[0027] Reference Figure 1 , Figure 2 A handlebar matched with an oil cylinder, wherein a mounting groove 11 for mounting a brake oil cylinder is provided at the bottom of the handlebar.

[0028] In bicycle competitions, wind resistance is the biggest source of resistance in bicycle riding. Reducing wind resistance can enable riders to achieve higher riding speeds under the same power output, especially for long-time competitions, reducing wind resistance helps to save riders' physical strength. As a kind of bicycle automatic device, the brake oil pump can provide strong braking force through the hydraulic system. The brake oil pump has the advantages of stable braking effect, long service life and fast braking response, and is often used in competition bicycles. The existing matching relationship between the brake oil cylinder and the handlebar is generally that the brake oil cylinder is installed at the front end or top of the handlebar. In order to solve the wind resistance problem of the brake oil cylinder, the means adopted is to improve the outer contour of the brake oil cylinder so that the windward surface of the brake oil cylinder has smooth lines, such as the bicycle hydraulic disc brake device disclosed in Chinese patent CN206394795U.

[0029] The design of the mounting groove 11 of the present application allows for embedded installation of the brake cylinder; compared with making a groove at the top of the handlebar and installing the brake cylinder therein, making a groove at the bottom of the handlebar can prevent rainwater from entering the mounting groove 11 and corroding the brake oil pump in the mounting groove 11; compared with making a groove at the front end of the handlebar and installing the brake cylinder therein, making a groove at the bottom of the handlebar can reduce the increase in wind resistance of the handlebar due to the non-streamlined design of the front end of the brake cylinder and the increase in the windward area of ​​the brake cylinder; therefore, setting the mounting groove 11 at the bottom of the handlebar achieves dynamic optimization of the handlebar, reduces the wind resistance of the handlebar, and reduces the influence of the brake cylinder installed on the handlebar on the riding speed.

[0030] Furthermore, the mounting groove 11 is provided in the middle portion 1 of the handlebar. In this case, the mounting groove 11 can be used to install a brake oil pump with integrated bilateral braking, so that the distance from the oil chamber of the brake oil pump installed in the mounting groove 11 to the left brake handle is consistent with the distance to the right brake handle, effectively transmitting the braking force; and the mounting groove 11 being provided in the middle helps to maintain the balance of the handlebar, so that the mass distribution of the brake oil pump is more uniform.

[0031] Furthermore, the handlebar also includes a vertical tube mounting groove 13, which is equivalent to the integrated setting of the handlebar and the handlebar of a traditional bicycle; in this way, the handlebar is directly mounted on the vertical tube, and the vertical tube can directly provide support to the handlebar, thereby enhancing the stability of the handlebar structure; on the other hand, it helps to maintain the relative position relationship between the vertical tube and the brake cylinder, thereby reducing the position of the brake cylinder caused by the looseness of the handlebar during riding.

[0032] Specifically, the mounting groove 11 is communicated with the vertical tube mounting groove 13; after the brake cylinder is installed in the mounting groove, the oil circuit wiring connecting the brake cylinder and the disc brake is routed along the vertical tube to the brake disc, and the mounting groove 11 is communicated with the vertical tube mounting groove 13, so that the oil circuit wiring can smoothly extend from the mounting groove 11 and be attached to the vertical tube after passing through the vertical tube mounting groove 13. On the one hand, this arrangement can play a role in hiding the oil circuit wiring and reduce brake failure caused by damage to the oil circuit wiring; on the other hand, it can improve the neatness of the oil circuit routing, and its application on bicycles can improve the overall aesthetics of the bicycle.

[0033] Furthermore, the mounting groove 11 is a "T"-shaped mounting groove, and the "T"-shaped arrangement can provide lateral and longitudinal support for the installation of the brake oil pump, thereby improving the stability of the installation of the brake oil pump;

[0034] Furthermore, a mounting member 111 for fixing an auxiliary brake cylinder is provided on the inner wall of the mounting groove 11. The setting of the mounting member 111 can further improve the stability of the brake oil pump installation, and the mounting member 111 can be designed to adapt to various models of brake cylinders, thereby increasing the versatility and compatibility of the mounting groove.

[0035] Furthermore, the handlebar includes an arc-shaped windward surface 12 disposed at the front end of the handlebar, and the arc-shaped windward surface 12 is disposed adjacent to the mounting groove 11. The arc-shaped windward surface 12 can more effectively guide the airflow, reduce air resistance, and improve the aerodynamic performance of the bicycle, especially when riding at high speed, and can improve the controllability of the handlebar during driving or turning.

[0036] Furthermore, the handlebar further comprises a left connecting portion 2, a left handle 3, a right connecting portion 4 and a right handle 5;

[0037] The left connecting portion 2 and the left handle 3, the right connecting portion 4 and the right handle 5 are symmetrically arranged with the middle portion 1 as the center;

[0038] The left connecting portion 2 has a left wiring groove 21 at its bottom, and the right connecting portion 4 has a right wiring groove 41 at its bottom.

[0039] The brake oil pump is connected to the brake handle with a brake line. The existing handlebar structure is that the brake line is wrapped around the handlebar with tape, and the brake line protrudes from the surface of the handlebar; the left wiring groove 21 and the right wiring groove 41 are provided to accommodate the brake line. On the one hand, the brake line can be hidden from the appearance of the handlebar, making the handlebar area look more tidy and beautiful; on the other hand, since the brake oil cylinder is installed at the bottom of the handlebar, this also means that the brake line needs to be routed from the bottom of the handlebar. If the brake line protrudes from the handlebar, it will also increase the windward area of ​​the handlebar and increase the wind resistance of the handlebar. The brake handle line is accommodated in the left wiring groove 21 and the right wiring groove 41. When riding, the wind is diverted by the curved windward surface 12 and does not directly contact the brake line at the bottom of the handlebar, which can reduce the wind resistance.

[0040] Since a mounting groove 11 is provided at the bottom of the middle portion 1, the middle portion 1 has a stress concentration problem. For example, the strength of the middle portion 1 of the handlebar is consistent with the left connecting portion 2, the left handle 3, the right connecting portion 4 and the right handle 5. The handlebar is prone to breakage from the middle portion 1, affecting the safety of the rider. Specifically, the structural strength of the middle portion 1 of the handlebar is greater than the structural strength of the left connecting portion 2, the left handle 3, the right connecting portion 4 and the right handle 5, thereby improving the safety of the handlebar.

[0041] Specifically, the depth of the mounting groove 11 is greater than the depth of the left wiring groove 21 and the right wiring groove 41. The greater depth of the mounting groove 11 means that it can accommodate a brake oil pump with a larger oil storage capacity. The left wiring groove 21 and the right wiring groove 41 are relatively shallow, which makes it easy to place the brake cable against the inner walls of the left wiring groove 21 and the right wiring groove 41 during wiring, and the brake cable can be firmly fixed by tying tape on the handlebar.

[0042] Specifically, the width of the left wiring groove 21 decreases from the middle part 1 to the left handle 3, and the width of the right wiring groove 41 decreases from the middle part 1 to the right handle 5; this is because the connection position between the brake cable and the brake cylinder is fixed, and the width of the left wiring groove 21 and the right wiring groove 41 is large near the middle part 1 to adapt to the installation of brake cylinders of different specifications. The width of the left wiring groove 21 and the right wiring groove 41 decreases because the brake cable itself has a certain flexibility. The left wiring groove 21 and the right wiring groove 41 gradually become narrower, and the narrowed part can limit the movement of the brake cable, which helps to fix the brake cable.

[0043] The above is a specific description of the preferred implementation of the utility model, but the invention of the utility model is not limited to the described embodiments. Technical personnel familiar with the field can also make various equivalent deformations or substitutions without violating the spirit of the utility model. These equivalent deformations or substitutions are all included in the scope defined by the claims of this application.
