The combination structure of bicycle frame and seat post

Abstract

This invention relates to an installation structure for a bicycle frame and a bottom tube, which solves the problem of conventional bicycles requiring a lot of time to assemble. It includes: a frame having a bottom tube and a straight tube, wherein the bottom tube and the straight tube are connected to form a receiving space; a support assembly installed within the receiving space of the frame; and a motor installed within the receiving space of the frame and connected to the straight tube, with a first spindle of the motor connected to a lever on the support assembly. The support assembly, pre-installed within the receiving space of the frame and housing the motor, controls the up-and-down movement of the bottom tube via electronic signal transmission.

Claims

1. A bicycle frame and seatpost assembly, comprising: a frame having a center tube and a straight tube, wherein the center tube and the straight tube are connected to each other to form an accommodating space; a seat assembly being disposed within the accommodating space of the frame; and a motor being disposed within the accommodating space of the frame and connected to the straight tube, wherein a first spindle of the motor is connected to a lever of the seat assembly.

2. The bicycle frame and seat post combination structure as described in claim 1, wherein the support assembly includes a center tube base and a locking member, and the locking member is connected below the center tube base, wherein the center tube base has a through hole, a space and a first straight hole, and the through hole and the first straight hole respectively penetrate the space.

3. The bicycle frame and seat post combination structure as described in claim 2, wherein the lever of the bearing assembly is provided with a mounting hole connected to a center of the locking member.

4. The bicycle frame and seat post combination structure as described in claim 2, wherein the bearing assembly includes a compression block, and a portion of the compression block is placed in the space of the center tube base, and the compression block has a compression hole communicating with the through hole, and the compression block has a second straight hole opposite to the first straight hole, such that the first straight hole communicates with the second straight hole.

5. The bicycle frame and seatpost combination structure as described in claim 4, wherein the frame further includes a seatpost, a telescopic cylinder and a control component, and a second spindle of the telescopic cylinder is connected to the control component, and the second spindle extends through the second straight hole and the first straight hole respectively, so that the control component is disposed in the first straight hole and contacts the lever, and wherein a positioning hole is provided on the surface of the center tube.

6. The bicycle frame and seatpost assembly as described in claim 5, wherein the seat assembly includes a positioning member that extends through a positioning hole in the center tube and a through hole in the center tube base and abuts against the pressure of the pressure block, thereby fixing the seat assembly inside the receiving space.

7. The bicycle frame and seat post assembly structure as described in claim 2, wherein the locking element and the center tube support are connected by screws.
