Each driving mechanism is fixedly arranged relative to the mounting base 1, and each driving mechanism can drive the corresponding protective cover 3 to move to open and close the opening 102 of the corresponding mounting groove 101.

[0055] As a preferred embodiment, two driving mechanisms are disposed on both sides of the mounting base 1, and each driving mechanism includes a motor 4 and a power transmission mechanism, and the power transmission mechanism is transmission-connected between the motor 4 and the protective cover 3, so that the motor 4 can control the protective cover 3 to open the opening 102 through the power transmission mechanism, and can also control the protective cover 3 to close the opening 102.

[0056] Here, the two driving mechanisms are placed on both sides of the mounting base 1 to facilitate the overall layout, and the driving mechanism includes a motor 4 and a power transmission mechanism. The motor 4 can adopt existing standard parts with low cost, and the power transmission mechanism can be used to adjust the rotation speed of the motor 4 to control the rotation speed of the protective cover 3. Specifically, the gear system 5 can adopt the existing reduction gear system 5.

[0057] It should be additionally explained that the motor 4 can be fixedly mounted on the vehicle body 9 , or can be fixedly mounted on the mounting base 1 , but in this case, a bracket for arranging the motor 4 needs to be provided on the mounting base 1 .

[0058] As a preferred embodiment, Figure 2 , Figure 3 , Figure 5 and Figure 6 As shown, the power transmission mechanism includes a gear train 5 and a guide plate 6, wherein a rack 601 is provided on the guide plate 6, the gear train 5 is transmission-connected to the power output end of the motor 4, the gear train 5 is meshed and connected with the rack 601, and the guide plate 6 is connected to the protective cover 3.

A guide structure is provided between the guide plate 6 and the mounting base 1, and the guide structure is used to guide the guide plate 6 to move along a preset trajectory relative to the mounting base 1. The preset trajectory specifically refers to the trajectory formed by the guide groove 602 described below, and the guide plate 6 moves relative to the mounting base 1, which can drive the protective cover 3 to move relative to the mounting base 1.

[0059] In the above structure, the power transmission mechanism includes a gear train 5 and a guide plate 6, wherein the gear train 5 has high transmission reliability and efficiency, and the guide plate 6 can be connected to the protective cover 3, so that the protective cover 3 can be away from the opening 102 after opening to avoid affecting the charging of the charging gun.

[0060] As a preferred embodiment, the cross section of the guide plate 6 is arc-shaped, and the length direction of the rack 601 is consistent with the bending direction of the guide plate 6. Here, the cross section of the guide plate 6 is set to be arc-shaped, and the length direction of the rack 601 is consistent with the bending direction of the guide plate 6, which facilitates the control of the rotation trajectory of the protective cover 3, so that the protective cover 3 can be away from the opening 102 at a greater distance.

[0061] It should be noted here that Figure 6 As shown, the protective cover 3 in this embodiment includes a plate-shaped cover body and an inserting portion 301 formed on one side of the cover body, wherein the inserting portion 301 is cylindrical in shape and is hollow inside, which can reduce weight and save materials.

[0062] When the protective cover 3 blocks the opening 102, the insertion portion 301 can be inserted into the insertion hole of the insertion body 2011 of the charging port 201 to play a sealing role. The protective cover 3 in this embodiment is equivalent to an integrated design of the existing charging port cover and waterproof cover, which can reduce the number of parts and simplify the charging steps.

[0064] Furthermore, each guide plate 6 is provided with a guide structure on both the upper and lower sides, and each guide structure includes a guide column 106 provided on one side of the avoidance opening 105, and a guide groove 602 provided on the guide plate 6. Specifically, the guide plates 6 are provided with a guide groove 602 on both the upper and lower sides, and the length direction of each guide groove 602 is consistent with the bending direction of the guide plate 6. The guide columns 106 on both sides are respectively embedded in the guide groove 602 on the corresponding side, so that the guide plates 6 can be guided to rotate smoothly.

[0065] In the above structure, a clearance opening 105 is provided on the base to facilitate the arrangement of the guide plate 6. Guide structures are provided on both the upper and lower sides of the guide plate 6 to improve the stability of the protective cover 3 during opening. The provided guide structure includes a guide column 106 and a guide groove 602, which has a simple structure and is easy to process.

[0066] As a preferred embodiment, the vehicle-mounted charging device of this embodiment further includes a low-frequency antenna 7, a first lighting lamp 8 and a second lighting lamp 10. Among them, the low-frequency antenna 7 corresponds to the charging socket 2 one by one. For example, in this embodiment, there are two low-frequency antennas 7, and each low-frequency antenna 7 is arranged on the side of the mounting base 1 facing away from the opening 102, and can be fixed to the mounting base 1 by bonding, screwing, etc. In addition, the setting positions of the two low-frequency antennas 7 correspond to the two mounting grooves 101 respectively, so that they can correspond to the two charging sockets 2. The low-frequency antenna 7 set here can be used to communicate with the control element on the charging gun.

[0067] In this embodiment, there is no specific limitation on the number of the first lighting lamps 8 and the second lighting lamps 10. In a preferred embodiment, each mounting groove 101 is provided with a first lighting lamp 8, and each protective cover 3 is provided with a second lighting lamp 10.

[0068] It should be noted that, in order to facilitate the arrangement of the first lighting lamp 8, Figure 4 As shown, a mounting hole 107 is provided on the upper side of each mounting slot 101 , and two first lighting lamps 8 are respectively installed at the two mounting holes 107 .

[0069] When charging with an existing on-board charging device, it is necessary to manually open the cover of the charging port 201 and confirm the charging socket. It is inconvenient to operate when charging with a gun, and it is not easy to find the charging port 201 when the visual conditions are poor. Therefore, a second lighting lamp 10 is set on the protective cover 3, which can conveniently and quickly distinguish the positions of the fast charging socket and the slow charging socket. Specifically, the shapes of the two second lighting lamps 10 can be distinguished. For example, the shapes of the two second lighting lamps 10 can be DC and AC respectively. In addition, other shapes are also feasible.

[0070] As a preferred embodiment, the vehicle-mounted charging device in this embodiment further includes a controller, which is respectively connected to each motor 4, each low-frequency antenna 7, each first lighting lamp 8, and each second lighting lamp 10. Here, the controller may use, for example, a vehicle controller on the vehicle, or may use other existing controllers that are separately provided.

[0071] In specific use, if the vehicle controller determines that the owner wants to charge, the two second lights 10 can be controlled to light up at the same time. When the inductive charging gun enters the receiving range of one of its low-frequency antennas 7, the low-frequency antenna 7 communicates with the controller, and the controller controls the corresponding motor 4 to drive the corresponding protective cover 3 to open, and the second light 10 on the protective cover 3 remains on, and the other second light 10 is turned off.

[0072] When the charging gun is inserted into the corresponding charging socket 202, the second lighting lamp 10 on the corresponding protective cover 3 is turned off, and during the charging process, the corresponding first lighting lamp 8 can be used to display the charging status, for example, red is always on for charging, and green is full. When the charging gun is unplugged and leaves the receiving range of the low-frequency antenna 7, the low-frequency antenna 7 sends a signal to the controller, and the controller controls the corresponding motor 4 to close the protective cover 3, and the first lighting lamp 8 is turned off.

[0073] Here, the first lighting lamp 8 is used to illuminate the installation slot 101, which can enhance the visualization of the charging process. Even in a dark environment, it is convenient to quickly locate the position of the charging socket 2, which is conducive to improving the convenience of charging and saving the owner's charging time. The second lighting lamp 10 is set on the protective cover 3, which is convenient to quickly locate the position of the protective cover even in a dark environment, and can also improve the convenience of charging. During the whole process, the first lighting lamp 8, the second lighting lamp 10 and the protective cover 3 are automatically turned on and off, which is convenient to use.

[0074] As a preferred embodiment, an opening 104 is provided on the lower side wall of each mounting groove 101, and the opening 104 is used for drainage and can also be used for maintenance. Here, by providing a larger opening 104, it can have the functions of drainage and emergency opening and maintenance in case of failure, which can improve the convenience of maintenance and is also beneficial to protecting the vehicle-mounted charging device.

[0075] As a preferred embodiment, each charging socket 2 includes a charging port 201 and a charging slot 202. The charging port 201 includes an inserting body 2011 having an inserting hole, and a baffle 2012 provided at one end of the inserting body 2011. The baffle 2012 is located in the mounting groove 101. The inserting body 2011 passes through the corresponding through hole 103 of the mounting groove 101, and the charging slot 202 is inserted into the inserting hole. The baffle 2012 can be fixed to the mounting base 1, and the fixing method can be, for example, bonding, screwing, etc.

[0076] In the above structure, the charging socket 2 includes a charging port 201 and a charging slot 202. The charging port 201 can facilitate the charging gun to quickly find the insertion position, and can also facilitate the installation of the charging slot 202. It should be noted that in a preferred embodiment, one of the two charging sockets 2 is a fast charging socket 2, and the other is a slow charging socket 2.

[0077] In order to improve the sealing effect, a sealing ring is provided in the insertion hole. When the insertion part 301 is inserted into the insertion hole, the sealing ring can seal the gap between the insertion part 301 and the insertion body 2011 to achieve a better sealing and waterproof effect.

[0078] During charging, when the inductive charging gun enters the receiving and transmitting range of the low-frequency antenna 7, the corresponding charging port 201 cover drives the motor 4 to open the corresponding protective cover 3, and the corresponding first lighting lamp 8 lights up. When the charging gun is pulled out and leaves the receiving and transmitting range of the low-frequency antenna 7, the corresponding motor 4 closes the corresponding protective cover 3, and the corresponding first lighting lamp 8 is turned off after a preset time, for example, 15 seconds.

[0079] The vehicle-mounted charging device of this embodiment has a short production cycle, low development cost, easy installation and disassembly, and is convenient for after-sales maintenance. When applied to vehicles, it can improve the intelligence level of the entire vehicle and enhance product quality. It has a novel structure and a compact layout. Two driving mechanisms are provided, each of which can drive the corresponding protective cover 3 to move and open and close the two openings 102 respectively. Such a setting is easy to control separately, and one of the openings 102 can be opened and closed as needed. When one charging socket 2 is used, the protective cover 3 corresponding to the other charging socket 2 can remain closed to prevent water from entering on rainy days, making it more convenient to use.
