It is widely used in motion detection, static sleep mode, power-saving wake-up and other scenarios. The triggering principle of the vibration switch is mainly based on the change of internal conductivity caused by mechanical movement. Its core component is a movable or deformable metal component.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Example 1: like Figures 1 to 9 As shown, Embodiment 1 of this utility model provides a patch vibration switch, comprising: The system comprises a first connecting plate 1, a second connecting plate 2, a third connecting plate 3, and a conductive ball assembly 4, wherein the conductive ball assembly 4 includes two identical conductive balls 41. The first connecting plate 1 has a metallized first connecting hole 11, which serves as one electrode of the patch vibration switch. The second connecting plate 2 is connected to one side of the first connecting plate 1 for insulation. The third connecting plate 3 is connected to the other side of the second connecting plate 2 opposite to the first connecting plate 1, and has a metallized second connecting hole 31, which serves as the other electrode of the patch vibration switch. The second connecting plate 2 has a connecting through hole 21 for connecting the first connecting hole 11 and the second connecting hole 31. The first connecting hole 11, the connecting through hole 21, and the second connecting hole 31 are sequentially connected to form a movable cavity 5. The two conductive balls 41 are movably placed in the movable cavity 5. When the circuit is open, the two conductive balls 41 contact each other and simultaneously contact the first connecting hole 11 and the second connecting hole 31 to enter the open state. When the circuit is closed, the two conductive balls 41 disengage from each other and enter the closed state.

[0021] In Embodiment 1 of this utility model, the first connecting plate 1, the second connecting plate 2, and the third connecting plate 3 are processed in batches using sheet materials. By pre-stacking and pressing the sheet materials with multiple first connecting plates 1, second connecting plates 2, and third connecting plates 3 into a single unit for encapsulation, and then cutting the encapsulated unit to obtain multiple patch vibration switches, the structure of the patch vibration switches becomes more compact and easier to mass-produce using automated production. This achieves the effects of enhancing the overall compactness of the patch vibration switch structure, reducing the overall volume, improving the convenience of its integration and application, and reducing production costs.

[0022] In Embodiment 1 of this utility model, the structure of the double conductive balls 41 is designed such that the two conductive balls 41 are in contact with each other and simultaneously in contact with the first connecting hole 11 and the second connecting hole 31, so that the patch vibration switch enters the conducting state; the two conductive balls 41 are disengaged from each other, so that the patch vibration switch cannot be turned on and enters the disconnected state, thereby improving the sensitivity of the patch vibration switch, enabling the patch vibration switch to accurately respond to the slight vibration or tilt of the electrical appliance, thereby cutting off the circuit in time, and thus enhancing the sensitivity, triggering consistency and compactness of the patch vibration switch.

[0023] In Embodiment 1 of this utility model, the second connecting plate 2 is made of insulating material to separate the first connecting hole 11 and the second connecting hole 31, ensuring that no short circuit will occur after conduction, and enhancing the safety of the patch vibration switch; the first connecting hole 11 and the second connecting hole 31 are connected by metallization, and the metal layer is thickened by chemical copper plating combined with electroplating copper to enhance conductivity, thereby forming two electrodes for conducting external circuits.

[0024] Specifically, the side of the first connecting plate 1 that contacts the second connecting plate 2 is defined as side A, the side of the third connecting plate 3 that contacts the second connecting plate 2 is defined as side B, the diameter of the first connecting hole 11 on side A is equal to the diameter of the second connecting hole 31 on side B, the diameter of the connecting through hole 21 is greater than the diameter of the first connecting hole 11 on side A, and the diameter of the first connecting hole 11 on side A is greater than the diameter of a single conductive ball 41.

[0025] In Embodiment 1 of this utility model, the diameter of the first connecting hole 11 on surface A and the diameter of the second connecting hole 31 on surface B are the same, and the diameter of the connecting through hole 21 is larger than the diameter of the first connecting hole 11 on surface A. Furthermore, the diameter of the first connecting hole 11 on surface A is larger than the diameter of a single conductive ball 41. This ensures that the diameters of all three holes are larger than the diameter of a single conductive ball 41, thereby ensuring the dimensional consistency of the movable cavity 5 and providing a reasonable rolling allowance for the two conductive balls 41. This allows the two conductive balls 41 to roll smoothly within the movable cavity 5 without jamming, thereby improving the triggering sensitivity and conduction reliability of the patch vibration switch.

[0026] Furthermore, the first connecting hole 11 includes a first straight portion 111 and a first arc-shaped portion 112, and the second connecting hole 31 includes a second straight portion 311 and a second arc-shaped portion 312. Along the direction perpendicular to surface A, the length of the first straight portion 111 is defined as L1, the length of the second straight portion 311 is defined as L2, the thickness of the connecting through hole 21 is L3, and the radius of the conductive ball 41 is r1. Then, L1 + L2 + L3 = 2r1.

[0027] In Embodiment 1 of this utility model, the dimension L1+L2+L3=2r1 ensures that when the patch vibration switch is placed horizontally, the two conductive balls 41 can always contact each other through the limiting effect of the movable cavity 5, and the two conductive balls 41 respectively contact the first connecting hole 11 and the second connecting hole 31, so that the patch vibration switch is always in a normally conducting state when it is not subjected to vibration, ensuring the stability of the patch vibration switch during use. At the same time, the dimension L1+L2+L3=2r1 can also effectively ensure that when the patch vibration switch is rotated to other angles, the two conductive balls 41 can also contact each other and simultaneously contact the first connecting hole 11 and the second connecting hole 31, ensuring that the patch vibration switch is always in a normally conducting state at any angle when it is not subjected to vibration.

[0028] In Embodiment 1 of this utility model, the radius of the first arc-shaped part 112 is defined as r2, the radius of the second arc-shaped part 312 is defined as r3, r2=r3, and r2 and r3 are greater than r. The diameter of the first connecting hole 11 on surface A, the diameter of the second connecting hole 31 on surface B, and the diameter of the connecting through hole 21 are all equal to 2r2 or 2r3 to ensure the smooth rolling of the two conductive balls 41.

[0029] Furthermore, surface A is provided with a first connecting line group for conducting external circuits. The first connecting line group includes a first connecting line 121 and a second connecting line 122, which are connected to each other on both sides of the first connecting hole 11.

[0031] Furthermore, the side of the first connecting plate 1 opposite to the A side is defined as the C side. The C side is metallized as a whole and serves as the first pad 13 for connection with external circuits. One end of the first connecting line 121 and the second connecting line 122 are connected to the first connecting hole 11, and the other end is connected to the first pad 13 to conduct the circuit.

[0032] In Embodiment 1 of this utility model, one pole of the surface mount vibration switch is connected to an external circuit through the first pad 13, thereby connecting the first connection hole 11 to the first pad 13 through the first connecting line 121 and the second connecting line 122, so that the first connection hole 11 is connected to the external circuit, improving the convenience of the surface mount vibration switch during installation.

[0033] Furthermore, the outer side of the first connecting plate 1 is also provided with a first conductive channel group for connecting external circuits. The first conductive channel group includes a first conductive channel 141 and a second conductive channel 142. One end of the first conductive channel 141 and the second conductive channel 142 are respectively connected to the first connecting line 121 and the second connecting line 122, and the other end is connected to the first solder pad 13.

[0034] In Embodiment 1 of this utility model, the first conductive channel 141 and the second conductive channel 142 are made conductive by metallization. The metal layer is thickened by chemical copper plating combined with electroplating to enhance conductivity. One end of the first conductive channel 141 and the second conductive channel 142 are respectively connected to the first connecting line 121 and the second connecting line 122, and the other end is connected to the first pad 13. Through the dual-line structure design, as long as any one line of the surface mount vibration switch is conductive, the continuous conduction of the surface mount vibration switch can be ensured, thereby enhancing the reliability and triggering consistency of the surface mount vibration switch during use.

[0035] Furthermore, the B-side is provided with a second connecting wire group for connecting to an external circuit. The first connecting wire group and the second connecting wire group are disposed opposite to each other on both sides of the patch vibration switch. The second connecting wire group includes a third connecting wire 321 and a fourth connecting wire 322, which are connected opposite to each other on both sides of the second connecting hole 31.

[0036] In Embodiment 1 of this utility model, the third connecting line 321 and the fourth connecting line 322 are connected to each other on both sides of the second connecting hole 31 to ensure that the second connecting hole 31 is connected to the external circuit and forms a parallel dual-path, thereby enhancing the stability and reliability of the patch vibration switch during use. At the same time, by having the first connecting line group and the second connecting line group arranged opposite to each other on both sides of the patch vibration switch, short circuits can be effectively avoided after the patch vibration switch is turned on, thereby improving the safety of the patch vibration switch.

[0037] Furthermore, the side of the third connecting plate 3 opposite to the B side is defined as the D side. The D side is metallized as a whole and serves as the second pad 33 for connection with external circuits. One end of the third connecting line 321 and the fourth connecting line 322 is connected to the second connecting hole 31, and the other end is connected to the second pad 33.

[0038] In Embodiment 1 of this utility model, the first pad 13 and the second pad 33 are two relatively independent poles. The other pole of the surface mount vibration switch is connected to the external circuit through the second pad 33, so that the second connection hole 31 is connected to the second pad 33 through the third connection line 321 and the fourth connection line 322, so that the second connection hole 31 is connected to the external circuit and forms a complete circuit after being connected through the two conductive balls 41, thereby improving the convenience of the surface mount vibration switch during installation.

[0039] Furthermore, the outer side of the third connecting plate 3 is also provided with a second conductive group for conducting external circuits.

One end of the third conductive channel 341 and the fourth conductive channel 342 are connected to the third connecting line 321 and the fourth connecting line 322, respectively, and the other end is connected to the second pad 33. Through the dual-line structure design, as long as any one line of the surface mount vibration switch is connected, the continuous conduction of the surface mount vibration switch can be ensured, thereby enhancing the reliability and triggering consistency of the surface mount vibration switch during use. At the same time, both electrodes of the surface mount vibration switch adopt a dual-line structure design, which effectively enhances the stability of the surface mount vibration switch during use.

[0041] Furthermore, the first pad 13 wraps around the C-side and extends partially to the surface between the A-side and the B-side to form a first connection portion 15, and the first connection line 121 and the second connection line 122 are connected to each other on the first connection portion 15; the second pad 33 wraps around the D-side and extends to the surface between the A-side and the B-side to form a second connection portion 35, and the third connection line 321 and the fourth connection line 322 are connected to each other on the second connection portion 35, and the first connection portion 15 and the second connection portion 35 are spaced apart.

[0043] In Embodiment 1 of this utility model, the first connecting part 15 and the second connecting part 35 are spaced apart to avoid short circuits when the patch vibration switch is soldered onto the PCB board 6, thereby improving the safety of the vibration switch during use.

[0044] In some other embodiments, sockets can be provided on the first pad 13, the second pad 33, the first mounting pad 61, and the second mounting pad 62 respectively.

One end of the fifth guide channel 143 and the sixth guide channel 144 are connected to the fifth connecting line 123 and the sixth connecting line 124, respectively, and the other end is connected to the first pad 13. Through the symmetrical structural design of the four-line trace, the surface mount vibration switch can be continuously connected as long as any one line is connected, which enhances the reliability and triggering consistency of the surface mount vibration switch during use. In Embodiment 2 of this utility model, the fifth guide channel 143 and the sixth guide channel 144 are connected by metallization.

One end of the seventh conductive channel 343 and the eighth conductive channel 344 are connected to the seventh connecting line 323 and the eighth connecting line 324, respectively, and the other end is connected to the second pad 33. Through the symmetrical four-line structure design, as long as any one line of the surface mount vibration switch is conductive, the continuous conduction of the surface mount vibration switch can be ensured, thereby enhancing the reliability and triggering consistency of the surface mount vibration switch during use. At the same time, by adopting a four-line structure design for both electrodes of the surface mount vibration switch, the surface mount vibration switch has a mutually symmetrical structure design, so that the surface mount vibration switch does not need to distinguish the mounting surface in automated assembly, effectively enhancing the installation convenience of the surface mount vibration switch in the production process and greatly improving the efficiency of automated assembly production.
