[0033] Reference Figure 1-5 A limit block 2 is fixed at one end of the column 12, and an alarm switch 5 is installed in the limit block 2.

[0034] In the present invention, the tailgate assembly 3 comprises a frame, a lifting arm, a cargo platform, and a power unit;

[0035] 1. The frame is welded with the lifting arm mounting plate, lifting cylinder mounting plate, tilting cylinder mounting plate and the frame square tube, which ensures the coaxiality and the consistency of the product.

[0036] 2. The lifting arm is welded with the lifting arm body and the welding ring, while ensuring high dimensional accuracy and consistency with the large plate and the frame during installation;

[0037] 3. The cargo platform is laser-cut and welded from high-strength alloy steel. Its connection to the lift arm cylinder ensures consistent coaxiality. When closed, the entire platform fits tightly against the sealing structure of the rear door frame, effectively replacing the tailgate seal.

[0038] 4. The power unit can be composed of a hydraulic cylinder, a hydraulic pump station or an electric cylinder and a motor.

[0039] The limit block 2 is made of rubber material, which can limit the tail plate after it comes into contact with it and have a certain sealing effect, making up for the shortcoming of poor sealing of the patterned plate; at the same time, it adopts a design to prevent water ingress, allowing rainwater to be discharged out of the car along the water groove in the limit block, preventing water from entering the car.

[0040] The sealing strip adopts penguin-shaped EPDM rubber sealing strip; the penguin-shaped sealing strip is a double-lip bubble structure, which is compressed on both sides of the tail plate to achieve multiple sealing.

[0041] The two columns 12, the upper crossbeam 9, the lower crossbeam 11, and the first rain canopy 8 constitute the rear door frame structure of the carriage. The columns 12 in the rear door frame structure of the carriage are equipped with sealing strips 10. The sealing strips 10 are made of rubber material. When the tailgate is flipped and closed, the sealing strips 10 are compressed to achieve sealing on both sides of the tailgate. The sealing strips 10 are connected to the rear door frame columns by a snap-fit ​​strip. The snap-fit ​​strip is an Ω-shaped thin steel plate that snaps into the front end surface of the column 12.

[0042] A first rain canopy 8 is designed on the upper portion of the upper crossbeam 9 in the rear door frame structure of the carriage to prevent rainwater from dripping into the inner side of the rear door frame.

[0043] The upper small door 4 is composed of a door frame 16, a door core 17, an upper sealing strip 15, and a second rain canopy 14. The upper PVC sealing strip is a clip-on structure that is clipped to the edge of the door frame. The lower EPDM sealing strip is an adhesive structure that is bonded to the front of the second rain canopy 14. The left and right EPDM sealing strips are adhesive structures that are bonded to both sides of the door panel.

[0044] 1. The door frame 16 is a rectangular tube structure, the door core is a flat plate, and the rain eaves are bent parts;

[0045] 2. The upper small door 4 is sealed with the rear door frame through the left and right and upper sealing strip lips, and is compressed and sealed with the tail panel through the lower sealing strip;

[0046] 3. A second rain canopy 14 is designed above the lower sealing strip to enhance the rainproof performance between the upper small door 4 and the tail plate.

[0047] The position sensor 20 is arranged on the frame hanging plate 21. When the tail lift platform 23 is raised to the height of the car platform, the lifting arm 22 triggers the position sensor 20. When triggered, on the one hand, it plays a limiting role to ensure that the lifting height of the lifting arm 22 is flush with the car floor. On the other hand, it is used to count the number of cycles of tail lift loading and unloading, and to remind the maintenance of the tail lift. In actual production use, 1800 cycles will remind maintenance.

[0048] The voltage tilt sensor 7 is arranged at the lower right corner of the back of the tailgate platform 23. The voltage tilt sensor 7 is a dual-axis tilt sensor that can simultaneously monitor the tilt angles of the tailgate platform 23 in the front, back, and left and right directions. When the tilt angle of any side is ≥2°, the alarm switch 5 is triggered to alert the user, thereby improving safety.

[0049] The front and rear tilt reminder is used to prevent overloading of cargo, and the left and right tilt reminder is used to prevent the loading position of cargo from being too offset and away from the loading center.

[0050] The alarm switch 5 consists of an alarm trigger button and a yellow warning light 1. When the trigger button is touched, the yellow warning light 1 flashes to alert the user and a buzzer sounds. The trigger button is arranged on the limit block 2 of the rear door frame of the vehicle, and the yellow warning light 1 is arranged in the middle position of the upper crossbeam 9 of the rear door frame. The alarm switch 5 is mainly used to remind the user that the tailgate is not closed and to remind the user of misoperation to prevent pinching. In addition, it is combined with the voltage tilt sensor 7 to warn of overload and offset. The alarm switch 5 triggers the alarm when the following situations occur:

[0051] 1. When the vehicle is traveling at a speed greater than 0 and the tailgate does not touch the alarm switch 5 on the rear door frame, the alarm switch 55 will be triggered.

[0052] 2. When the vehicle is stopped, the tailgate upturn button is activated. If the alarm switch 5 is not pressed for more than 15 seconds, the alarm mechanism of the alarm switch 5 is triggered;

[0053] 3. When loading and unloading goods, when the voltage tilt sensor 7 tilts in any of the two directions of front and back and left and right by 2 degrees, the alarm switch 5 alarm mechanism is triggered.

[0054] At the same time, a PLC circuit board needs to be set up during actual production and preparation. The PLC circuit board is used to connect various sensors and alarm switches 5, receive their signals, complete signal conversion and complete instruction output, and set a display to display the statistics of the number of lifts, maintenance reminders, and the normal and abnormal functions of the tailgate. The display is arranged in the cab.

[0055] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
