And the upper side of the flip cover assembly 100 in FIG. 1A is defined as the upper side, and the other end opposite to the upper side is defined as the lower side. FIG. 1A The flip cover 110 in the flip cover assembly 100 in

[0052] As shown in FIG. 1B-1D , the flip cover assembly 100 comprises a base 101, a flip cover 110 and a flip cover actuating assembly 180 configured to actuate the flip cover 110. The flip cover actuating assembly 180 comprises a power source 150, a locking device 120, a hinge device 105, a driving shaft 118 and a driving piece 108. Among them, the base 101 is used to be fixedly installed on the vehicle body, the flip cover 110 is connected to the base 101 through the hinge device 105, and the hinge device 105 is configured to enable the flip cover 110 to move to an open position or a closed position relative to the base 101, so as to open the container cavity 167 of the base 101 to expose the oil filler or charging port 109 in the container cavity 167 or close the container cavity 167 of the base 101 to close the oil filler or charging port 109 in the container cavity 167. The locking device 120 is connected to the lower side of the base 101 and is configured to be movable in the front-rear direction to lock or release the flip cover 110. The power source 150 is connected to the front side of the base 101. The driving shaft 118 is connected between the power source 150 and the hinge device 105 to provide driving force of the power source 150 to the hinge device 105 through the driving shaft 118. The driving piece 108 is arranged on the driving shaft 118 and rotates with the rotation of the driving shaft 118, and the driving piece 108 can drive the locking device 120 to move in the front-rear direction.

[0053] Specifically, in this embodiment, the hinge device 105 includes two pairs of hinge arms 151a and 151b symmetrically arranged front and rear, with the first pair of hinge arms 151a positioned in front of the second pair of hinge arms 151b. The base 101, the flip cover 110, and the hinge arms 151a and 151b form a roughly parallel four-bar linkage, allowing the flip cover 110 to move upwards or downwards to an open or closed position while remaining roughly parallel to the base 101. In the hinge device 105, the first pair of hinge arms 151a includes a hinge arm 114a and a hinge arm 115a, and the second pair of hinge arms 151b also includes a hinge arm 114b and a hinge arm 115b. Hinged arms 114a and 114b have connecting portions 107a and 107b and receiving portions 117a and 117b, and hinged arms 115a and 115b also have connecting portions 106a and 106b and receiving portions 116a and 116b. Hinged arms 114a and 114b and hinged arms 115a and 115b are pivotally connected to the flip cover 110 via their respective connecting portions 107a and 107b and connecting portions 106a and 106b, and are pivotally connected to the base 101 via their respective receiving portions 117a and 117b and receiving portions 116a and 116b. The hinge mechanism 105 is configured to support the movement of the flip cover 110 relative to the base 101 through the movement of the hinge mechanism 105 relative to the base 101. This parallel four-bar linkage enables the flip cover 110 to open or close more stably and reliably. In some other embodiments, the hinge device may consist of only a pair of hinge arms for forming a parallelogram mechanism. And in still other embodiments, the hinge device may not be used to form a parallelogram mechanism, but rather configured to drive the flip cover 110 to rotate relative to the base 101 to open or close the flip cover assembly 100. The specific structure of the hinge device 105 will be described later in conjunction with... FIG. 2B Detailed explanation.

[0054] Still as FIG. 1B-1D As shown, the locking device 120 is provided with a locking pin 122, and the inner surface of the lower side of the flip cover 110 is provided with a locking hook 123. The locking device 120 has a locked position and a released position. When the locking device 120 is in its locked position, the flip cover 110 moves to the closed position relative to the base 101, and the locking pin 122 can pass through the base 101 and engage with the locking hook 123 on the flip cover 110. When the locking device 120 is in its released position, the flip cover 110 is released, the locking pin 122 disengages from the locking hook 123 on the flip cover 110, and the flip cover 110 can be driven by the hinge device 105 to move to its open position. In the embodiments of this application, the direction of movement of the locking device 120 is consistent with the axial direction of the drive shaft 118.

[0055] The drive shaft 118 is located at the lower side and the front corner of the base 101, and one side of the drive shaft 118 is connected to the power source 150, and the opposite side of the drive shaft 118 is provided with a fitting portion 113. The fitting portion 113 of the drive shaft 118 is used to pass through the base 101 and be connected to the hinge arm 115a on the front side. In the embodiment, the hinge arm 115a is sleeved on the fitting portion 113 of the drive shaft 118 through the receiving portion 116a of the hinge arm 115a, so that the driving force of the power source 150 can be provided to the hinge device 105 through the drive shaft 118. In some other embodiments, the fitting portion 113 of the drive shaft 118 can also be connected to the receiving portion of the other hinge arm.

[0056] The driving part 108 is arranged on the middle part of the drive shaft 118 close to the side of the power source 150. With the rotation of the drive shaft 118, the driving part 449 (see FIG. 4A-4C ) on the driving part 108 can be in contact with or away from the driven end 121 of the locking device 120, so that the locking device 120 can move in the front and back directions. The specific structure of the drive shaft 118 and the driving part 108 will be described in detail later. FIG. 4A-4C

[0057] FIG. 2A and FIG. 2B The specific structure of the flip cover 110 is shown, wherein FIG. 2A a perspective view of the flip cover 110 is shown, FIG. 2B a perspective view of the flip cover 110 and the hinge device 105 is shown, which is used to show the structure of the inner side of the flip cover 110 and the hinge device 105 and the connection relationship between the flip cover 110 and the hinge device 105. As FIG. 2A shown, the outer contour shape of the flip cover 110 is roughly matched with the outer contour of the entrance of the cavity 167 of the base 101, the lower middle part of the inner surface of the flip cover 110 is used to arrange the locking hook 123, and the upper side of the inner surface of the flip cover 110 is used to be connected with the connecting portion of each pair of hinge arms 151. The locking hook 123 extends from the inner surface of the flip cover 110 towards the inside, and the locking hole 235 is arranged on the locking hook 123, and the locking hole 235 extends through the locking hook 123 in the front and back directions. Therefore, when the locking device 120 moves in the front and back directions, the locking hole 235 can receive the locking pin 122 on the locking device 120. The bottom of the locking hook 123 has a slope 232 which is formed by being inclined downward from the upper surface of the locking hook 123.

[0058] As FIG. 2B shown, in the first pair of hinge arms 151a, the hinge arm 114a is located at the lower side of the hinge arm 115a, the connecting portion 107a of the hinge arm 114a is hinged to the inner surface of the flip cover 110 through the shaft 226a, and the receiving portion 117a of the hinge arm 114a is hinged to the base 101 through the shaft 203a (see FIG. 3A ​The connecting portion 106a of the hinge arm 115a is hingedly connected to the inner surface of the cover 110 by a shaft 225a, and the shaft 225a is located on the upper side of the shaft 226a. The receiving portion 116a of the hinge arm 115a is internally provided with a shaft hole 244 extending in the front-rear direction, the shaft hole 244 is sleeved on the drive shaft 118 and is rotatably connected to the base 101 by the drive shaft 118. In the embodiment of the present application, at least one protrusion cavity 246 is further provided in the receiving portion 116a and communicates with the shaft hole 244, and the protrusion cavity 246 is formed by extending radially outward from the hole wall of the shaft hole 244. As a specific example, four protrusion cavities 246 are uniformly arranged on the circumference of the shaft hole 244. The protrusion cavities 246 cooperate with the shaft drive protrusions 448 on the drive shaft 118 to form an engagement structure 440 (see FIG. 4A-4C ), so that the rotation of the drive shaft 118 can drive the hinge arm 115a to rotate. The specific cooperation relationship of the engagement structure 440 will be described in detail later in combination with FIG. 4C .

[0059] The structure of the second pair of hinge arms 151b is similar to that of the first pair of hinge arms 151a, and in the second pair of hinge arms 151b, the hinge arm 114b is located on the lower side of the hinge arm 115b. The connecting portions of the hinge arm 114b and the hinge arm 115b are hingedly connected to the inner surface of the cover 110 by the shaft 226b and the shaft 225b. And the receiving portion of the hinge arm 114b is hingedly connected to the base 101 by the shaft 203b. Different from the first pair of hinge arms 151a, the receiving portion of the hinge arm 115b is hingedly connected to the base 101 by the shaft 204b.

[0060] In the embodiment, the shaft 226a is further provided with an elastic mechanism such as a torsional spring 228a, and the shaft 225a is further provided with a damper 227a. Through the elastic mechanism and the damper, the cover 110 can move more stably, and can be kept in the open position. Similarly, the shaft 226b and the shaft 225b are also provided with an elastic mechanism and a damper (see FIG. 3C ).

[0061] When the cover 110 moves from the closed position to the open position, the drive shaft 118 first drives the receiving portion 117a of the hinge arm 115a to rotate downward around the axis of the drive shaft 118. Under the action of the damper 227a, the rotation of the hinge arm 115a can stably drive the cover 110 to move, and in turn drive the receiving portions of other hinge arms to rotate downward around their respective axes. Until the hinge arm 114a and the hinge arm 114b abut against the cavity edge of the base 101, so that each hinge arm cannot continue to rotate, thereby the cover 110 reaches the open position.

[0062] When the lid 110 moves from the open position to the closed position, the drive shaft 118 first drives the receiving portion of the hinge arm 115a to rotate upward around the axis of the drive shaft 118, and then drives the lid 110 to move through the rotation of the hinge arm 115a, and further drives the other hinge arms to move upward. Until the lid 110 is closed on the entrance edge of the cavity 167 of the base 101, the lid 110 reaches the closed position, and the hinge arms cannot continue to rotate.

[0063] In the embodiment of the application, the drive shaft 118 is only connected with the hinge arm 115a, so only the hinge arm 115a is the driving arm, and the other hinge arms are driven arms. When the hinge arm 115a is driven to rotate by the drive shaft 118, the lid 110 is driven to move, and then the other hinge arms are driven to rotate through the movement of the lid 110. As an example, the shafts 203a, 203b and 204b are fixedly connected to the base 101, and the corresponding hinge arms can rotate around the axis of the shaft at one end of the receiving portion of the hinge arms with respect to the corresponding shaft. The shafts 225a, 226a, 225b and 226b are rotatably connected to the lid 110, which can make the corresponding hinge arms rotate around the axis of the shaft at one end of the connecting portion of the hinge arms with respect to the shafts, and also can make the shafts rotate with respect to the lid 110. However, under the action of the torsion spring and the damper, the rotation of the shafts with respect to the lid 110 can be limited. In other examples, the shafts can be fixedly connected with the corresponding hinge arms, and not fixedly connected with the base 101, so that the hinge arms can rotate around the axis of the shaft with the shaft.

[0064] FIG. 3A-3C The specific structure of the base 101 is shown, wherein FIG. 3A The structure of the base 101 is shown at the angle, which is used to show the components in the cavity 167 of the base 101; FIG. 1B The structure of the base 101 is shown at the angle, which is used to show the components in the cavity 167 of the base 101; FIG. 3B The structure outside the cavity 167 of the base 101 is shown; FIG. 3C The structure of the hinge device 105 connected to the base 101 is shown, which is used to show the connection relationship between the hinge device 105 and the base 101 and the position of the lock hole 302. As FIG. 3A-3C As shown, the base 101 is roughly in the shape of a box, and the cavity 167 is formed in the inside of the base 101. The oil filling port or the charging port 109 is arranged on the bottom 369 of the base 101 and communicates with the cavity 167. The base 101 is used to be installed on the vehicle body, and the cavity 167 faces the outside of the vehicle. Therefore, when the cavity 167 is opened, the oil filling port or the charging port 109 can be exposed.

[0065] As shown, the base 101 is roughly in the shape of a box, and the cavity 167 is formed in the inside of the base 101. The oil filling port or the charging port 109 is arranged on the bottom 369 of the base 101 and communicates with the cavity 167. The base 101 is used to be installed on the vehicle body, and the cavity 167 faces the outside of the vehicle. Therefore, when the cavity 167 is opened, the oil filling port or the charging port 109 can be exposed. FIG. 3AAs shown, the lower side sidewall 371 inside the cavity 167 of the base 101 protrudes into the cavity 167 to form two limiting protrusions 365, and a receiving slot 363 is formed between the two limiting protrusions 365 for receiving the locking hook 123 on the cover 110. At least the rear limiting protrusion 365 is further provided with a lock hole 302 which penetrates the corresponding limiting protrusion 365 along the front-rear direction and penetrates through the base 101, so that the locking pin 122 of the locking device 120 connected outside the base 101 can pass through the lock hole 302. When the cover 110 is in the closed position, the lock hole 302 on the base 101 is aligned with the lock hole 235 on the cover 110, so that the locking pin 122 of the locking device 120 can pass through the lock hole 302 and be inserted into the lock hole 235, thereby locking the cover 110 in the closed position. As known by those skilled in the art, the front limiting protrusion 365 can also be provided with a lock hole 302 at the corresponding position.

[0066] In combination FIG. 3A and FIG. 3C As shown, the first pair of hinge arms 151a and the second pair of hinge arms 151b are respectively hinged on the front and rear sides inside the cavity 167 of the base 101. In the embodiment as shown, the shafts 203a of the first pair of hinge arms 151a and the shafts 203b of the second pair of hinge arms 151b are arranged on the lower side inside the cavity 167, one end of the shafts 203a and the shafts 203b is connected to the front sidewall 374 or the rear sidewall 372 of the base 101, and the other end is connected to the limiting protrusion 365 close to the corresponding side. In this way, the hinge arms 114a and the hinge arms 114b can be rotatably connected (i.e., hinged) to the base 101. The shaft 204b is connected to the lower side of the shaft 203b, one end of the shaft 204b is connected to the rear sidewall 372, and the other end is connected to the support block 368b arranged on the bottom 369 of the base 101, so that the hinge arm 115b can be rotatably connected (i.e., hinged) to the base 101. Symmetrically, the support block 368a is also arranged on the front side of the cavity 167, and the drive shaft 118 can pass through the front sidewall 374 from the outside of the base 101 to rotatably connect the support block 368a. In this way, the hinge arm 115a can also be rotatably connected to the base 101.

[0067] As FIG. 3B shown, the motor clamping groove 311 is arranged outside the front sidewall 374 of the base 101, and the upper side of the power source 150 is clamped in the motor clamping groove 311, and the lower side of the power source 150 is fastened and connected to the base 101 by the fastener 312, so that the power source 150 can be fixed to the front side of the base 101. The front sidewall 374 is further provided with a shaft hole 324, one end of the drive shaft 118 can be connected to the power source 150, and the other end can pass through the front sidewall 374 of the base 101 from the shaft hole 324, enter the cavity 167, and be connected to the hinge arm 115a, so that the driving force of the power source 150 can be transmitted to the hinge arm 115a.

[0068] L-shaped grooves 319a, 319b and 319c and limit blocks 331a, 331b and 331c are provided on the lower side wall 371 and the bottom 369 of the base 101, which are used to be clamped with the locking device 120, so that the locking device 120 can be movably connected with the base 101. In the embodiment, the L-shaped grooves 319a, 319b and 319c can limit the upward or inward movement of the locking device 120, and the limit blocks 331a, 331b and 331c can limit the downward or outward movement of the locking device 120, so that the locking device 120 is connected on the lower side of the base 101 and can only move in the front-back direction. As an example, a fixing column 357 is further provided on the inner side of the L-shaped groove 319b, which is used to be connected with one end of the spring 538 (see FIG. 5B ) in the locking device 120.

[0069] FIG. 4A-FIG. 4C The specific structure of the drive shaft 118 and the driving member 108 is shown, wherein FIG. 4A is a perspective view of the drive shaft 118 and the driving member 108 at the angle shown in FIG. 1B , which is used to illustrate the structure of the drive shaft 118; FIG. 4B and FIG. 4C show the connection relationship of the drive shaft 118, the driving member 108 and the hinge arm 115a, FIG. 4B which is used to illustrate the specific structure of the driving member 108, FIG. 4C which is used to illustrate the matching structure of the drive shaft 118 and the hinge arm 115a.

[0070] As FIG. 4AAs shown, the drive shaft 118 is substantially long columnar, and the drive member 108 is coaxially arranged on the drive shaft 118, and their axial direction is consistent with the front-rear direction. The drive shaft 118 has a connecting portion 462 and an assembling portion 113, which are respectively arranged on both sides of the drive member 108, the connecting portion 462 is used to be connected with the power source 150, and the assembling portion 113 is used to be connected with the hinge arm 115a. As an example, the connecting portion 462 is provided with at least one protrusion 466, and in this embodiment, the protrusion 466 is provided as four. The connecting portion 462 is connected with the power source 150 through the protrusion 466 to receive the driving force of the power source 150, so that the drive shaft 118 can rotate. And the assembling portion 113 is provided with at least one shaft driving protrusion 448, in this embodiment, the number of shaft driving protrusions 448 is the same as the number of protrusion cavities 246 of the receiving portion 116a of the hinge arm 115a, and they are all provided as four and are uniformly arranged along the circumferential direction of the assembling portion 113. The assembling portion 113 of the drive shaft 118 is connected with the receiving portion 116a of the hinge arm 115a through the shaft driving protrusion 448. When the assembling portion 113 of the drive shaft 118 is sleeved in the receiving portion 116a of the hinge arm 115a, the assembling portion 113 is accommodated in the shaft hole 244, and the shaft driving protrusion 448 is accommodated in the corresponding protrusion cavity 246.

[0071] In combination FIG. 4A And FIG. 4C As shown, the shaft driving protrusion 448 and the corresponding protrusion cavity 246 form an engagement structure 440, and in each engagement structure 440, the circumferential dimension of the protrusion cavity 246 is greater than the circumferential dimension of the shaft driving protrusion 448, so that the receiving portion 116a and the assembling portion 113 can be rotationally engaged or rotationally separated. When the receiving portion 116a and the assembling portion 113 are rotationally separated, the drive shaft 118 rotates relative to the hinge arm 115a without driving the hinge arm 115a to rotate; when the receiving portion 116a and the assembling portion 113 are rotationally engaged, the drive shaft 118 can drive the hinge arm 115a to rotate, and in turn drive the hinge device 105 to rotate to open the flip cover 110.

[0072] Specifically, the protrusion cavity 246 has limiting walls 464a and 464b in the circumferential direction. As shown in FIG. 6, the limiting wall 464a is arranged on the side of the protrusion cavity 246 close to the shaft hole 244, and the limiting wall 464b is arranged on the side of the protrusion cavity 246 away from the shaft hole 244. The limiting wall 464a is arranged on the side of the protrusion cavity 246 close to the shaft hole 244, and the limiting wall 464b is arranged on the side of the protrusion cavity 246 away from the shaft hole 244. FIG. 4CIn the indicated state, the shaft drive protrusion 448 abuts against the limiting wall 464b and is spaced a certain distance from the limiting wall 464a. If the shaft drive protrusion 448 rotates clockwise toward the limiting wall 464a in the direction shown by the arrow, the protrusion cavity 246 and the shaft drive protrusion 448 are separated in the rotation direction, that is, the receiving part 116a and the assembly part 113 rotate apart. At this time, the drive shaft 118 will not drive the hinge arm 115a to rotate, but will rotate relative to the hinge arm 115a. When the shaft drive protrusion 448 rotates to abut against the limiting wall 464a and then continues to rotate clockwise, the protrusion cavity 246 and the shaft drive protrusion 448 are engaged in the rotation direction, that is, the receiving part 116a and the assembly part 113 rotate into engagement. At this time, the drive shaft 118 will drive the hinge arm 115a to rotate.

[0073] Those skilled in the art can design the circumferential dimensions of the protruding cavity 246 and the circumferential dimensions of the shaft drive protrusion 448 according to the required range of rotational separation or rotational engagement of the assembly portion of the drive shaft 118 and the receiving portion 116a of the hinge device 105.

[0074] Therefore, in this embodiment, by setting such a joint structure 440, the two functions of the drive shaft 118 not driving or driving the hinge arm 115a to rotate can be achieved simply by rotating the drive shaft 118 within different angular ranges.

[0075] Combination FIG. 4A and FIG. 4B As shown, the drive member 108 is a disk shape with a notch 445 and is integrally formed with the drive shaft 118 so that the drive member 108 and the drive shaft 118 can rotate synchronously. The notch 445 is formed by a radial indentation from the circumferential surface 443 of the drive member 108. The notch 445 forms two corners on the circumferential surface 443 of the drive member 108. One of these corners forms a drive portion 449. The drive portion 449 is used to contact the driven end 121 of the locking device 120 so that as the drive member 108 rotates, the drive portion 449 can drive the locking device 120 to move (see...). FIG. 6B ).

[0076] FIG. 5A-FIG. 5D The specific structure of the locking device 120 is shown, wherein FIG. 5A The locking device 120 is shown in FIG. 1B The three-dimensional structure diagram shown at the angle. FIG. 5B A perspective view of the locking device 120 as viewed from below is shown. FIG. 5C It shows FIG. 5B Front view, FIG. 5D A perspective view of the locking device 120 mounted on the base 101 is shown. FIG. 5A-5CAs shown, the locking device 120 is a long strip-shaped locking rod, which has a head 558, a body 554 and a tail 559 in the length direction. The head 558 is formed by bending the front end of the locking rod upward and then forward, and the head 558 is connected with the locking rod body 554 substantially in parallel. The tail 559 is formed by extending the rear end of the locking rod rearward. Such a shape can make the locking device 120, although arranged on the lower side outside the base 101, the head 558 can extend upward from the front side of the base 101 to contact the driving member 108 on the driving shaft 118.

[0077] The driven end 121 of the locking device 120 is arranged at the head 558, and the driven end 121 has a driven slope 541. In the present embodiment, the driven slope 541 is inclined both forward and downward in the direction from the outer side to the inner side. An engagement surface 542 perpendicular to the length direction of the locking device 120 is also arranged at the end of the driven slope 541. The driven slope 541 is used to contact the driving part 449 of the driving member 108 and be driven by the driving part 449. In some embodiments, the driven slope 541 can also be inclined in other ways, for example, only forward, as long as the driving part 449 can generate a backward force on the driven slope 541 when driving the driven slope 541. The driven slope 541 is also provided with a recess 553 for retaining the position of the driving part 449.

[0078] A post 552 is arranged on the top surface of the locking rod body 554 near the rear side, and the post 552 extends in a direction perpendicular to the length direction of the locking device 120. The locking pin 122 is connected to the post 552 substantially in parallel with the locking rod body 554. Thus, when the locking device 120 moves forward and backward, the locking pin 122 can also move forward to be inserted into the lock hole 235 of the flip cover 110 or move backward to be withdrawn from the lock hole 235. The front end of the locking pin 122 has an inclined slope 534, which cooperates with the slope 232 on the locking hook 123. When the hinge device 105 drives the flip cover 110 to close, in the state that the flip cover 110 is close to the base 101 but not completely closed, the slope 534 of the locking pin 122 contacts the slope 232 of the locking hook 123, and then the locking pin 122 and the locking hook 123 slide along the slopes in opposite directions, so that the locking pin 122 is inserted into the lock hole 235 on the locking hook 123, and the flip cover 110 is completely closed. Thus, closing and locking the flip cover 110 can be almost synchronized.

[0079] The flip cover actuating assembly 180 further comprises a return spring 537 and a return spring 538, which are both connected between the locking device 120 and the base 101. In the present embodiment, both the return spring 537 and the return spring 538 are provided, and those skilled in the art can understand that in other embodiments, only one of the return spring 537 and the return spring 538 can be provided. The return spring 537 is arranged outside the tail 559 of the locking device 120, and the front end thereof abuts against the stand 552, and the rear end thereof is used to abut against the base 101. The return spring 538 is arranged at the bottom of the locking rod body 554 of the locking device 120, and the locking rod body 554 is connected with a fixed column 556, and the rear end of the return spring 538 is connected to the fixed column 556, and the front end is used to be connected to the fixed column 357 on the base 101. Since the base 101 is fixed to the vehicle body, the return spring 537 and the return spring 538 can provide elastic force to the locking device 120.

[0080] As shown in FIG. 5A , the upper side of the locking device 120 is provided with protrusions 539a, 539b and 539c, which are used to cooperate with the L-shaped grooves 319a, 319b and 319c and the limiting blocks 331a, 331b and 331c on the base 101, so as to movably clamp the locking device 120 on the base 101.

[0081] As shown in FIG. 5D , when the locking device 120 is connected to the base 101, the locking device 120 is arranged on the lower side of the base 101 and can move in the front-rear direction. The head 558 of the locking device 120 protrudes from the front side of the base 101 to the upper side, so that the driven end 121 is close to the shaft hole 324 on the base 101. When the drive shaft 118 extends into the base 101 from the shaft hole 324, the driven end 121 can be in contact with the driving piece 108 on the drive shaft 118.

[0082] When the locking device 120 is in the locking position, the driven end 121 of the locking device 120 can be accommodated in the notch 445 of the driving piece 108, and the driving portion 449 of the driving piece 108 can be in contact with the driven inclined surface 541. With the rotation of the driving piece 108, the locking device 120 moves to its release position, the driving portion 449 drives the locking device 120 to move to the rear side, and the return spring 537 and the return spring 538 are compressed. When the locking device 120 moves to the rear side to the driven end 121 out of the notch 445, the locking device 120 reaches its release position, and under the reset force of the return spring 537 and the return spring 538, the abutting surface 542 abuts against the radial surface 461 of the driving piece 108.

[0083] When the driving member 108 is reversely rotated to expose the gap 445 to the driven end 121 of the locking device 120, the locking device 120 is moved to the front side under the restoring force of the restoring spring 537 and the restoring spring 538 until it reaches its locking position. The driving portion 449 of the driving member 108 is moved along the driven slope 541 to the recess 553.

[0084] Thus, during the opening of the cover 110, the locking device 120 is first moved to the releasing position, and then the hinge device 105 opens the cover 110, and the locking device 120 does not affect the opening of the cover 110 during the opening of the cover 110. Therefore, the functions of the locking device 120 to release the cover 110 and the function of the cover 110 to open are implemented at different times and do not interfere with each other. During the closing of the cover 110, the locking device 120 is moved to the locking position, and the closing and locking of the cover 110 are completed synchronously.

[0085] In the embodiment of the present application, a pull rope (not shown in the figure) can also be connected to the locking device 120, which extends into the vehicle interior for the operator to pull to the rear side. In the case where the power source 150 fails and the cover assembly 100 is in the closed and locked state, the operator can manually pull the locking device 120 to the releasing position from the inside of the vehicle, thereby releasing the cover 110 to open the refueling port or charging port 109.

[0086] FIG. 6A-6D The specific structure of the cover assembly 100 is shown when the cover assembly 100 is in the closed state and the locking device 120 is in the locking position. Among them, FIG. 6A The front view of the cover assembly 100 is shown to show the position of the cover 110; FIG. 6B is FIG. 6A The perspective view of the cover assembly 100 is shown in the absence of the base 101 and the power source 150 to show the relative positions of the locking device 120 and the driving member 108; FIG. 6C is FIG. 6B The cooperation relationship diagram of the driving shaft 118, the driving member 108 and the hinge arm 115a is shown in the to show the rotation angle of the driving member 108 and the hinge arm 115a; FIG. 6D is FIG. 6C The enlarged view of the engagement structure 440 is shown in the.

[0087] As FIG. 6A-6DAs shown, the flip cover 110 is in its closed position and covers the base 101 to close the oil filling port or charging port 109. The locking hook 123 of the flip cover 110 is inserted into the receiving slot 363 of the base 101. The locking device 120 is in its locking position, the locking pin 122 is inserted through the locking hole 302 on the base 101 into the locking hole 235 on the locking hook 123 of the flip cover 110 to lock the flip cover 110 in its closed position. The gap 445 of the driving member 108 accommodates the driven end 121 of the locking device 120. At this time, the return springs 537 and 538 are in a compressed state, and the driving portion 449 of the driving member 108 is abutted against and held at the recess 553 of the driven end 121 under the action of the elastic force.

[0088] In the state as shown in FIG. 6A-6D , the fitting portion 113 of the driving shaft 118 is sleeved in the receiving portion 116a of the hinge arm 115a of the hinge device 105, the shaft driving protrusion 448 in the engagement structure 440 abuts against the limiting wall 464b of the protrusion accommodating cavity 246, and is spaced a certain distance from the limiting wall 464a.

[0089] When the driving shaft 118 rotates towards the limiting wall 464a in the direction of J1 (i.e. clockwise rotation in FIG. 6C and FIG. 6D ), the synchronous rotation of the driving member 108 causes the driving portion 449 to move from the recess 553 of the locking device 120 along the driven inclined surface 541, so that the locking device 120 moves to the rear side away from the driving member 108, so that the locking pin 122 on the locking device 120 is detached from the locking hole 235 on the locking hook 123, thereby releasing the flip cover 110 and simultaneously compressing the return springs 537 and 538 on the locking device 120. However, the shaft driving protrusion 448 is separated from the limiting wall 464a upstream of the protrusion accommodating cavity 246 in the rotation direction, so that the driving shaft 118 rotates relative to the hinge arm 115a without driving the hinge arm 115a to rotate. Until the shaft driving protrusion 448 rotates to the position as shown in FIG. 7A-7D .

[0090] FIG. 7A-7D The specific structure of the flip cover assembly 100 is shown when the flip cover assembly 100 is in the closed state, but the locking device 120 is in the released position. Among them, FIG. 7A is a front view of the flip cover assembly 100, which is used to show the position of the flip cover 110; FIG. 7B is FIG. 7A is a perspective view of the flip cover assembly 100 after the base 101 and the power source 150 are omitted, which is used to show the relative position of the locking device 120 and the driving member 108; FIG. 7C is FIG. 7BFigure showing the cooperation of the drive shaft 118, the drive member 108 and the hinge arm 115a, for showing the rotation angle of the drive member 108 and the hinge arm 115a; FIG. 7D is FIG. 7C Figure showing an enlarged view of the engagement structure 440.

[0091] As FIG. 7A-7D shown, the flip cover 110 is still in its closed position and covers the base 101 to close the oil filling port or the charging port 109. The locking hook 123 of the flip cover 110 is still inserted into the receiving slot 363 of the base 101. However, the locking device 120 is in its released position, the locking pin 122 is disengaged from the locking hole 302 on the base 101 and the locking hole 235 on the locking hook 123 of the flip cover 110 to release the flip cover 110. The driving portion 449 of the drive member 108 is disengaged from the driven slope 541 of the locking device 120, the driven end 121 of the locking device 120 is disengaged from the gap 445 of the drive member 108, and the engagement surface 542 at the end of the driven slope 541 abuts against the radial surface 461 of the drive member 108 under the elastic force of the return spring 537 and the return spring 538, so that the locking device 120 cannot move forward and backward.

[0092] In the state as FIG. 7A-7D shown, the shaft driving protrusion 448 of the drive shaft 118 in the engagement structure 440 abuts against the limiting wall 464a of the protrusion cavity 246 and is spaced apart from the limiting wall 464b. When the drive shaft 118 continues to rotate in the direction of J1 (i.e. clockwise rotation in FIG. 7C and FIG. 7D , the drive shaft 118 drives the hinge arm 115a to rotate through the engagement structure 440 by a certain angle, the rotation of the hinge arm 115a drives the flip cover 110 and the other hinge arms of the hinge device 105 to move together, and drives the flip cover 110 to move towards the open position until it reaches the position as FIG. 8A-8D shown, the flip cover 110 reaches its open position.

[0093] Although the drive member 108 rotates synchronously with the drive shaft 118, the rotation angle of the drive shaft 118 is less than 360° (for example, about 150°), and the gap 445 of the drive member 108 is not aligned with the driven end 121 of the locking device 120 again. Therefore, the engagement surface 542 of the locking device 120 remains abutting against the radial surface 461 of the drive member 108, so that the locking device 120 can be kept in its released position during the opening of the flip cover 110.

[0094] FIG. 8A-8D Figure showing the specific structure of the flip cover assembly 100 when the flip cover assembly 100 is in the open state and the locking device 120 is in the released position. Among them, FIG. 8A Figure showing the front view of the flip cover assembly 100, for showing the position of the flip cover 110;FIG. 8B is FIG. 8A is a perspective view of the flip cover assembly 100 without the base 101 and the power source 150, showing the relative positions of the locking device 120 and the driving member 108; FIG. 8C is FIG. 8B is a diagram showing the cooperation of the driving shaft 118, the driving member 108 and the hinge arm 115a, showing the rotation angles of the driving member 108 and the hinge arm 115a; FIG. 8D is FIG. 8C is an enlarged view of the engagement structure 440.

[0095] As shown in FIG. 1 1, the flip cover 110 is in the open position, and the flip cover 110 is away from the base 101 to expose the oil filling port or the charging port 109 on the base 101. The locking hook 123 of the flip cover 110 is also away from the base 101. And the locking device 120 is kept in its released position. FIG. 8A-8D

[0096] In the state shown in FIG. 12, the shaft driving protrusion 448 of the driving shaft 118 in the engagement structure 440 abuts against the limiting wall 464a of the protrusion accommodating cavity 246, and is spaced apart from the limiting wall 464b. When the driving shaft 118 rotates in the direction J2 opposite to the direction J1 (i.e. counterclockwise rotation in FIG. 13) towards the limiting wall 464b, the shaft driving protrusion 448 of the engagement structure 440 and the limiting wall 464b upstream of the protrusion accommodating cavity 246 in the rotation direction rotate from the separated state to the engaged state. After the shaft driving protrusion 448 engages with the limiting wall 464b, the driving shaft 118 drives the hinge arm 115a to rotate, thereby partially closing the flip cover 110, and moving the flip cover 110 to the position shown in FIG. 14. FIG. 8A-8D FIG. 8C and FIG. 8D In the state shown in FIG. 12, the shaft driving protrusion 448 of the driving shaft 118 in the engagement structure 440 abuts against the limiting wall 464a of the protrusion accommodating cavity 246, and is spaced apart from the limiting wall 464b. When the driving shaft 118 rotates in the direction J2 opposite to the direction J1 (i.e. counterclockwise rotation in FIG. 13) towards the limiting wall 464b, the shaft driving protrusion 448 of the engagement structure 440 and the limiting wall 464b upstream of the protrusion accommodating cavity 246 in the rotation direction rotate from the separated state to the engaged state. After the shaft driving protrusion 448 engages with the limiting wall 464b, the driving shaft 118 drives the hinge arm 115a to rotate, thereby partially closing the flip cover 110, and moving the flip cover 110 to the position shown in FIG. 14. FIG. 9A-9D

[0097] When the driving shaft 118 rotates to the position where the gap 445 of the driving member 108 again aligns with the driven end 121 of the locking device 120, the driven end 121 of the locking device 120 moves away from the radial surface 461 of the driving member 108 under the action of the return spring 537 and the return spring 538, and moves towards the gap 445 on the front side and extends into the gap 445. The driving portion 449 of the driving member 108 moves along the driven inclined surface 541 of the locking device 120 again, until it reaches the position shown in FIG. 17. FIG. 9A-9D

[0098] FIG. 9A-9D show the specific structure of the flip cover assembly 100 during the closing process. Among them, FIG. 9A shows the front view of the flip cover assembly 100, showing the position of the flip cover 110; FIG. 9B is FIG. 9A ​​​​The perspective view of the flip cover assembly 100, omitting the base 101 and power source 150, is used to show the relative positions of the locking device 120 and the drive member 108. FIG. 9C yes FIG. 9B A diagram showing the fit between the drive shaft 118, the drive member 108, and the hinge arm 115a is used to illustrate the rotation angles of the drive member 108 and the hinge arm 115a. FIG. 9D yes FIG. 9C Enlarged view of the central joint structure 440.

[0099] like FIG. 9A-9D As shown, although the flip cover 110 has moved towards its closed position, it has not yet reached the closed position, therefore the flip cover assembly 100 is not fully closed. The locking hook 123 of the flip cover 110 is not fully inserted into the receiving slot 363 of the base 101, and the locking hole 235 on the locking hook 123 is not aligned with the locking hole 302 on the base 101. The locking pin 122 of the locking device 120 passes through the locking hole 302 on the base 101, but the inclined surface 534 of the locking pin 122 abuts against the inclined surface 232 at the bottom of the locking hook 123, preventing the locking pin from being inserted into the locking hole 235 of the locking hook 123, and the locking device 120 cannot yet reach the locked position.

[0100] In such FIG. 9A-9D In the indicated state, the shaft drive protrusion 448 of the drive shaft 118 in the engagement structure 440 still abuts against the limiting wall 464a of the protrusion cavity 246. As the drive shaft 118 continues to rotate in the J2 direction, the drive shaft 118 continues to drive the hinge arm 115a to rotate. The rotation of the hinge arm 115a causes the flip cover 110 and the other hinge arms of the hinge device 105 to move together until the flip cover 110 is completely closed. The locking hook 123 of the flip cover 110 continues to be inserted into the receiving groove 363 of the base 101, and the locking pin 122 of the locking device 120 slides along the inclined surface 232 until the lock hole 235 is aligned with the lock hole 302 of the base 101, and the locking pin 122 can pass through the lock hole 302 and be inserted into the lock hole 235. The driving part 449 of the drive member 108 continues to move along the driven inclined surface 541 of the locking device 120 to the recess 553. Thus, the flip cover 110 reaches the position shown in the figure. FIG. 6A-6D At the same time as the closed position shown, the locking device 120 also reaches the position shown. FIG. 6A-6D The lock position is shown.

[0101] The flip cover actuating assembly 180 and the flip cover assembly 100 of the present application can realize the functions of locking or releasing the flip cover 110 and driving the flip cover 110 to open or close the flip cover 110 through one component, i.e. the driving shaft 118 with the driving member 108. And during the process of opening the flip cover 110, the functions of releasing the flip cover 110 and opening the flip cover 110 are realized at different times and do not interfere with each other. During the process of closing the flip cover 110, the functions of locking the flip cover 110 and closing the flip cover 110 are realized at the same time. Compared with the flip cover actuating assembly 180 and the flip cover assembly 100 which need multiple driving components (such as at least two gear driving components) to realize the two functions, the driving shaft 118 of the present application has simple structure, easy assembly and low requirement for machining precision, and can reduce the cost.

[0102] And in the flip cover assembly 100 of the present application, the locking hook 123 of the flip cover 110 is arranged in the middle of the lower side of the flip cover assembly 100, which can better prevent the flip cover 110 from being forcibly opened from the outside of the vehicle in the locked state compared with the locking hook arranged at the corner of the flip cover.

[0103] In addition, in the flip cover assembly 100 of the present application, the locking device 120 is arranged on the lower side of the base 101, and the power source 150 is arranged on the front side of the base 101, which can save the space occupied by the entire flip cover assembly 100 in the vehicle body. Because the locking device 120 needs a certain movement stroke between the locking position and the releasing position. And the length of the lower side wall 371 of the base 101 is greater than the length of the front side wall 374. The present application covers the movement stroke of the locking device 120 by using the length of the lower side wall 371 of the base 101, thereby saving the occupied space of the flip cover assembly 100.

[0104] In the case of failure of the power source 150 caused by, for example, insufficient power of the vehicle battery, the flip cover assembly 100 of the present application can also release the flip cover 110 by manually pulling the locking device 120 by the operator.

[0105] Although the present application will be described with reference to the specific embodiments shown in the drawings, it should be understood that the fuel filler cap or charging port flip cover assembly of the present application can have many variations without departing from the spirit and scope of the present application. Those of ordinary skill in the art will also realize that there are different ways to change the structure in the embodiments disclosed in the present application, which all fall within the spirit and scope of the present application and the claims.
