Description

Technical Field

[0001] This invention relates to the field of mechanical structure automation technology, and more particularly to a control structure and control method for an automated airtight door for a box. Background Technology

[0002] Automatic sealing door devices are a common type of device used in many pieces of equipment to achieve the opening, closing, and sealing of equipment or enclosures. In existing technical solutions, such devices are generally operated manually.

[0003] However, in practical applications, there are some special operating scenarios that often require manual isolation. In these environments, due to safety regulations or space constraints, operators cannot directly access the equipment, or it is difficult to meet the conditions required for manual operation. Continuing to use traditional manual operation methods will not meet the needs of these specific environments. In addition, existing ordinary automatic door structures often lack an effective clamping mechanism that works in conjunction with the track structure, making it difficult to achieve a highly reliable clamping and sealing effect while automatically closing.

[0004] Therefore, there is an urgent need for a control scheme that can replace manual operation, using motors and sensors in conjunction with specific mechanical structures to solve the technical problem of automatically closing and sealing the door structure in environments requiring manual isolation. Summary of the Invention

[0005] To achieve the above objectives, the present invention provides a transmission structure, comprising: an electrical structure, a transmission mechanism, and a mechanical structure; The electrical structure includes a motor and a position sensor, the transmission mechanism includes a lead screw structure, and the mechanical structure includes a clamping mechanism, a door structure, and a track structure. The track structure is provided with a track direction to guide the movement of the door structure; the motor controls the movement of the lead screw structure, the lead screw structure drives the clamping mechanism to move, and the clamping mechanism drives the door structure to move along the track structure; the position sensor is used to send signals to control the working and stopping states of the electrical structure.

[0006] Furthermore, the clamping mechanism is connected to the door structure, and the door structure moves under the constraint of the track structure; when the door structure moves to the designated closed position, the track structure guides the door structure into the designated track, and cooperates with the clamping mechanism to realize the closing and clamping action.

[0007] Furthermore, the position sensor is pre-set to control the start and end positions of the lead screw structure and the clamping mechanism; when the clamping mechanism reaches the designated position, the position sensor transmits a signal to the motor to control the motor and the lead screw structure to stop transmission.

[0008] This invention also provides a control method for an automated airtight door for a housing, applied to the control structure of the aforementioned automated airtight door for a housing, comprising the following steps: S1. The electrical structure drives the mechanical structure, and the working and stopping states of the electrical structure are controlled by the signal from the position sensor, thereby controlling the state of the mechanical structure; S2. Control the motor to drive the lead screw structure to move, thereby driving the clamping mechanism to pull up and clamp the door structure; S3. The movement direction of the door structure is controlled by the structure of the track structure, and the clamping force of the clamping mechanism is controlled. S4. The starting and ending positions of the lead screw structure and the clamping mechanism are controlled by the signal from the position sensor.

[0009] Furthermore, the step of controlling the clamping force of the clamping mechanism specifically includes: The track structure is controlled by coordinating its track direction with the clamping mechanism. When the clamping mechanism reaches the designated position, the position sensor transmits a signal to the motor, controlling the motor and the lead screw structure to stop transmission, and the clamping mechanism stops lifting.

[0010] Furthermore, it also includes a closing and pressing sealing step: when the pressing mechanism drives the door structure to the designated closing position, it controls the door structure to enter the designated track to perform the closing and pressing sealing action.

[0011] By adopting the above technical solution, the present invention has the following advantages compared with the prior art: 1. This invention provides a control structure and method for an automated airtight door for enclosures. By employing an automated control method where an electrical structure drives a mechanical structure, the combination of a motor and a position sensor replaces traditional manual operation. This design effectively solves the technical problem of difficulty in directly operating the automatic airtight door device due to space limitations or safety regulations in environments requiring manual isolation, thus achieving fully automated operation of the sealing process.

[0012] 2. This invention provides a control structure and method for an automated airtight door for a housing, utilizing the track direction of a track structure to control the clamping force of the clamping mechanism. When the door structure reaches the designated closed position, it enters the designated track and is pulled up and clamped by the clamping mechanism. This structural design ensures that the door structure can close tightly and seal the interface of the housing requiring airtightness, significantly improving the airtightness.

[0013] 3. The present invention provides a control structure and method for an automated airtight door for a box-type structure. The transmission mechanism adopts a lead screw structure, combined with a position sensor for precise monitoring of the start and end positions. The position sensor can transmit signals to the motor in real time to control the action state of the lead screw structure and the clamping mechanism. This control logic not only ensures the accuracy of the door structure's movement direction but also achieves precise control of the lifting action of the clamping device, thereby ensuring the stability and reliability of the entire automatic clamping and closing process.

[0018] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. The following description of at least one exemplary embodiment is merely illustrative and is in no way intended to limit the present invention or its application or use. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0019] It should be noted that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the scope of exemplary embodiments according to the invention. As used herein, the singular form is intended to include the plural form as well, unless the context clearly indicates otherwise. Furthermore, it should be understood that when the terms "comprising" and / or "including" are used in this specification, they indicate the presence of features, steps, operations, devices, components, and / or combinations thereof.

[0020] Unless otherwise specifically stated, the relative arrangement, numerical expressions, and values ​​of the components and steps set forth in these embodiments do not limit the scope of the invention. It should also be understood that, for ease of description, the dimensions of the various parts shown in the drawings are not drawn to actual scale. Techniques, methods, and devices known to those skilled in the art may not be discussed in detail, but where appropriate, such techniques, methods, and devices should be considered part of the specification. In all examples listed and discussed herein, any specific values ​​should be interpreted as merely exemplary and not as limitations. Therefore, other examples of exemplary embodiments may have different values. It should be noted that similar reference numerals and letters in the following figures denote similar items; therefore, once an item is defined in one figure, it need not be further discussed in subsequent figures.

[0021] In the description of this invention, it should be understood that the orientation or positional relationship indicated by directional terms such as "front, back, up, down, left, right", "horizontal, vertical, horizontal" and "top, bottom" is generally based on the orientation or positional relationship shown in the accompanying drawings, and is only for the convenience of describing this invention and simplifying the description. Unless otherwise stated, these directional terms do not indicate or imply that the device or element referred to must have a specific orientation or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation on the scope of protection of this invention. The directional terms "inner" and "outer" refer to the inner and outer contours relative to the outline of each component itself.

[0022] For ease of description, spatial relative terms such as "above," "on top of," "on the upper surface of," "above," etc., are used herein to describe the spatial positional relationship of a device or feature as shown in the figures to other devices or features. It should be understood that spatial relative terms are intended to encompass different orientations in use or operation beyond the orientation of the device as described in the figures. For example, if the device in the figures were inverted, a device described as "above" or "on top of" other devices or structures would subsequently be positioned as "below" or "under" other devices or structures. Thus, the exemplary term "above" can include both "above" and "below." The device may also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatial relative descriptions used herein will be interpreted accordingly.

[0023] Furthermore, it should be noted that the use of terms such as "first" and "second" to define components is merely for the purpose of distinguishing the corresponding components. Unless otherwise stated, the above terms have no special meaning and therefore should not be construed as limiting the scope of protection of this invention.

[0024] Example 1 like Figures 1 to 4 As shown, the present invention provides a control structure for an automated airtight door for a box, comprising: an electrical structure, a transmission mechanism, and a mechanical structure.

[0025] Specifically, the electrical structure includes a motor 1 and a position sensor 2. Motor 1 serves as the power source, outputting torque; position sensor 2 detects the position of moving parts and sends signals to control the operation and stop states of the electrical structure. The transmission mechanism mainly includes a lead screw structure 3. The lead screw structure 3 connects motor 1 to the mechanical structure, converting the rotational motion of motor 1 into linear motion. The mechanical structure includes a clamping mechanism 4, a door structure 5, and a track structure 6.

[0026] Regarding the connection and coordination of the various components: Motor 1 controls the movement of lead screw structure 3, lead screw structure 3 drives the clamping mechanism 4, and clamping mechanism 4 is connected to door structure 5, thereby driving door structure 5 to move along track structure 6. Track structure 6 has a specific track direction to guide the movement direction of door structure 5. Position sensor 2 is configured to send signals to the electrical structure, thereby precisely controlling the start and stop of the entire structure. Through the electrical structure driving the mechanical structure, and using the signals from position sensor 2 to control the working state, automated control of the airtight door is achieved, solving the problem of manual operation being difficult to implement in isolated environments.

[0027] To achieve a good sealing effect, in this embodiment, the movement of the door structure 5 is constrained by the track structure 6 throughout its entire movement. The track structure 6 is not a simple linear guide; it has a specific design at the "designated closed position." When the motor 1 moves the door structure 5 to the designated closed position via the lead screw structure 3 and the clamping mechanism 4, the door structure 5 is guided into the designated track. At this time, the track structure 6's inherent design restricts the direction of movement of the door structure 5, and in conjunction with the continuous pulling or pushing force of the clamping mechanism 4, the door structure 5 generates a clamping action at the closed position. This achieves a tight mechanical closure and seals the interface of the enclosure requiring airtightness. By utilizing the specific guidance of the track structure 6 and cooperating with the clamping mechanism 4, it is ensured that the door structure 5 not only reaches the correct position when closed but also generates sufficient clamping force, achieving a rigorous automatic sealing process and improving the sealing reliability of the equipment.

[0028] In terms of control logic, position sensor 2 is pre-set to control the start and end positions of lead screw structure 3 and clamping mechanism 4. When clamping mechanism 4 follows lead screw structure 3 to the designated position, position sensor 2 transmits a signal to motor 1, controlling motor 1 and lead screw structure 3 to stop transmission, thereby ensuring that door structure 5 stays in the accurate working position. By pre-setting position sensor 2, precise control of the start and end positions of lead screw structure 3 and clamping mechanism 4 is achieved, preventing the mechanical structure from over- or under-positioning, and ensuring the accuracy and safety of the automation process.

[0029] Example 2 like Figure 5 As shown, based on the structure in Embodiment 1 above, this embodiment further provides a control method for an automated airtight door control structure for a housing. This method uses an electrical structure to drive a mechanical structure, achieving a tight closure and sealing of the interface of the housing requiring airtightness, thus realizing an automatic opening and closing airtight process. The method specifically includes the following steps: Step S1: Use the electrical structure to drive the mechanical structure. Specifically, control the working and stopping states of the electrical structure through the signal of the position sensor 2, thereby controlling the state of the mechanical structure.

[0030] Step S2: Control motor 1 to drive lead screw structure 3 to move. The movement of lead screw structure 3 drives the clamping mechanism 4 connected to it to pull up and clamp the door structure 5. In this process, motor 1 provides power, and lead screw structure 3 is responsible for the transmission and conversion of power.

[0031] Step S3: The movement direction of the door structure 5 is controlled by the structure of the track structure 6, and the clamping force of the clamping mechanism 4 is also controlled. Specifically, the clamping force of the clamping mechanism 4 is controlled by the track direction of the track structure 6 in conjunction with the clamping mechanism 4. The track structure 6 not only serves as a guide, but its specific track structure 6 can also assist the clamping mechanism 4 in applying pressure at specific positions.

[0032] Step S4: Control the start and stop positions of the lead screw structure 3 and the clamping mechanism 4 through the signal from the position sensor 2. The specific control process is as follows: when the clamping mechanism 4 reaches the designated position, the position sensor 2 transmits a signal to the motor 1, controlling the motor 1 and the lead screw structure 3 to stop transmission, and the clamping mechanism 4 stops lifting.

[0033] Furthermore, the control method also includes a crucial closing and tightening sealing step: when the clamping mechanism 4 drives the door structure 5 to the designated closed position, the door structure 5 is controlled to enter the designated track to perform the closing and tightening sealing action. At this time, under the combined action of the track structure 6 and the clamping mechanism 4, the door structure 5 achieves effective sealing of the box interface.

[0034] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and are not intended to limit them. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
