Description
Technical Field
[0001] This utility model relates to the field of low-voltage electrical technology, and in particular to a control mechanism and power equipment. Background Technology
[0002] With the continuous development of modern buildings and infrastructure, traditional distribution cabinets are widely used on branch lines and main lines. Circuit breakers, as one of the important components of distribution cabinets, are generally installed vertically or horizontally in the base plate or drawer cabinet, with the operating handle facing the cabinet door in the vertically-horizontal installation. To facilitate remote operation of the circuit breaker, it is usually equipped with an operating mechanism, which uses an external handle structure to act on an extension rod to drive the circuit breaker inside the cabinet.
[0003] In related technologies, the base plates of circuit breakers and fixed circuit breakers are installed linearly and perpendicularly to the cabinet doors as they are installed step by step along the distribution cabinet. However, with the rapid development of the communications industry and new energy storage systems, in order to meet the requirements of the new era, distribution cabinets have been replaced by distribution conversion boxes. The electrical components inside the distribution conversion box are no longer limited to vertical installation, and the new boxes no longer stand on the ground in the form of distribution cabinets. For example, the distribution conversion box is integrated into the energy storage system in the form of battery clusters, that is, the distribution conversion box is one of the integrated modules in the energy storage system. Due to integration, the form of electrical components inside the distribution conversion box needs to become more diversified. The circuit breakers inside the distribution conversion box are no longer limited to vertical and horizontal installation. Because the orientation of the extension rod in the traditional control mechanism is fixed, the traditional control mechanism is no longer applicable when the circuit breaker is installed in other orientations.

[0055] Reference Figure 1 and Figure 2 As shown, this embodiment provides a control mechanism for the opening and closing of circuit breaker 100.
[0056] Specifically, the circuit breaker 100 includes an operating handle 110, which can be used to open or close the circuit breaker 100 by rotating the operating handle 110.
[0057] Specifically, the control mechanism includes a support base 200, a slider 310, an active component 400, and a driven component 500. The slider 310 can be connected to the operating handle 110, and the sliding of the slider 310 can drive the operating handle 110 to open or close the circuit breaker 100.
[0058] Specifically, the slider 310 is slidably mounted on the support base 200; the active component 400 includes an active bevel gear 410, an extension rod 420, and a drive member 430. The active bevel gear 410 is rotatably mounted on the support base 200. The first end of the extension rod 420 is fixedly connected to the active bevel gear 410, and the second end of the extension rod 420 is connected to the drive member 430. The drive member 430 drives the extension rod 420 to rotate the active bevel gear 410. The driven component 500 includes a driven bevel gear 510 and a driven member 520. The driven bevel gear 510 is rotatably mounted on the support base 200 and meshes with the active bevel gear 410. The driven bevel gear 510 and the driven member 520 are fixedly connected, and the driven member 520 is connected to the slider 310. The rotation of the driven bevel gear 510 can drive the slider 310 to slide. The sliding direction of the slider 310, the rotation axis direction of the driven bevel gear 510, and the rotation axis direction of the operating handle 110 are perpendicular to each other. The sliding direction of slider 310 can be... Figure 1 In the x-direction, the rotation axis direction of the operating handle 110 can be... Figure 1 In the y-direction, the rotation axis direction of the driven bevel gear 510 can be... Figure 1 The z-direction in the middle.
[0059] For example, the support base 200 may be provided on the circuit breaker 100, on the cabinet (not shown) on which the circuit breaker 100 is installed, or on other components. This embodiment does not limit the scope of the support base 200.
[0060] For example, the drive unit 430 includes, but is not limited to, a handle structure, a motor, or a servo motor.
[0061] In this embodiment, after the control mechanism is connected to the circuit breaker 100, the extension rod 420 is driven by the drive member 430 to rotate the driving bevel gear 410. Under the meshing transmission of the driving bevel gear 410 and the driven bevel gear 510, the driven bevel gear 510 rotates and drives the slider 310 to slide. Since the sliding direction of the slider 310 is perpendicular to the rotation axis of the operating handle 110, the slider 310 drives the operating handle 110 to open or close the circuit breaker 100. The transmission is stable and reliable, and convenient to operate. Furthermore, due to the meshing transmission of the driving bevel gear 410 and the driven bevel gear 510, the extension rod 420 can be arranged in any direction perpendicular to the rotation axis of the driven bevel gear 510. That is, the orientation of the extension rod 420 is adjustable, so that the control mechanism is applicable to circuit breakers 100 with various installation orientations, and the control mechanism can conveniently operate the opening and closing of the circuit breaker 100.
[0062] In some embodiments, the cabinet includes a top plate and a bottom plate arranged vertically opposite each other, two side plates arranged horizontally opposite each other, and a rear plate located at the rear of the cabinet along a second horizontal direction. A cabinet door is provided at the front of the cabinet along the second horizontal direction. The vertical direction, the first horizontal direction, and the second horizontal direction are perpendicular to each other. Exemplarily, the operating handle 110 of the circuit breaker 100 faces one side plate of the cabinet, and an extension rod 420 extends vertically to the bottom plate or horizontally to the cabinet door and connects to the drive member 430 to guide the drive member 430 to a convenient operating position. Exemplarily, the operating handle 110 of the circuit breaker 100 faces the rear plate, and the extension rod 420 can extend vertically to the bottom plate of the cabinet or horizontally to the side plate and connect to the drive member 430 to guide the drive member 430 to a convenient operating position. Of course, the extension rod 420 can also extend in other directions; this embodiment is not limited to these directions.
[0063] In some embodiments, the extension rod 420 may extend through the side wall of the cabinet and connect to the drive member 430. Preferably, the extension rod 420 may extend through the lower side wall of the cabinet. Of course, the extension rod 420 may also extend through the upper side wall, left side wall, or right side wall of the cabinet; this embodiment is not limited thereto.
[0064] In one feasible implementation, such as Figures 1 to 4 As shown, one of the slider 310 and the driven member 520 has a through hole, and the other has a fixed shaft. The fixed shaft slides through the through hole for easy assembly and disassembly. In this embodiment, the through hole 521 is located on the driven member 520, and the fixed shaft 311 is located on the slider 310. When the driven member 520 rotates with the bevel gear, the wall of the through hole 521 will press against the fixed shaft 311, thereby driving the slider 310 to slide, resulting in stable and reliable transmission. It can be understood that, as Figure 1 and Figure 3 As shown, the driven bevel gear 510 rotates clockwise and counterclockwise during meshing with the driving bevel gear 410, thereby causing the fixed shaft 311 to displace in a direction parallel to the extension rod 420, which in turn causes the slider 310 to slide. The slider 310 moves in the same direction as the operating handle 110. The driven bevel gear 510 rotates around its own gear center.
[0065] For example, the perforation 521 includes, but is not limited to, an elongated hole, a round hole, or an elliptical hole. It is understood that when the perforation 521 is a round hole, its diameter is larger than the diameter of the fixed shaft 311 to prevent the transmission from jamming.
[0066] For example, the driven bevel gear 510 and the driven member 520 can be integrally formed to ensure stable and reliable transmission. Of course, the driven bevel gear 510 and the driven member 520 can also be designed separately, and this embodiment does not limit this.
[0067] For example, in order to ensure the compactness of the control mechanism and prevent positional interference between the follower 520 and the handle, the follower 520 can be made into a rod shape, and a chamfered surface 522 can be provided on the follower 520 to allow the handle to pass.
[0068] In another feasible implementation, the driven member 520 can be connected to the slider 310 via a connecting rod (not shown). The first end of the connecting rod is hinged to the driven member 520, and the other end is hinged to the slider 310. In this embodiment, when the driven member 520 rotates with the bevel gear, it can drive the slider 310 to slide via the connecting rod, resulting in stable and reliable transmission.
[0069] Of course, the follower 520 can also be connected to the slider 310 in other ways, and this embodiment does not limit it.
[0070] In some embodiments, such as Figure 4 As shown, the driven bevel gear 510 has a control groove 511 at its first end. The control mechanism also includes a screwing component (not shown), which is detachably inserted into the control groove 511 and can drive the driven bevel gear 510 to rotate. In this embodiment, if it is inconvenient to drive the driving bevel gear 410 to rotate via the drive component 430 to control the opening and closing of the circuit breaker 100, the driven bevel gear 510 can be rotated via the screwing component to control the opening and closing of the circuit breaker 100, which has good applicability.
[0071] Exemplarily, the screw mechanism includes a handle and a connecting rod detachably connected to the handle, the connecting rod being detachably inserted through the control slot 511. In some embodiments, the handle of the screw mechanism and the drive member 430 can be the same handle, and the connecting rod and the extension rod 420 can be the same rod. The handle can be selectively connected to the driving bevel gear 410 and the driven bevel gear 510 via the extension rod 420, making it more convenient to operate the circuit breaker 100. It is understood that the driving bevel gear 410 is provided with a mounting slot (not shown), and the extension rod 420 can be selectively inserted into the mounting slot and the control slot 511, wherein the mounting slot and the control slot 511 have the same shape. When the connecting rod and the extension rod 420 of the screw mechanism are different rods, the shapes of the mounting slot and the control slot 511 may be different.
[0072] For example, the control slot 511 includes, but is not limited to, a square slot or an elliptical slot. In some embodiments, both the mounting slot and the control slot 511 have two adjacent slot side surfaces, and a positioning chamfer surface 5111 is provided between the two slot side surfaces. The insertion end of the extension rod 420 into the mounting slot and the control slot 511 has the same shape as the mounting slot and the control slot 511, that is, the insertion end of the extension rod 420 is provided with a chamfer surface corresponding to the positioning chamfer surface 5111, so as to limit the angle at which the screw is inserted into the mounting slot and the control slot 511. The opening and closing status of the circuit breaker 100 can be determined by the direction of the handle.
[0073] In this embodiment, reference is made to Figure 3 and Figure 5 As shown, the support base 200 includes a support plate portion 210 with a positioning hole 211. The second end of the driven bevel gear 510 has a stepped shaft portion 512, the small end of which is rotatably inserted into the positioning hole 211. The driven assembly 500 also includes a limiting plate 530 and a connecting member 540. The support plate portion 210 is sandwiched between the limiting plate 530 and the large end of the stepped shaft portion 512, and the connecting member 540 passes through the limiting plate 530 and connects to the small end of the stepped shaft portion 512, facilitating assembly and effectively ensuring the stability of the driven bevel gear 510's rotation. Of course, the driven bevel gear 510 can also be rotatably connected to the support base 200 via bearings or other means; this embodiment does not limit this.
[0074] For example, the small end of the stepped shaft portion 512 and the positioning hole 211 can be a shaft-hole clearance fit.
[0075] For example, the limiting plate 530 can abut against the small end of the stepped shaft portion 512 to ensure the dimensional accuracy of the gap formed between the limiting plate 530 and the large end of the stepped shaft portion 512 that accommodates the support plate portion 210, thereby ensuring stable and reliable rotation of the driven bevel gear 510. The gap formed between the limiting plate 530 and the large end of the stepped shaft portion 512 can be slightly larger than the thickness of the support plate portion 210 to ensure stable rotation of the driven bevel gear 510.
[0076] For example, connector 540 may be a bolt.
[0077] For example, at least one connector 540 is provided. Preferably, at least three connectors 540 are provided at circumferential intervals along the stepped shaft portion 512, such as four, five or six, to ensure the stability of the connection of the driven assembly 500.
[0078] In one feasible implementation, the support base 200 can be formed by die stamping, specifically, as shown in the example below. Figures 1 to 3 As shown, positioning plate portions 220 are bent and extended on both opposite sides of the support plate portion 210. A groove is provided on the side of the positioning plate portion 220 away from the support plate portion 210, and a connecting plate portion 230 is formed by bending and extending from the groove. The inner side of the positioning plate portion 220 and the side away from the support plate portion 210 can abut against the outer casing 120 of the circuit breaker 100 to position the support base 200 and ensure the structural stability of the support base 200. The connecting plate portion 230 can be fixed to the outer casing 120 of the circuit breaker 100 with bolts for easy assembly. Furthermore, the projection of the support base 200 can be completely located on the outer casing 120 of the circuit breaker 100 to ensure structural compactness.
[0079] In this embodiment, as Figure 3 , Figure 6 and Figure 7 As shown, the support plate portion 210 is provided with a guide hole 212. The control mechanism also includes a guide member 320, which includes a guide post 321 and a boss 322 at the first end of the guide post 321. The second end of the guide post 321 passes through the guide hole 212 and is connected to the slider 310. The support plate portion 210 is sandwiched between the boss 322 and the slider 310. The guide hole 212 is an elongated hole. In this embodiment, the slider 310 can slide stably relative to the support base 200 by the limiting between the boss 322 and the support plate portion 210, and by the sliding guidance of the guide post 321 by the guide hole 212.
[0080] For example, the slider 310 is provided with a drive hole 312, and the operating handle 110 passes through the drive hole 312. The slider 310 slides and pushes the operating handle 110 against the wall of the drive hole 312 to open and close the circuit breaker 100. The slider 310 can be a plate-shaped structure, formed by die stamping. Along the sliding direction of the slider 310, the two opposite side walls of the drive hole 312 are bent and extended with abutment plate portions 3121. The abutment plate portions 3121 and the operating handle 110 have a large contact area, effectively preventing jamming and wear between the slider 310 and the operating handle 110.
[0081] For example, the support plate may be provided with two guide holes 212 in parallel, and each guide hole 212 is provided with at least two guide members 320 to ensure a stable and reliable sliding connection between the slider 310 and the support base 200. The drive hole 312 may be located between the two guide holes 212.
[0082] In one feasible implementation, such as Figure 7 As shown, the control mechanism also includes a limit stop 330. Specifically, the slider 310 is provided with a first through hole (not shown), and the second end of the guide post 321 passes through the guide hole 212 and the first through hole and is connected to the limit stop 330 for easy assembly.
[0083] For example, the limiting stop 330 can be set as an elastic retaining ring, which is connected to the second end of the guide post 321 by snap-fit. Of course, the limiting stop 330 can also be a threaded sleeve or other structural components, which is not limited in this embodiment.
[0084] In one feasible implementation, such as Figure 7As shown, the control mechanism also includes flat washers 340. Specifically, two flat washers 340 are fitted on the guide post 321. One of the two flat washers 340 is located between the limiting stop 330 and the slider 310 to balance the force on the limiting stop 330 and enhance connection stability. The other of the two flat washers 340 is located between the boss 322 and the support plate portion 210, that is, the other of the two flat washers 340 is sandwiched between the boss 322 and the support plate portion 210, and the other of the two flat washers 340 has a larger contact area with the support plate portion 210, enhancing connection stability. It can be understood that the outer diameter of the flat washer 340 is larger than the outer diameter of the boss 322. In this embodiment, the gap between the two flat washers 340 can be slightly larger than the sum of the thickness of the support plate portion 210 and the thickness of the slider 310 to ensure that the slider 310 can slide stably.
[0085] In this embodiment, reference is made to Figure 2 , Figures 8 to 10 As shown, the control mechanism also includes a bracket 600, on which a driving bevel gear 410 is rotatably mounted; wherein, the support base 200 has multiple mounting portions surrounding the driven bevel gear 510, and the bracket 600 can be mounted on one of the mounting portions. In this embodiment, depending on the installation orientation of the circuit breaker 100 in the cabinet, the bracket 600 can be mounted on one of the mounting portions so that the orientation of the extension rod 420 does not interfere with other components in the cabinet, and facilitates the operation of the drive component 430 and assembly.
[0086] For example, the bracket 600 and the mounting part can be fixed together by bolts. For example, the mounting part is provided with a plurality of second through holes 213 for bolts to pass through.
[0087] Specifically, the driving bevel gear 410 has a rotating shaft 411, and the bracket 600 includes a base plate 610 and two ear plates 620 connected to the base plate 610. The base plate 610 is connected to the mounting part, and the two ear plates 620 are spaced apart along the axial direction of the rotating shaft 411. Each ear plate 620 has a limiting hole 621, through which the rotating shaft 411 passes. In this embodiment, the bracket 600 is composed of a base plate 610 and two ear plates 620, which facilitates molding. Furthermore, the rotating shaft 411 passing through the limiting holes 621 on the two ear plates 620 ensures stable and reliable rotation of the driving bevel gear 410.
[0088] For example, the bracket 600 can be formed by die stamping.
[0089] In one feasible embodiment, the driving bevel gear 410 has a rotating shaft 411, a first limiting part 4111 is provided on the outer periphery of the rotating shaft 411, and a second limiting part 622 is provided on the bracket 600. The first limiting part 4111 abuts against the second limiting part 622 to limit the rotation angle of the rotating shaft 411, so that the rotation angle of the driving bevel gear 410 is just enough to drive the slider 310 to drive the operating handle 110 to open or close the circuit breaker 100. This is stable and reliable, and effectively prevents damage caused by excessive interaction forces between the driving component 400 and the driven component 500, between the driven component 500 and the slider 310, and between the slider 310 and the operating handle 110.
[0090] For example, the angle of rotation of the drive bevel gear 410 is between 60° and 150°, such as 75°, 90° or 105°.
[0091] For example, a mounting groove is provided on the end of the rotating shaft 411. To ensure a stable connection between the extension rod 420 and the rotating shaft 411, a set screw (not shown) can be passed through the periphery of the rotating shaft 411. The set screw is threaded to the rotating shaft 411 and abuts against the periphery of the extension rod 420.
[0092] For example, the first limiting part 4111 is a fan-shaped ring on the periphery of the rotating shaft 411, and the second limiting part 622 includes two protrusions 6221, with the fan-shaped ring located between the two protrusions 6221. When the fan-shaped ring abuts against one of the two protrusions 6221, the circuit breaker 100 is in the closed state; when the fan-shaped ring abuts against the other of the two protrusions 6221, the circuit breaker 100 is in the open state, to prevent the slider 310 from excessively pressing the operating handle 110 of the circuit breaker 100.
[0093] In this embodiment, to facilitate the assembly between the driving bevel gear 410 and the bracket 600, two protrusions 6221 are provided on the one of the two ear plates 620 away from the driven bevel gear 510, and a fan ring groove 6222 is provided on the one of the two ear plates 620 near the driven bevel gear 510, so as to facilitate the fan ring part passing through the fan ring groove 6222 and moving between the two ear plates 620. For example, as shown... Figure 9 As shown, the protrusion 6221 can be formed by bending and extending the edge of the ear plate 620, as... Figure 10 As shown, the ear plate 620 can also be formed by stamping with a mold. Of course, the protrusion 6221 can also be provided on the ear plate 620 in other ways, which is not limited in this embodiment.
[0094] In one feasible implementation, at least one of the driving bevel gear 410 and the driven bevel gear 510 is configured as an incomplete gear to limit the angle at which the driving bevel gear 410 drives the driven bevel gear 510 to rotate. This ensures that the angle of rotation of the driven bevel gear 510 is just sufficient for the slider 310 to drive the operating handle 110 to open or close the circuit breaker 100, ensuring stability and reliability. Furthermore, the first limiting part 4111 and the second limiting part 622 cooperate to prevent the driving bevel gear 410 and the driven bevel gear 510 from disengaging, thus ensuring stable and reliable transmission between them.
[0095] This embodiment also provides a power equipment, which includes a cabinet, a circuit breaker 100, and the aforementioned control mechanism. The circuit breaker 100 is installed inside the cabinet, and the control mechanism is located on the circuit breaker 100. The power equipment includes, but is not limited to, a distribution cabinet or a power distribution conversion box used in an energy storage system.
[0096] In this embodiment, the orientation of the control mechanism extension rod 420 can be adjusted according to the installation orientation of the circuit breaker 100 to prevent the extension rod 420 from interfering with other components inside the cabinet, and to facilitate the operation of the drive component 430, thereby improving applicability.
[0097] In one feasible implementation, the drive unit 430 is located outside the cabinet, that is, the drive unit 430 can control the circuit breaker 100 to open and close from outside the cabinet via the control mechanism.
[0098] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make various obvious changes, readjustments, and substitutions without departing from the protection scope of this utility model. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
