Description

Technical Field

[0001] This utility model relates to the field of trackless drive door technology, specifically a trackless drive driver's correction connector. Background Technology

[0002] With the development of automation technology, trackless drive doors, as a new type of door control system, have been increasingly widely used in modern buildings and industrial environments. Their main feature is the elimination of traditional ground rails, making the door more flexible in opening and closing, avoiding the hassle of grooving the ground or installing tracks, and reducing operational obstructions caused by ground obstacles, thus improving overall aesthetics and convenience.

[0003] Currently, trackless drive doors on the market typically operate based on the principle that a trackless drive device directly drives the door to open and close. The core of this design concept is to integrate the trackless drive device (such as a base with a drive motor and wheels) on one side or below the door, and use the movement of the drive device to directly drive the entire door to move or rotate.

[0004] However, in practical applications, trackless drive door systems still face some challenges due to the following reasons: Installation accuracy limitations: Even with trackless drive systems, there are still certain errors in the installation position and the door itself. These errors may stem from insufficient precision in on-site construction, uneven ground, or manufacturing tolerances of the door itself.

[0005] Deviations during operation: During frequent opening and closing, the door is affected by factors such as wind, collisions, structural deformation, and wear and tear on the drive device itself, causing deviations in the door's running trajectory, deviating from the ideal straight line or preset trajectory.

[0006] Wear and tear on the drive unit: When the door body deviates, the trackless drive unit may be subjected to uneven force, causing the wheels, drive motor or transmission system to bear excessive lateral force or torque, thereby accelerating wear, shortening service life, or even causing failure.

[0007] Impact on smooth operation: If the door deviates from the track during operation, it will increase the running resistance, produce abnormal noise, affect the smoothness of the door, and reduce the user experience.

[0008] Difficulty in effectively correcting deviations: In traditional trackless drive door systems, once a deviation occurs, it is often necessary to stop the machine for inspection and manually adjust the installation position of the drive device or recalibrate the door body. This process is time-consuming and labor-intensive, and the calibration accuracy is difficult to guarantee.

[0009] Therefore, there is an urgent need for a technology that can effectively compensate for and correct deviations in the operation of the door, based on the direct opening and closing of the door by the trackless drive device, so as to improve its operating accuracy, smoothness and reliability, and extend its service life. Utility Model Content

[0010] Purpose of the utility model: To provide a trackless drive with a correction connector that directly drives the door to open and close, effectively compensating for and correcting deviations during the door's operation, thereby improving its operating accuracy, smoothness, and reliability, and extending its service life.

[0011] To achieve the above objectives, this utility model provides the following technical solution: A trackless drive's alignment connector includes: The female component has a mounting hole at its upper end; The sub-component is installed in conjunction with the mother component. The sub-component has a mounting position corresponding to the position of the mother component. The sub-component and the mother component are fastened together by bolts, and the positions of the sub-component and the mother component can rotate relative to each other left and right. The correction limiting bolts are installed in two sets on the left and right sides of the back plate of the sub-component and abut against the side plates of the mother component to limit the rotation angle between the mother component and the sub-component.

[0012] As a further improvement to the above technical solution: The mother panel includes a back plate and side plates. The back plate is hollow, and mounting holes are provided on both sides of the hollow section for mounting with the trackless drive.

[0013] The sub-component includes a back plate and a mounting column, which are integrally formed. The mounting column is hollow inside, and the mounting position is set in the mounting column in a column shape. The mounting position is set in the mounting column by at least five support plates. The back plate is provided with mounting holes for mounting with the device that needs to be driven.

[0014] The alignment connector also includes a buffer strip, which is located where the alignment limiting bolt abuts against the side plate of the mother part, i.e., it is snapped onto the edge of the side plate of the mother part, and is used to buffer during alignment.

[0015] Compared with the prior art, the beneficial effects of this utility model are: 1. Simple structure, easy to install and adjust: The mating installation of the mother and daughter components and the tightening of bolts make the installation process of the connecting parts simple and quick. The relative rotation between the daughter and mother components and the adjustment of the correction limit bolts make the correction operation of the trackless drive very convenient, without the need for complicated tools or professional knowledge.

[0016] 2. Achieve effective alignment correction: The relative rotation between the child and parent components compensates for minor deviations that may occur during installation or operation of the trackless drive. The alignment limit bolts and buffer shims precisely limit the alignment range and provide cushioning to prevent damage from over-adjustment or collisions.

[0017] 3. Improved working accuracy and stability: The effective correction function can ensure that the trackless drive always stays on the preset running track, thereby improving the operating accuracy and stability of the entire system and reducing the failure rate.

[0018] 4. Applicable to a variety of trackless drives: The connector is designed to be versatile and can be used with different types of trackless drives, thus expanding its application range. Attached Figure Description

[0024] In the following description, numerous specific details are set forth in order to provide a more thorough understanding of the present invention. However, it will be apparent to those skilled in the art that the present invention can be practiced without one or more of these details. In other instances, certain technical features well-known in the art have not been described in order to avoid confusion with the present invention.

[0025] like Figure 1-4 As shown, this embodiment provides a correction connector for a trackless drive, which mainly consists of a mother component 1, a daughter component 2, a correction limiting bolt 5, and a buffer strip 10. It can realize relative rotation between the mother component 1 and the daughter component 2 and limit the rotation angle, while providing buffer protection to correct deviations during the operation of the trackless drive.

[0026] Mother component 1: Structure of Mother Component 1: Mother Component 1 adopts an integral molding design, with the main body being the back plate 7 and the side plates 6 connected to both sides of the back plate 7.

[0027] Backplate 7: Backplate 7 is designed as a hollow structure, and its internal space is used to accommodate the mounting posts 8 of part 2. On both sides of the hollow space, mounting holes 4 are respectively provided. The size and shape of these mounting holes 4 are designed according to the actual mounting interface of the trackless drive, and are used to firmly fix the mother part 1 to the output end of the trackless drive.

[0028] Side plate 6: Side plate 6 extends along both sides of back plate 7, and its main function is to limit the rotation angle of sub-component 2. The outer surface of side plate 6 is relatively flat, and the inner surface forms a certain angle with back plate 7 so as to mate with a specific area of ​​mounting post 8 of sub-component 2.

[0029] Sub-component 2: Sub-component 2 structure: Sub-component 2 also adopts an integral molding design, mainly including back plate 7 and integrally molded mounting column 8.

[0030] Back plate 7: The back plate 7 of the sub-component 2 is provided with mounting holes 4. The size and shape of these mounting holes 4 are designed according to the mounting interface of the device to be driven (e.g., connecting rod, guide wheel, etc.) and are used to connect the sub-component 2 to the driven device.

[0031] Mounting Post 8: Mounting Post 8 extends vertically from the back plate 7 of Sub-component 2, and is hollow inside, for mating with the back plate 7 of Mother Component 1. The mounting position 3 of Mounting Post 8 is columnar and located inside Mounting Post 8. To ensure the stability and load-bearing capacity of Mounting Position 3, Mounting Position 3 is firmly connected to the inner wall of Mounting Post 8 by at least five support plates 9, forming a stable support structure. The outer surface of Mounting Post 8 is designed with grooves or bevels of a specific shape to abut against the side plate 6 of Mother Component 1 and the head of the correction and limiting bolt 5.

[0032] Assembly and installation: Installation Relationship: The mounting post 8 of sub-component 2 is inserted into the hollow space of the back plate 7 of mother component 1. The back plate 7 of sub-component 2 and the back plate 7 of mother component 1 are fastened together by bolts. The bolts pass through the mounting holes 4 of the back plate 7 of mother component 1 and the mounting holes 4 of the back plate 7 of sub-component 2, and are screwed into the corresponding nuts (not shown) to firmly connect the two together.

[0033] Relative rotation: Due to the bolt fastening method, the sub-component 2 can rotate left and right relative to the mother component 1 around the central axis of the bolt. This rotation allows the mother component 1 and sub-component 2 to adjust to a certain angle to correct deviations when slight lateral misalignment occurs during trackless drive operation.

[0034] Correction limits and buffers: Correction limiting bolts 5: Two sets of correction limiting bolts 5 are installed on the left and right sides of the back plate 7 of the sub-component 2. The heads of these bolts are designed to be cylindrical or spherical and have a certain extension length. They are screwed into the threaded holes on the back plate 7 of the sub-component 2, and the limiting angle can be precisely controlled by adjusting the screwing depth of the bolts.

[0035] Limiting principle: The head of the correction limiting bolt 5 abuts against both sides of the side plate 6 of the mother component 1. When the daughter component 2 rotates relative to the mother component 1, the bolt head contacts the side plate 6 of the mother component 1, thereby limiting the relative rotation angle between the mother component 1 and the daughter component 2. By setting the bolt position and screw-in depth in advance, a reasonable correction range can be set.

[0036] Buffer strip 10: Buffer strips 10 are pre-installed at the point where the side plate 6 of the mother component 1 abuts against the head of the correction limiting bolt 5. These buffer strips 10 can be made of rubber, polyurethane, or other elastic materials. They are snapped onto the edge of the side plate 6 of the mother component 1, or fixed by means of adhesive, slots, etc.

[0037] Buffering effect: When the trackless drive is correcting its alignment, the sub-component 2 needs to rotate. When the alignment limit bolt 5 contacts the side plate 6 of the mother component 1, the buffer strip 10 can absorb some of the impact energy and provide a buffering effect, avoiding direct metal-to-metal impact, reducing noise and vibration, and protecting the life of the connecting parts and related components.

[0038] Working principle: When the trackless drive experiences a slight left or right deviation during operation, the female component 1 connected to its output end will be subjected to a lateral force. Since the connection between the female component 1 and the female component 2 allows for relative rotation, the female component 2 will rotate to a certain extent according to the deviation angle of the female component 1. At this time, the correction limiting bolt 5 on the back plate 7 of the female component 2 will gradually contact the buffer strip 10 on the side plate 6 of the female component 1. As the deviation angle increases, the bolt will further contact the female component 1, eventually reaching the preset limit angle, preventing further deviation and thus correcting the travel path of the trackless drive. The buffer strip 10 provides a flexible connection during the correction process, absorbing impact and ensuring the smooth operation of the system.

[0039] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
