Detailed Implementation

[0037] To enable those skilled in the art to more clearly understand this application, the technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0038] Please see Figures 1-6 The first aspect of this application provides a concealed door handle, including a base 2, a handle cover 1, a sensing module 9, a controller, and an actuator:

[0039] The base 2 is provided with a receiving cavity 21 for accommodating the handle cover 1. The base 2 is provided with a handle part 211, which is located in the receiving cavity 21. The handle part 211 is provided in the receiving cavity 21 near the outer surface of the door.

[0040] The handle cover 1 is rotatably connected to the base 2, allowing it to switch between a closed and an open state. In the open state, the handle cover 1 exposes the handle portion 211. The handle cover 1 can rotate around the base 2 into the receiving cavity 21. The handle cover 1 can be opened by flipping it from bottom to top or from top to bottom. The handle cover 1 is normally in the closed state, flush with the outer surface of the door, achieving both aesthetics and a sealing effect. The handle cover 1 can be manually pushed to rotate or electrically driven to rotate, thus changing the handle cover 1 from the closed state to the open state.

[0041] The sensing module 9 is mounted on the base 2 and is capable of sensing the movement of the handle 211.

[0042] The sensor module 9 is electrically connected to the controller and is used to send a trigger signal to the controller when the handle 211 is sensed. When a person's fingers grip the handle 211, the sensor module 9 is triggered, and the sensor module 9 sends a trigger signal to the controller. The sensor module 9 can be a pressure sensor or a fingerprint acquisition and recognition module. When using a pressure sensor, it sends a trigger signal to the controller when it senses the pressure of a person's hand gripping the handle. When using a fingerprint acquisition and recognition module, it sends a trigger signal to the controller after successfully acquiring and matching the fingerprint of the driver or passenger.

[0043] The controller is electrically connected to the actuator and is used to send an unlocking signal to the actuator in response to the trigger signal;

[0044] An actuator, used to unlock the door in response to an unlocking signal from the controller, is connected to a power supply assembly, which includes a main vehicle power supply and a backup power supply. The backup power supply is connected in parallel with the main vehicle power supply and then connected to the actuator to supply power to it. Under normal circumstances, the actuator is powered by the main vehicle power supply; when the main vehicle power supply is unavailable, the backup power supply is activated, and the circuit of the backup power supply is connected to the actuator to supply power.

[0045] The concealed door handle proposed in this application embodiment allows the handle cover 1 to rotate inward around the inner wall of the receiving cavity 21 to expose the handle portion 211. When a person's fingers grip the handle portion 211, the sensing module 9 is simultaneously triggered. The sensing module 9 transmits a trigger signal to the controller, which sends an unlocking signal to the actuator to control the actuator to unlock. Pulling the handle portion 211 then opens the door. Even when the vehicle's main power supply is unavailable, the actuator can still be powered by a backup power supply to open the door. Furthermore, the inward rotation of the handle cover 1 around the inner wall of the receiving cavity 21 reduces the size along the width of the vehicle body when the handle cover 1 is opened, and also avoids the risk of a push-type handle colliding with other parts during movement.

[0046] In some embodiments, the concealed door handle further includes a handle mounting structure. The handle cover 1 is provided with a connecting seat 11, and the connecting seat 11 is provided with a first through hole 111. The handle mounting structure includes a rotating plate 4, a first rotating shaft 5, and a resetting member 6. The rotating plate 4 is rotatably connected to the inner wall of the receiving cavity 21, and the rotating plate 4 is provided with a first mounting hole 42. The first rotating shaft 5 is fixedly installed in the first mounting hole 42 and passes through the first through hole 111. The resetting member 6 is connected to the handle cover 1 and the rotating plate 4 respectively. When the electric drive handle cover 1 is not required, a person can push the edge of the handle cover 1 away from the first rotating shaft 5 with their hand, causing the handle cover 1 to move inward around the first rotating shaft 5. After the handle cover 1 has moved a certain distance under the action of the person's hand, the person's fingers can touch the handle part 211. When the person's fingers grasp the handle part 211, the sensing module 9 is triggered. The sensing module 9 sends a trigger signal to the controller, and the controller controls the actuator to unlock. The person can open the car door through the handle part 211. When the person's hand is taken out of the receiving cavity 21, the reset member 6 can reset the handle cover 1 to the closed state without the force of the person's hand. The closed state is flush with the outer surface of the car door, achieving the functions of aesthetics and sealing.

[0047] In some implementations, such as Figure 3 As shown, the first mounting hole 42 is located at the upper part of the receiving cavity 21, the handle cover 1 opens by flipping from bottom to top, and the handle part 211 is located at the lower part of the receiving cavity 21. The handle cover 1 opens by flipping from bottom to top, and when a person pulls the handle part 211, their palm faces down, which is more in line with people's usage habits and makes it easier to pull the door.

[0048] In other embodiments, the first mounting hole 42 is located at the lower part of the receiving cavity 21, the handle cover 1 is opened by flipping from top to bottom, and the handle portion 211 is located at the upper part of the receiving cavity 21. The handle cover 1 is opened by flipping from bottom to top, so that when a person pulls the handle portion 211, the back of their hand is facing down, and the car door can still be opened.

[0049] Of course, in some other embodiments, the handle cover 1 can also be opened by flipping from left to right or from right to left.

[0050] In some embodiments, a spring sleeve shaft 12 is provided on the side of the connecting seat 11, and the spring sleeve shaft 12 is sleeved on the first rotating shaft 5; the reset member 6 includes a reset spring 63, a first spring-loaded member 61, and a second spring-loaded member 62; the reset spring 63 is sleeved on the outside of the spring sleeve shaft 12, and its two ends are respectively connected to the first spring-loaded member 61 and the second spring-loaded member 62; the first spring-loaded member 61 is installed on the first snap-fit ​​part 41, which is disposed on the rotating plate 4, and the first snap-fit ​​part 41 can be a slot, and the first spring-loaded member 61 is embedded in the first snap-fit ​​part 41; the second spring-loaded member 62 is installed on the second snap-fit ​​part 13, which is disposed on the handle cover 1. During the process of manually pushing the handle cover 1 to rotate and open, the reset spring 63 deforms to generate a rebound force. When the force of the manual push disappears, the handle cover 1 returns to the closed state under the action of the rebound force of the reset spring 63, and the closed state is flush with the outer surface of the door. There are two connecting seats 11 and reset pieces 6, arranged symmetrically to achieve a balancing effect.

[0051] In some embodiments, the rotating plate 4 is provided with a second mounting hole 43. The handle mounting structure also includes a second rotating shaft 3, a transmission mechanism 7, and a drive device 8. The second rotating shaft 3 is fixedly installed in the second mounting hole 43. The transmission mechanism 7 is connected to the second rotating shaft 3 and is used to drive the second rotating shaft 3 to rotate. The drive device 8 is connected to the transmission mechanism 7 and is electrically connected to the controller. The drive device 8 can be a motor. The drive device 8 is fixed on the base 2 and drives the second rotating shaft 3 to rotate through the transmission mechanism 7, thereby driving the rotating plate 4 to rotate together, so as to drive the return spring 63 and the connecting seat 11 connected to the rotating plate 4 and the handle cover 1 to rotate together. The controller controls the forward and reverse rotation of the drive device 8 to realize the opening and closing of the handle cover 1.

[0052] In some embodiments, the transmission mechanism 7 includes a driving gear 71 and a driven gear 72 that mesh with each other. The driving gear 71 is connected to the drive device 8, and the driven gear 72 is connected to the second rotating shaft 3. The forward rotation of the drive device 8 drives the driving gear 71 to rotate, which in turn drives the driven gear 72 and the second rotating shaft 3 to rotate together, thereby opening the handle cover 1. Similarly, reversing the drive device 8 closes the handle cover 1. The driving gear 71 can be a full-tooth gear, and the driven gear 72 can be a sector gear. Since the driving gear 71 and driven gear 72 can only drive the handle cover 1 to rotate when meshed, the rotation angle of the handle cover 1 is controlled by the size of the sector arc angle of the sector gear, ensuring that the handle cover 1 can only rotate within a specified angle range, thus improving the reliability of the device. A sector gear is a gear with angled tooth surfaces on its circumference. It can be divided into two types: internally convex and externally convex. The tooth surfaces of internally convex sector gears are curved inwards, while those of externally convex sector gears are curved outwards. This embodiment uses an externally convex sector gear. Sector gears offer several advantages: their angled design increases torque output and improves the efficiency of mechanical equipment; they can perform high-power transmission tasks within a limited space; and they effectively detect noise generated during mechanical operation. By employing a large gear for the driving gear 71 and a small gear for the driven gear 72, the angular velocity of the driven gear 72 can be increased, allowing for faster electric opening and closing of the handle cover 1 and enhancing the user experience for drivers and passengers.

[0053] In some embodiments, the concealed door handle also includes an opening check switch 10, which is disposed in the receiving cavity 21. When the handle cover 1 is opened to a preset angle, it presses against the contact of the opening check switch 10. In response to the pressure of the handle cover 1, the opening check switch sends a stop signal to the controller. The controller controls the drive device 8 to stop operating according to the stop signal. By setting the opening check switch 10, the opening angle of the handle cover 1 is consistent each time it is in the open state. By setting the position of the opening check switch 10, the opening angle of the handle cover 1 is made convenient for a person to reach into the receiving cavity 21 and grasp the handle part 211. Moreover, the opening angle of the handle cover 1 can be precisely limited to avoid damage caused by excessive rotation angle of the handle cover 1, thereby improving the reliability of the device.

[0054] In some embodiments, the bottom of the base 2 is provided with a drain hole 22. The drain hole 22 allows water entering the receiving cavity 21 to drain out through the drain hole 22, keeping the receiving cavity 21 dry, improving the user experience for drivers and passengers, and at the same time avoiding the risk of short circuits to the electronic components in the handle.

[0055] The working principle of this concealed door handle is:

[0056] 1. Manual mode: A person can push the edge of the handle cover 1 away from the first rotating shaft 5 with their hand, and push the handle cover 1 to move inward around the first rotating shaft 5. After the handle cover 1 has moved a certain distance under the action of the hand, the fingers of the person can touch the handle part 211. The person can pull the handle through the handle part 211. When the handle cover 1 is no longer under the action of the hand, the reset part 6 can reset the handle cover 1 to the closed state. The closed state is flush with the outer surface of the door, achieving the functions of aesthetics and sealing.

[0057] II. Electric Mode: The controller controls the drive device 8 to rotate forward, driving the active gear 71 to rotate, which in turn drives the driven gear 72 to rotate. This causes the second rotating shaft 3 and the driven gear 72 to rotate together, thereby causing the rotating plate 4, which is fixedly connected to the second rotating shaft 3, to rotate. This, in turn, causes the return spring 63, the connecting seat 11, and the handle cover 1, which are connected to the rotating plate 4, to rotate together until the handle cover 1 presses against the contact of the open / check switch 10. At this point, the controller stops the drive device, and the handle cover 1 is in the open state. Similarly, by controlling the drive device 8 to rotate in reverse, the handle cover 1 can be put in the closed state.

[0058] The concealed door handle proposed in this application embodiment allows for both electric and manual opening and closing. Even when the electric mode is not desired or the main power supply is unavailable, the door can still be opened manually. This solves the problem in existing concealed door handles where the handle cover 1 can only be opened electrically, making it impossible to open the door when the electric mode is not desired or the main power supply is unavailable. Unlike existing designs where the handle cover 1 is pushed outwards or flipped outwards, this concealed door handle features an inward-flipping structure. In the closed state, the handle cover 1 is flush with the outer surface of the door. In both closed and open states, the handle cover 1 is retracted into the receiving cavity 21. This not only effectively saves space in the width direction of the vehicle body and increases design flexibility but also effectively reduces wind resistance. The structure in the above embodiment requires use with an electrically released door lock.

[0059] In some other embodiments, the sensing module 9 can be replaced with a mechanical unlocking structure to work with a mechanical lock, further saving costs. The unlocking operation is completed by manually pulling the handle 211, which, in conjunction with the mechanical unlocking structure.

[0060] In a second aspect of this application, a vehicle door is provided, including a door body and a concealed door handle as described in the first aspect. A base 2 is connected to the door body, and a handle cover 1 is flush with the door body. In this embodiment, the handle cover 1 is normally in a closed state, flush with the outer surface of the door, achieving both aesthetics and a sealing effect. Even when the vehicle's main power supply is unavailable, a backup power supply can still power the actuators to open the door. Furthermore, the handle cover 1 rotates inward around the inner wall of the receiving cavity 21, reducing its dimension along the vehicle's width when opening, and simultaneously avoiding the risk of a push-type handle colliding with other parts during movement.

[0061] In a third aspect of this application, a vehicle is provided, including the door described in the second aspect. The vehicle proposed in this application uses the door of the second invention, which can still supply power to the actuators via a backup power source to open the door even when the vehicle's main power supply is unavailable. The door is convenient to open and aesthetically pleasing.
