Description

Technical Field

[0001] The utility model relates to the technical field of key switches, in particular to a planar intelligent wall switch. Background Art

[0002] Existing flat smart wall switches generally include a mounting base box, a micro switch disposed on the mounting base box, and at least one key panel rotatably disposed on the mounting base box. The micro switch is pressed by the key panel to disconnect or conduct the micro switch to achieve switch control. In order to ensure thinness and lightness, existing flat smart wall switches use micro switches with smaller key travel. During installation or use, the internal structure of the mounting base box is easily deformed into the wall hole by external forces, causing the micro switch to sink, resulting in the key panel failing to press the micro switch, and the flat smart wall switch has a high risk of failure. Utility Model Content

[0003] In order to overcome the disadvantage of high failure risk of the planar intelligent wall switch in the prior art, the utility model provides a planar intelligent wall switch, which can reduce the failure risk of the planar intelligent wall switch.

[0004] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a flat intelligent wall switch, comprising an installation base box, a micro switch arranged in the installation base box and at least one key plate rotatably arranged in the installation base box, the key plate presses the micro switch to disconnect or conduct it, and the micro switch generates a rebound force resisting the pressing when pressed to reset the key plate after the pressing is released, the installation base box is provided with a stop surface inclined toward the inside of the installation base box, and the key plate is provided with an abutment surface corresponding to the stop surface, and there is a space between the abutment surface and the stop surface for the key plate to press, so as to provide a movable margin for the key plate to trigger the micro switch.

[0005] In the above technical solution, the keypad rotates toward the side close to the installation base box and triggers the micro switch to control the disconnection or conduction of the micro switch. The stop surface is tilted toward the inside of the installation base box, so that there is a space for the keypad to press between the abutting surface and the stop surface, so as to provide a margin of activity for the keypad to trigger the micro switch, increase the keypad stroke, so that when the micro switch sinks due to the deformation of the internal structure of the installation base box into the wall hole, the keypad can still trigger the micro switch, which can reduce the risk of failure of the flat intelligent wall switch.

[0006] The utility model is further configured as follows: the stop surface and the abutting surface on the key plate that is not pressed form an angle A, and the angle A satisfies: 0.3°≤A≤1.4°.

[0007] In the above technical solution: when the angle A is ≥ 0.3°, the movable space between the stop surface and the abutting surface is large enough to provide a margin for the keypad to trigger the micro switch, which can reduce the risk of failure of the flat smart wall switch; if the angle A is less than 0.3°, the movable space between the stop surface and the abutting surface is too small, and the risk of the keypad failing to press the micro switch is still relatively high; when the angle A is greater than 1.4°, the micro switch will be over-pressed when the keypad is pressed downward, causing the micro switch to be damaged. Therefore, when the angle A satisfies 0.3°≤A≤1.4°, the keypad can have enough travel to offset the sinking of the micro switch caused by the deformation of the internal structure of the installation base box into the wall hole, thereby reducing the risk of failure of the flat smart wall switch.

[0008] The utility model is further configured as follows: the installation base box includes a base box body and a mounting portion formed by extending from the upper end of the base box body toward the periphery, a first reinforcing rib is arranged on the side of the mounting portion facing the key board, and the stop surface is the upper end surface of the first reinforcing rib.

[0009] In the above technical solution, the strength of the installation part can be increased by the first reinforcing rib, so that the planar intelligent wall switch will not produce excessive deformation during installation, which can prevent the micro switch from sinking and reduce the risk of failure of the planar intelligent wall switch.

[0010] The utility model is further configured as follows: the mounting portion is provided with a mounting hole, the mounting portion is provided with a second reinforcing rib on the side facing away from the key plate, and the second reinforcing rib at least surrounds a portion of the outer circumference of the mounting hole.

[0011] In the above technical solution, the second reinforcing rib can increase the strength of the area near the installation hole, so that the flat smart wall switch will not be deformed too much during installation, which can prevent the micro switch from sinking and reduce the risk of failure of the flat smart wall switch. At the same time, it can also prevent the installation bottom box from deforming, causing the installation bottom box to jam the keypad.

[0012] The utility model is further configured as follows: one end of the keypad is rotatably connected to the mounting base box, the other end is provided with a hook, the mounting base box is provided with a slot corresponding to the hook, and the hook at least partially extends into the slot to limit the rotation angle of the keypad away from the mounting base box.

[0013] In the above technical solution, the hook is used to limit the rotation angle of the keypad away from the mounting bottom box, so as to prevent the keypad from being lifted during use. When the keypad needs to be disassembled, the hook can be disengaged from the slot to complete the disassembly of the keypad.

[0014] The utility model is further configured as follows: a mounting frame is provided on the key panel, a buckle is provided on the mounting base box, and a cylindrical protrusion for engaging with the buckle is provided on the mounting frame, and the key panel rotates relative to the cylindrical protrusion through the buckle and realizes relative rotation with the mounting base box.

[0015] In the above technical solution, the key panel can be rotatably connected relative to the mounting base box and can be detached relative to the mounting base box by engaging the buckle with the cylindrical protrusion. When the key panel is damaged, only the key panel needs to be replaced, thereby optimizing the product structure.

[0016] The utility model is further configured as follows: a pressure plate and a circuit board located below the keypad are sequentially arranged in the installation base box, the circuit board is fixed to the installation base box through the pressure plate, the micro switch is arranged on the installation base box through the circuit board, an avoidance hole is arranged on the pressure plate, and a top column is arranged on the abutting surface, and when the keypad is pressed, the top column passes through the avoidance hole and presses the micro switch to disconnect or connect the micro switch.

[0017] The utility model is further configured as follows: at least two limiting posts are arranged in the installation base box, and limiting holes adapted to the limiting posts are correspondingly arranged on the circuit board, and the limiting posts are inserted into the limiting holes to fix the circuit board.

[0018] In the above technical solution: when installing the circuit board, the circuit board is positioned by inserting the limiting pillars into the limiting holes, thereby ensuring the determination of the assembly position of the circuit board and improving the installation efficiency of the circuit board.

[0019] The utility model is further configured as follows: a light emitting component is disposed on the circuit board, a light guiding component is disposed on the key board, and a light guiding hole for transmitting light to the light guiding component is correspondingly disposed on the pressing plate.

[0020] In the above technical solution, the light-emitting element plays an indicating role, which can avoid the situation where the user has to stretch out his hand to constantly grope for the panel in the dark, thereby greatly improving the user's experience.

[0021] The utility model is further configured as follows: at least two key panels are arranged on the installation base box at intervals, the key panels are provided with limiting protrusions, and the installation base box is correspondingly provided with limiting grooves adapted to the limiting protrusions, and the limiting protrusions and the limiting grooves cooperate to limit the setting direction of the key panels.

[0022] In the above technical solution, the limiting protrusion cooperates with the limiting groove to limit the setting direction of the key panel, so that during pressing the key panel, the key panel can be prevented from shifting in the setting direction, causing the key panels to scratch each other or even cause linkage problems.

[0023] The beneficial effect of the utility model is that the stroke of the keypad is increased so that when the microswitch sinks due to the deformation of the internal structure of the installation base box into the wall hole, the keypad can still trigger the microswitch, thereby reducing the risk of failure of the flat intelligent wall switch.

DETAILED DESCRIPTION

[0035] In the description of this embodiment, it should be noted that if the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", "front", "back", etc. appear, the orientation or position relationship indicated is based on the orientation or position relationship shown in the accompanying drawings, which is only for the convenience of describing the utility model and simplifying the description, and does not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operate in a specific orientation. Therefore, it cannot be understood as a limitation on the utility model. In addition, if the terms "first", "second", and "third" appear, they are only used for descriptive purposes and cannot be understood as indicating or implying relative importance.

[0036] The utility model is further described below in conjunction with the accompanying drawings and specific embodiments.

[0037] like Figures 1 to 10 As shown, a planar intelligent wall switch comprises an installation base box 1, a micro switch 31 arranged on the installation base box 1 and at least one key panel 2 rotatably arranged on the installation base box 1, the key panel 2 presses the micro switch 31 to disconnect or connect it, and the micro switch 31 generates a rebound force resisting the pressing when pressed so as to reset the key panel 2 after the pressing is released, the installation base box 1 is provided with a stop surface 111 inclined toward the installation base box 1, and the key panel 2 is provided with an abutment surface 21 corresponding to the stop surface 111, and there is a space between the abutment surface 21 and the stop surface 111 for the key panel 2 to press and move, so as to provide an activity margin for the key panel 2 to trigger the micro switch 31.

[0038] In this embodiment, the keypad 2 rotates toward the side close to the installation base box 1 and triggers the micro switch 31, controlling the disconnection or conduction of the micro switch 31. The stop surface 111 is tilted toward the installation base box 1, so that there is a space for the keypad 2 to press between the abutting surface 21 and the stop surface 111, so as to provide a margin of activity for the keypad 2 to trigger the micro switch 31, increase the stroke of the keypad 2, so that when the micro switch 31 sinks due to the deformation of the internal structure of the installation base box 1 into the wall hole, the keypad 2 can still trigger the micro switch 31, which can reduce the risk of failure of the planar intelligent wall switch.

[0039] In the prior art, in order to make the flat intelligent wall switch thinner and lighter, the original traditional switch is eliminated and a smaller micro switch is used. However, the micro switch has a small stroke. When the micro switch 31 sinks due to the deformation of the internal structure of the installation base box 1 into the wall hole, the space between the key board 2 and the micro switch 31 increases, which may cause the key to fail to trigger the micro switch 31. In this embodiment, while maintaining the thinness of the flat intelligent wall switch, the internal structure of the installation base box 1 is changed to increase the stroke of the key board 2, thereby reducing the risk of failure of the flat intelligent wall switch.

[0040] Specifically, Figure 7 and Fig.10 As shown, the stop surface 111 forms an angle A with the abutting surface 21 on the unpressed keypad 2, and the angle A satisfies: 0.3°≤A≤1.4°. When the angle A≥0.3°, the movable space between the stop surface 111 and the abutting surface 21 is large enough to provide an activity margin for the keypad 2 to trigger the micro switch 31, which can reduce the risk of failure of the planar intelligent wall switch; if the angle A is less than 0.3°, the movable space between the stop surface 111 and the abutting surface 21 is too small, and the risk that the keypad 2 cannot press the micro switch 31 is still relatively large; when the angle A is greater than 1.4°, the micro switch 31 will be pressed excessively when the keypad 2 is pressed downward, causing the micro switch 31 to be damaged. Therefore, when the angle A satisfies 0.3°≤A≤1.4°, the keypad 2 can have enough travel to offset the sinking of the micro switch caused by the deformation of the internal structure of the installation base box 1 into the wall hole, thereby reducing the risk of failure of the planar intelligent wall switch. In addition, the keypad 2 rotates toward the side where the bottom box 1 is installed, and the keypad 2 will reset after being pressed, so as to maintain the flat visual effect of the keypad 2, which is beneficial to improving the appearance of the product.

[0041] Specifically, in this embodiment, the angle A is 0.3°. Of course, in other embodiments, the angle A can be a suitable value such as 0.8° or 1.4°.

[0042] Specifically, Figure 2 and Figure 4 As shown, the installation base box 1 includes a base box body 12 and a mounting portion 13 formed by extending from the upper end of the base box body 12 to the outer periphery, and a first reinforcing rib 11 is provided on the mounting portion 13 facing the keypad 2, and the stop surface 111 is the upper end surface of the first reinforcing rib 11. The first reinforcing rib 11 can increase the strength of the mounting portion 13, so that the flat smart wall switch will not be deformed too much during installation, and the micro switch can be prevented from sinking, thereby reducing the risk of failure of the flat smart wall switch.

[0043] Among them, Fig. 9 As shown, the mounting portion 13 is provided with a mounting hole 131, and a second reinforcing rib is provided on the side of the mounting portion 13 facing away from the keypad 2, and the second reinforcing rib surrounds at least a portion of the outer circumference of the mounting hole 131. The planar intelligent wall switch is fixed to the wall through the mounting hole 131 by a locking member. The second reinforcing rib can increase the strength of the area near the mounting hole 131, so that the planar intelligent wall switch will not be deformed too much during installation, and the micro switch can be prevented from sinking, thereby reducing the risk of failure of the planar intelligent wall switch. At the same time, it can also prevent the installation base box 1 from being deformed, causing the installation base box 1 to jam the keypad 2.

[0044] Generally, the locking member is a screw, and the screw passes through the mounting hole 131 to fix the planar intelligent wall switch on the wall.

[0045] Specifically, Figure 3 , Figure 7 and Figure 8 As shown, one end of the keypad 2 is connected to the mounting base box 1 for rotation, and the other end is provided with a hook 22. The mounting base box 1 is provided with a slot 14 corresponding to the hook 22. The hook 22 at least partially extends into the slot 14 to limit the angle at which the keypad 2 rotates away from the mounting base box 1. The hook 22 limits the angle at which the keypad 2 rotates away from the mounting base box 1, so as to prevent the keypad 2 from being lifted during use. At the same time, when the keypad 2 needs to be disassembled, the hook 22 can be disengaged from the slot 14 to complete the disassembly of the keypad 2.

[0046] Furthermore, if Figure 3 and Fig.10 As shown, the key board 2 is provided with a mounting frame 23, the mounting base box 1 is provided with a buckle 15, and the mounting frame 23 is provided with a cylindrical protrusion 231 for engaging with the buckle 15. The key board 2 is rotated relative to the mounting base box 1 by the buckle 15 relative to the cylindrical protrusion 231. The buckle 15 is engaged with the cylindrical protrusion 231, so that the key board 2 can be rotatably connected with the mounting base box 1 and can be detached relative to the mounting base box 1. When the key board 2 is damaged, only the key board 2 needs to be replaced, thereby optimizing the structure of the product.

[0047] Specifically, Figures 2 to 7 As shown, a pressing plate 4 and a circuit board 3 are sequentially arranged below the key board 2 in the installation base box 1. The circuit board 3 is fixed to the installation base box 1 through the pressing plate 4. The micro switch 31 is arranged on the installation base box 1 through the circuit board 3. The pressing plate 4 is provided with an avoidance hole 41. The abutting surface 21 is provided with a top column 211. When the key board 2 is pressed, the top column 211 passes through the avoidance hole 41 and presses the micro switch 31 to disconnect or conduct the micro switch 31. Specifically, a through hole is provided on the pressing plate 4, and the pressing plate 4 is fixed to the installation base box 1 by passing a self-tapping screw through the through hole.

[0048] Among them, Figure 4 and Figure 6 As shown, at least two limiting posts 16 are provided in the installation base box 1, and limiting holes 32 adapted to the limiting posts 16 are correspondingly provided on the circuit board 3, and the limiting posts 16 are inserted into the limiting holes 32 to fix the circuit board 3. When installing the circuit board 3, the limiting posts 16 are inserted into the limiting holes 32 to position the circuit board 3, thereby ensuring the determination of the assembly position of the circuit board 3 and improving the installation efficiency of the circuit board 3.

[0049] In addition, if Figure 2 , Figure 3 and Figure 5As shown, the circuit board 3 is provided with a light emitting member 33, the key board 2 is provided with a light guide member 24, and the pressing plate 4 is provided with a light guide hole 42 for transmitting light to the light guide member 24. The light emitting member 33 plays an indicating role, which can avoid the situation where the user reaches out and keeps groping for the panel in the dark, greatly improving the user's experience of use.

[0050] Specifically, in this embodiment, the light guide 24 and the key plate 2 are separate structures, and a mounting groove 26 is provided on the key plate 2, and the light guide 24 is tightly matched with the mounting groove 26. The light guide 24 and the key plate 2 are manufactured separately to reduce the manufacturing difficulty. Specifically, in this embodiment, the mounting groove 26 is formed by a convex rib provided on the key plate 2. Of course, in other embodiments, the light guide 24 and the key plate 2 can be an integrally formed structure, which can increase the strength, reduce the installation process, and improve the installation efficiency.

[0051] Specifically, Figure 3 and Figure 4 As shown, at least two keypads 2 are arranged at intervals on the mounting base box 1, and a limiting protrusion 25 is arranged on the keypad 2. A limiting groove 17 adapted to the limiting protrusion 25 is correspondingly arranged on the mounting base box 1, and the limiting protrusion 25 cooperates with the limiting groove 17 to limit the setting direction of the keypad 2. The limiting protrusion 25 cooperates with the limiting groove 17 to limit the setting direction of the keypad 2, so that when the keypad 2 is pressed, the keypad 2 can be prevented from deviating in the setting direction of the keypad 2, which causes the keypads 2 to scratch each other and even cause linkage problems.

[0052] Specifically, if Figure 4 As shown, in this embodiment, the limiting groove 17 includes two parallel protrusions 171 arranged on the key plate 2. When the key plate 2 rotates, the limiting protrusion 25 slides in the limiting groove 17 and abuts against one side of the protrusion 171.

[0053] The specific description of the present invention in the above embodiments is only used to further illustrate the present invention and cannot be understood as limiting the scope of protection of the present invention. Technical engineers in this field may make some non-essential improvements and adjustments to the present invention based on the contents of the above-mentioned utility model, which fall within the scope of protection of the present invention.
