Problems solved by technology

[0002] Although the logistics vehicle with the triangular wheel system has the function of going up the steps; however, when encountering a small section with a steep slope, it is easy to cause insufficient power due to the excessive inclination of the frame, so that the function of quickly climbing the steps cannot be realized; in addition, The wheelbase of the triangular wheel train on the existing logistics vehicle cannot be adjusted automatically, so it cannot adapt to steps of different sizes

Embodiment 1

[0035] Such as figure 1 , 2 As shown in and 3, a stair-climbing logistics vehicle with the ability to lift the rear end includes a vehicle frame 1, a traveling power module 2, a stair-climbing power module 3 and a rear wheel lifting foot module 4. The vehicle frame 1 includes a front support plate 1-1, a rear support plate 1-2 and locking pins. The top of the front support plate 1-1 is provided with two square core rods; the top of the rear support plate 1-2 is provided with two square casings; a locking hole; the outer end of one side wall of the square core rod is provided with a locking pin. The locking pin can be retracted. Two square core rods extend into two square sleeves respectively to form a sliding pair. The locking pin on the square core rod is snapped into one of the locking holes of the corresponding square sleeve. The length of the vehicle frame 1 can be adjusted by switching the locking pins and fixing them with different locking holes. A handle is instal...

Embodiment 2

[0058] The difference between this embodiment and Embodiment 1 is that no locking drive assembly is provided; both the inner and outer locking mechanisms and the outer disc locking mechanism are replaced by magnetic powder clutches. That is, the inner turntable 3-6 is connected with the outer turntable 3-5 by a magnetic powder clutch; the outer turntable 3-5 is connected with the vehicle frame 1 by a magnetic powder clutch; thereby realizing the synchronous rotation of the inner turntable 3-6 and the outer turntable 3-5 (using For climbing stairs) and the independent rotation of the inner turntable 3-6.

Embodiment 3

[0060] In this embodiment, on the basis of Embodiment 1 or 2, a grating disc and a photoelectric sensor are added to the telescopic triangular gear train; The relative rotation angle of the outer turntable 3-5 and the inner turntable 3-6, thereby judging the current front wheel track.

Abstract

The invention discloses a stair-climbing logistics vehicle with tail end lifting capability and a stair-climbing method thereof. The invention relates to a stair-climbing logistics vehicle with the ability to lift the rear end, comprising a vehicle frame, a stair-climbing power module and a rear wheel-assisted foot-lifting module. The rear wheel lifting foot module is installed at the rear end of the vehicle frame. The stair-climbing power module is installed on the head end of the vehicle frame. The stair-climbing power module includes two triangular gear trains respectively arranged on both sides of the head end of the vehicle frame. Three front wheels arranged in an equilateral triangle are arranged in the triangular gear train. The rear wheel-assisted foot-lifting module includes a fixed shaft, a foot-lifting drive assembly and an outer support assembly. Described fixed axle is fixed on the tail end of vehicle frame. The outer support assembly includes a crank case, a connecting rod, an outer support gear set, a support rod and a slide rail. The rear wheel lift-assisted foot module in the present invention can support the rear end of the logistics vehicle, thereby reducing the inclination angle of the logistics vehicle when the logistics vehicle encounters obstacles on the steps, and improving the climbing ability of the logistics vehicle.

Description

technical field [0001] The invention belongs to the technical field, and in particular relates to a stair-climbing logistics vehicle with tail lifting capability and a stair-climbing method thereof. Background technique [0002] Although the logistics vehicle with the triangular wheel system has the function of going up the steps; however, when encountering a small section with a steep slope, it is easy to cause insufficient power due to the excessive inclination of the frame, so that the function of quickly climbing the steps cannot be realized; in addition, The track of the wheels in the triangular wheel train on the existing logistics vehicle cannot be automatically adjusted, so it cannot adapt to steps of different sizes. Contents of the invention [0003] The object of the present invention is to provide a stair-climbing logistics vehicle with tail lifting capability and a stair-climbing method thereof. [0004] The invention relates to a stair-climbing logistics veh...
