[0002] Many sports enthusiasts like to move their sports equipment outdoors, but since most sports equipment is large and inconvenient to pack into a backpack, many sports enthusiasts turn to using sports equipment moving carts to move it.

[0003] Existing sports equipment transport vehicles have the following disadvantages: 1. Many existing sports equipment transport vehicles do not have top guardrails, which makes it easy for sports equipment to slip off the vehicle during transport.

[0004] 2. The existing sports equipment transport carts cannot be folded, which makes them take up a lot of space when not in use.

[0005] Therefore, we have made improvements and proposed a convenient sports equipment transport vehicle. Summary of the Invention

[0037] In one specific embodiment of the present invention, the swing device 210 includes a second stepper motor 2101, which is located inside the cavity of the vehicle body 1001. The fixed end of the second stepper motor 2101 is fixedly connected to the cavity of the vehicle body 1001. The cavity of the vehicle body 1001 is rotatably provided with a second bidirectional lead screw 2109 and a first lead screw 2105.

[0038] During operation, a second bidirectional lead screw 2109 and a first lead screw 2105 are rotatably mounted within the inner cavity of the vehicle body 1001, allowing them to rotate within the cavity. A third bevel gear 2102 is driven by the output shaft of a second stepper motor 2101, enabling the second stepper motor 2101 to rotate.

The end of the fourth connecting rod 2107 away from the second lead nut 2106 is hinged to the inner wall of the fourth groove 2108.

[0040] During operation, a third nut 2110 is threadedly connected to both sides of the second bidirectional lead screw 2109, allowing the rotation of the second bidirectional lead screw 2109 to move the two third nuts 2110 closer together or further apart. A fifth connecting rod 2111 is hinged to the top of the third nut 2110 via a hinge seat, allowing the fifth connecting rod 2111 to swing on the third nut 2110. The end of the fifth connecting rod 2111 away from the third nut 2110 is hinged to the inner wall of the fifth groove 2112, allowing the fifth connecting rod 2111 to swing within the fifth groove 2112. A fifth bevel gear 2104 is drively connected to the first lead screw 2105, allowing the rotation of the fifth bevel gear 2104 to drive the rotation of the first lead screw 2105.

One end of the fourth link 2107, away from the second nut 2106, is hinged to the inner wall of the fourth groove 2108, allowing the fourth link 2107 to swing within the fourth groove 2108.

[0041] In one specific embodiment of the present invention, a first groove 2003 is provided on the top of the vehicle body 1001 near the first baffle 2001, and a second groove 2004 is provided on the top of the first baffle 2001 near the second baffle 2002. The shape of the first baffle 2001 fits the shape of the first groove 2003, and the shape of the second groove 2004 fits the shape of the second baffle 2002. A third groove 2005 is provided on the top of the first groove 2003 and the second groove 2004, respectively. The third groove 2005 communicates with the inner cavity of the vehicle body 1001, and the third nut 2110 is slidably connected to the third groove 2005. A buckle 1003 is provided on one side of one vehicle body 1001, and a telescopic rod 1002 is hinged on the side of the other vehicle body 1001 away from the buckle 1003.

[0042] During operation, the third nut 2110 is slidably connected to the third groove 2005, allowing the third nut 2110 to slide within the third groove 2005. A telescopic rod 1002 is hinged to the side of the vehicle body 1001 away from the buckle 1003, allowing the telescopic rod 1002 to swing on the vehicle body 1001.

[0043] The specific workflow is as follows: By default, the two vehicle bodies 1001 fold together via hinges and are locked together via buckles 1003. First, the telescopic rod 1002 is swung to one side of the vehicle body 1001, then the buckles 1003 are opened, and the two vehicle bodies 1001 unfold together. Then, the first stepper motor 1115 is activated. The rotation of the first stepper motor 1115 drives the second bevel gear 1114 to rotate, which in turn drives the first bevel gear 1113 to rotate. The rotation of the first bevel gear 1113 drives the first double-acting lead screw to rotate, which in turn causes the two first nuts 1104 to move closer or further apart. The movement of the first nuts 1104 causes the third link 1109 to swing, which in turn causes the fixed plate 1110, the wheel 1111, and the first link 1107 to swing, causing the wheel 1111 to swing downwards, thus allowing the wheel 1111 to contact the ground and move freely. Since the first link 1107 and the second link 1108 are parallel to each other, the fixed plate 1110 and the wheel 1111 are always parallel to the ground. Then, the second stepper motor 2101 is started. The rotation of the second stepper motor 2101 drives the third bevel gear 2102 to rotate, which in turn drives the fourth bevel gear 2103 to rotate. The rotation of the fourth bevel gear 2103 drives the second bidirectional lead screw 2109 to rotate. The rotation of the second bidirectional lead screw 2109 causes the two third lead screw nuts 2110 to move closer or further apart. The movement of the third lead screw nuts 2110 causes the fifth connecting rod 2111 and the first baffle 2001 to swing. The rotation of the fourth bevel gear 2103 drives the fifth bevel gear 2104 to rotate, which in turn drives the first lead screw 2105 to rotate. The rotation of the first lead screw 2105 causes the second lead screw nut 2106 to move, which in turn causes the fourth connecting rod 2107 and the second baffle 2002 to swing. Thus, the folding and unfolding of the first baffle 2001 and the second baffle 2002 can be controlled by controlling the second stepper motor 2101.
