Description

Technical Field

[0001] The present invention relates to the technical field of logistics transportation, and in particular, to a cargo compartment buffer device, a control method for the cargo compartment buffer device, a vehicle, an electronic device, and a computer-readable storage medium. Background Art

[0002] During the transportation of van commercial vehicles, the cargo compartment often loads some scattered or difficult-to-fix goods. When the vehicle encounters sudden braking, sharp turning, or collision, the goods will generate relative displacement in the cargo compartment due to inertia, and are likely to collide with the side wall of the cargo compartment, resulting in damage to the goods. Especially for fragile or valuable items, such collisions may cause greater losses and increase the transportation cost.

[0003] The existing cargo protection solution is to set a fixed buffer structure (such as a buffer plate) to absorb the kinetic energy when the goods collide with the cargo compartment wall under the action of inertia, so as to reduce the collision risk. However, due to the non-adjustable position of this fixed buffer structure, it can only provide a limited buffer distance, and it is difficult to adjust according to the loading state in the cargo compartment and the changes in the specific vehicle state (such as sudden braking, sharp turning), which reduces its flexibility and actual buffer effect. At the same time, the fixed buffer structure may occupy more internal space of the cargo compartment, reducing the effective loading volume of the cargo compartment, thus affecting the transportation efficiency. Summary of the Invention

[0004] The present invention aims to at least solve one of the technical problems existing in the prior art. For this reason, one object of the present invention is to provide a cargo compartment buffer device, which realizes the position movement of the buffer plate, makes the distance between the buffer plate and the side wall of the cargo compartment controllable, can provide a greater buffer distance for the goods during impact, thus more effectively absorbing the kinetic energy of the goods colliding with the cargo compartment due to inertia, playing a role in protecting the goods, reducing the risk of damage to the goods. At the same time, the automatic reset of the buffer plate can ensure that the internal loading space of the cargo compartment is not affected.

[0010] According to the cargo compartment buffer device of the embodiment of the present invention, by arranging a plurality of buffer plates made of an elastic material parallel to the inner side wall of the cargo compartment and connecting a driving device, the buffer plates can dynamically adjust their positions based on the inertial action of the goods. When the goods impact the side wall of the cargo compartment due to inertial action, at least one buffer plate can move from the initial position towards the inside of the cargo compartment under the action of the driving device, that is, move in the opposite direction of the side wall of the cargo compartment, thereby increasing the distance between the buffer plate and the side wall of the cargo compartment, enabling the goods to have a greater buffer distance under inertial action, thus more effectively absorbing the impact energy brought by the impact of the goods, playing a role in shock absorption and protecting the goods, and reducing the risk of damage to the goods. At the same time, after completing the buffering task, the buffer plate can automatically reset to the initial position with the help of the driving device, avoiding long-term excessive occupation of the effective loading space inside the cargo compartment and ensuring that the loading volume of the cargo compartment is not affected.

[0015] To achieve the above object, a control method of a cargo compartment buffer device according to a second aspect embodiment of the present invention is used to control the cargo compartment buffer device as described in the above embodiments. The control method includes: determining that the vehicle meets the condition that the cargo in the cargo compartment generates kinetic energy; and controlling the buffer plate at the corresponding side wall position in the cargo compartment to move from the initial position into the cargo compartment according to the condition that the vehicle meets the condition that the cargo in the cargo compartment generates kinetic energy.

[0016] According to the control method of the cargo compartment buffer device of the embodiment of the present invention, by judging whether the vehicle meets the condition that the cargo in the cargo compartment generates kinetic energy, the risk of displacement of the cargo in the cargo compartment due to inertia can be evaluated in real time, and the moving direction of the buffer plate can be controlled according to this judgment. When it is determined that the vehicle meets the condition that the cargo in the cargo compartment generates kinetic energy, the buffer plate at the corresponding side wall position in the cargo compartment is controlled to move from the initial position into the cargo compartment, that is, move in the opposite direction of the cargo compartment side wall. In this way, before the cargo undergoes inertial displacement, the position of the buffer plate can be actively adjusted to increase the distance between the buffer plate and the cargo compartment side wall, so that the cargo has a greater buffer distance under the action of inertia, thereby more effectively absorbing the impact energy brought by the impact of the cargo, playing a role in shock absorption and protecting the cargo, and reducing the risk of damage to the cargo.

[0017] In some embodiments, determining that the vehicle meets the condition for the goods in the cargo compartment to generate kinetic energy includes: when it is determined according to the acceleration information of the vehicle that the vehicle generates an acceleration and the value of the acceleration exceeds the acceleration threshold in the acceleration direction, the vehicle meets the condition for the goods in the cargo compartment to generate kinetic energy; or, when it is determined according to the pose information of the vehicle that the vehicle generates a deflection and the deflection angle exceeds the deflection angle threshold, the vehicle meets the condition for the goods in the cargo compartment to generate kinetic energy; or, when it is determined according to the pose information of the vehicle that the vehicle generates a roll angle and the value of the roll angle exceeds the roll angle threshold, the vehicle meets the condition for the goods in the cargo compartment to generate kinetic energy; or, when an operation instruction for the vehicle to suddenly brake or change lanes is received from the advanced driver assistance system of the vehicle, the vehicle meets the condition for the goods in the cargo compartment to generate kinetic energy.

[0019] In some embodiments, the control method further includes: when the vehicle no longer meets the condition for the goods in the cargo compartment to generate kinetic energy, controlling the buffer plate at the corresponding position in the cargo compartment to move out of the cargo compartment to return to the initial position.

[0020] In some embodiments, the control method further includes: obtaining the distance information between the target goods generating kinetic energy and the target buffer plate; determining the target moving distance of the piston in the target piston structure corresponding to the target buffer plate according to the distance information; controlling the rotational speed of the pump body in the energy storage device according to the target moving distance to control the flow rate of the driving substance at the material outlet of the energy storage device.

[0021] To achieve the above object, a vehicle according to an embodiment of the third aspect of the present invention includes: a cargo compartment; a detection device for detecting vehicle operation state information; the cargo compartment buffer device described in the above embodiments; the controller of the cargo compartment buffer device is connected to the detection device, and the controller is further configured to execute the control method of the cargo compartment buffer device described in the above embodiments.

[0022] For a vehicle according to an embodiment of the present invention, the controller of the cargo compartment buffer device is connected to the detection device. The detection device can detect the vehicle operation state information in real time and transmit this information to the controller in the cargo compartment buffer device, enabling the controller to, according to the dynamic operation of the vehicle, adopt the control method of the cargo compartment buffer device described in the above embodiment. When the vehicle meets the condition that the goods in the cargo compartment generate kinetic energy, the controller controls the buffer plate at the corresponding side wall position in the cargo compartment to move from the initial position into the cargo compartment, that is, to move in the opposite direction of the cargo compartment side wall. In this way, before the goods undergo inertial displacement, the active adjustment of the buffer plate position can be achieved, increasing the distance between the buffer plate and the cargo compartment side wall, enabling the goods to have a greater buffer distance under the action of inertia, and further more effectively absorbing the impact energy generated by the impact of the goods due to inertia, thereby playing a role in shock absorption and protecting the goods, reducing the risk of damage to the goods, and improving the transportation efficiency of the vehicle and the safety of the goods.

[0023] To achieve the above object, an electronic device according to an embodiment of the fourth aspect of the present invention includes: at least one processor; a memory communicatively connected to the at least one processor; a computer program stored in the memory that can be executed by the at least one processor, and when the at least one processor executes the computer program, the control method of the cargo compartment buffer device described in the above embodiment is implemented.

In this way, before the goods undergo inertial displacement, the active adjustment of the buffer plate position can be achieved, increasing the distance between the buffer plate and the cargo compartment side wall, enabling the goods to have a greater buffer distance under the action of inertia, and further more effectively absorbing the impact energy generated by the impact of the goods due to inertia, thereby playing a role in shock absorption and protecting the goods, reducing the risk of damage to the goods, and improving the transportation efficiency of the vehicle and the safety of the goods.

Detailed implementation manners

[0030] Embodiments of the present invention will be described in detail below. The embodiments described with reference to the accompanying drawings are exemplary. Embodiments of the present invention will be described in detail below.

[0031] Reference will be made below to Figures 1 - 4 describe a cargo compartment buffer device according to an embodiment of the present invention.

[0032] Figure 1 is a block diagram of a cargo compartment buffer device according to an embodiment of the present invention. As Figure 1 shown, the cargo compartment buffer device 1 includes: a plurality of buffer plates 11 and a driving device 12.

[0033] In some embodiments, the buffer plate 11 can be a component for absorbing and alleviating the impact force generated by the goods during transportation. Its main function is to absorb the impact energy through its elastic deformation, thereby avoiding the direct impact of the goods on the side wall of the cargo compartment and protecting the goods from damage. This is because during transportation, especially when the vehicle makes a sharp turn, accelerates suddenly or collides, the goods are prone to impact the side wall of the cargo compartment due to inertia. The setting of the buffer plate 11 helps prevent the goods from directly impacting the hard structure of the cargo compartment 2, playing a buffering and protective role.

[0034] In some embodiments, the buffer plate 11 can be made of an elastic material, having a certain stiffness while being elastic, and can absorb the kinetic energy of the impact between the goods and the cargo compartment 2, thereby reducing the damage to the goods. Common elastic materials include but are not limited to TPO (Thermoplastic Polyolefin) materials, rubber materials, PU (Polyurethane) materials, EVA (Ethylene Vinyl Acetate) foam materials or other materials.

[0035] Among them, the TPO material is an ideal elastic material, which has durability, impact resistance and good energy absorption characteristics. TPO can be injection molded to produce a buffer plate 11 with complex shapes and high durability, which can maintain stable elasticity and shape under repeated stress, and can still maintain stable physical properties at various temperatures in the transportation environment. The PU material has high strength and large deformation recovery ability, can maintain good elasticity under repeated impacts, and is not easy to age. The toughness of PU is good, suitable for use in low-temperature environments, especially suitable for applications in the north or alpine regions. The EVA material is a material with a low density but high buffering performance, which can be made by a foaming process. This material is light, has good elasticity, and low cost, and is suitable for applications where the goods are light and small, providing flexible buffering for the goods.

[0036] In some embodiments, such as Figure 2 and Figure 3 shown, a plurality of buffer plates 11 are adapted to be disposed in the cargo compartment 2 and surround along the side wall of the cargo compartment 2, and each buffer plate 11 is adapted to be disposed parallel to the corresponding side wall of the cargo compartment 2. Among them, surrounding the side wall of the cargo compartment 2 by a plurality of buffer plates 11 can ensure the formation of an effective buffer area in all directions of the cargo compartment 2. This design can provide all-round protection and significantly improve the safety of the goods during loading and transportation. The parallel arrangement structure helps the buffer plate 11 to maintain a consistent gap with the side wall, so that the impact force can be more comprehensively distributed when the goods impact. In this way, the buffer plate 11 can withstand a uniform lateral impact force when the goods impact, facilitating the provision of consistent support on the entire impact surface and avoiding excessive impact damage or deformation caused by concentrated stress on a certain area.

[0037] In some embodiments, the driving device 12 can be a device that generates mechanical force and controls the movement of the buffer plate 11. The driving device 12 is connected to a plurality of buffer plates 11 and is used to drive at least one of the plurality of buffer plates 11 to move from an initial position towards the inside of the cargo compartment 2 or towards the outside of the cargo compartment 2 to return to the initial position. Among them, the initial position is the static position of the buffer plate 11 when it is not affected by any external force, and it can be at a position where the buffer plate 11 is closer to the side wall of the cargo compartment. This position can still provide a certain degree of protection for the goods and does not affect the loading space inside the cargo compartment 2.

[0038] In some embodiments, the driving device 12 is used to drive at least one of the plurality of buffer plates 11 to move from the initial position towards the inside of the cargo compartment 2, that is, the buffer plate 11 moves in a direction away from the side wall of the cargo compartment. The purpose of this is to increase the buffer distance between the buffer plate 11 and the side wall of the cargo compartment by adjusting the position of the buffer plate 11 in advance before the goods have inertial displacement, so as to provide a larger buffer space. This will help to reduce the impact energy caused by inertial movement when the goods impact the buffer plate 11 due to inertial movement, thus ensuring the safety of the goods.

[0039] In some embodiments, the driving device 12 is configured to drive at least one of the plurality of buffer plates 11 to move outwardly toward the outside of the cargo compartment 2 to return to the initial position. The purpose of this is that after the buffer plate 11 has completed its buffering function, it can be driven back by the driving device 12 to its original position closer to the side wall of the cargo compartment, which ensures that the loading space inside the cargo compartment 2 is not affected, thereby maintaining the maximum capacity of the cargo compartment 2 when buffering is not required. In addition, this reset mechanism enables the buffer plate 11 to quickly return to the ready state after each buffering, so as to be prepared for the next buffering action.

[0040] For the cargo compartment buffering device 1 according to an embodiment of the present invention, by arranging a plurality of buffer plates 11 made of an elastic material in parallel on the side wall of the cargo compartment 2 and connecting the driving device 12, the buffer plates 11 can dynamically adjust their positions based on the inertia of the goods. When the goods impact the side wall of the cargo compartment 2 due to inertia, at least one buffer plate 11 can move inwardly toward the inside of the cargo compartment 2 under the action of the driving device 12, that is, move in the opposite direction of the side wall of the cargo compartment, thereby increasing the distance between the buffer plate 11 and the side wall of the cargo compartment, enabling the goods to have a greater buffering distance under the action of inertia, thus more effectively absorbing the impact energy brought by the impact of the goods, playing a role in shock absorption and protecting the goods, and reducing the risk of damage to the goods. At the same time, after the buffer plate 11 has completed its buffering task, it can automatically reset to the initial position with the help of the driving device 12, avoiding long-term excessive occupation of the effective loading space inside the cargo compartment 2 and ensuring that the loading volume of the cargo compartment 2 is not affected.

[0041] Figure 4 is a schematic diagram of a driving device according to an embodiment of the present invention, as Figure 4 shown, the driving device 12 includes: an energy storage device 121 and a plurality of piston structures 122.

[0042] In some embodiments, the energy storage device 121 can be a component for storing energy and releasing energy when needed, and its main function is to provide driving force for the buffer plate 11. This device can take various forms, such as pneumatic energy storage or hydraulic energy storage. Among them, pneumatic energy storage generates driving force through high-pressure gas, while hydraulic energy storage relies on liquid pressure to push the piston structure 122. The energy storage device 121 is suitable for being arranged on the vehicle, and can be located in the cab, inside the cargo compartment 2 or other appropriate positions. The specific position can be set according to the vehicle structure and loading requirements.

[0043] In some embodiments, a driving substance is stored in the energy storage device 121. Herein, the driving substance may refer to the medium stored in the energy storage device 121 for driving the piston 1222 to move. The driving substance may be a high-pressure gas (such as air or nitrogen, etc.) or a liquid (such as water, hydraulic oil or aqueous ethylene glycol solution, etc.). High-pressure gases are suitable for scenarios with relatively fast response speeds, while liquids are suitable for applications requiring high stability and large driving forces. When the goods undergo inertial displacement during transportation, the energy storage device 121 can quickly release the driving substance to push the buffer plate 11, providing buffer protection for the goods, thereby reducing the impact force between the goods and the side wall of the cargo compartment.

[0044] In some embodiments, the plurality of piston structures 122 are important components of the driving device 12, and their main function is to convert the energy of the driving substance released by the energy storage device 121 into mechanical motion. Each piston structure 122 is connected to the energy storage device 121, and each buffer plate 11 is connected to at least one piston structure, and is used to drive the buffer plate 11 to move through the driving of the driving substance. Under the buffer task, the buffer plate 11 moves towards the inside of the cargo compartment 2, increasing the buffer distance between the goods and the side wall of the cargo compartment, thereby more effectively absorbing the impact energy. After the buffer task is completed, the piston structure 122 can restore the buffer plate 11 to its initial position to ensure that the internal loading space of the cargo compartment 2 is not affected.

[0045] In some embodiments, at least one piston structure 122 may be one piston structure 122, two piston structures 122, four piston structures 122, eight piston structures 122 or a greater number of piston structures 122. The specific number of piston structures 122 can be set according to factors such as the weight of the goods, the volume of the buffer plate, the required buffer performance, and the equipment cost, so as to ensure that the driving device 12 can provide sufficient driving force to meet the support and driving requirements of the buffer plate 11.

[0046] For example, as Figure 3 shown, each buffer plate 11 can be connected to four piston structures 122, and the four piston structures 122 are respectively connected to the parts at the four corners of the corresponding buffer plate 11 to drive the buffer plate 11 to move. Among them, the four piston structures 122 can act on the buffer plate 11 in a coordinated manner, thereby providing a uniform driving force, enabling the buffer plate 11 to move smoothly and precisely, and avoiding tilting or uneven pushing of the buffer plate 11 during the movement process.

[0047] Specifically, the four piston structures 122 work in coordination through a control system, and the generated driving force is transmitted through the four corners respectively connected to the buffer plate 11. This design method can ensure that the buffer plate 11 moves in an accurate manner, and the movements of the respective pistons 1222 can cooperate with each other, which helps to better control the moving direction and angle of the buffer plate 11 to achieve effective position adjustment of the buffer plate 11 within the cargo compartment 2. In this way, the buffer plate 11 can provide the maximum buffer distance when the goods impact, thereby absorbing more impact energy. At the same time, through four-point support, the force distribution on the buffer plate 11 is more uniform, which can effectively reduce the damage caused by local pressure concentration, thereby improving the safety and stability during cargo transportation.

[0048] As Figure 4 shown, each piston structure 122 includes: a cylinder block 1221, a piston 1222, and a piston rod 1223. Among them, the cylinder block 1221 (i.e., the enclosed cavity where the piston 1222 is located) is the main fixed component of the piston structure 122, and its function is to provide a sealed space for the movement of the piston 1222. The length of the cylinder block 1221 can be designed according to the movement requirements of the piston 1222 to ensure that the piston 1222 can freely move to the required distance inside it. The cylinder block material can be high-strength metal (such as steel or aluminum alloy) or engineering plastic to ensure its sufficient strength and durability to maintain stability during long-term use.

[0049] In some embodiments, the cylinder block 1221 can be firmly installed on the cargo compartment 2 by welding, bolt fixing, or other mechanical fixing methods, and the specific position can be designed according to the internal structure of the cargo compartment 2 and the required buffering effect.

[0050] In some embodiments, the piston 1222 is located inside the cylinder block 1221 and is movable along the length direction of the cylinder block 1221. The piston 1222 performs a linear reciprocating motion inside the cylinder block 1221 under the action of the driving substance, converting the pressure released from the energy storage device 121 into a driving force. Therefore, the main function of the piston 1222 is to transmit the driving force to the piston rod 1223 to move the buffer plate 11 and provide a buffering effect.

[0051] In some embodiments, a sealing ring or sealing structure can be provided on the surface of the piston 1222 to ensure the sealing of the driving substance inside the cylinder block 1221 and prevent leakage. This sealing structure can adopt an O-ring or other forms of sealing materials to reduce the friction between the cylinder block 1221 and the piston 1222, and at the same time ensure that the piston 1222 can move smoothly, thereby improving the stability and service life of the buffering device.

[0052] In some embodiments, the piston rod 1223 is a transmission component connecting the piston 1222 and the buffer plate 11. One end of the piston rod 1223 penetrates through the top of the cylinder block 1221 and can be connected to the corresponding buffer plate 11 by means of threading or welding. The other end of the piston rod 1223 can also be connected to the piston 1222 by threading or welding. The extension or retraction of the piston rod 1223 can move the buffer plate 11 within the cargo compartment 2.

[0053] In some embodiments, the piston rod 1223 can be made of wear-resistant high-strength metal (such as chrome-plated steel or aluminum alloy), which can withstand the stress during the reciprocating motion of the piston 1222 and avoid bending or breaking. The length and diameter of the piston rod 1223 can be designed according to the weight of the buffer plate 11 and the distance of movement within the cargo compartment 2. A guide sleeve or sealing structure can be designed at the material outlet of the piston rod 1223 and the cylinder block 1221 to ensure the stability of the movement of the piston rod 1223 and prevent swaying or deviation during the movement process.

[0054] In some embodiments, a first interface 1224 and a second interface 1225 are constructed on the cylinder block 1221. The second interface 1225 and the first interface 1224 are arranged at intervals along the length direction of the cylinder block 1221. The first interface 1224 is close to the bottom of the cylinder block 1221, and the second interface 1225 is close to the top of the cylinder block 1221. Among them, arranging the first interface 1224 and the second interface 1225 at intervals can effectively avoid interference during the charging and discharging processes of the driving substance. The specific distance of the interval arrangement can be set according to factors such as the total length of the cylinder block 1221 and the piston stroke.

[0055] In some embodiments, the first interface 1224 and the second interface 1225 are respectively connected to the energy storage device 121, for transporting the driving substance in the energy storage device 121 to the cylinder block 1221, or transporting the driving substance in the cylinder block 1221 back to the energy storage device 121. The size and structure of the first interface 1224 and the second interface 1225 can be designed according to the type of the driving substance, the size of the cylinder block 1221, and the required pressure to ensure safety and operation efficiency when charging and discharging the driving substance.

[0056] In some embodiments, the first interface 1224 and the second interface 1225 can be designed as exhaust interfaces or drain interfaces to adapt to different types of driving substances (gases or liquids).

[0057] In some embodiments, when the vehicle meets the condition that the goods in the cargo compartment 2 generate kinetic energy, the first interface 1224 and the second interface 1225 are connected. The driving substance in the energy storage device 121 is filled into the cylinder body 1221 through the first interface 1224, and the driving substance in the upper part of the cylinder body 1221 flows back to the energy storage device 121 through the second interface 1225 to drive the piston to move upward, so that the corresponding buffer plate 11 moves from the initial position towards the inside of the cargo compartment 2; or, when the vehicle does not meet the condition that the goods in the cargo compartment 2 generate kinetic energy, the first interface 1224 and the second interface 1225 are connected. The driving substance in the energy storage device 121 is filled into the cylinder body 1221 through the second interface 1225, and the driving substance at the bottom of the piston is released to the energy storage device 121 through the first interface 1224 to drive the piston to move towards the bottom of the cylinder body 1221, so that the corresponding buffer plate 11 moves towards the outside of the cargo compartment 2 to return to the initial position.

[0058] In some embodiments, as Figure 4 shown, the energy storage device 121 includes: an energy storage tank 1211, a pump body, and a control valve 1212. Among them, the energy storage tank 1211 is a container for storing the driving substance, and its design can vary according to the driving substance (gas or liquid) stored. For example: The pneumatic energy storage tank has a high-strength material structure and is suitable for storing high-pressure gases such as air or nitrogen. The pneumatic energy storage tank can be provided with a safety valve to prevent explosion or leakage when the internal pressure is too high. The hydraulic energy storage tank can have a corrosion-resistant coating and a sealing device and is suitable for storing liquid driving substances such as hydraulic oil or ethylene glycol aqueous solution to prevent liquid leakage or contamination. In addition, the design of the energy storage tank 1211 can consider the volume, pressure-bearing capacity, and adaptability of the connection interface with the control valve 1212 to ensure stable and smooth flow during the charging and discharging process of the driving substance.

[0059] In some embodiments, the energy storage tank 1211 is configured with a substance outlet, and the specific position and design of the substance outlet can be adjusted according to the installation method and spatial layout of the energy storage tank 1211 to ensure that the driving substance can flow quickly and smoothly towards the control valve 1212.

[0060] In some embodiments, the energy storage tank 1211 is configured with a substance return port, and the specific position and design of the substance return port can be adjusted according to the installation method and spatial layout of the energy storage tank 1211 to ensure that the driving substance can flow quickly and smoothly back to the energy storage tank 1211.

[0061] In some embodiments, the pump body is used to pump the driving substance in the energy storage tank 1211 to the substance outlet. The pump body can be a hydraulic pump, an air pump, an electric pump, etc.

[0062] In some embodiments, the control valve 1212 may be a device for regulating the flow direction and flow rate of the driving substance (such as gas or liquid) in the energy storage tank 1211. The first end of the control valve 1212 is connected to the substance outlet and the substance return port of the energy storage tank 1211. The second end of the control valve 1212 is connected to the first interface 1224 and the second interface 1225 of each piston structure 122 through a connecting pipeline. The control valve 1212 is used to control the connection state between the first interface 1224 and the substance return port and the substance outlet, and to control the connection state between the second interface 1225 and the substance return port and the substance outlet, so as to switch the flow direction of the driving substance in the first interface 1224 and the second interface 1225.

[0063] In some embodiments, the control valve 1212 includes a plurality of pipeline interfaces 1213. The plurality of pipeline interfaces 1213 are connected to the first interface 1224 and the second interface 1225 of each piston structure 122 through a connecting pipeline. The pipeline interfaces 1213 can adopt quick-connect interfaces, threaded interfaces or welded interfaces, which depends on the flow rate, pressure and durability requirements of the energy storage tank 1211. In gas drive, the sealing performance of the interface is very important. Therefore, metal sealing rings or O-rings can be used to ensure no leakage. The materials of the pipeline interfaces 1213 and the connecting pipeline can have high corrosion resistance and compressive capacity, such as stainless steel, copper alloy or high-strength plastic, to ensure long-term use.

[0064] In some embodiments, the control valve 1212 can be a mechanical control valve or an electronic control valve.

[0065] In some embodiments, as Figure 4 shown, the cargo compartment buffer device 1 includes a plurality of buffer plates 11. The plurality of buffer plates 11 are arranged parallel to the corresponding inner side walls of the cargo compartment 2. The plurality of inner side walls of the cargo compartment 2 at least include a left side wall, a right side wall, a front wall and a rear wall, so as to ensure the formation of an effective buffer area in all directions of the cargo compartment 2. This design can provide all-round protection and significantly improve the safety of the goods during loading and transportation.

[0066] In some embodiments, the driving device 12 includes a plurality of piston structures 122. Each buffer plate 11 is connected to at least one piston structure 122. Among them, at least one piston structure 122 can be one, two, four or other numbers of piston structures 122. The specific number can be selected according to factors such as the weight and volume of the goods, the weight and volume of the buffer plate 11, the buffer effect requirements, the design structure of the driving device 12, and the equipment cost.

[0067] In some embodiments, as Figure 4As shown, each buffer plate 11 is connected to four piston structures 122, and the four piston structures 122 are respectively connected to the parts at the four corners of the corresponding buffer plate 11 to drive the buffer plate 11 to move. Among them, the four piston structures 122 can act on the buffer plate 11 in a coordinated manner, so as to provide a uniform driving force, enabling the buffer plate 11 to move smoothly and precisely, and avoiding tilting or uneven pushing of the buffer plate 11 during the movement process.

[0068] Specifically, the four piston structures 122 work in coordination through a control system, and the generated driving force is transmitted through their respective connections to the four corners of the buffer plate 11. This design method can ensure that the buffer plate 11 moves in an accurate manner, and the movements of the respective pistons 1222 can cooperate with each other, which helps to better control the moving direction and angle of the buffer plate 11 to achieve effective position adjustment of the buffer plate 11 in the cargo compartment 2. In this way, the buffer plate 11 can provide the maximum buffer distance during the impact of the goods, thereby absorbing more impact energy. At the same time, through four-point support, the force distribution of the buffer plate 11 is more uniform, which can effectively reduce the damage caused by local pressure concentration, thereby improving the safety and stability during cargo transportation.

[0069] In some embodiments, there is a first preset distance between the initial position of the buffer plate 11 and the corresponding side wall of the cargo compartment 2. Among them, the design of having a first preset distance is to maintain a reasonable interval between the buffer plate 11 and the corresponding side wall of the cargo compartment 2 when the cargo compartment buffer device 1 is in a non-working state. Specifically, in the non-working state, the first preset distance provides a small-sized buffer space, which can provide a certain degree of protection for the goods and reduce the damage to the goods caused by vibrations during transportation. For example, when the goods have small vibrations or displacements, the buffer plate 11 can absorb a certain amount of energy to prevent the goods from directly contacting the side wall, and this protective effect is particularly important in the transportation of fragile items. However, if the first preset distance is designed too large, it may cause the buffer device to occupy part of the space in the cargo compartment 2, reducing the effective loading space and limiting the volume of the cargo compartment 2.

[0070] Therefore, the first preset distance should be controlled within a reasonable range. This distance should not be too large, otherwise it will affect the effective loading space in the cargo compartment 2 and reduce the space utilization rate; nor should it be too small to ensure that the cargo compartment buffer device 1 can provide a certain degree of protection for the goods in the non-working state.

[0071] In some embodiments, the cargo compartment buffer device 1 further includes: a distance detection module configured to detect distance information between a target cargo generating kinetic energy and a target buffer plate. The distance detection module may include, but is not limited to, an infrared sensor, an ultrasonic sensor, etc. The installation position of the distance detection module may be set according to the position where items are placed in the cargo compartment or the shape of the items, etc., for example, at a position on the inner wall of the cargo compartment where the distance between the target buffer plate and the corresponding item can be detected.

[0072] In some embodiments, multiple distance detection modules may be arranged at intervals. The multiple distance detection modules can detect different distances, and the distance between the current buffer plate and the cargo is determined by determining which distance detection module can detect a distance value. For example, two distance detection modules are set to detect the distance between a buffer plate and an item. The first distance detection module can detect 8 cm, and the second distance detection module can detect 10 cm. When the second distance detection module can detect a distance value while the first distance detection module cannot, it is determined that the distance between the buffer plate and the item is 10 cm.

[0073] In some embodiments, the controller is connected to the distance detection module, the pump body, and the control valve 1212. The controller is configured to control the control valve 1212, and is further configured to determine a target moving distance of the piston according to the distance information, and control the rotational speed of the pump body according to the target moving distance to control the flow rate of the driving substance at the substance outlet.

[0074] In some embodiments, the controller may be a separate dedicated controller, or a vehicle-integrated controller or domain controller, or other electronic devices that can be configured with this function.

[0075] Next, refer to Figure 5 Describe a control method for a cargo compartment buffer device according to an embodiment of the present invention.

[0076] Figure 5 is a flowchart of a control method for a cargo compartment buffer device according to an embodiment of the present invention. As Figure 5 shown, the control method for the cargo compartment buffer device according to the embodiment of the present invention includes at least steps S1 - S2, specifically as follows: S1, determine that the vehicle meets the condition for the cargo in the cargo compartment to generate kinetic energy.

[0077] In some embodiments, during the transportation of goods, the goods in the cargo compartment are usually in a relatively stationary state. When the vehicle is driving smoothly, the displacement and impact of the goods are less, and the influence of external forces is relatively low. However, in certain specific driving operations or external events, the goods in the cargo compartment may generate kinetic energy due to inertia and external forces. This kinetic energy can cause the goods to displace or even impact the side wall of the cargo compartment, thereby potentially damaging the goods themselves or the cargo compartment. Therefore, determining the conditions under which the vehicle satisfies the generation of kinetic energy of the goods in the cargo compartment is a preventive measure for protecting the goods. By identifying and responding to the conditions for generating kinetic energy in advance, the control system can enter the buffering state before the danger occurs, providing sufficient time for the system to adjust the position of the buffer plate. Thus, the risk of damage to the goods can be reduced. This preventive buffering measure is particularly applicable to scenarios where fragile or valuable items are transported to improve the transportation safety of the goods.

[0078] In some embodiments, the kinetic energy of the goods in the cargo compartment can be generated under multiple scenarios or driving operations, which can be used as a reference basis for determining conditions, including but not limited to: rapid acceleration, rapid deceleration, sharp turning, collision, rollover, uphill and downhill, and very bumpy sections. These scenarios will cause significant speed changes and direction changes of the goods, thereby generating relatively high kinetic energy.

[0079] S2. According to the conditions under which the vehicle satisfies the generation of kinetic energy of the goods in the cargo compartment, control the buffer plate at the corresponding side wall position in the cargo compartment to move from the initial position into the cargo compartment.

[0080] Specifically, when the cargo compartment buffering device is in a non-operating state, the control valve is in a closed state, the buffer plate remains in the initial position, and the system is in a standby state. When it is determined that the vehicle satisfies the conditions for generating kinetic energy of the goods in the cargo compartment, the control system can send a control signal to the driving device to start the driving device. The energy storage tank in the driving device pre-stores driving substances such as high-pressure gas or liquid as the energy source for providing driving force.

[0081] Furthermore, by adjusting the control valve, the substance outlet of the energy storage tank is connected to the first interface, and the substance return port of the energy storage tank is connected to the second interface. The driving substance can flow from the substance outlet of the energy storage tank, through the corresponding pipeline interface and connecting pipeline, to the first interface, and then enter the cylinder body of the piston structure. And the driving substance in the upper part of the cylinder body flows back to the energy storage device through the second interface and the substance return port. The whole process will generate pressure on the piston to drive the piston to move upward along the length direction of the cylinder body, so that the piston rod extends, thereby pushing the corresponding buffer plate to move from the initial position towards the inside of the cargo compartment. During the process of the buffer plate moving into the cargo compartment, it gradually approaches the position of the goods, increasing the distance between the buffer plate and the side wall of the cargo compartment, providing a larger buffering space for the goods, and thus more effectively absorbing the impact energy brought by the impact of the goods, playing a role in protecting the goods.

[0082] Further, after buffering is completed, when the vehicle returns to a stable state again, the controller can adjust the control valve so that the driving substance in the energy storage device is filled into the cylinder through the second interface, and the driving substance at the bottom of the piston is released to the energy storage device through the first interface, to drive the piston to move towards the bottom of the cylinder, so that the corresponding buffer plate moves towards the outside of the cargo compartment to return to the initial position, preparing for the next buffering.

[0083] According to the control method of the cargo compartment buffering device of the embodiment of the present invention, by judging whether the vehicle meets the condition that the goods in the cargo compartment generate kinetic energy, the risk of displacement of the goods in the cargo compartment due to inertia can be evaluated in real time, and the moving direction of the buffer plate can be controlled based on this judgment. When it is determined that the vehicle meets the condition that the goods in the cargo compartment generate kinetic energy, the buffer plate at the corresponding side wall position in the cargo compartment is controlled to move from the initial position towards the inside of the cargo compartment, that is, move in the opposite direction to the side wall of the cargo compartment. In this way, before the goods undergo inertial displacement, the position of the buffer plate can be actively adjusted to increase the distance between the buffer plate and the side wall of the cargo compartment, so that the goods have a greater buffering distance under the action of inertia, thereby more effectively absorbing the impact energy brought by the impact of the goods, playing a role in shock absorption and protecting the goods, and reducing the risk of damage to the goods.

[0084] In some embodiments, determining that the vehicle meets the condition that the goods in the cargo compartment generate kinetic energy includes: when it is determined according to the acceleration information of the vehicle that the vehicle generates an acceleration and the value of the acceleration exceeds the acceleration threshold in the acceleration direction, the vehicle meets the condition that the goods in the cargo compartment generate kinetic energy; or, when it is determined according to the pose information of the vehicle that the vehicle generates a deflection and the deflection angle exceeds the deflection angle threshold, the vehicle meets the condition that the goods in the cargo compartment generate kinetic energy; or, when it is determined according to the pose information of the vehicle that the vehicle generates a roll angle and the value of the roll angle exceeds the roll angle threshold, the vehicle meets the condition that the goods in the cargo compartment generate kinetic energy; or, when receiving an operation instruction of sudden braking or lane change sent by the vehicle's Advanced Driver Assistance System (ADAS), the vehicle meets the condition that the goods in the cargo compartment generate kinetic energy.

[0085] Among them, the acceleration information reflects the acceleration of the vehicle in each direction and is used to evaluate whether the vehicle's driving generates dynamic behaviors such as sudden acceleration and sudden deceleration that may cause the goods to displace. The acceleration information can be obtained from an acceleration sensor in the vehicle. The pose information reflects the pose of the vehicle in three-dimensional space, mainly including the vehicle's deflection angle (such as steering) and roll angle (such as the vehicle body tilting laterally), and is used to judge whether the vehicle is in a posture that is likely to cause the goods to be unstable. The pose information can be obtained from a yaw angle sensor and a roll sensor in the vehicle.

[0086] ADAS obtains road conditions and vehicle surrounding environment data through sensors such as lidar, millimeter-wave radar, and cameras. These data can not only help the control system judge the driving behavior of the vehicle, but also predict possible vehicle dynamic changes based on factors such as road conditions and front obstacles, thereby providing a basis for the activation of the cargo compartment buffer device. ADAS can be used to monitor the active dynamic behavior of the vehicle, such as driving behavior in situations like emergency braking and lane changing. And it combines road conditions to determine whether there are situations that may cause kinetic energy in the cargo. These information provide a basis for the activation of the cargo compartment buffer device, ensuring that during vehicle driving, the buffer device can be activated in a timely manner as needed, thus providing a greater buffer distance for the cargo.

[0087] Specifically, as Figure 6 shown, the acceleration sensor is used to detect the acceleration information of the vehicle in real time, the yaw angle sensor is used to detect the deflection angle of the vehicle body in real time. The roll sensor is used to detect the roll angle of the vehicle in real time, and the advanced driver assistance system is used to detect the distance and relative speed between the vehicle and surrounding objects in real time. Through a calibration algorithm, the possibility of operations such as emergency braking or lane changing (sharp turn) of the vehicle can be calculated, and these data signals are transmitted to the controller The controller analyzes these data according to a pre-set control logic. That is, when the vehicle makes driving behaviors such as sudden acceleration, sudden deceleration, and sharp turn, or when the vehicle collides or rolls over, the vehicle acceleration and body posture change. When the value of the acceleration exceeds the acceleration threshold in the acceleration direction, or the deflection angle exceeds the deflection angle threshold, or the value of the roll angle exceeds the roll angle threshold, or when receiving the operation instructions of sudden braking or lane changing sent by the vehicle's advanced driver assistance system, it is determined that the vehicle meets the conditions for the cargo in the cargo compartment to generate kinetic energy.

[0088] Furthermore, the controller sends a signal to the energy storage tank through a pre-calibrated control logic. The energy storage tank pre-stores driving substances such as high-pressure gas or liquid. By adjusting the control valve, the substance outlet of the energy storage tank is connected to the first interface, and the substance return port of the energy storage tank is connected to the second interface. The driving substance can flow from the substance outlet of the energy storage tank, through the corresponding pipeline interface and connecting pipeline, to the first interface, and then enter the cylinder body of the piston structure. And the driving substance in the upper part of the cylinder body flows back to the energy storage device through the second interface and the substance return port. This entire process generates pressure on the piston to drive the piston to move upward along the length direction of the cylinder body, causing the piston rod to extend, thereby pushing the corresponding buffer plate to move towards the inside of the cargo compartment from the initial position. In this way, the gap distance between the buffer plate and the side wall of the cargo compartment increases, forming a larger buffer space to absorb the kinetic energy generated by the cargo due to inertia.

[0089] Further, after buffering is completed, when the vehicle returns to a stable state, the controller can adjust the control valve so that the driving substance in the energy storage device is charged into the cylinder through the second interface, and the driving substance at the bottom of the piston is released to the energy storage device through the first interface, driving the piston to move towards the bottom of the cylinder, causing the corresponding buffer plate to move towards the outside of the cargo compartment to return to the initial position and prepare for the next buffering.

[0090] In some embodiments, the acceleration threshold, deflection angle threshold, and inclination threshold can be set according to various factors such as the dynamic characteristics of the vehicle, the characteristics of the goods, and the vehicle operating environment, and no specific limitations are provided here.

[0091] In some embodiments, according to the condition that the goods in the cargo compartment generate kinetic energy satisfied by the vehicle, controlling the buffer plate at the corresponding side wall position in the cargo compartment to move from the initial position into the cargo compartment includes: when the vehicle generates an acceleration and the value of the acceleration exceeds the acceleration threshold in the acceleration direction, controlling the buffer plate at the position opposite to the acceleration direction to move from the initial position into the cargo compartment.

[0092] Specifically, when the vehicle generates an acceleration and the acceleration value exceeds the acceleration threshold in the acceleration direction, the goods in the vehicle will generate a displacement in the direction opposite to the acceleration direction due to inertia. To reduce the collision force between the goods and the side wall of the cargo compartment caused by inertial displacement, by controlling the buffer plate at the position opposite to the acceleration direction to move from the initial position into the cargo compartment, the distance between the buffer plate and the side wall of the cargo compartment can be increased, and this adjustment provides a larger buffering space for the goods. When the goods hit the buffer plate due to inertia, the buffer plate effectively absorbs the kinetic energy generated by the impact of the goods through its own elastic deformation and the larger buffering space, thereby reducing the risk of damage to the goods and improving the safety and stability during the transportation of the goods.

[0093] In some embodiments, when the vehicle generates an acceleration and the value of the acceleration exceeds the acceleration threshold in the acceleration direction, controlling the buffer plate at the position opposite to the acceleration direction to move from the initial position into the cargo compartment includes: when the vehicle generates a backward acceleration (such as sudden braking, frontal collision) and the value of the acceleration exceeds the acceleration threshold in the acceleration direction, the goods generate a relative forward displacement in the cargo compartment due to inertia. The system controls the piston rod connected to the front buffer plate to extend, so as to control the front buffer plate in the cargo compartment to move from the initial position into the cargo compartment. Taking the vehicle traveling direction as the front, that is, pushing the front buffer plate to move in the direction opposite to the vehicle traveling direction, thereby increasing the distance between the front buffer plate and the front wall of the cargo compartment and more effectively absorbing the kinetic energy generated when the goods move forward and reducing the impact force generated by the impact of the goods.

[0094] Alternatively, when the vehicle generates a leftward acceleration and the value of the acceleration exceeds the acceleration threshold in the acceleration direction, the right buffer plate in the cargo compartment is controlled to move into the cargo compartment from the initial position. Specifically, when a collision occurs on the right side of the vehicle, the acceleration sensor on the side of the vehicle detects a leftward acceleration. When the value of the acceleration exceeds the acceleration threshold in the acceleration direction, the cargo generates a relative displacement to the right of the cargo compartment due to inertia. The system sends a signal to the energy storage tank to open the inlet pipeline of the piston rod connected to the right buffer plate, and releases high-pressure gas or liquid to the piston rod connected to the right buffer plate, so as to push the piston rod connected to the right buffer plate to extend, thereby controlling the right buffer plate in the cargo compartment to move into the cargo compartment from the initial position, increasing the distance between the right buffer plate and the right side wall of the cargo compartment, more effectively absorbing the kinetic energy generated when the cargo moves to the right, and reducing the impact force generated by the cargo collision.

[0095] Alternatively, when the vehicle generates a rightward acceleration and the value of the acceleration exceeds the acceleration threshold in the acceleration direction, the left buffer plate in the cargo compartment is controlled to move into the cargo compartment from the initial position. Specifically, when a collision occurs on the left side of the vehicle, the acceleration sensor on the side of the vehicle detects a rightward acceleration. When the value of the acceleration exceeds the acceleration threshold in the acceleration direction, the cargo generates a relative displacement to the left of the cargo compartment due to inertia. The system sends a signal to the energy storage tank to open the inlet pipeline of the piston rod connected to the left buffer plate, and releases high-pressure gas or liquid to the piston rod connected to the left buffer plate, so as to push the piston rod connected to the left buffer plate to extend, thereby controlling the left buffer plate in the cargo compartment to move into the cargo compartment from the initial position, increasing the distance between the left buffer plate and the left side wall of the cargo compartment, more effectively absorbing the kinetic energy generated when the cargo moves to the left, and reducing the impact force generated by the cargo collision.

[0096] Alternatively, when the vehicle generates a forward acceleration (such as sudden acceleration or being rear-ended) and the value of the acceleration exceeds the acceleration threshold in the acceleration direction, the cargo generates a relative displacement to the rear of the cargo compartment due to inertia. The system controls the piston rod connected to the rear buffer plate to extend, so as to control the rear buffer plate in the cargo compartment to move into the cargo compartment from the initial position, that is, to push the front buffer plate in the direction of the vehicle's travel, thereby increasing the distance between the rear buffer plate and the rear wall of the cargo compartment, more effectively absorbing the kinetic energy generated when the cargo moves backward, and reducing the impact force generated by the cargo collision.

[0097] In some embodiments, according to the conditions for the cargo in the cargo compartment of the vehicle to generate kinetic energy, controlling the buffer plate at the corresponding position in the cargo compartment to move into the cargo compartment from the initial position includes: when the vehicle generates a deflection and the deflection angle exceeds the deflection angle threshold, controlling the buffer plate at the position in the direction opposite to the vehicle's deflection direction to move into the cargo compartment from the initial position; or when the vehicle generates a roll angle and the value of the roll angle exceeds the roll angle threshold, controlling the buffer plate at the position in the same direction as the vehicle's roll direction to move into the cargo compartment from the initial position.

[0098] Specifically, when the vehicle does not collide and makes a sharp right turn or deflection, the goods will have a relative displacement to the left due to inertia. At this time, the yaw angle sensor can detect the deflection angle of the vehicle, and when the deflection angle exceeds the deflection angle threshold, the system sends a signal to the energy storage tank to open the inlet pipeline of the piston rod connected to the left buffer plate, releasing high-pressure gas or liquid to the piston rod connected to the left buffer plate to push the piston rod connected to the left buffer plate to extend, thereby controlling the left buffer plate in the cargo compartment to move from the initial position into the cargo compartment, that is, pushing the left buffer plate towards the right side of the cargo compartment, increasing the distance between the left buffer plate and the left side wall of the cargo compartment, more effectively absorbing the kinetic energy generated when the goods move to the left, and reducing the impact force generated by the impact of the goods.

[0099] Alternatively, when the vehicle does not collide and makes a sharp left turn or deflection, the goods will have a relative displacement to the right due to inertia. At this time, the yaw angle sensor can detect the deflection angle of the vehicle, and when the deflection angle exceeds the deflection angle threshold, the system sends a signal to the energy storage tank to open the inlet pipeline of the piston rod connected to the right buffer plate, releasing high-pressure gas or liquid to the piston rod connected to the right buffer plate to push the piston rod connected to the right buffer plate to extend, thereby controlling the right buffer plate in the cargo compartment to move from the initial position into the cargo compartment, that is, pushing the right buffer plate towards the left side of the cargo compartment, increasing the distance between the right buffer plate and the right side wall of the cargo compartment, more effectively absorbing the kinetic energy generated when the goods move to the right, and reducing the impact force generated by the impact of the goods.

[0100] Alternatively, when the vehicle experiences a left roll, the roll sensor of the vehicle can detect the change in the roll angle of the vehicle. When the value of the roll angle exceeds the roll angle threshold, the system sends a signal to the energy storage tank to open the inlet pipeline of the piston rod connected to the left buffer plate, releasing high-pressure gas or liquid to the piston rod connected to the left buffer plate to push the piston rod connected to the left buffer plate to extend, thereby controlling the left buffer plate in the cargo compartment to move from the initial position into the cargo compartment, increasing the distance between the left buffer plate and the left side wall of the cargo compartment, more effectively absorbing the kinetic energy generated when the goods move to the left, and reducing the impact force generated by the impact of the goods.

[0101] Alternatively, when the vehicle experiences a right roll, the roll sensor of the vehicle can detect the change in the roll angle of the vehicle. When the value of the roll angle exceeds the roll angle threshold, the system sends a signal to the energy storage tank to open the inlet pipeline of the piston rod connected to the right buffer plate, releasing high-pressure gas or liquid to the piston rod connected to the right buffer plate to push the piston rod connected to the right buffer plate to extend, thereby controlling the right buffer plate in the cargo compartment to move from the initial position into the cargo compartment, increasing the distance between the right buffer plate and the right side wall of the cargo compartment, more effectively absorbing the kinetic energy generated when the goods move to the right, and reducing the impact force generated by the impact of the goods.

[0102] In some embodiments, the control method of the cargo compartment buffer device further includes: when the vehicle no longer meets the conditions for the cargo in the cargo compartment to generate kinetic energy, controlling the buffer plate at the corresponding position in the cargo compartment to move out of the cargo compartment to return to the initial position. This reset mechanism can effectively prevent the buffer plate from occupying the effective loading space inside the cargo compartment for a long time, ensuring that the loading volume of the cargo compartment is not affected.

[0103] In some embodiments, when the items in the cargo compartment are relatively full, the cargo compartment buffer device will enter a non-operating state, and the buffer plate will maintain its initial position in the cargo compartment. At this time, the buffer plate can provide a certain degree of buffer protection through its own elastic deformation to avoid occupying the effective space inside the cargo compartment during normal transportation. This design helps to ensure that the loading volume in the cargo compartment remains maximized during transportation while reducing unnecessary activation and energy consumption of the cargo compartment buffer device.

[0104] In some embodiments, the control method of the cargo compartment buffer device further includes: obtaining the distance information between the target cargo generating kinetic energy and the target buffer plate, determining the target moving distance of the piston in the target piston structure corresponding to the target buffer plate according to the distance information, and controlling the rotational speed of the pump body in the energy storage device according to the target moving distance to control the flow rate of the driving substance at the material outlet of the energy storage device.

[0105] Among them, the distance information may refer to the spatial distance between the target cargo and the target buffer plate, which is a key parameter for judging the buffer demand and the displacement of the target piston. The distance information can be measured by various sensors, such as ultrasonic sensors, infrared sensors, millimeter-wave radars, etc.

[0106] In some embodiments, the target moving distance may refer to the distance that the piston needs to move to ensure that the buffer plate can effectively absorb the kinetic energy of the cargo and prevent the cargo from colliding with the buffer plate. The purpose of determining the target moving distance according to the distance information is to accurately adjust the movement of the target buffer plate under different driving states to adapt to different moving states of the cargo.

[0107] Next, refer to Figure 7 Describe the vehicle according to an embodiment of the present invention.

[0108] Figure 7 is a block diagram of a vehicle according to an embodiment of the present invention, as Figure 7 shown, the vehicle 100 includes: a cargo compartment 2, a detection device 3, and the cargo compartment buffer device 1 described in the above embodiments.

[0109] In some embodiments, the cargo compartment 2 is an enclosed space inside the vehicle 100 for storing and transporting goods, and can be located at the rear of the vehicle 100. In different types of vehicles 100, the design of the cargo compartment 2 may be different, such as trucks, freight vehicles, vans, etc. The size, shape, and internal configuration of the cargo compartment 2 depend on the type and intended use of the vehicle 100.

[0110] In some embodiments, the detection device 3 is an electronic device for detecting vehicle operating state information, and feeds this information back to the controller of the cargo compartment buffer device for analysis and processing. The detection device 3 may include in-vehicle sensors and / or the advanced driver assistance system 34 of the vehicle 100.

[0111] Among them, the in-vehicle sensors are various sensors installed on the vehicle, responsible for detecting the operating state of the vehicle in real time. As Figure 3 shown, the in-vehicle sensors may include: an acceleration sensor 31, a yaw rate sensor 32, a roll sensor 33, etc. Among them, as Figure 4 shown, the acceleration sensor 31 may be installed on the front bumper beam and the side panels of the vehicle, and is used to measure the linear acceleration or deceleration of the vehicle 100 to determine whether the vehicle 100 is in a situation of sudden acceleration or sudden deceleration. The yaw rate sensor 32 may be installed in the middle of the vehicle chassis and is used to measure the deflection angle of the vehicle 100 around the vertical axis, and can determine whether the vehicle 100 is in a situation of sharp turning. The roll sensor 33 may be used to measure the roll angle of the vehicle 100 around the transverse axis, and can determine whether the vehicle 100 is in a situation of collision or rollover.

[0112] In some embodiments, as Figure 3 shown, the advanced driver assistance system 34 can detect the motion state of the vehicle 100 in real time through sensors such as lidar, millimeter wave radar or cameras. When the system detects sudden braking or sharp turning, the sensor data will be transmitted to the controller 4. The controller 4 judges whether it is necessary to adjust the cargo compartment buffer device 1 based on this information to ensure the safety of the goods.

[0113] In some embodiments, the cargo compartment buffer device 1 is installed inside the cargo compartment 2 and is a device for reducing or absorbing the kinetic energy generated by the displacement of the goods during transportation. It may include a plurality of buffer plates 11, a piston structure 122, an energy storage device 121, etc., and can adjust the position of the buffer plates 11 when the vehicle 100 is in sudden acceleration, sudden braking, sharp turning, rollover or collision with other vehicles, so as to absorb the impact energy generated by the impact of the goods by increasing the distance between the buffer plates 11 and the side walls of the cargo compartment.

[0114] In some embodiments, the controller of the cargo compartment buffer device is connected to the detection device 3, and the controller is also used to execute the control method of the cargo compartment buffer device described in the above embodiments.

[0115] Vehicle 100 according to an embodiment of the present invention, the controller of the cargo compartment buffer device 1 is connected to the detection device 3. The detection device 3 can detect the vehicle operation state information in real time and transmit this information to the controller in the cargo compartment buffer device 1, so that the controller can, according to the dynamic operation of the vehicle 100, adopt the control method of the cargo compartment buffer device described in the above embodiment. When the vehicle 100 meets the condition that the goods in the cargo compartment 2 generate kinetic energy, control the buffer plate 11 at the corresponding side wall position in the cargo compartment 2 to move from the initial position into the cargo compartment 2, that is, move in the opposite direction of the cargo compartment side wall. In this way, before the goods have inertial displacement, the active adjustment of the position of the buffer plate 11 can be realized, increasing the distance between the buffer plate 11 and the cargo compartment side wall, enabling the goods to have a greater buffer distance under the action of inertia, and further more effectively absorbing the impact energy generated by the impact of the goods due to inertia, thereby playing a role in shock absorption and protecting the goods, reducing the risk of damage to the goods, and improving the transportation efficiency of the vehicle 100 and the safety of the goods.

[0116] Reference will be made below to Figure 8 describe an electronic device according to an embodiment of the present invention.

[0117] Figure 8 is a block diagram of an electronic device 200 according to an embodiment of the present invention, as Figure 8 shown, the electronic device 200 includes: a memory 202 and at least one processor 201.

[0118] In some embodiments, the processor 201 is the core component for executing computing tasks. It can be a central processing unit (CPU, Central Processing Unit), a graphics processing unit (GPU, Graphic Processing Unit), or a digital signal processor (DSP, Digital Signal Process). The processor 201 is responsible for executing the computer program stored in the memory 202 and controlling the operation of the cargo compartment buffer device 1 of the vehicle. By processing the data from sensors in real time (such as acceleration, deflection angle, roll angle, etc.), it decides when to control the movement of the buffer plate 11. The at least one processor 201 can be one processor 201, or multiple processors 201 such as two processors 201, three processors 201, five processors 201, etc. The processor 201 can be a single-core or multi-core processor 201. It specifically depends on the design and use of the electronic device 200.

[0119] In some embodiments, the memory 202 is used to store computer programs and the data required for their operation. It can be a read-only memory (ROM) or a random access memory (RAM). The program code in the memory 202 instructs the processor 201 on how to control the cargo compartment buffer device 1 according to the state of the vehicle 100. The data in the memory 202 also includes key control parameters such as sensor inputs, acceleration thresholds, deflection angle thresholds, and inclination thresholds.

[0120] In some embodiments, the memory 202 is communicatively connected to at least one processor 201. A computer program executable by the at least one processor 201 is stored in the memory 202. When the at least one processor 201 executes the computer program, the control method of the cargo compartment buffer device described in the above embodiments is implemented.

[0121] According to the electronic device 200 of the embodiment of the present invention, when the at least one processor 201 executes the computer program for implementing the control method of the cargo compartment buffer device described in the above embodiments, when the vehicle 100 meets the condition that the goods in the cargo compartment 2 generate kinetic energy, it can control the buffer plate 11 at the corresponding side wall position in the cargo compartment 2 to move from the initial position into the cargo compartment, that is, move in the opposite direction of the cargo compartment side wall. In this way, before the goods undergo inertial displacement, the active adjustment of the position of the buffer plate 11 can be realized, increasing the distance between the buffer plate 11 and the cargo compartment side wall, enabling the goods to have a greater buffer distance under the action of inertia, and thus more effectively absorbing the impact energy generated by the impact of the goods due to inertia, thereby playing a role in shock absorption and protecting the goods, reducing the risk of damage to the goods, and improving the transportation efficiency of the vehicle 100 and the safety of the goods.

[0122] The embodiment of the present invention also proposes a computer-readable storage medium, on which a computer program is stored. When the computer program is executed, the control method of the cargo compartment buffer device described in the above embodiments is implemented. The specific implementation process of the control method of the cargo compartment buffer device can refer to the description of the above embodiments.

[0123] In some embodiments, the non-volatile readable storage medium may include, but is not limited to, phase change memory (PRAM), static random access memory (SRAM), dynamic random access memory (DRAM), other types of random access memory (RAM), read-only memory (ROM), electrically erasable programmable read-only memory (EEPROM), flash memory, or other optical and magnetic storage media, which will not be elaborated here one by one.

[0124] According to the computer-readable storage medium of the embodiment of the present invention, by adopting the control method of the cargo compartment buffer device described in the above embodiment, the position movement of the buffer plate 11 is realized, so that the distance between the buffer plate 11 and the side wall of the cargo compartment is controllable, and a greater buffer distance can be provided for the goods during impact, thereby more effectively absorbing the kinetic energy of the goods hitting the cargo compartment 2 due to inertia, playing a protective role for the goods, reducing the risk of damage to the goods, and thus improving the transportation efficiency of the vehicle 100 and the safety of the goods.
