[0094] Embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to be used to explain the present invention, but should not be understood as limiting the present invention.

[0095] like Figure 1 As shown, the power control method of the embodiment of the present invention is mainly aimed at a vehicle, and the power control method has a nitrogen mode. The nitrogen mode is a method step in the power control method mainly used for nitrogen acceleration control. Specifically, in the nitrogen mode, the power control method can mainly include the following steps:

[0096] S1: Trigger the start signal. For example, the start signal can be triggered manually, such as Figure 1 As shown, the nitrogen mode can be triggered by twisting the handle, which is Figure 1 Fully turn the handle, that is, turn it to the bottom to trigger the start signal.

[0097] S2: Compare the bus current and the rated current. If the ratio of the bus current to the rated current is not less than the set ratio, the nitrogen mode is started. Otherwise, the nitrogen mode is not started.

[0098] For example, the bus current can be regarded as the current of the UEW line of the vehicle, and the rated current can be regarded as the current value of the vehicle when it is in normal use. When the start signal is triggered, the energy pool of the vehicle will release electrical energy. At this time, the bus current will increase. When the bus current is not less than 85% of the rated current, nitrogen acceleration can be performed. If the bus current is lower than 85% of the rated current, nitrogen acceleration will not be performed even if the start signal is triggered. In this way, the safety of the use of the nitrogen mode can be improved, that is, the nitrogen mode can only be started when the conditions are met.

[0099] It should be noted that the above-mentioned energy pool can be regarded as a power unit specially added to realize the nitrogen mode. The power unit can be a part of the electric energy of the vehicle battery, which can be specifically realized through BMS regulation and management.

[0100] Secondly, the above ratio of 85% is the above set ratio. In some other embodiments, the set ratio can also be adjusted according to different vehicle models, modes, etc. For example, the set ratio can also be 70%, 75%, 80%, etc.

[0101] S3: Monitor the first operating parameter in the nitrogen mode, and turn off the nitrogen mode if the change of the first operating parameter reaches the first preset condition. For example, the first operating parameter can be time, energy consumption, etc. After the nitrogen mode has been running for a period of time, the changes of these first operating parameters can be monitored and compared with the first preset condition. When the first preset condition is reached, the nitrogen mode can be turned off in time, thereby controlling the running time of the nitrogen mode and further ensuring the safety of riding.

[0102] In some embodiments, the first operating parameter includes at least one of the following: the power of the energy pool, the magnitude of the bus current, and the operating time. Specifically, during use, only one of the power of the energy pool, the magnitude of the bus current, and the operating time may be monitored, and the nitrogen mode may be turned off when the corresponding condition is met.

[0103] In some other embodiments, the electric energy of the energy pool, the bus current, and the running time can also be monitored at the same time, and the nitrogen mode can be turned off when any one of the three meets the corresponding first preset condition. This fully ensures that the nitrogen mode can be turned off in time, further ensuring the safety of driving.

[0104] In some embodiments, the first operating parameter is the electric energy of the energy pool, and the first preset condition is the remaining value of the electric energy of the energy pool. If the remaining value is less than the first set threshold, the nitrogen mode is turned off.

[0105] For example, when the nitrogen mode is turned on, the electric energy in the energy pool will gradually be consumed. The electric energy in the energy pool can be displayed as a percentage, and the first set threshold can be a specific value of the percentage, for example, the first set threshold can be 1%, 2%, etc. When the electric energy in the energy pool is completely consumed or is lower than the first set threshold, the corresponding control system will turn off the nitrogen mode. At this time, the vehicle can subsequently run at the rated current again. Figure 1 shown.

[0106] In some embodiments, the first operating parameter is the magnitude of the bus current, and the first preset condition is a comparison between the magnitudes of the bus current and the accumulated current. If the bus current is not greater than the accumulated current, the nitrogen mode is turned off.

[0107] Specifically, the accumulated current can be regarded as the current released by the above-mentioned energy pool. As the electric energy in the energy pool is gradually released, the bus current will also show a downward trend. When the bus current is lower than the accumulated current, the nitrogen mode can be turned off in time.

[0108] In some embodiments, the first operating parameter is the operating time. If the operating time of the nitrogen mode reaches the first preset time, the nitrogen mode is turned off. For example, the first preset time may be 15S. When the operating time of the nitrogen mode reaches 15S, the nitrogen mode can be turned off in time, thereby achieving the purpose of controlling the nitrogen mode in time. In some other embodiments, the first preset time may also be 10S, 12S, 20S, etc.

[0109] In some embodiments, after the nitrogen mode is turned off, the second operating parameter is monitored, and if the second operating parameter reaches a second preset condition, the nitrogen mode is started after the start signal is triggered again.

[0110] For example, the second operating parameter can also be time, corresponding current value, power, etc. When the second operating parameter meets the second preset condition, the nitrogen mode will be started again only when the start signal is triggered again. Otherwise, the nitrogen mode will not be started again, thereby further ensuring driving safety.

[0111] In some embodiments, the second operating parameter includes at least one of the following: a duration of an interval between releasing the accelerator pedal and a remaining value of electrical energy in the energy storage.

[0112] The interval time of releasing the throttle can also be regarded as the interval time from the last time the nitrogen mode was turned off to the time when the nitrogen mode was started again. By monitoring this interval time, the interval time between two nitrogen modes can be within a reasonable range, which is beneficial to improve the safety of operation and reduce damage to components.

[0113] Secondly, since the nitrogen mode is likely to be interrupted due to sudden braking, the electrical energy in the energy pool has not been completely released at this time. By monitoring the remaining value of the power in the energy pool, it can be detected whether the remaining energy can meet the needs of starting the nitrogen mode next time, which is beneficial to shorten the waiting time between two nitrogen modes.

[0114] In some embodiments, the second operating parameter includes the interval time of releasing the throttle and the remaining value of the electrical energy in the energy pool. If the interval time is not less than the second preset time, and if the proportion of the remaining value of the electrical energy in the energy pool is not less than the second set threshold, the nitrogen mode is started after the start signal is triggered again.

[0115] For example, the interval time of releasing the accelerator and the remaining value of the electric energy in the energy pool can be monitored simultaneously, the second set time can be 1S, and the second set threshold can be 10%. When the interval time of releasing the accelerator is not less than 1S, and the remaining power of the energy pool is not less than 10% of the full power of the energy pool, the start signal is triggered again to start the nitrogen mode again. The simultaneous monitoring of these two conditions fully ensures that the nitrogen mode can operate effectively, and further improves the safety of driving.

[0116] In some other embodiments, the second set time duration may also be 2S, 3S, etc., and the second set threshold may also be 20%, 30%, 40%, etc.

[0117] In some embodiments, in nitrogen mode, nitrogen parameters are monitored, including a maximum nitrogen value, a nitrogen consumption value, and a nitrogen recovery value. The maximum nitrogen value can be regarded as the nitrogen value that can be released after the entire nitrogen mode is completely completed, that is, the maximum value allowed in the nitrogen mode, and the maximum nitrogen value may decrease due to the attenuation of the energy pool.

[0118] The nitrogen consumption value can be the actual nitrogen value consumed in the nitrogen mode. The nitrogen recovery value can be the value of nitrogen restored after the nitrogen mode is turned off, that is, the nitrogen recovery value, which can also be regarded as the recovery value of the electric energy in the energy pool.

[0119] By monitoring these parameters, the operation status of the nitrogen mode can be understood in real time, thereby facilitating the regulation and use of the nitrogen mode.

[0120] In some embodiments, the above-mentioned maximum nitrogen value, nitrogen consumption value and nitrogen recovery value can be obtained by i 2 T is calculated, for example, the maximum nitrogen value can be calculated as: (i3 2 -i12)*T1;

[0121] The calculation formula of nitrogen consumption value can be: (i22-i12)*T2;

[0122] The calculation formula of nitrogen recovery value can be: (i22-i4 2 )*T2; where i4≤i1; i2<i4;

[0123] In the formula, i1 is the rated current; i2 is the actual current; i3 is the maximum current value of nitrogen, which can be regarded as the current value when the energy pool is full; i4 is the nitrogen value recovery current, which can be regarded as the current value under the current power of the energy pool; T1 is the nitrogen allowable time, which can be regarded as the entire duration after the nitrogen mode is fully operated; T2 is the actual current operation time, which can be regarded as the actual operation time of the nitrogen mode.

[0124] The above calculation formula facilitates the calculation and acquisition of the above parameters, thereby facilitating the real-time monitoring of the corresponding parameters of the nitrogen mode.

[0125] Next, a vehicle according to an embodiment of the present invention will be described.

[0126] The vehicle of the embodiment of the present invention may include the above-mentioned power control method during use, and the power control method may be the power control method described in any of the above-mentioned embodiments. The vehicle of the embodiment of the present invention may be an electric vehicle, an electric bicycle, a motorcycle, or other vehicles, and of course may also be a sedan, an SUV, or other vehicles. The vehicle of the embodiment of the present invention has a nitrogen function, so as to meet the user's need for extreme speed experience.

[0127] In some embodiments, Figure 2 and Figure 3 As shown, the vehicle includes a throttle assembly 100 , and the throttle assembly 100 includes a frame 11 , a rotor 12 and a switch 13 .

[0128] The rotor 12 is rotatably mounted on the frame 11. For example, Figure 2 As shown, the material of the frame 11 can be plastic, metal, etc. The frame 11 can be generally a columnar structure and can extend in the left-right direction. The rotor 12 can be a handle, which can be a round tube and can extend in the left-right direction. The rotor 12 can be sleeved on the outer peripheral side of the frame 11, and the rotor 12 can rotate freely relative to the frame 11.

[0129] The switch 13 is disposed on one of the frame 11 and the rotor 12 , and the other of the frame 11 and the rotor 12 is provided with a protrusion 121 . The protrusion 121 is used to press the switch 13 to activate the nitrogen mode of the vehicle when the frame 11 and the rotor 12 rotate relative to each other.

[0130] For example, Figure 3 As shown, the switch 13 may be a push-type switch, and the switch 13 may be fixed to the frame 11 by screws or the like. Figure 4 As shown, the protrusion 121 can be provided on the rotor 12. When the rotor 12 rotates relative to the frame 11, the protrusion 121 can push the switch 13 in the radial direction of the frame 11, so that the switch 13 can be turned on. The signal generated by turning on the switch 13 can be used to start the nitrogen mode of the vehicle, thereby facilitating the convenient start of the nitrogen mode.

[0131] In some other embodiments, the switch 13 may also be disposed on the rotor 12 , and the protrusion 121 may also be disposed on the frame 11 .

[0132] The vehicle of the embodiment of the present invention has a nitrogen mode. By providing the switch 13 and the protrusion 121, the nitrogen mode can be turned on by screwing the rotor 12, thereby improving the convenience of the extreme speed experience operation.

[0133] In some embodiments, the vehicle includes a first elastic member 14 , which is disposed between the frame 11 and the rotor 12 , and is used to reset the rotor 12 to an initial position after the rotor 12 rotates relative to the frame 11 .

[0134] For example, Figure 3 As shown, the first elastic member 14 can be a torsion spring, and the first elastic member 14 can be sleeved on the outer peripheral side of the frame 11. One end of the first elastic member 14 can be plugged and assembled with the corresponding hole of the frame 11, and the other end of the first elastic member 14 can be plugged and assembled with the corresponding hole of the rotor 12.

[0135] The initial position is the position maintained by the rotor 12 and the frame 11 when no force is applied or the position is normal. When the rotor 12 rotates relative to the frame 11, the first elastic member 14 will deform and store energy. Under the action of the first elastic member 14, the rotor 12 can automatically reset to the initial position, thereby meeting the use requirement of the rotor 12 to reset itself.

[0136] In some embodiments, the vehicle includes a second elastic member 15 , which is disposed between the frame 11 and the rotor 12 , and is used to offset the elastic force of the first elastic member 14 so that the rotor 12 can remain in an initial position.

[0137] For example, Figure 3 As shown, the second elastic member 15 can be a spring. The second elastic member 15 can be bent and extended along the circumference of the frame 11. One end of the second elastic member 15 can abut against the frame 11, and the other end of the second elastic member 15 can abut against the rotor 12.

[0138] When in use, the rotor 12 can rotate forward and backward relative to the frame 11. Figure 5 As shown, when rotating in the forward direction, the shape of the second elastic member 15 can remain unchanged, while the first elastic member 14 can be deformed and store energy. When rotating in the reverse direction, both the first elastic member 14 and the second elastic member 15 can be deformed and store energy. In this way, the elastic force that the rotor 12 needs to overcome in the forward and reverse rotations can be different, so as to adapt to the use needs of acceleration and braking respectively.

[0139] Secondly, due to the action of the second elastic member 15, the second elastic member 15 can also offset the elastic force of the first elastic member 14, so that the rotor 12 can be maintained in the initial position under the joint elastic action of the first elastic member 14 and the second elastic member 15. Compared with the case of only one elastic member, the stability of the state of the rotor 12 in the initial position is improved.

[0140] In some embodiments, the elastic coefficient of the second elastic member 15 is greater than the elastic coefficient of the first elastic member 14. That is, the elastic force of the second elastic member 15 may be a multiple of the elastic force of the first elastic member 14, specifically, may be two times, three times, four times, etc. Thus, the use requirement of using the second elastic member 15 to offset the elastic force of the first elastic member 14 is met.

[0141] In some embodiments, the rotation of the rotor 12 relative to the frame 11 includes forward rotation and reverse rotation. Figure 5 As shown, the handlebar assembly 100 may be the handlebar assembly 100 on the right side of the vehicle, and the positive rotation may be the backward rotation of the rotor 12, that is, Figure 5 The reverse rotation may be the forward rotation of the rotor 12, that is, Figure 5 Counterclockwise rotation.

[0142] When the rotor 12 rotates forward, the rotor 12 is used to accelerate the vehicle and start the nitrogen mode, and the start of the nitrogen mode lags behind the acceleration of the vehicle. Specifically, when the rotor 12 rotates forward under the action of the human hand, the vehicle accelerates first, and the nitrogen mode is not started until the rotor 12 rotates to the bottom. Therefore, the rotation directions of the acceleration and the nitrogen mode are the same, which meets the needs of actual use.

[0143] When the rotor 12 rotates in the reverse direction, the rotor 12 is used to brake or reverse the vehicle. Figure 5 As shown, a special sensing component may be provided on the rotor 12 and the frame 11. When the rotor 12 rotates in the reverse direction, the sensing component may generate a sensing signal through a relative position change, thereby realizing electronic braking or reverse reversing of the vehicle.

[0144] As a result, the throttle assembly 100 has the functions of acceleration, nitrogen mode, braking, and reversing, which enriches the usage of the throttle assembly 100 and facilitates the user's operation.

[0145] In some embodiments, the protrusion 121 is disposed on the rotor 12 , the second elastic member 15 extends along the rotation direction of the rotor 12 and is disposed between the frame 11 and the protrusion 121 , and in the initial position, the protrusion 121 is located between the switch 13 and the second elastic member 15 .

[0146] For example, Figure 4 As shown, the protrusion 121 can be integrally formed on the rotor 12 by injection molding, and the protrusion 121 can be arranged on the left side of the rotor 12 and can protrude toward the left side of the rotor 12. Figure 5 As shown, at this time, the rotor 12 can be regarded as switched to the initial position. In this position and along the circumferential direction of the rotor 12 , the entire protrusion 121 can be located between the switch 13 and the second elastic member 15 .

[0147] When the rotor 12 rotates forward, the protrusion 121 can move toward the switch 13, and as the protrusion 121 moves, the protrusion 121 squeezes the switch 13 and finally activates the switch 13. When the rotor 12 rotates reversely, the protrusion 121 can push the second elastic member 15, so that the direction of braking or reversing needs to overcome the elastic force of the first elastic member 14 and the second elastic member 15 at the same time, which is conducive to improving the hand feeling experience of braking or reversing.

[0148] In some embodiments, the height dimension of the protrusion 121 along the extension direction of the rotation axis of the rotor 12 increases gradually along the direction of reverse rotation. Figure 4 As shown, the protrusion 121 may be a step structure, and the height dimension of the protrusion 121 in the left-right direction may gradually increase along the direction of reverse rotation.

[0149] For example, the protrusion 121 may include two steps, and the two steps are successively higher along the direction of reverse rotation. The end of the step close to the switch 13 may be an inclined surface. When the rotor 12 rotates, the setting of the inclined surface facilitates the insertion of the protrusion 121 into the gap between the switch 13 and the rotor 12, thereby improving the convenience of operation.

[0150] In some embodiments, the frame 11 is provided with an assembly groove 112, which extends along the circumference of the frame 11, and the second elastic member 15 is assembled in the assembly groove 112. An opening 1121 is provided at one end of the assembly groove 112 facing the protrusion 121, and the opening 1121 is used for the protrusion 121 to move into the assembly groove 112 to squeeze the second elastic member 15 when the rotor 12 rotates in the opposite direction.

[0151] For example, Figures 6 to 8 As shown, the assembly groove 112 can be integrally formed on the frame 11, and the assembly groove 112 can be an arc-shaped groove and can be arranged to extend along the circumference of the frame 11. The second elastic member 15 can be embedded in the assembly groove 112, one end of the second elastic member 15 can be stopped against one end of the assembly groove 112, and the other end of the second elastic member 15 can be stopped against the other end of the assembly groove 112. An opening 1121 can be provided on one side of the assembly groove 112 facing the protrusion 121.

[0152] It should be noted that, due to the limitation of the assembly groove 112, the second elastic member 15 can always be located in the assembly groove 112 and will not extend from the opening 1121 of the assembly groove 112. Therefore, when the rotor 12 rotates forward, the shape of the second elastic member 15 can remain unchanged under the limiting effect of the assembly groove 112, and at this time, only the first elastic member 14 undergoes elastic deformation.

[0153] When the rotor 12 rotates in the reverse direction, the first elastic member 14 undergoes elastic deformation and the protrusion 121 can extend from the opening 1121 into the assembly groove 112, thereby squeezing the second elastic member 15 in the assembly groove 112, thereby increasing the damping effect of braking or reversing.

[0154] The arrangement of the assembly groove 112 can, on the one hand, serve to limit the assembly of the second elastic member 15 and enhance the guiding effect of the compression of the second elastic member 15. On the other hand, the assembly groove 112 can also separate the first elastic member 14 from the second elastic member 15, thereby avoiding interference and contact caused by deformation of the first elastic member 14 and the second elastic member 15 during the rotation of the rotor 12, thereby avoiding friction and jamming between the two and ensuring smooth operation.

[0155] In some embodiments, the vehicle includes a limit block 16 , which is slidably assembled in the assembly groove 112 , and the limit block is located between the second elastic member 15 and the protrusion 121 , and the protrusion 121 is used to push the limit block to achieve compression of the second elastic member 15 .

[0156] For example, Figure 5 and Figure 6 As shown, the limit block 16 can be in a square shape, and the limit block 16 can be assembled in the limit groove and can slide along the extension direction of the limit groove. The limit block 16 is located between the second elastic member 15 and the opening 1121 on the assembly groove 112. The limit block 16 can block the end of the second elastic member 15 from the opening 1121, further preventing the second elastic member 15 from escaping from the assembly groove 112 at the opening 1121. Secondly, the limit block 16 can also be located between the protrusion 121 and the second elastic member 15, so as to improve the compression stability of the protrusion 121 pressing the second elastic member 15.

[0157] Optionally, a circular groove may be provided on the limiting block 16 , and the second elastic member 15 may be plugged into the circular groove, thereby further enhancing the structural stability of the assembly of the limiting block 16 and the second elastic member 15 .

[0158] In some embodiments, the vehicle includes a floating component 17 and a rib 122, one of which is disposed on the frame 11, and the other is disposed on the rotor 12, at least a portion of the floating component 17 can float and displace in the extension direction of the rotation axis of the rotor 12, and the floating component 17 is used to collide with the rib 122 to make a sound when the nitrogen mode is started.

[0159] For example, Figure 5As shown, the frame 11 may be provided with a slot, the slot may extend in the left-right direction, and the slot opening may face the right side, the floating component 17 may be assembled in the slot, and the floating component 17 may float in the left-right direction. The rib 122 may be integrally formed on the rotor 12, and the rib 122 may be triangular.

[0160] When the protrusion 121 activates the switch 13 by squeezing, the floating component 17 will also rotate to the convex rib 122 and touch the convex rib 122. The contact between the two will produce a sound, thereby improving the touch feeling of the nitrogen mode activation and providing sound feedback, thereby improving the operating experience of the nitrogen mode.

[0161] In some embodiments, the floating component 17 includes a slider 171 and a third elastic member 172. The slider 171 is slidably assembled on the frame 11 along the extension direction of the rotation axis of the rotor 12. The third elastic member 172 is arranged between the slider 171 and the frame 11, and the third elastic member 172 is used to elastically push the slider 171 so that the slider 171 can float and move.

[0162] For example, Figure 3 As shown, the slider 171 may be in the shape of a shell, the third elastic member 172 may be a spring, the slider 171 may be slidably assembled on the frame 11 along the left-right direction, and the third elastic member 172 extends along the left-right direction and stops between the frame 11 and the slider 171.

[0163] When in use, the third elastic member 172 can elastically push the slider 171, so that the slider 171 can be displaced and floated in the left and right directions, and the slider 171 can directly contact the above-mentioned rib 122 and make a sound.

[0164] In some embodiments, Figure 3 As shown, the vehicle includes a first induction member 18 and a second induction member 19, the first induction member 18 is arranged on the frame 11, and the second induction member 19 is arranged on the rotor 12. The first induction member 18 and the second induction member 19 are used to output a first signal when the rotor 12 rotates forward relative to the frame 11, and the first signal is used to accelerate the vehicle. The first induction member 18 and the second induction member 19 are used to output a second signal when the rotor 12 rotates reversely relative to the frame 11, and the second signal is used to brake or reverse the vehicle. The first signal and the second signal can be inductive signals, optical signals, etc., so as to meet the use needs of acceleration, braking and reversing.

[0165] Optionally, the first induction element 18 is a Hall sensor, that is, a Hall PCBA component, and the second induction element 19 is a magnet, specifically a tile-shaped magnetic steel.

[0166] In some embodiments, the width of the gap between the first induction element 18 and the second induction element 19 in the radial direction of the frame 11 is 0.8 mm to 1 mm. Figure 8 As shown, the width dimension of the gap between the first sensing element 18 and the second sensing element 19 can be dimension L, and dimension L can be 0.8 mm, 0.9 mm, 1 mm, etc. Thus, interference and contact between the first sensing element 18 and the second sensing element 19 are avoided, and a good sensing signal can be generated between the two.

[0167] In some embodiments, the second induction element 19 extends along the circumference of the rotor 12 , and the central angle corresponding to the second induction element 19 is 60° to 70°.

[0168] For example, Figure 8 As shown, the central angle corresponding to the second sensing element 19 may be angle α, which may be 60°, 65°, 70°, etc. Thus, the sensing stroke between the first sensing element 18 and the second sensing element 19 can fully meet the use requirements of the acceleration and braking strokes.

[0169] In some embodiments, Figure 8 As shown, the second induction member 19 has a first end 191 and a second end 192 arranged opposite to each other in the circumferential direction of the rotor 12, wherein the first end 191 rotates in the positive direction of the rotor 12 (i.e. Figure 8 When rotating clockwise in the middle (in the middle), the second end 192 moves away from the first sensing member 18, and the second end 192 approaches the first sensing member 18.

[0170] In the initial position, the first sensing element 18 is located in the middle of the second sensing element 19, and the central angle of the second sensing element portion between the first sensing element 18 and the first end of the second sensing element 19 is 15° to 30°.

[0171] For example, Figure 8 As shown, the central angle of the second sensing element portion between the first ends of the first sensing element 18 and the second sensing element 19 may be an angle β, and the angle β may be 15°, 20°, 25°, 30°, etc.

[0172] Therefore, in use, the forward rotation angle of the rotor 12 can be 20° to 70°, and the reverse rotation angle of the rotor 12 can be -20° to 0°. Thus, the forward rotation stroke and reverse rotation stroke of the rotor 12 can be adapted to the actual use situation, that is, the use needs of a larger stroke for simultaneous throttle acceleration and nitrogen mode activation are met.

[0173] In some embodiments, the vehicle includes a wire group 20 and a cover plate 21, the frame 11 is provided with a mounting groove 111, the first sensor 18 is connected to the wire group 20 and assembled in the mounting groove 111, the cover plate 21 is provided on the frame 11 and blocks the mounting groove 111, and the wire group 20 passes through the cover plate 21.

[0174] For example, Figure 3 As shown, the first induction member 18 can be welded and fixed with the wire group 20, the mounting groove 111 can be integrally formed on the frame 11, the groove depth direction of the mounting groove 111 can be left-right direction, and the notch of the mounting groove 111 can face the left side. During assembly, the wire group 20 can be passed through the cover plate 21 first, and then the first induction and the corresponding wire group 20 can be inserted into the mounting groove 111, and finally the cover plate 21 can be connected and fixed to the frame 11 by screws. This improves the convenience of installing the first induction member 18.

[0175] In some embodiments, the rotor 12 is provided with a matching groove 123 , the second sensing element 19 is embedded in the matching groove 123 , and the end of the second sensing element 19 in the extending direction is snap-fitted with the groove wall of the matching groove 123 .

[0176] For example, Figure 3 As shown, the matching groove 123 can be integrally formed on the rotor 12, and the notch of the matching groove 123 can face the outside of the rotor 12. Both ends of the second induction member 19 can be provided with protrusions, and the two groove walls of the matching groove 123 opposite to each other in the circumferential direction of the rotor 12 can be provided with slots, respectively. During assembly, the two protrusions of the second induction member 19 can be respectively engaged in the two slots. This ensures the structural stability of the assembly of the second induction member 19 and improves the convenience of assembly.

[0177] In some embodiments, the vehicle includes a pressure plate 22, the pressure plate 22 is disposed on the frame 11, and the switch 13 is fixed to the frame 11 through the pressure plate 22.

During assembly, the handlebar 200 of the vehicle can be inserted into the fixing ring 23, and then the fixing ring 23 can be locked by screws passing through the frame 11. At this time, the fixing ring 23 will be tightened on the outer peripheral side of the handlebar 200, thereby improving the convenience of installation and fixation of the handlebar assembly 100.

[0179] In some embodiments, the vehicle includes a start button, and the vehicle starts the nitrogen mode by operating the start button. For example, the vehicle may be specially equipped with a start button, and multiple start buttons may be provided. The circuits of the multiple start buttons may be connected to resistors of different resistance values.
