Description

Receptacle device with increased efficiency

[0001] The present invention relates to a receptacle device. More particularly, it relates to a receptacle device having increased efficiency in fastening and fuel injection.

[0002]

[0003] Receptacle devices for fuel injection are widely disclosed.

[0004] Figure 1 shows an example of a conventional receptacle device.

[0005] As shown in Fig. 1, in a conventional receptacle device (10), a male receptacle (10) and a female receptacle (12) are connected in a threaded manner (screw-fastening manner), and for this purpose, a user must manually perform the fastening using a male screw and a female screw (11-1, 12-1).

[0006] Such conventional receptacle devices (10) not only take a relatively long time to be manually fastened, but also have low usability and, in the case of receptacles for cryogenic fuels (e.g., liquefied hydrogen, etc.), there is also a risk of exposure to a cryogenic environment.

[0007] Additionally, the increase in the bonding time may cause additional problems such as fuel vaporization, especially when charging cryogenic fuel.

[0008] Therefore, a technical idea is required that can fasten the receptacle device quickly and easily, and also solve the safety problem that may arise from having to hold the screw for a relatively long time for screw fastening.

[0041]

[0042] The present invention is susceptible to various modifications and embodiments, and specific embodiments are illustrated and described in detail in the drawings. However, this is not intended to limit the present invention to specific embodiments, but rather to encompass all modifications, equivalents, and alternatives falling within the spirit and technical scope of the present invention. In describing the present invention, detailed descriptions of related known technologies will be omitted if they are deemed to obscure the gist of the present invention.

[0043] Terms such as first, second, etc. may be used to describe various components, but these components should not be limited by these terms. These terms are used solely to distinguish one component from another.

[0044] The terminology used in this application is solely for the purpose of describing specific embodiments and is not intended to limit the present invention. Singular expressions include plural expressions unless the context clearly dictates otherwise.

[0045] In this specification, terms such as “include” or “have” are intended to specify the presence of a feature, number, step, operation, component, part or combination thereof described in the specification, but should be understood not to exclude in advance the possibility of the presence or addition of one or more other features, numbers, steps, operations, components, parts or combinations thereof.

[0046] Hereinafter, the present invention will be described in detail, focusing on embodiments thereof, with reference to the attached drawings. The same reference numerals in each drawing represent the same components.

[0047] Figure 2 schematically illustrates the configuration of a receptacle device according to an embodiment of the present invention. Figure 3 is a drawing illustrating the specific configuration of a mail receptacle according to an embodiment of the present invention. In addition, Figure 4 is a drawing illustrating the fastening operation of a receptacle device according to an embodiment of the present invention.

[0048] Referring to FIGS. 2 to 4, a receptacle device (1) with increased efficiency according to an embodiment of the present invention includes a male receptacle (100) and a female receptacle (200).

[0049] The above-described mail receptacle (100) includes a lever (150) as illustrated in FIG. 2. The lever (150) may be configured to rotate longitudinally relative to the housing (130) of the mail receptacle (100). By the rotation of the lever (150), a predetermined component (e.g., a mail poppet valve (110) and a load part (120)) accommodated within the mail receptacle (100) may advance or retreat.

[0050] For example, the lever (50) can perform a rotation (e.g., counterclockwise rotation) to move the handle in the front direction, i.e., toward the front end of the male receptacle (100) (toward the female receptacle (200)), or a rotation (e.g., clockwise rotation) to move the handle in the rear direction, i.e., toward the rear end of the male receptacle (100), and accordingly, (e.g., the male poppet valve (110) and the load part (120)) can move forward or backward.

[0051] A user can insert a predetermined length of the front end of the male receptacle (100) into the female receptacle (200), and when the lever (150) is rotated in the front direction in this inserted state, the male poppet valve (110) moves forward and comes into contact with the female poppet valve (220) provided in the female receptacle (200), so that both the male poppet valve and the female poppet valve can be opened. It goes without saying that the length of the front end of the male receptacle (100) provided in the female receptacle (200) can be set in various ways depending on the implementation example.

[0052] When the lever (150) is rotated in a forward direction by a certain angle while the male receptacle (100) is inserted into the female receptacle (200) to the maximum, the male poppet valve (110) begins to contact the female poppet valve (220), and when the lever (150) is further rotated in this state, the male poppet valve (110) moves further forward, so that both the male poppet valve (110) and the female poppet valve (220) can be opened. Then, a predetermined amount of fuel can be moved from the male receptacle (100) to the female receptacle (200).

[0053] The above-described male receptacle (100) includes a first housing (130), a male poppet valve (110), a load part (120), and a lever (150). In addition, according to an implementation example, the male receptacle (100) may further include a poppet housing (140) that is connected to the front end of the first housing (130) and is formed to surround the front end of the male poppet valve (110). In addition, the male receptacle (100) may further include a hook part (160) for fastening with a female receptacle (200).

[0054] The first housing (130) can accommodate a load part (120) therein, and can be formed to include a space in which the load part (120) can move forward or backward according to the rotation of the lever (150).

[0055] According to an embodiment, the first housing (130) may be implemented to include a first outer housing (132) and a first inner housing (131). In addition, a vacuum space (V) may be formed between the first outer housing (132) and the first inner housing (131) to effectively block heat from the outside.

[0056] The load part (120) may have a cylindrical rod shape that can be moved forward or backward by the lever (150). A through hole may be formed inside the load part (120) to allow fuel to move, so that fuel can move inside the load part (120).

[0057] For example, the load part (120) may be implemented as a single rod, but depending on the embodiment, it may be implemented as a lever rod (122) whose movement is directly driven by the lever (150) and a body rod (121) connected to the front end of the lever rod (122). This is because, since the cryogenic fluid is introduced from the lever rod (122), it may be preferable for the lever rod (122) to be implemented with a material that can further reduce the freezing phenomenon, and the body rod (121) may not necessarily be made of such a material.

[0058] And the first internal housing (131) may also include a lever rod part (131-2) that accommodates the lever rod (122) and a body rod part (131-1) that accommodates the body rod (121). In addition, an extension part (131-3) that can accommodate a spring (113) of the male poppet valve (110) may be further formed at the front end of the first internal housing (131), and the spring (113) may be seated on a rear end step of the extension part (131-3).

[0059] The above mail poppet valve (110) is formed at the front end of the load part (120) and can move forward or backward in synchronization with the forward or backward movement of the load part (120).

[0060] The above mail poppet valve (110) includes a poppet tip (111) and a poppet body (112), and the poppet body (112) is connected to the lower end of the poppet body (112) to provide elastic force in the shear direction and can be connected to a spring (113) formed to surround the shear end of the load part (120).

[0061] The spring (113) wraps around the front end of the load part (120), and the rear end of the poppet body (112) can be connected to the front end of the spring (113). The spring (113) is accommodated in the expansion portion (131-3) formed in the front end of the first internal housing (131), and can be formed to be seated on the rear end step of the expansion portion (131-3) so as to restrict movement toward the rear end.

[0062] The above mail poppet valve (110) can be implemented as a 2-way valve that opens when a constant pressure is applied in the rear direction to the poppet tip (111). Since the structure and configuration of the poppet valve are widely known, a detailed description thereof will be omitted in this specification.

[0063] The front end of the first housing (130) may further include a poppet housing (140) that is connected to the front end (130) of the first housing and accommodates the male poppet valve (110) therein, and has a through hole formed at the front end through which the poppet tip of the male poppet valve (110) or female poppet valve (220) can pass.

[0064] The above poppet housing (140) is implemented to accommodate at least the poppet body (112), and may further accommodate a portion of the extension portion (131-3) of the first inner housing (131) according to an embodiment, and various embodiments are possible. The poppet housing (140) may be implemented with a material having excellent insulation performance when a cryogenic fluid such as liquefied hydrogen moves. This means that although a vacuum layer (vacuum separation space) for insulation is not formed at the bottom of the poppet housing (140), when connected to the female receptacle (120), boil-off can be reduced by having an insulation effect due to the vacuum layer formed in the female receptacle (120). Accordingly, the poppet housing (140) is implemented so that the front end has a narrower diameter than the rear end, and the vacuum layer of the female receptacle (120) can be formed to surround at least the poppet housing (140) when connected to the male receptacle (120) as shown in FIG. 5, and the vacuum layer can be formed longer in the direction of the load part (120).

[0065] The lever (150) is provided on the outside of the first housing (130) and can be implemented to rotate in a forward direction (e.g., counterclockwise in FIG. 4) or a backward direction (e.g., clockwise in FIG. 4) with respect to the first housing (130). In addition, handles may be provided on both sides of the first housing (130) so that the user can easily operate the lever. The load part (120) may be implemented to move forward or backward according to the rotation of the lever (150), and since the structure that enables the forward or backward movement of the load through the lever (150) is widely known, a detailed description of the operating method of the lever (150) will be omitted in this specification.

[0066] For example, as illustrated in FIG. 4, in a state where a portion of the front end of the male receptacle (100) is inserted into the female receptacle (200) to fasten the male receptacle (100) and the female receptacle (200), when the user rotates the lever (150) in the front direction, the load part (121, 122) can advance inside the first housing (130).

[0067] Then, as described above, the male poppet valve (110) moves forward and comes into contact with the female poppet valve (220), and in the contact state, both the male poppet valve (110) and the female poppet valve (220) can be opened. Then, fuel can be moved from the male receptacle (100) to the female receptacle (200).

[0068] In addition, when a user rotates the lever (150) in the shear direction while a portion of the front end of the male receptacle (100) is inserted into the female receptacle (200), the hook (162) provided in the hook part (160) is engaged with the notch (240) provided in the female receptacle (200), thereby stably engaging the male receptacle (100) and the female receptacle (200).

[0069] Ultimately, according to the technical idea of ​​the present invention, the stable connection of the male receptacle (100) and the female receptacle (200) and the opening of the male poppet valve (110) and the female poppet valve (220) are all possible by simply rotating the lever (150), and thus, the connection of the receptacle device (1) is effected more quickly and easily than in the conventional method.

[0070] In addition, when releasing the receptacle device (1), the male receptacle (100) and the female receptacle (200) can be simply separated by simply rotating the lever (150), as will be described later. In addition, in the case of the conventional method of directly turning a screw to fasten or loosen the screw, the risk of using cryogenic fluids as fuel is also significantly reduced.

[0071] The above female receptacle (200) includes a second housing (230), a male receiving portion (210), and a female poppet valve (220).

[0072] The second housing (230) above has a notch (240) formed at the front end (i.e., toward the side of the male receptacle (100)), so that the male receptacle (100) and the female receptacle (200) can be connected by fastening the notch (240) with the hook (162) provided in the male receptacle (100).

[0073] The above mail receiving portion (210) may be configured to form a space into which the front end of the mail receptacle (100) can be inserted and received, and may be formed inside the second housing (230). The mail receiving portion (210) may be formed to a predetermined length of the front end of the second housing (230) and may be configured to receive the front end of the mail receptacle (100) inside.

[0074] The above female poppet valve (220) is formed at the rear end of the above male receiving portion (210) and can be implemented so that the front end of the above male receptacle (100) can be opened by coming into contact with the above male poppet valve (110) when it is received in the above male receiving portion (210).

[0075] In addition, the second housing (230) may be implemented to include a second outer housing (232) and a second inner housing (231). The second inner housing (231) may be implemented to be accommodated in the second outer housing (232), form a vacuum separation space with the second outer housing (232), and accommodate the male receiving portion (210) and the female poppet valve (220).

[0076] In addition, the second inner housing (231) is formed at a position corresponding to the rear end of the mail receiving portion (210) and may include a protruding part (231-1) that protrudes inwardly to limit the forward movement of the female poppet valve (220) or the male receptacle (100). For example, the protruding part (231-1) may be formed to protrude inwardly by a predetermined length at the upper and lower portions of the rear end of the mail receiving portion (210), and the female poppet valve (220) is limited by the protruding part (231-1) so as to no longer move forward (in the direction of the male receptacle (100)), and the movement of the male receptacle (100) may also be limited so as to no longer move forward in the forward direction (in the direction of the female poppet valve (220)).

[0077] The notch formed in the second housing (230) is formed at the front end of the second housing, and can be implemented so that when the front end of the male receptacle (100) is inserted into the female receptacle (200), it is inserted between the hook part (160) and the first housing (130).

[0078] One embodiment of the above hook part (160) will be described with reference to FIGS. 7 and 8.

[0079] FIG. 7 and FIG. 8 are drawings for explaining a hook part according to an embodiment of the present invention.

[0080] A hook part (160) according to an embodiment of the present invention is provided in the shear direction of the lever (150) and may include a hook body (161), a hook (162), and a hook cover (163).

[0081] The above hook body (161) is formed to surround a portion of the rear end of the first housing (130), and may be formed to have a predetermined space from the first housing so that the front end of the female receptacle (200) can be inserted when the male receptacle (100) and the female receptacle (200) are connected.

[0082] A hook groove (164) is formed in the above hook body (161), and at least the front end of the hook (162) or the entire hook (162) can be installed to be received in the hook groove (164). Then, when the front end of the female receptacle (200) is slidably inserted between the hook body (161) and the first housing (130), the notch (240) installed at a predetermined position in the front end of the female receptacle (200) and the hook (162) can be connected or disconnected.

[0083] The front end of the above hook (162) is coupled with the hook body (161) so that it can rotate up and down and can be engaged or disengaged with the notch (240).

[0084] The above hook cover (163) can control the rotation of the front end of the hook (162) by moving forward or backward according to the rotation of the lever (150) to press and fix the hook (162) into a state of engagement with the notch (240) or by lifting the front end of the hook (162) so as to release it from the notch (240).

[0085] A guide pin (165) may be formed at the rear end of the above hook cover (163) to move the hook cover (163) forward in the front direction or backward in the rear direction according to the rotation of the lever (150), and the hook cover (163) may move forward or backward by this guide pin.

[0086] Referring to FIG. 8, when the front end of the male receptacle (100) is inserted into the female receptacle (200) and the lever (150) is rotated in the front direction to fasten the male receptacle (100) and the female receptacle (200), the notch (240) formed at a predetermined position in the front end of the female receptacle (200) is slidably inserted into the space between the hook body (161) and the first housing (130), and the front end (162-1) of the hook (162) can advance further than the notch (240) and be fastened with the notch (240).

[0087] At this time, the hook cover (163) also moves forward, and the hook (162) is pressed downward by a knob (knob, 163-1) located at the front end of the hook cover (163) and protruding downward (toward the first housing (130)) so that it can be fixed in a state of being connected to the notch (240).

[0088] Thereafter, in order to separate the male receptacle (100) and the female receptacle (200), the user can rotate the lever (150) in the rearward direction, and then the hook cover (163) can be moved backward by the guide pin (165). Then, the knob (163-1) of the hook cover (163) also moves backward and presses downward the inclined portion of the rear end (162-2) of the hook, and accordingly, the front end (162-1) of the hook is rotated to be lifted upward, so that the fastening between the notch (240) and the hook (162) can be released.

[0089] Ultimately, according to the technical idea of ​​the present invention, a user can easily connect the male receptacle (100) and the female receptacle (200) by simply rotating the lever (150) in the forward direction after inserting the front end of the male receptacle (100) into the female receptacle (200), and at the same time, by bringing the male poppet valve (110) and the female poppet valve (220) into contact with each other to open both valves (110, 220), the fuel can be moved to the female receptacle (200). In addition, the male receptacle (100) and the female receptacle (200) can be easily separated (released) simply by rotating the lever (150) in the rearward direction, and the contact between the male poppet valve (110) and the female poppet valve (220) is released, thereby allowing both valves (110, 220) to be closed.

[0090] FIG. 5 and FIG. 6 are drawings for explaining a fuel injection process of a receptacle device according to an embodiment of the present invention.

[0091] FIG. 5 illustrates an example in which the front end of the male receptacle (100) is inserted into the female receptacle (200) and the lever (150) is rotated in the front direction so that the poppet tip (111) of the male poppet valve (110) comes into contact with the poppet tip (221) of the female poppet valve (220).

[0092] As the body load (121) of the load part (120) moves forward in accordance with the forward rotation of the lever (150), the male poppet valve (110) can be moved forward, and when the poppet tip (111) of the male poppet valve (110) begins to contact the poppet tip (221) of the female poppet valve (220), the poppet tip (111) is pressured in the rearward direction (rightward direction in FIG. 5), so that the male poppet valve (110) can be opened.

[0093] In addition, the poppet tip (221) formed on the female poppet valve (220) may also come into contact with the poppet tip (111) of the male poppet valve (110) and be pressured toward the rear end of the female receptacle (200) (left side in FIG. 5), thereby allowing the female poppet valve (220) to open. Then, as illustrated in FIG. 6, fuel may move from the male receptacle (100) to the female receptacle (200) along a movement path as illustrated by the arrow.

[0094] In addition, as described above, when the male receptacle (100) is inserted into the female receptacle (200), the hook (162) installed in the hook groove (164) of the hook body (161) can advance further than the notch (240) formed in the front end of the female receptacle (200), and the hook cover (163) can also advance according to the rotation of the lever (150) in the front direction to press the hook (162) downward, thereby fixing the connection between the notch (240) and the hook (162).

[0095] Thereafter, when the lever (150) rotates in the rearward direction, the front end of the hook (162) is lifted due to the backward movement of the hook cover (163), thereby releasing the engagement with the notch (240), and the body load (121) moves backward, thereby releasing the contact between the male poppet valve (110) and the female poppet valve (220), and the poppet body (112) of the male poppet valve (110) receives an elastic force in the frontward direction (leftward in FIG. 5) by the spring (113), thereby closing the valve, and the poppet body (222) of the female poppet valve (220) also receives an elastic force in the frontward direction (rightward in FIG. 5) by the spring (223), thereby closing the valve.

[0096] Meanwhile, FIG. 9 is a drawing for explaining in more detail the operation process of poppet valves according to an embodiment of the present invention, and FIG. 10 is a drawing for explaining a schematic configuration of a poppet valve according to an embodiment of the present invention.

[0097] First, as shown in Fig. 9a, before the male poppet valve (110) and the female poppet valve (220) come into contact, the male poppet valve (110) and the female poppet valve (220) may be closed by springs (113, 223) each having a shear-direction elastic force.

[0098] And as shown in FIG. 9b, when the lever (150) rotates in a certain shear direction, the poppet tips (111, 221) of the male poppet valve (110) and the female poppet valve (220) come into contact and begin to push each other, and at this time, the elastic coefficient of the spring (223) for the female poppet valve (220) is implemented to be greater than the elastic coefficient of the spring (113) for the male poppet valve (110), so that the male poppet valve (110) can be opened as the male poppet valve (110) is pushed in the rearward direction.

[0099] Afterwards, when the lever (150) is rotated further, the male poppet valve (110) is no longer pushed backward by the stopper (112-1) provided in the male poppet valve (110), as shown in FIG. 9c, and the male poppet valve (220) pushes the female poppet valve (220) backward, so that the female poppet valve (220) can be opened.

[0100] As illustrated in FIGS. 10 a and 10 c, the male poppet valve (110) has a poppet body (112) and a poppet tip (111), and when a stopper (112-1) formed at a predetermined position of the poppet body (112) meets an extension (131-3) that accommodates a spring (113), the male poppet valve (110) can no longer be pushed in the rearward direction. In addition, the female poppet valve (220) can have a poppet body (222) and a poppet tip (221), as illustrated in FIG. 10 b, and both the male poppet valve (110) and the female poppet valve (220) can be implemented as a 2-way valve in which the valve is opened when the poppet tip (111, 2221) receives a pressure of a certain level or more in the rearward direction. However, an average expert in the art of the present invention will be able to easily infer that the shape and operation of the poppet valve may vary.

[0101] The foregoing description of the present invention is for illustrative purposes only, and those skilled in the art will readily appreciate that the present invention can be readily modified into other specific forms without altering the technical spirit or essential characteristics thereof. Therefore, it should be understood that the embodiments described above are exemplary in all respects and not restrictive. For example, each component described as a single component may be implemented in a distributed manner, and similarly, components described as distributed may be implemented in a combined manner. The scope of the present invention is indicated by the claims described below rather than the detailed description above, and all changes or modifications derived from the meaning and scope of the claims and their equivalent concepts should be interpreted as being included in the scope of the present invention.
