Description

Technical Field

[0001] This utility model relates to the field of wireless power transmission technology, and in particular to a humanoid robot adaptive positioning wireless charging base. Background Technology

[0002] Wireless charging for robots is a technology that eliminates the need for cables, breaking physical constraints and allowing robots to transfer energy to their batteries without being restricted by cables. This enables robots to move and perform tasks more freely, replenish energy during tasks, and effectively improve work efficiency.

[0003] However, existing traditional wireless charging requires extremely high coil alignment accuracy, requiring millimeter-level matching for efficient power transmission. Humanoid robots are affected by gait errors, slight ground tilt, limb sway, etc., making it difficult to accurately calibrate when docking for charging. If the coil is misaligned due to body tilt or unstable standing posture, not only will the transmission efficiency drop sharply, but charging will also be interrupted directly if the deviation exceeds the limit. Utility Model Content

[0004] In order to overcome the technical problems existing in the prior art, this utility model provides a humanoid robot adaptive positioning wireless charging base.

[0005] The technical implementation scheme of this utility model is as follows: A humanoid robot adaptive positioning wireless charging base includes a base, a support shell, pressure sensors, a return spring, a contact frame, a soft rubber pad, a mounting base, a motor, a rotating shaft, and a wireless charging module. The base is fixedly connected to the bottom of the base. A hollow support shell is provided on the front side of the base. Four pressure sensors are fixedly connected to the support shell. The four pressure sensors are arranged symmetrically vertically to detect the pressure signal received by the contact frame and determine the docking position of the robot. A return spring is provided on the support shell. The contact frame is fixedly connected to the front side of the return spring. The contact frame is elastically connected to the support shell through the return spring. A soft rubber pad is fixedly connected to the outer side of the contact frame, and a mounting base is fixedly connected to the front side of the base. The mounting base is located inside the support shell, and a motor is fixedly connected to the mounting base. A rotating shaft is rotatably connected to the mounting base, and the output shaft of the motor is fixedly connected to the rotating shaft. A control system is provided on the base, and a pressure sensor is electrically connected to the motor through the control system to drive the rotating shaft to rotate. A wireless charging module is fixedly connected to the rotating shaft, and the support shell is fixedly connected to the bottom of the wireless charging module. The support shell rotates synchronously with the wireless charging module. The wireless charging module is located inside the contact frame. The motor drives the rotating shaft to rotate, thereby causing the wireless charging module to rotate, realizing adaptive adjustment of the charging angle.

[0006] Furthermore, it also includes a first shielding cover, an elastic element, and a second shielding cover. The first shielding cover is fixedly connected to the outside of the support shell. A sliding groove is provided on the first shielding cover, and the second shielding cover is slidably connected in the sliding groove. An elastic element connects the first shielding cover and the second shielding cover. The first shielding cover and the second shielding cover are made of metal and are used to shield electromagnetic radiation during wireless charging.

[0007] Furthermore, it also includes a telescopic pad. A telescopic pad is provided between the outer side of the wireless charging module and the inner side of the contact frame. The telescopic pad is used to cover the gap between the two to prevent dust from entering or electromagnetic radiation from leaking out.

[0008] Furthermore, it also includes a sponge pad, which is fixedly connected to the front side of the contact frame to reduce scratches during contact.

[0009] Furthermore, it also includes identification stickers, which are fixedly attached to the base to help the robot identify the location of the charging base.

[0010] Furthermore, it also includes indicator lights, which are fixedly connected to the base to show the charging status.

[0011] The present invention has the following advantages: 1. By triggering the pressure sensor through the force between the robot and the contact frame, the signal is fed back to the control system, which controls the motor to drive the wireless charging module to rotate, thereby achieving adaptive calibration of the charging angle and ensuring the precise alignment of the wireless charging module with the robot interface, thus ensuring efficient and stable charging.

[0012] 2. The robot comes into contact with the second shielding cover, and the second shielding cover slides inside the first shielding cover along with the elastic element. The rotation of the wireless charging module drives the first shielding cover to rotate synchronously, which plays a role in adapting to the rotation trajectory of the wireless charging module, so as to achieve the effect of always fitting the module and continuously shielding electromagnetic radiation.

[0013] 3. The flexible structure, which rotates with the wireless charging module, provides a flexible shielding effect by using a telescopic pad between the wireless charging module and the contact frame to prevent dust intrusion and provide additional shielding against electromagnetic radiation.

Detailed Implementation

[0020] References to embodiments herein mean that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of the present invention. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0021] Example: A humanoid robot adaptive positioning wireless charging base, such as... Figure 1-4 As shown, the system includes a base 1, a base 2, a support shell 3, pressure sensors 4, a return spring 5, a contact frame 6, a soft rubber pad 7, a mounting base 8, a motor 9, a rotating shaft 10, and a wireless charging module 11. The base 2 is fixedly connected to the bottom of the base 1, and the base 2 is mounted on the ground with its top surface flush with the ground. A hollow support shell 3 is located on the front side of the base 1. Four pressure sensors 4 are fixedly connected to the support shell 3, located symmetrically on the upper and lower sides of the support shell 3, and are used to detect the pressure signal received by the contact frame 6 to determine the robot's docking position. A return spring 5 is located on the support shell 3, and the contact frame 6 is fixedly connected to the front side of the return spring 5. The contact frame 6 is elastically connected to the support shell 3 through the return spring 5. A soft rubber pad 7 is fixedly connected to the outer side of the contact frame 6. A mounting base 8 is fixedly connected to the front side of the base 1. The mounting base 8 is located inside the support shell 3. A motor 9 is fixedly connected to the mounting base 8. A rotating shaft 10 is rotatably connected to the mounting base 8. The output shaft of the motor 9 is fixedly connected to the rotating shaft 10. A control system is provided on the base 1. The pressure sensor 4 is electrically connected to the motor 9 through the control system to drive the rotating shaft 10 to rotate. A wireless charging module 11 is fixedly connected to the rotating shaft 10. The support shell 3 is fixedly connected to the bottom of the wireless charging module 11. The support shell 3 rotates synchronously with the wireless charging module 11. The wireless charging module 11 is located inside the contact frame 6. The motor 9 drives the rotating shaft 10 to rotate, thereby causing the wireless charging module 11 to rotate, realizing adaptive adjustment of the charging angle.

[0022] like Figure 5 As shown, it also includes a first shielding cover 12, an elastic element 13, and a second shielding cover 14. The first shielding cover 12 is fixedly connected to the outside of the support shell 3. A sliding groove is provided on the first shielding cover 12, and the second shielding cover 14 is slidably connected in the sliding groove. An elastic element 13 is connected between the first shielding cover 12 and the second shielding cover 14. The first shielding cover 12 and the second shielding cover 14 are made of metal and are used to shield electromagnetic radiation during wireless charging.

[0023] like Figure 1 and Figure 5 As shown, it also includes a telescopic pad 15. A telescopic pad 15 is provided between the outer side of the wireless charging module 11 and the inner side of the contact frame 6. The telescopic pad 15 is used to cover the gap between the two to prevent dust from entering or electromagnetic radiation from leaking out.

[0024] like Figure 1 and Figure 5 As shown, it also includes a sponge pad 16. The sponge pad 16 is fixedly connected to the front side of the contact frame 6. The sponge pad 16 is used to reduce scratches generated during contact.

[0025] like Figure 1 As shown, it also includes a label 17, which is fixedly connected to the base 2 to help the robot identify the position of the charging base 2.

[0026] like Figure 1 As shown, it also includes an indicator light 18, which is fixedly connected to the base 1 to display the charging status.

[0027] The humanoid robot identifies the label 17 on the base 2 using its vision system. After determining the position of the charging base 2, it gradually approaches it along a preset path. The charging port on the robot's back is aligned with the center of the contact frame 6. The robot moves slowly until its back contacts the sponge pad 16 and the second shield 14 on the front side of the contact frame 6. The sponge pad 16 reduces scratches caused by hard contact. After being subjected to force, the contact frame 6 and the second shield 14 move backward, compressing the return spring 5. The four pressure sensors 4 on the support shell 3 are evenly distributed. If the robot leans forward, the pressure on the contact frame 6 in the area below its back increases, squeezing the contact... The reset spring 5 below the contact frame 6 causes the contact frame 6 to tilt forward. Simultaneously, the pressure sensor 4 detects the pressure on the contact frame 6 and feeds a signal back to the control system, driving the motor 9 to rotate clockwise. The motor 9 then rotates the rotating shaft 10, causing the wireless charging module 11, fixed on the rotating shaft 10, to rotate synchronously. This causes the wireless charging module 11 to tilt forward, and the wireless charging module 11 drives the support shell 3 to rotate synchronously until the pressure sensor 4 inside the support shell 3 experiences the same pressure. At this point, the motor 9 stops rotating, and the wireless charging module 11 connects to the robot charging interface. With the ends aligned, the wireless charging module 11 will drive the first protective cover to rotate synchronously. After the second shielding cover 14 contacts the robot's back, it will be forced backward to press against the elastic element 13, avoiding hard contact between the second shielding cover 14 and the robot. During the process, the second shielding cover 14 maintains its electromagnetic shielding effect. After the angle is aligned, the wireless charging module 11 will automatically start to charge the robot. The contact frame 6 will always be in close contact with the robot's back under the action of the return spring 5. The soft rubber pad 7 will buffer vibration, and the sponge pad 16 will prevent wear from long-term contact, ensuring stable contact during charging. The first shielding cover 12 and the second shielding cover 13... 4 is made of metal. Utilizing the metal's characteristics of reflecting and absorbing electromagnetic waves, it blocks the electromagnetic radiation generated by the transmitting coil during wireless charging from spreading outward, reducing interference with other electronic components of the robot. After receiving the full charge signal, the robot slowly moves forward, disengaging from the contact frame 6. The contact frame 6 loses external force and resets forward under the action of the reset spring 5. The pressure sensor 4 experiences zero force, and the sponge pad 16 and soft rubber pad 7 return to their initial state. The motor 9 drives the wireless charging module 11 to rotate back to its initial angle and then stops. The first shield 12 and the second shield 14 reset and adhere under the action of the elastic element 13.

[0028] The telescopic pad 15 can cover the gap between the wireless charging module 11 and the contact frame 6 to prevent dust from entering and affecting the coil performance. At the same time, it helps to shield electromagnetic radiation leakage. The label 17 helps the robot identify the position of the base 2 through visual or infrared sensors. The indicator light 18 uses different colors to reflect the charging status.

All equivalent substitutions made within the principles of this utility model should be included within the protection scope of this utility model.
