Technical Field

[0001] The utility model relates to the technical field of automobile safety, in particular to a vehicle with a pedestrian protection function. Background Art

[0002] With the booming automotive industry and the accelerating urbanization process, cars have become an indispensable means of transportation in modern society, and their number continues to surge worldwide. However, this trend is also accompanied by severe traffic challenges, namely, increasingly busy road traffic, a sharp increase in the flow of vehicles and pedestrians, and the interaction between the two has become unprecedentedly complex and dynamic. In the ever-changing traffic environment, the risk of conflict between vehicles and pedestrians has risen sharply, leading to frequent collision accidents, which has become a major factor threatening public safety.

[0003] What is particularly worrying is that when a vehicle collides with a pedestrian, if the pedestrian is unfortunately caught under the vehicle, he or she will often face more serious secondary injuries. This injury not only exacerbates the victim's pain, but also imposes a huge economic and psychological burden on society. Therefore, how to effectively reduce the risk of collision between vehicles and pedestrians, especially how to take quick measures to prevent pedestrians from being caught under the vehicle and suffering secondary injuries when a collision occurs, and protect the lives of pedestrians, has become an urgent problem that needs to be solved in the automotive industry and even the entire society. Utility Model Content

[0004] The purpose of the utility model is to provide a vehicle with a pedestrian protection function to solve the problem in the prior art of how to prevent pedestrians from being rolled under the vehicle and suffering secondary injuries when a collision occurs.

[0005] In order to achieve the above purpose, the technical solution adopted by the present utility model is as follows:

[0006] A vehicle with a pedestrian protection function comprises a vehicle body, two front wheels and two rear wheels being symmetrically mounted on the bottom of the vehicle body, and further comprising:

[0007] An intercepting assembly, the intercepting assembly comprising an intercepting plate and a first driving device, the intercepting plate being rotatably mounted on the bottom of the vehicle body and located in front of the two front wheels, the first driving device being connected to the intercepting plate and configured to drive the intercepting plate to flip;

[0008] A collision detection device, mounted at the front end of the vehicle body, for detecting collision pressure;

[0009] A controller is connected to the first drive device and the collision detection device respectively, and is configured to control the first drive device to drive the interception plate to flip from a state parallel to the vehicle bottom plate to a state perpendicular to the vehicle bottom plate according to the collision pressure signal detected by the collision detection device, so as to prevent pedestrians from being caught under the vehicle.

[0010] According to the above technical means, the interception plate is driven to flip downward by the first drive device to realize the function of intercepting or blocking under the vehicle, preventing pedestrians from being rolled under the vehicle, and enhancing driving safety. Specifically, during a collision, when the collision detection device detects the collision pressure between the pedestrian and the vehicle body, the controller can respond quickly according to the collision pressure signal to control the first drive device to drive the interception plate to flip downward, that is, flip from a state parallel to the vehicle body bottom plate to a state perpendicular to the vehicle body bottom plate, and realize the function of intercepting or blocking under the vehicle, thereby preventing the struck pedestrian from being rolled under the vehicle, avoiding or reducing secondary injuries, and after the blocking is completed, the controller controls the first drive device to drive the interception plate to flip upward to reset. During this process, the interception plate also has a tendency to push the struck pedestrian away from the bottom of the vehicle, which facilitates rescue, reduces the degree of injury to pedestrians in the accident, and protects the lives of pedestrians and driving safety.

[0011] Furthermore, the intercepting plate includes a hollow main plate and a sub-plate, one end of the hollow main plate is rotatably mounted on the bottom of the vehicle body, the other end of the hollow main plate is slidingly fitted with one end of the sub-plate, the other end of the sub-plate is connected to the first driving device, and the sub-plate is configured so that when the hollow main plate is parallel to the vehicle body bottom plate, the sub-plate shrinks inside the hollow main plate; when the hollow main plate is perpendicular to the vehicle body bottom plate, the sub-plate extends out of the hollow main plate.

[0012] According to the above technical means, the interception plate composed of the hollow main plate and the sub-plate slidingly fitted together can freely extend and retract when flipped to adapt to vehicle models of different heights, thereby improving the flexibility and efficiency of the bottom protection of the vehicle body. When the vehicle is in normal driving state, the hollow main plate remains parallel to the bottom of the vehicle body, and the sub-plate shrinks inside the hollow main plate, which not only reduces air resistance but also maintains the overall aesthetics of the vehicle body. In an emergency situation where it is necessary to intercept or block the struck pedestrian or object from being drawn under the vehicle, the first drive device drives the sub-plate to drive the hollow main plate to flip downward synchronously, and at the same time the sub-plate extends out from the hollow main plate to form a stable interception barrier to prevent the struck pedestrian or object from being drawn under the vehicle, causing secondary damage to the pedestrian or vehicle body, thereby improving driving safety.

[0013] Furthermore, the first driving device includes a first connecting plate, a second connecting plate and a first cylinder, one end of the first connecting plate is rotatably connected to the end of the sub-plate away from the hollow main plate, the other end of the first connecting plate is hinged to one end of the second connecting plate, the other end of the second connecting plate is connected to the first cylinder, the second connecting plate is slidably installed on the bottom of the vehicle body along the extension and contraction direction of the first cylinder, and the first cylinder is installed on the bottom of the vehicle body and is controlled and connected to the controller.

[0014] According to the above technical means, the horizontal force transmitted by the first cylinder to the second connecting plate can be converted into a circular force by the movable connection between the sub-plate, the first connecting plate and the second connecting plate in sequence, thereby realizing the flexible rotation and positioning of the sub-plate relative to the hollow main plate; wherein the second connecting plate is slidably installed along the telescopic direction of the first cylinder, thereby ensuring the stability and accuracy of the first cylinder in driving the sub-plate to move, and can quickly and accurately adjust the position of the sub-plate during use to meet diverse usage requirements and enhance the overall functionality and flexibility.

[0015] Furthermore, the first driving device also includes a telescopic plate, which is located directly below the first cylinder. One end of the telescopic plate is installed on the bottom of the vehicle body, and the other end is connected to the end of the second connecting plate close to the first cylinder. The telescopic plate is configured to be able to extend or shorten with the sliding of the second connecting plate.

[0016] According to the above technical means, the first cylinder is shielded by the telescopic plate, and the telescopic plate can be synchronously extended and retracted with the sliding of the second connecting plate to prevent the first cylinder from being damaged by dust and impurities raised or other objects rolling under the vehicle during driving, thereby extending the service life of the first cylinder.

[0017] Furthermore, the telescopic plate is made of rubber material.

[0018] According to the above technical means, the rubber material has flexibility and elasticity, so that the telescopic plate can better absorb and disperse the impact energy during the process of extending or shortening as it slides with the second connecting plate, effectively reducing the collision and friction between mechanical components to further protect the first cylinder.

[0019] Furthermore, it also includes two isolation plates, and two installation cavities are formed at the bottom of the vehicle body, and the two installation cavities are respectively located in front of the two front wheels, and the two isolation plates are movably installed in the two installation cavities; second drive devices are respectively installed in the two installation cavities, and the two second drive devices are respectively connected to the two isolation plates, and the controller is also configured to control the second drive device to drive the isolation plate to extend out of the installation cavity according to the collision pressure signal detected by the collision detection device to prevent pedestrians from being caught under the front wheels.

[0020] According to the above-mentioned technical means, the isolation plate is driven by the second drive device to extend out of the installation cavity and be located directly in front of the front wheel to prevent the struck pedestrian from being rolled under the front wheel and crushed, causing secondary injury, further ensuring the life safety of pedestrians and improving the safety of the vehicle. Specifically, during a collision, when the collision detection device detects the collision pressure between the pedestrian and the vehicle body, the controller can respond quickly according to the collision pressure signal to control the second drive device to drive the isolation plate to extend out of the installation cavity and be located directly in front of the front wheel, forming a temporary safety barrier to block and prevent the struck pedestrian from being rolled under the front wheel, thereby greatly reducing the risk of injury to pedestrians in a collision accident.

[0021] Furthermore, the second driving device includes a spring, a guide rod and a locking structure. The guide rod is fixed in the installation cavity along the length direction of the isolation plate. The isolation plate is slidably installed on the guide rod through a mounting piece. The spring is sleeved on the guide rod, one end of which is fixed to the inner wall of the installation cavity, and the other end is fixed to the mounting piece; a locking structure is provided in the installation cavity, and the locking structure is connected to the isolation plate for unlocking or locking the isolation plate. The controller is controlled and connected to the locking structure.

[0022] According to the above technical means, efficient and reliable control of the isolation plate is achieved through the cooperation of the spring, guide rod and locking structure. When the isolation plate is retracted in the installation cavity, the locking structure locks the isolation plate, and the spring remains in a stretched or compressed state. During a collision, when the collision detection device detects the collision pressure between the pedestrian and the vehicle body, the controller can respond quickly according to the collision pressure signal to control the locking structure to unlock, so that the spring is reset and its elastic force is instantly released, pushing the isolation plate to extend smoothly and quickly along the guide rod to prevent the pedestrian from being caught under the wheel. Then, the locking structure remains locked after the isolation plate is extended, enhancing its stability; when the collision risk is eliminated, the controller controls the locking structure to unlock again, pushing the isolation plate to be smoothly retracted into the installation cavity, providing vehicle safety.

[0023] Furthermore, the locking structure includes a second cylinder, a locking plate, and a locking hole formed on the isolation plate. The second cylinder is installed in the installation cavity, the locking plate is connected to the second cylinder, and a protrusion that can cooperate with the locking hole is fixed on the locking plate. The second cylinder is controlled and connected to the controller.

[0024] According to the above-mentioned technical means, during a collision, when the collision detection device detects the collision pressure between the pedestrian and the vehicle body, the controller can respond quickly according to the collision pressure signal to control the second cylinder to drive the locking plate, so that the protrusion can be accurately inserted into or disengaged from the locking hole on the isolation plate, thereby achieving the locking or unlocking of the isolation plate, and improving the stability and efficiency of the unlocking and locking process.

[0025] Furthermore, the number of the locking holes is two or more, and the locking holes are evenly distributed along the length direction of the isolation plate.

[0026] According to the above technical means, multiple locking holes are evenly distributed along the length direction of the isolation plate, so that the isolation plate can adapt to vehicle models of different heights, with high flexibility and a wide range of applications.

[0027] Furthermore, it also includes a connecting thin plate, which is installed on the front end of the vehicle body through screws, and an inclined hole plate is fixed on the connecting thin plate.

[0028] According to the above technical means, by arranging an inclined perforated plate at the front end of the vehicle body, when a collision occurs, the inclined perforated plate will first contact the pedestrian to ensure that the pedestrian will not suffer greater injuries, and the protection effect is good.

[0029] Beneficial effects achieved by this utility model:

[0030] The utility model drives the interception plate to flip downward by the first drive device to realize the function of intercepting or blocking under the vehicle, preventing the pedestrian from being rolled under the vehicle, and enhancing driving safety. During the collision, when the collision detection device detects the collision pressure between the pedestrian and the vehicle body, the controller can respond quickly according to the collision pressure signal to control the first drive device to drive the interception plate to flip downward, that is, to flip from a state parallel to the vehicle body bottom plate to a state perpendicular to the vehicle body bottom plate, so as to realize the function of intercepting or blocking under the vehicle, thereby preventing the struck pedestrian from being rolled under the vehicle, avoiding or reducing secondary injuries, and after the blocking is completed, the controller controls the first drive device to drive the interception plate to flip upward to reset. During this process, the interception plate also has the tendency to push the struck pedestrian away from the bottom of the vehicle, which facilitates rescue, reduces the degree of injury to pedestrians in the accident, and protects the life safety of pedestrians and driving safety.

[0046] The technical solution of the present invention is described in detail below with reference to the accompanying drawings.

[0047] This embodiment relates to a vehicle with pedestrian protection function, such as Figure 1 and Figure 2 As shown, it includes a vehicle body 1, two front wheels 11 and two rear wheels 12 are symmetrically installed on the bottom of the vehicle body 1, and is characterized in that it also includes: a blocking component 2, the blocking component 2 includes an intercepting plate 21 and a first drive device 22, the intercepting plate 21 is rotatably installed on the bottom of the vehicle body 1 and is located in front of the two front wheels 11, the first drive device 22 is connected to the intercepting plate 21, and is used to drive the intercepting plate 21 to flip; a collision detection device 3, the collision detection device 3 is installed at the front end of the vehicle body 1, and is used to detect collision pressure; a controller, the controller is respectively connected to the first drive device 22 and the collision detection device 3, and the controller is configured to be able to control the first drive device 22 to drive the intercepting plate 21 to flip from a state parallel to the bottom of the vehicle body 1 to a state perpendicular to the bottom of the vehicle body 1 according to the collision pressure signal detected by the collision detection device 3, so as to prevent pedestrians from being caught under the vehicle.

[0048] In this embodiment, the interception plate 21 is flipped under the vehicle to achieve the function of interception or blocking, thereby preventing pedestrians from being caught under the vehicle and enhancing driving safety. Specifically, the collision detection device 3 can be a pressure sensor. In actual application, multiple pressure sensors can be installed at the front end of the vehicle body 1 to increase the number of collision occurrence points, and each pressure sensor is communicatively connected to the controller.

[0049] During a collision, when the collision detection device 3 detects the collision pressure between the pedestrian and the vehicle body 1, the controller can respond quickly according to the received collision pressure signal, and control the first drive device 22 to drive the interception plate 21 to flip downward, that is, flip from a state parallel to the vehicle body bottom plate to a state perpendicular to the vehicle body bottom plate, and can realize the function of intercepting or blocking under the vehicle, thereby preventing the hit pedestrian from being drawn under the vehicle, avoiding or reducing secondary injuries, and after the blocking is completed, the controller controls the first drive device 22 to drive the interception plate 21 to flip upward to reset. During this process, the interception plate 21 also has a tendency to push the hit pedestrian away from the bottom of the vehicle, which facilitates rescue, reduces the degree of injury to pedestrians caused by accidents, and protects the lives and driving safety of pedestrians. People in this field can understand that before resetting the interception plate 21, maintenance personnel can check each component if there is any damage, and can replace the corresponding components, and then perform the reset action.

[0050] In this embodiment, the intercepting plate 21 includes a hollow main plate 211 and a sub-plate 212. One end of the hollow main plate 211 is rotatably mounted on the bottom of the vehicle body 1, and the other end of the hollow main plate 211 is slidingly fitted with one end of the sub-plate 212. The other end of the sub-plate 212 is connected to the first driving device 22. The sub-plate 212 is configured so that when the hollow main plate 211 is parallel to the bottom of the vehicle body 1, the sub-plate 212 is retracted into the hollow main plate 211; when the hollow main plate 211 is perpendicular to the bottom of the vehicle body 1, the sub-plate 212 extends out of the hollow main plate 211.

[0051] like Figure 3 and Figure 4As shown, in this embodiment, the interception plate 2 is composed of a hollow main plate 211 and a sub-plate 212 that are slidably fitted together, so that the interception plate 2 can be freely extended and retracted when flipped to adapt to vehicles of different heights, with high flexibility. Specifically, during installation, one end of the hollow main plate 211 is installed on the bottom of the vehicle body 1 through the first rotating shaft, and the other end is slidably fitted with the sub-plate 212; when the vehicle is in a normal driving state, the hollow main plate 211 remains parallel to the bottom of the vehicle body 1, and the sub-plate 212 is retracted inside the hollow main plate 211, which reduces The air resistance is reduced while maintaining the overall aesthetics of the vehicle body; when an emergency situation requires to intercept or prevent a pedestrian or object from being hit and being rolled under the vehicle, the first drive device 22 drives the sub-plate 212 to drive the hollow main plate 211 to synchronously flip downward with the first rotating shaft as the center of the circle. At the same time, the sub-plate 212 can extend out from the hollow main plate 211 to realize the flipping action of the interception plate 21 and form a stable interception barrier at the bottom of the vehicle body 1, preventing the pedestrian or object from being hit and being rolled under the vehicle, causing secondary damage to the pedestrian or the vehicle body, and improving driving safety.

[0052] In this embodiment, the first driving device 22 includes a first connecting plate 221, a second connecting plate 222 and a first cylinder 223. One end of the first connecting plate 221 is rotatably connected to the end of the sub-plate 212 away from the hollow main plate 211. The other end of the first connecting plate 221 is hinged to one end of the second connecting plate 222. The other end of the second connecting plate 222 is connected to the first cylinder 223. The second connecting plate 222 is slidably installed at the bottom of the vehicle body 1 along the extension and contraction direction of the first cylinder 223. The first cylinder 223 is installed at the bottom of the vehicle body 1 and is controlled and connected to the controller.

[0053] like Figure 3 and Figure 4As shown, in this embodiment, the sub-plate 212, the first connecting plate 221 and the second connecting plate 222 are movably connected in sequence, so that the horizontal force can be converted into a circumferential force, so that the sub-plate 212 drives the hollow main plate 211 to rotate and position flexibly. Specifically, during installation, the end of the sub-plate 212 away from the hollow main plate 211 is rotatably connected to one end of the first connecting plate 221 through the second rotating shaft. When it is necessary to intercept or prevent the hit pedestrian or object from being rolled under the vehicle, the first cylinder 223 drives the second connecting plate 222 to slide linearly in the direction away from the intercepting plate 21, thereby driving the first connecting plate 221 to pull the sub-plate 212. Under the action of the hinge between the first rotating shaft, the second rotating shaft and the first connecting plate 221 and the second connecting plate 222, the sub-plate 212 drives the hollow main plate 211 to rotate with the first rotating shaft as the center, so that the hollow main plate 211 and the sub-plate 212 flip downward, and at the same time, the sub-plate 212 extends out of the hollow main plate 211 to form an interception barrier under the vehicle to prevent the hit pedestrians or objects from being rolled under the vehicle, causing secondary damage to the pedestrians or the vehicle body. After the blocking is completed, the first cylinder 223 drives the second connecting plate 222 to slide in a straight line in the direction close to the interception plate 21, thereby transmitting the first connecting plate 221 to push the sub-plate 212 to drive the hollow main plate 211 to flip upward for reset. It can be understood that the rotation angle of the hinge of the first connecting plate 221 and the second connecting plate 222 is less than 90 degrees and a compression spring can be installed at the hinge position for better reset, or the reset can be completed with manual assistance.

[0054] In this embodiment, the first driving device 22 further includes a telescopic plate 224, which is located directly below the first cylinder 223. One end of the telescopic plate 224 is mounted on the bottom of the vehicle body 1, and the other end is connected to an end of the second connecting plate 222 close to the first cylinder 223. The telescopic plate 224 is configured to extend or shorten as the second connecting plate 222 slides. Figure 2 and Figure 3 As shown, a telescopic plate 224 is provided directly below the first cylinder 223 and can be extended and retracted following the sliding of the second connecting plate 222. This can protect the first cylinder 223 to prevent the first cylinder 223 from being damaged by dust and impurities raised or other objects rolling under the vehicle during driving, thereby extending the service life of the first cylinder 223. As a preferred embodiment, the telescopic plate 224 is made of rubber.

[0055] In this embodiment, two isolation plates 4 are also included. Two installation cavities 13 are formed at the bottom of the vehicle body 1. The two installation cavities 13 are respectively located directly in front of the two front wheels 11. The two isolation plates 4 are respectively movably installed in the two installation cavities 13; second drive devices 5 are respectively installed in the two installation cavities 13, and the two second drive devices 5 are respectively connected to the two isolation plates 4. The controller is also configured to control the second drive device 5 to drive the isolation plate 4 to extend out of the installation cavity 13 according to the collision pressure signal detected by the collision detection device 3 to prevent pedestrians from being caught under the front wheels 11.

[0056] like Figure 5 and Figure 7 As shown, the isolation plate 4 of this embodiment extends out of the mounting cavity 13, which can prevent the struck pedestrian from being rolled under the front wheel 11 to prevent being crushed and causing secondary injury, further ensuring the life safety of the pedestrian. Specifically, when the vehicle is in normal driving state, the isolation plate 4 is hidden in the mounting cavity 13, which not only reduces air resistance but also maintains the overall aesthetics of the vehicle body. During a collision, when the collision detection device 3 detects the collision pressure between the pedestrian and the vehicle body 1, the controller can respond quickly according to the received collision pressure signal, controlling the first drive device 22 to drive the interception plate 21 to flip downward, while also controlling the second drive device 5 to drive the isolation plate 4 out of the mounting cavity 13, located directly in front of the front wheel 11, forming a temporary safety barrier to block and prevent the struck pedestrian from being rolled under the front wheel 11, further reducing the risk of injury to pedestrians in a collision accident.

[0057] In this embodiment, the second driving device 5 includes a spring 51, a guide rod 52 and a locking structure 53. The guide rod 52 is fixed in the mounting cavity 13 along the length direction of the isolation plate 4. The isolation plate 4 is slidably installed on the guide rod 52 through the mounting member 41. The spring 51 is sleeved on the guide rod 52, one end of which is fixed to the inner wall of the mounting cavity 13, and the other end is fixed to the mounting member 41; a locking structure 53 is provided in the mounting cavity 13, and the locking structure 53 is connected to the isolation plate 4 for unlocking or locking the isolation plate 4. The controller is controlled and connected to the locking structure 53.

[0058] like Figure 5As shown, in the actual process of this embodiment, when the isolation plate 4 is retracted in the installation cavity 13, the locking structure 53 locks the isolation plate 4, and the spring 51 remains in a stretched or compressed state. During the collision, when the collision detection device 3 detects the collision pressure between the pedestrian and the vehicle body 1, the controller can respond quickly according to the collision pressure signal to control the locking structure 53 to unlock, so that the spring 51 is reset and its elastic force is instantly released, pushing the isolation plate 4 out of the installation cavity 13 smoothly and quickly along the guide rod 52, preventing the pedestrian from being drawn into the bottom of the front wheel 11, and then, the locking structure 53 locks the isolation plate 4 again after the isolation plate 4 is extended, thereby enhancing its stability; when the collision risk is eliminated, after the maintenance personnel can inspect it, the controller controls the locking structure 53 to unlock again, and the isolation plate 4 can be pushed back into the installation cavity 13 smoothly with manual assistance, so that the spring 51 is kept in a stretched or compressed state again, and then the locking structure 53 re-locks the isolation plate 4.

[0059] In this embodiment, the locking structure 53 includes a second cylinder 531, a locking plate 532 and a locking hole 533 formed on the isolation plate 4. The second cylinder 531 is installed in the installation cavity 13, the locking plate 532 is connected to the second cylinder 531, and a protrusion 5321 that can cooperate with the locking hole 533 is fixed on the locking plate 532. The second cylinder 531 is controlled and connected to the controller.

[0060] like Figure 6 As shown, during installation, the guide plate 534 can be fixed in the installation cavity, and the locking plate 532 is slidably installed on the guide plate 534 to stabilize the guidance. During a collision, when the collision detection device 3 detects the collision pressure between the pedestrian and the vehicle body 1, the controller can respond quickly according to the collision pressure signal to control the second cylinder 531 to drive the locking plate 532 to slide on the guide plate 534, so that the protrusion 5321 can be accurately inserted into or disengaged from the locking hole 533 on the isolation plate 4, thereby locking or unlocking the isolation plate, thereby improving the stability and efficiency of the unlocking and locking process; as a preferred embodiment, the number of locking holes 533 is two or more, and each locking hole 533 is evenly distributed along the length direction of the isolation plate 4, with high flexibility and a wide range of applications.

[0061] In this embodiment, a connecting plate 6 is further included, which is mounted on the front end of the vehicle body 1 by screws 7, and an inclined hole plate 8 is fixed on the connecting plate 6; Figure 1 and Figure 2 As shown, in actual application of this embodiment, the inclined hole plate 8 can be made of honeycomb aluminum. The inclined hole plate 8 is installed at the front end of the vehicle body 1 through the connecting thin plate 6 and the screw 7. When a collision occurs, the inclined hole plate 8 first contacts the pedestrian and collapses to absorb energy to ensure that the pedestrian will not suffer greater injuries. After the collision, the inclined hole plate 8 can be disassembled and replaced by the screw 7, which is convenient and quick.
