Description

bicycle stem

The present invention relates to a bicycle standpipe, especially a bicycle standpipe which can improve the structural strength.

Bicycles have both transportation and sports and leisure functions. They are one of the favorite means of transportation for modern people, especially electric bicycles that can be driven by electricity. It is deeply loved by the public, and most of the existing electric bicycles are equipped with electronically controlled instruments that can be operated, controlled or switched by the rider. The electronically controlled instrument has a display screen that can display riding-related information. For the convenience of the rider to operate the electric control instrument, most of the existing electric control instruments are embedded on the vertical tube of the bicycle, such as the Chinese utility model No. 214451595, the Chinese utility model No. 216128395, and the Korean patent No. 20-20009-0003149 case or PCT Patent Publication No. 2010/128761, etc.

And as aforementioned each existing structure, when intending to assemble the electronic control instrument on the standpipe of the bicycle, an embedding port corresponding to the external dimension of the electric control instrument needs to be set earlier on the top surface of the stand pipe, and then the electric control instrument is inserted from the embedding port. The upper part is fixed in the insertion opening to complete the assembly of the electronic control instrument. However, the electronic control instrument on the existing bicycle vertical tube is assembled from top to bottom, so the size and shape of the insertion opening set on the vertical tube must be completely In line with the size and shape of the entire shape of the electronic control instrument, the area of the insertion opening on the existing standpipe is relatively large, and the structural strength of the standpipe itself will be damaged and weakened due to the large area of the insertion opening. There is indeed room for further improvement. necessary.

Therefore, the author specially developed a new type that can improve existing deficiencies through continuous research and testing in order to improve the deficiencies in the existing bicycle standpipe structure and use.

The main purpose of this new model is to provide a vertical tube for a car, which assembles the electronic control instrument in the vertical tube from front to back, so as to reduce the area of the window hole and improve the structural strength of the vertical tube. purpose.

In order to achieve the above purpose, the present invention mainly provides a bicycle standpipe, which includes an elongated standpipe body. A handle through hole for assembling a bicycle handle, and a front fork through hole that runs through the vertical tube body longitudinally and can be used to assemble a bicycle front fork tube is formed at the other end of the vertical tube body, and a handle through hole is formed in the vertical tube body One end is formed with an insertion hole communicating with the through hole of the handle, and a viewing window hole communicating with the interior of the standpipe body is provided on the top surface of the standpipe body.

In the bicycle standpipe, a cover for closing the insertion hole is arranged on the insertion hole.

The bicycle standpipe further includes a plurality of fixing parts that protrude into the side of the standpipe body and can be used to lock into the electric control instrument.

In the bicycle standpipe, a flange protrudes from the inner periphery of the viewing window hole.

With the above-mentioned technical means, the new model can insert the electronic control instrument into the vertical pipe body from front to back through the insertion hole, so the size of the viewing window hole on the vertical pipe body only needs to be the same as that displayed on the electronic control instrument. The size and shape of the screen can be matched, and it is not necessary to match the size and shape of the entire electronic control instrument, so the area of the window hole can be effectively reduced, and the area of the solid part of the standpipe body can be effectively reserved. To effectively enhance the structural strength of the standpipe body itself.

This model mainly provides a bicycle standpipe, please refer to Fig. 1 to Fig. 4, as can be seen from the figure, the standpipe of the present invention mainly includes an elongated standpipe body 10, and the standpipe body 10 is generally hollow One end of the standpipe body 10 is formed with a handle through hole 12 that runs through the standpipe body 10 transversely and can be used to assemble a bicycle handle 40; And the front fork through hole 14 that can be used for assembling a front fork tube of a bicycle is formed at one end of the handle through hole 12 of the standpipe body 10 to form an insertion hole 16 communicating with the handle through hole 12. A cover 17 for closing the insertion hole 16 may be provided on the upper surface, and a window hole 18 communicating with the inside of the standpipe body 10 is provided on the top surface of the standpipe body 10 .

Thereby, when it is desired to assemble the electronically controlled instrument 20 with a display screen on the vertical pipe, the electronically controlled instrument 20 can be placed inside the vertical pipe body 10 from front to rear through the insertion hole 16 at one end of the vertical pipe body 10, And make the display screen on the electronic control instrument 20 relative to the window hole 18, then extend into the vertical pipe body 10 from the side of the standpipe body 10 with bolts and other fixing parts 30 and lock into the electric control instrument 20, so that the electric control The instrument 20 is fixed inside the standpipe body 10, and finally the insertion hole 16 is closed with the cover 17, and the assembly of the electric control instrument can be completed.

In addition, in accordance with the shape of the electronic control instrument 20 , a flange 182 protruding from the inner periphery of the window hole 18 can be abutted against the top surface of the electronic control instrument 20 , so as to improve the stability of the assembly of the electronic control instrument 20 .

Because the electronically controlled instrument 20 is inserted into the standpipe body 10 from front to back through the insertion hole 16 on the standpipe body 10, the size of the window hole 18 provided on the standpipe body 10 only needs to be the same as that of the electric control. The size and shape of the display screen on the instrument 20 can be matched, and it is not necessary to match the size and shape of the entire electronic control instrument 20, so the area of the window hole 18 can be effectively reduced, and the standpipe body can be effectively reserved. 10 to effectively enhance the structural strength of the standpipe body 10 itself.

In addition, lines such as electric wires or signal lines used in conjunction with the electronic control instrument 20 can also be matched with each other through the insertion hole 16 and the window hole 18, so as to facilitate the assembly or connection of the electric control instrument 20 and the electric system of the bicycle, which can improve the electronic control instrument. Overall efficiency of assembly.
