Abstract
Description
Technical Field
[0001] This application relates to the field of automotive processing and manufacturing technology, and in particular to auxiliary devices. Background Technology
[0002] In the process of making clay models, the clay layer needs to be applied to a specified thickness, and the application of clay is difficult to replace mechanically, so it is mostly done manually. The accuracy of the clay application thickness greatly affects the amount of clay used, labor time, and processing time, so it is necessary to control the accuracy of the clay application. Utility Model Content
[0003] Therefore, it is necessary to provide an auxiliary device and an automotive clay model to improve the accuracy of clay application.
[0004] This application provides an auxiliary device for an automotive clay model. The automotive clay model includes a bottom skeleton, a foam layer, and a clay layer connected sequentially along a first direction. The automotive clay model is disposed on one side of the auxiliary device along a second direction. The auxiliary device includes:
[0005] The operating component has a mounting portion, which is positioned in a preset position along a first direction; and
[0006] The detection component has a first end and a second end disposed opposite to each other along a second direction, the first end being fitted to the mounting portion;
[0007] Wherein, the first direction and the second direction are arranged perpendicular to each other, and at least one of the operating member and the detection member is configured to be movable along the second direction so that the second end can be moved along the second direction; the second end is used to assist in determining whether the current size of the sludge layer along the first direction is at the target size during the movement of the second end along the second direction.
[0008] In one embodiment, the first end of the detection element and the mounting portion are detachably connected.
[0009] In one embodiment, the detection element is movably connected to the mounting portion along a second direction.
[0010] In one embodiment, the operating member has a mounting groove along the second direction, and the detection member is movably inserted into the mounting groove along the second direction, the mounting groove constituting at least a portion of the mounting part.
[0011] In one embodiment, a limiting part is provided in the middle of the inner wall of the mounting groove, and a mating groove is opened on the detection piece along the second direction. The mating groove is movably inserted into the limiting part along the second direction.
[0012] In one embodiment, multiple mounting slots are provided along a first direction.
[0013] In one embodiment, the spacing between two adjacent mounting slots along the first direction is the same.
[0014] In one embodiment, the cross-sectional area of the second end increases along the direction pointing from the second end to the first end.
[0015] In one embodiment, the cross-sectional area of the second end gradually increases along the second direction pointing towards the second end.
[0016] In one embodiment, the cross-sectional shape of the second end is trapezoidal along the first direction; the cross-section of the second end is perpendicular to the first direction; and / or
[0017] Along the third direction, the cross-section of the second end is a right triangle; the cross-section of the second end is perpendicular to the third direction, and the third direction, the first direction, and the second direction are set perpendicular to each other.
[0018] The aforementioned auxiliary device is used for automotive clay models. Based on the required clay thickness, a preset position is located on the operating component, and a detection component is placed at that position. During the clay filling process, the auxiliary device is first placed close to the clay layer on the foam layer. The operator moves either the operating component or the detection component towards the clay layer in a second direction. If the detection component cannot contact the clay layer, it indicates that the clay thickness has not reached the preset thickness, and the operator needs to reapply clay until the detection component can contact the clay layer, thus completing the clay filling process. The entire process eliminates the need for manual visual judgment to determine whether the clay has reached the filling position, further improving the accuracy of clay filling.

However, this application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this application. Therefore, this application is not limited to the specific embodiments disclosed below.

Thus, a feature defined with "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this application, where the term "multiple" appears, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0032] Reference Figure 1 and Figure 2 , Figure 1 A schematic diagram of the structure of the auxiliary device 100 in some embodiments of this application is shown. Figure 2 Shown Figure 1 The diagram shows the structure of the auxiliary device 100 in contact with the clay layer Y. The auxiliary device 100 is used for an automotive clay model, which includes a bottom skeleton, a foam layer P, and a clay layer Y connected sequentially along a first direction F1, and the automotive clay model is located on one side of the auxiliary device 100 along a second direction F2.
[0033] Among them, car clay models are a type of car model in which designers present their creative ideas in a three-dimensional physical form. It is an important tool in the early stages of car design, used to showcase the car's exterior styling and interior layout, allowing designers and related personnel to intuitively understand the car's shape, proportions, lines, and other design elements. A car clay model consists of a base skeleton, a foam layer (P), and a clay layer (Y). The base skeleton is the basic supporting structure of the car clay model. It is usually made of metal or wood. The foam layer (P) mainly serves to fill and initially shape the car. Commonly used foam materials include polystyrene foam and polyurethane foam. Polystyrene foam is lightweight, easy to process, and can be quickly cut and shaped to form the general outline of the car. The clay layer (Y) is the key part of the car clay model, used to showcase the car's final appearance. Clay is a material with good plasticity, viscosity, and toughness. It can be used for detailed shaping on the foam layer (P) or the base skeleton, accurately representing the car's lines, curves, and details. The clay should be applied evenly and densely, avoiding layering or air bubbles.
[0034] During the application process, it's crucial to control the thickness of the clay layer. Generally, the thickness of the clay layer Y should be determined based on the size and complexity of the model. The thickness of the clay layer Y affects the overall stability of the model. If the clay layer Y is too thick, its increased weight may put excessive pressure on the underlying skeleton and foam layer P, causing the model to deform. This deformation may be more pronounced, especially if the model needs to be displayed or moved for extended periods. An appropriate clay layer Y thickness ensures that the model maintains its shape while remaining structurally stable and reliable. Furthermore, an excessively thick clay layer Y will make the waistline appear bulky, losing its original sharpness and fluidity; while an excessively thin layer may fail to fully express the desired line depth and three-dimensionality. Therefore, precise control of the clay application is essential.
[0035] Continue to refer to Figure 1 and Figure 2 The auxiliary device 100 provided in this application includes an operating component 1 and a detection component 2. The operating component 1 has a mounting portion 11, which is positioned in a preset position along a first direction F1. It is understood that the preset position is determined based on the required thickness of the sludge. "Operating component 1" refers to the component operated by the operator. The detection component 2 has a first end D1 and a second end D2 disposed opposite to each other along a second direction F2, with the first end D1 mating with the mounting portion 11, and the first direction F1 and the second direction F2 being perpendicular to each other. "Matching" refers to placing two or more mechanical components together so that they can cooperate and contact each other in a predetermined manner. Specifically, in this application, this means that the mounting portion 11 and the first end D1 can contact each other. The first end D1 can be fixedly connected to the mounting portion 11, and the first end D1 can also move relative to the mounting portion 11, all within the scope of protection of this application. This allows the detection component to be positioned in the preset position.
[0036] Next refer to Figure 1 and Figure 2 At least one of the operating element 1 and the detection element 2 is configured to move along the second direction F2, so that the second end D2 can move along the second direction F2. During the movement of the second end D2 along the second direction F2, it assists in determining whether the current size of the sludge layer Y along the first direction F1 is at the target size. The configuration of at least one of the operating element 1 and the detection element 2 to move along the second direction F2 includes the case where only the operating element 1 is configured to move along the second direction F2, the case where only the detection element 2 is configured to move along the second direction F2, and the case where both the operator and the detection element 2 are configured to move along the second direction F2.
[0037] The operator can move the second end D2 in the second direction F2 by manipulating the detection element 2 or the operation element 1, so that the second end D2 can approach the car clay model located on the side of the auxiliary device 100 along the second direction F2. Whether the second end D2 can contact the clay layer Y is determined to determine whether the current size of the clay layer Y along the first direction F1 is within the target size.
[0038] Thus, a preset position can be found on the operating component 1 according to the required thickness of the sludge, and the detection component 2 can be placed at that preset position. During the sludge application process, the auxiliary device 100 is first placed close to the sludge layer Y on the foam layer P. The operator moves either the operating component 1 or the detection component 2 along the second direction F2 towards the position of the sludge layer Y. If the detection component 2 cannot contact the sludge layer Y, it means that the thickness of the sludge has not reached the preset thickness, and the operator needs to apply the sludge again until the detection component 2 can contact the sludge layer Y to complete the sludge application. When creating the sludge model, in order to effectively save sludge and reduce labor costs, strict supervision is implemented on the thickness and accuracy of the sludge layer. Technical measures include precise CNC preprocessing of the foam underlayer to ensure that the accuracy of the sludge layer is the key control point. However, due to significant inconsistencies in the manual control accuracy among operators, and the lack of a clear accuracy measurement standard during sludge application, it is difficult to accurately measure the thickness of the sludge layer. This application employs an auxiliary device to strictly monitor the thickness and accuracy of the clay layer during clay model creation, aiming to effectively conserve clay and reduce labor costs. Technical measures include precise CNC pre-processing of the foam substrate, with ensuring the accuracy of the clay layer being a key control point. However, significant inconsistencies exist among operators in manually controlling precision, and a lack of a clear precision measurement standard during clay application makes accurate measurement of the clay layer thickness difficult. This application addresses this issue by using an auxiliary device, eliminating the need for manual visual judgment of whether the clay has reached the filling position, further improving the accuracy of clay application.
[0039] The movement of the driving component 1 and the detection component 2 can be manually operated by the operator or controlled by an electronic control system. The detection component 2 can be configured as a laser emitter, which determines whether the sludge layer Y has filled to the required height by whether it blocks the laser beam.
[0040] In some embodiments of this application, reference continues to be made to... Figure 1 and Figure 2 The first end D1 of the detection component 2 and the mounting part 11 are detachably connected. There are many ways to make a detachable connection, which are not limited here, such as threaded connection, snap-fit, etc. When the first end D1 and the mounting part 11 are detachably connected, it is convenient to maintain the detection component 2 and the operating component 1, and different sizes and models of detection components 2 can be replaced and set on the operating component 1 to suit different detection scenarios.
[0041] In some other embodiments, the connection may be non-detachable. This makes the connection between the detection element 2 and the operating element 1 more stable, increases the risk of the detection element 2 shaking during detection, and further improves the accuracy of the detection.
[0042] In some embodiments of this application, the detection element 2 is movably connected to the mounting portion 11 along the second direction F2.
[0043] Thus, the detection element 2 and the mounting part 11 can move relative to each other along the second direction F2. The movement of the second end D2 along the second direction F2 can be achieved by moving the detection element 2 or by moving the mounting part 11, further improving the convenience of detection.
[0044] In some embodiments of this application, reference continues to be made to... Figure 1 and Figure 2 The operating member 1 has a mounting groove C1 along the second direction F2, and the detection member 2 is movably inserted into the mounting groove C1 along the second direction F2. The mounting groove C1 constitutes at least part of the mounting part 11.
[0045] The detection element 2 can be movably connected to the operating element 1 along the second direction F2 by simply providing a mounting slot C1. The structure is simple and easy to manufacture. The shape of the mounting slot C1 can be wavy or straight, as long as it can fit the detection element 2. There are no specific limitations on the number and shape of the mounting slots C1.
[0046] In some other embodiments, the detection element 2 can also be movably disposed in the mounting part 11 along the second direction F2 by setting a slide rail slider.
[0047] In some embodiments of this application, reference continues to be made to... Figure 1 and Figure 2 and in conjunction with reference Figure 3 , Figure 3 Shown Figure 1 The diagram shows the structure of the detection component 2. A limiting part X is provided in the middle of the inner wall of the mounting groove C1. A mating groove C2 is opened on the detection component 2 along the second direction F2. The mating groove C2 is movably inserted into the limiting part X along the second direction F2.
[0048] Thus, the limiting part X makes the connection between the detection element 2 and the operating element 1 more stable. It is understandable that compared to directly inserting the operating element 1 into the mounting part 11, this increases the contact area between the operating element 1 and the mounting part 11, resulting in greater friction between the operating element 1 and the mounting part 11, making the operating element 1 more stable and reliable in its installation within the mounting part 11. Furthermore, the limiting part X is located in the middle of the mounting groove C1, providing precise positioning and a reliable support point for the connection between the detection element 2 and the operating element 1. When the operating element 1 experiences vibration, impact, or other external interference during operation, the limiting part X in the middle can effectively disperse the force, further reducing the risk of excessive displacement or shaking between the detection element 2 and the operating element 1, thereby ensuring the stability of the connection. Moreover, the limiting part X in the middle allows the force to be transmitted and dispersed along a more reasonable path. Compared to the potential for localized stress concentration that may result from direct insertion, the limiting part X in the middle can evenly distribute the force around the connection structure. The structure, shape, and size of the limiting part X are not limited, and the shape and size of the mating groove C2 are also not limited, as long as they are adapted to the limiting part X.
[0049] Continue to refer to Figure 3 Specifically, in this application, the mounting groove C1 is a rectangular groove, and the limiting part X is approximately square in shape. The square shape has a relatively regular and uniform force-bearing surface. When the detection component 2 is installed in the rectangular groove, regardless of whether the force comes from the horizontal or vertical direction, the square limiting part X can evenly distribute the force to each surface. Furthermore, the square structure is relatively simple, making it easier to achieve high-precision production during manufacturing and processing, whether using machining, injection molding, or other manufacturing processes.
[0050] In some embodiments of this application, multiple mounting slots C1 are provided along the first direction F1.
[0051] Thus, by providing more mounting slots C1 for the installation of the test piece 2, it is possible to install the test piece 2 in different preset positions. This can accommodate the different requirements of different sludge models for the thickness of the sludge layer Y. When different sludge models need to be tested, the test can be performed by installing the test piece 2 in different mounting slots C1.
[0052] In some embodiments of this application, reference continues to be made to... Figure 1 , Figure 2 as well as Figure 3 The spacing between two adjacent mounting slots C1 along the first direction F1 is the same.
[0053] In this way, as many mounting slots C1 as possible can be set on an operating component 1, and the spacing between two adjacent mounting slots C1 along the first direction F1 is the same, which makes the slots on the operating component 1 more uniform, the force on the operating component 1 more balanced, and further improves the strength of the structure of the operating component 1.
[0054] In some embodiments of this application, the cross-sectional area of the second end D2 increases along the direction F2 pointing to the first end D1.
[0055] The term "increasing trend" can include phased increases, such as an initial increase followed by a period of no change, and then an increase again; it can also include continuous increases, such as a consistent rate of increase or an initial rapid increase followed by a slower increase. Taking an increasing trend of an initial increase followed by a period of no change, and then an increase again as an example, the increasing trend can be divided into three phases: the initial increase phase, the period of no change, and the period of increase again.
[0056] Thus, the second end D2 is designed to be sharp. After the second end D2 contacts the clay layer Y, sliding the second end D2 along the third direction F3 will leave a mark on the clay layer Y. This allows us to determine whether the clay layer Y has been filled to the specified thickness by observing whether there are scraping marks on it. Furthermore, these lines are lightly drawn on the clay layer Y as a reference for scraping and shaping. This makes it clear which parts need special attention and which parts should be preserved when scraping the clay, improving work efficiency and the accuracy of shape shaping.
[0057] In some embodiments of this application, reference continues to be made to... Figure 1 , Figure 2 and Figure 3 Along the second direction F2 pointing towards the second end D2, the cross-sectional area of the second end D2 gradually increases. This represents the case where the cross-sectional area continuously increases at a constant rate. Setting the cross-sectional area to continuously increase makes the second end D2 increasingly sharper as it moves further away from the first end D1. Setting the rate of cross-sectional increase to be consistent makes the manufacturing of the second end D2 easier.
[0058] In some embodiments of this application, reference continues to be made to... Figure 1 , Figure 2 and Figure 3 Along the first direction F1, the cross-section of the second end D2 is trapezoidal in shape and perpendicular to the first direction F1; and / or, along the third direction F3, the cross-section of the second end D2 is a right triangle in shape and perpendicular to the third direction F3. The third direction F3, the first direction F1, and the second direction F2 are set perpendicular to each other.
[0059] When the cross-section of the second end D2 along the first direction F1 is trapezoidal and perpendicular to the first direction F1, the isosceles trapezoidal cross-section allows for a relatively uniform distribution of stress across the entire cross-section when the test piece 2 is subjected to tension or compression. Compared to some irregular shapes, the two hypotenuses and the top and bottom edges of the isosceles trapezoid work together to disperse and transfer external forces. Specifically, in this application, the trapezoid is an isosceles trapezoid. From a manufacturing perspective, the isosceles trapezoid is a relatively regular and simple geometric shape. In machining processes, whether using cutting, forging, or casting, it is easier to achieve using standardized molds or tools. When the cross-section of the second end D2 along the third direction F3 is a right triangle and perpendicular to the third direction F3, and the third direction F3, the first direction F1, and the second direction F2 are all perpendicularly arranged, the angle between the hypotenuse and the right-angled side of the right triangle gives it better resistance to shear forces. When the sludge layer Y comes into contact with the test piece 2, and a transverse shear force acts on the second end D2, the right-angled triangle shape can convert the shear force into pressure and tension along the right-angled sides, resisting shear deformation through stress balance within the material. This extends the service life of the test piece 2.
[0060] The above-mentioned "along the first direction F1, the cross-section of the second end D2 is trapezoidal in shape and the cross-section of the second end D2 is perpendicular to the first direction F1" and "along the third direction F3, the cross-section of the second end D2 is right-angled triangle and the cross-section of the second end D2 is perpendicular to the third direction F3, and the third direction F3, the first direction F1 and the second direction F2 are set perpendicular to each other" can be arbitrarily combined according to the actual situation.
[0061] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
[0062] The above embodiments merely illustrate several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
