Description

Technical Field

[0001] This utility model relates to the field of bicycle accessories technology, specifically to a seat post bracket and a bicycle. Background Technology

[0002] As a common means of transportation and sports equipment, bicycles typically require various accessories, such as speedometers, headlights, and taillights, to enhance the riding experience and safety. These accessories are usually fixed to the bicycle's seatpost using brackets.

[0003] In existing technologies, seat post supports are mostly fixed by direct clamping or bolting, such as using metal clamps or plastic clips to directly tighten the seat post. However, these methods have some drawbacks: First, the installation process is cumbersome, requiring tools to adjust the bolts, and it is difficult to adapt to seat posts of different diameters; second, rigid fixing methods are prone to leaving indentations or scratches on the surface of the seat post, affecting its appearance and service life. Utility Model Content

[0004] Based on the above description, this utility model provides a seatpost bracket and a bicycle, aiming to solve the problems of inconvenient installation, poor adaptability, and easy damage to the seatpost of existing seatpost brackets.

[0005] The technical solution of this utility model to solve the above-mentioned technical problems is as follows: In a first aspect, this utility model provides a seat tube support, comprising: Public seat; A fixed bracket includes a main body and two connecting arms. The main body is connected to the male seat. The two connecting arms are symmetrically arranged about a defined axis. One end of each connecting arm is connected to the main body. Each connecting arm is provided with a hook. An elastic ring surrounds the seat post of the bicycle and hooks the two hooks onto the elastic ring.

[0006] Based on the above technical solution, the present invention can be further improved as follows.

[0007] Furthermore, the surface of the main body that contacts the seat post of the bicycle is an inclined surface.

[0008] Furthermore, the inclination angle of the inclined plane is 5°~10°.

[0009] Furthermore, each of the connecting arms is bent along one end near the main body to form a bent portion.

[0010] Furthermore, the bent portion is constructed in a Z-shape.

[0011] Furthermore, the male seat is provided with a plurality of connection holes, and the main body is provided with a through hole corresponding to each of the connection holes. The fixing bracket includes fasteners, and the fasteners correspond one-to-one with the through holes. The tail of the fastener passes through the through hole and is connected to the connection hole.

[0012] Furthermore, the connecting hole is a mounting hole, a nut is provided in the mounting hole, the fastener is a bolt, and the tail of the bolt passes through the through hole and is connected to the nut.

[0013] Furthermore, the fixing bracket is made of plastic.

[0014] Furthermore, the elastic ring is made of rubber.

[0015] Secondly, this utility model provides a bicycle, including the seat post bracket according to the first aspect.

[0016] Compared with the prior art, the technical solution of this application has the following beneficial technical effects: (1) This utility model achieves quick installation and disassembly through the hook and elastic ring of the connecting arm, which can be operated by the user without tools; the elastic deformation of the elastic ring can not only adapt to seat tubes of different diameters, but also reduce rigid contact, avoid scratches or indentations on the surface of the seat tube, make the overall structure stable, and keep the accessories firm during riding bumps.

[0017] (2) The present invention uses the inclined surface of the main body to adjust the seat connected to the main body to a state that is basically perpendicular to the ground, which compensates for the tilt angle of the seat tube and allows the accessories such as the bicycle lights installed on the seat to remain perpendicular to the ground. This ensures that the bicycle lights can effectively warn vehicles behind and enhance riding safety.

[0018] (3) The present invention not only enhances the elasticity and fatigue resistance of the connecting arm through the Z-shaped shape, ensuring that the hook can still maintain the hooked state under dynamic load, but also improves the adaptability of the bracket and is suitable for elastic rings of different sizes.

[0022] To facilitate understanding of this application, a more complete description will be provided below with reference to the accompanying drawings, which illustrate embodiments of the present application. However, the present application can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided so that the disclosure of this application will be thorough and complete.

The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the application.

[0024] It is understood that spatial relation terms such as "below," "under," "below," "below," "above," "above," etc., can be used here to describe the relationship between one element or feature shown in the figure and other elements or features. It should be understood that, in addition to the orientation shown in the figure, spatial relation terms also include different orientations of the device in use and operation.

Therefore, the exemplary terms "below" and "below" can include both upper and lower orientations. Furthermore, the device may also include other orientations (e.g., rotated 90 degrees or other orientations), and the spatial descriptive terms used herein will be interpreted accordingly.

[0025] When used herein, the singular forms of “a,” “an,” and “the” may also include the plural forms unless the context clearly indicates otherwise. It should also be understood that the terms “comprising,” “including,” or “having,” etc., specify the presence of the stated feature, whole, step, operation, component, part, or combination thereof, but do not preclude the possibility of the presence or addition of one or more other features, wholes, steps, operations, components, parts, or combinations thereof.

[0026] Reference Figures 1 to 6 As shown, this utility model provides a technical solution: a seat post bracket, including a male seat 10, a fixed bracket 20, and an elastic ring 30; the fixed bracket 20 includes a main body 21 and two connecting arms 22, the main body 21 is connected to the male seat 10, the two connecting arms 22 are symmetrically arranged about a defined axis, one end of each connecting arm 22 is connected to the main body 21, and each connecting arm 22 is provided with a hook 221; the elastic ring 30 surrounds the seat post of the bicycle and the two hooks 221 are hooked onto the elastic ring 30.

[0027] In this embodiment, the male seat 10 is used to secure accessories, such as a speedometer or bicycle lights. An elastic ring 30 forms a closed loop around the seat post, and a hook 221 engages with the elastic ring 30, using the tension of the elastic ring 30 to firmly hold the mounting bracket 20 against the seat post. The symmetrically arranged connecting arms 22 ensure even force distribution and prevent the bracket from tilting. This connection method allows for quick installation and removal, requiring no tools from the user. The elastic deformation of the elastic ring 30 not only accommodates seat posts of different diameters but also reduces rigid contact, preventing scratches or indentations on the seat post surface, thus stabilizing the overall structure and keeping accessories securely in place during bumpy riding.

[0028] Reference Figures 4 to 5 As shown, in some embodiments, the surface of the main body 21 that contacts the seat post of the bicycle is an inclined surface.

[0029] In this embodiment, the ramp is specifically designed to contact and conform to the inclined seatpost surface of the bicycle. Since most bicycle seatposts are not perpendicular to the ground but have a certain tilt angle, matching the ramp's angle to the seatpost's inclination ensures that when the mounting bracket 20 is fixed to the seatpost by the elastic ring 30, the main body 21 can conform to the seatpost with maximum area. This conformation ultimately allows the male seat 10, connected to the main body 21, to be adjusted to a state that is essentially perpendicular to the ground. The ramp compensates for the seatpost's tilt angle, ensuring that accessories such as lights mounted on the male seat 10 remain perpendicular to the ground. This ensures the lights effectively warn vehicles behind, enhancing riding safety.

[0030] Optionally, the inclination angle of the inclined plane is 5° to 10°.

[0031] In this embodiment, this angle range can effectively and accurately compensate for the tilt of the seat tube. If the tilt angle is too small, the compensation will be insufficient, and the male seat 10 will still tilt backward; if the tilt angle is too large, it will lead to overcompensation, and the male seat 10 will tilt forward. This tilt angle range ensures the accuracy of the accessory installation direction.

[0032] Reference Figures 1 to 2 and Figures 4 to 5 As shown, in some embodiments, each connecting arm 22 is bent along one end near the main body 21 to form a bent portion 222.

[0033] For example, the bent portion 222 is connected to the main body portion 21 at one end away from the hook 221.

[0034] In this embodiment, the bending portion 222 introduces an elastic deformation point on the connecting arm 22. When the hook 221 catches the elastic ring 30, the bending portion 222 can bend slightly. The bending portion 222 increases the flexibility of the connecting arm 22, making the bracket more adaptable to the tension changes of the elastic ring 30 and preventing the hook 221 from accidentally disengaging. At the same time, the bending portion 222 acts as a buffer, reducing the wear of the fixed bracket 20 and the seat tube.

[0035] Reference Figures 1 to 2 and Figures 4 to 5 As shown, in some embodiments, the bend 222 is configured in a Z-shape.

[0036] In this embodiment, the Z-shaped bend 222 provides greater elastic travel through multiple bending points, enabling it to better adapt to external forces. This shape not only enhances the elasticity and fatigue resistance of the connecting arm 22, ensuring that the hook 221 remains hooked under dynamic loads, but also improves the adaptability of the bracket, making it suitable for elastic rings 30 of different sizes.

[0037] Reference Figures 1 to 5 As shown, in some embodiments, the male seat 10 is provided with a plurality of connection holes 11, and the main body 21 is provided with a through hole 211 corresponding to each connection hole 11. The fixed bracket 20 includes a fastener 23, which corresponds one-to-one with the through hole 211. The tail of the fastener 23 passes through the through hole 211 and is connected to the connection hole 11.

[0038] In this embodiment, the main body 21 is connected to the male seat 10 by fastener 23, achieving a detachable fixing method. The corresponding design of the connecting hole 11 and the through hole 211 ensures alignment accuracy. This connection method makes the fixing bracket 20 flexible to install, easy to maintain and replace accessories; the fastener 23 provides a firm connection, preventing relative movement between the male seat 10 and the bracket, and improving overall stability.

[0039] Reference Figures 1 to 5As shown, in some embodiments, the connecting hole 11 is a mounting hole, a nut 12 is provided in the mounting hole, and the fastener 23 is a bolt, the tail of the bolt passes through the through hole 211 and is connected to the nut 12.

[0040] In this embodiment, a threaded connection of bolt and nut 12 is used. Tightening is achieved by rotating the bolt, and the self-locking property of the thread prevents loosening. The threaded connection ensures high strength and reliability, making it suitable for high-vibration environments.

[0041] Optionally, the mounting bracket 20 is made of plastic.

[0042] For example, the plastic material can be ABS plastic or nylon, etc.

[0043] In this embodiment, the plastic material is lightweight, easy to mold, and corrosion-resistant, allowing for mass production of the fixing bracket 20 through injection molding. The plastic bracket reduces the overall weight and lowers costs; simultaneously, the plastic's elasticity helps absorb impact and improves comfort.

[0044] For example, the elastic ring 30 is made of rubber.

[0045] In this embodiment, the rubber material has high elasticity and wear resistance, and can stretch and recover under external force, providing continuous clamping force. This ensures close contact with the seat post without damaging the seat post surface.

[0046] This utility model provides a technical solution: a bicycle, including the above-mentioned seat post bracket.

[0047] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
