Description

Technical Field

[0001] The embodiments disclosed herein relate generally to the field of electrical equipment technology, and more specifically to energy storage components and dual power transfer switches. Background Technology

[0002] Dual power transfer switches are important low-voltage electrical switches widely used in critical loads where power outages are unacceptable, such as in hospitals, airports, and fire stations. In a dual power transfer switch, the paired main spring assemblies need to pre-store energy and remain in a ready-to-close or ready-to-open position. Upon receiving a transfer signal, the paired main spring assemblies quickly release according to their sequence, driving the mechanism to switch between the main power supply and the backup power supply.

[0003] However, in conventional dual-power transfer switches, each pair of main spring assemblies is driven by a separate energy storage mechanism, resulting in a large number of parts, complex structure, and inability to support bidirectional energy storage (clockwise and counterclockwise). Furthermore, although the gears are stopped and the motor is de-energized after energy storage is complete, the motor does not immediately stop rotating due to inertia, potentially damaging the gears or other transmission components. Summary of the Invention

[0004] The purpose of this disclosure is to provide an energy storage component and a dual power transfer switch to at least partially solve the above-mentioned problems.

[0005] In a first aspect of this disclosure, an energy storage assembly is provided, adapted to cooperate with a drive gear and a pair of main spring assemblies of a dual power transfer switch. The energy storage assembly includes: a pair of mating gears, each mating with a corresponding main spring assembly to drive the corresponding main spring assembly to move; a transmission gear disposed between and meshing with the pair of mating gears; an actuating gear adapted to rotate synchronously with the transmission gear and including a first set of meshing teeth and a second set of meshing teeth capable of meshing with the drive gear, the first set of meshing teeth and the second set of meshing teeth being spaced apart to form a pair of notches; and a pair of movable members movably disposed on the actuating gear and each including a third set of meshing teeth adjacent to a corresponding notch and capable of meshing with the drive gear, wherein one of the movable members can be driven by the drive gear to rotate the actuating gear and the pair of movable members, and the other movable member can be driven by the drive gear to move away from the drive gear and disengage from the drive gear.

[0006] According to embodiments of this disclosure, during the clockwise or counterclockwise rotation of the drive gear, the drive gear can drive the actuation gear and the pair of moving parts to rotate as a whole. The actuation gear can drive the transmission gear to rotate, and the transmission gear can drive the pair of mating gears to rotate. In turn, each of the pair of mating gears can drive the corresponding main spring assembly to rotate so that the corresponding main spring assembly stores energy. Therefore, the energy storage component can store energy for the pair of main spring assemblies at the same time. Compared with storing energy through two sets of energy storage mechanisms, the energy storage component of the embodiments of this disclosure has a simple structure and can achieve bidirectional energy storage in both clockwise and counterclockwise directions.

[0007] Furthermore, during energy storage, one of the paired moving parts can be driven by the drive gear to rotate the actuating gear and the paired moving parts. After energy storage is complete, the other moving part of the pair rotates with the actuating gear to a position ready to mesh with the drive gear, and can also be driven by the drive gear to move away from and disengage from the drive gear. Because the other moving part is disengaged from the drive gear, even if the drive gear continues to rotate, the actuating gear and the paired moving parts as a whole will not be driven, thus avoiding damage to the gears or other transmission components.

[0008] In some embodiments, each of the paired main spring assemblies includes a mating shaft, and each of the paired mating gears includes a mating groove. The mating groove includes a pair of mating surfaces spaced apart from each other. The mating shafts of the paired main spring assemblies are each located in a corresponding mating groove and can be driven by one of the mating surfaces of the corresponding mating groove. When the corresponding mating shaft of the paired main spring assembly moves away from one of the mating surfaces of the corresponding mating groove, the corresponding mating shaft of the paired main spring assembly can move to a position spaced apart from the other mating surface of the corresponding mating groove.

[0009] In some embodiments, the energy storage assembly further includes a pair of mounting members, each of the pair of movable members including a first end, each of the pair of mounting members passing through a respective first end and connected to the actuating gear, and each of the pair of movable members being rotatable about a respective mounting member.

[0010] In some embodiments, each of the paired movable members further includes an intermediate portion connected to the first end, and the third set of meshing teeth is provided on the opposite side of the intermediate portion of the paired movable members, and when the drive gear meshes with the corresponding third set of meshing teeth, the drive gear is able to provide a force to the corresponding movable member to rotate about the corresponding mounting member.

[0011] In some embodiments, the energy storage assembly further includes an elastic element, and each of the paired movable elements further includes a second end disposed opposite to the first end, the elastic element being disposed on a side adjacent to each other of the second ends of the paired movable elements, and the elastic element being compressed.

[0012] In some embodiments, the actuating gear further includes a pair of blocking portions, each located on a opposite side of the second end of the pair of movable members, and each capable of blocking the rotation of the corresponding movable member.

[0013] In some embodiments, the energy storage assembly further includes a connector connected to the actuating gear and the transmission gear to enable the actuating gear to drive the transmission gear to rotate.

[0014] In some embodiments, the connector includes a connecting shaft, the actuating gear and the transmission gear are spaced apart along the axial direction of the connecting shaft, and the connecting shaft passes sequentially through the actuating gear and the transmission gear.

[0015] In some embodiments, along the axial direction of the connecting shaft, the third set of meshing teeth of the paired movable elements are each located on one side of a corresponding notch.

[0016] In a second aspect of this disclosure, a dual power transfer switch is provided, comprising: an energy storage component according to any of the first aspects of this disclosure; a power unit including a drive gear that engages with the energy storage component; and a pair of main spring assemblies that engage with the energy storage component.

[0033] In conventional dual-power transfer switches, one power source must be switched off first before the other can be switched on, resulting in a sequential release of the paired main spring assemblies. Each of the paired main spring assemblies in a conventional dual-power transfer switch is driven by an energy storage mechanism, resulting in numerous parts, a complex structure, and the inability to support bidirectional energy storage (clockwise and counterclockwise). Furthermore, after energy storage is complete, although the gears are limited by the limiting shaft and the motor is de-energized, the motor does not immediately stop rotating due to inertia, potentially damaging the gears or other transmission components. Embodiments of this disclosure provide an energy storage assembly 100 for a dual-power transfer switch to at least partially address the aforementioned problems. In the following sections, [further details will be provided]. Figures 1 to 8 The principles of this disclosure are described.

[0034] Figure 1 An exploded view of a dual power transfer switch according to some embodiments of the present disclosure is shown. Figure 2 A partial structural schematic diagram of an energy storage component 100 according to some embodiments of the present disclosure is shown. Figure 3 It shows Figure 2 An exploded view of a portion of the structure of the energy storage component 100 is shown. Figures 1 to 3 As shown, the energy storage assembly 100 described herein is mounted on a bracket 400 and adapted to cooperate with the drive gear 201 of the dual power transfer switch and the paired main spring assembly 300. The energy storage assembly 100 generally includes a paired mating gear 1, a transmission gear 2, an actuation gear 3, a paired moving part 4, a mounting part 5, an elastic part 6, and a connecting part 7.

[0035] like Figure 1 As shown, in some embodiments, paired meshing gears 1 are rotatably mounted on the support 400 and each meshes with a corresponding main spring assembly 300. Therefore, during the rotation of the paired meshing gears 1, each paired meshing gear 1 can drive the corresponding main spring assembly 300 to rotate, thereby storing energy in the corresponding main spring assembly 300. A transmission gear 2 is rotatably mounted on the support 400 to rotate relative to the support 400. The transmission gear 2 is positioned between and meshes with the paired meshing gears 1. Therefore, during the rotation of the transmission gear 2, the transmission gear 2 can simultaneously drive the paired meshing gears 1 to rotate.

[0036] like Figures 1 to 3 As shown, in some embodiments, the actuating gear 3 is adapted to rotate synchronously with the transmission gear 2, so that the actuating gear 3 can drive the paired meshing gear 1 to rotate via the transmission gear 2. The actuating gear 3 includes a first set of meshing teeth 31 and a second set of meshing teeth 32 capable of meshing with the drive gear 201. The first set of meshing teeth 31 and the second set of meshing teeth 32 are spaced apart to form a paired notch 101. That is, at the paired notch 101 position of the actuating gear 3, no meshing teeth are provided on the outer side of the actuating gear 3.

[0037] refer to Figures 1 to 3 In some embodiments, a pair of movable members 4 are movably disposed on the actuating gear 3. Each of the pair of movable members 4 includes a third set of meshing teeth 421 adjacent to the corresponding notch 101 and capable of meshing with the drive gear 201. During the rotation of the drive gear 201, one of the movable members 4 in the pair can be driven by the drive gear 201 to make the actuating gear 3 and the pair of movable members 4 rotate synchronously, and the other movable member 4 in the pair can be driven by the drive gear 201 to move away from the drive gear 201, so that the other movable member 4 in the pair can disengage from the drive gear 201.

[0038] According to the embodiments of this disclosure, during the clockwise or counterclockwise rotation of the drive gear 201, the drive gear 201 can drive the actuation gear 3 and the pair of moving parts 4 to rotate as a whole. The actuation gear 3 can drive the transmission gear 2 to rotate, and the transmission gear 2 can drive the pair of mating gears 1 to rotate. In turn, each of the pair of mating gears 1 can drive the corresponding main spring assembly 300 to rotate so that the corresponding main spring assembly 300 stores energy. Therefore, the energy storage component 100 can store energy for the pair of main spring assemblies 300 at the same time. Compared with storing energy through two sets of energy storage mechanisms, the energy storage component 100 of the embodiments of this disclosure has a simple structure and can realize bidirectional energy storage in both clockwise and counterclockwise directions.

[0039] Furthermore, during energy storage, one of the paired movable parts 4 can be driven by the drive gear 201 to rotate the actuating gear 3 and the paired movable parts 4. After energy storage is completed, the other movable part 4 follows the actuating gear 3 to rotate to a position ready to mesh with the drive gear 201, and the other movable part 4 can be driven by the drive gear 201 to move away from the drive gear 201 and disengage from it. Since the other movable part 4 is disengaged from the drive gear 201, even if the drive gear 201 continues to rotate, the actuating gear 3 and the paired movable parts 4 as a whole will not be driven, thereby avoiding damage to the gears or other transmission components.

[0040] It should be noted that the operation of the energy storage component 100 in this embodiment will be explained in the following text. Figures 4 to 8 Detailed description.

[0041] Return to reference Figure 1In some embodiments, each of the paired main spring assemblies 300 includes a mating shaft 301, which can be arranged in pairs and can extend through the bracket 400. Correspondingly, each of the paired mating gears 1 includes a mating groove 11, which can be arranged in pairs and includes a pair of mating surfaces 111 spaced apart from each other. The mating shafts 301 of the paired main spring assemblies 300 are each located within a corresponding mating groove 11, and each mating shaft 301 of the paired main spring assemblies 300 can be driven by one of the mating surfaces 111 of the corresponding mating groove 11. Thus, each of the paired mating gears 1 can drive the corresponding main spring assembly 300 to rotate via the driving surface 111 to store energy in the corresponding main spring assembly 300.

[0042] Continue to refer to Figure 1 Furthermore, the support 400 may include a pair of rotating shafts 401. Each of the pair of rotating shafts 401 can be connected to a corresponding main spring assembly 300 and a corresponding mating gear 1. Thus, one of the main spring assemblies 300 and one of the mating gears 1 can each rotate about the same rotating shaft 401.

[0043] Continue to refer to Figures 1 to 3 In some embodiments, each of the paired movable members 4 includes a first end 41, an intermediate portion 42 connected to the first end 41, and a second end 43 connected to the intermediate portion 42. The first end 41 and the second end 43 may be arranged opposite to each other. Each of the paired mounting members 5 passes through the corresponding first end 41 and is connected to the actuating gear 3, thereby enabling each of the paired movable members 4 to rotate about the corresponding mounting member 5 relative to the actuating gear 3. A third set of meshing teeth 421 is provided on the opposite side of the intermediate portion 42 of the paired movable members 4. When the drive gear 201 meshes with the corresponding third set of meshing teeth 421, the drive gear 201 can provide a force to the corresponding movable member 4 to rotate about the corresponding mounting member 5.

[0044] Continue to refer to Figures 1 to 3 Furthermore, an elastic member 6 is provided on the side of the second end 43 of the paired movable members 4 that is adjacent to each other. The actuating gear 3 also includes a pair of blocking parts 33, each of the pair of blocking parts 33 being located on the side of the second end 43 of the paired movable members 4 that is opposite to each other. The elastic member 6 is in a compressed state, so the elastic member 6 can press the paired movable members 4 onto the corresponding blocking part 33, and the corresponding blocking part 33 can prevent the corresponding movable member 4 from rotating.

[0045] Furthermore, since the paired blocking portions 33 are each located on opposite sides of the second end 43 of the paired movable members 4, when the drive gear 201 rotates about a constant direction, one of the movable members 4 can mesh with the drive gear 201, and one of the blocking portions 33 can prevent one of the movable members 4 from rotating about the corresponding mounting member 5, thereby allowing the actuating gear 3 and the paired movable members 4 to be driven by the drive gear 201 to rotate. However, when the actuating gear 3 and the paired movable members 4 have rotated through a certain angle, the other movable member 4 can mesh with the drive gear 201, and the other blocking portion 33 cannot prevent the other movable member 4 from rotating, thereby allowing the other movable member 4 to be driven by the drive gear 201 and disengage from the drive gear 201 to rotate. The above principle will also be combined with the following text. Figures 4 to 8 Detailed description.

[0046] Continue to refer to Figure 2 and Figure 3 The actuating gear 3 can rotate synchronously with the transmission gear 2. For example, in some embodiments, the connecting member 7 can be connected to both the actuating gear 3 and the transmission gear 2. The connecting member 7 can be connected to the bracket 400 and can rotate relative to the bracket 400. Thus, through the transmission action of the connecting member 7, the actuating gear 3 can drive the transmission gear 2 to rotate and rotate synchronously with the transmission gear 2. It should be understood that in other embodiments, the actuating gear 3 and the transmission gear 2 can be assembled using any other suitable connection method, such as the actuating gear 3, the transmission gear 2, and the connecting member 7 being integrally machined to enable the actuating gear 3 to rotate synchronously with the transmission gear 2.

[0047] Continue to refer to Figure 2 and Figure 3 In some embodiments, the connecting member 7 may include a connecting shaft. The actuating gear 3 may be spaced apart from the transmission gear 2 along the axial direction X of the connecting shaft, and the connecting shaft may pass sequentially through the actuating gear 3 and the transmission gear 2, so that the actuating gear 3 can rotate synchronously with the transmission gear 2. Furthermore, refer to... Figures 1 to 3 Since the actuating gear 3 needs to cooperate with the driving gear 201, and the space at the transmission gear 2 is already occupied, the actuating gear 3 can be further away from the bracket 400 than the transmission gear 2 in order to accommodate the actuating gear 3 and avoid interference with the actuating gear 3.

[0048] refer to Figures 1 to 3Furthermore, the paired movable members 4 are movably disposed on the side of the actuating gear 3 opposite to the transmission gear 2 to avoid interference of the internal components of the dual power supply changeover switch with the movable members 4. Of course, the paired movable members 4 can also be movably disposed on the side of the actuating gear 3 adjacent to the transmission gear 2, but interference between the transmission gear 2 and the paired movable members 4 should be avoided. The embodiments of this disclosure do not limit this.

[0049] Continue to refer to Figures 1 to 3 In some embodiments, along the axial direction X of the connecting shaft, the third set of meshing teeth 421 of the paired movable elements 4 are each located on one side of the corresponding notch 101, for example, on the same side. It is understood that the tooth pitch between adjacent meshing teeth in the third set of meshing teeth 421 is equal to the tooth pitch between adjacent meshing teeth in the first set of meshing teeth 31 and the tooth pitch between adjacent meshing teeth in the second set of meshing teeth 32, so that the drive gear 201 can simultaneously mesh with the actuating gear 3 and the paired movable elements 4.

[0050] Furthermore, the tooth pitch between the adjacent meshing teeth of the third set of meshing teeth 421 and the first set of meshing teeth 31 is equal to the tooth pitch between adjacent meshing teeth in the third set of meshing teeth 421, and the tooth pitch between the adjacent meshing teeth of the third set of meshing teeth 421 and the second set of meshing teeth 32 is also equal to the tooth pitch between adjacent meshing teeth in the third set of meshing teeth 421. Thus, the drive gear 201 can rotate in a position where the third set of meshing teeth 421 and the first set of meshing teeth 31 are adjacent to each other, and the drive gear 201 can also rotate in a position where the third set of meshing teeth 421 and the second set of meshing teeth 32 are adjacent to each other, to avoid the problem of the drive gear 201 jamming or failing to drive the actuating gear 3 or the paired moving parts 4.

[0051] Figures 4 to 8 A schematic diagram of the operation of a dual power transfer switch according to some embodiments of the present disclosure is shown. The operation of the energy storage module 100 will be described below in conjunction with... Figures 4 to 8 Detailed description.

[0052] like Figure 4 As shown, the drive gear 201 of the power unit 200 rotates counterclockwise. Since the drive gear 201 meshes with one of the paired movable parts 4 (referred to as the first movable part for easy distinction), the drive gear 201 can apply a force F to the first movable part. The force F causes the first movable part to tend to rotate clockwise around the corresponding mounting part 5, but the corresponding blocking part 33 can block the first movable part, preventing it from rotating around the corresponding mounting part 5. This allows the actuating gear 3 and the paired movable parts 4 to rotate synchronously under the drive of the drive gear 201. The actuating gear 3 and the transmission gear 2 rotate synchronously, and the transmission gear 2 drives the paired meshing gears 1 to rotate. Each of the paired meshing gears 1 drives the corresponding main spring assembly 300 and causes the corresponding main spring assembly 300 to start storing energy.

[0053] like Figure 5 As shown, the drive gear 201 continues to rotate counterclockwise, and the actuating gear 3 and the paired movable parts 4 have rotated through a certain angle. At this time, the drive gear 201 and the actuating gear 3 continue to mesh and transmit power, while the actuating gear 3 and the paired movable parts 4 continue to rotate clockwise. The other movable part 4 in the paired movable parts 4 (for ease of distinction, it is called the second movable part) rotates to a position adjacent to the drive gear 201 and is about to mesh with the drive gear 201. At this time, the paired main spring assembly 300 is at its dead point position, and the compression of the main spring of the paired main spring assembly 300 reaches its maximum.

[0054] like Figure 6 As shown, the drive gear 201 continues to rotate counterclockwise and drives the paired main spring assemblies 300 to pass the dead center position. The paired main spring assemblies 300 can drive the corresponding drive mechanism to be locked. At this time, the drive gear 201 meshes with the second movable member. If the drive gear 201 continues to rotate due to inertia, the drive gear 201 also applies a force F to the second movable member. The force F causes the second movable member to tend to rotate clockwise around the corresponding mounting member 5, but the corresponding blocking part 33 cannot stop the second movable member, such as... Figure 7 As shown, the second movable part rotates around the corresponding mounting part 5 and moves away from the drive gear 201 and disengages from the drive gear 201, so that the drive gear 201 and the second movable part can no longer mesh and transmit power.

[0055] It is understandable that since the second moving part is disengaged from the drive gear 201, even if the drive gear 201 continues to rotate, the actuating gear 3 and the pair of moving parts 4 as a whole will not be driven, thereby avoiding damage to the gear or other transmission components.

[0056] Figure 8 The dual power transfer switch shown eliminates the actuating gear 3, the paired moving parts 4, the mounting part 5, and the elastic part 6 to avoid obstructing internal components. For example... Figure 7 and Figure 8 As shown, the drive mechanism is disengaged, and the paired main spring assemblies 300 continue to release energy and reach the energy release position. During the energy release process of the paired main spring assemblies 300, the energy storage component 100 does not operate. To avoid interference between the paired main spring assemblies 300 and the energy storage component 100, refer to... Figure 8 In some embodiments, when the corresponding mating shaft 301 of the paired main spring assembly 300 moves away from one of the mating surfaces 111 of the paired mating surfaces 111 of the corresponding mating groove 11, the corresponding mating shaft 301 of the paired main spring assembly 300 can move to a position spaced apart from the other mating surface 111 of the paired mating surfaces 111 of the corresponding mating groove 11. It can be understood that the mating shaft 301 does not collide with the other mating surface 111 of the paired mating surfaces 111, thereby preventing the mating gear 1 from being driven by the corresponding mating shaft 301.

[0057] It can be seen that the above Figures 4 to 7 The working process is illustrated by taking the counterclockwise rotation of the drive gear 201 as an example. After the paired main spring assembly 300 returns to the energy release position, it needs to continue storing energy for the next cycle of power switching. Since the energy storage component 100 does not move during the return of the paired main spring assembly 300 to the energy release position, when the drive gear 201 rotates clockwise in the opposite direction, the drive gear 201 can just mesh with the third set of meshing teeth 421 of the second movable member, or the drive gear 201 can be offset from the third set of meshing teeth 421 of the second movable member by a certain angle. When the drive gear 201 rotates a certain angle, the second movable member can extend under the drive of the elastic member 6 and mesh with the drive gear 201. Then the drive gear 201 can apply a force to the second movable member, so that the second movable member tends to rotate counterclockwise around the corresponding mounting member 5. Since the corresponding blocking part 33 can block the second movable member, the second movable member cannot rotate around the corresponding mounting part 5, so that the actuating gear 3 and the pair of movable members 4 can rotate synchronously under the drive of the drive gear 201 to re-store energy.

[0058] Similarly, as the drive gear 201 continues to rotate clockwise, the first movable member can rotate around the corresponding mounting member 5 and move away from the drive gear 201 and disengage from the drive gear 201. The drive gear 201 and the first movable member can no longer mesh and transmit power, so as to avoid damage to the gear or other transmission components.

[0059] It is understood that the energy storage component 100 of the embodiments of this disclosure can realize bidirectional energy storage of the main spring component 300 in both clockwise and counterclockwise directions, so that the main spring component 300 can store and release energy clockwise, and can store and release energy counterclockwise, thereby driving the switch to close and open and realizing the switching between the main power supply and the backup power supply.

[0060] Embodiments of this disclosure also provide a dual-power transfer switch, which includes any of the energy storage components 100, power units 200, and paired main spring assemblies 300 as described above. The power unit 200 can be a drive motor, which includes a drive gear 201 that can cooperate with the energy storage component 100. The paired main spring assemblies 300 can be mounted on a bracket 400 and can cooperate with the energy storage component 100.

[0061] The energy storage components according to embodiments of this disclosure can be applied to various dual-power transfer switches to at least partially solve the above-mentioned problems.
