[0037] The following reference Figures 1 to 4 This application describes the airtight sealing structure of the semi-concealed door handle arm in an embodiment.
[0038] according to Figures 1 to 4 As shown, an embodiment of this application's semi-concealed door handle swing arm airtight sealing structure includes a handle base plate 3, an aesthetic cover 4, a sealing gasket 2, and a handle body assembly 1. The aesthetic cover 4 is disposed on the handle base plate 3, and the sealing gasket 2 is disposed on the aesthetic cover 4. The aesthetic cover 4 has a first through hole 41, and the sealing gasket 2 has a second through hole 22. The first through hole 41 and the second through hole 22 are axially aligned, forming an integral hole channel. The handle body assembly 1 is mounted on the handle base plate 3 through the hole channel. The sealing gasket 2 abuts against the handle body assembly 1, ensuring an interference fit between the handle body assembly 1 and the sealing gasket 2, thus guaranteeing airtightness between the handle base plate 3 and the handle body assembly 1. This application, through a simple sealing structure, not only effectively prevents the ingress of water and dust, greatly reducing the jamming and failure rate caused by water ingress and dust accumulation, but also ensures the normal extension and retraction of the door handle under extreme weather conditions, such as heavy rain and severe cold, avoiding the risk of the door being unable to open due to icing or jamming. Meanwhile, the sealing structure of this application is easy to install, has a long-lasting and stable sealing effect, and has high weather resistance and durability, which significantly improves the reliability and service life of the door handle and provides users with a safer and more convenient user experience.
[0039] according to Figures 1 to 4 As shown, in one embodiment of this application, the sealing gasket 2 is provided with a protrusion 21, which abuts against the handle body assembly 1, so that the protrusion 21 and the handle body assembly 1 are in an interference fit. The protrusion 21 and the handle body assembly 1 form a tight contact, which can maintain a stable sealing effect during long-term use, prevent sealing failure caused by aging or deformation of the seal, and significantly extend the service life of the door handle system.
[0040] according to Figures 1 to 4 As shown, in one embodiment of this application, the sealing gasket 2 is mounted on the aesthetic cover 4 via a zip-lock connection structure. The zip-lock connection structure provides a stable fixing method, making the connection between the sealing gasket 2 and the aesthetic cover 4 tighter, preventing loosening or detachment due to vibration or external force during use. It also ensures better airtightness and protection during use, preventing external substances such as water and dust from entering the handle base plate 3 through the gap between the aesthetic cover 4 and the sealing gasket 2.
[0041] according to Figures 1 to 4 As shown, in one embodiment of this application, the aesthetic cover 4 is mounted on the handle base plate 3 via a snap-fit mechanism. This snap-fit and slot-based engagement eliminates the need for additional fasteners, allowing for quick and easy installation of the aesthetic cover 4 and handle base plate 3, simplifying the installation process and significantly improving assembly efficiency. Similarly, during later maintenance or replacement of the sealing ring assembly 6, the disassembly process is simple and quick, helping to shorten repair time and reduce maintenance costs.
[0042] In some embodiments, the aesthetic cover 4 is provided with a buckle, and the handle base plate 3 is provided with a slot. The aesthetic cover 4 is connected to the handle base plate 3 through the tight fit of the buckle and the slot. In other embodiments, the aesthetic cover 4 may also be provided with a slot, and the handle base plate 3 may be provided with a buckle.
[0043] according to Figures 1 to 4 As shown, in one embodiment of this application, the handle body assembly 1 includes a handle body 12 and a rotating arm 11. The handle body 12 and the rotating arm 11 are fixedly connected, and the rotating arm 11 is mounted on the handle base plate 3 through a hole channel. The rotating arm 11 is mounted through the hole channel, which not only evenly distributes the force generated during operation, but also ensures the smooth movement of the rotating arm 11 during opening and closing.
[0044] In some embodiments, the handle body 12 and the rotating arm 11 are integrated.
[0045] according to Figures 1 to 4As shown in one embodiment of this application, two of each of the first through hole 41, the second through hole 22, and the rotating arm 11 are provided. Each pair of first through holes 41 and corresponding second through holes 22 forms an independent hole channel. The handle body 12 is fixedly connected to the two rotating arms 11, and the two rotating arms 11 are respectively installed on the handle base plate 3 through their respective hole channels. The design of two hole channels and two rotating arms 11 enables the handle body 12 to achieve balanced force during installation, reducing local stress concentration, thereby improving the stability and impact resistance of the overall structure. The balanced force and stable fixing method enable the door handle to effectively resist the influence of the external environment during long-term use, extend the product's service life, and reduce structural damage caused by wear or fatigue.
[0046] according to Figures 1 to 4 As shown, in one embodiment of this application, the handle body assembly 1 further includes a handle cover 13, which is disposed on the upper part of the handle body 12. The handle cover 13 not only enhances the appearance of the handle body assembly 1, but also effectively prevents dust, moisture, and other external contaminants from contaminating the handle body 12, thereby improving the service life of the handle body assembly 1.
[0047] according to Figures 1 to 4 As shown, in one embodiment of this application, the semi-concealed door handle swing arm airtight sealing structure further includes a door sheet metal 5. The handle base plate 3 is disposed on the inner side of the door sheet metal 5, and the door sheet metal 5 surrounds the aesthetic cover 4, thereby realizing the concealed installation of the handle base plate 3.
[0048] according to Figures 1 to 4 As shown, in one embodiment of this application, the semi-concealed door handle swing arm airtight sealing structure further includes a sealing ring assembly 6. The sealing assembly is disposed between the door sheet metal 5 and the handle base plate 3. The handle base plate 3, the sealing ring assembly 6, and the aesthetic cover 4 are stacked sequentially. The sealing ring assembly 6 is disposed on the handle base plate 3, and the aesthetic cover 4 is disposed on the sealing ring assembly 6. The door sheet metal 5 is disposed around the periphery of the aesthetic cover 4, so that the handle base plate 3 and the sealing ring assembly 6 are concealed inside the door sheet metal 5. The sealing ring assembly 6 abuts against the door sheet metal 5, and the sealing ring assembly 6 and the door sheet metal 5 are interference-fitted to prevent water and dust from entering the partition between the handle base plate 3 and the door sheet metal 5, thus achieving the sealing of the outer ring of the door handle. The sealing ring assembly 6 abuts against the aesthetic cover 4, and the sealing ring assembly 6 and the aesthetic cover 4 are interference-fitted to prevent water and dust from entering the partition between the aesthetic cover 4 and the handle base plate 3, thus achieving the sealing of the inner ring of the door handle. The double-sealing design of the inner and outer rings not only effectively prevents water and dust from entering, greatly reducing the jamming and failure rate caused by water and dust accumulation, but also ensures that the door handle can extend and retract normally under extreme weather conditions, such as heavy rain and severe cold, avoiding the risk of the door being unable to open due to icing or jamming.
[0049] according to Figures 1 to 4 As shown, in one embodiment of this application, the sealing gasket 2 is made of rubber. The excellent flexibility of rubber makes it easy to achieve an interference fit during installation and maintain a stable state during daily use, facilitating replacement and maintenance, thereby improving the overall reliability of the product. Furthermore, the rubber material possesses excellent high-temperature and low-temperature resistance, enabling the sealing gasket 2 to continuously provide a stable sealing effect under various climatic conditions, ensuring that the door handle maintains good sealing performance even in extreme environments.
