Description

Technical Field

[0001] This utility model relates to the field of vehicle technology, and in particular to a seat assembly and a vehicle. Background Technology

[0002] In traditional technology, the seat frame is made of high-strength steel, and the airbag assembly and support assembly are bolted to the seat frame. This type of seat structure has a relatively large mass. With the trend of lightweighting in automobiles, one-piece carbon fiber seat back panels made of carbon fiber materials are gradually replacing traditional metal seat frames as the core load-bearing structure of vehicle seats due to their excellent properties such as high specific strength, low density, and fatigue resistance.

[0003] However, the significant differences in material properties between carbon fiber and metal make it difficult to install airbag and support components onto the carbon fiber backplate. For example, carbon fiber does not have a high-temperature melting range, so the welding process used for metal frames cannot be used; in addition, opening holes in the carbon fiber backplate will cause stress concentration and deteriorate the overall mechanical properties, so the bolt connection process used for metal frames cannot be directly used.

[0004] In related technologies, the connection of various components on the back panel is achieved by bonding. The airbag assembly and the support assembly need to be bonded to the carbon fiber back panel separately, which is a complicated installation process and has low installation efficiency.

In this specification, the illustrative expressions of the above terms do not necessarily refer to the same embodiment or example. Furthermore, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples.

[0045] In related technologies, the connection of various components on the back panel is achieved by bonding. The airbag assembly and the support assembly need to be bonded to the carbon fiber back panel separately, which is a complicated installation process and has low installation efficiency.

[0046] To address the aforementioned problems, this application proposes a seat assembly, such as... Figure 1 and Figure 2As shown, the seat assembly includes a backrest assembly 200, a mounting bracket 100, a support assembly 300, and an airbag assembly 400. The support assembly 300 can be a side wing support, providing counter-support force to the occupant's lumbar region during high-speed cornering or emergency lane changes, thereby limiting lateral displacement of the occupant's body and stabilizing the seating posture. The support assembly 300 can also be a lumbar support, ergonomically designed to conform the seat back to the occupant's lumbar spine, reducing muscle fatigue caused by long-term driving. The support assembly 300 can also be other types of support, such as shoulder support or leg support. The type of support assembly 300 needs to be designed according to the specific structural layout of the seat assembly. The airbag assembly 400 can protect the occupant in the event of a collision. The seat assembly of this application is equipped with an airbag assembly 400, which can be a side chest airbag, a pelvic airbag, a head airbag, etc. In this embodiment, the support component 300 is a side wing support, and the airbag component 400 is a side curtain airbag, both of which are mounted on the seat assembly and located on the side of the back panel component 200.

[0047] In this application, both the support assembly 300 and the airbag assembly 400 are connected to the mounting bracket 100, and are uniformly connected to the backplate assembly 200 via the mounting bracket 100. Specifically, as shown... Figure 3 and Figure 4 As shown, the mounting bracket 100 includes a first connecting portion 110 and a first main body portion 120 connected to the first connecting portion 110. The first main body portion 120 is used to connect to the support assembly 300 and the airbag assembly 400 respectively, and the first connecting portion 110 is used to connect to the backplate assembly 200. Figure 2 As shown, the backplate assembly 200 includes a backplate body 210 and an adapter bracket 220 connected to the backplate body 210. The backplate body 210 can be made of carbon fiber composite material, which has good specific strength, good fatigue resistance and corrosion resistance, and is lightweight, which can effectively reduce vehicle weight.

[0048] If the backplate body 210 adopts a one-piece carbon fiber structure, the adapter bracket 220 and the backplate body 210 can be connected by adhesive bonding. It is understandable that carbon fiber composite materials are anisotropic materials, and their laminated structure is very sensitive to machining processes such as drilling and cutting. Mechanical connections (such as bolts and rivets) require drilling holes in the material, leading to stress concentration around the holes, which may cause interlayer delamination or localized strength reduction. Adhesive bonding, on the other hand, transfers load through the adhesive layer without disrupting fiber continuity, thus better utilizing the axial tensile strength of carbon fiber.

[0049] like Figure 2 and Figure 9As shown, the adapter bracket 220 is provided with a second connecting part 221. The adapter bracket 220 can be made of metal. Therefore, the second connecting part 221 can be a bolt hole for bolt connection, a snap-fit ​​structure for snap-fit, or a welding point for welding, etc. Due to the characteristics of metal materials, the provision of the second connecting part 221 will not have a significant impact on the strength of the adapter bracket 220. By providing the adapter bracket 220, the backplate assembly 200 can be mechanically connected to the mounting bracket 100.

[0050] During the assembly of the seat assembly, firstly, the adapter bracket 220 is fixed to the backrest assembly 200; secondly, the support assembly 300 and the airbag assembly 400 are respectively connected to the mounting bracket 100. Then, through the connection and cooperation of the first connecting part 110 and the second connecting part 221, the mounting bracket 100 is connected to the adapter bracket 220, thereby installing the support assembly 300 and the airbag assembly 400 onto the backrest body 210 in one go. In this embodiment, the assembly processes of the first and second aspects can be performed simultaneously, thereby shortening the waiting time of each step in the assembly process and significantly reducing the production cycle.

[0051] Based on the above, the seat assembly of this embodiment can adopt a carbon fiber structure, achieving both lightweighting and good structural strength. By connecting the adapter bracket 220 to the backrest body 210, mechanical connection with the airbag assembly 400 and support assembly 300 can be achieved without damaging the mechanical structure of the backrest body 210. By uniformly connecting the airbag assembly 400 and support assembly 300 to the mounting bracket 100 before assembling them onto the backrest body 210, it is not necessary to connect the airbag assembly 400 and support assembly 300 separately to the backrest assembly 200, greatly improving assembly efficiency. Furthermore, the airbag assembly 400 and support assembly 300 are mechanically connected to the mounting bracket 100, which on the one hand reduces the difficulty of the assembly process and increases the assembly speed; on the other hand, it facilitates the individual disassembly and assembly of the airbag assembly 400 and support assembly 300, which is beneficial for modular replacement of various components on the seat assembly.

[0052] In some embodiments, such as Figure 4 As shown, the first main body 120 and the first connecting part 110 are connected by a bending section 130, so that the first main body 120 and the first connecting part 110 are in different planes. When the first connecting part 110 of the mounting bracket 100 is fitted and connected to the second connecting part 221 of the adapter bracket 220, refer to Figure 1As shown, the first main body portion 120 and the back panel assembly 200 are spaced apart, and an accommodating gap (not shown) is defined between the first main body portion 120 and the back panel assembly 200. The support assembly 300 and the airbag assembly 400 are respectively connected to both sides of the first main body portion 120. Furthermore, the support assembly 300 is connected to the side of the first main body portion 120 away from the back panel assembly 200, and the airbag assembly 400 is connected to the side of the first main body portion 120 facing the back panel assembly 200, so that the airbag assembly 400 is at least partially located in the accommodating gap.

[0053] The airbag assembly 400 includes an airbag that can rapidly inflate and deploy to cushion the impact on the occupant. The clearance between the mounting bracket 100 and the backplate assembly 200 guides the airbag's inflation, ensuring it deploys along a predetermined path, improving the accuracy of the airbag's deployment position, and reducing the risk of injury to the occupant during a collision.

[0054] In some embodiments, such as Figure 3 As shown, the mounting bracket 100 also includes a first limiting part 121 and a third connecting part 122. The first limiting part 121 is connected to the first main body part 120, and the third connecting part 122 is disposed on the first main body part 120. Figures 5 to 7 As shown, the support assembly 300 includes a second limiting part 310 and a fourth connecting part 320, which are located on both sides of the support assembly 300 along its width direction. The first limiting part 121 and the second limiting part 310 abut against each other, and the third connecting part 122 and the fourth connecting part 320 are fixedly connected. During the installation of the support assembly 300, the second limiting part 310 is first abutted against the first limiting part 121 to initially limit the displacement of the support assembly 300. At this time, the third connecting part 122 and the fourth connecting part 320 are in a suitable position for connection. Then, the support assembly 300 and the mounting bracket 100 are fixed by the third connecting part 122 and the fourth connecting part 320.

[0055] Furthermore, such as Figure 7 As shown, the first limiting part 121 is a rod, and the second limiting part 310 is provided with a groove. The rod and the groove are engaged through a plug-in connection to achieve pre-fixation and pre-positioning during the installation of the support assembly 300. Figure 3As shown, when viewed along the thickness direction of the first main body 120, at least a portion of the rod used for inserting into the groove is located outside the first main body 120. It should be explained that in some embodiments, the support assembly 300 can also be pre-fixed by providing an abutment protrusion on the first main body 120, with the abutment protrusion located on the first main body 120. In this embodiment, both ends of the rod are connected to the first main body 120, and its middle portion extends beyond the first main body 120, serving to support and limit the support assembly 300. This reduces the area requirement of the first main body 120, saves space, and facilitates further thinning of the seat assembly.

[0056] In addition, the third connecting part 122 is provided with a first connecting hole 1222, and the fourth connecting part 320 is provided with a second connecting hole 321. When the rod is inserted into the groove, the first connecting hole 1222 and the second connecting hole 321 are connected. The seat assembly also includes fasteners such as bolts. The fasteners can pass through the first connecting hole 1222 and the second connecting hole 321 to realize the connection and fixation of the support component 300 and the mounting bracket 100.

[0057] Furthermore, such as Figure 3 As shown, the third connecting portion 122 also includes a first boss 1221 for abutting against the fourth connecting portion 320. The first boss 1221 protrudes from the first main body portion 120, and a first connecting hole 1222 is provided on the first boss 1221. The mounting bracket 100 abuts against the support assembly 300 through the first boss 1221, thus having a smaller abutment area. It is understood that a large contact area requires a high degree of flatness between the two contact surfaces. If the precision is not met, it may cause vibration and abnormal noise, affecting the passenger's riding experience. Therefore, the abutment area between the mounting bracket 100 and the support assembly 300 is reduced by the first boss 1221, thereby reducing the precision requirements of the processing and effectively controlling vibration and abnormal noise. Similarly, the fourth connecting portion 320 may also be provided with a second boss (not shown in the figure) for abutting against the third connecting portion 122, and a second connecting hole 321 is provided on the second boss.

[0058] Correspondingly, the edge of the first main body 120 of the mounting bracket 100 is also provided with a flange for abutting against the support component 300, thereby supporting the support component 300 and reducing the risk of vibration and abnormal noise.

[0059] In some embodiments, the support assembly 300 includes a first housing 330, a second housing 340, and a drive member, such as... Figure 6As shown, the first housing 330 is connected to the mounting bracket 100, and the first housing 330 is provided with a second limiting part 310 and a fourth connecting part 320. The second housing 340 is rotatably connected to the first housing 330, and a receiving cavity is defined between the second housing 340 and the first housing 330, with a driving component disposed in the receiving cavity. The driving component is generally an air bag, which can be controlled to expand or contract, thereby driving the second housing 340 to rotate relative to the first housing 330. For example, when the air bag expands, the second housing 340 opens relative to the first housing 330, and the support assembly 300 provides enhanced support for the occupant; when the air bag contracts, the second housing 340 closes relative to the first housing 330, and the support assembly 300 provides reduced support for the occupant. It can be understood that the expansion or contraction of the air bag can be actively controlled by the occupant or automatically adjusted according to the vehicle body posture.

[0060] In other embodiments, the drive unit may also be a hydraulic pump, an air pump, or a motor, etc. The drive unit is connected in communication with the vehicle computer and is controlled to drive the second housing 340 to rotate relative to the first housing 330.

[0061] In some embodiments, such as Figure 2 and Figure 8 As shown, the airbag assembly 400 also includes an airbag body 410 and a fifth connecting portion 420 connected to the airbag body 410. The airbag body 410 houses an airbag and an airbag triggering mechanism. The first main body 120 is provided with a sixth connecting portion 123. The fifth connecting portion 420 is used to connect to the sixth connecting portion 123 of the mounting bracket 100. The fifth connecting portion 420 can be as follows: Figure 8 The bolt shown, or a snap-fit ​​structure that mates with the sixth connecting part 123, can be used to connect the fifth connecting part 420 and the sixth connecting part 123 so that the airbag body 410 can be fixed on the mounting bracket 100.

[0062] To prevent the airbag body 410 from moving or rotating relative to the mounting bracket 100 during installation, the airbag assembly 400 also includes a third limiting part 430 disposed on the outer peripheral surface of the airbag body 410, and a fourth limiting part 124 is correspondingly disposed on the first main body part 120 of the mounting bracket 100. When the third limiting part 430 and the fourth limiting part 124 abut, the fifth connecting part 420 and the sixth connecting part 123 are in a position suitable for connection.

[0063] Specifically, either the third limiting part 430 or the fourth limiting part 124 can be a groove or a through groove, and the other is a protrusion, the shape of which corresponds to the groove or through groove. Furthermore, the groove or through groove is not necessarily circular; it can be a square groove, a triangular groove, an elliptical groove, etc. For example, if the mounting bracket 100 has a square groove and the outer circumferential surface of the airbag body 410 has a square protrusion, during installation, the square protrusion of the airbag body 410 is first aligned with the square groove on the mounting bracket 100 and inserted. At least one wall of the square protrusion abuts against the corresponding wall of the directional groove, thus achieving pre-positioning and pre-fixation of the airbag body 410's installation position. Since the protrusion and groove are square, the rotational freedom of the airbag body 410 is also restricted. At this time, the bolt of the fifth connecting part 420 passes through the bolt hole of the sixth connecting part 123 for easy tightening by the operator.

[0064] As shown in the figure, the outer surface of the airbag body 410 is provided with two fifth connecting portions 420 and a third limiting portion 430, with the third limiting portion 430 located between the two fifth connecting portions 420. Furthermore, the first main body 120 is provided with two sixth connecting portions 123, both of which are bolt holes penetrating the first main body 120. One bolt hole is round, and the other is elliptical. The elliptical bolt hole allows for certain machining and assembly errors, facilitating the connection between the mounting bracket 100 and the airbag assembly 400.

[0065] In some embodiments, the adapter bracket 220 is bonded to the backrest body 210, and the seat assembly also includes an adjustment assembly 500, such as... Figure 1 and Figure 2 As shown, the adjustment component 500 is used to adjust the angle of the seat back panel relative to the seat cushion to meet the seating needs of different occupants. In addition to the second connecting part 221 that connects to the mounting bracket 100, the adapter bracket 220 also has a seventh connecting part 222 that connects to the adjustment component 500 (e.g., ...). Figure 9 As shown), this allows for the installation of multiple functional components on the backplate body 210 via an adapter bracket 220. Figure 2 As shown, the adjustment assembly 500 includes a connecting bracket 510 and an adjustment mechanism 520, and the adjustment mechanism 520 is connected to the adapter bracket 220 through the connecting bracket 510.

[0066] like Figure 1 , Figure 2 and Figure 9As shown, it should be explained that, since the support component 300 and the airbag component 400 in the embodiments of this application are both located on the side of the back panel body 210, while the adjustment component 500 of this application is located at the bottom of the back panel body 210, the adapter bracket 220 is located on the lower side of the back panel body 210 and is in a bent shape to fit the back panel body 210.

[0067] The second aspect of this application also proposes a vehicle that includes the seat assembly mentioned in any of the foregoing embodiments. The vehicle can be a private car, such as a sedan, SUV, MPV, or pickup truck. It can also be a commercial vehicle, such as a van, bus, small truck, or large trailer. The vehicle can be a gasoline-powered vehicle or a new energy vehicle. When the vehicle is a new energy vehicle, it can be a hybrid vehicle or a pure electric vehicle. Since the vehicle in this aspect embodiment includes the seat assembly of the first aspect embodiment, it possesses the beneficial effects of the first aspect embodiment, which will not be repeated here.

[0068] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
