Description

Technical Field

[0001] The present application relates to the technical field of vehicle parts manufacturing, and specifically to a manufacturing method and equipment for integrally molding vehicle motion sample parts and an air-conditioning window structure. Background Art

[0002] Sport components in vehicles include smart grilles, air conditioning vents, glove boxes, storage boxes, and rotary gear shifts. In automotive projects, the primary method for manufacturing sport components is to separately manufacture their individual components through processes such as mold casting, 3D printing, and CNC machining. These components are then assembled together to form a physical assembly. This manufacturing approach has the following disadvantages: Manufacturing sport components involves a wide range of processes, including mold design / manufacturing, casting, 3D printing, and CNC machining. The entire manufacturing approach requires significant manpower and equipment investment, resulting in a low input-output ratio, high manufacturing difficulty, and a long production cycle. During the physical assembly of sport components, specialized fixtures are typically required due to the large number and complexity of their components. This makes the entire assembly process challenging and requires high-level technical expertise from the technicians. This leads to low manufacturing efficiency, long assembly cycles, and high component wear.

[0003] Existing methods for conveniently manufacturing air conditioner vents typically use mold casting and 3D printing to create individual components, which are then assembled into the entire vent. This process involves numerous steps and requires significant manpower and equipment resources. This method has the disadvantages of requiring numerous steps, difficult assembly, and a long production cycle.

[0004] Therefore, the existing situation and technology still need to be improved and developed. Summary of the Invention

[0005] In view of the above-mentioned deficiencies in the prior art, the purpose of this application is to provide a manufacturing method, equipment and air-conditioning window structure for one-piece molding of vehicle motion samples, so as to solve the problems in the prior art of vehicle motion samples having many manufacturing process steps, great assembly difficulty and long manufacturing cycle.

[0006] The technical solutions of the present invention are as follows:

[0007] In a first aspect, the present application proposes a method for manufacturing a vehicle motion sample integrally formed, the manufacturing method comprising the steps of:

[0008] Obtaining digital part models of the motion sample, and combining the digital part models into different digital fixed parts;

[0009] Combine different digital fixtures, set matching parameters according to relative motion relationships, and obtain matching digital fixtures with matching clearances;

[0010] A digital support is provided on the digital fixing part, and a matching digital fixing part is connected through the digital support to obtain a digital model of an integral motion sample;

[0011] The digital model of the integral motion sample is 3D printed to obtain a physical object of the integral motion sample, and the physical object of the integral motion sample is immersed to dissolve the support part to obtain the motion sample, wherein the support part is obtained by 3D printing a digital support part.

[0012] According to the above technical means, during the digital design stage, digital part models whose positions remain unchanged during use are combined to form an integral digital fixture, which is then combined into different digital fixtures according to the relative motion relationship. Then, different digital fixtures are assembled according to the functional structure of the motion sample, and the matching parameters are set according to the relative motion relationship, so that the relative motion between the different digital fixtures can be achieved. Then, by setting digital support members on the digital fixture to support different parts, the matching clearance between the different digital fixtures can be maintained during the 3D printing process. The integral motion sample formed after 3D printing is soaked to dissolve the support members, thereby obtaining a motion sample with retained matching clearance. In this way, the motion sample can be obtained directly through a single 3D printing process, and the relative motion relationship between the different digital fixtures is well preserved during the 3D printing process, so that no additional assembly is required, which greatly simplifies the production and assembly steps and shortens the production cycle.

[0013] In conjunction with the first aspect, in certain implementations of the first aspect, the step of combining different digital fixtures, setting fitting parameters according to relative motion relationships, and obtaining a digital motion sample model with a fitting clearance includes:

[0014] Obtaining the outer surface of the embedded component in the matching digital fixture, and offsetting the outer surface to obtain a cutting surface;

[0015] The outer cover component of the matching digital fixture is cut off by the cutting surface, so as to form a matching gap between the matching digital fixtures.

[0016] According to the above technical means, a cutting surface is generated by offsetting the surface of the embedded component of the matching digital fixture, and the outer shell is cut off using the cutting surface. In this way, the fitting clearance between the matching digital fixtures can not only meet the relative motion requirements, but also standardize the forming of the fitting clearance, making the forming design of the fitting clearance more efficient.

[0017] In conjunction with the first aspect, in certain implementations of the first aspect, in the step of removing the outer cover component of the matching digital fixture by cutting the surface to form a fitting gap between the matching digital fixtures:

[0018] Determine the fit clearance based on the slice thickness, equipment single layer compensation, and equipment accuracy error, where:

[0019] 2(T+C)+E≥G≥T+C+2E;

[0020] Among them, T is the slice thickness, C is the single-layer compensation of the equipment, E is the absolute value of the equipment accuracy error, and G is the single-side distance of the fitting clearance.

[0021] According to the above technical approach, by using the aforementioned unilateral distance of the fitting clearance to offset the cutting surface, the fitting clearance formed between the matching digital fixtures does not interfere with their motion, thereby maintaining a stable kinematic relationship between the various physical components of the manufactured motion prototype, thereby improving the structural stability of the entire motion prototype. Furthermore, by limiting the upper limit of the fitting clearance, the structural strength of the outer cover component removed from the matching digital fixture can be guaranteed.

[0022] In conjunction with the first aspect, in certain implementations of the first aspect, the steps of obtaining an outer surface of an embedded component in a matching digital fixture and offsetting the outer surface to obtain a cutting surface include:

[0023] When the outer cover is placed on the inner part and slides, the outer surfaces of the two opposite sides of the inner part are extracted and offset by a single side distance to obtain cutting surfaces on both sides of the inner part;

[0024] When the outer cover component is sleeved on the inner cover component and rotated, the outer circular surface of the inner cover component is extracted and unilaterally offset by a unilateral distance to obtain a cutting surface surrounding the outer side of the inner cover component.

[0025] According to the above technical means, the above two cutting methods can keep the single-side distance of the cutting uniform, thereby ensuring the structural stability of the structural part after the cutting.

[0026] In conjunction with the first aspect, in certain implementations of the first aspect, in the step of providing a digital support member on a digital fixture and connecting a matching digital fixture via the digital support member to obtain a digital model of an integral motion sample:

[0027] The digital support component includes a mesh base and a top protrusion, and the thickness of the mesh base decreases stepwise along the height direction.

[0028] According to the above technical means, a mesh base is used for support, which has stable support, and the top convex points are used for fixation. While achieving the supporting function, it has little impact on the structure of the digital fixing part to which it is connected.

[0029] In combination with the first aspect, in certain implementations of the first aspect, the periphery of the mesh base is retracted inwardly by 5 mm for every 50 mm increase in the height of the mesh base.

[0030] According to the above technical means, the thickness of the digital support part gradually decreases with the increase of height, making the support structure more stable, thereby achieving stable support for the connected digital fixing parts and avoiding structural collapse and dimensional deformation during the 3D printing process.

[0031] In combination with the first aspect, in certain implementations of the first aspect, the support side length of the bottom of the mesh base is

[0032] Where H is the distance from the support point of the digital support and the digital fixing part to the printing plane, To round up;

[0033] The support side length of the top layer of the mesh base is 5 mm, and the support height of the top layer of the mesh base is:

[0034] When the remainder of H / 50 is greater than 3,

[0035] When the remainder of H / 50 is less than or equal to 3, H 顶 =50+remainder-3; where To round down.

[0036] With this technical approach, the support side length decreases as the height of the digital support increases, facilitating the formation of stable support at the top bump. Furthermore, during the post-3D printing soaking process to dissolve the support, the support quickly fuses from the upper end of the mesh base, allowing the actual moving part to quickly detach from the support, improving the efficiency of the dissolution process and further enhancing production and processing efficiency.

[0037] In conjunction with the first aspect, in certain implementations of the first aspect, in the step of 3D printing the digital model of the integral motion sample to obtain a physical object of the integral motion sample:

[0038] The support material and the motion sample material are printed simultaneously through a dual-nozzle printing system, wherein the support material is a soluble material.

[0039] According to the above technical means, simultaneous printing through a dual-nozzle printing system can enable the digital support part and the digital fixing part to be formed with different materials, which is conducive to the removal of the printed support part material by dissolution.

[0040] In conjunction with the first aspect, in certain implementations of the first aspect, after the steps of obtaining digital part models of the moving sample and combining the digital part models into different digital fixed parts, the method further includes:

[0041] Different digital fixtures are classified according to their functions to form different digital function modules, wherein a digital function module contains multiple digital fixtures.

[0042] According to the above technical means, different functional modules can be divided according to the fixed support function, lateral movement function and longitudinal movement function. In this way, different digital fixings can be classified, making the part design process more standardized. Different functional modules can be designed synchronously for collaborative work and finally assembled and combined, thus ensuring the smoothness of the part design process and improving work efficiency.

[0043] In conjunction with the first aspect, in certain implementations of the first aspect, when manufacturing an air outlet frame structure for an air conditioner, in the step of classifying different digital fixings according to their functions to form different digital functional modules, wherein the digital functional module contains multiple digital fixings:

[0044] Different digital function modules include: dial module, blade module and main body module;

[0045] Wherein: the multiple digital fixing parts in the dial button module include: a dial button, a shift fork, a shift piece and a limiter;

[0046] The multiple digital fixed parts in the blade module include: main blade, auxiliary blade, blade linkage rod;

[0047] The multiple digital fixing parts in the main module include: a decorative cover, a paddle shaft bracket, and a shell. The paddle shaft bracket is composed of a paddle shaft and a shaft frame, wherein the paddle shaft and the shaft frame are digital part models.

[0048] According to the above technical means, when manufacturing the air-conditioning outlet frame structure, the digital part models of the air-conditioning outlet frame structure are divided according to their functions, making the design logic clearer, the design process more standardized, and improving the structural design efficiency of the air-conditioning outlet frame.

[0049] In conjunction with the first aspect, in certain implementations of the first aspect, in the step of combining different digital fixtures, setting matching parameters according to relative motion relationships, and obtaining matching digital fixtures with matching clearances:

[0053] According to the above technical means, the matching relationship between the digital part models is not easily confused, the movement relationship between the printed objects is guaranteed to be correct, and the function of the manufactured air-conditioning outlet frame structure remains stable.

[0054] In conjunction with the first aspect, in certain implementations of the first aspect, in the blade module, in the steps of rotatably assembling the rotating shaft of the main blade and the blade linkage rod, and rotatably assembling the rotating shaft of the auxiliary blade and the blade linkage rod:

[0055] A shaft shoulder structure having a diameter greater than that of the connecting hole of the blade linkage rod is provided on the top of the rotating shaft of the main blade and the top of the rotating shaft of the auxiliary blade.

[0056] According to the above technical means, a shoulder structure is designed directly on the rotating shaft to prevent the blade linkage rod from falling out of the rotating shaft of the blade, thereby realizing the limiting function. At the same time, no additional assembly parts need to be added after the product is processed, which saves assembly time and improves production efficiency.

[0057] In conjunction with the first aspect, in certain implementations of the first aspect, in the step of determining the fitting clearance based on the slice thickness, the device single layer compensation amount, and the device precision error:

[0058] The unilateral distance between the paddle and the button is 0.15 to 0.3 mm, the unilateral distance between the fork and the button is 0.25 to 0.4 mm, and the unilateral distance between the stopper and the paddle is 0.25 to 0.4 mm.

[0059] The single-side distance between the main blade's rotating shaft and the connecting hole of the blade linkage rod is 0.25-0.4 mm, and the single-side distance between the auxiliary blade's rotating shaft and the connecting hole of the blade linkage rod is 0.25-0.4 mm.

[0060] According to the above technical means, the use of the above gap can ensure the smoothness of the movement process of the motion structure and the components, and will not cause the motion mechanism to become unadjusted or loose.

[0061] In conjunction with the first aspect, in certain implementations of the first aspect, the step of combining different digital fixtures, setting matching parameters according to the relative motion relationship, and obtaining matching digital fixtures with matching clearances further includes:

[0062] The paddle in the toggle module is assembled with the paddle shaft bracket in the main module, wherein the shaft holes at both ends of the paddle are rotated and assembled with the paddle shaft of the paddle shaft bracket, and the limiter in the toggle module is assembled horizontally in the housing in the main module;

[0063] Slidingly assemble the U-shaped groove of the shift fork in the shift button module and the swing rod of the main blade in the blade module;

[0064] The main rotating shaft on the main blade in the blade module is rotated and assembled with the mounting hole of the shell in the main body module, and the main rotating shaft of the auxiliary blade in the blade module is rotated and assembled with the mounting hole of the shell in the main body module.

[0065] According to the above technical means, different digital functional modules are assembled together to make the functions of the entire motion sample digital model complete.

[0066] In conjunction with the first aspect, in certain implementations of the first aspect, the clearance between the two end shaft holes of the paddle and the paddle shaft of the paddle shaft bracket at the assembly site is 0.25 to 0.4 mm, and the clearance between the stopper in the toggle module and the housing in the main module at the assembly site is 0.3 to 0.5 mm.

[0067] The single-side distance of the fitting clearance between the U-shaped groove of the shift fork in the button module and the swing rod of the main blade in the blade module is 1 to 2 mm;

[0068] The single-sided distance of the fitting clearance between the main rotating shaft on the main blade in the blade module and the mounting hole of the shell in the main module is 0.3~0.5mm, and the single-sided distance of the fitting clearance between the main rotating shaft of the auxiliary blade in the blade module and the mounting hole of the shell in the main module is 0.3~0.5mm.

[0069] According to the above technical means, the use of the above gaps between the digital functional modules can ensure the smoothness of the movement process of the motion structure and the components, and will not cause the motion mechanism to become unadjusted or loose.

[0070] In the second aspect, the present invention also proposes an integrated molding device for a vehicle motion sample, comprising a controller and a 3D printer.

[0071] In a third aspect, the present invention further proposes an air-conditioning window structure, comprising: manufacturing using the manufacturing method for integrally molding a vehicle motion sample as described above.

[0072] The beneficial effects of the manufacturing method, equipment, and air-conditioning window structure for integrally forming a vehicle motion sample provided by the present invention are at least as follows: the various components of the vehicle motion sample are designed and combined, and the functional motion sample is directly manufactured in one piece using a 3D printing process, replacing the traditional manufacturing process method of using mold casting, 3D printing, CNC machining, and other different processes for separate manufacturing and assembly, thereby reducing the process steps for manufacturing the motion sample and eliminating the assembly link of the motion sample. Therefore, the manufacturing method for integrally forming a vehicle motion sample of the present application directly eliminates the difficult, time-consuming, and labor-intensive assembly link, reduces the number of processes, reduces the manpower and equipment investment, and significantly shortens the manufacturing cycle of the vehicle motion sample.

DETAILED DESCRIPTION

[0085] The following will describe the embodiments of the present application with reference to the accompanying drawings and preferred embodiments. Those skilled in the art can easily understand the other advantages and effects of the present application from the contents disclosed in this specification. The present application can also be implemented or applied through other different specific embodiments, and the details in this specification can also be modified or changed in various ways based on different viewpoints and applications without departing from the spirit of the present application. It should be understood that the preferred embodiments are only for the purpose of illustrating the present application and are not intended to limit the scope of protection of the present application.

[0086] like Figure 11As shown, to facilitate the description of the solution of the present application, the manufacturing process of an automobile air-conditioning vent window with a complex and precise structure including sliding, rotating and other motion structures is taken as an example. The components of the original automobile air-conditioning vent window 1 generally include: an original decorative cover plate 11, an original dial button 12, an original dial plate 13, an original dial plate rotating shaft 14, an original dial plate rotating shaft bracket 15, an original limiter 16, an original shift fork 17, an original main blade 18, an original auxiliary blade 19, an original blade linkage rod 110, and an original housing 111. The linkage of the automobile air-conditioning vent window is that the original dial button 12 moves laterally on the original dial plate 13, driving the original shift fork 17 to move laterally, the original shift fork 17 moves laterally, the original main blade 18 rotates when the original main blade 18 rotates, the original blade linkage rod 110 moves when the original main blade 18 rotates, and the original blade linkage rod 110 drives the original auxiliary blade 19 to rotate and has a limit function; the original dial button 12 and the original dial plate 13 can rotate directly.

[0087] Through the solution of this application, a new automobile air-conditioning window structure is designed by combining Figure 3 and Figure 4 ) and 3D printing one-piece molding method to manufacture the physical car air-conditioning window. It should be noted that the digital model structure of this application is the same as the physical structure produced, so when performing structural representation, the physical structure is used to represent the digital model structure.

[0088] Example 1

[0089] like Figure 1 、 Figure 2 As shown, this embodiment provides a method for manufacturing a vehicle sports sample integrally formed, comprising the steps of:

[0090] Step S100: Acquire digital part models of the moving sample, and combine the digital part models into different digital fixed parts.

[0091] In digital model design software such as CATIA, simulation analysis of the coordinated motion of the air conditioner window assembly is performed, and based on the relative motion relationships of the components of the air conditioner window assembly, the previously fixed assembly parts are combined into a digital fixed assembly.

[0092] For example, the parts of the existing automobile air-conditioning window are digitally designed to obtain digital part models. Some digital part models that do not produce relative motion relationships are combined to form an integral digital fixing part. The original paddle shaft 14 and the original paddle shaft bracket 15 are combined to form an existing digital fixing part, namely the paddle shaft bracket 23 (refer to Figure 11 and Figure 4 ).like Figure 3 、 Figure 4As shown, the new automobile air-conditioning window structure in this embodiment mainly includes: a decorative cover 21, a dial button 22, a dial shaft bracket 23, a shift fork 24, a dial 25, a limiter 26, a main blade 27, an auxiliary blade 28, a blade linkage rod 29, and a shell 210.

[0093] Step S150: Classify different digital fixing components according to their functions to form different digital functional modules, wherein a digital functional module contains multiple digital fixing components.

[0094] In the specific process, in order to facilitate the design, different functional modules are divided according to the fixed support function, lateral movement function and longitudinal movement function. In this way, different digital fixings can be classified, making the part design process more standardized. Different functional modules can be designed synchronously for collaborative work and finally assembled. This ensures the smoothness of the part design process and improves work efficiency.

[0095] When dividing the functional modules of the air outlet window structure of the automobile air conditioner, the different digital functional modules specifically include: button module, blade module and main body module. Figure 4 、 Figure 5 As shown, the multiple digital fixed parts in the dial button module include: a dial button 22, a fork 24, a paddle 25 and a limiter 26. Figure 4 、 Figure 6 As shown, the multiple digital fixed parts in the blade module include: main blade 27, auxiliary blade 28, and blade linkage rod 29. Figure 4 、 Figure 7 As shown, the main module includes multiple digital fixtures: a decorative cover plate 21, a paddle shaft bracket 23, and a housing 210. The paddle shaft bracket 23 is composed of a paddle shaft 231 and a shaft 271 frame. The paddle shaft 231 and shaft 271 frame are digital part models. When manufacturing the air conditioner air outlet frame structure, the digital part models are divided according to their functions, which clarifies the design logic, standardizes the design process, and improves the efficiency of the air conditioner air outlet frame structure design.

[0096] Step S200: different digital fixing parts are combined, and matching parameters are set according to the relative motion relationship to obtain matching digital fixing parts with matching clearances.

[0097] In the digital design software, each digital fixture can be created as a separate file. Therefore, different digital fixtures need to be combined to determine their relative positions and motion relationships. This prevents confusion between the digital fixtures, ensures the correct motion relationships between the printed objects, and maintains the stability of the manufactured air conditioner outlet frame structure.

[0098] First, determine the assembly relationship between the various digital fixtures within the digital function module:

[0099] like Figure 4 、 Figure 5 As shown, in the dial button module, the dial button 22 and the paddle 25 are assembled by transverse sliding, the shift fork 24 is assembled by rotation on the dial button 22 , and the limiter 26 is assembled by rotation on the paddle 25 .

[0100] like Figure 4 、 Figure 6 As shown, in the blade module, the rotating shaft 271 of the main blade 27 is rotatably assembled with the connecting hole 291 of the blade linkage rod 29, and the rotating shaft 271 of the auxiliary blade 28 is rotatably assembled with the connecting hole 291 of the blade linkage rod 29. A shoulder structure larger than the diameter of the connecting hole 291 of the blade linkage rod 29 is provided at the top of the rotating shaft 271 of the main blade 27 and the top of the rotating shaft 271 of the auxiliary blade 28; the shoulder structure is directly designed on the rotating shaft 271 to prevent the blade linkage rod 29 from falling out of the rotating shaft 271 of the blade, realizing the limiting function. At the same time, no additional assembly parts are required after the product is processed, saving assembly time and improving production efficiency.

[0101] like Figure 4 、 Figure 7 As shown, in the main module, the decorative cover plate 21, the paddle shaft bracket 23, and the housing 210 are fixedly assembled and combined into a single integral module. Since there is no movement mechanism between the decorative cover plate 21, the paddle shaft bracket 23, and the housing 210, the snap-fit ​​assembly structure between these components is simplified. Filler is added to the existing connection between the decorative cover plate 21, the paddle shaft bracket 23, and the housing 210 to increase the local solid area, and the decorative cover plate 21, the paddle shaft bracket 23, and the housing 210 are added and combined into a single entity. This eliminates the need for additional assembly of the three components after molding, simplifying the production process.

[0102] Secondly, the assembly relationship between each digital functional module:

[0103] like Figure 4 、 Figure 5 、 Figure 8 As shown in Figure (1), the paddle 25 in the dial button module is matched with the paddle shaft bracket 23 in the main body module, as shown in FIG. Figure 8 As shown in FIG. (2), the shaft holes 251 at both ends of the paddle 25 are rotatably assembled with the paddle shaft 231 of the paddle shaft bracket 23, as shown in FIG. Figure 8 As shown in Figure (3), the limiting member 26 in the dial button module is assembled in a horizontal movement in the housing 210 in the main body module.

[0104] like Figure 4 、 Figure 5 、 Figure 6 (1) Figure, Figure 9 (1) Figure, Figure 9 As shown in FIG. (2), the U-shaped groove 241 of the shift fork 24 in the button module and the swing rod 272 of the main blade 27 in the blade module are slidably assembled.

[0105] like Figure 4 、 Figure 6 (1) Figure, Figure 9 As shown in Figure (3), the main rotating shaft 273 on the main blade 27 in the blade module is rotated and assembled with the mounting hole 211 of the shell 210 in the main module, and the main rotating shaft 273 of the auxiliary blade 28 in the blade module is rotated and assembled with the mounting hole 211 of the shell 210 in the main module.

[0106] Therefore, different digital functional modules are assembled together to make the functions of the entire motion sample digital model complete.

[0107] In step S200, the fit parameters specifically refer to the fit clearance of the combined components of the motion structure. Therefore, the fit parameters are set according to the relative motion relationship to obtain a digital motion sample model with a fit clearance. Specifically, the steps include:

[0108] Step S210: Combine different digital fixing parts to obtain matching digital fixing parts.

[0109] Step S220 : Acquire the outer surface of the embedded component in the matching digital fixture, and offset the outer surface to obtain a cutting surface.

[0110] Step S230: Cutting the outer cover component of the matching digital fixing component by cutting the surface to form a matching gap between the matching digital fixing components.

[0111] In the specific process, there are generally two types of movable connections between the assembled digital functional modules: sliding connections and rotational connections. In both connection types, one digital fixture is mounted on the outside of another digital fixture. Therefore, the digital fixture located on the inside is the inner component, and the other digital fixture mounted on the outside of the inner component is the outer component.

[0112] Therefore, different cutting surface forms are adopted according to the active connection relationship of different digital functional modules. The details are as follows:

[0113] When the outer cover slides over the inner component, the outer surfaces of the inner component on opposite sides are extracted and offset by a single distance, resulting in cut surfaces on both sides of the inner component. When the outer cover rotates over the inner component, the outer circumferential surface of the inner component is extracted and offset by a single distance, resulting in a cut surface surrounding the outer side of the inner component. These two excision methods ensure that the single distance of the excision is uniform, thereby ensuring the structural stability of the excised structure.

[0114] In the above steps, a cutting surface is generated by offsetting the surface of the embedded component of the matching digital fixture, and the outer shell is cut using the cutting surface. In this way, the fitting clearance between the matching digital fixtures can not only meet the relative motion requirements, but also standardize the forming of the fitting clearance, making the forming design of the fitting clearance more efficient.

[0115] Combine the above steps and apply them to the car air conditioner vents:

[0116] like Figure 5 (1) Figure and Figure 5 As shown in Figure (3), the upper and lower outer surfaces of the pick 25 are extracted and offset, and the offset cutting surface is used to cut the button 22, so that a fitting gap is formed between the button 22 and the pick 25. The unilateral distance between the pick 25 and the button 22 is the offset amount, so the total fitting gap is twice the unilateral distance. This allows the button 22 to slide normally on the pick 25. Figure 5 (1) Figure and Figure 5 As shown in Figure (2), the diameter of the shaft of the fork 24 is set to φ≥2mm, the outer surface of the shaft of the fork 24 is extracted and offset, and the offset cutting surface is used to cut the button 22. The offset is also a single-side distance, so that the fork 24 can rotate normally on the button 22. Figure 5 (1) Figure and Figure 5 As shown in Figure (2), the matching clearance between the limiting member 26 and the paddle 25 is determined in the same way.

[0117] like Figure 6 (1) Figure and Figure 6 As shown in Figure (2), the diameters of the rotating shaft 271 of the main blade 27 and the rotating shaft 271 of the auxiliary blade 28 are both set to be ≥2mm. The outer surfaces of the rotating shaft 271 of the main blade 27 and the rotating shaft 271 of the auxiliary blade 28 are extracted and offset. The cutting surfaces formed after the offset are used to cut the blade linkage rod 29 respectively, so that a connecting hole 291 is formed on the blade linkage rod 29, and the main blade 27 and the auxiliary blade 28 can rotate normally on the blade linkage rod 29.

[0118] like Figure 8 (1) Figure, Figure 8As shown in Figure (2), the outer surface of the shaft 271 of the main paddle shaft bracket 23 is extracted and offset, and the paddle 25 is cut using the offset cutting surface so that the paddle 25 can rotate normally on the main paddle shaft bracket 23; Figure 8 As shown in Figure (3), the housing 210 is slotted so that the limiting member 26 can move horizontally on the housing 210.

[0119] like Figure 9 As shown in Figure (3), the outer surface of the main rotating shaft 273 of the main blade 27 is extracted and offset, and the shell 210 is cut using the offset cutting surface so that the main blade 27 can rotate normally on the shell 210; the fitting clearance between the auxiliary blade 28 and the shell 210 is determined in the same way.

[0120] In step S230, when the fit clearance is perpendicular to the slice plane, the fit clearance in the slice plane is minimum. Therefore, the fit clearance is determined based on the slice thickness, the equipment single layer compensation amount, and the equipment precision error, where: 2(T+C)+E≥G≥T+C+2E; T is the slice thickness, C is the equipment single layer compensation amount, E is the absolute value of the equipment precision error, and T≥E, G is the unilateral distance of the fit clearance. When the unilateral fit clearance G≥T+C+2E, the matching embedded components and the outer cover components are both at the limit error, then the actual gap ≥T+C, which allows the printing device to identify and manufacture (print out) the support of the motion fit clearance, so that the sample can be successfully printed and manufactured. Therefore, gap support can also be set in the fit clearance to ensure that the embedded components and the outer cover components can not only form a gap, but also set support to ensure that the matching embedded components and the outer cover components are structurally stable during the printing process, so that the overall structure can be printed smoothly.

[0121] When the unilateral clearance 2(T+C)+E ≥ G and the mating surfaces are within the limit error, the actual clearance is ≤ 2(T+C)-E, where 2(T+C)-E > T+C. This allows the equipment to identify and create support for the kinematic clearance, allowing the prototype to be successfully printed and manufactured. Furthermore, the unilateral clearance is not excessively large, ensuring that the mating inner and outer components maintain a relatively stable fit after the actual product is manufactured, preventing them from being too loose.

[0122] In addition, in order to facilitate the dissolution of the support in the fitting gap formed by the embedded component and the outer cover component, a chamfer is provided at the opening of the fitting gap. For example, a 45° chamfer is provided at the opening of the connecting hole 291 formed on the blade linkage rod 29. In the process of dissolving the support, the solution quickly enters the fitting gap through the chamfer, and a single-sided fitting gap of 2(T+C)+E≥G is adopted. Even when the gap is not large, the solution can quickly enter and dissolve the support.

[0123] For support within the gap, since the gap is designed to be small, point supports are used, which is more conducive to 3D printing. To ensure better structural support and subsequent dissolution, the point supports are distributed along the extension direction of the embedded components. For example, the axis 271 of the main blade 27 and the axis 271 of the auxiliary blade 28 are distributed along the axial direction. Along the distribution direction, the point supports are distributed more sparsely toward the opening of the gap, while the point supports are distributed more densely toward the opening of the gap. For example, if both ends of the shaft are opened, the point supports near the ends of the shaft will become increasingly sparse, while the point supports near the center of the shaft will become increasingly dense. This dense point support provides stable support between the shaft 271 and the connecting hole 291, making the printed structure more stable and less prone to collapse and other dimensional deformation. The point supports with relatively sparse openings avoid excessive obstruction of the solution by the supports, thereby accelerating the entry of the solution into the gap and improving manufacturing efficiency.

[0124] By using the aforementioned single-sided clearance distance for the cut surface offset, the clearance created between the matching digital fixtures prevents interference with their motion, thereby maintaining a stable kinematic relationship between the various physical components of the manufactured motion prototype and improving the structural stability of the entire motion prototype. Furthermore, limiting the upper limit of the clearance ensures the structural strength of the outer cover component removed from the matching digital fixture.

[0125] Combine the above steps and apply them to the car air conditioner vents:

[0126] The unilateral distance between the paddle 25 and the toggle button 22 is 0.15 to 0.3 mm, the unilateral distance between the fork 24 and the toggle button 22 is 0.25 to 0.4 mm, and the unilateral distance between the stopper 26 and the paddle 25 is 0.25 to 0.4 mm. The unilateral distance between the rotating shaft 271 of the main blade 27 and the connecting hole 291 of the blade linkage rod 29 is 0.25 to 0.4 mm, and the unilateral distance between the rotating shaft 271 of the auxiliary blade 28 and the connecting hole 291 of the blade linkage rod 29 is 0.25 to 0.4 mm. The use of the above-mentioned clearances ensures the smooth movement of the motion structure and the assembly, preventing the motion mechanism from becoming misaligned or loose.

[0127] The clearance between the two end axial holes 251 of the paddle 25 and the paddle shaft 231 of the paddle shaft bracket 23 is 0.25 to 0.4 mm per side. The clearance between the stopper 26 in the toggle module and the housing 210 in the main module is 0.3 to 0.5 mm per side. The clearance between the U-shaped groove 241 of the toggle fork 24 in the toggle module and the swing lever 272 of the main blade 27 in the blade module is 1 to 2 mm per side. The clearance between the main shaft 273 of the main blade 27 in the blade module and the mounting hole 211 in the housing 210 in the main module is 0.3 to 0.5 mm per side. The clearance between the main shaft 273 of the auxiliary blade 28 in the blade module and the mounting hole 211 in the housing 210 in the main module is 0.3 to 0.5 mm per side. The use of the above-mentioned gaps between the digital functional modules can ensure the smoothness of the movement process of the motion structure and the components, and will not cause the motion mechanism to become unadjusted or loose.

[0128] Step S300: Setting a digital support member on the digital fixing member, connecting the matching digital fixing member through the digital support member, and obtaining a digital model of an integral motion sample.

[0129] In the specific process, after placing the matching digital fixings with matching clearances on the car air-conditioning outlet window in the appropriate position in the design window, the digital support parts are designed to ensure that the supports between the digital fixings with relative motion relationships can be removed under the premise that the entity can be 3D printed.

[0130] like Figure 10 As shown, the digitizing support member 30 in this embodiment includes a mesh base 31 and a top protrusion 32. The mesh base 31 decreases in thickness along its height in a stepwise manner. The mesh base 31 provides stable support, while the top protrusion 32 provides fixation. While achieving support, it also minimizes the structural impact on the connected digitizing fixture.

[0131] In this embodiment, the mesh base's perimeter indents 5mm for every 50mm increase in height. The digital support gradually decreases in thickness as its height increases, ultimately shrinking to a 3mm-tall top bump, which connects to and supports the digital fixture. This provides a more stable support structure, providing stable support for the connected digital fixture and preventing structural collapse and dimensional deformation during 3D printing.

[0132] like Figure 10 As shown, the supporting side length of the bottom of the mesh base is The unit is mm. H is the distance from the support point of the digital support and the digital fixing part to the printing plane. Rounded upward. With this support side length, as the height of the digital support increases, the support side length shortens, facilitating stable support at the top bump. Furthermore, during the post-3D printing soaking process to dissolve the support, this facilitates rapid fusing of the support from the upper end of the mesh base, allowing the actual moving part to quickly detach from the support, improving the efficiency of the dissolution process and further enhancing production and processing efficiency.

[0133] In addition, the support side length and height of the top layer of the mesh base are limited. The support side of the top layer of the mesh base is 5mm. The support height of the top layer of the mesh base is: when the remainder of H / 50 is greater than 3, then When the remainder of H / 50 is less than or equal to 3, H 顶 =50+remainder-3; where, To round down, set the top bump on the top layer of the mesh base.

[0134] The top layer of the mesh base of this structure cooperates with the top bumps, so that the top layer of the mesh base can stably support the top bumps. At the same time, a step is generated at the junction of the top bumps and the top layer of the mesh base. The bottom surface of the step is the top surface of the top layer of the mesh base, and the side surface of the step is the side surface of the entire top bump. Therefore, the top of the top bump supports the printed workpiece. By limiting the support height and support edge of the top layer of the mesh base, it is ensured that when the support edge of the top layer of the mesh base is 5mm, the support height formed can ensure the support strength of the entire mesh base, and the top bumps can provide stable support for the printed workpiece. In addition, the gaps between the generated steps facilitate the dissolving liquid to enter the gap between the top layer of the mesh base and the printed workpiece, thereby achieving rapid dissolution of the top bumps, thereby accelerating the dissolution rate of the top bumps and achieving the purpose of stable support and easy dissolution.

[0135] The digital model of the integral motion sample of the automobile air-conditioning window after adding digital support parts is sliced, and the sliced ​​data is imported into the 3D printer equipment for 3D printing manufacturing.

[0136] Step S400: 3D print the digital model of the integral motion sample to obtain a physical object of the integral motion sample, soak the physical object of the integral motion sample to dissolve the support part to obtain the motion sample, wherein the support part is obtained by 3D printing a digital support part.

[0137] The process involves importing sliced ​​data from the digital model of the integrated motion prototype into an FDM-3D printer. After setting process parameters such as print speed and print head temperature, production of the automotive air conditioner window display begins. The 3D printer uses a dual-nozzle printing system to simultaneously print both the support material and the motion prototype material. The support material is a soluble material. This simultaneous printing process allows the digital support and the digital fixture to be formed from different materials, facilitating the dissolution and removal of the printed support material.

[0138] The completed automotive air conditioner window vent is removed from the FDM 3D printer and thoroughly soaked in a sodium hydroxide solution or water solution to dissolve the 3D printed support components. After removing the support components, the vent is dried and the knob, fork, paddle, main blade, and auxiliary blade motion structures are functionally tested. This results in a fully functional automotive air conditioner window vent.
