Description
Docking station, mobile robot and device including same
[0001] The present invention relates to a docking station, a mobile robot, and a device including the same for removing internal dust of a mobile robot while the mobile robot is docked to the docking station.
[0002] Robots have been developed for industrial use to fulfill a portion of factory automation. Recently, the scope of robotics applications has expanded, with developments not only of medical and aerospace robots but also of robots for everyday use.
[0003] Among industrial robots, robots that perform precise assembly work have been developed for automation because they perform the same movements repeatedly and repeat the same movements in a fixed location without any unexpected situations.
[0004] However, the transportation sector, including driving, which requires the ability to assess emergencies, has not yet seen widespread commercialization of robots. However, with the recent advancements in sensors capable of perceiving the surroundings and the advancements in computer power capable of quickly processing and responding to perceived information, the number of autonomous robots is increasing.
[0005] Industrially, robots that perform transportation functions are attracting attention, and competition is intensifying. In addition to robots that transport large or bulky items, there is a growing demand for robots that transport smaller items to their destinations.
[0006] Meanwhile, the robot contains a control box housing various electronic components, including a main board. Typically, the control box is equipped with a blower to cool the internal space against the heat generated by the various electronic components. A convection method is used to cool the internal space of the control box through the blower.
[0007] However, the aforementioned blower-based cooling method forces a large amount of air into the system from the outside. Therefore, in logistics environments where robots are heavily used, a significant amount of dust inevitably enters the robot's interior. Accumulation of dust inside the robot can ultimately lead to short circuits in electronic components. This can lead to errors in the robot's operation and even lead to robot damage.
[0008] Therefore, a means for efficiently removing dust is required to prevent dust from accumulating inside the robot.
[0009] The present invention provides a docking station, a mobile robot, and a device including the same, and more specifically, a docking station, a mobile robot, and a device including the same, which can remove internal dust of a mobile robot by sucking air through a dust collecting motor of the docking station in a state where a dust collecting pipe of the docking station and an air collecting pipe of the mobile robot are connected.

A plurality of proximity sensors (141) may be provided along the perimeter of the mobile robot (100), and may also be provided on the upper side of the mobile robot (100) to detect obstacles above.
[0079] Lidar (142) is a device that precisely maps its surroundings by emitting laser pulses and receiving the light reflected from surrounding objects. While similar in principle to radar, it utilizes different electromagnetic waves, resulting in different technologies and applications.
[0080] Lasers can damage human eyesight because they use light with a wavelength of 600 to 1000 nm. Lidar (142) uses a longer wavelength and is used to measure not only the distance to a target object, but also its speed and direction, temperature, and the analysis and concentration of surrounding atmospheric substances.

[0101] FIG. 4 is a drawing illustrating a docking station (600) and a body (101) of a mobile robot (100) according to one embodiment of the present invention. FIG. 5 is a drawing illustrating the interior of a body (101) of a mobile robot (100) according to one embodiment of the present invention. FIG. 6 is a drawing illustrating an air flow pipe (130) of a mobile robot (100) according to one embodiment of the present invention. FIG. 7 is a cross-sectional view of a docking station (600) and a mobile robot (100) before docking according to one embodiment of the present invention. And FIG. 8 is a cross-sectional view of a docking station (600) and a mobile robot (100) according to one embodiment of the present invention in a docked state.
[0102] Hereinafter, in describing a docking station (600), a mobile robot (100), and a device (100, 600) including the same according to one embodiment of the present invention, the forward and backward directions will be described based on the x-axis direction, the left and right directions will be described based on the y-axis direction, and the up and down directions will be described based on the z-axis direction.
[0103] First, the mobile robot (100) according to one embodiment of the present invention can move through a driving unit (170) located at the lower part of the body (101), as described above with reference to FIG. 2. In addition, the body (101) of the mobile robot (100) may have a box-shaped shape.
[0104] Referring to FIG. 2, the main wheel (171) constituting the driving unit (170) is connected to a motor to directly transmit driving force to the body (101), and the speed of the motor can be adjusted to control the moving speed of the mobile robot (100).
[0105] And the caster (172) may include an axle, which is the rotation axis of the wheel, and a main shaft that is arranged perpendicular to the axle and rotates with respect to the body (101). The direction of movement of the mobile robot (100) can be controlled by using the caster (172), or the direction of travel can be changed by adjusting the left and right rotation speed of the main wheel (171). The body (101) can also rotate in place by adjusting the direction of the caster (172), and this type of driving unit (170) can play a role in helping the mobile robot (100) avoid obstacles and move in a limited space.
[0106] A control box (102) in which electronic components are mounted may be located inside the body (101) of the mobile robot (100). A plurality of holes may be formed on the front of the control box (102). In addition, at least one blower (107) may be located on the front of the control box (102).
[0107] Here, at least one blower (107) positioned on the front of the control box (102) can serve to cool the internal space of the control box (102) to counteract heat generation of electronic components mounted on the control box (102). That is, the blower (107) can counteract heat generation of electronic components by blowing air into the internal space of the control box (102) through a plurality of holes formed on the front of the control box (102).
[0108] However, as described above, convection cooling using a blower (107) causes a large amount of air to flow in from the outside. In particular, in the case of a logistics site where a mobile robot (100) according to an embodiment of the present invention is frequently used, a large amount of dust is bound to flow into the interior of the mobile robot (100) due to the nature of the working environment.
[0109] In this case, if dust that has entered the interior of the mobile robot (100) accumulates inside the control box (102), a short circuit may eventually occur in the electronic components. This may cause errors in the operation of the mobile robot (100) and further result in damage to the mobile robot (100).
[0110] Accordingly, the purpose of a mobile robot (100) according to one embodiment of the present invention is to discharge internal dust of the mobile robot (100) while docked to a docking station (600).
[0111] To this end, the mobile robot (100) according to one embodiment of the present invention may include an air passage pipe (130) positioned between the front of the body (101) and the front of the control box (102) and capable of moving in the forward and backward direction (x-axis direction). Here, when one end of the air passage pipe (130) is coupled with a dust collection pipe (620) positioned at the front of the docking station (600), the air passage pipe (130) may move backward so that the other end may be brought into close contact with the front of the control box (102). More specific details for discharging internal dust of the mobile robot (100) will be described later.
[0112] In addition, a docking station (600) according to one embodiment of the present invention can collect internal dust of a mobile robot (100) while the mobile robot (100) is docked. The docking station (600) can include a housing (610), a dust collection pipe (620), a dust collection motor (630), and a dust collection filter (640).
[0113] The dust collection pipe (620) is formed on the front of the housing (610) and can be combined with the air flow pipe (130) located in the mobile robot (100). In addition, the dust collection motor (630) is located inside the housing (610) and can serve to suck in the internal air of the mobile robot (100) through the air flow pipe (130) and the dust collection pipe (620). In addition, the dust collection filter (640) can surround the dust collection motor (630) and collect dust in the sucked air.
[0114] In addition, the docking station (600) according to one embodiment of the present invention may include an exhaust port (650) formed on the upper surface of the housing (610) and through which air from which dust has been removed is discharged through a dust collecting filter (640). In addition, the dust collecting motor (630) may discharge air from which dust has been removed through the exhaust port (650).
[0115] Here, the dust collection filter (640) may include a High Efficiency Particulate Air (HEPA) filter containing activated carbon. The HEPA filter can increase dust collection efficiency, and as described above, air from which dust has been removed by passing through the HEPA filter can be discharged to the outside. Therefore, the docking station (600), the mobile robot (100), and the device (100, 600) including the same according to one embodiment of the present invention can also achieve an air purifying effect.
[0116] And, a docking station (600) according to one embodiment of the present invention may include a charging port (660) formed on the front of the housing (610) and coupled with a charging terminal (108) formed on the front of the mobile robot (100).
[0117] That is, according to one embodiment of the present invention, the docking station (600), the mobile robot (100), and the device (100, 600) including the same can allow the mobile robot (100) to be docked to the docking station (600) for charging, and at the same time, discharge internal dust of the mobile robot (100). Therefore, since there is no need to install a separate device for removing internal dust of the mobile robot (100), there is an advantage in that the efficiency of space utilization can be increased and additional cost consumption can be reduced.
[0118] In addition, a docking station (600) according to one embodiment of the present invention may include a restraining plate (670) formed at the lower portion of the housing (610) and preventing movement of the mobile robot (100) when the charging terminal (108) and the charging port (660) are coupled. Referring also to FIG. 4, the restraining plate (670) may have a rim shape with a groove formed in the center.
[0119] More specifically, referring to FIG. 4, FIG. 7 and FIG. 8 together, the restraint plate (670) can serve to increase the stability of the connection between the charging terminal (108) and the charging port (660) or the connection between the dust collection pipe (620) and the air flow pipe (130) when the mobile robot (100) is docked with the docking station (600).
[0120] Accordingly, as one embodiment of the present invention, the caster of the mobile robot (100) can be secured in the groove of the restraint plate (670) described above, thereby preventing movement of the mobile robot (100). Accordingly, the stability of docking between the docking station (600) and the mobile robot (100) according to one embodiment of the present invention can be increased, thereby facilitating charging of the mobile robot (100) and removal of dust inside the mobile robot (100).
[0121] Hereinafter, a method for removing internal dust of a mobile robot (100) through a docking station (600) while the docking station (600) and the mobile robot (100) are docked will be described in more detail.
[0122] In a mobile robot (100) according to one embodiment of the present invention, the air flow pipe (130) can move backward when one end is coupled with the dust collection pipe (620) located at the front of the docking station (600) as described above, so that the other end can be brought into close contact with the front of the control box (102). In addition, the dust collection motor (630) of the docking station (600) is driven, thereby allowing the internal air of the control box (102) to be sucked in.
[0123] Here, the mobile robot (100) according to one embodiment of the present invention may include a first guide pin (103) formed by protruding from the front edge of the control box (102) and an elastic member (104) positioned on the first guide pin (103). In addition, the air flow pipe (130) may include a first guide hole (131) into which the first guide pin (103) is inserted at the other end and which comes into contact with the elastic member (104).
[0124] Referring to FIGS. 7 and 8 together, the air flow pipe (130) of the mobile robot (100) can be coupled to the dust collection pipe (620) of the docking station (600), and as the mobile robot (100) moves forward, the air flow pipe (130) can move backward so that the other end of the air flow pipe (130) can be in close contact with the front of the control box (102). At this time, the first guide pin (103), the elastic member (104), and the first guide hole (131) described above can serve to guide the movement of the air flow pipe (130).
[0125] In addition, the air passage pipe (130) may include a rubber member (132) formed along the circumference of the other end. Through this, the air passage pipe (130) can be completely pressed against the front of the control box (102) so that no gap occurs between the other end of the air passage pipe (130) and the front of the control box (102). In this state, the dust collection motor (630) of the docking station (600) described above can be driven to suck in the internal air of the control box (102).
[0126] Additionally, the mobile robot (100) according to one embodiment of the present invention can detect the docked state of the air flow pipe (130) and the dust collection pipe (620) through the sensing unit (140) and the control unit (180) described above with reference to FIG. 2. In addition, the sensing unit (140) and the control unit (180) can detect whether the other end of the air flow pipe (130) is completely in contact with the front of the control box (102). In addition, the control unit (180) controls the driving unit (170) of the mobile robot (100) to move the mobile robot (100) and move the mobile robot (100) so that the other end of the air flow pipe (130) is completely in contact with the front of the control box (102) in a state where the air flow pipe (130) and the dust collection pipe (620) are coupled.
[0127] FIGS. 9 and 10 are drawings for explaining a support bracket (105) that supports the lower portion of an air flow pipe (130) in a mobile robot (100) according to one embodiment of the present invention. FIG. 11 is a perspective view illustrating an air flow pipe (130) of a mobile robot (100) according to one embodiment of the present invention. And FIG. 12 is a drawing for explaining that internal air is discharged through an air flow pipe (130) in a mobile robot (100) according to one embodiment of the present invention.
[0128] First, FIGS. 9 and 10 are drawings for explaining a support bracket (105) that supports the lower part of an air passage pipe (130) in a mobile robot (100) according to one embodiment of the present invention. FIG. 9 illustrates a second guide hole (106) formed in the front-back direction (x-axis direction, FIG. 4) in the support bracket (105), and FIG. 10 illustrates a second guide pin (133) formed in the lower part of the air passage pipe (130) and inserted into the second guide hole (106).
[0129] Referring to FIG. 8 together, in order to efficiently exhaust air inside the control box (102) of the mobile robot (100) while the mobile robot (100) and the docking station (600) are docked, the other end of the air flow pipe (130) needs to be completely in contact with the front of the control box (102).
[0130] To this end, as described above, the mobile robot (100) according to one embodiment of the present invention may include a first guide pin (103), an elastic member (104), and a first guide hole (131), and may also include a rubber member (132) formed along the other end of the air flow pipe (130).
[0131] In addition, in a mobile robot (100) according to one embodiment of the present invention, the body (101) may include a support bracket (105) that supports the lower part of the air flow pipe (130) and prevents the air flow pipe (130) from flowing in the left-right direction (y-axis direction, FIG. 4) perpendicular to the forward-backward direction (x-axis direction, FIG. 4).
[0132] Here, the support bracket (105) may include a second guide hole (106) formed in the front-back direction (x-axis direction, FIG. 4). In addition, the air flow pipe (130) may include a second guide pin (133) formed at the bottom and introduced into the second guide hole (106). Through this, the air flow pipe (130) can be made to move only in the front-back direction (x-axis direction, FIG. 4), and as described above, the other end of the air flow pipe (130) can be made to be completely in contact with the front of the control box (102).
[0133] FIG. 11 is a drawing illustrating an air flow pipe (130) of a mobile robot (100) according to one embodiment of the present invention, and is a drawing for explaining the characteristics of the shape of the air flow pipe (130) more specifically.
[0134] According to one embodiment of the present invention, the air flow pipe (130) of the mobile robot (100) may have a width at one end greater than the width at the other end. Accordingly, w1 may have a value greater than w2, and h1 may have a value greater than h2.
[0135] This is because the other end of the air flow pipe (130) is pressed against the front of the control box (102), one end of the air flow pipe (130) is connected to the dust collection pipe (620) of the docking station (600), and the internal air of the control box (102) is sucked toward the dust collection pipe (620) of the docking station (600) through the air flow pipe (130).
[0136] That is, as shown in Fig. 12, the internal air of the control box (102) can be efficiently sucked in through a shape in which the width of the air passage pipe (130) narrows from one end to the other.
[0137] In addition, the air flow pipe (130) of the mobile robot (100) according to one embodiment of the present invention can be formed to have a curved shape, for example, an S-shaped shape, as illustrated in FIG. 11. Through this, the air flow can be made smooth, and the internal air of the control box (102) can be sucked in more efficiently.
[0138] Additionally, the mobile robot (100) according to one embodiment of the present invention may include at least one blower (107) positioned in front of the control box (102). Here, the blower (107) may rotate to prevent heat generation from electronic components mounted in the control box (102) when the mobile robot (100) moves for normal operation as described above, and may serve to cool the internal space by blowing air toward the inside of the control box (102).
[0139] In addition, referring to FIG. 12, the blower (107) of the mobile robot (100) according to one embodiment of the present invention can play an assisting role when the internal air of the control box (102) is sucked in. That is, the blower (107) can rotate so that the internal air of the control box (102) is sucked into the air passage (130). Therefore, the mobile robot (100) according to one embodiment of the present invention can more efficiently discharge the internal air of the control box (102) through the blower (107). In addition, the rotation of the blower (107) described above can be controlled through the control unit (180) described above with reference to FIG. 2.
[0140] In summary, the docking station, mobile robot, and device including the same according to the present invention can remove dust inside the mobile robot by sucking air through the dust collecting motor of the docking station while the dust collecting pipe of the docking station and the air duct of the mobile robot are connected. In addition, the docking station can purify the air by collecting dust in the sucked air through the dust collecting filter and discharging the air from which dust has been removed to the outside through the dust collecting motor.
[0141] The above detailed description should not be construed as limiting in any respect and should be considered illustrative only. The scope of the present invention should be determined by a reasonable interpretation of the appended claims, and all modifications within the equivalent scope of the present invention are intended to be included within the scope of the present invention.
