Description

A wireless charging station suitable for AGV tractor transport vehicles Technical Field

[0001] This utility model relates to the field of wireless power transmission, and in particular to a wireless charging station suitable for AGV tractor transport vehicles. Background Technology

[0002] A wireless charging station for AGV towing vehicles is an intelligent charging device that provides power to AGVs through non-contact energy transfer technology. It achieves power transfer through the principle of electromagnetic induction, eliminating the need for physical plugging and unplugging. This can significantly improve the automation level and operating efficiency of AGVs, and is especially suitable for intelligent warehousing and intelligent manufacturing scenarios that require 24-hour continuous operation. However, if the front or rear of an AGV towing vehicle is not aligned with the wireless charging station when it arrives, the efficiency of wireless charging cannot be fully utilized, which forces the charging time to be extended. This disrupts the originally efficient charging rhythm and affects the stability and efficiency of the charging process. Summary of the Invention

[0003] In order to overcome the shortcomings of the prior art where the vehicle body tilt leads to a decrease in charging efficiency, the technical problem of this utility model is to provide a wireless charging station suitable for AGV tractor transport vehicles that can correct the vehicle body.

[0004] A wireless charging station suitable for AGV tractor transport vehicles includes a wireless charging station, a mounting frame fixedly connected to the top of the wireless charging station, a guide groove formed in the middle of the mounting frame, a motor fixedly connected to the middle right side of the mounting frame, a lead screw rotatably connected to the middle of the mounting frame, the output shaft of the motor being fixedly connected to the right end of the lead screw, a slider slidably connected to the middle of the mounting frame, the slider being threadedly connected to the lead screw, the bottom of the slider being fixedly connected to the top of a hydraulic cylinder, and the telescopic rod of the hydraulic cylinder being fixedly connected to the top of a push block.

[0005] Furthermore, it also includes limiting rods. Three limiting grooves are evenly opened in the middle of the push block along the horizontal direction. The three limiting rods pass through the limiting grooves and are slidably connected to the push block. The right ends of the limiting rods are fixedly connected to the buffer plate. Springs are sleeved on the limiting rods. One end of the spring is fixedly connected to the buffer plate, and the other end of the spring is fixedly connected to the push block. The buffer plate is used to buffer the impact force when the AGV body contacts the push block.

[0006] Furthermore, it also includes ball bearings, with multiple ball bearings installed on the right side of the buffer plate.

[0007] Furthermore, it also includes a rubber pad, which is fixedly connected to the bottom of the push block.

[0008] Furthermore, it also includes a detector. The detector is installed in the middle of the left side of the wireless charging station to detect the position of the AGV towing vehicle when it approaches in real time.

[0009] Furthermore, it also includes a telescopic pad, which is slidably connected to the bottom of the mounting bracket.

[0010] Compared with the prior art, the present invention has the following advantages: 1. The hydraulic cylinder pushes the push block to move up and down, the motor drives the lead screw to rotate, the lead screw drives the slider to move left and right along the guide groove, and the hydraulic cylinder and push block also move accordingly, so as to realize the horizontal position correction of the vehicle body, so that the vehicle body and the wireless charging station reach the ideal alignment state, and ensure the efficient operation of wireless charging.

[0011] 2. By squeezing the buffer plate, the limit rod moves to the left. The spring acts as a buffer, avoiding damage to the vehicle body and charging station, extending the service life of the equipment, reducing the maintenance cost of equipment failure caused by frequent collisions and impacts, and ensuring the long-term stable operation of the entire charging system.

[0016] First, it should be noted that in different described embodiments, the same components are given the same reference numerals or the same component names. The disclosure contained throughout this specification can be applied semantically to the same components having the same reference numerals or the same component names. The location descriptions selected in the specification, such as upper, lower, lateral, etc., also refer to the directly described and illustrated figures and are semantically applied to the new location when the location changes.

[0017] Example: A wireless charging station suitable for AGV tractor transport vehicles, as shown in Figures 1-3, includes a wireless charging station 1, a mounting frame 2, a motor 3, a lead screw 4, a slider 5, a hydraulic cylinder 6, and a push block 7. The top of the wireless charging station 1 is fixedly connected to the mounting frame 2. A guide groove is provided in the middle of the mounting frame 2. The motor 3 is fixedly connected to the middle right side of the mounting frame 2. The lead screw 4 is rotatably connected to the middle of the mounting frame 2. The output shaft of the motor 3 is fixedly connected to the right end of the lead screw 4. The slider 5 is slidably connected to the middle of the mounting frame 2. The slider 5 is threadedly connected to the lead screw 4. The bottom of the slider 5 is fixedly connected to the top of the hydraulic cylinder 6. The telescopic rod of the hydraulic cylinder 6 is fixedly connected to the top of the push block 7. It also includes limiting rods 8, buffer plates 9, and springs 10. Three limiting grooves are evenly distributed horizontally in the middle of the push block 7. The three limiting rods 8 pass through the limiting grooves and are slidably connected to the push block 7. The right ends of the limiting rods 8 are fixedly connected to the buffer plates 9. Springs 10 are sleeved on the limiting rods 8, with one end of each spring fixedly connected to the buffer plates 9 and the other end fixedly connected to the push block 7. It also includes ball bearings 11, with multiple ball bearings 11 installed on the right side of the buffer plates 9. It also includes a rubber pad 12, which is fixedly connected to the bottom of the push block 7. Finally, it includes a detector 13, which is installed in the middle of the left side of the wireless charging station 1.

[0018] When using this device, when the AGV tractor needs charging and drives towards the wireless charging station 1, the control system of the wireless charging station 1 will use the detector 13 installed on the left side to detect the vehicle's position in real time as it approaches, determining whether there is any misalignment such as the vehicle being tilted. The control system will then first control the hydraulic cylinder 6 to start, causing the extension rod of the hydraulic cylinder 6 to push the push block 7 downwards. The rubber pad 12 at the bottom of the push block 7 can buffer any potential collision with the ground, thus avoiding direct rigid contact with the ground and protecting the push block 7 and the ground. Subsequently, the control system will control the motor 3 to operate, and the motor 3 will drive the lead screw 4 to rotate. The lead screw 4 will drive the slider 5 to move to the right along the guide groove on the mounting bracket 2. During this process, the slider 5 will drive the hydraulic cylinder 6 to move to the right synchronously, and the push block 7 will also move to the right along with the hydraulic cylinder 6. When the push block 7 moves to the right, it will drive the buffer plate 9 to move to the right as well. The buffer plate 9 is equipped with multiple... The ball bearing 11 will first contact the AGV body, reducing the friction between the buffer plate 9 and the body, making the subsequent pushing process smoother. As the buffer plate 9 continues to move to the right, it will gradually apply a pushing force to the AGV body. When the AGV body exerts a rightward reaction force on the buffer plate 9, the spring 10 is in a compressed state, which also plays a buffering role. The buffer plate 9 drives the limiting rod 8 to move to the left along the limiting groove to avoid excessive impact force causing damage to the body. With the continuous movement of the slider 5 and the continuous pushing of the buffer plate 9 on the body, the AGV body is corrected to a suitable charging alignment position. After the AGV body is corrected to the appropriate position, the wireless charging station 1 can conduct non-contact power transmission with the receiving device on the AGV through the principle of electromagnetic induction to charge the AGV towing vehicle, realizing efficient power transmission and ensuring that the vehicle can be successfully recharged. After charging is completed, the AGV will automatically drive away from the wireless charging station 1, the hydraulic cylinder 6 will reset and retract the push block 7, and the motor 3 will reverse to drive the slider 5 back to its position.

[0019] As shown in Figure 2, the mounting bracket 2 also includes a telescopic pad 14, which is slidably connected to the bottom of the mounting bracket 2.

[0020] The telescopic pad 14 installed on the mounting bracket 2 effectively prevents impurities from damaging the lead screw 4, ensuring the smoothness and reliability of the lead screw 4 transmission.
