Description

Technical Field

[0001] The utility model relates to the field of protective appliances, and particularly relates to a helmet. Background Art

[0002] A helmet can effectively protect the user's head during daily cycling. Currently, when in use on rainy days, there is generally a problem that rainwater adheres to the lens, affecting the vision. Although the user can form a water film by spraying a hydrophilic spray or isolate and form water droplets by spraying a hydrophobic spray for them to drip off, there are problems such as inconvenient operation and carrying in actual use. Although there are many patent documents in the prior art that also disclose ways to install windshield wipers on helmets to clean water droplets, there is a common problem in the actual implementation process, that is, the lens of the helmet is generally made of plastic material, and its hardness and wear resistance are far less than that of the automotive windshield. Therefore, frequent scraping of the lens by the windshield wiper is very likely to scratch the lens, which is also one of the reasons why the windshield wiper type is difficult to be popularized. Summary of the Utility Model

[0003] Based on the above problems, the purpose of the utility model is to provide a helmet with a beautiful and non-obtrusive overall shape, which can effectively clean the water droplets on the lens, provide safety protection for cycling on rainy days, and avoid scratching the lens.

[0004] In view of the above problems, the following technical solution is provided: A helmet includes a helmet body. A lens is provided in front of the helmet body and is hinged to both sides of the helmet body to realize upward flipping. The helmet further includes a connecting member arranged along the upper arc surface of the lens from left to right when the lens is in the lower buckled state. First and second boxes are respectively provided on both sides of the hinge position between the lens and the helmet body. Both ends of the connecting member are fixedly connected to the first and second boxes respectively. The first box is provided with a control board, a rechargeable battery, a control switch and a charging port connected to the control board. An air pump is provided in the second box. An air passage and a wire passage are provided in the connecting member. The power cord of the air pump passes through the wire passage and is connected to the control board. The air outlet of the air pump is connected to the air passage. A blowing port is provided on the lower side of the connecting member, one end of which is connected to the air passage, and the other end is opened downward and inclined toward the lens.

[0005] In the above structure, the first box body and the second box body are located at the hinge positions on both sides of the lens and the helmet body, effectively reducing the center of gravity, reducing the possibility of the lens falling in the upward-flipped state due to its own weight, and at the same time ensuring the aesthetics of the overall shape and avoiding the situation of blocking the field of vision; the first box body is used to accommodate the control board, rechargeable battery, control switch and charging port, and the second box body is used to accommodate the air pump, making reasonable use of the space of both, and leading the power cord from the first box body to the second box body through the wire channel, effectively hiding the power cord; the air pump supplies air into the air duct and sprays it out from the blowing port. At this time, the air flow blows downward and obliquely towards the lens, so that the water droplets adhering to the lens quickly slide down under the action of their own weight and the blowing of the air flow to ensure the clarity of the field of vision; since the water removal is carried out by means of air flow blowing, the wear of the lens can be effectively avoided. When in use, cooperating with hydrophilic spray or hydrophobic spray can further improve the use effect.

[0006] The utility model is further arranged such that an air curtain area is formed in front of the positions corresponding to the left eye and the right eye of the human body by the connecting member; a plurality of blowing ports are arranged at intervals along the length direction of the connecting member in each air curtain area.

[0007] In the above structure, the air curtain areas are concentrated in front of the positions of the left eye and the right eye of the human body, reducing unnecessary air flow and air pressure loss, and improving the air flow blowing ability of the key area as much as possible on the premise of a fixed air pump flow rate.

[0008] The utility model is further arranged such that the cross-section of the blowing port is rectangular, and its length direction is the same as the length direction of the connecting member.

[0009] In the above structure, the rectangular cross-section is beneficial to forming a continuous air curtain between each blowing port.

[0010] The utility model is further arranged such that the length of the blowing port is 2 mm - 10 mm, and its width is 0.2 mm - 1 mm.

[0011] In the above structure, the length of the blowing port is preferably 3 mm, and its width is preferably 0.3 mm.

[0012] The utility model is further arranged such that the air pump is an electromagnetic vibration type or a motor type.

[0013] In the above structure, the electromagnetic vibration type air pump has the advantages of low power consumption and long battery life, but its air output is lower than that of the motor type; although the motor type air pump has the advantage of large air flow, its power consumption is relatively high, and it can be selected according to the actual use situation.

[0014] The utility model is further arranged such that the second box body is provided with a filtering hole communicated with its inner cavity.

[0015] In the above structure, a sponge filter screen is attached to the orifice of the filtering hole in the inner cavity of the second box body to improve the dust filtering ability.

[0016] The present utility model is further configured such that a partition is provided inside the connecting member, and the partition divides the inner cavity of the connecting member into an air passage and a wire passage.

[0017] In the above structure, the power cord is independently isolated by the partition, preventing the power cord from approaching the air outlet and affecting the air output of the air outlet.

[0018] The present utility model is further configured such that the charging port is located at the lower side of the first box body.

[0019] In the above structure, the possibility of rainwater entering is reduced or avoided in rainy days.

[0020] The present utility model is further configured such that the first box body and the second box body are adhesively fixed to the lens by gluing, double-sided tape, or a polymer anti-slip pad.

[0021] In the above structure, the first box body and the second box body are preferably fixed with 3M double-sided tape.

[0022] The present utility model is further configured such that the connecting member is adhesively fixed to the lens by gluing, double-sided tape, or a polymer anti-slip pad.

[0023] In the above structure, the connecting member is preferably fixed with 3M double-sided tape.

[0024] The beneficial effects of the present utility model are as follows: The first box body and the second box body are located on both sides of the lens at the hinge position with the helmet body, effectively reducing the center of gravity, reducing the possibility of the lens falling in the upwardly flipped state due to its own weight, and at the same time ensuring the aesthetic appearance of the overall shape and avoiding the situation of blocking the field of view; The first box body is used to accommodate the control board, rechargeable battery, control switch, and charging port, and the second box body is used to accommodate the air pump, making reasonable use of the space for both, and guiding the power cord from the first box body to the second box body through the wire passage, effectively hiding the power cord; The air pump supplies air into the air passage and sprays it out from the air outlet. At this time, the air flow blows downward and obliquely towards the lens, causing the water droplets adhering to the lens to quickly slide off under the action of their own weight and the blowing of the air flow to ensure the clarity of the field of view; Since the water removal is achieved by means of air flow blowing, the wear of the lens can be effectively avoided. When used in combination with a hydrophilic spray or a hydrophobic spray, the use effect can be further improved. BRIEF DESCRIPTION OF THE DRAWINGS
