Specifically, the primary energy storage mechanism 2 stores energy in a rotating manner, then the primary energy storage mechanism 2 releases energy to drive the output shaft 4 to rotate from a switching-on position to a switching-off position, the rotation of the output shaft 4 drives the locking assembly of the second driving structure and stores energy for the second energy storage elastic element 35, when the primary energy storage mechanism 2 releases energy to drive the output shaft 4 to rotate to a first critical position, the output shaft 4 drives the locking portion 321 of the locking assembly to slide out of one limiting groove along a first direction for unlocking, the second energy storage elastic element 35 releases energy to drive the locking assembly to drive the output shaft 4 to continue rotating, at the moment, the driving force for continuing rotating the output shaft 4 mainly comes from the secondary energy storage mechanism 3 until the output shaft 4 rotates to the switching-off position, the locking portion 321 is driven to slide into the other limiting groove along a second direction for limiting and locking, and the secondary energy storage mechanism 3 is locked again. This embodiment makes the output shaft receive the drive of energy storage mechanism 2 to rotate to first critical position once when separating brake through setting up secondary energy storage mechanism 3, and makes secondary energy storage mechanism 3 energy storage earlier and then unblock energy release, and the drive output shaft continues to rotate to separating brake position from first critical position, rotates through twice drive and to drive contact mechanism and have a bigger opening distance when opening, does benefit to the electric property of guaranteeing the product. The first critical position, namely the position where the locking part 321 of the secondary energy storage mechanism 3 slides out of a limiting groove to unlock and start to release energy, is a middle position where the output shaft 4 rotates from the switching-on position to the switching-off position; when the output shaft 4 is at the switching-on position, the locking portion 321 is in locking fit with the one limiting groove, when the output shaft 4 rotates to the first critical position, the locking portion 321 slides out of the one limiting groove to unlock and starts to release energy, when the output shaft 4 rotates to the switching-off position, the locking portion 321 is in locking fit with the other limiting groove, the output shaft 4 of the embodiment is driven by the first energy storage elastic member 26 to release energy from the switching-on position to the first critical position, and is mainly driven by the second energy storage elastic member 35 to release energy from the first critical position to the switching-off position, of course, when the second energy storage elastic member 35 just releases energy, the first energy storage elastic member 26 can provide driving force for the continuous rotation of the output shaft 4, and the driving force can be applied, and the protection range of the application can be achieved.

When the operating mechanism is switched on, one embodiment is that a technical scheme similar to a switching-off process is adopted, that is, the primary energy storage mechanism 2 stores energy in a rotating manner, then the primary energy storage mechanism 2 releases energy to drive the output shaft 4 to rotate from a switching-off position to a switching-on position, the rotating of the output shaft 4 drives the locking assembly of the second driving structure and stores energy for the second energy storage elastic element 35, when the output shaft 4 rotates to a second critical position, the locking part 321 of the locking assembly is driven to slide out from the other limiting groove along the first direction for unlocking, the second energy storage elastic element 35 releases energy to drive the locking assembly to drive the output shaft 4 to continue rotating until the output shaft 4 rotates to the switching-off position, and the locking part 321 is driven to slide into one limiting groove along the second direction for limiting and locking. The secondary energy storage mechanism 3 is locked again. However, in this solution, the secondary energy storage mechanism 3 mainly provides driving force from the second critical position to the closing position of the output shaft 4, which makes it difficult to ensure the closing speed at the time of closing. The second critical position, i.e. the position where the locking part 321 of the secondary energy storage mechanism 3 slides out of the other limiting groove to unlock and start energy release, is an intermediate position where the output shaft 4 rotates from the opening position to the closing position. It should be noted that the first critical position and the second critical position may be the same position, or may not be the same position.

In particular, as shown in fig. 1 to 3, in a preferred embodiment of the present application, the primary energy storage mechanism 2 includes a first driving structure and at least one first energy storage elastic element 26, the first driving structure further includes a transmission assembly, that is, the first driving structure includes an operating shaft 21, a transmission assembly and a rotating element 25 which are linked in sequence, and the transmission assembly and the rotating element 25 are linked with the output shaft 4 respectively, the first energy storage elastic element 26 is engaged with the rotating element 25, and the rotating element 25 rotates to enable the first energy storage elastic element 26 to rotate to a balance position to store energy, and releases energy to drive the rotating element 25 to rotate after passing through the balance position; the operating shaft 21 drives the rotating part 25 through the transmission assembly, so that the first energy storage elastic part 26 stores and releases energy to drive the output shaft 4 to rotate, and can also directly drive the output shaft 4 to rotate through the transmission assembly. During brake opening, the operating shaft 21 drives the rotating part 25 to rotate through the transmission component, the transmission component does not drive the output shaft 4 during brake opening, the rotation of the rotating part 25 enables the first energy storage elastic part 26 to release energy after crossing a balance position, namely after crossing a dead point, the first energy storage elastic part 26 releases energy to drive the rotating part 25 to rotate quickly, the rotating part 25 drives the output shaft 4 to rotate, the rotation of the output shaft 4 drives the locking component of the second driving structure and stores energy for the second energy storage elastic part 35, when the output shaft 4 rotates to a first critical position, the rotation of the output shaft 4 drives the locking part 321 of the locking component to slide out of the first limiting groove 313 for unlocking, the second energy storage elastic part 35 releases energy to drive the locking component to drive the output shaft 4 to rotate to a brake opening position, and the locking part 321 is driven to slide into the second limiting groove 314 for locking again, and the brake opening process is similar to the previous description.

The difference lies in the switching-on process, during the switching-on, the operating shaft 21 drives the rotating part 25 to rotate through the transmission assembly, and simultaneously the transmission assembly also drives the output shaft 4 to rotate, namely, the rotation of the rotating part 25 enables the first energy storage elastic part 26, and simultaneously the rotation of the output shaft 4 drives the locking assembly to enable the second energy storage elastic part 35 to store energy firstly and then release energy; when the output shaft 4 rotates to a second critical position, the rotation of the output shaft 4 drives the locking part 321 of the locking assembly to slide out of the second limiting groove 314 to unlock and release energy, and the second energy storage elastic part 35 releases energy to drive the locking assembly to drive the output shaft 4 to continue rotating to the switching-on position until the locking part 321 is driven to slide into the first limiting groove 313 to be locked again; meanwhile, after the rotation of the rotating member 25 makes the first energy storage elastic member 26 pass through the balance position, that is, pass through the dead point, the energy is released, the first energy storage elastic member 26 releases energy to drive the rotating member 25 to rotate rapidly, and the first energy storage elastic member 26 releases energy to drive the output shaft 4 to rotate to the switching-on position through the rotating member 25. In other words, in the switching-on process, after the second energy storage elastic element 35 passes over the dead point to release energy, the output shaft 4 is driven to rotate to the switching-on position all the time, and the output shaft 4 rotates to the switching-on position and the first energy storage elastic element 26 provides main driving force to ensure the switching-on speed.

Preferably, in the final stage of switching on, the first energy storage elastic element 26 and the second energy storage elastic element 3 may drive the output shaft 4 to rotate to the switching on position together, that is, after the output shaft 4 rotates to pass through the second critical position to unlock the second driving structure and the rotating element 25 rotates to pass through the equilibrium position, the first energy storage elastic element 26 and the second energy storage elastic element 3 drive the output shaft 4 to rotate to the switching on position together. Of course, the output shaft 4 can be driven to rotate to the switching-on position only by the first energy storage elastic member 26. In the whole switching-on process, the energy released by the primary energy storage mechanism 2 provides main driving force for the rotation of the output shaft 4, the energy released by the secondary energy storage mechanism 3 can also provide partial driving force for the rotation of the output shaft 4, the energy released by the secondary energy storage mechanism 3 can not provide driving force for the rotation of the output shaft 4, and whether the energy released by the secondary energy storage mechanism 3 can be adjusted according to actual requirements. In addition, in the switching-on process, whether the transmission assembly drives the output shaft 4 to rotate to the second critical position first, or the transmission assembly drives the rotation member 25 to rotate to make the first energy storage elastic member 26 cross the balance position first, all can carry out corresponding adjustment as required, only need guarantee to provide main drive power by the first energy storage elastic member 26, after the first energy storage elastic member 26 cross the balance position energy release, it can to continuously drive the output shaft 4 to rotate to the switching-on position, all belong to the protection scope of this application. The second critical position is a position where the locking part 321 of the secondary energy storage mechanism 3 slides out of the other limiting groove to unlock and start energy release, and is an intermediate position where the output shaft 4 rotates from the opening position to the closing position, when the output shaft 4 is at the opening position, the locking part 321 is in locking fit with the other limiting groove, when the output shaft 4 rotates to the second critical position, the locking part 321 slides out of the other limiting groove to unlock and start energy release, and when the output shaft 4 rotates to the closing position, the locking part 321 is in locking fit with one limiting groove; the output shaft 4 of the embodiment is driven by the transmission assembly from the opening position to the second critical position, and/or is driven by the transmission assembly after being driven first and then the first energy storage elastic member 26 releases energy, and the output shaft 4 is driven to rotate until the opening position after the first energy storage elastic member 26 releases energy.

subsequently, when the primary energy storage mechanism 2 rotates to the first energy release position (i.e. the position where the energy release of the first energy storage elastic member 26 is completed during opening), the first energy storage elastic member 26 drives the output shaft 4 to rotate to the first critical position, the second energy storage elastic member 35 completes energy storage and starts energy release, the other elastic arm 351 of the second energy storage elastic member 35 abuts against the other first blocking arm 323 of the locking member 32 (the elastic arm 351 on the right side and the first blocking arm 323 on the right side), so that the locking member 32 rapidly rotates towards the second limiting groove 314 under the energy release action of the second energy storage elastic member 35, during this process, the other elastic arm 351 gradually resets, the locking member 32 slides along the second direction by pushing the other first blocking arm 323 (the elastic arm 351 on the right side pushes the first blocking arm 323 on the right side in fig. 14), until the locking portion 321 and the second limiting groove 314 are locked, at this time, the first output shaft 41 and the second output shaft 42 synchronously rotate a certain angle, that is, that the output shaft 4 rotates from the first critical position to the second blocking position to the opening position, and the second blocking arm 23 rotates twice, and the output shaft 23 rotates twice, and the second blocking arm 232 rotates.

During the switching-on process, the operating shaft 21 rotates to drive the first transmission shaft 22 to rotate, the second gear 222 of the first transmission shaft 22 is engaged with the plurality of tooth presses 231 of the transmission plate 23 to move the transmission plate 23, so that the transmission plate 23 moves from the switching-off position to the switching-on position of the transmission plate, the first shift lever 232 of the transmission plate 23 moves against the first stop 412 of the first output shaft 41 to make the first output shaft 41 drive the second output shaft 42 to rotate for a certain angle, that is, the output shaft 4 rotates from the switching-off position to the second critical position, at this time, the rotation angle of the output shaft 4 is a third rotation angle, which is represented by γ in fig. 15, and the second energy storage elastic member 35 stores energy, and the third shift lever 242 of the second transmission shaft 24 drives the rotating member 25 to rotate against the third stop 253 of the rotating member 25 until the rotating member 25 drives the first energy storage elastic member 26 to rotate through the balance position of the pair of first energy storage elastic members 26; after the first energy storage elastic element 26 rotates past the equilibrium position to release energy, the rotating element 25 rapidly rotates under the action of the energy released by the pair of first energy storage elastic elements 26, so that the third stop 253 abuts against the second shift lever 413 of the first output shaft 41 to drive the first output shaft 41 and the second output shaft 42 to rotate to the second critical position;

in the process that the output shaft 4 rotates from the switching-on position to the second critical position, because the locking portion 321 of the locking member 32 and the second limiting groove 314 have no rotation allowance, the first output shaft 41 and the second output shaft 42 drive the pressing member 33 to rotate when synchronously rotating, the rotation of the pressing member 33 overcomes the elastic force of the second energy storage elastic member 35 to store energy for the second energy storage elastic member 35, that is, when the locking portion 321 is in blocking fit with the second limiting groove 314, the second blocking arm 331 of the pressing member 33 is dislocated with the first blocking arm 323 of the locking member 32, the first blocking arm 323 on one side of the locking member 32 is abutted with one elastic arm 351 of the second energy storage elastic member 35 (the first blocking arm 323 on the left side is abutted with the elastic arm 351 on the left side in fig. 15), the other elastic arm 351 is rotated and pressed by the second latch arm 331 positioned at the other side to store energy (the right elastic arm 351 and the right second latch arm 331 in fig. 15), and at the same time, one engaging portion 333 of the pressing member 33 presses the first latch arm 323 of the adjacent locking member 32 (i.e., the right engaging portion 333 and the right first latch arm 323 in fig. 15), so that the locking member 32 is slidably engaged with the sliding member 36 in the first direction, i.e., slides toward the central axis direction of the second output shaft 42 until the locking portion 321 is separated from the second limit groove 314 to be unlocked;

after the output shaft 4 rotates to the second critical position, the second energy storage elastic element 35 releases energy, the first energy storage elastic element 26 continues to release energy to enable the first output shaft 41 and the second output shaft 42 to continue to rotate in the closing direction, along with the energy release of the second energy storage elastic element 35, one elastic arm 351 of the second energy storage elastic element 35 abuts against the first blocking arm 323 of the locking element 32 (that is, the elastic arm 351 on the left side in fig. 15 abuts against the first blocking arm 323 on the left side), so that the locking element 32 rapidly rotates under the energy release action of the second energy storage elastic element 35, meanwhile, the elastic arm 351 gradually resets to push the first blocking arm 323 to enable the locking element 32 to slide in the second direction until the locking portion 321 is in limit fit with the first limiting groove 313 to achieve locking, at this time, the first output shaft 41 and the second output shaft 42 are driven by the primary energy storage elastic element 2 to rotate to the closing position, the primary energy storage element 2 is located at the second energy release position (that the rotation angle from the second critical position to the closing position is the fourth rotation angle δ shown in fig. 15.
