Abstract
Description
Technical Field
[0001] This application relates to the field of low-voltage electrical technology, and more specifically, to a novel rotary switch operating mechanism. Background Technology
[0002] With technological advancements, especially in photovoltaic systems, photovoltaic DC switches are used in inverters to control the operating status of multiple core components. The reliability of photovoltaic DC switches is crucial not only for the smooth operation of the entire photovoltaic system but also for the stable development of the photovoltaic industry.
[0003] The photovoltaic DC switch includes an operating mechanism and a switch body. The rotation of the operating mechanism drives the moving contact and stationary contact inside the switch body to connect and disconnect.
[0004] On the one hand, existing switch operating mechanisms generally adopt a locking method with elastic deformation structure to achieve contact and separation between the locking element and the locked element, so that the locked element is in a locked or unlocked state. The locking method with elastic deformation structure will cause repeated deformation of the locking structure and subject it to large impact loads during switch operation, which can easily lead to plastic deformation or fracture. This will not only reduce the safety and stability of the switch, but also shorten the service life of the switch.
[0005] On the other hand, in order to reduce the deformation of the elastic locking structure, the locking amount of the locking structure in the existing switch operating mechanism is relatively small. After repeated use, the locking structure will wear down, resulting in a further reduction in the locking amount. This leads to a series of problems such as premature unlocking of the locking structure, which ultimately causes the locking function to fail. The normal opening and closing function of the mechanism will also be affected. This situation will not only shorten the service life of the switch, but also reduce the safety and stability of the switch.
[0006] The information disclosed in the background section of this invention is intended only to enhance the understanding of the overall background of the invention and should not be construed as an admission or in any way implying that such information constitutes prior art known to those skilled in the art. Summary of the Invention
[0007] The purpose of this invention is to provide a rotary switch operating mechanism that adopts a large locking structure, which can overcome the defects of the existing technology where the elastic deformation locking method is prone to plastic deformation or fracture due to repeated deformation and large impact loads, and overcome the defects of reduced reliability and durability due to small locking amount, so that it can still maintain a stable working state under frequent operation.

[0018] In the above-mentioned rotary switch operating mechanism, preferably, the groove height of the opening limit groove (33) and the closing limit groove is more than 4 / 5 of the axial height of the rotating wheel, thereby forming a large locking amount with the cooperation of the opening protrusion and the closing protrusion respectively.

[0021] The arc-shaped range of the protruding structure is the tripping range of the trigger mechanism when it opens or closes the circuit breaker;
[0022] The transition point between the concave curve and the convex curve is the trigger point for tripping and the energy release point of the energy storage element.
[0023] In the above-mentioned rotary switch operating mechanism, preferably, the right locking member includes a right locking fastener and a right reset member, the right locking fastener includes the opening protrusion, one end of the right reset member abuts against the base and the other end abuts against the right locking fastener; the left locking member includes a left locking fastener and a left reset member, the left locking fastener includes the closing protrusion, one end of the left reset member abuts against the base and the other end abuts against the left locking fastener;
[0024] When the drive disc rotates clockwise, the cam structure pushes the right locking fastener to rotate and compresses the right reset member, causing the opening protrusion to disengage from the opening limit groove.

[0027] The unlocking part of the right locking fastener includes a boss structure located above the opening protrusion. The boss structure has a first protruding edge of the right locking fastener and a second protruding edge of the right locking fastener. The second protruding edge of the right locking fastener slides in cooperation with the cam structure of the drive disk to push the right locking fastener to rotate, so that the opening protrusion disengages from the opening limit groove.
[0028] The left locking fastener also includes a left locking fastener rotating part and a left locking fastener unlocking part. The left locking fastener rotating part includes a left locking fastener lower rotating shaft and a left locking fastener upper rotating shaft that are coaxial. The left locking fastener lower rotating shaft is pivotally installed to the left locking fastener mounting hole of the base, and the left locking fastener upper rotating shaft is pivotally installed to the left locking fastener positioning hole of the top cover.
[0029] The unlocking part of the left locking fastener includes a boss structure located above the closing protrusion.

[0031] In the above-mentioned rotary switch operating mechanism, preferably, the opening limit groove includes an opening support surface and a first limit surface, and the opening protrusion further includes a right lock fastener first locking surface, a right lock fastener second locking surface and a right lock fastener abutment surface. When the opening support surface cooperates with the right lock fastener abutment surface and the right lock fastener second locking surface cooperates with the first limit surface, the clockwise rotation of the rotating wheel can be restricted.
[0032] The closing limit groove includes a closing abutment surface and a second limiting surface. The closing protrusion also includes a first locking surface of the left locking fastener, a second locking surface of the left locking fastener, and a left locking fastener abutment surface. When the closing abutment surface engages with the left locking fastener abutment surface, and the first locking surface of the left locking fastener engages with the second limiting surface, the counterclockwise rotation of the rotating wheel can be restricted.

The first end of the left reset element is placed in the second positioning groove for the left locking element, and the second end of the left reset element is placed in the left reset element mounting hole of the base.
[0035] In the above-mentioned rotary switch operating mechanism, preferably, an energy storage limiting boss is provided on the inner side of the outer periphery of the rotating wheel, and the energy storage element has a first torsion arm and a second torsion arm, which are respectively placed on both sides of the energy storage limiting boss.
[0036] The drive plate has a drive boss, and the first torsion arm and the second torsion arm are respectively placed on both sides of the drive boss, and the drive boss is closer to the rotation axis of the rotating wheel than the energy storage limiting boss.
[0037] In the aforementioned rotary switch operating mechanism, preferably, a first thrust boss and a second thrust boss are further provided on the inner side of the outer periphery of the rotating wheel.
[0038] The driving boss pushes the first torsion arm or the second torsion arm to twist. When the multi-layer moving conductive component inside the rotary switch body connected to the rotating wheel has a large rotational resistance and does not rotate, resulting in the locking component releasing the limiting state of the rotating wheel and the energy storage element releasing the energy to drive the rotating wheel to rotate, the first torsion arm can push the first thrust boss to drive the rotating wheel to rotate clockwise, or the second torsion arm can push the second thrust boss to drive the rotating wheel to rotate counterclockwise, so that the driving component forcibly pushes the rotating wheel to rotate, so that the multi-layer moving conductive component inside the rotary switch body connected to the rotating wheel is forcibly rotated.

[0040] The lower part of the rotating wheel is provided with a limiting boss structure. The outer peripheral surface of the limiting boss structure is provided with a first protrusion and a second protrusion. The first protrusion and the second protrusion are used to cooperate with the first open position stop and the second open position stop respectively, so as to limit the rotating wheel (3) to the open position; or the first protrusion and the second protrusion are used to cooperate with the first closed position stop and the second closed position stop respectively, so as to limit the rotating wheel to the closed position.
[0041] In the above-mentioned rotary switch operating mechanism, preferably, the lower part of the top cover is provided with a first slider and a second slider, and the drive disk has a first arc groove and a second arc groove. The first arc groove and the second arc groove are respectively slidably engaged with the first slider and the second slider, thereby guiding the rotation of the drive disk and limiting its rotation range.
[0042] In the above-mentioned rotary switch operating mechanism, preferably, the lower part of the rotating wheel is provided with a connecting hole, which is used to connect the moving conductive component structure of the rotary switch.
[0043] With the above structure, the rotary switch operating mechanism according to the present invention, due to the use of a non-elastic deformation structure locking method, achieves contact and disengagement between the locking element and the locked element by driving the rotational movement of the locking element, realizing the locked element in a locked state and an unlocked state. This non-elastic deformation structure locking method can improve the locking strength and stability of the locking structure, and can effectively reduce the impact load on the locking element during the locking process, extend the service life of the photovoltaic DC switch, and improve the safety and stability of the switch.
[0044] Meanwhile, the operating mechanism of the switch adopts a large locking structure, which utilizes the longitudinal (axial) space of the side wall of the locking part of the locked component to greatly increase the locking amount, improve the locking performance of the mechanism, and further enhance the safety and stability of the switch.
[0045] In summary, this patent provides a novel rotary switch operating mechanism that solves the problems existing in the prior art, improves the safety and stability of the switch, and extends its lifespan. This disconnecting switch is suitable for inverters in photovoltaic systems and has positive significance for the stable development of the photovoltaic industry.

[0156] It should be understood that the accompanying drawings are not necessarily drawn to scale, and illustrate various features of the basic principles of the invention in a simplified manner. Specific design features of the invention disclosed herein, including, for example, specific dimensions, orientations, positioning, and shapes, will be determined in part by the application and environment of use for a particular purpose.
[0157] In these accompanying drawings, and in the multiple figures throughout the drawings, reference numerals refer to the same or equivalent parts of the invention. Detailed Implementation
[0158] Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings. These exemplary embodiments are examples and can be implemented in various different forms by those skilled in the art. Therefore, the present invention is not limited to the exemplary embodiments described herein.
[0159] Figure 1 An exploded perspective view of the switch operating mechanism according to the present invention is shown.
[0160] like Figure 1 As shown, the rotary switch operating mechanism of the present invention includes a base 1 having a receiving cavity, a top cover 2 covering the receiving cavity, a rotating wheel 3 rotatably disposed within the receiving cavity, a drive assembly 4, and a locking assembly 5, and an energy storage element 6 disposed within the rotating wheel 3 and connected between the rotating wheel 3 and the drive assembly 4. The drive assembly 4 includes a drive disk 41 and a mechanism shaft 42 connected to and capable of driving the drive disk 4 to rotate. The locking assembly 5 includes a right locking member 51 and a left locking member 52. The right locking member includes a right latch 511 and a right reset member 512. The left locking member includes a left latch 521 and a left reset member 522.
[0161] The left locking member 52 is used to prevent the rotating wheel 3 from rotating counterclockwise, thereby limiting the rotating wheel 3 to the closed position. The right locking member 51 is used to prevent the rotating wheel 3 from rotating clockwise, thereby limiting the rotating wheel 3 to the open position.
[0162] The right locking fastener and the left locking fastener are symmetrically positioned and have the same structure or symmetrical structures. The right locking member 51 and the left locking member 52 are symmetrically positioned and have the same structure or symmetrical structures. In the relevant views, the right locking member 51 and the left locking member 52 are shown as two components with the same structure but symmetrically positioned.
[0163] Figure 2 A cross-sectional view of the switch operating mechanism according to the present invention is shown, which illustrates the internal assembly structure of the switch operating mechanism.
[0164] Figure 3 A schematic diagram of the base of the switch operating mechanism according to the present invention is shown.
[0165] like Figure 3As shown, the base 1 is provided with a rotating wheel mounting hole 11 for accommodating the rotating wheel 3. The rotating wheel mounting hole 11 is provided with a right locking fastener mounting hole 121, a left locking fastener mounting hole 122, a right reset fastener mounting cavity 131, and a left reset fastener mounting cavity 132 around its perimeter.
[0166] A circuit breaker limiting structure 14 is provided at the bottom of the rotating wheel mounting hole 11. When the energy storage element 6 releases energy and drives the rotating wheel 3 to rotate, the rotating wheel 3 stops at the open position or the closed position. The circuit breaker limiting structure 14 includes two blocks that are protruding inward and arranged opposite each other. The sides of the two blocks respectively form a first open position stop 141, a second open position stop 142, a first closed position stop 143, and a second closed position stop 144.
[0167] like Figure 2 , Figure 3 As shown, the base 1 is also provided with a first oil delivery groove 151 and a second oil delivery groove 152 for placing excess lubricating oil to prevent or reduce excess lubricating oil from entering the switch body from the opening and closing limit structure 14.
[0168] Figure 4A A three-dimensional schematic diagram of the upper side of the top cover of the switch operating mechanism according to the present invention is shown. Figure 4B A perspective view of the lower side of the top cover of the switch operating mechanism according to the present invention is shown.
[0169] like Figure 4A , 4B As shown, the top cover 2 is provided with a gland 21 for mounting a rotary switch to the inverter housing. The center of the gland 21 is provided with a mounting hole 211 for mounting the shaft 42 of the mechanism.
[0170] The gland 21 has a threaded structure 212 on its outer side, which engages with a nut to mount the rotary switch onto the inverter housing. It should be noted that the threaded structure 212 in the attached diagram is merely an example. In fact, there are many different structures for mounting and fixing the switch; any structure that can secure the switch to the housing is feasible.
[0171] The lower part of the top cover 2 is provided with multiple reinforcing ribs 22, and also has a protruding slider. The slider includes a first slider 231 and a second slider 232, which are used to guide the rotation of the drive disk 41 and limit its rotation range, thereby limiting its rotation to stay in the open or closed position.
[0172] The lower part of the top cover 2 is provided with a right locking fastener positioning hole 241 and a left locking fastener positioning hole 242. The lower part of the top cover 2 is also provided with a right reset member limiting boss 251 and a left reset member limiting boss 252, which are used to fix the end of the right reset member and the end of the left reset member, respectively.
[0173] Figure 5AA three-dimensional schematic diagram of the upper side of the rotating wheel of the switch operating mechanism according to the present invention is shown. Figure 5B A perspective view of the lower side of the rotating wheel of the switch operating mechanism according to the present invention is shown.
[0174] like Figure 5A , Figure 5B As shown, the rotating wheel 3 has a circular structure and is equipped with a limiting cam 31 and an outer periphery. The outer circular surface of the limiting cam 31 is used to limit the position of the energy storage element 6, acting as a positioning guide rod. The center of the limiting cam 31 is provided with a rotating wheel shaft hole 311 for coaxial cooperation with the mechanism shaft 42.
[0175] An energy storage limiting boss 32 is provided on the inner side of the outer periphery of the rotating wheel 3. The energy storage limiting boss 32 includes a left limiting surface 321 and a right limiting surface 322, which are used to limit the positions of the second torsion arm 62 and the first torsion arm 61 of the energy storage element 6, respectively. During the energy storage process of the energy storage element, the left limiting surface 321 or the right limiting surface 322 fixes the position of one of the second torsion arm 62 and the first torsion arm 61.
[0176] The rotating wheel 3 is provided with a tripping limit groove 33 and a closing limit groove 34.
[0177] The tripping limit groove 33 includes a tripping abutment surface 331 and a first limiting surface 332. The tripping abutment surface 331 is used to cooperate with the abutment surface 51131 of the right locking member to limit the clockwise rotation of the rotating wheel 3. The first limiting surface 332 is used to limit the counterclockwise rotation of the right locking member.
[0178] The closing limit groove 34 includes a closing abutment surface 341 and a second limiting surface 342. The closing limit groove 33 and the opening limit groove 34 are arranged symmetrically. The closing abutment surface 341 is used to cooperate with the abutment surface 52131 of the left locking member to limit the counterclockwise rotation of the rotating wheel 3. The second limiting surface 342 is used to limit the clockwise rotation of the right locking member.
[0179] The rotating wheel 3 is also provided with a first thrust boss 351 and a second thrust boss 352, which are used to push the rotating wheel 3 to rotate.
[0180] After the drive disc 41 has pushed open the locking mechanism and the locking mechanism has unlocked the rotating wheel 3, if there is significant friction within the main body structure, the energy released by the energy storage element 6 cannot drive the rotating wheel 3 to rotate, thus preventing the connection or disconnection of the moving and stationary contacts within the main body. In this situation, the rotation of the drive assembly 4 pushes the energy storage element 6 to twist, allowing the first torsion arm 61 of the energy storage element to contact the first thrust boss 351, or the second torsion arm 62 to contact the second thrust boss 352, thereby creating a rigid connection. Therefore, by rotating the drive assembly, the rotating wheel 3 is directly driven to rotate, thus forcibly achieving the connection or disconnection of the moving and stationary contacts.
[0181] The rotating wheel 3 has a limiting boss structure 36 at its lower part. The rotating wheel 3 also has a connecting hole 361 at its lower part for connecting to the moving conductive component of a photovoltaic DC switch. In the example shown in the accompanying drawings of the present invention, the connecting hole 361 is located at the center of the limiting boss structure 36.
[0182] The outer peripheral surface of the limiting boss structure 36 is provided with a first protrusion 3621 and a second protrusion 3622. The first protrusion 3621 and the second protrusion 3622 are used to cooperate with the first open position stop 141 and the second open position stop 142 of the rotating wheel opening and closing limiting structure 14, respectively, so as to limit the rotating wheel 3 in the open position; or the first protrusion 3621 and the second protrusion 3622 are used to cooperate with the first closing position stop 143 and the second closing position stop 144, respectively, so as to limit the rotating wheel 3 in the closed position.
[0183] Figure 6A A top perspective view of the drive assembly of the switch operating mechanism according to the present invention is shown. Figure 6B A lower perspective view of the drive assembly of the switch operating mechanism according to the present invention is shown.
[0184] like Figure 6A , Figure 6B As shown, the drive assembly 4 includes a drive disk 41 and a mechanism shaft 42. The drive disk 41 is provided with a first arc-shaped groove 4111 and a second arc-shaped groove 4112, which are used to slide in cooperation with the first slider 231 and the second slider 232 on the top cover 2, thereby guiding the rotation of the drive disk and limiting the rotation range of the drive disk 41.
[0185] Meanwhile, the drive disk 41 is also provided with a shaft pin groove 412 for engaging with the pin 421 on the mechanism shaft 42. A sealing ring 422 is provided in the middle of the mechanism shaft 42 to prevent impurities from entering the mechanism. The mechanism shaft 42 passes through the central hole of the drive disk 41 and protrudes from the lower part of the drive disk 41.
[0186] The outer periphery of the drive disk 41 is a cam structure with symmetrically arranged concave and convex curves. The arc range of the concave structure controls the working deformation angle and energy storage stroke of the energy storage element 6; within the arc range of the concave structure, the rotating wheel 3 is in a stationary state; the arc range of the convex structure is the tripping range of the trigger mechanism for opening or closing; the transition point between the concave curve and the convex curve is the triggering tripping point and the energy storage release point of the energy storage element.
[0187] Specifically, the cam structure includes a first inclined surface 4151, an arc surface 4152, and a second inclined surface 4153. During the opening or closing process, the cam structure cooperates with the right locking element 511 and the left locking element 521. When the drive disk 41 is rotated, the cam structure can push the right locking element 511 or the left locking element 521 to rotate, thereby realizing the unlocking action.
[0188] The lower part of the drive disk 41 is provided with a drive boss 413, which is used to drive the torsion of the energy storage element 6 to store energy. The drive boss 413 structure includes a semi-circular boss 4131 and a reinforcing rib structure 4132, which makes the drive boss 413 stronger to withstand the large load generated by the energy storage element 6 during operation.
[0189] Figure 7A A schematic diagram of the right locking fastener and the left locking fastener of the switch operating mechanism according to the present invention is shown. Figure 7B A schematic diagram of the right locking fastener and the left locking fastener of the switch operating mechanism according to the present invention is shown.
[0190] like Figure 7A , Figure 7B As shown, the right locking fastener and the left locking fastener have the same structure.
[0191] like Figure 7A , Figure 7B As shown, the right locking fastener 511 includes a rotating part, a tripping protrusion, and an unlocking part. The rotating part of the right locking fastener 511 includes a lower rotating shaft 5111 and an upper rotating shaft 5112. The lower rotating shaft 5111 is used to mate with the base, and the upper rotating shaft 5112 is used to mate with the top cover, thereby defining the rotation axis of the right locking fastener 511.
[0192] The opening protrusion of the right locking fastener 511 includes a right locking fastener abutment surface 51131. The right locking fastener abutment surface 51131 engages with the opening limiting groove 33 on the rotating wheel 3, thereby limiting the clockwise rotation of the rotating wheel 3. Preferably, the groove height of the opening limiting groove 33 is more than 4 / 5 of the axial height of the rotating wheel 3, thereby forming a large locking amount with the engagement of the opening protrusion.
[0193] The opening protrusion of the right locking fastener 511 also includes a first locking surface 5113 and a second locking surface 5114 of the right locking fastener, wherein the second locking surface 5114 of the right locking fastener is used to cooperate with the first limiting surface 332 of the rotating wheel 3 to limit its rotation.
[0194] The opening protrusion of the right locking fastener 511 also includes a first positioning groove 51133 and a second positioning groove 51134. The first positioning groove 51133 is used to accommodate the first end 5121 of the right reset fastener 512. The second end 5122 of the right reset fastener 512 is placed in the right reset fastener mounting cavity 131 on the base 1.
[0195] The opening protrusion of the right locking fastener 511 also includes a first right locking fastener spindle 51135 and a second right locking fastener spindle 51136. The first right locking fastener spindle 51135 is located in the first right locking fastener positioning groove 51133, and the second right locking fastener spindle 51136 is located in the second right locking fastener positioning groove 51134. The first right locking fastener spindle 51135 makes the positioning of the right reset member 512 in the first right locking fastener positioning groove 51133 more stable.
[0196] The unlocking part of the right locking fastener 511 includes a boss structure disposed on the upper part of the tripping protrusion. The boss structure has a first protruding edge 51132 and a second protruding edge 51132' of the right locking fastener. The first protruding edge 51132 and the second protruding edge 51132' of the right locking fastener protrude from the outer side of the tripping protrusion.
[0197] The unlocking part of the right locking fastener 511 cooperates with the outer circular cam structure of the drive disk 41. The rotation of the drive disk 41 pushes the right locking fastener 511 to rotate, causing the opening protrusion to disengage from the opening limit groove, thereby realizing the unlocking of the rotating wheel (3).
[0198] Although the right and left locking fasteners have identical structures, the right locking member 51 and the left locking member 52 are symmetrically arranged with respect to the rotating wheel 3, resulting in a different mating direction between the left locking member 521 and the left reset member 522 compared to the right locking member 51.
[0199] like Figure 7A , Figure 7B As shown, the left locking fastener 521 includes a rotating part, a closing protrusion, and an unlocking part. The rotating part of the left locking fastener 521 includes a lower rotating shaft 5211 and an upper rotating shaft 5212. The lower rotating shaft 5211 is used to cooperate with the base, and the upper rotating shaft 5212 is used to cooperate with the top cover, thereby defining the rotation axis of the left locking fastener 521.
[0200] The closing protrusion of the left locking fastener 521 includes a left locking fastener abutment surface 52131. The left locking fastener abutment surface 52131 engages with the closing limiting groove 34 on the rotating wheel 3, thereby restricting the counterclockwise rotation of the rotating wheel 3. Preferably, the groove height of the closing limiting groove 34 is more than 4 / 5 of the axial height of the rotating wheel 3, thereby forming a large locking amount with the engagement of the closing protrusion.
[0201] The closing protrusion of the left locking fastener 521 also includes a first locking surface 5213 and a second locking surface (5214) of the left locking fastener, wherein the first locking surface (5213) of the left locking fastener is used to cooperate with the second limiting surface 342 of the rotating wheel 3 to limit its rotation.
[0202] The closing protrusion of the left locking fastener 521 also includes a first positioning groove 52133 and a second positioning groove 52134. The second positioning groove 52134 is used to accommodate the first end 5221 of the left reset fastener 522. The second end 5222 of the left reset fastener 522 is placed in the left reset fastener mounting cavity 132 on the base 1.
[0203] The closing protrusion of the left locking fastener 521 also includes a first left locking fastener spindle 52135 and a second left locking fastener spindle 52136. The first left locking fastener spindle 52135 is located in the first left locking fastener positioning groove 52133, and the second left locking fastener spindle 52136 is located in the second left locking fastener positioning groove 52134. The second left locking fastener spindle 52136 makes the positioning of the left reset member 522 in the second left locking fastener positioning groove 52134 more stable.
[0204] The unlocking part of the left locking fastener 521 includes a boss structure disposed on the upper part of the closing protrusion. The boss structure has a first protruding edge 52132 and a second protruding edge 52132' of the left locking fastener. The first protruding edge 52132 and the second protruding edge 52132' of the left locking fastener protrude from the outer side of the protrusion. The unlocking part of the left locking fastener 521 cooperates with the cam structure on the outer circular edge of the drive disk 41. The rotation of the drive disk 41 pushes the left locking fastener 521 to rotate, causing the closing protrusion to disengage from the closing limit groove, thereby unlocking the rotating wheel (3).
[0205] Figure 8 A schematic diagram of the right reset member and left reset member of the switch operating mechanism according to the present invention is shown.
[0206] like Figure 8 As shown, the right reset member 512 and the left reset member 522 have the same structure.
[0207] The right reset member 512 includes a first end 5121 and a second end 5122. The first end 5121 is used to be placed in the first positioning groove 51133 of the right locking member. The second end 5122 is used to be placed in the right reset member mounting cavity 131 on the base 1.
[0208] The left reset member 522 includes a first end 5221 and a second end 5222. The first end 5221 is used to be placed in the second positioning groove 52134 of the left locking member. The second end 5222 is used to be placed in the left reset member mounting cavity 132 of the base 1.
[0209] Figure 9 A schematic diagram of the energy storage element of the switching operation mechanism according to the present invention is shown.
[0210] like Figure 9 As shown, the energy storage element 6 has a first torsion arm 61 and a second torsion arm 62.
[0211] The energy storage element 6 is disposed inside the drive wheel 3, and the energy storage limiting boss 32 of the drive wheel 3 is disposed between the first torsion arm 61 and the second torsion arm 62. The drive boss 413 of the drive disc 41 is disposed between the first torsion arm 61 and the second torsion arm 62 of the energy storage element 6.
[0212] The drive boss 413 of the drive disc 41 is located on the side of the energy storage limiting boss 32 of the drive wheel 3, close to the center of the drive wheel.
[0213] When the rotating wheel 3 is locked, rotating the drive disk 41 can drive the first torsion arm 61 or the second torsion arm 62 of the energy storage element 6 to rotate and store energy. After unlocking the rotating wheel 3, the energy storage element 6 releases energy and drives the rotating wheel 3 and the drive disk 41 to rotate in the same direction.
[0214] The drive boss 413 can push the first torsion arm 61 or the second torsion arm 62 to rotate. When the multi-layer (multi-stage) moving conductive components inside the rotary switch body connected to the rotating wheel 3 have high rotational resistance and do not rotate, causing the rotating wheel 3 to not rotate after the opening or closing limit unlocking, the first torsion arm 61 can push the first thrust boss 351 or the second torsion arm 62 can push the second thrust boss 352, driving the rotating wheel 3 to rotate, so that the drive component 4 forcibly pushes the rotating wheel 3 to rotate, and so that the moving conductive components inside the rotary switch body connected to the rotating wheel 3 are forced to rotate.
[0215] The process of switching the rotary switch operating mechanism from the open state to the closed state is as follows: :
[0216] When the opening protrusion of the right locking member 51 is inserted into the opening limit groove 33 of the rotating wheel 3, and the closing protrusion of the left locking member 52 is disengaged from the closing limit groove 34 of the rotating wheel 3, the rotating wheel 3 is in the opening position.
[0217] In the open position, under the action of the right reset member 512, the locking surface 5113 of the right locking member 511 is embedded into the open limit groove 33 of the rotating wheel 3, thereby preventing the rotating wheel 3 from rotating clockwise, so that the right locking member 512 locks the rotating wheel 3 in the open position; at the same time, under the push of the cam structure of the drive disk 41 of the drive assembly 4, the locking surface 5213 of the left locking member 521 disengages from the closing limit groove 34 of the rotating wheel 3, so that the left locking member 521 does not lock the rotating wheel 3.
[0218] When the operating mechanism switches from the open state to the closed state, the drive assembly 4 is driven by a driving force and rotates in the first direction (clockwise), driving the energy storage element 6 to twist and store energy. After the drive assembly 4 rotates, it disengages from the left locking fastener 521. The left locking fastener 521 is then driven by the left reset member 522 to rotate and contact the outer surface of the rotating wheel 3.
[0219] When the drive assembly 4 rotates to a certain angle, the drive disk 41 contacts the right locking fastener 511. The drive disk 41 continues to rotate and pushes the right locking fastener 511 to rotate. The right locking fastener 511 compresses the right reset member 512 to store energy.
[0220] After the right locking fastener 511 rotates to a certain angle, it disengages from the rotating wheel 3 and releases the locking state of the rotating wheel 3.
[0221] When the right locking fastener 511 is released from the lock on the rotating wheel 3, the energy stored in the energy storage element 6 is released, and the rotating wheel 3 is driven to rotate in the first direction (clockwise direction).
[0222] The rotation of the rotating wheel 3 drives the moving conductive component inside the switch body to rotate, causing the moving contact and the stationary contact to switch from the open state to the closed state.
[0223] When the energy stored in the energy storage element 6 is released, after the driving rotating wheel 3 rotates at a certain angle, the rotating wheel 3 stops rotating due to the restriction of the closing limit structure of the base 1. The left locking fastener 521 rotates under the action of the energy released by the left reset member 522. The left locking fastener 521 cooperates with the rotating wheel 3, and the closing protrusion is embedded in the closing limit groove 34 of the rotating wheel 3 to lock the rotating wheel 3, so that the rotating wheel 3 is in the closed locked state.
[0224] In other words, the drive assembly 4 rotates (clockwise), driving the energy storage element 6 to rotate and store energy. When the drive assembly 4 pushes the opening protrusion of the right locking member 51 out of the opening limit groove 33 of the rotating wheel 3, the energy storage element 6 releases energy, driving the rotating wheel 3 to rotate from the opening position to the closing position. At the same time, the closing protrusion of the left locking member 52 engages with the closing limit groove 34 of the rotating wheel 3. At this time, the operating mechanism is in the closing state, and the moving contact and stationary contact in the switch body switch from the open state to the closed state.
[0225] Conversely, the process of switching the rotary switch operating mechanism from the closed state to the open state is as follows:
[0226] When the closing protrusion of the left locking member 52 is inserted into the closing limit groove 34 of the rotating wheel 3, and the opening protrusion of the right locking member 51 is disengaged from the opening limit groove 33 of the rotating wheel 3, the rotating wheel 3 is in the closing position.
[0227] In the closed state, under the pushing action of the cam structure of the drive disk 41 of the drive assembly 4, the locking surface 5113 of the right locking member 511 disengages from the opening limit groove 33 of the rotating wheel 3, thereby releasing the rotation of the rotating wheel 3 and releasing the locking state of the rotating wheel 3. At the same time, the right locking member 511 compresses the right reset member 512 to store energy, and the left locking member 521 cooperates with the rotating wheel 3 to form a locked state under the action of the left reset member 522.
[0228] When the operating mechanism switches from the closed state to the open state, the drive assembly 4 is driven to rotate in the second direction (opposite to the first direction), and drives the energy storage element 6 to twist and store energy. After the drive assembly 4 rotates, it disengages from the right locking member 511. The right locking member 511 rotates under the energy release drive of the right reset member 512, thereby contacting the outer surface of the rotating wheel 3.
[0229] After the drive assembly 4 rotates to a certain angle, the drive disk 41 contacts the left locking fastener 521. The drive disk 41 continues to rotate and pushes the left locking fastener 521 to rotate, causing the left locking fastener 521 to compress the left reset member 522 and store energy.
[0230] After the left locking fastener 521 rotates to a certain angle, it disengages from the rotating wheel 3 and releases the locking state of the rotating wheel 3.
[0231] When the lock between the left locking element 521 and the rotating wheel 3 is released, the energy stored in the energy storage element 6 is released, thereby driving the rotating wheel 3 to rotate in the second direction (counterclockwise).
[0232] The rotation of the rotating wheel 3 drives the moving conductive component inside the switch body to rotate, causing the moving contact and the stationary contact to switch from the connected state to the disconnected state.
[0233] When the energy storage element 6 releases its stored energy, after the driving rotating wheel 3 rotates at a certain angle, the rotating wheel 3 stops rotating under the restriction of the tripping limit structure of the base 1. The right locking member 511 rotates under the energy release action of the right reset member 512. The right locking member 511 cooperates with the rotating wheel 3, and the tripping protrusion is embedded in the tripping limit groove 33 of the rotating wheel 3 to lock the rotating wheel 3, so that the rotating wheel 3 is in the tripping locked state.
[0234] In other words, the drive assembly 4 rotates (counterclockwise), thereby driving the energy storage element 6 to rotate and store energy. When the drive assembly 4 pushes the closing protrusion of the left locking member 52 out of the closing limit groove 34 of the rotating wheel 3, the energy storage element 6 releases energy, driving the rotating wheel 3 to rotate from the closed position to the open position. At the same time, the opening protrusion of the right locking member 51 engages with the opening limit groove 33 of the rotating wheel 3. At this time, the operating mechanism is in the open state, and the moving contact and stationary contact in the switch body switch from the closed state to the open state.
[0235] Therefore, the right locking member 51 and the left locking member 52 of the locking assembly 5 are always in different states. That is, one of them is locked to the rotating wheel 3, while the other is unlocked. During the opening or closing process of the driving operating mechanism, one of them switches from the locked state to the unlocked state, and the other switches from the unlocked state to the locked state.
[0236] The locking process described above will be further described as follows:
[0237] Taking the right locking member as an example, the locking process of the locking structure of the locking member is summarized below. The locking process of the left locking member is the same. The locking relationship between the right locking member 51 and the rotating wheel 3 is as follows: The right locking latch 511 of the right locking member 51 rotates under the action of the right reset member 512. The opening protrusion of the right locking latch 511 slides into the opening limiting groove 33 of the rotating wheel 3. The low holding surface of the protrusion of the right locking latch 511 cooperates with the limiting surface of the rotating wheel 3, thereby forming a large latch structure. Through the relative sliding between the bottom holding surface and the limiting surface, the locking assembly 5 and the drive wheel 3 are locked or unlocked. The large latch structure can achieve a larger locking amount, improving the locking performance of the mechanism.

When the multi-layer dynamic conductive component inside the rotary switch body connected to the rotating wheel (3) has a large rotational resistance and does not rotate, the locking component (5) releases the limiting state of the rotating wheel (3) and the energy storage element (6) cannot drive the rotating wheel (3) to rotate. In this case, the first torsion arm (61) can push the first thrust boss (351) to drive the rotating wheel (3) to rotate clockwise, or the second torsion arm (62) can push the second thrust boss (352) to drive the rotating wheel (3) to rotate counterclockwise, so that the drive component (4) forces the rotating wheel (3) to rotate, so that the multi-layer dynamic conductive component inside the rotary switch body connected to the rotating wheel (3) is forced to rotate.
7. The rotary switch operating mechanism according to claim 1, wherein, The base (1) is provided with a rotating wheel mounting hole (11) for accommodating the rotating wheel (3). The bottom of the rotating wheel mounting hole (11) is provided with a circuit breaker limiting structure (14). The circuit breaker limiting structure (14) includes two blocks that are protruding inward and arranged opposite to each other. The sides of the two blocks respectively form a first open position stop edge (141), a second open position stop edge (142), a first closed position stop edge (143), and a second closed position stop edge (144). The lower part of the rotating wheel (3) is provided with a limiting boss structure (36). The outer peripheral surface of the limiting boss structure (36) is provided with a first protrusion (3621) and a second protrusion (3622). The first protrusion (3621) and the second protrusion (3622) are used to cooperate with the first open position stop (141) and the second open position stop (142) respectively, so as to limit the rotating wheel (3) in the open position; or the first protrusion (3621) and the second protrusion (3622) are used to cooperate with the first closed position stop (143) and the second closed position stop (144) respectively, so as to limit the rotating wheel (3) in the closed position.
