Description

Technical Field

[0001] The present application relates to the technical field of switch devices, and in particular to a status indicating mechanism and a switch device. Background Art

[0002] Switchgear is an essential component in electrical engineering, used to close and / or open one or more circuits and playing a critical control role in circuits. Switchgear often incorporates a status indicator to visually display the on / off status of the switch. This allows operators to quickly understand the switchgear's operating status without requiring additional testing, improving operational convenience. Furthermore, the precise display provided by the status indicator provides powerful decision support for operators, reducing the risk of misoperation and thereby improving the reliability of the entire electrical system.

[0003] However, the existing status indicating mechanism needs to occupy a large space when working, which is not conducive to the miniaturization design of the switch device. Summary of the Invention

[0004] The present application provides a status indicating mechanism and a switch device, which can save the space required by the status indicating mechanism when working, and facilitate the miniaturization design of the switch device.

[0005] In a first aspect, the present application provides a status indicator mechanism for use in a switch device, the switch device including a first state and a second state. The status indicator mechanism includes a housing, a slider-crank mechanism, a slide, and an indicator. The housing is provided with a viewing window and a sliding space, the viewing window communicating with the sliding space. The slider-crank mechanism includes a push plate. The slide is at least partially located within the sliding space and is located in the rotational path of the push plate. The indicator is connected to a side of the slide proximate the viewing window and includes a first indicator portion and a second indicator portion.

[0006] When the push plate is driven to rotate clockwise, the push plate can push the sliding plate, causing the sliding plate to slide linearly in the first direction within the sliding space. When the sliding plate slides linearly in the first direction, it can drive the indicator member to slide linearly in the first direction until the first indicating portion is opposite to the window, so that the indicator member indicates that the switch device is in the first state.

[0007] When the push plate is driven to rotate counterclockwise, the push plate releases its resistance to the sliding plate, allowing the sliding plate to slide linearly in the second direction within the sliding space. When the sliding plate slides linearly in the second direction, it drives the indicator member to slide linearly in the second direction until the second indicator portion faces the window, so that the indicator member indicates that the switch device is in the second state.

[0008] The first direction is opposite to the second direction, and one of the first state and the second state is a closed state, and the other is an open state.

[0009] Through the above solution, the slide plate is located in the sliding space of the housing and is located on the rotation path of the push plate. The indicator is connected to the side of the slide plate close to the window, so when the push plate is driven to rotate, it can push the slide plate, causing the slide plate to slide in the sliding space, thereby driving the indicator to slide in the sliding space. The sliding space can limit the sliding of the slide plate. When the push plate pushes the slide plate, the slide plate and the indicator can slide along a straight line. It can be seen that the present application converts the rotation of the push plate into linear sliding of the slide plate and the indicator through the cooperation of the push plate and the slide plate, so that the indicator can indicate different states of the switch device by linear sliding. The indicator of the present application can indicate different states of the switch device by linear sliding. The space required for linear sliding is smaller than that for rotation. Therefore, compared with the prior art, the present application does not need to reserve a large space for the action of the indicator, which facilitates the miniaturization of the switch device.

[0010] In one possible design, the slider-crank mechanism further includes a rotating shaft, a guide rod, and a fixed shaft. The rotating shaft is rotatably connected to the housing, and the fixed shaft is fixed to the housing. The first end of the guide rod is rotatably connected to the rotating shaft, and the second end of the guide rod is provided with a strip groove, through which the second end is sleeved on the fixed shaft. The push plate is connected to the guide rod.

[0011] When the rotating shaft is driven counterclockwise, the guide rod rotates clockwise relative to the fixed shaft, and the strip groove moves relative to the fixed shaft. When the guide rod rotates clockwise relative to the fixed shaft, the push plate rotates clockwise with the guide rod, pushing the sliding plate to slide in the first direction. When the rotating shaft is driven clockwise, the guide rod rotates counterclockwise relative to the fixed shaft, and the strip groove moves relative to the fixed shaft. When the guide rod rotates counterclockwise relative to the fixed shaft, the push plate rotates counterclockwise with the guide rod, releasing the push force on the sliding plate.

[0012] Through the above scheme, when the rotating shaft in the crank slider mechanism rotates, it can drive the guide rod to rotate relative to the fixed shaft and drive the strip groove on the guide rod to move relative to the fixed shaft. When the guide rod rotates, it can drive the push plate to rotate, thereby resisting the sliding of the sliding plate, or releasing the resistance to the sliding plate to reset the sliding plate. As can be seen, the present application, through the coordination of the rotating shaft, guide rod, push plate, fixed shaft, and sliding plate, converts the rotation of the rotating shaft through the transition of the guide rod, push plate, and fixed shaft to the linear sliding of the sliding plate and the indicator member, so that the indicator member can indicate different states of the switch device through linear sliding.

[0013] In one possible design, the slider-crank mechanism further includes a first elastic member. The first elastic member and a push plate are both sleeved on the guide rod, with the push plate positioned between the first elastic member and the fixed shaft. The first end of the first elastic member abuts the guide rod, the second end of the first elastic member abuts the push plate, and the push plate also abuts the fixed shaft.

[0014] By setting the first elastic member, power can be provided for the guide rod to rotate with the rotating shaft. On the one hand, it is convenient to save the driving force when the rotating shaft drives the guide rod to rotate. On the other hand, it is convenient for the switch device to smoothly pass the dead point position and quickly switch to the open position or the closed position, thereby improving the efficiency of the switch device in opening or closing.

[0015] In a possible design, the status indicating mechanism further includes a second elastic member, a first end of the second elastic member abuts against the housing, and a second end of the second elastic member abuts against a side of the slide plate facing away from the push plate.

[0016] By providing a second elastic member, power can be provided for the slide to drive the indicator member to slide in the direction close to the rotating shaft, ensuring that when the switch device is in the second state, the slide can drive the indicator member to slide until the second indicating portion of the indicator member is opposite to the window, so that the indicator member can accurately indicate that the switch device is in the second state.

[0017] In a possible design, the shell includes a first shell and a second shell covering each other, the first shell and / or the second shell is provided with a first limit plate and a second limit plate, and the sliding space is formed between the first limit plate and the second limit plate.

[0018] By arranging the first limiting plate and the second limiting plate on the first shell and / or the second shell, a sliding space for the slide plate to slide can be formed between the first limiting plate and the second limiting plate, so that the slide plate can slide linearly in the sliding space.

[0019] In a possible design, the slide includes a first side close to the first limiting plate and a second side close to the second limiting plate, the first side contacts the first limiting plate, and the second side contacts the second limiting plate.

[0020] With the above solution, the first limiting plate can provide guidance and positioning for the first side of the skateboard during the sliding process, facilitating the sliding of the first side of the skateboard along the first limiting plate. The second limiting plate can also provide guidance and positioning for the second side of the skateboard during the sliding process, facilitating the sliding of the second side of the skateboard along the second limiting plate. In this way, the skateboard can slide linearly within the sliding space under the guidance and positioning of the first and second limiting plates.

[0021] In one possible design, in the direction in which the first and second shells are aligned, one side of the first limiting plate abuts the first shell, and the other side of the first limiting plate abuts the second shell. And / or, in the direction in which the first and second shells are aligned, one side of the second limiting plate abuts the first shell, and the other side of the second limiting plate abuts the second shell.

[0022] With the above solution, the first limiting plate can provide guidance and limit for the sliding of the slide plate between the side close to the first shell and the side close to the second shell, facilitating the slide plate to slide linearly within the sliding space. The second limiting plate can provide guidance and limit for the sliding of the slide plate between the side close to the first shell and the side close to the second shell, facilitating the slide plate to slide linearly within the sliding space.

[0023] In a possible design, one of the indicator member and the slide plate is provided with a slot, and the other of the indicator member and the slide plate is provided with an inserting strip, which cooperates with the slot to connect the indicator member to the slide plate.

[0024] The indicator and the slide are connected by matching the inserting strips and the slots, which has a simple structure and low installation difficulty, and is convenient for improving the assembly efficiency of the indicator and the slide.

[0025] In one possible design, the housing further includes an outer cover that covers the side of the second housing facing away from the first housing, and a viewing window is provided in the outer cover. The side of the second housing facing away from the first housing includes a first portion and a second portion, the second portion being an edge portion of the side of the second housing facing away from the first housing. The status indicator mechanism further includes an electric mechanism mounted on the first portion. The second portion is provided with a retaining groove, along which the slide plate and / or indicator member slide.

[0026] By installing the electric mechanism in a first portion of the second housing on the side facing away from the first housing, and providing the retaining groove in a second portion of the second housing, the retaining groove only occupies a small space at the edge of the second housing, since the second portion is located at the edge of the second housing on the side facing away from the first housing. This does not occupy the area of ​​the second housing where the electric mechanism is installed. As a result, when the slide and / or indicator slide along the retaining groove, they will not interfere with the electric mechanism installed on the second housing.

[0027] In a second aspect, the present application provides a switch device comprising the status indicating mechanism in the first aspect.

[0028] The beneficial effects of the switch device provided in the above-mentioned second aspect and each possible design of the above-mentioned second aspect can be referred to the beneficial effects brought about by the above-mentioned first aspect and each possible implementation method of the first aspect, and will not be repeated here.

[0047] To make the purpose, technical solutions, and advantages of the embodiments of this application more clear, the technical solutions in the embodiments of this application will be clearly and completely described below in conjunction with the drawings in the embodiments of this application. Obviously, the described embodiments are part of the embodiments of this application, not all of the embodiments.

[0049] References to "embodiments" herein mean that a particular feature, structure, or characteristic described in connection with the embodiments may be included in at least one embodiment of the present application. The appearance of the phrase "embodiment" in various places in the specification does not necessarily refer to the same embodiment, nor does it necessarily refer to independent or alternative embodiments that are mutually exclusive of other embodiments. It is understood, both explicitly and implicitly, by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0050] The term "and / or" in this document simply describes a relationship between related objects, indicating that three possible relationships exist. For example, "A and / or B" can mean: A exists, A and B exist, and B exists. Additionally, the character " / " in this document generally indicates that the related objects are in an "or" relationship.

[0055] Figure 1 This is an exploded diagram of a state indication mechanism provided in an embodiment of the present application. The switch device provided in the present application includes an operating mechanism, a moving contact, a stationary contact, and Figure 1 The status indicating mechanism 100 is shown.

[0056] like Figure 1 As shown, the state indicating mechanism 100 includes a rotating shaft 121. The rotating shaft 121 is fixedly connected to the operating mechanism, and the operating mechanism is fixedly connected to the moving contact. Figure 1 Taking the illustrated orientation as an example, when the rotating shaft 121 is driven to rotate clockwise, the operating mechanism drives the moving contact clockwise, causing the moving contact to separate from or contact the stationary contact. Conversely, when the rotating shaft 121 is driven to rotate counterclockwise, the operating mechanism drives the moving contact counterclockwise, causing the moving contact to contact or separate from the stationary contact. This application does not limit the correspondence between the rotation direction of the moving contact and the contact or separation of the moving and stationary contacts.

[0057] Among them, assuming that the moving contact can contact the static contact when rotating counterclockwise, then the moving contact can separate from the static contact when rotating clockwise. Similarly, assuming that the moving contact can separate from the static contact when rotating counterclockwise, then the moving contact can contact the static contact when rotating clockwise.

[0058] When the moving contact contacts the stationary contact, the switch device is in the closed state. When the moving contact separates from the stationary contact, the switch device is in the open state. For ease of description, this application refers to one of the closed and open states as the first state, and the other of the closed and open states as the second state. The first state can refer to either the closed state or the open state, and the second state can refer to either the open state or the closed state, and this application does not limit this.

[0059] The switch device provided in this application can be a rotary switch or other switch product with status indication requirements, and this application does not limit this.

[0060] The status indicating mechanism 100 provided in the present application requires only a small space when in operation, thereby facilitating a miniaturized design of the switch device including the status indicating mechanism 100 .

[0061] In order to enable those skilled in the art to better understand the present application, the status indication mechanism in the embodiment of the present application will be clearly and completely described below with reference to the accompanying drawings.

[0062] Figure 2 This is an exploded view of a crank slider mechanism provided in an embodiment of the present application, such as Figure 1 and Figure 2 As shown, the status indicator mechanism 100 includes a housing 110, a slider-crank mechanism 120, a slide 130, and an indicator 140. The housing 110 is provided with a viewing window 111 and a sliding space, with the viewing window 111 communicating with the sliding space. The slider-crank mechanism 120 includes a push plate 122. The slide 130 is at least partially located within the sliding space and is located along the rotational path of the push plate 122. The indicator 140 is connected to a side of the slide 130 near the viewing window 111 and includes a first indicator portion and a second indicator portion.

[0063] like Figure 1 As shown, the housing 110 may include multiple parts, and components such as the crank slider mechanism 120 and the slide plate 130 are all located inside the housing 110 to protect the internal components.

[0064] The window 111 can be a through hole provided on the shell 110 . The shape of the through hole can be square, circular, etc., as long as it can be connected to the sliding space inside the shell 110 . This application does not limit the structure of the window 111 .

[0065] The sliding space is the space where the skateboard 130 is located, and the sliding space is generally in the shape of a cuboid or a cube. The skateboard 130 is at least partially located within the sliding space, and the sliding space can limit the movement of the skateboard 130, causing the skateboard 130 to slide along a fixed route. In this application, under the limitation of the sliding space, the skateboard 130 slides basically in a straight line. That is to say, in this application, the skateboard 130 makes a straight-line slide rather than an arc slide.

[0066] As Figure 1 and Figure 2 shown, the crank-slider mechanism 120 includes a push plate 122. The push plate 122 can rotate when the crank-slider mechanism 120 operates. The skateboard 130 is located on the rotation path of the push plate 122, so the push plate 122 can push against the skateboard 130 when rotating, causing the skateboard 130 to slide within the sliding space.

[0067] The indicating member 140 can be connected to the side of the skateboard 130 close to the window 111 by any means such as plugging, clamping, screw connection, etc. The side of the indicating member 140 facing the window 111 includes a first indicating portion and a second indicating portion. The first indicating portion and the second indicating portion correspond to different parts on the side of the indicating member 140 facing the window 111. Different indicating marks can be provided on the first indicating portion and the second indicating portion, so that the operator can distinguish the state of the switch device according to the indicating marks.

[0068] Exemplarily, the indicating marks on the first indicating portion and the second indicating portion can be the numbers 0 and 1 respectively, or can be the Chinese characters "closed" and "open" respectively, or can be a red indicator light and a green indicator light respectively. This application does not limit the specific form of the indicating marks.

[0069] The working principle of the state indicating mechanism 100 provided by this application is as follows: As Figure 3 and Figure 4 shown in the placement orientation, when the push plate 122 is driven to rotate clockwise, that is, when rotating from the state shown in Figure 3 to the state shown in Figure 4 the push plate 122 can push against the skateboard 130, causing the skateboard 130 to slide linearly in the first direction within the sliding space. When the skateboard 130 slides linearly in the first direction, it can drive the indicating member 140 to slide linearly in the first direction until the first indicating portion faces the window 111, so that the indicating member 140 indicates that the switch device is in the first state.

[0070] Continuing with the placement orientation shown in Figure 3 and Figure 4 when the push plate 122 is driven to rotate counterclockwise, that is, when rotating from the state shown in Figure 4 to the state shown in Figure 3In the illustrated state, the push plate 122 releases its resistance to the slide plate 130, allowing the slide plate 130 to slide linearly in the second direction within the sliding space. The linear sliding of the slide plate 130 in the second direction drives the indicator 140 to slide linearly in the second direction until the second indicator portion faces the window 111, thereby causing the indicator 140 to indicate that the switch device is in the second state.

[0071] The first direction is opposite to the second direction, and one of the first state and the second state is a closed state, and the other is an open state.

[0072] The status indicator 100 is Figure 3 and Figure 4 When placed in the shown orientation, the slider 130 sliding linearly in the first direction in the sliding space can be understood as the slider 130 sliding linearly toward the left in the sliding space, and the slider 130 sliding linearly in the second direction in the sliding space can be understood as the slider 130 sliding linearly toward the right in the sliding space.

[0073] In the state indicating mechanism 100 provided in the embodiment of the present application, the slide 130 is located in the sliding space of the housing 110 and on the rotation path of the push plate 122. The indicator 140 is connected to the side of the slide 130 near the window 111. Therefore, when the push plate 122 is driven to rotate, it can push against the slide 130, causing the slide 130 to slide in the sliding space, thereby driving the indicator 140 to slide in the sliding space. The sliding space can limit the sliding of the slide 130. When the push plate 122 pushes against the slide 130, the slide 130 and the indicator 140 can slide along a straight line. It can be seen that the present application converts the rotation of the push plate 122 into the linear sliding of the slide 130 and the indicator 140 through the cooperation between the push plate 122 and the slide 130, so that the indicator 140 can indicate different states of the switch device through linear sliding.

[0074] When the push plate 122 is driven to rotate clockwise, it pushes the slide plate 130 against the push plate 130, causing it to slide linearly in a first direction within the sliding space. The indicator member 140 slides linearly with the slide plate 130 in the first direction until the first indicator portion faces the window 111, thereby indicating that the switch device is in the first state. Conversely, when the push plate 122 is driven to rotate counterclockwise, the push plate 122 no longer pushes against the slide plate 130. The slide plate 130 drives the indicator member 140 to slide in the second direction until the second indicator portion of the indicator member 140 faces the window 111, thereby indicating that the switch device is in the second state.

[0075] In the related art, when the indicator component rotates with the rotating shaft to the closed position, the indicator component indicates that the switch device is in the closed state. When the indicator component rotates with the rotating shaft to the open position, the indicator component indicates that the switch device is in the open state. As can be seen, the rotation amplitude of the indicator component in the related art is the same as the rotation amplitude of the rotating shaft. This requires a large space to rotate the indicator component, which is not conducive to the miniaturization design of the switch device.

[0076] However, the indicator 140 of the present application can indicate different states of the switch device by linear sliding. The space required for linear sliding is smaller than that for rotation. Therefore, compared with the prior art, the present application does not need to reserve a large space for the movement of the indicator 140, which facilitates the miniaturization design of the switch device.

[0077] Please continue to refer to Figures 1 to 4 In some embodiments, in addition to the aforementioned rotating shaft 121, the slider-crank mechanism 120 may also include a guide rod 123 and a fixed shaft 124. The rotating shaft 121 is rotatably connected to the housing 110, and the fixed shaft 124 is fixed to the housing 110. The first end of the guide rod 123 is rotatably connected to the rotating shaft 121. The second end of the guide rod 123 is defined by a strip groove 1231, and the second end is sleeved on the fixed shaft 124 through the strip groove 1231. The push plate 122 is connected to the guide rod 123.

[0078] like Figure 1 and Figure 5 As shown, the shell 110 may include a first shell 112 and a second shell 113 that cover each other. The first shell 112 may be provided with a first through hole 1121, and the second shell 113 may be provided with a second through hole 1131. The rotating shaft 121 is located between the first shell 112 and the second shell 113. One end of the rotating shaft 121 cooperates with the first through hole 1121, and the other end of the rotating shaft 121 cooperates with the second through hole 1131 to realize the rotational connection of the rotating shaft 121 on the shell 110.

[0079] The fixed shaft 124 can be fixed between the first shell 112 and the second shell 113 by means of plugging, abutting, etc. The fixed shaft 124 can be fixedly connected to only one of the first shell 112 and the second shell 113, or can be fixedly connected to both the first shell 112 and the second shell 113, which is not limited in this application.

[0080] like Figure 2As shown, the rotating shaft 121 is provided with a support shaft 1211, which is provided with a support groove C1. The first end of the guide rod 123 is provided with a U-shaped notch. The U-shaped notch is engaged with the support groove C1. With the cooperation between the U-shaped notch and the support groove C1, the guide rod 123 can rotate with the rotating shaft 121. The guide rod 123 can also rotate relative to the rotating shaft 121, thereby achieving a rotational connection between the first end of the guide rod 123 and the rotating shaft 121.

[0081] Alternatively, the rotating shaft 121 is provided with a support shaft 1211, and the first end of the guide rod 123 is provided with a waist-shaped groove, and the support shaft 1211 is inserted into the waist-shaped groove. In this way, the first end of the guide rod 123 can also be rotatably connected to the rotating shaft 121. This application is not limited to this.

[0082] Please continue to refer to Figure 2 The second end of the guide rod 123 is provided with a strip groove 1231, and the fixed shaft 124 is inserted into the strip groove 1231 to connect the second end of the guide rod 123 to the fixed shaft 124. The second end of the guide rod 123 can rotate relative to the fixed shaft 124 and can also move relative to the fixed shaft 124 on the line connecting the fixed shaft 124 and the support shaft 1211. The width of the strip groove 1231 can be slightly larger than the diameter of the fixed shaft 124. This ensures that the fixed shaft 124 fits neatly within the strip groove 1231 while reducing the possibility of unpredictable shaking of the second end of the guide rod 123 when rotating or moving relative to the fixed shaft 124.

[0083] The length of the strip groove 1231 can be set as needed. Assuming that the groove wall of the strip groove 1231 that is closer to the rotating shaft 121 along its length is called the first groove wall, and the groove wall of the strip groove 1231 that is farther from the rotating shaft 121 along its length is called the second groove wall, the length of the strip groove 1231 can be set according to the following principle: when the switch device is in the closed position and the open position, the side wall of the fixed shaft 124 abuts the second groove wall. When the switch device is in the dead point position, the side wall of the fixed shaft 124 abuts the first groove wall. The dead point position is located between the closed position and the open position. When in the dead point position, the switch device is between the first state and the second state.

[0084] Based on this, when the switch device rotates from the closed position or the open position to the dead point position, the second end of the guide rod 123 or the strip groove 1231 moves relative to the fixed shaft 124 in a direction away from the rotating shaft 121. When the switch device switches from the dead point position to the open position or the closed position, the second end of the guide rod 123 or the strip groove 1231 rotates relative to the fixed shaft 124 in a direction toward the rotating shaft 121.

[0085] The push plate 122 can be fixedly connected to the guide rod 123 by welding, screw connection, etc., or can be movably connected to the guide rod 123, which is not limited in this application. Figure 2 As shown, the push plate 122 is provided with a through slot 1221 , and the push plate 122 is sleeved on the guide rod 123 through the through slot 1221 , so that the push plate 122 and the guide rod 123 can be movably connected.

[0086] When the push plate 122 is fixedly connected to the guide rod 123, the push plate 122 can only rotate with the guide rod 123. When the push plate 122 is movably connected to the guide rod 123, the push plate 122 can not only rotate with the guide rod 123, but also slide relative to the guide rod 123.

[0087] The operating principle of the slider-crank mechanism 120 in the present application is as follows: when the rotating shaft 121 is driven to rotate counterclockwise, the guide rod 123 rotates clockwise relative to the fixed shaft 124, and the strip groove 1231 moves relative to the fixed shaft 124. When the guide rod 123 rotates clockwise relative to the fixed shaft 124, the push plate 122 rotates clockwise along with the guide rod 123, pushing the slide plate 130 and the indicator 140 to slide in the first direction.

[0088] When the rotating shaft 121 is driven to rotate clockwise, the guide rod 123 rotates counterclockwise relative to the fixed shaft 124, and the strip groove 1231 moves relative to the fixed shaft 124. When the guide rod 123 rotates counterclockwise relative to the fixed shaft 124, the push plate 122 rotates counterclockwise along with the guide rod 123, releasing the push against the slide plate 130, allowing the slide plate 130 and the indicator 140 to slide in the second direction.

[0089] According to the solution of this embodiment, when the rotating shaft 121 in the slider-crank mechanism 120 rotates, it can drive the guide rod 123 to rotate relative to the fixed shaft 124 and drive the strip groove 1231 on the guide rod 123 to move relative to the fixed shaft 124. When the guide rod 123 rotates, it can drive the push plate 122 to rotate, thereby pushing the slide plate 130 to slide, or releasing the push on the slide plate 130 to reset the slide plate 130. It can be seen that the present application, through the cooperation of the rotating shaft 121, the guide rod 123, the push plate 122, the fixed shaft 124, and the slide plate 130, converts the rotation of the rotating shaft 121 into linear sliding of the slide plate 130 and the indicator 140 through the transition of the guide rod 123, the push plate 122, and the fixed shaft 124, so that the indicator 140 can indicate different states of the switch device through linear sliding.

[0090] Please continue to refer to Figures 1 to 4Furthermore, the slider-crank mechanism 120 may further include a first elastic member 150. The first elastic member 150 and the push plate 122 are both sleeved on the guide rod 123, and the push plate 122 is located between the first elastic member 150 and the fixed shaft 124. The first end of the first elastic member 150 abuts against the guide rod 123, and the second end of the first elastic member 150 abuts against the push plate 122. The push plate 122 also abuts against the fixed shaft 124.

[0091] The first elastic member 150 can be a spring. Alternatively, the first elastic member 150 can be a compression spring. Thus, when the first elastic member 150 is sleeved on the guide rod 123, the first end of the first elastic member 150 can always abut against the guide rod 123, and the second end can always abut against the push plate 122, thereby reducing the possibility of unnecessary shaking of the push plate 122 on the guide rod 123.

[0092] like Figure 2 As shown, the first end of the guide rod 123 can be provided with a limiting shoulder 1232. After the first elastic member 150 is sleeved on the guide rod 123 from the second end of the guide rod 123, the first end of the first elastic member 150 abuts against the limiting shoulder 1232 of the guide rod 123.

[0093] The second end of the first elastic member 150 abuts against the side of the push plate 122 facing the first elastic member 150, and the side of the push plate 122 facing away from the first elastic member 150 abuts against the fixed shaft 124. Thus, the first elastic member 150 and the push plate 122 are constrained between the fixed shaft 124 and the limiting shoulder 1232, and subsequent movement of both occurs between the fixed shaft 124 and the limiting shoulder 1232.

[0094] In this embodiment, the first elastic member 150 and the push plate 122 are sleeved on the guide rod 123. When the switch device is in the closed or open position, the side wall of the fixed shaft 124 abuts the second wall of the strip groove 1231, and the first elastic member 150 is in its original extended state. As the strip groove 1231 moves away from the rotating shaft 121 relative to the fixed shaft 124, the first elastic member 150 is gradually compressed and stores energy. When the switch device switches from the closed or open position to the dead center, the side wall of the fixed shaft 124 abuts the first wall of the strip groove 1231, and the first elastic member 150 reaches its maximum compression.

[0095] Afterwards, the strip groove 1231 moves relative to the fixed shaft 124 toward the rotating shaft 121, and the first elastic member 150 releases energy, pushing the guide rod 123 so that the guide rod 123 rotates rapidly along with the rotating shaft 121 until the switching device switches from the dead point position to the open position or the closed position, and the side wall of the fixed shaft 124 again abuts against the second groove wall of the strip groove 1231, and the first elastic member 150 returns to its original extended state.

[0096] It can be seen that the setting of the first elastic member 150 can provide power for the guide rod 123 to rotate with the rotating shaft 121. On the one hand, it is convenient to save the driving force when the rotating shaft 121 drives the guide rod 123 to rotate. On the other hand, it is convenient for the switching device to smoothly pass the dead point position and quickly switch to the open position or the closed position, thereby improving the opening or closing efficiency of the switching device.

[0097] Please continue to refer to Figure 1 、 Figure 3 and Figure 4 In some embodiments, the state indicating mechanism 100 may further include a second elastic member 160 . A first end of the second elastic member 160 abuts against the housing 110 , and a second end of the second elastic member 160 abuts against a side of the slide plate 130 facing away from the push plate 122 .

[0098] The first end of the second elastic member 160 may abut only one of the first shell 112 and the second shell 113 , or may partially abut the first shell 112 and partially abut the second shell 113 as shown in the drawings of this application. This application does not limit this.

[0099] by Figure 1 、 Figures 3 to 5 For example, the first housing 112 may be provided with a first extension 1122, which extends away from the rotation axis 121 relative to the outer wall of the first housing 112. The second housing 113 may be provided with a second extension, which extends away from the rotation axis 121 relative to the outer wall of the second housing 113. A first receiving groove C2 may be provided on the side of the first extension 1122 facing the second extension, and a second receiving groove may be provided on the side of the second extension facing the first extension 1122. The notch of the first receiving groove C2 is opposite to the notch of the second receiving groove. The cross-sectional shape of the first receiving groove C2 and the second receiving groove may be semicircular, rectangular, etc.

[0100] The portion of the second elastic member 160 near the first housing 112 is located within the first receiving groove C2, and the portion of the second elastic member 160 near the second housing 113 is located within the second receiving groove. Therefore, the first end of the second elastic member 160 abutting against the housing 110 means that the portion of the first end of the second elastic member 160 near the first housing 112 abuts against the wall of the first receiving groove C2, and the portion of the first end of the second elastic member 160 near the second housing 113 abuts against the wall of the second receiving groove.

[0101] Optionally, the portion of the shell 110 that is used to abut against the first end of the second elastic member 160 can be provided with a first protrusion or a first groove, and the first end of the second elastic member 160 can be sleeved on the first protrusion or embedded in the first groove to reduce the problem of abutment failure such as slipping when the first end of the second elastic member 160 abuts against the shell 110.

[0102] Similarly, a second boss or a second groove can be provided on the side of the slide plate 130 facing away from the push plate 122, and the second end of the second elastic member 160 can be sleeved on the second boss or embedded in the second groove to reduce the problem of abutment failure such as slipping when the second end of the second elastic member 160 abuts against the side of the slide plate 130 facing away from the push plate 122.

[0103] like Figure 1 and Figure 6 As shown, a position corresponding to the sliding space of the second housing 113 may be provided with a retaining groove 1133. The slide plate 130 and / or the indicator 140 may be inserted into the retaining groove 1133. When the switch device is in the first state, the slide plate 130 and / or the indicator 140 abut against the wall of the retaining groove 1133 away from the rotating shaft 121. When the switch device is in the second state, the slide plate 130 and / or the indicator 140 abut against the wall of the retaining groove 1133 closer to the rotating shaft 121.

[0104] The second elastic member 160 can be a spring. Optionally, the second elastic member 160 can be a compression spring. Thus, when the first end of the second elastic member 160 abuts against the housing 110 and the second end abuts against the side of the slide 130 facing away from the push plate 122, assuming that the push plate 122 does not push against the slide 130, the slide 130 can abut against the groove wall of the limiting groove 1133 near the rotating shaft 121 under the elastic force of the second elastic member 160. This can help reduce the possibility of unnecessary shaking of the second elastic member 160 and the slide 130 within the sliding space, thereby facilitating the positioning of the indicator 140 in a fixed position to accurately indicate the second state of the switch device.

[0105] In this embodiment, the first end of the second elastic member 160 abuts the housing 110, and the second end abuts the side of the slide plate 130 facing away from the push plate 122. When the switch device is in the second state, the push plate 122 does not abut the slide plate 130, and the second elastic member 160 is in its original extended state. As the switch device switches from the second state to the first state, the push plate 122 abuts the slide plate 130, causing the slide plate 130 to slide the indicator member 140 in the first direction. The second elastic member 160 is gradually compressed to store energy until it reaches its maximum compression when the switch device is in the first state.

[0106] Thereafter, when the switch device switches from the first state to the second state, the push plate 122 releases its resistance to the slide plate 130, and the second elastic member 160 releases energy, pushing the slide plate 130 to slide toward the rotation axis 121. When the switch device is in the second state, the second elastic member 160 returns to its original extended state.

[0107] It can be seen that the setting of the second elastic member 160 can provide power for the slide plate 130 to drive the indicator member 140 to slide in the direction close to the rotating shaft 121, ensuring that when the switch device is in the second state, the slide plate 130 can drive the indicator member 140 to slide until the second indicating portion of the indicator member 140 is opposite to the window 111, so that the indicator member 140 can accurately indicate that the switch device is in the second state.

[0108] Please continue to refer to Figure 1 and Figure 5 The first shell 112 and / or the second shell 113 is provided with a first limiting plate 114 and a second limiting plate 115 , and a sliding space is formed between the first limiting plate 114 and the second limiting plate 115 .

[0109] The first and second limiting plates 114, 115 are positioned opposite each other and spaced apart. The first and second limiting plates 114, 115 may be parallel to each other, and a sliding space for the slide plate 130 is formed between the first and second limiting plates 114, 115. The structures of the first and second limiting plates 114, 115 may be the same or different, and this application does not limit this.

[0110] In a first possible configuration, the first limiting plate 114 and the second limiting plate 115 are both provided on the first housing 112 . In other words, only the first housing 112 is provided with the first limiting plate 114 and the second limiting plate 115 .

[0111] In a second possible configuration, the first limiting plate 114 and the second limiting plate 115 are both provided on the second housing 113. In other words, only the second housing 113 is provided with the first limiting plate 114 and the second limiting plate 115.

[0112] In a third possible configuration, one of the first limiting plate 114 and the second limiting plate 115 is disposed on the first shell 112 , and the other of the first limiting plate 114 and the second limiting plate 115 is disposed on the second shell 113 .

[0113] In a fourth possible configuration, the first limiting plate 114 and the second limiting plate 115 are provided on both the first housing 112 and the second housing 113. In other words, the first housing 112 and the second housing 113 are both provided with the first limiting plate 114 and the second limiting plate 115.

[0114] Regardless of how the first limiting plate 114 and the second limiting plate 115 are disposed on the first shell 112 and / or the second shell 113 , a sliding space can be formed between the first limiting plate 114 and the second limiting plate 115 .

[0115] Optionally, in the arrangement direction of the first shell 112 and the second shell 113, the side of the first limiting plate 114 close to the first shell 112 can abut against the first shell 112, and the side of the first limiting plate 114 close to the second shell 113 can abut against the second shell 113. In this way, the first limiting plate 114 can provide guidance and limit the sliding of the slide plate 130 from the side close to the first shell 112 to the side close to the second shell 113, thereby facilitating the slide plate 130 to slide linearly within the sliding space.

[0116] And / or, in the arrangement direction of the first shell 112 and the second shell 113, the side of the second limiting plate 115 close to the first shell 112 can abut against the first shell 112, and the side of the second limiting plate 115 close to the second shell 113 can abut against the second shell 113. In this way, the second limiting plate 115 can provide guidance and limit the sliding of the slide plate 130 from the side close to the first shell 112 to the side close to the second shell 113, thereby facilitating the slide plate 130 to slide linearly within the sliding space.

[0117] In this embodiment, a first limiting plate 114 and a second limiting plate 115 are provided on the first shell 112 and / or the second shell 113, and a sliding space for the slide plate 130 to slide can be formed between the first limiting plate 114 and the second limiting plate 115, so that the slide plate 130 can slide linearly in the sliding space.

[0118] Furthermore, the slide plate 130 includes a first side close to the first limiting plate 114 and a second side close to the second limiting plate 115 . The first side contacts the first limiting plate 114 , and the second side contacts the second limiting plate 115 .

[0119] With this arrangement, the first limiting plate 114 can provide guidance and position limiting for the first side of the slide plate 130 during the sliding process of the slide plate 130, facilitating the sliding of the first side of the slide plate 130 along the first limiting plate 114. The second limiting plate 115 can also provide guidance and position limiting for the second side of the slide plate 130 during the sliding process of the slide plate 130, facilitating the sliding of the second side of the slide plate 130 along the second limiting plate 115. In this manner, the slide plate 130 can slide linearly within the sliding space under the guidance and position limiting of the first limiting plate 114 and the second limiting plate 115.

[0120] Optional, such as Figure 1 、 Figure 5 and Figure 7As shown, a first notch 131 can be provided in the middle portion of the first side of the skateboard 130 to ensure that the first limiting plate 114 is in contact with the first side of the skateboard 130 on both the side close to the first shell 112 and the side close to the second shell 113, so as to provide guidance and limitation for the sliding of the skateboard 130, thereby reducing the contact area between the first side of the skateboard 130 and the first limiting plate 114, thereby reducing the sliding friction between the skateboard 130 and the first limiting plate 114 when sliding, reducing the sliding resistance of the skateboard 130 and the wear on the skateboard 130.

[0121] The middle portion of the first side of the slide plate 130 refers to the remaining portion of the first side of the slide plate 130 except the portion close to the first shell 112 and the portion close to the second shell 113 .

[0122] Similar, please continue to refer to Figure 1 、 Figure 5 and Figure 7 A second notch 132 can be provided in the middle part of the second side of the skateboard 130 to ensure that the second limiting plate 115 is in contact with the second side of the skateboard 130 on both the side close to the first shell 112 and the side close to the second shell 113, so as to provide guidance and limitation for the sliding of the skateboard 130, thereby reducing the contact area between the second side of the skateboard 130 and the second limiting plate 115, thereby reducing the sliding friction between the skateboard 130 and the second limiting plate 115 when sliding, reducing the sliding resistance of the skateboard 130 and the wear on the skateboard 130.

[0123] The middle portion of the second side of the slide plate 130 refers to the remaining portion of the second side of the slide plate 130 except the portion close to the first shell 112 and the portion close to the second shell 113 .

[0124] In some embodiments, as Figure 7 As shown, one of the indicator member 140 and the slide 130 may be provided with a slot 141, and the other of the indicator member 140 and the slide 130 may be provided with an insert 133. The insert 133 cooperates with the slot 141 to connect the indicator member 140 to the slide 130. The connection between the insert 133 and the slot 141 is simple in structure, easy to install, and convenient for improving the assembly efficiency of the indicator member 140 and the slide 130.

[0125] Figure 7 As shown in FIG, an inserting strip 133 is provided at one end of the slide plate 130 close to the indicator 140 , and a slot 141 is provided at one end of the indicator 140 close to the slide plate 130 .

[0126] Specifically, if Figure 7As shown, the slide 130 includes a first horizontal plate 134 and a second horizontal plate 135 that are positioned opposite and spaced apart, and the slide 130 also includes a vertical plate 136 that is located between the first horizontal plate 134 and the second horizontal plate 135 and connected to the first horizontal plate 134 and the second horizontal plate 135 at both ends. Figure 1 、 Figure 2 and Figure 7 As shown, when the push plate 122 pushes the slide plate 130, the push plate 122 is located in the space defined by the first horizontal plate 134, the vertical plate 136 and the second horizontal plate 135. The vertical plate 136 serves as a force-bearing surface and abuts against the push plate 122, and the first horizontal plate 134 and the second horizontal plate 135 serve as limiting surfaces of the push plate 122 and abut against the push plate 122.

[0127] Based on this, the insertion strip 133 can be provided on the side of the first transverse plate 134 facing away from the vertical plate 136. In this way, when the insertion strip 133 is installed in conjunction with the slot 141, the first transverse plate 134 can also provide a limiting surface or support surface for the installation of the indicator 140 on the slide 130, thereby facilitating the fixing of the indicator 140 relative to the slide 130.

[0128] like Figure 8 and Figure 9 As shown, in some embodiments, the housing 110 may further include an outer cover 116, which covers the side of the second housing 113 facing away from the first housing 112, and the window 111 is provided on the outer cover 116. The side of the second housing 113 facing away from the first housing 112 includes a first portion and a second portion, the second portion being an edge portion of the side of the second housing 113 facing away from the first housing 112, as shown in FIG. Figure 6 As shown, the state indicating mechanism 100 further includes an electric mechanism 170 , which is installed at the first portion. A limiting groove 1133 is provided at the second portion, along which the slide plate 130 and / or the indicator 140 slide.

[0129] The outer cover 116 covers the side of the second housing 113 facing away from the first housing 112. A mounting space is defined between the outer cover 116 and the second housing 113, and the electric mechanism 170 is disposed within this mounting space. The outer cover 116 provides a protective shield for the electric mechanism 170, reducing the risk of damage to the electric mechanism 170 due to exposure.

[0130] Compared to the second portion, the first portion is closer to the middle portion of the second housing 113 on the side facing away from the first housing 112 . The second portion corresponds to the edge portion of the second housing 113 on the side facing away from the first housing 112 .

[0131] The electric mechanism 170, a key component of the switch device, is typically located in the middle of the second housing 113 on the side facing away from the first housing 112. The present application cleverly utilizes the edge of the second housing 113 facing away from the first housing 112 to provide a retaining groove 1133, which provides space for the sliding plate 130 and / or indicator 140 to slide while preventing interference with the electric mechanism 170.

[0132] like Figure 6 As shown, indicator member 140 protrudes from retaining groove 1133. The end of indicator member 140, on which the indicator mark is located, can face window 111 when the switch device is in the first and second states. Housing 116 is the exposed structural member of the switch device. Providing window 111 on housing 116 facilitates an operator's ability to discern the current state of the switch device from outside by observing the indicator mark on indicator member 140.

[0133] In this embodiment, the electric mechanism 170 is mounted on a first portion of the second housing 113 on the side facing away from the first housing 112, and the limiting groove 1133 is provided on a second portion of the second housing 113. Since the second portion is the edge of the second housing 113 on the side facing away from the first housing 112, the limiting groove 1133 only occupies a small space at the edge of the second housing 113 and does not occupy the area on the second housing 113 used for mounting the electric mechanism 170. Therefore, when the slide 130 and / or the indicator 140 slide along the limiting groove 1133, they will not interfere with the electric mechanism 170 mounted on the second housing 113.
