[0022] A typical embodiment of this utility model is as follows: Figure 1As shown, a battery high-voltage box mounting frame assembly includes a frame body 1 and a sealing plate 2. The sealing plate 2 covers the outside of the frame body 1, and the battery high-voltage box is placed inside the frame body 1, thereby protecting the battery high-voltage box by means of the frame body 1 and the sealing plate 2.

[0023] like Figure 2 As shown, the frame body 1 includes uprights 101 and connecting rods 102. Both uprights 101 and connecting rods 102 are rectangular tubes. There are four uprights 101, which are connected to each other by connecting rods 102. Specifically, the top and middle of two adjacent uprights 101 are connected by connecting rods 102. There are eight connecting rods 102. The four uprights 101 and the eight connecting rods 102 form a rectangular frame structure. Multiple first support rods 103 are arranged between two parallel connecting rods 102 at the top. The multiple first support rods 103 are arranged side by side. Multiple second support rods 104 are arranged between two parallel connecting rods 102 in the middle. The multiple first support rods 103 and the multiple second support rods 104 are arranged vertically. The high-voltage battery box is placed between the first support rods 103 and the second support rods 104. The first support rods 103 support the top sealing plate 2 to prevent personnel from stepping on the top of the frame and bending the sealing plate 2 during maintenance.

[0024] The upright 101 has multiple first through holes 105 arranged side by side along the length of the upright 101. The connecting rod 102 has multiple second through holes 106 arranged side by side along the length of the connecting rod 102. Nuts 107 are provided on the side of the first through holes 105 and the second through holes 106 away from the sealing plate 2. Bolt holes are provided on the outer surface of the sealing plate 2 at positions corresponding to the first through holes 105 and the second through holes 106. The sealing plate 2 can be fixed to the frame body 1 by bolts.

[0025] A bending plate 3 is provided at the bottom of the upright 101. The bending plate 3 is L-shaped and includes a horizontal plate and a side plate. The horizontal plate is fixedly connected to the bottom end face of the upright 101, and the vertical plate is fixedly connected to the bottom side wall of the upright 101, thereby increasing the contact area between the bending plate 3 and the upright 101 and ensuring the stability of the connection between the bending plate 3 and the upright 101. A reinforcing plate 4 is also connected between the horizontal plate and the upright 101, thereby improving the structural strength between the bending plate 3 and the upright 101.

[0026] A frame fixing seat 5 is provided below the bending plate 3. The frame fixing seat 5 is fixed on the frame of the engineering machinery. The frame fixing seat 5 and the bending plate 3 are connected by a shock absorber 6. The shock absorber 6 can reduce the vibration of the battery high voltage box.

[0027] It should be noted that shock absorber 6 is a common shock absorber on the market; any shock absorber that can achieve vertical shock absorption is acceptable.

[0028] Specifically, the frame fixing seat 5 includes a fixing plate and a support plate. The fixing plate is C-shaped and made of bent steel plate. It includes a top plate, a bottom plate and a side plate. There are two support plates, which are symmetrically arranged between the top plate and the bottom plate. The top surface of the support plate is connected to the top plate, the bottom surface is connected to the bottom plate and the side surface is connected to the side plate. The support plate improves the support strength of the frame fixing seat 5.

[0029] The top of the shock absorber 6 is fixedly connected to the horizontal plate of the bending plate 3, and the bottom of the shock absorber 6 is fixedly connected to the top plate of the frame fixing seat 5. The horizontal plate and the top plate increase the force-bearing area of ​​the shock absorber 6 and improve the shock absorption effect of the shock absorber 6.

[0030] A manual maintenance switch (MSD) is located on one side of the battery high-voltage box. This switch can be used to cut off the high-voltage power output from the battery, allowing for power disconnection during battery maintenance or in emergencies. A maintenance window 7 is provided on the cover plate 2 opposite the manual maintenance switch for easy operation.

[0031] In other embodiments, the cover plate 2 opposite to the manual maintenance switch can be replaced with a box door. The box door and the cover plate 2 are connected by a pivot. When the manual maintenance switch needs to be operated, the box door can be opened. The box door is equipped with a lock body, which can be used to close the box door, thereby achieving all-round protection for the battery box.

[0032] This utility model sets up a frame body and places the high-voltage battery box inside the frame body. At the same time, a sealing plate is set on the outside of the frame body. When the high-voltage battery box is placed outside the battery compartment, it can be effectively protected. By setting a shock absorber at the bottom of the frame body and connecting the shock absorber to the frame fixing seat, the frame fixing seat is fixed on the frame of the construction machinery. This can reduce the vibration of the high-voltage battery box during the operation of the construction machinery and prevent damage to the high-voltage battery box.
