Description
Technical Field
[0001] The utility model belongs to the technical field of electric scooters, and particularly relates to a battery compartment lock for preventing false locking. Background Art
[0002] An electric scooter is a new product following the skateboard. It is easy to transport and store because it can be folded and stored in a small space. In the city, traffic can be a problem for both drivers and pedestrians. Electric scooters can travel quickly and efficiently on streets and bike lanes, avoiding traffic congestion. Electric scooters do not emit polluting gases or make noise. In addition, the use of electric scooters encourages the use of more sustainable and less polluting means of transportation. Electric scooters are cheaper to purchase and maintain than electric bicycles or motorcycles. In addition, the low power consumption of electric scooters makes them very economical to use. However, most of the batteries of electric scooters are installed inside the pedal and covered by a cover plate, or simply locked, which easily causes the battery to fall out of the battery compartment when the electric scooter falls sideways, and the battery is stolen.
[0003] In the prior art, the unlocking of the battery compartment lock without communication in an electric scooter is electronic unlocking, and the locking is mechanical locking. In the actual vehicle side-fall test, there is a phenomenon of false locking of the battery compartment lock. After the side fall, the battery pack falls out of the battery compartment, which has a safety hazard. Since the battery compartment lock of the electric scooter is locked by a mechanical lock, it is necessary to manually judge whether the locking is successful. In the case where the lock catch is not in place, there is a risk of false locking and it is easy to be stolen. Therefore, it is necessary to propose a battery compartment lock for preventing false locking. Summary of the Utility Model
[0004] To solve the above problems, the utility model relates to a battery compartment lock for preventing false locking, which can prevent the battery compartment lock of an electric scooter from being in a false locking state.

[0050] Technical effects of the present utility model: The battery compartment lock adopted in this application is simple to assemble, has high economic benefits, and is applicable to most age groups; the battery compartment lock of this application can firmly lock the battery of the electric scooter, effectively prevent the battery from falling out due to side falls of the electric scooter, and increase the service life of the electric scooter.
[0051] Embodiment 2
[0052] This embodiment provides a battery compartment lock for preventing false locking. Please refer to Figure 3 As shown, it is further designed based on Embodiment 1.
[0053] In the traditional technology, in the unlocked state: send 1 unlocking instruction to the instrument, the instrument sends a periodic unlocking instruction (10 ms / time) to the controller, and then the controller gives a feedback to the instrument module that the lock is open, and the instrument then does not send the periodic unlocking instruction (10 ms / time) to the controller.
[0054] Send an unlocking command to the meter once. The meter sends an unlocking command to the controller once. The controller drives the motor 5 to rotate, pulling the lower buckle 4 and the upper buckle 3 apart. The upper buckle 3 rotates, and the lock catch 1 (vehicle end) pops up to complete unlocking. At this time, the upper buckle 3 presses against the switch 2, the switch 2 is pressed down, and the signal switch line I 7 and the signal switch line II 8 are conducted. The controller feeds back the successful unlocking to the meter, and the meter stops sending the unlocking command. At this time, the battery compartment lock is opened.
[0055] When in the locked state: The signal switch line I 7 and the signal switch line II 8 are not conducted, and the controller feeds back the locked state to the meter.
[0056] The lock catch 1 (vehicle end) is pressed down. After the upper buckle 3 is pressed by the lock catch 1 (vehicle end), it locks with the lower buckle 4 to achieve the purpose of locking the battery compartment.
[0057] In this application, improvements are made to the prior art: When the battery compartment lock is in the unlocking state: Send an unlocking command to the meter module once. The meter module sends a periodic unlocking command (once every 10 ms) to the controller module. The controller drives the motor 5 to rotate, pulling the lower buckle 4 and the upper buckle 3 apart. The upper buckle 3 rotates, and the lock catch 1 (vehicle end) pops up to complete unlocking. At this time, the upper buckle 3 presses against the switch 2, the switch 2 is pressed down, the signal switch is conducted, the controller does not feed back the unlocking information to the meter, and the meter continuously sends a periodic unlocking command (once every 10 ms) to the controller.
[0058] When the battery compartment lock is in the locked state: The lock catch 1 (vehicle end) is pressed down, pressing the upper buckle 3 to rotate. At this time, the switch 2 changes from being pressed down to popping up, and the signal switch line is not conducted. After receiving the locking information, the controller module sends heartbeat data (including the locking information) to the meter module. After receiving the locking information, the meter module stops sending the unlocking command. Because both the controller module and the meter module send information once every 10 ms, while the controller module sends the locking information, the meter module is still sending the unlocking information. Therefore, after receiving the unlocking information, the controller module still executes the control of the battery compartment lock once. The motor 5 rotates, and the motor 5 pulls the lower buckle 4 to rotate. Because the upper buckle 3 is in the pressed state at this time, after the lower buckle 4 rotates, it locks with the upper buckle 3. After completing the locking, at this time, the meter module has received the locking command and stops sending the unlocking command.
[0059] The technical effect of the present utility model: This application changes the original mechanical action of locking into an electronic action. The motor is used to pull the lower buckle, and the lifting and pressing of the lock catch drive the upper buckle to operate to achieve electronic locking. When the lock catch does not rotate in place, there will be no false locking situation. If it is not locked in place, the cover plate will pop up, effectively preventing false locking of the battery compartment lock of the electric scooter, improving the safety performance of the electric scooter, and effectively preventing theft.
[0060] The above are only the preferred embodiments of the present utility model, and thus do not limit the protection scope of the present utility model. For those skilled in the art, the present utility model can have various changes and modifications. Any changes, modifications, substitutions, integrations, and parameter changes made to these embodiments by means of conventional substitutions or capable of achieving the same functions without departing from the principle and spirit of the present utility model fall within the protection scope of the present utility model.
