Description

Technical Field

[0001] This utility model relates to the field of switch technology, specifically to a seating sensing module structure based on the micro-switch recognition principle. Background Technology

[0002] A microswitch is a simple, low-failure-rate position sensor typically used to detect whether a component is in place or not. Seat sensing based on recognition principles is a mature and practical technology, particularly suitable for scenarios requiring mechanical contact feedback. In devices such as smart toilets, microswitches are widely used in seat sensing functions, triggering corresponding operations, such as activating heating or flushing functions, by detecting the physical contact when a user sits down.

[0003] A typical micro switch consists of a housing, contacts, and a pressing surface. The housing has a pressing surface. In toilet seat sensing applications, the switch is usually embedded in the seat surface and triggered by pressing down on the seat. When external force is applied to the pressing surface, the pressing surface presses down on the pressing piece, causing the pressing piece to come into contact with the contact, thus closing or opening the contact. When a person sits down and then gets up again, it triggers functions such as flushing the toilet.

[0004] However, due to the tilting pressure exerted on the pressing surface when a person sits down, the microswitch is prone to sliding sideways under pressure, leading to contact misalignment and wear.

[0005] Based on this, this utility model designs a seating sensing module structure based on the micro-switch recognition principle to solve the above problems. Utility Model Content

[0006] To achieve the above objectives, the present invention provides the following technical solution: a plurality of pressing rods are evenly distributed at the bottom of the pressing surface, and a pressing point is fixedly provided at the other end of the pressing rod. The plurality of pressing points are spliced ​​together to form a pressing block located directly above the pressing sheet. A guide ring is fixedly provided on the pressing sheet. When the pressing block comes into contact with the pressing sheet, the guide ring surrounds the pressing block.

[0007] By adopting the above technical solution, when the pressing surface is subjected to an external force from the inclined direction, the pressure is transmitted to the pressing rod. The pressure is evenly distributed by multiple pressing rods. The surrounding design of the guide ring and the pressing block ensures that the downward pressure is transmitted vertically, so that the contact can maintain vertical downward movement when pressed, reducing contact wear caused by lateral displacement and extending the life of the micro switch.

[0008] Preferably, a limiting groove is formed on the inner sidewall of the guide ring, and a raised slide rail matching the limiting groove is provided on the sidewall of the pressing block.

[0009] By adopting the above technical solution, the rigid constraint of the slide rail and the limiting groove restricts the pressing block to only move vertically, and sliding friction replaces free shaking, so that the pressing block can maintain stable vertical downward pressure during the movement.

[0010] Preferably, two support columns are fixedly provided at the bottom of the pressing surface, and positioning blocks are symmetrically provided on both sides of the pressing sheet. Positioning grooves are provided on the positioning blocks, and the lower end face of the support column is clearance-fitted with the bottom surface of the positioning groove.

[0011] By adopting the above technical solution, the support column and the positioning groove form a secondary guide, which can further prevent the horizontal displacement of the pressing block.

[0012] Preferably, the pressing plate is an X-shaped symmetrical cantilever beam structure, with its center point directly opposite the pressing block, and the contact point is located on the central axis of the pressing plate.

[0013] By adopting the above technical solution, the X-shaped structure deforms symmetrically, and even if the pressing block is subjected to eccentric force, the contact point can still be triggered vertically.

[0014] Preferably, the pressing rod is provided with a reinforcing platform on the side near the pressing surface.

[0015] By adopting the above technical solution, the reinforcement platform increases the strength of the root of the pressing rod, prevents plastic deformation caused by repeated pressing, and allows the pressure to be transmitted to the pressing block more concentratedly.

[0016] Preferably, the contact surface between the pressing block and the pressing sheet is provided with a polyurethane buffer layer.

[0017] By adopting the above technical solution, polyurethane material absorbs impact energy, reduces mechanical noise when the contacts close, and can also protect the contacts.

[0018] Preferably, the pressing surface is an upwardly arched arc-shaped surface.

[0019] By adopting the above technical solution, the matching degree between the curved surface and the curve of the buttocks or thighs of the human body is improved, so that the pressure is evenly distributed to multiple pressing rods, avoiding excessive local pressure.

[0020] In summary, this application has the following beneficial technical effects: when the pressing surface is subjected to an external force from the inclined direction, the pressure is transmitted to the pressing rod, the pressure is evenly distributed by multiple pressing rods, and the surrounding design of the guide ring and the pressing block ensures that the downward pressure is transmitted vertically, so that the contact can maintain vertical downward movement when pressed, reducing contact wear caused by lateral offset and extending the life of the micro switch.

[0029] 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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0030] The following is in conjunction with the appendix Figure 1-5 This application will be described in further detail.

[0031] A seating sensing module structure based on the micro-switch recognition principle includes a housing 1, contacts 3, and a pressing plate 10. The housing is made of silicone material and has a pressing surface. A silicone sleeve 14 is provided inside the housing 1, and a pressing surface 2 is provided on the silicone sleeve 14. The pressing plate 10 and contacts 3 are sequentially distributed directly below the pressing surface 2. The housing 1 is embedded into the seat surface. Several pressing rods 7 are evenly distributed at the bottom of the pressing surface 2. The pressing rods 7 are evenly stacked and distributed with the center of the pressing surface 2 as the center. The other end of the pressing rod 7 is fixedly provided with a pressing point. Several pressing points are spliced ​​together to form a pressing block 8 located directly above the pressing plate 10. A guide ring 11 is fixedly provided on the pressing plate 10. When the pressing block 8 contacts the pressing plate 10, the guide ring 11 surrounds the pressing block 8.

[0032] When in use, a person sits on the toilet seat and applies pressure to the switch on the seat. The pressing surface 2 deforms under the force, and the pressure is transmitted to the pressing rod 7 at the bottom of the pressing surface 2. The pressing rod 7 transmits and concentrates the pressure on the pressing block 8, causing the pressing block 8 to move vertically downward and press against the pressing plate 10. The pressing plate 10 presses the contact 3 vertically, causing the contact 3 to close or open, realizing the automatic flushing function of the toilet, reducing the wear of the contact 3 caused by lateral displacement, and extending the life of the micro switch.

[0033] A limiting groove 12 is provided on the inner side wall of the guide ring 11, and a raised slide rail 9 matching the limiting groove 12 is provided on the side wall of the pressing block 8. During the downward movement of the pressing block 8, the raised slide rail 9 slides along the limiting groove 12. The raised slide rail 9 can only move downward along the guide ring 11, which rigidly restricts the pressing block 8 to only move vertically, so that the pressing block 8 can maintain a stable vertical downward pressure during the movement. Two support columns 4 are fixedly provided at the bottom of the pressing surface 2, and support blocks 15 are symmetrically provided on both sides of the pressing plate 10. The support blocks 15 are provided with positioning grooves 5. When the pressing surface 2 is subjected to force and moves downward, the support columns 4 move downward and cooperate with the positioning grooves 5 with a clearance to form a secondary guide, which can further prevent the horizontal displacement of the pressing block 8.

[0034] The pressing plate 10 has an X-shaped symmetrical cantilever beam structure, with its center point directly opposite the pressing block 8. The contact point 3 is located on the central axis of the pressing plate 10. The X-shaped structure allows the spring to deform symmetrically during deformation, so that even if the pressing block 8 is subjected to eccentric force, the contact point 3 can still be triggered vertically downward. The pressing rod 7 and the side near the pressing surface 2 are provided with a reinforcing platform 6. The reinforcing platform 6 increases the strength of the root of the pressing rod 7 and prevents plastic deformation caused by repeated pressing, so that the pressure can be transmitted to the pressing block 8 more concentratedly. The contact surface between the pressing block 8 and the pressing plate 10 is provided with a polyurethane buffer layer 13. The polyurethane material can absorb impact energy, reduce the mechanical noise when the contact point 3 is closed, and reduce the impact force of the pressing plate 10 on the contact point 3. The pressing surface 2 is an upwardly arched arc surface. When a person sits on the surface of the toilet seat, the arc surface can distribute the pressure more evenly, avoid pressure concentration, and prevent damage to the pressing surface 2.

[0035] The implementation principle of this embodiment is as follows: When in use, a person sits on the surface of the toilet seat and applies pressure to the switch on the seat. The pressing surface 2 deforms under the force, and the pressure is transmitted to the pressing rod 7 at the bottom of the pressing surface 2. The pressing rod 7 transmits and collects the pressure onto the pressing block 8. As the pressing block 8 moves downward, the protruding slide rail slides along the limiting groove 12, so that the limiting block can only move downward along the guide ring 11. The rigid constraint restricts the pressing block 8 to only move vertically, so that the pressing block 8 can maintain a stable vertical downward pressure during the movement. After the pressing block 8 moves down, it presses against the pressing plate 10. When the pressing surface 2 moves downward under the force, the support column 4 moves down accordingly and fits with the positioning groove 5 with a clearance to form a secondary guide. The pressing plate 10 presses the contact 3 vertically, causing the contact 3 to close or open, realizing the automatic flushing function of the toilet, reducing the wear of the contact 3 caused by lateral displacement, and extending the life of the micro switch.
