Description

Technical Field

[0001] The utility model relates to the field of low-voltage electrical appliances, in particular to an energy storage transmission component. Background Art

[0002] Switching electrical appliances are used to close and open circuits, and include an operating mechanism and at least one switch unit. The operating mechanism is connected to the moving contact mechanism of the switch unit, driving the moving contact mechanism to rotate and close and disconnect with the corresponding static contact. In its operating mechanism, the energy storage spring is fixed at one end and the other end is a movable end connected to the main shaft to complete energy storage and energy release. When the energy storage spring releases energy, it drives the main shaft to rotate and the main shaft drives the moving contact mechanism to rotate through the output shaft. This method results in a limited rotation angle of the output shaft, resulting in a small opening distance between the moving contact mechanism and the static contact after disconnection, which affects the improvement of the electrical performance of the switch device. When assembling the operating mechanism, each component needs to be assembled separately, which is cumbersome and difficult to assemble. In addition, the assembly reliability of the energy storage spring and the main shaft is poor, and it may be detached during the operation, affecting the reliability of the operating mechanism.

[0057] The following is a further description of the specific implementation of the switch device of the present utility model in conjunction with the embodiments given in the accompanying drawings. The switch device of the present utility model is not limited to the description of the following embodiments.

[0058] like Figure 1-17 As shown, it is an embodiment of the switch electrical appliance of the utility model. The electrical switch of this embodiment is preferably an isolating switch, which includes an operating mechanism o and at least one group of switch units p. The switch unit p includes a unit shell 9 and a contact system arranged in the unit shell 9. The contact system includes a moving contact mechanism m and a static contact used in conjunction with each other. The moving contact mechanism m is rotatably arranged. The operating mechanism o is connected to the moving contact mechanism m of the switch unit p in a transmission manner to drive the contact systems of each switch unit p to close and open synchronously, that is, to drive the isolating switch to close and open. The operating mechanism o and the switch unit p are arranged side by side along the rotation axis direction of the moving contact mechanism m. Further, the isolating switch includes multiple groups of switch units p, each of which is arranged side by side along the rotation axis direction of the moving contact mechanism m and is closed and opened synchronously under the drive of the operating mechanism o.

[0059] Specifically, the moving contact mechanism m is rotatably arranged around the axis o2-o2, the operating mechanism o and the switch unit p are arranged side by side along the axis o2-o2, and the switch units p are also arranged side by side along the axis o2-o2.

[0060] like Figure 1-17 The figure shows an embodiment of the operating mechanism o.

[0061] like Figure 1-3As shown in , 5-8, and 16, the operating mechanism o of the first embodiment includes a mechanism housing 1 and an operating shaft 2 and an energy storage transmission assembly a arranged in the mechanism housing 1; the operating shaft 2 is driven by an external force to reciprocate to switch between the opening position and the closing position; the energy storage transmission assembly a includes a connecting rod 5 which reciprocates around the axis o2-o2 to switch between the third position and the fourth position and is used to be connected to the moving contact mechanism m of the switching electrical appliance, an energy storage shaft s which reciprocates around the axis o2-o2 to switch between the first position and the second position, and a spring 6 which is rotationally connected to the connecting rod 5 and the energy storage shaft s at both ends respectively, the connecting rod 5 and the energy storage shaft s are coaxially arranged for rotation, and the energy storage shaft s is driven by the operating shaft 2 to rotate; when the energy storage shaft s switches positions, the energy storage shaft s drives the spring 6 to store energy first and then release energy, the connecting rod 5 remains stationary before the spring 6 starts to release energy, and the spring 6 releases energy to drive the energy storage shaft s and the connecting rod 5 to rotate in opposite directions respectively.

[0062] Specifically, the connecting rod 5 and the energy storage shaft s are coaxially rotatable, and the rotation axes of the two are both axis o2-o2; the connecting rod 5 has two working positions, which are respectively the third position and the fourth position. The connecting rod 5 is rotatable around the axis o2-o2 and switches between the third position and the fourth position by reciprocating rotation. The connecting rod 5 is also used to be connected to the moving contact mechanism m of the switching electrical appliance to drive the moving contact mechanism m to rotate so as to close and disconnect with the corresponding static contact; the energy storage shaft s has two working positions, which are respectively the first position and the second position. The energy storage shaft s is rotatable around the axis o2-o2 and switches between the first position and the second position by reciprocating rotation; the operating shaft 2 is driven by an external force to reciprocate and drive the energy storage shaft s to rotate reciprocatingly, so that the energy storage shaft s switches between its two working positions. When the operating mechanism o performs the opening or closing operation, the operating shaft 2 is driven by an external force (the external force can come from the user's manual operation or from the electric drive mechanism) to move, and at the same time, the operating shaft 2 drives the energy storage shaft s to rotate from one working position to another working position (the energy storage shaft s rotates from the first position to the second position or from the second position to the first position), that is, the operating shaft 2 drives the energy storage shaft s to rotate and switch the working position. During the rotation process of the energy storage shaft s, the spring 6 is first driven to move to the maximum energy storage position (such as Fig.16 (2) of the figure) so that the spring 6 completes the energy storage (as shown in FIG. Fig.16 As shown in parts (1)-(2) of FIG. 5 , during the process of the energy storage shaft s driving the spring 6 to store energy, the end of the spring 6 connected to the energy storage shaft s makes a circular motion around the axis o2-o2, and the end of the spring 6 connected to the connecting rod 5 remains stationary). Then the energy storage shaft s drives the spring 6 to pass the maximum energy storage position, and then the spring 6 starts to release energy. The energy released by the spring 6 drives the energy storage shaft s to continue rotating in the original rotation direction while driving the connecting rod 5 to rotate in the opposite direction to the energy storage shaft s until the energy storage shaft s and the connecting rod 5 complete the position switching (as shown in FIG. 5 ). Fig.16 As shown in parts (2)-(3), during the energy release process of the spring 6, the end of the spring 6 connected to the energy storage shaft s makes a circular motion around the axis o2-o2 along the rotation direction of the energy storage shaft s, and the end of the spring 6 connected to the connecting rod 5 makes a circular motion around the axis o2-o2 along the rotation direction of the connecting rod 5, that is, during the energy release process, both ends of the spring 6 make a circular motion around the axis o2-o2 and the motion directions are opposite); during the time period between the moment when the operating shaft 2 drives the energy storage shaft s to start rotating and the moment when the operating shaft 2 drives the spring 6 to pass the maximum energy storage position through the energy storage shaft s, the connecting rod 5 remains stationary and will not rotate due to the movement of the energy storage shaft s and the spring 6. Furthermore, the opening position, the first position and the third position correspond to each other, and the closing position, the second position and the fourth position correspond to each other, that is: when the operating mechanism o is in the opening state, the operating shaft 2 is in the opening position, the energy storage shaft s is in the first position and the connecting rod 5 is in the third position; when the operating mechanism o is in the closing state, the operating shaft 2 is in the closing position, the energy storage shaft s is in the second position and the connecting rod 5 is in the fourth position; that is to say, the operating shaft 2 is driven by an external force to rotate from the opening position to the closing position, so that the operating mechanism o performs the closing operation and switches from the opening state to the closing state; the operating shaft 2 is driven by an external force to rotate from the closing position to the opening position, so that the operating mechanism o performs the opening operation and switches from the closing state to the opening state.

[0063] Compared with the scheme of the existing operating mechanism in which one end of the energy storage spring is fixed and the other end performs circular motion to store and release energy, the operating mechanism o of this embodiment has both ends of the spring 6 that can move, so that the operating mechanism of this embodiment can achieve a significant increase in the rotation angle of the connecting rod 5 under the condition of a space size similar to that of the existing operating mechanism, thereby greatly improving the final gap (that is, the breaking gap between the moving contact and the static contact) at which the moving contact mechanism connected to the connecting rod 5 is disconnected, thereby greatly improving the breaking performance and electrical performance of the switch electrical appliance using the operating mechanism o of this embodiment, especially for the breaking of large current DC circuits; and the operating mechanism o of this embodiment has a simple structure, a compact layout, and requires less space.

[0064] Further, such as Figure 3 , 6As shown in , 13 and 15, when the spring 6 acts on the energy storage shaft s to establish a first limiting fit with the mechanism housing 1 and keep the energy storage shaft s in the first position, the energy storage shaft s has a tendency to rotate in the second direction under the action of the spring 6; when the spring 6 acts on the energy storage shaft s to establish a second limiting fit with the mechanism housing 1 and keep the energy storage shaft s in the second position, the energy storage shaft s has a tendency to rotate in the first direction under the action of the spring 6; the energy storage shaft s rotates in the first direction (or the second direction) in the first position (or the second position) to switch to the second position When the spring 6 acts on the connecting rod 5 to establish a third limiting fit with the mechanism housing 1 and keep the connecting rod 5 in the third position, the connecting rod 5 has a tendency to rotate in the first direction under the action of the spring 6; when the spring 6 acts on the connecting rod 5 to establish a fourth limiting fit with the mechanism housing 1 and keep the connecting rod 5 in the fourth position, the connecting rod 5 has a tendency to rotate in the second direction under the action of the spring 6; the connecting rod 5 rotates in the second direction (or the first direction) in the third position (or the fourth position) to switch to the fourth position or the third position.

[0065] Specifically, when the energy storage shaft s switches from the first position to the second position, the energy storage shaft s rotates along the first direction, the energy storage shaft s drives the spring 6 to move to the maximum energy storage position and exceeds the maximum energy storage position, and the spring 6 releases energy and drives the energy storage shaft s to continue to rotate toward the second position until the energy storage shaft s and the mechanism housing 1 establish a second limit fit and limit the energy storage shaft s to the second position; when the energy storage shaft switches from the second position to the first position, the energy storage shaft s rotates along the second direction, the energy storage shaft s drives the spring 6 to move to the maximum energy storage position and exceeds the maximum energy storage position, and the spring 6 releases energy and drives the energy storage shaft s to continue to rotate toward the first position until the energy storage shaft s and the mechanism housing 1 first limit fit and limit the energy storage shaft s to the first position. When the connecting rod 5 is driven by the spring 6 to switch from the third position to the fourth position, the connecting rod 5 rotates along the second direction, and the spring 6 releases energy to drive the connecting rod 5 to rotate until it establishes a fourth limit fit with the mechanism housing 1 and limits the connecting rod 5 to the fourth position; when the connecting rod 5 is driven by the spring 6 to switch from the fourth position to the third position, the connecting rod 5 rotates along the first direction, and the spring 6 releases energy to drive the connecting rod 5 to rotate until it establishes a third limit fit with the mechanism housing 1 and limits the connecting rod 5 to the third position.

[0066] like Figure 6 and 9As shown, the energy storage transmission assembly a has at least one assembly state; when the energy storage transmission assembly a is in a free state, that is, when the energy storage transmission assembly a is not assembled to the operating mechanism o, the spring 6 acts on the connecting rod 5 and the energy storage shaft s respectively, so that the connecting rod 5 and the energy storage shaft s have a tendency to rotate relative to each other in two opposite directions, so that the connecting rod 5 and the energy storage shaft s limit the matching to prevent the relative rotation of the connecting rod 5 and the energy storage shaft s, and keep the energy storage transmission assembly a in the assembly state. The assembly state of the energy storage transmission assembly a allows the energy storage shaft s, the connecting rod 5, and the spring 6 of the energy storage transmission assembly a to be pre-assembled together, and when applied to the operating mechanism o, they can be assembled into the operating mechanism o as a whole, which is conducive to reducing the assembly difficulty of the operating mechanism o, simplifying the operation, and improving the assembly efficiency. Furthermore, the energy storage transmission component a has two assembly states. In the two assembly states, the spring 6 acts on the connecting rod 5 and the energy storage shaft s respectively so that the two have a tendency to rotate relative to each other in opposite directions; in the two assembly states of the energy storage transmission component a, the energy storage shaft s has a tendency to rotate in opposite directions under the action of the spring 6, and the connecting rod 5 has a tendency to rotate in opposite directions under the action of the spring 6, that is: the two assembly states are respectively a first assembly state and a second assembly state; in the first assembly state of the energy storage transmission component a, the spring 6 acts on the energy storage shaft s so that it has a tendency to rotate in the first direction and acts on the connecting rod 5 so that it has a tendency to rotate in the second direction; in the second assembly state of the energy storage transmission component a, the spring 6 acts on the energy storage shaft s so that it has a tendency to rotate in the second direction and acts on the connecting rod 5 so that it has a tendency to rotate in the first direction. Furthermore, when the operating mechanism o is in the closed state and the open state, the energy storage transmission component a is in two assembly states respectively, that is: when the operating mechanism o is in the closed state, the energy storage transmission component a is in one assembly state, and the energy storage shaft s and the connecting rod 5 are limited in cooperation (the two are limited in cooperation in a relative posture); when the operating mechanism o is in the open state, the energy storage transmission component a is in another assembly state, and the energy storage shaft s and the connecting rod 5 are limited in cooperation (the two are limited in cooperation in another relative posture). When the operating mechanism o is in the closed state and the open state, the energy storage shaft s and the connecting rod 5 are limited in cooperation to prevent the two from rotating relative to each other, which is beneficial to reduce the impact force of the energy storage shaft s and the connecting rod 5 on the mechanism housing 1, thereby extending the service life of the operating mechanism o. It should be pointed out that when the operating mechanism o is in the closed state and the open state, the energy storage shaft s and the connecting rod 5 may not have limited cooperation. In this case, the energy storage shaft s and the connecting rod 5 need to continue to rotate relative to each other by a certain angle to establish limited cooperation.

[0067] like Figure 1-3As shown in , 5, the operating shaft 2 rotates around the axis o1-o1 and switches between the opening position and the closing position, that is, the operating shaft 2 has two working positions, which are the opening position and the closing position, respectively. The operating shaft 2 is arranged to rotate around the axis o1-o1 and switches between the opening position and the closing position by reciprocating rotation. The axis o1-o1 and the axis o2-o2 are perpendicular to each other; the operating shaft 2 is driven by an external force to reciprocate, thereby driving the energy storage shaft s to reciprocate. Further, the axis o1-o1 and the axis o2-o2 are coplanar, and the two intersect vertically.

[0068] As another embodiment, the operating shaft 2 is arranged to move linearly, and the moving direction of the operating shaft 2 is perpendicular to the axis o2-o2; the operating shaft 2 is driven by an external force to move linearly back and forth, thereby driving the energy storage shaft s to reciprocate. Further, the operating shaft 2 and the energy storage shaft s are driven by a rack and a gear; or, the operating shaft 2 is provided with a toggle part, and the energy storage shaft s is provided with two sets of corresponding driven parts, and the reciprocating movement of the operating shaft 2 causes the toggle part to press against the two driven parts respectively, thereby causing the energy storage shaft s to reciprocate.

[0069] like Figure 2-3 As shown in Figures 5-7 and 10, the operating shaft 2 includes an operating shaft driving part 2-1, and the energy storage shaft s includes an energy storage shaft driven part 4-1. The operating shaft 2 is driven by an external force to rotate and drives the operating shaft driving part 2-1 to rotate. The operating shaft driving part 2-1 drives the energy storage shaft s to rotate through the energy storage shaft driven part 4-1.

[0070] Specifically, the operating shaft driving part 2-1 includes a driving bevel gear rotatably arranged around the axis o1-o1, that is, the axis of the driving bevel gear coincides with the axis o1-o1; the energy storage shaft driven part 4-1 includes a driven bevel gear 4-12 rotatably arranged around the axis o2-o2, that is, the axis of the driven bevel gear 4-12 coincides with the axis o2-o2; the driving bevel gear is meshed with the driven bevel gear 4-12.

[0071] As other embodiments, the operating shaft driving part 2-1 is a toggle block that performs circular motion around the axis o1-o1, and the energy storage shaft driven part 4-1 includes two driven blocks that are relatively spaced apart, and the toggle block is located between the two driven blocks. The operating shaft 2 is rotated by an external force to drive the toggle block to swing, and the toggle block presses against the two driven blocks respectively to rotate the energy storage shaft s.

[0072] As another embodiment, the operating shaft 2 and the energy storage shaft s are matched through a worm gear transmission, and accordingly, the axis o1-o1 and the axis o2-o2 are not coplanar, and the two are perpendicular to each other only in space.

[0073] like Figure 1-3As shown in Figures 5 and 10, the operating shaft 2 also includes an operating shaft stem 2-0, and the mechanism shell 1 includes a shell operating shaft hole 1-00. The operating shaft stem 2-0 is rotatably inserted into the shell operating shaft hole 1-00 and is driven to rotate by external force operation, that is, the external force drives the operating shaft 2 to rotate through the operating shaft stem 2; one end of the operating shaft stem 2-0 is connected to the operating shaft driving part 2-1.

[0074] Furthermore, the other end of the operating shaft 2-0, that is, the end of the operating shaft 2-0 away from the operating shaft driving part 2-1, protrudes outside the mechanism housing 1 for operation. Of course, the end of the operating shaft 2-0 away from the operating shaft driving part 2-1 can also be flush with the outer side surface of the mechanism housing 1 or lower than the outer side surface of the mechanism housing 1.

[0075] Furthermore, the free end of the operating shaft 2-0, that is, the end of the operating shaft 2-0 away from the operating shaft driving part 2-1, is provided with an operating shaft socket 2-00; the operating mechanism o also includes an operating handle, which is inserted into the operating shaft hole 2-00 to drive the operating shaft 2 to rotate; the operating shaft 2-0 is preferably also provided with a fixing hole 2-01, which extends radially along the operating shaft 2-0 and intersects with the operating shaft socket 2-00, and a fixing screw is arranged in the fixing hole 2-01 and is threadedly connected thereto to fix the operating handle and the operating shaft 2-0 together.

[0076] Furthermore, a mechanism shell slot is provided on the inner side wall of the shell operating shaft hole 1-00, and the mechanism shell slot extends along the circumferential direction of the shell operating shaft hole 1-00; the operating shaft stem 2-0 includes a shaft positioning portion 2-02, and the shaft positioning portion 2-02 makes a circular motion around the axis o1-o1 driven by the operating shaft stem 2-0, and the shaft positioning portion 2-02 is inserted in the mechanism shell slot to limit the movement of the operating shaft 2 along the axis o1-o1 direction, thereby ensuring the reliable matching and transmission of the operating shaft 2 and the energy storage shaft s.

[0077] like Figure 1-2 As shown in Figures 6, 13 and 17, the connecting rod 5 is provided with an output structure, which passes through the side wall of the mechanism housing 1 and is used for transmission connection with the moving contact mechanism m of the switching electrical appliance.

[0078] Specifically, Fig.17As shown, at least two groups of connecting rod transmission grooves are provided on the end surface of the connecting rod shaft 5o, and at least two groups of moving contact transmission grooves are provided on the end surface of the corresponding moving contact mechanism m connected to the connecting rod shaft 5o in transmission. The connecting rod transmission grooves match the moving contact transmission grooves one-to-one and are connected through the transmission member t, that is, the two ends of each transmission member t are respectively inserted into the corresponding connecting rod transmission groove and the moving contact transmission groove. Further, the connecting rod transmission groove and the moving contact transmission groove are both arc grooves with the axis o2-o2 as the center, and the corresponding transmission member t is an arc rod-shaped transmission member. The connecting rod shaft 5o and the moving contact mechanism m are not limited to the above-mentioned transmission connection. For example: the connecting rod shaft 5o is provided with a connecting rod transmission groove coaxially arranged therewith, and the moving contact mechanism m is provided with a moving contact transmission boss coaxially arranged therewith, and the moving contact transmission boss is plugged into and matched with the connecting rod transmission groove; or, the connecting rod shaft 5o is provided with a connecting rod transmission groove coaxially arranged therewith, and the moving contact mechanism m is provided with a moving contact transmission groove coaxially arranged therewith, and the transmission member t is a cylindrical structure, and its two ends are respectively inserted into the connecting rod transmission groove and the moving contact transmission groove.

[0079] Furthermore, the output structure is performed by the connecting rod shaft 5o of the connecting rod 5, which will be described in detail below.

[0080] like Figure 1-3 As shown in , 5-7, and 13-15, the energy storage shaft s and the spring 6 are both arranged in the connecting rod 5. Further, the axial ends of the energy storage shaft s are respectively rotatably arranged on the connecting rod 5. The above-mentioned layout and assembly relationship design of the energy storage shaft s, the connecting rod 5 and the spring 6 are conducive to further improving the compactness of the structure of the operating mechanism o of this embodiment and reducing the required space.

[0081] It should be pointed out that the energy storage shaft s and the spring 6 do not have to be arranged in the connecting rod 5, and the axial ends of the energy storage shaft s do not have to be rotatably arranged on the connecting rod 5. It is only necessary to satisfy that the energy storage shaft s and the connecting rod 5 are respectively rotatably arranged around the axis o1-o1 and the spring 6 is respectively matched with the energy storage shaft s and the connecting rod 5. For example, the axial ends of the energy storage shaft s can be directly rotatably arranged on a pair of side walls of the mechanism housing 1, or the energy storage shaft s is rotatably arranged on a bracket for supporting the energy storage shaft s and the bracket is fixedly arranged on the mechanism housing 1, the spring 6 can be side by side with the connecting rod 5 in the direction of the axis o1-o1, the energy storage shaft s can be arranged side by side with the connecting rod 5 in the direction of the axis o1-o1, or the middle part of the connecting rod 5 can be rotatably sleeved on the energy storage shaft. The above only lists some possible layout methods of the energy storage shaft s, the connecting rod 5, and the spring 6. Those skilled in the art can make other deformation designs on the basis of ensuring the action mode and matching relationship of the energy storage shaft s, the connecting rod 5, and the spring 6, all of which should fall within the protection scope of the present application.

[0082] like Figure 1-2, 13-15, the connecting rod 5 is rotatably mounted on the mechanism housing 1. Further, the connecting rod 5 can be directly rotatably mounted on the mechanism housing 1, for example, the connecting rod 5 is rotatably mounted on a pair of side walls of the mechanism housing 1 through a pair of connecting rod shafts 5o, which will be described in detail below.

[0083] As other embodiments, the connecting rod 5 is indirectly rotatably arranged on the mechanism housing 1, for example, the connecting rod 5 is rotatably arranged on a bracket for supporting the connecting rod 5, and the bracket is fixedly arranged on the mechanism housing 1; or, the connecting rod 5 is indirectly rotatably arranged on the mechanism housing 1 through an energy storage shaft s.

[0084] At least one of the two axial ends of the energy storage shaft s passes through the mechanism housing 1 to provide external force to drive the energy storage shaft s to rotate.

[0085] Specifically, Figure 1-2 As shown in , 6, 13, and 15, the axial ends of the energy storage shaft s respectively pass through a pair of side walls of the mechanism housing 1, and are used to drive the energy storage shaft s to rotate by external force operation; that is, the axial ends of the energy storage shaft s respectively pass through a pair of side walls of the mechanism housing 1, and the external force can respectively operate the two ends of the energy storage shaft s to drive it to rotate. The above-mentioned design of the energy storage shaft s enables the first embodiment operating mechanism o to not only perform opening and closing operations through the operating shaft 2, but also perform opening and closing operations through the energy storage shaft s, so that the user can operate the first embodiment operating mechanism o from multiple directions, which greatly expands the application scenarios of the operating mechanism of this embodiment. In actual use scenarios, although the axial ends of the energy storage shaft s can pass through the side walls of the mechanism housing 1 for external force operation, after the switch unit p and the operating mechanism o are assembled, one of the axial ends of the energy storage shaft s will inevitably be blocked by the switch unit p. According to actual needs, the energy storage shaft s, only one axial end of which passes through a side wall of the mechanism housing 1, is used to drive the energy storage shaft s to rotate by external force operation. When the energy storage shaft s can be driven to rotate in the above manner, the operating shaft 2 can be omitted to further simplify the structure of the operating mechanism o, or more modes and directions for operating the operating mechanism o can be provided without omitting the operating shaft 2.

[0086] Further, such as Figure 3 , 5 As shown in , 6-8, and 14, the energy storage transmission assembly a includes two groups of springs 6, and the two groups of springs 6 are respectively arranged on both radial sides of the energy storage shaft s, and both ends of each group of springs 6 are respectively connected to the connecting rod 5 and the energy storage shaft s for rotation.

[0087] Specifically, the spring 6 is a linear compression spring, which includes a spring body 60 and a first connection portion and a second connection portion respectively connected to both ends of the spring body 60, the first connection portion is rotationally connected to the energy storage shaft s, and the second connection portion is rotationally connected to the connecting rod 5; Fig.16As shown in part (2), when the spring 6 is at the maximum energy storage position, the geometric axis of the spring 6 is coplanar with the axis o2-o2, and the two intersect vertically.

[0088] As another embodiment, the spring 6 may also be a torsion spring, both ends of which are rotatably connected to the energy storage shaft s and the connecting rod 5 respectively; when the spring 6 is at the maximum energy storage position, the lines connecting the points of action of the energy storage shaft s and the connecting rod 5 respectively are coplanar with the axis o2-o2, and the two intersect vertically.

[0089] like Figure 1-2 As shown, the mechanism housing 1 comprises a front half housing 1-1 and a rear half housing 1-2 that are relatively matched. Further, the front half housing 1-1 and the rear half housing 1-1 are relatively assembled together along the axis o2-o2 direction.

[0090] The specific assembly structure of the mechanism housing 1, the energy storage shaft s, the connecting rod 5, and the spring 6 as well as their respective specific structures will be described in detail below.

[0092] Specifically, the connecting rod cavity 5c includes an axial cavity 50c and a spring cavity 51c, the two spring cavities 51c are symmetrically arranged on both sides of the axial cavity 50c and communicated with it, the energy storage shaft s is rotatably arranged in the axial cavity 50c, and the two springs 6 are respectively arranged in the two spring cavities 51c. Further, in the direction of the axis o2-o2, the width of the axial cavity 50c is greater than the width of the spring cavity 51c, and the two ends of the axial cavity 50c protrude on both sides of the spring cavity 51c.

[0093] Furthermore, the connecting rod 5 is an integrated structure with higher structural strength, which is beneficial to improving the structural stability of the operating mechanism o and is beneficial to reducing the number of parts of the operating mechanism o.

For example, the first end wall 5-2 and the second end wall 5-4 may be two metal shafts, each of which is connected to the connecting rod front wall 5-1 and the connecting rod rear wall 5-3 at both ends, and the second connecting portion of the spring 6 is rotatably sleeved on the corresponding metal shaft.

Of course, according to actual needs, it is also allowed to set the switch unit p on only one side of the operating mechanism o in the direction of the axis o2-o2, and the housing output shaft hole 1o corresponding to the switch unit p is a through hole, and the other housing output shaft hole 1o can be a through hole or a blind hole.

[0097] Specifically, the two connecting rod shafts 5o are respectively arranged on the outer side surfaces of the connecting rod front wall 5-1 and the connecting rod rear wall 5-3 (that is, the two side surfaces opposite to each other of the connecting rod front wall 5-1 and the connecting rod rear wall 5-3); the two connecting rod shaft holes respectively pass through the middle of the two connecting rod shafts 5o, and the connecting rod shaft holes and the connecting rod shaft 5o are coaxially arranged; the axial ends of the energy storage shaft s are respectively rotatably arranged in the two connecting rod shaft holes and respectively pass through the two output shaft holes 1o, so as to provide external force operation to drive the operating shaft s to rotate.

[0098] As other embodiments, the connecting rod shaft 50 of the connecting rod 5 is only used as a structure for realizing the rotation setting of the connecting rod 5, and a structure for being connected to the moving contact mechanism m of the switching electrical appliance is additionally provided. For example: the connecting rod 5 is provided with a driving shaft parallel to the axis o1-o1, and the connecting rod 5 rotates to drive the moving contact mechanism m to rotate through the driving shaft; accordingly, an arc-shaped hole matching the moving trajectory of the driving shaft is provided on the side wall of the mechanism housing 1.

After the other end of the spring 6 (that is, the second arm 6-2 of the spring 6) is assembled, the first arm 6-1 will rotate relative to the connecting hole limit hole 3a, so that the avoidance surface 6-10 is staggered with the connecting hole entrance 3i, and during the rotation of the energy storage shaft s, the avoidance surface 6-10 will never be opposite to the side of the connecting hole entrance 3i. Since the outer diameter φ2 of the first arm 6-1 is greater than the width d1 of the connecting hole entrance 3i, it is ensured that the first arm 6-1 will not fall out of the connecting hole limit hole 3a, thereby ensuring the reliable and stable operation of the operating mechanism o and simplifying the assembly operation of the connecting arm 3-10 and the first arm 6-1. Furthermore, the first connecting portion is a U-shaped structure, which includes a first blocking arm, a first arm 6-1 and a second blocking arm which are connected in sequence, the first blocking arm and the second blocking arm are opposite to each other, and after the first arm 6-1 and the connecting arm 3-10 are assembled, the first blocking arm and the second blocking arm are respectively located on both sides of the connecting arm 3-10 in the direction of the axis o2-o2.

[0119] like Figure 6-8 As shown in 13, the energy storage shaft s is movably arranged along the axis o2-o2 relative to the connecting rod 5, that is, the energy storage shaft s can move relative to the connecting rod 5 in the direction of the axis o2-o2. Therefore, when the energy storage shaft s is installed in the connecting rod 5, one end of the energy storage shaft s can be inserted into one side wall of the connecting rod 5, and then the energy storage shaft s is moved along the direction of the axis o2-o2 to make the other end of the energy storage shaft s inserted into the other side wall of the connecting rod 5, thereby completing the assembly of the energy storage shaft s and the connecting rod 5, which is conducive to simplifying the assembly operation of the energy storage shaft s and the connecting rod 5.

[0120] Specifically, the connecting shaft 3-0 of the connecting shaft 3 and the driving shaft 4-0 of the driving shaft 4 are respectively located at the axial ends of the energy storage shaft s, and the free ends of the connecting shaft 3-0 of the connecting shaft 3 and the driving shaft 4-0 of the driving shaft 4 are respectively rotated and inserted on the connecting rod front wall 5-1 and the connecting rod rear wall 5-3 of the connecting rod 5; during assembly, the connecting shaft 3-0 is first inserted on the connecting rod front wall 5-1, and then the energy storage shaft s is moved along the axis o2-o2 direction to insert the free end of the driving shaft 4-0 on the connecting rod rear wall 5-3. Further, the free end of the connecting shaft 3-0 is rotated and inserted into the connecting rod front shaft hole 5-1s of the connecting rod front wall 5-1, and the free end of the driving shaft 4-0 is rotated and inserted into the connecting rod rear shaft hole 5-3s of the connecting rod rear wall 5-3.

[0121] The following will be combined Figure 8 and 12 The structure of the energy storage shaft s is further explained: in the driving shaft 4, the driven bevel gear 4-12 and the energy storage shaft matching part 4-11 are both arranged on the driven part 4-1 of the energy storage shaft, the driven bevel gear 4-12 is a fan-shaped gear, the gear teeth of the driven bevel gear 4-12 and the two energy storage shaft matching parts 4-11 are arranged at intervals along the circumference of the driven part 4-1 of the energy storage shaft, and the two energy storage shaft matching parts 4-11 are located on both sides of the driven bevel gear 4-12 in the circumferential direction of the driven part 4-1 of the energy storage shaft (that is, the circumferential direction of the energy storage shaft s). After the connecting shaft 3 and the driving shaft 4 are assembled, the connecting shaft coupling portion 3-2 of the connecting shaft 3 is completely inserted into the driving shaft coupling hole 4-20 of the driving shaft coupling portion 4-2 of the driving shaft 4, and in the direction of the axis o2-o2 (that is, in the axial direction of the energy storage shaft s), the connecting shaft trunk 3-0, the connecting portion 3-1, the driving shaft coupling portion 4-2, the driving shaft driven portion 4-1 and the driving shaft trunk 4-2 are arranged in sequence.

[0122] It should be noted that in the description of the present invention, the terms "upper", "lower", "left", "right", "inner", "outer", etc. indicate directions or positional relationships based on directions or positional relationships shown in the drawings, or directions or positional relationships that are usually placed when in use, and are only for the convenience of description, rather than indicating that the device or element referred to must have a specific direction, and therefore cannot be understood as a limitation on the present invention. In addition, the terms "first", "second", "third", etc. are only used to distinguish descriptions, and cannot be understood as indicating relative importance.

[0123] The above contents are further detailed descriptions of the present invention in combination with specific preferred implementations, and the specific implementation of the present invention cannot be considered to be limited to these descriptions. For ordinary technicians in the technical field to which the present invention belongs, several simple deductions or substitutions can be made without departing from the concept of the present invention, which should be regarded as falling within the protection scope of the present invention.
