Description

Technical Field

[0001] This utility model relates to the field of bicycle gear shifting control technology, specifically to a wireless electric gear shifting control device for bicycles that integrates multimodal interaction. Background Technology

[0002] The working principle of a bicycle's derailleur system is to adjust the gear ratio and thus change speed by changing the position of the chain on the front and rear sprockets (freewheel and front chainring). Specifically, the derailleur system consists of components such as derailleurs, chain, freewheel, and sprockets. When the rider operates the shift lever, the shift cable pulls the derailleur, causing the chain to move from one sprocket to another, thereby changing the gear ratio. For example, the front derailleur controls the position of the chain on the front chainring, while the rear derailleur controls the position of the chain on the freewheel.

[0003] The main function of the gear system is to adapt to different riding conditions, such as uphill, downhill, and flat roads. By selecting the appropriate gear combination, riders can reduce pedaling effort or increase speed. For example, when riding on a steep slope, a lower gear ratio (such as a small front chainring with a large cassette) can be selected to reduce pedaling effort; while on flat roads or downhill, a higher gear ratio (such as a large front chainring with a small cassette) can be selected to increase speed.

[0004] Modern bicycle shifting systems are generally divided into two types: manual and automatic. Manual shifting requires the rider to operate the shift levers manually, while automatic shifting uses built-in solenoid valves or hydraulic systems to automatically switch the chain. Traditional bicycle shifting systems have complex wiring, requiring cables to connect the handlebars and derailleurs, making internal wiring difficult and maintenance inconvenient. The wiring is also cumbersome and cannot support multi-mode interaction, making it difficult to meet the needs of modern intelligent riding.

[0005] Therefore, there is an urgent need to develop a highly integrated speed control device that supports multi-mode intelligent interaction in order to improve the ease of assembly and operation. Utility Model Content

[0054] This embodiment aims to address the complex wiring issues inherent in traditional bicycle gear systems. These systems require cables to connect the handlebars 100 control lever and derailleur, leading to difficult internal wiring within the frame, inconvenient maintenance, cumbersome cabling, and an inability to support multi-mode interaction, thus failing to meet the demands of modern intelligent cycling. Therefore, referring to… Figure 1-5As shown, this embodiment provides a wireless electric gear shifting control device for bicycles, including a touch screen component 3, a voice control component 4, and / or a gesture recognition component 5. It can input gear shifting commands in multiple modes, including touch, voice, and / or gesture, and supports multi-mode intelligent interaction. The command input function is integrated on the housing 1, and the housing 1 is detachably connected to the handlebar 100, making installation convenient. The command input component and the execution component are wirelessly connected, eliminating the need for wiring, resulting in high assembly convenience, high integration, and convenient operation.

[0055] Reference Figure 1 , 2 As shown in Figure 5, a wireless electric gear control device for bicycles includes: a housing 1, a power supply 2, a touch screen display component 3, a voice control component 4 and / or a gesture recognition component 5, a main control chip 6, and a wireless communication component 7. The housing 1 is hollow; the housing 1 can be detachably mounted on the handlebars 100 of a bicycle; the power supply 2 is located inside the housing 1.

[0056] The touch display component 3 is embedded in the surface of the housing 1 and is used to receive touch commands. The touch display component 3 is electrically connected to the power supply 2.

[0057] A voice control component 4 is disposed on the housing 1 and is used to receive user voice and recognize control commands. The voice control component 4 is electrically connected to the power supply 2. And / or a gesture recognition component 5 is disposed on the housing 1 and is used to receive user gestures and recognize control commands. The gesture recognition component 5 is electrically connected to the power supply 2.

[0058] The main control chip 6 is configured to integrate touch, voice and gesture signals and generate speed change commands. The main control chip 6 is electrically connected to the power supply 2, the touch display component 3, the voice control component 4 and the gesture recognition component 5 respectively.

[0059] The wireless communication component 7 is housed inside the housing 1 and is electrically connected to the power supply 2 and the main control chip 6.

[0060] Reference Figure 1 , 2As shown in Figure 5, the wireless communication component 7 can establish a bidirectional data connection with the electric derailleur 8; the electric derailleur 8 receives and executes speed change commands to perform chain shifting actions. Exemplarily, the housing 1 includes an upper housing 11 and a lower housing 12, which are fixed together by snap-fit ​​mechanisms. The hollow interior of the housing 1 forms an inner cavity 13 for mounting various components, and a main control circuit board 9 is fixed to the inner cavity 13 by bolts; the main control chip 6 and the wireless communication component 7 are integrated on the main control circuit board 9, which is located between the touch display component 3 and the power supply 2, and is electrically connected to each component's components. It should be added that the electric derailleur 8 can use existing electronic derailleurs. For example, the electric derailleur 8 can use existing Shimano electronic derailleurs, such as the R9150 electronic front derailleur and R9150 electronic rear derailleur, which have built-in rechargeable lithium-ion batteries, wireless communication modules, and drive motors. In this embodiment, the wireless communication component 7 can be configured as a Shimano-specific ANT+ / Bluetooth wireless transmitter to achieve bidirectional data connection with the electronic derailleur. For example, the wireless communication component 7 can be an integrated ANT+ compatible wireless communication chip. It should be noted that the feedback signals of the electric derailleur 8 can include gear position status, motor temperature, and battery level. For example, the R9150 rear derailleur transmits chain position data via wireless communication, and the main control chip 6 can link with the touch screen 31 to display the real-time gear position.

[0061] The main control chip 6 is configured to receive a combination of at least two control signals. When touch, voice control, and gesture control signals are input simultaneously, the touch signal from the touch display component 3 takes precedence over the voice signal from the voice control component 4 and the gesture signal from the gesture recognition component 5; the voice signal from the voice control component 4 takes precedence over the gesture signal from the gesture recognition component 5. For example, the main control chip 6 is connected to a priority encoder. The input end of the priority encoder is connected to the touch display component 3, the voice control component 4, and the gesture recognition component 5 via signal lines of different lengths. The signal line connecting to the touch display component 3 is shorter than the signal lines connecting to the voice control component 4 and the gesture recognition component 5, and the signal line connecting to the voice control component 4 is shorter than the signal line connecting to the gesture recognition component 5. Signal delay affects priority determination.

For example, the touch screen 31 employs self-capacitive touch technology, enabling multi-touch. The first touch area 312 (upshifting) and the second touch area 313 (downshifting) use a dynamic color block design: the default state is semi-transparent blue, turning into a bright orange when touched. In some embodiments, a vibration motor is integrated within the housing 1, electrically connected to the touch screen 31, providing micro-vibration feedback during touch. Optical micro-slits are set at the edge of the touch area, and the effective touch range is indicated by LED backlight; the third touch area 314 (reset) is designed as a circular icon, which triggers the reset command after a long press for 3 seconds, returning to the preset position.

The bottom of the housing 1 has a mounting hole 14, and the housing 1 is connected to the mounting hole 14 by a fastener 103, so that the housing 1 is fixed to the handlebar 100 of the bicycle. Specifically, the housing 1 is accommodated in the mounting groove 101, the mounting hole 14 corresponds to the position of the connecting slot 102, and the fastener 103 can be a bolt. The fastener 103 passes through the bottom of the handlebar 100 into the connecting slot 102 and is then threaded to the mounting hole 14 to fix the housing 1 in the mounting groove 101. In some embodiments, the fastener 103 is equipped with a washer 104. In some embodiments, a sealing groove 1021 is provided at the bottom port of the connecting slot 102, and a rubber plug 105 is installed in the sealing groove 1021.
