Description

Hydraulic cable disconnecter

[0001] An embodiment of the present invention relates to a hydraulic cable separation device, and more specifically, to a device capable of separating and connecting hydraulic cables of machinery that are separated into two parts.

[0002] Hydraulic cables are widely used in various types of hydraulically operated machinery. For example, hydraulic cables are used in diverse fields such as hydraulic excavators, hydraulic bulldozers, and hydraulic brakes.

[0003] To disassemble or repair parts containing hydraulic cables, it is necessary to disconnect the cables. Generally, hydraulic couplers are used to connect and disconnect hydraulic cables. For example, in hydraulic excavators, hydraulic couplers can be used to connect the hydraulic cable of a hydraulically operated part or accessory to the hydraulic cable of the main body, enabling the replacement or disassembly of the part or accessory.

[0004] A typical hydraulic coupler consists of a pair of male and female connectors connected to each hydraulic cable. To connect a hydraulic coupler, the male connector must be pushed into the female connector and secured by twisting it, or secured with a separate pin. Difficulties exist in connecting or disconnecting hydraulic couplers when they are located inside machinery, where the workspace is cramped or visibility is poor.

[0005] The technical problem that the embodiment of the present invention aims to solve is to provide a hydraulic cable separation device that facilitates the separation or connection of hydraulic cables present in machinery separated into two parts.

[0006] An example of a hydraulic cable separation device according to an embodiment of the present invention for achieving the above technical problem comprises: a front part including a forward moving part formed to enable movement in the forward and backward directions; a rear part including a rear moving part formed to enable movement in the forward and backward directions; a first coupling part located behind the front moving part; a second coupling part located in front of the rear moving part and capable of coupling with the first coupling part; and a hydraulic coupler including a first connector and a second connector, respectively connected to a first hydraulic cable and a second hydraulic cable, wherein the first connector and the second connector of the hydraulic coupler are respectively located in the front part and the rear part so as to be aligned on the same axis when the first coupling part and the second coupling part are coupled, and either the first connector or the second connector is fixed to the front moving part or the rear moving part, and when the front moving part and the rear moving part move together after being coupled through the first coupling part and the second coupling part, the first connector and the second connector are connected.

[0007] According to an embodiment of the present invention, the separation or connection of hydraulic cables present in machinery separated into two parts can be facilitated.

[0016] Hereinafter, a hydraulic cable separation device according to an embodiment of the present invention will be examined in detail with reference to the attached drawings.

[0017] FIG. 1 is a drawing showing the overall shape of an embodiment of a hydraulic cable separation device according to an embodiment of the present invention, FIG. 2 is a drawing showing an exploded perspective view of the front part of a hydraulic cable separation device according to an embodiment of the present invention, and FIG. 3 is a drawing showing an exploded perspective view of the rear part of a hydraulic cable separation device according to an embodiment of the present invention.

[0018] Referring to FIGS. 1 to 3 together, the hydraulic cable separation device (100) largely comprises a front section (110) and a rear section (150). The front section (110) includes a front moving section (200), a first coupling section (220), and a first connector (240-1) of a hydraulic coupler connected to a first hydraulic cable (280). The rear section (150) includes a rear moving section (300), a second coupling section (320), and a second connector (240-2) of a hydraulic coupler connected to a second hydraulic cable (350).

[0019] The front moving part (200) is formed in the front part (110) to enable movement in the front and rear directions, and the rear moving part (300) is formed in the rear part (150) to enable movement in the front and rear directions. The first connecting part (220) is formed on one side (e.g., the rear) of the front moving part (200), and the second connecting part (320) is formed on one side (e.g., the front) of the rear moving part (300).

[0020] The structure for the forward movement of the forward movement unit (200) in the forward and backward directions can be implemented in various forms. In one embodiment, the forward unit (110) may include a forward fixing unit (210) that includes a first guide means (not shown) for linear movement in the forward and backward directions. The forward movement unit (200) is connected to the forward fixing unit (210) so that it can move linearly in the forward and backward directions along the first guide means. For example, the first guide means may be formed in a structure that includes a rail-shaped groove on the inner side of the forward fixing unit (210) so as to correspond to a rail-shaped protrusion (212) formed in the longitudinal direction on one side of the forward movement unit (200). In addition to this, various structures that enable the forward movement unit (200) to move linearly relative to the forward fixing unit (210) may be applied to this embodiment and are not limited to a specific structure. In another embodiment, the forward movement unit (200) may be implemented to enable movement along a curved trajectory in the forward and backward directions. To this end, the forward fixing part (210) may include a guide means for curved trajectory movement. However, for the convenience of explanation, the following description assumes that the forward moving part (200) moves in a straight line in the forward and backward directions.

[0021] The structure for the movement of the rear moving part (300) in the forward and backward directions can be implemented in various forms. In one embodiment, the rear part (150) may include a rear fixed part (310) that includes a second guide means (312) for linear movement in the forward and backward directions. The rear moving part (300) is connected to the rear fixed part (310) so that it can move linearly in the forward and backward directions along the second guide means (312). For example, the second guide means (312) may be formed in the shape of a rail, and the rear moving part (300) may be connected to the second guide means (312) in a manner that fits into the rail, thereby enabling reciprocating linear movement along the rail. In addition to this, various structures in which the rear moving part (300) can move linearly relative to the rear fixed part (310) may be applied to this embodiment, and are not limited to a specific structure. In another embodiment, the rear moving part (300) may be implemented to enable movement along a curved trajectory in the forward and backward directions. To this end, the rear fixing part (310) may include a guide means for curved trajectory movement. However, for the convenience of explanation, the following description assumes that the rear moving part (300) moves in a straight line in the forward and backward directions.

[0022] In another embodiment, an elastic material (314) may be further included to apply force to the rear moving part (300) so that the rear moving part (300) moves backward along the second guide means (312) to facilitate separation between the forward moving part (200) and the rear moving part (300). In this embodiment, a spring located in the second guide means (312) is illustrated as an example of the elastic material (314), but this is only one example, and various elastic materials other than a spring may be used. Additionally, the elastic material (314) may be omitted depending on the embodiment.

[0023] The forward movement part (200) and the rear movement part (300) are connected to each other through the first coupling part (220) and the second coupling part (320). This embodiment illustrates an example of a locking coupling using the first coupling part (220) and the second coupling part (320), but this is merely one example, and various types of conventional coupling structures, such as screw coupling or insertion coupling, may be used, and are not limited to this embodiment. For example, the first coupling part (220) may be formed as a tactile projection, and the second coupling part (320) may include a latch. In addition, the first coupling part (220) and the second coupling part (320) may be implemented in various shapes, which will be examined again in FIGS. 9 and FIGS. 10. However, for convenience of explanation, the following description will focus on the locking coupling structure.

[0024] The hydraulic coupler includes a first connector (240-1) and a second connector (240-2). The structure of the first connector (240-1) and the second connector (240-2) included in the hydraulic coupler can be varied in many ways. In one embodiment, when using a hydraulic coupler that includes male and female connectors, the first connector (240-1) may be a female connector and the second connector (240-2) may be a male connector, or conversely, the first connector (240-1) may be a male connector and the second connector (240-2) may be a female connector. However, for convenience of explanation, the following description assumes the case where the first connector (240-1) is a male connector and the second connector (240-2) is a female connector. Furthermore, although this embodiment illustrates a single hydraulic coupler, this is merely for convenience of explanation, and multiple hydraulic couplers may exist in parallel.

[0025] The first connector (240-1) is located at the front part (110) and connected to the first hydraulic cable (280), and the second connector (240-2) is located at the rear part (150) and connected to the second hydraulic cable (350). Generally, when connecting the first connector (240-1) and the second connector (240-2), the hydraulic coupler must push the second connector (240-2) into the first connector (240-1) so that the oil does not leak out and the connection is perfectly sealed. However, if the hydraulic coupler is located in a narrow space of machinery or in a dark environment where the hydraulic coupler is not easily visible, it is difficult to connect and secure the first connector (240-1) and the second connector (240-2).

[0026] To solve these problems, the present embodiment utilizes the coupling and movement between the forward moving part (200) and the rear moving part (300) as a method of connecting the first connector (240-1) and the second connector (240-2). When the forward moving part (200) and the rear moving part (300) are coupled to each other through the first coupling part (220) and the second coupling part (320), the first connector (240-1) and the second connector (240-2) are positioned at the front part (110) and the rear part (150), respectively, so that the first connector (240-1) and the second connector (240-2) are aligned on the same axis. In addition, one of the first connector (240-1) and the second connector (240-2) is fixed to the front moving part (200) or the rear moving part (300) so that when the front moving part (200) and the rear moving part (300) move in a straight line after being combined with each other, the first connector (240-1) and the second connector (240-2) can be automatically connected.

[0027] In the first embodiment, the second connector (240-2) is fixed to the rear moving part (300), and the first connector (240-1) may be fixed to one side of the front part (110) (or front fixed part (210)) rather than the front moving part (200). In this case, the second connector (240-2) moves together when the rear moving part (300) moves in a straight line in the forward and backward directions, and the first connector (240-1) is fixed in position and is not affected by the movement of the front moving part (200) or the rear moving part (300). When the front moving part (200) and the rear moving part (300) move together forward after being connected to each other through the first coupling part (220) and the second coupling part (320), the second connector (240-2) moves and connects to the first connector (240-1).

[0028] In a second embodiment, the first connector (240-1) is fixed to the forward moving part (200), and the second connector (240-2) may be fixed to one side of the rear part (150) (or rear fixed part (310)) rather than the rear moving part (300). In this case, when the forward moving part (200) and the rear moving part (300) move to the rear after being connected to each other through the first and second connecting parts (320), the first connector (240-1) moves and connects to the second connector (240-2).

[0029] In a third embodiment, to strengthen the close contact between the first connector (240-1) and the second connector (240-2), the first connector (240-1) may be fixed to a connector moving part (230) located in the front part (110), and the second connector (240-2) may be fixed to a rear moving part (300). The connector moving part (230) is formed in the front part (110) to enable movement in the front and rear directions.

[0030] For example, the front portion (110) may include a front fixing portion (210) comprising a third guide means (202) for linear movement in the front-rear direction, a connector moving portion (230) connected to the front fixing portion (210) to enable linear movement in the front-rear direction along the third guide means (202) and fixing a first connector (240-1) on one side, and an elastic material (204) that applies a rearward force to the connector moving portion (230) so that the connector moving portion (230) moves rearward along the third guide means (202). The third guide means (202) is formed in a rail shape, and the connector moving portion (230) is connected to the third guide means (202) in a manner that fits into the rail to enable linear movement. The third guide means (202) is not limited to a rail shape and may be formed in various structures that enable linear movement of the connector moving portion (230). In another embodiment, the connector moving part (230) may be implemented to enable movement along a curved trajectory in the forward and backward directions. To this end, the forward fixing part (210) may include a third guide means for movement along a curved trajectory. However, for convenience of explanation, the following description assumes that the connector moving part (230) moves in a straight line in the forward and backward directions.

[0031] According to the third embodiment, when the forward moving part (200) and the rear moving part (300) are combined and move forward together, the second connector (240-2) moves forward, and a force is applied backward to the connector moving part (230) by the elastic material (204) located in the third guide means (202). Therefore, the first connector (240-1) receiving the force applied backward and the second connector (240-2) moving forward can be more strongly in contact with each other.

[0032] FIGS. 1 to 3 illustrate a third embodiment, but this is merely one example, and the hydraulic cable separation device (100) may be implemented as a first embodiment or a second embodiment. For convenience of explanation, the following description assumes that the hydraulic cable separation device (100) is implemented as a third embodiment.

[0033] After combining the forward moving part (200) and the rear moving part (300), the user can move the forward moving part (200) or the rear moving part (300) by holding it directly. However, if the space where the hydraulic cable separation device (100) is installed is narrow, it is inconvenient for the user to move the forward moving part (200) and the rear moving part (300) by holding them directly with their hands.

[0034] Accordingly, the present embodiment may further include a structure to facilitate linear movement of the combined forward moving part (200) and the rear moving part (300). For example, the hydraulic cable separation device (100) may further include a lever (250) connected to one side of the front part (110) via a rotational axis, and a motion conversion part that converts the rotational motion of the lever (250) into linear motion and transmits it to the forward moving part (200). The lever (250) may be connected to one side of the front fixed part (210) via a rotational axis, or, as shown in FIG. 4, connected to one side of the front frame (400) of the machinery on which the front part (110) is installed via a rotational axis. For convenience of explanation, the present embodiment assumes the case where the lever (250) is installed on the front frame (400).

[0035] The motion conversion unit that converts the rotational motion of the lever (250) into linear motion can be formed in various structures. The motion conversion unit can be formed in various structures, such as a gear structure or a cam structure. As an example of an embodiment, we examine the case where the motion conversion unit is implemented as a cam structure. The motion conversion unit may include a cam plate constituting the lever (250), an arc-shaped groove (252) formed in the cam plate, and a body part (260) that protrudes from one side of the forward moving part (200) and is fitted into the arc-shaped groove (252). When the lever (250) rotates along the rotation axis (256), the rotational motion is converted into linear motion by the body part (260) fitted into the groove (252) and transmitted to the forward moving part (200). When the lever (250) rotates downward (i.e., clockwise), the forward moving part (200) moves forward, and conversely, when the lever (250) rotates upward along the rotation axis (256) (i.e. counterclockwise), the forward moving part (200) moves backward. This embodiment illustrates an example in which the lever (250) and the motion conversion part are implemented in the front part (110), but in other embodiments, the lever (250) and the motion conversion part may be implemented in the rear part (150). When the lever (250) and the motion conversion part are installed in the rear part (150), the rotational movement of the lever (250) is transmitted as linear movement of the rear moving part (300). However, for convenience of explanation, the following description assumes the case where the lever (250) and the motion conversion part are implemented in the front part (110). Also, in other embodiments, the lever (250) and the motion conversion part may be omitted. In another embodiment, a rotation axis spring may be further included in the rotation axis (256) of the lever so that the lever can automatically rise in an upward direction (counterclockwise).

[0036] After connecting the first connector (240-1) and the second connector (240-2) by combining and moving the forward moving part (200) and the rear moving part (300), the hydraulic coupler can be fixed by a conventional method such as a fixing pin, or the two connectors (240-1, 240-2) can be fixed by twisting them together. To eliminate the inconvenience of fixing the hydraulic coupler using a fixing pin, etc., a fixing means capable of fixing the position of the forward moving part (200) and the rear moving part (300) may be further included.

[0037] When the first connector (240-1) and the second connector (240-2) of the hydraulic coupler are connected by the combination and movement of the forward movement part (200) and the rear movement part (300), the positions of the forward movement part (200) and the rear movement part (300) can be fixed using a fixing means so that the first connector (240-1) and the second connector (240-2) do not come apart from each other. The fixing means can be implemented in various forms.

[0038] In one embodiment, when a lever (250) that transmits linear motion force to a forward moving part (200) is present, a lever fixing part may be included as a fixing means. The lever fixing part includes a fixing groove (254) formed in a cam plate constituting the lever (250) and a pressing pin (270) located in the forward fixing part (210) to be inserted into or separated from the fixing groove (254). The pressing pin (270) may be located at a position corresponding to the fixing groove (254) when the lever (250) is lowered downward.

[0039] When the fixed groove (254) moves to the position of the push pin (270) by the rotation of the lever (250), the push pin (270) is inserted into the fixed groove (254) to fix the rotation of the lever (250). The push pin (270) may include a protrusion (274) having a size corresponding to the fixed groove (254) and a spring (272) at the lower part thereof. When the push pin (270) is pressed, the protrusion (274) is released from the fixed groove (254) so ​​that the lever (250) becomes rotatable, and when the fixed groove (254) of the lever (250) comes to the position of the push pin (270), the pressed push pin (270) pops out by the spring (272), and the protrusion (274) is inserted into the fixed groove (254) to fix the current position of the lever. In addition to this, the lever fixing part for fixing the rotation of the lever can be modified into various structures and is not limited to this embodiment.

[0040] In order to separate the first connector (240-1) and the second connector (240-2) of the hydraulic coupler, separation between the forward moving part (200) and the rear moving part (300) is required. Although the user can directly separate the first coupling part (220) and the second coupling part (320) by grasping them, separation may be difficult if the space is narrow or dark.

[0041] Accordingly, to facilitate the separation of the first coupling part (220) and the second coupling part (320) connecting the forward moving part (200) and the rear moving part (300), a separation means (330) may be further included to move at least one of the first coupling part (220) and the second coupling part (320) in the coupling separation direction. The coupling separation method and coupling separation direction of the first coupling part (230) and the second coupling part (320) for releasing the coupling according to the coupling method of the first coupling part (230) and the second coupling part (320) are different. For example, the first coupling part (230) and the second coupling part (320) may be implemented in a structure in which they are coupled by interlocking male and female parts, and the internal male and female coupling is released by pressing a release button. In this case, the separation means (330) may be a structure related to the pressing of the button. As another example, when the first coupling part (220) and the second coupling part (320) are in a locking coupling, a separation means (330) for moving at least one of the first coupling part (220) and the second coupling part (320) in any one of the up, down, left, or right directions to release the locking coupling may be further included. However, for convenience of explanation, the following description assumes that the first coupling part (220) and the second coupling part (320) are in a locking coupling in the up and down direction. Depending on the embodiment, the separation means (330) may be omitted.

[0042] In one embodiment, the separation means (330) may include a rotational connection part (332) connected to the rear part (150) (or rear fixed part (310)) as a rotation axis, and an elastic material (334) that applies force to the rear part (150) (or rear fixed part (310)) so that the front end of the rear moving part (300) where the second coupling part (320) is located moves downward. The elastic material (334) may be implemented as a spring located around the rotational connection part (332). In addition to this, various other structures of separation means may be implemented. The structures of other separation means will be examined again in FIGS. 11 to 20.

[0043] FIGS. 4 to 8 are drawings illustrating an example of the operation process of a hydraulic cable separation device according to an embodiment of the present invention.

[0044] This embodiment illustrates a case where a hydraulic cable separation device (100) is installed in machinery in which the front frame (400) and the rear frame (410) are separated. The front frame (400) and the rear frame (410) are part of various types of machinery and are not limited to specific examples.

[0045] Referring to FIG. 4, the front part (110) of the hydraulic cable separation device (100) is installed on the front frame (400), and the rear part (150) is installed on the rear frame (410). This embodiment illustrates an example in which the front frame (400) and the rear frame (410) are connected by a 'C'-shaped connection structure (402, 412), but this is for convenience of explanation only, and the structure of the front frame (400) and the rear frame (410) is unrelated to the hydraulic cable separation device (100) of this embodiment. The connection of the front frame (400) and the rear frame (410) can be performed manually or automatically.

[0046] The lever (250) may further include a frame connection groove (420) for connecting and fixing the front frame (400) and the rear frame (410). The frame connection groove (420) of the lever (250) is an additional configuration depending on the structure of the front frame (400) and the rear frame (410), and if the type of machinery on which the hydraulic cable separation device (100) is installed changes, the frame connection groove (420) may be omitted or modified into a different structure.

[0047] Referring to FIGS. 5 and 6, when the front frame (400) and the rear frame (410) are combined, the first coupling part (220) located in the front moving part (200) and the second coupling part (320) located in the rear moving part (300) move to the combined position. In one embodiment, the first coupling part (220) and the second coupling part (320) may be aligned on the same axis so that the first coupling part (220) and the second coupling part (320) are automatically coupled when the front frame (400) and the rear frame (410) are combined.

[0048] In the case of the present embodiment, the front frame (400) and the rear frame (410) are formed with a 'C'-shaped coupling structure (402, 412), and the first coupling part (220) and the second coupling part (320) are a locking coupling structure using a protrusion. Therefore, when the front frame (400) and the rear frame (410) are close to each other, as shown in FIG. 5, the first coupling part (220) presses the second coupling part (320) from top to bottom (500). That is, when the front frame (400) and the rear frame (410) are close to each other, the second coupling part (320) presses the first coupling part (220) from top to bottom. This embodiment illustrates a case where the first coupling part (220) is located above the second coupling part (320), but this is merely one example, and the relative position between the first coupling part (220) and the second coupling part (320) (e.g., up, down, left, right, etc.) can be varied according to the embodiment. However, for convenience of explanation, the following description assumes the case where the first coupling part (220) is located above the second coupling part (320).

[0049] If there is no elasticity at all that allows the first coupling part (220) (or forward moving part (200)) and the second coupling part (320) (or rear moving part (300)) to move up and down, the second coupling part (320) will not move down at all, and as a result, a situation may occur where the first coupling part (220) gets caught on the second coupling part (320) and cannot be coupled to each other.

[0050] As an example of a method to solve this, the separation means (330) examined in the embodiments of FIGS. 1 to 3 may be used. For example, through the rotational connection part (332) and the elastic material (334) of the separation means (330) present in the rear part (150), the second coupling part (320) has elasticity that allows it to move a certain distance in the vertical direction. Therefore, as shown in FIG. 6, the first coupling part (220) can pass over the protrusion of the second coupling part (320) and be joined to each other (600). In this embodiment, the need for vertical elasticity in the second coupling part (320) is due to the structure of the front frame (400) and the rear frame (410) on which the hydraulic cable separation device (100) is installed. If the front frame (400) and the rear frame (410) are in an inverted 'U'-shaped joint structure rather than a 'C'-shaped joint structure, the first joint part (220) comes down from the top to the bottom and is joined to the second joint part (320), so a separation means (330) may not be necessary.

[0051] Referring to FIG. 7, when the lever (250) rotates downward (i.e. clockwise) after the first coupling part (220) and the second coupling part (320) are coupled, the forward moving part (200) moves forward. The rear moving part (300) coupled with the forward moving part (200) also moves forward together, and as a result, the second connector (240-2) of the hydraulic coupler located on the rear moving part (300) is connected to the first connector (240-1) (700). The current position of the lever (250) is fixed through the push pin (270) of the lever (250).

[0052] Referring to FIG. 8, the separation process of the first connector (240-1) and the second connector (240-2) of the hydraulic coupler is illustrated. In order to separate the first connector (240-1) and the second connector (240-2), separation between the forward moving part (200) and the rear moving part (300) is required. First, when the lever (250) is raised, the forward moving part (200) and the rear moving part (300) move together to the rear, resulting in a state as shown in FIG. 6. In other words, since the rear moving part (300) receives a force in the rear by the elastic material (314) located on the second guide means (312) of the rear fixing part (310), when the lever (250) is raised, the forward moving part (200) and the rear moving part (300) move together to the rear. Subsequently, to separate the connection between the first connecting part (220) of the forward moving part (200) and the second connecting part (320) of the rear moving part (300), a separation handle (800) located on one side of the rear part (150) is pulled. When the separation handle (800) is pulled, the front of the rear moving part (300) moves downward through the rotating connecting part (332) of the separation means (330) as shown in FIG. 5, and as a result, the connection between the second connecting part (320) located in the rear moving part (300) and the first connecting part (220) located in the forward moving part (200) is separated. In another embodiment, a separation means that does not require a separation handle (800) can be implemented, and this is examined in FIG. 11 to FIG. 20.

[0053] FIGS. 9 and FIGS. 10 are drawings illustrating other embodiments of the first and second coupling parts (320) of a hydraulic cable separation device (100) according to an embodiment of the present invention.

[0054] Referring to FIG. 9, the overall shape and cross-sectional structure before and after the connection of the first connecting part (900) of the forward moving part (200) and the second connecting part (910) of the rear moving part (300) are illustrated. The first connecting part (900) has an open lower portion and includes an arched protrusion extending from the top downward. The second connecting part (910) includes a circular protrusion. The arched protrusion of the first connecting part (900) is engaged with the circular protrusion of the second connecting part (910). In another embodiment, the first connecting part (900) may have an open upper portion and include an arched protrusion extending from the bottom upward. In yet another embodiment, the shape of the first connecting part (900) and the shape of the second connecting part (810) may be implemented in the opposite way to the present embodiment.

[0055] Referring to FIG. 10, the first coupling part (1000) of the forward moving part (200) has an open lower portion as in FIG. 9 and includes a projection formed from top to bottom. The second coupling part (1010) includes a concave portion corresponding to the projection of the first coupling part (1000). The projection of the first coupling part (1000) is engaged with the concave portion of the second coupling part (1010). In another embodiment, the first coupling part (1000) may have an open upper portion and include an arch-shaped protrusion from bottom to top. In yet another embodiment, the shape of the first coupling part (1000) and the shape of the second coupling part (1010) may be implemented in the opposite way to the present embodiment.

[0056] FIGS. 9 and FIGS. 10 are merely examples to illustrate that the first coupling part (220) of the forward moving part (200) and the second coupling part (320) of the rear moving part (300) can be deformed into various shapes. In addition to this, various coupling structures for coupling between the two parts may be applied to this embodiment.

[0057] FIGS. 11 to 16 are drawings illustrating other embodiments of the separation means of a hydraulic cable separation device according to an embodiment of the present invention.

[0058] FIG. 11 is a drawing showing the overall shape of a front part (110) including a separation means (1100), FIG. 12 is a drawing showing an example of a separated perspective view of a front part (110) including a separation means (1100), FIG. 13 and FIG. 14 are drawings showing the operating principle of a first coupling part (220) including a separation means (1100), and FIG. 15 and FIG. 16 are drawings showing the coupling and separation process of the first coupling part (220) and the second coupling part (320) using the separation means (1100).

[0059] Referring to FIGS. 11 and 12, the separation means (1100) includes a rotational connection part that connects the forward moving part (200) and the first coupling part (220) via a rotational axis, and a rotational axis spring (not shown) located on the rotational axis to apply an upward rotational force (i.e., counterclockwise) to the first coupling part (220). Through the upward and downward movement of the first coupling part (220), the first coupling part (220) can be coupled to or separated from the second coupling part (320). The separation means (1100) connects the head portion of the first coupling part (220) to the forward moving part (220) through the rotational connection part.

[0060] Referring to FIGS. 13 and 14, the first coupling part (220) can be implemented to automatically move up and down according to the forward and backward movement of the forward movement part (200). For example, when the forward movement part (200) moves forward, the first coupling part (220) moves downward as shown in FIG. 14, and when the forward movement part (200) moves backward, the first coupling part (220) can move upward as shown in FIG. 13. To this end, a step area (1300, 1400) that contacts the separation means (1100) exists at the rear end of the front fixing part (210).

[0061] The second step area (1400) at the rear end of the front fixing part (210) protrudes further downward than the first step area (1300). When the first coupling part (220) is located below the first step area (1300) (i.e., when the front moving part (200) is pushed backward as in FIG. 13), the first coupling part (220) exists in a state raised upward by the rotation axis spring of the separation means (1100). When the front moving part (200) moves forward, the first coupling part (220) moves to the lower side of the second step area (1400) of the front fixing part (210), and the head portion of the first coupling part (220) (i.e., the separation means (1100)) is pressed down by the second step area (1400) and comes down downward.

[0062] Referring to FIGS. 15 and 16, when the front frame (400) and the rear frame (410) are combined, the first connecting part (220) is in a state where it is raised upward as in FIG. 13 through the separation means (1100), so the first connecting part (220) can move to the position of the locking connection without getting caught on the protrusion of the second connecting part (320). After the front frame (400) and the rear frame (410) are combined, when the lever (250) is pressed downward (i.e. clockwise) (A), the front moving part (200) moves straight forward, and as a result, the first connecting part (220) located on the front moving part (200) rotates downward by the second step area (1400) of the front fixing part (210) and connects with the second connecting part (320). Conversely, when the lever (250) rotates upward (i.e., counterclockwise), the forward moving part (200) moves backward. As a result, the first coupling part (220) located on the forward moving part (200) is positioned below the first step area (1300) of the front fixing part (210), lifted upward, and automatically separated from the second coupling part (320). Therefore, the separation handle (800) of FIG. 8 is not required in this embodiment.

[0063] FIGS. 17 to 20 are drawings illustrating another embodiment of a separation means of a hydraulic cable separation device according to an embodiment of the present invention.

[0064] FIG. 17 is a drawing showing the overall shape of a front part (110) including a separation means, FIG. 18 is a drawing showing an example of a separated perspective view of a front part (110) including a separation means, FIG. 19 and FIG. 20 are drawings showing the process of joining and separating a first joining part (220) and a second joining part (320) using a separation means.

[0065] Referring to FIGS. 17 and 18, the separation means includes a rotary connecting part (1800) that connects the front part (110) to a rotation axis, and an elastic material (1700) located around the rotary connecting part (1800) to apply an upward force to the rear end of the front part (110) where the first coupling part (220) is located. A spring may be used as an example of the elastic material (1700).

[0066] In another embodiment, a spring (1810) may be further included between the lever (250) of the front part (110) and the front fixing part (210). The spring (1810) is fixed at one end to a hole (1820) on one side of the front fixing part (210) and at the other end to a hole (1830) on one side of the lever (250). When the lever (250) is pressed, the pressing force of the lever (250) is transmitted to the front fixing part (210) by the spring, and as a result, the rear end of the front fixing part (210) moves downward. Conversely, when the pressing force of the lever (250) is removed, the rear end of the front fixing part (210) moves upward.

[0067] In another embodiment, the spring (1810) can be implemented as a rotating shaft spring installed in the rotating connection part (1800), and the connection position of the spring (1810) can be varied according to the embodiment. In yet another embodiment, various means other than the spring (1810) can be applied to this embodiment so that the pressing force of the lever (250) is applied to the front fixing part (210).

[0068] Referring to FIGS. 19 and 20, the front portion (110) exists in a state where the front end is lowered relative to the rear end by means of a separation means including a rotational connection portion (1800) and an elastic material (1700). Accordingly, the first coupling portion (220) located at the rear end of the front portion (110) also exists in a state where it is raised together.

[0069] Since the rear end of the first coupling part (200) exists in an raised state, when the front frame (400) and the rear frame (410) are coupled, the first coupling part (220) can move to a position where it is engaged with the second coupling part (320) without being caught by the second coupling part (320). After the front frame (400) and the rear frame (410) are coupled, when the lever (250) is pressed downward, the rear end of the front part (110) receives downward force from the spring (1810) and moves down together. As a result, the first coupling part (220) and the second coupling part (320) are coupled to each other. When the lever (250) is rotated downward to the end, the front moving part (200) and the rear moving part (300) move forward together in a coupled state.

[0070] Conversely, when the lever (250) rotates upward, the rear end of the front part (110) moves upward by means of the elastic material (1700). As a result, the locking connection between the first connecting part (220) and the second connecting part (320) is released, and the rear moving part (300) moves backward. In this embodiment, since the first connecting part (220) and the second connecting part (320) are automatically separated when the lever (250) rotates upward (counterclockwise), the separation handle (800) of FIG. 8 is not required.

[0071] FIGS. 21 and 22 are drawings illustrating an example of a hydraulic cable separation device according to an embodiment of the present invention installed on a detachable bicycle.

[0072] Referring to FIGS. 21 and 22, the detachable bicycle (2100) includes a hydraulic brake. For the operation of the hydraulic brake, the hydraulic cable separation device (100) of the present embodiment is used to separate and connect a first hydraulic cable located on the front frame and a second hydraulic cable located on the rear frame. The front part (110) of the hydraulic cable separation device (100) is installed on the front frame (2200), and the rear part (150) is installed on the rear frame (2210).

[0073] The front frame (2200) and rear frame (2210) of the detachable bicycle (2100) include an upper frame connecting portion and a lower frame connecting portion. For example, the lower frame connecting portion of the front frame (2200) and the rear frame (2210) is connected by an inverted 'U'-shaped connecting portion. After connecting the lower frame connecting portion of the front frame (2200) and the rear frame (2210), the user can connect the upper frame connecting portion by rotating the front frame (2200) and the rear frame (2210) around the lower frame connecting portion.

[0074] After the lower frame connecting part and the upper frame connecting part are both connected, pressing the lever (250) downward (i.e., clockwise) automatically connects the forward moving part (200) and the rear moving part (300) of the hydraulic cable separation device (100). As a result, the forward moving part (200) and the rear moving part (300) move forward together, and the first connector (240-1) and the second connector (240-2) of the hydraulic coupler are automatically connected. Additionally, when the lever is lowered all the way, the lever is fixed by the lever fixing part.

[0075] When the user releases the lever (250), the lever (250) moves upward (counterclockwise rotation). When the lever (250) moves upward, the forward moving part (200) and the rear moving part (300) move backward, and as a result, the first connector (240-1) and the second connector (240-2) of the hydraulic coupler are automatically separated. Additionally, if the hydraulic cable separation device (100) includes the separation means described above, the first coupling part (220) and the second coupling part (320) can be separated through the separation means when the lever (250) moves upward.

[0076] This embodiment is intended only to explain an example of use of the hydraulic cable separation device (100), and the hydraulic cable separation device (100) can be installed in various types of machinery that require separation and connection of hydraulic cables, and is not limited to a specific type of detachable bicycle.

[0077] The present invention has been described above with reference to its preferred embodiments. Those skilled in the art will understand that the present invention may be embodied in modified forms without departing from the essential characteristics of the invention. Therefore, the disclosed embodiments should be considered in an illustrative rather than a restrictive sense. The scope of the invention is defined by the claims, not by the foregoing description, and all variations within the scope of the claims should be interpreted as being included in the invention.
