DETAILED DESCRIPTION

[0036] The utility model is further described in detail below in conjunction with the accompanying drawings.

[0037] This specific embodiment is merely an explanation of the present invention and is not a limitation of the present invention. After reading this specification, those skilled in the art may make non-creative modifications to the present embodiment as needed, but such modifications are protected by patent law as long as they are within the scope of the claims of the present invention.

[0038] This embodiment relates to a ventilation helmet, referring to Figure 1-Figure 3 , including a helmet shell 100, a top cover 200, a locking device, an elastic reset device and a limiting device.

[0039] A ventilation structure is provided between the helmet shell 100 and the top cover 200, and the top cover 200 is rotatably connected to the helmet shell 100 for opening or closing the ventilation structure. The user can control the opening and closing of the ventilation structure by rotating the top cover 200. When the ventilation structure is opened, the ventilated helmet switches to a ventilation and heat dissipation mode, and when the ventilation structure is closed, the ventilated helmet switches to a rainproof mode.

[0040] The locking device, the elastic reset device and the limit device are all arranged between the top cover 200 and the helmet shell 100. By arranging the limit device between the top cover 200 and the helmet shell 100, the opening angle of the top cover 200 can be limited to prevent the top cover 200 from being over-opened. Excessive opening of the top cover 200 may cause the connection parts between the top cover 200 and the helmet shell 100 to be subjected to stress exceeding the design limit, which may cause structural deformation, loose connection or even breakage in the long term. A locking device and an elastic reset device are provided between the top cover 200 and the helmet shell 100, so that it is easier to open the ventilation structure. When the locking device is opened, under the action of the elastic reset device, the top cover 200 automatically rotates and opens to expose the ventilation structure. At this time, the ventilated helmet switches to the ventilation and heat dissipation mode, and under the action of the limiting device, the top cover 200 can only be opened within the set range; after the top cover 200 is covered, the top cover 200 closes the ventilation structure, and the ventilated helmet switches to the rainproof mode. At this time, the elastic reset device is in a compressed state, and finally the locking device is used to lock the top cover 200 on the helmet shell 100.

[0041] In this embodiment, the rear end of the top cover 200 is rotatably connected to the rear end of the helmet shell 100 via a rotating shaft. The rotation connection point is located at the rear end of the helmet shell 100, which helps to maintain a balanced weight distribution of the entire helmet and avoid excessive center of gravity shift caused by opening or closing the top cover 200, which affects the comfort and stability of wearing. In other embodiments, the rotation connection point between the top cover 200 and the helmet shell 100 can also be set at other positions.

[0042] Reference Figure 1 The top side of the helmet shell 100 is designed as an open 110, and the front side of the helmet shell 100 is provided with a front baffle 120 extending upward. The design of the front baffle 120 can enhance the protection of the ventilated helmet to the head.

[0043] In this embodiment, refer to Figure 1-Figure 3 The ventilation structure includes: a first ventilation hole 121, a second ventilation hole 210 and a ventilation duct 300.

[0044] Specifically, the first ventilation hole 121 is provided on the front baffle 120. When the top cover 200 is rotated to open, the top cover 200 no longer blocks the first ventilation hole 121. At this time, the first ventilation hole 121 is connected to the environment inside and outside the helmet, and effectively plays a role in ventilation and heat dissipation. When the top cover 200 is rotated to close, the top cover 200 blocks or closes the first ventilation hole 121. More specifically, the first ventilation hole 121 is in the shape of a horizontally placed long strip, and is just right for the user's forehead. The forehead is one of the parts of the human head that is more prone to sweating. The first ventilation hole 121 aimed at the forehead can effectively cool and dissipate the forehead, keep the forehead dry, and improve the user experience.

[0045] Specifically, a second ventilation hole 210 corresponding to the front baffle 120 is provided on the front side of the top cover 200. When the top cover 200 is in an open state, the second ventilation hole 210 is aligned with the opening 110 of the helmet shell 100. At this time, the second ventilation hole 210 cooperates with the opening 110 to connect the internal and external environments of the helmet, effectively playing the role of ventilation and heat dissipation. When the top cover 200 is closed, the front baffle 120 will block the second ventilation hole 210. More specifically, the second ventilation hole 210 is also in the shape of a horizontally placed long strip, and its length is shorter than the first ventilation hole 121. The second ventilation hole 210 is aligned with the upper forehead of the user, and cooperates with the first ventilation hole 121 to ventilate and dissipate heat to multiple parts of the forehead, further improving the user experience.

[0046] The ventilation duct 300 is located on both sides of the front baffle 120, in the space enclosed by the helmet shell 100 and the top cover 200. When the top cover 200 is in an open state, the ventilation duct 300 connects the environment inside and outside the helmet, and effectively plays a role in ventilation and heat dissipation. When the top cover 200 is closed, the ventilation duct 300 is closed accordingly. The ventilation duct 300 is aligned with both sides of the user's head, and this position also usually corresponds to the hair on both sides of the user. The ventilation duct 300 can effectively cool and dissipate heat on both sides of the head, increase the air permeability inside the helmet, reduce the stuffiness caused by wearing the helmet for a long time, and improve comfort.

[0047] In this embodiment, when the top cover 200 is closed, the first ventilation hole 121, the second ventilation hole 210 and the ventilation duct 300 are also closed, which can effectively prevent rainwater from drifting into the interior of the helmet, and has a good rainproof effect. At this time, the ventilated helmet switches to the rainproof mode; when the top cover 200 is opened, the first ventilation hole 121, the second ventilation hole 210 and the ventilation duct 300 are also connected to the inside and outside of the helmet, and have a good ventilation and heat dissipation effect. At this time, the ventilated helmet switches to the ventilation and heat dissipation mode

[0048] In other embodiments, the ventilation structure may also be configured to include only one or two of the first ventilation hole 121 , the second ventilation hole 210 and the ventilation passage 300 .

[0049] In this embodiment, a wind deflector 130 corresponding to the ventilation duct 300 and tilted toward the inner upper side is provided on the top circumference of the helmet shell 100. The wind deflector 130 is designed to effectively guide the external air into the inner space of the helmet, thereby increasing the air intake in this area, so that the passing wind first blows to the sides of the head and then blows to the top of the head, which more effectively helps the body dissipate heat and keep cool.

[0050] Reference Figure 4In this embodiment, a third ventilation hole 101 is provided on the rear side of the helmet shell 100, and a fourth ventilation hole 201 is provided on the rear side of the top cover 200. The third ventilation hole 101 and the fourth ventilation hole 201 on the rear side cooperate with the ventilation structure on the front side to form an air convection channel that runs through the front and back during riding, which helps to quickly remove the heat and moisture accumulated in the head and the helmet, and provide good heat dissipation performance. In other embodiments, only the third ventilation hole 101 or the fourth ventilation hole 201 may be provided.

[0051] Reference Figure 5-Figure 8 Specifically in the present embodiment, the limiting device includes a hook portion 220 disposed on the lower side of the top cover 200, and a blocking portion 140 disposed on the helmet shell 100 and corresponding to the upper side of the hook portion 220. When the top cover 200 is opened at a preset angle, the hook portion 220 interacts with the blocking portion 140 to form a physical limit, preventing the top cover 200 from further rotating upward, thereby achieving precise control and positioning of the opening angle of the top cover 200, ensuring that the top cover 200 will not be over-opened, and improving safety. In other embodiments, the limiting device may also adopt other structures, as long as it can limit the opening angle of the top cover 200, such as a spring with one end fixedly connected to the top cover 200 and the other end fixedly connected to the helmet shell 100.

[0052] Reference Figure 7-Figure 8 , a spring groove 150 is provided on the helmet shell 100 along the longitudinal direction. Specifically, the elastic reset device includes: a first spring 151 installed in the spring groove 150, and an abutment column 230 provided on the lower side of the top cover 200 and corresponding to the first spring 151. After the top cover 200 is covered, one end of the first spring 151 abuts against the bottom of the spring groove 150, and the other end abuts against the contact surface 231 of the abutment column 230, and the spring is in a compressed state at this time. The spring is compressed and stores elastic potential energy. Once the locking device is unlocked, the spring uses its own elastic force to push the top cover 200 to open automatically, which is very convenient. In other embodiments, the elastic reset device can also adopt other structures.

[0053] More specifically, the abutment column 230 is disposed beside the hook portion 220 and is integrally formed with the hook portion 220, that is, the structural component can cooperate with the blocking portion 140 of the helmet shell 100 to play a limiting role, and can also squeeze the first spring 151 to cooperate to achieve a reset function. Figure 8 The elastic reset device further includes: a column 152 disposed in the spring slot 150 and protruding toward the top cover 200. The first spring 151 is sleeved on the column 152 to limit the horizontal movement of the first spring 151. In this embodiment, the elastic reset device is provided with two large groups, which are respectively located on both sides of the locking device to maintain the balance of the top cover 200 when it is popped up.

[0054] Reference Figure 9-12 , the locking device is a push-type reset switch. The push-type reset switch allows the user to quickly and easily complete the locking or unlocking operation through a single press action, which greatly improves the convenience of use. Specifically in this embodiment, the locking device includes: a baffle plate 160 fixedly arranged on the inner side of the front end of the helmet shell 100, located on the lower side of the first ventilation hole 121, and having a travel space between the helmet shell 100, a button 170 partially located in the travel space, and the pressing end can extend out of the front side of the helmet shell 100, a second spring 190 with one end abutting against the baffle plate 160 and the other end abutting against the button 170, a lock hook 180 with one end fixedly connected to the button 170 and the other end extending upward and extending out of the travel space, and a locking plate 240 fixedly arranged on the inner side of the front end of the top cover 200 for cooperating with the lock hook 180. The front end surface of the lock hook 180 is an inclined guide surface 181. When the button 170 is pressed, the lock hook 180 moves backward, and the locking plate 240 is freed from the restraint of the lock hook 180. At this time, the top cover 200 is rotated upward and opened under the action of the elastic reset device, and the button 170 is released. The button 170 and the lock hook 180 are reset under the action of the second spring 190; when the top cover 200 is rotated to close, the locking plate 240 slides to the lower side of the lock hook 180 along the guide surface 181, and the locking plate 240 and the lock hook 180 cooperate to lock.

[0055] The working principle of the utility model is as follows: the user presses the push-type reset switch, and under the action of the elastic reset device, the top cover 200 rotates and opens relative to the helmet shell 100 to expose the ventilation structure. At this time, the ventilated helmet switches to the ventilation and heat dissipation mode, and the opening angle of the top cover 200 is limited under the action of the limit device to ensure the safety of the helmet and the effect of ventilation and heat dissipation. When facing rainy days, the user presses the top cover 200 from top to bottom to close it on the helmet shell 100, close the ventilation structure, and the locking device is locked. At this time, the ventilated helmet switches to the rainproof mode.

[0056] The above is only used to illustrate the technical solution of the utility model rather than to limit it. Other modifications or equivalent substitutions made to the technical solution of the utility model by ordinary technicians in this field should be included in the scope of the claims of the utility model as long as they do not depart from the spirit and scope of the technical solution of the utility model.
