The part near the roof of the fixed supporting round rod is reinforced to share the bearing pressure, so that the roof is prevented from being punctured, and the part near the floor of the fixed lifting plunger pump is also reinforced.
And secondly, translating the vehicle body. The left side body and the right side body are cut from the chassis, the rear side body and the front wall plate, the strength of the cut is lower than that of the original cut, proper reinforcement is required, for example, the cut is coated with a metal plate, because the left side car body and the right side car body are always translated in the left-right direction, for the sake of firmness, the left side car body and the right side car body bottom materials are replaced by square tube materials, the length of the square tube materials is equal to that of the left side car body or the right side car body bottom, the square tube materials are fixed with the rest original car body parts of the left side car body or the right side car body into a whole, 2-4 left side longitudinal square tubes with the length of 1-2 meters are welded on the square tube vertical to the left side car body bottom, 2-4 large square pipes are fixed on the floor of the passenger car, the number, the positions and the sizes of the large square pipes are suitable for the left longitudinal square pipe to be inserted into the square hole, a rolling bearing is arranged between the bottom surfaces of the large square pipe and the left longitudinal square pipe in contact; the other end of the large square tube is inserted with a right longitudinal square tube of a right car body with the same structure as the left car body, and a rolling bearing is arranged between the bottom surfaces of the large square tube and the right longitudinal square tube; a left short rod leading-out elongated slot is vertically fixed on the left side longitudinal square pipe, and a right short rod leading-out elongated slot is vertically fixed on the right side longitudinal square pipe; a horizontal pushing plunger pump is hinged between the left short rod and the right short rod, wherein one end of the horizontal pushing plunger pump is hinged with the outer edge of a piston of the horizontal pushing plunger pump, and the other end of the horizontal pushing plunger pump is hinged with the tail end of a pump body of the horizontal pushing plunger pump; the structures in the 2-4 large square pipes are the same as those described above.
Thirdly, using the curtain sheet to carry out containment after the volume is enlarged. Four rolling blind devices are arranged above the rectangular vehicle body, and a blind sheet of each rolling blind device has two edges, wherein one edge is fixed on a blind sheet reel, and the other edge is fixed on one edge of the rectangular vehicle body. The four rolling curtain devices are called a front rolling curtain device, a rear rolling curtain device, a left rolling curtain device and a right rolling curtain device, the other end of a curtain sheet of the front rolling curtain device is fixed at the front edge of a vehicle body, the other end of a curtain sheet of the rear rolling curtain device is fixed at the rear edge of the vehicle body, the other end of a curtain sheet of the left rolling curtain device is fixed at the left edge of the vehicle body, and the other end of a curtain sheet of the right rolling curtain device is fixed at the right edge of the vehicle body. The other end of the curtain sheet of the rear left rolling curtain device is fixed at the rear side of the left vehicle body, and the other end of the curtain sheet of the rear right rolling curtain device is fixed at the rear side of the right vehicle body. The other end of the curtain sheet of the front left rolling curtain device is fixed on the front side of the left vehicle body, and the other end of the curtain sheet of the front right rolling curtain device is fixed on the front side of the right vehicle body. When the passenger car is largest in size, two triangular blank areas are arranged at the junction of the curtain sheet of the front rolling curtain device and the curtain sheets of the left rolling curtain device and the right rolling curtain device, two triangular blank areas are arranged at the junction of the curtain sheet of the rear rolling curtain device and the curtain sheets of the left rolling curtain device and the right rolling curtain device, four triangular blank areas are designed, a plurality of small holes are formed in the edges of the curtain sheets of the triangular blank areas at equal intervals, four triangular plates with slightly larger areas than the triangular blank areas are designed, the number and the positions of the hooks correspond to the small holes in the edges of the curtain sheets of the blank areas, the hooks of the triangular plates can penetrate through the small holes from outside to inside, and the hooks are connected together by a rope or another triangular plate with holes and the rope from inside, so that the curtain sheet, the triangular plate, the car body and a new car roof outside form the closed passenger car; the triangular plates are additionally provided with folding supports, so that the two triangular plates can be used as a square table or stool when being placed on the supports. Therefore, the curtain sheet enclosure is fixed into a whole by the triangular plates with hooks at the four edges and is airtight.
And fourthly, enclosing around the floor. The left side and the right side of the floor in the passenger compartment are respectively and horizontally fixed with a rolling curtain device, the rolling curtain device is called as a left flat rolling curtain device and a right flat rolling curtain device, the other end of a curtain sheet of the left flat rolling curtain device is fixed on the lower side of a left side vehicle body, the other end of the curtain sheet of the right flat rolling curtain device is fixed on the lower side of a right side vehicle body, a flat plate is hinged on the boundary line of the left side vehicle body, the right side vehicle body and the floor, the flat plates are called as a left flat plate and a right flat plate, the length of the left flat plate and the length of the right flat plate are equal to the length of the left side vehicle body or the length of the right side vehicle body, the width of the left flat plate and the width of the right flat plate are equal to the extending length of the left flat rolling curtain device or the right flat rolling curtain device, and the strength of the left flat plate and the right plate can be overcome by a standing person. At this time, a gap is still formed between the curtain sheet of the floor and the floor, in order to seal the gap, a right-angle edge is formed at the straight edge where the left flat plate and the right flat plate are contacted with the rear vehicle body, a groove is added on the outer surfaces of the lower sides of the rear vehicle body, the left vehicle body and the right vehicle body, one straight plate is inserted into the groove of the rear vehicle body and the left vehicle body, and the other straight plate is inserted into the groove of the rear vehicle body and the right vehicle body, so that the straight plate outside the curtain sheet and the right-angle edge inside the curtain sheet squeeze the curtain sheet. In the same way, the sealing of the front wall plate and the lower side curtain sheets of the left vehicle body and the right vehicle body can be sealed.
Fifthly, the quality of the curtain sheet. The structure of the rolling curtain device is similar to that of a manual rolling door device, the rolling door device is not a curtain sheet applied in the rolling door, but the framework of the whole curtain sheet is formed by a piece of woven steel wire mesh, the outer surface of the steel wire mesh is coated with PE and PVC chemical materials with elasticity and hardness, and the inner surface of the steel wire mesh is coated with substances similar to an automobile heat insulation film. So that the curtain sheet has the following properties: one of them is thin, which facilitates to reduce the volume of the roller shutter device. For example: the diameter of the steel wire is selected to be smaller than the thickness of the iron plate of the car body. The elasticity and hardness of the coating on the outer surface of the steel wire are both the chemical material and the thickness of the substance coated on the inner surface and similar to the automobile heat insulation film, and the principle that the steel wire is just buried is taken as a rule (the thickness of an automobile body iron plate is about 1 mm, and the thickness of the heat insulation film is less than 0.1 mm). The rolling device is small and easy to hide, and the estimated diameter of the curtain sheet with the length of about 1 meter rolled up on the roller can be less than 100 mm. It is also light. The density of the rest of the wire mesh in the curtain sheet is lower than that of iron, so the weight of the curtain sheet is lower than that of an iron plate of a vehicle body. The strength of the steel wire is not lower than that of an iron plate forming the car body, the selected steel wire is not an iron wire, the strength of the steel wire is stronger than that of the iron plate of the car body, and after chemical materials are coated on the steel wire, the steel wire is cut continuously by using a common scissors and cannot be broken. And the anti-theft alarm device is added, so that the safety is realized.
Sixthly, increasing the volume index of the vehicle body. Because the common small and medium-sized passenger vehicles cannot get up in the vehicle, the raised height of the roof of the passenger vehicle is recommended to be 0.6-1 meter according to different vehicle types, and the outward translation distance of the left vehicle body or the right vehicle body is recommended to be 0.5-1 meter (the width in the vehicle is increased by 1-2 meters). The passenger car is particularly suitable for 1-2 self-driving tourists.
And seventhly, alarming and monitoring. In order to further ensure the safety, a contact or approach alarm device is arranged on the curtain sheet, so that outsiders cannot approach the passenger car. The arrangement of a panoramic monitor on the roof has the following advantages: 1. the farthest distance from the ground and the least damage possibility; 2. the system is safe and power-saving, if monitors are arranged around the passenger car, a plurality of monitors are needed to complete panoramic monitoring, the power consumption is increased, the cost is high, and the system is easy to be damaged by people; 3. on a narrow road surface, a driver cannot grasp the accurate positions of the wheels, and the monitor is equivalent to watching the road while standing on the roof and the watching positions are more accurate. The rod for mounting the panoramic camera is a straight rod, and the straight rod can be bent by 90 degrees in order to prevent the height of the straight rod from increasing to influence height-limiting passing; in order to prevent the straight rod from causing dead angles of the camera, a section of the straight rod in contact with the camera can be designed to be transparent; the camera is led to a power line and a signal line in the passenger car to select a retractable line, so that the lifting communication of the car roof is not influenced.
The roof lighting of the invention is changed, and a telescopic cable can be connected to a lifting section of the roof to restore the original circuit. The original circuit is recovered by connecting the original breaking circuit with the telescopic cable when the car door controls circuits such as lifting glass, opening and closing the door and the like. The fuel tank cover of some vehicle models can be influenced, and the fuel filling port can be changed to a rear side vehicle body. If the rear side body is originally mobile, it needs to be reinforced to be fixed to the chassis. The new roof can be a cambered surface or a streamline profile, one is small in wind resistance, and the other is attractive. If the vehicle type related to the passenger vehicle is not flat-topped, the vehicle type is transformed into the vehicle type which tends to be flat-topped after being modified as much as possible, and the space is large, so that the vehicle type is convenient to modify. The fixing modes related by the invention comprise welding, riveting, screw connection, bolt connection and bonding. The front, rear, left, right, upper, middle, lower, horizontal and vertical directions of the invention are consistent with the directions of the passenger car.
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 roof of the passenger car can be changed from low to high when the passenger car is normally opened to be 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 novel car is added with a new style, so that more choices are provided for consumers, particularly salary persons, and new vitality is brought to the market.
