Since it is convenient for loading and unloading goods, this type of truck is often used in logistics transportation. In the related art, a Chinese utility model patent with the authorization publication number CN207106196U discloses a new energy logistics transport vehicle, which includes a cargo box, 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, a hydraulic cylinder is 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 of the cargo box, a solar photovoltaic panel is installed on the first side panel, the second side panel and the top panel, and a solar controller, a battery pack, an inverter and a 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 motor, and the motor is used to drive the logistics transport vehicle to move.

The electricity generated by the solar photovoltaic panel can be stored in a battery pack or used by an electric motor.

[0003] With respect to 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 absorb and convert light energy better, 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 also 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

[0035] Reference Figure 1 and Figure 2The main driving mechanism 5 includes a fixed box 51 and two sets of driving components 52. The two sets of driving components 52 are used to drive the two top plates 34 to rotate. The fixed box 51 is fixedly connected to the side of the support 37 away from the cross beam 38. The length direction of the fixed box 51 is parallel to the length direction of the support 37. The fixed box 51 is opened on the side facing the cross beam 38 and at both ends. For drainage, grooves are provided at both ends of the bottom surface of the fixed box 51 for drainage. The two sets of driving components 52 are arranged in the fixed box 51 and are arranged relative to each other with the vertical plane where the axis of the cross beam 38 is located as the symmetric plane. The driving assembly 52 includes a driving motor 521, which is installed on the inner bottom wall of the fixed box 51. A driving shaft 522 is inserted and fixedly connected to the top plate 34.

The driving shaft 522 is located in the middle position in the width direction of the top plate 34. The axial direction of the driving shaft 522 is parallel to the axial direction of 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.

[0036] 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 cross beam 38. The side of the top plate 34 abutting the cross beam 38 is set to be arc-shaped for easy rotation. A first limit block 526 is fixedly connected to the top wall inside the fixed box 51. The first limit block 526 is located above the first rotating shaft 525, and a semicircular first limit groove 5261 is opened on the bottom surface of the first limit block 526. The first rotating shaft 525 is coaxially rotatably connected in the first limit 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 has a telescopic 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 under 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 away from the opening on the side of the two-way cylinder 528. When the telescopic shaft of the two-way cylinder 528 fixing the second limit block 527 is contracted, 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.

[0037] 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 door 33, and the two ends of the wing plate 35 are locked with the front plate 32 and the door 33 respectively through the lock 39. When the carriage 3 needs to be opened, the wing panel 35 needs to be opened and the two-way cylinder 528 is started. One end of the two-way cylinder 528 with the second limit block 527 fixed thereon extends in the direction close to the first limit block 526. When it moves to 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 panel 35. The driving motor 521 drives the other end of the first connecting rod 523 to rotate upward, and 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, and the top plate 34 drives the wing panel 35 to move upward. Since the top plate 34 and the wing panel 35 are rotatably connected, in the process of the top plate 34 driving the wing panel 35 to move upward, the wing panel 35 is always kept in a hanging state due to gravity, which can save space, thereby facilitating opening in different occasions and improving the applicability of the wingspan vehicle. When the wing plate 35 moves upward until its bottom is located at the support 37, the carriage 3 can be fully opened to facilitate loading and unloading of goods.

[0038] Reference Figure 2 and Figure 3 In order to facilitate closing the carriage 3, that is, it is necessary to lower the wing panel 35, a support block 530 is hinged on the other telescopic shaft of the two-way cylinder 528. When the wing panel 35 is lowered, the driving motor 521 is reversed, and the top plate 34 is driven to rotate downward through the first connecting rod 523 and the second connecting rod 524, and the top plate 34 drives the wing panel 35 to move downward. At this time, one end of the two-way cylinder 528 provided with the support block 530 is extended to abut against the side of the wing panel 35 facing the top plate 34, thereby supporting the wing panel 35 and opening the wing panel 35 to prevent the wing panel 35 from colliding with the goods during the downward movement. When the top plate 34 rotates to a horizontal state, the wing panel 35 returns to a vertical state. At this time, the wing panel 35 is fixed with the lock buckle 39, thereby completing the closure of the carriage 3 for easy transportation of goods.

[0039] 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 shrinks, releases the limit on the first rotating shaft 525, starts the driving motor 521, 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 with the second rotating shaft 529 as the center through the second connecting rod 524. Since the top plate 34 and the support 37 are spaced apart, the top plate 34 can be rotated to the end close to the cross beam 38 and abut against the support 37. At this time, the top plate 34 is in a state of being tilted downward at the end close to 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 to ventilate and dissipate heat in the carriage 3. On the other hand, the top plate 34 and the internal space of the carriage 3 are spaced apart to reduce the heat transmitted 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.

[0040] Reference Figure 4 In order to prevent rain from seeping into the gap between the top plate 34 and the support 37, a sealing plate 531 is provided between the top plate 34 and the support 37. A slide groove 371 is provided on the top of the support 37 along its length direction. The sealing plate 531 slides vertically in the slide groove 371. A plurality of supporting springs 532 are fixedly connected between the bottom surface of the sealing plate 531 and the bottom wall of the slide groove 371. When the top plate 34 is horizontally arranged, the supporting springs 532 support the sealing plate 531 to abut against the top plate 34, thereby sealing the interior of the carriage 3 to prevent rain from seeping in. When the top plate 34 rotates downward, the sealing plate 531 can be pushed into the slide groove 371, thereby making the top plate 34 and the support 37 spaced apart to facilitate ventilation in the carriage 3. The sealing plates 531 of the two sets of driving components 52 are respectively located on both sides of the length direction of the crossbeam 38.

[0041] 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 symmetry plane. One end of the first connecting rod 523 of the slave drive mechanism 6 is rotatably connected to the support 37 on the top of the door 33. Except that the slave drive mechanism 6 does not have a drive motor 521, the other structures are consistent with those of the main drive mechanism 5 and are not repeated here.

[0042] Reference Figure 5The top surface of the top plate 34 is fixedly connected to a limiting rod 42 near one side of 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 a silicone strip 44 is fixedly connected to the fixing plate 43 toward the side of 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.

[0043] Reference Figure 2 , Figure 5 and Figure 6 The wiping assembly 7 includes a sliding motor 71, a lead screw 72, a water pump 741 and two water spray pipes 76. A water collecting trough 73 is opened on the top surface of the beam 38 along its length direction. The lead screw 72 is rotatably connected in the water collecting trough 73. The axial direction of the lead 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 with the lead screw 72. The sliding motor 71 is used to drive the lead screw 72 to rotate. A slide seat 75 is slidably connected in the water collecting trough 73. The slide seat 75 is threadedly connected to the lead screw 72, and the water pump 741 is installed on the slide seat 75. The water inlet of the water pump 741 is connected with a water pump pipe 742, the mouth of the water pump pipe 742 faces downward, the water outlet of the water pump 741 is connected with a three-way pipe 743, and two water spray pipes 76 are connected with the water outlet of the water pump 741 through the three-way pipe 743. The two water spray pipes 76 are respectively located above the two top plates 34. The water spray pipe 76 includes a fixedly connected water spray hose 761 and a water spray hard pipe 762. The water spray hose 761 is connected with the three-way pipe 743, and the water spray hard pipe 762 is slidably connected above the top plate 34. The wing plate 35 is provided with a guide groove 352 along its length direction on the side facing the top plate 34, and the end of the water spray hard pipe 762 away from the water spray hose 761 is slidably connected in the guide groove 352. The water spraying hard pipe 762 is evenly provided with a plurality of water spraying holes 763 on the side facing the compartment door 33. A wiping sponge 77 is fixedly connected to the side of the water spraying hard pipe 762 facing the solar photovoltaic panel 41. The wiping sponge 77 is located on the side of the water spraying hole 763 away from the compartment door 33. In order to prevent rainwater from entering the compartment 3 from between the top plate 34 and the cross beam 38, a rainproof film 78 is bonded between the two top plates 34 and the cross beam 38, thereby preventing rainwater from entering the compartment 3.

[0044] 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 two water spray pipes 76. The water spray pipes 76 spray water to 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 seat 75 to slide in the direction close to the door 33. The slide seat 75 drives the two water spray pipes 76 to slide in the direction close to 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 in the back, 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 compartment 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.

[0045] 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 to below the first limit block 526, the first rotating shaft is limited. At this time, the driving motor 521 is started, the lock 39 on the wing plate 35 is opened, and the driving motor 521 drives the other end of the first connecting rod 523 to rotate upward, and 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, and 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, and the side panel 36 is flipped down, and the lower part of the carriage 3 is opened; then the compartment door 33 is opened, so that the carriage 3 is opened as a whole.

[0046] When it is necessary to close the carriage 3, first flip up the side panel 36 and fix it with the lock 39, and the lower part of the carriage 3 is closed. Then start the drive motor 521, and the drive motor 521 reverses, 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 opening the wing plate 35 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, 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.

[0047] 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 bidirectional cylinder 528 is started to shrink one end of the second limit block 527, release the limit on the first rotating shaft 525, start the driving motor 521, 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 with the second rotating shaft 529 as the center 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 at the end close to 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 an interval, 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.

[0048] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
