Description

Technical Field

[0001] The present application relates to the field of helmets, and in particular to a helmet with a function of detecting correct wearing. Background Art

[0002] With shared electric bikes becoming an increasingly popular mode of transportation, wearing a helmet correctly is crucial. However, some people don't wear helmets or wear them improperly during riding, which can lead to safety risks and accidents.

[0003] Existing motorcycle helmets often lack a function to detect whether the helmet is worn correctly, making it impossible for the motorcycle's control unit to determine whether the user is wearing the helmet correctly. Furthermore, in some shared motorcycles, the lack of cleanliness of helmets makes users even more reluctant to wear them, increasing safety risks. Furthermore, while some existing helmets have a function to detect whether the helmet is worn correctly, the accuracy of the detection method is often low. Sometimes, a user inserts the helmet buckle but does not wear it correctly. In this case, it is often impossible to detect, resulting in problems with the detection accuracy. Utility Model Content

[0004] Purpose of the utility model: This application overcomes the defects of the prior art and provides a helmet with a function of detecting correct wearing.

[0005] Technical solution: A helmet includes a helmet body, a first buckle, a connecting strap and a buckle, the buckle is connected to the connecting strap, a Hall sensor is installed at the first buckle, the buckle has a magnetic block, and the buckle can be inserted into the first buckle.

[0006] Furthermore, the first buckle portion has a slot, and both sides of the slot have limiting side through holes that cooperate with the buckle. The buckle includes a main body and two limiting units connected to the main body. The limiting units include a limiting block that cooperates with the limiting side through holes and a connecting rod connecting the limiting block and the main body.

[0007] Thus, the insert buckle and the first buckle portion can be better fixedly connected.

[0008] Furthermore, the first buckle portion has a mounting cavity and a through-hole portion communicating with the mounting cavity, a closing cover is installed at the through-hole portion, and the Hall sensor is installed in the mounting cavity.

[0009] This provides installation space for the Hall sensor and makes it easy to open the closing cover for inspection or replacement.

[0010] Furthermore, the end of the slot also has a blind hole portion, and the buckle also includes a fixing rod fixedly connected to the main body portion, and the end of the fixing rod is equipped with the magnetic block, and the magnetic block can be inserted into the blind hole portion.

[0011] The magnetic block extends into the blind hole portion, so that the distance between the Hall sensor and the magnetic block is closer, and the Hall sensor can better cooperate with the magnetic block for detection.

[0012] Furthermore, the closing cover is threadedly connected to the through hole portion, the closing cover is provided with a sealing ring, the closing cover is also provided with a bar block, and the bar block is provided with a bar groove; the magnetic block is connected to the mounting block, the mounting block is connected to the stud, and the end of the fixing column has a threaded hole that cooperates with the stud.

[0013] Thereby, the installation and replacement of the magnetic block are facilitated.

[0014] Furthermore, it also includes a second buckle, the first buckle and the second buckle are both fixed buckles, which are respectively fixed on both sides of the helmet body; the second buckle is also hinged with a rotating buckle, and the rotating buckle is connected to one end of the connecting belt; the rotating buckle has a pressure block, and the second buckle is installed with a pressure sensor, and the pressure sensor can be pressed by the pressure block.

[0015] Furthermore, the second buckle portion has a mounting groove, a pressure sensor is installed in the mounting groove, and the mounting groove is also provided with a rubber sheet for closing the mounting groove, and the pressure block can abut against the rubber sheet to press the pressure sensor.

[0016] This protects the pressure sensor from moisture.

[0017] Furthermore, the main bodies of the rotating buckle and the inserting buckle both have strip-shaped through holes that cooperate with the connecting belt.

[0018] Thereby making it easy to connect with the connecting belt.

[0019] Furthermore, the connecting belt has a Japanese-shaped buckle.

[0020] Thereby making it easy to adjust according to the size of different people's heads.

[0021] Furthermore, the helmet is also connected to a connecting cable, wherein the connecting cable has a first wire connected to the Hall sensor and a second wire connected to the pressure sensor.

[0022] This makes it easier to connect the helmet to the electric bicycle and transmit signals to the Hall sensor and pressure sensor.

[0023] Furthermore, the end of the connecting cable is connected to the second buckle portion.

[0024] In other embodiments, a control unit, a battery and a Bluetooth unit are further included, and the Hall sensor, the pressure sensor and the Bluetooth unit are all connected to the control unit.

[0025] There is no need for connecting cables, it is powered by batteries and transmits signals via Bluetooth.

[0026] Beneficial effects: 1) The helmet of the present application is suitable for shared electric motorcycles and can also be used for household electric motorcycles, with a wide range of applications.

[0027] 2) The detection of the present application can achieve relatively accurate detection of whether the helmet is worn correctly through the detection of the Hall sensor and the pressure sensor.

[0028] 3) The present application provides better protection for the Hall sensor and pressure sensor, and some components are more convenient to inspect and repair. BRIEF DESCRIPTION OF THE DRAWINGS

[0042] Example 1:

[0043] like Figure 1-4 The figure shows a helmet with a function for detecting whether a helmet is worn correctly, comprising a helmet body 1, a first buckle 1.1, a connecting strap 2, and a buckle 4. The buckle 4 is connected to the connecting strap 2. A Hall sensor 1.1.3 is mounted on the first buckle 1.1. The buckle 4 has a magnetic block 4.7, and the buckle 4 can be inserted into the first buckle 1.1. The first buckle 1.1 has a slot 1.1.6, and two sides of the slot 1.1.6 have limiter side through holes 1.1.7 that cooperate with the buckle 4. The buckle 4 includes a main body 4.1 and two limit units connected to the main body 4.1. The limit units include a limit block 4.3 that cooperates with the limiter side through holes 1.1.7 and a connecting rod 4.2 connecting the limit block 4.3 and the main body 4.1. The first buckle portion 1.1 has an installation cavity 1.1.2 and a through hole portion 1.1.1 connected to the installation cavity 1.1.2, and a closing cover 1.1.4 is installed at the through hole portion 1.1.1, and the Hall sensor 1.1.3 is installed in the installation cavity 1.1.2; the end of the slot 1.1.6 also has a blind hole portion 1.1.8, and the buckle 4 also includes a fixing rod 4.4 fixedly connected to the main body portion 4.1, and the end of the fixing rod 4.4 is installed with the magnetic block 4.7, and the magnetic block 4.7 can be inserted into the blind hole portion 1.1.8. The closing cover 1.1.4 is threadedly connected to the through-hole portion 1.1.1, and a sealing ring is provided at the closing cover 1.1.4. The closing cover 1.1.4 also has a strip block 1.1.5, and the strip block 1.1.5 has a strip groove; the magnetic block 4.7 is connected to the mounting block 4.6, and the mounting block 4.6 is connected to the stud 4.5. The end of the fixing column 4.4 has a threaded hole that cooperates with the stud 4.5.

[0044] The helmet of the present application also includes a second buckle 1.2. Both the first buckle 1.1 and the second buckle 1.2 are fixed buckles, respectively fixed to either side of the helmet body 1. A pivoting buckle 5 is hingedly connected to the second buckle 1.2, which is connected to one end of the connecting strap 2. A pressure block 5.1 is provided on the pivoting buckle 5. A pressure sensor is mounted on the second buckle 1.2, which can be pressed by the pressure block 5.1. The second buckle 1.2 has a mounting slot, in which the pressure sensor is mounted. The mounting slot also has a rubber sheet 1.2.1 that seals the mounting slot. The pressure block 5.1 can abut against the rubber sheet 1.2.1, thereby pressing the pressure sensor. The main bodies of the pivoting buckle 5 and the plug buckle 4 each have a strip-shaped through hole that mates with the connecting strap 2. The connecting strap 2 has a Japanese buckle 2.1. The second buckle of the helmet is connected to a connecting cable 3, which contains a first wire connected to the Hall effect sensor and a second wire connected to the pressure sensor.

[0045] When the user wears the helmet correctly, the buckle inserts into the slot of the first buckle section, allowing the Hall effect sensor to sense the magnet and determine whether the buckle is inserted into the slot of the first buckle section. However, sometimes people insert the buckle into the slot of the first buckle section, but the connecting strap does not actually pass through the chin. Instead, it is located at the back of the head or placed in the bicycle basket. Therefore, although the Hall effect sensor detects a signal, the helmet is not actually worn correctly. Therefore, this application also uses a pressure sensor to detect. Only when the connecting strap is located at the chin and the tightness of the connecting strap is appropriate, the pressure block of the rotating buckle will press the pressure sensor (when the connecting strap is located at the back of the head or the helmet is placed in the bicycle basket, the pressure sensor cannot be guaranteed to be pressed at all times). Only when the Hall effect sensor and the pressure sensor detect signals at the same time can the helmet be determined to be worn correctly.

[0046] The helmet and the vehicle it is used in can be flexibly coordinated. For example, the program can be set so that the prompt sound of the electric bicycle will be eliminated only when the helmet is worn correctly. Otherwise, the prompt "wear helmet correctly" will continue to be given, thereby ensuring that people wear helmets correctly.

[0047] Example 2

[0048] The difference between Example 2 and Example 1 is that the helmet of Example 2 has no connecting cable. The helmet of Example 2 includes a control unit, a battery and a Bluetooth unit, and the Hall sensor, pressure sensor and Bluetooth unit are all connected to the control unit.

[0049] The helmet of Example 2 does not need to be connected to the electric vehicle via a connecting cable, but communicates with the control unit of the electric vehicle via a Bluetooth unit, so that the helmet of Example 2 has better flexibility.

[0050] Although the present invention has been illustrated and described with respect to preferred embodiments, it will be understood by those skilled in the art that various changes and modifications may be made to the present invention without departing from the scope of the present invention as defined by the claims.
