Description

Technical Field

[0001] This utility model relates to the field of electric vehicle technology, specifically, it is a three-in-one fixing bracket assembly for power supply in new energy vehicles. Background Technology

[0002] The three-in-one power supply consists of an on-board charger, a DC-DC converter, and a high-voltage control box, while the three-in-one electric drive consists of a drive motor controller, a drive motor, and a reducer. Both are integrated high-voltage electrical appliances and are currently widely used in new energy vehicles.

[0003] In the existing technology, there are various types of three-in-one power supply fixing brackets. For example, the utility model patent with announcement number CN202557271U discloses an electrical appliance arrangement scheme in the front cabin. An integrated mounting bracket is provided between the left and right longitudinal beams of the front cabin, and the drive motor controller, charger and DC-DC converter and high voltage control box are fixed horizontally on it in sequence. Such integrated mounting brackets are mostly made of profiles, which are large in size and heavy in weight, resulting in high bracket costs. Moreover, the horizontally laid-out arrangement scheme results in low utilization of the horizontal space in the front cabin and is crowded and unsightly. Summary of the Invention

[0004] The purpose of this utility model is to propose a three-in-one fixing bracket assembly for new energy vehicle power supply, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the specific solution of this utility model is as follows:

[0006] A three-in-one power supply mounting bracket assembly for new energy vehicles is composed of two identical split brackets (1). The split brackets (1) have multiple holes on their bodies. The upper mounting surface of the split brackets (1) has a mounting hole (A) for connecting the three-in-one power supply, and the lower mounting surface of the split brackets (1) has a connecting hole (B) for connecting the three-in-one electric drive.

[0007] The two separate brackets (1) are distributed on the left and right sides below the power supply three-in-one (101) and on the left and right sides above the electric drive three-in-one (103).

[0008] A weldable square nut (104) is provided below the mounting hole (A).

[0009] The connecting hole (B) is a round hole and an oblong hole.

[0010] The split bracket (1) has a Z-shaped structure on its side, and the upper and lower mounting surfaces have a height difference.

[0011] The split bracket (1) has a bending structure (105) on its side and a high-voltage wire harness fixing hole (C) on its surface.

[0012] The split bracket (1) has a groove in the middle of the upper mounting surface and a boss in the middle of the lower mounting surface, which are respectively connected to the upper and lower mounting surfaces in a π-shaped structure.

[0013] The beneficial effects of this utility model are as follows: The power supply three-in-one fixing bracket assembly proposed in this utility model is composed of two separate brackets. Compared with the integrated mounting bracket between the left and right longitudinal beams in the front compartment, it is smaller in size and lighter in weight, which is more conducive to the overall vehicle weight reduction. The two separate brackets are universal parts. Rotating one of the separate brackets (1) by 180° can completely overlap with the other separate bracket (1), which can save the cost of developing a set of molds. The power supply three-in-one fixing bracket assembly is fixed by bolts, and the power supply three-in-one is arranged vertically above the electric drive three-in-one, which saves the horizontal arrangement space in the front engine compartment and raises the ground clearance of the power supply three-in-one, increasing the safety of high voltage electricity. The separate bracket (1) has a simple structure, small size, and convenient assembly, which can greatly improve the vehicle installation efficiency. Attached Figure Description

Detailed Implementation

[0019] like Figure 1 As shown, a three-in-one fixed bracket assembly for power supply of new energy vehicles is composed of two identical split brackets (1). One of the split brackets (1) can be rotated 180° to completely overlap with the other split bracket (1). Only one set of molds needs to be developed, and the two split brackets (1) are small in size and light in weight, which can greatly reduce the weight and cost of the whole vehicle.

[0020] like Figure 1 , 2As shown in Figures 3 and 4, the split bracket (1) body is provided with multiple holes. Among them, the upper mounting surface of the split bracket (1) is provided with a mounting hole (A) for connecting the power supply unit, and the lower mounting surface of the split bracket (1) is provided with connecting holes (B) for connecting the electric drive unit. A welded square nut (104) is provided below the mounting hole (A). The bolts on the upper mounting surface of the split bracket (1) are connected to the welded square nut (104), and the bolts on the lower mounting surface of the split bracket (1) are connected to the internal threaded hole of the electric drive unit (103) body to ensure the reliability of the fixation. One of the connecting holes (B) is a round hole and the other is an oblong hole. The combination of the round hole and the oblong hole ensures the assembly accuracy of the power supply unit (101) and the two split brackets (1).

[0021] like Figure 1 As shown, the two split brackets (1) are distributed on the left and right sides below the power supply three-in-one (101) and on the left and right sides above the electric drive three-in-one (103), realizing the vertical arrangement of the power supply three-in-one (101) and the electric drive three-in-one (104), reducing the horizontal arrangement space in the front engine compartment and raising the ground clearance of the power supply three-in-one (101), thus increasing the safety of high voltage electricity.

[0022] like Figure 1 , 2 As shown in Figure 4, the Z-shaped structure on the side of the split bracket (1) can increase the strength of the bracket, and the height difference between the upper and lower mounting surfaces can ensure the heat dissipation and ventilation area below the power supply unit.

[0023] like Figure 1 , 2 As shown in Figure 3, the split bracket (1) has a bending structure (105) on its side and a high-voltage wire harness fixing hole (C) on its surface. The high-voltage wire harness (102) can be fixed to the bending structure (105) by wire harness clips to ensure the reliability and aesthetics of the high-voltage wire harness arrangement.

[0024] like Figure 1 As shown, the upper mounting surface of the split bracket (1) has a groove in the middle, and the lower mounting surface has a boss in the middle, forming a π-shaped structure with the upper and lower mounting surfaces respectively, which is used to enhance the overall bearing strength of the power supply three-in-one fixing bracket assembly.
