Examples

[0020] Combining FIGS. 1-5, the present embodiment provides a helmet with a smart chin strap including a helmet body 3 and chin straps 1 arranged on both sides of the helmet body 3. The two chin straps 1 are connected by a locking member 2. The locking member 2 is unlocked by a trigger from a control terminal. The control terminal can monitor the state of the locking member 2. The state at least includes an unlocked state and a locked state. When the wearer locks the locking member 2, the two chin straps 1 are in close contact with the human face, and synchronously, the control terminal displays that it is in the locked state. Also, when the wearer triggers the locking member 2 in an operable manner and sends an "unlock" signal to the control terminal, the administrator located at the control terminal can choose to approve or reject the "unlock" request, thereby unlocking the locking member 2 appropriately or maintaining the locked state continuously.

[0021] Exemplarily, the connection position between the chin strap 1 and the helmet body 3 is provided inside the helmet body 3. Thereby, the connection position cannot be seen from the outside of the helmet body 3, preventing the situation where the wearer (i.e., the construction worker) removes the chin strap 1 from the connection position. The locking member 2 and the control terminal perform remote unlocking using WiFi or Bluetooth (registered trademark) technology. Preferably, the chin strap 1 is designed to be in close contact with the face and its length cannot be adjusted. The chin strap 1 has three fixed lengths: long, medium, and short, and the wearer can choose and wear any length according to their face shape. By fixing the length of the chin strap 1, the situation where the worker takes off the helmet without permission is avoided. In one embodiment, the chin strap 1 adopts a cut prevention design including an inner layer and an outer layer. The outer layer is provided to wrap the inner layer. The inner layer uses a metal material, and the outer layer uses a plastic material. For example, a steel elastic piece is used for the inner layer of the chin strap 1. Then, by molding the outer layer by overmolding or two-shot molding, it is ensured that the outer layer does not damage the human face.

[0022] It should be noted that in this embodiment, when a wearer wants to remove the helmet, he or she simply presses the button 211 on the locking member 2 or sends an "unlock" request to the control terminal using other trigger methods. If the "unlock" request is agreed to by the administrator, the locking member 2 is unlocked synchronously. This is convenient for the wearer to remove the helmet in a safe environment. In this case, the locking member 2 can be unlocked only when the administrator's control terminal (e.g., a mobile phone) agrees to the "unlock" request, thereby preventing the wearer from removing the helmet without permission. In addition, the control terminal can monitor the state of the locking member 2. This is convenient for the administrator to supervise the wearer's wearing status and saves time for manual inspections.

[0023] In a preferred embodiment, the locking member 2 includes a first locking portion 21 and a second locking portion 22. The two locking portions are respectively connected to the chin strap 1. When the wearer engages the first locking portion 21 and the second locking portion 22, the control terminal displays a message indicating that the helmet is locked. For example, the first locking portion 21 and the second locking portion 22 are L-shaped. However, in other embodiments, they may be configured with a T-shaped groove, pin, or other structure. When the wearer engages the two L-shaped portions, the wireless transceiver module located in the first locking portion 21 transmits a wireless signal. The control terminal (a mobile phone app) receives the wireless signal and records the lock time. Synchronously, the app's status column displays a message indicating that the helmet is locked. When the wearer wants to remove the helmet, they press the button 211 on the first locking portion 21, triggering the wireless transceiver module to send an "unlock" request to the control terminal. If the administrator agrees to the "unlock" request, the administrator sends an unlock command. The wireless transceiver module receives the unlock command and unlocks the helmet. The circuit principle for locking and unlocking the first locking unit 21 and the second locking unit 22 is a conventional technique and will not be described in detail here. Alternatively, the control method for an insert-type helmet buckle device disclosed in Chinese Utility Model No. 217487767 can be referred to.

[0024] Preferably, each locking member 2 has a unique serial number. Since the serial number corresponds to one wearer, it is convenient for the administrator to manage it appropriately. The administrator can add the name to the mobile phone app and associate the serial number with the wearer one-to-one. For example, associate serial numbers 001, 002, and 003 with Zhang San, Li Si, and Wang Wu respectively. However, it is not limited to this, and specifically it is not limited. As a point to mention, when the WiFi of any locking member 2 is slightly weak, the corresponding serial number will be slowly blinking and displayed on the app. In this case, in order to ensure the safety of the wearer, the locking member 2 will remain in the locked state. Also, the administrator may notify the wearer to return to the management base for inspection and repair of the locking member 2.

[0025] In another embodiment, a front camera 23 is provided on the locking member 2. The front camera 23 is configured so that its lens faces the outside of the human body and is configured to take a photo synchronously with the transmission of the "unlock" request from the locking member 2 and transmit the photo to the control terminal. In another embodiment, a rear camera may also be provided on the locking member 2, with the lens facing the inside of the human body. The two cameras may be configured to take photos at predetermined times and transmit the photos to the control terminal. The administrator can determine the wearer's environment based on the transmitted photos and ensure that the wearer is in a safe environment before agreeing to the "unlock" request. Furthermore, if the image angle transmitted to the mobile phone does not change for a long period of time or remains the same for a long period of time, this may indicate that the helmet has been left nearby and is not being worn by the worker. Therefore, the photo transmitted from the rear camera may further determine whether the helmet is being worn properly. If the helmet is being worn properly, the rear camera should capture a photo of the wearer's throat or neck every time. In addition, the wearing status of the helmet at the construction site can be monitored from the shooting angle of another wearer, so that the effect of mutually assisting each other in supervision can be achieved. Note that the circuit principle between the camera and the control terminal is conventional technology, so it will not be described in detail here.

[0026] In one embodiment, the control terminal is configured to display the unlock time and expiration date of the locking member 2. The length of time the worker wears the device can be obtained from the unlock time, and this time can be considered as attendance time and used in the attendance record. The control terminal also has the function of combining the daily lock time and unlock time to create a daily report. This is convenient for managers to check the daily wearing status. Furthermore, when the expiration date of any of the locking members 2 has passed, the column for that locking member 2 flashes, prompting the manager to replace, inspect, or repair it. Furthermore, if the chin strap 1 breaks or tears, the locking member 2 immediately notifies the manager by sending a related signal to the app. For example, a sensor is installed between the chin strap 1 and the locking member 2. If the chin strap breaks, the tensile force of the chin strap will be significantly smaller than under normal conditions, and the sensor will transmit a signal to the wireless transceiver module, which then transmits the signal to the control terminal. However, this is not limited to this.

[0027] In another embodiment, the locking member 2 is provided with a charging port and an electric charge indicator 212. The control terminal can also display the charging status of the locking member 2. The wearer or the manager can charge the locking member 2 when the electric charge of the locking member 2 becomes low. The wearer may also be required to charge the locking member 2 at the end of work each day. The manager can monitor whether the wearer is charging the locking member 2 every day by checking the status display of the electric charge mark on the control terminal.

[0028] Based on the above embodiment, in an alternative embodiment of the present invention, the locking member 2 includes a mechanical lock 24. The locking member 2 is configured to be unlocked by the mechanical lock 24. The mechanical lock 24 is located at the bottom of the locking member 2. An openable protective cover is located corresponding to the position of the mechanical lock 24. For example, the mechanical lock 24 is located at the bottom of the second locking portion 22. A T-shaped slide groove is provided at the bottom. The edge of the protective cover fits into the T-shaped slide groove so that the protective cover can be removed along the T-shaped slide groove. Alternatively, one end of the protective cover is hingedly connected to the second locking portion 22, and the other end is connected to the second locking portion 22 by a hook. However, this is not limited to this example and is not specifically limited. If the locking member 2 runs out of power and is unable to operate normally, the locking member 2 can be charged using a portable power source. If the locking member 2 is damaged, a call to the administrator may be made, and the administrator may notify the wearer of the mechanical PIN. The wearer can open the protective cover of the locking member 2 and view the button of the mechanical lock 24 on the locking member 2 using a mirror or a mobile phone camera. Then, the wearer can unlock the locking member 2 by entering the PIN number obtained from the administrator. This prevents workers from having to use tools such as pliers or cutters in an emergency, reducing the chance of injury. For example, the first locking portion 21 is provided with a locking hole, and the second locking portion 22 is provided with a deadbolt. The deadbolt can be moved using a driving device in response to a command from a control terminal, or by the mechanical lock 24, thereby realizing two types of unlocking methods, but the present invention is not limited to these.

[0029] The method of use of this embodiment is as follows.

[0030] 1. Before entering the site and starting work, the operator connects the first locking part 21 and the second locking part 22. Then, it is automatically displayed on the app of the administrator's mobile phone that it is in a locked state, and the locking time is recorded. Since the operator cannot remove the helmet by himself until the lock is released, the safety during construction is guaranteed.

[0031] 2. When the operator wants to take off the helmet, first, he needs to leave the site area and press the button 211 of the locking member 2. Then, at the same time, a photo of the site is immediately taken by the camera of the locking member 2 and sent to the app of the administrator's mobile phone together with the "unlock" request signal. When the app of the administrator's mobile phone receives the "unlock" request, it determines whether the operator has left the site area based on the photo transmitted at the same time. By selecting whether to agree or reject the request, it is ensured that the operator takes off the helmet in a safe environment. When the locking member 2 receives the unlock command transmitted from the app, it is immediately unlocked. As a result, the operator can remove the helmet.

[0032] It should be noted that when the operator wants to take off the helmet but it is difficult to leave the site, for example, when in a relatively safe location such as a conference room or an office building, he needs to search for a relatively safe location and then send an "unlock" request.

[0033] The above is only a preferred embodiment of the present invention, and the protection scope of the present invention is not limited to the above embodiments. Any technical solutions belonging to the concept of the present invention belong to the protection scope of the present invention.
