[0033] Reference Figures 1 to 4 :

[0034] This application first provides an embodiment of a folding bed structure at the front end of a house car, which comprises:

[0035] bed frame assembly 01, fixed support 02, front support connecting rod 03, rear support connecting rod 04, transmission connecting rod 05 and damping member 06;

[0036] The two ends of the front support connecting rod 03 and the rear support connecting rod 04 are rotatably connected with the bed frame assembly 01 and the fixed support 02 respectively, the transmission connecting rod 05 is rotatably connected with the fixed support 02, and is connected with the front support connecting rod 03 and / or the rear support connecting rod 04, one end of the damping member 06 is rotatably connected with the fixed support 02, and the other end is rotatably connected with the transmission connecting rod. When the bed frame assembly is unfolded or folded relative to the fixed support 02, the front support connecting rod 03 and / or the rear support connecting rod 04 drives the transmission connecting rod 05 to rotate, thereby compressing or stretching the damping member 06.

[0037] The embodiment of the folding bed structure at the front end of the motor home realizes smooth operation and reliable support of the folding bed through the coordination of multiple components. The following is a detailed description of each component in the structure and its working principle:

[0038] Bed frame assembly 01: As the core part of the folding bed, it is used to bear the weight of the user and provide a sleeping surface. The bed frame assembly 01 is connected to other components through a rotating connection, which can switch between folding and unfolding. It can be made of lightweight but strong materials such as aluminum alloy or high-strength steel, ensuring that it can bear the load without adding too much weight.

[0039] Fixed support 02: The fixed support 02 provides a stable fixed base for the entire folding bed structure. It can be fixed to the front end of the motor home body, and through the connection with the support link and transmission link 05, it ensures the stability and overall rigidity of the folding bed during operation.

[0040] Front support link 03 and rear support link 04: These two support links constitute the main support structure of the folding bed, connecting the bed frame assembly 01 and the fixed support 02, and providing support force when unfolded.

[0041] Both ends can be connected to the bed frame assembly 01 and the fixed support 02 through a hinged connection, which can rotate freely.

[0042] During folding and unfolding, the rotation trajectory of the support link determines the position and angle of the bed body. The front support link 03 and the rear support link 04 can work together to disperse and balance the weight of the bed body, preventing structural instability caused by single-point force.

[0043] Transmission link 05: As the core of connection and driving, it coordinates the linkage of the front support link 03, the rear support link 04, and the damping member 06. One end is connected to the fixed support 02 through a rotating connection. The other end is connected to the front support link 03 and / or the rear support link 04, thereby driving the movement of the bed body when it is unfolded or folded. The transmission link 05 can transmit the movement of the support link to the damping member 06, forming force conversion and buffering, ensuring smooth and smooth operation throughout the process.

[0044] Damping member 06:

[0045] Provides buffering and energy absorption functions, reducing the impact force generated during folding or unfolding, protecting the structure and improving the operation experience. One end is connected to the fixed support 02 through a rotating connection. The other end is connected to the transmission link 05, and is compressed or stretched with the rotation of the transmission link 05.

[0046] The damping member 06 is gradually compressed when the bed body is unfolded, absorbing the kinetic energy of the bed body, thereby preventing the impact caused by too fast unfolding. When folding, the damping member 06 gradually releases energy, assisting the movement of the support link, making the folding action more stable. The damping member 06 can adopt a gas pressure or spring damping structure, which is reliable and easy to maintain.

[0047] In the structure provided by this embodiment, when the bed body needs to be unfolded, the user pushes or pulls the bed frame assembly 01, the front support link 03 and the rear support link 04 start to rotate, the transmission link member 05 is driven to rotate, and the damping member 06 is compressed. At this time, the damping member 06 absorbs part of the impact force generated during the unfolding process, ensuring that the unfolding action is smooth and smooth. Finally, the front support link 03 and the rear support link 04 support the bed frame assembly 01, completing the unfolding.

[0048] When the bed body needs to be folded, the user pushes the bed frame assembly 01 to rotate towards the fixed support 02, the front support link 03 and the rear support link 04 start to rotate in the opposite direction, the transmission link member 05 also moves, driving the damping member 06 to stretch. The damping member 06 provides auxiliary force during stretching, reducing the user's operating burden, while preventing the folding speed from being too fast to damage the structure.

[0049] In an optional embodiment, the damping member can be selected to use a conventional gas spring or a lockable gas spring according to specific needs. If a lockable gas spring is selected, an unlocking pull wire needs to be designed and installed at the front end of the bed frame assembly to achieve unlocking control of the gas spring.

[0050] When a conventional gas spring is used, its main function is to provide cushioning and assistance, making the bed body more stable during folding or unfolding, reducing sudden impact or shaking, and improving user operation comfort.

[0051] The lockable gas spring has a locking function and can fix the bed body at any position, which helps to meet the flexible adjustment needs of the bed body position in the RV use scenario. It can lock the bed body at any position to adapt to more use needs.

[0052] When a lockable gas spring is selected, the unlocking pull wire is a key control component, and its main function is to allow the user to unlock the gas spring through simple pull wire operation, thereby adjusting the position of the bed body.

[0053] The unlocking pull wire can be fixed at the front end of the bed frame assembly for easy user operation, and the length and arrangement of the pull wire need to consider the movement range of the folding bed to ensure smooth operation without obstruction.

[0054] One end of the unlocking pull wire is connected to the unlocking device of the gas spring, and the other end extends to a position easily accessible by the user.

[0055] A pull cable sleeve can be used to protect the pull cable from being damaged during folding or unfolding.

[0056] When the user adjusts the bed body, the user can release the locking function of the gas spring by pulling the unlocking pull cable. At this time, the gas spring provides a buffer or assistance, and the user can smoothly adjust the position of the bed body.

[0057] After adjustment, the unlocking pull cable is released, and the gas spring is automatically locked to fix the position of the bed body.

[0058] In an optional embodiment, the transmission link member 05 includes a front rotating rod 07, a rear rotating rod 08, and a connecting rod 09. The front rotating rod 07 is connected to the fixed support 02 through a same rotation point with the front support link, the rear rotating rod 08 is connected to the fixed support 02 through a same rotation point with the rear support link, and the two ends of the connecting rod 09 are rotatably connected with the front rotating rod 07 and the rear rotating rod 08, respectively.

[0059] In this optional embodiment, the structure of the transmission link member 05 is refined and optimized, and the front rotating rod 07, the rear rotating rod 08, and the connecting rod 09 are added, so that the transmission link member 05 can provide more efficient linkage and force transmission during the unfolding and folding of the folding bed.

[0060] In this embodiment, the front rotating rod 07, as a key component in the transmission system, is connected with the front support link and the fixed support 02 to realize force transfer and angle adjustment. One end of the front rotating rod 07 is connected with the fixed support 02 through a rotation point to form a rotation shaft. The other end of the front rotating rod 07 is connected with the front support link through the same rotation point to realize synchronous movement of the two.

[0061] When the bed body is unfolded, the front rotating rod 07 rotates with the movement of the front support link to transfer the movement track of the front support link to the connecting rod 09. When the bed body is folded, the front rotating rod 07 reversely rotates to coordinate the linkage of other components through the connecting rod 09.

[0062] The rear rotating rod 08 is connected with the rear support link and the fixed support 02 to provide a movement fulcrum for the rear support link and work cooperatively with the front rotating rod 07 to realize overall transmission. One end of the rear rotating rod 08 is connected with the fixed support 02 through a rotation point, which is independent of the position of the front rotating rod 07 but similar in structure. The other end of the rear rotating rod 08 is connected with the rear support link through the same rotation point to form a stable movement linkage.

[0063] During unfolding, the rear rotating rod 08 rotates with the rear support link to convert the movement of the rear support link into coordinated movement of the transmission link. During folding, the rear rotating rod 08 reversely rotates to provide uniform support force for the bed body.

[0064] The connecting rod 09 serves as a connecting element between the front rotating rod 07 and the rear rotating rod 08, ensuring the synchronization of their movements, thereby coordinating the linkage of the front support link and the rear support link. The two ends are respectively connected to the front rotating rod 07 and the rear rotating rod 08 through hinges or rotating shafts, which can rotate freely to adapt to the relative movement of the two. The connecting rod 09 can transmit force and motion between the front rotating rod 07 and the rear rotating rod 08, realizing the coordinated unfolding and folding of the support link.

[0065] Through precise length design and connection position, the connecting rod 09 can effectively control the angle and speed of the bed body unfolding or folding, and improve the structural stability.

[0066] The working principle of the overall linkage structure is as follows:

[0067] When the bed body is unfolded, the user pushes the bed frame assembly 01 to unfold, and the front support link and the rear support link begin to rotate. The movement of the front support link drives the front rotating rod 07 to rotate, and the movement is transmitted to the rear rotating rod 08 through the connecting rod 09. The rear rotating rod 08 rotates accordingly, driving the rear support link to unfold, while coordinating the buffering function of the damping member 06, ensuring the smooth unfolding action. The entire transmission system distributes the force to each support point through the linkage of the front rotating rod 07, the rear rotating rod 08 and the connecting rod 09, forming uniform and stable support.

[0068] When the bed body is folded, the user pushes the bed frame assembly 01 to fold, and the rear support link and the front support link begin to rotate in reverse. The movement of the rear support link drives the rear rotating rod 08 to rotate in reverse, and the movement is transmitted to the front rotating rod 07 through the connecting rod 09. The front rotating rod 07 rotates in reverse accordingly, driving the front support link to fold, while coordinating the buffering effect of the damping member 06 to prevent the folding speed from being too fast. The transmission system remains coordinated to ensure uniform distribution of force during the folding process, avoiding structural damage.

[0069] In an optional embodiment, one end of the damping member 06 is rotatably connected to the fixed support 02, and the other end is rotatably connected to the front rotating rod 07.

[0070] In this optional embodiment, the structure and connection method of the damping member 06 are optimized. By connecting one end of the damping member 06 to the fixed support 02 and the other end to the front rotating rod 07, the buffering effect and motion smoothness of the entire folding bed structure during unfolding and folding are further improved. One end is connected to the fixed support 02: one end of the damping member 06 is rotatably connected to the fixed support 02 through hinges or rotating shafts, allowing the damping member 06 to adjust its direction with the movement of the bed body. This connection method ensures that the damping member 06 remains flexible when under stress, while providing a stable fulcrum to bear part of the force generated during transmission. The other end of the damping member 06 is rotatably connected to the front rotating rod 07 through a similar hinge or rotating shaft.

[0071] Through this connection, the damping member 06 can directly respond to the motion state of the front rotating rod 07, providing damping effect when the folding bed is unfolded or folded.

[0072] This embodiment is suitable for folding bed structures that need to be frequently adjusted in a motor home, especially in scenarios where safety and user comfort are desired. It is particularly suitable for use on bumpy or uneven roads, effectively preventing structural loss of control due to excessive movement during bed unfolding or folding.

[0073] In an optional embodiment, the front support link 03 and the rear support link 04 are arranged on the side of the bed frame assembly 01, and the front support link 03 and the rear support link 04 are provided with a bending part 10. The lower part of the bending part 10 of the front support link 03 or the rear support link 04 is closer to the bed frame assembly 01 than the upper part.

[0074] In this optional embodiment, the design of the front support link 03 and the rear support link 04 optimizes the overall structural arrangement and motion path by adding the bending part 10, while improving the stability of the folding bed during unfolding and folding.

[0075] The front support link 03 and the rear support link 04 are arranged along the side of the bed frame assembly 01, i.e. parallel to the side edge of the bed frame assembly 01. This arrangement effectively reduces the occupation of the space below the bed frame assembly 01, allowing the space below the bed to be used for storage or other purposes, optimizing the utilization of the interior space of the motor home.

[0076] The front support link 03 and the rear support link 04 are both designed with a bending part 10, which can be located in the middle of the link or near the connection part. The lower part of the bending part 10 (the end closer to the bed frame assembly 01) is closer to the bed frame assembly 01 than the upper part, forming an inwardly curved shape.

[0077] The angle of the bending part 10 is designed according to the unfolding and folding needs of the bed, which can be an acute angle or a right angle. The bending direction is parallel to the side of the bed frame assembly 01, avoiding interference with the motion of other components.

[0078] In this embodiment, the design of the bending part 10 allows the link to avoid the side or the structure below the bed frame assembly 01 during unfolding and folding, avoiding collision or interference during motion.

[0079] The presence of the bending part 10 also adjusts the force direction of the link, making the support force more stable and evenly distributed. When the bed is unfolded, the lower part of the bending part 10 is closer to the bed frame assembly 01, effectively lowering the center of gravity of the link, enhancing the support stability of the bed, and reducing the possibility of shaking or tilting.

[0080] The bending design can also increase the distance between the connecting point of the connecting rod and the bed frame assembly 01, further dispersing the stress on the bed body and prolonging the service life of the assembly. The design of the bending part 10 close to the bed frame assembly 01 makes the connecting rod close to the bed frame assembly 01 in the folded state, occupying less space and providing more flexibility for the interior layout of the motor home.

[0081] In an optional embodiment, the bed frame assembly 01 includes an outer frame 11, a middle beam 12 fixed to the outer frame 11 and located in the middle of the outer frame 11, and a rib 13 fixed between the middle beam 12 and the outer frame 11.

[0082] In this optional embodiment, the structure design of the outer frame 11, the middle beam 12 and the rib 13 improves the overall rigidity and carrying capacity of the bed frame assembly 01, while optimizing the weight and space utilization of the bed frame.

[0083] The outer frame 11 constitutes the peripheral frame of the bed frame assembly 01, providing basic shape and size constraints. High-strength lightweight materials such as aluminum alloy, steel or composite materials can be used to ensure that the overall structure is stable and lightweight. The outer frame 11 provides support for the middle beam 12 and the rib 13, and serves as the connection point between the bed body and the fixed support 02 and the supporting connecting rod.

[0084] The middle beam 12 is fixed to the outer frame 11 and located in the middle of the outer frame 11, extending through the entire length or width direction of the bed frame assembly 01. The middle beam 12 serves to distribute the load of the bed body, evenly transmitting the force from the bed body surface to the outer frame 11; at the same time, the middle beam 12 provides an installation fulcrum for the rib 13. The middle beam 12 can be made of high-rigidity material and can be connected to the outer frame 11 by welding, riveting or bolting.

[0085] The rib 13 is installed between the middle beam 12 and the outer frame 11 and can be distributed in parallel at a certain distance, forming a grid-like structure support. The rib 13 further refines the stress distribution of the bed frame, preventing deformation caused by excessive load in local areas; at the same time, the rib 13 improves the bending and torsional resistance of the bed frame. The cross-sectional shape of the rib 13 can be designed as rectangular, L-shaped or hollow structure according to needs, taking into account strength and weight.

[0086] In this embodiment, the design of the middle beams 12 and the ribs 13 evenly distributes the load on the bed surface to the outer frame 11, avoiding local deformation or damage caused by concentrated load. The layout of the central axis of the middle beams 12 effectively improves the longitudinal rigidity of the bed frame, while the ribs 13 enhance the lateral support force. By reasonably arranging the middle beams 12 and the ribs 13, the amount of material used can be reduced while maintaining sufficient strength, thereby reducing the overall weight of the bed frame assembly 01 and improving the overall energy efficiency of the motor home. The firm connection between the ribs 13 and the middle beams 12, the outer frame 11 makes the bed frame assembly 01 less likely to loosen or deform during long-term use. This design is particularly suitable for the vibration environment during the driving of the motor home, and can effectively absorb and disperse external impact forces.

[0087] In an optional embodiment, the outer frame 11 is fixedly provided with a baffle 14.

[0088] In this optional embodiment, the outer frame 11 is fixedly provided with a baffle 14, which is fixed to the outer frame 11 of the bed frame. The main purpose is to provide support for the mattress after the bed body is unfolded. The design of the baffle 14 can effectively prevent the mattress from sliding or shifting during use, ensuring that the mattress always remains on the bed frame assembly 01 and enhancing the stability of the mattress. When the bed frame is unfolded and the mattress is placed, the baffle 14 can serve as an edge support for the mattress, preventing it from sliding out of the bed frame due to user activity or bed body shaking. The arrangement of the baffle 14 around the mattress ensures that the mattress always maintains close contact with the bed frame, avoiding unstable or uncomfortable use experience.

[0089] When the bed frame is unfolded, the baffle 14 provides a clear position for the mattress, allowing the user to easily place the mattress on the bed frame, ensuring that the mattress does not deviate from the bed frame. The presence of the baffle 14 also facilitates the replacement and cleaning of the mattress, as the mattress will not move under the constraint of the baffle 14.

[0090] In an optional embodiment, the front support link 03 and the rear support link 04 are arranged in parallel.

[0091] In an optional embodiment, the front support link 03 and the rear support link 04 are arranged in parallel, which helps to achieve symmetry and balance in the bed frame structure. When the bed body is unfolded or folded, due to the parallel configuration of the front and rear support links 04, the two support points provide uniform force transmission, avoiding the problem of bed frame tilting or shaking caused by uneven force. Therefore, this design can improve the stability of the bed frame during use, especially when the bed body is fully unfolded, enhancing the support force and comfort of the mattress.

[0092] In an optional embodiment, the fixing support 02 comprises a side plate 15 and a bottom plate 16, the bottom plate 16 is fixed to the bottom of the side plate 15 and is perpendicular to the side plate 15, the side plate 15 is provided with a plurality of triangular hollow parts 150 and a plurality of fixing holes 151 for fixing, and the bottom plate 16 is provided with a fixing pile head 161, and the fixing pile head is provided with a screw hole 160.

[0093] In an optional embodiment, the fixing support 02 comprises a side plate 15 and a bottom plate 16, which can significantly enhance the stability and convenience of the folding bed structure at the front end of the motor home.

[0094] The configuration of the side plate 15 and the bottom plate 16 forms a stable support structure. The bottom plate 16 is fixed to the bottom of the side plate 15 and is perpendicular to the side plate 15. In this way, the vertical relationship between the bottom plate 16 and the side plate 15 enhances the stability of the support, so that the fixing support 02 can withstand more force during use and effectively avoid shaking or displacement of the bed body when subjected to external force. The provision of the side plate 15 can provide lateral support for the overall bed frame, ensuring that the bed frame is more stable when unfolded or folded.

[0095] The side plate 15 is provided with a plurality of triangular hollow parts 150, and the design of the triangular hollow parts 150 has the following effects:

[0096] Through the hollow design, unnecessary material use can be reduced, thereby reducing the overall weight, which is helpful for optimizing the interior space of the motor home and making the movement of the bed body more convenient.

[0097] The side plate 15 is provided with a plurality of fixing holes 151 for fixing, and these fixing holes are used to facilitate the firm connection of the bed frame assembly 01 and the fixing support 02, ensuring that the bed frame will not loosen or displace during use due to external force.

[0098] The fixing pile head on the bottom plate 16 is designed to ensure that the bed frame can be stably fixed on some supports, and the fixing pile head on the bottom plate 16 is provided with a screw hole, which can be connected with the screw on the bed frame assembly 01, thereby enhancing the connection strength between the bed frame assembly 01 and the support, and improving the overall stability and load-bearing capacity of the bed frame structure.

[0099] The fixing holes on the side plate 15 and the fixing pile head on the bottom plate 16 provide the function of convenient disassembly and installation. Through the cooperation of bolts or screws, users can quickly install and disassemble the bed frame assembly 01, which is convenient for maintenance and adjustment. This structural design simplifies the installation process of the bed frame, saves time and effort, and improves the convenience of use.

[0100] In an optional embodiment, the fixing support 02 further comprises a top plate 17, which is fixed to the top of the side plate 15 and is perpendicular to the side plate 15.

[0101] In an optional embodiment, the side plate 15, the bottom plate 16 and the top plate 17 are integrally formed.

[0102] The vertical fixation of the top plate 17 and the side plate 15 can further increase the overall stability and strength of the fixed support 02, especially during the support process of the bed frame assembly 01. Through the vertical connection of the top plate 17 and the side plate 15, the top plate 17 not only can provide additional support force, but also can ensure the rigidity of the entire support structure, making the bed body more stable during unfolding or folding. The provision of the top plate 17 helps the structural integrity of the bed frame structure, effectively reducing the possibility of deformation during use, thereby improving the service life and durability of the bed frame.

[0103] In an optional embodiment, the side plate 15, the bottom plate 16 and the top plate 17 are integrally formed, which means that these components do not need to be manufactured and assembled separately, which can simplify the manufacturing process and reduce production costs. By using a mold for integral molding, not only the production efficiency is improved, but also the accuracy and consistency of each support component are ensured. The integrally formed structure can be more evenly distributed when stressed compared to separately connected components. Whether it is the mechanical action during the unfolding or folding of the bed frame, or the pressure when the bed frame is bearing, the integrally formed structure can effectively resist deformation and stress concentration, enhancing the overall stability of the support.

[0104] Referring to Figure 4 In an optional embodiment, the bed frame assembly is provided with a limiting piece 18, which is used to limit the folding angle of the bed frame assembly.

[0105] The main function of the limiting piece 18 is to limit the maximum folding angle of the bed frame assembly. When the bed body reaches the predetermined angle during folding or unfolding, the limiting piece 18 plays a role in preventing further folding or unfolding. This design can effectively avoid damage to the bed frame assembly due to excessive folding, thereby prolonging the service life of the bed frame.

[0106] By setting the limiting position of the limiting piece 18, the user can adjust the height of the bed body in the folded state. This adjustment function can optimize the storage position of the bed body according to the specific needs of the interior space of the motor home, ensuring efficient use of space.

[0107] The limiting piece 18 also has a certain buffering function, which can slow down the movement speed of the bed body when it is folded or unfolded to the limit position, reducing the impact force caused by sudden stopping. This buffering effect not only protects the bed frame structure and related components, but also improves the safety and comfort of user operation.

[0108] The limiting piece 18 can adopt a mechanical limiting form, such as a stop block or a limiting rod. This form is simple and reliable, and can effectively limit the angle of the bed frame through physical contact.

[0109] If it is desired to enhance the buffering effect, the limiting piece 18 can use an elastic material (such as a rubber pad or a spring) to provide flexible buffering when the bed body contacts the limiting piece, thereby further reducing the impact force.

[0110] To meet the needs of different recreational vehicle layouts, the limiting piece 18 can be designed in an adjustable form. For example, through a knob or a sliding rail, the user can manually adjust the position of the limiting piece, flexibly controlling the folding angle and storage height of the bed body.

[0111] It should be noted that the above description of the disclosed embodiments enables a person skilled in the art to implement or use the present application. Various modifications to these embodiments will be apparent to those skilled in the art, and the general principles defined herein can be implemented in other embodiments without departing from the scope of the present application. Therefore, the present application is not limited to the embodiments shown herein, but is intended to conform to the broadest scope consistent with the principles and novel features disclosed herein.
