Description

Technical Field

[0001] This utility model relates to the technical field of mattresses, and in particular to a vehicle-mounted mattress. Background Technology

[0002] With the increasing popularity of cars, car mattresses have become an important piece of equipment for users to rest or camp in their vehicles. The usual way to use them is to lay the back of the rear seats flat, then place the front end of the car mattress on the flat rear seat back, and place the back end in the trunk of the vehicle, thus creating a relatively flat resting surface.

[0003] Figure 1 This is a schematic diagram illustrating the usage of an existing in-vehicle mattress, such as... Figure 1 As shown, the mattress body 100 is placed on and in contact with the vehicle interior structure 200, which includes the front seat 210, the rear seat 220, and the trunk floor 230. Because the mattress body 100 is made of flexible material, the portion in the front gap area 240 is prone to bending downwards under pressure, causing it to collapse and deform under human pressure. This problem results in the human body lacking effective support in the gap area 240 due to the mattress collapsing, severely affecting rest comfort and sleep quality, and also easily leading to irreversible fatigue deformation or damage to the internal structure of the mattress. To solve the above problems, existing technologies typically use independent inflatable support packs 250 to fill the gap area 240 between the rear seat 220 and the front seat 210. In use, first, the backrests of the rear seats 220 are laid flat. Then, the inflatable support pack 250 is placed in the gap area 240 between the rear seats 220 and the front seats 210 and inflated. The top of the inflatable support pack 250 should be flush with the top surface of the rear seat backrest. Next, the front end of the mattress body 100 is placed on the inflatable support pack 250, the rear end on the trunk floor 230, and the middle part is laid flat on the folded-down rear seat backrest. In this way, the front end of the mattress body 100 is effectively supported. While using an independent inflatable support pack 250 to fill the gap area 240 between the seats improves support, it also has significant drawbacks: inflation is required every time it is used, which is cumbersome, takes up valuable rest time, and reduces ease of use. Therefore, the existing support solutions for car mattresses still need improvement, and there is an urgent need for a car mattress that is simple and convenient to operate and provides immediate and effective support. Utility Model Content

[0004] Addressing the shortcomings in support and convenience of existing car mattress products, the purpose of this invention is to provide a car mattress with a simple structure, easy and convenient use and storage, adaptable to different vehicle models with varying seat gaps, and high comfort. The adjustable-width rigid support plate in this invention provides strong and effective support for the mattress body spanning the gap between the rear and front seats, ensuring that the load is effectively transferred to the vehicle seats when the user uses the mattress. This provides a relatively flat, stable, and comfortable support surface, effectively improving the resting support experience. It also meets the application needs of users in multiple scenarios.

[0005] To address the aforementioned technical problems, this utility model discloses a car mattress, placed on the interior structure of a vehicle. The vehicle interior structure includes vehicle seats and a trunk floor. The vehicle seats include rear seats and front seats. The car mattress includes a mattress body and a rigid support plate. The mattress body comprises a first part and a second part. The first part spans the gap between the rear and front seats of the vehicle. The second part is located above the vehicle seats and / or the trunk floor. The rigid support plate is positioned below the first part of the mattress body. This car mattress solution, by placing a rigid support plate below the mattress body, not only simplifies and speeds up the use and storage of the car mattress, significantly improving operational efficiency and user experience, but also provides strong and effective support to the first part of the mattress body spanning the gap between the rear and front seats. This ensures that the load is effectively transferred to the vehicle seats when the user uses the mattress, providing a relatively flat, stable, and comfortable support surface and effectively enhancing the rest support experience.

[0006] In some specific embodiments, the rigid support plate is a single-piece board structure. The car mattress in this solution has a simple and reliable structure, and its assembly and disassembly from the mattress body are extremely convenient during use, requiring no adjustment steps, achieving immediate use and improving user-friendliness. In some specific embodiments, the rigid support plate includes a first rigid support plate, a second rigid support plate, and a telescopic mechanism. The first and second rigid support plates are connected through the telescopic mechanism, and the second rigid support plate can slide relative to the first rigid support plate through the telescopic mechanism. The car mattress in this solution, through the telescopic mechanism, allows for flexible adjustment of the support width of the rigid support plate, facilitating storage after use and reducing storage volume, thereby reducing the space occupied by the rigid support plate after storage. Furthermore, the telescopic rigid support plate can adapt to the support needs of different car seat gap areas, thus meeting the usage needs of different users and scenarios.

[0007] In some specific embodiments, the retractable mechanism is a sliding engagement mechanism, including a slide rail disposed on the first rigid support plate and a slide groove disposed on the second rigid support plate, or it includes a slide groove disposed on the first rigid support plate and a slide rail disposed on the second rigid support plate. The vehicle mattress in this solution features a simple and practical rigid support plate structure. Adjusting the width of the rigid support plate or storing it is simple, convenient, time-saving, and labor-saving for the user. Simultaneously, it allows for flexible adjustment of the rigid support plate's support width, thereby adapting to the support needs of different vehicle models in gap areas and meeting the usage needs of different users and scenarios.

[0008] In some specific embodiments, the rigid support plate includes a locking mechanism, which includes a spring pin and a positioning hole. The vehicle-mounted mattress in this solution provides reliable positioning and locking functions for the retractable mechanism, thereby improving the structural rigidity and overall stability of the retractable mechanism in the unfolded state. This prevents the rigid support plate from unexpectedly retracting or sliding in the unfolded state, ensuring it remains stable. Simultaneously, it also prevents the rigid support plate from automatically unfolding or sliding in the retracted state, guaranteeing stability in the retracted state and reducing wear or damage caused by loosening or shifting of components.

[0009] In some specific embodiments, the rigid support plate includes a third rigid support plate, which is disposed on the side of the first rigid support plate opposite to the second rigid support plate via the telescopic mechanism. The third rigid support plate can slide relative to the first rigid support plate via the telescopic mechanism. In this solution, the car mattress, by adding a third rigid support plate, can further increase the flexible adjustment range of the rigid support plate's support width, enabling it to adapt to the support needs of more types of car seats in gap areas. Moreover, when the total unfolded area of ​​the rigid support plate remains unchanged, the added third rigid support plate in this solution can make the first and second rigid support plates smaller. Therefore, during storage, the rigid support plate can be retracted more compactly, thereby further reducing the storage volume of the rigid support plate and further optimizing the space occupied by the rigid support plate after storage.

[0010] In some specific embodiments, the second and third rigid support plates are arranged parallel to each other above the first rigid support plate, and can slide synchronously or independently relative to the first rigid support plate via the telescopic mechanism along the width direction of the vehicle mattress. The vehicle mattress in this solution features a well-organized, simple, and practical rigid support plate structure. Whether sliding synchronously or independently, it provides flexibility and convenience for users to adjust the support width of the rigid support plate. The operation is simple and convenient, thus adapting to the support needs of different vehicle models in the gap area and meeting the usage needs of different users and scenarios.

[0011] In some specific embodiments, the first rigid support plate includes an upper first rigid support plate, a lower first rigid support plate, and an intermediate body connecting the two. The telescopic mechanism includes a second sliding fit structure disposed between the upper first rigid support plate and the second rigid support plate, and / or a third sliding fit structure disposed between the lower first rigid support plate and the second rigid support plate. The car mattress in this solution features a simple and practical layered rigid support plate structure. It is easy and convenient to operate, saving time and effort, during use or storage. Furthermore, when the rigid support plate is folded up, its overall appearance is more aesthetically pleasing. Simultaneously, it allows for flexible adjustment of the rigid support plate's support width, adapting to the support needs of different car models in gap areas and meeting the usage requirements of different users and scenarios. In addition, this structural type can effectively reduce structural weight while improving the overall rigidity of the rigid support plate.

[0012] In some specific embodiments, the rigid support plate includes a third rigid support plate, which is symmetrically arranged with the second rigid support plate about the middle body of the first rigid support plate. The third rigid support plate and the upper plate of the first rigid support plate and / or the lower plate of the first rigid support plate are respectively provided with sliding fit structures that are symmetrical and identical to the second and third sliding fit structures. In this solution, the car mattress, by adding a third rigid support plate, can further increase the flexible adjustment range of the rigid support plate's support width, enabling it to adapt to the support needs of more types of car seats in the gap area, meeting the usage needs of different users and scenarios. Moreover, when the total unfolded area of ​​the rigid support plate remains unchanged, the third rigid support plate added in this solution can make the first and second rigid support plates smaller. Therefore, when stored, the rigid support plate can be folded more compactly, thereby further reducing the storage volume of the rigid support plate and further optimizing the space occupied by the rigid support plate after storage. Meanwhile, the rigid support plate structure of the vehicle-mounted mattress in this solution is simple and practical, making it easy and convenient for users to use or store, saving time and effort. When the rigid support plate is folded up, its overall appearance is also more aesthetically pleasing. Furthermore, this structural type can further improve the overall rigidity and stability of the rigid support plate in its unfolded state, while effectively reducing structural weight.

[0013] In some specific embodiments, the second sliding fit structure, the third sliding fit structure, and the symmetrically arranged sliding fit structures are all composed of slide rails and slide grooves. The vehicle mattress in this solution features simple and practical sliding fit structures, making operation simple and convenient, saving time and effort during use and storage. Simultaneously, it allows for flexible adjustment of the rigid support plate's support width, adapting to the support needs of different vehicle models' seats in gap areas and meeting the usage needs of different users and scenarios.

[0014] In some specific embodiments, the rigid support plate includes a first snap-fit ​​structure, which includes a snap-fit ​​block extending laterally from the middle body of the first rigid support plate and a snap-fit ​​groove disposed on the second rigid support plate, wherein the snap-fit ​​block and the snap-fit ​​groove are matched with each other. The vehicle mattress in this solution, through the design of the first snap-fit ​​structure, can provide additional lateral constraint and load-bearing transmission path when the rigid support plate is deployed, thereby effectively improving the overall support performance of the rigid support plate.

[0015] In some specific embodiments, the rigid support plate includes a second snap-fit ​​structure, which includes a snap-fit ​​block extending laterally from the middle body of the first rigid support plate and a snap-fit ​​groove disposed on the third rigid support plate, wherein the snap-fit ​​block and the snap-fit ​​groove are mutually matched. The vehicle mattress in this solution, through the design of the second snap-fit ​​structure, can further enhance the additional lateral constraint and load-bearing force transmission path provided when the rigid support plate is deployed, further enhancing the structural stability and bending stiffness of the rigid support plate.

[0016] In some specific embodiments, the rigid support plate includes a first rigid support plate, a second rigid support plate, and a flexible connector. The first rigid support plate and the second rigid support plate are connected to each other through the flexible connector. In this solution, the vehicle-mounted mattress can unfold or fold the rigid support plates, improving user convenience, saving time and effort. Furthermore, after folding and folding, the storage volume of the rigid support plates is reduced, thereby minimizing the space occupied by the folded rigid support plates and improving portability.

[0017] In some specific embodiments, the flexible connector is a connecting rope, and the first and second rigid support plates are provided with through holes for the connecting rope to pass through. In this vehicle-mounted mattress, the connecting rope allows the user to easily unfold or fold the rigid support plates for storage, improving user convenience, saving time and effort. After folding and storing, the storage volume of the rigid support plates is reduced, thereby reducing the space occupied by the rigid support plates after storage. The user operation is simple, convenient, and practical.

[0018] In some specific embodiments, the flexible connector is a flexible connecting substrate, and the first rigid support plate and the second rigid support plate are fixed to the flexible connecting substrate at intervals. In this solution, the flexible connecting substrate of the car mattress can act as a hinge and cover during the folding process for storage, maintaining the connection relationship of each rigid support plate while preventing mutual collision and wear. At the same time, through the flexible connecting substrate, users can easily unfold or fold each rigid support plate for storage, improving the convenience of user operation and saving time and effort. After folding and storage, the storage volume of the rigid support plates is reduced, thereby reducing the space occupied by the rigid support plates after storage, making it convenient for users to store and carry.

[0019] In some specific embodiments, the flexible connector has preset folding lines in the interval area between the first, second, and third rigid support plates. In this solution, the preset folding lines guide the rigid support plates to fold along a predetermined trajectory and direction, greatly improving the folding accuracy of each rigid support plate during storage and making storage more time-saving and labor-saving. At the same time, standardized folding also helps extend the service life of the flexible connector.

[0020] In some specific embodiments, the flexible connector is a hinge, and the first rigid support plate and the second rigid support plate are hinged together by the hinge. In this solution, the vehicle mattress allows users to easily unfold or fold the rigid support plates for storage, improving user convenience and saving time and effort. After folding and storing, the storage volume of the rigid support plates is reduced, thereby minimizing the space occupied by the rigid support plates after storage, making it convenient for users to store and carry, and practical.

[0021] In some specific embodiments, the hinge is equipped with a multi-position angle locking mechanism, through which the rigid support plate is locked in a flat state or a specific tilt angle. The vehicle mattress in this solution allows the rigid support plate to be stably positioned in a flat support state or a backrest state at a specific angle, expanding the functionality of the vehicle mattress and meeting various rest needs such as sitting and reclining.

[0022] In some specific embodiments, the rigid support plate includes a third rigid support plate, which is disposed on the side of the first rigid support plate opposite to the second rigid support plate via the flexible connector. The third rigid support plate is connected to the first rigid support plate through the flexible connector. The car mattress in this solution further increases the support area of ​​the rigid support plate, making the folded and stored shape more regular and improving user flexibility and storage convenience. Furthermore, by adding a third rigid support plate, the car mattress in this solution can further increase the flexible adjustment range of the rigid support plate's support width, enabling it to adapt to the support needs of more types of car seats in gap areas, meeting the usage needs of different users and scenarios. Moreover, when the total unfolded area of ​​the rigid support plate remains unchanged, the added third rigid support plate in this solution makes the first and second rigid support plates smaller. Therefore, during storage, the rigid support plate can be folded more compactly, further reducing the storage volume of the rigid support plate and further optimizing the space occupied by the rigid support plate after storage.

[0023] In some specific embodiments, the lower surface of the mattress body is provided with a receiving structure, which can accommodate and fix the rigid support plate. The vehicle-mounted mattress in this solution, through its receiving structure design, maintains the relative positional stability of the rigid support plate and the mattress body while also ensuring ease of assembly and disassembly, effectively improving the user experience and reliability of the product.

[0024] In some specific embodiments, the accommodating structure is one of the following: a storage bag, a zipper, a rope structure, or a cord. The vehicle-mounted mattress in this solution features a simple and easy-to-manufacture accommodating structure, low cost, and high practicality. It maintains the relative positional stability of the rigid support plate and the mattress body while also ensuring ease of assembly and disassembly, effectively improving product functionality and optimizing user experience and reliability.

[0025] In some specific embodiments, the outer contour of the rigid support plate is covered with a flexible protective material, and / or its bottom and / or sides are provided with an anti-slip structure. The vehicle mattress in this solution can effectively prevent the rigid support plate from shifting during use, improving the stability of the vehicle mattress during use.

[0026] In some specific embodiments, the vehicle mattress includes a pull strap, a rotating component, and a motor. One end of the pull strap is fixed to the first part of the mattress body or the lower surface of the rigid support plate. The rotating component is disposed on the vehicle seat, and a through space is provided below the rotating component for the pull strap to pass through. The other end of the pull strap passes through the through space below the rotating component and connects to the motor. This vehicle mattress solution enables automatic unfolding and folding of the vehicle mattress, making it more convenient and time-saving for users.

[0027] In some specific embodiments, the mattress body is filled with stretchable foam, which is formed by multiple interconnected geometric foam blocks. In this vehicle-mounted mattress, the stretchable foam possesses excellent compressibility and deformation capacity. This allows the mattress body to be compressed to a smaller volume when stored, significantly improving the convenience of storage and reducing the space occupied.

[0028] This utility model also discloses a car mattress, placed on the interior structure of a vehicle, the vehicle interior structure including vehicle seats and a trunk floor, the vehicle seats including rear seats and front seats.

[0073] Figure 2A This is a schematic diagram illustrating the usage state of one embodiment of the vehicle-mounted mattress of this application. Figure 2B This is a schematic diagram of the structure of one embodiment of the vehicle-mounted mattress of this application. Figure 2A and Figure 2BAs shown, the car mattress 10 is suitable for use inside a vehicle. In use, the car mattress 10 is placed on and in contact with the vehicle's interior structure 200. The vehicle interior structure 200 includes vehicle seats and a trunk floor 230. The vehicle seats include front seats 210 and rear seats 220. The car mattress 10 includes a mattress body 100 and a rigid support plate 300. The mattress body 100 includes a first part 110 and a second part 120. The rigid support plate 300 corresponds to the first part 110 of the mattress body 100, and the second part 120 is integrally connected to the first part 110. The rigid support plate 300 is disposed below the mattress body 100 and adheres to the lower surface of the mattress body 100. In other embodiments of this example, the rigid support plate 300 may also be embedded inside the mattress body 100. To provide more ample resting space, the mattress body 100 of the in-vehicle mattress 10 extends forward, with its front end extending beyond the top surface of the folded-down rear seat 220 and across the gap area 240 between the rear seat 220 and the front seat 210. The mattress body 100 is made of a flexible, airtight material and has air vents. The first portion 110 of the mattress body 100, covered by a rigid support plate 300, spans across the gap area 240 between the rear seat 220 and the front seat 210. The second portion 120 may be located above the front seat 210 and / or the rear seat 220 and / or the trunk floor 230. The rigid support plate 300 is made of a lightweight, high-strength material, which may be selected from one or more combinations of honeycomb panels, carbon fiber composites, aluminum alloy profiles, PP plastic sheets, wood panels, or plywood. A rigid support plate 300 is disposed below the mattress body 100 and fits against the lower surface of the mattress body 100, thus giving the mattress body 100 a first part 110 with stable structure and good support performance. The length of the first part 110 of the vehicle mattress 10 can be designed according to actual needs, as long as a portion of the first part 110 is located on and supported by the backrest of the rear seat 220 of the vehicle. For example, along the first direction (such as the length direction of the vehicle mattress 10), approximately 1 / 3 of the total size of the first part 110 is located on the backrest of the rear seat 220 of the vehicle and contacts the top surface of the backrest of the rear seat 220, while the remaining 2 / 3 is suspended, covering the gap area 240 between the rear seat 220 and the front seat 210 of the vehicle. When a user rests using the car mattress 10, a part of the user's body is located on the first part 110, such as the head and shoulders of the user's body. At this time, the user's shoulders exert pressure on the part of the first part 110 of the car mattress 10 located on the back of the rear seat 220 of the vehicle, and the user's head exerts pressure on the part of the first part 110 of the mattress body 10 located in the gap area 240 between the rear seat 220 and the front seat 210 of the vehicle.Because the first part 110 of the car mattress 10 effectively transfers the load to the rear seat 220 and / or the front seat 210 of the vehicle through the rigid support plate 300, the first part 110 of the mattress body 100 supporting the user's head will not bend or deform. The user can obtain a relatively flat, stable, and comfortable support surface on the first part 110, effectively improving the rest support experience. This ensures that the load is effectively transferred to the vehicle seat when the user uses the car mattress, thereby providing the user with a relatively flat, stable, and comfortable support surface, effectively improving the rest support experience.

Figure 3 As shown, the rigid support plate 300 in this embodiment is a single-piece board structure. In this embodiment, the rigid support plate 300 has a simple and reliable structure. During use, the assembly and disassembly of the rigid support plate 300 and the mattress body 100 of the vehicle-mounted mattress 10 are extremely convenient, requiring no adjustment steps, achieving immediate use and improving user-friendliness. In this embodiment, the rigid support plate 300 can be made of lightweight, high-strength materials, which can be, but are not limited to, one or more combinations of honeycomb panels, carbon fiber composite materials, aluminum alloy profiles, PP plastic sheets, wood panels, or plywood.

[0075] Figure 4 For this application Figure 2B A three-dimensional structural schematic diagram of another embodiment of the rigid support plate of the vehicle-mounted mattress. Figure 5 For this application Figure 4 A schematic diagram of the rigid support plate in its deployed state. Figure 4 and Figure 5 As shown, in this embodiment, the rigid support plate 300 includes a first rigid support plate 310, a second rigid support plate 320, a third rigid support plate 330, and a telescopic mechanism 340 connecting each support plate. The second rigid support plate 320 and the third rigid support plate 330 are arranged parallel above the first rigid support plate 310 and can slide synchronously or independently relative to the first rigid support plate 310 along the second direction (the width direction of the vehicle mattress 10) through the telescopic mechanism 340. This allows the rigid support plate 300 to expand and contract in the width direction of the vehicle mattress 10, enabling flexible adjustment of the support width of the rigid support plate 300. This facilitates the storage of the rigid support plate after use, reducing its storage volume and thus minimizing the space occupied by the rigid support plate after storage. Furthermore, the telescopic rigid support plate 300 can adapt to the support needs of different vehicle models' seats in the gap area, meeting the usage needs of different users and scenarios. In this embodiment, specifically, as shown... Figure 5As shown, the telescopic mechanism 340 in this embodiment is a first sliding fit structure 341, which includes a first slide rail 3411 and a first slide groove 3412. The first slide groove 3412 is fixedly disposed on both sides of the edge region of the first rigid support plate 310; the first slide rail 3411 is correspondingly disposed on the bottom of the second rigid support plate 320 and the third rigid support plate 330, and forms a sliding fit with the first slide groove 3412. Through the cooperation of the slide rail and the slide groove, the second rigid support plate 320 and the third rigid support plate 330 can extend and retract smoothly and linearly. In other embodiments of this embodiment, the positions of the first slide rail 3411 and the first slide groove 3412 can be interchanged, that is, the first slide rail 3411 is fixedly disposed on both sides of the edge region of the first rigid support plate 310; the first slide groove 3412 is correspondingly disposed on the bottom of the second rigid support plate 320 and the third rigid support plate 330. Preferably, the second rigid support plate 320 and the third rigid support plate 330 are equal in size and symmetrical in structure, so that the rigid support plate 300 is subjected to uniform force when unfolded and the support area is adjustable, thereby adapting to the support needs of different vehicle seat gap areas. It should be noted that in other embodiments of this example, the second rigid support plate 320 and the third rigid support plate 330 are arranged parallel to each other above the first rigid support plate 310, and can also slide synchronously or independently relative to the first rigid support plate 310 along the first direction (i.e., the length direction of the vehicle mattress 10) through the telescopic mechanism 340. This is equivalent to sliding the second rigid support plate 320 and the third rigid support plate 330 synchronously or independently relative to the first rigid support plate 310 along a direction perpendicular to the aforementioned second direction through the telescopic mechanism 340. In addition, in other embodiments, the second rigid support plate 320 and the third rigid support plate 330 can also slide synchronously or independently relative to the first rigid support plate 310 along a direction at any angle to the first direction, as long as the support needs of the vehicle seat gap area can be met during use. Its structural design has high flexibility and adaptability. Furthermore, in other embodiments of this example, the rigid support plate 300 may also be a double-plate telescopic structure comprising only the first rigid support plate 310 and the second rigid support plate 320, without the third rigid support plate 330. The telescopic principle and connection method of this simplified structure are the same as the aforementioned three-plate structure, and will not be described again here.In this embodiment, compared with the double-plate telescopic structure where the rigid support plate 300 only includes the first rigid support plate 310 and the second rigid support plate 320, the aforementioned three-plate structure of the vehicle mattress 10, by adding a third rigid support plate 330, can further increase the flexible adjustment range of the support width of the rigid support plate 300, enabling it to adapt to the support needs of more types of vehicle seats in the gap area and meet the usage needs of different users and scenarios. Moreover, when the total unfolded area of ​​the rigid support plate 300 remains unchanged, the third rigid support plate 300 added in this solution can make the first rigid support plate 310 and the second rigid support plate 320 smaller. Therefore, when stored, the rigid support plate 300 can be folded more compactly, thereby further reducing the storage volume of the rigid support plate 300 and further optimizing the space occupied by the rigid support plate 300 after storage.

[0076] Figure 6A For this application Figure 5 A schematic diagram of the cross-sectional structure of the rigid support plate along line AA. Figure 6B For this application Figure 6A A cross-sectional schematic diagram of the medium-rigidity support plate in a locked state. (See diagram below.) Figure 5 , Figure 6A and Figure 6BAs shown, in this embodiment, the rigid support plate 300 further includes a locking mechanism 800, which includes a spring pin 810, a button 820, a connector 830, and a positioning hole 840. The spring pin 810, button 820, and connector 830 are disposed on the first rigid support plate 310. The button 820 is fixedly connected to the spring pin 810 via the connector 830. Preferably, an elastic element (such as a spring) is provided below the spring pin 810 to provide a continuous upward restoring force. The positioning hole 840 is disposed on the second rigid support plate 320 and / or the third rigid support plate 330. The positioning hole 840 can be a blind hole or a through hole. When the user needs to unfold the rigid support plate 300, a lateral pulling force is applied to slide the second rigid support plate 320 and / or the third rigid support plate 330 relative to the first rigid support plate 310 to a predetermined position. Specifically, when the spring pin 810 aligns with the positioning hole 840, the spring pin 810 springs upward under the elastic force of the lower elastic element (such as a spring) and engages with the positioning hole 840, thereby locking the second rigid support plate 320 and / or the third rigid support plate 330 relative to the first rigid support plate 310. When it is necessary to retract the rigid support plate 300, downward pressure is applied to the button 820. This pressure is transmitted to the spring pin 810 through the connector 830, causing it to move downward and exit the positioning hole 840. While the button 820 is pressed, a lateral pushing force can then be applied to retract the second rigid support plate 320 and / or the third rigid support plate 330. The locking mechanism 800 effectively locks the second rigid support plate 320 and / or the third rigid support plate 330 in the desired sliding position, providing reliable positioning and locking functions for the telescopic mechanism 340. This improves the structural rigidity and overall stability of the telescopic mechanism 340 in the unfolded state, preventing accidental retraction and sliding of the rigid support plate 300 in the unfolded state. It also ensures the rigid support plate 300 remains stable in the unfolded state and prevents it from unfolding or sliding on its own in the retracted state, guaranteeing stability in the retracted state and reducing wear or damage caused by loosening or shifting of components in the telescopic mechanism 340. In this embodiment, the telescopic mechanism 340 includes a first sliding fit structure 341. In other embodiments of this embodiment, it is understood that the locking mechanism 800 is not limited to the above configuration. In an optional embodiment, the locking mechanism 800 may consist only of a spring pin 810 and a positioning hole 840. When the positioning hole 840 is a through hole, after the spring pin 810 is engaged, downward pressure can be applied directly through the through hole (e.g., using a tool or finger) to disengage the spring pin 810 from the positioning hole 840 to unlock it.In another alternative embodiment, the spring pin 810, button 820, and connector 830 can be disposed on the second rigid support plate 320 and / or the third rigid support plate 330, while the positioning hole 840 is correspondingly disposed on the first rigid support plate 310. The working principle is the same as described above and will not be repeated here. Furthermore, the overall structure of the locking mechanism 800 is not limited to the form disclosed in this embodiment. Any similar locking structure based on the cooperation of the spring pin 810 and the positioning hole 840 should be included within the scope of protection of this application.

Figure 8 For this application Figure 7 A schematic diagram of the unfolded state of the rigid support plate. Figure 9A For this application Figure 8 A schematic cross-sectional view of the rigid support plate along line AA. Figure 7 , Figure 8 and Figure 9AAs shown, in this embodiment, the rigid support plate 300 includes a first rigid support plate 310, a second rigid support plate 320, a third rigid support plate 330, and a telescopic mechanism 340. The first rigid support plate 310 includes an upper first rigid support plate 311, a lower first rigid support plate 312, and an intermediate first rigid support plate 313 connecting the two. Preferably, the upper first rigid support plate 311, the intermediate first rigid support plate 313, and the lower first rigid support plate 312 together form a stable "I"-shaped cross-section structure. This type of structure can effectively reduce the structural weight while improving the overall rigidity. It is simple and convenient to operate, saving time and effort when used or stored by the user. Moreover, when the rigid support plate 300 is stored in its stowed state, the overall appearance of the rigid support plate 300 is more aesthetically pleasing. The second rigid support plate 320 and the third rigid support plate 330 are respectively disposed in the suspended areas on both sides of the first rigid support plate 310. They can slide synchronously or independently relative to the first rigid support plate 310 along the second direction (the width direction of the vehicle mattress 10) via the telescopic mechanism 340. This allows for flexible adjustment of the support width of the rigid support plate 300, thereby adapting to the support needs of different vehicle models in the gap area and meeting the usage needs of different users and scenarios. It should be noted that in other embodiments of this example, the second rigid support plate 320 and the third rigid support plate 330 are respectively disposed in the suspended areas on both sides of the first rigid support plate 310. They can also slide synchronously or independently relative to the first rigid support plate 310 along the first direction (i.e., the length direction of the vehicle mattress 10) via the telescopic mechanism 340. This is equivalent to sliding the second rigid support plate 320 and the third rigid support plate 330 synchronously or independently relative to the first rigid support plate 310 along a direction perpendicular to the aforementioned second direction via the telescopic mechanism 340. Furthermore, in other embodiments, the second rigid support plate 320 and the third rigid support plate 330 can also slide synchronously or independently relative to the first rigid support plate 310 along directions at any angle to the first direction, as long as they can meet the support requirements of the vehicle seat gap area during use. Their structural design offers high flexibility and adaptability. In this embodiment, the telescopic mechanism 340 includes a second sliding fit structure 342 and / or a third sliding fit structure 343. (Refer to...) Figure 9AThe second sliding fit structure 342 is disposed between the upper plate 311 of the first rigid support plate and the second rigid support plate 320, and the third sliding fit structure 343 is disposed between the lower plate 312 of the first rigid support plate and the second rigid support plate 320. Specifically, the telescopic mechanism 340 in this embodiment consists of the second sliding fit structure 342 and the third sliding fit structure 343. The second sliding fit structure 342 includes a second slide rail 3421 and a second slide groove 3422, and the third sliding fit structure 343 includes a third slide rail 3431 and a third slide groove 3432. The second slide groove 3422 is fixedly disposed on both sides of the lower surface of the upper plate 311 of the first rigid support plate; the second slide rail 3421 is correspondingly disposed on the upper surface of the second rigid support plate 320 and forms a sliding fit with the second slide groove 3422. The third slide groove 3432 is fixedly disposed on both sides of the upper surface of the lower plate 312 of the first rigid support plate; the third slide rail 3431 is correspondingly disposed on the lower surface of the second rigid support plate 320 and forms a sliding fit with the third slide groove 3432. Through the cooperation of the slide rail and the slide groove, the second rigid support plate 320 can extend and retract smoothly and linearly relative to the first rigid support plate 310. In other embodiments of this example, the positions of the second slide rail 3421 and the second slide groove 3422 can be interchanged. That is, the second slide rail 3421 is fixedly disposed on both sides of the lower surface edge region of the upper plate 311 of the first rigid support plate, and the second slide groove 3422 is correspondingly disposed on the upper surface of the second rigid support plate 320, forming a sliding fit with the second slide rail 3421. Alternatively, the positions of the third slide rail 3431 and the third slide groove 3432 can be interchanged. That is, the third slide rail 3431 is fixedly disposed on both sides of the upper surface edge region of the lower plate 312 of the first rigid support plate, and the third slide groove 3432 is correspondingly disposed on the lower surface of the second rigid support plate 320, forming a sliding fit with the third slide rail 3431. Correspondingly, on the other side of the first rigid support plate 310, the third rigid support plate 330 and the second rigid support plate 320 are symmetrically disposed about the middle body 313 of the first rigid support plate, and the same sliding fit structure is used to realize the telescopic movement. Preferably, the second rigid support plate 320 and the third rigid support plate 330 are equal in size and symmetrical in structure, so that the rigid support plate 300 is subjected to uniform force when unfolded, and the support width can be flexibly adjusted, thereby adapting to the support needs of different vehicle models' seats in the gap area. Preferably, the second sliding fit structure 342, the third sliding fit structure 343, and the symmetrically arranged sliding fit structures are all composed of slide rails and slide grooves, forming a double sliding guide mechanism. The second rigid support plate 320 and the third rigid support plate 330 respectively achieve smooth and synchronous telescopic sliding through their corresponding sliding fit structures, ensuring that the rigid support plate 300 has sufficient overall rigidity and stability in the unfolded state.

Figure 9C For this application Figure 9B A cross-sectional schematic diagram of the medium-rigidity support plate in a locked state. (See diagram below.) Figure 8 , Figure 9B and Figure 9CAs shown, in this embodiment, the rigid support plate 300 further includes a locking mechanism 800, which includes a spring pin 810, a button 820, a connector 830, and a positioning hole 840. The spring pin 810, button 820, and connector 830 are disposed on the first rigid support plate 310. The button 820 is fixedly connected to the spring pin 810 via the connector 830. Preferably, an elastic element (such as a spring) is provided below the spring pin 810 to provide a continuous upward restoring force. The positioning hole 840 is disposed on the second rigid support plate 320 and / or the third rigid support plate 330. The positioning hole 840 can be a blind hole or a through hole. When the user needs to unfold the rigid support plate 300, a lateral pulling force is applied to slide the second rigid support plate 320 and / or the third rigid support plate 330 relative to the first rigid support plate 310 to a predetermined position. Specifically, when the spring pin 810 aligns with the positioning hole 840, the spring pin 810 springs upward under the elastic force of the lower elastic element (such as a spring) and engages with the positioning hole 840, thereby locking the second rigid support plate 320 and / or the third rigid support plate 330 relative to the first rigid support plate 310. When it is necessary to retract the rigid support plate 300, downward pressure is applied to the button 820. This pressure is transmitted to the spring pin 810 through the connector 830, causing it to move downward and exit the positioning hole 840. While the button 820 is pressed, a lateral pushing force can then be applied to retract the second rigid support plate 320 and / or the third rigid support plate 330. The locking mechanism 800 effectively locks the second rigid support plate 320 and / or the third rigid support plate 330 in the desired sliding position, providing reliable positioning and locking functions for the telescopic mechanism 340. This improves the structural rigidity and overall stability of the telescopic mechanism 340 in the deployed state and reduces wear or damage caused by loosening or shifting of components in the telescopic mechanism 340. In this embodiment, the telescopic mechanism 340 includes a second sliding fit structure 342 and / or a third sliding fit structure 343 and symmetrically arranged sliding fit structures. In other embodiments of this embodiment, it is understood that the locking mechanism 800 is not limited to the above configuration. In an optional embodiment, the locking mechanism 800 may consist only of a spring pin 810 and a positioning hole 840. When the positioning hole 840 is a through hole, after the spring pin 810 is engaged, downward pressure can be applied directly through the through hole (e.g., using a tool or finger) to disengage the spring pin 810 from the positioning hole 840 to unlock it. In another alternative embodiment, the spring pin 810, button 820 and connector 830 may be disposed on the second rigid support plate 320 and / or the third rigid support plate 330, and the positioning hole 840 may be disposed on the first rigid support plate 310 accordingly. The working principle is the same as described above and will not be repeated here.Furthermore, the overall structure of the locking mechanism 800 is not limited to the form disclosed in this embodiment. Any similar locking structure based on the engagement of the spring pin 810 and the positioning hole 840 should be included within the protection scope of this application. In other embodiments, the second sliding fit structure 342, the third sliding fit structure 343, and the symmetrically arranged sliding fit structures can also adopt other fit forms that can achieve relatively linear sliding, including but not limited to slider and slide rod, linear guide rail, or ball bearing slide rail, etc., all of which are within the protection scope of this application. In other embodiments of this embodiment, the rigid support plate 300 can also be simplified to a double-plate telescopic structure that only includes the first rigid support plate 310 and the second rigid support plate 320, without the third rigid support plate 330. The telescopic principle and connection method of this simplified structure are the same as the aforementioned three-plate structure, and will not be repeated here. In this embodiment, compared with the double-plate telescopic structure where the rigid support plate 300 only includes the first rigid support plate 310 and the second rigid support plate 320, the aforementioned three-plate structure of the vehicle mattress 10, by adding a third rigid support plate 330, can further increase the flexible adjustment range of the support width of the rigid support plate 300, enabling it to adapt to the support needs of more types of vehicle seats in the gap area and meet the usage needs of different users and scenarios. Moreover, when the total unfolded area of ​​the rigid support plate 300 remains unchanged, the third rigid support plate 300 added in this solution can make the first rigid support plate 310 and the second rigid support plate 320 smaller. Therefore, when stored, the rigid support plate 300 can be folded more compactly, thereby further reducing the storage volume of the rigid support plate 300 and further optimizing the space occupied by the rigid support plate 300 after storage.

[0079] Figure 10 For this application Figure 2B A half-sectional view of another embodiment of the medium-rigidity support plate. See also... Figure 10 In this application, the rigid support plate 300 in this embodiment is as follows: Figures 7 to 9CThe structure of the rigid support plate 300 described in the previous section is similar, and the identical parts will not be repeated. The only difference is that the rigid support plate 300 in this embodiment further includes a first snap-fit ​​structure 350. The first snap-fit ​​structure 350 includes a first snap block 351 extending laterally from the intermediate body 313 of the first rigid support plate, and a first snap groove 352 disposed on the second rigid support plate 320. The first snap block 351 and the first snap groove 352 match each other and form a snap-fit ​​engagement, which can provide additional lateral constraints and load-bearing force transmission paths when the rigid support plate 300 is unfolded, thereby effectively improving the overall support performance of the first rigid support plate 310 and further enhancing the structural stability and bending stiffness of the rigid support plate 300. Symmetrically, a second snap-fit ​​structure (not shown in the figure) is also correspondingly disposed on the intermediate body 313 of the first rigid support plate on one side of the third rigid support plate 330, and its construction is the same as that of the first snap-fit ​​structure 350. The first snap-fit ​​structure 350 and the second snap-fit ​​structure work together to further enhance the structural stability and bending stiffness of the rigid support plate 300 in the double-sided extended state. It should be noted that in other embodiments of this example, the second rigid support plate 320 and the third rigid support plate 330 are respectively disposed in the suspended areas on both sides of the first rigid support plate 310. They can also slide synchronously or independently relative to the first rigid support plate 310 along the first direction (i.e., the length direction of the vehicle mattress 10) via the telescopic mechanism 340. This is equivalent to sliding the second rigid support plate 320 and the third rigid support plate 330 synchronously or independently relative to the first rigid support plate 310 along a direction perpendicular to the aforementioned second direction via the telescopic mechanism 340. Furthermore, in other embodiments, the second rigid support plate 320 and the third rigid support plate 330 can also slide synchronously or independently relative to the first rigid support plate 310 along a direction at any angle to the first direction, as long as the support requirements of the vehicle seat gap area can be met during use. Its structural design has high flexibility and adaptability.

[0080] Figure 11 For this application Figure 2B A schematic diagram of another embodiment of the rigid support plate of the vehicle-mounted mattress. (See diagram below.) Figure 11As shown, in this embodiment, the rigid support plate 300 includes a first rigid support plate 310, a second rigid support plate 320, a third rigid support plate 330, and a connecting rope 360. Each support plate is provided with a through hole 361 through which the connecting rope 360 ​​can pass. Through the cooperation of the connecting rope 360 ​​and the through hole 361, the second rigid support plate 320 and the third rigid support plate 330 are flexibly and fixedly connected to the first rigid support plate 310, forming a modular structure that can be separated and combined. Specifically, the connecting rope 360 ​​is made of flexible and durable materials such as high-strength nylon rope or braided tape, and passes through the pre-set through holes 361 on each support plate in sequence to form a closed-loop connection structure. The through hole 361 can be set at the corners or sides of each rigid support plate, etc., where stress is applied, and its inner edge can be provided with a wear-resistant bushing to reduce wear on the connecting rope during installation and use. By adjusting the length of the connecting rope 360 ​​and the layout of the through holes, sufficient folding freedom can be provided while ensuring that the rigid support plate 300 maintains relative positional stability when unfolded. In use, the user can unfold and lay the rigid support plate 300 flat to form a continuous rigid support plane. When storing after use, the user only needs to fold the second rigid support plate 320 and the third rigid support plate 330 along the constraint direction of the connecting rope 360 ​​and stack them on top of the first rigid support plate 310, thereby achieving compact storage of the overall structure and improving portability in limited spaces such as vehicle trunks. In other embodiments of this example, the rigid support plate 300 may also be a double-plate folding structure including only the first rigid support plate 310 and the second rigid support plate 320, without the third rigid support plate 330. In this embodiment, compared to the double-plate folding structure where the rigid support plate 300 only includes the first rigid support plate 310 and the second rigid support plate 320, the aforementioned three-plate structure of the vehicle mattress 10, by adding a third rigid support plate 330, can further increase the flexible adjustment range of the support width of the rigid support plate 300, enabling it to adapt to the support needs of more types of vehicle seats in the gap area and meet the usage needs of different users and scenarios. Moreover, when the total unfolded area of ​​the rigid support plate 300 remains unchanged, the third rigid support plate 300 added in this solution can make the first rigid support plate 310 and the second rigid support plate 320 smaller. Therefore, when stored, the rigid support plate 300 can be folded more compactly, thereby further reducing the storage volume of the rigid support plate 300 and further optimizing the space occupied by the rigid support plate 300 after storage. In other embodiments of this embodiment, the structure may also have more than three rigid support plates. The perforation arrangement, connecting rope threading method, and folding principle of this type of structure are the same as those of the aforementioned three-plate structure. All of them achieve the functions of unfolding support and folding storage through flexible connection, which will not be elaborated here.

[0081] Figure 12 For this application Figure 2BA schematic diagram of another embodiment of the rigid support plate of the vehicle-mounted mattress. (See diagram below.) Figure 12As shown, in this embodiment, the rigid support plate 300 includes a first rigid support plate 310, a second rigid support plate 320, a third rigid support plate 330, and a flexible connecting substrate 370. The second rigid support plate 320 and the third rigid support plate 330 are fixedly connected to the first rigid support plate 310 via the flexible connecting substrate 370. Specifically, the first rigid support plate 310, the second rigid support plate 320, and the third rigid support plate 330 are fixed to the flexible connecting substrate 370 by welding, bonding, or high-frequency pressing in a parallel and spaced manner, forming an integral foldable plate structure. The flexible connecting substrate 370 can be made of high-strength Oxford cloth, nylon fabric, or rubber composite material, possessing good tensile strength and fatigue resistance. Pre-set folding lines can be provided in the interval areas between the first rigid support plate 310, the second rigid support plate 320, and the third rigid support plate 330, allowing each rigid support plate to fold orderly along the folding lines, improving the folding accuracy of each rigid support plate during folding and storage, and saving time and effort when storing the folded rigid support plates. In use, the rigid support plates unfold and are arranged flush. The flexible connecting substrate 370 provides continuous bottom support for the overall structure of the rigid support plate 300, ensuring the integrity and stability of the supporting plane of the rigid support plate 300. When storing, the user can sequentially flip and stack the second rigid support plate 320 and the third rigid support plate 330 onto the first rigid support plate 310 along the fold lines between adjacent rigid support plates. This operation is simple, easy to carry, and convenient to use. The flexible connecting substrate 370 acts as a hinge and covering during the folding process, maintaining the connection between the rigid support plates while preventing mutual collision and wear. Furthermore, in other embodiments of this example, the rigid support plate 300 may also be a double-plate folding structure including only the first rigid support plate 310 and the second rigid support plate 320, without the third rigid support plate 330. In this embodiment, compared to the double-plate folding structure where the rigid support plate 300 only includes the first rigid support plate 310 and the second rigid support plate 320, the aforementioned three-plate structure of the vehicle mattress 10, by adding a third rigid support plate 330, can further increase the flexible adjustment range of the support width of the rigid support plate 300, enabling it to adapt to the support needs of more types of vehicle seats in the gap area and meet the usage needs of different users and scenarios. Moreover, when the total unfolded area of ​​the rigid support plate 300 remains unchanged, the third rigid support plate 300 added in this solution can make the first rigid support plate 310 and the second rigid support plate 320 smaller. Therefore, when stored, the rigid support plate 300 can be folded more compactly, thereby further reducing the storage volume of the rigid support plate 300 and further optimizing the space occupied by the rigid support plate 300 after storage. In other embodiments, there may also be a structure with more than three rigid support plates. The folding principle and connection method of this type of structure are the same as the aforementioned three-plate structure, and will not be described again here.

[0082] Figure 13 For this application Figure 2B A schematic diagram of another embodiment of the rigid support plate of the vehicle-mounted mattress. (See diagram below.) Figure 13As shown, in this embodiment, the rigid support plate 300 includes a first rigid support plate 310, a second rigid support plate 320, a third rigid support plate 330, and a hinge 380. The second rigid support plate 320 and the third rigid support plate 330 are respectively hinged and fixedly connected to the left and right sides of the first rigid support plate 310 via the hinge 380, forming a multi-segment foldable plate assembly that can be unfolded as an overall support plane and can also be folded for storage. Preferably, the mounting surface of the hinge 380 between the third rigid support plate 330 and the first rigid support plate 310, and the mounting surface of the hinge 380 between the second rigid support plate 320 and the first rigid support plate 310, are located on the upper and lower outer surfaces of the rigid support plate 300, respectively, i.e., they are arranged back to back. This design allows the first rigid support plate 310, the second rigid support plate 320, and the third rigid support plate 330 to naturally form a compact "Z"-shaped folding structure when folded sequentially in the same direction, through the rotation of the hinge 380, greatly reducing the overall volume in the stored state. In other embodiments, the mounting surfaces of the hinge 380 between the third rigid support plate 330 and the first rigid support plate 310, and the mounting surfaces of the hinge 380 between the second rigid support plate 320 and the first rigid support plate 310, can also be located simultaneously on the upper or lower surface of the rigid support plate 300, i.e., both are located on the same surface of the rigid support plate 300. The hinge 380 can be made of high-strength metal, with its leaves fixed to the mating edges of adjacent rigid support plates. Preferably, the hinge 380 can be provided with a multi-position angle locking mechanism, so that the rigid support plate 300 can be stably in a flat support state or a backrest state at a specific angle, meeting the user's various rest needs such as sitting or reclining. This structure keeps the rigid support plate 300 flat when unfolded, providing a continuous support plane and thus providing stable rigid support; when storing after use, the user can rotate the second rigid support plate 320 and the third rigid support plate 330 around the hinge 380 axis and fold and stack them sequentially on the first rigid support plate 310, which is simple to operate, easy to carry, and convenient to use. Furthermore, in other embodiments of this example, the rigid support plate 300 may also be a double-plate folding structure that includes only the first rigid support plate 310 and the second rigid support plate 320, without providing the third rigid support plate 330.In this embodiment, compared to the double-plate folding structure where the rigid support plate 300 only includes the first rigid support plate 310 and the second rigid support plate 320, the aforementioned three-plate structure of the vehicle mattress 10, by adding a third rigid support plate 330, can further increase the flexible adjustment range of the support width of the rigid support plate 300, enabling it to adapt to the support needs of more types of vehicle seats in the gap area and meet the usage needs of different users and scenarios. Moreover, when the total unfolded area of ​​the rigid support plate 300 remains unchanged, the addition of the third rigid support plate 300 in this solution can make the first rigid support plate 310 and the second rigid support plate 320 smaller. Therefore, when stored, the rigid support plate 300 can be folded more compactly, thereby further reducing the storage volume of the rigid support plate 300 and further optimizing the space occupied by the rigid support plate 300 after storage. In other embodiments, the structure may also have more than three rigid support plates. This type of structure also uses hinge 380 to achieve the hinge and angle adjustment between the rigid support plates. Its folding principle and connection method are the same as the aforementioned three-plate structure, and will not be described again here.

[0083] In other embodiments of this application, the rigid support plate 300 includes a first rigid support plate 310, a second rigid support plate 320, and a third rigid support plate 330. The second rigid support plate 320 and the third rigid support plate 330 are respectively fixedly connected to the left and right sides of the first rigid support plate 310 via flexible connectors, forming a multi-segment foldable plate assembly that can be unfolded as a whole supporting plane and can also be folded for storage. The flexible connectors can be replaced by flexible connectors with similar functions to the aforementioned connecting ropes, flexible connecting substrates, hinges, etc., such as chains, hinges, etc. This type of structure also achieves the connection between the rigid support plates through flexible connectors, which will not be described in detail here.

[0084] In various embodiments of this application, the rigid support plate 300 can be used in conjunction with the vehicle mattress 10 in multiple ways. In one embodiment, the rigid support plate 300 can be placed directly between the mattress body 100 of the vehicle mattress 10 and the vehicle interior structure 200, maintaining its support position through the weight of the mattress body 10 and the pressure of the human body, enabling quick assembly and disassembly and flexible use. In other preferred embodiments, a dedicated receiving structure is provided below the first part 110 of the mattress body 100 to accommodate and fix the rigid support plate 300. This receiving structure can be fixed to the lower surface of the mattress body 100 by high-strength stitching, hot melt bonding, high-frequency welding, or hot-press welding, forming a receiving space that matches the shape of the rigid support plate 300. Through this design, the rigid support plate 300 can be stably placed within the receiving structure, preventing displacement or detachment during use and ensuring that the support area always maintains a corresponding relationship with the first part 110. The accommodating structure can be implemented in various forms, including but not limited to: a bag-like structure formed by three-sided stitching of flexible fabric; a closed accommodating cavity that opens and closes with a zipper; an accommodating bag with an opening secured by Velcro or snaps; and an open accommodating space secured by an elastic cord. Each accommodating structure features an opening design for easy access to the rigid support plate 300, ensuring both ease of use and reliable positioning of the rigid support plate 300 in a vehicle environment. The accommodating structure effectively enhances the overall integrity and ease of use of the vehicle mattress 10 while maintaining the detachable advantage of the rigid support plate 300.

[0085] Figure 14 This is a schematic diagram of another embodiment of the vehicle-mounted mattress of this application. Figure 14As shown, in this embodiment, the vehicle-mounted mattress 10 includes a mattress body 100 and a rigid support plate 300 disposed below it. The mattress body 100 includes a first part 110 and a second part 120, and the rigid support plate 300 corresponds to the first part 110. In this embodiment, the accommodating structure is a storage bag 400 formed by sewing. The storage bag 400 is made of flexible and wear-resistant fabric and includes a storage bag body 410, a first storage bag edge 420, a second storage bag edge 430, and a third storage bag edge (not shown). The edge 420 of the first storage bag is fixedly connected along the boundary line between the first part 110 and the second part 120. The edge 430 of the second storage bag is opposite to the edge 420 of the first storage bag and is fixedly connected along the corresponding side edge of the mattress body 100. The edge of the third storage bag (not shown) is adjacent to the edge 420 of the first storage bag or the edge 430 of the second storage bag and is fixedly connected along the corresponding side edge of the mattress body 100. This forms a bag-shaped accommodating space that is closed on three sides and open on one side. Its size matches the rigid support plate 300, which can stably accommodate and effectively limit the displacement of the rigid support plate 300. The above-mentioned fixed connection methods include, but are not limited to, high-strength sewing, hot melt bonding, high-frequency welding or hot pressure welding, etc., to ensure that the connection is strong and durable and can withstand repeated stress during use. The opening side of the storage bag 400 can be provided with a simple sealing structure, such as Velcro, snaps, drawstrings or zippers, so as to prevent the rigid support plate 300 from accidentally slipping out during vehicle driving or use while being taken out and put in. This implementation method, through an integrated accommodating structure design, maintains the relative positional stability of the rigid support plate 300 and the mattress body 100, while also taking into account the convenience of disassembly and assembly, effectively improving the user experience and reliability of the product.

[0086] Figure 15 This is a schematic diagram of another embodiment of the vehicle-mounted mattress of this application. Figure 15As shown, in this embodiment, the vehicle-mounted mattress 10 includes a mattress body 100 and a rigid support plate 300 disposed below it. The mattress body 100 includes a first part 110 and a second part 120, and the rigid support plate 300 is positioned opposite to the first part 110. The rigid support plate 300 is detachably connected to the underside of the mattress body 100 via a receiving structure. In this embodiment, the receiving structure is a zipper 500, which includes a first zipper strap 510 and a second zipper strap 520. The first zipper strap 510 is disposed below the mattress body 100 and is firmly bonded to the fabric of the mattress body 100, while the second zipper strap 520 is correspondingly disposed on the upper surface edge of the rigid support plate 300. The two are positioned correspondingly to each other and can be matched and connected. In this embodiment, the second zipper tape 520 can be configured as 1, 2, 3, or 4. When configured as 1, it is arranged along the diagonal direction of the upper surface of the rigid support plate 300. When configured as 2, they are respectively disposed on opposite sides of the upper surface of the rigid support plate 300. When configured as 3 or 4, they are respectively disposed on three or four sides of the upper surface of the rigid support plate 300. Of course, it can be understood that the second zipper tape 520 can also be of other quantities or disposed on other sides of the upper surface of the rigid support plate 300. Regarding the location, this application does not impose specific limitations. Accordingly, the first zipper strap 510 is completely matched with the second zipper strap 520 in terms of quantity and arrangement, and is firmly attached to the lower surface of the mattress body 100. When the zipper 500 is closed, the rigid support plate 300 is stably fixed under the mattress body 100, forming an integral structure to ensure that the rigid support plate 300 will not shift or fall off during use. When the zipper 500 is opened, the rigid support plate 300 can be quickly separated from the mattress body 100 for easy individual storage or flexible position adjustment. Preferably, the zipper 500 is a durable zipper with large teeth or a self-locking zipper, which has high tensile strength and durability under repeated opening and closing. The fabric substrate of the zipper 500 is firmly attached to the mattress fabric and the surface of the support plate through high-strength stitching, hot melt bonding, high-frequency welding, hot pressure welding, or adhesive bonding to ensure the reliability of the connection parts. This zipper connection method not only enables the quick assembly and disassembly of the rigid support plate 300, allowing users to flexibly configure it according to their needs, but also allows the mattress body 100 to be separated from the rigid support plate 300 and folded when stored, further reducing the storage volume and improving the convenience of carrying and storing in the limited space of a vehicle.

[0087] Figure 16 This is a schematic diagram of another embodiment of the vehicle-mounted mattress of this application. Figure 16As shown, in this embodiment, the vehicle-mounted mattress 10 includes a mattress body 100 and a rigid support plate 300. The mattress body 100 includes a first part 110 and a second part 120, and the rigid support plate 300 corresponds to the first part 110. The rigid support plate 300 is detachably fixed to the bottom of the mattress body 100 by a rope structure 600. Specifically, the rope structure 600 includes a rope 610 and a rope loop 620. The rope 610 is disposed on the rigid support plate 300, and the rope loop 620 is disposed on the mattress body 100. Through the rope structure 600, the rigid support plate 300 can be detachably fixed to the mattress body 100 for easy use and storage. The rope loop 620 is fixedly disposed on the lower surface or edge area of ​​the mattress body 100, and the rope 610 is correspondingly disposed on the upper surface or side of the rigid support plate 300. A reliable connection between the rigid support plate 300 and the mattress body 100 can be achieved by passing the rope 610 through the rope loop 620 and binding or tightening it. Preferably, the rope 610 can be an elastic braided band or an adjustable rope, equipped with a quick-release buckle, allowing the user to adjust the tightness of the binding according to actual usage needs. The rope loop 620 can be one of a metal D-ring, a plastic adjusting ring, or a fabric ring, and its number and arrangement correspond to the rope 610 to achieve balanced fixation at multiple stress points. In other embodiments, the positions of the rope 610 and the rope loop 620 can be interchanged; that is, the rope 610 can be placed on the mattress body 100, and the rope loop 620 can be placed on the rigid support plate 300. The rope structure 600 not only enables the quick assembly and disassembly of the rigid support plate 300, making it easy for users to separate and store it after use, but also effectively prevents the support plate from shifting or falling off during the inflation or placement of the mattress body 100, ensuring that the support area always corresponds to the first part 110 of the mattress body 100, thus improving the stability of use.

[0088] Figure 17 A structural schematic diagram of another embodiment of the vehicle-mounted mattress of this application is shown. Figure 17As shown, in this embodiment, the vehicle-mounted mattress 10 includes a mattress body 100 and a rigid support plate 300. The mattress body 100 includes a first part 110 and a second part 120, and the rigid support plate 300 corresponds to the first part 110. The rigid support plate 300 is bound and fixed to the bottom of the mattress body 100 by a rope 700. The rope 700 can be made of elastic or non-elastic material, preferably high-strength nylon webbing or polyester rope, which has good abrasion resistance and tensile strength. The user can quickly fix and remove the rigid support plate 300 by adjusting the length or tightness of the rope 700 according to actual needs. In this embodiment, the rope 700 can be set to a cross-binding or parallel wrapping fixing form, which enhances the connection stability between the rigid support plate 300 and the mattress body 100 through multi-point fixing. When the strap 700 is tightened, the rigid support plate 300 is securely bound to the underside of the first part 110 of the mattress body 100, effectively preventing displacement or tilting during use. When disassembly is required, it can be quickly separated simply by loosening the adjustment strap 700, making the operation simple and quick. The fixing structure in this embodiment not only enables the detachable connection of the rigid support plate 300, facilitating flexible adjustment by the user according to the usage scenario, but also allows the mattress body 100 to be folded separately from the rigid support plate 300 during storage, further optimizing storage space and improving portability and storage convenience in a vehicle environment. In various embodiments of this application, the outer contour edges of the rigid support plate 300, especially the corners that come into contact with the vehicle interior, are covered with flexible protective material to prevent scratches to the vehicle interior.

[0089] Figure 18A This is a schematic diagram of another embodiment of the vehicle-mounted mattress of this application. Figure 18B For this application Figure 18A A schematic diagram of the vehicle-mounted mattress in the unfolding process. Figure 18C For this application Figure 18A A diagram illustrating the use of a vehicle-mounted mattress. Figures 18A to 18CAs shown, in this embodiment, the vehicle mattress 10 is suitable for use inside a vehicle. In use, the vehicle mattress 10 is placed on and in contact with the vehicle's interior structure 200. The vehicle interior structure 200 includes vehicle seats and a trunk floor 230. The vehicle seats include front seats 210 and rear seats 220. In this embodiment, the vehicle mattress 10 includes a mattress body 100 and a rigid support plate 300. The mattress body 100 includes a first part 110 and a second part 120. The rigid support plate 300 corresponds to the first part 110 of the mattress body 100, and the second part 120 is integrally connected to the first part 110. The rigid support plate 300 is attached to the lower surface of the mattress body 100. In other embodiments of this embodiment, the rigid support plate 300 may also be embedded inside the mattress body 100. To enable the automatic unfolding function of the car mattress 10, a rotating component 910 is installed on the vehicle seat within the vehicle's interior structure 200, for example, on the rear seat 220 and / or the front seat 210. A through-space is provided below the rotating component 910 for a pull strap 900 to pass through. One end of the pull strap 900 is connected to a motor 920, and the other end, after passing through the through-space between the rotating component 910 and the rear seat 220, is fixed to the lower surface of the first part 110 of the mattress body 100, or to the lower surface of the rigid support plate 300. This allows the pull strap 900 to be wound around the underside of the mattress body 100 and, driven by the motor 920, enables the unfolding and retraction of the car mattress 10. This makes unfolding or retracting the car mattress more convenient, time-saving, and labor-saving for users. Figure 18A As shown, in its stowed state, the car mattress 10 is folded to save space inside the vehicle; Figure 18B and Figure 18CAs shown, when the starter motor 920 drives the pull strap 900 to retract, the pull strap 900 pulls the folded portion of the mattress body 100, causing it to gradually unfold until it is completely laid flat on the vehicle interior structure 200. To obtain more ample resting space, the mattress body 100 of the vehicle mattress 10 extends forward, with its front end extending beyond the top surface of the folded-down rear seat 220 and across the gap area 240 between the rear seat 220 and the front seat 210. The mattress body 100 is made of flexible, airtight material and has air vents. The first part 110 of the mattress body 100, under the corresponding coverage of the rigid support plate 300, spans across the gap area 240 between the rear seat 220 and the front seat 210. The second part 120 may be located above the front seat 210 and / or the rear seat 220 and / or the trunk floor 230. The rigid support plate 300 is made of a lightweight, high-strength material, which can be selected from one or more combinations of honeycomb panels, carbon fiber composites, aluminum alloy profiles, PP plastic sheets, wood panels, or wood plywood. The rigid support plate 300 is positioned below the mattress body 100 and adheres to the lower surface of the mattress body 100, thus giving the mattress body 100 a structurally stable and well-supporting first portion 110. The length of the first portion 110 of the vehicle mattress 10 can be designed according to actual needs, ensuring that a portion of the first portion 110 is located on and supported by the backrest of the rear seat 220 of the vehicle. For example, along a first direction (such as the length direction of the vehicle mattress 10), approximately one-third of the total dimensions of the first portion 110 are located on the backrest of the rear seat 220 and in contact with the top surface of the rear seat 220 backrest, while the remaining two-thirds are suspended, covering the gap area 240 between the rear seat 220 and the front seat 210 of the vehicle. When a user rests using the car mattress 10, a part of the user's body rests on the first part 110, such as the head and shoulders. At this time, the user's shoulders exert pressure on the portion of the first part 110 of the car mattress 10 located on the back of the rear seat 220, and the user's head exerts pressure on the portion of the first part 110 of the mattress body 10 located in the gap area 240 between the rear seat 220 and the front seat 210. Because the first part 110 of the car mattress 10 has good bending resistance and effectively transfers the load to the rear seat 220 through the rigid support plate 300, the first part 110 of the mattress body 100 supporting the user's head will not bend or deform. The user can obtain a relatively flat, stable, and comfortable resting support experience on the first part 110.

[0090] Figure 19A This is a schematic diagram of the mattress body in a retracted state in another embodiment of the vehicle-mounted mattress of this application. Figure 19BThis is a schematic diagram showing the unfolded state of the mattress body in another embodiment of the vehicle-mounted mattress of this application. Figure 19A and Figure 19B As shown, in this embodiment, the vehicle-mounted mattress 10 includes a mattress body 100, wherein the mattress body 100 is filled with a stretchable foam 130, which is formed by a plurality of interconnected geometric foam blocks 1301. Under normal conditions without any external force, the geometric foam blocks 1301 in the stretchable foam 130 are tightly bonded together by the elasticity of the material and the toughness of the connecting parts, forming a dense whole without internal gaps. When a tensile force is applied along the plane of the mattress body 100, the geometric foam blocks 1301 in the stretchable foam 130 undergo relative displacement, thereby unfolding the mattress and forming gaps between adjacent geometric foam blocks 1301 to increase the support area, and the stretchable foam 130 can be stretched into a stretched shape. After the applied external force is removed, the stretchable foam 130 can maintain its stretched shape by its own maintenance characteristics. When a compressive force is applied to the stretchable foam 130 in the stretched shape along the plane of the mattress body 100, the stretchable foam 130 can be compressed into a compact shape. This internally filled stretchable foam 130 structural design allows the mattress body 100 to be greatly compressed in volume during storage, significantly improving storage convenience and reducing space occupation. Simultaneously, the mattress body 100 also possesses greater deformability, allowing for more flexible storage methods. It is understood that the solution of filling the mattress body 100 with stretchable foam 130 in this embodiment can be applied to the structure of the mattress body 10 in the above-described embodiments.

[0091] Furthermore, in all the above embodiments, the bottom and / or sides of the rigid support plate 300 may be provided with an anti-slip structure. The anti-slip structure may be one of a high-friction coefficient silicone pad, a retractable support claw, or a rough textured surface, which effectively prevents the rigid support plate 300 from shifting during use and improves the stability of the vehicle mattress during use.

[0092] Furthermore, the mattress body 100 in this application is an inflatable mattress body. This application may also include an air pump that is stored in conjunction with it. The air pump is connected to the air inlet of the mattress body 100 through a detachable pipe, so that the user can easily inflate and deflate the mattress body 100.

[0093] Furthermore, the upper surface of the mattress body 100 may be laminated with a soft layer, such as a fleece layer, a slow-rebound foam layer, or a gel particle layer, to enhance comfort. The rigid support plate 300 is made of lightweight, high-strength materials, such as honeycomb panels, carbon fiber composites, aluminum alloy profiles, PP plastic boards, or wood plywood, ensuring both support performance and portability.
