Abstract
Description
Technical Field
[0001] This utility model relates to the field of prototype models, and in particular to a prototype model anti-collision device. Background Technology
[0002] Prototypes are physical prototypes used in the product development stage to verify design concepts, perform functional tests, or demonstrate effects. They are mainly made of materials such as plastic, metal, and resin through processes such as CNC machining, 3D printing, and silicone molding. They can accurately represent the product's appearance details and structure. Currently, these prototypes are widely used in fields such as electronics, automobiles, and home furnishings to help optimize design defects and reduce mold opening risks. They are a key link in the new product development process, bridging design and mass production.
[0003] Currently, clients typically commission manufacturers to create prototype models to obtain three-dimensional models for verifying design concepts. These models are not mass-produced and are therefore scarce. For some prototype models requiring visual verification, the overall structure and components of the sample need to be statically displayed for observation by multiple parties. However, due to the lack of adequate external protection for traditional prototype display structures, the prototype may be damaged by accidental impacts during the display process. Since the structure is not yet finalized and mass production has not been possible, the scarcity of prototype models means that damage to them could potentially delay normal product development progress and ultimately cause various losses.
[0004] Therefore, it is necessary to provide a new anti-collision device for prototype models to solve the above-mentioned technical problems. Utility Model Content
[0005] The technical problem solved by this utility model is to provide a prototype model anti-collision device that can provide good external protection for prototype models, thereby enabling them to be safely displayed statically.
[0006] To solve the above-mentioned technical problems, the present invention provides a hand-made model anti-collision device comprising: a base, a protective structure I installed on the top of the base, a protective structure II installed on the rear wall surface of the base, and a guide structure provided at the bottom of the base; the protective structure I includes an upper fixed cover, a bottom support fixedly connected to the upper surface of the base, a front opening on the front wall surface of the upper fixed cover, a bottom surface of the upper fixed cover fixedly connected to the edge of the upper surface of the base, the bottom support located inside the upper fixed cover, a protective liner adhered to the inner wall of the upper fixed cover, and a front cover structure installed on the surface of the upper fixed cover;
[0007] The second protective structure includes two connectors arranged in a left-right configuration. The upper and lower ends of the two connectors are respectively fixedly connected to the base and the rear wall surface of the upper fixed cover. Spring shock absorbers are symmetrically fixedly connected to the rear wall surface of the connectors. Fixing structures are provided at the rear side of the spring shock absorbers on both the left and right sides. Each fixing structure includes a fixing member, which is fixedly connected to the two spring shock absorbers on the adjacent side.
[0008] As a further embodiment of this utility model, the two fixing members distributed on the left and right are fixedly connected by a connecting plate. Both the upper and lower ends of the fixing members are fixedly connected with ear plates, and the surface of the ear plates is provided with mounting holes.
[0009] With the above technical solution, when installing this structure, it is necessary to first open holes corresponding to the installation holes on the wall at a suitable location, and then use expansion bolts and expansion nuts to fix the ear plate to the wall.
[0010] As a further embodiment of this utility model, the guide structure includes a slider, two sliders are provided and distributed left and right, the two sliders are respectively fixedly connected to the left and right edges of the bottom of the base, a guide rail is slidably connected inside the slider, one end of the guide rail is fixedly connected to the surface of the fixing member on the adjacent side, and a reinforcing rib is fixedly connected between the guide rail and the fixing member.
[0011] Through the above technical solution, this device, in order to facilitate the display of the prototype model and its various components, is specially equipped with an upper fixed cover on the upper side of the base, and a frame is hinged to the front opening of the upper fixed cover. Users can view the interior through the observation window inside the frame. The base is equipped with a bottom support, and the inner wall of the upper fixed cover is equipped with a protective lining made of sponge. Therefore, when the structure is impacted, causing the prototype model and parts inside to shift or fall, the surrounding sponge structure can provide good cushioning protection, reducing the possibility of damage or scratches to the surface. Furthermore, the upper fixed part and the connecting part on the rear side of the base are connected to the fixed part through spring shock absorbers. When the front side is impacted, its kinetic energy can be absorbed by four sets of spring shock absorbers, thereby effectively reducing the impact on the upper fixed cover, base, and observation window, thus extending the service life of the structure and protecting the safety of the internal model. The structure is reasonably designed and easy to use.
[0012] As a further embodiment of this utility model, a frame is hinged to the front wall surface of the upper fixed cover located above the front opening, and an observation window is fixedly connected to the inner wall of the frame. Controllable gas springs are hinged between the left and right side wall surfaces of the frame and the side wall surface of the upper fixed cover on the adjacent side.
[0013] With the above technical solution, a controllable gas spring is hinged between the frame and the upper fixed cover. In this way, when the user lifts the frame, the frame can stop at any angle, meeting the user's multi-angle opening and closing needs.
[0014] As a further embodiment of this utility model, fasteners are fixedly connected to the left and right side walls of the frame, and movable hooks are fixedly connected to the rear wall of the upper fixed cover located behind the fasteners, and the movable hooks are engaged with the fasteners.
[0015] With the above technical solution, when the frame is closed, the user can fasten the movable hooks and buckles on both sides to form a locking buckle to fix the frame in place.
[0016] As a further embodiment of this utility model, the observation window is made of tempered glass, and the bottom support and protective lining are both made of sponge.
[0017] Through the above technical solutions, tempered glass is harder and more impact-resistant than traditional glass, effectively protecting the safety of the internal model. The bottom support and protective lining are made of sponge material, so when a fragile model is displayed inside, if the model is accidentally impacted and falls, the sponge can provide excellent cushioning and protection, reducing the possibility of damage.
[0018] Compared with related technologies, the anti-collision device for prototype models provided by this utility model has the following beneficial effects:
[0019] To facilitate the display of prototype models and their components, this device features a fixed cover on the upper side of the base. A frame is hinged to the front opening of the fixed cover, allowing users to view the interior through an observation window. The base has a bottom support, and the inner wall of the fixed cover is lined with a protective sponge. Therefore, when the structure is impacted, causing the prototype models and parts inside to shift or fall, the surrounding sponge structure provides excellent cushioning, reducing the possibility of surface damage or scratches. Furthermore, the upper fixing component and the connecting parts at the rear of the base are connected to the fixing component via spring shock absorbers. When an impact occurs at the front, the kinetic energy is absorbed by four sets of spring shock absorbers, effectively reducing the impact on the fixed cover, base, and observation window, thus extending the structure's lifespan and protecting the internal model. The structure is rationally designed and easy to use. Attached Figure Description

The prototype model anti-collision device includes:
[0028] The base 10 has a protective structure 1 installed on its top, a protective structure 2 3 installed on its rear wall surface, and a guide structure 6 provided at its bottom.

[0031] When installing this structure, holes corresponding to the mounting holes need to be drilled on the wall at a suitable location, and the ear plate 5 is fixed to the wall using a combination of expansion bolts and expansion nuts.
[0032] like Figure 1-4 As shown, the guide structure 6 includes two sliders 14, which are arranged in a left-right distribution. The two sliders 14 are fixedly connected to the left and right edges of the bottom of the base 10, respectively. The sliders 14 are slidably connected to the guide rails 7.

Therefore, when the structure is impacted, causing the prototype model and its components to shift or fall, the surrounding sponge structure provides excellent cushioning protection, reducing the possibility of surface damage or scratches. Furthermore, the upper fixed part 15 and the connecting part 13 on the rear side of the base 10 are connected to the fixed part 15 via spring shock absorbers 12. When an impact occurs on the front side, its kinetic energy can be absorbed by four sets of spring shock absorbers 12, effectively reducing the impact on the upper fixed cover 8, the base 10, and the observation window 16, thereby extending the service life of the structure and protecting the safety of the internal model. The structure is reasonably designed and easy to use.

[0038] like Figure 1-4 As shown, the observation window 16 is made of tempered glass, and the bottom support 19 and the protective liner 20 are both made of sponge.
[0039] Tempered glass is harder and more impact-resistant than traditional glass, effectively protecting the safety of the internal model. The bottom support 19 and the protective liner 20 are made of sponge material. When a fragile model is displayed inside, the sponge can provide excellent cushioning and protection if the model is accidentally impacted and falls, reducing the possibility of damage.

The base 10 has a bottom support 19, and the inner wall of the upper fixed cover 8 is lined with a protective lining made of sponge. Therefore, when the structure is impacted, causing the prototype model and its components to shift or fall, the surrounding sponge structure provides excellent cushioning protection, reducing the possibility of surface damage or scratches. Furthermore, the upper fixed part 15 and the connecting part 13 on the rear side of the base 10 are connected to the fixed part 15 via spring shock absorbers 12. When an impact occurs on the front side, its kinetic energy can be absorbed by four sets of spring shock absorbers 12, effectively reducing the impact on the upper fixed cover 8, the base 10, and the observation window 16, thereby extending the service life of the structure and protecting the safety of the internal model. The structure is reasonably designed and easy to use.
