Description

Technical Field

[0001] This utility model belongs to the field of helmets, and specifically relates to a helmet. Background Technology

[0002] A helmet is a device to protect the head and is an indispensable tool when riding electric bikes and motorcycles. For the safety of the user, the user needs to wear a helmet at all times while riding.

[0003] Helmets typically need to completely cover the user's head or the upper part of the head, but this severely affects heat dissipation. Therefore, many helmets have ventilation holes. For example, the waterproof helmet with a ventilation cover disclosed in Chinese utility model patent application CN202122383552.3 includes a helmet body, a waterproof cover, and a ventilation cover. The helmet body has a mounting groove with a downward-facing center on the front side. The center of the mounting groove protrudes upward in the front-back direction to form a stepped surface. A heat dissipation ventilation hole penetrating the inner surface of the helmet body is opened on the stepped surface. The waterproof cover is fitted into the mounting groove, forming a sliding cavity between the waterproof cover and the mounting groove. The waterproof cover has a sliding opening in the front center that faces the heat dissipation ventilation hole. The ventilation cover is located in the sliding opening, and its periphery extends into the sliding cavity to cover the heat dissipation ventilation hole. When the ventilation cover slides backward into the sliding cavity, the heat dissipation ventilation hole is opened. Effect: When the ventilator is in the sliding position to cover the heat dissipation and ventilation holes, water stains are not easily allowed to enter the heat dissipation and ventilation holes around the ventilator, and water stains are also not easily allowed to enter the heat dissipation and ventilation holes around the waterproof cover, making the waterproof effect of this application excellent when ventilation is not required during use.

[0004] In the above structure, air can enter the helmet through the heat dissipation and ventilation holes. However, during the wearing of the helmet, the user's head will block the airflow, thereby affecting the helmet's heat dissipation. This helps to improve the helmet's comfort and facilitate the user's normal driving. Summary of the Invention

[0005] In order to overcome the shortcomings of the prior art, the purpose of this utility model is to provide a helmet with simple structure, good heat dissipation and good comfort.

[0006] The purpose of this utility model is achieved as follows:

[0007] A helmet includes a main body and an outer shell covering the outside of the main body. The main body has an inner cavity. The outer shell has a first air inlet on the front side and the main body has a second air inlet communicating with the first air inlet on the front side. Air can enter the inner cavity through the first air inlet and the second air inlet.

[0008] The top of the inner cavity is provided with a support frame, and a cushioning pad is provided on the support. The support frame and / or the cushioning pad can rest against the top of the user's head, thereby forming an airflow channel between the top of the inner cavity and the user's head.

[0009] The present invention is further configured such that: a first exhaust hole is provided on the rear side of the outer shell, and a second exhaust hole is provided on the rear side of the main body, which communicates with the first exhaust hole; air entering the inner cavity through the first and second air inlets can be discharged from the first and second exhaust holes through the airflow channel.

[0010] The present invention is further configured such that: the support frame extends toward the center of the accommodating cavity to form a plurality of elastic protrusions, the protrusions being disposed on the outer periphery of the buffer pad.

[0011] The present invention is further configured such that: the main body is provided with a plurality of elastic buckles, and the support frame is provided with fixed protrusions adapted to each elastic buckle; under the action of external force, the fixed protrusions can engage with or disengage from the elastic buckles.

[0012] The present invention is further configured such that: a positioning groove is provided on the support frame, a buffer pad is fixedly disposed in the positioning groove, and the buffer pad extends out of the positioning groove and is exposed to the outside.

[0013] The present invention is further configured such that: the support frame is provided with a hollow part, the hollow part extending through the upper and lower sides of the support frame.

[0014] The present invention is further configured such that: a ventilated groove is provided on the inner wall of the receiving cavity, and the second air inlet is connected to the ventilated groove, so that the air entering the receiving cavity through the second air inlet can be guided by the ventilated groove.

[0015] The present invention is further configured such that: a cover is movably provided on the outer shell, the cover can block or seal the first air inlet, thereby reducing or preventing air from entering the inner cavity through the first air inlet.

[0016] The present invention is further configured such that: a first ventilation hole is provided at the top of the outer shell, a cover extends to the top of the outer shell and can block the first ventilation hole, a second ventilation hole communicating with the first ventilation hole is provided at the upper end of the inner cavity, and an air intake gap is provided between the cover and the outer shell, so that air can enter the inner cavity through the air intake gap, the first ventilation hole and the second ventilation hole.

[0017] The present invention is further configured such that: the outer shell is provided with a first sliding groove and a second sliding groove, the first sliding groove and the second sliding groove are inclined, and the cover is provided with sliding parts that are adapted to the first sliding groove and the second sliding groove respectively. The sliding parts slide along the first sliding groove and the second sliding groove respectively to make the cover and the outer shell flip relative to each other and to make the cover move away from the end of the first air inlet.

[0018] The advantages of this utility model compared to the prior art are:

[0019] 1. In this utility model, air can enter the inner cavity through the first and second air inlets. Since the support frame and the buffer pad can form an airflow channel between the top of the inner cavity and the user's head, air can flow to the top and back of the user's head through the airflow channel during use, which is conducive to fully cooling the user's head, improving the helmet's heat dissipation effect, and improving the helmet's comfort. This structure only sets the support frame and the buffer pad in the inner cavity, which is simple in structure and convenient for production and processing.

[0020] 2. The first and second exhaust holes in this utility model facilitate the discharge of air from the inner cavity, which is beneficial for the heat dissipation of the helmet. This structure can also reduce the amount of air discharged from the lower end of the inner cavity during use, which is conducive to improving the comfort of wearing the helmet. The protrusion is conducive to the stable wearing of the helmet and is convenient for the user. This structure can also prevent the helmet from being worn at an angle during use, which would cause the top of the user's head to come into contact with the inner wall of the main body. This is conducive to the airflow in the helmet and the heat dissipation of the user's head.

[0021] 3. The structure of the fixed protrusion and the elastic buckle in this utility model is simple, convenient for production and processing, and facilitates the quick installation and disassembly maintenance of the support frame; the ventilation groove on the inner wall of the cavity can guide the air in the cavity, which can facilitate the uniform heat dissipation of the user's head and improve the comfort of the helmet.

[0022] 4. The positioning groove in this utility model facilitates the positioning and installation of the buffer pad, facilitates the quick assembly of the buffer pad, and helps to prevent the buffer pad from falling off under force, which helps to extend the service life of the helmet. Since the buffer pad passes through the positioning groove and is exposed to the outside, it helps to reduce the force on the user's head and the support frame, which helps to improve the comfort of the helmet, and facilitates the flow of air in the inner cavity over the user's head, thus improving the heat dissipation effect.

[0023] 5. The cover in this utility model allows the user to control the opening and closing of the first air inlet. When heat dissipation is not required or during rain, the user can control the cover to seal the first air inlet, thereby reducing the helmet's heat dissipation and preventing rainwater from entering the helmet through the first air inlet, making it convenient for the user. The design of the first and second ventilation holes helps improve the helmet's heat dissipation effect, and since the cover can block the first ventilation hole, it helps reduce the entry of rainwater or debris into the helmet, making it convenient for the user. The inclined first and second sliding grooves allow the cover to flip relative to the outer shell, making it easier for the front end of the cover to move away from the end of the first air inlet, and also helping to increase the maximum distance between the cover and the outer shell, facilitating air to enter the first air inlet or the first ventilation hole, thus facilitating the helmet's heat dissipation.

Detailed Implementation

[0041] The present invention will be further described below with reference to the accompanying drawings and specific embodiments:

[0042] See Figures 1 to 15 As shown, a helmet includes a main body 2 and an outer shell 1 covering the outside of the main body 2. The main body 2 has an internal cavity 21. A first air inlet 12 is provided on the front side of the outer shell 1, and a second air inlet 22 communicating with the first air inlet 12 is provided on the front side of the main body 2. Air can enter the internal cavity 21 through the first air inlet 12 and the second air inlet 22. A support frame 3 is provided on the top of the internal cavity 21, and a cushioning pad 4 is provided on the support. The support frame 3 and / or the cushioning pad 4 can rest against the top of the user's head, thereby ensuring that the top of the internal cavity 21 is flush with the user's head. An airflow channel is formed between the user's head and the helmet. In this structure, air can enter the inner cavity 21 through the first air inlet 12 and the second air inlet 22. Since the support frame 3 and the buffer pad 4 can form an airflow channel between the top of the inner cavity 21 and the user's head, air can flow to the top and back of the user's head through the airflow channel during use, which is conducive to sufficient cooling of the user's head, improving the helmet's heat dissipation effect and improving the helmet's comfort. In this structure, the support frame 3 and the buffer pad 4 are only set in the inner cavity 21, which is simple and convenient for production and processing.

[0043] The outer shell 1 is provided with an installation cavity 11, and the main body 2 is fixedly installed in the installation cavity 11. In this embodiment, a storage cavity 17 is formed between the front side of the main body 2 and the installation cavity 11. The user's face mirror 5 can be rotated in the storage cavity 17 and stored in the storage cavity 17.

[0044] Preferably, the outer shell 1 has a first exhaust port 13 on its rear side, and the main body 2 has a second exhaust port 23 on its rear side that communicates with the first exhaust port 13. Air entering the inner cavity 21 through the first air inlet 12 and the second air inlet 22 can be discharged through the airflow channel from the first exhaust port 13 and the second exhaust port 23. The arrangement of the first exhaust port 13 and the second exhaust port 23 facilitates the discharge of air from the inner cavity 21, which is convenient for the helmet to dissipate heat. Moreover, this structure can reduce the amount of air discharged from the lower end of the inner cavity 21 during use, which is beneficial to improving the comfort when wearing the helmet.

[0045] The support frame 3 extends toward the center of the inner cavity 21 to form several elastic protrusions 32. The protrusions 32 are located on the outer periphery of the buffer pad 4. The protrusions 32 are conducive to the stable wearing of the helmet and convenient for the user. Moreover, this structure can prevent the helmet from being worn at an angle during use, which would cause the top of the user's head to come into contact with the inner wall of the main body 2. It is also conducive to the airflow in the helmet to dissipate heat from the user's head.

[0046] In this utility model, the main body 2 is provided with a plurality of elastic buckles 26, and the support frame 3 is provided with fixed protrusions 33 adapted to each elastic buckle 26. Under the action of external force, the fixed protrusions 33 can cooperate with or disengage from the elastic buckles 26. The structure of the fixed protrusions 33 and the elastic buckles 26 is simple, convenient for production and processing, and facilitates the quick installation and disassembly and maintenance of the support frame 3. In this embodiment, it is preferable that the outer periphery of the support frame 3 extends to form four mounting arms 31, and each mounting arm 31 is provided with a fixed protrusion 33.

[0047] The support frame 3 is provided with a positioning groove 35, and the buffer pad 4 is fixedly installed in the positioning groove 35. The buffer pad 4 extends out of the positioning groove 35 and is exposed. The positioning groove 35 facilitates the positioning and installation of the buffer pad 4, facilitates the quick assembly of the buffer pad 4, and helps to prevent the buffer pad 4 from falling off under force, which helps to extend the service life of the helmet. Since the buffer pad 4 extends out of the positioning groove 35 and is exposed, it helps to reduce the force on the user's head and the support frame 3, which helps to improve the comfort of the helmet, and facilitates the flow of air in the inner cavity 21 over the user's head, which improves the heat dissipation effect.

[0048] The support frame 3 described in this utility model is provided with a hollow part 34, which runs through the upper and lower sides of the support frame 3. During use, air can come into contact with the user's head through the hollow part 34, which is beneficial to improving the comfort of the helmet. Preferably, the outer periphery of the support frame 3 extends to form at least three mounting arms 31, each mounting arm 31 is provided with a protrusion 32, and preferably the middle part of the support frame 3 and the protrusion 32 are provided with hollow parts 34.

[0049] A cover 6 is movably provided on the outer shell 1. The cover 6 can block or seal the first air inlet 12, thereby reducing or preventing air from entering the inner cavity 21 through the first air inlet 12. The cover 6 makes it convenient for the user to control the opening and closing of the first air inlet 12. When heat dissipation is not required or when it is raining, the user can control the cover 6 to seal the first air inlet 12, thereby reducing the heat dissipation of the helmet and preventing rainwater from entering the helmet through the first air inlet 12, making it convenient for the user.

[0050] The outer shell 1 of this invention is provided with a first ventilation hole 14 at its top. The cover 6 extends to the top of the outer shell 1 and can cover the first ventilation hole 14. The upper end of the inner cavity 21 is provided with a second ventilation hole 24 that communicates with the first ventilation hole 14. An air intake gap is provided between the cover 6 and the outer shell 1. Air can enter the inner cavity 21 through the air intake gap, the first ventilation hole 14 and the second ventilation hole 24. The arrangement of the first ventilation hole 14 and the second ventilation hole 24 is conducive to improving the heat dissipation effect of the helmet. Since the cover 6 can cover the first ventilation hole 14, it is beneficial to reduce the entry of rainwater or debris into the helmet, making it convenient for users to use.

[0051] The outer shell 1 is provided with a first sliding groove 15 and a second sliding groove 16. The first sliding groove 15 and the second sliding groove 16 are inclined. The cover 6 is provided with a sliding part 61 that is adapted to the first sliding groove 15 and the second sliding groove 16 respectively. The sliding part 61 slides along the first sliding groove 15 and the second sliding groove 16 respectively, so that the cover 6 and the outer shell 1 are flipped relative to each other, and the cover 6 is moved away from the end of the first air inlet 12. The inclined first sliding groove 15 and the second sliding groove 16 allow the cover 6 to be flipped relative to the outer shell 1, which makes it easier for the front end of the cover 6 to move away from the end of the first air inlet 12, and also helps to increase the maximum distance between the cover 6 and the outer shell 1, so that air can enter the first air inlet 12 or the first ventilation hole 14, which facilitates the heat dissipation of the helmet.

[0052] To improve the helmet's breathability, a breathable groove 25 is preferably provided on the inner wall of the receiving cavity 21. The second air inlet 22 is connected to the breathable groove 25. Air entering the receiving cavity 21 through the second air inlet 22 can be guided by the breathable groove 25. The breathable groove 25 on the inner wall of the receiving cavity 21 can guide the air in the receiving cavity 21, which facilitates uniform heat dissipation for the user's head and improves the helmet's comfort. In this embodiment, the breathable groove 25 connects the second air inlet 22, the second vent, and the second exhaust port 23.

[0053] The above embodiments are merely preferred embodiments of the present utility model and are not intended to limit the scope of protection of the present utility model. Therefore, all equivalent changes made to the structure, shape, and principle of the present utility model should be covered within the scope of protection of the present utility model.
