[0035] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0036] like Figures 1 to 3 As shown, this embodiment provides an electrically controlled dimming power supply mechanism and a dimming device. The dimming device includes an electrically controlled dimming component and an electrically controlled dimming power supply mechanism, which supplies power to the electrically controlled dimming component. The electrically controlled dimming component includes a mounting portion 100, which is movably disposed on a mounting member 200 along a preset direction. Specifically, the mounting portion 100 is slidably disposed on the mounting member 200 via a first slide rail.

[0037] The electronically controlled dimming power supply mechanism includes a wiring harness 1 and a guide assembly 2. One end of the wiring harness 1 is used for electrical connection with the electronically controlled dimming component, and the other end is used for electrical connection with the power supply. The wiring harness 1 includes an installation section 11. The guide assembly 2 includes a guide member 21 and a sliding member 22. The sliding member 22 is slidably connected to the installation part 100 along a first direction, and the sliding member 22 is slidably connected to the guide member 21 along a second direction. The wiring harness 1 is movably disposed on the guide member 21 along the second direction, and the sliding member 22 is connected to the installation section 11. The first direction is perpendicular to a preset direction, the second direction is set at an angle to the first direction, and the second direction is parallel to a preset surface, which is the surface determined by the first direction and the preset direction.

[0038] In this embodiment of the electronically controlled dimming power supply mechanism, when the electronically controlled dimming component moves along a preset direction, the sliding member 22 can slide along the guide member 21 along a second direction. The sliding member 22 is connected to the mounting section 11 of the wire harness 1, thereby driving the wire harness 1 to move along the guide member 21 along the second direction, so as to control the movement direction of the wire harness 1 and reduce the risk of the wire harness 1 getting tangled or interfering with its components. At the same time, the sliding member 22 can also slide relative to the mounting part 100 of the electronically controlled dimming component along a first direction. Therefore, even when the second direction is not parallel to the preset direction, the sliding member 22 can still slide smoothly on the guide member 21 without jamming, which can improve the assembly convenience of the guide member 21 and thus improve the versatility of the electronically controlled dimming power supply mechanism.

[0039] It should be noted that the second direction can be set parallel to the preset direction, or the angle between the second direction and the preset direction can be set to an acute angle.

[0040] When the second direction is parallel to the preset direction, the electronically controlled dimming component moves along the preset direction, and the mounting part 100 drives the sliding member 22 to slide along the second direction on the guide member 21. The sliding member 22 will not slide relative to the mounting part 100 along the first direction.

[0041] When the angle between the second direction and the preset direction is acute, the electronically controlled dimming component moves along the preset direction. The mounting part 100 drives the sliding member 22 to slide along the second direction on the guide member 21. At the same time, the sliding member 22 also slides relative to the mounting part 100 of the electronically controlled dimming component along the first direction, thereby allowing the sliding member 22 to slide smoothly on the guide member 21 without any jamming. By making the angle between the second direction and the preset direction acute, the guide member 21 can avoid other components around it, thus improving the assembly convenience of the guide member 21.

[0042] In this embodiment, the electrically controlled dimming component is electrically controlled dimming glass; further, the electrically controlled dimming glass has a planar structure; further, if the preset direction extends in a straight line, then the preset surface is a plane, and the second direction also extends in a straight line, and the second direction is parallel to the plane. Of course, the electrically controlled dimming glass can also be configured as a curved structure. Specifically, the mounting component 200 has a mounting surface, and the mounting portion 100 of the electrically controlled dimming glass is movably disposed on the mounting surface along the preset direction. The curved structure is convex or concave relative to the mounting surface; further, if the preset direction extends in a curved shape, then the preset surface is a curved surface, and the second direction also extends in a curved shape, and the second direction is parallel to the curved surface.

[0043] Specifically, the electronically controlled dimming glass is the car window glass, which includes door glass and sunroof glass. The mounting part 100 is a glass bracket, and the mounting component 200 is the door frame or body.

[0044] Optionally, the guide member 21 is elongated, and the extension direction of the elongated guide member 21 is the second direction, which can reduce the space occupied by the guide member 21 and improve the assembly convenience of the guide member 21.

[0045] Optionally, the guide member 21 includes a guide groove 211, and the wire harness 1 includes a movable segment 12 located within the guide groove 211. The movable segment 12 is movably disposed within the guide groove 211 along a second direction, thereby controlling the direction of the wire harness 1 through the guide groove 211, which can further reduce the risk of the wire harness 1 becoming tangled or interfering with other components. As an alternative, the movable segment 12 can also be wound around the outside of the guide member 21; in other words, the movable segment 12 is wound around the outside of the guide member 21 in a spiral structure.

[0046] Specifically, the wire harness 1 includes a first end 1a and a second end 1b. The first end 1a is electrically connected to the electronically controlled dimming component, and the second end 1b is electrically connected to the power supply.

[0047] Optionally, the movable segment 12 has a spiral structure and is disposed within the guide groove 211. This not only increases the length of the movable segment 12 but also gives it a certain degree of elasticity in the second direction. When the sliding member 22 slides along the guide member 21 in the second direction with the electronically controlled dimming member, the sliding member 22 can cause the spiral-shaped movable segment 12 to extend and retract in the second direction. This not only improves the smoothness of the wire harness 1's movement in the second direction but also reduces the risk of the wire harness 1 being pulled and damaged. As an alternative, the movable segment 12 can also have an S-shaped structure and be disposed within the guide groove 211. That is, the wire harness 1 is arranged in an S-shaped bend within the guide groove 211.

[0048] Optionally, the guide member 21 is provided with a limiting structure, which can prevent the wire harness 1 located in the guide groove 211 from coming out of the guide groove 211, thereby avoiding wear and other problems caused by the wire harness 1 entering and leaving the guide groove 211, and protecting the wire harness 1.

[0049] Optionally, the limiting structure includes a first limiting part (not shown in the figure), which is located at both ends of the movable segment 12, along with the mounting segment 11. When the sliding member 22 slides along the guide member 21 in the second direction with the electronically controlled dimming member, the end of the movable segment 12 away from the mounting segment 11 can abut against the first limiting part, thereby preventing the movable segment 12 from dislodging from the guide groove 211 in the second direction.

[0050] Optionally, the mounting section 11 is located at the end of the wire harness 1 connected to the electronically controlled dimming component. The limiting structure includes a second limiting part (not shown in the figure). The second limiting part and the first limiting part are respectively located at both ends of the guide member 21 along the second direction. The mounting section 11 can move with the sliding member 22 and abut or separate from the side of the second limiting part facing the first limiting part along the second direction. When the sliding member 22 slides along the guide member 21 along the second direction with the electronically controlled dimming component, when the sliding member 22 slides to the end of the guide member 21 away from the first limiting part, the mounting section 11 can abut against the side of the second limiting part facing the first limiting part to prevent the mounting section 11 from coming out of the guide groove 211, thereby avoiding problems such as friction between the mounting section 11 and the guide member 21 or the mounting section 11 being hooked by the guide member 21, thus protecting the wire harness 1. When the slider 22 slides toward the end of the guide 21 where the first limiting part is provided, the mounting section 11 can also separate from the second limiting part without interfering with the movement of the slider 22 and the wiring harness 1.

[0051] Specifically, the first limiting part is the first groove wall of the guide groove 211 along the second direction. The first groove wall has a through hole. The end of the wire harness 1 used for connecting to the power supply passes through the through hole and exits the guide groove 211 to connect to the power supply. One end of the spiral movable section 12 abuts against the first groove wall, thereby preventing the movable section 12 from coming out of the guide groove 211 along the second direction. In other words, the end of the guide groove 211 with the first limiting part can provide a storage function for the wire harness 1. When the slider 22 slides on the guide 21 along with the electronically controlled dimming component, the slider 22 can cause the spiral movable section 12 to extend and retract along the second direction.

[0052] Furthermore, the second limiting part is the second groove wall on the other side of the guide groove 211 along the second direction, that is, the first groove wall and the second groove wall are arranged opposite to each other along the second direction.

[0053] Optionally, the limiting structure includes a third limiting part, which is located at the opening of the guide groove 211. By providing the third limiting part, the opening size of the guide groove 211 can be reduced, thereby preventing the movable segment 12 from coming out of the opening of the guide groove 211. Specifically, there are two third limiting parts, which are respectively located on the two opening end faces of the guide groove 211.

[0054] Optionally, the slider 22 is provided with a first clamping structure 221, which is located in the guide groove 211. The first clamping structure 221 can clamp or release the wire harness 1, thereby facilitating the assembly and disassembly of the wire harness 1.

[0055] Optionally, the sliding member 22 is provided with a second clamping structure 222. The second clamping structure 222 is located outside the guide groove 211. The second clamping structure 222 can clamp or release the wire harness 1, thereby facilitating the assembly and disassembly of the wire harness 1. At the same time, the direction of the wire harness 1 can be controlled by the second clamping structure 222, which facilitates the assembly of the wire harness 1 and protects the wire harness 1.

[0056] For example, the first clamping structure 221 is a first wire clamp. The second clamping structure 222 is a second wire clamp.

[0057] Optionally, the installation section 11 includes a bending section 111, which is located between the first clamping structure 221 and the second clamping structure 222. The bending section 111 has an arc or curve structure, which can prevent the wire harness 1 from being damaged due to excessive bending and can extend the service life of the wire harness 1.

[0058] Optionally, the electronically controlled dimming power supply mechanism also includes a protective sleeve 3, which is fitted on the outside of the installation section 11. The protective sleeve 3 is connected to the sliding member 22, thereby protecting the wire harness 1 and extending the service life of the wire harness 1.

[0059] Optionally, one of the slider 22 and the mounting portion 100 is provided with a sliding sleeve 223, and the other is provided with a slider 101. The sliding sleeve 223 is slidably fitted onto the outside of the slider 101 along the first direction, which can improve the uniformity of force on the slider 22 and the mounting portion 100, thereby improving the smoothness of the slider 22 sliding along the first direction. Specifically, the sliding sleeve 223 is provided on the slider 22, and the slider 101 is provided on the mounting portion 100. Of course, the sliding sleeve 223 can also be provided on the mounting portion 100, and the slider 101 can be provided on the slider 22.

[0060] Optionally, the slider 22 is provided with grooves 224 on both sides of the slider 22, and the guide 21 is provided with two connecting parts 212. The two connecting parts 212 are slidably provided in the two grooves 224 along the second direction, which can improve the uniformity of force on the slider 22 and the guide 21, and thus improve the smoothness of the slider 22 sliding along the second direction.

[0061] Specifically, two connecting parts 212 are respectively provided on the two open end faces of the guide groove 211. In other words, a track is formed through the opening of the guide groove 211 so that the sliding member 22 is slidably disposed on the guide member 21 along the second direction. It should be noted that the guide member 21 can be integrally formed on the mounting member 200. Of course, the guide member 21 can also be set as a second slide rail, which is fixedly installed on the mounting member 200, and the track groove of the second slide rail is the guide groove 211.

[0062] Optionally, the two connecting parts 212 are the two third limiting parts mentioned above, which can simplify the structure of the guide 21, facilitate processing, and reduce costs.

[0063] Taking the electronically controlled dimming component as electronically controlled dimming glass, specifically the door glass of a car, the working principle of the electronically controlled dimming power supply mechanism in this embodiment is as follows:

[0064] When the door glass is raised to its highest position, the sliding member 22 is located at the end of the guide member 21 where the second limiting part is provided, and at this time the mounting section 11 abuts against the end of the second limiting part facing the first limiting part.

[0065] When the door glass is lowered, the mounting section 11 separates from the second limiting part, and the sliding member 22 slides on the guide member 21 towards the first limiting part. The mounting section 11 of the wiring harness 1 moves along the second direction with the sliding member 22, thereby compressing the spiral movable section 12. One end of the movable section 12 abuts against the first limiting part. When the door glass is raised, the mounting section 11 of the wiring harness 1 moves along the second direction with the sliding member 22, thereby extending the spiral movable section 12. Thus, during the raising and lowering of the door glass, the movement direction of the wiring harness 1 can be controlled, reducing the risk of the wiring harness 1 becoming tangled or interfering with its components.

[0066] When the slider 22 slides on the guide 21, if the second direction is parallel to the preset direction, the slider 22 will not slide relative to the mounting part 100 along the first direction; if the angle between the second direction and the preset direction is an acute angle, the slider 22 will also slide relative to the mounting part 100 of the electronic dimming component along the first direction, thereby enabling the slider 22 to slide smoothly on the guide 21 without jamming, which can improve the assembly convenience of the guide 21 and thus improve the versatility of the electronic dimming power supply mechanism.

[0067] Note that the above description is merely a preferred embodiment of the present invention and the technical principles employed. Those skilled in the art will understand that the present invention is not limited to the specific embodiments described herein, and various obvious changes, readjustments, and substitutions can be made without departing from the scope of protection of the present invention. Therefore, although the present invention has been described in detail through the above embodiments, the present invention is not limited to the above embodiments, and may include many other equivalent embodiments without departing from the concept of the present invention. The scope of the present invention is determined by the scope of the appended claims.
