[0002] An RV is a vehicle that combines a house and a car, providing travel, accommodation, dining, entertainment, and mobile office space. With the rise of self-drive tours and camping in recent years, demand for RVs has rapidly increased among families and campground operators.

[0003] At present, the Chinese utility model patent application with application number 202222032774.5 and publication date of August 8, 2022 proposes an electric and manual integrated sun visor for RVs, comprising a fixing box, one end of which is equipped with two spring struts, and one end of which is equipped with a mounting plate, a servo motor is mounted on one side of the fixing box by bolts, and the output end of the servo motor extends to the interior of the fixing box where an active bevel gear is mounted, a rotating rod is mounted between the upper and lower ends of the interior of the fixing box, and a driven bevel gear is welded to the bottom end of the outer wall of the rotating rod, and a worm sleeve is welded to the top end of the outer wall of the rotating rod. The utility model manually rotates a knob, and the knob drives the card plate to rotate through the active rod, causing the card plate to apply thrust to the card slot, thereby causing the rotating rod to rotate, completing the drive of the winding roller, thereby manually controlling the device, and being able to open and close the awning when the servo motor fails to work.

[0004] Regarding the above technical solution, the inventor believes that after rain, the awning tarpaulin is not dried in time and is rolled up by the winding roller. In hot weather, it is easy for mold attached to the tarpaulin to multiply in large numbers, discharge acidic substances, and produce odor, thereby increasing the harm to the tourists' bodies. Summary of the Invention

[0005] In order to solve the problems mentioned in the background technology, the present invention provides a telescopic mechanism applied to a recreational vehicle and a recreational vehicle.

[0006] The present invention provides a telescopic mechanism for a recreational vehicle and a recreational vehicle, which adopts the following technical solutions:

[0007] In the first aspect, the present invention provides a telescopic mechanism for a motorhome, including a storage box, a sunshade, a rotating mechanism and a lifting mechanism. The rotating mechanism includes a first support rod, a second support rod, a third support rod, a support plate, a slide rail, a slide rail bracket and a power assembly. The support plate is slidably connected in the storage box, and the lifting mechanism is used to drive the support plate to rise and fall. The slide rail bracket is set on the support plate, and the slide rail is set on the slide rail bracket. The first support rod is fixedly connected to the slide rail, and the second support rod and the third support rod are both rotatably connected to the slide rail. The sunshade is set on the first support rod, the second support rod and the third support rod, and the power assembly is used to drive the third support rod to rotate on the slide rail.

[0008] By adopting the above technical solution, the sunshade cloth is connected to the first support rod, the second support rod and the third support rod. When the sunshade cloth needs to be opened, the support plate is raised by the lifting mechanism, so that the first support rod, the second support rod, the third support rod and the slide rail are moved out of the storage box. Then, the third support rod is driven to rotate on the slide rail by the power component, and the first support rod drives the second support rod to rotate, so that the sunshade cloth between the third support rod and the second support rod is unfolded. Under the drive of the first support rod, multiple second support rods unfold the sunshade cloth between multiple second support rods. When the first support rod and the second support rod are fully unfolded, the sunshade cloth forms a fan-shaped awning under the support of the first support rod and the second support rod. Such an arrangement can The awning's shading area can be adjusted at will, and the awning can be adjusted according to the direction of sunlight. When the awning needs to be folded up under windy and rainy weather conditions, the power component drives the third support rod box to rotate in the direction of the second support, so that the sunshade cloth between the second support rod and the third support rod is folded, and the sunshade cloth between multiple second support rods is folded until the third support rod is close to the first support rod, and then the lifting mechanism drives the support plate to descend, so that the sunshade cloth is moved into the storage box. Since the sunshade cloth is still supported by the first support rod, the second support rod and the third support rod after it is folded, the sunshade cloth is in a storage box with good ventilation, thereby reducing the probability of odor generation in an environment with high humidity, thereby reducing harm to the bodies of tourists.

[0009] Optionally, the power assembly includes a slider, a bearing column, a reduction motor, a pulley, a first pulley bracket and a second pulley bracket, the slide rail is provided with a slide groove, the slider is provided with multiple, the slider is slidably connected in the slide groove, the second support rod and the third support rod are both provided on the slider, and the slide rail is also provided with a slide, the reduction motor is provided on the support plate, the bearing column is rotatably connected to the output shaft of the reduction motor, one end of the first pulley bracket is provided on the bearing column, the pulley is provided on the first pulley bracket, and the pulley is slidably connected to the slide rail through the slide, one end of the second pulley bracket is provided on the end of the pulley away from the first pulley bracket, and the other end of the second pulley bracket is provided on the slider.

[0010] By adopting the above technical solution, when the sunshade needs to be opened, the reduction motor drives the supporting column to rotate, and the supporting column drives the pulley to move along the slide rail through the first pulley bracket. During the movement, the pulley drives the second pulley bracket to rotate with the supporting column as the center of the circle, and the second pulley bracket drives the third support rod to rotate with the supporting column as the center of the circle, so that the sunshade between the first support rod, the second support rod and the third support rod is unfolded. Due to the setting of the power component, the sunshade can be automatically retracted and extended when unfolding or storing, and thus can be quickly retracted and extended. The setting of the slider provides the second support rod with a fulcrum, reducing the probability of the second support rod drooping away from one end of the supporting column.

[0011] Optionally, the rotating mechanism further includes a clamping rod, and a clamping slot is provided on each of the first support rod, the second support rod and the third support rod. There are multiple clamping rods, and the clamping rod is clamped on the first support rod, the second support rod and the third support rod through the clamping slot.

[0012] By adopting the above technical solution, when installing the sunshade cloth, the third support rod is driven to rotate by the reduction motor so that the angle between the third support rod and the first support rod reaches the maximum, and then the sunshade cloth is stretched out, and the two ends of the sunshade cloth are first pressed in the slot through the clamping rod, and then the sunshade cloth is divided into equal parts according to the number of the second support rods, and the remaining sunshade cloth is pressed into the slot on the second support rod through the clamping rod according to the equal division points of the cloth. Since when installing the sunshade cloth, the sunshade cloth only needs to be connected to the first support rod, the second support rod and the third support rod through the clamping rod, the installation efficiency of the sunshade cloth is thereby improved.

[0013] Optionally, a pull ring is fixedly connected to the clamping rod, and a plurality of pull rings are provided, and each clamping rod is correspondingly connected to a pull ring.

[0014] By adopting the above technical solution, when the sunshade cloth is exposed to wind, rain and sun for a long time and becomes damaged, the pull ring can be pulled to drive the connecting rod to slide out of the slot, and then the damaged sunshade cloth can be removed. Due to the setting of the pull ring, the steps for replacing the sunshade cloth are reduced, thereby improving the replacement efficiency of the sunshade cloth.

[0015] Optionally, the rotating mechanism further includes a support leg, and the second support rod and the third support rod are both movably connected with a support leg.

[0016] By adopting the above technical solution, when the sunshade cloth is unfolded, the legs are taken out from the RV so that the legs respectively support the second support rod and the end of the third support rod away from the load-bearing column, thereby improving the stability of the sunshade cloth.

[0017] Optionally, the lifting mechanism includes a first electric push cylinder and a guide column. The first electric push cylinder is arranged in a storage box. The output end of the first electric push cylinder is transmission-connected to the support plate. A through hole is provided on the support plate. The guide column is arranged in the storage box. The support plate slides to be connected to the guide column through the through hole.

[0018] By adopting the above technical solution, when the output end of the first electric push cylinder pushes the support plate up and down, the support plate moves along the length direction of the guide column, and the guide column limits the support plate, thereby preventing the support plate from rotating when the reduction motor starts.

[0019] Optionally, a second electric push cylinder is provided on the storage box, a sealing cover is slidably connected to the storage box, a push plate is provided on the sealing cover, and an output end of the second electric push cylinder is transmission-connected to the push plate.

[0020] By adopting the above technical solution, when the sunshade cloth is stored in the storage box in windy and rainy weather, the second electric push cylinder pushes the sealing cover to slide through the push plate, so that the sealing cover covers the storage box to seal the storage box, thereby reducing the impact of rain on the sunshade cloth and extending the service life of the sunshade cloth.

[0021] In a second aspect, the present invention provides a motorhome, comprising a motorhome body and a drying system, the drying system comprising an air conditioner and an air duct, the air conditioner being arranged on the motorhome body, an air inlet being provided on the storage box, one end of the air duct being connected to the exhaust port of the air conditioner, and the other end of the air duct being connected to the air inlet.

[0022] By adopting the above technical solution, when the sunshade cloth is still in a moist state after being stored in the storage box, the air conditioner outdoor unit can blow the air in the RV room to the sunshade cloth through the air duct, thereby drying the sunshade cloth and reducing the probability of the sunshade cloth generating odor.

[0023] Optionally, it also includes a floor heating system, which includes a heating plate, a water tank, a water pump, a main line, a circulation line and a return line. The water tank is arranged in the RV body, and the heating plate is arranged in the water tank. The water pump, the main line, the circulation line and the return line are all arranged in the RV body. The water tank is provided with a water filling port, a water inlet and a drain port. One end of the main line is connected to the drain port of the water tank, the other end of the main line is connected to the water inlet of the water pump, one end of the circulation line is connected to the water outlet of the water pump, one end of the road return line is connected to the other end of the circulation line, and the other end of the return line is connected to the water tank through the water inlet.

[0024] By adopting the above technical solution, when the weather is cold, water can be filled into the water tank through the water inlet box, and the heating plate heats the water in the water tank. After heating, the large amount of water flows back to the water tank through the main pipe and the return pipe under the drive of the water pump, and then the interior of the RV body can be heated, thereby improving the comfort inside the RV body in colder climates.

[0025] Optionally, the floor heating system further includes a temperature monitor, which is disposed in the main body of the RV, and the water pump and the heating plate are both electrically connected to the temperature monitor.

[0026] By adopting the above technical solution, the optimal comfortable temperature felt by the human body is input into the temperature monitor. When the temperature monitor detects that the internal temperature of the RV body reaches the comfortable temperature, the temperature monitor transmits the signal to the heating plate and the water pump, and the heating plate and the water pump stop working. This setting can save energy loss.

[0027] In summary, the present invention includes at least one of the following beneficial technical effects:

[0028] The knocking ball strikes the medical instrument, thereby shaking off the dust on the medical detection instrument. Due to the arrangement of the connecting rope and the winding drum, the knocking ball can strike the medical detection instrument multiple times, thereby improving the efficiency of dust cleaning.

[0029] The fixing component fixes the gear. When the winding drum stops rotating, the fixing component releases the fixing plate of the winding drum until the teeth on the belt drive the gear to rotate again. The setting of the wire column makes the end of the connecting rope close to the winding drum in a straight state when the winding drum stops rotating, thereby making it difficult for the winding drum to get tangled when winding the connecting rope again.

[0030] Due to the setting of the first limit plate and the second limit plate, the sliding rod slides along the axial direction of the sleeve when sliding, thereby reducing the probability that the first spring will have difficulty in pushing the sliding rod out due to the deviation of the sliding direction of the sliding rod. When the sliding rod slides out, the second limit plate blocks the first limit plate, thereby reducing the probability of the sliding rod sliding out of the sleeve. BRIEF DESCRIPTION OF THE DRAWINGS

[0039] The following is combined with Figure 1 -Attached Figure 7 The present invention is described in further detail.

[0040] The embodiment of the present invention discloses a telescopic mechanism for a recreational vehicle and the recreational vehicle. Figure 1-Figure 7 A telescopic mechanism used in RVs includes a storage box 1, a sunshade cloth 2, a rotating mechanism 3, and a lifting mechanism 6. The sunshade cloth 2 is movably arranged in the storage box 1, the rotating mechanism 3 is used to drive the sunshade cloth 2 to rotate and unfold, and the lifting mechanism 6 is used to drive the rotating mechanism 3 to rotate.

[0041] Reference Figure 1-Figure 5The first and second support rods 31 and 32 are connected to each other through the guide rails 35, and the second and third support rods 33 are connected to each other through the guide rails 35. The first and second pulley brackets 375 are connected to each other through the guide rails 374 and 376, respectively.

[0042] The sunshade cloth 2 is connected to the first support rod 31, the second support rod 32 and the third support rod 33. When the sunshade cloth 2 needs to be opened, the support plate 34 is raised by the lifting mechanism 6, so that the first support rod 31, the second support rod 32, the third support rod 33 and the slide rail 35 are moved out of the storage box 1, and the reduction motor 373 drives the supporting column 372 to rotate. The supporting column 372 drives the pulley 374 to move along the slide rail 35 through the first pulley bracket 375. During the movement, the pulley 374 drives the second pulley bracket 376 to support The supporting column 372 rotates as the center of the circle, and the second pulley bracket 376 drives the third support rod 33 to rotate with the supporting column 372 as the center of the circle, so that the sunshade cloth 2 between the first support rod 31, the second support rod 32 and the third support rod 33 is unfolded. Such an arrangement can adjust the sunshade area of ​​the awning at will, and the awning can be adjusted according to the direction of sunlight. When the awning needs to be folded up under windy and rainy weather conditions, the reduction motor 373 drives the supporting column 372 to rotate in the opposite direction, and the supporting column 372 drives the pulley 374 on the slide rail 35 along the first pulley bracket 375. When the slide moves, the pulley 374 drives the second pulley bracket 376 to rotate with the supporting column 372 as the center of the circle. The second pulley bracket 376 drives the third support rod 33 to rotate with the supporting column 372 as the center of the circle, so that the sunshade cloth 2 between the second support rod 32 and the third support rod 33 is folded, so that the sunshade cloth 2 between the multiple second support rods 32 is folded until the third support rod 33 is close to the first support rod 31. Then the lifting mechanism 6 drives the support plate 34 to descend, so that the sunshade cloth 2 moves into the storage box 1. Since the sunshade cloth 2 is folded, The sunshade cloth 2 is still supported by the first support rod 31, the second support rod 32 and the third support rod 33. The sunshade cloth 2 is in the storage box 1 with good ventilation, thereby reducing the probability of generating odor in an environment with high humidity, thereby reducing harm to the body of tourists. When the sunshade cloth 2 is stored in the storage box 1 in windy and rainy weather, the second electric push cylinder 7 pushes the sealing cover 72 to slide through the push plate 71, so that the sealing cover 72 covers the storage box 1 to seal the storage box 1, thereby reducing the impact of rain on the sunshade cloth 2, thereby extending the service life of the sunshade cloth 2.

[0043] Reference Figure 2 and Figure 5 The rotating mechanism 3 also includes a clamping rod 38 and a support leg 4. A clamping slot 39 is provided on the first support rod 31, the second support rod 32 and the third support rod 33. There are multiple clamping rods 38. The clamping rods 38 are clamped on the first support rod 31, the second support rod 32 and the third support rod 33 through the clamping slot 39. A pull ring 5 is fixedly connected to the clamping rod 38. There are multiple pull rings 5. Each clamping rod 38 is connected to a corresponding pull ring 5. The second support rod 32 and the third support rod 33 are movably connected to the support leg 4.

[0044] When installing the sunshade cloth 2, the third support rod 33 is driven to rotate by the reduction motor 373 so that the angle between the third support rod 33 and the first support rod 31 reaches the maximum, and then the sunshade cloth 2 is stretched out, and the two ends of the sunshade cloth 2 are first pressed into the card slot 39 through the clamping rod 38, and then the sunshade cloth 2 is divided into equal parts according to the number of the second support rods 32, and the remaining sunshade cloth 2 is pressed into the card slot 39 on the second support rod 32 through the clamping rod 38 according to the equal division points of the cloth. Since when installing the sunshade cloth 2, it is only necessary to connect the sunshade cloth 2 to the first support rod 31, the second support rod 32 and the third support rod 33 through the clamping rod 38, thereby improving the installation efficiency of the sunshade cloth 2. When the sunshade 2 is exposed to wind, rain, and sun for a long time and becomes damaged, the pull ring 5 can be pulled to cause the connecting rod 38 to slide out of the locking groove 39, thereby removing the damaged sunshade 2. Due to the provision of the pull ring 5, the steps for replacing the sunshade 2 are reduced, thereby improving the replacement efficiency of the sunshade 2. When the sunshade 2 is unfolded, the legs 4 are taken out of the RV so that the legs 4 support the ends of the first support rod 31, the second support rod 32, and the third support rod 33 away from the bearing column 372, thereby improving the stability of the sunshade 2.

[0045] Reference Figure 5 The lifting mechanism 6 includes a first electric push cylinder 61 and a guide column 62. The first electric push cylinder 61 is arranged in the storage box 1. The output end of the first electric push cylinder 61 is transmission-connected to the support plate 34. A through hole is provided on the support plate 34. The guide column 62 is arranged in the storage box 1. The support plate 34 slides to be connected to the guide column 62 through the through hole. When the output end of the first electric push cylinder 61 pushes the support plate 34 up and down, the support plate 34 moves along the length direction of the guide column 62. The guide column 62 limits the support plate 34, thereby preventing the support plate 34 from rotating when the reduction motor 373 is started.

[0046] Reference Figure 2 、 Figure 6 and Figure 7A motorhome, comprising a motorhome body 8, a drying system 10 and a floor heating system 9, wherein the drying system 10 comprises an air conditioner 101 and an air duct 102, wherein the air conditioner 101 is arranged on the motorhome body 8, and an air inlet is opened on the storage box 1, one end of the air duct 102 is connected to the exhaust port of the air conditioner 101, and the other end of the air duct 102 is connected to the air inlet; the floor heating system 9 comprises a heating plate 91, a water tank 92, a water pump 93, a main line 94, a circulation line 95, a return line 96 and a temperature monitor 97, wherein the water tank 92 is arranged in the motorhome body 8, the heating plate 91 is arranged in the water tank 92, the water pump 93, the main line 94, the circulation line 95, the return line 96 and the temperature monitor 97 The pipeline 94, the circulation pipeline 95 and the return pipeline 96 are all arranged in the RV body 8. The water tank 92 is provided with a water filling port, a water inlet and a drain port. One end of the main pipeline 94 is connected to the drain port of the water tank 92, and the other end of the main pipeline 94 is connected to the water inlet of the water pump 93. One end of the circulation pipeline 95 is connected to the water outlet of the water pump 93. One end of the return pipeline 96 is connected to the other end of the circulation pipeline 95. The other end of the return pipeline 96 is connected to the water tank 92 through the water inlet. The temperature monitor 97 is arranged in the RV body 8. The water pump 93 and the heating plate 91 are both electrically connected to the temperature monitor 97.

[0047] When the sunshade cloth 2 remains damp after being stored in the storage box 1, the air conditioner 101 can blow air from the interior of the RV through the air duct 102 to the sunshade cloth 2, thereby drying the sunshade cloth 2 and reducing the likelihood of odor from the sunshade cloth 2. In cold weather, water can be added to the water tank 92 through the water inlet box. The heater 91 heats the water in the water tank 92. The heated water flows through the main pipe 94, driven by the water pump 93, through the circulation management and return pipe 96, back to the water tank 92, thereby heating the interior of the RV body 8 and improving the comfort level within the RV body 8 in cold weather. The optimal comfortable temperature perceived by the human body is input into the temperature monitor 97. When the temperature monitor 97 detects that the temperature inside the RV body 8 has reached the comfortable temperature, the temperature monitor 97 transmits a signal to the heater 91 and water pump 93, causing them to stop operating. This configuration can save energy loss.

[0048] The implementation principle of a telescopic mechanism applied to a recreational vehicle and the recreational vehicle according to an embodiment of the present invention is as follows:

[0049] When installing the sunshade cloth 2, the third support rod 33 is driven to rotate by the reduction motor 373 so that the angle between the third support rod 33 and the first support rod 31 reaches the maximum, and then the sunshade cloth 2 is stretched out, and the two ends of the sunshade cloth 2 are first pressed into the card slot 39 through the clamping rod 38, and then the sunshade cloth 2 is divided into equal parts according to the number of the second support rods 32, and the remaining sunshade cloth 2 is pressed into the card slot 39 on the second support rod 32 through the clamping rod 38 according to the equal division points of the cloth. Since when installing the sunshade cloth 2, it is only necessary to connect the sunshade cloth 2 to the first support rod 31, the second support rod 32 and the third support rod 33 through the clamping rod 38, thereby improving the installation efficiency of the sunshade cloth 2. When the sunshade 2 is damaged after being exposed to wind, rain and sun for a long time, the pull ring 5 can be pulled to cause the connecting rod 38 to slide out of the locking groove 39, thereby removing the damaged sunshade 2. Due to the provision of the pull ring 5, the steps for replacing the sunshade 2 are reduced, thereby improving the replacement efficiency of the sunshade 2. When the sunshade 2 is unfolded, the support legs 4 are taken out of the RV so that the support legs 4 support the ends of the first support rod 31, the second support rod 32 and the third support rod 33 away from the bearing column 372, thereby improving the stability of the sunshade 2.

[0050] After the sunshade cloth 2 is connected to the first support rod 31, the second support rod 32 and the third support rod 33, when the sunshade cloth 2 needs to be opened, the support plate 34 is raised by the lifting mechanism 6, so that the first support rod 31, the second support rod 32, the third support rod 33 and the slide rail 35 are moved out of the storage box 1, and the reduction motor 373 drives the supporting column 372 to rotate, and the supporting column 372 drives the pulley 374 to move along the slide on the slide rail 35 through the first pulley bracket 375, and the pulley 374 drives the second pulley bracket 375 to move along the slide during the movement. The wheel bracket 376 rotates with the supporting column 372 as the center of the circle, and the second pulley bracket 376 drives the third support rod 33 to rotate with the supporting column 372 as the center of the circle, so that the sunshade cloth 2 between the first support rod 31, the second support rod 32 and the third support rod 33 is unfolded. In this way, the sunshade area of ​​the awning can be adjusted at will, and the awning can be adjusted according to the direction of sunlight. When the awning needs to be folded up under windy and rainy weather conditions, the reduction motor 373 drives the supporting column 372 to rotate in the opposite direction, and the supporting column 372 rotates through the first pulley bracket 375 The pulley 374 is driven to move along the slideway on the slide rail 35. During the movement, the pulley 374 drives the second pulley bracket 376 to rotate with the bearing column 372 as the center. The second pulley bracket 376 drives the third support rod 33 to rotate with the bearing column 372 as the center, so that the sunshade cloth 2 between the second support rod 32 and the third support rod 33 is folded, so that the sunshade cloth 2 between the multiple second support rods 32 is folded until the third support rod 33 is close to the first support rod 31. Then the lifting mechanism 6 drives the support plate 34 to descend, so that the sunshade cloth 2 between the second support rod 32 and the third support rod 33 is folded. The cloth 2 is moved to the storage box 1. Since the sunshade cloth 2 is still supported by the first support rod 31, the second support rod 32 and the third support rod 33 after being folded, the sunshade cloth 2 is in the storage box 1 with good ventilation, thereby reducing the probability of generating odor in an environment with high humidity, thereby reducing harm to the body of tourists. When the sunshade cloth 2 is stored in the storage box 1 in windy and rainy weather, the second electric push cylinder 7 pushes the sealing cover 72 to slide through the push plate 71, so that the sealing cover 72 covers the storage box 1 to seal the storage box 1.

[0051] The above are all preferred embodiments of the present invention, and are not intended to limit the scope of protection of the present invention. Therefore, any equivalent changes made based on the structure, shape, and principle of the present invention should be included in the scope of protection of the present invention.
