[0062] Referring to Figure 1, the background art of the embodiments of this application will be briefly described below, using vehicle 100 as an example.

[0063] Figure 1 is an illustrative diagram of a conventional vehicle. As shown in Figure 1, the vehicle 100 includes a vehicle door, which includes a vehicle door glass 110 and a vehicle door glass lifting device 120. The lifting device 120 is typically located inside the door sheet metal of the vehicle door. Optionally, in the automotive field, the lifting device 120 may also be called a window lifter. This is not limited to the present application.

[0064] As shown in Figure 1, the lifting device 120 may include a clamp 121, a slider 122, a slide rail 123, a pull cable 124, a pulley 125, a motor, and a winch 126.

[0065] The clamp 121, also called a fixing clip, is configured to clamp and secure the vehicle door glass 110. Optionally, in the actual construction, one clamp 121 may be used, or two or more clamps 121 may be used. This is not limited to this.

[0066] The slider 122 is connected to the clamp 121 and configured to slide up and down inside the slide rail 123. As shown in Figure 1, the position of slider 122A is the highest position the slider can slide to, and the position of slider 122B is the lowest position the slider can slide to.

[0067] The slide rail 123, also called a track, includes a slider groove. The slider groove is configured to restrict the sliding path of the slider 122. The slide rail 123 typically has a flange, which may be coupled to the slider 122 to form a sliding system. Optionally, the slider groove may be formed by stamping or extrusion, and the cross-section of the slider groove may be, but is not limited to, a "U" shape, a "V" shape, or a "C" shape.

[0068] The pull cable 124 is connected to the slider 122, which is pulled by the action of the pull cable 124 so that it slides up and down inside the slide rail 123.

[0069] The pulley 125 is configured to provide the pull cable 124 with operational guidance and an appropriate swivel radius. Optionally, the pulley 125 may include pulleys 125A and 125B positioned at the upper and lower ends of the slide rail 123, respectively.

[0070] The motor and winch 126 are configured to power the lifting system and move the pull cable 124 by rotating the winch.

[0071] The overall operating principle of the lifting device 120 is as follows: a motor drives and rotates a winch, the winch pulls and moves a pull cable 124, the pull cable 124 creates a linear displacement inside the slide rail 123 using pulleys 125A and 125B to drive a slider 122 to move up and down along the slide rail 123. Since the slider 122 is connected to the vehicle door glass 110 using a clamp 121, in the process of the slider 122 moving up and down, the slider 122 can drive the vehicle door glass 110 to move up and down.

[0072] It is known that in conventional vehicles, the vehicle door glass is not powered. However, with advancements in science and technology, users have higher demands on vehicle door glass, expecting it to perform various functions such as privacy, sunshade, dimming, color adjustment, display, and touch. In order for vehicle door glass to perform the aforementioned functions, it needs to be powered. Therefore, the method of powering vehicle door glass is a technical problem that needs to be solved urgently.

[0073] Based on this, the embodiments of the present application add a drag chain harness and a drag chain harness groove used to house the drag chain harness, based on a conventional slide rail and a conventional slider, and the fixed end of the drag chain harness is electrically connected to a power source and the movable end is electrically connected to the moving device such as a vehicle door glass in order to supply power to the moving device such as a vehicle door glass.

The drag chain harness 240 includes a fixed end 241 electrically connected to a power supply and a movable end 242 electrically connected to a movable device 201, thereby enabling power to be supplied to the movable device 201.

[0081] Furthermore, in this embodiment of the present application, a drag chain harness 240 is used to protect and restrict the internal harness using a drag chain, in order to avoid the problem of low durability of the harness caused by direct use of the harness. The drag chain harness 240 is also positioned in a drag chain harness groove 230, thereby avoiding the problem of the harness becoming entangled, and the drag chain harness groove 230 can provide guidance and restriction to the drag chain harness 240 to prevent problems such as shaking and noise that occur during the operation process of the drag chain harness 240.

[0082] Optionally, the drag chain harness groove 230 may be fixed to the slide rail 210 in multiple ways.

[0083] In one embodiment, the drag chain harness groove 230 may be directly positioned on the slide rail 210. Specifically, the drag chain harness groove 230 may be positioned on the slide rail 210 along the trajectory direction of the slide rail 210, as shown in Figures 2 and 4. Positioning the drag chain harness groove 230 on the slide rail 210 may be understood as the drag chain harness groove 230 and the slide rail 210 being integrally formed.

[0084] The drag chain harness groove 230 of the power supply unit 200 provided in this embodiment of the present application may be located on the slide rail 210. In this way, the integration of the power supply unit 200 is increased, thereby saving space. Furthermore, it can be ensured that the trajectory direction of the drag chain harness groove 230 coincides with the trajectory direction of the slide rail 210, thereby ensuring consistency in the operating paths of the drag chain harness 240 and the slider 220.

This is not limited to this.

[0086] In this embodiment of the present application, the drag chain harness groove 230 may be fixed to the slide rail 210 using a support 231, which means that the drag chain harness groove 230 may be fixed directly based on a conventional slide rail 210 using a support 231, and the conventional slide rail 210 does not need to be modified, thereby reducing the complexity of the manufacturing process.

[0087] In yet another embodiment, the drag chain harness groove 230 may instead be fixed together with the slide rail 210 by adhesive or welding.

[0088] Optionally, the slide rail 210 may include a slider groove 211, and the slider 220 is positioned within the slider groove 211 of the slide rail 210, with the slider groove 211 configured to restrict the sliding path of the slider 220.

[0089] Optionally, the slider groove 211 may be formed by stamping or extrusion, and the cross-section of the slider groove 211 may be U-shaped, V-shaped, or C-shaped, etc., and is not limited thereto. Similarly, the drag chain harness groove 230 may also be formed by stamping or extrusion, and the cross-section of the drag chain harness groove 230 may also be U-shaped, V-shaped, or C-shaped, etc., and is not limited thereto. The cross-sections of the slider groove 211 and the drag chain harness groove 230 may be the same, for example both may be U-shaped, or they may be different, for example one may be U-shaped and the other V-shaped. This is not limited in this application.

[0090] In this embodiment of the present application, the positional assignment of the drag chain harness groove 230 and the slider groove 211 in cross-section is not limited and may be flexibly configured. Optionally, the drag chain harness groove 230 and the slider groove 211 may be arranged along a first direction, or they may be arranged along a second direction, and the first and second directions may form a first angle.

[0091] For example, the first direction may be perpendicular to the track direction of the slide rail 210 and parallel to the plane on which the movable device 201 is located, that is, it may be the x-direction shown in Figure 2, and the second direction may be perpendicular to the track direction of the slide rail 210 and perpendicular to the plane on which the movable device 201 is located, that is, it may be the y-direction shown in Figure 2, and the first angle is 90°.

[0092] In this case, if the drag chain harness groove 230 and the slider groove 211 are arranged along the first direction, the openings of the drag chain harness groove 230 and the slider groove 211 may face the plane on which the moving device 201 is located (as shown in Figures 2, 5, and 6), thereby ensuring consistency in the operating paths of the drag chain harness 240 and the slider 220.

[0093] When the drag chain harness groove 230 and slider groove 211 are arranged along a second direction, the opening of the drag chain harness groove 230 may face the plane on which the movable device 201 is located, or the drag chain harness groove 230 may be located on the side of the slider groove 211 away from the slider groove 211, with the opening of the drag chain harness groove 230 facing the slider groove 211 (as shown in Figure 4). In this way, the integration of the power supply unit is increased, thereby saving space. Furthermore, it can be ensured that the trajectory direction of the drag chain harness groove coincides with the trajectory direction of the slider groove, thereby ensuring consistency in the operating paths of the drag chain harness and the slider. Optionally, in this case, the cross-sections of the drag chain harness groove 230 and slider groove 211 may be in the shape of an inverted "T" or a variation thereof. This is not limited to this.

[0094] Optionally, the power supply unit 200 may further include a limiter 260. See Figures 2 to 6 for details on the limiter 260.

[0095] Optionally, the limiter 260 may be positioned on the slider 220, clamp 250, or moving device 201, and the limiter 260 can move together with the movable end 242 and is configured to limit the protrusion of the movable end 242 on the cross section of the power supply unit 200 so as to be away from the protrusion of the fixed end 241 in order to prevent shaking or abnormal noise caused by the movable end 242 of the drag chain harness 240 during the moving process.

[0096] Optionally, the length of the limiter 260 is not limited to this embodiment of the present application. For example, the length of the limiter 260 may be determined based on the lengths of 3 to 5 sections of the drag chain.

[0097] Optionally, the limiter 260 may include, but is not limited to, one of the following: a baffle plate, a stopper, and an upper reinforcement bar.

[0098] The positional assignment of the fixed end 241 and the movable end 242 in the cross-section is not limited to this embodiment of the present application and may be flexibly set. Optionally, the fixed end 241 and the movable end 242 may be arranged along a third direction, or along a fourth direction, and the third and fourth directions may form a second angle.

[0099] Optionally, the third direction may be perpendicular to the trajectory direction of the slide rail 210 and parallel to the plane on which the moved device 201 is located (i.e., the x-direction described above). When the fixed end 241 and the movable end 242 are arranged along this direction, the orientation of the connecting pins of each section of the drag chain is perpendicular to the plane on which the moved device 201 is located, which can also be understood as the plane formed by the operating path of the drag chain being parallel to the plane on which the moved device 201 is located, as shown in Figure 6. In this case, the drag chain harness groove 230 occupies a relatively small space, which allows for a higher integration of the power supply and saves space.

[0100] Optionally, the fourth direction may be perpendicular to the track direction of the slide rail 210 and perpendicular to the plane on which the moving device 201 is located (i.e., the y-direction). When the fixed end 241 and the movable end 242 are arranged along this direction, the orientation of the connecting pins of each section of the drag chain is parallel to the plane on which the moving device 201 is located, which can also be understood as the plane formed by the operating path of the drag chain being perpendicular to the plane on which the moving device 201 is located, as shown in Figures 2 to 5. In this case, the drag chain harness groove 230 occupies a relatively small space, which allows for a higher integration of the power supply and saves space.

[0101] Based on this, the second included angle could be 90°.

[0102] In actual operation, the third and fourth directions may be the x and y directions, respectively, or may be slightly offset from the x and y directions, and the second included angle may be 90° or close to 90°. This is not limited to the present application.

[0103] In this embodiment of the present application, the movable end 242 can move together with the moving device 201.

[0104] Optionally, the movable end 242 may be configured to be electrically connected to the moving device 201, as can be done in the following two embodiments.

[0105] In one embodiment, the movable end 242 is electrically connected indirectly to the moving device 201 using an extension harness. For example, the movable end 242 may be fixed to a component that can move together with the moving device 201, such as a slider 220 and a clamp 250, and then electrically connected to the moving device 201 using an extension harness. In this embodiment, since the component that can move together with the moving device 201, such as the slider 220 or clamp 250, is stationary relative to the moving device 201, the extension harness is not pulled or tugged during the moving process, thereby ensuring the durability of the extension harness. Alternatively, the harness of a movable end fixed to a component that can move together with the moving device 201, such as the slider 220 or clamp 250, is protected by a drag chain, so that the harness is not directly pulled or tugged during the moving process, and as a result, the durability of the harness is also ensured.

[0106] In another embodiment, the movable end 242 may be directly electrically connected to the moving device 201, i.e., the movable end 242 is directly fixed to the moving device 201. In this embodiment, the harness of the movable end 242 is protected by a drag chain so that the harness is not directly pulled or tugged during the moving process, thereby ensuring the durability of the harness.

[0107] Optionally, the movable end 242 may be fixed to the slider 220, clamp 250, or movable device 201, etc., using a conductive structure. The conductive structure may be a connector or another conductive connection structure, but is not limited to this.

[0108] Optionally, the fixed terminal 241 may be electrically connected directly to the power supply, or it may be electrically connected to the power supply using a harness. This is not limited to this.

[0109] Optionally, the power supply unit 200 may further include a pull cable 270, which is connected to a slider 220 and configured to pull the slider 220 to move it along a slide rail 210; a pulley 280, which includes pulleys 280A and 280B, positioned at both ends of the slide rail 210 and configured to provide the pull cable 270 with operational guidance and a turning radius; and a motor and winch 290, which is configured to provide power to pull and move the pull cable 270 by the rotation of the winch.

[0110] Optionally, the fixed end 241 may be fixed at both ends of the travel stroke, or between the ends of the travel stroke, for example, at the midpoint of the travel stroke or at another position. Figure 7 is an illustrative diagram of the position of the fixed end 241 according to one embodiment of the present application. Figure 7(a) shows the fixed end 241 fixed at the top of the travel stroke, and Figure 7(b) shows the fixed end 241 fixed between the ends of the travel stroke. When the fixed end 241 is fixed between the ends of the travel stroke, as shown in Figure 7, the length of the drag chain harness 240 is significantly reduced, resulting in a reduction in the weight and cost of the drag chain harness 240.

[0111] For example, the fixed end 241 may be fixed to both ends of the drag chain harness groove 230, or to a first position between the ends of the drag chain harness groove 230. When the fixed end 241 is fixed between the ends of the drag chain harness groove 230, the length of the drag chain harness 240 can be reduced, and the weight and cost of the drag chain harness 240 can be reduced compared to when the fixed end 241 is fixed to both ends of the drag chain harness groove 230.

[0112] For example, if the aforementioned motor is positioned between both ends of the slide rail 210, the fixed end 241 may be further fixed to the motor. In this case, the fixed end 241 may be fixed to the motor. Compared to the case where the fixed end 241 is fixed to both ends of the drag chain harness groove 230, the length of the drag chain harness 240 can be reduced, and the weight and cost of the drag chain harness 240 can be reduced.

[0113] The aforementioned positions of the fixed end 242 are merely examples. In actual operation, the specific position to which the fixed end 242 is fixed will be determined based on the actual circumstances. This is not limited in this application, as long as the fixed end 242 is stationary relative to the drag chain harness groove 230.

[0114] The overall operating principle of the power supply unit 200 is as follows: the motor drives and rotates the winch, the winch pulls and moves the pull cable 270, the pull cable 270 creates a linear displacement inside the slide rail 210 using pulleys 280A and 280B to drive the slider 220 up and down along the slide rail 210. The slider 220 is connected to the moving device 201 using a clamp 250 so that the slider 220 can drive the moving device 201 up and down. Similarly, the drag chain harness 240 can transmit power from the power supply to the moving device 201 in order to supply power to the moving device 201.

[0115] Optionally, in this embodiment of the present application, a communication harness may be further introduced into the drag chain harness to facilitate communication between the mobile device 201 and another device.

[0119] Furthermore, in this embodiment of the present application, a drag chain harness is used to protect and restrict the internal harness using a drag chain, in order to avoid the problem of low durability of the harness caused by the direct use of the harness. The drag chain harness is also placed in a drag chain harness groove, which prevents the harness from becoming entangled, and the drag chain harness groove can provide guidance and restriction to the drag chain harness to prevent problems such as shaking and noise that occur during the operation process of the drag chain harness.
