Description

Technical Field

[0001] The present invention relates to the technical field of vehicles, and in particular to a force transmission component, a shock absorbing tower seat device, a vehicle and a vehicle control method. Background Art

[0002] In vehicle collision accidents, 25% offset collision is a relatively common collision form. In the related art, when a vehicle has a 25% offset collision, the front cabin and chassis structure are usually relied on to withstand the impact force or change the direction of the impact force to mitigate the impact suffered by the vehicle. However, this method will damage the front end of the vehicle body and the vehicle body structure at the driver's cabin when the impact force is large, which can easily threaten the safety of the driver and passengers. Summary of the invention

[0003] The present application provides a force transmission assembly, a shock tower device, a vehicle and a vehicle control method to at least solve the technical problem that a vehicle collision easily poses a threat to the safety of the driver and passengers. The technical solution adopted by the present invention is as follows:

[0004] According to a first aspect of the present application, a force transmission assembly is provided for a vehicle, the force transmission assembly comprising a shell, an ejection assembly and a driver, the shell being used to be fixed on the vehicle; the ejection assembly is connected to the shell and can move relative to the shell; the driver is connected to the shell, and when the vehicle is hit by an obstacle, the driver can drive the ejection assembly to move from a first position to a second position; when the ejection assembly is in the second position, the ejection assembly contacts the obstacle and is subjected to a reverse thrust from the obstacle, so that the ejection assembly pushes the vehicle away from the obstacle under the action of the reverse thrust.

[0005] According to the above technical means, when the vehicle is hit by an obstacle, the ejection assembly can be driven by the driver to move from the first position to the second position. When the ejection assembly moves to the second position, the ejection assembly contacts the obstacle and squeezes the obstacle, so that the obstacle can generate a reaction force on the ejection assembly, that is, a reverse thrust. At the same time, since the driver has a driving force on the ejection assembly, the ejection assembly will generate a thrust on the driver and the shell under the action of the reverse thrust, thereby generating a thrust on the vehicle to push the vehicle to move in the direction away from the obstacle, thereby separating the vehicle from the obstacle, avoiding the vehicle from being continuously hit by the obstacle, avoiding damage to the structure of the vehicle's cabin, and ensuring the safety of the passengers in the cabin.

[0006] In a possible embodiment, the ejection assembly includes a sliding member and a pushing member, the sliding member is slidably connected to the shell, and the driver can drive the sliding member to slide so that the ejection assembly moves relative to the shell; the pushing member is connected to the sliding member, and when the ejection assembly is in the second position, the pushing member contacts the obstacle and is subjected to the reverse thrust of the obstacle.

[0007] According to the above technical means, the ejection assembly includes a sliding member and a pushing member, so that the structure of the ejection assembly can be relatively simple, thereby facilitating the assembly and setting of the ejection assembly.

[0008] In a possible embodiment, the pushing member includes a guide rod and a push block, one end of the guide rod is connected to the sliding member; the other end of the guide rod is connected to the push block, and when the ejection assembly is in the second position, the push block contacts the obstacle and is subjected to the reverse thrust of the obstacle.

[0009] According to the above technical means, through the setting of the guide rod and the push block, when the vehicle collides with an obstacle, the push block can contact the obstacle more quickly, and then the vehicle can be pushed away from the obstacle more quickly to reduce the damage to the vehicle.

[0010] In a possible implementation, the shell is provided with a receiving cavity and a through hole communicating with the receiving cavity; the sliding member is located in the receiving cavity and can slide in the receiving cavity; the guide rod passes through the through hole; and the push block is located outside the receiving cavity.

[0011] According to the above technical means, in the process of the sliding member pushing the push block to move to the second position through the guide rod, the guide rod can slide in the through hole to guide the push block through the cooperation between the guide rod and the through hole to avoid the push block shaking or deflecting and affecting the effect of pushing the vehicle sideways.

[0012] In a possible implementation, there are multiple guide rods, which are spaced apart along a first direction, and the first direction is perpendicular to the sliding direction of the sliding member; there are multiple through holes, and one guide rod is passed through one through hole.

[0015] According to the above technical means, as long as the electromagnetic drive component is continuously energized, it can ensure that the electromagnetic drive component continues to generate force toward the obstacle on the magnetic component, thereby increasing the contact time between the push block and the obstacle, so that the push block can fully receive the reverse thrust of the obstacle and effectively transmit the reverse thrust to the electromagnetic drive component, thereby effectively transmitting the reverse thrust to the vehicle, so as to effectively push the vehicle sideways.

[0016] In a possible embodiment, the driver is located on the side of the sliding member facing away from the push block; the driver includes a housing, explosives and a detonator, the housing is provided with an explosion chamber and an air jet connected to the explosion chamber, and the air jet is directed toward the sliding member; the explosives are arranged in the explosion chamber; the detonator is used to detonate the explosives so that the explosives generate gas, and the gas can generate continuous thrust on the sliding member.

[0017] According to the above technical means, the explosive is detonated by the detonator to generate gas, which can generate a large thrust on the sliding member, thereby pushing the sliding member to move quickly toward the obstacle, and then quickly pushing the vehicle sideways.

[0018] In a possible implementation, the sliding member is sealingly connected to the inner wall surface of the accommodating cavity.

[0019] According to the above technical means, the gas generated after the explosion of the explosive will not leak from the gap between the sliding part and the inner wall surface of the accommodating cavity, so that more gas can be used to push the sliding part to slide, thereby increasing the thrust of the sliding part received by the gas and making the sliding part contact the obstacle quickly.

[0020] In a possible implementation, along the height direction of the vehicle, a size of the accommodating cavity is greater than or equal to 160 mm and less than or equal to 200 mm.

[0021] According to the above technical means, the space of the accommodating cavity is large, so that enough explosives can be placed in the accommodating cavity so that the gas generated by the explosion of the explosives can exert thrust on the sliding part for a long enough time so that the ejection assembly can effectively push the vehicle sideways.

[0022] In a possible implementation manner, the duration of the thrust generated by the gas on the sliding member is greater than or equal to 25 ms and less than or equal to 30 ms.

[0023] According to the above technical means, the duration of the thrust generated by the gas on the sliding member within the above range can ensure that the sliding member is in full contact with the obstacle, so that the ejection assembly can effectively push the vehicle sideways.

[0031] In a possible embodiment, the vehicle body includes an anti-collision beam, an energy absorption box and a longitudinal beam, the anti-collision beam is arranged along the width direction of the vehicle; the energy absorption box is connected to the side of the anti-collision beam facing the rear end of the vehicle; the longitudinal beam is connected to the side of the energy absorption box facing away from the anti-collision beam and is arranged along the length direction of the vehicle; the shock tower seat device is connected to the longitudinal beam, and the opening of the installation cavity faces the outer edge of the vehicle in the width direction.

[0032] In a possible embodiment, the vehicle body further includes a pillar and a support beam, one end of the pillar is connected to the longitudinal beam, and the other end of the pillar is used to connect to the chassis of the vehicle; the support beam is located at the outer edge of the vehicle and is located on one side of the shock absorber tower seat device in the width direction of the vehicle, one end of the support beam is connected to the pillar, and the other end of the support beam is used to connect to the A-pillar of the vehicle.

[0033] In a possible embodiment, the angle between the depth direction of the installation cavity of the shock tower seat device and the inner surface of the support beam is greater than 90° and less than 180°, and the opening of the installation cavity is closer to the front end of the vehicle relative to the bottom wall surface of the installation cavity; the direction in which the ejection assembly of the shock tower seat device moves from the first position to the second position is consistent with the depth direction of the installation cavity.

[0037] Therefore, the above technical features of the present application have the following beneficial effects:

[0038] (1) The present invention enables the driver to drive the ejection assembly to move from the first position to the second position when the vehicle is hit by an obstacle. When the ejection assembly is in the second position, the ejection assembly contacts the obstacle and is subjected to a reverse thrust from the obstacle, so that the ejection assembly pushes the vehicle away from the obstacle under the action of the reverse thrust, thereby separating the vehicle from the obstacle and preventing the vehicle from being continuously hit by the obstacle, thereby preventing the structure of the vehicle's cabin from being damaged and ensuring the safety of the passengers in the cabin.

[0039] (2) The present invention enables the ejection assembly to have a relatively simple structure by including a sliding member and a pushing member, thereby facilitating the assembly and setting of the ejection assembly.

[0040] (3) The present invention provides a guide rod and a push block. When a vehicle collides with an obstacle, the push block can contact the obstacle more quickly, thereby pushing the vehicle away from the obstacle more quickly, thereby reducing damage to the vehicle.

[0041] (4) The present invention cooperates with the guide rod and the through hole. When the sliding member pushes the push block to move to the second position through the guide rod, the guide rod can slide in the through hole to guide the push block through the cooperation of the guide rod and the through hole, so as to avoid the push block shaking or deflecting and affecting the effect of pushing the vehicle sideways.

[0042] (5) The present invention can improve the guiding effect of the push block by cooperating with multiple guide rods and multiple through holes.

[0043] (6) The present invention provides an electromagnetic drive component and a magnetic component. As long as the electromagnetic drive component is continuously energized, the electromagnetic drive component can continuously generate a force toward the obstacle on the magnetic component, thereby increasing the contact time between the push block and the obstacle, so that the push block can fully receive the reverse thrust of the obstacle and effectively transmit the reverse thrust to the electromagnetic drive component, thereby effectively transmitting the reverse thrust to the vehicle, thereby effectively pushing the vehicle to move sideways.

[0044] (7) The present invention uses a detonator to detonate explosives to generate gas, which can generate a large thrust on the sliding member, thereby pushing the sliding member to move quickly toward the obstacle, and then quickly pushing the vehicle to move sideways.

[0045] (8) The present invention seals the sliding part to the inner wall of the accommodating chamber. After the explosive explodes, the generated gas will not leak from the gap between the sliding part and the inner wall of the accommodating chamber, so that more gas can be used to push the sliding part to slide, thereby increasing the thrust of the sliding part received by the gas and allowing the sliding part to quickly contact the obstacle.

[0046] (9) The present invention can make the space of the accommodating cavity larger by making the size of the accommodating cavity greater than or equal to 160 mm and less than or equal to 200 mm, so that enough explosives can be placed in the accommodating cavity, so that the gas generated by the explosion of the explosives can generate thrust on the sliding part for a long enough time, so that the ejection assembly can effectively push the vehicle sideways.

[0047] (10) The duration of the thrust force generated by gas on the sliding member of the present invention is greater than or equal to 25 ms and less than or equal to 30 ms, which can ensure that the sliding member is in full contact with the obstacle, so that the ejection assembly can effectively push the vehicle sideways.

[0048] (11) The present invention enables the angle between the direction in which the ejection assembly moves from the first position to the second position and the direction in which the front end of the vehicle points to the rear end to be greater than 90° and less than 180°, so that the reverse thrust generated by the obstacle on the ejection assembly has a component in the length direction of the vehicle, thereby reducing the impact on the vehicle.

[0049] It should be noted that the technical effects brought about by the implementation methods of the second to fourth aspects can refer to the technical effects brought about by the corresponding implementation methods in the first aspect, and will not be repeated here.

DETAILED DESCRIPTION

[0075] In order to enable ordinary persons in the art to better understand the technical solution of the present application, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the accompanying drawings.

[0076] It should be noted that the terms "first", "second", etc. in the specification and claims of the present application and the above-mentioned drawings are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence. It should be understood that the data used in this way can be interchangeable where appropriate, so that the embodiments of the present application described herein can be implemented in an order other than those illustrated or described herein. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present application. On the contrary, they are merely examples of devices and methods consistent with some aspects of the present application as detailed in the attached claims.

[0077] In vehicle collision accidents, 25% offset collision is a relatively common collision form. In the related art, when a vehicle has a 25% offset collision, the front cabin and chassis structure are usually relied on to withstand the impact force or change the direction of the impact force to mitigate the impact suffered by the vehicle. However, this method will damage the front end of the vehicle body and the vehicle body structure at the driver's cabin when the impact force is large, which can easily threaten the safety of the driver and passengers.

[0078] Based on this, the first aspect of the present application provides a vehicle. The vehicle may be a fuel vehicle, a pure electric vehicle, a hybrid electric vehicle, a plug-in hybrid vehicle, an extended-range electric vehicle, etc.

[0079] See also Figure 1 , Figure 1 1 is a schematic diagram of a top view of the front end of a vehicle according to an exemplary embodiment. The vehicle includes a vehicle body 10 and a shock tower assembly 20. The shock tower assembly 20 is connected to the vehicle body 10. The shock tower assembly 20 includes a shock tower body 1. The shock tower body 1 is used to connect the shock absorber of the vehicle. Specifically, one end of the shock absorber is connected to the shock tower body 1, and the other end of the shock absorber is connected to the chassis of the vehicle to reduce shock to the vehicle. The chassis of the vehicle is located on the lower side of the vehicle body 10.

[0080] In some embodiments, see Figure 2 , and combined with Figure 1 , Figure 2 yes Figure 1 , the vehicle body 10 includes an anti-collision beam 101, an energy absorption box 102, a longitudinal beam 103, a pillar 104, and a support beam 105. In some other embodiments, the vehicle body 10 may not include the pillar 104 and the support beam 105.

[0081] The anti-collision beam 101 is arranged along the width direction of the vehicle (eg Figure 1The anti-collision beam 101 is arranged in the direction X1 shown in the figure, that is, the two ends of the anti-collision beam 101 are arranged along the width direction of the vehicle. Among them, the anti-collision beam 101 can be a linear structure or an arc structure. The anti-collision beam 101 can also be a linear structure in the middle part and an arc structure at both ends.

[0082] The energy absorption box 102 is connected to the side of the anti-collision beam 101 facing the rear end of the vehicle. The longitudinal beam 103 is connected to the side of the energy absorption box 102 facing away from the anti-collision beam 101 and is arranged along the length direction of the vehicle, that is, the longitudinal beam 103 can extend along the length direction of the vehicle. In some examples, the number of longitudinal beams 103 is two, and the two longitudinal beams 103 are arranged at intervals along the width direction of the vehicle.

[0083] The column 104 is connected to the longitudinal beam 103, the lower end of the column 104 is connected to the chassis of the vehicle, and the upper end of the column 104 is connected to the front end of the support beam 105. The support beam 105 is located at the outer edge of the vehicle. The support beam 105 is used to support the fender of the vehicle. Exemplarily, the number of the support beams 105 is two, one of the support beams 105 is located on the side of one of the longitudinal beams 103 facing away from the other longitudinal beam 103, and the other support beam 105 is located on the side of the other longitudinal beam 103 facing away from one of the longitudinal beams 103. The number of the columns 104 is also two, and one column 104 is connected to the lower side of one support beam 105.

[0084] The anti-collision beam 101, the energy absorption box 102, the longitudinal beam 103 and the support beam 105 form the bottom frame of the vehicle body 10. The bottom frame is connected to the chassis through the column 104, so that the chassis supports the vehicle body 10.

[0085] In some examples, such as Figure 3 and Figure 4 As shown, Figure 3 yes Figure 1 A top view of the structure at A in the middle. Figure 4 yes Figure 1 A schematic diagram of the structure at position A in the figure is viewed from above. The shock tower assembly 20 is connected to the longitudinal beam 103. Specifically, the shock tower assembly body 1 is connected to the upper side of the longitudinal beam 103. In some examples, the shock tower assembly 20 is located between the anti-collision beam 101 and the lower cross beam 107 of the window frame 106 of the front windshield.

[0086] The number of the shock tower seat bodies 1 can be two, and one shock tower seat body 1 is connected to the upper side of one longitudinal beam 103. The support beam 105 is located on one side of the shock tower seat device 20 in the width direction of the vehicle. For details, please refer to Figure 3, the two shock tower bodies 1 are respectively the first shock tower body 11 and the second shock tower body 12, and the two support beams 105 are respectively the first support beam 1051 and the second support beam 1052. The first support beam 1051 is located on the side of the first shock tower body 11 facing away from the second shock tower body 12, and the second support beam 1052 is located on the side of the second shock tower body 12 facing away from the first shock tower body 11. In some examples, the side of the first shock tower body 11 facing away from the second shock tower body 12 overlaps with the first support beam 1051. The side of the second shock tower body 12 facing away from the first shock tower body 11 overlaps with the second support beam 1052.

[0087] When the vehicle is hit by an obstacle, such as a 25% offset collision, the anti-collision beam 101 of the vehicle usually collides with the obstacle first, at which time the energy absorption box 102 will deform, thereby absorbing part of the energy generated by the collision to reduce the damage caused by the collision to the longitudinal beam 103. In addition, the vehicle will deviate after being hit by the obstacle, so that the support beam 105 collides with the obstacle, thereby reducing the collision force on the vehicle.

[0088] If the impact force on the vehicle is large and the support beam 105 is damaged, the vehicle body structure at the vehicle cabin, such as the door, may collide with an obstacle, which may cause damage to the vehicle body structure at the vehicle cabin and affect the personal safety of the passengers in the cabin.

[0089] It should be noted that obstacles may be other vehicles, or stones, trees, buildings, etc. on the side of the road.

[0090] To avoid this, see Figure 5 and Figure 6 , Figure 5 yes Figure 1 The schematic diagram of the cross-sectional structure of the shock tower assembly in the vehicle when viewed from the front is shown in FIG. Figure 6 yes Figure 5 The enlarged schematic diagram of the ejection assembly in the structure at B is in the first position. The shock tower device 20 includes a shock tower body 1 and a force transmission assembly 2.

[0091] See also Figure 7 , Figure 8 and Fig. 9 , Figure 7 is a schematic diagram of a top view of a shock absorbing tower body according to an exemplary embodiment. Figure 8 yes Figure 7 The side view of the shock tower body is shown in FIG. Fig. 9 yes Figure 7 The front view of the shock tower body is shown in FIG. The shock tower body 1 is provided with an opening on one side (such as Figure 8 and Fig. 9The force transmission component 2 is arranged in the installation cavity 13. The force transmission component 2 is used to contact the obstacle and receive the reverse thrust of the obstacle when the vehicle is hit by the obstacle, so as to push the vehicle to move away from the obstacle, thereby preventing the obstacle from colliding with the body structure of the vehicle at the passenger compartment, thereby preventing the driver and passengers from being injured. The reverse thrust refers to the reaction force of the obstacle received by the force transmission component 2 after contacting the obstacle, that is, the direction of the reverse thrust is from the obstacle to the force transmission component 2.

[0092] By setting an installation cavity 13 on the shock tower seat body 1 and placing the force transmission component 2 in the installation cavity 13, the force transmission component 2 can be protected by the shock tower seat body 1, and the structure and space of the shock tower seat body 1 can be reasonably utilized to reduce the space occupied by the force transmission component 2 on the vehicle body 10, thereby reducing the arrangement of various components of the vehicle body 10, thereby facilitating the arrangement of the force transmission component 2 and other components of the vehicle body 10.

[0093] Furthermore, since the support beam 105 is located at the edge of the vehicle and on one side of the shock tower seat device 20 in the width direction of the vehicle, the force transmission component 2 is disposed in the installation cavity 13 of the shock tower seat body 1, and the support beam 105 can also protect the force transmission component 2, and when the vehicle is hit by an obstacle, the obstacle is prevented from directly hitting the force transmission component 2 and causing damage to the force transmission component 2.

[0094] In some embodiments, see Fig.10 , Fig.11 and Fig.12 , Fig.10 is a schematic diagram of the overall structure of a force transmission component according to an exemplary embodiment. Fig.11 yes Fig.10 The schematic diagram of the relationship between the driver of the force transmission component and the ejection component is shown in FIG. Fig.12 yes Fig.10 The cross-sectional structure diagram of the force transmission component shown in FIG. The force transmission component 2 includes a housing 21, an ejection component 22 and a driver 23. Please continue to refer to Figure 2 , the shell 21 is fixed to the vehicle. Exemplarily, the shell 21 is disposed in the mounting cavity 13 of the shock tower body 1 and is fixedly connected to the shock tower body 1. The shell 21 can be connected to the mounting cavity 13 by interference fit, or can be connected to the shock tower body 1 by screw connection, welding, etc. The shell 21 can be a box-shaped structure, a groove-shaped structure, a cover-shaped structure, etc.

[0095] The ejection assembly 22 is connected to the housing 21 and can move relative to the housing 21. The driver 23 is connected to the housing 21, and when the vehicle is hit by an obstacle, the driver 23 can drive the ejection assembly 22 to move from the first position to the second position.

[0096] See also Fig.13 , Fig.13 yes Figure 5 FIG. 2 is an enlarged schematic diagram of the ejection assembly 22 in the structure at position B in the middle when the ejection assembly 22 is in the second position. When the ejection assembly 22 is in the second position, the ejection assembly 22 contacts the obstacle and is blocked by the obstacle (such as Fig.13 The reverse thrust of the obstacle N) is provided so that the ejection assembly 22 pushes the vehicle away from the obstacle under the action of the reverse thrust.

[0097] In this way, when the vehicle is hit by an obstacle, the driver 23 can drive the ejection assembly 22 to move from the first position to the second position. When the ejection assembly 22 moves to the second position, the ejection assembly 22 contacts the obstacle and squeezes the obstacle, so that the obstacle can generate a reaction force, i.e., a reverse thrust, on the ejection assembly 22. At the same time, since the driver 23 has a driving force on the ejection assembly 22, the ejection assembly 22 will generate a thrust on the driver 23 and the housing 21 under the action of the reverse thrust, thereby generating a thrust on the vehicle to push the vehicle to move in the direction away from the obstacle, thereby separating the vehicle from the obstacle, preventing the vehicle from being continuously hit by the obstacle, and preventing the structure of the vehicle's cabin from being damaged, thereby ensuring the safety of the passengers in the cabin.

[0098] When the ejection assembly 22 is located at the first position, the ejection assembly 22 is located at the inner side of the edge of the vehicle, that is, along the height direction of the vehicle, the ejection assembly 22 is blocked by the vehicle body 10. In some examples, when the ejection assembly 22 is located at the first position, the ejection assembly 22 is located in the installation cavity 13 of the shock tower body 1. When the ejection assembly 22 moves from the first position to the second position, the ejection assembly 22 can extend out of the installation cavity 13 through the opening of the installation cavity 13.

[0099] See also Fig.14 and Fig.15 , Fig.14 is a simulation effect diagram showing a vehicle body frame resisting an obstacle when a vehicle collides according to an exemplary embodiment. Fig.15 The figure is a simulation effect diagram showing the sideways displacement of a vehicle by a force transmission component when a vehicle collides according to an exemplary embodiment. Fig.14 It can be seen from the collision structure that the body frame will cause a large area of ​​damage to the body frame if it is used to resist obstacles. If the collision force is large, it may continue to damage the A-pillar 108, the front door 109, the lower cross beam 107 of the front windshield window frame 106 and other structures of the vehicle, thereby posing a threat to the safety of the driver and passengers. Fig.15It can be seen from the collision results that when the vehicle collides, the force transmission component pushes the vehicle sideways, and only the edge of the vehicle collides with the obstacle and is damaged. The damage to the vehicle's A-pillar 108, front door 109, lower cross beam 107 of the front windshield window frame 106 and other structures is relatively small, which can reduce the damage to the driver and passengers and improve the safety of the driver and passengers.

[0100] For some examples, see Figure 2 , the support beam 105 may include a straight segment 1054 and an arc segment 1055. One end of the arc segment 1055 is connected to the pillar 104, the other end of the arc segment 1055 is connected to one end of the straight segment 1054, and the other end of the straight segment 1054 is connected to the A-pillar 108 of the vehicle. In other words, the straight segment 1054 is connected to one side of the arc segment 1055 close to the rear end of the vehicle.

[0101] The arc segment 1055 is arched toward the front end of the vehicle. The straight segment 1054 is located on the upper side of the column 104; the mounting cavity 13 of the shock tower assembly 20 is located inside the arc segment 1055. Since the force transmission component 2 is disposed in the mounting cavity 13, the force transmission component 2 is located inside the arc segment 1055.

[0102] In this way, when the vehicle collides with an obstacle, the energy absorbing box 102 will first absorb part of the energy generated by the collision, and then the arc segment 1055 of the support beam 105 will collide with the obstacle. At this time, since the arc segment 1055 is arched toward the front end of the vehicle, that is, arched toward the front direction of the vehicle, the arc segment 1055 will also unload part of the energy generated by the collision after colliding with the obstacle.

[0103] After the arc segment 1055 collides with an obstacle, the arc segment 1055 will be deformed. At this time, the force transmission component 2 can move the ejection component 22 from the first position to the second position according to the deformation of the arc segment 1055, so that the ejection component 22 contacts the obstacle and pushes the vehicle to move sideways, thereby reducing the damage to the vehicle.

[0104] In some examples, since the support beam 105 is located at the edge of the vehicle and at one side of the shock tower assembly 20 in the width direction of the vehicle, the ejection assembly 22 may be blocked by the support beam 105 during the process of moving from the first position to the second position. In order to prevent the support beam 105 from blocking the ejection assembly 22, please refer to Fig.16 , Fig.16 yes Figure 1 In the side view of the structure at A in the middle, a relief through hole 1053 is provided on the support beam 105. The axial direction of the relief through hole 1053 is perpendicular to the plane where the opening of the installation cavity 13 is located, and along the axial direction of the relief through hole 1053, the projection of the ejection assembly 22 does not exceed the projection range of the relief through hole 1053.

[0105] In some embodiments, in order to facilitate the control of the driver 23 to drive the ejection assembly 22 to move from the first position to the second position, the vehicle further includes a sensor and a controller. The sensor is connected to the vehicle body 10. Exemplarily, the sensor can be connected to the anti-collision beam 101, or to the support beam 105, or to the shock tower body 1 of the shock tower device 20.

[0106] The sensor is used to detect the collision signal of the vehicle. For example, the sensor can detect the collision signal of the anti-collision beam 101 and the collision signal of the support beam 105. The present application uses the sensor connected to the shock tower body 1 to detect the collision signal of the support beam 105 for example.

[0107] In some examples, the sensor may be a displacement sensor. In this case, the collision signal detected by the sensor is a displacement signal. Specifically, when the sensor detects that the distance between the collision object and the sensor is smaller than the distance between the outer edge of the support beam 105 and the sensor, it means that the support beam 105 has collided with the obstacle. In other examples, the sensor may also be a strain sensor. In this case, the collision signal detected by the sensor is a deformation signal of the support beam 105. Specifically, the sensing surface of the sensor contacts the support beam 105. When the support beam 105 collides with the obstacle, the support beam 105 will be deformed by the collision of the obstacle, thereby causing the sensor to deform, so that the sensor detects the deformation signal of the support beam 105.

[0108] The controller is electrically connected to the sensor and is used to receive the collision signal detected by the sensor. The controller is electrically connected to the force transmission component of the shock tower device 20. Specifically, the controller is electrically connected to the driver 23 of the force transmission component 2.

[0109] The controller is configured to obtain a collision signal and determine whether the vehicle is collided with an obstacle; if the vehicle is collided with the obstacle, the force transmission component 2 of the vehicle is controlled to start, and the driver 23 of the force transmission component 2 drives the ejection component 22 of the force transmission component 2 to move from the first position to the second position to move the vehicle away from the obstacle.

[0110] In this way, the sensor can quickly identify whether the vehicle collides with an obstacle, and the controller can quickly respond after receiving the signal from the sensor to control the driver 23 to work, thereby quickly driving the ejection assembly 22 to move from the first position to the second position, so that the vehicle is quickly separated from the obstacle, reducing the damage caused by the obstacle to the vehicle, and reducing the damage caused by the obstacle to the driver and passengers.

[0111] The time from when the controller receives the collision signal from the sensor to when the driver 23 is controlled to drive the ejection assembly 22 to move to the second position can be less than or equal to 2 ms, so that the force transmission assembly 2 can quickly push the vehicle away and reduce damage to the vehicle.

[0112] In some embodiments, see Fig.17 , Fig.17 yes Figure 3 In order to more effectively separate the vehicle from the obstacle, the angle between the depth direction of the installation cavity 13 and the inner surface of the support beam 105 (such as Fig.17 The angle β shown in the figure is greater than 90° and less than 180°, and the opening of the installation cavity 13 is closer to the front end of the vehicle relative to the bottom wall surface of the installation cavity 13. In other words, relative to the inner surface of the support beam 105, the installation cavity 13 gradually tilts toward the front end of the vehicle from the bottom wall surface to the opening direction. Among them, the angle between the depth direction of the installation cavity 13 and the inner surface of the support beam 105 is 100°, 110°, 120°, 130°, 140°, 150°, 160°, 170°, etc.

[0113] It should be noted that, since the installation cavity 13 has an opening on only one side, the inner wall surface of the installation cavity 13 opposite to the opening is the bottom wall surface of the installation cavity 13. The depth direction of the installation cavity 13 is the arrangement direction of the opening of the installation cavity 13 and the bottom wall surface of the installation cavity 13. The inner side surface of the support beam 105 is the side surface of the support beam 105 facing away from the outer edge of the vehicle along the width direction of the vehicle. For example, the side surface of the first support beam 1051 facing the second support beam 1052 is the inner side surface of the first support beam 1051.

[0114] The direction in which the ejection assembly 22 of the shock tower assembly 20 moves from the first position to the second position is consistent with the depth direction of the installation cavity 13 .

[0115] Through the above arrangement, the angle between the direction in which the ejection assembly 22 moves from the first position to the second position and the direction in which the front end of the vehicle points to the rear end (such as Fig.17 The angle β shown in the figure is greater than 90° and less than 180°. In this way, the reverse thrust generated by the obstacle on the ejection assembly 22 will have a component in the length direction of the vehicle, thereby reducing the impact on the vehicle. It can also prevent the middle position of the vehicle (such as the A-pillar 108, the front door 109, etc.) from swinging towards the obstacle with a large amplitude after the front end of the vehicle is pushed away from the obstacle, so as to avoid the middle position of the vehicle from colliding with the obstacle, so as to effectively separate the vehicle from the obstacle and reduce the damage to the vehicle.

[0116] In some embodiments, please refer to Fig.11 and Fig.12The ejection assembly 22 includes a sliding member 221 and a pushing member 222. The sliding member 221 is slidably connected to the housing 21, and the driver 23 can drive the sliding member 221 to slide, so that the ejection assembly 22 moves relative to the housing 21. Exemplarily, the sliding member 221 can be a block structure, a plate structure, etc., or a structure composed of a block, a plate, a rod, etc.

[0117] The pusher 222 is connected to the slide 221. When the ejection assembly 22 is in the second position, the pusher 222 contacts the obstacle and is subjected to the reverse thrust of the obstacle. That is, when the vehicle collides with the obstacle, the driver 23 can drive the slide 221 to slide from the first position to the second position relative to the housing 21, and the slide 221 drives the pusher 222 to move toward the obstacle. Until the ejection assembly 22 moves to the second position, the pusher 222 contacts the obstacle and squeezes the obstacle, so that the obstacle generates a reverse thrust on the pusher 222, so that the pusher 222 pushes the vehicle away from the obstacle through the slide 221 and the housing 21.

[0118] Since the ejection assembly 22 includes the sliding member 221 and the pushing member 222 , the structure of the ejection assembly 22 can be made simpler, thereby facilitating the assembly and arrangement of the ejection assembly 22 .

[0119] Exemplarily, the sliding member 221 and the shell 21 can be connected by a slide rail slider structure, or by a slider slot structure. Also exemplarily, a housing chamber 211 and a through hole 212 connected to the housing chamber 211 are formed in the shell 21. The sliding member 221 is located in the housing chamber 211 and can slide in the housing chamber 211. That is, the sliding member 221 is limited by the inner wall surface of the housing chamber 211 so that the sliding member 221 slides relative to the shell 21. At this time, when the ejection assembly 22 is in the first position, the pushing member 222 can be completely located in the housing chamber 211, or it can be partially located in the housing chamber 211, and the other part passes through the through hole 212 and is located outside the housing chamber 211. During the movement of the ejection assembly 22 from the first position to the second position, the pushing member 222 can move toward the obstacle through the through hole 212.

[0120] In some examples, since 25% offset collision is common in vehicle collision accidents, the opening of the mounting cavity 13 can be made to face the outer edge of the vehicle in the width direction. For example, for the first shock tower and the first support beam 1051 , the opening of the mounting cavity 13 can face the first support beam 1051 .

[0121] In this way, when the vehicle collides with an obstacle, the anti-collision beam 101 may collide with the obstacle first, so that the energy absorption box 102 can first mitigate the collision of the vehicle, and then when the support beam 105 collides with the obstacle, the impact force on the vehicle is reduced. At this time, the ejection component 22 can more effectively push the vehicle away from the obstacle.

[0122] Furthermore, the opening of the installation cavity 13 faces the outer edge of the vehicle in the width direction, and the reverse thrust received by the ejection assembly 22 is mainly along the width direction of the vehicle. Thus, the vehicle will move laterally along the width direction under the reverse thrust, so that the ejection assembly 22 can more easily push the vehicle away from obstacles.

[0123] In some examples, at least a portion of the pusher 222 is located at the opening of the mounting cavity 13. In this way, the mounting cavity 13 can provide a certain degree of protection for the pusher 222. When the vehicle collides with an obstacle, the pusher 222 can quickly move to the outside of the mounting cavity 13 and contact the obstacle to quickly push the vehicle away from the obstacle.

[0124] In some embodiments, the push member 222 includes a guide rod 2221 and a push block 2222. One end of the guide rod 2221 is connected to the sliding member 221, and the other end of the guide rod 2221 is connected to the push block 2222. In some examples, the push block 2222 can be located at the opening of the mounting cavity 13. Among them, the push block 2222 can block the opening of the mounting cavity 13. When the ejection assembly 22 is in the second position, the push block 2222 contacts the obstacle and is subjected to the reverse thrust of the obstacle. When the vehicle collides with the obstacle, the driver 23 drives the sliding member 221 to slide from the first position to the second position relative to the housing 21, and at this time, the sliding member 221 drives the push block 2222 to move toward the obstacle through the guide rod 2221. Until the ejection assembly 22 moves to the second position, the push block 2222 contacts and squeezes the obstacle, so that the obstacle generates a reverse thrust on the push block 2222, so that the push block 2222 pushes the vehicle away from the obstacle through the guide rod 2221, the sliding member 221, and the housing 21.

[0125] By setting the guide rod 2221 and the push block 2222, the distance between the push block 2222 and the sliding member 221 can be increased, that is, when the ejection assembly 22 is in the first position, the push block 2222 is closer to the outer edge of the vehicle, so that when the vehicle collides with an obstacle, the push block 2222 can contact the obstacle faster, and then the vehicle can be pushed away from the obstacle faster to reduce damage to the vehicle.

[0126] Moreover, compared with the block structure, the guide rod 2221 is smaller in size, which can save materials, so that the sliding member 221, the guide rod 2221 and the push block 2222 have a smaller mass as a whole, so that they can be pushed quickly, so that the push block 2222 can quickly contact the obstacle.

[0127] In addition, compared with the rod-shaped structure, the push block 2222 has a larger contact area with the obstacle, which can reduce the pressure on the push block 2222, the guide rod 2221 and the sliding member 221 as a whole, thereby reducing the damage to the ejection assembly 22.

[0128] The materials of the push block 2222, the guide rod 2221 and the sliding member 221 can all be high-strength steel materials such as Q390, Q420, AH70, etc., so that the ejection assembly 22 has good strength, can withstand the reverse thrust of obstacles, and provide effective thrust to the vehicle to keep the vehicle away from obstacles.

[0129] In some embodiments, when the housing 21 is provided with a receiving cavity 211 and a through hole 212 communicating with the receiving cavity 211, the push block 2222 may be located at the opening of the receiving cavity 211. The push block 2222 may block the through hole 212. In other embodiments, the push block 2222 may be located outside the receiving cavity 211, and the guide rod 2221 may be passed through the through hole 212. In this way, when the sliding member 221 pushes the push block 2222 to move to the second position through the guide rod 2221, the guide rod 2221 may slide in the through hole 212, so as to guide the push block 2222 through the cooperation between the guide rod 2221 and the through hole 212, so as to avoid the push block 2222 from shaking or deviating and affecting the effect of pushing the vehicle to move sideways.

[0130] In some embodiments, there are multiple guide rods 2221 , multiple through holes 212 , and one guide rod 2221 is disposed in one through hole 212 .

[0131] In this way, the structural strength of the ejection assembly 22 can be improved by connecting the sliding member 221 and the push block 2222 through a plurality of guide rods 2221. In addition, the plurality of guide rods 2221 cooperate with a plurality of through holes 212 to improve the guiding effect on the push block 2222. In addition, the plurality of guide rods 2221 can be evenly distributed so that the force transmission between the push block 2222 and the sliding member 221 is relatively uniform.

[0132] In some embodiments, the driving member includes an electromagnetic driving member. For example, the driving member can be an electromagnet, an electromagnetic coil, etc. The sliding member 221 includes a magnetic member. For example, the magnetic member can be a magnet, a permanent magnet, an electromagnet, an electromagnetic coil, etc. The magnetic member can be connected to the push block 2222 through the guide rod 2221.

[0133] The electromagnetic drive member is located on the side of the magnetic member facing away from the push block 2222. When the vehicle is hit by an obstacle, the polarity of the end of the electromagnetic drive member facing the magnetic member is the same as the polarity of the end of the magnetic member facing the electromagnetic drive member. Exemplarily, if the polarity of the end of the electromagnetic drive member facing the magnetic member is an N pole, then the polarity of the end of the magnetic member facing the electromagnetic drive member is also an N pole. Another exemplary embodiment, if the polarity of the end of the electromagnetic drive member facing the magnetic member is an S pole, then the polarity of the end of the magnetic member facing the electromagnetic drive member is also an S pole.

[0134] In this way, when the vehicle collides with an obstacle, the electromagnetic drive component can be energized. Specifically, the controller can control the power supply to energize the electromagnetic drive component.

[0135] Since the polarity of the end of the electromagnetic driving member facing the magnetic member is the same as the polarity of the end of the magnetic member facing the electromagnetic driving member, the electromagnetic driving member can generate a force on the magnetic member to move the magnetic member toward the obstacle, thereby pushing the magnetic member to move toward the obstacle, and then pushing the push block 2222 to move toward the obstacle.

[0136] The electromagnetic drive method has the characteristics of high stability and fast response speed. Through the cooperation of the electromagnetic drive component and the magnetic component, the magnetic component can quickly and stably push the push block 2222 to move from the first position to the second position.

[0137] Furthermore, as long as the electromagnetic drive component is continuously energized, it can ensure that the electromagnetic drive component continuously generates a force toward the obstacle on the magnetic component, thereby increasing the contact time between the push block 2222 and the obstacle, so that the push block 2222 can fully receive the reverse thrust of the obstacle and effectively transfer the reverse thrust to the electromagnetic drive component, thereby effectively transferring the reverse thrust to the vehicle, thereby effectively pushing the vehicle to move sideways.

[0138] In addition, since the magnetic component and the electromagnetic driving component are not in direct contact, when the push block 2222 contacts the obstacle, the air between the magnetic component and the electromagnetic driving component can buffer the magnetic component and the electromagnetic driving component to avoid damage to the magnetic component and the electromagnetic driving component.

[0139] In some other embodiments, the driver 23 is located on the side of the sliding member 221 facing away from the push block 2222. Fig.12 The driver 23 includes a housing 231, an explosive 232 and a detonator 233. The housing 231 is provided with an explosion chamber 2311 and an air jet 2312 connected to the explosion chamber 2311, and the air jet 2312 faces the sliding member 221. The explosive 232 is arranged in the explosion chamber 2311. The detonator 233 is used to detonate the explosive 232 so that the explosive 232 generates gas, and the gas can generate a continuous thrust on the sliding member 221. The detonator 233 can be arranged in the housing 231, can be arranged in the housing 21, and can also be arranged in the shock tower body 1.

[0140] When the vehicle collides with an obstacle, the explosive 232 can be detonated by the detonator 233. Specifically, the detonator 233 can be started by the controller to detonate the explosive 232.

[0141] After the explosion of the explosive 232, a large amount of gas can be generated, and the gas is ejected to the sliding member 221 through the jet port 2312 to generate a thrust toward the obstacle on the sliding member 221, thereby pushing the sliding member 221 to move toward the obstacle, so that the sliding member 221 contacts the obstacle and receives the reverse thrust of the obstacle, thereby pushing the vehicle to move sideways.

[0142] The explosive 232 is detonated by the detonator 233 to generate gas, which can generate a large thrust on the sliding member 221, thereby pushing the sliding member 221 to move quickly toward the obstacle, thereby quickly pushing the vehicle to move sideways. In addition, when the push block 2222 contacts the obstacle, the gas can buffer the box 231 and the sliding member 221 to prevent the box 231 and the sliding member 221 from being damaged.

[0143] It should be noted that the gas generated by the explosive has a relatively high pressure, so that the gas can push the sliding member 221 to slide. In some examples, the blasting agent can be water gel explosive or emulsion explosive.

[0144] On this basis, the sliding member 221 can be sealed and connected to the inner wall surface of the accommodating chamber 211. In this way, the gas generated after the explosion of the explosive 232 will not leak from the gap between the sliding member 221 and the inner wall surface of the accommodating chamber 211, so that more gas can be used to push the sliding member 221 to slide, thereby increasing the thrust of the sliding member 221 received by the gas and making the sliding member 221 contact the obstacle quickly.

[0145] At this time, a pressure relief valve can be provided on the housing 21, and the pressure relief valve is connected to the part of the accommodating chamber 211 located on the side of the sliding member 221 facing away from the push block 2222. After the ejection assembly 22 pushes the vehicle to move sideways, the pressure relief valve can be controlled to open to discharge the gas.

[0146] In some embodiments, in order to enable the gas generated by the explosion of the explosive 232 to generate a thrust on the sliding member 221 for a sufficiently long time, the size of the accommodating chamber 211 in the height direction of the vehicle can be greater than or equal to 160 mm and less than or equal to 200 mm. For example, the size of the accommodating chamber 211 in the height direction of the vehicle can be 160 mm, 165 mm, 170 mm, 175 mm, 180 mm, 185 mm, 190 mm, 195 mm, 200 mm, etc. In this way, the space of the accommodating chamber 211 can be larger, so that enough explosives 232 can be placed in the accommodating chamber 211, so that the gas generated by the explosion of the explosive 232 can generate a thrust on the sliding member 221 for a sufficiently long time, so that the ejection assembly 22 can effectively push the vehicle to move sideways.

[0147] It should be noted that the dimensions of the box 231 containing the explosive 232 in the vehicle height direction and the vehicle length direction can match the accommodating cavity 211 to ensure the amount of the explosive 232 contained in the box 231. In addition, the shock tower seat body 1 needs to support the shock absorber, and the shock tower seat body 1 needs to have a certain structural strength. Therefore, the size of the accommodating cavity 211 is limited by the structure and size of the shock tower.

[0148] In some embodiments, the duration of the thrust generated by the gas generated by the explosion of the explosive 232 on the sliding member 221 is greater than or equal to 25 ms and less than or equal to 30 ms. For example, the duration of the thrust generated by the gas on the sliding member 221 can be 25 ms, 26 ms, 27 ms, 28 ms, 29 ms, 30 ms, etc.

[0149] The duration of the thrust generated by the gas on the sliding member 221 within the above range can ensure that the sliding member 221 is in full contact with the obstacle, so that the ejection assembly 22 can effectively push the vehicle to move sideways.

[0150] In a second aspect of the present application, a vehicle control method is also provided. Fig.18 , Fig.18 is a flow chart of a control method according to an exemplary embodiment. The control method includes:

[0151] S1: Obtaining collision information of the vehicle to determine whether the vehicle is collided with an obstacle;

[0152] S2: If the vehicle is hit by an obstacle, the force transmission component 2 of the vehicle is controlled to start, and the driver 23 of the force transmission component 2 drives the ejection component 22 of the force transmission component 2 to move from the first position to the second position, so that the vehicle is away from the obstacle.

[0153] If the vehicle is not hit by an obstacle, the force transmission component 2 of the vehicle is controlled not to start.

[0154] The above are only specific implementations of the present application, but the protection scope of the present application is not limited thereto, and any changes or substitutions within the technical scope disclosed in the present application should be included in the protection scope of the present application. Therefore, the protection scope of the present application should be based on the protection scope of the claims.
