Description
Technical Field
[0001] This utility model is a vibration switch for electronic shoe lights, belonging to the field of patch spring vibration switches. Background Technology
[0002] With the improvement of people's living standards and the advancement of technology, smart wearable devices are becoming increasingly popular. Electronic shoe lights, as a smart wearable product that combines fashion, fun and safety, are favored by teenagers and sports enthusiasts. Their working principle is usually to sense the impact and vibration of the user's footsteps through a built-in vibration switch, thereby triggering the LED beads to light up, achieving a cool visual effect or nighttime lighting warning function.
[0003] Currently, common vibration switches on the market, such as ball switches, connect the circuit through the rolling of a metal ball. These switches have significant directional limitations; the installation angle must be accurate, otherwise false triggering or failure to trigger can easily occur. This makes them unsuitable for products like electronic shoe lights that operate under complex motion conditions. Furthermore, traditional vibration switches often use open or simple encapsulation structures, making their internal metal contacts susceptible to corrosion from moisture and dust in the environment, leading to oxidation, poor contact, low reliability, and a short lifespan.
[0004] Although some improved switches attempt to address the aforementioned issues, the process of achieving omnidirectional triggering often leads to a more complex internal structure (such as the use of multiple springs and multiple contact designs), which not only increases manufacturing costs but also poses a severe challenge to the product's sealing process. At the same time, many switches still use through-hole pins (DIP), which are difficult to adapt to the highly automated surface mount technology (SMT) manufacturing process of modern electronic products, limiting production efficiency and product miniaturization. Utility Model Content
[0005] To address the shortcomings of existing technologies, the purpose of this utility model is to provide a vibration switch for electronic shoe lights, thereby solving the technical problem that existing vibration switches lack omnidirectional triggering, high sealing performance, long service life, and suitability for automated mounting.
[0006] To achieve the above objectives, this utility model provides the following technical solution: a vibration switch for electronic shoe lights, comprising:
[0007] The switch body has an internal mounting chamber and a first pin and a second pin extending from its left and right sides. A fixing seat is fixedly connected inside the mounting chamber.
[0008] The metal pressure cap is electrically connected to the first pin and is fixedly installed at the opening of the switch body, with its inner wall abutting against the left side of the fixing base.
[0009] A spring is composed of a first spring part and a second spring part, an end of the first spring part is clamped and fixed by the fixed seat and electrically connected with the hardware pressure cap through the fixed seat, a free end of the second spring part is arranged in a spaced manner with the second pin, and the second spring part can be deformed in multiple directions when vibrating, so that the free end is triggered and turned on in all directions.
[0010] Further, the free end of the second spring part is provided with a conductive contact protruding towards the second pin.
[0011] Further, the inner wall of the switch body is provided with a continuous annular conductive area, and the conductive contact can form electric conduction in any direction with the annular conductive area.
[0012] Further, when vibrating, the second spring part can be elastically deformed in multiple directions, so that the conductive contact at the end part contacts the second pin or the annular conductive area, thereby forming a conductive path between the first pin and the second pin or between the first pin and the switch body.
[0013] Further, the first spring part and the second spring part are an integral molding structure.
[0014] Further, the spring pitch in the second spring part is smaller than the spring pitch of the first spring part.
[0015] Further, the switch body is made of metal material and is an integral molding structure with the first pin and the second pin.
[0016] Further, the side of the fixed seat in contact with the inside of the switch body is provided with a protruding fixed block, and the two sides of the mounting chamber are provided with clamping grooves matched with the shape of the fixed block, so as to realize accurate positioning of the fixed seat in the mounting chamber.
[0017] Further, the first pin and the second pin are surface mount pins and are fixedly installed on the PCB through a welding process.
[0018] Further, the hardware pressure cap and the switch body are sealed through an ultrasonic pressing process or an interference fit mode.

[0020] The utility model creatively takes the switch body of metal material as the shared conductive electrode, and is electrically connected with the first pin, and the inner wall is also equipped with an annular conductive area, to realize all-around triggering conduction. That is, no matter from which direction the vibration comes, after the elastic deformation of the second spring part, the conductive contact of the end part will finally contact with the annular conductive area on any movement track and form conduction, which completely eliminates the sensing blind area of the traditional vibration switch, realizes the triggering success rate of nearly 100%, and can also make extremely sensitive and consistent response to tiny vibration.

[0025] In order to make the technical means, creative features, purposes and effects of the utility model easy to understand, the utility model is further described below in combination with specific embodiments.
[0026] The present application takes the first pin 12 as the left side, and the second pin 13 as the right side.
[0027] Embodiment 1:
[0028] As shown in Figure 1 , Figure 2 , the utility model provides a vibration switch technical scheme for electronic shoe lamp: it includes:
[0029] Switch body 1, inside being equipped with installation chamber 11, and its outside left and right sides being extended and equipped with first pin 12 and second pin 13, the installation chamber 11 inside fixedly clamped and equipped with fixed seat 14;
[0030] Hardware pressure cap 2, with first pin 12 electrically connected, and fixedly installed at the opening of switch body 1, and its inner wall is in contact with the left side of fixed seat 14;
[0031] A spring 3, which is composed of a first spring part 31 and a second spring part 32, the end of the first spring part 31 is clamped and fixed by the fixed seat 14 and is electrically connected with the hardware pressure cap 2 through the fixed seat 14, the free end of the second spring part 32 is arranged in the interval with the second pin 13, the second spring part 32 can be deformed in multiple directions when vibrating, so that the free end realizes omnidirectional triggering conduction.
[0032] In order to improve the reliability and service life of the trigger contact, the free end of the second spring part 32 is provided with a conductive contact 321 protruding towards the second pin 13;
[0033] Wherein, the conductive contact 321 can be treated with precious materials such as gold plating, without the need to treat the entire spring 3, which can effectively control the cost while ensuring the performance, and the plating layer can also effectively prevent oxidation and ensure the service life.
[0034] In order to ensure the high sensitivity and reliability of the switch, the first spring part 31 and the second spring part 32 are integrally formed, and the spring pitch of the second spring part 32 is smaller than that of the first spring part 31;
[0035] Wherein, the first spring part 31 has a larger pitch, which means that its structure is relatively rigid, has a large mass and inertia, and can be used as a "mass block" to remain stationary when vibrating, providing an inertial basis for the movement of the free end of the second spring part 32; the second spring part 32 has a smaller pitch, making its overall structure softer and more flexible, and easily deforming slightly due to inertia; the integrally formed design can effectively ensure the perfect transmission of force between the two spring parts, and the overall structure is more solid and will not break under frequent vibration.
[0036] In order to simplify the production process, the switch body 1 is made of metal material and is integrally formed with the first pin 12 and the second pin 13.
[0037] In order to improve the stability of the fixed seat, the fixed seat 14 is provided with a protruding fixed block 141 on the side in contact with the inside of the switch body 1, and the installation chamber 11 is provided with a clamping groove matched with the shape of the fixed block 141 on both sides, so as to realize the precise positioning of the fixed seat 14 in the installation chamber 11. By adopting the mechanical interlocking structure of "fixed block 141-clamping groove", the standardization of the assembly during automatic production is ensured, and the triggering direction of the spring 3 is always aligned with the second pin 13, maintaining the high consistency of the performance.
[0038] In order to achieve waterproof, dustproof, and oxidation-proof effects, the hardware cap 2 and the switch body 1 are sealed by ultrasonic pressing process or interference fit, the sealing structure can protect the spring 3 and the contact in a dry and clean environment, and fundamentally solves the oxidation and corrosion problems, and significantly improves the environmental tolerance and service life of the product.
[0039] The welding process of the present application is as follows:
[0040] The welding material is pure tin solder paste or solder wire with a tin content of 100%, so as to ensure the purity and reliability of the welding point;
[0041] The welding temperature is strictly controlled within 260℃±10℃, which can ensure that the solder is fully melted and infiltrated to form a good metallurgical bond, and can also avoid overheating to cause thermal damage to the internal plastic parts (such as the switch body 1) and sensitive spring characteristics of the switch.
[0042] The welding time is controlled within 2-2.5 seconds, which can prevent excessive heating of the pins caused by long-term heat exposure and affect the stability of the internal structure.
[0043] In addition, strong acid or strong alkali fluxes cannot be used during the welding process to avoid residual ionic contaminants causing pin corrosion or short circuit due to a humid environment during subsequent use.
[0044] The working principle of the present application is as follows:
[0045] The working principle of the vibration switch is based on inertial mechanics and elastic deformation, and its working process can be divided into three stages:
[0046] 1. Static state (i.e. normal open):
[0047] When not subjected to external vibration, the spring 3 maintains its inherent shape by its own elasticity, at this time, the protruding conductive contact 321 on the free end of the second spring part 32 maintains a small air gap with the second pin 13, and they do not contact each other.
[0048] Therefore, the current path cannot be formed between the first pin 12 and the second pin 13, and the switch is in a stable open (OFF) state, and the load circuit does not work.
[0049] 2. Trigger state (i.e. vibration on):
[0050] When the switch is subjected to external vibration or impact (such as foot landing) with the electronic shoe lamp, the entire switch shell (the switch body 1 and the hardware pressure cap 2) generates acceleration movement, at this time, the second spring part 32 will be elastically deformed (including bending, swinging, twisting and other composite movements) due to inertia relative to the moving shell because of its small pitch, light mass and excellent elasticity, the deformation drives the free end to move to the direction of the second pin 13, and finally causes the gold-plated conductive contact 321 to have instantaneous and reliable physical contact with the second pin 13, thereby forming a complete low-resistance current path, which is momentarily turned on, thereby outputting a clear conduction pulse signal to the external control circuit to trigger the subsequent circuit (such as lighting the LED lamp).
[0051] 3, recovery process (automatic reset):
[0052] When the vibration energy rapidly decays and disappears, the external force driving the second spring part 32 to deform also disappears. At this time, the elastic potential energy stored on the second spring part 32 due to deformation is released, and the free end thereof restores and escapes from the contact with the second pin 13 by virtue of its excellent elastic restoring force, and all components inside the switch return to the original position when the switch is in a static state. The circuit between the first pin 12 and the second pin 13 is re-opened, and waits for the next vibration trigger.
[0053] As described above, the utility model realizes high sensitivity and omnidirectional trigger detection by converting external mechanical vibration energy into internal circuit conduction signals efficiently and reliably through ingenious mechanical structure design.
[0054] Embodiment 2:
[0055] Different from embodiment 1, the core difference of the embodiment is the construction method of the current conduction path.
[0056] In addition to being fixedly connected with the fixed block 141 through the clamping groove and the fixed block 141, the inner wall of the switch body 1 is also provided with a continuous annular conductive area on the right side of the fixed block 141, the entire annular conductive area is subjected to precise machining and surface treatment (such as nickel plating and gold plating), and the annular conductive area covers the movement track of the free end of the second spring part 32 in all possible deformation directions in the radial direction,
[0057] When subjected to vibration or impact in any direction, the second spring part 32 is deformed in multiple directions by virtue of its excellent elasticity, and the conductive contact 321 at the end thereof is displaced.
[0058] In the embodiment 1, the conductive contact 321 must precisely move to contact a specific, small-area second pin 13 to be conductive, while in the present embodiment, the triggering target of the conductive contact 321 is the entire metal inner wall of the switch, and as long as the displacement is sufficient, no matter which direction (left, right, obliquely upward or obliquely downward) it moves, it will eventually contact the annular conductive area on the inner wall of the switch body 1, thereby forming a conductive path between the first pin 12 and the switch body 1.
[0059] The present embodiment provides an innovative vibration switch triggering idea, which uses the metal shell as a full-range conductive electrode by means of ingenuity, achieves the highest level of triggering reliability with the simplest structure, completely eliminates the triggering direction limitation of the traditional vibration switch, greatly reduces the requirements for processing precision, assembly tolerance and spring swing consistency, and significantly improves the yield and long-term use reliability.
