technical field

本发明涉及自行车内变速器技术领域，尤其涉及一种内变速器中换档控制器的控制结构、内变速器及自行车。The invention relates to the technical field of bicycle internal derailleurs, in particular to a control structure of a shift controller in the internal derailleur, the internal derailleur and a bicycle.

Background technique

自行车，又称脚踏车或单车，通常是二轮的小型陆上车辆。人骑上车后，以脚踩踏板为动力，是绿色环保的交通工具。现代社会中，自行车已成为世界各国特别是发达国家居民喜爱的交通、健身工具。同时，世界自行车行业的重心也从传统的代步型交通工具向运动型、山地型、休闲型转变，在美、欧、日等发达国家，自行车更是成为了一种普遍的运动、健身、休闲和娱乐性产品。并且随着技术的不断发展，自行车内变速器的出现，也越来越方便了用户对自行车档位的调节。A bicycle, also known as a bicycle or bicycle, is usually a small land vehicle with two wheels. After a person rides on the car, it is powered by pedals, which is a green and environmentally friendly means of transportation. In modern society, bicycles have become a favorite transportation and fitness tool for residents of countries all over the world, especially developed countries. At the same time, the focus of the world's bicycle industry has shifted from traditional means of transportation to sports, mountain and leisure. In developed countries such as the United States, Europe, and Japan, bicycles have become a common sport, fitness, and leisure. and entertainment products. And along with the continuous development of technology, the appearance of the transmission in the bicycle has also made it more and more convenient for the user to adjust the gear position of the bicycle.

现有技术的内变速器中大致分为轮毂轴、输入机构、输出机构、变速机构以及换档控制机构等部件。其中，输入机构用以与自行车后轮的飞轮连接，从而当内变速器安装于自行车上时，输入机构能通过飞轮的带动下发生旋转。输出机构通常为后轮毂壳，从而当内变速器安装于自行车上时，输出机构的转动能同步带动后轮转动，实现自行车的行进。变速机构设置于输入机构与输出机构之间，为输入机构与输出机构之间的传动部件，用以将输入机构的旋转动力传递至输出机构，从而带动输出机构转动。其中，变速机构中设置有多个动力传递路径，换档控制机构用以对变速机构进行控制，从而用户可通过操控换档控制机构对变速机构进行控制，选择变速机构中的一个动力传递路径将输入机构的旋转动力传递至输出机构中。The internal transmission of the prior art is roughly divided into components such as a hub shaft, an input mechanism, an output mechanism, a speed change mechanism, and a shift control mechanism. Wherein, the input mechanism is used to connect with the flywheel of the rear wheel of the bicycle, so that when the internal derailleur is installed on the bicycle, the input mechanism can be driven by the flywheel to rotate. The output mechanism is usually the rear wheel hub shell, so that when the internal transmission is installed on the bicycle, the rotation of the output mechanism can synchronously drive the rear wheel to rotate, so as to realize the advancement of the bicycle. The speed change mechanism is arranged between the input mechanism and the output mechanism, and is a transmission component between the input mechanism and the output mechanism, and is used to transmit the rotational power of the input mechanism to the output mechanism, thereby driving the output mechanism to rotate. Wherein, the speed change mechanism is provided with multiple power transmission paths, and the shift control mechanism is used to control the speed change mechanism, so that the user can control the speed change mechanism by manipulating the shift control mechanism, and selecting one of the power transmission paths in the speed change mechanism will The rotational power of the input mechanism is transmitted to the output mechanism.

变速机构包括多组行星轮系，换档控制机构通过控制不同行星轮系中的太阳轮是否转动，从而实现对动力传递路径的选择。换档控制机构包括换档控制器及控制组件，换档控制器用以控制太阳轮控制棘爪，控制组件包括保持板及换档套筒。具体的，太阳轮控制棘爪设置于轮毂轴上，且太阳轮控制棘爪沿轮毂轴的轴向依次设置有多个，每个太阳轮控制棘爪对应一个太阳轮设置，从而通过不同的太阳轮控制棘爪可以控制不同的太阳轮。换档控制器用以控制太阳轮控制棘爪的下压，且换档控制器上对应每个太阳轮控制棘爪均设置有控制臂，从而通过将换档控制器转动至不同角度能实现下压不同的太阳轮棘爪，实现对动力传递路径的选择。保持板固定在轮毂轴上，换档套筒穿过保持板与棘爪控制件连接。用户在换档操作时，调节位于自行车车把上的换档器，通过换档器带动换档套筒转动，然后换档套筒带动换档控制器转动，再由换档控制器下压太阳轮控制棘爪，让太阳轮控制棘爪与太阳轮分离。通过换档套筒将换档控制器转动至不同角度，实现对不同的太阳轮棘爪的下压，进而实现对动力传递路径的选择。即通过将棘爪控制件转动到不同角度，从而能实现将变速机构调节为不同速比档位进行输出。The transmission mechanism includes multiple sets of planetary gear trains, and the shift control mechanism realizes the selection of the power transmission path by controlling whether the sun gears in different planetary gear trains rotate. The shift control mechanism includes a shift controller and a control assembly, the shift controller is used to control the sun gear control pawl, and the control assembly includes a retaining plate and a shift sleeve. Specifically, the sun gear control pawl is arranged on the hub shaft, and several sun gear control pawls are arranged in sequence along the axial direction of the hub shaft. Each sun gear control pawl corresponds to a sun gear setting, so that through different The wheel control pawl can control different sun wheels. The gear shift controller is used to control the pressing down of the sun gear control pawl, and the gear shift controller is provided with a control arm corresponding to each sun gear control pawl, so that the down pressure can be realized by turning the gear shift controller to different angles Different sun gear pawls realize the selection of power transmission path. The retaining plate is fixed on the hub shaft, and the shift sleeve passes through the retaining plate and is connected with the pawl control member. When shifting gears, the user adjusts the shifter located on the handlebar of the bicycle, the shifter drives the shift sleeve to rotate, and then the shift sleeve drives the shift controller to rotate, and then the shift controller presses down on the sun. The wheel control pawl allows the sun gear control pawl to separate from the sun gear. The shift controller is rotated to different angles through the shift sleeve to realize the pressing down of different sun gear pawls, thereby realizing the selection of the power transmission path. That is, by turning the pawl control member to different angles, the speed change mechanism can be adjusted to different speed ratio gears for output.

然而，现有技术中由于受到保持板的限制，换档套筒能带动换档控制器的角度受限，导致档位可布置的转动范围受限，增加了对不同速比档位调节的控制难度。特别是当变速机构中档位较多时，档位集中布置在较小的转动范围内，相邻两个档位之间间隔角度极小，容易导致在调节过程中出现跳档或调档不成功的现象，同时也极大的限制了内变速器中档位设置的数量。However, in the prior art, due to the restriction of the retaining plate, the angle at which the shift sleeve can drive the shift controller is limited, resulting in a limited rotation range for the gear positions to be arranged, which increases the control over the adjustment of gear positions with different speed ratios difficulty. Especially when there are many gears in the transmission mechanism, the gears are concentrated in a small rotation range, and the interval angle between two adjacent gears is extremely small, which will easily lead to gear skipping or unsuccessful gear adjustment during the adjustment process. At the same time, it also greatly limits the number of gear settings in the internal transmission.

所述限位件10或所述控制件20上开设有沿周向延伸的滑槽50，所述控制件20或所述限位件10至少部分位于所述滑槽50中，所述限位件10用以对所述控制件20转动时进行导向限位。即所述限位件10上开设有沿周向延伸的所述滑槽50，或所述控制件20上开设有沿周向延伸的所述滑槽50。相对应的，当所述滑槽50开设于所述限位件10上时，所述控制件20至少部分位于所述滑槽50中；当所述滑槽50开设于所述控制件20上时，所述限位件10至少部分位于所述滑槽50中。从而当所述控制件20转动时，能通过所述滑槽50的槽壁与所述控制件20中位于所述滑槽50中的部分相互抵接配合，实现对所述控制件20的导向限位，确保所述控制件20能沿所需方向转动；或通过所述滑槽50的槽壁与所述限位件10中位于所述滑槽50中的部分相互抵接配合，实现对所述控制件20的导向限位，确保所述控制件20能沿所需方向转动。其中，周向延伸是以所述轮毂轴30的周向作为参考，从而确保所述控制件20能以所述轮毂轴30为中心进行转动。The limiter 10 or the control member 20 is provided with a sliding groove 50 extending in the circumferential direction, the control member 20 or the limiter 10 is at least partly located in the slide groove 50, the limiter The member 10 is used to guide and limit the control member 20 when it rotates. That is, the limiting member 10 is provided with the sliding groove 50 extending in the circumferential direction, or the control member 20 is provided with the sliding groove 50 extending in the circumferential direction. Correspondingly, when the chute 50 is opened on the limiting member 10, the control member 20 is at least partially located in the chute 50; when the chute 50 is opened on the control member 20 , the limiting member 10 is at least partially located in the slide groove 50 . Therefore, when the control member 20 rotates, the groove wall of the chute 50 and the part of the control member 20 located in the chute 50 can abut and cooperate with each other, so as to realize the guidance of the control member 20 limit, to ensure that the control member 20 can rotate in the required direction; or through the groove wall of the chute 50 and the part of the limiter 10 that is located in the chute 50 to abut and cooperate with each other, to achieve alignment The guide limit of the control member 20 ensures that the control member 20 can rotate in a desired direction. Wherein, the circumferential extension takes the circumferential direction of the hub axle 30 as a reference, so as to ensure that the control member 20 can rotate around the hub axle 30 .

所述滑槽50沿周向延伸的角度不小于(大于等于)180°，且所述控制件20相对所述限位件10的可转动角度不小于(大于等于)180°。其中，所述滑槽50沿周向延伸的角度不小于180°指的是：所述滑槽50两端所构成的圆心角α不小于180°，所述滑槽50所构成的圆弧为优弧。所述控制件20相对所述限位件10的可转动角度不小于180°指的是：所述控制器20位于所述滑槽50中的部分能在所述滑槽50中进行不小于180°的转动，即所述控制器20位于所述滑槽50中的部分在起点位置与终点位置所构成的圆心角不小于180°，从而确保所述控制器20能实现不小于180°的转动；当然，当所述滑槽50设置于所述控制器20上时，则是所述限位件10位于所述滑槽50中的部分能在所述滑槽50中进行不小于180°的转动，即所述限位件10位于所述滑槽50中的部分在起点位置与终点位置所构成的圆心角不小于180°。The circumferentially extending angle of the chute 50 is not less than (greater than or equal to) 180°, and the rotatable angle of the control member 20 relative to the limiting member 10 is not less than (greater than or equal to) 180°. Wherein, the angle extending along the circumferential direction of the chute 50 is not less than 180° means that the central angle α formed by the two ends of the chute 50 is not less than 180°, and the arc formed by the chute 50 is superior arc. The rotatable angle of the control member 20 relative to the limiting member 10 is not less than 180°, which means that the part of the controller 20 located in the chute 50 can be rotated in the chute 50 by not less than 180°. ° rotation, that is, the central angle formed by the part of the controller 20 located in the chute 50 at the start position and the end position is not less than 180°, so as to ensure that the controller 20 can achieve a rotation of not less than 180° Of course, when the chute 50 is arranged on the controller 20, the part of the limiting member 10 located in the chute 50 can be moved in the chute 50 by not less than 180° Rotation, that is, the central angle formed by the part of the limiting member 10 located in the slide groove 50 at the starting position and the ending position is not less than 180°.

需要说明的是，现有技术中由于受到保持板的限制，换档套筒仅能实现在小于180°的范围内进行转动，使得内变速器的档位调节均需集中布置在小于180°的范围内，档位可布置的转动范围受限。而本实施例中，将所述滑槽50设置成沿周向延伸的角度不小于180°，且所述控制件相对所述限位件的可转动角度不小于180°，从而让内变速器的档位调节可布置的转动范围更大，让内变速器中档位的布置可以更灵活，并且也能实现更多档位的布置。如当内变速器为10速(档)变速器时，采用现有技术中的结构，若将10档均匀布置，每个档位可占据的最大转动角度在15°左右。而采用本实施例提供的所述内变速器中换档控制器的控制结构100，则每个档位可占据的最大转动角度能布置在20°，甚至30°以上，从而可以让档位的布置更灵活。并且由于具有更大的转动角度，也能降低内变速器进行档位调节的控制难度，让其他控制部件的所需精度更低。可以理解的是，由于现有技术中换档套筒仅能在小于180°的范围内转动，受到内变速器中以及自行车上各部件精度的限制，导致内变速器的可布置的档位也受到限制，无法进一步的实现更多档位的布置。而本实施例提供的所述内变速器中换档控制器的控制结构100由于具有更大的转动角度，也使得内变速器中可设置的档位数量可以更多，突破了现有技术中的内变速器的档位数量的限制，可以更好的满足用户的多档位使用需求。It should be noted that in the prior art, due to the limitation of the retaining plate, the shift sleeve can only be rotated within a range of less than 180°, so that the gear adjustment of the internal transmission needs to be concentrated in a range of less than 180° Inside, the range of rotation in which the gears can be arranged is limited. In this embodiment, the chute 50 is set so that the angle extending in the circumferential direction is not less than 180°, and the rotatable angle of the control member relative to the limiting member is not less than 180°, so that the internal transmission The range of rotation that can be arranged for gear adjustment is larger, so that the arrangement of gears in the internal transmission can be more flexible, and the arrangement of more gears can also be realized. For example, when the internal transmission is a 10-speed (gear) transmission, the structure in the prior art is adopted. If the 10 gears are evenly arranged, the maximum rotation angle that each gear position can occupy is about 15°. However, if the control structure 100 of the shift controller in the internal transmission provided by this embodiment is adopted, the maximum rotation angle that each gear position can occupy can be arranged at 20°, or even more than 30°, so that the arrangement of the gear positions can more flexible. And because it has a larger rotation angle, it can also reduce the difficulty of controlling the gear adjustment of the internal transmission, so that the required precision of other control components is lower. It can be understood that, because the shift sleeve in the prior art can only rotate within a range of less than 180°, it is limited by the accuracy of the components in the internal transmission and on the bicycle, resulting in the limitation of the gears that can be arranged in the internal transmission. , it is impossible to further realize the arrangement of more stalls. However, the control structure 100 of the shift controller in the internal transmission provided in this embodiment has a larger rotation angle, which also enables more gears to be set in the internal transmission, which breaks through the internal transmission in the prior art. The limit on the number of gears of the transmission can better meet the needs of users for multi-gear use.
