The Design of length of electro-tricycle frame of the present utility model is that 1200mm-1300mm, width are 650mm-690mm, preferred length 1300mm, width 690mm.
In addition, this vehicle frame front portion can fixedly mount bicycle basket, at the vehicle frame rear portion, under-seat can install storage tank.The utility model battery carrier is placed on below, vehicle frame middle part, takes full advantage of the space structure modeling characteristic of vehicle frame, can reduce like this car load center of gravity, reasonable distribution complete vehicle weight, thereby reach the effect that car load is ridden steadily, is difficult for rollover.
Single seat electro-tricycle frame of the present utility model mainly contains following characteristics:
1, main car frame structure: adopt the steel pipe space structure entirely to carry light-weight design; and adopt numerically controlled steel pipe to bend molding process; be welded through automatic gas shielded welding by the light high-intensity steel pipe; shock resistance and absorb energy; realize that vehicle frame namely carries and lightweight entirely, weight meets country to the requirement of battery-driven car weight.
2, shock mitigation system: existing electro-tricycle front fork hydraulic pressure cushion technique is adopted in the front fork damping; The rear-mounted shock mitigation system adopts stand alone type to hang shock-damping structure, and each trailing wheel connects by two suspension arms, then is connected with main car frame by rear damping spring, thereby realization two trailing wheel independence dampings in the situation of jolting, drives steady comfortable effect.
3, vehicle frame size: when Mechanical Builds designed, that considers the one-seater electric three-wheel vehicle deposited and tackle traffic jam issue, finally determined: the length of vehicle frame is that 1200mm-1300mm, width are 650mm-690mm, preferred length 1300mm, width 690mm.Like this, car load has small and exquisite advantage flexibly and deposits conveniently when traffic congestion, can directly sail elevator into, also can directly enter in storage cellar or room.
4, storage space: the one-seater electric three-wheel vehicle is often given people's narrow space, unpractical sensation, the utility model takes full advantage of the space structure modeling characteristic of vehicle frame, at the anterior bicycle basket of installing of vehicle frame, at the vehicle frame rear portion, under-seat can install storage tank, the practicality of vehicle improves greatly.
5, battery carrier position: battery carrier is placed on stretcher below, vehicle frame middle part, can reduce like this car load center of gravity, reasonable distribution complete vehicle weight, thereby reach the effect that car load is ridden steadily, is difficult for rollover.
The beneficial effects of the utility model are: vehicle frame adopts tube material, three-D space structure moulded, front-wheel, trailing wheel all adopt shock mitigation system, vehicle frame lightweight and full carrying, the car load riding safety is comfortable, for the electro-tricycle industry provides a kind of new body frame structure for automotive styling design thinking, change the outmoded Mechanical Builds of conventional electric tricycle frame.
