This saves them the hassle of finding a hotel and the cost of staying there, while also allowing them to get closer to nature and enjoy the nighttime scenery.

[0003] Currently, sleeping pods are generally installed on the roof of cars. The car moves along with the sleeping pod while in motion. However, sleeping pods typically have a certain weight and pressure. When the car is moving, because the sleeping pod is on the roof, braking or acceleration will generate an inertial load on the vehicle. If the pressure or speed of the sleeping pod is too high, the rear of the car may slightly lift, causing instability.

[0018] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0019] Please see Figures 1-8 A rooftop sleeping pod pressure resistance testing device includes a simulated vehicle 1; a linear motor 2 for providing the motion state of the simulated vehicle 1; a testing component 3 for detecting the motion posture of the simulated vehicle in terms of weight and speed during the transportation of the sleeping pod 403; the testing component 3 includes a positioning device, a bidirectional free device, and a display device 307; the positioning device is connected to the simulated vehicle 1 for fixing it to the simulated vehicle 1; the bidirectional free device is used to provide the inertial rollover degree of freedom generated by the simulated vehicle 1 when moving forward or backward; the display device 307 is used to record the angular rollover generated by the motion simulation of the simulated vehicle 1 in real time; the positioning device is connected to the simulated vehicle 1, the bidirectional free device is connected to the positioning device, and the display device 307 is connected to the positioning device; and a weight-bearing component 4 for adjusting the load-bearing capacity of the simulated vehicle 1 during each cycle of testing.

[0020] In this embodiment, the positioning device includes a left frame 302 and a right frame 303. A left stop 311 is connected to the left side of the left frame 302. Semicircular sleeves 309 are connected to both the left frame 302 and the right frame 303. The left stop 311 and a locking rod 304 are rotatably connected to the two semicircular sleeves 309, respectively. The simulated vehicle 1 is located between the locking rod 304 and the left stop 311. When the simulated vehicle 1 moves, the linear movement of the simulated vehicle 1 is propelled by the abutment of the left stop 311 and the locking rod 304.

[0021] Furthermore, the bidirectional free device includes two supports 301 connected to the linear motor 2. Each support 301 has a semi-circular groove 306, within which a connecting shaft 308 is connected. The two connecting shafts 308 are respectively connected to the left frame 302 and the right frame 303. Both the left frame 302 and the right frame 303 are connected to semi-circular sleeves 309, each with a groove 3091. A long shaft 310 is connected within the groove 3091, and a middle rod 312 connects the two long shafts 310. Two display devices 307 are provided, one on the left frame 302 and the other on the right frame 303. This bidirectional free device enables the simulator 1 to perform dual detection of "forward" and "reverse" movements during reciprocating motion simulation, directly simulating forward movement and obstacle avoidance during reversing. This improves the simulation diversity of the simulator 1 and provides data reference for subsequent actual operation. Because, relatively speaking, the power output relies on the linear motor 2, and the power of the linear motor 2 is connected to the positioning device. The power of the linear motor 2 drives the positioning device to move, which in turn indirectly drives the motion simulation of the simulator 1.

[0022] Furthermore, the display device 307 includes a card holder 3074 with a slot for inserting a drawing board 3073. The card holder 3074 is mounted on the left side frame 302. A connecting rotating plate 3071 is fixedly connected to the long shaft 310. A pen 3072 is mounted on the connecting rotating plate 3071. The tip of the pen 3072 abuts against the drawing board 3073. When the simulator 1 moves and flips, it will control the pen 3072 to draw a trajectory on the drawing board 3073. When the linear motor 2 reaches a certain speed, it causes the simulator 1 to "flip over." At this time, the simulator 1 will rotate around the long shaft 310 on the left frame 302 as the center of rotation, and the tail will lift up to achieve rotation. The simulator 1 will then drive the connecting shaft 308 on the right frame 303 to disengage from the support 301 through the abutment connection of the locking rod 304. The support 301 is provided with a semi-circular groove 306, so the connecting shaft 308 has a degree of freedom in the upper part. Therefore, when the simulator 1 lifts up, it will drive the connecting shaft 308 to rotate, which in turn drives the intermediate rod 312 to rotate. The rotation of the intermediate rod 312 will drive the long shaft 310 connected to it to rotate. Under the condition that the long shaft 310 rotates, it will drive the connecting rotating plate 3071 to rotate. Then, the connecting rotating plate 3071, with the animation pen 3072, will draw an arc-shaped line with a flip angle on the drawing board 3073. Finally, after the inspection is completed, the operator can directly pull out the drawing board 3073 and determine the tilt angle of the simulated vehicle 1 during each inspection based on the length of the arc-shaped scribing line. This allows them to determine at what speed the simulated vehicle 1 is more stable when braking. Since the carrier component of the simulated vehicle 1 is located between the two long shafts 310, the simulated vehicle 1 relies primarily on the inertial motion of the carrier component to control the movement of the long shafts 310 during operation and inspection. Therefore, the movement of the carrier component will cause the long shafts 310 to disengage from the groove 3091, achieving the tilt inspection.

[0023] In addition, a long tube 3075 is connected to the card holder 3074, and a ball 3077 is slidably connected inside the long tube 3075. A long groove is opened on the long tube 3075, and a Z-link 3076 is slidably connected to the long groove. The Z-link 3076 abuts against the side of the drawing board 3073. To prevent the pen 3072 from drawing lines in the same position, the ball 3077 is provided. Whenever the linear motor 2 decelerates during sliding, the ball 3077 will have a forward inertial force controlled by the principle of inertia. Then, the ball 3077 will "impact" the drawing board 3073 and move it forward a certain distance through the connection of the Z-link 3076. Therefore, the motion posture at this time is such that the drawing board 3073 will be controlled to move a small segment during each detection, so as to avoid the pen 3072 repeatedly drawing lines in the same area during cyclic detection.

[0024] In addition, the weight-removing component 4 includes a load-bearing component and a material-removing component; the load-bearing component includes a sleeping chamber 403, a counterweight plate 44 is disposed inside the sleeping chamber 403, the sleeping chamber 403 is disposed on the top material tray of the simulator 1, and a chute 406 is provided at the bottom of the sleeping chamber 403. The material-removing component includes an insert plate 401, a hook 402 is connected to the insert plate 401, a pull ring 405 is connected to the left side of the counterweight plate 404, multiple counterweight plates 404 are provided, and the accumulated weight of multiple counterweight plates 404 simulates the pressure weight of the sleeping chamber (403) actually borne by the simulator 1. The overall testing also includes a weight-collecting component 4, designed to automatically change the load weight of the simulator 1 and detect its transport posture. Specifically, when the simulator 1 moves to its left limit position, the hook 402 slides into the pull ring 405, and the barb on the surface gets stuck in the pull ring 405. Then, with the resetting movement of the linear motor 2, the hook 402 pulls out the bottom counterweight 404 from the slot 406, thus reducing the load on the simulator 1 due to the automatic removal of the counterweight 404. Each cycle involves the removal of one counterweight 404, thereby detecting the load weight and movement speed of the simulator 1 and the changes in its operating posture. This allows for the detection of actual vehicle speed control based on the pressure in the sleeper 403 when it is loaded.

[0025] It is worth noting that the card holder 3074 has a spring plate inside, with one end of the spring plate connected to the card holder 3074 and the other end abutting against the drawing board 3073, achieving elastic compression and fixation of the drawing board 3073. The main purpose of the spring plate is to prevent the drawing board 3073 from being pushed too far when the ball 3077 is subjected to motion inertia. The drawing board 3073 has a certain amount of resistance, so each time the ball 3077 impacts and pushes, it will only push the drawing board 3073 a small distance, achieving continuous marking and drawing.

[0026] All electrical components mentioned in this article are connected to an external main controller and 220V AC mains power, and the main controller can be a conventional known device such as a computer that provides control.

[0027] The working principle is as follows: First, during the simulation test, the simulated vehicle 1 needs to be placed on the platform (not marked in the attached diagram) with its wheels in contact with the platform. The entire simulated vehicle 1 is mounted on the linear motor 2. Then, the locking rod 304 is manually extended to allow the simulated vehicle 1 to be placed inside the positioning device. The left baffle 311 is rotatably connected to the semicircular sleeve 309 and connected to the long shaft 310. Therefore, when the simulated vehicle 1 tilts and rotates, it will synchronously drive the left side frame 302 to rotate. Under relative conditions, the position of the left side frame 302 will not change. When the simulated vehicle 1 flips and tilts, it will drive the left baffle 311 or the locking rod 304 to rotate in contact. There is a gap space between the left baffle 311 and the locking rod 304. When the simulated vehicle 1 is subjected to inertial impact, it will drive the left baffle 311 or the locking rod 304 on one side to rotate, with the center of the long shaft 309 as the center of rotation. The entire process uses linear motor 2 as the power source for the movement of the simulator 1. Although the simulator 1 can run on its own, it relies on its internal battery. Therefore, to avoid the reduction in running speed due to power consumption during testing, which would lead to inaccurate test values, the overall testing utilizes the movement of linear motor 2 as the power source for the operation and testing of the simulator 1. Then, the linear motor 2 is controlled to reciprocate. When the linear motor 2 moves, it will drive the left frame 302 and the right frame 303 on the two connecting shafts 308 to move synchronously through the connection of the two supports 301. The simulator 1 located between the left frame 302 and the right frame 303 will be pushed by the left stop 311 or the locking rod 304 and move synchronously. If the linear motor 2 is facing the left side, that is, the front of the simulator 1, it will rely on the thrust of the locking rod 304 as a "pusher" to push the simulator 1 to move. After the linear motor 2 reaches a certain speed, it will decelerate. After deceleration, the simulator 1 may be subjected to the gravity above, and the tail may lift up, resulting in a flip. This is because when the simulator 1 is carrying the sleeping pod 403, if the simulator 1 moves at a certain speed and then decelerates for transfer, the sleeping pod 403 will slide down due to inertia or shift the center of gravity of the simulator 1, causing the tail of the simulator 1 to lift up, thus causing the sleeping pod 403 to slide down and the simulator 1 to flip over.Therefore, when the linear motor 2 causes the simulator 1 to "flip" at a certain speed, the simulator 1 will rotate around the long shaft 310 on the left side frame 302 as the center of rotation. The "lowering head" of the simulator 1 will cause the left stop frame 311 or the locking rod 304 to rotate, simultaneously driving the connecting shaft 308, the right side frame 303, and the tail of the locking rod 304 to tilt upwards, thus achieving rotation. The simulator 1 will then drive the middle rod 312 to rotate around the center of the long shaft 310 through the downward pressure of the rotation of the left stop frame 311. This is because the simulator is being pushed by the "pusher". After movement, the deceleration of the linear motor 2 will cause the left side of the simulator 1 to contact and abut against the left baffle 311. Initially, there is no contact. After contact, if a rollover occurs, the rear of the simulator 1 will lift up. At this time, the locking rod 304 at the rear will create a certain distance from the simulator 1, providing space for the rear of the simulator 1 to lift up and avoiding interference with the locking rod 304. The support 301 is provided with a semi-circular groove 306, so the connecting shaft 308 has a degree of freedom in the upper part. Therefore, when the simulator 1 lifts up... This will cause the connecting shaft 308 to rotate, because at this time the connecting shaft 308, the right side bracket 303, and the locking rod 304 will be a whole, which in turn will cause the intermediate rod 312 to rotate. The rotation of the intermediate rod 312 will cause the connected long shaft 310 to rotate. Under the condition of the long shaft 310 rotating, the connecting rotating plate 3071 will rotate. Then, the connecting rotating plate 3071, with the animation pen 3072, will draw an arc-shaped line on the drawing board 3073 to mark the rotation angle, thus drawing the rotation angle mark on the drawing board 3073. Furthermore, to prevent the pen 3072 from drawing lines in the same position, a sphere 3077 is incorporated. Whenever the linear motor 2 decelerates during sliding, the sphere 3077 is controlled by inertia to maintain a forward inertial force. The sphere 3077, connected by the Z-link 3076, then "collides" with the drawing board 3073, moving it forward a certain distance. Therefore, during each test, the drawing board 3073 is controlled to move slightly, preventing the pen 3072 from repeatedly drawing lines within the same area during cyclic testing. Finally, after the test is completed, the operator can directly remove the drawing board 3073 and determine the rotation angle of the simulated vehicle 1 during each test based on the length of the arc-shaped line. When the linear motor 2 resets and slides, simulating the state of "reversing," the rotation center will be around the connecting shaft 308 on the right frame 303, and the connecting shaft 308 on the left frame 302 will disengage from the semi-circular groove 306 on the support 301, forming a "tilted" state. The display device 307 is also synchronously set on the right frame 303, so the state of the simulated vehicle 1 reversing will be recorded in real time. Finally, the entire system realizes the bidirectional load-bearing motion speed detection of the simulated vehicle 1.The overall detection also includes a weight-collecting component 4, the purpose of which is to detect the transport posture of the simulator 1 by automatically changing the load weight of the simulator 1. Specifically, when the simulator 1 moves to the left limit position, the hook 402 will slide into the pull ring 405 position, and the barb on the surface will be stuck in the pull ring 405 position. Then, with the reset movement of the linear motor 2, the hook 402 will pull out the bottom counterweight plate 404 in the sleeping chamber 403 and disengage it from the slot 406 position. Therefore, the weight of the load-bearing component is reduced due to the automatic removal of the counterweight plate 404, thereby reducing the load weight of the simulator 1. So, each cycle will realize the removal of the counterweight plate 404 piece by piece, thereby detecting the load weight and movement speed of the simulator 1, and detecting the numerical changes in the running posture of the simulator 1. The overall operating conditions can be controlled by the operator. For example, the speed of the linear motor 2 can be set to be uniform each time. In this case, the detection condition is the effect of the running load of the simulator 1 on the overturning of the simulator 1 at the same speed. If the change in the attitude of the simulator 1 at different speeds is to be detected, the weight-removing component 4 is directly removed, preventing it from pulling away the counterweight 404. The detection condition then becomes the impact of the simulator 1's operating attitude at different speeds under the same load. Simultaneously, dual detection is possible: as the load on the simulator 1 decreases under constant acceleration or deceleration, the change in its operating attitude is observed. Therefore, actual testing can be conducted under operating conditions set by the operator, ultimately determining the simulator 1's limit stability values ​​at different weights and speeds. This allows for the simulation of how changing the pressure and weight of the sleeping chamber affects the simulator 1's operating speed.
