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

[0002] Switching devices are commonly used to control the on / off state of circuits, especially when mounted on walls for LED lighting control. However, due to issues with component precision and fit, existing switching devices often experience problems such as incomplete operation after the switch plate is pressed, and the plate cannot be reliably limited. Furthermore, the rotating component cannot simultaneously press down both the oscillating plate and the cover plate. Summary of the Invention

[0003] The purpose of this invention is to overcome the shortcomings of the prior art and provide a switching device that can reliably limit the pressure plate.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A switching device includes a rotatable cover plate and a transmission member. One side of the transmission member engages with the cover plate, and the other side of the transmission member engages with two rotatable rotating members. When the cover plate rotates to one side, the transmission member drives the two rotating members to rotate, causing the rotating members to press against the raised portion of the other side of the cover plate.

[0006] Preferably, the cover plate is provided with a driving component that cooperates with the transmission component. The driving component includes two push rods symmetrically arranged on both sides of the transmission component. One end of each push rod is connected to the rotation center, and the other end of each push rod is provided with multiple protrusions. When the driving component rotates towards one side of the push rod, the multiple protrusions on that side push rod can sequentially push the transmission component, causing the transmission component to rotate and drive the swing plate to contact and separate from the stationary contact.

[0007] Preferably, the two rotating parts each include a pivot part, and a power part and a limiting part respectively disposed on both sides of the pivot part. The limiting part of each transmission part is connected to the power part of the other rotating part by a spring. The power part cooperates with the transmission part, and the limiting part cooperates with the cover plate.

[0008] Preferably, the pivots of the two rotating parts have the same rotation center, and the power part and the limiting part of each rotating part are arranged in the same plane. The pivot part is located on one side of the power part and the limiting part, forming a clearance groove to avoid the pivot part of the other rotating part, and a swing groove to avoid the limiting part of the other rotating part is formed between the power part and the limiting part. The pivot parts of the two rotating parts are respectively inserted into the clearance groove of the other rotating part and rotate, while their respective limiting parts pass through the swing groove and extend between the limiting part and the power part of the other rotating part and are connected to the power part of the other rotating part through a spring.

[0009] Preferably, the pivot portions of the two rotating parts are provided with pivot holes; the middle part of the power part is connected to the pivot portion, the power part is provided with a first boss at one end near the limiting part, and the other end of the power part is bent away from the pivot portion to form a curved part, and a power boss that cooperates with the driving part is provided on the curved part; one end of the limiting part is connected to the pivot portion, and the cover plate is provided with limiting ribs on both sides of its own rotation center that cooperate with the other end of the limiting part, the two limiting ribs are respectively connected to the side of the driving part, and a second boss is provided in the middle of the limiting part. Two springs correspond one-to-one with the two rotating parts, one end of the two springs is respectively sleeved on the first boss of the corresponding rotating part, and the other end of the two springs is respectively sleeved on the second boss of the other rotating part.

[0010] Preferably, the rotating component and the cover plate are rotatably mounted on the pressure plate component, and the axes of rotation of the transmission component, the rotating component and the cover plate are arranged in parallel; the pressure plate component is connected to the mounting frame, and a buckle for connecting the mounting frame is provided on the pressure plate component.

[0011] Preferably, the two push rods are each provided with two protrusions, and the two protrusions on each push rod are spaced apart.

[0012] Preferably, the side of the protrusion on the push rod that is furthest from the center of rotation is flush with the end face of the push rod that is furthest from the center of rotation.

[0013] Preferably, the cross-section of the protrusion is semi-circular, and the side of the protrusion near the transmission component has an arc-shaped structure.

[0014] Preferably, it further includes a swing plate that cooperates with the transmission component. Two stationary contacts are arranged opposite each other on both sides of the swing plate. When the transmission component rotates, it drives the swing plate to contact one of the stationary contacts. The driving component has a U-shaped structure. The ends of the two push rods away from the protrusion are connected by a connecting rod, which is connected to the cover plate. The transmission component is located inside the driving component. The transmission component includes a transmission shaft and a long transmission part and a short transmission part, one end of which is connected to the transmission shaft. The two sides of the other end of the long transmission part cooperate with the two push rods respectively, and the middle is provided with a swing groove for driving the swing plate to rotate. The two sides of the other end of the short transmission part cooperate with the limiting mechanism respectively.

[0015] The switching device invented in this invention uses a rotating component instead of a transmission component to hold the raised end of the cover plate in place, ensuring that it can rotate to the correct position. Furthermore, multiple protrusions on the driving component can be divided into multiple segments to push the transmission component separately, making it easier for the push rod to drive the transmission component to rotate to the correct position.

[0030] The switching device created by the present invention includes a rotatable transmission member 100. One side of the transmission member 100 is engaged with a cover plate 510, and the other side of the transmission member 100 is engaged with two rotatable rotating members 300 respectively. When the cover plate 510 rotates to one side, the transmission member 100 drives the two rotating members 300 to rotate respectively, so that the rotating members 300 press against the raised part on the other side of the cover plate 510.

[0031] The switching device created by the present invention uses a rotating component 300 to replace the transmission component to hold the raised end of the cover plate 510, ensuring that 510 can rotate into place.

[0032] The following is in conjunction with the appendix Figures 1 to 14The given embodiments further illustrate specific implementations of the switching device created by the present invention. The switching device created by the present invention is not limited to the descriptions of the following embodiments.

[0033] like Figure 1-3 As shown, the switching device created by the present invention includes a mounting bracket 500, and an operating mechanism and an actuator respectively disposed on both sides of the mounting bracket 500. The operating mechanism controls the actuator to turn on and off the power supply.

[0034] The operating mechanism includes a drive component and a cover plate 510 connected to the drive component. The cover plate 510 is rotatably mounted on the pressure plate component 520, and the pressure plate component 520 is then fixedly connected to the mounting bracket 500. The cover plate 510 drives the drive component to rotate, controlling the actuator to turn on and off the power.

[0035] Specifically, the driving component has a U-shaped structure and includes two push rods 210 arranged opposite to each other on both sides of the transmission component 100, and a connecting rod 230 connecting the two push rods 210 at the ends away from the protrusion 220. The connecting rod 230 is connected to the cover plate 510, and the transmission component 100 is located inside the driving component.

[0036] Two connectors 511, whose connecting lines are perpendicular to the connecting lines of the two push rods 210, are arranged opposite each other on both sides of the driving member. One end of each connector 511 is connected to the cover plate 510, and the other end of each connector 511 is provided with a pivot hole 512. The pivot holes 512 of the two connectors 511 can be respectively fitted onto the pressure plate shaft 521 of the pressure plate member 520, so that the cover plate 510 can drive the two push rods 210 to rotate around the pressure plate shaft 521. A pressure plate hole 522 for avoiding the driving member is provided in the middle of the pressure plate member 520. The two push rods 210 of the driving member first pass through the pressure plate hole 522, and then the pivot hole 512 on the cover plate 510 is fitted onto the pressure plate shaft 521. When the cover plate 510 rotates to the point where one end is limited by the pressure plate member 520, the other end of the cover plate 510 tilts up. Pressing down on the tilted part of the cover plate 510 can drive the cover plate 510 to drive the driving member to rotate.

[0037] It is understood that the driving component can also be separately set from the cover plate 510. The driving component can be rotatably mounted on the pressure plate 520 or the mounting bracket 500. The cover plate 510 can push or drive the driving component to rotate in other ways, or it can drive the driving component to rotate through other parts. All of these are within the protection scope of this invention.

[0038] like Figure 2-3 As shown, in this embodiment, two protrusions 220 are provided on the inner side of the two push rods 210 respectively, and the two protrusions 220 on each push rod 210 are spaced apart. The two protrusions 220 on each push rod 210 can push the transmission member 100 sequentially from the same side.

[0039] Figure 4and Figure 6 The positions of the drive member before and after rotating to one side of the push rod 210 are shown respectively. The two push rods 210 are the left push rod 211 and the right push rod 212. One end of the left push rod 211 and the right push rod 212 are connected by the connecting rod 230. The other end of the left push rod 211 and the right push rod 212 are respectively provided with an upper protrusion 221 and a lower protrusion 222 that are spaced apart. The upper protrusion 221 is located between the lower protrusion 222 and the connecting rod 230.

[0040] See Figure 4 The right end of the cover plate 510 is raised and pressed down, causing the push rod 210 of the driving component to rotate clockwise. When the driving component rotates, it drives the lower protrusion 222 of the right push rod 212 to push the transmission component 100 towards... Figure 6 Position rotated.

[0041] See Figure 6 Because the rotation centers and rotation distances of the right push rod 212 and the transmission component 100 are different, the lower protrusion 222 will separate from the transmission component 100 after the right push rod 212 rotates a certain angle. To prevent the transmission component 100 from being unable to continue rotating after the lower protrusion 222 separates from the transmission component 100, the upper protrusion 221 of the right push rod 212 can contact the transmission component 100 before the lower protrusion 222 separates from the transmission component 100. The upper protrusion 221 of the right push rod 212 pushes the transmission component 100 to continue rotating, ensuring that the transmission component 100 can rotate to... Figure 6 Location. By Figure 6 Towards Figure 4 When the position rotates, the direction is reversed, and the left push rod 211 replaces the right push rod 212 to drive the transmission component 100, which is the same principle.

[0042] It is understood that more protrusions 220 can be provided on each push rod 210, such as three or more. Some of the protrusions 220 can also be arranged adjacently, all of which fall within the protection scope of this invention.

[0043] Preferably, the side of the push rod 210 with the furthest point 220 from the rotation center, i.e., the side of the lower protrusion 222 away from the rotation center, is opposite to the end face 2100 of the push rod 210 at the end away from the rotation center. Figure 3-4 The lower convex point 222 is flush with the upper convex point 221, ensuring that the lower convex point 222 is positioned at the furthest point from the rotation center. This makes the lower convex point 222 and the upper convex point 221 work together more reliably, allowing the transmission component 100 to be pushed and disengaged from the transmission component 100 at a more reasonable position.

[0044] Preferably, the cross-section of the protrusion 220 is semi-circular, and the side of the protrusion 220 near the transmission component 100 is arc-shaped. The arc-shaped structure can reduce the friction between the protrusion 220 and the transmission component 100, which can not only prevent jamming, but also reduce wear and improve service life.

[0045] like Figure 4-8 As shown, the operating mechanism also includes a limiting mechanism that cooperates with the cover plate 510. After the cover plate 510 rotates, the limiting mechanism can hold the raised end of the cover plate 510 to prevent the cover plate 510 from rotating into place and then malfunctioning.

[0046] See Figure 8 The transmission component 100 includes a long transmission part 110 and a short transmission part 120 arranged coaxially. The long transmission part 110 cooperates with the driving component, and the short transmission part 120 is disposed on one side of the long transmission part 110 and cooperates with the limiting mechanism. When the driving component drives the driving component to rotate through the long transmission part 110, the driving component drives the limiting mechanism to rotate through the short driving part 120.

[0047] like Figure 5 , 7 As shown, the limiting mechanism of this embodiment includes two rotatable rotating members 300. The two rotating members 300 are disposed on both sides of the transmission member 100 in the rotation direction. One end of each of the two rotating members 300 engages with the sides of the short transmission part 120, and the other end of each of the two rotating members 300 engages with the sides of the cover plate 510. The ends of the two rotating members 300 that engage with the cover plate 510 are connected to the other rotating member 300 via springs 3000. When the cover plate 510 pushes the drive member to rotate, it compresses the springs 3000, causing the drive member to drive the swing plate 410 to rotate, which in turn drives the two rotating members 300 to rotate together. When the drive member rotates to its position, it releases the cover plate 510, and the springs 3000 push the rotating members 300 to press against the raised end of the cover plate 510. The rotating members 300 replace the transmission member in pressing against the cover plate 510, ensuring that 510 can rotate to its position.

[0048] See Figure 9 The two rotating parts 300 each include a pivot part 310, and a power part 320 and a limiting part 330 respectively disposed on both sides of the pivot part 310. The pivot parts 310 of the two rotating parts 300 have the same rotation center, but the rotation directions of the two pivot parts 310 are opposite. The limiting part 330 of each rotating part 300 is connected to the power part 320 of the other rotating part 300 through a spring 3000. The spring 3000 pushes the limiting part 330 to press against the raised end of the cover plate 510 to prevent the cover plate 510 from rotating on its own. During operation, if the raised end is pressed, the spring 3000 can be compressed to ensure that the cover plate 510 rotates flexibly.

[0049] See Figure 9-10The power part 320 and the limiting part 330 of the rotating member 300 are arranged in the same plane, and the pivot part 310 is located on one side of the power part 320 and the limiting part 330, forming a clearance groove 311 to avoid the pivot part 310 of another rotating member 300, and a second swing groove 312 to avoid the limiting part 330 of another rotating member 300 is formed between the power part 320 and the limiting part 330.

[0050] See Figure 11-12 The pivoting portions 310 of the two rotating members 300 are respectively inserted into the clearance grooves 311 of the other rotating member 300 for rotation. At the same time, their respective limiting portions 330 pass through the second swing groove 312 and extend between the limiting portion 330 and the power portion 320 of the other rotating member 300, so that the limiting portion 330 can be connected to the power portion 320 of the other rotating member 300 through the spring 3000. Figure 12 Only the left spring 3000 is shown in the image; the right spring 3000 is hidden. It is understood that the limiting mechanism can also employ other structures, such as two springs respectively connected to the cover plate 510, all of which fall within the scope of protection of this invention.

[0051] See Figure 13 The pressure plate member 520 has a pressure plate hole 522 for avoiding the driving member and also for avoiding the two rotating members 300. A pivot shaft 523 for pivotally mounting the two rotating members 300 is provided in the pressure plate hole 522.

[0052] See Figure 9 The pivot part 310 is provided with a pivot hole 5230 that rotates on the pivot shaft 523 of the pressure plate 520;

[0053] The middle part of the power unit 320 is connected to the pivot part 310. The power unit 320 has a first boss 321 at one end near the limiting part 330. The other end of the power unit 320 is bent away from the pivot part 310 to form a curved part 322. A power boss 323 that cooperates with the driving member is provided on the curved part 322.

[0054] One end of the limiting part 330 is connected to the pivot part 310. The cover plate 510 is provided with limiting ribs 331 on both sides of its own rotation center, which cooperate with the other end of the limiting part 330. The two limiting ribs 331 are respectively connected to the side of the driving member. A second boss 332 is provided in the middle of the limiting part 330.

[0055] Two springs 3000 correspond one-to-one with two rotating parts 300. One end of each spring 3000 is fitted onto the first boss 321 of the corresponding rotating part 300, and the other end of each spring 3000 is fitted onto the second boss 332 of the other rotating part 300.

[0056] The above Figure 4and Figure 6 The positions of the drive member before and after rotating to one side of the push rod 210 are shown respectively. Figure 5 and Figure 7 Corresponding to Figure 4 and Figure 6 The position of the limit mechanism in the state.

[0057] See Figure 5 The right end of the cover plate 510 is raised, and the right side of the short transmission part 120 of the transmission member 100 abuts against the power boss 323 of the right rotating member 300, causing the right rotating member 300 to be subjected to a force that rotates counterclockwise around the pivot hole 5230. The first boss 321 of the right rotating member 300 abuts against the second boss 332 of the left rotating member 300 in a counterclockwise direction through the spring 3000, thereby causing the limiting part 330 of the left rotating member 300 to abut against the limiting rib 331 on the right side of the cover plate 510 at an angle upward, preventing the cover plate 510 from being raised. As the right end of 10 descends, the second protrusion 332 of the right rotating member 300 pushes against the first protrusion 321 of the left rotating member 300 in a counterclockwise direction via the spring 3000. This also causes the left rotating member 300 to be subjected to a counterclockwise rotational force, thereby causing the limiting part 330 of the left rotating member 300 to press against the limiting rib 331 on the right side of the cover plate 510. At this time, the limiting part 330 of the right rotating member 300 has a gap with the limiting rib 331 on the left side of the cover plate because the rotating member rotates counterclockwise.

[0058] Depend on Figure 5 Towards Figure 7 During the rotation, the left side of the short transmission part 120 of the transmission member 100 pushes the power boss 323 of the left rotating member 300 to rotate, so that the left rotating member 300 is subjected to a force that rotates clockwise around the pivot hole 5230. When rotating, the first boss 321 of the left rotating member 300 pushes the second boss 332 of the right rotating member 300 to rotate together in the clockwise direction through the spring 3000, so that the limiting part 330 of the right rotating member 300 presses obliquely upward against the left side of the cover plate 510. The limiting rib 331 prevents the left side of the cover plate 510 from falling down. At the same time, the second boss 332 of the left rotating member 300 presses against the first boss 321 of the right rotating member 300 in a clockwise direction through the spring 3000. This also causes the right rotating member 300 to be subjected to a clockwise rotational force, so that the limiting part 330 of the right rotating member 300 presses against the limiting rib 331 on the left side of the cover plate 510. At this time, there is a gap between the limiting part 330 of the left rotating member 300 and the limiting rib 331 on the right side of the cover plate.

[0059] like Figure 4-8The structure of the transmission component 100 in this embodiment is shown. The transmission component 100 includes a long transmission part 110, a short transmission part 120, and a transmission shaft 130. The transmission shaft 130 is rotatably mounted inside the housing 400 of the actuator. The length of the short transmission part 120 is less than that of the long transmission part 110. One end of the long transmission part 110 and the short transmission part 120 are respectively connected to the transmission shaft 130. The other ends of the long transmission part 110 and the short transmission part 120 can rotate around the transmission shaft 130. The two sides of the other end of the short transmission part 120 are respectively engaged with a limiting mechanism. The two sides of the other end of the long transmission part 110 are respectively engaged with a driving component, and a first swing groove 140 is provided in the middle, which is sleeved on the end of the swing plate 410. When the long transmission part 110 rotates around the transmission shaft 130, it drives the swing plate 410 to rotate and contact and separate from the stationary contact 420 through the first swing groove 140. This embodiment is a double-control switch, including two stationary contacts 420, which are respectively disposed on both sides of the swing plate 410.

[0060] like Figure 13-14 The structure of the pressure plate 520 in this embodiment is shown. The operating mechanism and the limiting mechanism in this embodiment are respectively installed on the pressure plate 520 and are installed together as a whole on the mounting frame 500. The pressure plate 520 is provided with an insertion plate 524 protruding towards the mounting frame 500, and the insertion plate 524 is provided with a buckle 525. The mounting frame 500 is provided with a through hole 526 that cooperates with the buckle 525. The insertion plate 524 extends through the through hole 526 to the other side of the mounting frame 500, so that the buckle 525 on the insertion plate 524 is limited and fixed with the side of the mounting frame 500 away from the pressure plate 520, which has the feature of convenient assembly.

[0061] Specifically, it includes two pairs of insertion plates 524. The two insertion plates 524 of each pair are respectively arranged on both sides along the width direction of the pressure plate 520 and are respectively connected to the long sides of the opposite sides of the pressure plate 520. The distance between the two insertion plates 524 of each pair is greater than the width of the housing 400 of the actuator.

[0062] Pressure plate shafts 521 are provided on the opposite short sides of the pressure plate component 520, and the cover plate 510 is sleeved on the pressure plate shafts 521 and rotates.

[0063] The pressure plate 520 has a pressure plate hole 522 in the middle for avoiding the driving component. The two opposing inner walls of the pressure plate hole 522 are connected by a pivot shaft 523. The two rotating parts 300 of the limiting mechanism are mounted on the pivot shaft 523 and rotate.

[0064] The transmission shaft 130 of the transmission component 100, the pressure plate shaft 521, and the pivot shaft 523 serve as the axes of rotation for the transmission component 100, the cover plate 510, and the rotating component 300, respectively. The three are arranged in parallel to each other, and the axis of rotation of the cover plate 510 is the axis of rotation of the driving component.

[0065] The above description, in conjunction with specific preferred embodiments, provides a further detailed explanation of the present invention. It should not be construed that the specific implementation of the present invention is limited to these descriptions. For those skilled in the art, various simple deductions or substitutions can be made without departing from the inventive concept, and all such modifications and substitutions should be considered within the scope of protection of the present invention.
