Description

Technical Field

[0001] The present invention relates to the field of low-voltage electrics, in particular to a driving member for a switching device and a switching device having the driving member. Background Art

[0002] Currently, most of the existing switching devices directly connect their buttons to the internal swing structures therein to drive the closing and opening of the conductive components inside the switching devices. In this structure, the rotation angle of the button is consistent with the swing angle of the swing structure, which results in the limitation of the overall thickness dimension of the switching device. The switching device requires a relatively large thickness both inside and outside the wall, restricting the appearance effect of the switching device.

[0003] Although there are existing designs that propose to respectively arrange a rocker on both sides of the swing structure, and operate the swing of the swing structure by pressing the two rockers on both sides of the button, so as to realize that the button drives the swing structure to swing at a larger swing angle with a smaller rotation angle, thereby reducing the thickness of the switching device. However, the production and assembly of the related design structures are inconvenient, and the reliability is also poor. Summary of the Invention

[0004] The purpose of the present invention is to provide a driving member that can reduce the rotation angle of the button of the switching device without reducing the swing amplitude of the swing structure, and is easy to produce, assemble, and has high reliability.

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

[0006] The present invention provides a driving member for a switching device. The switching device includes a button and a swing structure. The driving member can be arranged between the button and the swing structure, and can drive the swing structure to swing accordingly under the pressing action of the button to realize the connection or disconnection of the circuit of the switching device. The driving member includes at least two driving bodies, a connecting body, and at least two elastic connecting parts. At least one of the driving bodies is arranged at each end of the connecting body. The elastic connecting parts are connected between the driving bodies and the connecting body. The driving member of the present 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 still another schematic embodiment of the driving member of the present invention, the driving body includes a rotating shaft. Under the drive of the button, the driving body can be supported on the switching device through the rotating shaft and rotate accordingly.

[0008] In another schematic embodiment of the driving member of the present invention, the driving body includes a pressing portion and a driving portion. Under the pressing of the key, the pressing portion can drive the driving body to rotate. The driving portion can drive the swinging structure to swing.

[0009] In yet another schematic embodiment of the driving member of the present invention, the distance between the pressing portion and the rotating shaft is less than the distance between the driving portion and the rotating shaft. Optionally, the pressing portion is located between the rotating shaft and the driving portion. Since the distance between the pressing portion and the rotating shaft is less than the distance between the driving portion and the rotating shaft, when the driving body rotates, the stroke of the pressing portion is less than the stroke of the driving portion, and a larger swinging angle of the swinging structure can be driven with a smaller rotating angle of the key.

[0010] In yet another schematic embodiment of the driving member of the present invention, one of the driving bodies is connected to the connecting body through one or two of the elastic connecting portions.

[0011] In yet another schematic embodiment of the driving member of the present invention, the elastic connecting portion includes an extension arm and at least one elastic arm. One end of the extension arm is connected to the connecting body. Both ends of the elastic arm are respectively connected to the other end of the extension arm and one of the driving bodies.

[0012] In yet another schematic embodiment of the driving member of the present invention, two elastic arms are connected to one extension arm, and multiple driving bodies can be arranged within the limited space of the switching device.

[0013] In yet another schematic embodiment of the driving member of the present invention, the elastic connecting portion further includes a support block, which is formed by extending from the extension arm towards the functional module of the switching device and is used to support the extension arm. When the driving body rotates, the elastic arm connected thereto deforms. Due to the provision of the support block on the extension arm, the deformation of this elastic arm will not interfere with another elastic arm on the extension arm to which it is connected.

[0014] In yet another schematic embodiment of the driving member of the present invention, the elastic arm includes a bent section, which makes the rotation axis of the driving body parallel to the rotation axis of the swinging structure. In addition, setting the bent section can provide more deformation space for the elastic connecting portion.

[0015] In yet another schematic embodiment of the driving member of the present invention, the connecting body is provided with at least one positioning portion.

[0016] In yet another schematic embodiment of the driving member of the present invention, the positioning portion is a positioning groove, a positioning post or a buckle.

[0017] In still another exemplary embodiment of the driving member of the present invention, an opening is provided in the middle of the connecting body. The swinging structure of the switch device can extend out from the opening, thereby reducing the overall thickness of the switch device.

[0018] In still another exemplary embodiment of the driving member of the present invention, the driving member is integrally formed.

[0019] The present invention also provides a switch device, including a key, a functional module, and the driving member according to any one of the above solutions. The driving member can rotate under the drive of the key and drive the swinging structure in the functional module to swing. This switch device has a small overall thickness, is easy to produce and assemble, and has high reliability.

[0020] In still another exemplary embodiment of the switch device of the present invention, the switch device includes a pressing plate, and the driving member is detachably connected to the surface of the pressing plate facing the functional module. By detachably connecting the driving member to the pressing plate, the assembly of the switch device can be facilitated. Description of the Drawings

[0034] For a clearer understanding of the technical features, objectives, and effects of the present invention, the detailed implementation manners of the present invention are now described with reference to the accompanying drawings. In each figure, the same reference numerals denote components having the same or similar structures but the same functions.

[0035] In this document, "schematic" means "serving as an example, instance, or illustration", and any illustration or implementation manner described as "schematic" in this document should not be construed as a more preferred or more advantageous technical solution.

[0036] In this document, "first", "second", etc. do not indicate their importance or order, etc., but are only used to indicate the difference between each other for the convenience of document description.

[0037] To simplify the drawings, only the parts related to the present invention are schematically shown in each figure, and they do not represent the actual structure of the product. In addition, for the sake of simplicity and easy understanding of the drawings, in some figures, for components having the same structure or function, only one of them is schematically shown, or only one of them is labeled.

[0038] Refer to Figure 1 , which shows an exploded structural schematic diagram of a schematic implementation manner of the switch device of the present invention. The switch device includes a key 10, a pressing plate 20, a driving member 30, a function module 40, and a mounting bracket 50. Among them, the number of keys 10 can be set to one, two, three, four, or other numbers. Figure 1 In the case where three keys are provided in , they respectively include key 11, key 12, and key 13. The function module 40 includes a swinging structure, and the swinging structure can drive the circuit of the switch device to be turned on and off. The driving member 30 can drive the swinging structure to swing under the action of the key 10. The driving member 30 includes a connecting body, a driving body, and an elastic connection part connecting the connecting body and the driving body. The driving member 30 is detachably connected to one side of the pressing plate 20 facing the function module 40. In addition, the switch device may not be provided with the pressing plate 20, and the driving member 30 may be detachably connected to the function module 40, or in other ways, which are not limited herein. Specifically, a positioning portion 311 can be provided on the connecting body 31 of the driving member 30, and the positioning portion 311 can be a positioning groove, a positioning post, a buckle, or other ways. This integrally designed driving member is convenient for production and assembly, and can reduce the overall thickness of the switch device having it.

[0039] Refer to Figure 2, which shows a schematic structural diagram of an exemplary embodiment of the driving member of the present invention. The driving member 30 can be used for a three-button switch. The driving member 30 can be integrally formed, and it includes a connecting body 31, four elastic connecting portions 32, and six driving bodies 33. The driving bodies 33 are connected to the connecting body 31 through the elastic connecting portions 32. Specifically, the driving body 33 can be connected to the connecting body through one elastic connecting portion 32 or through two elastic connecting portions 32. Under the driving of the button, the driving body 33 can rotate and drive the swinging structure to swing.

[0040] A positioning portion 311 can be provided on the connecting body 31 for positioning the driving member 30 in the switch device. Specifically, the positioning portion 311 can be a positioning notch. A positioning post is provided on the pressing plate, and the driving member 30 is positioned in the switch device through the cooperation of the positioning notch and the positioning post. An opening 312 is provided in the middle of the connecting body 31 to allow the end of the swinging structure to pass through, thereby reducing the overall thickness of the switch device.

[0041] The driving body 33 includes a rotating shaft 331, a pressing portion 332, and a driving portion 333. Under the driving of the button, the driving body 33 can be supported on the switch device through the rotating shaft 331 and rotate accordingly. The pressing portion 332 can drive the driving body 33 to rotate, so that the driving portion 333 drives the swinging structure 41 to swing. The driving bodies 33 can be arranged on both sides of the connecting body 31 as Figure 2 shown.

[0042] As Figure 2 shown, the pressing portion 332 is located between the rotating shaft 331 and the driving portion 333. When the driving body 33 rotates, the pressing portion 332 and the driving portion 333 have the same rotation angle. However, since the distance between the pressing portion 332 and the rotating shaft 331 is less than the distance between the driving portion 333 and the rotating shaft 331, the stroke of the driving portion 333 is greater than the stroke of the pressing portion 332. The driving body 33 can amplify the stroke when the button rotates and transmit it to the inside of the switch device, thereby reducing the overall thickness of the switch device. In addition, the pressing portion 332 and the driving portion 333 can also be arranged on both sides of the rotating shaft 331.

[0043] Figure 2 Each elastic connecting portion 32 can further include an extension arm 321 and an elastic arm 322. One end of the extension arm 321 is connected to the connecting body 31. Both ends of the elastic arm 322 are respectively connected to the other end of the extension arm 321 and a driving body 33. As Figure 2 shown, when it is necessary to connect two linkage members 33 with one elastic connecting portion 32, two elastic arms 322 can be connected to the end of one extension arm 321.

[0044] Refer to Figure 3 , which shows Figure 2Structural schematic diagram of the middle driving member from another perspective. The elastic connection part 32 further includes a support block 3211. The support block 3211 is formed by extending the extension arm 321 towards the functional module 40 of the switch device and can be used to support the extension arm 321. Since the extension arm 321 is supported on the functional module 40 through the support block 3211, it will not deform due to the rotation of the driving body 33. Therefore, when an elastic arm 322 connected thereto deforms due to the rotation of its corresponding driving body 33, this elastic arm 322 will not interfere with another elastic arm 322 connected to the extension arm 321, so as to maintain the mutual independence between adjacent driving bodies 33. The elastic arm 322 may further include a bending section 3221, and the bending section 3221 can make the rotation axis of the driving body 33 connected thereto parallel to the rotation axis of the swing structure 41 and provide a large space for the deformation of the elastic arm 322.

[0045] In addition to Figure 2 , Figure 3 the driving member 30 shown in, the driving member of the present invention may also adopt other forms, which are not limited herein. For example, only two driving bodies may be symmetrically arranged on both sides of the driving member connection body, and each driving body is connected to the connection body through one or two elastic connection parts; or four driving bodies may be symmetrically arranged on both sides of the driving member connection body, and each driving body is connected to the connection body through one or two elastic connection parts; or eight driving bodies may be symmetrically arranged on both sides of the driving member connection body, and each driving body is connected to the connection body through one or two elastic connection parts.

[0046] Refer to Figure 4 , which shows a cross-sectional view taken along the Figure 1 swing structure below the button 11 of the switch device in and perpendicular to the rotation axis of the swing structure. The driving member 30 is assembled between the button 11 and the swing structure 41. When the button 11 is rotated, the driving body 33 corresponding to the pressed side of the button 11 rotates around the rotation shaft 331 of the driving body 33 towards 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 action on the first part of the pressing part 332 is smaller than the stroke of the swing structure 41 acting on the second part of the driving end 333; the distance between the first part and the rotation axis of the button 11 is greater than the distance between the second part and the rotation axis 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 driving body 33 rotates, the elastic connection part 32 connected thereto deforms. Since the elastic connection part will generate a restoring force, it can, to a certain extent, eliminate the button play and optimize the switch pressing feel.
