Description

Technical Field

[0001] The utility model relates to the field of housings for electronic / electrical equipment, and in particular to a housing with a light guide column, a sensor, and a power supply. Background Art

[0002] For devices such as power supplies and sensors, feedback on their working status is generally achieved through indicator lights. The debugger / user can learn about the working status of the device by observing the status of the indicator lights. Therefore, the housing of such devices needs to have a through hole for the indicator lights to lead out, so that the indicator lights fixed on the circuit board can be exposed from the inside of the housing. Figure 1A As shown, an existing sensor device 1P of the applicant is illustrated, in which an indicator light 11P is mounted on a circuit board 13P via a metal foot 12P. When the housing 14P of the sensor device 1P is covered on the circuit board 13P, the metal foot 12P raises the indicator light 11P, and the indicator light 11P can pass through the through-hole 141P on the housing 14P without being blocked by the housing 14P, thereby ensuring that the outside world can normally understand the indication of the indicator light 11P. In practice, the applicant found that in order to meet the requirement that the indicator light 11P can pass through the housing 14P, the metal foot 12P needs to be set at a relatively high height, resulting in a decrease in strength and easy bending and deformation, which affects the installation security of the indicator light 11P.

[0003] For this problem, refer to Figure 1B As shown, an improved structure is illustrated. The applicant has installed a spacer column 15P around the metal foot 12P to strengthen the structural strength of the metal foot 12P and provide support for the indicator light 11P, ensuring the secure installation of the indicator light 11P. Although this structure ensures the installation stability of the indicator light 11P, the addition of the spacer column 15P undoubtedly increases the production process of the sensor device 1P, reduces the production efficiency of the sensor device 1P, and increases additional production costs.

[0047] refer to Figures 2 to 4, a housing 10 with a light guide according to an embodiment of the present invention is illustrated. In these examples, the housing 10 with a light guide is applied to a microwave sensor 20 and used as a sensor housing. The housing 10 with a light guide column includes a housing body 11 and at least one light guide column 12, wherein the housing body 11 has a panel 111, and the panel 111 is provided with a light-transmitting window 110, so that the corresponding light-emitting and / or photosensitive devices accommodated in the housing 10 with the light guide column can transmit / receive light through the light-transmitting window 110. Specifically corresponding to these examples, the microwave sensor 20 includes a circuit board 21, a sensing unit 22 and at least one light device 23, wherein the circuit board 21 carries the sensing unit 22 and the light device 23, wherein the light device 23 can be a light-emitting device or a photosensitive device, such as but not limited to a photosensitive device, an indicator light, an infrared receiver, a light-emitting LED, an infrared emitting tube, etc. That is, the light device 23 is used to emit light to indicate the working status of the microwave sensor 20, or to receive or detect corresponding light signals. When the circuit board 21 is accommodated in the housing body 11, the light device 23 can transmit / receive light through the light-transmitting window 110. The light guide column 12 is accommodated in the shell body 11 with one end thereof facing the light-transmitting window 110. When the circuit main board 21 is accommodated in the shell body 11, the other end of the light guide column 12 faces the optical device 23 to form a light-guiding channel between the light-transmitting window 110 and the corresponding device, so as to guide the light emitted by the corresponding optical device 23 to the light-transmitting window 110, thereby emitting light to the outside to indicate the working status of the microwave sensor 20, or guiding external light from the light-transmitting window 110 to the corresponding optical device 23, so that the corresponding light signal is received by the optical device 23. In this way, the optical device 23 does not need to be elevated in the circuit main board 21, which not only ensures the installation stability of the device but also reduces production costs.

[0048] It is worth mentioning that the light guide column 12 extends from the panel 111 to the inside of the shell body 11 in the light-transmitting window 110 and is integrated with the panel 111, which is conducive to simplifying the corresponding production process of the shell 10 with the light guide column, thereby improving production efficiency and reducing production costs.

[0049] Furthermore, the sensing unit 22 includes a reference ground 222 and a pair of dual coupling poles 221, so that when the sensing unit 22 is fed by the corresponding feeding signal, the directional radiation direction of the sensing unit 22 is formed in the direction of the reference ground 222, wherein the pair of dual coupling poles 221 includes a first radiation source 2211 and a second radiation source 2212, wherein the first radiation source 2211 has a first feeding end 2201, and the second radiation source 2212 has a second feeding end 2202, and the first radiation source 2211 is configured as a conductor extending from the first feeding end 2201 as an end, wherein the second radiation source 2212 is configured as a conductor extending from the second feeding end 2202 as an end, wherein the first radiation source 2211 and the second radiation source 2212 are respectively The first feeding end 2201 and the second feeding end 2202 have a line length greater than or equal to λ / 16, the second feeding end 2202 and the first feeding end 2201 are close to each other and the distance between the second feeding end 2202 and the first feeding end 2201 is less than or equal to λ / 4, and the distance between the first feeding end 2201 and the second feeding end 2202 and the reference ground 222 is greater than or equal to λ / 32, where λ is a wavelength parameter corresponding to the frequency of the feeding signal. The housing body 11 defines an accommodating cavity 101 and a convex portion 112 protrudes from the panel 111. A convex groove 1120 is defined from the accommodating cavity 101 corresponding to the convex portion 112. The sensing unit 22 is accommodated in the accommodating cavity 101 with the pair of coupled poles 221 located in the convex groove 1120.

[0050] In particular, the specific appearance of the shell body 11 does not constitute a limitation to the present invention. For example, in some embodiments, the shell body 11 can be designed to be transparent. In some embodiments, the shell body 11 can be designed to be translucent. For example, the protrusion 112 is designed to be transparent, and when the sensing unit 22 is accommodated in the accommodating cavity 101, the dual coupling pole 221 can be visualized based on the transparent design of the protrusion 112. In some embodiments, the shell body 11 can also have color, which is not limited by the present invention.

[0051] In this embodiment of the present invention, the circuit main board 21 further carries a dip switch 24, wherein the dip switch 24 is used to adjust relevant operating parameters of the microwave sensor 20, wherein the panel 111 is provided with a subsidence switch position 113, wherein the subsidence switch position 113 is subsided from the panel 111 to the interior of the shell body 11 and has a switch window 1130, wherein when the circuit main board 21 is accommodated in the accommodating cavity 101, the dip switch 24 is exposed from the switch window 1130, wherein the subsidence design based on the subsidence switch position 113 facilitates the debugger or user to operate the dip switch 24 without the aid of tools, thereby facilitating the adjustment of the microwave sensor 20.

[0052] It is worth mentioning that the surface of the light-transmitting window 110 is designed with a high-gloss treatment to improve the light-guiding efficiency of the light-transmitting window 110, which is beneficial to reducing the transmission loss of the light-transmitting window 110 to the light. In this way, when the light-guiding column 12 guides the light emitted by the optical device 23 to the light-transmitting window 110, the brightness of the light emitted by the light-transmitting window 110 is guaranteed to ensure that the corresponding indication can be obtained. When the light-guiding column 12 guides the external light from the light-transmitting window 110 to the corresponding optical device 23, the receiving efficiency of the corresponding optical device 23 for the light signal is improved, thereby ensuring the sensitivity of the regulation.

[0053] Specifically, the method of designing the high-gloss treatment on the surface of the light-transmitting window 110 does not constitute a limitation to the present invention, such as but not limited to improving the light guiding efficiency by coating the surface of the light-transmitting window 110, improving the light guiding efficiency by grinding / polishing the surface of the light-transmitting window 110, etc.

[0054] In particular, with reference to the accompanying drawings of the present invention, Figure 5 , the housing 10 with the light guide column includes a light-transmitting convex 114, wherein the light-transmitting window 110 is covered by the light-transmitting convex 114, so as to increase the light irradiation / receiving area of ​​the housing 10 with the light guide column based on the protruding design of the light-transmitting convex 114 on the panel 111, and based on the protrusion of the light-transmitting convex 114, it is convenient for the installation and positioning of the housing 10 with the light guide column, and can avoid the light-transmitting window 110 being blocked by the corresponding installation surface. For example, when the housing 10 with the light guide column is installed on a lamp panel, due to the presence of the light-transmitting convex 114, it is necessary to open a corresponding hole on the lamp panel to embed the light-transmitting convex 114 in order to complete the installation of the housing 10 with the light guide column, thereby effectively preventing the problem of the light window 110 being completely blocked due to the lamp factory not opening a hole.

[0055] It is worth mentioning that the transparent convex hull 114 is designed to be transparent, which is beneficial to improving the light guiding efficiency of the transparent convex hull 114 and reducing the transmission loss of the light by the transparent convex hull 114 .

[0056] In particular, with reference to the accompanying drawings of the present invention, Figure 6 A modified embodiment of the housing 10 with a light guide column is illustrated. Specifically, in this modified embodiment, the light-transmitting window 110 is designed to be sunken to form a light-receiving groove, which is beneficial to increasing the light irradiation / receiving area of ​​the housing 10 with the light guide column, and can form an identification area of ​​the housing 10 with the inner light guide column for the user to determine the position of the corresponding optical device, improve recognition, and avoid the light-transmitting window 110 being blocked.

[0057] It is worth mentioning that the surface of the light receiving slot is effectively designed with a high-gloss treatment to enhance the recognition of the light-transmitting window 110 so that the user can determine the position of the corresponding light device.

[0058] In particular, based on the design of the housing 10 with the light guide, the corresponding optical device 23 no longer needs to be elevated, thus avoiding the problems of low strength and complex manufacturing processes caused by the elevated design of the optical device 23. Based on the design concept of the present invention, the scope of application of the housing 10 with the light guide is not limited to the microwave sensor 20 described above, but is also applicable to other devices with the optical device 23, such as infrared sensors, power supplies, etc.

[0059] Corresponding to Figure 7 As shown, a modified embodiment of the microwave sensor 20 is illustrated, wherein in this modified embodiment, the microwave sensor 20 further includes a wireless communication module 25, wherein the wireless communication module 25 is erected on the circuit main board 21, wherein the shell body 11 has a second protrusion 115 protruding from the panel 111, and the second protrusion 115 defines a second protruding groove 1150 in the accommodating cavity 101, wherein the circuit main board 21 is accommodated in the accommodating cavity 101 with the wireless communication module 25 extending into the second protruding groove 1150.

[0060] Corresponding to Figure 8As shown, a modified embodiment of the microwave sensor 20 is illustrated. In this modified embodiment, the dual coupling pole 221 is carried on an antenna substrate in the form of a strip conductor and is designed to be onboard. By adjusting the extension direction of the dual coupling pole 221, the volume of the sensing unit 22 is reduced, which is conducive to correspondingly reducing the volume of the protrusion 112. Therefore, when the microwave sensor 20 is used in a lamp, the reduction in the volume of the protrusion 112 is conducive to reducing the degree of light blocking by the protrusion 112, which is conducive to reducing the situation of dark areas in the lamp.

[0061] Corresponding to Figure 9 As shown, a variant embodiment of the microwave sensor 20 is illustrated, wherein in this variant embodiment, the dual coupling poles 221 are arranged at the side of the reference ground 222, that is, the corresponding pair of dual coupling poles 221 are arranged in a state where the line segment connecting the projection points of the first feeding end 2201 and the second feeding end 2202 on the reference ground 222 deviates from the physical center point of the reference ground 222, so that when the microwave sensor 20 is applied to a strip lamp, the structural design and performance parameters of the microwave sensor 20 can reach a matching relationship with the structure of the strip lamp, the directional radiation performance of the microwave sensor 20 in the lighting direction of the strip lamp will not be destroyed due to the obstruction of the strip light panel, and the strip lamp will not form a dark area due to the installation of the microwave sensor 20 in the lighting state. It is worth mentioning that Figure 8 In the case where the dual coupling pole 221 is designed to be onboard, the dual coupling pole 221 can also be correspondingly set at the side of the reference ground 222.

[0062] Corresponding to Figure 10 As shown, the housing 10 with the light guide column can also be used in a power supply and used as a power supply housing, wherein the Figure 10What is shown is a microwave induction integrated power supply using the shell 10 with the light guide column, wherein the microwave induction integrated power supply includes the circuit main board 21, the sensing unit 22, the optical device 23 and a power circuit 30, wherein the sensing unit 22, the optical device 23 and the power circuit 30 are carried on the circuit main board 21. When the circuit main board 21 is accommodated in the shell body 11, the other end of the light guide column 12 faces the optical device 23 to guide the light emitted by the corresponding optical device 23 to the light-transmitting window 110, so that light can be emitted to the outside to indicate the working status of the microwave sensor 20, or external light can be guided from the light-transmitting window 110 to the corresponding optical device 23, so that the corresponding light signal is received by the optical device 23. In this way, the optical device 23 does not need to be elevated in the circuit main board 21, which not only ensures the installation stability of the device but also reduces the production cost. It is understandable that the housing 10 with the light guide column can also be used as an ordinary power supply housing, and is not limited to the microwave induction integrated power supply shown in the embodiment of the present utility model.

[0063] It is worth mentioning that in Figure 10 In the illustrated embodiment, the sensing unit 22 is implemented as a planar antenna. That is, the specific structure of the sensing unit 22 can be varied, and the present invention does not impose any limitation thereto.
