Description

Technical Field

[0001] This utility model relates to the field of intelligent switchgear technology, specifically to a gate mechanism for intelligent switchgear. Background Technology

[0002] The valve mechanism is an important component of switchgear, mainly used to protect the switchgear and prevent external personnel from easily opening the cabinet door due to accidental contact or impact.

[0003] According to the patent titled "A Switchgear Door Mechanism" (Patent Publication No.: CN219874591U, Patent Publication Date: 2023-10-20), it includes a contact box mounting bracket, an upper door, a lower door, and a drive assembly. The contact box mounting bracket includes two parallel sliding rods, both of which are used to pass through the upper and lower doors, allowing the upper door to reciprocate linearly up and down along the axial direction of the sliding rods. A limiting groove is formed at the top of the lower door, and a weak magnetic post is correspondingly provided at the bottom of the upper door. One end of the weak magnetic post points into the limiting groove and is magnetically connected to the limiting groove. The combined design of the weak magnetic post and the limiting groove allows the upper door to open and close smoothly with the lower door during movement, which is very convenient.

[0004] Based on the aforementioned existing technology, current intelligent switchgear door mechanisms still have the following problems: for switch panels or equipment openings with large widths, if a single swing or upward-opening door is used, the door needs to sweep a large fan-shaped space forward or upward when opening. This can seriously hinder user operation or conflict with other equipment in situations where installation space is limited. Therefore, this utility model provides an intelligent switchgear door mechanism. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides an intelligent switchgear door mechanism, which solves the following problems of existing intelligent switchgear door mechanisms: For switch panels or equipment openings with large widths, if a single swing or upward-opening door is used, the door needs to sweep a large fan-shaped space forward or upward when opening.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] Please see Figures 1-4 This utility model provides a technical solution: A smart switch device valve mechanism includes a frame 1, and a valve mechanism 2 is provided inside the frame 1 for folding and opening / closing the device opening. The valve mechanism 2 includes: The folding unit 21 is disposed inside the frame 1 and includes two half doors 213 rotatably installed inside the frame 1. One side of the half door 213 is rotatably connected to a first door panel 215 via a first connecting shaft seat 214, and one side of the first door panel 215 is rotatably connected to a second door panel 217 via a second connecting shaft seat 216. The half door 213, the first door panel 215 and the second door panel 217 are rotatably connected via the first connecting shaft seat 214 and the second connecting shaft seat 216 to achieve folding. The drive unit 22 is located above the frame 1 and is used to drive the folding unit 21.

[0018] In this embodiment, a set of second cross grooves 212 are provided at the top of the frame 1, and a set of first cross grooves 211 are provided at the bottom of the frame 1.

[0019] The sliding and rotating tracks are provided for the linkage cross block 218, upper cross block 2110 and lower cross block 219 to ensure that the door mechanism 2 moves smoothly and is accurately positioned during folding. The effect is to enhance the stability and guidance of the structure and avoid door panel offset or jamming.

[0020] In this embodiment, the top and bottom of the first door panel 215 are rotatably mounted with a linkage cross block 218, the top of the second door panel 217 is rotatably mounted with an upper cross block 2110, and the bottom of the second door panel 217 is rotatably mounted with a lower cross block 219. The two linkage cross blocks 218 rotate inside the first cross groove 211 and the second cross groove 212 respectively, the upper cross block 2110 slides inside the second cross groove 212, and the lower cross block 219 slides inside the first cross groove 211.

[0021] The linkage folding between the first door panel 215 and the second door panel 217 ensures that the components move in a coordinated manner during the opening and closing of the door.

[0022] In this embodiment, the drive unit 22 includes a miniature dual-axis motor 221 fixedly installed on the top of the frame 1. Both ends of the miniature dual-axis motor 221 are fixedly installed with lead screws 222. Both sides of the top of the frame 1 are fixedly installed with positioning shaft seats 224. The outer end of the lead screw 222 is located inside the positioning shaft seat 224 and rotates to support the positioning shaft seat 224.

[0023] The miniature dual-axis motor 221, model KH42HM2-961, is electrically connected to an external power source and operates via a human-controlled control panel. It enables the automatic folding and unfolding of the valve mechanism 2, with smooth operation and low noise.

[0024] In this embodiment, an internal thread block 223 is fixedly installed on the top of the upper cross block 2110, and the internal thread block 223 slides on the upper surface of the frame 1, and the internal thread block 223 is threadedly mounted on the surface of the lead screw 222.

[0025] Converting the rotational motion of the lead screw 222 into linear motion, which pushes the second door panel 217 to move, ensures the synchronicity and accuracy of the folding process of the door, and avoids deformation or wear caused by asynchrony.

[0026] In this embodiment, a top cover 225 is fixedly installed on the top of the frame 1 to protect the structure at the top of the frame 1. An exhaust hole is provided on the front side of the top cover 225 to dissipate heat from the inside of the first door panel 215.

[0027] The drive unit 22 is protected from external environmental influences, while the exhaust vents promote air circulation, thereby improving the equipment's protection level and heat dissipation performance, and extending the service life of the motor and door panel.

[0028] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.

[0029] During operation, the micro dual-axis motor 221 runs, driving the lead screw 222 to rotate. The lead screw 222 drives the two internal threaded blocks 223 to move synchronously in opposite directions, driving 227 to move synchronously. During the movement of 227, the first door panel 215 is driven to rotate through the second connecting shaft seat 216. The first door panel 215 rotates through the first connecting shaft seat 214, causing the second door panel 217, the first door panel 215, and the half door 213 to fold together.
