Description

Technical Field

[0001] This invention relates to the field of household appliance technology, and more specifically to rotary switches and devices having rotary switches. Background Technology

[0002] Rotary switches are common components in household appliances such as electric heaters and air conditioners, used to control power levels. They consist of a spindle, an auxiliary stationary contact, a moving contact, and a power level contact, all sequentially mounted on the spindle. The auxiliary stationary contact is in contact with the moving contact. As the spindle rotates to different angles, the moving contact contacts the corresponding power level contact, thus switching between different power levels. If the auxiliary stationary contact deforms, good contact cannot be achieved when switching power levels, resulting in no power or poor contact. Summary of the Invention

[0003] In view of this, the present invention provides a rotary switch and a device having a rotary switch to solve the problem of poor contact.

[0004] In a first aspect, the present invention provides a rotary switch, comprising: a spindle, a position stationary contact, and an auxiliary stationary contact, a first moving contact, and a second moving contact sequentially disposed on the spindle, wherein the auxiliary stationary contact is provided with reinforcing ribs.

[0005] Beneficial effects: By setting reinforcing ribs on the auxiliary stationary plate, the strength of the auxiliary stationary plate can be increased, effectively solving the problem of easy deformation of the auxiliary stationary plate during the assembly of the rotary switch, and improving the phenomenon of poor contact when the rotary switch is rotated.

[0006] In one alternative embodiment, the auxiliary stationary plate includes a central hole adapted to pass through the mandrel, and the reinforcing rib is located near the central hole.

[0007] Beneficial effects: By setting reinforcing ribs on the auxiliary stationary plate and placing the reinforcing ribs close to the center hole, the strength of the auxiliary stationary plate is increased, which effectively solves the problem of easy deformation of the auxiliary stationary plate during the assembly of the rotary switch and improves the phenomenon of poor contact when the rotary switch is rotated.

[0008] In related technologies, during the assembly of rotary switches, the auxiliary stationary plate may sink and bend, specifically manifested as a central depression and a raised tail end. Therefore, this embodiment brings the reinforcing rib closer to the central hole. Compared with related technologies, this can increase the strength of the auxiliary stationary plate, effectively solve the problem of easy deformation of the auxiliary stationary plate during the assembly of rotary switches, and improve the phenomenon of poor contact when the rotary switch is rotated.

[0009] In one alternative embodiment, the reinforcing rib extends radially along the central hole and is located on the central symmetry plane of the auxiliary stationary plate.

[0010] Beneficial effects: Since the reinforcing rib is located on the central symmetrical plane of the auxiliary stationary plate, the entire auxiliary stationary plate is subjected to balanced forces and has good strength. This effectively solves the problem of easy deformation of the auxiliary stationary plate during the assembly of the rotary switch and improves the phenomenon of poor contact when the rotary switch is rotated.

[0011] In one optional embodiment, the distance between the reinforcing rib and the central hole is L1, where 0.8mm ≤ L1 ≤ 1.2mm.

[0012] Beneficial effects: In related technologies, during the assembly of rotary switches, the auxiliary stationary plate is prone to sinking and bending deformation, specifically manifested as a central depression and a raised tail end. Therefore, compared with related technologies, the distance between the reinforcing rib and the central hole in this embodiment is smaller and closer to the central hole. Compared with related technologies, this embodiment can increase the strength of the auxiliary stationary plate, effectively solve the problem of easy deformation of the auxiliary stationary plate during the assembly of rotary switches, and improve the phenomenon of poor contact when the rotary switch is rotated.

[0013] In one alternative implementation, L1 is 1 mm.

[0014] Beneficial effects: The distance between the reinforcing rib and the center hole is only 1mm, which is close to the center hole. Compared with related technologies, this can increase the strength of the auxiliary stationary plate, effectively solve the problem of easy deformation of the auxiliary stationary plate during the assembly of the rotary switch, improve the poor contact phenomenon when the rotary switch is rotated, and facilitate the processing to form the reinforcing rib.

[0015] In one optional embodiment, the reinforcing rib has a length of L2, a width of d1, and a thickness of d2, with 6.6mm≤L2≤7mm, 0.8mm≤d1≤1.2mm, and 0.3mm≤d2≤0.5mm.

[0016] Beneficial effects: The reinforcing ribs have sufficient length and width, and are not too thick. While ensuring the strength of the auxiliary stationary plate, they will not affect the installation of other components. This effectively solves the problem of easy deformation of the auxiliary stationary plate during the assembly of the rotary switch and improves the phenomenon of poor contact when the rotary switch is rotated.

[0017] In one alternative implementation, L2 is 6.8 mm, d1 is 1 mm, and d2 is 0.4 mm.

[0018] Beneficial effects: The reinforcing ribs have sufficient length and width, and are not too thick. While ensuring the strength of the auxiliary stationary plate, they will not affect the installation of other components. This effectively solves the problem of easy deformation of the auxiliary stationary plate during the assembly of the rotary switch and improves the phenomenon of poor contact when the rotary switch is rotated.

[0019] In one optional embodiment, the middle part of the auxiliary stationary piece is folded upward to form an annular convex edge, the inner side of the annular convex edge forms the central hole, and the connection between the annular convex edge and the auxiliary stationary piece is provided with a chamfer;

[0020] The reinforcing ribs are chamfered.

[0021] Beneficial effects: The chamfered design further increases the strength of the auxiliary stationary plate, effectively solving the problem of easy deformation of the auxiliary stationary plate during rotary switch assembly and improving the poor contact phenomenon when the rotary switch is in different positions. The chamfered design of the reinforcing ribs disperses the stress on the ribs, making them less prone to deformation.

[0022] In one optional embodiment, the first movable piece includes a first flat portion and a bent portion connected to one side of the first flat portion. The first flat portion is provided with a first protrusion, which contacts the auxiliary stationary piece. The second movable piece contacts the lower surface of the bent portion away from the first flat portion, and the second movable piece is adapted to contact the gear position stationary contact piece.

[0023] Beneficial effects: By setting a bent portion on one side of the first plane, and having the side of the bent portion away from the first plane in contact with the second moving piece, compared with related technologies, the phenomena of no power supply and poor contact can be avoided because the first and second moving pieces have a larger contact area.

[0024] In one alternative embodiment, the bending portion includes an inclined portion that is set at an angle.

[0025] In one alternative embodiment, the bent portion further includes a second planar portion connected to the side of the inclined portion away from the first planar portion, and the second movable piece contacts the lower surface of the second planar portion.

[0026] Beneficial effects: By providing an inclined portion on one side of the first plane and a second plane portion on the side of the inclined portion away from the first plane, and the second plane portion contacting the second moving piece, compared with related technologies, the phenomenon of no power supply and poor contact can be avoided because the first moving piece and the second moving piece have a larger contact area.

[0027] In addition, the inclined part gives the first moving piece a certain degree of elasticity, which can further ensure contact with the second moving piece and avoid the phenomenon of no power supply and poor contact.

[0028] In one optional embodiment, the bent portion is trapezoidal, the side length of the bent portion away from the first planar portion is less than the side length of the side connected to the first planar portion, and the included angle between the extension lines of the two sides of the bent portion is A, where A is 41°.

[0029] Beneficial effect: This setting ensures that the side of the bent portion away from the first plane portion can fully cover the second moving piece, achieving better contact.

[0030] In one optional embodiment, the angle between the inclined portion and the plane containing the first planar portion is B, where 5°≤B≤10°.

[0031] Beneficial effects: The angle between the inclined part and the plane where the first flat part is located is small, and the first moving piece occupies less space in the height direction, so it will not affect the installation of other components.

[0032] In one alternative implementation, B is 7°.

[0033] Beneficial effects: The angle between the inclined part and the plane where the first flat part is located is only 7°, and the first moving piece occupies less space in the height direction, so it will not affect the installation of other components.

[0034] Secondly, the present invention also provides a device having a rotary switch, comprising: the rotary switch. Attached Figure Description

[0052] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0053] In related technologies, such as Figures 1 to 3 As shown, the rotary switch includes a cover plate 1a, a shaft core 2a, a spring 3a, a steel ball 4a, a top spring 5a, an auxiliary stationary plate 6a, a wire retaining spring 7a, a first moving plate 8a, a second moving plate 9a, a base 10a, a position stationary contact plate 11a, a first arc-shaped stationary contact plate 12a, a second arc-shaped stationary contact plate 13a, a connecting plate 14a, and a wire retaining spring folded edge 15a.

[0054] The shaft core 2a is rotatably mounted in the cover plate 1a and the base 10a. The spring 3a is mounted in the mounting groove of the shaft core 2a. One end of the spring 3a abuts against the steel ball 4a. The mounting groove of the shaft core 2a is installed in the inner octagonal arc structure of the cover plate 1a. By rotating the shaft core 2a, the steel ball 4a slides, causing the mounting groove of the shaft core 2a to turn to different octagonal arc positions. A top spring 5a is sleeved on the outside of the shaft core 2a, with its lower end abutting against the auxiliary stationary plate 6a. The auxiliary stationary plate 6a is secured in the mounting groove on the side of the mounting hole of the cover plate 1a by a wire-clamping spring 7a. The first moving plate 8a and the second moving plate 9a are sequentially inserted through the outside of the shaft core 2a. The two first protrusions 801a of the first moving plate 8a contact the auxiliary stationary plate 6a, and the two second protrusions 802a contact the upper surface of the second moving plate 9a. Three wire-clamping springs 7a fix the gear position stationary contact plate 11a in the base 10a, one wire-clamping spring 7a fixes the first arc-shaped stationary contact plate 12a in the base 10a, and one wire-clamping spring 7a fixes the second arc-shaped stationary contact plate 13a in the base 10a. After assembly, the lower protrusion of the edge of the first moving plate 8a contacts the first arc-shaped stationary contact plate 12a, and the two lower protrusions of the second moving plate 9a contact the gear position stationary contact plate 11a and the second arc-shaped stationary contact plate 13a, respectively. When the horizontal end of the shaft 2a is parallel to the mounting screw of the top cover, the switch is in the initial off position. When the shaft 2a rotates clockwise by 45°, 90°, and 135°, the stationary contact 11a and the second arc-shaped stationary contact 13a respectively contact the two lower protrusions of the second moving contact 9a. When the shaft 2a rotates to 180°, the switch is off. When the shaft 2a rotates counterclockwise by 45°, 90°, and 135°, the stationary contact 11a and the second arc-shaped stationary contact 13a respectively contact the two lower protrusions of the second moving contact 9a, and the lower protrusion of the first moving contact 8a contacts the first arc-shaped stationary contact. When this rotary switch is used with a fan, the stationary contact can be connected to the corresponding fan speed, the second arc-shaped stationary contact 13a can be connected to the negative ion function (the negative ion function will be activated as long as the fan is running), and the first arc-shaped stationary contact 12a can be connected to the oscillation function (clockwise rotation of the speed setting causes the fan to oscillate, and counterclockwise rotation selects the speed setting for oscillation).

[0055] In related technologies, during the assembly of a rotary switch, after the wire is inserted, the auxiliary stationary piece 6a sinks and shifts, resulting in poor contact. The cause is that the auxiliary stationary piece 6a sinks and bends, specifically manifested as a central depression and a raised tail end. After the cover plate 1a is placed on top of the raised tail end, it presses down on the first moving piece 8a, causing the other end of the first moving piece 8a to also raise. Additionally, as... Figure 3 As shown, the first movable piece 8a includes a first flat portion, which has two upward-facing first protrusions 801a and two downward-facing second protrusions 802a. The second protrusions 802a contact the second movable piece 9a. Therefore, the contact area between the first movable piece 8a and the second movable piece 9a is small. When the first movable piece 8a tilts up, it cannot maintain contact with the second movable piece 9a. This will eventually cause it to fail to make good contact with the gear position stationary contact piece 11a when switching to a gear position, resulting in no power and poor contact.

[0113] In this embodiment, the reinforcing rib 601 has sufficient length and width, and its thickness is not too thick. Under the premise of ensuring the strength of the auxiliary stationary piece 6, it will not affect the installation of other components. This effectively solves the problem of easy deformation of the auxiliary stationary piece 6 during the assembly of the rotary switch and improves the phenomenon of poor contact when the rotary switch is rotated.

[0114] In one embodiment, the middle part of the auxiliary stationary piece 6 is folded upward to form an annular protrusion 603, the inner side of the annular protrusion 603 forms a central hole 602, and a chamfer is provided at the connection between the annular protrusion 603 and the auxiliary stationary piece 6.

[0115] In this embodiment, the chamfering can further increase the strength of the auxiliary stationary piece 6, effectively solving the problem of easy deformation of the auxiliary stationary piece 6 during the assembly of the rotary switch, and improving the phenomenon of poor contact when the rotary switch is in the rotation position.

[0116] In one embodiment, the reinforcing rib 601 has a chamfer.

[0117] In this embodiment, the reinforcing rib 601 is chamfered, which can disperse the stress of the reinforcing rib 601 and make it less prone to deformation.

[0118] In one embodiment, such as Figure 5 As shown, the auxiliary stationary plate 6 includes a horizontal connecting portion 600 and a vertical connecting portion 604 connected to one end of the horizontal connecting portion. The connection between the horizontal connecting portion 600 and the vertical connecting portion 604 is chamfered, which is used to increase strength by adding material. The reinforcing rib 601 and the center hole 602 are both provided in the horizontal connecting portion 600.

[0119] In one embodiment, the first movable piece 8 includes a first flat portion 801 and a bent portion connected to one side of the first flat portion 801. The first flat portion 801 is provided with a first protrusion 804, which contacts the auxiliary stationary piece 6. The second movable piece 9 contacts the lower surface of the bent portion away from the first flat portion 801, and the second movable piece 9 is adapted to contact the gear position stationary contact piece 11.

[0120] In this embodiment, by providing a bent portion on one side of the first plane, and having the side of the bent portion away from the first plane in contact with the second movable piece, the phenomenon of no power supply and poor contact can be avoided compared with related technologies because the first and second movable pieces have a larger contact area.

[0121] In one embodiment, the bending portion includes an inclined portion 802 that is inclined.

[0122] In one embodiment, such as Figure 8 , Figure 9As shown, the bent portion also includes a second flat portion 803 connected to the side of the inclined portion 802 away from the first flat portion 801, and the second moving piece 9 contacts the lower surface of the second flat portion 803.

[0123] In this embodiment, by providing an inclined portion 802 on one side of the first plane and a second flat portion 803 on the side of the inclined portion 802 away from the first plane, and the lower surface of the second flat portion 803 contacting the second movable piece 9, compared with related technologies, since the first movable piece 8 and the second movable piece 9 have a larger contact area, the phenomenon of no power supply and poor contact can be avoided.

[0124] In addition, the inclined part 802 makes the first moving piece 8 have a certain elasticity, which can further ensure contact with the second moving piece 9 and avoid the phenomenon of no power supply and poor contact.

[0125] It should be noted that in related technologies, the two downward-facing second protrusions contact the second moving piece 9. In this embodiment, the inclined portion 802 ensures that the second flat portion 803 contacts the second moving piece 9.

[0126] In an alternative embodiment, such as Figure 11 As shown, the bending portion includes only the inclined portion 802 that is inclined.

[0127] Specifically, such as Figure 8 , Figure 9 , Figure 11 As shown, the inclined portion 802 is inclined downward relative to the first planar portion 801.

[0128] In one embodiment, such as Figure 10 and Figure 12 The bent portion shown is trapezoidal. The side length of the bent portion away from the first plane portion 801 is less than the side length connected to the first plane portion 801. The included angle between the extension lines of the two sides of the bent portion is A, and A is 41°.

[0129] In this embodiment, it can be ensured that the side of the bent portion away from the first flat portion 801 can fully cover the second moving piece 9, achieving better contact.

[0130] In one embodiment, such as Figure 4 As shown, the rotary switch includes a cover plate 1, a spindle 2, a spring 3, a steel ball 4, a top spring 5, an auxiliary stationary plate 6, a wire retaining spring 7, a first moving plate 8, a second moving plate 9, a base 10, a position stationary contact plate 11, a first arc-shaped stationary contact plate 12, a second arc-shaped stationary contact plate 13, a connecting plate 14, and a wire retaining spring folded edge 15.

[0131] The spindle 2 is rotatably mounted in the cover plate 1 and the base 10. The spring 3 is mounted in the mounting groove of the spindle 2, with one end of the spring 3 abutting against the steel ball 4. The mounting groove of the spindle 2 is installed in the inner octagonal arc structure of the cover plate 1. Rotating the spindle 2 causes the steel ball 4 to slide, allowing the mounting groove of the spindle 2 to turn to different octagonal arc positions. The top spring 5 is sleeved on the outside of the spindle 2, with its lower end abutting against the auxiliary stationary plate 6. The auxiliary stationary plate 6 is clamped in the mounting groove on the side of the mounting hole of the cover plate 1 by the wire clamping spring 7. The first moving plate 8 and the second moving plate 9 are sequentially inserted through the outside of the spindle 2. The two first protrusions 804 of the first moving plate 8 contact the auxiliary stationary plate 6, and the second flat part 803 contacts the upper surface of the second moving plate 9. Three wire clamping springs 7 fix the stop stationary contact plate 11 in the base 10, one wire clamping spring 7 fixes the first arc-shaped stationary contact plate 12 in the base 10, and one wire clamping spring 7 fixes the second arc-shaped stationary contact plate 13 in the base 10. After assembly, the lower protrusion of the edge of the first moving piece 8 contacts the first arc-shaped stationary contact piece 12, and the two lower protrusions of the second moving piece 9 contact the gear position stationary contact piece 11 and the second arc-shaped stationary contact piece 13, respectively. When the horizontal end of the spindle 2 is parallel to the mounting screw of the upper cover, the switch is in the initial off position. When the spindle 2 rotates clockwise by 45°, 90°, and 135°, the gear position stationary contact piece 11 and the second arc-shaped stationary contact piece 13 contact the two lower protrusions of the second moving piece 9, respectively. When the spindle 2 rotates to 180°, the switch is off. When the spindle 2 rotates counterclockwise by 45°, 90°, and 135°, the gear position stationary contact piece 11 and the second arc-shaped stationary contact piece 13 contact the two lower protrusions of the second moving piece 9, and the lower protrusion of the first moving piece 8 contacts the first arc-shaped stationary contact piece. When this rotary switch is used on a fan, the gear position contact can be connected to the corresponding gear position of the fan, the second arc-shaped contact 13 can be connected to the negative ion function (the negative ion function can be turned on as long as the fan is running), and the first arc-shaped contact 12 is connected to the oscillation function (rotating the gear clockwise will cause the fan to oscillate, and rotating it counterclockwise will cause the fan to oscillate).
