Description

Technical Field

[0001] This invention relates to the field of airport support equipment technology, and in particular to a dedicated unmanned multi-operation mode support vehicle for airports. Background Technology

[0002] Airport support vehicles are a general term for various specialized vehicles and equipment used to ensure the normal operation of aircraft. They include various types of vehicles such as road sweepers and snowplows. Snow removal on airport roads is very different from that on ordinary city roads and has higher requirements. Hot air blowers are the "trump card" for runway snow removal. They are usually modified from aircraft engines and can spray high-speed hot air at 800-1000℃ to instantly blow away and evaporate snow and ice. They are extremely efficient, but their fuel consumption is also astonishing. Snow sweeping methods are difficult to deal with already icy roads. Vibratory ice breakers cause relatively less damage to the road surface and have a more uniform breaking effect. They are often used in airports or important roads with high requirements for pavement.

[0003] A search revealed a Chinese invention patent with application number CN202010760160.1, which discloses a de-icing engineering vehicle. The vibrator on the ice-breaking bracket operates, and its vibrating component can perform high-frequency vibration in the radial direction of the rotating shaft. The high-frequency vibration of the vibrating component breaks the ice surface for removal, ensuring the safety of vehicle operation.

[0004] In order to ensure that the vibrator is in contact with the ice surface, the above-mentioned device requires the vibrator to be pressed against the ice surface. However, it is difficult to control the force of the vibrator pressing against the ice surface, which can easily lead to excessive force pressing against the ice surface and causing damage to the road surface. Moreover, if there are foreign objects on the road surface that have not been cleaned up, it is easier for foreign objects to accumulate into the road surface and cause damage to the road surface. Summary of the Invention

[0005] One objective of this invention is to propose an unmanned multi-operation mode support vehicle specifically for airports. This invention can control the force of the vibrator pressing on the road surface, avoiding excessive force from the vibrator pressing on the road surface and causing road damage. It can also reduce the possibility of foreign objects that have not been cleaned on the road surface being squeezed into the road surface and causing road damage.

[0006] According to an embodiment of the present invention, an unmanned multi-operation mode support vehicle for airports includes a vehicle body, a control box installed on the vehicle body, a vibration de-icing component for elastically contacting the road surface at the bottom of the vehicle body, a traction component for lowering the vibration de-icing component between the vehicle body and the vibration de-icing component, and a support component for accommodating cargo loading space at the top of the vehicle body. The vibration de-icing assembly includes multiple contact plates, with notches at opposite ends of adjacent contact plates, and a crossbeam passing through the notches between the contact plates. A vibration motor is fixedly connected to the top of the crossbeam, and a separator is provided at the bottom of the contact plates to separate the bottom of the contact plates from the road surface. The separating component includes a rubber ball that runs longitudinally through the contact plate, a receiving cavity that runs through the top of the rubber ball, a metal ball that is fixed to the rubber ball at the bottom of the receiving cavity, and an air inlet pipe that communicates with the receiving cavity at the top of the rubber ball.

[0007] Furthermore, the contact plate includes a central flat plate segment, with arc plate segments connected to both ends of the flat plate segment, and a rubber ball fixed to the flat plate segment.

[0008] Furthermore, the flat plate segment includes multiple horizontal plates and long rods. The end of the long rod along the vehicle body moving direction is fixed to the arc plate segment, and the front end of the long rod along the vehicle body moving direction extends movably into the arc plate segment. The horizontal plates slide along the long rods. When the rubber ball is squeezed by the contact plate, it deforms and pushes the horizontal plate to slide along the long rods. After the horizontal plate moves, it generates a pulling force on the bottom contact surface.

[0009] Furthermore, an arc-shaped block adapted to the curvature of the metal ball is fixedly connected to the bottom of the air intake pipe, and a bolt penetrating the top of the arc-shaped block is provided.

[0010] Furthermore, the metal sphere has vents on both sides, a longitudinal groove on the top, and dispersed exhaust ports communicating with the longitudinal groove on both sides.

[0011] Furthermore, an annular pipe is connected between the air intake pipes, and a flexible hose is connected to one side of the annular pipe, which is connected to the air source device in the control box.

[0012] Furthermore, the traction assembly includes a receiving frame fixed to the top of the vehicle body, a winding frame fixed to the vehicle body is provided inside the receiving frame, a motor is fixedly connected to one side of the winding frame, and a traction rope passing through the vehicle body is connected between the winding frame and the crossbeam.

[0013] Furthermore, a limiting tube adapted to the traction rope is fixedly connected to the bottom of the vehicle body, the traction rope passes through the limiting tube, and an inner rod adapted to the limiting tube is provided at the top of the cross frame, with the bottom of the traction rope fixed to the inner rod.

[0014] Furthermore, the support assembly includes a limiting frame fixed to the top of the vehicle body, a notch adapted to the limiting frame is provided on the top of the vehicle body, a lifting block that slides along its inner wall is provided on the top of the limiting frame, a support plate is fixedly connected to the top of the lifting block, and a spring is fixedly connected to the bottom of the lifting block.

[0015] Furthermore, a longitudinal frame is fixedly connected to the bottom of the vehicle body, and a crossbar for limiting the bottom of the spring is provided inside the longitudinal frame, with the projection of the spring on the horizontal plane onto the crossbar.

[0016] The beneficial effects of this invention are: This invention, through its vibratory de-icing component, enables unmanned vehicles to operate in multiple modes, including cargo transport, clearing road debris, and de-icing. Utilizing a rubber ball spaced between the vibrator and the road surface, even with strong pressure from the vibrator, the rubber ball remains relatively thin and does not directly contact the road surface, maintaining a gap. Contact with the road surface occurs only when the vibrator vibrates and causes displacement, allowing for effective de-icing. This control over the force exerted by the vibrator on the road surface during de-icing prevents excessive pressure and road damage. The combination of vibration de-icing and high-temperature airflow melting reduces the possibility of unbroken ice. Furthermore, the blowing of debris from the road surface prevents it from being forced into the road and causing damage.

[0017] This invention utilizes a retractable contact plate structure to generate lateral thrust on the ice layer, causing it to break laterally. Combined with the longitudinal impact generated by the vibration of the contact plate driven by a vibrating motor, forces are applied to the ice layer from multiple directions simultaneously, increasing the speed and effectiveness of ice breaking. This also reduces the force required to break the ice layer longitudinally, further minimizing damage to the road surface during ice breaking. This invention can meet the de-icing requirements of locations with higher road surface standards.

[0018] This invention, through the use of arc-shaped blocks and bolts, can flexibly adjust the degree of damage to the ice layer on the road surface by squeezing it according to the thickness of the ice layer. When the ice layer on the road surface thickens, the pressure squeezed towards the road surface is increased. Since the ice layer is thicker, the damage to the road surface during squeezing is also smaller. Before the ice layer on the road surface is broken by vibration, the ice layer is cracked by squeezing, which accelerates the breaking speed of the ice layer. It can adapt to the de-icing needs of thick ice on the road surface in extreme weather.

[0019] This invention, through the design of a traction component, a limiting tube, and an inner rod, flexibly connects the vibrating motor and contact plate (acting as a vibrator) to the vehicle body when clearing foreign objects and ice from the road surface. This reduces damage to the connection between the vibrating de-icing component and the vehicle body during the vibration process. At the same time, when road surface clearing is not required, it increases the limiting of the vibrating motor and contact plate (acting as a vibrator) to prevent the contact plate from shaking and improves the stability of the vibrating de-icing component when the vehicle body is moving.

[0020] This invention utilizes a support plate, spring, and crossbar. The spring and the cargo on the support plate also play a mutually supportive role. When cargo is placed on the support plate, the cargo pushes the support plate down, compressing the spring to provide cushioning and reduce damage to the vehicle body during cargo placement. The weight of the cargo also pushes the spring to further compress the contact plate, providing greater thrust to the contact plate to deform the rubber ball and bring it closer to the ice layer on the road surface. This prevents the rubber ball from being deformed to a sufficient degree by relying solely on the weight of the contact plate, crossbar, and vibration motor. Attached Figure Description

[0030] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the invention, and therefore only show the components relevant to the invention.

[0031] refer to Figures 1-9 The system includes a vehicle body 1, a control box 2 mounted on the vehicle body 1, a vibratory de-icing assembly 3 for elastic contact with the road surface at the bottom of the vehicle body 1, a traction assembly 4 for lowering the vibratory de-icing assembly 3 between the vehicle body 1 and the vibratory de-icing assembly 3, and a support assembly 5 for accommodating cargo loading space at the top of the vehicle body 1. The vibratory de-icing assembly 3 includes multiple contact plates 31, with notches at opposite ends of adjacent contact plates 31, and a crossbeam 32 passing through the notches between the contact plates 31. A vibratory motor 33 is fixedly connected to the top of the crossbeam 32, and a separating assembly 34 separating the bottom of the contact plates 31 from the road surface at the bottom of the contact plates 31. The separating assembly 34 includes a longitudinally penetrating joint. The touch plate 31 has a rubber ball 341. The top of the rubber ball 341 has a cavity 342 that penetrates the rubber ball 341. The bottom of the cavity 342 has a metal ball 343 that is fixed to the rubber ball 341. The top of the rubber ball 341 has an air inlet pipe 344 that communicates with the cavity 342 and supplies air into the rubber ball 341. The metal ball 343 has vents on both sides and a longitudinal groove on its top. The metal ball 343 has dispersed exhaust ports on both sides that communicate with the longitudinal groove. The air inlet pipes 344 are connected by an annular pipe 8. A hose 9 is connected to one side of the annular pipe 8 and is connected to the air source device in the control box 2.

[0032] In this implementation scheme, the control box 2 controls the vehicle body 1, similar to existing inspection robots, and features intelligent recognition, communication, and intelligent path planning. It is equipped with an air source device and a heater. The air source device is an air pump, and the hose 9 is connected to the air pump inside the control box 2. High-temperature air or normal-temperature air is delivered to the rubber ball 341 as needed. Since it is existing technology, the specific process of the control box 2 controlling the vehicle body 1 will not be described in detail in this embodiment. The vehicle body 1 can achieve the function of unmanned operation. Luggage and other goods can be placed on the support component 5, so that the support vehicle can realize the function of cargo transportation. The traction component 4 drives the vibration de-icing component 3 to descend and contact the ground, or to be separated from the ground by a certain distance, so that the vibration de-icing component 3 can realize different functions including vibration de-icing.

[0033] Specifically, the traction component 4 releases the vibration de-icing component 3 downwards, so that the vibration de-icing component 3 has two different working modes: contact with the ground and no contact with the ground. The air intake pipe 344 also delivers high-temperature air or normal-temperature air into the rubber ball 341 according to the different working modes.

[0034] When the vibratory de-icing component 3 contacts the ground, its own weight compresses the rubber ball 341, deforming it. After the rubber ball 341 is compressed, the contact plate 31 gradually approaches the road surface until a small gap exists between the contact plate 31 and the road surface. The vibration motor 33 then starts, causing the contact plate 31 to vibrate. During vibration, the contact plate 31 undergoes a small displacement, contacting the road surface with the previously small gap, transmitting the vibration to the ice surface and performing vibratory de-icing. The air intake pipe 344 directs air to the rubber ball 341... High-temperature air is supplied inside the 41. The high-temperature air is discharged from the vent and dispersed exhaust port on the side of the metal ball 343 to the ice layer on the road surface below. The high temperature melts part of the ice, reducing the difficulty of the ice layer on the road surface being broken by vibration. The airflow can also blow away foreign objects that have fallen on the road surface. Due to the presence of the rubber ball 341 between the contact plate 31 and the road surface, even if the vibrating end is squeezed towards the road surface with great force before vibration de-icing, it will be blocked by the rubber ball 341 and will not directly contact the road surface, thus avoiding excessive pressure on the road surface caused by the vibrator.

[0035] When the vibratory de-icing assembly 3 is not in contact with the ground, the vibratory motor 33 is not in contact with the road surface. At this time, no de-icing work is performed on the road surface. Only foreign objects that have fallen on the road surface are blown away. Only the air inlet pipe 344 delivers room temperature air at high speed into the rubber ball 341. The high-speed flow of room temperature air is discharged from the air vent and the dispersed exhaust port on the side of the metal ball 343 to the road surface below, blowing the foreign objects on the road surface to both sides of the road surface, thus completing the work of cleaning up the debris on the road surface.

[0036] Combining the two different working modes, the unmanned support vehicle possesses multiple operational modes, including cargo transportation, road debris removal, and road de-icing. Utilizing the rubber ball 341 spaced between the vibrator and the road surface, even with strong pressure from the vibrator, the rubber ball 341 remains relatively thin and does not directly contact the road surface, maintaining a gap. It only contacts the road surface for de-icing when the vibrator vibrates and causes displacement. This allows for control over the force exerted by the vibrator on the road surface during de-icing, preventing excessive pressure that could damage the road. Combining vibration de-icing with high-temperature airflow melting during de-icing reduces the possibility of unbroken ice. Furthermore, blowing away debris from the road surface prevents it from being squeezed into the road and causing damage.

[0037] Reference Figures 1-3 The contact plate 31 includes a middle flat plate segment 311, with arc plate segments 312 connected to both ends of the flat plate segment 311. A rubber ball 341 is fixed to the flat plate segment 311. The flat plate segment 311 includes multiple horizontal plates 3111 and a long rod 3112. The end of the long rod 3112 along the moving direction of the vehicle body 1 is fixed to the arc plate segment 312. The front end of the long rod 3112 along the moving direction of the vehicle body 1 extends movably into the arc plate segment 312. The horizontal plates 3111 slide along the long rod 3112. The rubber ball 341 is fixed on both sides of the horizontal plates 3111. When the rubber ball 341 is squeezed by the contact plate 31, it deforms and pushes the horizontal plates 3111 to slide along the long rod 3112. After the horizontal plates 3111 move, they generate a pulling force on the bottom contact surface.

[0038] In this embodiment, the contact plate 31 is configured to be telescopic, which can extend in the forward direction of the vehicle body 1 when squeezed, and generate a lateral pulling force on the road surface when in contact with the road surface, so as to pull and break the ice layer on the road surface, and improve the breaking effect of the ice layer on the road surface in conjunction with the vibrator.

[0039] Specifically, as the traction component 4 releases the vibration de-icing component 3 downwards, the vibration de-icing component 3 gradually approaches the road surface until the rubber ball 341 at the bottom of the contact plate 31 contacts the road surface. The gravity of the contact plate 31, the crossbeam 32 above it, and the vibration motor 33 pushes the rubber ball 341 to squeeze the road surface, deforming the rubber ball 341 from its original spherical shape to a horizontal flat shape. Figure 3The horizontal plate 3111 and the left-side arc plate segment 312 are pushed to the left along the long rod 3112, increasing the overall length of the contact plate 31. As the contact plate 31 vibrates, driven by the vibrating motor 33, it continuously contacts the ice layer on the road surface. When the contact plate 31 extends horizontally, it also contacts the ice layer on the road surface, generating friction and pushing the ice layer to form a lateral thrust, causing the ice layer on the road surface to crack laterally. When the traction component 4 pulls the vibrating de-icing component 3 up and no longer contacts the road surface, the rubber ball 341 gradually returns to its original shape under its own elasticity. Pull the horizontal plate 3111 and the left arc plate segment 312 to the right to the initial position, so that the contact plate 31, which was originally extended in the horizontal direction, returns to its initial length. When the contact plate 31 vibrates in conjunction with the vibration motor 33, it causes longitudinal collision with the road surface ice layer. It applies force to the road surface ice layer from multiple different directions at the same time, which improves the speed and effect of breaking the road surface ice layer. At the same time, it reduces the force required to break the road surface ice layer in the longitudinal direction, further reducing the damage to the road surface when breaking the road surface ice layer. It can meet the de-icing requirements of places with higher road surface standards.

[0040] After the rubber ball 341 deforms the road surface by squeezing it, it pushes the contact plate 31 to extend as a whole. This increases the gap between the horizontal plates 3111, which in turn moves the foreign objects that were originally between the horizontal plates 3111. The foreign objects that were originally squeezed at the bottom of the horizontal plates 3111 are also blown away by the air blown out from the bottom of the rubber ball 341 when the horizontal plates 3111 move. This increases the possibility that the foreign objects squeezed onto the road surface by the contact plate 31 will be blown away, thereby reducing the possibility that there are foreign objects between the contact plate 31 and the road surface, which could cause the contact plate 31 to squeeze the foreign objects toward the road surface and cause road damage.

[0041] Reference Figures 1-4 The bottom of the intake pipe 344 is fixedly connected to an arc-shaped block 6 that matches the curvature of the metal ball 343, and the top of the arc-shaped block 6 is provided with a bolt 7 that passes through the arc-shaped block 6.

[0042] In this embodiment, the arc-shaped block 6 and bolt 7 are used to limit the length of the rubber ball 341 and metal ball 343 that can be contracted in the longitudinal direction after being squeezed, thereby controlling the distance between the contact plate 31 and the road surface when there is no vibration, and also controlling the degree of deformation and buffering of the rubber ball 341. When the thickness of the road ice layer increases, the range of deformation and buffering of the rubber ball 341 is reduced, thereby increasing the force of the contact plate 31 squeezing the road surface and directly breaking the road ice layer.

[0043] Specifically, after the bolt 7 is rotated, it rises to the highest point along the arc-shaped block 6. At this time, the bolt 7 does not restrict the movement of the metal ball 343. When the contact plate 31 moves towards the road surface and squeezes the road surface, the contact plate 31 and the road surface squeeze and deform the rubber ball 341. The rubber ball 341 can deform to the maximum extent, so that the gap between the contact plate 31 and the road surface is minimized. At the same time, due to the deformation of the rubber ball 341, the area of ​​the contact plate 31 on the road surface increases, the pressure on the road surface decreases, and therefore the degree of damage to the road surface is minimized.

[0044] When the thickness of the ice layer on the road surface increases, the impact on the road surface when the ice layer is squeezed is relatively small. To accelerate the destruction of the ice layer, the pressure applied to it can be increased. Workers pre-adjust bolt 7 by rotating it and moving it downwards along the arc-shaped block 6. This reduces the longitudinal distance that the metal ball 343 can move after being squeezed, thus reducing the longitudinal deformation of the rubber ball 341 and weakening its buffering capacity. When the contact plate 31, under the weight of itself, the crossbeam 32 above it, and the vibrating motor 33, squeezes the road surface, the contact plate 31 and the road surface deform the rubber ball 341. After the rubber ball 341 deforms and moves a certain distance, it is blocked by bolt 7. At this point, the rubber ball 341 cannot continue to deform before reaching its maximum deformation. Afterwards, the contact plate 31, the crossbeam 32, and the vibrating motor 33... The gravity pushes the rubber ball 341 and the metal ball 343 to squeeze the ice layer on the road surface. As the degree of deformation of the rubber ball 341 decreases, the lateral extension of the contact plate 31 also decreases. Therefore, the contact area between the deformed rubber ball 341 and the contact plate 31 and the road surface is smaller than when the contact plate 31 is fully extended. When squeezing the road surface, the pressure on the road surface per unit area increases, and the ice layer is squeezed and broken more obviously. The degree of damage to the ice layer on the road surface can be flexibly adjusted according to the thickness of the ice layer. When the ice layer on the road surface is thicker, the pressure on the ice layer on the road surface is increased in the direction of the road surface. Since the ice layer is thicker, the damage to the road surface when squeezing is also smaller. Before the ice layer on the road surface is broken by vibration, the ice layer is cracked by squeezing, which accelerates the breaking speed of the ice layer. It can adapt to the de-icing needs of thick ice on the road surface in extreme weather.

[0045] Reference Figures 1-7 The traction assembly 4 includes a receiving frame 41 fixed to the top of the vehicle body 1. A winding frame 42 fixed to the vehicle body 1 is provided inside the receiving frame 41. A motor 43 is fixedly connected to one side of the winding frame 42. A traction rope 44 passing through the vehicle body 1 is connected between the winding frame 42 and the cross frame 32. A limiting tube 10 adapted to the traction rope 44 is fixedly connected to the bottom of the vehicle body 1. The traction rope 44 passes through the limiting tube 10. An inner rod 11 adapted to the limiting tube 10 is provided at the top of the cross frame 32. The bottom of the traction rope 44 is fixed to the inner rod 11.

[0046] In this embodiment, the traction component 4 is used to pull the vibration de-icing component 3 to rise or fall, so that the vibration de-icing component 3 is in different states of contact with the road surface or not in contact with the road surface. This makes it convenient for the vibration de-icing component 3 to vibrate and de-ice the ice layer on the road surface, or to use airflow to blow away foreign objects on the road surface, thus realizing one of the functions of road de-icing or road foreign object removal.

[0047] Specifically, the motor 43 drives the winding rod of the winding frame 42 to rotate, causing the traction rope 44 originally wound on the winding frame 42 to detach from the winding frame 42. Under its own weight, the cross frame 32 pulls the traction rope 44 downward. The cross frame 32 and the contact plate 31 gradually descend. When it is necessary to clear foreign objects from the road surface, the contact plate 31 only needs to descend to a distance from the road surface. At this time, the motor 43 stops working, and the traction rope 44 wound on the winding frame 42 no longer detaches from the winding frame 42. The contact plate 31 can no longer pull the traction rope 44 and descends. At this time, the contact plate 31 is suspended above the road surface. The air source device in the control box 2 delivers room temperature air to the rubber ball 341 through the hose 9 and the annular pipe 8. The air in the rubber ball 341 flows out from different notches on the side of the metal ball 343. The notches on the side of the metal ball 343 in different directions guide the airflow to spray onto the road surface from different directions, expanding the area for clearing foreign objects from the road surface.

[0048] When it is necessary to clear ice from the road surface, the motor 43 continues to drive the winding frame 42 to rotate, causing the contact plate 31 and the rubber ball 341 to continue to descend until the rubber ball 341 is squeezed and deformed on the road surface. The vibrating motor 33 drives the contact plate 31 to vibrate and then contact the ice layer on the road surface to remove ice.

[0049] When road surface cleaning is not required, motor 43 rotates in the reverse direction, winding traction rope 44 onto winding frame 42. Traction rope 44 drives crossbeam 32 and contact plate 31 to rise, and crossbeam 32 drives inner rod 11 to rise until inner rod 11 rises into limit tube 10. Contact plate 31 cannot shake after being limited by limit tube 10 through inner rod 11. At this time, motor 43 stops working. When cleaning foreign objects and ice on the road surface, the vibrating motor 33 and contact plate 31, which act as vibrators, are connected to vehicle body 1 in a flexible manner to reduce the damage to the connection between vibrating de-icing assembly 3 and vehicle body 1 during the vibration process. At the same time, when road surface cleaning is not required, the limit on vibrating motor 33 and contact plate 31, which act as vibrators, is increased to prevent contact plate 31 from shaking and improve the stability of vibrating de-icing assembly 3 when the vehicle body moves.

[0050] Reference Figures 1-9The support component 5 includes a limiting frame 51 fixed to the top of the vehicle body 1. The top of the vehicle body 1 has a notch adapted to the limiting frame 51. The top of the limiting frame 51 has a lifting block 52 that slides along its inner wall. The top of the lifting block 52 is fixedly connected to a support plate 53. The bottom of the lifting block 52 is fixedly connected to a spring 54. The bottom of the vehicle body 1 is fixedly connected to a longitudinal frame 12. The longitudinal frame 12 has a crossbar 13 for limiting the bottom of the spring 54. The projection of the spring 54 on the horizontal plane is on the crossbar 32.

[0051] In this implementation scheme, the support plate 53 is used to accommodate the goods to be transported, providing a cargo transportation operation mode for the support vehicle. At the same time, when it is necessary to increase the tightness of the contact plate 31 with the ice layer on the road surface, the crossbar 13 of the limiting spring 54 can be removed, so that the elastic force of the spring 54 acts on the crossbar 32, pushing the crossbar 32 and the contact plate 31 to squeeze the rubber ball 341 and the road surface downwards, avoiding the insufficient squeezing force when the gravity of the vibration de-icing component 3 is used alone to squeeze the ice layer on the road surface, which affects the breaking effect of the ice layer on the road surface.

[0052] Specifically, during the de-icing process, when the rubber ball 341 is deformed and its contact with the road ice layer is low due to the weight of the contact plate 31, crossbar 32, and vibrating motor 33 alone, the crossbar 13 is removed by the workers. The bottom of the compressed spring 54 extends until the bottom of the spring 54 is blocked by the crossbar 32. The elastic force of the spring 54 pushes the contact plate 31 to deform the rubber ball 341 with greater force, ensuring that the contact plate 31 is close to the road ice layer after the rubber ball 341 is deformed. At the same time, the elastic force pushes the contact plate 31 to deform the rubber ball 341 and then apply it to the road ice layer. The spring 54 and the cargo on the support plate 53 also play a mutually auxiliary role. When the cargo is placed on the support plate 53, the cargo pushes the support plate 53 down, squeezing and compressing the spring 54 to buffer and reduce the damage to the vehicle body 1 when placing the cargo. The weight of the cargo also pushes the spring 54 to further squeeze the contact plate 31, providing a greater thrust to the contact plate 31 to squeeze and deform the rubber ball 341 and bring it closer to the ice layer on the road surface, preventing the rubber ball 341 from being squeezed and deformed to a sufficient degree by the weight of the contact plate 31, the crossbar 32 and the vibration motor 33 alone.
