Description

Technical Field

[0001] This utility model relates to the field of electromagnetic shielding technology, specifically to an electromagnetic shielding roof for a mobile cabin based on PEEK material. Background Technology

[0002] Mobile modular units are often used in highly sensitive scenarios such as medical and military applications. The internal electronic equipment, such as CT scanners or communication systems, is easily affected by external electromagnetic waves. Therefore, a shielded roof that can prevent electromagnetic interference is usually installed on the top of the mobile modular unit. This can also suppress the leakage of internal signals and improve the confidentiality of the communication system.

[0003] In the current installation process of electromagnetic shielding roofs for mobile modular shelters, a stacked installation method is commonly used. However, this method has significant technical drawbacks. During installation, the bottom of the roof must be precisely aligned with the top of the modular shelter. Because the contact surfaces are perfectly matched and have a low coefficient of friction, even after initial positioning, millimeter-level displacement can easily occur during subsequent riveting and fastening. This micro-displacement not only affects assembly efficiency but also leads to rivet hole misalignment, causing structural stress concentration and directly impacting the overall stability of the roof system. Furthermore, the protective performance of this special roof is limited by the durability of the surface treatment process. The composite conductive coating applied to achieve electromagnetic shielding faces severe challenges when exposed to the outdoor environment for extended periods. Ultraviolet radiation from the sun accelerates the aging of the polymer binder. This gradual degradation process eventually causes the conductive dielectric layer to detach, resulting in an exponential decrease in shielding effectiveness. Simultaneously, the roof structure is exposed to environmental corrosion, shortening its overall service life by 30%-40% compared to the design specifications. Utility Model Content

[0004] The purpose of this invention is to provide an electromagnetic shielding roof for mobile shelters based on PEEK material, in order to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an electromagnetic shielding roof for a mobile cabin based on PEEK material, comprising a roof body, a groove at the bottom of the roof body, the roof body being mounted on the top of the mobile cabin via the groove, a cover being provided on one side of the top of the roof body, a forward and reverse motor being installed at one end of the cover, a rotating shaft being provided at the output end of the forward and reverse motor, a tarpaulin being wound around the outside of the rotating shaft, a sliding plate being fixedly connected to the end of the tarpaulin, electric sliding rails being provided on both side walls of the roof body, and vertical strips being fixedly connected to both sides of the bottom of the roof body, with round holes at the bottom of the vertical strips.

[0006] Preferably, the bottom of the mobile cabin has fixing rivets on both sides, and the fixing rivets pass through the bottom of the vertical strip through round holes. The roof body is connected to the movable cover of the mobile cabin through the vertical strip.

[0007] Preferably, one side wall of the cover has an opening, and the tarpaulin is connected to the cover through the opening.

[0008] Preferably, the contact surface between the skateboard and the roof body is provided with a scraper.

[0009] Preferably, the bottom end of the skateboard is provided with sliders on both sides for use with the electric slide rail. The skateboard is slidably connected to the electric slide rail through the sliders, and the skateboard is slidably connected to the roof body through the electric slide rail.

[0010] Preferably, a magnetic shielding plate is provided at the top of the inner side of the groove.

[0011] Preferably, a PLC controller is electrically connected to one side of the reversible motor, and the rotating shaft is rotatably connected to the cover via the reversible motor.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. This electromagnetic shielding roof for mobile shelters based on PEEK material features an inwardly recessed groove. When the shielding roof is aligned with the mobile shelter, it will directly interlock and cover the top of the mobile shelter. This prevents the roof from slipping along the top surface of the mobile shelter, even with a low coefficient of friction. Furthermore, the vertical bars and round holes allow the roof to extend downwards to both sides of the mobile shelter for secure installation, facilitating the installation and fixation of the roof while also improving the overall stability of the roof.

[0014] 2. This mobile shelter with electromagnetic shielding, based on PEEK material, uses a cover, tarpaulin, sliding plate, and forward / reverse motor. When the roof is exposed to the sun outdoors, the electric sliding rail and the forward / reverse motor can be activated, causing the sliding plate to pull the tarpaulin out of the cover. At this time, the tarpaulin can cover the surface of the roof, reducing the ultraviolet rays shining on the roof surface, slowing down the aging of the conductive layer on the roof surface, and thus slowing down the decay of the shielding effectiveness of the conductive layer on the roof surface, which is beneficial to extending the service life of this shielding roof.

[0023] like Figures 1 to 4As shown in the figure, the electromagnetic shielding roof for a mobile shelter based on PEEK material in this embodiment includes a roof body 2. An embedding groove 11 is provided at the bottom end of the roof body 2. The roof body 2 is arranged on the top of the mobile shelter 1 through the embedding groove 11. One side of the top end of the roof body 2 is provided with a cover shell 3. A forward and reverse motor 9 is installed at one end of the cover shell 3. A rotating shaft 14 is arranged at the output end of the forward and reverse motor 9. A tarpaulin 4 is wound around the outside of the rotating shaft 14. The end of the tarpaulin 4 is fixedly connected with a slide plate 5. Electric slide rails 6 are arranged on both side walls of the roof body 2. Vertical bars 7 are fixedly connected to both sides of the bottom end of the roof body 2. Circular holes 10 are provided at the bottom of the vertical bars 7.

[0024] Specifically, the roof body 2 is made of lightweight PEEK material, which can effectively reduce the total mass of the roof body 2, thereby reducing the overall load of the mobile shelter 1 and making it more conducive to the movement of the mobile shelter 1. The function of the embedding groove 11 is to enable the roof to be nested on the top of the mobile shelter 1, reduce the displacement between the roof and the mobile shelter 1, and make the connection between the roof and the mobile shelter 1 closer and more stable. The function of the cover shell 3 is to protect the wound tarpaulin 4. The function of the forward and reverse motor 9 is to enable the rotating shaft 14 to rotate forward and backward, so as to realize the unfolding and winding of the tarpaulin 4. The tarpaulin 4 is a PVC coated tarpaulin 4, which has good flexibility, fold resistance and anti-aging performance. The front shape of the slide plate 5 is "冂" shaped, so that the bottom surface of the slide plate 5 can fit and slide on the top surface of the roof body 2, and at the same time can pull out the end of the tarpaulin 4 from the cover shell 3, so as to realize the unfolding of the tarpaulin 4 on the roof. The function of the electric slide rail 6 is to drive the slide plate 5 to move along the roof body 2. The function of the vertical bar 7 is to enable the installation structure of the roof to extend to the bottom of the mobile shelter 1, which is more convenient for the disassembly and assembly of the roof. At the same time, the vertical bar 7 can increase the contact surface between the roof and the mobile shelter 1, which is beneficial to improving the stability after the roof is installed.

[0025] Furthermore, fixing rivets 8 penetrate through both sides of the bottom of the mobile shelter 1. The fixing rivets 8 penetrate through the bottom of the vertical bar 7 through the circular holes 10. The roof body 2 is movably covered and connected with the mobile shelter 1 through the vertical bar 7. The function of the fixing rivets 8 is to realize the fixed locking between the roof and the mobile shelter 1, so that the roof and the mobile shelter 1 become a complete whole.

[0026] Furthermore, an opening 15 is provided on one side wall of the cover shell 3. The tarpaulin 4 is connected through the opening 15 and the cover shell 3. The function of the opening 15 is to enable the tarpaulin 4 to be drawn out from the inside of the cover shell 3, which is conducive to the subsequent unfolding of the tarpaulin 4.

[0027] Furthermore, a scraping strip 13 is arranged on the fitting surface between the slide plate 5 and the roof body 2. When the slide plate 5 slides along the top surface of the roof, the scraping strip 13 cleans the dust particles on the roof, so as to facilitate the cleaning and maintenance of the roof.

[0028] Furthermore, the bottom of the skateboard 5 is equipped with sliders on both sides for use with the electric slide rail 6. The skateboard 5 is slidably connected to the electric slide rail 6 through the sliders, and the skateboard 5 is slidably connected to the roof body 2 through the electric slide rail 6. The function of the skateboard 5 is to pull out the end of the tarpaulin 4 and unfold it, so that the tarpaulin 4 can be kept stretched and unfolded at the top of the roof, thereby achieving continuous sun protection for the roof.

[0029] Furthermore, a magnetic shielding plate 12 is provided on the top of the inner side of the groove 11. The function of the magnetic shielding plate 12 is to block or weaken the propagation of the magnetic field, thereby improving the electromagnetic shielding effect of the roof of the vehicle.

[0030] Furthermore, a PLC controller is electrically connected to one side of the reversible motor 9. The rotating shaft 14 is rotatably connected to the cover 3 through the reversible motor 9. The PLC controller can control the forward or reverse rotation of the reversible motor 9, thereby facilitating the control of the rotating shaft 14 and the tarpaulin 4 by the reversible motor 9.

[0031] The usage method of this embodiment is as follows: When using the electromagnetic shielding roof of the mobile cabin 1 based on PEEK material, the roof body 2 needs to be nested into the top of the mobile cabin 1 through the groove 11. At this time, the vertical strips 7 at the bottom of the roof body 2 will be attached to both sides of the mobile cabin 1, and the magnetic shielding plate 12 in the groove 11 will be tightly attached to the top of the mobile cabin 1. Then, a tool can be used to pass the fixing rivets 8 through the round holes 10 on the vertical strips 7, so that the vertical strips 7 are fixed to the top of the mobile cabin 1. Then, the roof body 2 is connected to the power supply inside the mobile cabin 1. When the mobile cabin 1 needs to be parked in an unobstructed outdoor location for a long time, it can be controlled via PLC. The controller controls the forward and reverse motor 9 to rotate in the forward direction, causing the shaft 14 to drive the tarpaulin 4 to rotate. At the same time, the electric slide rail 6 is activated, causing the electric slide rail 6 to drive the slide plate 5 to slide away from the cover 3. At this time, the tarpaulin 4 will be pulled out and unfolded under the pull of the slide plate 5. After the tarpaulin 4 is fully unfolded on the top of the roof body 2, it can cover the roof, making it difficult for ultraviolet rays to directly hit the conductive coating on the roof surface. When it is necessary to roll up the tarpaulin 4, the PLC controller will control the forward and reverse motor 9 to rotate in the reverse direction, so that the tarpaulin 4 is rolled into the cover 3 through the opening 15. At the same time, the slide plate 5 will also slide back to one side of the cover 3 under the drive of the electric slide rail 6.

[0032] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
