Description

Technical Field

[0001] The present invention relates to the field of gear shifting operation control, and in particular to a multiple gear shifting method applied to new energy trucks. Background Art

[0002] Compared with traditional fuel trucks, the shifting method of new energy trucks may be different. New energy trucks generally use electronic gear levers. The electronic shifting method uses sensors and single-chip microcomputers to monitor the driver's operation in real time and collect shifting data information. The data information collected by the sensor is transmitted to the single-chip microcomputer, which performs real-time data processing and judgment, and then outputs corresponding instructions to control the transmission to perform shifting operations. The current electronic shifting operation on the market is single, occupies space, and has a poor driving experience. For this reason, we propose a variety of shifting methods for new energy trucks. Summary of the invention

[0003] In view of the deficiencies in the prior art, the present invention provides a variety of shifting methods applied to new energy trucks, which solve the above-mentioned problems.

[0004] To achieve the above-mentioned purpose, the present invention provides the following technical solution: a plurality of shifting methods applied to new energy trucks, including knob-type photoelectric shifting and toggle-type Hall shifting.

[0005] Preferably, the knob-type photoelectric shift includes a shift operation angle, a shift operation torque and a shift switch signal triggering mode.

[0006] Preferably, the shift operation angle is achieved by rotating the shift knob to drive the φ3 steel ball to move in the shift slot (red area) on the shift block, and the angle between two adjacent slots is designed to be 25 degrees, thereby achieving a shift angle output of 25°.

[0007] Preferably, the shift operating torque is: rotating the shift knob to drive the φ3 steel ball to move in the gear slot (red area) on the shift block. During the movement of the steel ball from the trough to the peak of the gear slot, the shift spring is compressed to achieve shift torque output.

[0008] Preferably, the shift switch signal triggering mode is: In the first step, when the car starts in gear D, the light shielding structure blocks the photoelectric sensor No. 1, causing the sensor to be disconnected, while the photoelectric sensor No. 2 is not blocked and is normally turned on; In the second step, when the shift knob is rotated 25 degrees to switch to the N gear, the No. 1 and No. 2 photoelectric sensors are not blocked by the light shielding structure and are normally turned on; The third step is to rotate the shift knob 25 degrees to switch to the R gear. The photoelectric sensor No. 1 is not blocked by the light shielding structure and is normally turned on. The photoelectric sensor No. 2 is blocked by the light shielding structure and is disconnected. In the fourth step, different gears transmit different signals to the chip inside the switch by blocking different photoelectric sensors, and finally output a communication matrix that meets the requirements to the entire vehicle.

[0009] Preferably, the toggle-type Hall shift includes a shift operation angle, a shift operation torque and a shift switch signal triggering mode.

[0010] Preferably, the shift operation angle is achieved by turning the handle, the handle drives the shift fork to move within the movement area of ​​the shell, there is a limiting structure in the shell, and the angle between the limiting structure and the shift fork is 6°, thereby achieving a shift angle output of 6°.

[0011] Preferably, the shift operating torque is: when the handle is turned, the handle drives the top pin in the shift fork to move in the gear slot (red area) on the shift block, and the shift spring is compressed during the movement of the top pin from the trough to the peak of the gear slot, thereby realizing the shift torque output.

[0012] Preferably, the shift switch signal triggering mode is: The first step, when starting at the D gear, the magnet is located directly above the four Hall sensors, the Hall sensors sense the magnetic field, the magnetic field strength is greater than the Hall sensor's turn-on point Bop, the four Hall sensors simultaneously output low level, we define the low level as 0, the high level as 1, then the output signal is 0000; In the second step, by turning the handle, the handle drives the fork and thus drives the magnet insert to move, and the magnet moves away from Hall sensors No. 2 and No. 4. The magnetic field received by Hall sensors No. 2 and No. 4 changes from strong to weak. When the magnetic field is weaker than the opening point Bop of the Hall sensor, No. 2 and No. 4 change to output high level; while the magnetic field strength received by Hall sensors No. 1 and No. 3 is still greater than the opening point Bop of the Hall sensor, and they continue to output low level. At this time, the signal output is 0011; In the third step, by turning the handle, the handle drives the fork and thus drives the magnet insert to move, and the magnet moves away from Hall sensors 1 and 3. The magnetic field received by Hall sensors 1 and 3 changes from strong to weak. When the magnetic field is weaker than the opening point Bop of the Hall sensor, No. 1 and No. 3 change to output high level; while the magnetic field strength received by Hall sensors 2 and 4 is still greater than the opening point Bop of the Hall sensor, and they continue to output low level. At this time, the signal output is 1100; In the fourth step, different gears receive different magnetic field strengths through the Hall sensor to output different signals to the internal chip, and finally output a communication matrix that meets the requirements to the entire vehicle.

[0013] Compared with the prior art, the present invention provides a variety of shifting methods applied to new energy trucks, which have the following beneficial effects: 1. The multiple gear shifting modes applied to new energy trucks have various operation modes: the gear shifting mode is increased, and the driver only needs to lightly touch the knob or push the push rod to achieve the gear shifting. Two gear shifting modes are provided to improve driving safety.

[0014] 2. The multiple shifting modes applied to new energy trucks save storage space: the electronic shifting eliminates the traditional shift lever and cable, saving more storage space in the cockpit.

[0015] 3. The application of multiple gear shifting modes in new energy trucks improves the driving experience: the microcontroller can decide when to change gears according to the speed, load and driver's operation to ensure the smoothness and accuracy of the gear shifting action.
