Description

Technical Field

[0001] This utility model relates to the field of automotive parts technology, specifically to a concealed door handle structure and vehicle. Background Technology

[0002] A car door handle is a device installed on the exterior and interior of a car body for opening or closing the car door. It is usually located on the side of the door, making it easy for passengers to grip and open the door to enter or exit the vehicle. The design of car door handles must meet functional requirements, such as ease of operation and ensuring safety, while also taking aesthetic factors into account to match the overall design style of the vehicle.

[0003] While traditional exposed manual door handles are intuitive and widely used, their protruding design from the outer surface of the door can negatively impact the streamlined aesthetics of the vehicle. Therefore, with the pursuit of higher aesthetic standards and functional improvements, traditional exposed door handles are gradually failing to fully meet market demands for exterior design. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide a hidden door handle structure and vehicle in light of the current state of the technology.

[0005] The technical solution adopted by this utility model to solve the above-mentioned technical problems is as follows: A concealed car door handle structure is proposed, comprising: a base, a drive arm, a driven arm, and a synchronizing rod. The car door handle is movably mounted on the base. The car door handle has a first end and a second end. The first end is rotatably connected to the drive arm, and the second end is rotatably connected to the driven arm. The drive arm and the driven arm are transmitted through the synchronizing rod. The car door handle has a retracted position, a flat position, and a maximum extended position on the base. The driven arm includes:

[0006] The first rotating block is rotatably connected to the base;

[0007] The second rotating block has one end rotatably connected to the synchronizing rod and the other end rotatably connected to the first rotating block;

[0008] The third rotating block has one end connected to the second end of the door handle, and the other end of the third rotating block is rotatably connected to the second rotating block;

[0009] The door handle structure includes a translational travel and an unlocking travel;

[0010] When in the translation stroke, the door handle can move because the first end of the door handle is driven by the drive arm, and the second rotating block and the third rotating block are driven by the synchronizing rod, so that the door handle can move between the retracted position and the extended position;

[0011] When the door handle is in the unlocking stroke, it can move away from the base due to the force on the second end. The second rotating block and the third rotating block drive the first rotating block to rotate, so that the door handle moves from the flat position to the maximum unfolded position.

[0012] The above-mentioned concealed door handle structure also includes a fourth rotating block, which is rotatably connected to the base and located on one side of the drive arm. The fourth rotating block is connected to the first rotating block through an unlocking link. An unlocking block is rotatably connected to the base, and one end of the unlocking block is rotatably connected to the unlocking link.

[0013] When in the unlocking stroke, the unlocking block can rotate relative to the base because the first rotating block rotates and drives the unlocking linkage to move on the base.

[0014] In the aforementioned concealed door handle structure, a first elastic element is provided between the unlocking link and the base. The first elastic element is used to reset the unlocking link after the external force applied to the second end of the door handle is removed.

[0015] The aforementioned concealed door handle structure also includes a counterweight block, which is rotatably connected to the base. A second elastic element is provided between the counterweight block and the base. One side of the synchronizing rod is provided with an outwardly extending locking post. The counterweight block is provided with a locking groove, and the locking post is movably disposed in the locking groove.

[0016] In the aforementioned concealed door handle structure, a third elastic element is provided between the drive arm and the base. The third elastic element is used to drive the drive arm to reset when the door handle moves from the extended position to the retracted position.

[0017] The aforementioned concealed door handle structure also includes:

[0018] A driver, comprising an output shaft to which a worm gear is connected;

[0019] A cam is rotatably connected to the base, a worm gear is provided on the cam, the worm meshes with the worm gear, and a rotating wheel is provided on the drive arm, which movably abuts against the cam.

[0020] In the aforementioned concealed door handle structure, a connecting groove is provided on the synchronizing rod, and a connecting part is provided on the first rotating block, the connecting part being movably engaged in the connecting groove.

[0021] This utility model solves the above-mentioned technical problems and also proposes a vehicle, including the above-mentioned hidden door handle structure.

[0022] Compared with the prior art, the advantage of this utility model is that the door handle position can be switched by the coordinated work of the drive arm, the synchronizing rod, the first rotating block, the second rotating block and the third rotating block: when not in use, the door handle can be stored close to the base to avoid protruding from the outer surface of the door, thereby enhancing the streamlined aesthetics of the vehicle's appearance.

[0031] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0032] like Figures 1 to 7 As shown, this solution mainly focuses on the application of this door handle structure in vehicles, and details its structure. These vehicles can be cars, trucks, vans, etc.

[0033] A concealed door handle structure includes: a base 1, a drive arm 2, a driven arm 3, and a synchronizing rod 4.

[0034] Specifically, the door handle 5 is movably mounted on the base 1. The door handle 5 has a first end 6 and a second end 7. The first end 6 is rotatably connected to the drive arm 2, and the second end 7 is rotatably connected to the driven arm 3. The drive arm 2 and the driven arm 3 are driven by a synchronizing rod 4. The door handle 5 has a retracted position, a flat position, and a fully extended position on the base 1. The driven arm 3 includes:

[0035] The first rotating block 8 is rotatably connected to the base 1;

[0036] The second rotating block 9 has one end rotatably connected to the synchronizing rod 4 and the other end rotatably connected to the first rotating block 8;

[0037] The third rotating block 10 has one end connected to the second end 7 of the door handle 5, and the other end of the third rotating block 10 is rotatably connected to the second rotating block 9.

[0038] The door handle 5 structure includes a sliding travel and an unlocking travel;

[0039] When in the translation stroke, the door handle 5 can move its first end 6 due to the drive arm 2, and drive the second rotating block 9 and the third rotating block 10 through the synchronizing rod 4, so that the door handle 5 can move between the retracted position and the flat position.

[0040] When in the unlocking stroke, the door handle 5 can move away from the base 1 due to the force on the second end 7. This causes the first rotating block 8 to rotate through the second rotating block 9 and the third rotating block 10, so that the door handle 5 moves from the flat position to the maximum unfolded position.

[0041] The rotational connection between the drive arm 2 and the base 1, and between the first rotating block 8 and the base 1, is preferably achieved via a pin. The rotation point between the drive arm 2 and the base 1 is defined as the first fixed rotation point 24, while the rotation point between the first rotating block 8 and the base 1 is defined as the second fixed rotation point 25. (Refer to...) Figure 1 and Figure 2 At this time, the door handle 5 is in the stowed position.

[0042] When the door needs to be opened, the drive arm 2 rotates around the first fixed rotation point 24, causing the first end 6 of the door handle 5 to move away from the base 1, that is, along... Figure 2 The movement proceeds from bottom to top. During the operation of the drive arm 2, through the linkage of the synchronizing rod 4, the second rotating block 9, and the third rotating block 10, the second end 7 of the door handle 5 also moves synchronously, thereby causing the entire door handle 5 structure to undergo a translational movement, ultimately moving to the position shown in the image. Figure 3 Flat out position shown.

[0043] Conversely, when the door handle 5 is in the extended position and the drive arm 2 rotates in the opposite direction around the first fixed rotation point 24, it will cause the first end 6 of the door handle 5 to move closer to the base 1. At the same time, the drive arm 2 causes the second rotating block 9 and the third rotating block 10 to move in the opposite direction through the synchronizing rod 4, thereby causing the second end 7 of the door handle 5 to move synchronously, so that the door handle 5 returns from the extended position to the extended position. Figure 2 The storage location is shown.

[0044] When the door handle 5 is in the extended position and its second end 7 is subjected to an outward force, this force is transmitted through the door handle 5 to the third rotating block 10, the second rotating block 9, and the first rotating block 8, causing the door handle 5 to move relative to the base 1 and driving the first rotating block 8 to rotate around the second fixed rotation point 25. This process causes the door handle 5 to enter the unlocking stroke until it reaches the desired position. Figure 4 Reach the maximum unfolded position shown to unlock the car door.

[0045] This solution utilizes the coordinated operation of the drive arm 2, the synchronizing rod 4, the first rotating block 8, the second rotating block 9, and the third rotating block 10 to achieve the switching of the position of the door handle 5: when not in use, the door handle 5 can be stored close to the base 1 to avoid protruding from the outer surface of the door, thereby enhancing the streamlined aesthetics of the vehicle's appearance.

[0046] This solution also includes a fourth rotating block 11, which is rotatably connected to the base 1 and located on one side of the drive arm 2. The fourth rotating block 11 is connected to the first rotating block 8 through an unlocking link 12. An unlocking block 13 is rotatably connected to the base 1, and one end of the unlocking block 13 is rotatably connected to the unlocking link 12. When in the unlocking stroke, the unlocking block 13 can rotate relative to the base 1 because the first rotating block 8 rotates and drives the unlocking link 12 to move on the base 1.

[0047] In this embodiment, the unlocking block 13 serves as a key structure for triggering the door lock to open. After the door handle 5 is moved to the extended position and its second end 7 is subjected to force, the door handle 5 drives the first rotating block 8 to rotate around the first fixed axis. When the first rotating block 8 rotates, it causes the unlocking block 13 to rotate around the third fixed rotation point 26 via the unlocking linkage 12. The rotation of the unlocking block 13 sends an unlocking command to the door lock, thereby realizing the door unlocking process.

[0048] The unlocking mechanism of unlocking block 13 can be implemented in one of two ways: one is to install a sensor inside the door, which is connected to the electronic lock circuit of the door. When unlocking block 13 rotates, the sensor detects this action and sends an unlocking signal to the electronic lock; the other way is to use a pull cable to connect unlocking block 13 and the latch pin of the door lock. In this way, when unlocking block 13 rotates, the pull cable will be tightened, thereby pulling the latch pin to complete the unlocking action.

[0049] A first elastic element is provided between the unlocking link 12 and the base 1. The first elastic element is used to reset the unlocking link 12 after the external force applied to the second end 7 of the door handle 5 is removed.

[0050] The first elastic element is preferably a spring, with hooks at both ends. One hook is fixed to the base 1, and the other is fixed to the unlocking link 12. When the first rotating block 8 drives the unlocking link 12, the unlocking link 12 not only drives the unlocking block 13 around the third fixed rotation point 26, but also stretches the spring, increasing the distance between the two hooks, thereby allowing the first elastic element (i.e., the spring) to store elastic potential energy. Once the external force acting on the door handle 5 is removed, the spring releases its stored elastic potential energy, thereby driving the unlocking link 12 and the unlocking block 13 connected to it back to the initial position, completing the reset action.

[0051] This solution also includes a counterweight 14, which is rotatably connected to the base 1. A second elastic element is provided between the counterweight 14 and the base 1. A locking post 15 extending outward is provided on one side of the synchronizing rod 4. A locking groove 16 is provided on the counterweight 14, and the locking post 15 is movably disposed in the locking groove 16.

[0052] The rotatable connection between the counterweight 14 and the base 1 can be achieved via a pin. During the rotation of the second rotating block 9 relative to the first rotating block 8 by the drive arm 2 via the synchronizing rod 4, the counterweight 14 applies resistance to the locking post 15 through its slot 16. This helps adjust the center of gravity position of the synchronizing rod 4, thereby making the movements of the drive arm 2 and the driven arm 3 more coordinated. The second elastic element disposed between the counterweight 14 and the base 1 is preferably a torsion spring. When the synchronizing rod 4 rotates the counterweight 14 relative to the base 1, the torsion spring stores elastic potential energy. When the door handle 5 moves from the extended position to the retracted position, the torsion spring releases the stored elastic potential energy, causing the counterweight 14 to return to its original position.

[0053] Preferably, a third elastic element is provided between the drive arm 2 and the base 1. The third elastic element is used to drive the drive arm 2 to reset when the door handle 5 moves from the flat position to the retracted position.

[0054] The third elastic element is preferably a torsion spring. This torsion spring is equipped with a first pin and a second pin, wherein the first pin is fixed to the drive arm 2, and the second pin is fixed to the base 1. When the drive arm 2 rotates relative to the base 1 around a first fixed rotation point 24, causing the door handle 5 to move from the retracted position to the extended position, the third elastic element (i.e., the torsion spring) stores elastic potential energy. When the drive arm 2 rotates in the opposite direction, causing the door handle 5 to return from the extended position to the retracted position, the third elastic element releases its stored elastic potential energy, thereby pushing the drive arm 2 to reset.

[0055] This solution also includes: a driver 17, which includes an output shaft 18, on which a worm gear 19 is connected; a cam 20, which is rotatably connected to the base 1, and a worm wheel 21 is provided on the cam 20, with the worm gear 19 meshing with the worm wheel 21; and a rotating wheel 22 is provided on the drive arm 2, with the rotating wheel 22 moving against the cam 20.

[0056] During operation, the cam 20 contacts the rotating wheel 22 on the drive arm 2, and by pushing the rotating wheel 22, the drive arm 2 rotates around the first fixed rotation point 24, thereby realizing the conversion of the door handle 5 between the retracted position and the extended position. The actuator is preferably a motor. When the motor is working, it drives the worm gear 19 to rotate by rotating the output shaft 18. When the worm gear 19 rotates, the worm wheel 21 meshing with it rotates accordingly, and transmits this rotational motion to the cam 20, thereby realizing the rotation of the cam 20.

[0057] Reference Figure 5 As shown, if the vehicle loses power and the actuator cannot move the door handle 5 out, the door can be opened manually with the key. The specific steps are as follows: Press the first end 6 of the door handle 5 to rotate the door handle 5 around the rotation center between the first end 6 and the drive arm 2, thereby popping out the second end 7 of the door handle 5; then hold the door handle 5 and continue to apply force until it is fully extended. Then, insert the key into the middle of the door handle 5, unlock it with the key, and complete the door opening action.

[0058] The synchronizing rod 4 is provided with a connecting groove 23, and the first rotating block 8 is provided with a connecting part 27. The connecting part 27 is movably engaged in the connecting groove 23. The connecting groove 23 and the connecting part 27 are provided to realize the connection between the synchronizing rod 4 and the first rotating block 8.
