The collapse portion 21 can absorb energy when collapsing, thereby absorbing the load received by the front end of the front longitudinal beam 2, reducing the transmission of collision energy to the front compartment assembly and other components, and improving the stability of the front compartment of the vehicle.
[0055] Optionally, in an embodiment of the present disclosure, the top surface of the front longitudinal beam 2 and / or the bottom surface of the front longitudinal beam 2 and / or the side surface of the front longitudinal beam 2 is provided with a collapse portion 21, the collapse portion 21 is arranged in a strip structure, the collapse portion 21 located on the top surface of the front longitudinal beam 2 and the collapse portion 21 located on the bottom surface of the front longitudinal beam 2 extend along the width direction of the vehicle, and the collapse portion 21 located on the side surface of the front longitudinal beam 2 extends along the height direction of the vehicle. By such arrangement, the collapse portion 21 can collapse in the front-rear direction of the vehicle, which is beneficial to absorbing the energy of the collision.
[0056] It should be noted that the collapse portion 21 can be arranged on the top surface of the front longitudinal beam 2, the bottom surface of the front longitudinal beam 2, or the side surface of the front longitudinal beam 2 according to the energy absorption requirements, for example, the collapse portion 21 can be arranged on one of the top surface of the front longitudinal beam 2, the bottom surface of the front longitudinal beam 2, and the side surface of the front longitudinal beam 2, or two of them, or all of them, which is not limited here.
[0057] The collapse portion 21 is arranged in a strip structure, which can increase the collapse degree of the collapse portion 21 and improve the energy absorption effect.

[0059] Optionally, in an embodiment of the present disclosure, the collapse portion 21 is arranged as a recess or protrusion formed on the beam surface of the front longitudinal beam 2. It can be understood that the beam surface of the front longitudinal beam 2 can be recessed inward to form a recess or protruded outward to form a protrusion.

[0063] The first lap joint 31 is arranged in a top-down stacking manner with the rear end of the component after being connected with the rear end of the component, which can increase the connection area and improve the connection stability. In addition, the front compartment assembly 1 can be used for mounting the power assembly. Since the first lap joint 31 is located above the component, the first lap joint 31 will not interfere with the assembly of the power assembly. The power assembly can be connected with the first lap joint 31 in a top-down manner after being connected with the front compartment assembly 1, which improves the assembly efficiency and the connection stability and can support each other.
[0064] In some examples, the first lap joint 31 can be a plate structure, which is directly arranged on the rear end of the component and then fixed by connecting bolts or welding.
[0065] In order to facilitate the direct connection between the first connecting piece 3 and the front longitudinal beam 2, in an embodiment of the present disclosure, the first connecting piece 3 further comprises a first body 32, which is arranged in a spaced manner. In some examples, the two first bodies 32 are arranged in a spaced manner in the width direction of the vehicle. One end of each first body 32 is provided with a first lap joint 31. One end of one of the first bodies 32 is connected with the side surface of the front longitudinal beam 2, and the other end of the other first body 32 is connected with the top surface of the front longitudinal beam 2. By arranging two first bodies 32 and arranging them in a spaced manner in the width direction of the vehicle, a space is formed between the two first bodies 32, which can support each other in the width direction of the vehicle and improve the reliability and stability of the connection.
[0066] In some examples, the first body 32 extends in the height direction of the vehicle, the first lap joint 31 is connected to the top of the first body 32, and the bottom of the first body 32 is connected with the front longitudinal beam 2. The bottom of the first body 32 is provided with a first connecting edge 33, which can be attached to the front longitudinal beam 2 and can be welded or connected by bolts. It can be understood that the bottom of each of the two first bodies 32 is provided with a first connecting edge 33, which is connected with the top surface and the side surface of the front longitudinal beam 2 respectively, thereby realizing the connection with different positions of the front longitudinal beam 2 and improving the connection area and the connection stability.
[0067] In the width direction of the vehicle, the rear end of the component is provided with a first connecting piece 3 on both sides, and the two first connecting pieces 3 are connected with the two front longitudinal beams 2 respectively.
[0068] Optionally, in an embodiment of the present disclosure, the first body 32 is provided in a plate shape, and the first body 32 is at least partially curved in an arc shape. By being provided in this way, the structural strength of the first body 32 in the height direction of the vehicle is high, the support effect in the height direction of the vehicle can be achieved, and the connection stability and the connection strength are improved. In some examples, the first body 32 is curved in a substantially "C" shape. It should be noted that the "C" shape refers to the shape viewed from the side of the first body 32.
[0069] Optionally, in an embodiment of the present disclosure, the first connecting piece 3 is detachably connected to the rear end of the member. By being provided in this way, the assembly type connection can be achieved, the replacement and maintenance can be performed, and the maintenance cost is reduced.
[0070] Optionally, in another embodiment of the present disclosure, the first connecting piece 3 is detachably connected to the front longitudinal beam 2. By being provided in this way, the assembly type connection can be achieved, the replacement and maintenance can be performed, and the maintenance cost is reduced. Of course, in other embodiments, the two ends of the first connecting piece 3 can be detachably connected to the rear end of the member and the front longitudinal beam 2, respectively, and can be provided according to the design of the actual vehicle model, which is not limited here.
[0071] Optionally, in another embodiment of the present disclosure, the two ends of the first connecting piece 3 can be respectively welded and fixed to the rear end of the member and the front longitudinal beam 2.
[0072] Optionally, in an embodiment of the present disclosure, the vehicle front compartment structure further comprises a second connecting piece 4 and a front wheel cover assembly 5, the front lower arm 11 is connected to the second connecting piece 4, and the end of the second connecting piece 4 away from the front lower arm 11 is connected to the front wheel cover assembly 5.
[0073] The front lower arm 11 and the front wheel cover assembly 5 are connected together through the second connecting piece 4, so that they form an integral whole and support each other, and the front compartment assembly 1 and the front wheel cover assembly 5 can bear forces together. Since the front wheel cover assembly 5 is close to the tire, the tire will rotate and jump up and down during the driving of the vehicle, so the front wheel cover assembly 5 bears more and more complex loads, and can bear forces in multiple directions. Therefore, the front wheel cover assembly 5 has the problem of concentrated stress, and after the front lower arm 11 is connected to the front wheel cover assembly 5 through the second connecting piece 4, the front wheel cover assembly 5 can be supported and dispersed, so that the dynamic modal of the front wheel cover assembly 5 is improved, and the stability of the entire front compartment is improved.
[0074] In addition, when a collision occurs, the front compartment assembly 1 and the front wheel cover assembly 5 serve as a force transmission path and can together absorb and disperse the collision energy, thereby improving the stability and safety of the front compartment. In particular, when the front wheel of the vehicle is subjected to a collision load, the front lower arm 11 can effectively support the front wheel cover assembly 5 to achieve absorption and dispersion of the collision energy.
[0075] In the width direction of the vehicle, the second connecting piece 4 is arranged on both sides of the front lower arm 11, and the two second connecting pieces 4 are respectively connected to the two front wheel cover assemblies 5.
[0076] To improve the connection stability of the second connecting piece 4 and the front lower arm 11, optionally, in an embodiment of the present disclosure, the second connecting piece 4 comprises a second lap joint portion 41, and the second lap joint portion 41 is connected to the front lower arm 11. In the height direction of the vehicle, the second lap joint portion 41 is arranged above the front lower arm 11.
[0077] After the second lap joint portion 41 is connected to the front lower arm 11, the second lap joint portion 41 and the front lower arm 11 are arranged in a stacked form, which can increase the connection area and improve the connection stability. In addition, the front compartment assembly 1 can be used to mount a power assembly, and the power assembly can be connected to the connection position of the front lower arm 11 and the second lap joint portion 41. Since the second lap joint portion 41 is located above the front lower arm 11, the second lap joint portion 41 will not interfere with the assembly of the power assembly. The power assembly can be connected to the front compartment assembly 1 from bottom to top, which improves the assembly efficiency and improves the connection stability, and the power assembly and the front compartment assembly 1 can support each other.
[0078] In some examples, the second lap joint portion 41 can be a plate structure, and the second lap joint portion 41 is directly arranged on the front lower arm 11 and then connected and fixed by connecting bolts or fixed by welding. In other examples, the second lap joint portion 41 can be a clamping groove structure, and the front lower arm 11 is clamped into the second lap joint portion 41, so that the second lap joint portion 41 is arranged on the front lower arm 11.
[0079] To facilitate the connection of the second connecting piece 4 and the front wheel cover assembly 5, optionally, in an embodiment of the present disclosure, the second connecting piece 4 further comprises a second body 42, and the second lap joint portion 41 is connected to one end of the second body 42. The other end of the second body 42 is connected to the front wheel cover assembly 5. The second body 42 can extend towards the front wheel cover assembly 5 to achieve connection with the front wheel cover assembly 5.
[0080] In some examples, the second body 42 extends along the width direction of the vehicle, one end of the second body 42 is connected with the second lap joint 41, and the other end of the second body 42 is connected with the front wheel cover assembly 5. The second body 42 is provided with a second connecting edge 43, which can be attached to the front wheel cover assembly 5 and can be welded or bolted with the front wheel cover assembly 5. In some examples, the second connecting edge 43 can be a flange formed on the second body 42.
[0081] Optionally, in an embodiment of the present disclosure, the front wheel cover assembly 5 comprises a front wheel cover side beam 51 connected with the front longitudinal beam 2, and the second connecting piece 4 is connected with the front wheel cover side beam 51. The second connecting edge 43 can be attached to the front wheel cover side beam 51 and welded or bolted.
[0082] The part of the front wheel cover side beam 51 covers the inner wall of the front wheel cover, and a cavity is formed between the front wheel cover side beam 51 and the front wheel cover, which can strengthen the structure. Then, the front wheel cover is close to the front wheel, and the front wheel will rotate and jump up and down during the driving of the vehicle. Therefore, the front wheel cover side beam 51 bears more and more complex loads and may bear forces in multiple directions. Therefore, the front wheel cover side beam 51 has the problem of concentrated stress, and the front wheel cover side beam 51 is connected with the second connecting piece 4 through the front lower arm 11, which can support the front wheel cover side beam 51 and disperse the stress of the front wheel cover side beam 51, thereby improving the dynamic modal of the front wheel cover side beam 51 and the stability of the entire front compartment.
[0083] Then, the front wheel cover side beam 51 is welded and fixed with the top of the front longitudinal beam 2, and the cavity between the front wheel cover side beam 51 and the front wheel cover is in communication with the front longitudinal beam 2. Therefore, after the front wheel cover side beam 51 is connected with the front longitudinal beam 2, the cavity between the front wheel cover side beam 51 and the front wheel cover can support the front longitudinal beam 2, and conversely, the front longitudinal beam 2 can also support the cavity between the front wheel cover side beam 51 and the front wheel cover, so that the front wheel cover side beam 51 and the front longitudinal beam 2 can bear forces together. In addition, the front wheel cover side beam 51 can also be connected with the front compartment side beam 7 to support each other, thereby improving the dynamic modal and stability of the front compartment.
[0084] In addition, the front wheel cover side beam 51 and the front lower arm 11 are connected through the second connecting piece 4, which can also bear forces together. When a collision occurs, the front longitudinal beam 2, the front wheel cover side beam 51 and the front lower arm 11 can form a force transmission path, which can absorb and disperse the collision force of the front longitudinal beam 2, and the front longitudinal beam 2 itself also has a rear force transmission path.
[0085] Optionally, in an embodiment of the present disclosure, the two ends of the second connecting member 4 can be fixedly connected or detachably connected with the front cross arm 11 and the front wheel cover side beam 51 respectively, and the specific setting can be performed as required, which is not limited too much here. In some examples, the second connecting member 4 can be fixedly connected with the front wheel cover side beam 51 by welding, and the second connecting member 4 is connected with the front cross arm 11 by bolts, and the two ends of the first connecting member 3 can be connected with the rear end of the component and the front longitudinal beam 2 by bolts respectively. In this way, the assembly positioning can be facilitated, the assembly accuracy can be ensured, the connection performance can be maintained, and the maintenance and replacement can be facilitated.
[0086] In order to improve the mounting stability of the front cross arm 11 and further improve the stability of the front compartment, optionally, in an embodiment of the present disclosure, the vehicle front compartment structure further comprises a third connecting member 9, and the two ends of the third connecting member 9 are connected with the front cross arm 11 and the front longitudinal beam 2 respectively.
[0087] Among them, the third connecting member 9 can be connected with the front cross arm 11 and the front longitudinal beam 2, and the front cross arm 11 is connected with the front wheel cover side beam 51 and the front longitudinal beam 2 through the second connecting member 4. The front cross arm 11 is connected with the front wheel cover side beam 51 and the front longitudinal beam 2 at the same time, so that the front cross arm 11, the front wheel cover side beam 51 and the front longitudinal beam 2 form an integrated structure and support each other.
[0088] Optionally, in an embodiment of the present disclosure, the third connecting member 9 comprises two plate bodies 91, and the two plate bodies 91 are arranged at intervals. One of the plate bodies 91 is connected with the side surface of the front longitudinal beam 2 away from one end of the front cross arm 11, and the other plate body 91 is connected with the top surface of the front longitudinal beam 2 away from one end of the front cross arm 11. By arranging the two plate bodies 91 and arranging them at intervals in the width direction of the vehicle, there is an interval space between the two plate bodies 91, so that a supporting effect in the width direction of the vehicle can be generated, and the reliability and stability of the connection can be improved.
[0089] Among them, in some examples, the plate body 91 extends along the height direction of the vehicle, and the bottom of the plate body 91 is connected with the front longitudinal beam 2.

By such arrangement, the front cross arm 11, the rear cross arm 13 and the two trailing arms 12 do not form a parallelogram structure, but form a triangular structure on one side, so that the stability between the front cross arm 11, the rear cross arm 13 and the two trailing arms 12 can be improved.
[0098] Wherein, one of the longitudinal arms 12 is perpendicular to the front cross arm 11, which means that the longitudinal arm 12 extends in the front-rear direction of the vehicle without skewing.

Since the first connecting piece 3 is a structural connecting device, and there is a certain distance between the rear transverse arm 13 and the front longitudinal beam 2, in order to meet the connection of the rear transverse arm 13 and the front longitudinal beam 2, a certain degree of extension is required. The rear transverse arm 13 can be manufactured by stamping or die casting, and the required length and extension direction can be directly set and directly manufactured integrally. Compared with the structural design of the first connecting piece 3, the cost is lower, and it is more beneficial to production and manufacturing. Therefore, the rear transverse arm 13 is arranged in three sections, namely the first section 131, the second section 132 and the third section 133, which extend in different directions, meet the space limitation requirement between the rear transverse arm 13 and the front longitudinal beam 2, and make the structure of the first connecting piece 3 simple.

[0110] The front transverse arm 11 and the front longitudinal beam 2 are arranged in the height direction of the vehicle in a top-down manner, and the front transverse arm 11 and the front longitudinal beam 2 are not directly connected, so that in the event of a collision, the stress of the front longitudinal beam 2 is transmitted to the front transverse arm 11 through the front wheel cover side beam 51, multi-stage force transmission is realized, and collision force dispersion and multi-stage absorption are realized.
[0111] In some examples, the front cross arm 11 is above the front longitudinal beam 2, and the front cross arm 11 is below the top of the front shock tower 6, so that the front cross arm 11 is between the front longitudinal beam 2 and the top of the front shock tower 6 in the height direction of the vehicle, the middle support effect can be achieved, the front cross arm 11 can support the front wheelhouse side beam 51, and the front wheelhouse side beam 51 can support the front longitudinal beam 2 in the height direction of the vehicle, so that the front longitudinal beam 2 and the front wheelhouse side beam 51 are prevented from being twisted and distorted after a collision, thereby improving the rigidity of the front compartment.
