Description

Technical Field

[0001] The utility model relates to the field of track models, in particular to the field of windshield structures of track models, and in particular to a track model close-connected simulation windshield. Background Art

[0002] With the continuous development of science and technology, the details of rail transit vehicle models are gradually consistent with real rail vehicles, that is, the real rail vehicles are reduced in size according to a certain ratio and made into rail transit vehicle models. However, due to the limitation of placement space, it is impossible to completely restore the use environment of rail vehicles. This requires the vehicle model to be able to achieve smaller diameter turns. When turning, the deflection gap between two adjacent carriages will increase as the turning diameter becomes smaller, which will either easily cause the windshields between the two adjacent carriages to separate, forming a larger gap, or easily cause the windshields between the two adjacent carriages to be squeezed and deformed toward the inner end of the turn, causing the vehicle or locomotive to derail. The former is not only unsightly, but also leads to poor simulation of the entire track model. The latter easily leads to squeezing and derailment between the windshields of the track model. In addition, some track models directly abandon the windshield or design the windshield to be non-contact. These methods will cause the simulation type of the track model to deteriorate. Based on this, the utility model proposes a track model close-contact simulation windshield. Utility Model Content

[0003] In order to solve the problem mentioned in the background above that the windshield between two adjacent carriages becomes larger due to the smaller turning diameter, resulting in a gap and low simulation degree or causing the windshield to be squeezed toward the inside of the turn and derailed, the utility model provides a track model close-fitting simulation windshield.

[0004] In order to achieve the above technical purpose, the technical solution adopted by the utility model is as follows.

[0005] A track model close-fitting simulation windshield, comprising a fixed frame door, a connecting frame and an elastic sheet arranged at the end of a carriage or a locomotive, the connecting frame is located on the side of the fixed frame door facing the outside, the fixed frame door is fixedly arranged at the end of the carriage or the locomotive, a connecting buckle is arranged on the side of the connecting frame facing the fixed frame door, a hook is arranged at the end of the connecting buckle, and the hook passes through an avoidance notch arranged on the fixed frame door and hooks the fixed frame door, the connecting buckle is restricted by the avoidance notch to move in the vertical direction, and the connecting buckle can swing in the horizontal direction;

[0006] The elastic sheet is located on the side of the fixed frame door facing the interior of the carriage or locomotive. Initially, the hook hooks the fixed frame door and the elastic sheet contacts the hook.

[0007] A windshield is arranged on the side of the connection frame facing the outside, the windshields on two adjacent carriages are in contact with each other, and the windshields on the locomotive coupling are in contact with each other.

[0008] As further improvement and optimization of the utility model.

[0009] There are two groups of connecting buckles which are respectively located on the upper and lower sides of the connecting frame.

[0010] As further improvement and optimization of the utility model.

[0011] The elastic sheet is made of an elastic metal sheet.

[0012] As further improvement and optimization of the utility model.

[0013] The windshield is a metal windshield, a rubber windshield, or a folding windshield.

[0014] As further improvement and optimization of the utility model.

[0015] A protrusion extends from one side of the fixed frame door toward the interior of the carriage, and the side of the protrusion facing the interior of the carriage or the locomotive coupling is composed of a middle plane and a side inclined surface. Two side inclined surfaces are provided and are respectively located on both sides of the middle plane along the extension direction of the carriage, and the distance between the two side inclined surfaces decreases along the extension direction of the carriage and in the direction from the connecting frame to the fixed frame door. The hook of the connecting buckle contacts the protrusion, and initially, the hook contacts the middle plane of the protrusion;

[0016] There are two protrusions corresponding to the connecting buckles, and the two protrusions are respectively located on the upper and lower sides of the fixed frame door.

[0017] As further improvement and optimization of the utility model.

[0018] The elastic piece is in the shape of a Chinese character "Yu" or a rectangle.

[0019] Compared with the prior art, the utility model has the following beneficial effects:

[0020] 1. In this solution, when moving in a straight line, the windshields on two adjacent carriages or locomotives are in contact with each other under the outward force of the elastic sheet, and no gap is formed, and the elastic sheet undergoes only a small amount of elastic deformation. When turning, the windshields on the two adjacent carriages will be squeezed toward the inner end of the turn, which is fed back to this solution, that is, the windshields are deflected. With the cooperation of the connecting buckle, the two adjacent windshields are still in contact, and the elastic sheet produces a larger elastic deformation. After the turn, the elastic sheet releases most of the elastic force, causing the windshield to deflect in the opposite direction and reset;

[0021] That is to say, in this solution, whether it is moving in a straight line or turning, the windshields on two adjacent carriages or locomotives are tightly fitted, with a higher degree of simulation, and at the turn, the windshields will undergo corresponding deflection according to the turning radius, and the two adjacent windshields will maintain close contact, so that the end of the windshield facing the inside of the turn will not be squeezed and hard contact will not occur, and the carriage or locomotive will not derail due to excessive squeezing. In addition, in this solution, the effect of maintaining the windshield in close contact can be achieved only through the cooperation of the connecting frame, the connecting buckle and the elastic sheet, and the structure is simpler.

[0022] 2. In this solution, the setting of the protrusion, when turning, no matter which side you turn, when the hook is deflected, the deflection trajectory is composed of two parts, one is the relative displacement between the hook and the arc surface of the protrusion, and the other is the deflection of the hook relative to the arc surface. The arc surface setting formed by the rounded corners of the protrusion can make the displacement and deflection smoother;

[0023] Furthermore, the cooperation between the protrusion and the hook claw has a certain effect of limiting and increasing the deflection angle of the windshield, and the inclination angle of the side slopes on both sides of the protrusion is the maximum inclination angle of the windshield swing.

[0033] Embodiment 1

[0034] Reference Figure 1-Figure 5 A track model close-fitting simulation windshield comprises a fixed frame door 1 and a connecting frame 2 and an elastic sheet 5 arranged at the end of a carriage or a locomotive, wherein the connecting frame 2 is located on the side of the fixed frame door 1 facing the outside, and the fixed frame door 1 is fixedly arranged at the end of the carriage or the locomotive, and a connecting buckle 3 is arranged on the side of the connecting frame 2 facing the fixed frame door 1, and a hook is arranged at the end of the connecting buckle 3 and the hook passes through an avoidance notch 101 arranged on the fixed frame door 1 and then hooks the fixed frame door 1, and the connecting buckle 3 is restricted by the avoidance notch 101 to move in the vertical direction, but can swing in the horizontal direction. Preferably, two groups of connecting buckles 3 are arranged and are respectively located on the upper and lower sides of the connecting frame 2.

[0035] The elastic sheet 5 has elastic properties, for example, it is made of an elastic metal sheet. The elastic sheet 5 is located on the side of the fixed frame door 1 facing the interior of the vehicle. Initially, the hook hooks the fixed frame door 1 and the elastic sheet 5 is in contact with the hook. Preferably, the elastic sheet 5 can be as follows Figure 5 As shown, the middle can be hollowed out to form a U-shape, or the middle can be not hollowed out to form a rectangle.

[0036] A windshield 4 is provided on the side of the connecting frame 2 facing the outside, and the windshields 4 on two adjacent carriages or locomotives are in contact with each other. The windshield 4 can be consistent with the real train, and can imitate the real train windshield. The windshield required in the cost plan can be made in proportion, for example, it can be a simulated metal windshield, a simulated rubber windshield, or a simulated folding shed windshield.

[0037] Working process of embodiment 1:

[0038] When the vehicle model moves on the straight section of the track, the windshields 4 on two adjacent carriages or locomotives are in contact with each other without forming a gap, and the elastic sheet 5 undergoes only a small amount of elastic deformation;

[0039] When the vehicle model turns on the track, the two adjacent carriages or locomotives are connected by the hook and will not be disconnected. Then the windshields on the two adjacent carriages or locomotives will be squeezed toward the inner side of the turn, which is fed back to the present solution, that is, the windshield 4 is deflected. However, due to the presence of the connecting buckle 3 and the elastic sheet 5, the two adjacent windshields 4 are still in contact, and the elastic sheet 5 is further compressed. When the vehicle model finishes turning and returns to the straight section of the track, the elastic sheet 5 releases most of the elastic force, causing the windshield 4 to deflect in the opposite direction and reset.

[0040] In summary, in the present solution, whether on a straight section of the track or at a bend in the track, the windshields between two adjacent carriages or locomotives are tightly fitted, with a higher degree of simulation, and at a bend, the windshields will deflect accordingly according to the turning radius, and two adjacent windshields 4 will maintain close contact, so that there will be no squeezed hard contact at the end of the windshield 4 facing the inner side of the turn, and the derailment of the carriage or locomotive will not occur. In addition, in the present solution, the windshield can maintain close contact only through the cooperation of the connecting frame 2, the connecting buckle 3 and the elastic sheet 5, and the structure is simpler.

[0041] Embodiment 2

[0042] Reference Figure 5 and Figure 6 A protrusion 102 extends from one side of the fixed frame door 1 toward the interior of the carriage, and the side of the protrusion 102 facing the interior of the carriage is composed of a mid-plane and a side inclined surface, wherein two side inclined surfaces are provided and are respectively located on both sides of the mid-plane along the extension direction of the carriage, and the distance between the two side inclined surfaces decreases along the extension direction of the carriage and in the direction from the connecting frame 2 to the fixed frame door 1. The hook of the connecting buckle 3 contacts the protrusion 102. Initially, the hook contacts the mid-plane of the protrusion 102. Preferably, the edge where the side inclined surface contacts the mid-plane is rounded. When turning, no matter which side you turn to, when the hook deflects, the deflection trajectory can be composed of two parts, one part is the relative displacement of the hook and the arc surface, and the other part is the deflection of the hook relative to the arc surface. The arc surface can make the displacement and deflection smoother.

[0043] Furthermore, the side slope of the projection 102 matches the maximum deflection angle of the windshield. With the cooperation of the projection and the hook, the deflection angle of the windshield can be increased and the windshield can be limited from protruding too much from the vehicle compartment or body.

[0044] Furthermore, since two connecting buckles 3 are provided, two protrusions 102 are also provided correspondingly and are respectively located at the upper and lower sides of the fixed frame door 1 .

Although the present invention has been disclosed as a preferred embodiment as above, it is not intended to limit the present invention. Any technical personnel in this field can make some changes or modify the technical contents disclosed above into equivalent embodiments without departing from the scope of the technical solution of the present invention.
