[0001] The utility model relates to the technical field of electronic throttle twist grips, in particular to a lightweight electronic throttle twist grip based on a dual Hall sensor. Background Art

[0002] When driving vehicles such as motorcycles and electric tricycles, an electronic throttle twist grip is usually used to control the acceleration and deceleration of the vehicle, and a steel wire, that is, a throttle cable, is used to control the opening degree of the throttle valve.

[0003] When the existing cable-operated throttle controller is in use, the control accuracy is low, the rotation angle of the throttle twist grip is not accurately converted, resulting in a non-linear acceleration process and a certain sense of jerk. Even when the driver is driving normally, it will cause a higher fuel consumption problem.

[0004] Therefore, aiming at the problems of the existing cable-operated throttle controller in use, such as low control accuracy, inaccurate conversion of the rotation angle of the throttle twist grip, non-linear acceleration process, and high fuel consumption, a lightweight electronic throttle twist grip based on a dual Hall sensor can be designed. By setting dual Hall elements, when the throttle core rotates, the throttle core drives the second cavity to rotate synchronously with the magnet, the magnetic field changes, and the dual Hall elements sense the magnetic field change, so as to accurately calculate the rotation angle. Then, the signal is notified to other processing units through the wire harness and connector to make acceleration and deceleration instructions, and cooperate with the engine electronic fuel injection technology to achieve a higher control accuracy.

Detailed implementation manners

[0022] The present utility model will be further described below in conjunction with the accompanying drawings and embodiments.

[0023] Please refer to Figures 1-4 , the present utility model provides an embodiment: a lightweight electronic throttle based on a dual Hall sensor, including a main body 1; further including a first cavity 2, a circuit board 3, a dual Hall element 4, a grip core 5, a second cavity 6 and a magnet 7. The first cavity 2 is installed at the rear position on the left surface of the main body 1, the circuit board 3 is installed inside the first cavity 2, the dual Hall element 4 is arranged on the front surface of the circuit board 3, the grip core 5 is connected to the right side of the main body 1, the second cavity 6 is installed at the rear position on the left surface of the grip core 5, the second cavity 6 is embedded in the right surface of the main body 1, the magnet 7 is arranged inside the second cavity 6, one end of the wire harness 9 is connected to the left side of the circuit board 3, and the other end of the wire harness 9 is connected to a connector 10. By setting the dual Hall element 4, when the grip core 5 rotates, the grip core 5 drives the second cavity 6 and the magnet 7 to rotate synchronously, the magnetic field changes, the dual Hall element 4 senses the magnetic field change, thereby accurately calculating the rotation angle, and then notifying other processing units to issue acceleration and deceleration instructions through the wire harness 9 and the connector 10, so as to achieve a high control accuracy.

[0024] Please refer to Figures 2-4, in this embodiment, both the second cavity 6 and the magnet 7 are arranged in an arc shape. The concentricity of the second cavity 6 and the magnet 7 is the same as that of the main body 1 and the handle core 5. By designing the second cavity 6 and the magnet 7 to be in an arc shape with the same concentricity as the handle core 5, when the handle core 5 is rotated, the moving angle of the magnet 7 can be the same as that of the handle core 5, thereby improving the overall accuracy of the device. A spring 8 is arranged inside the main body 1. The left end of the spring 8 is clamped with a groove arranged inside the main body 1, and the right end of the spring 8 is in contact with the left side surface of the handle core 5. By arranging the spring 8, when the handle core 5 is rotated, the right end of the spring 8 is driven by the handle core 5 to stretch and rotate. After the handle core 5 is released, the spring 8 will generate a restoring force, driving the handle core 5 to quickly reset, providing a good mechanical feedback feel. A wear-resistant ring 11 is embedded and installed at the left side position of the inner surface of the main body 1. By arranging the wear-resistant ring 11, the mechanical friction received by the main body 1 can be reduced, the frictional resistance can be decreased, and the service life can be increased.

[0025] Please refer to Figures 2-4 , in this embodiment, a plurality of circumferentially distributed clamping grooves 12 are formed on the inner surface of the main body 1. A plurality of circumferentially distributed first clamping buckles 13 are machined on the right side surface of the wear-resistant ring 11. The first clamping buckles 13 are matched with the clamping grooves 12. The wear-resistant ring 11 is connected to the main body 1 through the first clamping buckles 13. By arranging the first clamping buckles 13 and the clamping grooves 12, it is convenient for the staff to quickly clamp the wear-resistant ring 11 on the main body 1, improving the installation efficiency. A rubber sleeve 14 is sleeved on the outer surface of the handle core 5. By arranging the rubber sleeve 14, the user's grip can be improved, the friction with the hand can be increased at the same time, and the handle core 5 can be protected, increasing the service life. The surface texture of the rubber sleeve 14 is not protected and is only for illustration. The texture can be changed according to requirements. A sealing glue 16 is filled inside the first cavity 2. By pouring the sealing glue 16, the circuit board 3 can be sealed, the risk of damage to the circuit board 3 can be reduced, and IP67 waterproof and dustproof protection can be provided for the circuit board 3. A plurality of circumferentially distributed second clamping buckles 15 are arranged on the outer surface of the handle core 5 close to the wear-resistant ring 11. The handle core 5 is clamped with the wear-resistant ring 11 through the second clamping buckles 15. By arranging the second clamping buckles 15, it is convenient to position and install the handle core 5.

[0026] When working, by designing the second cavity 6 and the magnet 7 into arcs with the same concentricity as the handle core 5, when the handle core 5 rotates, the moving angle of the magnet 7 can be kept consistent with that of the handle core 5, thereby improving the overall precision of the device. By setting the spring 8, when the handle core 5 rotates, the right end of the spring 8 is driven by the handle core 5 to stretch and rotate. After releasing the handle core 5, the spring 8 will generate a resilience force to drive the handle core 5 to quickly reset, providing a good mechanical feedback feel. By setting the wear-resistant ring 11, the mechanical friction suffered by the main body 1 can be reduced, the frictional resistance can be decreased, and the service life can be increased. By setting the first buckle 13 and the card slot 12, it is convenient for the staff to quickly snap the wear-resistant ring 11 onto the main body 1, improving the installation efficiency. By setting the rubber sleeve 14, the grip feeling of the user can be improved, and at the same time, the friction force with the hand can be increased, and the handle core 5 can be protected, increasing the service life. The surface texture of the rubber sleeve 14 is not protected and is only for illustration, and the texture can vary according to requirements. By pouring the sealant 16, the circuit board 3 can be sealed, the risk of damage to the circuit board 3 can be reduced, and the circuit board 3 can be provided with IP67 waterproof and dustproof protection. By setting the second buckle 15, it is convenient to position and install the handle core 5. The overall device has fewer parts and a simple structure and can be installed inside a motorcycle switch for use.

[0027] Through the above steps, by setting the dual Hall elements 4, when the handle core 5 rotates, the handle core 5 drives the second cavity 6 and the magnet 7 to rotate synchronously, the magnetic field changes, and the dual Hall elements 4 sense the magnetic field change, thereby accurately calculating the rotation angle. Then, through the wire harness 9 and the connector 10, the signal is notified to other processing units to issue acceleration and deceleration commands, so as to achieve a high control precision, thereby solving the problems that existing rotary handle controllers mostly adopt the traditional wire-pulling type, with low control precision and non-linear acceleration, resulting in high fuel consumption.
