Description

Technical Field

[0001] The utility model relates to the field of switches, in particular to a waterproof vibration switch. Background Art

[0002] A vibration switch is a highly sensitive electronic switch that controls the on / off state of a circuit by sensing vibration, shaking, or tilt. It is widely used in electronic toys, small appliances, sports equipment, and anti-theft devices.

[0003] However, in applications where power is frequently briefly connected and disconnected, the vibration switch's on / off element can become distorted and stuck in the connected position due to the frequent vibrations, causing a short circuit. Furthermore, due to the uncertainty of the vibration direction, the on / off element can easily swing in all directions, resulting in relatively poor sensitivity and affecting the switch's response accuracy. Utility Model Content

[0004] (1) Problems to be solved

[0005] The technical problem to be solved by the utility model is to provide a waterproof vibration switch in view of the current status of the existing technology.

[0006] (2) Technical solution

[0007] The utility model is implemented through the following technical solution: The utility model provides a waterproof vibration switch, comprising a mounting base and a conductive spring. The mounting base is fixedly connected to an outer housing. The mounting base includes a first conductive chassis and a second conductive chassis, with an insulating bottom shell connected between the first and second conductive chassis. The first conductive chassis is mounted with a raised platform, and the first end of the conductive spring is fixed to the raised platform. The second end of the conductive spring is suspended above the second conductive chassis.

[0008] By adopting the above technical solution, a waterproof vibration switch can be made to reliably respond to vibrations using a small number of components. This waterproof vibration switch has a simple structure and an ingenious design. A single waterproof vibration switch is compact, measuring only 3.5mm long and 2.8mm wide. When the switch is placed in a springy toy ball, the external vibrations of the ball act on the vibration switch, forcing the conductive spring to displace, causing its second end to contact the conductive chassis 2, thereby forming a conductive path. The springy toy ball then emits a colorful flash. The conductive spring then returns to its original position, disengaging the conductive chassis 2 and disconnecting the circuit, extinguishing the flash.

[0009] Furthermore, the two abutting bosses of the outer shell abut against both sides of the first end of the conductive spring. A sealing cover is connected and mounted on the upper portion of the outer shell. The conductive spring is located inside the outer shell and can vibrate locally within the closed cavity formed by the outer shell, the mounting seat, and the sealing cover.

[0010] Furthermore, an annular groove is formed on the contact surface between the outer shell and the sealing cover, and the annular groove is used for adding sealing and waterproof glue.

[0011] Furthermore, the material of the conductive chassis 1 and the conductive chassis 2 is electroplated copper foil.

[0012] Furthermore, the outer shell and the insulating bottom shell are made of plastic.

[0013] Furthermore, the raised platform is a hardware raised platform.

[0014] Furthermore, the first end portion of the conductive spring is welded and / or bonded to the raised platform.

[0015] (3) Beneficial effects

[0016] This utility model secures one end of a conductive spring to a protruding platform, and uses a sealing cover and two abutting protrusions to lock the conductive spring while limiting its vibration direction, allowing the waterproof vibration switch to respond quickly and accurately to vibrations. This waterproof vibration switch has a reasonable structure, high sensitivity, high accuracy, and can be recycled multiple times. It also offers excellent waterproof performance, a long lifespan, a compact size, low cost, and is safe and reliable. BRIEF DESCRIPTION OF THE DRAWINGS

[0023] The following will be combined with the accompanying drawings to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative efforts are within the scope of protection of the present invention.

[0025] See also Figure 1-Figure 3 The utility model provides a technical solution: a waterproof vibration switch, comprising a mounting base 1 and a conductive spring 2. The mounting base 1 is fixedly connected to the outer shell 3. The mounting base 1 includes a conductive chassis 101 and a conductive chassis 2 102, and an insulating bottom shell 103 is connected between the conductive chassis 101 and the conductive chassis 2 102. The conductive chassis 1 101 is installed with a raised platform 104, and the first end 201 of the conductive spring 2 is fixed on the raised platform 104. The second end 202 of the conductive spring 2 is suspended above the conductive chassis 2 102. The waterproof vibration switch can reliably respond to vibrations by using a small number of parts. The waterproof vibration switch has a simple structure and a clever design. The size of a single waterproof vibration switch is small, with a length of only 3.5mm and a width of only 2.8mm. The vibration switch is placed in an elastic toy ball. When the toy ball is thrown, its external vibration acts on the vibration switch, causing the conductive spring 2 to displace under the force, and its second end 202 to contact the conductive chassis 2 102, thereby forming a conductive path. The elastic toy ball then emits a colorful flash. The conductive spring 2 then returns to its original position and leaves the conductive chassis 2 102, disconnecting the circuit and extinguishing the flash.

[0026] Additionally, the second conductive chassis 102 may be expanded in volume and disposed around the left, right, and bottom directions of the second end portion 202 to further enhance the sensitivity of the waterproof vibration switch.

[0027] Preferably, the two abutting bosses 301 of the outer shell 3 abut against both sides of the first end 201 of the conductive spring 2. A sealing cover 4 is connected and installed on the upper part of the outer shell 3. The conductive spring 2 is inside the outer shell 3 and can vibrate locally in the closed cavity 5 formed by the outer shell 3, the mounting seat 1, and the sealing cover 4. The abutting bosses 301 on both sides can lock the first end 201 of the conductive spring 2, so that the conductive spring 2 remains in the middle direction and reduces the vibration amplitude of the second end 202. The sealing cover 4 fits and presses the upper part of the conductive spring 2, so that the conductive spring 2 remains horizontal and consistent, while limiting the vibration range of the second end 202 of the conductive spring 2, thereby improving the accuracy of the response. In addition, when the conductive spring 2 rebounds, the rebound trajectory of the second end 202 is blocked by the sealing cover 4, so that the conductive spring 2 can stop vibrating quickly.

[0028] Preferably, the outer housing 3 has an annular groove 302 on its contact surface with the sealing cover 4. This groove is used to deposit waterproof glue. Without the sealing cover 4, the conductive spring 2 is slightly higher than the outer housing 3. The presence of the annular groove 302 and the addition of waterproof glue ensure a tight fit between the sealing cover 4 and the outer housing 3. Furthermore, the waterproof glue prevents moisture from penetrating the waterproof vibration switch, enhancing its safety and stability.

[0029] Preferably, the conductive chassis 1 101 and the conductive chassis 2 102 are made of electroplated copper foil, which has low cost and good conductivity, thus helping to reduce costs.

[0030] Preferably, the outer shell 3 and the insulating bottom shell 103 are made of plastic. Plastic has low cost and good insulation properties, which helps to reduce costs.

[0031] Preferably, the raised platform 104 is a hardware raised platform.

[0032] Preferably, the first end portion 201 of the conductive spring 2 is welded and / or bonded to the raised platform 104. Since the conductive spring 2 is straight, the suspended height of the second end portion 202 of the conductive spring 2 is consistent with the height of the raised platform 104.

[0033] The above description of the disclosed embodiments is intended to enable one skilled in the art to implement or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not limited to the embodiments shown herein, but is intended to conform to the widest scope consistent with the principles and novel features disclosed herein.
