Detailed implementation manners
[0032] Now, various exemplary embodiments of the present utility model will be described in detail with reference to the accompanying drawings. It should be noted that: Unless otherwise specifically stated, the relative arrangements of components and steps, numerical expressions, and numerical values set forth in these embodiments do not limit the scope of the present utility model.
[0033] The following description of at least one exemplary embodiment is merely illustrative in nature and in no way serves as a limitation on the present utility model, its application, or its use.
[0034] Technologies, methods, and devices known to those of ordinary skill in the relevant art may not be discussed in detail, but where appropriate, such technologies, methods, and devices should be regarded as part of the specification.
[0035] In all the examples shown and discussed here, any specific value should be construed as merely exemplary and not as a limitation. Therefore, other examples of the exemplary embodiments may have different values.
[0036] According to the first aspect of the present utility model, as Figures 1-11 shown, a dust cover 20 control system is provided, which includes a charging base panel 10, a dust cover 20, a driving device 30, and a control module 70. An AC interface 11 and a DC interface 12 are provided on the charging base panel 10. The driving device 30 is arranged on the charging base panel 10 and is connected to the dust cover 20. The dust cover 20 has a first surface 21 and a second surface 22 which are oppositely arranged. The control module 70 is connected to the driving device 30 and controls the driving device 30 to drive the dust cover 20 to rotate, so that the first surface 21 covers the AC interface 11, or the second surface 22 covers the DC interface 12.
[0037] With the rapid development of new energy vehicles, generally, new energy vehicles are equipped with a DC interface 12 and an AC interface 11. The electric vehicle is charged by connecting a charging gun to the two charging interfaces respectively to realize two charging modes. A dust cover 20 is arranged on the outermost side of each charging interface. In the prior art, when the dust cover 20 is opened, especially for the integrated layout scheme of the charging ports, both charging interfaces will be exposed, resulting in the charging socket being short-circuited due to water ingress, or foreign objects and dust entering, which affects the charging efficiency and cannot effectively protect the charging interfaces. Therefore, it is necessary to set a dust cover 20 at the charging interface position for protection. Generally, two dust covers 20 need to be set for the two charging interfaces, which has a high cost. And when the vehicle owner uses it, the dust cover 20 needs to be manually opened. For the dust cover 20 that is automatically closed by a spring or a torsion spring, the vehicle owner needs to hold the dust cover 20 by hand when inserting the charging gun, and the dust cover 20 automatically flips and buckles before the charging gun is inserted into the charging port, and the operation is complicated.
[0038] The dust cover 20 control system of the present utility model sets only one common dust cover 20 for the AC interface 11 and the DC interface 12 on the charging base panel 10, which reduces the production cost. When leaving the factory, the dust cover 20 defaultly covers one of the charging interfaces. When charging is needed, the control module 70 controls the driving device 30 to drive the dust cover 20 to rotate to expose the charging interface to be plugged and cover the other charging interface, which is convenient for the vehicle owner to insert the charging gun into the charging interface to be used. The operation during charging is simple, and at the same time, it greatly avoids moisture, foreign objects, and dust from entering the other charging interface, thereby affecting the charging efficiency and realizing effective protection of the charging interface.
[0039] In some embodiments, the AC interface 11 and the DC interface 12 respectively protrude to form a first convex ring 111 and a second convex ring 121; a first flange 211 and a second flange 221 respectively protrude on the first surface 21 and the second surface 22. As Figure 4 shown, the first convex ring 111 is sleeved and connected with the first flange 211, or, as Figure 5As shown, the second protruding ring 121 is sleeve-connected to the second flange 221 .
[0040] The first convex ring 111 and the first flange 211 are sleeved and connected to enclose the AC interface 11, or the second convex ring 121 and the second flange 221 are sleeved and connected to enclose the DC interface 12, which greatly prevents moisture, foreign matter and dust from entering the AC interface 11 or the DC interface 12, thereby affecting the charging efficiency, and effectively protects the charging interface.
[0041] In some embodiments, as Figures 6-7 As shown, the end surfaces of the first flange 211 and the second flange 221 are respectively recessed to form a first annular groove 212 and a second annular groove 222 , and the first convex ring 111 is inserted into the first annular groove 212 , or the second convex ring 121 is inserted into the second annular groove 222 .
[0042] The first convex ring 111 is inserted into the first annular groove 212, so that the AC interface 11 and the dust cover 20 are installed tightly and sealed, or the second convex ring 121 is inserted into the second annular groove 222, so that the DC interface 12 and the dust cover 20 are installed tightly and sealed, which greatly prevents moisture, foreign matter and dust from entering the AC interface 11 or the DC interface 12, thereby affecting the charging efficiency, and effectively protects the charging interface.
[0043] In some embodiments, as Figures 6-7 As shown, the first sealing ring 40 and the second sealing ring 50 are respectively arranged in the first annular groove 212 and the second annular groove 222 , and the end surface of the first convex ring 111 abuts against the first sealing ring 40 , or the end surface of the second convex ring 121 abuts against the second sealing ring 50 .
[0044] The first sealing ring 40 plays a sealing role to prevent moisture, foreign matter and dust from entering between the dust cover 20 and the AC interface 11. The second sealing ring 50 plays a sealing role to prevent moisture, foreign matter and dust from entering between the dust cover 20 and the DC interface 12, thereby affecting the charging efficiency, thereby realizing sealing protection of the charging interface.
[0045] In some embodiments, as Figure 3 As shown, a mounting ear 213 is provided on the side of the dust cover 20 , and a rotating shaft 214 is provided on the mounting ear 213 , which is transmission-connected to the driving device 30 . The dust cover 20 rotates under the drive of the rotating shaft 214 .
[0046] The rotating shaft 214 can be integrally formed with the mounting ear 213, or the rotating shaft 214 is detachably connected to the mounting ear 213. The driving device 30 drives the rotation of the rotating shaft 214, and the mounting ear 213 rotates under the drive of the rotating shaft 214, so that the entire dust cover 20 rotates. The overall structure is simple and easy to operate.
[0047] In some embodiments, as Figure 3 shown, the driving device 30 includes a driving motor 31, a motor gear 312 coaxially connected to the output shaft 311 of the driving motor 31, a transmission gear 32, and an output gear 33. The motor gear 312, the transmission gear 32, and the output gear 33 are meshed in sequence, and the central axis 331 of the output gear 33 is coaxially connected to the rotating shaft 214.
[0048] The motor gear 312, the transmission gear 32, and the output gear 33 are meshed in sequence. The multi-stage meshing increases the transmission ratio, improves the transmission performance, realizes variable ratio transmission, reduces vibration and impact, improves the stability and reliability of the transmission, makes the rotation of the dust cover 20 more stable, and the overall control system of the dust cover 20 is not easily damaged during repeated rotation, increasing the service life.
[0049] In some embodiments, as Figure 2 and Figure 9 shown, a mounting seat 14 is provided between the driving device 30 and the mounting ear 213 on the charging base panel 10. The mounting seat 14 is provided with a through clamping hole 141. Blocking portions 215 are provided at both ends of the rotating shaft 214. The diameter of the blocking portions 215 is greater than the diameter of the clamping hole 141. The rotating shaft 214 is rotatably connected in the clamping hole 141, and both end faces of the clamping hole 141 are respectively abutted against the blocking portions 215 at both ends.
[0050] The rotating shaft 214 is rotatably connected in the clamping hole 141, and both end faces of the clamping hole 141 are respectively abutted against the blocking portions 215 at both ends, which can ensure that the rotating shaft 214 is limited in the clamping hole 141, rotates synchronously with the output gear 33 more stably, and also ensures the stable coaxial connection between the two without eccentricity, thereby ensuring the stable rotation of the dust cover 20 and timely and stably opening the charging interface to be used.
[0051] In some embodiments, as Figure 1 shown, the charging base panel 10 is provided with a mounting position 13 with an opening that is shaped like the driving device 30. At least part of the driving device 30 is arranged in the mounting position 13, and a detachable protective cover 60 is buckled on the opening.
[0052] Under the joint protection of the installation position 13 and the protective cover 60, the driving device 30 can prevent damage caused by external bumps. The protective cover 60 can also greatly prevent moisture, foreign objects and dust from entering the driving device 30, thus affecting the operation of the driving device 30, and can also play a guiding role when the driving device 30 is assembled on the charging base panel 10.
[0053] In some embodiments, such as Figure 8 shown, the dust-proof cover 20 is provided with a clamping groove 223 on the side opposite to the installation ear 213. The driving device 30 further includes clamping claws 122 respectively arranged on one side of the AC interface 11 and the DC interface 12 corresponding to the position of the clamping groove 223. When the dust-proof cover 20 closes the AC interface 11 or the DC interface 12, the clamping claws 122 are clamped with the clamping groove 223 to limit the movement of the dust-proof cover 20, and can release the clamping with the clamping groove 223 when the dust-proof cover 20 needs to be opened.
[0054] In some embodiments, such as Figure 10 shown, the control module 70 includes a circuit board 71 and a button 711 on the circuit board 71. The circuit board 71 is integrated with a controller 712. The controller 712 is electrically connected to the driving device 30 through the circuit board 71. According to the control signal transmitted after the button 711 is pressed, the controller 712 controls the driving device 30 to drive the dust-proof cover 20 to cover the AC interface 11 or the DC interface 12.
[0055] When charging is needed, the vehicle owner sends a control signal to the controller 712 by pressing the button 711. The controller 712 controls the driving device 30 to drive and drive the dust-proof cover 20 to rotate according to the control signal, so as to open the correct AC interface 11 or DC interface 12 to be used, ensuring the accuracy of the opening of the charging interface to be used.
[0056] In some embodiments, such as Figure 11 shown, the control module 70 includes a circuit board 71 and a main controller 73. The circuit board 71 is integrated with a sub-controller 74. The sub-controller 74 is electrically connected to the driving device 30 through the circuit board 71. The main controller 73 sends a control signal to the sub-controller 74 through a wireless network. The sub-controller 74 controls the driving device 30 to drive the dust-proof cover 20 to cover the AC interface 11 or the DC interface 12.
[0057] When charging is required, the main controller 73 sends a control signal to the sub-controller 74 through a wireless network. The sub-controller 74 controls the driving device 30 according to the control signal to drive and drive the dust cover 20 to rotate, so as to open the correct AC interface 11 or DC interface 12 to be used, ensuring the accuracy of the charging interface to be used. Moreover, the main controller 73 does not need to be connected to the sub-controller 74 by a wire harness, saving the usage amount of the wire harness, reducing the installation man-hours, reducing the cost of the entire dust cover 20 control system, increasing the technology of the dust cover 20 control system, and improving the competitiveness of the product and the vehicle.
