Description

[Technical Field]

[0001] This invention relates to bicycles, and more particularly to a shock-absorbing seat post with a warning light source. [Previous Technology]

[0002] The bicycle seatpost is the connecting mechanism between the frame and the saddle. Its height protruding from the frame can be adjusted to suit the rider's height, improving riding smoothness and comfort. Traditional bicycle seatpost positioning uses pins and bolt-type clamps for locking and releasing. These clamps are time-consuming and require tools during adjustment, so quick-release seatpost clamps were later developed to allow riders to quickly release and adjust the height. The seatpost has further evolved into a shock-absorbing seatpost with a shock-absorbing mechanism, which effectively absorbs impact when the road surface is uneven, providing a more comfortable ride.

[0003] However, the aforementioned shock-absorbing seatposts all focus solely on riding comfort and only improve the shock-absorbing mechanism, such as linkage connections and the configuration of elastic components, etc., clearly neglecting safety considerations. Therefore, it is necessary to provide a novel and advanced shock-absorbing seatpost with a warning light source to solve the above problems. [Summary of the Invention]

[0004] The main objective of this invention is to provide a shock-absorbing seat post with a warning light source. The shock-absorbing mechanism provides riders with a more comfortable riding experience, while the light source serves as a warning light source to inform and remind surrounding road users, thus protecting the rider's road safety. Therefore, the shock-absorbing seat post with a warning light source has both the functions of riding comfort and riding safety.

[0005] To achieve the above objectives, the present invention provides a shock-absorbing base pole with a warning light source, comprising: a base tube, a shock-absorbing mechanism, a lamp body, a wiring channel, and a wire. The shock-absorbing mechanism is disposed on the base tube for mounting a seat cushion; the lamp body is disposed on the shock-absorbing mechanism; the wiring channel extends through the shock-absorbing mechanism and into the interior of the base tube; one end of the wire is connected to the lamp body, and the other end passes through the wiring channel, through the shock-absorbing mechanism, and into the interior of the base tube for connection to a power source.

Implementation Method

[0006] The following are only examples illustrating possible implementations of the present invention, but are not intended to limit the scope of protection of the present invention. The "a" or "at least one" prefixed to the terms mentioned herein are not intended to limit the quantity, and may also be "multiple" depending on the needs. Such variations in quantity are also within the scope of protection, and are therefore stated in advance.

[0007] Please refer to Figures 1 to 6, which show one embodiment of the present invention. The shock-absorbing base rod with warning light source of the present invention includes: a base tube 1, a shock-absorbing mechanism 2, a lamp body 4 and a wire 5.

[0008] The shock absorption mechanism 2 is located on the seat post 1 to support the saddle. When the bicycle encounters bumpy roads, the shock absorption mechanism 2 can effectively absorb the impact force, giving the rider a more comfortable riding experience. The light body 4 is located on the shock absorption mechanism 2 and moves in tandem with it. The light body 4 serves as a warning light source to inform and remind surrounding road users, thereby protecting the rider's road safety. One end of the wire 5 is connected to the light body 4, and the other end passes through the wiring channel 6, through the shock absorption mechanism 2, and into the interior of the seat post 1 to connect to a power source 7. Examples of the wire 5, but not limited to, passing by the shock absorption mechanism 2 or passing through the shock absorption mechanism 2, can be varied by the manufacturer depending on the style and design. The power source 7 can be a battery specifically for the light body 4 or an electrical system connected to the bicycle frame.

[0009] More specifically, the shock-absorbing base rod with warning light source also includes a wire channel 6, which extends through the shock-absorbing mechanism 2 and into the interior of the base tube 1. The wire 5 can be smoothly connected to the power source 7 and the lamp body 4 through the wire channel 6. Preferably, the minimum radial dimension of the wire channel 6 is at least 1.5 times the radial dimension of the wire 5, so as to leave enough space for the wire 5 to move and deform.

[0010] More specifically, the shock absorption mechanism 2 includes a linkage component 3 and an elastic member 37. The linkage component 3 is movably disposed on the seat tube 1 for assembling a seat cushion. The lamp body 4 is connected to the linkage component 3. The elastic member 37 springs against the linkage component 3 to provide elastic force to the linkage component 3, so that the linkage component 3 has the ability to return to its initial position.

[0011] For example, but not limited to, the elastic element 37 is selected from either a spring or urethane rubber. The base tube 1 has a threaded section 11 on its inner wall on the side away from the lamp body 4. A support seat 12 is screwed to the threaded section 11. The elastic element 37 is housed inside the base tube 1 and springs against the support seat 12 and the shock-absorbing mechanism 2. By rotating the support seat 12, the preload of the elastic element 37 can be changed, thus providing different elastic forces to the linkage component 3. In this embodiment, the elastic element 37 is a spring. The wire 5 passes through the center of the elastic element 37. The support seat 12 has a through hole 13 through which the wire 5 can pass for connection to the power source 7.

[0012] Please further refer to another embodiment of Figure 7, the difference being that the assembly position of the elastic member 37 is different. The linkage component 3A and the seat tube 1A together form an internal space 39. The elastic member 37A is housed in the internal space 39. The elastic member 37A is made of urethane material. In a preferred embodiment, it is solid. The side of the elastic member 37A extends to a portion of the bottom surface and has a recessed groove 371. The wire 5A passes through the linkage component 3A and extends along the groove 371 into the interior of the seat tube 1A. Preferably, the inner diameter of the groove is slightly smaller than the diameter of the wire, so that the wire can be tightly fitted and fixed into the groove to prevent the elastic member 37 from deforming and squeezing the wire. At the same time, this assembly method can also achieve the ability of the linkage component 3A to return to its initial position.

[0013] Referring further to Figures 1 to 6 of this embodiment, the linkage assembly 3 includes a base 31, a pushing unit 32, at least one linkage rod, and a head seat 38. The base 31 is positioned on the seat tube 1, and the elastic member 37 is telescopically accommodated in the seat tube 1. The at least one linkage rod is pivotally connected to the head seat 38 and the base 31 respectively, so that the head seat 38 can move relative to the base 31. The lamp body 4 is disposed on the head seat 38, and the pushing unit 32 is connected between the at least one linkage rod and the elastic member 37. In this embodiment, the lamp body 4 is disposed at the protruding extension of the head seat 38 toward the seat tube 1, and the direction in which the head seat 38 protrudes toward the seat tube 1 is oblique to the seat tube 1.

[0014] Furthermore, the push unit 32 includes a piston 321 and a push rod 326. The piston 321 is movably accommodated in the seat tube 1. One side of the piston 321 is used to press against the elastic member 37. The two sides of the push rod 326 are respectively pivotally connected to the piston 321 and the at least one linkage rod, thereby enabling rotational movement and linear movement. The piston 321 has a through hole 322, which connects the outside to the inside of the seat tube 1. The wire 5 passes through the through hole 322 to enter the center of the elastic member 37. In the direction perpendicular to the seat tube 1, the push rod 326 is kept in an overlapping configuration with the lamp body 4.

[0015] In this embodiment, the number of at least one linkage is two, and they are respectively defined as a first linkage 33 and a second linkage 35. The first linkage 33 is recessed with a groove 34. One end of the push rod 326 extends into the groove 34 and is pivotally connected to the first linkage 33. The groove 34 provides a safe and unobstructed environment for the push rod 326 to perform pivoting action. The second linkage 35 is provided with a plurality of buffer bodies 36 on one side facing the first linkage 33. When the second linkage 35 swings toward the first linkage 33, the plurality of buffer bodies 36 can absorb the impact force to protect the structural integrity of both the first linkage 33 and the second linkage 35.

[0016] Preferably, the push unit 32 further includes at least one pad 327, which is disposed on the outer peripheral wall of the piston 321 and can slide against the inner wall of the seat tube 1, thereby allowing wear to be concentrated on the at least one pad 327 to protect the structural integrity of the piston 321.

[0017] Specifically, the piston 321 includes a main body 323 and two lugs 325. The through hole 322 passes through the main body 323. The two lugs 325 protrude from the main body 323. The push rod 326 is pivotally connected to the two lugs 325. The through hole 322 passes through the main body 323 and the opening facing the push rod 326 is flared. At least one pad 327 is disposed on the main body 323. The at least one pad 327 is a metal ring and has better structural strength, wear resistance and smoothness. In this embodiment, the at least one pad 327 includes a plurality of pads 327, and the main body 323 has an annular groove 324 recessed between two adjacent pads 327. Part of the at least one pad 327 does not abut against the inner wall of the seat tube 1 to form a gap that can communicate with the annular groove 324. In this way, air during the sliding process of the piston 321 can flow smoothly between the inside of the seat tube 1 and the outside.

[0018] It should be further explained that the area through which the wire 5 can pass is part of the wire passage 6. In this embodiment, the through hole 13, the through hole 322 and the center of the elastic member 37, and the inside of the seat tube 1 all belong to the wire passage 6.
