[0039] 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.
[0040] like Figures 1 to 4 As shown, this embodiment provides a telescopic power supply mechanism and an electrically controlled dimming device. The electrically controlled dimming device includes an electrically controlled dimming component and a telescopic 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. Exemplarily, the mounting portion 100 is slidably disposed on the mounting member 200 via a first slide rail.
[0041] The telescopic power supply mechanism includes a wiring harness 1 and a telescopic member 2. One end of the wiring harness 1 is used to be electrically connected to the electronically controlled dimming component, and the other end is used to be electrically connected to the power supply. The wiring harness 1 is movably disposed on the telescopic member 2 along the axial direction. The telescopic member 2 includes a first end 21 and a second end 22 disposed opposite to each other along its axial direction. The first end 21 is used to be rotatably connected to the mounting part 100, and the second end 22 is used to be rotatably connected to the mounting part 200. When the mounting part 100 moves, the telescopic member 2 can extend and retract along its axial direction.
[0042] In this embodiment, the telescopic power supply mechanism allows the telescopic member 2 to extend and retract along its axial direction when the mounting part 100 moves, thereby controlling the movement direction of the wire harness 1 and reducing the risk of the wire harness 1 becoming tangled or interfering with its components. At the same time, by simply rotatably connecting the first end 21 of the telescopic member 2 to the mounting part 100 and the second end 22 to the mounting part 200, the telescopic member 2 can be linked with the electronically controlled dimming component. This not only has a simple structure and is easy to assemble, but also has strong versatility.
[0043] In this embodiment, the electrically controlled dimming component is electrically controlled dimming glass. Specifically, the electrically controlled dimming glass is the window glass of an automobile, including door glass and sunroof glass. The mounting part 100 is a glass bracket, and the mounting component 200 is a door frame or body.
[0044] Optionally, the wire harness 1 includes a movable segment 11, which is spirally wound around the outside of the telescopic member 2. This not only increases the length of the movable segment 11 but also gives it a certain degree of elasticity in the axial direction of the telescopic member 2. When the telescopic member 2 extends or retracts, the spirally structured movable segment 11 can extend or retract along the axial direction of the telescopic member 2, which not only improves the smoothness of the wire harness 1's movement along the axial direction of the telescopic member 2 but also reduces the risk of the wire harness 1 being damaged by pulling. As an alternative, the telescopic member 2 has a receiving space, and the movable segment 11, which is spirally structured, is disposed within the receiving space. Exemplarily, the telescopic member 2 has a hollow structure, that is, the telescopic member 2 has an inner cavity, which is the aforementioned receiving space.
[0045] In this embodiment, the telescopic component 2 is a telescopic rod, which has a simple structure, high reliability, and low cost. As an alternative, the telescopic component 2 can also be an elastic rope. Under the gravity of the wire harness 1 wound around the elastic rope, the elastic rope will not undergo elastic deformation; when subjected to the tension of the mounting part 100, the elastic rope can undergo elastic deformation.
[0046] Optionally, the telescopic power supply mechanism further includes a rotating seat 3, which is rotatably mounted on the mounting part 200 around a first axis, and a second end 22 is rotatably mounted on the rotating seat 3 around a second axis; the second axis is perpendicular to the first axis; the first end 21 is rotatably mounted on the mounting part 100 around a third axis; the third axis is parallel to the first axis.
[0047] For ease of description, the direction of movement of the mounting part 100 on the mounting member 200 is referred to as the preset direction. When the preset direction is perpendicular to the first axis, that is, when the preset direction extends in a straight line, the second end 22 will not rotate around the second axis when the mounting part 100 moves on the mounting member 200 along the preset direction. When the preset direction extends in a curved shape, such as when the curve is convex or concave in a direction parallel to the first axis, the second end 22 can rotate around the second axis when the mounting part 100 moves on the mounting member 200 along the preset direction. This avoids the telescopic member 2 being damaged by a force in a direction parallel to the first axis and improves the versatility of the telescopic power supply mechanism.
[0048] Specifically, the rotating seat 3 is rotatably connected to the mounting part 200 via a first pin 41, the axis of which is the first axis. The second end 22 is rotatably connected to the rotating seat 3 via a second pin 42, the axis of which is the second axis. The first end 21 is rotatably connected to the mounting part 100 via a third pin 43, the axis of which is the third axis.
[0049] Optionally, the first end 21 is provided with a first limiting part (not shown in the figure), and the movable section 11 can abut against the first limiting part along the axial direction of the telescopic member 2. This not only prevents the movable section 11 from moving to the connection between the first end 21 and the mounting part 100, thus preventing the relative rotation between the first end 21 and the mounting part 100 from affecting the relative rotation, but also prevents the relative rotation between the first end 21 and the mounting part 100 from causing wear to the wire harness 1, thereby protecting the wire harness 1.
[0050] Optionally, the second end 22 is provided with a second limiting part (not shown in the figure), and the movable section 11 can abut against the second limiting part along the axial direction of the telescopic member 2. This not only prevents the movable section 11 from moving to the connection point between the second end 22 and the mounting member 200, thus affecting the relative rotation between the second end 22 and the mounting member 200, but also prevents the relative rotation between the second end 22 and the mounting member 200 from causing wear to the wire harness 1, thus protecting the wire harness 1.
[0051] Optionally, the telescopic power supply mechanism also includes a first connector (not shown in the figure). The first connector is located at the first end 21 and is fixedly connected to the wire harness 1. This allows one end of the movable section 11 to be fixed to the first end 21. When the telescopic member 2 moves and extends with the electronically controlled dimming component, the risk of the wire harness 1 being pulled and damaged due to the movement of the movable section 11 can be reduced.
[0052] Optionally, the telescopic power supply mechanism also includes a second connector (not shown in the figure). The second connector is located at the second end 22 and is fixedly connected to the wire harness 1. This allows the other end of the movable section 11 to be fixed at the second end 22. When the telescopic member 2 extends and retracts with the movement of the electronically controlled dimming component, the risk of the wire harness 1 being pulled and damaged due to the movement of the movable section 11 can be reduced.
[0053] Optionally, the first connector can clamp or release the wire harness 1, thereby facilitating not only the assembly and disassembly of the wire harness 1, but also adjusting the tightness of the wire harness 1 located between the electronically controlled dimming component and the first connector by holding the wire harness 1 at different positions, thus reducing the risk of damage to the wire harness 1 from pulling. For example, the first connector is a wire clamp.
[0054] Optionally, the second connector can clamp or release the wire harness 1, thereby facilitating not only the assembly and disassembly of the wire harness 1, but also adjusting the tightness of the wire harness 1 located between the power supply and the second connector by holding the wire harness 1 at different positions, reducing the risk of damage to the wire harness 1 from pulling. For example, the second connector is a wire clamp.
[0055] Optionally, the first connector is adjustable along the axial position of the telescopic member 2 at the first end 21, thereby facilitating the adjustment of the position of the first connector to allow it to avoid other components around it, thus improving the versatility of the telescopic power supply mechanism.
[0056] Optionally, the second connector is adjustablely positioned at the second end 22 along the axial direction of the telescopic member 2, thereby facilitating the adjustment of the position of the second connector to allow it to avoid other components around it, thus improving the versatility of the telescopic power supply mechanism.
[0057] Optionally, the first connector is rotatably disposed at the first end 21, and a first locking component is provided between the first connector and the first end 21. The first locking component can lock or unlock the first connector and the first end 21, thereby facilitating the adjustment of the direction of the wire harness 1 connected to the first connector by rotating the first connector, avoiding excessive bending of the wire harness 1, and improving the service life and reliability of the wire harness 1.
[0058] Exemplarily, the first locking assembly includes a first rotating shaft and a first nut. The first end 21 of the telescopic member 2 has a first through hole. One end of the first rotating shaft is connected to the first connecting member, and the other end of the first rotating shaft passes through the first through hole and is threadedly connected to the first nut. By pressing the first connecting member against the telescopic member 2 and tightening the first nut, the first connecting member and the first end 21 of the telescopic member 2 can be locked. Loosening the first nut unlocks the first connecting member and the first end 21 of the telescopic member 2. Then, rotating the first connecting member allows the first rotating shaft to rotate within the first through hole, thereby adjusting the direction of the wire harness 1 connected to the first connecting member. The structure is simple and easy to operate.
[0059] Furthermore, multiple first through holes are provided, and the multiple first through holes are spaced apart along the axial direction of the telescopic member 2, so that the first rotating shaft can be inserted into different first through holes to adjust the position of the first connecting member along the axial direction of the telescopic member 2.
[0060] Optionally, the second connector is rotatably disposed at the second end 22, and a second locking component is provided between the second connector and the second end 22. The second locking component can lock or unlock the second connector and the second end 22, thereby facilitating the adjustment of the direction of the wire harness 1 connected to the second connector by rotating the first connector, avoiding excessive bending of the wire harness 1, and improving the service life and reliability of the wire harness 1.
[0061] Exemplarily, the second locking assembly includes a second rotating shaft and a second nut. The second end 22 of the telescopic member 2 has a second through hole. One end of the second rotating shaft is connected to the second connecting member, and the other end of the second rotating shaft passes through the second through hole and is threadedly connected to the second nut. By pressing the second connecting member against the telescopic member 2 and tightening the second nut, the second connecting member and the second end 22 of the telescopic member 2 can be locked. Loosening the second nut unlocks the second connecting member and the second end 22 of the telescopic member 2. Then, rotating the second connecting member allows the second rotating shaft to rotate within the second through hole, thereby adjusting the direction of the wire harness 1 connected to the second connecting member. The structure is simple and easy to operate.
[0062] Furthermore, multiple second through holes are provided, and the multiple second through holes are spaced apart along the axial direction of the telescopic member 2, so that the second rotating shaft can be inserted into different second through holes to adjust the position of the second connecting member along the axial direction of the telescopic member 2.
[0063] Taking the electronically controlled dimming component as electronically controlled dimming glass, specifically a car door glass, the working principle of the telescopic power supply mechanism in this embodiment is as follows:
[0064] For ease of description, such as Figure 1 As shown, when the door glass is raised to the highest position, the position of the mounting part 100 is recorded as the first position 101; when the door glass is lowered to the lowest position, the position of the mounting part 100 is recorded as the second position 102; and when the door glass is between the highest and lowest positions, the position of the mounting part 100 is recorded as the third position 103.
[0065] When the mounting part 100 is in the first position 101 or the second position 102, the telescopic member 2 extends, and the movable section 11, which is spirally wound around the outside of the telescopic member 2, also extends. When the mounting part 100 is in the third position 103, the telescopic member 2 retracts, and the movable section 11, which is spirally wound around the outside of the telescopic member 2, also retracts.
[0066] When the car door window is raised or lowered, the telescopic component 2 can extend or retract along its axis, thereby controlling the movement direction of the wiring harness 1, so as to reduce the risk of the wiring harness 1 getting tangled or interfering with its components.
[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.
