DETAILED DESCRIPTION

[0029] The following is a detailed description of a soft ferrite core for a new energy vehicle charging pile provided by the utility model in combination with the accompanying drawings and specific embodiments. At the same time, it is explained here that in order to make the embodiments more detailed, the following embodiments are the best and preferred embodiments, and those skilled in the art may also adopt other alternative methods to implement some known technologies; and the accompanying drawings are only for a more specific description of the embodiments, and are not intended to specifically limit the utility model.

[0030] like Figure 1-Figure 4 As shown, the embodiment of the utility model provides a soft ferrite core for a new energy vehicle charging pile, comprising a core body 1

[0031] and an installation frame 2, the core body 1 and the installation frame 2 are each provided with two, the installation frame 2 is a U-shaped block structure, and the ring hoop is on the outer wall of the core body 1. When assembled, the two core bodies 1 are symmetrically attached to each other, and the two installation frames 2 cooperate with each other to form a U-shaped frame structure hooped on the periphery of the two core bodies 1; the magnetic core adopts a PQ type power magnetic core.

[0032] The self-locking member 3 is movably connected with the side of the installation frame 2. The self-locking member 3 includes a slider 31 and a locking hook 33. The locking hook 33 is fixedly connected to the slider 31 through a long rod 32. When assembled, the hook bodies of the two locking hooks 33 on the same side are arranged back to back.

[0033] The locking plate 4 has locking holes 41 symmetrically formed at both ends thereof. When assembled, the two locking holes 41 respectively cooperate with the two locking hooks 33 located on the same side of the two mounting frames 2 to engage with each other. The size of the locking hole 41 is slightly larger than the size of the locking hook 33, and when engaged, the side wall of one side of the locking hole 41 slides into the U-shaped hook groove of the locking hook 33.

[0034] The self-locking member 3 and the locking sheet 4 cooperate with each other to lock the sides of the two installation frames 2, so that the two installation frames 2 are tightly fitted to each other to form a frame-shaped structure hoop around the outer side of the magnetic core body 1, so that the two magnetic core bodies 1 are tightly fitted to each other to complete the assembly.

[0035] like Figure 2 As shown, the outer side walls of both sides of the installation frame 2 are symmetrically provided with slide grooves 21, which are semi-open and extend to the top of the side of the installation frame 2, and are slidably connected with the slider 31, the long rod 32, and the lock hook 33.

[0036] By providing a slide groove 21 to cooperate with the sliding of the slider 31, the long rod 32, and the locking hook 33, the linear sliding of the locking hook 33 is ensured during assembly, which facilitates its alignment with the locking hole 41. At the same time, the slider 31, the long rod 32, and the locking hook 33 all slide inside the slide groove 21, thereby reducing the side protruding height of the installation frame 2 and reducing the probability of damage to the self-locking part 3 due to collision during transportation.

[0037] like Figure 3 As shown, inner cavities 22 are provided inside both side edges of the mounting frame 2, and the inner cavity 22 is connected to the slide groove 21 located on the same side through a through groove 23, wherein the radial cross-section of the inner cavity 22 is circular, and the through groove 23 connects the slide groove 21 and the upper half of the inner cavity 22, thereby improving the side structural strength of the mounting frame 2.

[0038] like Figure 4 As shown, the self-locking member 3 also includes a sliding sleeve 35, which is in a circular ring structure and is connected to the back side of the slider 31 through a connecting rod 34. The outer wall of the connecting rod 34 is slidably connected to the inner wall of the inner cavity 22, and the connecting rod 34 is slidably connected to the through groove 23.

[0039] The sliding sleeve 35 is provided to be slidably connected with the inner cavity 22 and moves synchronously with the slider 31 when sliding in the slide groove 21 , thereby improving the smoothness of the self-locking member 3 when sliding.

[0040] like Figure 3 As shown, a slide rod 5 is provided inside the inner cavity 22 . The slide rod 5 is in a cylindrical rod-shaped structure and is fixedly connected to the two end walls of the inner cavity 22 . The slide rod 5 is slidably connected with the inner wall of the sliding sleeve 35 .

[0041] The sliding rod 5 is provided to further guide the sliding of the self-locking member 3, thereby improving the linearity of its sliding motion and preventing the spring 6 from bending during deformation, thereby increasing the service life of the device.

[0042] like Figure 3 As shown, a spring 6 is sleeved on the body of the slide rod 5, and two ends of the spring 6 are in close contact with the bottom of the slide sleeve 35 and the bottom wall of the inner cavity 22 respectively.

[0043] By providing a spring 6 to apply elastic force and continuously press the sliding sleeve 35, the two self-locking parts 3 on the same side tend to move relative to each other. At this time, under the limiting action of the locking plate 4, the two installation frames 2 tend to move toward each other through relative force, so that the two installation frames 2 fit tightly together, realizing the hoop effect on the magnetic core body 1.

[0044] like Figure 4 As shown, the self-locking member 3 further includes a paddle 36 , which is an arc-shaped protruding structure, fixedly connected to the front side of the slider 31 , and the inner concave surface of the paddle 36 faces the end away from the locking hook 33 .

[0045] By providing the paddle 36 , when disassembling, the paddles 36 on the two self-locking members 3 on the same side can be pressed with fingers to resist the elastic force of the spring 6 , so that the two locking hooks 33 approach each other, thereby disconnecting the locking hole 41 .

[0046] like Figure 2 As shown, a boss 42 is fixedly connected to the center of the locking piece 4, so that when the locking hook 33 is disconnected from the locking hole 41, the locking piece 4 can be pulled out by grabbing the boss 42 to complete the disassembly.

[0047] Working principle:

[0048] During assembly, the two magnetic core bodies 1 are symmetrically fitted together, and the two mounting frames 2 are respectively hooped on the back sides of the two magnetic core bodies 1, and the two paddles 36 on the same side are pressed so that the spacing between the two locking hooks 33 is the same as the spacing between the two locking holes 41 on the locking plate 4, and then the two locking holes 41 on the locking plate 4 are aligned and engaged with the locking hooks 33, and the paddles 36 are released. Under the elastic force of the spring 6, the groove of the paddle 36 is engaged with the side wall of the locking hole 41, and the mounting frame 2 is pushed under the reaction force, so that the two mounting frames 2 fit together to hoop the magnetic core body 1, and the assembly is completed.

[0049] During disassembly, the two paddles 36 on the same side are pressed to disconnect the locking hook 33 from the locking hole 41 , and the locking piece 4 is pulled out by grabbing the boss 42 to realize the disassembly of the two installation frames 2 .

[0050] The present invention covers any substitution, modification, equivalent method and scheme made on the essence and scope of the present invention. In order to make the public have a thorough understanding of the present invention, specific details are described in detail in the above preferred embodiments of the present invention, and those skilled in the art can fully understand the present invention without the description of these details. In addition, in order to avoid unnecessary confusion about the essence of the present invention, well-known methods, processes, procedures, components and circuits are not described in detail.

[0051] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the present invention. These improvements and modifications should also be regarded as the protection scope of the present invention.
