Description

Technical Field

[0001] This utility model belongs to the field of charger maintenance technology, and specifically relates to an auxiliary device for disassembling and assembling a vehicle charger. Background Technology

[0002] With the development of new energy vehicles, the number of new energy vehicles on the road is increasing, which also increases the workload of inspection and maintenance. Therefore, higher requirements are placed on the speed of inspection and maintenance of new energy vehicles.

[0003] Chargers for new energy vehicles mainly include electric vehicle chargers and on-board chargers. An electric vehicle charger is a device specifically designed for charging the battery of an electric vehicle, possessing specific power conversion functions. It can be divided into DC chargers and AC chargers. An on-board charger is a charger fixedly installed on an electric vehicle, capable of safely and automatically fully charging the electric vehicle's power battery. An on-board charger mainly consists of the following parts: an input interface, a control unit, a power unit, a low-voltage auxiliary unit, and an output port. These parts are soldered onto an integrated circuit board, which is then installed inside a protective housing to ensure stable operation. To maintain relative stability between the integrated circuit board and the protective housing during vehicle vibrations, in addition to bolts, several bosses are typically installed inside the housing. The integrated circuit board is then fixed to these bosses with adhesive to increase its stability within the housing. However, this approach has a problem: when repairing the on-board charger, after removing the fixing bolts of the protective cover and the integrated circuit board, the integrated circuit board is still partially bonded to the protective cover. It is necessary to pry the edge of the integrated circuit board with your hands or tools to separate the integrated circuit board from the protective cover. This can easily damage the edge of the circuit board due to uneven force, and the disassembly efficiency is slow and cannot keep up with the speed requirements. Utility Model Content

[0033] Example 1

[0034] like Figure 1 The diagram shows a structural schematic of an auxiliary device for disassembling and assembling a vehicle charger, comprising:

[0035] Platform 1 is used to place the charger 4 to be repaired; the platform 1 can be made of aluminum plate, which can not only ensure strength and hardness, but also reduce the overall weight.

[0036] Fixing part 2; The fixing part 2 is used to fix the charger housing 41 on the platform 1; so that the charger 4 will not move when it is disassembled, which facilitates disassembly;

[0037] Lifting section 3; the lifting section 3 is mounted on the platform 1; the lifting section 3 is provided with a lifting mechanism 32 that can move up and down relative to the platform 1; the bottom of the lifting mechanism 32 is provided with several welding parts 327 for welding to the solder feet on the circuit board 42 inside the charger 4; after the welding parts 327 are welded to the solder feet, the lifting mechanism 32 is activated to lift the circuit board 42, so that the circuit board 42 can be separated from the charger housing 41; the welding parts 327 can move relative to the plane of the circuit board 42, so that the disassembly personnel can adjust the position of the welding parts 327, so that the circuit board 42 can be subjected to uniform force when pulling the circuit board 42.

[0038] By setting several welding parts 327 on the lifting mechanism 32 and welding them to the solder feet on the circuit board 42, when the lifting mechanism 32 is activated to raise the circuit board 42, the force on the force-bearing parts of the circuit board 42 is uniform and stable. This can overcome the problem that the edge parts of the circuit board 42 are easily damaged due to uneven force, and also improve the disassembly efficiency of the charger 4.

[0039] In a specific implementation, the lifting part 3 includes: a support frame 31; both sides of the support frame 31 are respectively installed on the platform 1; and the lifting mechanism 32 is movably installed on the support frame 31.

[0040] In specific implementation, the lifting mechanism 32 includes:

[0041] A screw 322 is provided; a rotating handle 321 is provided at the top of the screw 322; the screw 322 is connected to the support frame 31 by a thread; rotating the handle 321 causes the screw 322 to rotate relative to the support frame 31, thereby allowing the screw 322 to move up and down on the support frame 31; furthermore, in this embodiment, the rotating handle 321 is a rod horizontally welded to the top of the screw 322; of course, other structures can also be used, such as a rotary handle 321;

[0042] Hanging plate 325; the hanging plate 325 is rotatably connected to the bottom of the screw 322, so that the hanging plate 325 can remain stationary during the rotation of the screw 322, and at the same time, the screw 322 can also drive the hanging plate 325 to rise or move relative to the platform 1 during the upward process; the bottom of the hanging plate 325 is provided with several hanging rods 326 that can move left and right and up and down relative to the plane of the hanging plate 325, so that the hanging rods 326 can move their positions relative to the plane of the circuit board 42 to adjust the force position of the circuit board 42 when pulling the circuit board 42; the welded part 327 Installed at the bottom end of the lifting rods 326, each lifting rod 326 has a welding component 327 at its bottom end. After adjusting the left-right and up-down distances of the lifting rods 326, the welding component 327 contacts the solder feet 43 on the circuit board 42, and each welding component 327 is soldered to the solder feet 43. Then, rotating the handle 321 causes the screw 322 to lift the lifting plate 325, lifting rods 326, welding components 327, and circuit board 42 relative to the platform 1, while the charger housing 41 is fixed on the platform 1, allowing the circuit board 42 to be separated from the charger housing 41. Furthermore, the number of lifting rods 326 can be increased or decreased according to the required pulling force.

[0043] In specific implementation, the lifting rod 326 is threaded; the upper part of the welded component 327 is provided with a threaded hole that is threadedly connected to the lifting rod 326. Because the welded component 327 will wear out with increased use, it is designed as a detachable structure, allowing for individual replacement of the welded component 327 when wear occurs, thus reducing the maintenance cost of the device. The threaded connection method is simple in structure and convenient for replacement.

[0044] In specific implementation, the hanging plate 325 is provided with several through holes 324; the upper end of the hanging rod 326 passes through the through holes 324 and is fixed to the hanging plate 325 by nuts. Furthermore, nuts are installed on the hanging rod 326 above the hanging plate 325 to form a limiting block, preventing the hanging rod 326 from falling out of the through holes 324; the vertical distance of the hanging rod 326 on the hanging plate 325 can be adjusted simply by loosening or tightening the nuts, and the horizontal distance of the hanging rod 326 on the hanging plate 325 can be adjusted simply by installing the hanging rod 326 in different through holes 324. The structure is simple and easy to use.

[0045] In specific implementation, the hanging plate 325 is provided with a connecting block 323; the connecting block 323 is provided with a through-hole; the bottom of the through-hole (the part near the hanging plate 325) is provided with an annular groove (not shown in the figure); the bottom of the screw 322 is provided with an annular boss (not shown in the figure); the bottom of the screw 322 passes through the through-hole; the boss is paired with the groove for installation. Furthermore, the boss can be designed to be separate from the bottom of the screw 322. After the bottom of the screw 322 passes through the through-hole, the boss is installed and then welded or otherwise fixed to the bottom of the screw 322. This allows the boss to act as an upper and lower limit when rotating in the groove, preventing the screw 322 from coming off the connecting block 323. Furthermore, the connecting block 323 is installed on the hanging plate 325 by bolts.

[0046] In specific implementation, the support frame 31 is provided with a lifting hole; the lifting hole has a thread that matches and is installed with the screw 322, so that when the screw 322 rotates, it can move up and down relative to the support frame 31 through the engagement of the thread. Furthermore, the upper part of the support frame 31 is provided with a through hole 324, and the bottom is provided with a separable threaded hole, so that when the threaded hole is worn, it can be replaced separately, reducing manufacturing costs and subsequent maintenance costs.

[0047] Furthermore, the support frame 31 adopts a portal frame structure; vertical moving slots are provided on the two side columns of the support frame 31. Furthermore, the left and right columns and the upper crossbeam of the support frame 31 are all made of the same type of aluminum profile, and the four sides of the aluminum profile are provided with moving slots, realizing the use of local materials and reducing manufacturing costs.

[0048] Furthermore, the fixing part 2 is movably mounted on the moving slot, so that the fixing part 2 can move up and down to adapt to different models of charger housing 41.

[0049] Furthermore, the fixing part 2 includes:

[0050] Fastener 22; the fastener 22 adopts a direct plate structure; further, the fastener 22 may adopt an angle aluminum structure;

[0051] Pressing component 21; the pressing component 21 is provided with an adjustment groove 23; furthermore, the pressing component 21 can also adopt an angle aluminum structure; the left part of the pressing component 21 is fixed to the fixing component 22, and the free end is pressed on the charger housing 41, so that the housing of the charger 4 is fixed on the platform 1.

[0052] A fixing bolt assembly 24; the fixing bolt assembly 24 passes through the adjustment groove 23 and the fixing member 22, and is used to install the fixing member 22 and the pressing member 21 on the moving groove.

[0053] Next, the working principle of this embodiment will be described in detail so that those skilled in the art can better understand this utility model:

[0054] First, place the charger 4 on the platform 1. Turn the handle 321 to lower the lifting rod 326 and the soldering part 327 onto the plane of the circuit board 42. Adjust the relative position of the charger 4 and the lifting rod 326 to find the correct soldering connection point. Then, adjust the height of the fixing part 22 so that the free end of the pressing part 21 can press against the charger housing 41. Tighten the fixing bolt group 24 to fix the fixing part 2 in place on the platform 1. Solder the soldering part 327 to the solder feet 43 on the circuit board 42. After the connection is secure, turn the handle 321 to raise the lifting plate 325, the lifting rod 326, and the soldering part 327, causing the circuit board 42 to rise and separate from the charger housing 41. Finally, use the high temperature of the soldering pen to separate the soldering part 327 from the solder feet 43 on the circuit board, completing the disassembly.

[0055] In summary, this application provides a structural schematic diagram of an auxiliary device for disassembling and assembling a vehicle charger, comprising: a platform for placing the charger to be repaired; a fixing part for fixing the charger housing to the platform; a lifting part mounted on the platform; a lifting mechanism that can move up and down on the lifting part; and several welding parts at the bottom of the lifting mechanism for soldering connections to solder joints on the circuit board inside the charger. After the welding parts are soldered to the solder joints, the lifting mechanism is activated to lift the circuit board, thus separating the circuit board from the charger housing. By setting several lifting rods on the lifting mechanism and evenly distributing them above the circuit board, and then soldering the welding parts at the bottom of the lifting rods to the solder joints on the circuit board before activating the lifting mechanism to lift the rods, the problem of uneven stress on the circuit board causing damage to the edges can be overcome, while also improving the disassembly efficiency of the charger.
