[0029] Please see Figures 1-4This utility model proposes a millimeter-wave sedentary reminder 100, including a housing 10, a mounting base 20, a circuit board 30, a battery 41, a display screen 42, a magnetic component 43, and a millimeter-wave radar 44. The housing 10 includes a front cover 11 and a rear cover 12, which together form a receiving cavity 13. The mounting base 20 is disposed within the receiving cavity 13 and has a mounting groove 21, with the opening of the groove facing the front cover 11. The circuit board 30 is fixed within the mounting groove 21 and at least partially covers the groove opening. The battery 41 is fixed within the mounting groove 21 and electrically connected to the circuit board 30. The display screen 42 is fixed to the side of the circuit board 30 facing the front cover 11 and electrically connected to the circuit board 30. The magnetic component 43 is fixed to the side of the mounting base 20 facing the rear cover 12. The millimeter-wave radar 44 is fixed to the side of the circuit board 30 facing the front cover 11 and electrically connected to the circuit board 30. The millimeter-wave radar 44 is used to transmit and receive millimeter-wave signals.

[0030] In the millimeter-wave sedentary reminder 100 of this application embodiment, the millimeter-wave radar 44 set in front transmits and receives millimeter-wave signals to sense the position change of the user in front, and can accurately detect whether the user is in front of the millimeter-wave sedentary reminder 100, and automatically pauses the timer when the user leaves, making the monitoring of sedentary time more accurate. The millimeter-wave radar 44 can effectively improve the monitoring accuracy, and at the same time, it can be better adapted to other components for fixation by magnetic adsorption 43, making the monitoring method more flexible.

[0031] Specifically, such as Figure 1 As shown, the overall shape of the housing 10 can be a cuboid. The front cover 11 and the rear cover 12 are fastened together to form a hollow cuboid housing 10. The hollow area inside is the receiving cavity, which is used to install components such as the circuit board 30 and the display screen 42. The housing 10 is mainly used to protect the internal components.

[0032] Mounting base 20 is mainly used to install and fix multiple internal components. Mounting base 20 is located in the receiving cavity 13 between the front cover 11 and the rear cover 12. Mounting base 20 is provided with mounting groove 21. The groove of mounting groove 21 faces the rear cover 12 and can be adapted to the interior of the rear cover 12. The opening of mounting groove 21 faces the front cover 11.

[0033] like Figure 3 As shown, the circuit board 30 can be a PCB board, mainly used to control the operation of the millimeter-wave sedentary reminder 100. The circuit board 30 is also located in the receiving cavity 13 and fixedly mounted on the mounting base 20. The circuit board 30 can be configured to cover the entire opening of the mounting groove 21.

[0034] The battery 41 is fixed within the mounting slot 21 and can be shielded by the circuit board 30. The battery 41 is electrically connected to the circuit board 30, thereby providing power to the circuit board 30. In some embodiments, the circuit board 30 may be provided with a charging interface, through which the battery 41 can be charged. Correspondingly, the side of the mounting base 20 or the housing 10 corresponding to the charging interface will have a clearance structure to allow the charging interface to connect to an external power source.

[0035] The display screen 42 may include an e-ink screen, or other types of color screens, etc. This application does not limit the type of display screen 42. The display screen 42 is mounted on the circuit board 30 and electrically connected to the circuit board 30. The display screen 42 faces the front cover 11, and the user can perform operations such as setting reminder duration through the display on the display screen 42. At the same time, the display screen 42 can display the duration of the user's current position, allowing the user to intuitively see the duration so that the user can better control the time spent getting up and moving around, avoiding the harm caused by prolonged sitting.

[0036] The magnetic component 43 may include a magnet or other magnetic elements, and can be fixed to the side of the mounting base 20 facing the rear cover 12. The millimeter-wave sedentary reminder 100 can be fixed by magnetic attachment to other compatible devices, such as magnetic brackets, mobile phones, or ferrous metal panels, through the magnetic component 43, and can be flexibly placed in a suitable position, making the monitoring method more flexible and convenient.

[0037] Millimeter-wave radar 44 is a radar that operates in the millimeter-wave band for detection. It can transmit and receive millimeter-wave signals. Millimeter-wave radar 44 can be mounted on circuit board 30 facing the front cover 11. It transmits millimeter-wave signals forward, and these signals are reflected back when they come into contact with the user in front. When the user is sitting in front of the millimeter-wave sedentary reminder 100, the time difference between receiving and receiving the signal is short. When the user moves, the time difference increases. Therefore, by analyzing the time difference between the transmitted and received signals, the system can accurately monitor whether the user's position has changed, resulting in high monitoring accuracy. Furthermore, compared to facial recognition monitoring using cameras, millimeter-wave radar 44 avoids the risk of privacy leaks.

[0038] Optionally, both the front cover 11 and the rear cover 12 are transparent, or at least the front cover 11 is transparent. The transparency of the front cover 11 and the rear cover 12 allows the user to clearly see the content displayed on the internal display screen 42, as well as its internal structure, enhancing the overall technological feel of the millimeter-wave sedentary reminder 100. Furthermore, the transparency of at least the front cover 11 allows the millimeter-wave radar 44 to better transmit and receive signals, improving the monitoring accuracy of the millimeter-wave radar 44. Of course, in some other embodiments, the area of ​​the front cover 11 corresponding to the display screen 42 can also be made transparent, allowing the user to see the content displayed on the display screen 42.

[0039] Please see Figure 3 Optionally, the millimeter-wave sedentary reminder 100 also includes a metal marker 45, which is mounted on the front cover 11 and is offset from the millimeter-wave radar 44. Since metal components can affect the transmission and reception of signals from the millimeter-wave radar 44, the metal marker 45 and the millimeter-wave radar 44 need to be offset. For example, if the millimeter-wave radar 44 is located in the upper right corner of the circuit board 30, the metal marker 45 can be located in the upper left, lower left, or upper right corner of the front cover 11. If the millimeter-wave radar 44 is located in the upper left corner of the circuit board 30, the metal marker 45 can be located in the upper right, lower right, or lower left corner of the front cover 11. In short, to avoid the metal marker 45 affecting the monitoring effect of the millimeter-wave radar 44, the metal marker 45 and the millimeter-wave radar 44 need to be offset.

[0040] Of course, in some other embodiments, the marker can also be made of other materials that will not affect the millimeter-wave radar 44 signal. This application does not limit the material of the marker.

[0041] Optionally, a fixing groove 22 is formed on the side of the mounting base 20 facing the rear cover 12, and the magnetic component 43 is installed in the fixing groove 22. In this way, the magnetic component 43 can be stably fixed on the mounting base 20, preventing the magnetic component 43 from falling off.

[0042] Specifically, the fixing groove 22 can be formed by recessing the mounting base 20 towards the front cover 11 on the side facing the rear cover 12, and the fixing groove 22 can be formed on both sides of the back of the mounting base 20. The shape of the magnetic component 43 can be adapted to the shape of the fixing groove 22.

[0043] Please see Figure 3 and Figure 4Optionally, a clearance hole 121 is provided in the area corresponding to the fixing groove 22 on the back cover 12, through which the magnetic component 43 can protrude. Thus, the clearance hole 121 enhances the adsorption capacity of the magnetic component 43, allowing the millimeter-wave sedentary reminder 100 to adhere more stably to the designated location. Specifically, the position of the clearance hole 121 can correspond to the position of the fixing groove 22, allowing the magnetic component 43 to protrude through the clearance hole 121, thereby strengthening the adsorption performance of the magnetic component 43.

[0044] Optionally, the millimeter-wave sedentary reminder 100 also includes a fixing member 46 for securing the display screen 42, which is fixedly connected to the circuit board 30. This fixing member 46 ensures a more stable connection between the display screen 42 and the circuit board 30, preventing the display screen 42 from easily separating from the circuit board 30 due to its weight. Simultaneously, since the front cover 11 is transparent, users can directly see the internal structure, and the fixing member 46 also serves a decorative purpose, enhancing the internal design and the technological feel of the millimeter-wave sedentary reminder 100.

[0045] Furthermore, the circuit board 30 can have multiple locking holes 31, which can be located around the periphery of the display screen 42. The fixing member 46 has multiple locking posts 461 on the side facing the circuit board 30, with the locking holes 31 corresponding to the locking posts 461. The locking posts 461 can pass through the locking holes 31, allowing the fixing member 46 to be locked and fixed to the circuit board 30. The display screen 42 is secured between the fixing member 46 and the circuit board 30, ensuring a stable installation of the display screen 42 on the circuit board 30. The locking hole 31 and locking post 461 facilitate easy installation and removal of the fixing member 46 and the circuit board 30, resulting in strong connection stability.

[0046] Please see Figure 3 Optionally, the millimeter-wave sedentary reminder 100 also includes a light sensor 47, which is fixed to the side of the circuit board 30 facing the front cover 11 and electrically connected to the circuit board 30. The light sensor 47 is used to sense external light. Thus, the millimeter-wave sedentary reminder 100 can also sense the intensity of external light through the light sensor 47, and will remind the user when the external light is too strong or too weak, preventing the user from sitting for extended periods in strong or weak light environments and affecting their eyesight. For example, when the ambient light is below 150 Lux, the millimeter-wave sedentary reminder 100 will issue an alarm to remind the user.

[0047] Please see Figure 3 Optionally, the mounting base 20 is provided with a fixing post 23, and the fixing post 23 has a threaded hole 231 on the side facing the circuit board 30. The circuit board 30 is fixed to the mounting base 20 by screws that are threaded into the threaded hole 231. In this way, the connection and fixation between the circuit board 30 and the mounting base 20 by screws can be more stable.

[0048] Specifically, the fixing posts 23 extend upward from the bottom of the mounting groove 21. There can be four fixing posts 23, located at the four corners of the mounting groove 21, and the battery 41 can be located in the area between the four fixing posts 23. The top surface of the fixing post 23 facing the circuit board 30 is provided with a threaded hole 231. Correspondingly, the circuit board 30 is provided with a through hole at the position corresponding to the threaded hole 231. The thread can pass through the through hole and engage with the threaded hole 231, so that the circuit board 30 is fixed to the top of the fixing post 23.

[0049] In some embodiments, the mounting base 20 and the rear cover 12 can also be fixed together by screws. That is, multiple screw holes are provided on the side of the mounting base 20 facing the rear cover 12, and the screws pass through the rear cover 12 and engage with the screw holes to fix the mounting base 20 and the rear cover 12 together. Of course, the mounting base 20 can also be fixed together with the rear cover 12 and the front cover 11 by means of snap-fit ​​connection or other methods. This application does not limit the connection between the mounting base 20 and the rear cover 12 and the front cover 11.

[0050] Please see Figure 3 and Figure 4 Optionally, the millimeter-wave sedentary reminder 100 also includes an anti-scratch pad 48, which is disposed on the rear cover 12 and at least covers the magnetic element 43. Thus, the anti-scratch pad 48 prevents the magnetic element 43 from scratching the surface when the millimeter-wave sedentary reminder 100 is attached to a designated position. Simultaneously, the anti-scratch pad 48 also increases friction, enhancing the attachment performance of the millimeter-wave sedentary reminder 100.

[0051] In summary, the millimeter-wave sedentary reminder 100 of this utility model effectively enhances the accuracy of monitoring through the millimeter-wave radar 44, truly achieving the effect of timing when a person arrives and stopping when the person leaves, greatly enhancing the user experience. Simultaneously, the magnetic attachment 43 allows the millimeter-wave sedentary reminder 100 to be placed in any accessible location, making the monitoring method more flexible.

[0052] The above description is only a preferred embodiment of the present utility model and does not limit the patent scope of the present utility model. All equivalent structural transformations made under the inventive concept of the present utility model using the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
