Description

Technical Field

[0001] This invention relates to the field of electrical switch technology, and more specifically, to a rotary switch and its operating mechanism. Background Technology

[0002] A rotary electrical switch uses a rotary switch to drive a rotating shaft to rotate, which in turn drives a rotating switching structure to switch the electrical position.

[0003] The existing rotary switch includes a top cover and a mounting base. A drive disk and a rotating base are arranged inside the mounting base, and an energy storage element is arranged between the two. The drive disk rotates to store energy in the energy storage element, which in turn presses the rotating base to rotate and switch positions. During this process, the energy storage element releases energy, which drives the rotating base to twist and achieves electrical position switching.

[0004] In existing mechanisms, the input component (drive disc) and output component (rotor) are in contact when transmitting torque. When non-professionals perform rotational operations, there may be a situation where pressure is applied while rotating (i.e., additional pressure is applied axially during rotation). This increases the friction between the output component, input component, and base, which in turn reduces the rotational speed of the rotor during switching, leading to accelerated switch erosion. In severe cases, the rotor may even fail to rotate, causing switch failure and posing a risk of personal injury and property damage.

[0005] After the existing mechanism switches over the dead point, the displacement component bears the impact, which places high demands on the strength of the displacement component. Even if the strength is sufficient, the lifespan is often limited, leading to mechanism failure. Some mechanisms also have stop components, but the two parts of the stop component that collide have high rigidity, resulting in a "hard-on-hard" collision. This causes a large bounce after the mechanism switches, which in turn causes the contacts to bounce significantly, leading to the burnout of the switch.

[0006] The existing mechanism has a complex structure, numerous parts, and cumbersome assembly procedures, resulting in large cumulative tolerances. This leads to a large fluctuation range in the number of latches during mechanism switching, causing problems such as latch instability and large fluctuations in lifespan. Summary of the Invention

[0043] This invention discloses an operating mechanism that improves the stability of the rotary switch shifting structure; this invention also provides a rotary switch.

[0044] 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, and 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.

[0045] like Figure 1 and Figure 2 As shown, Figure 1 Exploded view of the operating mechanism provided in this application; Figure 2 for Figure 1 A schematic diagram of the assembly structure of the operating mechanism.

[0046] In the rotary switch provided in this embodiment, a working cavity is formed between the cover plate 1 and the base 5. The driving force input component and the torque output component are arranged in the working cavity 501. The two transmit power to switch the switch position. Specifically, the input component is the drive disk 2, which is driven to rotate by the drive shaft 201. The output component is the rotating seat 4. An energy storage component 3 is arranged between the drive disk 2 and the rotating seat 4. During the rotation of the drive disk 2, energy is stored in the energy storage component 3. The rotating seat 4 continues to rotate at the point of change because the energy storage component releases energy, thereby realizing the switching of the switch position.

[0047] The rotary switch is operated by a mechanism for gear shifting. The base of the mechanism has a rotary seat cavity containing a rotary seat 4. A limiting part is arranged on the rotary seat cavity. The rotary seat has a displacement part that can be pressed or separated from the limiting part. The rotary seat is coupled with an energy storage component 3, which stores or releases mechanical energy to achieve rotation. A driving component stores energy in the energy storage component 3 and presses the displacement part to actuate. The driving component has a driving part and a pressing part. When the driving component is in the driving zone, the driving part displaces the energy storage component to store energy, during which the displacement part presses against the limiting part. When the driving component enters the pressing zone, the pressing part approaches and presses against the displacement part, causing the displacement part to separate from the limiting part. The rotary seat can then rotate freely, the energy storage component releases energy, and the rotary seat rotates, achieving gear shifting. By placing the limiting part on the base, the two directly form a snap-fit ​​structure. In the drive zone, the drive component only stores energy for the energy storage component. After entering the compression zone, the drive component acts on the displacement part, making the energy storage process and the compression process independent operating structures. This reduces the precision requirements for parts machining and assembly, and makes the gear switching drive structure of the rotary table more stable.

[0048] Specifically, the working chamber 501 is a rotating cavity in which the rotating seat 5 is driven to rotate to switch the switch position, and the rotating seat 4 is rotatably arranged in the rotating seat cavity.

[0049] In this embodiment, the driving component is a driving disk 2, which includes a driving disk body 200 and a rotating shaft 201 that drives the driving disk body 200 to rotate. The pressing part extends radially along the driving disk body 200, and the driving part 202 extends into the rotating seat 4 along the thickness direction of the driving disk body 200.

[0050] A limiting step 502 is provided on the base 5, which is arranged around the opening of the rotating seat cavity, and the pressing part overlaps on the limiting step 502.

[0051] The rotating seat 4 includes a bottom wall 401 and a cylindrical side wall 402. The displacement part extends along the arc direction of the cylindrical side wall 402 and can elastically deform along the axial direction of the rotating seat 4.

[0052] The extended end of the displacement part is provided with a raised displacement end (412a, 412b), the displacement end (412a, 412b) is provided with a displacement member fastening surface (422a, 422b), the limiting part is provided with a limiting member fastening surface (510a, 510b), and the displacement member fastening surface and the limiting member fastening surface are fastened together.

[0053] Inclined guide surfaces (432a, 432b) are provided between the displaced ends (412a, 412b) and the top surface of the rotary seat 4, and the pressing part presses against the displaced ends through the guide surfaces.

[0054] The drive disc 2 presses against the rotary seat 4 with its edge, and a limiting step 502 is set at the opening position of the rotary seat cavity, and the edge of the drive disc 2 overlaps on the limiting step 502.

[0055] An energy storage component 3 is arranged between the drive disk 2 and the rotating seat 4. The drive disk 2 rotates to store energy in the energy storage component 3. While storing energy, the energy storage component 3 pushes the rotating seat 4 to rotate. There is a rotation dead point between the drive disk 2 and the rotating seat 4. Before the rotating seat 4 passes the rotation dead point, the energy storage component 3 continues to store energy. After the drive disk 2 pushes the rotating seat 4 past the rotation dead point, the energy storage component 3 releases energy. The rotating seat 4 receives the energy released by the energy storage component 3, completes the displacement, and realizes the switching of the switch position.

[0056] like Figure 3 and Figure 4 As shown, Figure 3 for Figure 1 A schematic diagram of the drive disc structure of the central operating mechanism in the first direction; Figure 4 for Figure 3 Schematic diagram of the second direction of the drive disk structure.

[0057] Specifically, the drive disk 2 is connected to the drive disk body 200 by a rotating shaft 201. A first pressing part 200a and a second pressing part 200b extend from the drive disk body 200. The first pressing part 200a and the second pressing part 200b are on the same plate as the drive disk body 200.

[0058] The drive disk body 200 extends the drive part 202 towards the rotating seat side. The drive part 202 cooperates with the energy storage component 3. During the rotation of the drive disk 2, it compresses and stores energy on the energy storage component 3. The drive part 202 is located between the first compression part 200a and the second compression part 200b. It compresses and stores energy on the energy storage component 3 in both the forward and reverse directions of the rotating seat 4.

[0059] The drive disk 2 is supported axially by the first pressing part 200a and the second pressing part 200b on the limiting step 502. During the rotation of the drive disk 2 driven by the rotating shaft 201, the first pressing part 200a and the second pressing part 200b are supported axially by the limiting step 502. That is, the base 5 and the first pressing part 200a and the second pressing part 200b are in axial pressing cooperation, so that when the rotary switch is operated, the axial force transmitted by its rotation is transmitted to the base 5. The drive disk 2 and the rotary seat 4 do not transmit force axially, reducing the rotational friction between the drive disk 2 and the rotary seat 4 during the rotation. On this basis, after the rotary seat 4 receives the energy released by the energy storage component 3, its rotation process is in pressure with the drive disk 2. When the rotary seat 4 rotates to switch the switch position, the switching speed is increased, ensuring the breaking capacity of the switch and increasing the working life of the drive disk and the rotary seat.

[0060] like Figures 5-7 As shown, Figure 5 for Figure 1 A schematic diagram of the rotating structure of the operating mechanism; Figure 6 for Figure 5 A schematic diagram of the first direction structure of the transfer station; Figure 7 for Figure 5 A schematic diagram of the second direction structure of the transfer station.

[0061] In this embodiment, the rotary seat 4 includes a bottom wall 401 and a cylindrical side wall 402. The cylindrical side wall 402 is rotatably arranged within the rotary seat cavity. The cylindrical side wall 402 has a first displacement member 402a and a second displacement member 402b arranged in a basically symmetrical manner, with a displacement opening 402c between them. Both the first displacement member 402a and the second displacement member 402b can elastically jump along the axial direction of the rotary seat 4.

[0062] Specifically, a long slot 403 is formed on the cylindrical sidewall 402, extending through its wall thickness and along the arc direction. The portion of the rotating base 4 near its bottom wall forms a first sidewall surrounding the long slot. The first displacement member 402a and the second displacement member 402b form a second sidewall surrounding the long slot 403. A displacement opening 402c is provided between the first displacement member 402a and the second displacement member 402b. The arrangement of the long slot 403 and the displacement opening 402c allows the first displacement member 402a and the second displacement member 402b to be supported at both ends of the long slot 403 along its length, and to bounce along the width direction of the long slot 403 at the displacement opening 402c.

[0063] By utilizing the cylindrical sidewall 402 structure of the rotating seat 4, the outer diameters of the first displacement member 402a and the second displacement member 402b are arranged to be basically the same as the inner diameter of the rotating seat cavity of the base 5, thereby reducing the compressive intensity of axial compression deformation of the first displacement member 402a and the second displacement member 402b.

[0064] In this application, the first pressing part 200a and the second pressing part 200b are supported by the limiting step 502 at the opening position of the base 5. The pressing surfaces of the first pressing part 200a and the second pressing part 200b are the supporting end surfaces of the limiting step 502. When the rotary switch is used to switch gears, the first pressing part 200a cooperates with the first displacement member 402a, and the energy storage member 3 provides energy to drive the rotating seat 4 to rotate in the first direction; the second pressing part 200b cooperates with the second displacement member 402b, and the energy storage member 3 provides energy to drive the rotating seat 4 to rotate in the second direction.

[0065] The following describes the driving structure of the first pressing part 200a and the first displacement member 402a in detail. The driving structure of the second pressing part 200b and the second displacement member 402b is arranged in a basically symmetrical manner with the driving structure of the first pressing part 200a and the first displacement member 402a, and will not be described in detail here.

[0066] The drive disk 2 rotates, causing the first pressing part 200a to slide on the surface of the limiting step 502. The first pressing part 200a swings in a circular motion with the rotating shaft 201 of the drive disk 2 as the center of rotation. As the drive disk 2 rotates, its driving part 202 acts on the energy storage component 3, and the energy storage component 3 obtains the potential energy to drive the rotating seat 4 to rotate.

[0067] The purpose of energy storage component 3 is to provide energy for the rotation of rotary seat 4 to switch gears after the first compression part 200a passes through the rotation dead point. In this embodiment, the rotation dead point of rotary seat 4 is achieved by the limiting function of the first displacement component 402a and the first limiting component 500a.

[0068] The first displacement member 402a has a displacement end 412a, which has a raised structure. The height of the raised end 412a is higher than the upper surface of the rotating seat 4. At the same time, the first limiting member 500a is located on the upper surface of the base. In the rotation direction of the rotating seat 4, the first displacement member 402a is rotated and limited by the first limiting member 500a.

[0069] During the rotation of the drive disc 2, the first pressing part 200a presses the displacement end 412a of the first displacement member 402a, causing the first displacement member 402a to bend and deform into the interior of the rotary seat cavity. After the first displacement member 200a is pressed to the pressing end face 422a of the first pressing part 402a, the displacement end 412a of the first displacement member 402a is pressed into the lower end face of the first limiting member 500a. At this time, the first displacement member 402a can rotate freely in the rotation direction of the rotary seat 4, and the energy storage member 3 releases energy, causing the rotary seat 4 to rotate rapidly and switch gears.

[0070] Specifically, the displacement end 412a has a displacement member fastening surface 422a, and correspondingly, the first limiting member 500a has a limiting member fastening surface 510a. When the drive disk 2 rotates but does not reach the dead point of the rotary seat, the displacement member fastening surface 422a abuts against the limiting member fastening surface 510a, thereby restricting the rotation of the rotary seat 4.

[0071] like Figures 8-10 As shown, Figure 8 A schematic diagram showing the structural position of the operating mechanism provided in this application located at the first rotation dead point; Figure 9 A schematic diagram showing the structural position of the operating mechanism provided in this application after passing the first dead center of rotation; Figure 10 This is a schematic diagram of the structural position of the operating mechanism provided in this application after shifting gears in the first direction.

[0072] like Figure 8 As shown in A1, the drive disc 2 continues to rotate, and the first pressing part 200a applies axial pressure to the displacement end 412a of the first displacement member 402a. The upper end surface of the displacement end 412a that contacts the first pressing part 200a is provided with a guide surface 432a. This guide surface 432a is inclined upward from the upper end surface of the rotary seat 4 and connected to the top end surface of the displacement end 412a. This causes the first pressing part 200a to gradually compress and deform the displacement end surface, causing the displacement member latching surface 422a and the limiting member latching surface 510a to slide up and down and separate until the top end surface of the displacement end 412a falls into the lower end surface of the first limiting member 500a. The rotary seat is not obstructed in the rotation direction, the energy storage member 3 releases energy, and drives the rotary seat 4 to rotate rapidly to switch gears.

[0073] The rotary seat 4 can switch between a first direction and a second direction with the rotation direction set to forward and reverse to realize gear switching. Correspondingly, the base 5 is symmetrically arranged with a first limiting member 500a and a second limiting member 500b at intervals. The first limiting member 500a is provided with a first displacement member fastening surface 422a that cooperates with the first displacement member 402a and a first limiting member fastening surface 510a abutting structure. The second limiting member 500b is provided with a second displacement member fastening surface 422b that cooperates with the second displacement member 402b and a second limiting member fastening surface 510b abutting structure.

[0074] It is understandable that after the first displacement member 402a and the first limiting member 500a pass the rotation dead point along the first direction, when the rotary switch returns to its original position along the second direction, the guide surface 432a of the displacement end 412a contacts and engages with the first limiting member 500a. In order to facilitate the return of the first displacement member 402a to its initial position, a return slope 520a is provided on the return end face of the first limiting member 500a. The return slope 520a engages with the guide surface 432a of the displacement end 412a, thereby reducing the return resistance between the first displacement member 402a and the first limiting member 500a during the return process and reducing the difficulty of return.

[0075] Correspondingly, the second limiting member 500b is also provided with a return slope 520b, which cooperates with the second displacement member 412b to facilitate the rotation and return of the second displacement member 412b at the rotation dead point.

[0076] In this embodiment, the energy storage component 3 is an energy storage spring, which is an energy storage torsion spring. The energy storage torsion spring has a first torsion spring arm 301 and a second torsion spring arm 302 extending from its outer ring. A limiting post 404 is provided in the middle of the rotating seat 4 to limit the rotation of the energy storage torsion spring. A driving square hole 408 is provided at the bottom of the rotating seat 4. The shifting shaft of the rotary switch is installed in the driving square hole 408. The rotation of the rotating seat 4 transmits the rotation driving force through the driving square hole 408. The energy storage torsion spring is fitted on the limiting post 404. A torsion spring overlapping part 405 is provided in the middle of the rotating seat 4 away from the first shifting component 402a and the second shifting component 402b. After the energy storage torsion spring is fitted on the limiting post 404, the torsion spring overlapping part 405 falls between the first torsion spring arm 301 and the second torsion spring arm 302. The driving part 202 of the driving disk 2 extends into the rotating seat 4 and falls between the first torsion spring arm 301 and the second torsion spring arm 302. Preferably, the driving part 202 is a driving paddle with a thin sheet structure. The driving paddle has an arc surface structure, and its two sides in the width direction respectively abut against the first torsion spring arm 301 or the second torsion spring arm 302 to ensure the strength of the driving part 202 in plucking the energy storage torsion spring.

[0077] When the drive disc 2 rotates in the first direction (clockwise), the torsion spring lap part 405 overlaps and limits the second torsion spring arm 302. The drive part 202 drags the first torsion spring arm 301 to rotate synchronously. At this time, since the first displacement member 402a abuts against the first limiting member 500a, the first torsion spring arm 301 and the second torsion spring arm 302 are relatively far apart. The rotation of the drive disc 2 increases the elastic potential energy of the energy storage spring. After the drive disc 2 compresses the first displacement member 402a and the second limiting member 500a through the rotation dead point, the rotating seat can rotate freely. At this time, the potential energy of the energy storage spring is converted into torsion spring energy. The overlapping part 405 drives the rotating seat 4 to rotate rapidly, completing the gear switching of the rotary switch along the first direction; when the rotary switch switches to the return direction in the second direction (counterclockwise), the drive disk 2 first drives the second torsion spring arm 302 to open along the second direction, the first torsion spring arm 301 is limited by the torsion spring overlapping part 405, realizing the energy storage spring to store energy, after the second displacement member 402b and the second limiting member 500b pass the rotation dead point, the energy storage spring releases energy to drive the rotating seat 4 to rotate along the second direction (counterclockwise), completing the gear switching of the rotary switch in the return direction.

[0078] Preferably, the torsion spring overlapping part 405 is a torsion spring overlapping boss provided on the inner surface of the rotary seat 4. The torsion spring overlapping boss and the displacement opening 402c are arranged opposite to each other at both ends of the radial direction of the rotary seat 4. During the process of the energy storage spring being abutted by the torsion spring overlapping boss, the energy storage spring can press the first displacement member 402a or the second displacement member 402b against the inner wall surface of the rotary seat cavity through the limiting post 404, thereby ensuring the stability of the overlapping structure between the first displacement member 402a and the first limiting member 500a, or the second displacement member 402b and the second limiting member 500b, and improving the safety of gear switching.

[0079] It should be noted that the torsion spring overlap 405 and the displacement opening 402c are located at both ends of the radial direction of the rotary seat 4. The preferred structure is that the center surfaces of the center positions of the torsion spring overlap 405 and the displacement opening 402c are distributed at approximately 180° along the circumference of the rotary seat 4.

[0080] The rotary seat 4 rotates in the first direction. The first displacement member 402a, in cooperation with the first limiting member 500a, is driven to rotate by the energy released by the energy storage torsion spring. After the first displacement member latching surface 422a of the first displacement member 402a collides with the second limiting member 500b, the rotary seat 4 stops rotating. Correspondingly, the rotary seat 4 rotates in the second direction. The second displacement member 402b, in cooperation with the second limiting member 500b, is driven to rotate by the energy released by the energy storage torsion spring until the second displacement member latching surface 422b of the second displacement member 402b collides with the first limiting member 500a, at which point the rotary seat 4 stops rotating. That is, regardless of whether the rotary seat 4 rotates forward or backward, if it is not constrained, it can only stop rotating by the collision between the displacement member and the limiting member due to rotational inertia. This can easily cause damage to the displacement member and the limiting member and may also affect the safety of the switch position switching.

[0081] like Figure 11 and Figure 12 As shown, Figure 11 A cross-sectional view of the return ramp structure of the second limiting member for displaying the rotary table; Figure 12 for Figure 1 Schematic diagram of the inner side structure of the middle cover plate.

[0082] In this embodiment, a stop 406 is provided on the inner ring of the rotating seat 4 at the displacement opening 402c, and a first cover plate stop 101 and a second cover plate stop 102 are arranged protruding on the inner side of the cover plate 1.

[0083] Along the rotation direction of the rotary seat 4, the stop part 406 has a first stop end face that contacts and engages with the first cover plate stop member 101, and the stop part 406 has a second stop end face that contacts and engages with the second cover plate stop member 102.

[0084] like Figure 9 As shown in position A2, when the rotary seat 4 rotates in the first direction, the second displacement member 402b and the second limiting member 500b slide relative to each other, and the second limiting member 500b falls into the displacement opening 402c.

[0085] Subsequently, as Figure 10 As shown in position A3, the stop 406 contacts and engages with the second cover plate stop 102, and a swing gap 407 is reserved between the second limiting member 500b and the first displacement member 402a. Similarly, when the rotary seat 4 rotates in the second direction, the first displacement member 402a and the first limiting member 500a slide relative to each other until the first limiting member 500a falls into the displacement opening 402c, at which point the stop 406 contacts and engages with the first cover plate stop 101, and a swing gap is also reserved between the first limiting member 50a and the second displacement member 402b. By absorbing the rotational energy of the rotary seat 4 through the impact contact between the stop part 406 and the first cover plate stop 101 or the second cover plate stop 102, the rotary seat 4 can be stopped from rotating. This avoids hard impact between the displacement member and the limiting member, so that the rotation structure of the rotary seat is realized by the displacement member on the rotary seat and the upper limit member of the base, and the stopping structure is realized by the stop part on the rotary seat and the cover plate stop on the cover plate, thus improving the overall structural stability.

[0086] Based on the operating mechanism provided in the above embodiments, the present invention also provides a rotary switch, including a cover plate and a base, and a drive plate and a rotating base arranged between the two. The drive plate drives the rotating base to rotate through an energy storage device to complete the gear switching. An operating mechanism is arranged between the drive plate and the rotating base of the rotary switch. The operating mechanism is the operating mechanism provided in the above embodiments for switching the gears of the rotary switch.
