Description
Technical Field
[0001] This utility model relates to the field of tactile switches, specifically a novel tactile switch. Background Technology
[0002] Tactile switches, also known as push-button switches, have become widely used in electronic devices and white goods due to their advantages such as low contact resistance, precise operating force error, and diverse specifications, thanks to technological advancements and human progress.
[0003] The cover plate and base are usually fixed with simple clips, which are prone to wear and tear due to repeated operation, resulting in loosening or even falling off, affecting the overall stability and service life of the switch. Therefore, a new type of tactile switch is proposed to address the above problems. Utility Model Content
[0004] To address the shortcomings of existing technologies, such as the tendency for the snap-fit structure to wear down due to repeated operation, leading to loosening or even detachment and affecting the overall stability and lifespan of the switch, this utility model proposes a novel tactile switch.
[0005] The technical solution adopted by this utility model to solve its technical problem is as follows: a novel tactile switch, including a base, a cover plate and a pressure block. The base has rectangular blocks at its four corners, and each of the four rectangular blocks has a mounting groove on one side. The mounting grooves penetrate the base, and each of the four mounting grooves has a spring inside. One end of each of the four springs is connected to a limit block. The cover plate is located on the top of the base, and a pair of rectangular plates are provided on both sides of the cover plate. A limit groove is provided on one side of each rectangular plate, and one end of the limit block is located inside the limit groove. A locking block is provided on both sides of the base, and a locking strip is provided between the pair of rectangular plates. The locking block is locked on the top of the locking strip.
[0006] Preferably, there are two pressure blocks, which are respectively fitted into the limiting groove, and one end of each pressure block is connected to a connecting strip.
[0007] Preferably, limiting grooves are provided on both sides of the limiting groove, and sliders are provided on both sides of the pressure block, with the sliders fitting in the limiting grooves.
[0008] Preferably, the four limiting blocks are arranged in two pairs, with the two pairs of limiting blocks located on both sides of the base and corresponding to the two limiting grooves.
[0009] Preferably, the top end of the limiting block is designed as a sloped structure.
[0010] Preferably, the top side of the card strip is designed with a beveled structure.
[0011] Preferably, a sealing strip is provided between the base and the cover plate.
[0012] Preferably, a button is fitted at the top center of the base.
[0013] The advantages of this utility model are: 1. This utility model achieves multi-point, flexible, and automatic locking between the cover plate and the base by using an elastic locking structure composed of springs and limiting blocks on both sides of the base in conjunction with the limiting groove on the cover plate. This makes the connection more secure, effectively resists impacts and vibrations from all directions, and prevents the cover plate from loosening, making abnormal noises, or falling off due to long-term use or external impacts. This greatly improves the mechanical durability and reliability of the product.
[0014] 2. This utility model utilizes a combination of spring and limiting block structure, allowing for easy installation. Simply press down on the cover plate; the limiting block, under pressure, retracts and automatically springs into the limiting groove under spring action, locking the cover plate in place. During disassembly, the connecting strip drives the pressure block to push the limiting block out of the limiting groove, easily separating the cover plate from the base. The entire process requires no tools or screws, greatly simplifying the assembly process and facilitating subsequent internal maintenance, cleaning, or parts replacement, thus reducing lifecycle costs.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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 scope of protection of the present utility model.
[0019] The following is in conjunction with the appendix Figures 1-5 This application will be described in further detail. This application discloses a novel tactile switch. (Refer to...) Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 A novel tactile switch includes a base 1, a cover plate 2, and a pressure block 205. Rectangular blocks 101 are located at the four corners of the base 1. Each of the four rectangular blocks 101 has a mounting groove 102 on one side. The rectangular blocks 101 provide strength and support, ensuring the structural integrity of the mounting grooves 102. The mounting grooves 102 penetrate the base 1 and serve as guide and receiving channels for precisely fixing the movement trajectories of springs 103 and limit blocks 104. Springs 103 are located inside the four mounting grooves 102, providing continuous elastic restoring force. One end of each spring 103 is connected to a limit block 104, which acts as a locking tongue, directly engaging with the limit groove 202 on the cover plate 2 to achieve mechanical locking. 2 is located on the top of the base 1. A pair of rectangular plates 201 are provided on both sides of the cover plate 2. The rectangular plates 201 are located on both sides of the cover plate 2 and are mating parts of the locking structure. A limiting groove 202 is opened on one side of the rectangular plate 201. One end of the limiting block 104 is set inside the limiting groove 202. The limiting groove 202 is a locking hole used to accommodate and lock the limiting block 104 extending from the base 1. A locking block 105 is provided on both sides of the base 1. A locking strip 204 is provided between the pair of rectangular plates 201. The locking block 105 is locked on the top of the locking strip 204. The locking block 105 and the locking strip 204 are an auxiliary locking and positioning system. Together with the locking buckles at the four corners, they form a connection system with clear primary and secondary functions and multiple protections, which greatly enhances the overall rigidity and stability of the structure.
[0020] Reference Figure 4 There are two pressure blocks 205, which are respectively fitted into the limiting grooves 202. The function of the pressure blocks 205 is to apply pressure to the limiting block 104 from the inside when disassembly is required, so that it exits the limiting grooves 202. One end of the two pressure blocks 205 is connected to a connecting strip 207, which connects the two pressure blocks 205 together to achieve synchronous movement. Only one part needs to be operated to release the locks on both sides at the same time.
[0021] Reference Figure 4 Limiting grooves 203 are provided on both sides of the limiting groove 202, and sliders 206 are provided on both sides of the pressure block 205. The sliders 206 are fitted in the limiting grooves 203. The sliders 206 and the limiting grooves 203 form a guide structure to ensure that the pressure block 205 can only move smoothly in the vertical direction, prevent it from deflecting, and accurately transmit the force to the limiting block 104.
[0022] Reference Figure 5 The four limit blocks 104 are in two pairs, and the two pairs of limit blocks 104 are located on both sides of the base 1 and correspond to the two limit grooves 202.
[0023] Reference Figure 2 and Figure 5 The top end of the limiting block 104 is designed with a sloping structure to facilitate the compression of the limiting block 104 to make it shrink.
[0024] Reference Figure 4 The top side of the card strip 204 is designed with a sloping structure, and the sloping surface at the top of the card strip 204 is used for guidance.
[0025] Reference Figure 3 A sealing strip 4 is provided between the base 1 and the cover plate 2. The sealing strip 4 forms an elastic sealing barrier between the mating surfaces of the base 1 and the cover plate 2, which can effectively block dust, moisture and other pollutants from entering the switch and prevent internal contact oxidation and short circuit.
[0026] Reference Figure 1 , Figure 2 and Figure 3 The top center of the base 1 is fitted with a button 3, which is the user's operating interface and transmits external pressing pressure to the internal spring mechanism.
[0027] Working principle: By aligning the cover plate 2 with the base 1, the limiting grooves 202 on the rectangular plates 201 on both sides of the cover plate 2 are roughly aligned with the limiting blocks 104 at the four corners of the base 1. At the same time, the locking strips 204 on the cover plate 2 are also aligned with the locking blocks 105 on both sides of the base 1.
[0028] When the cover plate 2 is pressed down, the inclined surface at the top of the limiting block 104 contacts the edge of the limiting groove 202. This inclined surface structure converts the vertical downward pressure into a horizontal component force that causes the limiting block 104 to retract into the mounting groove 102. The limiting block 104 moves inward, compressing the spring 103 behind it. When the cover plate 2 is fully attached to the top of the base 1, the limiting block 104 moves to a position that is perfectly aligned with the limiting groove 202. At this moment, the compressed spring 103 releases its elastic force instantly, pushing the limiting block 104 outward and firmly locking it into the limiting groove 202, while making a crisp "click" sound, indicating that the locking is complete. At the same time, the locking block 105 also slides over the top of the locking strip 204 and locks in place, providing additional longitudinal locking force to prevent the front end of the cover plate 2 from tilting up.
[0029] Throughout the process, the sealing strip 4 located between the base 1 and the cover plate 2 is evenly compressed to form a reliable sealing ring, effectively isolating external dust and moisture.
[0030] When maintenance is required, the operator simply presses the connecting strip 207. The connecting strip 207 drives the pressure blocks 205 at both ends to move smoothly inward along the guide rail formed by the slider 206 and the limiting groove 203. The movement of the pressure blocks 205 directly acts on the inclined surface of the limiting block 104, pushing it out of the limiting groove 202 and forcing the spring 103 to compress again. When all four limiting blocks 104 are pushed back into the mounting groove 102 by the pressure blocks 205, the lock is completely released. At this time, simply lift the cover plate 2 upward to separate it from the base 1, and the locking block 105 will also disengage from the locking strip 204, thus completing the disassembly of the cover plate 2.
[0031] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
