Description

Technical Field

[0001] This patent relates to the field of charging pile technology, specifically a convenient mobile charging pile. Background Technology

[0002] Charging piles function similarly to gas pumps at gas stations. Common types are fixed to the ground, while others are portable mini-charging piles. These are needed for events held off-site or outdoors where no dedicated charging stations are available. Existing portable charging piles are fixed to transport vehicles using bolts on one side, with the bolt's bottom screwed into the vehicle's bed. As the vehicle moves, the force acting on the charging pile directly impacts the bolts and the threaded grooves of the bed, potentially damaging the bolts and reducing stability over time. Therefore, we propose a more portable charging pile. Utility Model Content

[0003] The purpose of this patent is to provide a convenient and portable charging station to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this patent provides the following technical solution: a portable charging station, comprising a charging box and a fixing plate. The front side of the charging box is provided with a power switch and a charging gun. Rollers are installed at the four corners of the bottom of the charging box. The top left and right sides of the fixing plate are provided with wheel grooves. The bottom ends of the rollers are rolled and installed in the wheel grooves. The top left and right ends of the fixing plate are fixedly installed with internally threaded tubes. The outer shell of the charging box is integrally formed with mounting rings on the left and right sides. Bolts are provided in the mounting rings. The bottom ends of the bolts are screwed into the internally threaded tubes, and the ends of the bolts are pressed against the top of the mounting rings.

[0005] A reinforcing tube is fixedly installed at the top of the internally threaded tube. The bolt includes a circular plate. A vertical rod is integrally formed at the bottom of the circular plate. A threaded rod is integrally formed at the bottom end of the vertical rod. The side wall of the threaded rod is screwed onto the inner side wall of the internally threaded tube. The outer side wall of the vertical rod is in contact with and fits against the inner side wall of the reinforcing tube.

[0006] Preferably, a slot is provided on the lower right side of the side wall of the upright, and a circular groove is provided on the right side of the inner side wall of the mounting ring. A spring is fixedly installed on the inner right side wall of the circular groove, and a positioning post is fixedly installed on the left end of the spring. The side wall of the positioning post slides against the inner side wall of the circular groove. The left end of the positioning post is provided with a spherical surface, and the left end of the spherical surface is tightly fitted against the side wall of the upright. The spherical surface matches the internal shape of the slot.

[0007] Preferably, the top of the circular plate is integrally formed with a cross block.

[0008] Preferably, a label is provided at the top right end of the circular plate, and the label is located on the upper side of the circular groove.

[0009] Preferably, the diameter of the threaded rod is smaller than the inner diameter of the reinforcing tube.

[0010] Preferably, the fixing plate has mounting holes at the four corners of its top, and mounting bolts are installed in the mounting holes.

[0011] Compared with the prior art, the beneficial effects of this patent are as follows: This patent provides wheel grooves on both the top left and right sides of the fixed plate, and installs rollers on the bottom of the charging box. The rollers roll in the wheel grooves. The bolts on the side of the charging box are composed of a round plate, a vertical rod, and a threaded rod. A reinforcing tube is installed at the top of the internal threaded tube. After the threaded rod is screwed into the internal threaded tube, the side wall of the vertical rod will also be in contact with the inner side wall of the reinforcing tube. This disperses the force acting on the threaded rod to the vertical rod and the reinforcing tube, increases the stress range of the overall bolts, increases the compressive strength, and improves the overall stability of the charging pile.

Detailed Implementation

[0016] The technical solutions of this patent embodiment will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this patent, and not all of them. Based on the embodiments of this patent, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this patent.

[0017] Please see Figure 1 , Figure 2 and Figure 3This patent provides a technical solution: a convenient mobile charging pile, including a charging box 1 and a fixing plate 6. The front side of the charging box 1 is provided with a power switch 3 and a charging gun 4. Rollers 5 are installed at the four corners of the bottom of the charging box 1. The top left and right sides of the fixing plate 6 are provided with wheel grooves 7. The bottom ends of the rollers 5 are rolled in the wheel grooves 7. The top left and right ends of the fixing plate 6 are fixedly installed with internal threaded tubes 8. The outer shell of the charging box 1 is integrally formed with mounting rings 9 on the left and right sides. The mounting rings 9 are provided with bolts 10. The bottom ends of the bolts 10 are screwed into the internal threaded tubes 8, and the ends of the bolts 10 are pressed against the top of the mounting rings 9.

[0018] The charging box 1 has the model number 1ZD40-2-B and can be used for various vehicle models that need to be charged.

[0019] A reinforcing tube 11 is fixedly installed at the top of the internally threaded tube 8. The bolt 10 includes a circular plate 12. A vertical rod 13 is integrally formed at the bottom of the circular plate 12. A threaded rod 14 is integrally formed at the bottom end of the vertical rod 13. The side wall of the threaded rod 14 is screwed onto the inner side wall of the internally threaded tube 8. The outer side wall of the vertical rod 13 is in contact with the inner side wall of the reinforcing tube 11.

[0020] If the threaded rod 14 is simply screwed into the internal threaded tube 8 without the reinforcing tube 11, most of the shaking force acting on the charging box 1 will be applied to the threaded rod 14, potentially causing the threaded rod 14 to break.

[0021] By having the outer wall of the upright 13 and the inner wall of the reinforcing tube 11 in relative contact and fit, the force acting on the threaded rod 14 is distributed to the upright 13 and the reinforcing tube 11, thereby increasing the stress range of the overall bolt 10, increasing the compressive strength, and improving the overall stability of the charging pile.

[0022] Specifically, a slot 15 is provided on the lower right side of the side wall of the upright 13, and a circular groove 16 is provided on the right side of the inner side wall of the mounting ring 9. A spring 17 is fixedly installed on the inner right side wall of the circular groove 16, and a positioning post 18 is fixedly installed on the left end of the spring 17. The side wall of the positioning post 18 slides against the inner side wall of the circular groove 16. A spherical surface 19 is provided on the left end of the positioning post 18. The left end of the spherical surface 19 fits tightly against the side wall of the upright 13, and the spherical surface 19 matches the internal shape of the slot 15.

[0023] Figure 3 The spring 17 shown is in a compressed state.

[0024] When the charging box 1 is needed, rotate the circular plate 12 to move the threaded rod 14 upward and disengage it from the internal threaded tube 8. Then move the circular plate 12 upward. When the slot 15 moves to the position of the spherical surface 19, the spherical surface 19 can be inserted into the slot 15 by the rebound effect of the spring 17. At this time, the position of the bolt 10 can be positioned, and the bottom height of the threaded rod 14 is higher than the top height of the reinforcing tube 11. After the charging box 1 is used, move the charging box 1 to the fixing plate 6, and the threaded rod 14 can be moved directly to the upper side of the reinforcing tube 11.

[0025] Specifically, the top of the circular plate 12 is integrally formed with a cross block 20.

[0026] The cross block 20 allows for easy rotation of the circular plate 12.

[0027] Specifically, a label 21 is provided at the top right end of the circular plate 12, and the label 21 is located on the upper side of the circular groove 16.

[0028] The label 21 is set to calibrate the position of the slot 15 and the circular groove 16 when the upright 13 is moved upward.

[0029] Specifically, the diameter of the threaded rod 14 is smaller than the inner diameter of the reinforcing tube 11.

[0030] By making the diameter of the threaded rod 14 smaller than the inner diameter of the reinforcing tube 11, the threaded sidewall of the threaded rod 14 can be prevented from contacting the inner sidewall of the reinforcing tube 11 during up-and-down movement, thus avoiding thread wear.

[0031] Specifically, mounting holes are provided at the four corners of the top of the fixing plate 6, and mounting bolts 2 are installed in the mounting holes.

[0032] The fixing plate 6 can be fixed inside the truck bed of the transport vehicle by mounting bolt 2.

[0033] Working principle: When the charging box 1 is needed, the circular plate 12 can be rotated to move the threaded rod 14 upward and disengage it from the internal threaded tube 8. Then, the circular plate 12 is moved upward. When the slot 15 moves to the position of the spherical surface 19, the spherical surface 19 can be inserted into the slot 15 by the rebound effect of the spring 17. At this time, the position of the bolt 10 can be positioned, and the bottom height of the threaded rod 14 is higher than the top height of the reinforcing tube 11. Then, the charging box 1 can be removed from the truck bed.
