In the following description, numerous specific details are provided to give a thorough understanding of embodiments of the present application. One skilled in the relevant art will recognize, however, that the

[0026] The present application will be further described with reference to the drawings and specific embodiments. It is to be understood that the embodiments described below are merely illustrative of the present application and that various modifications can be made by those skilled in the art, now or in the future, without departing from the basic concept of the application. Therefore, the scope of the application is not intended to be limited to the embodiments described below.

[0027] As shown in Figure 1 and Figure 2 The present embodiment provides an icing detection device for a charging port cover, comprising a charging port seat 1, a charging port cover 2, a driving mechanism 3, a displacement sensor 4 and a controller 5. The charging port seat 1 has a containing space 11 and an opening 12 communicating with the containing space 11. The charging port cover 2 is connected to the charging port seat 1 and has an open state and a closed state relative to the charging port seat 1. In the open state, the charging port cover 2 can open the opening 12, allowing the user to charge the vehicle. In the closed state, the charging port cover 2 covers the opening 12 and can move relative to the opening 12. The driving mechanism 3 is arranged on the charging port seat 1 and acts on the charging port cover 2, and is configured to drive the charging port cover 2 in the closed state to move along the direction of entry and exit of the opening 12. The displacement sensor 4 is arranged in the containing space 11 and is adapted to detect the displacement of the charging port cover 2 relative to the opening 12 in the closed state. The controller 5 is connected with the driving mechanism 3 and the displacement sensor 4. In this way, the user can start the driving mechanism 3 through the controller 5, use the driving mechanism 3 to act on the charging port cover 2 in the closed state, and detect whether the charging port cover 2 produces displacement under the action of the driving mechanism 3 through the displacement sensor 4, and then determine whether the charging port cover 2 is unable to move due to icing. Compared with the temperature detection method, the above-mentioned physical actuation method can effectively improve the accuracy of icing detection of the charging port cover 2 and reduce the probability of false icing.

[0028] For example, as shown in Figure 1 and Figure 2 In this embodiment, the charging port base 1, as a carrier of the charging terminal of the vehicle, has a receiving space 11 and an opening 12 communicating with the receiving space 11, one end of the charging port cover 2 can be hinged to one side of the opening 12 of the charging port base 1, and the hinge end is arranged in parallel with the plane of the opening 12, so that the charging port cover 2 can be flipped relative to the charging port base 1, thereby realizing the switching of the charging port cover 2 between the open state and the closed state relative to the charging port base 1; at the same time, the charging port cover 2 and the opening 12 are adapted in shape and size, for example, the outer contour of the charging port cover 2 is the same as the shape of the opening 12 and is adapted in size, so that the charging port cover 2 can cover the opening 12 in the closed state, and the other end of the charging port cover 2 can move inward to a certain extent along the in-out direction of the opening 12 in the closed state. The driving mechanism 3 is arranged on the charging port base 1 and can provide a force to the charging port cover 2, which can drive the charging port cover 2 in the closed state to move along the in-out direction of the opening 12, and the specific structure is not limited here; it can be understood that the force can act on the charging port cover through physical contact, for example, a motor connected to the hinge end of the charging port cover 2 is used as the driving mechanism 3, and the other end of the charging port cover 2 is driven to rotate around the hinge end by the driving force provided by the motor; the force can also act on the charging port cover through non-direct contact, for example, electromagnets arranged in the in-out direction of the opening 12 are used as the driving mechanism 3, and the other end of the charging port cover 2 in the closed state is attracted to move by the magnetic force provided by the electromagnets. The displacement sensor 4 can be an optical displacement sensor 4, which is arranged in the receiving space 11 corresponding to the other end of the charging port cover 2 to detect the displacement of the charging port cover 2 relative to the opening 12 in the closed state. The controller 5 can be a car ECU (Electronic Control Unit) or a lower controller connected to the ECU, which is connected with the driving mechanism 3 and the displacement sensor 4, can send start / stop signals to the driving mechanism 3 and the displacement sensor 4 according to the automatic detection or the instructions issued by the user manually, to control the start / stop of the driving mechanism 3 and the displacement sensor 4, and can receive and process the movement data of the charging port cover 2 detected by the displacement sensor 4, and then judge whether the charging port cover 2 is unable to move due to icing.

[0029] It can be understood that the above-mentioned triggering mode of ice detection can be automatically triggered based on the preset conditions in the controller 5, such as when there is a charging demand and the ambient temperature is lower than 0 degrees. It can also be manually triggered by the user based on the charging demand. The receiving window of the manual triggering instruction can be a physical button arranged on the vehicle body (such as the center console, steering wheel, or door, etc.) or a touch button on the display screen of the vehicle system. It can also be a virtual button of the corresponding program control instruction in the mobile terminal (such as a mobile phone or a tablet computer, etc.) connected with the vehicle system. It can also be a voice control module of the vehicle system for receiving voice control instructions. The above-mentioned various instruction issuing modes can control the start of the ice detection device, which can effectively improve the operation experience of the user.

[0030] In some embodiments, as shown in Figure 1 and Figure 2 , the driving mechanism 3 includes an electromagnetic component 31 capable of generating magnetism by being energized and a connecting piece 32 capable of being magnetically attracted, and the connecting piece 32 is arranged on the charging port cover 2. The electromagnetic component 31 is arranged in the accommodation space 11 corresponding to the connecting piece 32 and is arranged spaced apart from the connecting piece 32 in the approach direction of the opening 12. The electromagnetic component 31 is connected with the controller 5, and the energization or de-energization of the electromagnetic component 31 can be controlled through the controller 5. In this way, the electromagnetic component 31 can generate magnetic attraction to the connecting piece 32 when it is energized. The connecting piece 32 drives the charging port cover 2 to approach the electromagnetic component 31 based on the magnetic force, that is, the movement of the charging port cover 2 is realized. The electromagnetic component 31 and the connecting piece 32 are used as the driving mechanism 3, which not only has a simple structure, is easy to operate, and has a fast response speed, but also has a small overall structure size, occupies less space, and can also avoid physical impact or shear damage to the charging port cover 2 and the connecting end of the charging port cover 2 and the charging port seat 1 caused by a high-power driving mechanism 3.

[0031] In some embodiments, as shown in Figure 1 , the connecting piece 32 can be a metal sheet fixed to the charging port cover 2, such as an armature, which can be magnetically attracted. The electromagnetic component 31 is energized to have magnetism, so that the connecting piece 32 and the charging port cover 2 approach the electromagnetic component 31, and the movement of the charging port cover 2 is realized.

[0032] Of course, at least part of the area of the charging port cover 2 can also be configured as the connecting piece 32, and the charging port cover 2 or at least part of the area of the charging port cover 2 constituting the connecting piece 32 is made of a metal material capable of being magnetically attracted. In this way, the electromagnetic component 31 with magnetism can directly magnetically attract the charging port cover 2, so that the charging port cover 2 approaches the electromagnetic component 31 to realize the movement of the charging port cover 2.

[0033] In some embodiments, as shown in Figure 1As shown, the icing detection device further comprises a damping mechanism 6, which is installed on the charging port seat 1 and has an acting end located in the spaced region of the electromagnetic assembly 31 and the connecting piece 32 along the in-out direction of the opening 12, and is adapted to provide a damping force for the opposite movement of the charging port cover 2 and the charging port seat 1. In this way, when the electromagnetic assembly 31 attracts the connecting piece 32 to facilitate the movement of the charging port cover 2, the approaching speed of the connecting piece 32 and the charging port cover 2 can be slowed down, so as to reduce or avoid the collision and noise caused by the too fast approaching speed of the connecting piece 32 and the charging port cover 2.

[0034] For example, as shown in Figure 1 The damping mechanism 6 comprises a sleeve 61, a piston rod 62 and an elastic member 63. One end of the sleeve 61 is connected to the charging port seat 1, and the other end of the sleeve 61 is telescopically connected to one end of the piston rod 62 along the in-out direction of the opening 12. The other end of the piston rod 62 is located in the spaced region of the electromagnetic assembly 31 and the connecting piece 32 along the in-out direction of the opening 12. The elastic member 63 is arranged between the sleeve 61 and the piston rod 62 and can provide a force distributed along the in-out direction of the opening 12 to the sleeve 61 and the piston rod 62. In this embodiment, the elastic member 63 can be a compression spring, and the two ends of the compression spring abut against the sleeve 61 and the piston rod 62 respectively, so that the other end of the piston rod 62 extends out of the sleeve 61. In this way, when the connecting piece 32 and the charging port cover 2 approach the electromagnetic assembly 31, they can contact and abut against the other end of the piston rod 62 and make the piston rod 62 retract into the sleeve 61 against the force of the elastic member 63, so as to slow down the approaching speed of the connecting piece 32 and the charging port cover 2. Preferably, when the charging port cover 2 is in the closed state relative to the charging port seat 1, the other end of the piston rod 62 abuts against the connecting piece 32 or the charging port cover 2 in the normal state, so that the collision or impact between the connecting piece 32 or the charging port cover 2 and the piston rod 62 can be further avoided.

[0035] As shown in Figure 1 and Figure 2 In another embodiment, a thermal management system for a charging port cover is also provided, which comprises the icing detection device in the above embodiments and a heating device 7 connected to the controller 5 and controlled by the controller 5 to start or stop. When the displacement sensor 4 detects that the actual displacement of the charging port cover 2 is less than the preset displacement, it can be judged that the charging port cover 2 cannot be moved due to icing. In this case, the heating device 7 can be started to heat the charging port cover 2 to achieve ice removal. The heating method of the heating device 7 for the charging port cover 2 can be direct heating of the charging port cover 2 or indirect heating of the charging port cover 2 by heating the charging port seat 1 and conducting heat to the charging port cover 2 through the charging port seat 1.

[0036] In some embodiments, as shown in Figure 1 andFigure 2 As shown, the heating device 7 includes a first heating unit 71, which is an electric heating element disposed on the charging port cover 2 and / or the charging port base 1. For example, it is an electric heating wire or electric heating sheet covering the outer surface of the charging port cover 2 / charging port base 1 or encasing the substrate inside the charging port cover 2 / charging port base 1. The controller 5 controls the start / stop of the first heating unit 71 by turning the electric heating element on / off.

[0037] In some embodiments, such as Figures 1 to 3 As shown, the heating device 7 also includes a second heating unit 72, which includes a heating pipe 721 and a solenoid valve 722. The heating pipe 721 is attached to the surface of the charging port socket 1, and both ends of the heating pipe 721 are connected to the water outlet section of the cooling circuit used to cool the battery or electric drive in the vehicle. The solenoid valve 722 is located at the water inlet end of the heating pipe 721 and is connected to the controller 5. The controller 5 controls the opening and closing of the solenoid valve 722 by turning it on and off, thereby realizing the start / stop control of the second heating unit 72. In this way, during the operation of the vehicle, the waste heat of the battery cooling circuit or electric drive cooling circuit in the vehicle's thermal management architecture can be used to heat the charging port socket 1, and the charging port socket 1 can be used to conduct heat to the charging port cover 2, so that the charging port cover 2 can be heated to achieve de-icing.
