[0033] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0034] It should be noted that the directions or positional relationships indicated by "front", "rear", "inside", "outside", "up" and "down" in this embodiment are based on the direction of the vehicle itself, where the head of the vehicle represents "front", the rear of the vehicle represents "rear", the top of the vehicle represents "up", and the bottom of the vehicle represents "down", the "inside" side refers to the side facing inside the cab, and the "outside" side refers to the side facing outside the cab.

[0035] In addition, the front and rear direction of the vehicle body defined in the embodiments of the present invention refers to the front and rear direction of the forward direction of the vehicle during driving, the left and right direction of the vehicle body defined refers to the left and right direction of the forward direction of the vehicle during driving, and the up and down direction of the vehicle body defined refers to the up and down direction of the forward direction of the vehicle during driving.

[0036] Please also read Figures 1 to 3 Now, the vehicle front suspension combined bracket provided by the utility model is described. The vehicle front suspension combined bracket comprises a bracket body 1. The bracket body 1 is provided with a suspension limit block mounting position 12 parallel to the up and down direction of the vehicle body, a headlight bracket mounting position 13, and a radiator deflector mounting position 11; the bracket body 1 is also provided with a fixing position 14, which is used to be fixed on the vehicle frame.

[0037] The suspension limit block 3 is part of the front suspension system. The suspension limit block 3 is generally fixed on the suspension bracket, and the suspension bracket is fixed on the vehicle frame. For a specific suspension system, the stiffness of the suspension system is divided into two parts: linear segment stiffness and nonlinear segment stiffness. The linear segment stiffness of the suspension system is mainly determined by the structure of the suspension rubber main spring and the rubber hardness. The nonlinear segment stiffness of the suspension system is determined by the suspension limit structure and the rubber hardness of the suspension limit block 3. The suspension limit structure is jointly determined by the structure of the suspension limit block 3 and the structure of the suspension bracket. It should be noted that the front suspension system is a common structure in the prior art of vehicles, and the suspension limit block 3 is also a common structure of the front suspension system, which will not be repeated here.

[0038] Since the front suspension system needs to bear the force along the up-down direction of the vehicle body, the suspension limit block 3 is fixed on the suspension limit block installation position 12 along the up-down direction of the vehicle body.

[0039] The headlight bracket 4 is mainly used for assembling the headlight of the vehicle. The headlight bracket 4 is generally installed at the rear of the bumper, and the headlight bracket 4 is generally fixed on the vehicle frame.

[0040] The function of the radiator guide plate 5 is to dissipate the heat in the radiator through airflow during the vehicle driving process. The automobile radiator generally refers to a water tank. The radiator guide plate 5 is generally fixed to the vehicle frame through a bracket.

[0041] In the prior art, since the front suspension system, the headlight bracket 4, and the radiator deflector 5 are respectively fixed on the vehicle frame, if the front suspension system and the radiator deflector 5 are respectively fixed by brackets, it will cause many parts in the space of the front suspension part. The vehicle front suspension combined bracket provided by the utility model has a suspension limit block installation position 12, a headlight bracket installation position 13, and a radiator deflector installation position 11 respectively set on the bracket body 1, so that the bracket body 1 can be equipped with the suspension limit block 3 and the radiator deflector 5 at the same time, and the above two component brackets can be integrated into one, reducing the number of parts and reducing costs, meeting the development needs of lightweight vehicles, and also providing an assembly point for the headlight bracket 4, improving the fixing and stability performance of the headlight bracket 4.

[0042] In some embodiments, the bracket body 1 can be used as follows Figure 1 The structure shown, see Figure 1 The bracket body 1 is a triangular structure, and the top surface of the bracket body 1 is perpendicular to the up and down direction of the vehicle body; the suspension limit block mounting position 12 and the radiator guide plate mounting position 11 are respectively arranged on the top surface of the bracket body 1, and the headlight bracket mounting position 13 is arranged on the front end surface of the bracket body 1.

[0043] The bracket body 1 is a triangular structure, which makes it stable and has good supporting performance. Since the bracket body 1 is a triangular structure, the radiator guide plate mounting position 11 is directly set on the top surface of the bracket body 1, which can simplify the structure of the bracket body 1 and facilitate assembly with the radiator guide plate 5.

[0044] In addition, the suspension limit block installation position 12 is perpendicular to the up-down direction of the vehicle body, so that the suspension limit block installation position 12 is arranged on the top surface of the bracket body 1, which is also convenient for assembly with the suspension limit block 3.

[0045] The headlight bracket 4 is generally arranged in front of the front suspension system, so that the headlight bracket installation position 13 is located at the front end surface of the bracket body 1, which can simplify the structure of the headlight bracket 4 and facilitate the assembly of the headlight bracket 4 and the bracket body 1.

[0046] See also Figure 1 On the basis of the above-mentioned embodiment, the bracket body 1 is a right-angled triangle structure, and a weight-reducing cavity 15 is formed at the center of the bracket body 1 .

[0047] The support body 1 is a right-angled triangle structure, which can further optimize its stability performance and facilitate assembly in the front overhang space of the vehicle. In addition, it is easy to design and manufacture, reducing costs. A weight reduction cavity 15 is formed in the center of the support body 1, which can reduce the weight of the support body 1 itself and meet the design requirements of lightweight vehicle. The weight reduction cavity 15 penetrates along the thickness direction of the support body 1.

[0048] Specifically, the bracket body 1 includes a transverse portion, a vertical portion and a diagonal portion. It should be noted that when the bracket body 1 is assembled, its transverse portion extends along the front-rear direction of the vehicle body, so the thickness direction of the bracket body 1 is also the left-right direction of the vehicle body.

[0049] The radiator deflector mounting position 11 and the suspension limit block mounting position 12 are respectively arranged on the top surface of the horizontal part, and the headlight bracket mounting position 13 is arranged on the end surface of the horizontal part. Since no other components need to be installed on the vertical part and the diagonal bracing part of the bracket body 1, in order to further reduce the weight of the bracket body 1, multiple weight reduction grooves can be respectively opened on the vertical part and the diagonal bracing part.

[0050] In some embodiments, the radiator guide plate installation position 11 can be used as follows: Figure 1 The structure shown, see Figure 1 The bottom surface of the horizontal part of the bracket body 1 is provided with a boss 16 protruding downward, and the radiator guide plate mounting position 11 is a first mounting hole opened in the horizontal part of the bracket body 1, and the first mounting hole also passes through the boss 16.

[0051] The radiator guide plate mounting position 11 is a first mounting hole, which is connected to the radiator guide plate 5 by bolts, screws or other fasteners, and the assembly method is simple. In addition, a boss 16 is added to the position where the first mounting hole is set, and the length of the first mounting hole can be increased, that is, the fixing strength of the radiator guide plate 5 and the bracket body 1 is increased.

[0052] Preferably, the radiator guide plate 5 can be fixed at the first mounting hole by an L-shaped bending plate 51. Figure 3 shown.

[0054] The suspension limit block mounting position 12 is a second mounting hole, which is connected to the suspension limit block 3 by bolts, screws or other fasteners, and the assembly method is simple; in addition, the second mounting hole extends downward to the vertical part of the bracket body 1, and the fixing strength of the suspension limit block 3 can be increased with the help of the vertical part of the bracket body 1, thereby further increasing the assembly stability performance of the front suspension system.

[0055] In some embodiments, the headlight bracket mounting position 13 may be configured as follows: Figure 1 The structure shown, see Figure 1The front end of the bracket body 1 has a mounting surface 17 perpendicular to the front-rear direction of the vehicle body, and the headlight bracket mounting position 13 is a third mounting hole opened on the mounting surface 17 .

[0056] Since the headlight bracket 4 is fixed to the front end surface of the bracket body 1, in order to facilitate the assembly of the headlight bracket 4 and the bracket body 1, the front end surface of the bracket body 1 is perpendicular to the front-to-back direction of the vehicle body, and one end of the headlight bracket 4 abuts against the mounting surface 17 along the front-to-back direction of the vehicle body. The headlight bracket mounting position 13 is a third mounting hole, which is connected to the headlight bracket 4 by bolts, screws or other fasteners, and the assembly method is simple.

[0057] See also Figure 1 On the basis of the above embodiment, a avoidance cavity 18 is provided on the bracket body 1 behind the mounting surface 17 , and the avoidance cavity 18 passes through along the thickness direction of the bracket body 1 ; the third mounting hole is connected to the avoidance cavity 18 .

[0058] The avoidance cavity 18 is used to avoid the bolts, screws or other fasteners passing through the third mounting hole, and is used to place nuts that are fastened to the bolts, screws or other fasteners.

[0059] In some embodiments, the above-mentioned vehicle front suspension combined bracket can also be used as follows Figure 1 The structure shown, see Figure 1 The vehicle front suspension combined bracket also includes a fixing seat 19, which is arranged on the bottom surface of the bracket body 1 and extends to the periphery of the bracket body 1; the fixing seat 19 is also provided with a fixing position 14.
