Description

Technical Field

[0001] This utility model relates to the field of robot auxiliary equipment technology, and in particular to a foldable humanoid robot wireless charging transmitter bracket. Background Technology

[0002] In recent years, with the deep integration of artificial intelligence technology and the robotics industry, the application of humanoid robots in fields such as industrial manufacturing, medical services, logistics and transportation, and home services has shown a rapid expansion trend. Their functions are evolving from single-task operations to diversified and intelligent ones, placing higher demands on the adaptability and convenience of supporting equipment. Among these, autonomous charging technology, as a core component ensuring the continuous operation capability of robots, has become a key area of ​​research and development in the industry.

[0003] Currently, mainstream robot manufacturers are continuously advancing technological innovation in the field of autonomous charging. Wireless charging technology, with its advantages of non-contact energy transfer, high safety, and strong environmental adaptability, is gradually becoming the mainstream solution. Compared with the problems of plug wear and poor compatibility of traditional wired charging interfaces, wireless charging can achieve universal energy supply through electromagnetic induction or magnetic field resonance, effectively reducing equipment maintenance costs.

[0004] However, existing wireless charging transmitter devices still have significant limitations in practical applications: due to the large differences in the installation height of the charging receivers of different models of humanoid robots, the transmitter brackets need to be customized according to the specific models; when the robot's working area is adjusted or the model is changed in the factory, the transmitter brackets need to be repeatedly disassembled and reassembled to adjust the height, which is inefficient and easily affects the accuracy of the equipment due to mechanical adjustments. Utility Model Content

[0005] To overcome the shortcomings of insufficient adaptability and poor ease of assembly and disassembly, this utility model provides a foldable wireless charging transmitter bracket for humanoid robots.

[0006] A foldable humanoid robot wireless charging transmitter bracket includes a base and a rotating frame. A limiting frame is connected to the front end of the base. The rotating frame, with two rods, is located inside the base and its front end is rotatably connected to the base. A plug rod is slidably connected to the rotating frame. The limiting frame has limiting holes that slidably connect to the plug rod, and the limiting frame and rotating frame are mutually limiting. A sliding frame is slidably connected inside the rotating frame, and a wireless charger is mounted on the sliding frame. Several square holes are opened on the two rods of the sliding frame. A mounting base is connected to the right end of the rotating frame. A gear is rotatably connected to the mounting base. A rotating shaft is coaxially connected to the gear shaft. A torsion spring is sleeved on the rotating shaft. One end of the torsion spring is connected to the mounting base, and the other end is connected to the rotating shaft. A rack is slidably connected to the ends of both rods of the rotating frame, and the rack meshes with the gear. A locking block is slidably connected to the end of the rotating frame, and the rack is fixedly connected to the locking block. The locking block is mutually limiting with the sliding frame through the square holes. An auxiliary movement component is provided at the bottom of the base.

[0007] Furthermore, the movable component includes a telescopic rod, which is composed of circular tubes that slide against each other without disengaging. The ends of the circular rods are connected to the bottom of the base, and the ends of the circular tubes of the telescopic rods are connected to a connecting seat. A movable wheel is installed at the lower end of the connecting seat.

[0008] Furthermore, a connecting rod connects the two racks that slide within the rotating frame.

[0009] Furthermore, a torsion block is connected to the end of the rotating shaft.

[0010] Furthermore, a handle is connected to the rear end of the base.

[0011] Furthermore, a rubber pad is laid inside the base, and the rubber pad covers the rotating frame.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. By using the square hole of the sliding frame to cooperate with the inclined surface of the card block, when rising, the inclined surface is squeezed to push the card block to the right. After stopping, the card block moves to the left and inserts into the square hole to form a rigid limit, realizing the automatic locking of the wireless charger in multiple positions, adapting to different robot heights, and improving compatibility and efficiency.

[0014] 2. The hinged connection between the rotating frame and the limiting frame, along with the interference fit between the insertion rod and the limiting hole, restricts the rotation of the rotating frame by radial friction of the insertion rod when unfolded. When folded, the insertion rod is pulled out and the rotating frame is embedded into the base and makes elastic contact with the rubber pad, allowing the bracket to complete the conversion between working and storage states in a short time, thus enhancing portability.

Detailed Implementation

[0021] The embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0022] Example: Foldable wireless charging transmitter stand for humanoid robots, such as... Figures 1-5As shown, the device includes a base 1, a limiting frame 101, a rotating frame 2, a plug rod 3, a sliding frame 4, a wireless charger 5, a mounting base 6, a rotating shaft 7, a torsion spring 8, a gear 9, a rack 10, a locking block 11, and a moving assembly. The limiting frame 101 is connected to the front end of the base 1. The rotating frame 2, with its two rods, is located inside the base 1, and its front end is rotatably connected to the base 1. The plug rod 3 is slidably connected to the rotating frame 2. The limiting frame 101 has a limiting hole that slidably connects to the plug rod 3. The plug rod 3 is interference-fitted with the limiting hole of the limiting frame 101. The limiting frame 101 is in a limiting fit with the rotating frame 2. The sliding frame 4 is slidably connected inside the rotating frame 2. The wireless charger 5 is installed on the sliding frame 4. The two rods of the sliding frame 4 have several square holes 40. 1. A mounting base 6 is connected to the right side of the end of the rotating frame 2. A gear 9 is rotatably connected to the mounting base 6. A rotating shaft 7 is coaxially connected to the shaft of the gear 9. A torsion spring 8 is sleeved on the rotating shaft 7. One end of the torsion spring 8 is connected to the mounting base 6, and the other end is connected to the rotating shaft 7. A rack 10 is slidably connected to the ends of the two rods of the rotating frame 2. The rack 10 meshes with the gear 9. A locking block 11 is slidably connected to the end of the rotating frame 2. The rack 10 and the locking block 11 are fixedly connected. The locking block 11 is limited to the sliding frame 4 through the square hole 401. The bottom side of the part of the locking block 11 inserted into the square hole 401 is set as an inclined surface. Both the rack 10 and the locking block 11 are provided with a "convex" structure, which restricts the sliding to only left and right. A moving component for auxiliary movement is provided at the bottom of the base 1.

[0023] like Figure 2 and Figure 5 As shown, the moving component includes a telescopic rod 12, a connecting seat 13, and a moving wheel 14. The telescopic rod 12 is composed of round rods and round tubes that slide against each other without disengaging. The telescopic rod 12 achieves a buffering function through damping material in the sealed structure. The round rod end of the telescopic rod 12 is connected to the bottom of the base 1, and the round tube end of the telescopic rod 12 is connected to the connecting seat 13. The lower end of the connecting seat 13 is equipped with a moving wheel 14. The moving wheel 14 is equipped with a self-locking device to achieve fixation. It unlocks when it needs to move and automatically brakes when it is in position.

[0024] like Figure 1 and Figure 2 As shown, it also includes a connecting rod 15. The two racks 10 sliding inside the rotating frame 2 are connected by the connecting rod 15, so that the racks 10 slide synchronously.

[0025] like Figure 3 As shown, it also includes a torsion block 16, which is connected to the end of the rotating shaft 7. The torsion block 16 is provided with two extended force-bearing plates.

[0026] like Figure 2 and Figure 5 As shown, it also includes a handle 17, which is connected to the rear end of the base 1.

[0027] like Figure 2As shown, it also includes a rubber pad 18. The base 1 is lined with a rubber pad 18, which provides flexible support for the folded rotating frame 2.

[0028] When the staff needs to move the stand, they first release the self-locking function of the moving wheel 14 by foot pedal or manually. Then, they hold the handle 17 and push the base 1. At this time, the round rod of the telescopic rod 12 slides relative to the round tube. The built-in damping structure absorbs the vibration energy caused by uneven road surfaces through friction or hydraulic pressure, effectively suppressing the shaking of the base 1. After moving to the target position, the staff triggers the self-locking switch of the moving wheel 14 to complete the stable positioning of the stand, ensuring that the wireless charger 5 remains stable during movement and does not need to be recalibrated after reaching the charging area.

[0029] During the charging preparation stage, the staff removes the plug rod 3 and then pulls the rear end of the rotating frame 2 upward. The rotating frame 2 rotates around the front hinge as the axis until the bottom is completely in contact with the inner surface of the limiting frame 101. At this time, the staff reinserts the plug rod 3 into the through hole at the rear of the rotating frame 2. The outer wall of the plug rod 3 forms an interference fit with the hole wall of the limiting frame 101, preventing the rotating frame 2 from rotating back. This allows the wireless charger 5 to change from the storage state to a vertical working posture, providing basic support for subsequent height adjustment.

[0030] Based on the robot's charging height requirements, the operator lifts the top of the sliding frame 4 upwards. The edge of the square hole 401 in the sliding frame 4 continuously presses against the inclined surface of the locking block 11, generating a component force perpendicular to the inclined surface that pushes the locking block 11 to the right. The locking block 11 drives the gear 9 to rotate clockwise via the rack 10. The rotating shaft 7, coaxial with the gear 9, rotates synchronously and torsional the torsion spring 8, storing elastic potential energy. When the sliding frame 4 is raised to the next position, the left end of the locking block 11 aligns with the square hole 401. The torsion spring 8 releases energy to drive the gear 9 to rotate counterclockwise. The gear 9, via the rack 10, pulls the locking block 11 to the left and inserts it into the square hole 401. During this process, the top surface of the locking block 11 forms a rigid limit with the upper edge of the square hole 401, effectively bearing the weight of the sliding frame 4 and the wireless charger 5, maintaining the stability of the adjusted height.

[0031] When the charging height needs to be lowered, the operator rotates the torsion block 16 with one hand, driving the rotating shaft 7 to rotate clockwise, which in turn drives the gear 9 to rotate synchronously. The single gear 9, through the connecting rod 15, pushes the racks 10 on both sides to move to the right, causing the locking block 11 connected to the end of the rack 10 to disengage from the square hole 401 of the sliding frame 4. At this point, the sliding frame 4 loses the restraint of the locking block 11 and can slide freely under gravity. After the operator adjusts the sliding frame 4 to the target height with their other hand, they release the torsion block 16. The torsion spring 8 drives the gear 9 to rotate counterclockwise, and the rack 10 moves to the left, causing the locking block 11 to re-insert into the corresponding square hole 401, completing the height locking. This achieves precise lowering of the charging position, adapting to the docking needs of robots at different heights.

[0032] During the storage phase, the staff first unlocks the locking block 11 using the twisting block 16, allowing the sliding frame 4 to fall completely to the bottom of the rotating frame 2. Then, the fixing rod 3 is pulled out, and the top of the rotating frame 2 is pushed backward. The rotating frame 2 rotates backward around the hinge axis until it is fully embedded in the inner cavity of the base 1. At this point, the outer surface of the rotating frame 2 contacts the rubber pad 18 laid inside the base 1. The rubber pad 18 undergoes elastic deformation under pressure, filling the gap between the rotating frame 2 and the base 1, forming a buffer protective layer. The staff then inserts the rod 3 into the through hole at the front of the rotating frame 2 or the pre-drilled hole in the limiting frame 101. This process completes the conversion of the bracket from its working state to its stored state, ensuring structural stability and protection from collision damage during transportation.
