Existing models typically have the pump located in the lower front section of the cabin, but this placement compromises pedestrian protection in the event of a collision. Summary of the Invention

[0003] In order to solve the technical problem that the current active suspension hydraulic pump is not conducive to protecting the legs of pedestrians in a collision accident, the present application provides an active suspension hydraulic pump mounting structure and a vehicle.

[0004] In a first aspect of the present application, an active suspension hydraulic pump mounting structure is provided, comprising:

[0005] front subframe;

[0006] a mounting bracket having a first connecting structure and a second connecting structure, wherein the first connecting structure and the second connecting structure are both connected to the rear cross member of the front subframe;

[0007] a hydraulic pump mounted on the mounting bracket, the hydraulic pump being spaced apart from the battery pack of the vehicle and located below the passenger compartment of the vehicle;

[0008] In which, the first connecting structure is a weakened structure, and the second connecting structure and / or the rear cross beam are provided with a fall-off structure. The height of the weakened structure is higher than the fall-off structure, so that when the hydraulic pump collides with the battery pack, the mounting bracket drives the hydraulic pump to rotate forward and downward relative to the front subframe and then fall off.

[0009] In some embodiments, the weakened structure is a weakened plate, the mounting bracket includes a mounting plate connected to the weakened plate, the mounting plate and the weakened plate are both connected to the rear cross member, the hydraulic pump is mounted on the mounting plate, and the strength of the weakened plate is lower than the strength of the mounting plate;

[0010] The weakened plate has a thickness smaller than that of the mounting plate; and / or, along a direction perpendicular to the head-on collision, the weakened plate has a size smaller than that of the mounting plate.

[0011] In some embodiments, the weakened plate is provided with a first connecting hole and a notch connected to the first connecting hole, and the weakened plate is connected to the rear cross beam via a first screw member extending into the first connecting hole.

[0012] In some embodiments, there are multiple notches, and the multiple notches are spaced around the outer edge of the first connecting hole.

[0013] In some embodiments, the rear crossbeam is provided with a fall-off structure, which is a through-hole and a guide structure arranged in sequence along the collision direction. The crossbeam is provided with a second connecting hole, which is located on the side of the guide structure away from the through-hole. The mounting bracket is connected to the rear crossbeam through a second screw member extending into the second connecting hole, and the minimum width dimension of the cross section of the through-hole is greater than the radial dimension of the head of the second screw member.

[0014] In some embodiments, the guide structure is a guide channel, the guide channel is connected to the second connecting hole and the through hole, and the minimum width of the cross section of the guide channel is smaller than the radial dimension of the rod segment of the second threaded member.

[0015] In some embodiments, two of the second connection holes and two of the drop-out structures are provided, and the two drop-out structures are spaced apart along the width direction of the vehicle.

[0016] In some embodiments, the hydraulic pump is provided with a collision plane, and a collision block is provided at the front end of the battery pack, and the collision block is close to the lower part of the collision plane.

[0017] In some embodiments, the upper end of the mounting plate is connected to the weakened plate and the hydraulic pump, and the lower end of the mounting plate is connected to the rear cross beam and the hydraulic pump. Compared with the upper end of the mounting plate, the lower end of the mounting plate is closer to the head of the vehicle.

[0018] In a second aspect of the present application, a vehicle is provided, comprising:

[0019] The active suspension hydraulic pump mounting structure of the first aspect;

[0020] a battery pack, spaced apart from the hydraulic pump;

[0021] A crew compartment is located above the hydraulic pump.

[0022] According to the active suspension hydraulic pump mounting structure provided in an embodiment of the present application, it includes a front subframe, a mounting bracket and a hydraulic pump. The mounting bracket is provided with a first connecting structure and a second connecting structure. The first connecting structure and the second connecting structure are both connected to the rear cross beam of the front subframe; the hydraulic pump is mounted on the mounting bracket. The hydraulic pump is used to be spaced apart from the battery pack of the vehicle and is located below the passenger compartment of the vehicle.

[0023] In the event of a head-on collision, the front subframe will move rearward, and the hydraulic pump is connected to the front subframe via a mounting bracket, so the hydraulic pump will also move toward the battery pack at the rear and collide. Since the first connection structure is a weakened structure, when the hydraulic pump collides with the battery pack, the weakened structure of the mounting bracket causes the mounting bracket to separate from the rear crossbeam. Since the second connection structure and / or the rear crossbeam is provided with a drop-out structure, and the height of the weakened structure is higher than the drop-out structure, the mounting bracket will rotate around the drop-out structure with the hydraulic pump, and then the mounting bracket will separate from the rear crossbeam, causing the hydraulic pump to fall off. In other words, in the event of a collision between the hydraulic pump and the battery pack, the mounting bracket will first separate from the rear crossbeam at the weakened structure, and then the mounting bracket will rotate forward and downward around the drop-out structure with the hydraulic cylinder and fall off, thereby reducing the risk of the battery pack and the passenger compartment being squeezed.

[0037] In order to enable those skilled in the art to understand the present application more clearly, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative efforts shall fall within the scope of protection of this application.

[0038] The first embodiment of the present application provides an active suspension hydraulic pump mounting structure, so that the hydraulic pump is installed between the battery pack and the front auxiliary vehicle, thereby improving the pedestrian leg protection performance during a collision, and can absorb collision energy and rotate and fall off during a head-on collision, effectively reducing the risk of the battery pack and the passenger compartment being squeezed.

[0039] See also Figure 1 、 Figure 2 、 Figure 3 as well as Figure 4 The active suspension hydraulic pump mounting structure provided in the embodiment of the present application includes a front subframe 100 , a mounting bracket 200 and a hydraulic pump 300 .

[0040] The front subframe 100 is an important load-bearing component of the vehicle chassis system, which can block vibration and noise and improve the driving comfort of the vehicle. Generally speaking, please refer to Figure 2 The front subframe 100 includes a front crossbeam 130, a rear crossbeam 110, and two longitudinal beams 120. The front crossbeam 130 and the rear crossbeam 110 are spaced apart along the length direction of the vehicle body, and the two longitudinal beams 120 are spaced apart along the width direction of the vehicle body. The front crossbeam 130 and the rear crossbeam 110 are both connected to the two longitudinal beams 120 to form the skeleton of the front subframe 100. Figure 2 as well as Figure 3The mounting bracket 200 is provided with a first connecting structure 230 and a second connecting structure 240. Both the first connecting structure 230 and the second connecting structure 240 are connected to the rear cross member 110, forming a two-point connection, thereby achieving a stable connection between the mounting bracket 200 and the rear cross member 110. The hydraulic pump 300 is mounted on the mounting bracket 200, and thus the hydraulic pump 300 is mounted to the rear cross member 110 of the front subframe 100 through the mounting bracket 200. The hydraulic pump 300 is spaced apart from the vehicle's battery pack 400. In other words, the hydraulic pump 300 is located between the front subframe 100 and the battery pack 400, below the vehicle's passenger compartment, and at a considerable distance from pedestrians' legs, thereby improving pedestrian leg protection in the event of a collision.

[0041] In the event of a head-on collision, the front subframe 100 will move rearward, and the hydraulic pump 300, connected to the front subframe 100 via the mounting bracket 200, will therefore also move toward the rear battery pack 400 and collide with it. Because the first connecting structure is a weakened structure 114, when the hydraulic pump 300 collides with the battery pack 400, the weakened structure 114 of the mounting bracket 200 causes the mounting bracket 200 to separate from the rear cross member 110. Because the second connecting structure 240 and / or the rear cross member 110 are provided with a release structure, and the weakened structure 114 is higher than the release structure, the mounting bracket 200 will rotate around the release structure with the hydraulic pump 300, causing the mounting bracket 200 to separate from the rear cross member 110 and the hydraulic pump 300 to fall off. That is to say, when the hydraulic pump 300 collides with the battery pack 400, the mounting bracket 200 is first separated from the rear cross beam 110 at the weakened structure 114, and then the mounting bracket 200 rotates forward and downward around the detachment structure with the hydraulic cylinder and detaches, thereby reducing the risk of the battery pack 400 and the passenger compartment being squeezed.

[0042] Regarding the weakened structure 114 of the mounting bracket 200, when the hydraulic pump 300 collides with the battery pack 400, a portion of the bracket can be separated from the rear cross beam 110, while a portion can be connected to the rear cross beam 110, so that the bracket can drive the hydraulic pump 300 to rotate forward and downward around the unseparated portion. In some embodiments, refer to Figure 4 The weakened structure 114 on the mounting bracket 200 can be a weakened plate 210. The mounting bracket 200 also includes a mounting plate 220 connected to the weakened plate 210. The mounting plate 220 and the weakened plate 210 are both connected to the rear cross beam 110. The hydraulic pump 300 is installed on the mounting plate 220. The strength of the weakened plate 210 is lower than that of the mounting plate 220. The weakened plate 210 is located at the upper part of the mounting bracket 200. Therefore, in the event of a head-on collision, the weakened plate 210 will first deform and break relative to the mounting plate 220, so that the weakened plate 210 will separate from the rear cross beam 110, and then rotate forward and downward under the gravity of the hydraulic pump 300 itself and the reverse force of the battery pack 400 on the hydraulic pump 300.

[0043] In some embodiments, the weakened plate 210 is thinner than the mounting plate 220, so that the weakened plate 210 has lower strength than the mounting plate 220. In other embodiments, the weakened plate 210 is smaller than the mounting plate 220 in the direction perpendicular to the head-on collision, which can also make the weakened plate 210 weaker than the mounting plate 220, causing the weakened plate 210 to deform and fracture first in the event of a head-on collision. In still other embodiments, the weakened plate 210 is made of a different material than the mounting plate 220, for example, the weakened plate 210 is made of Q195 steel and the mounting plate 220 is made of IF steel. This can also make the weakened plate 210 weaker than the mounting plate 220, causing the mounting plate 220 to deform and fracture first in the event of a head-on collision.

[0044] In some embodiments, see Figure 5 as well as Figure 6 The weakened plate 210 is provided with a first connecting hole and a notch 213 connected to the first connecting hole. The notch 213 is close to the battery pack 400. The weakened plate 210 is connected to the rear cross beam 110 by a first screw member 214 extending into the first connecting hole. Therefore, in the event of a collision between the battery pack 400 and the hydraulic pump 300, the design of the notch 213 makes the first connecting hole extremely easy to deform, thereby allowing the first screw member 214 to pass through and lose its fastening effect, and the weakened plate 210 is separated from the rear cross beam 110. During specific implementation, the axial direction of the first threaded member 214 can extend in the vertical direction, and the rear cross beam 110 is provided with a through hole that cooperates with the first threaded member 214. The first threaded member 214 extends into the first connecting hole and the through hole. In the event of a collision, the weakened plate 210 and the rear cross beam 110 will produce relative movement, the weakened plate 210 faces forward, and the rear cross beam 110 faces backward. The notch 213 will also follow the forward movement, and under the action of the first threaded member 214, the weakened plate 210 is torn, so that the weakened plate 210 is separated from the rear cross beam 110, so that there is no fixed point above the hydraulic pump 300, and it rotates forward and downward around the connection point between the mounting plate 220 and the rear cross beam 110 under the combined action of gravity and collision force.

[0045] In some embodiments, see Figure 6 Multiple notches 213 can be provided, for example, two, three, or four. These notches 213 are spaced apart around the outer edge of the first connection hole to ensure that the first threaded member 214 loses its securing function in the event of a collision between the battery pack 400 and the hydraulic pump 300. The number of notches 213 should not be excessive. If so, the connection strength between the weakening plate 210 and the rear cross member 110 may be compromised under normal vehicle driving conditions. The width of the notches 213 should not be too large. If so, the stability of the connection between the weakening plate 210 and the rear cross member 110 may be compromised.

[0046] In some embodiments, see Figure 8 The upper end of the mounting plate 220 is connected to the weakened plate 210 and the hydraulic pump 300, and the lower end of the mounting plate 220 is connected to the rear cross member 110 and the hydraulic pump 300. Compared with the upper end of the mounting plate 220, the lower end of the mounting plate 220 is closer to the head of the vehicle, that is, the mounting plate 220 is tilted to avoid the hydraulic pump 300. In some embodiments, please refer to Figure 8 The weakened plate 210 includes a vertical section 211 and a horizontal section 212 connected to each other. The vertical section 211 is connected to the mounting plate 220 and the hydraulic pump 300 through a connector, such as a threaded connector 225. The horizontal section 212 is connected to the rear crossbeam 110 through a first threaded member 214. The vertical section 211 and the horizontal section 212 are arranged at an angle, such as an L-shape, and the height of the vertical section 211 is higher than the horizontal section 212. In this way, when the battery pack 400 collides with the hydraulic pump 300, the horizontal section 212 is easily deformed and torn locally, so that the first connection structure is separated from the rear crossbeam 110 first, and the second connection structure is separated from the rear crossbeam 110.

[0047] In some embodiments, the plate surface of the weakened plate 210 is parallel to the width direction of the vehicle body. Figure 8 The mounting plate 220 includes a first connecting section 222, a transition section 223 and a second connecting section 224. The first connecting section 222, the hydraulic pump 300 and the vertical section 211 of the weakened plate 210 are connected. The second connecting section 224 is connected to the detachment structure of the rear cross beam 110. The width dimension of the first connecting section 222 (the dimension along the width direction of the vehicle body) is smaller than the width dimension of the second connecting section 224. In other words, the mounting plate 220 adopts a shape that is narrow at the top and wide at the bottom. This can improve the strength of the lower end of the mounting plate 220. During a collision, it is further ensured that the weakened plate 210 first detaches from the rear cross beam 110, and then the mounting plate 220 detaches from the rear cross beam 110.

[0048] Regarding the drop-off structure, in some embodiments, the rear cross beam 110 is provided with a drop-off structure, the second connecting structure is connected to the drop-off structure, and the drop-off structure is a through hole 111 and a guide structure 112 sequentially arranged along the collision direction. Figure 8The rear cross beam 110 is provided with a second connecting hole 115, and the second connecting hole 115 is located on the side of the guide structure 112 away from the through hole 111, that is, the cross beam is provided with a through hole 111, a guide structure 112 and a second connecting hole 115 arranged in sequence along the head-on collision direction, and the mounting bracket 200 is connected to the rear cross beam 110 by a second threaded member 221 extending into the second connecting hole 115. During the head-on collision, the hydraulic pump 300 moves in the opposite direction of the head-on collision under the reverse force of the battery pack 400, and the second threaded member 221 moves from the second connecting hole 115 toward the through hole 111 under the guidance of the guide structure 112. Since the minimum width dimension of the cross section of the through hole 111 is greater than the radial dimension of the head of the second threaded member 221, the second threaded member 221 can be directly separated from the rear cross beam 110 after moving to the through hole 111, so that the hydraulic pump 300 falls off relative to the front subframe 100. In other embodiments, the second connection structure is a drop-out structure. In this case, the arrangement of the second connection hole 115, the guide structure 112, and the through hole 111 is completely opposite to the arrangement of the drop-out structure on the rear cross member 110. The second connection hole 115, the guide structure 112, and the through hole 111 are arranged sequentially along the direction of a head-on collision. In the event of a head-on collision, the hydraulic pump 300 moves forward relative to the subframe, and the drop-out structure also moves forward relative to the subframe, causing the second threaded member 221 to disengage from the through hole 111, thereby separating the hydraulic pump 300 from the front subframe 100. In yet another embodiment, both the rear cross member 110 and the mounting bracket 200 are provided with drop-out structures, which can also achieve separation of the hydraulic pump 300 from the front subframe 100.

[0049] Regarding the setting direction of the second threaded member 221, in some embodiments, please refer to Figure 8 The second threaded member 221 can be optionally arranged perpendicular to the rear crossbeam 110, that is, the second connection hole 115 passes through the rear crossbeam 110 in the height direction. This connection method has a simple structure. In other embodiments, the second threaded member 221 can also be arranged parallel to the rear crossbeam 110, and the bottom of the rear crossbeam 110 is provided with a protrusion with the second connection hole 115, which can also achieve the connection between the mounting bracket 200 and the rear crossbeam 110.

[0050] See the figure, see Figure 8The guide structure 112 may be a guide channel 113. The extension direction of the guide channel 113 is parallel to the axial direction of the second connection hole 115. The guide channel 113 is connected to the second connection hole 115 and the through hole 111. The minimum width of the cross section of the guide channel 113 is smaller than the radial dimension of the rod section of the second screw member 221, so that the mounting bracket 200 is stably connected to the rear crossbeam 110. In the event of a collision, the second screw member 221 can move along the guide channel 113 to the through hole 111 and fall off. In other embodiments, the extension direction of the guide channel 113 is perpendicular to the axial direction of the second connection hole 115. The guide channel 113 is connected to the second connection hole 115 and the through hole 111 to weaken this area, allowing the second screw member 221 to destroy the structure there and move to the through hole 111 and fall off. In some embodiments, when the extension direction of the guide channel 113 is perpendicular to the axial direction of the second connecting hole 115, multiple guide channels 113 can be provided, and the multiple guide channels 113 are spaced apart along the axial direction of the second connecting hole 115 to further weaken the area.

[0051] In some embodiments, there are two second connecting holes 115 and two falling-off structures, and the two falling-off structures are spaced apart along the width direction of the vehicle, that is, the mounting bracket 200 is connected to the rear cross beam 110 through two second screw members 221. The first screw member 214 and the two second screw members 221 enable the mounting bracket 200 to form a three-point connection with the rear cross beam 110, and the connection stability between the mounting bracket 200 and the rear cross beam 110 is high.

[0052] In some embodiments, see Figure 4 The hydraulic pump 300 is provided with a collision plane 310, and a collision block 410 is provided at the front end of the battery pack 400. The collision block 410 is close to the lower part of the collision plane 310 to facilitate the hydraulic pump 300 to rotate forward and downward relative to the rear cross beam 110 and fall off. In other embodiments, the collision block 410 can also be close to the middle of the collision plane 310, which can also achieve the hydraulic pump 300 to rotate forward and downward relative to the rear cross beam 110. In another embodiment, the hydraulic pump 300 is provided with a collision arc surface, and the middle part of the collision arc surface is concave toward itself, which can facilitate the hydraulic pump 300 to rotate forward and downward relative to the rear cross beam 110 and fall off.

[0053] An embodiment of the second aspect of the present application provides a vehicle, comprising a mounting structure of the hydraulic pump 300 according to any embodiment of the first aspect.

[0054] A vehicle having a hydraulic pump 300 installation structure according to any embodiment of the first aspect has its hydraulic pump 300 installed between the battery pack 400 and the front auxiliary vehicle, thereby improving the protection performance of pedestrian legs during a collision, and can absorb collision energy and rotate off during a head-on collision, effectively reducing the risk of the battery pack 400 and the passenger compartment being squeezed.

[0055] The vehicle provided in this application includes a battery pack 400, a passenger compartment, an active suspension, and a hydraulic pump 300 installation structure of any embodiment of the first aspect, wherein the battery pack 400 and the hydraulic pump 300 are spaced apart; the passenger compartment is located above the hydraulic pump 300.

[0056] The motion trajectories of the various structures of the vehicle during a head-on collision provided in this application are as follows:

[0057] In the event of a head-on collision, the collision force is transmitted rearward through the two longitudinal beams 120 of the front subframe 100, and the front subframe 100 moves toward the rear, driving the hydraulic pump 300 to move backward. The hydraulic pump 300 collides with the front end of the battery pack 400. Since the mounting bracket 200 is provided with a weakening structure 114, the mounting bracket 200 will deform to absorb energy, causing the mounting bracket 200 to separate at the position of the first connecting structure (weakened structure 114) above. However, there is still a collision force between the hydraulic pump 300 and the battery pack 400, and the hydraulic pump 300 is Under the action of the collision force and its own gravity, 300 rotates forward and downward around the second connecting structure (detachment structure), so that the second threaded member 221 enters the through hole 111 from the second connecting hole 115 through the guide structure 112, and then the second threaded member 221 separates from the rear cross beam 110. At this time, the hydraulic pump 300 and the mounting bracket 200 fall off. The hydraulic pump 300 and the mounting bracket 200 absorb part of the collision energy during the entire collision process, and provide a buffer gap after falling off, reducing the risk of the battery pack 400 and the passenger compartment being squeezed.

[0058] In the present application, since the weakening structure 114 is on the top and the shedding structure is on the bottom, and both are close to the rear side of the rear cross beam 110, the running path of the hydraulic pump 300 is more certain when a collision occurs, and the accuracy of the downward rotation and shedding is high.

[0059] In this application, unless otherwise expressly specified or limited, a first feature being "above" or "below" a second feature may include the first and second features being in direct contact, or may include the first and second features being in contact not directly but through another feature between them. Moreover, a first feature being "above," "above," and "above" a second feature may include the first feature being directly above or obliquely above the second feature, or may simply mean that the first feature is higher in level than the second feature. A first feature being "below," "below," and "below" a second feature may include the first feature being directly below or obliquely below the second feature, or may simply mean that the first feature is lower in level than the second feature.

[0060] In the description of the present application, it should be understood that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", "clockwise" and "counterclockwise" indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present application.

[0061] In this application, unless otherwise specified or limited, the terms "connect," "fix," etc. should be understood broadly.
