Description

Technical Field

[0001] The utility model belongs to the technical field of switch control, and particularly relates to a switch device. Background Art

[0002] Today, with the continuous progress of lighting technology, the switch devices of lamps are becoming increasingly intelligent and diversified. The induction switch devices widely used in the market include human body induction switches, touch switches, infrared induction switches, etc. These switches not only improve the convenience of use but also bring more intelligent experiences to people's lives. However, there is a prominent problem with these existing switch modules, that is, they are all directly powered by the lamps. Although this design simplifies the power supply process, it brings many inconveniences in actual applications. Once the switch module is damaged, users often cannot replace the switch module alone but need to replace it together with the power supply structure, which undoubtedly increases the complexity and cost of maintenance. In addition, if users want to replace other types of switch modules to meet different usage requirements or improve the usage experience, they also need to face the problem of replacing the entire power supply structure. This not only causes waste of resources but also restricts users' personalized choices for switch modules. Therefore, the existing designs of lamp switch devices have obvious limitations in power supply and replacement, and there is an urgent need for a new design scheme for switch modules that can achieve the independence of the switch module and the power supply structure, so as to facilitate users to replace and upgrade the switch module alone and improve the convenience and flexibility of lamp use.

[0020] The following is a description of a preferred specific embodiment of the present invention in conjunction with the accompanying drawings.

[0021] Refer to Figures 1 to 5 , this embodiment provides a switch device, especially applied to lamps, for electrically connecting with the lamps, so as to control the on and off of the lamps through the switch device. Of course, it can also be applied to other electrical equipment to control the start and stop of the electrical equipment. The switch device includes a base 1 and an induction module 2. The base 1 is configured with an installation cavity 11 with an open upper side. A first circuit board 12 is arranged in the installation cavity 11. A busbar connector 13 electrically connected to the first circuit board 12 is arranged on the outer side of the base 1. A power supply part 121 is configured on the first circuit board 12. The induction module 2 includes a housing 21 detachably inserted into the installation cavity 11. A second circuit board 22 is configured in the housing 21. The second circuit board 22 is located at the end far from the base 1 (i.e., Figure 2 the top end) is connected with a trigger part 23. A contact part 28 corresponding to the power supply part 121 is also configured on the second circuit board 22. The contact part 28 can be controlled to contact the power supply part 121 when the housing 21 is assembled in the installation cavity 11 to supply electrical energy to the trigger part 23.

[0022] Refer to Figure 2 , a plurality of outwardly protruding clamping points 2110 are arranged on the outer side wall of the housing 21. When the housing 21 is assembled in the installation cavity 11, the clamping points 2110 are pressed against the inner side wall of the installation cavity 11 to achieve a tight fit, thereby preventing loosening between the housing 21 and the base 1 and ensuring close and reliable contact between the power supply part 121 and the contact part 28.

[0023] Refer to Figure 4 , a longitudinally extending slot 14 is arranged at the bottom of the installation cavity 11. The first circuit board 12 is inserted into the slot 14 from top to bottom. An opening 15 is formed at the bottom of the base 1 adjacent to the slot 14. The wire 16 connecting the first circuit board 12 extends out of the base 1 through the opening 15 and is connected to the busbar connector 13. The above-mentioned first circuit board 12 is convenient and quick to install.

[0024] Refer to Figure 2 and Figure 3, the housing 21 includes a top cover 211 and a bottom case 212 that are detachably connected. The top cover 211 and the bottom case 212 enclose an assembly cavity 213 for accommodating the second circuit board 22. The bottom case 212 includes a connection end 214 for connecting to the top cover 211 and a power connection end 215 provided on one side of the connection end 214. A through hole 216 is provided on the side of the power connection end 215 corresponding to the contact portion 28. The contact portion 28 extends out of the power connection end 215 through the through hole 216. The power connection end 215 can be operably placed on the side of the first circuit board 12 when the housing 21 is assembled in the installation cavity 11, so that the contact portion 28 contacts the power supply portion 121. The above arrangement of the bottom case 212 and the cooperation with the first circuit board 12 can make the layout more compact and save more space.

[0025] See Figure 2 and Figure 3 , the connection end 214 is provided with a number of reverse buckles 217 extending upward and inserted into the top cover 211. A clamping groove 218 for clamping with the reverse buckles 217 is provided on the side wall of the top cover 211. The connection method between the above top cover 211 and the bottom case 212 is simple and convenient for installation and disassembly. Further, in order to improve the connection strength between the top cover 211 and the bottom case 212 and prevent displacement between the two, the connection end 214 is provided with a limiting convex portion 219 extending upward, and a limiting groove 210 for cooperating with the limiting convex portion 219 is provided at the bottom end of the top cover 211.

[0026] The following provides three specific implementation manners of the induction module 2.

[0027] See Figure 3 , Figure 5 and Figure 6 , as the first setting method, the induction module 2 is a human body induction switch. Specifically: an infrared filter 24 is configured at the end of the housing 21 away from the base 1. The trigger portion 23 includes a light source 231 that emits infrared light toward the infrared filter 24. The second circuit board 22 is connected with a blocking member 232 on the side close to the infrared filter 24. The blocking member 232 is provided with a through hole 233 corresponding to the light source 231. The operator can place the hand outside the infrared filter 24, thereby triggering the trigger portion 23 to turn on or off the electrical equipment.

[0028] See Figure 5 and Figure 6 , as the second setting method, the induction module 2 is an infrared induction switch. Specifically: an infrared mask 25 is configured at the end of the housing 21 away from the base 1. The trigger portion 23 includes an infrared induction probe 234. When the infrared induction probe 234 detects someone nearby, the light is on. When no one is detected, the light is off.

[0029] See Figure 2 , Figure 5and Figure 6 , as a third setting method, the induction mold is a touch switch, specifically: a touch panel 26 is arranged at the end of the housing 21 away from the base 1. The trigger part 23 includes an electrode 235 connected to the second circuit board 22 and a touch spring 236 sleeved on the electrode 235. The touch spring 236 abuts against the bottom of the touch panel 26. The operator can open or close the electrical equipment by touching the touch panel 26. When the touch panel 26 is touched, the touch spring 236 will deform to activate the electrode 235 to form an electrical signal to control the on and off of the electrical equipment.

[0030] See Figure 1 , a radially extending face cover 27 is further provided at the end of the housing 21 away from the base 1. The setting of the face cover 27 facilitates the grasping during the installation and disassembly of the switch device.

[0031] Compared with the prior art, the switch device provided by the present utility model supplies power to the induction module 2 by arranging the base 1 configured with the installation cavity 11. Once the induction module 2 is damaged or the operator wants to replace it with other types of induction modules 2 according to the living needs, the current induction module 2 can be directly disassembled from the base 1, and then a new induction module 2 can be replaced. This setting method realizes the independence of the switch module and the power supply structure, thus facilitating the user to separately replace and upgrade the switch module, and improving the convenience and flexibility of using the electrical equipment.
