The drive control box integrates a drive control board and a motion conversion module, the motion conversion module converts linear motion of a motor into linear motion of a rope, each sub-module of the motion conversion module is in a modular design, and positions for installing other measuring elements in the future are reserved.
Details of the charger robot elevator 300 and the terminal charging device 100 according to the present invention will be described in detail below with reference to fig. 2 to 4 in some embodiments.
Referring to fig. 2, the lifter 300 includes a primary base 301, a primary rack 302, a primary gear 303, a secondary base 304, a secondary rack 305, a secondary gear 306, a secondary guide 307, a flexible arm fixing base 308, a lifting motor 309, and a primary guide 310. Wherein, one-level base 301 and one-level rack 302 link firmly, and one-level base 301 and one-level guide rail 310 link firmly, and elevator motor 309 sets up in the inner chamber of second grade base 304 and links firmly with second grade base 304, and flexible arm fixing base 308 and second grade rack 305 link firmly. The above-mentioned guide rail and rack are arranged parallel to each other in the vertical direction.
With continued reference to fig. 2, the primary base 301 may be fixed to a wall within the receiving space and arranged vertically. The secondary base 304 is an elongated structure in the vertical direction and has an inner cavity, and the secondary base 304 may be fixed at the bottom with a slide block on the primary guide rail 310, so as to realize a sliding fit with the guide rail, so as to allow the secondary base 304 to move linearly in the vertical direction. The flexible arm mount 308 has a support plane that is perpendicular to the vertical direction and is fixed to the bottom of the cable driven flexible arm 200. The flexible arm holder 308 may be fixed to a slide block on the secondary guide rail 307, so as to achieve a sliding fit with the guide rail, so as to allow the flexible arm holder 308 to move linearly in the vertical direction.
The primary gear 303 and the secondary gear 306 are both mounted on the same side of the secondary base 304. Preferably, the primary gear 303 is near the bottom edge of the elongated secondary base 304 and the secondary gear 306 is near the top edge of the elongated secondary base 304 to achieve as much lift travel as possible with the elongated structure of the secondary base 304. The toothed portions of the primary rack 302 and said secondary rack 305, which are parallel to each other, face each other. The primary rack 302 meshes with the primary gear 303, and the secondary rack 305 meshes with the secondary gear 306. The distance between the primary rack 302 and the secondary rack 305 is larger (generally slightly larger) than the diameters of the primary gear 303 and the secondary gear 306, so that the interference between the gear of one stage and the racks of other stages is avoided.
The lifting motor 309 can directly drive the primary gear 303 to rotate. In the inner cavity of the secondary base 304, the output shaft of the lifting motor 309 can be coaxially connected with a primary synchronous pulley in a multiple connection manner, the secondary rack 305 is also coaxially connected with a secondary synchronous pulley, wherein two synchronous pulleys are driven by a synchronous belt, and therefore the primary gear 303 can drive the secondary gear 306 to rotate together. In a work project, the lifting motor 309 is electrified to drive the first-stage gear 303 to rotate, the first-stage gear 303 rotates to drive the second-stage gear 306 to rotate through the synchronous belt wheel, after the first-stage gear 303 rotates, the first-stage rack 302 is fixed on the first-stage base 301 and cannot move, so that the reaction force of the first-stage gear 303 drives the second-stage base 304 to move, the second-stage gear 306 rotates to drive the second-stage rack 305 to do translational motion, the second-stage rack 305 drives the flexible arm fixing seat 308 to do translational motion, and thus the lifting motor 309 realizes two-stage lifting travel.
The top of the secondary base 304 is provided with a cover plate so that when the lift 300 lowers the cable driven flexible arm 200 to the fully stowed position, the cover plate is level with the ground. When the lifter 300 raises the cord-driven flexible arm 200 to the extended position, an open window is provided between the peripheral wall of the receiving space and the cover plate to allow the cord-driven flexible arm 200 to extend from the open window. This can achieve the function of installing the robot below the ground but charging above the ground.
Referring to fig. 3, to prevent the reverse of the elevator 300, the elevator 300 of the present invention preferably includes a wedge self-locking mechanism. The self-locking mechanism comprises a rope retraction motor 311, a wedge rope 312, a first wedge surface 313 (a first-stage base wedge surface) 313, a friction wedge 314 and a second wedge surface 315 (a second-stage base wedge surface) 315. Wherein the contact surfaces of first wedge surface 313, second wedge surface 315, friction wedge 314 and associated components are all treated with a glue surface. The first wedge surface 313 and the second wedge surface 315 form an acute angle, preferably an acute angle of not more than 45 degrees.
In this embodiment, in a specific self-locking operation process, the rope retracting motor 311 loosens the wedge rope 312, so that the friction wedge 314 is in a contact state with both the second wedge surface 315 and the first wedge surface 313 due to the action of gravity, the lifting motor 309 moves, the secondary base 304 moves upward along the primary guide rail 310 relative to the primary base 301, after the lifting motor 309 stops, the secondary base 304 has a tendency to move downward along the primary guide rail 310 relative to the primary base 301 due to the gravity of the flexible robot, but the secondary base 304 and the primary base 301 cannot slide relatively due to the action of the friction wedge 314, which plays a self-locking role. When the elevator 300 needs to perform a descending motion, the rope retraction motor 311 pulls the wedge rope 312, so that the friction wedge 314, the second wedge surface 315, and the first wedge surface 313 are all in a disengaged state, thereby releasing the self-locking of the mechanism and enabling the base of the elevator 300 to descend smoothly.
Referring to fig. 4, in one embodiment, the terminal charging device 100 includes a charging head 101, a pressure sensor 102, a camera 103, and a terminal charging device motor 104. When the terminal charging device motor 104 drives the charging head 101 to charge through the intermediate transmission element, the pressure sensor 102 detects the pressure applied to the charging head 101 in real time, and the camera 103 is used for detecting a target position and detecting a charging process. Specifically, the end charging device motor 104 implements two motions of the charging hand grip of the end charging device 100 through a lead screw nut spring mechanism, the first motion being a linear motion of the charging hand grip, and the second motion being an arc motion of the charging hand grip. The terminal charging device 100 is further integrated with a pressure sensor 102 and a camera 103, the pressure sensor 102 can detect the pressure between the terminal charging device 100 and a charging port in the charging process in real time, and the camera 103 can judge the position and the posture of the charging port through image recognition and feed back information to a central controller in real time to provide feedback information for the motion control of the robot.
Fig. 5 is a diagram of a charging interface, and main geometric features of the charging interface comprise a straight line feature 105, a circular feature 106 and a circular arc feature 107. In a specific single-camera recognition process, when the robot is just sent out of the ground by the elevator 300, the tail end of the mechanical arm drives the camera 103 to scan the whole space according to a set track, and when a charging port characteristic target is recognized, the robot stops, and then specific position and posture measurement recognition is carried out. In the scanning identification process, the camera 103 shoots images at the rate of 20 frames per minute, the circular arc feature 107 and the circular feature 106 in the images are extracted and compared with the circular arc feature 107 and the circular feature 106 of the charging head 101 pre-existing in the robot control system, and when the features are overlapped, the position of the charging port is scanned. In the process of measuring and identifying the position and the posture, after the camera 103 scans the approximate position of the charging port, the length information of a linear feature 105 of the charging port, the size pointing information of a circular feature 106 and the pointing information of an arc feature 107 in an image are extracted; then, image calculation is carried out on the information and the relevant information of the charging port which is already stored locally, so that the position and the posture information of the charging port can be obtained. The rest of the processing engineering also needs filtering, image enhancement, space coordinate transformation and the like.
