Description

Technical Field

[0001] This invention relates to a charging gate device. In particular, this invention relates to a charging gate device that adjusts the applied pressure to the charging gate via an operating force correction module installed on a vehicle. Background Technology

[0002] In terms of the process of opening and closing the charging door for charging, when the compressive force of the rubber damper arranged in the outer shell reaches a certain level due to the pressing operation applied to the charging door, the charging switch installed on the outer panel of the outer shell can be pressed.

[0003] On the other hand, the compressive force of the rubber damper exhibits a characteristic of changing by about 1 kgf for every 0.1 mm of compression. Therefore, it is necessary to manage the tolerance variation caused by the structure from the outer panel to the charging switch within 0.2 mm, but this is difficult.

[0004] Furthermore, mass production is difficult to ensure due to variations in the compression force of the rubber damper caused by temperature changes. Additionally, thermal deformation of the external panel caused by changes in the compression of the rubber damper can alter the gap between the charging door and the switch, leading to changes in the operating force. Summary of the Invention

[0046] Reference Figures 1 to 4 An embodiment of the present disclosure includes a charging door device 10 that may include a housing portion 100.

[0047] The housing 100 can accommodate a charging port. The charging port may include charging equipment (not shown) such as a charging socket. For example, the charging port may be fixed to a vehicle body panel and may be connected to an external charging station. For example, the charging port may be electrically connected to a battery provided with the vehicle. The vehicle body panel may form at least a portion of the outer side of the vehicle.

[0048] The housing portion 100 may include a charging port 102 forming an opening of a predetermined size. The charging port 102 may have a structure that extends through the inside of the housing portion 100 along the thickness direction of the vehicle body panel. For example, a charging port may be located at the charging port 102.

[0049] The charging door device 10 may include a charging door panel 200. The charging door panel 200 can open and close the outer side of the housing portion 100. For example, when the charging door panel 200 is open, the charging port located at the charging port 102 can be exposed to the outside.

[0050] For example, the charging door panel 200 can be opened and closed relative to the housing portion 100 by swinging in one direction. For example, the charging door panel 200 can open and close the housing portion 100 in the vertical direction.

[0051] The housing portion 100 may include a port cover portion 110 fixed to an opening area in the vehicle body panel. For example, the port cover portion 110 may form part of the vehicle's outer surface.

[0052] The port cover 110 may be formed in the shape of a plate or a board. For example, the port cover 110 may have two sides. For example, the port cover 110 may have a front face and a rear face. The distance between the front face and the rear face of the port cover 110 may refer to the thickness of the port cover 110.

[0053] The front face of the port cover 110 may face forward or be oriented towards the front. The rear face of the port cover 110 may face backward or be oriented towards the rear. For example, the front face of the port cover 110 may face or be oriented towards the exterior of the vehicle. For example, the rear face of the port cover 110 may face or be oriented towards the interior of the vehicle.

[0054] When the charging door panel 200 is closed, the front face of the port cover 110 can face the charging door panel 200. The rear side of the port cover 110 can be formed on the opposite side of the front face of the port cover 110.

[0055] For example, the material of the port cover 110 can be the same as that of the vehicle body panel. For example, the port cover 110 can be formed of a material containing metal. This ensures the strength of the port cover 110.

[0056] The charging port 102 can be an opening or hole that penetrates the port cover 110. For example, the charging port 102 can penetrate the front face and the rear face of the port cover 110. For example, the charging port 102 can be connected to the front face and the rear face of the port cover 110.

[0057] The outer side of the port cover 110 may be covered by the charging door panel 200. For example, the charging door panel 200 may swing, thereby exposing or obscuring the outer side of the port cover 110. The outer side of the port cover 110 may be the front face of the port cover 110. For example, the charging door panel 200 may obscure the charging port 102 of the housing 100 or expose it to the outside.

[0058] The housing portion 100 may include a port housing portion 120. The port housing portion 120 may be disposed on the inside of the vehicle body. The port housing portion 120 may be coupled to the port cover portion 110. For example, the port housing portion 120 may be connected to or coupled to the inner side of the port cover portion 110. For example, the inner side of the port cover portion 110 may be the rear face of the port cover portion 110.

[0059] For example, the port housing portion 120 may include a lower port housing portion 121. The lower port housing portion 121 may, for example, be connected to or coupled to the inner side of the port cover portion 110. The lower port housing portion 121 may form a space that opens forward.

[0060] A space may be formed between the lower port housing portion 121 and the port cover portion 110. A portion of the components used for charging may be located in the space formed by the lower port housing portion 121 and the port cover portion 110.

[0061] The port housing portion 120 may include an upper port housing portion 125. The upper port housing portion 125 may be shaped to extend upward from the lower port housing portion 121. For example, the upper port housing portion 125 may be connected to the rear (or inner) side of the lower port housing portion 121.

[0062] For example, the upper port housing portion 125 may form a receiving space. For example, the receiving space formed in the upper port housing portion 125 may open rearward. For example, the upper port housing portion 125 may be formed into a recessed shape when viewed from the rear.

[0063] The charging door device 10 may include a linkage connecting member 300. An upper port housing portion 125 may accommodate the linkage connecting member 300. The inner surface of the upper port housing portion 125 may face a receiving space formed therein. The linkage connecting member 300 may face the inner surface of the upper port housing portion 125. The upper port housing portion 125 may form a space for the linkage connecting member 300 to rotate.

[0064] The upper port housing portion 125 may be bent and extended from the lower port housing portion 121. For example, a portion of the upper port housing portion 125 may extend rearwardly from the lower port housing portion 121.

[0065] The upper port housing portion 125 may have a hinge pin engagement hole 125h formed therein. A portion of the front (or outer side) of the upper port housing portion 125 may protrude forward. The hinge pin engagement hole 125h may be located on the protruding front of the upper port housing portion 125. The upper port housing portion 125 as a whole may have a structure in which the hinge pin engagement hole 125h protrudes forward.

[0066] The hinge pin 101 can be rotatably engaged with the hinge pin engagement hole 125h. The connecting rod connecting member 300 can be connected to or engaged with the hinge pin 101. The connecting rod connecting member 300 can be rotatably engaged with the housing portion 100.

[0067] The front face of the upper port housing 125 may include an upper front face 125t. The upper front face 125t may be formed by extending upward based on the hinge pin engagement hole 125h.

[0068] The front face of the upper port housing 125 may include a lower front face 125b. The lower front face 125b may be formed extending downward with reference to the hinge pin engagement hole 125h.

[0069] The front face of the upper port housing portion 125 may face forward-upward direction. For example, the upper front portion 125t of the upper port housing portion 125 may face forward-upward direction. For example, the upper front portion 125t may face the space between the forward direction and the upward direction. For example, the upper front portion 125t may extend backward-upward direction from the hinge pin engagement hole 125h and connect to the upper surface of the upper port housing portion 125.

[0070] The lower front portion 125b of the upper port housing portion 125 may be inclined rearward from the hinge pin engagement hole 125h. For example, the lower front portion 125b may face forward-downward. For example, the lower front portion 125b may face in a direction between forward and downward. For example, the lower front portion 125b may extend backward-downward from the hinge pin engagement hole 125h and connect to or engage with the lower port housing portion 121.

[0071] The upper port housing 125 can accommodate the operating force correction module 400, which will be described later. The housing 100 may include a correction chamber 130. The correction chamber 130 may be arranged on the upper front side 125t of the upper port housing 125.

[0072] The upper front portion 125t can be spaced inward from the body panel at the hinge pin engagement hole 125h. For example, the distance from the body panel to the upper front portion 125t can be greater than the distance from the body panel to the hinge pin engagement hole 125h.

[0073] When the charging door panel 200 closes the outer casing 100, the body panel and the charging door panel 200 can form a continuously extending outer side of the vehicle.

[0074] The correction chamber 130 may be located further rearward than the hinge pin engagement hole 125h. For example, the distance between the correction chamber 130 and the body panel may be greater than the distance between the hinge pin engagement hole 125h and the body panel. For example, the correction chamber 130 may be arranged further inward toward the body panel than the hinge pin engagement hole 125h.

[0075] For example, the calibration chamber 130 may be spaced apart from the inner side of the vehicle body panel. For example, the vehicle body panel may be used as a heat insulation element. For example, the temperature range of the calibration chamber 130 may be smaller than the temperature range outside the vehicle.

[0076] The charging door panel 200 may include a panel bonding plate 210. The panel bonding plate 210 may be disposed behind the charging door panel 200. The panel bonding plate 210 may face the port cover portion 110.

[0077] Reference Figure 5 and Figure 6 The linkage connection member 300 is rotatable about the hinge pin 101 included in the housing portion 100 as a rotation axis. For example, the linkage connection member 300 may include a linkage rotating portion 301 coupled to the hinge pin 101.

[0078] The connecting rod rotating part 301 can be a component with a hollow cylindrical shape. The hinge pin 101 can be inserted into the interior of the connecting rod rotating part 301. For example, the connecting rod connecting part 300 can rotate in the housing part 100 via the hinge pin 101 inserted into the connecting rod rotating part 301.

[0079] The link connection component 300 may include a link body 310. The link body 310 may extend from or be connected to the link rotation portion 301. For example, the link body 310 may extend from the link rotation portion 301 and reach the link connection end 303.

[0080] The linkage body 310 may include a first linkage 311. The first linkage 311 may extend from a linkage connection end 303 coupled to the charging door panel 200. For example, the first linkage 311 may extend rearward from the linkage connection end 303. For example, the first linkage 311 may extend rearward for the first time from the linkage connection end 303, and then bend upward to form a curved surface for the second extension.

[0081] For example, the first link 311 may be convex rearward. For example, the rear face of the first link 311 may be convex. For example, the front face of the first link 311 may be concave.

[0082] Reference Figure 7 The connecting rod end 303 may face or be attached to the inner side of the charging door panel 200. The connecting rod end 303 may be attached to the panel bonding plate 210 formed on the inner side of the charging door panel 200. The connecting rod end 303 may be a plate-shaped component. The connecting rod end 303 may extend downward from or be attached to the lower end of the first connecting rod 311.

[0083] The connecting rod end 303 can be attached to the rear of the charging door panel 200 via a connecting rod connecting bolt 305. The connecting rod connecting bolt 305 can fasten the connecting rod end 303 to the charging door panel 200. For example, the connecting rod connecting bolt 305 can fasten the connecting rod end 303 to the panel mounting plate 210.

[0084] The connecting rod connecting bolt 305 can be inserted into and engaged in at least one bolt through hole formed on the connecting rod connection end 303. For example, the connecting rod connecting bolt 305 can bolt the panel connecting plate 210 to the connecting rod connection end 303.

[0085] The link body 310 may include a second link 312. The second link 312 may extend from the upper end of the first link 311 and connect to the link rotation portion 301. For example, the front face of the second link 312 may face the rear (or inner) side of the upper front portion 125t. For example, the second link 312 may be arranged parallel to the upper front portion 125t.

[0086] The connecting rod connection component 300 may include a connecting rod pressure end 320. The connecting rod pressure end 320 may protrude from the connecting rod body 310. The connecting rod pressure end 320 may protrude from the front of the second connecting rod 312. The connecting rod pressure end 320 may face or be directed toward the rear of the upper front portion 125t.

[0087] The connecting rod body 310 may include outer connecting rod ribs 313s. The outer connecting rod ribs 313s may be formed at the rear end of the connecting rod body 310. For example, the outer connecting rod ribs 313s may extend from the connecting rod rotating portion 301 and reach the connecting rod connecting end 303. The outer connecting rod ribs 313s may protrude along both rear ends of the connecting rod body 310. For example, there may be multiple outer connecting rod ribs 313s. For example, there may be a pair of outer connecting rod ribs 313s.

[0088] A pair of outer connecting rod ribs 313s may have a continuous curve extending from the connecting rod connection end 303 to the connecting rod rotating part 301.

[0089] The link body 310 may include an inner link rib 313c. The inner link rib 313c may be formed along the center of the rear end of the link body 310. For example, the inner link rib 313c may be formed between a pair of outer link ribs 313s. For example, the inner link rib 313c may have a continuous curve extending from the link connection end 303 to the link compression end 320.

[0090] The connecting rod pressurizing end 320 may be shaped to protrude from a pair of outer connecting rod ribs 313s and inner connecting rod ribs 313c. For example, the connecting rod pressurizing end 320 may connect a pair of outer connecting rod ribs 313s and inner connecting rod ribs 313c. For example, the connecting rod pressurizing end 320 may extend from the outer ends of a pair of outer connecting rod ribs 313s and the outer ends of inner connecting rod ribs 313c.

[0091] On the other hand, the link body 310 may include a strength-reinforcing rib 313a. The strength-reinforcing rib 313a may connect a pair of outer link ribs 313s and inner link ribs 313c. This increases the strength of the link body 310.

[0092] Reference Figure 8 and Figure 9 An embodiment of the charging door device 10 disclosed herein may include an operating force correction module 400. The operating force correction module 400 is disposed in the outer shell portion 100 constituting the vehicle and may have a spring structure. The operating force correction module 400 can maintain the applied pressure on the charging door panel 200, which is coupled to the linkage connection member 300, within an allowable operating force range.

[0093] The operating force correction module 400 may include a plunger 410. The plunger 410 may be pressurized by the connecting rod pressurizing end 320 of the connecting rod connecting component 300.

[0094] The plunger 410 may include a plunger body 411. The plunger body 411 may be a plate-like shape with a predetermined thickness. For example, the plunger body 411 may be a plate shape with a circular or quadrilateral cross-section. For example, the plunger body 411 may form a front and a rear. The front of the plunger body 411 may face forward or towards the front. The rear of the plunger body 411 may face backward or towards the rear.

[0095] The plunger 410 may include a plunger engagement protrusion 413. The plunger engagement protrusion 413 may be connected to or engaged with the front of the plunger body 411.

[0096] The plunger engagement protrusion 413 may extend forward from the front of the plunger body 411. The plunger engagement protrusion 413 may protrude from the plunger body 411 toward the elastomer placement protrusion 433.

[0097] The plunger engagement protrusion 413 may form an empty space inside. For example, the plunger engagement protrusion 413 may have a hollow cylindrical shape. For example, the plunger engagement protrusion 413 may include an elastomeric engagement rib (not shown) formed along its extended length direction. There may be multiple elastomeric engagement ribs. Multiple elastomeric engagement ribs may be arranged at predetermined intervals along the outer periphery of the plunger engagement protrusion.

[0098] The plunger 410 may include a pressure protrusion 415. The pressure protrusion 415 may extend rearward from the rear of the plunger body 411. The pressure protrusion 415 may protrude from the plunger body 411 toward the inside of the housing portion 100. The pressure protrusion 415 may protrude from the plunger body 411 toward the connecting rod pressure end 320.

[0099] A hollow space can be formed inside the plunger engagement protrusion 413. For example, the pressure protrusion 415 can have a hollow cylindrical shape. A guide rib (not shown) can be formed on the outer peripheral surface of the pressure protrusion 415. The guide rib can be formed into a protrusion or groove shape along the length direction of the pressure protrusion 415. The guide rib can move along the groove or protrusion shape formed on the port housing portion 120 in a manner corresponding to the shape of the guide rib. Thus, when the plunger 410 moves back and forth along the port housing portion 120, rotation of the plunger 410 can be prevented.

[0100] The operating force correction module 400 may include an elastomer 420. The elastomer 420 may have a helical spring shape. One end of the elastomer 420 may be coupled to a plunger engagement protrusion 413, and the other end may be coupled to a chamber cover 430 coupled to the housing portion 100.

[0101] One end of the elastomer 420 may accommodate the plunger engagement protrusion 413. The other end of the elastomer 420 may be coupled to the chamber cover 430. The plunger engagement protrusion 413 and the plunger body 411 may form a step. For example, the plunger engagement protrusion 413 may have the same center, and the diameter of the plunger engagement protrusion 413 may be smaller than the diameter of the plunger engagement protrusion 414.

[0102] The operating force correction module 400 may include a chamber cover 430.

[0103] The chamber cover 430 may include a cover body 431 and a body core 432 connected to or attached to the cover body 431.

[0104] The cover body 431 can be tightly fitted to the outside of the calibration chamber 130 disposed on the upper port housing portion 125. The cover body 431 can be connected to or coupled to the body core 432. For example, the cover body 431 can extend from the body core 432. The cover body 431 can face the calibration chamber body 131 (see reference). Figure 10 For example, the inner surface of the cover body 431 may contact the correction chamber body 131 (see reference). Figure 10 ).

[0105] The main body core 432 can face the calibration chamber core 132 (see reference). Figure 10 For example, the main body core 432 can contact the correction chamber core 132 (see reference). Figure 10 For example, the inner surface of the main body core 432 can contact the correction chamber core 132 (see reference). Figure 10 ).

[0106] The main core 432 may be connected to the cover body 431. For example, the main core 432 may extend from the cover body 431. For example, the main core 432 may be a part of the cover body 431. For example, the main core 432 may form the central portion of the cover body 431. For example, the main core 432 may be in the shape of a circular plate.

[0107] The chamber cover 430 may include an elastomeric placement protrusion 433. The elastomeric placement protrusion 433 may be formed protruding from the inner side of the body core 432 or the cover body 431. For example, the elastomeric placement protrusion 433 may extend rearward from the rear of the body core 432.

[0108] The chamber cover 430 may include a cover engagement protrusion 435. The cover engagement protrusion 435 may be formed by protruding from the inner side of the cover body 431 based on the elastomer placement protrusion 433.

[0109] The following is for reference Figure 10 and Figure 11 This shows the relationship between the chamber cover 430 and the calibration chamber 130.

[0110] The calibration chamber 130 may be formed on the outer surface of the upper port housing portion 125. For example, the calibration chamber 130 may be formed on the upper front portion 125t of the upper port housing portion 125.

[0111] The calibration chamber 130 may include a calibration chamber body 131. The calibration chamber body 131 may be formed on the upper front portion 125t of the upper port housing portion 125. The calibration chamber body 131 may extend on the outer side of the port housing portion 120. For example, the calibration chamber body 131 may extend on the outer side of the upper port housing portion 125.

[0112] The calibration chamber 130 may include a calibration chamber core 132. The calibration chamber core 132 may be formed in the central portion of the outer surface of the calibration chamber body 131. The calibration chamber core 132 may be formed in a hollow portion connected to the chamber inlet 133. The calibration chamber core 132 may be in a hollow cylindrical shape.

[0113] The calibration chamber 130 may include a chamber inlet 133. The chamber inlet 133 may form an outer opening of the calibration chamber core 132.

[0114] The calibration chamber 130 may include a raised engagement port 135. The raised engagement port 135 may be formed on both sides of the calibration chamber body 131 with the calibration chamber core 132 as the center. An elastomer placement protrusion 433 may correspond to the chamber inlet 133, and a cover engagement protrusion 435 may correspond to the raised engagement port 135. On the other hand, the cover body 431 may be engaged with the outer surface of the calibration chamber body 131 with the calibration chamber core 132 as the center.

[0115] The linkage connecting component 300 is coupled to the hinge pin 101, which is rotatably inserted into the hinge pin engagement port 125h. The linkage connecting component 300 can rotate about the linkage rotating part 301 connected to the hinge pin 101. The linkage connecting component 300 can receive applied pressure from the charging door panel 200 through the linkage connecting end 303. The linkage connecting component 300 can provide applied pressure to the operating force correction module 400 through the linkage applying end 320.

[0116] A user can apply a first pressure to the charging door panel 200 from outside the vehicle. The first pressure applied to the charging door panel 200 can be redirected via a linkage connection member 300. The pressure transmitted by the linkage connection member 300 can be transmitted to the operating force correction module 400. The pressure transmitted to the operating force correction module 400 can be a second pressure.

[0117] For example, the direction of the first applying force and the direction of the second applying force can be different. For example, the direction of the first applying force and the direction of the second applying force can be opposite to each other through the connecting rod connecting member 300.

[0118] For example, refer to Figure 5 When the charging door panel 200 is pressurized toward the vehicle interior, the linkage connecting member 300 can rotate counterclockwise around the linkage rotating part 301. As a result, the linkage pressing end 320 of the linkage connecting member 300 can pressurize the plunger 410 of the operating force correction module 400 arranged in the correction chamber 130 toward the vehicle exterior.

[0119] On the other hand, the operating force management tolerance through the operating force correction module 400 can be 3.75 ± 0.25 kgf. The pressure applied to the operating force correction module 400 can be in the range of 3.5 kgf to 4.0 kgf.

[0120] It will be apparent to those skilled in the art that the present invention may be implemented in other specific forms without departing from the spirit and essential characteristics of the invention. The detailed description above should not be construed as restrictive in all respects, but rather as exemplary. The scope of the invention should be determined by a reasonable interpretation of the appended claims, and all modifications within the equivalent scope of the invention are included within the scope of the invention.
