Description

Technical Field

[0001] This application relates to the technical field of motorhomes, and in particular to a motorhome pop-up roof device. Background Technology

[0002] A motorhome is a special type of vehicle that can both travel on the road and provide living space. Currently, with the development of the motorhome industry, in order to meet diverse living needs and comply with national regulations requiring motorhomes to have a certain interior space, motorhomes are being designed to be increasingly taller to increase interior space. However, due to height restrictions in various cities, the roofs of these taller motorhomes are usually designed to be adjustable.

[0003] The current technology discloses a pop-top RV, which includes a vehicle body, an electric lifting cylinder on the vehicle body, and a movable top plate on the output end of the electric lifting cylinder. Driving the electric lifting cylinder can raise the top plate to complete the pop-top of the RV.

[0004] Regarding the aforementioned solutions, the inventors believe that the following drawbacks exist: on the one hand, after the roof of the RV is raised, it is inconvenient for the RV to drive through height-restricted road sections; on the other hand, if the roof of the RV is not raised, the interior space of the RV is too small to accommodate people. Summary of the Invention

[0005] In order to ensure that the RV can still accommodate people after the roof is lowered to meet the height restriction requirements, this application provides an RV pop-up roof device.

[0006] The RV pop-up roof device provided in this application adopts the following technical solution:

[0007] A motorhome pop-top device includes a base plate, a lifting drive component on the base plate, and a top plate on the output end of the lifting drive component.

[0008] The lifting drive includes a first cylinder, a second cylinder, and a lifting rod arranged in sequence. One end of the second cylinder is slidably disposed inside the first cylinder, and one end of the lifting rod is slidably disposed inside the second cylinder.

[0009] The second cylinder includes a first piston located inside the first cylinder. The first piston divides the internal space of the first cylinder into a first chamber and a second chamber. The first cylinder has a first oil port and a second oil port. The first oil port communicates with the first chamber, and the second oil port communicates with the second chamber.

[0010] The lifting rod includes a second piston located inside the second cylinder. The second piston divides the internal space of the second cylinder into a third chamber and a fourth chamber. The first piston has a through hole, and the third chamber communicates with the first chamber through the through hole. The second cylinder has a third oil port, which communicates with the fourth chamber.

[0011] By adopting the above technical solution, a two-stage lifting mechanism for the roof can be achieved. Specifically, the actions are as follows: oil enters through the first oil port and exits through the third oil port. The oil entering the first chamber through the first oil port passes through a through-hole into the third chamber, pushing the second piston and causing the lifting rod to move the roof. At this time, the second cylinder remains stationary. Then, oil exits from the third oil port and exits from the second oil port, pushing the first piston and causing the second cylinder to move. The lifting rod then moves the roof again. This action enables the roof to lift in two stages, allowing the roof to lower partially, thus ensuring that the RV can still accommodate passengers while meeting height restrictions. Furthermore, the lowering and raising height of the roof can be flexibly adjusted by controlling the oil inflow and outflow from the first, second, and third oil ports.

[0012] Preferably, the base plate is further provided with a mounting housing, the mounting housing is provided with a lifting member, and the output end of the lifting member is provided with a first support mechanism and a second support mechanism. The first support mechanism is used to support the output end of the lifting member, and the second support mechanism is used to support the top plate.

[0013] The first support mechanism includes a guide component and a locking component. The guide component is located on the output end of the lifting member and is used to guide the movement direction of the output end of the lifting member. The locking component is located inside the mounting housing and is used to lock and support the output end of the lifting member.

[0014] By adopting the above technical solution, after the lifting drive component lifts the top plate, the driving lifting component can drive the first support mechanism and the second support mechanism to move. The first support mechanism can support the output end of the lifting component, while the second support mechanism installed on the output end of the lifting component can support the top plate. The combination of the first support mechanism and the second support mechanism can maximize the load-bearing capacity of the top plate, thereby maximizing the load-bearing capacity of the RV roof. The guide component can guide the movement of the output end of the lifting component, and the locking component can lock and support the guide component, thereby locking and supporting the output end of the lifting component.

[0015] Preferably, the guide assembly includes a mounting base, which is disposed on the output end of the lifting member; a first support rod is movably mounted on the mounting base, and a slider is movably mounted on the end of the first support rod away from the mounting base; a sliding groove is formed on the inner wall of the mounting housing, and the slider is engaged in the sliding groove and can slide along the moving direction of the lifting member.

[0016] By adopting the above technical solution, when the output end of the lifting component moves, the slider will slide in the groove to guide the movement of the output end of the lifting component.

[0017] Preferably, the locking assembly includes a mounting block disposed on the mounting housing. The mounting block has a sliding hole, and a sliding rod passes through the sliding hole. The sliding rod can slide along the moving direction of the lifting member. The top end of the sliding rod is connected to the slider through a connecting block. A first engaging member is hinged to the side wall of the sliding rod near the bottom end. A second engaging member is hinged to the end of the first engaging member away from the sliding rod. The end of the second engaging member away from the first engaging member is hinged to the mounting block.

[0018] By adopting the above technical solution, the sliding rod connected to the slider will move under the action of the slider. At this time, the first and second locking parts that are hinged to each other can limit the movement of the sliding rod.

[0019] Preferably, the sliding rod has a first limit position and a second limit position under the action of the slider, the first limit position being higher than the second limit position; when the sliding rod is in the first limit position, the second engaging member can engage the first engaging member; when the sliding rod is in the second limit position, the second engaging member can engage the sliding rod.

[0020] By adopting the above technical solution, when the sliding rod is in the first extreme position, the top plate is lifted by the lifting drive component. At this time, the second locking component can lock the first locking component. When the sliding rod is in the second extreme position, the top plate is lowered by the lifting drive component. At this time, the second locking component locks the sliding rod. The above design allows the locking component to have a small external size regardless of whether the sliding rod is in the first extreme position or the second extreme position.

[0021] Preferably, a locking member is rotatably provided on the second engaging member, the locking member being used to restrict the rotation of the second engaging member, thereby restricting the movement of the sliding rod.

[0022] By adopting the above technical solution, the locking component can rotate to restrict the movement of the sliding rod, thereby locking the sliding rod to maintain the first limit position or the second limit position.

[0023] Preferably, the second support mechanism includes a fixed base, which is disposed on the output end of the lifting member. The fixed base is provided with a plurality of second support rods, and the end of each second support rod away from the fixed base is disposed on the top plate.

[0024] By adopting the above technical solution, several second support rods can provide support for the top plate.

[0025] Preferably, each of the second support rods on the top plate has a sliding groove extending toward the center of the top plate; each of the second support rods is hinged to the fixed base; each of the second support rods has a sliding member at the end away from the lifting member; the sliding member is engaged in the sliding groove; and the lifting member can drive several sliding members to slide, thereby causing several second support rods to converge.

[0026] By adopting the above technical solution, when the top plate is raised, the lifting component can be driven to move the fixed base, thereby bringing together several second support rods and reducing the space occupied by several second support rods.

[0027] Preferably, a plurality of the second support rods are evenly distributed along the circumferential direction.

[0028] By adopting the above technical solution, the supporting force of the several second support rods arranged in this way on the top plate can be distributed relatively evenly.

[0029] Preferably, the fixed base is higher than the mounting base, and the top of the mounting base is provided with a plurality of load-bearing columns, with the end of each load-bearing column away from the mounting base located at the bottom of the fixed base.

[0030] By adopting the above technical solution, the several load-bearing columns enable the first support mechanism to not only support the output end of the lifting component, but also to directly support the second support mechanism.

[0031] In summary, the present invention has at least one of the following beneficial technical effects:

[0032] 1. Capable of two-stage lifting of the roof panel, specifically the following actions: Oil enters through the first oil port and exits through the third oil port. The oil entering the first chamber through the first oil port passes through the through hole into the third chamber, pushing the second piston to move, thereby causing the lifting rod to move the roof panel. At this time, the second cylinder does not move. Then, oil stops exiting from the third oil port, and oil exits from the second oil port. This oil pushes the first piston to move, thereby causing the second cylinder to move, and the lifting rod to move the roof panel again. The above actions allow the roof panel to lower the vehicle roof slightly, thus allowing passengers to be accommodated inside the RV even after meeting height restrictions.

[0033] 2. After the lifting drive unit lifts the top plate, the driving lifting unit can drive the first support mechanism and the second support mechanism to move. The first support mechanism can support the output end of the lifting unit, while the second support mechanism installed on the output end of the lifting unit can support the top plate. The combination of the first support mechanism and the second support mechanism can maximize the load-bearing capacity of the top plate.

[0034] 3. The rotating locking component can restrict the movement of the sliding rod, thereby locking the sliding rod to the first or second limit position, thus limiting the movement of the slider;

[0035] 4. When the top plate is raised, it can drive the lifting component to move the fixed base, thereby bringing together several second support rods and reducing the space occupied by several second support rods. Attached Figure Description

Detailed Implementation

[0046] The present invention will be further described in detail below with reference to the accompanying drawings.

[0047] In the description of this invention, it should be understood that the orientation descriptions, such as up, down, front, back, left, right, etc., are based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limiting this invention.

[0048] Reference Figure 1 This application is based on the two-stage lifting of the roof by installation on a vehicle. The vehicle includes a vehicle body 1 and a roof mounting plate 11. This application is installed on the vehicle body 1 and the top of this application is connected to the roof mounting plate 11. By driving this application, the roof mounting plate 11 can be lifted and lowered in two stages.

[0049] This application discloses a pop-up roof device for a motorhome. (Refer to...) Figure 1 and Figure 2 The RV pop-up roof device includes a base plate 2 and a top plate 4 arranged sequentially from bottom to top. The base plate 2 is installed on the vehicle body 1, and the top plate 4 is attached to the bottom end of the roof mounting plate 11. The top of the base plate 2 is provided with four lifting drive components 3, which are located at the four corners of the base plate 2. The output end of each lifting drive component 3 is connected to the bottom end of the top plate 4. By driving the four lifting drive components 3 to work synchronously, the top plate 4 can be driven to perform a two-stage lifting and lowering, thereby driving the roof mounting plate 11 to perform a two-stage lifting and lowering.

[0050] Reference Figure 2 Specifically, the four lifting drive components 3 have the same structure. Taking one of the lifting drive components 3 as an example: the lifting drive component 3 includes a first cylinder 31, a second cylinder 32, and a lifting rod 33 arranged sequentially from bottom to top. The first cylinder 31, the second cylinder 32, and the lifting rod 33 are coaxially arranged. The bottom end of the second cylinder 32 is slidably disposed inside the first cylinder 31, and the bottom end of the lifting rod 33 is slidably disposed inside the second cylinder 32. The second cylinder 32 includes a first piston 321 located inside the first cylinder 31. The first piston 321 divides the internal space of the first cylinder 31 into a first chamber 311 and a second chamber 31 from bottom to top. 2. The first cylinder block 31 has a first oil port 313 and a second oil port 314. The first oil port 313 communicates with the first chamber 311, and the second oil port 314 communicates with the second chamber 312. The lifting rod 33 includes a second piston 331 located inside the second cylinder block 32. The second piston 331 divides the internal space of the second cylinder block 32 into a third chamber 322 and a fourth chamber 323 from bottom to top. The first piston 321 has a through hole 3211, and the third chamber 322 communicates with the first chamber 311 through the through hole 3211. The second cylinder block 32 has a third oil port 324, which communicates with the fourth chamber 323. Figure 1 In order to enable the top plate 4 to have a certain degree of micro-movement capability, a hemispherical flange 5 is provided at the connection between the lifting rod 33 and the top plate 4. The hemispherical flange 5 allows for a certain amount of adjustment at the connection between the lifting rod 33 and the top plate 4.

[0051] The two-stage lifting process of the top plate 4 is as follows: oil enters through the first oil port 313 and exits through the third oil port 324. The oil entering the first chamber 311 through the first oil port 313 passes through the through hole 3211 into the third chamber 322. The oil pushes the second piston 331 upward, thereby causing the lifting rod 33 to move the top plate 4 upward. This is the first stage of lifting of the top plate 4, during which the second cylinder 32 remains stationary. Afterward, oil stops exiting from the third oil port 324, and oil exits from the second oil port 314. This oil pushes the first piston 321 upward, thereby moving the second cylinder 32 upward. The lifting rod 33 then again moves the top plate 4 upward, completing the second stage of lifting of the top plate 4. Furthermore, by flexibly controlling the amount of oil entering and exiting through the first oil port 313, the distance the top plate 4 rises and falls can be controlled, thus locking the top plate 4 in place.

[0052] The secondary descent process of the top plate 4 is as follows: after the top plate 4 is fully raised, oil enters through the third oil port 324 and exits through the first oil port 313. The oil will drive the second piston 331 to move downward. This is the first stage of descent of the top plate 4. Then, oil enters through the second oil port 314 and continues to exit through the first oil port 313. The first piston 321 descends. This is the second stage of descent of the top plate 4.

[0053] Reference Figure 3 and Figure 4 A mounting housing 21 is fixed at the center of the top of the base plate 2. The front and top of the mounting housing 21 are open. A lifting member 22, which is a hydraulic cylinder, is provided on the inner bottom surface of the mounting housing 21. A first support mechanism 23 and a second support mechanism 24 are provided on the output end of the lifting member 22. The first support mechanism 23 supports the output end of the lifting member 22, and the second support mechanism 24 supports the top plate 4. The first support mechanism 23 and the second support mechanism 24 can move under the drive of the lifting member 22. Since the four lifting drive members 3 can drive the top plate 4 to rise and fall, the top plate 4 has two states: a high position and a low position. However, regardless of whether the top plate 4 is in a high position or a low position, the first support mechanism 23 can always support the output end of the lifting member 22, and the second support mechanism 24 can always support the top plate 4.

[0054] Reference Figure 4 and Figure 5 Specifically, the first support mechanism 23 includes a guide component 231 and a locking component 232. The guide component 231 is located on the output end of the lifting member 22 and is used to guide the up and down movement of the output end of the lifting member 22. The locking component 232 is located inside the mounting housing 21 and enables the top plate 4 to always lock and support the output end of the lifting member 22 through the guide component 231, whether the top plate 4 is in a high position or a low position. Thus, the second support mechanism 24 installed on the output end of the lifting member 22 locks and supports the top plate 4.

[0055] Reference Figure 5 More specifically, the guide assembly 231 includes a mounting base 2311, which is located on the output end of the lifting member 22. Four first support rods 2312 are movably provided on the side wall of the mounting base 2311. Each first support rod 2312 has a slider 2313 movably provided at its lower end. A groove 2314 is provided on the inner wall of the mounting housing 21. The slider 2313 is locked in the groove 2314 and can slide in the vertical direction. This design can guide the movement of the output end of the lifting member 22.

[0056] Reference Figure 4 and Figure 5 Two locking components 232 are provided, both located within the mounting housing 21. Each locking component 232 locks two sliders 2313. The two locking components 232 have identical and symmetrical structures. Taking the structure of the left locking component 232 as an example: (Combined with...) Figure 6The locking component 232 includes a mounting block 2321, which is fixed on the mounting housing 21. The mounting block 2321 has a sliding hole 2322 arranged in the vertical direction, and a sliding rod 2323 passes through the sliding hole 2322. The sliding rod 2323 can slide in the vertical direction.

[0057] Reference Figure 6 and Figure 7 Continuing with the example of the locking component 232 on the left: the top of the sliding rod 2323 is fixedly connected to two sliders 2313 via a connecting block 2324. Two first engaging parts 2325 are hinged to the side wall of the sliding rod 2323 near its bottom via two first hinge shafts 23251. The two first engaging parts 2325 are symmetrical to each other. Each first engaging part 2325 has a second engaging part 2326 hinged to its end away from the sliding rod 2323 via a second hinge shaft 23261. The two second engaging parts... The components 2326 are also symmetrical to each other. The end of each second engaging component 2326 away from the first engaging component 2325 is hinged to the mounting block 2321 via a third hinge shaft 23211. The axes of the first hinge shaft 23251, the second hinge shaft 23261, and the third hinge shaft 23211 are all parallel to each other. To prevent dead points from occurring during the movement of the locking assembly 232, the projections of the first hinge shaft 23251 and the third hinge shaft 23211 on the vertical plane are misaligned. In addition, a locking component 2327 is rotatably provided on the second engaging component 2326 on the left side. The locking component 2327 is used to restrict the rotation of the two second engaging components 2326, thereby restricting the movement of the sliding rod 2323.

[0058] Reference Figure 4 Corresponding to the high and low states of the top plate 4, the sliding rod 2323 also has a corresponding highest first limit position and a lowest second limit position, combined with Figure 6 , Figure 7 and Figure 8 , Figure 6 , Figure 7 and Figure 8This is a structural diagram showing the sliding rod 2323 in its first extreme position, intermediate position, and second extreme position, respectively. When the sliding rod 2323 is in the first extreme position, the two second engaging parts 2326 engage the two first engaging parts 2325, and the locking part 2327 is fitted onto the two second engaging parts 2326 to restrict their rotation, thus preventing the sliding rod 2323 from moving. When the sliding rod 2323 is in the second extreme position, the two second engaging parts 2326 engage the sliding rod 2323, and the locking part 2327 is still fitted onto the two second engaging parts 2326, again restricting their rotation, thus preventing the sliding rod 2323 from moving. This configuration ensures that the locking part 2327 always restricts the movement of the sliding rod 2323, regardless of whether the top plate 4 is in a high or low position. (Further details...) Figure 4 To prevent the sliding rod 2323 from hitting the inner bottom of the mounting housing 21 during its downward movement, the inner bottom of the mounting housing 21 is provided with a receiving hole 211 for each sliding rod 2323, and the receiving hole 211 penetrates the bottom plate 2 downward.

[0059] Reference Figure 9 The second support mechanism 24 includes a fixed base 241, which is located on the output end of the lifting member 22 and above the mounting base 2311. The fixed base 241 is hinged with six second support rods 242, which are evenly distributed along the circumference. Each second support rod 242 has a sliding member 243 at its upper end, which is a sliding ball. A sliding groove 244 is opened on the lower end surface of the top plate 4 corresponding to each second support rod 242. The sliding groove 244 extends towards the center of the top plate 4. The sliding member 243 is locked in the sliding groove 2314. When the top plate 4 is stationary, the output end of the lifting member 22 descends, which can drive the six sliding members 243 to slide towards the center of the top plate 4, thereby causing the six second support rods 242 to converge.

[0060] When the vehicle body 1 travels to an open area, since the possibility of heavy objects falling is not high, in order to reduce the space occupied by this application, the lifting component can be driven to move the fixed seat 241 downward, thereby causing the six second support rods 242 to converge.

[0061] Reference Figure 9 In order to enable the first support mechanism 23 to not only support the output end of the lifting member 22, but also support the second support mechanism 24, the top of the mounting base 2311 is provided with several load-bearing columns 23111, and the upper end of each load-bearing column 23111 is fixed to the bottom end of the fixed base 241.

[0062] The implementation principle of the RV pop-up device in this embodiment is as follows: driving four lifting drive components 3 can lift the top plate 4. After the top plate 4 reaches the high position, several second support rods 242 are in a converged state. Then, firstly, two locking components 2327 need to be rotated to release the locking components 2327 from locking the two second locking components 2326. Then, the lifting component 22 is driven. At this time, as the output end of the lifting component 22 rises, the fixed seat 241 moves up, several sliding components 243 slide towards the outer periphery of the top plate 4, and several second support rods 242 spread out to support the top plate 4. As the fixed seat 241 moves up, the mounting seat 2311 and several sliders 2313 also move up. The sliding rod 2323 changes from the second limit position to the first limit position. Then, the locking component 2327 is rotated to lock the two second locking components 2326, thus completing the locking of the top plate 4 in the high position.

[0063] The embodiments described herein are preferred embodiments of the present invention and are not intended to limit the scope of protection of the present invention. Therefore, all equivalent changes made in accordance with the structure, shape, and principle of the present invention should be covered within the scope of protection of the present invention.
