Description

Technical Field

[0002] In many important occasions (such as hospitals, banks, military facilities, airports, customs, chemical medicine and metallurgy industries), it is necessary to ensure the continuity of power supply. Therefore, the electrical control equipment in the above occasions needs to be equipped with a transfer switch, which is used to switch one or more load circuits from one power supply to another power supply circuit. In other words, the transfer switch ensures the dual power supply of the above occasions. More specifically, the dual power transfer switch plays the role of converting the normal power supply and the backup power supply to realize the rotation power supply to the load.

[0003] The dual power conversion switch can realize reliable switching between three positions: normal power on, backup power on, and intermediate disconnection. The function of the intermediate disconnection is to put the contact mechanism of the switch in a double-open state. Among them, the operating mechanism of the conversion switch is an important mechanism in the structural system of the entire dual power conversion switch. It is used to drive the conversion switch to close and open the gate, thereby ensuring the safety of the power system and the working continuity of the electrical equipment. However, the operating mechanism of the existing dual power conversion switch has a complex overall structure and cumbersome operation.

[0034] Driven by intelligent and automated high-tech, the smart home industry has entered a period of rapid development. The smart home industry is facing new challenges and opportunities in the transformation of technology, market and industry.

[0035] According to the function, the smart home can be divided into eight modules: entertainment system, security system, control system, lighting system, kitchen and bathroom appliance system, network and communication system, health care system, and indoor environment system. The eight modules work together to realize the whole house intelligence.

[0036] Please refer to Figure 1 and Figure 2 , this embodiment provides an operating mechanism, which includes a driving member 50, a gear mechanism composed of at least two gears, and an energy storage component 40; the driving member 50 is connected to one end of the gear mechanism through the energy storage component 40, and the other end of the gear mechanism is used to connect with the contact mechanism 200 of the conversion switch, and the gear mechanism is used to convert the input rotation angle of the driving member 50 into an output rotation angle of the contact mechanism 200 different from the input rotation angle; the driving member 50 drives one end of the energy storage component 40 to rotate from the first position to the second position, and the energy storage component 40 stores energy; the energy storage component 40 releases energy to drive the gear mechanism to rotate, so that the gear mechanism drives the contact mechanism 200 to rotate from the second position to the third position; one of the first position and the third position is the normal power connection position and the other is the standby power connection position. The operating mechanism has a simple structure and can shorten the conversion time when switching between the normal power supply and the standby power supply, thereby improving the conversion efficiency.

[0037] In order to facilitate the driving of the energy storage assembly 40, as Figure 3 and Figure 4 The operating mechanism includes the above-mentioned driving member 50, which is located on the side of the energy storage assembly 40 away from the gear mechanism, and is used to drive the energy storage assembly 40 to store energy.

[0038] In this embodiment, the driving member 50 drives the energy storage component 40 to rotate from the first position to the second position to store energy. At this time, the energy storage component 40 is driven to store energy; the driving member 50 stops driving, and the energy storage component 40 releases energy. At this time, the energy storage component 40 can drive the gear mechanism to rotate, and then drive the contact mechanism 200 to rotate through the gear mechanism, so that the contact mechanism 200 switches from the second position to the third position.

[0039] The gear mechanism is located on the side of the energy storage component away from the drive member, such as Figure 1 and Figure 4 As shown, the gear mechanism includes at least two gears, which cooperate with the contact mechanism 200 and the energy storage assembly 40 to convert the input rotation angle of the drive member 50 into an output rotation angle of the contact mechanism 200 that is different from the input rotation angle. Through this structural design, the parts of a three-station dual power switch (i.e., the dual power switch includes a normal power connection station, a double sub-station, and a backup power connection station) and the parts of a two-station dual power switch (i.e., the dual power switch only includes a normal power connection station and a backup power connection station) can be directly matched and used universally, including but not limited to the contact mechanism 200, the drive member 50, the energy storage assembly 40, and the like.

[0040] The input rotation angle of the driving member 50 and the output rotation angle of the contact mechanism 200 can be determined by those skilled in the art according to actual needs, and this application does not impose any specific restrictions.

[0041] The energy storage component 40 moves from the first position to the second position under the drive of the driving member 50 to store energy; the energy storage component 40 releases energy to drive the gear mechanism to rotate, so that the contact mechanism 200 moves from the second position to the third position. It should be noted that one of the first position and the third position is the normal power-on position, and the other is the standby power-on position. Figure 5 and Figure 6 As shown, Figure 5 and Figure 6 One of them is the normal power-on position and the other is the backup power-on position. That is, the first position can be the normal power-on position and the third position can be the backup power-on position; or the first position can be the backup power-on position and the third position can be the normal power-on position.

[0042] In addition, it should be noted that the second position is located on the motion path of the first position and the third position, and the second position is also a dead point position. When the energy storage assembly 40 stores energy under the drive of the driving member 50 and passes the dead point position, it can release energy to drive the gear mechanism to move.

[0043] It should be noted that the operating mechanism of the present application is mainly used in dual-power supply products. When the operating mechanism is applied to dual-power supply products, it can be achieved by only one action when switching between the normal power supply and the backup power supply. Compared with the existing technology (the existing operating mechanism needs to act twice when switching between the normal power supply and the backup power supply), it can save conversion time and improve conversion efficiency.

[0044] In summary, the operating mechanism provided by the present application includes a driving member 50, a gear mechanism composed of at least two gears, and an energy storage assembly 40; the driving member 50 is connected to one end of the gear mechanism through the energy storage assembly 40, and the other end of the gear mechanism is used to connect to the contact mechanism 200 of the conversion switch, and the gear mechanism is used to convert the input rotation angle of the driving member 50 into an output rotation angle of the contact mechanism 200 different from the input rotation angle; the driving member 50 drives one end of the energy storage assembly 40 to rotate from the first position to the second position, and the energy storage assembly 40 stores energy; the energy storage assembly 40 releases energy to drive the gear mechanism to rotate, so that the gear mechanism drives the contact mechanism 200 to rotate from the second position to the third position; one of the first position and the third position is the normal power connection position and the other is the standby power connection position. Through the above design, the present application only needs to act once when switching between the normal power connection position and the standby power connection position, so that one end of the energy storage assembly 40 is driven to rotate from the first position to the second position. Compared with the operating mechanism of the prior art that needs to act twice, the operating mechanism of the present application can reduce the number of operations, shorten the conversion time, and improve the conversion efficiency; in addition, compared with the prior art, the above-mentioned design of the present application can also save a set of energy storage components 40, thereby simplifying the structure of the operating mechanism, reducing the size of the operating mechanism, and reducing the difficulty of equipment manufacturing and assembly.

[0045] Optionally, in this embodiment, the gear mechanism includes an intermediate gear 10 having a first tooth portion 11 and a second tooth portion 12, an output gear 20 meshing with the first tooth portion 11, and a contact gear 30 meshing with the second tooth portion 12; the output gear 20 is transmission-connected to the energy storage assembly 40, and the contact gear 30 is transmission-connected to the contact mechanism 200; the number of teeth of the first tooth portion 11 is less than the number of teeth of the second tooth portion 12. Through this structural design, the initial input rotation angle of the driving member 50 can be amplified to the output rotation angle when it is output to the contact mechanism 200. Of course, if the output rotation angle needs to be reduced according to actual needs, it is only necessary to adjust the number of teeth of the first tooth portion 11 and the second tooth portion 12 accordingly, which is not limited here.

[0046] The intermediate gear 10 has a first tooth portion 11 and a second tooth portion 12. In this embodiment, the first tooth portion 11 and the second tooth portion 12 are stacked up and down. The first tooth portion 11 is used to mesh with the output gear 20, and the second tooth portion 12 is used to mesh with the contact gear 30. Figure 1 and Figure 7 .

[0047] The output gear 20 can mesh with the first gear of the intermediate gear 10, and can also be connected to the energy storage assembly 40. The output gear 20 can rotate under the drive of the energy storage assembly 40 to drive the intermediate gear 10 to rotate.

[0048] Please refer to Figure 8 The contact gear 30 can mesh with the second tooth portion 12 of the intermediate gear 10 and can be transmission-connected to the contact mechanism 200 of the switching switch. The rotation of the contact gear 30 can drive the contact mechanism 200 to rotate, so that the contact mechanism 200 is connected to the normal power supply or the backup power supply.

[0049] When the operating mechanism provided by the present application is in operation, the energy storage component 40 moves from the first position to the second position under the drive of the driving member 50, and the energy storage component 40 stores energy at this time; the energy storage component 40 releases energy, which can drive the output gear 20 to rotate, so that the output gear 20 drives the intermediate gear 10 to rotate by meshing with the first tooth portion 11 of the intermediate gear 10, so that the intermediate gear 10 can drive the contact gear 30 to rotate through the second tooth portion 12, so that the contact mechanism 200 of the conversion switch can be driven to operate through the contact gear 30, so that the moving contact of the contact mechanism 200 is switched from the first position to the third position. The above design of the present application can realize the switching of the operating mechanism between the normal power supply and the backup power supply with only one action, which can reduce one action compared to the operating mechanism of the prior art, thereby shortening the conversion time.

[0050] In order to save the overall space of the product, the specific position of the output gear 20 on the side plate 71 (described in detail below) does not need to be changed to increase the versatility of the parts. Figure 1 and Figure 4 Optionally, the rotation axis of the driving member 50, the rotation axis of the output gear 20 and the rotation axis of the contact gear 30 are colinear. That is, the operating mechanism of the present application can realize coaxial input and output. In this way, the output angle of the operating mechanism can be changed by setting the output gear 20, the intermediate gear 10 and the contact gear 30, so that the output angle is doubled. In addition, the present application sets the input and output of the operating mechanism to be coaxial. In this way, it can share other parts (such as the contact mechanism 200) with the operating mechanism of the prior art, and only needs to replace the corresponding transmission parts (output gear 20, intermediate gear 10 and contact gear 30), which can improve the versatility of the operating mechanism.

[0051] Optionally, the driving member 50 is located on the side of the energy storage assembly 40 away from the output gear 20, the driving member 50 is provided with a first arc groove 51, and the output gear 20 is provided with a second arc groove 21; the energy storage assembly 40 has a rotating end and a movable end, and the movable end of the energy storage assembly 40 is provided with a pin 43; one end of the pin 43 extends into the first arc groove 51, and the other end extends into the second arc groove 21.

[0052] It should be noted that the energy storage component 40 has a rotating end and a movable end, and the movable end is used to be driven to rotate around the rotating end to realize energy storage of the energy storage component 40. The present application provides a pin 43 at the movable end of the energy storage component 40, such as Figure 3 and Figure 4 As shown, one end of the pin shaft 43 can be inserted into the first arc groove 51 of the driving member 50 , and the other end can be inserted into the second arc groove 21 of the output gear 20 .

[0053] Please refer to Figure 3 and Figure 4 Optionally, the operating mechanism further includes a rotating shaft 60, and the driving member 50 and the output gear 20 are respectively rotatably connected to the rotating shaft 60; the operating mechanism further includes a connecting member 44, one end of the connecting member 44 is rotatably connected to the rotating shaft 60, and the other end is rotatably connected to the pin 43. The provision of the connecting member 44 can improve the reliability of the pin 43 moving in the first arc groove 51 and the second arc groove 21.

[0054] The specific structure of the connecting member 44 is not limited in this application, and those skilled in the art can configure it according to their needs.

[0055] like Figure 2 and Figure 3 As shown, optionally, the energy storage assembly 40 includes a telescopic rod 41 and an energy storage spring 42 sleeved on the outer circumference of the telescopic rod 41; when the energy storage assembly 40 is driven to move from the first position or the third position to the second position, the telescopic rod 41 retracts and the energy storage spring 42 stores energy. Of course, the energy storage assembly 40 including the telescopic rod 41 and the energy storage spring 42 is only an example. In other embodiments, energy storage assemblies 40 with other structures can also be used, as long as the energy storage assembly 40 can store energy when moving from the first position or the third position to the second position, and release energy when moving from the second position to the first position or the third position.

[0056] Please refer to Figure 4 Optionally, the operating mechanism also includes an actuator assembly 70, which is arranged between the driving member 50 and the output gear 20; one end of the energy storage assembly 40 is rotatably connected to the actuator assembly 70, and the other end passes through the actuator assembly 70 and is movably connected to the output gear 20 and the driving member 50 respectively.

[0057] The rotating end of the energy storage component 40 is rotatably connected to the actuator component 70 , and the movable end of the energy storage component 40 is movably arranged relative to the actuator component 70 .

[0058] Optionally, the actuator assembly 70 includes two side plates 71 that are arranged opposite to each other, and the energy storage assembly 40 is located between the two side plates 71. When a pin 43 is provided at the movable end of the energy storage assembly 40, one end of the pin 43 passes through one of the side plates 71 and extends into the first arc groove 51 of the driving member 50, and the other end of the pin 43 passes through the other side plate 71 and extends into the second arc groove 21 of the output gear 20.

[0059] In this embodiment, third arc grooves 711 are respectively provided on the two side plates 71; the output gear 20 is driven by the energy storage assembly 40 to rotate when the energy storage assembly 40 moves from the second position to the third position; the third arc groove 711 is used to limit the energy storage assembly 40 to limit the telescopic length of the energy storage assembly 40 after releasing energy.

[0060] It should be noted that the setting of the above-mentioned third arc groove 711 can also achieve giving way to the energy storage assembly 40. When the movable end of the energy storage assembly 40 is provided with a pin shaft 43, one end of the pin shaft 43 passes through the third arc groove 711 of one of the side plates 71 and extends into the first arc groove 51 of the driving member 50, and the other end of the pin shaft 43 passes through the third arc groove 711 of the other side plate 71 and extends into the second arc groove 21 of the output gear 20.

[0061] The angles of the two ends of the third arc groove 711 relative to the rotation axis of the driving member 50 are the rotation angles between the normal power-on position and the standby power-on position of the operating mechanism. For example, the angles of the two ends of the third arc groove 711 relative to the rotation axis of the driving member 50 are 120°, and the rotation angle of the output gear 20 from the second position to the third position can be greater than 60° (for example, 62°).

[0062] In the present application, the rotation angle of the output gear 20 from the second position to the third position is set to be greater than half of the angle between the two ends of the third arc groove 711 and the rotation axis of the driving member 50. In this way, it can be ensured that the energy storage assembly 40 passes the dead point position after energy storage is completed, thereby realizing reliable opening of the operating mechanism.

[0063] Another aspect of the present invention provides a transfer switch, which includes the above-mentioned operating mechanism. Since the specific structure and beneficial effects of the operating mechanism have been described in detail above, the present application will not repeat them here.
