Description

Connecting structure of driving device in transverse pipe

Technical Field

A connecting structure of a driving device in a transverse pipe and a bicycle are particularly used in the fields of bicycles, mopeds, bicycle models and the like.

Background

In the design of an unmanned bicycle, both a steering driving design with a built-in transverse pipe and a driving device design structure with a built-in flywheel of a transverse pipe require a stable and simple driving device installation and connection structure, and publication No. 2019203500021 discloses a bicycle steering device, wherein the steering driving device is installed on a first support piece or a second support piece, a motor of the steering driving device is installed in a vacancy of the support piece to play a role of supporting and fixing, but a light bicycle has volume requirements on the outer diameter of the transverse pipe in terms of beauty and cost, so that the inner space of the transverse pipe is limited, the required steering motor with larger torsion has larger outer diameter, and the gap between the motor and the inner diameter of the transverse pipe is smaller, so that the edge of a connecting guide groove near the vacancy of the support piece is very thin, the vacancy of the support piece is easy to bend, and the installation of the support piece on the guide groove is difficult easily caused.

SUMMERY OF THE UTILITY MODEL

A connecting structure of a driving device in a transverse pipe and a bicycle comprise the transverse pipe, a supporting piece and the driving device; it is characterized in that the supporting piece is connected with the inner guide groove of the transverse pipe; the supporting part is provided with a vertical connecting plate or a connecting piece which is connected with the supporting part and the driving device. The outer diameter of the driving device is less than or equal to the inner diameter of the transverse pipe, and the bottom of the driving device or the sleeve is sleeved on the driving device and then supported by the inner diameter of the transverse pipe.

The connecting piece has the advantages that the connecting piece is only used for connecting the supporting piece and the driving device, the driving device is directly or is supported by the inner diameter of the transverse pipe after being sleeved with the sleeve, the supporting piece is prevented from being bent, the cost is saved, the stability of the supporting piece is improved, and the driving device which is most suitable for assembling the inner volume of the transverse pipe is utilized to the maximum extent.

The advantage is that the connecting piece or plate is integral with the support, and can be assembled separately or fastened together.

Its advantage is that the connecting part or connecting plate is narrower than the supporting part, so it does not influence the supporting part and the connecting part to be completely placed in the transverse tube.

The motor has the advantages that when the clearance between the outer diameter of the motor and the transverse pipe is large, the outer diameter of the driving device is additionally provided with the independent sleeve for supporting, and the small motor and the large motor can be flexibly matched by using the same supporting piece matched with the sleeve.

Its advantage lies in support piece and connecting piece integral type structure, and is lower than split type cost, and the sheet metal component manufacture process is simplified, avoids the structure of independent connecting piece to need the uneven structure of milling machine processing. The support body and the edge of the connector portion are cut out in a plane directly by laser and then bent into a vertical configuration. Or two flat plates can be welded.

The connecting piece has the advantages that the arc-shaped outer diameter of the connecting piece is in contact with the inner diameter of the transverse pipe, so that the connecting piece is limited by the inner diameter of the transverse pipe to move vertically.

The advantage is that the support body and the drive body are on both sides of the connector.
