[0029] like Figure 1-7As shown, a mobile house base comprises: a base 1, a wheel assembly 2 is arranged below the base 1, the wheel assembly 2 comprises a support seat 201, a limiting plate 202 is fixedly connected to the right side of the support seat 201, a rotating shaft 203 is passed through and rotatably connected to the front and back sides of the support seat 201, a roller seat 204 is fixedly connected to the front and rear ends of the rotating shaft 203, and a roller 205 is arranged on the roller seat 204. The number of wheel assemblies 2 is two groups, which are symmetrically arranged below the base 1, and the number of support seats 201 and limiting plates 202 in each group of wheel assemblies 2 is two. A driving assembly 3 is arranged between the two groups of wheel assemblies 2, and the driving assembly 3 comprises a slide rail 301, a rack 302 is slidably connected to the bottom of the slide rail 301, the cross-sectional shape of the slide rail 301 is trapezoidal, and a dovetail groove matched with the slide rail 301 is arranged on the rack 302. A driving device 303 is arranged on the front side of the rack 302, and the driving device 303 specifically comprises a hydraulic push rod, the left The right two ends are fixedly connected with connecting blocks, wherein the connecting block on the left is connected to the base 1, and the connecting block on the right is connected to the rack 302. The rack 302 is driven to slide on the slide rail 301 by the driving device 303, thereby driving the retraction and extension of the wheel assembly 2. A left first gear 304 and a right gear 305 are meshed below the rack 302. The right gear 305 is fixedly connected to the outer surface of the rotating shaft 203 on the right side. The front and rear ends of the left first gear 304 are rotatably connected with support plates 306. The support plate 306 is fixedly connected to the bottom of the base 1. The rack 302 passes between the two support plates 306. A left second gear 307 is meshed on the left side of the left first gear 304. The left first gear 304 is higher than the left second gear 307. The rack 302 will not mesh with the left second gear 307. The left second gear 307 is fixedly connected to the outer surface of the rotating shaft 203 on the left side. A support assembly 4 is arranged below the base 1.

[0030] like Figure 1-7 As shown, specifically, the base 1 is moved by the roller 205. When the roller 205 needs to be folded up, the driving device 303 is first used to drive the rack 302 to slide to the right on the slide rail 301, and the rack 302 will drive the right gear 305 to make the rotating shaft 203 on the right side rotate clockwise. At the same time, the rack 302 will drive the first gear 304 on the left side to rotate clockwise, and the first gear 304 on the left side will drive the second gear 307 on the left side to rotate counterclockwise, so that the rotating shaft 203 on the right side rotates counterclockwise. The roller seat 204 is flipped by the rotation of the two rotating shafts 203 to fold the roller 205 and fold it under the base 1, so as to achieve the purpose of folding the roller 205.

[0031] like Figure 1-7As shown, the support assembly 4 includes a rotating seat 401, which is rotatably connected to the bottom of the base 1, a support leg 402 is fixedly connected to the bottom of the rotating seat 401, and an annular tooth 403 is fixedly connected to the outer surface of the rotating seat 401. The number of support assemblies 4 is four groups, which are symmetrically arranged at the four corners below the base 1 front and back, left and right, respectively. A gear assembly 5 is arranged between each group of support assemblies 4 and the wheel assembly 2. The gear assembly 5 includes a bevel gear 501, which is fixedly connected to the outer surface of the rotating shaft 203, and a crown gear 50 is meshed above the bevel gear 501. 2. A rotating column 503 passes through and is fixedly connected to the middle of the crown gear 502. The rotating column 503 is rotatably connected to the bottom of the base 1.

A second connecting gear 505 is meshed with the right side of the first connecting gear 504. The second connecting gear 505 is rotatably connected to the bottom of the base 1. The second connecting gear 505 is meshed with the annular tooth 403. There are four groups of gear assemblies 5, which are symmetrically arranged at the four corners below the base 1 in front, back, left and right directions.

[0032] like Figure 6 As shown, specifically, when the rack 302 drives the rotating shaft 203 to rotate, it will also drive the gear assembly 5 and further drive the support assembly 4. Taking the group of gear assembly 5 and support assembly 4 located at the right rear as an example, the clockwise rotation of the rotating shaft 203 located on the right side will drive the bevel gear 501 to rotate clockwise, and the rotation of the bevel gear 501 will drive the crown gear 502 to rotate clockwise, and the first connecting gear 504 connected to the crown gear 502 through the rotating column 503 will also rotate clockwise, the first connecting gear 504 will drive the second connecting gear 505 to rotate counterclockwise, and the second connecting gear 505 will drive the annular gear 403 to rotate the rotating seat 401 clockwise. When the wheel assembly 2 is folded, the rotating seat 401 will rotate the support leg 402 out from under the base 1, so that the support assembly 4 is opened to play a supporting role.
