Description

Technical Field

[0001] The utility model relates to the technical field of oil pumps for cycling vehicles, and in particular to a brake oil pump conversion device and a cycling vehicle. Background Art

[0002] The hydraulic brake system of bicycles is popular because of its high efficiency, stability and easy maintenance. In this type of brake system, the design of the oil storage tank of the brake pump conversion device is very important.

[0049] Reference Figure 1-Figure 10 A brake oil pump conversion device, comprising: a housing 1-3, a first oil tank 21, a second oil tank 22, a first oil cylinder 11, a second oil cylinder 12, a first connecting oil path 13, a second connecting oil path 14, a first oil outlet oil path 15, a second oil outlet oil path 16, a first piston 111, a second piston 121, and a first driving member 112 and a second driving member 122 partially disposed in the housing 1-3;

[0050] Reference Figure 5 , the first oil tank 21 is connected to the first oil cylinder 11 through the first connecting oil path 13;

[0051] The first piston 111 is disposed in the first oil cylinder 11, and the first driving member 112 is fixedly connected to the first piston 111;

[0052] The first oil outlet passage 15 is in communication with the first oil cylinder 11, and the first oil outlet passage 15 is connected to a first disc brake unit (not shown in the figure), and the first disc brake unit is controlled by the pressure of the first oil cylinder 11;

[0053] Reference Figure 4 , the second oil tank 22 is connected to the second oil cylinder 12 through the second connecting oil passage 14;

[0054] Along the axial direction of the first oil cylinder 11, the first connecting oil passage 13 and the first oil outlet oil passage 15 are staggered.

[0055] The second piston 121 is disposed in the second oil cylinder 12, and the second driving member 122 is fixedly connected to the second piston 121;

[0056] The second oil outlet passage 16 is in communication with the second oil cylinder 12, and the second oil outlet passage 16 is connected to a second disc brake unit (not shown in the figure), and the second disc brake unit is controlled by the pressure of the second oil cylinder 12;

[0057] Along the axial direction of the second oil cylinder 12, the second connecting oil passage 14 and the second oil outlet oil passage 16 are staggered.

[0058] The first oil tank 21 and the second oil tank 22 are arranged horizontally side by side;

[0059] Reference Figure 1-Figure 2 When in use, the horizontal positions of the first oil tank 21 and the second oil tank 22 are higher than the first oil cylinder 11 and the second oil cylinder 12.

[0060] By arranging the first oil cylinder 11 and the second oil cylinder 12 independently of each other on the same housing, the two oil pumping chambers are arranged separately, so that the structures for controlling the first disc brake unit and the second disc brake unit can be integrated into one brake oil pump conversion device product; if there is a problem with the first oil cylinder 11 or the second oil cylinder 12, the other oil cylinder can continue to work, thereby improving the reliability of the entire brake oil pump conversion device system;

[0061] The working principles of the following components are the same: the first oil tank 21 and the second oil tank 22, the first oil cylinder 11 and the second oil cylinder 12, the first connecting oil path 13 and the second connecting oil path 14, the first oil outlet oil path 15 and the second oil outlet oil path 16, the first piston 111 and the second piston 121, the first driving member 112 and the second driving member 122, the first disc brake unit and the second disc brake unit;

[0062] Take the first oil tank 21, the first oil cylinder 11, the first connecting oil circuit 13, the first oil outlet oil circuit 15, the first piston 111, the first driving member 112 and the first disc brake unit as an example: the existing design is that the first oil tank 21 is arranged in parallel on one side of the first oil cylinder 11, and the first oil tank 21 is connected to the first oil cylinder 11 through the horizontally arranged first connecting oil circuit 13. When the first driving member 112 is released to return the oil, the liquid in the first oil tank 21 needs to overcome the resistance and gravity of the inner wall of the first connecting oil circuit 13. This requires that when pulling the first driving member 112, the rider applies a greater braking force to the oil pump system to ensure that when returning the oil, there is enough pressure in the oil pump system to overcome the resistance and gravity of the inner wall of the first connecting oil circuit 13.

[0063] In this embodiment, the first oil tank 21 and the second oil tank 22 are arranged horizontally side by side, and the horizontal positions of the first oil tank 21 and the second oil tank 22 are higher than the first oil cylinder 11 and the second oil cylinder 12;

[0064] Similarly, take the first oil tank 21, the first oil cylinder 11, the first connecting oil path 13, the first oil outlet oil path 15, the first piston 111, the first driving member 112 and the first disc brake unit as an example: when the first driving member 112 is released to return the oil, part of the gravity can be used to assist the liquid in the first oil tank 21 to overcome the resistance of the inner wall of the first connecting oil path 13. When the first driving member 112 is pulled, the rider applies a smaller braking force to the oil pump system, and the oil pump system does not have enough pressure to overcome the resistance of the inner wall of the first connecting oil path 13 and part of the gravity.

[0065] Therefore, the horizontal positions of the first oil tank 21 and the second oil tank 22 are higher than the first oil cylinder 11 and the second oil cylinder 12. During use, the oil in the first oil tank 21 and the second oil tank 22 can flow smoothly into the first oil cylinder 11 and the second oil cylinder 12 under the action of gravity, thereby improving the efficiency of oil flow, thereby enhancing the braking effect and making the braking response more timely.

[0066] Reference Figure 3 , further, the first connecting oil passage 13 vertically connects the first oil tank 21 and the first oil cylinder 11;

[0067] The second connecting oil passage 14 vertically connects the second oil tank 22 and the second oil cylinder 12 .

[0068] First, the vertical arrangement of the first connecting oil passage 13 and the second connecting oil passage 14 further utilizes gravity to help the liquid flow. At this time, all gravity in the brake oil pump conversion device system is used to overcome the resistance of the inner wall of the first connecting oil passage 13, assisting the liquid in the first oil tank 21 to flow to the first oil cylinder 11, and overcome the resistance of the inner wall of the second connecting oil passage 14, assisting the liquid in the second oil tank 22 to flow to the second oil cylinder 12;

[0069] Secondly, after the brake pads and discs in the first disc brake unit and the second disc brake unit are worn, the first oil tank 21 and the second oil tank 22 can be replenished to the caliper to the maximum extent, thereby improving the life and stability of the caliper in the first disc brake unit and the second disc brake unit, further improving the braking effect, and reducing the energy required for braking of the brake oil pump conversion device system.

[0070] Finally, taking the first oil tank 21 as an example, due to the large vertical height difference from the first oil tank 21 to the first disc brake unit, and because air tends to rise, when the brake oil pump conversion device is filled with oil, the air in the first disc brake unit and the first oil cylinder 11 is promoted to be discharged, so as to prevent the air from staying in the first disc brake unit and the brake oil tank system and affecting the braking effect.

[0071] Furthermore, the first oil cylinder 11 and the second oil cylinder 12 are arranged horizontally side by side. On the one hand, it helps to balance the load of the brake oil pump conversion device and reduce the wear of the housing 1-3 due to uneven load. On the other hand, it can more effectively utilize space and facilitate hiding the brake oil pump conversion device.

[0072] Further, there are two first connecting oil passages 13 and they are located on the same axial plane of the first oil tank 21 ; there are two second connecting oil passages 14 and they are located on the same axial plane of the second oil tank 22 .

[0073] There are two first connecting oil circuits 13 and second connecting oil circuits 14, which can provide more liquid to flow from the first oil cylinder 11 to / out of the first oil tank 21 and from the second oil cylinder 12 to / out of the second oil tank 22, thereby improving the braking response speed of the brake oil pump conversion device system, which is particularly suitable for long-term braking downhill.

[0074] Furthermore, a hatch cover 4 is included. The housing 1-3 includes a housing A surface 31. The housing A surface 31 is provided with an oil tank opening 311. The first oil tank 21 and the second oil tank 22 are located in the oil tank opening 311. The hatch cover 4 is detachably connected to the housing A surface 31, and the hatch cover 4 is used to close the oil tank opening 311. Therefore, by opening a hatch cover 4, the working conditions of the first oil tank 21 and the second oil tank 22 can be observed at the same time, which is convenient for repairing the first oil tank 21 and the second oil tank 22. From the appearance point of view, the provision of a hatch cover 4 can make the appearance of the brake oil pump conversion device more neat and beautiful.

[0083] The first oil filling hole 351 is connected to the first oil tank 21;

[0084] The second oil filling hole 352 is communicated with the second oil tank 22 .

[0085] The first oil filling hole 351 and the second oil filling hole 352 are arranged on the same surface, which is convenient for filling the first oil tank 21 and the second oil tank 22 with oil, and the shell E surface 35 is not parallel to the shell A surface 31, which helps to observe the first oil tank 21 and the second oil tank 22 while filling the oil.

[0086] More specifically, a connecting ear 323 is provided on the shell B surface 32, which is used to fix the brake oil pump conversion device on the cycling vehicle; the connecting ear 323 is located above the horizontal connecting line of the axis of the first oil outlet pipe interface 321 and the second oil outlet pipe interface 322, so that it is convenient to insert an installation tool from between the first oil outlet pipe interface 321 and the second oil outlet pipe interface 322 to install the connecting ear 323.

[0088] A cycling vehicle comprises a handlebar, wherein a mounting groove is provided at the bottom of the handlebar, and the brake oil pump conversion device as described above is mounted on the mounting groove.

[0089] Since the riding vehicle has the brake oil pump conversion device as described above, the handlebar also has the beneficial effects of the brake oil pump conversion device as described above;

[0090] Specifically, the brake oil pump conversion device can be completely embedded in the installation groove, hiding the brake oil pump conversion device from the appearance of the handlebar, which can reduce the wind resistance generated by the brake oil pump conversion device structure on the one hand, and improve the ornamental value of the handlebar on the other hand.
