Devices such as the electric motor, speed reducer, battery pack, and air-conditioning compressor in an electric vehicle are all welded and fixed on the front engine compartment crossbeam, using the front engine compartment crossbeam as the main supporting device. However, devices such as a vacuum booster pump and a charger are relatively far from the front engine compartment crossbeam.

[0003] For example, the automotive power battery bracket assembly disclosed in the publication number CN218616206U includes: a bracket assembly main body; a pressure-bearing mechanism arranged on the bracket assembly main body, and the pressure-bearing mechanism is used to descend under pressure; a pushing component arranged on one side of the pressure-bearing mechanism, and the pushing component is used to extrude the battery. When reinstalling the automotive battery in the utility model, first place the automotive battery on the bracket assembly main body, and then fix the binding strip to the battery through bolts. As the binding strip is tightened, it can squeeze the pressure-bearing mechanism downward, and at the same time, the pushing component is pushed out by the descent of the pressure-bearing mechanism, so as to fill the gaps between the battery indentations through the pushing component and extrude the battery.

[0004] However, in the prior art, in the actual application of the current traditional automotive power bracket, due to defects in structural design, such as improper treatment of stress concentration points and unreasonable arrangement of reinforcing ribs, it will increase the stress concentration of the bracket when bearing loads, thereby accelerating fatigue failure and affecting the strength and stability of the bracket.

[0013] Compared with the prior art, the advantages and positive effects of the present utility model are as follows:

[0014] The present utility model strengthens the automotive power bracket by providing an auxiliary support assembly.

[0021] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present utility model.

[0022] Please refer to Figures 1 - 4 , the present utility model provides a technical solution: a vehicle power bracket assembly, including a bracket main body. There are two bracket main bodies, and the two bracket main bodies are fixedly connected by high-strength bolts and a plurality of auxiliary support components. The auxiliary support components include reinforcing beams. A plurality of equally spaced support plates are fixedly connected to the inner bottom wall of each reinforcing beam. A prestressed bolt is fixedly connected to the upper surface of each support plate. A nut is threadedly connected to the surface of each prestressed bolt. A damping block is movably connected to the upper surface of the nut, and the top end of the damping block abuts against the inner top wall of the reinforcing beam.

[0023] As Figures 1 - 4 shown, the two bracket main bodies are fixedly connected by a mounting seat on the outside of the auxiliary support components. Cross frames are symmetrically and fixedly connected to both sides of the lower surfaces of the two bracket main bodies. Two groups of first assembly seats are fixedly connected to the upper surface of one bracket main body, and two groups of second assembly seats are fixedly connected to the upper surface of the other bracket main body. Positioning columns are fixedly connected to the upper surfaces of the two groups of second assembly seats, and mounting holes are formed in the upper surfaces of the two first assembly seats.

[0024] As Figures 1 - 4As shown, a pressure-bearing column is slidably connected in the inner cavity of the mounting hole, and a plurality of pressure-bearing blocks are arranged in a ring shape on the outer edge of the upper surface of the pressure-bearing column. A through hole is opened at the center of the pressure-bearing column, and the bottom end of the pressure-bearing column is fixedly connected to a support rod, and the lower surface of the support rod is fixedly connected to the first inclined block. The inner side walls of the two first assembly seats are fixedly connected to a return spring, and the end of the return spring away from the first assembly seat is fixedly connected to the second inclined block, and the outer side of the second inclined block is fixedly connected to an extrusion plate, and the other side of the second inclined block is provided with an inclined surface. When installed on the bracket body 1, one end of the power battery is placed on the positioning column 16, and the other end of the power battery is placed on the surface of the pressure block 8. As the gravity of the power battery drives the support rod 10 downward through the pressure column 7, the support rod 10 applies a lateral force to the second inclined block 12 through the first inclined block 11. At this time, the second inclined block 12 drives the extrusion plate 13 to push outward and compress the reset spring 15 to fix the power battery with a mark, fill and fix the gap in the power battery, avoid shaking of the power battery, and improve the safety of the power battery.

[0025] Working principle: When in use, multiple groups of auxiliary support components are added between the bracket body 1 to enhance the bearing capacity of the bracket body 1, and high-strength bolts are used to ensure the stability and durability of the connection. By adjusting the height of the nut 21 in the prestressed bolt 20, the degree of compression of the damping block 22 on the reinforcement beam 17 is adjusted, thereby further improving the bearing capacity of the bracket body 1 while reducing the noise generated by vibration. When repairing the car, the battery needs to be disassembled, and the battery will be bound by the bracket body 1, resulting in shaking when the battery is installed and fixed after the car repair is completed, affecting the safety of the battery. By adding an adjustment component, the gap in the power battery can be filled and fixed to prevent the power battery from shaking. When the power battery is installed on the bracket body 1, one end of the power battery is placed on the positioning column 16, and the other end of the power battery is placed on the surface of the pressure block 8. As the gravity of the power battery drives the support rod 10 downward through the pressure column 7, the support rod 10 applies a lateral force to the second inclined block 12 through the first inclined block 11. At this time, the second inclined block 12 drives the extrusion plate 13 to push outward and compress the reset spring 15 to fix the power battery with a mark, avoid safety hazards caused by battery shaking, and improve the safety of the device.

[0026] The above are only the preferred embodiments of the present utility model, and do not limit the present utility model in other forms. Any person skilled in the relevant art may use the technical content disclosed above to make changes or modifications into equivalent embodiments with equivalent changes and apply them to other fields. However, as long as it does not depart from the technical solution content of the present utility model, any simple modification, equivalent change and modification made to the above embodiments based on the technical essence of the present utility model still fall within the protection scope of the technical solution of the present utility model.
