Description

Technical Field

[0001] The utility model relates to the field of sensors, and particularly to an induction device. Background Art

[0002] With the development of intelligent control technology, more and more sensors are popularized in people's lives. Based on the detection results of the presence of the human body, human activities, etc., the sensors correspondingly control the corresponding electrical devices. With the development of whole-house intelligence, the Internet of Things, etc., at present, the use of many sensors is no longer limited to controlling a single electrical device, but is connected to a gateway. Based on the feedback of the detection results, more intelligent control of various devices is realized. Therefore, in addition to the components required for sensing, many sensors also need to be provided with communication antennas, initial network access switch buttons, etc. When the sensor is enabled, pressing the switch button makes the sensor enter the matching connection mode, and the antenna is used to send the corresponding detection results, receive the corresponding instructions, etc.

[0003] At present, in sensors, most of the antennas used for communication are vertical antennas, such as helical antennas, columnar antennas, etc. And in order to ensure the communication quality, the vertical antenna needs to be protruded on the front of the sensor housing to avoid the signal being blocked and shielded by the sensor housing. At the same time, in order to facilitate the user to operate the switch button, the switch button is generally also set on the protruding sensor housing to facilitate the user to press the switch button downward. Taking an infrared sensor as an example, at least a Fresnel lens, an antenna cover, and a switch button need to be protruded on the front of the sensor housing. On the one hand, the protruding setting of multiple components affects the aesthetic degree of the sensor, and since these protruding parts are exactly facing the target sensing area of the sensor during installation and cannot be hidden relative to the user, many users have concerns about the selection of the sensor due to aesthetic problems. On the other hand, due to the protrusion of the components, the sensor housing needs to have a corresponding protruding matching design. For example, the housing needs to be provided with an opening for the antenna to pass through, and an antenna cover covering the antenna and installed on the housing also needs to be matched. Therefore, the more protruding components there are, the more complex the design of the housing is. And for the purpose of waterproof and dustproof, each protruding design needs to be closely matched with the morphological design of each opening. The more protruding components there are, the more complex the waterproof and dustproof design of the sensor is. Summary of the Utility Model

[0052] The following description is used to disclose the present utility model so that those skilled in the art can implement the present utility model. The preferred embodiments described below are only examples, and other obvious variations can be conceived by those skilled in the art. The basic principles defined in the following description of the present utility model can be applied to other implementation manners, deformation schemes, improvement schemes, equivalent schemes, and other technical schemes without departing from the spirit and scope of the present utility model.

[0053] Those skilled in the art should understand that in the disclosure of the present utility model, the orientation or positional relationship indicated by the terms "longitudinal", "transverse", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc. is based on the orientation or positional relationship shown in the drawings. It is only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, the above terms should not be construed as limitations on the present utility model.

[0054] It can be understood that the term "a" should be understood as "at least one" or "one or more". That is, in one embodiment, the number of an element can be one, while in other embodiments, the number of the element can be multiple. The term "a" should not be construed as a limitation on the number.

[0055] Referring to the specification drawings of the present utility model Figures 1 to 4As shown, an induction device 100 according to an embodiment of the present utility model is schematically shown. Based on the regular design of components, the induction device 100 can reduce the number of protrusions on the surface to improve the aesthetic effect. Specifically, the induction device 100 includes a housing 10, a multi-functional button 20, and a circuit main board 30. The circuit main board 30 carries an induction module 31, a vertical antenna 33, and a switch 32 on the same surface. The housing 10 defines a receiving cavity 101, and the circuit main board 30 is accommodated in the receiving cavity 101. With the surface of the circuit main board 30 carrying the induction module 31 facing upward, the housing 10 has an antenna opening 1101 corresponding to the vertical antenna 33 on the upper side of the circuit main board 30. The multi-functional button 20 has a support base 21 and a button cap 22. The multi-functional button 20 is arranged in a state where the support base 21 is elastically supported in the receiving cavity 101, and correspondingly forms a state where the support base 21 faces the switch 32, and the button cap 22 passes through the antenna opening 1101. The vertical antenna 33 penetrates into the button cap 22. When the support base 21 is elastically supported and the multi-functional button 20 is pressed, the height of the button cap 22 protruding from the antenna opening 1101 decreases, and the switch 32 is abutted by the multi-functional button 20 and triggered. Thus, the vertical antenna 33 is covered by the multi-functional button 20, and the switch 32 is triggered by the multi-functional button 20. The structural design is more regular, enabling the multi-functional button 20 to have the advantage of serving two purposes, thereby reducing the number of protrusions on the housing 10 and enhancing the aesthetics of the induction device 100.

[0056] That is to say, in the present utility model, the induction device 100 uses the antenna cover 20 that originally needs to be protruded as the driving key for driving the switch 32, so that the multi-functional button 20 serves both as an antenna cover for shielding and protecting the vertical antenna 33 and as a button for driving the switch 32. Based on the regular structural design, there is no need to additionally protrude an antenna cover or a button on the housing 10, reducing the number of protrusions on the housing 10 and effectively enhancing the aesthetic degree of the induction device 100. It can be understood that the specific function of the switch 32 does not limit the present utility model. During specific implementation, the switch 32 can be set to enter the Reset or other special function modes by being long-pressed for three seconds, so as to prevent accidental triggering caused by short pressing. That is to say, the operator long-presses the multi-functional button 20 for three seconds to drive and press the switch 32 for three seconds through the multi-functional button 20 to trigger the corresponding function. Of course, the specific long-press time does not limit the present utility model, and the pressing duration can be set according to needs during specific implementation.

[0057] It is worth mentioning that in the present utility model, in addition to being used as an antenna cover and a button, the multifunctional button 20 can also be used as a light guiding component to further reduce the number of protrusions of the sensing device 100. Specifically, on the surface of the circuit board 30 where the vertical antenna 33 is carried, at least one of a light sensing element 34, an indicator light 35, and an infrared receiver 36 is carried. The light sensing element 34 and / or the indicator light 35 and / or the infrared receiver 36 carried by the circuit board 30 is / are located below the multifunctional button 20. The position of the multifunctional button 20 corresponding to the light sensing element 34 and / or the indicator light 35 and / or the infrared receiver 36 has a light transmissive design from top to bottom, thereby forming a light guiding channel for the light sensing element 34 and / or the indicator light 35 and / or the infrared receiver 36 disposed below the multifunctional button 20, so that the light sensing element 34 and / or the indicator light 35 and / or the infrared receiver 36 can receive / emit light through the multifunctional button 20. Then, the multifunctional button 20 not only covers the vertical antenna 33 and drives the switch member 32, but also has a light guiding effect, so that no additional protruding light guiding portion needs to be provided on the surface of the housing 10, further improving the regularity of the structural design, reducing the number of protrusions on the housing 10, and further enhancing the aesthetics of the sensing device 100.

[0058] Specifically, referring to Figure 2 As shown, specifically in this structure of the present utility model, the circuit board 30 carries the light sensing element 34, the indicator light 35, and the infrared receiver 36. The light sensing element 34 and the indicator light 35 are located below the multifunctional button 20 to be able to receive / emit light based on the multifunctional button 20. The infrared receiver 36 is close to the sensing module 31 and can share a protrusion with the sensing module 31 to receive light.

[0059] Furthermore, the multifunctional button 20 extends downwardly and protrudingly from the support base 21 to have a touch post 24. The touch post 24 protrudes from the support base 21 to abut against and trigger the switch member 32 when the multifunctional button 20 is pressed, thereby being able to reduce the pressing stroke of the multifunctional button 20.

[0060] Particularly, the support base 21 extends downwardly and protrudingly to have a light guiding portion 25. The light sensing element 34 and / or the indicator light 35 and / or the infrared receiver 36 is / are located below the light guiding portion 25, so that the light guiding portion 25 forms a light guiding effect on the light sensing element 34 and / or the indicator light 35 and / or the infrared receiver 36, and ensures that the corresponding devices can receive / emit light.

[0061] It is worth mentioning that the key cap 22 defines a receiving cavity 201, and the vertical antenna 33 passes through the key cap 22 and is located in the receiving cavity 201. Corresponding to the state where the key cap 22 penetrates out of the antenna port 1101, the vertical antenna 33 protrudes from the antenna port 1101 in the key cap 22 to avoid being blocked by the housing 10 and ensure the communication effect of the vertical antenna 33.

[0062] Particularly, to ensure the stability of the vertical antenna 33, the distance H1 between the top 221 of the key cap 22 and the vertical antenna 33 is greater than the distance H2 between the touch post 24 and the switch member 32. When the multifunctional key 20 is pressed to trigger the switch member 32, the multifunctional key 20 is prevented from contacting the vertical antenna 33, ensuring the safety of the vertical antenna 33.

[0063] Furthermore, the housing 10 includes an upper cover body 11 and a lower housing 12. The lower housing 12 has a groove body 121 and an opening edge 122. The groove body 121 defines a receiving groove and an opening communicating with the receiving groove. The opening edge 122 extends outwardly convex from the opening and protrudes from the groove body 121. The upper cover body 11 has a surface cover plate 111 and an installation wall 112 extending downward from the surface cover plate 111. The antenna port 1101 is opened on the surface cover plate 111. The installation wall 112 matches the opening edge 122 so that the upper cover body 11 can be covered on the lower housing 12, thereby forming the receiving cavity 101 between the upper cover body 11 and the lower housing 12. The multifunctional key 20 extends from the support base 21 with an installation portion. The installation portion has a positioning hole 231. The lower housing 12 extends upward from the opening edge 122 with a positioning post 123 matching the positioning hole 231. The multifunctional key 20 is installed in a state where the positioning hole 231 is inserted by the positioning post 123 and is arranged in the housing 10 based on the upper cover body 11 being covered on the lower housing 12.

[0064] Particularly, the installation portion includes four elastic support feet 23 extending from the support base 21, and each of the elastic support feet 23 has one positioning hole 231 to ensure the installation stability of the multifunctional key 20.

[0065] It is worth mentioning that the elastic support feet 23 are elastically designed so that the multifunctional key 20 is elastically supported in the receiving cavity 101 and can form buffering and reset for the pressing movement of the multifunctional key 20, thereby ensuring the key function of the multifunctional key 20.

[0066] In particular, in the present utility model, the induction module 31 is implemented as an infrared probe, and a Fresnel lens 13 is correspondingly provided on the surface cover plate 111.

[0067] Furthermore, referring to the accompanying drawings of the specification of the present utility model Figure 5 and Figure 6 as shown, in order to adjust the induction range of the induction device 100, in this variant embodiment of the present utility model, the induction device 100 further includes a light-shielding cover 40, and the light-shielding cover 40 is adapted to be sleeved on the Fresnel lens 13 to form partial shielding of the Fresnel lens 13, thereby realizing the adjustment of the induction range of the induction device 100.

[0068] Specifically, referring to Figure 2 , Figure 5 and Figure 6 , the surface cover plate 111 extends outwards around the Fresnel lens 13 to have a mounting convex ring 113. The light-shielding cover 40 has a rotary connection ring 41 and a light-shielding portion 42. The rotary connection ring 41 defines an inner ring opening 401. The rotary connection ring 41 is matched with the mounting convex ring 113 to have a ring groove 411. The light-shielding cover 40 is adapted to be installed in a state where the ring groove 411 is sleeved on the mounting convex ring 113. In the state where the ring groove 411 is sleeved on the mounting convex ring 113, the Fresnel lens 13 passes out from the inner ring opening 401 and is partially shielded by the light-shielding portion 42. Thus, based on the shielding of the Fresnel lens 13 by the light-shielding portion 42, the adjustment of the induction range of the induction device 100 is realized. The light-shielding cover 40 is selectively installed to select whether to install the light-shielding cover 40 based on the usage needs.

[0069] In particular, the mounting convex ring 113 has at least one buckle 1131 protruding radially outwards therefrom. In the state where the ring groove 411 is sleeved on the mounting convex ring 113, the buckle 1131 cooperates with the ring groove 411 to realize the installation of the light-shielding cover 40 and facilitate the rotation of the light-shielding cover 40, thereby adjusting the shielding area of the light-shielding portion 42 on the Fresnel lens 13.

[0070] It is worth mentioning that the light-shielding portion 42 is designed to be cuttable so that the shielding range of the light-shielding portion 42 on the Fresnel lens 13 can be adjusted based on the cutting of the light-shielding portion 42. The light-shielding portion 42 is provided with a cutting guide seam 421, so that the user can quickly complete the cutting of the light-shielding portion 42 based on the cutting guide seam 421. For example Figure 15as shown, where the light-shielding portion 42 is cropped in half compared to Figure 5 the structure shown. It can be understood that the light-shielding portion 42 can also be cropped at other angles, and the present utility model does not limit this.

[0071] Furthermore, based on the current trend of miniaturization of sensors, the infrared probe and the Fresnel lens 13 are preferably designed to be miniaturized. Therefore, when the space covered by the Fresnel lens 13 is relatively narrow and the light guiding to the infrared receiver 36 needs to be considered, there are more stringent requirements for the infrared receiver 36 on the circuit board 30. Also, it is necessary to ensure that the position corresponding to the infrared receiver 36 is not the induction area that the user needs to shield, so as to avoid the infrared receiver 36 being blocked by the light-shielding portion 42, resulting in a high difficulty in laying out the infrared receiver 36 on the circuit board 30. Therefore, referring to Figure 7 as shown, in this variant embodiment of the present utility model, the light-sensitive element 34, the indicator light 35, and the infrared receiver 36 are all arranged below the multifunctional button 30, so as to conduct light based on the multifunctional button 30 and avoid the problems of increased difficulty in laying out the circuit board caused by arranging the infrared receiver 36 under the Fresnel lens 13 and the Fresnel lens 13 corresponding to the upper part of the infrared receiver 36 not being able to be blocked.

[0072] It is worth mentioning that the light-transmitting design of the multifunctional button 20 easily causes the user to see the vertical antenna 33 from the top 221 of the button cap 22, that is, the top of the multifunctional button 20.
