Detailed Implementation

[0048] To make the technical problems, technical solutions, and beneficial effects solved by this application clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0049] In related technologies, the inner panel of the engine hood is typically designed with numerous weakened structural ribs and openings to ensure that the strength and rigidity of the engine hood are within a suitable range, preventing serious pedestrian injury in a collision caused by an engine hood structure with excessive strength and rigidity. In the case of a vehicle-pedestrian collision, the aforementioned engine hood can meet pedestrian protection requirements, but in other pressure or impact conditions, such as when a person is sitting or lying on the engine hood... Figure 1 The image shows people standing on the engine hood and stepping on it. Figure 2 In situations such as when a person is standing on the engine hood to take a photo, the aforementioned engine hood is prone to deformation. To solve the above problem, embodiments of this application provide an engine hood structure and a vehicle, which are described in detail below.

[0050] Referring to Figure 3 and Figure 4 The engine hood structure provided by the embodiments of the present application comprises an engine hood 1 and a support 2 movably arranged in the engine compartment through a movement mechanism, the support 2 has a supporting position and a retracted position; in the supporting position, the support 2 is attached to the inner side of the engine hood 1 to support the engine hood 1, and in the retracted position, the engine hood 1 and the support 2 are spaced apart along the thickness direction of the engine hood 1.

[0051] The engine hood structure is applied to a vehicle. The engine hood 1 comprises an engine hood outer plate 11 and an engine hood inner plate 12, the engine hood inner plate 12 is connected to the inner side of the engine hood outer plate 11. In the supporting position, the support 2 is specifically attached to the engine hood inner plate 12. When the support 2 is in the retracted position, the support 2 is hidden below the engine hood 1 and does not affect the appearance of the front end of the vehicle. When the support 2 is in the retracted position, the distance between the engine hood 1 and the support 2 along the thickness direction of the engine hood 1 can be set according to actual requirements, for example, it can be set to 10-50 mm.

[0052] The movement mechanism is arranged in the engine compartment and can be designed according to the engine compartment arrangement and the shape of the support 2. The movement mechanism can be a pure mechanical structure or a structure comprising a driving member. The movement mechanism can comprise a four-bar linkage mechanism, a gas spring strut mechanism, a rack and pinion mechanism, a scissor-type lifting mechanism, etc. The driving member can be a motor, a gas cylinder, a hydraulic cylinder, etc. The retracted position is below the supporting position. The movement form of the support 2 between the supporting position and the retracted position can be lifting or a composite movement comprising lifting, moving, rotating, etc.

[0053] Referring to Figure 14 , P1 is the supporting position of the support 2, and P2 is the retracted position of the support 2. The height, position along the length direction of the vehicle, and angle with the horizontal plane of the support 2 in the supporting position all depend on the engine hood inner plate 12. The height, position along the length direction of the vehicle, and angle with the horizontal plane of the support 2 in the retracted position depend on the shape of the support 2, the engine compartment arrangement, and other factors. Preferably, the height, position along the length direction of the vehicle, and angle with the horizontal plane of the support 2 in the retracted position are different from those in the supporting position.

[0054] The movement form of the support 2 between the supporting position and the retracted position is preferably a composite movement. The movement mechanism preferably comprises a four-bar linkage mechanism and a driving member, the driving member is connected to the four-bar linkage mechanism, the four-bar linkage mechanism is connected to the support 2, and the driving member is a motor. When the driving member operates, it drives the four-bar linkage mechanism to move, and the movement of the four-bar linkage mechanism drives the support 2 to move, so as to switch the support 2 between the supporting position and the retracted position.

[0055] The operation of the driving member in the movement mechanism can be actively controlled according to the state of the vehicle, so as to actively adjust the position of the support member 2. As an example, during the driving of the vehicle, for example, during the driving above a certain speed, the support member 2 is placed in the retracted position, so as to avoid the support member 2 affecting the pedestrian protection performance of the vehicle in a collision. When the vehicle is powered off or stops driving, the driving member is controlled to operate, and the support member 2 is driven to move from the retracted position to the supporting position, and the support member 2 in the supporting position provides sufficient support for the engine cover to meet the sitting, lying, standing or stepping requirements of personnel of a certain weight on the engine cover 1.

[0056] When the support member 2 is in the supporting position, the active safety system such as the ADAS (Advanced Driver Assistance System) of the vehicle can continuously monitor the situation of the VRU (Vulnerable Road User) such as the cyclist or pedestrian outside the vehicle, and when the collision risk of the VRU such as the cyclist or pedestrian outside the vehicle with the front end of the vehicle is recognized in advance, the driving member is controlled to operate, and the support member 2 is driven to move from the supporting position to the retracted position, so as to restore the strength of the engine cover 1 and ensure the pedestrian protection performance.

[0057] In the embodiments of the present application, the support member 2 can be switched between the supporting position and the retracted position. During the driving of the vehicle, the support member 2 can be placed in the retracted position, at this time, the engine cover 1 and the support member 2 are spaced apart, and the support member 2 does not provide additional support for the engine cover 1 to meet the pedestrian protection performance in a vehicle collision. When the vehicle is powered off or stops driving, the support member 2 can be placed in the supporting position, at this time, the support member 2 supports the engine cover 1 and provides additional strength for the engine cover 1 to meet a certain bearing weight, thereby enhancing the bearing capacity of the engine cover 1, so that the engine cover 1 is not easily deformed under pressure or impact. In summary, in the embodiments of the present application, the engine cover meets the pedestrian protection performance in the case of a vehicle collision during the driving of the vehicle, and at the same time, the strength and rigidity of the engine cover in other pressure or impact conditions are considered, so that the engine cover 1 is not easily deformed in other pressure or impact conditions.

[0058] When the support member 2 in the supporting position is sat, lies, stands or steps on the engine cover 1 by personnel of a certain weight, the support member 2 can provide sufficient support for the engine cover 1, so that the engine cover 1 will not be deformed due to the sitting, lying, standing or stepping of the personnel, thereby making the vehicle including the engine cover structure available for personnel to sit, lie, stand or step on the engine cover 1 when the support member 2 is in the supporting position, greatly enriching the outdoor playability and entertainment of the vehicle. In summary, the engine cover meets the pedestrian protection performance in the case of a vehicle collision during the driving of the vehicle, and at the same time, the entertainment requirements of personnel for sitting, lying, standing or stepping on the engine cover 1 are considered.

[0059] As another application scenario, in the case that an object falls from a high place and hits the engine hood 1, the engine hood 1 is supported by the support 2 in the supporting position, so that the deformation of the engine hood 1 can be weakened or even avoided.

[0060] In some embodiments, referring to Figures 3-7 , the engine hood 1 comprises an engine hood inner panel 12, the engine hood inner panel 12 comprises a closed inner panel main frame 121 and an inner panel rib portion 122 located in the inner panel main frame 121, the inner panel rib portion 122 comprises a plurality of structural ribs 1221, and a plurality of first weakening openings 1212 are formed in the inner edges of the inner panel main frame 121; in the supporting position, the support 2 is attached to at least part of the inner panel rib portion 122 and at least part of the inner edges of the inner panel main frame 121, or the support 2 is attached to at least part of the inner panel rib portion 122.

[0061] In some embodiments, referring to Figure 7 and Figure 8 , a plurality of second weakening openings 1225 are formed in at least two structural ribs 1221, and the pedestrian protection performance can be improved by the plurality of first weakening openings 1212 and the plurality of second weakening openings 1225. The support 2 comprises a support body 21, specifically, the support body 21 is attached to at least part of the inner panel rib portion 122 and at least part of the inner edges of the inner panel main frame 121, or the support body 21 is attached to at least part of the inner panel rib portion 122. The wall thickness of the support body 21 can be set according to actual requirements, for example, it can be 2mm-3mm. The ratio of the orthogonal projection area of the support body 21 to the orthogonal projection area of the space surrounded by the inner panel main frame 121 in the thickness direction of the engine hood, i.e., the height direction of the vehicle, can be greater than or equal to 30%. The support body 21 is a plate-like structure with a shape similar to a trapezoid, and the support body 21 has four side boundaries 217.

[0062] Preferably, in the supporting position, the support 2 is attached to at least part of the inner panel rib portion 122 and at least part of the inner edges of the inner panel main frame 121. In this embodiment, in the supporting position, the support 2 only needs to support the part of the engine hood inner panel 12 that needs to be strengthened in strength, and the support 2 does not need to support the entire engine hood inner panel 12, thereby facilitating the miniaturization and light weight of the support 2 on the basis of providing sufficient support for the engine hood 1.

[0063] In some embodiments, referring to Figure 4 , Figure 9 , Figure 10 and Figure 11The engine hood 1 further comprises an engine hood outer panel 11, and the inner panel rib portion 122 further comprises a bonding edge 1224 bonded to the engine hood outer panel 11, and the structural rib 1221 protrudes in a direction away from the engine hood outer panel 11; the support member main body 21 comprises a support surface 214 and a support groove 215, the support surface 214 is in abutment with the bonding edge 1224, and the support groove 215 is in engagement with the structural rib 1221.

[0064] The bonding edge 1224 is provided with a glue groove, and the engine hood outer panel 11 and the engine hood inner panel 12 are bonded by glue filled in the glue groove. The number of the support grooves 215 and the number of the support surfaces 214 are preferably multiple, and the support grooves 215 and the support surfaces 214 are preferably arranged alternately along the second direction. The shape and size of the support groove 215 protrude from the shape and size of the structural rib 1221. One support surface 214 can support multiple bonding edges 1224. The second direction is specifically the left-right direction of the vehicle, and the second direction can refer to the direction indicated by the F arrow in Figure 3 、 Figure 4 and Figure 11 . Preferably, the support member main body 21 comprises four support surfaces 214, two of which are triangular, and the other two are trapezoidal.

[0065] The plurality of support grooves 215 comprises at least one middle groove 2151 and two edge half grooves 2152, the two edge half grooves 2152 are located at the two side edges of the support member 2 along the second direction, and the at least one middle groove 2151 is located between the two edge half grooves 2152. The middle groove 2151 is a complete groove structure comprising a bottom wall and two side walls, and the edge half groove 2152 is a half groove structure only comprising a bottom wall and one side wall. The support groove 215 preferably comprises three middle grooves 2151 and two edge half grooves 2152. Each middle groove 2151 is located between two support surfaces 214.

[0066] In the supporting position, the support surface 214 of the support member 2 is in abutment with the bonding edge 1224, and the support groove 215 of the support member 2 is in engagement with the structural rib 1221, which can provide sufficient support for the engine hood 1, thereby increasing the maximum weight that the engine hood 1 can withstand, and improving the support stability of the support member 2 in the supporting position.

[0067] In some embodiments, referring to Figure 5 、 Figure 9 、 Figure 10 and Figure 11 , the bottom wall of the support groove 215 is provided with a first protrusion 211 protruding towards the engine hood inner panel 12, and the structural rib 1221 is provided with a first groove 1222, and in the supporting position, the first protrusion 211 of the support member 2 is in engagement with the first groove 1222.

[0068] The number of the first protrusions 211 can be one or more. When the number of the first protrusions 211 is more than one, the first protrusions 211 are arranged in intervals along a second direction. The second direction can refer to the direction shown by the F arrow in Figure 3 、 Figure 4 and Figure 11 . The first recesses 1222 correspond to the first protrusions 211 one by one, and the shapes of the first recesses 1222 match those of the first protrusions 211.

[0070] In the support position, the first protrusions 211 of the support member 2 are embedded in the first recesses 1222, which can limit the displacement of the support member 2 in the first direction in the support position, further improve the support stability of the support member 2 in the support position, and avoid the displacement of the support member 2 relative to the hood 1 due to external force or vibration.

[0071] In some embodiments, the structural rib 1221 is provided with a second protrusion protruding towards the support member 2, and the support member body 21 has a second recess. In the support position, the second recess of the support member 2 is embedded in the second protrusion.

[0072] In some embodiments, referring to Figure 6 、 Figure 7 、 Figure 8 、 Figure 10 and Figure 11 , the two ends of the support member body 21 along the first direction are respectively provided with a first inclined surface 212 and a second inclined surface 213, the inner edge of the inner plate main frame 121 is provided with a third inclined surface 1211, and the inner plate rib portion 122 is provided with a fourth inclined surface 1223. The first inclined surface 212 is in abutment with the third inclined surface 1211, and the second inclined surface 213 is in abutment with the fourth inclined surface 1223.

[0073] The first direction is specifically the front-rear direction of the vehicle. The first direction can refer to the direction shown by the E arrow in Figure 3 、 Figure 5 、 Figure 6 and Figure 11 . The first inclined surface 212 is located at the front end of the support member 2, and the second inclined surface 213 is located at the rear end of the support member 2. The first inclined surface 212 corresponds to the third inclined surface 1211 one by one, and the second inclined surface 213 corresponds to the fourth inclined surface 1223 one by one.

[0074] In the embodiment, the first inclined surface 212 is attached to the third inclined surface 1211, and the second inclined surface 213 is attached to the fourth inclined surface 1223, so that the positioning of the support 2 in the support position is achieved, the displacement of the support 2 in the support position in the first direction is limited, and the support stability of the support 2 in the support position is further improved, so that the displacement of the support 2 relative to the hood 1 caused by external force or vibration is avoided.

[0075] In some embodiments, referring to Figure 15 , Figure 16 , Figure 12 and Figure 13 , the side of the support body 21 away from the hood 1 is provided with a reinforcing rib 22. The number and structure of the reinforcing rib 22 can be matched according to the strength requirement of the support 2 of the specific vehicle model, and the thickness, height, angle, number, etc. of the reinforcing rib 22 can be optimized. The number of reinforcing ribs 22 can be one, two, three, etc. The number of reinforcing ribs 22 is preferably two. The reinforcing rib 22 can extend in the second direction and span the support body 21. When the number of reinforcing ribs 22 is multiple, the multiple reinforcing ribs 22 can be arranged in the first direction. In the embodiment, the stiffness and strength of the support 2 can be improved by the arrangement of the reinforcing rib 22.

[0076] In some embodiments, the movement mechanism includes a driving member configured to drive the support 2 to move so as to switch the support 2 between the support position and the retracted position.

[0077] The driving member is electrically connected to the controller of the vehicle, and the position of the support 2 can be controlled by controlling the operation of the driving member to move the support 2 from the support position to the retracted position or from the retracted position to the support position. In the embodiment, the support 2 can be automatically switched between the support position and the retracted position by the driving member, without the need for manual adjustment of the position of the support 2. The position of the support 2 can also be accurately controlled by the driving member to ensure the accuracy of the position of the support 2.

[0078] In some embodiments, the material of the support 2 is long glass fiber reinforced plastic, for example, 30% long glass fiber reinforced plastic (LGF30), which is conducive to lightweight on the basis of providing sufficient support for the hood 1. In other embodiments, the material of the support 2 can also be metal, such as steel, aluminum alloy, etc.

[0079] It should be noted that when the support 2 is designed, the wall thickness of the support body 21, the material and size of the support 2, and the number of reinforcing ribs 22 can be flexibly matched and adjusted according to the design strength requirements of each vehicle model to adapt to different sizes, different strengths, and different heights of the hoods of different vehicles, and to be as embedded as possible with the structure of the inner panel 12 of the hood.

[0080] In some embodiments, with reference to Figure 10 and Figure 11 , the support body 21 is provided with mounting holes 216, and fasteners are arranged in the mounting holes 216. The support 2 is detachably connected to the movement mechanism through the fasteners.

[0081] The mounting holes can be circular or waist-shaped. The fasteners can be bolts or screws. The number of the mounting holes 216 can be set according to actual requirements, for example, the number can be 4-8. Preferably, the number of the mounting holes 216 is six, two mounting holes 216 are arranged on the bottom wall of each edge half-groove 2152, and two mounting holes 216 are arranged on the bottom wall of the middle groove 2151. In this embodiment, the support 2 is detachably connected to the movement mechanism through the fasteners, the connection between the support 2 and the movement mechanism is reliable, and the support 2 is convenient to install and detach.

[0082] It should be noted that, according to the protruding structure of the fastener, for example, the head of the bolt, a groove can be arranged at the corresponding position of the inner panel 12 of the engine cover, so that the protruding structure of the fastener is embedded in the groove of the inner panel 12 of the engine cover.

[0083] It should be noted that the above support can be designed in combination with the engine compartment apron, the front spare tank cover plate, or the engine apron, and no new structure is added, which has little effect on the engine compartment layout.

[0084] In some embodiments, with reference to Figure 7 , Figure 15 , Figure 16 and Figure 17 , the engine cover structure further includes an engine cover mounting hinge 3, an engine cover lock body 4, an engine cover lock catch 5, a left upper longitudinal beam 6, and a right upper longitudinal beam 7. The inner panel 12 of the engine cover is bolted to the left upper longitudinal beam 6 through the left engine cover mounting hinge 3 and bolted to the right upper longitudinal beam 7 through the right engine cover mounting hinge 3, to ensure the mounting stability of the rear part of the engine cover 1. The engine cover lock catch 5 is arranged on the engine cover 1, and the engine cover lock body 4 is arranged at the front end of the vehicle body. After the engine cover 1 is closed, the engine cover lock catch 5 is clamped and locked with the engine cover lock body 4, to ensure the mounting stability of the front part of the engine cover 1.

[0085] It should be noted that the engine cover mounting hinge 3, the engine cover lock body 4, the engine cover lock catch 5, the left upper longitudinal beam 6, and the right upper longitudinal beam 7 can be replaced by other structures according to the engine compartment layout, modeling design, and other factors of the actual vehicle model.

[0086] The embodiments of the present application also provide a vehicle including the above engine cover structure. Since the vehicle includes the above engine cover structure, the vehicle also has the beneficial effects of the above engine cover structure, which will not be described here.

[0087] The vehicle can be a sedan, a business car, an off-road vehicle, a sport utility vehicle, etc. The vehicle can be a pure electric vehicle, a fuel vehicle, a hybrid vehicle, etc.

[0088] The vehicle further comprises a controller and a vehicle speed sensor, and the controller is electrically connected with the vehicle speed sensor. The movement mechanism in the engine cover structure comprises a driving member, and the driving member is electrically connected with the controller. By controlling the operation of the driving member, the support member 2 can be controlled to move from the supporting position to the retracted position or from the retracted position to the supporting position.

[0089] Referring to Figure 18 , the control process of the engine cover structure in the vehicle can be:

[0090] After the vehicle is powered on, the vehicle ECU (Electronic Control Unit) detects whether the movement mechanism is normal and whether the support member 2 is located at the supporting position. As the vehicle starts to drive from 0 speed, the speed gradually increases. When the vehicle speed is higher than the support member retraction speed threshold for the first time, the movement mechanism performs a retraction action to move the support member 2 to the retracted position. When the vehicle speed gradually decreases to be lower than the support member lifting speed threshold, the ECU determines the next action according to the subsequent state of the vehicle. If the vehicle stops and powers off, the movement mechanism performs a lifting action. If the vehicle maintains the parking P gear state, and the passenger compartment issues a support member lifting instruction in the form of button control, display screen panel control or voice control, etc., the movement mechanism performs a lifting action. At this time, if the vehicle powers off, the support member 2 remains at the supporting position. If the vehicle starts to drive again and the speed reaches the support member retraction speed threshold, the movement mechanism performs a retraction action.

[0091] After the vehicle is powered on, the active safety system of the vehicle continuously detects the VRU targets such as two-wheeled vehicle riders, pedestrians, etc. outside the vehicle. If the ECU damage prediction algorithm combined with the relative speed between the vehicle and the pedestrian determines that a vehicle-pedestrian collision is about to occur and the damage degree reaches a certain threshold, the ECU issues an instruction, and the movement mechanism performs a retraction action to restore the pedestrian protection performance of the engine cover 1 itself and reduce the damage of the person outside the vehicle in the collision accident.

[0092] When the vehicle is in the parking P gear state or the powered-off state, if the engine cover 1 of the vehicle is unlocked by a person, the movement mechanism performs a retraction action. Subsequently, when the engine cover 1 is closed and locked in place, the movement mechanism performs a lifting action.

[0093] It should be noted that the movement mechanism performs the retracting action, specifically referring to the operation of the driving member of the movement mechanism, driving the support member 2 to move from the supporting position to the retracting position. The movement mechanism performs the lifting action, specifically referring to the operation of the driving member of the movement mechanism, driving the support member 2 to move from the retracting position to the supporting position. The support member retracting speed threshold can be 10-15 km / h, and the support member lifting speed threshold can be 5-10 km / h.

[0094] Before a pedestrian-vehicle collision accident occurs, the active safety recognition system of the vehicle, such as radar, camera, infrared camera, etc., provides a detection signal for the vehicle ECU, and identifies the risk degree of pedestrian-vehicle collision in advance, and actively moves the support member 2 to the retracting position to avoid the collision injury of the person outside the vehicle being aggravated due to the support member 2 being in the supporting position.
