[0028] Embodiment 1

[0029] like Figure 1-3 As shown, the multifunctional portable DC charging pile proposed by the utility model includes a shell 1 and a charging cable 2 for charging connection arranged thereon, and a handle for conveniently moving the charging pile is arranged on the upper surface of the shell 1. Four support legs 7 for support are arranged at the bottom of the shell 1, and the length of the support legs 7 is slightly greater than the thickness of the bottom box 5. The outer wall of the shell 1 is provided with a clamp 8 for clamping and storing the plug at one end of the charging cable 2. The function of the clamp 8 is to firmly fix the plug at one end of the charging cable 2 to the outer wall of the shell 1, to prevent the charging cable 2 from falling off the support column 4, and to avoid the charging cable 2 from being placed in a mess. The housing 1 is rotatably connected with a storage cover 3 for storing the charging cable 2. The storage cover 3 is provided with a notch 9 corresponding to the charging cable 2 and for the charging cable 2 to be inserted. The outer wall of the housing 1 is provided with a plurality of support columns 4 for saving storage space after the charging cable 2 is wound. The support columns 4 are provided with arc-shaped card slots 41 that can clamp the charging cable 2 and fit closely with the charging cable 2. The arc-shaped card slots 41 present a curved shape that matches the charging cable 2, thereby preventing the charging cable 2 from easily detaching from the support columns 4, so that the charging cable 2 is placed in a disorderly manner in the storage cover 3; the outer wall of the housing 1 is provided with a card block 67, and the card block 67 is provided with a rectangular card slot 68. The inner wall of the storage cover 3 is provided with a switch mechanism corresponding to the card block 67 and capable of clamping the rectangular card slot 68, and the switch mechanism and the card block 67 can be quickly connected or disconnected; the bottom of the housing 1 is provided with an anti-dumping mechanism that prevents it from tipping over or losing stability during use, and the storage cover 3 and the anti-dumping mechanism are opened in linkage to achieve synchronous opening or closing.

[0030] The switch mechanism includes a connecting block 6, which is provided with a rotating groove 61. A pair of support rods 64 are fixedly connected inside the rotating groove 61. The support rod 64 is rotatably connected to a rotating clamping rod 65. One end of the rotating clamping rod 65 is provided with a protrusion that can be inserted into the rectangular clamping groove 68. The pair of rotating clamping rods 65 are provided with a first spring 66 for driving the rotating clamping rod 65 to automatically insert into the rectangular clamping groove 68. The connecting block 6 is movably connected with a pressing rod 62. One end of the pressing rod 62 is fixedly connected with a triangular telescopic block 63 that can resist the rotating clamping rod 65 to rotate and open and make the protrusion at one end of the rotating clamping rod 65 escape from the rectangular clamping groove 68.

[0031] In this embodiment, when a multifunctional portable DC charging pile is needed, such as Figure 2 As shown, first press the pressing rod 62 downward. Figure 3 As shown, the bottom end of the pressing rod 62 drives the triangular telescopic block 63 to move downward. Since the triangular telescopic block 63 is in the shape of a triangle, when the bottom end of the triangular telescopic block 63 abuts against a pair of rotating levers 65, one end of the rotating lever 65 will rotate around the support rod 64. At this time, the other end of the rotating lever 65 will open in the opposite direction, and the protrusion at the other end of the rotating lever 65 will not be able to clamp the rectangular slot 68. Figure 1 As shown, the storage cover 3 can be turned downward to open it, the plug at one end of the charging cable 2 can be taken out from the clamp 8, and then the charging cable 2 wrapped around the support column 4 can be taken out to charge the device; when the multifunctional portable DC charging pile is used up, as shown Figure 1 As shown, the charging cable 2 is wound around the support column 4, and then the plug at one end of the charging cable 2 is inserted into the clamp 8 to fix it, and then the storage cover 3 is rotated upward to first insert the charging cable 2 into the notch 9. Figure 3 As shown, the card block 67 will then be inserted into the rotating groove 61, and at the same time, one end of the rotating card rod 65 is subjected to the elastic pulling force of the first spring 66, so that the protrusion at one end of the rotating card rod 65 is automatically inserted into the rectangular card groove 68 on the card block 67, and the storage cover 3 can be closed, thereby completing the storage of the charging cable 2.

[0032] Embodiment 2

[0033] like Figure 2 and Figure 4As shown, based on the first embodiment, the anti-dumping mechanism of the DC charging pile includes a bottom box 5, a cylinder 51 is arranged inside the bottom box 5, a telescopic slide 53 is slidably connected inside the bottom box 5, one end of the telescopic slide 53 is fixedly connected to the piston rod of the cylinder 51, and the other end of the telescopic slide 53 is convexly provided with a plurality of balls 54 that move more smoothly when in contact with the ground, and a stop block 52 is slidably connected to the bottom box 5, and a convexity at one end of the stop block 52 is fixedly connected to one end of a third spring 56, and the function of the third spring 56 is to drive the stop block 52 to return to its original position. The other end of the third spring 56 is fixedly connected to the inner wall of the bottom box 5, and a contact sensor 57 is arranged inside the bottom box 5, which is electrically connected to the cylinder 51 and can be used for one end of the stop block 52 to resist. The contact sensor 57 is a sensor that can detect and respond to contact with an object. They are usually composed of a mechanical switch or a pressure sensitive element, and when they come into contact with an object, they will generate a specific output signal. The outer wall of the bottom box 5 is fixedly connected to one end of the second spring 55 , and the other end of the second spring 55 is fixedly connected to the outer wall of the storage cover 3 .

[0034] In this embodiment, when preventing the multifunctional portable DC charging pile from tipping over, Figure 2 As shown, when the storage cover 3 is rotated downward to open, the bottom end of the storage cover 3 is subjected to the elastic tension of the second spring 55, so that a large force is required when the storage cover 3 is rotated upward, thereby preventing the charging cable 2 from tipping over to one side. At the same time, when the storage cover 3 is rotated downward, it will abut against one end of the block 52, and the other end of the block 52 will contact the contact sensor 57, and the contact sensor 57 will start and send a signal to the cylinder 51, so that the cylinder 51 is started, and the piston rod of the cylinder 51 pushes one end of the telescopic slide 53 to slide along the inner wall of the bottom box 5, and the ball 54 on the other end of the cylinder 51 contacts the ground and can slide more smoothly. At this time, the telescopic slide 53 will form a vertical angle with the shell 1. When the shell 1 is subjected to external force or pressure, the telescopic slide 53 can balance the direction of the force through the vertical support effect and prevent the structure from tipping over, so that the storage cover 3 and the telescopic slide 53 provide the shell 1 with greater stability and anti-tip ability.
