[0047] As shown in Figure 2 and Figure 3 The helmet includes a helmet body 1, a liquid sensor 2, an alarm device 3 and a control assembly (not shown in the figure). As shown in Figure 2 and Figure 3As shown, the helmet body 1 is provided with a medium cavity 10, which is filled with liquid and has a certain cushioning and shock absorption effect, which can protect the user's head.

[0048] like Figure 2 As shown, the liquid sensor 2 is installed inside the medium cavity 10 to detect the presence of liquid within the medium cavity 10, and in some cases, it can even detect changes in the liquid level. The liquid sensor 2 can be selected according to requirements.

[0049] like Figure 3 As shown, the alarm device 3 and control component are located on the outside of the medium cavity 10, that is, on the outside of the helmet body 1. This prevents damage from the liquid inside the medium cavity 10, and the alarm device 3 also facilitates the provision of warning signals to the user. The control component is communicatively connected to both the liquid sensor 2 and the alarm device 3. When the liquid sensor 2 detects a lack of liquid in the medium cavity 10, it sends a liquid loss signal to the control component. The control component then controls the alarm device to generate an alarm signal to alert the user. Specifically, when the liquid sensor 2 detects a lack of liquid in the medium cavity 10, it indicates that the helmet's medium cavity 10 is damaged, possibly due to impact, collision, or deformation. This triggers the alarm device 3 to alert the user, ensuring that the user does not wear a damaged helmet and improving riding safety.

[0050] The alarm device 3 can be one of the following: a sound alarm, a visual alarm, a vibration alarm, or a voice alarm. A sound alarm uses a buzzer, horn, or loudspeaker to emit a high-decibel sound to attract the user's attention. A visual alarm provides visual warnings through lights (such as LED lights or flashing lights), a display screen, or signal lights. A vibration alarm alerts the user through vibration and is suitable for noisy environments or people with hearing impairments. A voice alarm uses pre-recorded messages or synthesized voice to convey specific information or instructions.

[0051] Furthermore, the helmet also includes a sealing piston 4 and a monitoring component 5, such as Figure 3 , Figure 4 and Figure 5 As shown, a sealing piston 4 is disposed within the medium chamber 10, dividing the medium chamber 10 into two sealed liquid chambers 11 and a monitoring chamber 12. Liquid fills the liquid chamber 11, and the monitoring component 5 is disposed within the monitoring chamber 12. When the sealing piston 4 moves within the medium chamber 10, the liquid in the liquid chamber 11 will not flow into the monitoring chamber 12, thus protecting the monitoring component 5.

[0052] The monitoring assembly 5 is in communication connection with the alarm device 3. When the helmet is deformed, the liquid cavity 11 is deformed to extrude the liquid to move to one side of the monitoring cavity 12, the liquid pushes the sealing piston 4 to move to one side of the monitoring cavity 12, the sealing piston 4 pushes the monitoring assembly 5 to move to realize circuit conduction, the alarm device 3 is turned on to generate an alarm signal to remind the user, so that the user does not wear the damaged helmet, and the safety of riding is improved. Alternatively, the liquid fills the liquid cavity 11, so that the circuit of the alarm device 3 and the monitoring assembly 5 is conducted to realize the alarm function when the helmet is deformed.

[0053] In the embodiment, the alarm device 3 is connected with the monitoring assembly 5 to form a circuit that can be disconnected or connected. When the helmet is in a normal state, the circuit of the monitoring assembly 5 and the alarm device 3 is disconnected; when the helmet is deformed, the monitoring assembly 5 moves to connect the circuit of the alarm device 3, so that the alarm device 3 alarms to remind.

[0054] As shown in Figure 4 and Figure 5 , the monitoring assembly 5 includes a first metal sheet group 51, a second metal sheet group 52 and an extension rod 53. The first metal sheet group 51 and the second metal sheet group 52 are arranged in parallel in the monitoring cavity 12, and each of the first metal sheet group 51 and the second metal sheet group 52 includes two metal contacts. The two metal contacts of the first metal sheet group 51 and the two metal contacts of the second metal sheet group 52 are in communication connection with the alarm device 3, as shown in Figure 4 . The first metal sheet group 51 and the second metal sheet group 52 are arranged in parallel, which means that the two metal contacts of the first metal sheet group 51 and the two metal contacts of the second metal sheet group 52 are arranged in parallel and opposite to each other, and the two metal contacts of the same metal sheet group are arranged in an up-down interval. When the two metal contacts of the first metal sheet group 51 are connected, a connected circuit is formed between the first metal sheet group 51 and the alarm device 3, and the alarm device 3 generates an alarm signal to alarm and remind. When the two metal contacts of the second metal sheet group 52 are connected, a connected circuit is formed between the second metal sheet group 52 and the alarm device 3, and the alarm device 3 generates an alarm signal to alarm and remind. In the embodiment, the first metal sheet group 51 is located between the sealing piston 4 and the second metal sheet group 52.

[0055] As shown in Figure 5 , the extension rod 53 is arranged in the monitoring cavity 12, one end of the extension rod 53 is connected with the sealing piston 4, and the other end of the extension rod 53 can pass through the two metal contacts to extend between the first metal sheet group 51 and the second metal sheet group 52. The other end of the extension rod 53 is provided with two signal contacts 54, and the two signal contacts 54 are electrically connected. The two signal contacts 54 are located between the first metal sheet group 51 and the second metal sheet group 52 and are arranged opposite to the two metal contacts of the first metal sheet group 51 and the two metal contacts of the second metal sheet group 52, respectively, as shown in Figure 4and Figure 5 as shown.

[0056] When the liquid extrusion sealing piston 4 pushes the extension rod 53 with the two signal contacts 54 to move towards the side where the second metal sheet group 52 is located and contacts the two metal contacts of the second metal sheet group 52, the circuit of the alarm device 3 and the second metal sheet group 52 is conducted, and the alarm device 3 generates an alarm signal. When the sealing piston 4 is extruded to push the extension rod 53 with the two signal contacts 54 to move towards the side where the first metal sheet group 51 is located and contact the two metal contacts of the first metal sheet group 51, the circuit of the alarm device 3 and the first metal sheet group 51 is conducted, and the alarm device 3 generates an alarm signal. The first metal sheet group 51 and the second metal sheet group 52 can be respectively arranged in a manner that the circuit of the alarm device 3 is conducted, so that the helmet can generate an alarm signal through the circuit conduction of the alarm device 3 when it is deformed in any way.

[0057] As shown in Figure 5 The monitoring assembly 5 further includes two first supports 55, a second support 56 and two connecting plates 57, which are all arranged in the monitoring cavity 12. The two first supports 55 are arranged on the side close to the sealing piston 4, and a channel is formed between the two first supports 55 to allow the extension rod 53 to move through. The second support 56 is located on the side away from the sealing piston 4. One of the connecting plates 57 connects the top of the upper first support 55 and the top of the second support 56, and the other connecting plate 57 connects the bottom of the lower first support 55 and the bottom of the second support 56, so that the two first supports 55, the second support 56 and the two connecting plates 57 are connected to form an integral support.

[0058] As shown in Figure 5 The two metal contacts of the first metal sheet group 51 are fixed on the side of the two first supports 55 away from the sealing piston 4, and the two metal contacts of the second metal sheet group 52 are fixed on the side of the second support 56 facing the first support 55, so that the two signal contacts between the first support 55 and the second support 56 can be in contact and electrically connected with the two metal contacts of any metal sheet group when they move.

[0059] As shown in Figure 3As shown, the medium cavity 10 is a special-shaped cavity, including a first cavity 101, a second cavity 102 and a connecting cavity 103, the connecting cavity 103 is communicated with the first cavity 101 and the second cavity 102. Wherein, the first cavity 101 is arranged on the helmet body 1, and the shape thereof is arranged according to the shape of the helmet body 1 itself; the second cavity 102 is arranged on the outside of the helmet body 1 and is arranged in parallel with the first cavity 101. Wherein, in the top view direction, the first cavity 101 can fully cover the entire helmet body 1, and the second cavity 102 is an elongated cavity. Wherein, the sealing piston 4 is movably arranged in the second cavity 102, so as to seal and isolate the two side cavities, one side cavity is used for filling liquid, and the other side cavity is used for placing the monitoring assembly 5. Specifically, the first cavity 101, the connecting cavity 103 and part of the second cavity 102 are sequentially communicated to form a liquid cavity 11, and the remaining part of the second cavity 102 forms a monitoring cavity 12. The medium cavity 10 is arranged as a special-shaped cavity in the above structure, which is more convenient for installation and placement of the monitoring assembly 5, so as to realize real-time monitoring of the helmet. At the same time, the second cavity 102 is arranged as an elongated cavity, so that when the helmet is pressed, the liquid can move to one side of the second cavity 102 in priority, and the deformation of the helmet can be quickly monitored.

[0060] As shown in Figure 1 and Figure 2 , the helmet further comprises a buckling plate 6, which is buckled on the outside of the helmet body 1. The buckling plate 6 has a certain hardness and strength, which can protect the helmet body 1. As shown in Figure 3 , the buckling plate 6 has a certain thickness, which covers the outside of the second cavity 102 and the alarm device 3, and can provide protection for the second cavity 102 and the alarm device 3, while improving the appearance of the helmet. Wherein, the buckling plate 6 is provided with buckles 61, and the helmet body 1 is provided with buckle grooves 13 matched with the buckles 61, and the buckling plate 6 is buckled and connected with the helmet body 1.

[0061] As shown in Figure 1 , the helmet further comprises a brim 7 and a plurality of reinforcing ribs 8. The brim 7 is arranged around the helmet body 1 outside the helmet rim, which improves the strength of the helmet, and also has the functions of shading and rainproof. The plurality of reinforcing ribs 8 are located on the outside of the helmet body 1, and the two ends of the reinforcing rib 8 are connected with the buckling plate 6 and the brim 7 respectively, and the reinforcing rib 8 can further increase the strength of the helmet and play a protective role.

[0062] In this embodiment, the monitoring assembly connected with the alarm device and the liquid sensor are arranged in the helmet, which can monitor whether the helmet is damaged or liquid leaks in real time, so as to timely remind the user to replace the helmet and improve the safety during riding.

[0063] In other embodiments, the monitoring component 5 may not be directly connected to the alarm device 3 via circuit. After the circuit is turned on, the monitoring component 5 can send a circuit-on signal to the control component, which then controls the alarm device 3 to generate an alarm signal based on the circuit-on signal.

[0064] The helmet may also include an adjustment component (not shown in the figure) to adjust the position of the first metal plate group 51 and the second metal plate group 52 within the monitoring cavity 12 by adjusting the overall position of the first bracket 55, the second bracket 56, and the connecting piece 57, thereby improving monitoring accuracy. The positions of the first metal plate group 51 and the second metal plate group 52 can be adjusted based on factors such as temperature difference to further enhance monitoring accuracy. Specifically, a magnetic component is installed on the outer side of the helmet body 1, and magnetism is applied to the overall structure of the first bracket 55, the second bracket 56, and the connecting piece 57. When position adjustment is required, the position of the magnetic component can be externally controlled, causing it to move and adjust the overall structure of the first bracket 55, the second bracket 56, and the connecting piece 57 within the monitoring cavity.

[0065] like Figure 2 and Figure 3 As shown, a flexible contact layer 9 is provided on the inner side of the helmet body 1. The flexible contact layer 9 provides a comfortable wearing experience for users under different climatic conditions. At the same time, the flexible contact layer 9 can also provide a certain impact absorption capacity. The flexible contact layer 9 can be formed of foam materials, memory foam, gel pads, etc. Meanwhile, the medium cavity of the helmet body 1 is filled with liquid, which gives the helmet a certain cushioning and shock absorption effect, bringing a better user experience and meeting the high standards of durability and comfort required for helmets.

[0066] This embodiment installs a liquid sensor inside the helmet body. When the helmet is impacted or damaged, causing liquid leakage in the media cavity, the liquid sensor can quickly detect the lack of liquid in the media cavity. Then, the control component activates the alarm device to generate an alarm signal to alert the user that the helmet is damaged. Simultaneously, a monitoring component is installed inside the helmet body. When the helmet deforms (whether there is no liquid leakage or a leak), the deformed piston pushes the signal contact connected to the extension rod to move and contact the first or second metal plate group, thus activating the circuit connected to the alarm device and causing the alarm device to generate an alarm signal to remind the user. This embodiment automatically alerts the user when the helmet is damaged (deformed or leaking), ensuring that the user does not wear a damaged helmet and greatly improving the safety of riding the vehicle.

[0067] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art.
