[0001] The present invention relates to the technical field of daily necessities, and particularly relates to a motorcycle helmet capable of switching between winter and summer seasonal modes. Background Art

[0002] When people ride a motorcycle, they need to wear a motorcycle helmet to protect their heads. In addition, while meeting the protection function, the motorcycle helmet also needs to meet the requirements of keeping the human head warm in winter and ventilating in summer.

[0003] The patent with the publication number of CN2234199 is a winter and summer dual-purpose helmet, which is particularly suitable for motorcycle drivers. Its structure is that a front helmet rim and a windshield are installed at the front of the helmet body, upper and lower flanges are installed on the left, right and rear helmet rims of the helmet body, a heat preservation and windproof body is installed between the two flanges, and helmet straps are arranged on the left and right sides of the lower edge of the helmet body.

[0004] However, when people use the helmet in the above patent in summer, they need to remove the heat preservation and windproof body, and when using it in winter, they need to install the heat preservation and windproof body. This makes it more troublesome to switch the use mode of the helmet between winter and summer seasons. Therefore, we propose such a convenient motorcycle helmet capable of switching between winter and summer seasonal modes. Summary of the Invention

[0005] In order to overcome the disadvantages that when switching the use mode of a motorcycle helmet between winter and summer seasons in the prior art, it is necessary to disassemble and assemble the heat preservation and windproof body, and the operation is cumbersome, the present invention provides a convenient motorcycle helmet capable of switching between winter and summer seasonal modes.

The goggle is located in front of and below the helmet shell. Mouth baffles are rotatably connected to the fixing frames. The mouth baffles are all located in front of and below the goggle. The mouth baffles on the left and right sides are engaged. It further includes a blowing mechanism and a heat preservation mechanism. A blowing mechanism for driving air to slowly enter the helmet shell is provided at the upper front part of the helmet shell. A heat preservation mechanism for keeping the head of the user warm is provided on the fixing frame. By inflating and deflating the heat preservation mechanism, the ventilation mode and the heat preservation mode are switched.

[0007] Furthermore, the blowing mechanism includes a flap, a fixed shaft and a torsion spring. Ventilation holes are evenly opened from top to bottom in the middle of the upper front part of the helmet shell. Fixed shafts are evenly connected from top to bottom on the left and right sides of the middle of the upper front part of the helmet shell. The fixed shafts on the same horizontal line are located in the same ventilation hole. A flap is rotatably connected between the fixed shafts on the same horizontal line. Each flap corresponds to a ventilation hole. The flaps are all located in the corresponding ventilation holes. Torsion springs are wound around the fixed shafts. The inner and outer ends of the torsion springs are respectively connected to the flap and the fixed shaft.

[0008] Furthermore, the warming mechanism includes an air release valve, a pump, a piston rod, a long tension spring, a short pull rope, a trachea, and an airbag. Pumps are installed on the fixing frames. The piston rods are slidably connected inside the pumps. Short pull ropes are connected to the front sides of the piston rods. The short pull ropes on the left and right sides are respectively connected to the mouth baffles on the left and right sides. Tracheas are connected to the pumps. The tracheas are communicated with the pumps. The inner wall of the helmet shell is connected with an airbag. The tracheas are communicated with the airbag. An air release valve is installed on the airbag. Long tension springs are wound around the piston rods. The front and rear ends of the long tension springs are respectively connected to the piston rods and the pumps.

[0009] Furthermore, it further includes a protection mechanism for preventing strong winds, rain, and snow from entering the helmet shell and protecting the head of the user. The protection mechanism includes a latch, a slide rod, a sliding frame, and a flip cover. Latches are installed on the flap boards. The sliding frame is slidably connected to the upper right side of the front upper part of the helmet shell. The flip cover is rotatably connected to the upper right side of the helmet shell. The flip cover presses on the upper right part of the sliding frame. Slide rods are installed on the left side of the sliding frame from top to bottom. The slide rods are used to fix the latches. When the sliding frame slides forward and downward, the slide rods slide forward and downward. When the slide rods slide forward and downward, they squeeze the latches to rotate forward and downward, driving the flap boards to rotate forward and downward to block the ventilation holes.

[0010] Furthermore, it further includes an additional layer mechanism for adding warming components. The additional layer mechanism includes a helmet inner shell, a cotton layer, and telescopic shafts. The helmet inner shell is installed on the inner wall of the helmet shell. Telescopic shafts are symmetrically installed on the left and right sides of the front side of the helmet inner shell from top to bottom evenly. The inside of the telescopic shafts is the fixed part, and the outside of the telescopic shafts is the telescopic part. Telescopic springs are provided between the telescopic parts and the fixed parts of the telescopic shafts. The cotton layer is detachably installed between the telescopic shafts. The cotton layer contacts the inner wall of the helmet inner shell.

[0011] Furthermore, it further includes a cleaning mechanism for cleaning the inner and outer sides of the goggles. The cleaning mechanism includes a fixed block, a short tension spring, a cleaning frame, and a long pull rope. Fixed blocks are installed on the upper parts of the fixing frames. The cleaning frame is slidably connected between the fixed blocks on the left and right sides. The goggles are located between the front and rear parts of the cleaning frame. A short tension spring is connected between the left side of the cleaning frame and the left fixed block. A short tension spring is also connected between the right side of the cleaning frame and the right fixed block. A long pull rope is connected to the lower left part of the cleaning frame.

Detailed implementation manners

[0035] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0036] Embodiment 1

[0037] A motorcycle helmet capable of switching between winter and summer season modes, such as Figure 1 , Figure 2 and Figure 3As shown in the figure, it includes a helmet shell 1, goggles 2, a mouth baffle 3, a fixing bracket 31, a blowing mechanism 4 and a warming mechanism 5. The number of the fixing brackets 31 is two, and the two fixing brackets 31 are respectively fixedly connected to the left and right sides of the helmet shell 1. The goggles 2 are rotatably connected between the fixing brackets 31. The goggles 2 are located at the front lower part of the helmet shell 1. The number of the mouth baffles 3 is two, and the two mouth baffles 3 are respectively rotatably connected to the two fixing brackets 31. The mouth baffles 3 are both located at the front lower part of the goggles 2. The mouth baffles 3 on the left and right sides are engaged. A blowing mechanism 4 is provided at the front upper part of the helmet shell 1, and a warming mechanism 5 is provided on the fixing bracket 31.

[0038] As Figure 1 , Figure 2 , Figure 4 and Figure 5 shown, the blowing mechanism 4 includes a flap 41, a fixed shaft 42 and a torsion spring 43. Three ventilation holes 44 are evenly opened from top to bottom in the middle of the front upper part of the helmet shell 1. Three fixed shafts 42 are evenly welded from top to bottom on the left and right sides of the middle of the front upper part of the helmet shell 1. The fixed shafts 42 on the same horizontal line are located in the same ventilation hole 44. A flap 41 is installed between the fixed shafts 42 on the same horizontal line through a bearing. Each flap 41 corresponds to a ventilation hole 44. The flaps 41 are all located in the corresponding ventilation holes 44. Torsion springs 43 are wound on the fixed shafts 42. The inner and outer ends of the torsion springs 43 are respectively connected to the flap 41 and the fixed shaft 42.

[0039] As Figure 1 , Figure 2 , Figure 3 , Figure 6 and Figure 7 shown, the warming mechanism 5 includes an air release valve 51, a pump 52, a piston rod 53, a long tension spring 54, a short pull rope 55, a trachea 56 and an airbag 57. The number of the pumps 52 is two, and the two pumps 52 are respectively fixedly connected to the left and right fixing brackets 31. A piston rod 53 is slidably connected in the pump 52. The number of the short pull ropes 55 is two, and the two short pull ropes 55 are respectively fixedly connected to the front sides of the piston rods 53 on the left and right sides. The short pull ropes 55 on the left and right sides are respectively connected to the mouth baffles 3 on the left and right sides. Tracheas 56 are fixedly connected to the pumps 52. The tracheas 56 are all communicated with the pumps 52. An airbag 57 is connected to the inner wall of the helmet shell 1. The tracheas 56 are all communicated with the airbag 57. The air release valve 51 is installed on the airbag 57. Long tension springs 54 are wound on the piston rods 53. The front and rear ends of the long tension springs 54 are respectively connected to the piston rod 53 and the pump 52.

[0040] Initially, the mouth baffles 3 on the left and right sides are engaged. The mouth baffles 3 pull the short drawstring 55, and the piston rod 53 is pulled out. The long tension spring 54 is in a stretched state. When people need to wear this motorcycle helmet that can switch between winter and summer modes in summer, they can directly put on this motorcycle helmet that can switch between winter and summer modes on their heads. During the use of this motorcycle helmet that can switch between winter and summer modes, the wind directly penetrates into the helmet shell 1 from the lower part of the flap 41, and the wind impacts the flap 41, causing the flap 41 to rotate. The torsion spring 43 undergoes an adaptive deformation, so that the wind gently enters the helmet shell 1, which is conducive to ventilation and improves people's sense of use. When people need to wear this motorcycle helmet that can switch between winter and summer modes in winter, first, people directly put on this motorcycle helmet that can switch between winter and summer modes on their heads. Then, separate the two mouth baffles 3 and rotate the mouth baffles 3 outward. The mouth baffles 3 rotate outward to loosen the short drawstring 55, and the long tension spring 54 resets accordingly, causing the piston rod 53 to move backward and upward, so as to inflate the airbag 57 through the air pump 52. After that, rotate the mouth baffles 3 inward. The mouth baffles 3 rotate inward to pull the short drawstring 55, thereby pulling out the piston rod 53, and the long tension spring 54 is stretched. Subsequently, repeatedly rotate the mouth baffles 3 inward and outward to inflate the airbag 57 and make the airbag 57 expand to the required degree. During the process of inflating the airbag 57, the deflation valve 51 prevents the gas from leaking out of the airbag 57. After the airbag 57 expands, it can block the ventilation holes 44 on the helmet shell 1 and keep the head warm. Then, make the two mouth baffles 3 engage. When using this motorcycle helmet that can switch between winter and summer modes in the next summer, open the deflation valve 51 to deflate the airbag 57, and then close the deflation valve 51 to switch to the ventilation mode. By inflating and deflating the airbag 57, the switching between winter and summer modes can be realized without disassembling and assembling the warming components, and the operation is convenient. When people use this motorcycle helmet that can switch between winter and summer modes, the goggles 2 protect people's eyes. When it is necessary to take off this motorcycle helmet that can switch between winter and summer modes, it can be directly taken off.

[0041] Embodiment 2

[0042] On the basis of Embodiment 1, as Figure 1 、 Figure 2 、 Figure 8 and Figure 9 shown, it further includes a protection mechanism 6. The protection mechanism 6 includes a clamping block 61, a sliding rod 62, a sliding frame 63 and a flipping cover 64. Clamping blocks 61 are welded on the flaps 41. The sliding frame 63 is slidably connected to the upper right front of the helmet shell 1. The flipping cover 64 is rotatably connected to the upper right of the helmet shell 1. The flipping cover 64 presses on the upper right of the sliding frame 63. The number of sliding rods 62 is three. The three sliding rods 62 are installed on the left side of the sliding frame 63 from top to bottom. The sliding rods 62 are used to fix the clamping blocks 61.

[0043] Initially, the flip cover 64 presses the upper right part of the sliding frame 63. When encountering strong wind, rain and snow and the helmet shell 1 does not need to be ventilated, the flip cover 64 is turned left to open, and the flip cover 64 is turned left to loosen the sliding frame 63, and then the sliding frame 63 is pulled forward and downward, and the sliding frame 63 slides forward and downward to drive the sliding rod 62 to slide forward and downward, and the sliding rod 62 slides forward and downward to squeeze the block 61 to rotate forward and downward, thereby driving the flap 41 to rotate forward and downward and block the ventilation hole 44, and the torsion spring 43 undergoes torsional deformation, which can prevent strong wind, rain and snow from entering the helmet shell 1, which is beneficial to protecting the head, and then The slide bar 62 continues to slide forward and downward to insert into the block 61, thereby fixing the flap 41, and then the flip cover 64 is rotated to the right, and the flip cover 64 is rotated to the right to press the sliding frame 63, thereby fixing the sliding frame 63. When the helmet shell 1 needs to be ventilated, the flip cover 64 is rotated to the left again to release the sliding frame 63, and then the sliding frame 63 is pulled upward to its original position, thereby driving the slide bar 62 to slide upward and reset and disengage from the block 61. After that, the torsion spring 43 is reset to make the flap 41 and the block 61 rotate backward and upward to reset, and the flap 41 no longer blocks the ventilation hole 44, so that the helmet shell 1 can be ventilated.

[0044] like Figure 2 , Figure 10 and Figure 11 As shown, it also includes a layer adding mechanism 7, which includes a helmet inner shell 71, a cotton layer 72 and a telescopic shaft 73. The helmet inner shell 71 is installed on the inner wall of the helmet outer shell 1. Six telescopic shafts 73 are evenly fixed from top to bottom on the left and right parts of the front side of the helmet inner shell 71. The inside of the telescopic shaft 73 is a fixed part, and the outside of the telescopic shaft 73 is a telescopic part. The telescopic part of the telescopic shaft 73 and the fixed part of the telescopic shaft 73 are both provided with a telescopic spring. The cotton layer 72 is detachable between the telescopic shafts 73, and the cotton layer 72 is in contact with the inner wall of the helmet inner shell 71.

[0045] When it is necessary to enhance the thermal insulation performance of the motorcycle helmet that can switch between winter and summer modes, the cotton layer 72 is sleeved between the telescopic shafts 73. During the sleeve connection of the cotton layer 72, the telescopic shaft 73 adaptively expands and contracts, and the telescopic spring on the telescopic shaft 73 adaptively deforms, and then the outer wall of the helmet inner shell 71 is attached to the inner wall of the helmet inner shell 71. In this way, the installation of the cotton layer 72 can be completed, and a thermal insulation layer can be added to the helmet outer shell 1, which is beneficial to enhancing the thermal insulation effect. When it is necessary to remove the cotton layer 72, the telescopic part of the telescopic shaft 73 is pressed inward, and the telescopic spring on the telescopic shaft 73 is compressed. Then the cotton layer 72 can be removed, and then the telescopic part of the telescopic shaft 73 is released, and the telescopic spring on the telescopic shaft 73 causes the telescopic part of the telescopic shaft 73 to slide outward and reset.

[0046] like Figure 1 , Figure 2 , Figure 3 ,Figure 12 and Figure 13 As shown in Figure 13 , it further includes a cleaning mechanism 8. The cleaning mechanism 8 includes a fixed block 81, a short tension spring 82, a cleaning frame 83 and a long pulling rope 84. The number of fixed blocks 81 is two, and the two fixed blocks 81 are respectively welded to the upper parts of the fixed frames 31 on the left and right sides. The cleaning frame 83 is slidably connected between the fixed blocks 81 on the left and right sides. The material of the contact part between the cleaning frame 83 and the goggles 2 is a flexible material to prevent the cleaning frame 83 from scratching the goggles 2. The goggles 2 are located between the front and rear parts of the cleaning frame 83. The number of short tension springs 82 is two. One short tension spring 82 is connected between the left side of the cleaning frame 83 and the fixed block 81 on the left side, and the other short tension spring 82 is connected between the right side of the cleaning frame 83 and the fixed block 81 on the right side. The long pulling rope 84 is fixedly connected to the lower left part of the cleaning frame 83.

[0047] When it is necessary to clean the goggles 2, people pull down the long pulling rope 84, so that the cleaning frame 83 moves downward closely against the outer and inner sides of the goggles 2, and the short tension spring 82 is stretched. Then, the cleaning frame 83 moves downward to the limit. In this way, the inner and outer sides of the goggles 2 can be cleaned, which is beneficial to keeping the goggles 2 clean, and there is no need to clean them manually with a cleaning cloth, which is beneficial to improving the cleaning efficiency. When the cleaning frame 83 moves downward to the limit, release the long pulling rope 84, and the short tension spring 82 resets to make the cleaning frame 83 move upward and reset, and clean the goggles 2 again, which is beneficial to improving the cleaning effect.

[0048] As Figure 3 and Figure 14 shown in Figure 14 , it further includes a carrying mechanism 9. The carrying mechanism 9 includes a connecting rod 91 and a rotating rod 92. The connecting rod 91 is welded to the top of the helmet shell 1, and the rotating rod 92 is rotatably connected to the connecting rod 91.

[0049] When it is necessary to carry the motorcycle helmet that can be switched between winter and summer modes, people rotate the rotating rod 92 upward and hold the rotating rod 92, then they can take and carry the motorcycle helmet that can be switched between winter and summer modes. There is no need to hold the entire helmet shell 1 to take it, which is beneficial to convenient taking. When it is necessary to put down the motorcycle helmet that can be switched between winter and summer modes, place the motorcycle helmet that can be switched between winter and summer modes at the designated position and make the rotating rod 92 rotate downward and reset.
