Description

Technical Field

[0001] This utility model relates to the field of automotive parts, and in particular to a door handle structure. Background Technology

[0002] Door handles are crucial components in automobiles used for opening doors. Their structural design not only affects ease of use but also influences the overall aesthetics, aerodynamics, and safety of the vehicle. Interior door handles are essential operating components for occupants to open doors from inside the vehicle. They are typically installed on the inner armrest area of ​​the front and rear doors, positioned ergonomically for easy and natural reach. While their structure is simpler than external handles, they still incorporate several key components to ensure smooth, safe, and reliable operation.

[0003] Currently, most car interior door handles use screws to connect the trim frame and base. This requires pre-drilled screw holes and countersunk holes in both the frame and base, and sometimes additional space to install nuts or stud brackets. This connection method not only increases the number of parts but also demands higher assembly precision, leading to a cumbersome assembly process. Some car interior door handles use a one-piece molding of the trim frame and base, saving space for fasteners. However, disassembly is more difficult during maintenance, requiring the removal of the entire door panel housing assembly, which can easily damage the assembly and lead to unnecessary parts replacement.

[0031] Example: Figure 1-9The diagram shows a door handle structure, comprising: a door handle housing assembly 1 and a handle device 2. The door handle housing assembly 1 includes a trim frame 101 and a base 102, and the handle device 2 is disposed between the trim frame 101 and the base 102; a locking interface 121, which is provided on the side of the base 102; and a buckle 111, which is fixedly connected to the side of the trim frame 101. The buckle 111 engages with the locking interface 121, significantly reducing manual operation time and assembly steps, resulting in higher assembly efficiency. Compared to traditional screw connections, the buckle 111 connection eliminates the need for pre-drilled screw holes, countersunk holes, and nut space, making the overall structure more compact. For door panel areas with limited interior space, this further helps optimize the interior layout and achieve weight reduction. Compared to a one-piece molded housing assembly, when the door handle needs maintenance or replacement of parts, no destructive disassembly is required; the buckle 111 can be separated from the locking interface 121, effectively improving maintainability. The base 102 is provided with positioning posts 206, and the positioning posts 206 are provided with reinforcing ribs 261. The positioning posts 206 and reinforcing ribs 261 control the limiting of their respective directions to achieve the assembly and positioning of the base 102 and the inner door panel. The base 102 has several holes around its perimeter, and screws pass through the holes to fix it to the inner door panel. The handle device 2 includes a handle 201 and a pivot pin 202. The pivot pin 202 passes through the handle 201 and connects to the base 102. The pivot pin 202 is provided with a torsion spring 203. The base 102 is provided with a pivot pin mounting part 122. The handle 201 is provided with a mounting lug 211. The mounting lug 211 is located on the rear side of the handle 201. The mounting lug 211 is provided with a hole, and the pivot pin 202 passes through the hole of the mounting lug 211 and connects to the pivot pin mounting part 122. The mounting lug 211 has a traction part 212, which is located at the end away from the hole of the mounting lug 211. Pulling the handle 201 causes the handle 201 to rotate around the axis of the shaft pin 202 via the mounting lug 211 through the rotation of the torsion spring 203 and the shaft pin 202. After releasing the handle 201, it automatically resets via the torsion spring 203. A cover plate 204 is located between the handle 201 and the base 102, and the cover plate 204 is connected to the base 102. Several fixing buckles 241 are fixedly connected to the cover plate 204, and the fixing buckles 241 are located at the perimeter of the cover plate 204. Several fixing grooves 124 are provided on the base 102, and the fixing grooves 124 engage with the fixing buckles 241. A plurality of positioning buckles 242 are fixedly connected to the cover plate 204, and a plurality of positioning grooves 125 are provided on the base 102. The positioning grooves 125 are matched and engaged with the positioning buckles 242. A buffer member 205 is disposed between the handle 201 and the base 102.The base 102 has a buffer mounting part 123, and the buffer 205 is installed in the buffer mounting part 123. The buffer 205 effectively prevents the handle 201 from generating impact noise during the reset and rebound process, thus improving the user experience.

[0032] The handle 201 has two grooves that are connected to each other in the middle, forming a continuous finger groove structure. The user can pass his finger through the connected area and pull it away from the base 102 to open the car door.

[0033] The base 102 has a lead wire groove at its rear end for holding the control wire that pulls the door switch via the handle 201. In use, pulling the handle 201 causes the mounting lug 211 to rotate 49° around the axis of the pin 202 via the pin 202 and the torsion spring 203. During the rotation, the traction part 212 moves, and the control wire cooperates with the traction part 212. The movement of the traction part 212 drives the movement of the control wire to open the door.

[0034] The surfaces of the frame 101 and handle 201 are electroplated, while the surfaces of the base 102 and cover plate 204 are treated with black texture for a better appearance.
