Description

Technical Field

[0001] This application relates to the field of AGV vehicles, and in particular to an AGV vehicle and a charging station. Background Art

[0002] Nuclear waste generally refers to the radioactive waste that is no longer needed in the production and processing of nuclear fuel and used in nuclear reactors. Usually, nuclear waste can be divided into solids, liquids, and gases. For the treatment of nuclear waste, nuclear waste is usually collected in a tank-like container, and then these containers are centrally stored to achieve the treatment of nuclear waste.

[0003] Currently, for the centralized transportation of containers, usually a manipulator grabs the container onto the AGV vehicle, and then the AGV vehicle centrally transports the container to the waste storage point, thus avoiding the harm caused by the radiation generated by nuclear waste to the human body. After operating for a period of time, the AGV vehicle needs to drive to the charging station for charging and perform data exchange during the charging process.

[0004] When the AGV vehicle is charging, it is necessary to align the charging interface on the AGV vehicle with the charging interface on the charging station and insert them to achieve the work of charging and data exchange. However, due to the deviation in positioning accuracy of the AGV vehicle, there will be a deviation between the charging interface on the AGV vehicle and the charging interface on the charging station, which causes the AGV vehicle to continuously adjust its position to complete the charging action, resulting in a low charging efficiency of the AGV vehicle. Summary of the Invention

[0005] In order to improve the charging efficiency of the AGV vehicle, this application provides an AGV vehicle and a charging station.

[0006] In the first aspect, this application provides an AGV vehicle, adopting the following technical solution:

[0007] An AGV vehicle includes a frame, on which a traveling device and an energy storage device are installed. The energy storage device is used to supply power to the traveling device, and the traveling device is used to drive the frame to move. A charging device is also installed on the frame. The charging device includes a male connector and a buffer mechanism. The male connector is connected to the energy storage device and is used to connect the energy storage device to an external power source. The buffer mechanism is installed on the frame and is connected to the male connector.

[0008] By adopting the above technical solution, the energy storage device supplies power to the traveling device, so that the traveling device drives the vehicle frame to move, thereby realizing the movement of the transport container. When the AGV cart needs to be charged, the traveling device drives the vehicle frame to move to an external power source, connects the male connector to the external power source, thereby charging the energy storage device, and during the connection process between the male connector and the external power source, the male connector is buffered by the buffer mechanism, enabling the male connector to offset within a certain range, so as to better connect with the external power source, facilitating the reduction of the situation where the AGV cart needs to repeatedly adjust its position, and thus improving the charging efficiency of the AGV cart.

[0009] In a specific feasible implementation, a first magnetic block is installed on the male connector, and the first magnetic block is used to adsorb on the power supply component of the external power source.

[0010] By adopting the above technical solution, when the vehicle frame moves to make the male connector approach the external power source, the male connector adsorbs on the power supply component of the external power source through the first magnetic block, thus facilitating the charging of the energy storage device.

[0011] In a specific feasible implementation, the buffer mechanism includes a buffer spring and a buffer rod. A buffer ring is installed at the end of the vehicle frame. One end of the buffer rod is connected to the vehicle frame, and the other end passes through the buffer ring and extends away from the vehicle frame. The male connector is installed at the end of the buffer rod away from the vehicle frame. A limiting rod is installed on the side wall of the buffer rod at the position of the buffer ring, and the axis of the limiting rod is perpendicular to the axis of the buffer rod. The buffer spring is installed on the positioning rod, and one end of the buffer spring abuts against the side wall of the buffer rod, and the other end abuts against the inner side wall of the buffer ring.

[0012] By adopting the above technical solution, when the male connector is connected to the external power source through the first magnetic block, the male connector drives the buffer rod to move, causing the buffer rod to drive the buffer spring to act, thereby buffering the buffer rod, so that even if the male connector on the buffer rod is not completely aligned with the power supply component on the external power source, the male connector can still complete the adsorption action under the action of the buffer mechanism, thus facilitating the charging of the energy storage device.

[0013] In a specific feasible implementation, the traveling device includes traveling wheels and a power assembly. The power assembly is installed on the vehicle frame, the traveling wheels are installed on the bottom wall of the vehicle frame, and the power assembly is connected to the traveling wheels. The power assembly is also connected to the energy storage device.

[0014] By adopting the above technical solution, the energy storage device supplies power to the power assembly, enabling the power assembly to drive the traveling wheels to rotate, thereby driving the vehicle frame to move, thus facilitating the realization of the action of transporting the container.

[0015] In a specific feasible embodiment, the energy storage device includes a power battery, the power battery is installed on the vehicle frame, and both the male connector and the power assembly are connected to the power battery.

[0016] By adopting the above technical solution, electric energy is provided to the power assembly by the power battery, so as to facilitate the power assembly to drive the running device to work. The power battery is connected to an external power source through the male connector, so as to facilitate charging the power battery.

[0017] In a second aspect, the present application provides a charging station for an AGV cart, adopting the following technical solution:

[0018] A charging station for an AGV cart includes a charging base, on which a female connector, a locking mechanism and a delay mechanism are installed. The female connector is used to connect with the male connector. The locking mechanism is used to lock the male connector on the female connector, and the locking mechanism is also connected to the vehicle frame. The delay mechanism is connected to the locking mechanism.

[0019] By adopting the above technical solution, when the AGV cart needs to be charged, the male connector is connected to the female connector to realize charging of the AGV cart, and the male connector is locked on the female connector through the locking mechanism, so as to facilitate maintaining the stability of charging. And when locking the male connector, the locking and unlocking actions of the locking mechanism are delayed by the delay mechanism, so that the male connector can be first docked with the female connector and then locked by the locking mechanism, so as to facilitate realizing the accuracy of the docking between the male connector and the female connector.

[0020] In a specific feasible embodiment, the locking mechanism includes a locking hook, a locking spring, a pressing plate and a locking ring. A locking rod is installed on the charging base, the female connector is installed on the locking rod, a locking sleeve is installed on the locking rod, the locking hook is installed on the locking sleeve, and one end of the locking hook extends out of the locking sleeve. A reset member is installed in the locking sleeve and is connected to the locking hook. A positioning ring is installed on the male connector, and the locking hook is used to engage with the positioning ring. The locking ring is installed on the locking rod and is located inside the locking sleeve, and the locking ring is connected to the locking hook. The pressing plate is installed on the bottom wall of the charging base and is located below the female connector. The pressing plate is used to abut against the bottom wall of the vehicle frame. The pressing plate and the locking ring are connected by a push rod. The locking spring is installed on the locking rod, one end of the locking spring is connected to the locking ring, and the other end is connected to the charging base.

[0021] By adopting the above technical solution, when the AGV cart drives the male connector to move to dock with the female connector, the male connector pushes the female connector to move towards the charging base, causing the female connector to drive the locking rod to move, and the vehicle frame drives the pressing plate to rotate downward, so that the pressing plate drives the locking ring to slide along the locking rod and compress the locking spring through the push rod, causing the locking ring to drive the locking hook to rotate, so that the locking hook is clamped with the positioning ring, thereby completing the positioning of the male connector.

[0022] In a specific feasible implementation, the reset member includes a locking elastic piece, one end of the locking elastic piece is installed on the inner wall of the locking sleeve, and the other end is connected to one end of the locking hook located inside the locking sleeve.

[0023] By adopting the above technical solution, when the charging is completed, the male connector drives the female connector to move away from the charging base through the locking hook, so that the locking ring moves away from the charging base under the action of the locking spring, causing the locking ring to slide along the side wall of one end of the locking hook located inside the locking sleeve, and causing one end of the locking hook located inside the locking sleeve to rotate towards the locking rod under the action of the locking elastic piece, so that the locking hook releases the positioning ring, thereby unlocking the male connector.

[0024] In a specific feasible implementation, the delay mechanism includes a delay spring and a limit plate. The limit plate is installed on the side wall of one end of the locking rod located inside the charging base. The delay spring is installed on the locking rod and is located inside the charging base. One end of the delay spring is connected to the side wall of the limit plate, and the other end is connected to the inner wall of the charging base.

[0025] By adopting the above technical solution, when the male connector drives the female connector to move towards the charging base, the female connector drives the locking rod to move towards the charging base, causing the locking rod to drive the limit plate to pull the delay spring, so as to facilitate buffering of the female connector and enable the locking hook to lock the male connector during the buffering process of the female connector, so as to facilitate the action of delayed locking. When the charging is completed, the male connector pulls the female connector and the locking rod through the locking hook, so that the locking rod compresses the delay spring through the limit plate, and during the movement of the locking rod, the locking hook gradually releases the positioning ring on the male connector, causing the locking hook to unlock the male connector, so as to facilitate the separation of the male connector and the female connector.

[0026] In a specific feasible implementation, a second magnetic block is installed at the end of the female connector, and the second magnetic block attracts the first magnetic block.

[0027] By adopting the above technical solution, the male connector is attracted to the second magnetic block on the female connector through the first magnetic block, so as to facilitate the stable connection between the male connector and the female connector.

[0028] In summary, the present application includes at least one of the following beneficial effects:

[0029] 1. By providing a buffer mechanism in this application, it is convenient to allow a certain degree of deviation when the male connector docks with an external power supply through the buffer mechanism, thereby facilitating the reduction of the situation where the AGV cart continuously adjusts its position, and thus improving the charging efficiency of the AGV cart.

[0030] 2. By providing a locking mechanism in this application, it is convenient to lock the male connector on the charging seat when the AGV cart is charging through the locking mechanism, thereby facilitating the maintenance of charging stability.

[0031] 3. By providing a delay mechanism in this application, it is convenient to achieve delayed locking and delayed unlocking of the male connector through the delay mechanism, so as to lock the male connector after it is completely connected to the charging seat, and unlock the male connector first and then separate the male connector from the charging seat after charging is completed, thereby facilitating the reduction of equipment damage and extending the service life of the charging seat and the AGV cart.

[0045] An embodiment of the present application discloses an AGV cart. Refer to Figure 1 and Figure 2 , which includes a frame 1, a traveling device 2, an energy storage device 3, and a charging device 4 are installed on the frame 1. The traveling device 2 drives the frame 1 to travel. The energy storage device 3 is connected to the traveling device 2, and the charging device 4 is connected to the energy storage device 3.

[0046] Refer to Figure 2 , the traveling device 2 includes traveling wheels 21, a power assembly 22, and a control module (not shown in the figure). The traveling wheels 21 are installed at the lower end of the frame 1. The power assembly 22 and the control module are installed inside the frame 1. The power assembly 22 is connected to the traveling wheels 21, the control module is connected to the power assembly 22, and both the power assembly 22 and the control module are connected to the charging device 4. The control module and the power assembly 22 are both prior arts in the field and will not be elaborated here.

[0047] Refer to Figure 2 , the energy storage device 3 includes a power battery 31. The power battery 31 is installed inside the frame 1, and both the power assembly 22 and the control module are connected to the power battery 31.

[0048] Refer to Figure 3 and Figure 4, the charging device 4 includes a male connector 41 and a buffer mechanism 42. The buffer mechanism 42 includes a buffer rod 421 and a buffer spring 422. A buffer ring 423 is fixedly installed on the side wall of the end of the vehicle frame 1. One end of the buffer rod 421 is connected to the side wall of the end of the vehicle frame 1 through a universal joint, and the other end extends away from the vehicle frame 1 and passes through the buffer ring 423. Four limiting rods 424 are fixedly installed on the side wall of the buffer rod 421 at the position of the buffer ring 423. The four limiting rods 424 are arranged along the circumferential direction of the buffer rod 421, and the axis of the limiting rod 424 is perpendicular to the axis of the buffer rod 421. Four positioning rods are fixedly installed on the side wall of the inner ring of the buffer ring 423. The four positioning rods correspond to the four limiting rods 424 one by one. One end of the buffer spring 422 is sleeved on the limiting rod 424 and fixedly connected to the side wall of the buffer rod 421, and the other end of the buffer spring 422 is sleeved on the positioning rod and fixedly connected to the side wall of the inner ring of the buffer ring 423.

[0049] Referring to Figure 3 and Figure 4 , a ball head 425 is provided at the end of the buffer rod 421 away from the vehicle frame 1. The male connector 41 is ball-jointed to the end of the buffer rod 421 away from the vehicle frame 1 through the ball head 425, and the male connector 41 is connected to the power battery 31 through a charging wire 412. The male connector 41 is also connected to the control module through a data transmission line. A first magnet 411 is fixedly installed on the side wall of the end of the male connector 41 away from the buffer rod 421. The male connector 41 is used to connect to a charging station, and the first magnet 411 is used to adsorb the male connector 41 to the components on the charging station.

[0050] The working principle of the embodiment of the present application is as follows: When the AGV cart transports a certain amount of containers and needs to be charged, the driving wheel 21 is driven to rotate by the power assembly 22, so as to drive the vehicle frame 1 to move to the charging station, and the male connector 41 on the vehicle frame 1 is moved to be close to the charging interface on the charging station. The first magnet 411 on the male connector 41 adsorbs to the components on the charging station, so as to guide the male connector 41 to dock with the charging interface on the charging station. At this time, even if there is a deviation between the male connector 41 and the charging interface on the charging station, the male connector 41 can deflect under the drive of the first magnet 411, so as to dock with the charging interface on the charging station. During the deflection of the male connector 41, the male connector 41 drives the buffer rod 421 to deflect, so that the buffer rod 421 drives the buffer spring 422 to deform, so as to facilitate the buffer spring 422 to push the buffer rod 421 to reset after charging is completed, so as to drive the male connector 41 to reset.

[0051] The embodiment of the present application also discloses a charging station for an AGV cart. Referring to Figure 5 and Figure 6 , it includes a charging base 5. A female connector 6, a locking mechanism 7 and a delay mechanism 8 are installed on the charging base 5. Referring to Figure 3And Figure 6 , the female connector 6 is used to connect with the male connector 41, the locking mechanism 7 is used to lock the male connector 41, and the delay mechanism 8 is used to delay the action of the locking mechanism 7.

[0052] Referring to Figure 6 and Figure 7 , the locking mechanism 7 includes a locking hook 71, a locking spring 72, a pressing plate 73 and a locking ring 74. A locking rod 75 is slidably installed on the side wall of the charging base 5 in the horizontal direction. One end of the locking rod 75 extends into the charging base 5, and the other end extends away from the charging base 5, and the end of the locking rod 75 away from the charging base 5 is open. The female connector 6 is fixedly installed in the locking rod 75 along the axis of the locking rod 75 through a guide rod 62, and the female connector 6 is located at the open end of the locking rod 75. A second magnetic block 61 is fixedly installed at the end of the female connector 6. Referring to Figure 4 and Figure 7 , the second magnetic block 61 is used to attract the first magnetic block 411 on the male connector 41. Referring to Figure 6 , a power supply cable is fixedly installed in the guide rod 62. One end of the power supply cable is connected to the female connector 6, and the other end passes through the end of the locking rod 75 and extends into the charging base 5. A signal output module is fixedly installed in the charging base 5, and the signal output module is connected to the power supply cable. The signal output module is a prior art in this field and will not be elaborated here.

[0053] Referring to Figure 6 and Figure 7 , a locking sleeve 76 is fixedly installed at the end of the locking rod 75 outside the charging base 5. The locking sleeve 76 is arranged along the axis of the locking rod 75, and there is a gap between the inner side wall of the locking sleeve 76 and the side wall of the locking rod 75. The locking hook 71 is rotatably installed at the end of the locking sleeve 76 away from the charging base 5, and the rotation axis of the locking hook 71 is in the horizontal direction and perpendicular to the axis of the locking rod 75. One end of the locking hook 71 extends into the locking sleeve 76 between the locking rod 75 and the inner wall of the locking sleeve 76, and the other end extends away from the locking sleeve 76. Referring to Figure 4 and Figure 6 , a positioning ring 413 is fixedly installed on the peripheral side wall of the male plug, and the end of the locking hook 71 away from the locking sleeve 76 is clamped with the positioning ring 413. Referring to Figure 6 and Figure 7 , a reset member is further installed in the locking sleeve 76. The reset member includes a locking elastic piece 77. One end of the locking elastic piece 77 is fixedly installed on the inner side wall of the locking sleeve 76, and the other end abuts against the wall of the end of the locking hook 71 located inside the locking sleeve 76 and away from the side of the locking rod 75.

[0054] Referring to Figure 6 and Figure 7, the locking ring 74 is slidably mounted on the locking rod 75 along the axial direction of the locking rod 75, and the locking ring 74 is located inside the locking sleeve 76. A convex ring 741 is fixedly mounted on the side wall of one end of the locking ring 74 close to the locking hook 71. The convex ring 741 is used to abut against the side wall of the locking hook 71 on the side away from the locking spring piece 77 inside the locking sleeve 76. The locking spring 72 is mounted on the locking rod 75, and one end of the locking spring 72 abuts against one end of the locking ring 74 away from the convex ring 741, and the other end abuts against the inner wall of one end of the locking sleeve 76 close to the charging base 5.

[0055] Refer to Figure 6 and Figure 7 , a sliding rod 742 is fixedly mounted on the circumferential side wall of the locking ring 74 in the horizontal direction. The sliding rod 742 extends away from the locking ring 74 and passes through the side wall of the locking sleeve 76. A sliding groove 761 for the sliding rod 742 to slide is formed on the circumferential side wall of the locking sleeve 76 along the axial direction of the locking sleeve 76. A push rod 78 is mounted on the charging base 5. One end of the push rod 78 is rotatably connected to the bottom wall of the charging base 5, and the other end extends upward to the locking rod 75. A U-shaped ring 781 is fixedly mounted on the upper end of the push rod 78. The U-shaped ring 781 extends upward. The locking sleeve 76 is located inside the U-shaped ring 781. A deflection groove 782 for the sliding rod 742 to slide is formed on the side wall of the U-shaped ring 781. One end of the pressing plate 73 is rotatably mounted at the end of the bottom wall of the charging base 5, and the other end extends obliquely upward to the side wall of the push rod 78. A waist-shaped groove 783 is formed on the side wall of the push rod 78. One end of the pressing plate 73 close to the push rod 78 is slidably connected to the push rod 78 through the waist-shaped groove 783.

[0056] Refer to Figure 6 and Figure 7 , the delay mechanism 8 includes a delay spring 81 and a limit plate 82. The limit plate 82 is fixedly mounted at the end of one end of the locking rod 75 located inside the charging base 5. The delay spring 81 is mounted on the part of the unlocking rod located inside the charging base 5. One end of the delay spring 81 is fixedly connected to the inner wall of the charging base 5, and the other end is fixedly connected to the side wall of the limit plate 82. The elastic force of the delay spring 81 is greater than the elastic force of the locking spring 72.

[0057] Refer to Figure 8 and Figure 9 , when the AGV cart needs to be charged, the AGV cart travels to the charging base 5, so that the male connector 41 on the vehicle frame 1 moves to the female connector 6. And as the AGV cart continues to move in the direction of the charging base 5, the distance between the male connector 41 and the female connector 6 is gradually shortened, so that the male connector 41 is inserted into the female connector 6. Refer to Figure 10 , so that the first magnetic block 411 and the second magnetic block 61 attract each other, and the side wall of the positioning ring 413 abuts against the open end of the locking rod 75. At the same time, refer to Figure 9 and Figure 10, the bottom wall of the end of the frame 1 of the AGV cart just touches the top wall of the pressure plate 73. Subsequently, as the AGV cart continues to move in the direction of the charging base 5, the male connector 41 pushes the female connector 6 to move in the direction of the charging base 5, thereby driving the locking rod 75 to move into the charging base 5 and stretching the delay spring 81. At the same time, the bottom wall of the AGV cart drives the pressure plate 73 to rotate downward, so that the pressure plate 73 drives the push rod 78 to rotate in the direction of the charging base 5, so that the U-shaped ring 781 on the push rod 78 drives the locking ring 74 to move in the direction of the charging base 5 through the slide rod 742, so that the locking ring 74 compresses the locking spring 72, and the moving speed of the locking ring 74 is greater than that of the locking rod 75, so that the locking ring 74 drives the convex ring 741 to abut against the bottom wall of the locking hook 71 and slide along the bottom wall of the locking hook 71, thereby compressing the locking spring piece 77, and the end of the locking hook 71 close to the male connector 41 gradually rotates in the direction of the male connector 41. When the end of the locking sleeve 76 abuts against the side wall of the charging base 5, the locking ring 74 drives the locking hook 71 to rotate through the convex ring 741, and the locking hook 71 is clamped with the positioning ring 413 on the male connector 41, thereby realizing the positioning of the male connector 41.

[0058] Refer to Figure 9 and Figure 10, after the charging is completed, the AGV cart moves away from the charging seat 5, so that the male connector 41 drives the locking hook 71 to move away from the charging seat 5 through the positioning ring 413, causing the locking hook 71 to drive the locking sleeve 76 to move towards the charging seat 5, thereby driving the locking rod 75 to move away from the charging seat 5. At the same time, the locking rod 75 drives the locking ring 74 to move away from the charging seat 5 through the locking spring 72, causing the locking ring 74 to drive the U-shaped rod to move away from the charging seat 5, thereby driving the push rod 78 to rotate away from the charging seat 5, and then driving the pressing plate 73 to rotate away from the charging seat 5 along with the AGV cart. And relative sliding occurs between the locking ring 74 and the locking rod 75, causing the locking ring 74 to drive the convex ring 741 to slide along the bottom wall of the locking hook 71 towards the male connector 41, so that one end of the locking hook 71 close to the convex ring 741 rotates away from the locking ring 74 under the action of the locking elastic piece 77, thus making the end of the locking hook 71 close to the male connector 41 gradually separate from the positioning ring 413 on the male connector 41. When the AGV cart separates from the pressing plate 73, the locking hook 71 separates from the positioning ring 413. As the AGV cart continues to move, the male connector 41 continues to pull the female connector 6 to move a short distance by magnetic force, thereby pulling the locking rod 75 to move a short distance and continue to compress the delay spring 81 until the male connector 41 separates from the female connector 6, thus reducing the situation of pulling the charging seat 5 due to the incomplete separation of the locking hook 71 and the positioning ring 413, reducing the damage to the connection part between the female connector 6 and the charging seat 5 and the connection part between the male connector 41 and the AGV cart, and thus extending the service life of the AGV cart and the charging seat 5.

[0059] The working principle of the embodiment of the present application is as follows: When the AGV cart needs to be charged, the AGV cart travels to the charging seat 5, aligns the male connector 41 with the female connector 6 on the charging seat 5, and the AGV cart gradually approaches the charging seat 5, so that the male connector 41 is inserted into the female connector 6, and the first magnetic block 411 attracts the second magnetic block 61. After the AGV cart moves into place, the side wall of the locking sleeve 76 abuts against the side wall of the charging seat 5, and the bottom wall of the AGV cart drives the pressing plate 73 to rotate, causing the pressing plate 73 to drive the push rod 78 to rotate downward, so that the U-shaped rod drives the locking ring 74 to move towards the charging seat 5 and relative sliding occurs between the locking ring 74 and the locking rod 75, causing the locking ring 74 to drive the locking hook 71 to rotate, so that the locking hook 71 is clamped with the positioning ring 413 on the male connector 41, making the connection between the male connector 41 and the female connector 6 more stable.

[0060] When charging is completed, the AGV moves away from the charging seat 5, thereby driving the locking sleeve 76 away from the charging seat 5 through the locking hook 71. The male connector 41 drives the female connector 6 away from the charging seat 5 through magnetic force, causing the locking rod 75 to move away from the charging seat 5 along with the AGV and compress the delay spring 81. The locking ring 74, under the action of the locking spring 72, slides along the locking rod 75 away from the charging seat 5 and drives the U-shaped rod to move, so that the U-shaped rod drives the pressure plate 73 to rotate upward through the push rod 78, and causes the locking ring 74 and the locking rod 75 to slide relative to each other. When the bottom wall of the AGV separates from the pressure plate 73, the protruding ring 741 on the locking ring 74 releases the interference with the locking hook 71, thereby separating the locking hook 71 from the positioning ring 413 on the male connector 41, thereby releasing the lock on the male connector 41. Moreover, as the AGV continues to move away from the charging base 5, the male connector 41 continues to pull the female connector 6 through magnetic force, thereby driving the locking rod 75 to continue to move a short distance away from the charging base 5, so that the delay spring 81 continues to be compressed until the male connector 41 is separated from the female connector 6.

[0061] The above are preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
