Description

TECHNICAL FIELD

[0001] The utility model relates to infrared ranging device field, concretely is a novel infrared ranging device. BACKGROUND

[0002] The working principle of the infrared range finder is based on the propagation characteristics of infrared rays. When infrared rays encounter matter (objects or human bodies), they will be reflected. At the same time, the wave band of infrared rays is outside the wave band of visible light, which makes it not be recognized by the human eye and does not affect the visual sense of the user. When the infrared rays are emitted from the range finder and encounter a reflecting object and are reflected back, the range finder receives the reflected signal. By measuring the intensity of the reflected infrared light, the distance between the object and the sensor at that time can be calculated.

[0003] However, the upper cover of the infrared ranging device in the wearing detection device applied to the shared electric vehicle helmet is made of metal, and the protective shell is provided with a through hole for facilitating the transmission of infrared light through the light filter on the light transmission hole and the reception of infrared light. However, if the metal shell of the infrared ranging device is touched by a human hand during use, the capacitive effect of the human body will be coupled into the wearing detection module, thereby interfering with the operation of the capacitive human body sensing device in the module. In addition, the metal shell is provided with a through hole on the light transmission hole, and the production process of the light filter is complex and not suitable for automatic production lines, resulting in low production efficiency.

The material of the upper cover is transparent.

[0006] By adopting the above technical scheme, when the infrared emitter emits red light, the red light transmits through the transparent upper cover. When the infrared light irradiates the helmet or other objects, the infrared receiver captures the intensity of the reflected infrared light to determine the distance and realize ranging. The transparent upper cover protects the internal electronic elements of the infrared ranging device. The light shielding protective sleeve isolates the infrared emitter and the infrared receiver, preventing the infrared emitter from interfering with the infrared receiver when the infrared light is irradiated.

[0007] The utility model further provides that two groups of through holes are formed in the top of the protective sleeve.

[0008] As preferably, the protective sleeve 5 can not affect the use of the infrared emitter 6 and the infrared receiver 7 through the through hole 51.

[0010] As preferably, the protective sleeve 5 of not transparent material quality can protect the infrared emitter 6 and the infrared receiver 7, and also can avoid the use of the infrared receiver 7 when the infrared emitter 6 works.

[0011] Summarized above, the utility model mainly has following beneficial effects:

[0012] The utility model discloses a protective sleeve, upper cover and buckle are set up, and when using, infrared emitter sends red light transmission through transparent upper cover, when infrared light irradiates helmet or other object, infrared receiver captures the intensity of the reflected infrared light and judges distance to realize ranging, and the internal electronic element of infrared ranging device can be protected through the setting transparent upper cover, infrared emitter and infrared receiver are isolated through the setting light protection sleeve, and the infrared receiver is avoided when infrared emitter infrared light irradiation interference.
