[0002] With the development of the economy and the improvement of people's living standards, traveling in an RV has become a way of life. However, the interior space of an RV is generally small, and can only accommodate limited living facilities and small beds. Especially when a family goes out to travel, the bed area set up in the RV may not meet the living needs. Therefore, in related technologies, within the limited space of the RV, the rest area and activity area are generally converted in function at different times, and the space used for activities during the day will be placed with a bed board and used as a rest area at night.

[0003] Since the interior space of a general RV is small, and in order to provide users with a larger bed space, a folding method is adopted to achieve a larger bed without taking up too much space. However, most of the current folding methods are rotating or pulling, both of which are horizontal folding; after folding, it will still occupy the space inside the car horizontally. On the other hand, the folding structure is highly movable and is prone to instability during load-bearing, which may cause danger. Summary of the invention

[0006] Preferably, the supporting outer tube is fixedly arranged on the roof, and one end of the supporting outer tube is connected to a water supply pipe, and the water supply pipe runs through the roof; one end of the water supply pipe is connected to a water tank for water replenishment, and a water pump and a heating pipe are arranged inside the water tank.

By providing multiple groups of load-bearing pipes, the area of ​​temperature change can be made larger, further improving the comfort of use. At the same time, using water to change the temperature below the user can be distinguished from directly using electrical appliances, such as electric blankets, and is safer.

[0018] In addition, part of the water inside the horizontal tube will flow into the interior of the inclined tube through the second vertical tube. Since a water leakage ring is provided inside the inclined tube, the water flow rate is limited by the water leakage ring, and the inclined tube is designed to be inclined, the water will fall after passing through the water leakage ring and fall on the inner wall of the inclined tube, making a sound, thereby simulating the sound of flowing water and improving the user's sleep quality. In addition, the water sound, such as the sound of a waterfall or a stream, can be controlled by sliding the second vertical tube and matching the style of the water leakage ring.

[0019] The present invention allows water to flow inside the load-bearing pipe and impact the impeller when passing through it, thereby causing the impeller to rotate. The rotation of the impeller drives the movable shaft to rotate, and the movable shaft drives the fan blades to rotate. The rotation of the fan blades can change the temperature of the bed frame surface, and the water flow can be used to further improve the user's comfort. BRIEF DESCRIPTION OF THE DRAWINGS

The inclined tube 27 slides on the second vertical tube 24, and the two ends of the inclined tube 27 are connected to the second vertical tube 26 and the load-bearing tube 28 respectively, and the two ends of the inclined tube 27 are made of elastic material, and the inclined tube 27 is provided with a supporting water leakage ring 211 that can change the size of the water flow; the water inside the supporting outer tube 22 flows to the inside of the horizontal tube 24 through the supporting inner tube 21, and the water inside the horizontal tube 24 flows to the load-bearing tube 28, and the water inside the load-bearing tube 28 changes the surface temperature of the load-bearing tube 28 while flowing; at the same time, a part of the inside of the load-bearing tube 28 The water flow uses the design of the inclined tube 27 to generate water flow sound; the water flowing inside the load-bearing tube 28 will impact the impeller 36 and then make the impeller 36 rotate, and the rotation of the impeller 36 will drive the fan blades 34 to rotate through the movable shaft 33, so that the fan blades 34 further cooperate with the water flow inside the load-bearing tube 28 to improve the surface temperature of the load-bearing tube 28; one end of the water supply pipe 23 is connected to the water tank for water replenishment, and a water pump and a heating pipe are arranged inside the water tank; one end of the horizontal tube 24 is provided with a groove, and the hose 210 is wound and stored inside the groove;

[0030] See also Figures 1 to 4 As shown, when used inside a motorhome, the bed frame 1 can drive the inner support tube 21 to slide inside the outer support tube 22. After being adjusted to a certain height, bolts can be used to fix the bed frame 1 to maintain stability.

[0031] In addition, when the bed frame 1 is not in use, the bed frame 1 can be retracted to the roof of the vehicle, so that the bed frame 1 can be retracted to the vertical upper space in the vehicle, without occupying too much horizontal space in the vehicle, providing a larger use space in the vehicle, and at the same time different from the folding bed frames on the market, on the one hand, achieving the effect of saving space, on the other hand, the height can be adjusted, and the overall fixed non-folding structure is more stable;

[0032] In addition, during the use of the user, the water tank can be connected to the water supply pipe 23, and the water pump inside the water tank can be used to transfer water to the inside of the water supply pipe 23, and then transferred to the inside of the supporting outer pipe 22 through the water supply pipe 23.

For example, in some environments such as hot and humid, the temperature of the surface of the bed frame 1 can be improved and reduced to improve the comfort of use, or in a cold environment, the water can be heated by the heating pipe inside the water tank, and then the hot water can increase the temperature of the surface of the bed frame 1 through the load-bearing pipe 28 to improve the comfort of the user. By setting multiple groups of load-bearing pipes 28, the area of ​​temperature change can be made larger, further improving the comfort of use; at the same time, using water to change the temperature below the user can be distinguished from directly using electrical appliances, such as electric blankets, and is safer;

[0033] refer to Figure 5 As shown, part of the water inside the horizontal tube 24 will flow into the interior of the inclined tube 27 through the second vertical tube 26. Since a water leakage ring 211 is provided inside the inclined tube 27, and since the water leakage ring 211 limits the water flow rate and the inclined tube 27 is designed to be inclined, the water will fall after passing through the water leakage ring 211 and fall on the inner wall of the inclined tube 27, making a sound, thereby simulating the sound of flowing water and improving the user's sleep quality. In addition, the water sound can be controlled by sliding the second vertical tube 26 and coordinating with the style of the water leakage ring 211. For example, the water sound can be simulated into the sound of a waterfall or a stream by using the water leakage ring 211.

[0034] The bed frame 1 is provided with a ventilation mechanism 3 for assisting the regulating mechanism 2 to complete the water circulation. The ventilation mechanism 3 includes a circulation pipe 31 connected with the load-bearing pipe 28. One end of the circulation pipe 31 is connected with the support tube 29. A movable shaft 33 runs through the inside of the load-bearing pipe 28. An impeller 36 and a fan blade 34 are installed on the surface of the movable shaft 33. The fan blade 34 and the impeller 36 are respectively arranged on the outside and inside of the load-bearing pipe 28; the circulation pipe 31 is fixedly installed on the bed frame 1, and the circulation pipe 31 is connected with a plurality of load-bearing pipes 28. After the water inside the load-bearing pipe 28 flows into the inside of the supporting inner pipe 21, the water inside the circulation pipe 31 flows into the inside of the support tube 29 for storage. The circulation pipe 31 is connected with a third vertical pipe 32. The circulation pipe 31 is connected with the load-bearing pipe 28 through the third vertical pipe 32. The fixed plate 35 is fixedly installed inside the load-bearing pipe 28. The movable shaft 33 runs through the load-bearing pipe 28 and the movable shaft 33 slides on the load-bearing pipe 28. The fixed plate 35 is provided with a limiting rib;

[0035] refer to Figure 5 and Figure 6 as well as Figure 7As shown, while the water flows inside the load-bearing pipe 28, the water flows through the impeller 36 and impacts the impeller 36, which in turn causes the impeller 36 to rotate. The rotation of the impeller 36 drives the movable shaft 33 to rotate, and the movable shaft 33 drives the fan blades 34 to rotate. The temperature of the surface of the bed frame 1 can be changed by the rotation of the fan blades 34, and the user's comfort can be further improved by cooperating with the water flow. At the same time, after the water flows impact the movable shaft 33, it will flow to the third vertical pipe 32, and flow to the circulation pipe 31 through the third vertical pipe 32. Through the circulation pipe 31, the water flows to the inside of the support tube 29 for storage, or when the support tube 29 contacts the bottom of the vehicle, the support tube 29 is connected to the external pipeline, so that the water is discharged to the outside of the vehicle or flows back to the inside of the water tank for circulation or discharge.

[0036] See also Figure 6 As shown, the fan blades 34 can be replaced with a massage head. When the movable shaft 33 is rotated by the impact of water, the movable shaft 33 can drive the massage head to rotate. The rotation of the massage head can massage the user, thereby improving the user's comfort.

[0037] In addition, the use of hot water mentioned in the overall concept of the present technical solution can be obtained through external natural resources and can be added by oneself; at the same time, the use of hot water can also be used as a backup water source; in winter, the hot water is used to flow inside the load-bearing pipe 28 to warm the bed, and then the hot water enters the support tube 29 for storage, thereby completing the bed warming task; after the user gets up, the bed frame 1 is adjusted to the roof, and a valve can be set on one side of the support tube 29, so that the support tube 29 is also raised to the roof position with the bed frame 1. At this time, the user can use the valve set on one side of the support tube 29 to use the hot water stored in the support tube 29 for brushing teeth and washing face after getting up in the morning, thereby reducing the operation of boiling water after the user gets up, thereby allowing the hot water after warming the bed to be reused, which is cleverly designed and saves resources.

[0038] Working principle: When in use, the bed frame 1 can drive the inner support tube 21 to slide inside the outer support tube 22. After adjusting to a certain height, bolts can be used to fix the bed frame 1 to maintain stability. When the bed frame 1 is not in use, the bed frame 1 is retracted to the roof of the vehicle, so that the bed frame 1 can be retracted to the vertical upper space inside the vehicle, without occupying too much horizontal space inside the vehicle, providing a larger use space inside the vehicle.

[0039] During use, the water tank can be connected to the water supply pipe 23, and the water pump inside the water tank can be used to transfer water to the inside of the water supply pipe 23, and then transferred to the inside of the supporting outer pipe 22 through the water supply pipe 23. The water flows along the supporting outer pipe 22 to the inside of the hose 210, and then moves to the inside of the horizontal pipe 24 through the hose 210, and passes through the inside of the first vertical pipe 25 and the load-bearing pipe 28. In this way, the temperature of the surface of the bed frame 1 can be improved by the temperature of the water. For example, in some environments such as hot and humid weather, the temperature of the surface of the bed frame 1 can be improved and reduced, thereby improving the comfort of use.

[0040] In addition, part of the water inside the horizontal tube 24 will flow into the interior of the inclined tube 27 through the second vertical tube 26. Since a water leakage ring 211 is provided inside the inclined tube 27, and since the water leakage ring 211 limits the water flow rate and the inclined tube 27 is designed to be inclined, the water will fall after passing through the water leakage ring 211 and fall on the inner wall of the inclined tube 27, making a sound, thereby simulating the sound of flowing water and improving the user's sleep quality. In addition, the water sound, such as the sound of a waterfall or a stream, can be controlled by sliding the second vertical tube 26 and coordinating the style of the water leakage ring 211.

[0041] When the water flows inside the load-bearing pipe 28, the water will impact the impeller 36 when passing through the impeller 36, thereby causing the impeller 36 to rotate. The rotation of the impeller 36 will drive the movable shaft 33 to rotate, and the movable shaft 33 will drive the fan blades 34 to rotate. The rotation of the fan blades 34 can change the temperature of the surface of the bed frame 1, and the water flow will further improve the user's comfort. At the same time, after the water impacts the movable shaft 33, it will flow to the third vertical pipe 32, and then flow to the circulation pipe 31 through the third vertical pipe 32. The water flows to the inside of the support tube 29 through the circulation pipe 31 for storage.

[0042] In winter, hot water is used to flow inside the load-bearing tube 28 to warm the bed, and then the hot water is stored in the support tube 29, thereby completing the bed warming task; after the user gets up, the bed frame 1 is adjusted to the roof of the vehicle, and a valve can be set on one side of the support tube 29, so that the support tube 29 is also raised to the roof position with the bed frame 1. At this time, the user can use the valve set on one side of the support tube 29 to use the hot water stored in the support tube 29 to brush teeth and wash face after getting up in the morning.

[0043] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
