While preferred embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure may be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that the present disclosure will be thorough and complete, and will fully convey the scope of the present disclosure to those skilled in the art.

The terms "a first," "a second," etc. do not mean "the one and only," but rather mean the first mentioned (and the second mentioned, etc.), unless expressly specified otherwise.

[0031] As described above, the pair of main spring assemblies in the conventional dual power transfer switch each include a pair of energy storage states and a pair of energy release states, thus it is necessary to indicate the above states of the main spring assemblies. Embodiments of the present disclosure provide an energy storage indicator 100 and a dual power transfer switch to at least partially solve the above problems. In the following, the energy storage indicator 100 and the dual power transfer switch will be described in detail in conjunction with the accompanying drawings. Figures 1 to 10 The principles of the present disclosure are described.

[0032] Figure 1 A partial structural schematic diagram of a dual power transfer switch according to some embodiments of the present disclosure is shown. Figure 2 A structural schematic diagram of an energy storage indicator 100, a rotating member 201, a limiting member 202 and a cooperating shaft 301 according to some embodiments of the present disclosure is shown. As shown in the figure, the energy storage indicator 100 is rotatably arranged on a bracket 200 of the dual power transfer switch, and can be driven by a main spring assembly 300 of the dual power transfer switch. Figure 1 And Figure 2 As shown, the energy storage indicator 100 described herein is adapted to be rotatably arranged on the bracket 200 of the dual power transfer switch, and can be driven by the main spring assembly 300 of the dual power transfer switch. The energy storage indicator 100 includes a rotating part 1, a cooperating part 2, an indicating part 3 and a reset member 4 arranged on the rotating part 1.

[0033] Referring to Figure 1 And Figure 2 In some embodiments, the rotating part 1 is rotatably arranged on the bracket 200. The cooperating part 2 is coupled to the rotating part 1, and can cooperate with the cooperating shaft 301 of the main spring assembly 300 to be driven by the cooperating shaft 301. The indicating part 3 is arranged on the rotating part 1 away from the cooperating part 2. Thus, the overall structure (for the convenience of description, referred to as a cooperating member) composed of the rotating part 1, the cooperating part 2 and the indicating part 3 can be synchronously rotated. The indicating part 3 includes a release indication mark 311 and a pair of energy storage indication marks 312, and the release indication mark 311 is located between the pair of energy storage indication marks 312.

[0034] According to an embodiment of the present disclosure, the cooperating portion 2 can be driven by the cooperating shaft 301 of the main spring assembly 300, and thus the state of the main spring assembly 300 can be indicated according to the position of the indicating portion 3. When the indicating portion 3 is turned to the position where the discharged indicating mark 311 can be observed, the energy storage indicating member 100 indicates that the main spring assembly 300 is in the discharged state; and when the indicating portion 3 is turned to the position where the energy storage indicating mark 312 can be observed, the energy storage indicating member 100 indicates that the main spring assembly 300 is in the energy storage state.

[0035] It should be noted that, since the pair of main spring assemblies 300 of the double power transfer switch can be driven by the same energy storage assembly, and the pair of main spring assemblies 300 are in the energy storage state and the discharged state at the same time, only one energy storage indicating member 100 is needed to cooperate with one of the pair of main spring assemblies 300 to indicate the state of the pair of main spring assemblies 300 at the same time. Without the need to set the pair of energy storage indicating members 100 to cooperate with the corresponding main spring assemblies 300 respectively, the product cost is reduced. However, in the case that the pair of main spring assemblies 300 are driven by the corresponding energy storage assemblies respectively, the pair of energy storage indicating members 100 should be set to cooperate with the corresponding main spring assemblies 300 respectively to indicate the state of each main spring assembly 300 respectively.

[0036] The indicating marks according to the embodiments of the present disclosure can be various types of indicating marks that can play an indicating effect, and the embodiments of the present disclosure do not limit this. For example, in some embodiments, the discharged indicating mark 311 can include the word indicating mark "Discharged", and the energy storage indicating mark 312 can include the word indicating mark "Charged". Of course, in other embodiments, the discharged indicating mark 311 and the energy storage indicating mark 312 can be distinguished by color or other types of words. The embodiments of the present disclosure do not limit this.

[0037] Figure 3 and Figure 4 The structure schematic diagrams of the rotating portion 1, the cooperating portion 2 and the indicating portion 3 according to some embodiments of the present disclosure are shown. As shown in FIG. 1, the rotating portion 1 can include a rotating shaft 11, and the cooperating portion 2 can be arranged on the rotating shaft 11. The indicating portion 3 can be arranged on the rotating shaft 11 and can be arranged on the cooperating portion 2. Figure 3 and Figure 4 As shown in FIG. 1, in some embodiments, the indicating portion 3 can include an arc surface 31 extending along the rotating direction of the energy storage indicating member 100. The arc surface 31 can be arranged away from the cooperating portion 2 to make the indicating marks more easily observed. The discharged indicating mark 311 and the pair of energy storage indicating marks 312 can be arranged on the arc surface 31, and along the rotating direction of the energy storage indicating member 100, the discharged indicating mark 311 can be arranged between the pair of energy storage indicating marks 312.

[0038] It can be understood that, since the energy storage indicator 100 is rotatably arranged, the energy release indicator 311 and the pair of energy storage indicators 312 are arranged on the arc surface 31 extending along the rotation direction of the energy storage indicator 100, the distance between the energy release indicator 311 and the energy storage indicator 312 can be reasonably arranged according to the rotation distance of the indicator 3, so as to ensure that the energy release indicator 311 and the pair of energy storage indicators 312 can be observed, thereby ensuring the indication effect.

[0039] Reference Figures 2 to 4 In some embodiments, the support 200 can include a rotating member 201. The rotating part 1 can include a rotating hole 11, and the rotating member 201 can cooperate with the rotating hole 11 to enable the rotating part 1 to rotate relative to the support 200 about the rotating member 201. Thus, the energy storage indicator 100 can be rotatably arranged on the support 200.

[0040] Figure 5 A structural schematic diagram of the energy storage indicator 100 according to some embodiments of the present disclosure is shown. As Figures 1 to 5 shown, in particular, the reset member 4 can be arranged on the rotating part 1 for bidirectional reset cooperation. Preferably, the rotating part 1 can further include a mounting part 12 adjacent to the support 200, and a portion of the rotating hole 11 can be arranged in the mounting part 12. The reset member 4 can be arranged around the mounting part 12.

[0041] The reset member 4 according to the embodiments of the present disclosure can be various types of reset members 4 currently known or available in the future, and the embodiments of the present disclosure are not limited thereto. For example, in some embodiments, the reset member 4 can be a torsion spring.

[0042] Continuing to refer to Figure 1 and Figure 5 In some embodiments, the torsion spring can be arranged around the mounting part 12 and can include a pair of torsion arms 41 intersecting each other. The end portions of the pair of torsion arms 41 can each be bent away from the support 200 to constitute a bent portion 411. The indicator 3 can be located between the bent portions 411 of the pair of torsion arms 41. Thus, during cooperation of the indicator 3, the corresponding bent portion 411 can be driven to drive the corresponding torsion arm 41 to act, and then the torsion spring can store energy for subsequent reset process. The working principle of the torsion spring will be described in detail below in conjunction with Figures 6 to 10 .

[0043] Continuing to refer to Figure 2 and Figure 5In some embodiments, the bracket 200 can further include a limiting member 202. The limiting member 202 can be located between the pair of torsion arms 41 and abut against the side of the pair of torsion arms 41 away from the rotating member 201. Thus, in the case that the pair of torsion arms 41 is not driven, the position of the pair of torsion arms 41 can be limited by the limiting member 202, so that the position of the torsion spring is maintained.

[0044] With continued reference to Figure 4 and Figure 5 Further, the indicating part 3 can further include an arc-shaped hole 32 extending along the rotating direction of the energy storage indicating member 100. The limiting member 202 can be located in the arc-shaped hole 32, so that the limiting member 202 can also limit the indicating part 3. During the rotation of the energy storage indicating member 100, the limiting member 202 can move relative to the arc-shaped hole 32. It can be understood that during the rotation of the energy storage indicating member 100, the limiting member 202 is always spaced apart from the inner surface of both ends of the arc-shaped hole 32, so as to avoid the interference of the limiting member 202 with the energy storage indicating member 100.

[0045] With reference back to Figure 1 , Figure 2 and Figure 5 In some embodiments, in the case that the position of the torsion spring is maintained, the bent portions 411 of the pair of torsion arms 41 can each be spaced apart from the outer surface of the indicating part 3, so that the pair of torsion arms 41 does not provide a force to the indicating part 3. On the other hand, since the bent portions 411 of the pair of torsion arms 41 can each be spaced apart from the indicating part 3 and the distance between the bent portions 411 and the indicating part 3 is small, in the case that the cooperating shaft 301 does not drive the cooperating part 2 to rotate, the indicating part 3 can rotate within a small range between the pair of torsion arms 41, so that the position of the energy storage indicating member 100 is maintained. And since the indicating part 3 can rotate within a small range, it avoids the energy release indicating mark 311 not being easily observed due to a large rotation range.

[0046] With reference back to Figure 2 In some embodiments, during the rotation of the cooperating shaft 301 to drive the cooperating part 2 to rotate, the cooperating part 2 can be rotated to a position disengaged from the cooperating shaft 301. Since the cooperating part 2 can be disengaged from the cooperating shaft 301, the resetting member 4 can release energy and reset the cooperating member. For the above principle, it will be described in detail below in connection with Figures 6 to 10 .

[0047] Figures 6 to 10 A working schematic diagram of the energy storage indicating member 100 according to some embodiments of the present disclosure is shown. As Figure 5 and Figure 6As shown, the paired main spring assemblies 300 are in the energy release state (for ease of distinction, this is referred to as the clockwise energy release state). Since the mating shaft 301 is spaced apart from the mating part 2 and does not drive the mating part 2, the energy storage indicator 100 is in the initial position under the action of the reset member 4. The operator can observe the energy release indicator mark 311 through the indicator hole 401 on the housing 400 to indicate that the paired main spring assemblies 300 are in the clockwise energy release state.

[0048] like Figure 5 , Figure 6 and Figure 7 As shown, the paired main spring assemblies 300 begin to rotate counterclockwise, and begin to drive the mating part 2 to rotate. (Reference) Figure 7 The energy storage indicator 100 rotates clockwise around the rotating member 201 for a certain distance, and the indicator 3 begins to drive the right torsion arm 41 of the pair of torsion arms 41 to move, and the torsion spring begins to store energy.

[0049] like Figure 5 , Figure 7 and Figure 8 As shown, the paired main spring assembly 300 continues to rotate counterclockwise to the position of being in the energy storage state (for ease of distinction, this is called the counterclockwise energy storage state), and continues to drive the mating part 2. The energy storage indicator 100 continues to rotate clockwise around the rotating part 201. The indicator part 3 further drives the right torsion arm 41 of the paired torsion arms 41 to move. The operator can observe one of the paired energy storage indicator marks 312 (for ease of distinction, this is called the first energy storage indicator mark) through the indicator hole 401 on the housing 400 to indicate that the paired main spring assembly 300 is in the counterclockwise energy storage state. At this time, the mating part 2 is ready to disengage from the mating shaft 301.

[0050] like Figure 5 , Figure 8 and Figure 9 As shown, the paired main spring assembly 300 continues to rotate counterclockwise to a position in the energy-releasing state (referred to as the counterclockwise energy-releasing state for ease of distinction). During the rotation of the paired main spring assembly 300, the mating part 2 disengages from the mating shaft 301. The torsion spring releases energy and drives the mating part to return to its initial position counterclockwise. The operator can observe the energy-releasing indicator mark 311 through the indicator hole 401 on the housing 400 to indicate that the paired main spring assembly 300 is in the counterclockwise energy-releasing state.

[0051] like Figure 5 , Figure 9 and Figure 10As shown, in the next rotation cycle, the pair of main spring assemblies 300 rotate in the opposite direction clockwise to a position in the energy storage state (for the convenience of distinction, referred to as the clockwise energy storage state), the main spring assemblies 300 drive the matching part 2, and make the matching part rotate counterclockwise. The indicating part 3 can drive the left torsion arm 41 in the pair of torsion arms 41 to act. The operator can observe another energy storage indicating mark 312 (for the convenience of distinction, referred to as the second energy storage indicating mark) in the pair of energy storage indicating marks 312 through the indicating hole 401 on the shell 400 to indicate that the pair of main spring assemblies 300 is in the clockwise energy storage state.

[0052] It should be noted that, as shown in Figure 10 and Figure 6 , the pair of main spring assemblies 300 are switched from the clockwise energy storage state to the clockwise energy release state, which is similar to the energy release process shown in Figure 8 and Figure 9 , which will not be described here.

[0053] According to an embodiment of the present disclosure, the pair of main spring assemblies 300 includes a clockwise energy storage state and a clockwise energy release state in the clockwise rotation process, and includes a counterclockwise energy storage state and a counterclockwise energy release state in the counterclockwise rotation process, which can be indicated by the energy release indicating mark 311 and the energy storage indicating mark 312 in the energy storage indicating part 100.

[0054] The embodiment of the present disclosure also provides a dual power transfer switch, which includes any one of the energy storage indicating parts 100 described above; the energy storage indicating part 100 is coupled to the bracket 200; and the main spring assembly 300 is coupled to the bracket 200 and includes a matching shaft 301, which can drive the energy storage indicating part 100 to rotate.

[0055] The energy storage indicating part according to the embodiment of the present disclosure can be applied to various dual power transfer switches to at least partially solve the above-mentioned problems. It should be understood that the energy storage indicating part according to the embodiment of the present disclosure can also be applied to other electrical components, and the embodiment of the present disclosure does not limit this.

[0056] The above has described the embodiments of the present disclosure, and the above description is exemplary, not exhaustive, and is not limited to the disclosed embodiments. Many modifications and changes are obvious to those skilled in the art without departing from the scope and spirit of the described embodiments. The choice of terms used herein is intended to best explain the principles, practical applications, or technical improvements in the market of the embodiments, or to enable other ordinary skilled persons in the art to understand the embodiments disclosed herein.
