Description

Technical Field

[0001] The utility model mainly relates to the technical field of pickup truck expansion, and specifically relates to a pickup truck compartment expansion device. Background Art

[0002] Currently, the more economical RVs in China are mainly modified from pickup trucks, and these pickup RVs come in two types: those with a raised roof and those without. Pickup RVs with a raised roof are inconvenient to fix at a fixed height and offer good privacy, but they cannot pass through height-restricted roads. Their high center of gravity not only increases wind resistance and fuel consumption at high speeds, but also creates high centrifugal force when cornering, making them prone to rollovers and unsafe. Furthermore, these pickup RVs with a raised roof have a limited purpose and are not cost-effective. Pickup RVs with a raised roof expand the interior space by raising and lowering the roof. When driving, the roof is lowered to lower the center of gravity, reduce wind resistance, lower fuel consumption, and improve cornering stability and driving safety. When parking or using the RV function, the roof is raised to expand the interior space and enhance comfort.

[0003] Existing pickup-top RVs primarily consist of a pickup truck and a box. The truck includes a front and cargo box, while the box consists of a lower box and an upper box. The lower box is fixed to the cargo box, while the upper box is connected to the lower box via a lifting mechanism. A waterproof sheet is connected between the upper and lower boxes. When the upper box is raised, the sheet unfolds to enclose the area between the upper and lower boxes. When the upper box is lowered, the soft sheet retracts. While these pickup-top RVs are easy to raise and lower, the space they can expand is limited, making them inadequate for multiple passengers. Utility Model Content

[0029] In order to make the purpose, technical solutions and advantages of the present invention more clear, the embodiments of the present invention will be further described in detail below with reference to the accompanying drawings.

[0030] The utility model provides a pickup truck compartment expansion device, comprising a compartment cover 1 provided on the rear compartment of the pickup truck, the compartment cover being connected to a first expansion mechanism, the first expansion mechanism being used to drive the compartment cover to move up and down, thereby opening / closing the rear compartment 2 of the pickup truck;

[0031] An upper expandable bed board 3 and a lower expandable bed board 4 are provided between the rear compartment and the compartment cover of the pickup truck;

[0032] The upper expandable bed board is connected to a fifth expansion mechanism, and the fifth expansion mechanism is used to drive the upper expandable bed board to move up and down;

[0033] The lower expandable bed board is connected to a third expansion mechanism, and the third expansion mechanism is used to drive the lower expandable bed board to move up and down to adjust the distance between the lower expandable bed board and the upper expandable bed board;

[0034] When the compartment cover, the upper expandable bed board and the lower expandable bed board are moved to a preset height by the lifting mechanism, the expandable bed board is extended in length to both sides;

[0035] When the trunk lid is lowered to close the rear compartment of the pickup truck, the upper expandable bed board and the lower expandable bed board are moved simultaneously and accommodated in the closed rear compartment of the pickup truck.

[0036] The fifth expansion mechanism is a second lifting push rod 5, one end of which is connected to the rear compartment 2 of the pickup truck, and the other end is connected to the upper expandable bed plate 3;

[0037] The first expansion mechanism is a first lifting push rod 6, one end of which is connected to the upper expandable bed board 3, and the other end is connected to the compartment cover 1; of course, the first lifting push rod connected to the upper expandable bed board can also be connected to the rear compartment of a pickup truck.

[0038] A positioning rail 7 is installed between the upper expandable bed and the pickup truck's rear compartment. This rail ensures a straight line during lowering, preventing the bed frame from tilting. The first lifting rod is located within the movable block of the positioning rail, effectively saving space.

[0039] A tent is connected between the compartment cover and the vehicle body so as to close the rear compartment of the pickup truck when the compartment cover is lowered or raised.

[0040] All upper expandable bed boards 3 are arranged on the bed frame, the bed frame is connected to the fifth expansion mechanism to drive the bed frame to move up and down, and the box cover is connected to the bed frame through the first expansion mechanism to drive the box cover to move up and down.

[0041] The third expansion mechanism includes a lifting motor 8 arranged at the lower part of the upper expandable bed board 3. The lifting motor 8 can be in a pushing form or a reel form. The lifting motor is connected to the lower expandable bed board 4 through a rope and a pulley 9. A support frame 11 is provided in the rear compartment of the pickup truck. A support beam 12 is provided on the support frame 11. When the lifting motor drives the lower expandable bed board to a preset position through the rope, the support beam contacts the lower expandable bed board to support the lower expandable bed board.

[0049] A sealed rainproof cloth is provided between the box cover and the rear compartment, the upper end of the rainproof cloth is connected to the box cover, and the lower end is connected to the upper ends of the front and rear baffles and left and right side panels of the rear compartment. The upper end of the rainproof cloth at the rear end of the box cover is connected to the lower end of the side cover, and a zipper door is provided in the middle for human passage.

[0050] The utility model proposes a pickup truck compartment expansion device, which realizes the longitudinal expansion of the pickup truck's rear compartment space through a lifting mechanism. When the longitudinal space is fully expanded, the upper expandable bed board and the lower expandable bed board can realize the lateral space expansion. It can effectively expand the rest space and increase the overall comfort of the pickup truck. Its structure is more reasonable and stable, and it is more convenient to use.

[0051] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it.
