Description

Technical Field

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

[0002] In traditional wall switch designs, the range of motion of the swing arm is usually defined by a set of carefully designed limit blocks. These limit blocks play a key guiding role, ensuring that the swing arm can move along the predetermined trajectory when operated by the user, thereby realizing the on and off functions of the switch. However, although this design scheme performs well in terms of function, it exposes some problems that cannot be ignored during the production and assembly process.

[0003] First of all, the production process of the limit block is relatively complicated, requiring precise processing and strict quality control. This not only increases the production cost, but also poses a certain challenge to the improvement of production efficiency during large-scale production. In addition, the limit block also requires a high degree of fine operation during the assembly process to ensure that it is correctly installed on the switch body and perfectly matches the swing rod. This not only increases the difficulty of assembly, but may also lead to inconsistent assembly quality, which in turn affects the overall performance and reliability of the product.

[0004] What is more noteworthy is that the traditional limit block design limits the thickness of wall switch products to a certain extent. This has become particularly prominent as the pursuit of thinness and lightness in modern home design continues to upgrade. The limit block needs to occupy a certain space to ensure the normal function of its function, which to a large extent restricts the development of wall switches in the direction of thinner. In the context of fierce market competition, this limitation may affect the market competitiveness of the product.

[0005] In view of the above problems, we believe that it is necessary to improve the traditional wall switch design. By developing new limit mechanisms or adopting more advanced materials and manufacturing technologies, we can reduce production and assembly costs while improving product performance and reliability. In addition, exploring more compact design solutions to meet the needs of modern homes for ultra-thin switches is also an important direction for future development. Such improvements can not only enhance the market appeal of products, but also promote technological progress and industrial upgrading in the wall switch industry. Utility Model Content

[0006] In view of this, the utility model provides a wall switch, creatively designs a new limiting structure of the swing rod, specifically uses a guide rail as the limiting structure of the swing rod, and realizes precise control of the movement range of the swing rod.

[0007] The purpose of the utility model is achieved through the following technical solutions:

[0008] A wall switch comprises a back seat, hardware installed on the back seat, a swing arm that triggers the hardware, a pressure plate that limits the movement trajectory of the swing arm, and a button connected to the swing arm, wherein the pressure plate is provided with an inclined guide rail, the swing arm is provided with a guide rod, and the guide rod extends into the guide rail and can move along the direction limited by the guide rail.

[0009] The rocker arm, as the core actuator, switches the on / off state of the product through precise triggering with the hardware. The rocker arm can slide freely in the guide rail on the pressure plate, and the inclined setting of the guide rail further optimizes the movement trajectory of the rocker arm. This design not only improves the movement efficiency of the rocker arm, but also reduces the friction resistance during operation and prolongs the service life of the switch. The guide rail as a limiting structure for the rocker arm is a major innovation of the utility model. Through the clever design of the coordination with the guide rail, the precise control of the movement range of the rocker arm is achieved. The movement angle of the rocker arm is set to 2.4°, which not only ensures the sensitivity of the operation, but also avoids damage that may be caused by excessive swinging. This design not only improves the user's operating experience, but also ensures the stability and reliability of the switch during long-term use.

[0010] The design of the guide rail allows the swing arm to move accurately on a preset path, ensuring consistency in each operation and improving the reliability of the switch. Since the swing arm slides within the guide rail, wear is reduced and the service life of the switch is extended. The tilt angle of the guide rail is designed with ergonomics in mind, allowing users to easily activate the swing arm when pressing the button without applying excessive force. The compact design of the guide rail allows the switch to adapt to different installation environments and work properly even in limited space, which is conducive to making the switch thinner and improving the aesthetics of the product. With the guidance of the guide rail, the movement of the swing arm is more stable, reducing misoperation caused by external forces or vibrations, and improving the stability of the product.

[0011] Preferably, the guide rail includes a first inclined groove and a second inclined groove dug on the first side of the pressure plate, and the first inclined groove and the second inclined groove are arranged in an inverted figure eight shape. The guide rail also includes a third inclined groove and a fourth inclined groove dug on the second side of the pressure plate, and the third inclined groove and the fourth inclined groove are arranged in an inverted figure eight shape, and the second side is the opposite side of the first side.

[0012] The guide rail adopts a unique design, including four inclined grooves, namely the first inclined groove, the second inclined groove, the third inclined groove and the fourth inclined groove, which are arranged in an inverted figure eight shape. This design not only improves the stability of the overall structure, but also optimizes the guide effect. Specifically, the inverted figure eight arrangement of the first and second inclined grooves and the third and fourth inclined grooves enables the guide rod to disperse the pressure more effectively during the sliding process, reducing the wear or damage caused by the concentrated pressure. At the same time, this design also increases the contact area between the guide rod and the pressure plate, thereby improving the guide efficiency and reducing the friction resistance.

[0013] Preferably, the number of the guide rods is 4, corresponding to the first inclined slot, the second inclined slot, the third inclined slot and the fourth inclined slot respectively.

[0014] There are 4 guide rods, which correspond to the 4 inclined grooves on both sides of the pressure plate. This configuration ensures that the guide rail can provide uniform support force in all directions, avoiding unstable equipment operation due to unbalanced support.

[0015] Preferably, the guide rod is cylindrical in shape.

[0016] The cylindrical appearance design of the guide rod has significant advantages. The cylindrical guide rod is simpler in structure and easier to manufacture, while having good mechanical properties. The cylindrical shape helps to reduce stress concentration in the material, thereby improving the durability and fatigue resistance of the guide rod. In addition, the cylindrical guide rod can provide a more stable guiding effect during the sliding process, reducing the swing or deflection caused by irregular shape, ensuring the smoothness and reliability of the equipment operation.

[0017] Preferably, the pressing plate is installed on the rear seat, the pressing plate is connected to a bracket, a frame is connected to the bracket, and the frame is located at the periphery of the key.

[0018] The design of the pressure plate is also very clever. The pressure plate is installed on the rear seat and connected to it through a bracket, which not only ensures the stability of the pressure plate, but also facilitates adjustment and maintenance. The frame on the bracket is located on the periphery of the button, forming a clear boundary for users to locate and operate. This design not only improves the user experience, but also makes the appearance of the switch product more beautiful.

[0019] Preferably, a pulley for connecting the rocker arm and the button is further provided between the rocker arm and the button, the pulley is rotationally connected to the button, and the pulley and the rocker arm are in point contact or line contact.

[0020] The pulley design between the swing rod and the button is a highlight of the utility model. The pulley is rotatably connected to the button, so that the movement of the swing rod can be smoothly transmitted to the button, achieving precise control. The contact mode between the pulley and the swing rod can be point contact or line contact. This flexibility allows designers to choose the most appropriate contact mode according to specific needs to optimize movement performance and reduce wear. Point contact can provide less friction resistance, while line contact can provide a larger contact area and increase stability.

[0021] Preferably, a slot is provided on the back of the button, a rotating shaft is provided axially of the pulley, and the rotating shaft is rotatably engaged in the slot.

[0022] The slot on the back of the key and the shaft design on the pulley axis greatly improve the adjustability and stability of the device. As a key structure for fixing the pulley position, the slot ensures that the pulley will not shift during operation, thereby ensuring the accuracy and repeatability of the key action. The setting of the shaft allows the pulley to rotate freely in the slot. This design not only facilitates the installation and removal of the pulley, but also ensures the smooth movement of the pulley and reduces the wear caused by friction.

[0023] Preferably, there are one or more pulleys, and the pulleys are evenly distributed on the back of the key.

[0024] The number of pulleys can be one or more. When multiple pulleys are evenly distributed on the back of the key, the key operation sensitivity and response speed can be further improved. This design enables the pulley to distribute pressure more evenly when force is applied, reducing excessive reliance on any single pulley, thereby extending the service life of the device.

[0025] Preferably, a reinforcing rib is provided on the back of the button, and the pulley partially protrudes from the reinforcing rib or is flush with the reinforcing rib; there is a gap between the swing rod and the reinforcing rib, or the swing rod and the reinforcing rib are in contact with each other.

[0026] The ribs on the back of the keys are another important design feature. The ribs not only enhance the structural strength of the keys, but also provide additional support for the pulley. The pulley is partially protruding from the ribs or flush with the ribs, which reduces friction between the pulley and the ribs and further improves the efficiency of the pulley's movement. At the same time, the gap or fit between the pendulum and the ribs provides the necessary space to accommodate the movement of the pendulum while ensuring sufficient contact force to maintain stable operation.

[0027] Compared with the prior art, the utility model has the following beneficial effects:

[0028] The wall switch of the utility model uses the rocker arm as the core actuator, which realizes the switching of the on / off state of the product through precise triggering with the hardware. The rocker arm can slide freely in the guide rail on the pressure plate, and the inclined setting of the guide rail further optimizes the movement trajectory of the rocker arm. This design not only improves the movement efficiency of the rocker arm, but also reduces the friction resistance during operation and prolongs the service life of the switch. The guide rail as a limiting structure for the rocker arm is a major innovation of the utility model. Through the clever design of the coordination with the guide rail, the precise control of the movement range of the rocker arm is achieved. The movement angle of the rocker arm is set to 2.4°, which not only ensures the sensitivity of the operation, but also avoids damage that may be caused by excessive swinging. This design not only improves the user's operating experience, but also ensures the stability and reliability of the switch during long-term use. BRIEF DESCRIPTION OF THE DRAWINGS

[0038] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application may be combined with each other.

[0039] The technical solution in this application will be described below in conjunction with the accompanying drawings.

[0040] The present embodiment provides a wall switch, comprising a rear seat 10, a hardware 20 installed on the rear seat 10, a swing rod 30 that triggers the hardware 20, a pressure plate 40 that limits the movement trajectory of the swing rod 30, and a button 50 connected to the swing rod 30, the pressure plate 40 is provided with an inclined guide rail 60, the swing rod 30 is provided with a guide rod 31, the guide rod 31 extends into the guide rail 60 and can move along the direction defined by the guide rail 60.

[0041] The swing arm 30, as the core actuator, realizes the switching of the on / off state of the product by precise triggering with the hardware 20. The swing arm 30 can slide freely in the guide rail 60 on the pressure plate 40, and the inclined setting of the guide rail 60 further optimizes the movement trajectory of the swing arm 30. This design not only improves the movement efficiency of the swing arm 30, but also reduces the friction resistance during operation and prolongs the service life of the switch. The guide rail 60 as a limiting structure of the swing arm 30 is a major innovation of the utility model. Through the clever design of the cooperation with the guide rail 60, the precise control of the movement range of the swing arm 30 is achieved. The movement angle of the swing arm 30 is set to 2.4°, which not only ensures the sensitivity of the operation, but also avoids damage that may be caused by excessive swinging. This design not only improves the user's operating experience, but also ensures the stability and reliability of the switch during long-term use.

[0042] The design of the guide rail 60 allows the rocker arm 30 to move accurately on a preset path, ensuring consistency in each operation and improving the reliability of the switch. Since the rocker arm 30 slides in the guide rail 60, wear is reduced and the service life of the switch is extended. The inclination angle design of the guide rail 60 takes ergonomics into consideration, so that the user can easily activate the rocker arm 30 when pressing the button 50 without applying excessive force. The compact design of the guide rail 60 enables the switch to adapt to different installation environments and work properly even in limited space, which is conducive to making the switch thinner and improving the aesthetics of the product. Through the guidance of the guide rail 60, the movement of the rocker arm 30 is more stable, which reduces misoperation caused by external force or vibration and improves the stability of the product.

[0043] In this embodiment, the guide rail 60 includes a first inclined groove 61 and a second inclined groove 62 dug on the first side of the pressure plate 40, and the first inclined groove 61 and the second inclined groove 62 are arranged in an inverted figure eight shape. The guide rail 60 also includes a third inclined groove 63 and a fourth inclined groove 64 dug on the second side of the pressure plate 40, and the third inclined groove 63 and the fourth inclined groove 64 are arranged in an inverted figure eight shape, and the second side is the opposite side of the first side.

[0044] The design of the guide rail 60 adopts four inclined grooves, namely the first inclined groove 61, the second inclined groove 62, the third inclined groove 63 and the fourth inclined groove 64, which are arranged in an inverted eight-shaped manner. This design not only improves the stability of the overall structure, but also optimizes the guide effect. Specifically, the inverted eight-shaped arrangement of the first inclined groove 61 and the second inclined groove 62 and the third inclined groove 63 and the fourth inclined groove 64 enables the guide rod 31 to disperse the pressure more effectively during the sliding process, reducing the wear or damage caused by the concentrated pressure. This design not only improves the durability of the guide rail 60, but also extends the service life of the equipment. At the same time, the inverted eight-shaped arrangement increases the contact area between the guide rod 31 and the pressure plate 40, thereby improving the guide efficiency and reducing the friction resistance. This means that under the same working conditions, the equipment can operate more energy-efficiently and improve the work efficiency. In addition, this design of the guide rail 60 also has good adaptability and can be adjusted according to different working environments and working requirements. For example, by changing the angle or width of the inclined groove, it can adapt to guide rods 31 of different sizes and shapes, so that the equipment can flexibly cope with various working conditions.

[0045] In this embodiment, the number of the guide rods 31 is four, corresponding to the first inclined slot 61 , the second inclined slot 62 , the third inclined slot 63 and the fourth inclined slot 64 , respectively.

[0046] In this embodiment, four guide rods 31 are selected as the supporting elements of the guide rail 60, and each guide rod 31 corresponds to the four inclined grooves on both sides of the pressure plate 40. This design has significant advantages. The uniform distribution of the four guide rods 31 can ensure that the guide rail 60 can provide uniform support force in all directions. In practical applications, the operation of the equipment is often affected by forces from different directions. If the support force is unbalanced, it may cause the equipment to run unsteadily, and even cause problems such as vibration or noise. The design of the four guide rods 31 in the utility model can ensure that the guide rail 60 can provide uniform support force under any circumstances, thereby ensuring the stable operation of the equipment. This design can reduce the wear of the equipment caused by unbalanced support. During the operation of the equipment, if the pressure on a certain part is too large, it may cause the wear of the part to increase. The design of the four guide rods 31 in the utility model can effectively reduce the wear of the equipment caused by unbalanced support by evenly distributing the support force, thereby extending the service life of the equipment. This design also has a certain degree of flexibility. In practical applications, some special working conditions or requirements may be encountered, and the support mode of the guide rail 60 needs to be adjusted. The four guide rods 31 in this embodiment can be easily adjusted or replaced to adapt to different working conditions and requirements due to their simple structure.

[0047] In this embodiment, the guide rod 31 is cylindrical in shape.

[0048] The cylindrical appearance design of the guide rod 31 not only gives the product a simple and elegant appearance, but also shows significant advantages in function. From the perspective of structure and manufacturing, the design of the cylindrical guide rod 31 simplifies the production process. Due to the regularity of its geometric shape, the processing difficulty in the manufacturing process is relatively low, and it can be produced quickly and efficiently through standardized production means. This standardized production method not only reduces the manufacturing cost, but also improves the production efficiency, making the product more competitive in the market. From the perspective of mechanical properties, the cylindrical guide rod 31 can more effectively disperse the pressure when subjected to external force. Its surface is evenly stressed, avoiding the occurrence of local stress concentration, thereby improving the durability of the guide rod 31. During long-term use, the cylindrical guide rod 31 can resist wear and fatigue and maintain stable performance, which is crucial to ensure the long-term stable operation of the equipment. In practical applications, the stability of the guide rod 31 is directly related to the smoothness and reliability of the equipment operation. The cylindrical guide rod 31 can provide a more stable guiding effect during the sliding process, reducing the swing or deflection caused by irregular shape. This stability not only improves the working efficiency of the equipment, but also reduces the potential risk of failure caused by unstable movement. This advantage is particularly obvious under high-speed movement or complex working conditions, which can significantly improve the overall performance of the equipment. In addition, the cylindrical guide rod 31 also has good versatility and adaptability. Due to the versatility of its shape, it can be easily used in conjunction with other circular or nearly circular parts, improving the compatibility of the product. Whether in a compact space or in a complex mechanical structure, the cylindrical guide rod 31 can play its due role and meet diverse application requirements.

[0049] In this embodiment, the pressing plate 40 is installed on the rear seat 10 . The pressing plate 40 is connected to a bracket 70 . A frame 80 is connected to the bracket 70 . The frame 80 is located at the periphery of the button 50 .

[0050] The design of the pressure plate 40 is also very clever. The pressure plate 40 is installed on the rear seat 10 and connected to it through the bracket 70, which not only ensures the stability of the pressure plate 40, but also facilitates adjustment and maintenance. The frame 80 on the bracket 70 is located on the periphery of the button 50, forming a clear boundary, which is convenient for users to locate and operate. This design not only improves the user experience, but also makes the appearance of the switch product more beautiful.

[0051] In this embodiment, a pulley 90 for connecting the swing rod 30 and the button 50 is further provided between the swing rod 30 and the button 50. The pulley 90 is rotationally connected to the button 50, and the pulley 90 and the swing rod 30 are in point contact or line contact.

[0052] The design of the pulley 90 between the swing rod 30 and the button 50 is a highlight of the present invention. The pulley 90 is rotatably connected to the button 50, so that the movement of the swing rod 30 can be smoothly transmitted to the button 50, achieving precise control. The contact mode between the pulley 90 and the swing rod 30 can be point contact or line contact. This flexibility allows the designer to choose the most appropriate contact mode according to specific needs to optimize the movement performance and reduce wear. Point contact can provide less friction resistance, while line contact can provide a larger contact area and increase stability.

[0053] In this embodiment, a slot 51 is disposed on the back of the button 50 , and a rotating shaft 91 is disposed axially of the pulley 90 , and the rotating shaft 91 is rotatably engaged in the slot 51 .

[0054] The design of the slot 51 arranged on the back of the key 50 and the shaft 91 arranged axially of the pulley 90 greatly improves the adjustability and stability of the device. The slot 51, as a key structure for fixing the position of the pulley 90, ensures that the pulley 90 will not shift during operation, thereby ensuring the accuracy and repeatability of the action of the key 50. The setting of the shaft 91 allows the pulley 90 to rotate freely in the slot 51. This design not only facilitates the installation and removal of the pulley 90, but also ensures the smooth movement of the pulley 90 and reduces the wear caused by friction.

[0055] In this embodiment, there are one or more pulleys 90 , and the plurality of pulleys 90 are evenly distributed on the back side of the key 50 .

[0056] The number of pulleys 90 can be one or more. When multiple pulleys 90 are evenly distributed on the back of the key 50, the operation sensitivity and response speed of the key 50 can be further improved. This design enables the pulleys 90 to distribute pressure more evenly when subjected to force, reduces excessive reliance on any single pulley 90, and thus extends the service life of the device.

[0057] In this embodiment, a reinforcing rib 52 is provided on the back of the button 50, and the pulley 90 partially protrudes from the reinforcing rib 52 or is flush with the reinforcing rib 52; there is a gap between the swing rod 30 and the reinforcing rib 52, or the swing rod 30 and the reinforcing rib 52 fit each other.

[0058] The reinforcing rib 52 disposed on the back of the key 50 is another important design feature. The reinforcing rib 52 not only enhances the structural strength of the key 50, but also provides additional support for the pulley 90. The pulley 90 partially protrudes from the reinforcing rib 52 or is flush with the reinforcing rib 52. This design can reduce the friction between the pulley 90 and the reinforcing rib 52, further improving the movement efficiency of the pulley 90. At the same time, the design of a gap or mutual fit between the swing rod 30 and the reinforcing rib 52 provides the necessary space to accommodate the movement of the swing rod 30, while ensuring sufficient contact force to maintain stable operation.

[0059] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
