[0031] See Figure 1 and Figure 2 This illustration shows a schematic diagram of a brake operating device according to an embodiment of this application. The brake operating device is used to mount on the handlebars of a bicycle. The brake operating device includes a connector 100, a handbrake mechanism 200, and a locking assembly 300. The connector 100 is provided with a first mounting hole 110. Specifically, the connector 100 is used to connect the brake operating device to the handlebars of the bicycle. It should be noted that the bicycle in this application includes, but is not limited to, human-powered bicycles or electric bicycles.

[0032] The handbrake mechanism 200 includes a first handle 210 and a rotating shaft 220. The first handle 210 is provided with a connecting part 211 and a second mounting hole 212. The first mounting hole 110 and the second mounting hole 212 are coaxially arranged. The rotating shaft 220 passes through the second mounting hole 212 and is mounted in the first mounting hole 110, so that the connecting part 211 and the first handle 210 can rotate around the rotating shaft 220.

[0033] The locking component 300 is installed on the connecting part 211. The locking component 300 is used to lock the first handle 210 to restrict the first handle 210 from rotating around the pivot 220, or to release the first handle 210 so that the first handle 210 can rotate around the pivot 220.

[0034] In one embodiment, the connector 100 has a mounting groove on the side near the first handle 210, and the first mounting hole 110 communicates with the mounting groove. When the first handle 210 is not in its original position, the connector 211 is placed in the mounting groove, thereby enhancing the reliability and stability of the first handle 210.

[0035] The brake operating device described in this embodiment of the application includes a connector 100 for mounting the brake operating device to a bicycle. A rotating shaft 220 is mounted in the first mounting hole 110 of the connector 100 and passes through the second mounting hole 212 of the first handlebar 210, allowing the first handlebar 210 to rotate around the rotating shaft 220. Braking can be achieved by squeezing and rotating the first handlebar 210. The connecting portion 211 of the first handlebar 210 is also equipped with a locking component 300. The locking component 300 is used to lock or release the rotational relationship between the first handlebar 210 and the connector 100. That is, the locking component 300 can restrict the relative rotation of the first handlebar 210 and the connector 100, or allow the first handlebar 210 to operate normally after the restriction is released.

[0036] The brake operating device described in this application embodiment rotatably connects the first handle 210 to the connector 100, and installs a locking component 300 on the first handle 210. The locking component 300 is used to lock or release the rotation of the first handle 210. In the event of an oncoming emergency collision, the first handle 210 is locked to minimize the risk of fingers being pinched by external force, thus reducing safety hazards during the use of the brake operating device. Moreover, during normal driving, unlocking the first handle 210 allows for normal braking without restricting the freedom of hand movement, providing convenient brake operation and offering advantages such as high safety and ease of use.

[0037] Combination Figures 3 to 5 This diagram illustrates the internal structure of a brake operating device according to one embodiment of this application. In some embodiments, the locking assembly 300 includes a limiting member 310 and a second handle 320. The connecting portion 211 has a first mounting cavity 213, which communicates with a first mounting hole 110. The limiting member 310 is movably disposed in the first mounting cavity 213 and is detachably connected to the rotating shaft 220. The second handle 320 is driven to connect the limiting member 310 to the rotating shaft 220 to lock the rotation of the first handle 210, or to drive the limiting member 310 to separate from the rotating shaft 220 to release the rotation of the first handle 210. Specifically, the limiting member 310 moves back and forth in the same direction in the first mounting cavity 213. The limiting member 310 is in a locked position when connected to the rotating shaft 220 and in a released position when separated from the rotating shaft 220. The second handle 320 drives the limiting member 310 to move back and forth between the locked position and the released position.

[0038] This embodiment utilizes a drive-coupling structure between the limiting member 310 and the second handle 320. When the second handle 320 is engaged, the limiting member 310 moves from the locked position to the released position, thereby unlocking the first handle 210. In other words, without changing existing braking habits, users only need to place their fingers on both the first handle 210 and the second handle 320 simultaneously to engage the second handle 320, driving the limiting member 310 to separate from the pivot 220 and unlocking it. This allows for operation of the first handle 210 to complete the braking operation. The overall action is convenient and fluid, ensuring the reliability of the second handle 320's locking while maintaining the convenience and fluidity of the first handle 210's braking operation, effectively improving the user experience and operational safety.

[0039] In one exemplary embodiment, such as Figure 2 As shown, the second handle 320 is located at the front end of the first handle 210, and the length of the second handle 320 is less than the length of the first handle 210. Specifically, the second handle 320 is usually designed to allow one or two fingers to operate it, so that after one or two fingers operate the second handle 320 to unlock it, the remaining fingers can continuously operate the first handle 210 to brake, thus improving the convenience of operation.

[0040] In an optional embodiment, the first handlebar 210 is further provided with a protrusion 230, which is located on the side of the first handlebar 210 away from the connector 100, that is, on the side of the bicycle's forward direction. The protrusion 230 is provided with a second mounting cavity 231, which communicates with the first mounting cavity 213. The second handlebar 320 is movably inserted into the second mounting cavity 231, so that the second handlebar 320 extends out from the side of the protrusion 230.

[0041] Furthermore, the protrusion 230 is located on the side of the first handlebar 210 facing the direction of travel of the bicycle, and the height of the protrusion 230 in the direction of travel of the bicycle exceeds the height of the second handlebar 320 in the direction of travel of the bicycle.

[0042] In this embodiment, a protrusion 230 is provided at the front end of the first handle 210, and the second mounting cavity 231 of the protrusion 230 provides mounting space for the second handle 320. Moreover, the protrusion 230 is designed to protrude from the second handle 320, so that when the brake operation device is involved in a frontal collision, the protrusion 230 contacts the colliding object first, thereby reducing the collision point from occurring on the second handle 320 and improving the safety of the brake operation device.

[0043] In an optional embodiment, such as Figure 4 and Figure 5As shown, the locking assembly 300 also includes a gear 330, which is rotatably mounted in the second mounting cavity 231. The limiting member 310 is provided with a rack 312, and the gear 330 is meshed with the rack 312. The second handle 320 is connected to the gear 330.

[0044] In this embodiment, a gear 330 meshing with the rack 312 of the limiting member 310 is provided in the second mounting cavity 231, and the second handlebar 320 is connected to the gear 330. The rider pulls the second handlebar 320, which drives the gear 330 to rotate, thereby causing the limiting member 310 to separate from the rotating shaft 220, thus unlocking the first handlebar 210. This embodiment utilizes the smoothness and precision of the gear 330's meshing transmission to achieve efficient transmission of the driving force of the second handlebar 320 to the limiting member 310. This improves the accuracy and reliability of the connection or separation action between the limiting member 310 and the rotating shaft 220, and makes the unlocking operation more even and effortless, further ensuring the stability of the locked state and the smoothness of the unlocking operation, thus optimizing the overall user experience.

[0045] In an exemplary embodiment, the end of the second handle 320 is detachably connected to the gear 330. The connection method can be a threaded connection or a plug-in fixation, which facilitates the assembly of the locking component 300.

[0046] In an optional embodiment, such as Figure 4 and Figure 5 As shown, the locking assembly 300 also includes a reset member 340, which is disposed in the second mounting cavity 231 and connected to the second handle 320. The reset member 340 is used to drive the second handle 320 to reset from the release position to the locking position.

[0047] In an optional embodiment, such as Figure 4 and Figure 5 As shown, the rotating shaft 220 has a notch 221, and the limiting member 310 has a pin 311. The second handle 320 drives the pin 311 to be detachably inserted into the notch 221. When the pin 311 is inserted into the notch 221, the first handle 210 restricts rotation, or when the pin 311 is separated from the notch 221, the first handle 210 releases rotation.

[0048] In this embodiment, the notch 221 of the rotating shaft 220 and the pin 311 of the limiting member 310 are detachably plugged and pulled together to form a simple and compact mechanical interlocking structure. The so-called interlocking structure means that after the pin 311 is inserted into the notch 221, since the rotating shaft 220 and the connecting member 100 are regarded as a fixed whole, and the limiting member 310 and the first handle 210 are regarded as a fixed whole, the rotation relationship of these two main bodies is locked when the pin 311 is inserted into the notch 221, thereby realizing the rapid locking and releasing of the rotation of the first handle 210. The precise fit between the pin 311 and the notch 221 ensures the stability of the locked state and improves the reliability of the locking component 300 and the smoothness of unlocking.

[0049] In an optional embodiment, in order to avoid affecting the normal rotation of the first handle 210, the axial length of the notch 221 is less than the thickness of the connecting part 211, so as to avoid affecting the rotational fit between the rotating shaft 220 and the connecting part 211 due to the notch 221, thereby improving the reliability of the brake operating device.

[0050] In an optional embodiment, such as Figure 5 As shown, the rotating shaft 220 is provided with a positioning part 222, and the hole wall of the first mounting hole 110 is provided with a positioning groove 111, and the positioning part 222 is engaged in the positioning groove 111.

[0051] In this embodiment, a positioning part 222 is provided on the rotating shaft 220, and a positioning groove 111 that mates with the positioning part 222 is provided on the first mounting hole 110. When the rotating shaft 220 is installed into the first mounting hole 110, the positioning part 222 and the positioning groove 111 cooperate to restrict the rotation of the rotating shaft 220. That is, the position of the rotating shaft 220 relative to the connecting member 100 is fixed, which facilitates the assembly of the rotating shaft 220. In addition, since the position of the rotating shaft 220 is fixed, the position of the notch 221 is also fixed, so that the position of the notch 221 matches the limiting member 310 after the rotating shaft 220 is installed. This has the advantages of convenient assembly and structural stability.

[0052] In an optional embodiment, such as Figure 3 As shown, the connector 100 is provided with a wire passage 120, which is used for the brake cable to pass through and connect to the connector 211. By passing the brake cable through the wire passage 120 and connecting it to the connector 211 of the first handle 210, when the first handle 210 is pulled, the brake cable is moved, thereby completing the braking operation.

[0053] In an optional embodiment, such as Figure 2 and Figure 3As shown, the connector 100 has a first arc-shaped portion 130 and a second arc-shaped portion 140. The first arc-shaped portion 130 has a first connecting hole 131, and the second arc-shaped portion 140 has a second connecting hole 141. The first connecting hole 131 and the second connecting hole 141 are used to install a first fastener so that the first arc-shaped portion 130 and the second arc-shaped portion 140 are connected to form a ring.

[0054] The brake operating device in this embodiment needs to be installed on the handlebars of a bicycle. Typically, bicycle handlebars have a circular cross-section. A ring structure is formed by the cooperation of the first arc-shaped portion 130 and the second arc-shaped portion 140, allowing the handlebars to fit into the ring structure. The first arc-shaped portion 130 and the second arc-shaped portion 140 are adapted to the arc-shaped design of the bicycle handlebars, resulting in a better fit. Then, the first connecting hole and the second connecting hole are connected by a first fastener, thereby ensuring the firmness and stability of the installed brake operating device, while also enabling quick installation and removal, optimizing the user and maintenance experience.

[0055] On the other hand, this application also provides a bicycle, including handlebars and a brake operating device as described in any of the above embodiments, the brake operating device being mounted on the handlebars and used by the rider to operate the brakes.

[0056] The bicycle described in this embodiment has a brake operating device installed on the handlebars. This device rotatably connects a first handlebar 210 to a connector 100, and a locking component 300 is installed on the first handlebar 210. The locking component 300 is used to lock or release the rotation of the first handlebar 210. In the event of an oncoming emergency collision, the first handlebar 210 is locked to minimize the risk of fingers being pinched by external force, reducing safety hazards during the use of the brake operating device. Furthermore, during normal riding, unlocking the first handlebar 210 allows for normal braking without restricting hand freedom of movement, providing convenient brake operation and offering advantages of high safety and ease of use.

[0057] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0058] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
