[0002] Currently, traditional automotive sliding rail assemblies are typically mechanical structures, primarily used for installing sunshades. Their simple structure only provides linear sliding functionality, lacking power transmission capabilities and unable to support the installation and expansion of electronic devices. While some vehicles can have fixed power interfaces or independent brackets in the headliner area for mounting cameras, lights, and other equipment, these solutions are mostly aftermarket modifications, lacking a standardized sliding power supply platform.

[0027] Combination Figures 1 to 6As shown, this embodiment provides a vehicle slide rail assembly that enables peripherals mounted on the crossbeam 10 of the slide rail assembly to obtain a stable power supply at any sliding position. This achieves convenient power supply and quick access to external modular devices, significantly improves the functional expandability of the cabin space and the user's DIY freedom, and enhances the overall vehicle's intelligence level and technological experience.

[0028] Combination Figures 1 to 5 As shown, the slide rail assembly includes a slide rail 20, an electric rail 30, a crossbeam 10, and a brush 40. The slide rail 20 is provided with a groove 201; the electric rail 30 is located in the groove 201 and connected to the slide rail 20; one end of the crossbeam 10 passes through the groove 201, and the brush 40 is connected to the crossbeam 10 and moves synchronously with the crossbeam 10; wherein, when the crossbeam 10 moves along the length direction of the slide rail 20 in the groove 201, the brush 40 keeps in contact with the electric rail 30. The crossbeam 10 is provided with a power input interface, one end of which is electrically connected to the brush 40, and the other end is used to connect external electrical equipment.

[0029] For example, the groove 201 is an arc-shaped groove adapted to the curvature of the roof to ensure that the movement trajectory of the crossbeam 10 is consistent with the body surface; the width and depth of the groove 201 must match the end dimensions of the crossbeam 10 and the installation space of the brush 40. The inner wall of the groove 201 is polished or nickel-plated to reduce the sliding resistance of the brush 40 and improve contact stability. Optionally, the groove 201 has a groove width of 12–25 mm and a groove depth of 8–20 mm.

[0030] For example, combined Figures 3 to 5 As shown, the electric rail 30 is a conductive component installed inside the slide 201, used to transmit electrical energy to the moving parts. The electric rail 30 is fixed to the inner wall of the slide 201 by riveting, laser welding or conductive adhesive bonding to ensure that it does not loosen under long-term vibration conditions.

[0031] Optionally, the electric rail 30 can be made of copper alloy strip, silver-plated aluminum busbar or conductive polymer coating structure, and can be laid continuously or spliced ​​in segments along the length of the chute 201; its cross-section is flat and rectangular, with a thickness of 0.8–2.5 mm and a width of 4–12 mm, to ensure current carrying capacity and mechanical fit.

[0032] For example, the crossbeam 10 is a transverse load-bearing member that can slide along the groove 201, with one end extending into the groove 201 to form a sliding fit (i.e., Figure 4 The connecting section 12 in the middle is located outside the slide 201, and is used to install peripheral modules such as lamps, sensors, and displays.

[0033] Optionally, the crossbeam 10 can be made of magnesium-aluminum alloy die casting, carbon fiber reinforced composite profile or high-strength engineering plastic injection molding, taking into account rigidity, lightweight and electromagnetic shielding performance.

[0034] For example, combined Figures 3 to 6 As shown, the brush 40 is an elastic conductive contact that is directly connected to the crossbeam 10 and moves synchronously with it. Its function is to continuously collect electrical energy from the rail 30 during the sliding process of the crossbeam 10. The brush 40 is fixed to the crossbeam 10 by screws, clips, or an embedded structure, and its contact end face is ground and polished to maintain low-resistance sliding contact.

[0035] Alternatively, the brush 40 may be made of a copper-zinc alloy (brass), a copper-beryllium alloy, or a graphite-impregnated metal matrix composite material, which has high conductivity, good elasticity, and wear resistance.

[0036] For example, the power input interface (not shown) is an electrical connection port located on the crossbeam 10, used to output the electrical energy obtained by the brush 40 to an external electrical device; the interface can be a plug-in interface conforming to USB Type-C, Molex Micro-Fit 3.0, JSTXH series or ISO / IEC 62196-2 standards, or it can be a PCB gold finger contact, a pogo pin array or a bare wire crimp terminal.

[0037] Optionally, the interface is located on the exposed section of the crossbeam 10. Figure 4 The main beam section 11) side wall. The power interface supports voltage levels of 12VDC (for vehicle power supply) or 24VDC (for commercial vehicle platforms).

[0038] It should be understood that when the crossbeam 10 slides in the slide groove 201 along the length of the slide rail 20, the brush 40 moves synchronously because it is fixed to the crossbeam 10, and its contact end face is always elastically pressed against the surface of the electric rail 30 to form a continuous conductive path; the electrical energy is introduced into the internal wire network of the crossbeam 10 through the brush 40, and is stably output to the connected peripheral module through the power input interface.

[0039] In this invention, an electric rail 30 is first integrated into the slide groove 201 of the slide rail 20, and then a brush 40 structure that moves with the crossbeam 10 is set up so that the brush 40 and the electric rail 30 maintain sliding contact during the sliding process of the crossbeam 10. This allows the crossbeam 10 to continuously draw power during the sliding process, ensuring the continuity of power supply and solving the problem that the traditional slide rail 20 cannot supply power to moving electronic devices. Finally, in conjunction with the power interface on the crossbeam 10, convenient power supply and quick access to external modular devices are realized, significantly improving the functional expandability of the cabin space and the user's DIY freedom, and enhancing the overall vehicle's intelligence level and technological experience.

[0040] In this embodiment, the vehicle roof is an arc-shaped roof. The slide 201 is an arc-shaped groove, the overall shape of which is adapted to the arc-shaped contour of the vehicle roof. It can be arranged to extend along the axial direction of the vehicle and is used to guide the movement path of the crossbeam 10 and its connecting components.

[0041] Combination Figure 5 As shown, one end of the crossbeam 10 is provided with a guide wheel 50, which is located in the arc groove and rotates in the slide groove 201 along the length of the slide rail 20.

[0042] For example, the guide wheel 50 is mounted on the crossbeam 10 via a rotating shaft. One end of the rotating shaft can be fixedly connected to the guide wheel 50, and the other end is connected to the crossbeam 10 via a bearing structure, so as to enable the guide wheel 50 to rotate relative to the crossbeam 10, ensuring that the guide wheel 50 can flexibly adapt to local curvature changes without jamming when it travels in the slide groove 201.

[0043] Optionally, the number of guide wheels 50 is not limited to a single one. When there are multiple guide wheels, they can be symmetrically arranged on two opposite sides of the crossbeam 10 to improve the smoothness of movement.

[0044] Optionally, the guide wheel 50 may be made of metal (such as stainless steel or aluminum alloy) and covered with an elastic wear-resistant material (such as polyurethane or nylon) to reduce operating noise and improve friction adaptability; or it may be integrally injection molded from engineering plastics to reduce weight and provide self-lubricating properties.

[0045] It should be understood that because the slide rail 201 is an arc-shaped groove that matches the shape of the vehicle's roof, the entire slide rail assembly can match the mainstream automotive streamlined design (arc roof). This avoids stress concentration or aesthetic inconsistencies that would result from forcibly installing a straight slide rail 20 and slide rail 201 onto the curved surface of an arc roof. Furthermore, the introduction of the guide wheel 50 converts most of the friction into rolling friction, significantly reducing starting torque and running resistance, improving smoothness and durability during sliding, and enabling convenient power supply and rapid connection to external modular devices even on new energy vehicles with highly curved roofs.

[0046] In this embodiment, the slide rail assembly further includes a drive assembly. The crossbeam 10 includes a main beam section 11 and a connecting section 12. The connecting section 12 is connected to the main beam section 11, and one end of the connecting section 12 is located in the slide groove 201. The brush 40 is connected to the connecting section 12. The electric rail 30 is located above the connecting section 12 along the thickness direction of the crossbeam 10. The drive assembly is located below the connecting section 12 along the thickness direction of the crossbeam 10 and is connected to the connecting section 12. The guide wheel 50 includes a first roller 51 and a second roller 52. The first roller 51 and the second roller 52 are correspondingly arranged on both sides of the connecting section 12 along the width direction of the crossbeam 10 and are connected to the connecting section 12.

[0047] For example, the brush 40 is disposed on the upper part of the connecting section 12 and keeps in contact with the rail 30. By utilizing the positional relationship of the rail 30 above the connecting section 12, the brush 40 can be tightly attached to the lower surface of the rail 30 by the elastic preload, so as to achieve continuous conductive connection during the sliding process.

[0048] Alternatively, the brush 40 can be made of a flexible copper alloy material, such as phosphor bronze or beryllium copper, which has good conductivity and fatigue resistance; it can also be replaced with a graphite-based composite brush 40, which maintains stable tribological properties in high temperature or high humidity environments.

[0049] For example, the drive motor 60 can be a DC brushless motor, which has the advantages of small size, fast response and low noise. The installation position is not limited to the end of the slide rail 20, but can also be set near the side of the vehicle body or the roof frame, and remote transmission can be achieved through an extended conveyor belt.

[0050] For example, the drive assembly is located below the connecting section 12, and is arranged in a layered manner with the brush 40 in the thickness direction of the crossbeam 10, effectively avoiding spatial interference between the arrangement of the drive assembly and the arrangement of the brush 40 and the electric rail 30. The transmission component 70 can be fixedly connected to the connecting section 12 by threaded fasteners, snap-fit ​​structures, or welding, ensuring reliable transmission of driving force to the crossbeam 10.

[0051] For example, the drive assembly includes a transmission component 70 and a drive motor 60. The transmission component 70 passes through the slide groove 201 along the length of the slide rail 20 and is connected to the connecting section 12. The drive motor 60 is driven by the transmission component 70. The transmission component 70 includes a conveyor belt that is driven by the drive motor 60. The conveyor belt is located below the connecting section 12 and is connected to the connecting section 12.

[0052] In another alternative embodiment, the drive assembly may be replaced by a pneumatic or hydraulic push rod device; or, the drive assembly may be replaced by a rack and pinion mechanism, a lead screw and nut pair, or a linear motor, etc.

[0053] For example, the first roller 51 and the second roller 52 can be rotatably connected to the connecting section 12 via a shaft or bearing structure.

[0054] It should be understood that by placing the electric rail 30 above the connecting section 12 and the drive component below, and by providing lateral support through the symmetrically arranged first roller 51 and second roller 52, the power transmission, mechanical transmission and motion guidance do not interfere with each other in space, thus solving the technical problem of chaotic multi-system layout and easy interference in the traditional slide rail 20.

[0055] In this embodiment, combined with Figure 4 and Figure 5As shown, the slide rail 20 includes a top plate 21, a bottom plate 22, a right side plate 23, and a left side plate 24 that form a slide groove 201. The right side plate 23 and the left side plate 24 are arranged opposite each other along the length direction of the crossbeam 10. The right side plate 23 is connected between the top plate 21 and the bottom plate 22, and the left side plate 24 is connected to the bottom plate 22. The left side plate 24 and the right side plate 23 are spaced apart. A first opening communicating with the slide groove 201 is provided between the left side plate 24 and the top plate 21. A positioning groove 101 is provided on the bottom surface of the connecting section 12. The top of the left side plate 24 passes through the positioning groove 101 and is arranged opposite to the groove wall of the positioning groove 101 along the length direction of the crossbeam 10.

[0056] It should be understood that the engagement between the left side plate 24 of the slide rail 20 and the bottom positioning groove 101 of the connecting section 12 effectively constrains the movement of the crossbeam 10 in the length direction. The slide rail 20 as a whole is formed by the top plate 21, the bottom plate 22, the right side plate 23 and the left side plate 24, which together enclose the slide groove 201, providing space for the crossbeam 10 and its auxiliary components.

[0057] Furthermore, the left side plate 24 is only connected to the bottom plate 22 and is spaced apart from the top plate 21, thereby forming a first opening between the left side plate 24 and the top plate 21. This first opening extends through the width direction of the slide rail 20 (that is, the length direction of the crossbeam 10), thereby allowing the connecting section 12 and the brush 40 to extend into the slide groove 201 to realize power or data transmission functions.

[0058] Combination Figure 3 and Figure 4 As shown, the slide rail 20 also includes a right limiting plate 25 and a left limiting plate 26 located in the slide groove 201. The right limiting plate 25 is connected to the right side plate 23 and is spaced apart from the bottom plate 22 and the top plate 21. The left limiting plate 26 is opposite to the right limiting plate 25 and is connected to the left side plate 24 and is spaced apart from the bottom plate 22 and the top plate 21. The connecting section 12 is located between the right limiting plate 25 and the left limiting plate 26. The first roller 51 slides between the right limiting plate 25 and the bottom plate 22 along the length direction of the slide rail 20, and the second roller 52 slides between the left limiting plate 26 and the bottom plate 22 along the length direction of the slide rail 20.

[0059] In this embodiment, the left limiting plate 26 is located on one side of the left side plate 24 along the length direction of the crossbeam 10, and the left limiting plate 26 and the left side plate 24 are both located in the positioning groove 101.

[0060] For example, both the right limiting plate 25 and the left limiting plate 26 include a transverse limiting plate and a longitudinal limiting plate (along the length of the crossbeam 10, the longitudinal limiting plate of the right limiting plate 25 is located on the side of the right side plate 23 near the left side plate 24, and is spaced apart from the right side plate 23; the longitudinal limiting plate of the left limiting plate 26 is located on the side of the left side plate 24 near the right side plate 23, and is spaced apart from the left side plate 24). The transverse limiting plate and the longitudinal limiting plate are connected to form an "L"-shaped right limiting plate 25 or left limiting plate 26. The transverse limiting plate is used to radially limit the first roller 51 or the second roller 52, the longitudinal limiting plate of the right limiting plate 25 and the right side plate 23 are used to limit the first roller 51 on both sides of the axial direction, respectively, and the longitudinal limiting plate of the left limiting plate 26 and the left side plate 24 are used to limit the second roller 52 on both sides of the axial direction, respectively.

[0061] For example, the right limiting plate 25 is fixed to the middle of the inner wall of the right side plate 23 by laser welding or riveting, while the left limiting plate 26 is fixed to the top of the inner wall of the left side plate 24. The two are arranged in a mirror symmetrical manner in the slide groove 201 and are parallel to each other. Their distance is slightly greater than the width of the connecting section 12 (usually 0.4–1.0 mm larger), ensuring that the connecting section 12 can be embedded below the right limiting plate 25 and the left limiting plate 26 without interference.

[0062] It should be understood that by constraining the movement boundaries of the first roller 51 and the second roller 52 by the right limiting plate 25 and the left limiting plate 26, when the crossbeam 10 moves along the arc-shaped slide rail 20, the connecting section 12 is stably constrained between the right limiting plate 25 and the left limiting plate 26. The first roller 51 always rolls in the space enclosed by the right limiting plate 25 and the bottom plate 22, and the second roller 52 rolls synchronously in the space enclosed by the left limiting plate 26 and the bottom plate 22. Ultimately, this prevents the first roller 51 and the second roller 52 from experiencing large-scale lateral slippage or lifting, thereby fundamentally suppressing the guiding instability induced by changes in track curvature, motor start-stop impact, or vehicle body vibration, and ensuring that the brush 40 and the electric rail 30 maintain constant contact pressure and good conductivity throughout the entire stroke.

[0063] The bottom surface of the connecting section 12 is provided with a connecting groove 102, which extends through the end face of the connecting section 12 along the length direction of the slide rail 20 and is located in the slide groove 201; the transmission component 70 passes through the slide groove 201 and the connecting groove 102 along the length direction of the slide rail 20 and is connected to the connecting section 12; the drive motor 60 is connected to the transmission component 70.

[0064] For example, the connecting groove 102 is a through groove structure formed at the bottom of the connecting section 12, which extends through the front end and rear end face of the connecting section 12 along the length direction of the slide rail 20, so that the external transmission component 70 can be directly inserted into and embedded in the groove from the end of the connecting section 12.

[0065] Optionally, the cross-section of the connecting groove 102 can be rectangular, trapezoidal, or polygonal, specifically a rectangular structure that matches the shape of the transmission component 70, in order to achieve circumferential limiting and torsional transmission.

[0066] For example, the depth and width of the connecting groove 102 are designed to fit the dimensions of the mating transmission component 70, ensuring sufficient contact area and shear bearing capacity during transmission. Optionally, the depth is 3mm to 10mm and the width is 4mm to 12mm.

[0067] For example, the connecting groove 102 is made by metal processing techniques such as milling, stamping or extrusion.

[0068] For example, the transmission component 70 is a conveyor belt used to transmit driving force from the drive motor 60 to the connecting section 12 of the crossbeam 10, thereby driving the crossbeam 10 and its connected components to reciprocate within the slide groove 201.

[0069] It should be understood that by setting the connecting groove 102 and embedding the transmission component 70 into the connecting groove 102, a transmission connection mechanism that is compact, reliable, and easy to assemble between the drive component and the crossbeam 10 is achieved, solving the problems of easy loosening and difficult assembly of traditional external connections; at the same time, the connecting groove 102 is located inside the slide groove 201, so that the transmission component 70 is guided by the slide rail 20 structure throughout the entire stroke, effectively suppressing vibration and offset phenomena during the movement.

[0070] Combination Figure 3 and Figure 4 As shown, the base plate 22 is provided with a through hole 202, which is spaced apart from the slide groove 201. The through hole 202 passes through the end face of the base plate 22 along the length of the slide rail 20. The conveyor belt passes through the through hole 202 and the slide groove 201.

[0071] In this embodiment, as Figure 4 As shown, the base plate 22 includes a lower base plate 221, an upper base plate 222, a left base plate 223, and a right base plate 224 that form a through hole 202.

[0072] For example, the conveyor belt is a ring-shaped conveyor belt, which is fitted inside the through hole 202 and the chute 201, and passes through... Figure 2 The belt separator 80 separates the upper and lower layers of the conveyor belt, preventing it from contacting the walls of the through hole 202 and the groove 201. One end of the conveyor belt is fitted onto a gear, and the drive motor 60 is connected to the gear transmission. The connecting section 12 is fixedly connected to the conveyor belt located in the groove 201. When the drive motor 60 starts, it drives the conveyor belt to reciprocate along the length of the slide rail 20, thereby pulling the crossbeam 10 to slide synchronously within the groove 201.

[0073] Optionally, the conveyor belt can adopt a polyurethane-coated steel cable core structure (PU+steel cable core), which ensures both transmission efficiency and excellent wear resistance.

[0074] It should be understood that by setting the through hole 202, the lower part of the conveyor belt is placed inside the through hole 202, avoiding the space congestion problem caused by the entire conveyor belt being located directly in the chute 201. Furthermore, because the conveyor belt has a flexible structure, it adapts to the geometry of the curved track, resulting in quiet and stable operation. At the same time, the drive motor 60 can be externally mounted outside the slide rail 20 body, facilitating heat dissipation and maintenance, reducing local load, and extending the system's service life.

[0075] Combination Figure 6 As shown, the brush 40 includes a first conductive section 41, a second conductive section 42, and a third conductive section 43 arranged sequentially along the length of the slide rail 20. The first conductive section 41 is connected to the crossbeam 10. A deformation gap is provided between the second conductive section 42 and the crossbeam 10. One end of the second conductive section 42 is conductively connected to the first conductive section 41, and the other end of the second conductive section 42 is inclined upward toward the connecting section 12. One end of the third conductive section 43 is conductively connected to the second conductive section 42, and the other end of the third conductive section 43 is inclined downward toward the connecting section 12. The connection between the second conductive section 42 and the third conductive section 43 is used for conductive connection with the electric rail 30.

[0076] For example, the first conductive segment 41 is the fixed segment of the brush 40. One end of it is rigidly connected to the designated mounting position of the connecting segment 12 of the crossbeam 10 by means of screws, rivets or integral molding, and the other end extends along the length of the crossbeam 10 and serves as the support base of the second conductive segment 42.

[0077] Optionally, the first conductive segment 41 may be made of a copper alloy with high conductivity and good mechanical strength, with a thickness of 0.8–1.5 mm and a width of 3–6 mm, in order to balance current carrying capacity and bending stiffness.

[0078] For example, the deformation gap provided between the second conductive section 42 and the connecting section 12 of the crossbeam 10 is used to provide clearance space for the deformation of the brush 40.

[0079] For example, with one end of the second conductive segment 42 inclined upwards towards the connecting segment 12 and one end of the third conductive segment 43 inclined downwards towards the connecting segment 12, the second conductive segment 42 and the third conductive segment 43 can form an approximately inverted "V" or inverted "U" shaped structure. The connection between the second conductive segment 42 and the third conductive segment 43 is rounded to prevent the connection from being sharp, thus preventing the brush 40 from scratching the rail 30 when it comes into contact with it.

[0080] It should be understood that the brush 40 can elastically abut against the rail 30 through elastic preload. This allows the crossbeam 10 to slide smoothly. If the overall height of the brush 40 increases slightly with the connecting section 12, the brush 40 can undergo flexible deformation within the elastic space provided by the deformation gap. This ensures that the brush 40 maintains contact with the rail 30 without causing the rail 30 to jam. Alternatively, if the overall height of the brush 40 decreases slightly with the connecting section 12, the rebound force of the second conductive section 42 and the third conductive section 43 can tighten the rail 30, maintaining contact between the brush 40 and the rail 30. Furthermore, because the second conductive section 42 is inclined upwards and the third conductive section 43 is inclined downwards, and the brush 40 contacts the rail 30 at the connection point of the second and third conductive sections 42, the contact area between the brush 40 and the rail 30 is reduced, preventing interference with the sliding of the crossbeam 10.

[0081] Combination Figure 1 As shown, the ceiling slide rail 20 includes two slide rails 20, two electric rails 30 and two brushes 40. The two slide rails 20 are symmetrically arranged along the center of the crossbeam 10. The two electric rails 30 are connected one-to-one to the slide grooves 201 of the two slide rails 20. The two brushes 40 are connected one-to-one to both ends of the crossbeam 10 and are electrically connected to the two electric rails 30.

[0082] For example, two electrical rails 30 are fixed inside the grooves 201 of the corresponding slide rails 20. They are usually made of copper alloy or tin-plated copper strip material, which has low resistivity and high wear resistance. Their cross-sectional shape can be designed as rectangular, trapezoidal or irregular structure with protruding ridges to enhance the contact stability with the brush 40. The electrical rails 30 are arranged to extend along the entire length of the slide rail 20 to ensure that the crossbeam 10 can draw power when sliding in any position.

[0083] Furthermore, two brushes 40 are respectively installed at both ends of the crossbeam 10 to form sliding electrical contact with the corresponding rails 30. The main body of the brush 40 can be made of elastic metal sheet (such as phosphor bronze or beryllium copper) and has a certain preload, so that it always adheres to the surface of the rail 30 during sliding and can maintain reliable conduction even under vibration or acceleration conditions.

[0084] Furthermore, the two slide rails 20 are mirror-symmetrically distributed with respect to the geometric center of the crossbeam 10, so that the supporting force and guiding force on the crossbeam 10 during the sliding process are evenly distributed on both sides, effectively suppressing the deflection torque caused by the difference in friction on one side, and significantly improving the stability of the movement.

[0085] Furthermore, the two brushes 40 and the two rails 30 form a parallel power supply circuit to share the load current and slow down the aging of the contact surface. More importantly, the structure has fault tolerance capability. If one brush 40 has poor contact due to contamination, wear or momentary detachment, the other side can still maintain basic power transmission, avoiding complete functional failure and improving the safety redundancy and durability of the system.

[0086] Correspondingly, the crossbeam 10 includes two connecting sections 12, which are located at both ends of the main beam section 11 along the length of the crossbeam 10. The two connecting sections 12 have the same structure, and their cooperation with the two slide rails 20 and their working principle are also the same. Further details will not be provided here.

[0087] It should be understood that by setting up symmetrically arranged slide rails 20 on both sides, the problems of unstable movement, uneven load jamming due to unilateral force, and contact failure risk of a single power supply path are solved when the existing vehicle roof slide rails 20 are carrying long or heavy crossbeams 10.

[0088] This embodiment also provides a vehicle, including the aforementioned vehicle slide rail assembly.

[0089] In summary, when the vehicle is parked or in motion, the user can trigger the roof rail 20 system via the central control screen, voice command, or mobile APP to drive the crossbeam 10 to move smoothly along a preset arc path to a designated position (such as above the rear passengers). At this time, the brush 40 is in continuous contact with the rail 30, and can then supply power to the installed modular equipment (such as retractable reading lights, binocular driver monitoring cameras, and micro projection modules) in real time and transmit control signals synchronously through the power input interface electrically connected to the brush 40.
