The principle of the invention is that the roof is removed, the periphery of the roof is framed, the frame is rectangular, four sides of the frame are provided with four rotating shafts in four directions, each rotating shaft is provided with a top plate, the added top plates are called as a front top plate, a rear top plate, a left top plate and a right top plate according to different directions, a sealed roof is formed when the four top plates rotate to cover the horizontal direction of the roof, the upward top surfaces formed by the four top plates of the front top plate, the rear top plate, the left top plate and the right top plate can be flat metal plates, and the downward top surfaces formed by the four top plates are provided with heat insulation layers. The upward top surface formed by the front top plate, the rear top plate, the left top plate and the right top plate can also be a metal surface with an arc surface or a streamline profile instead of a plane. The top surfaces of the four top plates facing downwards are provided with heat insulation layers for heat insulation in the vehicle, and the top surfaces of the four top plates facing upwards are cambered surfaces or streamline profiles. The four top plates of the front top plate, the rear top plate, the left top plate and the right top plate are rotated to the vertical direction, namely, the four vertical surfaces of the automobile body are increased, and rubber pads are added around the four vertical surfaces to enable the four vertical surfaces to be sealed, insulated and waterproof. The inner sides of the left top plate and the right top plate are respectively provided with a curtain sheet contraction device, the two curtain sheet contraction devices are provided with two reels, and one curtain sheet is bridged on the respective reels of the two curtain sheet contraction devices; when the left top plate and the right top plate are rotated and closed to the horizontal direction, the curtain sheet is exposed to the outside of the two curtain sheet contraction devices to be the shortest; when the left top plate and the right top plate are rotated to be opened to the vertical direction, the curtain sheet is exposed to the outside of the two curtain sheet contraction devices to the longest extent. The slats constitute an elevated roof. The curtain sheet, like a steel tape, is pulled out and then subjected to the elastic force of an axial spring in the direction of the pointing shaft, so that the curtain sheet is kept tensioned all the time. When the front top plate, the rear top plate, the left top plate and the right top plate rotate to the vertical direction, gaps are formed among the curtain sheets, the front top plate and the rear top plate, grooves are designed in the front top plate and the rear top plate, a square rubber air bag is installed in each groove, the top of the square rubber air bag is in large-area close contact with the curtain dividing sheet after the square rubber air bag is inflated and expanded, and the whole roof is guaranteed to be airtight and watertight. The inner surfaces of the front top plate, the rear top plate, the left top plate and the right top plate are provided with heat-insulating layers, and heat-insulating materials are coated or additionally arranged inside the curtain sheets, so that the heat-insulating performance of the vehicle is ensured.

The driving device of the front top plate, the rear top plate, the left top plate and the right top plate can also be motors, and the power supply for the operation of the motors is a passenger car direct current power supply. The sequence of actions, by anyone, is: and when the left top plate and the right top plate are closed, the front top plate and the rear top plate are closed. The reason for this is that the curtain constitutes the roof of the vehicle and only in this opening-closing sequence can the curtain function normally. Of course, before the front top plate and the rear top plate are opened, the straight pins on the front top plate and the rear top plate need to be pulled out through the lock pins of the square metal plates (through the round rods fixed on the floor); after the front top plate and the rear top plate are closed, straight pins on the front top plate and the rear top plate need to penetrate through lock pins of square metal plates (fixed on a floor through rods) to be locked, so that the front top plate, the rear top plate, the left top plate and the right top plate, namely the square metal plates, the round rods and the passenger car floor, are fixed into a whole, and the firmness of the passenger car in the driving process is ensured. When the front top plate, the rear top plate, the left top plate and the right top plate rotate to the horizontal direction for covering the roof, the front top plate, the rear top plate, the left top plate and the right top plate form a sealed roof, and the roof is an arc surface or streamline profile, wherein one is small in wind resistance, and the other is attractive. The invention relates to a connection fixing mode which comprises welding, riveting, screw connection, bolt connection and bonding. The roof lighting of the invention is changed because the roof is sometimes high and sometimes low, and the lighting lamps can be modified to the front roof panel, the rear roof panel or the inner wall of the vehicle body. The material of the invention is light and thin, and the weight of the material is not changed greatly with the load of the original roof, so the mechanical design of the original car is not changed. The position of the air pump inflation button and the position of the roof lifting button, and the position of the motor button in the vehicle are preferably convenient to use, and are mounted near a door opening or a square metal plate, for example.

The invention has the advantages that the roof of the small and medium-sized passenger car can be changed from high to low, so that the passenger car can be changed from high to low when the passenger car is normally opened and used as a tool for riding instead of walking on duty, the roof of the passenger car can be changed from high when the passenger car is in a sleeping state during traveling, the passenger car can be moved in a standing mode in the car and can sleep, and the passenger car can be used as a dual-purpose car of a caravan and a common passenger car.

The working principle of the gear shaft driving motor is as follows: referring to the upper diagram of fig. 5, when the forward rotation button 1SB1 is pressed, the main contact is closed after the coil 1KM1 is energized, the motor M1 is supplied for forward rotation, and the motor M11 is supplied for reverse rotation; the normally open auxiliary contact of 1KM1 is closed, so that the 1KM1 coil is continuously electrified after the 1SB1 is released, and the contactor is self-locked. The 1KM1 normally closed auxiliary contact cuts off the power supply of the 1KM2 coil, so that the 1KM2 main contact cannot be closed, and the interlocking between the 1KM1 and the 1KM2 is realized. When the motor positively rotates to drive the moving part to move to the position of a travel switch 1SQ1, a normally closed contact of 1SQ1 is opened, a power-off main contact of a coil of 1KM1 is opened, a normally open auxiliary contact of 1KM1 is opened, a normally closed auxiliary contact of 1KM1 is closed, and motors M1 and M11 are powered off and stop rotating. The front top plate 8 and the rear top plate 9 are in the vertical direction. Meanwhile, when the motor rotates forward to drive the moving part to move to the position of a travel switch 1SQ1, a normally open contact of the travel switch 1SQ1 is switched on, as shown in the lower drawing of fig. 5, after a coil of 2KM1 is electrified, a main contact is closed, and the motor M2 rotates forward and the motor M22 rotates reversely; the left top plate 10 and the right top plate are controlled to rotate to the vertical direction, and the principle is the same as the upper diagram of the figure 5. When the lower-drawing reverse rotation button 2SB2 of FIG. 5 is pressed, the main contact is closed after the 2KM2 coil is electrified, and the motor M2 is supplied for reverse rotation and M22 is supplied for forward rotation; the 2KM2 normally-open auxiliary contact is closed and self-locked, the 2KM2 normally-closed auxiliary contact is disconnected to cut off the power supply of the 2KM1 coil, and the linkage between the 2KM1 and the 2KM2 is realized. When the motor rotates forwards to drive the moving part to move to a position of a travel switch 2SQ2, a 2SQ2 normally closed contact is opened, a 2KM2 coil loses power, and a 2KM2 main contact is opened to stop the motors M2 and M22. The front roof panel 8 and the rear roof panel 9 are in the horizontal direction covering the roof. Meanwhile, when the motor forward rotation drives the moving part to move to the position of a travel switch 2SQ2, a normally open contact of the travel switch 2SQ2 is connected, the main contact is closed after the coil of 1KM2 is electrified, the motor M1 rotates reversely, the motor M11 rotates forward, and then the motor M3538 is disconnected and stops rotating after reaching the position of a travel switch 1SQ2, which is shown in the upper drawing of fig. 5. 1SB3 and 2SB3 are emergency stop buttons and are not used generally.
