[0042] With the popularization of new energy vehicles, more and more public parking lots will be equipped with charging piles.

[0043] At present, with the increase in the number of vehicles, when there are many vehicles parked in the parking lot, the drivers entering the parking lot cannot quickly confirm which parking spaces are occupied and which parking spaces are equipped with charging piles for charging their vehicles, which brings inconvenience to users.

[0044] Based on the above problems, the present application designs a charging pile and a parking charging system. By arranging a projection device on the main body of the charging pile, the projection device can project guidance information on the vehicle aisle direction corresponding to the target parking space, so as to quickly display the usage of the charging pile in the target parking space through the projected guidance information, thereby facilitating parkers to quickly find parking spaces that can be charged, providing convenience for parkers.

[0045] Based on the above ideas, this application first provides a charging pile, such as Figure 1 As shown, the charging pile includes a charging pile body 10 and a projection device 20 , and the projection device 20 is arranged on the charging pile body 10 .

[0046] The charging pile designed as above can be set in the target parking space A, and specifically can be set around the target parking space. For example, the charging pile can be set at the target position of the target parking space A, and the target position can be where the line of the target parking space A is located. Further, the target position can be where the tail of the vehicle is located when the vehicle is parked in the target parking space A.

[0047] The projection device 20 of the above design can project guidance information to the direction of the vehicle aisle A1 corresponding to the target parking space A, wherein the target parking space A is located between the vehicle aisle A1 corresponding to the target parking space and the charging pile 1. Specifically, Figure 1 As shown, the vehicle aisle is located on the left side of the target parking space, and the charging pile is located on the right side of the target parking space. In this case, the projection device 20 projects the guidance information obliquely, thereby projecting the guidance information to the vehicle aisle. The projected guidance information can display the use of the charging pile of the target parking space, so that the parker can observe the guidance information on the vehicle aisle at a farther distance, and then determine whether the target parking space can be parked and charged according to the guidance information, thereby providing convenience for the parker. Among them, the charging pile body 10 can charge the battery of the new energy vehicle. The charging pile body can be any existing charging pile, for example, a charging pile with a single charging gun, which is connected to the vehicle charging interface through the charging gun, so as to convert the power of the power grid and transmit it to the vehicle.

[0048] The charging pile designed as above, this scheme arranges a projection device on the charging pile body, so that the projection device can project guidance information on the vehicle aisle direction corresponding to the target parking space, thereby quickly displaying the usage of the charging pile in the target parking space through the projected guidance information, thereby facilitating parkers to quickly find parking spaces where they can charge and park, providing convenience for parkers.

[0049] In an optional implementation of this embodiment, as a possible implementation, in order to save the cost of the charging pile, the projection angle of the projection device 20 designed in this solution can be fixed, so that when the charging pile is installed, the staff can adjust the installation angle of the charging pile so that the guidance information projected by the projection device 20 is accurately projected on the vehicle aisle corresponding to the target parking space. Specifically, the projection device 20 designed in this solution can be tilted relative to the horizontal plane (i.e., the ground) where the target parking space is located, and the projection device 20 is fixedly connected to the charging pile body 10, so that the projection device 20 is accurately projected on the vehicle aisle corresponding to the target parking space at a fixed tilt angle.

[0050] In an optional implementation of this embodiment, as another possible implementation, the projection angle of the projection device 20 designed in this solution is adjustable. Specifically, Figure 2 As shown, the charging pile designed in this scheme may also include an adjustment mechanism 30, through which the projection device 20 is connected to the charging pile body 10, and the projection device 20 is tilted relative to the horizontal plane (i.e., the ground) where the target parking space is located, so that after the charging pile is installed, the projection angle of the projection device 20 can be adjusted by the adjustment mechanism 30, so that the guidance information projected by the projection device 20 is accurately projected on the vehicle aisle corresponding to the target parking space. In this case, since the projection angle of the projection device 20 is adjustable, the installation angle is not harsh when the charging pile is installed, thereby improving the installation efficiency of the charging pile. Among them, the adjustment mechanism 30 designed in this scheme can be specifically any mechanism for adjusting the projection angle of the light, such as a pan / tilt, a universal device, and the like.

[0051] In the implementation scheme of the above-mentioned design, the present scheme adjusts the projection angle of the guidance information projected by the projection device 20 by designing an adjustment mechanism 30, so that the guidance information projected by the projection device 20 is accurately projected on the vehicle aisle corresponding to the target parking space, and the projection angle of the projection device 20 is adjustable so that the installation angle of the charging pile is not harsh, thereby improving the installation efficiency of the charging pile.

[0052] In an optional implementation of this embodiment, as a possible implementation, the projection device 20 designed in this solution can adopt a continuous and uninterrupted projection mode, so that when there is no vehicle in the target parking space, the guidance information projected by the projection device 20 passes through the target parking space and is projected on the vehicle aisle corresponding to the target parking space; when there is a vehicle in the target parking space, such as Figure 3 As shown, the guidance information projected by the projection device 20 is projected onto the body of the vehicle parked in the target parking space, so that the guidance information will not exist on the vehicle aisle corresponding to the target parking space due to the shielding of the vehicle body, so that the parker can quickly determine whether the corresponding parking space can be parked and charged by whether there is guidance information on the vehicle aisle.

[0053] In the implementation mode of the above-mentioned design, the projection device 20 is designed to project continuously and uninterruptedly, and the projected guidance information is blocked by the vehicle body on the target parking space, so that the parker can quickly determine whether the corresponding parking space is suitable for parking and charging by whether there is guidance information on the vehicle aisle, thereby saving the device and control logic costs of the charging pile.

[0054] In an optional implementation of this embodiment, in order to make the projection device 20 at a more appropriate height, so that the vehicle in the target parking space can better block the guidance information projected by the projection device 20, such as Figure 4 As shown, the charging pile body 10 designed in this scheme also includes a telescopic mechanism 110. The charging pile can adjust the height of the charging pile body 10 relative to the horizontal plane (i.e., the ground) where the target parking space is located through the telescopic mechanism 110, and then adjust the height of the projection device 20 arranged on the charging pile body 10 relative to the horizontal plane (i.e., the ground) where the target parking space is located, so that the height of the projection device 20 is adjustable, and then when there is a vehicle in the target parking space, it is ensured that the guidance information projected by the projection device 20 is accurately projected onto the body of the vehicle, thereby avoiding the situation where the height of the projection device 20 is too high and the projected guidance information passes over the vehicle and is projected onto the vehicle aisle corresponding to the target parking space.

[0055] In the implementation scheme of the above-mentioned design, the present scheme adjusts the height of the charging pile body 10 relative to the horizontal plane where the target parking space is located through the telescopic mechanism 110, and then adjusts the height of the projection device 20 relative to the horizontal plane where the target parking space is located, so that the height of the projection device 20 is adjustable, and then when there is a vehicle in the target parking space, it is ensured that the guidance information projected by the projection device 20 is accurately projected onto the body of the vehicle.

[0056] In an optional implementation of this embodiment, since different vehicles have different heights, in this case, in order to ensure that there is a vehicle in the target parking space, the guidance information projected by the projection device 20 is accurately projected on the body of the vehicle, as another possible implementation, such as Figure 5 As shown, the charging pile designed in this scheme may also include a first detection device 120, which is arranged on the charging pile body 10, and the first detection device 120 may be electrically connected to the telescopic mechanism 110. The first detection device 120 may be an infrared sensor or other forms of height detection devices, and the telescopic mechanism 110 may be driven by a motor or the like. When the first detection device 120 detects the height of the vehicle, a start signal is sent to the motor, so that the motor drives the telescopic mechanism 110 to telescope and adjust the height.

[0057] In the above embodiment, the first detection device 120 designed in this scheme can detect the height of the vehicle on the target parking space, and control the telescopic mechanism 110 to telescope according to the height of the vehicle on the target parking space, so that the vertical height of the projection device 20 relative to the horizontal plane where the target parking space is located is less than the height of the vehicle on the target parking space, thereby ensuring that when there is a vehicle on the target parking space, the guidance information projected by the projection device 20 is accurately projected on the body of the vehicle. For example, the first detection device 120 detects that there is a vehicle on the target parking space and the height of the vehicle is 170cm. In this case, the first detection device 120 controls the telescopic mechanism 110 to telescope, thereby adjusting the height of the projection device 20 relative to the ground to less than 170cm, for example, to 165cm, so that the guidance information projected by the projection device 20 is accurately projected on the body of the vehicle. For another example, after the previous vehicle in the target parking space has left, a new vehicle parks. The vehicle has a relatively low chassis of only 100 cm. In this case, the first detection device 120 detects that there is a vehicle in the target parking space and that the height of the vehicle is 100 cm. In this case, the first detection device 120 controls the telescopic mechanism 110 to extend and retract, thereby adjusting the height of the projection device 20 relative to the ground to be less than 100 cm, for example, adjusted to 95 cm, so that in the case of vehicles of different heights, the guidance information projected by the projection device 20 can be accurately projected onto the body of the vehicle.

[0058] In the above embodiment, the present scheme detects the height of the vehicle on the target parking space by the first detection device 120, thereby controlling the telescopic mechanism 110 to adjust the vertical height of the projection device relative to the horizontal plane where the target parking space is located, so that the vertical height of the projection device 20 relative to the horizontal plane where the target parking space is located is smaller than the height of the vehicle on the target parking space, and further, in the case of vehicles of different heights, the guidance information projected by the projection device 20 can be accurately projected onto the body of the vehicle, thereby improving the applicability of the guidance information projection.

[0059] In an optional implementation of this embodiment, it is described above that the projection device 20 can continuously and uninterruptedly project the guidance information. As another possible implementation, Figure 6 As shown, the charging pile designed in this solution may further include a second detection device 130 , which is disposed on the charging pile body 10 , and is electrically connected to the projection device 20 .

[0060] In the above implementation, the present solution detects whether there is a vehicle in the target parking space through the second detection device 130, and when a vehicle is detected, controls the projection device 20 to stop projecting the guidance information or change the guidance information. Among them, stopping the projection of the guidance information means that the projection device 20 turns off the projected guidance information, and changing the guidance information means that the projected guidance information is weakened, for example, the brightness of the projected guidance information is lowered, etc.

[0061] In addition, the second detection device 130 can specifically use infrared sensors, radar sensors, etc. to detect whether there is a vehicle in the target parking space through infrared detection, radar detection, etc. The specific detection principle is consistent with the existing principle and will not be repeated here.

[0062] In the above implementation mode, when the second detection device detects that there is a vehicle in the target parking space, the present solution controls the projection device to stop projecting the guidance information or change the guidance information, thereby avoiding the waste of resources and light pollution caused by projection and achieving the effect of saving resources.

[0063] In an optional implementation of this embodiment, the charging pile body 10 designed in this scheme can also be electrically connected to the projection device 20, so that the charging pile body 10 can send a projection change signal to the projection device 20 when it fails to charge, and the projection device 20 projects the changed guidance information in the direction of the vehicle aisle corresponding to the target parking space according to the projection change signal. Among them, the changed guidance information is different from the guidance information before the change in human visual perception, for example, the changed guidance information can be different in shape from the guidance information before the change; for another example, the changed guidance information can be different in color from the guidance information before the change, etc., such as the guidance information before the change can be green guidance information, and the guidance information after the change can be red guidance information.

[0064] In the above-mentioned implementation mode, when the main body of the charging pile fails, this scheme controls the projection device to project the changed guidance information, thereby indicating the charging pile failure of the target parking space through the changed guidance information, thereby avoiding the parker's wrong parking and wasting time, and improving parking convenience.

[0065] In an optional implementation manner of this embodiment, the guidance information described above may include guidance information of any shape and color, for example, Figure 7 As shown, the guidance information may include a guidance arrow pointing to the target parking space. Specifically, the guidance arrow may be any one of a single arrow, multiple arrows, a single row of arrows, or multiple rows of arrows. The color of the arrow in the fault situation may be different from the color of the arrow in the normal working state, so as to distinguish them. For example, the color of the arrow in the fault situation may be as follows: Figure 8 The arrow color is red as shown, and the arrow color under normal working conditions may be green as shown in the figure.

[0066] The present application also provides a parking charging system, such as Figure 8 As shown, the parking charging system includes a plurality of charging piles 1 of any optional embodiment described above.

[0067] The parking charging system designed above includes the charging pile 1 described above. Therefore, the parking charging system designed is provided with a projection device on the charging pile body, so that the projection device can project guidance information on the vehicle aisle direction corresponding to the target parking space, thereby quickly displaying the usage of the charging pile in the target parking space through the projected guidance information, thereby facilitating parkers to quickly find parking spaces where they can charge and park, providing convenience for parkers.
