Description

Technical Field

[0001] This utility model relates to the field of power equipment technology, and in particular to an electric pressure plate. Background Technology

[0002] Pressure plates are typically installed in the secondary circuits of protection devices, measurement and control devices, etc. They connect or disconnect the circuit mechanically to enable or disable the corresponding protection or automation functions.

[0003] like Figure 1 and Figure 2 As shown, the pressure plate 1 typically includes a pressure plate base 2 and a pressure plate connecting piece 3. A rotating shaft 7 is connected downwards to the center of the pressure plate connecting piece 3. The pressure plate base 2 has a shaft hole 9 in the center that mates with the rotating shaft 7, allowing the pressure plate connecting piece 3 to be axially displaced and rotatably mounted on the pressure plate base 2 via the rotating shaft 7. The pressure plate connecting piece 3 has downward-facing insertion posts 8 at both ends, and the pressure plate base 2 has insertion holes 4 at both ends that mate with the insertion posts 8. Two terminal posts 5 are connected to the bottom of the pressure plate base 2, each corresponding to one of the two insertion holes 4. (Refer to...) Figure 2 When the pressure plate 1 rotates and the two pins 8 engage with the two holes 4 respectively, the pressure plate 1 switches to the closed position, connecting the circuit and enabling the corresponding function of the circuit to operate normally. (Refer to...) Figure 1 When the pressure plate 1 rotates and separates the two pins 8 from the two sockets 4, the pressure plate 1 switches to the disconnected position, cutting off the circuit and rendering the corresponding function inactive. When the pressure plate 1 is in the disconnected position, the two pins 8 can be inserted into the locating sockets 6 on both sides of the pressure plate base 2.

[0004] Existing pressure plates typically rely on manual operation of the pressure plate connecting piece 3, which is complex, labor-intensive, and has low inspection efficiency. Furthermore, it is prone to omissions or operational errors, which can lead to malfunctions or failures to activate protection devices, causing safety accidents. In recent years, electric pressure plates have emerged; however, existing electric pressure plates are large in size, occupying significant installation space, and require modifications to the traditional pressure plate structure, making them unsuitable for direct installation on traditional pressure plates and resulting in poor compatibility.

Detailed Implementation

[0018] To further illustrate the various embodiments, the present invention provides accompanying drawings. These drawings are part of the disclosure of the present invention and are mainly used to illustrate the embodiments, and can be used in conjunction with the relevant descriptions in the specification to explain the operating principles of the embodiments. With reference to these drawings, those skilled in the art should be able to understand other possible implementations and the advantages of the present invention. Components in the drawings are not drawn to scale, and similar component symbols are generally used to represent similar components.

[0019] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments.

[0020] like Figures 1-13 As shown, this embodiment provides an electric pressure plate 10, including a main body 11; refer to Figures 6-8 The main body 11 is a shell structure with openings at the top and bottom. A partition 111 divides it into an upper chamber 112 and a lower chamber 113. The upper chamber 112 is used to install the motor 12. The lower chamber 113 is shaped to engage with the pressure plate connecting piece 3 of the pressure plate 1 when it is in the disconnected position. The partition 111 can completely isolate the upper chamber 112 and the lower chamber 113, or it can only partially isolate them, meaning the upper chamber 112 and the lower chamber 113 can be interconnected. Omitting the partition 111 is also a feasible solution. When the lower chamber 113 of the main body 11 engages with the pressure plate connecting piece 3, the partition 111 can position the main body 11 on the upper surface of the pressure plate connecting piece 3; that is, the partition 111 can function as a positioning element with a positioning function.

[0021] The main body 11 also includes two conductive post channels 114 penetrating the partition 111. These channels are used to install conductive posts 13. The conductive posts 13 are made of conductive materials, such as copper or other conductive metals. When the conductive posts 13 are installed into the main body 11, their lower ends protrude into the lower cavity 113. Figure 8As shown. Furthermore, see further reference. Figure 4 and Figure 5 When the lower chamber 113 of the main body 11 is engaged with the pressure plate connecting piece 3, the lower end of the conductive post 13 engages with the insertion hole 4 of the pressure plate base 2.

[0022] The motor 12 is installed in the upper chamber 112 of the main body 11, located between two conductive posts 13. The rotating shaft of the motor 12 is connected to the middle of a conductive rotating plate 15. The conductive rotating plate 15 contains conductive material. The motor 12 can drive the conductive rotating plate 15 to rotate, so that both ends of the conductive rotating plate 15 are engaged or disengaged from the two conductive posts 13, thereby making or breaking the circuit between the two copper conductive posts 13. The motor 12 and the conductive rotating plate 15 constitute an electric operating mechanism for making or breaking the circuit between the two conductive posts 13. This electric pressure plate 10 can be directly installed on an existing pressure plate without changing the structure of the existing pressure plate, which has better compatibility and adaptability, greatly simplifies the installation process, and improves installation efficiency.

[0023] Reference Figure 8 The lower chamber 113 includes a connecting piece mating portion 1131 that mates with the pressure plate connecting piece 3. The connecting piece mating portion 1131 is inclined relative to the main body 11, thereby adapting to the shape of the pressure plate connecting piece 3 in the disconnected position. The lower chamber 113 has a locking protrusion 1132 on the inner end face of the connecting piece mating portion 1131. The locking protrusion 1132 can lock with the pressure plate connecting piece 3, thereby forming a firm locking structure between the main body 11 and the pressure plate connecting piece 3, which enhances safety.

[0024] The upper chamber 112 of the main body 11 also has a control module mounting space 1121 for mounting the control module 20. The control module 20 is, for example, a PCBA, and is electrically connected to the motor 12. The control module 20 can be used to receive control commands to control the rotation, stop, and direction of rotation of the motor 12. For example, when the control module 20 receives a control command to control the engagement of the pressure plate, the control module 20 controls the rotating shaft of the motor 12 to rotate clockwise, and the rotation of the rotating shaft of the motor 12 simultaneously drives the conductive rotating plate 15 to rotate clockwise. When the conductive rotating plate 15 rotates to its position, the two copper conductive posts 13 are connected.

[0025] A cover plate mounting groove 115 is provided circumferentially at the upper end of the main body 11. The cover plate mounting groove 115 is used to install the cover plate 14, thereby isolating the conductive rotating plate 15 from the motor 12 below, which is beneficial to improving safety. An upper cover 19 is also installed above the main body 11. The upper cover 19 covers the outer periphery of the conductive rotating plate 15, thereby protecting the conductive rotating plate 15 and further enhancing safety. Two viewing notches 191 are also provided on the upper cover 19. The two viewing notches 191 are located diagonally on the upper cover 19. Through the two viewing notches 191, the engagement or disengagement state of the conductive rotating plate 15 and the conductive post 13 can be easily observed, as shown below. Figure 3 and Figure 9 As shown, this allows for a direct observation of whether the pressure plate is in place, providing a convenient and reliable way to obtain the status of the pressure plate.

[0026] A snap-fit ​​boss 131 is provided on the conductive post 13. The snap-fit ​​boss 131 can be firmly snapped into the snap-fit ​​hole of the cover plate 14, thereby positioning the conductive post 13 in the cavity of the main body 11.

[0027] A limiting boss 132 is also provided on the conductive post 13. The outer peripheral surface of the limiting boss 132 is used to contact the conductive rotating plate 15. The diameter of the limiting boss 132 is larger than the diameter of the conductive post 13, thereby increasing the contact area with the conductive rotating plate 15 and making the contact more stable and reliable.

[0028] A voltage-conducting cap 16 and a spring 17 are slidably fitted onto the conductive post 13. The voltage-conducting cap 16 is positioned above the limiting boss 132. The two ends of the spring 17 abut against the voltage-conducting cap 16 and the upper cover 19, respectively. The spring 17 is used to press down the voltage-conducting cap 16, and the limiting boss 132 limits the voltage-conducting cap 16. The upper end face of the limiting boss 132 is slightly lower than the upper end face of the conductive rotating piece 15. When the conductive rotating piece 15 rotates to engage with the conductive post 13, the conductive rotating piece 15 pushes the voltage-conducting cap 16 upward, thereby abutting against the conductive post 13. Under the pressure of the voltage-conducting cap 16 and the spring 17, the conductive rotating piece 15 can ensure good contact between itself and the conductive post 13.

[0029] Reference Figure 11 and Figure 13The conductive cap 16 includes a cap neck 163 and a cap head 161 connected to each other. The cap neck 163 enhances the guiding performance of the conductive cap 16 as it moves up and down the conductive post 13. The edge of the cap head 161 is provided with a cap guide portion 162. The conductive rotating piece 15 includes hook-shaped structures 151 at both ends. The edges of the hook-shaped structures 151 are provided with rotating piece guide portions 153. The cap guide portion 162 and the rotating piece guide portion 153 are chamfered or rounded. By providing the cap guide portion 162 and the rotating piece guide portion 153, the conductive rotating piece 15 can more easily rotate to engage with the conductive post 13, thereby saving system energy and improving system reliability.

[0030] Reference Figure 4 , Figure 11 and Figure 12 In this embodiment, the rotating shaft of the motor 12 is connected to the center of the conductive rotating plate 15 via an insulating ring 21. The insulating ring 21 can be made of insulating material, thereby improving the electrical isolation performance between the conductive rotating plate 15 and the motor 12, and enhancing the safety and durability of the equipment. The insulating ring 21 is fitted onto the rotating shaft of the motor 12 in a non-rotatable manner. In this embodiment, the central hole 211 of the insulating ring 21 is D-shaped, and the cross-section of the rotating shaft of the motor 12 is also D-shaped, thus achieving the non-rotatable fitting of the insulating ring 21 onto the rotating shaft of the motor 12. The conductive rotating plate 15 is fitted onto the outer periphery of the insulating ring 21 in a non-rotatable manner, and the outer periphery 212 of the insulating ring 21 is non-circular. In this embodiment, the outer periphery 212 of the insulating ring 21 is shown to be D-shaped. Of course, in other embodiments, the outer periphery 212 of the insulating ring 21 can also be rectangular, star-shaped, gear-shaped, etc. A limiting opening 152 is provided in the center of the conductive rotating plate 15. The shape of the limiting opening 152 is adapted to the outer periphery 212 of the isolation ring 21. In this embodiment, the limiting opening 152 is also D-shaped. Of course, in some embodiments, a motor with isolation function can also be used to improve electrical isolation performance.

[0031] To facilitate the acquisition of the open or closed state of the electric pressure plate 10, a position detection sensor 18 is also installed on the inner side of the upper cover 19 in this embodiment. The position detection sensor 18 is used to acquire the position and / or deflection angle of the conductive rotating plate 15 and / or the insulating ring 21. For example, the position detection sensor 18 can be a Hall sensor 18, and a magnetic marker 211 is provided on the conductive rotating plate 15 or the insulating ring 21, such as... Figure 12As shown, in this embodiment, the magnetic marker 211 is disposed on the isolation ring 21. When the conductive rotating plate 15 rotates to engage or disengage with the conductive post 13, the magnetic marker 211 causes the Hall sensor 18 to be in different states, such as triggered and non-triggered states, thereby enabling real-time acquisition of the state of the electric pressure plate 10, facilitating remote control, and also improving safety by acquiring the state of the electric pressure plate 10. Of course, in some other embodiments, the position detection sensor 18 can also be an angle sensor, which determines the state of the electric pressure plate 10 by detecting the rotation angle of the conductive rotating plate 15; or, the position detection sensor 18 can also be other types of proximity switches, such as photoelectric proximity switches. The position detection sensor 18 can be electrically connected to the control module 20. In use, when the position detection sensor 18 detects that the conductive rotating plate 15 has rotated to the correct position, the control module 20 controls the motor 12 to stop. In some embodiments, the position detection sensor 18 can be integrated with the control module 20.

[0032] The operation of the electric pressure plate 10 is as follows: When the control module 20 receives a control command to activate the pressure plate, the control module 20 controls the rotating shaft of the motor 12 to rotate clockwise. Simultaneously, the rotating shaft of the motor 12 drives the conductive rotating plate 15 to rotate clockwise. When the conductive rotating plate 15 reaches its designated position, it connects the two conductive posts 13. The position detection sensor 18 detects that the conductive rotating plate 15 has reached its designated position, and the control module 20 stops the motor 12. Under the pressure of the conductive cap 16 and the spring 17, the conductive rotating plate 15 maintains good contact with the conductive posts 13.

[0033] When the control module 20 receives a control command to retract the pressure plate, it controls the motor 12 to rotate counterclockwise. Simultaneously, the rotating motor 12 drives the conductive rotating plate 15 to rotate counterclockwise. When the conductive rotating plate 15 reaches its designated position, the two conductive posts 13 disengage from the conductive rotating plate 15. The position detection sensor 18 detects that the conductive rotating plate 15 has retracted to its designated position, and the control module 20 stops the motor 12. This method ensures reliable disconnection between the conductive rotating plate 15 and the conductive posts 13.
