Description

Technical Field

[0001] This invention belongs to the field of charging station technology, and specifically relates to a charging structure that can be automatically adjusted. Background Technology

[0002] Existing charging stations use fixed charging electrodes. When encountering uneven ground, there's a height difference between the robot's charging electrodes and the station's electrodes. This can lead to incomplete or nonexistent contact between the two electrodes, causing unstable charging or failure to charge during autonomous charging. In extreme cases, the two sets of electrodes may even make intermittent contact, resulting in short circuits and potential fires. The traditional solution is to measure the height difference at the installation site and adjust the anchor bolts to compensate for this difference. This method requires on-site installation and debugging by after-sales service personnel, increasing labor costs. Summary of the Invention

Detailed Implementation

[0033] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0034] like Figure 1 As shown, the present invention provides an automatically adjustable charging structure, including a robot body charging structure A and a charging station charging structure B. The robot body charging structure A includes two body charging electrodes 1 and a body adjustment groove 2 disposed between the two body charging electrodes 1. The charging station charging structure B includes an electrode mounting frame 6 and an adjustment mechanism, a gear transmission mechanism, and two charging station electrodes 3 disposed on the electrode mounting frame 6. The gear transmission mechanism is disposed within the electrode mounting frame 6, and the two charging station electrodes 3 are disposed on the front side of the electrode mounting frame 6 and are both connected to the gear transmission mechanism. The adjustment mechanism is disposed between the two charging station electrodes 3 and can slide in the front-back direction. The adjustment mechanism is used to dock with the body adjustment groove 2 and drive the two charging station electrodes 3 to swing synchronously through the gear transmission mechanism, so as to realize the docking of the two charging station electrodes 3 with the two body charging electrodes 1 respectively.

[0035] like Figure 2-3 As shown in the embodiment of the present invention, the gear transmission mechanism includes a positioning gear I7, a positioning gear II8, a positioning gear shaft II9, and a positioning gear shaft I10. The positioning gear II8 is mounted within the electrode mounting bracket 6 via the positioning gear shaft II9. There are two positioning gears I7, each mounted within the electrode mounting bracket 6 via two positioning gear shafts I10. The positioning gear shafts II9 and I10 are parallel to each other, and both positioning gears I7 mesh with the positioning gear II8. The two charging station electrodes 3 are connected to the positioning gear shafts I10 and II9 respectively, and can rotate with the positioning gear shafts I10 and II9.

[0036] Furthermore, two gear blocks 12 are provided on the adjusting gear II8; the adjusting mechanism can drive the adjusting gear II8 to rotate in the forward or reverse direction through the two gear blocks 12 respectively.

[0037] Based on the above embodiments, the gear transmission mechanism also includes a gear balance adjustment mechanism, which is used to adjust the gear II8 to always be in a balanced state.

[0038] like Figure 3 As shown in the embodiment of the present invention, the gear balancing adjustment mechanism includes a connecting rod and two tension springs 11. The connecting rod is perpendicularly connected to the adjusting gear shaft II 9, and the two tension springs 11 are respectively connected to both ends of the connecting rod. The lower ends of the two tension springs 11 are connected to the electrode mounting bracket 6. The two tension springs 11 keep the adjusting gear II 8 in its initial balanced state.

[0039] Specifically, a gear balancing mechanism is provided on each side of the adjusting gear II8.

[0040] The working principle of the gear transmission mechanism in this invention is as follows:

[0041] like Figure 2-3 As shown, adjusting gear I7 and adjusting gear II8 are fixed to the middle positions of adjusting gear shaft I10 and adjusting gear shaft II9 respectively by snap rings. Adjusting gear shaft I10 and adjusting gear shaft II9 are fixed to the electrode mounting bracket 6 by oilless sleeves, allowing for smooth rotation. The adjusting gears mesh with each other, and the two charging station electrodes 3 are fixed to adjusting gear shaft I10 and adjusting gear shaft II9 respectively. When the adjusting gears rotate, the charging station electrodes 3 will also rotate accordingly. Four tension springs 11 hold the adjusting gear shaft II9, ensuring that the adjusting gear shaft II9 is ​​in a balanced position when no external force is applied.

[0042] like Figure 4 As shown, in an embodiment of the present invention, the adjustment mechanism includes an upper adjustment block 4, a lower adjustment block 5, an upper adjustment block slide shaft 13, a lower adjustment block slide shaft 14, an upper adjustment connection assembly, and a lower adjustment connection assembly. The upper and lower adjustment block slide shafts 13 and 14 are slidably connected to the electrode mounting bracket 6, and are perpendicular to the adjustment gear shaft I 10 and adjustment gear shaft II 9. The upper and lower adjustment blocks 4 and 5 are respectively disposed at the front ends of the upper and lower adjustment block slide shafts 13 and 14, respectively, and the upper and lower adjustment connection assemblies are respectively disposed at the rear ends of the upper and lower adjustment block slide shafts 13 and 14.

[0043] In an embodiment of the present invention, the upper and lower sides of the body adjustment groove 2 are respectively provided with a travel curved surface 2-01; the upper part of the upper adjustment block 4 is provided with an upper curved surface 4-01, which is adapted to the travel curved surface 2-01 on the upper part of the body adjustment groove 2; the lower part of the lower adjustment block 5 is provided with a lower curved surface 5-01, which is adapted to the travel curved surface 2-01 on the lower part of the body adjustment groove 2.

[0044] In embodiments of the present invention, the upper-position adjustment connection assembly includes an upper-position adjustment connector 18 and an upward push post 18-01 disposed on the upper-position adjustment connector 18, the upward push post 18-01 corresponding to the gear stop 12 located above the adjustment gear II 8; the lower-position adjustment connection assembly includes a lower-position adjustment connector 19 and a downward push post 19-01 disposed on the lower-position adjustment connector 19, the downward push post 19-01 corresponding to the gear stop 12 located below the adjustment gear II 8. Therefore, the stroke surface 2-01 is calculated from the running trajectory after the upper-position adjustment block 4 and the lower-position adjustment block 5 are triggered.

[0045] Furthermore, the upper position adjustment block slide shaft 13 and the lower position adjustment block slide shaft 14 are respectively provided with an upper guide boss 13-01 and a lower guide boss 14-01, which are slidably engaged with the corresponding guide grooves 6-01 on the electrode mounting bracket 6.

[0046] Furthermore, the upper adjustment block slide 13 and the lower adjustment block slide 14 are connected to the electrode mounting bracket 6 via a baffle 17. Two compression springs 16 are respectively fitted on the upper adjustment block slide 13 and the lower adjustment block slide 14. One end of the compression spring 16 abuts against the baffle 17, and the other end abuts against the retaining rings 15 provided on the upper adjustment block slide 13 and the lower adjustment block slide 14. The compression springs 16 provide a restoring force after the upper adjustment block slide 13 and the lower adjustment block slide 14 are compressed.

[0047] like Figure 5 As shown, when the robot is charging, when the main body charging electrode 1 is connected to the charging station electrode 3, and the main body charging electrode 1 is higher than the charging station electrode 3, the main body adjustment groove 2 will first hit the lower adjustment block 5 and push the lower adjustment block slide shaft 14 to move backward. Then, the push column 19-01 on the lower adjustment connector 19 pushes the gear stop block 12 on the lower side of the adjustment gear II8. At this time, the adjustment gear II8 will rotate counterclockwise around the axis of the adjustment gear shaft II9, driving the two adjustment gears I7 to rotate clockwise. At the same time, the two charging station electrodes 3 rotate clockwise until the main body charging electrode 1 contacts it and stops.

[0048] like Figure 6As shown, when the robot is charging, the main body charging electrode 1 needs to be connected with the charging station electrode 3. When the main body charging electrode 1 is lower than the charging station electrode 3, the main body adjustment groove 2 will first hit the upper adjustment block 4 and push the upper adjustment block sliding shaft 13 to move backward. Then, the push column 18-01 on the upper adjustment connector 18 pushes the gear stop block 12 on the upper side of the adjustment gear II 8. At this time, the adjustment gear II 8 will rotate clockwise around the axis of the adjustment gear rotating shaft II 9, driving the two adjustment gears I 7 to rotate counterclockwise. At the same time, the two charging station electrodes 3 rotate counterclockwise until the main body charging electrode 1 contacts it and stops.

[0049] This invention can automatically adjust the height of the charging electrodes, ensuring full charging and preventing short circuits and open circuits. This guarantees the reliability and stability of charging when the robot is working on uneven ground. This automatic adjustment mechanical structure allows for accurate and efficient docking of the robot's charging electrodes, greatly improving charging efficiency and success rate.

[0050] The above description is merely an embodiment of the present invention and is not intended to limit the scope of protection of the present invention. Any modifications, equivalent substitutions, improvements, extensions, etc., made within the spirit and principles of the present invention are included within the scope of protection of the present invention.
