Abstract
Description
Technical Field
[0001] The utility model belongs to the field of sweeping robots, and in particular relates to a sweeping robot which is easy to move manually. Background Art
[0002] The original intention of designing a sweeping robot is to automate the cleaning process and reduce manual labor. Most of the time, the sweeping robot is installed in a certain place and moves autonomously according to the preset route to complete the cleaning task without manual movement. But sometimes, for example, when the cleaning location needs to be changed or the robot suddenly encounters an obstacle and cannot move autonomously, the sweeping robot needs to be moved manually. However, due to the following reasons, the current sweeping robots are not easy to move manually:
[0003] Weight and size: Robot vacuums are often designed to be heavy to maintain stability and suction power, which makes it cumbersome and laborious to drag them manually.
[0004] Wheel design: The wheels of a sweeping robot are usually designed to roll on different surfaces rather than to be dragged. The wheels are active wheels and are constrained by driving components such as motors. Manual dragging may damage the wheels or affect the robot's mobility. Utility Model Content
[0005] The utility model aims to provide a sweeping robot that is easy to move manually, so that when the sweeping robot cannot move autonomously due to obstacles or needs to switch the cleaning place, the sweeping robot can be moved manually.
[0006] The utility model is implemented as follows: a sweeping robot that is easy to move manually comprises a chassis, a driving mechanism and a driving wheel are installed on the chassis, the driving wheel is in transmission connection with the driving mechanism, and the driving mechanism is used to drive the driving wheel to rotate so as to drive the chassis to move; the sweeping robot also comprises a handle and a driven wheel, the handle is fixedly installed at one end of the chassis, and the driven wheel is rotatably installed at the bottom of the other end of the chassis; when the end of the chassis where the handle is installed is tilted upward, the driving wheel is suspended in the air, and the driven wheel is in contact with the ground.
[0007] Furthermore, the handle is mounted on the chassis via a telescopic structure. When the telescopic structure is extended, the handle protrudes out of the outer edge of the chassis. When the telescopic structure is retracted, the handle is stored on the top surface of the chassis.
[0008] Furthermore, the telescopic structure includes a telescopic rod fixing seat and a telescopic rod assembly, wherein the telescopic rod assembly includes at least two sections of telescopic rods nested inside and outside, the telescopic rod fixing seat is fixed on the top surface of the chassis, the outer periphery of the telescopic rod located in the outermost circle is fixedly connected to the telescopic rod fixing seat, and the end of the telescopic rod located in the innermost circle is fixedly connected to the handle.
[0009] Furthermore, the sweeping robot has two groups of telescopic rod assemblies, and the two groups of telescopic rod assemblies are respectively fixed at two ends of the handle.
[0010] Furthermore, the sweeping robot also includes an upper shell covering the chassis, and a clearance opening for the handle to enter and exit is reserved on the upper shell at a position corresponding to the handle. When the telescopic structure is retracted, the handle is hidden inside the upper shell.
[0011] Furthermore, the handle is mounted on the chassis via a rotating structure, and the handle can be swung relative to the chassis via the rotating mechanism. By swinging the handle at different angles, the handle can be swung to the outer edge of the chassis, or the handle can be stored on the top surface of the chassis.

[0021] Embodiment 1:
[0022] This embodiment provides a sweeping robot that is easy to move manually. Figure 1 The sweeping robot comprises a chassis 1, a driving mechanism, a driving wheel 2, a driven wheel 3 and a handle 4. The driving mechanism and the driving wheel 2 are mounted on the chassis 1. The driving wheel 2 is in transmission connection with the driving mechanism. The driving mechanism is used to drive the driving wheel 2 to rotate so as to drive the chassis 1 to move. The handle 4 is fixedly mounted at one end of the chassis 1, and the driven wheel 3 is rotatably mounted at the bottom of the other end of the chassis 1; Figure 2 As shown, when the end of the chassis 1 where the handle 4 is installed is tilted upward, the driving wheel 2 is suspended in the air and the driven wheel 3 is in contact with the ground.
[0023] By adopting the structural design in which the handle 4 and the driven wheel 3 are respectively installed at the two ends of the chassis 1, the user can tilt the sweeping robot by grasping the handle 4. At this time, the driving wheel 2 is suspended in the air and the driven wheel 3 is in contact with the ground. The user can drag the sweeping robot to move, and since the driving wheel 2 is not in contact with the ground, it will not affect the driving wheel 2.
[0024] Specifically, the sweeping robot of this embodiment further includes an upper shell 5 and a telescopic structure, and the upper shell 5 covers the chassis 1. Figure 3 A clearance opening 51 for the handle to enter and exit is reserved on the upper shell 5 at a position corresponding to the handle 4. Figure 4 The telescopic structure includes a telescopic rod fixing seat 6 and a telescopic rod assembly 7. The telescopic rod assembly includes at least two sections of telescopic rods nested inside and outside. The telescopic rod fixing seat 6 is fixed on the top surface of the chassis 1. The outer periphery of the telescopic rod located in the outermost circle is fixedly connected to the telescopic rod fixing seat 6, and the end of the telescopic rod located in the innermost circle is fixedly connected to the handle 4. Preferably, this embodiment has two sets of telescopic rod assemblies 7, which are respectively fixed at both ends of the handle 4 to form a U shape together.
[0025] When the user holds the handle 4 and stretches the telescopic rod assembly, the handle 4 protrudes out of the outer side of the chassis 1. At this time, the sweeping robot can be tilted and dragged. After the sweeping robot moves to the target position, it is lowered to a horizontal state. At this time, the user can compress the telescopic rod assembly 7 and hide the telescopic rod assembly 7 together with the handle 4 inside the upper shell 5 to prevent the handle from interfering with surrounding objects when the sweeping robot is working normally, and to prevent the handle from being exposed and affecting the aesthetic appearance of the sweeping robot.
[0026] Embodiment 2:
[0027] This embodiment provides another sweeping robot that is easy to move manually. The general structure of the sweeping robot is the same as that of the first embodiment, except that this embodiment uses a rotating structure to replace the telescopic structure in the first embodiment.
[0028] The handle is mounted on the chassis via a rotating structure, and the handle can be swung relative to the chassis via the rotating mechanism. By swinging the handle at different angles, the handle can be swung to the outer side of the chassis, or the handle can be stored on the top surface of the chassis.
[0029] Specifically, the rotating mechanism of this embodiment includes a swing rod, a connecting shaft and an articulated seat, the articulated seat is fixed on the chassis, one end of the swing rod is hinged to the articulated seat through the connecting shaft, the other end of the swing rod is a free end, and the handle is fixed on the free end of the swing rod.
[0030] When the user holds the handle and pulls out the swing rod, the handle can rotate relative to the chassis and extend out of the chassis. At this time, the sweeping robot can be tilted and dragged. When the sweeping robot moves to the target position, the sweeping robot is lowered to a horizontal state. At this time, the user can push the swing rod inward to make the swing rod and the handle swing together and hide inside the upper shell to prevent the handle from interfering with surrounding objects when the sweeping robot is working normally, and to prevent the handle from being exposed and affecting the appearance of the sweeping robot.
[0031] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
