Description

Technical Field

[0001] This utility model relates to the field of container door opening technology, and in particular to an automatic door opening mechanism. Background Technology

[0002] Currently, mainstream energy storage stations generally use containers of 20 feet, 22 feet, and 40 feet in size, with varying widths for different lengths. Traditional container opening methods primarily rely on manual operation, which is labor-intensive, inefficient, and costly. While some systems now employ automated opening mechanisms, these are complex in design, have poor compatibility, and cannot meet the needs of automatically opening and closing containers of varying lengths and widths. Utility Model Content

[0003] The technical problem to be solved by this utility model is to overcome the shortcomings of the existing technology and provide an automatic door opening mechanism with a simple structural design that can be compatible with containers of various sizes.

[0004] The technical solution adopted by this utility model to solve its technical problem is: an automatic door opening mechanism, including a truss and an automatic door opening assembly disposed on the truss. The automatic door opening assembly includes a fixed base, a transverse drive assembly, a rotating frame, a rotating assembly, a transverse assembly, a mounting base, a longitudinal drive assembly, and a door suction assembly. The fixed base is slidably connected to the truss. The transverse drive assembly is mounted on the fixed base to drive the fixed base to slide laterally along the truss. One end of the rotating frame is connected to the fixed base through the rotating assembly. The transverse assembly is mounted on the other end of the rotating frame. The transverse assembly includes a sliding plate. The mounting base is slidably connected to the sliding plate. The longitudinal drive assembly is mounted on the sliding plate to drive the mounting base to slide longitudinally along the sliding plate. The door suction assembly is mounted on the mounting base for suctioning the box door.

[0005] Furthermore, the lateral movement assembly also includes a first driving member, a connecting plate, and a roller. The top end of the first driving member is connected to the end of the rotating frame away from the fixed seat, and the bottom end of the first driving member is slidably connected to the slide plate. The connecting plate is installed on one side of the slide plate, and the roller is installed on the driving end of the first driving member. The roller is embedded in a groove opened at the top of the connecting plate.

[0006] Furthermore, the lateral movement assembly also includes a blocking block and a centering device. The blocking block is installed at the bottom center of the first drive member, and the centering device is installed at the center of the connecting plate, with the centering device corresponding to the blocking block.

[0007] Furthermore, the door catch assembly includes a mounting plate and an electromagnet, the top of the mounting plate being connected to a mounting base, and the electromagnet being disposed on the side of the mounting plate away from the mounting base.

[0008] Furthermore, the door catch assembly also includes an elastic element disposed between the mounting base and the mounting plate. One end of the elastic element is connected to the mounting base, and the other end of the elastic element is connected to the mounting plate. The mounting base and the mounting plate are hinged together.

[0014] The beneficial effects of this utility model are:

[0015] (1) This utility model drives the fixed seat to slide laterally along the truss by the transverse drive component until the door suction component comes to the working position. Then the longitudinal drive component drives the mounting seat to slide longitudinally along the slide plate until the door suction component contacts the container door. The door suction component sucks the container door. The cooperation of the rotating component and the transverse component opens the container door to the working angle. The whole process is automated. The overall structure design is simple and can meet the opening and closing of containers of different lengths and widths.

[0016] (2) This utility model achieves floating connection by embedding rollers in the groove at the top of the connecting plate, so as to avoid jamming of the mechanism under different mounting surfaces.

Detailed Implementation

[0028] The present invention will now be further described with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the present invention, and therefore only show the components relevant to the present invention.

[0029] like Figures 1-3As shown, an automatic door opening mechanism includes a truss 100 and an automatic door opening assembly 200 disposed on the truss 100. The automatic door opening assembly 200 includes a fixed base 210, a lateral movement drive assembly 220, a rotating frame 230, a rotating assembly 240, a lateral movement assembly 250, a mounting base 260, a longitudinal movement drive assembly 270, and a door catch assembly 280. The fixed base 210 is slidably connected to the truss 100, and the lateral movement drive assembly 220 is mounted on the fixed base 210 to drive the fixed base. 210 slides laterally along truss 100. One end of rotating frame 230 is connected to fixed seat 210 via rotating assembly 240. Lateral movement assembly 250 is installed at the other end of rotating frame 230. Lateral movement assembly 250 includes slide plate 251. Mounting seat 260 is slidably connected to slide plate 251. Longitudinal movement drive assembly 270 is installed on slide plate 251 to drive mounting seat 260 to slide longitudinally along slide plate 251. Door suction assembly 280 is installed on mounting seat 260 for suctioning box door. The lateral drive assembly 220 drives the fixed seat 210 to slide laterally along the truss 100 until the door suction assembly 280 arrives at the working position. Then, the longitudinal drive assembly 270 drives the mounting seat 260 to slide longitudinally along the slide plate 251 until the door suction assembly 280 contacts the container door. The door suction assembly 280 sucks the container door, and the cooperation of the rotation assembly 240 and the lateral drive assembly 250 opens the container door to the working angle. The whole process is automated, the overall structure design is simple, and it can meet the opening and closing requirements of containers of different lengths and widths.

[0030] Specifically, the truss 100 is mounted on a ground rail (not shown in the figure); the automatic door opening assembly 200 consists of two sets, arranged opposite each other; the rotating frame 230 is L-shaped; the rotating assembly 240 uses a rotary motor; and the longitudinal movement drive assembly 270 uses a cylinder.

[0031] like Figure 2 , Figure 4 and Figure 6 As shown, the lateral movement assembly 250 also includes a first driving member 252, a connecting plate 253, and a roller 254. The top end of the first driving member 252 is connected to the end of the rotating frame 230 away from the fixed base 210, and the bottom end of the first driving member 252 is slidably connected to the slide plate 251. The connecting plate 253 is installed on one side of the slide plate 251, and the roller 254 is installed on the driving end of the first driving member 252. The roller 254 is embedded in a groove opened at the top end of the connecting plate 253. By embedding the roller 254 in the groove opened at the top end of the connecting plate 253, a floating connection is achieved to avoid jamming of the mechanism under different mounting surfaces. Specifically, the first driving member 252 is a rodless cylinder.

[0032] like Figure 6 and Figure 7As shown, the lateral movement assembly 250 also includes a blocking block 255 and a centering device 256. The blocking block 255 is installed at the bottom center of the first driving member 252, and the centering device 256 is installed at the center of the connecting plate 253, corresponding to the blocking block 255. Through the cooperative arrangement of the blocking block 255 and the centering device 256, the blocking and centering function of the driving end of the first driving member 252 is achieved.

[0033] like Figure 6 and Figure 8 As shown, the door catch assembly 280 includes a mounting plate 281 and an electromagnet 282. The top of the mounting plate 281 is connected to the mounting base 260, and the electromagnet 282 is disposed on the side of the mounting plate 281 away from the mounting base 260. Specifically, there are two electromagnets 282.

[0034] like Figure 8 As shown, the door catch assembly 280 also includes an elastic element 283, which is disposed between the mounting base 260 and the mounting plate 281. One end of the elastic element 283 is connected to the mounting base 260, and the other end is connected to the mounting plate 281. The mounting base 260 and the mounting plate 281 are hinged. The hinge between the mounting base 260 and the mounting plate 281, along with the elastic element 283, constitutes a floating structure. During the opening and closing operation, as the door catch assembly 280 moves, the mounting plate 281 rotates around the hinge point at a certain angle. At this time, the elastic element 283 deforms and generates elastic force. After completing the opening of the previous door, in order not to affect the opening of the next door, in the non-operating state, the elastic element 283 uses its elastic restoring force to pull the mounting plate 281, thereby restoring the mounting plate 281 to its initial state. Specifically, the elastic element 283 is a spring.

[0035] like Figure 8 As shown, the door catch assembly 280 also includes a first limit switch 284, which is mounted on the mounting plate 281 and used to sense the door. Specifically, there are two first limit switches 284, symmetrically arranged on the left and right sides of the mounting plate 281.

[0036] like Figures 3-5 As shown, the lateral drive assembly 220 includes a second drive member 221, a rack 222, and a gear 223. The second drive member 221 is mounted on the fixed base 210, the rack 222 is laterally arranged on the truss 100, and the gear 223 is mounted on the drive end of the second drive member 221, meshing with the rack 222. Specifically, the second drive member 221 is a motor.

[0037] like Figure 7 As shown, the front and rear ends of the mounting base 260 are respectively equipped with first buffers 300 to prevent the sliding plate 251 from rigidly colliding with the mounting base 260 at the end of the longitudinal stroke.

[0038] like Figure 6 As shown, second buffers 400 are installed at both ends of the first drive member 252 to prevent the slide plate 251 from rigidly colliding with the first drive member 252 at the end of its lateral travel. A second limit switch 500 is installed at the end of the first drive member 252 away from the rotating assembly 240 to form a limit stop and prevent the mechanism from colliding with the truss 100.

[0039] During operation, the transverse drive assembly 220 drives the fixed base 210 to slide laterally along the truss 100 until the door catch assembly 280 moves to the working position. Then, the longitudinal drive assembly 270 drives the mounting base 260 to slide longitudinally along the slide plate 251 until the door catch assembly 280 contacts the cabinet door. The electromagnet 282 in the door catch assembly 280 is energized to attract the cabinet door. The rotation assembly 240 drives the rotation frame 230 to rotate. At the same time, the transverse drive assembly 250 drives the door catch assembly 280 to move laterally, thereby opening the cabinet door to the working angle.

Their purpose is to enable those skilled in the art to understand the content of this utility model and implement it. They should not be used to limit the protection scope of this utility model. All equivalent changes or modifications made in accordance with the spirit and essence of this utility model should be covered within the protection scope of this utility model.
