[0032] When combined with the accompanying drawings, in view of the following detailed description, the above - mentioned and other aspects, features and advantages of the present utility model will become more apparent.

[0033] Specific embodiments of the present utility model will be described hereinafter with reference to the accompanying drawings; however, it should be understood that the claimed embodiments are merely examples of the present utility model, which can be implemented in various ways. Well-known and / or repetitive functions and structures are not described in detail to avoid obscuring the present utility model with unnecessary or redundant details. Therefore, the specific structural and functional details claimed herein are not intended to be limiting, but are merely used as a basis and representative basis for the claims to teach those skilled in the art to use the present utility model in substantially any suitable detailed structure in a variety of ways.

[0034] A first embodiment of the present utility model provides a front body structure, as Figures 1 - 4 shown, the front body structure includes a front side beam 1 and side beams 2 disposed on both sides of the front side beam 1. The front side beam 1 is detachably connected between the front ends of the two side beams 2. A hood lock bracket 3 and a heat dissipation system fixing bracket 4 are provided on the front side beam 1. Specifically, the side beam 2 includes a left side beam 21 and a right side beam 22. The rear ends of the left side beam 21 and the right side beam 22 are respectively connected to the front bulkhead. The left side beam 21, the front side beam 1, the right side beam 22 and the front bulkhead form a closed annular structure, which improves the stiffness and crashworthiness of the front engine compartment of the vehicle. In the event of a frontal collision, the closed-loop structure can more effectively disperse and absorb the impact force, reduce the intrusion amount of the occupant compartment, and improve the safety of passengers. The main function of the hood lock is to ensure that the engine hood remains closed during driving and prevent potential hazards caused by accidental opening. The heat dissipation system dissipates heat from the engine and reduces its temperature to ensure the safe operation of the engine. By disposing the hood lock bracket 3 and the heat dissipation system fixing bracket 4 on the front side beam 1, the support strength for the hood lock bracket 3 and the heat dissipation system fixing bracket 4 of the engine is improved.

[0035] The front side beam 1 is detachably connected between the front ends of the two side beams 2, making the inspection and replacement of the heat dissipation system more convenient and fast, reducing the maintenance cost and time. Specifically, bolt mounting holes 6 are provided on the front side beam 1. The fastener passes through the bolt mounting hole 6 from top to bottom or from bottom to top to fix the front side beam 1 and the side beam 2, realizing the up-and-down lapping of the front side beam 1 and the side beam 2, facilitating the installation operation, and avoiding the heat dissipation system of the engine. For example: first install the side beam 2 and the heat dissipation system, and then install the front side beam 1. Exemplarily, the fastener is a bolt.

[0036] Furthermore, a positioning hole 7 is provided on one of the front side beam 1 and the side beam 2, and a positioning post cooperating with the positioning hole 7 is provided on the other. For example, the positioning hole 7 is provided on the front side beam 1, and the positioning post is provided on the side beam 2. When installing the front side beam 1 on the side beam 2, first align the positioning post with the positioning hole 7, and then install the front side beam 1 between the left side beam 21 and the right side beam 22 through the fastener, improving the reliability and installation efficiency of the installation of the front side beam 1 and facilitating the operation.

[0037] In another embodiment, positioning holes 7 are provided on the side beam 2, and positioning posts that cooperate with the positioning holes 7 are provided on the front beam 1. When installing the front beam 1 on the side beam 2, first align the positioning posts with the positioning holes 7, and then install the fasteners.

[0038] Among them, when bolt mounting holes 6 and positioning holes 7 are provided on the front beam 1, the positioning holes 7 are arranged between two adjacent bolt mounting holes 6, which improves the connection reliability between the front beam 1 and the side beam 2. Multiple bolt mounting holes 6 can be provided, and the front beam 1 and the side beam 2 are fixed from multiple directions respectively, increasing multiple mounting points and further improving the connection reliability between the front beam 1 and the side beam 2.

[0039] Since the aluminum structure has a relatively low density but high strength, the hood lock bracket 3 and the radiator system fixing bracket 4 are made of aluminum structure, which is beneficial to reducing the weight of the hood lock bracket 3 and the radiator system fixing bracket 4, achieving the lightweight of the vehicle, and at the same time improving the structural stability and safety while reducing the self-weight of the hood lock bracket 3 and the radiator system fixing bracket 4.

[0040] Since the carbon dioxide shielded welding method has small deformation after welding, high welding quality, and high crack resistance of the weld, the hood lock bracket 3 and the radiator system fixing bracket 4 are respectively welded to the front beam 1 by carbon dioxide shielded welding.

[0041] As Figure 1 and Figure 3 shown, the radiator system fixing bracket 4 is installed at the bottom of the front beam 1, and the hood lock bracket 3 is installed at the side of the front beam 1. The radiator system fixing bracket 4 and the hood lock bracket 3 are respectively arranged at different positions of the front beam 1, and the forces at various parts of the front beam 1 are more uniform, ensuring that the front beam 1 has good collision performance.

[0042] The hood lock bracket 3 has a clamping groove 31 for connecting with the front beam 1. Specifically, the clamping groove 31 is clamped with the front beam 1 up and down and then connected by welding. The setting of the clamping groove 31 improves the convenience of connecting the hood lock bracket 3 with the front beam 1, facilitates the operation, and improves the installation efficiency. In addition, the hood lock bracket 3 can also be connected to the front beam 1 through the clamping groove 31 by other means such as bolt connection or riveting.

[0043] The hood lock bracket 3 has a mesh structure or a honeycomb structure, which is beneficial to reducing the weight of the hood lock bracket 3. Exemplarily, the cross-section of the hood lock bracket 3 is in the shape of a "field".

[0044] In some embodiments, an installation bracket 5 is connected between the front side beam 1 and the side beam 2. Specifically, the installation bracket 5 has a hollow structure, and L-shaped structures are provided on the left and right sides of the bottom of the installation bracket 5. Each L-shaped structure is connected to the top wall and the bottom wall of the side beam 2, increasing the contact area between the installation bracket 5 and the side beam 2. The top of the installation bracket 5 is connected to the front side beam 1, ensuring the connection reliability between the installation bracket 5 and the side beam 2.

[0045] In some embodiments, the front side beam 1 has a hollow structure, which can reduce the weight of the front side beam 1 and achieve the lightweight of the vehicle. Reinforcing ribs are provided inside the front side beam 1, and a plurality of reinforcing ribs are arranged in a cross pattern to improve its own stiffness. Exemplarily, the cross-section of the front side beam 1 is in the shape of a "day", "field", or "rice" character.

[0046] As Figure 4 shown, the side beam 2 is connected to the engine compartment longitudinal beam 9 through a plurality of vertical side beam connection plates 8. The plurality of side beam connection plates 8 are arranged at intervals along the length direction of the side beam 2. Arranging a plurality of side beam connection plates 8 can enhance the vertical stability of the front body structure. The side beam connection plates 8 cooperate with the lower engine compartment longitudinal beam 9 to bear the force and complement each other, that is, the force borne by the upper side beam 2 is transmitted to the lower engine compartment longitudinal beam 9 through the side beam connection plates 8, and the force borne by the lower engine compartment longitudinal beam 9 is transmitted to the upper side beam through the side beam connection plates 8.

[0047] Among them, three side beam connection plates 8 are arranged at intervals along the length direction of the side beam 2, namely the first connection plate 81, the second connection plate 82, and the third connection plate 83. The three side beam connection plates 8 form a stable structure between the side beam 2 and the engine compartment longitudinal beam 9, strengthening the connection force between the engine compartment longitudinal beam 9 and the side beam 2 and improving the overall stiffness. And the three side beam connection plates 8 can disperse the force transmitted from the side beam 2 to the engine compartment longitudinal beam 9.

[0048] Among them, the side beam 2, the first connection plate 81, the second connection plate 82, and the engine compartment longitudinal beam 9 enclose a first closed-loop structure, the side beam 2, the second connection plate 82, the third connection plate 83, and the engine compartment longitudinal beam 9 enclose a second closed-loop structure, and the side beam 2, the first connection plate 81, and the third connection plate 83 enclose a third closed-loop structure, realizing a multi-path full closed-loop between the side beam 2 and the engine compartment longitudinal beam 9 and improving the stiffness of the front engine compartment of the vehicle.

[0049] In addition, a fourth connecting plate 84 is provided at the front of the vehicle body. The two ends of the fourth connecting plate 84 are respectively connected to the side beam 2 and the engine compartment longitudinal beam 9. The fourth connecting plate 84 is butted against the first connecting plate 81 to form a reinforcing cavity 85, further improving the strength of the front structure of the vehicle body. The second connecting plate 82 and the third connecting plate 83 are arranged in the middle and rear parts of the side beam 2. To avoid the engine and the shock tower, one end of each of the second connecting plate 82 and the third connecting plate 83 is connected to the inner side of the side beam 2, and the other end of each of the second connecting plate 82 and the third connecting plate 83 is connected to the outer side of the engine compartment longitudinal beam 9. However, the first connecting plate 81 and the fourth connecting plate 84 are located at the front end of the side beam 2 and do not need to avoid the engine, and the first connecting plate 81 and the fourth connecting plate 84 can extend along the vehicle width direction.

[0050] The side beam connecting plate 8 is an aluminum structural member. That is, the first connecting plate 81, the second connecting plate 82, the third connecting plate 83, and the fourth connecting plate 84 can be set as extruded aluminum parts or aluminum stamping parts, and they are integrally formed respectively, which can ensure that they have relatively high strength. Since the density of aluminum profiles is relatively low but the strength is relatively high, using aluminum structural members is beneficial to the weight of the front structure of the vehicle body, and at the same time, the structural stability and safety of the front structure of the vehicle body can be ensured.

[0051] A shock tower is installed at the side beam 2. The shock tower has at least two legs. One end of the leg is connected to the shock tower, and the other end of the leg is connected to the engine compartment longitudinal beam 9. Among them, the installation position of the leg needs to avoid the installation positions of the first connecting plate 81, the second connecting plate 82, the third connecting plate 83, and the fourth connecting plate 84. The leg can jointly with the first connecting plate 81, the second connecting plate 82, the third connecting plate 83, and the fourth connecting plate 84 achieve the effect of strengthening the connection force between the engine compartment longitudinal beam 9 and the side beam 2 and improving the overall stiffness.

[0052] This front structure of the vehicle body has good versatility and can be widely applied to different vehicle models, especially vehicle models that pay attention to safety performance and maintenance convenience.
