Description

[Technical Field]

[0001] This invention relates to a brake, and in particular to a brake grip structure provided in the grip to reduce the width of the grip handle, making it convenient for long-term gripping and braking. [Previous Technology]

[0002] Note that in commonly used riding tools with handlebars, such as bicycles, motorcycles, and balance bikes, users hold their hands on the handlebars to control the direction of travel. In order to reduce speed or stop during travel, a brake lever is attached to the outside of the handlebars. When braking, the brake lever can be pressed. During travel, the fingers should also be supported on the brake lever in preparation to avoid the need to brake in case of accidental situations.

[0003] However, when using a typical brake lever, the thumb needs to rest on the grip, and the other four fingers need to be placed across it. During prolonged riding, the area between the thumb and forefinger (the web between the thumb and index finger) can easily become sore and uncomfortable. Additionally, some users grip the grip directly with their fingers and then quickly move their fingers towards the brake lever to press it when braking is needed. However, this can easily result in slow braking or inaccurate braking due to the suddenness of the action, potentially causing an accident. Furthermore, in low-temperature environments, hands can easily become numb due to the cold, making it difficult to press the brake lever smoothly and affecting braking performance. [Summary of the Invention]

[0004] One objective of the present invention is to provide a brake grip structure that can reduce the span of the user's hand when gripping the grip by means of a pressing member provided in the opening of the grip.

[0005] One objective of this invention is to provide a brake grip structure, wherein the pressing element has a short actuation distance, which can quickly and effectively form a braking effect.

[0006] One objective of this invention is to provide a brake grip structure that can be installed on vehicles such as motorcycles and bicycles that use grips for directional operation, and has wide applicability.

[0007] To achieve the above objectives, the present invention provides a brake grip structure, comprising: a grip having a hollow chamber, an opening being provided around the outer periphery of the grip, the opening communicating with the chamber; a pressing member disposed on the opening of the grip, slightly protruding from the grip, and capable of moving closer to or further away from the grip; a brake unit having a trigger member disposed within the chamber of the grip, the trigger member being drivable to drive the brake unit to perform braking; and a conversion unit disposed within the chamber, one end connected to the pressing member and the other end connected to the trigger member, wherein when the pressing member drives the conversion unit, the conversion unit can drive the trigger member, causing the brake unit to perform braking action.

[0008] Accordingly, the pressing element is provided at the opening of the handle. The user can touch the pressing element by holding the handle, which can drive the pressing element to operate the conversion unit, thereby driving the brake unit to perform braking action. This can reduce the pressing distance during braking action. Furthermore, by providing the pressing element inside the handle, the user can operate the brake without opening their palm, which can reduce hand fatigue and burden. In addition, the user can brake without changing the position while holding the handle, which can speed up the braking action.

[0009] Preferably, the conversion unit is a rotating rod, which is centrally pivotally located inside the grip. One end of the rotating rod is configured as the pressing member, and the other end is in contact with the trigger member. When the pressing member presses down and drives the rotating rod to rotate, the other end of the rotating rod drives the trigger member to brake.

[0010] Preferably, the conversion unit is a gear set, which is pivotally mounted in the grip. The pressing member is provided with a pressing rack that meshes with the gear set. The pressing rack can drive the gear set to rotate. The trigger member is provided with a trigger rack that meshes with the gear set. The trigger rack is driven by the gear set to drive the braking unit to brake.

[0011] The brake grip structure provided by the present invention is easy to operate by means of the pressing member being disposed on the side of the grip, and can quickly drive the brake unit to perform braking action. Furthermore, because the pressing member is disposed on the outer ring side of the grip, the user can directly hold the grip, which is ergonomic, easy to operate, and does not require the user to keep their palm open for a long time, thus reducing riding discomfort.

Implementation Method

[0012] Please refer to Figures 1 and 2 for a preferred embodiment of the brake grip structure provided by the present invention, which includes:

[0013] A handle 10 has a centrally located chamber 11. The handle 10 can be mounted on vehicles such as bicycles, motorcycles, or balance bikes where direction can be controlled via the handle. The handle 10 has two ends, both of which are identical. The following description uses the structure of one side as an example, while the structure of the other side is identical. The handle 10 has an opening 12 around its outer circumference, which communicates with the chamber 11. An outer sleeve 13 is provided on the outer side of the handle 10.

[0014] A braking unit 20 is provided with a trigger 21 in the chamber 11 of the grip 10. The trigger 21 can be driven to drive the braking unit 20 to perform braking. In this embodiment, the braking unit 20 has a rope 22. The trigger 21 is provided with one end 211 at the end of the rope 22. The rope 22 can be pulled to displace a braking structure and generate a braking effect. The braking structure of the braking unit 20 is a conventional structure and will not be described in detail here. Any structure that achieves the braking effect through the traction of the rope 22 can be used in this embodiment. In addition, the braking unit can also be stopped by hydraulic pressure. This structure will be described in another embodiment.

[0015] A conversion unit 30 is disposed in the chamber 11 of the grip 10. In this embodiment, it is a rotating rod 31. The center of the rotating rod 31 is pivotally mounted in the chamber 11 with a pivot 311. One end of the rotating rod 31 is provided with a pressing member 312, and the other end is connected to the trigger member 21 of the braking unit 20. When the pressing member 312 is not under force, it is disposed at the opening 12 of the grip 10 and protrudes slightly from the outer circumference of the grip 10, that is, the outer sleeve 13 protrudes slightly. When the pressing member 312 is subjected to force, the force applied along the radial direction of the grip 10 can cause the pressing member 312 to drive the rotating rod 31 to rotate, so that the rotating rod 31 generates a pulling force on the trigger member 21 relative to the end of the pressing member 312, so that the braking unit 20 performs braking action.

[0016] Please refer to Figures 1 and 2. During riding, the user can place their palm directly on the handlebar 10 for easy gripping and directional control. The opening 12 protrudes slightly from the handlebar 10 because the pressing part 312 of the rotating rod 31 will protrude slightly. Therefore, the user can feel the position of the pressing part 312 from the outside of the handlebar 10 when gripping. Furthermore, because the grip diameter of the handlebar 10 is small, the user can grip it in a fist-like manner, which will not easily cause fatigue during long-term use. When braking, the user only needs to apply force with their fingers to press the position. The pressing member 312 on the grip 10 can drive the rotating rod 31 of the conversion unit 30 to rotate, and the rotating rod 31 rotates around the pivot 311, so that the end 211 of the trigger member 21 can drive the rope 22 to pull, so that the braking unit 20 can perform a braking action. In this way, the user's palm can maintain the original posture when riding or braking, without the need to switch temporarily. Just press the pressing member 312 to produce a braking effect. The operation is quick and can greatly reduce the situation of braking failure.

[0017] Please refer to Figures 3 and 4, which are the second preferred embodiment provided by the present invention. Its main structure is the same as that of the previous embodiment. The same parts are represented by the same symbols and will not be described again.

[0018] The brake unit 20 is equipped with a hydraulic pipe 23 inside the grip 10. A trigger 24 is provided at the end of the hydraulic pipe 23. The trigger 24 is a piston 241. When the piston 241 of the trigger 24 moves towards the hydraulic pipe 23, the piston 241 can pressurize the hydraulic oil inside the hydraulic pipe 23, so that the brake structure of the brake unit is pressurized by the hydraulic oil and a braking action is generated. When the rotating rod 31 rotates, it generates an actuation direction that pushes the trigger 24 towards the hydraulic pipe 23. This allows the piston 241 to pressurize the oil pressure in the hydraulic pipe 23. In addition, in order to ensure good contact between the piston 241 and the rotating rod 31, an auxiliary plate 313 is pivotally provided at the end of the rotating rod 31 that connects to the trigger member 24. The auxiliary plate 313 can abut against the side of the trigger member 24 and move with the rotating rod 31. When the user presses the pressing member 312, the rotating rod 31 will drive the auxiliary plate 313 to push the piston 241 of the trigger member 24 to pressurize the hydraulic pipe 23, so that the braking unit 20 can brake.

[0019] Please refer to Figures 5 and 6, which are the third preferred embodiment provided by the present invention. Its main structure is the same as that of the first embodiment. The same parts are represented by the same symbols and will not be described again.

[0020] The conversion unit 30 is a soft sphere 32, which is disposed inside the chamber 11. The soft sphere 32 can deform under force. The interior of the soft sphere 32 can contain air, water, or other fluids, or it can be made of a homogeneous sphere of rubber (plastic) with extensibility and deformability. A pressing member 321 is provided on the soft sphere 32 near the opening 12 of the handle 10. The pressing member 321 can press against the soft sphere. A force is applied radially to the handle 10, causing the soft ball 32 to be confined within the chamber 11 and deformed axially to the handle 10 after being subjected to the force applied by the pressing member 321. The rope 22 of the brake unit 20 is fixed to the side of the soft ball 32 by the end 211 of the trigger member 21, allowing the rope 22 to move with the deformation of the soft ball 32, thereby being pulled to produce a braking effect. When using the brake, the user holds the handle 10 on the outside and applies force to the pressing member 321 to perform the braking action, causing the pressing member 321 to exert a radial force along the handle 10, causing the soft ball 32 to deform axially to the handle 10, thereby actuating the trigger member 21 to perform the braking action.

[0021] Please refer to Figures 7 and 8, which are the fourth preferred embodiment provided by the present invention. Its main structure is the same as that of the previous embodiment. The same parts are represented by the same symbols and will not be described again.

[0022] When the soft ball 32 is combined with the hydraulic brake unit 20, the side of the soft ball 32 can abut against the piston 241 of the trigger member 24. The piston 241 can be provided with a support plate 242 at its end to increase the contact surface area between it and the soft ball 32. When the soft ball 32 is subjected to the radial force of the pressing member 312 along the handle 10 and deforms along the axial direction of the handle 10, the deformed part of the soft ball 32 can drive the piston 241 of the trigger member 24 to have a displacement that moves closer to the hydraulic pipe 23, so that the piston 241 can push the hydraulic oil in the hydraulic pipe 23 to form a pressurization action, so that the brake unit 20 can form a brake.

[0023] Please refer to Figures 9 and 10, which are the fifth preferred embodiment provided by the present invention. Its main structure is the same as that of the first embodiment. The same parts are represented by the same symbols and will not be described again.

[0024] The conversion unit 30 is a ramp block 33, which is housed in the chamber 11 of the grip 10. A pressing member 331 is provided on the ramp block 33 opposite to the opening 12, allowing the pressing member 331 to slightly protrude from the opening 12 of the grip 10. A ramp 332 is provided on one side of the ramp block 33 near the brake unit 20. In this embodiment, the piston 241 of the brake unit 20 abuts against the ramp 332. A ramp surface 243 is also provided on the piston 241 that contacts the ramp surface 332. The inclined surface 332 is inclined towards the opening 12. The closer the inclined surface 332 is to the opening 12, the closer it will be to the hydraulic pipe 23. Thus, when the user holds the handle 10 and wants to perform the braking action, as long as the user presses the pressing part 331 with his / her fingers, the inclined surface 33 will be displaced in the radial direction of the handle 10. This will cause the contact position between the inclined surface 332 and the piston 241 to gradually move closer to the hydraulic pipe 23, so that the piston 241 can pressurize the hydraulic oil in the hydraulic pipe 23, thereby causing the braking unit 20 to perform the braking action. In order to ensure that the inclined block 33 can return to its original position when no force is applied, four elastic elements 333 are provided at the bottom of the inclined block 33. When the inclined block 33 is subjected to the force of the pressing member 331, the elastic elements 333 will also be compressed and generate elastic force. When the pressing member 331 is not subjected to force, the elastic elements 333 will generate elastic restoring force and push the inclined block 33 back.

[0025] Please refer to Figures 11 and 12, which are the sixth preferred embodiment provided by the present invention. Its main structure is the same as that of the first embodiment. The same parts are represented by the same symbols and will not be described again.

[0026] The conversion unit 30 is a protrusion 34, which is disposed in the chamber 11. A pressing member 341 is disposed near the opening 12. A convex surface 342 is disposed on the other side of the protrusion 34 opposite to the pressing member 341. In this embodiment, the trigger member 21 of the braking unit 20 is a line segment 212, which is connected to the rope 22. The convex surface 342 abuts against the line segment 212. When no force is applied, the line segment 212 remains straight. When the user presses the pressing member 341, the pressing member 341 is subjected to force along the handle 10. During radial movement, the convex surface 342 presses against the line segment 212, causing the line segment 212 to deform. After deformation, the line segment 212 will drive the rope 22 closer to the conversion unit 30, thus forming a braking effect. In order to enable the protrusion 34 to quickly return to its original position after braking, four elastic elements 343 are provided on the protrusion 34. When the protrusion 34 is subjected to force, the elastic elements 343 will generate an elastic restoring force. When the protrusion 34 stops being subjected to force, the elastic elements 343 will push the protrusion 34 towards the opening 12, so that the conversion unit 30 can return to its original position.

[0027] Please refer to Figures 13 and 14, which are the seventh preferred embodiment provided by the present invention. Its main structure is the same as that of the first embodiment. The same parts are represented by the same symbols and will not be described again.

[0028] A conversion unit 40 is composed of a gear set 41, which has a gear disk 411; a pressing member 50, which has a pressing rack 51, which is disposed at the opening 12 of the grip 10 and can generate a displacement in the radial direction of the grip 10; a trigger rack 25, which is connected to the trigger member 21 and can drive the rope 22 to move; the pressing rack 51 and the gear disk 411 of the gear set 41 are respectively meshed with the gear disk 411. When the gear plate 411 rotates, the pressing rack 51 and the trigger rack 25 will operate simultaneously. In use, when the user's hand presses on the pressing member 50 and applies force, the pressing rack 51 will move radially, which will drive the gear plate 411 to rotate (clockwise in this embodiment). At the same time, the gear plate 411 will drive the trigger rack 25 to move away from the rope 22, which can form a pulling effect on the rope 22, causing the rope 22 to brake.

[0029] Please refer to Figures 15 and 16, which are the eighth preferred embodiment provided by the present invention. Its main structure is the same as that of the previous embodiment. The same parts are represented by the same symbols and will not be described again.

[0030] The trigger rack 25 is connected to the piston 241 of the trigger member 24, and the pressing rack 51 drives the gear plate 411 to rotate in a counterclockwise direction. Thus, when the pressing member 50 presses in the radial direction of the grip 10, the gear plate 411 will drive the trigger rack 25 to move towards the piston 241, thereby enabling the trigger rack 25 to drive the piston 241 to pressurize the hydraulic pipe, thus forming a braking effect.

[0031] Please refer to Figures 17 and 18, which are the ninth preferred embodiment provided by the present invention. Its main structure is the same as that of the previous embodiment. The same parts are represented by the same symbols and will not be described again.

[0032] The gear set 41 includes a first gear 412 and a second gear 413. The diameters of the first gear 412 and the second gear 413 are different. By changing the diameter, the travel distance between the pressing rack 51 and the trigger rack 25 can be changed. In this embodiment, the diameter of the first gear 412 is larger and the diameter of the second gear 413 is smaller. The pressing rack 51 meshes with the first gear 412, and the trigger rack 25 meshes with the second gear 413. When the pressing rack 51 drives the first gear 412, the second gear 413 can rotate synchronously. The second gear 413 can generate a larger operating force, which can increase the strength of the brake. In operation, the size ratio between the first gear 412 and the second gear 413 can be adjusted according to different needs, such as setting the first gear 412 as the smaller diameter and the second gear 413 as the larger diameter.

[0033] The brake grip structure provided by the present invention reduces the size of the opening for hand grip by setting the pressing member at the opening position of the grip, thereby avoiding discomfort during long-term riding. Furthermore, as long as the hand is placed on the grip, the braking action can be performed quickly, reducing reaction time and preventing accidents.

[0034] The above-described embodiments are merely illustrative of the technical means of the present invention and are not intended to limit it. Any equivalent modifications made to the present invention should be considered within the scope of protection of the present invention. The brake grip structure of the present invention is an original structure in this field and has improved practical effectiveness; therefore, this application is filed in accordance with the law.
