Description

Technical Field

[0001] The invention relates to the technical field of low-voltage electrical appliances, and in particular to an action mechanism and an isolating switch. Background Art

[0002] As a switching device, the isolating switch is mainly used for "isolating power supply, switching operation, connecting and disconnecting small current circuits", and has no arc extinguishing function. When the isolating switch is in the open position, there is an insulation distance that meets the specified requirements and an obvious disconnection mark between the contacts; when in the closed position, it is a switching device that can carry the current under normal circuit conditions and the current under abnormal conditions (such as short circuit) within a specified time.

[0003] Among them, when a circuit fails, the isolating switch, as a key component of the disconnecting function, has been widely used in various circuits because it can disconnect the circuit in the shortest time and protect other components. However, the overall structure of the existing isolating switch occupies a large volume in the height direction, which does not meet the market demand for miniaturization of isolating switches and limits the use of isolating switches in application scenarios with restricted height.

[0012] Optionally, the action mechanism further includes an energy storage component, which is disposed between the rotating component and the second vertical plate.

DETAILED DESCRIPTION

[0026] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Generally, the components of the embodiments of the present invention described and shown in the drawings here can be arranged and designed in various different configurations.

[0027] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the invention claimed for protection, but merely represents selected embodiments of the present invention. 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.

In addition, the terms "first", "second", "third", etc. are only used to distinguish the description, and cannot be understood as indicating or implying relative importance.

[0030] In addition, the terms "horizontal", "vertical" and the like do not mean that the components are required to be absolutely horizontal or suspended, but can be slightly tilted. For example, "horizontal" only means that its direction is more horizontal than "vertical", and does not mean that the structure must be completely horizontal, but can be slightly tilted.

[0031] In the description of the present invention, it is also necessary to explain that, unless otherwise clearly specified and limited, the terms "set", "install", "connect", and "connect" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two elements. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0032] Please refer to Figures 1 to 3 This embodiment provides an action mechanism, which includes an action component, and the action component includes a mechanism bracket 10 and a connecting rod mechanism 40 connected in a transmission manner; the mechanism bracket 10 is driven to rotate, and can drive the connecting rod mechanism 40 to move so that the contact mechanism 400 in the body 300 of the disconnector is opened or closed; along the rotation axis direction of the mechanism bracket 10, the positive projection of the action component on the body 300 partially overlaps with the body 300; the mechanism bracket 10 includes a bracket body 11 and a bending portion 12 connected to the bracket body 11, and the width of the bracket body 11 along the rotation axis direction of the mechanism bracket 10 is different from the width of the bending portion 12 along the rotation axis direction of the mechanism bracket 10. The action mechanism can reduce the size of the disconnector in the height direction.

[0033] It should be noted that, first, the action mechanism provided in the present application includes an action assembly, and the action assembly includes a mechanism bracket 10 and a connecting rod mechanism 40, such as Figure 2 and Figure 3 As shown, the mechanism bracket 10 is in transmission connection with the connecting rod mechanism 40, so that the mechanism bracket 10 is driven to rotate and can drive the connecting rod mechanism 40 to move, so that the connecting rod mechanism 40 drives the contact mechanism 400 in the body 300 of the disconnector to open or close.

[0034] It should be understood that the contact mechanism 400 of the disconnector is located inside the body 300. The present application does not limit the specific structure of the connecting rod mechanism 40 and the contact mechanism 400, and those skilled in the art can set them by themselves, as long as the mechanism bracket 10 is driven to rotate to drive the connecting rod mechanism 40 to move, so that the contact mechanism 400 located in the body 300 is opened or closed.

[0035] Second, along the rotation axis direction of the mechanism bracket 10, the orthographic projection of the action component on the body 300 partially overlaps with the body 300. Optionally, in a feasible implementation, it can be that along the rotation axis direction of the mechanism bracket 10, the orthographic projection of the mechanism bracket 10 on the body 300 partially overlaps with the body 300.

[0036] In another feasible implementation, it may be that along the rotation axis direction of the mechanism bracket 10 , the orthographic projection of the connecting rod mechanism 40 on the main body 300 partially overlaps with the main body 300 .

[0037] In another feasible implementation, it may be that along the rotation axis direction of the mechanism bracket 10 , the orthographic projections of a part of the structure of the mechanism bracket 10 and the connecting rod mechanism 40 on the body 300 partially overlap with the body 300 .

[0038] That is to say, along the rotation axis direction of the mechanism bracket 10, the present application does not limit which part of the action component has its orthographic projection on the body 300 partially overlapped with the body 300, and those skilled in the art can determine it by themselves according to actual conditions. For ease of description, the following text and the figures mainly take the example that along the rotation axis direction of the mechanism bracket 10, the orthographic projection of the connecting rod mechanism 40 on the body 300 partially overlaps with the body 300 as an example for illustration.

[0039] It should be noted that the rotation axis direction of the above-mentioned mechanism bracket 10 corresponds to Figure 2 In the orientation of the mechanism support 10, the direction perpendicular to the paper surface. In this embodiment, along the rotation axis direction of the mechanism support 10, the orthographic projection of the mechanism support 10 on the body 300 partially overlaps with the body 300. In other words, Figure 1 and Figure 2 As shown, at least a portion of the mechanism bracket 10 extends downward into the body 300 of the disconnector.

[0040] The present application extends at least a portion of the action component into the body 300 of the isolating switch, thereby reducing the overall size of the isolating switch along its height direction, facilitating the miniaturization of the isolating switch, broadening the application scenarios of the isolating switch, and improving the applicability of the isolating switch to multiple application scenarios.

[0041] Specifically, the present application does not limit the size of the action component extending into the body 300, and those skilled in the art can determine it according to actual conditions. For example, when the mechanism bracket 10 of the action component extends into the body 300, the bending portion 12 of the mechanism bracket 10 can be extended into the body 300 as a whole, or at least a portion of the bending portion 12 can be extended into the body 300. The bending portion 12 will be described in detail below.

[0042] Thirdly, the mechanism bracket 10 comprises a bracket body 11 and a bending portion 12 connected to the bracket body 11. In this embodiment, the bending portion 12 is located between the link mechanism 40 and the bracket body 11.

[0043] Also, illustratively, the above-mentioned bending portion 12 and the bracket body 11 can be connected into an integral structure, such as Figure 3 shown.

[0044] In this embodiment, along the rotation axis direction of the mechanism bracket 10, the width of the bracket body 11 and the width of the bent portion 12 are different, so that the mechanism bracket 10 has two different widths. Among them, the specific width of the bracket body 11 and the specific width of the bent portion 12 can be set by those skilled in the art according to the specific components of the isolating switch connected to the mechanism bracket 10, and this application does not make any specific restrictions.

[0045] To summarize, the action mechanism provided in the present application includes an action component, and the action component includes a mechanism bracket 10 and a connecting rod mechanism 40 that are transmission-connected; the mechanism bracket 10 is driven to rotate, and can drive the connecting rod mechanism 40 to move so that the contact mechanism 400 in the body 300 of the disconnector is opened or closed; along the rotation axis direction of the mechanism bracket 10, the positive projection of the action component on the body 300 partially overlaps with the body 300; the mechanism bracket 10 includes a bracket body 11 and a bending portion 12 connected to the bracket body 11, and the width of the bracket body 11 along the rotation axis direction of the mechanism bracket 10 is different from the width of the bending portion 12 along the rotation axis direction of the mechanism bracket 10. The action mechanism provided in the present application is configured such that the action component contained therein is partially overlapped with the main body 300 by its orthographic projection along the rotation axis direction of the mechanism bracket 10. This is equivalent to extending at least part of the action component into the main body 300 of the isolating switch. In this way, the overall volume of the isolating switch in its height direction can be compressed, thereby enabling the isolating switch to be miniaturized, broadening the application scenarios of the isolating switch, and improving the applicability of the isolating switch in various application scenarios.

[0046] Please refer to Figure 4 and Figure 5 As shown, optionally, the mechanism bracket 10 includes two symmetrically arranged mounting plates 13 and a connecting member 14 connecting the two mounting plates 13, the mounting plates 13 include a first vertical plate 131, a second vertical plate 132 and a connecting plate 133 connected between the first vertical plate 131 and the second vertical plate 132; the two connecting plates 133 and the two second vertical plates 132 form a bending portion 12, and the bending portion 12 is located in the main body 300; the two first vertical plates 131 and the connecting member 14 form a bracket body 11.

[0047] It should be noted that, first, the above-mentioned symmetrical arrangement does not mean that the two mounting plates 13 are required to be absolutely symmetrical, but there can be slight differences in the specific details of the structure. That is, the symmetrical arrangement means that they are generally symmetrical, but slight differences are allowed (for example, one mounting plate 13 is provided with a smaller protrusion, while the other mounting plate 13 is not provided with a smaller protrusion).

[0048] Second, the mechanism bracket 10 includes two symmetrically arranged mounting plates 13 and a connecting member 14 connected between the two mounting plates 13. Figure 4 Exemplarily, the mounting plate 13 includes a first vertical plate 131 , a second vertical plate 132 and a connecting plate 133 , wherein one end of the connecting plate 133 is connected to the first vertical plate 131 , and the other end is connected to the second vertical plate 132 .

[0049] The two connecting plates 133 and the two second vertical plates 132 form the above-mentioned bending portion, which is located in the body 300 (i.e., along the rotation axis direction of the mechanism bracket 10, the orthographic projection of the bending portion on the body 300 partially overlaps with the body 300). The two first vertical plates 131 and the connecting member 14 form the above-mentioned bracket body 11.

[0050] Optionally, in this embodiment, the distance between the two first vertical plates 131 is greater than the distance between the two second vertical plates 132. In this way, along the rotation axis direction of the mechanism bracket 10, the width of the bracket body 11 is different from the width of the bending portion 12, and the width of the bracket body 11 is greater than the width of the bending portion. Figure 4 and Figure 5 In the present application, the width of the bending portion 12 along the rotation axis direction of the mechanism bracket 10 is set to be smaller than the width of the bracket body 11 along the rotation axis direction of the mechanism bracket 10, so that the bending portion extending into the body 300 can occupy as little space as possible inside the body 300.

[0051] In addition, in this embodiment, Figure 4 and Figure 6 As shown, the second vertical plate 132 is provided with an arc groove 1321, and the arc groove 1321 is used to limit the rotation angle of the connecting rod mechanism 40. The setting of the arc groove 1321 can limit the rotation angle of the connecting rod mechanism 40, wherein the size and curvature of the arc groove 1321 are not limited in this application, and those skilled in the art can determine them according to their needs.

[0052] It should be noted that, for example, the connecting rod mechanism 40 can be embedded in the arc groove 1321, so that when the mechanism bracket 10 rotates, the connecting rod mechanism 40 is driven to rotate through the arc groove 1321, thereby realizing the opening or closing of the switch. For another example, the middle piece can be embedded in the arc groove 1321, and the middle piece and the connecting rod mechanism 40 are connected in transmission. In this way, when the mechanism bracket 10 rotates, the middle piece is driven to rotate through the arc groove 1321, so that the middle piece drives the connecting rod mechanism 40 to move, and the opening or closing of the connecting rod mechanism 40 can also be realized.

[0053] Exemplarily, when the arc groove 1321 drives the connecting rod mechanism 40 to move through the intermediate piece, it can be as follows: a rotating member 20 (that is, the intermediate piece mentioned above) is provided between the two second vertical plates 132, and the rotation center of the rotating member 20 is provided on the rotation axis of the two second vertical plates 132; and one end of the rotating member 20 is transmission-connected to the connecting rod mechanism 40, and the other end is provided with a pin shaft, and one end of the pin shaft extends into the arc groove 1321.

[0054] That is, the rotating member 20 is sleeved on the rotating shafts of the two second vertical plates 132 (the rotation of the rotating shafts of the two second vertical plates 132 can drive the mechanism bracket 10 to rotate), and the rotating member 20 can rotate on the rotating shafts of the two second vertical plates 132 .

[0055] In addition, one end of the rotating member 20 is in transmission connection with the connecting rod mechanism 40, and the other end is provided with a pin, and the end of the pin away from the rotating member 20 extends into the arc groove 1321. In this way, when the driving mechanism bracket 10 rotates, the mechanism bracket 10 can drive the pin located in its arc groove 1321 to move, so that the pin drives the rotating member 20 to rotate, and then the rotating member 20 drives the connecting rod mechanism 40 to move to open or close the switch, such as Figure 3 and Figure 6 shown.

[0056] like Figure 4 and Figure 5 As shown, optionally, the action mechanism further includes an energy storage member 30, which is disposed between the rotating member 20 and the second vertical plate 132. The energy storage member 30 can store energy when the mechanism bracket 10 drives the connecting rod mechanism 40 to close the switch, and can release energy when the connecting rod mechanism 40 opens the switch.

[0057] That is, when the mechanism bracket 10 rotates to drive the connecting rod mechanism 40 to close, the energy storage member 30 can store energy; when the connecting rod mechanism 40 rotates to the closing position, the energy storage member 30 completes energy storage; when the connecting rod mechanism 40 needs to open, the energy storage mechanism can release energy to enable the connecting rod mechanism 40 to open quickly. In this way, the disconnecting speed of the disconnector can be increased, and the disconnecting performance of the disconnector can be improved.

[0058] For example, Figure 4 As shown, the energy storage member 30 is an energy storage spring, and the fixed end of the energy storage spring is connected to the second vertical plate 132, and the energy storage end is connected to the rotating member 20. In this way, when the brake needs to be opened, the energy storage spring releases energy to quickly drive the rotating member 20 to rotate, so that the rotating member 20 drives the connecting rod mechanism 40 to quickly open the brake.

[0059] In this embodiment, the energy storage spring is specifically a symmetrically arranged double torsion spring (such as Figure 4), and the opposite ends of the double torsion spring (i.e. the fixed ends mentioned above) are respectively fixed on the two second vertical plates 132, and the middle end of the double torsion spring (i.e. the energy storage end mentioned above) is in contact with the rotating member 20.

[0060] In addition, if Figure 3 and Figure 4 As shown, in order to make the transmission of the connecting rod mechanism 40 more stable, in the present embodiment, one end of the two second vertical plates 132 away from the first vertical plate 131 extends in a direction away from the first vertical plate 131 to form an extension plate 134; along the rotation axis direction of the mechanism bracket 10, the orthographic projection of the extension plate 134 on the main body 300 at least covers a portion of the connecting rod mechanism 40.

[0061] That is, the extension plate 134 is formed by extending one end of the second vertical plate 132 away from the first vertical plate 131 in a direction away from the first vertical plate 131. In this embodiment, the second vertical plate 132 and the extension plate 134 are an integral part. The second vertical plate 132 is extended downward in this application so that the orthographic projection of the extension plate 134 on the body 300 covers at least part of the connecting rod mechanism 40 in the direction of the axis of the rotating rod of the mechanism bracket 10. In this way, the two symmetrically arranged extension plates 134 can restrict the connecting rod mechanism 40 between the two, thereby limiting the axial movement of the connecting rod mechanism 40 to a certain extent, thereby improving the transmission stability of the connecting rod mechanism 40.

[0062] It should be noted that, along the axis direction of the rotating rod of the mechanism bracket 10, the orthographic projection of the mounting plate 13 (including the first vertical plate 131, the connecting plate 133, the second vertical plate 132 and the extension plate 134) on the main body 300 can cover part of the connecting rod mechanism 40, or can cover the entire connecting rod mechanism 40. The present application does not impose any restrictions on this, and technicians in this field can determine it by themselves according to the actual structure.

[0063] Another aspect of the present invention provides an isolating switch, which includes an operating handle, the above-mentioned actuating mechanism, a main body 300 and a contact mechanism 400; the operating handle and the actuating mechanism are transmission-connected, the contact mechanism 400 is disposed in the main body 300 and transmission-connected to the actuating mechanism; the operating handle drives the actuating mechanism to rotate, which can drive the contact mechanism 400 in the main body 300 to open or close the switch.

[0064] The specific structures of the operating handle, the body 300 and the contact mechanism 400 are not limited in this application, and those skilled in the art can set them by themselves. As long as the operating handle can drive the action mechanism to rotate, it can drive the contact mechanism 400 in the body 300 to open or close the switch.

[0065] In this embodiment, the above-mentioned disconnector further includes an operating mechanism, one end of which is transmission-connected to the operating handle, and the other end of which is transmission-connected to the mechanism bracket 10 of the action mechanism. In this way, when opening or closing the switch, it can be realized in the following manner: the operating handle drives the operating mechanism to move, and the operating mechanism drives the mechanism bracket 10 of the action mechanism to move, so that the mechanism bracket 10 drives the connecting rod mechanism 40 to move, and the movement of the connecting rod mechanism 40 drives the contact mechanism 400 located in the body 300 to move, so that the contact mechanism 400 opens or closes the switch.

[0066] The specific structure and beneficial effects of the above-mentioned action mechanism have been described in detail in the previous text, so this application will not repeat them here.

[0067] The above description is only an optional embodiment of the present invention and is not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.

[0068] It should also be noted that the various specific technical features described in the above specific embodiments can be combined in any suitable manner without contradiction. In order to avoid unnecessary repetition, the present invention will not further describe various possible combinations.
