[0048] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0049] It should be noted that if the embodiments of this application involve directional indicators (such as up, down, left, right, front, back, etc.), the directional indicators are only used to explain the relative positional relationship and movement of the components in a specific posture. If the specific posture changes, the directional indicators will also change accordingly.

[0050] Furthermore, if the embodiments of this application involve descriptions such as "first" or "second," these descriptions are for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated.

When the combination of technical solutions is contradictory or impossible to implement, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection claimed in this application.

[0051] For vehicles such as electric vehicles, gasoline-powered vehicles, or hybrid vehicles, protective measures in the event of a collision with a pedestrian or other moving object are usually required.

[0052] Taking vehicles as an example, related technologies aim to reduce injury by optimizing the design of the car's hood, such as through optimized styling, overall layout, structural design, and material selection. However, because the overall vehicle performance, including aesthetics, strength and durability, and ease of maintenance, must be considered, these optimizations are not very effective in protecting pedestrians. This could result in greater injuries and a higher risk of fractures for pedestrians in collisions with vehicles.

[0053] Therefore, this application proposes a means of transportation and a collision protection method to help reduce collision injuries to pedestrians and other moving objects.

[0054] Reference Figure 1 , Figure 2 and Figure 3 In one embodiment of this application, the vehicle 100 includes a passenger compartment 110, a housing compartment 120, a support structure 130, and a collision detection device. This vehicle includes, but is not limited to, electric vehicles, gasoline-powered vehicles, or hybrid vehicles, as well as ships and aircraft. Figure 1 A top view of the vehicle 100 in this embodiment is shown. Figure 2 A rear view of a partial structure of the vehicle 100 in this embodiment is shown. Figure 3 A left view showing a partial structure of the vehicle 100 in this embodiment is shown.

[0055] The passenger compartment 110 is used to carry passengers; for example, the passenger compartment 110 may include a cockpit and a passenger compartment. The accommodating compartment 120 and the passenger compartment 110 are arranged along the direction of travel of the vehicle 100, for example, along... Figure 1The compartment 120 is arranged in a front-to-back direction. It includes a hatch 121 and a body with a receiving cavity, the hatch 121 covering the opening of the receiving cavity. Taking a vehicle 100 as an example, the compartment 120 can be a front compartment, and the hatch 121 can be a front hatch corresponding to the front compartment. Since pedestrians and other moving objects may be involved in a collision when the vehicle is reversing, the compartment 120 can also be a trunk, and the hatch 121 can be a rear hatch corresponding to the trunk.

[0056] The support device 130 includes a support rod 133. One end of the support rod 133 is driven to move by the support device 130, meaning the support device 130 can output power outward by driving the support rod 133 to move. The other end of the support rod 133 is connected to the hatch 121. The support rod 133 is used to move at least a portion of the hatch 121 away from the cabin along the height direction of the vehicle 100, for example, to... Figure 3 The right side portion of the central hatch 121 rotates upward and away from the hatch, thus forming... Figure 4 The hatch 121 can be located away from the cabin in a state that is far from the cabin body; of course, the hatch 121 can also be located entirely away from the cabin body, and this embodiment does not limit this.

[0057] In some embodiments, the support device 130 may further include a conveying device 131 and a closed housing 132. The conveying device 131 communicates with the closed inner cavity of the closed housing 132, and the conveying device 131 is used to convey fluid into the closed inner cavity. The closed housing 132 includes a movable portion for bearing the fluid pressure of the closed inner cavity; one end of the support rod 133 is connected to the movable portion, so that the support device 130 can move the movable portion and the support rod 133 by adjusting the fluid pressure of the closed inner cavity. It is understood that the conveying device 131 may be configured as a pump body, which can communicate with the closed inner cavity of the closed housing 132 through a pipeline. For example, the conveying device 131 may be configured as a hydraulic pump; correspondingly, the support device 130 may include a hydraulic strut, wherein the housing of the hydraulic strut is configured as the closed housing 132, and the telescopic rod of the hydraulic strut is configured as the support rod 133. In this case, the support device 130 may also include a corresponding reversing valve, a hydraulic oil tank, pipelines, etc.

[0058] In some embodiments, the movable part can divide the enclosed cavity into a first sub-cavity and a second sub-cavity, and the conveying device 131 connects the first sub-cavity and the second sub-cavity respectively. The conveying device 131 is used to create a preset pressure difference between the fluid pressure in the first sub-cavity and the fluid pressure in the second sub-cavity, so that the hatch cover 121 is held in a preset position away from the cabin body. For example, the enclosed shell 132 can be cylindrical, and the movable part can be configured as a piston to divide the inner cavity of the cylindrical enclosed shell 132 into a first sub-cavity and a second sub-cavity. Thus, the conveying device 131 can conveniently and quickly create a preset pressure difference between the first sub-cavity and the second sub-cavity by changing the fluid pressure in the first sub-cavity and the second sub-cavity respectively. The preset pressure difference can be set according to the weight of the hatch cover 121. In addition, the conveying device 131 can adjust the pressure difference by increasing the fluid pressure in the first sub-cavity and decreasing the fluid pressure in the second sub-cavity, thereby conveniently and quickly adjusting the supporting force of the support rod 133 on the hatch cover 121.

[0059] Of course, in other embodiments, the conveying device 131 can be configured as a gas pump, and the enclosed housing 132 and the support rod 133 can be respectively configured as the outer shell of the pneumatic strut and the telescopic rod. This embodiment does not limit this.

[0060] Alternatively, the support device 130 can also be configured as an electric push rod, telescopic arm, etc., and this embodiment does not limit it in this way.

[0061] Furthermore, the aforementioned collision detection device is used to detect collision information between the target moving body and the vehicle 100. The collision detection device is used to adjust the supporting force of the support rod 133 on the hatch 121 based on the collision information. This can be understood as the collision detection device being electrically connected to the support device 130, thereby adjusting the driving force of the support device 130 on the support rod 133 based on the aforementioned collision information. Further, the aforementioned collision detection device can be communicatively connected to the conveying device 131, allowing the conveying device 131 to adjust the fluid pressure in the closed cavity based on the collision information, thereby adjusting the supporting force of the support rod 133 on the hatch 121. The collision information includes information characterizing a possible collision, such as information about the moving body's proximity to the vehicle 100; of course, the collision information can also include information about the moment of collision, such as the collision force between the moving body and the vehicle 100. In some embodiments, the collision detection device may include object sensors such as cameras, lidar, millimeter-wave radar, ultrasonic radar, and infrared sensors, thereby acquiring object data information on the side of the accommodating compartment 120 facing away from the passenger compartment 110 (e.g., in...). Figure 1The collision detection device acquires object data information from the front side of the accommodating compartment 120, including images, laser point clouds, etc. Furthermore, it identifies moving targets such as pedestrians based on this object data information and obtains the distance between the moving target and the vehicle 100. Additionally, the collision detection device may include a velocity sensor that detects at least one of acceleration, velocity, angular velocity, and angular acceleration to obtain the vehicle 100's speed. Based on the aforementioned distance and speed, at least a portion of the hatch 121 is moved away from the compartment along the height direction of the vehicle 100, and the supporting force on the hatch 121 is adjusted. It can be understood that the collision detection device can acquire object data information on the side of the accommodating compartment 120 facing away from the passenger compartment 110. The collision detection device may also include a processor, which identifies moving targets and the distance between the moving targets and the vehicle 100 based on the object data information, specifically through existing image recognition technology. Furthermore, the collision detection device may include a velocity sensor, which obtains the vehicle 100's speed, and the processor outputs collision information based on the distance and speed.

[0062] It is understandable that the aforementioned object sensors, such as cameras, lidar, millimeter-wave radar, ultrasonic radar, and infrared sensors, as well as speed sensors, can be installed on the vehicle 100. Of course, the aforementioned object sensors and speed sensors can also be installed outside the vehicle 100, and the collision information can be transmitted to the vehicle 100 through wired, wireless, or other communication links.

[0063] In some embodiments, the conveying device 131 can also be used to adjust the distance between at least a portion of the hatch 121 and the cabin body according to the collision information. This can be understood as adjusting the lifting height of the hatch 121, thereby adjusting the size of the deformation space between the hatch 121 and the cabin body, so as to be suitable for different scenarios, including different spatial conditions of different types of vehicles 100.

[0064] In the above-described embodiment of the vehicle 100, when a pedestrian or other moving body collides with the hatch 121, at least the portion away from the hatch has a larger deformation space between it and the hatch. Thus, the hatch 121 itself can absorb collision energy by forming a larger deformation, thereby reducing the collision damage suffered by pedestrians or other moving bodies.

[0065] Furthermore, in an optional embodiment where the support device 130 includes a conveying device 131 and a closed housing 132, the support device 130 can further absorb collision energy through fluid compression within the closed cavity, and can further absorb energy by adjusting the supporting force of the support rod 133 on the hatch 121. In addition, by using the conveying device 131 to convey fluid into the closed cavity, the support device 130 can be reused in the absence of a collision, avoiding unnecessary maintenance costs, reducing the overall cost of the support device 130, and making the support device 130 more economical.

[0066] In some embodiments, the side of the hatch 121 away from the crew compartment 110 is rotatably connected to the cabin body, for example... Figure 3 , Figure 4 The front side of the hatch 121 is rotatably connected to the cabin body; a support rod 133 is located on the side of the hatch 121 facing the crew compartment 110, for example, the support rod 133 is located on the rear side of the hatch 121; the end of the support rod 133 is rotatably connected to the hatch 121, and the enclosed shell 132 is rotatably connected to the cabin body. Thus, by rotating relative to the cabin body on the side of the hatch 121 away from the crew compartment 110, the hatch 121 can rotate as a whole to an attitude where the far side is lower and the near side is higher relative to the crew compartment 110, for example, rotating to... Figure 4 The front side is low and the rear side is high, so as to avoid the edge of the hatch 121 cutting pedestrians and other moving objects in the event of a collision.

[0067] Specifically, refer to Figure 3 and Figure 4 The hatch 121 may have a first buckle 141 on the side away from the crew compartment 110, and the hatch body may have a first lock body 151 on the side away from the crew compartment 110; for example Figure 3 , Figure 4 A first latching ring 141 is provided on the front side of the hatch 121, and a first lock body 151 is provided on the front side of the hull. The first lock body 151 includes a first movable locking section, which extends into the first latching ring 141 to allow the hatch 121 to rotate relative to the first movable locking section. The first movable locking section can be understood as the lock cylinder of the first lock body 151, which can take the form of a rod or the like. The first movable locking section can perform locking and unlocking functions with the first latching ring 141 by extending and retracting, and the first movable locking section can also perform locking and unlocking functions with the first latching ring 141 by rotating to extend and retract.

[0068] In this embodiment, during collision protection, locking can be achieved through the first movable locking section and the first buckle 141. The hatch 121 can rotate around the first movable locking section via the first buckle 141, so that the other end of the hatch 121 can be supported by the support rod 133 to a set height, for example, forming... Figure 4The attitude of the vehicle is such that, without the need for collision protection, it can be unlocked via the first movable locking segment and the first buckle 141, allowing the operator to easily access the receiving cavity of the receiving compartment 120 from the end away from the passenger compartment 110.

[0069] In some implementations, refer to Figure 1 and Figure 2 The hatch 121 has a second buckle 142 on the side facing the crew compartment 110, and the cabin body has a second lock body 152 on the side facing the crew compartment 110; for example Figure 1 , Figure 2 A second latch 142 is provided on the rear side of the hatch 121, and a second lock body 152 is provided on the rear side of the cabin. The second lock body 152 includes a second movable locking section, which is used to retract from the second latch 142 so that the side of the hatch 121 facing the passenger compartment 110 can move away from the cabin along the height direction of the vehicle 100. The second movable locking section can be understood as the lock cylinder of the second lock body 152, which can take the form of a rod or the like. The second movable locking section can lock and unlock with the second latch 142 by extending and retracting, and the second movable locking section can also lock and unlock with the second latch 142 by rotating to extend and retract.

[0070] In this embodiment, during collision protection, unlocking can be achieved via the second movable locking section and the second buckle 142, and the end of the hatch 121 facing the passenger compartment 110 can be supported by the support rod 133 to a set height, for example forming... Figure 4 The hatch 121 is in a stable position. When collision protection is not required, it can be locked by the second movable locking section and the second buckle 142, thereby forming a stable connection between the end of the hatch 121 facing the crew compartment 110 and the cabin body.

[0071] In some implementations, refer to Figure 3 The support device 130 also includes a linkage mechanism 160, which includes a first linkage 161 and a second linkage 162. The first linkage 161 and the second linkage 162 are respectively disposed on the side of the hatch 121 facing the crew compartment 110, for example, disposed on... Figure 3 The rear side of the first link 161 is rotatably connected to the hatch 121, and the other end of the first link 161 is rotatably connected to the second link 162. The end of the second link 162 away from the first link 161 is rotatably connected to the cabin body. The above-mentioned rotatable connection can be achieved by a pivot.

[0072] In this embodiment, the linkage mechanism 160, which includes the first link 161 and the second link 162, can limit the hatch 121, thereby enabling it to absorb energy more effectively through the deformation of the hatch 121 itself, the fluid compression of the closed cavity, and the adjustment of the supporting force of the support rod 133 on the hatch 121. In the event of a collision, it can absorb collision energy more stably.

[0073] In some implementations, refer to Figure 3 The hatch 121 is provided with an extension arm 122; the end of the extension arm 122 away from the hatch 121 extends along the side facing the crew compartment 110, for example... Figure 3 The extension arm 122 extends from the front upper to the rear lower direction; in addition, the first link 161 is rotatably connected to the end of the extension arm 122 away from the hatch 121, and this rotatable connection can be achieved by a pivot.

[0074] In this embodiment, refer to Figure 4 Since the end of the extension arm 122 away from the hatch 121 extends along the side facing the crew compartment 110, when the first link 161 and the second link 162 are unfolded relative to each other, the extension arm 122 and the first link 161 are more likely to form an angle, which helps to avoid the extension arm 122 and the first link 161 forming a dead point, and helps to avoid the connection between the extension arm 122 and the first link 161 getting stuck and accidentally absorbing collision energy. Thus, it can more concentratedly absorb energy through the deformation of the hatch 121 itself, the fluid compression of the closed cavity, and the support force of the support rod 133 on the hatch 121.

[0075] In other embodiments, reference is made to... Figure 2 and Figure 5 The support device 130 also includes a linkage mechanism 160, which includes a four-bar linkage 163. The virtual quadrilateral formed by the four connection points of the four-bar linkage 163 is shown in the dashed box in the figure. The four-bar linkage 163 connects the hatch 121 and the cabin body respectively. It can be understood that the hatch 121 and the cabin body can be connected by two bars in the four-bar linkage 163 respectively, for example, by a fixed connection. The four-bar linkage 163 is used to move the hatch 121 away from the cabin body along the height direction of the vehicle 100 on the side facing the passenger compartment 110 and the side of the hatch 121 away from the passenger compartment 110. It can be understood that the hatch 121 is moved away from the cabin body as a whole.

[0076] In this embodiment, each part of the hatch 121 is able to move away from components in the receiving cavity of the housing 120, such as the engine in the receiving cavity, so that each part of the hatch 121 can absorb collision energy through its own deformation, increasing the total energy absorption and further reducing collision injuries to pedestrians and other moving objects. Furthermore, the end of the housing 120 away from the passenger compartment 110 (e.g., Figure 1 (e.g., the front end of the canopy 121) at the end of the cabin 110 away from the crew compartment 110. Figure 1 When the front end of the hatch 121 is far from the crew compartment 110, the end of the hatch 121 that is far from the crew compartment 110 (e.g., the front end of the hatch 121) is far from the crew compartment 110. Figure 1 The front end of the device can rise to support pedestrians and other moving objects, absorbing collision energy as early as possible.

[0077] It is understood that this embodiment may also include the aforementioned extension arm 122, the end of which, away from the hatch 121, can be rotatably connected to one of the links of the four-bar linkage 163.

[0078] In some implementations, refer to Figure 1 , Figure 2 and Figure 5 The support device 130 includes two four-bar linkages 163, which are respectively disposed on the side of the hatch 121 facing the passenger compartment 110, for example, on the rear side in the figure; the two four-bar linkages 163 are spaced apart along the width direction of the vehicle 100, for example, spaced apart along the left and right direction in the figure.

[0079] In cases where vehicle 100 may collide with a pedestrian or other moving object, the driver may steer vehicle 100 to a turn. In such cases, refer to... Figure 1 In the above embodiment, the corner position A of the hatch 121 on the side away from the passenger compartment 110 can be used to collide with moving objects; this corner position A is advantageous because it is away from the four-bar linkage 163 and has better deformation capability, so it can easily absorb energy through its own deformation, thereby reducing the collision damage to pedestrians and other moving objects.

[0080] In some embodiments, the processor is used to acquire a first predicted trajectory of the target moving body, a second predicted trajectory of the vehicle 100, and the relative velocity of the vehicle 100 relative to the target moving body. The processor is used to output collision information based on the first predicted trajectory, the second predicted trajectory, and the relative velocity. The first predicted trajectory of the target moving body and the second predicted trajectory of the vehicle 100 can be predicted based on the positions of the target moving body and the vehicle 100 at different times, for example, through straight line fitting or curve fitting. Outputting collision information based on the first predicted trajectory, the second predicted trajectory, and the relative velocity can be understood as follows: when the first and second predicted trajectories have a point of overlap, the relative velocity of the vehicle 100 relative to the target moving body is used to determine whether the target moving body and the vehicle 100 arrive at the point of overlap at the same time, thereby determining whether a collision will occur. This allows for timely protection via the hatch 121 based on the first and second predicted trajectories.

[0081] In some embodiments, the collision detection device further includes a pressure sensor for acquiring the collision force between the target moving body and the vehicle 100. The pressure sensor may be disposed on the surface of the vehicle 100 or connected to a moving part on the surface of the vehicle 100 to detect the collision force. The collision information includes the collision force, and the conveying device 131 is used to adjust the fluid pressure in the enclosed cavity according to the collision force. For example, if the enclosed cavity is divided into a first sub-cavity and a second sub-cavity, at least one of the fluid pressure in the first sub-cavity and the fluid pressure in the second sub-cavity can be changed to adjust the support force on the hatch 121.

[0082] This application also provides a collision protection method, which can be applied to the aforementioned vehicle 100; wherein, referring to Figure 6 The collision protection method includes the following steps:

[0083] Step S100: Obtain object data information on the side of the accommodating compartment 120 facing away from the crew compartment 110, for example, by using the object sensor mentioned above.

[0084] Step S200: Identify the target moving body based on the object data information, which can be understood as identifying whether there are pedestrians, etc.

[0085] Step S300: Obtain the distance between the target moving body and the vehicle 100, for example, by using the object sensor mentioned above;

[0086] Step S400: Obtain the driving speed of the vehicle 100, for example, by means of the speed sensor mentioned above. The driving speed includes at least one of acceleration, velocity, angular velocity, and angular acceleration.

[0087] In step S500, based on the interval distance and driving speed, at least part of the hatch 121 is moved away from the cabin along the height direction of the vehicle 100 and the supporting force on the hatch 121 is adjusted, for example by the aforementioned support device 130.

[0088] In some embodiments, the step of obtaining the distance between the target moving body and the vehicle 100 (step S300 above) includes:

[0089] Obtain the first predicted trajectory of the target moving object, for example, by predicting the position of the target moving object at different times, such as by using methods such as line fitting or curve fitting;

[0090] The step of obtaining the speed of the vehicle 100 (step S400 above) includes:

[0091] The second predicted trajectory of the vehicle 100 is obtained, for example, by predicting the position of the vehicle 100 at different times, such as by straight line fitting, curve fitting, etc.

[0092] The relative speed of the vehicle 100 relative to the target moving body is obtained, for example, by using the speed obtained by the speed sensor described above to form a relative speed.

[0093] The step of moving at least a portion of the hatch 121 away from the cabin along the height direction of the vehicle 100 and adjusting the supporting force on the hatch 121 according to the interval distance and the driving speed (step S500 above) includes:

[0094] Based on the first predicted trajectory, the second predicted trajectory, and the relative velocity, at least a portion of the hatch 121 is moved away from the cabin along the height direction of the vehicle 100, and the supporting force on the hatch 121 is adjusted. This can be understood as follows: when the first predicted trajectory and the second predicted trajectory have a point of overlap, the relative velocity of the vehicle 100 relative to the target moving body is used to determine whether the target moving body and the vehicle 100 arrive at the point of overlap at the same time, thereby determining whether a collision will occur, and thus enabling timely protection through the hatch 121 based on the first predicted trajectory and the second predicted trajectory.

[0095] In some implementations, the collision protection method further includes the following steps:

[0096] The collision force between the target moving body and the vehicle 100 can be obtained, for example, through the pressure sensor mentioned above;

[0097] The supporting force on the hatch 121 is adjusted according to the impact force; for example, when the impact force is large, the supporting force on the hatch 121 can be increased, for example, by increasing the preset pressure difference between the fluid pressure in the first sub-cavity and the fluid pressure in the second sub-cavity; in addition, when the impact force is small, the supporting force on the hatch 121 can be decreased, for example, by decreasing the preset pressure difference between the fluid pressure in the first sub-cavity and the fluid pressure in the second sub-cavity.

[0098] In some embodiments, the above-described collision protection method further includes the following steps:

[0099] Adjusting the distance between at least a portion of the hatch 121 and the cabin body based on the collision information can be understood as adjusting the lifting height of the hatch 121, for example, based on the aforementioned collision force, thereby adjusting the size of the deformation space between the hatch 121 and the cabin body, thus making it suitable for different scenarios, including different spatial conditions of different types of vehicles 100.

[0100] In some embodiments, the above-described collision protection method further includes the following steps:

[0101] Based on the collision information, obtain the collision probability;

[0102] If the collision probability is greater than or equal to a first threshold and less than or equal to a second threshold, a warning message is output, wherein the first threshold is less than the second threshold; wherein, the warning message may include auditory and visual warning signals, thereby reminding the driver to take necessary measures (such as steering, braking, etc.) to eliminate the collision risk;

[0103] If the probability of collision is greater than or equal to the second threshold, at least a portion of the hatch 121 is moved away from the cabin along the height direction of the vehicle 100 and the supporting force on the hatch 121 is adjusted; in addition, if the probability of collision is greater than or equal to the second threshold, the braking system of the vehicle 100 can be pneumatically activated to reduce the driving speed of the vehicle 100.

[0104] In some embodiments, the above-described collision protection method further includes the following steps:

[0105] After acquiring collision information and waiting for a preset time, if no collision occurs, the hatch 121, which is away from the cabin along the height direction of the vehicle 100, is restored to a position close to the cabin. For example, when it is confirmed that the risk of the vehicle 100 hitting a pedestrian or other moving object has been eliminated, the processor can issue a closing command to restore the hatch 121 to a position close to the cabin, thereby preventing the hatch 121 from being raised for a long time and affecting the driver's vision or driving safety. Of course, the hatch 121 can also be manually restored to a position close to the cabin.

[0106] It is understood that since the collision protection method adopts all the technical solutions of all the above embodiments of the vehicle 100, it has at least all the beneficial effects brought about by the technical solutions of the above embodiments, which will not be repeated here.

Any equivalent structural transformations made based on the technical concept of this application and the contents of the specification and drawings of this application, or direct / indirect applications in other related technical fields, are included within the patent protection scope of this application.
