Common house cars on the market are A type, B type, C type and off-road house car. The tail of the carriage of the common house car has two structures, one is an open tail door, and the other is a closed structure. The tail of the carriage of the closed structure house car is generally provided with a ladder to facilitate users to get on and off. The interior of the house car needs to be provided with multiple functional areas such as bed, toilet and kitchen, so that the internal space is limited and the storage space is insufficient. Therefore, the tail of the carriage of the closed structure house car is generally provided with a structure such as a shelf to expand the storage space, and such structure is usually fixed, which is very troublesome for users to take and place high objects. At present, there are structures on the market that can realize the lifting function, which adopts a folding structure and uses a hydraulic rod to drive to achieve the lifting purpose (such as the folding structure used in the lifting platform disclosed in the patent with publication number CN217124654U). However, this structure needs to stretch out a certain length in the tail direction when unfolded, which occupies a considerable space. When the house car is parked in a small space, especially in a standard parking lot, it is very inconvenient to use the lifting function, and the limitation is large. CONTENT OF THE UTILITY MODEL

Detailed Implementation

[0023] To facilitate understanding of this utility model by those skilled in the art, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings.

[0024] Reference Figures 1 to 5 The present invention provides a motorhome carriage 1 with a rear lifting device, comprising a carriage 1 and a lifting device disposed at the rear of the carriage 1. The lifting device includes a plurality of fixing mechanisms 2 disposed at the rear of the carriage 1, a lifting frame 3 movably connected to the fixing mechanisms, a support frame 4 connected to the bottom of the lifting frame 3, a storage box 5 disposed on the support frame 4, and a driving mechanism 6 disposed at the rear of the carriage 1 for driving the lifting frame 3 to move.

[0025] The lifting frame 3 is connected to the fixing mechanism 2 via a sliding assembly 7; the driving mechanism 6 includes a driving bracket 61, a winch 62 mounted on the driving bracket 61, and a winch with a cable connected to the top of the lifting frame 3. In a specific implementation, a support guide wheel 73 is provided on the top of the carriage 1 or the fixing mechanism 2. The cable passes around the support guide wheel 73 and connects to the lifting frame 3. When the winch 62 rotates, the cable is wound up or unwound. When the cable is wound up, it can pull the lifting frame 3 upward; when the cable is unwound, the lifting frame 3 descends under the action of gravity.

[0026] The fixing mechanism 2 includes several fixed seats 21 connected to the carriage 1, and connecting rods 22 connected to the fixed seats 21. The connecting rods 22 are arranged vertically, and the lifting frame 3 is movably connected to the connecting rods 22. In this embodiment, two fixing mechanisms 2 are provided, which can effectively ensure the stability of the lifting frame 3 during movement, making its operation more stable and reliable.

[0027] The sliding assembly 7 includes a connecting seat 71 connected to the lifting frame, a sliding seat 72 connected to the connecting seat 71, and a plurality of guide wheels 73 disposed on the sliding seat 72. The number of sliding assemblies 7 must correspond at least to the number of fixed mechanisms 2, or multiple sliding assemblies 7 can correspond to one fixed mechanism 2 to ensure the stability of the lifting frame 3 when it moves. In this embodiment, two guide wheels 73 are disposed on each of the opposite sides of the sliding seat 72, that is, a total of four guide wheels 73 are disposed. Through reasonable layout and synergistic action, these four guide wheels 73 can effectively reduce the possible offset or swaying of the lifting frame 3 during movement, thereby significantly improving its operational stability and reliability, and providing a strong guarantee for the efficient operation of the entire device.

[0028] The connecting rod 22 has a hollow structure with an opening on one side, through which the sliding assembly 7 is connected to the inner wall of the connecting rod 22. Specifically, the guide wheel 73 is connected to the inner wall of the connecting rod 22, and during the movement of the lifting frame 3, the guide wheel 73 rolls along the inner wall of the connecting rod 22. This rolling method allows the lifting frame 3 to move smoothly and steadily in the vertical direction, while the rolling friction between the guide wheel 73 and the inner wall greatly reduces sliding resistance and improves the operating efficiency of the entire device. In addition, the rolling of the guide wheel 73 can effectively avoid direct hard friction between the inner wall of the connecting rod 22 and the sliding assembly 7, thereby reducing wear and extending the service life of the device.

[0029] A limiting rod 31 is provided at the bottom of the lifting frame 3. The end of the limiting rod 31 extends through the opening of the connecting rod 22 and into the interior of the connecting rod 22. The connecting rod 22 is provided with a limiting member 23 that matches the limiting rod 31. The limiting member 23 is inserted into and passes through the connecting rod 22, and the limiting member 23 and the connecting rod 22 are detachably connected. In this embodiment, two limiting members 23 are provided, one corresponding to the highest position of the lifting frame 3 and the other corresponding to the lowest position of the lifting frame 3. When it is necessary to lower the lifting frame 3, the upper limiting member 23 can be pulled out.

[0030] The storage box 5 includes a first box 51 disposed at one end of the support frame 4, a second box 52 disposed at the other end of the support frame 4, and a third box 53 disposed on the first box 51 and the second box 52. There is a gap between the first box 51 and the second box 52. The first box 51, the second box 52, the third box 53, and the support frame 4 form a storage space. The first box 51, the second box 52, and the third box 53 provide storage space for users to store items. The storage space can fulfill different functions according to the user's specific needs, such as for storing large items.

[0031] In this embodiment, a spare tire 8 is provided within the accommodating space, and the spare tire 8 is connected to the lifting frame 3. When the spare tire 8 needs to be used, the lifting frame 3 is lowered to remove the spare tire 8 from it.

[0032] An extension component 9 is provided on the side of the support frame 4 away from the lifting frame 3. The extension component 9 includes an extension frame 91 connected to the support frame 4 and an extension plate 92 connected to the extension frame 91. In this embodiment, two extension frames 91 are provided to ensure the stability of the connection of the extension plate 92. The extension plate 92 can be used as a platform for placing items or as a table when the vehicle is parked.

[0033] A chassis support 11 is provided at the bottom of the carriage 1. The chassis support 11 is provided with connecting frames 12 corresponding to the fixing mechanism 2. The connecting frames 12 are fixedly connected to the fixing mechanism 2, and the number of connecting frames 12 corresponds to the number of fixing mechanisms 2. The drive mechanism 6 is connected to the chassis support 11. Specifically, the drive bracket 61 of the drive mechanism 6 is fixed to the rear end of the chassis support 11.

[0034] The lifting frame 3 of this utility model is equipped with a storage box 5, which expands the storage space of the RV. The lifting frame 3 and the fixing mechanism 2 are movably connected. Under the pull of the winch of the drive mechanism 6, it can quickly lift and lower. The lifting process only involves vertical movement and does not occupy the rear space, so it can be adapted to different places. The cooperation between the sliding component 7 and the fixing mechanism 2 enables the lifting frame 3 to move smoothly and steadily in the vertical direction, effectively reducing the possible deviation or swaying of the lifting frame 3 during movement, thereby significantly improving its operational stability and reliability.
