[0038] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0039] See also Figure 1 to Figure 2 As shown;

[0040] A DPU lifting device of this embodiment, the device 10 comprises:

[0041] A fixing frame 1; and

[0042] A movable frame 2 movably connected to one end of the fixed frame 1;

[0043] A fixed frame support rod 102 is extended in the vertical direction from one end of the fixed frame 1 away from the movable frame 2, and both the fixed frame support rod 102 and the movable frame 2 have a convex portion extending toward the DPU 20 hoisting position;

[0044] The convex part is provided with a locking pin 3 which can be inserted into the hole of the hanging part of the DPU 20;

[0045] A plurality of lifting rings 4 are provided on the fixing frame 1 .

[0046] Specifically, this embodiment discloses a device 10 suitable for lifting and transporting a DPU controller, which includes a fixed frame 1 and a movable frame 2, wherein the fixed frame 1 and the movable frame 2 are placed on the upper end of the DPU controller, and are connected to the corresponding holes of the DPU 20 through four locking pins 3 of the convex portion to achieve the function of lifting the DPU 20. At the same time, the device as a whole is lifted up with the aid of external lifting equipment through multiple lifting rings 4 to lift the device and the DPU 20 as a whole.

[0047] Preferably, the fixing frame 1 of this embodiment includes:

[0048] horizontal frame 101; and

[0049] A fixed frame support rod 102 connected to the end of the horizontal frame 101;

[0050] The fixing frame 1 is an aluminum alloy frame structure;

[0051] The horizontal frame 101 is evenly distributed with four lifting rings 4 .

[0052] In this embodiment, a screw rod is disposed at the lower part of the lifting ring 4 , and the lifting ring 4 is threadedly connected to the horizontal frame 101 via the screw rod.

[0053] This embodiment further defines the structure of the fixed frame 1, which includes a horizontal frame 101 and a fixed frame support rod 102. There are two fixed frame support rods 102, which are fixed at one end of the horizontal frame 101, and four lifting rings 4 are evenly distributed on the upper part of the horizontal frame 101. This embodiment uses four lifting rings 4 threadedly connected to the horizontal frame 101 to ensure the balance of the suspended DPU 20.

[0054] In order to reduce the overall weight, the fixing frame 1 of the present embodiment is made of aluminum alloy as a whole, which is light in weight and high in strength.

[0055] Preferably, the movable frame 2 of this embodiment includes:

[0056] Two movable frame support rods 201 hinged to the horizontal frame 101 via a rotating shaft; and

[0057] A movable frame horizontal rod 202 is connected to the lower ends of the two movable frame support rods 201 , and a handle 5 is threadedly connected to the outer side of the movable frame horizontal rod 202 .

[0058] The movable frame 2 of this embodiment is an aluminum alloy frame.

[0059] This embodiment further defines the structure of the movable frame 2, which is provided with two movable frame support rods 201 and a movable frame horizontal rod 202. The movable frame support rod 201 is hinged at the end of the horizontal frame 1 through a rotating shaft, and the movable frame horizontal rod 202 is connected to the lower end of the movable frame support rod 201, and a handle 5 is installed on the outer side of the movable frame horizontal rod 202 by bolts.

[0060] Preferably, the material of the lock pin 3 of this embodiment is iron material; the top of the lock pin 3 is chamfered. The lock pin 3 is heat treated on the outside to make the lock pin 3 more wear-resistant and increase the service life, and the top of the lock pin 3 is chamfered to facilitate the lock pin 3 to enter the DPU hole more easily, and the bottom is threaded and can be threadedly connected to the frame.

[0061] In addition, the handle 5 of this embodiment is made of plastic, has a smooth feel and is light in weight.

[0062] The locking pin 3 of this embodiment is arranged along the Z direction to facilitate cooperation with the DPU hole. The surface where the locking pin 3 is located is the XY surface, which is used to support the weight of DPU20. This embodiment adopts the cooperation of the fixed frame 1 and the movable frame 2. During the grasping process, the movable frame 2 is opened so that the distance of the locking pin 3 is greater than the wide side of the DPU20, which is convenient for the tooling to fall, thereby facilitating the smooth grasping action of the DPU20. The overall aluminum alloy material reduces its own weight, ensures the overall structural strength, and will not bend or deform during use. After the workpiece is placed in place, the tooling is lowered. At this time, one side of the movable frame 2 can be opened. After opening, the distance between the locking pins 3 on both sides is greater than the wide side of the DPU20, so that the tooling is easy to detach.

[0063] This embodiment uses four locking pins to facilitate fixing the DPU 20 to the tooling, and the problem of falling off will not occur during the transfer process.

[0064] In the above technical solution, the utility model provides a DPU lifting device having the following

[0065] Beneficial effects:

[0066] The DPU lifting device 10 of the utility model solves the problem that when the rear suspension assembly of a new energy passenger car is assembled, the DPU 20 has a large size and a heavy weight, and it is difficult for the operator to manually lift it onto the assembly pallet, which also poses a safety hazard.

[0067] The DPU lifting device of the utility model effectively reduces the difficulty of assembling the DPU controller and can avoid potential safety hazards during the assembly process.

[0068] The above only describes some exemplary embodiments of the present invention by way of illustration. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
