Description

Technical Field

[0001] The utility model relates to the field of automobile charging piles, and more specifically, to an outdoor automobile charging pile. Background Art

[0002] A charging pile is a device that replenishes power for electric vehicles. Its function is similar to that of a gas pump in a gas station. It can be fixed on the ground or on a wall and installed in public buildings (charging stations, shopping malls, public parking lots, etc.) and residential parking lots. It can charge various types of electric vehicles according to the adjusted voltage and current.

[0003] At present, the charging cables connected to the charging heads of the existing charging piles are mostly exposed to the outside and lack the corresponding storage cavity structure, which makes them often easily crushed by cars and affects their service life. In addition, since the charging piles installed outdoors are exposed to the outside, when the outdoor weather temperature is relatively low, the charging cables are often frozen very hard, which makes it inconvenient for users to pull the charging head and charging cable to the car charging port for charging. Therefore, we propose an outdoor car charging pile to solve the above problems. Utility Model Content

[0026] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings of the present invention specification; it is obvious that the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments, and all other embodiments obtained by ordinary technicians in this field without creative work based on the embodiments of the present invention are within the scope of protection of the present invention.

[0027] Embodiment 1:

[0028] See also Figure 1-Figure 5, an outdoor car charging pile, comprising a charging pile box 1, a cable cavity 101 is opened on the top of the charging pile box 1, and the outer side of the cable cavity 101 is rotatably connected to a chamber door through a hinge, a cable winding mechanism 2 is arranged inside the cable cavity 101, a group of mounting rods 3 are fixedly welded on both sides of the inner wall of the cable cavity 101, and a plurality of electric heating rods 4 are fixedly installed between the group of mounting rods 3, and a temperature sensor is also fixedly installed on the top of the inner wall of the cable cavity 101;

[0029] The cable winding mechanism 2 includes a conductive slip ring 5, a winding tube 6 and a rebound box body 7. The bottom of the rebound box body 7 is fixedly installed at the bottom of the inner wall of the cable cavity 101. One end of the winding tube 6 passes through both sides of the rebound box body 7. One end of the winding tube 6 is rotatably connected to the connection between the two sides of the rebound box body 7 through a bearing. A legal strip 701 is sleeved on the outer side of the winding tube 6 located inside the rebound box body 7. One end of the legal strip 701 is clamped with one side of the winding tube 6, and the other end of the legal strip 701 is clamped with the top of the inner wall of the rebound box body 7.

[0030] A gear 8 is fixedly installed on one end of the winding tube 6 located outside the rebound box body 7, and a fastener 9 is clamped on the top of the gear 8. The top of the fastener 9 is rotatably connected to the side of the outer wall of the rebound box body 7 through a pin, and the top of the fastener 9 is also rotatably connected to a pull rod 10. One end of the pull rod 10 passes through the outside of the cable cavity 101. A hanging hole is opened on one side of the top of the fastener 9, and a tension spring 11 is clamped inside the hanging hole. A hanging ring 12 is clamped on the other end of the tension spring 11, and the hanging ring 12 is fixedly welded to one side of the inner wall of the cable cavity 101.

[0031] The operating principle of this outdoor car charging pile is:

[0032] When charging is needed, the user first needs to pull out the pull rod 10 to cause the fastener 9 to disengage from the locking limit between the gear 8. Then the user can hold the charging head 14 and pull the charging cable 13 outward until the length of the pulled charging cable meets the charging requirements. At this time, the charging head 14 can be inserted into the charging socket of the car, and charged by scanning the QR code displayed on the charging pile box 1. After charging is completed, you only need to unplug the charging head 14 first, and then pull the pull rod 10 out again. At this time, the law 701 inside the rebound box body 7 can drive the winding tube 6 to rotate in the opposite direction until the charging cable 13 is completely reeled into the cable cavity 101.

[0033] When the external ambient temperature is low, the charging cable 13 rolled up into the cable cavity 101 stays inside the cable cavity 101, and the electric heating rod 4 starts to heat the inside of the cable cavity 101 to increase the temperature. At the same time, the controller monitors the temperature inside the cable cavity 101 in real time through the temperature sensor, so as to facilitate timely control and stop heating of the electric heating rod 4 when the temperature is too high. In this way, the charging cable 13 can be stored in a relatively high temperature environment to avoid being exposed to the outside and being frozen and hardened, thereby facilitating the later pulling.

[0034] Embodiment 2:

[0035] In view of the above embodiment 1, for further description, refer to Figure 2 and Figure 4 The conductive slip ring 5 includes a stator ring seat 501 fixedly mounted on one side of the inner wall of the cable cavity 101 and a rotor ring seat 502 rotatably connected to the inside of the stator ring seat 501. A power supply cable 503 is fixedly connected to the input terminal inside the stator ring seat 501. The bottom of the power supply cable 503 extends to the inside of the charging pile box 1. The other end of the winding tube 6 is fixedly mounted on the outside of the rotor ring seat 502 by screws, and a through hole 601 is opened on the other end of the winding tube 6. A charging cable 13 is wound on the winding tube 6. One end of the charging cable 13 is fixedly connected to the output terminal inside the rotor ring seat 502 through the through hole 601. The other end of the charging cable 13 penetrates to the outside of the cable cavity 101, and the other end of the charging cable 13 is fixedly connected to the charging head 14. A controller is also fixedly mounted on the top of the inner wall of the cable cavity 101. The controller is connected to a plurality of electric heating rods 4, a temperature sensor and a control mainboard located inside the charging pile box 1 through connecting wires.

[0036] The stator ring seat 501 of the conductive slip ring 5 is convenient for installation, and the rotor ring seat 502 is convenient for connection with the bobbin 6, so that power can be supplied without hindering the normal rotation of the bobbin 6. The specific conductive principle and rotation principle of the conductive slip ring 5 are known public technologies, so they will not be described in detail.

[0037] The above is only a preferred specific implementation of the utility model; however, the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical solution and improved ideas of the utility model within the technical scope disclosed by the utility model, which should be included in the protection scope of the utility model.
