[0002] With the continuous development of new energy technology and battery technology, electric equipment will continue to develop and become more popular. At present, during the fully automatic charging process of new energy vehicles, after the robot car runs to the vicinity of the parking space (charging site), the robot cannot drive in due to the narrow space between the two parking spaces. In addition, the arm span of the robotic arms in the existing market is generally short, and the robotic arms are not flexible enough, making it difficult to complete the charging plug-in and unplugging actions. In addition, the location where the owner parks the car generally forms various angles with the robotic arm, which will cause great difficulties for the automatic charging function of the robot car, resulting in the robotic arm being unable to complete the plug-in and unplugging actions, and thus unable to complete the charging action. Or when the car is waiting for the charging device, the charging port cover of the car's charging interface may close automatically or accidentally, resulting in the robot being unable to complete charging. Summary of the Invention

[0003] The purpose of the present invention is to provide an adapter device, a charging site and a method for using the adapter device, so that the charging connection port of each parking space can maintain a unified direction, simplifying the charging action of the robot, and making the charging action of the robot unaffected by the owner's parking location, the location of the charging interface and whether the car charging interface will close automatically or accidentally, so as to solve the technical problem that the charging robot has difficulty completing the charging action during fully automatic charging.

[0004] In order to solve the above technical problems, the specific technical solutions of the present invention are as follows:

[0005] The adapter device includes a positioning pile and a connecting line. The positioning pile is connected to the connecting line. At least a single connecting line is connected to a single positioning pile. The connecting line includes a line body, a charging connection port and a power supply connection port.

[0006] Furthermore, the positioning pile includes a rod body and a support base, and the rod body is connected to the support base.

[0007] Furthermore, the connection between the rod body and the support base includes a movable connection.

[0008] Furthermore, the support base includes a base body, a conversion assembly and a buffer assembly. The base body is connected to the conversion assembly, and the base body is connected to the buffer assembly.

[0009] Furthermore, the conversion assembly includes a rotating shaft, a gear and a rack, the rotating shaft is connected to the gear, the gear and the rack cooperate, the gear and the rack are connected, the rotating shaft is connected to the side wall of the base, the rack is connected to the bottom plate of the base, and the rotating shaft is connected to the rod body.

[0010] Furthermore, the support base also includes a locking assembly, which includes a stop shaft and a pedal. The stop shaft is used to limit the movement of the rod body, the stop shaft is connected to the side wall of the base, and the pedal is movably connected to the bottom plate of the base.

[0011] The charging site includes the switching device.

[0012] The method for using the adapter includes the following steps:

[0013] Step S1: Park the device to be charged in the charging area; insert the charging connector on the connecting cable into the rod of the adapter;

[0014] Step S2: Connect the power supply connector on the connecting cable to the charging port of the device to be charged;

DETAILED DESCRIPTION

[0029] 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.

[0030] In the present invention, unless otherwise expressly specified or limited, the terms "mounted," "connected," "connect," "fixed," etc. should be understood broadly. For example, they may refer to fixed connection, detachable connection, or integration; mechanical connection or electrical connection; direct connection or indirect connection through an intermediate medium; internal communication between two components or interaction between two components. Those skilled in the art will understand the specific meanings of the above terms in the present invention based on specific circumstances.

[0031] Switching devices, such as Figure 1 As shown, the robot includes a positioning post and a connecting line. The positioning post is connected to the connecting line, and the connection between the positioning post and the connecting line includes a detachable connection. Each positioning post is connected to at least one connecting line, which includes a cable body 32, a charging connector 31, and a power connector 33. The charging connector 31 is connected to the cable body 32, and the power connector 33 is connected to the cable body 32. Preferably, the positioning post is connected to the connecting line via the charging connector 31. The connecting line is used to extend the charging port of the device to be charged. The positioning post is used to move the extended charging ports of the device to be charged at different locations to a fixed position, facilitating charging of the robot, simplifying the fully automatic charging process and reducing the difficulty of fully automatic charging technology. During use, the power connector 33 on the connecting line must first be connected to the charging port of the device to be charged. At this time, if the charging port cover is closed, the cable body 32 or the power connector 33 can lock the charging port cover of the vehicle, preventing the charging port cover from completely closing while the vehicle is waiting for the power supply, and thus preventing the robot from charging. The charging connection port 31 is used to connect to a power supply device, and the power supply connection port 33 is used to connect to a device to be charged.

[0032] An indicator light is provided on the connecting line. Preferably, the indicator light is provided on the charging connecting port 31. The indicator light is electrically connected to the power supply connecting port 33. The indicator light is used to indicate whether the charging connecting port 31 is successfully connected to the charging interface of the device to be charged, and can also verify whether the connecting line is damaged.

[0033] The positioning pile includes a rod body 2 and a support base, wherein the rod body 2 is cooperatively connected to the support base. Preferably, the connection between the rod body 2 and the support base includes a movable connection, so that the rod body 2 can be laid down, thereby preventing the owner from accidentally hitting the rod body 2 when parking the car, thereby improving the safety of the product during use.

[0034] like Figures 2 to 4 As shown, the support base includes a base body, a conversion assembly, and a buffer assembly. The base body is connected to the conversion assembly, and the base body is connected to the buffer assembly. The base body includes a base bottom plate 111 and a base side wall 112, and the base bottom plate 111 is connected to the base side wall 112. The base bottom plate 111 and the base side wall 112 can be an integrated structure or a split structure. Preferably, the base body and the buffer assembly are detachably connected, so that the device can obtain different falling speeds to be buffered by replacing the buffer assembly.

[0035] The conversion assembly includes a rotating shaft 122, a gear 121, and a rack 123. The rotating shaft 122 is connected to the gear 121, the gear 121 cooperates with the rack 123, the gear 121 and the rack 123 are connected, the rotating shaft 122 is connected to the base side wall 112, and the connection between the rotating shaft 122 and the base side wall 112 includes a movable connection. The rack 123 is connected to the base bottom plate 111, and the rotating shaft 122 is connected to the rod body 2. The conversion assembly is used to convert the rotational force into a horizontal force to facilitate the buffer assembly to perform buffering.

[0036] The buffer assembly includes a buffer spring 132 and a connector 131. The buffer spring 132 is connected to the connector 131 and includes a compression spring. The rack 123 is connected to one end of the buffer spring 132 via the connector 131. Preferably, the rack 123 and the connector 131 are connected via a fastener. The other end of the buffer spring 132 is connected to the base side wall 112. Optionally, the buffer spring 132 is also connected to the base side wall 112 via the connector 131. Preferably, a limiter 133 is further provided on the base side wall 112. The limiter 133 is used to limit the radial movement of the buffer spring 132, and the buffer spring 132 surrounds the limiter 133. The connection method between the buffer spring 132 and the base side wall 112 includes a detachable connection, so that the buffer spring 132 can be replaced as needed. The buffer spring 132 can select an appropriate material and compression amount of the buffer spring 132 according to the weight of the rod body 2, thereby controlling the speed at which the rod body 2 falls.

[0037] A limiting portion 114 is provided on the base bottom plate 111, and the limiting portion 114 is used to limit the radial movement of the rack 123. The spacing of the limiting portions 114 is slightly larger than the width of the rack 123. Preferably, a slider 113 is also provided on the base bottom plate 111, and the slider 113 is arranged in the limiting portion 114. The slider 113 is fixedly connected to the base bottom plate 111, and the slider 113 is connected to the limiting portion 114. The width of the slider 113 is less than or equal to the spacing of the limiting portions 114. The rack 123 is connected to the base bottom plate 111 through the slider 113. When the slider 113 is damaged due to long-term wear or the rack 123 cannot be closely matched with the gear 121, the slider 113 can be directly replaced to extend the service life of the device and save usage costs.

[0038] Preferably, the material of the slider 113 is different from that of the rack 123 or the limiting portion 114, thereby reducing wear on the rack 123 and extending the service life of the rack 123. The slider 113 may be made of a wear-resistant material. Preferably, the slider 113 is made of nylon or polyoxymethylene (POM), which has a self-lubricating effect, further reducing wear on the rack 123 and extending the service life of the device.

[0039] The support base can slow down the falling speed of the object. The conversion component converts the rotational falling force into a linear force through the gear 121 and the rack 123, and buffers it through the buffer component, thereby reducing the damage to the rod body 2 caused by falling or the damage to the rod body 2. The structure is simple, easy to use and highly reliable.

[0040] The rod body 2 is provided with an avoidance position, which is used to avoid the support base when falling, so that the rod body 2 can fall horizontally.

[0041] The support base also includes a locking assembly, such as Figure 5 and Figure 6 As shown, the locking assembly includes a stopper shaft 142 and a pedal 141. The stopper shaft 142 is used to limit the movement of the rod body 2. The stopper shaft 142 is connected to the base side wall 112. The base side wall 112 is provided with a limiting groove that cooperates with the stopper shaft 142 and is used to limit the movement direction of the stopper shaft 142. Preferably, the stopper shaft 142 is also connected to the rotating shaft 122 via a tension spring, which is used to pull the stopper shaft back after being pressed downward. Optionally, a connecting structure is provided on the base side wall 112, and the stopper shaft 142 can be connected to the connecting structure via the tension spring.

[0042] The pedal 141 is movably connected to the base bottom plate 111. Preferably, a connecting mechanism is provided on the base bottom plate 111, through which the pedal 141 is movably connected. A stopper shaft 142 is disposed below the pedal 141. Furthermore, the pedal 141 is configured to press downwardly on the stopper shaft 142. A clearance groove is also provided on the base sidewall 112, configured to clear the pedal 141 and limit its movement. The stopper shaft 142 is located below the buffer spring 132.

[0043] When it is necessary to lift, step on the pedal 141, and the stop shaft 142 moves downward under the action of the pedal 141 and the limit groove, so that the stop shaft 142 is separated from the rod body 2. At this time, lift the rod body 2. After the rod body 2 is pulled up, release the pedal 141, and the stop shaft 142 moves upward under the action of the tension spring and clamps the side of the rod body 2.

[0044] When the lever 2 needs to be lowered, the pedal 141 is stepped on, and the stop shaft 142 moves downward under the action of the pedal 141 and the limit groove, so that the stop shaft 142 is separated from the lever 2, and the lever 2 can be lowered. After the lever 2 is lowered, the pedal 141 is released, and the stop shaft 142 moves upward under the action of the tension spring, which can be locked or unlocked at the bottom of the lever 2.

[0045] The adapter also includes a warning assembly connected to the rod body 2 or the support base. The warning assembly is used to warn the user in dimly lit or poorly illuminated parking lots to prevent the device from being run over or collided with by a car, which could cause damage to the device or the car. The warning assembly includes a reflective layer, a fluorescent layer, and / or a warning light.

[0046] The charging site includes the switching device. Preferably, the charging site includes a self-powered charging site and a mechanical charging site.
