Description

[Technical Field]

[0001] The present invention relates to the technical field of helmets, and in particular to helmets with smart chin straps. [Background technology]

[0002] Safe production is the goal of every construction company, and wearing helmets correctly is the first step to achieving safe production. Therefore, helmet inspections have become a mandatory daily inspection for construction companies. However, due to differences in the nature of personnel, the importance of safe production is not fully understood, and they are unable to effectively follow the instructions of their superiors. Some workers do not understand the importance of helmet protection, and often work without their helmets, without following the work regulations for safe production, which leads to occasional accidents caused by not wearing helmets. Summary of the Invention [Problem to be solved by the invention]

[0003] The present invention discloses a helmet with a smart chin strap that can avoid the problem of workers removing their hats without permission by monitoring the wearing status of the helmet. [Means for solving the problem]

[0004] The present invention adopts the following solution.

[0005] A helmet with a smart chin strap includes a helmet body and chin straps disposed on both sides of the helmet body. The two chin straps are connected by a locking member. The locking member is unlocked by a trigger from a control terminal. The control terminal can monitor the state of the locking member, which includes at least an unlocked state and a locked state. When a wearer locks the locking member, the chin strap fits tightly against the face of the wearer, and the control terminal simultaneously indicates that the chin strap is in the locked state. When the wearer triggers the locking member in an operable manner and sends an "unlock" signal to the control terminal, an administrator located at the control terminal can choose to accept or reject the "unlock" request, thereby unlocking the locking member accordingly or maintaining it in the locked state.

[0006] Preferably, the locking member includes a first locking portion and a second locking portion, the two locking portions being connected to a chin strap, and when the wearer engages the first locking portion with the second locking portion, the control terminal displays a message indicating that the device is locked.

[0007] Preferably, the locking member includes a mechanical lock, and the locking member is configured so that unlocking can be achieved by the mechanical lock.

[0008] Preferably, the mechanical lock is disposed at the bottom of the locking member, and an openable and closable protective cover is disposed in correspondence with the position of the mechanical lock.

[0009] Preferably, the locking member is provided with a front camera, the front camera being arranged with a lens facing the outside of the human body, and configured to take a photograph in synchronization with the transmission of the "unlock" request by the locking member and transmit the photograph to the control terminal.

[0010] Preferably, a rear camera is disposed on the locking member, and the lens of the rear camera faces the inside of the human body.

[0011] Preferably, the camera is configured to take a photograph at a predetermined time and transmit the photograph to the control terminal.

[0012] Preferably, the chin strap includes an inner layer and an outer layer, the outer layer being disposed to enclose the inner layer, the inner layer being made of a metal material, and the outer layer being made of a plastic material.

[0013] Preferably, the control terminal is configured to be able to display the unlocking time and expiration date of the locking member.

[0014] Preferably, the locking member is provided with a charging port and a power indicator, and the control terminal is capable of displaying the charging status of the locking member. [Effects of the Invention]

[0015] By adopting the above technical solution, the present invention can achieve the following technical effects:

[0016] With the helmet with a smart chin strap of the present application, when a wearer wants to remove the helmet, they simply press the button on the locking member or send an "unlock" request to the control terminal using some other trigger method. If the administrator agrees to the "unlock" request, the locking member is unlocked synchronously. This allows the wearer to remove the helmet in a safe environment. In this case, the locking member can be unlocked only when the administrator's control terminal (e.g., a mobile phone) agrees to the "unlock" request, preventing the wearer from removing the helmet without permission and ensuring safety during installation. The control terminal can also monitor the status of the locking member. This allows the administrator to easily monitor the wearer's wearing status and saves time on manual inspections.

[0019] In order to make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the following clearly and concisely describes the technical solutions in the embodiments of the present invention in combination with the drawings relating to the embodiments of the present invention. It goes without saying that the described embodiments are only some embodiments of the present invention, and not all embodiments. All other embodiments that can be obtained by those skilled in the art based on the embodiments of the present invention without the need for creative work are also within the scope of protection of the present invention. Therefore, the following detailed description of the embodiments of the present invention provided in the drawings is not intended to limit the scope of the claimed invention, but merely illustrates selective embodiments of the present invention. All other embodiments that can be obtained by those skilled in the art based on the embodiments of the present invention without the need for creative work are also within the scope of protection of the present invention. [Example]

[0020] Combining Figures 1 to 5, this embodiment provides a helmet with a smart chin strap, which includes a helmet main body 3 and chin straps 1 arranged on both sides of the helmet main 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, which includes at least an unlocked state and a locked state. When the wearer locks the locking member 2, the two chin straps 1 fit tightly against the face of the wearer, and the control terminal displays a locked state in synchronization with this. In addition, when the wearer triggers the locking member 2 in an operable manner and sends an "unlock" signal to the control terminal, an administrator located at the control terminal can choose to agree or reject the "unlock" request, thereby appropriately unlocking the locking member 2 or maintaining it in the locked state.

[0021] For example, the connection point between the chin strap 1 and the helmet body 3 is located inside the helmet body 3. This makes the connection point invisible from the outside of the helmet body 3, preventing the wearer (i.e., a construction worker) from removing the chin strap 1 from the connection point. The locking member 2 and the control terminal use Wi-Fi or Bluetooth® technology for remote unlocking. Preferably, the chin strap 1 is designed to fit snugly against the face and its length is not adjustable. The chin strap 1 comes in three fixed lengths: long, medium, and short. The wearer can choose one of these lengths according to their face shape. Fixing the length of the chin strap 1 prevents workers from removing the hat without permission. In one embodiment, the chin strap 1 has a cut-resistant design including an inner layer and an outer layer. The outer layer is configured to encase the inner layer. The inner layer is made of a metal material, and the outer layer is made of a plastic material. For example, the inner layer of the chin strap 1 is made of a steel elastic piece. The outer layer is formed by overmolding or two-shot molding to ensure that the outer layer does not injure the face of the human body.

[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 element 2 has a unique serial number. Since each serial number corresponds to a single wearer, it is convenient for the administrator to manage them appropriately. The administrator can add names to a mobile phone app to associate serial numbers with wearers one-to-one. For example, serial numbers 001, 002, and 003 could be associated with Zhang San, Li Si, and Wang Wu, respectively. However, this is not a specific example. It should be noted that if the Wi-Fi connection of any locking element 2 is weak, the app will display the corresponding serial number slowly flashing. In this case, the locking element 2 will remain locked to ensure the wearer's safety. The administrator may also notify the wearer to return to the management location for inspection and repair of the locking element 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 worker connects the first locking unit 21 and the second locking unit 22. The app on the supervisor's mobile phone automatically displays a message that the helmet is locked, and the locking time is recorded. The worker cannot remove the helmet by himself until the next time the lock is released, ensuring safety during construction.

[0031] 2. If a worker wants to take off his / her hat, he / she must first leave the work site and press the button 211 on the locking member 2. At the same time, a photo of the work site is immediately taken by the camera on the locking member 2 and sent to the app on the manager's mobile phone along with an "unlock" request signal. When the app on the manager's mobile phone receives the "unlock" request, it determines whether the worker has left the work site based on the photo sent at the same time. This allows the worker to choose whether to accept or reject the request, ensuring that the worker takes off his / her hat in a safe environment. When the locking member 2 receives the unlock command sent from the app, it is immediately unlocked. This allows the worker to take off his / her helmet.

[0032] It should be noted that if a worker wishes to remove their helmet but is uncomfortable leaving the work site, they should seek out a relatively safe location, such as a conference room or office building, before sending an "unlock" request.

[0033] The above are only preferred embodiments of the present invention, and the scope of protection of the present invention is not limited to the above examples. Any technical solutions that fall within the concept of the present invention are also within the scope of protection of the present invention. [Explanation of symbols]
