[0027] As Figures 1-10 shown, the utility model provides a kind of kitchen space expansion mechanism of light motor home, it is mainly by expansion assembly 2, sunroof assembly 3 and folding support assembly 5, expansion assembly 2 is provided with stowable cabinet assembly 7, on the structure design of the two sides inner wall of vehicle body 1, a pair of installation shell 10 is symmetrically installed above, each installation shell 10 is horizontally fixed with guide rail one 11 inside;A pair of guide rail two 12 is symmetrically arranged at the corresponding position below, guide rail one 11 and guide rail two 12 are all of high-strength aluminum alloy material;

[0028] Expansion frame body 20 in expansion assembly 2 as core bearing structure, its two sides upper welding has auxiliary plate 21, auxiliary plate 21 is embedded inside installation shell 10, and inside is processed with the sliding rail one 22 matched with guide rail one 11, can realize smooth linear motion;Expansion frame body 20 two sides bottom are also provided with sliding rail two 23, cooperate with guide rail two 12, form upper and lower double-direction guiding constraint, ensure the stability when expansion frame body 20 is drawn out or retracted, expansion frame body 20 back surface installs a pair of opposite open-close door 24, uses hidden hinge connection;

[0029] A pair of parallel installation rods 30 are fixedly installed on the top of the vehicle body 1, and a sliding groove 35 is formed on the top of the installation rod 30 for accommodating the guide part of the sunroof plate 37. A pair of rotating shafts 32 are horizontally installed between the two installation rods 30 through four bearing seats 31. A chain wheel 33 is arranged at each end of the rotating shaft 32. The chain wheels 33 on the same side form a closed-loop transmission system through a transmission chain 34. A DC speed reducer motor 36 is fixedly installed on the outside of one of the installation rods 30. The output shaft of the motor 36 is rigidly connected to one end of the rotating shaft 32 through a shaft coupling, so that the transmission speed and torque can be accurately controlled.

[0030] The sunroof plate 37 is integrally formed with a sliding strip 38 at the bottom corresponding to the position of the sliding groove 35. The sliding strip 38 is embedded in the sliding groove 35 to realize horizontal sliding guidance. The sunroof plate 37 is welded with a fixing part 39 on both sides at the bottom.
