Description

Technical Field

[0001] The present invention relates to the technical field of automotive parts, and in particular to a fast and slow charging linkage cover system for a vehicle charging port. Background Art

[0002] New energy vehicles refer to vehicles that use unconventional vehicle fuels as the power source (or use conventional vehicle fuels and adopt new in-vehicle power devices), and integrate advanced technologies in the power control and drive aspects of the vehicle to form vehicles with advanced technical principles, new technologies, and new structures. New energy vehicles can also be called electric vehicles, which need to be charged to the charging battery irregularly.

[0003] The existing charging methods for new energy vehicles are mainly fast charging methods and slow charging methods. According to national standards, fast charging sockets and slow charging sockets cannot be shared. Therefore, most pure electric vehicles are respectively designed with fast charging ports and slow charging ports on the vehicle body.

[0004] For example, in the invention patent document CN112407068A previously applied by the applicant, it discloses a charging port system for a new energy vehicle, which is arranged on the vehicle body of the new energy vehicle and includes: a charging area component formed on the vehicle body, and the inner side of the charging area component is communicated with the inside of the vehicle body; a fast charging interface arranged in the charging area component for adapting to a fast charging device; a slow charging interface arranged in the charging area component for adapting to a slow charging device; and further includes: a mobile shielding mechanism capable of shielding one of the fast charging interface and the slow charging interface, so that the shielded fast charging interface or slow charging interface is isolated from the inside of the vehicle body.

[0005] It can be seen that in the above-mentioned patent product structures, automobile manufacturers, considering various factors such as cost savings and structural layout, arrange the fast and slow charging ports in the same charging small door. Since only one charging port can be used at the same time, the other charging port needs to be exposed. At this time, in order to solve the problem of the other exposed charging port, the charging seat manufacturer adds sealing covers to the two charging ports. When a certain charging port needs to be used, its sealing cover is removed and the charging gun is inserted. At this time, on the premise that a charging small door is opened and exposed, anyone can operate the charging seat sealing cover. When one is removed for charging, the two sealing covers can also be removed at the same time. Therefore, safety accidents and the risk of spontaneous combustion caused by corrosion are likely to occur. Summary of the Invention

[0036] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0037] Referring to Figures 1 to 11 , a fast and slow charging linkage cover system for a vehicle charging port, comprising a vehicle charging interface assembly 1 and a charging interface cover assembly 2 movably connected to the vehicle charging interface assembly 1. A drive lever arm assembly 3 is provided between the vehicle charging interface assembly 1 and the charging interface cover assembly 2. A fast charging port 4 and a slow charging port 5 are formed on the vehicle charging interface assembly 1.

[0038] It further includes a first sealing cover 6 for closing the fast charging port 4, a second sealing cover 7 for closing the slow charging port 5, and a locking mechanism 8 for locking one of the first sealing cover 6 and the second sealing cover 7 on the charging interface cover assembly 2.

[0039] The above content is the basic solution of the present invention, which makes adjustments and improvements to the shielding unit structure of the existing vehicle charging port. The specific working principle is as follows: When the vehicle does not need to be charged, the charging interface cover assembly 2 is in a closed state relative to the vehicle charging interface assembly 1, and the two are close to each other. At this time, the first sealing cover 6 and the second sealing cover 7 respectively close the fast charging port 4 and the slow charging port 5 at the same time to protect the charging port; when the vehicle needs to be charged, the charging interface cover assembly 2 is driven by the drive lever arm assembly 3 so that the charging interface cover assembly 2 is in an open state relative to the vehicle charging interface assembly 1. When opened, under the action of the locking mechanism 8, one of the first sealing cover 6 and the second sealing cover 7 is locked on the charging interface cover assembly 2 and moves away from the vehicle charging interface assembly 1 together with the charging interface cover assembly 2, and the other of the first sealing cover 6 and the second sealing cover 7 is separated from the locking mechanism 8 so that it continues to remain on the vehicle charging interface assembly 1. Thus, in the open state, the use effect of opening one of the fast charging port 4 and the slow charging port 5 and shielding and protecting the other is achieved.

[0040] In order to realize the locking and unlocking control of the first sealing cover 6 and the second sealing cover 7, this embodiment provides a preferred solution, specifically: the locking mechanism 8 includes a driving device 9, a transmission device, as well as a first locking rod 10 and a second locking rod 11. The driving device 9 forms a transmission cooperation with the first locking rod 10 and the second locking rod 11 respectively through the transmission device. More specifically, the first locking rod 10 has a first locking end 10a and a first driving end 10b, and the second locking rod 11 has a second locking end 11a and a second driving end 11b; the first driving end 10b and the second driving end 11b are respectively in transmission connection with the transmission device; a first locking groove 12 is formed on the first sealing cover 6, and the first locking end 10a can be inserted into the first locking groove 12 to lock the first sealing cover 6 on the charging interface cover assembly 2; a second locking groove 13 is formed on the second sealing cover 7, and the second locking end 11a can be inserted into the second locking groove 13 to lock the second sealing cover 7 on the charging interface cover assembly 2; the first locking groove 12 and the second locking groove 13 have the same opening direction, and the first locking end 10a and the second locking end 11a have different orientations. With the above settings, on the one hand, the first sealing cover 6 and the second sealing cover 7 are respectively locked independently and staggeredly by the first locking rod 10 and the second locking rod 11; on the other hand, through the action of the driving device 9 and the transmission device, the two-way output and linkage control of the first locking rod 10 and the second locking rod 11 are realized.

[0041] The preferred setting of the orientations of the first locking end 10a and the second locking end 11a in the above technical solution is: referring to Figure 11 , the first locking end 10a includes a first locking block 14, and the second locking end 11a includes a second locking block 15. The first locking block 14 and the second locking block 15 are arranged perpendicular to each other. During use, since the first locking rod 10 and the second locking rod 11 belong to a linkage structure, they can always maintain a perpendicular state to each other. When one of them is in the fully released position, the other is exactly in the fully locked position, so that the respective release and locking effects can be more stable and reliable.

[0042] In order to simplify the processing difficulty of parts, the first lock block 14 and the second lock block 15 in the structure of the present invention adopt the same structure, and achieve the effect of linkage and independent operation through fine-tuning of the installation method. Specifically: a first fixing groove 16 is provided in the first lock block 14, a first orientation hole 17 is provided on the periphery of the first fixing groove 16, a first fixing block 18 is inserted into the first fixing groove 16, and the first fixing block 18 and the first orientation hole 17 are fixed together by a first bolt 19; a second fixing groove 20 is provided in the second lock block 15, a second orientation hole 21 is provided on the periphery of the second fixing groove 20, a second fixing block 22 is inserted into the second fixing groove 20, and the second fixing block 22 and the second orientation hole 21 are fixed together by a second bolt 23; the first orientation hole 17 and the second orientation hole 21 have different orientations.

[0043] The preferred setting of the transmission device in the above technical solution is: the transmission device includes an output gear 24 connected to the output end of the driving device 9, an input gear 25 meshing with the output gear 24, an output shaft 26 passing through the input gear 25 and rotating synchronously with the input gear 25, a first output worm 27 and a second output worm 28 sleeved on both ends of the output shaft 26, a first gear shaft 29 meshing with the first output worm and drivingly connected to the first lock rod 10, and a second gear shaft 30 meshing with the second output worm and drivingly connected to the second lock rod 11. Among them, the driving device 9 is preferably a motor. When in use, a single driving device 9 drives the output shaft 26 to rotate through the meshing cooperation of the output gear 24 and the input gear 25. At the same time, the first output worm 27 and the second output worm 28 at both ends of the output shaft 26 also rotate synchronously with the output shaft 26, and then the power is output to the first gear shaft 29 and the second gear shaft 30 respectively. At this time, the power splitting has been completed, and the originally single-input power is changed to double-output power, and finally the first lock rod 10 and the second lock rod 11 are driven to operate simultaneously to realize the independent control of the first sealing cover 6 and the second sealing cover 7.

[0044] In this embodiment, transmission grooves 31 are provided in both the first lock rod 10 and the second lock rod 11, the first gear shaft 29 and the second gear shaft 30 are respectively inserted into the corresponding transmission grooves 31, and spline teeth 32 are provided on both the first gear shaft 29 and the second gear shaft 30. Through the setting of the spline teeth 32, the cooperation between the transmission device and the first lock rod 10 and the second lock rod 11 is made more compact and reliable.

[0045] Since the locking mechanism 8 also includes multiple parts, and they need to cooperate with each other during use to ensure normal operation, if the installation position is relatively exposed, it is easy to be disturbed by the outside world and cause abnormal operation, increased wear and tear of parts, and high failure rate. In order to solve the above defects, the charging interface cover assembly 2 is provided with a receiving cavity 33 for accommodating the locking mechanism 8. Through the reasonable layout of the structure of the existing component (charging interface cover assembly 2), the receiving cavity 33 is formed, which can not only provide installation space for the locking mechanism 8, but also protect the various components of the locking mechanism 8.

[0046] The main function of the driving lever arm assembly 3 is to drive the charging interface cover assembly 2 so that it can switch between the closed position state, the fast charging open position state and the slow charging open position state relative to the vehicle charging interface assembly 1. In order to make its drive more stable, the driving lever arm assembly 3 has two groups and is respectively located on both sides of the vehicle charging interface assembly 1, and each group of driving lever arm assemblies 3 includes an active lever arm 34 and a driven lever arm 35; one end of the active lever arm 34 is connected to the external driver (not shown in the figure), and the other end is connected to the charging interface cover assembly 2; one end of the driven lever arm 35 is connected to the vehicle charging interface assembly 1, and the other end is connected to the charging interface cover assembly 2.

[0047] More specifically, the active lever arm 34 is located below the driven lever arm 35, a transmission guide groove 36 is provided on the active lever arm 34, a wedge block 37 is protruded from the lower end of the driven lever arm 35, and the wedge block 37 is inserted into the transmission guide groove 36, so that the active lever arm 34 drives the driven lever arm 35 to move together, so that the active lever arm 34 and the driven lever arm 35 can be installed in a more stable manner to run on a predetermined trajectory.

[0048] The present invention provides a fast-and-slow charging linkage cover system of a vehicle charging port with a new structure. The charging interface cover plate assembly 2 is in a closed position state, a fast-charging open position state and a slow-charging open position state relative to the vehicle charging interface assembly 1. The specific working principle is as follows:

[0049] 1. Closed position state: refer to Figures 1 to 2 When the corresponding vehicle does not need to be charged, the charging interface cover assembly 2 is in a closed state relative to the vehicle charging interface assembly 1, and the two are close to each other. At this time, the first sealing cover 6 and the second sealing cover 7 respectively close the fast charging port 4 and the slow charging port 5 at the same time to protect the charging port.

[0050] 2. Fast charging open position status: refer to Figures 3 to 4When the vehicle needs to be charged and the fast charging mode is matched, the charging interface cover assembly 2 is driven by the drive rod arm assembly 3 so that the charging interface cover assembly 2 is in an open state relative to the vehicle charging interface assembly 1. When opened, the first sealing cover 6 is locked by the locking mechanism 8 and the second sealing cover 7 is released, so that the first sealing cover 6 in it is locked on the charging interface cover assembly 2 and moves away from the vehicle charging interface assembly 1 together with the charging interface cover assembly 2. The second sealing cover 7 is disengaged from the locking mechanism 8 to keep itself on the vehicle charging interface assembly 1 continuously. Furthermore, in the open state, the fast charging port 4 can be opened for use, and the slow charging port 5 can be shielded and protected to achieve the use effect.

[0051] III. Slow charging open position state: Refer to Figures 5 to 6 When the vehicle needs to be charged and the slow charging mode is matched, the charging interface cover assembly 2 is driven by the drive rod arm assembly 3 so that the charging interface cover assembly 2 is in an open state relative to the vehicle charging interface assembly 1. When opened, the second sealing cover 7 is locked by the locking mechanism 8 and the first sealing cover 6 is released, so that the second sealing cover 7 in it is locked on the charging interface cover assembly 2 and moves away from the vehicle charging interface assembly 1 together with the charging interface cover assembly 2. The first sealing cover 6 is disengaged from the locking mechanism 8 to keep itself on the vehicle charging interface assembly 1 continuously. Furthermore, in the open state, the slow charging port 5 can be opened for use, and the fast charging port 4 can be shielded and protected to achieve the use effect.

[0052] The above is only a preferred embodiment of the present invention, and does not impose any limitation on the present invention. Any simple modification, change, and equivalent structural change made to the above embodiments according to the technical essence of the invention still fall within the protection scope of the technical solution of the present invention.
