Description

Technical Field

[0001] This utility model relates to the field of radar installation technology, and in particular to a portable millimeter-wave radar device. Background Technology

[0002] Millimeter-wave radar is a radar system that uses electromagnetic waves in the millimeter-wave band (wavelength 1-10 mm, frequency 30-300 GHz) for detection. Millimeter-wave radar can continuously transmit and receive signals, enabling real-time monitoring of targets. Furthermore, millimeter-wave radar has relatively low power consumption and good durability during long-term operation.

[0003] Traditional millimeter-wave radar installations indoors are limited by their structural design, requiring either top-mounting or side-mounting to be fixed to the wall based on a pre-designed structural configuration. This means the mounting surface (top or side) is singular, making it unsuitable for diverse installation scenarios. Therefore, to improve the applicability of millimeter-wave radar installations, a device capable of multi-faceted mounting is urgently needed. Utility Model Content

[0028] Please see Figures 1 to 5 , Figure 1 An exploded view of a portable millimeter-wave radar device provided in an embodiment of this utility model; Figure 2 A schematic diagram of the connection components in the portable millimeter-wave radar device provided in this embodiment of the utility model; Figure 3 A schematic diagram of the rear shell of the portable millimeter-wave radar device provided in this embodiment of the utility model.

[0029] See again Figures 1 to 6The portable millimeter-wave radar device provided in this embodiment includes a connecting component 100, a housing 200, a snap-fit ​​component 300, and a radar body 400; the connecting component 100 is fixed to the housing 200; the radar body 400 is snapped into the interior of the housing 200 by the snap-fit ​​component 300; a millimeter-wave radar sensor is provided on the radar body 400;

[0030] The connection assembly 100 includes a first connector 110 and a second connector 120. The first connector 110 is vertically fixed to the second connector 120, and both the first connector 110 and the second connector 120 are provided with at least two connection holes 130. The first connector 110 and the second connector 120 are snapped onto the outer surface of the housing 200. The connection assembly 100 is used to fix the millimeter-wave radar to the wall.

[0031] In this embodiment, unlike traditional millimeter-wave radar mounting devices, a connecting assembly 100 is snapped onto the surface of the housing 200. The connecting assembly 100 includes a first connecting member 110 and a second connecting member 120 that are perpendicular to each other, and both the first connecting member 110 and the second connecting member 120 are provided with at least two connecting holes 130. A suitable wall mounting component is selected based on the wall material (e.g., brick wall, concrete wall, lightweight partition wall, etc.). By adapting the wall mounting component (e.g., high-strength fixing bolts) to the connecting holes 130 on the first connecting member 110 or the second connecting member 120, the millimeter-wave radar mounting device is fixed perpendicularly or parallel to the wall, achieving multi-faceted fixing of the millimeter-wave radar to the wall.

[0032] Specifically, the first connector 110 and the second connector 120 are perpendicular to each other and integrally formed. The first connector 110 and the second connector 120 are snapped onto the outer surface of the housing 200, with the first connector 110 snapping onto the top outer surface of the housing 200 and the second connector 120 snapping onto the side wall outer surface of the housing 200. When the wall fixing component matches the connecting hole 130 on the first connector 110, the millimeter-wave radar can be installed and fixed perpendicular to the wall; when the wall fixing component matches the connecting hole 130 on the second connector 120, the millimeter-wave radar can be installed and fixed parallel to the wall. Furthermore, for walls with a certain tilt angle, installation can be achieved by adjusting the angle of the first connector 110 or the second connector 120 relative to the wall's fixing angle and by selecting a suitable wall fixing component, greatly improving the applicability of the millimeter-wave radar.

[0033] The radar body 400 is located inside the housing 200, and a millimeter-wave radar sensor (not shown in the figure) is installed on the radar body 400. The millimeter-wave radar sensor has the ability to penetrate the environment and can sense dynamic changes in the surrounding environment through smoke, dust, etc. After being fixed to the wall on multiple sides by a portable millimeter-wave radar device, the millimeter-wave radar sensor can achieve multi-angle and all-round detection coverage.

[0034] In one embodiment, such as Figure 2 As shown, the housing 200 includes a front housing 210 and a rear housing 220; the front housing 210 is fixed to the rear housing 220; the rear housing 220 includes a rear housing body 221, a rear housing buckle 222, and a rear housing fixing post 223; the rear housing buckle 222 and the rear housing fixing post 223 are fixed to the first end face of the rear housing body 221, and the first end face of the rear housing body 221 is the end face facing the front housing 210.

[0035] In this embodiment, the front shell 210 is snapped onto the first end face of the rear shell 220, and the front shell 210 and the rear shell 220 are fully fitted together. A plurality of rear shell clips 222 are circumferentially arranged on the first end face of the rear shell body 221, and these clips are disposed around the outer edge of the first end face of the rear shell body 221. The rear shell clips 222 are adapted to the front shell clips 212 to snap the rear shell 220 onto the front shell 210. The snapping of the rear shell clips 222 onto the front shell 210 ensures a tight connection between the front shell 210 and the rear shell 220, preventing loosening.

[0036] Two rear shell fixing posts 223 are spaced apart on the first end face of the top of the rear shell body 221. The rear shell fixing posts 223 are through holes to adapt to the front shell fixing posts 213 on the front shell 210 so as to fix the front shell 210 to the rear shell 220. The front shell 210 and the rear shell 220 are fixed by the adaptation of the front shell fixing posts 213 and the rear shell fixing posts 223, which further enhances the stability of the shell 200.

[0037] By combining the snap-fit ​​method of the rear shell clip 222 and the front shell clip 212, and the fixing method of the rear shell fixing post 223 and the front shell fixing post 213, on the one hand, the stability and reliability of the shell 200 during long-term use can be ensured, which helps to prevent loosening or damage caused by external impact; on the other hand, compared with the screw connection fixing method, the assembly process is simplified, and it is also convenient for disassembly and maintenance.

[0038] In one embodiment, such as Figure 3As shown, the rear shell body 221 further includes a first groove 224, a second groove 225, and a rear shell protrusion; the first groove 224 and the second groove 225 are located on the second end face of the rear shell body 221, and the first end face of the rear shell body 221 faces away from its second end face; the top of the first end face of the rear shell body 221 extends toward the front shell 210 to form the rear shell protrusion; the first connector 110 is adapted to the first groove 224, and the second connector 120 is adapted to the second groove 225.

[0039] In this embodiment, the top of the first end face of the rear shell body 221 extends to the front shell 210 to form a rear shell protrusion. The outer surface of the rear shell protrusion is the surface facing away from the front shell 210, and the inner surface of the rear shell protrusion is the side surface facing the inner surface of the front shell 210. The first end face of the rear shell body 221 is opposite to the second end face, that is, the second end face of the rear shell body 221 is the end face facing away from the front shell body. The first groove 224 and the second groove 225 are both located on the second end face of the rear shell body 221. The first groove 224 is the groove shown on the outer surface of the rear shell protrusion, and the second groove 225 is connected to the first groove 224 and perpendicular to the first groove 224.

[0040] Specifically, the rear shell body 221 can be manufactured using injection molding. During injection mold design, the shape of the rear shell protrusion is designed into the corresponding position within the mold. When the injection material (such as plastic granules) melts at high temperature in the mold and is injected into the cavity, it cools and solidifies to form the rear shell body 221 with the rear shell protrusion. The outer and inner surfaces of the rear shell protrusion naturally form their corresponding shapes after demolding, and their dimensional accuracy can be controlled by the precision of the mold.

[0041] The first connector 110 and the second connector 120 can be made of metal or high-strength engineering plastics. For example, if metal connectors are used, the first connector 110 and the second connector 120 can be manufactured by precision casting or machining (such as turning or milling); if high-strength engineering plastic connectors are used, they can be manufactured by injection molding, and the shape and size of the first connector 110 and the second connector 120 can be precisely designed in the mold design to meet the fitting requirements of the groove on the rear shell 220.

[0042] The first connecting member 110 and the second connecting member 120, which are perpendicular to each other, are adapted to the first groove 224 and the second groove 225, respectively, wherein the first connecting member 110 is adapted to the first groove 224 and the second connecting member 120 is adapted to the second groove 225. Building structures (e.g., houses) typically consist of ceiling walls and vertical walls, with the example of fixing a portable millimeter-wave radar device to a ceiling wall being used for illustration. When the portable millimeter-wave radar device is vertically fixed to the ceiling wall, since the first groove 224 is located at the top of the rear shell body 221, the first connector 110 is adapted to the first groove 224, and the portable millimeter-wave radar device can be vertically fixed to the ceiling wall by bolts passing through the connecting holes 130 on the first connector 110. When the portable millimeter-wave radar device is horizontally fixed to the ceiling wall, since the second groove 225 is located on the surface of the second end face of the rear shell body 221 and is connected to and perpendicular to the first groove 224, the second connector 120 is adapted to the second groove 225, and the portable millimeter-wave radar device can be horizontally fixed to the ceiling wall by bolts passing through the connecting holes 130 on the second connector 120. Therefore, the portable millimeter-wave radar device in this embodiment can be fixedly installed on the wall from multiple sides, which improves its applicability compared to the traditional single installation method that can only be top-mounted or side-mounted.

[0043] In one embodiment, such as Figure 4 as well as Figure 6 As shown, the front shell 210 includes a front shell body 211, a front shell buckle 212, a front shell fixing post 213, a front shell base 214, and a front shell groove; the front shell buckle 212 is circumferentially disposed on the outer edge of the inner surface of the front shell body 211; the front shell fixing post 213 and the front shell base 214 are both located on the inner surface of the front shell body 211; the front shell groove is located at the top of the front shell body 211; the front shell buckle 212 is adapted to the rear shell buckle 222; the front shell groove is adapted to the rear shell protrusion.

[0044] In this embodiment, the front shell buckle 212 is circumferentially disposed on the outer edge of the inner surface of the front shell body 211, corresponding to the rear shell buckle 222 on the rear shell body 221. When the front shell 210 and the rear shell 220 are engaged, simply align and press the front shell buckle 212 on the front shell body 211 and the rear shell buckle 222 on the rear shell body 221 to fix the front shell 210 onto the rear shell 220. The front shell groove and the rear shell protrusion are also correspondingly disposed and adapted to each other. The corresponding and adapted front shell groove and the rear shell protrusion increase the contact area and fit between the front shell 210 and the rear shell 220. After being engaged and fixed, this structure makes the connection between the front shell 210 and the rear shell 220 tighter, further improving the overall structural stability. At the same time, this adapting structure can also disperse external forces to a certain extent, reduce local stress concentration, and reduce the risk of damage to the connecting parts due to long-term stress.

[0045] The front shell body 211 has a multi-faceted, regular curved surface. The front shell fixing post 213 and the rear shell fixing post 223 are correspondingly arranged. When the front shell 210 is snapped onto the rear shell 220, the front shell fixing post 213 is aligned with the through hole on the rear shell fixing post 223. This further strengthens the fixation between the front shell 210 and the rear shell 220, building upon the existing snap-fit ​​fixing mechanism. The snap-fit ​​primarily serves for quick fixation and initial positioning, while the fixing posts can withstand greater tensile or compressive forces, preventing the front shell 210 and the rear shell 220 from separating or misaligning when subjected to external forces (such as collisions or compression).

[0046] Specifically, when installing and fixing the front shell 210 and the rear shell 220, first align the front shell groove with the rear shell protrusion, and then snap the front shell buckle 212 at the front shell groove with the rear shell buckle 222 on the rear shell protrusion. Next, align and fix the front shell fixing post 213 with the rear shell fixing post 223. Finally, align and snap the front shell buckles 212 and rear shell buckles 222 in other areas. At this point, the snap-fit ​​fixing between the front shell 210 and the rear shell 220 is completed.

[0047] Specifically, the front shell base 214 includes a snap-fit ​​plate and a through-hole post; the snap-fit ​​plate is located on one side of the through-hole post; both the snap-fit ​​plate and the through-hole post are fixed to the inner surface of the front shell body 211.

[0048] In this embodiment, the snap-fit ​​plate and through-hole post of the front shell base 214 can be integrally manufactured using injection molding. The material can be an engineering plastic with certain strength and toughness, such as ABS (acrylonitrile-butadiene-styrene copolymer). During the injection mold design, the shape and size of the snap-fit ​​plate and through-hole post must be precisely designed to ensure a good fit with the inner surface of the front shell body 211. The edge of the snap-fit ​​plate can be designed with a certain curvature or bevel shape to facilitate snap-fitting with other components; the diameter of the through-hole post and the thickness of the snap-fit ​​plate are designed according to actual needs.

[0049] The front shell base 214 is fixed to the inner surface of the front shell body 211 via a snap-fit ​​plate and a through-hole post, providing a stable mounting base for the fixing assembly 310. This structure effectively disperses the external forces borne by the fixing assembly 310, preventing it from easily detaching from the front shell body 211 when subjected to tensile, compressive, or vibratory forces. Furthermore, the snap-fit ​​plate and through-hole post can also be used to snap onto other components, enabling the snap-fit ​​of components of different shapes.

[0050] In one embodiment, such as Figure 5 as well as Figure 6 As shown, the snap-fit ​​assembly 300 includes a fixing assembly 310 and a snap-fit ​​member 320; the fixing assembly 310 is snapped onto the inner surface of the front shell body 211 via the front shell fixing post 213 and the front shell base 214; the snap-fit ​​member 320 is snapped between the front shell base 214 and the bottom of the front shell body 211.

[0051] Specifically, the fixing component 310 includes a fixing body 311; a positioning post 312 and a positioning plate 313 are provided on the first end face of the fixing body 311; a positioning block 314 is provided on the second end face of the fixing body 311; the positioning post 312 and the positioning plate 313 abut against the inner surface of the front shell 210; the positioning block 314 abuts against the first end face of the rear shell body 221; the first end face of the fixing body 311 is the end face facing the front shell 210, and its second end face is opposite to its first end face.

[0052] In this embodiment, the front shell base 214 is spaced apart on the inner surface of the front shell body 211 and is parallel to the bottom of the front shell 210. Therefore, the upper surface of the snap-fit ​​member 320 abuts against the front shell base 214, and its lower surface abuts against the bottom of the front shell body 211, so as to snap and fix the quadrilateral snap-fit ​​member 320 to the inner surface of the front shell body 211. The simultaneous abutment of the upper and lower surfaces ensures that the snap-fit ​​member 320 is well constrained in the vertical direction and is not prone to vertical displacement.

[0053] The top two sides of the fastener body 311 are respectively engaged between the front housing fixing posts 213, and the two sides and bottom of the middle part of the fastener body 311 are respectively engaged with the inner surface of the front housing base 214. This multi-directional engagement method allows the fastener body 311 to be effectively fixed in both horizontal and vertical directions. In the horizontal direction, the engagement of the fixing posts restricts the left and right movement of the fastener body 311; in the vertical direction, the engagement of the front housing base 214 prevents the fastener body 311 from shaking up and down. This stable connection method ensures that the fastener body 311 can remain in the correct position when the equipment is subjected to vibration, collision, etc., providing stable support for the subsequently installed components.

[0054] A positioning post 312 and a positioning plate 313 are provided on the end face of the fastener body 311 facing the front shell 210 (i.e., the first end face of the fastener body 311), and a positioning block 314 is provided on the end face of the fastener body 311 facing the rear shell 220 (i.e., the second end face). The positioning post 312 and the positioning plate 313 abut against the inner surface of the front shell, and the positioning block 314 abuts against the first end face of the rear shell body 221. These positioning structures further enhance the connection stability between the front shell 210 and the rear shell 220. The positioning post 312 and positioning plate 313 can make the installation of the fixing body 311 on the inner surface of the front shell 210 more precise, preventing it from rotating or slightly displacing in the plane; the abutment of the positioning block 314 with the rear shell 220 is like a bridge, better connecting the front shell 210 and the rear shell 220 in space, making the relative position between the front shell 210 and the rear shell 220 more accurate, and when subjected to external force, they can share the pressure, reduce local stress concentration, and thus enhance the stability of the entire equipment shell structure.

[0055] In one embodiment, such as Figure 1 as well as Figure 6 As shown, the snap-fit ​​component 320 includes a first snap-fit ​​component 321 and a second snap-fit ​​component 322; the first snap-fit ​​component 321 is provided with a first hollow groove; the second snap-fit ​​component 322 is provided with a second hollow groove; the first hollow groove and the second hollow groove are symmetrically arranged about the central axis of the front shell 210.

[0056] In this embodiment, the first snap-fit ​​component 321 and the second snap-fit ​​component 322 have the same structure, differing only in their mounting and fixing positions. Since the first snap-fit ​​component 321 and the second snap-fit ​​component 322 have the same structure, they can be manufactured using the same mold during production. This standardized production method improves production efficiency and reduces production costs. Furthermore, the identical structure of the first snap-fit ​​component 321 and the second snap-fit ​​component 322 makes quality control easier, facilitating mass production and quality inspection, and ensuring consistent snap-fit ​​component quality. The first snap-fit ​​component 321 and the second snap-fit ​​component 322 are symmetrically arranged about the central axis of the front shell body 211, and are respectively fixed to both sides of the inner surface of the front shell body 211.

[0057] The first connector 321 has a first slot, and the second connector 322 has a second slot. Both slots are used to mount and fix the radar body 400. The symmetrical arrangement of the first and second slots allows for more efficient use of the internal space of the front housing 210. The first and second slots provide additional space for internal components (such as wires), allowing for more flexible layout. For example, wires can be routed through the slots, avoiding clutter and improving the utilization of internal space, while also facilitating maintenance and repair of internal components. Furthermore, the first and second slots can also serve as heat dissipation channels. During operation, the heat generated by the internal components needs to be dissipated promptly; the design of the first and second slots guides airflow, which is beneficial for heat dissipation.

[0058] In one embodiment, such as Figure 1 as well as Figure 6 As shown, the radar body 400 includes a first radar body 410 and a second radar body 420; the first radar body 410 is adapted to the first hollow slot; the second radar body 420 is adapted to the second hollow slot.

[0059] In this embodiment, a millimeter-wave radar sensor is installed on the radar body 400, that is, both the first radar body 410 and the second radar body 420 are equipped with millimeter-wave radar sensors. Millimeter-wave radar sensors have the ability to penetrate the environment, allowing them to sense dynamic changes in the surrounding environment through smoke, dust, etc. Specifically, the millimeter-wave radar sensor operates in the millimeter-wave frequency band, typically 30-300 GHz. The short wavelength of millimeter waves in this band allows the sensor to achieve a narrow beamwidth and high gain using a smaller antenna. The transmitter inside the millimeter-wave radar sensor transmits millimeter-wave signals into space through the antenna. When the signal encounters a target object, part of the signal is reflected back. The receiver inside then receives the reflected signal through the same antenna (single antenna system) or a dedicated receiving antenna (multi-antenna system). The millimeter-wave radar sensor is equipped with a dedicated signal processing unit to process the relatively weak and noisy reflected signals.

[0060] When installing the first radar body 410, slowly insert it into the first hollow slot to ensure that the outer shell of the radar body 400 is in close contact with the inner wall of the hollow slot. It can be fixed by using a slot, buckle or positioning pin or other structure (pre-designed on the hollow slot and the radar body 400) to prevent it from loosening or rotating during use. Similarly, accurately install the second radar body 420 in the second hollow slot. After completion, the installation angle and position of the two radar bodies 400 are precisely calibrated to ensure that their detection direction meets the design requirements.

[0061] The first radar body 410 and the second radar body 420 are respectively installed in the first and second hollow slots, enabling multi-angle and omnidirectional detection coverage. For example, in the field of intelligent security monitoring, targets in different directions can be monitored simultaneously, reducing blind spots, improving the probability of target acquisition and monitoring accuracy, and providing more comprehensive and accurate information for subsequent data analysis and decision-making. In addition, precise installation and adaptation ensure that the detection direction and angle of the radar body 400 are not interfered with, guaranteeing the signal transmission and reception effect of the millimeter-wave radar, which is conducive to improving the radar's ranging, velocity, and angle measurement accuracy, thereby improving the performance of the millimeter-wave radar.

[0062] In one embodiment, such as Figure 6 As shown, the snap-fit ​​assembly 300 further includes a fixing block and a plurality of third connectors 330; the fixing block and the plurality of third connectors 330 are all located inside the housing 200; the plurality of third connectors 330 are adapted to the through-hole post.

[0063] In this embodiment, a fixing block (not shown in the figure) is disposed between the first end face of the fixing body 311 and the inner surface of the front shell body 211. The fixing block is used to fill the gap between the first end face of the fixing body 311 and the inner surface of the front shell body 211, and its size is set according to actual needs. By setting a fixing block between the first end face of the fixing body 311 and the inner surface of the front shell body 211, the potential for loosening is effectively eliminated, so that the fixing body 311, the inner surface of the front shell 210, and the snap-fit ​​320 form a tight whole, which can evenly distribute stress when subjected to force, further enhancing the stability of the structure.

[0064] The third connector 330 can be a screw. After the snap-fit ​​member 320 is snapped onto the inner surface of the front housing 210 by the snap-fit ​​plate, the third connector 330 is inserted through the through hole post to form a multiple fixing structure, which can further enhance the fixing effect of the snap-fit ​​member 320.
