[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0030] It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0031] The present invention will be further described below with reference to the accompanying drawings and specific embodiments, but this is not intended to limit the present invention.

[0032] This utility model provides an integrated window lift switch box 8 and inner handle panel assembly, which is installed on the interior door panel, as shown in the reference. Figures 1-7 It includes: decorative panel strip 2, decorative panel 1, handle 3, handle panel 4, pivot 5, torsion spring 6, buffer pad 7 and glass lifting switch box 8;

[0033] The decorative panel 1 is provided with a first mounting hole 101, and the decorative panel strip 2 passes through the first mounting hole 101 and is snapped and fixed to the mounting structure 102 on the decorative panel 1.

[0034] The handle 3 is provided with a second mounting hole 301, and the decorative panel 1 passes through the second mounting hole 301 and engages with the first hook structure 302 built into the handle 3;

[0035] The handle 3 is provided with a symmetrical third mounting hole 303, and the handle panel 4 is provided with a corresponding fourth mounting hole 401. The rotating shaft 5 passes through the fourth mounting hole 401, the torsion spring 6 and the third mounting hole 303 in sequence to pivotally connect the handle 3 to the handle panel 4. One end of the torsion spring 6 abuts against the handle panel 4 and the other end abuts against the handle 3 to provide a reset torque.

[0036] The handle panel 4 has a fifth mounting hole 402, through which the glass lifting switch box 8 passes and engages with the second hook structure 405 built into the handle panel 4; the handle panel 4 has a sixth mounting hole 403, into which the buffer pad 7 is embedded; the handle panel 4 also has several connecting holes 404 for fixing electroplated decorative parts, interior panels and inner sheet metal.

[0037] Specifically, the decorative panel strip 2 can pass through the first mounting hole 101 on the decorative panel 1 and be snapped into the mounting structure 102 inside the decorative panel 1. This snap-fit ​​method is not only convenient to install, but also has a stable connection, effectively reducing the problem of decorative parts shifting due to loose screws in traditional installation methods. The handle 3 is provided with a second mounting hole 301. The decorative panel 1 uses its own structure to pass through the second mounting hole 301 and snap into the built-in slot 305 of the handle 3. The built-in slot 305 is also provided with a limiting rib 306, so that the decorative panel 1 and the first hook structure 302 inside the handle 3 can be snapped into each other. This connection method cleverly avoids the use of additional fasteners, simplifies the assembly steps, and ensures a tight connection between the handle 3 and the decorative panel 1. The handle 3 and the handle panel 4 are respectively provided with symmetrical third mounting holes 303 and fourth mounting holes 401. The pivot 5 passes through the fourth mounting hole 401, the torsion spring 6 and the third mounting hole 303 in sequence, so that the handle 3 can pivot around the pivot 5. The torsion spring 6 abuts against the handle panel 4 and the handle 3 at both ends, providing a reset torque for the handle 3. This design ensures that the handle 3 can automatically reset after use, improving the convenience and reliability of operation. The handle panel 4 has a sixth mounting hole 403, into which a buffer pad 7 is embedded. The buffer pad 7 effectively reduces impact noise when the handle 3 resets, improving the user experience. The handle panel 4 also has several connecting holes 404 for fixing electroplated decorative parts, interior panels, and inner sheet metal. The design of these connecting holes 404 allows for quick positioning and installation of various components, further simplifying the assembly process.

[0038] This integrated design integrates functional components such as the window lift switch box 8, the inner handle, and decorative parts into one unit through a reasonable structural layout and connection method. The snap-fit ​​fixing of the decorative panel strip 2 and the decorative panel 1, as well as the hook connection between the handle 3 and the decorative panel 1, realizes the rapid assembly of parts. The cooperation between the pivot 5 and the torsion spring 6 ensures the smooth operation of the handle 3 and the reliability of the reset. The setting of the buffer pad 7 effectively solves the problem of abnormal noise from the reset impact, improves the overall quality of the vehicle. By reducing the number of independent parts, the utilization of the interior space of the door is optimized, and the assembly process is greatly simplified through connection methods such as snap-fit ​​and hook.

[0039] Decorative panel strip 2 and decorative panel 1 are assembled together into the hook structure of handle 3, and the free end of decorative panel 1 is inserted into the second mounting hole 301 and engaged with the first hook structure 302 built into handle 3, thus completing the assembly of decorative panel strip 2 and decorative panel 1 on handle 3. This assembly method allows decorative panel strip 2 and decorative panel 1 to be tightly combined to form a unified whole and play a decorative role together. At the same time, decorative panel 1 can be stably assembled on handle 3 with the help of decorative panel strip 2, ensuring structural stability and facilitating later installation and use.

[0040] The rotating shaft 5 has a knurled structure on its surface and is fixed to the fourth mounting hole 401 of the handle panel 4 by riveting. The knurling structure is formed on the surface of the rotating shaft 5 by machining, usually using a knurling tool on a lathe. This structure increases the friction between the rotating shaft 5 and the fourth mounting hole 401, preventing unnecessary rotation or displacement of the rotating shaft 5 during use. The knurling structure of the rotating shaft 5 is located at both ends, and after riveting, it forms anti-detachment flanges with a diameter larger than the mounting hole. When the rotating shaft 5 is inserted into the fourth mounting hole 401 of the handle panel 4, the knurled section is in close contact with the hole wall. Riveting tools are used to rivet both ends of the rotating shaft 5, causing the knurled section to plastically deform and form anti-detachment flanges with a diameter larger than the mounting hole, preventing the rotating shaft 5 from falling off.

[0041] The glass lift switch box 8 engages with the second hook structure 405 of the handle panel 4 via multiple fifth mounting holes 402, forming a circumferential limit. During installation, align the glass lift switch box 8 with the fifth mounting holes 402 of the handle panel 4, and insert the glass lift switch box 8 into the fifth mounting holes 402 until the second hook structure 405 engages with the edge of the fifth mounting hole 402, forming a secure connection. The cooperation of the multiple fifth mounting holes 402 and the second hook structure 405 restricts the glass lift switch box 8 circumferentially (i.e., in the direction of rotation around the pivot 5). This design, through multiple engagement points, disperses and bears possible circumferential forces, preventing the glass lift switch box 8 from rotating or misaligning during use, ensuring its operational accuracy and stability.

[0042] The buffer pad 7, made of rubber, is positioned along the reset path of the handle 3 to eliminate impact noise. When the handle 3 resets after operation, it contacts the buffer pad 7. The rubber buffer pad 7 absorbs the kinetic energy of the handle 3 during reset through its elastic deformation, converting it into heat or potential energy. This effectively reduces the direct impact between the handle 3 and the handle panel 4. This energy conversion process significantly reduces impact noise and improves the quietness and comfort of operation. The installation position of the buffer pad 7 corresponds to the reset position of the handle 3. The positioning of the sixth mounting hole 403 needs to be determined based on the range of motion and reset path of the handle 3 to ensure that the buffer pad 7 is precisely on the reset trajectory of the handle 3. When the external force is removed, the handle 3 returns to its initial position with the help of the reset torque of the torsion spring 6. The rubber buffer pad 7 effectively absorbs the kinetic energy of the handle 3 through its elastic deformation characteristics, reducing its reset speed and thus mitigating or even eliminating the impact force between the handle 3 and the panel, achieving a noise reduction effect.

[0043] The handle panel 4 is equipped with a spring-loaded nut for connecting the metal reinforcing sheet metal to the handle panel 4. The design of the spring-loaded nut allows the connection between the metal reinforcing sheet metal and the handle panel 4 to withstand greater tensile and shear forces, enhancing the overall structural strength. Even under vibration and impact during vehicle operation, the spring-loaded nut can maintain the bolt's tightness, preventing the connection from loosening.

[0044] The handle 3 is equipped with a cable interface 304 for connecting the door lock cable to achieve mechanical unlocking of the door lock. When the handle 3 is pulled, the handle 3 drives the door lock cable to move through the cable interface 304, thereby triggering the unlocking action of the door lock mechanism and achieving mechanical unlocking of the car door.

[0045] The torsion spring 6 is formed by a winding process, with pins at both ends, which are respectively attached to the surfaces of the handle panel 4 and the handle 3. When the handle 3 is pulled, the torsion spring 6 undergoes torsional deformation and stores elastic potential energy. When the handle 3 is released, the elastic potential energy of the torsion spring 6 is released, driving the handle 3 to return to its initial position, thus realizing the automatic reset function.

[0046] Implementation Principle: First, the decorative panel strip 2 is passed through the first mounting hole 101 of the decorative panel 1 and secured with the mounting structure 102 inside the decorative panel 1. Then, the decorative panel 1 is passed through the second mounting hole 301 of the handle 3 and secured in the built-in slot 305 of the handle 3, and secured with the first hook structure 302. The limiting rib 306 in the slot enhances connection stability. The rotating shaft 5 is passed sequentially through the fourth mounting hole 401 of the handle panel 4, the torsion spring 6, and the third mounting hole 303 of the handle 3 to complete the pivotal installation of the handle 3, ensuring that both ends of the torsion spring 6 abut against the handle panel 4 and the handle 3 respectively to provide reset torque. The glass lifting switch box 8 is passed through the fifth mounting hole 402 of the handle panel 4 and secured with the built-in second hook structure 405. Finally, a rubber buffer pad 7 is embedded in the sixth mounting hole 403 of the handle panel 4, ensuring it is positioned on the reset path of the handle 3. Using the connection holes 404 on the handle panel 4, the electroplated decorative parts, interior panels and inner sheet metal are fixed to the handle panel 4 by fasteners.

[0047] The above are merely preferred embodiments of the present utility model and are not intended to limit the implementation methods and protection scope of the present utility model. Those skilled in the art should realize that any equivalent substitutions and obvious changes made based on the description and illustrations of the present utility model should be included within the protection scope of the present utility model.
