Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0027] Example 1

[0028] Please see Figures 1-4As shown, an interior door handle assembly for automobiles includes a handle body 1: a composite mounting base 2 is fixedly connected to the front end of the handle body 1, a transmission rod 3 is fixedly connected to the top end of the inner cavity of the handle body 1, a return spring 4 is movably connected to one end of the transmission rod 3, decorative covers 5 are fixedly connected to both ends of the transmission rod 3, a locking key 6 is fixedly connected to the inner cavity of the handle body 1, a limit block 7 is fixedly connected to the inner cavity of the handle body 1, a connecting pivot 8 is fixedly connected to the inner cavity of the handle body 1, a sealing gasket 9 is fixedly connected to the inner cavity of the handle body 1, and a sensor contact 10 is fixedly connected to the inner cavity of the handle body 1.

[0029] Furthermore, the handle body 1 has an ergonomic arc-shaped structure with multiple grooves on its surface for easy gripping, and one end of it is connected to the connecting pivot 8.

[0030] When in operation, when the person inside the vehicle needs to open the door, they hold the handle body 1. Because the handle body 1 has an ergonomic arc structure and multiple easy-to-grip grooves on the surface, it can provide a comfortable and stable grip experience. The user applies force to pull or rotate the handle body 1, and rotates it around the connecting pivot 8.

[0031] Furthermore, the composite mounting base 2 is a plate-shaped structure with multiple mounting holes and reinforcing ribs around the mounting holes for fixing the handle assembly.

[0032] Furthermore, the transmission rod 3 is a slender rod-shaped structure, with one end movably connected to the rotation center of the handle body 1;

[0033] During operation, the handle body 1 rotates, driving the connected transmission rod 3 to move. The transmission rod 3 is a slender rod-shaped structure, with one end movably connected to the rotation center of the handle body 1. This connection method allows the transmission rod 3 to flexibly transmit the movement of the handle body 1. The transmission rod 3 transmits the pulling or rotating force of the handle to the unlocking mechanism of the car door, thereby realizing the unlocking action of the car door.

[0034] Furthermore, the return spring 4 is a helical spring structure, with one end fixed to the fixed part of the handle assembly and the other end connected to the handle body 1;

[0035] When in operation, after the handle body 1 is operated, the return spring 4 plays a role. The return spring 4 is a helical spring structure, with one end fixed to the fixed part of the handle assembly and the other end connected to the handle body 1. When the handle body 1 is pulled or rotated, the return spring 4 generates elastic force, so that the handle body 1 returns to the initial position, preparing for the next operation.

[0036] Furthermore, the decorative cover 5 has a shell-like structure adapted to the handle assembly and covers the outside of the handle assembly;

[0037] During operation, the decorative cover 5 has a shell-like structure that fits the handle assembly and covers the outside of the handle assembly. During the operation of the handle, the decorative cover 5 not only beautifies the appearance, but also prevents dust and debris from entering the handle assembly, protecting internal components such as the transmission rod 3 and the return spring 4, and extending the service life of the handle assembly.

[0038] Furthermore, the locking button 6 is a button-type structure, located in an easily accessible position on the handle assembly, and is used to control the handle body 1;

[0039] When in operation, if there are special needs inside the vehicle, such as when a child is inside, the locking button 6 can be operated. The locking button 6 is a button-type structure and is located in an easily accessible position on the handle assembly. After pressing the locking button 6, it will restrict the movement of the handle body 1, preventing it from being pulled or turned, thereby preventing accidental opening of the door and ensuring the safety of the people inside the vehicle.

[0040] Furthermore, the limiting block 7 is a block structure, installed on the rotation path of the handle assembly, and its side near the rotation trajectory of the handle body 1 is arc-shaped, used to limit the rotation angle of the handle body 1.

[0041] During operation, the limiting block 7 is a block-shaped structure installed on the rotation path of the handle assembly. The side of it closest to the rotation trajectory of the handle body 1 is arc-shaped. When the handle body 1 rotates, the limiting block 7 will limit its rotation angle to prevent the handle body 1 from rotating excessively and causing collisions or damage to other components, thus ensuring the normal operation and service life of the handle assembly.

[0042] Furthermore, the connecting pivot 8 is a cylindrical structure that rotatably connects the handle body 1 to other parts of the handle assembly, allowing the handle body 1 to rotate around it.

[0043] Furthermore, the sealing gasket 9 is a ring-shaped sheet structure, which is installed at the connection between the handle assembly and the door interior panel or other areas where gaps may occur;

[0044] During operation, the sealing gasket 9 is a ring-shaped sheet structure, which is set at the connection between the handle assembly and the door interior panel or other places where gaps may occur. During vehicle operation, it can effectively prevent dust, moisture and other substances from entering the vehicle, keeping the interior environment clean and dry, and also helps to improve the sound insulation effect inside the vehicle. When the user's hand approaches or touches the sensor 10, the sensor 10 will detect the signal. For example, the sensor 10 can be connected to the vehicle's keyless entry system or interior lighting system. After detecting the touch signal, it will automatically unlock the door or turn on the interior lighting, improving the user's convenience.

[0045] Working Principle: The car door opening handle assembly achieves door opening and related auxiliary functions through the coordinated work of various components. The handle body 1, as the operating component, utilizes an ergonomic design for easy gripping and force application by the user. The connecting pivot 8 allows the handle body 1 to rotate flexibly, converting the user's operation into mechanical motion. The transmission rod 3 is responsible for transmitting the movement of the handle body 1 to the door unlocking mechanism to complete the unlocking action. The return spring 4 uses its own elasticity to provide a restoring force for the handle body 1, ensuring that the handle can return to its initial state after operation for easy use next time. The decorative cover 5 and sealing gasket 9 respectively ensure the normal operation environment of the handle assembly from the aspects of appearance protection and sealing and dust prevention. The locking button 6 and the limit block 7 prevent misoperation and excessive operation from the perspective of safety and structural protection. The sensor contact 10 realizes intelligent function expansion and improves the user experience.
