Postal express delivery vehicle with anti-rollover vehicle body mechanism

Abstract

The invention discloses a postal express delivery vehicle with an anti-rollover vehicle body mechanism. The postal express delivery vehicle comprises a vehicle frame, a carrying box, a front wheel andtwo rear wheels. The vehicle frame is formed by combining a front frame and a rear frame; a steering mechanism is arranged at a front end of the front frame, and front wheels are mounted below the steering mechanism; a pedal frame is installed on the front frame and comprises two pedal transverse rods, the middles of the two pedal transverse rods are movably hinged to the front frame, and the outer ends of the two pedal transverse rods are connected with pedal side rods; a seat bracket is arranged at the tail part of the front frame; the tail part of the seat bracket is movably hinged with the rear frame through a transverse rotating shaft; and a side-tipping steering adjusting mechanism is installed on the rear frame, the two rear wheels are installed on the two sides of the side-tippingsteering adjusting mechanism, and the carrying box is positioned above the side-tipping steering adjusting mechanism. According to the design, the vehicle frame and the wheels on the vehicle frame can be subjected to side inclination adjustment in an uneven road surface or turning process so that an influence of gravity or a centrifugal force on the vehicle body in the uneven road surface or turning process is effectively relieved, and stable driving and turning are guaranteed.

Description

technical field [0001] The invention relates to a motorized or electric carrier, in particular to a postal delivery vehicle with a rollover-proof body mechanism. Background technique [0002] Existing motorized or electric postal delivery vehicles generally adopt a full load-bearing structure for their body, and the wheels on it cannot be adjusted relative to the body. The advantage of this body structure is that it runs smoothly in a straight line. However, when the road surface is uneven or turning, the body is greatly affected by gravity or centrifugal force. If the speed is too fast, it is easy to tilt and overturn, which poses a great safety hazard. Contents of the invention [0003] In view of the above problems, the present invention has designed a postal delivery vehicle with an anti-rollover body structure, the vehicle frame and the wheels on it can be adjusted for rolling when the road surface is uneven or turning, so that the carrying box is relatively high rela...
