[0002] A car sliding door, also known as a sliding track door or sliding side door, is a type of door opening method in which the door slides horizontally along a track on the side of the car body to open and close. This design is not uncommon in the automotive field, especially in large MPVs (multi-purpose passenger vehicles) and some commercial vehicles. The sliding door design not only provides a convenient way to get in and out, especially in narrow spaces, but also increases the practicality and convenience of the vehicle.

[0003] Automobile sliding doors are usually equipped with electrical control devices. When the driver or passenger needs to open or close the door, they operate the control switch on the center console or the electrical control button on the sliding door. The electrical control device will receive the instruction and start the corresponding action.

[0004] With the advancement and development of science and technology, people expect car sliding doors to be both practical and technological and futuristic. To achieve this goal, a capacitive proximity sensing car sliding door controller is provided. Utility Model Content

[0008] By adopting the above technical solution: when an object (such as a human hand or other part of the body) approaches the sensor, the electric field distribution around the sensor will change, thereby causing a change in the sensor capacitance value. The MCU can sensitively capture this change and convert it into an electrical signal. Subsequently, these electrical signals are processed and ultimately trigger the automatic start and stop function of the sliding door. At the same time, the setting of the signal indicator enables the user to intuitively understand the working status of the sensing device.

[0009] Preferably, the sensor is a copper foil sensor, including a first copper foil sensor and a second copper foil sensor.

[0010] By adopting the above technical solution: the copper foil sensor can effectively sense the approach of external objects (such as human hands or other parts of the body), thereby realizing the automatic start and stop function of the car sliding door. In addition, the copper foil sensor has a long service life and economic practicality, which can ensure the stable operation of the system and relatively cheap production cost.

[0011] Preferably, the first copper foil sensor and the second copper foil sensor are in the shape of long strips, and are arranged parallel to each other at the same height.

[0012] By adopting the above technical solution: this setting can expand the sensing range and improve the accuracy and reliability of sensing.

[0013] Preferably, the signal indicator is an LED indicator light, including a first LED indicator light and a second LED indicator light.

[0015] Preferably, the LED indicator light includes four working states: off, breathing, flashing, and highlighted.

[0016] By adopting the above technical solution: the four working states of the LED indicator light, namely off, breathing, flashing, and highlighted, can respectively represent different system states. The user can quickly understand the current situation of the system by observing the state of the LED indicator light.

[0017] Preferably, transparent glue is filled between the housing and the PCB board.

[0018] By adopting the above technical solution: transparent glue can transmit light, making it easy for the LED light to be observed by the human eye, and the filling of transparent glue can fix and protect the PCB board to prevent it from being affected and damaged by the external environment, such as being eroded by water, etc. At the same time, transparent glue can also enhance the insulation performance of the capacitive proximity sensing automotive sliding door controller and increase the sensing distance, thereby improving its safety and accuracy.

[0019] Preferably, the front end of the shell is a translucent shell.

[0020] By adopting the above technical solution: the translucent shell design allows the light of the LED indicator to pass through, so that the user can clearly see the status of the LED indicator. At the same time, this design also increases the aesthetics and modernity of the product.

[0021] Preferably, the PCB board is provided with an inserting plate for fixing and installing the PCB board, and the housing is provided with a slot adapted to the inserting plate.

[0022] By adopting the above technical solution: the design of the plug-in board and the slot, the PCB board can be easily fixed and installed. This structure not only simplifies the installation process, but also improves the stability and reliability of the installation.

[0023] In summary, the present application includes at least one of the following beneficial technical effects:

[0024] 1. This application uses a copper foil sensor to sensitively sense the approach of external objects and realize the intelligent start and stop function of the sliding door. At the same time, the precise coordination of the sensor and the microcontroller unit ensures the accuracy and reliability of the sensing and improves the user experience;

[0025] 2. This application uses the LED indicator as a signal indicator, so that the user can intuitively understand the working status of the sensing device. The four different working states of the LED indicator represent different system states, so that the user can quickly understand the current situation of the system and make operational judgments conveniently;

[0026] 3. This application fills transparent glue between the housing and the PCB board, which not only fixes and protects the PCB board to prevent it from being affected and damaged by the external environment, but also enhances the insulation performance of the device and improves safety. At the same time, this design also increases the sensing distance and further improves the accuracy of the device. BRIEF DESCRIPTION OF THE DRAWINGS

[0031] The following is combined with Figure 1-3This application is described in further detail. Example

[0032] The present application embodiment discloses a capacitive proximity sensing automobile sliding door controller, referring to Figure 1 , Figure 2 and Figure 3 The capacitive proximity sensing automobile sliding door controller is installed in the door handle of the automobile sliding door, and is composed of a housing 1 and a PCB board 2 installed in the housing 1. A transparent potting glue 4 is filled inside the housing 1 and between the PCB board 2 to seal the PCB board 2 inside the housing 1.

[0033] A microcontrol unit 5 and a sensor are installed on the front of the PCB board 2. In this embodiment, the sensor is a copper foil sensor 22, which includes a first copper foil sensor 221 and a second copper foil sensor 222 in a long strip shape and arranged parallel to each other at the same height position at the bottom of the front of the PCB board 2. Two capacitors 21 with fixed values ​​are installed on the top of the back of the PCB board 2 to cooperate with the microcontrol unit 5 and the sensor for proximity sensing.

[0034] In order to more intuitively observe the working state of the capacitive proximity sensing automobile sliding door controller and facilitate users to understand whether the system is operating normally, a signal indicator is installed above the first copper foil sensor 221 and the second copper foil sensor 222. In this embodiment, it is an LED indicator 3, which includes four working states: off, breathing, flashing, and highlight. The LED indicator 3 is connected to the sensor through the internal circuit of the PCB board 2, and the light state is changed according to the change of the electrical signal from the sensor to the micro control unit 5. Each light state corresponds to a working condition.

[0035] In order to facilitate observation of the changing state of the light, the front end of the housing 1 is set to be translucent, and the light of the LED indicator light 3 can easily pass through, so that the user can clearly see the state of the LED indicator light 3 for operation.

[0036] When installing the PCB board 2 in the early stage, in order to make the PCB easy to fix, an insertion plate 23 is installed on the left side of the PCB board 2, and a slot 11 compatible with it is opened in the shell 1. The design of the insertion plate 23 and the slot 11 can easily realize the fixing and installation of the PCB board 2. This structure not only simplifies the installation process, but also improves the stability and reliability of the installation.

[0037] The working process and implementation principle of the embodiment are as follows:

[0038] The side of the PCB board 2 on which the sensor is installed faces the front end of the housing 1. The plug plate 23 on the PCB board 2 is aligned with the slot 11 opened in the housing 1 and pressed to fix it. Then, the interior of the housing 1 is filled with transparent glue 4 to enclose the PCB board 2 in the housing 1. Thanks to the translucent front end of the housing 1 and the setting of the transparent glue 4, the light of the LED indicator 3 installed on the PCB board 2 can easily pass through, allowing the user to clearly observe the status of the LED indicator 3 for subsequent operations.

[0039] When the sliding door is in a closed state and the sensor does not detect any approaching object, the first LED indicator light 31 is illuminated in a breathing manner to indicate the position of the user's hand;

[0040] When the sliding door is in a closed state, when the sensor detects the user's hand, the first LED indicator light 31 is highlighted and the second LED indicator light 32 is flashing, to indicate the sliding direction of the user's hand and the door opening direction. At this time, the user can unlock the door by sliding his hand from the first copper foil sensor 221 to the second copper foil sensor 222.

[0041] When the sliding door is in the sliding process, if the sensor does not detect any approaching object, the first LED indicator 31 and the second LED indicator 32 are both flashing to indicate normal operation. If there is no human intervention, the door will be opened or closed according to the established procedure.

[0042] When the sliding door is in the sliding process, when the sensor detects the user's hand, the first LED indicator 31 and the second LED indicator 32 are both in a high light state to indicate a warning and an emergency stop of the door opening and closing action;

[0043] When the sliding door is braked and in a stopped state during the sliding process, when the sensor detects the user's hand, the first LED indicator 31 is highlighted and the second LED indicator 32 is off, or the first LED indicator 31 is off and the second LED indicator 32 is highlighted, mainly depending on the specific position of the sliding door, to indicate the sliding direction of the user's hand and the door opening direction.

[0044] When the sliding door is in the open state, when the sensor does not detect any approaching object, the second LED indicator 32 is in a breathing state to indicate the position of the user's hand;

[0045] When the sliding door is in the open state, when the sensor detects the user's hand, the first LED indicator light 31 flashes and the second LED indicator light 32 is highlighted to indicate the sliding direction of the user's hand and the door closing direction. At this time, the user can close the door by sliding his hand from the second copper foil sensor 222 to the first copper foil sensor 221.

[0046] The above are preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
