When the upper rail assembly is applied to the sliding rail, the upper rail body is located in the lower rail of the sliding rail, and the rib plate and the connecting support penetrate through the opening of the lower rail and stretch out of the lower rail. Therefore, the overlapping area of the upper rail assembly and the shielding decoration strip is mainly concentrated on the rib plate, the width of the opening of the upper rail assembly is mainly the thickness of the rib plate, and the thickness of the rib plate is small, so that the deformation angle and the deformation quantity of the shielding decoration strip in the overlapping area are small, and compared with the prior art, the sliding rail assembly can be quickly restored, and the attractiveness of the sliding rail assembly is improved. Foreign matters are not easy to fall into the slide rail even if falling.

Description

Technical Field

[0001] The present application relates to the technical field of vehicle seats, and in particular to a seat assembly, an electric slide rail, and a slide rail assembly. Background Art

[0002] Currently, in the slide rail assembly used in multi-purpose vehicles, the upper end of the upper rail assembly is long and wide, resulting in a long overlap area between the shielding strip and the upper rail assembly. This results in a long deformation area for the first shielding portion. This prolonged and significant deformation can easily cause the shielding strip to not reset. Even after the upper rail assembly has moved, the shielding strip still exhibits a certain amount of deformation, resulting in inconsistent deformation along the length of the slide rail assembly. This unevenness affects the aesthetics of the slide rail assembly, further compromising the functional properties of the shielding strip and making it easy for foreign matter to fall into the slide rail.

[0003] Therefore, how to improve the overall aesthetics of the slide rail assembly and reduce the risk of foreign matter falling into the slide rail assembly has become a technical problem that needs to be urgently solved by those skilled in the art. Utility Model Content

[0004] The present application proposes a seat assembly, an electric slide rail, and a slide rail assembly to enhance the overall aesthetics of the slide rail assembly and reduce the risk of foreign matter falling into the slide rail assembly.

[0005] In order to achieve the above objectives, this application discloses the following technical solutions:

[0006] In the first aspect, the present application provides a slide rail assembly, comprising an upper rail assembly, a lower rail and a shielding trim assembly, the upper rail assembly being connected to the seat and slidably arranged inside the lower rail, the upper rail assembly extending out of the lower rail through an opening; the shielding trim assembly comprising a shielding trim, which is arranged at the opening of the lower rail; the lower rail has an opening for accommodating the extension of the upper rail assembly and is connected to the vehicle body; the upper rail assembly comprises an upper rail body, a rib plate and a connecting bracket for mounting a gear box, the upper rail body and the rib plate both extend along the length direction of the upper rail assembly; the rib plate and the connecting bracket are both connected to the upper surface of the upper rail body; the rib plate is connected to one side of the connecting bracket, and the length of the rib plate is greater than the length of the connecting bracket.

[0007] In some examples, there are two ribs, namely a first rib and a second rib, which are located on both sides of the connecting bracket.

[0008] In some examples, the upper rail assembly further includes a connector provided on the rib plate for connecting to the seat, the connector provided on the first rib plate is the first connector, and the connector provided on the second rib plate is the second connector.

[0009] In some examples, the connecting bracket includes two side panels, a rear panel, and a top panel, wherein the two side panels and the rear panel extend upward from the upper rail body, the top panel connects the tops of the two side panels and the rear panel, the two side panels are arranged opposite to each other, and the two side panels, the rear panel, and the top panel form an installation space for installing the gearbox.

[0010] In some examples, a reinforcement is further provided on the lower surface of the upper rail body. The reinforcement is a U-shaped structure, including a first reinforcement, a second reinforcement and a third reinforcement connected to each other. The first reinforcement and the third reinforcement are arranged opposite to each other and are separated at the power output end of the gearbox.

[0011] In some examples, the lower surface of the upper rail body further includes two oppositely arranged first mounting members, the first mounting members are U-shaped members, and both sides of the first reinforcement member and the third reinforcement member are welded to the first mounting members, thereby further improving the rigidity of this area.

[0012] On the second aspect, the present application provides an electric slide rail, including a slide rail assembly, a gear box, a motor and a screw rod, wherein the gear box is arranged in a connecting bracket of the upper rail assembly; the motor is connected to the connecting bracket through a cross beam and is connected to the gear box for transmission; the screw rod is fixed inside the lower rail and is connected to the gear box for transmission.

[0013] In some examples, the ends of the upper rail assembly are equipped with pressing blocks for pressing the shielding trim strip.

[0014] In some examples, the shielding trim assembly also includes a zipper located below the shielding trim, with both sides of the zipper fixed to the shielding trim. The zipper is a double-headed zipper, with both ends of the zipper respectively fixed to the ends of the lower rail, and the pull head of the zipper fixed to the upper rail assembly.

[0015] In a third aspect, the present application provides a seat assembly, comprising a seat and an electric slide rail as described above, wherein the seat is connected to an upper rail of the electric slide rail.

[0016] As can be seen from the above technical solution, when the upper rail assembly of the present application is applied to a slide rail, the upper rail body is located inside the lower rail of the slide rail, and the rib plate and connecting bracket pass through the opening of the lower rail and extend out of the lower rail. As a result, the overlapping area between the upper rail assembly and the shielding trim assembly is mainly concentrated on the rib plate, and the width of the upper rail assembly at the opening is mainly the thickness of the rib plate. Due to the small thickness of the rib plate, the deformation angle and deformation amount of the shielding trim assembly in the overlapping area are both small. Compared with the existing technology, it can be quickly restored, and the shielding trim assembly tends to be flat in the length direction, thereby improving the aesthetics of the slide rail assembly. Even if foreign objects fall, they are unlikely to fall into the slide rail. BRIEF DESCRIPTION OF THE DRAWINGS

[0037] The application will be further described below in conjunction with the drawings and examples. It can be understood that the specific examples described herein are only used to explain the related application, and are not a limitation on the application. The described examples are only a part of the examples of the application, not all examples. Based on the examples in the application, all other examples obtained by those of ordinary skill in the art without creative labor are within the scope of protection of the application.

[0038] In a multi-purpose vehicle (MPV), the second-row seat has a long travel, and the slide rail of the second-row seat is usually a long slide rail. According to the driving form, the slide rail is divided into a manual slide rail and an electric slide rail.

[0039] Referring to Figure 1The electric slide shown in the figure includes a slide rail assembly 10, a transmission mechanism 20, a locking mechanism 30 and two motors 40, wherein the slide rail assembly 10 includes an upper rail component 11, a lower rail 12 and a shielding decorative strip 13, the upper rail component 11 is connected to the seat and is slidably arranged inside the lower rail 12; the part of the upper rail component 11 located inside the lower rail 12 can be understood as the lower end, and the part of the upper rail component 11 extending out of the lower rail 12 through the opening 1233 can be understood as the upper end; the shielding decorative strip 13 is arranged at the opening 1233 of the lower rail 12 to prevent foreign objects from falling; the lower rail 12 has an opening 1233 for accommodating the extension of the upper rail component 11 and is connected to the vehicle body; the transmission mechanism 20 and the locking mechanism 30 are both arranged on the upper rail component 11; one motor 40 is transmission-connected to the transmission mechanism 20 to realize the position adjustment of the upper rail component 11 relative to the lower rail 12 in the longitudinal direction, and the other motor 40 is transmission-connected to the locking mechanism 30 to realize the unlocking and locking of the upper rail component 11 relative to the lower rail 12.

[0040] The slide rail assembly 10 has a length direction X, a width direction Y and a height direction Z. The length direction X, the width direction Y and the height direction Z are perpendicular to each other, and the length direction X corresponds to the length of the slide rail assembly 10, the width direction Y corresponds to the width of the slide rail assembly 10, and the height direction Z corresponds to the height of the slide rail assembly 10.

[0041] See also Figure 2 and Figure 3 The upper rail assembly 11 includes a first side plate 111, a second side plate 112 and a blocking piece arranged relatively to each other, and the blocking piece blocks the two ends of the first side plate 111 and the second side plate 112 in the length direction; the transmission parts of the transmission mechanism 20 and the locking mechanism 30 are arranged in the area between the first side plate 111 and the second side plate 112.

[0042] The lower rail 12 includes a bottom wall 121, two top walls 123 and two side walls 122, wherein the bottom wall 121 is used to connect to the vehicle body floor; the two top walls 123 are arranged opposite to the bottom wall 121, and the two side walls 122 connect one end of the bottom wall 121 and the corresponding top wall 123; the top wall 123 includes a top edge 1231 extending from the side wall 122 to the center O of the lower rail 12 and a flange 1232 extending downward from the top edge 1231, and an opening 1233 for accommodating the upper rail assembly 11 is formed between the flanges 1232 of the two top walls 123.

[0043] The shielding trim 13 includes a shielding portion 131, an installation portion 132 and a clamp 133. The clamp 133 is clamped on the outer periphery of the lower rail 12, and the installation portion 132 extends from the middle of the shielding portion 131 in a direction away from the shielding portion 131; the installation portion 132 is inserted into the area between the clamp 133 and the lower rail 12 to achieve the installation of the shielding trim 13 on the lower rail 12; the shielding portion 131 includes a first shielding portion 1311 and a second shielding portion 1312. The first shielding portion 1311 extends from the installation portion 132 to the opening 1233, and the second shielding portion 1312 extends from the installation portion 132 to the side wall 122 of the lower rail 12.

[0044] When the upper rail assembly 11 moves relative to the lower rail 12, there is an overlapping area between the shielding trim 13 and the upper rail assembly 11. Within the overlapping area, the first shielding portion 1311 contacts the first side panel 111 or the second side panel 112 and is lifted up to deform. The deformation angle is a, which can be understood as the angle between the plane where the first shielding portion 1311 is located and the plane where the second shielding portion 1312 is located. The width L of the upper rail assembly 11 at the opening 1233 can be understood as the distance between the outer walls of the first side panel 111 and the second side panel 112 in the opening 1233 area. Under the premise that the length of the first shielding portion 1311 is constant, the deformation angle a is positively correlated with the width L, and the deformation angle a is positively correlated with the deformation amplitude of the shielding trim 13. Since the transmission parts of the transmission mechanism 20 and the locking mechanism 30 are arranged in the area between the first side plate 111 and the second side plate 112, the width L is not easy to be too small, so the deformation angle a of the first blocking portion 1311 is large and the deformation amplitude of the blocking trim strip 13 is large.

[0045] The upper end of the upper rail assembly 11 is relatively long, resulting in a longer overlap area between the shielding strip 13 and the upper rail assembly 11. This results in a longer deformation area for the first shielding portion 1311. This prolonged and significant deformation can easily cause the shielding strip 13 to not return to its original position. Even after the upper rail assembly 11 has moved, the shielding strip 13 may still be deformed to a certain extent, causing it to lose its functional properties and making it easy for foreign matter to fall into the slide rail assembly 10, affecting the overall aesthetics of the cabin.

[0046] In order to solve the above technical problems, the embodiments of the present application disclose a slide rail assembly, an electric slide rail and a seat assembly.

[0047] See also Figures 4 to 11 Some examples of the present application disclose a slide rail assembly 10, including an upper rail component 11, a lower rail 12 and a shielding trim component 130. The upper rail component 11 is connected to the seat and is slidably arranged inside the lower rail 12. The upper rail component 11 extends out of the lower rail 12 through an opening 1233; the shielding trim component 130 includes a shielding trim 13, which is arranged at the opening 1233 of the lower rail 12; the lower rail 12 has an opening 1233 to accommodate the extension of the upper rail component 11 and is connected to the vehicle body.

[0048] The upper rail assembly 11 includes an upper rail body 113, a rib plate 114 and a connecting bracket 115 for mounting the gear box 50. The upper rail body 113 and the rib plate 114 both extend in the length direction; the rib plate 114 and the connecting bracket 115 are both connected to the upper surface of the upper rail body 113; the rib plate 114 is connected to one side of the connecting bracket 115, and the length of the rib plate 114 is greater than the length of the connecting bracket 115.

[0049] When the upper rail assembly 11 in this example is applied to the slide rail assembly 10, Figure 6 As shown, the upper rail body 113 is located within the lower rail 12 of the slide rail assembly 10, while the rib 114 and connecting bracket 115 extend through the opening 1233 of the lower rail 12 and out of the lower rail 12. Therefore, the overlap between the upper rail assembly 11 and the obstruction trim 13 in this example is primarily concentrated on the rib 114. The width of the upper rail assembly 11 at the opening 1233 is primarily the thickness of the rib 114. Due to the relatively small width L of the rib 114, the deformation angle a and deformation amount of the obstruction trim 13 in the overlapped area are both smaller. Compared to the prior art, this allows for faster recovery, and the obstruction trim 13 tends to be flat along its length, thereby enhancing the aesthetics of the slide rail assembly. Furthermore, even if foreign objects are dropped, they are less likely to fall into the slide rail assembly 10.

[0050] The number of the aforementioned ribs 114 is one, while the figure shows two ribs 114, namely a first rib 1141 and a second rib 1142, which are located on both sides of the connecting bracket 115. This reinforces the connecting bracket 115 from both sides, making the force more even, thereby improving the connection strength of the connecting bracket 115. The first rib 1141 and the second rib 1142 are welded to both sides of the connecting bracket 115, and the first rib 1141 and the second rib 1142 are welded to the upper rail body 113 to reduce the use of fasteners. In some examples of the present application, the first rib 1141 and the second rib 1142 can also be connected to the upper rail body 113 and the connecting bracket 115 respectively by fasteners, which will not be described in detail here.

[0051] The upper rail assembly 11 in the present application can also be connected to the seat by providing a connecting member, which can be provided on the connecting bracket 115, or on the first rib 1141 and / or the second rib 1142. Taking the example of the connecting member provided on the first rib 1141 and the second rib 1142, the connecting member provided on the first rib 1141 is the first connecting member 1141a, and the connecting member provided on the second rib 1142 is the second connecting member 1142a.

[0052] In the length direction, the first connector 1141a is disposed at the top of the first rib 1141, away from the connecting bracket 115. The second connector 1142a is disposed at the top of the second rib 1142, away from the connecting bracket 115. In the length direction, the first connector 1141a, the first rib 1141, the connecting bracket 115, the second rib 1142, and the second connector 1142a are arranged in sequence. The first connector 1141a and the second connector 1142a are arranged at intervals for connecting the seat. The connection points between the seat and the upper rail assembly 11 are arranged at intervals, and the fixing points supporting the seat are arranged separately, thereby improving the stability of the supported seat.

[0053] The connecting bracket 115 is used to install the gear box 50, which transmits power to the upper rail assembly 11 to move relative to the lower rail 12. As long as the structure can achieve the installation of the gear box 50, it can be understood as the connecting bracket 115.

[0054] As shown in the figure, the connecting bracket 115 may include two side panels 1151, a rear panel 1153 and a top panel 1152. The two side panels 1151 and the rear panel 1153 extend upward from the upper rail body 113. The top panel 1152 connects the tops of the two side panels 1151 and the rear panel 1153. The two side panels 1151 are arranged opposite to each other. The two side panels 1151, the rear panel 1153 and the top panel 1152 form an installation space for installing the gear box 50. The installation space has an installation port to accommodate the installation and disassembly of the gear box 50.

[0055] The two side panels 1151, the rear panel 1153, and the top panel 1152 can be connected in a closed or open manner. A closed connection can be understood as a connection in which all parts are completely connected except for the mounting opening; an open connection can be understood as a connection in which the rear panel 1153 is not completely closed. Any connection is acceptable as long as the gearbox 50 can be stably mounted.

[0056] To connect the upper rail assembly 11 to the motor 40, in some examples of the present application, mounting ears 1151a may be provided on the connecting bracket 115 to mount the crossbeam supporting the motor 40. Specifically, the mounting ears 1151a are provided on the two side panels 1151. The two mounting ears 1151a extend along the length. In some examples, the mounting ears 1151a may also be arranged on the rib plate 114.

[0057] To improve the overall strength of the upper rail assembly 11, a reinforcement member 116 is further provided on the lower surface of the upper rail body 113 to increase the rigidity in the width direction of the upper rail body 113 and reduce the occurrence of deformation. Specifically, the reinforcement member 116 is a U-shaped structure, including a first reinforcement member 1161, a second reinforcement member 1162, and a third reinforcement member 1163 connected to each other. The first reinforcement member 1161 and the third reinforcement member 1163 are arranged opposite each other.

[0058] Since the power output end of the gear box 50 in the example of the present application is located at the lower part of the upper rail body 113 , the first reinforcement 1161 and the third reinforcement 1163 are arranged separately at the power output end of the gear box 50 .

[0059] The above-mentioned reinforcement 116 is directly welded to the lower surface of the upper rail body 113, or in some other examples of the present application, the lower surface of the upper rail body 113 also includes two relatively arranged first mounting members 1133, and the first mounting members 1133 are U-shaped members. The U-shaped members have better rigidity in the width direction, and the two sides of the first reinforcement 1161 and the third reinforcement 1163 are welded to the two first mounting members 1133, thereby further improving the rigidity of this area.

[0060] The upper rail body 113 is located inside the lower rail 12 and is used to support the entire upper rail assembly 11 . The upper rail body 113 may include a top plate 1131 , and the connecting bracket 115 and the rib plate 114 are disposed on the upper surface of the top plate 1131 .

[0061] In order to improve the rigidity of the upper rail body 113, the middle part of the top plate 1131 may also include flaps 1132 folded downward on both sides of the top plate 1131. The flaps 1132 cooperate with the top plate 1131 to improve the rigidity of the upper rail body 113 in the length direction.

[0062] In order to optimize the above technical solution, the upper rail body 113 includes limit plates 1134 at both ends in the length direction, which are folded downward and then upward from both sides of the top wall 123. The limit plates 1134 cooperate with the upper rail body 113 to form a groove, and the groove cooperates with the flange 1232 of the lower rail 12 to limit the left and right shaking of the upper rail assembly 11, thereby improving the stability of the upper rail assembly 11 during the movement relative to the lower rail 12.

[0063] Furthermore, the roller assembly 117 can also be installed in the area where the limit plate 1134 is set. For this purpose, a second mounting member 1135 can also be set here. The second mounting member 1135 is a U-shaped structural member. The second mounting member 1135 is fastened or welded to the limit plate 1134. The relative cantilever of the second mounting member 1135 is installed with a rotating shaft 1137. The roller assembly 117 is installed through the rotating shaft 1137 to reduce the friction during the movement of the upper rail assembly 11 relative to the lower rail 12.

[0064] Furthermore, the top plate 1131 is also provided with a third mounting member 1136 for mounting the guide wheel assembly. There are four third mounting members 1136. The third mounting members 1136 can realize the inclined installation of the guide wheel assembly to contact the top wall 123 of the lower rail 12, so that the upper rail assembly 11 can be subjected to force on all sides relative to the lower rail 12, thereby reducing the noise during the movement of the upper rail assembly 11.

[0065] To optimize the above solution, a pressure block 14 is mounted on the end of the upper rail assembly 11. The pressure block 14 can be connected to the upper rail assembly 11 using methods such as bayonet connection, bolt connection, and interference fit. The soft rubber pressure block 14 is located above the shielding trim 13 and can forcibly flatten the deformed shielding trim 13. Specifically, the pressure block 14 includes a connected pressing portion 141 and a clamping portion 142. The clamping portion 142 is clamped to the rib 114 of the upper rail assembly 11.

[0066] The shielding decorative strip 13 is fixed to the top of the lower rail 12 by means of a clamping member 133. A shielding decorative strip 13 is assembled on each side of the lower rail 12. After assembly, in the non-deformed area of ​​the decorative strip, the soft rubber of the left and right decorative strips is in a horizontal state. Due to the existence of assembly errors, there may be a slight gap. In some examples of the present application, the shielding decorative strip assembly 130 may also include a zipper 15. The zipper is a double-ended zipper, and the zipper 15 is located below the shielding decorative strip 13. The zipper 15 can be fixed below the shielding decorative strip 13 by sewing or other means. The two sides of the shielding decorative strip 13 are fixed to the shielding decorative strip 13. The two ends of the zipper 15 are respectively fixed to the ends of the lower rail 12, and the slider of the zipper 15 is fixed to the upper rail assembly 11. The zipper 15 opens and closes as the upper rail assembly 11 moves back and forth, which can further block the tiny opening 1233 of the covering trim 13 caused by assembly error, and then completely block the lower rail opening 1233, preventing any objects from entering the interior of the slide rail assembly and providing a better protective structure for the screw rod 60.

[0067] See also Figures 6 to 11 This application discloses an electric slide rail, comprising a slide rail assembly 10, a gear box 50, a motor 40, and a screw 60. The gear box 50 is disposed within a connecting bracket 115 of the upper rail assembly 11; the motor 40 is connected to the connecting bracket 115 via a crossbeam and is in transmission connection with the gear box 50; and the screw 60 is fixed within the lower rail 12 and in transmission connection with the gear box 50. Since the lower rail has the above-mentioned effects, an electric slide rail including the lower rail has corresponding effects, which will not be described in detail here.

[0068] In the above example of the present application, the screw rod 60 is fixed inside the lower rail 12, and the gear box 50 is fixed on the upper rail assembly 11. The screw rod 60 and the gear box 50 cooperate to form a spiral transmission structure with self-locking performance, which can realize both locking and transmission functions. The upper rail assembly 11 moves back and forth along the lower rail 12 along the screw rod 60 as the gear box 50 rolls. The shielding trim 13 deforms to an opening 1233 as the upper rail assembly 11 moves. The zipper 15 at the end of the upper rail assembly 11 opens and closes as the upper rail assembly 11 moves. At the same time, the soft rubber pressing block 14 at the end of the upper rail assembly 11 will quickly restore the locally deformed soft rubber to a horizontal state, so that the shielding trim 13 always remains in a horizontal state and is consistent with the parallelism of the ground. At the same time, the zipper 15 under the shielding trim 13 further blocks the gap caused by the size error of the shielding trim 13, making the overall appearance of the carpet surface of the cabin more beautiful.

[0069] The present application also discloses a seat assembly, comprising a seat and the electric slide as described above, wherein the seat is connected to the upper rail assembly 11 of the electric slide. Since the electric slide has the above effects, the seat assembly including the electric slide has corresponding effects, which will not be described in detail here.

[0070] The above description is merely a preferred embodiment of the present application and an illustration of the technical principles employed, and is not intended to limit the present application. For those skilled in the art, various modifications and variations of the present application are possible. The scope of application involved in the present application is not limited to the technical solutions formed by a specific combination of the above-mentioned technical features, but should also cover other technical solutions formed by any combination of the above-mentioned technical features or their equivalents without departing from the above-mentioned application concept. For example, a technical solution formed by replacing the above-mentioned features with (but not limited to) technical features with similar functions disclosed in this application.
