Description

Technical Field

[0001] The utility model relates to the technical field of charging modules, in particular to a charging module housing structure which is convenient for assembly and disassembly. Background Art

[0002] The charging module in the charging pile is the "heart" of the charging pile and an important part of DC fast charging. It is responsible for the AC-DC conversion between the equipment and the vehicle to achieve seamless charging. It mainly converts external power, such as mains electricity, into DC power that meets the charging requirements of electric vehicles, providing safe, efficient and stable charging services for electric vehicles. The charging module not only provides energy and electricity, but also controls and converts the circuit to ensure the stability of the power supply circuit. The performance of the module not only directly affects the overall performance of the charging pile, but also relates to charging safety issues. It is an important part of the charging pile that cannot be ignored.

[0003] For example, the Chinese authorized patent "A structure of a DC charging module for a DC charging pile" with announcement number CN211252246U includes a shell, a heat absorbing plate is fixedly connected to each fixing seat, a number of heat conducting mechanisms are fixedly connected to each heat absorbing plate, an air guide hood is fixedly connected to the shell, the heat conducting mechanism is located inside the air guide hood, the air guide hood is connected to a number of fans, air outlets are provided at both ends of the air guide hood, an upper frame is fixedly connected to the upper end of the shell, an upper cover is fixedly connected to the upper frame, a number of tips are fixedly connected to the upper end of the upper frame, a fixing frame is fixedly connected to the upper end of the upper frame, fixing mechanisms are connected to both sides of the fixing frame, and a protective cover is connected to the fixing mechanism. The heat is extracted through the heat conducting mechanism, and the fan blows out the heat, so dust will not be brought into the shell, and the charge is released in the form of tip discharge, so static electricity will not be generated.

[0004] Although the above-mentioned prior art can be assembled with a charging pile, the charging module itself is heavy and is in close contact with the installation compartment during disassembly, making it difficult to remove and time-consuming and labor-intensive. Therefore, it does not meet existing needs. In this regard, we propose a charging module shell structure that is easy to disassemble and assemble. Utility Model Content

[0005] The purpose of the utility model is to provide a charging module housing structure that is convenient for assembly and disassembly, so as to solve the problem of inconvenient assembly and disassembly between the charging module and the charging pile proposed in the above background technology.

[0006] To achieve the above object, the utility model provides the following technical solution: a charging module housing structure that is easy to disassemble and assemble, comprising a housing, a fixing plate is provided at the front end of the housing, and the fixing plate and the housing are fixed by screws; and further comprising:

[0007] A guide groove is arranged at the bottom of the housing, and the guide groove is an H-shaped structure. Sliding seats are installed on both sides of the guide groove, and the sliding seats and the guide groove are slidably limited. A connecting rod is arranged between the sliding seats, and the connecting rod is welded and fixed to the sliding seat;

[0008] The shock absorbing seat is arranged inside the sliding seat, and the shock absorbing seat and the sliding seat are slidably limited. A plurality of pulleys are installed at the bottom of the shock absorbing seat, and the pulleys are connected to the shock absorbing seat through a rotating shaft.

[0009] Preferably, a knob is rotatably mounted at the middle position of the front end of the fixed plate, and a driving bevel gear is fixedly mounted on the shaft located inside the shell, a driven bevel gear is mounted below the driving bevel gear, and the driven bevel gear is meshingly connected to the driving bevel gear, a screw is mounted on the shaft at the lower end of the driven bevel gear, and the screw is rotatably connected to the shell, a lifting block is fixedly mounted on the upper end of the sliding seat, and the lifting block is limited by sliding with the shell, the lower end of the screw extends to the interior of the lifting block, and the screw and the lifting block are matched through a thread.

[0010] Preferably, slide grooves are provided on both sides of the front end of the fixed plate, a plug plate is installed inside the slide groove, and the plug plate cooperates with the slot on the inner wall of the charging pile installation compartment, and a push rod is fixedly installed at the front end of the plug plate, and the push rod is located outside the slide groove.

[0011] Preferably, a shock absorbing cavity is provided on both sides between the sliding seat and the shock absorbing seat, extension blocks are fixedly provided on both sides of the shock absorbing seat, and the extension blocks are located inside the shock absorbing cavity, a damper is installed inside the shock absorbing cavity, and both ends of the damper are respectively fixed to the sliding seat and the extension block, and a shock absorbing spring is installed outside the damper.

[0012] Preferably, a handle is installed above the front end of the fixing plate, and the handle is fixed to the fixing plate by welding.

[0013] Preferably, the height of the plug board is smaller than the height of the slot on the inner wall of the charging pile installation compartment.

[0014] Preferably, the pulley is made of rubber.

[0015] Compared with the prior art, the beneficial effects of the utility model are:

[0016] 1. The utility model provides a pulley at the bottom of the shell. When the shell body of the charging module is installed, the sliding seat used to connect the pulley is located at the uppermost end of the guide groove. Therefore, the height of the shell is less than the height of the installation bin. Therefore, the shell can be placed inside the installation bin without fine alignment, so that the bottom pulley contacts the installation bin, and then the handle is pushed to cooperate with the pulley to make the shell easily enter the installation bin and reach the specified position. Then, the knob is turned to drive the active bevel gear to rotate, and the screw is driven to rotate under the meshing with the driven bevel gear. The screw and the inner screw hole of the lifting block are rubbed, and the lifting block drives the sliding seat to descend under the guiding effect of the shell on the lifting block. The reaction force orders the height of the shell to be raised until the upper end surface contacts the installation bin, ensuring the stability of the shell inside the installation bin. Similarly, when taking out the charging module, it is only necessary to flip the knob to make the sliding seat shrink toward the inside of the guide groove, thereby reducing the height of the shell. At this time, the staff can easily pull out the charging module, thereby providing convenience for daily maintenance work. The disassembly and assembly structure is convenient and easy to operate, and can improve the installation stability of the charging module.

[0017] 2. The utility model provides a shock-absorbing cavity on both sides between the sliding seat and the shock-absorbing seat. The damper inside the shock-absorbing cavity is used to connect the sliding seat and the shock-absorbing seat. When the charging pile vibrates due to the external environment, the damper will shrink and the shock-absorbing spring will be compressed. The vibration force is converted under elastic deformation, thereby reducing the impact on the charging module and avoiding the problem of reduced service life of the charging module due to vibration.

[0018] 3. The utility model provides push rods on both sides of the front end of the fixing plate. When the shell reaches the specified position in the installation bin, the staff holds the push rod and pushes it toward the outside of the fixing plate, so that the plug plate inside the slide groove extends outward until it enters the slot on the inner wall of the installation bin, forming a limit for the shell at this position, further improving the installation stability.

[0035] Working principle: When the charging module housing is installed, the sliding seat 5 for connecting the pulley 7 is located at the uppermost end of the guide groove 4, so the height of the housing 1 is less than the height of the installation bin, so the housing 1 can be placed inside the installation bin without precise alignment, so that the bottom pulley 7 contacts the installation bin, and then the handle 3 is pushed, and the pulley 7 is cooperated to make the housing 1 easily enter the installation bin and reach the specified position, and then the knob 9 is turned to drive the active bevel gear 12 to rotate, and the screw 13 is driven to rotate under the meshing with the driven bevel gear 14, and the screw 13 rubs against the inner screw hole of the lifting block 15, and the lifting block 15 is pressed by the housing 1. The guiding action causes the lifting block 15 to drive the sliding seat 5 to descend, and the reaction force causes the height of the shell 1 to rise until the upper end surface contacts the installation bin, thereby ensuring the stability of the shell 1 inside the installation bin. By holding the push rod 10 and pushing toward the outside of the fixed plate 2, the plug plate 16 inside the slide groove 11 extends outward until it enters the slot on the inner wall of the installation bin, thereby forming a limit for the shell 1 at this position. Similarly, when taking out the charging module, it is only necessary to reverse the knob 9 to allow the sliding seat 5 to shrink toward the inside of the guide groove 4, thereby lowering the height of the shell. At this time, the staff can easily pull out the charging module, thereby providing convenience for daily maintenance work.
