A camping trolley, comprising a front trolley frame (1) and a rear trolley frame (2), wherein the front trolley frame (1) and the rear trolley frame (2) are respectively provided with a front transverse frame (3) and a rear transverse frame (4) which are opposite to each other at front and back;
- an upper folding frame (5) and a lower folding frame (6) which are opposite to each other at top and bottom are connected between two sides of each of the front trolley frame (1) and the rear trolley frame (2);
- the upper folding frame (5) comprises an upper bending frame (7) connected to the front trolley frame (1);
- the lower folding frame (6) comprises a lower bending frame (8) connected to the front trolley frame (1);
- each of the upper bending frame (7) and the lower bending frame (8) comprises a front frame section (9) and a rear frame section (10);
- the front frame section (9) is connected to the front trolley frame (1);
- a space (11) is reserved between the front frame section (9) and the rear frame section (10), and the front frame section (9) and the rear frame section (10) are rotatably connected through a bending assembly (12);
- the upper folding frame (5) is sleeved with elastic cloth (13);
- the bending assembly (12) comprises a front frame core (14) and a rear frame core (15) which are rotatably connected to each other;
- the front frame core (14) and the rear frame core (15) are slidably connected into the front frame section (9) and the rear frame section (10), respectively;
- end portions, away from each other, of the front frame core (14) and the rear frame core (15) are magnetic suction ends (16);
- magnetic suction devices (17) corresponding to the magnetic suction ends (16) are arranged in the front frame section (9) and the rear frame section (10);
- the front frame core (14) and the rear frame core (15) are internally hollowed and are provided with pressure springs (18);
- two ends of the pressure springs (18) respectively resist against the magnetic suction devices (17) and the front frame core (14) or the front frame core (14);
- a movable opening (19) is provided on the front trolley frame (1);
- a connecting seat (20) is arranged at a position, directly facing the movable opening (19), in the front trolley frame (1);
- the connecting seat (20) is connected to a pull rod assembly (21);
- the pull rod assembly (21) comprises a hinge seat (22) that is rotatably connected to the connecting seat (20);
- end holes (23) are provided at two ends of the hinge seat (22);
- limiting surfaces (24) are arranged on two sides of the hinge seat (22) facing the interior of the front trolley frame (1);
- via holes (25) located on two sides of the movable opening (19) are further provided on the front trolley frame (1);
- two pressure sensing devices (26) which are located on a rotation path of the hinge seat (22) and are in contact with the limiting surfaces (24) when the hinge seat (22) rotates relative to the connecting seat (20) are further arranged in the front trolley frame (1);
- two tension sensing devices (27) respectively located on outer sides of the two pressure sensing devices (26) are further arranged in the front trolley frame (1);
- the two tension sensing devices (27) are connected to the hinge seat (22) through tension springs (28) passing through the via holes (25) and the end holes (23) in sequence;
- and
- when both one pressure sensing device of the two pressure sensing devices (26) on one side of the two sides of the movable opening, and one tension sensing device of the two tension sensing devices (27) on an opposite side of the one side of the two sides of the movable opening, detect that acting forces are greater than respective set values, the magnetic suction device (17) on the same side as the one tension sensing device of the two tension sensing devices (27) switches from an energized state to a de-energized state, so that the front frame core (14) and the rear frame core (15) are separated from the respective magnetic suction devices (17).
