Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of vehicle charging, in particular to a vehicle charging port structure. BACKGROUND

[0002] New energy electric vehicles are vehicles that use on-board power as power and use electric motors to drive wheels to travel. Such vehicles generally have a cover plate on the vehicle body, which can open or close the charging port, and the charging gun charges the battery in the vehicle through the charging port.

[0003] The existing cover plate generally adopts a flip type or a sliding type structure to open or close the charging port. Since the charging time of an electric vehicle is often long, the cover plate is exposed for a long time when the flip type structure is used, which is easy to get dirty with water and dust, and a short circuit is easy to form when the cover plate is closed. Moreover, when the cover plate is opened, it protrudes relative to the vehicle body, which is easy to scratch and cause safety accidents. While the sliding type structure can solve the shortcomings of the flip type cover plate, it is inconvenient to manually push and pull the cover plate. When an electric push-pull structure is used, there is a certain failure rate of the electric structure. Once the vehicle computer or the driving structure fails, the cover plate cannot be opened, which will cause the vehicle to run out of power and cannot be driven, which will greatly disturb the user.

[0004] Therefore, it is necessary to improve the prior art to overcome the defects in the prior art. SUMMARY

DETAILED DESCRIPTION

[0029] In order to make the above-mentioned objects, features and advantages of the present application more obvious and easy to understand, the specific embodiments of the present application are described in detail below with reference to the drawings. It can be understood that the specific embodiments described herein are only used to explain the present application, but not to limit the present application. In addition, it should be noted that, in order to facilitate the description, only the parts related to the present application are shown in the drawings, and not all the structures. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor are within the scope of protection of the present application.

[0030] The terms "comprising" and "having" and any variations thereof in the present application are intended to cover non-exclusive inclusion. For example, a process, method, system, product or device including a series of steps or units is not limited to the listed steps or units, but optionally also includes steps or units not listed, or optionally also includes other steps or units inherent to these processes, methods, products or devices.

[0031] Reference to an "embodiment" herein means that a particular feature, structure, or characteristic described in connection with the embodiment can be included in at least one embodiment of the application. The appearances of the phrase in various places in the specification are not necessarily all referring to the same embodiment, nor are they necessarily mutually exclusive of one another. As will be apparent to those of ordinary skill in the art, embodiments described herein can be combined with other embodiments.

[0032] Referring to Figures 1 to 4 As shown, the vehicle charging port structure corresponding to a preferred embodiment of the application comprises: a mounting shell 1 comprising a charging port 121; a cover plate mechanism 2 in sliding connection with the mounting shell 1, the cover plate mechanism 2 having a closed state for driving the charging port 121 to close and an open state for driving the charging port 121 to open; a driving mechanism 3 arranged on the mounting shell 1 and in transmission connection with the cover plate mechanism 2; and an emergency unlocking lever 4 movably arranged on the mounting shell 1 and at least partially located outside the mounting shell 1; wherein the cover plate mechanism 2 moves from the closed state to the open state in response to operation of the emergency unlocking lever 4.

[0033] In the application, the cover plate mechanism 2 is opened or closed in a sliding manner, and the cover plate mechanism 2 is less affected by external factors during charging, so that scratches and safety accidents caused by opening of the cover plate mechanism 2 are unlikely to occur; the cover plate mechanism 2 is automatically opened or closed by the driving mechanism 3, so that the opening and closing actions of the cover plate mechanism 2 are more accurate and human errors caused by improper manual operation are prevented; in addition, since the emergency unlocking lever 4 is arranged, when the driving mechanism 3 or the vehicle computer fails and the cover plate mechanism 2 cannot be opened, the cover plate mechanism 2 can be moved from the closed state to the open state by moving the emergency unlocking lever 4, so as to facilitate opening of the charging port 121, thereby improving adaptability in emergency situations and providing a better user experience.

[0034] Further, the mounting shell 1 comprises a shell body 11 and a fixed cover plate 12. The shell body 11 comprises a bottom side 11a and a first side 11b, a second side 11c, a third side 11d and a fourth side 11e arranged on the bottom side 11a in sequence, the first side 11b and the third side 11d are oppositely arranged, and the second side 11c and the fourth side 11e are oppositely arranged. A cavity is formed in the shell body 11, and a partition plate 111 extending to the first side 11b and the third side 11d is arranged in the cavity. The bottom side 11a, the first side 11b, the second side 11c, the third side 11d and the partition plate 111 cooperatively form a charging cavity 112, and the bottom side 11a, the first side 11b, the third side 11d, the fourth side 11e and the partition plate 111 cooperatively form a storage cavity 113. The fixed cover plate 12 is capped on the opening side of the shell body 11 to close the charging cavity 112 and the storage cavity 113. The charging port 121 is arranged at a position of the fixed cover plate 12 corresponding to the charging cavity 112.

[0035] The charging cavity 112 is used to accommodate the charging head 5 of the vehicle, the charging head 5 is arranged towards the charging port 121, the driving mechanism 3 is arranged in the storage cavity 113, and the cover plate mechanism 2 can move back and forth between the charging cavity 112 and the storage cavity 113. The driving mechanism 3 can drive the cover plate mechanism 2 to move from the charging cavity 112 to the storage cavity 113, so that the cover plate mechanism 2 is switched from the closed state to the open state, or the driving mechanism 3 can drive the cover plate mechanism 2 to move from the storage cavity 113 to the charging cavity 112, so that the cover plate mechanism 2 is switched from the open state to the closed state.

[0036] The inner wall of the charging cavity 112 is provided with a first guide groove 114 for guiding the sliding of the cover plate mechanism 2, and the inner wall of the storage cavity 113 is provided with a second guide groove 115 for guiding the sliding of the cover plate mechanism 2, and the cover plate mechanism 2 is respectively connected with the first guide groove 114 and the second guide groove 115. In this embodiment, the number of the first guide groove 114 can be one or two, and is recessed on the first side 11b and / or the third side 11d; the number of the second guide groove 115 can be one or two, and is recessed on the first side 11b and / or the third side 11d.

[0037] The first guide groove 114 and the second guide groove 115 are both arranged obliquely towards the direction away from the charging port 121, so as to ensure that the cover plate mechanism 2 can move towards the inside of the fixed cover plate 12 when the cover plate mechanism 2 is opened, and can smoothly enter the storage cavity 113. Specifically, the first guide groove 114 has a first end 1141 away from the storage cavity 113 and a second end 1142 close to the storage cavity 113, and in the direction from the first end 1141 to the second end 1142, the first guide groove 114 is arranged obliquely towards the direction away from the charging port 121. The second guide groove 115 has a third end 1151 close to the charging cavity 112 and a fourth end 1152 away from the charging cavity 112, and in the direction from the third end 1151 to the fourth end 1152, the second guide groove 115 is arranged obliquely towards the direction away from the charging port 121. When the cover plate mechanism 2 slides to the first end 1141 and the third end 1151, the cover plate mechanism 2 is in the closed state, and when the cover plate mechanism 2 slides to the second end 1142 and the fourth end 1152, the cover plate mechanism 2 is in the open state.

[0038] Preferably, the second guide groove 115 includes a curved section 1153 with a third end 1151 and a linear section 1154 with a fourth end 1152. The curved section 1153 bends from its end connected to the linear section 1154 toward the third end 1151 toward the charging port 121. The linear section 1154 is inclined in the same direction as the first guide groove 114. By providing the curved section 1153, it can block the cover mechanism 2 in the direction from the second side 11c to the fourth side 11e, preventing the cover mechanism 2 from being moved from the closed state to the open state outside the fixed cover 12, thus achieving a self-locking protection function. Therefore, it is difficult for personnel to open the charging port 121 from the outside by moving the cover mechanism 2.

[0039] Furthermore, referring to Figures 2 to 4 , Figures 6 to 8 As shown, the cover plate mechanism 2 includes a sliding frame 21, a traction frame 22 for sliding the sliding frame 21, and a movable cover plate 23 disposed on the sliding frame 21. The sliding frame 21 includes a front portion 211 near the second side 11c and a rear portion 212 near the fourth side 11e. Both the front portion 211 and the rear portion 212 are provided with column feet 213 at positions facing the first guide groove 114 and / or the second guide groove 115, respectively. The column feet 213 are slidably embedded in the first guide groove 114 and the second guide groove 115. When the cover plate mechanism 2 is in the closed state, the column feet 213 are located at the first end 1141 and the third end 1151, respectively. When the cover plate mechanism 2 is in the open state, the column feet 213 are located at the second end 1142 and the fourth end 1152, respectively.

[0040] The traction frame 22 is movably connected to the mounting housing 1 and is positioned between the sliding frame 21 and the drive mechanism 3. The traction frame 22 includes a traction frame body 221 and a rack 222. The traction frame body 221 is located in the receiving cavity 113 and is connected to the rear part 212 of the sliding frame 21. The two sides of the traction frame body 221 extend towards the first side 11b and the third side 11d, respectively. The rack 222 is disposed on the bottom side 11a of the mounting housing 1 and is located near the first side 11b and the third side 11d. The rack 222 is movably connected to the bottom side 11a and can slide in the direction from the second side 11c to the fourth side 11e.

[0041] The rack 222 is fixedly connected to the bottom of the traction frame body 221 and supports the traction frame body 221. The drive mechanism 3 meshes with the rack 222 to drive the rack 222 to slide, thereby driving the traction frame body 221 to move.

[0042] Preferably, the sliding frame 21 is hingedly connected with the traction frame body 221. Since the sliding frame 21 has an angle change during the sliding process, by adopting the above structure, it can ensure that the traction frame 22 smoothly pulls the sliding frame 21. In the embodiment, the rear part 212 of the sliding frame 21 is fixedly provided with a first hinge part 215, the traction frame body 221 is rotatably provided with a second hinge part 2212 at a position corresponding to the first hinge part 215, and the first hinge part 215 and the second hinge part 2212 are rotatably connected through a hinge shaft 216. The second hinge part 2212 has a self-locking state turning to the first hinge part 215 and an unlocking state turning to the second side 11c, and the traction frame body 221 is provided with a resisting part 2213 limiting the second hinge part 2212 to turn to the fourth side 11e. When the cover plate mechanism 2 is in the closed state, the second hinge part 2212 is in the self-locking state, in which state the second hinge part 2212 can limit the sliding frame 21 to move to the receiving cavity 113, and when the movable cover plate 23 is pushed from the outside towards the opening direction of the movable cover plate 23, the second hinge part 2212 will abut against the resisting part 2213 to drive the second hinge part 2212 to remain in the self-locking state, avoiding opening the charging port 121 by pushing the movable cover plate 23 from the outside. When the traction frame body 221 moves to the fourth side 11e, the second hinge part 2212 can turn to the unlocking state under the action of the first hinge part 215 to avoid the sliding frame 21 in the sliding direction of the sliding frame 21, and continue to move the traction frame body 221, which can smoothly pull the sliding frame 21 to the receiving cavity 113. In the embodiment, the number of the first hinge parts 215 is two, and they are respectively located on both sides of the sliding frame 21 in the direction from the first side 11c to the third side 11d. Correspondingly, the number of the second hinge parts 2212 is also two, and they correspond to the first hinge parts 215 one by one.

[0043] However, by adopting the above structure, when the movable cover plate 23 is pressed or pushed from the outside of the cover plate mechanism 2, the sliding frame 21 may move, thereby causing poor reliability of the sliding frame 21. In order to avoid the above situation, the first connecting part 118 is arranged on the second side 11c, and the second connecting part 214 is correspondingly arranged on one side of the front part 211 of the sliding frame 21 towards the second side 11c, and the first connecting part 118 and the second connecting part 214 are embeddedly connected, so that when the cover plate mechanism 2 is in the closed state, it is more closely connected with the mounting shell 1. In addition, by adopting the above structure, when a person presses the movable cover plate 23 from the outside towards the receiving cavity 113, the first connecting part 118 and the second connecting part 214 can also play a blocking role, further improving the reliability of the cover plate mechanism 2. The first connecting part 118 can be a protrusion protruding on the second side 11c, and the second connecting part 214 can be a groove matched with the protrusion; or the first connecting part 118 can be a groove recessed on the second side 11c, and the second connecting part 214 can be a protrusion matched with the groove.

[0044] Preferably, referring to Figure 5 As shown in the figure, in order to improve the reliability of the sliding of the racks 222, the bottom side 11a of the installation shell 1 is provided with a first guide portion 116 which is a groove or a hole and which is adapted to the outer contour of the racks 222 and which extends along the direction from the second side 11c to the fourth side 11e, and the racks 222 are arranged in the first guide portion 116. By arranging the first guide portion 116, the racks 222 can be conveniently assembled, and other guide rail structures do not need to be arranged, thereby effectively reducing the production cost.

[0045] Referring to Figure 6 and Figure 9 As shown in the figure, after the charging port structure is installed on the vehicle, the vehicle shell 6 has a gap 61 which is adapted to the movable cover plate 23, and water or dust from the outside will flow into the vehicle shell 6 along the gap. In order to avoid the above situation, the periphery of the movable cover plate 23 is provided with a ring of sealing members 24 which are fixed on the sliding frame 21, and when the movable cover plate 23 is in the closed state, the sealing members 24 will abut against the inner wall of the vehicle shell 6 and close the gap.

[0046] Further, referring to Figure 6 and Figure 7 As shown in the figure, the driving mechanism 3 comprises a driving member 31 and a gear assembly 32, the gear assembly 32 is drivingly connected with the driving member 31 and the racks 222 respectively, and the driving member 31 can convert the rotary motion of the gear assembly 32 into the linear motion of the racks 222 in the length direction thereof. In the embodiment, the driving member 31 is specifically a rotary motor. By adopting the above structure, the installation space of the driving mechanism 3 can be reduced, and indeed, in other embodiments, when the space is allowed, the driving mechanism 3 can also adopt a screw rod structure and directly connect with the traction frame body 221 to drive the traction frame body 221 to move.

[0047] The gear assembly 32 comprises a driving wheel 321 which is connected with the output end of the driving member 31, a first driven wheel 322, a second driven wheel 323 and a third driven wheel 324, the first driven wheel 322 is engaged between the driving wheel 321 and one of the racks 222, the second driven wheel 323 is engaged with the driving wheel 321, and the third driven wheel 324 is engaged between the second driven wheel 323 and the other one of the racks 222, so that the driving member 31 can drive the two racks 222 to move at the same time. Preferably, the number of teeth of the driving wheel 321 is the same as that of the second driven wheel 323, and the number of teeth of the first driven wheel 322 is the same as that of the third driven wheel 324, so as to ensure that the two racks 222 move at the same speed. Preferably, the diameter of the driving wheel 321 is greater than that of the first driven wheel 322, so as to improve the moving speed of the racks 222 and further improve the opening or closing efficiency.

[0048] Further, the emergency unlocking rod 4 comprises a rod body 41 and a pushing member 42 arranged on the rod body 41. The rod body 41 is arranged on the bottom side 11a of the mounting shell 1 along the direction from the first side 11b to the third side 11d, and the pushing member 42 extends towards the traction frame 22, and pushes the traction frame 22 and drives the sliding frame 21 to move from the curved section 1153 to the linear section 1154 in response to the movement of the rod body 41. In the embodiment, the pushing member 42 can be a pin, a screw rod or the like which is perpendicularly connected to the rod body 41. Preferably, the rod body 41 has a non-circular cross section to avoid rotation around its axis, thereby avoiding deflection of the pushing member 42.

[0049] Referring to Figure 5 As shown in the figure, the bottom side 11a of the mounting shell 1 is provided with a second guide portion 117 which is adapted to the outer contour of the emergency unlocking rod 4, and the second guide portion 117 is a slot or a hole, the second guide portion 117 extends from the third side 11d to the first side 11b, and the emergency unlocking rod 4 is movably arranged in the second guide portion 117 and can be pulled out from the third side 11d.

[0050] Referring to Figure 7 As shown in the figure, the traction frame body 221 is provided with a guide inclined surface 2211 which is in contact with the pushing member 42 at the position corresponding to the pushing member 42, the guide inclined surface 2211 is perpendicular to the bottom side 11a, and the guide inclined surface 2211 is inclined from one side close to the third side 11d to the other side towards the first side 11b. Preferably, the pushing member 42 is located at the middle position of the traction frame body 221 in the direction from the first side 11b to the third side 11d. In this way, the reliability of the pushing member 42 is improved. When the emergency unlocking rod 4 is pulled out, the pushing member 42 can move towards the third side 11d and push the traction frame body 221 to move towards the receiving cavity 113.

[0051] In addition, the emergency unlocking rod 4 further comprises a pulling portion 43 which is located at the end of the rod body 41 close to the third side 11d, and the pulling portion 43 can be a pull ring, the pulling portion 43 is hingedly connected to the end of the rod body 41 and is located outside the second guide portion 117.

[0052] The working process of the present application is as follows: when the vehicle needs to be charged, the charging port 121 is opened by operating the vehicle computer or the corresponding button to send the instruction; the driving member 31 receives the instruction and rotates to drive the gear assembly 32 to move the rack 222 towards the fourth side 11e, the traction frame body 221 connected with the rack 222 pulls the sliding frame 21 to move to the storage cavity 113 under the driving of the rack 222; when the charging port 121 needs to be closed, the charging port 121 is closed by operating the vehicle computer or the corresponding button to send the instruction, the driving member 31 rotates in the opposite direction to drive the gear assembly 32 to move the rack 222 towards the second side 11c, the traction frame body 221 connected with the rack 222 pushes the sliding frame 21 to move to the charging cavity 112 under the driving of the rack 222, and finally closes at the charging port 121; when the charging port 121 cannot be opened electrically due to an emergency, the pulling part 43 is pulled outwards at the third side 11d, the pushing member 42 moves synchronously and pushes the traction frame body 221 to move towards the storage cavity 113 to drive the sliding frame 21 to move away from the curved section 1153, so as to release the locking state of the sliding frame 21, and then the user can completely open the charging port 121 by rotating the movable cover plate 23.

[0053] The above is only the embodiment of the present application, and does not limit the patent scope of the present application, and any equivalent structure or equivalent process transformation using the content of the present application specification and drawings, or direct or indirect application in other related technical fields, are also included in the patent protection scope of the present application.
