The method for controlling the tail board of the carriage can be applied to the terminal, and can be specifically executed by hardware or software in the terminal.

The carriage provided by the embodiment of the application is described below.

As shown in fig. 1 and 2, the vehicle cabin includes:

the box body 110, the opening of the box body 110 is provided with a tail plate surface 120, a tail plate lifting mechanism and a cover driving mechanism, the box body 110 is connected with the tail plate surface 120 through the tail plate lifting mechanism and the cover driving mechanism, the tail plate lifting mechanism is used for controlling the tail plate surface 120 to lift or descend, and the cover driving mechanism is used for controlling the tail plate surface 120 to cover the opening of the box body 110;

the sensor group is arranged at the opening of the carriage body 110 and comprises a first contact sensor 131 and a second contact sensor 132 which are arranged along two opposite sides intersecting with the running direction of the vehicle, the first contact sensor 131 is used for contacting with the tail plate lifting mechanism of the carriage, and the second contact sensor 132 is used for contacting with the tail plate surface 120 of the carriage;

And the tail plate controller is in communication connection with the first contact sensor 131 and the second contact sensor 132, is electrically connected with the tail plate lifting mechanism and the cover driving mechanism, and is used for controlling at least one action of the tail plate lifting mechanism or the cover driving mechanism of the tail plate surface 120 based on at least one of speed information of a vehicle where a carriage is located, tail plate control signals of the vehicle and signals of a sensor group.

It should be understood that the vehicle may be a train, an automobile, a passenger car, a truck, a van, or a vehicle with loading requirements such as an ambulance or a fire truck, and the following embodiments are all described by taking the van with the carriage as an example, which is not considered to limit the protection scope of the present application.

The carriage is a main part of the truck and used for loading cargoes, the shape and the size of the carriage can be adjusted according to the type and the number of the transported cargoes, and the type of the carriage of the truck can flexibly select closed type or semi-closed type according to the cargoes transported according to the needs.

The carriage comprises a carriage body 110, a first contact sensor 131 and a second contact sensor 132, wherein the carriage body 110 is a carrier for loading and transporting cargoes by a truck, the carriage body 110 can be of a cuboid structure formed by steel or other metal materials, and an opening can be formed in the side face or the tail end of the carriage body 110, so that the cargoes can be conveniently loaded and unloaded.

The opening part of the carriage body 110 is provided with a tail board surface 120, the tail board surface 120 can be an anti-slip metal plate, and the cargo in the carriage body 110 is prevented from falling off in the freight transportation process by covering the opening of the carriage body 110.

It should be noted that, the tailgate board 120 may be fixed at the opening of the carriage 110 by a tailgate lifting mechanism and a closing driving mechanism, and the tailgate board 120 may also be fixed on the frame 210 at the bottom of the truck by a tailgate lifting mechanism, a closing driving mechanism and a tailgate bracket 160.

The tailgate lifting mechanism is used to support and control movement of the tailgate panel 120 in a vertical direction, and may be a hydraulic system or an electric system.

The hydraulic system pushes hydraulic oil into the hydraulic cylinder through the hydraulic pump, so that the tail board surface 120 is lifted, and the electric system drives the tail board surface 120 to lift through the electric motor.

The cover driving mechanism can be used for driving the tail board surface 120 to rotate along the axial direction, so as to realize that the tail board surface 120 covers the opening of the carriage body 110.

The cover driving mechanism can be a screw transmission mechanism, an air cylinder driving mechanism, a hydraulic cylinder driving mechanism, a motor driving mechanism or a chain transmission mechanism and the like.

It should be noted that, unlike the existing scheme of setting the sensor on the tail board surface 120, the sensor group is set at the opening of the carriage body 110, and the carriage body 110 is of a relatively fixed structure, so that the sensor group fixed at the opening of the carriage body 110 has higher stability and detection precision, is convenient for later maintenance and calibration, can also avoid the collision or damage of the sensor group in the process of using the tail board surface 120, improves the safety of the sensor group, reduces the friction and vibration between the sensor group and the goods in the loading process of the goods, prolongs the service life of the sensor group, and improves the reliability and stability of the sensor group.

It will be appreciated that at least one action includes driving the tailgate lifting mechanism to control the tailgate panel 120 to lift or lower, and driving the closing driving mechanism to control the tailgate panel 120 to close or open.

As shown in fig. 3 and fig. 4, the first contact sensor 131 is used for contacting with the tail board lifting mechanism, so that the lifting state of the tail board surface 120 can be monitored in real time, the first contact sensor 131 can be one or more contact sensors, both of which are arranged at the bottom of the opening of the carriage body 110, and the first contact sensor 131 can contact with the tail board lifting mechanism when the tail board lifting mechanism lifts the tail board surface 120 until the bottom of the tail board surface 120 is flush with the bottom of the opening of the carriage body 110.

As shown in fig. 5 and 6, the second contact sensor 132 is configured to contact the tailgate board 120, so as to monitor the closing state of the tailgate board 120 in real time, where the second contact sensor 132 may be one or more contact sensors, both of which are disposed at the top of the opening of the carriage 110, and the second contact sensor 132 may contact the tailgate board 120 when the tailgate board 120 completely closes the opening of the carriage 110.

The first and second contact sensors 131 and 132 may be capacitive touch sensors, resistive touch sensors, surface acoustic wave sensors, or the like.

The tail board controller is used for receiving the signals of the first contact sensor 131 and the signals of the second contact sensor 132 and controlling the actions of the tail board lifting mechanism and the cover driving mechanism on the tail board surface 120.

The tailgate controller may be a programmable logic controller (Programmable Logic Controller, PLC) or a distributed control system (Distributed Control System, DCS) controller, or the like.

In actual execution, the tailgate controller receives the vehicle speed information of the truck, the control signal of the tailgate of the vehicle, and the signals of the first contact sensor 131 and the second contact sensor 132 in real time.

Under the condition that the truck is driven at a medium speed or at a high speed according to the vehicle speed information, if the signal of the first contact sensor 131 indicates that the tail lifting mechanism is not contacted with the first contact sensor 131, the tail lifting mechanism is driven to lift or descend until the received signal of the first contact sensor 131 indicates that the tail lifting mechanism is contacted with the first contact sensor 131.

If the signal of the second contact sensor 132 indicates that the tailgate board 120 and the second contact sensor 132 are not in contact, the driving and capping driving mechanism controls the tailgate board 120 to perform the capping action until the received signal of the second contact sensor 132 indicates that the tailgate board 120 is in contact with the second contact sensor 132, and at this time, the tailgate board 120 completely caps the opening of the carriage 110, which can avoid the risk of dropping the cargo or damaging the vehicle during the driving process due to the unclosed tailgate board 120.

In the embodiment of the application, the linkage of the tail board panel 120 and the vehicle speed information can be realized by neglecting the tail board control signal in the middle speed driving or the high speed driving of the truck, so that the risk that the tail board panel 120 is opened and cargoes fall due to misoperation in the middle speed driving or the high speed driving of the truck by personnel is avoided.

It will be appreciated that the tailgate control signal may be used to instruct actuation of the tailgate lifting mechanism or the closing drive mechanism to thereby control the tailgate panel 120 to perform a corresponding action.

Under the condition that the tail board controller determines that the truck is in a low-speed driving or non-driving state according to the vehicle speed information, the tail board controller drives the tail board lifting mechanism or the cover driving mechanism to control the tail board surface 120 to execute corresponding actions according to the tail board control signal.

The existing carriage is operated by a person manually to execute the action of the tail board, misoperation is easy to occur, the tail board is not lifted possibly due to negligence of an operator, the vehicle is run in a trade mode when the board surface of the tail board is not closed, a rear object is easy to collide during reversing, and goods are easy to throw out of the carriage due to inertia during advancing, so that serious safety accidents are caused.

For example, if the hydraulic tail board is closed under the lifting and descending state, the tail board is turned over to the ground directly, so that accidents occur.

According to the carriage provided by the embodiment of the application, the sensor groups arranged on the two opposite sides of the opening of the carriage body 110 can sense the contact state between the tail plate lifting mechanism and the tail plate surface 120, so that the action of the tail plate lifting mechanism or the cover driving mechanism is controlled, the carriage has higher fault tolerance and stability, the damage of the carriage body 110 and the tail plate surface 120 caused by the extrusion between the carriage body 110 and the tail plate surface 120 can be avoided, the control of the tail plate surface 120 is realized with lower cost through the linkage between the speed information and the control of the tail plate surface 120, the safety accident caused by the fact that the tail plate surface 120 is not covered in the vehicle driving process due to misoperation of personnel can be avoided, and the safety of the vehicle in the driving process is improved.

In some embodiments, the tail board lifting mechanism includes a lifting arm 141 and a lifting support rod 142, the lifting arm 141 has a constant length and is close to the carriage 110, the lifting support rod 142 is of a telescopic structure, and the lifting support rod 142 is controlled by the tail board controller to drive the tail board surface 120 to lift or descend;

the first contact sensor 131 is for contact with the lifting arm 141.

The lifting arms 141 are rotatable with a constant length and have high strength mechanical properties for supporting and stabilizing the tailgate surface 120, and at least two lifting arms 141 with equal length may be provided for stability of the tailgate surface 120, and the lifting arms 141 are uniformly distributed at the bottom of the opening of the carriage 110.

As shown in fig. 7 and 8, the tail board panel 120 is rotatably connected to the tail board bracket 160 through the lifting arm 141, the position of the tail board bracket 160 is not changed during the lifting or lowering process of the tail board panel 120, and the lifting arm 141 is used for supporting and stabilizing the tail board panel 120, so that the lifting process of the tail board panel 120 by the lifting support rod 142 is stable and reliable.

It should be noted that, one end of the lifting arm 141 is connected to the tail board bracket 160, and the other end is connected to the tail board surface 120, and the tail board bracket 160 can provide support for the lifting arm 141.

It can be appreciated that the lifting stay bar 142 may be a stay bar structure with a telescopic length, including a plurality of sections of telescopic pipes or rods, and the lifting stay bar 142 may adjust the length according to the control of the tail board controller, so as to achieve lifting or lowering of the tail board surface 120, which has flexibility and convenience.

The tail plate bracket 160 is connected to one end of the lifting stay 142, and the tail plate 120 is connected to the other end of the lifting stay 142, and the tail plate bracket 160 can provide support for the lifting stay 142, so that the expansion and contraction amount of the lifting stay 142 can fully act on the lifting of the tail plate 120.

In actual execution, if the first contact sensor 131 is disposed at the bottom of the opening of the carriage 110, when the lifting arm 141 contacts the first contact sensor 131, the bottom of the tailgate panel 120 is flush with and attached to the bottom of the opening of the carriage 110, and at this time, the tailgate controller determines that the lifting arm 141 contacts the first contact sensor 131 according to the signal of the first contact sensor 131, and controls the lifting brace 142 to stop stretching.

In this embodiment, lifting or lowering of the tail board panel 120 is achieved through expansion and contraction of the lifting stay bars 142, and the tail board panel 120 is supported and stabilized by using the lifting arms 141, so that lifting or lowering of the tail board panel 120 is stable and reliable, contact with the lifting arms 141 is sensed by the first contact sensor 131, extrusion between the tail board panel 120 and the carriage 110 can be avoided, and safety is improved.

In some embodiments, the capping driving mechanism includes a capping brace 150, the capping brace 150 is a telescopic structure, and the capping brace 150 is controlled by a tailgate controller to drive the tailgate panel 120 to open or close the opening of the carriage 110.

It can be appreciated that the covering brace 150 may be a brace structure with a telescopic length, including a plurality of sections of telescopic pipes or rods, and the covering brace 150 may adjust the length according to the control of the tailgate controller, so as to cover or open the opening of the tailgate panel 120 to the carriage 110, which has flexibility and convenience.

As shown in fig. 7 and 8, one end of the cover stay 150 is connected to the tail plate bracket 160, and the other end is connected to the tail plate surface 120, and the tail plate bracket 160 can provide support for the cover stay 150, so that the expansion and contraction amount of the cover stay 150 can completely act on the opening or closing of the opening of the carriage body 110 by the tail plate surface 120.

In actual implementation, if the second contact sensor 132 is disposed at the top of the opening of the carriage 110, when the tailgate board 120 contacts the second contact sensor 132, the top of the tailgate board 120 is flush with and attached to the top of the opening of the carriage 110, and at this time, the tailgate controller determines that the tailgate board 120 contacts the second contact sensor 132 according to the signal of the second contact sensor 132, and controls the closing brace 150 to stop stretching.

In addition, when cargo handling is required to be performed on the carriage 110, the tailgate controller can control the tailgate panel 120 to be opened and lowered, and a loading person can perform cargo handling through the tailgate panel 120, so that cargo handling efficiency can be improved, labor cost can be reduced, and safety of cargo in the handling process can be ensured.

In this embodiment, the tailgate controller senses the contact with the tailgate panel 120 through the second contact sensor 132, and controls the driving of the tailgate panel 120 by the closing stay 150, so that the extrusion between the tailgate panel 120 and the carriage 110 can be avoided, and the safety is improved.

In some embodiments, the tailgate controller is communicatively coupled to a lift switch and a close switch of the vehicle, the lift switch is configured to send a lift control signal or a drop control signal to the tailgate controller, and the close switch is configured to send a close control signal or an open control signal to the tailgate controller.

The vehicle may be provided with a lifting switch and a closing switch, for example, a button, or the lifting switch and the closing switch may be provided in an independent terminal device, for example, the lifting switch and the closing switch are provided in an Application (App) or an applet of a mobile phone, and after the mobile phone establishes communication connection with the tailgate controller, a user sends a lifting control signal, a lowering control signal, a closing control signal or an opening control signal to the tailgate controller through the lifting switch and the closing switch in the App or the applet of the mobile phone.

It can be understood that the tail board controller is in communication connection with the lifting switch and the closing switch, and is configured to receive a lifting control signal or a lowering control signal sent by the lifting switch, drive the lifting stay 142 to stretch and retract, control the tail board surface 120 to lift or descend, and is also configured to receive a closing control signal or an opening control signal sent by the closing switch, drive the closing stay 150 to stretch and retract, and control the tail board surface 120 to close or open.

As shown in fig. 9 and 10, the tailgate control signal is executed in the case where the tailgate controller determines that the truck is in a low-speed driving or non-driving state based on the vehicle speed information.

In the case that the tail board controller receives the lifting control signal of the lifting switch, the lifting supporting rod 142 is driven to stretch and retract, and the tail board surface 120 is controlled to lift until the received signal of the first contact sensor 131 indicates that the lifting arm 141 contacts the first contact sensor 131.

In the case where the tailgate controller receives a lowering control signal of the lift switch, the lift stay 142 is driven to expand and contract, and the tailgate panel 120 is controlled to descend until a signal indicating that the driving is stopped, which is sent by the lift switch, is received, or until the lift stay 142 expands and contracts to a defined length.

Under the condition that the tail board controller receives the closing control signal of the closing switch, the closing supporting rod 150 is driven to stretch and retract, and the tail board surface 120 is controlled to cover the opening of the carriage body 110 until the received signal of the second contact sensor 132 indicates that the tail board surface 120 contacts the second contact sensor 132.

In this embodiment, the control signals of the tail board lifting mechanism and the cover driving mechanism are received by the tail board controller, so that the tail board surface 120 is lifted or lowered, covered or opened, and the lifting switch and the cover are independently controlled, so that the tail board surface 120 is suitable for multiple application scenarios.

The embodiment of the application also provides a control method of the tail board of the carriage, which is applied to the carriage of each embodiment.

The execution main body of the method for controlling the tail board of the carriage provided by the embodiment of the application can be electronic equipment or a functional module or a functional entity capable of realizing the method for controlling the tail board of the carriage in the electronic equipment, and the method for controlling the tail board of the carriage provided by the embodiment of the application is described below by taking the electronic equipment as the execution main body as an example.

As shown in fig. 11, the method for controlling the tailgate of the vehicle compartment includes: step 1110 and step 1120.

Step 1110, obtaining speed information of a vehicle in which a carriage is located, a tail board control signal of the vehicle and a signal of a sensor group.

Wherein, the carriage body 110 opening of carriage is equipped with the sensor group, and the sensor group includes along crossing first contact sensor 131 and the second contact sensor 132 that set up in the opposite both sides of vehicle travel direction, and first contact sensor 131 is used for contacting with the tailboard lifting mechanism of carriage, and second contact sensor 132 is used for contacting with the tailboard face 120 of carriage.

Wherein the tail plate lifting mechanism includes a lifting stay 142.

As shown in fig. 12, an execution main body of the method for controlling the tail board of the carriage provided by the application may be a tail board controller, the tail board controller may be connected with a vehicle body controller, and may be connected with a lifting switch and a closing switch, and may be used for receiving a lifting control signal or a lowering control signal sent by the lifting switch, and receiving a closing control signal or an opening control signal sent by the closing switch.

The tailgate controller is also connected to the first and second contact sensors 131 and 132, and receives signals of the first and second contact sensors 131 and 132.

Step 1120, controlling at least one of the tail board lifting mechanism or the cover driving mechanism of the tail board surface 120 based on at least one of the vehicle speed information, the tail board control signal and the sensor group signal.

Wherein the cover driving mechanism comprises a cover stay 150.

As shown in fig. 12, the tail gate controller is also connected to the lifting stay 142 and the cover stay 150 for controlling the expansion and contraction of the lifting stay 142 and the cover stay 150.

In this step, under the condition that the truck is driven at a medium speed or at a high speed according to the vehicle speed information, if the signal of the first contact sensor 131 indicates that the tail lifting mechanism is not in contact with the first contact sensor 131, the tail lifting mechanism is driven to lift or descend until the received signal of the first contact sensor 131 indicates that the tail lifting mechanism is in contact with the first contact sensor 131.

The linkage of the tail board surface 120 and the vehicle speed information can be realized by neglecting the tail board control signal in medium-speed driving or high-speed driving of the truck, and the risk that personnel open the tail board surface 120 and the goods fall due to misoperation in the medium-speed driving or high-speed driving process of the truck is avoided.

According to the method for controlling the tail board of the carriage, provided by the embodiment of the application, the contact state between the tail board lifting mechanism and the tail board surface 120 can be sensed through the sensor groups arranged on the two opposite sides of the opening of the carriage body 110, so that the action of the tail board lifting mechanism or the cover driving mechanism is controlled, the fault tolerance and the stability are higher, can avoid the extrusion between the railway carriage or compartment body 110 and the tailboard face 120 to the damage of railway carriage or compartment body 110 and tailboard face 120, through the linkage between speed of a motor vehicle information and the tailboard face 120 control to lower cost has realized the control to tailboard face 120, can avoid the incident that does not have the lid to lead to because personnel's maloperation leads to the vehicle to travel in-process tailboard face 120, has promoted the security of vehicle in the in-process of traveling.

In some embodiments, controlling at least one of the tailgate lifting mechanism or the closing drive mechanism of the tailgate face 120 based on at least one of the vehicle speed information, the tailgate control signals, and the signals of the sensor group, comprises:

In the case that the vehicle speed information is determined to be greater than or equal to the vehicle speed threshold value and the signal output by the first contact sensor 131 is a non-contact signal, controlling the tail plate lifting mechanism to execute lifting action until the signal output by the first contact sensor 131 is a contact signal;

In the case where it is determined that the signal output from the second contact sensor 132 is a non-contact signal, the capping driving mechanism is controlled to perform the capping operation until the signal output from the second contact sensor 132 is a contact signal.

And under the condition that the vehicle speed information is greater than or equal to the vehicle speed threshold value, the truck is driven at a medium speed or a high speed.

As shown in fig. 13, when it is determined that the vehicle speed information is greater than or equal to the vehicle speed threshold value, the tailgate controller determines the signal output from the first contact sensor 131, and if the signal output from the first contact sensor 131 is a non-contact signal, the lifting arm 141 does not contact the first contact sensor 131, the tailgate controller drives the lifting lever 142 to expand and contract, and controls the tailgate panel 120 to lift until the lifting arm 141 contacts the first contact sensor 131, the signal output from the first contact sensor 131 is a contact signal, and the tailgate controller controls the lifting lever 142 to stop expanding and contracting.

If it is determined that the signal output by the first contact sensor 131 is a contact signal, the tailgate controller determines that the signal output by the second contact sensor 132, if the signal output by the second contact sensor 132 is a non-contact signal, the top of the tailgate panel 120 does not contact the second contact sensor 132, the tailgate controller drives the closing brace 150 to stretch and retract, controls the tailgate panel 120 to close the opening of the carriage 110 until the top of the tailgate panel 120 contacts the second contact sensor 132, and the signal output by the second contact sensor 132 is a contact signal, and the tailgate controller controls the closing brace 150 to stop stretching.

In this embodiment, through the linkage between the vehicle speed information and the control of the tail board panel 120, the tail board panel 120 is controlled to automatically cover the opening of the carriage 110, so that the safety accident caused by that the tail board panel 120 is not covered in the vehicle driving process due to misoperation of personnel is avoided, and the safety of the vehicle in the driving process is improved.

under the condition that the vehicle speed information is smaller than the vehicle speed threshold value, the signal output by the first contact sensor 131 is a non-contact signal, and the tail plate control signal is a lifting control signal, the tail plate lifting mechanism is controlled to execute lifting action until the signal output by the first contact sensor 131 is a contact signal.

The vehicle speed threshold value can be flexibly selected according to actual requirements, and the higher the vehicle speed threshold value is, the more flexible the vehicle speed threshold value is, and the lower the vehicle speed threshold value is, the safer the vehicle speed threshold value is, and the vehicle speed threshold value is, the more safe the vehicle speed threshold value is.

For example, if the vehicle speed threshold is set to 3km/h, the truck is in a low-speed driving or non-driving state if the vehicle speed information is less than 3 km/h.

Wherein, the lifting control signal is used for controlling the tail board lifting mechanism to execute lifting action on the tail board surface 120.

It will be appreciated that the non-contact signal output by the first contact sensor 131 is indicative of the lifting arm 141 not contacting the first contact sensor 131.

As shown in fig. 13, when it is determined that the vehicle speed information is smaller than the vehicle speed threshold value, the tailgate controller determines the signal output from the first contact sensor 131, and if the signal output from the first contact sensor 131 is a non-contact signal, the lift arm 141 does not contact the first contact sensor 131.

If the tail board controller receives a lifting control signal sent by the lifting switch, the tail board controller drives the lifting support rod 142 to stretch and retract, the tail board surface 120 is controlled to lift until the lifting arm 141 contacts the first contact sensor 131, the signal output by the first contact sensor 131 is a contact signal, the tail board controller controls the lifting support rod 142 to stop stretching or receives a signal which indicates that the lifting switch sends to stop driving, and the tail board controller controls the lifting support rod 142 to stop stretching.

In this embodiment, when the tail plate lifting mechanism contacts the first contact sensor 131, the driving is stopped, so that the effect of defy death is achieved, and the damage to the carriage body 110 and the tail plate surface 120 caused by the extrusion between the carriage body 110 and the tail plate surface 120 is avoided.

In the case where it is determined that the vehicle speed information is smaller than the vehicle speed threshold, the signal output by the second contact sensor 132 is a non-contact signal, and the tailgate control signal is a closing control signal, the closing driving mechanism is controlled to perform the closing operation until the signal output by the second contact sensor 132 is a contact signal.

The cover control signal is used for controlling the cover driving mechanism to perform the cover action on the tail board surface 120.

It will be appreciated that the non-contact signal output by the second contact sensor 132 is indicative of the top of the tailgate sheet 120 not contacting the second contact sensor 132.

As shown in fig. 13, when it is determined that the vehicle speed information is less than the vehicle speed threshold and the signal output from the first contact sensor 131 is a contact signal, or when it is determined that the vehicle speed information is less than the vehicle speed threshold and the expansion and contraction of the lift lever 142 is stopped, the tailgate controller determines that the signal output from the second contact sensor 132, and if the signal output from the second contact sensor 132 is a non-contact signal, the top of the tailgate panel 120 is not in contact with the second contact sensor 132.

If the tail board controller receives the closing control signal sent by the closing switch, the tail board controller drives the closing brace rod 150 to stretch and retract, controls the tail board surface 120 to close the opening of the carriage body 110 until the top of the tail board surface 120 contacts the second contact sensor 132, the signal output by the second contact sensor 132 is a contact signal, the tail board controller controls the closing brace rod 150 to stop stretching, or controls the closing brace rod 150 to stop stretching until receiving the signal representing that the closing switch sends to stop driving.

In this embodiment, when the cover driving mechanism contacts the second contact sensor 132, the driving is stopped, which has the effect of defy death, and the damage of the compression between the carriage 110 and the tailgate panel 120 to the carriage 110 and the tailgate panel 120 is avoided.

in the case that the vehicle speed information is determined to be smaller than the vehicle speed threshold value, the signal output by the first contact sensor 131 is a contact signal, the signal output by the second contact sensor 132 is a non-contact signal, and the tail plate control signal is a descending control signal, controlling the tail plate lifting mechanism to execute descending action;

Or controlling the closing driving mechanism to execute opening action under the condition that the vehicle speed information is determined to be smaller than the vehicle speed threshold value, signals output by the first contact sensor 131 and the second contact sensor 132 are contact signals and the tail plate control signal is an opening control signal;

or in the case that the vehicle speed information is determined to be smaller than the vehicle speed threshold value, the signals output by the first contact sensor 131 and the second contact sensor 132 are all contact signals, and the tail plate control signal is a descending control signal, the tail plate lifting mechanism is controlled to execute descending action.

The descending control signal is used for controlling the tail board lifting mechanism to execute descending action on the tail board surface 120, and the opening control signal is used for controlling the cover driving mechanism to execute opening action on the tail board surface 120.

It will be appreciated that the lift switch is also used to send a descent control signal to the tailgate controller and the cover switch is also used to send an opening control signal to the tailgate controller.

For example, when cargo is to be loaded into and unloaded from the vehicle compartment, the tailgate panel 120 needs to be opened and controlled to descend, and the tailgate panel 120 is lifted to the outer cargo platform edge, thereby facilitating the loading and unloading of the cargo by the carrier.

As shown in fig. 13, when it is determined that the vehicle speed information is less than the vehicle speed threshold and the signal output from the first contact sensor 131 is a contact signal, or when it is determined that the vehicle speed information is less than the vehicle speed threshold and the expansion and contraction of the lift lever 142 is stopped, the tailgate controller determines the signal output from the second contact sensor 132, and if the signal output from the second contact sensor 132 is a non-contact signal, the top of the tailgate panel 120 is not in contact with the second contact sensor 132, and the tailgate controller determines whether or not the closing control signal is received.

When the tail board controller does not receive the closing control signal sent by the closing switch and receives the descending control signal sent by the lifting switch, the tail board controller drives the lifting support rod 142 to stretch and retract, controls the tail board surface 120 to descend until receiving a signal indicating that driving is stopped and sent by the lifting switch, or controls the lifting support rod 142 to stretch and retract until the lifting support rod 142 stretches to a limited length.

In another embodiment, as shown in fig. 13, when it is determined that the vehicle speed information is less than the vehicle speed threshold and the signal output by the first contact sensor 131 is a contact signal, or when it is determined that the vehicle speed information is less than the vehicle speed threshold and the lifting lever 142 stops telescoping, the tailgate controller determines the signal output by the second contact sensor 132, and if the signal output by the second contact sensor 132 is a contact signal, the top of the tailgate panel 120 contacts the second contact sensor 132, and the tailgate controller determines whether the opening control signal is received.

Under the condition that the tail board controller receives an opening control signal sent by the closing switch, the tail board controller drives the closing stay bar 150 to stretch and retract, controls the tail board panel surface 120 to open the opening of the carriage body 110 until receiving a signal which is sent by the closing switch and is used for representing that driving is stopped, or until the closing stay bar 150 stretches to a limited length, and controls the closing stay bar 150 to stop stretching.

The tail board controller judges whether the descending control signal sent by the lifting switch is received, if the tail board controller receives the descending control signal sent by the lifting switch, the tail board controller drives the lifting support rod 142 to stretch and retract, the tail board surface 120 is controlled to descend until the signal representing stopping driving sent by the lifting switch is received, or until the lifting support rod 142 stretches to a limited length, the tail board controller controls the lifting support rod 142 to stop stretching.

Or under the condition that the tail board controller does not receive an opening control signal sent by the closing switch and receives a descending control signal sent by the lifting switch, the tail board controller drives the lifting support rod 142 to stretch and retract, the tail board surface 120 is controlled to descend until the tail board surface 120 receives a signal which indicates that the lifting switch sends the signal to stop driving, or until the lifting support rod 142 stretches to a limited length, the tail board controller controls the lifting support rod 142 to stop stretching.

After the lifting strut 142 stops telescoping, the tailgate controller may re-determine the received signal of the first contact sensor 131.

In this embodiment, the position of the tail board surface 120 is controlled by the descending control signal or the opening control signal, so that the tail board surface can be effectively adapted to various application scenarios, and the carrying operation is convenient.
