In addition, according to the fuel type, it can also be divided into traditional heavy-duty truck tractors and new energy heavy-duty truck tractors, which use the power of their own engines to drive the vehicle forward, backward or turn.

DETAILED DESCRIPTION

[0028] The present invention is further described below by way of examples, but the present invention is not limited to the scope of the examples.

[0029] like Figure 1-10 As shown, the device capable of turning in conjunction with the vehicle comprises: A van-type semitrailer assembly 100, the van-type semitrailer assembly 100 is composed of a cab 102 and a carriage 105, the cab 102 is provided with a deflector assembly 200 at the rear side, the deflector assembly 200 is composed of deflectors 201 (i.e., installed on both sides of the rear part of the cab) and an adjustment mechanism, the deflectors 201 are rotatably connected to both sides of the cab 102, and the adjustment mechanism is arranged between the deflectors 201 and is transmission-connected to the deflectors 201; The protection component 300 is fixedly mounted on the top of the cab 102, and a shielding mechanism is slidably connected to the protection component 300, and when the shielding mechanism falls, the shielding mechanism is arranged on one side of the adjustment component 400 corresponding to you; The adjusting component 400 is fixedly mounted to one side of the vehicle compartment 105 , and the adjusting component 400 is arranged corresponding to the guide plate 201 , and both the adjusting component 400 and the guide plate 201 are located between the cab 102 and the vehicle compartment 105 for airflow guidance.

[0030] Preferably, the air deflectors 201 at the rear of both sides of the cab can be rotated outward at an angle of 0 to 180 degrees when the tractor turns, or the movable plates 402 on both sides can slide backward to a certain position to prevent the carriage 105 of the rear semi-trailer from colliding with or interfering with the deflectors 201 when turning.

[0031] Specifically, when the heavy-duty truck tractor is turning, the steering angle sensor in the steering wheel sends a signal to the angle signal receiver 114 and transmits it to the control panel 110. The control panel 110 controls the action of the guide assembly 200. According to the signal input by the steering progress sensor in the steering wheel, when the vehicle turns left, the guide plate 201 on the left side is turned to a certain angle, and the moving plate 402 moves forward to a certain position; and the angle at which the guide plate 201 is turned matches the angle at which the vehicle turns. The greater the vehicle turns, the greater the angle at which the guide plate 201 is turned. At the same time, the guide plate 201 on the other side rotates in the opposite direction, which can solve the influence of the guide plate 201 on the turning radius when turning; similarly: when the vehicle turns right, the guide plate 201 on the right side is turned to a certain angle, while the guide plate 201 on the left side is reversed by the same angle.

[0032] The cab 102 is fixedly mounted on the top of the chassis 101, and the bottom of the chassis 101 is rotatably connected to the front wheel 103. A trailer seat 104 is fixedly mounted on the rear of the chassis 101 on one side of the cab 102, and a carriage 105 is rotatably connected to the trailer seat 104. The bottom of the carriage 105 is rotatably connected to the rear wheel 106. A deflector 107 is fixedly mounted on the top of the cab 102, and the deflector 107 is located above the top surface of the carriage 105 for airflow guidance, and a wing plate 108 is fixedly connected to the bottom of the deflector 107; A shell 109 is fixedly installed inside the driving room 102, and the shell 109 is fixedly connected to the control panel 110, the speed sensor 111, the pressure signal receiver 112 and the flow rate signal receiver 113 respectively. A turning angle signal receiver 114 is fixedly connected to the top of the shell 109, and the control panel 110 is electrically connected to the speed sensor 111, the pressure signal receiver 112 and the flow rate signal receiver 113 respectively, and the turning signal receiver is electrically connected to the steering wheel angle sensor of the van semi-trailer assembly 100.

[0033] In the present technical solution, the chassis 101 realizes the installation of the cab 102, and the towing of the carriage 105 is realized by the trailer seat 104. When the steering is realized by the front wheel 103, the carriage 105 moves through the rear wheel 106 and rotates around the trailer seat 104. When the carriage 105 drives the adjustment component 400 thereon to rotate, the avoidance between the guide plate 201 is realized by the extension and contraction of the moving plate 402. At the same time, the guide plate 201 rotates to a certain angle and fits with the guide plate 201. At this time, the area between the cab 102 and the carriage 105 is shielded, thereby preventing the airflow from entering the area and forming turbulence, and the driver can The air above the chamber 102 is guided by the deflector 107, and the airflow is guided by the deflector 107 tilted upward, so that the airflow will not enter between the cab 102 and the compartment 105, and a housing 109 is set in the cab 102 for installing the control system, so that the deflector component 200 and the adjustment component 400 can be linked with the vehicle turning, so that the deflector plate 201 and the moving plate 402 are always in contact with each other during the turning process, and the airflow guidance processing is realized without affecting the smooth turning of the vehicle, so that the semi-trailer can ensure effective turbulence elimination when driving on straight roads and curved roads. The speed sensor 111 monitors the speed of the vehicle, the velocity signal receiver 113 monitors the airflow velocity during the vehicle's driving, and the pressure sensor 209 monitors the pressure of the gas at the deflector 201. After the pressure signal is transmitted to the pressure signal receiver 112, it is calculated and processed through the control panel 110. Under the current airflow velocity and the vehicle's driving speed, the pressure range of the deflector 201 is calculated. When the pressure value exceeds the preset range, it means that the airflow direction is close to the vertical state of the deflector 201. At this time, it is judged that the vehicle is subjected to crosswind. When the pressure signal receiver 112 receives When the pressure signal value is too large, the second hydraulic cylinder 207 is started, so that the second hydraulic cylinder 207 drives the fixed block 205 and the slide 203 to move. After the slide 203 moves inside the limit plate 202, the first hydraulic cylinder 204 drives the guide plate 201 to rotate. At the same time, the first hydraulic cylinder 204 is shortened to make the guide plate 201 rotate further, and then the guide plate 201 is completely folded. At this time, a space for crosswind circulation is formed between the cab 102 and the car body 105, thereby reducing the resistance to the vehicle in the crosswind state, ensuring the stability of the vehicle during driving, and effectively solving the problem of the box semi-trailer being affected by crosswind.

[0034] There are two deflectors 201 disposed on both sides of the vehicle, the inner wall of the deflector 201 is fixedly connected with a pressure sensor 209, the adjustment assembly 400 is mounted to the rear side wall of the cab 102, and the adjustment assembly 400 is composed of a limit plate 202, the limit plate 202 has a U-shaped cross-section and is fixedly connected to the outer wall of the cab 102, a U-shaped slide seat 203 is slidably connected inside the limit plate 202, the slide seat 203 is rotatably connected to the first hydraulic cylinder 204, and the telescopic end of the first hydraulic cylinder 204 is rotatably connected to the pressure sensor 209, The top of the guide plate 201 is fixedly connected to the limiting block 208, one end of the limiting plate 202 is fixedly connected to the fixing plate 206, and the side wall of the fixing plate 206 is fixedly installed with the second hydraulic cylinder 207, one side of the slide seat 203 is fixedly connected to the fixing block 205, and the telescopic end of the second hydraulic cylinder 207 is fixedly connected to the fixing block 205, the first hydraulic cylinder 204 and the second hydraulic cylinder 207 are both electrically connected to the control panel 110, and the top of the cab 102 is fixedly connected to the flow rate sensor 210, and the flow rate sensor 210 is electrically connected to the flow rate signal receiver 113.

[0035] In the present technical solution, during the driving process of the vehicle, when the vehicle moves in a straight line, the guide plate 201 and the two sides of the cab 102 overlap with each other. At this time, the third hydraulic cylinder 407 drives the movable plate 402 to move out and contact with the guide plate 201. At this time, the airflow is circulated from the surfaces of the guide plate 201 and the movable plate 402, thereby realizing airflow guidance. When the vehicle turns, the cab 102 drives the guide plate 201 to rotate, and the vehicle steering signal is monitored by the vehicle's steering wheel angle sensor. The vehicle steering angle is received by the turn signal receiver, and the data is transmitted to the control panel 110. Then, the control panel 110 controls the extension and retraction of the first hydraulic cylinder 204, and the first hydraulic cylinder 204 drives the guide plate 201 to rotate. After the rotation, the third hydraulic cylinder 407 is started again, and the movable plate 402 continues to contact one side of the guide plate 201 according to the position of the guide plate 201, thereby ensuring the connection between the guide plate 201 and the movable plate 402, effectively reducing the generation of turbulence, and not affecting the steering of the vehicle.

[0036] The protection component 300 is composed of a track 301, which is an L-shaped structure and is arranged above the cab 102. The two ends of the track 301 are fixedly connected to the top of the cab 102 and the chassis 101 respectively. A long hole 302 is opened in the middle of the track 301, and a shielding mechanism is slidably connected inside the long hole 302. A traction mechanism is fixedly installed on the top of the cab 102 located on one side of the track 301, and the traction mechanism and the track 301 are both located inside the deflector 107; the shielding mechanism is composed of a sliding rod 303, and the sliding rod 303 is slidably connected to the inside of the long hole 302. The two ends and the middle of the sliding rod 303 are fixedly connected to the limit shaft 304, and the limit shafts 304 at both ends are fixedly connected to the deflector The plate 201 contacts the inner wall, and the two limit shafts 304 located in the middle are respectively located on both sides of the track 301, and the limit shafts 304 are distributed correspondingly to the limit blocks 208, and the sliding rods 303 located on both sides of the track 301 are fixedly connected to the connecting plates 305, and the two connecting plates 305 are fixedly connected by connecting rods 306, and the connecting rods 306 are located on the surface of the track 301; the traction mechanism includes a drive motor 308, and the drive motor 308 is fixedly installed to the top of the cab 102 inside the air deflector 107, and the output end of the drive motor 308 is fixedly connected to a winding wheel 309, and a traction rope 310 is provided on the surface of the winding wheel 309, and the traction rope 310 is fixedly connected to the cross bar on one side of the cover cloth 307.

[0037] In the present technical solution, during the use of the vehicle, the deflector 201 rotates and adjusts the angle with the steering, and cooperates with the extension and retraction of the movable plate 402 to achieve the blocking of both sides of the space between the cab 102 and the compartment 105. Before the vehicle travels, the drive motor 308 is started to drive the winding wheel 309 to rotate, thereby driving the traction rope 310 to be wound on the surface of the winding wheel 309. The traction rope 310 pulls the cross bar and the cover cloth 307 to move upward. When the cover cloth 307 drives the connecting plate 305 and the connecting rod 306 to move upward, it pulls the slide bar 303 in the long hole 301 of the track 301. 2 moves inside, and the sliding rod 303 is limited by the limiting shaft 304 to achieve its stable movement, thereby driving the cover cloth 307 to be retracted, which does not affect the normal operation of the guide plate 201. When the vehicle is finished driving, the driving motor 308 is started to make the winding wheel 309 loosen the traction rope 310, and the deadweight of the connecting plate 305 and the sliding rod 303 causes the cover cloth 307 to move downward, and shield and protect the first hydraulic cylinder 204 and the second hydraulic cylinder 207. At this time, the cover cloth 307 is located between the guide plates 201, which plays a role in dust protection, is suitable for protecting the vehicle when not in use, and is convenient for subsequent use.

[0038] The adjustment assembly 400 is composed of a sleeve plate 401 and a movable plate 402. The sleeve plate 401 is fixedly connected to one side of the carriage 105. There are two sleeve plates 401 and both are U-shaped structures. The two sleeve plates 401 are inclined structures and are arranged at both ends of the carriage 105. The inside of each sleeve plate 401 is slidably connected with a movable plate 402. Slide grooves 403 are provided inside both sides of the movable plate 402. Both ends of the sleeve plate 401 on the same side are penetrated and plugged with a latch 404. One end of the latch 404 extends into the inside of the slide groove 403, and the other end of the latch 404 is connected to the sleeve plate 401 through a spring 405. The spring 405 and The latch 404 is sleeved, and a notch 406 is provided on the surface of the latch 404, and the notch 406 is located in the gap between the movable plate 402 and the sleeve plate 401; a third hydraulic cylinder 407 is fixedly connected to the inner wall of the movable plate 402, and the telescopic end of the third hydraulic cylinder 407 is fixedly connected to the end head 408, and a fixed seat 409 is fixedly connected to the side wall of the carriage 105, and the fixed seat 409 is an inclined structure and is arranged on the inner side of the sleeve plate 401, and the fixed seat 409 is a flat structure and an opening 410 is provided inside one side, and an end head 408 is embedded in the opening 410 to facilitate the end head 408 to be moved out from the inside of the opening 410.

[0039] In the present technical solution, the end 408 on the third hydraulic cylinder 407 is connected to the fixed seat 409. When the third hydraulic cylinder 407 is started, it drives the movable plate 402 to move inside the sleeve plate 401, and the elasticity of the spring 405 drives the end of the latch 404 to press against the arc groove. When moving, stable movement is achieved through the limitation of the latch 404 and the slide groove 403. When the rotation of the guide plate 201 or the movement of the movable plate 402 fails, interference may occur during the steering process. To ensure normal rotation during steering, when the guide plate 201 collides with the movable plate 402, when the direction of the collision of the movable plate 402 is inward, the latch 404 is subjected to force, which can make the latch 404 disengage from the inside of the slide groove 403. When the direction of the collision of the movable plate 402 is outward, the movable plate 402 rotates around the latch 404 and drives the end 408 to disengage from the opening 410 inside the fixed seat 409, thereby ensuring stable steering of the vehicle.
