Description

Technical Field

[0001] This application relates to the field of electric vehicle discharge, and in particular to an electric vehicle charging port adapter. Background Technology

[0002] As the number of new energy vehicles continues to grow, special functions on these vehicles are gradually being developed, including the electric vehicle's discharge function. This function lowers the barrier to outdoor camping, allowing users to power their camping appliances such as induction cookers and electric hot pots simply by carrying an adapter, eliminating the need to carry heavy outdoor power supplies.

[0003] Currently, conventional adapters include five-hole sockets, but the output current of these five-hole sockets is usually 10A. When the plug of an external appliance is inserted into the socket, the micro switch in the socket controls the circuit to connect, thereby enabling the current to be delivered and powering the appliance.

[0004] However, since high-power electrical equipment is often used when camping outdoors, a 10A output current will not be enough to power these high-power appliances. Summary of the Invention

[0005] In order to provide a sufficiently strong current to electrical equipment, this application provides an electric vehicle charging socket adapter.

[0006] This application provides an electric vehicle charging port adapter, which adopts the following technical solution:

[0007] An electric vehicle charging socket adapter includes a housing. One end of the housing has a vehicle plug end for connecting to an electric vehicle charging socket, and the other end has a five-hole socket for discharging the electric vehicle. The five-hole socket includes a base and a panel. The base is installed inside the housing, and the panel is installed on the base. The base has a protective device, which includes a two-prong protection component and a three-prong protection component that are independent of each other. The base also has a two-prong micro switch and a three-prong micro switch. The two-prong protection component is used to control the operation of the two-prong micro switch. The three-prong protection component includes a three-prong protection plate and a three-prong return spring. The three-prong protection plate is slidably installed on the panel. One end of the three-prong return spring is connected to the three-prong protection plate, and the other end is connected to the panel. The three-prong protection plate has a three-prong slide rail, and the three-prong protection plate is used to control the operation of the three-prong micro switch.

[0008] By adopting the above technical solution, two-prong and three-prong micro switches are installed on the base. This allows the two-prong micro switches to control the on / off state of a 10A circuit, and the three-prong micro switches to control the on / off state of a 16A circuit, thus providing sufficient current to external devices. Furthermore, by incorporating protective devices within the five-hole socket, the two-prong and three-prong protective components protect the socket when it is not in use, reducing the risk of accidental circuit activation and subsequent current transmission disruption.

[0009] In one specific implementation, a second sliding groove is provided on the side wall of the three-pronged protective plate, and a sliding strip is installed on the inner wall of the panel. The three-pronged protective plate is installed on the sliding strip through the second sliding groove.

[0010] By adopting the above technical solution, when the three-prong plug is plugged into the panel, the plug drives the three-prong protection plate to slide along the slide bar, thereby causing the three-prong protection plate to touch the three-prong micro switch, thus opening the 16A circuit so as to provide a sufficient current to the electrical equipment.

[0011] In one specific implementation, the two-plug protection assembly includes two-plug protection plates and two-plug return springs. The two-plug protection plates are slidably mounted on the panel, and one end of the two-plug return springs is connected to the two-plug protection plates, while the other end is connected to the panel.

[0012] By adopting the above technical solution, when the plug of a 10A electrical device is inserted into the socket, the plug drives the two-prong protection plate to slide along the slide bar, thereby causing the two-prong protection plate to contact the two-prong micro switch, so as to open the 10A circuit and supply power to the electrical device. When the plug is pulled out of the panel, the two-prong protection plate is reset by the action of the two-prong reset spring, so as to protect the 10A socket.

[0013] In one specific implementation, the side wall of the two-plug protection plate is provided with two plug slides, and the two-plug protection plate is used to control the operation of the two-plug micro switch.

[0014] By adopting the above technical solution, the two insert protection plates slide along the slide bar via the slide rail, so as to maintain the stability of the sliding of the two insert protection plates.

[0015] In one specific implementation, the two-insert protection plate is also provided with a three-insert positioning groove.

[0016] By adopting the above technical solution, and by setting a three-prong positioning groove on the two-prong protection plate, the two-prong protection plate is kept stationary when the plug of the 16A electrical equipment is plugged into the panel, thereby reducing the occurrence of accidental contact.

[0017] In one specific implementation, the panel is provided with a buffer assembly for cushioning the two-prong and three-prong protective plates. The buffer assembly includes a first buffer member, which includes a buffer plate and a buffer strip. The buffer plate is installed on the panel and is located between the two-prong and three-prong protective plates. A buffer groove is formed on the inner wall of the panel. One end of the buffer strip is connected to the buffer plate, and the other end extends into the buffer groove. The buffer strip is a flexible component.

[0018] By adopting the above technical solution, when the plug of the 10A electrical equipment is pulled out from the panel, the two-plug protection board is reset under the action of the two-plug reset spring, and is buffered by the buffer strip, thus facilitating the protection of the two-plug protection board.

[0019] In one specific implementation, the buffer assembly further includes a locking element, which includes a locking plate and a locking strip. An installation groove is formed on the inner wall of the panel, communicating with a buffer groove. The locking plate is mounted in the installation groove via a pivot. A spring is installed in the installation groove and connected to the locking plate. The side wall of the locking plate abuts against the side walls of the two insert protective plates. A rotating block is installed on the side wall of the locking plate near the buffer groove. The locking strip is installed in the buffer groove. One end of the locking strip near the locking plate has a pusher for pushing the rotating block, and the other end of the locking strip is connected to the buffer strip.

[0020] By adopting the above technical solution, when the two-plug protection plate is reset, the two-plug protection plate causes the buffer strip to deform, thereby causing the buffer strip to move the locking strip, which in turn causes the push block on the locking strip to rotate, and the rotating block to rotate the locking plate, thereby locking the two-plug protection plate. This ensures the stability of the two-plug protection plate when the socket is not in use, thus improving the protection effect of the two-plug protection plate.

[0021] In one specific implementation, the locking bar has a waist-shaped groove at one end near the buffer bar, and the end of the buffer bar located in the buffer groove is connected to the locking bar located in the waist-shaped groove.

[0022] By adopting the above technical solution, when the plug of the electrical equipment is pulled out of the socket, the two plug protection plates are reset under the action of the two plug reset springs, thereby squeezing the buffer strip, causing the buffer strip to deform and slide in the waist-shaped groove, and abut against the side wall of the waist-shaped groove, pushing the locking strip away from the buffer plate, so as to lock the two plug protection plates.

[0023] In one specific implementation, the buffer assembly further includes a second buffer component, which comprises several buffer blocks disposed on the inner wall of the panel. The buffer blocks are used to buffer the reset of the three-pronged protection plate, and the buffer blocks are made of insulating rubber.

[0024] By adopting the above technical solution, when the three-prong protection board is reset, the buffer block buffers the three-prong protection board to protect it and extend its service life.

[0025] In one specific implementation, the stop assembly further includes a positioning element, which includes a positioning strip. A limiting groove is formed on the inner wall of the panel near the three-pronged protective plate. One end of the positioning strip is installed in the limiting groove, and the other end of the positioning strip extends toward the three-pronged protective plate. The positioning strip is used to limit the three-pronged protective plate after reset.

[0026] By adopting the above technical solution, when the three-plug protection board is reset, the positioning strip protrudes out of the limiting groove and abuts against the end of the three-plug protection board, thereby realizing the positioning of the three-plug protection board, so as to improve the protection effect of the three-plug protection board on the 16A circuit.

[0027] In summary, this application includes at least one of the following beneficial effects:

[0028] 1. This application provides a protective device to facilitate the protection of the five-hole socket, thereby reducing the occurrence of accidental contact.

[0029] 2. This application provides a two-prong micro switch and a three-prong micro switch, which facilitates the control of the 10A circuit by the two-prong micro switch and the control of the 16A circuit by the three-prong micro switch, so as to provide sufficient current to the electrical equipment according to the power requirements of the equipment.

[0030] 3. This application incorporates a buffer component to facilitate the reset of the two-prong and three-prong protection boards, thereby extending their service life. A locking component locks the reset two-prong protection board, and a positioning component positions the reset three-prong protection board, ensuring their stability. Attached Figure Description

[0043] The present application will be further described in detail below with reference to the accompanying drawings.

[0044] This application discloses an electric vehicle charging port adapter, referring to... Figure 1 and Figure 2The device includes a housing 1, one end of which is fixedly fitted with a vehicle plug terminal that connects to the charging port of an electric vehicle, and the other end of which is fixedly fitted with a five-hole socket 2 for discharging the electric vehicle.

[0045] Reference Figure 1 and Figure 2 When using a 10A circuit, the protection device 3 touches the two-prong microswitch 23, which then controls the 10A circuit to power the device requiring 10A current. When a 16A circuit is required, the protection device 3 touches the three-prong microswitch 24, which then controls the 16A circuit to power the device requiring 16A current. Both the two-prong microswitch 23 and the three-prong microswitch 24 are existing technologies in the art and will not be described in detail here.

[0046] Reference Figure 3 and Figure 4 The protection device 3 includes a two-plug protection assembly, which includes a two-plug protection plate 31 and a two-plug return spring 32. A slider is fixedly installed on the side wall of the panel 21 near the base 22. Both ends of the two-plug protection plate 31 are provided with a sliding groove 313.

[0047] Reference Figure 5 and Figure 6The protection device 3 includes a three-prong protection assembly, which comprises a three-prong protection plate 33 and a three-prong return spring 34. Both ends of the three-prong protection plate 33 have sliding grooves 331, and the three-prong protection plate 33 is slidably connected to a slider via the sliding grooves 331.

The three-prong return spring 34 is mounted on the panel 21, with one end abutting against the side wall of the three-prong protection plate 33 and the other end connected to the inner wall of the panel 21.

[0048] Reference Figure 7 A buffer assembly 4 is installed on the panel 21 to cushion the two-pronged protective plate 31 and the three-pronged protective plate 33. The buffer assembly 4 includes a first buffer member, which includes a buffer plate 41 and a buffer strip 42. The buffer plate 41 is fixedly installed on the inner wall of the panel 21 and is located between the two-pronged protective plate 31 and the three-pronged protective plate 33. A buffer groove 211 is formed on the inner wall of the panel 21 near the buffer plate 41. The buffer strip 42 is installed on the buffer plate 41, and one end of the buffer strip 42 is fixedly connected to the side wall of the buffer plate 41, while the other end extends into the buffer groove 211. The buffer strip 42 is made of elastic material.

[0049] Reference Figure 7 and Figure 8 The buffer assembly 4 also includes a locking component, which includes a locking plate 44 and a locking strip 43. A mounting groove 212 is provided on the inner wall of the panel 21 near the two-insertion protective plates 31. The mounting groove 212 communicates with the buffer groove 211. The locking plate 44 is rotatably mounted in the mounting groove 212 via a pivot, and the side wall of the locking plate 44 abuts against the side wall of the two-insertion protective plates 31. A spring piece 45 is also installed in the mounting groove 212. One end of the spring piece 45 is fixedly connected to the side wall of the mounting groove 212, and the other end abuts against the locking plate 44. A rotating block 441 is fixedly mounted on the side wall of the locking plate 44 near the pivot, and the right-angled side of the rotating block 441 is perpendicular to the locking plate 44. The locking bar 43 is slidably installed in the buffer groove 211, and a push block 432 is fixedly installed at one end of the locking bar 43 near the rotating block 441. The other end of the locking bar 43 has a waist-shaped groove 431. The waist-shaped groove 431 is set on the locking bar 43 in an inclined upward direction, and one end of the waist-shaped groove 431 is located near the buffer plate 41, and the other end extends towards the two insert protection plates 31. One end of the buffer bar 42 located in the buffer groove 211 is slidably connected to the locking bar 43 through the waist-shaped groove 431.

[0050] Reference Figure 7 and Figure 9When a 10A circuit is required, when the plug of the electrical device is inserted into the panel 21, the metal terminals of the plug abut against the two-plug slide rail 314 on the two-plug protection plate 31 and slide along the two-plug slide rail 314, thereby causing the two-plug protection plate 31 to slide away from the buffer plate 41, thereby driving the locking plate 44 to rotate towards the buffer groove 211, thereby causing the rotating block 441 on the locking plate 44 to press the spring piece 45 and slide along the surface of the spring piece 45, pushing the push block 432 towards the buffer plate 41, and causing the end of the locking plate 44 to slide along the side wall of the two-plug protection plate 31, thereby causing the two-plug protection plate 31 to touch the two-plug micro switch 23, thereby controlling the 10A circuit to open and thus supplying power.

[0051] Reference Figure 7 and Figure 9 When the electrical equipment is unplugged from the panel 21, the metal terminals of the plug separate from the two-plug protection plate 31, thereby causing the two-plug protection plate 31 to reset under the action of the two-plug reset spring 32. The two-plug protection plate 31 presses the buffer strip 42, causing the buffer strip 42 to deform and drive the locking strip 43 to move away from the buffer strip 42. This causes the push block 432 on the locking strip 43 to push the rotating block 441 to rotate. At the same time, the locking plate 44 rotates and resets under the action of the spring piece 45, causing the rotating block 441 to drive the locking plate 44 to rotate away from the buffer groove 211, thereby limiting the two-plug protection plate 31.

[0052] Reference Figure 7 The buffer assembly 4 also includes a second buffer component, which includes several buffer blocks 47. The buffer blocks 47 are fixedly installed on the side wall of the panel 21. The buffer blocks 47 are insulating rubber parts and are used to buffer the reset of the three-pin protection plate 33.

[0053] Reference Figure 7 The stop assembly 4 also includes a positioning element, which includes a positioning strip 46. A limiting groove 213 is provided on the inner wall of the panel 21 near the three-insert protection plate 33. One end of the positioning strip 46 is fixedly installed in the limiting groove 213, and the other end extends outward from the positioning groove. The other end of the positioning strip 46 abuts against the side wall of the three-insert protection plate 33.

[0054] Reference Figure 7 and Figure 10 When the 16A circuit is needed, the plug of the electrical equipment is inserted into the panel 21, so that the metal terminals on the plug abut against the three-prong slide rail 332 and slide along the three-prong slide rail 332. The metal terminals on the plug near the two-prong protection plate 31 are inserted into the three-prong positioning groove 312, thereby pushing the three-prong protection plate 33 toward the three-prong micro switch 24, so that the three-prong protection plate 33 touches the three-prong micro switch 24, thereby controlling the 16A circuit to open.

[0055] Reference Figure 7 and Figure 10 When the plug of the electrical equipment is pulled out from the panel 21, the three-prong protection plate 33 is reset under the action of the three-prong reset spring 34 and is buffered by the buffer block 47. After the three-prong protection plate 33 is reset, the end of the positioning strip 46 away from the limiting groove 213 abuts against the end of the three-prong protection plate 33, thereby limiting the three-prong protection plate 33.

[0056] The working principle of this application embodiment is as follows: when a 10A circuit is required, the plug of the electrical equipment is plugged into the panel 21, thereby driving the two-plug protection plate 31 to move towards the two-plug micro switch 23 and touch the two-plug micro switch 23, thereby enabling the two-plug micro switch 23 to control the 10A circuit to open.

[0057] When the plug of the electrical equipment is pulled out from the panel 21, the two-plug protection plate 31 is reset by the action of the two-plug reset spring 32, and the two-plug protection plate 31 is buffered by the stop assembly 4. After the two-plug protection plate 31 is reset, the two-plug protection plate 31 is positioned by the locking member in the stop assembly 4.

[0058] When the 16A circuit is needed, plug the electrical equipment into the panel 21, thereby moving the three-prong protection board 33 toward the three-prong micro switch 24 and touching the three-prong micro switch 24, thereby enabling the three-prong micro switch 24 to control the 16A circuit to open.

[0059] When the plug of the electrical equipment is unplugged from the panel 21, the three-prong protection plate 33 is reset by the action of the three-prong reset spring 34 and is buffered by the second buffer. After the three-prong protection plate 33 is reset, the positioning component positions the three-prong protection plate 33.

[0060] The above are preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made to the structure, shape and principle of this application should be included within the scope of protection of this application.
