[0002] With the development and progress of society, the traffic volume is getting bigger and bigger, and it is more likely to be congested when traveling. More and more people choose to ride. However, some electric vehicles and bicycles do not have a complete indicator light system like cars. Most of them are only equipped with headlights and taillights, and no turn indicators are set, which causes many inconveniences during driving and creates safety hazards.

[0003] In order to ensure the safety of riders, helmets are necessary protective equipment, so some helmets with indicator lights have appeared. However, the existing helmets with indicator lights basically control the on and off of the indicator lights by installing a control module on the handlebars and connecting it to the indicator lights on the helmets through a wireless communication module. However, in actual use, riders often forget to turn on the signal lights when turning due to negligence, or forget to turn off the signal lights after turning, causing the signal lights to always be on, thus failing to achieve the correct warning effect; and the helmet needs to be used with the wireless signal generator on the handlebars, that is, the helmet is bound to the vehicle to a certain extent. When it is necessary to change vehicles, the wireless signal generator also needs to be reinstalled and fixed, which is very inconvenient to use; when riding on vehicles without wireless signal generators, such as shared bicycles and shared electric vehicles, the helmet cannot achieve the corresponding warning effect.

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0028] See also Figure 1-Figure 3 The embodiment of the present invention discloses a head mounted device with a turn indication function, comprising a device body 1 and an indicator light assembly mounted on the device body 1, wherein the indicator light assembly comprises a left turn signal lamp 2, a right turn signal lamp 3, an inductive light control switch 4 and a power supply assembly, wherein the left turn signal lamp 2 and the right turn signal lamp 3 are mounted on both sides of the rear end of the device body 1 respectively;

[0029] The induction light-controlled switch 4 includes a protective shell 41, a first contact piece 42, a second contact piece 43, a rotating shaft 44 and a gravity swing rod 45. The protective shell 41 is a plastic shell and is fixed to the device body 1 by bolts. The first contact piece 42 and the second contact piece 43 are both conductors. The rotating shaft 44 is arranged along the front-to-back direction of the device body 1 and is fixed in the protective shell 41. The first contact piece 42 and the second contact piece 43 are symmetrically installed in the protective shell 41 on both sides of the rotating shaft 44, and the first contact piece 42 is electrically connected to the right turn signal lamp 3, and the second contact piece 43 is electrically connected to the left turn signal lamp 2; the gravity swing rod 45 is rotatably connected to the rotating shaft 44, so that the gravity swing rod 45 adsorbs and electrically connects to the first contact piece 42 or the second contact piece 43;

[0030] The power supply assembly is installed in the device body 1 and is electrically connected to the left turn signal lamp 2 , the right turn signal lamp 3 , the first contact piece 42 , the second contact piece 43 and the gravity swing rod 45 .

[0031] When the head-mounted device of this embodiment is used, the turn signal light can be controlled by swinging the head. Specifically, when the head is tilted to the right at a certain angle, the first contact piece 42 contacts and is electrically connected to the upper end of the gravity swing rod 45, and the right turn signal light is on. When the head is tilted to the left at a certain angle, the second contact piece 43 contacts and is electrically connected to the upper end of the gravity swing rod 45, and the left turn signal light is on.

[0032] The gravity swing rod 45 includes an upper swing rod 451, a lower swing rod 452 and a gravity block 453. One end of the upper swing rod 451 is rotatably connected to the rotating shaft 44 and electrically connected to the power supply assembly, and the other end can be adsorbed and electrically connected to the side of the first contact piece 42 or the second contact piece 43 close to each other; the lower swing rod 452 is arranged in line with the upper swing rod 451 and one end is connected to one end of the upper swing rod 451, and the gravity block 453 is fixed to the other end of the lower swing rod 452. When the head swings, the head-mounted device swings accordingly, and the upper swing rod 451 remains in a vertical state under the action of gravity until the upper swing rod 451 contacts the first contact piece 42 or the second contact piece 43, connecting the circuit of the left turn signal 2 or the right turn signal 3, so that the turn signal lights up. After the head is straightened, the upper swing rod 451 is separated from the first contact piece 42 or the second contact piece 43, the circuit is disconnected, and the turn signal goes out. The tilt of the head can control the turn signal to turn on and off, and the operation is simple, convenient and safe.

[0033] The upper swing rod 451 includes a rotating sleeve 4511, an elastic rod 4512 and a magnetic block 4513. The rotating sleeve 4511 is arranged on the rotating shaft 44. One end of the elastic rod 4512 is connected to the outer wall of the rotating sleeve 4511. The magnetic block 4513 is fixed to the other end of the elastic rod 4512 and is electrically connected to the power supply component. It can absorb and electrically connect the first contact piece 42 or the second contact piece 43. The lower swing rod 452 is arranged colinearly with the elastic rod 4512 and is connected to the outer wall of the rotating sleeve 4511. The elastic rod 4512 has a certain elasticity and can be bent. Therefore, when the head is tilted, the magnetic block 4513 can be adsorbed with the first contact piece 42 or the second contact piece 43. During the process of the head returning to the correct position, the elastic rod 4512 bends, and the magnetic block 4513 can still maintain contact with the first contact piece 42 or the second contact piece 43. When the head is fully returned to the correct position, the elasticity of the elastic rod 4512 reaches the upper limit, which is not enough to support it to remain adsorbed on the first contact piece 42 or the second contact piece 43. At this time, the elastic rod 4512 is also immediately straightened and separated from the first contact piece 42 or the second contact piece 43. This design allows the magnetic block 4513 to be fully adsorbed on the first contact piece 42 or the second contact piece 43 to ensure that the circuit is connected, and it can also prevent the power from being immediately cut off during the process of the head returning to the correct position, and can continue to maintain the circuit connected state for a period of time. The user does not need to maintain a turning posture, which reduces user fatigue.

[0034] The rotating sleeve 4511, the elastic rod 4512 and the magnetic block 4513 are all conductors, and the rotating sleeve 4511 is connected to the power supply assembly to supply power to the magnetic block 4513. The contact surface of the magnetic block 4513 is an inclined surface, or the contact surface of the first contact piece 42 and the contact surface of the second contact piece 43 are inclined surfaces, so that the magnetic block 4513 can be connected with the first contact piece 42 or the second contact piece 43 when in contact, ensuring that the circuit can be connected when connected.

[0035] The gravity block 453 is a lead block.

[0036] The power supply assembly includes a power supply and an electric control board, and the electric control board is electrically connected to the power supply, the left turn signal lamp 2, the right turn signal lamp 3, the first contact piece 42, the second contact piece 43 and the rotating sleeve 4511 respectively.

[0037] The power supply assembly also includes a power switch 5 for controlling the power supply on and off. The power switch 5 is mounted on the device body 1 and its two ends are electrically connected to the electric control board and the power supply, respectively. The power switch 5 is a button-type or touch-type switch. When the indication function is not needed, the power switch 5 can be turned off to prevent accidental touch and save power.

[0038] The power supply assembly further includes a charging socket 6, which is mounted on the device body 1 and electrically connected to a power source. The power source is a rechargeable battery, which is convenient to charge.

[0039] The outer cover of the charging socket 6 is provided with a sealing cover to prevent rainwater or dust from entering.

[0040] The power supply assembly also includes a power display screen 7, which is mounted on the device body 1 and electrically connected to the electric control board so as to timely understand the power status.

[0041] The left turn signal lamp 2 and the right turn signal lamp 3 are both LED lights.

[0042] The indicator light assembly can be directly embedded and installed on the head-mounted device, or it can be integrated into a mounting shell and detachably mounted at a suitable position of the head-mounted device through the mounting shell.

[0043] The head-mounted device is usually a helmet, which can not only protect the rider's head safety but also serve as an indicator. The head-mounted device can also be a hat, a headband, etc.
