TECHNICAL FIELD

[0001] The utility model relates to the technical field of logistics conveying, especially relates to an unmanned logistics carrier. BACKGROUND

[0002] The existing logistics transport vehicle adopts a fixed transport plate structure, the size of the cargo compartment cannot be flexibly adjusted according to the volume of goods, especially when transporting special-shaped or large-size goods, the limitation of the fixed structure leads to reduced loading efficiency, and the goods are prone to deviation or damage due to lack of effective protection, in addition, although some transport vehicles realize the expansion of the splicing plate through mechanical locks or clamping grooves, there are problems such as poor connection stability and complicated disassembly and assembly, which are difficult to meet the high-frequency logistics operation demand.

[0003] In the current design, the connection between the splicing plate and the vehicle body mainly relies on physical insertion or bolt fixation, such mode is prone to loosening due to vibration in dynamic transportation, and frequent manual reinforcement is required. At the same time, the traditional counterweight mechanism mainly adopts fixed counterweight blocks, which cannot balance the tilting of the vehicle body caused by uneven distribution of goods in real time, affecting the stability of automatic driving.

[0004] Therefore, it is necessary to provide a new unmanned logistics carrier to solve the above technical problems. CONTENT OF THE UTILITY MODEL

[0007] Preferably, two symmetrically distributed distance sensors are fixedly installed on the left and right sides of the vehicle body, and warning lights are fixedly connected to the left and right sides of the vehicle body, and the warning lights are electrically connected with the distance sensors.

[0008] Preferably, electromagnets are fixedly connected around the plug-in grooves on the front and rear sides of the transport plate, the splicing plate contains ferromagnetic material and is magnetically adsorbed on the transport plate through the electromagnets.

[0009] Preferably, antiskid rubber pads are fixedly connected to the upper surfaces of the splicing plate and the transport plate.

[0010] Preferably, the counterweight mechanism includes a slide rail and a counterweight block, and slide rails are fixedly connected to both the left and right sides of the transport plate, with a counterweight block slidably connected on the slide rail.

[0011] Preferably, a handle is fixedly connected to the outer surface of the counterweight.

[0012] Preferably, the edge protection mechanism includes a shielding rod and a locking block. Two symmetrically distributed shielding rods are rotatably connected to both the left and right sides of the splicing plate, and the outer side of the shielding rod is threaded with a locking block for fixing.

[0013] Preferably, omnidirectional wheels are fixedly installed at all four corners of the bottom of the vehicle body.

[0014] Compared with related technologies, the unmanned logistics transport vehicle provided by this utility model has the following beneficial effects:

[0015] 1. In this utility model, the transport plate serves as the core load-bearing platform. The left and right sides are integrated with slide rails and counterweights to form a dynamic balance system. When the center of gravity of the cargo shifts, the operator can manually hold the handle on the outer surface of the counterweight and slide it laterally along the slide rail. By adjusting the symmetrical distribution of the weight of the counterweight and the cargo, the tilting torque of the vehicle body can be offset in real time, avoiding the risk of vehicle body rollover due to uneven load and improving the safety performance of the device.

[0016] 2. This utility model is equipped with an assembly and splicing mechanism. The transport plate forms a mechanical connection base with the splicing plate on one side through the evenly distributed insertion slots on the front and rear sides. The insertion plate is inserted into the insertion slot to achieve lateral positioning. At the same time, the electromagnets fixedly connected around the insertion slots of the transport plate generate a strong magnetic attraction force with the splicing plate containing ferromagnetic material. The dual effect ensures the rigid connection between the splicing plate and the transport plate, which not only avoids the risk of the splicing plate falling off due to transportation bumps, but also simplifies the manual disassembly and assembly steps. The upper surfaces of the splicing plate and the transport plate are covered with anti-slip rubber pads to prevent the goods from sliding by increasing the friction coefficient of the contact surface.
