Description

[0002] With the development of the times, more and more people like to go on self-driving tours. When driving a vehicle to the wild, a roof sleeping cabin can be used for rest. This can not only save the trouble of finding a hotel and the cost of staying in a hotel, but also get close to nature and enjoy the night scenery.

[0003] Currently, the sleeping cabin is basically installed on the roof of the car. During the operation of the car, it needs to carry the sleeping cabin and move synchronously. However, the sleeping cabin generally has a certain weight and pressure. When the car is driving, because the sleeping cabin is located on the roof of the car, when braking or accelerating, the sleeping cabin will generate a certain inertial load on the vehicle. If the pressure of the sleeping cabin is too large or the speed is too high, during the driving process of the vehicle, the sleeping cabin will cause the rear of the car to tilt slightly, resulting in unstable driving of the vehicle. At present, there is no simulation detection device for the weight of the sleeping cabin and the actual situation of the vehicle to determine the safe driving speed of the vehicle when carrying the sleeping cabin.

[0018] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0019] Please refer to Figures 1 - 8 , a roof sleeping cabin compression test detection device, including a simulation vehicle 1; a linear motor 2 for providing the motion state of the simulation vehicle 1; a detection assembly 3 for detecting the motion postures of weight and speed of the simulation vehicle during the transportation of the sleeping cabin 403; the detection assembly 3 includes a positioning device, a two-way free device and a display device 307; the positioning device is connected to the simulation vehicle 1 for fixing with the simulation vehicle 1; the two-way free device is used to provide the inertial flipping freedom generated when the simulation vehicle 1 moves forward or backward; the display device 307 is used to record the angle flipping generated by the motion simulation of the simulation vehicle 1 in real time; the positioning device is connected to the simulation vehicle 1, the two-way free device is connected to the positioning device, and the display device 307 is connected to the positioning device; and a weight-taking assembly 4 for regulating the load-bearing of the simulation vehicle 1 during each cycle of detection.

[0020] In this embodiment, the positioning device includes a left frame 302 and a right frame 303. A left stop frame 311 is connected to the left side of the left frame 302. Semi-circular sleeves 309 are respectively connected to the left frame 302 and the right frame 303. The left stop frame 311 and a locking rod 304 are respectively rotatably connected to the two semi-circular sleeves 309. The simulation vehicle 1 is located between the locking rod 304 and the left stop frame 311. When the simulation vehicle 1 moves, it relies on the respective abutments of the left stop frame 311 and the locking rod 304 to push the linear motion of the simulation vehicle 1.

[0021] Furthermore, the bidirectional free device includes two supports 301. The supports 301 are connected to the linear motor 2. A semi-circular groove 306 is formed on the support 301. A connecting shaft rod 308 is connected in the semi-circular groove 306. The two connecting shaft rods 308 are respectively connected to the left frame 302 and the right frame 303. Semi-circular sleeves 309 are connected to both the left frame 302 and the right frame 303. Grooves 3091 are formed on the semi-circular sleeves 309. A long shaft 310 is connected in the grooves 3091. An intermediate rod 312 is connected between the two long shafts 310. There are two display devices 307, which are respectively arranged on the left frame 302 and the right frame 303. By setting the bidirectional free device, when the simulation vehicle 1 makes a reciprocating motion simulation, it can realize double detection of "forward" and "reverse", directly simulate the running postures of moving forward and avoiding obstacles and reversing, improve the simulation diversity of the simulation vehicle 1, and provide certain data references for subsequent actual operations. Because relatively speaking, the power output depends 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 is used to push the positioning device to move, and then indirectly push the motion simulation of the simulation vehicle 1.

[0022] Furthermore, the display device 307 includes a card holder 3074, a slot is provided on the card holder 3074, a drawing board 3073 is inserted into the slot, the card holder 3074 is installed on the left frame 302, a connecting rotating piece 3071 is fixedly connected to the long axis 310, a paintbrush 3072 is installed on the connecting rotating piece 3071, the tip of the paintbrush 3072 is in contact with the drawing board 3073, and when the simulated car 1 is performing a motion flip, the paintbrush 3072 will be controlled to draw a trajectory on the drawing board 3073. When the linear motor 2 causes the simulation car 1 to "flip over" at a certain speed, the simulation car 1 will use the long axis 310 on the left frame 302 as the rotation center, lift up its tail and realize rotation. The simulation car 1 will drive the connecting shaft 308 on the right frame 303 to separate from the support 301 through the abutment connection of the locking rod 304. The support 301 is provided with a semicircular groove 306, so the connecting shaft 308 has an upward degree of freedom. Therefore, when the simulation car 1 is lifted up, it will drive the connecting shaft 308 to rotate, and then drive the middle rod 312 to rotate. The rotation of the middle rod 312 will drive the long axis 310 connected to it to rotate. When the long axis 310 rotates, it will drive the connecting rotating plate 3071 to rotate. Then the connecting rotating plate 3071 drives the drawing pen 3072 to draw an arc line of the flip angle on the drawing board 3073. Finally, after the test is completed, the operator can directly draw out the drawing board 3073 and judge the flip angle of the simulated car 1 during each test according to the length of the arc-shaped line, so as to determine at what speed the simulated car 1 is more stable when braking. The bearing member of the simulated car 1 is located between the two long shafts 310, so when the simulated car 1 is running and testing, it basically relies on the inertial movement of the bearing member to control the movement of the long shaft 310, so the movement of the bearing member will cause the long shaft 310 to leave the position of the groove 3091 to achieve flip detection.

[0023] In addition, a long tube 3075 is connected to the bracket 3074, and a ball 3077 is slidably connected inside the long tube 3075. A long groove is provided on the long tube 3075, and a Z link 3076 is slidably connected to the long groove, and the Z link 3076 abuts against the side of the drawing board 3073. In order to prevent the brush 3072 from marking at the same position, the ball 3077 is provided. Whenever the linear motor 2 decelerates during sliding, the inertia principle is used to control the ball 3077 to have a forward inertial force, and then the ball 3077 will "impact" the drawing board 3073 through the connection of the Z link 3076 to move forward a certain distance. Therefore, the movement posture at this time is that each time the detection is performed, the drawing board 3073 will be controlled to move in a small section by itself, so as to avoid the brush 3072 from repeatedly marking in an area during the cyclic detection.

[0024] In addition, the weight-taking component 4 includes a carrier and a material-taking component; the carrier includes a sleeping cabin 403, a counterweight sheet 404 is arranged inside the sleeping cabin 403, the sleeping cabin 403 is arranged on the top material tray of the simulation vehicle 1, and a release groove 406 is formed at the bottom of the sleeping cabin 403. The material-taking component includes a plug board 401, a hook 402 is connected to the plug board 401, a pull ring 405 is connected to the left side of the counterweight sheet 404, and a plurality of counterweight sheets 404 are provided, and the accumulated weight of the plurality of counterweight sheets 404 is used to simulate the pressure weight of the sleeping cabin (403) actually carried by the simulation vehicle 1. The weight-taking component 4 is also provided in the overall detection, and the purpose is to detect the transportation attitude of the simulation vehicle 1 by automatically changing the carrying weight of the simulation vehicle 1. Specifically, when the simulation vehicle 1 moves to the left extreme position, the hook 402 will slide into the position of the pull ring 405, and the barbs on the surface will be stuck in the position of the pull ring 405. After that, with the reset movement of the linear motor 2, the hook 402 will pull out the lowermost counterweight sheet 404 in the sleeping cabin 403 from the position of the release groove 406. Therefore, at this time, the weight of the carrier is reduced due to the automatic extraction of the counterweight sheet 404, thereby reducing the carrying gravity of the simulation vehicle 1. So, in each cycle, the single-piece extraction of the counterweight sheet 404 can be realized to detect the carrying weight and movement speed of the simulation vehicle 1, and the numerical value detection of the change in the running attitude of the simulation vehicle 1. Thus, it can be detected that when the actual vehicle is loaded with the sleeping cabin 403, the speed can be controlled according to the pressure of the sleeping cabin 403.

[0025] It should be noted that a spring piece is arranged inside the clamping frame 3074, one end of the spring piece is connected to the clamping frame 3074, and the other end of the spring piece abuts against the drawing board 3073 to elastically squeeze and fix the drawing board 3073. The main purpose of arranging the spring piece is to prevent the drawing board 3073 from being pushed too long a distance when the sphere 3077 is subjected to inertial movement during extrusion. There is a certain resistance in the overall drawing board 3073. Therefore, every time the sphere 3077 impacts and pushes, it will only push the drawing board 3073 to move a short distance to achieve continuous marking and scribing.

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

[0027] Working principle: first, when conducting simulation testing, the simulation car 1 needs to be placed as a whole on the table without any mark in the attached figure, so that the wheels of the simulation car 1 are in contact with the table, and the entire simulation car 1 is set on the linear motor 2, and then the locking rod 304 is manually stretched so that the simulation car 1 can be placed inside the entire positioning device, and the left stop frame 311 is rotatably connected to the semicircular sleeve 309 and connected to the long axis 310, so when the simulation car 1 is tilted and rotated, it will synchronously drive the left frame 302 to rotate, so under relative conditions, the position of the left frame 302 will not change, and when the simulation car 1 flips and tilts, it will drive the left stop frame 311 or the locking rod 304 to abut and rotate, and there is a gap between the left stop frame 311 and the locking rod 304 of the simulation car 1. When the simulation car 1 is knocked by inertia, it will drive the left stop frame 311 or the locking rod 304 on one side to rotate, with the center of the long axis 309 as the center of rotation. The entire process uses the linear motor 2 as the motive power for the simulated vehicle 1. Although the simulated vehicle 1 can run on its own, it relies on an internal battery. Therefore, during detection, it is necessary to avoid a reduction in operating speed due to power consumption, which would result in inaccurate detection values. Therefore, the overall detection utilizes the movement of the linear motor 2 as the motive power for the running detection of the simulated vehicle 1. Then, the reciprocating motion of the linear motor 2 is controlled. When the linear motor 2 moves, the left frame 302 and the right frame 303 on the two connecting shafts 308 will be driven to move synchronously through the connection of the two supports 301, and the simulation car 1 located between the left frame 302 and the right frame 303 will be pushed by the left stop frame 311 or the locking rod 304 and follow the synchronous movement. If the linear motor 2 is facing the left direction, that is, the front direction of the simulation car 1, it relies on the thrust of the locking rod 304 as a "push hand" to push the simulation car 1 to move. After that, the linear motor 2 slows down after reaching a certain speed. At this time, the decelerated simulation car 1 may have its tail lifted up and flip over due to the gravity carried on the upper side. Because when the simulation car 1 is running with the sleeping cabin 403 on its back, if the simulation car 1 moves at a certain speed and then slows down for transportation, the sleeping cabin 403 will slide down according to inertia or shift the center of gravity of the simulation car 1, resulting in the compression of the tail of the simulation car 1, thereby causing the sleeping cabin 403 to slide down and the entire simulation car 1 to flip over.Therefore, when the linear motor 2 is at a certain speed, causing the simulated car 1 to "flip over", the simulated car 1 will use the long axis 310 on the left frame 302 as the rotation center, and the "lower head" of the simulated car 1 will rotate the left block frame 311 or the locking rod 304, synchronously driving the connecting shaft 308, the right frame 303 and the tail of the locking rod 304 to tilt up and realize rotation, and the simulated car 1 will drive the middle rod 312 to rotate around the center of the long axis 310 through the rotation and downward pressure of the left block frame 311, because at this time the simulated car is pushed by the "push hand". After starting, the deceleration of the linear motor 2 will cause the left side of the simulated car 1 to contact and abut against the left stop frame 311. In the initial state, there is no contact. After abutting, if the simulated car 1 flips over, the tail of the simulated car 1 will tilt up, and at this time, the locking rod 304 at the tail will have a certain distance from the simulated car 1, which will provide a certain space for the tail of the simulated car 1 to tilt up and avoid interference with the locking rod 304. The support 301 is provided with a semicircular groove 306, so the connecting shaft 308 has the upper degree of freedom, so the simulated car 1 is tilted when it is tilted. The connecting shaft 308 will be driven to rotate, because at this time the connecting shaft 308, the right frame 303 and the locking rod 304 will be a whole, which will drive the middle rod 312 to rotate, and the rotation of the middle rod 312 will drive the long shaft 310 connected thereto to rotate, and when the long shaft 310 rotates, it will drive the connecting rotating piece 3071 to rotate, and then the connecting rotating piece 3071 drives the drawing pen 3072 to draw an arc line of the flipping angle on the drawing board 3073, and draw the flipping angle mark on the drawing board 3073, and In order to avoid the brush 3072 from marking the same position, a sphere 3077 is provided. Whenever the linear motor 2 decelerates during sliding, the sphere 3077 is controlled to have a forward inertial force by using the inertia principle. Then, the sphere 3077 will "impact" the drawing board 3073 through the connection of the Z connecting rod 3076 to move forward a certain distance. Therefore, the movement posture at this time is that the drawing board 3073 will be controlled to move a small section of itself every time a test is performed, so as to avoid the brush 3072 from repeatedly marking a line in a region during the cyclic test. Therefore, after the test is completed, the operator can directly pull out the drawing board 3073 and judge the flip angle of the simulated car 1 during each test according to the length of the arc-shaped line. When the linear motor 2 is reset and slides, the state of "reversing" is simulated. At this time, according to the same principle, the turning center will be the connecting shaft 308 on the right frame 303 as the rotation center, and the connecting shaft 308 on the left frame 302 will be separated from the semicircular groove 306 on the support 301, forming a "tilted head" state, and the display device 307 is also synchronously set on the right frame 303, so the state of the simulated car 1 when reversing will also be recorded in real time. Finally, the whole realizes the motion speed detection of the two-way load-bearing simulated car 1.Moreover, a weight-taking component 4 is also provided in the overall detection. The purpose is to detect the transportation attitude of the simulation vehicle 1 by automatically changing the load weight of the simulation vehicle 1. Specifically, when the simulation vehicle 1 moves to the left extreme position, the insertion hook 402 will slide into the position of the pull ring 405, and the barbs on the surface will be stuck at the position of the pull ring 405. Then, with the reset movement of the linear motor 2, the insertion hook 402 will extract the counterweight piece 404 at the bottom layer in the sleeping cabin 403 from the position of the release slot 406. Therefore, at this time, the weight of the bearing member is reduced due to the automatic extraction of the counterweight piece 404, thereby reducing the load gravity of the simulation vehicle 1. So, in each cycle, a single counterweight piece 404 will be extracted to detect the load weight and running speed of the simulation vehicle 1, and to detect the numerical changes in the running attitude of the simulation vehicle 1. The overall operating conditions can be controlled by the operator. For example, if the speed of the linear motor 2 is set to be uniform each time, the detection condition at this time is the influence of the running load of the simulation vehicle 1 on the flipping of the simulation vehicle 1 at the same speed. If the attitude change of the simulation vehicle 1 at different speeds is to be detected, the weight-taking component 4 is directly removed, so that the weight-taking component 4 no longer extracts the counterweight piece 404. At this time, the detection condition is the influence of the simulation vehicle 1 on its own running attitude at different speeds under the same load. At the same time, double detection can also be carried out. When the load weight of the simulation vehicle 1 is continuously decreasing under uniform acceleration or uniform deceleration, it has an impact on the running attitude change of the simulation vehicle 1. Therefore, the actual detection can be carried out according to the working conditions set by the operator, and finally the limit stability values of the simulation vehicle 1 at different weights and speeds can be detected, so as to realize the simulation of changing the pressure weight of the sleeping cabin and further the influence on the running speed of the simulation vehicle 1.
