Description

Technical Field

[0001] The utility model relates to the technical field of helmets, in particular to a helmet equipped with a quick-mounting and detachable DLP projection device. Background Art

[0002] Cycling vehicles such as motorcycles or electric vehicles do not have a wide rear view like cars. During the driving process, the use of rearview mirrors requires adjusting the body or turning the head to observe the road conditions, which poses a hidden danger to safe driving. Therefore, a panoramic helmet that uses modern electronic equipment to increase the field of view and reduce hidden dangers is very necessary for people who ride and drive. For example, the Chinese patent, the authorization announcement number is CN205409843U, which discloses a rear-view front-release safety smart helmet, in which an optical machine and a front camera are installed in front of the main support through a rocker module. Users can take pictures through the front camera and store them in the memory, and can also start the rear-view camera to project the image onto the optical machine for users to view the situation behind the car. However, although the image of the rear-view camera can be projected onto the optical machine for users to view, the rider needs to check the mobile phone frequently, which greatly reduces the safety and convenience of riding; the structural design of this solution is unreasonable, which will affect the wearing comfort and safety of the helmet. Utility Model Content

[0003] The technical problem to be solved by the utility model is to overcome the shortcomings of the prior art and provide a helmet equipped with a quick-mounting and detachable DLP projection device.

[0004] The technical solution adopted by the utility model is as follows:

[0005] A helmet equipped with a quick-mount and detachable DLP projection device comprises a helmet body and a lens installed in front of the body for wind shielding. The DLP projection device is installed in the body, and the DLP projection device comprises:

[0006] The optical machine DLP is installed below the brim of the main body and is a micro-mirror projector. The optical machine DLP projects toward the front lens and forms a projection area above the lens;

[0007] A control box, mounted on the lower part or the side of the body, the control box comprising a controller, a microphone and a battery;

[0008] A speaker is installed on the top of the body, and the speaker is a bone conduction sensor;

[0009] A rear-view camera is installed at the rear of the body, and at least one rear-view camera is provided, and the rear-view camera is arranged to face backward and collect rear-view video information;

[0010] The video information collected by the rearview camera is sent to the controller, and the controller controls the optical machine DLP to display it in the projection area.

[0011] This technical solution quickly installs a DLP projection device in the helmet, that is, an integrated optical DLP, bone conduction speaker and rear-view camera, to achieve real-time display of riding information, sound transmission and monitoring of rear road conditions, thereby improving the safety and riding experience of riders; the structure also takes into account the needs of quick loading and unloading, which is convenient for maintenance and replacement of parts. Among them: the rear-view camera is installed at the rear of the helmet and is responsible for collecting video information behind the rider. The camera captures images through the lens and converts light signals into electrical signals through the internal image sensor; the optomechanical DLP realizes light reflection or diffusion by controlling the reflection angle of the micromirror. When the micromirror reflects light to the lens, a projection area is formed on the lens, and the rider obtains the required information by looking directly at the image on the lens; after the controller receives the video signal from the rearview camera, it decodes and processes the signal, and sends the processed video information to the optomechanical DLP, which adjusts the reflection state of the micromirror to form a corresponding projection on the lens; the bone conduction speaker transmits the sound signal directly to the rider's skull through vibration, and then transmits it to the inner ear without air conduction, avoiding the interference of environmental noise such as wind during riding, and providing clear voice prompts for the rider.

[0012] In addition, the helmet equipped with the quick-install and detachable DLP projection device according to the utility model also has the following additional technical features:

[0013] According to an embodiment of the utility model, the lens is at least 10 cm away from the optical machine DLP, and a sealing strip is provided between the lens and the body; the lens that slides up and down is always in a closed state with the body through the sealing strip.

[0014] In this technical solution, the normal distance between the lens and the brim of the body is 5cm, while the distance between the improved lens and the brim is at least 10cm. Keeping at least 10cm between the lens and the optical machine DLP helps to diffuse and focus the projected light and optimize the image quality of the projection area. The sealing strip can effectively prevent moisture and dust from entering the interior of the helmet through the gap between the lens and the body, protect the internal optical machine DLP, control box and other key components from damage, and ensure that the helmet can work normally in all weather conditions; reduce external noise from entering the helmet through the gap, improve the sound isolation effect inside the helmet, and provide a quieter riding environment for the rider. When the lens slides up and down, the sealing strip can deform with the movement of the lens, always maintaining close contact with the lens and the body, ensuring effective sealing at any position.

[0015] According to an embodiment of the present invention, the lens is made of a non-transparent material, and the projection area is located in an area above the lens that does not affect riding.

[0016] In this technical solution, the lens is made of non-transparent material, which has a better display effect. The lens made of non-transparent material also has anti-glare properties, which can reduce the interference of sunlight or other strong light on the rider's vision and improve riding comfort. By reasonably designing the brightness and contrast of the projection area, it is ensured that the projection content can be clearly seen under different lighting conditions. Through a helmet equipped with a quick-load and detachable DLP projection device, the rider can view the rear view field, navigation instructions, remaining mileage, estimated arrival time and other information through the projection area above the lens without affecting the front view.

[0017] According to an embodiment of the utility model, the main body is a full-face helmet structure, the control box is located at the bottom of the full-face helmet structure; a waterproof layer is provided at the joint between the control box and the mouth, and the waterproof layer is used to prevent water vapor from entering the interior of the control box. The main body is a half-helmet structure, the control box is located at the side of the half-helmet structure; the control box is provided in the cavity of the main body, the microphone is located on the inner wall of the main body, and the battery is detachably provided on the side of the main body.

[0018] In this technical solution, full-face helmets and half-face helmets are two common forms of motorcycle helmets. Regardless of whether it is a full-face helmet or a half-face helmet, the control box is an important component of the helmet, usually including key components such as a controller, microphone, and battery. Although the specific location of the control box may be different (such as the control box of the full-face helmet is located at the bottom, while the control box of the half-face helmet is located at the side or in the cavity), the main function of the control box is the same, that is, to control various functions of the helmet, such as voice interaction, rear view projection, etc. Whether it is a full-face helmet or a half-face helmet, a waterproof layer will be set at key locations or other waterproof measures will be taken to prevent water vapor from entering the control box and affecting the normal operation of the helmet.

[0019] According to an embodiment of the utility model, a power switch is provided on the side of the body, and the power switch is connected to the lithium battery and starts the control box.

[0020] In this technical solution, the power switch set on the side of the body is the interactive interface between the rider and the helmet power system, and the rider can easily control the power on and off status of the helmet. During motorcycle riding, the rider needs to know the status of the helmet at all times so as to respond to various situations in a timely manner. Through the power switch set on the side, the rider can easily start or turn off the helmet, ensuring that the power can be cut off in time before and after riding, saving energy and extending the service life of the helmet.

[0021] According to an embodiment of the utility model, the optical machine DLP is connected to the brim of the main body through a ball joint, and the optical machine DLP controls the display height of the projection area through the ball joint.

[0022] This technical solution indirectly changes the distance between the optical DLP and the projection surface by adjusting the posture of the ball joint, thereby controlling the display height of the projection area in the rider's field of view. The ball joint has multiple degrees of freedom and can flexibly adapt to different installation angles and postures, so that the optical DLP can be stably fixed on the brim of the hat and can be fine-tuned when necessary to achieve the best projection effect. When riding a motorcycle, the rider needs to pay attention to road conditions and navigation information at all times. By adopting the optical DLP helmet with the described structure, the rider can adjust the projection height of the optical DLP according to the individual's line of sight height and riding posture, so that the navigation information can be accurately displayed in the center of sight or at a suitable position. In this way, the rider does not need to frequently look down at the navigation device, thereby improving the safety and convenience of riding.

[0023] According to one embodiment of the utility model, the control box is built with a Bluetooth module, and the Bluetooth module communicates wirelessly with a mobile phone and receives navigation information transmitted by the mobile phone. The controller controls the optical machine DLP to display the navigation information in the projection area.

[0024] In this technical solution, by using a helmet with Bluetooth communication function, the rider pairs the mobile phone with the helmet control box. The Bluetooth module is responsible for receiving the navigation information transmitted by the mobile phone, and the optical DLP uses projection technology to project the navigation information in the form of images or text into the rider's field of vision. Riders do not need to frequently check their mobile phones or special navigation devices, they only need to look up to see the route instructions ahead, which greatly improves the safety and convenience of riding.

[0025] Compared with the prior art, the utility model has the following beneficial effects:

[0026] By quickly installing a DLP projection device in the helmet, which integrates optical DLP, bone conduction speakers and a rear-view camera, real-time display of riding information, sound transmission and monitoring of rear road conditions can be achieved, thereby improving the rider's safety and riding experience; the structure also takes into account the needs of quick loading and unloading, making it easy to maintain and replace parts.
