Description

Technical Field

[0001] This disclosure relates to the field of transportation technology, and more specifically to a slide rail device, a combined slide rail assembly for a transportation vehicle, an interior trim assembly for a transportation vehicle, and a transportation vehicle. Background Technology

[0002] Large SUVs and MPVs typically feature three rows of seats, with the first and second rows requiring forward and backward movement. Existing technologies offer corresponding solutions for this usage scenario.

[0003] In conventional seat sliding rails, two lower sliding rails are typically used for each row of seats. In a traditional design, each lower sliding rail contains a long lead screw, which simultaneously supports the sliding of both the front and rear seats. This means each lead screw must bear the load from two seats, requiring high strength. Additionally, in another traditional design, each seat is connected to two upper sliding rail components, each driven by a corresponding motor. Because the gap between the two sets of sliding rails is relatively large in this traditional design, when the two upper sliding rail components corresponding to the same seat are driven by two independent motors, a synchronization module is needed to ensure the synchronicity of the left and right motors and the upper sliding rails. Otherwise, there is a risk of malfunction or jamming, leading to high system costs.

[0004] Furthermore, traditional seat rails only consider the seat's application scenario and do not take into account other application possibilities. One reason for this problem is that traditional seat rails typically use a "copy" approach to design the upper and lower rails and their corresponding drive mechanisms. The conventional approach is to first design a lower rail, arrange the travel structure (such as a lead screw) and upper rail components for this lower rail, and then set up the drive mechanism for the upper rail components. Finally, the overall layout for this one lower rail is applied to another lower rail. This approach is mainly limited by the need to set up two parallel upper rail components for a seat to ensure the seat's stability. Since there are two parallel upper rail components for a seat, two parallel lower rails need to be set up for these two upper rail components. In this case, for the sake of motion synchronization, using a "copy" approach to apply one layout to both lower rails and their related upper rail components and drive mechanisms is the most intuitive. However, this "copy" approach also has limitations, such as limitations in the layout of the travel section.

[0005] Other existing seat rails also generally suffer from the aforementioned limitations in the layout of the travel section, the need to set up a motor for each upper rail component, and the limited application scenarios. Utility Model Content

[0006] The purpose of this disclosure is to provide a slide rail device that overcomes the technical problem of limited layout of the travel section of the upper slide rail component due to the "copying" mentality.

[0007] Another object of this disclosure is to provide a combined slide rail assembly for a vehicle, an interior trim assembly for a vehicle, and a vehicle.

[0008] To achieve the aforementioned objective, a first aspect of this disclosure relates to a slide rail device, characterized in that the slide rail device includes at least two lower slide rails arranged side by side and at least two upper slide rail assemblies movable at the lower slide rails and arranged sequentially along the axial direction of the lower slide rails, wherein each upper slide rail assembly is provided with a travel portion for its own use only and coupled to the corresponding upper slide rail assembly, and each travel portion is configured to limit the travel distance of the coupled upper slide rail assembly, the travel portion being disposed at the lower slide rail, wherein each travel portion is constructed and arranged such that there is at least an overlap between the travel distances defined by the travel portions for different upper slide rail assemblies, and the arrangement structure of the travel portions at at least the two lower slide rails is different.

[0009] In this disclosure, by inventively constructing and arranging the stroke portions such that there is an overlap between the travel strokes defined by the stroke portions for different upper slide rail assemblies, and that the arrangement of the stroke portions at at least the two lower slide rails is different, the limitations of the stroke portion layout for upper slide rail components in the prior art can be overcome. In the prior art, due to the two lower slide rails and their mating upper slide rail components and lead screw structures, in order to achieve the synchronous movement of the seat on the upper slide rail components, the lower slide rails, upper slide rail components, and lead screw structures are usually arranged symmetrically with each other. This symmetrical arrangement leads to a technician designing based on one lower slide rail and its mating components, and then directly replicating this design on the other lower slide rail and its mating components. This disclosure breaks free from the constraints of conventional thinking and creatively proposes that the travel distance defined by the travel portions of two different upper slide rail assemblies can overlap, and that the arrangement of the travel portions at least at the two lower slide rails is different. This overcomes the limitations of the single-slide rail approach in terms of travel portion layout for different upper slide rail assemblies, thereby providing possibilities for a wider range of movement forms and driving applications. Under the traditional "copy" design concept, one might consider using virtual stops generated by a controller to partially overcome the travel distance limitation. However, such virtual stops, generated by a controller, are considered insufficiently robust or stable in engineering practice, lacking "inherent safety." Under the "copy" concept, if "inherently safe" physical stops are to be used, the existence of the mechanical structure prevents overlap of the travel portions. This disclosure breaks through the traditional "copy" design concept and creatively proposes a travel portion arrangement based on a "heterogeneous" approach, ensuring that there is overlap between the travel distances defined by the travel portions of at least two different upper slide rail assemblies, and that the arrangement of the travel portions at at least the two lower slide rails is different. Therefore, it is possible to achieve overlapping of travel distances using physical stops. This enables an inherently safe overlapping arrangement structure, which is more robust than the overlapping travel distance scheme based on virtual stops that might be used under the "replication" concept mentioned earlier.

[0010] In this disclosure, a "stroke section" can be understood as a structure that defines a travel distance. It can be formed, for example, by a stroke element constructed as a lead screw or rack, as described below, or by a portion of a sliding rail. For example, the lead screw, rack, or sliding rail can be used with a stop point to define the stroke section. It should also be noted that a single stroke element can form only one stroke section, or multiple stroke sections can be formed, for example, with a virtual stop point. "Arrangement structure of the stroke section" can be understood as the arrangement, layout, or extension structure of the stroke section along the sliding rail. "At least two sliding rails" can be understood as the presence of two or more sliding rails, for example, three, four, or five sliding rails, and so on. Furthermore, "the arrangement structure of the stroke sections at at least two sliding rails is different from each other" means that, for at least two sliding rails, the arrangement of multiple stroke sections on each of the at least two sliding rails is different overall.

[0011] In some implementations, there is an overlap between the travel distances defined by different travel portions located at different lower rails and coupled to two adjacent upper slide rail assemblies.

[0012] In some embodiments, in each upper slide rail assembly, at least one upper slide rail assembly is equipped with only one travel portion, and there is an overlap between the travel distance defined by the travel portion for the at least one upper slide rail assembly and the travel distance defined by the travel portion for an adjacent upper slide rail assembly. Thus, unlike the prior art's "copying" concept, in this disclosure, at least one upper slide rail assembly can be equipped with only one travel portion, which is a more advantageous upper slide rail assembly-travel portion pairing relationship based on a "heterogeneous" approach.

[0013] In some implementations, each upper slide rail assembly is equipped with only one travel section. Thus, unlike the "copying" concept of the prior art, a one-to-one correspondence structure between the upper slide rail assembly and the travel section can be provided based on a "heterogeneous" approach, which provides an advantageous solution for the arrangement structure of the upper slide rail assembly and the travel section.

[0014] In some embodiments, the two stroke portions corresponding to any two adjacent upper slide rail assemblies are respectively arranged at the two lower slide rails. This allows for an advantageous arrangement of the upper slide rail assembly-stroke portions for any two adjacent upper slide rail assemblies.

[0015] In some implementations, each travel section is located at a different lower slide rail. Therefore, only one travel section can be provided at each lower slide rail, allowing full utilization of the available length of each lower slide rail, thereby significantly increasing the travel distance of the upper slide rail assembly.

[0016] In some embodiments, the travel strokes of the travel sections for any two adjacent upper slide rail assemblies overlap. This allows for an advantageous relative arrangement of the various travel sections in the longitudinal direction.

[0017] In some embodiments, the slide rail device includes a travel member disposed at the lower slide rail, the travel portion being formed by the travel member; or the travel portion being formed by a portion of the lower slide rail. When the travel portion is formed by the travel member, it provides the possibility of electric movement of the upper slide rail assembly; while when the travel portion is formed by a portion of the lower slide rail, it provides the possibility of manual movement of the upper slide rail assembly.

[0018] In some implementations, a single travel member forms only one travel section. Since a single travel member forms only one travel section, it can be used only to carry the load on the upper slide rail assembly that is matched with this single travel section, instead of carrying the load on, for example, two upper slide rail assemblies as in the prior art. Thus, the travel member does not have to bear a large load and can be designed, for example, with a small cross-sectional size, thereby saving costs.

[0019] In some embodiments, the travel portion is limited by a stop point, which is either a physical stop point set on the travel member or the lower slide rail, or the stop point is a virtual stop point set by a controller for the slide rail device along the travel member or the lower slide rail.

[0020] In some implementations, the positions of the abutments at at least two of the lower slide rails are different when viewed in the lateral direction. The travel portion is typically defined by these abutments. When the arrangement of the travel portions at at least two lower slide rails differs, the positions of the abutments for these travel portions are different from each other when viewed in the lateral direction of the lower slide rail. This contrasts with the prior art, which, due to its "copying" concept, has travel portions defined by the abutment positions at two lower slide rails overlapping each other when viewed in the lateral direction.

[0021] In some implementations, the number of lower slide rails is the same as the number of upper slide rail assemblies, or the number of lower slide rails is less than the number of upper slide rail assemblies.

[0022] In some embodiments, the upper slide rail assembly itself includes a first upper slide rail component and a second upper slide rail component, wherein the first upper slide rail component and the second upper slide rail component are respectively disposed at any two of the at least two lower slide rails.

[0023] In some embodiments, the first upper slide rail component and the second upper slide rail component are respectively disposed at the two outermost lower slide rails of the at least two lower slide rails. This maximizes the stable operation of the interior trim or other track devices fixed to the first and second upper slide rail components.

[0024] In some implementations, each upper slide rail assembly is equipped with only one driver, which works in conjunction with the travel section of the corresponding upper slide rail assembly to move each upper slide rail component of the corresponding upper slide rail assembly. Thus, each upper slide rail assembly can be moved using only one driver. Compared to the prior art where a separate motor is used for each of the two upper slide rail components in an upper slide rail assembly, no additional module is needed to control the synchronization of the various upper slide rail components within the same upper slide rail assembly, and the number of motors is reduced, thereby lowering costs.

[0025] In some embodiments, a first upper slide rail assembly-stroke section configuration is provided. In this configuration, one of the first and second upper slide rail components is positioned in a lower slide rail with a stroke section that mates with the corresponding upper slide rail assembly, while the other upper slide rail component is positioned in a lower slide rail without a corresponding stroke section. Thus, for a given upper slide rail assembly, one upper slide rail component can move on the corresponding lower slide rail via a driver and a stroke section that mates with the driver, while the other upper slide rail component can act as a driven rail. This eliminates the need for module control of the synchronization of the various upper slide rail components within the same upper slide rail assembly.

[0026] In some implementations, the driver is disposed on the upper slide rail component.

[0027] In some embodiments, a second upper slide rail assembly-stroke section configuration is provided. This configuration includes at least three lower slide rails, with the stroke section corresponding to each upper slide rail assembly located on the lower slide rail between the first and second upper slide rail components. Thus, both upper slide rail components can function as driven rails. This configuration also allows for synchronization of the various upper slide rail components within the same upper slide rail assembly without requiring a synchronization module for control.

[0028] In some embodiments, a third upper slide rail component is provided at the lower slide rail having a travel portion that mates with the corresponding upper slide rail assembly. The third upper slide rail component is located between the first upper slide rail component and the second upper slide rail component, and the driver is disposed on the third upper slide rail component. This achieves an advantageous arrangement of the driver for the second upper slide rail assembly-travel portion configuration.

[0029] In some embodiments, a support member is provided, which is horizontally mounted on each upper slide rail component in the same upper slide rail assembly to connect the upper slide rail components in the same upper slide rail assembly. This allows for synchronous operation of the upper slide rail components in the same upper slide rail assembly using a simple horizontally mounted support member.

[0030] In some embodiments, the actuator is mounted on the support member. This allows for another advantageous arrangement of the actuator for the second upper slide rail assembly – the travel section.

[0031] In some embodiments, the at least two lower slide rails are arranged relative to each other in the lateral direction such that a single driver can move all the upper slide rail components in the corresponding upper slide rail assembly without causing the corresponding upper slide rail assembly to jam at the lower slide rail or to experience asynchronous movement. The opening width of the lower slide rail affects the synchronization of the upper slide rail components when a single motor is used for two upper slide rail components (one-to-two). If the opening width is too large, such as when the opening width is about 400 mm in the prior art, a single motor is required to drive one upper slide rail component. Therefore, in this disclosure, by using the above-described arrangement of the lower slide rails relative to each other in the lateral direction, it is possible to ensure that jamming or asynchronous movement does not occur when using a single driver to move the corresponding upper slide rail assembly.

[0032] In some embodiments, at least some or all of the at least two sliding rails are arranged adjacent to each other. This ensures a small opening width for the sliding rails and eliminates the risk of malfunction or jamming.

[0033] In some implementations, the opening width of the at least two lower slide rails is at most five times the width of one lower slide rail. This ensures a smaller opening width for the lower slide rails and eliminates the risk of malfunction or jamming.

[0034] In some implementations, the opening width of the at least two lower slide rails is at most four times the width of one lower slide rail. This better ensures that the opening width of the lower slide rails is small, and thus eliminates the risk of inoperability or jamming.

[0035] In some implementations, the opening width of the at least two lower slide rails is at most three times the width of one lower slide rail. This ensures a particularly good small opening width for the lower slide rails, and thus eliminates the risk of inoperability or jamming.

[0036] In some implementations, at least some or all of the at least two lower slide rails are arranged adjacent to each other. This essentially ensures that the opening width of the lower slide rails is small, and thus eliminates the risk of inoperability or jamming.

[0037] In some embodiments, the at least two lower slide rails are integrally constructed and form a single lower slide rail assembly. This advantageously results in a lower slide rail assembly with a small opening width. With the integral construction, all adjacent lower slide rails can be directly adjacent to each other, thereby significantly reducing the opening width.

[0038] In some embodiments, the lower slide rail assembly is manufactured by integral extrusion molding. This allows for advantageous manufacturing of the lower slide rail assembly.

[0039] In some embodiments, the at least two sliding rails are each formed separately and, when joined together, form a sliding rail assembly through form-locking and / or material-locking and / or force-locking. Therefore, in addition to one-piece molding, it is conceivable to form them separately and then join them together. This combination method is more flexible than one-piece molding of multi-rail sliding rail assemblies. In this disclosure, form-locking can be understood as constraint through geometry, such as connection through snap-fit ​​or mortise-and-tenon structures. Material-locking can be understood as connection achieved through physical or chemical action of materials, such as welding or gluing. Force-locking connection can be understood as connection through friction or preload, such as bolted connections.

[0040] In some implementations, two adjacent lower rails are constructed as a groove and share a groove wall between the two lower rails.

[0041] In some implementations, at least three sliding rails are provided.

[0042] In some embodiments, the travel element is constructed as a lead screw or rack.

[0043] In some embodiments, the slide rail device is used in a transport vehicle.

[0044] A second aspect of this disclosure relates to a modular slide rail assembly for a transport vehicle, characterized in that the modular slide rail assembly includes a first slide rail device and a second slide rail device, the first slide rail device extending along the longitudinal direction of the transport vehicle, and the second slide rail device extending along the transverse direction of the transport vehicle and arranged on the first slide rail device and movable along the longitudinal direction of the transport vehicle via the first slide rail device, wherein the first slide rail device is a slide rail device according to this disclosure and / or the second slide rail device is a slide rail device according to this disclosure. Thus, a crisscrossing modular slide rail assembly can be realized, thereby enabling more diverse arrangement forms of the slide rail devices within the transport vehicle.

[0045] In some embodiments, two first slide rail devices are provided, arranged parallel to each other. This allows for a more stable arrangement of the second slide rail device on the first slide rail device. Furthermore, these two first slide rail devices can also be used, as commonly seen, for the forward and backward movement of interior trim components, such as seats.

[0046] A third aspect of this disclosure relates to an interior trim assembly for a vehicle, characterized in that the interior trim assembly includes interior trim and a slide rail device according to this disclosure or a combined slide rail assembly for a vehicle according to this disclosure, wherein the interior trim is mounted on a corresponding upper slide rail assembly of the slide rail device or on a corresponding upper slide rail assembly of the second slide rail device to enable movement.

[0047] In some embodiments, the slide rail device extends along the longitudinal direction of the transport vehicle; or the slide rail device extends along the transverse direction of the transport vehicle.

[0048] In some embodiments, the interior trim is a seat or a footrest or leg rest for supporting the occupant's feet or legs. Thus, unlike existing technologies, the interior trim is not limited to seats but can also be footrests or leg rests, providing a wider range of application scenarios for the corresponding sliding rail devices.

[0049] In some embodiments, the interior trim assembly includes a seat and a leg rest as interior trim components, wherein the upper slide rail assembly for the seat and the upper slide rail assembly for the leg rest are adjacent to each other front and rear, and there is an overlap between the travel distance defined by the travel portion of the upper slide rail assembly for the seat and the travel distance defined by the travel portion of the upper slide rail assembly for the leg rest. This provides a feasible movement scheme for applications combining a seat and a leg rest. There is currently no similar movement scheme specifically designed for applications where seats and leg rests are separately configured.

[0050] A fourth aspect of this disclosure relates to a means of transport comprising a slide rail device according to this disclosure, or comprising a combined slide rail assembly for a means of transport according to this disclosure, or comprising an interior trim assembly for a means of transport according to this disclosure.

[0051] The technical features mentioned above, those to be mentioned below, and those shown individually in the accompanying drawings can be combined arbitrarily, provided that the combined technical features are not contradictory. All feasible combinations of features are the technical content explicitly described herein. Any one of the multiple sub-features contained in the same statement can be applied independently, without necessarily being applied together with other sub-features. Attached Figure Description

[0064] Firstly, by using Figures 1 to 4 A first embodiment of the slide rail device 100 according to the present disclosure is described.

[0065] The slide rail device 100 disclosed herein can be used in a transport vehicle 200 (see...) Figure 11The vehicle 200 can be used in various applications, including transportation vehicles, such as passenger cars. The vehicle 200 can also be other land-based transportation vehicles, air-based transportation vehicles, or water-based transportation vehicles. For passenger cars, the vehicle 200 disclosed herein is particularly suitable for mid-to-large-sized SUVs or MPVs. Of course, the slide rail device 100 of this disclosure can also be used in other applications requiring slide rails, in addition to its use in transportation vehicles 200.

[0066] In such Figures 1 to 4 The slide rail device shown includes multiple, such as three, integrally formed lower slide rails 1. The lower slide rail 1 can be constructed as a groove. Of course, other forms of lower slide rails are also conceivable.

[0067] Multiple rows of upper slide rail components are installed within each lower slide rail 1. Each row of upper slide rail components forms an upper slide rail assembly 2, and these upper slide rail assemblies 2 are arranged sequentially along the moving direction of the upper slide rail components, or in other words, along the axial direction of the lower slide rail 1. Multiple upper slide rail components in each upper slide rail assembly 2 are respectively disposed within multiple parallel lower slide rails 1. Figures 1 to 4 The slide rail device shown can also be called a multi-row common rail scheme.

[0068] For each upper slide rail assembly 2, it can be as follows: Figure 1 and Figure 2As clearly seen, a single motor is provided as the driver 5, which can drive the corresponding upper slide rail assembly 2 to move. For each upper slide rail assembly 2, a single lead screw is provided as a travel member 4, which forms a travel section 3 for the upper slide rail assembly 2. Besides the lead screw, a rack can also be considered as the travel member 4, with a gear directly or indirectly connected to the driver 5 engaging with the rack. In this embodiment, one travel member 4 forms one travel section 3. The lead screw, as the travel member 4, is fixedly installed in the groove of the corresponding lower slide rail 1, and transmission is achieved through engagement with the lead screw nut in the gearbox, so as to cover the travel stroke of the upper slide rail assembly 2 equipped with the motor via the travel section 3. Therefore, in the first embodiment, a slide rail device 100 is provided, comprising three lower slide rails 1 and three upper slide rail assemblies 2 movable at the lower slide rails 1. Each upper slide rail assembly 2 is provided with a travel portion 3 for its own use and coupled to the corresponding upper slide rail assembly 2. Each travel portion 3 is configured to limit the travel distance of the coupled upper slide rail assembly 2. The travel portions 3 are constructed and arranged such that there is an overlap between the travel distances defined by any two adjacent travel portions 3 for different upper slide rail assemblies 2. Each lower slide rail 1 is provided with only one lead screw as a travel member 4, and this one travel member 4 forms one travel portion 3. Of course, in addition to this embodiment where only one lead screw is provided for each upper slide rail assembly 2, it is also conceivable to provide multiple lead screws for each upper slide rail assembly 2, with the corresponding travel portions 3 of these lead screws jointly defining a travel distance. Thus, multiple lead screws can be provided for one travel portion 3 according to actual needs for heavy-load conditions. This embodiment will be described in detail below.

[0069] Each upper slide rail assembly 2 includes a first upper slide rail component 21 and a second upper slide rail component 22, which are respectively disposed at the two outermost lower slide rails 1 of the three lower slide rails 1. Alternatively, the first upper slide rail component 21 and the second upper slide rail component 22 can be disposed at two directly adjacent lower slide rails 1. The primary purpose of providing at least the first upper slide rail component 21 and the second upper slide rail component 22 is to ensure the stable movement of the interior trim pieces mounted upon them.

[0070] For ease of description, the three upper slide rail assemblies 2 are referred to as the front row upper slide rail assembly 2a, the middle row upper slide rail assembly 2b, and the rear row upper slide rail assembly 2c from front to back; and the three lower slide rails 1 are referred to as the first lower slide rail 1a, the second lower slide rail 1b, and the third lower slide rail 1c from front to back.

[0071] For example Figure 1 and Figure 2Regarding the front upper slide rail assembly 2a and the rear upper slide rail assembly 2c shown, a motor as a driver 5 is mounted on one upper slide rail component, which is disposed in a lower slide rail 1 having a stroke portion 3 that matches the corresponding upper slide rail assembly 2. The other upper slide rail component is a driven rail, and its corresponding lower slide rail 1 does not have a stroke portion 3. This configuration can be referred to as a first upper slide rail assembly-stroke portion configuration. Figure 1 and Figure 2 In the embodiment shown, the first upper slide rail component 21 and the second upper slide rail component 22 are respectively disposed on the outermost side of the two lower slide rails 1 in order to achieve more stable movement of the interior trim parts placed on the two upper slide rail components. However, it is also conceivable that one of the upper slide rail components is not disposed on the outermost lower slide rail 1, but is disposed on the middle lower slide rail 1.

[0072] For the middle row upper slide rail assembly 2b, the stroke portion 3, which is matched with the corresponding upper slide rail assembly 2, is located between the first upper slide rail component 21 and the second upper slide rail component 22. This configuration can be referred to as the second upper slide rail assembly-stroke portion configuration. In the first embodiment, under the second upper slide rail assembly-stroke portion configuration, the first upper slide rail component 21 and the second upper slide rail component 22 of the middle row upper slide rail assembly 2b are located at the outer first lower slide rail 1a and the third lower slide rail 1c, while the corresponding stroke portion 3 is located in the middle second lower slide rail 1b. The motor corresponding to the stroke portion 3 is located on the third upper slide rail component 23, which can move on the middle second lower slide rail 1b. The upper slide rail components of the middle row upper slide rail assembly 2b are connected to each other by a bracket 6, such as a bracket plate, to achieve synchronized movement. In another embodiment, the upper slide rail components can also be connected together to the interior trim, such as the seat 201 or the leg rest 202 (see...). Figure 11 The movement of each upper slide rail component in the same upper slide rail assembly 2 is synchronized by using the skeleton of the upper slide rail assembly 2.

[0073] Specifically, in the front row upper slide rail assembly 2a, each upper slide rail component is arranged horizontally side-by-side in the first lower slide rail 1a and the third lower slide rail 1c. The motor is directly mounted on the first upper slide rail component 21 within the first lower slide rail 1a, and the lead screw forming the corresponding stroke portion 3 is mounted within the first lower slide rail 1a. The two upper slide rail components are connected together to the interior trim, such as the frame of the seat 201. In the middle row upper slide rail assembly 2b, each upper slide rail component is arranged horizontally side-by-side in the first lower slide rail 1a, the second lower slide rail 1b, and the third lower slide rail 1c. The motor is mounted on the third upper slide rail component 23 within the second lower slide rail 1b, and the lead screw forming the corresponding stroke portion 3 is mounted within the second lower slide rail 1b. A bracket 6 is horizontally mounted at the first, second, and third upper slide rail components 21, 22, and 23 to connect each upper slide rail component. The upper slide rail components of the rear row upper slide rail assembly 2c are arranged laterally side-by-side in the first lower slide rail 1a and the third lower slide rail 1c. The motor is directly mounted on the second upper slide rail component 22 within the third lower slide rail 1c, and the lead screw forming the corresponding stroke section 3 is mounted within the third lower slide rail 1c. The two upper slide rail components are connected together to the interior trim, such as the frame of the seat 201. For these three rows of upper slide rail assemblies 2, the front row upper slide rail assembly 2a and the rear row upper slide rail assembly 2c adopt the first upper slide rail assembly-stroke section configuration; while the middle row upper slide rail assembly 2b adopts the second upper slide rail assembly-stroke section configuration. Figure 1 and Figure 2In the illustrated embodiment, the middle row upper slide rail assembly 2b adopts a second upper slide rail assembly-stroke section configuration because the stroke section 3, which is matched with the corresponding upper slide rail assembly 2, is located between the first upper slide rail component 21 and the second upper slide rail component 22. Furthermore, a third upper slide rail component 23 is provided to facilitate motor placement. Alternatively, the middle row upper slide rail assembly 2b can also adopt a first upper slide rail assembly-stroke section configuration. In this case, one of the first upper slide rail component 21 and the second upper slide rail component 22 is located on the middle second lower slide rail 1b, while the other is located at either the first lower slide rail 1a or the third lower slide rail 1c, thus forming a first upper slide rail assembly-stroke section configuration, and eliminating the need for an additional third upper slide rail component 23. Furthermore, it is conceivable that the middle row upper slide rail assembly 2b does not have a third upper slide rail component 23 at the second lower slide rail 1b, but instead only has a motor and gearbox. The motor and gearbox are fixedly connected to the bracket 6, and the lead screw nut in the gearbox is connected to the lead screw drive in the second lower slide rail 1b. Therefore, for the second upper slide rail assembly - stroke section configuration, it is possible to place the third upper slide rail component 23 at the middle lower slide rail 1 with the lead screw and install the motor on the third upper slide rail component 23. In this case, in order to synchronize the movement of the three upper slide rail components in the same upper slide rail assembly 2, it is possible to set up the bracket 6 connecting the three upper slide rail components in the same upper slide rail assembly 2; otherwise, it is possible to eliminate the third upper slide rail component 23 and directly set the motor and gearbox on the bracket 6.

[0074] In the first embodiment, as described above, the three lower slide rails 1 are integrally formed. However, it should be noted that the integrally formed three lower slide rails 1 is a preferred embodiment. The purpose of integral forming is to obtain a particularly small opening width W of the lower slide rail assembly composed of the three lower slide rails 1. With a small opening width W, jamming or asynchronous movement can be avoided when two or three upper slide rail components are moved by a single motor. Therefore, it is also conceivable that the three lower slide rails 1 are spaced apart from each other. In some embodiments, the opening width W of the at least two lower slide rails 1 is at most five times, preferably four times, and more preferably three times the width of one lower slide rail 1. Here, the opening width W is as follows: Figure 4 The diagram shows the lateral spacing between the centers of the two outermost lower slide rails 1. Importantly, the lower slide rails 1 are arranged relative to each other in the lateral direction such that a single motor can move all the upper slide rail components in the corresponding upper slide rail assembly 2 without causing the corresponding upper slide rail assembly 2 to jam at the lower slide rail 1 or experience asynchronous movement. Here, "lateral direction" for each lower slide rail 1 refers to the direction oriented laterally to the axial direction of the lower slide rail 1.

[0075] In the first embodiment, any two adjacent sliding rails 1 are directly adjacent to each other, and share a common groove wall 9 between the two sliding rails 1 (e.g., Figure 3 (As shown). In addition, the lower rail assembly is manufactured by integral extrusion molding.

[0076] Besides integral molding, it is also conceivable that the three sliding rails 1 can be molded separately and, when spliced ​​together, form a sliding rail assembly through additional fixing means. In this disclosure, such fixing means can be form-locking and / or material-locking and / or force-locking. The forms of form-locking, material-locking, and force-locking are described above.

[0077] In the first embodiment, all three upper slide rail assemblies 2 are electrically moved back and forth by a motor and a corresponding lead screw. Therefore, the corresponding stroke portions 3 are all formed by the lead screw as the stroke element 4. Besides the lead screw, for electric adjustment, it is also conceivable to design the stroke element 4 as a rack, with the motor directly or indirectly connected to the gear, which can cooperate with the rack to drive the upper slide rail assembly 2 to move relative to the corresponding lower slide rail 1. Of course, other transmission mechanisms capable of linear movement are also conceivable. In addition to the above-mentioned electric adjustment, manual adjustment is also conceivable. When one or more of the upper slide rail assemblies 2 are made manually adjustable, a manually adjustable mechanism, such as a rack-and-pinion mechanism, and other possible mechanisms capable of manual back-and-forth adjustment and locking, can be directly employed. Furthermore, it is also conceivable to eliminate the lead screw and determine the corresponding stroke portion 3 by using two stops on the corresponding lower slide rail 1 that only function for the manually adjustable upper slide rail assembly 2 in conjunction with the lower slide rail 1.

[0078] exist Figure 4 The overlapping relationship between the stroke sections 3 in the first embodiment can be seen more clearly in the image. Here, the travel strokes defined by the corresponding stroke sections 3 for the first sliding rail 1a, the second sliding rail 1b, and the third sliding rail 1c are referred to as the first travel stroke, the second travel stroke, and the third travel stroke, respectively. Figure 4 It can be seen that there is overlap between the first and second travel distances, and also between the second and third travel distances. Furthermore, from... Figure 4 As can be clearly seen, each travel member 4 has a stop 7 on both sides, especially at both ends, and in particular a solid stop 7a. In this disclosure, the solid stop 7a can be used to achieve the overlap of the travel stroke defined by the travel part 3, thereby achieving a more robust travel stroke overlap structure with "intrinsic safety".

[0079] In addition to the arrangement structure in the first embodiment, other arrangement structures of the travel section 3 with respect to the lower slide rail 1 can also be conceived.

[0080] exist Figure 5 In the second embodiment shown, two lead screws can be arranged separately in the first lower slide rail 1a, while one lead screw can be arranged in the middle of the second lower slide rail 1b. The lead screw in the second lower slide rail 1b can overlap with the two lead screws in the first lower slide rail 1a in the lateral direction at its front and rear parts, respectively. Thus, overlap can also exist between the travel strokes defined by each pair of adjacent travel sections 3. That is, in this disclosure, the two travel sections 3 in any two adjacent upper slide rail assemblies 2 are located in different lower slide rails 1. Other aspects can be referred to in the first embodiment.

[0081] In both the first and second embodiments, there is at least one travel member 4 that forms only one travel portion 3. With this design, instead of having a single travel member 4 bear the load of, for example, two interior trim pieces, such as seat 201, simultaneously as in the prior art, it only needs to bear the load of one interior trim piece. As a result, the travel member 4 does not need to be designed for high loads, and can be designed to be thinner, thereby saving materials or simplifying the manufacturing process.

[0082] In addition, Figure 6 In the third embodiment shown, a long lead screw as a travel member 4 can be provided at the front of the first lower slide rail 1a, while a short lead screw as a travel member 4 can be provided at the rear of the second lower slide rail 1b. This short lead screw overlaps with the long lead screw in the lateral direction at the front. For a three-row arrangement, the travel member 4 of the long lead screw in the first lower slide rail 1a can be divided into two travel portions 3, for example, by a virtual stop point 7b (as shown by the dashed line). Therefore, for this long lead screw, the travel distance defined by its two travel portions 3 does not overlap with each other. However, there is an overlap between the travel distance defined by the travel portion 3 at the rear of the long lead screw in the first lower slide rail 1a and the travel distance defined by the travel portion 3 of the short lead screw in the second lower slide rail 1b. Other aspects can be referred to in the description of the first embodiment.

[0083] Figure 7 A fourth embodiment of the slide rail device 100 according to this disclosure is shown. The fourth embodiment differs from the first embodiment in that the front upper slide rail assembly 2a can be manually slid along the third lower slide rail 1c and can be stopped at two physical stops 7a, one of which ( Figure 7 The stop point 7 in the middle right part can be set on the inner wall of the third lower slide rail 1c. With the help of a locking structure (not shown), the front upper slide rail assembly 2a can be locked at the third lower slide rail 1c after reaching the target position. For other aspects, please refer to the description of the first embodiment.

[0084] exist Figure 8The diagram illustrates a fifth embodiment of the slide rail device 100 according to this disclosure. The fourth embodiment differs from the first embodiment in that two lead screws are provided as travel members 4 for the rear upper slide rail assembly 2c. These two lead screws each form a travel portion 3, and the respective travel portions 3 of the two lead screws together define a travel distance. This fifth embodiment can be targeted at heavy-load situations. Such a dual-lead screw design for heavy loads may be necessary when interior trim components on the rear upper slide rail assembly 2c, such as zero-gravity seats, integrate numerous functions and are relatively heavy. Other aspects can be referred to in the description of the first embodiment.

[0085] Next, using Figure 9 and Figure 10 The arrangement structure of the slide rail 1 according to the sixth and seventh embodiments of the slide rail device 100 according to this disclosure is shown. Figure 9 In this configuration, the three sliding guide rails 1 are all arranged spaced apart from each other or adjacent to each other. The opening width W of these sliding guide rails 1 is three times the width of a single sliding guide rail 1. Figure 10 In the three lower slide rails 1, two lower slide rails 1 are arranged close to each other, while two lower slide rails 1 are arranged adjacent to each other. Figure 9 and Figure 10 Both arrangement structures allow a single driver 5 to move all upper slide rail components in the corresponding upper slide rail assembly 2 without causing the upper slide rail assembly 2 to jam at the lower slide rail 1 or resulting in asynchronous movement. Besides Figure 9 and Figure 10 Besides the sliding track 1 arrangement shown, other feasible sliding track 1 arrangements can also be conceived.

[0086] The slide rail device 100 disclosed herein can be arranged not only along the longitudinal direction of the transport vehicle 200 as is usually the case, but also along the transverse direction of the transport vehicle 200. Interior components, such as a seat 201, leg rest 202, or footrest, can be installed on the slide rail device 100. The seat 201 may be, for example, a zero-gravity seat.

[0087] This section describes an interior component assembly for a passenger vehicle, using a passenger car as an example. This interior component assembly can be as follows: Figure 11The illustration includes two longitudinally extending slide rails 100 and interior trim arranged on the slide rails 100. For example, this passenger vehicle is a large four-seater, where the front interior trim may be a driver's seat 201 and a front passenger seat 201, the middle interior trim may be two leg rests 202, and the rear interior trim may be two seats 201, particularly zero-gravity seats. Here, there is an overlap between the travel distance defined by the travel portion 3 of the upper slide rail assembly 2 for the front seat 201 and the travel distance defined by the travel portion 3 of the upper slide rail assembly 2 for the middle row leg rest 202, and there is an overlap between the travel distance defined by the travel portion 3 of the upper slide rail assembly 2 for the middle row leg rest 202 and the travel distance defined by the travel portion 3 of the upper slide rail assembly 2 for the rear seat 201, especially the zero-gravity seat; thus, a very flexible relative positional relationship can be achieved between the front seat 201, the middle row leg rest 202 and the rear seat 201, especially the zero-gravity seat, so that a wide variety of usage scenarios can be realized without being limited by the travel portion 3 when designing scenarios, thereby providing passengers with extremely high emotional value.

[0088] also, Figure 12 As shown, the slide rail devices 100 can also be combined to form a modular slide rail assembly. Again, taking a passenger car as an example, another interior trim assembly for a passenger car is described, which can be as follows... Figure 12 The diagram shows a combined slide rail assembly comprising two first slide rail devices 100a extending longitudinally along the vehicle 200 and a second slide rail device 100b extending transversely along the vehicle 200. Furthermore, the interior trim assembly includes interior trim disposed on the second slide rail device 100b. Here, the interior trim may be a seat 201. Figure 12 In the illustrated embodiment, the passenger vehicle can be a six-seat passenger vehicle, wherein the first row seats 201 and the second row seats 201 can be designed to be position-adjustable, while the third row seats 201 can be position-fixed. The first slide rail device 100a can be a conventional slide rail device, while the second slide rail device 100b can be a slide rail device 100 according to the present disclosure. The second row seats 201 can be two zero-gravity seats, which can be arranged on such a second slide rail device 100b, thereby allowing them to move flexibly in the lateral direction along the lateral direction of the vehicle. If the passenger vehicle has rear-wheel steering, then as Figure 12As shown, there are raised structures on both sides of the third-row seat 201. The height of these raised structures is higher than the seat surface of the third-row seat 201. This means that even when the zero-gravity seat is adjusted to the center position (because the conventional lateral sliding rail device 100 sets the stop point at the center to evenly distribute the travel, so even in the center position, only one side of the zero-gravity seat is against the center line), the raised structures caused by the rear wheel steering function interfere with the backrest tilt angle of the zero-gravity seat when it is tilted backward. When the second sliding rail device 100b is the sliding rail device 100 according to this disclosure, the lateral travel can be flexibly set, allowing at least one zero-gravity seat to be adjusted laterally to a position unaffected by the raised structures, thereby achieving a more flat, tilted-back position for the zero-gravity seat. Of course, in other embodiments, depending on the actual application requirements, it is also conceivable that the first slide rail device 100a is the slide rail device 100 according to the present disclosure, while the second slide rail device 100b is a conventional slide rail device; or the first slide rail device 100a and the second slide rail device 100b are both slide rail devices 100 according to the present disclosure.

[0089] In addition to the above, when the sliding rail device 100 is arranged laterally according to this disclosure, better boarding and alighting can be achieved. For example, for passengers who want to sit in the third row, more access space can be provided for passengers who want to sit in the third row on the side where they want to board by allowing the second-row seats 201 to make way for them with a greater travel distance, thereby improving passenger satisfaction.

[0090] As can be clearly seen from the above description, the slide rail device 100 according to this disclosure allows for a very flexible arrangement of the travel section 3 within the slide rail device 100. Furthermore, by employing the slide rail device 100 according to this disclosure, a wide variety of application scenarios can be realized within the interior space of the transport vehicle 200, providing designers with extremely high flexibility in scenario design.

[0091] As can be clearly seen from the above description, the slide rail device according to this disclosure allows for a very flexible travel setting within the slide rail device itself. Furthermore, by employing the slide rail device according to this disclosure, a wide variety of application scenarios can be realized within the interior space of a transport vehicle, providing designers with extremely high flexibility in scenario design.
