A caravan generally has an expansion mechanism to increase a usage space of the caravan. The existing motor home expansion mechanism is still in a closed state after expansion, and is inconvenient for users to fully contact with the outside when camping is leisure, so that the experience is poor.

Disclosure of Invention

The utility model aims to provide a carriage expanding mechanism which has the characteristic of being convenient for a user to fully contact with the outside.

The technical aim of the utility model is realized by the following technical scheme: the utility model provides a carriage expansion mechanism, includes the platform of articulated at the carriage afterbody, and the carriage afterbody is vertical to be provided with two pneumatic cylinders, and two pneumatic cylinders are located the both sides of carriage afterbody respectively, and the power take off end of pneumatic cylinder sets up downwards and articulates there is the transfer line, and the transfer line is kept away from the tip and the platform of pneumatic cylinder and articulates.

By adopting the technical scheme, the overturning of the platform is controlled through the driving action of the hydraulic cylinder, so that the platform is in a vertical state when the carriage does not need to be expanded, and is tightly attached to the tail part of the carriage, so that the carriage is in a closed state; when the carriage is expanded, the hydraulic cylinders on two sides of the tail of the carriage are utilized to push the transmission rods downwards, and the transmission rods drive the platform to rotate to a horizontal state when the carriage is in an open state, so that the carriage fully receives external light and air, and meanwhile, a user can rest on the platform conveniently and fully contact the external environment.

Preferably, the top of the carriage is provided with a telescopic sunshade mechanism.

By adopting the technical scheme, when the platform is used, the sun-shading effect can be achieved on the platform by extending the sun-shading mechanism.

Preferably, the sunshade mechanism comprises a motor, a chain and a sunshade frame, wherein the motor, the chain and the sunshade frame are arranged at the top of the carriage, the motor is connected with a chain wheel meshed with the chain, the chain is connected with the sunshade frame, the top of the carriage is provided with a track along the telescopic direction of the sunshade frame, and the sunshade frame is glidingly connected in the track.

By adopting the technical scheme, the motor drives the sunshade frame to slide in the track by utilizing the chain wheel and the chain, so that the telescopic function of the sunshade mechanism is realized.

Preferably, the sunshade frame is provided with a solar panel.

By adopting the technical scheme, when the sunshade mechanism stretches out, the solar panel can be utilized to absorb solar energy, and energy is provided for the vehicle.

In summary, the utility model has the following beneficial effects:

1. the user can fully contact the external environment of the carriage, so that better leisure experience is achieved;

2. the ventilation and lighting effects in the carriage can be effectively improved after the carriage is expanded;

3. the stretched sunshade mechanism can absorb solar energy while sunshade, and provides additional energy for the interior of the vehicle.

In the figure, 1, a carriage; 2. a platform; 3. a hydraulic cylinder; 4. a transmission rod; 51. a motor; 52. a chain; 53. a sunshade frame; 54. a sprocket; 55. a track; 56. a solar panel.

Detailed Description

The present utility model will be described in further detail with reference to the accompanying drawings.

The present embodiment is only for explanation of the present utility model and is not to be construed as limiting the present utility model, and modifications to the present embodiment, which may not creatively contribute to the present utility model as required by those skilled in the art after reading the present specification, are all protected by patent laws within the scope of claims of the present utility model.

Examples: as shown in fig. 1 and 2, a hydraulic cylinder 3 is installed at the tail of a carriage 1, and the number of the hydraulic cylinders 3 is two. The two hydraulic cylinders 3 are vertically connected to two sides of the tail of the carriage 1 respectively. The bottom of the tail part of the carriage 1 is hinged with a platform 2, and the platform 2 is plate-shaped and can rotate along a vertical plane. The power output end of the hydraulic cylinder 3 is vertically downwards arranged, the power output end is hinged with a transmission rod 4, and one end of the transmission rod 4 away from the hydraulic cylinder 3 is hinged with the side face of the platform 2. A sunshade mechanism which can be telescopic out of the tail of the carriage 1 is arranged at the top of the carriage 1.

As shown in fig. 3 and 4, the sunshade mechanism includes a horizontally installed rail 55, a sunshade frame 53 is slidingly connected in the rail 55, and a solar panel 56 is installed on the surface of the sunshade frame 53. A chain 52 is mounted on the roof of the vehicle cabin 1 below the sunshade 53. The chain 52 is installed along the sliding direction of the sunshade 53 for driving the sunshade 53 to slide. A motor 51 is arranged below the sunshade 53, a chain wheel 54 is connected to the motor 51, and the chain wheel 54 is meshed with the chain 52.
