Description

Technical Field

[0001] This utility model provides a mounting base, and in particular relates to a mounting base for a 3D scanner for modeling ancient buildings. Background Technology

[0002] In the field of ancient building modeling, the mounting base of a 3D scanner is a crucial device used to support and fix the scanner, ensuring its stable operation during data acquisition and allowing for adjustment of the scanning angle according to actual needs. The base provides a reliable support foundation, ensuring precise scanner positioning and accurate acquisition of 3D data about the ancient building, thus laying the foundation for subsequent modeling, restoration, and conservation work.

[0003] Existing mounting bases for 3D scanners used for ancient building modeling typically consist of a simple flat base and a clamping mechanism. The flat base connects to the support surface, while the clamping mechanism secures the scanner. However, these bases have significant shortcomings: First, the flat base only has fixing holes, making it unsuitable for different support surfaces and installation scenarios, resulting in poor installation flexibility. Second, the clamping mechanism is mostly a single fixing method, lacking adjustment mechanisms, making it difficult to securely clamp different scanner models, and it offers no protection for the scanner casing. Third, the connections between the base components are fixed, lacking omnidirectional adjustment capabilities, making it difficult to meet the needs of multi-directional scanning angle adjustments in complex environments, and the connection stability is poor, easily causing shaking during scanning and affecting the accuracy of the scanned data. Utility Model Content

[0004] To address the aforementioned issues, this application provides a mounting base for a 3D scanner for ancient building modeling, resolving problems such as poor installation compatibility, unstable clamping, inconvenient angle adjustment, and poor stability, thereby ensuring the accuracy of the scanned data.

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a mounting base for a 3D scanner for modeling ancient buildings, comprising:

[0006] The top mounting plate is flat and has several mounting holes and long slots on its surface to accommodate different installation requirements. It is used to connect with the bearing surface or other compatible structures and provides a top support base for the entire mounting base.

[0007] The intermediate connecting frame is connected to the bottom of the top mounting plate and includes a horizontal connecting part and a vertical connecting part that are perpendicular to each other. The horizontal connecting part is used to receive and fix the force transmitted from the top mounting plate, and the vertical connecting part is provided with a connecting interface for connecting the lower structure. Its shape is a frame structure with a certain thickness to ensure structural strength and connection stability.

[0008] The bottom clamping assembly is connected to the intermediate connecting frame through the connection interface of the intermediate connecting frame. It includes a fixed clamping component and a movable clamping component that cooperate with each other. The fixed clamping component is fixedly connected to the connection interface of the intermediate connecting frame and has a semi-enclosed structure. The movable clamping component can move relative to the fixed clamping component in a specific direction. Together, they form a clamping space for clamping the main body of the 3D scanner. The clamping assembly is provided with a locking structure, such as a locking bolt or a buckle, for locking the position of the movable clamping component and ensuring clamping stability.

[0009] Preferably, the top mounting plate, intermediate connecting frame, and bottom clamping assembly are connected by a shaft connection structure to achieve rotation or angle adjustment in different directions. Specifically, a horizontal pivot is provided between the horizontal connection part of the top mounting plate and the intermediate connecting frame, allowing the intermediate connecting frame to rotate relative to the top mounting plate in a horizontal plane; a vertical pivot is provided between the vertical connection part of the intermediate connecting frame and the fixed clamping part of the bottom clamping assembly, allowing the bottom clamping assembly to rotate relative to the intermediate connecting frame in a vertical plane. Through the cooperation of the horizontal and vertical pivots, multi-directional angle adjustment and universal installation adaptation of the 3D scanner can be achieved. At the same time, the shaft connection structure of each connection part is provided with limiting and fastening structures for positioning and ensuring stability after connection, such as limiting protrusions and grooves, fastening nuts, etc., to ensure the stability of the base as a whole and the clamped scanner after installation.

[0010] Preferably, the elongated grooves of the top mounting plate are parallel through grooves, and their length direction extends along the length direction of the top mounting plate to accommodate mounting connectors with different spacing, thereby improving installation adaptability.

[0011] Preferably, the clamping surfaces of the fixed clamping member and the movable clamping member of the bottom clamping assembly are provided with an anti-slip buffer layer, such as a rubber pad, to increase clamping friction, protect the scanner housing, and improve clamping stability and protection for the scanner.

[0012] Preferably, both the horizontal and vertical rotating shafts are made of metal and have been treated with anti-rust agents, such as zinc plating, to improve their corrosion resistance and service life, and to ensure long-term stable rotational connection.

[0014] This device serves as the mounting base for a 3D scanner for ancient building modeling. A flat top mounting plate with mounting holes and elongated slots forms a top support foundation that connects to the load-bearing surface or an adaptable structure, accommodating various installation needs. The intermediate connecting frame receives and fixes the force transmitted from the top mounting plate via mutually perpendicular horizontal connecting parts, while a frame-type vertical connecting part with connection interfaces connects to the lower structure, ensuring structural strength and connection stability. The bottom clamping assembly utilizes fixed clamping parts and relatively movable clamping parts to achieve stable clamping of the 3D scanner body. In the shaft connection structure, a horizontal pivot between the top mounting plate and the horizontal connecting part of the intermediate connecting frame allows the intermediate connecting frame to rotate horizontally relative to the top mounting plate, while the intermediate connecting frame vertically... The vertical pivot between the direct connection and the bottom clamping assembly allows the bottom clamping assembly to rotate vertically relative to the intermediate connecting frame, enabling multi-directional angle adjustment and universal installation adaptation. The limiting and fastening structures of each axis connection structure ensure stable connection. The parallel arrangement of the top mounting plate and the elongated grooves extending along the plate length accommodate mounting connectors with different spacing, improving installation adaptability.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0022] It should be noted that the terms "vertical," "horizontal," "up," "down," "left," "right," and similar expressions used in this article are for illustrative purposes only and do not represent the only possible implementation.

[0023] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains; the terminology used herein in the description of this invention is for the purpose of describing particular embodiments only and is not intended to limit the invention; the term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0024] like Figure 1 and Figure 2 As shown, a mounting base for a 3D scanner for modeling ancient buildings includes a flat top mounting plate 1 with mounting holes and elongated grooves, serving as the top support foundation and bearing surface; a middle connecting frame 2 containing vertical and horizontal connecting parts 21 and vertical connecting parts 22 (with connecting interfaces and a frame structure), which supports the top mounting plate 1 and connects to the lower part; and a bottom clamping assembly 3 composed of fixed clamping parts 31 (semi-enclosed, connected to the middle connecting frame interface) and movable clamping parts 32 (relatively movable, with a locking structure), which together clamp the scanner body 33. The top mounting plate 1, middle connecting frame 2, and bottom clamping assembly 3 are angle-adjustable via an axial connection structure 4: a horizontal pivot is provided between the top and the middle horizontal connecting parts, allowing the middle to rotate horizontally relative to the top; a vertical pivot is provided between the middle vertical connecting parts and the bottom fixed clamping parts, allowing the bottom to rotate vertically relative to the middle, achieving universal adaptation. The axial connection structure 4 has a limiting and fastening structure to ensure stability.

[0025] In this implementation scheme, the mounting holes and elongated grooves of the top mounting plate 1 can accommodate connectors and bearing surfaces of different specifications, greatly improving installation flexibility. The frame structure and vertical connection of the middle connecting frame 2, relying on the principle of triangular stability, distribute the force and enhance the overall structural strength. In the bottom clamping assembly 3, the cooperation between the fixed clamping part 31 and the movable clamping part 32, along with the locking structure and anti-slip buffer layer, can not only securely clamp different models of scanners but also prevent wear on the outer shell. The horizontal and vertical rotating shafts of the shaft connection structure 4, along with the limiting and fastening structure, can achieve universal angle adjustment while increasing friction and limiting the rotation range, ensuring the stability of the device in complex scanning environments. The innovative combination of these components effectively solves the problems of poor installation adaptability, unstable clamping, limited angle adjustment, and insufficient stability of traditional bases, significantly improving the accuracy and efficiency of 3D scanning of ancient buildings.

[0026] like Figure 2 and Figure 3 As shown, the top mounting plate 1 of the mounting base has a long, parallel groove that extends along the length of the plate to accommodate connectors with different spacing, improving adaptability. The clamping surfaces of the fixed and movable clamping parts of the bottom clamping assembly 3 are provided with an anti-slip buffer layer (such as a rubber pad) to increase friction, protect the scanner housing, and improve clamping stability and protection. The horizontal and vertical rotating shafts are made of metal and are treated with anti-rust measures (such as galvanizing) to improve corrosion resistance and lifespan, ensuring long-term stability of the rotating connection.

[0027] In this implementation plan, the stability of this device is mainly achieved through the synergistic effect of multiple factors, including structural design, mechanical balance, and material properties. By employing a reasonable physical structural layout and applying physical properties, the stability of the 3D scanner for ancient building modeling is ensured after installation, as detailed below:

[0028] Stability of structural design

[0029] Triangular stability principle: The intermediate connecting frame 2 adopts a frame structure, with its mutually perpendicular horizontal connecting parts 21 and vertical connecting parts 22 forming a stable structure resembling a triangle. In mechanics, triangles possess stability; when subjected to external forces, the three sides and three angles of a triangle constrain each other, uniformly distributing the external force. According to the principles of statics, when an object is in equilibrium under the action of forces, it must satisfy the force equilibrium equations ∑Fx=0, ∑Fy=0, ∑M=0 (where ∑Fx is the resultant force in the horizontal direction, ∑Fy is the resultant force in the vertical direction, and ∑M is the resultant moment). The frame structure, through the combination of multiple triangular units, can effectively resist external forces from different directions, distributing the force to various connection points, avoiding excessive local stress that could lead to structural deformation, thereby ensuring the overall structural stability.

[0030] Optimized center of gravity distribution: The layout of the top mounting plate 1, the intermediate connecting frame 2, and the bottom clamping assembly 3 is rationally designed to lower the center of gravity of the entire device as much as possible and place it in the center of the base. According to the principle of center of gravity, the lower and closer the center of gravity of an object is to the center, the higher its stability. By placing the heavier components (such as the frame structure of the intermediate connecting frame 2) in the middle position and making the weight distribution of the bottom clamping assembly 3 symmetrical, the center of gravity of the device is lowered, enhancing its resistance to tipping. When the device is subjected to an external torque, the torque generated by gravity can balance the external torque. According to the torque balance formula M=F×d (where M is the torque, F is the force, and d is the lever arm), the reaction torque generated by gravity can prevent the device from rotating and maintain stability.

[0031] Stability of connection method

[0032] Shaft connection structure limiting and fastening: In shaft connection structure 4, the horizontal and vertical rotating shafts not only achieve multi-directional angle adjustment, but also ensure connection stability through limiting and fastening structures (such as the matching of limiting protrusions and grooves, fastening nuts, etc.). The limiting structure restricts the rotation range of each component, preventing excessive rotation from causing the connection to loosen; the fastening nut increases the friction between the shaft and the connecting components by applying preload. According to the friction formula f = μ × N (where f is the friction force, μ is the coefficient of friction, and N is the normal force), the increase in preload increases the normal force N, thereby increasing the friction force f, effectively preventing relative sliding of components due to external forces during rotation, and ensuring the reliability of the connection.

[0033] Stable clamping connection: The fixed clamping member 31 and the movable clamping member 32 of the bottom clamping assembly 3 form a stable clamping force through a locking structure (such as locking bolts, buckles, etc.). When the locking structure is engaged, it applies uniform pressure to the scanner body 33, ensuring a tight fit between it and the clamping member. According to the principle of action and reaction, the clamping force on the scanner and the reaction force on the clamping member are equal in magnitude and opposite in direction. This interaction force prevents the scanner from shaking during scanning. Simultaneously, the anti-slip buffer layer (such as a rubber pad) increases the coefficient of friction μ of the clamping surface, further enhancing the friction force f and ensuring the scanner is securely clamped.

[0034] The contribution of material properties to stability

[0035] High strength and rigidity of metal shafts: Both the horizontal and vertical shafts are made of metal, which possesses high strength and rigidity, enabling it to withstand significant external forces without easily deforming. According to Hooke's Law F = k × Δx (where F is the external force, k is the elastic coefficient, and Δx is the deformation), the elastic coefficient k of metal is relatively large. Therefore, when subjected to external forces, the resulting deformation Δx is smaller, ensuring the stability of the shaft connection structure under stress and preventing device wobbling due to shaft deformation.

[0036] Material strength of the frame structure: The frame structure of the intermediate connecting frame 2 is made of high-strength material, which has high compressive, tensile and bending strength. When subjected to the force transmitted from the top mounting plate 1 and the reaction force of the bottom clamping component 3, it can maintain the integrity of the structure and prevent plastic deformation or fracture, thereby ensuring the stability of the entire device.

[0037] It should be noted that the moving clamp 32 is made of aluminum alloy, which ensures sufficient strength while reducing the overall weight. Its anti-slip buffer layer can be made of nitrile rubber. Utilizing the good wear resistance and high coefficient of friction of this rubber, when locking the scanner with locking bolts (common hexagonal bolts), it can firmly fix the equipment and effectively prevent wear on the equipment surface. When adjusting the scanning angle, the operator can use existing calibration equipment such as a laser level, along with the horizontal and vertical rotating shafts made of 45# steel that have been quenched in the shaft connection structure 4. Through the precise cooperation of the limiting protrusions and grooves, the horizontal and vertical angles of the 3D scanner can be quickly and accurately calibrated. After calibration, nuts (such as high-strength hexagonal nuts) are used for further tightening to ensure that the device is stable and does not shake during the scanning process, thereby efficiently and accurately completing the data acquisition work for ancient building modeling.

[0038] Although the present invention has been disclosed above with reference to preferred embodiments, it is not intended to limit the present invention. Any person skilled in the art can make various modifications and alterations without departing from the spirit and scope of the present invention. Therefore, the scope of protection of the present invention should be determined by the claims.
