Detailed Description
Fig. 1 is a front structural view of a door of a passenger car according to an embodiment of the present invention, which is a structural view of a position of the door that is lifted to the top. Please refer to fig. 2, 3 and 4, wherein fig. 2 is a structural view of the back of the un-jacked vehicle door; FIG. 3 is a cross-sectional view of a center pillar and door structure of an un-jacked door; fig. 4 is a flow chart of a main program of the control system for completing the jacking opening and falling closing process of fig. 1, 2 and 3.
As shown in fig. 1 to 4, an embodiment of the automatic lift-up passenger car door of the present invention includes a front door 4, a rear door 4, a door center pillar 2, a stepping motor cylinder 3, a multi-stage hydraulic rod outer tube 7, a multi-stage hydraulic rod 5, and a hydraulic rod top beam 6. The front door 4, the rear door 4, and the door pillar 2 correspond to the conventional ones. The car door central column 2 is provided with a front car door U-shaped sliding groove and a rear car door U-shaped sliding groove 8 in parallel, the two sides in the front car door U-shaped sliding groove and the rear car door U-shaped sliding groove 8 are provided with U-shaped sliding groove fixing clamping plates 9, and the two sides are provided with a front car door U-shaped sliding groove between the U-shaped sliding groove fixing clamping plates 9 and a sliding rail for up-and-down sliding and lifting of the rear car door U-shaped sliding groove 8. The stepping motor hydraulic cylinder 3 is a micro stepping motor hydraulic cylinder, is in the prior art, and comprises a stepping motor, a hydraulic pump, a gear pump, a reversing valve and a hydraulic system. Two step motor pneumatic cylinders 3 are respectively recessed and embedded in the middle section position in front door U-shaped chute and back door U-shaped chute 8, and are fixed by U-shaped chute fixing clamping plates 9. One end of each of the two multi-stage hydraulic rods 5 is fixedly connected with the corresponding hydraulic cylinder 3 of the stepping motor, and the top end of the other end of each of the two multi-stage hydraulic rods is fixedly connected with the corresponding hydraulic rod top beam 6. The two multi-stage hydraulic rod outer sleeves 7 are respectively sleeved on the two multi-stage hydraulic rods 5, and the front car door 4 and the rear car door 4 are respectively connected with the corresponding multi-stage hydraulic rod outer sleeves 7 and the hydraulic rod top beams 6 into a whole. The automatic jacking type passenger car door also comprises a singlechip programmable control system, wherein the singlechip programmable control system is a singlechip 80C51 programmable control system in the prior art and is electrically connected with the stepping motor hydraulic cylinder 3. Under the state of acting of the stepping motor hydraulic cylinder 3, the multistage hydraulic rod 5 can orderly lift up and down on a slide rail in a front vehicle door U-shaped chute or a rear vehicle door U-shaped chute 8, pressure is transmitted to the multistage hydraulic rod 5 after hydraulic oil is pressurized through a gear pump, energy is transmitted to the hydraulic rod top beam 6, the multistage hydraulic rod top beam 6 drives the front vehicle door 4 or the rear vehicle door 4 to lift up, open or fall and close on a front rear column 1 of the vehicle door, and the vehicle door moves up and down to realize the whole process of opening and closing the vehicle door.
The working principle of the invention is as follows: the code structure produced by the program written by the C language is clear and meticulous in logic, and is convenient to use and maintain by adopting the singlechip 80C51 programmable control system. Therefore, the software design of the automatic lifting type passenger car door adopts C language to write programs. The control of the hardware part of the automatic control system of the software structure of the singlechip 80C51 is basically realized by the software part, and the system software is divided into three parts: the system is powered on and initialized, the control function part after the on or off switch is turned on, and the control function part after the jacking or off switch is turned off. The system is initialized once after being electrified, and each part needed to be used by the controller is initially set. After the jacking or closing switch is turned on, the jacking or closing device is automatically controlled to be in place, namely, the jacking and closing devices are both lowered to the working position, the stepping motor hydraulic cylinder 3 and the multistage hydraulic rod 5 start to operate, the inquiry of key digital input information can be realized, and when the digital input information exists, the jacking and closing devices can correspondingly operate at medium speed or high speed. After the jacking or closing switch is closed, the automatic control that the jacking or closing device is recovered to the initial position is realized, and the stepping motor hydraulic cylinder 3 and the multistage hydraulic rod 5 stop working, so that the jacking or closing can be controlled to return to the initial position.
The technical route and the principle for realizing the invention are as follows: the hydraulic oil is pumped into the hydraulic system from the oil tank through the hydraulic pump of the stepping motor hydraulic cylinder 3, and when the hydraulic oil flows through the pump body, the gear pump presses the hydraulic oil in the oil cavity to further flow to the reversing valve. When the reversing valve is arranged at the left end, hydraulic oil enters from the lower end of the hydraulic cylinder and pushes the multistage hydraulic rod 5 to move upwards to open the vehicle door. In the same way, the hydraulic oil at the upper end of the hydraulic cylinder flows back to the oil tank, when the reversing valve is arranged at the right end, the hydraulic oil enters from the upper end of the hydraulic cylinder and pushes the multistage hydraulic rod 5 to move downwards to close the vehicle door, and meanwhile, the hydraulic oil at the lower end of the hydraulic cylinder flows back to the oil tank.
The invention is obviously different from the existing similar equipment on the market, wherein: the invention is based on the traditional passenger car door, innovates the opening and closing structure of the passenger car door, uses the passenger car door and the passenger car center post as the substrate, adopts the singlechip 80C51 programmable control system, and controls the stepping motor hydraulic cylinder to push the multi-stage hydraulic rod to do work on the top beam to complete the whole process of mechanical movement of ascending and descending. The front and rear doors and the passenger car center pillar are used as carriers, the singlechip 80C51 programmable control system is adopted to control and drive the stepping motor hydraulic cylinder 3, and then the hydraulic pump acts on the multistage hydraulic rod 5, so that the whole process of controlling the passenger car door to be opened upwards and closed downwards is achieved, the multistage hydraulic rod 5 adopts a material with stronger wear resistance to effectively guarantee rigidity, the corrosion resistance of the multistage hydraulic rod 5 can be guaranteed, the hydraulic system has good self-locking performance and stability, and the safety reliability of the passenger car door can be effectively guaranteed. The problem that the door of the passenger car occupies space is solved; the manual operation process of opening and closing the door of the passenger car is solved; the embarrassment that the vehicle door can not be opened in a narrow place is solved.
The automatic jacking type passenger car door is mainly used for large, medium and small cars and the like.
The automatic jacking type passenger car door solves the problem of space saving; the safety and operation problems of drivers and passengers who open and close the door of the passenger car when the door of the passenger car runs up and down are solved, and the process of opening and closing the door in a narrow space is solved. The invention has wider applicability, higher safety and superiority of cost performance, and has market popularization prospect.
The present invention is not limited to the above-described preferred embodiments, but various modifications, equivalent substitutions, improvements and the like can be made by those skilled in the art without departing from the principle and principle of the present invention.
