the fourth end of the second conductive wire 5 is wound around the groove 223 along the sixth end 222. The winding reel 22 has a first limiting channel 224 and a second limiting channel 225. The first terminal post 41 is adapted to be fixed in the first limiting channel 224 through the fifth end 221, and the second terminal post 51 is adapted to be fixed in the second limiting channel 225 through the sixth end 222, which can avoid interference between the first terminal post 41 and the second terminal post 51 in position.
[0062] Reference Figures 1-4In one possible implementation of this application, the reel housing 23 has a first plug-in terminal 233, which includes a first pin and a second pin. The first pin is electrically connected to the first conductive slide rail 231, and the second pin is electrically connected to the second conductive slide rail 232. The first plug-in terminal 233 is electrically connected to an external circuit, which makes the method of electrically connecting the first conductive slide rail 231 and the second conductive slide rail 232 to the external circuit simple and reliable.
[0063] Reference Figure 1 , Figures 6-7 In one possible implementation of this application, the vehicle window glass 10 includes a second plug-in terminal 1, and the ends of the first conductive wire 4 and the second conductive wire 5 facing the vehicle window glass 10 have a third plug-in terminal 6. The second plug-in terminal 1 is plugged into the third plug-in terminal 6 to realize the transmission of current from the first conductive wire 4 and the second conductive wire 5 to the vehicle window glass 10.

[0065] The vehicle provided in this application embodiment includes the window glass power supply device 20 provided in any of the above-mentioned embodiments. Therefore, it has the same technical effect, that is, without the need to set up an additional power supply line, it can not only drive the window glass 10 to rise or fall, but also supply power to the window glass 10, thereby simplifying the structure of the window glass power supply device 20 and avoiding interference or friction with surrounding components.

The above are merely preferred embodiments of this application and do not limit the patent scope of this application.
