Technical Field

[0001] The utility model relates to the field of charging piles, in particular to a charging pile capable of protecting a charging cable. Background Art

[0002] Usually, when using a charging pile to charge a new energy vehicle, a charging cable of a certain length is required to connect the charging pile to the new energy vehicle. However, after charging is completed, most people directly put the charging gun back to grab the charging gun seat without considering the charging cable. That is, after charging is completed, most of the charging cables are directly dragged on the ground and in contact with the ground. Not only will pedestrians and cars passing by easily crush the charging cables and cause damage, but when it rains, the cables dragged on the ground will be soaked in rainwater, which will cause certain safety hazards and equipment damage in the long term. Even though there is currently a hook method to wrap the charging cable around the charging box or charging gun, on the one hand, the owner and other users need to do the winding work after charging is completed, which causes inconvenience; on the other hand, some users still cannot avoid part of the charging cable dragging on the ground. Therefore, it is necessary to improve the existing technology and provide a charging pile that can reel in the charging cable after charging is completed to prevent it from dragging on the ground and protect it.

[0029] The present invention will be further described below with reference to the accompanying drawings.

[0030] It should be noted that the left and right directions in the following embodiments refer to the attached Figure 2 The X arrow in the image points in the direction of the image.

[0031] Example 1: Reference Figures 1 to 5 The charging pile shown can protect the charging cable, and includes a charging box 1, to which a charging cable 4 and a power cable are connected. The input end of the charging cable 4 is connected to the charging box 1, and the output end thereof is connected to the charging gun 3. The input end of the power cable is connected to the power supply, and the output end thereof is connected to the charging box 3. The charging pile also includes:

[0032] The L-shaped box 2 is located above the charging box 1 and includes a vertical box 21. A horizontal box 22 is provided on the side of the vertical box 21, and the first box cavity of the horizontal box 22 is opened at the bottom. In this embodiment, the horizontal box faces to the right, and the gun seat of the charging gun is installed on the front panel of the charging box, so as to avoid the influence of the horizontal box on the charging operation.

[0033] The winch mechanism includes a winch 5, which is connected to a motor 6. The winch 5 retracts and extends the charging cable 4 under the drive of the motor. The motor is a bidirectional rotating motor. The winch is connected to the drive shaft of the motor. The winch is driven by the motor to rotate to retract and extend the charging cable 4. The charging cable is partially wound on the winch 5.

[0034] The sensing mechanism includes a first detection component, which includes a first sensor 9 . The first sensor 9 is used to sense the position of the charging gun 3 .

[0035] In this embodiment, the first detection assembly includes a mounting plate, to which the first sensor is mounted. The mounting plate is mounted near the charging gun's base. The first sensor 9 is a first photoelectric sensor. As shown in the figure, the mounting plate is mounted above the charging gun's base, and the first photoelectric sensor is mounted on the bottom surface of the mounting plate, positioned to sense the charging gun. Alternatively, the mounting plate can be mounted below the base, with the first photoelectric sensor mounted on the top surface of the mounting plate; or the mounting plate can be mounted to the left or right side of the base, with the first photoelectric sensor mounted facing the base.

[0036] The charging box 1 is provided with a control box 8, and the control box 8 is provided with a controller. The controller is connected to the sensing mechanism and the winch mechanism. The controller controls the winch mechanism according to the signal feedback from the reaction mechanism. The control chip can be a control chip or a single chip microcomputer.

[0037] Specifically, the signal input end of the controller is connected to the signal output end of the first sensor, and the signal output end of the controller is connected to the signal input end of the motor 6; the connection between the upper controller and the first sensor and the motor can be an electrical connection or a wireless signal transmission connection, preferably, a wireless signal transmission connection, and the wireless signal transmission connection can be a Bluetooth connection or a WIFI connection.

[0038] The sensing mechanism further includes a second detection component, which includes a second sensor 110. The controller controls the motor of the winch mechanism to shut down according to the detection signal of the second sensor.

[0039] Specifically, the signal input end of the controller is connected to the signal output end of the second sensor. As above, the connection between the controller and the second sensor can be an electrical connection or a wireless signal transmission connection, preferably a wireless signal transmission connection.

[0040] In this embodiment, the second sensor 110 is mounted on the charging cable 4 near the charging gun; the second sensor 112 is a tension sensor. The second detection assembly comprises an upper plate 111 and a lower plate 113. The charging cable 4 is fixedly threaded through the upper and lower plates 111 and 113. For example, the charging cable can be threaded through the upper or lower plate and fixedly connected to the threaded hole by filling it with insulating adhesive. The upper and lower plates are made of wood, but other materials such as rubber or plastic are also acceptable. The tension sensor is connected to the upper and lower plates 111 and 113 at both ends, and the tension sensor is mounted using conventional techniques. Specifically, in another embodiment, the charging cable between the upper and lower plates has a margin so that it will not be stretched while the other charging cables are being reeled into place by the winch (i.e., when the control motor is shut down). In this embodiment, the tension sensor can be an S tension sensor, but there is no upper limit on its selection.

[0041] Specifically, a control button 100 is provided on the charging box or the transverse box 22 to control the rotation of the motor. The conventional technology for controlling the forward and reverse rotation of the motor and its start and stop is not described here. Alternatively, a control panel is provided on the charging box to control the start and stop of the motor, which is also a known technology.

[0042] There may be another embodiment in which guide wheels (not shown) may be suitably installed above the charging box or on the vertical box or the horizontal box, and the charging cable may be suitably wound around the guide wheels. This is a well-known technology and will not be described in detail here.

[0043] When the utility model is implemented, Figure 1 As shown, before charging, the user unplugs the charging gun from the gun holder until it is out of the detection range of the first photoelectric sensor. The controller controls the rotation of the motor according to the signal fed back by the first photoelectric sensor (the charging gun changes from being present to not present), so that the charging cable is released from the winch. After it is released to the appropriate length, the motor is turned off by the control button, and then charging can be carried out. Alternatively, the motor can be turned on by the control button first, and then the charging gun can be unplugged from the gun holder. After the charging cable is released to the appropriate length, the motor can be turned off by the control button, and then charging can be carried out.

[0044] After charging is complete, the charging cable is returned to the charging cable holder. During this process, when the charging cable is within the detection range of the first photoelectric sensor, the controller controls the motor to rotate based on the signal fed back by the first photoelectric sensor (the charging cable goes from no to present), causing the winch to reel in the charging cable. During this process, the winch continuously reduces the portion of the charging cable dragging on the ground by reeling in the charging cable. During this process, the tension sensed by the tension sensor does not change much (the sensed tension at this time is mainly caused by the weight of the charging cable from the lower plate to the ground). Until the charging cable is completely free of the ground, the winch continues to reel in the charging cable, and the tension sensed by the tension sensor continuously decreases (due to the decreasing weight of the charging cable between the lower plate and the fold) until it reaches a set value. At this point, the charging cable in the front and rear portions of the upper and lower plates is in a drooping state. The controller controls the motor to shut down based on the signal fed back by the tension sensor. The charging cable is now reeled in by the winch, thus automatically reeling in the charging cable after charging, preventing it from dragging on the ground and protecting it.

[0045] Compared with manually controlling the winch to reel in the charging cable after charging, the utility model can avoid the user forgetting to operate due to anxiety or unfamiliarity, and the utility model is more convenient.

[0046] Example 2: Reference Figure 6 The charging pile shown in the figure can protect the charging cable. Compared with the first embodiment, the transverse box in this embodiment faces forward. The second detection component is different from the first embodiment.

[0047] The height of the transverse box is above 1.6 m.

[0048] Specifically, in this embodiment, the second detection assembly includes a second sensor 110 and a sensing block 114. The second sensor 110 includes at least two second photoelectric sensors 115. Multiple second photoelectric sensors are provided to better identify and detect the sensing block. The second photoelectric sensors 115 are mounted on the front panel of the vertical box 21.

[0049] The charging cable passes through a sensing block 114 at a certain distance from the charging gun, and the second photoelectric sensor 115 identifies and detects the sensing block 114. The number of second photoelectric sensors 115 allows the sensing block to sense and identify the sensing block when it passes through the vertical box at the installation height of the second photoelectric sensor.

[0050] Specifically, the sensing block 114 may be a wooden block, and after the charging cable passes through the sensing block, an insulating adhesive is filled in the passing hole.

[0051] In specific applications of this embodiment, the user pulls the charging gun from the gun holder until it is out of the detection range of the first photoelectric sensor. The controller then controls the rotation of the motor based on the signal fed back by the first photoelectric sensor (the charging gun changes from being present to not present), so that the charging cable is released from the winch. After it is released to an appropriate length, the motor is turned off by pressing the control button, and then charging can be carried out. Alternatively, the motor can be turned on by pressing the control button first, and then the charging gun can be pulled out of the gun holder. After the charging cable is released to an appropriate length, the motor can be turned off by pressing the control button, and then charging can be carried out.

[0052] After charging is completed, the charging gun is put back into the gun seat. During this process, when the charging gun is within the detection range of the first photoelectric sensor, the controller controls the motor to rotate according to the signal feedback from the first photoelectric sensor (the charging gun is from nothing to something), so that the winch reels in the charging cable until the induction block is continuously lifted as the winch reels in the charging cable, until it is pulled high enough to be recognized by the second photoelectric sensor. The controller controls the motor to shut down according to the signal feedback from the second photoelectric sensor. At this time, the charging cable is reeled into place by the winch, thereby realizing automatic reeling of the charging cable after charging, avoiding the charging cable dragging on the ground after charging, and protecting it.

[0053] Example 3: Compared with Example 1 or Example 2, the first sensor 9 in this example is a pressure sensor, which is installed in the socket of the gun holder of the charging gun. Specifically, the pressure sensor is installed on the side wall of the socket of the gun holder of the charging gun.

[0054] In this embodiment, the controller controls the motor according to changes in the signal from the pressure sensor.

[0055] Specifically, during charging, after the charging gun is unplugged from the socket of the gun holder, the pressure detected by the pressure sensor becomes 0, and the controller controls the rotation of the motor according to the signal feedback from the pressure sensor, so that the charging cable is released from the winch. After it is released to the appropriate length, the motor is turned off by the control button, and then charging can be carried out; or the motor can be turned on first by the control button, and then the charging gun can be unplugged from the gun holder. After the charging cable is released to the appropriate length, the motor can be turned off by the control button, and then charging can be carried out.

[0056] After charging is completed, the charging gun is returned to the gun seat, and the pressure detected by the pressure sensor increases. The controller controls the rotation of the motor according to the signal fed back by the pressure sensor, so that the winch reels in the charging cable until the induction block is continuously lifted as the winch reels in the charging cable. Then, as in Example 1 or Example 2, the controller controls the motor to shut down through the feedback signal of the second detection component.

[0057] Example 4: This example, based on any of Examples 1 through 3, further includes a photovoltaic power generation assembly. The photovoltaic charging assembly includes a photovoltaic panel 7 and a battery. The battery provides power for the controller, the first detection assembly, the second detection assembly, and the winch mechanism. The photovoltaic panel 7 is mounted on the upper panels of the vertical and horizontal boxes. The photovoltaic panel and battery are connected via an MPPT controller. Using a battery to store electricity using a photovoltaic panel is a mature technology and will not be described in detail here.

[0058] The above description of the present invention and its embodiments is non-limiting. The drawings show only one embodiment of the present invention, and the actual structure is not limited thereto. In short, if a person skilled in the art is inspired by the above, and does not deviate from the purpose of the present invention, without inventive design, a structure and embodiment similar to the technical solution should fall within the scope of protection of the present invention.
