Operating mechanism and change-over switch

Abstract

An operating mechanism and a change-over switch relate to the technical field of low-voltage apparatuses. The operating mechanism comprises a support, two energy storage assemblies, a driving part and an acting part, wherein the driving part and the acting part are rotationally connected to the support. The two energy storage assemblies are symmetrically arranged relative to the arrangement direction of the driving piece and the acting piece, and each energy storage assembly comprises a first end rotationally connected with the support and a second end movably connected with the driving piece and the acting piece. The driving piece is driven to rotate and can drive one energy storage assembly to rotate from the first position to the second position so that the energy storage assembly can store energy. The energy storage assembly releases energy and can drive the acting piece to rotate from the second position to the third position. One of the first position and the third position is an opening position and the other is a closing position; when the driving piece rotates from the first position or the third position to the second position, the rotating stroke of the driving piece is larger than the rotating stroke of the second end of the energy storage assembly driven to move. The operating mechanism can improve the reliability of closing or opening.

Description

Technical Field

[0001] The utility model relates to the technical field of low-voltage electrical appliances, in particular to an operating mechanism and a conversion switch. Background Art

[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 transfer 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 transfer switch is an important mechanism in the structural system of the entire dual power transfer switch. It is used to drive the transfer switch to close and open the switch, thereby ensuring the safety of the power system and the working continuity of the electrical equipment. However, due to the unreasonable design of the operating mechanism of the existing three-position dual power transfer switch, when the drive part is switched from the double-open position of the dual power transfer switch to the normal power on position (or the backup power on position), there may be a problem of low closing reliability caused by the energy storage mechanism being unable to cross the neutral position.

[0035] 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.

[0036] 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.

[0037] Please refer to Figure 1 and Figure 2, this embodiment provides an operating mechanism, which includes a bracket 10, two energy storage components 20, and a driving member 30 and an acting member 40 respectively connected to the bracket 10 in rotation; the two energy storage components 20 are symmetrically arranged relative to the arrangement direction of the driving member 30 and the acting member 40, and the energy storage component 20 includes a first end and a second end opposite to each other, the first end is connected to the bracket 10 in rotation, and the second end is connected to the driving member 30 and the acting member 40 in an active manner; the driving member 30 is driven to rotate and can drive one of the energy storage components 20 to rotate from the first position to the second position, so that the energy storage component 20 stores energy; the energy storage component 20 releases energy and can drive the acting member 40 to rotate from the second position to the third position; one of the first position and the third position is the opening position and the other is the closing position; when the driving member 30 rotates from the first position or the third position to the second position, the rotation stroke of the driving member 30 is greater than the rotation stroke of the second end of the driven energy storage component 20. The operating mechanism can improve the closing reliability and avoid the operating mechanism from getting stuck during the closing process.

[0038] The bracket 10 is mainly used to connect the two energy storage components 20, the driving component 30 and the working component 40, so that the various components of the operating mechanism are interconnected. In addition, the bracket 10 can also be provided with a corresponding structure for limiting the rotation angle of the energy storage component 20 and the working component 40. The present application does not limit the specific structure of the bracket 10, as long as it can play the above role.

[0039] The energy storage components 20 include two. The two energy storage components 20 are symmetrically distributed relative to the arrangement direction of the driving member 30 and the action member 40. The arrangement direction of the driving member 30 and the action member 40 is symmetrical to the arrangement direction of the driving member 30 and the action member 40. Figure 2 The first direction a is the same as Figure 2 The orientation is vertical, and the two energy storage components 20 are Figure 2 The driving members 30 and the action members 40 are horizontally distributed and are respectively located on opposite sides of the connecting line of the driving member 30 and the action member 40.

[0040] The energy storage assembly 20 has a first end and a second end that are arranged opposite to each other, wherein the first end is rotatably connected to the bracket 10, and the second end is movably connected to the bracket 10. The second end of the energy storage assembly 20 can rotate under the drive of the driving member 30, so that the energy storage assembly 20 stores energy. In addition, the energy storage assembly 20 releases energy and can drive the action member 40 to rotate, so that the action member 40 drives the contact mechanism of the transfer switch to open or close.

[0041] In this embodiment, optionally, one end of the second end close to the driving member 30 can pass through the bracket 10 to be movably connected to the driving member 30 , and one end of the second end close to the acting member 40 can pass through the bracket 10 to be movably connected to the acting member 40 .

[0042] Optionally, the driving member 30 is located on a side of the bracket 10 away from the action member 40. The driving member 30 is used to drive the second end of the energy storage assembly 20 to rotate so that the energy storage assembly 20 stores energy.

[0043] The action member 40 is located on the side of the bracket 10 away from the driving member 30, and is also used to connect with the contact mechanism of the transfer switch. The action member 40 is used to rotate under the drive of the energy storage assembly 20 to drive the moving contact of the contact mechanism to close or open the switch.

[0044] It should be noted that the operating mechanism provided in the present application can be applied to dual power supply products, wherein the dual power supply includes a normal power supply and a backup power supply. The operating mechanism provided in the present application has three states, namely, a dual split state (i.e., both the normal power supply and the backup power supply are in the split position), a normal power supply connected state, and a backup power supply connected state.

[0045] In this embodiment, when the driving member 30 rotates from the first position or the third position to the second position, the rotational stroke of the second end of the driven swinging energy storage component 20 is less than the rotational angle that the driving member 30 can rotate. Among them, one of the above-mentioned first position and the third position is the closing position, and the other is the opening position. In this embodiment, there are two corresponding closing positions (i.e., the closing position of the normal power supply and the closing position of the backup power supply) and two opening positions (i.e., the opening position of the normal power supply and the opening position of the backup power supply). The above-mentioned second position is the neutral position of the energy storage component 20, that is, the dead point position. Similarly, the second position also includes two (respectively, the neutral position of the normal power supply and the neutral position of the backup power supply).

[0046] When the driving member 30 rotates from the first position or the third position to the second position, the rotation stroke of the second end of the driven swinging energy storage assembly 20 is less than the rotation angle that the driving member 30 can rotate. In short, when the driving member 30 drives the energy storage assembly 20 to store energy, the rotation stroke that the driving member 30 can rotate is greater than the rotation stroke of the second end of the driven energy storage assembly 20. In this way, since the rotation stroke of the driving member 30 is large, the driving member 30 can continue to drive the driving member 30 to rotate after the driving member 30 drives the energy storage assembly 20 to store energy and reaches the dead point position, so that the energy storage assembly 20 passes the dead point position, thereby improving the reliability of opening and closing.

[0047] When the operating mechanism is in the double-open state, such as Figure 3 or Figure 6 As shown, at this time, both energy storage components 20 are in a natural state, and the contact mechanism is in an open state; at this time, the driving member 30 drives the second end of one of the energy storage components 20 to rotate, as shown in FIG. Figure 4 or Figure 7As shown, the driven energy storage assembly 20 rotates from the first position to the second position, and the driven energy storage assembly 20 stores energy (the other energy storage assembly 20 is still in a natural state). Since the driving member 30 can rotate to the second position, the rotation stroke of the driving member 30 is greater than the rotation stroke of the second end of the driven energy storage assembly 20. Therefore, at this time, after the driving member 30 drives the energy storage assembly 20 to move to the dead point position, the driving member 30 can continue to rotate to drive the second end of the energy storage assembly 20 to cross the dead point position. In this way, the limiting effect of another energy storage assembly 20 (the energy storage assembly 20 that is not driven to move) can be avoided, so that the movement of the driven energy storage assembly 20 has a certain margin, thereby improving the reliability of closing or opening the switch, and avoiding jamming when closing or opening the switch; after the energy storage assembly 20 passes the dead point position, the energy release effect of the energy storage assembly 20 can make the action member 40 move from the second position to the third position. When the energy storage assembly 20 needs to return from the third position to the first position, the same logic can be applied and this application will not elaborate on this.

[0048] In summary, the operating mechanism provided by the present application includes a bracket 10, two energy storage components 20, and a driving member 30 and an acting member 40 respectively rotatably connected to the bracket 10; the two energy storage components 20 are symmetrically arranged relative to the arrangement direction of the driving member 30 and the acting member 40, and the energy storage component 20 includes a first end and a second end relative to each other, the first end is rotatably connected to the bracket 10, and the second end is movably connected to the driving member 30 and the acting member 40 respectively; the driving member 30 is driven to rotate and can drive one of the energy storage components 20 to rotate from the first position to the second position, so that the energy storage component 20 stores energy; the energy storage component 20 releases energy and can drive the acting member 40 to rotate from the second position to the third position; one of the first position and the third position is an opening position and the other is a closing position; when the driving member 30 rotates from the first position or the third position to the second position, the rotational stroke of the driving member 30 is greater than the rotational stroke of the second end of the driven energy storage component 20. In the present application, when the driving member 30 rotates from the first position or the third position to the second position, the rotational stroke of the driving member 30 is set to be greater than the rotational stroke of the second end of the driven energy storage component 20. In this way, when any power supply (normal power supply or backup power supply) is closed or opened, a movement margin can be provided to the driving member 30, so that after the energy storage component 20 moves to the dead point position, the driving member 30 can continue to be driven to move, so that the energy storage component 20 can pass the dead point position. In this way, the use of the operating mechanism of the present application can improve the reliability of closing or opening, and avoid the operating mechanism from getting stuck during the closing or opening process.

[0049] Please refer to Figure 1 and Figure 2Optionally, the bracket 10 includes two support plates 11 arranged at intervals along a first direction a, and the two energy storage components 20 are respectively located between the two support plates 11. The first direction a is the same as the arrangement direction of the driving member 30 and the acting member 40; each support plate 11 is respectively provided with two symmetrical arc grooves 111, and the second end of each energy storage component 20 respectively passes through the two support plates 11 and the corresponding arc grooves 111 to be movably connected with the driving member 30 and the acting member 40 respectively.

[0050] That is, two arc-shaped grooves 111 are respectively provided on the two support plates 11. Figure 1 and Figure 2 As shown, the two support plates 11 are respectively close to the arc groove 111 on the left and are used to correspond to the energy storage assembly 20 on the left, and the two support plates 11 are respectively close to the arc groove 111 on the right and correspond to the energy storage assembly 20 on the right. The second end of each energy storage assembly 20 can be respectively inserted into the corresponding arc groove 111 and movably connected with the driving member 30 and the action member 40. In this embodiment, the arc groove 111 is a through groove.

[0051] In order to facilitate the second end of the energy storage assembly 20 to pass through the corresponding arc groove 111 and be movably connected to the driving member 30 and the action member 40, the operating mechanism optionally further includes a pin 50 connected to the second end of the energy storage assembly 20, and the opposite ends of the pin 50 respectively pass through the arc grooves 111 of the two support plates 11 to be movably connected to the driving member 30 and the action member 40, such as Figure 1 and Figure 2 shown.

[0052] Optionally, the operating mechanism further includes a rotating shaft 60, and the rotating axis of the driving member 30 and the rotating axis of the acting member 40 are colinear with the rotating shaft 60; the operating mechanism further includes a connecting member 70, one end of the connecting member 70 is rotatably connected to the rotating shaft 60, and the other end is rotatably connected to the pin 50, please refer to Figure 2 .

[0053] It should be noted that the rotation axis of the above-mentioned driving member 30 and the rotation axis of the working member 40 are colinear with the rotation shaft 60. The driving member 30 and the working member 40 may each have an independent rotation shaft, and the rotation shaft of the driving member 30 and the rotation shaft of the working member 40 are colinearly arranged; or, the rotation shaft of the driving member 30 and the rotation shaft of the working member 40 may be shared, and both are the above-mentioned rotation shaft 60 (it can also be considered that the rotation shaft of the driving member 30 and the rotation shaft of the working member 40 are integrally formed).

[0054] The arrangement of the connecting member 70 can limit the moving path of the second end of the energy storage assembly 20, thereby improving the working reliability of the energy storage assembly 20. The present application does not limit the specific structure of the connecting member 70.

[0055] Optionally, the energy storage assembly 20 includes a telescopic rod 21 and an energy storage spring 22 sleeved on the outer periphery of the telescopic rod 21; when the energy storage assembly 20 is driven to move from the first position or the third position to the second position, the telescopic rod 21 retracts and the energy storage spring 22 is compressed to store energy. When the operating mechanism includes a pin 50, the pin 50 is connected to the telescopic rod 21.

[0056] In this embodiment, two first driving grooves 31 are provided on the driving member 30, and two second driving grooves 41 are provided on the acting member 40, and the two first driving grooves 31 and the two second driving grooves 41 are arranged in a one-to-one correspondence; the second end of any energy storage component 20 is movably connected to the first driving groove 31 corresponding to the side of the driving member 30, and the second end of any energy storage component 20 is movably connected to the second driving groove 41 corresponding to the side of the acting member 40.

[0057] When the bracket 10 includes two support plates 11 arranged at intervals along the first direction a, the two energy storage components 20 are respectively located between the two support plates 11, and the first direction a is the same as the arrangement direction of the driving member 30 and the action member 40; when each support plate 11 is respectively provided with two symmetrical arc grooves 111, the second end of any energy storage component 20 is close to the side of the driving member 30, passes through the corresponding arc groove 111 on the bracket 10 and is movably connected to the corresponding first driving groove 31; the second end of any energy storage component 20 is close to the side of the action member 40, passes through the corresponding arc groove 111 on the bracket 10 and is movably connected to the corresponding second driving groove 41.

[0058] For easier understanding, please refer to Figure 1 and Figure 2 As shown, taking the energy storage assembly 20 on the right as an example, the upper portion of the second end of the energy storage assembly 20 (specifically the pin 50) passes through the arc groove 111 on the right side of the upper support plate 11, and is movably connected to the first driving groove 31 on the right side of the driving member 30; the lower portion of the second end of the energy storage assembly 20 (specifically the pin 50) passes through the arc groove 111 on the right side of the lower support plate 11, and is movably connected to the second driving groove 41 on the right side of the action member 40. The connection method of the energy storage assembly 20 on the left can be obtained in the same way, and will not be repeated here.

[0059] In this embodiment, when the driving member 30 rotates from the first position or the third position to the second position, the driving member 30 can rotate to a greater extent than the rotational stroke of the second end of the driven energy storage assembly 20, which can be achieved by the following two solutions:

[0060] For example, in the first possible implementation, please refer to Figure 3 and Figure 4When the driving member 30 rotates from the first position or the third position to the second position, the first angle α is greater than the rotation angle of the second end of the driven swinging energy storage component 20 around the rotation center of the driving member 30, and the first angle α is the angle formed by the line connecting the head end of the first driving groove 31 and the rotation center of the driving member 30 and the line connecting the tail end of the first driving groove 31 and the rotation center of the driving member 30.

[0061] The rotation angle of the second end of the driven swinging energy storage assembly 20 around the rotation center of the driving member 30 is Figure 4 In the second angle β, that is, the first angle α is greater than the second angle β. In this way, when the energy storage assembly 20 moves to the second position, there is a gap between the driving member 30 and the second end of another energy storage assembly 20 (the undriven energy storage assembly 20). At this time, in order to ensure that the driven energy storage assembly 20 can pass the dead point position, the driving member 30 can continue to be driven to rotate a small angle.

[0062] For another example, in the second feasible implementation, please refer to Figures 5 to 8 The driving member 30 is also provided with two accommodating grooves 32, which are respectively connected to the two first driving grooves 31, and the two accommodating grooves 32 respectively accommodate elastic members 80; when the driving member 30 rotates from the first position or the third position to the second position, after the second end of the energy storage assembly 20 that is not driven to swing abuts against the elastic member 80 corresponding thereto, the driving member 30 continues to move and the elastic member 80 is compressed and deformed.

[0063] That is, the driving member 30 has two accommodating grooves 32, each of which has an elastic member 80 fixedly disposed therein, and the two accommodating grooves 32 are respectively disposed at the opening driving parts of the two first driving grooves 31, such as Figure 6 and Figure 7 shown.

[0064] When the driving member 30 rotates from the first position or the third position to the second position, Figure 6 and Figure 8 As shown, the driven swinging energy storage assembly 20 can store energy and move to the second position, and the second end of the undriven energy storage assembly 20 can move to abut against the corresponding elastic member 80. At this time, if it is necessary to ensure that the driven swinging energy storage assembly 20 can pass the dead point position, the driving member 30 can continue to be driven to rotate. Since the driving member 30 and the undriven energy storage assembly 20 are elastically connected at this time, there will be no interference with the continued rotation of the driving member 30.

[0065] In order to facilitate the driven rotation of the driving member 30, optionally, a driving portion 33 is provided on a side of the driving member 30 away from the action member 40. In this way, when the driving member 30 is driven to rotate, it can be achieved by driving the driving portion 33 to rotate.
