Referring to fig. 1, 2 and 3, fig. 1 is a perspective view of a bicycle seat post structure 10 according to embodiment 1 of the present invention, fig. 2 is a perspective view of a down tube 200 of embodiment 1 of fig. 1, and fig. 3 is a top view of the down tube 200 of embodiment 1 of fig. 2. The bicycle seat post structure 10 includes an upper tube 100 and a lower tube 200, the lower tube 200 having a first central axis I1 and including an inserting space S1 and a routing channel S2. The inserting space S1 is used for the upper tube 100 to be movably inserted and has a second central axis I2, the routing channel S2 is located at one side of the inserting space S1 and is used for accommodating at least one wire 300 (shown in fig. 4); wherein the first central axis I1 is non-collinear with the second central axis I2.

Therefore, since the inserting space S1 is eccentrically disposed on the lower tube 200, the lower tube 200 has enough space to form the routing channel S2, and the wire 300 can be prevented from protruding out of the outer wall of the lower tube 200. The details of the bicycle seat post structure 10 will be described later.

The lower tube 200 may have a circular tube structure, and the lower tube 200 may further include a partition wall 210, wherein the partition wall 210 is spaced by an insertion space S1 and a routing channel S2 along the direction of the first central axis I1. As shown in fig. 2 and fig. 3, the partition wall 210 has an arc shape in cross section, so as to separate the circular insertion space S1 and the arc-shaped routing channel S2, and the routing channel S2 may have a third central axis I3; the first central axis I1, the second central axis I2 and the third central axis I3 are coplanar and non-collinear. It should be particularly noted that, since fig. 3 is a top view, the first central axis I1, the second central axis I2 and the third central axis I3 are all illustrated by solid points, and the three solid points are located on a straight line, i.e. represent that the first central axis I1, the second central axis I2 and the third central axis I3 are coplanar. In the present invention, the centroid is calculated from the peripheral wall (ignoring part of the unevenness) surrounding the space or the outer wall (ignoring part of the unevenness) of the pipe body, and the axis passing through the centroid is defined as the central axis. In other embodiments, the cross-sectional shape of the insertion space may be changed according to the shape of the upper tube, and the cross-section of the routing channel may also be circular or other shapes, which is not limited to this.

The lower tube 200 may further include a protruding ring portion 220 protruding outward along the first central axis I1, and the protruding ring portion 220 may extend from the partition wall 210 to help the outer ring 700 to be sleeved.

Referring to fig. 4 and also to fig. 1 to 3, wherein fig. 4 is a cross-sectional side view of the bicycle seat post structure 10 of the embodiment of fig. 1 taken along the sectional line 4-4, and the operation control assembly 600 in fig. 4 is omitted from fig. 1 for simplicity of illustration, without limiting the present invention. The upper tube 100 also has a circular tube structure, the upper tube 100 can be inserted into the lower tube 200 from the upper end of the lower tube 200, and there can be a relative movement between the upper tube 100 and the lower tube 200, so as to change the height of the upper tube 100 exposed out of the lower tube 200.

As shown in fig. 4, the bicycle seat post structure 10 can further include a height adjustment mechanism 400, a driving group 500 and a manipulating group 600. The height adjusting mechanism 400 is disposed inside the upper pipe 100 and the lower pipe 200 and includes an actuating rod 410; the driving group 500 is controlled to push the actuating rod 410; the control assembly 600 controls the actuation of the driving assembly 500 and includes a signal receiving terminal 610 electrically connected to the driving assembly 500 through the at least one wire 300. The wire body 300 may be a wire capable of transmitting an electronic signal.

The height adjustment mechanism 400 may further include a tube 420, a valve (not shown) and a piston (not shown), wherein the actuating rod 410 extends into the tube 420, when the actuating rod 410 is pushed, the valve is opened, and the piston moves to move the upper tube 100 and the lower tube 200 relatively. The technology of this part is the prior art and is not the focus of the present invention, so it is not shown in the drawings and the details are not described again.

The driving assembly 500 may include a motor 510, a base 520, and a pushing seat 530, wherein the motor 510 drives the pushing seat 530 to rotate, and the pushing seat 530 and the base 520 include corresponding spiral guide surfaces, so that the pushing seat 530 may ascend relative to the base 520 after rotating to push the actuating rod 410, so that the actuating rod 410 opens the valve.

The steering group 600 may further include a signal transmitting end 620 for a user to operate to transmit a wireless signal to the signal receiving end 610, and the signal receiving end 610 drives the motor 510 through the line body 300.

Since the routing channel S2 is accommodated by the wire 300, even if the driving assembly 500 is disposed at the lower end of the lower tube 200 and the signal transmitting terminal 620 is disposed at the upper end of the lower tube 200, the wire 300 can still connect the two without protruding out of the outer wall of the lower tube 200.

Referring to fig. 5, fig. 5 is a cross-sectional side view of a bicycle seat post structure 20 in accordance with embodiment 2 of the present invention. A bicycle seat post structure 20 of embodiment 2 is similar to embodiment 1 with the difference that the drive group 500a and the operating group 600a are different. In more detail, the driving set 500a may include a lever 540a and a pulley 550 a; the operation set 600a is a wrench structure, and the operation set 600a is connected to the driving lever 540a of the driving set 500a through a wire and guided by the pulley 550a, so that when the operation set 600a is wrenched, the driving lever 540a of the driving set 500a can be controlled to push against an actuating rod (not shown), and the wire is a steel cable. In other words, for the height adjusting mechanism driven by electricity or manually, the wire body can be accommodated in the wire channel.

Referring to fig. 6, fig. 6 is a schematic top cross-sectional view of a lower tube 200b of a bicycle seat post structure in accordance with embodiment 3 of the present invention. The lower tube 200b can include a long opening 230b, the long opening 230b is disposed on the outer wall of the lower tube 200b along the direction of the first central axis (not shown), and the long opening 230b is communicated with the routing channel S2 to expose the routing channel S2. With this structure, even though the routing channel S2 is exposed by the long opening 230b, the wire can still be accommodated in the routing channel S2 and does not protrude out of the outer wall of the lower tube 200 b.

Referring to fig. 7, fig. 7 is a top cross-sectional view of a lower tube 200c of a bicycle seat post structure in accordance with a 4 th embodiment of the present invention. The routing channel S2 is in radial communication with the insertion space S1, and in this structure, the cross section of the insertion space S1 is still substantially circular and can be matched with an upper tube (not shown), and the routing channel S2 is a part other than a circle and can accommodate a wire body.

Although the present invention has been described with reference to the above embodiments, it will be understood by those skilled in the art that various changes and modifications may be made without departing from the spirit and scope of the invention, and therefore, the scope of the invention is to be defined by the appended claims.
