Detailed Implementation

[0020] The specific embodiments of the present invention will be further described below with reference to the accompanying drawings. Identical components are indicated by the same reference numerals. It should be noted that the terms "front," "rear," "left," "right," "up," and "down" used in the following description refer to directions in the accompanying drawings, while the terms "inner" and "outer" refer to directions toward or away from the geometric center of a specific component, respectively.

[0021] like Figures 1-12 As shown, an embodiment of the present invention provides a charging port cover mechanism, including a port tube 1, a port cover 2, a hinge 3, a pivot shaft 4, and a drive module 5.

[0022] The outer side of the mouth tube 1 has a mouth tube groove 11 for accommodating the mouth cover 2 in the closed state.

[0023] An installation structure 12 is provided on the inner side of the proximal end 1a of the mouth tube 1, and the pivot shaft 4 is installed on the installation structure 12. The proximal end 2a of the mouth cover 2 is connected to the pivot shaft 4 through a hinge 3.

[0024] The drive module 5 is installed on the mounting structure 12 and is used to drive the movement of the cover 2 to open and / or close.

[0025] A locking structure is fitted between the distal end 11b of the mouth tube groove 11 and the distal end 2b of the mouth cover 2. The locking structure includes a telescopic pin 6 and a locking block 7 with a locking groove 71.

[0026] The telescopic pin 6 is telescopically arranged at the distal end of the mouth pipe recess 11 / the mouth cover 2, and the locking block 7 is fixedly arranged at the distal end of the mouth cover 2 / the mouth pipe recess 11.

[0027] When the mouth cover 2 is in the closed state, the end of the telescopic pin 6 extends into the locking recess 71, for keeping the mouth cover 2 in the closed state.

[0028] The charging mouth cover mechanism provided by the application comprises a mouth pipe 1, a mouth cover 2, a hinge 3, a pivot shaft 4, a driving module 5 and the like.

[0029] In the application, for the convenience of description, the end of the mouth cover 2 rotating around the shaft is referred to as the proximal end, and the end away from the shaft is referred to as the distal end, and correspondingly, the mouth pipe 1, the telescopic pin 6 and the like are also described by the proximal end and the distal end.

[0030] The mouth pipe 1 is used for being mounted on the vehicle body. The mouth pipe 1 has a proximal end 1a and a distal end 1b arranged oppositely, and the proximal end 1a and the distal end 1b are arranged oppositely along the front-rear direction of the vehicle body. The inner side of the proximal end 1a is provided with a mounting structure 12, which can be a mounting table, a mounting bracket or the like. The mounting structure 12 can be connected with the vehicle body, and is also used for mounting components such as the pivot shaft 4 and the driving module 5.

[0031] The outer surface of the mouth pipe 1 has a mouth pipe recess 11 recessed inwardly, and the bottom plate of the mouth pipe recess 11 is provided with a through hole for inserting the charging gun to be connected with the charging port of the vehicle body. When the mouth cover 2 is in the closed state, the mouth cover 2 is accommodated in the mouth pipe recess 11.

[0032] The mouth pipe recess 11 is arranged in a substantially rectangular shape, and has a proximal end slot wall 11a and a distal end slot wall 11b arranged oppositely.

[0033] The mouth cover 2 is used for covering the opening of the mouth pipe recess 11 to shield the charging port. The mouth cover 2 has a proximal end 2a and a distal end 2b arranged oppositely. The shape of the mouth cover 2 is shaped along the mouth pipe recess 11, and the size of the mouth cover 2 is slightly smaller than the size of the mouth pipe recess 11, so that the mouth cover 2 can be accommodated in the mouth pipe recess 11, so that the outer surface thereof is substantially flush with the outer surface of the vehicle body when in the closed state.

[0034] The hinge 3 is a goose neck type hinge, and one end thereof is fixedly connected to the inner side of the proximal end 2a of the mouth cover 2. The pivot shaft 4 is mounted to the mounting structure 12, and the other end of the hinge 3 is sleeved with the pivot shaft 4. Therefore, the mouth cover 2 can be rotated to open and close around the pivot shaft 4, as shown in the drawings, the mouth cover 2 is in the position shown in 2-1 when in the closed state, and the mouth cover 2 is in the position shown in 2-2 when in the open state. Figure 4

[0035] ​The driving module 5 is installed on the installation structure 12, which is used to drive the movement of the lid 2 to open and / or close. The driving module 5 can adopt an actuator 51 and / or a torsion spring 52. The actuator 51 and / or the torsion spring 52 can act on the pivot shaft 4 or act on the hinge 3. For example, the pivot shaft 4 can be pivotally installed on the connection structure 12, and one end of the hinge 3 is fixedly sleeved with the pivot shaft 4, so that the actuator 51 and / or the torsion spring 52 can directly act on the pivot shaft 4. For example, the pivot shaft 4 is fixedly installed on the connection structure 12, and one end of the hinge 3 is pivotally sleeved with the pivot shaft 4, so that the actuator 51 and / or the torsion spring 52 can directly act on the hinge 3.

[0036] For example, when only one set of actuator 51 or torsion spring 52 is used, the actuator 51 or torsion spring 52 is used to drive the lid 2 to open, and the user manually closes the lid 2.

[0037] For example, when a combination of an actuator 51 and a torsion spring 52 is used, the actuator 51 can be used to drive the lid 2 to open, and the torsion spring 52 can be used to drive the lid 2 to close. When the actuator 51 drives the lid 2 to open, the action of the torsion spring 52 is overcome. When it is necessary to close, the actuator 51 is closed, and the action of the torsion spring 52 drives the lid 2 to close.

[0038] In the present application, a locking structure is arranged between the distal end of the mouth tube groove 11 and the distal end 2b of the lid 2, which is used to keep the lid 2 in a closed state.

[0039] The locking structure includes a telescopic pin 6 and a locking block 7, and the distal surface of the locking block 7 has a locking groove 71 for the end of the telescopic pin 6 to slide into to achieve locking. The telescopic pin 6 can be composed of a two-stage telescopic structure, or a combination of an elastic member and a sliding pin.

[0040] The head end of the telescopic pin 6 is preferably hemispherical, so as to slide in and out of the locking groove 71.

[0041] The telescopic pin 6 and the locking block 7 have the following two installation modes: The first installation mode: the telescopic pin 6 can be selected to be arranged at the distal end of the mouth tube groove 11, and the locking block 7 can be selected to be arranged at the distal end 2b of the lid 2.

[0042] The second installation mode: the telescopic pin 6 can be selected to be arranged at the distal end 2b of the lid 2, and the locking block 7 can be selected to be arranged at the distal end of the mouth tube groove 11.

[0043] In combination Figures 8-10 As shown, when the lid 2 rotates along the arrow A from the open position to the closed position, the head end of the telescopic pin 6 is gradually compressed from the inside of the locking block 7 and then slides into the locking groove 71, and then extends against the wall surface of the locking groove 71 to lock the lid 2 in the closed position, preventing the lid 2 from being accidentally opened, shaken, etc.

[0044] In combinationFigures 8-10 As shown, when the flap 2 rotates along the arrow B from the closed position to the open position, the head end of the telescopic pin 6 gradually slides out of the locking groove 71 to the inside of the locking block 7, and then remains in the extended state to be compressed and slid into the locking groove 71 again to realize the locking function when the flap 2 is closed.

[0045] In summary, the charging flap mechanism and new energy vehicle provided by the present application can realize the distal end locking function of the flap 2 through the cooperation of the telescopic pin 6 and the locking block 7, simplify the locking structure, have excellent performance, are convenient to install, and are conducive to reducing the cost of products.

[0046] In one embodiment, as shown in Figures 2-4 , Figure 5 and Figures 7-12 , the telescopic pin 6 is connected with the distal end groove wall 11b of the mouth pipe groove 11, the locking block 7 is arranged on the inside of the distal end 2b of the flap 2, and the cross section of the locking groove 71 is a smooth curved surface.

[0047] In this embodiment, the telescopic pin 6 is arranged on the distal end groove wall 11b of the mouth pipe groove 11, and preferably, the telescopic pin 6 passes through the distal end groove wall 11b, a part of which is on the proximal side of the distal end groove wall 11b and a part of which is on the distal side of the distal end groove wall 11b. In this way, a longer telescopic pin 6 can be selected, and the part with sufficient length can be inserted into the locking groove 71, which is conducive to providing locking pressure.

[0048] The locking block 7 is arranged on the inside of the distal end 2b of the flap 2, and preferably, the locking block 7 is arranged integrally with the flap 2, which has high structural strength and is conducive to prolonging the service life. Arranging the locking block 7 on the inside of the distal end 2b of the flap 2 instead of on the edge of the distal end 2b can make the edge of the distal end 2b close to the distal end groove wall 11b, reduce the gap between the two, and provide sufficient space for the mouth pipe groove 11 to accommodate the inwardly protruding locking block 7, which facilitates assembly.

[0049] The cross section of the locking groove 71 along the horizontal direction is a smooth curved surface, which has small friction. During the opening and closing of the flap 2, the smooth curved surface can reduce the resistance to the sliding of the head of the locking pin 61.

[0050] In one embodiment, as shown in Figure 7 , the curved surface is a circular arc surface, and the curvature of the curved surface varies uniformly at different positions, which is conducive to maintaining the stability of the telescopic pin 6 during the telescopic process and preventing sudden elongation and shortening of the telescopic pin 6 and the occurrence of jamming.

[0051] In one embodiment, as shown in Figures 7-12 , the locking block 7 is provided with a guide inclined surface 72 for guiding the telescopic movement of the telescopic pin 6.

[0052] The guide ramp 72 is provided on the inner surface of the locking block 7 and extends gradually inward from the far end of the locking block 7.

[0053] In this embodiment, a guide slope 72 is provided on the inner surface of the locking block 7 near the distal end. The guide slope 72 is configured as follows: The distal end of the guide ramp 72 is located on the distal surface of the locking block 7 and is in contact with the inner edge of the locking groove 71. The guide ramp 72 extends towards the proximal end of the locking block 7 and also towards the inner side of the locking block 7.

[0054] With this configuration, during the opening and closing of the cover 2, the guide ramp 72 can guide the telescopic pin 6 to extend and retract adaptively.

[0055] like Figures 8-10 As shown, during the closing process of the cover 2, the guide ramp 72 contacts the telescopic pin 6, which is in its initial state, as the cover 2 rotates. Then, under the action of the guide ramp 72, the telescopic pin 6 is gradually compressed. As the cover 2 continues to rotate and close, the telescopic pin 6 can be compressed and slide past the far end of the guide ramp 72 and enter the locking groove 71.

[0056] like Figures 11-12 As shown, during the opening of the cover 2, the curved surface of the locking groove 71 compresses the telescopic pin 6. When the telescopic pin 6 reaches the inner edge of the locking groove 71, the force F exerted by the locking groove 71 is decomposed into component forces F0. x and component force F y F x Used for compressing telescopic pin 6,F y The resistance to rotating the cover 2 is as follows: As the cover 2 opens, the telescopic pin 6 slides out of the locking groove 71 and slides to the guide slope 72. At this time, the telescopic pin 6 gradually extends, assisting in opening the cover 2. The force F acting on the guide slope 72 by the telescopic pin 6 is decomposed into component forces F0. x and component force F y F x F is the driving force for the telescopic pin 6 to extend and return to its original position. y It facilitates the opening of the lid 2.

[0057] In one embodiment, such as Figures 7-12 As shown, the distal end of the guide ramp 72 is connected to the locking groove 71 by an arc-shaped transition convex surface 73, which helps the head of the telescopic pin 6 to slide smoothly between the locking groove 71 and the guide ramp 72 without abrupt changes.

[0058] In one embodiment, such as Figures 7-12As shown, the inner side of the locking block 7 is provided with a boss 74, the inner surface 75 of the boss 74 is a plane, and the proximal end of the guide inclined surface 72 is connected to the distal end of the inner surface 75 of the boss 74. When the cover 2 is in the closed state, the inner surface 75 of the boss 74 is close to the bottom plate of the spout recess 11.

[0059] In this embodiment, the inner side of the locking block 7 is provided with an inwardly protruding boss 74, and the inner surface 75 of the boss 74 is a plane. The guide inclined surface 72 extends inwardly from the distal end of the locking block 7 to the distal end of the inner surface 75 of the boss 74. When the cover 2 is in the closed state, the inner surface 75 of the boss 74 is close to the bottom plate of the spout recess 11, providing a positioning function and further preventing the cover 2 in the closed state from shaking.

[0060] In one embodiment, as shown in Figure 1 and Figures 5-6 The telescopic pin 6 includes a sliding pin 61 and a resilient member 62 for driving the sliding pin 61 to extend.

[0061] The distal slot wall 11b of the spout recess 11 is provided with a slot wall through hole 11c, and the sliding pin 61 can slide through the slot wall through hole 11c. The resilient member 62 is assembled on the distal side of the distal slot wall 11b and connected with the sliding pin 61.

[0062] In this embodiment, the telescopic pin 6 adopts the combination of the sliding pin 61 and the resilient member 62.

[0063] The distal slot wall 11b of the spout recess 11 is provided with a slot wall through hole 11c for the sliding pin 61 to pass through. The sliding pin 61 passes through the slot wall through hole 11c in a gap, and can slide linearly relative to the slot wall through hole 11c.

[0064] The resilient member 62 is assembled on the distal side of the distal slot wall 11b and connected with the sliding pin 61. The resilient member 62 can be a spring, which is used to drive the sliding pin 61 to slide towards the proximal side to extend into the spout recess 11, so as to be able to extend into the locking recess 71 to reach the root of the locking recess 71.

[0065] In one embodiment, as shown in Figure 1 and Figures 5-6 The distal side of the distal slot wall 11b is provided with a guide plate 13 with a guide hole 131, and the distal side of the guide plate 13 is provided with a fixing seat 14.

[0066] The proximal end of the sliding pin 61 is connected with a stop ring 611, and the sliding pin 61 passes through the guide hole 131.

[0067] The stop ring 611 is on the proximal side of the guide plate 13 and can be blocked by the guide plate 13.

[0068] The proximal end of the elastic member 62 is connected with the fixing base 14, and the distal end of the elastic member 62 is connected with the sliding pin 61.

[0069] In the embodiment, a guide plate 13 is fixedly installed at the distal side of the distal slot wall 11b, and has a guide hole 131. The guide hole 131 is coaxially arranged with the slot wall through hole 11c, and the hole diameter is substantially equal.

[0070] The fixing base 14 is fixedly installed at the distal side of the guide plate 13, and the proximal side of the fixing base 14 is provided with a mounting slot for mounting the proximal end of the elastic member 62.

[0071] The proximal end of the sliding pin 61 is connected with a stop ring 611, and the size of the stop ring 611 is greater than the hole diameter of the guide hole 131, so that the stop ring 611 can be blocked by the guide plate 13.

[0072] During assembly, the stop ring 611 is at the proximal side of the guide plate 13, and the sliding pin 61 passes through the guide hole 131 and the slot wall through hole 11c in sequence. The proximal end of the elastic member 62 is mounted in the mounting slot of the fixing base 14, and the distal end of the elastic member 62 is connected with the proximal end of the sliding pin 61.

[0073] When the sliding pin 61 is in the initial state, the elastic member 62 is in the elongated state, the head end of the sliding pin 61 protrudes from the slot wall through hole 11c, and the stop ring 611 is blocked by the guide plate 13 at the distal side, so that the positioning is realized.

[0074] In one of the embodiments, as shown in Figure 5 the center of the sliding pin 61 has a mounting blind hole 612, and the opening of the mounting blind hole 612 is at the proximal end of the sliding pin 61. The distal end of the elastic member 62 extends into the mounting blind hole 612 and is connected to the distal end of the mounting blind hole 612.

[0075] In the embodiment, in order to improve the assembly stability of the elastic member 62 and the sliding pin 61, the mounting blind hole 612 is arranged in the center of the sliding pin 61, the opening of the mounting blind hole 612 is on the proximal end surface of the sliding pin 61, the distal end of the mounting blind hole 612 extends to the distal end of the sliding pin 61 and is closed. The distal end of the elastic member 62 extends into the mounting blind hole 612 and is connected to the distal end of the mounting blind hole 612.

[0076] By such arrangement, not only the assembly stability of the elastic member 62 and the sliding pin 61 is improved, but also the sliding pin 61 can be stably driven to slide, and a longer elastic member 62 can be selected to provide a greater elastic force, so that the sliding pin 61 can be tightly pressed against the wall surface of the locking groove 71, and the locking ability is improved.
