[0035] One preferred embodiment of the present application is shown as Figures 1 to 3 A new energy luggage towing vehicle includes a trailer head 1, a towing plate vehicle 2, a tensioning mechanism 4 and a monitoring module (not shown). A new energy battery (not shown) is installed inside the trailer head 1 to provide power for the whole luggage towing vehicle, and the new energy battery can also provide energy for other devices. The trailer head 1 is detachably connected with the towing plate vehicle 2, so that the driver can drive the towing plate vehicle 2 by driving the trailer head 1. The towing plate vehicle 2 is used to stack luggage 01 and is fixed by a fixing member 3 after stacking. The specific structure type of the fixing member 3 can be fixed net or rainproof cloth, which can be selected by the person skilled in the art according to the actual needs. The fixing member 3 can flexibly wrap the luggage stacked on the towing plate vehicle 2, and then fix the luggage by tensioning the fixing member 3. The tensioning mechanism 4 is installed at the bottom of the towing plate vehicle 2 and connected with the fixing member 3 through the output end. The tensioning mechanism 4 is drivingly connected with a power source (not shown) installed in the trailer head 1, and the power source is powered by the new energy battery. When the fixing member 3 needs to be tensioned, the power source can provide power for the tensioning mechanism 4, so as to drive the tensioning mechanism 4 to tension the fixing member 3 to a set value. The monitoring module is used to monitor the tension of the fixing member 3, and sends a tightening signal to the power source when the tension of the fixing member 3 does not meet the requirements, so that the tensioning mechanism 4 is tightened under the driving of the power source.

[0036] It can be understood that when the luggage 01 is stacked, due to the shape and size difference of the luggage 01, there may be gaps between the luggage 01. The fixing of the fixed part 3 to the stacked luggage 01 is carried out in a static state. When the entire luggage trailer travels, the stacked luggage 01 may change position under the bumping and / or acceleration / deceleration of the luggage trailer, that is, the gap between the luggage 01 may be eliminated, which causes the stacking space of the stacked luggage 01 to become smaller, so that under the tension of the fixed part 3, the luggage 01 may be scattered or dropped during travel due to insufficient fixing of the fixed part 3 to the luggage 01.

[0037] Therefore, in the present embodiment, a monitoring module can be provided to monitor the tension of the fixed part 3, that is, when the tension of the fixed part 3 is greater than or equal to a set value, it indicates that the position change of the luggage 01 on the towing board car 2 is small. When the tension of the fixed part 3 is less than the set value, it indicates that the luggage 01 on the towing board car 2 has a large position change, so that the luggage 01 will have a risk of falling. At this time, the monitoring module can control the power source to start according to the monitoring result, and then the power source drives the tensioning mechanism 4 to move under the power supply of the new energy battery, and then the tensioning mechanism 4 can drive the fixed part 3 to be tensioned, so as to ensure that the fixed part 3 can stably fix the luggage 01, thereby ensuring the transportation safety of the luggage 01. The specific structure and working principle of the monitoring module are known to those skilled in the art, so they will not be described in detail here; common monitoring module structures include force sensors and control units; the force sensor can be installed at the connection position of the tensioning mechanism 4 and the fixed part 3, for monitoring the tension of the fixed part 3; the control unit is signal connected with the force sensor and the power source, and the control unit controls the power source to perform corresponding actions according to the monitoring result of the force sensor.

[0038] In the present embodiment, as shown in Figure 1 and Figure 2 The towing board car 2 is provided with a plurality of towing board cars 2, which can be selected according to the number of luggage 01 to be transported. For the case of using multiple towing board cars 2, the multiple towing board cars 2 are connected in sequence and can be detached. Between the two adjacent towing board cars 2, the tensioning mechanism 4 of the previous towing board car 2 is connected with the power input end of the tensioning mechanism 4 of the next towing board car 2 through the power output end, so that the power source in the trailer head 1 simultaneously drives and controls the tensioning mechanism 4 of the multiple towing board cars 2.

[0039] It is necessary to know that when the luggage 01 is transported by the plurality of traction board cars 2, there is a situation that the tension of the fixing member 3 on some traction board cars 2 is insufficient, and the tension of the fixing member 3 on the remaining traction board cars 2 meets the requirements. In order to avoid the damage of the luggage 01 caused by the excessive tension of the fixing member 3, it is necessary to control the tension of the fixing member 3 which is insufficient, and the remaining fixing member 3 maintains the current tension. For the above functional requirements, the tensioning mechanism 4 can be used to achieve the function, and there are various specific structures of the tensioning mechanism 4 which can achieve the function. In order to facilitate understanding, one of the structures will be described in detail below.

[0040] In the embodiment, as shown in Figure 2 and Figure 3 , the tensioning mechanism 4 includes a transmission assembly 41, a traction assembly 42, and a transition assembly 43. The transmission assembly 41 is used for driving cooperation with a power source; the traction assembly 42 is provided with at least one and located at the side of the traction board car 2, for driving the fixing member 3 to be tensioned or relaxed. The transition assembly 43 is used for controlling the power transmission between the transmission assembly 41 and the traction assembly 42; the tensioning mechanisms 4 corresponding to the adjacent two traction board cars 2 are powered by the transmission assembly 41. When the monitoring module installed on the traction board car 2 detects that the tension of the corresponding fixing member 3 does not meet the requirements, the transition assembly 43 on the traction board car 2 transmits the power of the transmission assembly 41 to the traction assembly 42, so that the traction assembly 42 tensions the fixing member 3; at this time, the transition assemblies 43 on the remaining traction board cars 2 release the power transmission between the corresponding transmission assembly 41 and the traction assembly 42.

[0041] In order to facilitate understanding, two traction board cars 2 will be taken as an example below, wherein the traction board car 2 connected with the trailer head 1 can be defined as board car #1, and the other traction board car 2 can be defined as board car #2. The end of the transmission assembly 41 on the board car #1 close to the trailer head 1 is the power input end, and the other end is the power output end; the end of the transmission assembly 41 on the board car #2 close to the board car #1 is the power input end, and the other end is the power output end. The transmission assembly 41 on the board car #1 is in transmission cooperation with the power source on the trailer head 1 through the power input end, and the transmission assembly 41 on the board car #1 is in transmission cooperation with the power input end of the transmission assembly 41 on the board car #2 through the power output end.

[0042] At the beginning, after the luggage 01 is stacked on the two traction trolleys 2, the power source can drive the transmission assembly 41 on the trolley #1 and the transmission assembly 41 on the trolley #2 to operate synchronously, at this time, the traction assembly 42 on the two traction trolleys 2 is in transmission cooperation with the corresponding transmission assembly 41 through the transition assembly 43, and then the traction assembly 42 on the two traction trolleys 2 drives the corresponding fixed part 3 to tension the stacked luggage 01 until the tension of the fixed part 3 reaches the set value; at this time, the transition assembly 43 on the two traction trolleys 2 releases the power transmission between the corresponding transmission assembly 41 and the traction assembly 42; the traction assembly 42 can lock the tension of the fixed part 3.

[0043] During the driving of the luggage traction vehicle, if the tension of the fixed part 3 on the trolley #2 is reduced due to the change of the stacking space of the luggage 01, at this time, only the transition assembly 43 on the trolley #2 is needed to control the transmission assembly 41 and the traction assembly 42 to be in transmission connection, and then the transmission assembly 41 on the trolley #1 and the trolley #2 is driven to operate by the power source, then the traction assembly 42 on the trolley #2 will drive the corresponding fixed part 3 to be tensioned, and the traction assembly 42 on the trolley #1 will still keep the tension of the fixed part 3 locked.

[0044] After the luggage traction vehicle drives to the destination, the transition assembly 43 on the two traction trolleys 2 will again drive the transmission assembly 41 and the traction assembly 42 to be in transmission connection, so as to drive the corresponding traction assembly 42 to drive the fixed part 3 to be relaxed by the power source driving the transmission assembly 41 on the two traction trolleys 2, so as to facilitate the removal of the fixed part 3 for the transportation of the luggage 01. Based on the technical scheme of the present application, the tensioning and relaxing process of the fixed part 3 is realized automatically by the tensioning mechanism 4 and the driving of the power source, so as to effectively reduce the labor intensity. At the same time, the tension control of the fixed part 3 can be realized according to the monitoring module, and the tension of the fixed part 3 can be self-adapted to ensure the safety of the transportation of the luggage 01.

[0045] In the embodiment, the specific structure of the transmission assembly 41 has many kinds, in order to facilitate understanding, one specific example will be described in detail as follows. Figure 3 and Figure 4As shown, the front and rear ends of the traction board vehicle 2 are vertically rotatably installed with connecting shafts; the transmission assembly 41 includes a first transmission belt 411, a first gear 412 and a second gear 413. The two connecting shafts are connected through the first transmission belt 411, and the specific structure type of the first transmission belt 411 is various; if the first transmission belt 411 adopts a transmission chain, then chain wheels are installed on the two connecting shafts; if the first transmission belt 411 adopts a belt, then pulleys are installed on the two connecting shafts; if the first transmission belt 411 adopts a toothed belt, then gears are installed on the two connecting shafts; in order to ensure stable transmission, the first transmission belt 411 adopts a toothed belt in the embodiment. The first gear 412 is fixedly installed on the connecting shaft at the front end of the traction board vehicle 2, thereby forming a power input end, and the second gear 413 is fixedly installed on the connecting shaft at the rear end of the traction board vehicle 2, thereby forming a power output end. The transmission assembly 41 is in transmission connection with the transition assembly 43 through the first transmission belt 411 located at the middle position between the two connecting shafts.

[0046] It should be known that, as Figure 4 shown, the two adjacent traction board vehicles 2 are in meshing connection through the first gear 412 and the second gear 413, and then in order to ensure transmission adaptation, the power source and the transmission assembly 41 on the traction board vehicle 2 close to the trailer head 1 are also in meshing through the first gear 412 and the second gear 413. Specifically, the power source includes a motor installed in the trailer head 1, and the motor is powered by a new energy battery; the rear end of the trailer head 1 is also vertically rotatably installed with a connecting shaft, the output end of the motor is connected with the connecting shaft through a transmission structure, and the transmission structure can adopt gear transmission, belt transmission, chain transmission, etc.; the second gear 413 is fixedly installed on the connecting shaft at the rear end of the trailer head 1, and then the trailer head 1 can be in meshing with the first gear 412 installed on the connecting shaft at the front end of the connected traction board vehicle 2 through the second gear 413 on the connecting shaft at the rear end.

[0047] It should be noted that the trailer head 1 and the towing plate car 2 and the adjacent towing plate car 2 are connected by the vertical insertion of the pin shaft, so that the trailer head 1 and the towing plate car 2 and the adjacent towing plate car 2 can be easily disassembled; The specific connection method is known to those skilled in the art, so it will not be described in detail here. The connection position between the trailer head 1 and the towing plate car 2 and the adjacent towing plate car 2 and the installation position of the connecting shaft are coaxial, so that the angle change between the trailer head 1 and the towing plate car 2 and the adjacent towing plate car 2 due to the turning will not affect the meshing between the first gear 412 and the second gear 413; The angle change between the trailer head 1 and the towing plate car 2 and the adjacent towing plate car 2 can be equivalent to the circumferential rotation of one of the first gear 412 and the second gear 413 around the axis of the other gear. Since the distance between the first gear 412 and the second gear 413 does not change, the meshing between the first gear 412 and the second gear 413 remains stable.

[0048] In this embodiment, the fixing member 3 can be fixed by one side position, and the other side is moved by the traction assembly 42 to realize tensioning and loosening; That is, the tensioning mechanism 4 only includes one traction assembly 42 and a transition assembly 43, and is installed on one side of the bottom of the vehicle body 20 of the towing plate car 2. The fixing member 3 can also be moved by the traction of both sides to realize tensioning and loosening, that is, the tensioning mechanism 4 includes two traction assemblies 42 and two transition assemblies 43, and is respectively installed on both sides of the bottom of the vehicle body 20 of the towing plate car 2. The specific installation form of the fixing member 3 can be selected by those skilled in the art according to actual needs; In order to facilitate the description, the tensioning and loosening of the fixing member 3 through the traction of both sides is taken as an example.

[0049] In this embodiment, as shown in Figure 2 and Figure 5 The traction assembly 42 includes a rotating roller 423, a rotating shaft 422 and a traction member 421. The rotating shaft 422 is horizontally rotatably installed on one side of the bottom of the vehicle body 20 of the towing plate car 2, the rotating roller 423 is installed on the rotating shaft 422, and the traction member 421 is wound on the rotating roller 423 and is detachably fixedly connected with the fixing member 3 through the traction end 4211. The specific fixed connection method is known to those skilled in the art. The rotating shaft 422 can be in transmission cooperation with the transition assembly 43, so that the rotating shaft 422 drives the rotating roller 423 to rotate under the drive of the transition assembly 43, and then the winding and loosening of the traction member 421 by the rotating roller 423 drives the fixing member 3 to tension and loosen.

[0050] It should be known that the traction member 421 is a flexible structure, in order to ensure the stable connection of the traction member 421 and the fixing member 3, the traction end 4211 can be provided in plurality, and the plurality of traction ends 4211 can be arranged at equal intervals along the axis of the rotating roller 423. The fixing member 3 can be to cover the entire traction board vehicle 2, or a single traction board vehicle 2 can adopt multiple fixing members 3, for example Figure 2 As shown in the figure, the single traction board vehicle 2 adopts two fixing members 3, and the two fixing members 3 are respectively located at the front and rear positions of the traction board vehicle 2. The number of rotating rollers 423 is equal to the number of fixing members 3.

[0051] In the embodiment, as shown in the figure, Figure 5 The traction assembly 42 further comprises a torsion spring 424; the rotating roller 423 is rotatably installed on the rotating shaft 422, and the rotating roller 423 and the rotating shaft 422 are connected through the torsion spring 424; the torsion spring 424 can be in a deformed state when the traction member 421 drives the fixing member 3 to be tensioned. Specifically, the length of the rotating shaft 422 is greater than the length of the rotating roller 423, so that the two ends of the rotating shaft 422 pass through the two rotating rollers 423 on the two sides respectively. The torsion spring 424 is sleeved and installed on the end of the rotating shaft 422, one end of the torsion spring 424 is connected with the rotating shaft 422, and the other end is connected with the end of the rotating roller 423, so that when the rotating shaft 422 rotates, the torsion spring 424 can be driven to elastically deform first, and then the torsion spring 424 drives the rotating roller 423 to rotate through the deformation force. In order to ensure sufficient elastic force, the torsion spring 424 can be provided in plurality, for example Figure 5 As shown in the figure, the torsion spring 424 is installed on the two ends of the rotating shaft 422.

[0052] It can be understood that if the rotating roller 423 is fixedly connected with the rotating shaft 422, after the fixing member 3 is fixedly connected with the traction member 421, the fixing member 3 and the entire traction board vehicle 2 can be regarded as rigid connection. The set value of the tensioning force of the fixing member 3 for fixing the luggage 01 is generally a range value, that is, the tensioning force of the fixing value will cause the power source to frequently start and stop during the driving of the luggage traction vehicle, thereby reducing the service life of the power source. Then for the tensioning force in the range value, based on the bumping of the traction board vehicle 2 during the driving of the luggage traction vehicle, the tension of the traction member 421 on the fixing member 3 will fluctuate, which will cause the fixing member 3 to press the luggage 01 frequently, which is easy to cause the luggage 01 to have indentation. By elastically rotating the rotating roller 423 on the rotating shaft 422 through the torsion spring 424, when the traction board vehicle 2 bumps, the traction member 421 absorbs energy based on the elastic deformation of the torsion spring 424, thereby reducing the pressing damage of the fixing member 3 to the luggage 01.

[0053] In the embodiment, as shown in the figure, Figures 6 to 8As shown, the transition assembly 43 includes a transmission wheel 432, a clutch assembly, and a transmission shaft 431. The transmission shaft 431 is vertically rotatably mounted on the side of the body 20 of the traction vehicle 2. A worm gear section 4311 is provided at the lower part of the transmission shaft 431. A worm wheel 4221 is fixedly mounted in the middle of the rotating shaft 422 of the traction assembly 42. The transmission shaft 431 and the rotating shaft 422 are connected by a worm gear transmission via the worm wheel 4221 and the worm gear section 4311. The transmission wheel 432 is rotatably mounted on the upper part of the transmission shaft 431 via bearings, and it is connected to the first transmission belt 411 of the transmission assembly 41. The clutch assembly is mounted on the transmission shaft 431 and engages with it. The clutch assembly can be connected to or disconnected from the transmission wheel 432 under the control of the monitoring module.

[0054] It is understandable that when the first transmission belt 411 is a toothed belt, the transmission pulley 432 is a gear; since the installation position of the transmission shaft 431 is off-center from the center of the vehicle body 20, in order to ensure that the first transmission belt 411 and the transmission pulley 432 have a sufficient wrap angle, such as Figure 3 As shown, two pairs of guide wheels 414 need to be set at the center of the body 20 of the traction cart 2. The first transmission belt 411 cooperates with the transmission wheel 432 through the guide wheels 414 so that the wrap angle between the first transmission belt 411 and the transmission wheel 432 is greater than 120°, preferably greater than 150°.

[0055] The worm gear transmission between the drive shaft 431 and the rotating shaft 422 enables the traction assembly 42 to lock the tension of the fixed member 3. When the tension of the fixed member 3 meets the requirements, the clutch assembly disengages from the drive wheel 432, allowing the drive wheel 432 to idle under the drive of the transmission assembly 41. When the tension of the fixed member 3 does not meet the requirements, the clutch assembly engages with the drive wheel 432, and the drive wheel 432 connects to the drive shaft 431 via the clutch assembly, allowing the power of the transmission assembly 41 to be transmitted to the traction assembly 42 through the drive shaft 431. Various types of clutch assemblies can achieve the above functions. For ease of control by the monitoring module, an electromagnetic clutch assembly is preferred in this embodiment, which will be described in detail below.

[0056] Specifically, such as Figures 6 to 8As shown, the transmission shaft 431 is rotatably installed on the support seat 201 provided on the traction board vehicle 2; the clutch assembly comprises a coil module 434, a magnetic piece 4333 and a clutch sleeve 433. The clutch sleeve 433 is spline-connected with the first spline segment 4312 provided on the upper portion of the transmission shaft 431 through the spline groove 4331 provided at the center; the magnetic piece 4333 is fixedly provided inside the clutch sleeve 433 and magnetically cooperates with the coil module 434. The coil module 434 is fixedly installed on the support seat 201, and the coil module 434 can generate different-polarity magnetic force through power-on under the control of the monitoring module, thereby driving the clutch sleeve 433 provided with the magnetic piece 4333 to approach or move away from the transmission wheel 432; the clutch sleeve 433 is plug-connected with the transmission wheel 432 when approaching the transmission wheel 432.

[0057] It should be known that the specific structure and working principle of the coil module 434 are all known technologies of those skilled in the art, and therefore will not be described in detail here. The magnetic piece 4333 can be a magnet or an electromagnetic coil, and the specific selection can be made by those skilled in the art according to actual needs.

[0058] It can be understood that there are various plug structures of the clutch sleeve 433 and the transmission wheel 432, and one of the structures will be described in detail below for the convenience of understanding. Figures 6 to 8 As shown, the end face of the clutch sleeve 433 approaching the transmission wheel 432 is provided with a plurality of axially extending plug rods 4332 in the circumferential direction, and the end face of the transmission wheel 432 approaching the clutch sleeve 433 is provided with a plurality of axially extending plug grooves 4320 in the circumferential direction. As shown, Figure 7 At the initial time, as shown, the end face of the clutch sleeve 433 on the support seat 201 is opposite to the coil module 434, and at this time, the clutch sleeve 433 is spaced apart from the transmission wheel 432, so that the plug rod 4332 is separated from the plug groove 4320. Figure 8 As shown, the coil module 433 can generate magnetic force repelling the magnetic piece 4333 through power-on, and then the clutch sleeve 433 will approach the transmission wheel 432 under the action of the magnetic force; if the plug rod 4332 is opposite to the plug groove 4320 at this time, the plug rod 4332 can be plug-connected with the plug groove 4320; if the plug rod 4332 is misaligned with the plug groove 4320 at this time, the transmission wheel 432 can be rotated to a moment when the plug rod 4332 is opposite to the plug groove 4320 under the driving of the transmission assembly 41, at which time the clutch sleeve 433 can drive the plug rod 4332 to be plug-connected with the plug groove 4320 under the action of the magnetic force, and then the transmission wheel 432 drives the clutch sleeve 433 to rotate synchronously, and then the clutch sleeve 433 drives the transmission shaft 431 to rotate synchronously through the spline connection with the transmission shaft 431, so that the transmission shaft 431 drives the traction assembly 42 to tension or relax the fixing member 3. After the tensioning or relaxing of the fixing member 3 is completed, as shown, Figure 7As shown, the coil module 433 can be powered off, so that the clutch cover 433 is axially downward along the transmission shaft 431 under the action of gravity until the plug rod 4332 is disengaged from the plug slot 4320; or the coil module 433 can generate a magnetic force that attracts the magnetic part 4332, so that the clutch cover 433 is axially downward along the transmission shaft 431 under the combined action of gravity and magnetic force until the plug rod 4332 is disengaged from the plug slot 4320.

[0059] In this embodiment, as shown, Figure 9 As shown, the traction board car 2 is rotatably installed with a baffle 21 on both sides, and the baffle 21 can form a placing bin for stacking luggage 01 with the vehicle body 20 in a vertical state, and the baffle 21 can open the placing bin for carrying luggage 01 in a horizontal state. The traction board car 2 is installed with an opening and closing mechanism 5 on both sides to control the movement of the corresponding side baffle 21, and the opening and closing mechanism 5 includes a driving assembly 51, a control assembly 52, and a power interrupting assembly 53; the driving assembly 51 can drive the baffle 21 to move by rotating, and the driving assembly 51 and the tensioning mechanism 4 are connected through the power interrupting assembly 53. The control assembly 52 can drive the driving assembly 51 to move to a first position and a second position; the power interrupting assembly 53 can disconnect the driving transmission connection between the driving assembly 51 and the tensioning mechanism 4 when the driving assembly 51 is in the first position, and the power interrupting assembly 53 can drive the driving assembly 51 and the tensioning mechanism 4 to be in transmission connection when the driving assembly 51 is in the second position, so that the driving assembly 51 performs a rotating action under the drive of the tensioning mechanism 4.

[0060] It can be understood that the baffle 21 needs to be kept vertical during the movement of the traction board car 2, so the movement state of the baffle 21 is irrelevant to the tensioning of the fixing part 3 during the movement of the traction board car 2. Therefore, the tensioning mechanism 4 cannot be in transmission connection with the opening and closing mechanism 5 at all times, but only in transmission connection with the opening and closing mechanism 5 when specific work is needed. Generally, when carrying luggage 01, the traction board car 2 only needs to flatten the baffle 21 on one side, so by the setting of the control assembly 52, only the control assembly 52 on the corresponding side is controlled to move the driving assembly 51 to the second position, so that the driving assembly 51 on the corresponding side is in transmission connection with the tensioning mechanism 4, thereby controlling the movement of the baffle 21 on one side. In the technical solution of the present application, whether the baffle 21 moves or not can be realized by the control assembly 52, and whether the fixing part 3 is tensioned or not can be realized by the transition assembly 43, that is, the movement of the baffle 21 and the tensioning of the fixing part 3 do not interfere with each other; both can be performed synchronously or independently. At the same time, in this embodiment, the driving of the baffle 21 is also realized by a power source, without manual operation, but only the power transmission by manually driving the control assembly 52; thereby the labor intensity can be effectively reduced.

[0061] In the embodiment, as shown in Figure 9 and Figure 10 The driving assembly 51 comprises a driving shaft 511 and a connecting rod assembly. The driving shaft 511 is movably installed horizontally on the rotating seat 202 arranged on the side of the towing board vehicle 2. In order to ensure the stability of the installation of the driving shaft 511, a plurality of rotating seats 202 can be arranged. The driving shaft 511 cooperates with the control assembly 52 to move horizontally under the driving of the control assembly 52. The connecting rod assembly is arranged in plurality. The plurality of connecting rod assemblies are arranged at intervals along the axial direction of the driving shaft 511. One end of the connecting rod assembly is connected with the driving shaft 511 by means of spline connection. The other end of the connecting rod assembly is hingedly connected with the baffle 21. The connecting rod assembly drives the baffle 21 to rotate around the installation position under the rotation of the driving shaft 511.

[0062] It can be understood that the specific structure of the connecting rod assembly is known to those skilled in the art. As shown in Figure 10 The connecting rod assembly comprises a connecting rod 513 and a crank 512. The crank 512 is connected with the second spline section 5111 arranged on the driving shaft 511 by means of spline connection through the connecting sleeve 5121 arranged on the first end of the crank 512. The crank 512 is driven to rotate synchronously under the rotation of the driving shaft 511. At the same time, the driving shaft 511 can also move horizontally relative to the crank 512. The connecting rod 513 is hingedly installed on the baffle 21 through the first end. The second end of the connecting rod 513 is hingedly connected with the second end of the crank 512. Thus, the connecting rod 513 drives the baffle 21 to rotate around the installation position under the rotation of the crank 512. In order to ensure the stability of the support of the baffle 21, the crank 512 and the connecting rod 513 are in parallel state when the baffle 21 is in vertical state. That is, the crank 512 and the connecting rod 513 form a dead point at this time.

[0063] In the embodiment, the specific structure of the control assembly 52 capable of driving the driving shaft 511 to move horizontally is various. In order to facilitate understanding, one specific structure will be described in detail below. As shown in Figure 11 The driving assembly 51 further comprises a first spring 514. The first spring 514 is sleeved on the driving shaft 511. The driving shaft 511 and the rotating seat 202 are axially elastically connected through the first spring 514. The control assembly 52 comprises a cam sleeve 521. The cam sleeve 521 is rotatably installed on the first mounting seat 203 arranged on the side of the towing board vehicle 2. The cam sleeve 521 is located at the end of the driving shaft 511 and is coaxial with the driving shaft 511. The cam sleeve 521 is cammed with the cam end 522 arranged at the end of the driving shaft 511. The end of the cam sleeve 521 away from the driving shaft 511 is provided with a handle 5211.

[0064] At the beginning, the cam sleeve 521 is in contact with the cam surface of the cam end 522 of the driving shaft 511, and the first spring 514 is in a natural state or a small deformation state. At this time, the driving shaft 511 is in the first position, that is, the driving shaft 511 is disengaged from the power intermittent assembly 53. At this time, the baffle 21 is in a vertical state.

[0065] When it is needed to move the baffle 21 from the vertical state to the horizontal state, the handle 5211 can be rotated to make the cam sleeve 521 in cam cooperation with the cam end 522 of the driving shaft 511, so that the driving shaft 511 moves horizontally away from the cam sleeve 521 until the driving shaft 511 moves to the second position; at this time, the cam sleeve 521 is flush with the end surface of the cam end 522, and the first spring 514 is in a large deformation state. Then the driving shaft 511 is in transmission connection with the tensioning mechanism 4 through the power intermittent assembly 53, so that the driving shaft 511 can drive the connecting rod assembly to drive the baffle 21 to move to the horizontal state.

[0066] After the luggage 01 is carried, the tensioning mechanism 4 can be controlled to drive the driving shaft 511 to rotate reversely, so that the baffle 21 is rotated from the horizontal state to the vertical state again. Although only the handle 5211 needs to be rotated to the initial position, during the rotation of the handle 5211, the driving shaft 511 can be moved to the first position again under the reset elastic force of the first spring 514, so that the cam sleeve 521 is in contact with the cam surface of the cam end 522 again.

[0067] It should be noted that the rotation angle of the crank 512 is less than 180° during the rotation of the baffle 21 from the vertical state to the horizontal state, so the relative rotation angle of the cam sleeve 521 and the end surface of the cam end 522 after being flush is less than 180°, and in order to ensure that the cam sleeve 521 and the end surface of the cam end 522 do not affect the rotation of the driving shaft 511, it is necessary to ensure that the cam surface of the cam sleeve 521 corresponds to an angle less than 180°.

[0068] It should also be noted that, in the process of camming the cam sleeve 521 and the cam end 522, the drive shaft 511 cannot rotate, otherwise the drive shaft 511 will not be able to move axially; and after the cam sleeve 521 and the cam end 522 are completed camming, the drive shaft 511 needs to be rotated. Therefore, a limiting structure can be provided between the drive shaft 511 and the corresponding rotating seat 202, which can be a limiting block provided on the drive shaft 511 and a limiting groove provided on the rotating seat 202; the cooperation length of the limiting block and the limiting groove is the distance between the first position and the second position, so that when the drive shaft 511 is in the first position, the limiting block and the limiting groove are in a cooperating state, at this time the drive shaft 511 cannot be rotated, and at the same time it can also ensure that the connecting rod assembly supports the baffle 21 stably; and when the drive shaft 511 moves to the second position, the limiting block and the limiting groove are disengaged, at this time the drive shaft 511 is in a free state in the circumferential direction.

[0069] In this embodiment, as shown in Figure 12 The power interrupting assembly 53 includes a rotating sleeve 533 movably sleeved on the drive shaft 511, a friction sleeve 534, and a second spring 535. The rotating sleeve 533 is rotatably installed on the second mounting seat 204 of the side of the traction board vehicle 2, and the rotating sleeve 533 is in transmission cooperation with the tensioning mechanism 4. The friction sleeve 534 is slidably sleeved and installed on the drive shaft 511, and the second spring 535 is sleeved and installed on the drive shaft 511. One end of the second spring 535 is connected with the stop block 5112 provided on the drive shaft 511, and the other end of the second spring 535 is connected with the friction sleeve 534, so that the friction sleeve 534 is axially elastically slidably installed on the drive shaft 511 through the second spring 535. When the drive shaft 511 is located at the first position, the friction sleeve 534 is spaced from the rotating sleeve 533; when the drive shaft 511 is located at the second position, the friction sleeve 534 is in friction or plug-in cooperation with the rotating sleeve 533, and then the rotating sleeve 533 drives the drive shaft 511 to rotate under the drive of the tensioning mechanism 4.

[0070] It can be understood that there are various specific connection modes between the rotating sleeve 533 and the tensioning mechanism 4. In order to facilitate understanding, one specific structure will be described in detail below. As shown in Figure 6 、 Figure 7 and Figure 12As shown, the top end of the transmission wheel 432 is also provided with a bevel gear segment 4321, and the power interruption assembly 53 further comprises a bevel gear 531 and a second transmission belt 532. The bevel gear 531 is horizontally rotatably installed on the bottom of the towing board vehicle 2 through a connecting shaft and is in mesh with the bevel gear segment 4321 at the top end of the transmission wheel 432. The connecting shaft on which the bevel gear 531 is installed and a rotating sleeve 533 are drivingly connected through the second transmission belt 532. If the second transmission belt 532 is a belt, corresponding belt pulleys are provided on the connecting shaft and the rotating sleeve 533; if the second transmission belt 532 is a transmission chain, corresponding sprockets are provided on the connecting shaft and the rotating sleeve 533; if the second transmission belt 532 is a toothed belt, corresponding gears are provided on the connecting shaft and the rotating sleeve 533. The specific structural form of the second transmission belt 532 can be selected by those skilled in the art according to actual needs, and in the embodiment, a toothed belt is preferably used.

[0071] The above describes the basic principles, main features and advantages of the present application. Those skilled in the art should understand that the present application is not limited to the above embodiments, and the above embodiments and descriptions in the specification are only the principles of the present application. Without departing from the spirit and scope of the present application, various changes and improvements can be made to the present application, and these changes and improvements all fall within the scope of the claimed present application.
