[0011] Figure 2 A schematic diagram of the traction assembly structure provided by the utility model;

[0012] Figure 3 This is a three-dimensional structural diagram of the rotary buffer structure provided by the utility model.

[0013] In the above drawings, there are a tractor head 1, a tractor trailer 2, a tractor assembly 3, a slewing buffer structure 4, a slewing disk 4-1, a first connecting part 4-2, a trailer connecting part 5, a second connecting part 4-3, a head connecting part 6, an upper disk body 4-11, a lower disk body 4-12, a torque spring 6, a mounting frame 7, a connecting frame 8, a buffer spring 9, a guide groove 10, a limit block 11, and a slide rod 12. DETAILED DESCRIPTION

[0014] The technical solutions in the embodiments of the present invention will be described clearly and completely below with reference to the accompanying drawings in the embodiments of the present invention.

[0015] like Figure 1-3 As shown, the explosion-proof battery tractor provided by the utility model includes a tractor head 1 and a tractor trailer 2, a traction assembly 3 is arranged between the tractor head 1 and the tractor trailer 2, and a slewing buffer structure 4 is arranged in the middle of the tractor assembly 3. The slewing buffer structure 4 includes a slewing disc 4-1 with upper and lower sides that can rotate with each other and elastically reset. The slewing disc 4-1 is hinged to the trailer connector 5 through a first connecting part 4-2, and the slewing disc 4-1 is hinged to the vehicle head connector 6 through a second connecting part 4-3. The first connecting part 4-2 and the second connecting part 4-3 are respectively arranged at the upper and lower parts of the slewing disc 4-1. When the distance between the tractor head 1 and the tractor trailer 2 changes, the slewing disc 4-1 plays a buffering role on the tractor trailer 2, thereby preventing the tractor trailer 2 from causing harm to the tractor trailer 2 due to the emergency deceleration of the tractor head 1 due to the emergency stop of the tractor head 1.

[0016] The rotating disk includes an upper disk body 4-11 and a lower disk body 4-12, and the upper disk body 4-11 and the lower disk body 4-12 are rotatably installed. A torque spring 6 is provided in the middle of the upper disk body 4-11 and the lower disk body 4-12, and the two ends of the torque spring 6 are respectively connected to the upper disk body 4-11 and the lower disk body 4-12. When the upper disk body 4-11 and the lower disk body 4-12 rotate, the restoring force of the torque spring 6 will slow down the rotation speed between the upper disk body 4-11 and the lower disk body 4-12, which can effectively reduce the risk of items on the tractor trailer 2 being scattered due to inertia due to emergency stop.

[0017] The trailer connector 5 includes a mounting frame 7 and a connecting frame 8, a buffer spring 9 is provided between the mounting frame 7 and the connecting frame 8, the mounting frame 7 is fixedly mounted on the tractor trailer 2, a buffer spring 9 connected to the connecting frame 8 is provided on the mounting frame 7, the connecting frame 8 is hinged to the first connecting part 4-2, and the speed change of the tractor trailer 2 is further buffered by the buffer spring 9.

[0018] The buffer spring 9 is arranged in the guide groove 10, and the guide groove 10 is used to install the buffer spring 9.

[0019] The guide groove 10 is set on the mounting frame 7, and a limit block 11 is set in the guide groove 10. The limit block 11 is fixedly connected to the slide bar 12 on the connecting frame 8, and the slide bar 12 slides with the end of the guide groove 10. The buffer spring 9 limit block 11 is connected to the inner wall of the guide groove 10. When the tractor trailer 2 is towed by the tractor head 1, the buffer spring 9 is in a compressed state. When the tractor head 1 stops suddenly, the buffer spring 9 pushes the tractor trailer 2 toward the tractor trailer 2 through the restoring force, slowing down the moving speed of the tractor trailer 2. Together with the rotary spring, the tractor trailer 2 stops slowly, reducing the risk of items on the tractor trailer 2 being scattered due to inertia.
