Description

Technology Field

[0001] The present disclosure relates to a docking device that maintains a robust docking state when docking different parts. Background Technology

[0003] Recently, interest in autonomous mobility devices has been increasing. Autonomous mobility devices are devices equipped with autonomous driving technology that allow them to move on their own without the user or passenger directly controlling whether to move, the direction of movement, or the speed of movement. For example, autonomous vehicles, autonomous mobile robots, and robotic vacuum cleaners can be classified as autonomous mobility devices, and they can be used in various ways depending on their purpose.

[0004] As the purposes of use for autonomous mobile devices diversify, docking systems between autonomous mobile devices are also being developed.

[0005] For example, autonomous mobile devices can individually provide indoor space, and depending on the purpose of use, multiple autonomous mobile devices can be docked via a docking system to expand the indoor space.

[0006] As another example, when manufacturing a vehicle, different parts can be combined through a docking system to ensure ease of assembly. For diverse usability, each part can be manufactured separately and then combined via the docking system, or parts can be exchanged depending on the intended use.

[0007] Thus, when assembling multiple modules, each module must be assembled with robust fastening force while ensuring ease of assembly; however, if the assembly fastening performance is compromised, gaps may occur between parts or the assembly may be released due to detachment.

[0008] In addition, modular mobile devices must ensure the ease of management of each module by considering not only the assembly process but also the disassembly process.

[0009] The matters described as background technology above are intended only to enhance understanding of the background of the present disclosure and do not constitute prior art already known to those skilled in the art. The problem to be solved

[0039] Hereinafter, various embodiments disclosed in this specification will be described in detail with reference to the attached drawings. Identical or similar components are given the same reference number regardless of the drawing symbols, and redundant descriptions thereof will be omitted.

[0041] The present disclosure relates to a docking device that enables different parts to be assembled or removed.

[0042] That is, multiple parts can be selectively assembled or separated using the docking device according to the present disclosure to suit various purposes and situations, such as mutually docking different moving devices, configuring the drive part (P1) and the variable part (P2) that provides an interior space to be detachable in a customizable vehicle by manufacturing the drive part (P1) and the variable part (P2) separately, or connecting a building and a vehicle or a building and a building. The docking device of the present disclosure can be utilized in various ways depending on the purpose and field of application.

[0043] In the present disclosure, as illustrated in FIG. 1, a driving part (P1) and a variable part (P2) for providing space are configured such that the driving part (P1) is used in common and the variable part (P2) can be selectively changed, and the changed variable part (P2) can be selectively docked to the driving part (P1) to fix or separate it.

[0044] As shown in FIGS. 2 to 4, the docking device according to the present disclosure is provided with a rotating member (200), a locking member (300), and a supporting member (400) in a housing (100), and a fixing jig (600) can be fastened to the locking member (300) of the housing (100) to be fixed.

[0045] Here, the housing (100) can be provided in the driving part (P1), and the fixed jig (600) can be provided in the variable part (P2). Through this, the driving part (P1) and the variable part (P2) can be assembled together by matching and connecting the fixed jig (600) of the variable part (P2) to the housing (100) of the driving part (P1), and the variable part (P2) can be separated from the driving part (P1) by detaching the fixed jig (600) from the housing (100). This docking structure using the housing (100) and the fixed jig (600) can be applied in various fields where two objects are selectively docked, in addition to the driving part (P1) and the variable part (P2).

[0046] In addition, the housing (100) and the fixing jig (600) may each be configured in multiple numbers to increase the fastening force when docking.

[0047] The housing (100) is installed in the drive part (P1), and a space may be formed so that a rotating member (200), a locking member (300), and a supporting member (400) can be provided inside. This housing (100) is manufactured by separating it into multiple parts and then joining them together, thereby ensuring ease of assembly of the internal parts. The multiple parts forming the housing (100) may be fixed by bolting or riveting.

[0048] A rotating member (200) is rotatably provided inside a housing (100), and a plurality of locking portions (210) may be formed along a circumferential surface. This rotating member (200) is installed to rotate inside the housing (100), and by forming a plurality of locking portions (210) on a circumferential surface, the locking member (300) moves when the locking portions (210) come into contact with the locking member (300) as the rotating member (200) rotates. As a result, the locking member (300) moves depending on whether the locking portions (210) come into contact, thereby restraining the fixing jig (600) or detaching from the fixing jig (600).

[0049] The locking member (300) is provided to be movable inwardly and outwardly within the housing (100), and when the rotating member (200) rotates, it comes into contact with the locking part (210), thereby changing its moving position. This locking member (300) is installed to move linearly within the housing (100), and when it comes into contact with the locking part (210) of the rotating member (200), it moves outward from the housing (100), and when it moves away from the locking part (210), it moves inward into the housing (100), thereby enabling the operation to be implemented.

[0050] Additionally, the locking member (300) is formed such that one end is exposed to the outside and the fixing jig (600) can be fastened, thereby allowing selective restraint of the fixing jig (600). The other end of the locking member (300) moves linearly inside the housing (100) and is connected to a support member (400) so that it can be moved in a specific direction by the support member (400).

[0051] The support member (400) may be composed of a spring, and various embodiments may be applied as long as force is applied in any direction other than the spring. The support member (400) may be provided to be connected to the other end of the locking member (300) inside the housing (100) and may generate a force to move the locking member (300) in the inner direction of the housing (100). Through this support member (400), the locking member (300) can maintain a state of restraining the fixing jig (600).

[0052] Thus, the docking device of the present disclosure can selectively assemble different parts by selectively connecting the housing (100) and the fixing jig (600).

[0053] In one embodiment, as shown in FIG. 5, when the rotating member (200) is rotated and the locking member (300) is pulled out of the housing (100) by the locking member (210), the fixing jig (600) becomes connectable to the locking member (300). Here, as shown in FIG. 6, when the rotating member (200) is further rotated and the locking member (210) is detached from the locking member (300), the locking member (300) is drawn into the housing (100) by the supporting member (400) and can restrain the fixing jig (600).

[0054] Thus, in the present disclosure, docking convenience is ensured by the locking member (300) restraining the fixed jig (600) or the locking member (300) detaching from the fixed jig (600) solely by rotating the rotating member (200) when assembling or removing the housing (100) and the fixed jig (600), and the fastening force between the housing (100) and the fixed jig (600) can be secured by the support member (400).

[0056] To explain the above-described disclosure in detail, the housing (100) has a first space (110) in which a rotating member (200) is provided and a second space (120) in which a locking member (300) is provided, and the first space (110) and the second space (120) are partially connected so that the locking member (300) can come into contact with the rotating member (200) of the first space (110) through the portion connected in the second space (120).

[0057] Referring to FIG. 3, the housing (100) has a first space (110) and a second space (120) formed inside, and the first space (110) and the second space (120) are formed so that a part of them are connected.

[0058] A rotating member (200) is provided in the first space (110), and the first space (110) can be formed in a circular shape to match the rotation radius of the rotating member (200).

[0059] A locking member (300) is provided in the second space (120), and the second space (120) may be formed to extend in a straight line so that the locking member (300) can move in a straight line. For example, the second space (120) may be in a rectangular shape.

[0060] Additionally, in the case of the first space (110) and the second space (120), a portion is formed to be in communication with each other, so that the locking member (300) can come into contact with the rotating member (200) through the connected portion. That is, the locking member (300) is provided in the second space (120), and a portion of the locking member (300) extends to the first space (110) through the connected portion of each space and can come into contact with the rotating member (200). Through this, the locking member (300) can move in a linear motion in conjunction with the rotational movement of the rotating member (200).

[0062] Meanwhile, the housing (100) is provided with a rotating shaft portion (130) on which a rotating member (200) is rotatably mounted, and a through portion (140) may be formed on the central axis of the rotating shaft portion (130).

[0063] The rotation shaft portion (130) may be provided in the first space (110) of the housing (100) and connected to penetrate the center of the rotating member (200) so that the rotating member (200) can be rotated through the rotation shaft portion (130).

[0064] Additionally, the housing (100) may have a through-hole (140) formed at a position that matches the central axis of the rotational shaft (130), so that the inside and outside can be open. The through-hole (140) may be composed of a hole and is positioned to match the rotational shaft (130), thereby allowing the internal rotating member (200) to be operated from the outside of the housing (100).

[0065] Specifically, as illustrated in FIG. 4, the rotational shaft portion (130) may have a first support portion (131) in the shape of a disc formed thereon, and the rotational member (200) may have a first insertion portion (220) formed therein so that the first support portion (131) is inserted therein.

[0066] In the case of the first support portion (131), it is formed in the shape of a disc, and the first insertion portion (220) of the rotating member (200) is also formed in a circular shape, so that when the first support portion (131) of the rotation shaft portion (130) is inserted into the first insertion portion (220) of the rotating member (200), the rotating member (200) can be rotated through the rotation shaft portion (130). A bearing structure may be applied between the first support portion (131) and the first insertion portion (220).

[0067] Additionally, a ring-shaped groove or protrusion is formed on the opposite side of the housing (100) where the rotational shaft portion (130) is provided, and a ring-shaped protrusion or groove is formed on the opposite side of the rotating member (200) facing the rotational shaft portion (130), so that the rotational member (200) can be guided to rotate not only through the rotational shaft portion (130) but also through the housing (100). In this way, one side of the rotating member (200) is matched to the rotational shaft portion (130) and rotated via the rotational shaft portion (130), and the rotational movement of the rotating member (200) can be stabilized through a guide structure (g) connected to the housing (100) on the other side.

[0068] Meanwhile, the present disclosure may further include an operating member (500) for adjusting the rotation angle of the rotating member (200).

[0069] The operating member (500) is provided to be removable in the through-hole (140) of the housing (100), and when inserted into the through-hole (140), it is connected to the rotating member (200) and can be rotated together with the rotating member (200). The operating member (500) can be inserted into the interior of the housing (100) through the through-hole (140) of the housing (100) and connected to the rotating member (200), and when connected to the rotating member (200), it can be rotated together with the rotating member (200) to change the position of the locking member (300).

[0070] These operating members (500) can be operated directly by the user or can be operated automatically by a separate device.

[0071] For example, the operating member (500) may be composed of an operating part (500a) and a gripping part (500b), as illustrated in FIGS. 2 and 3. This is an example of the operating member (500) being directly operated by a worker. The operating part (500a) is a part that is inserted into the through part (140) of the housing (100) and connected to the rotating member (200), and the gripping part (500b) is a part that can be directly operated by a worker while connected to the operating part (500a). These operating part (500a) and gripping part (500b) may be configured to be separable from each other, thereby ensuring portability and work convenience.

[0072] Meanwhile, as illustrated in FIG. 4, the rotational shaft portion (130) may have a second support portion (132) formed extending from the center of the first support portion (131) toward the penetration portion (140), and the rotational member (200) may have a second insertion portion (230) formed by penetrating axially from the center of the first insertion portion (220) to insert the second support portion (132) and the operating member (500).

[0073] Here, the operating member (500) is formed in a cylindrical shape having a hollow end that is inserted into the penetration part (140), and when inserted into the penetration part (140), a second support member (132) can be inserted into the inside of the hollow.

[0074] Thus, the second support member (132) is extended from the center of the first support member (131) to be inserted into the second insertion part (230) of the rotating member (200), thereby allowing the operating member (500) inserted through the through-hole (140) of the housing (100) to be connected to the second support member (132). Additionally, in the case of the operating member (500), the end inserted into the through-hole (140) is formed to have a hollow, so that the second support member (132) is inserted into the hollow of the operating member (500), making it easy to match and connect the operating member (500) to the rotating member (200).

[0075] To this end, the outer diameter of the end inserted into the penetration portion (140) in the operating member (500) may be formed to match the second insertion portion (230) of the rotating member (200), and the inner diameter of the hollow may be formed to match the outer diameter of the second support portion (132).

[0076] Meanwhile, the rotating member (200) may have at least one projection (231) protruding from the inner circumference of the second insertion part (230), and the operating member (500) may have at least one slit (510) into which the projection (231) is inserted when inserted into the through part (140).

[0077] The second insertion part (230) of the rotating member (200) is penetrated so that the operating member (500) is inserted, and at least one projection part (231) protrudes from the inner circumference, and the projection part (231) can be extended in the axial direction of the rotating member (200).

[0078] In the operating member (500), a slit (510) may be formed that matches the protrusion (231) and into which the protrusion (231) is inserted, and may be formed to extend in the longitudinal direction so that the protrusion (231) extending in a straight line can be inserted.

[0079] The protrusions (231) and slits (510) can be formed in equal numbers, and if formed in multiple numbers, they can be arranged with equal spacing.

[0080] Through this, when the operating member (500) is inserted into the through-hole (140) of the housing (100), the end of the operating member (500) is inserted between the second insertion part (230) of the rotating member (200) and the second support part (132) of the rotation shaft part (130), and the protrusion part (231) of the rotating member (200) is inserted into the slit (510) of the operating member (500), thereby connecting the rotating member (200) and the operating member (500), so that the operating member (500) can be operated to rotate the rotating member (200). As a result, the locking portion (210) of the rotating member (200) may come into contact with the locking member (300), thereby allowing the locking member (300) to restrain the fixing jig (600) or allow the locking member (300) to detach from the fixing jig (600).

[0081] Meanwhile, in the present disclosure, the locking portion (210) of the rotating member (200) is formed to have an inclined surface in one direction, so that when the locking member (300) contacts it, rotation is allowed in the direction in which the inclined surface is formed, and rotation is restricted in the opposite direction by being caught on the locking member (300).

[0082] The locking portion (210) may be formed in the shape of a gear with an inclined surface formed in only one direction, and a ledge is formed on the opposite side of the part where the inclined surface is formed, so that when the rotating member (200) rotates, the locking member (300) can pass over the inclined surface to allow rotation, and the locking member (300) can be locked on the opposite side of the inclined surface to restrict rotation. Through this, the present disclosure can set the locking direction or unlocking direction of the housing (100) and the fixing jig (600) to a specific direction.

[0083] Meanwhile, referring to FIGS. 3 and FIGS. 7, the locking member (300) may be composed of a holder part (310), a body part (320), and a contact part (330).

[0084] Here, the body portion (320) is provided to be movable inside the housing (100), and the holder portion (310) is formed to extend to one side of the body portion (320) and be exposed to the outside of the housing (100) so that a fixing jig (600) can be fastened, and the contact portion (330) is formed to extend from the body portion (320) to the other side so as to be in contact with a rotating member (200).

[0085] The holder part (310), body part (320), and contact part (330) can be formed as a single unit.

[0086] The body portion (320) may be arranged to move in a straight line within the second space (120) of the housing (100). Accordingly, the second space (120) of the housing (100) may be formed in an angular shape, and the body portion (320) may also be formed in an angular shape to match the shape of the second space (120). Additionally, a support member (400) is connected to the body portion (320), and the support member (400) can elastically support the body portion (320) within the housing (100) and provide elastic force in the direction in which the body portion (320) faces the rotating member (200).

[0087] The holder portion (310) extends to one side of the body portion (320) and is exposed to the outside of the housing (100) so that the fixing jig (600) can be fastened. Additionally, the holder portion (310) can be formed to allow the fixing jig (600) to be fastened. To this end, the holder portion (310) may have a through hole portion (311) formed therein to allow the fixing jig (600) to pass through. That is, when the fixing jig (600) is inserted through the hole portion (311) of the holder portion (310) and the holder portion (310) moves in the direction of being inserted into the housing (100), the fixing jig (600) can be restrained.

[0088] In detail, the fixing jig (600) is formed in a bar shape and has a fastening hole (610) formed therein, and the holder part (310) is formed so that the fixing jig (600) can be inserted into the hole part (311), and a fastening part (312) that can be inserted into the fastening hole (610) of the locking member (300) can be formed in the hole part (311).

[0089] Here, the fastening hole (610) of the fixing jig (600) and the fastening part (312) of the holder part (310) are formed in the same shape so that no gap occurs when fastening.

[0090] Referring to FIGS. 5 and 6, the fixing jig (600) is formed in a bar shape so that it can be inserted into the hole portion (311) of the holder portion (310). When the locking member (300) moves to be inserted into the housing (100) while the fastening portion (312) formed in the hole portion (311) of the holder portion (310) is matched to the fastening hole (610) of the fixing jig (600), the fixing jig (600) can be restrained by inserting the fastening portion (312) into the fastening hole (610). As a result, the fixing jig (600) can be maintained in a fixed state when fastened to the locking member (300).

[0091] Meanwhile, referring to FIG. 8, the locking portion (210) of the rotating member (200) is formed to have an inclined surface in one direction, and the contact portion (330) can be formed to have an inclined surface that matches the inclined surface of the locking portion (210).

[0092] As a result, the rotating member (200) is allowed to rotate in the direction in which the inclined surface is formed, and rotation may be restricted in the opposite direction by contacting the contact portion (330). In particular, the inclined surface of the locking portion (210) is formed such that the direction of the inclined surface matches the direction of the inclined surface of the part of the contact portion (330) that contacts the locking portion (210), thereby allowing the locking portion (210) to move smoothly along the inclined surface when the rotating member (200) rotates, and when the rotating member (200) rotates in the opposite direction of the inclined surface, the locking portion (210) and the contact portion (330) can be engaged.

[0093] Through this, when the rotating member (200) is rotated using the operating member (500) while the fixed jig (600) is restrained to the locking member (300) as shown in FIG. 7, the locking member (300) can be pulled out to the outside of the housing (100) by being pushed by the catch portion (210) of the rotating member (200) as shown in FIG. 8. At this time, the locking member (300) compresses the support member (400), and the fixed jig (600) can be detached from the locking member (300).

[0094] Afterwards, when the fixed jig (600) is to be re-secured to the housing (100), the fixed jig (600) is inserted into the hole (311) of the locking member (300) as shown in FIG. 9. At this time, the rotating member (200) ensures that the locking part (210) is in contact with the locking member (300) by the operating member (500).

[0095] Here, as illustrated in FIG. 10, when the rotating member (200) is further rotated using the operating member (500), the locking member (300) is disengaged from the catch (210) and moved to be drawn into the inside of the housing (100) by the elastic force of the supporting member (400), and the fixing jig (600) can be restrained by the locking member (300) by inserting the fastening part (312) of the locking member (300) into the fastening hole (610) of the fixing jig (600).

[0097] According to the docking device of the present disclosure, convenience for assembling or separating a plurality of modules is ensured, and fastening force is ensured when assembling the modules.

[0099] Although specific embodiments of the present disclosure have been illustrated and described, it is obvious to those skilled in the art that the present disclosure may be modified and changed in various ways without departing from the technical spirit of the present disclosure as provided by the following claims.
