Description

Shock-absorbing seat post with warning light

This creation is related to bicycles, and in particular to a suspension seatpost with a warning light.

The bicycle seat tube is a connection mechanism used to connect the frame and the seat. It can be adjusted to the height of the protrusion from the frame according to the height of the rider to improve the smoothness and comfort of the ride. The traditional bicycle seat tube is locked and released through pins and bolt-type clamps. Such clamps are time-consuming and require tools during the adjustment process, so the quick seat tube clamp was developed later to allow the rider to quickly release it to adjust the height. The seat tube has further evolved into a shock-absorbing seat tube with a shock-absorbing mechanism, which can effectively absorb impact when the road surface is uneven, so that the rider has a more comfortable ride.

However, the above-mentioned shock-absorbing seat posts only focus on riding comfort and only improve the shock-absorbing mechanism, such as the connecting rod connection, the configuration of the elastic parts, etc. It is obvious that the developers have ignored the consideration of safety. Therefore, it is necessary to provide a novel and progressive shock-absorbing seat post with a warning light source to solve the above-mentioned problems.

The main purpose of this invention is to provide a shock-absorbing seat post with a warning light source, which can provide the rider with a more comfortable riding experience through the shock-absorbing mechanism, and use the light body as a warning light source to inform and remind surrounding road users, thereby protecting the rider's road safety, so that the shock-absorbing seat post with a warning light source has both riding comfort and riding safety.

To achieve the above purpose, the invention provides a shock-absorbing seat post with a warning light source, comprising: a seat tube, a shock-absorbing mechanism, a lamp body and a wire. The shock-absorbing mechanism is arranged on the seat tube for mounting a seat cushion; the lamp body is arranged on the shock-absorbing mechanism; the wire is connected to the lamp body and a power source respectively through the shock-absorbing mechanism.

The following is merely an example to illustrate possible implementations of the present invention, but it is not intended to limit the scope of protection for the present invention. The "one" or "at least one" preceding the terms mentioned in the text does not limit the quantity, and it can also be "plural" according to needs. This change in quantity is also within the scope of protection, which should be stated in advance.

Please refer to Figures 1 to 6, which show an embodiment of the present invention. The shock-absorbing seatpost with a warning light source of the present invention includes: a seat tube 1, a shock-absorbing mechanism 2, a lamp body 4 and a wire 5.

The shock absorber 2 is provided on the seat tube 1 for mounting a seat cushion. When the bicycle encounters bumps on the road, the shock absorber 2 can effectively absorb the impact force to give the rider a more comfortable riding experience. The light body 4 is provided on the shock absorber 2 to form a synchronous relationship. The light body 4 is used as a warning light source to inform and remind surrounding road users to protect the road safety of the rider. The wire 5 is connected to the light body 4 and a power source 7 through the shock absorber 2. The wire 5 can be, for example but not limited to, passing by the shock absorber 2 or passing through the shock absorber 2. The manufacturer can change it according to different styles.
