[0024] The following is for reference. Figures 1-6 The present invention describes a seat frame assembly 100 according to an embodiment of the present invention. The seat frame assembly 100 has high assembly precision, high assembly efficiency, low development cost, and wide applicability.

[0025] like Figures 1-6 As shown, a seat frame assembly 100 according to an embodiment of the present invention includes: a seat cushion frame 1 and a lower connecting plate 2.

[0026] The seat cushion frame 1 and the backrest frame 3 are the core support parts of the seat. The seat cushion frame 1 is mainly used to bear the weight of the human body and distribute the pressure, while the backrest frame 3 is mainly used to support the human back, maintain the correct sitting posture, and protect the upper body in the event of a collision. Through the cooperation of the seat cushion frame 1 and the backrest frame 3, a comfortable riding experience is provided to the user.

[0027] The seat cushion frame 1 is provided with a positioning part 11, which is used to achieve precise and rapid pre-positioning between the seat cushion frame 1 and the lower connecting plate 2. The lower connecting plate 2 is a structural component of the angle adjuster assembly. The lower connecting plate 2 is used to rotatably connect with the backrest frame 3, that is, the lower connecting plate 2 and the backrest frame 3 can rotate relative to each other, so that the angle adjuster assembly can drive the backrest frame 3 to rotate through the lower connecting plate 2, thereby realizing the adjustment of the angle of the backrest frame 3 to meet the usage needs of different users.

[0028] The lower connecting plate 2 is provided with a positioning and mating part 21, which is adapted to the positioning part 11. The positioning and mating part 21 and the positioning part 11 can cooperate with each other to achieve precise and rapid pre-positioning between the seat frame 1 and the lower connecting plate 2, so that the connection between the lower connecting plate 2 and the seat frame 1 is aligned, ensuring assembly efficiency and assembly accuracy. No manual calibration is required, making the assembly between the seat frame 1 and the lower connecting plate 2 more convenient.

[0029] Furthermore, the seat frame 1 and the lower connecting plate 2 are adapted to be detachably connected via the first connecting member 4 after the positioning part 11 and the positioning mating part 21 are positioned and mated.

[0030] In other words, after the positioning part 11 and the positioning mating part 21 cooperate with each other, the precise relative position between the seat frame 1 and the lower connecting plate 2 is fixed, that is, the precise and fast pre-positioning is achieved. Then, the seat frame 1 and the lower connecting plate 2 can be connected quickly and accurately through the first connecting member 4, thereby completing the firm connection between the seat frame 1 and the lower connecting plate 2, so that the seat frame 1 and the lower connecting plate 2 are connected into an integral structure.

[0031] The first connector 4 can be constructed as a bolt, screw, nut, pin, buckle, rivet, hook, or protrusion, so that the seat frame 1 and the lower connecting plate 2 can be connected by threads, plugs, or snaps, thus realizing a detachable connection between the seat frame 1 and the lower connecting plate 2, which is flexible, convenient, and facilitates quick connection and disassembly of the lower connecting plate 2 and the seat frame 1.

[0032] In practice, the positioning part 11 is a component with a specific shape or structure. For example, the positioning part 11 can be constructed as a positioning protrusion, a positioning post, a positioning flange, a positioning buckle, a positioning pin, etc. The positioning mating part 21 is adapted to the shape and size of the positioning part 11. For example, the positioning mating part 21 can be constructed as a positioning recess, a positioning groove, a positioning hole, a positioning slot, etc. In this way, the precise fit between the positioning part 11 and the positioning mating part 21 is realized, thereby realizing the precise positioning between the seat frame 1 and the lower connecting plate 2.

[0033] In addition, the positioning part 11 and the positioning mating part 21 have a simple structure, occupy little space, will not affect the installation of the first connecting part 4, are easy to manufacture, have low manufacturing costs, and have a high degree of universality. They are conducive to achieving modularization and platformization, reducing the development cost of the entire seat frame assembly 100, and have a wide range of applications.

[0034] According to the embodiment of the present utility model, the seat frame assembly 100 is provided with a positioning part 11 on the seat cushion frame 1 and a positioning mating part 21 on the lower connecting plate 2. Through the positioning mating of the positioning part 11 and the positioning mating part 21, the pre-positioning between the seat cushion frame 1 and the lower connecting plate 2 is achieved. Then, the seat cushion frame 1 and the lower connecting plate 2 can be quickly and accurately detachably connected through the first connecting member 4, thereby improving assembly efficiency and assembly accuracy. Moreover, the positioning part 11 and the positioning mating part 21 have a simple structure, occupy little space, and will not affect the installation of the first connecting member 4. They are easy to manufacture, have low manufacturing cost, and high universality. They are conducive to modularization and platformization, reduce the development cost of the entire seat frame assembly 100, and have a wide range of applications.

[0035] In some embodiments, one of the positioning part 11 and the positioning mating part 21 is configured as a positioning flange and the other is configured as a positioning groove, wherein the positioning flange extends into the positioning groove and is limited to the inner wall of the positioning groove.

[0036] In other words, the positioning part 11 can be constructed as a positioning flange, and the positioning mating part 21 can be constructed as a positioning groove. Alternatively, the positioning part 11 can be constructed as a positioning groove, and the positioning mating part 21 can be constructed as a positioning flange, with the shape and size of the positioning flange matching the positioning groove. In this way, during actual assembly, the positioning flange can smoothly extend into the positioning groove and press against the inner wall of the positioning groove, so that the positioning flange and the inner wall of the positioning groove mutually limit each other, thereby achieving the limiting fit between the positioning flange and the positioning groove. This achieves precise pre-positioning between the seat frame 1 and the lower connecting plate 2, preventing the relative position between the seat frame 1 and the lower connecting plate 2 from shifting, which would make it difficult to install the first connecting piece 4.

[0037] In a specific embodiment, such as Figure 2 and Figure 3 As shown, the seat cushion frame 1 is provided with a positioning part 11, which is constructed as a positioning flange. The lower connecting plate 2 is provided with a positioning and fitting part 21, which is constructed as a positioning groove. At least a portion of the positioning flange extends into the positioning groove, and the upper surface of the positioning flange can press against the inner wall of the positioning groove. The front and rear sides of the positioning flange can press against the inner wall of the positioning groove. Of course, the upper surface and the front and rear sides of the positioning flange can also be spaced slightly apart from the inner wall of the positioning groove to facilitate the smooth insertion and extension of the positioning flange into and out of the positioning groove, reduce friction, and thus achieve a limiting fit between the positioning flange and the positioning groove, restricting the positioning flange from moving forward, backward, and upward relative to the positioning groove, that is, restricting the lower connecting plate 2 from moving forward, backward, and downward, thereby restricting the relative movement between the lower connecting plate 2 and the seat cushion frame 1, and achieving precise pre-positioning between the lower connecting plate 2 and the seat cushion frame 1.

[0038] In actual design, the positioning flange can be set as a rectangular flange, L-shaped flange, T-shaped flange, circular flange, irregular flange, etc., and the positioning groove can be a rectangular positioning groove, V-shaped positioning groove, U-shaped positioning groove, dovetail positioning groove, irregular positioning groove, etc. The specific shape of the positioning flange and positioning groove in this embodiment is not limited and can be flexibly set according to the actual situation and needs, and is not limited to the one described in this embodiment.

[0039] In some embodiments, the positioning groove is provided at the edge of the lower connecting plate 2 and is constructed as a notch groove.

[0040] In other words, a portion of material is removed from a location area at the edge of the lower connecting plate 2 to form a groove, which is called a notch. One side of the notch can be open and have a certain depth so that the positioning flange can extend into the notch along the depth direction and engage with the inner wall of the notch. Alternatively, the notch can be a closed groove so that the positioning flange can extend into the notch along the thickness direction and engage with the inner wall of the notch.

[0041] Among them, reference appendix Figure 1 As shown, Figure 1 As shown in the center direction, the positioning groove can be set at the lower edge, upper edge, front edge, rear edge, or other edge of the lower connecting plate 2. It can be flexibly set according to the actual situation and is not limited to the one described in this embodiment.

[0042] In actual design, a notch or groove can be punched out at the edge of the lower connecting plate 2, which is convenient for manufacturing.

[0043] In other embodiments, the positioning flange is bent and connected to the seat cushion frame 1.

[0044] Therefore, the positioning flange can be bent and extended relative to the seat frame 1 in the direction of the positioning groove, which is conducive to the positioning flange extending into the positioning groove to fit with the inner wall of the positioning groove.

[0045] Specifically, such as Figure 1 and Figure 2 As shown, the lower connecting plate 2 is located inside the seat cushion frame 1, as... Figure 3 and Figure 6 As shown, one end of the positioning flange is connected to the seat frame 1, and the other end of the positioning flange is bent and extended inward so that the positioning flange extends in the direction of the positioning groove, so that the positioning flange can be smoothly inserted into the positioning groove to cooperate with the inner wall of the positioning groove.

[0046] When the lower connecting plate 2 is located on the outside of the seat frame 1, the other end of the positioning flange can be bent and extended outward so that the positioning flange extends towards the positioning groove, so that the positioning flange can smoothly extend into the positioning groove to cooperate with the inner wall of the positioning groove.

[0047] In actual design, the positioning flange can be integrally formed with the seat cushion frame 1, that is, the positioning flange can be integrated with the seat cushion frame 1 as one piece, which is convenient to manufacture, makes the connection strength between the positioning flange and the seat cushion frame 1 higher, improves the connection stability and reliability between the positioning flange and the seat cushion frame 1, and prevents the positioning flange and the seat cushion frame 1 from breaking or separating, which would lead to pre-positioning failure.

[0048] In some embodiments, the positioning groove is provided on the lower side edge of the lower connecting plate 2 and is open downwards.

[0049] Specifically, such as Figure 3 As shown, the positioning groove is set on the lower edge of the lower connecting plate 2 and is open downwards. In this way, during actual assembly, the lower connecting plate 2 can be moved downwards so that the positioning flange extends into the positioning groove from the open side of the positioning groove and presses against the inner wall of the positioning groove to achieve a limiting fit. Thus, the lower connecting plate 2 and the seat frame 1 can be quickly and flexibly pre-positioned.

[0050] In practical design, such as Figure 2 and Figure 3 As shown, since the lower edge of the lower connecting plate 2 slopes from bottom to top, the positioning groove is set to be inclined and open to adapt to the structural shape of the lower connecting plate 2, which is conducive to quick pre-positioning.

[0051] In some embodiments, the positioning flange includes a first positioning segment and a second positioning segment that are bent and connected together. The first positioning segment passes through the positioning groove, and the second positioning segment extends to the side of the lower connecting plate 2 away from the seat frame 1.

[0052] Specifically, one end of the first positioning segment can be connected to the seat cushion frame 1, and the other end of the first positioning segment can be connected to one end of the second positioning segment. The other end of the second positioning segment is bent relative to the first positioning segment. The first positioning segment and the second positioning segment can be bent and connected at a 90-degree angle. For example, the first positioning segment can extend horizontally, and the second positioning segment can extend vertically. In this way, during actual assembly, the first positioning segment can be inserted into the positioning groove, and the second positioning segment can extend to the side of the lower connecting plate 2 away from the seat cushion frame 1 so as to be directly opposite the side of the lower connecting plate 2 away from the seat cushion frame 1. Thus, the first positioning segment can restrict the lower connecting plate 2 from moving downward, forward, and backward, and the second positioning segment can restrict the lower connecting plate 2 from moving to the side of the connecting plate away from the seat cushion frame 1, thereby achieving a more precise pre-positioning between the lower connecting plate 2 and the seat cushion frame 1.

[0053] In some embodiments, the seat frame 1 is further provided with a weakening opening 12, and a positioning flange is bent and connected to the edge of the weakening opening 12.

[0054] Specifically, a localized area of ​​the seat cushion frame 1 can be stamped to separate the material and bend it relative to the seat cushion frame 1, thereby forming a weakening opening 12 and a positioning flange. Since the weakening opening 12 is small in size, it will not affect the structural strength of the seat cushion frame 1. The positioning flange is bent and connected to the edge of the weakening opening 12. This improves the structural strength of the positioning flange, reduces the local stress at the connection between the positioning flange and the weakening opening 12, prevents the positioning flange from breaking, and ensures that the positioning flange extends smoothly towards the positioning groove to cooperate with the positioning groove.

[0055] Thus, while ensuring the overall structural strength of the seat cushion frame 1, the manufacturing of the positioning flange was achieved without increasing the weight of the seat cushion frame 1, making it flexible and convenient.

[0056] like Figure 3 and Figure 6 As shown, the seat frame 1 is provided with a weakening opening 12. The weakening opening 12 is constructed as a rectangular opening to form a rectangular positioning flange. Of course, the weakening opening 12 can also be set to other shapes to form positioning flanges of other shapes. It is flexible and selectable. The positioning flange is bent and connected to the lower edge of the weakening opening 12.

[0057] In some embodiments, such as Figure 3 As shown, the positioning groove has an opening side 211, and the opening width of the opening side 211 is set to gradually increase towards the outside of the positioning groove, that is, the width of the positioning groove gradually increases from the inside to the outside.

[0058] Therefore, the wider opening at the outermost end of the positioning groove reduces the initial positioning difficulty of the positioning flange when it is inserted into the positioning groove. This allows the positioning flange to be quickly inserted into the positioning groove without needing to be strictly aligned, reducing adjustment time and improving assembly efficiency. Furthermore, the variation in the width of the positioning groove can absorb a certain positional deviation, reducing assembly resistance and allowing the positioning flange to be easily inserted into the positioning groove. As the positioning flange is inserted into the positioning groove, the width of the positioning groove gradually decreases, which can automatically guide the positioning flange to the correct mating position, further reducing adjustment time.

[0059] In some embodiments, there are at least two first connectors 4, and the positioning part 11 and the positioning mating part 21 are located between two of the first connectors 4.

[0060] In other words, the first connector 4 can be set to two, three, four or more. By setting multiple first connectors 4, the lower connecting plate 2 and the seat cushion frame 1 can be connected at multiple positions through multiple first connectors 4, which can enhance the connection stability and reliability between the lower connecting plate 2 and the seat cushion frame 1, prevent the connection between the lower connecting plate 2 and the seat cushion frame 1 from loosening, and when one of the first connectors 4 fails, the other first connectors 4 can still work normally to ensure a stable and reliable connection between the lower connecting plate 2 and the seat cushion frame 1, and prevent the lower connecting plate 2 and the seat cushion frame 1 from separating.

[0061] The positioning part 11 and the positioning mating part 21 are located between the two first connecting parts 4 to avoid interference between the positioning part 11 and the positioning mating part 21 and the first connecting parts 4, and to ensure that the first connecting parts 4 are all close to the positioning part 11 and the positioning mating part 21, thereby ensuring that the first connecting parts 4 can be accurately installed.

[0062] In a specific embodiment, such as Figure 2 As shown, two first connectors 4 are provided. One first connector 4 is connected to the front of the lower connecting plate 2, and the other first connector 4 is connected to the rear of the lower connecting plate 2, thereby ensuring a stable connection between the lower connecting plate 2 and the seat frame 1 and preventing the lower connecting plate 2 from shifting or shaking to one side. The positioning part 11 and the positioning mating part 21 are located between the two first connectors 4, so that both first connectors 4 are close to the positioning part 11 and the positioning mating part 21, thereby ensuring that both first connectors 4 can be accurately installed.

[0063] In some embodiments, the seat frame 1 is provided with a first connecting hole 13, the lower connecting plate 2 is provided with a second connecting hole 22, and the first connecting member 4 is sequentially inserted through the first connecting hole 13 and the second connecting hole 22, thereby realizing a fixed connection between the lower connecting plate 2 and the seat frame 1.

[0064] Specifically, such as Figure 4 and Figure 5 As shown, when the first connecting member 4 is constructed as a bolt, the second connecting hole 22 can be constructed as a threaded through hole or a threaded flanged hole, that is, the second connecting hole 22 has internal threads. The first connecting hole 13 can be constructed as a through hole, and the positions of the first connecting hole 13 and the second connecting hole 22 correspond, so that the first connecting member 4 can be sequentially inserted into the first connecting hole 13 and the second connecting hole 22 to realize the bolted connection between the seat frame 1 and the lower connecting plate 2. Alternatively, a welding nut can be welded into the inside of the seat frame 1, so that the second connecting hole 22 is constructed as the threaded inner hole of the welding nut.

[0065] In actual assembly, the positioning part 11 and the positioning mating part 21 can be positioned and mated together, so that the first connecting hole 13 and the second connecting hole 22 can be quickly aligned. This allows the first connecting piece 4 to be quickly inserted into the first connecting hole 13 and the second connecting hole 22, so that the seat frame 1 and the lower connecting plate 2 can be quickly connected together without manual adjustment of the alignment of the first connecting hole 13 and the second connecting hole 22, thus improving the assembly accuracy and assembly efficiency of the first connecting piece 4.

[0066] This utility model also proposes a vehicle.

[0067] The vehicle according to the present invention includes the seat frame assembly 100 of any of the above embodiments.

[0068] In this design, a positioning part 11 is provided on the seat cushion frame 1, and a positioning mating part 21 is provided on the lower connecting plate 2. Through the positioning mating of the positioning part 11 and the positioning mating part 21, the pre-positioning between the seat cushion frame 1 and the lower connecting plate 2 is achieved. After that, the seat cushion frame 1 and the lower connecting plate 2 can be quickly and accurately detachably connected through the first connecting member 4, thereby improving assembly efficiency and assembly accuracy. Moreover, the positioning part 11 and the positioning mating part 21 have a simple structure, occupy little space, and will not affect the installation of the first connecting member 4. They are easy to manufacture, have low manufacturing costs, and high universality, which is conducive to achieving modularization and platformization, reducing the development cost of the entire seat frame assembly 100, and has a wide range of applications.

[0069] According to the present invention, by setting the above-mentioned seat frame assembly 100, the cost of the vehicle can be reduced and the manufacturing efficiency of the vehicle can be improved.
