Description

Technical Field

[0001] This utility model relates to the field of switchgear, and in particular to a touch switch with multiple trigger points. Background Technology

[0002] In existing electronic devices, touch switches are common control elements and are widely used in energy-saving automatic lighting places such as corridors, stairwells, restrooms, basements, garages, warehouses, and monitoring systems.

[0003] Traditional push-button switches typically employ a single-plane button design. For example, Chinese patent CN210668179U discloses a push-button switch with a single-plane button panel. If multiple microswitches are used, pressing the button panel can lead to accidental activation. If multiple microswitches are needed to control electrical appliances, multiple independent push-button switches must be installed side-by-side, which takes up a lot of space and makes it difficult to achieve a compact layout.

[0004] In view of this, the present invention proposes a touch switch with multiple trigger points to solve the above problems. Utility Model Content

[0005] To overcome the shortcomings of the above-mentioned technology, this utility model provides a touch switch with multiple trigger points, which is less prone to accidental activation, and has a compact structure and occupies little space.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A touch switch with multiple trigger points includes a housing and a button panel. The button panel includes at least two non-coplanar unit plates. At least two microswitches are provided at the front end of the housing. Each unit plate is opposite to at least one microswitch. A snap-fit ​​structure and a reset structure are provided between the front end of the housing around each microswitch and the back of the button panel. The snap-fit ​​structure is used to movably connect the button panel to the housing, and the reset structure is used to reset after pressing the unit plate.

[0008] Preferably, the button panel includes three unit plates, each unit plate including a first horizontal plate and two first inclined plates. The first horizontal plate extends in the left-right direction and is perpendicular to the front-back direction. The first horizontal plate has first inclined plates on both the top and bottom sides. The first inclined plates are inclined from the first horizontal plate toward the housing. The button panel has a convex front and concave back structure.

[0009] Preferably, the housing includes a front shell, the front end of the front shell is provided with a mounting groove, the mounting groove is provided with a mounting panel, a PCB is mounted between the mounting groove and the mounting panel, the micro switch is disposed on the PCB, and the mounting panel is provided with a switch through hole for the micro switch to pass through.

[0010] Preferably, the mounting panel includes a second horizontal plate and second inclined plates located on the upper and lower sides of the second horizontal plate respectively. The second horizontal plate is parallel to the first horizontal plate, and the second inclined plate is parallel to the opposite first inclined plate. Both the second horizontal plate and the second inclined plate are provided with switch through holes.

[0011] Preferably, the touch switch has four micro switches, and each of the left and right sides of the second horizontal plate has a switch through hole, and each of the second inclined plates has a switch through hole.

[0012] Preferably, the buckle structure includes a buckle disposed on the back of the button panel and a guide hole disposed on the mounting panel, the buckle passing through the guide hole, and the edge of the guide hole having a snap-fit ​​protrusion for engaging with the buckle.

[0013] Preferably, the reset structure includes an elastic element located in a guide hole and a pressing protrusion disposed on the back of the button panel, the pressing protrusion being used to press the elastic element.

[0014] Preferably, the snap-fit ​​structure and the reset structure are located at the junction of the first horizontal plate and the first inclined plate, and a snap-fit ​​structure and a reset structure are located between two adjacent switch through holes.

[0015] Preferably, the mounting panel has a first protruding edge near its edge, and the back of the button panel has a first groove for engaging with the first protruding edge. The first protruding edge and the first groove cooperate to limit the distance of the latch movement when the button panel is pressed.

[0016] Preferably, the touch switch further includes a decorative cover fixedly connected to the front of the button panel, the shape of which is adapted to the shape of the button panel.

[0017] Compared with the prior art, the beneficial effects of this utility model are:

[0018] 1. The button panel of this utility model includes at least two non-coplanar unit plates, each unit plate being opposite to at least one micro switch. When the user presses different unit plates, the corresponding micro switch can be precisely triggered, avoiding accidental activation of other micro switches and improving control accuracy. Compared with the prior art, this utility model eliminates the need for multiple independent single-plane button plates installed side by side, reducing installation space and making the switch layout compact.

[0027] The implementation, functional features and advantages of this utility model will be further explained in conjunction with the embodiments and with reference to the accompanying drawings. Detailed Implementation

[0028] The following embodiments further illustrate the features of this utility model and other related features in detail, so as to facilitate understanding by those skilled in the art:

[0029] Reference Figures 1-6 This utility model provides an embodiment of a touch switch with multiple trigger points.

[0030] A touch switch with multiple trigger points includes a housing 1 and a button panel 2. The button panel 2 includes at least two non-coplanar unit plates 21. The front end of the housing 1 is provided with at least two microswitches 31. Each unit plate 21 is opposite to at least one microswitch 31. A snap-fit ​​structure and a reset structure are provided between the front end of the housing 1 and the back of the button panel 2 around each microswitch 31. The snap-fit ​​structure is used for the button panel 2 to be movably connected to the housing 1, and the reset structure is used to reset after pressing the unit plate 21.

[0031] like Figure 2 As shown, the housing 1 includes a front housing 4, the front end of the front housing 4 is provided with a mounting groove 41, the mounting groove 41 is provided with a mounting panel 5, a PCB 3 is installed between the mounting groove 41 and the mounting panel 5, a micro switch 31 is provided on the PCB 3, the mounting panel 5 is provided with a switch through hole 51, the micro switch 31 can pass through the switch through hole 51, so that the button panel 2 presses the micro switch 31.

[0032] like Figure 1 As shown, the button panel includes three unit plates 21, each including a first horizontal plate 211 and two first inclined plates 212. The first horizontal plate 211 extends in the left-right direction and is perpendicular to the front-back direction. The first horizontal plate 211 has first inclined plates 212 on both its upper and lower sides, and the first inclined plates 212 are inclined from the first horizontal plate 211 toward the housing 1.

[0033] The first inclined plate 212 and the first horizontal plate 211 form a front-convex and rear-concave structure for the button panel 2. The user presses the unit plate 21 backward, which conforms to the pressing habits of most users.

[0034] The mounting panel 5 includes a second horizontal plate 52 and second inclined plates 53 located on the upper and lower sides of the second horizontal plate 52, respectively. The second horizontal plate 52 is parallel to the first horizontal plate 211, and the second inclined plate 53 is parallel to the opposite first inclined plate 212. Both the second horizontal plate 52 and the second inclined plate 53 are provided with switch through holes 51. This structure ensures that the micro switch 31 located on the second horizontal plate 52 or the second inclined plate 53 corresponds precisely to the unit plate 21 of the button panel 2, further ensuring that the micro switch 31 can be accurately triggered when the button panel 2 is pressed, thereby improving the reliability and sensitivity of the switch.

[0035] The touch switch has four microswitches 31, and each second inclined plate 53 has a switch through hole 51. When one of the first inclined plates 212 is pressed, the button panel 2 is subjected to uneven force. The pressed first inclined plate 212 will move backward, and the other parts of the button panel 2 will move forward accordingly. In addition, the first inclined plate 212 and the first horizontal plate 211 are not coplanar, which effectively avoids accidentally touching other microswitches 31 when the micro switch 31 corresponding to the first inclined plate 212 is triggered.

[0036] The second horizontal plate 52 has a switch through hole 51 on each of its left and right sides, that is, there is a micro switch 31 on each of the left and right sides of the second horizontal plate 52. The two micro switches 31 are far apart. When the left side of the first horizontal plate 211 is pressed, the first horizontal plate 211 is subjected to uneven force. The left side of the first horizontal plate 211 moves backward, triggering the micro switch 31 located on the left side of the second horizontal plate 52. The right side of the first horizontal plate 211 moves forward, without triggering the micro switch 31 located on the right side of the second horizontal plate 52.

[0037] When a user presses different unit panels 21, the corresponding micro switch 31 can be precisely triggered, avoiding accidental activation of other micro switches 31 and improving control accuracy. Existing switches require multiple independent single-plane button panels to independently control multiple micro switches, with these panels installed side-by-side. Compared to existing technologies, this invention uses a single button panel 2 to control multiple micro switches 31, reducing installation space and resulting in a more compact switch layout.

[0038] like Figures 2-3 As shown, the latching structure includes a latch 22 disposed on the back of the button panel 2 and a guide hole 54 disposed on the mounting panel 5. The latch 22 passes through the guide hole 54, and the edge of the guide hole 54 is provided with a snap-fit ​​protrusion 55 for engaging with the latch 22. The reset structure includes an elastic element 56 located in the guide hole 54 and a pressing protrusion 23 disposed on the back of the button panel 2. The pressing protrusion 23 is used to press the elastic element 56.

[0039] In this embodiment, the elastic element 56, the snap-fit ​​protrusion 55, and the mounting panel 5 are integrally formed. The mounting panel 5 is made of metal or plastic with a certain degree of elasticity. The buckle 22, the pressing protrusion 23, and the button panel 2 are integrally formed.

[0040] like Figure 5 As shown, when the unit plate 21 is pressed, the corresponding latch 22 of the unit plate 21 moves backward and disengages from the latching protrusion 55. At the same time, the pressing protrusion 23 presses backward against the elastic element 56, causing the elastic element 56 to generate a restoring force, and the unit plate 21 triggers the micro switch 31. When the unit plate 21 is no longer pressed, the restoring force generated by the elastic element 56 causes the unit plate 21 to move forward, and the latch 22 resets and engages with the latching protrusion 55.

[0041] The latching structure and the reset structure are located at the junction of the first horizontal plate 211 and the first inclined plate 212, and one latching structure and one reset structure are located between two adjacent switch through holes 51. This ensures that when one of the microswitches 31 is pressed, a latching structure and a reset structure on each side of the microswitch 31 work together, resulting in uniform force on the microswitch 31 and greater stability when pressed. Moreover, one latching structure and one reset structure are used for the coordinated action of two adjacent microswitches 31, reducing the number of reset structures and latching structures required and further simplifying the switch structure.

[0042] The mounting panel 5 has a first raised edge 57 near its edge, and the back of the button panel 2 has a first groove 24 for engaging with the first raised edge 57. The first raised edge 57 and the first groove 24 work together to limit the distance the latch 22 moves when the button panel 2 is pressed.

[0043] The gap between the first protruding edge 57 and the wall of the mounting groove 41 is the second groove 42. The button panel 2 is provided with a second protruding edge 25 around the first groove 24, and the second protruding edge 25 is located in the second groove 42. When the unit plate 21 is pressed, the second protruding edge 25 moves back and forth in the second groove 42, and the first protruding edge 57 moves back and forth in the first groove 24, which serves as a guide.

[0044] like Figure 6 As shown, the touch switch also includes a decorative cover 6 fixedly connected to the front of the button panel 2, used to conceal the structure of the button panel 2 and make the switch more aesthetically pleasing. The shape of the decorative cover 6 is adapted to the shape of the button panel 2. The touch switch also includes a rear cover 7 connected to the rear end of the front cover 4, and other electronic components of the touch switch are installed inside the rear cover 7.

[0045] The above description is only a preferred embodiment of the present utility model and does not limit the patent scope of the present utility model. Any equivalent structural transformations made based on the contents of the present utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of the present utility model.
