A highly collapsible vehicle-mounted antenna shelter

Abstract

This invention provides a height-reducible vehicle-mounted antenna container. The container's top panel is divided into left and right sections, and the surrounding walls are divided into front, rear, left, and right sections. The front and rear sections move vertically up and down along the inner walls of the container, while the left and right side panels fold and flip along with the top panels, ultimately folding side-by-side and storing on the outer walls of the container. The width on each side increases by approximately the thickness of two container wall panels. The hatch is locked and unlocked via an electrically controlled permanent magnet when open or closed. Sealing strips are installed at the gaps between the closed sections to achieve a good seal. This invention is compact, well-sealed, and has a locking function. A single motor operation achieves both opening and folding of the hatch, resulting in high efficiency. The top of the container can be completely opened, reducing the overall height of the container while maintaining the width within limits, meeting the needs of hoisting and transporting large equipment and performing tasks on highways.

Description

Technical Field

[0001] This invention relates to the field of antenna technology, and more specifically to a vehicle-mounted antenna container with a height that can be reduced. Background Technology

[0002] The vehicle-mounted antenna container provides transportation and protection for telemetry antennas and is an important component of the vehicle-mounted station. When the antenna is in transit, the container provides protection against rain and dust; when the antenna is in operation, the container's top cover can open automatically without obstructing the antenna's signal transmission and reception.

[0003] Currently, there are two main types of commonly used shelter opening mechanisms: one is an electric flip-top mechanism, which uses a motor to rotate the top cover via a hinge, allowing it to move between the closed and open positions; the other is an electric sliding mechanism, which uses a nut and screw to slide the top cover back and forth, opening and closing the shelter's top cover. Other types of shelter opening mechanisms are also available, generally designed for small and medium-sized antennas with varying opening sizes, locations, and special operating conditions.

[0004] However, when adapting to large-aperture antennas, even after the antenna is fully extended with the canopy fully open, the lower edge of the antenna remains below the highest point of the canopy. This prevents the antenna from achieving continuous 360-degree operation. Furthermore, the opening width of the vehicle-mounted antenna canopy cannot exceed the width of the vehicle's lane, and the canopy must automatically open and reliably lock while the canopy is in motion. Existing technologies cannot meet these requirements. Therefore, existing technologies cannot satisfy the requirements of a complex opening mechanism, large unfolded dimensions, and high reliability. A vehicle-mounted antenna canopy with a lower overall height after opening, suitable unfolded dimensions, and automatic opening and reliable locking while in motion is needed. Summary of the Invention

[0005] This invention addresses the problems of existing container opening mechanisms, such as complex structure, large unfolded size, low reliability, and inability to meet the requirements of large-aperture antennas. It provides a height-reducible vehicle-mounted antenna container, dividing the top panel into left and right sections. The surrounding walls of the top panel are divided into front, rear, left, and right sections. The front and rear sections move vertically up and down along the inner walls of the container, while the left and right side panels fold and flip along with the top panels, ultimately folding side-by-side and storing on the outer walls of the container. This increases the width of each side by approximately the thickness of two container wall panels. The open and closed states are controlled by an electrically controlled permanent magnet for locking and unlocking. Sealing strips are installed at the gaps between the closed sections to achieve a good seal. This mechanism features a reliable, compact mechanical structure and excellent sealing performance, enabling large telemetry antennas to perform tasks 360 degrees in mobile environments.

[0006] The present invention provides a vehicle-mounted antenna container with a height that can be lowered, comprising a container base plate, an antenna fixedly connected to the upper part of the container base plate in a retracted or extended state, fixed plate assemblies respectively connected to the periphery of the container base plate, a movable plate assembly respectively movably connected to the fixed plate assembly and including a top plate, and a pushing mechanism and a locking mechanism connected to both the fixed plate assembly and the movable plate assembly.

[0007] When the vehicle-mounted antenna cabin is deployed, the locking mechanism unlocks. Under the push of the pushing mechanism, the left and right plates of the moving plate assembly flip outwards, causing the top plate to open to both sides and fold into the outer wall of the fixed plate assembly. The front and rear plates of the moving plate assembly move downwards into place along the inner walls of the front and rear plates of the fixed plate assembly. The locking mechanism locks the moving plate assembly. At this time, the height of the vehicle-mounted antenna cabin is only the height of the fixed plate assembly. The antenna is deployed, and the lowest point of the antenna's parabolic surface is higher than or level with the top of the fixed plate assembly.

[0008] When the vehicle-mounted antenna container is retracted, the antenna retracts back into the fixed plate assembly, the locking mechanism unlocks, and under the push of the pushing mechanism, the front and rear plates of the movable plate assembly move upward along the inner walls of the front and rear plates of the fixed plate assembly, respectively. The left and right plates of the movable plate assembly flip inward and drive the top plate to unfold inward. The locking mechanism locks the movable plate assembly, and the container is closed.

[0009] The height-reducible vehicle-mounted antenna container of the present invention, in a preferred embodiment, includes a fixing plate assembly comprising a left fixing plate, a front fixing plate, a right fixing plate and a rear fixing plate respectively connected to the four sides of the container floor.

[0010] The movable plate assembly includes a left movable plate, a front movable plate, a right movable plate, a rear movable plate, a left outer support rod connected to the outer wall of the left movable plate, a left hinge seat connected to the bottom of the left outer support rod, a left top plate connected to the top of the left movable plate via a hinge, a right outer support rod connected to the outer wall of the right movable plate, a right hinge seat connected to the bottom of the right outer support rod, and a right top plate connected to the top of the right movable plate via a hinge. The left hinge seat is fixedly connected to the outer wall of the left fixed plate, and the right hinge seat is fixedly connected to the outer wall of the right fixed plate. The included angle between the left top plate and the left movable plate is variable, and the included angle between the right top plate and the right movable plate is variable.

[0011] The pushing mechanism includes a left motor connected to the inner wall of the left fixed plate, a left inner support rod connected to the output end of the left motor, and a left hinge seat connected to the other end of the left inner support rod. The left hinge seat is fixed to the inner wall of the left top plate.

[0012] The left motor drives the left inner support rod to rotate to the left along the left motor, causing the left top plate, left moving plate and left outer support rod to flip outward. The included angle between the left top plate and left moving plate decreases until the left outer support rod rotates 180° and sticks to the outer wall of the left fixed plate. The left moving plate and left top plate are folded and stand on the outside of the left outer support rod in sequence.

[0013] The height-reducible vehicle-mounted antenna container of the present invention, as a preferred embodiment, includes an inner electro-electric permanent magnet connected to the upper middle part of the inner wall of the front moving plate and the rear moving plate respectively, embedded irons pre-embedded at both ends of the inner and outer sides of the left top plate and the right top plate, and an outer electro-electric permanent magnet connected to both ends of the outer wall of the left fixed plate and the right fixed plate respectively.

[0014] When the vehicle-mounted antenna container is deployed, the internal electro-controlled permanent magnets demagnetize, and the left and right top panels unfold to the sides and flip up to be stored on the outer walls of the left and right fixed plates respectively. The external electro-controlled permanent magnets then magnetically attract the left and right top panels.

[0015] When the vehicle-mounted antenna container is retracted, the external electro-magnetic permanent magnet is demagnetized, and the left and right top panels retract towards the middle and overlap above the antenna. The internal electro-magnetic permanent magnet then magnetically attracts the left and right top panels.

[0016] In a preferred embodiment of the height-reducible vehicle-mounted antenna cabin of the present invention, a water-retaining eave is connected to the upper right end of the left side top plate and the middle left end of the right side top plate. The water-retaining eave is a plate-shaped structure with a thickness less than that of the left or right side top plate. A sealing strip is provided on the water-retaining eave of the right side top plate. When the vehicle-mounted antenna cabin is closed, the water-retaining eave of the left side top plate overlaps the sealing strip.

[0017] When the vehicle-mounted antenna container is deployed, the left top panel deploys first, followed by the right top panel; when the antenna is retracted, the right top panel retracts first, followed by the left top panel.

[0018] In a preferred embodiment, the height-reducible vehicle-mounted antenna cabin of the present invention further includes a right motor connected to the inner wall of the right fixed plate, a right inner support rod connected to the output end of the right motor, and a right hinge seat connected to the end of the right inner support rod. The right hinge seat is fixed to the inner wall of the right top plate.

[0019] The right motor drives the right inner support rod to rotate to the right along the right motor, causing the right top plate, the right moving plate, and the right outer support rod to flip outward. The included angle between the right top plate and the right moving plate decreases until the right outer support rod rotates 180° and sticks to the outer wall of the right fixed plate. After the right moving plate and the right top plate are folded, they stand on the outside of the right outer support rod in sequence.

[0020] In a preferred embodiment, the height-reducible vehicle-mounted antenna container of the present invention further includes a front slide rail partially connected to the inner wall of the front movable plate and partially connected to the inner wall of the front fixed plate, and a front electric push rod with its movable end hinged to the bottom of the other side of the front movable plate and its fixed end connected to the inner wall of the front fixed plate.

[0021] The outer wall of the front movable plate is located above the inner wall of the front fixed plate. When the vehicle-mounted antenna container is deployed, the front electric push rod pulls the front movable plate down along the inner wall of the front fixed plate until the front movable plate is completely lower than the front fixed plate. The front slide rail guides the downward pull, and the front electric push rod locks the position of the front movable plate. When the vehicle-mounted antenna container is retracted, the front electric push rod pushes the front movable plate up along the inner wall of the front fixed plate until the bottom of the front movable plate is higher than the top of the front fixed plate. The front electric push rod locks the position of the front movable plate.

[0022] In a preferred embodiment, the height-reducible vehicle-mounted antenna container of the present invention further includes a rear slide rail partially connected to the inner wall of the rear movable plate and partially connected to the inner wall of the rear fixed plate, and a rear electric push rod with its movable end hinged to the bottom of the other side of the rear movable plate and its fixed end connected to the inner wall of the rear fixed plate.

[0023] The outer wall of the rear movable plate is located above the inner wall of the rear fixed plate. When the vehicle-mounted antenna container is deployed, the rear electric push rod pulls the rear movable plate down along the inner wall of the rear fixed plate until the rear movable plate is completely lower than the rear fixed plate. The rear slide rail guides the downward pull, and the rear electric push rod locks the position of the rear fixed plate. When the antenna is retracted, the rear electric push rod pushes the rear movable plate up along the inner wall of the rear fixed plate until the rear movable plate is located at the upper end of the rear fixed plate, and the rear electric push rod locks the position of the rear fixed plate.

[0024] In a preferred embodiment of the height-reducible vehicle-mounted antenna container described in this invention, sealing strips are installed on the top and both sides of the front fixing plate and the right fixing plate.

[0025] In a preferred embodiment of the height-reducible vehicle-mounted antenna container of the present invention, the main bodies of the left and right outer support rods are straight rods, and the connection points with the left and right movable plates are provided with elbows. The number of the left outer support rod, the left hinge seat, the right outer support rod, the right hinge seat, the left motor, the left inner support rod, the left hinge seat, the right motor, the right inner support rod, and the right hinge seat are all two, located at the front and rear ends respectively.

[0026] In a preferred embodiment of the height-reducible vehicle-mounted antenna container described in this invention, the left inner support rod and the right inner support rod can be arc-shaped support rods, zigzag-shaped support rods, or can be composed of multiple segments connected together.

[0027] A height-reducible automatic opening mechanism for a vehicle-mounted container mainly consists of multiple cover panels, a mechanical transmission mechanism, and an electrical control system. The top panel is divided into two sections from left to right. The lowered sections around the top of the side panels are movable covers, consisting of four panels: front, rear, left, and right. The left and right top panels are connected to the left and right side panels inside the container via hinges, allowing the angle between the top and side panels to change during movement. Hinged supports are provided on the left and right side panels and the top panel, further hinged and fixed to the container wall via support rods, forming a four-bar linkage. A motor drives the support rods of the top panel and the container wall to rotate, causing the side panels and top panel to flip outwards together, ultimately folding side-by-side and storing on the outer wall of the container, increasing the width of each side by approximately the thickness of two container wall panels. The front and rear panels move vertically up and down along the inner wall of the container under the action of electric push rods. Embedded irons are located on the left and right side panels and the top panel; in the open or closed state of the covers, electro-controlled permanent magnets are used for attraction, locking, and unlocking. Sealing strips are installed at all gaps in the panel closure to achieve a good sealing effect.

[0028] The objective of this invention can also be further achieved through the following technical measures:

[0029] Furthermore, the motor is fixed to the side wall of the container, and hinge seats are set at the front and rear of the inner side of the top plate. The two are connected by an irregular support rod. The motor directly drives the irregular support rod to rotate, and the irregular support rod can rotate at least 180 degrees. The top plate and the side plate are hinged to each other on the inner side by multiple hinges. The side plate is fixed to the straight support rod on the outside, and the other end of the straight support rod is hinged to the outer wall of the container.

[0030] Furthermore, the front panel is equipped with a linear slide rail and an electric push rod. The slide rail and push rod are fixed to the appropriate position on the inner wall of the container. The output end of the push rod is connected to the front panel by a ball joint, allowing the front panel to slide vertically up and down along the inner wall of the container.

[0031] Furthermore, the rear hatch is equipped with a linear slide rail and an electric push rod. The slide rail and push rod are fixed to the appropriate position on the inner wall of the container. The output end of the push rod is connected to the rear hatch with a ball joint, allowing the rear hatch to slide vertically up and down along the inner wall of the container.

[0032] Furthermore, sealing strips are installed on the top and sides of the front and rear hatches, and a water-retaining eaves are added between the left and right top panels, so that when the hatch is closed, the water-retaining eaves of one top panel press on the sealing strip installed on the water-retaining eaves of the other top panel.

[0033] Furthermore, the left and right top plates are activated sequentially to achieve the sealing of the top water-retaining eaves. When the top plate with the water-retaining eaves is on top, it opens first and closes last. When the top plate with the water-retaining eaves is on the bottom, it opens last and closes first.

[0034] Furthermore, embedded iron is installed at both the inner and outer ends of the top plate, and an electrically controlled permanent magnet is installed in the middle of the top of the front and rear hatches. Multiple electrically controlled permanent magnets are installed on the outside of the container. When the hatch is opened, the embedded iron on the outside of the top plate attracts the electrically controlled permanent magnets on the outside of the container. When the hatch is closed, the embedded iron on the inside of the top plate attracts the electrically controlled permanent magnets on the top of the front and rear hatches.

[0035] Furthermore, the electrically controlled permanent magnet is controlled by electrical signals to determine whether it possesses magnetism, and is equipped with a power supply so that it retains its magnetism even after the power is cut off.

[0036] Furthermore, the linear movement of the front and rear panels and the flipping movement of the left and right panels are independent of each other. They can be moved independently by electrical control without interference, or they can be moved continuously to achieve one-button opening and closing of the cover.

[0037] The present invention has the following advantages:

[0038] (1) The invention divides the top panel of the container into two panels, left and right. The four sides of the top panel are divided into four panels: front, rear, left, and right. The front and rear panels move vertically up and down along the inner wall of the container. The left and right side panels are flipped and folded together with the left and right top panels, and finally folded side by side and stored on the outer wall of the container. The width of each side is increased by about two thicknesses of the container wall panels. The hatch is attracted, locked and unlocked by an electrically controlled permanent magnet when it is open or closed. Sealing strips are installed at the gaps between the closed panels to achieve a good sealing effect. The drive motor completes the opening and folding of the side panels of the container in one operation, and the result is efficient and reliable.

[0039] (2) The top of the cabin can be fully opened after the cover is opened, and the overall height of the cabin is reduced, which meets the requirements for the use of large aperture antennas, and at the same time meets the needs of hoisting, transporting and mobile work of large equipment. It is suitable for situations where the overall height of the cabin needs to be reduced after the cover is opened.

[0040] (3) The present invention is compact in size and well sealed. The width of the cabin does not exceed the limit after the cover is opened. The cover is automatically locked when in place, which meets the requirements of opening the cabin to perform tasks in motor vehicles on the road. It is suitable for situations where the width of the cover is limited. Attached Figure Description

Detailed Implementation

[0053] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0054] Example 1

[0055] like Figures 1-10As shown, a height-reducible vehicle-mounted antenna container includes a container base plate 1, an antenna 2 fixedly connected to the upper part of the container base plate 1 in a retracted or extended state, fixed plate assemblies 3 connected to the four sides of the container base plate 1, movable plate assemblies 4 movably connected to the fixed plate assemblies 3 and including a top plate, and a pushing mechanism 5 and a locking mechanism 6 connected to both the fixed plate assemblies 3 and the movable plate assemblies 4.

[0056] When the vehicle-mounted antenna cabin is deployed, the locking mechanism 6 is unlocked. Under the push of the pushing mechanism 5, the left and right plates of the moving plate assembly 4 flip outwards, causing the top plate to open to both sides and fold and store in the outer wall of the fixed plate assembly 3. The front and rear plates of the moving plate assembly 4 move down into place along the inner walls of the front and rear plates of the fixed plate assembly 3. The locking mechanism 6 locks the moving plate assembly 4. At this time, the height of the vehicle-mounted antenna cabin is only the height of the fixed plate assembly 3. The antenna 2 is deployed, and the lowest point of the parabolic surface of the antenna 2 is higher than or level with the top of the fixed plate assembly 3.

[0057] When the vehicle-mounted antenna container is retracted, the antenna 2 retracts back into the fixed plate assembly 3, the locking mechanism 6 is unlocked, and under the push of the pushing mechanism 5, the front and rear plates of the moving plate assembly 4 move upward along the inner walls of the front and rear plates of the fixed plate assembly 3 respectively, the left and right plates of the moving plate assembly 4 flip inward and drive the top plate to unfold inward, the locking mechanism 6 locks the moving plate assembly 4, and the container is closed.

[0058] The fixing plate assembly 3 includes a left fixing plate 31, a front fixing plate 32, a right fixing plate 33 and a rear fixing plate 34 respectively connected to the four sides of the container floor plate 1;

[0059] The movable plate assembly 4 includes a left movable plate 41, a front movable plate 42, a right movable plate 43, a rear movable plate 44, a left outer support rod 45 connected to the outer wall of the left movable plate 41, a left hinge seat 46 connected to the bottom of the left outer support rod 45, a left top plate 47 connected to the top of the left movable plate 41 via a hinge, a right outer support rod 48 connected to the outer wall of the right movable plate 43, a right hinge seat 49 connected to the bottom of the right outer support rod 48, and a right top plate 4a connected to the top of the right movable plate 43 via a hinge. The left hinge seat 46 is fixedly connected to the outer wall of the left fixed plate 31, and the right hinge seat 49 is fixedly connected to the outer wall of the right fixed plate 33. The included angle between the left top plate 47 and the left movable plate 41 is variable, and the included angle between the right top plate 4a and the right movable plate 43 is variable.

[0060] like Figure 1 , 2As shown in Figures 4, 7, 8, and 10, the pushing mechanism 5 includes a left motor 51 connected to the inner wall of the left fixed plate 31, a left inner support rod 52 connected to the output end of the left motor 51, and a left hinge seat 53 connected to the other end of the left inner support rod 52; a right motor 54 connected to the inner wall of the right fixed plate 33, a right inner support rod 55 connected to the output end of the right motor 54, and a right hinge seat 56 connected to the end of the right inner support rod 55; and is partially connected to the inner wall of the front moving plate 42. The front slide rail 57 is on the wall and part of it is connected to the inner wall of the front fixed plate 32; the front electric push rod 58 has its movable end hinged to the bottom of the other side of the front moving plate 42 and its fixed end connected to the inner wall of the front fixed plate 32; the rear slide rail 59 is partly connected to the inner wall of the rear moving plate 44 and part of it is connected to the inner wall of the rear fixed plate 34; and the rear electric push rod 5a has its movable end hinged to the bottom of the other side of the rear moving plate 44 and its fixed end connected to the inner wall of the rear fixed plate 34.

[0061] The left hinge seat 53 is fixed to the inner wall of the left top plate 47, and the right hinge seat 56 is fixed to the inner wall of the right top plate 4a.

[0062] The left motor 51 drives the left inner support rod 52 to rotate to the left along the left motor 51, causing the left top plate 47, the left moving plate 41, and the left outer support rod 45 to flip outward. The included angle between the left top plate 47 and the left moving plate 41 decreases until the left outer support rod 45 rotates 180° and sticks to the outer wall of the left fixed plate 31. The left moving plate 41 and the left top plate 47 are folded and stand on the outside of the left outer support rod 45 in sequence.

[0063] The locking mechanism 6 includes an inner electro-electric permanent magnet 61 connected to the upper middle part of the inner wall of the front moving plate 42 and the rear moving plate 44 respectively, an embedded iron 62 pre-embedded at both ends of the inner and outer sides of the left top plate 47 and the right top plate 4a, and an outer electro-electric permanent magnet 63 connected to both ends of the outer wall of the left fixed plate 31 and the right fixed plate 33 respectively.

[0064] When the vehicle-mounted antenna container is deployed, the internal electro-controlled permanent magnet 61 demagnetizes, and the left top plate 47 and the right top plate 4a unfold to the sides until they flip and are stored on the outer walls of the left fixed plate 31 and the right fixed plate 33 respectively. The external electro-controlled permanent magnet 63 magnetically attracts the left top plate 47 and the right top plate 4a.

[0065] When the vehicle-mounted antenna container is retracted, the external electro-magnet 63 loses its magnetism, and the left top plate 47 and the right top plate 4a retract towards the middle and overlap above the antenna 2. The internal electro-magnet 61 provides magnetic attraction to the left top plate 47 and the right top plate 4a.

[0066] Water-retaining eaves are connected to the upper right end of the left top plate 47 and the middle left end of the right top plate 4a. The water-retaining eaves are plate-shaped structures with a thickness less than that of the left top plate 47 or the right top plate 4a. A sealing strip 4b is installed on the water-retaining eaves of the right top plate 4a. When the vehicle-mounted antenna cabin is closed, the water-retaining eaves of the left top plate 47 overlaps the sealing strip 4b.

[0067] When the vehicle-mounted antenna container is deployed, the left top panel 47 is deployed first, followed by the right top panel 4a; when the antenna 2 is retracted, the right top panel 4a is retracted first, followed by the left top panel 47.

[0068] The right motor 54 drives the right inner support rod 55 to rotate to the right along the right motor 54, causing the right top plate 4a, the right moving plate 43, and the right outer support rod 48 to flip outward. The included angle between the right top plate 4a and the right moving plate 43 decreases until the right outer support rod 48 rotates 180° and sticks to the outer wall of the right fixed plate 33. After the right moving plate 43 and the right top plate 4a are folded, they stand on the outside of the right outer support rod 48 in sequence.

[0069] The outer wall of the front movable plate 42 is located above the inner wall of the front fixed plate 32. When the vehicle-mounted antenna cabin is deployed, the front electric push rod 58 pulls the front movable plate 42 down along the inner wall of the front fixed plate 32 until the front movable plate 42 is completely lower than the front fixed plate 32. The front slide rail 57 guides the downward pull, and the front electric push rod 58 locks the position of the front movable plate 42. When the vehicle-mounted antenna cabin is retracted, the front electric push rod 58 pushes the front movable plate 42 up along the inner wall of the front fixed plate 32 until the bottom of the front movable plate 42 is higher than the top of the front fixed plate 32. The front electric push rod 58 locks the position of the front movable plate 42.

[0070] The outer wall of the rear movable plate 44 is located above the inner wall of the rear fixed plate 34. When the vehicle-mounted antenna container is deployed, the rear electric push rod 5a pulls the rear movable plate 44 down along the inner wall of the rear fixed plate 34 until the rear movable plate 44 is completely lower than the rear fixed plate 34. The rear slide rail 59 guides the pull down, and the rear electric push rod 5a locks the position of the rear fixed plate 34. When the antenna 2 is retracted, the rear electric push rod 5a pushes the rear movable plate 44 up along the inner wall of the rear fixed plate 34 until the section of the rear movable plate 44 is located at the upper end of the rear fixed plate 34. The rear electric push rod 5a locks the position of the rear fixed plate 34.

[0071] Sealing strips are installed on the top and both sides of the front fixing plate 32 and the right fixing plate 33;

[0072] The main body of the left outer support rod 45 and the right outer support rod 48 is a straight rod, and the connection with the left movable plate 41 and the right movable plate 43 is provided with an elbow connection. There are two of each of the following: left outer support rod 45, left hinge seat 46, right outer support rod 48, right hinge seat 49, left motor 51, left inner support rod 52, left hinge seat 53, right motor 54, right inner support rod 55, and right hinge seat 56, which are located at the front and rear ends respectively.

[0073] The left inner support rod 52 and the right inner support rod 55 can be arc-shaped support rods, broken line rods (the included angle must be obtuse), or they can be made up of multiple rod segments connected together.

[0074] like Figure 1 As shown, with the hatch closed, the left movable plate 41, the front movable plate 42, the right movable plate 43, the rear movable plate 44, the left top plate 47, and the right top plate 4a are closed to form a normal container configuration.

[0075] like Figure 2 As shown, with the hatch open, the left movable panel 41 and the right movable panel 43 rotate 180 degrees, the left top panel 47 and the right top panel 4a flip 90 degrees, and are folded side by side and stored outside the container. The front movable panel 42 and the rear movable panel 44 are lowered to below the height of the container after the hatch is opened. Figure 8 , 10 As shown.

[0076] like Figure 3 The diagram shown is a schematic of a hatch opening process in this embodiment.

[0077] like Figure 7 As shown, a left hinge seat 53 is installed at the front and rear of the inner side of the left top plate 47, which is connected to the left motor 51 via the left inner support rod 52. The left motor 51 is fixed to the side wall of the container and directly drives the left inner support rod 52 to rotate. The left top plate 47 and the left movable plate 41 are hinged by multiple hinges, so that the included angle between the left top plate 47 and the left movable plate 41 is variable. A pair of left outer support rods 45 are fixedly installed at both ends of the outer wall of the left movable plate 41, and the other end of the left outer support rod 45 is hinged to the left hinge seat 46 on the outer wall of the container. The left top plate 47, the left movable plate 41, the left outer support rod 45, and the left inner support rod 52 form a four-bar linkage mechanism. The motor 8 drives the left inner support rod 52 to rotate actively, causing the left top plate 47 and the left movable plate 41 to fold and flip outward together. The right side is the same as the left.

[0078] A pair of linear guide rails 57 and 59 are installed at both ends of the front and rear bulkheads of the container, and their matching sliders are installed on both sides of the front moving plate 42 and the rear moving plate 44 to serve as guides. The main body of the electric push rods 58 and 5a is fixedly connected to the middle of the bulkhead at the front and rear. The output end of the push rod is connected to the front moving plate 42 and the rear moving plate 44 by a ball joint, which provides power output without excessive constraint.

[0079] An internal electrically controlled permanent magnet 61 is installed at the top center of the front movable plate 42 and the rear movable plate 44, and an external electrically controlled permanent magnet 63 is installed at a specific position on the outer wall of the container to lock the mechanism. Embedded irons 62 are set at appropriate positions on the inner and outer ends of the left top plate 47 and the right top plate 4a to enhance the magnetic effect. When the hatch is opened, the external embedded irons 62 of the top plate are attracted to the external electrically controlled permanent magnets 63, and when the hatch is closed, the internal embedded irons of the top plate are attracted to the internal electrically controlled permanent magnets 61. The internal electrically controlled permanent magnets 61 and the external electrically controlled permanent magnets 63 are controlled by electrical signals to determine whether they are magnetic, and are equipped with a power supply so that they retain their magnetism even after the power is cut off.

[0080] like Figure 5 As shown, a water-retaining sill and a sealing strip 4b are added between the junction of the left top plate 47 and the right top plate 4a, so that when the hatch is closed, the water-retaining sill 22 of the left top plate 47 presses against the sealing strip 3 of the water-retaining sill 22 of the right top plate 4a. In addition, sealing strips are also installed on the top and sides of the front hatch 3 and the rear hatch 4 to improve the hatch's sealing performance.

[0081] like Figure 3 As shown, when the hatch is opened, the programmed actions are as follows: first, the magnetism of the inner electromagnet 61 and the outer electromagnet 63 is eliminated, and the mechanism is successfully unlocked. Then, the left top plate 47 flips at a certain angle, and the right top plate 4a begins to flip accordingly. The left top plate 47, the right top plate 4a, the left moving plate 41, and the right moving plate 43 flip in sequence to their positions. The left motor 51 drives the left inner support rod 52 to rotate, and the right motor 54 drives the right inner support rod 55 to rotate, causing the left top plate 47, the right top plate 4a, the left moving plate 41, and the right moving plate 43 to flip outward together, so that the left top plate 47 and the right top plate 4a flip 90 degrees, and the left moving plate 41 and the right moving plate 43 rotate 180 degrees, and finally fold side by side and store them on the outer wall of the container. Then, the front and rear electric push rods 58 and 5a operate synchronously, and the front moving plate 42 and 44 descend vertically to the set position along the straight front slide rail 57 and rear slide rail 59. The inner electric permanent magnet 61 and the outer electric permanent magnet 63 regain their magnetism, and the hatch is locked in the open state.

[0082] Similarly, when the hatch is closed, the inner electrically controlled permanent magnet 61 and the outer electrically controlled permanent magnet 63 are demagnetized and unlocked first. The front electric push rod 58 and the rear electric push rod 5a operate, and the front moving plate 42 and the rear moving plate 44 rise to their set positions. The left top plate 47, the right top plate 4a, the left moving plate 41, and the right moving plate 43 flip sequentially, with the right top plate 4a flipping into place before the left top plate 47. Figure 5 As shown, the waterproof eaves of the left top plate 47 press on the sealing strip 4b of the waterproof eaves of the right top plate, the inner electro-magnet 61 and the outer electro-magnet 63 regain their magnetism, and the hatch is locked in the closed state.

[0083] This embodiment is applied in a vehicle-mounted antenna container with a large aperture surface width of 3.8m. The height of the container is 3.2m when closed and 2.8m when opened, which can ensure that the large aperture antenna can rotate 360° without interference.

Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
