Detailed Implementation

[0029] It should be noted that, unless otherwise specified, the embodiments and features described in the present invention can be combined with each other.

[0030] like Figure 1 and Figure 2 As shown, the seat support frame assembly is used in the non-driver's seat of the vehicle. It can support the seat cushion from the bottom and prevent the seat from sinking.

[0031] In the existing technology, the support frame assembly adopts one-piece stamped sheet metal. The structure of the support frame assembly needs to be designed according to the installation environment. The design structure is complex and the manufacturing process is difficult, resulting in high production costs, low strength of the support frame assembly, insufficient anti-submarine performance of the support frame assembly in the event of a collision, affecting vehicle safety. In addition, the overall structure of the support frame assembly is heavy, which affects the vehicle's lightweight design.

[0032] To address this, this invention provides a frame-type support skeleton assembly 100 composed of multiple tubular beams and multiple seat fixing brackets 2. This not only reduces the weight of the support skeleton assembly 100, ensuring the vehicle's lightweight performance, but also improves the strength of the support skeleton assembly 100 through structural changes, ensuring that the strength of the support skeleton assembly 100 meets the seat's anti-submarine function requirements, thus improving vehicle safety. Furthermore, it enables the platform-based design of the support skeleton assembly 100, reducing the manufacturing difficulty of the support skeleton assembly 100 and lowering the vehicle's production costs.

[0033] The following is for reference. Figures 1-8 A support frame assembly 100 according to an embodiment of the present invention is described.

[0034] The support frame assembly 100 according to an embodiment of the present invention may include: a support frame 1 and a plurality of seat fixing brackets 2.

[0035] Reference Figure 7 and Figure 8 As shown, the support frame 1 includes multiple tubular beams to reduce the overall mass of the support frame 1 while ensuring the overall strength of the support frame 1, thereby increasing the strength of the support frame assembly 100 and ensuring the lightweighting of the vehicle.

[0036] The support frame assembly 100 has a first direction and a second direction that are perpendicular to each other. Each tube beam extends along the first direction, and multiple tube beams are arranged along the second direction. Multiple seat fixing brackets 2 extend along the second direction and are spaced apart along the first direction. The tube beams and seat fixing brackets 2 together form a grid-like frame. The external force on the support frame assembly 100 can be evenly distributed on the grid-like frame formed by the tube beams and seat fixing brackets 2, ensuring that the support frame assembly 100 is subjected to uniform force. This ensures that the strength of the support frame assembly 100 meets the requirements of the seat for the anti-submersion function, thereby improving the safety of the vehicle.

[0037] The support frame 1 is installed on top of multiple seat fixing brackets 2. The support frame 1 is adapted to be installed on the bottom of the vehicle's seat cushion 300. The seat fixing brackets 2 are adapted to be fixed to the vehicle's floor assembly 200. Thus, the weight borne by the seat is transferred from the seat cushion 300 to the support frame 1 and evenly distributed to each tube beam. The tube beams then evenly distribute the force they receive to the seat fixing brackets 2 connected to them. The multiple tube beams transmit the force to different positions on the seat fixing brackets 2, ensuring that the force is evenly distributed on all parts of the seat fixing brackets 2 and ensuring the strength of the support frame assembly 100.

[0038] The support frame assembly 100 is composed of multiple tubular beams and multiple seat fixing brackets 2. While ensuring the strength of the support frame assembly 100, it avoids the structural redundancy caused by the whole plate structure, reduces the mass of the support frame assembly 100, and ensures the lightweight performance of the vehicle. Furthermore, the support frame assembly 100 is set between the floor assembly 200 and the seat cushion 300, so that the seat cushion 300 has sufficient support to keep it in a certain posture and meet the seat's anti-submersion function requirements.

[0039] Furthermore, since the support frame assembly 100 is composed of multiple tubular beams and multiple seat fixing brackets 2, it has the advantage of a platform-based structure, which reduces the manufacturing difficulty of the support frame assembly 100 and reduces the production cost of the vehicle.

[0040] According to an embodiment of the present invention, the support frame assembly 100 has a simple structure, low mass, and overall strength that meets the seat's anti-submersion function requirements, thus ensuring vehicle safety and lightweight performance.

[0041] In some embodiments, the support frame 1 may also include multiple beams with cross-sections of "I" shape, "U" shape, or other shapes, which are not limited here.

[0042] like Figure 3 and Figure 4 As shown, at least one tubular beam is fixedly connected to multiple seat fixing brackets 2, thereby transferring the weight of the seat from the seat cushion 300 to the tubular beam. The tubular beam can evenly distribute the force to the multiple seat fixing brackets 2 connected to it. The multiple seat fixing brackets 2 connected to the tubular beam can connect to and reinforce the tubular beam in the first direction, ensuring the strength and support performance of the tubular beam.

[0043] Reference Figure 3 and Figure 4 The supporting frame 1 includes a first tube beam 11, a second tube beam 12, and a third tube beam 13. The seat fixing bracket 2 includes four brackets. The first tube beam 11 is fixedly connected to each of the four seat fixing brackets 2. The second tube beam 12 is connected to each of the four seat fixing brackets 2. The third tube beam 13 is only connected to the two middle seat fixing brackets 2. Thus, by connecting the tube beams to the seat fixing brackets 2, the tube beams can be connected and reinforced by the seat fixing brackets 2, ensuring the strength and support performance of the tube beams, meeting the seat's anti-submersion function requirements, and ensuring vehicle safety.

[0044] In some embodiments, at least one tube beam is bent and extended to define a first portion 15 extending in a first direction and a second portion 16 extending in a second direction. The first portion 15 is fixedly connected to a plurality of seat fixing brackets 2, thereby increasing the contact area between the tube beam and the seat cushion 300, enabling the tube beam to better support the seat cushion 300, meeting the seat's anti-submersion function requirements, and ensuring vehicle safety.

[0045] Specifically, such as Figure 3 and Figure 4 As shown, the first tube beam 11 is disposed on one side of the seat fixing bracket 2 in the second direction, and its main body extends along the first direction. The first tube beam 11 bends on both sides in the first direction and extends to the other side of the seat fixing bracket 2 in the second direction, and its tail bends back and is fixedly connected to the seat fixing brackets 2 on both sides in the first direction.

[0046] A portion that bends away from the second tube beam 12 is also provided between the connection point of the first tube beam 11 and the seat fixing bracket 2, so as to increase the contact area between the tube beam and the seat cushion 300, so that the tube beam can better support the seat cushion 300, meet the seat's anti-submersion function requirements, and ensure the safety of the vehicle.

[0047] Reference Figure 3 and Figure 4 The vehicle support frame assembly 100 also includes a frame fixing bracket 3, which is fixed to the tube beam and adapted to be fixed to the seat cushion 300. Thus, the frame fixing bracket 3 can fix the seat cushion 300 to the support frame assembly 100 together, allowing the support frame assembly 100 to support the seat cushion 300 from below, ensuring the seat's anti-submarining performance.

[0048] like Figure 3 and Figure 4 As shown, there are multiple frame fixing brackets 3, one of which is fixedly connected to two adjacent tube beams. Thus, the frame fixing bracket 3 can be fixedly connected to the two adjacent tube beams to form a whole, making the overall strength higher. In addition, the frame fixing bracket 3 can connect and strengthen the tube beams, so that the tube beams can better support the seat cushion 300, meet the seat's anti-submersion function requirements, and ensure the safety of the vehicle.

[0049] like Figure 3 and Figure 4As shown, a frame fixing bracket 3 is provided between the first tube beam 11 and the second tube beam 12, and the frame fixing bracket 3 is located between two adjacent seat fixing frames. At the connection between the frame fixing bracket 3 and the first tube beam 11, the first tube beam 11 is bent away from the second tube beam 12 so that the frame fixing bracket 3 can have a larger force-bearing area, ensuring the overall strength and support performance of the support frame assembly 100.

[0050] A frame fixing bracket 3 is also connected between the two ends of the second tube beam 12, the seat fixing brackets 2 at both ends in the first direction, and the outwardly bent portions at both ends of the first tube beam 11. The frame fixing bracket 3 can connect the first tube beam 11, the second tube beam 12, and the seat fixing bracket 2 into a whole, making the overall strength higher.

[0051] In some embodiments, the connection point between the bends at both ends of the first tube beam 11 and the other end of the seat fixing bracket 2 in the second direction is flush with the connection point between the third tube beam 13 and the seat fixing bracket 2 in the first direction.

[0052] Furthermore, the seat fixing bracket 2 includes a first bracket 21 and a second bracket 22. The first bracket 21 is formed as an upwardly bent and protruding plate-like structure, which supports the tube beam in the height direction, thereby supporting the seat cushion 300 in the height direction, so that the seat cushion 300 can be supported and maintained at a certain angle, ensuring the seat's anti-submarining performance. The second bracket 22 is located at the bottom of the first bracket 21 and is fixedly connected to the two ends of the first bracket 21 to prevent the two ends of the first bracket 21 from moving due to insufficient support when subjected to force. The second bracket 22 can strengthen the first bracket 21, thereby making the overall strength higher and ensuring the seat's anti-submarining performance.

[0053] like Figure 3 As shown, the support frame assembly 100 also includes a reinforcing member 4, which is disposed on the second bracket 22. The reinforcing member 4, on the one hand, can cooperate with the second bracket 22 to form a cavity, thereby increasing the overall strength of the second bracket 22 and improving the overall strength of the support frame assembly 100. On the other hand, a portion of the reinforcing member 4 is clamped between the first bracket 21 and the second bracket 22, enhancing the strength at the connection between the first bracket 21 and the second bracket 22, ensuring the overall stability of the support frame assembly 100, and thus resulting in higher overall strength and ensuring the seat's anti-submersion performance.

[0054] In some embodiments, the reinforcing member 4 is only provided on the second bracket 22 on both sides in the first direction, so as to reduce the weight of the support frame assembly 100 while ensuring the overall strength, thereby ensuring the lightweight of the vehicle.

[0055] In other embodiments, the reinforcement 4 is provided on all of the second brackets 22 to meet the vehicle's higher strength requirements for the support frame assembly 100.

[0056] A vehicle according to another embodiment of the present invention includes a seat cushion 300, a floor assembly 200, and a support frame assembly 100 as described in the above embodiments, such as... Figures 5-8 As shown, the support frame 1 is fixed to the bottom of the seat cushion 300, which can support the seat cushion 300 at the bottom of the vehicle seat and prevent the seat from sinking.

[0057] Reference Figures 5-8 The bottom wall of the seat cushion 300 is provided with a receiving groove 301, and a part of the support frame 1 is accommodated in the receiving groove 301. The opening of the receiving groove 301 can reduce the weight of the seat cushion 300 and achieve vehicle lightweighting. In addition, the part of the support frame 1 is accommodated in the receiving groove 301, achieving double weight reduction. The receiving groove 301 can limit the support frame assembly 100 in the horizontal direction, ensuring the connection stability between the support frame assembly 100 and the seat.

[0058] like Figure 7 and Figure 8 As shown, the floor assembly 200 has a first chamber 207 located directly below the support frame assembly 100. In some embodiments, the floor assembly 200 includes: a middle floor 201, a seat front mounting reinforcement plate 202, a middle floor crossbeam 203, a crossbeam reinforcement plate 204, a seat rear mounting reinforcement plate 205, and a seat front mounting bracket 206.

[0059] A third chamber 101 is formed between the first support 21 and the second support 22, a fourth chamber is formed between the second support 22 and the middle floor 201, and a first chamber is formed between the middle floor 201 and the middle floor crossbeam 203. In some embodiments, a fifth chamber is formed between the reinforcing member 4 and the second support 22 between the third chamber and the fourth chamber. The first chamber, the third chamber, the fourth chamber and the fifth chamber can be stacked vertically to improve the strength of the support frame assembly 100, thereby improving the anti-submersion performance of the seat.

[0060] The seat front mounting bracket 206 is installed and fixed to the middle floor 201 below the connection point of the first bracket 21 and the second bracket 22 on the side away from the backrest in the first direction. A seat front mounting reinforcement plate 202 is provided below the middle floor 201 to ensure the stability of the connection between the seat and the floor assembly 200. A middle crossbeam reinforcement plate 204 is provided on the middle crossbeam 203 of the middle floor. A seat rear mounting reinforcement plate 205 is provided below the connection point of the second bracket 22 and the middle floor 201 on the side near the backrest in the first direction to ensure the stability of the connection between the seat and the floor assembly 200.

[0061] Reference Figure 8 The floor assembly 200 has a second chamber 208, and the first chamber 207 and the second chamber 208 are arranged in a first direction. Specifically, the middle floor longitudinal beam 209 extends along the first direction and connects with the middle floor 201 crossbeam. The second chamber 208 is formed between the middle floor 201, the middle floor longitudinal beam 209 and the middle floor 201 crossbeam. The second chamber 208 and the first chamber 207 are superimposed in the first direction to further enhance the strength of the support frame assembly 100, thereby improving the seat's anti-submersion performance.

[0062] The second cavity is located below the second support 22 in the middle of the plurality of second supports 22 to facilitate the overall structure setup.

[0063] Other components of a vehicle, such as the transmission, braking system, and steering system, are already known to those skilled in the art and are therefore not described in detail here.

[0064] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
