[0029] The following describes the specific embodiments of the present disclosure in detail with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only used to illustrate and explain the present disclosure and are not intended to limit the present disclosure.
[0030] In this disclosure, unless otherwise indicated, directional terms such as "upper," "lower," "top," and "bottom" generally refer to the upper, lower, top, and bottom positions of the corresponding component in the direction of gravity when in use. "Inside" and "outside" refer to the inside and outside relative to the outline of the component or structure itself. Furthermore, it should be noted that terms such as "first" and "second" are used to distinguish one element from another and do not convey order or importance. Furthermore, in the description with reference to the accompanying drawings, the same reference numerals in different drawings represent the same element.
[0031] like Figure 1-2As shown, the present disclosure provides a vehicle charging structure, including: a mounting base 1 for being installed on a vehicle body, the mounting base 1 being provided with a mounting hole 111 for the charging socket 4 to pass through; a guide rail assembly 3, which is openably and closably arranged on the mounting base 1 and is located on one side of the mounting hole 111, so that the charging gun 2 can be inserted into the guide rail assembly 3 when the charging gun 2 is plugged into the charging socket 4.
[0032] Through the above technical solution, a guide rail assembly 3 is provided on the mounting base 1, and the guide rail assembly 3 is arranged on one side of the mounting hole 111. For example, in the present disclosure, the guide rail assembly 3 is arranged below the mounting hole 111. When the charging gun 2 is plugged into the charging socket 4, the charging gun 2 is inserted into the guide rail assembly 3, and the guide rail assembly 3 supports the charging gun 2 to prevent the charging gun 2 from falling and tilting, and to avoid deformation of the charging socket 4 and poor contact between the charging gun 2 and the charging socket 4.
[0033] As an optional implementation, Figure 3-7 As shown, the mounting base 1 includes a mounting plate 11 and a mounting box 12. The mounting box 12 is arranged on the side of the mounting plate 11 away from the insertion of the charging gun 2. A accommodating cavity 121 for accommodating the guide rail assembly 3 is provided in the mounting box 12. The accommodating cavity 121 is open toward the side where the charging gun 2 is inserted. The guide rail assembly 3 enters and exits the accommodating cavity 121 through the opening. When not in use, the guide rail assembly 3 is retracted into the accommodating cavity 121 and the outer surface is flush with the mounting plate 11 to prevent the guide rail assembly 3 from obstructing the driving of the vehicle when not charging.
[0034] Optionally, the guide rail assembly 3 includes a first guide rail 31 and a second guide rail 32, one end of the first guide rail 31 and the second guide rail 32 extends into the accommodating cavity 121 and is rotatably connected to the installation box 12 through a pin 5, and a cover plate 122 is provided on the upper and lower sides of the installation box 12, and the cover plate 122 is connected to the installation box 12 through a bolt 123. The pin 5 passes through the cover plates 122 on the upper and lower sides and is fixed by a bayonet. A first guide groove 311 is provided on the first guide rail 31, and a second guide groove 321 is provided on the second guide rail 32. The first guide groove 311 and the second guide groove 321 are arranged opposite to each other. Two guide rails are provided to support the charging gun 2, which is more stable. The charging gun 2 is inserted into the first guide groove 311 and the second guide groove 321 and is slidably connected to the guide rail assembly 3.
[0035] Optionally, the first guide rail 31 and the second guide rail 32 overlap when retracted, and the first guide slot 311 is larger than the second guide rail 32, so that the second guide rail 32 can be accommodated in the first guide slot 311. When the guide rail assembly 3 is retracted, the second guide rail 32 can be accommodated in the first guide slot 311. This saves space. To ensure balance of the charging gun 2, the side of the charging gun 2 corresponding to the first guide slot 311 is larger than the side corresponding to the second guide slot 321. Limit pins can be provided on the upper and lower portions of the pin 5 located on the first and second guide rails 31, 32 to prevent the first and second guide rails 31, 32 from moving along the extension direction of the pin 5, which could cause misalignment and prevent the second guide rail 32 from being accommodated in the first guide slot 311. In other embodiments, the first guide rail 31 and the second guide rail 32 may not engage, but rather overlap when retracted, each occupying half of the accommodating cavity 121.
[0036] As an optional implementation, Figure 7 As shown, the guide rail assembly 3 is arranged perpendicular to the mounting base 1 when unfolded. The guide rail assembly 3 plays both a supporting and a guiding role, allowing the charging gun 2 to be vertically inserted into the charging socket 4, avoiding the charging gun 2 from tilting due to different insertion angles when people insert the gun.
[0037] As an optional implementation, Figure 7 As shown, the vehicle charging structure further includes a limiting member 8 and a fixing member 9 to limit and fix the guide rail assembly 3, thereby preventing the guide rail assembly 3 from being deployed when in the retracted state, and also preventing the guide rail assembly 3 from rotating or deflecting when in the deployed state.
[0038] Optionally, the limiting member 8 includes a circular protrusion 81 and a groove 82. The circular protrusion 81 is provided on the inner wall of the installation box 12, and the groove 82 is provided at the end of the first guide rail 31 and the second guide rail 32 extending into the accommodating cavity 121. The circular protrusion 81 for limiting the second guide rail 32 is provided with at least one position corresponding to the position of the second guide rail 32 when it is unfolded, and the circular protrusion 81 for limiting the first guide rail 31 is provided with two positions corresponding to the positions of the second guide rail 32 when it is unfolded and retracted, respectively. The ends of the first guide rail 31 and the second guide rail 32 are both provided with a groove 82, and the groove 82 is engaged with the circular protrusion 81 to engage the first guide rail 31 and the second guide rail 32. Limiting, since the first guide rail 31 is buckled on the outside of the second guide rail 32 when retracted, it is sufficient to fix the first guide rail 31, so a circular protrusion 81 is provided on the second guide rail 32 to limit the position when the second guide rail 32 is unfolded, and two circular protrusions 81 are provided on the first guide rail 31 to limit the position when the first guide rail 31 is unfolded and retracted. The rotation angle of the first guide rail 31 and the second guide rail 32 is 90 degrees. An arc-shaped limiting groove can also be provided on the side wall of the installation box 12. When unfolded, the first guide rail 31 and the second guide rail 32 contact the side wall of the limiting groove to limit the first guide rail 31 and the second guide rail 32. Figure 7 In other embodiments, circular protrusions 81 may be provided at the ends of the first guide rail 31 and the second guide rail 32 , and grooves 82 may be provided on the inner wall of the installation box 12 .
[0039] Optionally, a fixing member 9 is provided at one end of the first guide rail 31 extending outside the accommodating cavity 121. The fixing member 9 is configured as a buckle. The width of the buckle is smaller than the width of the first guide rail 31 so that the side of the buckle facing the second guide rail 32 forms a step surface with the edge of the first guide rail 31. The step surface is provided with a slot 91 that engages with the pin 5. Similarly, when fixing, only the first guide rail 31 is fixed. The buckle forms a step surface with the edge of the first guide rail 31 facing the second guide rail 32. In this way, the slot 91 can engage with the pin 5 when the first guide rail 31 is retracted. If the buckle is flush with the edge of the first guide rail 31, the pin 5 will hinder the engagement of the first guide rail 31, and the first guide rail 31 will be in a tilted state and cannot be fully retracted into the accommodating cavity 121. A pulling member 7 protruding from the mounting plate 11 is provided on the side of the first guide rail 31 facing away from the second guide rail 32. When the first guide rail 31 needs to be opened, a person pulls the pulling member 7 to open the first guide rail 31.
[0040] As an optional implementation, Figure 3As shown, the vehicle charging structure also includes an elastic switch 6, which is arranged on the inner wall of the mounting box 12 away from the mounting plate 11, and the telescopic end of the elastic switch 6 extends into the accommodating cavity 121 to contact the guide rail assembly 3 retracted into the accommodating cavity 121, and the elastic switch 6 contacts the second guide rail 32. A mounting groove is provided on the side wall of the mounting box 12, and the elastic switch 6 is installed in the mounting groove. A spring is provided in the elastic switch 6. When the guide rail assembly 3 is retracted, the elastic switch 6 is compressed, which will give the second guide rail 32 an expansion force. When the first guide rail 31 is opened, the force preventing the second guide rail 32 from expanding is eliminated, and the second guide rail 32 will be popped out by the elastic switch 6. The elastic switch 6 is used to be electrically connected to the vehicle-mounted host. The vehicle-mounted host receives the switch signal of the elastic switch 6. When the guide rail assembly 3 is unfolded, the elastic switch 6 is in a pop-up state, indicating that the vehicle is in a charging state at this time. The vehicle-mounted host receives the signal and prohibits the vehicle from driving; when the guide rail assembly 3 is retracted, the elastic switch 6 is in a compressed state, and the vehicle-mounted host displays a signal that charging is complete and cancels the instruction that the vehicle cannot drive. That is, the vehicle cannot be driven without unplugging the charging gun 2 and retracting the guide rail assembly 3 after charging is completed. This prevents the situation where a person drives without unplugging the charging gun 2 after charging is completed, and the vehicle pulls the charging gun 2, causing damage to the charging pile.
[0041] The second object of the present disclosure is to provide a vehicle charging assembly, including: the above-mentioned vehicle charging structure; and a charging gun 2, which is used to be plugged into the charging socket 4. The charging gun 2 is provided with a support member 21, which can be inserted into the guide rail assembly 3 and slidably connected with the guide rail assembly 3. When the charging gun 2 is plugged into the charging socket 4, the support member 21 is inserted into the guide rail assembly 3, and the guide rail assembly 3 supports the charging gun 2 to prevent the charging gun 2 from falling and tilting, and to avoid deformation of the charging socket 4 and poor contact between the charging gun 2 and the charging socket 4.
[0042] Alternatively, as Figure 1-2 As shown, the support member 21 includes a support plate 211 and a slider 212. One end of the support plate 211 is connected to the charging gun 2, and the other end is connected to the slider 212. The slider 212 is slidably connected to the guide rail assembly 3. The support member 21 is provided with two support plates 211 corresponding to the first guide rail 31 and the second guide rail 32 respectively. The two support plates 211 are unfolded in an eight-shaped shape, and the slider 212 is arranged at the end of the support plate 211 and is slidably connected to the guide rail assembly 3.
[0043] The preferred embodiments of the present disclosure are described in detail above in conjunction with the accompanying drawings. However, the present disclosure is not limited to the specific details of the above embodiments. Within the technical concept of the present disclosure, various simple modifications can be made to the technical solutions of the present disclosure, and these simple modifications all fall within the scope of protection of the present disclosure.
[0044] It should also be noted that the various specific technical features described in the above specific embodiments can be combined in any appropriate manner without contradiction. In order to avoid unnecessary repetition, the present disclosure will not further describe various possible combinations.
[0045] In addition, the various embodiments of the present disclosure may be arbitrarily combined, and as long as they do not violate the concept of the present disclosure, they should also be regarded as the contents disclosed by the present disclosure.
