Description

Technical Field

[0002] The front subframe is an important part of the chassis system. As a modular integrated unit, the front subframe connects important parts such as the suspension, steering gear, and suspension. It is usually arranged under the front longitudinal beam. The front subframe can improve the strength and rigidity of the vehicle body, reduce the vibration and noise generated by the suspension system and powertrain, and absorb a certain amount of energy during a collision, reduce the deformation of the passenger compartment, and thus reduce the degree of injury to the occupants. Especially in recent years, under the requirements of new energy, the front subframe needs to integrate more functions and structures. For example, while ensuring the mileage benefits brought by lightweight, it also needs to provide battery protection functions, including battery anti-scratch and battery front collision protection, and maintain flexible scalability while expanding the vehicle platform to solve the development cycle and cost issues.

[0003] In order to improve the expansibility and high functional integration of the new energy subframe, structural improvements have been made to the subframe in the prior art. For example, a Chinese patent with publication number CN211943496U discloses a new aluminum full-frame front subframe, which involves the design of a subframe structure, including a front crossbeam, a rear crossbeam, a left longitudinal beam, a right longitudinal beam, and parts such as sleeves, support tubes, and brackets. By providing a chassis-related system installation position on the subframe, the subframe is ensured to be high-strength, lightweight, and has a certain degree of integration. However, no protective structure for the battery pack is provided, and the battery cannot be protected from scratches and collisions at the front end of the battery.

[0004] Therefore, the new energy subframe in the prior art has the problem of not being able to protect the battery from scratches and collisions at the front end of the battery. Utility Model Content

DETAILED DESCRIPTION

[0041] As an important assembly part of new energy vehicles, the safety of batteries is also the top priority of new energy vehicle safety. Since the batteries are installed at the bottom of new energy vehicles, they are more susceptible to collisions and scratches from ground obstacles. Collisions and scratches can easily lead to battery leakage, which can cause battery fires, explosions and other accidents. Therefore, new energy vehicle batteries need necessary protection. Common protection methods generally include adding chassis protection plates to prevent scratches and improving the safety performance of the battery itself to control the hazards of thermal runaway. However, they cannot prevent ground obstacles from invading the battery area and causing collisions and scratches to the battery.

[0042] Therefore, the present application discloses a subframe of a new energy vehicle, and particularly relates to a front subframe of a new energy vehicle. By arranging a ground obstacle blocking device on the front subframe, ground obstacles are prevented from intruding into the battery area, thereby avoiding potential hazards of collision and scratches on the battery caused by ground obstacles.

[0043] In order to make the purpose, technical solution and advantages of the present invention more clear, the implementation mode of the present invention will be further described in detail below with reference to the accompanying drawings.

[0044] The implementation of this embodiment discloses a subframe 100 of a new energy vehicle, see Figure 1The subframe 100 of the new energy vehicle includes a first crossbeam 1 and a second crossbeam 2, the two ends of the first crossbeam 1 in the length direction are respectively connected to a first connecting member 3 and a second connecting member 4, the two ends of the second crossbeam 2 in the length direction are respectively provided with a third connecting member 5 and a fourth connecting member 6, and also includes a first longitudinal beam 7 and a second longitudinal beam 8, the two ends of the first longitudinal beam 7 in the length direction are respectively connected to the first connecting member 3 and the third connecting member 5, the two ends of the second longitudinal beam 8 in the length direction are respectively connected to the second connecting member 4 and the fourth connecting member 6; wherein the first longitudinal beam 7 and the second longitudinal beam 8 extend in parallel along the X direction, and the first crossbeam 1 and the second crossbeam 8 extend in parallel along the X direction. 2 extends in parallel along the Y direction, and further includes a third crossbeam 9, the third crossbeam 9 is arranged between the first crossbeam 1 and the second crossbeam 2, and is closer to the side of the second crossbeam 2, and both ends of the third crossbeam 9 in the length direction are respectively connected to the first longitudinal beam 7 and the second longitudinal beam 8; and when looking from one side of the second crossbeam 2 along the X direction toward the third crossbeam 9, the lower end surface of the third crossbeam 9 protrudes downward in the Z direction from the plane where the lower end surface of the second crossbeam 2 is located, the Z direction is the vehicle height direction in the vehicle coordinate system, the X direction is the vehicle length direction in the vehicle coordinate system, and the Y direction is the vehicle width direction in the vehicle coordinate system.

[0045] Specifically, in this embodiment, see Figure 2 as well as Figure 3 , the lower end face of the third cross beam 9 protrudes downward in the Z direction from the plane where the lower end face of the second cross beam 2 is located, that is, there is a height difference H between the lower end face of the third cross beam 9 and the lower end face of the second cross beam 2, and the lower end face of the third cross beam 9 is closer to the ground, wherein the setting range of the height difference H is 30mm to 45mm, and the specific setting value of the height difference H can be adjusted by the designer according to the vehicle type, the passability and the degree of protection of the battery, for example, it can be 40mm, 35mm, 30mm, etc., and this embodiment does not make the only limitation. As a preferred embodiment of this embodiment, preferably, the height difference H is selected to be 39mm. At this time, if the height of the second cross beam 2 from the ground is 300mm, the height of the third cross beam 9 from the ground is 261mm. It should also be noted that the height of the lower end face of the battery is higher than the height of the lower end face of the third cross beam 9 in the Z direction.

[0046] Furthermore, the subframe 100 of the new energy vehicle disclosed in the present embodiment is explained by taking the height difference H between the lower end surface of the third cross beam 9 and the lower end surface of the second cross beam 2 as 40 mm, the ground clearance of the second cross beam 2 as 300 mm, and the ground clearance of the third cross beam 9 as 260 mm as an example. When the vehicle is in a driving state, if there is an obstacle on the ground, the height of the obstacle is less than 260 mm, for example, 200 mm. At this time, the height of the obstacle is less than the ground clearance of the third cross beam 9, so the vehicle passes the obstacle smoothly; when the height of the obstacle is greater than 260 mm, for example, 270 mm, the height of the obstacle is greater than the ground clearance of the third cross beam 9. When the new energy vehicle travels in front of the obstacle, the third cross beam 9 blocks the obstacle, thereby preventing the obstacle from continuing to move in the direction of the rear battery, and avoiding the obstacle from colliding and scratching the battery.

[0047] Next, the specific structure of the subframe 100 of the new energy vehicle is explained:

[0048] The embodiment of the utility model also discloses a subframe 100 of a new energy vehicle, see Figure 1 The subframe 100 of the new energy vehicle also includes a first reinforcement 10 and a second reinforcement 11; wherein the first reinforcement 10 is connected between the adjacent ends of the third cross beam 9 and the first longitudinal beam 7, and one end of the first reinforcement 10 is connected to a position of one side end of the third cross beam 9 close to the first longitudinal beam 7, and the other end is connected to a position of a corresponding end of the first longitudinal beam 7 close to the third cross beam 9; the second reinforcement 11 is connected between the adjacent ends of the third cross beam 9 and the second longitudinal beam 8, and one end of the second reinforcement 11 is connected to a position of one side end of the third cross beam 9 close to the second longitudinal beam 8, and the other end is connected to a position of a corresponding end of the second longitudinal beam 8 close to the third cross beam 9.

[0049] Preferably, the first reinforcement members 10 and the second reinforcement members 11 are symmetrically distributed along the Y direction.

[0050] With the above-mentioned arrangement, the first reinforcement 10 supports the third cross beam 9 through the first longitudinal beam 7, and the second reinforcement 11 supports the third cross beam 9 through the second longitudinal beam 8, so that the third cross beam 9 has strong impact resistance. When the third cross beam 9 is hit by a high-speed impact from a ground obstacle, the structural stability of the third cross beam 9 itself and the connection stability between the first longitudinal beam 7 and the second longitudinal beam 8 are ensured, thereby ensuring the anti-collision and anti-scratch performance of the third cross beam 9 for the battery when subjected to a large impact. It should be noted that the arrangement of the first reinforcement 10 and the second reinforcement 11 can increase the overall strength and overall stiffness of the subframe 100.

[0051] Further, see Figure 1The first cross beam 1, the second cross beam 2, the third cross beam 9, the first longitudinal beam 7, and the second longitudinal beam 8 all include a beam body with a cross-sectional shape of a square tube; wherein the first connecting member 3 is provided with a connecting port 12 for respectively matching with the adjacent ends of the first longitudinal beam 7 and the first cross beam 1, and the corresponding ends of the first longitudinal beam 7 and the first cross beam 1 are respectively extended into the connecting port 12 and are sleeved and connected with the first connecting member 3; the second connecting member 4 is provided with a connecting port 12 for respectively matching with the adjacent ends of the second longitudinal beam 8 and the first cross beam 1, and the corresponding ends of the second longitudinal beam 8 and the first cross beam 1 are respectively extended into the connecting port 12 and are sleeved and connected with the first connecting member 3. The corresponding ends are respectively extended into the connection ports 12 and are sleeved and connected with the second connecting member 4; the third connecting member 5 is provided with a connection port 12 for respectively adapting to the adjacent ends of the first longitudinal beam 7 and the second cross beam 2, and the corresponding ends of the first longitudinal beam 7 and the second cross beam 2 are respectively extended into the connection port 12 and are sleeved and connected with the third connecting member 5; the fourth connecting member 6 is provided with a connection port 12 for respectively adapting to the adjacent ends of the second longitudinal beam 8 and the second cross beam 2, and the corresponding ends of the second longitudinal beam 8 and the second cross beam 2 are respectively connected to the fourth connecting member 6 through the connection port 12.

[0052] It should be noted that, preferably, the first cross beam 1, the second cross beam 2, the third cross beam 9, the first longitudinal beam 7, and the second longitudinal beam 8 can all adopt square tubes of the same specifications, for example, the cross section is 60mm×50mm, and the square tube plate thickness is 1.8mm; or, under the premise that the strength meets the use requirements, considering the weight reduction, the first cross beam 1 and the third cross beam 9 can also adopt a cross section of 40mm×70mm, and the second cross beam 2, the first longitudinal beam 7, and the second longitudinal beam 8 can all adopt a square tube with a cross section of 60mm×50mm. The specific square tube material selection can be adjusted according to actual needs, and this embodiment does not make a sole limitation on this. It should also be noted that the cross-sectional shape of the first cross beam 1, the second cross beam 2, the third cross beam 9, the first longitudinal beam 7, and the second longitudinal beam 8 can also be selected as a circle, a regular hexagon, etc., and this embodiment does not make a sole limitation on this.

[0053] With the above-mentioned arrangement, preferably, the first cross beam 1, the second cross beam 2, the third cross beam 9, the first longitudinal beam 7, and the second longitudinal beam 8 can all adopt square tubes of the same specifications. By adjusting the length of the square tube, the subframe 100 of the new energy vehicle can be expanded in the X direction and the Y direction without changing the structure of the first connecting member 3, the second connecting member 4, the third connecting member 5, and the fourth connecting member 6, so as to adapt to different wheelbases and motor sizes. For example, the length of the first crossbeam 1, the second crossbeam 2, and the third crossbeam 9 of the subframe 100 of the existing new energy vehicle is 1500mm, and the length of the first longitudinal beam 7 and the second longitudinal beam 8 is 1000mm. If the length requirements of the first crossbeam 1, the second crossbeam 2, and the third crossbeam 9 of the required new subframe are 1350mm, and the length requirements of the first longitudinal beam 7 and the second longitudinal beam 8 are 980mm, then it is only necessary to adjust the length of the first crossbeam 1, the second crossbeam 2, and the third crossbeam 9 from 1500mm to 1350mm, and adjust the length of the first longitudinal beam 7 and the second longitudinal beam 8 from 1000mm to 980mm. The specific adjustment method can be cutting adjustment, and you can also refer to Figure 4 , the depth of the square tube extending into the first connecting member 3, the second connecting member 4, the third connecting member 5 and the fourth connecting member 6 can be adjusted, and there is no need to redesign and develop the sub-frame, so that the sub-frame has flexible size expansion performance to adapt to different wheelbases and motor sizes. At the same time, the use of square tubes with uniform specifications can reduce the overall mold investment, shorten the welding length of the sub-frame 100 of the new energy vehicle, reduce the welding process and thus reduce the welding cost.

[0065] The subframe is also provided with a stabilizer bar 29, which is fixed to the top surfaces of the first longitudinal beam 7 and the second longitudinal beam 8 through a first clamp 27 and a second clamp 28. It should be noted that, in order to facilitate the installation of the stabilizer bar 29 on the top surfaces of the first longitudinal beam 7 and the second longitudinal beam 8, the width of the top surfaces of the first longitudinal beam 7 and the second longitudinal beam 8 is preferably 60 mm, and the specific setting width can be adjusted according to the installation requirements, for example, it can be 58 mm, 62 mm, etc., and this embodiment does not make a sole limitation on this.

[0066] With the above-mentioned arrangement, the subframe 100 of the new energy vehicle is integrated with a first clamp 27 and a second clamp 28 for installing the stabilizer bar 29, so that the stabilizer bar 29 can be directly installed on the top surface of the first longitudinal beam 7 and the second longitudinal beam 8, reducing the number of stamping parts and welding processes required for installing the stabilizer bar 29, further reducing costs.

[0067] The implementation of this embodiment also discloses a subframe 100 of a new energy vehicle, see Figure 1The subframe 100 is provided with a first self-positioning sleeve 33 and a second self-positioning sleeve 34, the first self-positioning sleeve 33 is fixedly provided on the third connecting member 5, the second self-positioning sleeve 34 is fixedly provided on the fourth connecting member 6, the first self-positioning sleeve 33 and the second self-positioning sleeve 34 have through holes extending along the Z direction, and the first self-positioning sleeve 33 and the second self-positioning sleeve 34 are used to be adapted and fixedly connected with the vehicle body self-positioning fixing member 30. The subframe 100 also includes a first mounting sleeve 31 and a second mounting sleeve 32, the first mounting sleeve 31 is fixedly provided on the first connecting member 3, the second mounting sleeve 32 is fixedly provided on the second connecting member 4, and the first mounting sleeve 31 and the second mounting sleeve 32 also have through holes extending along the Z direction.

[0068] It should be noted that, in the present embodiment, the first self-positioning sleeve 33, the second self-positioning sleeve 34 and the first installation sleeve 31 and the second installation sleeve 32 are two sleeves with different structures and functions, wherein the first self-positioning sleeve 33 and the second self-positioning sleeve 34 are used to connect with the vehicle body self-positioning fixing member 30 and to perform accurate positioning and installation to play a self-positioning role, and the first self-positioning sleeve 33 and the second self-positioning sleeve 34 can play a positioning role of two pins on one side, and the vehicle body self-positioning fixing member 30 is arranged on the vehicle chassis, and the vehicle body self-positioning fixing member 30 can be a common vehicle body self-positioning stud pin, vehicle body self-positioning bolt, vehicle body self-positioning stud or other self-positioning pin shaft, etc., which is used to fix and position the vehicle chassis and the subframe to ensure the installation precision and accuracy of the subframe. The first mounting sleeve 31 and the second mounting sleeve 32 are two mounting sleeves. The first mounting sleeve 31 and the second mounting sleeve 32 are only mounting sleeves from the subframe to the vehicle body and do not play a positioning role. They are used to improve the connection strength between the subframe and the vehicle chassis and can absorb the fitting tolerance between the subframe and the vehicle chassis during the assembly process.
