Description

Technical Field

[0001] The present application relates to the technical field of RV accessories, and particularly to a flip bed structure and an RV. Background Art

[0002] Currently, an RV is a special vehicle that integrates a means of transportation and a living space. Essentially, it is a "home on wheels". It integrates the cockpit and the living area through the body design to achieve the dual functions of mobility and residence.

[0003] There is a type of light RV on the market with a narrow internal space, and it is impossible to install a fixed bed inside. Therefore, there is a double-flip bed design structure. For related technologies, refer to Figure 1 , the double-flip RV includes a box body 710, two split top covers 720 rotatably mounted on the box body 710, and an assisting structure 730 provided on the box body 710; the assisting structure 730 generally uses a gas spring. One end of the gas spring is rotatably connected to the box body 710, and the other end is rotatably connected to the split top cover 720. When in use, the two split top covers 720 are rotated out by the assistance of the assisting structure 730 to serve as a bed for living; however, there is a docking seam at the splicing position in the middle of the split structure. The existence of the docking seam is not beautiful, and it is difficult to seal and prone to water leakage; to solve the sealing problem, the method of overlapping the two top covers can be adopted to eliminate the docking seam. However, with the setting of overlapping the two top covers, the lower top cover cannot adopt the existing gas spring installation method for assistance and buffering. Generally, the top cover is relatively heavy, and it is difficult to open and close the top cover manually without the assistance of the gas spring; on the other hand, due to the limitation of the width of the RV itself, after the two split top covers on both sides are opened, the two formed beds are relatively narrow, resulting in limited use scenarios. Summary of the Invention

[0004] The present application provides a flip bed structure and an RV, which can at least partially solve the above technical problems.

[0005] In a first aspect, a flip bed structure provided by the present application adopts the following technical solution: A flip bed structure includes a flip bed and a flipping mechanism. The flipping mechanism includes a flip plate and a connecting shaft. The flip plate is L-shaped. One end of the flip plate is connected to the connecting shaft, and the other end of the flip plate is connected to the flip bed; the connecting shaft is rotatably arranged on the RV body. When the flip bed is in the storage state, it can be completely located within the accommodation space of the RV body.

[0006] By adopting the above technical solution, the flipping bed rotates outward around the connecting shaft through the flipping plate, flipping from the accommodation space of the RV to the external horizontal position to form the use state; the flipping bed rotates reversely through the flipping plate and enters the accommodation space of the RV; through the rotation path design of the L-shaped flipping plate, the bed body can be completely placed inside the RV, realizing embedded storage, eliminating external protrusions, optimizing space utilization, and making the RV more beautiful; when in use, the size of the flipping bed is close to the accommodation space of the RV body, providing a larger bed body, improving the comfort of living, being applicable to more usage scenarios, reducing the limitation on usage scenarios; moreover, the combination of the L-shaped flipping plate and the connecting shaft replaces the complex connecting rod system, reducing the manufacturing cost.

[0007] Optionally, it further includes an assisting mechanism. The assisting mechanism includes a connecting rod and an assisting component. One end of the connecting rod is fixedly connected to the connecting shaft, the other end of the connecting rod is rotatably connected to one end of the assisting component, and the other end of the assisting component is rotatably arranged on the RV body.

[0008] Due to the interference of the structure, the gas spring structure adopted in the prior art cannot be installed on the flipping bed inside the RV body in this solution. By adopting the above technical solution, when the flipping bed flips outward, the assisting component releases elastic potential energy and transmits thrust through the connecting rod, reducing the manual operation intensity; when the flipping bed flips inward, the gas spring provides damping buffering to avoid damage to the structure caused by the rapid fall of the bed body; it provides thrust in the unfolding stage and resistance in the recovery stage to achieve two-way assistance; the buffering function reduces the risk of the bed body hitting and improves the use safety; preferably, the assisting component is a gas spring.

[0009] By adopting the above technical solution, the gas spring is a mature component with high reliability and easy maintenance; through the compression and release of the gas spring, the assisting and damping effects are precisely adjusted to achieve the assistance for the flipping of the flipping bed.

[0010] Optionally, a supporting mechanism is arranged on the flipping bed, and the supporting mechanism is used to support the flipping bed that is flipped open.

[0011] By adopting the above technical solution, the supporting mechanism supports on the ground, enhancing the stability of the bed body; the supporting mechanism prevents the bed body from shaking and ensures the use safety.

[0012] Optionally, the supporting mechanism includes a support rod, and the support rod is hinged to the flipping bed and can be folded or rotated around the hinge point.

[0013] By adopting the above technical solution, the support rod can be folded and attached to the bottom of the bed body, reducing space occupation. The folding design avoids the exposure of the supporting components and keeps the appearance of the RV clean. The support rod rotates through the hinge point, and the operation is simple.

[0014] Optionally, a top cover is provided on the RV body, and the top cover is used to open or close the accommodation space of the RV body.

[0015] By adopting the above technical solution, the setting of the top cover can close the accommodation space of the RV body, and the top cover is integrally formed without butt joints, avoiding the problem of water seepage at the joints of the traditional split top cover and improving the sealing effect.

[0016] Optionally, after the top cover is opened, it can be used as a bed body, and at this time, the top cover and the folding bed are respectively located at both ends of the RV body.

[0017] By adopting the above technical solution, the top cover has the dual functions of closing and expanding the bed body, improving the space utilization rate. The RV can provide both an internal bed body and a top cover bed body at the same time, increasing the living space and meeting the usage needs of multiple people; the top cover is integrally formed without butt joints, avoiding the problem of water seepage at the joints of the traditional split top cover and improving the sealing effect; and by being arranged at both ends of the RV body, the stress of the RV body is balanced.

[0018] Preferably, the top cover is rotatably arranged on the RV body and is equipped with a power-assisted gas spring.

[0019] In a second aspect, a kind of RV provided by the present application adopts the following technical solution: An RV includes a folding bed structure.

[0020] By adopting the above technical solution, through the embedded storage of the folding bed structure, more activity space is released, enhancing the living experience.

[0021] To sum up, the present application includes at least one of the following beneficial technical effects: 1. When the folding bed is partially retracted, it is located inside the accommodation space of the RV body, and when the top cover is retracted, it is located above the folding bed, forming an overall wrapped structure, eliminating the middle joint, having strong sealing performance and more beautiful appearance.

[0022] 2. The gas spring and the connecting rod structure enable the gas spring to achieve the effect of labor-saving upward flipping and buffering downward flipping both in the unfolding stage and the retracting stage of the bed body.

[0023] 3. After being flipped and opened, the sizes of the bed body and the top cover are doubled compared with the previous double-flipping structure, and two large beds can be provided. BRIEF DESCRIPTION OF THE DRAWINGS

Detailed implementation manners

[0026] The following is Figures 2 to 11 a further detailed description of the present application.

[0027] This embodiment discloses an RV, which includes a flipping bed structure.

[0028] Refer to Figures 2 to 5, a recreational vehicle, mainly includes a top cover 200, a folding bed 300, a folding mechanism 400, an assisting mechanism 500 and a recreational vehicle body 100. The recreational vehicle body 100 is a trailer structure with wheels and temporary parking supports, and its main body is in a box structure, which is provided with a receiving space 110; the top cover 200 is movably arranged on the recreational vehicle body 100 for closing or opening the receiving space 110; the folding bed 300 is foldably connected to the recreational vehicle body 100 through the folding mechanism 400 and the assisting mechanism 500, so that the folding bed 300 has three position states: the first position a1: the folding bed 300 is horizontally unfolded and used as a bed; the second position a2: the folding bed 300 is vertical; the third position a3: the folding bed 300 is completely received into the receiving space 110; when the folding bed 300 is completely received into the receiving space 110, the top cover 200 closes the receiving space 110 to reduce rainwater or other dust impurities from entering the receiving space 110.

[0029] Refer to Figure 6 , the folding bed 300 includes a bed board 310 and corner boards 320. The bed board 310 is a rectangular board with edges wrapped to protect the edges of the bed board 310, and the corner boards 320 are fixedly connected to both ends of the short side of the bed board 310.

[0030] Refer to Figure 7 , Figure 8 and Figure 9, the flipping mechanism 400 includes a flipping plate 410, a connecting shaft 420, and a mounting assembly 430. The mounting assembly 430 includes a mounting plate 431, a rotating bushing 432, a connecting bushing 433, and a mounting pressure plate 434. The mounting plate 431 is a rectangular plate that fits against the outer wall of the RV body 100 and is close to the top cover 200. First mounting holes 435 and second mounting holes 436 are formed in the mounting plate 431. Both the first mounting holes 435 and the second mounting holes 436 are composed of several through holes and are symmetrically arranged at both ends of the short side of the mounting plate 431. The rotating bushing 432 is fixedly connected to one end of the mounting plate 431 where the first mounting holes 435 are formed. The connecting bushing 433 is fixedly connected to one end of the mounting plate 431 where the second mounting holes 436 are formed. The mounting pressure plate 434 fits against the inner wall of the accommodation space 110 of the RV body 100. The mounting pressure plate 434 includes a large pressure plate and two small pressure plates, which have the same function. The large pressure plate corresponds to one end of the mounting plate 431 where the first mounting holes 435 are formed. Threaded third mounting holes 437 corresponding to the first mounting holes 435 and the second mounting holes 436 are formed in both the large pressure plate and the small pressure plates. During installation, first, pre-position the mounting plate 431 on the outer wall of the RV through the first mounting holes 435 and the second mounting holes 436. Insert bolts into the first mounting holes 435 and the second mounting holes 436, and then assemble the large pressure plate and the small pressure plates from the inside, so that the bolts are threadedly connected to the third mounting holes 437 on the pressure plates. Tighten the bolts to complete the fastening, thereby clamping and fixing on the RV side wall. The flipping plate 410 is rotatably connected to the rotating bushing 432 through the connecting shaft 420. In this way, the side wall of the RV is clamped between the mounting plate 431 and the mounting pressure plate 434, and finally, by tightening the bolts, a basis for the stable installation of the flipping plate 410 is provided.

[0031] The flipping plate 410 includes side plates 411, a connecting plate 412, and a crankshaft bushing 413. The side plates 411 are a pair of L-shaped plates. The flipping plate 410 is connected to the gusset plate 320 on the bed plate 310 through the bottom connecting plate 412. Connecting plates 412 are also provided on the upper and rear parts of the side plates 411, which play a role in strengthening the overall structure of the flipping plate 410. Fourth mounting holes are formed at the bottoms of the two side plates 411. The crankshaft bushing 413 passes through the fourth mounting holes on both sides and is arranged between the two side plates 411. The connecting shaft 420 is inserted into the rotating bushing 432 and is rotatably connected to the rotating bushing 432. The crankshaft bushing 413 is fixedly connected to one end of the side plate 411 away from the bed plate 310, that is, the end where the short side of the L-shaped plate is away from the long side. The connecting shaft 420 is inserted into the crankshaft bushing 413 and remains relatively fixed to the crankshaft bushing 413, driving the crankshaft bushing 413 to rotate together. And the connecting shaft 420 passes through the rotating bushing 432 and is rotatably connected to the rotating bushing 432.

[0032] A power assist mechanism 500 is provided outside the RV body 100. The power assist mechanism 500 includes a power assist component 520, a connecting rod 510, and a connecting rod shaft 530. The power assist component 520 can be structures such as a hydraulic damper, an electric push rod, a magnetic power assist device, a gas spring, etc. In this embodiment, the power assist component 520 is preferably a gas spring, which includes a cylinder 521, a piston rod 522, and a ball head bolt 523. The ball head bolt 523 is provided at the outer ends of the cylinder 521 and the piston rod 522. One end of the connecting rod 510 is provided with a shaft hole 512, and the other end is provided with a bolt hole 511. The ball head bolt 523 provided at one end of the cylinder 521 is rotatably connected to the connecting shaft sleeve 433 on the mounting plate 431. The ball head bolt 523 provided at one end of the piston rod 522 is rotatably connected to the connecting rod 510 through the bolt hole 511. The connecting rod shaft 530 passes through the shaft hole 512 and is fixedly connected to the connecting rod 510, and the connecting rod shaft 530 is coaxial and integrally formed with the connecting shaft 420. The connecting rod 510 is rotatably connected through the connecting rod shaft 530 and the rotating shaft sleeve 432. When the power assist component 520 is in a compressed state, it can store elastic potential energy.

[0033] Through the arrangement of the connecting rod 510 and the connecting rod shaft 530, the installation of the power assist component 520 is realized, enabling the flip bed 300 to be completely flipped into the accommodation space 110, achieving the functions of labor-saving ascent and falling buffer.

[0034] The connecting rod shaft 530 is clamped to the crankshaft sleeve 413 through the connecting shaft 420, realizing the force conversion between the flip bed 300 and the connecting rod 510 through the connecting rod shaft 530. When it is necessary to manually flip the flip bed 300 from the first position a1 to the second position a2, the power assist component 520 will be decompressed and gradually extended, releasing the elastic potential energy. The connecting rod 510 transmits the elastic potential energy released by the power assist component 520 to the connecting rod shaft 530, and the connecting rod shaft 530 converts the elastic force into a torque acting on the flip bed 300, playing a power assist role; when the flip bed 300 flips from the second position a2 to the third position a3 or flips back from the second position a2 to the first position a1, the power assist component 520 can provide a buffer damping effect, making the process of laying flat the bed board 310 smoother.

[0035] Preferably, an O-ring (an annular rubber ring for sealing) and a nylon washer are provided between the connecting shaft 420 and the rotating shaft sleeve 432, and a nylon washer is provided between the rotating shaft sleeve 432 and the crankshaft sleeve 413, which can further play a role in buffering and shock absorption and reduce the noise during the flipping process.

[0036] Refer to Figure 6 、 Figure 10 and Figure 11, a support mechanism 600 is provided on the bed board 310. The support mechanism 600 includes support rods 610, support rod fixings 620 and foot seats 630. There is a pair of support rods 610, which are symmetrically hinged to both sides of the bottom of the bed board 310 respectively, and can be folded or rotated around the hinge points for supporting the bed board 310. Preferably, the support rods 610 are hinged on the side away from the RV, which can achieve a better support effect. The support rod fixings 620 are symmetrically fixed on both sides of the bottom of the bed board 310 and are collinear with the axis of the support rods 610 for restricting the position of the support rods 610 after folding. In this embodiment, it is preferably an elastic C-shaped clamp, which is provided with a clamping groove that can be clamped with the support rods 610. The foot seats 630 are arranged at one end of the support rods 610 in contact with the ground, which can increase the contact area between the support rods 610 and the ground. Preferably, the foot seats 630 can be set as a horseshoe-shaped structure, providing better stability and being more concise and beautiful at the same time.

[0037] A sofa with a reclining backrest and tableware are installed in the accommodation space 110 of the RV body 100. In other embodiments, the furniture in the accommodation space 110 of the RV body 100 can be adjusted according to requirements. One side edge of the top cover 200 is hinged and flipped on any side wall of the RV body 100 except the side where the folding bed 300 is installed. In this embodiment, it is preferably on the side wall of the RV body 100 away from the folding bed 300. The top cover 200 can also be used as a bed when it is flipped out, and the folding bed 300 is stored inside the RV when not in use. The top cover 200 rotates to open or close the accommodation space 110. The rotation action can generate a downward pressure when the top cover 200 is closed, enhancing the fitting effect of the sealing strip and preventing water seepage. Moreover, the rotatably arranged top cover 200 forms a seamless covering structure for the accommodation space 110 of the RV body 100, improving the sealing effect.

[0038] To facilitate the flipping of the top cover 200, a power-assisted gas spring can be installed on the RV body 100. One end of the power-assisted gas spring is rotatably connected to the outer side wall of the RV body 100, and the other end is rotatably connected to the side wall of one end of the top cover 200 for providing assistance when the top cover 200 rotates.

[0039] The working principle of this embodiment is as follows: When the flipping bed 300 is located inside the RV, the gas spring is in a compressed state. When it is needed to be used, first flip the top cover 200 to open the accommodation space 110, and then flip the bed board 310 outwards to the second position a2. During this process, the gas spring gradually releases compression to generate a thrust force, and the thrust force is converted into a torque acting on the bed board 310 through the connecting rod shaft 530, so that the flipping operation can be realized without the need for a large force to be applied to the bed board 310 by manual labor, and the process is more labor-saving; Subsequently, rotate the support rod 610 to be perpendicular to the bed board 310, and then flip the bed board 310 outwards to the first position a1. During this process, the gas spring is gradually compressed, which can provide buffer damping; Finally, support the support rod 610 on the ground and turn over the sofa backrest. At this time, both the sofa and the bed board 310 can be used normally. When it is no longer needed, operate in the reverse direction. During the process of the bed board 310 flipping from the first position a1 to the second position a2, the gas spring provides an assisting effect; During the process of the bed board 310 flipping from the second position a2 to the third position a3, the gas spring provides buffer damping, which will not be elaborated here. After reaching the third position a3, the gas spring reaches the minimum stroke and cannot be compressed further, thus restricting the bed board 310 at the third position a3. During the whole flipping process, the gas spring always plays a positive role. In addition, when the bed board 310 is at the third position a3, the bed board 310 just abuts against the laid-back sofa backrest, which can further restrict the position of the bed board 310 and make its stability better.

[0040] The above are all the preferred embodiments of this application. The protection scope of this application is not limited thereby. Therefore, all equivalent changes made according to the structure, shape, and principle of this application should be covered within the protection scope of this application.
