Description

Technical Field

[0001] The utility model relates to the technical field of PCU assembly brackets, in particular to a PCU assembly bracket with a shock absorbing function. Background Art

[0002] The PCU assembly is a power control unit, which is a combination component or module of a power controller that integrates regulation, monitoring and protection functions. The PCU assembly is usually used in electric vehicles or hybrid vehicles to manage and control the energy flow between the battery system and the electric drive system.

[0003] The PCU assembly is installed through a bracket, but the existing bracket can only fix the PCU assembly. When it is bumped, it has no effective shock-absorbing effect, resulting in serious wear of the PCU assembly and the bracket. The connection wires are not firm enough due to bumps during long-term use. Therefore, we propose a PCU assembly bracket with shock-absorbing function to solve the existing problem. Utility Model Content

[0004] The purpose of the utility model is to provide a PCU assembly bracket with a shock absorbing function in view of the problems existing in the background technology.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a PCU assembly bracket with shock absorption function, comprising a bracket assembly base, a top plate, a spring, a mounting bracket, a pressure plate and an oil cylinder, the outer walls on both sides of the bracket assembly base are provided with mounting brackets, the upper end of the mounting bracket is provided with equidistantly distributed springs, an oil cylinder is provided inside the spring, a sealing ring is embedded and installed inside the oil cylinder, a plug rod is slidably installed inside the sealing ring, a piston slidably installed inside the oil cylinder is provided on the upper end of the plug rod, support strip 1 and support strip 2 are respectively provided on the inner walls on both sides of the bracket assembly base, a top plate is provided on the upper end of the bracket assembly base, a pressure plate is provided below the top plate, rubber strips are provided at the lower end of the pressure plate, and compression springs are provided at the four corners of the upper end of the pressure plate.

[0006] Preferably, both ends of the piston are provided with relatively distributed one-way valves, and the one-way valves have opposite flow directions. When the piston squeezes the hydraulic oil on the inner wall of the oil cylinder, the hydraulic oil flows into the opposite spatial axis through the one-way valve. The two relatively distributed one-way valves ensure that the two-way squeezing force can ensure the passage of the hydraulic oil.

[0007] Preferably, the upper end of the oil cylinder is provided with a side plate connected to the outer wall of one side of the bracket assembly base, the upper end of the spring is connected to the side plate, and the lower end of the plug rod is connected to the lower end of the mounting bracket. The side plate supports the spring and the upper end of the oil cylinder, and the lower end of the guide rod is supported by the mounting bracket.

[0008] Preferably, a hinge is provided on one side of the upper end of the top plate, and one end of the hinge is connected to one side of the upper end of the first support bar. The top plate is rotatably supported at the upper end of the second support bar through the hinge.

[0009] Preferably, the support bar 2 and one side of the top plate are provided with mounting grooves. The mounting grooves are used for inserting bolts, and after the inserted bolts are fixed by nuts, one end of the bolts is fixed to the top plate located at the upper end of the support bar 1.

[0010] Preferably, the top plate and the pressure plate are provided with wiring holes distributed in a rectangular array, and the wiring holes ensure the passage of the PCU assembly connection wires.

[0011] Preferably, the upper end of the compression spring is connected to the top plate, and the four corners of the upper end of the top plate are provided with guide rods that are slidably plugged into the spring. The four corners of the upper end of the top plate are provided with through holes, and the guide rods are slidably plugged into the through holes. The installation line reserved during installation has a reserved movement stroke when pulling to avoid directly pulling the wiring and the power connection end of the PCU assembly. The rubber strip is in flexible contact with the upper end of the PCU assembly and flexibly presses the wiring. When the compression spring moves longitudinally, the upper end of the guide rod slides longitudinally inside the top plate to be guided by the guide rod.

[0012] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0013] 1. The mounting bracket of the utility model is elastically supported by multiple springs between the bracket assembly base to buffer the impact force, and a damping oil cylinder is arranged inside the spring to apply a damping force to the spring shaking force. When the PCU assembly inside the bracket assembly base is bumpy during use, the shock absorption protection is performed on the PCU assembly, which reduces the loss of the PCU assembly during use;

[0014] 2. At the same time, the upper end of the PCU assembly is elastically pressed by an elastically supported pressure plate to protect the upper end of the PCU assembly, and the wiring connected to the PCU assembly is pressed and held firmly. BRIEF DESCRIPTION OF THE DRAWINGS
