Description

Technical Field

[0001] The utility model relates to the technical field of intelligent switch panels, in particular to an intelligent switch panel with a hidden proximity sensing structure. Background Art

[0002] As an important part of smart home, the quality of human-computer interaction of smart switch panel directly affects the user's experience. While pursuing the intelligence and convenience of smart home, people also pay attention to the aesthetics of home. Therefore, in the design of smart switch panel, how to meet the functional requirements while taking into account the aesthetics of the appearance has become an urgent problem to be solved. In order to realize the multifunctionality of the panel, the arrangement of the sensing device becomes particularly important. However, the existence of these sensing devices often has a certain impact on the appearance of the panel, especially when they are directly arranged on the front surface, which will destroy the overall aesthetics of the panel.

[0003] Taking proximity sensing as an example, in order to accurately detect the distance directly in front of the panel, the traditional approach is to place the proximity sensing transmitter and receiver forward. However, this approach will undoubtedly increase the complexity of the panel and affect the aesthetics. Some smart switches also use radar distance sensors, which can directly penetrate plastic parts to detect external distances without opening holes on the panel surface. However, this type of sensor is expensive and may have certain limitations in practical applications. Utility Model Content

[0029] The present invention is described in detail below with reference to the accompanying drawings and specific embodiments.

[0030] The utility model provides an intelligent switch panel, such as Figures 1 to 6 As shown, it includes a control module 1 located at the front side and a power module 2 located at the rear side. The utility model does not limit the connection method between the power module 2 and the control module 1. Preferably, they are detachably connected through a snap-on structure and electrically connected. This connection method facilitates the removal and installation of the two. The control module 1 has a front shell 11, on which a PCB main board 13 and a proximity sensor 15 electrically connected to the PCB main board 13 are arranged.

[0031] The key point of the present utility model is that Figure 3 and Figure 4As shown, the bottom of the front shell 11 is provided with a downwardly inclined installation window 111, and the angle between the installation window 111 and the front surface of the front shell 11 is, and after the proximity sensor 15 is fixed in the installation window 111, the angle between it and the front surface of the front shell 11 is 0°<α<90°, that is, the proximity sensor 15 is not perpendicular to the front surface of the intelligent switch panel and the ground. The transmitting end and the receiving end of the proximity sensor 15 face the outside of the front shell 11, and the transmitting end and the receiving end can send and receive photoelectric signals through the installation window 111.

[0032] In the application process, the installation height of the intelligent switch panel on the wall is usually 1.2m. After the above intelligent switch panel is installed on the wall (such as Figure 7 The inclined proximity sensor 15 can form a detection distance of 0.5m in front of it (as shown in point a). Figure 7 The sensor is not placed directly in front of the camera, but can detect the distance directly in front of the camera.

[0033] The shape of the installation window 111 on the front shell 11 of the utility model is designed to be compatible with the shape of the proximity sensor 15. In this embodiment, the shape of the installation window 111 is rectangular. In order to further optimize the performance of the proximity sensor 15 and improve the detection accuracy, as Figure 5 and Figure 6 As shown, the installation window 111 is provided with a partition bar 112. When the proximity sensor 15 is installed on the installation window 111, its transmitting area and receiving area can be effectively separated by the partition bar 112, preventing the photoelectric signal of the transmitting area from interfering with the receiving area, thereby improving the receiving sensitivity and accuracy of the receiving area to the external photoelectric signal. At the same time, the provision of the partition bar 112 also helps to maintain the stability and reliability of the sensor and prolong its service life.

[0034] As a further improvement of the structure, Figure 5 and Figure 6 As shown, a mounting groove 113 is provided on the outside of the mounting window 111 on the front shell 11, and a protective lens 114 is provided in the mounting groove 113. The protective lens 114 can effectively protect the transmitting end and the receiving end of the proximity sensor 15 from external dust, dirt or other impurities. At the same time, the protective lens 114 also has excellent light transmission performance, ensuring that the transmitting end of the proximity sensor 15 can smoothly send photoelectric signals through the lens, and the receiving end can also accurately receive photoelectric signals from the outside.

[0035] The proximity sensor 15 used in this embodiment is an infrared sensor, which detects the approach of an object by emitting infrared light and receiving reflected light. It has the advantages of high sensitivity, fast response speed, strong anti-interference ability, etc. It can accurately detect objects in front of the panel and provide a stable and reliable proximity sensing function for the intelligent switch panel. In addition, infrared sensors are more economical and practical than radar sensors, which can reduce the manufacturing cost of the product.

[0036] Key References Figure 2 The control module 1 also includes a fixing seat 12 and a keypad 14. The fixing seat 12 is snap-fitted to the front shell 11. This design is simple and firm, and can ensure that the PCB mainboard 13 is stably installed on the front shell 11. Of course, in order to meet different production requirements, the fixing method of the fixing seat 12 and the front shell 11 is not limited to snap-fitting, and other reliable fixing methods such as screw connection can also be selected. The keypad 14, as an important component of the control module 1, is located on the fixing seat 12. When the keypad 14 is covered on the fixing seat 12, it can not only effectively protect the internal components such as the PCB mainboard 13 and the proximity sensor 15, but also completely cover the front surface of the front shell 11, thereby realizing the hidden design of the proximity sensor 15.

[0037] like Figure 2 and Figure 5 As shown, the fixing base 12 is provided with a relief slope 121 at a position corresponding to the proximity sensor 15, and the relief slope 121 is provided for the back of the proximity sensor 15 to abut against, so as to provide a stable abutting support. The inclination angle of the relief slope 121 is the same as the inclination angle of the installation window 111 and the proximity sensor 15. Such a design not only ensures the stability and accuracy of the proximity sensor 15 during the installation process, but also effectively prevents performance degradation or damage caused by improper installation.
