[0062] Referring to FIG. 1, the following uses a vehicle 100 as an example to briefly describe the background technology in the embodiments of the present application.

[0063] 1 is an exemplary diagram of a conventional vehicle. As shown in FIG. 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 usually disposed on the inner side of the door sheet metal of the vehicle door. Optionally, in the vehicle field, the lifting device 120 may also be called a window lifter, which is not limited in the present application.

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

[0065] The clamp 121 may also be called a fixing clip and is configured to clamp and fix the vehicle door glass 110. Optionally, in an actual structure, one clamp 121 may be used, or two or more clamps 121 may be used, without being limited thereto.

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

[0067] The slide rail 123, which may also be called a track, includes a slider groove. The slider groove is configured to limit 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 slidable 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 , and the slider 122 is pulled by the operation of the pull cable 124 so as to slide up and down inside the slide rail 123 .

[0070] The motor and winch 126 provides power to the lifting system and is configured to pull and move the pull cable 124 by rotation of the winch.

[0071] The overall working principle of the lifting device 120 is as follows: the motor drives and rotates the winch, which pulls and moves the pull cable 124, which generates linear displacement inside the slide rail 123 using pulleys 125A and 125B to drive the slider 122 to move up and down along the slide rail 123. The slider 122 is connected to the vehicle door glass 110 using a clamp 121, so that 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, vehicle door glass is not powered. However, with the development of science and technology, users have higher requirements for vehicle door glass and expect it to be able to perform various functions, such as privacy, sunshade, dimming, color adjustment, display, and touch. In order for the vehicle door glass to perform the aforementioned functions, power needs to be supplied to the vehicle door glass. Therefore, how to supply power to vehicle door glass is a technical problem that needs to be solved urgently.

[0073] Based on this, in the embodiment of the present application, based on the conventional slide rail and the conventional slider, a drag chain harness and a drag chain harness groove used to accommodate the drag chain harness are added, 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 moved device such as the vehicle door glass in order to supply power to the moved device such as the vehicle door glass.

[0077] Optionally, the slider 220 may be used to fix the moved device 201 using a fixing device. For example, the fixing device may be a clamp 250 shown in FIG. 2. Specifically, the clamp 250 may be placed on the slider 220, and then the moved device 201 is clamped and fixed using the clamp 250.

The drag chain harness 240 includes a fixed end 241 electrically connected to a power source and a movable end 242 electrically connected to the moved device 201, so that power can be supplied to the moved device 201.

[0081] In addition, 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. Also, the drag chain harness 240 is disposed in the drag chain harness groove 230, which can avoid the problem of the harness being wound and tangled, and the drag chain harness groove 230 can provide guidance and restriction for the drag chain harness 240 to prevent problems such as shaking and abnormal noise generated during the operation process of the drag chain harness 240.

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

[0084] The drag chain harness groove 230 of the power supply device 200 provided in this embodiment of the present application can be disposed on the slide rail 210. In this way, the integration degree of the power supply device 200 is higher, thereby saving space. In addition, it can be ensured that the track direction of the drag chain harness groove 230 coincides with the track direction of the slide rail 210, thereby ensuring the consistency of the movement paths of the drag chain harness 240 and the slider 220.

[0085] In another embodiment, the drag chain harness groove 230 may be secured to the slide rail 210 using a support 231, as shown in Figure 5.

This is not limited.

[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 directly fixed based on the conventional slide rail 210 using the support 231, and the conventional slide rail 210 does not need to be improved, thereby reducing the complexity of the manufacturing process.

This is not a limitation in the present application.

[0090] In this embodiment of the present application, the positional allocation of the drag chain harness groove 230 and the slider groove 211 in the cross section is not limited and may be flexibly set. Optionally, the drag chain harness groove 230 and the slider groove 211 may be arranged along a first direction, or the drag chain harness groove 230 and the slider groove 211 may be arranged along a second direction, and the first direction and the second direction may form a first included 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 moved device 201 is located, i.e., the x direction shown in FIG. 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 moved device 201 is located, i.e., the y direction shown in FIG. 2, and the first included angle is 90°.

[0092] In this case, when 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 can face the plane in which the moved device 201 is located (as shown in Figures 2, 5, and 6), thereby ensuring the alignment of the movement paths of the drag chain harness 240 and the slider 220.

[0093] When the drag chain harness groove 230 and the slider groove 211 are arranged along the second direction, the opening of the drag chain harness groove 230 may face the plane on which the moved device 201 is located, or the drag chain harness groove 230 may be arranged 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 FIG. 4 ). In this manner, the integration of the power supply device is higher, thereby saving space. It can also be ensured that the track direction of the drag chain harness groove matches the track direction of the slider groove, thereby ensuring the consistency of the movement paths of the drag chain harness and the slider. Optionally, in this case, the cross sections of the drag chain harness groove 230 and the slider groove 211 may be in the shape of an inverted "T" or a modified form of the inverted "T." This is not limited thereto.

[0094] Optionally, power supply device 200 may further include a limiter 260. For limiter 260, see Figures 2 to 6.

[0095] Optionally, limiter 260 may be arranged on slider 220, clamp 250, or moved device 201, etc., and limiter 260 can move together with movable end 242 and is configured to limit the protrusion of movable end 242 on the cross section of power supply device 200 away from the protrusion of fixed end 241 to prevent situations such as shaking or abnormal noise generated by movable end 242 of drag chain harness 240 during the movement process.

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

[0097] Optionally, the limiter 260 may include any one of a baffle plate, a stopper, an upper stiffening bar, etc., but is not limited thereto.

[0098] The positional allocation of the fixed end 241 and the movable end 242 in the cross section is not limited in 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 the fixed end 241 and the movable end 242 may be arranged along a fourth direction, and the third direction and the fourth direction may form a second included angle.

[0099] Optionally, the third direction may be perpendicular to the track direction of the slide rail 210 and parallel to the plane in which the moved device 201 is located (i.e., the aforementioned x-direction). When the fixed end 241 and the movable end 242 are arranged along this direction, the direction of the connection pins of each section of the drag chain is perpendicular to the plane in which the moved device 201 is located, which may also be understood as the plane formed by the movement path of the drag chain being parallel to the plane in which the moved device 201 is located, as shown in Fig. 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 device 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 in which the moved 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 direction of the connection pins of each section of the drag chain is parallel to the plane in which the moved device 201 is located, which may also be understood as the plane formed by the movement path of the drag chain being perpendicular to the plane in which the moved 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 device and saves space.

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

[0102] In actual practice, 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°, which is not a limitation of the present application.

[0103] In this embodiment of the present application, the movable end 242 may move with the moved device 201 .

[0104] Optionally, the movable end 242 being configured to electrically connect to the moved device 201 may be implemented in the following two embodiments.

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

[0106] In another embodiment, the movable end 242 may be directly electrically connected to the moved device 201, i.e., the movable end 242 is directly fixed to the moved device 201. In this embodiment, the harness of the movable end 242 is protected by the 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 secured to the slider 220, the clamp 250, the moved device 201, or the like using a conductive structure. The conductive structure may be, but is not limited to, a connector or another conductive connecting structure.

[0108] Optionally, the fixed end 241 may be electrically connected directly to a power source or may be electrically connected to a power source using a harness, without being limited thereto.

[0109] Optionally, power supply device 200 may further include pull cable 270, pull cable 270 connected to slider 220 and configured to pull slider 220 to move on slide rail 210, pulley 280, including pulleys 280A and 280B, disposed at both ends of slide rail 210 and configured to provide operating guidance and a turning radius for pull cable 270, and motor and winch 290, motor and winch 290 configured to provide power to pull and move pull cable 270 by rotation of the winch.

[0110] Optionally, the fixed end 241 may be fixed at both ends of the travel stroke, or may be fixed between both ends of the travel stroke, for example, at the midpoint of the travel stroke or another position. Figure 7 is an exemplary diagram of the position of the fixed end 241 according to one embodiment of the present application. Figure 7(a) shows that the fixed end 241 is fixed at the top of the travel stroke, and Figure 7(b) shows that the fixed end 241 is fixed between both ends of the travel stroke. When the fixed end 241 is fixed between both 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, fixed end 241 may be fixed to both ends of drag chain harness groove 230, or may be fixed at a first position between both ends of drag chain harness groove 230. When fixed end 241 is fixed between both ends of drag chain harness groove 230, the length of drag chain harness 240 can be reduced, and the weight and cost of drag chain harness 240 can be reduced, compared to when fixed end 241 is fixed to both ends of drag chain harness groove 230.

[0112] For example, when the aforementioned motor is disposed 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 when 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 above-mentioned position of the fixed end 242 is merely an example. In actual operation, the specific position at which the fixed end 242 is fixed is determined based on the actual situation, which is not limited in the present application, as long as the fixed end 242 is stationary relative to the drag chain harness groove 230.

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

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

[0119] In addition, 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 direct use of the harness. Also, the drag chain harness is arranged in the drag chain harness groove, which can avoid the problem of the harness being wound and tangled, and the drag chain harness groove can provide guidance and restriction for the drag chain harness to prevent problems such as shaking and abnormal noise generated during the operation process of the drag chain harness.
