[0002] With the rapid development of the automotive industry, many automotive parts are constantly being updated and replaced. Among automotive parts, seat pivot brackets are usually mounted on the seat crossbeam to provide support for the seat pivot. The seat backrest achieves angle adjustment through the seat pivot, facilitating passenger adjustment and meeting passenger comfort requirements. Current seat pivot brackets consist of more than five components connected by more than twenty sections of MIG welding. The large number of components results in low integration, hindering production efficiency and reducing structural strength at the weld points. Furthermore, the excessive number of components contributes to the weight of the seat pivot bracket, negatively impacting vehicle weight control. Utility Model Content

[0034] This utility model provides a seat pivot bracket, including a base 1, a bracket 2, and a cover plate 3. The base 1 includes a first base portion 11, a second base portion 12, and a third base portion 13. The second base portion 12 is integrally connected to the first base portion 11, and the bottom of the third base portion 13 is integrally connected to the top of the second base portion 12. The bracket 2 includes a first bracket portion 21 and a second bracket portion 22. The top of the first bracket portion 21 is integrally connected to the bottom of the second bracket portion 22. The cover plate 3 is detachably connected to the second bracket portion 22. The bottom of the first bracket portion 21 abuts against the top of the second base portion 12, and the bottom of the second bracket portion 22 abuts against the top of the third base portion 13. The first bracket portion 21 is located on one side of the third base portion 13 along the vehicle's transverse direction, and the first bracket portion 21 is connected to the third base portion 13.

[0035] Combination Figure 1 and Figure 2 As shown, the cover plate 3 and the second bracket portion 22 are detachably connected (e.g., by bolting, snap-fitting, plugging, etc.) to rotatably connect with the seat pivot 200, allowing the seat backrest to be adjusted for a different angle by rotating the seat pivot 200. The first base portion 11 and the seat crossbeam 100 can be connected by any method, such as bolting or welding. The second base portion 12 is integrally connected to the upper surface of the first base portion 11 (i.e., the surface along the positive Z-axis in the figure), and the bottom of the third base portion 13 (i.e., the part along the negative Z-axis in the figure) is integrally connected to the top of the second base portion 12 (i.e., the part along the positive Z-axis in the figure). In this embodiment, the third base portion 13 is located slightly to the left of the top of the second base portion 12 (i.e., slightly to the positive Y-axis), so that the first bracket portion 21 is located slightly to the right of the top of the second base portion 12. Thus, the first bracket portion 21 is located to the right of the third base portion 13 (i.e., the side along the negative Y-axis), and the bottom of the first bracket portion 21 abuts against the top of the second base portion 12 to form support.

[0036] Combination Figure 3As shown, in this embodiment, the top of the first support portion 21 is integrally connected to the bottom right side of the second support portion 22 (i.e., the position opposite to the Y-axis), so that the third base portion 13 is located at the bottom left side of the second support portion 22. In this way, the top of the third base portion 13 abuts against the bottom of the second support portion 22 to form support.

[0037] The third base portion 13 and the first support portion 21 can be connected by any means, such as bolt connection, welding, or pin connection, without any specific limitation.

[0038] The seat pivot bracket of this utility model is assembled with the seat pivot 200 by detachably connecting the cover plate 3 to the second bracket part 22. The second base part 12 is integrally connected to the first base part 11, the bottom of the third base part 13 is integrally connected to the top of the second base part 12, and the top of the first bracket part 21 is integrally connected to the bottom of the second bracket part 22. Compared with the traditional technology with more than five parts, this utility model mainly includes three parts (i.e., base 1, bracket 2, and cover plate 3), reducing the number of parts of the seat pivot bracket and integrating the original multiple parts into one, forming base 1 and bracket 2, thus improving the integration of the seat pivot bracket. This design improves production efficiency; the integrated connection method offers higher strength compared to traditional welding; the connection between the first bracket 21 and the third base 13, the bottom of the second bracket 22 abutting against the top of the third base 13, and the bottom of the first bracket 21 abutting against the top of the second base 12 enhance the stability of the connection between the bracket 2 and the base 1, thereby increasing the overall structural strength of the seat pivot bracket; the reduction in the number of parts lowers the weight of the seat pivot bracket, which helps control the weight of the car. The bracket 2 can be made using aluminum extrusion technology, and the base 1 can be made using aluminum casting technology, further reducing the weight of the seat pivot bracket.

[0039] Furthermore, the first support portion 21 includes a first outer frame structure 211 and a first reinforcing structure 212. The extension path of the first outer frame structure 211 corresponds to the edge of the third base portion 13. The top of the first outer frame structure 211 is integrally connected to the bottom of the second support portion 22. The bottom of the first outer frame structure 211 abuts against the top of the second base portion 12. The first reinforcing structure 212 is disposed on the inner side of the first outer frame structure 211 and is connected to the third base portion 13.

[0040] Combination Figures 1 to 5 As shown, the first outer frame structure 211, indicated by the dotted line in the figure, is a frame structure with a hollow center. Figure 2As can be seen, the first outer frame structure 211 corresponds to the edge of the third base portion 13, that is, the first outer frame structure 211 extends along the edge of the third base portion 13. The top of the first outer frame structure 211 is integrally connected to the bottom of the second support portion 22, and the bottom of the first outer frame structure 211 abuts against the top of the second base portion 12. The first reinforcing structure 212 is integrally disposed on the inner side of the first outer frame structure 211. The first reinforcing structure 212 and the third base portion 13 can be connected by means such as bolts, welding, or pins. The first outer frame structure 211 and the first reinforcing structure 212 constitute the first support portion 21, as shown below. Figure 4 and Figure 5 The first support portion 21 shown in this embodiment is made by an aluminum extrusion process (i.e., aluminum is extruded along the Y-axis direction in the figure).

[0041] Thus, the first support portion 21 is formed by the first outer frame structure 211 and the first reinforcing structure 212, which is more suitable for using aluminum extrusion process, so that the weight of the first support portion 21 is reduced while the structural strength is improved.

[0042] Preferably, the first reinforcing structure 212 includes a first columnar rib 2121 and a first strip rib 2122. For each first columnar rib 2121, at least two first strip ribs 2122 are provided around it. The first strip ribs 2122 extend radially around the first columnar rib 2121 until they are connected to the first outer frame structure 211.

[0043] Combination Figure 4 and Figure 5 As shown, the first columnar rib 2121 is cylindrical, and the first strip rib 2122 is elongated. In this embodiment, there are two first columnar ribs 2121. Seven first strip ribs 2122 are arranged around the first columnar rib 2121 near the positive direction of the Z-axis, and five first strip ribs 2122 are arranged around the first columnar rib 2121 near the negative direction of the Z-axis. The first strip ribs 2122 extend radially until they are integrally connected with the inner wall of the first outer frame structure 211. In this embodiment, a reinforcing strip rib is also provided to integrally connect two adjacent first columnar ribs 2121.

[0044] It is understood that the radial arrangement mentioned in this specification refers to multiple strip ribs extending from the column ribs in a direction away from the column ribs; the column ribs are preferably cylindrical, but can also be prismatic; the included angles between the strip ribs can be equal or unequal; the shape of the strip ribs can be straight or curved; the structure of the column ribs and strip ribs is not specifically limited in the preceding and following text, and can be designed according to actual needs.

[0045] Thus, the radial reinforcing ribs composed of the first columnar ribs 2121 and the first strip ribs 2122 enable the force to be transmitted to various parts through these reinforcing ribs, making the structure more uniformly stressed, improving the structural strength of the first outer frame structure 211, and thus improving the overall strength of the support 2.

[0046] Preferably, the third base portion 13 has a second outer frame structure 131 on one side edge away from the first support portion 21. The inner side of the second outer frame structure 131 has a second columnar rib 132 and a second strip rib 133. For each second columnar rib 132, at least two second strip ribs 133 are provided around it. The second strip ribs 133 extend radially around the second columnar rib 132 until they connect with the second outer frame structure 131.

[0047] Combination Figure 2 , Figure 3 , Figure 6 and Figure 7 As shown, the third base portion 13, on the side away from the first support portion 21, has a second outer frame structure 131 at its edge. Figure 7 The extension path of the second outer frame structure 131 is shown by dashed lines. Second columnar ribs 132 and second strip ribs 133 are disposed on the inner side of the second outer frame structure 131. In this embodiment, there are two second columnar ribs 132. Three second strip ribs 133 are arranged around one second columnar rib 132 near the positive Z-axis side, and three second strip ribs 133 are arranged around one second columnar rib 132 near the negative Z-axis side. A reinforcing strip rib connects the two second columnar ribs 132. The second columnar ribs 132 are connected to the second outer frame structure 131 by the second strip ribs 133 extending radially around them. It is understood that, unlike the first outer frame structure 211, the second outer frame structure 131 is disposed on the edge of the third base portion 13 and integrally formed with the third base portion 13, while the first outer frame structure 211, together with the first reinforcing structure 212, forms the first support portion 21. Figure 4 and Figure 5 The first support portion 21 shown is made by an aluminum extrusion process (i.e., aluminum is extruded along the Y-axis direction in the figure).

[0048] Thus, the third base part 13 is more suitable for manufacturing using the aluminum casting process, which is beneficial for weight reduction. The second outer frame structure 131, the second columnar rib 132, and the second strip rib 133 make the third base part 13 more uniformly stressed and have better structural strength.

[0049] Furthermore, the first columnar rib 2121 is provided with a first connecting hole 21211, and the second columnar rib 132 is provided with a second connecting hole 1321. The first columnar rib 2121 and the second columnar rib 132 are connected by a first connector 01 passing through the first connecting hole 21211 and the second connecting hole 1321.

[0050] Combination Figures 2 to 7 As shown, the first columnar rib 2121 is provided with a first connecting hole 21211, and the second columnar rib 132 is provided with a second connecting hole 1321. The first connecting member 01 is, for example, a bolt. The first connecting hole 21211 or the second connecting hole 1321 is provided with threads to cooperate with the bolt and connect the first columnar rib 2121 and the second columnar rib 132.

[0051] Thus, by setting the connection position of the first connector 01 on the first columnar rib 2121 and the second columnar rib 132, when the first connector 01 is subjected to force, the force can be transmitted to the surrounding structure through the columnar ribs (second columnar rib 132, first columnar rib 2121) and the strip ribs (first strip rib 2122, second strip rib 133), thereby improving the strength and rigidity of the connection position between the first support part 21 and the third base part 13.

[0052] Furthermore, the first base portion 11 includes a first base plate segment 111 and a second base plate segment 112. The first base plate segment 111 and the second base plate segment 112 are arranged at a first preset angle. The first base plate segment 111 is installed on the front wall of the seat crossbeam 100, and the second base plate segment 112 is installed on the top wall of the seat crossbeam 100.

[0053] Combination Figure 6 and Figure 7 As shown, the first base plate segment 111 and the second base plate segment 112 are integrally connected, and the first base plate segment 111 and the second base plate segment 112 are set at a first preset angle θ. In this embodiment, the first preset angle θ = 100°~130°. Combined with... Figure 1 As shown, the first base plate segment 111 can be installed and fixed to the front wall of the seat crossbeam 100 by means of bolt connection, riveting, etc., and the second base plate segment 112 can be installed and fixed to the top wall of the seat crossbeam 100 by means of bolt connection, riveting, etc. (The seat crossbeam 100 usually has a top wall, a front wall and a rear wall, which correspond to the side wall facing the positive Z-axis, the side wall facing the positive X-axis and the side wall facing the negative X-axis, respectively).

[0054] Thus, by means of the first preset angle between the first base plate segment 111 and the second base plate segment 112, the first base plate segment 111 and the second base plate segment 112 can be installed on the front wall and the top wall of the seat beam 100 respectively, which helps to improve the connection stability between the base 1 and the seat beam 100, thereby improving the support performance of the seat pivot bracket.

[0055] Preferably, the bottom of the second base portion 12 is disposed on the second base plate segment 112, and the second base portion 12 is provided with a first extension rib 121, which extends to the front side of the first base plate segment 111 and is integrally connected with the first base plate segment 111.

[0056] Combination Figure 6 and Figure 7 As shown, the bottom of the second base portion 12 is integrally connected to the second base plate segment 112. The front end of the second base portion 12 (i.e., one end along the positive X-axis) is provided with a first extension rib 121. The first extension rib 121 extends to the front side of the first base plate segment 111 (i.e., one side along the positive X-axis), thereby integrally connecting the first extension rib 121 with the first base plate segment 111.

[0057] Thus, the structural strength of the first base plate segment 111 and the second base plate segment 112 is improved by the first extension rib 121, and large deformation between the first base plate segment 111 and the second base plate segment 112 is avoided.

[0058] Furthermore, the top of the second base plate segment 112 is provided with a third outer frame structure 1121, and the second base portion 12 is integrally connected with the third outer frame structure 1121. The inner side of the third outer frame structure 1121 is provided with a third columnar rib 1122 and a third strip rib 1123. For each of the third columnar ribs 1122, at least two third strip ribs 1123 are provided around it. The third strip ribs 1123 extend radially around the third columnar ribs 1122 until they are connected to the third outer frame structure 1121 and / or the second base portion 12.

[0059] Combination Figure 6As shown, the top of the second base plate segment 112 (i.e., the side wall facing the positive Z-axis) is provided with a third outer frame structure 1121. The second base portion 12 and the third outer frame structure 1121 are integrally connected (in this embodiment, they can be made by aluminum casting process). The third columnar rib 1122 and the third strip rib 1123 are provided inside the third outer frame structure 1121. In this embodiment, there is one third columnar rib 1122, and six radial third strip ribs 1123 are provided around the third columnar rib 1122. The third strip ribs 1123 extend to be integrally connected with the third outer frame structure 1121, or they can be integrally connected with the second base portion 12, or they can be integrally connected with both the second base portion 12 and the third outer frame structure 1121 at the same time (i.e., extending to the connection position between the second base portion 12 and the third outer frame structure 1121).

[0060] Thus, the radial reinforcing ribs composed of the third columnar rib 1122 and the third strip rib 1123 enable the force to be transmitted to various parts through these reinforcing ribs, making the structure more uniformly stressed, improving the structural strength of the third outer frame structure 1121, and thus improving the overall strength of the base 1.

[0061] Furthermore, the top of the second base plate segment 112 is provided with a fourth outer frame structure 1124, and the second base portion 12 is integrally connected with the fourth outer frame structure 1124. The inner side of the fourth outer frame structure 1124 is provided with a fourth columnar rib 1125 and a fourth strip rib 1126. For each of the fourth columnar ribs 1125, at least two fourth strip ribs 1126 are provided around it. The fourth strip ribs 1126 extend radially around the fourth columnar ribs 1125 until they are connected to the fourth outer frame structure 1124 and / or the second base portion 12.

[0062] Combination Figure 7 As shown, the top of the second base plate segment 112 (i.e., the side wall facing the positive Z-axis) is provided with a fourth outer frame structure 1124. The second base portion 12 and the fourth outer frame structure 1124 are integrally connected (in this embodiment, they can be made by aluminum casting process). The fourth columnar rib 1125 and the fourth strip rib 1126 are provided inside the fourth outer frame structure 1124. In this embodiment, there is one fourth columnar rib 1125, and six radial fourth strip ribs 1126 are provided around the fourth strip rib 1126. The fourth strip rib 1126 extends to be integrally connected with the fourth outer frame structure 1124, or it can be integrally connected with the second base portion 12, or it can be integrally connected with both the second base portion 12 and the fourth outer frame structure 1124 at the same time (i.e., it extends to the connection position between the second base portion 12 and the fourth outer frame structure 1124).

[0063] Thus, the radial reinforcing ribs composed of the fourth columnar rib 1125 and the fourth strip rib 1126 enable the force to be transmitted to various parts through these reinforcing ribs, making the structure more uniformly stressed, improving the structural strength of the fourth outer frame structure 1124, and thus improving the overall strength of the base 1.

[0064] Optionally, combined Figure 2 , Figure 3 , Figure 6 and Figure 7 As shown, the third columnar rib 1122 has a third connecting hole 11221, and the fourth columnar rib 1125 has a fourth connecting hole 11251. Correspondingly, the top wall of the seat crossbeam 100 has a first mounting hole and a second mounting hole. The seat crossbeam 100 is connected to the third columnar rib 1122 by a second connector 02 passing through the third connecting hole 11221 and the first mounting hole, and the seat crossbeam 100 is connected to the fourth columnar rib 1125 by a third connector 03 passing through the fourth connecting hole 11251 and the second mounting hole. In this way, when the connection between the first base portion 11 and the seat crossbeam 100 is subjected to force, the force can be transmitted to the surrounding structure through the radial strip ribs, making the force distribution more uniform and improving the structural strength and rigidity of the base 1.

[0065] In this embodiment, the third outer frame structure 1121 and the fourth outer frame structure 1124 are preferably disposed on the right side and the left side of the second base portion 12 (i.e., the side opposite to the Y-axis and the side in the forward direction of the Y-axis). Compared with only one side of the outer frame structure and the reinforcing rib structure, this embodiment can enhance and reinforce both sides of the seat pivot bracket.

[0066] Furthermore, the second support portion 22 includes a fifth outer frame structure 221 and a fifth strip rib 222 disposed inside the fifth outer frame structure 221. Both ends of the fifth strip rib 222 are integrally connected to the fifth outer frame structure 221, and at least two fifth strip ribs 222 are intersected and connected to each other.

[0067] Combination Figure 4 and Figure 5 As shown, the fifth outer frame structure 221 and the fifth strip rib 222 constitute the second support part 22. The two ends of the fifth strip rib 222 are connected to any two different positions on the fifth outer frame structure 221, and multiple fifth strip ribs 222 are interconnected, such as... Figure 4 As shown, the included angle between the two intersecting fifth strips 222 can be designed as needed.

[0068] Thus, the fifth rib 222 strengthens the fifth outer frame structure 221. The fifth outer frame structure 221 and the fifth rib 222 are designed as a single unit and can be manufactured by aluminum extrusion process, which improves the integration of the seat pivot bracket.

[0069] Furthermore, the top of the fifth outer frame structure 221 is provided with a pivot groove 2211 and a first U-shaped hole 2212. The first U-shaped hole 2212 is located on both sides of the pivot groove 2211 along the transverse direction of the vehicle. The cover plate 3 is provided with a second U-shaped hole 31. The pivot groove 2211 is engaged with the end of the seat pivot 200. The first U-shaped hole 2212 and the second U-shaped hole 31 form a pivot through hole. The seat pivot 200 is rotatably connected in the pivot through hole.

[0070] Combination Figures 1 to 4 As shown, the top of the fifth outer frame structure 221 (i.e., the side of the fifth outer frame structure along the positive Z-axis) is provided with a pivot groove 2211, and the pivot groove 2211 is provided with first U-shaped holes 2212 on both sides of the vehicle's transverse direction (i.e., both sides along the positive and negative Y-axis), combined with Figure 8 As shown, the cover plate 3 is provided with two second U-shaped holes 31 corresponding to two first U-shaped holes 2212. The end of the seat shaft 200 can be engaged in the shaft slot 2211. The shaft of the seat shaft 200 extends out from the shaft through hole formed by the first U-shaped hole 2212 and the second U-shaped hole 31, thereby rotatably connecting with the shaft through hole.

[0071] Thus, the first U-shaped hole 2212 and the second U-shaped hole 31 form a rotating shaft through hole, so that when the end of the seat rotating shaft 200 is engaged in the rotating shaft slot 2211, the seat rotating shaft 200 is rotatably connected to the rotating shaft through hole, thereby realizing the assembly of the seat rotating shaft 200.

[0072] Furthermore, the inner surface of the fifth outer frame structure 221 is provided with a protrusion 2213, the fifth outer frame structure 221 is provided with a first hook portion 2214 and a fifth connecting hole 2215, the fifth connecting hole 2215 extends into the protrusion 2213, the cover plate 3 is provided with a sixth connecting hole 32 and a second hook portion 33, the first hook portion 2214 is engaged with the second hook portion 33, and the cover plate 3 is connected to the fifth outer frame structure 221 by a fourth connector 04 passing through the fifth connecting hole 2215 and the sixth connecting hole 32.

[0073] Combination Figures 1 to 5 As shown, a protrusion 2213 is provided on the inner surface of the fifth outer frame structure 221, such as... Figure 4As shown, the protrusion 2213 is integrally connected to the fifth outer frame structure 221. The entire support 2, including the first support portion 21 and the second support portion 22, can be manufactured using an aluminum extrusion process. A fifth connecting hole 2215 is provided on the fifth outer frame structure 221 at a position corresponding to the protrusion 2213, so that the fifth connecting hole 2215 extends into the protrusion 2213. A sixth connecting hole 32 is provided on the cover plate 3. The cover plate 3 is connected to the fifth outer frame structure 221 by a fourth connector 04 (a bolt in this embodiment) passing through the fifth connecting hole 2215 and the sixth connecting hole 32. Figure 4 and Figure 5 As shown, the fifth outer frame structure 221 is also provided with a first hook part 2214, and the cover plate 3 is provided with a second hook part 33. The first hook part 2214 and the second hook part 33 can be locked together.

[0074] Thus, by engaging the first hook portion 2214 with the second hook portion 33 and connecting the cover plate 3 and the fifth outer frame structure 221 with the fourth connector 04, the cover plate 3 and the second bracket portion 22 are detachably connected, facilitating the assembly of the seat pivot 200.

[0075] This utility model also provides a vehicle including the aforementioned seat pivot bracket.

[0076] The vehicle of this utility model uses the aforementioned seat pivot bracket to achieve the rotation adjustment function of the seat back. Assembly with the seat pivot 200 is achieved through a detachable connection between the cover plate 3 and the second bracket part 22. The second base part 12 is integrally connected to the first base part 11, the bottom of the third base part 13 is integrally connected to the top of the second base part 12, and the top of the first bracket part 21 is integrally connected to the bottom of the second bracket part 22. Compared to conventional designs with five or more components, this utility model mainly includes three components (i.e., base 1, bracket 2, and cover plate 3), reducing the number of components in the seat pivot bracket and integrating multiple original components into one, forming base 1 and bracket 2, thus improving efficiency. The increased integration of the seat pivot bracket improves production efficiency. The integrated connection method offers higher strength compared to traditional welding. Furthermore, the connection between the first bracket part 21 and the third base part 13, the bottom of the second bracket part 22 abutting against the top of the third base part 13, and the bottom of the first bracket part 21 abutting against the top of the second base part 12 enhance the stability of the connection between the bracket 2 and the base 1, thereby increasing the overall structural strength of the seat pivot bracket. The reduced number of parts lowers the weight of the seat pivot bracket, which helps control the weight of the vehicle. The bracket 2 can be made using aluminum extrusion, and the base 1 can be made using aluminum casting, further reducing the weight of the seat pivot bracket.
