DETAILED DESCRIPTION
[0025] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.
[0026] The utility model discloses a motorhome with a drawer-type expansion box, comprising a carriage 1, wherein an expansion box 2 with a drawer structure which can be extended to the rear of the carriage is provided at the rear of the carriage, wherein the expansion box has a top plate 2a, a bottom plate 2b, a side wall 2c and an outer side wall 2d, and a telescopic mechanism for driving the expansion box to be extended and retracted is provided between the expansion box and the carriage; when the expansion box is retracted into the carriage, the outer side wall is flush with the rear of the carriage.
[0027] Figure 1 The figure shows a three-dimensional view of the rear side of the expansion box after it is retracted. Figure 2 The figure shows a three-dimensional view of the rear side of the expansion box after it is opened. Figure 3 The figure shows a three-dimensional view of the expansion box with the rear side opened. As can be seen from the figure, the structure of the expansion box 2 is similar to a common drawer. There is no door at the rear of the car, and icon 11 indicates a window. When the vehicle is driving, the expansion box is retracted into the car without affecting the normal driving of the vehicle; when the camp is reached, the expansion box 2 extends outward to expand the space inside the car, which greatly facilitates people's use.
[0028] In a preferred embodiment, a functional box 3 is arranged on the bottom plate at the rear of the carriage 1, and drawers, kitchen utensils, water tanks, washing machines, storage boxes, etc. can be arranged in the functional box 3. A bed 4 is arranged horizontally above the functional box, and the bed 4 is a single bed, and its length is approximately equal to the width of the carriage; the side of the expansion box 2 that opens inward faces the bed, and when the expansion box is retracted into the interior of the carriage 1, the top plate 2a and side walls 2c of the expansion box overlap with the ceiling and side walls of the carriage respectively, and the bottom plate 2b of the expansion box is composed of two folding plates connected side by side, and the inner side of the bottom plate 2b is connected to the bed, and the outer side is connected to the outer wall 2d; when the expansion box 2 is retracted into the carriage, it is squeezed by the outer wall 2d, and the two folding plates are folded upright; when the expansion box is extended, it is pulled by the outer wall 2d, and the two folding plates are spread horizontally. Figure 4 The side cross-sectional view of the expansion box after recovery is shown. Figure 5The side cross-sectional view of the expansion box is shown. With such a configuration, the bottom plate 2b moves with the expansion box 2, and can be automatically folded and spread out. After being spread out, it is kept level with the bed 4, and the single bed is transformed into a double bed, which is extremely convenient to use. It should be pointed out that during the driving process of the vehicle, due to the consideration of the structural strength and safety of the expansion box, it is not recommended to use the expansion box to expand the bed as a double bed; the double bed can be used after the vehicle stops running.
[0029] See also Figure 4 and Figure 5 In the preferred embodiment shown, the telescopic mechanism includes a cantilever guide rail 5 and a push rod 6. The cantilever guide rail is horizontally installed between the carriage 1 and the expansion box 2. The cantilever guide rail supports the weight of the expansion box and supports the expansion box to move horizontally along the cantilever guide rail; the push rod is horizontally installed between the carriage 1 and the expansion box 2 to drive the expansion box to telescopically move. In the preferred embodiment, the cantilever guide rail mainly includes a slide rail and a slide groove. The slide rail can slide back and forth along a straight line inside the slide groove. The slide groove can be installed on the side wall of the carriage, and the slide rail can be installed on the left and right side walls 2c of the expansion box 2.
[0030] In an embodiment, there are at least two cantilever guide rails 5 , which are symmetrically installed between the left and right sides of the expansion box 2 and the side walls of the carriage 1 . Figure 4 and Figure 5 In the preferred embodiment shown, there are 4 cantilever guide rails 5, which are symmetrically installed between the left and right sides of the expansion box 2 and the side walls of the carriage 1. It should be pointed out that cantilever guide rails are very commonly used in drawers, but the guide rails used in drawers are small in size, while the guide rails used in the utility model are large in size. The structures and functions of the two are the same, which will not be repeated here.
[0031] See also Figure 5 The side cross-sectional view of the expansion box after being expanded is shown. A power compartment is provided between the bed 4 and the top cover of the function box 3. The push rod 6 is installed in the power compartment. There are at least two push rods 6, which are arranged separately on the left and right sides. The outer ends of the push rods are connected to the lower edge of the outer wall 2d of the expansion box. The push rod 6 can be an electric push rod, a hydraulic push rod or a pneumatic push rod. In a preferred embodiment, the bottom plate 2b of the expansion box is also inserted into the power compartment.
[0032] See also Figure 5 In the preferred embodiment shown, a stepped groove 1a is provided on the side wall of the rear part of the carriage 1, and when the expansion box is retracted into the carriage, the outer side wall 2d can be embedded in the groove. A sealing strip is provided on the inner side of the outer side wall 2d, and when the expansion box is retracted into the carriage, the sealing strip can play a good waterproof and sound insulation effect.
[0033] In order to prevent rainwater from entering the vehicle compartment through the gap between the top plate 2a of the expansion box and the ceiling of the vehicle compartment, in some embodiments, a waterproof device is provided between the top plate 2a of the expansion box and the ceiling of the vehicle compartment 1.
[0034] exist Figure 6 In one embodiment shown, the waterproof device includes a reel-type rain shelter, and the rain shelter includes a reel 7 and a shed cloth 8. The reel is installed on the outer edge of the ceiling, and one end of the shed cloth is installed on the upper edge of the outer side wall 2d. After the expansion box is retracted into the compartment, the shed cloth 8 is rolled into the reel 7, and after the expansion box is extended, the shed cloth 8 is opened accordingly, which has a better rainproof effect.
[0035] exist Figure 7 In one embodiment shown, the waterproof device includes an upper waterproof rubber strip 9 and a lower waterproof rubber strip 10. The upper waterproof rubber strip is installed on the inner side of the ceiling and along the outer edge of the ceiling; the lower waterproof rubber strip is installed on the outer side of the top plate 2a and along the edge of the top plate 2a. When the expansion box is extended, the upper waterproof rubber strip 9 and the lower waterproof rubber strip 10 are squeezed together, which can also play a good waterproof role.
[0036] The above embodiments are for illustration only and are not intended to be limiting. Any equivalent modifications or changes made thereto without departing from the spirit and scope of the present application shall be included in the scope of the claims of the present application.
