Description

[0002] With the rapid development and maturation of Automated Guided Vehicle (AGV) technology, it has been gradually applied to various production and work environments such as factories, warehouses, and logistics, replacing traditional manual handling and playing a significant role in improving production efficiency. In common application scenarios, multiple, dozens, or even hundreds of AGVs often need to operate continuously 24 hours a day without human management or maintenance. However, a fully charged AGV can typically only run for a few hours. Therefore, timely and efficient management of AGV battery power is necessary to ensure the AGV's transportation efficiency.

[0003] Traditional technologies typically involve setting up charging rooms or charging piles, manual charging, or automatic charging to replenish the power of AGVs. However, when using charging rooms or charging piles, different AGVs often have different battery packs, and existing power stations often cannot charge AGVs or battery packs of various sizes.

Each first guide rail assembly includes a first slide rail and a first slider that are slidably connected.

Many specific details are set forth in the following description to provide a full understanding of this utility model. However, this utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this utility model. Therefore, this utility model is not limited to the specific embodiments disclosed below.

[0036] Please refer to Figures 1 to 4This application provides a charging guide device 100, located in a power station configured to automatically charge the battery of a mobile robot. The charging guide device 100 includes a base plate 101, a telescopic base plate 102, and a guide mechanism 110. The telescopic base plate 102 is slidably connected to the base plate 101 along a first direction X; the guide mechanism 110 is fixedly connected to the telescopic base plate 102. The guide mechanism 110 includes a first drive assembly 113 and a first guide member 111 and a second guide member 112 sequentially connected to the output end of the first drive assembly 113 along a second direction Y. The first drive assembly 113 drives the first guide member 111 and the second guide member 112 to synchronously open and close along the second direction Y. The first direction X is perpendicular to the second direction Y. In this way, the guiding mechanism 110 of the charging guiding device 100 drives the first guide member 111 and the second guide member 112 to open and close via the first driving component 113. The area formed between the first guide member 111 and the second guide member 112 can guide different mobile robots or batteries of different sizes. Simultaneously, the charging guiding device 100, through the telescopic base plate 102, allows the guiding mechanism 110 to control the distance between itself and the battery of the mobile robot according to the battery specifications. Furthermore, the opening and closing of the guide plate of the first driving component 113 and the telescopic base plate 102 form a dual-axis motion system, enabling dual adjustment of the position and attitude (lateral centering + longitudinal pushing) of the battery or other devices to be charged, adapting to complex charging scenarios and enabling charging of batteries of different specifications. Therefore, the charging guiding device 100 or power station provided in this application embodiment can adapt to batteries or mobile robots of different sizes, improving the compatibility of the power station, increasing operating efficiency, and reducing charging costs.

[0037] The power supply station also includes a power supply component 120, which is used to replenish the depleted battery of the mobile robot based on the power supply command output of the power supply station's electronic control component after the charging guide device 100 completes the positioning compensation of the mobile robot.

[0038] It should be noted that, although Figure 1 The base plate 101 is referred to as the bottom plate, but this does not mean that the base plate 101 is located vertically below during operation. The base plate 101 can be fixed to other base frames or systems by fasteners, or the base plate 101 can also be in the form of a top plate. Its orientation is not limited by the name.

[0039] In one feasible implementation, the power supply component 120 is floatingly connected to the telescopic base plate 102. In this way, the floating power supply component 120 adjusts itself based on external forces, thereby enabling temporary power supply connection and compensation for positioning errors of the mobile robot, which helps improve power supply stability and extend the service life of the power station.

[0040] In one feasible implementation, the first drive assembly 113 includes a first drive motor 1131 and a first lead screw assembly. The first lead screw assembly is connected to the output end of the first drive motor 1131 via a coupling 1133. The first lead screw assembly includes a left-handed lead screw 11321 and a right-handed lead screw 11322 connected along the second direction Y. The first guide member 111 is connected to the left-handed lead screw 11321 via a first connecting plate 1133. The second guide member 112 is connected to the right-handed lead screw 11322 via a second connecting plate 1134. Thus, by using the first lead screw assembly with reverse rotation or reverse thread, the unidirectional output end of the first drive motor 1131 can control the opening and closing of the first guide member 111 and the second guide member 112. Only one drive motor is needed to synchronously control the opening and closing actions of the two guide plates, greatly simplifying the mechanical structure and reducing the size and space occupied by the equipment. Meanwhile, the left-hand and right-hand screws 11322 have opposite thread directions, ensuring that the first and second guides achieve completely symmetrical synchronous opening and closing (such as mirror motion) when the motor rotates in one direction, keeping them always centered and avoiding action delays or position deviations caused by multi-motor control.

[0041] In one feasible implementation, the guide mechanism 110 further includes a first nut 1135 and a second nut 1136. The first nut 1135 is sleeved on the left-hand lead screw 11321. The first connecting plate 1133 is fixedly connected to the first nut 1135. The second nut 1136 is sleeved on the right-hand lead screw 11322, and the second connecting plate 1134 is fixedly connected to the second nut 1136. In this way, when the threaded engagement between the nut and the lead screw converts the rotational motion into linear motion, the load is uniformly transmitted through surface contact (rather than point contact), reducing vibration and impact, and avoiding jitter during the movement of the guide plate. The backlash of the lead screw drive can be eliminated by pre-tightening the nut (such as a double-nut opposing structure), ensuring the opening and closing positioning accuracy of the guide plate (up to ±0.01mm level based on the thread). The rigid connection between the nut and the lead screw can withstand greater axial force; the fixed design of the nut and the connecting plate can resist lateral torque and prevent the lead screw from bending and deforming due to eccentric load.

[0042] In one feasible implementation, the left-hand lead screw 11321 and the right-hand lead screw 1132 can also be connected to the first drive motor 1131, the first guide member 111, or the second guide member 112 through gear meshing to realize the transmission of kinetic energy, which will not be elaborated here.

[0043] In one feasible implementation, the guiding mechanism 110 further includes a first guiding assembly. The first guiding assembly is used to guide the opening and closing movements of the first guide member 111 and the second guide member 112 along the second direction Y. By providing the first guiding assembly, the movement of the nut and the lead screw driven by the guide plate can be further guided, avoiding bending and deformation of the lead screw due to eccentric load.

[0044] In one feasible implementation, the first guide assembly includes two first guide rail assemblies. The two first guide rail assemblies respectively guide the first connecting plate 1133 and the second connecting plate 1134. The first guide rail assembly includes a first slide rail 1141 and a first slider 1142 that are slidably connected. The first slide rail 1141 is fixedly connected to the telescopic base plate 102 along the second direction Y, and the first slider 1142 is connected to the first connecting plate 1133 or the second connecting plate 1134.

[0045] In one feasible implementation, the first guide component can also be in the form of a guide rod. For example, a through guide hole is opened in the first connecting plate 1133 and the second connecting plate 1134 along the second direction Y. The guide rod passes through the guide hole and can also guide the movement of the lead screw and the connecting member, thereby improving the reliability of the equipment.

[0046] In one feasible implementation, one end of the first guide member 111 and the second guide member 112 along the first direction X is connected to the first drive assembly 113, and the other end is used to connect to the receiving charging device. The ends of the first guide member 111 and the second guide member 112 connected to the device to be charged are chamfered. The chamfer forms a "guide slope," which automatically corrects minor positional deviations when the mobile robot is inserted, reducing the stringent requirements for initial positioning accuracy. The chamfer design also avoids hard collisions between right-angled edges and the device interface, reducing the risk of mechanical jamming due to slight misalignment and improving the smoothness of the power supply process.

[0047] In one feasible implementation, the guiding mechanism 110 further includes two connecting rods 115, which are parallel to the first guide member 111 and the second guide member 112. Optionally, at least a portion of the surface of the connecting rod 115 near the mobile robot is inclined, for example, it can be a conical surface, which facilitates the smooth insertion of the connecting rod 115 into the guide slot on the mobile robot. Since the connecting rod 115 can cooperate with the guide slot on the mobile robot, the connecting rod 115 is adjusted under the interaction force between the connecting rod 115 and the guide slot during positioning until the connecting rod 115 and the guide slot are relatively parallel or the interaction force between them is less than or equal to a set threshold. After the connecting rod 115 completes the pose adjustment (e.g., parallel to the side wall of the battery compartment of the mobile robot), the first guide member 111 and the second guide member 112 also complete the pose adjustment accordingly, and the power supply component 120 can also complete the docking with the charging port of the mobile robot to provide power or charge.

[0048] In one feasible implementation, the charging guide device 100 further includes a second drive component 131. The second drive component 131 is disposed on the base plate 101 and is used to drive the telescopic base plate 102 to move along the first direction X. The opening and closing of the guide plate of the first drive component 113 and the extension and retraction of the telescopic base plate 102 of the second drive component 131 form a dual-axis motion system, which can realize dual adjustment of the position and attitude of the battery or other devices to be charged (lateral centering + longitudinal pushing), adapting to complex charging or battery swapping scenarios.

[0049] Furthermore, the second drive assembly 131 can be an electric actuator, a linear motor, or a pneumatic actuator. Among them, the electric actuator converts rotation into linear motion through a motor and a lead screw or gear, which has a simple structure, low cost, and good self-locking performance.

[0050] In one feasible implementation, the second drive assembly 131 includes a drive section and a transmission section. The drive section includes a second drive motor. The transmission section includes a drive wheel 1311, a synchronous pulley 1312, a synchronous belt 1313, and a second lead screw 1314. The second drive motor is mounted on the base plate 101. The second lead screw 1314 is rotatably connected to the base plate 101. The drive wheel 1311 is fixed to the output shaft of the second drive motor. The synchronous pulley 1312 is fixed to the second lead screw 1314, and the synchronous belt 1313 is wound around the drive wheel 1311 and the synchronous pulley 1312. Through the meshing of the drive wheel 1311 and the synchronous pulley 1312, the rotational power of the motor is transmitted to the lead screw without slippage, resulting in high transmission efficiency and reduced energy loss. The second lead screw 1314 converts the rotational motion into the linear motion of the telescopic base plate 102, and combined with the ball screw design, it can achieve micron-level positioning accuracy, meeting the high-precision requirements of battery docking. By changing the gear ratio between the drive wheel 1311 and the synchronous pulley 1312 (e.g., 1:2 or 1:3), different telescopic speeds and thrust requirements can be adapted without replacing the motor. The flexible transmission of the synchronous belt 1313 can buffer the impact of motor start-up and shutdown, avoid mechanical vibration caused by rigid connection, and improve system stability. In addition, the drive motor is mounted on the side of the base plate 101, and the synchronous belt 1313 drives the lead screw across the space, freeing up the installation space under the telescopic base plate 102, which is convenient for integrating sensors or heat dissipation structures. The drive unit (motor) and the transmission unit (lead screw) are physically separated by the synchronous belt 1313, lowering the overall center of gravity and enhancing the device's anti-tipping ability (especially suitable for vehicle-mounted mobile charging equipment). The synchronous belt 1313 replaces the gearbox, eliminating the need for a multi-stage gear reduction mechanism and reducing weight and volume. The lead screw only needs to cover the stroke of the telescopic base plate 102, which significantly reduces material costs and space occupation compared to a linear motor, and can achieve ultra-large stroke telescopic extension.

[0051] In one feasible implementation, the second drive assembly 131 further includes a second guide assembly 132. The second guide assembly 132 includes at least one second guide rail assembly. The second guide rail assembly includes a second slide rail 1321 and a second slider 1322 that are slidably connected. The second slide rail 1321 is fixedly connected to the base plate 101 along the first direction X. The second slider 1322 is connected to the telescopic base plate 102. The rigid guidance of the slide rail and the slider constrains the telescopic base plate 102 to move in a pure linear motion along the first direction X, eliminating lateral offset caused by radial backlash of the lead screw or external loads (such as lateral force when a battery is inserted at an angle). The slider has built-in rolling elements (balls or rollers) to disperse motion friction, reduce the vibration amplitude during high-speed telescopic movement, and ensure that the positioning accuracy is stable within ±0.05mm. The guide rail bears all lateral loads, unloads the radial force of the lead screw, avoids deformation or premature wear of the lead screw due to bending moment, and extends the service life of the transmission system. When multiple sets of slide rails are arranged in parallel, the center of gravity offset load of the telescopic base plate 102 can be evenly distributed, preventing single-point stress concentration from causing guide rail or slider failure. Furthermore, the high-rigidity structure of the slide rail (such as a heavy-duty guide rail with a rectangular cross-section) can withstand axial pressure of several tons.

[0052] Furthermore, the second lead screw 1314 is also connected to the telescopic base plate 102 via a flexible connection assembly 133. The flexible connection assembly 133 may include a nut connector sleeved on the second lead screw 1314, and two spring shafts passing through the nut connector, the two spring shafts being symmetrical about the central axis of the second lead screw 1314. The two ends of the two spring shafts along the first direction X are respectively fixedly connected to spring fixing plates fixed to the two ends of the telescopic base plate 102 along the first direction X. Springs are respectively sleeved on the two spring shafts. This softens the jerking sensation when the second drive assembly 131 drives the lead screw to rotate, thereby improving the smoothness of the telescopic movement.

[0053] Accordingly, this application also provides a power station, including: a charging guide device 100 as described above; a power supply mechanism; and an electronic control component, electrically connected to the charging guide device 100 and the power supply mechanism, configured to control the charging guide device 100 and the power supply mechanism to adjust their posture based on received charging information to charge batteries of mobile robots of different specifications. In this way, the opening and closing of the guide plate of the first drive component 113 of the charging guide device 100 and the extension and retraction of the telescopic base plate 102 form a dual-axis motion system, which can realize dual adjustment of the position and posture (lateral centering + longitudinal pushing) of the battery or other devices to be charged, adapting to complex charging scenarios and enabling charging of batteries of different specifications. Therefore, the charging guide device 100 or power station provided in this application can adapt to batteries or mobile robots of different sizes, improving the compatibility of the power station, increasing operating efficiency, and reducing charging costs.

[0054] In one feasible implementation, the power supply component 120 is floatingly connected to the telescopic base plate 102. In this way, the floating power supply component 120 adjusts itself based on external forces, thereby enabling temporary power supply connection and compensation for positioning errors of the mobile robot, which helps improve power supply stability and extend the service life of the power station.

[0055] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0056] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
