DETAILED DESCRIPTION
[0024] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present application more clear, explicit, the present application will be further described in detail in combination with the drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application, and are not used to limit the present application.
[0025] The present embodiment discloses a robot, which comprises a handrail. It is worth mentioning that the robot in the present embodiment can be a cleaning robot, or other robots that need to be installed with a handrail. As shown in the figure, Figure 1 The handrail comprises a handrail rod 1, two unlocking pieces 2 and two spaced connecting pieces 3, the connecting pieces 3 are used to install the handrail on the robot, and the two connecting pieces 3 are generally respectively installed on both sides. The handrail rod 1 is generally U-shaped or C-shaped, of course, it can also be other shapes. The handrail rod 1 comprises two connecting ends 11 respectively located at both ends, the two connecting ends 11 are respectively rotationally connected with the two connecting pieces 3, the two unlocking pieces 2 respectively correspond to the two connecting ends 11 and the two connecting pieces 3, the unlocking piece 2 is inserted into the corresponding connecting piece 3 after passing through the corresponding connecting end 11, and the two unlocking pieces 2 are both movable relative to the corresponding connecting piece 3. As shown in the figure, Figure 2 The two unlocking pieces 2 are both provided with a lock block 221, in combination with Figure 3 and Figure 4As shown, the two connecting ends 11 are each provided with a locking groove 111. When the handrail is needed to be used, the handrail rod 1 is turned upward to open, and when the handrail rod 1 is turned to be fully opened, the locking block 221 is aligned with the locking groove 111, the unlocking piece 2 moves away from the connecting piece 3 to make the locking block 221 inserted into the locking groove 111, so that the handrail rod 1 is locked, and in the subsequent process of moving the robot by pushing the handrail rod 1, the handrail rod 1 cannot be turned up and down again due to the locking, which effectively avoids the shaking in the use process, and makes the use more convenient. When the handrail is needed to be folded after use, the unlocking piece 2 is pressed, the unlocking piece 2 moves close to the connecting piece 3 to make the locking block 221 disengaged from the locking groove 111 to be unlocked, and then the handrail rod 1 can be turned downward to be reset.
[0026] In the embodiment, as shown in Figure 1 , the handrail further comprises two reset springs 4, and the two reset springs 4 are respectively arranged corresponding to the two unlocking pieces 2. In combination with Figures 1-4 , when the unlocking piece 2 moves close to the connecting piece 3, the reset spring 4 is elastically deformed; the elastic force generated by the elastic deformation of the reset spring 4 is used to drive the unlocking piece 2 to move away from the connecting piece 3, so that the locking block 221 is inserted into the locking groove 111 to be locked. When the handrail rod 1 is not fully turned upward to be opened, the reset spring 4 is in the elastic deformation state; when the handrail rod 1 is turned upward to be fully opened, the locking block 221 is aligned with the locking groove 111, the reset spring 4 drives the unlocking piece 2 to automatically move away from the connecting piece 3, the locking block 221 is inserted into the locking groove 111 to be locked, and the reset spring 4 is arranged to realize the automatic locking; when the handrail is needed to be folded after use, the unlocking piece 2 is pressed, the unlocking piece 2 moves close to the connecting piece 3, the locking block 221 is disengaged from the locking groove 111, the reset spring 4 is elastically deformed, and after the handrail rod 1 is turned downward, the locking block 221 is misaligned with the locking groove 111, and the connecting end 11 abuts against the locking block 221 to make the unlocking piece 2 unable to move away from the connecting piece 3.
[0027] In the embodiment, in combination with Figure 1 and Figure 2 , the unlocking piece 2 comprises a button part 21 and a limiting rod 22, the limiting rod 22 is installed on the button part 21, the locking block 221 is arranged on the limiting rod 22, the button part 21 is movably inserted on the outside of the handrail rod 1, and the limiting rod 22 passes through the connecting end 11 of the handrail rod 1 and is inserted on the connecting piece 3. It is worth mentioning that in the present application, the outside refers to the side relatively away from the connecting piece 3, and the inside refers to the side relatively close to the connecting piece 3. In the embodiment, the limiting rod 22 of the two unlocking pieces 2 is each provided with a limiting block 222, in combination with Figure 3 and Figure 4As shown, the two connecting ends 11 of the handrail rod 1 are each provided with a limiting piece 112, and the limiting rod 22 of the two unlocking members 2 is provided with a gap 223 and an avoiding space 224 in communication with the gap 223 beside the limiting block 222. When the handrail rod 1 is in the open state, the limiting block 222 and the limiting piece 112 are aligned along the axial direction of the limiting rod 22; when it is needed to fold the handrail rod 1 from the open state, the button part 21 of the unlocking member 2 is pressed, the unlocking member 2 moves close to the connecting member 3, the locking block 221 is separated from the locking groove 111, the limiting block 222 moves close to the connecting member 3, the limiting piece 112 passes the limiting block 222, the limiting block 222 moves from the outside of the limiting piece 112 to the inside of the limiting piece 112, and the limiting piece 112 clamps the unlocking member 2 due to the mutual limiting action between the limiting block 222 and the limiting piece 112. At this time, even if the locking block 221 and the locking groove 111 are still aligned, the elastic force of the reset spring 4 cannot drive the unlocking member 2 to move away from the connecting member 3, and the hands of a person can be away from the unlocking member 2. After the handrail rod 1 is subsequently rotated downward to the reset state, the limiting block 222 and the limiting piece 112 are disengaged, the elastic force of the reset spring 4 drives the unlocking member 2 to move away from the connecting member 3 by a small distance, so that the limiting piece 112 passes the gap 223 from the outside of the limiting block 222 to the inside of the limiting block 222; in the process of rotating from the reset state to the fully open state, the limiting piece 112 rotates relative to the avoiding space 224. When the limiting piece 112 and the limiting block 222 are not provided, the pressing of the unlocking member 2 and the downward rotation of the handrail rod 1 must be performed synchronously, otherwise the unlocking member 2 will be reset under the driving of the reset spring 4; after the limiting piece 112 and the limiting block 222 are provided, the pressing of the unlocking member 2 and the downward rotation of the handrail rod 1 are split into two independent actions, the unlocking member 2 cannot be reset after being pressed once due to the clamping of the limiting piece 112 to the unlocking member 2, the hands of a person can be away from the unlocking member 2 after being pressed once, and even after a period of time, the handrail rod 1 can still be freely rotated without needing to press the unlocking member 2 all the time or pressing the unlocking member 2 again. In the embodiment, the limiting block 222 is provided with an auxiliary inclined surface 2221, and the auxiliary inclined surface 2221 is arranged to facilitate the limiting piece 112 to pass the limiting block 222 so that the limiting piece 112 moves from the inside of the limiting block 222 to the outside of the limiting block 222.
[0028] In the embodiment, as shown in FIG. 1, Figure 1As shown, the handrail further comprises two rotating discs 5, which are respectively installed with the two connecting ends 11 of the handrail rod 1, and the rotating discs 5 and the connecting ends 11 are respectively located at two sides of the connecting piece 3, and the rotating discs 5 and the button part 21 of the unlocking piece 2 are respectively located at two sides of the connecting ends 11. When the handrail rod 1 rotates, the rotating discs 5 rotate with the handrail rod 1, and the rotating discs 5 and the connecting ends 11 are matched to realize the rotating connection of the connecting ends 11 to the connecting piece 3. In the embodiment, the handrail rod 1 is provided with two limiting grooves 12 which are arranged at intervals, and the limiting grooves 12 are used for limiting with the additional limiting piece to limit the upward rotation of the handrail rod 1. After the handrail rod 1 is returned to the original position, the limiting grooves 12 are matched with the additional limiting piece to avoid the upward rotation of the handrail rod 1. In the embodiment, the handrail rod 1 is provided with two handrail handles 13 which are arranged at intervals, and the handrail handles 13 are used for pushing the handrail to drive the robot to move. The shape of the handrail handles 13 is preferably cylindrical or prismatic, and the edges of the prismatic shape are generally rounded to facilitate better holding.
[0029] The handrail rod 1 in the embodiment has an open state and a return state, and in the use process: when the handrail needs to be used, generally from the return state to the open state, the handrail rod 1 is rotated upward to the open state, the lock block 221 is aligned with the lock groove 111, the elastic force of the return spring 4 drives the unlocking piece 2 to move away from the connecting piece 3, the lock block 221 is inserted into the lock groove 111 to realize the locking of the handrail rod 1; when the handrail needs to be folded after use, generally from the open state to the return state, the unlocking piece 2 is pressed, the unlocking piece 2 moves close to the connecting piece 3, the lock block 221 is separated from the lock groove 111, the limiting piece 112 passes through the limiting block 222, the limiting block 222 moves from the outside of the limiting piece 112 to the inside of the limiting piece 112, and the handrail rod 1 is rotated downward to the return state to be folded.
