Depending on the embodiments, a plurality of "parts," "modules," and "components" may be implemented as a single component, or a single "part," "module," or "component" may include a plurality of components.

[0057] Terms such as "first," "second," or "first" or "second" are used simply to distinguish a component from another component and do not limit the components in other aspects (e.g., importance or order).

[0058] Where any (e.g., 1st) component is referred to as "coupled" or "connected" to another (e.g., 2nd) component, with or without the terms "functionally" or "communicationly," it means that said any component may be connected to said other component directly (e.g., via a wire), wirelessly, or through a third component.

[0059] Terms such as "include" or "have" are intended to specify the existence of the features, numbers, steps, actions, components, parts, or combinations thereof described in this document, and do not preclude the existence or addition of one or more other features, numbers, steps, actions, components, parts, or combinations thereof.

[0060] When it is said that a component is "connected," "combined," "supported," or "in contact" with another component, this includes not only cases where the components are directly connected, combined, supported, or in contact, but also cases where they are indirectly connected, combined, supported, or in contact through a third component.

[0061] When it is said that a component is located "on" another component, this includes not only cases where one component is in contact with the other, but also cases where another component exists between the two components.

For example, "up" and "down" may each be defined based on the Z-axis shown in the drawings.

[0063] An electronic device (1) according to various embodiments of the present disclosure may perform specific tasks while in a driving state. For example, the electronic device (1) may include a projector (1a, see FIGS. 1 to 3) movably provided to project an image onto any area, or a robot vacuum cleaner (1b, see FIGS. 19 to 21) movably provided to perform a cleaning function in any area. However, the present disclosure is not limited to the examples described above, and the present disclosure may be applied to any device capable of autonomous driving in addition to the examples described above. The electronic device (1) may be referred to as an autonomous driving robot (1).

[0064] FIG. 1 illustrates an electronic device according to one embodiment of the present disclosure in a driving state. FIG. 2 illustrates an electronic device according to one embodiment of the present disclosure in a non-driving state. FIG. 3 illustrates the interior of an electronic device according to one embodiment of the present disclosure.

[0065] Referring to FIGS. 1 to 3, a projector (1a) is described as an example of an electronic device (1).

[0066] The projector (1a) can project an image onto any area. For example, the projector (1a) can project an image onto a screen, wall, floor, ceiling, furniture, etc.

[0067] The projector (1a) may include a housing (10). The housing (10) may form the overall appearance of the projector (1a). The housing (10) may be provided to accommodate various components of the projector (1a). For example, the housing (10) may be provided to accommodate a light source, an optical member for guiding light emitted from the light source toward a projection lens (30), and an image processing device (e.g., including an LCD panel, a DMD chip and / or an LCoS panel). For example, the housing (10) may be provided to accommodate at least a part of the lifting assembly (40) described later (see FIG. 3). The housing (10) may be referred to as a main body (10), a case (10), etc.

[0068] The projector (1a) may include a projection lens (30). The projection lens (30) may be configured to project an image generated by the projector (1a) onto an arbitrary area. The projection lens (30) may be focused so that the image can be seen clearly. The projection lens (30) may adjust the size of the image according to the projection distance.

[0069] The projector (1a) may include a driving device (20). The driving device (20) may be detachably mounted on the lower part of the housing (10). The driving device (20) may include at least one wheel (21) mounted on the lower part of the housing (10) and arranged to move the housing (10). As an example, the driving device (20) may include a pair of wheels (21). The driving device (20) may include a wheel drive unit for driving the wheels (21).

[0070] The projector (1a) may include a lifting assembly (40). At least a portion of the lifting assembly (40) may be placed inside the projector (1a) (see FIG. 3). The lifting assembly (40) may include a sensor (100) for detecting obstacles and components for raising and lowering the sensor (100). The lifting assembly (40) may also be referred to as a sensor assembly (40) or a pop-up assembly (40).

[0071] The lifting assembly (40) may be provided in a first state (S1, see FIG. 1) or a second state (S2, see FIG. 2). The lifting assembly (40) may be switchable between the first state (S1) and the second state (S2).

[0072] When the sensor (100) operation is required (e.g., when the projector (1a) is in a driving state), the lifting assembly (40) may be provided in a first state (S1). While the lifting assembly (40) is in the first state (S1), the sensor (100) may be in a first position (P1) protruding from the housing (10). For example, the sensor (100) may protrude from the top of the housing (10) through an opening (11) of the housing (10). When the projector (1a) is in a driving state, the sensor (100) is exposed outside the housing (10) and can detect an object located around the projector (1a).

[0073] When the operation of the sensor (100) is not required (e.g., when the projector (1a) is not in a driving state), the lifting assembly (40) may be provided in a second state (S2). While the lifting assembly (40) is in the second state (S2), the sensor (100) may be in a second position (P2) that is accommodated inside the housing (10) (see FIG. 8). While the lifting assembly (40) is in the second state (S2), the sensor (100) may be retracted into the housing (10). While the projector (1a) is not in a driving state, the sensor (100) may not be exposed outside the housing (10). When the projector (1a) is not in a driving state, the sensor (100) may be hidden inside the housing (10).

[0074] The lifting assembly (40) may include a sensor cover (150) provided to cover the upper part of the sensor (100). When the sensor (100) is in a second position (P2) (i.e., when the projector (1a) is not in a driving state), the sensor cover (150) may be provided to form part of the exterior of the projector (1a) (see FIG. 2). The sensor cover (150) may be connected to the housing (10) without a step within a predetermined error range. The upper surface of the sensor cover (150) may be provided to be smoothly connected to the outer surface of the housing (10). The sensor cover (150) and the housing (10) may form a substantially seamless exterior. The sensor cover (150) may have a size corresponding to the opening (11) of the housing (10).

[0075] In summary, depending on whether the projector (1a) is in a driving state, the lifting assembly (40) may be provided in a first state (S1, see FIG. 1) or a second state (S2, see FIG. 2). The projector (1a) may be in a driving state when it is in a mode configured to drive using the sensor (100), regardless of whether it is actually moving. Similarly, the projector (1a) may not be in a driving state when it is in a mode not configured to drive or in a driving mode that does not use the sensor (100). Thus, the user can easily recognize whether the projector (1a) is in a driving state. Additionally, the aesthetic appeal of the projector (1a) may be enhanced.

[0076] FIG. 4 illustrates an exploded view of a lifting assembly according to one embodiment of the present disclosure.

[0077] The lifting assembly (40) may include a sensor (100). The sensor (100) may be configured to detect obstacles (external objects) (e.g., objects, people, pets, etc.). The sensor (100) may be configured to detect obstacles located on the driving path of the projector (1a) or located around the projector (1a). The sensor (100) may be configured to detect the location of the obstacle, the distance from the obstacle, etc. The sensor (100) may be referred to as an obstacle detection sensor (100).

[0078] For example, the sensor (100) may include a Light Detection and Ranging (Lidar) sensor. The sensor (100) can emit light (pulsed laser) outward and receive light in a preset direction among the light reflected from an external object. The sensor (100) can rotate approximately 360 degrees clockwise or counterclockwise. Since the sensor (100) can emit light and receive reflected light approximately 360 degrees, it can detect external objects from all directions. However, the present disclosure is not limited to the examples described above, and the sensor (100) may include various sensors capable of detecting obstacles.

[0079] The sensor (100) may include a support mounting portion (110). The support mounting portion (110) may also be referred to as a support support (110). The support mounting portion (110) may be provided to be mountable to a supporter (200) to be described later. For example, the support mounting portion (110) includes a mounting hole (111), and a mounting projection (240) of the supporter (200) may be inserted into the mounting hole (111). Thus, the sensor (100) can be stably supported on the supporter (200).

[0080] The lifting assembly (40) may include a sensor cover (150). The sensor cover (150) may be provided to cover the upper part of the sensor (100). The sensor cover (150) may be detachably coupled to the upper part of the sensor (100) or formed integrally with the sensor (100).

[0081] The lifting assembly (40) may include a supporter (200). The supporter (200) may be provided to support the sensor (100). The sensor (100) may be seated on the supporter (200). The supporter (200) may also be referred to as a support frame (200), a support assembly (200), a support frame assembly (200), etc.

[0082] The supporter (200) may be configured to be movable in a vertical direction. The supporter (200) may move in a vertical direction (Z direction) together with the sensor (100). As the supporter (200) moves in a vertical direction, the sensor (100) supported by the supporter (200) may also move in a vertical direction. The supporter (200) may be configured to move the sensor (100) up and down.

[0083] As the supporter (200) moves along the vertical direction, the lifting assembly (40) can be switched between a first state (S1, see FIG. 1) and a second state (S2, see FIG. 2). As the supporter (200) moves along the vertical direction, the sensor (100) can be switched between a first position (P1, see FIG. 5) protruding from the top of the housing (100) and a second position (P2, see FIG. 8) accommodated inside the housing (100). The sensor (100) can be moved between the first position (P1, see FIG. 5) and the second position (P2, see FIG. 8). The sensor (100) can be configured to move vertically between the first position (P1, see FIG. 5) and the second position (P2, see FIG. 8). The sensor (100) can move downward from the first position (P1) to reach the second position (P2). The sensor (100) can move upward from the second position (P2) to reach the first position (P1).

[0084] For example, the supporter (200) may include a bottom portion (201) on which the sensor (100) is placed, and a side wall portion (202) extending upward from the bottom portion (201). The supporter (200) may form a space for accommodating at least a portion of the sensor (100). The space may be formed by the bottom portion (201) and the side wall portion (202).

[0085] The supporter (200) may include a guide hole (210). The guide hole (210) may be configured to allow the shaft (310), which will be described later, to be inserted. With the shaft (310) inserted into the guide hole (210), the supporter (200) may move along the vertical direction.

[0086] For example, the supporter (200) may include a first guide hole (211). The first guide hole (211) may include a shape that is approximately laterally (e.g., in the Y direction). The first guide hole (211) may include an approximately elliptical shape. A first shaft (311), which will be described later, can be inserted into the first guide hole (211). A detailed description of the first guide hole (211) will be provided later.

[0087] For example, the supporter (200) may include a second guide hole (212). The second guide hole (212) may be spaced apart from the first guide hole (211). The second guide hole (212) may have a roughly circular shape. A second shaft (312), which will be described later, can be inserted into the second guide hole (212). A detailed description of the second guide hole (212) will be provided later.

[0088] The supporter (200) may include a hole forming portion (220). The hole forming portion (220) may be provided in the side wall portion (202). The hole forming portion (220) may be provided to form a guide hole (210). For example, the hole forming portion (220) may include a roughly cylindrical shape.

[0089] For example, the supporter (200) may include a first hole forming part (221) provided to form a first guide hole (211).

[0090] For example, the supporter (200) may include a second hole forming part (222) provided to form a second guide hole (212). The second hole forming part (222) may be spaced apart from the first hole forming part (221).

[0091] The supporter (200) may include a fixing hook (230). The fixing hook (230) may be formed on the side wall (202). The fixing hook (230) may be provided to fix the supporter mounting portion (110). The supporter mounting portion (110) may be provided to be hooked onto the fixing hook (230). Thus, the sensor (100) may not detach from the supporter (200) while it is seated on the supporter (200). The sensor (100) may not easily shake while moving while supported by the supporter (200). The sensor (100) may move stably along the vertical direction.

[0092] The supporter (200) may include a mounting projection (240). The mounting projection (240) may be formed on the bottom portion (201). The mounting projection (240) may be provided to be insertable into the mounting hole (111). Thus, the sensor (100) may not detach from the supporter (200) while seated on the supporter (200). The sensor (100) may not easily shake while moving while supported by the supporter (200). The sensor (100) may move stably along the vertical direction.

[0093] The supporter (200) may include a substrate mounting portion (250). The substrate mounting portion (250) may be formed on the side wall portion (202). A circuit board (730), to be described later, may be detachably coupled to the substrate mounting portion (250) of the supporter (200). For example, the circuit board (730) may be screw-coupled to the substrate mounting portion (250). However, the present disclosure is not limited to the above-described example, and the circuit board (730) may be coupled to the substrate mounting portion (250) through various previously known methods.

[0094] The lifting assembly (40) may include a shaft (310). The shaft (310) may be provided to guide the movement of the supporter (200). The shaft (310) may extend approximately along a vertical direction. With the shaft (310) inserted into the guide hole (210) of the supporter (200), the supporter (200) may move along the vertical direction.

[0095] For example, the lifting assembly (40) may include a first shaft (311). The first shaft (311) may be provided to be insertable into a first guide hole (211). The first shaft (311) may be provided to be inserted into the first guide hole (211) to guide the movement of the supporter (200). The first shaft (311) may extend along a vertical direction.

[0096] For example, the lifting assembly (40) may include a second shaft (312). The second shaft (312) may be provided to be insertable into a second guide hole (212). The second shaft (312) may be provided to be inserted into the second guide hole (212) to guide the movement of the supporter (200). The second shaft (312) may extend along a vertical direction.

[0097] The shaft (310) may be provided as a component of the base (300) to be described later. For example, the shaft (310) may be provided to be pressed into the base (300).

The supporter (200) may be provided to be lifted relative to the base (200).

[0099] The lifting assembly (40) may include a power transmission member (500). The power transmission member (500) may be mechanically connected between the motor (400) and the supporter (200). The power transmission member (500) may be provided to transmit power to the supporter (200). The supporter (200) may move along a vertical direction by means of power transmitted from the power transmission member (500). The power transmission member (500) may receive power from the motor (400), which will be described later, and provide the power received from the motor (400) to the supporter (200). The power transmission member (500) may convert the rotational motion of the motor (400) into linear motion of the supporter (200).

[0102] The second gear (520) can provide power generated by the motor (400) to the first gear (510). The first gear (510) can provide power provided from the second gear (520) to the supporter (200). As the motor (400) rotates, the second gear (520) connected to the motor (400) can rotate. As the second gear (520) rotates, the first gear (510) engaged with the second gear (520) can move in a vertical direction. The supporter (200) formed with the first gear (510) can move along the vertical direction. Depending on the rotation direction of the motor (400), the supporter (200) can move upward (+Z direction) or downward (-Z direction).

[0105] The lifting assembly (40) may include a motor cover (450). The motor cover (450) may be configured to dampen and / or suppress (e.g., mitigate) vibrations occurring in the motor (400).

[0106] The lifting assembly (40) may include a bracket (600). The bracket (600) may be provided to secure the motor (400) to the base (300). The motor (400) may be mounted to the base (300) via the bracket (600). For example, the bracket (600) may be detachably mounted to the base (300), and the motor (400) may be detachably mounted to the bracket (600). For example, the bracket (600) may be screw-coupled to the base (300), and the motor (400) may be coupled to the bracket (600). However, the present disclosure is not limited to the examples described above, and the bracket (600) may secure the motor (400) to the base (300) through various known methods.

[0108] The lifting assembly (40) may include a sensor (710). The sensor (710) may be detachably mounted on a supporter (200). For example, the sensor (710) may be mounted on a circuit board (730), and the circuit board (730) may be coupled to a board mounting portion (250) of the supporter (200). While the sensor (710) is mounted on the supporter (200), the sensor (710) may move together with the supporter (200).

[0112] Sensors (710) and (720) can limit the range of movement of the supporter (200). When the sensor (710) contacts the upper surface (610) of the bracket (600), the sensor (100) supported by the supporter (200) can reach a first position (P1). When the sensor (720) contacts the lower surface (620) of the bracket (600), the sensor (100) supported by the supporter (200) can reach a second position (P2). When the sensor (100) reaches the first position (P1) or the second position (P2), movement of the supporter (200) in the vertical direction may be limited. A detailed explanation thereof will be provided later.

[0113] The lifting assembly (40) may include a circuit board (730). Sensors (710) and (720) may be mounted on the circuit board (730). The circuit board (730) may be detachably mounted on the board mounting portion (250) of the supporter (200).

[0114] Meanwhile, for the purpose of distinguishing between the sensors, sensor (100) may be referred to as the first sensor (100), sensor (710) as the second sensor (710), and sensor (720) as the third sensor (720). The ordinal numbers "first," "second," and "third" are merely for distinguishing each sensor and do not limit their configurations.

[0115] The lifting assembly (40) may include a stopper (800). The stopper (800) may be coupled to the shaft (310). The stopper (800) may be coupled to the outer surface of the shaft (310).

While the stopper (800) is in contact with the supporter (200), the upward movement of the supporter (200) may be restricted. For example, the stopper (800) may include an E-ring.

[0116] For example, the lifting assembly (40) may include a first stopper (810) coupled to a first shaft (311).

[0118] FIG. 5 illustrates a first state of a lifting assembly according to one embodiment of the present disclosure. FIG. 6 is a cross-sectional view along the line AA' indicated in FIG. 5. FIG. 7 is a cross-sectional view along the line BB' indicated in FIG. 5.

[0119] Referring to FIGS. 5 to 7, the first state (S1) of the lifting assembly (40) will be described.

[0120] While the electronic device (1) is moving, the lifting assembly (40) may be provided in a first state (S1). While the lifting assembly (40) is in the first state (S1), the first sensor (100) may be in a first position (P1). While the first sensor (100) is in the first position (P1), the first sensor (100) may protrude from the top of the housing (10) (see FIG. 1). While the first sensor (100) is in the first position (P1), the first sensor (100) may be exposed from the housing (10) (see FIG. 1). For example, when the supporter (200) is located at the highest point, the first sensor (100) may be in the first position (P1).

[0121] Referring to FIG. 5, a stopper (800) may be provided to contact the supporter (200) to restrict the supporter (200) from moving upward when the first sensor (100) is at the first position (P1). The stopper (800) may press the supporter (200) downward. The supporter (200) may be unable to move upward from the first position (P1) by interfering with the stopper (800). For example, the first stopper (810) may be provided to contact the first hole forming part (221). For example, the second stopper (820) may be provided to contact the second hole forming part (222).

[0122] Referring to FIG. 6, the first gear (510) may include an upper portion (511) and a lower portion (512). The lower portion (512) may extend downward from the upper portion (511). The upper portion (511) may be an upper portion based on approximately half the length along the vertical direction of the first gear (510). The lower portion (512) may be a lower portion based on approximately half the length along the vertical direction of the first gear (510). For example, while the first sensor (100) is in the first position (P1), the lower portion (512) of the first gear (510) may mesh with the second gear (520).

[0123] Referring to FIG. 7, when the first sensor (100) is at the first position (P1), the second sensor (710) may be arranged to contact the upper surface (610) of the bracket (600). The second sensor (710) may generate a touch signal based on contact with the upper surface (610) of the bracket (600). The second sensor (710) may detect that the first sensor (100) has reached the first position (P1). For example, the second sensor (710) may detect that the supporter (200) has reached the highest point.

[0124] FIG. 8 illustrates a second state of a lifting assembly according to one embodiment of the present disclosure. FIG. 9 is a cross-sectional view along the line CC' indicated in FIG. 8. FIG. 10 is a cross-sectional view along the line DD' indicated in FIG. 8.

[0125] Referring to FIGS. 8 to 10, the second state (S2) of the lifting assembly (40) will be described.

[0126] While the electronic device (1) is stopped, the lifting assembly (40) may be provided in a second state (S2). While the lifting assembly (40) is in the second state (S2), the first sensor (100) may be in a second position (P2). While the first sensor (100) is in the second position (P2), the first sensor (100) may be placed inside the housing (10) (see FIG. 2). While the first sensor (100) is in the second position (P2), the first sensor (100) may not be exposed outside the housing (10) (see FIG. 2). For example, when the supporter (200) is located at the lowest point, the first sensor (100) may be in the second position (P2).

[0127] When the first sensor (100) is at the second position (P2), the supporter (200) can be seated on the base (300). When the first sensor (100) is at the second position (P2), the supporter (200) can be supported by the base (300). The supporter (200) may not be able to move downward from the second position (P2) due to interference with the base (300).

[0128] Referring to FIG. 9, for example, while the first sensor (100) is in the second position (P2), the upper part (511) of the first gear (510) can be engaged with the second gear (520).

[0129] Referring to FIG. 10, when the first sensor (100) is at the second position (P2), the third sensor (720) may be arranged to contact the lower portion (620) of the bracket (600). The third sensor (720) may generate a touch signal based on contact with the lower portion (620) of the bracket (600). The third sensor (720) may detect that the first sensor (100) has reached the second position (P2). For example, the third sensor (720) may detect that the supporter (200) has reached the lowest point.

[0130] FIG. 11 is a control block diagram of an electronic device according to one embodiment of the present disclosure.

[0131] Referring to FIG. 11, an electronic device (1) according to one embodiment of the present disclosure may include a first sensor (100), a second sensor (710), a third sensor (720), a driving device (20), a motor (400), and a control unit (900).

[0132] The control unit (900) can control the operation of the electronic device (1). The control unit (900) can be electrically connected to various components of the electronic device (1).

[0133] The control unit (900) may include hardware such as a CPU, a Micom, or memory, and software such as a control program. For example, the control unit (900) may include at least one memory (920) that stores data in the form of an algorithm or program for controlling the operation of components of the electronic device (1). For example, the control unit (900) may include at least one processor (910) that performs operations using data stored in at least one memory (920). The memory (920) and the processor (910) may each be implemented as separate chips. The processor (910) may include one or more processor chips or one or more processing cores. The memory (920) may include one or more memory chips or one or more memory blocks. Additionally, the memory (920) and the processor (910) may be implemented as a single chip.

[0134] The first sensor (100) may be configured to detect obstacles. The first sensor (100) may collect information about the surrounding environment. The first sensor (100) may generate data about obstacles (hereinafter referred to as obstacle data) and transmit the obstacle data to the control unit (900). The obstacle data generated by the first sensor (100) may include location information of the obstacle and / or distance information to the obstacle.

[0135] The control unit (900) can identify external objects located around the electronic device (1) based on obstacle data obtained through the first sensor (100). For example, the memory (920) of the control unit (900) can store an artificial intelligence model for detecting external objects based on obstacle data.

[0136] The second sensor (710) may be provided to contact the upper surface (610) of the bracket (600) when the first sensor (100) reaches the first position (P1). The second sensor (710) may generate a touch signal based on contact with the upper surface (610) of the bracket (600) and transmit the touch signal to the control unit (900).

[0137] The control unit (900) can identify that the first sensor (100) has reached a first position (P1) (e.g., the highest point) based on a touch signal obtained through the second sensor (710). The control unit (900) can stop the operation of the motor (400) based on receiving a touch signal from the second sensor (710). The control unit (900) can stop the operation of the motor (400) based on the second sensor (710) coming into contact with the upper surface (610). As the first sensor (100) reaches the first position (P1), the power transmission member (500) may not transmit power to the supporter (200). Thus, the first sensor (100) may not move upward above the first position (P1).

[0138] The third sensor (720) may be configured to contact the lower portion (620) of the bracket (600) when the first sensor (100) reaches the second position (P2). The third sensor (720) may generate a touch signal based on contact with the lower portion (620) of the bracket (600) and transmit the touch signal to the control unit (900).

[0139] The control unit (900) can identify that the first sensor (100) has reached a second position (P2) (e.g., the lowest point) based on a touch signal obtained through the third sensor (720). The control unit (900) can stop the operation of the motor (400) based on receiving a touch signal from the third sensor (720). The control unit (900) can stop the operation of the motor (400) based on the third sensor (720) coming into contact with the lower portion (620). As the first sensor (100) reaches the second position (P2), the power transmission member (500) may not transmit power to the supporter (200). Thus, the first sensor (100) may not move downward below the second position (P2).

[0140] The driving device (20) can move the main body of the electronic device (1). The driving device (20) may include a wheel and a wheel drive unit, but the present disclosure is not limited thereto. In some embodiments, the driving device (20) may include a conveyor, a track, or other means of movement.

[0141] The control unit (900) can control the driving device (20). By controlling the driving device (20), the control unit (900) can control the driving direction, driving speed, etc. of the electronic device (1).

[0142] FIG. 12 illustrates a portion of a lifting assembly according to one embodiment of the present disclosure. FIG. 13 is a front view of the lifting assembly illustrated in FIG. 12 according to one embodiment of the present disclosure. FIG. 14 is a cross-sectional view along the line EE' indicated in FIG. 12 according to one embodiment of the present disclosure. FIG. 15 is an enlarged view of portion F indicated in FIG. 14 according to one embodiment of the present disclosure. FIG. 16 is an enlarged view of portion G indicated in FIG. 14 according to one embodiment of the present disclosure.

[0143] A power transmission member (500) is positioned on the lateral side of a supporter (200) to transmit power to the supporter (200). The supporter (200) can move along the vertical direction by means of the power transmitted from the power transmission member (500). A sensor (100) supported by the supporter (200) can also move along the vertical direction. For example, as the second gear (520) rotates, the first gear (510) meshed with the second gear (520) can move along the vertical direction. Thus, the supporter (200) formed with the first gear (510) can move along the vertical direction.

[0144] The power transmission member (500) can apply force to the supporter (200). Since the power transmission member (500) is positioned on the side of the supporter (200), the power transmission member (500) can apply force (P) laterally in addition to force in the vertical direction (Z direction). The power transmission member (500) can be positioned on the side of the supporter (200) to apply force (P) to the supporter (200) in a first direction (D1). As the first gear (510) and the second gear (520) of the power transmission member (500) positioned on the side of the supporter (200) mesh and operate, force (P) can be generated. For example, a force (P) may be generated by friction between the teeth of the first gear (510) and the teeth of the second gear (520), the meshing angle between the first gear (510) and the second gear (520), etc.

[0145] For example, the first direction (D1) may intersect the vertical direction (Z direction). The first direction (D1) may be a direction that intersects the direction of the rotation axis (400a, see FIG. 4) of the motor (400). The first direction (D1) may be approximately the horizontal direction (Y direction).

[0146] For example, the second direction (D2) may intersect the first direction (D1). The second direction (D2) may intersect the vertical direction (Z direction). The second direction (D2) may correspond to the direction of the rotation axis (400a) of the motor (400). The second direction (D2) may be a direction parallel to the direction of the rotation axis (400a) of the motor (400). In the example of FIG. 12, the second direction (D2) may correspond approximately to the second horizontal direction (X direction), but the present disclosure is not limited thereto.

[0147] As the power transmission member (500) applies a lateral force (P) to the supporter (200), the shaft (310) may be eccentric within the guide hole (210). As the supporter (200) receives the force (P) from the power transmission member (500), the shaft (310) may interfere with the supporter (200) (e.g., the hole forming part (220)), which may hinder the movement of the supporter (200). That is, the supporter (200) may not be able to move smoothly. Additionally, the shaft (310) may be easily worn out. To solve this, the guide hole (210) may include an elongated hole shape. According to one embodiment of the present disclosure, the guide hole (210) may include an extended hole shape.

[0148] For example, referring to FIG. 15, the first guide hole (211) may have a laterally elongated shape. The first guide hole (211) may have an elongated shape along the direction in which the power transmission member (500) applies force (P) to the supporter (200). The first guide hole (211) may have an elliptical shape. The first guide hole (211) may have a major axis and a minor axis. The distance from the center (C1) of the first guide hole (211) to the edge of the first guide hole (211) may not be constant. The first guide hole (211) may have a first length (L1) along a first direction (D1) and a second length (L2) along a second direction (D2). The first guide hole (211) may have a first length (L1) extending in a direction intersecting the rotation axis (400a) of the motor (400) and a second length (L2) extending in the direction of the rotation axis (400a) of the motor (400). The first length (L1) may be larger than the second length (L2).

[0149] The shape of the first guide hole (211) described above allows the first shaft (311) to move to some extent along the first direction (D1) within the first guide hole (211) when the supporter (200) receives force (P) from the power transmission member (500). This prevents and / or reduces interference between the supporter (200) and the shaft (310). Interference between the first hole forming part (221) and the first shaft (311) can be prevented and / or reduced. The first shaft (310) can be inserted into the first guide hole (211) of the supporter (200) to minimize contact with the supporter (200). Consequently, the supporter (200) can move smoothly, and damage to the first shaft (311) can also be prevented and / or reduced. The lifespan of the lifting assembly (40) and the electronic device (1) including the lifting assembly (40) can be extended.

[0150] The shape of the first guide hole (211) described above can restrict the movement of the first shaft (311) along the second direction (D2) within the first guide hole (211) when the supporter (200) receives force (P) from the power transmission member (500). By doing so, it is possible to prevent the supporter (200) from rotating around the second shaft (312) when receiving force (P) from the power transmission member (500).

[0151] For example, referring to FIG. 16, the second guide hole (212) may have a circular shape. The diameter of the second guide hole (212) may be constant. The distance from the center (C2) of the second guide hole (212) to the edge of the second guide hole (212) may be constant. The second guide hole (212) may have a third length (L3) along the first direction (D1) and a fourth length (L4) along the second direction (D2). The second guide hole (212) may have a third length (L3) extending in a direction intersecting the rotation axis (400a) of the motor (400) and a fourth length (L4) extending in the direction of the rotation axis (400a) of the motor (400). The third length (L3) and the fourth length (L4) may be approximately the same.

[0152] The shape of the second guide hole (212) described above may restrict the movement of the second shaft (312) along the first direction (D1) and the second direction (D2) within the second guide hole (212) when the supporter (200) receives force (P) from the power transmission member (500).

[0153] One of the plurality of guide holes (210) (211) may have an elongated shape, and another of the plurality of holes (210) may have a circular shape. One of the plurality of shafts (310) (311) may be inserted into the elongated guide hole (211) to guide the movement of the supporter (200), and another of the plurality of shafts (310) (312) may be inserted into the circular guide hole (212) to guide the movement of the supporter (200). Accordingly, the supporter (200) may have one degree of freedom. That is, the supporter (200) may be configured to be movable in the vertical direction (Z direction). Meanwhile, although the drawings show two guide holes (210) and two shafts (310), the present disclosure is not limited thereto. The number of guide holes (210) and the number of shafts (310) are not limited.

[0154] FIG. 17 illustrates a motor and a motor cover according to one embodiment of the present disclosure. FIG. 18 illustrates the motor and motor cover illustrated in FIG. 17 in an exploded view.

[0155] Referring to FIGS. 17 and 18, a motor cover (450) may be provided to enclose a motor (400). The motor cover (450) may be detachably coupled to the motor (400). The motor cover (450) may be coupled to the motor (400) to dampen vibrations occurring in the motor (400). For example, the motor cover (450) may include rubber.

[0156] Vibrations may occur when the motor (400) is in operation, and vibrations generated from the motor (400) may be transmitted to the supporter (200) and the base (300). If vibrations are transmitted to the supporter (200) and the base (300), the supporter (200) may not be able to move smoothly. Additionally, the supporter (200) and / or the base (300) may be damaged by vibrations. To address this, a motor cover (450) may be configured to be coupled to the motor (400) to dampen vibrations. For example, the motor cover (450) may include a shape that covers the motor (400) along the ZY plane, and accordingly, the motor cover (450) can effectively reduce vibrations occurring along the vertical direction (Z direction) and the lateral direction (Y direction).

[0157] FIG. 19 illustrates an electronic device according to one embodiment of the present disclosure in a driving state. FIG. 20 illustrates an electronic device according to one embodiment of the present disclosure in a non-driving state. FIG. 21 illustrates an electronic device according to one embodiment of the present disclosure below.

[0158] Referring to FIGS. 19 to 21, a robot vacuum cleaner (1b) is described as an example of an electronic device (1). Components substantially identical to those shown in FIGS. 1 to 18 are given the same reference numerals, and detailed descriptions may be omitted.
