Description

Technical Field

[0001] This utility model relates to the field of automotive seat technology, specifically a stamped bracket for automotive seats. Background Technology

[0002] Car seats typically offer a variety of adjustment functions, such as fore-and-aft adjustment and backrest angle adjustment, to meet the different seating needs of passengers. These adjustments rely on a series of mechanical structures, among which the adjustment bracket is the component that connects and supports the seat's adjustment mechanism.

[0003] In the automotive seat manufacturing industry, traditional seat adjustment brackets often employ multi-part assembly methods using welding or bolting. Welding carries the risk of thermal deformation, easily leading to decreased assembly precision, while bolting poses a risk of loose threads, potentially causing lever displacement during prolonged vehicle travel and affecting the reliability of seat adjustment functions. Furthermore, existing bracket structures are typically composed of multiple independent components, increasing the number of parts and resulting in an overall heavier weight due to numerous welds or threaded connections, making it difficult to meet the lightweight design requirements of modern automobiles. To address the shortcomings of existing technologies, this invention provides a stamped bracket for automotive seats to solve the aforementioned problems. Utility Model Content

[0015] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions in the embodiments of this utility model are described clearly and completely. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0016] To better understand the above technical solutions, the following will provide a detailed explanation of the technical solutions in conjunction with the accompanying drawings and specific implementation methods.

[0017] This utility model discloses a stamped bracket for automobile seats, according to the attached... Figure 1-5 As shown, it includes a support base 1, a C-shaped mounting base 2 fixed on the support base 1, and a control lever 3 that is movably engaged within the C-shaped mounting base 2. The support base 1 and the C-shaped mounting base 2 are connected by an S-shaped corner piece 4, and the three components are designed as a single piece through stamping.

[0018] According to the appendix Figure 1 , 2 As shown in Figure 5, the bracket base 1 is a flat plate structure with mounting holes 11 and locating pins 12 welded onto its surface. The mounting holes 11 are used to bolt the internal components of the car seat, while the locating pins 12 are inserted into pre-drilled holes in the components to achieve insertion limit and ensure assembly accuracy. The C-shaped mounting base 2 is connected to the bracket base 1 via an S-shaped corner piece 4, forming a stable three-dimensional support frame. The arc-shaped bending structure of the S-shaped corner piece 4 can disperse stress, improve torsional strength, and adapt to the space of the installation position, thereby improving installation stability.

[0019] According to the appendix Figure 3 , 5 As shown, a U-shaped assembly groove 21 is opened on the top of the C-shaped mounting base 2, and stamping parts 22 are formed by extending on both sides of the groove. The two sets of end heads 32 of the control lever 3 are inserted into the assembly groove 21 for initial engagement. Vertical pressure is applied to the stamping parts 22 by the stamping equipment, causing plastic deformation and pressing the end heads 32 inward to achieve permanent mechanical locking. This assembly method is simple and reliable to operate, has low assembly difficulty, and good fastening after assembly, ensuring good stability of the bracket.

[0020] According to the appendix Figure 4 As shown, the control lever 3 has a bent part 31 in the middle and cylindrical end heads 32 at both ends. An annular anti-detachment groove 321 is formed on the surface of the end head 32. After the stamping part 22 is squeezed, it is embedded in the anti-detachment groove 321 to form a physical fitting structure to prevent the control lever 3 from axially detaching.

[0021] The working principle of this stamping bracket is as follows: Pre-assembly stage: The control lever 3 is bent to form the end head 32 and the bent part 31 of the control lever 3. The end head 32 of the control lever 3 is inserted into the assembly groove 21 of the C-shaped assembly seat 2 to form a movable snap-fit. Stamping and curing stage: The stamping die applies high pressure to the stamping part 22 of the C-shaped assembly seat 2, causing it to undergo plastic deformation and tightly wrap the end head 32. The deformed metal is embedded in the anti-dislodgement groove 321 to form a mechanical interlock. Functionality: The exposed bent portion 31 of the control lever 3 serves as the force application point, driving the seat adjustment mechanism through the lever principle.

[0022] The steps for using this stamping bracket are as follows: The two ends 32 of the control lever 3 are horizontally inserted into the assembly slots 21 of the C-shaped assembly seat 2; The stamping part 22 is stamped and fastened in one go using a special stamping equipment; Verify that the engagement between the control lever 3 and the stamping part 22 is secure; Align the positioning pin 12 of the bracket base 1 with the hole of the car seat component and insert it to limit the movement; Secure the bracket base 1 with bolts through mounting hole 11.

[0023] The beneficial effects of this stamping bracket are as follows: Highly efficient and stable connection: After the stamping part 22 is plastically deformed, it forms an irreversible mechanical lock with the anti-disengagement groove 321 of the end head 32 of the control lever 3. Compared with the traditional threaded connection, this connection method avoids the risk of thread loosening caused by vibration and impact during vehicle operation, greatly improving the stability and reliability of the connection, ensuring that the seat adjustment mechanism can work stably for a long time, and providing passengers with a safe and reliable riding environment.

[0024] Lightweight structure: The bracket base 1, C-shaped assembly base 2 and S-corner piece 4 adopt an integrated stamping design, which reduces welding points and additional assemblies.

[0025] Assembly error-proof design: The positioning pins 12 on the bracket base 1 cooperate with the mounting holes 11 to form a highly efficient assembly positioning system. During installation, the positioning pins 12 can quickly and accurately insert into the pre-drilled holes in the automotive seat components, achieving rapid and precise positioning of the stamped bracket and effectively preventing installation position deviations and component misassembly. This error-proof design greatly improves assembly efficiency, reduces assembly time and labor costs, and lowers quality problems and after-sales failure rates caused by assembly errors.

[0026] Low maintenance cost: The stamping and curing process replaces threaded connections, eliminating the risk of nuts falling off and reducing after-sales failure rate; High space utilization: The S-corner piece 4 adopts a compact transition design. Its arc-shaped bending structure not only effectively disperses stress and improves the torsional strength of the stamped bracket, but also better adapts to the installation space under the car seat. This design optimizes the space layout under the seat, providing more space for the installation and wiring of other components, making the overall design of the car seat more reasonable and compact.

[0027] The installation of the control lever 3 during the assembly of the stamping bracket is simple and intuitive. Simply insert the control lever 3 and end head 32 horizontally into the assembly slot 21 of the C-shaped mounting base 2, and then use a dedicated stamping machine to stamp and secure the stamping part 22 in one go. This assembly method is easy to operate, requires minimal technical skills from operators, ensures consistent and stable assembly quality, and improves production efficiency and product quality.
