Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one such feature.

As shown in fig. 1-4, the pickup truck tail door with the hidden ramp of the utility model comprises a tail door body 1 longitudinally mounted at the tail end of a cargo box of a pickup truck, wherein the tail door body 1 is in a rectangular structure and is internally provided with a mounting chamber; in addition, the upper edge of the tail gate body 1 is a turnover cover plate 2 for rotating to open or close the installation cavity, and the outer edge of the turnover cover plate 2 is hinged to the tail gate body 1 through a return torsion spring 3, so that the turnover cover plate 2 can be tightly buckled on the tail gate body 1 under the driving of the return torsion spring.

A transmission mechanism is arranged in the installation cavity of the tail gate body 1, and the transmission direction of the transmission mechanism is consistent with the direction of the short edge of the tail gate body 1; in addition, the transmission mechanism can be arranged on the left side or the right side of the installation cavity, and certainly, a group of transmission mechanisms can be respectively arranged on the left side and the right side of the installation cavity, so long as the two groups of transmission mechanisms can work simultaneously and in the same direction. Specifically, the transmission mechanism comprises a driving motor 4, a transmission gear 5 and a transmission chain 6; wherein, driving motor 4 is fixed in on the inner wall of installation cavity, and drive gear 5 is two, sets up along the minor face direction interval of tail-gate body 1, and wherein a drive gear 5 should coaxial solid cover on driving motor 4's drive shaft, and drive chain 6 is around locating on two drive gear 5 to be connected with two drive gear 5 meshing, drive chain 6 by drive gear 5's rotation promptly and rotate.

A slope plate 7 is also arranged in the installation cavity of the tail gate body 1, and the slope plate 7 is connected with the transmission mechanism and driven by the transmission mechanism to move; driven by the transmission mechanism, the slope plate 7 has a first state of being taken into the installation cavity and a second state of being pushed out of the installation cavity from the turnover cover plate 2. Specifically, the slope plate 7 is of a rectangular structure, the long side direction of the slope plate 7 should be consistent with the long side direction of the tailgate body 1, and the short side direction of the slope plate 7 should be consistent with the length direction of the transmission chain 6 (i.e. consistent with the short side direction of the tailgate body 1); in addition, a corner of the slope plate 7, which is far away from the turnover cover plate 2, is fixedly connected to an upper layer chain belt or a lower layer chain belt of the transmission chain 6 through a connecting claw 8, so that the slope plate 7 can move along with the movement of the transmission chain 6, and the conversion of the slope plate 7 between the first state and the second state is completed. Of course, if a set of transmission mechanisms are respectively arranged on the left side and the right side of the installation cavity, the slope plate 7 should be located between the two sets of transmission mechanisms, and the left corner and the right corner of the slope plate 7 far away from the side of the flip cover plate 2 should be fixedly connected to the transmission chain 3 through a connecting claw 8 respectively.

Still be provided with a slewing mechanism in the installation cavity of tail-gate body 1, slewing mechanism is located the installation cavity that is close to upset apron 2 department, and slewing mechanism can set up in drive mechanism's homonymy, also can set up at the opposite side relative with drive mechanism, and certainly still a set of slewing mechanism can be arranged respectively in the left and right sides of installation cavity, as long as guarantee two sets of slewing mechanism and the work of syntropy simultaneously can. In addition, when the ramp 7 reaches the second state under the driving of the transmission mechanism, the rotation mechanism and the ramp 7 are connected in a butt joint manner through a pair of connection mechanisms, and certainly, if there are two sets of transmission mechanisms and two sets of rotation mechanisms, two sets of connection mechanisms need to be correspondingly arranged, so that the ramp 7 can be turned over from the second state to a third state in which the outer edge is lapped on the ground under the driving of the rotation mechanism. Specifically, the rotating mechanism is a rotating motor 9 fixed on the inner wall of the installation cavity of the tail gate body 1. The docking mechanism comprises a first docking gear 10, a rotating rod 11 and a second docking gear 12; the first butt-joint gear 10 is coaxially and fixedly sleeved on a rotating shaft of the rotating motor 9, the rotating rod 11 is vertically and fixedly connected to one corner of the slope plate 7 far away from the side of the turnover cover plate 2, and the axial direction of the rotating rod 11 is consistent with the long edge direction of the slope plate 7; the second butt-joint gear 12 is coaxially and fixedly sleeved on the rotating rod 11, and when the slope plate 7 moves to the second state, the second butt-joint gear 12 is in adaptive engagement with the first butt-joint gear 10, and then the slope plate 7 in the second state can be driven by the rotating mechanism to continue to move to the third state.

In addition, a sensor 13 is arranged in the installation cavity close to the turnover cover plate 2, the sensor 13 is positioned on the motion track of the connecting clamping jaw 8 and keeps corresponding to the position of the slope plate 7 when moving to the second state, so that the sensor 13 can be in contact with the connecting clamping jaw 8 moving to the position of the second state along with the slope plate 7, the position information of the slope plate 7 when reaching the second state is timely transmitted to the control device, the control device automatically controls the driving motor 4 to stop working, and the rotating motor 9 starts to rotate to drive the slope plate 7 to turn downwards and lap the ground.

When the trunk door is used, the trunk door body 1 is firstly turned outwards to be opened, so that the trunk door body is kept in a horizontal state (the trunk doors of the existing pickup trucks can only be opened to the horizontal position); then, the driving motor 4 is controlled to work to drive the slope plate 7 fixedly connected to the transmission chain 6 to move towards the direction of the turnover cover plate 2, so that the turnover cover plate 2 is pushed to be opened, and the slope plate 7 is pushed out of the installation cavity; when the slope plate 7 moves in place (namely, when the slope plate 7 moves to the second state), the connecting clamping jaws 8 fixedly connected to the transmission chain 6 can be attached to the sensor 13, and then the sensor 13 sends a signal that the slope plate 7 reaches the second state, so that the control device receiving the signal can timely control the driving motor 4 to stop working and the rotating motor 9 to start working to drive the slope plate 7 to turn downwards and lap the slope plate on the ground, thus a slope convenient for loading and unloading articles can be formed behind a container of the pick-up truck, large articles or articles with larger weight can be directly pushed onto the container of the pick-up truck, a proper carrying tool is not required to be additionally found, the defect that the pick-up truck is difficult to carry the articles is effectively overcome, frequent loading and unloading of operators is not required, and the labor intensity is greatly reduced.
