Description

Technical Field

[0001] The utility model relates to a power supply adapter device, in particular to an off-vehicle power supply adapter device with a hovering dust cover. Background Art

[0002] To make existing electric vehicles more flexible in their power usage, users often use an external discharge device to distribute the stored energy from the vehicle to other devices. Existing external discharge devices typically consist of a nozzle, a socket, and a flip-up dust cover. The nozzle connects to the vehicle, the socket allows other devices to plug in, and the flip-up dust cover protects the socket from water and dust.

[0003] However, after opening upward, the conventional flip-up dust cover of the external discharge device of an energy vehicle tends to close again due to the influence of gravity. Therefore, when a plug of another device is plugged into the receptacle of the external discharge device of the energy vehicle, the closing of the flip-up dust cover can cause the wire connected to the plug to bend and become easily damaged.

[0004] In view of this, proposing a better improvement solution is an urgent problem to be solved in this industry. Utility Model Content

[0005] The main purpose of the present utility model is to provide an off-vehicle power supply adapter with a hovering dust cover. This device is used to solve the problem that the flip-up dust cover of the external discharge device of the existing energy vehicle often tends to close again due to the influence of gravity after opening upward, causing the wires connected to the plug to bend and easily damage.

[0006] To achieve the above-mentioned objectives, the present invention provides an off-vehicle power supply adapter device that can be connected to an energy vehicle and has:

[0007] a housing;

[0008] a gun head located at one end of the housing and capable of being connected to the energy vehicle;

[0009] A socket, located on the other end of the housing relative to the gun head and electrically connected to the gun head, and having:

[0010] A fixing member is provided on a side of the socket away from the housing and has:

[0011] two rotating shafts protruding from opposite ends of the fixing member;

[0012] A dust cover connected to and capable of selectively covering the socket, and comprising:

[0013] Two limiting portions are connected to the inner surface of the dust cover, and each limiting portion has:

[0014] The two rotating shafts can be passed through the two fixing holes, and the spacing between the two limiting portions is smaller than the length of the fixing member, so that when the dust cover is opened, the fixing member can be pressed against between the two limiting portions and cannot rotate.

[0015] As described above, each of the fixing holes of the off-vehicle power supply adapter is in the shape of an oblong hole and has:

[0016] a first end, which is an end of the fixing hole away from the socket;

[0017] a second end, which is the other end of the fixing hole opposite to the first end;

[0018] When the dust cover is closed, the rotating shaft is located at the first ends of the two fixing holes; when the dust cover is opened, the rotating shaft is located at the second ends of the two fixing holes.

[0019] As mentioned above, the off-vehicle power supply adapter device

[0020] The housing has:

[0021] At least one fastening member is disposed at one end of the housing close to the socket and extends outward;

[0022] The dust cover has:

[0023] The number of at least one buckle ring corresponds to the number of the at least one fastening member, and each of the at least one fastening member can be fastened to one of the at least one buckle ring.

[0024] As mentioned above, the socket of the off-vehicle power supply adapter has:

[0025] a protecting portion, which can be attached to the inner surface of the housing, and the fixing member is disposed on the protecting portion;

[0026] A socket circuit portion is arranged on the protection portion, located in the shell, and electrically connected to the gun head.

[0027] As described above, the outer vehicle power supply adapter has at least one protrusion extending from a side of the shell close to the dust cover toward the dust cover. When the dust cover is closed, the at least one protrusion can fit against the inner surface of the dust cover.

[0028] The off-vehicle power supply adapter proposed in this utility model can be connected to an energy vehicle and has:

[0029] A housing having:

[0030] A fixing member is provided at one end of the housing and has:

[0031] two rotating shafts protruding from opposite ends of the fixing member;

[0032] a gun head, which is located on the other end of the housing relative to the fixing member and can be connected to the energy vehicle;

[0033] a socket located at the end of the housing having the fixing member and electrically connected to the gun head;

[0034] A dust cover connected to and capable of selectively covering the socket, and comprising:

[0035] Two limiting portions are connected to the inner surface of the dust cover, and each limiting portion has:

[0036] The two rotating shafts can be passed through the two fixing holes, and the spacing between the two limiting portions is smaller than the length of the fixing member, so that when the dust cover is opened, the fixing member can be pressed against between the two limiting portions and cannot rotate.

[0037] The advantage of this invention lies in that by designing the spacing between the two limiting portions to be smaller than the length of the fixing member, the fixing member can rest between the two limiting portions, preventing rotation and thus achieving a suspended dust cover. Furthermore, the locking relationship between the fastener and the buckle, as well as the shape of the fixing hole, prevent the dust cover from accidentally flipping open and allowing dust or moisture to enter the socket.

[0045] The following is a detailed description of the technical means used by the present invention to achieve the intended purpose of the present invention with reference to the drawings and preferred embodiments of the present invention.

[0046] Please refer to Figure 1 、 Figure 2 and Figure 4 . The utility model proposes an off-vehicle power supply adapter device, which can be connected to an energy vehicle and has a shell 10, a gun head 20, a socket 30 and a dust cover 40. The gun head 20 and the socket 30 are respectively located at opposite ends of the shell 10. The shell 10 has at least one fastener 11 and at least one protrusion 12. The fastener 11 and the protrusion 12 are both arranged at one end of the shell 10 close to the socket 30 and extend outward. Among them, the fastener 11 has a hook portion, which is bent toward the inner side of the shell 10.

[0047] Please refer to Figures 2 to 4 . The gun head 20 is located at one end of the shell 10 and can be connected to the energy vehicle. The socket 30 is located on the other end of the shell 10 relative to the gun head 20 and is electrically connected to the gun head 20, whereby the electric energy of the energy vehicle is transferred to the socket 30 via the gun head 20 and supplied to other devices plugged into the socket 30. The socket 30 has a fixing part 31, a protective part 32, and a socket circuit part 33. The fixing part 31 is arranged on a side of the socket 30 away from the shell 10 and has two rotating shafts 311. The two rotating shafts 311 protrude from the opposite ends of the fixing part 31 respectively. The protective part 32 can fit the inner surface of the shell 10, and the fixing part 31 is arranged on the protective part 32. In the first embodiment, the material of the protective part 32 is elastic, so it can fit better to the inner surface of the shell 10 and prevent dust or moisture from entering the interior of the shell 10 and affecting the electrical connection between the socket 30 and the gun head 20. The socket circuit portion 33 is disposed on the protection portion 32 , is located inside the housing 10 , and is electrically connected to the gun head 20 .

[0048] Please refer to Figures 2 to 4 . The dust cover 40 is connected to and can selectively cover the socket 30, so the dust cover 40 is pivotally mounted on the socket 30. The dust cover 40 has two limiting portions 41 and at least one buckle 42. The limiting portions 41 are connected to the inner surface of the dust cover 40, and each limiting portion 41 has two fixing holes 411. The two rotating shafts 311 of the socket 30 can be passed through the two fixing holes 411, and the spacing between the two limiting portions 41 is smaller than the length of the fixing member 31, so that when the dust cover 40 is opened, the fixing member 31 can be abutted between the two limiting portions 41 and cannot rotate therein. In addition, in the first embodiment, the material of the fixing member 31 is elastic, so when the fixing member 31 is abutted between the two limiting portions 41, the two limiting portions 41 can squeeze the fixing member 31, so that the fixing member 31 is more tightly engaged between the two limiting portions 41 and cannot rotate.

[0049] Please refer to Figures 5 to 7. In the first embodiment, each fixing hole 411 is in the shape of an oblong hole and has a first end 421 and a second end 422. The first end 421 is the end of the fixing hole 411 away from the socket 30, and the second end 422 is the other end of the fixing hole 411 relative to the first end 421. When the dust cover 40 is closed, the rotating shaft is located at the first end 421 of the two fixing holes 411, and when the dust cover 40 is opened, the rotating shaft is located at the second end 422 of the two fixing holes 411. Therefore, when the dust cover 40 is to be opened, it is necessary to first pull the dust cover 40 away from the socket 30 before the dust cover 40 can be opened and flipped open. In this way, the dust cover 40 can be prevented from being accidentally touched and flipped open, causing dust or moisture to enter the socket 30.

[0050] The number of buckles 42 corresponds to the number of fastening members 11, and each fastening member 11 can be fastened to one of the buckles 42. Specifically, the hook portion of each fastening member 11 can hook onto the corresponding buckle 42, preventing the dust cover 40 from being opened by accident. In other embodiments, the positions of the buckles 42 and fastening members 11 are not limited to this. Alternatively, the buckles 42 can be positioned on the housing 10, and the fastening members 11 can be positioned on the dust cover 40.

[0051] The second embodiment of the present invention (not shown) has similar technical features to the first embodiment, differing only in that the fixing member 31 is disposed on the housing 10 rather than the socket 30. Specifically, the fixing member 31 is disposed on the end of the housing 10 closest to the socket 30, and the two rotating shafts 311 of the fixing member 31 protrude from opposite ends of the fixing member 31. Therefore, the dust cover 40 of the second embodiment is pivotally mounted on the housing 10.

[0052] When using the present invention, the user connects the gun head 20 to the power vehicle and then opens the dust cover 40. At this point, because the distance between the two limiting portions 41 is smaller than the length of the fixing member 31, the dust cover 40 will be deformed by the two limiting portions 41 and the fixing member 31 during the opening process. This causes the fixing member 31 to be clamped between the two limiting portions 41 and prevented from rotating, thereby achieving the effect of hovering the dust cover 40. When the dust cover 40 is open and hovering, the user can plug a device that requires electrical energy into the socket 30 without the dust cover 40 closing automatically due to gravity and bending the wires connected to the socket 30.

[0053] The advantage of this invention lies in that by designing the spacing between the two limiting portions 41 to be smaller than the length of the fixing member 31, the fixing member 31 can rest between the two limiting portions 41 and prevent rotation, thereby achieving a suspended effect on the dust cover 40. Furthermore, the engagement between the fastener 11 and the buckle 42, as well as the shape of the fixing hole 411, prevent the dust cover 40 from being accidentally flipped open, potentially allowing dust or moisture to enter the socket 30.

[0054] The above description is merely a preferred embodiment of the present invention and does not constitute any form of limitation to the present invention. Although the present invention has been disclosed as a preferred embodiment, it is not intended to limit the present invention. Any technician familiar with the profession can make some changes or modifications to the technical contents disclosed above without departing from the scope of the technical solution of the present invention. However, any simple modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention without departing from the content of the technical solution of the present invention are still within the scope of the technical solution of the present invention.
