[0002] Driverless vehicles have already appeared in people's field of vision. Currently, driverless vehicles have shown a development trend in the fields of express delivery, sanitation, security patrols, and food delivery. In the future, driverless technology will definitely become a major trend.

[0003] Unmanned vehicles are fully automatic with basically no human intervention, but the charging guns of traditional charging piles usually require manual operation. The charging gun must be pulled out from the charging pile with force and then aimed at the charging end of the vehicle for charging. During this process, the life of the charging equipment is often affected due to improper operation or plugging and unplugging too hard. The charging cable connected to the charging gun is in friction with the ground for a long time, which can easily wear out the outer protective layer of the cable and cause leakage, posing a safety hazard. Some automatic charging piles also use six-axis or multi-degree-of-freedom robotic arms to connect the charging gun to the vehicle's power receiving end for charging, but the structure is complex and the cost is high.

DETAILED DESCRIPTION

[0028] In order to make the purpose, technical solutions and advantages of the embodiments of the utility model clearer, the implementation methods of the utility model are described in detail below in conjunction with the accompanying drawings, but the embodiments described in the utility model are only part of the embodiments of the utility model, rather than all the embodiments.

[0029] like Figure 1-Figure 9As shown, this embodiment provides a two-axis adaptive charging device, including a lifting and lateral movement mechanism, a pile-end plug assembly 100 arranged on the lifting and lateral movement mechanism, and a vehicle-end power receiving socket assembly 200 arranged at the rear end of the unmanned vehicle, the vehicle-end power receiving socket assembly 200 includes a vehicle-end power receiving socket 210, and an inductor 211 is provided on the outward side of the vehicle-end power receiving socket 210.

[0030] Specifically, Figure 2-Figure 4 As shown, the pile-end plug assembly 100 includes a pile-end plug 110, a plug mounting seat 120, and a camera module 130. The front end of the pile-end plug 110 is used to connect to the vehicle-end power receiving socket 200. The plug mounting seat 120 is arranged at the rear end of the pile-end plug 110 and is connected to the lifting and lateral movement mechanism. The camera module 130 is arranged on the plug mounting seat 120, and is used to obtain image information of the position of the vehicle power receiving socket 200, and transmit the obtained image information to the upper camera position, so that the upper camera position outputs a control signal to the lifting and lateral movement mechanism according to the image information to control the movement of the plug mounting seat 120, so as to adjust the pile-end plug 110, so that the pile-end plug 110 is aligned with the vehicle-end power receiving socket 200, so that the pile-end plug 110 is connected to the vehicle-end power receiving socket 210. After the connection is in place, the sensor 211 sends an in-place instruction to the upper camera position, thereby realizing automatic charging.

[0031] When in use, the unmanned vehicle backs up to the front of the charging device, and uses the camera module 130 to obtain the position of the vehicle-end power socket 210, and transmits the obtained position image information to the upper position, and the upper position controls the movement of the lifting and lateral movement mechanism according to the image information, so that the lifting and lateral movement mechanism drives the plug mounting seat 120 to move, so that the pile end plug 110 is aligned with the vehicle-end power socket 210, and then the unmanned vehicle slowly continues to back up in the direction of the pile end plug 110, so that the vehicle-end power socket 210 is inserted into the pile end plug 110, and after the connection is in place, the sensor 211 sends a position instruction to the upper position, so that the upper position turns on the power supply, thereby realizing automatic charging. The vehicle power socket 210 is set at the rear end of the driving direction of the unmanned vehicle in order to have better waterproof performance and beautiful appearance when running on rainy days.

[0032] Specifically, the lifting and lateral movement mechanism in this solution includes a coreXY structure, which includes a group of X-axes 11 that are parallel and spaced from top to bottom, and a group of guide holes 121 are spaced on the plug mounting seat 120, which are parallel and spaced, and a sleeve is installed in the guide hole 121, so that the X-axis 11 passes through the sleeve in the guide hole 121. After a period of use, if the sleeve and the X-axis 11 are worn, the sleeve can be replaced without replacing the plug mounting seat 120, saving costs. Therefore, the plug mounting seat 120 can slide along the axis of the X-axis 11, so that the X-axis 11 is a parallel movement guide for the plug mounting seat 120.

[0033] Specifically, Figure 3-Figure 6 As shown, a guide shaft 140 is provided on one side of the plug mounting seat 120 facing the pile end plug 110, and one end of the guide shaft 140 away from the plug mounting seat 120 is connected to the rear end of the pile end plug 110; a group of opening grooves 141 are symmetrically provided on the outer side of the guide shaft 140, and connecting holes 122 are respectively provided on both sides of the plug mounting seat 120, and the axis of the connecting hole 122 is perpendicular to the midline of the length direction of the opening groove 141, and a positioning pin 123 is provided in the connecting hole 122, and one end of the positioning pin 123 passes through the connecting hole 122. The connecting hole 122 is slidably matched with the opening groove 141. A plurality of first rectangular springs 150 are provided between the pile end plug 110 and the plug mounting seat 120, and are respectively located on both sides of the guide shaft 140. When the pile end plug 110 is subjected to an external force, the pile end plug 110 pushes the guide shaft 140 to move toward the plug mounting seat 120, so that the opening groove 141 slides along one end of the positioning pin 123 and the first rectangular spring 150 is compressed, thereby unloading the external force and avoiding damage to the pile end plug 110.

[0034] Specifically, Figure 2-Figure 5 As shown, two groups of Y axes 12 are arranged at intervals at the left and right ends of a group of X axes 11, and the two groups of Y axes 12 are arranged vertically. Synchronous wheels 13 are respectively arranged at the upper and lower ends of the two groups of Y axes 12, and the synchronous wheels 13 are connected by synchronous belts 14. A servo motor is coaxially arranged on one side of the synchronous wheels 13 at the upper ends of the two groups of Y axes 12. A moving seat is respectively arranged at both ends of a group of X axes 11, and the moving seat is slidably connected with the Y axis 12. Blind grooves 124 are respectively arranged on both sides of the upper end of the plug mounting seat 120, and the blind grooves 124 are spaced and located at the upper side of the guide hole 121 at the upper end of the plug mounting seat 120. The blind grooves 124 are recessed along the two sides of the plug mounting seat 120. The two ends of the synchronous belt 14 are respectively inserted into the corresponding blind grooves 124, and the two ends of the synchronous belt 14 are fixed in the blind grooves 124, so that the movement of the synchronous belt 14 drives the movement of the plug mounting seat 120.

[0035] When in use, the camera module 130 obtains image information of the position of the vehicle-end power socket 200, and transmits the obtained image information to the main console, so that the main console sends a control signal to the motor of the coreXY structure according to the image information to control the motor to drive the corresponding synchronous wheel to rotate, so that the synchronous belt drives the plug mounting seat 120 to drive the pile-end plug 110 to move, thereby realizing the position adjustment of the pile-end plug 110.

[0036] Specifically, Figure 3 , Figure 5As shown, pressure blocks 125 are respectively provided on the two side surfaces of the upper end of the plug mounting seat 120, and the position of the pressure block 125 corresponds to the position of the blind groove 124, so that the pressure block 125 presses the connection between the synchronous belt and the notch of the blind groove 124, and screws 126 are used to screw into the side surface of the plug mounting seat 120 from the outward side of the pressure block 125, so that the plug mounting seat 120 is fixedly connected to the synchronous belt 14.

[0037] Specifically, Figure 2 , Figure 5 As shown, a strip-shaped through groove 127 is provided at the lower end of the plug mounting seat 120, which is located at the lower side of the guide hole 121 below the plug mounting seat 120, and the middle section of the synchronous belt 14 is passed through the strip-shaped through groove 127. The middle section claimed here does not refer to the end in the middle of the synchronous belt 14, but refers to the middle part relative to the two ends of the synchronous belt 14, so as to avoid the plug mounting seat 120 interfering with the movement of the synchronous belt 14.

[0038] Specifically, Figure 5 , Figure 7-Figure 9 As shown, a group of pile end guide pins 160 are provided at the outer end of the pile end plug 110, and the group of pile end guide pins 160 are arranged in parallel and at intervals, and the length of the group of pile end guide pins 160 is greater than the length of the pile end plug 110.

[0039] A vehicle-end mounting seat 220 is provided at one end of the vehicle-end power receiving socket 210, and a group of vehicle-end guide cylinders 230 are provided on the outward side of the vehicle-end mounting seat 220, and the group of vehicle-end guide cylinders 230 are arranged in parallel and at intervals, and the length of the vehicle-end guide cylinders 230 is greater than the length of the vehicle-end power receiving socket 210, so that the center distance of a group of vehicle-end guide cylinders 230 is consistent with the center distance of a group of pile-end guide pins 160. During charging, the pile-end guide pins 160 first cooperate with the vehicle-end guide cylinders 230, and as the unmanned vehicle moves toward the pile-end plug 110, the pile-end guide pins 160 cooperate with the vehicle-end guide cylinders 230 to guide the pile-end plug 110 and the vehicle-end socket 210, so that the vehicle-end socket 210 is accurately connected to the pile-end plug 110.

[0040] Specifically, a universal joint 240 is provided on one side of the vehicle-end mounting seat 220 facing the unmanned vehicle, so that the vehicle-end power receiving end 210 can better adapt to the position of the pile-end plug 110. A floating mounting plate 250 is provided on one end of the universal joint 240 facing the unmanned vehicle. A plurality of second rectangular springs 260 are provided between the vehicle-end mounting seat 220 and the opposite side of the floating mounting plate 250, so that the second rectangular springs 260 are distributed on the outer periphery of the universal joint 240 to buffer the impact force when the pile-end guide pin 160 contacts the vehicle-end guide cylinder 230.

[0041] The above is only a preferred embodiment of the utility model, and does not mean that it is the only one or limit the utility model. Those skilled in the art should understand that various changes or equivalent replacements made to the utility model without departing from the scope of the utility model are within the scope of protection of the utility model.
