Abstract
Description
Technical Field
[0001] This application relates to the field of wireless charging equipment technology, and in particular to a wireless charging station for wheeled robots. Background Technology
[0002] Wheeled robots, also known as unmanned transport vehicles, automated guided vehicles, or laser-guided vehicles, are equipped with an automatic guidance system that allows them to travel automatically along a predetermined route without the need for human guidance.
[0003] Wheeled robots typically use electricity to operate. There are two main ways to charge wheeled robots: one is manual charging, which involves manually operating the charging station to dock with the wheeled robot; the other is charging by automated equipment, which involves using an automated equipment's automatic alignment system to operate the charging station to dock with the wheeled robot. Both of these charging methods include wired charging and wireless charging.
[0004] Wheeled robots are capable of working 24 hours a day. If manual charging is used, people can accurately dock the charging pile with the wheeled robot, but this will require a lot of manpower. If automated equipment is used for charging, the automated equipment that can accurately dock the charging pile with the wheeled robot is very expensive and usually requires a large space. Using automated equipment with poor docking accuracy will cause the docking of the charging pile and the wheeled robot to deviate, which will reduce the efficiency of power absorption and transmission. Utility Model Content
[0005] The main purpose of this application is to provide a wireless charging station for wheeled robots, which aims to improve the high cost of existing charging stations when precise docking between the charging station and the wheeled robot is required.
[0006] To achieve the above objectives, this application proposes a wireless charging station for wheeled robots, comprising a mounting assembly, a first elastic element, a Z-axis movable assembly, at least two second elastic elements, an X-axis movable assembly, a wireless charging transmitter, and a guide assembly; wherein,
[0007] The installation components are fixedly installed.
[0008] The Z-axis movable component is slidably mounted on the mounting component along the Z-axis;
[0009] The first elastic element is elastically mounted between the Z-axis movable component and the mounting component, and causes the Z-axis movable component to have a tendency to move away from the mounting component;
[0010] The X-axis movable component is slidably mounted on the Z-axis movable component along the X-axis.
[0011] At least two second elastic members are respectively disposed on opposite sides of the X-axis movable component and between the Z-axis movable component, and elastically abut against opposite sides of the X-axis movable component;
[0012] The wireless charging transmitter is fixedly disposed on the side of the X-axis movable component opposite to the Z-axis movable component;
[0013] The guiding component includes a guide member fixedly disposed on the side of the wireless charging transmitter facing away from the X-axis movable component. The guide member has a guide opening that gradually increases in size from the side closer to the wireless charging transmitter to the side farther away from the wireless charging transmitter. The guide opening is used to slide and cooperate with the wheeled robot, so that the wireless charging transmitter, under the force of the wheeled robot, moves through the X-axis movable component and the Z-axis movable component to align with the wireless charging receiver of the wheeled robot.
[0014] In some embodiments of this application, the mounting assembly is provided with at least two first guide posts spaced apart, and both of the first guide posts extend along the Z-axis. The Z-axis movable assembly is slidably mounted on the at least two first guide posts.
[0015] In some embodiments of this application, the Z-axis movable component includes at least two first sliders corresponding one-to-one with at least two first guide posts, and at least two first sliders are slidably mounted on the corresponding first guide posts;
[0016] Both ends of each of the first guide posts are fixedly installed to the mounting assembly by a first fixing block. The number of the first elastic elements is at least two, and the first elastic element is a first spring sleeve, which is sleeved on the first guide post.
[0017] In some embodiments of this application, the mounting assembly is fixedly provided with a first guide rail, the first guide rail also extends along the Z-axis, and the Z-axis movable member is slidably mounted on the first guide rail by a slider.
[0018] In some embodiments of this application, the Z-axis movable component is provided with at least two second guide posts at intervals, and the at least two second guide posts extend along the X-axis, and the X-axis movable component is slidably mounted on the at least two second guide posts.
[0019] In some embodiments of this application, the X-axis movable component includes at least two second sliders corresponding one-to-one with at least two second guide posts, and the at least two second sliders are slidably mounted on the corresponding second guide posts;
[0020] Both ends of each second guide post are fixedly installed to the Z-axis movable assembly by a second fixing block. The number of at least two second elastic elements is twice the number of at least two second guide posts. The second elastic element is a second spring sleeve, which is sleeved on the second guide post.
[0021] In some embodiments of this application, the wheeled robot wireless charging station further includes a Y-axis adjustment assembly, which includes a mounting base and a lead screw. One side of the mounting base is slidably mounted on the X-axis movable assembly along the Y-axis, and the other side of the mounting base is fixedly provided with the wireless charging transmitter. The lead screw is rotatably mounted on the X-axis movable assembly and is also threadedly connected to the mounting base.
[0022] In some embodiments of this application, the X-axis movable component is fixedly provided with a third guide rail, the third guide rail also extends along the Y-axis, and the mounting base is slidably mounted on the third guide rail via a third slider.
[0023] In some embodiments of this application, the Y-axis adjustment assembly further includes a handle, which is fixedly connected to the lead screw and drives the lead screw to rotate under the action of an external force.
[0024] In some embodiments of this application, the guide includes two guide blocks, which are spaced apart along the X-axis. Each guide block has a guide surface on one side facing the other guide block, and the guide opening is formed between the guide surfaces of the two guide blocks.
[0025] The wireless charging station for wheeled robots provided in this application embodiment, through the above-described structural configuration, allows the wheeled robot to move towards the wireless charging station via an automatic guidance system when it needs charging. The wireless charging receiver of the wheeled robot contacts the guide port, effectively causing the guide port to slide. At this time, both the Z-axis and X-axis movable components are subjected to forces from the wheeled robot. The Z-axis movable component gradually moves along the Z-axis toward the interior of the mounting component, compressing the first elastic element. The first elastic element generates a reaction force that drives the guide port to slide and engage with the wireless charging receiver of the wheeled robot. Simultaneously, since the guide port gradually increases in size from the side closer to the wireless charging transmitter to the side farther away from the wireless charging transmitter, under the combined action of the sliding engagement between the guide port and the wireless charging receiver, the force of the first elastic element, and the force of the wheeled robot's movement, the X-axis movable component gradually moves along the X-axis, thereby aligning the wireless charging transmitter with the wireless charging receiver of the wheeled robot. With this configuration, the wheeled robot wireless charging station provided in the embodiments of this application can drive the X-axis movable component and the Z-axis movable component to move by sliding the wheeled robot with the guide port, so that the wireless charging transmitter end is aligned with the wireless charging receiver end of the wheeled robot. The energy absorption and transmission efficiency is high, so no manual operation is required and no expensive automated equipment is needed, which greatly reduces the cost.

[0038] An embodiment of this application provides a wireless charging station 100 for a wheeled robot, which is used to charge the wheeled robot. The wheeled robot, also known as an unmanned transport vehicle, an automated guided vehicle, or a laser-guided vehicle, is equipped with an automatic guidance system and can automatically travel along a predetermined route without human guidance. The wheeled robot is equipped with a wireless charging receiver, which is used to interface with the wireless charging transmitter 60 of the wireless charging station 100 to absorb electrical energy.
[0039] Please refer to Figures 1 to 3 The wheeled robot wireless charging station 100 includes a mounting component 10, a first elastic element 20, a Z-axis movable component 30, at least two second elastic elements 40, an X-axis movable component 50, a wireless charging transmitter 60, and a guide component 70. The mounting component 10 is fixedly installed in the charging area of the wheeled robot. It can be fixed to the ground with bolts, fixed to the wall with bolts, or placed on the ground with a counterweight.
[0040] Please refer to Figures 1 to 3 The Z-axis movable component 30 is slidably mounted on the mounting component 10 along the Z-axis. Specifically, a first guide rail can be fixedly provided on the mounting component 10, and the first guide rail also extends along the Z-axis. The Z-axis movable component is slidably mounted on the first guide rail via a slider. There is at least one first guide rail. Alternatively, at least two first guide posts 12 can be spaced apart on the mounting component 10, and both first guide posts 12 extend along the Z-axis. The Z-axis movable component 30 is slidably mounted on the at least two first guide posts 12. The first guide posts 12 can be cylindrical or prismatic. Preferably, the first guide posts 12 are cylindrical. At least two spaced first guide posts 12 allow the Z-axis movable component to slide more smoothly along the Z-axis. Figure 2 In the example, there are four first guide posts 12. Please refer to... Figure 1 The mounting assembly 10 includes a mounting bracket 11, and a Z-axis movable component 30 is slidably mounted on the mounting bracket 11 along the Z-axis. When the Z-axis movable component 30 is subjected to force, it moves along the Z-axis in a direction away from the mounting assembly 10, or moves along the Z-axis in a direction towards the interior of the mounting assembly 10 (i.e., the interior of the mounting bracket 11).
[0041] The first elastic element 20 is elastically mounted between the Z-axis movable assembly 30 and the mounting assembly 10, giving the Z-axis movable assembly 30 a tendency to move away from the mounting assembly 10. When the Z-axis movable assembly 30 moves along the Z-axis towards the interior of the mounting assembly 10 under the action of an external force, the first elastic element 20 is compressed and stores elastic potential energy. When the external force on the Z-axis movable assembly 30 disappears, the elastic potential energy stored in the first elastic element 20 is released, and the Z-axis movable assembly 30 will then be driven by the elastic force of the first elastic element 20 to move along the Z-axis away from the mounting assembly 10. The first elastic element 20 can be of various types, including but not limited to a sleeve spring, a spring sheet, and a spring ball.
[0042] Please refer to Figures 3 to 5 The X-axis movable component 50 is slidably mounted on the Z-axis movable component 30 along the X-axis. Specifically, a second guide rail can be fixedly provided on the Z-axis movable component 30, and the second guide rail also extends along the X-axis. The X-axis movable component is slidably mounted on the second guide rail via a slider. The number of second guide rails is at least one. Alternatively, at least two second guide posts 32 can be spaced apart on the Z-axis movable component 30, and both of the at least two second guide posts 32 extend along the X-axis. The X-axis movable component 50 is slidably mounted on the at least two second guide posts 32. The second guide posts 32 can be cylindrical or prismatic. Preferably, the second guide posts 32 are cylindrical. The at least two spaced second guide posts 32 can make the X-axis movable component slide more smoothly along the X-axis.
[0043] At least two second elastic elements 40 are respectively disposed on opposite sides of the X-axis movable component 50 and between the Z-axis movable component 30, and elastically abut against opposite sides of the X-axis movable component 50. It is important to emphasize that the elastic force exerted by the at least two second elastic elements 40 on opposite sides of the X-axis movable component 50 is almost identical. For example, if one elastic element abuts on one side of the X-axis movable component 50, there is also one elastic element abutting on the other side; or, for another example, if two elastic elements abut on one side of the X-axis movable component 50, there are also two elastic elements abutting on the other side. When the X-axis movable component 50 is subjected to force and moves along one side of the X-axis, it compresses the corresponding second elastic element 40, causing the corresponding second elastic element 40 to store elastic potential energy. When the external force disappears, the X-axis movable component 50, driven by the second elastic elements 40, moves along the other side of the X-axis.
[0044] The wireless charging transmitter 60 is fixedly disposed on the side of the X-axis movable component 50 opposite to the Z-axis movable component 30. The wireless charging transmitter 60 can be directly fixed on the X-axis movable component 50. However, considering that the height of the wireless charging receiver on the Y-axis may be different for different models of wheeled robots, in some examples, the wheeled robot wireless charging station 100 also includes a Y-axis adjustment component 80. The wireless charging transmitter 60 can also be mounted on the X-axis movable component 50 through the Y-axis adjustment component 80.
[0045] The Y-axis adjustment assembly 80 includes a mounting base 81 and a lead screw 82. One side of the mounting base 81 is slidably mounted on the X-axis movable assembly 50 along the Y-axis, and the other side of the mounting base 81 is fixedly mounted with a wireless charging transmitter 60. The lead screw 82 is rotatably mounted on the X-axis movable assembly 50 and is also threadedly connected to the mounting base 81. This configuration allows the height of the wireless charging transmitter 60 along the Y-axis to be adjusted by rotating the lead screw 82, enabling the wheeled robot wireless charging station 100 to be adapted to different models of wheeled robots, thus improving the compatibility of the wheeled robot wireless charging station 100. Furthermore, the lead screw 82 allows for stepless adjustment, improving adjustment accuracy.
[0046] The guide assembly 70 includes a guide member 71 fixedly disposed on the side of the wireless charging transmitter 60 away from the X-axis movable assembly 50. The guide member 71 forms a guide opening 712, which gradually increases in size from the side closer to the wireless charging transmitter 60 to the side farther away from the wireless charging transmitter 60. The guide opening 712 is used to slide and cooperate with the wheeled robot, so that the wireless charging transmitter 60 is aligned with the wireless charging receiver of the wheeled robot by moving through the X-axis movable assembly 50 and the Z-axis movable assembly 30 under the action of the wheeled robot.
[0047] The guide component 70 can be fixedly installed on the wireless charging transmitter 60, so that the guide member 71 is fixedly disposed on the side of the wireless charging transmitter 60 away from the X-axis movable component 50; the guide component 70 can be fixedly installed on the aforementioned Y-axis adjustment component 80, i.e., the aforementioned mounting base 81, so that the guide member 71 is fixedly disposed on the side of the wireless charging transmitter 60 away from the X-axis movable component 50. Specifically, the guide component 70 also includes a connecting plate 72 and a partition plate 73. The connecting plate 72 is fixedly connected to the mounting base 81 and is located on the periphery of the wireless charging transmitter 60 to protect the wireless transmitter. The partition plate 73 is fixedly connected to the side of the connecting plate 72 away from the mounting base 81, thereby protecting the wireless transmitter. The aforementioned guide member 71 is fixedly disposed on the partition plate 73.
[0048] The wireless charging station 100 for wheeled robots provided in this application embodiment, through the above-described structural configuration, allows the wheeled robot to move towards the wireless charging station 100 via an automatic guidance system when it needs charging. The wireless charging receiver of the wheeled robot contacts the guide port 712, effectively causing the guide port 712 to slide. At this time, both the Z-axis movable component 30 and the X-axis movable component 50 are subjected to forces from the wheeled robot. The Z-axis movable component 30 gradually moves along the Z-axis toward the interior of the mounting component 10, compressing the first elastic element 20. The first elastic element 20 generates a reaction force that drives the guide port 712 to slide and engage with the wireless charging receiver of the wheeled robot. Simultaneously, since the guide port 712 gradually increases in size from the side closer to the wireless charging transmitter 60 to the side farther away from the wireless charging transmitter 60, under the combined action of the sliding engagement guidance of the guide port 712 and the wireless charging receiver, the force of the first elastic element 20, and the force of the wheeled robot's movement, the X-axis movable component 50 gradually moves along the X-axis, thereby aligning the wireless charging transmitter 60 with the wireless charging receiver of the wheeled robot. With this configuration, the wheeled robot wireless charging station 100 provided in the embodiments of this application can drive the X-axis movable component 50 and the Z-axis movable component 30 to move through the sliding cooperation between the wheeled robot and the guide port 712, so that the wireless charging transmitter 60 is aligned with the wireless charging receiver of the wheeled robot. The energy absorption and transmission efficiency is high, so no manual operation is required and no expensive automated equipment is needed, which greatly reduces the cost.
[0049] In some examples, such as Figures 2 to 5 As shown, the Z-axis movable assembly 30 includes at least two first sliders 31 corresponding to at least two first guide posts 12, with each first slider 31 slidably mounted on its corresponding first guide post 12. Both ends of each first guide post 12 are fixedly mounted to the mounting assembly 10 via first fixing blocks 13. There are at least two first elastic elements 20, each a first spring sleeve, which is fitted onto the first guide post 12. This arrangement facilitates the installation of the first spring sleeves, which are common standard parts available on the market, making them easy to purchase and reducing the manufacturing cost of the wheeled robot wireless charging station 100.
[0050] In some examples, such as Figures 2 to 5As shown, the X-axis movable assembly 50 includes at least two second sliders 51 corresponding to at least two second guide posts 32, and both second sliders 51 are slidably mounted on their respective second guide posts 32. Both ends of each second guide post 32 are fixedly mounted to the Z-axis movable assembly 30 via second fixing blocks 33. The number of at least two second elastic elements 40 is twice the number of the at least two second guide posts 32. The second elastic element 40 is a second spring sleeve, which is sleeved on the second guide post 32. This arrangement facilitates the installation of the second spring sleeve, and since the spring sleeve is a common standard part on the market, it is easy to purchase, thereby reducing the manufacturing cost of the wheeled robot wireless charging station 100.
[0051] In some examples, such as Figures 3 to 5 As shown, the X-axis movable component 50 is fixedly equipped with a third guide rail 52, which also extends along the Y-axis. The mounting base 81 is slidably mounted on the third guide rail 52 via a third slider 811. This arrangement aims to make the movement of the mounting base 81 along the Y-axis more stable and reduce the jerking sensation when adjusting the height of the wireless transmitter on the Y-axis.
[0052] In some examples, such as Figure 4 and Figure 5 As shown, the Y-axis adjustment assembly 80 also includes a handle 83, which is fixedly connected to the lead screw 82 and drives the lead screw 82 to rotate under external force. This design is intended to facilitate adjustment operations by the worker using the handle 83.
[0053] In some examples, such as Figures 1 to 3 As shown, the guide member 71 includes two guide blocks 711, which are spaced apart along the X-axis. Specifically, the two guide blocks 711 are spaced apart on the partition 73 along the X-axis. Each guide block 711 has a guide surface 7111 on one side facing the other guide block 711, and a guide opening 712 is formed between the guide surfaces 7111 of the two guide blocks 711. This arrangement allows for smoother sliding contact between the wireless charging receiver of the wheeled robot and the guide surface 7111, resulting in better guidance.
[0054] The above description is merely an optional embodiment of this application and does not limit the patent scope of this application.
