Description

Technical Field

[0001] This utility model relates to the field of electrical appliances, and in particular to a lever-type wall switch. Background Technology

[0002] Toggle switches, with their retro and minimalist appearance and strong design appeal, cater to the market demand for products that combine practicality and aesthetics, and are widely used in various electronic devices and home appliances. The toggle lever is the key component that triggers the switch's on / off state, and plastic is one of the commonly used materials for it. However, plastic toggle levers have insufficient bending strength, and prolonged use can easily lead to bending deformation or even breakage, seriously affecting the switch's lifespan and operational reliability. Utility Model Content

[0003] To address the technical problem of insufficient bending strength of the aforementioned lever, this utility model provides a lever-type wall switch with a composite structure for good bending resistance.

[0004] The specific technical solution of this utility model is as follows: a toggle wall switch, including a toggle, a base, and a cover on the base. An inner button for controlling the on / off state of the control circuit is movably connected inside the base. The cover has a through-hole. The toggle part passes through the through-hole and connects to the inner button, driving the inner button to move. The toggle includes a toggle body that partially passes through the through-hole. A reinforcing core is embedded in the toggle body. The reinforcing core extends along the length direction of the toggle body and passes through the midpoint of its length direction. The material strength of the reinforcing core is higher than that of the toggle body.

[0005] In the aforementioned lever-type wall switch, a reinforcing core is embedded in the lever body, extending along the length direction and passing through the midpoint. The reinforcing core, with its higher material strength than the lever body, forms a composite support structure. The reinforcing core bears the main bending load generated during the toggle operation, effectively reducing the risk of lever deformation or breakage and increasing the overall bending strength of the lever.

[0006] Optionally, the lever body is provided with a mounting groove that matches the reinforcing core, and the reinforcing core extends into the mounting groove to connect the reinforcing core and the lever body.

[0007] In the above technical solution, the lever body and the reinforcing core are made of different materials. Separate assembly can simplify the mold complexity, reduce the molding difficulty, and thus reduce the production and processing costs.

[0008] Optionally, the end of the lever body facing the inner button is provided with a locking part, the groove of the mounting slot is opened in the locking part, and the end of the inner button near the lever body is provided with a corresponding slot. When the locking part and the slot are locked together, the bottom of the slot covers the groove of the mounting slot.

[0009] In the above technical solution, when the snap-fit ​​part snaps into the snap-fit ​​slot, the bottom of the snap-fit ​​slot covers the opening of the mounting slot, forming a physical block in the axial direction of the reinforcing core, thus preventing the reinforcing core from axially detaching from the lever body from the opening of the mounting slot.

[0010] Optionally, the snap-fit ​​part is a straight prism structure, and the adjacent planes are transitioned with rounded corners.

[0011] In the above technical solution, multiple planes of the straight prism are closely fitted with the inner wall plane of the slot, forming a surface contact constraint that restricts the circumferential rotation of the snap-fit ​​part relative to the slot; at the same time, the rounded corners between the planes can reduce edge friction during assembly and facilitate the quick insertion of the snap-fit ​​part into the slot.

[0012] Optionally, the end of the snap-fit ​​part facing the slot is provided with a guide platform. The size of the guide platform decreases along the insertion direction. When the snap-fit ​​part snaps into the slot, the bottom of the slot abuts against the opening of the mounting slot.

[0013] In the above technical solution, the guide table can play a "self-alignment" role when the snap-fit ​​part is snapped into the slot. Its side can guide the snap-fit ​​part to slide into the slot quickly and accurately, effectively reducing assembly difficulty and operation error. When the snap-fit ​​part is fully inserted into the slot, the bottom of the slot just abuts against the opening of the mounting slot, directly preventing the reinforcing core from protruding from the lever body, stabilizing the position of the reinforcing core in the lever, avoiding loosening or displacement due to external force, and ensuring the stability and reliability of the overall structure during use.

[0014] Optionally, the lever further includes a toggle part, which is located on the side of the lever body outside the panel. The toggle part has a flat, round structure and its diameter is wider than the maximum width of the lever body.

[0015] In the above technical solution, the toggle part increases the contact surface between the lever and the finger during operation, making it easier for the user to apply force and optimizing the user experience. At the same time, the flat and round design enhances the aesthetics of the lever.

[0016] Optionally, the connection between the actuating part and the lever body adopts an arc-shaped transition.

[0017] In the above technical solution, the arc transition makes the geometry of the connection smooth and gradual. When the lever is subjected to external forces such as pressing during operation, the stress can be evenly distributed along the arc surface, avoiding local stress concentration and further improving the lever's bending resistance.

[0018] Optionally, the center of the actuating part is recessed, or the surface of the actuating part is provided with friction texture.

[0019] In the above technical solution, the central recessed design changes the surface morphology so that the finger naturally sinks into the recessed area when pressed, forming a physical limit and preventing the finger from slipping; friction textures, such as stripes, particles, and grids, are set on the surface of the actuating part to increase the roughness of the contact surface, prevent the finger from slipping, and optimize the user experience.

[0020] Optionally, the lever may further include a support member, which is located on the side of the lever body that extends into the panel, and the size of the support member is larger than the opening size.

[0021] In the above technical solution, the support component cannot pass through the opening and abuts against the inside of the panel to form a mechanical limiting structure, effectively preventing the lever from detaching from the panel, thereby ensuring that the lever is fixed in the product and improving the stability and reliability of the overall structure.

[0022] Optionally, the reinforcing core is made of metal, and the lever body is made of plastic.

[0023] In the above technical solution, although metal has the characteristics of high strength and high rigidity, using metal materials as the whole not only increases the cost of raw materials, but also increases the manufacturing cost due to complex molding process. Plastic materials have the advantages of low cost, simple molding process and easy mass production. This design applies metal materials to key stress parts and uses plastic materials for other structures, which not only meets the structural strength requirements, but also reduces costs by taking advantage of the lightweight, low cost and easy molding characteristics of plastic materials.

[0024] Compared with the prior art, the present invention has at least the following advantages:

[0025] (1) The lever has good bending resistance and low cost: The lever body is embedded with a metal reinforcing core that extends along the length direction and passes through the midpoint. It forms a composite support structure with the plastic body. During the lever movement, the reinforcing core can bear the main bending load, effectively disperse stress, reduce the risk of lever deformation or breakage, and greatly improve the overall bending strength. This design applies metal materials to key stress parts and uses plastic materials for other structures. This not only meets the structural strength requirements, but also reduces costs by utilizing the lightweight, low cost and easy molding characteristics of plastic materials.

[0026] (2) Stable and reliable structure: The lever is equipped with a support, which abuts against the inside of the panel to form a mechanical limiting structure, effectively preventing the lever from detaching from the panel, thereby ensuring that the lever is fixed in the product.

Detailed Implementation

[0034] The present invention will be further described below with reference to embodiments. Unless otherwise specified, all devices, connection structures, and methods involved in this invention are known in the art.

[0035] Example 1

[0036] Reference Figures 1 to 6 As shown, this utility model provides a toggle-type wall switch, including a toggle 1, a base, and a cover on the base. The base includes a bracket 4, a pressure plate 6, and a base 7 that are detachably connected in sequence. The connection method can be snap-fit ​​or threaded connection. The base 7 is provided with a contact assembly, which includes a moving contact and a stationary contact. The stationary contact has two contact ends, and the moving contact is movably disposed between the two ends of the stationary contact and can contact both ends respectively. An inner button 5 is rotatably connected inside the pressure plate 6. The inner button 5 passes through the pressure plate 6 and contacts the moving contact, driving the moving contact to move and control the circuit opening and closing. The cover consists of an outer panel 2 facing outward and an inner panel 3 located inside the outer panel 2. The cover is provided with a through-hole 9 that passes through the outer panel 2 and the inner panel 3. The toggle 1 passes through the through-hole 9 and connects to the inner button 5, driving the inner button 5 to move. The inner button 5 is provided with a retaining shaft 52, and the pressure plate 6 is provided with a shaft buckle 61. The retaining shaft 52 and the shaft buckle 61 engage to realize the rotatable connection between the inner button 5 and the pressure plate 6. When the user moves lever 1, lever 1 causes inner button 5 to rotate around the retaining shaft 52. Inner button 5 drives moving contact piece to achieve power switch operation.

[0037] The lever 1 includes a lever body 14, part of which passes through the through-hole 9 and is connected to the inner button 5. A reinforcing core 8 is embedded in the lever body 14. The reinforcing core 8 extends along the length direction of the lever body 14 and passes through the midpoint of its length direction. The material strength of the reinforcing core 8 is higher than that of the lever body 14.

[0038] With the above configuration, the lever body 14 is embedded with a reinforcing core 8 that extends along the length direction and passes through the midpoint. The reinforcing core 8 is made of a material with a higher strength than the lever body 14 to form a composite support structure. The reinforcing core 8 bears the main bending load generated during the lever movement, effectively reducing the risk of the lever 1 deforming or breaking and increasing the overall bending strength of the lever 1.

[0039] In this preferred embodiment, the reinforcing core 8 can be made of metal materials such as steel or copper, while the lever 1 can be made of plastic materials such as PC or ABS. Although metals possess high strength and high rigidity, using metal materials throughout not only increases raw material costs but also raises manufacturing costs due to complex molding processes. Plastic materials, on the other hand, have advantages such as low cost, simple molding processes, and ease of mass production. This design applies metal materials to key stress-bearing parts while using plastic materials for other structures, thus meeting structural strength requirements while reducing costs by utilizing the lightweight, low-cost, and easy-to-mold characteristics of plastic materials.

[0040] Furthermore, the outer surface of lever 1 is gold-plated to simulate the color and luster of pure metal, giving lever 1 a metallic appearance. Compared to lever 1 made entirely of metal, this solution effectively reduces material and processing costs while retaining the visual effect of metal, resulting in high cost-effectiveness.

[0041] Example 2

[0042] Based on Embodiment 1, this utility model provides a toggle-type wall switch, such as... Figure 3 As shown, the lever body 14 and the reinforcing core 8 are separate components. The lever body 14 has a mounting groove 15 that fits the reinforcing core 8. The reinforcing core 8 extends into the mounting groove 15 to connect with the lever body 14. The lever body 14 and the reinforcing core 8 are made of different materials. Separate assembly simplifies mold complexity, reduces molding difficulty, and thus reduces production costs. The reinforcing core 8 is preferably in the form of a steel pin, which facilitates insertion into the mounting groove 15.

[0043] In another embodiment, the lever body 14 and the reinforcing core 8 are integrally molded by in-mold injection molding. By pre-placing the reinforcing core 8 in the injection mold and then injecting molten plastic material into the mold cavity, the plastic and the reinforcing core 8 are tightly bonded to form an inseparable integral structure, effectively preventing the two from becoming relatively loose or falling off during use.

[0044] In this embodiment, as Figure 4As shown, the end of the lever body 14 facing the inner button 5 is provided with a locking part 13. The groove of the mounting groove 15 is opened in the locking part 13. The end of the inner button 5 near the lever body 14 is provided with a corresponding slot 51. When the locking part 13 and the slot 51 are engaged, the bottom of the slot 51 covers the groove of the mounting groove 15. An interference fit rib structure can be provided on the inner wall of the slot 51 to form a radial clamping force on the inserted lever 1 through elastic deformation, ensuring a stable connection. Alternatively, the connection strength between the locking part 13 and the slot 51 can be improved by using an adhesive.

[0045] During the use of the switch, the bottom of the slot 51 shields the opening of the mounting slot 15, forming a physical blocking structure in the axial direction of the reinforcing core 8, effectively preventing the reinforcing core 8 from axially separating from the opening of the mounting slot 15, thereby ensuring the connection stability between the lever body 14 and the reinforcing core 8.

[0046] In this embodiment, as Figure 3 As shown, the snap-fit ​​part 13 has a straight prism structure, and the adjacent planes are rounded to transition. A guide platform 16 is provided at one end of the snap-fit ​​part 13 facing the slot 51. The size of the guide platform 16 decreases along the insertion direction. When the snap-fit ​​part 13 snaps into the slot 51, the bottom of the slot 51 abuts against the opening of the mounting groove 15. Multiple planes of the straight prism are in close contact with the inner wall plane of the slot 51, forming a surface contact constraint that restricts the snap-fit ​​part 13 from rotating circumferentially relative to the slot 51. Simultaneously, the rounded transitions between the planes reduce edge friction during assembly, facilitating the quick insertion of the snap-fit ​​part 13 into the slot 51. The guide table 16 can play a "self-alignment" role when the snap-fit ​​part 13 is snapped into the slot 51. Its side can guide the snap-fit ​​part 13 to slide into the slot 51 quickly and accurately, effectively reducing assembly difficulty and operation error. When the snap-fit ​​part 13 is fully inserted into the slot 51, the bottom of the slot 51 just abuts against the opening of the mounting slot 15, directly preventing the reinforcing core 8 from extending out of the lever body 14, stabilizing the position of the reinforcing core 8 in the lever 1, avoiding loosening or displacement due to external force, and ensuring the stability and reliability of the overall structure during use.

[0047] In another embodiment, the snap-fit ​​part 13 has a cylindrical structure, and a guide platform 16 is provided at one end of the snap-fit ​​part 13 facing the slot 51. The diameter of the guide platform 16 decreases along the insertion direction. When the snap-fit ​​part 13 snaps into the slot 51, the bottom of the slot 51 abuts against the opening of the mounting groove 15. The snap-fit ​​part 13 has a cylindrical structure, and the guide platform 16 is frustoconical, which facilitates snap-fit ​​with the slot 51.

[0048] In this embodiment, as Figure 3As shown, the lever 1 also includes a toggle part 11, which is located at the end of the lever body 14 on the side outside the panel. The toggle part 11 has a flattened oval structure, and its diameter is wider than the maximum width of the lever body 14, forming an outwardly flared operating end. This increases the contact area between the lever 1 and the finger during operation, making it easier for the user to apply force and optimizing the user experience. At the same time, the flattened oval design enhances the aesthetics of the lever 1. Furthermore, the connection between the toggle part 11 and the lever body 14 uses an arc-shaped transition. When the lever 1 is subjected to external forces such as pressing during operation, the stress can be evenly distributed along the arc-shaped surface, avoiding localized stress concentration and further improving the bending resistance of the lever 1.

[0049] In this preferred embodiment, the center of the actuating part 11 is recessed, forming a bowl-shaped structure, providing a naturally fitting point for the finger and preventing slippage during operation. Similarly, friction textures can also be provided on the surface of the actuating part 11. These textures can be straight lines, mesh patterns, or arrays of raised dots, etc., to increase surface roughness, significantly improving the friction between the finger and the actuating part 11, preventing slippage during operation, and optimizing the user experience.

[0050] In this embodiment, as Figure 3 As shown, the lever 1 also includes a support member 12, which is located on the side of the lever body 14 that extends into the panel. The size of the support member 12 is larger than the size of the opening 9. The support member 12 can be positioned directly against the inner side of the inner panel 3, or there can be a certain gap between the support member 12 and the inner side of the inner panel 3. During the process of the lever 1 disengaging from the switch, the support member 12 abuts against the inner side of the inner panel 3 to form a mechanical limiting structure, effectively preventing the lever 1 from disengaging from the panel, thereby ensuring that the lever 1 is fixed in the product and improving the stability and reliability of the overall structure. The support member 12 can be plate-shaped or cross-shaped, etc., that can abut against the opening 9. When the locking part 13 and the locking groove 51 are bonded with adhesive, a plate-shaped support member 12 is preferred to cover excess adhesive.

[0051] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model in any way. Any simple modifications, alterations, or equivalent structural transformations made to the above embodiments based on the technical essence of the present utility model shall still fall within the protection scope of the present utility model.
