Detailed Description
In the following description, for purposes of explanation, numerous implementation details are set forth in order to provide a thorough understanding of the various embodiments of the present invention. It should be understood, however, that these implementation details are not to be interpreted as limiting the invention. That is, in some embodiments of the invention, such implementation details are not necessary. In addition, some conventional structures and components are shown in simplified schematic form in the drawings.
In addition, the descriptions related to the first, the second, etc. in the present invention are only used for description purposes, do not particularly refer to an order or sequence, and do not limit the present invention, but only distinguish components or operations described in the same technical terms, and are not understood to indicate or imply relative importance or implicitly indicate the number of indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one such feature. In addition, technical solutions between various embodiments may be combined with each other, but must be realized by a person skilled in the art, and when the technical solutions are contradictory or cannot be realized, such a combination should not be considered to exist, and is not within the protection scope of the present invention.
Example one
As shown in fig. 1, fig. 1 is a flowchart of a method for locking a vehicle safely according to a first embodiment. The method for safely locking the vehicle comprises the following steps
S1: carrying out locking operation; the locking operation may be an operation performed after receiving the locking instruction, or may be a locking operation performed manually.
S2: comparing the current running speed with a preset speed value;
s21: if the current running speed is higher than the preset speed value, the locking part 2 cannot be clamped into a locking notch 111 which is formed on the locking part 1 and is matched with the locking part 2, so that locking cannot be realized;
s22: if the current running speed is lower than the preset speed value, the locking part 2 is clamped into a locking notch 111 which is formed on the locking part 1 and is matched with the locking part 2, and locking is achieved.
It should be noted that the preset speed value in this embodiment is not a fixed value, but the structures of the locking portion 1 and the latching portion 2 are determined according to the preset speed value, and through experimental verification, the preset speed value is set to 3km/h for explanation, and meanwhile, it is defined that the running speed is greater than 3km/h for high speed or fast running, and the running speed is less than 3km/h for low speed running. If the preset speed value needs to be increased or decreased, only the matching condition between the locking notch 111 and the locking portion 2 needs to be modified correspondingly, and the modification can be verified through experiments.
During the specific application, lock portion 1 can set up on wheel hub, and simultaneously, lock portion 1 will rotate along with the wheel is synchronous together, through stopping lock portion 1, realizes the locking to whole wheel, and then reaches the effect of locking the car.
It should be further explained that the comparison between the current running speed and the preset speed value is performed without any controller, that is, the comparison between the current running speed and the preset speed value is only a general expression, and as for whether the current running speed is greater than or less than the preset speed value, no special device is required to be arranged for comparison, and when the current running speed is greater than the preset speed value, the latch portion 2 cannot be naturally latched into the latch notch 111; on the contrary, when the current driving speed is lower than the preset speed value, the latch 2 may be naturally latched into the locking notch 111. In other words, there are two situations of locking during actual use:
the first condition is that the current running speed is greater than a preset speed value, namely the current running speed is greater than 3km/h, because the locking part 1 rotates along with the wheel, the time for the locking part 111 to slide over the locking part 2 is shorter than the time for the locking part 2 to be clamped into the locking part 111, therefore, the locking part 2 cannot be completely clamped into the locking part 111, the locking part 1 cannot be stopped, the wheel cannot be stopped to rotate, the bicycle or the electric vehicle can continue to run, the damage to a user caused by sudden stopping in the process of fast running is well avoided, and the safety performance is improved.
The second situation is that the current running speed is lower than the preset speed value, that is, the current running speed is lower than 3km/h, since the locking part 1 rotates along with the wheel, the time for the locking notch 111 to slide over the locking part 2 is longer than the time for the locking part 2 to be clamped into the locking notch 111, therefore, the locking part 2 can be completely clamped into the locking notch 111, the locking part 1 is stopped, the wheel also stops rotating, and the bicycle or electric vehicle can stop running; due to the fact that the driving speed is low, even if the vehicle is locked suddenly, the user cannot be damaged greatly.
Preferably, the method for safely locking the vehicle further comprises the following steps:
s3: before comparing the current running speed with a preset speed value, judging the current running speed, and judging whether the current running speed is zero or not;
s31: if the current running speed is zero, locking is realized;
s32: if the current running speed is not zero, the process proceeds to step S2.
Further preferably, the current driving speed is monitored and fed back by arranging a vibration sensor (not shown). When the vibration sensor detects that the current state is in a vibration state, the vibration sensor indicates that the current state is in a motion state, the vibration sensor feeds back the detected information to the main control part (not identified in the figure), and the main control part does not send out a motion instruction of the latch part 2 after receiving the information. When the control of the latch 2 by the main control unit is failed, that is, when the current running speed is not zero, the latch 2 still moves toward the direction of approaching the lock notch 111, and then the process proceeds to step S2.
It should be noted that, since the main control unit is used as a main control component, in practical applications, the main control unit is electrically connected to the vibration sensor and the latch 2 for receiving, processing and transmitting signals.
Still further preferably, the method for safely locking the vehicle further comprises:
s4: after the latch portion 2 is engaged into the lock opening 111 to lock the vehicle, the support portion 5 abuts against the latch portion 2 to support the latch portion 2, so that the latch portion 2 is held in the engaged state in the lock opening 111. Through the setting of supporting part 5, increased the power that latch portion 2 blocked locking portion 1, prevented locking portion 1 from rotating by force and pushed the phenomenon of latch portion 2 out fore shaft 111, promoted the security after the lock car.
Preferably, the method for safely locking the vehicle further comprises the following steps:
s5: when the lock is unlocked, the driving part 3 drives the locking part 2 to move, the locking part 2 is separated from the lock opening 111, and the locking part 1 can rotate freely. The driving part 3 receives the unlocking instruction and starts working, and the output end of the driving part 3 drives the locking part 2 to move, so that unlocking automation is realized. Specifically, the driving unit 3 is electrically connected to the main control unit, and the main control unit sends a command to the driving unit 3 to control the operating state of the driving unit 3.
Further preferably, the method for safely locking the vehicle further comprises the following steps:
s6: when the lock is unlocked, the driving part 3 drives the latch part 2 to move, when the sensing part 4 senses the moving end of the driving part 3, the sensing part 4 sends a signal, so that the driving part 3 stops working, namely, the latch part 2 is separated from the lock opening 111, and the unlocking is completed. Through the setting of response portion 4, the motion precision of latch portion 2 when can promoting the unblock, simultaneously, ensure that latch portion 2 can stop in the assigned position. When the device is applied specifically, the sensing part 4 is electrically connected with the main control part, the sensing part 4 sends a signal to the main control part, and the main control part sends an instruction to control the driving part 3.
In another embodiment, the signal sent by the sensing part 4 can be directly transmitted to the driving part 3, and the driving part 3 stops working after receiving the signal.
In summary, the driving speed is distinguished according to the preset speed value, when the driving speed is greater than the preset value, if a user wants to lock the vehicle, the locking part cannot be clamped into the locking notch and cannot be locked, the locking part continues to rotate along with the hub, sudden stopping in the process of rapid driving is avoided, damage to the user is prevented, and potential safety hazards are greatly reduced; if the running speed is lower than the preset speed value, the locking part can be clamped into the locking notch, the locking stopping part stops rotating, the hub stops moving, locking stopping is achieved, and the potential safety hazard problem does not exist due to the fact that the running speed is low.
