Embodiment 1

[0022] Example 1, such as image 3 The first connecting rod 3 constitutes a sliding structure in the vehicle frame 1, and the vehicle frame 1 and the fixed block 2 are connected in a threaded manner, and the height of the vehicle seat 6 is slid on the vehicle frame 1 by the first connecting rod 3, and the The rotation of the fixed block 2 can conveniently fix or separate the first connecting rod 3 from the vehicle frame 1, which is easy to operate and more comfortable to use;

Embodiment 2

[0023] Example 2, such as figure 2 The fourth gear 16 and the pedal 15 form a welded integrated structure, and the diameter of the longitudinal section at the center of the pedal 15 is smaller than the diameter of the second connecting rod 13, and the fourth gear 16 is driven by the pedal 15 to rotate to form a rear wheel 19 Provide power, the second connecting rod 13 and the pedal 15 are all fixed on the vehicle frame 1, and when the motor 9 drives the second gear 12 and the third gear 14 to rotate, the pedal 15 will not be driven to rotate, and the two systems are separated.

[0024] Working principle: When using the transmission device of the mid-mounted electric bicycle, first turn on the motor 9 to drive the first gear 10 to rotate, the first gear 10 drives the second gear 12 to rotate through the first conveyor belt 11, and the second gear 12 passes through the second Two connecting rods 13 are connected with the third gear 14, both drive the third gear 14 to rotate, th...

Abstract

The invention discloses an intermediate transmission device of an electric bicycle. The device comprises a bicycle frame, a motor and pedals. The bicycle frame is connected with a first connecting rodthrough a fixing block. The first connecting rod is connected with a saddle through a telescopic rod. The outer side of the telescopic rod is connected with a spring. The bicycle frame is connected with a case. A case cover is arranged on the front surface of the case. The motor is located in the case. The front side of the motor is connected with a first gear. The first gear is connected with asecond gear through a first conveyor belt. The second gear is connected with the bicycle frame through a second connecting rod. A third gear is connected between the second gear and the bicycle frame.The pedals are located on the inner side of the second connecting rod. By the adoption of the intermediate transmission device of the electric bicycle, the height of the device can be adjusted according to the height of a person, the device is used more comfortably through an arranged shock absorption device, two drive modes are used, and a storage battery can be conveniently detached.

Description

technical field [0001] The invention relates to the related technical field of electric bicycles, in particular to a transmission device of a mid-mounted electric bicycle. Background technique [0002] An electric bicycle refers to a mechatronic personal vehicle that uses a battery as an auxiliary energy source on an ordinary bicycle. The transmission device is an intermediate device that transmits the power of the power device to the working mechanism. The basic function of the transmission system is The power from the engine is transmitted to the driving wheels of the vehicle to generate driving force, so that the vehicle can run at a certain speed, but the general electric bicycles on the market cannot adjust the height of the device according to the height of the person, and there is no shock absorption facility. And the drive mode is single, and the battery is inconvenient to disassemble. Therefore, we propose a transmission device for a mid-mounted electric bicycle in ...
