Description

Technical Field

[0001] This invention belongs to the technical field of spray painting teaching equipment, specifically relating to an automotive spray painting training platform. Background Technology

[0002] Painting automotive body panels is an important part of car detailing and repair. For example, after bodywork repairs, body panels need to be painted; similarly, some car owners choose to paint designs on body panels to enhance the car's appearance. Painting requires a high level of skill from operators, necessitating extensive training before practical application. However, current training methods mostly use real paint, such as the car door panel painting training rack disclosed in existing technology CN117995037A. This approach has two drawbacks: firstly, the training cost is high; secondly, paint contains various harmful substances, increasing the risk of health hazards to operators during prolonged painting training. Therefore, improving the safety of paint painting training is a technical problem that needs to be addressed. Summary of the Invention

[0003] The purpose of this invention is to provide an automotive painting training platform that can improve the safety of paint painting training.

[0004] To achieve the above-mentioned objectives, the technical solution adopted by this invention is as follows: This application provides an automotive painting training platform, including a base, a fixing component, and a simulation component. The fixing component is used to fix the model parts. The simulation component is arranged opposite to the fixing component along a first direction. The simulation component includes a movable base, two rollers, and a water-reactive color-developing film. The movable base is movably connected to the base along the first direction. The two rollers are rotatably connected to the movable base, and the two rollers are spaced apart along a second direction, which is perpendicular to the first direction. The two ends of the water-reactive color-developing film are respectively wound around the two rollers.

[0005] In some embodiments, the water-reactive color-developing film includes a base color layer, a protective layer, and a water-reactive transparent layer stacked sequentially.

[0006] In some embodiments, the simulation component further includes a membrane support member, which includes two support portions and an elastic membrane body. The two support portions are rotatably connected to the movable seat on the same axis. The two support portions form a bent structure. The elastic membrane body is connected to the two support portions. The two support portions and the elastic membrane body form a triangular channel. The water-reactive color-developing membrane passes through the triangular channel.

[0007] In some embodiments, two membrane support members are provided, and the two membrane support members are spaced apart along the second direction.

[0008] In some embodiments, the two support portions are respectively provided with reaction portions, which are respectively provided on the outer bending side of the two support portions. The simulation component also includes a limiting component, which is provided between the two reaction portions.

[0009] In some embodiments, the limiting component includes a fixed cylinder, a movable cylinder, a flexible cover, and an elastic element. The fixed cylinder is connected to the movable seat and has an opening. The movable cylinder is sleeved on the fixed cylinder, and the fixed cylinder and the movable cylinder form a space with a variable volume. The movable cylinder is located on the inner curved side of the two support portions. The flexible cover covers the opening and is located between the two reaction portions. The elastic element connects the fixed cylinder and the movable cylinder.

[0010] In some embodiments, the limiting component further includes an extension portion connected to the movable cylinder.

[0011] In some embodiments, the two support parts are rotatably connected by a pivot, and the fixed cylinder is connected to the pivot.

[0012] In some embodiments, the fixing component includes two limiting plates, which are spaced apart along a first direction.

[0013] In some embodiments, the limiting plate is provided with a groove extending along a second direction, and the fixing assembly further includes a sliding part, a lifting part, and a force-applying part. The sliding part is slidably connected to the groove. The lifting part is movably connected to the sliding part along a third direction, and the first direction, the second direction, and the third direction are perpendicular to each other. The force-applying part is movably connected to the lifting part along the first direction.

[0014] The present invention has the following beneficial effects: 1. Once the water-reactive color-developing film is taut, lock the two reels, then move the moving base so that the film covers the surface of the model part. At this point, trainees can use a spray gun for painting practice or a drawing tool for painting practice. The use of the model part improves the simulation accuracy of the training. After each training session, separate the water-reactive color-developing film and the model part. One reel winds up the water-reactive color-developing film after it has been moistened, while the other reel unwinds it. The next training session can then begin, improving training efficiency.

[0015] 2. By spraying water onto the water-reactive color-developing film to simulate the process of painting, the film can be reused after drying, reducing training costs. Furthermore, water is a harmless material, reducing the risk of harm to trainees. Attached Figure Description

Detailed Implementation

[0018] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Unless otherwise specified, the technical means used in the embodiments are conventional means well known to those skilled in the art.

[0019] In the description of this invention, it should be understood that the terms "longitudinal", "lateral", "up", "down", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this invention, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this invention.

[0020] See Figure 1 , Figure 2 and Figure 4This application provides an automotive painting training platform, including a base 1, a fixing component 4, and a simulation component 2. The fixing component 4 is used to fix the model part 3. The simulation component 2 is arranged opposite to the fixing component 4 along a first direction. The simulation component 2 includes a movable base 26, two rollers 22, and a water-reactive color-developing film 21. The movable base 26 is movably connected to the base 1 along the first direction. The two rollers 22 are rotatably connected to the movable base 26 respectively. The two rollers 22 are spaced apart along a second direction, which is perpendicular to the first direction. The two ends of the water-reactive color-developing film 21 are respectively wound around the two rollers 22.

[0021] Model part 3 refers to a component of the vehicle, such as the vehicle's body panels or the door structure.

[0022] The simulation component 2 and the fixed component 4 are arranged opposite each other along the first direction, so that the simulation component 2 can be close to or far away from the fixed component 4.

[0023] The first direction could be Figure 1 The direction shown by the X-axis, the second direction can be Figure 1 The direction indicated by the Y-axis.

[0024] The specific structure by which the movable base 26 and the base 1 are movably connected can be selected from existing structures. For example, the base 1 can be provided with a guide rail, and the movable base 26 can be slidably connected to the guide rail. Furthermore, the base 1 can be provided with a locking component for locking or unlocking the movable base 26.

[0025] The movable base 26 may include a movable part 24 and a rotating part 25. The movable part 24 is movably connected to the base 1, and the rotating part 25 is rotatably connected to the movable part 24. The rotation axis of the rotating part 25 extends along a second direction. A scroll 22 may be disposed on the rotating part 25, allowing the scroll 22 to rotate relative to the movable part 24. This, in turn, allows the water-reactive color-developing film 21 disposed on the scroll 22 to also rotate relative to the movable part 24, enabling the water-reactive color-developing film 21 to better cover the model part 3. Similarly, the movable part 24 may also be provided with a locking component for locking or unlocking the rotating part 25. The locking components of the base 1 and the movable part 24 can be selected from existing technologies, and their structures and working principles are well known to those skilled in the art and will not be described in detail here.

[0026] One of the two spools 22 is used to wind up the water-reactive color-developing film 21, and the other is used to unwind the water-reactive color-developing film 21, so that the water-reactive color-developing film 21 can be taut and the part of the water-reactive color-developing film 21 facing the model part 3 can be switched.

[0027] The water-reactive color-developing film 21 is a coating structure that can display color or pattern when exposed to water. Its specific materials and color-developing principle are known to those skilled in the art. In general, the surface of the water-reactive color-developing film 21 is provided with a color-changing ink layer. For example, the color-changing ink layer can be the color-changing ink layer disclosed in the prior art CN102862406A. When the color-changing ink layer comes into contact with water, the color-changing ink layer becomes transparent, so that the color or pattern of the water-reactive color-developing film 21 can be displayed. When the color-changing ink layer dries, it will turn back to white.

[0028] By spraying water onto the water-reactive color-developing film 21 to simulate the process of painting, the film can be reused after drying, reducing training costs. Furthermore, water is a harmless material, reducing the risk of harm to trainees.

[0029] Once the water-reactive color-developing film 21 is taut, the two reels 22 are locked, and then the moving base 26 is moved so that the water-reactive color-developing film 21 can cover the surface of the model part 3. At this time, the trainee can use a spray gun for spray painting training or use a drawing tool for painting training. The model part 3 improves the simulation of the training. After one training session, the water-reactive color-developing film 21 and the model part 3 are separated. One reel 22 rolls up the water-reactive color-developing film 21 after it has been wetted, and the other reel 22 unrolls the water-reactive color-developing film 21. Then the next training session can begin, which improves the training efficiency.

[0030] See Figure 3 In some embodiments, the water-reactive color-developing film 21 includes a base color layer 213, a protective layer 212, and a water-reactive transparent layer 211 stacked sequentially.

[0031] The water-sensitive transparent layer 211 is the color-changing ink layer.

[0032] When the water-sensitive transparent layer 211 comes into contact with water, it becomes transparent, allowing the color of the base color layer 213 to be displayed, thus simulating the process of spraying or painting.

[0033] The protective layer 212 can be a transparent plastic layer. The protective layer 212 can protect the base color layer 213 and reduce the risk of the base color layer 213 being soaked after the water-sensitive transparent layer 211 is permeated. The protective layer 212 can be disposed on both sides of the base color layer 213 in the thickness direction.

[0034] See Figure 1 and Figure 5In some embodiments, the simulation component 2 further includes a membrane support component 23, which includes two support portions 231 and an elastic membrane 232. The two support portions 231 are rotatably connected to the movable seat 26 on the same axis. The two support portions 231 form a bent structure. The elastic membrane 232 is connected to the two support portions 231. The two support portions 231 and the elastic membrane 232 form a triangular channel. The water-reactive color-developing membrane 21 passes through the triangular channel.

[0035] The elastic membrane 232 is a material capable of producing elastic deformation.

[0036] A spring or torsion spring can be provided between the two support parts 231, so that the two support parts 231 tend to separate from each other.

[0037] The two support parts 231 and the elastic membrane 232 form an isosceles triangular structure, with the elastic membrane 232 facing the water-sensitive color-developing membrane 21.

[0038] The base is provided with abutment parts corresponding to the two support parts 231.

[0039] The triangular channel is used for the water-reactive color-developing membrane 21 to pass through, so that the membrane support component 23 can guide the water-reactive color-developing membrane 21.

[0040] The portion where the elastic membrane 232 and the support portion 231 are connected is used for inserting the water-reactive color-developing membrane 21, so that the elastic membrane 232 and the support portion 231 can work together to stretch the water-reactive color-developing membrane 21.

[0041] One end of the support 231 is rotatably connected to the movable seat 26 as the connecting end, and the other end is the movable end. The elastic membrane 232 is connected to the movable ends of the two support 231s. When the movable seat 26 moves toward the model part 3, the two support 231s abut against the abutting part. Under the action of the abutting part, the two movable ends tend to separate from each other. At the same time, the included angle between the elastic membrane 232 and the support 231 gradually decreases. This allows the water-reactive color membrane 21 to be fully stretched as the two movable ends separate, thus allowing the water-reactive color membrane 21 to flatly adhere to the surface of the model part 3, increasing the simulation level of the training. On the other hand, as the angle between the elastic membrane 232 and the support 231 gradually decreases, the clamping area of ​​the elastic membrane 232 and the support 231 on the water-reactive color-developing membrane 21 can adaptively and gradually increase, ensuring the clamping effect on the water-reactive color-developing membrane 21 and reducing the risk of the water-reactive color-developing membrane 21 falling off between the elastic membrane 232 and the support 231 when it is opened. Furthermore, the coordinated clamping of the water-reactive color-developing membrane 21 by the elastic membrane 232 and the support 231 reduces the risk of damage to the water-reactive color-developing membrane 21. Moreover, moving the movable seat 26 closer to the model part 3 allows for quick and simultaneous clamping of both sides of the water-reactive color-developing membrane 21. Conversely, moving the movable seat 26 away from the model part 3 allows the membrane support component 23 to unlock its clamping of the water-reactive color-developing membrane 21, resulting in high efficiency and speed.

[0042] The abutment can be movably connected to the base 1 along the first direction, so that the distance between the abutment and the support 231 can be adjusted.

[0043] See Figure 1 In some embodiments, two membrane support members 23 are provided, and the two membrane support members 23 are spaced apart along the second direction.

[0044] Along the second direction, the model part 3 can be positioned between the two membrane support parts 23.

[0045] By setting two membrane support components 23, the water-reactive color-developing membrane 21 can be stretched on both sides of the model part 3.

[0046] See Figure 6 In some embodiments, the two support portions 231 are respectively provided with reaction portions 233, and the two reaction portions 233 are respectively provided on the outer bending side of the two support portions 231. The simulation component 2 also includes a limiting component 234, which is provided between the two reaction portions 233.

[0047] The inner curved side of the support 231 refers to the two sides of the support 231 that are close to each other after the two support parts 231 are bent, and the outer curved side of the support 231 refers to the side opposite to the inner curved side.

[0048] When the movable end of the support 231 separates, the included angle between the two reaction parts 233 gradually decreases. By setting the limiting member 234 between the two reaction parts 233, the limiting member 234 can limit the travel of the movable end, reducing the risk of damage to the water-reactive color-developing film 21 due to excessive force applied by the film support member 23.

[0049] See Figure 7 In some embodiments, the limiting component 234 includes a fixed cylinder 236, a movable cylinder 238, a flexible cover 235, and an elastic element 237. The fixed cylinder 236 is connected to the movable seat 26 and has an opening. The movable cylinder 238 is fitted onto the fixed cylinder 236, and the fixed cylinder 236 and the movable cylinder 238 form a variable-volume space. The movable cylinder 238 is located on the inner curved side of the two support portions 231. The flexible cover 235 covers the opening and is located between the two reaction portions 233. The elastic element 237 is connected to the fixed cylinder 236 and the movable cylinder 238.

[0050] In an embodiment where two membrane support members 23 are provided, a limiting member 234 is provided on opposite sides of the two membrane support members 23.

[0051] The movable cylinder 238 is fitted onto the fixed cylinder 236, allowing the movable cylinder 238 to move relative to the fixed cylinder 236. When the movable cylinder 238 moves, the volume of the space enclosed by the movable cylinder 238 and the fixed cylinder 236 can change.

[0052] The flexible cover 235 covers the opening, so that the movable cylinder 238 can be moved by the flexible cover 235. That is, when the flexible cover 235 is compressed, the gas in the flexible cover 235 enters the fixed cylinder 236, thereby pushing the movable cylinder 238 to move.

[0053] The elastic element 237 is used to reset the movable cylinder 238. That is, when the external force on the flexible cover 235 disappears, the elastic element resets the movable cylinder 238, thereby allowing the flexible cover 235 to re-expand. The elastic element 237 is also used to limit the travel of the movable cylinder 238 away from the fixed cylinder 236, thereby preventing the flexible cover 235 from being completely compressed, and allowing the flexible cover 235 to limit the support portion 231.

[0054] The elastic element 237 can be a spring.

[0055] The movable cylinder 238 is located on the inner curved side of the two support parts 231, so that the movable cylinder 238 can be used to apply pressure to the water-sensitive color layer.

[0056] A flexible cover 235 is positioned between the two reaction parts 233, allowing it to limit the movement of the two support parts 231. While the water-reactive color-developing film 21 can be stretched open by the film-supporting component 23 near the two rollers 22, the tautness of the film decreases as it approaches the center between the rollers 22. In this embodiment, by appropriately adjusting the size of the flexible cover 235, pressure can be applied to the center of the film after it is stretched just below the rollers 22 via the movable cylinder 238. This ensures the film fits snugly against the model part 3, improving the simulation accuracy of the training.

[0057] See Figure 6 and Figure 7 In some embodiments, the limiting component 234 further includes an extension portion 239, which is connected to the movable cylinder 238.

[0058] The extension section 239 can increase the contact area between the movable cylinder 238 and the water-reactive color-developing film 21, thereby improving the straightening effect on the water-reactive color-developing film 21.

[0059] See Figure 5 and Figure 6 In some embodiments, the two support parts 231 are rotatably connected by a pivot, and the fixed cylinder 236 is connected to the pivot.

[0060] When the support part 231 rotates, the shaft remains stationary.

[0061] The fixed cylinder 236 is connected to the rotating shaft, which allows the movable cylinder 238 to move as far away from the water-reactive color-developing film 21 as possible when the support 231 is not in contact with the abutment, reducing the risk of obstructing the movement of the water-reactive color-developing film 21. When the support 231 contacts the abutment, the fixed cylinder 236 can first drive the movable cylinder 238 to move towards the water-reactive color-developing film 21, reducing the stroke that the movable cylinder 238 needs to be driven by the flexible cover 235. This allows the flexible cover 235 to be set smaller, and the movable end of the support 231 to be separated as much as possible, increasing the spreading effect on both sides of the water-reactive color-developing film 21.

[0062] See Figure 2 In some embodiments, the fixing component 4 includes two limiting plates 41, which are spaced apart along a first direction.

[0063] The two limiting plates 41 can form a track structure, and the model part 3 can be placed between the two limiting plates 41 first, so as to facilitate the movement of the model part 3.

[0064] See Figure 2In some embodiments, the limiting plate 41 is provided with a groove 42 extending along a second direction, and the fixing assembly 4 further includes a sliding part 43, a lifting part 44, and a force-applying part 45. The sliding part 43 is slidably connected to the groove 42. The lifting part 44 is movably connected to the sliding part 43 along a third direction, and the first direction, the second direction, and the third direction are perpendicular to each other. The force-applying part 45 is movably connected to the lifting part 44 along the first direction.

[0065] Each limit plate 41 may be provided with multiple sliding parts 43, lifting parts 44 and force-applying parts 45.

[0066] The sliding part 43 is slidably connected to the slide groove 42, allowing the sliding part 43 to move relative to the limiting plate 41, thereby facilitating the adjustment of the position of the fixed model part 3. The sliding part 43 may be provided with a locking component to lock or unlock the sliding part 43. For example, the locking component here may be a bolt. The bolt is provided on the sliding part 43. Tightening the bolt causes it to abut against the limiting plate 41, and the sliding part 43 is locked. Conversely, loosening the bolt causes it to no longer abut against the limiting plate 41, and the sliding part 43 is unlocked.

[0067] The third direction could be Figure 1 The directions indicated by the Z-axis are: the first and second directions can be parallel to the horizontal plane, and the third direction can be parallel to the vertical plane.

[0068] For example, the sliding part 43 is provided with a sliding hole, and the lifting part 44 is inserted into the sliding hole, allowing the lifting part 44 to move in a third direction. The sliding part 43 may be provided with a bolt, which abuts against the lifting part 44 to lock the lifting part 44. Conversely, loosening the bolt so that it no longer abuts against the lifting part 44 will unlock the lifting part 44. The force-applying part 45 can be threadedly connected to the lifting part 44, so that by rotating the force-applying part 45, the force-applying part 45 can move in the first direction.

[0069] The force-applying parts 45 of the two limiting plates 41 are arranged opposite each other.

[0070] By adjusting the position of the lifting part 44 relative to the sliding part 43, and then adjusting the position of the force-applying part 45, the multiple force-applying parts 45 cooperate to clamp the model part 3, thereby fixing the model part 3 to the base.

[0071] The above embodiments are merely descriptions of preferred embodiments of the present invention and are not intended to limit the scope of the present invention. Any modifications, alterations, alterations, or substitutions made by those skilled in the art to the technical solutions of the present invention without departing from the spirit of the present invention should fall within the protection scope defined by the claims of the present invention.
