Description

Technical Field

[0001] This utility model relates to the field of model technology, and in particular to a simulation heat dissipation structure for a train model. Background Technology

[0002] In the world of model trains, enthusiasts focus on the realism of the models, striving to make them identical to real trains. Real locomotives have cooling systems installed, so even if a model train doesn't require cooling, it will still mimic the cooling system of a real train.

[0003] For example, Chinese patent CN 105944382B discloses a train model that has a fan and cooling vents installed on the top of the rear carriage to simulate the cooling of a real train. Its drawback is that the blades on the cooling vents are installed with gaps that cannot be closed. Real trains, however, are designed with windows that can be opened and closed to protect them from rain. Therefore, the simulation accuracy of this model is somewhat lower, and dust and debris can fall into the train model through the gaps. Summary of the Invention

[0004] To address the technical problem that the heat dissipation windows on the roof of existing train models cannot be closed, this utility model provides an openable and closable roof heat dissipation structure.

[0005] The present invention adopts the following technical solution:

[0006] A heat dissipation structure for a train model includes blades 1 and a mounting frame. Each of the two main beams 21 on the left and right sides of the mounting frame has a row of circular holes 23. The blades have a rotating shaft 11 on their side, which is rotatably installed in the circular holes 23. The center-to-center distance of the circular holes 23 is smaller than the width of the blade.

[0007] The wall thickness of blade 1 is less than 0.2 mm.

[0008] The blade 1 and the shaft 11 are an integral thin plate structure. The blade 1, which is rectangular thin plate in shape, has a portion of its ends extending out to serve as the shaft 11.

[0009] Blade 1 and shaft 11 are formed by etching.

[0010] The rotating shaft 11 is installed in the bushing, and the bushing and the round hole 23 are fitted together. From the cross-section, the bushing is a structure with an outer circle and an inner square.

[0011] The height of the main beam 21 of the mounting frame gradually increases from both ends to the middle, and the height of the circular holes 23 on the main beam 21 gradually increases from both ends to the middle.

[0012] The two main beams 21 of the mounting frame are connected by three crossbeams 24, which are located on both sides and at the highest point in the middle of the main beams 21.

[0013] The mounting frame has extended mounting ribs 22 on its outer side.

[0014] The mounting frame is attached to the top of the train model, with a fan installed underneath.

[0015] The train model has two or more mounting frames on top.

[0016] This utility model has the following beneficial effects:

[0017] 1. The heat dissipation window is an openable structure. It is closed when not in use to prevent dust or other foreign objects from falling into the train model. When it needs to be opened, the blades rotate to open the window.

[0018] 2. The blades are designed to be thin enough that the fan below only needs a small amount of power to blow the blades.

[0019] 3. To reduce wear on the mounting holes, a bushing was designed to mount the blade shaft. Attached Figure Description

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0026] Example 1:

[0027] like Figure 1 The blade shown has a rotating shaft 11 on its side. The blade 1 and the rotating shaft 11 are a single thin plate structure. The blade 1, which is rectangular thin plate shaped, has a portion of its ends extending out to serve as the rotating shaft 11.

[0028] For the sake of lightness and thinness, the wall thickness of blade 1 and shaft 11 in this embodiment is 0.1mm, so that the fan can be driven by a small amount of wind. Conventional processing methods cannot produce such a thin structure, so blade 1 and shaft 11 are formed by etching.

[0029] like Figure 2 and Figure 3 As shown, the main beam 21 of the mounting frame gradually increases in height from both ends to the middle. The two main beams 21 of the mounting frame are connected by three crossbeams 24, located on both sides and at the highest point in the middle of the main beam 21. Each of the left and right main beams 21 of the mounting frame has a row of circular holes 23, with the height of the circular holes 23 gradually increasing from both ends to the middle. Blades 1 are installed one by one into the circular holes 23, with the rotating shaft 11 inserted into the holes 23. The edge of the lowest blade 1 rests on the lowest crossbeam 24, and the edges of subsequent blades 1 rest on the previous blade 1. Extending mounting ribs 22 extend from the outside of the mounting frame, which are used to fix the mounting frame to the top of the train model. In this embodiment, two mounting frames are arranged side-by-side to form a heat dissipation window. Below the heat dissipation window is a fan. When the fan is off, the blades 1 keep the heat dissipation window closed under gravity. Starting the fan blows the blades 1 open the heat dissipation window.

[0030] Example 2:

[0031] This embodiment adds a bushing structure to the basis of embodiment 1. The bushing is designed to reduce wear between the rotating shaft 11 and the round hole. Because the rotating shaft 11 is not a cylinder, the cross-section of the rotating shaft 11 formed by etching is square. The bushing is a structure with an outer circle and an inner square. The rotating shaft 11 is installed in the square hole in the center of the bushing, and the bushing and the round hole 23 are fitted together.
