The spring operating mechanism is a mechanical operating mechanism with an energy storage spring as an energy storage element. The energy storage of the spring is completed by the energy storage shaft through the reduction device, and is maintained in the energy storage state through the lock system. When breaking, the lock is released, the energy storage spring releases energy, and the crank arm drives the switch to move through the mechanical transmission unit. The spring operating mechanism includes a manual spring operating mechanism and an electric spring operating mechanism. Usually, the electric spring operating mechanism includes a manual spring operating part and an electric control spring operating part.

It solves the problem that the existing spring operating mechanism only has the closing function, which makes the product troublesome during assembly and debugging, and has a small scope of application. It includes two side plates and a reinforcement plate. A cavity for accommodating an opening mechanism is formed between the reinforcement plate and one of the side plates. The opening mechanism includes a drive shaft, an opening crank arm and an opening spring. The drive shaft is linked to the drive plate on the closing mechanism.

[0051] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0052] like Figures 1 to 10 As shown, an electric spring operating mechanism with a clutch provided by the present invention is essentially a mechanism in which the power input source can be automatically clutched during the energy storage and release process of the closing spring, which can ensure that the energy storage and release processes do not interfere with each other, so as to ensure the stability during the closing or opening process;

[0053] The mechanism includes a power output shaft 2 for providing power for closing or opening the switch. During the energy storage process, the power output shaft 2 is rotated by the extrusion of the pin rod 23 and the upper limit block 311 of the worm gear 3, and drives the spring rod 22 to compress and complete the energy storage. After the worm gear 3 rotates to a certain extent, the pin rod 23 is separated from the limit block 311. At this time, the energy storage of the spring rod 22 is completed. At this time, the worm gear 3 drives the clutch sleeve 6 to slide horizontally through the transmission plate 7 to complete the cutting off of the power source, and then the worm gear 3 rotates to squeeze the positioning rod 332, so that the positioning rod 332 releases the limit on the positioning seat 32 at the bottom end of the power output shaft 2. At this time, the power output shaft 2 is affected by the release of kinetic energy of the spring rod 22 and rotates to complete the closing or opening work.

[0054] In terms of specific structural installation, the structural body can be constructed according to the inventive concept of this embodiment, and no special limitation is made in this embodiment.

[0055] In this embodiment, an electric spring operating mechanism with a clutch includes:

[0056] The housing 1 is a square structure with a cavity inside;

[0057] A power output shaft 2 is arranged inside the housing 1 and both ends of the shaft extend to the outside of the housing 1;

[0058] The swing arm 21 and the spring rod 22, the swing arm 21 is fixedly arranged at the middle part of the power output shaft 2, the spring rod 22 is rotatably arranged inside the housing 1, and one end of the spring rod 22 is connected to one end of the swing arm 21, and the power output shaft 2 rotates to compress the spring rod 22 to store energy;

[0059] The pin rod 23 is located at the connection between the swing arm 21 and the spring rod 22. The pin rod 23 can rotate with the swing arm 21. Since the pin rod 23 and the limit block 311 perform circular motions with different trajectories, the pin rod 23 disengages from the limit block 311 after moving within a certain range, and the energy storage process ends at this time.

[0060] The driven crank arm 24 and the oil buffer 25, the driven crank arm 24 is set to a "V" shape structure and is located at the top of the power output shaft 2, and the oil buffer 25 is provided with two groups and is located at the top of the inner wall of the housing 1.

In the final stage of energy storage, the pin rod 23 is separated from the limit block 311, and the spring rod 22 applies a force to the power output shaft 2 through the swing arm 21. At this time, the positioning rod 332 blocks the positioning block 321 to achieve the limit of the power output shaft 2, so as to prevent the clutch sleeve 6 from being released during the clutch process.

[0067] The flange 322 and the travel switch 323 are arranged on the outer side of the positioning seat 32, and the travel switch 323 is arranged on the inner bottom end of the housing 1. The flange 322 rotates with the positioning seat 32 and the power output shaft 2 and detects the rotation range of the power output shaft 2 through the travel switch 323.

When the slide rods 63 slide along the arc-shaped slide groove 61, they squeeze the clutch sleeve 6 to make it slide horizontally. It should be noted that when the clutch sleeve 6 slides horizontally, the slide rods 63 enter and exit the arc-shaped slide groove 61 under the guidance of the arc-shaped slide groove 61, so as to realize the clutch sleeve 6 and the power shaft 5 or the input shaft 41.

[0079] An auxiliary switch push plate 71 is disposed below the transmission plate 7 and a connecting rod 711 is disposed between the transmission plate 7;

[0080] An auxiliary switch 72, which is arranged at the inner bottom end of the housing 1;

[0081] A transmission shaft 73 is rotatably disposed at the inner bottom end of the housing 1, and a manual rotating rod 74 is disposed at the top end of the transmission shaft 73 via a bevel gear set;

[0082] Transmission arms 75, which are provided in two sets and are respectively located at the output shaft of the auxiliary switch 72 and the bottom end of the transmission shaft 73;

[0083] The strip groove 751 and the movable rod 752, the strip groove 751 is arranged in the middle part of the transmission arm 75, the movable rod 752 is slidably arranged inside the strip groove 751 and is located below the auxiliary switch push plate 71, the auxiliary switch 72 and the transmission shaft 73 drive the transmission arm 75 to rotate to drive the auxiliary switch push plate 71 to slide horizontally, and the auxiliary switch push plate 71 drives the slide 64 and the clutch sleeve 6 to slide horizontally through the transmission plate 7 to achieve the clutch effect. It should be noted that the auxiliary switch 72 is used to output the lagging signal after the arrival signal of the transmission shaft 2.

[0084] When using an electric spring operating mechanism with a clutch of the present embodiment, when the device performs a closing or opening operation, the power output shaft 2 can be rotated under the drive of the motor 51 or the rotating handle 42, and the spring rod 22 is slowly compressed to complete energy storage. After the spring rod 22 completes energy storage, the clutch sleeve 6 slides horizontally to complete the release of power input. At this time, the spring rod 22 quickly releases kinetic energy, so that the power output shaft 2 quickly reverses to complete the closing or opening operation;

[0085] During the energy storage process, the motor 51 drives the power shaft 5 to rotate through the connecting gear 52, the power shaft 5 drives the clutch sleeve 6 to rotate through the slide bar 63 and the strip slide groove 62, the clutch sleeve 6 drives the input shaft 41 to rotate through the slide bar 63 and the strip slide groove 62, the input shaft 41 drives the worm 4 to rotate, the worm 4 drives the worm wheel 3 to rotate, the transmission seat 31 above the worm wheel 3 squeezes the pin rod 23 through the limit block 311 to make it move, the pin rod 23 drives the power output shaft 2 to rotate through the swing arm 21, and drives the spring rod 22 to compress, so as to complete the energy storage process;

[0086] The locking cam 331 is engaged with the locking cam 332 and the locking cam 333 is engaged with the locking cam 331. The locking cam 332 is engaged with the locking cam 332 and the locking cam 333 is engaged with the locking cam 331.

[0087] In the final stage of the energy storage process, the worm gear 3 rotates to a certain angle, and the pulley 703 under the worm gear 3 slides into the slot 701. The worm gear 3 squeezes the slot 701 through the pulley 703 to make the transmission plate 7 slide horizontally. The transmission plate 7 drives the clutch sleeve 6 to slide horizontally through the slide seat 64, so that a group of strip slide grooves 62 on the clutch sleeve 6 are separated from the slide rod 63. At this time, the power input of the worm 4 can be released. At this time, the worm 4 and the worm gear 3 stop rotating. At this time, another group of pressure blocks 334 under the worm gear 3 rotate to the top of the positioning rod 332. The positioning rod 332 is squeezed and moves downward so that the release groove 333 coincides with the groove 331. At this time, the limit of the positioning block 321 is released. At this time, the limit of the positioning seat 32 and the power output shaft 2 is released, and the spring rod 22 quickly releases kinetic energy, so that the power output shaft 2 quickly rotates to complete the closing or opening operation;

[0088] When the spring rod 22 is released in the middle, the energy released by the spring rod 22 drives the output shaft 2 to rotate. At this time, the pulley 703 under the worm gear 3 is inserted into the card slot 701, and drives the transmission plate 7 to slide horizontally. The transmission plate 7 drives the auxiliary switch push plate 71 to slide horizontally. The auxiliary switch push plate 71 drives the auxiliary switch 72 to rotate, so that an auxiliary switch 72 is disconnected and sends a signal. Then, the spring rod 22 is quickly released, and the output shaft 2 rotates to the right position. Since the kinetic energy of the spring rod 2 is released quickly, the auxiliary switch 72 sends a signal after a delay of a certain period of time after the output shaft 2 rotates to the right position. Therefore, the effect of an auxiliary switch 72 signal lagging behind the output shaft 2 in-position signal can be achieved. The motor 51 continues to drive the worm gear 3 to rotate, and the worm gear 3 pushes the transmission plate 7 and the auxiliary switch push plate 71 to move. When the worm gear 3 rotates and moves by an angle, the transmission plate 7 drives the clutch sleeve 6 to slide, so that the power input of the worm 4 is released. At this time, another auxiliary switch 72 is turned on and sends a signal. Since the motor 51 drives the worm gear 3 to continue to rotate for a certain period of time after the output shaft 2 is in place, there is a time difference between the signal of the output shaft 2 in place and the signal of the auxiliary switch push plate 72, thereby achieving the effect that the signals of the two auxiliary switches 72 are both delayed behind the signal of the output shaft 2 in place. At the same time, rotating the handle 74 can also realize the control of the auxiliary switch 72 to achieve the effect of delayed output of the control signal.

[0089] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, it is still possible for those skilled in the art to modify the technical solutions described in the aforementioned embodiments or to make equivalent substitutions for some of the technical features therein.
