Description
Technical Field
[0001] This application relates to the field of vehicle technology, and more particularly to a vehicle anti-collision beam and a vehicle. Background Technology
[0002] The front of the vehicle is equipped with a crash beam, which has a much higher structural rigidity than the front of the vehicle. When a collision occurs, the crash beam protects the vehicle and the passengers inside.
[0003] In the existing technology, when a vehicle is moving forward and a collision between a pedestrian or two-wheeled vehicle is inevitable, the pedestrian or two-wheeled vehicle rider will first hit the vehicle's anti-collision beam. Due to the high structural rigidity of the anti-collision beam, the pedestrian or two-wheeled vehicle rider suffers higher collision injuries, resulting in poor protection for the pedestrian or two-wheeled vehicle rider. Summary of the Invention
[0004] This application provides a vehicle anti-collision beam and a vehicle to solve the technical problem that existing anti-collision beams result in higher collision injuries to pedestrians or two-wheeled vehicle riders.
[0005] A first aspect of this application provides a vehicle anti-collision beam, comprising:
[0006] Beam structure;
[0007] At least one beam mounting mechanism includes a mounting base, a connector, and a drive assembly. The mounting base is configured to be disposed at the front end of a vehicle. The connector is movably connected to the mounting base and detachably connected to the beam. The drive assembly is drivenly connected to the connector.
[0008] The drive assembly is configured to drive the connector to move from a first position to a second position on the mounting base, thereby disconnecting the connector from the beam and causing the beam to detach from the mounting base.
[0009] In one possible implementation, the beam is provided with at least one receiving cavity and at least one mounting port, each mounting port is connected to the receiving cavity in a corresponding manner, the mounting base is provided with a sliding groove, the connecting member is a sealing plug, one end of the sealing plug is disposed in the mounting port, and the periphery of the sealing plug abuts against the periphery of the mounting port to seal the mounting port;
[0010] The other end of the sealing plug is slidably connected to the slide groove, and the driving component is a gas generator, the output end of which is connected to the accommodating cavity.
[0011] The gas generating device is configured to deliver gas into the accommodating cavity to push the sealing plug on the slide in a direction away from the accommodating cavity, thereby disengaging the sealing plug from the mounting port and disconnecting the sealing plug from the beam.
[0012] In one possible implementation, the system also includes an onboard radar and a controller, wherein the onboard radar and the gas generator are electrically connected to the controller, respectively.
[0013] Both the vehicle-mounted radar and the controller are installed on the vehicle, and the vehicle-mounted radar is used to collect data information of the area in front of the vehicle.
[0014] The controller is configured to determine the distance and speed between the vehicle and a pedestrian or two-wheeled vehicle in the area in front of the vehicle based on the data information, and to control the gas generator to deliver the gas into the accommodating cavity when the distance is less than a first preset value and the speed is greater than a second preset value.
[0015] In one possible implementation, the gas generating device includes a gas generator and an igniter, the gas generator being connected to the igniter and the igniter being electrically connected to the controller;
[0016] The controller is configured to, when the distance is less than a first preset value and the speed is greater than a second preset value, control the igniter to ignite the gas-generating agent in the gas generator so that the gas generator produces the gas.
[0017] In one possible implementation, the number of beam mounting mechanisms is two, and the two beam mounting mechanisms are symmetrical about the center of the beam.
[0018] In one possible implementation, there are two accommodating cavities, and the two accommodating cavities are located at opposite ends of the beam.
[0019] In one possible implementation, the mounting base includes a support column, a mounting plate, and a mounting housing;
[0020] One side of the mounting plate is disposed at one end of the support column, and the other side of the mounting plate is used to be disposed on the vehicle body. The mounting housing is disposed at the other end of the support column. The end of the mounting housing facing the beam is provided with a first opening, and the end of the mounting housing away from the beam is provided with a second opening. The end of the sealing plug away from the accommodating cavity is disposed in the inner cavity of the mounting housing through the first opening. The inner cavity of the mounting housing forms the sliding groove.
[0021] In one possible implementation, the length of the groove extending in the direction of extension is greater than the length of the sealing plug.
[0022] In one possible implementation, the drive assembly is positioned on the side of the beam facing the vehicle.
[0023] A second aspect of this application provides a vehicle, including:
[0024] Vehicle body;
[0025] It also includes the vehicle anti-collision beam described in any of the above-mentioned items, wherein the vehicle anti-collision beam is disposed on the vehicle body.
[0026] This application provides a vehicle anti-collision beam and a vehicle. When it is observed that a pedestrian or cyclist is about to collide with the vehicle, the anti-collision beam drives the connecting member to move from a first position to a second position on the mounting base via a drive assembly. This causes the connecting member to disconnect from the beam, allowing the beam to detach from the mounting base and thus detach from the vehicle. Consequently, the pedestrian or cyclist will not collide with the beam and will instead collide with the front of the vehicle. Since the front of the vehicle has lower structural stiffness than the beam, the overall stiffness of the front of the vehicle is reduced during the collision. Therefore, compared to the pedestrian or cyclist directly colliding with the beam, the injury suffered by the pedestrian or cyclist colliding with the front of the vehicle is relatively smaller. This provides protection for the pedestrian or cyclist and reduces the collision injury suffered by the pedestrian or cyclist. Attached Figure Description

[0049] The front of the vehicle is equipped with a crash beam, which has a much higher structural rigidity than the front of the vehicle. When a collision occurs, the crash beam protects the vehicle and the passengers inside.
[0050] When two objects with greater stiffness collide, the collision time is shorter, the force is greater, and the acceleration is also greater, while when two objects with less stiffness collide, the collision time is longer, the force is smaller, and the acceleration is also smaller.
[0051] Acceleration is an indicator of the severity of personal injury; the lower the acceleration experienced by the human body, the less damage will occur. Reducing the stiffness of the front of a vehicle during a collision can effectively protect pedestrians and two-wheeled vehicle riders.
[0052] In existing technologies, the structural rigidity of the anti-collision beam is usually increased to ensure the safety of passengers inside the vehicle. When the vehicle is moving forward, a collision between the vehicle and a pedestrian or two-wheeled vehicle is inevitable. Among the two-wheeled vehicles, such as bicycles, electric vehicles, motorcycles, etc., the pedestrian or two-wheeled vehicle rider will hit the vehicle's anti-collision beam first. Due to the high structural rigidity of the anti-collision beam, the collision injury suffered by the pedestrian or two-wheeled vehicle rider is high. That is, the existing anti-collision beam has a poor protective effect on pedestrians or two-wheeled vehicle riders.
[0053] To address the technical problem that existing anti-collision beams result in high collision injuries to pedestrians or two-wheeled vehicle riders, this application proposes a vehicle anti-collision beam and a vehicle. The vehicle anti-collision beam includes a beam body and at least one beam body mounting mechanism. The beam body mounting mechanism includes a mounting seat, a connector, and a drive assembly. The mounting seat is positioned at the front end of the vehicle. The connector is movably connected to the mounting seat and detachably connected to the beam body. The drive assembly is driven to connect to the connector. The drive assembly is configured to drive the connector from a first position on the mounting seat to a second position, thereby disconnecting the connector from the beam body and causing the beam body to detach from the mounting seat.
[0054] In the vehicle anti-collision beam of this application embodiment, when it is observed that a pedestrian or a cyclist is about to collide with the vehicle, the drive assembly is activated. The drive assembly moves the drive connector from a first position on the mounting seat to a second position, thereby disconnecting the connector from the beam and causing the beam to detach from the mounting seat, i.e., detaching the beam from the vehicle. As a result, the pedestrian or cyclist will not collide with the beam, but will instead collide with the front of the vehicle. Since the front of the vehicle has lower structural stiffness than the beam, the overall stiffness of the front of the vehicle is reduced during the collision. Therefore, compared to the pedestrian or cyclist directly colliding with the beam, the injury suffered by the pedestrian or cyclist who collides with the front of the vehicle is relatively smaller, thus protecting the pedestrian or cyclist and reducing the collision injury suffered by the pedestrian or cyclist.
[0055] The technical solution of the application will be described in detail below with reference to the accompanying drawings and specific embodiments. These specific embodiments can be combined with each other, and the same or similar concepts or processes may not be described again in some embodiments.
[0056] Reference Figures 1 to 6 As shown, Figure 1 A schematic diagram of the structure of a vehicle anti-collision beam provided for an embodiment of this application; Figure 2 for Figure 1 A structural diagram from another angle; Figure 3 A partial cross-sectional structural diagram of a vehicle anti-collision beam provided for an embodiment of this application; Figure 4 for Figure 2A structural diagram from another angle; Figure 5 A schematic diagram of the vehicle structure provided for an embodiment of this application; Figure 6 A structural block diagram showing the connection between the vehicle-mounted radar and drive components and the controller in a vehicle anti-collision beam provided for embodiments of this application.
[0057] In the embodiments of this application, reference is made to Figures 1 to 3 As shown, an embodiment of this application provides a vehicle anti-collision beam, including a beam body 100 and at least one beam body mounting mechanism 200.
[0058] The beam mounting mechanism 200 includes a mounting base 300, a connector 400, and a drive assembly 500. The mounting base 300 is used to be set at the front end of the vehicle. The connector 400 is movably connected to the mounting base 300 and is detachably connected to the beam 100. The drive assembly 500 is drivenly connected to the connector 400.
[0059] The drive assembly 500 is configured to move the drive connector 400 from a first position to a second position on the mounting base 300, thereby disengaging the connector 400 from the beam 100 and causing the beam 100 to detach from the mounting base 300.
[0060] In the vehicle anti-collision beam of this application embodiment, the beam 100 can be the anti-collision crossbeam of the vehicle. The beam 100 can be selected with high structural strength and rigidity to improve the anti-collision effect of the vehicle.
[0061] The beam mounting mechanism 200 includes a mounting base 300, a connector 400, and a drive assembly 500. The mounting base 300 is located at the front end of the vehicle and can be either detachably or fixedly connected to the front end of the vehicle. The connector 400 is movably connected to the mounting base 300, meaning that the connector 400 can move relative to the mounting base 300 and can move to a first position or a second position on the mounting base 300. The connector 400 is detachably connected to the beam 100. For example, the connector 400 can be a rotating latch. When the rotating latch is in the first position on the mounting base 300, the rotating latch will be connected to the beam 100. When the rotating latch is in the second position on the mounting base 300, the rotating latch will be disconnected from the beam 100.
[0062] The drive assembly 500 is driven to connect with the connector 400. The drive assembly 500 is configured to drive the connector 400 from a first position on the mounting base 300 to a second position, so that the connector 400 is disconnected from the beam 100, so that the beam 100 is detached from the mounting base 300, that is, the beam 100 is detached from the front end of the vehicle.
[0063] The drive assembly 500 can be started automatically or manually by the driver. Automatic drive can be detected by radar. When a collision is detected, the drive assembly 500 can be started by the controller 700. Alternatively, when the driver determines that a collision is about to occur, the driver of the vehicle can manually start the drive assembly 500.
[0064] For example, when the connector 400 is a rotating buckle, the drive assembly 500 can be a drive motor, which drives the connector 400 to move from the first position to the second position on the mounting base 300.
[0065] In the vehicle anti-collision beam of this application embodiment, when it is observed that a pedestrian or a cyclist is about to collide with the vehicle, the drive assembly 500 is activated. The drive assembly 500 causes the drive connector 400 to move from a first position to a second position on the mounting base 300, thereby disconnecting the connector 400 from the beam 100 and causing the beam 100 to detach from the mounting base 300. That is, the beam 100 detaches from the front of the vehicle, so that the pedestrian or cyclist will not collide with the beam 100. Instead, the pedestrian or cyclist will collide with the front of the vehicle. Since the front of the vehicle has lower structural stiffness than the beam 100, the overall stiffness of the front of the vehicle is reduced during the collision. Therefore, compared to the pedestrian or cyclist directly colliding with the beam 100, the injury suffered by the pedestrian or cyclist who collides with the front of the vehicle is relatively smaller, thus protecting the pedestrian or cyclist and reducing the collision injury suffered by the pedestrian or cyclist.
[0066] It should be noted that when a collision between the vehicle and a medium or large vehicle is unavoidable, the drive component 500 is not activated. In this case, the beam 100 can protect the front end of the vehicle, improve the front rigidity of the vehicle, and enhance the safety of the passengers inside the vehicle.
[0067] In other embodiments, the beam 100 is provided with at least one accommodating cavity 110 and at least one mounting port 111, each mounting port 111 being connected to the accommodating cavity 110 in a corresponding manner. The mounting base 300 is provided with a sliding groove 800. The connector 400 is a sealing plug, one end of which is disposed in the mounting port 111, and the periphery of the sealing plug abuts against the periphery of the mounting port 111 to seal the mounting port 111.
[0068] The other end of the sealing plug is slidably connected to the slide groove 800. The drive assembly 500 is a gas generator, and the output end of the gas generator is connected to the accommodating cavity 110.
[0069] The gas generator is configured to supply gas into the accommodating cavity 110 to push the sealing plug on the slide 800 in a direction away from the accommodating cavity 110, so that the sealing plug is disengaged from the mounting port 111 and the sealing plug is disconnected from the beam 100.
[0070] In this embodiment, when it is observed that a pedestrian or a cyclist is about to collide with the vehicle, the gas generator is activated, which delivers gas into the accommodating cavity 110. The gas will push the sealing plug on the slide 800 in a direction away from the accommodating cavity 110. When the gas in the accommodating cavity 110 reaches a certain amount, the sealing plug will disengage from the mounting port 111, that is, the sealing plug will detach from the accommodating cavity 110, thereby disconnecting the sealing plug from the beam 100, thus realizing the detachment of the beam 100 from the front end of the vehicle.
[0071] The sealing plug can be a piston.
[0072] It should be noted that the gas generator can be started automatically or manually. Automatic start can be achieved through radar detection. When a collision is detected, the gas generator can be started by the controller 700. Alternatively, when the driver determines that a collision is about to occur, the driver can manually start the gas generator.
[0073] In one embodiment, the vehicle-mounted radar 600 and the controller 700 are also included, with the vehicle-mounted radar 600 and the gas generator electrically connected to the controller 700 respectively.
[0074] Both the vehicle radar 600 and the controller 700 are installed on the vehicle. The vehicle radar 600 is used to collect data information of the area in front of the vehicle.
[0075] The controller 700 is configured to determine the distance and speed between a pedestrian or two-wheeled vehicle and the vehicle in the area in front of the vehicle based on data information, and to control the gas generator to deliver gas into the accommodating cavity 110 when the distance is less than a first preset value and the speed is greater than a second preset value.
[0076] In this embodiment, during vehicle operation, the vehicle-mounted radar 600 collects data information of the area in front of the vehicle in real time, such as three-dimensional point cloud data and reflection intensity data. The vehicle-mounted radar 600 converts the data information into electrical signals and transmits them to the controller 700. The controller 700 processes the electrical signals to obtain the distance and speed between the vehicle and pedestrians or two-wheeled vehicles in the area in front of the vehicle.
[0077] It should be noted that the vehicle-mounted radar 600 can be a lidar.
[0078] Specifically, the controller 700 can be an Electronic Control Unit (ECU). Based on the electrical signal input from the vehicle radar 600, the controller 700 outputs characteristic quantities: amplitude parameter K1, representing the distance between the vehicle and a pedestrian or two-wheeled vehicle; and speed parameter K2, representing the relative speed between the vehicle and the pedestrian or two-wheeled vehicle, after differentiation. When K1 is less than a first preset value and K2 is greater than a second preset value, the vehicle's ECU controls the gas generator to deliver gas into the accommodating cavity 110, causing the sealing plug to disconnect from the beam 100, thus allowing the beam 100 to detach from the front end of the vehicle.
[0079] The following describes the signal processing flow of the electronic control unit for the vehicle radar 600 in the embodiments of this application.
[0080] S101, the A / D conversion module of the electronic control unit performs analog-to-digital conversion on the output voltage signal Uo of the vehicle radar 600. After conversion, the Uo signal is changed from an analog signal to a digital signal, which facilitates subsequent digital processing and calculation.
[0081] S102. Filter the digital signal after A / D conversion to effectively eliminate noise interference.
[0082] S103. Read and output the amplitude of Uo in real time, and store it as K1.
[0083] S104. The main processor MCU calculates the derivative dUo / dt and outputs the real-time derivative result, which is stored as K2.
[0084] After signal processing by the vehicle radar 600 of the electronic control unit, a digital signal is obtained, and the characteristic parameters K1 and K2 of the signal are extracted. Whether the signal characteristic parameters exceed the first preset value or the second preset value is the basis for determining whether the electronic control unit should start the gas generator.
[0085] After the vehicle radar 600 signal is processed through the above S101 to S104 process, characteristic parameters K1 and K2 are obtained. The following describes the working process of the electronic control unit.
[0086] S201: The electronic control unit compares and judges the signal characteristic parameters K1 and K2 of the vehicle radar 600. If K1 is less than the first preset value and K2 is greater than the second preset value, proceed to step S202. If K1 is not less than the first preset value and K2 is not greater than the second preset value at the same time, continue to steps S101 to S104 in real time. It should be noted here that the first and second preset values are obtained from the vehicle collision calibration test.
[0087] S202, the electronic control unit starts the gas generator.
[0088] It should be noted here that the electronic control unit activates the gas generator, which produces gas that pushes the sealing plug to move, causing the beam 100 to detach from the front of the vehicle, thereby reducing the stiffness of the front of the vehicle.
[0089] It should be noted that in some embodiments, the vehicle radar 600 can also directly acquire the distance and speed between the vehicle and pedestrians or two-wheeled vehicles in the area in front of the vehicle. Then, the controller 700 determines that when the distance is less than a first preset value and the speed is greater than a second preset value, it controls the gas generator to deliver gas into the accommodating cavity 110.
[0090] In some embodiments, the gas generating device includes a gas generator 510 and an igniter 520, the gas generator 510 being connected to the igniter 520 and the igniter 520 being electrically connected to a controller 700; the controller 700 is configured to control the igniter 520 to ignite the gas-generating agent in the gas generator 510 when the distance is less than a first preset value and the speed is greater than a second preset value, so that the gas generator 510 generates gas.
[0091] In this embodiment, when the distance is less than the first preset value and the speed is greater than the second preset value, the controller 700 controls the igniter 520 to ignite the gas-generating agent in the gas generator 510, so that the gas generator 510 instantly generates high-pressure gas, instantly pushing the sealing plug to move, thereby causing the beam 100 to detach from the front of the vehicle, thereby reducing the rigidity of the front of the vehicle and reducing collision damage to pedestrians and two-wheeled vehicle riders.
[0092] Among them, the gas-generating agents can be ammonium nitrate (NH4NO3) or nitroguanidine (CNH4NO3). 22 NNO2 and azole compounds such as 5-aminotetrazole mainly produce nitrogen gas, thus avoiding the release of large amounts of toxic gases and ensuring the safety of pedestrians and two-wheeled vehicle riders.
[0093] In other embodiments, there are two beam mounting mechanisms 200, and the two beam mounting mechanisms 200 are symmetrical about the beam 100.
[0094] The more beam mounting mechanisms 200 there are, the more stably the beam 100 is fixed. In this embodiment, there are two beam mounting mechanisms 200, and the two beam mounting mechanisms 200 are symmetrical about the center of the beam 100, so that the beam 100 is evenly distributed and the beam 100 can be stably fixed to the front end of the vehicle.
[0095] In some possible embodiments, there are two accommodating cavities 110, and the two accommodating cavities 110 are located at opposite ends of the beam 100.
[0096] In this embodiment, both ends of the beam 100 are provided with accommodating cavities 110. The accommodating cavities 110 at both ends of the beam 100 are respectively connected to the sliding grooves 800 of the two mounting seats 300 by two sealing plugs, which ensures the stability of the beam 100 connection and the uniformity of the force.
[0097] In one possible embodiment, the mounting base 300 includes a support column 310, a mounting plate 320, and a mounting housing 330; one side of the mounting plate 320 is disposed at one end of the support column 310, and the other side of the mounting plate 320 is used to be mounted on the vehicle body; the mounting housing 330 is disposed at the other end of the support column 310; the end of the mounting housing 330 facing the beam 100 is provided with a first opening 331, and the end of the mounting housing 330 away from the beam 100 is provided with a second opening 332; the end of the sealing plug away from the accommodating cavity 110 is disposed in the inner cavity of the mounting housing 330 through the first opening 331; and the inner cavity of the mounting housing 330 forms a groove 800.
[0098] In this embodiment, the supporting column 310 creates a buffer gap between the beam 100 and the vehicle, thus providing buffer protection for the vehicle.
[0099] The inner cavity of the mounting housing 330 forms a groove 800. When the gas generator is started, the gas generator delivers gas into the accommodating cavity 110. The gas pushes the sealing plug in the inner cavity of the mounting housing 330 and moves it in a direction away from the accommodating cavity 110, so that the sealing plug is disengaged from the mounting port 111 and enters the depth of the inner cavity of the mounting housing 330, so that the sealing plug is disconnected from the beam 100.
[0100] In another possible embodiment, the length of the groove 800 in the extending direction is greater than the length of the sealing plug.
[0101] In this embodiment, the sealing plug can be completely located within the slide groove 800, ensuring that the sealing plug can be completely detached from the receiving cavity 110.
[0102] In one embodiment, the drive assembly 500 is disposed on the side of the beam 100 facing the vehicle.
[0103] In this embodiment, the drive assembly 500 is positioned on the side of the beam 100 facing the vehicle to prevent collisions that could cause the drive assembly 500 to malfunction and prevent the beam 100 from detaching.
[0104] A second aspect of this application provides a vehicle, including a vehicle body and a vehicle anti-collision beam according to any of the above embodiments.
[0105] Vehicle anti-collision beams are installed on the vehicle body.
[0106] In the vehicle of this application embodiment, a vehicle anti-collision beam is provided on the vehicle body. The vehicle anti-collision beam includes a beam body 100 and at least one beam body mounting mechanism 200. The beam body mounting mechanism 200 includes a mounting base 300, a connector 400, and a drive assembly 500. The mounting base 300 is used to be disposed at the front end of the vehicle. The connector 400 is movably connected to the mounting base 300 and is detachably connected to the beam body 100. The drive assembly 500 is drivenly connected to the connector 400. The drive assembly 500 is configured to drive the connector 400 to move from a first position to a second position on the mounting base 300, so that the connector 400 is disconnected from the beam body 100, so that the beam body 100 is detached from the mounting base 300.
[0107] In the vehicle of this application embodiment, when it is observed that a pedestrian or a two-wheeled vehicle rider is about to collide with the vehicle, the drive assembly 500 is activated. The drive assembly 500 causes the drive connector 400 to move from a first position on the mounting base 300 to a second position, thereby disconnecting the connector 400 from the beam 100 and causing the beam 100 to detach from the mounting base 300. In other words, the beam 100 is detached from the vehicle, so the pedestrian or two-wheeled vehicle rider will not collide with the beam 100. Instead, the pedestrian or two-wheeled vehicle rider will collide with the front of the vehicle. Since the front of the vehicle has lower structural stiffness than the beam 100, the overall stiffness of the front of the vehicle is reduced during the collision. Therefore, compared to the pedestrian or two-wheeled vehicle rider directly colliding with the beam 100, the injury suffered by the pedestrian or two-wheeled vehicle rider when colliding with the front of the vehicle is relatively smaller, thus protecting the pedestrian or two-wheeled vehicle rider and reducing the collision injury suffered by the pedestrian or two-wheeled vehicle rider.
[0108] It should be noted that the vehicle anti-collision beam of this application can be installed at any position around the vehicle, such as the front, rear, left, or right side of the vehicle. The vehicle anti-collision beam of this application can be placed in any place where a collision is likely to occur.
