[0038] Embodiments of the present invention are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0039] The following is for reference. Figures 1-6 This application describes a vehicle door assembly 100 according to an embodiment of the present invention. The door assembly 100 can be applied to a vehicle, but this application is not limited thereto. The door assembly 100 can be applied to other devices that require the installation of the door assembly 100. This application uses the application of the door assembly 100 to a vehicle as an example for illustration.

[0040] like Figure 2 , Figure 3 and Figure 6 As shown, the door assembly 100 according to an embodiment of the present invention includes: a door 10, a locking mechanism 70, a sensing unit 50, and a control unit 60. One end of the door 10 can be hinged to the vehicle body, achieving the effect of the door 10 being rotatably connected to the vehicle body. By opening or closing the door 10, the passenger compartment of the vehicle can be opened or closed. The locking mechanism 70 can be disposed at the other end of the door 10. The locking mechanism 70 is used to lock or unlock the door 10. When the locking mechanism 70 locks the door 10, the door 10 is fixedly connected to the vehicle body, making the door 10 unable to be opened, thereby achieving the effect of the door 10 closing the passenger compartment of the vehicle. When the locking mechanism 70 unlocks the door 10, the door 10 is disconnected from the vehicle body, allowing the door 10 to move relative to the vehicle body to open the door 10, thereby achieving the effect of the door 10 opening the passenger compartment of the vehicle. The sensing unit 50 can be installed at any location on the vehicle body or door 10 so that it can detect door opening signals. The control unit 60 is communicatively connected to the sensing unit 50 and the lock mechanism 70. The control unit 60 controls the lock mechanism 70 to unlock the door 10 based on the received door opening signal.

[0041] Specifically, when the sensing unit 50 detects a door opening signal, it transmits the signal to the control unit 60. The control unit 60 processes and analyzes the signal. After processing, it can control the lock mechanism 70 to unlock the door 10. When the lock mechanism 70 unlocks the door 10, the door 10 is disconnected from the vehicle body, allowing it to open and thus opening the passenger compartment. Furthermore, the door 10 can also be an automatically opening door. When the lock mechanism 70 unlocks the door 10, it automatically opens to a certain position relative to the vehicle body, eliminating the need for manual opening and improving the user experience and the vehicle's technological feel.

[0042] Therefore, by working together, the lock mechanism 70, the sensing unit 50 and the control unit 60 can achieve the effect of intelligently opening the vehicle door 10, which is beneficial to improving the user experience. At the same time, it can avoid setting a door handle on the vehicle door 10, thereby improving the flatness of the door 10 and reducing the air resistance of the vehicle during driving.

[0043] According to some embodiments of the present invention, such as Figure 2 and Figure 3 As shown, the sensing unit 50 may include a first sensing element 51 and a second sensing element 52. The outer panel of the door 10 may have a switch portion 11. The second sensing element 52 corresponds to the switch portion 11. The first sensing element 51 is adapted to sense the vehicle's door key to generate a first door opening signal. The second sensing element 52 is used to detect that the switch portion 11 is touched to generate a second door opening signal. The first door opening signal and the second door opening signal constitute a door opening signal. Further, the first sensing element 51 may be a key sensor. The first sensing element 51 may be located at any position on the vehicle body, such as the B-pillar or the front bumper. When there is a certain distance between the door key and the first sensing element 51, the first sensing element 51 can sense and identify the door key and generate the first door opening signal, and the first sensing element 51 transmits the first door opening signal to the control unit 60. Furthermore, when the user touches the switch 11, the second sensor 52 generates a second door opening signal and transmits the second door opening signal to the control unit 60. When the control unit 60 receives the first door opening signal and the second door opening signal at the same time, it transmits the door opening signal to the lock mechanism 70. After receiving the door opening signal, the lock mechanism 70 unlocks the door 10, thereby achieving the effect of opening the passenger compartment of the vehicle through the door 10.

[0044] According to some embodiments of the present invention, the first sensor 51 may include NFC (Near Field Communication) and / or Bluetooth (short-range wireless communication technology) and / or UWB (Ultra Wide Band). Further, the first sensor 51 may include NFC, Bluetooth, and UWB, and may also include one or two of NFC, Bluetooth, and UWB. Preferably, the first sensor 51 includes NFC, Bluetooth, and UWB. Further, the first sensor 51 may be disposed on the B-pillar of the vehicle, and the door key may be a user's mobile phone or card key, etc. When the user places the door key near the B-pillar of the vehicle, the first sensor 51 identifies the door key via NFC and / or Bluetooth and / or UWB, thereby achieving the effect of the door key triggering the first sensor 51 to generate a first door opening signal.

[0045] Furthermore, there can be multiple first sensors 51. These multiple first sensors 51 can be appropriately and spaced out at any location on the vehicle according to a preset unlocking range. This helps to increase the sensing and recognition range of the first sensors 51 for the vehicle door key, and also helps to improve the speed at which the first sensors 51 sense and recognize the vehicle door key, thereby improving the user experience.

[0046] According to some embodiments of the present invention, such as Figure 1 As shown, the second sensing element 52 includes a pressure sensor disposed on the switch portion 11; and / or a photosensitive sensor, wherein the switch portion 11 forms a light-transmitting area 111, and the photosensitive sensor corresponds to the switch portion 11. Further, the second sensing element 52 may include a pressure sensor and / or a photosensitive sensor. This can be understood as the second sensing element 52 including both a pressure sensor and a photosensitive sensor, or the second sensing element 52 including one of a pressure sensor and a photosensitive sensor. Preferably, the second sensing element 52 includes both a pressure sensor and a photosensitive sensor. Further, the pressure sensor may be disposed inside the door 10 and correspondingly disposed to the switch portion 11. When the user touches the switch portion 11, the pressure sensor can detect the pressure generated when touching the switch portion 11, and the pressure sensor generates a second door opening signal and transmits the second door opening signal to the control unit 60, thereby achieving the effect of the second sensing element 52 transmitting a second door opening signal to the control unit 60.

[0047] Furthermore, the light-transmitting area 111 has a light-transmitting effect, allowing light from the outer side of the door panel to pass through it, thus enabling light to pass through the door panel and illuminate the interior of the door 10. A photosensitive sensor can be located inside the door 10, and is adapted to correspond with the light-transmitting area 111, allowing light to pass through the light-transmitting area 111 and illuminate the photosensitive sensor, thereby enabling the photosensitive sensor to detect the intensity of light. Furthermore, when a user touches the switch 11, the user blocks the light-transmitting area 111, preventing light from passing through and illuminating the photosensitive sensor. When the photosensitive sensor detects weak or no light, it generates a second door-opening signal and transmits it to the control unit 60, thus enabling the second sensor 52 to transmit a second door-opening signal to the control unit 60.

[0048] Furthermore, when the second sensing element 52 includes a pressure sensor and a photosensitive sensor, the control unit 60 can only transmit an opening signal to the lock mechanism 70 after receiving the second opening signal transmitted by the pressure sensor and the photosensitive sensor, and also receiving the first opening signal transmitted by the first sensing element 51. This allows the control unit 60 to control the lock mechanism 70 to open. Therefore, by setting up second sensing elements 52 with various detection methods, the accuracy of the control unit 60 in identifying whether to transmit an opening signal to the lock mechanism 70 is improved. This helps avoid the risk of the control unit 60 erroneously controlling the lock mechanism 70 to open, thereby ensuring the operational stability of the vehicle door assembly 100.

[0049] Furthermore, there can be multiple second sensors 52. Multiple second sensors 52 can be appropriately and spaced on the switch part 11 according to the preset unlocking range, which helps to increase the detection and recognition range of the second sensors 52, and also helps to improve the detection and recognition speed of the second sensors 52, thereby improving the user experience.

[0050] According to some embodiments of the present invention, such as Figures 1-3As shown, the door assembly 100 may further include: a backlight 20, a switch portion 11 having a light-transmitting area 111, the backlight 20 being disposed inside the door 10 and corresponding to the light-transmitting area 111, and the backlight 20 being communicatively connected to the control unit 60. When the first sensor 51 senses the door key, the control unit 60 controls the backlight 20 to illuminate. Furthermore, the backlight 20 can be fixedly mounted inside the door 10 by adhesive or clips. When the backlight 20 is illuminated, the light emitted by the backlight 20 can pass through the light-transmitting area 111, achieving the effect of displaying the switch portion 11 on the outer panel of the door (i.e., the display state). When the user observes from the side of the outer panel of the door, the user can see that the switch portion 11 is illuminated, thus facilitating the user's observation of the switch portion 11, reducing the probability of accidental touch, and improving the user experience. Furthermore, when the backlight 20 is turned off, no light passes through the light-transmitting area 111, thus achieving the effect of hiding the switch part 11 in the outer panel of the door (i.e., the hidden state).

[0051] According to some embodiments of the present invention, when the distance between the first sensor 51 and the car door key reaches a first preset distance, the control unit 60 controls the backlight 20 to flash. As the distance between the first sensor 51 and the car door key gradually decreases, the flashing frequency of the backlight 20 gradually increases. When the distance between the first sensor 51 and the car door key reaches a second preset distance, the control unit 60 controls the backlight 20 to remain constantly lit. The first preset distance is greater than the second preset distance. Further, the first preset distance is A, where 1m ≤ A ≤ 3m, and the second preset distance is B, where 0m ≤ B ≤ 1.5m. Preferably, A = 2m and B = 0.5m. Further, when the backlight 20 flashes or remains constantly lit, the light emitted by the backlight 20 can pass through the light-transmitting area 111, achieving the effect of displaying the switch part 11 on the outer panel of the car door in a flashing or constantly lit manner, thereby improving the vehicle's intelligence. Therefore, by setting a first preset distance and a second preset distance, when the car door key is in different positions relative to the first sensor 51, the control unit 60 can change the flashing frequency of the backlight 20 according to the different relative distances between the car door key and the first sensor 51, so as to achieve the effect of the switch section 11 flashing or remaining constantly lit on the outer panel of the car door. It should be noted that when the distance between the first sensor 51 and the car door key is greater than the first preset distance, the backlight 20 is turned off.

[0052] According to some embodiments of the present invention, such as Figure 1As shown, the vehicle door assembly 100 may further include a vibration unit 30, which is disposed on the inner surface of the outer door panel of the door 10. The vibration unit 30 is communicatively connected to the control unit 60, and the control unit 60 controls the vibration unit 30 to vibrate according to the received door opening signal. Further, the vibration unit 30 can be a vibrator, and the control unit 60 can control the vibration unit 30 to vibrate according to the received door opening signal. The vibration unit 30 may be configured corresponding to the switch unit 11. When the user touches the switch unit 11, the vibration unit 30 vibrates, providing feedback to the user through the vibration generated by the vibration unit 30, thereby enabling the user to perceive the effect of touching the switch unit 11 and improving the user experience.

[0053] According to some embodiments of the present invention, such as Figure 4 As shown, the vehicle door assembly 100 may further include a heating unit 40. The outer panel of the door 10 has a switch portion 11. The heating unit 40 is disposed on the inner surface of the outer panel and corresponds to the switch portion 11. The heating unit 40 is communicatively connected to the control unit 60. The sensing unit 50 is also used to detect whether the outer surface of the switch portion 11 is covered by ice and snow. When the outer surface of the switch portion 11 is covered by ice and snow, the control unit 60 controls the heating unit 40 to operate. Further, the heating unit 40 can be a ring-shaped structure, so that the heating unit 40 can be arranged around the switch portion 11. When the heating unit 40 is heating, it can uniformly heat the switch portion 11, so that the switch portion 11 has a high temperature, thereby achieving the effect of melting ice and snow. Furthermore, when the sensing unit 50 detects that the outer surface of the switch part 11 is covered by ice and snow, the sensing unit 50 transmits a sensing signal to the control unit 60. The control unit 60 can control the heating unit 40 to work according to the sensing signal. The heating unit 40 heats the switch part 11, causing the temperature of the switch part 11 to rise, thereby achieving the effect of melting the ice and snow covering the outer surface of the switch part 11.

[0054] According to some embodiments of the present invention, the sensing unit 50 includes a temperature sensor 53, which is used to detect the temperature of the switch part 11 and determine whether the outer surface of the switch part 11 is covered by ice and snow based on the temperature of the switch part 11. Further, when ice and snow cover the outer surface of the switch part 11, the temperature of the switch part 11 is low. The temperature of the switch part 11 is detected by the temperature sensor 53. When the temperature sensor 53 detects that the temperature of the switch part 11 reaches the temperature at which ice and snow cover the switch part 11, the control unit 60 receives the sensing signal transmitted by the temperature sensor 53. The control unit 60 can control the heating unit 40 to operate according to the sensing signal, thereby achieving the effect of melting the ice and snow covering the outer surface of the switch part 11.

[0055] According to some embodiments of the present invention, the vehicle door assembly 100 may further include: a camera device for acquiring image information of the outer surface of the switch portion 11, the camera device being communicatively connected to the control unit 60, and determining whether the outer surface of the switch portion 11 is covered by ice or snow based on the image information. Further, the camera device may be installed in the rearview mirror of the door 10, enabling it to acquire image information of the outer surface of the switch portion 11. This application uses the example of the camera device being installed in the rearview mirror of the door 10 for illustration, but this application is not limited thereto; the camera device can be installed at any position where it can acquire image information of the outer surface of the switch portion 11. Furthermore, when ice and snow cover the outer surface of the switch part 11, the camera device captures image information of the outer surface of the switch part 11 and transmits it to the control unit 60. The control unit 60 determines that the outer surface of the switch part 11 is covered by ice and snow based on the image information. At the same time, the control unit 60 can combine the sensing signal transmitted by the temperature sensor 53 to further determine whether the outer surface of the switch part 11 is covered by ice and snow, thereby improving the control accuracy of the control unit 60. When the outer surface of the switch part 11 is covered by ice and snow, the control unit 60 controls the heating unit 40 to work, thereby achieving the effect of melting the ice and snow covering the outer surface of the switch part 11.

[0056] According to some embodiments of the present invention, such as Figure 3 and Figure 5 As shown, the switch portion 11 has a light-transmitting hole 112 to form a light-transmitting area 111. Furthermore, there can be multiple light-transmitting holes 112, arranged around the switch portion 11, such as... Figure 4 and Figure 5 As shown, multiple light-transmitting holes 112 are arranged circumferentially around the switch portion 11 to form a ring-shaped light-transmitting area 111. However, this application is not limited to this; the multiple light-transmitting holes 112 can form different patterns on the switch portion 11, such as rectangular or triangular patterns. Furthermore, the switch portion 11 can be integrally formed with the outer door panel, so that the switch portion 11 and the outer door panel are made from a single piece of metal sheet. Laser engraving is used to engrave multiple light-transmitting holes 112 on the switch portion 11, forming a light-transmitting area 111, thereby achieving the effect of arranging the light-transmitting area 111. Furthermore, the switch portion 11 can also be made of a light-transmitting material, and a special ceramic or coating can be applied to the outer surface of the door 10 to give the switch portion 11 a material texture, making the switch portion 11 appear the same as the outer door panel, thus improving the overall integrity of the door 10.

[0057] According to some embodiments of the present invention, such as Figure 1As shown, a light-transmitting structure is provided inside the light-transmitting hole 112. The light-transmitting structure can be a light-transmitting structural adhesive. The light-transmitting structural adhesive has good light transmittance. The light-transmitting structural adhesive can be injected into the light-transmitting hole 112 by filling. While meeting the requirement that light can pass through the light-transmitting hole 112, the light-transmitting structural adhesive can also achieve the effect of sealing the light-transmitting hole 112, thereby achieving the waterproof effect of the light-transmitting area 111 and thus avoiding the risk of rainwater seeping into the car door 10 through the light-transmitting hole 112.

[0058] According to the present invention, the vehicle includes the door assembly 100 of the vehicle of the above embodiment, which realizes the effect of intelligently opening the vehicle door 10, which is beneficial to improving the user experience. At the same time, it can avoid setting a door handle on the vehicle door 10, thereby improving the flatness of the door 10 and thus reducing the air resistance of the vehicle during driving.
