Description

TECHNICAL AREA

[0001] The present utility model solution concerns the field of intelligent monitoring technology and specifically relates to a housing design for a millimeter wave sleep direction measurement system for infants and toddlers. TECHNICAL BACKGROUND

[0002] Most devices for monitoring the sleep of infants and toddlers rely on cameras, wearable sensors, or pressure sensors placed under the mattress. Such devices often require complicated installation or must be in direct contact with the child's or infant's body, which can lead to issues regarding privacy, safety, or comfort.

[0003] In recent years, millimeter-wave radar has been increasingly used in vital sign monitoring due to its non-contact and highly sensitive properties. However, in practice, the radar is extremely sensitive to its installation position, orientation, housing material, and surrounding structure. In existing products or prototypes, the radar module is often directly exposed or simply mounted in a standard housing, causing the following problems: The unstable mounting of the radar module leads to a shift in the monitoring area; metallic or inadequately constructed components obscure or dampen millimeter wave signals; in addition, the mounting of the internal circuitry is simple and exhibits insufficient resistance to vibrations and displacements.

[0004] Therefore, we have developed a housing design for a millimeter wave sleep monitoring device for infants and toddlers to solve the aforementioned problems. CONTENT OF THE PRESENT APPLICATION(I) Problems of problem solving

[0005] To overcome the disadvantages of the existing technology, the present utility model solution provides a housing design for a millimeter wave sleep direction device for infants and toddlers, thereby solving the problems described in the previous section. (II) Technical solution

[0006] To achieve the aforementioned objectives, the present utility model solution implements the following technical solution: A housing design for a millimeter-wave sleep monitoring device for infants and toddlers, comprising a hard plastic enclosure. Inside the enclosure are a primary and secondary mounting platform, as well as an area for mounting the radar module. Each side wall of the enclosure features a sound transmission window, a control switch port, and a charging port.

[0007] The described hard plastic shell has a reduced-surface, box-shaped structure and thus offers physical protection against external damage.

[0008] The first and second mounting platforms serve to secure and protect the control board and the power supply board.

[0009] The mounting zone for the radar module serves to attach the millimeter wave radar module and to determine its mounting orientation.

[0010] The aforementioned wavelength window, which corresponds to the position of the radar module installation area, serves for the normal transmission and reception of millimeter wave signals.

[0011] The provided connections for power supply and charging serve to connect and configure the device.

[0012] Furthermore, the first and second mounting platforms together consist of at least seven internal threaded columns, the bores of which correspond to the respective positions on the circuit board and the power supply board.

[0013] Furthermore, the mounting zone of the radar module includes at least two slots for attaching the transmitter and receiver for millimeter wave radars.

[0014] In addition, a threaded hole is provided at the mounting zone of the radar module, which is located in the side wall of the insertion joint.

[0015] Furthermore, the threaded holes are located at both ends of the slot and correspond to the holes of the transmitter and receiver of the millimeter-wave radar. Additionally, the switch reservation and the wavelength window are located on the same side, with the wavelength window corresponding to the position of the connector.

[0016] In addition, the edge of the hard plastic housing is rounded to reduce the risk of safety hazards from visible edges of the device for infants and young children. (III) Beneficial effects

[0017] Compared to existing technologies, the present utility model solution offers a housing design for a millimeter-wave sleep direction device for infants and toddlers, which provides the following advantages: The present utility model solution enables dual mounting of the millimeter-wave radar through the design of plug holes and threaded holes in the radar module's mounting area. The plug holes define the mounting orientation, while the threaded holes are precisely aligned with the module's mounting holes, ensuring stable mounting and preventing displacement of the surveillance area. The waveguide window, which aligns with the radar module's mounting area, reduces structural interference along the signal path and increases the efficiency of transmitting and receiving millimeter-wave signals, thereby enhancing surveillance sensitivity. The mounting platform consists of internally threaded support posts and provides multi-stage support for the circuit board. This design improves the vibration and displacement resistance of the internal circuitry. BRIEF DESCRIPTION OF THE DRAWINGS Fig. shows the structure of the present utility model.

[0019] The technical solution according to the exemplary embodiments of the present utility model solution is described clearly and completely below with reference to the accompanying drawings. Obviously, the described exemplary embodiments represent only a portion of the possible embodiments of the present utility model solution, but not all of them. All further embodiments that a person skilled in the art develops without creative effort based on the present exemplary embodiments fall within the scope of protection of the present utility model solution. Example

[0020] As in the Fig. , Fig. , Fig. until Fig. As shown, one embodiment of the present utility models provides a housing structure for a millimeter-wave bedroom monitoring device for infants and toddlers. The housing consists of a rigid plastic housing 1 in which a first mounting platform 2, a second mounting platform 3, and an area for mounting the radar module 4 are arranged. A wave-compatible window 5, a control switching port 6, and a charging port 7 are provided on each of the housing's side walls. The cable socket in the radar module mounting area 4 and the threaded hole 8 ensure dual mounting of the millimeter-wave radar: The cable socket determines the mounting orientation, while the threaded hole 8 aligns precisely with the module's mounting hole, thus ensuring stable mounting of the module and preventing displacement of the monitoring area.The wave-matched window 5, aligned with the radar module mounting area 4, reduces structural interference along the signal path and increases the efficiency of transmitting and receiving millimeter-wave signals, thereby enhancing surveillance sensitivity. The installation platform consists of internal threaded posts that support the circuit board at multiple points. This design improves the vibration and displacement resistance of the internal circuitry.

[0021] The described hard plastic shell 1 has a reduced-surface, box-shaped structure and offers a physical protective function against external damage.

[0022] The first and second mounting platforms 2 and 3 serve to secure and protect the control board and the power supply board.

[0023] Mounting zone 4 of the radar module serves to attach the millimeter wave radar module and to determine its mounting orientation.

[0024] The aforementioned wavelength window 5, which corresponds to the position of the radar module installation area 4, serves for the normal transmission and reception of millimeter wave signals.

[0025] The designated ports 6 and 7 are used for power supply and configuration of the device.

[0026] How Fig. As shown, in some embodiments, the first mounting platform 2 and the second mounting platform 3 each consist of at least seven internal threaded columns that precisely align with the holes in the circuit board and the power supply board. The columns fit snugly against the holes and are secured by spring-loaded self-drilling screws, creating multiple support points. This design significantly improves the vibration and displacement resistance of the internal circuitry. Even in the event of device movement or external impacts, the system remains stable, thus extending its service life.

[0027] How Fig. As shown, mounting zone 4 of the radar module in some embodiments consists of at least two mounting holes for attaching the transmitter and receiver of a millimeter-wave radar. A millimeter-wave radar is a radar system used in the millimeter-wave range (typically 30–300 GHz) for detection and range measurement. Its operating principle is based on the process of emission, propagation, reflection, and reception of electromagnetic waves. Specifically, the system emits millimeter-wave signals at a specific frequency, which propagate through air at the speed of light. When they encounter target objects such as vehicles, pedestrians, or obstacles, portions of the signals are reflected. The radar system's receiving antenna detects these reflected signals.By analyzing the time difference between the reflected and emitted signal, the frequency change (Doppler effect) and the signal strength, key parameters such as distance, speed and angle of the target are precisely calculated.

[0028] How Fig. As shown, a threaded bore 8 is provided in area 4 for mounting the radar module; this bore is located in the side wall of the insertion hole. The combination of the insertion hole in mounting area 4 and the threaded bore 8 enables a dual mounting of the millimeter-wave radar.

[0029] How Fig. As shown, in some embodiments the threaded bores 8 are arranged at both ends of the slot and correspond to the bores of the transmitter and receiver of the millimeter-wave radar. The slot determines the mounting orientation, and the threaded bores 8 fit precisely into the module bores, thus ensuring stable mounting of the module and preventing displacement of the monitoring area.

[0030] How Fig. As shown, in some embodiments the switching reservation 6 and the wavelength window 5 are located on the same side, with the wavelength window 5 corresponding to the position of the connector and simultaneously covering the mounting area 4 of the radar module. This reduces structural interference along the signal path and improves the efficiency of transmitting and receiving millimeter-wave signals.

[0031] How Fig.As shown, in some embodiments the edge of the hard plastic housing 1 has a rounded edge 9, which reduces the risk of safety hazards from visible edges of the device for infants and small children. The rounded edge 9 eliminates sharp edges and chafing on the housing edge, prevents scratches during transport, assembly, or use, and protects mounting surfaces and operators from damage caused by sharp edges, thereby increasing overall safety.

[0032] The device features a hard-encased housing 1, manufactured by injection molding. Inside, a uniformly shaped mounting platform for attaching the circuit board and a positioning structure for mounting the millimeter-wave radar module are integrated. The radar module is positioned within the housing near the wave path. The circuit board and power supply board are secured to the mounting location via spring-loaded holes. The power and signal lines exit through holes in the side wall of the housing. Once the device is switched on, the millimeter-wave radar module operates stably due to the confined space provided by the housing design, thus enabling long-term monitoring of the sleep status of infants and toddlers.The design of slot 4 and threaded hole 8 on the radar module's mounting area ensures dual mounting of the millimeter-wave radar: The slot determines the mounting orientation, while the threaded hole 8 fits precisely into the module's bore, guaranteeing stable mounting and preventing displacement of the surveillance area. The wave passage windows 5 are aligned with the radar module's mounting area 4. By reducing structural interference along the signal paths, the efficiency of the millimeter-wave signals during transmission and reception is improved, thereby increasing surveillance sensitivity. The mounting platform consists of internal threaded posts that provide multi-level support for the circuit board. This design enhances the vibration and displacement resistance of the internal circuitry.

[0033] In summary, the design of the connector and the tap 8 in mounting area 4 of the radar module enables dual mounting of the millimeter-wave radar. The connector determines the mounting orientation, while the tap 8 aligns precisely with the module drill 8, ensuring stable mounting and preventing displacement of the monitoring area. The waveguide window 5, aligned with mounting area 4 of the radar module, reduces structural interference along the signal path and increases the efficiency of transmitting and receiving millimeter-wave signals, thereby enhancing monitoring sensitivity. The mounting platform consists of an internally threaded column body and provides multi-stage support for the circuit board. This design improves the vibration and displacement resistance of the internal circuitry.

[0034] Finally, it should be noted that the above descriptions merely represent preferred embodiments of the present utility model solution and do not limit it. Although the present utility model solution has been explained in detail with reference to the aforementioned embodiments, those skilled in the field may further develop the technical solutions described in these embodiments or replace individual technical features with equivalent alternatives. All modifications, replacement processes, or improvements made in the spirit and according to the principles of the present utility model solution are to be understood as falling within the scope of protection of the present utility model solution.
