Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of intelligent logistics transfer trolley, and particularly relates to an automatic following logistics transfer trolley with hidden wiring. BACKGROUND

[0002] Factories, logistics companies and other places usually use trolleys as carrying tools to realize position movement by manpower. In order to improve the operation efficiency of transferring objects by using trolleys, logistics trolleys driven by motors and capable of automatically following personnel appear.

[0003] As disclosed in Chinese patent CN202121123443.1, an intelligent trolley includes a load plate assembly, a handle assembly installed on one side of the load plate assembly, a wheeled walking mechanism arranged on the bottom surface of the load plate assembly and used for automatically driving the intelligent trolley to move, a power battery assembly connected with the wheeled walking mechanism and used for driving the wheeled walking mechanism to move, a following module arranged on the handle assembly, the following module including a following module, a scanning label and a positioning label, the following module being configured to generate the positioning label in communication with the following module by a user scanning the label through a mobile terminal, and the following module being used for detecting the relative position of the handle assembly and the positioning label, and a controller connected with the following module and the power battery assembly respectively. The intelligent trolley is powered by electricity and can follow the pace of a person to travel, which is more intelligent, and the user can achieve the purpose of freeing hands and reducing work intensity when carrying objects, thereby improving work efficiency.

[0004] In the existing logistics transfer trolley capable of automatic following, in order to facilitate operation, an input device for control instruction is usually arranged at the handle of the trolley, such as a control switch or the following module in Chinese patent CN202121123443.1. In order to avoid affecting the transportation of products, the power battery and other devices are usually arranged below the load platform. The instruction input device at the handle of the transfer trolley needs to be connected to the battery pack and other devices below the load platform through a cable.

[0005] In order to prevent scratches and entanglements between the goods on the logistics trolley and the cable above the load platform, and avoid damage to the cable by the transported goods, the cable is usually tied on the handle by a cable tie. However, since the handle on the load platform is usually designed to be foldable, and the length of the cable below the load platform is fixed, if the cable above the load platform is tied and fixed on the handle and the cable is taut, although the cable can be effectively hidden and protected from damage, when the handle is folded, the cable cannot be stretched, and forcibly folding the handle will cause the cable to break. If the cable above the load platform is tied and fixed on the handle and the cable is not taut, although the handle can be normally folded, the cable cannot be effectively hidden and protected from damage by the transported goods.

[0040] An auxiliary buckle 24 is arranged on the vertical plate 22, and the cable 31 is buckled in the auxiliary buckle 24. The auxiliary buckle 24 has the same structure as the wiring buckle 54, and the auxiliary buckle 24 assists the wire blocking rod 52 in supporting the horizontal wiring of the cable 31, so that the cable 31 can be kept in a tight state when the handrail 2 is not folded.

[0041] The stand plate 22 is provided with a mounting seat 25 for mounting an auxiliary buckle 24. The mounting seat 25 comprises two parallel mounting plates. The auxiliary buckle 24 is provided with a connecting rod 241 at the back thereof. The connecting rod 241 is provided with symmetrically arranged convex blocks 242 at both sides thereof. The cross section of the convex blocks 242 is in the shape of a circular arc. The convex blocks 242 are clamped in the circular through holes of the mounting plates. The auxiliary buckle 24 is buckled with the mounting plates of the mounting seat 25 through the convex blocks 242 at the back of the connecting rod 241. The connecting rod 241 is easily separated from the mounting seat 25. In this way, when the handrail is folded, the cable 31 is prevented from being easily separated from the auxiliary buckle 24, and the auxiliary buckle 24 is directly separated from the stand plate 22, so as to avoid affecting the cable 31 to return to a relaxed state.

[0042] The first opening 544 is towards the side away from the controller 3. The cable 31 is not easily separated from the wiring buckle 54, and the wiring buckle 54 can effectively position and tighten the cable 31.

[0043] The width of the connecting head 541 is equal to the width of the second strip-shaped through hole 212. The locking plate 542 is a circular plate. The diameter of the locking plate 542 is equal to the inner diameter of the support pipe 21. The wiring buckle 54 can slide smoothly along the second strip-shaped through hole 212.

[0044] The line blocking rod 52 is a circular rod, which avoids scratching the cable 31 when the cable 31 passes around.

[0045] The cable 31 is provided with a wire harness sleeve on the outside, which effectively protects the cable 31. In order to prevent contamination, a wire harness sleeve with a dirt-proof coating can also be used.

[0046] Working principle: in the conventional use state of the logistics transfer vehicle, the cable 31 on the side of the controller 3 is buckled in the wiring buckle 54 after passing around the line blocking rod 52, and then the cable 31 passes through the loading platform 1 and extends below the loading platform 1, thereby connecting devices such as batteries. The position of the cable 31 below the loading platform 1 is fixed. At this time, the first electromagnet 53 and the second electromagnet 55 are in the energized state. The line blocking rod 52 is fixed by being attracted by the first electromagnet 53. The line blocking rod 52 is perpendicular to the stand plate 22. The wiring buckle 54 is located at the top end of the second strip-shaped through hole 212. The spring 56 is in the compressed state. The line blocking rod 52 and the wiring buckle 54 cooperate to tighten the cable 31, and make the cable 31 arranged along the lower edge of the stand plate 22 and the rear side of the support pipe 21, thereby realizing hidden wiring of the cable 31.

[0047] When the folding handrail 2 is folded on the cargo platform 1 of the logistics transfer vehicle, the inertia sensor in the connecting block 4 of the handrail 2 can detect whether the handrail 2 is rotated counterclockwise to be folded or rotated clockwise to be opened. When the inertia sensor detects that the handrail 2 is rotated counterclockwise to be folded (i.e. folded), the processor controls the first electromagnet 53 and the second electromagnet 55 to be in a power-off state, the blocking wire rod 52 is no longer attracted and fixed by the first electromagnet 53, the blocking wire rod 52 cannot effectively block the wire cable 31, and at the same time, the second electromagnet 55 no longer attracts the iron sheet 543, so that the wiring buckle 54 is lowered (moves away from the vertical plate 22) under the action of the spring 56 and the gravity of the wire cable 31, so that the wire cable 31 changes from a tight state to a relaxed state, and the folding of the handrail does not cause damage to the wire cable 31.

[0048] The hidden wiring assembly 5 automatically releases the tight state of the wire cable 31 when the handrail 2 is folded, avoiding damage to the wire cable 31. When the handrail 2 is used again and rotated to be opened, the processor controls the first electromagnet 53 and the second electromagnet 55 to be in a power-on state, and manually resets the blocking wire rod 52 and the wiring buckle 54, so that the wire cable 31 is hidden again.

[0049] The above is only a preferred specific embodiment of the present application, but the protection scope of the present application is not limited thereto, any person skilled in the art can make equivalent replacement or change according to the technical solution and the inventive concept of the present application within the technical range disclosed by the present application, which should be covered within the protection scope of the present application.
