The position response module cooperates with the non-contact sensor to detect the moving direction of the second housing and the relative position between the second housing and the first housing. The position response module transmits the detection result to a vehicle controller through the signal transmission interface. The indicator light module receives the vehicle signal sent by the vehicle controller through the signal transmission interface and controls the indicator light to work in the light-emitting state corresponding to the charging state in the vehicle signal.

[0008] In some schemes, the charging door integrated with an indication component, during the process that the second housing approaches the first housing, if the position response module detects that the position of the non-contact sensor reaches a set position, it is determined that the first housing and the second housing are in a closed state.

[0010] The charging door integrated with the indicating component in some schemes, the position response module detects the distance between the non-contact sensor and the position response module according to a set period and records;

[0011] If the distance is in a decreasing trend, it is determined that the second shell is close to the first shell, and if the distance is in an increasing trend, it is determined that the second shell is away from the first shell.

[0012] The charging door integrated with the indicating component in some schemes, in the indicating lamp module, when the indicating lamp is a single-color LED, the indicating lamp module controls the single-color LED to be in a constant, breathing or flickering light state according to the charging state adjustment signal frequency and duty cycle in the vehicle signal sent by the vehicle controller.

[0014] The charging door integrated with the indicating component in some schemes, in the indicating lamp module, when the indicating lamp is a multi-color LED, the indicating lamp module controls the multi-color LED to be in a constant, breathing or flickering light state with a specific color according to the charging state adjustment signal frequency, duty cycle and light color in the vehicle signal sent by the vehicle controller.

[0015] The charging door integrated with the indicating component in some schemes, the position response module sends the detection result to the indicating lamp module, and the indicating lamp module controls the indicating lamp to work in a light state corresponding to the detection result.

[0016] The charging door integrated with the indicating component in some schemes, the non-contact sensor and the control module mainboard are located at positions opposite to the pivot position.

[0017] In a second aspect, the technical scheme of the present application provides a vehicle, which comprises the charging door integrated with the indicating component according to any one of the first aspect.

[0018] Compared with the prior art, the above technical scheme provided by the present application has the following technical effects:

[0019] This application provides a charging door and vehicle with integrated indicator components. The charging door includes a first housing and a second housing, which are pivotally connected. The first housing is mounted on a charging door base, and the second housing moves closer to or further away from the first housing to close or open the charging door. A first opening / closing component and a second opening / closing component cooperate to lock or unlock the second housing and the first housing. A non-contact sensor is installed on the inner wall of the second housing, and a control module motherboard is installed inside the first housing. The control module motherboard integrates a position response module, an indicator light module, and a signal transmission interface. The position response module works with the non-contact sensor to detect the movement direction of the second housing and its relative position to the first housing, and transmits the detection result to the vehicle controller via the signal transmission interface. The indicator light module receives the vehicle signal sent by the vehicle controller via the signal transmission interface and controls the indicator light to operate according to the illumination state corresponding to the charging status signal. This application's solution uses a non-contact sensor and a position response module to detect the charging door's position status. The non-contact sensor is directly placed inside the second housing, and the position response module is integrated on the control module motherboard, requiring no additional space. In addition, the charging status can be indicated by indicator lights, and the indicator light module is also integrated on the control module motherboard, requiring no additional space. The charging door of this application integrates position detection and status indication within the charging door. The use of non-contact sensors reduces space occupation and improves compatibility and adaptability with other components. By placing both the position response module and the indicator light module on the control module motherboard, the entire charging door has the advantages of high integration, low power consumption, and strong coordination.

[0025] The specific embodiments of this application will be further described below with reference to the accompanying drawings.

[0026] It is readily understood that, based on the technical solution of this application, various structural and implementation methods can be interchanged by those skilled in the art without altering the essential spirit of this application. Therefore, the following detailed embodiments and accompanying drawings are merely illustrative examples of the technical solution of this application and should not be considered as the entirety of this application or as limitations or restrictions on the technical solution of the application.

[0027] This embodiment provides a charging door with an integrated indicator component, such as... Figure 1 As shown, it includes a first housing 1 and a second housing 3. The first housing 1 is used to mount on the charging door base 2 of the vehicle body (the first housing 1 and the charging door base 2 can be substantially flush or protrude in a specific shape), and its inner wall is provided with a first opening and closing member 11; the second housing 3 is pivotally connected to the first housing 1, and its inner wall is provided with a second opening and closing member 31 and a non-contact sensor 4; the second opening and closing member 31 cooperates with the first opening and closing member 11 to realize the opening or closing of the second housing 3 and the first housing 1, as shown in the figure, the pivotal connection can be realized by a pivot shaft 6. Figure 2 The diagram shows the control module motherboard 5, which is located inside the first housing 1. (Combined with...) Figure 2 and Figure 3 As shown, the control module motherboard 5 integrates a position response module, an indicator light module, and a signal transmission interface. The signal transmission interface includes a first interface 71, a second interface 72, a third interface 73, and a fourth interface 74. The position response module, in conjunction with the non-contact sensor 4, detects the movement direction of the second housing 3 and its relative position to the first housing 1. The position response module transmits the detection result to the vehicle controller via the signal transmission interface. For example, when the second housing 3 moves closer to the first housing 1, a signal indicating proximity between the second housing 3 and the first housing 1 is sent to the vehicle controller, indicating that the charging door is in the closing process. When the second housing 3 locks with the first housing 1, a signal indicating locking between the second housing 3 and the first housing 1 is sent to the vehicle controller, indicating that the charging door is closed. When the second housing 3 moves away from the first housing 1, a signal indicating separation between the second housing 3 and the first housing 1 is sent to the vehicle controller, indicating that the charging door is in the opening process. When the second housing 3 is fully open with the first housing 1, a signal indicating that the charging door is open is sent to the vehicle controller. The indicator light module receives vehicle signals sent by the vehicle controller via the signal transmission interface and controls the indicator lights to operate according to the lighting states corresponding to the charging states in the vehicle signals. The vehicle signals sent by the vehicle controller include the charging state, such as standby, charging gun inserted, charging in progress, and charging level. The indicator lights represent different charging states through different lighting states.

[0028] In the above scheme, the charging door includes a first shell 1 and a second shell 3, and the first shell 1 and the second shell 3 are pivotally connected. The first shell 1 is mounted on the charging door base 2, and the second shell 3 is close to or away from the first shell 1 to realize the closing or opening of the charging door, and the first opening and closing part 11 and the second opening and closing part 31 cooperate to close and open, realize the locking or unlocking of the second shell 3 and the first shell 1. A non-contact sensor 4 is arranged on the inner wall of the second shell 3, and a control module mainboard 5 is arranged inside the first shell, and the control module mainboard 5 is integrated with a position response module, an indicator light module and a signal transmission interface. The position response module cooperates with the non-contact sensor 4 to detect the moving direction of the second shell 3 and the relative position between the second shell 3 and the first shell 1, and transmits the detection result to the vehicle controller through the signal transmission interface. The indicator light module receives the vehicle signal sent by the vehicle controller through the signal transmission interface and controls the indicator light to work in the light-emitting state corresponding to the charging state signal. In the above scheme, the non-contact sensor and the position response module are used to realize the detection of the position state of the charging door. The non-contact sensor is directly arranged inside the second shell, and the position response module is integrated on the control module mainboard, so that no additional space is occupied. In addition, the charging state can be indicated by the indicator light, and the indicator light module is also integrated on the control module mainboard, without occupying additional space. The charging door of the present application integrates position detection and state indication in the charging door. The non-contact sensor can reduce the occupied space and improve the compatibility and adaptability with other components. The position response module and the indicator light module are arranged on the control module mainboard, and the entire charging door has the advantages of high integration, low energy consumption and strong cooperation.

[0029] In the above scheme, the non-contact sensor 4 can include a laser sensor, an ultrasonic sensor, a Hall sensor, and a radio frequency identification (RFID) sensor, etc. The laser sensor detects the position and distance of the second shell by means of a laser beam. The distance to the first shell 1 and the second shell 3 can be calculated by emitting and receiving laser pulses and measuring the time for the laser to return. The ultrasonic sensor detects the distance, position, and other information between the two shells by means of the propagation characteristics of ultrasonic waves in the air through the emission and reception of ultrasonic signals. The principle of the Hall sensor is that when a magnetic field acts on the Hall element, a Hall voltage is generated. By detecting the voltage, the change of the magnetic field can be sensed, and thus the position parameter of the object can be measured. Therefore, by arranging a magnetic field element on the first shell 1, a Hall element on the position response module, and a sensing element for voltage detection of the Hall element, when the distance between the second shell 3 and the first shell 1 changes, the distance between the magnetic field element and the Hall element changes, and the voltage generated by the Hall element changes. By pre-setting the mapping relationship between the voltage of the Hall element and the distance, the corresponding distance data can be found after detecting the voltage of the Hall element. The radio frequency identification (RFID) sensor is composed of a reader and an electronic tag. The reader communicates with the electronic tag through radio frequency signals to realize the identification and information reading of the object to which the tag is attached. Therefore, the reader and the electronic tag can be arranged in the first shell 1 and the second shell 3 respectively to realize distance measurement. The above description of the non-contact sensor 4 is only an example. In actual application, a measuring element with a matching function can be selected and arranged in the first shell 1 and the second shell 3 respectively to measure the distance.

[0030] In the above scheme, if the position response module detects that the position of the non-contact sensor 4 reaches a set position during the process of the second shell 3 approaching the first shell 1, it is determined that the first shell 1 and the second shell 3 are in a closed state. The set position can be selected according to an empirical value, i.e., after reaching this position, the first closure 11 and the second closure 31 have basically contacted, and only need to be further approached to realize the locking of the first closure 11 and the second closure 31. Correspondingly, if the position response module detects that the position of the non-contact sensor 4 reaches a set position during the process of the second shell 3 moving away from the first shell 1, it is determined that the first shell 1 and the second shell 3 are in an open state. As mentioned above, the set position can be selected according to an empirical value, i.e., after reaching this position, the first closure 11 and the second closure 31 are only in a contact state and have not been locked, and only need to be further moved away to realize the complete unlocking of the first closure 11 and the second closure 31, and the opening of the charging door.

[0031] Preferably, the position response module detects and records the distance between the non-contact sensor and the position response module at a set period; if the distance is in a decreasing trend, it is determined that the second shell 3 is approaching the first shell 1, and if the distance is in an increasing trend, it is determined that the second shell 3 is away from the first shell 1. Each time the distance collected can be marked in the coordinate system, and the distance trend can be intuitively displayed by recording the distance collected continuously in the coordinate system over time, so that the position change of the second shell 3 can be obtained simply and accurately.

[0032] In some preferred schemes, in the indicator light module, when the indicator light is a single-color LED, the indicator light module controls the single-color LED to be in a constant, breathing or flickering light state according to the charging state adjustment signal frequency and duty cycle in the vehicle signal sent by the vehicle controller, and in combination with Figure 4 As shown, the operation of adjusting the signal frequency and duty cycle can be realized by an LED driving chip. By controlling the single-color LED to be in a constant, breathing or flickering light state, the charging state can be represented, which can include handshake with the charging pile, charging in progress, charging completion, scheduled charging and charging failure, etc. Further, when the single-color LED is in a breathing or flickering light state, the breathing or flickering rate thereof is controlled. In this scheme, different light languages of the single-color LED light can represent a variety of states, but the size of the charging door does not need to be increased, and the miniaturization and integration requirements of vehicle design are still met. As another implementation manner, in the indicator light module, when the indicator light is a multi-color LED, the indicator light module controls the multi-color LED to be in a constant, breathing or flickering light state with a specific color light according to the charging state adjustment signal frequency, duty cycle and light color in the vehicle signal sent by the vehicle controller. That is, the multi-color LED light can represent more states than the single-color LED light. In specific implementation, the control circuit framework shown in Figure 4 can be used, in which the resistors, triodes / MOS tubes are realized by using existing electronic elements. In the figure, V BAT represents the power supply of the vehicle, VICM represents the vehicle interface control module, and BCM represents the body control module, i.e., VICM and BCM represent the vehicle controller. In combination with Figures 2 to 4As shown, the signal transmission interface can be connected with a vehicle controller in communication, the control module mainboard receives the vehicle signal sent by the vehicle controller, the vehicle signal includes the charging state signal, and the light emitting state of the indicator light is controlled by the indicator light module to prompt the charging state of the vehicle. Therefore, in the scheme of the embodiment, the signal transmission interface sends the opening and closing states of the first shell 1 and the second shell 1 to the vehicle controller. The vehicle controller can send the charging state to the control module mainboard, so that different charging states, vehicle states and the like are represented by different states of the LED.

[0033] Further preferably, as Figure 5 As shown, the position response module is further connected with the indicator light module. The position response module sends the detection result to the indicator light module, and the indicator light module controls the indicator light to work in the light emitting state corresponding to the detection result. When the second shell 3 is opened, the indicator light can prompt that the second shell 3 is in an open state, which can prompt the operator that the charging gun can be inserted to perform charging.

[0034] In specific connection, the first interface 71 can be connected with a power supply (that is, the entire control module mainboard is powered through the first interface 71), the second interface 72 is connected with a signal line (for example, the position response module feeds back the opening and closing state of the vehicle charging door through the second interface 72), the third interface 73 is connected with the ground, and the fourth interface 74 is connected with a vehicle LIN line (that is, the vehicle signal sent by the vehicle controller and the like can be received through the fourth interface 74). In specific implementation, the first opening and closing member 11, the second opening and closing member 31, the non-contact sensor 4 and the control module mainboard are located at positions opposite to the pivot positions, that is, at the distal end of the pivot shaft. In this way, the detection of the position response can be avoided during the opening and closing process of the charging door.

[0035] The embodiment of the application also provides a vehicle including the charging door with the integrated indicator component.

[0036] According to the needs, the above technical solutions can be combined to achieve the best technical effect.

[0037] The above is only the principle and preferred embodiment of the application. It should be noted that, for those skilled in the art, on the basis of the principle of the application, a number of other variants can also be made, which should be regarded as the protection scope of the application.
