Description

Technical Field

[0001] This invention belongs to the field of vehicle-mounted launch platform container technology, and specifically discloses a vehicle-mounted launch platform container and a control method. Background Technology

[0002] With the development of modern industry and the continuous improvement of special equipment, vehicle-mounted launch platforms play a crucial role in the transportation, delivery, and launch of special equipment. To meet the requirement that certain launch devices need to form a specific angle with the ground during operation, special containers are usually designed with a combination of a top flip-up door and a rear fully open downward-folding door, so that the top and rear of the container can be fully open without obstruction during launch.

[0003] However, existing vehicle-mounted shelters have significant deficiencies in structural stability, operational adaptability, and closure reliability. Firstly, in terms of structural design, most existing shelters employ simple frame or composite panel structures. Because the rear must be fully openable, they often lack a fixed upper rear crossbeam, directly compromising the original "cage-like" stable structure. This structural defect prevents the effective transfer of top forces to the sides, rear, and floor, making the shelter's maximum displacement deformation and stress load easily exceed tolerances under extreme conditions, posing a risk of structural failure.

[0004] Secondly, in actual operating environments, special vehicles often operate under harsh conditions, and the severe vibrations, impact loads, and jet streams generated during the operation of the launch equipment exert complex stresses on the container. Due to the lack of effective constraint and connection mechanisms, the relative positions of the rear ends of the left and right side panels of the container are prone to uncontrollable displacement and deformation. Furthermore, during the closure process, existing top-hinged doors rely heavily on gravity or simple assistance, lacking a real-time confirmation and feedback adjustment mechanism for the final closing attitude. Once the container deforms due to stress, it will directly lead to a loose connection between the top-hinged door and the side panels, causing a failure in the container's watertightness and seriously affecting the safety of the internal equipment.

[0005] Furthermore, the locking mechanism of the existing rear-hinged door of the modular container is usually fixed to the upper part of the left and right side panels, making it extremely sensitive to deformation of the rear end of the container. When deformation of the rear end causes the original locking position to shift, the rear-hinged door will face problems such as difficulty in closing, inability of the locking mechanism to reset, and may even open abnormally during vehicle movement, leading to serious traffic or equipment accidents.

[0006] Finally, most current modular shelters employ purely mechanical connections and locking structures, lacking the ability to continuously monitor deformation in areas where the shelter is repeatedly opened, and also unable to provide early warnings of deformation trends. Although a very small number of solutions use manually installed reinforcing beams, their installation is cumbersome and time-consuming, and cannot adapt to the dynamic deformation calibration requirements caused by environmental changes, making it difficult to meet the development trend of modern special modular shelters towards intelligence, rapid response, and high-precision control. Summary of the Invention

[0007] The technical problem this invention aims to solve is that existing vehicle-mounted launch container structures with a fully open rear design suffer from defects such as the lack of a fixed upper rear crossbeam, which damages the original "cage-like" stabilizing structure. This makes the container prone to uncontrollable deformation under harsh driving conditions and impact loads generated by the launch device operation. Furthermore, existing opening mechanisms cannot perform real-time confirmation and calibration of the closed attitude, which can easily lead to watertight failure and accidental opening. This invention provides a design and control method for a vehicle-mounted launch platform container that features real-time monitoring, self-calibration of the closed attitude, and dynamic restoration of the "cage-like" stabilizing structure.

[0008] To address the aforementioned technical problems, this invention provides a vehicle-mounted launch platform cabin, comprising a base with a left side panel and a right side panel connected to it. A rotatable, openable top-hinged door is located on the upper part of the base. A movable rear crossbeam is located within the rear area of ​​the top-hinged door. The movable rear crossbeam includes a main crossbeam and a first locking assembly and a second clamping assembly located at both ends of the main crossbeam. V-shaped slots are respectively provided on the inner sides of the left and right side panels. When the top-hinged door is closed, the first locking assembly and the second clamping assembly, under the action of a driving mechanism, are displaced along the axial direction of the main crossbeam to cooperate in clamping and fixing the V-shaped slots from different directions, thus forming a cage-like stable structure for the cabin.

[0009] Furthermore, the first locking assembly includes two internal motors symmetrically arranged inside the main crossbeam; each internal motor is fixedly connected to a T-shaped tie rod, the T-shaped tie rod including a first shaft segment and a second shaft segment arranged coaxially, and the first shaft segment and the second shaft segment can rotate relatively independently; the outer end face of the second shaft segment is provided with an external thread, and the end of the main crossbeam is provided with an internal thread that mates with it; when the internal motor works and drives the second shaft segment to rotate, the rotational motion is converted into the movement of the T-shaped tie rod as a whole along the axial direction of the main crossbeam through the threaded engagement, so as to realize the insertion or disengagement of the first shaft segment into or out of the V-shaped slot. The two internal motors rotate in opposite directions when working to cancel out the rotational inertia they generate.

[0010] Furthermore, the second clamping assembly includes: a hollow rotary motor connected to the outside of the main crossbeam and an annular push rod sleeved at the end of the main crossbeam; the outer wall of the main crossbeam is provided with external threads, and the hollow rotary motor is fixedly connected to an internally threaded push rod that engages with the external threads; the hollow rotary motor drives the internally threaded push rod to rotate, thereby realizing the axial movement of the annular push rod to clamp the V-shaped slot end face, which engages with the first shaft section of the T-shaped pull rod to complete the clamping. A pre-tensioning spring is provided between the annular push rod and the internally threaded push rod, and the front end of the annular push rod is provided with an elastic pre-compression annular support sleeve to provide elastic clamping force and reset capability.

[0011] Furthermore, a monitoring and auxiliary switch integrated machine is installed at the rear upper end of the left and right side panels respectively, and wedge-shaped guide blocks are respectively provided on both sides of the rear of the top flip door; the monitoring and auxiliary switch integrated machine is equipped with a power gear auxiliary mechanism, which is used to mesh with the embedded rack on the wedge-shaped guide block to realize the auxiliary closing posture calibration or auxiliary opening of the top flip door.

[0012] Furthermore, it also includes a real-time offset monitoring system, which includes an infrared displacement sensor receiver installed on the side panel and an infrared displacement sensor transmitter installed inside the fully opening downward-folding tailgate at the rear of the base, for real-time monitoring of the relative offset between the tailgate and the side panel.

[0013] The present invention also provides a control method for the above-mentioned modular shelter, comprising the following steps: 1) Opening stage: unlocking and opening the tilting tail door; controlling the first locking component and the second clamping component of the movable rear crossbeam to move in opposite directions, releasing the clamping of the V-shaped slot; monitoring the action of the auxiliary switch integrated machine, and after the top tilting door is pushed open by a certain angle, it is fully opened by the structural cylinder. 2) Closing stage: the top tilting door falls, and the monitoring auxiliary switch integrated machine pulls the top tilting door to the closed position through the gear and rack structure; the tilting tail door closes, the infrared displacement sensor monitors the tail door offset and guides the controller to perform automatic calibration; after calibration, the T-shaped pull rod of the first locking component is controlled to extend into the V-shaped slot, and the second clamping component is axially clamped to complete the clamping and locking, and the modular shelter restores its cage-like stable structure. 3) Early warning control: the main controller compares the measured offset with the preset safety value. If the offset exceeds the preset safety value, an early warning signal is issued and the action is stopped; the main controller also records and analyzes the changes of multiple consecutive sets of offset values ​​to assess and predict the deformation trend of the modular shelter structure.

[0014] The beneficial effects of this invention are as follows: First, by adding a movable rear crossbeam to the top flip-up door and cooperating with the V-shaped slot design on the side panels, this invention fundamentally solves the structural stiffness fracture problem caused by the lack of a fixed rear crossbeam in fully openable shelters. In the closed state, the movable rear crossbeam, through the coordinated action of the first locking component and the second clamping component, achieves deep locking and bidirectional clamping of the V-shaped slots on the side panels. This design reshapes the "cage-like" stable structure of the shelter, completes the force transmission path, and enables the shelter to maintain extremely high overall stability and torsional resistance even when facing harsh operating conditions or severe impact loads generated by the launch device, effectively avoiding the risk of structural failure.

[0015] Secondly, this invention achieves a significant breakthrough in multi-dimensional precision calibration and operational stability. Through the mechanical cooperation of the T-shaped tie rod and the wedge-shaped guide block, the system can automatically correct the accuracy impact in the X and Z directions under the container coordinate system, while the integrated monitoring and auxiliary switch unit compensates for the closure depth of the container in the Y direction in real time through the power closed loop of the gear and rack. This multi-dimensional calibration mechanism ensures that the container can achieve a perfectly closed posture under various complex stress environments, completely solving the watertightness failure problem caused by deformation in traditional containers. At the same time, the motor inside the moving crossbeam adopts a reverse rotation design logic, which cleverly cancels the rotational inertia during the mechanism's operation at the physical level, significantly improving the smoothness and service life of the precision transmission components.

[0016] Furthermore, the unique "elastic shock-resistant" mechanism of this invention greatly enhances the equipment's survivability redundancy. The specially designed pre-tension spring and elastic support sleeve in the second clamping assembly provide the locking mechanism with a certain degree of flexible buffering capability. During special operations, instantaneous high-pressure jet airflow or huge recoil impacts may occur, and the vehicle's cabin structure is prone to twisting and other structural deformations under harsh industrial driving conditions. This elastic structure can actively absorb and filter energy, playing a significant role in buffering and shock absorption, preventing the locking mechanism from hardly breaking or abnormally opening due to jamming caused by instantaneous overload deformation of the side panels.

[0017] Finally, this invention represents a leap from traditional mechanical structures to an intelligent and precise platform. A digital monitoring system, comprised of infrared displacement sensors and a central controller, enables millimeter-level online monitoring of deformation in repeatedly opened areas of the cabin. By establishing a three-tiered "green, yellow, and red" early warning mechanism, the system can not only assess the current closure safety of the cabin in real time but also perform in-depth trend analysis by recording and exporting multiple sets of historical offset values, predicting the plastic deformation trend and lifespan of the cabin structure. This fully automated closed-loop control and failure early warning capability significantly enhances the inherent safety boundary of the cabin and provides detailed data support for subsequent structural optimization design, fully meeting the design evolution requirements of modern special-purpose cabins for intelligence, unmanned operation, and precision.

Detailed Implementation

[0021] The technical solutions (including preferred technical solutions) of the present invention will be further described in detail below with reference to the accompanying drawings and by way of listing some optional embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0022] like Figure 1-17 As shown, this invention discloses a design and control method for a vehicle-mounted launch platform container. The technical solution includes an L-shaped base, on which a top flip-up door 001, a left side panel 002, a right side panel 003, and a fully opening downward-folding tailgate 004 are connected. The left side panel 002 and right side panel 003 are connected to both sides of the base. A rotatable top flip-up door 001 is provided at the upper part of the base, and a fully opening downward-folding tailgate 004 is provided at the end of the base. A movable rear crossbeam 005 and a wedge-shaped guide block 010 are provided on the fully opening downward-folding tailgate 004. 010 is installed on the side of the top flip door 001. The left side panel 002 and the right side panel 003 are equipped with V-shaped slots 006, infrared displacement sensor transmitters 007 and 008, integrated monitoring and auxiliary switch 009, tailgate electro / hydraulic structure cylinder 011, transmitter platform electro / hydraulic structure cylinder 012, linkage rod 013, movable rear crossbeam 005 and V-shaped slots 006 are arranged in corresponding positions, and wedge-shaped guide blocks 010 and infrared displacement sensor receivers 008 and integrated monitoring and auxiliary switch 009 are arranged in corresponding positions.

[0023] The vehicle-mounted container, designed to meet the actual needs of the launch platform, requires sufficient space for launch operations. Therefore, the top of the container is designed as a forward-flipping top door 001, and the rear is designed as a fully opening downward-folding door 004. When the launch device is in operational mode, it must be able to open both the top flipping door 001 and the fully opening downward-folding rear door 004 simultaneously. At this time, the entire top and rear of the container will have an unobstructed, fully open structure. In other states, the fully opening downward-folding rear door 004 must be able to open independently.

[0024] The movable rear crossbeam 005 is a key component for adjusting and calibrating the vehicle-mounted launch platform cabin. Based on the cabin structure and mechanical analysis, the movable rear crossbeam 005 should be arranged as far back as possible in the cabin. Considering the convenience of installation and maintenance of the movable rear crossbeam 005, it is installed in a way that connects to the beam system in the rear area inside the top flip door 001, and can be opened and closed together with the top cover.

[0025] The movable rear crossbeam 005 is equipped with a hollow main crossbeam 1, a T-shaped tie rod 2, a hollow rotary motor 3, an internal motor 4, and a ring push rod 5. The ring push rod 5 is composed of three parts: a ring support sleeve 6, a pre-tightening spring 7, and a push rod with internal threads 8.

[0026] V-shaped slot 006 includes a base block installed on the left side panel 002 and the right side panel 003. The end face of the base block has a groove for accommodating the T-shaped tie rod 2 on the movable rear crossbeam 005 and a hole for avoiding the main crossbeam 1.

[0027] The T-shaped pull rod 2 and the ring push rod 5 work together to clamp the V-shaped slot 006.

[0028] In the movable rear crossbeam 005, the main crossbeam 1 preferably has a circular cross-section. This is because a circular cross-section distributes stress more evenly, better withstands compression and tension, and possesses higher strength and stability to handle torsional and bending conditions. The beam system uses Q500E seamless steel pipe. Both the inner and outer sides of the circular ends of the main crossbeam 1 are designed with threaded structures to facilitate the movable structure.

[0029] The movable rear crossbeam is further designed with T-shaped tie rods 2 at both ends. As a key component of the connecting structure, these rods are made of 40Cr alloy steel with good mechanical properties and sufficient strength. The T-shaped tie rod 2 includes a first shaft segment and a second shaft segment arranged coaxially. The first and second shaft segments can rotate relatively independently. The outer end face of the second shaft segment is provided with external threads. The second shaft segment is fixedly connected to the rotating shaft of the motor 4. The motor 4 is axially displaceable and is located inside the main crossbeam 1. The second shaft segment of the T-shaped tie rod 2 is fixedly connected to the motor 4. The motor 4 drives the second shaft segment of the T-shaped tie rod 2 to rotate. The external thread of the second shaft segment of the T-shaped tie rod 2 is threadedly engaged with the internal thread at the end of the main crossbeam 1. When the motor 4 located inside the main crossbeam 1 works, it drives the second shaft segment of the T-shaped tie rod 2 to rotate. The threaded engagement between the second shaft segment of the T-shaped tie rod 2 and the main crossbeam 1 converts the rotational motion of the motor into the axial forward and backward movement of the T-shaped tie rod 2 and the motor 4. The screw drive features high load-bearing capacity, continuous and stable operation, and high transmission accuracy, which perfectly meets the design requirements of the movable rear crossbeam 005. Because the T-shaped tie rods 2 at both ends of the movable rear crossbeam 005 drive the internal motors 4 in a symmetrical arrangement, and the internal motors 4 rotate in opposite directions during operation, the rotational inertia generated by the two internal motors 4 can be effectively counteracted.

[0030] A hollow rotary motor 3, which can be displaced along its axis, is connected to the outer side of the main crossbeam 1. An internal thread push rod 8 is connected to the external thread of the main crossbeam 1. The internal thread push rod 8 and the hollow rotary motor 3 are fixedly connected. The hollow rotary motor 3 drives the internal thread push rod 8 to rotate around its central axis. The outer end of the internal thread push rod 8 is slidably fitted with an annular push rod 5, which can be displaced around its axial direction. A preload spring 7 is provided between the annular push rod 5 and the internal thread push rod 8. The annular push rod 5 moves axially back and forth through the structure with the internal thread push rod 8 and is driven by the external hollow rotary motor 3. The front end of the annular push rod 5 is designed with an elastic preload annular support sleeve 6 mechanism with a preload spring 7 structure, which can provide elastic clamping force and reset capability within a certain working stroke.

[0031] The upper rear part of the inner side of the left side panel 002 and the right side panel 003 is designed with a reinforced boss structure for installing the V-shaped slot 006 structure respectively.

[0032] In the further movable rear crossbeam 005, the T-shaped tie rod 2 and the ring push rod 5 together form the core of the movable rear crossbeam 005 adjustment and locking mechanism. This mechanism, combined with the V-shaped slots 006 installed on the left and right side panels 002 and 003, adjusts and locks the connection. Currently, the mainstream connection mechanisms are bolted connections and friction connections. Bolted connections require high precision, and the screw structure carries the risk of thread deformation leading to structural failure under high loads. Friction connections have relatively lower precision requirements and offer significant advantages in high load resistance and impact resistance. Therefore, this design utilizes the classic friction connection structure to address the precision issues in the X, Y, and Z directions at the movable connection point. The T-shaped tie rod 2, in conjunction with the V-shaped slot 006, effectively resolves the precision impact from the X and Z directions of the cabin during closure. Furthermore, by changing the spacing at the connection point of the movable rear crossbeam 005, the relative precision issues between the left and right side panels 002 and 003 of the cabin can be effectively resolved.

[0033] Infrared displacement sensor receivers 008 are installed in the upper outer areas of the left side panel 002 and the right side panel 003, respectively. Infrared displacement sensor transmitters 007 are installed in the upper left and right sides of the fully opening, downward-folding tailgate 004. When the fully opening, downward-folding tailgate 004 is closed, the infrared displacement sensor receivers 008 enter the working area, and the fully opening, downward-folding tailgate 004 stops closing. At this time, the relative offset between the fully opening, downward-folding tailgate 004 and the left side panel 002 and the right side panel 003 can be calculated using the signals from the infrared displacement sensor transmitters 007 and the infrared displacement sensor receivers 008, which is a key prerequisite for meeting the real-time left-right displacement calibration capability of the stern of the container.

[0034] Monitoring and auxiliary switch integrated unit 009 is installed at the upper rear of the left side panel 002 and the right side panel 003 respectively. The monitoring and auxiliary switch integrated unit 009 can monitor the closed position status of the top flip door 001 and make corresponding solutions based on different closed position statuses. This includes activating the auxiliary closing function when the top flip door 001 is not fully closed, and activating the auxiliary opening function when the top flip door 001 needs to be opened.

[0035] The further monitoring auxiliary switch integrated unit 009 is equipped with a guide base 9, a power gear auxiliary mechanism 10, and a relative position transmitter / receiver 11. The power gear auxiliary mechanism 10 is installed in the guide base 9 and moves linearly back and forth via a guide rail structure. The linear motion power of the guide base 9 and the power gear auxiliary mechanism 10 comes from an internally arranged gear and rack mechanism. In the non-working state, the left and right power gear auxiliary mechanisms 10 are guided back to the center position of the container via the left and right guide bases 9 respectively, avoiding direct contact between the gear structure at the end of the power gear auxiliary mechanism 10 and other structures such as the wedge-shaped guide block 010; moreover, the front gear structure of the power gear auxiliary mechanism 10 has a clutch function and can move freely in the non-working state. These two structural designs effectively prevent the risk of damage to the mechanism due to accidental impacts or rolling.

[0036] Each of the left and right inner sides of the rear of the top flip door 001 is provided with a wedge-shaped guide block 010. The wedge-shaped guide block 010 is provided with an embedded rack 12 and a relative position marking plate 13 structure.

[0037] When the top flip door 001 is closed, the wedge-shaped structure of the front section of the wedge-shaped guide block 010 arranged on its left and right inner sides, together with the upper rear guide profile beam 14 of the left side panel 002 and the right side panel 003, can quickly position and quickly gather the left side panel 002 and the right side panel 003.

[0038] When the top flip door 001 finishes its descent, the relative position transmitter / receiver 11 in the monitoring auxiliary switch integrated unit 009 begins operation. The receiver / receiver 11 transmits a signal to the relative position marker plate 13 in the wedge-shaped guide block 010 and reflects the signal. By converting the signal data, the distance and relative position information between the monitoring auxiliary switch integrated unit 009 and the wedge-shaped guide block 010 can be obtained. Because the wedge-shaped guide block 010 is rigidly installed inside the top flip door 001, this relative position information reflects the closing status of the top flip door 001, which is a crucial prerequisite for achieving the closing posture position calibration capability of the top flip door 001.

[0039] When the top flip door 001 finishes its descent, the relative position transmitter / receiver 11 in the monitoring auxiliary switch integrated unit 009 completes the first position signal collection. The signal is converted to determine the relative position between the left and right wedge-shaped guide blocks 010 and the left and right monitoring auxiliary switch integrated units 009. The power gear auxiliary mechanism 10 in the monitoring auxiliary switch integrated unit 009, guided by the guide base 9, begins to move according to the converted relative position information. The gear on the power gear auxiliary mechanism 10 engages with the embedded rack 12 on the wedge-shaped guide blocks 010 to form a complete gear and rack mechanism. Based on the position signal collected by the relative position transmitter / receiver 11 in the monitoring auxiliary switch integrated unit 009, the gear and rack mechanism in the monitoring auxiliary switch integrated unit 009 and the left and right wedge-shaped guide blocks 010 can be activated for position correction. The correction effect is judged based on real-time monitoring feedback data until the top flip door 001 closes completely.

[0040] The specific control method when the mobile shelter is in operation is as follows: When the launch platform needs to enter operational status, the upper locking mechanism of the fully opening downward-folding tail door 004 unlocks, and the fully opening downward-folding tail door 004 structure is opened through the tail door electro-hydraulic structure cylinder 011 located at the rear of the cabin. This completes the opening operation of the fully opening downward-folding tail door 004.

[0041] Before the top tilting door 001 of the modular shelter needs to be opened, the movable rear crossbeam 005 structure must be unlocked, more specifically, the unlocking process of the T-shaped tie rod 2 and the ring push rod 5 structure. The specific process is as follows: During the unlocking process of the two-end annular push rods 5, the structure of the two-end annular push rods 5 is driven by an external hollow rotary motor 3 to move axially and simultaneously towards the center of the cabin. When the amount of movement towards the center of the cabin is greater than the amount of movement towards the outside of the cabin when closed, the elastic pre-compression mechanism of the annular push rod 5 at the front end of the push rod fails, and the thrust of the two ends of the movable rear crossbeam 005 structure and the V-shaped slot 006 structure on the left side panel 002 and the right side panel 003 disappears, completing the unlocking of the annular push rod 5 structure.

[0042] Unlocking of the T-shaped tie rods 2 at both ends. The T-shaped tie rods 2 at both ends also move axially via an internal motor 4 with a helical drive, moving simultaneously outwards from the container. When they reach a certain displacement, the tension between the T-shaped tie rods 2 and the V-shaped slots 006 on the left and right side panels 002 and 003 disappears, completing the unlocking of the T-shaped tie rods 2. The displacement is designed to be greater than the displacement when closed, ensuring that the T-shaped tie rods 2 can be completely unlocked from the V-shaped slots 006.

[0043] After the movable rear crossbeam 005 structure of the top tilting door 001 of the shelter is unlocked, the shelter enters the auxiliary opening stage of the top tilting door 001. More specifically, the left and right monitoring auxiliary switch integrated machine 009 and the left and right wedge guide blocks 010 work together to complete the auxiliary opening of the top tilting door 001. The specific process is as follows: After the movable rear crossbeam 005 structure in the top tilting door 001 of the shelter completes the unlocking process, a command signal is issued, and the monitoring and auxiliary switch integrated unit 009 installed at the upper rear of the left side panel 002 and the right side panel 003 begins to work. First, the position transmitter and receiver 11 in the monitoring and auxiliary switch integrated unit 009 transmits a signal to the relative position marker plate 13 in the wedge-shaped guide block 010 and reflects the signal. By converting the signal data, the distance and relative position information between the monitoring and auxiliary switch integrated unit 009 and the wedge-shaped guide block 010 can be obtained at this time. In the monitoring and auxiliary switch integrated unit 009, the power gear auxiliary mechanism 10 is guided by the guide base 9 and begins to move towards the outside of the cabin according to the converted relative position information. After the gear on the power gear auxiliary mechanism 10 and the embedded rack 12 on the wedge guide block 010 are combined to form a complete gear rack mechanism, a command signal is issued and the gear rack mechanism starts to work, providing relative displacement to the upper part of the cabin. This allows the wedge guide blocks 010 at both ends of the inner side of the top flip door 001 to be smoothly disengaged from the upper guide profile beam 14 behind the left side panel 002 and the right side panel 003. The top flip door 001 drives the launch platform through the electro-hydraulic structure cylinder 012 of the launch platform. The linkage linkage rod 013 structure at both ends of the launch platform drives the linkage opening process, completing the cabin opening working state.

[0044] The specific control method when the mobile shelter is in the closed working state is as follows: When the launch platform completes its working state, the top flip door 001 drives the launch platform through the electro-hydraulic structure cylinder 012, and the linkage rods 013 at both ends of the launch platform drive the linkage to close, realizing the falling and closing process. When the top flip door 001 reaches the closing state, the wedge-shaped guide blocks 010 at both ends of the inner side of the top flip door 001 contact the upper guide profile beam 14 of the left side panel 002 and the right side panel 003. Because both sets of mechanisms are designed with wedge-shaped guide structures, the top flip door 001 can quickly position and quickly gather the left side panel 002 and the right side panel 003, completing the pre-closing action of the top flip door 001.

[0045] When the top flip door 001 reaches the closing position, the monitoring auxiliary switch integrated unit 009, installed at the upper rear of the left side panel 002 and the right side panel 003, begins to operate. First, the position transmitter / receiver 11 in the monitoring auxiliary switch integrated unit 009 transmits a signal to the relative position marker plate 13 in the wedge-shaped guide block 010 and reflects the signal in real time. Based on the real-time monitoring feedback data, it determines whether the top flip door 001 is fully closed. If it determines that the top flip door 001 is fully closed, the monitoring auxiliary switch integrated unit 009 does not proceed to the next step; if it determines that the top flip door 001 is not fully closed, the monitoring auxiliary switch integrated unit 009 proceeds to the next step. The specific process is as follows: By converting the relative position signal in the signal data, the distance and position information between the monitoring auxiliary switch integrated unit 009 and the wedge-shaped guide block 010 can be obtained. The power gear auxiliary mechanism 10 in the monitoring auxiliary switch integrated unit 009, guided by the guide base 9, begins to move outwards from the cabin based on the converted relative position information. Once the gear on the power gear auxiliary mechanism 10 and the embedded rack 12 on the wedge-shaped guide block 010 combine to form a complete gear and rack mechanism, a command signal is issued, and the gear and rack mechanism begins to work, providing relative displacement to the lower part of the cabin. At this time, the position transmitter and receiver 11 in the monitoring auxiliary switch integrated unit 009 works in real time to convert the relative position information until the preset value for complete closure is reached, at which point a signal is issued, and the power gear auxiliary mechanism 10 in the monitoring auxiliary switch integrated unit 009 stops operating. At this time, the top flip door 001 closes completely.

[0046] When the top flip door 001 is closed, the power gear auxiliary mechanism 10 in the auxiliary switch unit 009 is in a rearward position. The entire structure of the auxiliary switch unit 009 does not directly contact the top flip door 001 or the wedge-shaped guide blocks 010 at both ends of the inner side of the top flip door 001, effectively preventing the impact force generated when the top flip door 001 falls and closes from affecting the auxiliary switch unit 009 and causing it to malfunction or be damaged.

[0047] When the top tilting door 001 is closed, the monitoring and auxiliary switch integrated unit 009 transmits a signal to initiate the closing process of the fully open tilting tail door 004. The fully open tilting tail door 004 structure achieves the closing process through the tail door electro / hydraulic structure cylinder 011 located at the rear of the cabin. When the closed state reaches the design control point, the closing process stops when the infrared displacement sensor transmitters 007 inside the upper left and right sides of the fully open tilting tail door 004 structure and the infrared displacement sensor receivers 008 inside the upper outer rear areas of the left side panel 002 and the right side panel 003 enter the working range. At the same time, the T-shaped tie rods 2 at both ends of the movable rear crossbeam 005 in the top tilting door 001 have fallen into the V-shaped slots 006 on the left side panel 002 and the right side panel 003. At this time, the calibration and locking process during the closing process officially begins. The specific process is as follows: Real-time calibration and adjustment phase. When the closed state reaches the control point, the infrared displacement sensor transmitters 007 inside the upper left and right sides of the fully open downward-opening tailgate 004 structure, and the infrared displacement sensor receivers 008 inside the upper outer rear areas of the left side panel 002 and right side panel 003, generate specific offset values ​​based on the relative offset positions and send them to the main controller. The main controller sends drive signals to the internal motors 4 of the movable rear crossbeam 005 based on the left and right offset values ​​to achieve the tightening of the T-shaped tie rods 2 at both ends. At this time, the infrared displacement sensors continue to work, sending the left and right offset values ​​to the main controller in real time. The displacement calibration work stops when the left and right offsets are each <2mm. Because the locking mechanism of the fully open downward-opening tailgate 004 structure is located at the upper rear of the left side panel 002 and right side panel 003 after the structure is closed, the locking mechanism of the fully open downward-opening tailgate 004 structure can only be successfully activated and complete the locking function when the inner distance between the upper ends of the left side panel 002 and right side panel 003 meets the allowable tolerance of the locking mechanism. Meanwhile, the preset calibration stop minimum left and right offset can be adjusted according to the locking mechanism tolerance and actual site requirements. When the tightening operation of the T-shaped tie rods 2 at both ends begins, the main controller will send a signal to the monitoring and auxiliary switch integrated unit 009. The power gear auxiliary mechanism 10 in the monitoring and auxiliary switch integrated unit 009 is guided by the guide base 9 to move into the cabin, away from the wedge-shaped guide block 010 structure, to avoid damage to the power gear auxiliary mechanism 10 in the monitoring and auxiliary switch integrated unit 009 due to the tightening operation of the T-shaped tie rods 2.

[0048] The ring push rod clamping stage. After the T-shaped tie rods 2 at both ends of the movable rear crossbeam 005 are tightened, the ring push rods 5 at both ends of the movable rear crossbeam 005 begin to work. The ring push rods 5 at both ends move axially through the external hollow rotary motor 3, and move towards the outside of the cabin. The main controller drives the external hollow rotary motor 3 according to the displacement of the left and right T-shaped tie rods 2 to achieve the elastic clamping action of the ring push rods 5. This completes the elastic clamping of the V-shaped slots 006 on the left side panel 002 and the right side panel 003. It can be understood that the T-shaped tie rods 2 and the ring push rods 5 clamp the V-shaped slots 006 from both sides under the action of the internal motor 4 and the rotary motor 3, respectively. One side of the ring push rods 5 is elastically loaded, and one side of the T-shaped tie rods 2 is rigidly loaded. The friction generated after the T-shaped tie rods 2 and the ring push rods 5 clamp the V-shaped slots 006 can ensure the closing of the top flip door 001.

[0049] The rear tailgate is fully closed. After the T-shaped tie rods 2 at both ends of the movable rear crossbeam 005 are tightened, the fully open downward-folding tailgate 004 continues to close. Since the calibration work has been completed at this time, the locking mechanism of the fully open downward-folding tailgate 004, the left side panel 002, and the upper rear of the right side panel 003 has reached the working tolerance range, and the locking reset procedure can be completed, thus ending the cabin closure process.

[0050] After the real-time calibration and adjustment phase is completed, the ring push rods 5 at both ends of the movable rear crossbeam 005 and the locking operation of the fully open downward-folding tailgate 004 start simultaneously, which can effectively shorten the total time of the closing process.

[0051] The working principle of the continuous monitoring and early warning function is as follows: After the pre-closing action of the top flip door 001 is completed, the monitoring auxiliary switch integrated unit 009, installed at the upper rear of the left side panel 002 and the right side panel 003, begins to operate. Based on the reflected signal, it converts the left and right closing positions of the top flip door 001. The main controller compares the data with the stored previous left and right closing positions. When the difference is less than a preset safety value, a green command is issued, and the monitoring auxiliary switch integrated unit 009 proceeds to the next step, ultimately completing the closing action of the top flip door 001. When the difference is close to but not greater than the preset safety value, the main controller issues a yellow warning signal, and the monitoring auxiliary switch integrated unit 009 continues to the next step. When the difference is greater than the preset safety value, the main controller issues a red warning signal, and the monitoring auxiliary switch integrated unit 009 stops the next step.

[0052] When the closing process of the fully opening downturn tailgate 004 begins and before entering the real-time calibration and adjustment stage, the infrared displacement sensor transmitters 007 located at the upper left and right sides of the fully opening downturn tailgate 004 structure, and the infrared displacement sensor receivers 008 located in the upper outer rear areas of the left side panel 002 and the right side panel 003, generate specific offset values ​​based on the relative offset positions and send them to the main controller. The main controller compares the data with the stored previous left and right closing positions. When the difference is less than a preset safety value, a green command is issued, and the real-time calibration and adjustment function continues to operate, ultimately completing the closing process of the fully opening downturn tailgate 004. When the difference is close to but not greater than the preset safety value, the main controller issues a yellow warning signal, and the real-time calibration and adjustment function continues to operate. When the difference is greater than the preset safety value, the main controller issues a red warning signal, and the real-time calibration and adjustment function stops operating in the next step.

[0053] During use, the shelter's opening mechanism or main structure may experience deformation or displacement due to harsh conditions, including vibrations, impact loads, and jet streams generated during launch equipment operation. Continuous monitoring capabilities can effectively and proactively warn of these risks. When the monitored offset difference approaches a preset safety value, the main controller issues a yellow warning signal, effectively prompting a timely inspection of the shelter's opening mechanism or main structure after this use to avoid risks such as mechanism failure due to deformation or displacement. Simultaneously, the main controller has the ability to record and export multiple recent offset values. By analyzing multiple consecutive offset values ​​over a period of time, the deformation trend of the shelter's opening mechanism or main structure can be determined, providing a reference for structural verification and subsequent design improvements. Large short-term offset values ​​may indicate mechanism damage, while continuous offsets may indicate structural reliability issues.
