Description

Technical Field

[0001] This utility model relates to the field of switching equipment technology, and more specifically, to a rotary drive component. Background Technology

[0002] Existing rotary switches are widely used in various electrical appliances, such as lamps, power switches, electric ovens, electric stoves, and gas stoves, to switch the device on and off or to change different functions by rotating it. Traditional rotary switches mostly adopt a cylindrical structure with several sets of terminals symmetrically arranged along the circumference of the cylinder. Rotating the knob of the rotary switch causes the moving contact to connect with different sets of terminals to achieve the switching of the device on and off and the changing of different settings. However, the contact method between the terminals and the moving contact of this type of rotary switch has the problem of insufficient reliability. Specifically, frequent rotation of the rotary switch over a long period of time will cause oxidation or wear on the surface of the moving contact, increasing the contact resistance and causing safety problems such as overheating, unstable signal, or even open circuit; while frequent use over a long period of time will also cause the terminals to loosen, resulting in poor contact.

[0003] Furthermore, excessive force applied to the rotary switch can cause excessive contact between the terminal block and the moving contact, leading to excessive wear and deformation of both. This results in a loose fit between the moving contact and the terminal block, affecting connection stability. Excessive force applied to the terminal block during rotation can also cause cracks in the terminal housing, reducing insulation performance and increasing the risk of short circuits or leakage. Additionally, the traditional rotary switch's cylindrical structure and the multiple sets of terminals around it present challenges in terms of overall compactness and production efficiency.

[0004] In view of this, it is necessary to design a rotary drive that is suitable for various rotary switch structures, can provide good connection stability, and can make the layout of rotary switches more compact. It is suitable for rotary switches with various structural layouts, which is convenient for production and saves costs. Utility Model Content

[0054] The core of this utility model lies in providing a rotary drive component that is applicable to various rotary switch structures, provides good connection stability, and enables a more compact layout of the rotary switch. It is suitable for rotary switches with various structural layouts, facilitating production and saving costs.

[0055] Please see Figure 1 , Figure 1 This is a schematic diagram of the structure of a rotary drive component according to an embodiment of the present invention. The present invention provides a rotary drive component, including a rotary member 1 and a drive member 2, wherein the drive member 2 is fixedly connected to the rotary member 1, and the drive member 2 has at least one end fixedly connected to the rotary member 1; and at least one rotary protrusion is provided on the drive member 2.

[0056] In one specific embodiment, the rotary drive component provided by this utility model is as follows: Figure 1 As shown, the rotary drive includes a rotating component 1 and a driving component 2. The driving component 2 has an end 210 fixedly connected to the rotating component 1, so that rotating the rotating component 1 causes the driving component 2 to rotate synchronously. The rotating component 1 is circular, but this invention is not limited thereto. The driving component 2 is also provided with a rotating protrusion 220, which is square, but this invention is not limited thereto. When the rotary drive is applied in a rotary switch structure, rotating the rotating component 1 clockwise or counterclockwise causes the driving component 2 to rotate synchronously, thereby causing the rotating protrusion 220 to rotate and drive other components within the rotary switch that contact and engage with the rotating protrusion 220. These components include levers, gears, connecting rods, cams, racks, conductive metal sheets, etc., and this invention is not limited thereto.

[0057] In this embodiment of the invention, a driving component 2 is fixedly connected to the rotating component 1, and the driving component 2 is further provided with a rotating protrusion 220. This physical protrusion structure provides better connection stability and is less prone to deformation, thereby realizing the opening and closing functions of the rotary switch. This avoids the problem of poor contact at the rotary switch terminals caused by prolonged use or excessive force, enhancing the reliability of the rotary driving component. Furthermore, the rotary driving component is easy to install and can be manufactured using assembly line production or 3D printing processes. It is suitable for different rotary switch structures, saving materials while improving production efficiency and reducing manufacturing costs.

[0058] In a preferred embodiment, the number of ends of the driving member 2' that are fixedly connected to the rotating member 1 is two.

[0059] Please refer to 4. Figure 4 This is a schematic diagram of the structure of a rotary drive component according to another embodiment of the present invention.

[0060] In one specific embodiment, the rotary drive component provided by this utility model is as follows: Figure 4 As shown, the driving member 2' has two ends 210' and 211' that are fixedly connected to the rotating member 1, so that when the rotating member 1 is rotated, the driving member 2' can be more stably connected to the rotating member 1 and rotate synchronously with the rotating member 1. Specifically, one end 211' of the driving member 2' is fixedly connected to the left side of the rotating member 1, and one end 210' of the driving member 2' is fixedly connected to the right side of the rotating member 1, but this utility model is not limited thereto. By setting both ends of the driving member 2' to be fixedly connected to the rotating member 1, better connection stability and reliability between the rotating member 1 and the driving member 2' can be provided.

[0061] In a preferred embodiment, there are two rotating protrusions, 220 and 230, which are spaced apart from each other on the drive member 2.

[0062] Please refer to the following: Figure 1 and Figure 4 In one specific embodiment, the driving component 2 is provided with two rotating protrusions 220 and 230, which are spaced apart from each other on the driving component 2. Specifically, the rotating protrusion 220 is located on the left side of the driving component 2, and the rotating protrusion 230 is located on the right side of the driving component 2. The rotating protrusion 220 is square, and the rotating protrusion 230 is arc-shaped, but this utility model is not limited thereto. When the rotating driving component is applied in a rotary switch structure, rotating the rotating component 1 clockwise or counterclockwise can cause the driving component 2 to rotate synchronously, thereby causing the rotating protrusions 220 and 230 to rotate and drive other components inside the rotary switch that are in contact with the rotating protrusions 220 and 230. The components inside the rotary switch that are in contact with the rotating protrusions 220 and 230 include levers, gears, connecting rods, cams, racks, conductive metal sheets, etc., and this utility model is not limited thereto. It should be noted that when rotating the rotating component 1 to cause the driving component 2 to rotate, the rotating protrusions 220 and 230 can simultaneously drive other components within the rotary switch to rotate, or they can drive other components within the rotary switch to rotate sequentially depending on the different layout structures within the rotary switch. Furthermore, when the driving component 2 rotates, the rotating protrusion 220 first drives one component within the rotary switch to rotate, thus activating the first functional position of the rotary switch. As the rotating component 1 continues to rotate, the rotating protrusion 230 of the driving component 2 then drives another component within the rotary switch to rotate, thus activating the second functional position of the rotary switch. However, this invention is not limited to this. Figure 4 The structural shape, working principle, and beneficial technical effects of the two rotating protrusions 220' and 230' provided on the driving component 2' in the embodiment are the same as those of the rotating protrusions 220 and 230 in the embodiment of the driving component 2, and will not be repeated here.

[0063] In this embodiment of the invention, by setting multiple rotating protrusions, the rotary switch can be adjusted to multiple positions to meet the increasing functional selection needs of the device.

[0064] In a preferred embodiment, the driving components 2”, 2”' further include first driving components 21”, 21”' and second driving components 22”, 22”', wherein the first driving components 21”, 21”' and the second driving components 22”, 22”' are separate structures; wherein.

[0065] The first driving members 21” and 21”' have at least one end fixedly connected to the rotating member 1, and the second driving members 22” and 22”' have at least one end fixedly connected to the rotating member 1; and,

[0066] There are two rotating protrusions, which are respectively disposed on the first driving member 21”, 21”' and the second driving member 22”, 22”'.

[0067] Please see Figure 7 , Figure 7 This is a schematic diagram of the structure of a rotary drive component according to another embodiment of the present invention.

[0068] In one specific embodiment, the driving component 2” further includes a first driving component 21” and a second driving component 22”, which are separate structures. The first driving component 21” and the second driving component 22” each have an end fixedly connected to the rotating component 1. Specifically, the first driving component 21” is located on the right side of the rotating component 1 and has an end 210” fixedly connected to the rotating component 1, while the second driving component 22” is located on the left side of the rotating component 1 and has an end 221” fixedly connected to the rotating component 1. However, this invention is not limited to this. The number of rotating protrusions is two, respectively located on the first driving component 21” and the second driving component 22”. Specifically, the first driving component 21”... The first drive component 2" is provided with a rotating protrusion 211", which is arc-shaped; the second drive component 22" is provided with a rotating protrusion 220", which is square. There is a gap between the rotating protrusions 211" and 220", but this utility model is not limited thereto. When the rotating drive component is applied in the rotary switch structure, rotating the rotating component 1 clockwise or counterclockwise can make the drive component 2" rotate synchronously, thereby making the rotating protrusions 211" and 220" rotate, thereby driving other parts in the rotary switch that are in contact with the rotating protrusions 211" and 220". The parts in the rotary switch that are in contact with the rotating protrusions 211" and 220" include levers, gears, connecting rods, cams, racks, conductive metal sheets, etc., and this utility model is not limited thereto. It should be noted that when rotating the rotating component 1 to rotate the driving component 2", the rotating protrusion 211" and the rotating protrusion 220' can simultaneously drive other components inside the rotary switch to rotate, or they can drive other components inside the rotary switch to rotate sequentially depending on the different layout structures inside the rotary switch. Furthermore, when the driving component 2 rotates, the rotating protrusion 211" first drives one component inside the rotary switch to rotate, thus opening the first functional position of the rotary switch. When the rotating component 1 continues to rotate, the rotating protrusion 220" of the driving component 2" then drives another component inside the rotary switch to rotate, thus opening the second functional position of the rotary switch. However, this invention is not limited to this.

[0069] In this embodiment of the invention, by setting a split-structure driving component 2", the first driving component 21" and the second driving component 22" are respectively fixedly connected to the rotating component 1. This ensures the connection stability of the driving component 2" while freeing up more space inside the rotating component 1, making the rotary drive suitable for rotary switches with more layout structures. At the same time, the split-structure driving component 2" can further save material, reduce manufacturing costs, simplify the manufacturing process, and improve manufacturing efficiency. In addition, by setting multiple rotating protrusions, multi-level adjustment of the rotary switch can be realized to meet the increasing functional selection needs of the equipment.

[0070] In a preferred embodiment, the number of ends of the first driving member 21”' or the second driving member 22”' that are fixedly connected to the rotating member 1 is two.

[0071] Please see Figure 10 , Figure 10 This is a schematic diagram of the structure of a rotary drive component according to another embodiment of the present invention.

[0072] In one specific embodiment, the driving component 2”' further includes a first driving component 21”' and a second driving component 22”', which are separate structures. The first driving component 21”' has two ends fixedly connected to the rotating component 1, and the second driving component 22”' has one end fixedly connected to the rotating component 1. Specifically, the first driving component 21”' is located on the right side of the rotating component 1, with one end 210”' fixedly connected to the right side of the rotating component 1, and the other end 215”' fixedly connected to the upper side of the rotating component 1. The second driving component 22”' is located on the left side of the rotating component 1 and has one end 221”' fixedly connected to the rotating component 1, but this is not a limitation of the present invention. The rotating protrusions are two in number, respectively located on the first driving component 21”' and the second driving component 22”'. Specifically, the first driving member 21”' is provided with a rotating protrusion 211”', which is arc-shaped; the second driving member 22”' is provided with a rotating protrusion 220”', which is square. There is a gap between the rotating protrusion 211”' and the rotating protrusion 220”', but the present invention is not limited thereto. Figure 10 The structural shape, working principle and beneficial technical effects of the two rotating protrusions 211”” and 220”” provided on the driving component 2”” in the embodiment are the same as those of the rotating protrusions 211”” and 220” in the embodiment of the driving component 2”, and will not be repeated here.

[0073] In this embodiment of the present invention, by setting the two ends 210”' and 215”' of the first driving component 21”' to be fixedly connected to the rotating component 1, the connection stability of the first driving component 21”' is further enhanced. This allows the rotating component 1 to be rotated in the rotary switch, causing the rotating protrusion 211”' of the first driving component 21”' to drive the heavy components to rotate, thus avoiding damage or deformation of the first driving component 21”', improving the service life of the rotary driving component and the reliability of the rotary switch.

[0074] In a preferred embodiment, the rotary drive further includes a flexible elastic element 3, one end 31 of which is disposed on the drive members 2, 2', 2”, 2”'. The drive members 2, 2', 2”, 2”' are provided with limiting grooves 240, 240', 212”, 212”' or limiting posts 250, 250', 213”, 213”' corresponding to the flexible elastic element 3, and the end 31 of the flexible elastic element is disposed on the limiting grooves 240, 240', 212”, 212”' or limiting posts 250, 250', 213”, 213”'.

[0078] As described in the above embodiments, the rotary drive component is further provided with a flexible elastic element 3. One end 31 of the flexible elastic element 3 is disposed on the drive components 2 and 2' and located between the rotary protrusions 220 and 220' and the rotary protrusions 230 and 230'. The difference from the above embodiments is that, in this embodiment, the drive components 2 and 2' are provided with limiting posts 250 and 250' corresponding to the end 31 of the flexible elastic element 3. The end 31 of the flexible elastic element 3 is sleeved on the limiting posts 250 and 250', so that the flexible elastic element 3 is fixedly connected to the drive components 2 and 2' and does not detach. However, this utility model is not limited thereto.

[0079] Please refer to the following: Figure 8 and Figure 11 , Figure 8 for Figure 7 Schematic diagrams of the rotary drive component and flexible elastic component in the embodiment. Figure 11 for Figure 10 A schematic diagram of the rotating drive component and the flexible elastic component in the embodiment.

[0080] In one specific embodiment, the rotary drive component is provided with a flexible elastic element 3, one end 31 of which is disposed on the drive components 2”, 2”'. Specifically, the end 31 of the flexible elastic element 3 is disposed on the first drive components 21”, 21”' and located between the rotating protrusions 211”, 211”' and the rotating protrusions 220”, 220”'. The drive components 2”, 2”' are also provided with limiting grooves 212”, 212”' corresponding to the end 31 of the flexible elastic element 3. The end 31 of the flexible elastic element 3 is disposed in the limiting grooves 212”, 212”', so that the flexible elastic element 3 remains movable and abuts against the drive components 2”, 2”' without disengaging, but the present invention is not limited thereto.

[0081] Please refer to the following: Figure 9 and Figure 12 , Figure 9 for Figure 7 Schematic diagrams of the rotary drive component and torsional elastic component in the embodiment. Figure 12 for Figure 10 A schematic diagram of the structure of the rotary drive and torsional elastic element in the embodiment.

[0082] As described in the above embodiments, the rotary drive component is further provided with a flexible elastic element 3. One end 31 of the flexible elastic element 3 is disposed on the first drive component 21”, 21”’ of the drive components 2”, 2”’, and the flexible elastic element 3 is located between the rotating protrusions 211”, 211”’ and the rotating protrusions 220”, 220”’. The difference from the above embodiments is that, in this embodiment, the drive components 2”, 2”’ are provided with limiting posts 213”, 213”’ corresponding to the end 31 of the flexible elastic element 3. The end 31 of the flexible elastic element 3 is sleeved on the limiting posts 213”, 213”’, so that the flexible elastic element 3 is fixedly connected to the drive components 2”, 2”’ and does not detach. However, this utility model is not limited to this. The flexible elastic element is a limiting spring, but this utility model is not limited to this.

[0083] In this embodiment of the invention, by providing a flexible elastic element 3 on the rotary drive component, and having the end 31 of the flexible elastic element 3 positioned in the limiting grooves 240, 240', 212", 212"', the rotary drive component can provide a good tactile feel and improve operational convenience when configured in a rotary switch. Specifically, the other end of the flexible elastic element 3 can be movably or fixedly positioned in other structures within the rotary switch, such as the rotary switch housing, base, or baffle. When the rotary drive component is rotated, the end 31 of the flexible elastic element 3 rotates asynchronously with the other end of the flexible elastic element 3, causing the flexible elastic element 3 to be stretched or compressed and deformed, thereby providing a good rotary feel through the spring contraction force, without any play. Furthermore, when the end 31 of the flexible elastic element 3 is positioned on the limiting posts 250, 250', 213", 213"', the other end of the flexible elastic element 3 can also be movably or fixedly positioned in other structures within the rotary switch, providing a good rotary feel through the same working principle as described above. The different structures of the limiting grooves 240, 240', 212”, 212”' and the limiting posts 250, 250', 213”, 213”' further improve the application scenarios of the rotary drive and expand the applicability of the rotary drive.

[0084] In a preferred embodiment, the rotary drive further includes a torsional elastic member 4, and the drive members 2, 2', 2”, 2”' are also provided with abutment portions 260, 260', 214”, 214”', and one end 41 of the torsional elastic member 4 abuts against the abutment portions 260, 260', 214”, 214”'.

[0085] Please refer to this again. Figure 3 , Figure 6 , Figure 9 and Figure 12 In one specific embodiment, the rotary drive component is further provided with a torsional elastic element 4. Specifically, as shown in the figure... Figure 3 and Figure 6As shown, the driving components 2 and 2' are provided with abutment portions 260 and 260' corresponding to the torsional elastic member 4. One end 41 of the torsional elastic member 4 abuts against the abutment portions 260 and 260'. The torsional elastic member 4 is located between the rotating protrusions 220 and 220' and the rotating protrusions 230 and 230', but this utility model is not limited thereto. In addition, as Figure 9 and Figure 12 As shown, in one specific embodiment, the torsional elastic element 4 is disposed on the first driving member 21”, 21”’ of the driving member 2”, 2”’. Specifically, the first driving member 21”, 21”’ is provided with abutting portion 214”, 214”’ corresponding to the torsional elastic element 4, and one end 41 of the torsional elastic element 4 abuts against the abutting portion 214”, 214”’. The torsional elastic element 4 is located between the rotating protrusions 211”, 211”’ and the rotating protrusions 220”, 220”’. The torsional elastic element 4 is a torsion spring, but the present invention is not limited thereto.

[0086] In this embodiment of the invention, by abutting the end 41 of the torsional elastic member 4 against the abutment portions 260, 260', 214", and 214"', the rotational force of the rotary drive member in the rotary switch is further enhanced and the jerking sensation is reduced. Simultaneously, after rotating the rotary drive member, the rotary switch is reset by the torque of the torsional elastic member. Specifically, the other end of the torsional elastic member 4 can be movably or fixedly disposed in other structures within the rotary switch, such as the rotary switch housing, base, or baffle. When the rotary drive member is rotated, the torsional elastic member 4 is rotated first to enhance the feel of the rotary switch during rotation and reduce jerking sensation. After rotation, the rotary switch can return to its pre-rotation position without applying force due to the rotational force generated by the rotation of the torsional elastic member 4 in the opposite direction of rotation. This makes the rotary switch equipped with the rotary drive member suitable for safety control equipment or emergency stop devices requiring automatic reset. It should be noted that the rotating component 1 and the driving components 2, 2', 2”, 2”' in this utility model are made of one or more of metal, nylon, POM (polyoxymethylene) plastic, and PC (polycarbonate) plastic, but this utility model is not limited to these.

[0087] The rotary drive component provided by this utility model, by fixing drive components 2, 2', 2”, 2”' to the rotating component 1, and further provided with rotating protrusions 220, 230, 211”, 211”' on the drive components 2, 2', 2”', can realize the opening and closing function of the rotary switch with a physical protrusion structure that has better connection stability and is not easily deformed. In contrast, the rotating structure inside the rotary switch in the prior art has problems such as low connection stability, easy deformation of the moving contact leading to short service life, insufficient contact point reliability, and low compactness of structural layout and production efficiency. Therefore, the rotary drive component provided by this utility model can be applied to various rotary switch structures, while providing good connection stability and enabling a more compact layout of the rotary switch. It is suitable for rotary switches with various structural layouts, facilitating production and saving costs. From the perspective of manufacturing process, the rotary drive component with drive component 2 can save 30.5% of material compared to the rotary drive component with drive component 2'. In terms of structural layout, the driving components 2, 2', 2”, and 2”' can achieve the same rotational driving function through different structures, making the rotation of the rotating drive component smoother and without any jerking.

[0089] Of course, there may be other embodiments of this utility model. Without departing from the spirit and essence of this utility model, those skilled in the art can make various corresponding changes and modifications based on this utility model, but these corresponding changes and modifications should all fall within the protection scope of the appended claims of this utility model.
