Referring to fig. 1, an opening and closing control box according to an embodiment includes a cover 10, a box 20, a control wheel 30, a control module 40, and a light guide 50.

The panel cover 10 is detachably connected to the box body 20 to form a containing cavity for containing the control module 40 and the light guide plate 50 in the switch control box. The face cover 10 is provided with a clearance groove 10a, and part of the structure of the regulating wheel 30 penetrates out of the face cover 10 from the clearance groove 10a and can rotate relative to the box body 20 so as to utilize the regulating wheel 30 to control the circuit.

Specifically, the regulating wheel 30 is provided with an electrical signal output module, and the electrical signal output module is electrically connected with the control module 40. When the control wheel 30 rotates relative to the box 20, the electrical signal output module outputs a control signal to the control module 40 to implement on-off control, such as adjusting the brightness of a lamp or the volume of a sound playing device.

Referring to fig. 2, in some embodiments, the regulating wheel 30 is connected to the case 20 via a wheel seat 31. Specifically, the wheel seat 31 is annular and has a shaft groove 311. The rotating shaft 30a of the regulating wheel 30 is rotatably matched with the shaft groove 311 on the wheel seat 31, so that the regulating wheel 30 can rotate relative to the wheel seat 31, and the regulation and control requirements of the control module 40 of the switch control box on a control object can be met through the rotation of the regulating wheel 30.

It should be noted that there are various implementations for implementing the adjustment of the brightness or volume of the lamp by the rotation operation of the control wheel 30. For example, in some embodiments, the electrical signal output module can change the magnitude of the output current or the resistance, so that when the regulating wheel 30 rotates at different angles, different control signals are correspondingly output, and the control module 40 implements on-off control. The control mode of the regulating wheel 30 is not limited herein, as long as the electrical signal output module can generate a control signal along with the rotation of the regulating wheel 30 to output to the control module 40, so as to satisfy the circuit control. For example, when the air volume of the fan is controlled by the rotation operation of the regulating wheel 30, the control module 40 may be in communication connection with a control system of the fan, so that the rotation of the regulating wheel 30 enables the electrical signal output module to output a control signal for regulating the air volume, and the control module 40 receives the control signal and then performs corresponding circuit control on the fan.

In this embodiment, the control module 40 includes a PCB or a flexible circuit board, and a switch button electrically connected to the PCB or the flexible circuit board. In the switch control box, the control module 40 includes a control circuit corresponding to a switch key, and the switch key may be a volume key or an air volume key, or may be a key for controlling other electrical appliances such as a lamp or a television, and a control object of the switch key is not limited herein.

The number of the switch keys can be 1 or more than 1. For example, fig. 1 shows a switch control box in which a control module 40 is provided with 2 first switch buttons 41, 1 second switch button 42, and 1 third switch button 43. The control objects of the 2 first switch buttons 41 may be the same or different. Accordingly, the objects to be controlled by the first switch button 41, the second switch button 42, and the third switch button 43 may be the same or different, and the objects to be controlled by the respective switch buttons are not limited herein. For example, in an embodiment, when the switch control box is used to control a lamp, 2 first switch buttons 41 may be used to control the brightness of the lamp, specifically, one of the first switch buttons 41 is used to turn on, and the other first switch button 41 is used to turn off. For another example, in some embodiments, the second switch button 42 is used to control the lamp to be turned off, and the third switch button 43 is used to control the lamp to be turned on.

The switch control box also comprises a mounting structure so as to mount the switch control box in a mounting environment such as a wall or a desk. The installation environment of the switch control box can be other positions, such as a decorative cabinet, and is not limited herein.

The mounting structure may be a metal frame 60, the metal frame 60 may be a semi-enclosed structure, and in some embodiments, the metal frame 60 is a metal sheet bent to a size corresponding to the external size of the case 20.

In some embodiments, the metal shelf 60 and the case 20 are pre-secured by a snap fit. Specifically, the side wall of the metal frame 60 opposite to the box body 20 is provided with a clamping groove 60a, and the outer wall of the box body 20 is provided with a buckle 23 matched with the clamping groove 60a, so that the box body 20 can be quickly fixed to the metal frame 60 through the matching of the buckle 23 and the clamping groove 60 a.

Referring to fig. 1, 3 and 4, the switch control box includes an outer cover plate 70 connected to the metal frame 60, the outer cover plate 70 is provided with a window 71 for exposing the cover 10, so that when the outer cover plate 70 is connected to the metal frame 60, the adjusting wheel 30 or the switch button on the cover 10 can be still operated, and meanwhile, the outer cover plate 70 can cover a mounting gap between the box body 20 and a mounting environment, so that the switch control box is more beautiful in the mounting environment.

It should be noted that the outer cover plate 70 and the metal frame 60 may be connected by a snap connection, or may be fixedly connected by a locking member such as a screw or a bolt. For example, referring to fig. 1, the screw holes 72 are formed in the outer cover 70, the through holes 60b corresponding to the screw holes 72 are formed in the metal frame 60, so that the cover 10 is placed on the case 20 after the metal frame 60 is installed in an installation environment such as a wall, a table, etc. and the case 20 is connected to the metal frame 60, the outer cover 70 is placed on the peripheral side of the cover 10, and locking members such as screws or bolts are inserted through the screw holes 72 and the through holes 60b and fixed to the installation environment.

Continuing to refer to fig. 1, a plurality of lamp beads 44 are arranged in the box body 20, and the plurality of lamp beads 44 are arranged side by side. It should be noted that, the plurality of lamp beads 44 may be separately disposed on the circuit board and installed in the box body 20, and the plurality of lamp beads 44 may also be integrated on the PCB or the flexible circuit board of the control module 40, so as to reduce the occupation of the internal space of the box body 20, so that the switch control box can be made smaller and smaller, and the installation form of the plurality of lamp beads 44 in the box body 20 is not limited herein.

The light guide plate 50 is used for transmitting the light of the lamp beads 44 to the outside of the face cover 10, thereby achieving a control quantity promoting effect. For example, in the process of rotating and adjusting the adjusting wheel 30, the plurality of lamp beads 44 are selectively lighted, specifically, the adjusting wheel 30 rotates by different angles, and the number of the lighted lamp beads 44 is different, so that the lengths of the light bars transmitted out of the face cover 10 through the light guide sheet 50 are different, thereby representing the adjusting state.

Taking the case that the light brightness is adjusted by the adjusting wheel 30 of the switch control box, the light brightness changes along with the rotation of the adjusting wheel 30 relative to the box body 20, and at this time, the quantity change of the lighting of the lamp beads 44 characterizes the light adjusting result. For example, when the light is adjusted to be brightest, all the lamp beads 44 are lit, so that the user can adjust the state according to the length of the light bar of the light guide plate 50.

In some embodiments, the plurality of light beads 44 are in signal connection with the adjusting and controlling wheel 30 through the control module 40, for example, the number of the lighted light beads 44 corresponds to the rotation angle of the adjusting and controlling wheel 30, that is, the light beads 44 are selectively lighted by rotating the adjusting and controlling wheel 30, which can be implemented by such a structure. For example: an angle sensor is arranged in the box body 20, is in signal connection with the control module 40, and is used for detecting the rotation angle or the position of the regulating and controlling wheel 30. In the rotation process of the regulating wheel 30, the angle sensor generates a detection signal according to the detected rotation angle or rotation position of the regulating wheel 30, and feeds the detection signal back to the control module 40, so that the control module 40 controls the lamp bead 44 to be selectively turned on. That is, during the rotation of the regulating wheel 30, the lamp bead 44 is correspondingly lighted, thereby representing the regulating effect of the regulating wheel 30. This kind of mode that adopts the light guide plate to come the representation regulation state with the light derivation that lamp pearl 44 sent, it is directly perceived promptly, and lamp pearl 44 can enrich the result of use of on-off control box after lighting.

Of course, the rotation of the regulating wheel 30 can also be achieved by changing the current or the resistance, so that the lamp beads 44 are correspondingly illuminated. The lighting pattern of the lamp bead 44 is not limited herein.

Referring to fig. 1 and 2, a clamping groove 10b is formed in the surface cover 10, one side of the light guide plate 50 is opposite to the lamp bead 44, and the other side of the light guide plate 50 is clamped in the clamping groove 10b, so that when the lamp bead 44 emits light, the light guide plate 50 guides the light to emit out of the surface cover 10.

Further, the light guide sheet 50 is provided with a plurality of grooves 50a, the plurality of grooves 50a divide the light guide sheet 50 into a plurality of light guide units 51 arranged at intervals, each light guide unit 51 corresponds to one lamp bead 44, so that when the lamp beads 44 emit light, the light is guided out of the light emitting surface 50b of the light guide sheet 50 from the corresponding light guide unit 51. It should be noted that the light emitting surface 50b of the light guiding sheet 50 is a surface facing away from the lamp bead 44, and when the light guiding sheet 50 is clamped in the clamping groove 10b, the light emitting surface 50b of the light guiding sheet 50 is exposed out of the face cover 10 to guide the light beam out. Because separated by separating groove 50a between the light guide unit 51 to lamp pearl 44 emergent ray will be derived along corresponding light guide unit 51, and the light beam diffusion can not appear, influences the suggestion effect.

One side of the light guide sheet 50 close to the lamp beads 44 is provided with a plurality of grooves 51a, and the plurality of grooves 51a correspond to the plurality of light guide units 51 one to one. As shown in fig. 5, the plurality of beads 44 are correspondingly accommodated in the plurality of grooves 51a, so that when the beads 44 emit light, the light emitted from the beads 44 will be emitted out of the surface cover 10 along the corresponding light guide unit 51, so as to clearly present the light stripe formed by the lit beads 44, and further, a user can intuitively know the regulation state of the regulation wheel 30 on the regulation object according to the length of the light stripe.

As shown in fig. 1, 2 and 5, the cover 10 and the box 20 can rotate relatively, that is, the cover 10 and the box 20 are rotatably connected. It should be noted that the rotation angle of the face cover 10 relative to the box body 20 may be less than 5 °, so as to avoid that the rotation angle of the face cover 10 relative to the box body 20 is too large, which is easy to loose, and affects the use effect of the switch control box.

In some embodiments, the face cover 10 is provided with a shaft pin 10c, the case 20 is provided with a fitting groove 21 which is rotatably fitted with the shaft pin 10c, when the face cover 10 is fitted with the case 20, the shaft pin 10c is rotatably fitted with the fitting groove 21, and the periphery of the face cover 10 is spaced from the periphery of the case 20, so that the face cover 10 can rotate relative to the case 20 when the face cover 10 is pressed.

In this embodiment, the cover 10 contacts with a switch button on the control module 40 disposed in the box body 20, for example, as shown in fig. 1 and 5, the cover 10 contacts with the second switch button 42, so that when the side of the cover 10 corresponding to the second switch button 42 is pressed, the cover 10 can press the second switch button 42, thereby implementing the switch control.

In some embodiments, the pre-fixing between the cover 10 and the box 20 may be achieved by a snap-fit structure, and it should be noted that the pre-fixing does not affect the rotation of the cover 10 relative to the box 20. For example, the side wall of the case body 20 is provided with a clamping groove 24, and the clamping groove 24 can be clamped into the clamping groove 24, so that the clamping groove 24 can move in the clamping groove 24, when the face cover 10 is pressed to perform on-off control, the rotation of the face cover 10 relative to the case body 20 cannot be interfered by the cooperation of the clamping groove 24 and the clamping groove 10, and the face cover 10 and the case body 20 keep a certain assembling state by the cooperation of the clamping groove 24 and the clamping groove 10. Specifically, in this state, the face cover 10 is in contact with the second switch key 42, so that when the user presses the second switch key 42 against the face cover 10, the second switch key 42 will be triggered to implement the corresponding switch control.

Referring to fig. 1, 2 and 5, the wheel seat 31 of the regulating wheel 30 is rotatably engaged with the box body 20, and the wheel seat 31 contacts with the third switch button 43, when the regulating wheel 30 is pressed, the regulating wheel 30 forces the wheel seat 31 to rotate relative to the box body 20 and presses the third switch button 43, so as to realize the switch control.

In some embodiments, one side of the wheel seat 31 contacts the third switch button 43, and the other side is provided with a rotation connection portion 312, and the rotation connection portion 312 may be a rotation shaft or a shaft pin. The box body 20 is provided with a support body 22 therein, the support body 22 is provided with a matching part 22a which is rotatably matched with the rotating connection part 312, and the matching part 22a can be a shaft hole, or a U-shaped groove or an arc-shaped groove. It is only necessary that the rotation connection portion 312 is rotatably engaged with the engagement portion 22a of the support 22, so that when the adjustment wheel 30 is pressed, the wheel seat 31 can press and trigger the third switch button 43.

In some embodiments, a human body pyroelectric infrared sensor 80 is further disposed in the case body 20 of the switch control box for detecting a thermal sensing signal source for switch control. For example, when the switch control box is applied to a lamp, after the human pyroelectric infrared sensor 80 detects that a user enters a detection range, a control instruction is issued, so that the control module 40 turns on the lamp. The application scenario and the number of the on-off control of the human pyroelectric infrared sensor 80 are not limited herein.

In some embodiments, the human pyroelectric infrared sensor 80 has a plurality of human pyroelectric infrared sensors 80, so that the detection of the thermal sensing signal by the plurality of human pyroelectric infrared sensors 80 satisfies the requirement that the control module 40 performs different controls on the object to be controlled.

The following description will be given of an application scenario of the pyroelectric infrared sensor 80, taking only 2 human bodies as an example.

Referring to fig. 1, the 2 pyroelectric infrared sensors 80 may be arranged side by side, and in other embodiments, may be arranged at different positions of the control module 40, so long as they can detect infrared heat through the front cover 10.

As the 2 human body pyroelectric infrared sensors 80 are arranged at different positions, in the moving process of a user, the 2 human body pyroelectric infrared sensors 80 respectively detect human body thermal sensing signals in sequence, and therefore a switch regulation mode is defined according to the sequence of the thermal sensing signals detected by the 2 human body pyroelectric infrared sensors 80. For convenience of understanding, the 2 pyroelectric infrared sensors 80 are respectively referred to as a "first sensor" and a "second sensor", and the corresponding detected thermal sensing signals are respectively referred to as a "first signal" and a "second signal", wherein the control module 40 controls the light to be brightened when the first sensor detects the first signal and the second sensor detects the second signal, and correspondingly, the control module 40 controls the light to be darkened when the second sensor detects the second signal and the first sensor detects the first signal.

It should be noted that the regulation mode of the control module 40 is not limited to the above-mentioned example, and may also be adapted to other situations where the object to be regulated is regulated in the forward direction and the reverse direction, for example, the volume of the sound playing device or the air volume of the fan is regulated, and is not limited herein.

Referring to fig. 1, the human pyroelectric infrared sensor 80 may be integrated on a circuit board of the control module 40, so that the electrical components in the switch control box are more compact, convenient to set and easy to assemble. In other embodiments, the human pyroelectric infrared sensor 80 may also be independently disposed in the box body 20, and only needs to satisfy the functional requirement of human infrared detection, which is not limited herein.

The face cover 10 has a transmissive area for the pyroelectric infrared sensor 80 to detect the thermal signal source.

As shown in fig. 6 and 7, the face cover 10 includes a face shell 11 and a framework 12, wherein the face shell 11 is made of High Density Polyethylene (HDPE) material, and the face shell 11 of the face cover 10 is made of the HDPE material, which not only meets the requirement of the human pyroelectric infrared sensor 80 for thermal sensing, but also prevents the user from seeing the contour of the transmission area through the face shell 11 with naked eyes, specifically, the face shell 11 is covered on the framework 12, and the face shell 11 will form an integral appearance surface, and the integral aesthetic feeling of the appearance of the face cover 10 will not be affected by the observation of the transmission area.

In this embodiment, the material of the skeleton 12 may be Polycarbonate (PC) material. So as to form a support for the face shell 11 by the skeleton 12 to prevent the face shell 11 from being deformed.

When the face shell 11 is made of the high-density polyethylene material, the just-formed face shell 11 is easily deformed and shrunk because the face shell 11 is made of the high-density polyethylene material and the high-density polyethylene material needs to be subjected to hot melting to form the face shell 11 in a mold, and the face shell 11 is easily deformed and shrunk due to shrinkage of the material after the face shell 11 is formed and in the process of temperature return.

As shown in fig. 8 and 9, the surface shell 11 is connected to the frame 12 by a snap connection, so that the surface shell 11 can be tightly fixed to the frame 12 by using the shrinkage of the surface shell 11 during the process of returning to the temperature, and accordingly, the frame 12 can form a good support for the surface shell 11, thereby preventing the surface shell 11 from deforming. Specifically, the face shell 11 is provided with the clamping groove 111, and the framework 12 is provided with the buckle 122 matched with the clamping groove 111, so that the face shell 11 can be directly buckled on the framework 12 after being taken out from the thermoplastic mold, the buckle connection stability between the face shell 11 and the framework 12 is enhanced by utilizing the contraction force of cooling and shrinking of the face shell 11, and the face shell 11 is not easily deformed under the support of the framework 12, so that the overall appearance aesthetic feeling of the face cover 10 is maintained, and the overall surface texture of the switch control box is improved.

Furthermore, the wall thickness of the face shell 11 is uniform, that is, the thickness of the material is consistent when the face shell 11 is formed by hot molding, so that the shrinkage deformation of the outer surface of the face shell 11 caused by the local thickness difference is prevented, and the whole aesthetic feeling is not influenced. Although the thickness of the portion where the face shell 11 and the frame 12 are snap-fitted is different from that of other portions, the structure of the face shell 11 for snap-fitting occupies a very small amount of the entire structure of the face shell 11, and even if the face shell is deformed, the influence on the appearance and the texture of the entire face shell 11 is negligible, and the portion where the face shell 11 and the frame 12 are snap-coupled is less likely to be deformed due to shrinkage under the supporting action of the frame 12.

Referring to fig. 6, in the embodiment that the face cover 10 includes the face shell 11 and the frame 12, a first through hole 11a is formed at a position of the face shell 11 corresponding to the adjusting wheel 30, a second through hole 12a is formed at a position of the frame 12 corresponding to the adjusting wheel 30, and the first through hole 11a corresponds to the second through hole 12a to form an empty avoiding groove 10a for the adjusting wheel 30 to be exposed outside the face shell 11, so as to perform on-off control through the adjusting wheel 30.

Referring to fig. 7 and 8, a notch 121 is formed in the frame 12, a position of the notch 121 on the frame 12 corresponds to the human pyroelectric infrared sensor 80, and when the face shell 11 is connected to the frame 12, a transmission region is formed by a part of the structure of the face shell 11 covering the notch 121, that is, the notch 121 is arranged so that the human pyroelectric infrared sensor 80 can detect a thermal sensing signal source through the face shell 11 to meet the thermal sensing control requirement of the switch control box.

The ribs 12c corresponding to the first switch button 41 and the second switch button 42 are disposed on the inner side of the frame 12, and the ribs 12c are in corresponding contact with the corresponding switch buttons, so that when the face cover 10 is pressed to rotate relative to the case 20, the corresponding switch buttons can be pressed by the ribs 12c on the frame 12, and on-off control is realized.

As shown in fig. 6 and 7, in some embodiments, the clamping groove 10b on the face cover 10 is communicated with the clearance groove 10a, the clamping groove 10b divides the face cover 10 into a first pressing portion 101 and a second pressing portion 102, the first pressing portion 101 contacts with one of the 2 first switch keys 41, and the second pressing portion 102 contacts with another of the 2 first switch keys 41, so that the first pressing portion 101 and the second pressing portion 102 can independently perform on-off control.

It should be noted that in the embodiment where the face cover 10 includes the face shell 11 and the skeleton 12, the clip groove 10b on the face cover 10 will penetrate through the face shell 11 and the skeleton 12. Specifically, the panel shell 11 is formed with a first slot 11b, the framework 12 is formed with a second slot 12b corresponding to the first slot 11b, and the first slot 11b and the second slot 12b form the clamping groove 10b, that is, when the light guide sheet 50 is clamped in the clamping groove 10b, the light guide sheet 50 is clamped in the first slot 11b, and the light guide sheet 50 is also clamped in the second slot 12b, so that the light guide sheet 50 can transmit light emitted by the lamp beads 44 located in the box body 20 to one side of the panel shell 11, thereby forming a good luminous efficiency regulation and control prompt effect.

As shown in fig. 6, the first slot 11b and the second slot 12b are disposed such that the panel 11 and the frame 12 form a first pressing portion 101 and a second pressing portion 102, which are independent of each other, and then when the first pressing portion 101 is pressed, the second pressing portion 102 is not interfered, accordingly, when the second pressing portion 102 is pressed, the first pressing portion 101 is not interfered, and thus the first switch key 41 disposed correspondingly can be respectively pressed by the first pressing portion 101 and the second pressing portion 102.
