Description

Technical Field

[0001] The present invention relates to the technical field of automobile charging piles, and in particular to a charging pile for new energy vehicles. Background Art

[0002] The function of a charging pile is similar to that of a gas pump in a gas station. It can be fixed on the ground or on the wall and installed in public buildings (public buildings, shopping malls, public parking lots, etc.) and residential parking lots or charging stations. It can charge various models of electric vehicles according to different voltage levels.

[0003] Most of the leakage accidents of existing charging piles occur at the damaged parts of the charging cables. The charging cables in the existing technology are mostly simply rolled up inside the charging piles. After long-term use, the cable surface is prone to damage. If the cable surface is damaged, after long-term pulling and friction, if the damaged part is not maintained in time, continued use will easily increase the damaged area, resulting in leakage accidents. In view of this, we propose a charging pile for new energy vehicles. Summary of the Invention

[0004] The present invention aims to address the above-mentioned deficiencies in the prior art and provides a charging pile for new energy vehicles, which can promptly detect cable damage and leakage problems and stop the use of the faulty charging pile.

[0005] To achieve the above objectives, the invention provides the following technical solutions:

[0006] A charging pile for new energy vehicles includes a pile body, a display screen, a winding roller, a cable and a charging gun. The cable is installed in the pile body through the winding roller. A placement groove for placing the charging gun is provided on one side of the pile body. A positioning groove is provided in the placement groove. A positioning plate for detecting the placement status of the charging gun is provided in the positioning groove. A sealing plate for closing the placement groove is provided on one side of the placement groove; a wire outlet that cooperates with the cable is provided on one side of the placement groove, and a probe that contacts the cable is installed on one side of the wire outlet through a hose.

[0007] Preferably, a bottom plate for detecting parking of vehicles is provided on the front side of the pile body.

[0008] Preferably, a resettable positioning plate is installed in the positioning groove, and an electromagnet for moving the positioning plate is provided in the positioning groove.

[0009] Preferably, one side of the sealing plate is movably connected to the placement groove through a long axis, and a locking ring is installed in the placement groove through a torsion spring. One end of the locking ring is engaged with the end of the long axis, and the other end is located in the positioning groove and in contact with the positioning plate.

[0010] Preferably, a stop plate is provided on one side of the pile body, and the stop plate cooperates with the sealing plate.

[0011] Preferably, a long groove is provided on one side of the sealing plate, a baffle is installed in the long groove via a spring, and balls are provided on one side of the baffle and one side of the long groove.

[0012] Preferably, a clamping groove is provided on one side of the placement groove, the ball on one side of the baffle cooperates with the clamping groove, and a convex strip is provided on one side of the baffle to facilitate the movement of the baffle.

[0013] Preferably, the device further comprises a controller, wherein the controller is connected to the display screen, the probe, the positioning plate, the electromagnet and the bottom plate respectively.

[0014] Preferably, the charging method further comprises the following steps:

[0015] S1, judging whether there is electricity demand based on user actions;

[0016] S2, if there is a need for charging, charging is carried out;

[0017] S3, when charging is completed and the gun is put away, the cable is charged and the cable is checked for damage;

[0018] S4, checks whether the charging gun is properly placed and gives a voice prompt;

[0019] S5, judging whether to lock the gun according to the detection result of S3.

[0020] Preferably, in the S1, whether to light up the screen is determined based on the information of whether the vehicle arrives when the bottom plate is detected. After the screen is lit, the charging demand is uploaded by scanning the code or swiping the card.

[0021] Compared with the prior art, the beneficial effects of the invention are:

[0022] 1. The present invention has a reasonable structural design and can detect the outside of the cable. When the charging gun is retracted, the cable is charged. The cable cooperates with the probe. If leakage occurs, a loop is formed and the signal is transmitted to the controller, which is convenient for subsequent locking of the gun.

[0023] If the cable is damaged, there is a risk of leakage and the safety of use cannot be guaranteed. At this time, the positioning plate is moved by the electromagnet, causing the charging gun to fall and hit the locking ring, so that it moves to the state where the locking ring locks the long axis. The sealing plate closes the placement slot and the device is in an inactive state.

[0024] 2. The sealing plate of the present invention can seal the placement slot and protect the charging gun; moreover, under the premise that there is no charging demand, it can also prevent the charging gun from being pulled out at will, reducing the probability of damage to the charging gun.

[0025] 3. The present invention detects whether the vehicle has arrived through the bottom plate, which facilitates the subsequent operation of other components; and detects whether the charging gun is placed correctly through the positioning plate, which is conducive to cultivating good usage habits of users and ensuring the smooth locking of the gun in the future.

[0026] 4. The baffle of the present invention is limited in scope by the stop plate during use, but it still meets the requirements of use. The baffle can not only close the placement slot, but also does not affect the movement of the cable. In addition, the ball bearing on the baffle cooperates with the groove in the placement slot to lock the placement slot again. This process does not require much operation and is simple to use.

DETAILED DESCRIPTION

[0039] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0040] Example 1

[0041] A charging pile for new energy vehicles includes a pile body 0, a display screen 2, a winding roller 3, a cable 4 and a charging gun 5, and also includes a controller, which is respectively connected to the display screen 2, a probe, a weight sensor, an electromagnet 65, a weighing sensor, and a contact sensor.

[0042] The charging gun 5 can detect this state after being connected to the car. This function is achieved by a contact sensor on one side of the charging gun 5. The front side of the charging station 0 is equipped with a base plate 1 for detecting vehicle parking. The base plate 1 is equipped with a weight sensor. When the weight sensor changes, it indicates that a car is parked at the charging position.

[0043] The cable 4 is installed in the pile body 0 via the winding roller 3. The winding roller 3 can produce corresponding work according to whether the charging gun 5 is taken out of the positioning groove 62 and whether it is connected to the car.

[0044] When the charging gun 5 is removed, the signal measured by the load cell on the positioning plate 64 changes. The controller activates the take-up roller 3 and unwinds the cable 4, causing the cable 4 to move with the movement of the charging gun 5. When the charging gun 5 is connected to the vehicle, the contact sensor transmits a signal to the controller, causing the take-up roller 3 to stop operating.

[0045] When the charging gun 5 is separated from the car, the reel 3 rotates in the opposite direction to retract the cable 4, and the charging gun 5 moves accordingly. When the charging gun 5 is relocated in the positioning groove 62, the reel 3 stops working.

[0046] A placement groove 61 for placing the charging gun 5 is provided on one side of the pile body 0. A positioning groove 62 is provided in the placement groove 61. A positioning plate 64 for detecting the placement status of the charging gun 5 is provided in the positioning groove 62. A weight sensor is provided on the positioning plate 64.

[0047] A repositionable positioning plate 64 is mounted in the positioning slot 62. One side of the positioning plate 64 is connected to a spring 63. An electromagnet 65 is provided in the positioning slot 62 for moving the positioning plate 64. When the electromagnet 65 is activated, it overcomes the support of the spring 63 and pulls the positioning plate 64 downward, allowing the positioning plate 64 to move into the positioning slot 62.

[0048] One side of the placement slot 61 is provided with an outlet 81 that matches the cable 4. A probe that contacts the cable 4 is installed on one side of the outlet 81 through a hose 82. The end of the probe contacts the cable 4, effectively contacting the damaged area on the outer wall of the cable 4 to form a closed circuit, equivalent to a closed switch, facilitating the controller to detect the signal. Moreover, because the probe is installed through the hose 82, it does not affect the movement of the cable 4 when it is pulled out or retracted.

[0049] A sealing plate 71 is provided on one side of the placement groove 61 to close the placement groove 61. One side of the sealing plate 71 is movably connected to the placement groove 61 through a long axis 72. A locking ring 73 is installed in the placement groove 61 through a torsion spring. One end of the locking ring 73 engages with the end of the long axis 72. In this way, the long axis 72 can be locked. If the long axis 72 cannot rotate, the sealing plate 71 cannot be opened, thereby locking the charging gun 5 in the placement groove 61.

[0050] One end of the locking ring 73 is located in the positioning groove 62 and contacts the positioning plate 64. When the charging gun needs to be locked, the electromagnet 65 is energized, causing the positioning plate 64 to move the charging gun 5 downward. The positioning plate 64 and the charging gun 5 move, causing the locking ring 73 to move from an inclined state to a vertical state until the locking ring 73 fixes one end of the long shaft 72.

[0051] A stop plate 74 is provided on one side of the pile body 0, and the stop plate 74 cooperates with the sealing plate 71. The stop plate 74 is provided at two locations, corresponding to the closed and open states of the sealing plate 71 respectively. When the sealing plate 71 is opened, the sealing plate 71 is rotated counterclockwise until the sealing plate 71 contacts the stop plate 74. At this time, the placement slot 61 is opened, and the charging gun 5 can be taken out. The stop plate 74 limits the rotation range of the sealing plate 71.

[0052] The stop plate 74 on the upper side of the placement slot 61 is tilted and can limit the rotation range of the closing plate 71, but cannot support the closing plate 71 in the opened state. In this way, the closing plate 71 can automatically reset under the action of its gravity, which is convenient for users to use and there is no phenomenon of forgetting to close it.

[0053] A long slot 75 is formed on one side of the sealing plate 71 , and a baffle 76 is installed in the long slot 75 via a spring. The baffle 76 can move into the long slot 75 , and balls 77 are provided on one side of the baffle 76 and one side of the long slot 75 .

[0054] After removing the charging gun 5, the sealing plate 71 is reset. The sealing plate 71 moves downward, causing the baffle 76 to move under the resistance of the cable 4, thereby blocking the placement groove 61. The design of the ball 77 is to reduce the friction between the cable 4 and surrounding components, avoiding unnecessary wear.

[0055] A latching groove 78 is provided on one side of the placement slot 61, and a ball bearing 77 on one side of the baffle 76 engages with the latching groove 78. A ridge 79 is provided on one side of the baffle 76 to facilitate the movement of the baffle 76. When opening the cover 71, press the ridge 79 upward to move it. The ball bearing 77 on the lower side of the baffle 76 will naturally separate from the placement slot 61. Then, the cover 71 is moved counterclockwise, so that the cover 71 no longer seals the placement slot 61. No additional action is required, and this action also opens the placement slot 61, making it convenient to use.

[0056] Before use, set the usage process of the charging pile according to the environment where the charging pile is installed.

[0057] If the charging station is located in a frequently used area, the cover 71 is normally unlocked and locked only when the cable 4 is damaged. If the charging station is located in a less frequently used area, the cover 71 is normally locked to protect the charging gun 5 from unnecessary damage, thus preventing damage to the charging gun 5 by people who do not need to charge the battery.

[0058] During use, the base plate 1 detects the arrival of a vehicle, and the user operates through the display screen 2, then opens the cover 71 and takes out the charging gun 5. When taking it out, first move the charging gun 5 upward so that the lower end of the charging gun 5 is higher than the top surface of the positioning groove 62, and then move the charging gun 5 outward to take it out.

[0059] Connect the charging gun 5 to the car. At this time, the winding roller 3 loosens the cable 4, and the cable 4 moves with the charging gun 5. The charging pile supplies power and starts charging.

[0060] After charging is complete, the charging gun 5 is separated from the vehicle. The cable 4 is still charged, and the reel 3 retracts the cable 4. The cable 4 then passes through the outlet 81. The probe contacts the outer wall of the cable 4 to detect any damage or leakage. If leakage is detected, the sealing plate 71 is reset after the charging gun 5 effectively contacts the positioning plate 64, activating the electromagnet 65. The electromagnet 65 causes the positioning plate 64 to move the charging gun 5, which then presses against the locking ring 73, causing the locking ring 73 to move until it engages with the long shaft 72, locking the sealing plate 71. At this point, the charging gun 5 cannot be removed.

[0061] Example 2

[0062] Also included is a charging method with the following steps,

[0063] S1, determines whether there is a demand for electricity based on the user's actions; in the S1, it is determined whether to light up the screen based on the information of whether the vehicle arrives detected by the bottom plate 1, so as to remind the user of the operation location and also determine whether there is a vehicle parked at the charging location.

[0064] After the screen lights up, the charging request is uploaded by scanning the code or swiping the card. This content is prior art and will not be described in detail in this application. If the user does not perform this action, it means that the user is just stopping and does not need to charge. In this case, the cover 71 does not need to be unlocked in the normally locked state, that is, there is no need to separate the lock ring 73 from the long shaft 72.

[0065] S2, if there is a need for charging, then charge. Open the cover 71, take out the charging gun 5 and connect it to the car, and perform the corresponding charging operation through the display screen 2.

[0066] S3, charging is completed, the cable 4 is charged when the gun is put away, and the cable 4 is detected to see if it is damaged. If the cable 4 is damaged, the probe contacts the cable 4 to form a closed loop, and the signal can be transmitted to the controller so that the gun can be locked after the sealing plate 71 is closed.

[0067] S4: Check whether the charging gun 5 is properly placed. The weight of the charging gun 5 detected by the positioning plate 64 should be within a preset range. If it is not within this range, it means that the charging gun 5 is not properly placed, which may cause damage to the charging gun 5 or cable 4. At this time, a voice prompt is issued to remind the user to put it back in place. The device also includes a voice prompter connected to the controller.

[0068] S5, determine whether to lock the gun based on the detection result of S3. If a leakage signal is detected, the gun is locked after the sealing plate 71 is reset. At this time, a delayed start electromagnet 65 can be set to ensure that the sealing plate 71 is locked when the placement slot 61 is closed.

[0069] After locking the placement slot 61, the display screen 2 displays the usage status and uploads the information that needs to be repaired, which is to remind the user that the charging position cannot be used and to report the repair in time.

[0070] Obviously, those skilled in the art may make various changes and modifications to the present invention without departing from the spirit and scope of the present invention. Thus, if such changes and modifications fall within the scope of the claims and their equivalents, the present invention is intended to include such changes and modifications.
