Description

[Technical Field]

[0001] This utility model relates to a smart switch with a screen. [Background Technology]

[0002] With the development of smart homes, smart switches with screens are widely used in various scenarios because they combine the functions of visual parameter adjustment and convenient control.

[0003] Existing smart switches with screens, such as the integrated control panel with a switch disclosed in CN221327345U, include a base plate, PCB board, mounting bracket, panel assembly, and display screen. In this type of switch with a screen, each component is designed for a specific number of keys, such as a four-key PCB board, resulting in a fixed structure and poor versatility. If manufacturers want to provide products with different specifications such as one-key, two-key, and three-key switches, they must develop a separate mold for each number of keys to manufacture the matching mounting bracket, panel, and other structural components, and stock various specifications of support plates, partitions, and other parts. This undoubtedly significantly increases mold development costs, production costs, and material warehousing and management costs, lacking flexibility.

[0004] Therefore, this utility model was created based on the above-mentioned shortcomings. [Utility Model Content]

Detailed Implementation Methods

[0027] The present invention will be further described below with reference to the accompanying drawings:

[0028] like Figures 1 to 6As shown, a smart switch with a screen includes a base 1. A switching power supply PCB board 2 is housed within the base 1, converting input AC mains power into low-voltage DC power required by the main control circuit. The switching power supply PCB board 2 has a first conductive part 21. Above the switching power supply PCB board 2 is a partition 3, and above the partition 3 is a screen control PCB board 4. The partition 3 separates strong and weak currents and provides mechanical support, and has a socket 31. The screen control PCB board 4 has a display screen 41, and its back side also has a second conductive part 42. During installation, the second conductive part 42 passes downwards through the socket 31 of the partition 3 and electrically connects with the first conductive part 21, thereby simultaneously achieving power transmission and signal communication. Above the screen control PCB board 4 is a support plate 5 that engages with the base 1, pressing the screen control PCB board 4, the partition 3, and the switching power supply PCB board 2 firmly within the base 1. A button inner plate 6 is hinged to the support plate 5. The button inner plate 6 is covered with a button panel 7 that can move the button inner plate 6 to touch the screen and control the switching elements on the PCB board 4. The button inner plate 6 has a first display through hole 61. The support plate 5 has a second display through hole 51 located above the display screen 41 and connected to the first display through hole 61. The button panel 7 has an observation area 71 for observing the display screen 41 through the first display through hole 61 and the second display through hole 51. The observation area 71 has a display glass, which corresponds to the first display through hole 61 of the button inner plate 6. Users can view the content of the display screen 41 through the display glass, the first display through hole 61 and the second display through hole 51. The support plate 5 has a connecting hole 52. The button inner plate 6 has a top pressure post 62 that can press the switching elements on the PCB board 4 through the connecting hole 52 when the button panel 7 is pressed. In this invention, the base, support plate, partition, switching power supply PCB board, and button inner liner are all designed as universal standard parts. By setting universal sockets and multiple connecting holes and top pressure posts distributed around the display through holes, this structure can be adapted to screen control PCB boards with different numbers of switching elements, such as supporting one to four buttons. When it is necessary to produce products with different numbers of buttons, such as two buttons, only the screen control PCB board 4 and the button panel 7 need to be replaced. Specifically, the original four-button screen control PCB board is replaced with a two-button PCB board with only two switching elements, and a corresponding two-button button panel is installed. Pressing the "Light 1" and "Light 2" markings on the button panel 7 will press the tactile switch of the two-button PCB board corresponding to the top pressure post 62. The other two top pressure posts 62 do not have corresponding tactile switches, so they only pass through the connecting hole 52 but do not have a pressing action, which does not affect the use. The display screen 41 only displays the status of two devices, realizing the two-button control function.Since the connector of partition 3 is universal, the second conductive part 42 of the new PCB board can still be smoothly connected to the first conductive part 21. The main structural components such as base 1, partition 3, bracket plate 5, and button inner lining plate 6 do not need any modification, which greatly improves the versatility of the product, greatly reduces the types of materials, and reduces the costs of mold development, production management and warehousing.

[0029] Specifically, the first display through-hole 61 is located in the middle of the button inner liner plate 6, and multiple top pressure posts 62 are evenly distributed around the first display through-hole 61. The second display through-hole 51 is located in the middle of the bracket plate 5, and multiple connecting holes 52 are evenly distributed around the second display through-hole 51. Specifically, there are four top pressure posts 62 and four connecting holes 52. This design can be adapted to 1-4 button screen control PCB boards 4. For example, when using a 1-button screen control PCB board, only one top pressure post and the corresponding connecting hole 52 need to be used, and the remaining connecting holes 52 can be reserved without replacing the bracket plate 5 and the button inner liner plate 6.

[0030] Furthermore, the support plate 5 is provided with a reset device 8 located at the edge of the connecting hole 52, which can push the button inner liner plate 6 back to its original position after the button panel 7 is pressed. This invention, through the reset device 8, ensures that the button inner liner plate 6 and button panel 7 quickly reset after the button is pressed, avoiding jamming and unevenness, resulting in better overall integrity and aesthetics.

[0031] Specifically, the reset device 8 is an elastic arm with one end connected to the support plate 5 and the other end extending upward and abutting against the bottom of the button inner liner plate 6. When the user presses the button panel 7, the button inner liner plate 6 swings downward and squeezes the elastic arm; after the button is released, the deformation restoring force of the elastic arm pushes the button inner liner plate 6 upward to reset, ensuring the reliability of the next pressing operation.

[0032] A first locking device 9 is provided between the bracket plate 5 and the screen control PCB board 4 to secure the screen control PCB board 4 to the bracket plate 5, and a second locking device 10 is provided between the base 1 and the bracket plate 5 to lock the bracket plate 5 in place. This invention achieves rapid positioning and fixation of the screen control PCB board 4 through the first locking device 9, and rapid installation and locking of the entire functional module within the base through the second locking device 10. This results in high assembly efficiency and facilitates subsequent maintenance and replacement. Furthermore, the concealed buckle design makes the appearance more concise and aesthetically pleasing.

[0033] Specifically, the first latching device 9 includes a latch 91 on the screen control PCB board 4 and a first latch 92, one end of which can pass through the latch 91 and latch onto the back of the screen control PCB board 4. The latch 91 is located at the edge of the screen control PCB board 4 and has a rectangular groove structure, while the first latch 92 is integrally formed on the bottom surface of the bracket plate 5, and its position corresponds to the latch 91, forming an L-shaped elastic claw structure. During assembly, the free end of the first latch 92 passes through the latch 91 and latches onto the back of the screen control PCB board 4, thereby achieving the latching and fixing of the two.

[0034] Specifically, the second snap-fit ​​device 10 includes a slot 101 on the side wall of the support plate 5 and a second buckle 102 on the inner side wall of the base 1 that can snap into the slot 101. The second buckle 102 is integrally formed on the inner side wall of the base 1, and its position corresponds to the slot 101. It is a "protrusion" structure. During assembly, the support plate 5 is pressed down to the top opening of the base 1, and the second buckle 102 snaps into the slot 101 to lock the support plate 5 and the base 1.

[0035] Specifically, the first conductive part 21 is a pin socket, soldered to the top surface of the switching power supply PCB board, and the second conductive part 42 is a pin that can be inserted into the pin socket, soldered to the bottom surface of the screen control PCB board 4. During assembly, the pin passes through the socket 31 of the partition 3 and is inserted into the pin socket, realizing a quick electrical connection between the two. This allows the switch to be adapted to screen control PCB boards of different specifications without the need to redesign the power connection method.
