Description

Technical Field

[0001] The utility model relates to the technical field of electric bicycles, in particular to a portable helmet fixing component and an electric vehicle. Background Art

[0002] Most of the existing electric bicycle helmets are designed to be fixed in the front basket or under the seat. This not only reduces the storage space in the basket and under the seat, but also makes the design structure of the basket complex. Due to the need to meet various requirements in usage scenarios such as sharing, there are also many problems in the wiring layout. In response to this, setting the helmet on the front panel can solve the problem of compressed storage space. However, since the helmet is externally placed on the vehicle body, a locking component needs to be set to avoid safety problems such as loss. The existing locking components have complex structures and require manual opening and closing, which is inconvenient to operate. Content of the Utility Model

[0036] A positioning frame 11 is provided on the inner side surface of the front panel 4. The positioning frame 11 is recessed from the inner concave card slot 12 towards the inner side surface of the front panel 4. Lock holes 10 corresponding in position are provided on the upper and lower end surfaces of the positioning frame 11. The upper and lower two lock holes 10 form a guiding channel, and a lock tongue 6 is provided in the guiding channel; it can be understood that the upper and lower two lock holes 10 are simultaneously located on the upper and lower side surfaces of the inner concave card slot 12;

[0037] A driving assembly is provided below the positioning frame 11. The lower part of the lock tongue 6 is a transmission portion 62, and the transmission portion 62 is connected to the output of the driving assembly. The upper part of the lock tongue 6 is a positioning portion 61;

[0038] The lock tongue 6 moves along the guiding channel under the drive of the driving assembly, so that the top end of the positioning portion 61 extends upward out of the upper lock hole 10 or disengages downward from the lower lock hole 10;

[0039] A second sensing member 5 for cooperating with the first sensing member 3 to form a magnetic sensor is provided on the positioning frame 11;

[0040] A controller 9 is provided on the positioning frame 11, which is connected to the control module of the driving assembly and is connected to the second sensing member 5.

[0041] As a preferred embodiment, the structure of the driving assembly includes a motor 8 and a screw 7, and the output shaft of the motor 8 is connected to the screw 7. The motor 8 is fixedly arranged on the mounting plate located at the lower part of the positioning frame 11.

[0042] As a preferred embodiment, the transmission part 62 at the lower part of the locking tongue 6 is a rack, which meshes with the screw rod 7.

The controller 9 sends a signal to the motor 2, and the motor 2 starts. The locking tongue 6 is driven by the screw rod 7 to move upward. The positioning part 61 passes through the lower locking hole 10, the positioning hole 2 and the upper locking hole 10 in sequence, so that the locking tongue 6 is closed, and the helmet 1 is locked to the front panel 4.

[0050] When it is necessary to remove the helmet from the front panel, the motor 2 starts, and the locking tongue 6 is driven by the screw rod 7 to move downward. The positioning part 61 of the locking tongue 6 disengages from the upper locking hole 10, the positioning hole 2 and the lower locking hole 10 in sequence, and the helmet 1 is removed from the concave clamping groove 12 on the front panel 4. The first and second sensing parts generate sensing signals to determine that the helmet 1 is removed, and transmit the signals to the controller 9. The controller 9 sends a signal to the motor 2, and the motor 2 stops working.
