[0002] Among the existing safety protection equipment, safety helmets, as an important tool to protect the head from injury, are widely used in high-risk working environments such as construction sites, mining, and traffic maintenance. The design of traditional safety helmets mainly focuses on physical protection, such as using hard materials to make the outer shell and adding a buffer layer inside to absorb impact force, thereby effectively preventing head injuries due to accidents such as collisions and falls.

[0030] Example 1, reference Figure 1 to Figure 10 , which is the first embodiment of the present invention. This embodiment provides a safety helmet that uses Beidou satellite positioning to warn people. The safety helmet that uses Beidou satellite positioning to warn people includes a main assembly 100, including a safety helmet body 101, a placement box 102, a circuit board 103, a power supply rack 104, a battery module 105, a sealing cover plate 106 and a warning light 107.

[0031] The helmet body 101 is made of high-strength material and can withstand various impacts without damage or deformation. The placement box 102 is used to store the circuit board 103 and the battery module 105. The sealing cover 106 is used to seal the placement box 102. The battery module 105 is used to provide a stable power supply for all electronic devices. The circuit board 103 is provided with a processor module, a wireless transceiver module and a Beidou satellite positioning module.

[0032] Processor module: used to receive electrical signals from impact force, process and analyze these signals to determine whether to trigger an alarm, and control the switches of electronic devices such as the warning light 107 and the wireless transceiver module.

[0033] Wireless transceiver module: supports 4G, LoRa, NB-IoT and other wireless communication protocols, and is used to send alarm signals and the wearer's location information to the background management system when an ultra-threshold impact force is detected.

[0034] Beidou satellite positioning module: used to obtain the wearer's precise location information and send it to the background management system.

[0035] The detection component 200 is arranged in the safety helmet body 101, and includes a fixed block 201a fixed to the inner top wall of the safety helmet body 101, a support frame 201b is fixed to the bottom of the fixed block 201a, a support sleeve 201c is fixed in the support frame 201b, a first shaft sleeve 201d is fixed in the support sleeve 201c, a spherical sleeve 201e is fixed at the end of the first shaft sleeve 201d, a second shaft sleeve 201f and a third shaft sleeve 201g are fixed on the surface of the spherical sleeve 201e, and the first shaft sleeve 201d, the second shaft sleeve 201f and the third shaft sleeve 201g are perpendicular to each other.

[0036] The fixing block 201a is used to fix and support the support frame 201b, and the support frame 201b fixes and supports the first sleeve 201d through the support sleeve 201c. The first sleeve 201d, the second sleeve 201f and the third sleeve 201g are perpendicular to each other, so it is convenient to detect the impact force in three-dimensional space. No matter in which direction the wearer is impacted, the safety helmet can sense and respond in time.

[0037] The detection component 200 also includes a detection piece 202 arranged in the first sleeve 201d, the detection piece 202 includes a first spring 202a whose end is fixed to the inner wall of the first sleeve 201d, an impact block 202b is fixed to the end of the first spring 202a, a first insulating rope 202c is fixed to the end of the impact block 202b, a conductive ring 202d is fixed in the spherical sleeve 201e, a first wire 202e is fixed to the other end of the impact block 202b, and the detection piece 202 is arranged in the second sleeve 201f and the third sleeve 201g.

[0038] The first spring 202a is in a stretched state, and the impact block 202b is electrically connected to the first wire 202e. When the helmet is impacted, the impact block 202b can overcome the tension of the first spring 202a, so that the impact block 202b and the conductive ring 202d are in contact, thereby realizing the connection of the electrical signal and sending the impact signal to the processor module.

[0039] A conductive sheet 201h is fixed inside the spherical sleeve 201e, a second wire 201i is fixed to one side of the conductive sheet 201h, a second spring 201j is fixed to the other side of the conductive sheet 201h, an impact ball 201k is fixed to the end of the second spring 201j, and the second spring 201j can be used to electrically connect the impact ball 201k and the conductive sheet 201h.

[0040] The second spring 201j is in a stretched state, and the ends of the three first insulating ropes 202c are fixed on the surface of the impact ball 201k. Through the setting of the conductive sheet 201h and the second spring 201j, the impact ball 201k and the second wire 201i are electrically connected, and the second wire 201i and the three first wires 202e are electrically connected, so that the impact ball 201k and any one of the three impact blocks 202b are in contact with the conductive ring 202d, thereby realizing the connection of electrical signals, thereby sending impact signals to the processor module.

[0041] Specifically, the detection assembly 200 further includes a support member 203 disposed in the helmet body 101 , including a fixed sleeve 203 a fixed to the inner top wall of the helmet body 101 , and a sliding tube 203 b slidingly disposed in the fixed sleeve 203 a .

[0042] A slide groove is provided in the fixed sleeve 203a, and a limit strip is provided on the surface of the sliding tube 203b. The limit strip slides in the slide groove, thereby limiting the position of the sliding tube 203b and the fixed sleeve 203a, so that the sliding tube 203b will not completely slide out of the fixed sleeve 203a.

[0043] Specifically, the support member 203 further includes a perforated plate 203c fixed to the bottom of the sliding tube 203b, and a support block 203d is fixed on the surface of the perforated plate 203c.

[0044] Four sliding tubes 203b are fixed on the top of the orifice plate 203c. The orifice plate 203c contacts the top of the wearer's head. The support block 203d contacts the inner top wall of the helmet body 101, thereby providing position-limiting support for the orifice plate 203c.

[0045] Specifically, the support member 203 further includes a third spring 203e with two ends respectively fixed to the inner top wall of the fixing sleeve 203a and the inner bottom wall of the sliding tube 203b, and a positioning ring 203f is fixed to the surface of the sliding tube 203b.

[0046] The third spring 203e is in a compressed state. Through the reset elastic force of the third spring 203e, the orifice plate 203c can be moved away from the fixing sleeve 203a. When the safety helmet is worn, under the action of the weight of the safety helmet body 101 itself, the fixing sleeve 203a and the sliding tube 203b can continue to compress the third spring 203e, so that the support block 203d contacts the inner top wall of the safety helmet body 101. At this time, the end of the fixing sleeve 203a is located on the side of the positioning ring 203f.

[0047] Specifically, the detection component 200 also includes a conductive member 204, which is arranged on one side of the first sleeve 201d, including a conductive disk 204a fixed to the surface of the first sleeve 201d, a conductive plate 204b fixed to one side of the conductive disk 204a, a conductive column 204c fixed to the other side of the conductive disk 204a, and the conductive plate 204b is fixed to the surface of the conductive ring 202d.

[0048] The conductive disk 204a, the conductive plate 204b and the conductive column 204c are all made of conductive materials. There are three conductive plates 204b, which are electrically connected to the three conductive rings 202d respectively. The conductive column 204c is electrically connected to the circuit board 103. When the impact ball 201k and any one of the three impact blocks 202b contact the conductive ring 202d, the impact force detection mechanism sends out an electrical signal through the conduction of the conductive disk 204a, the conductive plate 204b and the conductive column 204c. The electrical signal is received by the circuit board 103, and is analyzed and processed by the processor module, thereby controlling the warning light 107 to sound an alarm, and the wireless transceiver module sends the alarm signal and the wearer's location information to the background management system.

[0049] Example 2, reference Figure 3 , Figure 6 , Fig. 9 and Fig.10 , which is the second embodiment of the present invention, and this embodiment is based on the previous embodiment.

[0050] Specifically, the detection assembly 200 further includes an isolation member 205, which is disposed on the conductive ring 202d and includes a support column 205a fixed in the conductive ring 202d, and a first insulating rod 205b and a second insulating rod 205c are rotatably connected on the surface of the support column 205a.

[0051] The support column 205a is used to support the first insulating rod 205b and the second insulating rod 205c. The first insulating rod 205b and the second insulating rod 205c are arranged on both sides of the conductive ring 202d. Through the blocking of the first insulating rod 205b and the second insulating rod 205c, the impact ball 201k and the three impact blocks 202b cannot contact the conductive ring 202d, thereby failing to trigger the alarm signal.

[0052] When the first insulating rod 205b and the second insulating rod 205c move away from each other, the impact ball 201k and the three impact blocks 202b may contact the conductive ring 202d.

[0053] Specifically, the isolating member 205 further includes a connecting rod 205d whose end is hinged to the first insulating rod 205b, and another connecting rod 205d is also hinged to the end of the second insulating rod 205c. A pull rod 205e is hinged on the surfaces of the two connecting rods 205d.

[0054] By pulling the pull rod 205e, the pull rod 205e can drive the two connecting rods 205d to move, so that the first insulating rod 205b and the second insulating rod 205c are close to each other. When the pull rod 205e is pushed, the pull rod 205e can push the two connecting rods 205d, so that the first insulating rod 205b and the second insulating rod 205c are away from each other.

[0055] Specifically, the isolation member 205 further includes a connecting block 205f fixed between the two pull rods 205e, a fourth spring 205g is fixed to the inner wall of the connecting block 205f, the other end of the fourth spring 205g is fixed to the inner wall of the conductive plate 204b, and the connecting block 205f slides in the conductive plate 204b.

[0056] The fourth spring 205g is in a stretched state. The restoring tension of the fourth spring 205g enables the connecting block 205f to push the two pull rods 205e, thereby moving the first insulating rod 205b and the second insulating rod 205c away from each other.

[0057] Specifically, the isolation member 205 further includes an insulating sleeve 205h sliding on the surface of the conductive column 204c, and the insulating sleeve 205h and the pull rod 205e are connected by a second insulating rope 205i.

[0058] The insulating sleeve 205h is used to drive the three second insulating ropes 205i to move synchronously, so that the first insulating rods 205b and the second insulating rods 205c on both sides of the three conductive rings 202d are close to each other.

[0059] Specifically, a third insulating rope 205j is fixed to the other end of the insulating sleeve 205h, a support shaft 205k is fixed inside the support frame 201b, a pulley 205l is rotatably connected to the surface of the support shaft 205k, the third insulating rope 205j is located inside the pulley 205l, and the other end of the third insulating rope 205j is fixed to the top of the orifice plate 203c.

[0060] The support shaft 205k is used to support the pulley 205l. When the safety helmet is removed, the orifice plate 203c is moved away from the support frame 201b under the action of the return elastic force of the third spring 203e. At this time, the third insulating rope 205j pulls the insulating sleeve 205h, so that the first insulating rod 205b and the second insulating rod 205c on both sides of the three conductive rings 202d are close to each other, so that the impact ball 201k and the three impact blocks 202b cannot contact the conductive ring 202d, thereby failing to trigger the alarm signal.

[0061] In summary, the present invention has the following beneficial effects: 1. The impact detection mechanism is automatically started when the helmet is put on, and stopped when the helmet is taken off. This function greatly improves the convenience and efficiency of use. Users can start or stop the impact detection without manual operation, reducing the complexity and error rate of manual operation; 2. The helmet can detect impact forces in any direction, which means that no matter which direction the wearer is impacted, the helmet can sense and respond in time. This all-round protection improves the safety of the wearer in various working environments; 3. When an impact force exceeding the preset threshold is detected, the helmet can automatically connect the alarm circuit and send out an alarm signal. This function can send the alarm signal to the background management system, so that relevant personnel can quickly understand the safety status of the wearer and take necessary rescue measures; 4. The application of Beidou satellite positioning technology enables the helmet to accurately provide the wearer's location information. In an emergency, this function is crucial for quickly locating and finding the wearer, helping to shorten rescue time and improve rescue efficiency. During use, when the safety helmet is worn, the orifice plate 203c is pressed toward the support frame 201b. At this time, under the reset tension of the fourth spring 205g, the connecting block 205f can push the two pull rods 205e, so that the first insulating rod 205b and the second insulating rod 205c are moved away from each other, and the impact ball 201k and the three impact blocks 202b can contact the conductive ring 202d. When the wearer of the safety helmet is subjected to an impact exceeding the threshold, the impact ball 201k or the impact block 202b can contact the conductive ring 202d, so that the circuit can send an impact signal to the processor module. Through analysis and processing by the processor module, the warning light 107 is controlled to sound an alarm, and the wireless transceiver module sends the alarm signal and the wearer's location information to the background management system, so that relevant personnel can quickly understand the wearer's safety status and take necessary rescue measures.

[0062] When the safety helmet is taken off, under the action of the restoring elastic force of the third spring 203e, the orifice plate 203c is moved away from the support frame 201b. At this time, the third insulating rope 205j pulls the insulating sleeve 205h, so that the insulating sleeve 205h pulls the pull rod 205e through the second insulating rope 205i, and the pull rod 205e can drive the two connecting rods 205d to move, so that the first insulating rod 205b and the second insulating rod 205c are close to each other. Through the obstruction of the first insulating rod 205b and the second insulating rod 205c, the impact ball 201k and the three impact blocks 202b cannot contact the conductive ring 202d, thereby failing to trigger the alarm signal, thereby preventing the alarm signal from being accidentally triggered when the safety helmet is not worn.

[0063] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present invention, which should all be included in the scope of the claims of the present invention.
