Description

Technical Field

[0001] This invention relates to the field of low-voltage electrical equipment, and in particular to a drive for a switching device, and a switching device having the drive. Background Technology

[0002] Currently, most existing switch devices connect their buttons directly to their internal swing mechanisms to drive the opening and closing of the internal conductive components. In this structure, the rotation angle of the button matches the swing angle of the swing mechanism, which limits the overall thickness of the switch device. This requires a significant thickness both inside and outside the wall, restricting its aesthetic appearance.

[0003] Although some existing designs propose placing a rocker arm on each side of the oscillating structure, and operating the oscillating structure by pressing the rocker arm with a button, thereby enabling the button to drive the oscillating structure to swing at a larger angle with a smaller rotation angle, thus reducing the thickness of the switching device, these designs are inconvenient to manufacture and assemble, and have poor reliability. Summary of the Invention

[0004] The purpose of this invention is to provide a driving component that can reduce the rotation angle of the switch button without reducing the swing amplitude of the swing structure, and is easy to manufacture and assemble, and has high reliability.

[0005] Another object of the present invention is to provide a switching device including such a driving element, which has a small overall thickness, is easy to manufacture and assemble, and has high reliability.

[0006] This invention provides a driving component for a switching device, the switching device including a button and a swing structure. The driving component is disposed between the button and the swing structure, and can drive the swing structure to swing under the pressure of the button, thereby connecting or disconnecting the circuit of the switching device. The driving component includes at least two driving bodies, a connecting body, and at least two elastic connecting parts. At least one driving body is provided at each end of the connecting body. The elastic connecting parts connect the driving bodies and the connecting body. The driving component of this invention can reduce the rotation angle of the button, thereby reducing the overall thickness of the switching device, and it can be quickly assembled in the switching device.

[0007] In another illustrative embodiment of the driving component of the present invention, the driving body includes a rotating shaft, and under the drive of the button, the driving body can be supported on the switching device via the rotating shaft and rotate accordingly.

[0008] In another illustrative embodiment of the driving component of the present invention, the driving body includes a pressing part and a driving part. When the button is pressed, the pressing part can drive the driving body to rotate. The driving part can drive the oscillating structure to oscillate.

[0009] In another illustrative embodiment of the driving component of the present invention, the distance between the pressing part and the rotating shaft is less than the distance between the driving part and the rotating shaft. Optionally, the pressing part is located between the rotating shaft and the driving part. Since the distance between the pressing part and the rotating shaft is less than the distance between the driving part and the rotating shaft, when the driving body rotates, the stroke of the pressing part is less than the stroke of the driving part, which allows the swing structure to be driven by a smaller rotation angle of the button with a larger swing angle.

[0010] In another illustrative embodiment of the driving element of the present invention, one of the driving bodies is connected to the connecting body via one or both of the elastic connecting portions.

[0011] In another illustrative embodiment of the driving component of the present invention, the elastic connection portion includes an extension arm and at least one elastic arm. One end of the extension arm is connected to the connecting body. The two ends of the elastic arm are respectively connected to the other end of the extension arm and a driving body.

[0012] In another illustrative embodiment of the driving element of the present invention, one of the extension arms connects to two of the elastic arms, enabling multiple driving elements to be arranged within the limited space of the switching device.

[0013] In another illustrative embodiment of the drive component of the present invention, the elastic connection portion further includes a support block, which extends from the extension arm toward the functional module of the switching device and is used to support the extension arm. When the drive body rotates, the elastic arm to which it is connected deforms. Because a support block is provided on the extension arm, the deformation of the elastic arm will not interfere with the other elastic arm on the extension arm to which it is connected.

[0014] In another illustrative embodiment of the drive component of the present invention, the elastic arm includes a bent section such that the rotation axis of the drive body is parallel to the rotation axis of the swing structure. Furthermore, providing the bent section allows for more deformation space for the elastic connection.

[0015] In another illustrative embodiment of the driving component of the present invention, the connecting body is provided with at least one positioning part.

[0016] In another illustrative embodiment of the driving component of the present invention, the positioning part is a positioning groove, a positioning post, or a buckle.

[0017] In another illustrative embodiment of the drive component of the present invention, an opening is provided in the middle of the connecting body. The swing structure of the switching device can extend from the opening, thereby reducing the overall thickness of the switching device.

[0018] In another illustrative embodiment of the driving component of the present invention, the driving component is integrally formed.

[0019] The present invention also provides a switching device, including a button, a functional module, and a driving component according to any of the above embodiments. The driving component is capable of rotating under the drive of the button and driving the oscillating structure in the functional module to oscillate. This switching device has a small overall thickness, is easy to manufacture and assemble, and has high reliability.

[0020] In another illustrative embodiment of the switching device of the present invention, the switching device includes a pressure plate, and the driving member is detachably connected to the side of the pressure plate facing the functional module. By detachably connecting the driving member to the pressure plate, the assembly of the switching device can be facilitated. Attached Figure Description

In the drawings, the same reference numerals indicate components with the same or similar structures but the same function.

[0036] In this document, terms such as "first" and "second" do not indicate their importance or order, but are only used to distinguish them to facilitate the description of the document.

[0037] To keep the drawings concise, only the parts relevant to the invention are shown schematically in each figure, and they do not represent the actual structure of the product. Furthermore, for ease of understanding, in some figures, only one of the components with the same structure or function is shown schematically, or only one is labeled.

[0038] See Figure 1 The diagram shows an exploded structural schematic of one embodiment of the switching device of the present invention. The switching device includes a button 10, a pressure plate 20, a driving component 30, a functional module 40, and a mounting bracket 50. The number of buttons 10 can be one, two, three, four, or other quantities. Figure 1 In the case where three buttons are provided, namely button 11, button 12, and button 13, the functional module 40 includes a swing structure that can drive the circuit of the switching device to be turned on and off. The driving member 30 can drive the swing structure to swing under the action of button 10. The driving member 30 includes a connecting body, a driving body, and an elastic connecting part connecting the connecting body and the driving body. The driving member 30 is detachably connected to the side of the pressure plate 20 facing the functional module 40. Alternatively, the switching device may not have a pressure plate 20, but the driving member 30 may be detachably connected to the functional module 40, or other methods may be used, which are not limited here. Specifically, a positioning part 311 may be provided on the connecting body 31 of the driving member 30. The positioning part 311 may be a positioning groove, a positioning post, a buckle, or other methods. This integrated design of the driving member facilitates production and assembly, and can reduce the overall thickness of the switching device.

[0039] See Figure 2This diagram illustrates a schematic embodiment of the driving component of the present invention. The driving component 30 can be used in a three-button switch. The driving component 30 can be integrally formed and includes a connecting body 31, four elastic connecting parts 32, and six driving bodies 33. The driving bodies 33 are connected to the connecting body 31 via the elastic connecting parts 32. Specifically, the driving body 33 can be connected to the connecting body via one elastic connecting part 32 or two elastic connecting parts 32. Under the actuation of the button, the driving body 33 can rotate and drive the oscillating structure to oscillate.

[0040] The connecting body 31 may be provided with a positioning part 311 for positioning the driving member 30 in the switching device. Specifically, the positioning part 311 may be a positioning slot, and a positioning post may be provided on the pressure plate. The driving member 30 is positioned in the switching device by the cooperation of the positioning slot and the positioning post. An opening 312 is provided in the middle of the connecting body 31 to accommodate the end of the swing structure, thereby reducing the overall thickness of the switching device.

[0041] The driving body 33 includes a rotating shaft 331, a pressing part 332, and a driving part 333. Driven by the button, the driving body 33 can be supported on the switch device via the rotating shaft 331 and rotate accordingly. The pressing part 332 can drive the driving body 33 to rotate, thereby the driving part 333 drives the swing structure 41 to swing. The driving body 33 can be as follows: Figure 2 They are positioned on both sides of the connecting body 31.

[0042] like Figure 2 As shown, the pressing part 332 is located between the rotating shaft 331 and the driving part 333. When the driving body 33 rotates, the pressing part 332 and the driving part 333 have the same rotation angle. However, since the distance between the pressing part 332 and the rotating shaft 331 is smaller than the distance between the driving part 333 and the rotating shaft 331, the stroke of the driving part 333 is greater than the stroke of the pressing part 332. The driving body 33 can amplify the stroke of the button rotation and transmit it to the inside of the switching device, thereby reducing the overall thickness of the switching device. Alternatively, the pressing part 332 and the driving part 333 can be provided on both sides of the rotating shaft 331.

[0043] Figure 2 Each elastic connection 32 may further include an extension arm 321 and an elastic arm 322. One end of the extension arm 321 is connected to the connection body 31. The two ends of the elastic arm 322 are respectively connected to the other end of the extension arm 321 and a drive body 33. Figure 2 As shown, if it is necessary to connect two linkages 33 in one elastic connection 32, two elastic arms 322 can be connected to the end of one extension arm 321.

[0044] See Figure 3 It shows Figure 2A schematic diagram of the drive component from another perspective. The elastic connection portion 32 also includes a support block 3211. This support block 3211 is formed by the extension arm 321 extending towards the functional module 40 of the switching device and can be used to support the extension arm 321. Since the extension arm 321 is supported by the support block 3211 on the functional module 40, it will not deform due to the rotation of the drive body 33. Therefore, when one elastic arm 322 connected to it deforms due to the rotation of its corresponding drive body 33, the elastic arm 322 will not interfere with the other elastic arm 322 connected to the extension arm 321, so as to maintain the independence between adjacent drive bodies 33. The elastic arm 322 may also include a bent section 3221, which enables the rotation axis of the drive body 33 to be parallel to the rotation axis of the swing structure 41 and provides a larger space for the deformation of the elastic arm 322.

[0045] Apart from Figure 2 , Figure 3 Besides the driving element 30 shown, the driving element of the present invention may also take other forms, which are not limited here. For example, two driving elements may be symmetrically arranged on both sides of the driving element connecting body, and each driving element is connected to the connecting body through one or two elastic connecting parts; four driving elements may be symmetrically arranged on both sides of the driving element connecting body, and each driving element is connected to the connecting body through one or two elastic connecting parts; eight driving elements may be symmetrically arranged on both sides of the driving element connecting body, and each driving element is connected to the connecting body through one or two elastic connecting parts.

[0046] See Figure 4 It shows along Figure 1 A cross-sectional view of the swing structure below the switch button 11, taken perpendicular to the axis of rotation of the swing structure. A drive unit 30 is assembled between the button 11 and the swing structure 41. When the button 11 is rotated, the drive body 33 corresponding to the pressed side of the button 11 rotates around the axis 331 of the drive body 33 toward the functional module 40 to transmit the rotation of the button 11 to the swing structure 41. When the button 11 rotates, the stroke of its first part acting on the pressing part 332 is less than the stroke of the swing structure 41 acting on the second part of the drive end 333; the distance between the first part and the axis of rotation of the button 11 is greater than the distance between the second part and the axis of rotation of the swing structure 41. Therefore, the swing angle of the swing structure 41 is greater than the rotation angle of the button 11. When the drive body 33 rotates, the elastic connection part 32 connected to it deforms. Since the elastic connection part generates a restoring force, it can eliminate button play to a certain extent and optimize the switch pressing feel.
