[0043] Vehicle seat rails are transitional structures connecting seats to the vehicle body structure. They bear the weight of the car seats and passengers and ensure that the seats can slide in a specified direction, thus requiring high reliability and safety. In related technologies, the seat moving parts within the grooves of the seat rails need to be lubricated. However, because the seats are frequently moved, the exposed portion of the rail grooves is often a C-shaped opening. This allows foreign objects and dust to easily enter when passengers place their feet in this position, affecting the rail's functional reliability. Furthermore, these openings can easily cause passengers wearing high heels to get their heels stuck in the rails, seriously threatening passenger safety.

[0044] This application provides a seat rail. Figure 1 This is a three-dimensional structural diagram of a seat guide rail according to an exemplary embodiment of this application. Figure 2 This is a schematic cross-sectional view of a seat guide rail according to an exemplary embodiment of this application, as shown below. Figure 1 , Figure 2 As shown, the seat guide rail 1 includes a guide rail body 11, a movable track 13, a protective cover 15, a protective shield 12, and a transmission mechanism 14. The guide rail body 11 encloses a track space 114. The first sidewall 111 of the guide rail body 11 has a track opening 112 connecting the inside and outside of the track space 114. The guide rail body 11 includes an outer side surface 1111 located outside the track space 114. The movable track 13 is movably assembled to the track opening 112, so that the track opening 112 forms an occupied section that matches the movable track 13 and an open section located outside the occupied section. The protective shield 12 is assembled to the outer side surface 1111, and an assembly gap 16 is provided between the protective shield 12 and the first sidewall 111. The transmission mechanism 14 is drively connected to the protective cover 15, so that the protective cover 15 extends and retracts within the assembly gap 16 and covers the open section as the movable track 13 moves.

[0045] The aforementioned seat rail 1 includes a protective cover 15 and a protective shield 12. The protective shield 12 is assembled to the outer side 1111 of the rail body 11, and an assembly gap 16 is provided between the protective shield 12 and the first side wall 111 of the rail body 11. The transmission mechanism 14 is connected to the protective cover 15, so that the protective cover 15 can extend and retract within the assembly gap 16 as the movable rail 13 moves, covering the open section of the rail opening 112. The protective cover 15 extends and retracts within the assembly gap 16 between the protective shield 12 and the rail body 11 to cover the open section, preventing the rail opening 112 from being exposed. Furthermore, the rail body 11 and the protective shield 12 provide support for the protective cover 15, improving the structural reliability of the protective cover 15.

[0046] The seat can be assembled with the movable track 13, and the seat moves accordingly as the movable track 13 moves relative to the track opening 112. During the movement of the seat, different sections of the movable track 13 and the track opening 112 cooperate. The track opening 112 that cooperates with the movable track 13 is occupied, while the track opening 112 that is not occupied by the movable track 13 forms an open section. The protective cover 15 covers the open section during its telescopic movement, preventing the track opening 112 from being exposed and allowing foreign objects to enter. Since the protective cover 15 telescopically extends within the assembly gap 16 between the protective cover 12 and the guide rail body 11, it not only increases the shielding effect of the open section, but also utilizes the protective cover 12 and the guide rail body 11 to form a structural support for the protective cover 15, preventing the protective cover 15 from being damaged by pressure or foreign objects from getting stuck.

[0047] The aforementioned guide rail body 11 encloses the track space, which not only accommodates the movable track 13 during its movement to improve the reliability of the movement of the movable track 13, but also enhances the structural strength of the guide rail body 11 by utilizing its own cavity structure. To further enhance the structural strength of the guide rail body 11, the guide rail body 11 may also include an extension portion 115 connected to the first side wall 111 and extending into the track space 114. The extension portion 115 is bent relative to the first side wall 111 and extends into the track space 114, which enhances the support effect of the first side wall 111 on the protective cover 15 and the protective shield 12, and also avoids occupying the external space of the guide rail body 11.

[0048] In some embodiments, the seat rail 1 further includes an auxiliary protective assembly 17. The protective cover 12 includes an inner surface facing the rail body 11 and an outer surface opposite to the inner surface. The auxiliary protective assembly 17 is assembled onto the outer surface. The auxiliary protective assembly 17 includes a first protective body and a second protective body. The first and second protective bodies are sealed together in a first state to cover the open section. In a second state, the first and second protective bodies are separated to allow the movable rail 13 to pass through. Further providing the auxiliary protective assembly 17 to the seat rail 1, utilizing the sealed engagement of the first and second protective bodies in the first state, can form another layer of coverage over the open section, helping to improve dust protection.

[0049] Figure 3 This is an exploded structural diagram of a seat guide rail 1 according to an exemplary embodiment of this application. Figure 4 This is a side view of a seat guide rail 1 according to an exemplary embodiment of this application. Figure 5 yes Figure 4 A schematic diagram of the cross-sectional structure at point AA is shown below. Figures 3-5 As shown, the auxiliary protective component 17 also includes a zipper latch 173 connected to the movable track 13. The first protective body includes a first zipper structure 171, and the second protective body includes a second zipper structure 172. The zipper latch 173 is assembled with the first zipper structure 171 and the second zipper structure 172 respectively, so that the first zipper structure 171 and the second zipper structure 172 engage and seal in a first state to cover the open section, and separate in a second state to allow the movable track 13 to pass through. During the movement of the movable track 13, the zipper latch 173 is pulled, and the first zipper structure 171 and the second zipper structure 172 can be engaged by the zipper latch 173 in the first state, and separate when the first zipper structure 171 and the second zipper structure 172 are acted upon in the opposite direction by the zipper latch 173. The above-mentioned zipper structure has good connection reliability and smooth engagement and disengagement, which helps to improve the user experience.

[0050] In the above embodiment, zipper latches 173 can be connected to both ends of the movable track 13. When the movable track 13 moves to the right along the dotted arrow, the zipper latch 173 on the left pulls the first zipper structure 171 and the second zipper structure 172 to engage, and the zipper latch 173 on the right pulls the first zipper structure 171 and the second zipper structure 172 to disengage.

[0051] In other embodiments, the first protective body includes a first adhesive strip, and the second protective body includes a second adhesive strip. The first and second adhesive strips are sealed together in a first state to cover the open section. In a second state, the first and second adhesive strips separate to allow the movable track 13 to pass through. The first and second adhesive strips can achieve a seal by abutting each other in the first state, and separate after being pushed by the movement of the movable track 13, allowing the movable track 13 to pass through. The above-mentioned adhesive strip configuration is low-cost, simple in structure, and easy to assemble.

[0052] In other embodiments, the first protective body can be a first brush, and the second protective body can be a second brush, with the first and second brushes interlacing to create a shielding effect. When the movable track 13 moves, the interlaced first and second brushes can be separated to allow passage.

[0053] In the above embodiment, the protective cover 15 can extend and retract within the assembly gap 16 and cover the open section as the movable track 13 moves. Specifically, in the width direction of the seat guide rail 1, the coverage of the open section by the protective cover 15 can be such that the width of the protective cover 15 is greater than or equal to the width of the track opening 112. For example, if the width of the protective cover 15 is greater than the width of the track opening 112 in the width direction of the seat guide rail 1, effective coverage of the track opening 112 can be achieved through the overlap of the protective cover 15 with the first sidewall 111 of the track body 11, improving the assembly reliability of the protective cover 15.

[0054] Figure 6 yes Figure 4 A schematic diagram of the cross-sectional structure at point BB is shown below. Figure 6 As shown, the transmission mechanism 14 includes a winding mechanism 142, and the protective cover 15 is made of a flexible material. The protective cover 15 is connected to both the winding mechanism 142 and the movable track 13, so that it can be wound into or extend from the winding mechanism 142 as the movable track 13 moves. During the movement, the movable track 13 pulls the protective cover 15 to extend and retract, and the extension and retraction of the protective cover 15 are realized by the transmission mechanism 14, which facilitates the extension and retraction of the protective cover 15.

[0055] The aforementioned coiling mechanism 142 can be a spiral spring. The spiral spring can be stretched and deformed when the movable track 13 pulls the protective cover 15, causing the protective cover 15 to extend. It can also be elastically retracted when the movable track 13 moves in the opposite direction, so as to pull the protective cover 15 back and coil it on the spiral spring.

[0056] Alternatively, the aforementioned curling mechanism 142 may also include a motor and a curling shaft, with the curling shaft connected to the output end of the motor. When the movable track 13 moves to the left along the dotted arrow, the motor can drive the protective cover 15 located on the left side of the movable track 13 to curl and retract, and the protective cover 15 located on the right side of the movable track 13 to stretch to cover the open section.

[0057] Furthermore, the aforementioned curling mechanism 142 may also include a housing 141, which can be housed within the housing 141 when the protective cover 15 is curled back, thereby improving the aesthetics of the seat guide rail 1 and reducing structural interference between the curling mechanism 142 and external components.

[0058] In the above embodiments, the seat guide rail 1 may include a first body 151 located on one side of the movable track 13 and a second body 152 located on the other side of the movable track 13. The first body 151 and the second body 152 may make opposite contraction movements as the movable track 13 moves.

[0059] The aforementioned seat rail 1 may include a pair of transmission mechanisms 14, which are located at both ends of the rail body 11 in the rail extension direction, so as to optimize the transmission stability and reliability of the transmission mechanism 14 to the protective cover 15.

[0060] In other embodiments, the transmission mechanism 14 may include a roller mechanism, and the protective cover 15 may be made of a flexible material. The protective cover 15 is connected to both ends of the movable track 13 in the direction of movement, and the protective cover 15 rolls in cooperation with the rollers of the roller mechanism to transmit power relative to the rollers as the movable track 13 moves. The aforementioned roller mechanism helps to simplify the transmission structure of the protective cover 15 and improve transmission reliability. The aforementioned roller mechanism may be disposed at both ends or below the guide rail body 11, and this application does not limit the placement of the roller mechanism.

[0061] In the direction of track extension, the guide rail body 11 includes two ends. When the transmission mechanism 14 is located at both ends of the guide rail body 11, the transmission mechanism 14 can be located on the outer side of the ends of the guide rail body 11 to avoid occupying the track length. For example, the transmission mechanism 14 can be assembled to the outer end of the track of the guide rail body 11 to avoid occupying the track. Alternatively, the transmission mechanism 14 can also be assembled to the vehicle body to further reduce the structural impact of the transmission mechanism 14 on the seat guide rail 1.

[0062] It should be noted that the protective cover 15 is made of steel, utilizing the rigidity and rollability of steel to improve the structural strength and storage convenience of the protective cover 15. Alternatively, the protective cover 15 can also be made of other rigid materials. When the protective cover 15 is made of steel, it can be a steel sheet to improve the ease of rolling and storage.

[0063] In some embodiments, the protective cover 12 includes a first portion 121 and a second portion 122 connected to and bent relative to the first portion 121. An assembly gap 16 is formed between the first portion 121 and a first sidewall 111, and the second portion 122 is assembled to the guide rail body 11. The first portion 121 of the protective cover 12 can be used to form the assembly gap 16 between itself and the first sidewall of the guide rail body 11, and to support the protective cover 15. The second portion 122 of the protective cover 12 can be used to achieve a fixed assembly with the guide rail body 11 and to strengthen the structural strength of the guide rail body 11.

[0064] For example, the protective cover 12 includes a first part 121 and a second part 122 connected to the first part 121 and bent relative to the first part 121, the guide rail body 11 includes a second side wall 113 bent relative to the first side wall 111, an assembly gap 16 is formed between the first part 121 and the first side wall 111, and the second part 122 is assembled to the second side wall 113.

[0065] Alternatively, an assembly gap 16 is formed between the first part 121 and the first sidewall 111, and the second part 122 is bent below the first part 121 relative to the first part 121 and assembled to the first sidewall 111.

[0066] In some embodiments, the protective cover 12 avoids the track opening 112 to prevent structural interference of the protective cover 12 with the movable track 13. Alternatively, the protective cover 12 includes an extension section that covers part of the track opening 112, thereby increasing the support effect of the protective cover 15 while ensuring that the protective cover 12 does not affect the movement of the movable track 13.

[0067] In the above embodiments, the protective cover 12 can be made of a rigid material to enhance its support strength for the protective cover 15. Alternatively, the protective cover 12 can also be made of other rigid materials.

[0068] In some embodiments, the seat rail 1 may include a pair of protective covers 12. The first sidewall 111 includes a first section located on one side of the rail opening 112 and a second section located on the other side of the rail opening 112. One protective cover 12 is fitted into the first section, and the other protective cover 12 is fitted into the second section. The two protective covers 12 cooperate to provide appropriate clearance from the rail opening 112, while also ensuring the structural reinforcement effect of the protective cover 12 on the protective cover 15, and improving the ease of assembly between the protective cover 12 and the rail body 11.

[0069] This application further provides a vehicle that includes the aforementioned seat rail 1.

[0070] The aforementioned seat rail 1 includes a protective cover 15 and a protective shield 12. The protective shield 12 is assembled to the outer side 1111 of the rail body 11, and an assembly gap 16 is provided between the protective shield 12 and the first side wall 111 of the rail body 11. The transmission mechanism 14 is connected to the protective cover 15, so that the protective cover 15 can extend and retract within the assembly gap 16 as the movable rail 13 moves, covering the open section of the rail opening 112. The protective cover 15 extends and retracts within the assembly gap 16 between the protective shield 12 and the rail body 11 to cover the open section, preventing the rail opening 112 from being exposed. Furthermore, the rail body 11 and the protective shield 12 provide support for the protective cover 15, improving the structural reliability of the protective cover 15.

[0071] It should be noted that the aforementioned vehicles can be buses, ambulances, trucks, vans, commercial vehicles, private cars, etc., and this application does not impose any restrictions on this.

[0072] It should be noted that the technical solutions or features described in the above embodiments can be combined or supplemented with each other without conflict. The scope of protection of this application is not limited to the precise structures described in the above embodiments and shown in the accompanying drawings; all modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the scope of protection of this application.
