Technical Field

[0001] This utility model relates to the field of charging pile technology, specifically to a charging pile fixing base. 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. Charging piles are divided into public and private charging piles, and in terms of charging methods, they are divided into AC charging piles and DC charging piles. With the popularization of new energy vehicles, the demand for charging piles is increasing daily.

[0003] Currently, most existing charging piles are installed on the ground or walls. For ground-mounted vertical charging piles, in order to facilitate wiring at the bottom and reduce the impact of moisture, a fixed base is usually required. The fixed base can be pre-embedded in the foundation, and then the charging pile body is installed on the base. However, since the bottom of the pile body is often fixed to the base with expansion bolts, it is very difficult and inconvenient to unscrew and remove it when disassembly and maintenance are required. Moreover, reinstallation will also be affected, which greatly affects the actual application effect of the fixed base. Utility Model Content

[0004] The purpose of this utility model is to provide a charging pile fixing base. By setting a positioning ring and multiple sets of positioning pins below the through hole of the base body, after the fixing ring is inserted into the through hole and the positioning ring, multiple sets of positioning pins can be driven to extend into the positioning ring and be inserted into the positioning hole at the bottom of the fixing ring, thereby locking the fixing ring in the positioning ring. At the same time, by setting multiple sets of second studs, U-shaped locking arms and L-shaped locking plates, the multiple sets of U-shaped locking arms can drive the L-shaped locking plates to lock into the grooves on the side of the fixing base, thereby quickly and efficiently fixing the pile body on the base body. Conversely, the multiple sets of positioning pins and L-shaped locking plates can be controlled to simultaneously unlock and delock, so as to quickly remove the pile body.

[0034] The fixing mechanism includes a positioning ring 6 located on the top side of the base body 1 near the through hole 2. A fixing ring 5 can be inserted into the positioning ring 6. The positioning ring 6 has an annular cavity 7 inside. A toothed ring 8 is rotatably installed inside the annular cavity 7. The four ends of the annular cavity 7 near the toothed ring 8 are provided with first studs 10 through bearings. The four ends of the positioning ring 6 are all connected to positioning pins 11 facing the first studs 10. One end of the first stud 10 is fixed with a transmission gear 9 that meshes with the toothed ring 8, and the other end of the first stud 10 is connected to the positioning pin 11 through threads. A limiting component is provided between the positioning pin 11 and the positioning ring 6. The four sides of the bottom end of the fixing ring 5 are provided with positioning holes 12 that match the positioning pins 11.

[0035] A drive motor 17 is fixed on one side of the positioning ring 6. The output end of the drive motor 17 extends into the annular cavity 7 and is provided with a drive gear 18, which meshes with the gear ring 8.

[0036] In use, the fixing seat 4 at the bottom of the pile body 3 can be aligned with the through hole 2 of the base body 1, so that the fixing ring 5 is inserted into the through hole 2 and the positioning ring 6. After the positioning pin 11 is aligned with the positioning hole 12, the drive motor 17 drives the drive gear 18 to rotate, which in turn drives the gear ring 8 to rotate. Then the gear ring 8 can drive multiple transmission gears 9 to rotate simultaneously. After that, the transmission gears 9 drive the first stud 10 to rotate. Under the support and limitation of the limiting component, the first stud 10 can drive the positioning pin 11 to move smoothly in a straight line. Then, multiple sets of positioning pins 11 can simultaneously extend into the positioning ring 6 and be inserted into the positioning hole 12 at the bottom of the fixing ring 5, so that the fixing ring 5 can be locked in the positioning ring 6, thereby realizing the rapid fixing of the pile body 3 on the base body 1.

The four ends of the side of the fixed seat 4 are provided with grooves 23 that match the L-shaped locking plate 21.

[0040] When multiple sets of positioning pins 11 are moved and inserted into the positioning holes 12, the first stud 10 can drive the second stud 19 to rotate, so that the second stud 19 drives the U-shaped locking arm 20 to move on the side of the base body 1. Then the U-shaped locking arm 20 can drive the L-shaped locking plate 21 to move towards the fixed seat 4, so that the L-shaped locking plate 21 is locked on the side of the fixed seat 4 and embedded in the groove 23. Under the clamping of multiple sets of L-shaped locking plates 21, the fixed seat 4 can be further locked on the top of the base body 1.

[0041] With the combined effect of the above structures, the pile body 3 can be quickly and efficiently fixed and installed on the base body 1. Furthermore, by driving the drive gear 18 to rotate in the opposite direction through the drive motor 17, multiple sets of positioning columns 11 and L-shaped clamping plates 21 can be simultaneously unlocked and released, so as to quickly remove the pile body 3. The operation is simple and convenient, and it is easy to disassemble and maintain, which greatly improves the use effect of the fixed base.

[0042] A stop 22 is fixed to one end of the second stud 19 relative to the first stud 10. Based on this, the stop 22 can prevent the bottom end of the U-shaped retaining arm 20 from detaching from the second stud 19.

[0043] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, 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.
