Description

Technical Field

[0001] The utility model relates to the technical field of recreational vehicles, in particular to a roof support and protection structure of a recreational vehicle. Background Art

[0002] RV roofs are usually equipped with various devices, such as solar panels, air conditioners, skylights, and cameras.

[0003] If the RV roof does not have a corresponding supporting and protective structure, it will face the following problems: when passing by low trees, branches will scratch or even damage the equipment, causing unnecessary property losses. If the RV roof has a corresponding supporting and protective structure, it will face the following problems: destroying the overall lines of the body, making the body look less smooth; increasing the vehicle's wind resistance coefficient, causing the vehicle to be subject to greater wind resistance when driving at high speeds, thereby increasing fuel consumption and noise. Especially when driving at high speeds, wind noise may become more obvious, affecting driving comfort.

[0004] In response to the above problems, some conventional RVs are not designed with roof protection structures, while other RVs are only designed with fixed protection structures. Both situations cannot effectively meet the driving needs of drivers in different driving scenarios. Utility Model Content

[0008] By adopting the above technical solution, when the support frame is not needed, the linear drive extends and drives the support frame down, thereby reducing the impact on the movement of the RV; when the support frame is needed, the linear drive shortens, and the transmission rod pulls the support frame to make it vertical to protect the roof equipment. The driver can choose whether to use the support frame according to the driving environment, thereby meeting the driver's driving needs in different driving environments.

[0009] Optionally, a receiving groove for receiving the lowered support frame is provided at the edge of the roof.

[0010] By adopting the above technical solution, the accommodating groove can be used to accommodate the support frame when the support frame is not in use, so as to reduce wind resistance.

[0011] Optionally, the bottom of the accommodating groove is arranged to be inclined downward in a direction away from the center of the roof.

[0012] By adopting the technical solution, it is convenient to discharge water and other debris from the roof of the vehicle.

[0013] Optionally, a supporting block for supporting the support frame is arranged in the accommodating groove.

[0014] By adopting the above technical solution, the supporting block supports the supporting frame, so that a gap is left between the supporting frame and the bottom of the receiving groove to facilitate the discharge of water and other debris.

[0015] Optionally, a torsion spring for elastically driving the support frame to rotate into the accommodating groove is provided at the connection point between the support frame and the roof.

[0016] By adopting the above technical solution, the torsion spring is used in conjunction with the linear drive, so that the support frame can be easily accommodated in the accommodating groove.

[0017] Optionally, a rotating shaft is fixedly connected to the support frame, a fixing seat is fixedly connected to the roof, a accommodating cavity is arranged in the fixing seat, a stopper one is fixedly connected to the rotating shaft, a stopper two is fixedly connected to the inner wall of the accommodating cavity, the rotating shaft is rotatably arranged in the accommodating cavity, a torsion spring is sleeved on the rotating shaft, one leg of the torsion spring abuts against the stopper one, and the other leg of the torsion spring abuts against the stopper two.

[0018] By adopting the above technical solution, the torsion spring is accommodated in the fixing seat to reduce the adverse effects of the external environment on the torsion spring.

[0019] Optionally, the linear drive is an electric push rod.

[0020] By adopting the above technical solution, the electric push rod is easy to use and install to meet usage requirements.

[0021] Optionally, the support frame is arch-shaped and has a hollow hole in the middle.

[0022] By adopting the above technical solution, the overall structural strength is enhanced and the overall weight is reduced.

[0023] In summary, the utility model includes at least one of the following beneficial technical effects:

[0024] When the support frame is not needed, the linear drive extends and drives the support frame down, thereby reducing the impact on the movement of the RV; when the support frame is needed, the linear drive shortens, and the transmission rod pulls the support frame to make it vertical to protect the roof equipment. The driver can choose whether to use the support frame according to the driving environment, thereby meeting the driver's driving needs in different driving environments;

[0025] The receiving slot can be used to receive the support frame when the support frame is not in use, so as to reduce wind resistance;

[0026] The torsion spring is used in conjunction with the linear drive to facilitate the support frame to be stored in the receiving groove. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0032] The following is combined with Figure 1 -Attached Figure 4 The utility model is described in further detail.

[0033] The utility model embodiment discloses a RV roof support and protection structure. Figure 1 and Figure 2 The RV roof support and protection structure is installed on the roof of the vehicle body 1, and includes a support frame 2 for protecting the roof, a fixing seat 3 for installing the support frame 2, and a rotation driving mechanism 4 for driving the support frame 2 to rotate.

[0034] Reference Figure 1 and Figure 2 A receiving groove 10 for receiving the lowered support frame 2 is provided near the edge of the roof of the vehicle body 1. When the support frame 2 is received in the receiving groove 10, the wind resistance is effectively reduced. The fixing seat 3 is welded in the receiving groove 10. The bottom of the receiving groove 10 is tilted downward from the side close to the center of the roof to the side away from the center of the roof and is arranged in an arc-shaped transition to facilitate the drainage of water and other debris. Two supporting blocks 11 for supporting the lowered support frame 2 are also welded in the receiving groove 10. Through the design of the supporting blocks 11, a gap is left between the support frame 2 and the bottom of the receiving groove 10 to facilitate the drainage of water and other debris.

[0035] Reference Figure 3 and Figure 4The support frame 2 is in the shape of an arch, with an arc transition and a hollow hole 20 in the middle to enhance strength and reduce weight. A rotating shaft 21 is welded at both ends of the support frame 2, and a stopper 22 is welded on the peripheral wall of the rotating shaft 21. A receiving cavity 30 is provided in the fixing seat 3, and a stopper 2 31 is welded on the inner wall of the receiving cavity 30. The rotating shaft 21 is rotatably arranged in the receiving cavity 30, and a torsion spring 32 is sleeved on the rotating shaft 21. One leg of the torsion spring 32 is mounted on the stopper 22, and the other leg of the torsion spring 32 is mounted on the stopper 2 31. The torsion spring 32 has a tendency to drive the support frame 2 to rotate away from the center of the roof.

[0036] Reference Figure 2 and Figure 3 The rotation drive mechanism 4 includes an electric push rod 40 ( Figure 2 The electric push rod 40 is located inside the roof, thereby reducing the impact of adverse external environment on it. The electric push rod 40 is controlled by the operation panel located in the cab. The extension direction of the push rod of the electric push rod 40 is perpendicular to the length direction of the support frame 2. The electric push rod 40 is located on the side of the support frame 2 close to the center of the roof. In other embodiments, common mechanical structures such as cylinders can also be used as linear actuators. A transmission rod 41 is hinged at the push rod end of the electric push rod 40, and the top end of the transmission rod 41 is hinged on the side wall of the support frame 2.

[0037] The implementation principle of the RV roof support protection structure of the utility model embodiment is: when the support frame 2 is not needed, the electric push rod 40 is extended, and under the joint action of the torsion spring 32 and the transmission rod 41, the support frame 2 is lowered into the receiving groove 10, thereby reducing the impact on the RV during travel; when the support frame 2 is needed, the electric push rod 40 is shortened, and the transmission rod 41 pulls the support frame 2 to make the support frame 2 present a vertical state to protect the roof equipment. The driver can choose whether to use the support frame 2 according to the driving environment, thereby meeting the driver's driving needs in different driving environments.

[0038] The above are all preferred embodiments of the present utility model, and are not intended to limit the protection scope of the present utility model.
