Description of the Invention: [Technical Field] The present invention relates to a door opening and closing device, and more particularly to a rotary door opening and closing device. [Prior Art] Since the door opening and closing structure which is currently commonly used for general vehicles includes mainly hinged, rail type, and sickle type or gull wing type doors. Please refer to Figure 1A • shown. The hinged side door 10, which is currently widely used in general vehicles, requires a large lateral space width change to fully open the door to allow passengers to enter and exit the car. There are two major drawbacks to this type of opening: (a) Due to site restrictions, in many cases, the door cannot be fully opened, making it inconvenient for passengers to get in and out of the cabin. (b) After the traditional door is fully opened, the door portion of the vehicle body is easily caused to cause a collision accident with the passing of the steam locomotive. Please refer to FIG. 1B again. Some of the large-scale SUVs use the track-type side-sliding door. The change in the lateral width of the $11 change is small, and there must be enough upper and lower body frame lengths to install the door, so it is not suitable for installation in the general double door. Small car. See also Figure 1C. In some advanced sports cars, the shovel-type front swing door 12 or the gull-wing door is still located at the passenger's entrance after being screwed out, so although the space required for the door opening can be greatly reduced, There are still some shortcomings that are inconvenient for passengers to enter and exit. SUMMARY OF THE INVENTION An object of the present invention is to provide a rotary door opening and closing device for decelerating the 201119888 motor to push (pull) a screw that connects the door, and complete the translational rotation of the door to open and close. To solve the above object, the rotary door opening and closing device of the present invention is connected to a vehicle body and a door, and the structure thereof comprises: a fixing seat disposed on the vehicle body, having a liner; and a power transmission fixed to the fixed seat or the vehicle body The device has a reciprocating linear drive rod; and a door rotation opening and closing assembly mounted between the door and the linear drive rod, having a compound stroke of translational and rotational elongation, and the door rotation opening and closing assembly includes: one wearing a nut disposed in the liner, having a plurality of internal threaded screw holes; and a translational rotating member having a screw threaded through the inner diameter of the nut, having a plurality of spirals corresponding to the internal threads of the screw hole, The screw head end is fixed to the door, and the screw tail end pivots a rotating connecting rod which can rotate coaxially with respect to the screw, and rotates the connecting rod and can linearly move the linear driving rod. The power transmission device may be fixed to the fixing base, the linear driving rod is parallel to the rotating connecting rod and connected by a connecting rod; or the power transmission device is fixed to the vehicle body, and the linear driving rod is connected with the rotation The rods are on the same axis and are connected to each other. The invention is characterized in that the door rotation opening and closing assembly of the composite stroke capable of translational and rotational expansion and contraction is applied, so that the door can be completely opened in a narrow space, and the side open door of the general market must have a large amount of lateral space to be at a large angle. Open, convenient for passengers to get on and off, and the opening fulcrum of this rotary door can be located behind the driver's seat, which can effectively overcome the problem that the lower part of the door of the guillotine-type door or the gull-wing door hinders passengers from entering and leaving the cabin. 201119888 Below the calf When the part enters and exits the vehicle inspection, it can also increase the passenger's instantaneous space for getting on and off. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The embodiments of the present invention will be described in detail below with reference to the drawings, and the simplified schematic diagrams are merely illustrative of the basic aspects of the invention. Therefore, in the scales of the towel, only the components of the section of the book are issued, and the components or steps are not shown, and the number, shape, size, etc. of the implementation are added to the actual system. The size of the component or the number of steps may be more complicated. ❿照® 2Saki (4) The rotary door opening and closing of the present invention is an exploded perspective view of the example and a perspective assembly view of the embodiment of Fig. 2 illustrated in Fig. 3. In the present invention, the rotary vehicle (10) (four) is placed in a two-way manner for connecting the vehicle body 6 and the door A. The rudder opening and closing device 20 includes: a seat 21 provided on the body sill, the fixing Seat 21 has a view: 211 (& good (4) no oil bushing). - Power transmission device: In this case, it has a linear drive rod 221 which is reciprocally movable. - The vehicle (10) turns the opening and closing assembly %, which is installed and connected to σ between the four door A and the linear driving rod 221, and has a compound stroke of translational and rotational elongation, and the rim rotation opening and closing component knows: With the nut of the tube 211, the eyepiece 31 has a screw hole 311 having a plurality of internal threads 3111; and a π 姑 十 and a ten-turn condensing member 32 having The sleeve is attached to the 201119888 nut W screw hole 311 (four) rod 321 , the ja 3r vt- ^ ^ 1 has a plurality of spirals 322 corresponding to the screw internal thread 3111, the 323 is fixed with the turn f1A (this implementation For example, in the direction indicated by the front end of 32...t on the left side of the vehicle body B, the screw tail end can be used as the rotary link of the screw 321 coaxially freely rotating as a lever 3241 and can accept the linear drive rod. The drive of 221 moves linearly. The surface of the nut 31 of the door rotation opening and closing assembly 3G is provided with a mountain axial seat 312' and the nut 31 is formed by the pin 212 肷a ' on the fixing base 21 of the fixing base 21 to the liner 2 (4) The direction of the axial relative movement is limited to: a radial positioning hole is provided in the axial slot 312 of the nut 31. The top surface of the head end of the bolt 212 is spherical and is applied to the liner 2U. Upper elastic member 314 (such as a spring, a spring, etc.) and the liner 211

In this embodiment, the device 22 can be fixed to the vehicle body, and the linear driving rod 221 is identical to the rotating connecting rod 3241. The axis is connected to each other. In the above embodiments, the present invention is characterized in that the present invention applies a door rotation opening and closing assembly that moves and rotates and retracts the composite stroke, and the door is fully opened in a narrow space when the door is fully opened. After comparing the door volume with the traditional door, there is even a chance to reduce the door opening volume by more than 6〇%. Overcoming the fact that the side open door on the market must have a lot of horizontal space to open at a large angle, which is convenient for passengers to get on and off. The opening fulcrum of the rotary door can be located behind the driver's seat, which can effectively overcome the problem of the passenger's entry and exit of the idler door or the lower part of the _-type door. It also increases the passenger's speed when getting on and off the car. 201119888 The space of the warehouse, and only need to be opened by remote control, the simple door surface can make the original vehicle door design more diversifiedIn the above, it is merely described that the present invention is an embodiment or an embodiment of the technical means for solving the problem, and is not intended to limit the scope of the practice of the present invention.
