Description

Technical Field

[0001] This utility model belongs to the field of wireless charging technology, specifically referring to a wireless charging device for robots. Background Technology

[0002] With the development of artificial intelligence and Internet of Things technologies, the application of robots in industrial manufacturing, logistics and warehousing, home services and healthcare has seen explosive growth, and the demand for wireless charging technology for robots has also increased dramatically.

[0003] Traditional wireless charging devices for robots generally adopt a fixed structure design, with their wireless charging coils exposed, which has the following drawbacks:

[0004] 1. Lacking an automatic storage function, the wireless charging coil is exposed to the outside for a long time, making it susceptible to dust, moisture corrosion or mechanical impact damage, resulting in reduced charging efficiency or equipment failure;

[0005] 2. Due to navigation errors and uneven ground conditions, the robot's docking position often deviates in both the horizontal and vertical directions. Existing devices mostly rely on manual adjustment or complex sensor positioning, which is inflexible and costly. Utility Model Content

[0006] To address the aforementioned problems of traditional robot wireless charging devices lacking automatic retraction of the wireless charging coil and poor adaptability to robot charging locations, this invention provides a robot wireless charging device.

[0007] To achieve the above functions, the technical solution adopted by this utility model is as follows: A wireless charging device for a robot includes a base, a charging box with a side opening, and a wireless charging coil. Two sets of side supports are symmetrically arranged on the side of the base. A horizontal adjustment groove is opened on the opposite inner side wall of the two sets of side supports. An adjustment component is arranged in the horizontal adjustment groove. The charging box is fixedly installed on the top of the base. Two sets of sliding doors are symmetrically slidably installed at the side opening of the charging box. A storage component is arranged inside the charging box. The storage component is connected to a rectangular frame. A vertical groove is opened in the rectangular frame. A height adjustment component is arranged on the rectangular frame.

[0008] The height adjustment assembly includes a rotary motor fixed to the top of a rectangular frame, a threaded rod vertically arranged in a vertical groove, and a movable block threaded onto the threaded rod. The top end of the threaded rod is connected to the output end of the rotary motor, and the bottom end is connected to the rectangular frame through a bearing. The wireless charging coil is fixed to the side of the movable block.

[0009] As a preferred technical solution of this utility model, the storage component includes a reciprocating cylinder horizontally fixed to the inner side wall of the charging box and an auxiliary telescopic rod parallel to the reciprocating cylinder. The piston end of the reciprocating cylinder is fixed to the side wall of the rectangular frame, and the auxiliary telescopic rods are symmetrically distributed on the upper and lower sides of the reciprocating cylinder. The two ends of each set of auxiliary telescopic rods are respectively fixed to the inner side wall of the charging box and the side wall of the rectangular frame.

[0010] As a preferred embodiment of the present invention, the adjusting assembly includes a telescopic cylinder fixed to the inner side of the transverse adjusting groove and a push plate connected to the piston rod of the telescopic cylinder.

[0011] As a preferred technical solution of this utility model, the top of the base is provided with rectangular grooves symmetrically along the length direction, and a horizontal push-pull cylinder is fixed in the rectangular groove. The piston end of the push-pull cylinder is fixedly connected to the bottom of the push-pull door through a connecting block.

[0012] As a preferred technical solution of this utility model, the top of the charging box is provided with a horizontal sliding groove, and the top walls of the two sets of sliding doors are fixed with limit strips, which are slidably arranged in the horizontal sliding groove.

[0013] As a preferred technical solution of this utility model, the bottom of the base and the side support are evenly provided with movable wheels with braking function.

[0014] Compared with the prior art, the present invention achieves the following beneficial effects by adopting the above structure:

[0015] 1. Through the coordinated design of the storage component, the push-pull cylinder, and the push-pull door, the wireless charging coil can be driven by the reciprocating cylinder in the storage component to be stored inside the charging box and protected by the push-pull door, thus solving the problem that traditional external wireless charging coils are easily damaged by dust, moisture, and impact.

[0016] 2. By combining the distance adjustment component and the height adjustment component, the telescopic cylinder drives the push plate to adjust the horizontal position of the robot charging dock, and the threaded rod drives the wireless charging coil to rise and fall. This automatically adapts to the horizontal and vertical docking position deviations caused by navigation errors and uneven ground, improving the flexibility and accuracy of the robot's wireless charging alignment.

Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances. The present invention will be further described in detail below with reference to the accompanying drawings.

[0025] like Figure 1-4As shown, this utility model provides a wireless charging device for robots, including a base 1, a charging box 2 with a side opening, and a wireless charging coil 3. Two sets of side supports 4 are symmetrically arranged on the side of the base 1. Horizontal adjustment grooves 5 are opened on the opposite inner sidewalls of the two sets of side supports 4. An adjustment component 6 is arranged in the horizontal adjustment groove 5. Moving wheels 23 with braking function are evenly arranged at the bottom of the base 1 and the side supports 4, which facilitates the movement of the device according to usage requirements and fixes its position through the braking mechanism. The charging box 2 is fixedly installed on the top of the base 1. Two sets of sliding doors 7 are symmetrically slidably installed at the side opening of the charging box 2. A storage component 8 is arranged inside the charging box 2. The storage component 8 is connected to a rectangular frame 9. A vertical groove 10 is opened in the rectangular frame 9. A height adjustment component 11 is arranged on the rectangular frame 9.

[0026] The height adjustment assembly 11 includes a rotary motor 12 fixed to the top of the rectangular frame 9, a threaded rod 13 vertically arranged in the vertical groove 10, and a moving block 14 threadedly connected to the threaded rod 13. The top end of the threaded rod 13 is connected to the output end of the rotary motor 12, and the bottom end is connected to the rectangular frame 9 through a bearing. The wireless charging coil 3 is fixed to the side of the moving block 14. When the robot reaches the charging position, the rotary motor 12 is controlled to rotate according to the height of the robot's charging interface, thereby driving the threaded rod 13 to rotate. Under the action of the threaded transmission principle, the moving block 14 will move up and down along the threaded rod 13 in the vertical groove 10, thereby driving the wireless charging coil 3 to adjust to a position that matches the height of the robot's charging interface, realizing the wireless charging needs of robots of different heights and enhancing the versatility of the charging device.

[0027] like Figure 1 , 3 As shown in Figure 4, the storage assembly 8 includes a reciprocating cylinder 15 horizontally fixed to the inner wall of the charging housing 2 and an auxiliary telescopic rod 16 parallel to the reciprocating cylinder 15. The piston end of the reciprocating cylinder 15 is fixed to the side wall of the rectangular frame 9. The auxiliary telescopic rods 16 are symmetrically distributed on the upper and lower sides of the reciprocating cylinder 15. The two ends of each set of auxiliary telescopic rods 16 are respectively fixed to the inner wall of the charging housing 2 and the side wall of the rectangular frame 9. The auxiliary telescopic rods 16 play an auxiliary support and guiding role, ensuring that the rectangular frame 9 is stable during movement. When the robot needs to be charged, the piston of the reciprocating cylinder 15 extends, pushing the rectangular frame 9 and the wireless charging coil 3 out of the charging housing 2 to the working position. After charging is completed, the piston retracts, driving the rectangular frame 9 and the wireless charging coil 3 back into the housing, thereby reducing the corrosion of the wireless charging coil 3 by external dust and moisture and solving the problem of easy damage to the traditional externally mounted wireless charging coil 3.

[0028] like Figure 1-3As shown, the distance adjustment assembly 6 includes a telescopic cylinder 17 fixed inside the transverse adjustment groove 5 and a push plate 18 connected to the piston rod of the telescopic cylinder 17. The push plate 18 can slide along the transverse adjustment groove 5 and be completely retracted therein. When the robot approaches the charging device, the piston rod of the telescopic cylinder 17 is extended by controlling it, which drives the push plate 18 to push the robot towards the center of the device, thereby adjusting the horizontal distance between the robot and the wireless charging coil 3. After charging is completed, the piston rod retracts and the push plate 18 is retracted into the transverse adjustment groove 5, without affecting the robot's departure. This is convenient for adapting to robots of different sizes and with deviations in their parking positions, ensuring that the two maintain a suitable distance during wireless charging.

[0029] like Figure 1 , 3 As shown in Figure 4, the top of the base 1 has symmetrical rectangular grooves 19 along its length. A horizontal push-pull cylinder 20 is fixed inside the rectangular groove 19. The piston end of the push-pull cylinder 20 is fixedly connected to the bottom of the push-pull door 7 through a connecting block. When the robot needs to be charged, the push-pull cylinder 20 pushes the push-pull door 7 to open, exposing the internal wireless charging coil 3. After charging is completed, the push-pull door 7 closes, enclosing the wireless charging coil 3 inside the charging box 2, which serves as a protective measure to prevent the wireless charging coil 3 from being exposed to the external environment. The top of the charging box 2 has a horizontal sliding groove 21. Limiting strips 22 are fixed to the top walls of the two sets of push-pull doors 7. The limiting strips 22 are slidably disposed in the horizontal sliding groove 21. The limiting strips 22 slide in the horizontal sliding groove 21, which serves as a guide and limiter, ensuring that the push-pull door 7 will not deviate or jam during the sliding process, and ensuring smooth opening and closing of the door.

[0030] In practical use, the device is first moved to the predetermined position and locked by the moving wheels 23. When the robot approaches, the telescopic cylinder 17 drives the push plate 18 to push the robot to a suitable horizontal position. At the same time, the rotary motor 12 drives the threaded rod 13 to raise and lower the wireless charging coil 3 to a height that matches the robot's charging interface. Then, the push-pull cylinder 20 drives the push-pull door 7 to open, and the reciprocating cylinder 15 pushes the wireless charging coil 3 out of the box to start charging. After charging is completed, the wireless charging coil 3 retracts into the box, the push-pull door 7 closes, and the push plate 18 is also stored in the horizontal adjustment slot 5.

[0031] The present invention and its embodiments have been described above. This description is not restrictive, and the accompanying drawings are only one embodiment of the present invention; the actual structure is not limited thereto. In conclusion, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the inventive spirit of the present invention, such designs should fall within the protection scope of the present invention.
