[0031] To facilitate understanding of this application, a more detailed description is provided below with reference to the accompanying drawings and specific examples. It should be noted that when an element is described as "fixed to" another element, it can be directly on the other element, or one or more intermediate elements may exist between them. When an element is described as "connected to" another element, it can be directly connected to the other element, or one or more intermediate elements may exist between them. The terms "vertical," "horizontal," "left," "right," "inner," "outer," and similar expressions used in this specification are for illustrative purposes only.

[0032] Unless otherwise defined, all technical and scientific terms used in this specification have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used in this specification is for the purpose of describing particular embodiments only and is not intended to limit the scope of the application. The term "and / or" as used in this specification includes any and all combinations of one or more of the associated listed items.

[0033] Please see Figure 1 The seat post 100 provided in this embodiment includes: a tube body 10, a clamp 20, and a connector 30; one end of the connector 30 is disposed on the tube body 10; the other end of the connector 30 forms a mounting position 31, the mounting position 31 extends along a first direction D1, and the angle α between the first direction D1 and the axial direction o1 of the tube body 10 is greater than zero; the clamp 20 is used for clamping the seat cushion, the clamp 20 is detachably connected to the mounting position 31, and the position of the clamp 20 relative to the mounting position 31 along the first direction D1 can be adjusted. With this setting, the position of the chuck 20 relative to the mounting position 31 can be adjusted along the first direction D1. The first direction D1 does not coincide with the axial direction o1 of the tube body 10 (the included angle α between the two is greater than zero). This is equivalent to adjusting the position of the chuck 20 relative to the tube body 10. Therefore, the position of the saddle mounted on the chuck 20 relative to the tube body 10 can be adjusted, and the position of the saddle relative to the handlebars can be changed. Riders can adjust the position of the saddle according to their own riding habits and comfort to improve the riding experience.

[0034] In some embodiments, the angle α between the first direction D1 and the axial direction o1 of the tube 10 is preset. The angle α is set to facilitate riding, for example, the angle α between the first direction D1 and the axial direction o1 of the tube 10 is between 20 degrees and 80 degrees.

[0035] Regarding the aforementioned first direction D1, when the seat post 100 is mounted on a vehicle such as a bicycle or electric vehicle, the first direction D1 can be the forward direction, or the first direction D1 can be approximately the same as the forward direction.

[0036] In some embodiments, the mounting position 31 is provided with a waist-shaped hole 31a, the first direction D1 is the length direction of the waist-shaped hole 31a, the chuck 20 is detachably connected to the waist-shaped hole 31a, and the position of the chuck 20 relative to the waist-shaped hole 31a can be adjusted along the first direction D1. The provision of the waist-shaped hole 31a provides a specific way to adjust the position of the chuck 20 relative to the mounting position 31.

[0037] The length direction of the waist-shaped hole 31a is the direction of the two parallel straight line segments of the waist-shaped hole 31a.

[0038] It is understood that the adjustment of the position of the chuck 20 relative to the mounting position 31 is not limited to the form of the waist-shaped hole 31a described above. Other methods are also possible. For example, the mounting position 31 may be provided with multiple mounting holes (not shown in the figure), and the multiple mounting holes may be arranged at intervals along the first direction D1. By installing the chuck 20 in different mounting holes, the position of the chuck 20 relative to the mounting position 31 can be adjusted.

[0039] In some embodiments, please refer to Figure 2 The clamp 20 includes a locking assembly 21, a first fastener 22, and a locking element 23. The locking assembly 21 includes a first locking member 211 and a second locking member 212 disposed opposite to each other. The first fastener 22 passes through the first locking member 211, the mounting position 31, and the second locking member 212 to lock the locking assembly 21 to the mounting position 31. When the mounting position 31 is provided with the waist-shaped hole 31a, the first fastener 22 passes through the first locking member 211, the waist-shaped hole 31a, and the second locking member 212 to lock the locking assembly 21. The locking element 23 is detachably connected to the locking assembly 21. The locking element 23 and the locking assembly 21 are used to clamp the seat cushion. With this setting, the position of the locking assembly 21 relative to the mounting position 31 can be easily adjusted, that is, the position of the entire clamp 20 relative to the mounting position 31 can be easily adjusted to ensure a tight fit between the clamp 20 and the mounting position 31.

[0040] It is worth noting that the first fastener 22 may be a locking part such as a screw, bolt or stud.

[0041] In some embodiments, the clamp 20 further includes two second fasteners 24, and the locking fastener 23 covers the end of the first locking member 211 opposite to the tube body 10 and the end of the second locking member 212 opposite to the tube body 10. One of the second fasteners 24 locks the first locking member 211 and the locking fastener 23, and the other second fastener 24 locks the second locking member 212 and the locking fastener 23. With this arrangement, the position of the seat cushion can be easily adjusted and fixed by the clamp 20, ensuring a tight fit between the seat cushion and the clamp 20.

[0042] It is worth noting that the second fastener 24 can be a locking part such as a screw, bolt or stud.

[0043] In some embodiments, the first locking member 211 is provided with a first groove 211a, the second locking member 212 is provided with a second groove 212a, and the locking member 23 is provided with two third grooves 23a at intervals. The first groove 211a and one of the third grooves 23a surround to form a first mounting groove 2a, and the second groove 212a and the other of the third grooves 23a surround to form a second mounting groove 2b. The first mounting groove 2a and the second mounting groove 2b are used for the installation of the seat cushion. With this arrangement, the seat cushion can be fixed to the first mounting groove 2a and the second mounting groove 2b, improving the connection reliability between the seat cushion and the clamp 20.

[0044] It is worth noting that in some embodiments, the first groove 211a extends along the first direction D1, the second groove 212a extends along the first direction D1, the first mounting groove 2a extends along the first direction D1, and the second mounting groove 2b extends along the second direction D2.

[0045] In some embodiments, the first groove 211a is a through groove and the second groove 212a is a through groove to accommodate the installation of the connecting rod on the seat cushion.

[0046] Understandably, the connecting rod on the seat cushion is generally a round tube. Therefore, the cross-section of the first groove 211a is arc-shaped, the cross-section of the second groove 212a is arc-shaped, and the cross-section of the third groove 23a is arc-shaped. Thus, the cross-section of the first mounting groove 2a formed by the first groove 211a and the third groove 23a is arc-shaped, and the cross-section of the second mounting groove 2b formed by the second groove 212a and the third groove 23a is arc-shaped, which facilitates the fitting of the round tube-shaped connecting rod on the seat cushion.

[0047] In some embodiments, the number of the first fasteners 22 is two, and the two first fasteners 22 are spaced apart along the first direction D1. This arrangement improves the reliability of the first fasteners 22 in locking the first locking member 211 and the second locking member 212 to the mounting position 31.

[0048] In some embodiments, please refer to Figure 3 The first fastener 22 includes a first fastening element 221 and a second fastening element 222. The first fastening element 221 is provided with a locking groove 221a. The first fastening element 221 extends to the second fastening element 212 after passing through the first locking member 211 and the mounting position 31. The second fastening element 222 passes through the second locking member 212 and is locked in the locking groove 221a. This arrangement improves the reliability of the first fastener 22 in locking the first locking member 211 and the second locking member 212 to the mounting position 31.

[0049] It is worth noting that the first fastening element 221 can be a locking part such as a screw, bolt, or stud. The second fastening element 222 can be a locking part such as a screw, bolt, or stud.

[0050] In some embodiments, a second direction D2 is defined to be perpendicular to both the axial direction o1 of the tube body 10 and the first direction D1. Along the second direction D2, the width w of the mounting position 31 is smaller than the diameter d of the tube body 10. The mounting position 31 is flat to facilitate locking of the clamp 20. When the clamp 20 includes the first locking member 211 and the second locking member 212, the first locking member 211 and the second locking member 212 are located on both sides of the flat mounting position 31 to facilitate locking the first locking member 211 and the second locking member 212 to the mounting position 31.

[0051] In some embodiments, please refer to Figure 4 One end of the connector 30 is inserted into the pipe body 10 along the axial direction o1, providing a specific manner in which one end of the connector 30 is disposed in the pipe body 10. It is understood that the manner in which one end of the connector 30 is disposed in the pipe body 10 is not limited to the above form.
