In order to make the objects, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application.

The universal change-over switch is a multi-loop control electric appliance formed by overlapping a plurality of groups of contact assemblies with the same structure, and consists of a contact system, a rotating shaft, a handle and other parts. When the universal change-over switch is used, the rotating shaft and the cam are driven to rotate through the handle, the cam is matched with the sliding block in the rotating process, and the driving contact is switched on or off. Because the shapes of the cams are different, when the handle is positioned at different positions, the different positions of the cams are matched with different sliding blocks, so that part of the contacts are switched on, and the other part of the contacts are switched off, thereby achieving the purpose of switching circuits.

During the process that the cam rotates and the contact is pushed to be contacted or disconnected through the sliding block, the inventor finds that: the part of the sliding block contacting the cam is easy to rub by the cam to generate plastic particles, so that the sliding block and the cam are blocked, and the rotating fit of the cam and the sliding block is not facilitated. Therefore, the inventor provides a universal change-over switch through intensive research to solve the problem of the jamming of the sliding block and the cam.

The embodiment of the present application provides a universal switch 1, and fig. 1 is a schematic structural diagram of the universal switch 1 in some embodiments of the present application. As shown in fig. 1, the universal switch 1 includes a slider 11 and a cam 12. Fig. 2 is a schematic structural diagram of the slider 11 according to some embodiments of the present disclosure. As shown in fig. 2, the slider 11 includes: a slider body 111 and a rotating assembly 112. The slider body 111 has an installation portion 1111, and the installation portion 1111 has an accommodation groove. The rotating assembly 112 includes a connecting member 1121 and a rotating member 1122 connected to each other, the connecting member 1121 is connected to the mounting portion 1111 so that the rotating member 1122 is located in the receiving slot, and the rotating member 1122 is configured to be rotationally engaged with the cam 12 when the universal switch 1 is operated.

The slider body 111 is a member for mounting the rotating assembly 112. The slider body 111 mounts the rotation member 112 through the mounting portion 1111 such that a portion of the rotation member 112 is positioned in the receiving groove. The mounting portion 1111 may be located at an end of the slider body 111, and at least a portion of the notch of the receiving groove may face the outside of the slider body 111, so that the rotating member 112 can be rotatably engaged with the cam 12 after being mounted to the mounting portion 1111.

The attachment 1121 is a member for connecting to the mounting portion 1111. The rotor 1122 is a member for rotationally engaging with the cam 12. After the rotating element 1122 and the connecting element 1121 are connected to the mounting portion 1111, the rotating element 1122 can drive the connecting element 1121 to rotate together, or the rotating element 1122 can rotate around the connecting element 1121. The rotational member 1122 may be provided in a cylindrical configuration for rotational engagement with the cam 12 or about the connection member 1121. The connecting member 1121 can also be configured in a cylindrical configuration to facilitate rotation with the rotating member 1122.

Depending on the rotation modes of the rotating elements 1122 and the connecting elements 1121, the connecting elements 1121 and the mounting portions 1111, and the rotating elements 1122 and the connecting elements 1121 may be connected in various ways. In one possible connection, the connecting element 1121 is fixedly connected to the mounting portion 1111, and the rotating element 1122 is rotatably connected to the connecting element 1121, so that when the rotating element 1122 is engaged with the cam 12, the cam 12 applies a force to the rotating element 1122, and the rotating element 1122 rotates around the connecting element 1121 under the action of the force applied by the cam 12 to achieve the rotating engagement with the cam 12. In another possible connection, the connection member 1121 is rotatably connected to the mounting portion 1111, and the rotation member 1122 is fixedly connected to the connection member 1121, so that the rotation member 1122 rotates together with the connection member 1121 under the action of force during the engagement of the rotation member 1122 with the cam 12, thereby achieving the rotation engagement with the cam 12.

When the rotary member 1122 is rotationally engaged with the cam 12, the rotary member 1122 may be rotated in a different direction simultaneously with the cam 12 based on the friction of the cam 12, for example, when the cam 12 is rotated in the clockwise direction, the rotary member 1122 may be rotated in the counterclockwise direction, or when the cam 12 is rotated in the counterclockwise direction, the rotary member 1122 may be rotated in the clockwise direction. When the friction force of the cam 12 on the rotating element 1122 can make the rotating element 1122 rotate, the sliding friction between the rotating element 1122 and the cam 12 is changed into the rotating friction, so the friction force between the rotating element 1122 and the cam 12 is relatively small, the possibility of generating plastic particles due to the friction of the rotating element 1122 by the cam 12 is low, and the rotating element 1122 is less likely to be jammed with the cam 12.

It should be noted that, the portion of the rotating element 1122 rotatably engaged with the cam 12 may be a notch portion of the receiving slot, so as to reduce the possibility that the cam 12 contacts with other portions of the slider 11 except the rotating element 1122 to generate plastic particles, and the possibility of blocking with other portions.

It should be noted that, no matter whether the connection member 1121 is rotatably connected or fixedly connected to the mounting portion 1111, the contact portion between the mounting portion 1111 and the connection member 1121 may play a role in limiting the connection member 1121, and the connection member 1121 may play a role in limiting the rotation member 1122. The rotator 1122 is not easily separated from the slider body 111 by the restraining action of the connection member 1121 while being engaged with the cam 12.

In the technical solution of the embodiment of the present application, the slider 11 is configured to include the slider body 111 and the rotating component 112, the connecting part 1121 of the rotating component 112 is connected to the mounting portion 1111 of the slider body 111, and the rotating component 1122 is connected to the connecting part 1121, so that the rotating component 1122 can rotate around the connecting part 1121 or can rotate together with the connecting part 1121 to be rotationally matched with the cam 12, when the rotating component 1122 is rotationally matched with the cam 12, the friction between the two is small, and the probability of occurrence of the jam phenomenon is low. When the link 1121 is connected to the mounting portion 1111, the link 1121 can be restricted by the mounting portion 1111 and can restrict the rotor 1122, thereby reducing the possibility that the rotor 1122 is disengaged from the slider body 111 and improving the reliability of the rotational engagement of the rotor 1122 with the cam 12.

According to other embodiments of the present application, fig. 3 is an exploded view of the first slider 11 according to some embodiments of the present application, when the connection member 1121 is fixedly connected to the mounting portion 1111 and the rotating member 1122 is rotatably connected to the connection member 1121, as shown in fig. 3, the mounting portion 1111 has a mounting through hole a, the connection member 1121 is interference-connected to the mounting portion 1111 through the mounting through hole a, the rotating member 1122 has a connecting through hole b, and the connection member 1121 is rotatably connected to the rotating member 1122 through the connecting through hole b.

One or two mounting through-holes a may be provided in the mounting portion 1111. The mounting manner of the mounting portion 1111, the connection member 1121 and the rotation member 1122 is different depending on the number of the mounting through holes a.

In some embodiments, when there is one mounting through hole a, during the process of assembling the mounting portion 1111, the connecting member 1121, and the rotating member 1122, the rotating member 1122 may be first placed in the receiving groove, and the mounting through hole a corresponds to the connecting through hole b, and then one end of the connecting member 1121 passes through the mounting through hole a and extends into the connecting through hole b, so as to achieve the interference connection between the mounting portion 1111 and the connecting member 1121, and the rotational connection between the connecting member 1121 and the rotating member 1122. In this embodiment, it should be noted that the size of the connection part 1121 protruding into the connection through hole b may be set to be larger, so as to reduce the possibility that the rotation part 1122 is separated from the connection part 1121 during the rotation process.

In other embodiments, when the two installation through holes a are provided, the installation through holes a may include a first installation through hole and a second installation through hole which are oppositely disposed, and in the process of assembling the installation portion 1111, the connection member 1121 and the rotation member 1122, the rotation member 1122 may be placed in the receiving groove at first, and then one end of the connection member 1121 passes through the first installation through hole and the connection through hole b and extends into the second installation through hole, so that the other end of the connection member 1121 is located at the first installation through hole, thereby achieving interference connection between the installation portion 1111 and the connection member 1121, and rotation connection between the connection member 1121 and the rotation member 1122. In this embodiment, since both ends of the link 1121 are connected to the mounting portions 1111, the mounting portions 1111 can restrict both ends of the link 1121 so that the rotor 1122 does not come off the link 1121.

It should be noted that in both embodiments, the inner diameter of the connecting through hole b is larger than the inner diameter of the mounting through hole a, so that the connection member 1121 can be rotatably connected to the rotation member 1122 after extending into the connecting through hole b. In addition, the end surface of the other end of the attachment 1121, which does not pass through the mounting through-hole a, is disposed flush with the outer surface of the mounting portion 1111, so that the attachment 1121 can be prevented from affecting the sliding of the slider 11.

In the technical scheme of this application embodiment, connecting piece 1121 can be connected with installation department 1111 interference through mounting through-hole a, and can rotate with rotation piece 1122 through connect through-hole b and be connected, can rotate around connecting piece 1121 when rotating piece 1122 and cam 12 normal running fit. In addition, when the connection member 1121 is fixedly connected to the mounting portion 1111, the mounting portion 1111 can completely restrict the connection member 1121, and the connection member 1121 can restrict the rotation member 1122, so that the possibility that the rotation member 1122 is separated from the slider body 111 is reduced, and the reliability of the rotation engagement of the rotation member 1122 with the cam 12 is improved.

According to other embodiments of the present application, fig. 4 is an exploded view of a second slider 11 according to an embodiment of the present application, when the connection member 1121 is rotatably connected to the mounting portion 1111 and the rotating member 1122 is fixedly connected to the connection member 1121, as shown in fig. 4, the mounting portion 1111 has a mounting groove c, a notch of the mounting groove c faces the same direction as a notch of the mounting groove, the connection member 1121 enters the mounting groove c along the notch of the mounting groove c to be rotatably connected to the mounting portion 1111, the end of the rotating member 1122 close to the connection member 1121 has a connection groove d, and the connection member 1121 is in interference connection with the rotating member 1122 through the connection groove d.

The connection groove d is a structure for connecting the connection member 1121. The connection groove d may be a through groove penetrating the rotation member 1122, or may include a first connection groove and a second connection groove that do not penetrate the rotation member 1122. When the connection slot d is configured as a through slot, the connection part 1121 may be interference-fitted with the rotation part 1122 through the connection slot d. When the connecting slot d includes a first connecting slot and a second connecting slot, the connecting part 1121 may also include a first connecting part and a second connecting part, the first connecting part may be connected to one end of the rotating part 1122 through the first connecting slot in an interference manner, the second connecting part may be connected to the other end of the rotating part 1122 through the second connecting slot in an interference manner, and after the first connecting part, the second connecting part and the rotating part 1122 are connected in an interference manner, axes of the first connecting part, the second connecting part and the rotating part 1122 may be on a straight line.

Further, in the direction perpendicular to the axis of the rotating member 1122, the size of the connecting member 1121 may be set to be slightly larger than the size of the connecting slot d, for example, when the size of the mounting slot c is set to be 2.5 mm, the size of the connecting member 1121 may be set to be 2.6 mm, so that the connecting member 1121 and the rotating member 1122 may be in interference connection, and there is no gap between the two, so that the connecting member 1121 cannot be separated from the mounting slot c in the axis direction of the rotating member 1122, which is beneficial to improving the reliability of the interference connection between the connecting member 1121 and the rotating member 1122.

The mounting groove c is a structure for mounting the connection member 1121. One or two mounting grooves c can be arranged. Taking the placement position in fig. 3 as an example, when one mounting groove c is provided, the mounting groove c may be provided at an upper portion or a lower portion of the mounting portion 1111, and when two mounting grooves c are provided, the mounting groove c may include a first mounting groove and a second mounting groove which are oppositely provided in an up-down direction.

In this embodiment, in the process of assembling the installation portion 1111 and the connection member 1121 and rotating member 1122, the connection member 1121 and the rotating member 1122 may be connected in an interference manner, the rotating member 1122 and the connection member 1121 are installed in the installation portion 1111 through the notch of the installation groove c and the notch of the installation groove, and when one installation groove c is provided, one end of the connection member 1121 is located in the installation groove c, the other end of the connection member is in contact with the groove wall of the installation groove c, and when two installation grooves c are provided, the end of the connection member 1121, which is far away from the rotating member 1122, is located in the first installation groove and the second installation groove respectively.

In the technical scheme of this application embodiment, connecting piece 1121 can rotate with installation department 1111 through mounting groove c and be connected, and can rotate 1122 fixed connection through connecting groove d and rotation piece 1122, can rotate the piece 1122 with cam 12 normal running fit time and rotate together with connecting piece 1121. In addition, when the connection member 1121 is rotatably connected to the mounting portion 1111, the mounting portion 1111 may limit the movable range of the connection member 1121 through the mounting groove c, thereby reducing the possibility that the rotation member 1122 is separated from the slider body 111 and improving the reliability of the rotation engagement of the rotation member 1122 and the cam 12.

It should be noted that, in the above embodiment, the rotating element 1122 may not be provided with the connecting slot d, but may be integrally formed with the connecting element 1121. In this way, the rotor 1122 can be fixedly connected to the connection member 1121.

According to other embodiments of the present application, please continue to refer to fig. 4, the mounting groove c is a U-shaped groove.

Based on the above statement, the rotating element 1122 and the cam 12 are rotationally engaged at the notch of the receiving slot, therefore, when the mounting slot c is configured as a U-shaped slot, after the connecting element 1121 and the rotating element 1122 are mounted in the mounting portion 1111, in the process of rotationally engaging the rotating element 1122 with the cam 12, the cam 12 applies a force to the rotating element 1122 toward the rotating element 1122, and the rotating element 1122 applies a force to the connecting element 1121 after receiving the force.

According to other embodiments of the present application, fig. 5 is a schematic size diagram of the mounting groove c, the connection member 1121 and the rotation member 1122 according to some embodiments of the present application. As shown in FIG. 5, the notch dimension L of the mounting groove c is along the first direction X ₁ Dimension L of attachment 1121 ₂ Inner dimension L of mounting groove c ₃ And dimension L of rotor 1122 ₄ Is configured to satisfy: l is ₁ ＜L ₂ ＜L ₃ ＜L ₄ (ii) a The first direction X is substantially perpendicular to the opening of the mounting groove c and substantially parallel to the plane of the mounting groove c.

Along the first direction X, the size of the notch of the mounting groove c refers to the size of a connecting line between two opposite walls of the notch of the mounting groove c along the first direction X; the dimension of the mounting groove c in the groove refers to a dimension of a connecting line between two walls of the mounting groove c which are opposite to each other in the first direction X. It should be noted that there may be a plurality of lines connecting the two walls of the notch portion along the first direction X and the two walls in the slot along the first direction X, however, when the connection piece 1121 is located in the notch, the maximum dimension (diameter) of the connection piece 1121 along the first direction X should be larger than the notch dimension, and when the connection piece 1121 is located in the slot, each dimension of the connection piece 1121 along the first direction X should be smaller than the corresponding line dimension in the slot.

Substantially perpendicular means that the angle between the first direction X and the orientation of the notch of the mounting groove c is greater than or equal to 80 ° and less than or equal to 100 °. Substantially parallel means that the angle between the first direction X and the plane in which the mounting groove c lies is less than or equal to 15 °.

Based on the foregoing statement, since the connection member 1121 and the rotation member 1122 enter inside the mounting groove c along the notch of the mounting groove c, if along the first direction X, the notch dimension L of the mounting groove c ₁ Is greater than dimension L of attachment 1121 ₂ Then, when the rotating member 1122 and the connecting member 1121 are mounted to the mounting portion 1111 and are not rotationally engaged with the cam 12, the connecting member 1121 and the rotating member 1122 are easily separated from the mounting portion 1111 along the notch of the mounting groove c and the notch of the receiving groove; alternatively, during use, the rotor 1122 and the link 1121 are easily separated from the mounting portion 1111 when the slider body 111 is moved toward the cam 12 by an external force.

Therefore, along the first direction X, the size L of the notch of the mounting groove c ₁ Is smaller than the dimension L of the connecting member 1121 ₂ At this time, the wall of the notch of the mounting groove c restricts the connection member 1121, so that the rotation member 1122 and the connection member 1121 are not easily separated from the mounting portion 1111 regardless of whether the rotation member 1122 is rotatably engaged with the cam 12 or whether the slider body 111 slides by an external force.

In addition, if along the first direction X, the dimension L of the connection part 1121 ₂ Greater than the in-groove dimension L of the mounting groove c ₃ Then, when the connection member 1121 enters the groove of the mounting groove c, the inner wall of the groove restricts the connection member 1121, so that the connection member 1121 cannot be rotatably connected with the mounting portion 1111.

Thus, along the first direction X, the dimension L of the connection member 1121 is defined as ₂ Is smaller than the inner dimension L of the mounting groove c ₃ In the meantime, the connection part 1121 may have a certain rotation space in the mounting groove c to realize connectionThe hinge 1121 is rotatably connected to the mounting portion 1111.

Further, along the first direction X, the dimension L of the rotating member 1122 ₄ Inner dimension L smaller than mounting groove c ₃ In this case, the connecting member 1121 and the rotating member 1122 may be separated from the mounting groove c in the axial direction, which is not favorable for assembling the rotating member 112 to the mounting portion 1111 and for rotationally coupling the rotating member 1122 to the cam 12.

Thus, in the first direction, when the dimension L of the rotating member ₄ Greater than the in-groove dimension L of the mounting groove c ₃ In this case, the connection member 1121 and the rotation member 1122 do not come out from the groove of the mounting groove c along the axial direction, which is beneficial to improving the assembling reliability of the rotation member 112 and the mounting portion 1111 and the reliability of the rotation fitting of the rotation member 1122 and the cam 12.

According to other embodiments of the present application, please continue to refer to fig. 5, the notch portion of the installation groove c is provided with a guiding angle α.

The guide angle α is an angle for guiding the link. The guide angle α may be set to an obtuse angle.

When the connection member 1121 enters the mounting groove c along the notch of the mounting groove c, the guide angle α guides the connection member, so as to facilitate the assembly of the connection member 1121 and the mounting portion 1111.

Further, when the guide angle α is set to an arc angle, the guide angle α also reduces the possibility that the wall at the notch of the mounting groove c will scratch the connection member 1121.

According to other embodiments of the present application, fig. 6 is a schematic view of the mounting portion 1111 in some embodiments of the present application, as shown in fig. 6, the mounting portion 1111 includes a first limiting wall a, a second limiting wall B and a third limiting wall C, the first limiting wall a is opposite to the second limiting wall B, and the third limiting wall C is connected between the first limiting wall a and the second limiting wall B; the first limiting wall A, the second limiting wall B and the third limiting wall C enclose the barrier to form an accommodating groove.

The first, second, and third limiting walls a, B, and C are walls for forming the receiving groove, and are also walls for limiting the rotary member 1122 when the rotary member 1122 rotates. In addition, the first limiting wall a and the second limiting wall B are also walls for installing the connection member 1121, and the installation through hole a or the installation groove c described above may be provided on the first limiting wall a and/or the second limiting wall B.

When first spacing wall A, second spacing wall B and third spacing wall C formed the holding tank, first spacing wall A can be the upper wall of holding tank, and second spacing wall B can be the lower wall of holding tank, and third spacing wall C can be the lateral wall of holding tank. Specifically, one side of the third limiting wall C facing the notch of the receiving groove may be set to be arc-shaped to match with the rotating member 1122, so as to limit and guide the rotating member 1122 when the rotating member 1122 rotates.

When the rotating member 1122 is limited by the first limiting wall a, the second limiting wall B and the third limiting wall C, specifically, in the rotating process of the rotating member 1122, the rotating member 1122 can be limited by the first limiting wall a and the second limiting wall B in the up-down direction, the probability that the rotating member 1122 and the cam 12 are dislocated and not contacted in the up-down direction is reduced, the rotating member 1122 can be limited by the third limiting wall C to move in the direction away from the cam 12, and the rotating member 1122 can be always in running fit with the cam 12 in the rotating process.

According to other embodiments of the present application, please continue to refer to fig. 6, a first arc-shaped transition surface D is disposed at an end of the first limiting wall a close to the notch of the accommodating groove, and a second arc-shaped transition surface E is disposed at an end of the second limiting wall B close to the notch of the accommodating groove.

The first and second arc-shaped transition surfaces D and E are surfaces that contact the cam 12 when the rotor 1122 is misaligned with the cam 12.

According to the difference of the structures arranged on the first limiting wall A and the second limiting wall B, the arrangement quantity of the first arc-shaped transition surface D and the second arc-shaped transition surface E is also different. For example, when the first limiting wall a and/or the second limiting wall B are provided with the mounting through holes a, one of the first arc-shaped transition surface D and the second arc-shaped transition surface E may be provided. When first spacing wall A and second spacing wall B all set up mounting groove c, first arc transition face D and second arc transition face E all can set up two.

Since the rotating member 1122 is rotatably engaged with the cam 12 at the notch portion of the receiving groove, the cam 12 may contact with the first stopper wall a or the second stopper wall B when the cam 12 is displaced in the axial direction thereof during the rotation engagement.

Based on this, if the first and second limiting walls a and B pass through sharp corners near the notch portions of the receiving groove, the first and second limiting walls a and B may limit the rotation of the cam 12 and even damage the cam 12.

Therefore, in the technical scheme of this embodiment, when the cam 12 contacts the first limiting wall a and the second limiting wall B, the cam 12 can contact the first arc-shaped transition surface D and the second arc-shaped transition surface E, so that the jamming phenomenon is not easy to occur between the first limiting wall a and the cam 12 and between the second limiting wall B and the cam 12, or the cam 12 is not easy to be damaged by the first limiting wall a and the second limiting wall B.
