[0002] With the continuous development of smart home devices, electric curtains have gradually come into people's view and are expected by more and more people. The electric curtain can drive the opening or closing of the curtain through the power provided by the motor.
[0003] The switching device of the traditional electric curtain can be turned on during user operation (for example, when the switching device is pressed) under the action of the internal mechanism, and after the user releases the operation (for example, the user no longer presses the switching device), the switch resets and cuts off the circuit connection. Thus, the user can control the working time of the motor through the switch, and further control the position where the curtain moves. Summary of the Utility Model
[0004] In a first aspect of the present disclosure, a switching device for an electrical device is provided. The switching device includes: a housing; at least one stationary contact disposed in the housing; a button movably coupled to the housing and adapted to move between at least one on position and an off position; and a power connection assembly coupled to the button and including: a terminal block coupled to the housing and connected to the circuit of the electrical device; a contact member movably coupled to the terminal block and including a moving contact adapted to be pushed by the button during the movement of the button from the off position to at least one on position and to contact the stationary contact; and an elastic member disposed between the terminal block and the contact member and adapted to provide an elastic force to the contact member to keep the moving contact spaced apart from the stationary contact by a predetermined distance when the button is in the off position.
[0005] In some embodiments, the terminal block includes: a wiring member adapted to be connected to the circuit; and a connecting member including: a connecting portion coupled to the wiring member; a first mounting portion arranged to extend from a first end of the connecting portion in a first direction away from the first end of the connecting portion to be adapted to be coupled to the contact member; and a second mounting portion arranged to extend from a second end of the connecting portion opposite to the first end in the first direction to be adapted to be coupled to the elastic member.
[0006] In some embodiments, the contact member includes a contact wall disposed on a side of the first mounting portion facing away from the second mounting portion and adapted to contact the first mounting portion to allow the contact member to swing within a predetermined angle with the contact wall as a fulcrum.
[0007] In some embodiments, the contact member further includes a mounting hole, the contact wall is disposed on a side of the mounting hole away from the second mounting portion, and the second mounting portion passes through the mounting hole.
[0008] In some embodiments, the contact member further includes a hook disposed between the first mounting portion and the second mounting portion, and the elastic member includes a tension spring, and two ends of the tension spring are respectively coupled to the second mounting portion and the hook.
[0009] In some embodiments, the connecting member further includes a mounting groove disposed on a side facing away from the contact member and adapted to fix the wiring member.
[0010] In some embodiments, the button includes: an outer cover coupled to the housing and adapted to rotate within a predetermined range about a rotation axis; and a driving member coupled to the housing and including a part coupled to the contact member and partially surrounding both sides of the contact member to abut against the contact member and drive the contact member to swing during rotation of the outer cover.
[0011] In some embodiments, the housing includes a pair of fixed shafts respectively disposed on both sides of the housing and aligned on an axis; and the outer cover includes a pair of card slots respectively coupled to the pair of fixed shafts and partially surrounding the fixed shafts to enable the outer cover to rotate about an axis of the pair of fixed shafts.
[0012] In some embodiments, the outer cover includes a receiving groove adapted to partially receive the driving member and drive the driving member to rotate with the outer cover.
[0013] When the user presses the button and moves the button from the off position to the on position, the driving member of the button pushes against the contact member, causing the contact member to swing relative to the connecting member with the contact wall as an axis, so that the moving contact disposed on the contact member can contact the corresponding stationary contact in the housing, thereby turning on the switch device. When the user removes the operation, the contact member resets under the action of the elastic member, so that the moving contact and the stationary contact are spaced apart by a predetermined distance again, that is, the switch device returns to the off state again. In this way, by driving the contact member to reverse through the driving member, the contact between the moving contact and the stationary contact is controlled, and the structure is simple and highly reliable. Thereby, the stability of the switch device during long-term use can be improved.
[0014] In a second aspect of the present disclosure, an electrical device is provided. The electrical device includes: the switch device provided according to the first aspect of the present disclosure.

[0024] Embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. Although certain embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure can be implemented in various forms and should not be construed as limited to the embodiments set forth herein. On the contrary, these embodiments are provided to more thoroughly and completely understand the present disclosure. It should be understood that the drawings and embodiments of the present disclosure are only for exemplary purposes and are not used to limit the scope of protection of the present disclosure.
[0025] It should be noted that the titles of any section / subsection provided herein are not restrictive. Various embodiments are described throughout this document, and any type of embodiment can be included under any section / subsection. In addition, the embodiments described in any section / subsection can be combined with any other embodiments described in the same section / subsection and / or different section / subsections in any manner.
[0026] In the description of the embodiments of the present disclosure, the term "including" and its like terms should be understood as open inclusion, that is, "including but not limited to". The term "based on" should be understood as "at least partially based on". The term "an embodiment" or "the embodiment" should be understood as "at least one embodiment". The term "some embodiments" should be understood as "at least some embodiments". There may also be other explicit and implicit definitions hereinafter. The terms "first", "second", etc. may refer to different or the same objects. There may also be other explicit and implicit definitions hereinafter.
[0027] As briefly mentioned above, the user can control the forward or reverse rotation of the electrode through the switch device, and then control the opening and closing of the electric curtain. Figure 1 A simple schematic diagram of a traditional switch device is shown. As Figure 1 shown, the traditional switch device includes a pair of static contacts 101, a V-shaped silver bridge 102 (also known as a conductive connection member) arranged between the pair of static contacts 101, and a base 103 coupled to the silver bridge 102. The base 103 and the static contacts 101 are respectively coupled to the power supply side and the power consumption side of the switch. The pair of static contacts 101 respectively correspond to different working modes of the motor (such as forward rotation or reverse rotation). When the user presses the switch to one side, the panel of the switch drives the silver bridge 102 to deflect towards the static contact 101 on one side, and the moving contact arranged at the end of the silver bridge 102 contacts the corresponding static contact 101, and then the base 103 is electrically connected to the corresponding static contact 101. In this way, the switch device conducts a certain working circuit of the motor, and then controls the forward rotation (or reverse rotation) of the motor.
[0028] However, in such a structure, the coupling method between the silver bridge 102 and the base 103 is unstable. During the movement of the silver bridge 102, the coupling point between the silver bridge 102 and the base 103 is likely to change, thus affecting the stability of the circuit. In addition, after the switch device is used for a long time, the silver bridge 102 and the base 103 are prone to problems such as misalignment and poor contact, thereby affecting the normal use of the switch device.
[0029] To solve or at least partially solve the above problems or other potential problems existing in the conventional technologies, embodiments of the present disclosure provide a switching device for an electrical device and an electrical device. According to various embodiments of the present disclosure, when a user presses a button and moves the button from an off position to a conductive position, a driving member of the button pushes against a contact member, causing the contact member to swing relative to a connecting member with a contact wall as an axis, so that a moving contact arranged on the contact member can contact a corresponding static contact in a housing, thereby turning on the switching device. When the user removes the operation, the contact member resets under the action of an elastic member, so that the moving contact and the static contact are spaced apart by a predetermined distance again, that is, the switching device returns to the off state again. In this way, by pushing the contact member to reverse with the driving member, the contact between the moving contact and the static contact is controlled, and the structure is simple and highly reliable. Thus, the stability of the switching device during long-term use can be improved.
[0030] Figure 2 FIG. shows a simplified schematic diagram of a switching device according to an embodiment of the present disclosure. Figure 3 FIG. shows an exploded view of a switching device according to an embodiment of the present disclosure. As Figure 2 and Figure 3 shown, the switching device generally includes a housing 1, at least one static contact 11 arranged in the housing 1, a button 2 movably coupled to the housing 1, and a power connection assembly 3 arranged in the housing 1. The static contact 11 is electrically connected to the power consumption side (or power supply side) of the switching device. The power connection assembly 3 is electrically connected to the power supply side (or power consumption side) of the switching device. The button 2 is adapted to move from an off position to a conductive position under the operation of a user. During this period, the button 2 drives the power connection assembly 3 to contact and electrically connect with the static contact 11, thereby turning on the switching device.
[0031] Figure 4 FIG. shows an internal structure schematic diagram of a switching device according to an embodiment of the present disclosure. As Figure 4 shown, in some embodiments, the button 2 includes an outer cover 21 and a driving member 22 coupled to the outer cover 21. The housing 1 includes a pair of fixed shafts 12, and the pair of fixed shafts 12 are respectively arranged on opposite sides of the housing 1 and are aligned on the axis. A pair of card slots 24 are formed on the outer cover 21, and the pair of fixed shafts 12 are respectively inserted into the corresponding card slots 24 to couple the button 2 to the housing 1, and the outer cover 21 can rotate around the axis of the fixed shaft 12 within a predetermined angle range. For example, the outer cover 21 can rotate around the fixed shaft 12 in a first rotation direction (for example, clockwise) by 1-5° to rotate from the off position to a first conductive position. The outer shell can also rotate around the axis of the fixed shaft 12 in a second rotation direction by 1-5° to rotate from the off position to a second conductive position.
[0032] In some embodiments, the driving member 22 can be coupled to the outer cover 21 and move synchronously with the movement of the outer cover 21. The outer cover 21 includes a receiving groove 23, and the receiving groove 23 partially houses the driving member 22 therein. The housing is fixed in the receiving groove 23 by a tight fit between the inner wall of the receiving groove 23 and the outer sidewall of the driving member 22. In some embodiments, the bottom of the receiving groove 23 includes a positioning protrusion, and the positioning protrusion abuts against one side of the driving member 22 facing the outer cover 21, thereby ensuring a stable fit between the outer cover 21 and the driving member 22. In some embodiments, the driving member 22 and the housing 1 can also be rotatably coupled to the housing 1 in a manner similar to the cooperation of the fixed shaft 12 and the card slot 24, which will not be elaborated herein in the present disclosure.
[0033] In some embodiments, the rotation axis of the button 2 can be parallel to the plane where the button 2 is located. In some other embodiments, the rotation axis of the button 2 can also have a predetermined non-zero angle with respect to the plane where the button 2 is located (for example, the rotation axis of the button 2 is perpendicular to the plane where the button 2 is located).
[0034] In some embodiments, the button 2 can also move relative to the housing 1 in other suitable ways. For example, the button 2 can slide relative to the housing 1 in a linear direction or at least a partial curved direction.
[0035] In some embodiments, the driving member 22 further includes a driving groove 221. The driving groove 221 partially surrounds both sides of the contact member 5, and the sidewalls on both sides of the driving groove 221 respectively abut against the opposite sides of the driving member 22. When the user operates the switch device and moves the button 2 from the off position to the on position, the sidewall of the driving groove 221 pushes against the contact member 5 and moves the contact member 5. Further, the moving contact 53 of the contact member 5 contacts the static contact 11, thereby realizing the conduction of the switch device.
[0036] In some embodiments, the button 2 of the switch device can only move from the off position to one on position. In this case, one static contact 11 can be arranged in the housing 1. In some other embodiments, the button 2 of the switch device can move from the off position to two or more on positions. Taking two on positions as an example. In this case, two static contacts 11 can be arranged in the housing 1 and the power connection assembly 3 is arranged between the two static contacts 11. When the button 2 moves to one of the on positions, the button 2 can make the power connection assembly 3 contact the corresponding static contact 11. Various embodiments of the present disclosure will be mainly described in the form that the switch device includes two static contacts 11 and two power connection assemblies 3, but it should be understood that the switch device containing any other appropriate number (for example, one) of power connection assemblies 3 and static contacts 11 is similar.
[0037] The power connection assembly 3 is arranged between a pair of static contacts 11, and includes a terminal 4, a contact member 5 coupled to and electrically connected to the terminal 4, and an elastic member 6 arranged between the contact terminals. The terminal 4 includes a wiring member 41 and a connecting member 42. The wiring member 41 is coupled to the housing 1 and electrically connected to the power supply side (or power consumption side) of the switching device.
[0038] Figure 5 and Figure 6 respectively show schematic diagrams of the internal structure of the switching device according to the present disclosure from different perspectives. As Figure 5 and Figure 6 shown, the connecting member 42 includes a connecting portion 421 coupled to the wiring member 41, a first mounting portion 422 disposed at the first end of the extending direction of the connecting portion 421, and a second mounting portion 423 disposed at the second end of the extending direction of the connecting portion 421. The first mounting portion 422 and the second mounting portion 423 are respectively arranged to extend in a first direction away from the connecting portion 421, so that the connecting member 42 is generally C-shaped. The contact member 5 is movably coupled to the first mounting portion 422, and a moving contact 53 is arranged at one end of the contact member 5 away from the first mounting portion 422. If the button 2 moves from the off position to the on position under the user's operation, during which the driving member 22 pushes against the contact member 5 to swing within a predetermined range, and makes the moving contact 53 of the contact member 5 contact the static contact 11. Thus, the switching device is turned on. The elastic member 6 is arranged between the second mounting portion 423 and the contact member 5 and is adapted to provide an elastic force to keep the contact member 5 spaced apart from the static contact 11 by a predetermined distance during the period when the button 2 is in the off position, so as to ensure that the switching device can be stably turned off.
[0039] Figure 7 shows a schematic diagram of the power connection assembly 3 according to an embodiment of the present disclosure. As Figure 7 shown, in some embodiments, the connecting member 42 further includes a mounting groove 424, the mounting groove 424 is arranged on the side of the connecting portion 421 facing away from the contact member 5, and a part of the wiring member 41 is clamped in the mounting groove 424 and coupled to the connecting member 42.
[0040] In some embodiments, the contact member 5 includes a mounting hole 51, and the mounting hole 51 is sleeved on the first mounting portion 422. Further, the contact member 5 further includes a contact wall, the contact wall is arranged on the inner wall of the mounting hole 51 away from the second mounting portion 423, and the contact wall is adapted to contact the first mounting portion 422, thereby allowing the contact member 5 to swing within a predetermined angular range with the contact wall as a fulcrum. A certain gap is left between the mounting hole 51 and the first mounting portion 422, so that the contact member 5 can swing relative to the connecting member 42 within a predetermined angle.
[0041] In some embodiments, the contact member 5 further includes a hook 52 disposed between the first mounting portion 422 and the second mounting portion 423. One end of the elastic member 6 is coupled to the hook 52 and the other end is coupled to the second mounting portion 423. When the driving member 22 pushes against the contact member 5 to swing, the elastic member 6 is stretched, thereby causing the contact member 5 to be in an unstable position. Once the user's operation touches, due to the pulling force of the elastic member 6, the contact member 5 is reset (i.e., a predetermined distance is separated between the moving contact 53 of the contact member 5 and the static contact 11). In some embodiments, the contact member 5 may be a tension spring. In some other embodiments, the contact member 5 may also be other materials having an elastic force.
[0042] In some embodiments, the switch device can be used as a control switch for an electric curtain. For example, a pair of static contacts 11 in the switch device can be used to control the forward or reverse rotation of the electric curtain motor respectively. In some other embodiments, the switch device with one static contact 11 built therein can also be a doorbell switch or an access control switch, etc. The above is only an exemplary illustration of the application of the switch device. In fact, the switch device can also be used in any other suitable fields, and the present disclosure does not make any restrictions in this regard.
[0043] The various implementations of the present disclosure have been described above. The above description is exemplary and not exhaustive, and is not limited to the disclosed implementations. Many modifications and variations are obvious to those of ordinary skill in the art in the technical field without departing from the scope and spirit of the described implementations. The selection of the terms used herein is intended to best explain the principles of the implementations, practical applications, or improvements to the technology in the market, or to enable other ordinary skill in the art in the technical field to understand the various implementation manners disclosed herein.
