Abstract

The invention discloses a two-wheeled electric bicycle, which mainly comprises a frame, a battery box, a battery box positioning and locking mechanism and standard components. The arc battery box and an arc frame riser are adopted, and the radian of the arcs is matched with and corresponds to that of a back wheel; a bottom box is arranged on the lower part of the battery box, and can position the lower end of the battery box; the upper part of the battery box is provided with a front positioning table and a rear positioning table, and the frame is provided with a front positioning groove and a rear positioning groove for the battery box on corresponding parts; the positioning tables and the positioning grooves for the battery box can position the upper part of the battery box; the battery box positioning height is low, and the positioning parts can exert the effect when the battery box is about to be positioned in place; in other states, an enough gap is formed between the battery box and each component of the frame so as to ensure that the battery box is freely, flexibly and easily taken and place; and when batteries are placed, the batteries are not required to be accurately aligned with an inlet, a saddle is not required to be overturned for providing a space, and a battery box bolt on the battery box is directly inserted into a frame riser lockhole to lock the battery box.

Description

Electrical Bicycle

Technical field

The present invention relates to a kind of novel two-wheeled electric bicycle, especially adopt arc battery case and new-type battery case to pick and place the two-wheeled electric bicycle of method and location structure.

Background technology

At present, known Electrical Bicycle kind, type are a lot, the rear-mounted car of battery case is a market mainstream vehicle, these cars all have many advantages separately, but also come with some shortcomings separately, for example: the rear-mounted car of battery case, battery case guide plate detent mechanism is arranged, also want accurate aligned inlet when putting battery case, when taking out battery case, need overcome battery case gravity and add the guide plate friction force, saddle need be established switching mechanism and step down for the fetching battery box, and the cost height, operation is loaded down with trivial details, battery case guide plate location division is fragile, saddle easily rocks etc.

Summary of the invention

In order to overcome the deficiency of existing Electrical Bicycle, the invention provides a kind of Electrical Bicycle, this car adopts arc battery case, arc seat tube, new-type battery case to pick and place method and location structure, does not need the saddle upset mechanism that steps down, and the battery case dead bolt directly inserts locking in the seat tube lockhole.

The technical solution adopted for the present invention to solve the technical problems is: adopt arc battery case, arc seat tube, above-mentioned arc radian is coordinated mutually, is echoed with trailing wheel.

End box is arranged at the battery case bottom, box is except that opened upper end at the end, other direction sealing, battery case location vertical plane groove is arranged at box bottom, the end, top has and makes things convenient for battery case to enter the wide cambered surface of guiding, end box is fixed at the bottom of the vehicle frame on the box locating plate, and the box locating plate is connected with left and right sides vehicle frame chain stay at the bottom of the vehicle frame, and end box can be with location down all around, battery case lower end.

Prelocalization platform and back positioning table are arranged at battery case top, battery case prelocalization groove is housed on the seat tube of corresponding site, positioning groove behind the battery case is housed on the vehicle frame positioning groove locating plate of corresponding site, and the forward and backward positioning groove of battery case can be located front, rear, left and right, battery case top.

The battery case lock is arranged on the battery case, battery case dead bolt axis is on the center reference face of vehicle frame, and over against the lockhole at seat tube rear portion, the battery case dead bolt directly inserts in the seat tube lockhole battery case is locked forward in the dead bolt end, stop battery case to move up and down, prevent from battery case is taken out.

Place, the location of battery case is highly less, and the place, location just can play a role when battery case will be put into, under other situation, between each part of battery case and vehicle frame enough gaps is arranged, with guarantee freedom, flexible, make things convenient for the fetching battery box,

The invention has the beneficial effects as follows, created the arc battery case, new-type battery case picks and places method and location structure, do not need the saddle upset mechanism that steps down, do not need battery case guide plate detent mechanism, do not need when putting battery case accurately to inlet, need not overcome the guide plate friction force when taking out battery case, locations is not fragile, and saddle can not rock.

This car novelty, uniqueness, lucid and lively, smooth, attractive in appearance, generous, in light weight, cost is low, fault is low, the life-span is long, easy to use, have distinct novelty, significant practicality, outstanding creativeness.
