Description

Technical Field

[0001] This utility model belongs to the field of RV technology, and in particular relates to a flipping structure for RVs and an RV. Background Technology

[0002] As an ideal vehicle for modern mobile living, RVs perfectly integrate the dual functions of transportation and living space, providing comprehensive solutions for users' travel, camping, and long-term stays. Their interiors typically include bedrooms, kitchens, bathrooms, and other living areas, along with modern amenities such as air conditioning and televisions, to provide users with a comfortable and convenient travel experience. However, within the limited space of the RV, achieving efficient space utilization is key to improving the comfort of RV use.

[0003] In contemporary RV design, multifunctional furniture systems (such as folding tables, lift-up beds, and convertible sofas) have become key technologies for space optimization. Among these, flip-up panel structures are widely used in these functional furniture pieces due to their flexibility and versatility. Currently, flip-up panel drive technologies in the industry are mainly divided into two categories: traditional manual operation and mechanical drive based on rotary drive components. However, both solutions have certain drawbacks in practical applications: for larger and heavier flip-up panels, manual operation not only requires users to expend a lot of physical strength, but also often requires multiple people to cooperate during angle adjustments, making the operation process cumbersome and posing potential safety risks. Mechanical solutions using rotary drive components, due to their rigid connection to the panel, not only require the rotary drive component to output a large driving force, but are also prone to structural damage at the connection points during long-term use, seriously affecting the service life and operational reliability of the flip-up panel.

[0004] Therefore, there is an urgent need for a tilting structure and a motorhome to solve the above problems. Utility Model Content

[0005] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a flipping structure for motorhomes and a motorhome, which reduces the overall manufacturing cost and failure rate of the flipping structure, reduces the possibility of structural damage at the connection between the plate and the push wheel, and improves the efficiency of plate rotation, the service life of the plate and the operational reliability.

[0006] To achieve this objective, the present invention adopts the following technical solution:

[0007] On the one hand, a tilting structure for motorhomes is provided, including:

[0008] support;

[0009] The plate is rotatably mounted on the bracket about a first direction. The plate has a storage position that is embedded in the bracket and a use position that is perpendicular to the bracket. In the use position, the plate extends along a second direction that is perpendicular to the first direction.

[0010] The push wheel is movably mounted on the bracket in the second direction, driving the push wheel to move in the second direction. The push wheel can contact and roll with the plate, pushing the plate to rotate.

[0011] Optionally, a connector is provided on the side of the plate facing the push wheel. The connector includes a first surface and a second surface arranged at an angle. The first surface is parallel to the plate, and the second surface extends from the first surface to the plate. In the use position, the push wheel contacts the first surface. When the push wheel is driven to move, the push wheel can roll between the plate and the first surface via the second surface.

[0012] Optionally, the connector is provided with a connecting groove that extends from the second surface to the first surface, and the push wheel can be embedded in the connecting groove and roll in cooperation with the groove wall.

[0013] Alternatively, the drive wheel is provided with a connecting groove extending circumferentially therein, and the connector can be embedded in the connecting groove and roll in cooperation with the groove wall.

[0014] Optionally, the tilting structure for the RV also includes a linear drive unit mounted on the bracket, the output end of which is connected to a push wheel to drive the push wheel to reciprocate along a second direction.

[0015] Optionally, the linear drive includes a housing, a drive unit, and an output shaft. The housing is mounted on a bracket, the output shaft is movably mounted on the housing along a second direction and connected to a push wheel, and the drive unit is mounted on the housing and connected to the output shaft for driving the output shaft to move the push wheel along the second direction.

[0016] Optionally, the tilting structure for the RV also includes a control unit mounted on the bracket, which is electrically connected to the linear drive and is used to control the opening and closing of the linear drive.

[0017] Optionally, the control unit includes a control switch and a controller. The controller is electrically connected to the linear drive and is used to control the opening and closing of the linear drive. The control switch is communicatively connected to the controller and is used to control the working state of the controller.

[0018] Optionally, multiple push wheels and linear drive components are provided, with multiple push wheels arranged at intervals along the first direction, and multiple linear drive components corresponding one-to-one with multiple push wheels.

[0019] Optionally, the tilting structure for the RV also includes a rotating component, which includes a first rotating part and a second rotating part that are rotatably connected. The first rotating part is connected to the bracket, and the second rotating part is connected to the plate.

[0020] On the other hand, a motorhome is provided, including a passenger compartment and the aforementioned tilting structure for the motorhome, wherein the tilting structure for the motorhome is disposed inside the passenger compartment.

[0021] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0022] This invention provides a flipping structure and a motorhome for use in motorhomes. When the drive wheel moves in a second direction, it contacts and pushes the panel to rotate, allowing the panel to switch between a storage position and a usage position, thus achieving the flipping of the panel. Compared with the prior art of directly driving the panel to rotate, converting the linear motion of the drive wheel into the rotational motion of the panel not only consumes less energy, helping to reduce the cost of driving the panel to rotate and improve the efficiency of the panel rotation, but also helps to reduce the number of parts used to drive the panel to rotate, significantly reducing the overall manufacturing cost and failure rate of the flipping structure. While the drive wheel pushes against the panel, it can also roll relative to the panel. On the one hand, this significantly reduces the friction between the drive wheel and the panel, helping to further reduce the energy consumption of driving the panel to rotate and improve the efficiency of the panel rotation; on the other hand, the flexible connection between the panel and the drive wheel helps to reduce the noise generated by the panel rotation and the vibration amplitude of the panel, reducing the possibility of structural damage at the connection between the panel and the drive wheel, and improving the service life and operational reliability of the panel.

[0031] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0032] Example 1

[0033] like Figures 1 to 4 As shown, this embodiment provides a flipping structure for RVs, which reduces the overall manufacturing cost and failure rate of the flipping structure, reduces the possibility of structural damage at the connection between the plate 2 and the push wheel 3, and improves the rotation efficiency of the plate 2, the service life of the plate 2, and the operational reliability.

[0034] See Figure 2 and Figure 3 The tilting structure for the RV includes a support frame 1, a plate 2, and a push wheel 3. The plate 2 rotates in a first direction ( Figure 2 The plate 2 is rotatably mounted on the bracket 1 in the X direction. The plate 2 has a storage position where it is embedded in the bracket 1 and a usage position perpendicular to the bracket 1. In the usage position, the plate 2 is rotatably mounted on the bracket 1 in the second direction (X direction). Figure 2 The first direction extends in the Y direction, and the second direction is perpendicular to the first direction; the push wheel 3 is movably mounted on the bracket 1 along the second direction, driving the push wheel 3 to move along the second direction, the push wheel 3 can contact and roll with the plate 2, and the push wheel 3 pushes the plate 2 to rotate.

[0035] The RV-style flipping structure provided in this embodiment allows the push wheel 3 to contact and push the plate 2 to rotate when the push wheel 3 moves in the second direction, enabling the plate 2 to switch between a storage position and a usage position, thus achieving the flipping of the plate 2. Compared with the prior art of directly driving the plate 2 to rotate, converting the linear motion of the push wheel 3 into the rotational motion of the plate 2 not only consumes less energy, helping to reduce the cost of driving the plate 2 to rotate and improve the efficiency of the plate 2 rotation, but also helps to reduce the number of parts used to drive the plate 2 to rotate, significantly reducing the overall manufacturing cost and failure rate of the flipping structure. While pushing against the plate 2, the push wheel 3 can also roll relative to the plate 2. On the one hand, this significantly reduces the friction between the push wheel 3 and the plate 2, helping to further reduce the energy consumption of driving the plate 2 to rotate and improve the efficiency of the plate 2 rotation; on the other hand, the flexible connection between the plate 2 and the push wheel 3 helps to reduce the noise generated by the rotation of the plate 2 and the vibration amplitude of the plate 2, reducing the possibility of structural damage at the connection between the plate 2 and the push wheel 3, and improving the service life and operational reliability of the plate 2.

[0036] Specifically, see Figure 3 and Figure 4 The bracket 1 is provided with a mounting groove 11. When the plate 2 is in the storage position, it is located in the mounting groove 11 and the surface of the plate 2 is flush with the surface of the bracket 1 to ensure the flatness of the surface of the bracket 1 when it is in the storage position and to prevent the plate 2 from bumping into the user.

[0037] Optionally, see Figure 2 and Figure 3 A connecting member 4 is provided on the side of the plate 2 facing the push wheel 3. The connecting member 4 includes a first surface 41 and a second surface 42 arranged at an angle. The first surface 41 is parallel to the plate 2, and the second surface 42 extends from the first surface 41 to the plate 2. In the use position, the push wheel 3 is in contact with the first surface 41. When the push wheel 3 is driven to move, it can roll between the plate 2 and the first surface 41 via the second surface 42. As the push wheel 3 pushes the plate 2 to rotate from the storage position to the use position, the push wheel 3 will sequentially push different parts of the plate 2 along the direction close to the rotation axis of the plate 2, so that the energy consumption for driving the push wheel 3 to move gradually increases. The connection 4 increases the distance between the push wheel 3 and the plate 2 as the push wheel 3 rolls from the second surface 42 to the first surface 41, which helps to reduce the distance the push wheel 3 needs to move. Moreover, it allows the plate 2 and the push wheel 3 to maintain stable contact in the usage position without increasing the thickness of the plate 2, increasing the size of the push wheel 3, or reducing the distance between the push wheel 3 and the rotation axis of the plate 2. This helps to reduce the energy consumption of driving the plate 2 to rotate and the production cost of the plate 2 and the push wheel 3.

[0038] Specifically, see Figure 2 and Figure 3 When the push wheel 3 is driven to move in the second direction toward the plate 2, the push wheel 3 first contacts the plate 2, and then rolls from the second surface 42 to the first surface 41, and the plate 2 switches from the storage position to the use position; in the use position, the push wheel 3 contacts the first surface 41; when the push wheel 3 is driven to move in the second direction away from the plate 2, the push wheel 3 rolls from the first surface 41 to the plate 2 via the second surface 42, and the plate 2 switches from the use position to the storage position.

[0039] For example, the cross-sectional shape of the connector 4 is trapezoidal, the first surface 41 is the top surface of the trapezoid, the second surface 42 is the inclined surface of the trapezoid, and the surface of the plate 2 is the bottom surface of the trapezoid.

[0040] For example, the greater the distance between the push wheel 3 and the rotation axis of the plate 2, the less energy the push wheel 3 consumes to rotate the plate 2. In this embodiment, the push wheel 3 preferably pushes the middle position of the plate 2.

[0041] In this embodiment, the connector 4 is provided with a connecting groove that extends from the second surface 42 to the first surface 41. The push wheel 3 can be embedded in the connecting groove and roll in cooperation with the groove wall. This arrangement allows the groove wall to restrict the movement direction of the push wheel 3 during its rolling motion, enabling the push wheel 3 to move stably between the first surface 41 and the second surface 42, thus improving the stability of the push wheel 3 when it pushes against the rotating plate 2.

[0042] In other embodiments, the push wheel 3 is provided with a connecting groove extending circumferentially therein, and the connecting member 4 can be embedded in the connecting groove and roll in cooperation with the groove wall. This arrangement allows the groove wall of the connecting groove to contact the connecting member 4 during the rolling of the push wheel 3, thereby limiting the direction of movement of the push wheel 3 and helping to improve the stability of the push wheel 3 when it pushes against the rotating plate 2.

[0043] Optionally, see Figure 2 and Figure 3 The RV tilting structure also includes a linear drive 5 mounted on the bracket 1. The output end of the linear drive 5 is connected to the push wheel 3, which drives the push wheel 3 to reciprocate along a second direction. By utilizing the linear drive 5, the position of the plate 2 can be switched, and the position of the push wheel 3 can be controlled, which helps to precisely control the rotation angle of the plate 2 and improve the stability of the plate 2's rotation.

[0044] In this embodiment, see Figure 2 and Figure 3The linear drive 5 includes a housing 51, a drive unit 52, and an output shaft 53. The housing 51 is mounted on the bracket 1. The output shaft 53 is movably mounted on the housing 51 along a second direction and connected to the push wheel 3. The drive unit 52 is mounted on the housing 51 and connected to the output shaft 53, and is used to drive the output shaft 53 to move the push wheel 3 along the second direction. By controlling the distance the output shaft 53 moves, the drive unit 52 can precisely control the rotation angle of the plate 2, which helps to ensure the rotation accuracy of the plate 2.

[0045] For example, the linear drive 5 is an electric push rod, the housing 51 is the outer shell of the electric push rod, the drive part 52 is the drive motor of the electric push rod, and the output shaft 53 is the push rod of the electric push rod. The drive motor is connected to the push rod through transmission components such as reduction gears, screws and nuts to convert the rotational motion of the drive motor into the linear motion of the push rod. The setting of the transmission components also helps to ensure the accuracy and stability of the movement of the drive wheel 3, and makes the linear drive 5 suitable for the rotation of the plate 2 with a large size and a large weight.

[0046] The output direction of the drive motor is adjustable, allowing the push wheel 3 to reciprocate along the second direction. Specifically, when the plate 2 switches from the storage position to the use position, the output of the drive motor rotates forward, and the push rod drives the push wheel 3 to move closer to the plate 2 along the second direction. When the plate 2 switches from the use position to the storage position, the output of the drive motor rotates in reverse, and the push rod drives the push wheel 3 to move away from the plate 2 along the second direction.

[0047] In other embodiments, the linear drive 5 is a hydraulic rod, the piston rod of which is connected to the push wheel 3 to drive the push wheel 3 to move in the second direction.

[0048] In other embodiments, the linear drive 5 is a telescopic rod, one end of which is connected to the push wheel 3.

[0049] In this embodiment, see Figure 2 and Figure 3 The RV flipping structure also includes a control unit 6 installed on the bracket 1. The control unit 6 is electrically connected to the linear drive 5 and is used to control the opening and closing of the linear drive 5 to realize the automatic switching of the position of the plate 2, thereby improving the automation of driving the plate 2 to rotate.

[0050] Specifically, see Figure 2 and Figure 3The control unit 6 includes a control switch 61 and a controller 62. The controller 62 is electrically connected to the linear drive 5 and is used to control the opening and closing of the linear drive 5. The control switch 61 is communicatively connected to the controller 62 and is used to control the working state of the controller 62. This configuration allows the user to control the rotation of the plate 2 by standing at the control switch 61 when the bracket 1 is large, without needing to stand on the plate 2 itself, greatly improving ease of use. Furthermore, the operation is convenient and quick, enhancing the user experience.

[0051] For example, the control switch 61 is large in size and has an anti-slip function to facilitate one-handed operation. The controller 62 can control the direction and distance of movement of the push wheel 3 in the second direction by controlling the opening and closing of the linear drive 5, which helps to improve the automation of the rotation of the plate 2.

[0052] For example, the controller 62 is equipped with a smart chip to prevent short circuits or overloads. Specifically, when the linear drive 5 malfunctions, the smart chip can automatically cut off the power supply to the linear drive 5 to ensure the safety of the tilting structure used in the RV during operation.

[0053] In this embodiment, see Figure 2 and Figure 3 Multiple push wheels 3 and linear drive components 5 are provided. The multiple push wheels 3 are arranged at intervals along the first direction, and the multiple linear drive components 5 correspond one-to-one with the multiple push wheels 3. The arrangement of multiple push wheels 3 allows all parts of the plate 2 to be pushed along the first direction, and the arrangement of multiple linear drive components 5 allows multiple push wheels 3 to push the plate 2 to rotate simultaneously, which helps to improve the rotational stability of the plate 2.

[0054] For example, see Figure 2 and Figure 3 There are two push wheels 3 and two linear drive components 5. The two push wheels 3 are located at both ends of the plate 2 along the first direction and are arranged symmetrically about the plate 2.

[0055] Optionally, see Figure 3 The tilting structure for the RV also includes a rotating component 7, which includes a first rotating part and a second rotating part that are rotatably connected. The first rotating part is connected to the bracket 1, and the second rotating part is connected to the plate 2, so that the plate 2 can be rotatably connected to the bracket 1 through the first rotating part and the second rotating part.

[0056] For example, the rotating element 7 is a hinge.

[0057] Example 2

[0058] This embodiment provides a motorhome, including a cabin and a tilting structure for the motorhome as described in Embodiment 1. The tilting structure for the motorhome is installed inside the cabin to improve the utilization rate of the cabin space.

[0059] For example, the support 1 is the table leg of the table, and the plate 2 is the tabletop of the table; the support 1 is the frame of the shelf, and the plate 2 is the shelf of the shelf.

[0060] The above description is only a specific embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Those skilled in the art should understand that any changes or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in the present utility model fall within the protection and disclosure scope of the present utility model.
