In order to achieve the above purpose, the utility model discloses a following technical scheme realizes: the utility model provides a blind helmet is led to intelligence based on STM32, includes helmet infrastructure, helmet infrastructure's inboard and outside cladding have the coating, be provided with the buffering inside lining on helmet infrastructure's the inside lateral wall, a plurality of outer trim of helmet infrastructure's outside fixedly connected with, the buffering inside lining includes two side welts, two the side welt is the symmetric distribution, and the middle part of two side welts has all seted up the fretwork groove, the rear between two side welts just is located helmet infrastructure's inner wall on fixedly connected with back welt.

Preferably, the helmet base framework is of an integrated structure and is manufactured by 3D printing of photosensitive resin.

This foundation frame who sets up the helmet adopts the photosensitive resin that 3D printed, and the material selection pursuit is lightly portable, and structural design is changeed the human body of laminating.

Preferably, the coating layer is made of a carbon fiber cloth material.

Carbon fiber cloth is selected for use as the outside secondary back up coat of helmet foundation frame for this setting, and carbon fiber cloth has advantages such as intensity is big, density is little, and the helmet is firm hard and the quality is light, can satisfy the requirement to the helmet quality.

Preferably, the buffer lining is made of a foamed polyethylene material.

Expanded polystyrene is selected as the internal buffer material of the helmet, the expanded polystyrene has small relative density (1.05g/cm3), and the helmet has the advantages of light weight, low price, low thermal conductivity, impact shock resistance and the like, and can effectively prevent the head of the blind from being damaged when the blind falls down by using the internal buffer material as the helmet lining.

Preferably, a plurality of the outer decoration strips are made of rubber materials.

This setting utilizes rubber materials as outer trim, has improved the shock attenuation performance based on helmet aesthetic property simultaneously.

Preferably, the rear liner plate and the two side liner plates are both provided with arc-shaped panel structures, and the outer walls of the rear liner plate and the outer walls of the two side liner plates are both attached to the inner wall of the helmet base framework.

Advantageous effects

The utility model provides a blind helmet is led to intelligence based on STM 32. Compared with the prior art, the method has the following beneficial effects:

(1) this blind helmet is led to intelligence based on STM32 has soft buffer material inside lining and shock-absorbing rubber layer exterior trim, and the whole integrated design that adopts of helmet, avoids the fixed part to cause the secondary injury to the user under the condition that receives the striking as far as possible, and the danger that structural deformation or sharp object brought can be avoided to the carbon cloth on the same product ectonexine, and the design of whole product will greatly reduced look the risk that the barrier crowd went on a journey and hurt the head.

(2) This blind helmet is led to intelligence based on STM32, the engineering plastics that helmet basic structure was printed for 3d, and the ectonexine carries out the secondary by carbon cloth and consolidates, adopts expanded polystyrene inside lining and rubber layer exterior trim to accomplish shock attenuation, buffering in addition to utilize the fretwork design to subtract heavy, ventilative, when guaranteeing its security and functional, the selection of its material of attention, the burden of weight in order to reduce the visual barrier crowd is lightened as far as possible.
