[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0023] Please see Figure 1 - Figure 7 A folding tailgate for automobiles includes an electric tailgate 1 and tailgate opening struts 2 installed at both ends of the inner side of the electric tailgate 1. A rear protective glass 3 is installed at the middle position of the side wall of the electric tailgate 1 near the tailgate opening strut 2. A foldable tail panel 4 is connected to the bottom of the electric tailgate 1 away from the tailgate opening strut 2. The foldable tail panel 4 is hinged to the side of the electric tailgate 1 near the tailgate opening strut 2 by a hinge. A folding drive mechanism is connected between the electric tailgate 1 and the foldable tail panel 4. A tailgate lock 5 is installed at the middle position of the foldable tail panel 4 away from the electric tailgate 1.

[0024] like Figure 1 - Figure 6 As shown, the folding tailgate of this utility model is similar to the existing tailgate structure. The main improvement of this utility model is that the tailgate is designed as a foldable structure, which reduces the extension length after the tailgate is opened and reduces the potential collision damage between the tailgate and the wall. Figures 1 to 6As shown in the utility model, when the folding automobile tail door is used, when the rear end of the automobile is close to the wall of the garage after the automobile reverses into the garage, the tail door lock 5 at the bottom of the foldable tail plate 4 is opened by sending an opening signal of the automobile tail door from the automobile main control, then the tail door opening support rod 2 is controlled to extend, so that the electric tail door 1 is lifted from the trunk to the outside, in the lifting process, the foldable tail plate 4 is turned inwards to the electric tail door 1 by the folding drive mechanism folding door actuator, so that the foldable tail plate 4 is folded inwards, the overall length of the automobile tail door after lifting is reduced, so that the foldable tail plate 4 is prevented from being damaged by colliding with the wall of the garage, and when there is an obstacle behind or above the automobile, the foldable tail plate 4 is folded to prevent collision with the obstacle (when the door is lifted to a distance that does not need to be folded and will not collide with the obstacle, the folding door will return to the unfolded state, leaving more headroom for the user) ; when closing the trunk, reverse operation is performed, when the electric tail door 1 is folded inwards by the tail door opening support rod 2, the foldable tail plate 4 is turned outwards by the folding drive mechanism and returns to the original position, so as to form a complete automobile tail door with the electric tail door 1, so as to close the trunk, wherein the connection structure between the tail door opening support rod 2 and the electric tail door 1 is the existing automobile tail door structure, which is installed on both sides of the trunk, which will not be described in detail, and the electric tail door 1 and the foldable tail plate 4 are both like the existing automobile tail door, and a sealing strip is installed, so as to improve the sealing effect between the electric tail door 1 and the trunk, it should be noted that the tail door lock 5, the distance sensing radar 6, the tail door opening support rod 2 and the folding drive mechanism are connected with the automobile central control system.

[0025] As Figure 1 - Figure 4 As shown in the utility model, the foldable tail plate 4 is embedded with a plurality of distance sensing radars 6. The plurality of distance sensing radars 6 are embedded and installed on the foldable tail plate 4, and the distance sensing radars 6 can be installed at the bottom end of the foldable tail plate 4 or near the connection, which can be used as the reversing radar of the automobile, and when the electric tail door 1 is lifted upwards, the distance between the foldable tail plate 4 and the obstacle behind the automobile can be detected by the distance sensing radar 6, so that the detection signal is transmitted to the automobile central control system, so as to determine whether the foldable tail plate 4 needs to be folded.

[0026] As Figure 3 - Figure 6As shown, the folding drive mechanism comprises a folding door actuator 7, and the electric tail door 1 is provided with mounting holes 101 at both ends of the side close to the foldable tail plate 4, and the two mounting holes 101 are rotatably connected with the base 8 through the rotating shaft away from the foldable tail plate 4, and the two bases 8 are fixedly connected with the bottom of the two folding door actuators 7 respectively, and the telescopic ends of the two folding door actuators 7 are connected with the turnover assembly, and the two turnover assemblies are connected with the foldable tail plate 4. When there is a nearby obstacle behind the car, in the process of opening the electric tail door 1 upward, the folding door actuator 7 is elongated, so that the foldable tail plate 4 is driven by the turnover assembly to move away from the electric tail door 1, so that it is turned inward through the hinge, and in the process of turning over, the folding door actuator 7 follows the turning of the foldable tail plate 4 in the mounting hole 101 through the base 8, and changes the angle to a certain extent. The folding door actuator 7 is preferably a combination of a motor and a gear structure or a driving push rod.

[0027] As shown in Figure 1 Figure 6 As shown, the turnover assembly comprises a U-shaped sleeve rod 9 and a fixed block 10, the U-shaped sleeve rod 9 is fixedly connected with the telescopic end of the folding door actuator 7, the inner walls of the two ends of the U-shaped sleeve rod 9 are fixedly connected with the connecting shaft 11, and the fixed block 10 is fixedly connected with the side of the foldable tail plate 4 close to the mounting hole 101. The side wall of the fixed block 10 is provided with a rotating hole 102, and the connecting shaft 11 is rotatably connected with the rotating hole 102. When the folding door actuator 7 is elongated, the fixed block 10 is pushed outward through the U-shaped sleeve rod 9 and the connecting shaft 11, and the foldable tail plate 4 is turned inward in cooperation with the hinge. In this process, when the foldable tail plate 4 is turned over, the base 8 realizes the rotation of the angle in the mounting hole 101 through the rotating shaft, and the U-shaped sleeve rod 9 rotates through the connecting shaft 11 and the rotating hole 102 of the fixed block 10, so as to complete the turnover control of the whole foldable tail plate 4.

[0028] As shown in Figure 1 Figure 6 As shown, the side of the foldable tail plate 4 close to the electric tail door 1 is provided with a U-shaped groove 401, the U-shaped groove 401 is located on the side of the foldable tail plate 4 away from the tail door opening support rod 2, the U-shaped groove 401 is fixedly connected with a U-shaped organ case 12, and the other end of the U-shaped organ case 12 is fixedly connected with the end of the electric tail door 1 close to the foldable tail plate 4. In the process of folding and turning over the foldable tail plate 4, the U-shaped organ case 12 can wrap the folding drive mechanism such as the fixed block 10 and the U-shaped sleeve rod 9 inside after folding, so as to avoid dust entering the mounting hole 101 and the connection gap between the electric tail door 1 and the foldable tail plate 4, and also can play a function of preventing clamping during the folding operation, avoiding the hands of the user being clamped between the electric tail door 1 and the foldable tail plate 4, and improving the use safety of the foldable car tail door.
