Embodiment 2

2018101648 03 Nov 2018

This embodiment provides a recreational vehicle with a multi-functional flipping device of another configuration.

As shown in Fig.7 and Fig.fO, a forward and backward double-flipping type traction type recreational vehicle includes a compartment 1, and 5 compartment cover 2 at the top of the compartment, and the compartment cover 2 includes an upper cover 21 and an inner cover 31.

As shown in Fig. 10 and Fig. 11, the tail edge of the inner cover 31 is hinged to the front wall of the compartment 1, and the inner cover 31 can be freely flipped forward. As shown in Fig. 11, in the present embodiment, the 10 tail portion of the inner cover 31 is provided with a hinge plate 14, the top of the hinge plate 14 is fixedly connected with the tail portion of the inner cover 31, and the bottom of the hinge plate 14 is hinged to the inner side of the frant wall of the compartment 1 by means of the hinge shaft 15, such that the height of the flipping axis of the inner cover 31 is lower than the height of the 15 top of the front wall of the compartment, thereby raising the height of the inner cover 31 after being flipped up, and reducing the height of the flipping axis of the inner cover 31, thereby ensuring the inner cover 31 will not be interfered by the front wall of the compartment 1 when it is flipped up, and at the same time, ensures that the inner cover 31 is entirely located inside the 20 compartment 1 when it is closed.

As shown in Fig. 10 and Fig. 12, the upper cover adopts a backwardflipping structure, the tail edge of the upper cover 21 is hinged to the tail wall of the compartment 1, and the upper cover 21 is freely flipped backward. As shown in Fig. 12, in the present embodiment, the tail portion of the upper 25 cover 21 is provided with a hinge plate 14, and the top of the hinge plate 14 is hinged to the tail portion of the upper cover 21 by means of the hinge shaft 15, the bottom of the hinge plate 14 is fixedly connected with the tail wall of

2018101648 03 Nov 2018 the compartment 1. The height of the hinge shaft 15 is higher than the height of the top of the tail wall of the compartment 1, thereby raising the height of the flipping axis of the upper cover, so that the height of the flipping axis of the upper cover 21 is higher than the flipping axis of the inner cover 31, assuring the upper cover 21 covering the top of the inner cover 31 after the inner cover 31 and the upper cover 21 are closed.

As shown in Fig. 11 and Fig. 12, in the present embodiment, the flipping of the inner cover 31 and the upper cover 21 is realized by an electric flipping device, and the electric flipping device further includes an electric linear 10 actuator 4 and a link mechanism 5.

The bottom of the electric linear actuator 4 is hinged to the frame at the bottom of the compartment, the telescopic rod 8 of the electric linear actuator 4 is hinged to the middle of the rotating rod 6; one end of the rotating rod 6 is hinged to the inner wall of the compartment 1, and the other end of the 15 rotating rod 6 is connected with one end of the connecting rod 7, and the other end of the connecting rod 7 is hinged to the flipping cover. According to Fig.l 1 and Fig. 12, when the telescopic rod 8 of the electric linear actuator 4 is linearly moved up and down, the flipped cover body can be flipped 180° around the flipping axis by the rotation of the rotating rod 6 and the 20 connecting rod 7, thereby achieving opening and closing the cover body to form a flipping action.

Although the electronically controlled driving device provided by the present embodiment can achieve the flipping effect, since the rotating rod 6 and the connecting rod 7 are limited by space, the length thereof cannot be too 25 long, so in order to achieve smooth rotation under load, it is necessary to increase the power of the electric linear actuator, otherwise it is easy to burn the electric linear actuator. The increase in the power of the electric linear

2018101648 03 Nov 2018 actuator means an increase in the power consumption and an increase in the installation space of the electric linear actuator. To solve such a technical problem, as shown in Fig. 8 and Fig. 9, a gas spring 9 is provided respectively on the inner cover 31 and the lateral portion of the upper cover 21. In 5 combination with Fig. 13, in the present embodiment, the width of the inner cover 31 is smaller than the width of the compartment 1, a longitudinal slot 16 is formed on the front wall of the lateral portion of the inner cover corresponding to the front wall of the compartment. The longitudinal slot 16 has a top opening that is open at the top of the front wall. As shown in Fig. 13 10 and Fig. 11, one end of the gas spring 9 on the lateral portion of the inner cover is hinged to the lateral portion of the inner cover, and the other end of the gas spring is hinged to the groove wall of the slot 16. When the inner cover 31 is turned over, the gas spring 9 can swing freely forward and backward inside the slot 16 .

When the upper cover 21 is being turned over, the gas spring 9 is swinging, and extending and contracting at the lateral portion of the compartment.

After the gas spring 9 is provided, when the inner cover 31 and the upper cover 21 are turned over, the gas spring 9 can serve as an auxiliary assisting force, effectively reducing the load of the electric linear actuator, and preventing the electric linear actuator from being burnt due to excessive load.

As shown in Fig. 11, a slot blocking plate 17 is further included. The width and height of the slot blocking plate 17 are consistent with the width and height of the slot 16, and the bottom of the slot blocking plate 17 is hinged to the external side of the bottom of the slot. A pulling rod 18 is

2018101648 03 Nov 2018 disposed between the slot blocking plate 17 and the gas spring 9 on the lateral portion of the inner cover. The two ends of the pulling rod 18 are respectively hinged to the slot blocking plate and the gas spring. When the inner cover 31 is turned forward, with the swing of the gas spring 9, the slot blocking plate 5 17 rotates to open the slot 16 and the gas spring 9 protrudes from the inside of the slot 16. When the inner cover 31 is closed, the gas spring 9 swings toward inside the compartment, and at the same time, pulling the slot blocking plate 17 to block the slot.
