[0045] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0046] like Figures 1-8 As shown in the figure, this application embodiment provides a door assembly for a vehicle.

[0047] This door assembly includes a door 100 and a door handle 200. The door handle 200 is a concealed door handle. The door handle 200 is installed on the door 100, and when the door handle 200 is in a concealed state, the length direction of the door handle 200 is parallel to the height direction of the door 100.

[0048] It should be noted that when the door 100 is assembled onto the vehicle, the height direction of the door 100 is consistent with the extension direction from the top to the bottom of the door. The height direction of the door 100 can be consistent with the vertical direction or approximately consistent with the vertical direction. The parallelism between the length direction of the door handle 200 and the height direction of the door 100 means that the length direction of the door handle 200 is parallel to the height direction of the door 100, or approximately parallel to the height direction of the door 100. For example, the angle between the length direction of the door handle 200 and the height direction of the door 100 can be less than or equal to 15°.

[0049] In this embodiment, the door handle 200 is vertically mounted on the car door 100. When holding the door handle 200, the user only needs to slightly twist their wrist (the twisting angle of the wrist is smaller than when holding a horizontal door handle), or even does not need to twist their wrist at all. The wrist is in a natural vertical position, which is more in line with ergonomics and makes the door pulling action less strenuous (especially for heavy doors). This reduces hand fatigue during the door opening process and solves the problem in the prior art where the door handle of the vehicle is horizontally mounted, requiring the user to twist their wrist to exert force when opening the door, which easily increases hand fatigue.

[0050] To make the door handle 200 in this embodiment a concealed door handle, the vehicle door 100 is provided with a first mounting space, and the door handle 200 can be movably mounted in the first mounting space so that the door handle 200 can switch between an extended state and a concealed state. When the door handle 200 is in the extended state, at least a portion of the door handle 200 extends beyond the vehicle door 100, and the portion extending beyond the vehicle door 100 forms a gripping area 240 for the user to grasp; when the door handle 200 is in the concealed state, the door handle 200 is located within the first mounting space, that is, it does not protrude from the outer wall of the vehicle door 100.

[0051] In this case, when the door handle 200 is not in use, hiding the door handle 200 inside the door 100 helps to improve the vehicle's aesthetics and reduces wind resistance during driving, which is more in line with the current trend of vehicle technology and quality development.

[0052] There are several ways to movably install the door handle 200 in the first installation space. In one optional embodiment, the door handle 200 can be movably disposed in the first receiving space in the direction from inside the vehicle to outside the vehicle. The door handle 200 moves outward to extend beyond the door 100 to switch to the extended state, and the door handle 200 moves inward to retract into the first installation space to switch to the hidden state.

[0053] In another alternative embodiment, the door handle 200 may be rotatably mounted on the door 100.

[0054] Specifically, the first mounting space can be a mounting hole or slot on the door handle 200 facing outwards. The door handle 200 can be provided with a pivot. Along the axial direction of the pivot, the two opposite inner walls of the first mounting space can be provided with receiving grooves for engaging with the end of the pivot. The end of the pivot can extend into the receiving groove and rotatably engage with the receiving groove to realize the rotatable connection between the door handle 200 and the door 100.

[0055] Furthermore, at least one of the two opposing inner walls of the first installation space may be provided with a bearing 900. The outer ring of the bearing 900 may be fixedly connected to the inner wall of the receiving groove by means of interference fit or the like. The inner ring of the bearing 900 may be fixedly connected to the rotating shaft of the door handle 200 by means of interference fit or the like, so that the door handle 200 and the car door 100 can be rotatably connected by the rotating shaft and the bearing 900.

[0056] Along the length of the door handle 200, the door handle 200 includes a first end 210 and a second end 220. When the first end 210 is pressed, the second end 220 can extend beyond the vehicle door 100, thereby switching the door handle 200 to the extended state. In this case, the user can switch the door handle 200 to the extended state simply by pressing the first end 210, making the operation simple and convenient.

[0057] The door assembly may also include an elastic element that acts on the door handle 200 and the door 100 to drive the door handle 200 to switch to a hidden state. This structure uses the elastic element to enable the door handle 200 to automatically switch to a hidden state. The structure is simple and reliable and facilitates the switching of the state of the door handle 200.

[0058] Optionally, the elastic element can be a torsion spring, which includes a coil and two ends extending beyond the coil. The coil can be sleeved on the pivot of the door handle 200, and the two ends can respectively abut against the door handle 200 and the door 100. In the hidden state, the torsion spring is in its initial state. During the process of the door handle 200 switching from the hidden state to the extended state, the torsion spring accumulates elastic potential energy to restore its initial state. After the user releases the door handle 200, the torsion spring returns to its initial state under the action of the elastic potential energy and drives the door handle 200 to switch to the hidden state.

[0059] Of course, in other alternative embodiments, the elastic element can also be a helical spring, an elastic column, etc.

[0060] When extended, the angle between the door handle 200 and the first side wall 250 facing the interior of the vehicle and the height direction of the door 100 is α, where 30°≤α≤60°. This angle range facilitates the user's grip on the door handle 200, improving the user's comfort in holding the door handle 200 and the ease with which the user can pull the door handle 200 outward.

[0061] The door assembly may also include a door lock mechanism 300 and a first transmission component 410. The first transmission component 410 connects the door handle 200 and the door lock mechanism 300. When the door handle 200 is in the extended state, pulling the door handle 200 towards the outside of the vehicle will cause the door handle 200 to switch to the unlocked state through the first transmission component 410. In this case, the manual door opening function of the door 100 can be realized.

[0062] When the door needs to be opened manually, a force towards the inside of the vehicle can be applied to the first end 210 of the door handle 200. Figure 3 (The arrow in the text indicates the direction of force application) The first end 210 of the door handle 200 rotates around the axis inwards towards the inside of the vehicle, and the second end 220 tilts outwards towards the outside of the vehicle, forming an angle of 30°-60° with the door, exposing the gripping area 240 of the door handle 200. When the door handle 200 is manually pulled outwards, the door handle 200 drives the door lock mechanism 300 of the door to move through the first transmission component 410, thereby unlocking the door lock mechanism 300 and opening the door 100.

[0063] Optionally, the first transmission component 410 can be a first connecting rod. One end of the first connecting rod can be rotatably connected to the door handle 200 via a pin, and the other end can be rotatably connected to the lever (also called a lever lug) of the door lock mechanism 300 via a pin. Pulling the door handle 200 outward causes the door handle 200 to move, which in turn causes the lever to rotate, thus unlocking the door lock mechanism 300. It should be noted that the structure and unlocking / locking principle of the door lock mechanism 300 are existing technologies and will not be described in detail here.

[0064] Optionally, the first transmission component 410 can also be a pull cable. One end of the pull cable can be connected to the door handle 200, and the other end can be connected to the lever of the door lock mechanism 300. When the door handle 200 is pulled outward, the lever is rotated by the pull cable to unlock the door lock mechanism.

[0065] In this embodiment, the door assembly may further include a display device 500, a fingerprint recognition module, and a door handle controller 710.

[0066] The display device 500 can be an LCD screen, and the fingerprint recognition module can be integrated into the LCD screen, for example, it can be integrated under the LCD screen or integrated inside the LCD screen. A fingerprint collection area 540 is formed on the LCD screen. When the user places his finger on the fingerprint collection area 540, the fingerprint recognition module can collect and recognize the fingerprint.

[0067] The door handle 200 may be provided with a second mounting space 230, which may be a mounting hole or slot facing outwards. The display device 500 may be provided in the second mounting space 230 of the door handle 200. The display device 500 includes a locked state and an unlocked state. In the unlocked state, the display device 500 displays multiple function areas.

[0068] Both the display device 500 and the fingerprint recognition module can communicate with the door handle controller 710 via wiring harness 800, wireless connection, or Bluetooth connection. When the fingerprint recognition module recognizes the target fingerprint (referring to the fingerprint pre-registered by the user), the fingerprint recognition module transmits this signal to the door handle controller 710. The door handle controller 710 can control the display device 500 to switch to the unlocked state. When the display device 500 is in the unlocked state, when a certain function area of ​​the display device 500 is clicked, the display device 500 senses that the function area has been clicked and transmits this signal to the door handle controller 710. The door handle controller 710 detects that the function area has been triggered.

[0069] The door handle controller 710 can also communicate with the vehicle's central controller 720 via wiring harness 800, wireless connection, or Bluetooth connection. When any function area is triggered, the door handle controller 710 can transmit the signal of the triggered function area to the central controller 720. The central controller 720 controls the operation of the function mechanism corresponding to the function area to realize the corresponding function of the function area.

[0070] In this case, when the door assembly of the present application embodiment is used on a vehicle, the user can operate the vehicle's functional mechanisms from outside the vehicle via the display device 500 on the door handle 200, such as starting the vehicle, raising or lowering the windows, etc. In this way, the operation of the functional mechanisms can be operated without entering the vehicle, simplifying the vehicle use process and better conforming to the current development trend of vehicle intelligence.

[0071] The door assembly may include a door lock mechanism 300 and a drive mechanism 600. The drive mechanism 600 is connected to the door lock mechanism 300 in a transmission manner. The drive mechanism 600 is used to drive the door lock mechanism 300 to unlock. Multiple functional areas may include a door opening functional area 510.

[0072] The drive mechanism 600 can be a motor. The motor can be connected to the lever of the door lock mechanism 300 through the second link. One end of the second link can be fixedly connected to the output shaft of the motor, and the other end can be rotatably connected to the lever. The position where the second link and the lever are rotatably connected is different from the position where the first link and the lever are rotatably connected. The rotation of the motor can drive the lever to rotate through the second link.

[0073] The drive mechanism 600 can communicate with the door handle controller 710 via wiring harness 800, wireless connection, or Bluetooth connection. When the door opening function area 510 is triggered, the display device 500 transmits this signal to the door handle controller 710. The door handle controller 710 controls the drive mechanism 600 to start, and the door handle controller 710 transmits the signal that the door opening function area 510 is triggered to the central controller 720. The central controller 720 controls the vehicle to unlock. After the vehicle is unlocked, the door lock mechanism 300 of the door 100 unlocks, so that the door is in a state that allows it to be opened. After pressing the first end 210 to switch the door handle 200 to the extended state, pulling the door handle 200 in the direction of the vehicle outside can open the door 100.

[0074] In this situation, if the user forgets to bring the key or finds it inconvenient to take the key, the car door 100 can be opened by operating the display device 500 on the door handle 200. In addition, this way of opening the car door 100 can also improve the vehicle's security and anti-theft performance.

[0075] The multiple function areas may also include a start function area 520. After unlocking the display device 500 with a fingerprint, clicking the start function area 520 will trigger the start function area 520. When the start function area 520 is triggered, the door handle controller 710 will transmit the signal that the start function area 520 has been triggered to the central controller 720, and the central controller 720 will control the vehicle to start.

[0076] In this situation, the vehicle can be started from outside, without having to enter the car. This is especially suitable for scenarios where you need to quickly leave after a temporary stop (such as picking up luggage or after a short shopping trip), reducing the steps of getting in and out of the car and improving vehicle efficiency.

[0077] The door assembly may also include a window glass located on the door 100. The multiple functional areas may also include a window lifting function area 530. Clicking the window lifting function area 530 can trigger the window lifting function area 530. When the window lifting function area 530 is triggered, the door handle controller 710 transmits the signal that the window lifting function area 530 is triggered to the central controller 720, and the central controller 720 controls the movement of the window glass.

[0078] Optionally, when the central controller 720 detects that the window glass is in the closed state (the window glass is fully raised to the top, tightly fitted with the door frame, forming a closed cabin space), when the window lifting function area 530 is triggered, the central controller 720 can control the window glass to descend to switch to the open state (the window glass is partially or fully lowered, forming an opening with the door frame); when the central controller 720 detects that the window glass is in the open state, when the window lifting function area 530 is triggered, the central controller 720 can control the window glass to rise to switch to the closed state.

[0079] In this situation, the window glass can be raised and lowered from outside the vehicle. This way, if you remember that you left something in the car after getting out, you don't need to open the door. You can directly use the fingerprint unlock display device 500 to press the window lifting function area 530 to switch the window glass to the open state and take out the items from the car. Similarly, if you forget to close the window after getting out, you don't need to open the door. You can operate the display device 500 to switch the window glass to the closed state.
