Description

Seat adjustment device, seat structure and movable device Technical Field

[0001] The present application relates to the technical field of mechanical design, and provides a seat adjustment device, a seat structure, and a movable device. Background Art

[0002] With the rapid development of automobiles, users' demands for comfort are becoming increasingly demanding. To meet these demands, some cars have added movable seats, which adjust the seat's rotation angle and sliding position to meet the comfort requirements of different users. However, current seat designs, especially those in the rear seats, still have shortcomings. For example, when the rear seats are slid to their full front position, an inactive area is created between the rear seats and the trunk trim, encroaching on the trunk's storage space and hindering the user experience.

[0003] Therefore, the design scheme for seat movement needs further research.

[0004] Summary of the Invention

[0005] The present application provides a seat adjustment device, a seat structure and a movable device, which are used to reduce the impact of seat sliding on the storage space of a luggage compartment and improve the user experience.

[0006] In the first aspect, the present application provides a seat adjustment device, including a bracket structure, a first cover plate and a second cover plate, the first end of the bracket structure is fixedly connected to the seat pan frame of the seat, the second end of the bracket structure is respectively connected to the first end of the first cover plate and the first end of the second cover plate, for realizing relative rotation between the first cover plate and the second cover plate, the second end of the first cover plate is crimped onto the trunk trim, and the second end of the second cover plate is crimped onto the seat backrest.

[0007] It should be pointed out that when one component is crimped onto another component, it means that the component is overlapped on the other component through pressure, and its overlapping end point may only contact the other component but not be fixed to the other component, or it may be directly fixed to the other component, without specific limitation.

[0008] With this seat adjustment device, when the seat pan frame drives the seat to slide forward and backward, it also drives the second cover plate forward and backward via the bracket structure. This minimizes the creation of new inactive areas due to the forward and backward sliding of the seat, reduces the amount of storage space encroaching on the trunk, and improves the user experience. Furthermore, with this seat adjustment device, regardless of the seatback's rotation position, the gap between the trunk trim and the seatback is blocked by the first cover plate, the second cover plate, and the bracket structure. This not only prevents foreign objects from falling, but also creates an aesthetically pleasing appearance and is load-bearing, effectively improving the aesthetics and neatness of the cabin.

[0009] In one possible design, the support structure may include an extension support and an elastic hinge, wherein the first end of the extension support is the first end of the support structure, and the elastic hinge is fixedly arranged at the second end of the extension support and respectively connects the first end of the first cover plate and the first end of the second cover plate. The elastic hinge refers to a hinge equipped with an elastic mechanism, which may be a spring, a coil spring or other similar structure. Specifically, the elastic hinge includes a rotating shaft and two blades arranged around the rotating shaft, the first end of the first cover plate can be fixed to one of the blades, and the second end of the first cover plate can be fixed to the other blade, so that the relative rotation of the first cover plate and the second cover plate can be achieved through the rotation of the first blade or the second blade around the rotating shaft.

[0010] In the above design, the elastic hinge is a relatively common rotating connection part. By using the elastic hinge to achieve relative rotation between the first cover plate and the second cover plate, the production cost of the seat adjustment device can be reduced and the structure and installation method of the seat adjustment device can be simplified.

[0011] In a possible design, the support structure may further include an extended crossbeam, which is fixedly disposed at the second end of the extended support and is used to install an elastic hinge to perform a fixing and supporting function.

[0012] In one possible design, the first cover plate and the second cover plate are integrally formed to further enhance the aesthetics of the seat structure.

[0013] In a further design, the first end of the first cover plate and the first end of the second cover plate can be connected by a soft material. The soft material can be a carpet, elastic cloth, rubber, thread, silicone, thermoplastic polyurethane (TPU), thermoplastic elastomer (TPE), thermoplastic rubber (TPR), or other elastic material. When the seat back is folded down, the soft material is in a minimally compressed state. As the seat slides forward and backward or the seat back rotates, the soft material is compressed or relaxed accordingly, allowing the second cover plate to rotate around the first cover plate under the pressure of the soft material, adaptively adjusting the position of the press-fit with the seat back.

[0014] In one possible design, the second cover plate may include an elastic material, and the second end of the second cover plate is fixed to the backrest of the seat. The elastic material may be stretch fabric, spring steel, rubber, sponge or latex, or a cross-linked reaction product of a mixture of at least one of uncured stretch fabric, spring steel, rubber, sponge or latex and a polymer hydrogel, or other elastic material. Elastic materials are lighter than rigid materials. Therefore, by using an elastic material to make the second cover plate and fixing the second end of the second cover plate to the seat back, not only can the elastic material's expansion and contraction deformation be relied upon to shield the grooves and gaps generated during the rotation of the seat back and reduce the ineffective area generated during the forward and backward sliding of the seat, but the weight of the seat adjustment device can also be reduced, thereby contributing to a lightweight design of the movable device.

[0015] In one possible design, a slot is formed on the trunk trim corresponding to the position of the first cover plate. The first cover plate fits into the slot to achieve a press-fit connection with the trunk trim. This allows the first cover plate to slide along the slot as the seat slides forward or backward or the seatback rotates, adaptively adjusting its press-fit position with the trunk trim.

[0016] In a further design, the second end of the first cover plate may comprise an elastic material, and the second end of the first cover plate may be fixed to the end of the slot opposite the first cover plate. This allows the elastic material at the second end to completely cover the entire slot even if the first end of the first cover plate slides back and forth, ensuring a seamless contact between the first cover plate and the trunk trim, effectively preventing foreign objects from falling into the slot.

[0017] In a further design, the second end of the first cover plate can be realized by an elastic mechanism such as a spring or a coil spring, or an elastic mechanism such as a spring or a coil spring can be set inside it and wrapped with a soft shell such as elastic cloth on the outside to make its appearance more beautiful.

[0018] In a further design, the upper surface of the trunk trim is flush with the upper surface of the first cover. This not only improves the aesthetics of the cabin, but also avoids the formation of bosses or depressions between the first cover and the trunk trim when the seat moves forward and backward or the seat back rotates, making it easier to place luggage and improving its practicality.

[0019] It should be noted that the above designs can be combined with each other to obtain new implementation solutions, and there is no specific limitation.

[0020] In a second aspect, the present application provides a seat structure comprising a seat, a seat pan frame, a trunk trim, and a seat adjustment device as described in any one of the designs in the first aspect above, wherein the seat pan frame is arranged below the seat to drive the seat to slide, and the trunk trim is arranged behind the seat to place luggage.

[0021] In a third aspect, the present application provides a movable device comprising the seat structure as described in the second aspect above.

[0022] For the beneficial effects of the second to third aspects mentioned above, please refer to the technical effects that can be achieved by the corresponding design in the first aspect mentioned above, and no further details will be given here. BRIEF DESCRIPTION OF THE DRAWINGS

[0042] In order to make the purpose, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings.

[0043] It should be noted that the embodiments illustrated below can be implemented in various forms and should not be construed as being limited to the embodiments described below; on the contrary, providing these embodiments can make the embodiments of the present application more comprehensive and complete, and can fully convey its concept to those skilled in the art. Moreover, the specific details described in the following description are intended to facilitate a full understanding of the embodiments of the present application by those skilled in the art, but it should be understood that the embodiments of the present application can be implemented in a variety of other ways different from those described herein, and those skilled in the art can make similar generalizations without violating the connotation of the present application, that is, the embodiments of the present application are not limited by the specific embodiments disclosed below. Similarly, the subsequent descriptions in the specification are all preferred embodiments for implementing the embodiments of the present application. Of course, the description is for the purpose of illustrating the general principles of the embodiments of the present application, and is not intended to limit the scope of the embodiments of the present application. The scope of protection of the embodiments of the present application shall be determined by the appended claims.

[0044] In addition, the drawings of the embodiments of the present application are only used to illustrate relative positional relationships and do not represent true proportions. The words expressing positions and directions described in the embodiments of the present application are all explained using the drawings as examples, but can be changed as needed, and the changes made are included in the scope of protection of the embodiments of the present application. The same symbols in the drawings represent the same or similar structures, and their repeated descriptions will be omitted.

[0045] Please refer to Figure 1, which is a structural diagram of a movable device provided in an embodiment of the present application. Among them, the movable device 1 can be an intelligent transportation equipment such as a car, a ship, a drone, a train, a van, a truck, an airplane, a yacht, or other forms of equipment with the function of carrying people and goods, and the embodiment of the present application does not limit this. The movable device 1 of the embodiment shown in Figure 1 is explained by taking a car as an example. The cabin of the car is provided with a plurality of seats for passengers to sit, including front seats and rear seats. The front seats are also called the first row of seats, and the rear seats include the second row of seats. In some scenarios, the third row of seats or more rear seats are also included. In addition, in order to realize the carrying function, a luggage compartment space is usually provided behind the rear seats, and the luggage compartment space is paved with luggage compartment panels for placing luggage.

[0046] With the development of connected vehicle technology, the role of cabin comfort in enhancing vehicle competitiveness is becoming increasingly prominent. To accommodate user needs, most rear seats in vehicles can be folded down or flat, allowing for greater luggage space when transporting large items. However, because the rear seat backrests can rotate, a gap can easily form between the seat backrest and the luggage compartment trim. For example, see Figure 2, which shows a schematic diagram of a seat structure in different rotational states. The seat includes a seat backrest, a seat cushion, and a seat shaft. The seat shaft flexibly connects the seat backrest and seat cushion. The seat backrest rotates along the seat cushion as the seat shaft rotates, and a luggage compartment trim is provided on the rear side of the seat backrest. However, whether the seat back is in the unfolded state as shown in Figure 2 (A), the bent state as shown in Figure 2 (B), or the folded state as shown in Figure 2 (C), there is a groove or gap between the seat back and the trunk trim. Obviously, this seat structure is not only unsightly, but also prone to foreign objects falling, which is not conducive to the neat design of the cabin.

[0047] To address the aforementioned issues, the industry has provided a new seat structure, as shown in Figure 3. This new seat structure utilizes a rotating baffle structure to block the gap between the seat back and the trunk trim. Specifically, the baffle structure includes a baffle 310 and a spring-loaded baffle shaft 320. One end of the baffle 310 is fixed to the baffle shaft 320, and the other end rests on the seat back. When the seat back rotates from the deployed position (as shown in Figure 3 (A) ), to the bent position (as shown in Figure 3 (B) ), and then to the folded position (as shown in Figure 3 (C) ), the baffle 310 rotates with the seat back under the elastic force of the baffle shaft 320 , adaptively resting on the seat back and blocking the gap between the seat back and the trunk trim.

[0048] While the aforementioned baffle structure can provide a shielding effect during seatback rotation, it's only applicable to seats with only a rotating backrest. If the seat has both a rotating backrest and a fore-and-aft sliding function, the baffle length within the baffle structure needs to be adjusted accordingly. For example, please refer to Figure 4, which shows a schematic diagram of a new, adjusted seat structure in different sliding positions. Compared to a seat structure with only a rotating backrest, the fore-and-aft sliding seat structure incorporates a seat basin frame. The seat cushion is secured to the basin frame and can move with it toward or away from the trunk trim. Considering that the trunk trim is typically located behind the seatback, for ease of understanding, the direction away from the trunk trim is referred to as the front, and the direction toward the trunk trim is referred to as the rear. Based on this, referring to Figures 3 and 4, in order to adapt to the forward sliding stroke of the seat, the length of the baffle 310 in the adjusted new seat structure also needs to be increased accordingly. This will not only make the cabin shape unsightly, but also, when the seat slides from the rearmost position as shown in Figure 4 (A) to the middle position as shown in Figure 4 (B), and then to the frontmost position as shown in Figure 4 (C), the overlap angle between the baffle 310 and the seat back gradually increases, causing the triangular invalid area formed between the baffle 310, the seat back and the seat cushion to gradually increase. This triangular invalid area encroaches on the storage space of the luggage compartment, which is an industry pain point in the current seat structure design. Therefore, how to eliminate this triangular invalid area is crucial to increasing the storage space of the luggage compartment and thus improving the user experience.

[0049] In view of this, an embodiment of the present application provides a seat adjustment device, which can eliminate the triangular invalid area between the baffle, seat back and seat cushion as much as possible during the process of the seat sliding back and forth, reduce the storage space occupied by the trunk trim, and improve the user experience. Furthermore, it can also block the gap between the trunk trim and the seat back during the rotation of the backrest, prevent foreign objects from falling, and improve the aesthetics and cleanliness of the cabin.

[0050] The specific implementation of the seat adjustment device provided in the embodiment of the present application is described below through specific embodiments.

[0051] FIG5 exemplarily illustrates a structural diagram of a seat adjustment device provided in an embodiment of the present application. The seat adjustment device 500 can be integrated into a seat or exist independently of the seat. In this example, the seat adjustment device 500 includes a support structure 510, a first cover plate 521, and a second cover plate 522. The first end (a1) of the support structure 510 is fixedly connected to the seat pan frame of the seat. The second end (a2) of the support structure 510 is respectively connected to the first end (b1) of the first cover plate 521 and the first end (c1) of the second cover plate 522, for enabling relative rotation between the first cover plate 521 and the second cover plate 522. The second end (b2) of the first cover plate 521 is crimped onto the trunk trim, and the second end (c2) of the second cover plate 522 is crimped onto the seat back.

[0052] As previously mentioned, "a component being pressed against another component" means that the component rests on the other component through pressure. The overlapping end point may simply contact the other component but not be fixed to the other component, or it may be directly fixed to the other component. For example, in the seat adjustment device shown in Figure 5, the first cover plate 521 rests on the trunk trim due to gravity. The second end b2 of the first cover plate 521 may simply contact the trunk trim or be directly fixed to the trunk trim. Correspondingly, the second cover plate 522 rests on the seat back due to the reaction force provided by its relative rotation with the first cover plate 521. The second end c2 of the second cover plate 522 may simply contact the seat back or be directly fixed to the seat back, without limitation. Furthermore, the term "pressed connection" used herein is merely one way of describing this connection relationship, and other expressions are also possible. For example, in some embodiments, this connection relationship is also referred to as "overlap connection." However, it should be understood that both "overlap connection" and "pressed connection" represent the same meaning and do not represent an essential difference between the two.

[0053] In some embodiments, the first end a1 of the bracket structure 510 can be connected to the seat basin frame of the seat by any fixed connection method, for example, it can be a mechanical connection method, such as riveting, bolt connection, threaded connection, key connection, pin connection, snap connection, lock connection or plug-in connection, etc., or it can be a welding method, such as arc welding, submerged arc welding, gas shielded welding, spot welding, laser welding or other welding methods using electric energy, or gas welding, atomic hydrogen energy welding and cast welding or other welding methods using chemical energy, or forging welding, cold pressure welding, explosion welding, friction welding or other welding methods using mechanical energy, or it can be a bonding method, such as adhesive bonding or solvent bonding, etc.

[0054] In some embodiments, the second end a2 of the support structure 510 may be provided with a rotating connection member, which may be a hinge, a rotating shaft, a bearing, a hinge, or other components or assemblies that can allow relative rotational movement between two objects. The rotating connection member respectively connects the first cover plate 521 and the second cover plate 522 to realize the rotation of the second cover plate 522 relative to the first cover plate 521.

[0055] In other embodiments, the first cover plate 521 and the second cover plate 522 can be connected by an elastic component. This elastic component is fixedly connected to the support structure 510 and can be an elastic portion of the first cover plate 521 or the second cover plate 522, or a separate elastic cover plate, which is used to combine the first cover plate 521 and the second cover plate 522 into a single cover plate. In this way, under the support of the support structure 510, the second cover plate 522 can rotate relative to the first cover plate 521 due to the elastic force of the elastic component.

[0056] In the seat adjustment device 500 shown in Figure 5, since the first end a1 of the bracket structure 510 is fixed to the seat basin frame, when the seat slides back and forth with the seat basin frame, the bracket structure 510 will also move back and forth accordingly, driving the second end a2 of the bracket structure to move back and forth accordingly, and then driving the second cover plate 522 to move back and forth as well. In this way, during the entire process of the seat sliding back and forth, the triangular invalid area formed by the second cover plate 522, the seat back and the bracket structure 510 may remain basically unchanged, which can avoid as much as possible the generation of new invalid areas due to the sliding of the seat back and forth, reduce the encroachment on the storage space of the luggage box, and effectively improve the user experience. In addition, since the first cover plate 521 is pressed onto the trunk trim, the second cover plate 522 is pressed onto the seat back, and the first cover plate 521 and the second cover plate 522 are connected by the bracket structure 510, no matter which position the seat back is rotated to, the gap between the trunk trim and the seat back can be blocked by the first cover plate 521, the second cover plate 522 and the bracket structure 510. This design not only prevents foreign objects from falling, but also has an elegant appearance and can bear weight, which helps to improve the beauty and neatness of the cabin.

[0057] It should be noted that in the seat adjustment device 500, the support structure 510, the first cover plate 521, or the second cover plate 522 can be made of rigid and / or flexible materials, as long as the second end a2 of the support structure 510 and the second cover plate 522 can move back and forth accordingly as the seat basin frame slides back and forth. To further clarify the embodiments of the present application, the following further describes several possible specific implementations of the support structure 510, the first cover plate 521, and the second cover plate 522 in the seat adjustment device 500, based on the seat adjustment device 500 shown in FIG. 5 .

[0058] Implementation Plan 1

[0059] Please refer to Figure 6, which is a schematic diagram of the specific structure of a seat adjustment device provided by an embodiment of the present application. The seat adjustment device 500 includes a support structure 510, a first cover plate 521, and a second cover plate 522. The support structure 510 includes an extension bracket 511 and an elastic hinge 512. The first end of the extension bracket 511, i.e., the first end a1 of the support structure 510, is fixed to the seat basin frame. The elastic hinge 512 is fixed to the second end (d2) of the extension bracket 512 and connects the first end b1 of the first cover plate 521 and the first end c1 of the second cover plate 522, respectively. The first cover plate 521 presses against the trunk trim, and its second end b2 contacts the trunk trim but is not fixed thereto. Correspondingly, the second end c2 of the second cover plate 522 presses against the seat back and contacts the seat back but is not fixed thereto.

[0060] Specifically, the elastic hinge 512 refers to a hinge equipped with an elastic mechanism, which can be a spring, a coil spring, or other similar structure. Please refer to Figure 7, which shows a structural schematic diagram of an elastic hinge provided in an embodiment of the present application. The elastic hinge 512 includes a first fan blade 5121, a second fan blade 5122, a hinge shaft 5123, and an elastic mechanism 5124. The first fan blade 5121 and the second fan blade 5122 are respectively wrapped around the hinge shaft 5123 and can rotate with the hinge shaft 5123. The elastic mechanism 5124 is wound around the hinge shaft 5123, and its two pop-up ends T1 and T2 are in contact with the first fan blade 5121 and the second fan blade 5122, respectively. In practice, the first end b1 of the first cover plate 521 can be mounted in at least one opening of the first blade 5121 by means of screws and nuts or other fitting methods, thereby achieving a fixed connection between the first cover plate 521 and the first blade 5121. Correspondingly, the first end c1 of the second cover plate 522 can be mounted in at least one opening of the second blade 5122 by means of screws and nuts or other fitting methods, thereby achieving a fixed connection between the second cover plate 522 and the second blade 5122. With this elastic hinge structure, during the rotation of the seat back or the forward and backward sliding of the seat, the second blade 5122 can rotate in the direction of rotation of the seat back under the elastic force of the elastic mechanism 5124, thereby driving the rotation of the second cover plate 522 fixed to the second blade 5122.

[0061] In some embodiments, please continue to refer to FIG6 , the support structure 510 may further include an extension beam 513, which is fixedly disposed at the second end d2 of the extension support 511, for mounting the elastic hinge 512 to perform a fixing and supporting function. It should be noted that the elastic hinge 512 and the extension beam 513 may be mounted in any manner that does not affect the rotation of the hinge shaft 5123, such as by opening a hole or a groove on the extension beam 513 and engaging the hinge shaft 5123 in the hole or groove, or by providing a bearing bracket on the hinge shaft 5123 and fixing the bearing bracket on the extension beam 513, etc. There are many possible installation methods, which are not listed here one by one.

[0062] Based on the seat adjustment device shown in Figure 6, Figure 8 exemplarily shows a structural schematic diagram of a seat structure provided by an embodiment of the present application in different states, wherein Figure 8 (A) shows the state when the seat is located at the rearmost position and the seat backrest has the largest unfolding angle, Figure 8 (B) shows the state when the seat slides forward to the middle position, Figure 8 (C) shows the state when the seat slides forward to the frontmost position, Figure 8 (D) shows the state when the seat backrest is rotated to the middle position, and Figure 8 (E) shows the state when the seat backrest is rotated to the lay down position.

[0063] Referring to Figures 6 and 8 (A) to 8 (C), since the first end a1 of the extension bracket 511 is fixed to the seat basin frame, when the seat basin frame drives the seat to slide forward, the extension bracket 511 fixed to the seat basin frame, the extension beam 513 fixed to the second end d2 of the extension bracket 511, and the elastic hinge 512 fixed to the extension beam 513 also move forward, driving the first cover plate 521 to slide in the direction away from the trunk trim, and the second cover plate 522 rotates relative to the first cover plate 521 under the elastic force of the elastic hinge 512, adaptively adjusting the contact position of its second end c2 with the seat back, and overlapping the seat back. On the contrary, when the seat basin frame drives the seat to slide backward, the extended bracket 511 fixed on the seat basin frame, the extended beam 513 fixed on the second end d2 of the extended bracket 511, and the elastic hinge 512 fixed on the extended beam 513 also slide backward, driving the first cover plate 521 to slide toward the direction close to the trunk trim, and the second cover plate 522 rotates relative to the first cover plate 521 under the elastic force of the elastic hinge, adaptively adjusting the contact position of its second end c2 with the seat back, and overlapping the seat back.

[0064] In some embodiments, in order to ensure that the first cover plate 521 can cover the grooves and gaps generated between the trunk trim and the seat back during the forward and backward sliding of the seat, the length of the first cover plate 521 needs to be configured to be greater than the total sliding stroke of the seat basin frame. For example, the length of the first cover plate 521 can be configured to be slightly greater than the sum of the total sliding stroke of the seat basin frame and the distance between the trunk trim and the elastic hinge 512 when the seat is in the rearmost position. In this way, not only can the grooves and gaps generated by the forward and backward sliding of the seat be effectively blocked, foreign objects can be prevented from falling while ensuring aesthetics, but also manufacturing materials can be saved to achieve the effect of weight reduction.

[0065] It should be noted that during the seat's fore-and-aft sliding motion, the travel of the first cover plate 521 on the trunk trim is approximately equal to the travel of the seat pan frame (possibly due to the friction between the first cover plate 521 and the trunk trim being slightly less than the travel of the seat pan frame). Consequently, the second cover plate 522 undergoes essentially no relative rotation relative to the first cover plate 521, and the triangular dead zone formed between the second cover plate 522, the support structure 510, and the seat back also remains essentially unchanged. As shown in Figures 8(A) to 8(C), this triangular dead zone is very small and negligible compared to the overall large trunk space. Thus, the seat adjustment device 500 illustrated in Figure 6 substantially eliminates the dead zone during the entire fore-and-aft sliding motion of the seat, minimizing wasted trunk space throughout the sliding process. This effectively maximizes trunk space utilization, resolves the industry issue of encroaching on trunk space, and significantly improves the user's storage experience.

[0066] With reference to Figures 6, 8(A), 8(D), and 8(E), the second cover plate 522 rotates relative to the first cover plate 521 via the elastic hinge 512. As the seat back rotates clockwise, the second cover plate 522, under the elastic force of the elastic hinge 512, rotates clockwise accordingly, adaptively adjusting the contact position of its second end c2 with the seat back, and overlapping the seat back. This overlapping arrangement effectively obscures the groove and gap between the seat back and the trunk trim during seat back angle adjustment. Specifically, when the seat back is rotated to the reclined position illustrated in Figure 8(E), the elastic hinge 512 is at its minimum compression, and the second cover plate 522, the elastic hinge 512, and the first cover plate 521 approximately form a flat surface, effectively obscuring the groove and gap between the reclined seat back and the trunk trim. Conversely, as the seat back rotates counterclockwise, the second cover plate 522 rotates counterclockwise due to the elastic force of the elastic hinge 512. When the seat back rotates to the expanded position shown in FIG8(A), the elastic hinge 512 is in its maximum compression state. The second cover plate 522, under the elastic force of the elastic hinge 512, provides maximum contact force against the seat back and adaptively adjusts the contact position of its second end c2 with the seat back, overlapping the seat back. Thus, the seat adjustment device 500 shown in FIG6 effectively blocks the groove and gap between the luggage compartment trim and the seat back throughout the entire seat back rotation process, ensuring both aesthetics and preventing foreign objects from falling.

[0067] It should be pointed out that the minimum compression state of the elastic hinge 512 can be considered as the most relaxed state of the elastic mechanism 5123 in the elastic hinge 512. Usually, the elastic mechanism 5123 can be configured to still have a certain compression in this state, so that a certain pressure can still be provided to the seat back when the seat back is folded down, thereby preventing the seat back from suddenly bouncing up.

[0068] In implementation plan one, the elastic hinge is a relatively common rotating connection part. By using the elastic hinge to achieve the relative rotation of the first cover plate and the second cover plate, it can not only rely on the elastic force of the elastic hinge to achieve the effect of covering the grooves and gaps generated during the rotation of the seat back and reducing the invalid triangular area generated during the forward and backward sliding of the seat, but also reduce the production cost of the seat adjustment device and simplify the structure and installation method of the seat adjustment device.

[0069] Implementation Plan 2

[0070] FIG9 is a schematic diagram illustrating the specific structure of another seat adjustment device according to an embodiment of the present application. The seat adjustment device 500 includes a support structure 510, a first cover plate 521, and a second cover plate 522. A first end a1 of the support structure 510 is fixed to the seat basin frame of the seat. A second end a2 of the support structure 510 is connected to a first end b1 of the first cover plate 521 and a first end c1 of the second cover plate 522, respectively. The second end b2 of the first cover plate 521 presses against the trunk trim, contacting the trunk trim but not fixed thereto. The second cover plate 522 comprises an elastic material, and a second end c2 of the second cover plate 522 is fixed to the seat back. The second cover plate 522 comprising an elastic material may mean that the second cover plate 533 is made of an elastic material, such as being made entirely of an elastic material, or being made of a mixture of an elastic and non-elastic material. The elastic material can be stretch fabric, spring steel, rubber, sponge or latex, etc., or a cross-linked reaction product of a mixture of at least one of uncured stretch fabric, spring steel, rubber, sponge or latex and a polymer hydrogel, or other elastic materials.

[0071] Please refer to Figure 10, which shows a structural schematic diagram of the seat structure in this embodiment provided in the embodiment of the present application when it is in different states, wherein Figure 10 (A) shows the state when the seat is located at the rearmost position and the seat backrest is at the maximum unfolding angle, Figure 10 (B) shows the state when the seat slides forward to the middle position, Figure 10 (C) shows the state when the seat slides forward to the frontmost position, Figure 10 (D) shows the state when the seat backrest is rotated to the middle position, and Figure 10 (E) shows the state when the seat backrest is rotated to the lay down position.

[0072] Referring to Figures 9 and 10 (A) through 10 (C), as the seat pan frame drives the seat to slide forward and backward, the support structure 510 fixed thereto also slides forward and backward, driving the first cover plate 521 connected to the support structure 510 to also slide forward and backward. Furthermore, because the second end c2 of the second cover plate 522 is fixed to the seat back, when friction causes the first cover plate 521 to slide forward and backward on the luggage compartment trim slightly less than the forward and backward sliding travel of the seat pan frame, the second cover plate 522 deforms under the action of its elastic material and adaptively clings to the seat back, minimizing the triangular ineffective area formed between the second cover plate 522, the support structure 510, and the seat back, reducing space waste in the luggage compartment during the entire sliding process, and effectively maximizing luggage compartment space utilization.

[0073] Referring to Figures 9, 10(A), 10(D), and 10(E), during clockwise or counterclockwise rotation of the seatback, the second cover plate 522 rotates with the seatback. Furthermore, because the second end c2 of the second cover plate 522 is fixed to the seatback, the elastic material of the second cover plate 522 deforms during rotation, adaptively clinging to the seatback. This elastic material's tensile or compressive deformation effectively blocks the groove and gap between the seatback and the trunk trim during angle adjustment. Specifically, when the seatback is rotated to the reclined position (illustrated in Figure 10(E)), the elastic material of the second cover plate 522 stretches to its maximum length. This stretched elastic material and the first cover plate 521 form a substantially flat surface, effectively blocking the groove and gap between the reclined seatback and the trunk trim.

[0074] It should be noted that in the second embodiment, the support structure 510 may include only one extension support for supporting the first cover plate 521 and the second cover plate 522. In this case, the seat adjustment device 500 can directly rely on the elastic deformation of the second cover plate 522 itself to adaptively stretch or shorten as the seat slides forward and backward or the seat back rotates to adapt to the seat back after the position change. Alternatively, the support structure 510 may also include an extension support and a movable connection member provided at one end of the extension support. The movable connection member may be, for example, the elastic hinge described in the first embodiment above. This can make the adaptive adjustment process of the second cover plate 522 smoother. Of course, the support structure 510 can also have other implementation methods, which will not be listed here one by one.

[0075] In the second implementation scheme, the elastic material is lighter than the rigid material. By using the elastic material to make the second cover plate and fixing the second end of the second cover plate on the seat back, it can not only rely on the expansion and contraction deformation of the elastic material to achieve the effect of covering the grooves and gaps generated during the rotation of the seat back and reducing the invalid triangular area generated during the forward and backward sliding of the seat, but also reduce the weight of the seat adjustment device, which helps to achieve a lightweight design of the movable device.

[0076] Implementation Plan 3

[0077] Please refer to Figure 11, which is a specific structural diagram of another seat adjustment device provided in an embodiment of the present application. The seat adjustment device 500 includes a bracket structure 510, a first cover plate 521 and a second cover plate 522. The first end a1 of the bracket structure 510 is fixed to the seat basin frame of the seat, and the second end a2 of the bracket structure 510 is connected to the first end b1 of the first cover plate 521 and the first end c1 of the second cover plate 522. A groove is opened on the trunk trim at a position corresponding to the first cover plate 521, and the first cover plate 521 is embedded in the groove to achieve crimping of its second end b2 with the trunk trim, and the second end c2 of the second cover plate 522 is crimped to the seat back. Among them, the width of the groove in the direction perpendicular to the paper shown in Figure 11 is slightly smaller than the width of the trunk trim in the direction perpendicular to the paper shown in Figure 11. It can be considered that the trunk trim is provided with a concave slide at a position relative to the first cover plate 521, and the first cover plate 521 is placed in the slide. When the seat slides forward and backward or the seat back rotates, the first cover plate 521 will slide in the slide accordingly.

[0078] In some embodiments, considering that when the first cover plate 521 slides forward in the slot, a groove may be formed between it and the trunk trim. This groove is prone to foreign objects falling into and difficult to clean. Therefore, to avoid the formation of a groove during the sliding process, FIG12 illustrates a schematic diagram of the specific structure of a first cover plate provided in an embodiment of the present application. In this example, the second end b2 of the first cover plate 521 may include an elastic material and be fixedly connected to the end of the slot opposite the first cover plate 521. In this way, even if the first end b1 of the first cover plate 521 slides back and forth, the elastic material at the second end b2 can completely cover the entire slot, ensuring that there is no gap at the contact point between the first cover plate 521 and the trunk trim, effectively preventing foreign objects from falling.

[0079] It should be noted that the second end b2 of the first cover plate 521 can be directly realized by an elastic mechanism such as a spring or a coil spring, or an elastic mechanism such as a spring or a coil spring can be set inside it and wrapped with a soft shell such as elastic cloth on the outside to make its appearance more beautiful.

[0080] In some embodiments, as shown in FIG11 , the upper surface of the first cover 521 is flush with the upper surface of the trunk trim, that is, there is no height difference between the first cover 521 and the trunk trim. This improves the cabin's aesthetics while also preventing the first cover 521 from creating a protrusion or depression between the first cover 521 and the trunk trim during seat forward and backward movement or seatback rotation, making it easier to place luggage and enhancing its practicality.

[0081] However, it should be understood that in other embodiments, the upper surface of the first cover plate 521 may be higher or lower than the upper surface of the luggage trim. Even if it is higher than the upper surface of the luggage trim, since a portion of the first cover plate 521 is sunken into the slot, the space occupied by the first cover plate 521 outside the luggage trim is reduced, thereby reducing the encroachment on the luggage compartment's storage space. Alternatively, even if it is lower than the upper surface of the luggage trim, since the first cover plate 521 is fully sunken into the slot, it not only does not encroach on the luggage compartment's storage space, but also provides an additional recess for small items of luggage, further expanding the luggage compartment's storage space.

[0082] Please refer to Figure 13, which shows a structural schematic diagram of the seat structure in this embodiment provided in the embodiment of the present application when it is in different states, wherein Figure 13 (A) shows the state when the seat is located at the rearmost position and the seat backrest is at the maximum expansion angle, Figure 13 (B) shows the state when the seat slides forward to the middle position, Figure 13 (C) shows the state when the seat slides forward to the frontmost position, Figure 13 (D) shows the state when the seat backrest is rotated to the middle position, and Figure 13 (E) shows the state when the seat backrest is rotated to the lay down position.

[0083] Referring to Figures 11 and 13(A) through 13(C), as the seat pan frame drives the seat forward and backward, the support structure 510 attached thereto also moves forward and backward, driving the second cover plate 522 and the first end b1 of the first cover plate 521 connected to the support structure 510 to move forward and backward. The forward and backward movement of the second cover plate 522 can reduce the amount of luggage storage space occupied. For details, please refer to the previous section and will not be repeated here. As the first end b1 of the first cover plate 521 moves forward and backward, the elastic material of the first cover plate 521, because its second end b2 is fixed to the luggage trim, changes its length under the action of external forces. As the seat slides backward, the elastic material in the first cover plate 521 experiences increased pressure from the slots in the luggage trim, shortening its length. As the seat slides forward, the pressure from the slots in the luggage trim decreases, extending its length. However, no matter sliding forward or backward, the first cover 521 covers the entire slot of the trunk trim from beginning to end and maintains the same plane as the trunk trim. The entire structure is beautiful and practical.

[0084] Referring to Figures 11, 13 (A), 13 (D) and 13 (E), when the seat back rotates clockwise or counterclockwise, the second cover plate 522 rotates with the rotation of the seat back and is adaptively pressed onto the seat back, while the first cover plate 521 covers the slot of the trunk trim in its entirety and remains in the same plane as the trunk trim.

[0085] In implementation plan three, a groove is cut on the trunk trim and the first cover is sunk into the groove to form a plane with the trunk trim. At the same time, an elastic connection is set between the first cover and one end of the trunk trim. This allows the first cover to always form the same plane with the trunk trim during the process of the seat sliding back and forth and the seat back rotating, ensuring that there is no gap at the contact position between the first cover and the trunk trim, preventing foreign objects from falling, and is both beautiful and practical.

[0086] Implementation Plan 4

[0087] Please refer to Figure 14, which is a specific structural diagram of another seat adjustment device provided in an embodiment of the present application. The seat adjustment device 500 includes a bracket structure 510 and an integrally formed cover plate 520. The integrally formed cover plate 520 includes a first cover plate 521, a soft cover plate 523 and a second cover plate 522. The first end b1 of the first cover plate 521 is connected to one end of the soft cover plate 523, and the other end of the soft cover plate 523 is connected to the first end c1 of the second cover plate 522. The second end b2 of the first cover plate 521 is crimped onto the trunk trim, and the second end c2 of the second cover plate 522 is crimped onto the seat back. The first end a1 of the bracket structure 510 is fixed to the seat basin frame of the seat, and the second end a2 of the bracket structure 510 is fixedly connected to the soft cover plate 523. The first cover plate 521 and the trunk trim panel can be pressed together in a manner that allows for contact but not fixed connection, as described in the first embodiment, or a fixed connection, as described in the third embodiment. The second cover plate 522 and the seat back can be pressed together in a manner that allows for contact but not fixed connection, as described in the first embodiment, or a fixed connection, as described in the second embodiment. This embodiment is not specifically limited to this. Furthermore, the support structure 510 can include only a single extension support, or it can include both an extension support and an elastic hinge, as described in the first embodiment. This embodiment is also not specifically limited to this.

[0088] In some embodiments, the soft cover 523 is made of a soft material, such as a blanket, elastic cloth, rubber, thread, silicone, thermoplastic polyurethane (TPU), thermoplastic elastomer (TPE), thermoplastic rubber (TPR), or other elastic material. The soft material connects the first end of the first cover 521 to the first end of the second cover 522, respectively. For example, the connection can be achieved through a flexible connection or a weakened connection (such as a Lock & Lock weakened structure). When the seat back is reclined, the soft material is in a minimally compressed state. As the seat slides forward or backward or the seat back rotates, the soft material is compressed or relaxed, allowing the second cover 522 to rotate around the first cover 521 under the pressure of the soft material, adaptively adjusting its contact position with the seat back.

[0089] In the fourth embodiment, the first cover plate and the second cover plate are made into an integrated cover plate by using a soft material, which not only can achieve the effect achieved by the seat adjustment device 500 shown in FIG5 , but also can further enhance the aesthetics of the seat structure.

[0090] It should be noted that the above are only exemplary embodiments of the seat adjustment device 500. In practice, the above embodiments may be modified to obtain new embodiments. The following are exemplary embodiments of several possible modifications:

A first cover plate 521 is fixed to one blade of the elastic hinge 512, and a second cover plate 522 is fixed to the other blade of the elastic hinge 512. At the same time, the first cover plate 521 and the second cover plate 522 are combined into a single cover plate by a soft material. In this way, the luggage compartment storage space is not encroached upon during the forward and backward sliding of the seat and the rotation of the seat back, and the gap between the luggage compartment trim and the seat back is covered. At the same time, the appearance is beautiful and elegant, improving the user's visual experience.

The second cover plate 522 is made of elastic material. This ensures that the luggage compartment storage space is not encroached upon during the forward and backward sliding of the seat and the rotation of the seat back, and covers the gap between the luggage compartment trim and the seat back. At the same time, the elastic material can achieve a weight reduction effect.

The first cover plate 521 is sunken into the slot, and the second end b2 of the first cover plate 521 is fixed to one blade of the elastic hinge 512. In this way, the luggage compartment storage space is not encroached upon during the forward and backward sliding of the seat and the rotation of the seat back, and the gap between the trunk trim and the seat back is covered. In addition, the first cover plate is always flush with the trunk trim during the forward and backward sliding of the seat and the rotation of the seat back, ensuring that there is no gap at the contact point between the first cover plate and the trunk trim, thus preventing foreign objects from falling. This is both aesthetically pleasing and practical.

This variation combines the bracket structure design in the above-mentioned embodiment one, the first cover plate design in the above-mentioned embodiment three, and the one-piece cover plate design in the above-mentioned embodiment four. The first cover plate 521 and the second cover plate 522 are combined into an one-piece cover plate 520 through soft material, and an elastic hinge 512 is provided at the second end of the bracket structure 510. One side of the soft material is fixed to one blade of the elastic hinge 512, and the other side of the soft material is fixed to the other blade of the elastic hinge 512, and the side cover plate portion corresponding to the trunk trim is sunk into the groove of the trunk trim. In this way, the luggage compartment storage space is not encroached upon during the seat sliding and seatback rotation process, and the gap between the luggage compartment trim and the seatback is covered. Furthermore, the first cover plate is always flush with the luggage compartment trim plate during the seat sliding and seatback rotation process, ensuring that there is no gap at the contact point between the first cover plate and the luggage compartment trim plate, thus preventing foreign objects from falling. This is both aesthetically pleasing and practical, and also enhances the appearance and visual experience of the user.

The side cover plate portion corresponding to the trunk trim is sunk into the groove of the trunk trim, and one end of the side cover plate is fixed to the seat back. In this way, the storage space of the trunk will not be encroached upon when the seat slides forward and backward and the seat back rotates, and the gap between the trunk trim and the seat back is covered. In addition, the first cover plate can always form the same plane with the trunk trim plate when the seat slides forward and backward and the seat back rotates, ensuring that there is no gap at the contact position between the first cover plate and the trunk trim plate, thus preventing foreign objects from falling. It is beautiful and practical, and can also make the appearance look beautiful and generous, improve the user's visual experience, and can also achieve the effect of weight reduction through elastic materials.
