Description of the invention: [Technical field of the invention] The present invention relates to a method for operating a brake master cylinder and a hydraulic brake mechanism, and more particularly to an operation of a brake master cylinder and a hydraulic brake mechanism suitable for a high vibration environment. method. [First-hand technology] The first step of Figure 1 shows the conventional hydraulic brake mechanism. Among them, the hydraulic brake mechanism includes a brake master cylinder (1), a brake caliper (3), and a brake cylinder (2). The brake hose (2) is connected to the brake master cylinder (1) and the brake clamp (3) 〇 , please also refer to Fig. 2, which shows the internal structure of the broken line area (A) of the hydraulic brake mechanism of Fig. i. Among them, the cylinder (12) of the brake master cylinder (丨) has a plunger space for the plunger (13) to move therein. This plunger space can be divided into a first subspace (122) and a second subspace (123). The first subspace (122) communicates with the oil storage space (121) via the first passage (129), and the oil storage space (121) communicates with the second subspace (123) via the second passage (128), the second subspace (123) is connected to the brake oil pipe (2) via the main pump oil outlet (125), and the first one-way cup (14) and the second one-way cup (15) are mounted on the plunger (13), two skins The space created by the bowl and the cylinder (丨2) is the first subspace (122), and the second one-way cup (15) is located between the first passage (129) and the second passage (128). The function of the one-way cup is similar to that of the single valve, which only allows the vehicle oil to flow in one direction. For example, the second unidirectional cup (15) may allow the brake oil in the first subspace (122) to flow to the second subspace 0334-A21428TWF(N2) due to pressure changes; 94-TOP-30; itshen 1296245 ( 123), but the second subspace (123) brake oil cannot flow directly to the first subspace (122). One end of the plunger (13) is in contact with the abutting portion (m) of the handle (11), and the other end is provided with a spring (19) which abuts against the plunger (13) and the red body (12) Between the plunger (13) is pushed in the direction of the abutting portion (1Π). When the user grips the handle (11), the abutment portion (111) of the handle (Π) will push against the plunger (丨3), as shown in Fig. 3, so that the device is placed on the plunger (13). The first one-way cup (15) passes through the second passage (128), and the brake oil of the second sub-space (123) is sent to the brake caliper (3) via the master pump outlet (125) and the brake hose (2). The piston (32) and the brake shoe (33) in the brake caliper (3) are pushed to clamp the rotating brake disc (4) to generate a braking action. When the brake is terminated, the user releases the handle (11), the handle (11) abuts 4 (111) and the column base (13) sin spring (19) elastically returns to the pre-action position (ie, Figure 2) (33) The piston (32) is slightly pushed by the turning disc (4), and the excess brake oil is passed through the brake oil pipe (2), the main pump oil outlet (125), the second subspace (123), and the second passage. (128) Flow back to the oil storage space (121) to terminate the braking action. However, when the brake caliper (3) is operating in a high vibration environment, the brake shoe (33) will strike the piston (32) due to inertial vibration, causing the piston (32) to press the brake oil back to the oil storage space (121). If a brake is used, the brake master cylinder (丨) will need to supply more brake oil to the brake caliper (3) to generate the brake action, thus causing an increase in the stroke of the handle (11) and the plunger (13). SUMMARY OF THE INVENTION 0134-A21428TWF (N2); 94-TOP-30; jtshen 1296245 In view of the above, an object of the present invention is to solve the above problems and provide a method for operating a brake master cylinder and a hydraulic brake mechanism, wherein a brake master cylinder The utility model comprises a cylinder, a plunger, a first one-way cup, a second one-way cup, and a third one-way cup. The cylinder body contains brake oil, and the cylinder has a storage oil space, a plunger space, and a master pump outlet. The plunger is movably disposed within the plunger space. The first one-way cup, the second one-way cup, and the third one-way cup are all disposed on the plunger, the third one-way cup is close to the main pump outlet, and the third cup is set in the direction and the third 1. The second one-way cup is oppositely disposed, wherein the first, second, and third one-way cups are disposed such that the first and second one-way cups of the brake oil can pass through the second one-way skin The bowl flows between the second and third one-way cups, but the brake oil between the second and third one-way cups cannot flow to the first and second ones via the second one-way cup Between the cups. When the brake caliper of the hydraulic brake mechanism is vibrated, the brake of the second unidirectional cup can prevent the brake oil in the brake caliper from flowing to the brake master cylinder, thereby solving the problem that the handle and the plunger increase the actuation stroke due to the high vibration environment. . The above described objects, features, and advantages of the present invention will be more apparent from the description of the preferred embodiments. [Embodiment] First Embodiment: Referring to Fig. 4, the same portions as those of the prior art are given the same reference numerals and the description is omitted. In the present embodiment, the configurations of the plunger (135) and the cylinder (125) are changed. In the plunger (13') portion, the second one-way cup (15) is associated with 0134-A21428TWF (N2); 94-TOP-30; itshen. 1296245 A third one-way cup (Ιό) is added between the springs (19), and the third one-way cup (16) direction is opposite to the first one-way cup (14) and the second one-way cup (15) The ancestors, the second one-way cup (15) and the third one-way cup (16) and the red body (12,) are used to create a space for the third sub-space (124). In the cylinder (12') portion, the first passage (129) and the second passage (128) are located between the first one-way cup (14) and the second one-way cup (15). A fourth channel (126) and a third channel (127) are added between the second subspace (123') and the master pump outlet (125). As shown in Fig. 5, the urging portion (111) of the handle (11) pushes the column #(135) while the second unidirectional cup (15) pushes the brake oil of the third subspace (124). The third subspace (124) is a confined space, so that the second subspace (123,) brake oil flows to the brake caliper (3) via the fourth passage (126) or the third passage (127) to generate a braking action. When the brake is terminated, the handle (11) and the plunger (13) are elastically returned to the pre-actuation position by the spring (19,), which is shown in Fig. 4, because the third one-way cup (16) has an anti-soil effect. The brake fluid of the third subspace (124) cannot flow to the second subspace (123,), so that the second subspace (123,) generates a negative pressure, forcibly sucking the brake oil back by the brake caliper (3), so that the brake caliper is clamped. (3) Lift the brakes. The right brake car card sweet (3) is working in the south vibration environment. Due to the blocking of the second one-way cup (15), the brake oil of the brake caliper (7) cannot be returned due to the tapping of the brake piece (33), and the handle is solved ( 11) The problem that the plunger (13) increases the actuation stroke due to the high vibration environment. If the brake piece (33) wears after use, when the vehicle is braked, as shown in Fig. 6, the third one-way cup (16) will pass through the fourth passage (126), at this time the third sub-space (124) Brake oil flows through the fourth passage (126) to the main pump outlet 0134-A21428TWF (N2); 94-T〇P~30; itshen 1296245

When the brake is terminated, the handle (11) and the plunger (13,) are spring-loaded (19,) to return to the pre-action position 'because the third sub-space (124) and the main pump outlet (丨25) are four channels. (126) in the same way, at this time, the brother-child space (122) brake oil will flow to the third sub-space (124) via the second one-way cup (15) due to the pressure difference, when the third one-way cup (16) passes The fourth channel (126), at this time, the third subspace (124) returns to the initial confined space, causing the second subspace (123) to generate a negative pressure, forcibly sucking the brake oil back by the brake button (3), so that Brake calipers (3) release the brakes. After using for a period of time, if the brake piece needs to be replaced, as shown in Fig. 7, the handle (11) is removed, and the plunger (13') is urged by the spring (19,) to the stopper (18). The member (18) is disposed at the port of the plunger space of the cylinder (12,) for preventing the plunger (13,) from being disengaged from the cylinder (12,). At this time, the second one-way cup (15) passes through the second passage (128), so that the third sub-space (124) is kept open to the oil storage space (121) via the second passage (128), and the brake caliper (3) is provided.

Second Embodiment: Please refer to Fig. 8, in which the same portions as those in the first embodiment are given the same reference numerals and the description will be omitted. In this embodiment, the fourth channel (126) and the third channel (127) are abolished, and the master pump outlet (125) is directly connected to the second subspace (123') in the third subspace ( 124) a slope area (120) is added at the junction of the end of the active range and the second subspace (123,), thereby making the plunger space 0334-A21428TWF(N2); 94-TOP-30; itshen 10 1296245 have different diameters . - As shown in Figure 9, the thrust portion (111) of the handle (11) pushes the column base (13), and the second one-way cup (15) pushes the brake oil of the third subspace (I%). Since the third subspace (124) is a closed space at this time, the second subspace (123') brake oil flows to the brake caliper (3) via the master pump outlet (125), thereby generating a braking action.
煞車終止,手柄(11)及柱塞(13,)受彈簧(19,)彈力回到 作動4位置,此時因第三單向皮碗(16)的阻擋,第三子空 間(124)之煞車油無法流向第二子空間(123,),於是第二子 空間(123’)產生負壓,強制將煞車油由煞車卡鉗(3户及回, 使煞車卡鉗(3)解除煞車。 若煞車卡鉗(3)處於高振環境下工作,由於第二單向皮 碗(15)的阻擋,使煞車卡鉗(3)的煞車油無法因煞車片(33) 的敲擊而回流,解決手柄(11)與柱塞(丨3,)因高振環境使作 動行程增加的問題。When the brake is terminated, the handle (11) and the plunger (13,) are spring-returned by the spring (19,) to the position of the actuation 4, and the third sub-space (124) is blocked by the third one-way cup (16). The brake oil cannot flow to the second sub-space (123,), so the second sub-space (123') generates a negative pressure, forcibly braking the brake oil from the brake caliper (3 households and back, so that the brake caliper (3) is released. The caliper (3) works in a high-vibration environment. Due to the blocking of the second one-way cup (15), the brake oil of the brake caliper (3) cannot be retracted due to the tapping of the brake piece (33), and the handle is solved (11). ) The problem with the plunger (丨3,) increasing the actuation stroke due to the high vibration environment.
