1. Field of the Invention
The present invention relates to a cooling device, and more particularly to a cooling device for a braking system.
2. Description of Related Art
Bicycles are very popular today. When a rider rides a bicycle along a downhill, a braking system ensures the safety for the rider. Recently, the braking system is driven by a hydraulic system which drives two clamping plates in the braking system to clamp a braking disc, so as to slow down a rotational speed of wheels of the bicycle. In addition, when the rider rides along the downhill, the rider needs to frequently brake the bicycle because of safety; as a result, the clamping plates would be overheated and a friction efficiency between each clamping plate and the braking disc would be further reduced. Therefore, how to cool the clamping plates is an important topic in this related art.
Some manufacturers set a plurality of openings opened around the braking disc so as to allow ambient air to flow through the openings, so that the ambient air flowing through the openings could absorb the heat emitted from the clamping plates; as a result, the clamping plates are cooled when the braking disc rotates. However, although the ambient air flowing through the openings absorbs the heat emitted from the clamping plates, said ambient air just indirectly blows the clamping plates rather than directly blow the clamping plates. Therefore, the clamping plates cannot be cooled efficiently.
The present invention has arisen to mitigate and/or obviate the disadvantages of the conventional braking system.
The main objective of the present invention is to provide an improved cooling device.
To achieve the objective, a cooling device for a braking system, which is assembled onto a hydraulic braking system of a bicycle, comprises a blower having a case and a fan, the case having an air outlet opened at one end thereof and an air inlet opened at another end thereof, the air outlet corresponding to the hydraulic braking system, the case having a receiving room defined therein, the receiving room communicating with the air outlet and the air inlet, the fan rotatably assembled in the receiving room, the blower further having a power supplier electrically connected to the fan, the power supplier being used to power the fan, one end of a frame connected to the hydraulic braking system, another end of the frame connected to the case of the blower. Wherein, the blower is further controlled by a wired controller or a wireless controller which is assembled onto a handlebar of a bicycle; the wired controller has a starter and a switch plate; one end of the starter faces the handlebar; another end of the starter faces a brake lever; one end of the switch plate is pivoted on another end of the starter; a spring is assembled between the starter and the switch plate; one end of the spring abuts against the starter; another end of the spring abuts against the switch plate; when a rider pulls the brake lever to operate the hydraulic braking system, the switch plate is smoothly pressed by the brake lever; as a result, the starter starts the power supplier to power the blower; the wired controller further has an electric wire; the electric wire is electrically connected between the starter and the power supplier of the blower; the wireless controller has a detector; the detector corresponds to one side of a brake lever; the detector is used to detect a motion of the brake lever; the detector is wirelessly connected to the power supplier of the blower; the frame has a positioning portion; the positioning portion is connected to the hydraulic braking system; the frame has a connecting portion; the connecting portion is connected to the blower; the frame has a middle portion; the middle portion is defined between the positioning portion and the connecting portion; the connecting portion has an assembling hole opened therethrough; the case of the blower has an assembling opening opened therethrough; the assembling opening of the case corresponds to the assembling hole of the connecting portion; a screw unit passes through the assembling hole and is further screwed into the assembling opening, so that the blower is assembled on the frame; the positioning portion of the frame has a positioning hole opened therethrough; a screw member passes through the positioning hole and a further positioning hole of the hydraulic braking system, and is further screwed into a tube near a brake disk of a bicycle, so that the frame is positioned on the tube near the brake disk of the bicycle; the positioning portion is perpendicularly connected to one end of the middle portion; another end of the middle portion is perpendicularly connected to the connecting portion, so that the frame is generally U-shaped; the connecting portion is inclinedly extended relative to the blower.
Therefore, the blower directly blows the hydraulic braking system so as to efficiently cool the hydraulic braking system.
Further benefits and advantages of the present invention will become apparent after a careful reading of the detailed description with appropriate reference to the accompanying drawings.
Referring to
The blower 2 is further controlled by a wired controller 5 or a wireless controller 6.
In regards to the wired controller 5, the wired controller 5 is assembled onto a handlebar (as shown in
In addition, a spring 53 is assembled between the starter 51 and the switch plate 52. When the rider pulls the brake lever to operate the hydraulic braking system 1, the spring 53 is compressed by the switch plate 52; one end of the spring 53 abuts against the starter 51; another end of the spring 53 abuts against the switch plate 52. In contrast, when the rider releases the brake lever, the switch plate 52 is moved to an initial position thereof by a recovery force of the spring 53; as a result, the starter 51 stops starting the blower 2 via said motion of the switch plate 52. Therefore, the blower 2 stops operating when the hydraulic braking system 1 is not operated.
In regards to the wireless controller 6, the wireless controller 6 is assembled onto a handlebar (as shown in
Furthermore, the frame 3 has a positioning portion 31. The positioning portion 31 is connected to the hydraulic braking system 1 so as to position the frame 3 onto the hydraulic braking system 1. The frame 3 has a connecting portion 32. The connecting portion 32 is connected to the blower 2 so as to connect the blower 2 to the frame 3. The frame 3 has a middle portion 33. The middle portion 33 is defined between the positioning portion 31 and the connecting portion 32. The positioning portion 31, the connecting portion 32 and the middle portion 33 are all plate-shaped. The connecting portion 32 has an assembling hole 321 opened therethrough. The case 21 of the blower 2 has an assembling opening 214 opened therethrough. The assembling opening 214 of the case 21 corresponds to the assembling hole 321 of the connecting portion 32. A screw unit 7 passes through the assembling hole 321 and is further screwed into the assembling opening 214, so that the blower 2 is assembled on the frame 3. The positioning portion 31 of the frame 3 has a positioning hole 311 opened therethrough. A screw member 8 passes through the positioning hole 311 and a further positioning hole of the hydraulic braking system 1 (as shown in
