Embodiments of the present invention will be described below based on Figs. 1 to 2e. This description is not intended to limit the embodiments of the invention, but is an embodiment of the invention.

As shown in FIG. 1, a time difference pressure distribution output device 100 according to an embodiment of the present invention includes a pressure chamber member 1 including a sliding chamber portion 11 and a pressure connected to one end of the sliding chamber portion 11. The input portion 12, a pressure output portion 13 connected to the other end of the sliding chamber portion 11, and a time difference output portion 14 connected to the sliding chamber portion 11 between the pressure input portion 12 and the pressure output portion 13, pressure The input unit 12 is connected to a touch member B1, B2, the pressure output portion 13 is connected to a first actuator B3, the time difference output portion 14 is connected to a second actuator B4, and a pressure distribution member 2 is slidably disposed. The pressure input portion 12 is slidable between the pressure input portion 12 and the pressure output portion 13 in the sliding chamber portion 11 and is interposed between the pressure input portion 12 and the pressure output portion 13, wherein the pressure input portion 12 is coupled to the actuation member When B1 is triggered, a pressure P0 is applied to the sliding chamber portion 11, and the pressure distribution member 2 is pressed to slide toward the pressure output portion 13, so that the pressure output portion 13 generates a first actuation pressure Pa1 to the first actuator B3. , causing the first actuator B3 to actuate, sliding the pressure distribution member 2 to correspond to the slip When the position of the time difference output portion 14 of the cavity portion 11 is at least, the pressure input portion 12 is connected to the time difference output portion 14, and the time difference output portion 14 receives the pressure P2 applied from the pressure input portion 11, and generates a second pressure on the second actuator B4. The second actuating pressure Pa2 causes the second actuator B4 to act and has a time difference relative to the actuation of the first actuator B3.

As shown in Fig. 1, in the present embodiment, the time difference pressure distribution output device 100 is applied to a bicycle system of a bicycle B. The trigger members B1, B2 are a brake starter of the bicycle B (ie, the front wheel brake lever and the rear wheel brake lever), and the first actuator B3 is a brake actuator of the bicycle B (ie, the rear wheel brake) And the second actuator B4 is a brake actuator of the bicycle B (ie, the front wheel brake).

As shown in Fig. 1, in the present embodiment, the pressure chamber member 1 is an oil pressure chamber member, and the slip chamber portion 11 is filled with hydraulic oil to be pressurized or decompressed by the flow of the hydraulic oil. Of course, the present invention is not limited thereto, and the slip chamber portion 11 may be filled with a liquid other than the hydraulic oil, or may be filled with a gas. The structure of the pressure chamber member 1 is like a tee in the present embodiment, wherein the tube between the pressure input portion 12 and the pressure output portion 13 is preferably smooth without corners so that the pressure distribution member 2 can be in the tube body. Smoothly slipped.

As shown in Fig. 1, in the present embodiment, the pressure distributing member 2 functions as the same piston in the sliding chamber portion 11. The outer diameter of the pressure distribution member 2 is substantially equal to the inner diameter of the sliding chamber portion 11, and the sliding chamber portion 11 is substantially divided into three chambers, that is, a first chamber 11a located on the side of the pressure input portion 12, located A second chamber 11b on the pressure output portion 13 side and a third chamber 11c on the time difference output portion 14 side. The pressure P0 of the first chamber 11a is determined according to the input pressure of the pressure input portion 12 after the triggering members B1, B2 are triggered. The pressure P1 of the second chamber 11b is mainly determined by the volume change caused by the slip of the pressure distribution member 2. The pressure P2 of the third chamber 11c is substantially unaffected by the slip of the pressure distribution member 2, but in the case where the third chamber 11c is in communication with the first chamber 11a, directly along with the pressure input portion 12 The input pressure changes the size.

Next, the operation mode of the time difference pressure distribution output device of the present invention will be described with reference to Figs. 1 to 2e.

As shown in Fig. 2a, when either or both of the actuating members B1, B2 (Fig. 1) are touched, a signal S (e.g., pulling force of the brake line) is transmitted to the pressure input portion 12. . to That is, the pressure input portion 12 applies a pressure P0 (for example, air pressure or oil pressure) to the first chamber 11a of the slip chamber portion 11. As the pressure of the first chamber 11a rises, the pressure distribution member 2 slides toward the pressure output portion 13 due to the relatively low pressure P1 of the second chamber 11b. Thereby, the pressure P1 of the second chamber 11b rises, and the pressure output portion 13 generates a first actuation pressure Pa1 for the first actuator B3, so that the first actuator B3 is actuated, that is, the rear wheel of the bicycle B is made. Start driving.

As shown in FIG. 2b, the pressure distribution member 2 is continuously slid toward the pressure output portion 13 by the application pressure P0 of the pressure input portion 12. When the pressure distribution member 2 is slid to a position corresponding to the time difference output portion 14 of the slip chamber portion 11, the pressure input portion 12 is the communication time difference output portion 14, that is, the first chamber 11a communicates with the third chamber 11c. At this time, the third chamber 11c is gradually increased by the pressure P0 of the first chamber 11a, and the time difference output portion 14 generates a second actuation pressure Pa2 for the second actuator B4, so that the second actuator B4 is actuated, that is, the bicycle B front wheel starts to brake. As described above, by the action of the second actuator B4, there is a time difference with respect to the actuation of the first actuator B3, so that the bicycle B can smash the rear wheel and then the front wheel, and the safe braking can be performed correctly. Further, in the present embodiment, the sliding chamber portion 11 has an enlarged portion 15, and the chamber sectional area of the enlarged portion 15 is larger than the chambers at both end portions of the sliding chamber portion (i.e., the first chamber 11a and the first portion) The two chambers 11b) have a cross-sectional area. The time difference output portion 14 is connected to the enlarged portion 15 so that when the pressure distribution member 2 is slid to a position corresponding to the time difference output portion 14, the pressure input portion 12 is formed between the pressure distribution member 2 and the enlarged portion 15. The time difference output portion 14 is connected to a large gap.

In the present embodiment, the sliding chamber portion 11 further has a limiting member 16 disposed at one end of the sliding chamber portion 11 adjacent to the pressure output portion 13 and located between the pressure output portion 13 and the pressure distribution member 2, that is, Located in the second chamber 11b. The limiting member 16 is for blocking the pressure distributing member 2 at a predetermined position to limit the slip of the pressure distributing member to the pressure output portion 13. It should be noted that the limiting member 16 has a through hole 161 or other gas permeable structure to avoid the flow of gas or hydraulic oil that blocks the second chamber 11b. In addition, the limiting member 16 is preferably tunably disposed, and can be adjusted to determine the pressure distribution. The limit position of the member 2.

More specifically, as shown in FIG. 2c, the pressure distribution member 2 is continuously slid toward the pressure output portion 13 by the application pressure P0 of the pressure input portion 12, and then the slip is stopped by the abutment against the stopper 16. . In this case, the pressure P1 of the second chamber 11b does not increase any more, and the first actuation pressure Pa1 outputted by the pressure output portion 13 does not change anyway or the output is stopped depending on the design. On the other hand, the pressure P2 of the third chamber 11c continues to rise with the application pressure P0 of the pressure input portion 12, so that the second actuator B4 continues to operate. Such a design can make the first actuation pressure Pa1 and the second actuation pressure Pa2 not only have a time difference on the output, but also can achieve the effect of adjusting the magnitude of the individual output pressure. In the effect applied to the bicycle braking system, the time at which the first actuator B3 and the second actuator B4 start to act (brake) has a time difference, and finally the condition that the front wheel braking force is greater than the rear wheel braking force is completely Stop. Thereby, it is possible to prevent the situation in which the final brake force ratio of the front and rear wheels is incorrect and the parking cannot be effectively stopped.

Next, as shown in Fig. 2d, when the actuation members B1, B2 (Fig. 1) are released and the signal transmission is stopped, the pressure input portion 12 stops the pressing, and the pressure P0 of the first chamber 11a is gradually lowered to return to the original value. . When the pressure P0 of the first chamber 11a drops below the pressure P1 of the second chamber 11b, the pressure distribution member 2 will slip back until the pressure on both sides thereof reaches a balanced position.

As shown in Fig. 2e, when the pressure distributing member 2 is slid so that the first chamber 11a and the third chamber 11c are not in communication, the pressure P2 of the third chamber 11c may be larger than that of the first chamber 11a. The pressure P0 causes a pressure imbalance. Therefore, preferably, the pressure distribution member 2 has a back pressure passage 21 extending through the pressure distribution member 2. The two ends of the back pressure passage 21 are respectively located at a position corresponding to the time difference output portion 14 and corresponding to the pressure input portion 12, that is, both ends of the back pressure passage 21 are respectively communicated with the third chamber 11c and the first chamber. The chamber 11a presses the pressure P2 of the time difference output unit 14 back to the pressure input unit 12 through the pressure return passage 21. In addition, in the present embodiment, the back pressure channel 21 has a plurality of channel sections 211a, 211b, 211c, and 211d radially distributed, and the opening positions of the channel sections 211a, 211b, 211c, and 211d At a position corresponding to the time difference output portion 14, that is, communicating with the third chamber 11c. The pressure balance of the third chamber 11c and the first chamber 11a can be accelerated by the arrangement of the plurality of channel sections 211a, 211b, 211c, 211d.

In addition, in order to avoid undesired pressure leakage caused by the back pressure passage 21, the pressure distribution member 2 in this embodiment further has a shutter member 22 disposed on the back pressure passage 21, and the shutter member 22 is set to be a time difference output. The portion 14 opens unidirectionally toward the pressure input portion 12. In other words, in the case where the pressure P2 of the third chamber 11c is larger than that of the first chamber 11a, the shutter member 22 is opened, so that the third chamber 11c communicates with the first chamber 11a, and the pressure is restored to equilibrium (Fig. 2e) ). In the case where the pressure P0 of the first chamber 11a is larger than the third chamber 11c, the shutter member 22 closes the back pressure passage 21, and prevents the pressure P0 of the first chamber 11a from leaking to the third chamber via the back pressure passage 21. 11c.

With the above configuration, the time difference pressure distribution output device 100 of the present invention can output two actuation pressures having a time difference with respect to the braking system of the bicycle B, so that the safety of the front wheel and the front wheel can be correctly performed. Of course, the present invention is not limited thereto, and the time difference pressure distribution output device 100 can also be applied to time difference output control in other devices. Furthermore, the time difference pressure distribution output device 100 of the present invention generates an actuation pressure by the slip of the pressure distribution member 2, and the change in the actuation pressure has continuity, which drives the actuation of the actuator to be smoother, thereby reducing the cause. Malfunction or instability caused by drastic changes in output.

The above description is only for the preferred embodiment of the present invention, and those skilled in the art can make other improvements according to the above description, but these changes still belong to the inventive spirit of the present invention and the patents defined below.
