Description

自行車之防鎖死煞車機構Anti-lock brake mechanism for bicycle

本發明係關於一種自行車之防鎖死煞車機構,特別是一種具有位於油壓調節缸內之磁力產生件的自行車之防鎖死煞車機構。The present invention relates to an anti-lock braking mechanism for bicycles, in particular to an anti-lock braking mechanism for bicycles with a magnetic force generator located in an oil pressure regulating cylinder.

隨著目前社會上運動的風氣越來越來普及,帶動了大眾透過騎乘自行車來達到運動及休閒的目的。因此,為了吸引消費者購買適用於登山或競速的高階自型車,或是供一般大眾休閒娛樂的低階自行車,廠商在設計自行車時,除了著重在改善自行車的騎乘感跟視覺感之外,對於騎乘自行車之安全性亦是重點精進項目之一。With the increasing popularity of sports in the current society, it has driven the public to achieve sports and leisure goals by riding bicycles. Therefore, in order to attract consumers to buy high-end self-propelled bicycles suitable for mountaineering or racing, or low-end bicycles for general public leisure and entertainment, when designing bicycles, manufacturers focus on improving the riding and visual sense of the bicycle. In addition, the safety of riding a bicycle is also one of the key projects.

以與安全最相關的煞車來說,目前業界已發展出將防鎖死煞車系統加裝於自行車上,以避免車輪在煞車時鎖死而產生打滑的現象,而提升自行車煞車時的安全性。一般而言,防鎖死煞車系統是藉由二活塞的外徑差異,使得二活塞在調節缸之調節腔室移動的過程中產生洩壓空間,來達到車輪防鎖死的目的。但,在現有的防鎖死煞車系統中,讓二活塞移動的驅動組件通常為設置於調節缸外部之一側,使得整體防鎖死煞車系統的長度過長,而影響整體自行車的外觀。In terms of braking, which is most relevant to safety, the industry has developed an anti-lock braking system to be installed on bicycles to prevent wheels from locking and slipping during braking, and to improve bicycle braking safety. Generally speaking, the anti-lock braking system uses the difference in the outer diameters of the two pistons to create a pressure relief space during the movement of the adjustment chamber of the adjustment cylinder to achieve the purpose of preventing the wheels from locking up. However, in the existing anti-lock braking system, the driving component that allows the two pistons to move is usually arranged on one side of the outside of the adjusting cylinder, so that the length of the overall anti-lock braking system is too long, which affects the overall appearance of the bicycle.

本發明在於提供一種自行車之防鎖死煞車機構,藉以解決先前技術中整體防鎖死煞車系統的長度過長影響整體自行車的外觀的問題。The present invention is to provide an anti-lock braking mechanism for bicycles, so as to solve the problem that the length of the overall anti-lock braking system in the prior art affects the appearance of the overall bicycle.

本發明之一實施例所揭露之一種自行車之防鎖死煞車機構,包含一油壓調節缸、一第一活塞、一第二活塞、一驅動件及一磁力產生件。油壓調節缸具有一油壓調節槽、一入油通道、一出油通道及一容置空間。入油通道、出油通道及容置空間分別連通油壓調節槽。第一活塞可移動地位於油壓調節槽。第一活塞具有一第一油路,第一油路連通入油通道。第二活塞可移動地位於油壓調節槽,且第一活塞的外徑大於第二活塞的外徑。驅動件可移動地位於容置空間且連接第二活塞。磁力產生件設置於容置空間內並環繞驅動件。當磁力產生件被通電時,磁力產生件產生一磁推力於驅動件,以令驅動件帶動第二活塞推抵第一活塞,而阻絕第一油路及油壓調節槽的連通關係,並於油壓調節槽內產生一洩壓容積。An anti-lock braking mechanism for a bicycle disclosed in an embodiment of the present invention includes an oil pressure regulating cylinder, a first piston, a second piston, a driving member and a magnetic force generating member. The oil pressure adjusting cylinder has an oil pressure adjusting groove, an oil inlet passage, an oil outlet passage and an accommodation space. The oil inlet passage, the oil outlet passage and the accommodating space are respectively connected with the oil pressure regulating groove. The first piston is movably located in the oil pressure regulating groove. The first piston has a first oil passage, and the first oil passage communicates with the oil inlet passage. The second piston is movably located in the oil pressure regulating groove, and the outer diameter of the first piston is larger than the outer diameter of the second piston. The driving member is movably located in the accommodating space and connected to the second piston. The magnetic force generating element is arranged in the containing space and surrounds the driving element. When the magnetic force generating member is energized, the magnetic force generating member generates a magnetic thrust on the driving member, so that the driving member drives the second piston to push against the first piston, thereby blocking the communication relationship between the first oil circuit and the oil pressure regulating groove, and A pressure relief volume is generated in the oil pressure regulating tank.

根據上述實施例所揭露的自行車之防鎖死煞車機構,由於讓驅動件帶動第二活塞移動的磁力產生件是設置於油壓調節缸的容置空間內,且更進一步設置成環繞驅動件,故除了使得防鎖死煞車機構的一體性提升外,還縮短了整體防鎖死煞車機構的長度,進而增加了具有此防鎖死煞車機構的自行車之外觀的美觀性。According to the anti-lock braking mechanism for bicycles disclosed in the above embodiments, since the magnetic force generating member that allows the driving member to drive the second piston to move is arranged in the accommodating space of the oil pressure regulating cylinder, and is further arranged to surround the driving member, Therefore, in addition to improving the integrity of the anti-lock braking mechanism, the length of the overall anti-lock braking mechanism is also shortened, thereby increasing the appearance of the bicycle with the anti-lock braking mechanism.

以上關於本發明內容的說明及以下實施方式的說明係用以示範與解釋本發明的原理,並且提供本發明的專利申請範圍更進一步的解釋。The above description of the content of the present invention and the description of the following embodiments are used to demonstrate and explain the principle of the present invention and provide a further explanation of the scope of the patent application of the present invention.

When the electromagnetic coil 62 is energized, the electromagnetic coil 62 will generate a magnetic thrust, and this magnetic thrust will act on the flange of the drive member 50 via the body portion 11 of the oil pressure regulating cylinder 10 and the magnetic permeable slope 72 of the permeable plate 70 The second piston 30 is moved from an initial position to a closed position, and then moved from the closed position to a pressure relief position. In other words, the closed position is between the initial position and the pressure relief position.

接著,如圖3、4、5所示,當第二活塞30位於初始位置時,第一活塞20抵靠於止擋面1113,且第一活塞20與第二活塞30相分離。此時,第一油路21及第二油路31透過油壓調節槽111連通出油通道112。在這樣的情況下,當使用者按壓油壓煞車把手以進行煞車時,油壓煞車把手會產生油壓,且此油壓會經由入油通道121、第一油路21、油壓調節槽111及出油通道112傳遞至油壓卡鉗,使得油壓卡鉗夾緊設置於自行車之車輪的煞車碟片,來讓自行車煞車。Next, as shown in FIGS. 3, 4 and 5, when the second piston 30 is in the initial position, the first piston 20 abuts the stop surface 1113, and the first piston 20 and the second piston 30 are separated. At this time, the first oil passage 21 and the second oil passage 31 communicate with the oil outlet passage 112 through the oil pressure regulating groove 111. In this case, when the user presses the hydraulic brake handle to brake, the hydraulic brake handle will generate oil pressure, and this oil pressure will pass through the oil inlet channel 121, the first oil passage 21, and the oil pressure regulating groove 111 And the oil outlet passage 112 is transmitted to the hydraulic caliper, so that the hydraulic caliper clamps the brake disc provided on the wheel of the bicycle to brake the bicycle.

在本實施例中,由於第一油路21貫穿第一活塞20的相對二端,且第一活塞20之相對二端的外徑D1、D2相等,故油壓作用於第一活塞20之相對二端的力會相等,而使第一活塞20處於力平衡狀態,而不會位移。In this embodiment, since the first oil passage 21 penetrates the opposite ends of the first piston 20, and the outer diameters D1 and D2 of the opposite ends of the first piston 20 are equal, the oil pressure acts on the opposite ends of the first piston 20. The forces at the ends will be equal, so that the first piston 20 is in a force balance state without displacement.

此外,由於第二活塞30之外徑D3略小於儲油腔室56的寬度W6,故油壓作用於第二活塞30鄰近驅動件50之一端的力會大於油壓作用於第二活塞30遠離驅動件50之一端的力,而使油壓作用於第二活塞30之相對二端的力不平衡,但磁性件100作用於驅動件50的磁力仍足以讓第二活塞30維持在初始位置。在其他實施例中,若儲油腔室的寬度再更大於第二活塞之外徑,則需要磁力較強的磁性件,來讓第二活塞維持在初始位置。In addition, since the outer diameter D3 of the second piston 30 is slightly smaller than the width W6 of the oil storage chamber 56, the oil pressure acting on the end of the second piston 30 adjacent to the driving member 50 will be greater than the oil pressure acting on the second piston 30 away from The force of one end of the driving member 50 makes the oil pressure acting on the opposite ends of the second piston 30 unbalanced, but the magnetic force of the magnetic member 100 acting on the driving member 50 is still sufficient to maintain the second piston 30 in the initial position. In other embodiments, if the width of the oil storage chamber is larger than the outer diameter of the second piston, a magnetic member with stronger magnetic force is required to maintain the second piston in the initial position.

當自行車的感測器偵測到自行車之車輪於煞車時發生鎖死的狀況時,電路板110會讓電磁線圈62被通電,使得電磁線圈62產生磁推力。此磁推力會經由油壓調節缸10的本體部11及導磁板70作用在驅動件50,而使驅動件50克服磁性件100的磁吸力而帶動第二活塞30從初始位置移動至封閉位置。請一併參閱圖6及圖7。圖6為圖4之第二活塞位於封閉位置的剖視示意圖。圖7為圖6的局部放大圖。When the bicycle sensor detects that the bicycle wheel is locked during braking, the circuit board 110 will cause the solenoid 62 to be energized, so that the solenoid 62 generates magnetic thrust. This magnetic thrust will act on the driving member 50 through the body 11 of the hydraulic adjusting cylinder 10 and the magnetic conductive plate 70, so that the driving member 50 overcomes the magnetic attraction force of the magnetic member 100 and drives the second piston 30 to move from the initial position to the closed position . Please refer to Figure 6 and Figure 7 together. 6 is a schematic cross-sectional view of the second piston of FIG. 4 in a closed position. Fig. 7 is a partial enlarged view of Fig. 6.

當第二活塞30位於封閉位置時,第二活塞30抵靠第一活塞20,以令第二油路31直接銜接第一油路21,以阻絕第一油路21與出油通道112的連通關係,並在油壓調節槽111會產生一飽壓容積A1。飽壓容積A1即為第一活塞20、第二活塞30及本體部11位於油壓調節槽111內之壁面之間的空間。When the second piston 30 is in the closed position, the second piston 30 abuts against the first piston 20, so that the second oil passage 31 directly connects with the first oil passage 21 to block the communication between the first oil passage 21 and the oil outlet passage 112 Relationship, and a saturated volume A1 is generated in the oil pressure regulating groove 111. The saturated volume A1 is the space between the walls of the first piston 20, the second piston 30, and the body portion 11 in the oil pressure regulating groove 111.

由於第二油路31、連通油路53及儲油腔室56彼此相連通,故油壓可作用於第二活塞30的相對二端,而產生部分力相銷的效果。因此,相較於推動無第二油路的第二活塞所需的磁推力,本實施例讓驅動件50帶動第二活塞30移動所需的磁推力即較低,故可相對節省通電電磁線圈62的電力。Since the second oil passage 31, the communicating oil passage 53 and the oil storage chamber 56 are in communication with each other, the oil pressure can act on the two opposite ends of the second piston 30 to produce a partial force-pinning effect. Therefore, compared with the magnetic thrust required to push the second piston without the second oil circuit, the magnetic thrust required by the driving member 50 to drive the second piston 30 to move in this embodiment is lower, so the energized solenoid can be relatively saved. 62 electricity.

此外,藉由儲油腔室56的寬度W6略大於第二活塞30之外徑D3的設置,可讓油壓作用於第二活塞30鄰近驅動件50之一端的力大於油壓作用於第二活塞30遠離驅動件50之一端的力,而提供第二活塞30朝第一活塞20移動的助力,故可減少電磁線圈62作用於驅動件50的磁推力,而進一步節省通電電磁線圈62的電力。但,儲油腔室56的寬度W6不限於大於第二活塞30之外徑D3。在其他實施例中,儲油腔室的寬度可等於第二活塞之外徑。In addition, by setting the width W6 of the oil storage chamber 56 slightly larger than the outer diameter D3 of the second piston 30, the force of the oil pressure acting on the end of the second piston 30 adjacent to the driving member 50 can be greater than that of the oil pressure acting on the second piston 30. The force of the piston 30 away from one end of the driving part 50 provides assisting force for the movement of the second piston 30 toward the first piston 20, so the magnetic thrust of the solenoid 62 acting on the driving part 50 can be reduced, and the power of the energized solenoid 62 can be further saved . However, the width W6 of the oil storage chamber 56 is not limited to be larger than the outer diameter D3 of the second piston 30. In other embodiments, the width of the oil storage chamber may be equal to the outer diameter of the second piston.

另外,由於第一活塞20的相對二端為力平衡的狀態,故第二活塞30在從初始位置移動至封閉位置的過程中,第一活塞20不會因第二活塞30的移動而產生位移。In addition, since the opposite ends of the first piston 20 are in a state of force balance, the first piston 20 will not be displaced due to the movement of the second piston 30 when the second piston 30 moves from the initial position to the closed position. .

接著,請參閱圖8及圖9。圖8為圖4之第二活塞位於洩壓位置的剖視示意圖。圖9為圖7的局部放大圖。Next, please refer to Figure 8 and Figure 9. Fig. 8 is a schematic cross-sectional view of the second piston of Fig. 4 at a pressure relief position. Fig. 9 is a partial enlarged view of Fig. 7.

接著,如圖8及圖9所示,驅動件50繼續推動第二活塞30,以令第二活塞30從封閉位置滑動至洩壓位置,並推動第一活塞20朝入油通道121移動一距離。當第二活塞30位於洩壓位置時,第一活塞20會壓縮彈性件40並抵靠於止擋面122,且在油壓調節槽111內會產生大於飽壓容積A1的一洩壓容積A2。Next, as shown in FIGS. 8 and 9, the driving member 50 continues to push the second piston 30 so that the second piston 30 slides from the closed position to the pressure relief position, and pushes the first piston 20 to move a distance toward the oil inlet channel 121 . When the second piston 30 is in the pressure relief position, the first piston 20 will compress the elastic member 40 and abut against the stop surface 122, and a pressure relief volume A2 greater than the saturated volume A1 will be generated in the oil pressure regulating groove 111 .

由於第一活塞20的外徑D1大於第二活塞30的外徑D3,故在第二活塞30從封閉位置移動至洩壓位置的過程中,移動的第一活塞20在油壓調節槽111之寬徑段1111所讓出來的空間會大於第二活塞30在油壓調節槽111之寬徑段1111所侵占的空間。因此,當第二活塞30移動至洩壓位置時,第一活塞20、第二活塞30及本體部11位於油壓調節槽111內之壁面所形成的洩壓容積A2會大於飽壓容積A1。Since the outer diameter D1 of the first piston 20 is greater than the outer diameter D3 of the second piston 30, when the second piston 30 moves from the closed position to the pressure relief position, the moving first piston 20 is positioned between the oil pressure regulating groove 111 The space allowed by the wide diameter section 1111 is larger than the space occupied by the second piston 30 in the wide diameter section 1111 of the oil pressure regulating groove 111. Therefore, when the second piston 30 moves to the pressure relief position, the pressure relief volume A2 formed by the wall surfaces of the first piston 20, the second piston 30 and the body portion 11 in the oil pressure regulating groove 111 will be greater than the saturated volume A1.

由此可知,藉由寬徑段1111及不同外徑大小的第一活塞20及第二活塞30之搭配,可讓第二活塞30從封閉位置移動至洩壓位置的過程中,增加容納煞車油的空間,故降低了出油通道112內的油壓。因此,煞車卡鉗可稍微放鬆來讓自行車之車輪恢復滾動,以防止自行車車輪產生滑動,進而提升自行車的煞車安全性。It can be seen that the combination of the wide-diameter section 1111 and the first piston 20 and the second piston 30 with different outer diameters can allow the second piston 30 to move from the closed position to the pressure relief position to increase the capacity of the brake fluid. Therefore, the oil pressure in the oil outlet channel 112 is reduced. Therefore, the brake calipers can be slightly relaxed to allow the wheels of the bicycle to resume rolling, so as to prevent the wheels of the bicycle from slipping, thereby improving the safety of the bicycle.

此外,由於第一活塞20之相對二端處於力平衡狀態,故在第二活塞30推動第一活塞20一同移動的過程中,第二活塞30僅需克服油壓作用於第一活塞20及第二活塞30互相遠離之一端之力的差值、磁性件100的磁力及彈性件40的彈力,故可減少電磁線圈62作用於驅動件50的磁推力,而節省通電電磁線圈62的電力。In addition, since the opposite ends of the first piston 20 are in a state of force balance, the second piston 30 only needs to overcome the oil pressure to act on the first piston 20 and the first piston 20 while the second piston 30 pushes the first piston 20 to move together. The difference between the force at one end of the two pistons 30 away from each other, the magnetic force of the magnetic member 100 and the elastic force of the elastic member 40 can reduce the magnetic thrust of the electromagnetic coil 62 acting on the driving member 50 and save the power of the energized electromagnetic coil 62.

再者,藉由第一活塞20遠離第二活塞30之一端的外徑D2微大於儲油腔室56的寬度W6之設置,可減輕在第一活塞20及第二活塞30一同移動的情況下,油壓作用於第一活塞20及第二活塞30互相遠離之一端之力的差值所造成之自行車之防鎖死煞車機構1震動的問題。Furthermore, by setting the outer diameter D2 of the end of the first piston 20 away from the second piston 30 to be slightly larger than the width W6 of the oil storage chamber 56, the situation that the first piston 20 and the second piston 30 move together can be reduced , The problem of the vibration of the anti-lock brake mechanism 1 of the bicycle caused by the difference in the force between the first piston 20 and the second piston 30 at one end of the distance from each other by the oil pressure.

當偵測器偵測到自行車的車輪開始滾動後,電路板110即會停止通電電磁線圈62。此時,原本推動驅動件50的磁推力即消失,故油壓作用於第一活塞20及第二活塞30互相遠離之一端之力的差值、彈性件40施予第一活塞20的彈力及磁性件100施予驅動件50的磁力分別會帶動第一活塞20、第二活塞30及驅動件50復位,而令第一活塞20抵靠止擋面1113且第二活塞30回到初始位置。如此一來,第一油路21即又與出油通道112相連通,使得油壓又可傳遞到至煞車卡鉗,以繼續進行煞車。當偵測器又偵測到自行車的車輪鎖死時,則在重複進行上述步驟,直到自行車煞車結束。When the detector detects that the wheel of the bicycle starts to roll, the circuit board 110 stops energizing the solenoid 62. At this time, the magnetic thrust that originally pushed the driving member 50 disappears, so the difference between the forces acting on the first piston 20 and the second piston 30 to move away from each other by the oil pressure, the elastic force exerted by the elastic member 40 on the first piston 20, and The magnetic force exerted by the magnetic member 100 on the driving member 50 will respectively drive the first piston 20, the second piston 30 and the driving member 50 to reset, so that the first piston 20 abuts the stop surface 1113 and the second piston 30 returns to the initial position. In this way, the first oil passage 21 is in communication with the oil outlet passage 112, so that the oil pressure can be transmitted to the brake calipers to continue braking. When the detector detects that the wheels of the bicycle are locked, the above steps are repeated until the bicycle is braked.

在本實施例中,第一活塞20遠離第二活塞30之一端的外徑D2並不限於微大於儲油腔室56的寬度W6。在其他實施例中,第一活塞遠離第二活塞之一端的外徑可等於或小於儲油腔室的寬度。在這樣的情況下,雖然可減少一同移動第一活塞及第二活塞所需的磁推力,但會導致後續讓第一活塞回位的力量不足,故需增加彈性件的彈性係數來幫助第一活塞回位。In this embodiment, the outer diameter D2 of the end of the first piston 20 away from the second piston 30 is not limited to be slightly larger than the width W6 of the oil storage chamber 56. In other embodiments, the outer diameter of the end of the first piston away from the second piston may be equal to or smaller than the width of the oil storage chamber. In this case, although the magnetic thrust required to move the first piston and the second piston together can be reduced, it will result in insufficient force for the subsequent return of the first piston. Therefore, the elastic coefficient of the elastic element needs to be increased to help the first piston. The piston returns to position.

根據上述實施例所揭露的自行車之防鎖死煞車機構,由於讓驅動件帶動第二活塞移動的磁力產生件是設置於油壓調節缸的容置空間內,且更進一步設置成環繞驅動件,故除了使得防鎖死煞車機構的一體性提升外,還縮短了整體防鎖死煞車機構的長度,進而增加了具有此防鎖死煞車機構的自行車之外觀的美觀性。According to the anti-lock braking mechanism for bicycles disclosed in the above embodiments, since the magnetic force generating member that allows the driving member to drive the second piston to move is arranged in the accommodating space of the oil pressure regulating cylinder, and is further arranged to surround the driving member, Therefore, in addition to improving the integrity of the anti-lock braking mechanism, the length of the overall anti-lock braking mechanism is also shortened, thereby increasing the appearance of the bicycle with the anti-lock braking mechanism.

此外,藉由寬徑段、不同外徑大小的第一活塞及第二活塞之搭配,可讓第二活塞從封閉位置移動至洩壓位置的過程中,增加容納煞車油的空間,故降低了出油通道內的油壓。因此,煞車卡鉗可稍微放鬆來讓自行車之車輪恢復滾動,以防止自行車車輪產生滑動,進而提升自行車的煞車安全性。In addition, through the combination of the first piston and the second piston with a wide diameter section and different outer diameters, the second piston can be moved from the closed position to the pressure relief position, increasing the space for accommodating the brake fluid, thus reducing The oil pressure in the oil outlet channel. Therefore, the brake calipers can be slightly relaxed to allow the wheels of the bicycle to resume rolling, so as to prevent the wheels of the bicycle from slipping, thereby improving the safety of the bicycle.

再者,由於第二油路、連通油路及儲油腔室彼此相連通,故油壓可作用於第二活塞的相對二端,而產生部分力相銷的效果。因此,相較於推動無第二油路的第二活塞所需的磁推力,上述實施例讓驅動件帶動第二活塞移動所需的磁推力即較低,故可相對節省通電電磁線圈的電力。Furthermore, since the second oil passage, the communicating oil passage and the oil storage chamber are in communication with each other, the oil pressure can act on the two opposite ends of the second piston to produce a partial force-pinning effect. Therefore, compared with the magnetic thrust required to push the second piston without the second oil circuit, the magnetic thrust required by the driving member to drive the second piston to move in the above embodiment is lower, so the power of the energized solenoid can be relatively saved. .

另外,藉由儲油腔室的寬度略大於第二活塞之外徑的設置,可油壓作用於第二活塞鄰近驅動件之一端的力大於油壓作用於第二活塞遠離驅動件之一端的力,而提供第二活塞朝第一活塞移動的助力,故可減少電磁線圈作用於驅動件的磁推力,而進一步節省通電電磁線圈的電力。In addition, with the arrangement that the width of the oil storage chamber is slightly larger than the outer diameter of the second piston, the force that can be applied by oil pressure to the end of the second piston adjacent to the driving member is greater than the force applied to the end of the second piston far away from the driving member Therefore, it can reduce the magnetic thrust exerted by the electromagnetic coil on the driving part and further save the power of the energized electromagnetic coil.

且,由於第一活塞之相對二端處於力平衡狀態,故在第二活塞推動第一活塞一同移動的過程中,第二活塞僅需克服油壓作用於第一活塞及第二活塞互相遠離之一端之力的差值、磁性件的磁力及彈性件的彈力,故可減少電磁線圈作用於驅動件的磁推力,而節省通電電磁線圈的電力。如此一來,使得自行車之防鎖死煞車機構具有較佳的機械效益(mechanical advantage)。Moreover, since the opposite ends of the first piston are in a state of force balance, the second piston only needs to overcome the oil pressure to act on the first piston and the second piston to move away from each other when the second piston pushes the first piston to move together. The difference between the force at one end, the magnetic force of the magnetic member and the elastic force of the elastic member can reduce the magnetic thrust of the electromagnetic coil acting on the driving member and save the power of the energized electromagnetic coil. In this way, the anti-lock braking mechanism of the bicycle has a better mechanical advantage.
