Description

Technical Field

[0001] This invention belongs to the field of automotive door technology, and more specifically, relates to a semi-concealed door handle structure for automotive doors. Background Technology

[0002] Semi-concealed door handles are a popular design in the automotive industry, widely used, frequently used, and offering a high level of user experience. There are two main types of semi-concealed door handles: one type is mounted from the inside of the door cavity onto the outer reinforcement plate of the window frame. This type of handle has a complex structure, resulting in higher costs for both the handle and the door sheet metal. Furthermore, to ensure a tight seal, high precision is required in the manufacturing of the handle and door sheet metal, or the amount of sealing interference is increased. This large amount of sealing interference makes handle assembly difficult, and the surface difference between the handle and the outer door panel is difficult to guarantee in one assembly, often requiring secondary adjustments with tolerance adjusters, further complicating the assembly process. The other type of semi-concealed door handle is mounted from the outside of the door towards the inside, and then fixed to the outer door panel. This type of handle is lower in cost, but the sealing ring is prone to detachment, affecting assembly, or resulting in poor airtightness after assembly. Additionally, water accumulation at the sheet metal joints can lead to corrosion of the door sheet metal. The above issues will lead to serious customer complaints. Therefore, in developing semi-concealed door handles, it is particularly important to ensure sealing, wind noise, ease of assembly, corrosion resistance, and cost reduction while maintaining a good appearance. In summary, of the two existing semi-concealed external handle technologies, one is expensive and complex to assemble. The other is low-cost, but the sealing ring is prone to detachment, resulting in poor airtightness, difficulty in controlling surface differences, and water accumulation at the sheet metal edges, leading to rust on the door panel.

[0003] Existing technology includes a design entitled "A Rotary Electric Retractable Door Handle Structure" with publication number "115749481B". This technology belongs to the field of automotive parts and provides a rotary electric retractable door handle structure, comprising: a housing frame; a handle frame, one end of which is rotatably connected to the housing frame, and an unlocking part is provided at the lower end of the handle frame; an unlocking rod, which is movably disposed within the housing frame and connected to an external unlocking cable, and the unlocking rod movably abuts against one end of the unlocking part; and an actuating element, which is detachably disposed on one side of the housing frame, and the actuating element is provided with a drive shaft, the drive shaft movably abutting against the other end of the unlocking part. Compared with the prior art, the advantage of this invention is that the door handle is a retractable design, with the handle frame disposed inside the housing frame. When the handle frame is needed, one side of the handle frame rotates out from inside the housing frame, allowing the user to pull the handle frame to unlock and open the door. This design improves the overall aesthetics of the vehicle and reduces wind resistance during driving. This technology does not address the technical problems and solutions of this application.

[0014] The working principle and beneficial effects of the technical solution adopted in this invention are as follows: The semi-concealed door handle structure of the automobile door described in this invention features a fixed connection between the door handle opening handle 1 and the door handle movable arm 2. The movable arm 2 of the door handle opening handle 1 passes through the opening 4 of the door handle base 3. When the door handle opening handle 1 is activated, the movable arm 2 and the door handle opening handle 1 move synchronously, applying outward force to the door handle opening handle 1, opening the door. When the door handle opening handle 1 is released, it returns to its original position under the action of a return spring. During the opening or closing process, the movable arm 2 moves relative to the opening 4 of the door handle base 3. The door handle base 3 is mounted on the mounting hole plate 6 of the outer door panel 5, achieving a fixed connection between the door handle base 3 and the outer door panel 5. A protrusion 7 is provided on the outer ring of the door handle base 3, corresponding to the mounting hole plate 6. The protrusion 7 and the door handle base 3 are an integral structure, ensuring reliable overall structural strength and allowing for reliable placement of the sealing ring. The sealing ring can reliably withstand compressive force and will not easily detach. The protrusion 7 is provided with a first groove 8 and a second groove 9, which are positioned in different directions. This allows the first sealing ring 10 to connect to the protrusion 7 from different locations. When the first sealing ring 10 is subjected to external force, it can reliably withstand external forces from different directions, improving connection reliability. Both the first groove 8 and the second groove 9 are annular structures, arranged around the circumference of the protrusion 7. The first groove 8 and the second groove 9 are located on different surfaces of the protrusion 7. For example, the first groove 8 can be located on the upper surface of the protrusion 7, and the second groove 9 can be located on the inner surface of the protrusion 7. Since the first sealing ring 10 is annular, the sealing ring can be arranged and sealed around the circumference. The upper surface of the first sealing ring 10 is provided with a first hard lip 11, which is fitted into the first groove 8. The second hard lip 12 on the inner surface of the first sealing ring 10 is fitted into the second groove 9. The first sealing ring 10 and the protrusion 7 are reliably connected by the two-way fitting. The first sealing ring soft lip 13 extends outward from the outer door panel 5. The first sealing ring soft lip 13 of the first sealing ring 10 fits against the mounting hole plate 6 of the outer door panel 5. The contact between the first sealing ring soft lip 13 and the mounting hole plate 6 is achieved through the contact of the first sealing ring soft lip 13, so as to achieve the internal and external isolation of the door handle part at the opening 4 and ensure the reliable sealing of the gap. The opening 4 on the door handle base 3 is used for the door handle movable arm 2 to pass through. However, there will be a gap between the opening 4 and the door handle movable arm 2. Therefore, a second sealing ring 15 is set at the opening position. In order to reliably arrange the second sealing ring 15, a second sealing ring groove 14 is set on the surface of the opening 4 of the door handle base 3. The second sealing ring groove 14 is set around the opening. The second sealing ring hard lip 16 of the second sealing ring 15 is fitted into the second sealing ring groove 14. The second sealing ring soft lip 17 of the second sealing ring 15 fits against the door handle movable arm 2. The second sealing ring soft lip 17 extends outward toward the outer side of the door outer panel 5. In this way, the gap between the opening 4 and the door handle movable arm 2 is reliably sealed.Furthermore, the semi-concealed door handle structure of the automobile door of the present invention is provided with multiple sealing rings. The first sealing ring 10 is used to achieve the seal between the handle and the outer panel of the door, and the second sealing ring 15 is used to seal between the opening 4 of the handle and the movable arm 2 of the door handle.
