An alarm light 24 and a single-chip microcomputer main control board 25 are provided at the front position of the courier vehicle body 1, and the single-chip microcomputer main control board 25 is electrically connected to the alarm light 24.

[0028] Furthermore, the placement component 21 includes a tailgate 211 fixedly connected to the rear of the express vehicle body 1, one side of the tailgate 211 is fixedly connected to a reinforced hinge 2111 and an elastic rope 2112, one end of the elastic rope 2112 is fixedly connected to a fall-off detection clip 21121, the outer side of the tailgate 211 is fixedly connected to a mounting track 212, one side of the mounting track 212 is provided with a drill hole 2121, the fall-off detection clip 21121 is electrically connected to the microcontroller main control board 25 through the tailgate 211 and the interior of the express vehicle body 1, and the surface of the tailgate 211 is covered with a protective film. It is covered with a plastic coating, and its equidistant drilled holes 2121 can be used to install support rods 231, ensuring that different models of trolley bodies 221 can be mounted on the express vehicle body 1. The presence of the plastic coating can not only prevent rust, but also prevent the trolley body 221 from colliding with the express vehicle body 1 and producing abnormal noise. The detachment detection clip 21121 connected by the elastic rope 2112 can be clamped on the handle bar 22111 in the trolley body 221, so that if the trolley body 221 accidentally falls during the forming process, the driver can detect and deal with it in time through the warning light 24 at the front instrument panel position.

[0029] Furthermore, the trolley component 22 includes a trolley body 221 arranged on the outside of the mounting rail 212, a plate 2211 is fixedly connected to one side of the trolley body 221, one end of the plate 2211 is rotatably connected to a handle bar 22111, and holes 2212 are evenly opened through one side of the trolley body 221.

[0030] Furthermore, the limiting component 23 includes a support rod 231 fixedly connected to the outside of the mounting rail 212, one end of the support rod 231 is riveted with a foldable self-locking hinge 232, one end of the foldable self-locking hinge 232 is riveted with a limiting rod 233, the support rod 231 passes through the interior of the hole 2212, the surface of the limiting rod 233 is covered with a plastic coating, the foldable self-locking hinge 232 is rust-proofed by electroplating, the model of the foldable self-locking hinge 232 is CN-ZD006, and the foldable self-locking hinge 232 is equipped with an extended unlocking wrench to ensure that the limit rod 233 can firmly clamp the flatbed cart when locked. When unlocking is required, the courier only needs to turn the four unlocking wrenches to easily remove the flatbed cart. The support rod 231 is located on the diagonal of the mounting track 212, and the limit rod 233 is directed to the four corners to ensure that the design of the four-corner holes 2212 allows the trolley body 221 to be safely mounted. The foldable self-locking hinge 232 is designed with an unlocking lever and it is lengthened to improve its ease of operation.

[0031] like Figure 4 As shown, the reinforcing component 26 includes a chain 261 fixedly connected to one end of the limiting rod 233, one end of the chain 261 is fixedly connected to a round block 2611, the outer surface of the round block 2611 is fixedly connected to a clamping block 26111, one end of the round block 2611 is fixedly connected to a pull rod 26112, the clamping block 26111 is used to limit the round block 2611, and the pull rod 26112 facilitates moving the round block 2611 inside the installation track 212 from the outside.

[0032] like Figure 5 As shown, a circular groove 262 is provided on one side of the mounting rail 212, and a sliding groove 2621 and an annular groove 2622 are provided on the inner wall of the circular groove 262, the circular groove 262 is slidingly connected to the round block 2611, the sliding groove 2621 is slidingly connected to the clamping block 26111, and the annular groove 2622 is rotatably connected to the clamping block 26111.

[0033] The working principle and usage of the present invention are as follows: When the trolley body 221 needs to be placed, the staff first needs to align the four sets of holes 2212 of the trolley body 221 with the support rod 231, and make the support rod 231 pass through the holes 2212, then bend the exposed end of the support rod 231, that is, the limit rod 233, to the self-locking position, thus completing the quick mounting of the trolley body 221, and wrap the signal line from the tailgate 211 of the express vehicle body 1 through the elastic rope 2112 and connect it to the shedding detection clip 21121, and the shedding detection clip 21121 During operation, the detection clip 21121 is clamped on the handlebar 22111 in the trolley body 221. The signal line is routed inside the body of the vehicle and connected to the microcontroller main control board 25 next to the front display. When the trolley body 221 accidentally separates from the support rod 231, the detachment detection clip 21121 separates from the handlebar 22111, thereby causing the alarm light 24 to output an external warning through the microcontroller main control board 25, immediately notifying the driver. The entire device adopts a shock-proof plastic coating and electroplating anti-rust treatment, which not only protects the components but also reduces operating noise. At the same time, the integrated anti-theft lock further ensures the safety of the cargo.

[0034] However, when the trolley body 221 is limited to the support rod 231 by the limiting rod 233, when the express trolley body 1 brakes suddenly or is hit, the impact force on the limiting rod 233 is too large, so that the limiting rod 233 still has an unexpected folding and bending. In this case, when the limiting rod 233 is folded and bent to 90 degrees, the pull rod 26112 is pulled to straighten the chain 261, and the block 26111 in the round block 2611 can be pulled. Align the slide groove 2621 and push it to place it, then rotate the pull rod 26112 to drive the block 26111 to rotate along the annular groove 2622, so that the block 26111 is separated from the slide groove 2621. At this time, the round block 2611 can be prevented from escaping from the inside of the circular groove 262, and because the chain 261 is in a straight state, it can further prevent the hole 2212 from separating from the support rod 231, that is, further prevent the trolley body 221 from escaping from the support rod 231.

[0035] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
