Technical Field

[0001] This utility model relates to the field of charging pile technology, specifically to a fan screw and nut fixing fixture applied to the power module of a charging pile. Background Technology

[0002] Charging piles, also known as electric vehicle charging stations or electric vehicle power supply equipment, are devices that provide electrical energy to electric vehicles, enabling them to store enough electricity to support their operation. The charging pile power module, as the core of the charging pile, is also developing towards higher power and standardized modularity. To meet the growing market demand for fast charging, the power of charging modules is constantly increasing, with a trend towards higher module power density.

[0003] The fan of the charging pile power module serves as its main heat dissipation component, ensuring that the charging pile power module operates stably within the rated temperature range and extending its lifespan.

[0004] To quickly assemble multiple fans into the power module of a charging pile, special tooling is required to meet the requirements. Therefore, there is an urgent need for a fan screw and nut fixing tooling for the power module of a charging pile to solve the technical defects mentioned above. Utility Model Content

[0011] As a further technical solution of this utility model, a limiting nut is provided on the cooling fan, and the limiting nut is connected to the mounting hole of the cooling fan.

[0012] Compared with the prior art, the beneficial effects of this utility model are: the fixing tool for fan screws and nuts of charging pile power modules not only realizes the function of enhancing installation efficiency and facilitating positioning, but also realizes the function of stable installation;

[0013] (1) By setting up a quick clamp, connecting rod, limit sleeve, support column, nylon isolation column positioning pin plate, fan limit plate and limit screw, when installing the cooling fan, the tooling base needs to be placed in the power module area of ​​the charging pile first, and then the cooling fan to be installed and the limit nut for installation are placed on the fan limit plate. Then the worker pulls the quick clamp upward, and the connecting rod on the quick clamp can push the support column to move upward. The support column drives the nylon isolation column positioning pin plate to move upward, which can push the cooling fan and the limit nut for installation to be quickly installed in the inner shell of the charging pile. Then the limit nut is fixed on the shell. This structure realizes the quick installation of multiple cooling fans and enhances the efficiency of auxiliary installation.

[0014] (2) By setting up a positioning pin plate slide rod, a nylon isolation column positioning pin plate, and a limiting slide sleeve, when the tooling is used to assist in the installation of the cooling fan, the quick clamp can push the nylon isolation column positioning pin plate to move upward, and the limiting slide sleeve on the nylon isolation column positioning pin plate can slide outside the positioning pin plate slide rod to achieve the stability of movement, thereby enhancing the positioning effect of the installation.

[0015] (3) By setting up a cooling fan, a limiting screw, a heat dissipation hole and a limiting nut, when installing the cooling fan, it is necessary to first place it on the fan limiting plate. The limiting screw on the fan limiting plate can limit the installation position of the cooling fan.

Limiting sleeves 12 are fixedly connected to both sides of the bottom end of the nylon isolation column positioning pin plate 7. A limiting screw 10 is fixedly connected to the top of the nylon isolation column positioning pin plate 7. A cooling fan 9 is placed above the fan limiting plate 8. An installation seat 11 is installed inside the fixture base 1. A quick clamp 3 is movably hinged to the bottom of the front end of the installation seat 11. A limiting sleeve 5 is fixedly connected to the front end of the installation seat 11. A support column 6 is provided inside the limiting sleeve 5. A connecting rod 4 is installed between the support column 6 and the quick clamp 3.

[0024] Specifically, such as Figure 1 and Figure 4As shown, the cooling fan 9 to be installed and the limiting nut 14 for installation are placed on the fan limiting plate 8. Then, the worker pulls the quick clamp 3 upward. The connecting rod 4 on the quick clamp 3 can push the support column 6 upward. The support column 6 drives the nylon isolation column positioning pin plate 7 to move upward, which can push the cooling fan 9 and the limiting nut 14 for installation to be quickly installed with the charging pile shell. Then the limiting nut 14 is fixed on the shell. This structure realizes the quick installation of multiple cooling fans 9.

[0025] The top of the nylon isolation column positioning pin plate 7 is fixedly connected to the limiting screw 10, and the limiting sleeve 12 is slidably connected to the outside of the positioning pin plate slide rod 2.

[0026] Specifically, such as Figure 1 and Figure 2 As shown, when the tooling auxiliary cooling fan 9 is installed, the quick clamp 3 can push the nylon isolation column positioning pin plate 7 to move upward. The limiting sleeve 12 on the nylon isolation column positioning pin plate 7 slides outside the positioning pin plate slide rod 2 to achieve stability of movement.

[0027] A charging pile housing is provided on the top of the tooling base 1, and a heat dissipation hole is provided on the top of the charging pile housing. A limit nut 14 is provided on the cooling fan 9, and the limit nut 14 is connected to the mounting hole of the cooling fan 9.

[0028] Specifically, such as Figure 1 and Figure 3 As shown, when installing the cooling fan 9, it needs to be placed on the fan limiting plate 8 first. The limiting screw 10 on the fan limiting plate 8 can limit the installation position of the cooling fan 9. The fan limiting plate 8 pushes the cooling fan 9 to the designated area and installs it through the limiting nut 14.

[0029] Working principle: First, place the fixture base 1 in the power module area of ​​the charging pile. Then, place the cooling fan 9 and the installation limit nut 14 on the fan limit plate 8. Next, the operator pulls the quick clamp 3 upward. The connecting rod 4 on the quick clamp 3 can push the support column 6 upward. The support column 6 drives the nylon isolation column positioning pin plate 7 upward, which can push the cooling fan 9 and the installation limit nut 14 to be quickly installed with the charging pile shell. Then, the limit nut 14 is fixed on the shell. This structure realizes the quick installation of multiple cooling fans 9. The limit screw 10 on the fan limit plate 8 can limit the installation position of the cooling fan 9. The fan limit plate 8 pushes the cooling fan 9 to the designated area and installs it through the limit nut 14. When the fixture assists in the installation of the cooling fan 9, the quick clamp 3 can push the nylon isolation column positioning pin plate 7 upward. The limit sliding sleeve 12 on the nylon isolation column positioning pin plate 7 slides outside the positioning pin plate slide rod 2 to achieve the stability of movement, thereby enhancing the positioning effect of the installation.
