electric bicycle

Abstract

The invention discloses a novel two-wheel electric bicycle. The novel two-wheel electric bicycle mainly comprises a novel bicycle frame, a novel battery box and the like, wherein a riser of the bicycle frame is separated from a middle joint; an upper section of the riser is suspended; a lower pipe of the bicycle frame takes a shape of lower and rear arcs; the rear part of the lower pipe of the bicycle frame is extended and bent to be tangent to a splash guard of a wheel; the rear end of the lower pipe of the bicycle frame is abutted with the riser; the battery box is positioned in the middle of the bicycle, namely below a saddle and the riser; the middle joint is arranged in a space encircled by the battery box and the lower pipe; a guiding internal slot is formed in the upper end of the battery box; a guiding lug boss is arranged at the lower end of an upper location guide plate; the guiding internal slot can be matched with the guiding lug boss in a sliding way; the battery box can be led in or out along the sliding direction; a location slot is formed below the front part of the battery box and is matched with a location lug boss on the upper part of a front location plate; thelocation lug boss is arranged below the middle part of the battery box and is matched with the location slot on the lower part of a lower location guide plate; the main surface of the location guide plate is in sliding fit with the lower front surface of the battery box; a space formed by combining the battery box, the upper location guide plate, the front location plate and the lower location guide plate is fully sealed; and the formed outer arc line is coordinated and matched with the arc surface of the lower pipe.

Description

technical field [0001] The invention relates to a new two-wheeled electric bicycle, especially a two-wheeled electric bicycle with a new frame, a new battery box, a new battery box placement position, a new battery box pick-and-place method and a positioning structure, and a new middle double bracket. Background technique [0002] At present, there are many kinds and types of known electric bicycles, but most of them are the same or similar. These bicycles have many advantages respectively, but there are also some shortcomings respectively. A certain impact; the car with the rear battery box is now the mainstream model in the market, but it increases the load on the rear wheel, and needs to be equipped with a saddle turning mechanism. The battery box needs to be lifted very high to take out the battery box; the position and structure of the bracket are unreasonable, etc. . Contents of the invention [0003] In order to overcome the deficiencies of existing electric bicycl...
