[0002] With the development of science and technology, more and more head-mounted devices are being used in industrial or commercial systems, such as head-mounted flashlights and head-mounted thermal imagers. These head-mounted devices are primarily powered by their built-in batteries. Currently, power-on and power-off operations on head-mounted devices are usually achieved through buttons on the device's surface. However, this requires openings in the surface, which increases the likelihood of moisture entering the device, thus increasing the probability of damage caused by moisture penetration. Utility Model Content

[0008] Furthermore, the wireless charging module includes a charging coil and a power management module. The charging coil is disposed inside the housing, and the power management module is disposed on the motherboard and is electrically connected to both the charging coil and the power supply.

[0009] Furthermore, the functional component is an illumination component or a thermal imager.

[0010] Furthermore, the housing has an interconnected battery compartment and mounting cavity inside, the power supply is located in the battery compartment, and the motherboard and the functional components are located in the mounting cavity.

[0011] Furthermore, it also includes a conductive ring, a connecting metal plate, and a connecting wire.

One end of the connecting wire is electrically connected to the other of the positive and negative terminals of the power supply, and the other end is electrically connected to the control module.

[0012] Furthermore, one end of the battery compartment has an opening that communicates with the outside; the head-mounted device also includes a sealing cover, which is detachably connected to the housing and can seal the opening when connected to the housing.

[0013] Furthermore, a conductive structure is provided on the inner side of the sealing cap; When the sealing cap is connected to the housing, the conductive structure abuts against the conductive ring and is electrically connected to one of the positive and negative terminals of the power supply.

[0014] Furthermore, the sealing cap is threaded to the housing, and the head-mounted device also includes a sealing ring. When the sealing cap is connected to the housing, the sealing ring is clamped between the sealing cap and the housing.

[0015] In summary, the head-mounted device provided in this application has at least the following advantages: 1.

[0025] like Figure 1 and Figure 2 As shown, this application provides a head-mounted device, including a housing 11, a motherboard 12, a power supply 13, a control module 14, a gyroscope module 15, and functional components.

[0026] Functional components are housed in the housing 11 and are used to realize the functions of the head-mounted device, including but not limited to providing illumination. The mainboard 12 and power supply 13 are both located within the housing 11, while the control module 14 and gyroscope module 15 are both located on the mainboard 12. The control module 14 is electrically connected to the power supply 13, the gyroscope module 15, and the functional components. The gyroscope module 15 can detect the attitude information of the housing 11, and the control module 14 can acquire the attitude information and control the power supply 13 to supply power to the functional components based on the attitude information. Optionally, the functional components can be illumination components, such as LED lights, or thermal imagers; no limitation is made here.

[0027] Using the aforementioned head-mounted device, the housing 11 can assume various postures during use. The gyroscope module 15 can detect these postures, and the control module 14, after acquiring the posture information, can control the power supply 13 to supply power to the functional components or to cut off power to the power supply 13 based on the posture information. This eliminates the need for openings on the surface of the housing 11 to install buttons, preventing external water from entering the housing 11 through button mounting holes, thus reducing the probability of moisture entering the interior and causing damage to the device, and extending the device's service life.

[0028] In one embodiment, the head-mounted device further includes a head-mounted component for stably wearing the device on the user's head. A housing 11 is rotatably mounted on the head-mounted component and has both a horizontal and a vertical orientation during rotation. When the housing 11 rotates to a horizontal orientation, the control module 14 controls the power supply 13 to supply power to the functional components; when the housing 11 rotates to a vertical orientation, the control module 14 controls the power supply 13 to de-energize.

[0029] It should be noted that, taking the lighting component as an example, under normal use: when the housing 11 rotates to a horizontal position, the lighting component faces the user's front, meaning the light emitted by the lighting component shines in front of the user; when the housing 11 rotates to a vertical position, i.e., the housing 11 is flipped upwards, the lighting component faces the user's upper position, and at this time the lighting component is de-energized. Of course, in other embodiments, the housing 11 may also include other positions. The control module 14 can control the power supply of the power supply 13 according to the corresponding position. It is only necessary to calibrate the position and set the corresponding control action of the control module 14. This operation is a conventional method and will not be described in detail here.

[0030] Furthermore, the housing 11 is rotatably connected to the head-mounted component, forming a pivot on the outside of the housing 11, and a bearing corresponding to the pivot is mounted on the head-mounted component. Simultaneously, a damping structure, such as a rubber layer, can be provided on the housing 11 and the head-mounted component to increase the damping of the housing 11's rotation and prevent the housing 11 from wobbling during use; alternatively, structures that can engage with each other, such as locking parts, can be provided on the housing 11 and the head-mounted component. When the housing 11 rotates to a horizontal or vertical position, the locking parts on the housing 11 can engage with the locking parts on the head-mounted component, similarly preventing the housing 11 from wobbling during use.

[0031] In one embodiment, the housing 11 has an interconnected battery compartment and a mounting cavity. The power supply 13 is located in the battery compartment, and the mainboard 12 and functional components are located in the mounting cavity. Further, the head-mounted device also includes a conductive ring 16, a connecting metal plate 17, and a connecting wire 18. The conductive ring 16 is located in the battery compartment and is electrically connected to one of the positive and negative terminals of the power supply 13. The connecting metal plate 17 is electrically connected to the control module 14 via the mainboard 12, with one end of the connecting metal plate 17 away from the mainboard 12 abutting against the conductive ring 16. One end of the connecting wire 18 is electrically connected to the other of the positive and negative terminals of the power supply 13, and the other end is electrically connected to the control module 14, thereby electrically connecting the power supply 13 and the control module 14. Specifically, the connecting wire 18 is electrically connected to the negative terminal of the power supply 13 via a metal spring and a metal plate, and the conductive ring 16 is electrically connected to the positive terminal of the power supply 13.

[0032] In Embodiment 1, the head-mounted device also includes a wireless charging module, which is disposed inside the housing 11 and electrically connected to the power source 13 to enable wireless charging of the power source 13. This eliminates the need for openings on the surface of the housing 11 for battery insertion and removal, further improving the sealing performance of the housing 11. It is certain that the power source 13 is a rechargeable battery, such as a rechargeable lithium battery.

[0033] Furthermore, the wireless charging module includes a charging coil and a power management module 13. The charging coil is housed within the housing 11, and the power management module 13 is located on the main board 12 and is electrically connected to both the charging coil and the power supply 13, enabling the power supply 13 to be charged via the charging coil. It should be noted that the charging principle of the charging coil is conventional technology and will not be elaborated upon here. It should also be noted that the power management module 13 can also be integrated into the control module 14; this is not a limitation.

[0034] In embodiment 2, one end of the battery compartment has an opening that communicates with the outside, allowing the power source 13 inside the battery compartment to be accessed and removed through the opening. The head-mounted device also includes a sealing cover 19, which is detachably connected to the housing 11 and can seal the opening when connected to the housing 11.

[0035] Furthermore, the sealing cap 19 is threaded to the housing 11, and the head-mounted device also includes a sealing ring 20. When the sealing cap 19 is connected to the housing 11, the sealing ring 20 is clamped between the sealing cap 19 and the housing 11, thereby sealing the space between the sealing cap 19 and the housing 11 and reducing the probability of external moisture entering.

[0036] It should also be noted that in Embodiment 2, a conductive structure is provided on the inner side of the sealing cap 19. When the sealing cap 19 is connected to the housing 11, the conductive structure abuts against the conductive ring 16 and is electrically connected to one of the positive and negative terminals of the power supply 13. Similarly, the conductive structure is electrically connected to the positive terminal of the power supply 13.

[0037] It should be noted that, in conjunction with Embodiments 1 and 2, Embodiment 1 has the advantage of higher sealing performance compared to Embodiment 2; Embodiment 2 has the advantage of replaceable power supply 13, which can directly use dry cell batteries, potentially resulting in lower short-term operating costs. Furthermore, Embodiment 2 is unaffected by situations where charging is inconvenient. Of course, in this application, Embodiment 1 is preferred in order to improve the device's sealing performance, reduce the probability of external moisture ingress, and extend the device's lifespan.

[0038] In addition, it should be further explained that by setting the gyroscope module 15 in this application, the number of button mounting holes on the housing 11 is reduced, which to a certain extent improves the sealing performance of the housing 11 and reduces the probability of external moisture entering the interior of the housing 11.

[0039] In one embodiment, the head-mounted device further includes a wireless module, which is located on the motherboard 12 and electrically connected to the control module 14, thereby enabling wireless control of the head-mounted device. Taking the lighting component as an example, the wireless control can be used to control brightness and on / off states. However, the on / off state is primarily based on the attitude information detected by the gyroscope module 15. That is, if the control module 14 controls the power-off based on the attitude information, the wireless control capability will be lost. The wireless module can be Bluetooth, WiFi, or other wireless connection methods, and is not limited here.

[0040] In summary, the head-mounted device provided in this application has at least the following advantages: 1. By setting up the gyroscope module 15, there is no need to open the button mounting hole in the housing 11, which reduces the probability of external moisture entering the housing 11 and extends the service life of the equipment. 2. A wireless charging module is provided. The power supply 13 is charged through the wireless charging module, eliminating the need for a charging port and a battery insertion / removal port, which further improves the sealing performance of the housing 11.
