Problems solved by technology

Although a logistics vehicle with a triangular wheel train has the function of going up steps; but because the wheel track in the triangular wheel train cannot be automatically adjusted, it cannot adapt to steps of different sizes; specifically, the wheel track in the triangular wheel train If it is too small, the wheels in the triangular gear train will turn up until they touch the vertical surface of the current step, making it impossible to climb up the steps; Until the vertical surface of the current step on the last level makes it impossible to climb the steps; therefore, it is necessary to design a logistics vehicle that can maintain the regular triangle arrangement of the triangular wheel train wheels and realize the wheelbase adjustment of the triangular wheel train

Embodiment 1

[0031] like figure 1 and 2 As shown, a stair-climbing logistics vehicle with an adjustable triangular wheel train includes a vehicle frame 1, a rear wheel module 2, a stair-climbing power module 3 and a controller. The vehicle frame 1 includes a front support frame 1-1, a rear support frame 1-2 and locking pins. The top of the front support frame 1-1 is provided with two square core rods; the top of the rear support frame 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 installed on the top of the rear suppor...

Embodiment 2

[0048] 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 disk locking mechanism are replaced by magnetic powder clutches. That is, the inner turntable 3-6 is connected with the outer turntable 3-5 through a magnetic powder clutch; the outer turntable 3-5 is connected with the vehicle frame 1 through a magnetic powder clutch; thereby realizing the synchronous rotation of the inner turntable 3-6 and the outer turntable 3-5 for Independent rotation of stair climbing and inner turntable 3-6.

Embodiment 3

[0050] The difference between this embodiment and Embodiment 1 is: there is no locking drive assembly and outer disk locking mechanism; 1 locks, but uses gravity to automatically keep each telescoping triangular train with two front wheels supported on the ground.

Abstract

The invention discloses a stair-climbing logistics vehicle with an adjustable triangular gear train and a stair-climbing method thereof. Existing logistics vehicles with triangular wheel trains cannot adapt to steps of different sizes. The invention relates to a stair-climbing logistics vehicle with an adjustable triangular wheel train, comprising a vehicle frame, a rear wheel module and a stair-climbing power module. The stair-climbing power module includes a stair-climbing adjustment drive assembly and two telescopic triangular gear trains. The telescopic triangular gear train includes a front wheel, a slide block, a damping rod, an outer turntable, an inner turntable and an inner and outer locking mechanism. The inner ends of the three damping rods are all hinged with the outer edge of the outer turntable. Slide blocks are slidably connected to the three damping rods. Three connecting rods are fixed on the outer edge of the inner turntable. The three connecting rods and the three slide blocks constitute the revolving pairs respectively. The telescopic triangular gear train wheel in the present invention can realize the adjustment of the wheelbase in the triangular gear train through the relative movement of the outer turntable and the inner turntable, so that the triangular gear train can adapt to steps of different sizes.

Description

technical field [0001] The invention belongs to the technical field, and in particular relates to a stair-climbing logistics vehicle with an adjustable triangular gear train and a stair-climbing method thereof. Background technique [0002] Most of the equipment for assisting climbing stairs and carrying goods at the present stage requires manpower. Although a logistics vehicle with a triangular wheel train has the function of going up steps; but because the wheel track in the triangular wheel train cannot be automatically adjusted, it cannot adapt to steps of different sizes; specifically, the wheel track in the triangular wheel train If it is too small, the wheels in the triangular gear train will turn up until they touch the vertical surface of the current step, making it impossible to climb up the steps; To resist the vertical surface of the current step of the rear stage, it is impossible to climb up the steps; therefore, it is necessary to design a logistics vehicle t...
