Description

Technical Field

[0001] The present application relates to the field of wingspan vehicles, and in particular to a solar-powered wingspan vehicle compartment and a van. Background Art

[0002] A wingspan vehicle is a vehicle whose wings on both sides of the vehicle body can be opened by manual or hydraulic devices. Because it is convenient for loading and unloading goods, this type of truck is often used in logistics transportation. In the related art, the Chinese utility model patent with authorization publication number CN207106196U discloses a new energy logistics transport vehicle, which includes a cargo box, which includes a frame, a first side panel, a second side panel and a top panel. The first side panel and the second side panel are respectively located on both sides of the top panel and are both hinged to the top panel. Hydraulic cylinders are installed between the first side panel and the top panel, and between the second side panel and the top panel, for driving the first side panel and the second side panel to rotate so as to open the cargo box from both sides. Solar photovoltaic panels are installed on the first side panel, the second side panel and the top panel. A solar controller, a battery pack, an inverter and an electric motor are also installed at the front end of the transport vehicle. The solar photovoltaic panel is electrically connected to the solar controller through a wire. The solar controller is electrically connected to the battery pack and the inverter. The inverter is electrically connected to the electric motor. The electric motor is used to drive the logistics transport vehicle to move. This solution can increase the lighting area of the logistics transport vehicle by unfolding the first side panel and the second side panel, thereby improving the power conversion efficiency of the solar photovoltaic panel. The electricity generated by the solar photovoltaic panel can be stored in a battery pack or used by the electric motor.

[0003] Regarding the above-mentioned related technologies, the inventors found that during transportation, if there is sufficient sunlight, the solar photovoltaic panels on the cargo box can better absorb and convert light energy, but at the same time the temperature of the solar photovoltaic panels will also become higher. The heat of the solar photovoltaic panels is transferred to the cargo box, which will cause the temperature inside the cargo box to rise. For some trucks that do not have ventilation and cooling equipment in the cargo box, it may affect the goods transported in the cargo box, which is not conducive to the long-term storage and transportation of the goods. Summary of the Invention

[0004] In order to reduce the heat conducted to the cargo box by the solar photovoltaic panels, avoid excessively high temperatures inside the cargo box, and facilitate long-term storage and transportation of goods, the present application provides a solar wingspan carriage and van.

[0005] In a first aspect, the present application provides a solar wingspan carriage, which adopts the following technical solution:

[0006] A solar wingspan carriage, comprising a bottom plate, wherein both ends of the top surface of the bottom plate are fixedly connected to a front plate and a compartment door respectively, supports are provided on the top of the front plate and the top of the compartment door, a crossbeam is fixedly connected between the two supports, the length direction of the crossbeam is parallel to the length direction of the bottom plate, two top plates are provided on both sides of the length direction of the crossbeam, the length direction of the top plates is parallel to the length direction of the crossbeam, both sides of the length direction of the top plates can be rotated, two groups of drive assemblies are provided on the supports, the two groups of drive assemblies are respectively used to drive the two top plates to rotate, the two top plates are rotatably connected to a wing plate on the side away from the crossbeam, the wing plate can be fixed to the front plate and the compartment door by a lock, when the top plate rotates with the side close to the wing plate as the center, a gap appears between the top plate and the support, and the top surface of the top plate is detachably connected to a solar photovoltaic panel.

[0007] By adopting the above technical solution, when the compartment needs to be opened for loading and unloading, the lock of the fixed wing panel is opened, the driving assembly is started, and the driving assembly drives the top panel to rotate upward with the side close to the cross beam as the center, thereby driving the wing panel to move upward, and the compartment can be opened to facilitate loading and unloading of goods; when the compartment needs to be closed, the driving assembly drives the top panel to rotate downward with the side close to the cross beam as the center, thereby driving the wing panel to move downward, and then the wing panel is fixed to the front panel and the compartment door through the lock, thereby completing the closure of the compartment to facilitate the transportation of goods;

[0008] When the temperature of the solar photovoltaic panel on the roof is too high during transportation, the interior of the carriage needs to be cooled down. The drive assembly is started, and the drive assembly drives the end of the top panel close to the wing panel to rotate. Since the wing panel is locked, the end of the top panel close to the crossbeam can be rotated downward, so that a gap appears between the top panel and the support. At this time, the top of the carriage is opened. On the one hand, it is convenient for ventilation and heat dissipation in the carriage. On the other hand, the interval between the top panel and the interior space of the carriage reduces the heat transferred to the interior space of the carriage through the top panel by the solar photovoltaic panel, thereby cooling the interior space of the carriage.

[0009] Optionally, a slide groove is provided on the top surface of the support, a sealing plate is vertically slidably connected in the slide groove, a support spring is connected between the bottom surface of the sealing plate and the slide groove, and the top plate is located on the sealing plate and abuts against it.

[0010] By adopting the above technical solution, when the top plate is set horizontally, the support spring supports the sealing plate to abut against the top plate, thereby sealing the interior of the car to prevent rain seepage; and when the top plate rotates downward with the side close to the wing plate as the center, the sealing plate can be pushed into the slide groove, so that the top plate and the support are spaced apart to facilitate ventilation and heat dissipation in the car.

[0011] Optionally, a first rotating shaft and a second rotating shaft are respectively inserted and fixedly connected on both sides of the length direction of the top plate, the axes of the first rotating shaft and the second rotating shaft are parallel to the length direction of the top plate, the top plate is rotatably connected to the wing plate through the second rotating shaft, and the driving assembly includes a driving motor, which can drive the first rotating shaft and the second rotating shaft to rotate respectively.

[0012] By adopting the above technical solution, the first rotating shaft and the second rotating shaft on both sides of the top plate can be driven to rotate respectively by the same drive motor, so that the top plate can be rotated upward to drive the wing plate to move and thus open the car body, or the top plate can be rotated to open the upper space of the car body without affecting the wing plate to facilitate ventilation and heat dissipation. Two working modes can be achieved by one drive motor, saving energy.

[0013] Optionally, a fixed box is fixedly connected to the support, and the fixed box is located outside the car body and is opened toward one side of the top plate. A detachable first limit block and a second limit block are provided in the fixed box, and one end of the first rotating shaft extends between the first limit block and the second limit block and can rotate between the two. The first limit block is located above the second limit block and is fixedly connected to the fixed box. A two-way cylinder is provided in the fixed box, and a telescopic shaft of the two-way cylinder is fixedly connected to the second limit block. The two-way cylinder is used to drive the second limit block to move.

[0014] By adopting the above technical solution, when it is necessary to rotate around the first rotating shaft, the telescopic shaft of the two-way cylinder with the second limit block is extended to drive the second limit block to move below the first limit block, thereby fixing the first rotating shaft to facilitate rotation around it; when it is necessary to rotate around the second rotating shaft, it is only necessary to retract the telescopic shaft of the two-way cylinder with the second limit block to release the fixation of the first rotating shaft, so that the top plate can be rotated downward, thereby facilitating the switching of the rotation center of the top plate and facilitating timely ventilation and heat dissipation of the interior of the car during transportation.

[0015] Optionally, a drive shaft is inserted and fixedly connected on the top plate, and the drive shaft is located between the first rotating shaft and the second rotating shaft and is axially parallel to both. A first connecting rod is fixedly connected to the driving motor shaft, and the other end of the first connecting rod is rotatably connected to the second connecting rod, and the second connecting rod is rotatably connected to one end of the driving shaft, and the driving motor shaft is axially parallel to the driving shaft.

[0016] By adopting the above technical solution, since the drive shaft is arranged between the first rotating shaft and the second rotating shaft, the drive motor drives the drive shaft to rotate through the first connecting rod and the second connecting rod, thereby driving the top plate to rotate. Therefore, when the rotation center changes, it will not affect the drive of the drive shaft by the drive motor. Therefore, one drive motor can drive two rotation centers, saving energy.

[0017] Optionally, the other telescopic shaft of the bidirectional cylinder is provided with a support block, and the support block can abut against the side of the wing plate facing the top plate.

[0018] By adopting the above technical solution, since the top plate and the wing plate are rotatably connected, in the process of the top plate driving the wing plate to move, the wing plate always remains in a hanging state due to the action of gravity. Therefore, in order to avoid the wing plate colliding with the cargo during the downward movement, the end of the two-way cylinder provided with the support block can be extended to abut against the side of the wing plate facing the top plate, thereby supporting the wing plate and making the wing plate open, avoiding collision with the cargo and facilitating use.

[0019] Optionally, a water collecting trough is provided on the top of the beam, a water pump is provided in the water collecting trough, the water inlet of the water pump is connected to a water inlet pipe, the water outlet of the water pump is connected to two water spray pipes through a tee pipe, the two water spray pipes are respectively located above the two top plates, water spray holes are provided on the water spray pipes, and wiping sponges are provided on the two water spray pipes, and the wiping sponges are in contact with the surface of the solar photovoltaic panel, a sliding motor and a screw are provided in the water collecting trough, the sliding motor is used to drive the screw to rotate, a slide is slidably connected in the water collecting trough, the water pump is installed on the slide, and the screw is used to drive the slide to slide along the length direction of the beam.

[0020] By adopting the above technical solution, the water collection tank can be used to collect rainwater. When the solar photovoltaic panel needs to be wiped, the water pump is turned on, and the water pump draws water from the water collection tank and pumps it into two water spray pipes. The water spray pipes spray water onto the surface of the solar photovoltaic panel, which can not only clean the surface of the solar photovoltaic panel, but also cool the solar photovoltaic panel; start the sliding motor, the sliding motor drives the screw to rotate, the screw drives the slide to slide, and the slide drives the two water spray pipes to slide through the water pump, thereby driving the wiping sponge to wipe the surface of the solar photovoltaic panel to avoid the influence of dust on the solar photovoltaic panel's absorption of light energy; during the wiping process, the wiping sponge absorbs water while wiping, which can absorb the water flow in time to avoid the water flow from penetrating into the car.

[0021] Optionally, the water spray pipe includes a connected water spray hose and a water spray hard pipe, the water spray hose is connected to the tee pipe, the water spray hard pipe is located above the solar photovoltaic panel, the wing plate is provided with a guide groove on the side facing the top plate, the direction of the guide groove is parallel to the length direction of the top plate, and the water spray hard pipe is slidably connected in the guide groove at one end away from the water spray hose.

[0022] By adopting the above technical solution, the water spray pipe includes a water spray hose and a water spray hard pipe. When the top plate rotates, the water spray pipe can rotate with the top plate due to the provision of the water spray hose. When the water spray pipe slides, the water spray hard pipe can slide along the guide groove, thereby guiding the water spray pipe and improving the sliding stability of the water spray pipe.

[0023] Optionally, rainproof membrane cloth is bonded between the two top plates and the cross beam.

[0024] By adopting the above technical solution, a rainproof membrane cloth is bonded between the top plate and the cross beam, thereby preventing rainwater from entering the car compartment from between the top plate and the cross beam, and protecting the interior of the car compartment from dryness.

[0025] In a second aspect, the present application provides a van truck using a solar wingspan compartment, which adopts the following technical solutions:

[0026] A van truck using a solar wingspan compartment includes a body, a cab, a motor, a controller, a battery pack and an inverter. The cab is arranged in front of the top of the body, and the wingspan compartment is arranged behind the top of the body. The solar photovoltaic panel is electrically connected to the controller, the controller is electrically connected to the battery pack and the inverter, the inverter is electrically connected to the motor, and the motor is used to drive the truck to travel. Two groups of side panels are also hinged on both sides of the length direction of the bottom plate, and the bottom surface of the wing panel and the top surface of the side panel on the same side are abutted, and the side panels are connected to the front panel and the compartment door through locks. Each group of side panels includes two first side panels and one second side panel, and the second side panel is located between the two first side panels. The bottoms of the three are hinged to the bottom plate, and the three are also connected by locks.

[0027] By adopting the above technical solution, two groups of side panels are hinged on both sides of the length direction of the bottom plate, and each group of side panels includes a first side panel and a second side panel. When loading and unloading goods, opening the wing panel can open the upper space of the car body, and opening the side panel can open the lower space of the car body. In addition, only the first side panel or the second side panel can be opened as needed, so that the car body can be partitioned and opened according to the needs of loading and unloading goods.

[0028] In summary, this application includes at least one of the following beneficial technical effects:

[0029] 1. When the temperature of the solar photovoltaic panels on the roof is too high during transportation, the interior of the carriage needs to be cooled. The drive assembly is started, and the drive assembly drives the end of the roof close to the wing plate to rotate. Since the wing plate is locked, the end of the roof close to the crossbeam can be rotated downward, so that a gap appears between the roof and the support. At this time, the roof of the carriage is opened, which is convenient for ventilation and heat dissipation in the carriage. On the other hand, the distance between the roof and the interior space of the carriage is set to reduce the heat transferred from the solar photovoltaic panels to the interior space of the carriage through the roof, thereby cooling the interior space of the carriage;

[0030] 2. When the top plate is horizontally set, the support spring supports the sealing plate against the top plate, thereby sealing the interior of the car and preventing rain from seeping in. When the top plate rotates downward with the side closest to the wing plate as the center, the sealing plate can be pushed into the slide groove, thereby separating the top plate and the support to facilitate ventilation and heat dissipation in the car.

[0031] 3. The water collection tank can be used to collect rainwater. When the solar photovoltaic panel needs to be wiped, the water pump is turned on. The water pump draws water from the water collection tank and pumps it into two water spray pipes. The water spray pipes spray water onto the surface of the solar photovoltaic panel, which can not only clean the surface of the solar photovoltaic panel, but also cool the solar photovoltaic panel; start the sliding motor, the sliding motor drives the screw to rotate, the screw drives the slide to slide, and the slide drives the two water spray pipes to slide through the water pump, thereby driving the wiping sponge to wipe the surface of the solar photovoltaic panel to avoid the influence of dust on the solar photovoltaic panel's absorption of light energy; during the wiping process, the wiping sponge absorbs water while wiping, which can absorb the water flow in time to prevent the water flow from penetrating into the car.

The front plate 32 is fixedly connected to the top surface of the bottom plate 31 close to the cab 2, and the door 33 is fixedly connected to the top surface of the bottom plate 31 away from the cab 2. The two sets of side plates 36 are respectively arranged on both sides of the length direction of the bottom plate 31 and are located between the front plate 32 and the door 33. The tops of the front panel 32 and the compartment door 33 are fixedly connected with supports 37, and the length direction of the supports 37 is perpendicular to the length direction of the bottom panel 31. A crossbeam 38 is fixedly connected between the middle positions of the top surfaces of the two supports 37, and the length direction of the crossbeam 38 is parallel to the length direction of the bottom panel 31. The two top panels 34 are respectively arranged on both sides of the length direction of the crossbeam 38 and are located between the front panel 32 and the compartment door 33. The top panels 34 and the supports 37 are spaced apart, and the two wing panels 35 are respectively arranged on the side of the two top panels 34 away from each other.

[0044] Reference Figure 1 A set of solar photovoltaic panels 41 is detachably connected to both top panels 34. A set of solar photovoltaic panels 41 includes multiple solar photovoltaic panels 41, and the multiple solar photovoltaic panels 41 in a set are evenly arranged along the length of the top panels 34. In this embodiment, a set of solar photovoltaic panels 41 includes two solar photovoltaic panels 41. A main drive mechanism 5 is provided on the support 37 of the front panel 32, and a slave drive mechanism 6 is provided on the support 37 of the door 33. The top panels 34 are located between the main drive mechanism 5 and the slave drive mechanism 6. The two sets of drive mechanisms are used to drive the two top panels 34 to rotate. A wiping assembly 7 is also provided on the crossbeam 38 for wiping the solar photovoltaic panels 41 to keep their surfaces clean and improve their absorption of light energy.

[0045] Reference Figure 1 Each set of side panels 36 includes two first side panels 361 and one second side panel 362. The second side panel 362 is located between the two first side panels 361. The three side panels 36 are located on one side of the top surface of the bottom panel 31 in the longitudinal direction and in front of the front panel 32 and the door 33. The three side panels 36 are arranged along the length of the bottom panel 31. The bottoms of the two first side panels 361 are hinged to the bottom panel 31. The bottoms of the second side panels 362 are connected to the bottom panel 31 via locks 39. The second side panels 362 are also connected to the two first side panels 361 via locks 39. The front panel 32 and the door 33 are also provided with locks 39 for securing the adjacent first side panels 361. When loading and unloading cargo, the locks 39 on the side panels 36 can be opened and the side panels 36 can be flipped down to facilitate loading and unloading.

[0046] Reference Figure 1 and Figure 2The main drive mechanism 5 comprises a fixed housing 51 and two drive assemblies 52, each of which is used to rotate the two top plates 34. The fixed housing 51 is fixedly connected to the side of the support 37 facing away from the crossbeam 38. The length of the fixed housing 51 is parallel to the length of the support 37. The fixed housing 51 is open on the side facing the crossbeam 38 and at both ends. To facilitate drainage, grooves are provided on both ends of the bottom surface of the fixed housing 51. The two drive assemblies 52 are disposed within the fixed housing 51 and are symmetrically arranged relative to each other with the vertical plane of the crossbeam 38 axis as the plane of symmetry. The driving assembly 52 includes a driving motor 521, which is installed on the bottom wall inside the fixed box 51. A driving shaft 522 is inserted and fixedly connected to the top plate 34. The driving shaft 522 is axially parallel to the length direction of the top plate 34. The driving shaft 522 is located in the middle position in the width direction of the top plate 34. The driving shaft 522 is axially parallel to the rotating shaft of the driving motor 521. The rotating shaft of the driving motor 521 extends into the support 37 and is fixedly connected to a first connecting rod 523. The other end of the first connecting rod 523 is rotatably connected to the second connecting rod 524. The other end of the second connecting rod 524 is rotatably connected to the driving shaft 522. The first connecting rod 523 and the second connecting rod 524 both rotate in a plane parallel to the front plate 32.

[0047] Reference Figure 2 and Figure 3A first rotating shaft 525 is inserted and fixedly connected in the top plate 34. The axial direction of the first rotating shaft 525 is parallel to the axial direction of the driving shaft 522. The first rotating shaft 525 is located on the side of the top plate 34 close to the crossbeam 38. The side of the top plate 34 abutting the crossbeam 38 is set to an arc shape for easy rotation. A first limiting block 526 is fixedly connected to the top wall inside the fixed box 51. The first limiting block 526 is located above the first rotating shaft 525, and a semicircular first limiting groove 5261 is opened on the bottom surface of the first limiting block 526. The first rotating shaft 525 is coaxially connected to the first limiting groove 5261. A two-way cylinder 528 is also fixedly connected to the top wall inside the fixed box 51. The two-way cylinder 528 is located above the driving motor 521. The axial direction of the two-way cylinder 528 is parallel to the length direction of the fixed box 51. The two-way cylinder 528 is a telescopic cylinder. A second limit block 527 is fixedly connected to the shaft, and the two-way cylinder 528 drives the second limit block 527 to slide under the first rotating shaft 525. When the second limit block 527 slides to below the first limit block 526, the first rotating shaft 525 rotates in the first limit groove 5261 and the second limit groove 5271. The second limit groove 5271 is set to an opening on the side away from the two-way cylinder 528. When the telescopic shaft that fixes the second limit block 527 by the two-way cylinder 528 contracts, the second limit groove 5271 can be separated from the first rotating shaft 525. The wing plate 35 is rotatably connected to the side of the top plate 34 away from the first rotating shaft 525. The length direction of the wing plate 35 is parallel to the length direction of the top plate 34. A clearance groove 351 is opened on the side of the wing plate 35 facing the top plate 34. The clearance groove 351 is opened along the length direction of the wing plate 35. A second rotating shaft 529 is fixedly connected in the clearance groove 351. The side of the top plate 34 away from the first rotating shaft 525 is rotatably connected to the second rotating shaft 529.

[0048] Reference Figure 1 and Figure 2When the top plate 34 is set horizontally, the wing plate 35 is set vertically, the wing plate 35 is located above the side plate 36, and the wing plate 35 is located between the front plate 32 and the compartment door 33. The two ends of the wing plate 35 are locked with the front plate 32 and the compartment door 33 respectively through the lock 39. When the carriage 3 needs to be opened, the wing plate 35 needs to be opened and the two-way cylinder 528 is started. One end of the two-way cylinder 528, which is fixed with the second limit block 527, extends in the direction close to the first limit block 526. When it moves below the first limit block 526, the first rotating shaft is limited. At this time, the driving motor 521 is started to open the lock 39 on the wing plate 35, and the driving motor 521 drives the other end of the first connecting rod 523 to rotate upward. The first connecting rod 523 drives the other end of the second connecting rod 524 to rotate upward, and then drives the top plate 34 to rotate upward with the first rotating shaft 525 as the center through the driving shaft 522. The top plate 34 drives the wing plate 35 to move upward. Since the top plate 34 and the wing plate 35 are rotatably connected, in the process of the top plate 34 driving the wing plate 35 to move upward, the wing plate 35 is always kept in a hanging state under the action of gravity, which can save space, thereby facilitating opening in different occasions and improving the applicability of the wingspan car. When the wing plate 35 moves upwards until its bottom is located at the support 37, the carriage 3 can be fully opened to facilitate loading and unloading of goods.

[0049] Reference Figure 2 and Figure 3 When the cam 35 is lowered, the motor 521 is driven to reverse and the top plate 34 is driven to rotate downward through the first connecting rod 523 and the second connecting rod 524. The top plate 34 drives the cam 35 to move downward. At this time, the end of the support block 530 of the two-way cylinder 528 is extended to abut against the side of the cam 35 facing the top plate 34, thereby supporting the cam 35 and opening the cam 35 to prevent the cam 35 from colliding with the cargo during the downward movement. When the top plate 34 rotates to a horizontal state, the cam 35 returns to a vertical state. At this time, the cam 35 is fixed with the lock buckle 39, thereby completing the closure of the compartment 3 for transporting cargo.

[0050] Reference Figure 2 and Figure 3When the temperature of the solar photovoltaic panel 41 on the top plate 34 is too high during transportation, the end of the two-way cylinder 528 fixed with the second limit block 527 contracts, releasing the limit on the first rotating shaft 525 and starting the drive motor 521. The drive motor 521 drives the other end of the first connecting rod 523 to rotate downward, and the first connecting rod 523 drives the top plate 34 to rotate downward with the second rotating shaft 529 as the center through the second connecting rod 524. Due to the gap between the top plate 34 and the support 37, the top plate 34 can be rotated until the end close to the cross beam 38 abuts against the support 37. At this time, the top plate 34 is in a downward tilted state close to the end of the cross beam 38. There is a gap between the top plate 34 and the support 37, and the top of the carriage 3 is opened. On the one hand, it is convenient for ventilation and heat dissipation in the carriage 3. On the other hand, the gap between the top plate 34 and the internal space of the carriage 3 reduces the heat transferred from the solar photovoltaic panel 41 to the internal space of the carriage 3 through the top plate 34, thereby cooling the internal space of the carriage 3.

[0051] Reference Figure 4 To prevent rain from seeping through the gap between the top plate 34 and the support 37, a sealing plate 531 is installed between the top plate 34 and the support 37. A slot 371 is defined along the length of the top of the support 37. The sealing plate 531 slides vertically within the slot 371. Multiple support springs 532 are fixedly connected between the bottom surface of the sealing plate 531 and the bottom wall of the slot 371. When the top plate 34 is horizontally positioned, the support springs 532 support the sealing plate 531 against the top plate 34, thereby sealing the interior of the compartment 3 and preventing rain from seeping in. When the top plate 34 rotates downward, it pushes the sealing plate 531 into the slot 371, creating a gap between the top plate 34 and the support 37, facilitating ventilation within the compartment 3. The sealing plates 531 of the two drive assemblies 52 are located on either side of the crossbeam 38 along its length.

[0052] Reference Figure 1 The slave drive mechanism 6 and the main drive mechanism 5 are arranged relative to each other with the vertical plane where the midline of the top plate 34 in the length direction is located as the symmetrical plane. One end of the first connecting rod 523 of the slave drive mechanism 6 is rotatably connected to the support 37 at the top of the compartment door 33. Except that there is no drive motor 521, the other structures of the slave drive mechanism 6 are consistent with those of the main drive mechanism 5 and will not be repeated here.

[0053] Reference Figure 5The top surface of the top plate 34 is fixedly connected to the limiting rod 42 on one side near the cross beam 38, and the length direction of the limiting rod 42 is parallel to the length direction of the top plate 34. The solar photovoltaic panel 41 can be clamped between the limiting rod 42 and the wing plate 35. A fixing plate 43 is hinged on the limiting rod 42, and the fixing plate 43 is fixedly connected to a silicone strip 44 on the side facing the solar photovoltaic panel 41. A locking bolt 45 is threadedly connected to the fixing plate 43. When the solar photovoltaic panel 41 is clamped between the limiting rod 42 and the wing plate 35, the fixing plate 43 is rotated until the silicone strip 44 abuts against the solar photovoltaic panel 41, and then the locking bolt 45 is rotated to make the fixing plate 43 lock the solar photovoltaic panel 41, thereby fixing the solar photovoltaic panel 41 above the top plate 34.

[0054] Reference Figure 2 、 Figure 5 and Figure 6 The wiping assembly 7 includes a sliding motor 71, a screw 72, a water pump 741 and two water pipes 76. A water collecting trough 73 is provided on the top surface of the beam 38 along its length direction. The screw 72 is rotatably connected to the water collecting trough 73. The axial direction of the screw 72 is parallel to the length direction of the beam 38. The sliding motor 71 is installed at one end of the beam 38 and its rotating shaft is coaxially fixedly connected to the screw 72. The sliding motor 71 is used to drive the screw 72 to rotate. A slide 75 is slidably connected in the water collecting trough 73. The slide 75 is threadedly connected to the screw 72, and the water pump 741 is installed on the slide 75. The water inlet of the water pump 741 is connected to a water pump pipe 742, with the outlet of the water pump 741 facing downward. The water outlet of the water pump 741 is connected to a tee pipe 743. Two water spray pipes 76 are connected to the water outlet of the water pump 741 through the tee pipe 743. The two water spray pipes 76 are respectively located above the two top plates 34. The water spray pipes 76 include a fixedly connected water spray hose 761 and a water spray rigid pipe 762. The water spray hose 761 is connected to the tee pipe 743. The water spray rigid pipe 762 is slidably connected to the top plate 34. The wing plate 35 has a guide groove 352 along its length on the side facing the top plate 34. The end of the water spray rigid pipe 762 away from the water spray hose 761 is slidably connected to the guide groove 352. The water spray pipe 762 has multiple water spray holes 763 evenly distributed on the side facing the door 33. A wiping sponge 77 is fixedly connected to the side of the water spray pipe 762 facing the solar photovoltaic panel 41. The wiping sponge 77 is located on the side of the water spray holes 763 facing away from the door 33. In order to prevent rainwater from entering the compartment 3 from between the top plate 34 and the crossbeam 38, a rainproof film 78 is bonded between the two top plates 34 and the crossbeam 38 to prevent rainwater from entering the compartment 3.

[0055] The water collection tank 73 can be used to collect rainwater. When the solar photovoltaic panel 41 needs to be wiped, the water pump 741 is turned on. The water pump 741 draws water from the water collection tank 73 and pumps it into the two water spray pipes 76. The water spray pipes 76 spray water toward the solar photovoltaic panel 41. At the same time, the sliding motor 71 is started. The sliding motor 71 drives the lead screw 72 to rotate. The lead screw 72 drives the slide 75 to slide toward the door 33. The slide 75 drives the two water spray pipes 76 to slide toward the door 33 through the water pump 741, thereby driving the wiping sponge 77 to wipe the surface of the solar photovoltaic panel 41. During the wiping process, since the water is sprayed in front and the wiping sponge 77 is behind, the surface of the solar photovoltaic panel 41 can be moistened to facilitate wiping, and the water flow can be absorbed in time to prevent the water flow from penetrating into the car 3. At the same time, the water pump 741 is only turned on in the direction of sliding from the front panel 32 to the door 33, and is turned off when sliding in the opposite direction to prevent water from flowing onto the cab 2.

[0056] The implementation principle of Example 2 of the present application is as follows: when it is necessary to open the carriage 3 to load and unload goods, the two-way cylinder 528 is started, and one end of the two-way cylinder 528 fixed with the second limit block 527 extends in the direction close to the first limit block 526. When it moves below the first limit block 526, the first rotating shaft is limited. At this time, the drive motor 521 is started to open the lock 39 on the wing plate 35, and the drive motor 521 drives the other end of the first connecting rod 523 to rotate upward. The first connecting rod 523 drives the other end of the second connecting rod 524 to rotate upward, and then drives the top plate 34 to rotate upward with the first rotating shaft 525 as the center through the drive shaft 522. The top plate 34 drives the wing plate 35 to move upward, and the upper part of the carriage 3 is opened; then the lock 39 on the side panel 36 is opened, the side panel 36 is flipped down, and the lower part of the carriage 3 is opened; then the compartment door 33 is opened, thereby opening the carriage 3 as a whole.

[0057] When the carriage 3 needs to be closed, the side panels 36 are first flipped up and fixed with the lock 39, and the lower part of the carriage 3 is closed. Then the drive motor 521 is started, and the drive motor 521 is reversed, driving the top plate 34 to rotate downward through the first connecting rod 523 and the second connecting rod 524, and the top plate 34 drives the wing plate 35 to move downward. At this time, the two-way cylinder 528 is provided with one end of the support block 530 extending to abut against the side of the wing plate 35 facing the top plate 34, thereby supporting the wing plate 35 and making the wing plate 35 open to prevent the wing plate 35 from colliding with the cargo during the downward movement. When the top plate 34 rotates to a horizontal state, the wing plate 35 returns to a vertical state. At this time, the wing plate 35 is fixed with the lock 39 again, and the upper part of the carriage 3 is closed. Then the door 33 is closed, thereby completing the overall closure of the carriage 3 to facilitate the transportation of cargo.

[0058] When the temperature of the solar photovoltaic panel 41 on the top plate 34 is too high during transportation, the interior of the carriage 3 needs to be cooled down. The two-way cylinder 528 is started to shrink the end on which the second limit block 527 is fixed, and the limit on the first rotating shaft 525 is released. The driving motor 521 is started, and the driving motor 521 drives the other end of the first connecting rod 523 to rotate downward. The first connecting rod 523 drives the top plate 34 to rotate downward around the second rotating shaft 529 through the second connecting rod 524. The supports 37 are arranged at intervals, so that the top plate 34 can be rotated to the end close to the beam 38 to abut against the support 37. At this time, the top plate 34 is in a downward tilted state close to the end of the beam 38. There is a gap between the top plate 34 and the support 37, and the top of the carriage 3 is opened. On the one hand, it is convenient for ventilation and heat dissipation in the carriage 3. On the other hand, the top plate 34 and the internal space of the carriage 3 are arranged at intervals, which reduces the heat conducted to the internal space of the carriage 3 by the solar photovoltaic panel 41 through the top plate 34, thereby cooling the internal space of the carriage 3.

[0059] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
