Background
With the development of vehicle-mounted electronics and the increasing degree of vehicle electronics, especially the increase of functions such as automatic driving and active safety, particularly the use of high-performance processors in vehicle-mounted electronics, the on-board domain controllers are rapidly increasing.
The domain controller is used as an important part of the vehicle-mounted electronic components, the quality of the product determines the stability and performance requirements of the whole vehicle-mounted control system, the working environment of the domain controller needs to work in a high-temperature and high-humidity environment, and the air tightness requirement on the product is very high. In the development and production process, the domain controller needs to be analyzed and repaired, and the shell of the product is very difficult to detach due to the existence of the sealant, so that the shell is very difficult to detach for some controllers with water-cooling original elements.
At present, most of sealing products are disassembled by destructive testing, so that analysis and maintenance of the disassembled products are very difficult, and some products cannot be analyzed and used after being disassembled, so that the quality of repairing parts is difficult to guarantee, and meanwhile, the repairing work efficiency and the actual production are influenced.

Detailed Description
The present utility model will be described in further detail with reference to the drawings and examples, in order to make the objects, technical solutions and advantages of the present utility model more apparent. It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the scope of the utility model.
The utility model provides a shell removing device of a domain controller, which comprises a supporting body 1, a workbench 2 fixedly arranged on the supporting body 1, a positioning structure 3 arranged on the workbench and used for fixing the domain controller on the workbench 2, a cover removing mechanism 4 arranged on the workbench 2 and a shell removing mechanism 5 arranged on the supporting body 1, as shown in figure 1.
As shown in fig. 1, the positioning structure 3 includes a support column 31 fixed to the table 2 and a bolt 32 fixing the domain controller to the support column 31. When the shell removing work is performed, the mounting position of the domain controller to be shell removed is placed on the support column 31, and the mounting position is fixed on the support column 31 through the bolt 32, so that the domain controller is fixed on the workbench 2.
It should be noted that, the four support columns 31 are disposed in total, the four support columns 31 are distributed on the workbench 2 in a rectangular array, the support columns 31 are fixed on the mounting positions of the domain controller, and the bolts 32 penetrate through the mounting holes of the mounting positions and are in threaded connection with the support columns 31, so that the domain controller is fixed on the workbench 2.
Further, for convenience of operation, the workbench 2 is provided with a placement groove 21 for placing the bolt 32; when the domain controller is positioned, firstly, the bolts 32 on the support columns 31 are detached and placed in the placing grooves 21, and after the installation positions on the domain controller are aligned with the support columns, the bolts 32 are taken to fix the installation positions of the domain controller on the support columns 31; by arranging the placement groove 21, the bolts 32 are stored when the domain controller is positioned, so that the risk of losing the bolts 32 can be effectively reduced while the bolts 32 are conveniently taken.
As shown in fig. 1, the cover removing mechanism 4 includes a cross frame 41 fixedly disposed at a position above the table 2 corresponding to the positioning structure 3, a clamp 42 longitudinally moving below the cross frame 41, and a first screw 43 disposed on the cross frame 41 for driving the clamp 42 to longitudinally move. Wherein, in order to ensure the stability of the movement of the clamp 42, the clamp 42 is prevented from interfering the rotation of the first screw 43 after being clamped on the upper cover of the domain controller; the first screw 43 is connected with the clamp 42 through a bearing 431. When the cover is detached, the first lead screw 43 is rotated, so that the first lead screw 43 moves downwards on the transverse frame 41, the clamp 42 is driven to approach the domain controller to be detached, after the clamp 42 moves to the working position, the clamp 42 is clamped on the upper cover of the domain controller, and then the first lead screw 43 is reversely rotated, so that the first lead screw 43 moves upwards on the transverse frame 41, so that the clamp 42 pulls the upper cover upwards, and the upper cover is separated from the shell.
Before the cover is removed, an external tool is required to remove the screw between the housing and the upper cover of the lock domain controller, and then the upper cover is separated from the housing by using the cover removing mechanism 4.
As shown in fig. 1 and 3, the fixture 42 includes a fixed end 421 disposed on the first screw 43, a movable end 422 inserted into one end of the fixed end 421, and a fastener 423 disposed on the fixed end 421 for locking the movable end 422 to the fixed end 421. When the cover is detached, the fastener 423 is firstly loosened, the movable end 422 of the clamp 42 is pulled out of the fixed end 421, so that the clamp 42 is in a state of maximum length, and when the clamp 42 moves to the upper cover position of the domain controller, the movable end 422 is pushed, so that the movable end 422 is contracted into the inside of the fixed end 421, and the movable end 422 and the fixed end 421 are clamped on the upper cover of the domain controller in a matched manner.
It should be noted that, when the clamp 42 moves to the upper cover position, the clamping edge of the fixed end 421 contacts with the edge of the upper cover, so as to be clamped on the upper cover in cooperation with the movable end 422.
As shown in fig. 1, the shell removing mechanism 5 includes a push rod 51 longitudinally penetrating through the workbench 2 and used for contacting with the water inlet pipe and the water outlet pipe of the domain controller, and a driving mechanism 52 for driving the push rod 51 to move longitudinally. When the shell is removed, the ejector rods 51 are driven to move upwards through the driving mechanism 52, and after the two ejector rods 51 are respectively contacted with the end parts of the water inlet pipe and the water outlet pipe of the water cooling element, the ejector rods 51 are continuously driven to move upwards, so that the ejector rods 51 are pushed upwards, the water inlet pipe and the water outlet pipe of the water cooling element are separated from the shell of the domain controller, and the shell removing work is completed.
It should be noted that, for the domain controller without the water cooling element, the control main board is generally pressed inside the shell through the upper cover, and the control main board can be directly taken out after the cover is removed.
As shown in fig. 1 and 2, the driving mechanism 52 includes a lifting plate 521 longitudinally moving inside the supporting body 1, a second screw 522 longitudinally penetrating the lifting plate 521 and rotatably connected to the supporting body 1, and a driving shaft 523 rotatably mounted on the supporting body 1 for driving the second screw 522 to rotate, and the ejector rod 51 is fixed on the lifting plate 521; wherein the drive shaft 523 is geared with the second lead screw 522. When the shell is removed, the driving shaft 523 is rotated, so that the driving shaft 523 drives the second screw 522 to rotate, the lifting plate 521 moves upwards, the ejector rod 51 is driven to move upwards to push the water-cooled element, the water-cooled element is separated from the shell, and the shell removing work is completed.
Further, in order to ensure the stability of the operation of the lifting plate 521, the driving mechanism 52 further includes a guiding column 524 fixedly disposed on the supporting body 1 and longitudinally penetrating through the lifting plate 521. The lifting plate 521 is guided by the guide post 524, so that the lifting plate 521 is prevented from being driven to rotate when the second screw 522 rotates, and stable longitudinal movement of the lifting plate 521 is ensured.
The foregoing description of the preferred embodiments of the utility model is not intended to be limiting, but rather is intended to cover all modifications, equivalents, and alternatives falling within the spirit and principles of the utility model.
