[0032] Example 1

[0033] Reference Figures 1 to 8 This embodiment provides a non-contact intelligent control switch device, including:

[0034] The switch assembly 100 includes a housing 101 and a refractive element 102 disposed on one side of the housing 101. The housing 101 is provided with a sensing element 103. The housing 101 is provided with an imaging screen 104. The imaging screen 104 is provided with operation buttons 105. The imaging screen 104 is projected onto an imaging plane 106 through the refractive element 102. A virtual button 107 is displayed on the imaging plane 106.

[0035] The cross section of the shell 101 is triangular, the imaging plane 106 is placed vertically, and a plug interface 108 is provided at the back of the shell 101 , and a plug connector 200 is connected to the plug interface 108 .

[0036] The prior art with publication number CN111338098A provides a technical basis for the formation of an imaging plane. On this basis, the present invention adds a virtual button 107 on the imaging plane, and identifies which virtual button is pressed through the sensor 103, and triggers the switching action of the PLC accordingly, which is then transmitted to the actuator 400 such as a relay switching action. Furthermore, the sensor 103 can be an airbar, and the main control module 300 is a PLC.

[0037] Structurally, the imaging plane 106 is not in contact with the refractive element 102 and the housing 101 . Therefore, when the finger touches the virtual key 107 for control, the human body does not need to have any direct contact with the entire device, thus avoiding the risk of electric shock.

[0038] The switch assembly 105 is connected to the main control module 300 via the plug connector 200 , and the main control module 300 is connected to the actuator 400 to access the device circuit 500 for control.

[0039] The size of the protection end 201 is larger than that of the insertion end 202. When in use, the insertion end 202 is inserted into the plug port 108, and the protection end 201 is outside the housing 101. The protection end 201 also serves as a limit.

[0040] The outer shell of the insertion end 202 is insulated, and the conductive wire passes through the protection end 201 and the insertion end 202 and is connected to the conductive contact 203c.

[0041] The plug port 108 is consistent in size with the insertion end 202 .

[0042] The beveled groove 203 d is used to fix the plug connector 200 .

[0043] A receiving groove 600 is provided on the inner side of the plug interface 108, and a conductive member 601, a dustproof member 602 and a hanging plate 603 are provided in the receiving groove 600. The dustproof member 602 includes an arc plate 602a, and a first gear tooth 602b is provided on the outer side of the arc plate 602a. A gear plate 601a is provided on the conductive member 601, and the first gear tooth 602b is meshed with the gear plate 601a.

[0044] The transmission ratio of the first gear tooth 602b and the gear plate 601a is 2:1.

[0045] When the first gear tooth 602b rotates 90°, the gear plate 601a is driven to rotate to 45°.

[0046] The conductive member 601 includes a first rotating shaft 601b, a block 601c is arranged on the first rotating shaft 601b, gear plates 601a are arranged at both ends of the first rotating shaft 601b, a conductive touch plate 601d is arranged on one side of the block 601c, and a connecting line 601e is arranged on the other side of the block 601c, and the conductive touch plate 601d and the connecting line 601e are electrically connected.

[0047] The connecting wire 601e is a flexible wire, and the connecting wire 601e is connected to the control board of the switch assembly 100 .

[0048] The dustproof member 602 includes a second rotating shaft 602c, a first baffle 602d is disposed on the second rotating shaft 602c, and arc plates 602a are disposed at both ends of the second rotating shaft 602c.

[0049] A third rotating shaft 603 a is disposed on the hanging plate 603 , and the third rotating shaft 603 a is rotatably connected to the side wall of the receiving groove 600 .

[0050] Specifically, the second rotating shaft 602c and the first rotating shaft 601b are both rotatably connected to the side wall of the accommodating groove 600, and the third rotating shaft 603a is arranged above and near the plug interface 108, so that the hanging plate 603 is suspended from top to bottom under the action of gravity and blocked at the plug interface 108; the second rotating shaft 602c is arranged below and near the plug interface 108, and under the gear connection, the first baffle 602d is vertically upward to block the plug interface 108, and together block the plug interface 108.

[0051] Fixing plates 101a are provided on both sides of the back of the housing 101 for fixing the housing 101 in the electrical cabinet so that the imaging plane 106 remains vertical for easy operation.

[0052] A vortex spring is disposed at the end of the first rotating shaft 601 b so that the side surface of the lower block 601 c is aligned with the plug-in port 108 in an initial state, and the first baffle 602 d is vertically disposed upward at the plug-in port 108 .

[0053] Specifically, the installation process of the plug connector 200 is to insert the plug connector 200 into the plug interface 108. First, the plug connector 200 pushes the first baffle 602d and the hanging plate 603 to flip inward, and the first baffle 602d flips about 90°. At the same time, the block 601c is driven to rotate about 45°, so that one corner of the block 601c faces the plug interface 108, corresponding to the triangular groove 203. Continue to insert the plug connector 200, so that the corner part of the block 601c and the conductive contact plate 601d are placed in the triangular groove 203, and the conductive contact 203c contacts the conductive contact plate 601d to form conduction.

[0054] The hanging plate 603 rests in the beveled groove 203d under the action of gravity, thereby fixing the plug connector 200.

[0055] Furthermore, in the present invention, a push-pull thin card is provided on the protective end 201, which is used to push the push-pull thin card when unlocking is required, so that the hanging plate 603 is lifted up, and the plug connector 200 is released from fixation. It should be noted that the width of the push-pull thin card can be limited, and a thin groove corresponding to the push-pull thin card can be provided at the plug interface 108, and the push-pull thin card is in the thin groove to avoid leaving too many gaps.

[0056] It will be appreciated that in the development of any actual implementation, as in any engineering or design project, numerous implementation-specific decisions may be made. Such a development effort may be complex and time-consuming, but will be a routine task of design, fabrication, and production for those of ordinary skill having the benefit of this disclosure without undue experimentation.

[0057] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present invention, which should all be included in the scope of the claims of the present invention.
