DETAILED DESCRIPTION
[0021] The present invention will be further described below in conjunction with the accompanying drawings, but the protection scope of the present invention is not limited to the following description.
[0022] like Figures 1 to 5As shown, a hidden tailgate of an automobile is shown, which includes a plurality of interconnected tailgates 1, which are rotatably connected to each other and can be folded up. A connecting seat is fixedly connected to one side of a tailgate 1 at the end, which is connected to an external driving structure through the connecting seat. The driving structure is installed at the bottom of the automobile. The tailgate 1 can be retracted under the vehicle body 1 through the driving structure and the foldable tailgate 1, thereby hiding the tailgate 1 at the bottom of the automobile. The structure for driving the tailgate 1 belongs to the existing mature technology. One side of the plate 1 is provided with an inclined surface, and the bottom side of the tail plate 1 is fixedly connected to two guide plates 2, which are symmetrically distributed on one side of the tail plate 1. A guide slot 3 is provided on one side of the two guide plates 2. The bottom side of the tail plate 1 is fixedly connected to two mounting blocks 4, which are symmetrically distributed on the bottom side of the tail plate 1. One side of the two mounting blocks 4 is rotatably connected to a bidirectional screw rod 5 through a bearing. The stability of the bidirectional screw rod 5 during rotation can be ensured by the mounting block 4. One end of the bidirectional screw rod 5 is fixedly connected to a crank 6, which facilitates the bidirectional screw rod 5 to rotate. Rotation, the outer surface of the bidirectional screw rod 5 is threadedly connected to two moving plates 7, the two screw rods of the bidirectional screw rod 5 have the same pitch, and the two screw rods of the bidirectional screw rod 5 rotate in opposite directions, so that the two moving plates 7 can make relative motion at the same time and move the same distance, and both ends of the two moving plates 7 are fixedly connected with a moving seat 8, the width of the moving seat 8 is greater than the width of the guide slide 7, the moving seat 8 fits with the guide plate 2, and the moving seat 8 is slidably connected to the guide plate 2, so that the moving seat 8 can move smoothly, and the four moving seats 8 are fixedly connected with a guide on the side away from the moving plate 7 Slide block 9, wherein one end of the two guide slide blocks 9 is fixedly connected with an extension pad 10. When the hidden car tailgate is used, if the volume of the object to be transported is large, the bidirectional screw rod 5 is rotated by the crank 6. At this time, the two movable plates 7 simultaneously drive the movable seat 8 and the guide slide block 9 to move at the same time. As the guide slide block 9 moves, the extension pad 10 moves away from the tailgate 1. The extension pad 10 is adjusted to a suitable position according to the actual situation of the object. At this time, the tailgate 1 and the extension pad 10 are used together to support and transport the object.
[0023] As an optional technical solution of the present invention, a receiving groove 11 is provided on one side of the guide slider 9, and the inner wall of the receiving groove 11 is rotatably connected to a supporting rotating rod 12, and one end of the supporting rotating rod 12 is threadedly connected to a screw pad 13, and a fixing socket 14 is provided on the end of the supporting rotating rod 12 away from the screw pad 13. One side of the extension pad 10 is fixedly connected to two support blocks 15, and one side of the two support blocks 15 is threadedly connected to a fixing bolt 16. If the distance between the extension pad 10 and the tail plate 1 is large, the guide plate 2 is not Then block the supporting rotating rod 12, and move the supporting rotating rod 12 out from the inside of the storage groove 11, so that the supporting rotating rod 12 is rotated to a vertical state. At this time, the fixing bolt 16 corresponds to the position of the fixing socket 14. Rotate the fixing bolt 16 to connect it with the fixing socket 14, fix the supporting rotating rod 12, and fix the supporting rotating rod 12 in a vertical state. Then the screw pad 13 can be rotated and contacted with the ground. At this time, the guide slider 9 is supported by the screw pad 13 and the supporting rotating rod 12.
[0024] As an optional technical solution of the present invention, the guide slider 9 and the guide groove 3 are both T-shaped, and the guide slider 9 is adapted to the size of the guide groove 3. The guide slider 9 and the guide groove 3 guide the movable seat 8 and the movable plate 7, so that the movable plate 7 and the movable seat 8 can only move linearly along the direction of the guide groove 3, and can ensure that the guide slider 9 will not separate from the guide plate 2 during the smooth movement.
[0025] As an optional technical solution of the present invention, the length of the extended pad 10 is the same as the width of the tail board 1, and the upper surface of the extended pad 10 is on the same horizontal plane as the upper surface of the tail board 1, so as to better support the objects located on the tail board 1.
[0026] As an optional technical solution of the present invention, the sum of the length of the supporting rotating rod 12 and the length of the screw pad 13 is less than the length of the storage groove 11, and the thickness of the supporting rotating rod 12 is less than the depth of the storage groove 11, so that the supporting rotating rod 12 and the screw pad 13 can be smoothly stored in the interior of the storage groove 11, avoiding the situation where the supporting rotating rod 12 and the screw pad 13 are exposed to the outside.
[0027] As an optional technical solution of the present invention, the position of the fixing bolt 16 corresponds to that of the fixing hole 14 , and the size of the fixing bolt 16 is adapted to that of the fixing hole 14 , so that the fixing bolt 16 can be smoothly connected to the fixing hole 14 .
[0028] The working principle of a hidden car tailgate for transporting large objects is as follows:
[0029] 1) Use the crank handle 6 to rotate the bidirectional screw rod 5. At this time, the two moving plates 7 simultaneously drive the moving seat 8 and the guide slider 9 to move simultaneously. As the guide slider 9 moves, the extension plate 10 moves away from the tail plate 1. Adjust the extension plate 10 to the appropriate position according to the actual situation of the object;
[0030] 2) If the support rotating rod 12 is removed from the guide slot 3 at this time, the support rotating rod 12 is rotated to a vertical state, and the position of the fixing bolt 16 corresponds to the position of the fixing hole 14;
[0031] 3) Rotate the fixing bolt 16 to connect it with the fixing socket 14, thereby fixing the support rotating rod 12 and fixing the support rotating rod 12 in a vertical state;
[0032] 4) The screw pad 13 is rotated and contacts the ground. At this time, the guide slider 9 is supported by the screw pad 13 and the supporting rotating rod 12. At this time, the tail plate 1 and the extension pad 10 can jointly support the object.
[0033] In summary, the hidden car tailboard is equipped with the tailboard 1, the guide plate 2, the guide slide 3, the mounting block 4, the two-way screw rod 5, the crank 6, the movable plate 7, the movable seat 8, the guide slider 9 and the extension pad 10. When encountering large items, the extension pad 10 can be adjusted to a suitable position. The large items are supported by the extension pad 10 and the tailboard 1, thereby expanding the support range of the hidden car tailboard, greatly avoiding the situation that large items fall, ensuring the integrity of large items, and improving the practicality of the hidden car tailboard. 13, the matching arrangement of the fixing socket 14, the support block 15 and the fixing bolt 16, when the guide slider 9 is moved out of the guide slide groove 3 for a large length, the distance between the extension pad 10 and the tail plate 1 is large. At this time, the support rotating rod 12 can be moved out from the inside of the storage groove 11, and the support rotating rod 12 is fixed in a vertical state, and the screw pad 13 is made to fit the ground, so that the extension pad 10 and the guide slider 9 can be supported when transporting large items, thereby ensuring the structural stability of the guide slider 9 of the extension pad 10, greatly avoiding the bending of the guide slider 9 and the extension pad 10, and being able to stably support the items.
