[0018] The beneficial effects of the patent: the central shaft rotation type vehicle door hardly increases the space occupation of the vehicle during the opening and closing process, and is safer. The pivot in the patent is located at the middle or near the middle of the height of the vehicle side, and there is a relatively long combined edge between the lower edge of the door and the vehicle floor, which can provide a spacious space for getting on and off the vehicle after the door is opened.

[0019] The vehicle door can be a whole, or a bottom door and an upper door, or a bottom door, an upper door, and a sash, and the like, which are combined structures of multiple door panels, and is a whole structure, and the vehicle door forms a space close to a semicircle after being opened, and the multiple combined structures, and the door panels can be overlapped on the pivot axis after the vehicle door is opened, to form a larger open space. As shown in Figure 5 , the bottom door 1, the upper door 2, the sash 3, and the fixed plate 4 are overlapped on the pivot axis, to form a large opening 110 on the side of the vehicle body. As shown in Figure 6 , the upper door 2, the sash 3, and the fixed plate 4 are overlapped, to form a large window 105 (relative to the combination of the first window and the second window 107) larger than the first window and the second window 107 on the side of the vehicle body. As shown in Figure 7 , the sash 3 and the fixed plate 4 are overlapped, to form the second window 107 on the side of the vehicle body. As shown in Figure 8 , the bottom door 1 and the upper door 2 are connected as a whole (which can be regarded as a whole vehicle door) and are synchronously rotated to the position where the upper door 2 is overlapped with the fixed plate 4 (at the same time, the sash 3 is also rotated to be overlapped with the fixed plate 4), to form a middle opening 109 on the side of the vehicle body. As shown in Figure 3As shown, the bottom door 1 is overlapped with the fixed plate 4 (at the same time, the sash 3 is also rotated to be overlapped with the fixed plate 4), forming a small opening 108 on the side of the vehicle body.

[0020] The sash can be opened or closed independently, and when the sash is opened independently, a window 107 is formed on the side of the vehicle body, which can realize ventilation of the vehicle, especially during driving, without affecting safety. Through the stop pin, stop hole, etc., the opening or closing of the sash 3 can be independently operated, which is convenient to use.

[0021] The clutch transmission mechanism is arranged between the bottom door and the upper door, so that the bottom door and the upper door can be rotated synchronously as a whole or individually, increasing the convenience of operation. When the clutch transmission mechanism is in the combined state, the bottom door 1 and the upper door 2 can be driven synchronously as a whole by operating the outer handle 9 outside the vehicle body, or the bottom door and the upper door can be driven synchronously as a whole by operating the inner handle 6 or the upper door handle 7 inside the vehicle, which is convenient and practical.

[0022] The clutch transmission mechanism with a clutch lever 81 and a sliding rod 82 is adopted, and the upper door handle 7 is swing-connected with the clutch lever 81. One end of the clutch lever 81 can be manually pressed down to make the sliding rod 82 disengage from the clamping groove 67 on the outer periphery of the inner disc 65 and the outer disc 66. At this time, the upper door handle 7 can achieve the upper door 2 to rotate individually. At the same time, the upper door handle 7 and the clutch lever 81 are between the inner sheet 61, the inner disc 65 and the outer sheet 62, the outer disc 66. When the upper door handle 7 and the clutch lever 81 rotate, they will pass through the inner sheet 61, the inner disc 65 and the outer sheet 62, the outer disc 66, which will not hinder the rotation of the upper door handle 7 and the clutch lever 81 around the pivot axis. The sliding rod 82 is kept in the clamping groove 67 on the outer periphery of the inner disc 65 and the outer disc 66 under the action of the elastic element 83, and the bottom door 1 and the upper door 2 will rotate synchronously as a whole. This structure is simple and ingenious, but the operation is extremely simple.

[0023] The door lock 90 is arranged to have a clever structure of clamping beads in the sliding groove on the handle shaft, the upper door sleeve and the bottom door sleeve. Through the rotation of the eccentric shaft, the position of the clamping bead in the radial direction of the pivot is changed to realize the opening and closing of the door lock. The three clamping beads are respectively located in the sliding groove on the handle shaft, the upper door sleeve and the bottom door sleeve in the radial direction. The upper door sleeve can rotate relative to the handle shaft and the bottom door sleeve, and the door lock is opened. One clamping bead is located in the sliding groove on the handle shaft and the upper door sleeve at the same time, or one clamping bead is located in the sliding groove on the upper door sleeve and the bottom door sleeve at the same time. The upper door sleeve cannot rotate relative to the handle shaft and the bottom door sleeve, and the door lock is closed. In this way, the anti-theft performance of the vehicle is improved.

[0080] For the convenience of description, the longitudinal axis direction of the electric vehicle is generally taken as the front-rear direction, and the end with two wheels (i.e., front wheels) is taken as the front end, and the end with one wheel (i.e., rear wheel) is taken as the rear end. The direction extending horizontally perpendicular to the longitudinal axis is taken as the lateral direction (width direction), wherein the direction close to the center of the electric vehicle is taken as the inner side, and the direction far away from the center of the electric vehicle is taken as the outer side.

[0081] Referring to the electric vehicle 100 shown in the drawings, there are symmetrical central axis rotation receiving type door structures 200 on the left and right sides. In the following, we will only take the central axis rotation receiving type door structure 200 on the left side as an example for description.

[0082] Example 1: Central axis rotation receiving type door structure composed of bottom door 1, upper door 2, sash 3, fixed plate 4, etc.

[0083] Referring to Figure 2 As shown, the fixed plate 4 is basically a sector with a central angle of 90°, and is fixed at the right lower corner of the left side of the vehicle body 300. The handle shaft 5 is pivoted at the left upper part of the fixed plate 4 as a pivot, and the handle shaft 5 is at the middle or near the middle of the height of the left side of the vehicle body and is perpendicular to the left side of the vehicle.

[0084] The door 400 which is basically semicircular in the circumferential direction of the pivot includes two parts, one part is the bottom door 1 which is in contact with the bottom of the vehicle body, and the other part is the upper door 2. The bottom door and the upper door are staggered in the direction of the pivot axis, and the bottom door 1 and the upper door 2 are spliced to form the door 400 in the circumferential direction of the pivot.

[0085] The bottom edge of the bottom door 1 is a horizontally extended joint edge 15 which is in contact with the bottom of the vehicle body. When the joint edge 15 of the bottom of the bottom door is in contact with the bottom of the vehicle body, the bottom door is in the closed state. When the bottom door 1 rotates along the bottom door track 101 about the pivot axis and the joint edge 15 is located on the upper part of the side of the vehicle body, a small opening 108 is formed on the side of the vehicle body, and the bottom door 1 is in the open state in which people can get on and off the vehicle. When the upper door 2 rotates about the pivot axis along the upper door track 102 relative to the bottom door 1 in the closed state, a window is formed on the door when the upper door 2 is opened.

[0086] The substantially sector-shaped bottom door 1 is fixed to the bottom door sleeve 11 which is sleeved on the upper door sleeve 21 which is rotatable relative to the handle shaft 5. The substantially sector-shaped bottom door 1 is located inside the upper door 2. The inner end of the handle shaft 5 is connected to one end of the inner sheet 61 through the inner disc 65 fixed to the inner end of the handle shaft 5, and the inner end of the bottom door sleeve 11 is connected to one end of the outer sheet 62 through the outer disc 66 fixed to the inner end of the bottom door sleeve 11. The other ends of the inner sheet 61 and the outer sheet 62 away from the pivot are connected through the grip rod 63. The inner sheet 61, the outer sheet 62, the grip rod 63, the inner disc 65 and the outer disc 66 form an inner handle 6 which drives the bottom door 1, the handle shaft 5 and the bottom door sleeve 11 to rotate about the pivot axis. The inner end of the upper door sleeve 21 is connected to an upper door handle 7 which drives the upper door 2 and the upper door sleeve 21 to rotate about the pivot axis. On the pivot axis, the inner disc 65 is opposite to the outer disc 66. The inner end of the upper door sleeve 21 and the upper door handle 7 are both between the inner disc 65 and the outer disc 66. The inner disc 65 and the outer disc 66 have clamping grooves 67 on the outer periphery.

[0087] The upper door 2 can be directly fixed to the upper door sleeve 21, and the bottom door 1 can be directly fixed to the bottom door sleeve 11. Of course, the indirect fixing method of the present embodiment can also be used. For example, the inner clamping disc one 16 and the outer clamping disc one 17 are fixed on the bottom door sleeve 11, and the bottom door 1 is riveted between the inner clamping disc one 16 and the outer clamping disc one 17. The inner clamping disc two 26 and the outer clamping disc two 27 are fixed on the upper door sleeve 21, and the upper door 2 is riveted between the inner clamping disc two 26 and the outer clamping disc two 27.

[0088] A clutch transmission mechanism 8 is arranged between the bottom door and the upper door. When the clutch transmission mechanism is in the engaged state, the bottom door and the upper door rotate synchronously. When the clutch transmission mechanism is in the disengaged state, the bottom door and the upper door can rotate about the pivot axis respectively. The clutch transmission mechanism 8 includes a clutch rod 81, a sliding rod 82 and an elastic element 83.

[0089] A clutch lever 81 is swingably connected to the upper door handle 7, and a sliding rod 82 is fixed to one end of the clutch lever 81. An elastic element 83 is arranged between the upper door handle 7 and the clutch lever 81, and the elastic element 83 contacts the outer periphery of the inner disc 65 and the outer disc 66 in a normal state. When the upper door handle 7, the upper door, and the upper door cover 21 rotate relative to the bottom door, the handle shaft 5, the bottom door cover 11, and the inner handle 6 about the pivot axis, the sliding rod 82 slides on the outer periphery of the inner disc 65 and the outer disc 66. When the sliding rod 82 is embedded in the clamping groove 67 on the outer periphery of the inner disc 65 and the outer disc 66, the upper door handle 7, the upper door, and the upper door cover 21 cannot rotate relative to the bottom door, the handle shaft 5, the bottom door cover 11, and the inner handle 6, and the upper door handle 7, the upper door, and the upper door cover 21 and the bottom door, the handle shaft 5, the bottom door cover 11, and the inner handle 6 can rotate together about the pivot axis. The clutch lever 81 can be operated to overcome the elastic force of the elastic element 83 to swing, so that the sliding rod 82 is disengaged from the clamping groove 67.

[0090] The outer handle 9 is fixed to the outer side end of the handle shaft 5, and the outer handle 9 is located on the outer side of the fixed plate 4.

[0091] The substantially sector-shaped window sash 3 with a central angle of 90° is rotatably arranged on the handle shaft, and the outer edge (rear edge) of the window sash 3 away from the pivot is slidably connected with the circular-arc-shaped window sash track 103 on the vehicle body.

[0092] The outer periphery of the bottom door front edge 12 is slidably connected with the inner periphery of the upper door front edge 22, and the outer periphery of the upper door front edge 22 is slidably connected with the inner periphery of the window sash outer edge 32. At this time, the upper door front edge 22 is the bottom door track 101, and the window sash outer edge 32 is the upper door track 102. This structure simplifies the door track structure on the vehicle body for the sliding of the bottom door, the upper door, and the window sash relative to the vehicle body. At the same time, the sealing between the three door panels, i.e., the bottom door 1, the upper door 2, and the window sash 3, is good, and the gap is smaller. Obviously, the upper door front edge 22 can not be used as the bottom door track 101, and the window sash outer edge 32 can not be used as the upper door track 102, and the bottom door track 101 and the upper door track 102 can be separately arranged on the vehicle body. The window sash track 103, the window sash outer edge 32 (or the upper door track 102), the upper door front edge 22 (or the bottom door track 101), and the bottom door front edge 12 are all circular arcs with the pivot axis as the center. The window sash, the bottom door, and the upper door can all rotate about the pivot axis.

[0093] In the direction of the pivot axis, the window sash 3 is located on the outer side of the upper door, the fixed plate 4 is located on the outer side of the window sash 3, and the window sash 3 is separated from the fixed plate 4 by the partition plate 28. In the circumferential direction of the pivot, the window sash 3, the fixed plate 4, and the closed vehicle door together form a vehicle side panel that encloses the side of the vehicle body. When the window sash 3 rotates about the pivot axis along the window sash track 103 relative to the vehicle body and the closed vehicle door, a window opening two 107 is formed on the vehicle side panel when the window sash 3 is opened.

[0094] A stop hole 35 is provided on the outer edge of the sash 3, and a stop pin 104 corresponding to the stop hole 35 is provided on the sash rail 103 so as to be slidable in the radial direction of the pivot. When the stop pin 104 is inserted into the stop hole 35, the sash 3 cannot rotate about the pivot, and at this time the sash 3, the fixed plate 4, and the door in the closed state together form a door side panel that encloses the side of the vehicle body. When the stop pin 104 is disengaged from the stop hole 35, the sash 3 can rotate about the pivot. Specifically, a stop pin hole 1041 and a push rod hole 1061 are provided on the sash rail 103 so as to extend in the radial direction of the pivot, and a stop pin 104 corresponding to the stop pin hole 1041 is slidably provided in the stop pin hole in the radial direction of the pivot, and a push rod 106 corresponding to the push rod hole 1061 is slidably provided in the push rod hole in the radial direction of the pivot. The stop pin 104 and the push rod 106 are fixedly connected. The end of the push rod 106 near the pivot extends out of the sash rail 103, so as to facilitate movement of the stop pin 104 and the push rod 106 in the radial direction of the pivot inside the vehicle body. The position of the push rod 106 in the direction of the pivot axis with respect to the sash rail 103 does not interfere with rotation of the sash 3, the bottom door 1, and the upper door 2 about the pivot. Moving the push rod and the stop pin in the direction of the pivot, the stop pin 104 or a portion of the stop pin 104 can extend into the stop hole 35 on the outer edge 32 of the sash 3, and at this time the sash 3 cannot rotate about the pivot. When the push rod and the stop pin are moved in the direction away from the pivot, the stop pin 104 is disengaged from the stop hole 35, and at this time the sash 3 can rotate about the pivot.
