[0048] Optionally, the mobile terminal can be fixed to a slider, a clip, or a device to be moved, etc., via a conductive structure. The conductive structure can be a connector or other conductive connection structure, which is not limited.

[0068] The technical solutions in the embodiments of the present application will be described below with reference to the accompanying drawings.

[0069] The power supply device provided by the present application can be applied to the fields of transportation, smart homes, buildings, etc. Among them, the transportation can include one or more different types of transportation vehicles or movable objects that operate or move on land (e.g., highways, roads, railways, etc.), water surfaces (e.g., waterways, rivers, oceans, etc.), or space. For example, the transportation can include vehicles (e.g., smart vehicles), bicycles, motorcycles, trains, subways, airplanes, ships, aircraft, robots, or other types of transportation vehicles or movable objects.

[0070] Taking vehicles in the field of transportation as an example, the power supply device provided by the present application solution can provide power to the door glass while providing the lifting function, so that the door glass can achieve different functions such as dimming, color adjustment, display and touch control; the power supply device provided by the present application solution can also provide power to the laser radar, audio and other equipment on the vehicle while providing the movement or lifting function, so that the laser radar, audio and other equipment can change their position according to the user's needs while working normally. Taking the smart home field as an example, the power supply device provided by the present application solution can provide power to display screens, televisions or screens while providing the lifting or movement function, so that the display screens, televisions or screens can achieve different functions such as dimming, color adjustment, display and touch control. Taking the building field as an example, the power supply device provided by the present application solution can provide power to building glass, roof skylights, etc. while providing the lifting or movement function, so that the building glass, roof skylights, etc. can achieve different functions such as dimming, color adjustment, display and touch control.

[0071] 1 , taking vehicle 100 as an example, the background technology involved in the embodiments of the present application will be briefly introduced.

[0072] Figure 1 illustrates an example of a conventional vehicle. As shown in Figure 1 , vehicle 100 includes a door, which includes a door glass 110 and a door glass lifting mechanism 120. Lifting mechanism 120 is typically located within the door sheet metal. Alternatively, in the vehicle field, lifting mechanism 120 may also be referred to as a window regulator, though this application does not limit this term.

[0073] As shown in FIG. 1 , the lifting device 120 may include a clamp 121 , a slider 122 , a slide rail 123 , a cable 124 , a pulley 125 , a motor, and a winch 126 .

[0074] The clip 121, which may also be referred to as a fixing clip, is used to clamp and fix the door glass 110. Optionally, one clip 121, or two or more clips 121 may be used in the actual structure, without limitation.

[0075] The slider 122 is used to connect to the clamp 121 and slide up and down inside the slide rail 123. As shown in Figure 1, the slider 122A is the highest position the slider can slide to, and the slider 122B is the lowest position the slider can slide to.

[0076] The slide rail 123, also known as a track, includes a slider groove that constrains the sliding trajectory of the slider 122. The slide rail 123 typically has a flange that couples with the slider 122 to form a slidable system. Alternatively, the slider groove can be formed by stamping or extrusion, and its cross-section can be U-shaped, V-shaped, C-shaped, or the like, without limitation.

[0077] The cable 124 is connected to the slider 122 , and the movement of the cable 124 pulls the slider 122 to slide up and down inside the slide rail 123 .

[0078] The pulley 125 is used to provide motion guidance and a suitable turning radius for the cable 124. Optionally, the pulley 125 may include pulleys 125A and 125B, which are respectively arranged at the upper and lower ends of the slide rail 123.

[0079] The motor and winch 126 are used to provide power to the lifting system and to rotate the traction cable 124 to move.

[0080] The overall working principle of the above-mentioned lifting device 120 is: the motor drives the winch to rotate, the winch pulls the cable 124 to move, and the cable 124 forms a linear displacement inside the slide rail 123 through the pulleys 125A and 125B, driving the slider 122 to move up and down along the slide rail 123. Since the slider 122 is connected to the car door glass 110 through the clamp 121, the slider 122 can drive the car door glass 110 to rise and fall during the up and down movement of the slider 122.

[0081] As can be seen, in traditional vehicles, door glass is not powered. However, with the advancement of science and technology, users have higher demands on door glass, hoping that it can provide various functions such as privacy, sunshade, dimming, color adjustment, display, and touch control. To achieve these functions, the door glass must first be powered. Therefore, how to achieve power supply for door glass is a technical problem that needs to be solved urgently.

[0082] Based on this, the embodiment of the present application adds a drag chain harness and a drag chain harness groove for storing the drag chain harness on the basis of traditional slide rails and sliders, and electrically connects the fixed end of the drag chain harness to the power supply, and the movable end to the door glass waiting movable device, so as to realize power supply to the door glass waiting movable device.

[0085] The slider 220 can move along the track direction of the slide rail 210. As shown in Figure 2, the slider 220A is the highest position to which the slider 220 can slide, and the slider 220B is the lowest position to which the slider 220 can slide.

[0086] Optionally, the slider 220 can secure the device 201 to be moved using a securing device. For example, the securing device can be the clip 250 shown in FIG2 . Specifically, the clip 250 can be disposed on the slider 220, and then the device 201 to be moved can be secured by the clip 250. Alternatively, a single clip 121 can be used in the actual structure, or two or more clips 121 can be used, and this application does not limit this.

[0087] The drag chain harness 240 includes a drag chain and a harness wrapped by the drag chain. The drag chain includes a plurality of chain links, which can be connected by connecting pins.

[0088] Optionally, the movable device 201 may include glass, display screens, curtains, televisions, skylights, laser radars, speakers, cameras, and the like, which are involved in the fields of transportation, smart homes, buildings, and smartphones, and this application does not limit this. The above-mentioned movement includes lifting, left-right, and forward-backward movement, and this application does not limit the movement direction of the movable device 201.

[0089] The power supply device 200 provided in the embodiment of the present application mainly adds a drag chain harness groove 230 and a drag chain harness 240 on the basis of the slide rail 210 and the slider 220, wherein the drag chain harness groove 230 is fixed to the slide rail 210, and the drag chain harness 240 is arranged in the drag chain harness groove 230. The drag chain harness 240 includes a fixed end 241 electrically connected to the power supply and a movable end 242 electrically connected to the device to be moved 201, thereby enabling power supply to the device to be moved 201.

[0090] In addition, in the embodiment of the present application, a drag chain harness 240 is used to protect and restrain the internal harness with the drag chain, so as to avoid the problem of poor durability of the harness caused by direct use of the harness; moreover, the drag chain harness 240 is arranged in the drag chain harness groove 230, which can avoid the problem of harness entanglement and knotting on the one hand, and on the other hand, the drag chain harness groove 230 can provide guidance and limitation for the drag chain harness 240, so as to prevent the drag chain harness 240 from shaking, abnormal noise and other problems during movement.

[0091] Optionally, the drag chain harness trough 230 can be fixed to the slide rail 210 in a variety of ways.

[0092] As an implementation method, the drag chain harness groove 230 can be directly provided on the slide rail 210. Specifically, the drag chain harness groove 230 can be provided on the slide rail 210 along the track direction of the slide rail 210, as shown in Figures 2 and 4. The drag chain harness groove 230 is provided on the slide rail 210, which can be understood as the drag chain harness groove 230 and the slide rail 210 being integrally formed.

[0093] The drag chain harness groove 230 in the power supply device 200 provided in the embodiment of the present application can be set on the slide rail 210. On the one hand, it makes the power supply device 200 more integrated, thereby saving space; on the other hand, it can ensure that the track direction of the drag chain harness groove 230 is consistent with that of the slide rail 210, thereby ensuring the consistency of the movement trajectory of the drag chain harness 240 and the slider 220.

[0094] As another implementation, the drag chain harness trough 230 can be fixed to the slide rail 210 by a bracket 231, see Figure 5. In the embodiment of the present application, one bracket 231 can be used to fix the drag chain harness trough 230 to the slide rail 210, or multiple brackets 231 can be used to fix the drag chain harness trough 230 to the slide rail 210, without limitation.

[0095] In an embodiment of the present application, the drag chain harness trough 230 can be fixed on the slide rail 210 by the bracket 231, which means that the drag chain harness trough 230 can be directly fixed on the traditional slide rail 210 by the bracket 231 without the need to improve the traditional slide rail 210, thereby reducing the complexity of the preparation process.

[0096] As another implementation method, the drag chain harness groove 230 can also be fixed to the slide rail 210 by bonding or welding.

[0097] Optionally, the slide rail 210 may include a slider groove 211, in which the slider 220 is disposed. The slider groove 211 is used to constrain the sliding trajectory of the slider 220. The slide rail 210 generally has a flange that can be coupled to the slider 220 to form a slidable system.

[0098] Optionally, the slider groove 211 can be formed by stamping or extrusion, and its cross-section can be "U"-shaped, "V"-shaped, "C"-shaped, etc., without limitation. Similarly, the drag chain harness groove 230 can also be formed by stamping or extrusion, and its cross-section can be "U"-shaped, "V"-shaped, "C"-shaped, etc., without limitation. The cross-sections of the slider groove 211 and the drag chain harness groove 230 can be the same, for example, both are "U"-shaped; or they can be different, for example, one is "U"-shaped and the other is "V"-shaped, and this application does not limit this.

[0099] The embodiment of the present application does not limit the positional distribution of the drag chain harness groove 230 and the slider groove 211 in the cross section, and can be flexibly configured. Optionally, the drag chain harness groove 230 and the slider groove 211 can be distributed along a first direction; or, the drag chain harness groove 230 and the slider groove 211 can be distributed along a second direction, wherein the first direction and the second direction can form a first angle.

[0100] Exemplarily, the first direction can be perpendicular to the track direction of the slide rail 210 and parallel to the plane where the device to be moved 201 is located, that is, the x direction shown in Figure 2; the second direction can be perpendicular to the track direction of the slide rail 210 and perpendicular to the plane where the device to be moved 201 is located, that is, the y direction shown in Figure 2, and the first angle is 90°.

[0101] In this case, if the drag chain harness groove 230 and the slider groove 211 are distributed along the first direction, the groove openings of the drag chain harness groove 230 and the slider groove 211 can face the plane where the movable device 201 is located (as shown in Figures 2, 5 and 6), thereby ensuring the consistency of the movement trajectory of the drag chain harness 240 and the slider 220.

[0102] If the drag chain harness groove 230 and the slider groove 211 are distributed along the second direction, the notch of the drag chain harness groove 230 can face the plane where the mobile device 201 is located, and the drag chain harness groove 230 can be set on the side of the slider groove 211 and away from the slider groove 211, and the notch of the drag chain harness groove 230 faces the slider groove 211 (as shown in Figure 4), so that on the one hand, the integration of the power supply device is higher and space is saved; on the other hand, it can ensure that the track direction of the drag chain harness groove and the slider groove is consistent, thereby ensuring the consistency of the movement trajectory of the drag chain harness and the slider. Optionally, in this case, the cross-section of the drag chain harness groove 230 and the slider groove 211 can be a "convex" shape or a variant of the "convex" shape, without limitation.

[0103] Optionally, the power supply device 200 may further include: a limiter 260 , see the limiter 260 shown in FIG. 2 to FIG. 6 .

[0104] Optionally, the limiter 260 can be set on the slider 220, the clamp 250 or the device to be moved 201, etc., which can move with the mobile end 242, and is used to limit the projection of the mobile end 242 in the cross section of the power supply device 200 from moving away from the projection of the fixed end 241, thereby preventing the mobile end 242 of the drag chain harness 240 from shaking or making abnormal noises during movement.

[0105] Optionally, the embodiment of the present application does not limit the length of the limiter 260. For example, the length of the limiter 260 can be determined according to the length of 3-5 sections of the drag chain.

[0106] Optionally, the limiter 260 may include any one of a baffle, a block, a top rib, etc., without limitation.

[0107] The embodiment of the present application does not limit the positional distribution of the fixed end 241 and the movable end 242 on the cross section, and can be flexibly configured. Optionally, the fixed end 241 and the movable end 242 can be distributed along a third direction; or, the fixed end 241 and the movable end 242 can be distributed along a fourth direction, wherein the third direction and the fourth direction can form a second angle.

[0108] Alternatively, the third direction can be perpendicular to the track direction of the slide rail 210 and parallel to the plane where the device to be moved 201 is located (i.e., the x-direction described above). If the fixed end 241 and the movable end 242 are distributed along this direction, the connecting pins of each section of the drag chain are perpendicular to the plane where the device to be moved 201 is located. This can also be understood as the plane formed by the drag chain's motion trajectory being parallel to the plane where the device to be moved 201 is located (see Figure 6). In this case, the drag chain harness slot 230 occupies less space, thereby making the power supply device more integrated and saving space.

[0109] Optionally, the fourth direction can be perpendicular to the track direction of the slide rail 210 and perpendicular to the plane where the device to be moved 201 is located (i.e., the aforementioned y-direction). If the fixed end 241 and the movable end 242 are distributed along this direction, the connection pins of each section of the drag chain are parallel to the plane where the device to be moved 201 is located. This can also be understood as the plane formed by the drag chain's motion trajectory being perpendicular to the plane where the device to be moved 201 is located, as shown in Figures 2 to 5. In this case, the drag chain harness slot 230 occupies less space, thereby making the power supply device more integrated and saving space.

[0110] Based on this, the second angle may be 90°.

[0111] In actual operation, the third direction and the fourth direction can be the x direction and the y direction respectively, or they can slightly deviate from the x direction and the y direction; the second angle can be 90° or close to 90°, which is not limited in this application.

[0112] In the embodiment of the present application, the mobile terminal 242 can move together with the device to be moved 201 .

[0113] Optionally, the mobile terminal 242 can be electrically connected to the mobile device 201 in the following two ways:

[0114] In one implementation, the mobile terminal 242 is indirectly electrically connected to the device to be moved 201 via an extension harness. For example, the mobile terminal 242 can be fixed to a component that can move together with the device to be moved 201, such as a slider 220 or a clamp 250, and then electrically connected to the device to be moved 201 via the extension harness. In this implementation, on the one hand, since the components that can move together with the device to be moved 201, such as the slider 220 or the clamp 250, are stationary relative to the device to be moved 201, the extension harness is not dragged or pulled during movement, thereby ensuring the durability of the extension harness. On the other hand, the harness in the mobile terminal fixed to the components that can move together with the device to be moved 201, such as the slider 220 or the clamp 250, is protected by a tow chain, thereby preventing the harness from being directly dragged or pulled during movement, thereby ensuring the durability of the harness.

[0115] In another implementation, the mobile terminal 242 can be directly electrically connected to the device to be moved 201, that is, the mobile terminal 242 can be directly fixed to the device to be moved 201. In this implementation, since the wiring harness in the mobile terminal 242 is protected by a drag chain, it can avoid direct dragging and pulling of the wiring harness during movement, thereby ensuring the durability of the wiring harness.

[0116] Optionally, the movable end 242 can be fixed to the slider 220, the clamp 250 or the device to be moved 201 through a conductive structure. The conductive structure can be a connector or other conductive connection structure, which is not limited.

[0117] Optionally, the fixed end 241 may be directly electrically connected to the power source, or may be electrically connected to the power source through a wiring harness, without limitation.

[0118] Optionally, the power supply device 200 may also include: a cable 270, which is connected to the slider 220 and is used to pull the slider 220 to move on the slide rail 210; a pulley 280, which includes pulleys 280A and 280B, and is arranged at both ends of the slide rail 210 to provide motion guidance and turning radius for the cable 270; a motor and a winch 290, which are used to provide power to pull the cable 270 to move through the rotation of the winch.

[0119] Optionally, the fixed end 241 can be fixed at both ends of the moving stroke, or fixed between the two ends of the moving stroke, for example, at the midpoint of the moving stroke or other positions. Figure 7 is an example diagram of the position of the fixed end 241 provided in an embodiment of the present application, wherein (a) in Figure 7 shows the fixed end 241 fixed at the top of the moving stroke, and (b) in Figure 7 shows the fixed end 241 fixed between the two ends of the moving stroke. As shown in Figure 7, fixing between the two ends of the moving stroke significantly reduces the length of the drag chain harness 240, thereby reducing the weight and cost of the drag chain harness 240.

[0120] For example, the fixed end 241 can be fixed at both ends of the drag chain harness groove 230, or fixed at a first position between the two ends of the drag chain harness groove 230. Fixing the fixed end 241 between the two ends of the drag chain harness groove 230 can reduce the length of the drag chain harness 240, and reduce the weight and cost of the drag chain harness 240, compared to fixing it at both ends of the drag chain harness groove 230.

[0121] For example, if the motor is disposed between the two ends of the slide rail 210, the fixed end 241 can also be fixed to the motor. In this case, fixing the fixed end 241 to the motor can reduce the length, weight, and cost of the drag chain harness 240 compared to fixing it to the two ends of the drag chain harness slot 230.

[0122] The position of the above-mentioned fixed end 242 is only an example. In actual operation, the specific fixed position is determined based on the actual situation. This application does not limit this. It only needs to remain relatively stationary with the drag chain harness groove 230.

[0123] The overall working principle of the above-mentioned power supply device 200 is: the motor drives the winch to rotate, the winch pulls the cable 270 to move, and the cable 270 forms a linear displacement inside the slide rail 210 through the pulleys 280A and 280B, driving the slider 220 to move up and down along the slide rail 210. Since the slider 220 is connected to the device to be moved 201 through the clamp 250, the slider 220 can drive the device to be moved 201 to move during the up and down movement; at the same time, the drag chain harness 240 can transmit the power of the power supply to the device to be moved 201 to power the device to be moved 201.

[0124] Optionally, the embodiment of the present application may also introduce a communication harness into the drag chain harness to enable the mobile device 201 to communicate with other devices.

[0128] In addition, in the embodiment of the present application, a drag chain harness is used to protect and restrain the internal harness with the drag chain, avoiding the problem of poor durability of the harness caused by direct use of the harness; moreover, the drag chain harness is arranged in a drag chain harness groove, which can avoid the problem of harness entanglement and knotting on the one hand, and on the other hand, the drag chain harness groove can provide guidance and limitation for the drag chain harness, preventing the drag chain harness from shaking, abnormal noise and other problems during movement.

[0129] In one implementation, the drag chain harness trough may be fixed to the vehicle door.

[0130] Optionally, the drag chain harness groove can be integrally formed with the vehicle door, or it can be fixed to the vehicle door through a bracket or other connectors, or it can be fixed to the vehicle door by bonding or welding, etc. This application does not limit this.
