Concealed door handles are typically integrated into the outer surface of the door, popping out only when needed to open the door. However, current concealed door handle technologies often only house a capacitive touchpad within the handle itself, allowing the handle to pop out with a light touch, but this results in inefficient use of the internal space.

[0003] In addition, some vehicles use digital key technology, which involves installing a digital key Bluetooth and controller on the vehicle body to enable keyless entry and start. However, the Bluetooth antenna is usually installed inside the vehicle body, which is easily affected by the vehicle's environment and has the defect of poor positioning accuracy.

[0049] Embodiments of the present invention are described in detail below, examples of which are illustrated in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0050] The Bluetooth antenna of this invention embodiment, such as Figure 1 As shown, it includes:

[0051] Antenna module 01 is electrically connected to Bluetooth controller 02 and is used to collect Bluetooth field strength value and send the Bluetooth field strength value to Bluetooth controller 02. The Bluetooth field strength value (RSSI value) is obtained through the antenna ANT in antenna module 01 and transmitted to Bluetooth controller 02 through high-speed automotive controller local area network (CAN with Flexible Data-Rate, CANFD).

[0052] Bluetooth controller 02 is electrically connected to antenna module 01, touch detection module 03 and integration module 04 respectively. It receives the Bluetooth field strength value sent by antenna module 01 and the touch signal sent by touch detection module 03, and sends the Bluetooth field strength value and the touch signal to integration module 04. The touch signal is used to characterize the touch state of capacitive touchpad.

[0053] In some embodiments, the Bluetooth controller 02 establishes communication with the antenna module 01 via CANFD, with the touch detection module 03 via a Universal Asynchronous Receiver / Transmitter (UART), and with the integrated module 04 via a General-Purpose I / O port (GPIO) or a Serial Peripheral Interface (SPI). The communication protocols used to establish communication are merely illustrative examples, and the specific communication protocols are not limited in this application embodiment.

[0054] The system receives the Bluetooth field strength value sent by the antenna module 01 via CANFD and the touch signal sent by the touch detection module 03 via UART, and sends the Bluetooth field strength value and touch signal to the integrated module via GPIO / SPI.

[0055] The touch detection module 03 is electrically connected to the Bluetooth controller 02 and sends the touch signal to the Bluetooth controller 02. The touch detection module 03 can be implemented as a touch detection chip (Capacitive Touch Panel (CTP)) or the like, and is not specifically limited.

[0056] The integrated module 04 is electrically connected to the Bluetooth controller 02, receives the Bluetooth field strength value and the touch signal sent by the Bluetooth controller 02, and sends the Bluetooth field strength value and the touch signal to the door controller 05.

[0057] Compared with related technologies, the embodiments of this application add a touch detection module 03 to the Bluetooth antenna. The integrated module 04 receives the Bluetooth field strength value sent by the antenna module 01 and the touch signal sent by the touch detection module 03 from the Bluetooth controller, and sends the touch signal to the door controller 05 for control, thereby enhancing the positioning accuracy of the Bluetooth antenna.

[0058] Please continue reading. Figure 1 The integrated module 04 is also electrically connected to the touch detection module 03, and is used to provide power to the Bluetooth controller 02 and the touch detection module 03 respectively.

[0059] The following is combined Figures 2-6 A door handle according to an embodiment of the present invention is described.

[0060] The door handle of this embodiment of the invention is used for rotating installation on the outside of a vehicle door. The door handle includes a handle and a functional module 1, which includes, for example, the following: Figure 1The Bluetooth antenna shown has a first mounting cavity in the handle. Functional module 1 is installed in the first mounting cavity and includes a main control board 11 and a Bluetooth antenna 12 arranged on the main control board 11, with the Bluetooth antenna 12 located on the side of the main control board 11 facing away from the door.

[0061] According to an embodiment of the present invention, a main control board 11 and a Bluetooth antenna 12 are installed in a first mounting cavity formed by the handle. The Bluetooth antenna 12 is arranged on the side of the main control board 11 facing away from the door. In this case, the signal emitted by the Bluetooth antenna 12 is only blocked by the handle, resulting in less interference. Furthermore, the position of the handle makes the Bluetooth antenna 12 higher, reducing the signal reflection from the ground and allowing the signal strength to attenuate linearly with the transmission distance, thereby improving Bluetooth positioning accuracy. Moreover, installing the main control board 11 and the Bluetooth antenna 12 in the first mounting cavity of the handle effectively utilizes the space of the first mounting cavity, resulting in higher space utilization.

[0062] It should be noted that the main control board 11 includes a circuit board and an RF controller arranged on the circuit board. The RF controller communicates with the Bluetooth antenna 12 through the circuit board. Taking a hidden door handle with a capacitive touchpad as an example, when the car owner carrying a terminal containing a Bluetooth module (remote key, mobile phone, or other terminal device) touches the handle, the terminal receives the signal emitted by the Bluetooth antenna 12 and simultaneously transmits an unlock signal. The vehicle receives the unlock signal emitted by the terminal and sends information to the vehicle lock module, realizing keyless unlocking. Among them, the Bluetooth high-precision positioning function of the digital key ensures that only the legitimate car owner can open the door, effectively improving vehicle security.

[0063] In some embodiments, such as Figures 2-4 As shown, the door handle also includes a sealing element 2 that covers the functional module 1, and the sealing element 2 is fixedly installed in the first mounting cavity.

[0064] The sealing element 2 covers the functional module 1 to separate the functional module 1 from the outside world, so that the functional module 1 will not be affected when the first mounting cavity is in a high temperature and high humidity or low temperature environment, making the functionality of the functional module 1 more reliable and its service life longer.

[0065] Specifically, the main control board 11 of the functional module 1 is electrically connected to the vehicle body main control module through the wiring harness 4. The sealing element 2 covers the functional module 1 and also covers the part of the wiring harness 4 that is electrically connected to the main control board 11, thereby effectively preventing moisture from contacting the functional module 1 through the gap between the sealing element 2 and the wiring harness 4 and affecting the function of the functional module 1.

[0066] In some embodiments, such as Figures 2-4As shown, the sealing element 2 includes a first housing 21 and a potting element 22. The first housing 21 has a second mounting cavity and an opening communicating with the second mounting cavity. The functional module 1 fits into the second mounting cavity through the opening. The potting element 22 seals the opening and fills the gap between the outer surface of the functional module 1 and the inner surface of the second mounting cavity through a potting process.

[0067] The potting component 22, formed by the potting process, seals the functional module 1. This sealing method is less expensive than other sealing methods, and the potting process does not damage electronic components on the functional module 1, such as the Bluetooth antenna 12. The functional module 1 remains functionally stable and reliable. Furthermore, the first housing 21, as a rigid component, works with the potting component 22 to seal the functional module 1, and also facilitates its secure connection to the handle, ensuring reliable installation of the functional module 1 within the handle's first mounting cavity.

[0068] Specifically, such as Figures 2-4 As shown, the lower end of the first housing 21 has an opening. The functional module 1 fits into the second mounting cavity through the lower opening. The potting part 22, formed by the potting process, fills the gap between the outer surface of the functional module 1 and the surface of the first mounting cavity, while also sealing the opening and making its outer surface smoothly connected to the outer surface of the first housing 21.

[0069] In some embodiments, the seal 2 includes a first injection molded part that covers the functional module 1 by a cold injection molding process. That is, the seal 2 is formed in a single injection molding process and completes the covering of the functional module 1, which can also achieve a reliable seal for the functional module 1.

[0070] In addition, when the first injection molded part is formed using a cold injection molding process, the highest temperature of the first injection molded part will not damage the electronic components in the functional module 1, and the functionality of the functional module 1 is stable and reliable.

[0071] Alternatively, the sealing element 2 includes a second housing and a second injection molded part. The second injection molded part is connected to the second housing through a secondary injection molding process, and the second injection molded part and the second housing together cover the functional module 1. In this case, the size of the second housing can be compared with the first housing 21 described above, and the size of the second injection molded part can be compared with the potting part 22 described above. Thus, the second injection molded part and the second housing can also achieve a reliable seal for the functional module 1.

[0072] Specifically, the second injection molded part is also formed by cold injection molding. The material of the second housing can be the same as or different from that of the second injection molded part, as long as it does not interfere with the signal sent by the functional module 1.

[0073] In some embodiments, such as Figure 5As shown, the outer surface of the car door is provided with a receiving groove, and the handle has a hidden position that is received in the receiving groove and a pop-out position that at least partially protrudes out of the receiving groove. Functional module 1 also includes a first capacitive touch panel 13, which is arranged on the side of the main control board 11 away from the car door. The first capacitive touch panel 13 and the Bluetooth antenna 12 are arranged at intervals along the length of the handle.

[0074] The door handle is a hidden door handle. The outer surface of the handle forms a sensing area corresponding to the first capacitive touch panel 13. When the owner touches the handle and is in the sensing area, the first capacitive touch panel 13 sends a pop-up signal to the main control board 11. The main control board 11 controls the vehicle power unit to work. The power unit drives the handle to rotate from the hidden position to the pop-up position, so that the door can be opened by gripping the handle.

[0075] The first capacitive touchpad 13 and Bluetooth antenna 12 are arranged at intervals along the length of the handle, ensuring that their functions do not interfere with each other. Furthermore, the first capacitive touchpad 13 and Bluetooth antenna 12 are both located on the main control board 11, resulting in higher integration of the functional module 1, better space utilization of the first mounting cavity, and lower overall cost of the door handle.

[0076] Specifically, taking the example of the first end of the handle being pivotally connected to the car door, the first capacitive touchpad 13 is closer to the second end of the handle than the Bluetooth antenna 12.

[0077] In some embodiments, such as Figure 6 As shown, the functional module 1 also includes a second capacitive touch panel 14, which is arranged on the side of the main control board 11 facing the door.

[0078] That is, the second capacitive touch panel 14 is located on the back of the main control board 11. At this time, when the handle is in the pop-up position and the driver's finger touches the back of the handle, the second capacitive touch panel 14 senses and sends a corresponding signal to the main control board 11. The main control board 11 controls the handle to remain in the pop-up position, thereby effectively preventing the handle from being accidentally rotated to the hidden position and pinching the finger.

[0079] In some embodiments, such as Figure 6 As shown, there are two second capacitive touch panels 14, which are arranged at intervals along the length of the handle.

[0080] At this time, the two second capacitive touchpads 14 correspond to the two positions on the back of the controller that will be touched by fingers, ensuring that no matter which position the fingers touch on the back of the controller, the controller will not be accidentally switched to the hidden position and pinch the fingers.

[0081] Specifically, such as Figure 6As shown, the two second capacitive touch panels 14 are generally distributed on all positions along the length of the back of the main control board 11, thereby ensuring that the second capacitive touch panel 14 can sense any touch when a finger touches any position on the back of the handle, thus making the door handle safer to use.

[0082] In some embodiments, such as Figure 2 and Figure 3 As shown, the door handle also includes an elastic element 3, which is sandwiched between the outer surface of the seal 2 and the inner surface of the first mounting cavity.

[0083] The seal 2 is fitted with a clearance within the first mounting cavity of the handle to prevent the two from squeezing against each other and causing damage to the functional module 1. At this time, the elastic element 3 undergoes elastic deformation through compression to be clamped between the outer surface of the seal 2 and the inner surface of the first mounting cavity, thereby achieving relative fixation of the position of the functional module 1 and the handle, effectively preventing the functional module 1 from shaking within the first mounting cavity and causing a difference in touch sensitivity between the first capacitive touch panel 13 and the second capacitive touch panel 14.

[0084] In some embodiments, the elastic element 3 includes a silicone gasket bonded to the outer surface of the seal 2.

[0085] By bonding the silicone gasket to the outer surface of the seal 2, it is ensured that the silicone gasket is not prone to misalignment when the seal 2 is fitted in the first mounting cavity, thus preventing it from affecting its reliable positioning of the seal 2. Simultaneously, the silicone gasket has stable material properties, a long service life, and high reliability in positioning the seal 2.

[0086] The vehicle according to embodiments of the present invention includes the features described above. Figures 2 to 6 The door handle shown in any of the pictures.

[0087] This invention also provides a door control method, which is applied to the vehicle described in the above embodiments, or a vehicle controller, such as... Figure 7 As shown, the method includes:

[0088] Step 701: Receive the Bluetooth field strength values ​​sent by each Bluetooth controller. Each vehicle door handle contains a Bluetooth antenna, which includes the Bluetooth controller and an antenna module. The Bluetooth controller is used to receive the Bluetooth field strength values ​​collected by the antenna module.

[0089] The Bluetooth antenna described in this application embodiment is built into the door handle of the car door. The antenna module collects the Bluetooth field strength value and sends the collected Bluetooth field strength value to the integrated module. The integrated module sends the received Bluetooth field strength value to the door controller. Each door controller sends the Bluetooth field strength value collected by the Bluetooth antenna to the vehicle controller (e.g., the vehicle motion domain control center XCU).

[0090] Step 702: Compare the Bluetooth field strength value with the reference Bluetooth field strength value to obtain a comparison result, and control the door to switch states based on the comparison result.

[0091] The reference Bluetooth field strength value is an empirical value that can be set according to business needs. For example, in this embodiment, the reference Bluetooth field strength value is a field strength range, set to: [-70dB, -40dB], [-65dB, -45dB]. Alternatively, the reference Bluetooth field strength value can also be set to a preset Bluetooth field strength value, such as -70dB, -50dB, etc. It should be noted that the reference Bluetooth field strength value is an illustrative example, and the specific reference Bluetooth field strength value is not limited. When the detected Bluetooth field strength value falls within the range of the reference Bluetooth field strength value, or when the Bluetooth field strength value is greater than or equal to the reference Bluetooth field strength value, the vehicle controller sends a control command to the body controller to switch the door to the open state. The body controller responds to the control command by opening the door.

[0092] If the detected Bluetooth signal strength value does not fall within the range of the reference Bluetooth signal strength value, or if the Bluetooth signal strength value is less than the reference Bluetooth signal strength value, continue to execute step 701.

[0093] Step 703: When it is determined that the car door is open, the touch state of the capacitive touchpad is determined to be active based on the capacitance change sent by the touch detection module; wherein, the touch detection module is used to detect the touch state of the capacitive touchpad by the capacitance change.

[0094] In some scenarios, after the control handle is held in the pop-up position and before it is returned to the hidden position, to prevent accidental pinching of the user's hand, the touch state of the capacitive touchpad is determined based on the capacitance change sent by the touch detection module. If active, touch control of the car door can be triggered.

[0095] In this embodiment of the application, when the car owner's finger touches the back of the handle, the second capacitive touch panel 14 senses and detects the change in capacitance, which indicates that the finger is still between the handle and the car door.

[0096] Step 704: If it is determined that the touch state of the capacitive touchpad is active, control the touch function of the door handle to be disabled.

[0097] To prevent accidental pinching, when a finger is detected between the handle and the door, the touch function of the door handle is disabled. That is, the touch function of the door handle is temporarily disabled until the finger is removed from the handle and the door.

[0098] After detecting that a finger has been withdrawn from the handle and the door, that is, when the capacitance change sent by the touch detection module is 0 (or the capacitance change is less than a preset error threshold), it indicates that no user's finger is located between the handle and the door, and the touch function of the door handle is restored.

[0099] The vehicle door control method provided in this application embodiment receives Bluetooth field strength values ​​sent by each Bluetooth controller. Each vehicle door handle includes a Bluetooth antenna, which comprises the Bluetooth controller and an antenna module. The Bluetooth controller receives the Bluetooth field strength value collected by the antenna module. The method compares the Bluetooth field strength value with a reference Bluetooth field strength value to obtain a comparison result, and controls the door to switch states based on the comparison result. When the door is determined to be open, the method determines whether the touch state of the capacitive touchpad is active based on the capacitance change sent by the touch detection module. The touch detection module detects the touch state of the capacitive touchpad through capacitance change. When the touch state of the capacitive touchpad is determined to be active, the method disables the touch function of the door handle. Compared with related technologies, as shown above, the hidden door handle in the vehicle improves the accuracy of Bluetooth positioning by integrating a Bluetooth antenna and a touch detection module. This is achieved by comparing the Bluetooth field strength value with a reference Bluetooth field strength value and controlling the door state to open based on the comparison result. Furthermore, by analyzing the capacitance change transmitted by the touch detection module, it determines whether the capacitive touchpad is active. If the capacitive touchpad is active, the touch function of the door handle is disabled, thus achieving an anti-pinch function for the user.

[0100] Please continue reading. Figure 5 The door handle includes a first capacitive touch panel and a second capacitive touch panel;

[0101] The door handle is a concealed door handle. The outer surface of the handle forms a sensing area corresponding to the first capacitive touch panel 13. When the owner's hand touches the handle and is located in the sensing area, the first capacitive touch panel 13 sends a pop-up signal to the main control board 11. The main control board 11 controls the vehicle power unit to work. The power unit drives the handle to rotate from the concealed position to the pop-up position, so that the owner can hold the handle to perform subsequent door opening operations. The second capacitive touch panel 14 is located on the back of the main control board 11. At this time, when the handle is in the pop-up position and the owner's finger touches the back of the handle, the second capacitive touch panel 14 senses and sends a corresponding signal to the main control board 11. The main control board 11 controls the handle to remain in the pop-up position.

[0102] To prevent fingers from being accidentally pinched, the touch state of the second capacitive touchpad is determined based on the capacitance change value sent by the touch detection module. If the touch state of the second capacitive touchpad is determined to be active, and the finger is located between the handle and the door, the touch function of the first capacitive touchpad in the door handle is disabled to achieve the anti-pinch function.
