Description

Technical Field

[0001] The utility model relates to the technical field of AR helmets, in particular to an AR protective helmet. Background Art

[0002] An AR helmet is a smart display helmet that utilizes augmented reality technology. Augmented reality refers to a technology that uses real-time calculations of the camera's position and angle to overlay corresponding images, videos, and 3D models. The goal of this technology is to overlay the virtual world onto the real world on a screen for interactive viewing. As the CPU computing power of portable electronic devices increases, the applications of augmented reality are expected to expand.

[0003] A Chinese patent with authorization announcement number CN212678482U discloses an AR protective helmet, comprising a helmet body, the helmet body comprising a rigid outer shell, an LED display screen embedded in the front of the rigid outer shell, a holographic screen fixedly mounted on the front of the rigid outer shell below the LED display screen, cameras mounted at the four corners of the top of the rigid outer shell, elastic cords fixedly connected to both sides of the bottom of the rigid outer shell, a female buckle fixedly mounted at the bottom of one side of the elastic cord, and a male buckle fixedly mounted at the bottom of the other side of the elastic cord, and a protective pad mounted inside the rigid outer shell. The utility model provides a protective pad, which is made of an elastic material, so that the rigid outer shell transmits the force it receives to the protective pad. When the user wears the helmet body, the protective pad has good cushioning performance, effectively absorbing the impact force applied to the head by the rigid outer shell, further ensuring the safety of the user.

[0004] However, in the implementation of relevant technologies, it was found that the above-mentioned AR protective helmet design has the following problems: the impact force received by the wearer first acts on the rigid outer shell. Since the user's head is in contact with the inside of the rigid outer shell, the rigid outer shell transfers the force received by itself to the protective pad. Since the protective pad is made of elastic material, after the user wears the helmet body, the protective pad has good cushioning performance and effectively absorbs the impact force of the rigid outer shell on the head, further ensuring the safety of the user. However, wearing the helmet for a long time will make the wearer feel stuffy, thereby affecting the user experience. Utility Model Content

[0027] The helmet unit 100 includes a helmet body 101 and a first connecting plate 102 symmetrically mounted on both sides of the helmet body 101. A fixed shaft is fixedly connected to the side of the first connecting plate 102 away from the helmet body 101, and a second connecting plate 103 is fixedly connected to the side of the fixed shaft away from the helmet body 101. The helmet body 101 protects the user's head safety.

[0028] The heat dissipation unit 300 includes a mounting box 301 fixedly mounted on the top of the helmet body 101, a rotating rod 306 is symmetrically mounted on the inner cavity of the second connecting plate 103, both ends of the rotating rod 306 are fixedly connected to a transmission wheel 308, a transmission belt 307 is sleeved on the outer surface of the transmission wheel 308, a motor 305 is fixedly mounted on one side of the mounting box 301, the output end of the motor 305 passes through one side of the mounting box 301 and is fixedly connected to the rotating rod 306, a baffle 309 is fixedly connected to the outer surface of the rotating rod 306, a mounting plate 310 is fixedly connected to the bottom end of the inner cavity of the mounting box 301, a fan 303 is mounted on the bottom end of the mounting plate 310, and the mounting plate 310 is fixedly mounted on the bottom end of the fan 303. A cover 302 is installed on the top of the box 301. When the wearer feels stuffy, he / she opens the cover 302 and starts the motor 305. The motor 305 drives the rotating rod 306 to rotate, and then drives the transmission wheel 308 to rotate. Due to the existence of the transmission belt 307, the two rotating rods 306 can be driven to rotate at the same time. Adjusting the rotation angle of the baffle 309 can increase air flow and cool the inner cavity of the helmet body 101. Starting the fan 303 enhances the cooling effect. The baffle 309 can intercept the flowing dust to a certain extent to prevent excessive dust from blowing into the wearer's head, affecting the user experience, and enhancing the comfort during use.

[0029] A heat dissipation hole 304 is provided at the bottom of the helmet body 101 , and the cross section of the heat dissipation hole 304 is equal to the cross section of the bottom end of the mounting box 301 , so that air can flow into the inner cavity of the helmet body 101 .

[0030] The fixing unit 200 includes a first mounting block 201 fixed to one side of the helmet body 101 , a plug strip 202 is fixedly connected to the bottom end of the first mounting block 201 , a spring buckle 203 is fixedly installed on one side of the plug strip 202 , and is fixed with a connecting strip 205 .

Both the connecting strip 205 and the inserting strip 202 are made of rubber. When the position of the spring clip 203 on the limiting hole 206 is different, the tightness is also different, so that the helmet body 101 can be worn by different people.

[0032] The outer surface of the fixed shaft is movably connected to a lens belt 104, and an AR lens 105 is fixedly installed on one side of the lens belt 104 to improve the field of vision.

[0033] A notch 106 is provided on one side of the helmet body 101 close to the AR lens 105 , and the notch 106 and the AR lens 105 are on the same horizontal plane, so the wearer can fully use the AR lens 105 .
