Description

Technical Field

[0001] The utility model relates to the technical field of rail vehicles, and more specifically to a communication antenna shell and an antenna assembly suitable for rail trains. Background Art

[0002] In order to meet the 5G communication quality and application requirements of rail trains, the spacing between antenna oscillators in 5G communication is much larger than that of previous 4G communication. Correspondingly, the outer shell volume of the antenna assembly becomes larger.

[0003] Due to the high speed of the rail trains currently in operation, the 5G antennas currently used in trains have large wind resistance and are easily broken by foreign objects during operation, resulting in damage to the outer shell, which in turn leads to a decrease or loss of antenna communication quality. For example, trains running in windy and sandy areas, and trains running in extreme weather (such as heavy rain, hail, sandstorms, etc.) all have the above problems.

[0004] In addition, if the outer shell of the 5D communication antenna assembly in the current existing technology is damaged, the antenna vibrator and other components inside will be exposed. Therefore, once the outer shell is damaged, it needs to be replaced immediately as a whole, which results in a large workload and low efficiency in daily maintenance of the train.

[0005] In order to ensure the service life of the antenna assembly, the commonly used method is to increase the thickness of the shell to increase its strength and rigidity. Although the above method can extend the service life of the antenna assembly to a certain extent and reduce the workload of daily maintenance, the increase in the thickness of the shell will lead to an increase in its overall weight, which is contrary to the current mainstream of lightweight and energy saving. At the same time, the corresponding equipment cost will also increase. In addition, as the weight of the shell increases, it will also increase the difficulty of maintenance personnel's maintenance work after damage. Utility Model Content

[0052] In the prior art, the shell of the 5G antenna assembly on top of the rail train is thick and heavy, the equipment cost is high, the daily maintenance and replacement are difficult, and the maintenance workload is large.

[0053] In view of this, the utility model provides a communication antenna housing and antenna assembly suitable for rail trains. By dividing the housing into two layers, an inner layer and an outer layer, the functions of absorbing energy and reducing wind resistance and protecting installed components are respectively provided, thereby improving the overall service life and reducing the difficulty and workload of daily maintenance.

[0055] According to the inventive concept of one aspect of the utility model, a communication antenna housing suitable for a railway train is provided, such as Figures 1 to 3 As shown, the communication antenna housing includes an inner shell 1 and an outer shell 2. The inner shell 1 includes an inner shell body 11 and a mounting plate 12. The inner shell body 11 has an installation space for installing the communication antenna assembly, and the inner shell body 1 is made of a rigid material. The mounting plate 12 extends vertically outward from the bottom edge of the inner shell body 1 to form a flange-like structure, and the mounting plate 12 is suitable for connecting to the top of the rail vehicle. The outer shell 2 is covered on the outside of the inner shell body 11, and the outer shell 2 is a streamlined structure. The outer shell 2 is made of energy-absorbing material, and an isolation space for energy absorption and buffering is provided between the outer shell 2 and the inner shell body 11.

[0056] In this embodiment, the outer shell of the antenna assembly is divided into two layers, the outer shell uses energy-absorbing materials to absorb impact energy and reduce wind resistance, the inner shell is used to protect and fix the antenna vibrator and other components therein, and a buffer space is reserved between the inner and outer layers for elastic deformation of the outer shell, thereby improving the anti-collision function of the antenna assembly, and the inner shell can still provide a certain degree of protection for the antenna vibrator and other components after the outer shell is damaged. In subsequent maintenance work, only the outer shell needs to be replaced, which reduces the maintenance workload and ensures the working quality and work efficiency of the antenna assembly. In addition, the two layers of the inner and outer shells can focus on the two directions of easy integration and installation and streamlined wind resistance, respectively, with better effects, lower overall cost, and low maintenance cost and workload.

[0057] According to some embodiments of the present invention, a mounting hole 13 is formed on the mounting plate 12 , and the mounting hole 13 is a connection node between the mounting plate 12 and the roof of the rail train.

[0058] According to some optional embodiments of the present invention, the mounting plate 12 is connected to a reserved structure (such as a base) of an antenna assembly on the roof of a rail vehicle through mounting holes 13 and bolts 6 .

[0059] According to some alternative embodiments of the present invention, the mounting plate 12 is connected to a reserved structure (such as a base) of an antenna assembly on the roof of a rail vehicle by gluing with an adhesive layer.

[0060] According to some alternative embodiments of the present invention, the mounting plate 12 is detachably connected to a reserved structure (such as a base) of an antenna assembly on the roof of a rail vehicle via a concave-convex matching limiting structure.

[0061] According to some optional embodiments of the utility model, the connecting column 4 arranged inside the outer shell 2 is provided with an internal threaded hole, and the outer shell 2 and the mounting plate 12 are connected through the connecting column 4 in conjunction with the mounting hole 13 and screws, wherein the bottom edge of the outer shell 2 abuts against the mounting plate 12 to maintain the relative sealing of the buffer space between the outer shell 2 and the inner shell body 11, thereby reducing the wind resistance during the operation of the rail train.

[0062] According to some optional embodiments of the present invention, the shell 2 is made of energy-absorbing material, for example, thin-walled metal, carbon fiber composite material, etc., and the shell 2 undergoes plastic deformation when the external impact force exceeds a certain range.

[0063] In this embodiment, the outer shell 2 remains streamlined under normal working conditions to reduce wind resistance during rail train operation; when foreign objects hit the outer shell 2, the outer shell 2 undergoes a certain plastic deformation to absorb energy to protect the inner shell 11 located inside the outer shell 2 and the components inside the inner shell 11.

[0064] According to some optional embodiments of the utility model, the inner shell body 11 is made of rigid materials, and the rigid materials include metals (such as steel, aluminum, etc.), metal alloys (such as aluminum alloys, magnesium alloys, titanium alloys, etc.), polymer materials (such as carbon fiber composites, glass fiber materials, etc.), metal-based composites, ceramic-based composites, polymer-based composites, etc.

[0065] In this embodiment, the inner shell 11 has a certain rigidity and strength, which is used to provide an installation space and a support point for components such as the antenna vibrator. When the inner shell 11 is impacted by external force, it can maintain its original shape within a certain range without deformation, thereby ensuring a stable antenna working space to maintain the normal operation of the 5G antenna.

[0066] According to some optional embodiments of the present invention, the mounting plate 12 vertically extends outward from the bottom edge of the inner shell body 11. Optionally, the outer contour of the cross section of the mounting plate 12 is a rectangle, a rounded rectangle, an ellipse, etc.

[0067] According to some optional embodiments of the present invention, the mounting hole 13 is a countersunk hole to facilitate the installation of screws.

[0068] According to some embodiments of the present invention, the communication antenna shell further includes a buffer layer 3 , which is sandwiched between the inner shell 11 and the outer shell 2 , and is made of a flexible material.

[0069] According to some embodiments of the present invention, the buffer layer 3 is a honeycomb structure or a porous structure.

[0070] According to some optional embodiments of the present invention, the material of the buffer layer 3 includes polyethylene foam cotton (PEP), polyethylene foam, high-foam polypropylene, natural rubber, synthetic rubber, plastic elastomer, latex, foam aluminum, etc.

[0071] In this embodiment, when the outer shell 2 undergoes plastic deformation to absorb energy upon impact, the deformed area of ​​the outer shell 2 compresses the buffer layer 3 in the corresponding area, and the buffer layer 3 further distributes the impact force to the surrounding area, thereby preventing the outer shell 2 from undergoing excessive plastic deformation and colliding with the inner shell 11, thereby affecting the shape of the inner shell 11.

[0072] According to some embodiments of the present invention, the shell 2 is a semi-ellipsoidal structure, and the windward surface areas at both ends of the shell 2 are set as thickened areas C1, wherein the thickness of the thickened area C1 decreases with increasing height.

[0073] In this embodiment, the thickened area C1 is the windward area of ​​the shell 2, that is, the area where the shell 2 is more likely to be hit, and the thickness of this area is increased to enhance the anti-impact ability of the shell 2. At the same time, in accordance with the streamlined shape of the shell 2, such as a semi-ellipsoidal shape, the impact form of the front ends of both ends is generally a frontal impact, and the thickness of the corresponding area is the largest. As the height of the front end position of the shell 2 increases, the impact form is also changed from a frontal impact to a side collision, and the impact component force perpendicular to the shell 2 gradually decreases, and the thickness of the shell 2 is correspondingly gradually reduced, which can ensure that the overall anti-impact ability of the shell 2 is not reduced, and the material amount (that is, weight) of the shell 2 is reduced as much as possible, thereby reducing the production cost, meeting the demand for lightweight, and reducing the daily maintenance work of subsequent staff.

[0074] According to some embodiments of the present invention, the housing 2 further comprises a connecting column 4 , which is disposed in a non-thickened area on the inner wall of the housing 2 , and is suitable for connecting to the mounting plate 12 .

[0075] In this embodiment, the connection node between the housing 2 and the mounting plate 12 is the location of the connection column 4. Optionally, the number of the connection columns 4 is multiple, for example, 4, 6 or more. Setting the connection node in the non-thickened area can ensure that the thickened area, that is, the frontal impact area (or the area near the frontal impact area) has sufficient conditions for plastic deformation to absorb the energy of the impact.

[0076] According to some embodiments of the present invention, the installation space includes a rectangular parallelepiped equipment area C2 located in the middle and triangular prism-shaped buffer areas C3 located at both ends of the equipment area.

[0077] In this embodiment, the main components of the antenna assembly are installed in the equipment area C2, and no equipment is installed in the buffer area C3, or some unimportant equipment or cables with low anti-collision requirements are installed, thereby further reducing the impact of collision on the components of the antenna assembly.

[0078] In the embodiment of the utility model, the impact of foreign body impact on the antenna assembly is mitigated by multi-level anti-collision measures, so as to ensure the normal operation of the antenna assembly to the greatest extent. Specifically, when a foreign body impact occurs, the outer shell 2 is first used for energy absorption and shock reduction; when the impact force exceeds the first preset threshold, the impact area of ​​the outer shell 2 undergoes plastic deformation to further absorb energy and reduce shock, and at the same time, the buffer layer disperses and evenly distributes the impact force to reduce the impact; when the impact force exceeds the second preset threshold, the foreign body or the plastically deformed outer shell 2 continues to impact the buffer zone C3 of the inner shell 11, and the inner shell 11 absorbs the remaining impact force; when the impact force exceeds the third preset threshold, the buffer zone C3 of the inner shell 11 undergoes plastic deformation to absorb energy. In summary, the communication antenna shell of the embodiment of the utility model can ensure the normal operation of the electrical components of the antenna assembly installed in the equipment area C2 to the greatest extent through the layered multi-level anti-collision, energy absorption and shock absorption structure, and ensure the normal operation of 5G communication of the rail train in operation.

[0079] According to some embodiments of the utility model, the outer shell 2 is a semi-ellipsoidal structure, which can ensure that the inner shell body 11 provides a narrow and long installation space, that is, a narrow and long equipment area C2, thereby ensuring that the antenna vibrator has sufficient installation spacing to ensure communication quality.

[0080] According to some embodiments of the present invention, the inner shell 1 further includes reinforcing ribs 5 , which are arranged on the side surface and / or the top surface of the inner shell shell 11 .

[0081] According to some embodiments of the present invention, the reinforcing rib 5 may be disposed on the inner side surface of the inner shell body 11 , or may be disposed on the side surface of the inner shell body 11 .

[0082] According to some embodiments of the present invention, there are multiple reinforcing ribs 5, and the multiple reinforcing ribs 5 are cross-arranged in the horizontal and vertical directions to form a grid shape.

[0083] In this embodiment, if Figure 3 As shown, the reinforcing ribs 5 are arranged horizontally and vertically at the bottom of the inner side of the inner shell body 11 (corresponding to the top of the inner side of the inner shell body 11 under normal use), and the reinforcing ribs 5 are arranged vertically and at intervals on the side inside the inner shell body 11.

[0084] Figure 4 is a perspective view of an inner shell of a communication antenna housing suitable for a rail train according to another exemplary embodiment of the utility model; Figure 5 yes Figure 4 A perspective view of the inner shell from another perspective is shown.

[0085] According to some embodiments of the present invention, Figure 4 and Figure 5As shown, there are two inner shell bodies 11, which are arranged side by side. The heights of the two opposite sides of the two inner shell bodies 11 are lower than the heights of the two opposite sides. The bottom edges of the two opposite sides of the two inner shell bodies 11 are connected by a transition plate 14 to connect the two installation spaces.

[0086] In this embodiment, a group of 5G communication antenna components can be installed in two installation spaces respectively, one group of antenna components is the main working component, and the other group of antenna components is used as a backup; the antenna vibrators of a group of antenna components can also be installed in two installation spaces respectively to further improve the 5G communication effect of the antenna components.

[0087] According to some embodiments of the present invention, reinforcing ribs 5 are also provided on the transition plate 14 to further improve the overall strength of the inner shell 11 .
