Description

Technical Field

[0001] The invention relates to the technical field of helmets, and in particular discloses an external heat dissipation device for a motorcycle helmet. Background Art

[0002] There are some urgent problems to be solved in the use of traditional motorcycle helmets, especially in high temperature environments in summer. The main function of a motorcycle helmet is to protect the rider's head. Its structural design is usually relatively closed to ensure that it can effectively cushion and protect the head in the event of accidents such as collisions. However, this closed design can easily cause the head to become stuffy and sweaty in hot summer weather. Especially when parking, due to the lack of air flow, the heat from the head cannot be dissipated in time, causing great discomfort to the rider and may even affect the rider's attention and driving safety.

[0003] In order to solve this problem, some motorcycle helmets with heat dissipation functions have appeared on the market. However, most existing heat dissipation solutions use built-in micro fans to dissipate heat. Although this can alleviate the problem of stuffiness in the head to a certain extent, this design requires structural modifications such as opening holes and slots inside the helmet, which destroys the structural safety of the helmet. The safety of a helmet is one of its most important performance indicators. Any damage to the helmet structure may affect its protective effect at a critical moment, which is a hidden danger that cannot be ignored.

[0004] In addition, the existing built-in cooling solution also has the problem of not being able to quickly and directional air supply. Since the fan is installed inside the helmet, its air supply direction and range are limited, making it difficult to achieve high coverage of heat dissipation for all parts of the head. In actual use, riders may not feel a significant cooling effect, especially in some high-heat areas such as the forehead and neck. The heat dissipation effect is poor and cannot meet riders' comfort needs in high-temperature environments.

[0005] In summary, the existing heat dissipation solutions for motorcycle helmets have certain deficiencies in terms of safety, heat dissipation effect, and comfort. A new heat dissipation device is urgently needed to solve these problems in order to improve the rider's experience in high temperature environments while ensuring that the safety performance of the helmet is not affected.

[0040] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0041] The present embodiment discloses an external heat dissipation device for motorcycle helmets, which is installed on a helmet body 1. The helmet body 1 is specifically a full-face motorcycle helmet. A fan base 2, a host 3 and an air guide hose 4 are provided on the helmet body 1.

[0042] Reference Figure 1-3 , the fan base 2 is arranged on the outside of the helmet body 1, and can be connected to the helmet body 1 by setting an adhesive 28; the host 3 includes a fan housing 31, a fan 32 and a power module 33; the fan housing 31 is arranged on the fan base 2, and a quick-release structure for detachable connection between the fan base 2 and the fan housing 31 is provided; the fan 32 is arranged in the fan housing 31, and the fan housing 31 is provided with a ventilation hole 311 for air intake of the fan 32, and a ventilation cavity 5 connected with the fan 32 is provided between the fan base 2 and the fan housing 31; the power module 33 is arranged in the fan housing 31, and is used to supply power to the fan 32 for operation; the air guide hose 4 is arranged in the helmet body 1, and a foam helmet liner (hidden and shown in the accompanying drawings) is provided in the helmet body 1, and the helmet liner is provided with an embedded pipe groove 11 for accommodating the air guide hose 4, and the air guide hose 4 is arranged in the embedded pipe groove 11, and the air guide hose 4 is connected with the ventilation cavity 5, so as to lead the heat dissipation cold air to the inside of the helmet body 1 and blow it toward the head or face.

[0043] By adopting an external fan heat dissipation structure, the air guide hose 4 is arranged in the helmet body 1 to cover the high-heat-generating area of ​​the head, so as to realize fast and directional air supply, achieve the effect of regulating air and cooling, and have high air supply efficiency. In addition, by setting up a fan base 2, no drilling and no modification of the helmet structure are required, which meets the safety certification requirements. Under the premise of not destroying the safety of the helmet structure, the problem of head heat dissipation when the rider uses the helmet is solved. In addition, it also meets the requirements of lightweight, low power consumption and fast disassembly and assembly. Through modular design, the fan housing 31 is built-in with an integrated power module 33. The lithium battery has a long power supply time and supports USB fast charging. When the power is exhausted, the host 3 can be removed from the fan base 2 to replace the host 3 for continuous operation. The power module 33 can be electrically connected to an intelligent control unit including a temperature sensor, etc., to support temperature control sensing (automatic start and stop) or manual switch function dual modes, and the standby power consumption is less than 0.1W.

[0044] In this embodiment, refer to Figure 3-5 The fan 32 is a turbofan, the ventilation hole 311 is located on the axial side of the turbofan 32, and the ventilation chamber 5 is located on the radial side of the turbofan 32. The turbofan 32 has the advantages of low energy consumption and low noise, and a noise reduction design (≤35dB). In addition, the fan base 2 has a mounting portion and a wind chamber portion 52. The mounting portion is located on the outside of the helmet body 1 for connecting the fan housing, and the wind chamber portion 52 spans the bottom edge of the helmet body 1 for connecting the air guide hose 4. The wind chamber portion 52 belongs to at least part of the ventilation chamber 5. By cleverly combining the air inlet and outlet orientation of the turbofan 32 with the structure of the helmet body 1, the heat dissipation device is arranged on the outside of the full-face helmet body 1 near the lower end, achieving high air supply efficiency while meeting the requirements of its small size, and minimizing the impact on the use of the motorcycle helmet.

[0045] As a preferred solution, the mounting portion and the air cavity portion are detachable split structures, the fan base 2 includes a mounting seat 21 and an air cavity seat 22, the mounting portion is formed on the mounting seat 21, the mounting seat 21 is provided with a first ventilation slot 211, the air cavity seat 22 is provided with a second ventilation slot 221, the air cavity seat 22 and the mounting seat 21 are plugged and assembled, and the first ventilation slot 211 and the second ventilation slot 221 are connected to form the air cavity portion 52. By adopting a split structure, it is easy to produce and assemble.

[0046] Specifically, the mounting seat 21 is provided with a connecting arm 23, and a hook is provided on the connecting arm 23, and the air chamber seat 22 is provided with a convex block 24 that matches and engages with the hook. In a further preferred embodiment, the convex block 24 is provided with a plurality of convex blocks arranged at intervals along the plug-in direction. By adopting such a design, combined with the special position layout of the mounting seat 21 and the air chamber seat 22 in the helmet body 1, considering the different thicknesses of the helmet linings in the helmet bodies 1 of different models, the mounting seat 21 can be plugged into the convex blocks at different positions in the air chamber seat 22 to achieve the telescopic adjustment of the axial length of the air chamber portion 52, thereby improving the installation adaptability of the heat dissipation device, and the first ventilation slot 211 and the second ventilation slot 221 are set together to form the air chamber portion 52, and the telescopic adjustment can be applicable to the thickness of the helmet body and the helmet lining, without occupying extra space, and meeting the safety and comfort requirements of wearing a motorcycle helmet. The air chamber seat 22 can preferably be set with a sealing ring 26, so that the docking sealing between the first ventilation slot 211 and the second ventilation slot 221 is better.

[0047] As a preferred embodiment, the wind chamber seat 22 is provided with a plurality of air duct plugs 25 connected to the second ventilation groove 221, and the air guide hose 4 is connected to the air duct plug 25 and distributed along the edge of the helmet lining of the helmet body 1. In addition, an air outlet adjusting member 41 is provided at the end of the air guide hose 4. One end of the air outlet adjusting member 41 is connected to the air guide hose 4 by plugging, and the other end is provided with a radially arranged air outlet. The size of the opening of the air outlet exposed at the edge of the helmet lining can be adjusted by rotating the air outlet adjusting member 41 in the buried pipe groove 11, thereby adjusting the air outlet volume.

[0048] As a preferred solution, the fan housing 31 is provided with a fan mounting portion 312, a battery mounting portion 313 and an air supply portion 51, the battery mounting portion 313 and the air supply portion 51 are respectively located on the radial sides of the fan mounting portion 312, the turbofan 32 is mounted in the fan mounting portion 312, the power module 33 is mounted in the battery mounting portion 313, the air supply portion 51 belongs to at least part of the ventilation cavity 5, and an air guide baffle 314 extending to the air supply portion 51 is provided between the battery mounting portion 313 and the fan mounting portion 312. By adopting the above design, the air supply efficiency of the turbofan 32 is higher, the energy consumption is reduced, and the heat generated by the power module 33 is not easily transferred to the ventilation cavity 5, thereby further improving the cooling effect of cold air.

[0049] See Figure 4In this embodiment, an air guide port is provided at the connection between the air supply portion 51 and the fan mounting portion 312. The inner diameter of the fan mounting portion 312 is larger than the inner diameter of the air guide port, and the inner diameter of the air guide port is smaller than the inner diameter of the air supply portion 51. In this way, when the wind from the fan mounting portion 312 is centrifugally guided to the air guide port by the turbofan 32, the inner diameter suddenly becomes smaller, so that the flow rate increases and the pressure decreases. The pressure difference principle is used to achieve the effect of negative pressure suction, thereby improving the air intake efficiency of the turbofan 32 and reducing energy consumption. At the same time, in this embodiment, An inclined air guide plate is provided near the air guide port of the air supply portion 51. On the one hand, the inclined air guide plate guides the introduced wind toward the ventilation cavity 5. On the other hand, since the diameter of the introduced wind suddenly increases from the air guide port to the air supply portion 51, the flow rate decreases and the air pressure increases. At this time, the inclined air guide plate pushes the cold air from the high-pressure to the low-pressure air cavity portion 52, thereby accelerating the discharge of the cold air. The special structure of the fan housing 31 of this embodiment maximizes the heat dissipation and ventilation effect of the turbofan 32.

[0050] In this embodiment, the quick-release structure includes a plurality of blocks 27 disposed on the mounting seat 21, and a plurality of slots 315 disposed on the fan housing 31 and matched with the blocks 27. The slots 315 and the blocks 27 may be interchanged or both may be provided. As a preferred solution, the blocks 27 are provided with opening wings that tilt outward, so that personnel can more easily break the snap connection between the blocks and the slots with their fingers on the opening wings, making the disassembly process more convenient. Of course, in other embodiments, magnetic attraction or other connection structures may be used instead of the snap-on structure, and the snap-on structure is conducive to the compact design of the heat dissipation device.

[0051] See Figure 6 The steps for installing the external motorcycle helmet heat dissipation device of the present invention are as follows:

[0052] ① Attach the fan base 2 to the top of the right edge of the helmet body 1;

[0053] ② Install the host 3 on the fan base 2;

[0054] ③ Use a special soldering iron 6 to dig out a number of buried pipe grooves 11 on the helmet lining;

[0056] ⑤Complete the installation.

[0057] The working process of the external motorcycle helmet cooling device is as follows:

[0058] Temperature> set temperature to automatically start, or manually start → fan runs → cold air is output / input from the forehead / neck air outlet through the air guide hose.
