Description

Technical Field

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

[0002] As a major component of the passenger compartment, the second-row seats require comfort and safety, as well as the ability to fold down the seatbacks to maximize luggage space. This means the second-row seatbacks must be able to rotate around the seat's pivot point. Therefore, the pivot point for the second-row seats must be both strong and allow the seatbacks to fold down, thus increasing luggage compartment volume.

[0003] Traditional seat hinge mounting brackets are typically welded to the rear wheel arch of the vehicle. The strength of the mounting bracket is increased by reinforcing the welded area on the rear wheel arch and by increasing the thickness of the mounting bracket itself. This type of component is relatively thick, easily resulting in four-layer welding or exceeding the reasonable thickness for spot welding, leading to poor welds. It also increases the weight of the structure and complicates the design of welding fixtures.

[0004] To address these issues, the mounting bracket is typically split into two parts, each directly welded to the rear wheel arch. The rear wheel arch is usually no more than 0.7mm thick, which is insufficient to withstand impact during seat safety testing. Therefore, a reinforcement is added to the side of the rear wheel arch away from the mounting bracket to strengthen its structure. However, the welding fixture design for this structure, which includes two brackets and a reinforcement, is complex and results in a heavy structure. Utility Model Content

Detailed Implementation

[0029] To enable those skilled in the art to better understand the technical solutions of this application, the technical solutions in some embodiments of this application will be clearly and completely described below with reference to the accompanying drawings.

[0030] It should be noted that the terms "first," "second," etc., used in the specification, claims, and accompanying drawings of this application are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that such terms can be used interchangeably where appropriate so that the embodiments of this application described herein can be implemented in orders other than those illustrated or described herein. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this application. Rather, they are merely examples of apparatuses and methods consistent with some aspects of this application as detailed in the appended claims.

[0031] To address the problems existing in common mounting bracket structures, some embodiments of this application provide a seat hinge mounting device. This seat hinge mounting device has fewer parts, lighter structure, and simpler welding layers, while improving the installation rigidity and strength of the second-row seats. The seat hinge mounting device is suitable for vehicles, such as sedans, SUVs, new energy vehicles, and traditional fuel vehicles.

[0032] Figures 1 to 6 The present application illustrates a seat pivot mounting device and a seat assembly including the seat pivot mounting device, according to some embodiments of the present application.

[0033] In some embodiments, such as Figures 1 to 5 As shown, the seat pivot mounting device 120 includes a mounting bracket 121 and a seat pivot 122. The mounting bracket 121 is configured to be mounted to the rear wheel arch assembly 200 and the rear floor assembly 300 of the vehicle, and the seat pivot 122 is fixedly connected to the mounting bracket 121.

[0034] In some embodiments, the mounting bracket 121 and the seat pivot 122 may be fixedly connected by welding, and this application does not limit this.

[0035] In some embodiments, the mounting bracket 121 may be made of cold-rolled low-carbon steel. For example, the mounting bracket 121 may be made of DC series steel (e.g., DC01, DC03, or DC04). In some embodiments, the thickness of the mounting bracket 121 may be in the range of [1.0 mm, 1.4 mm]. For example, the thickness of the mounting bracket 121 may be 1.0 mm, 1.1 mm, 1.2 mm, 1.3 mm, or 1.4 mm. In some embodiments, the model number of the mounting bracket 121 may be DC01-1.2 mm.

[0036] In this way, the weight of the mounting bracket 121 can be reduced while ensuring its installation rigidity and strength.

[0037] In some embodiments, the seat pivot 122 may be a 45# steel part or other parts that can ensure its installation rigidity and strength. In some embodiments, the diameter of the seat pivot 122 is in the range of [10mm, 14mm]. For example, the diameter of the seat pivot 122 may be 10mm, 11mm, 12mm, 13mm or 14mm.

[0038] This reduces the weight of the seat pivot 122 while ensuring its installation rigidity and strength.

[0039] In some embodiments, the mounting bracket 121 is provided with at least two mounting holes 1211. The at least two mounting holes 1211 include at least one first mounting hole 1211A and at least one second mounting hole 1211B.

[0040] In some embodiments, the seat pivot mounting device 120 further includes at least two fasteners 123, each corresponding to at least two mounting holes 1211. The at least two fasteners 123 include at least one first fastener 123A and at least one second fastener 123B. The at least one first fastener 123A corresponds to the at least one first mounting hole 1211A, and the at least one second fastener 123B corresponds to the at least one second mounting hole 1211B. The mounting bracket 121 is configured to be mounted to the rear wheel arch assembly 200 via the at least one first fastener 123A and the at least one first mounting hole 1211A, and to be mounted to the rear floor assembly 300 via the at least one second fastener 123B and the at least one second mounting hole 1211B.

[0041] In some embodiments, fastener 123 is a screw thread. For example, mounting bracket 121 is configured to be screwed to rear wheel arch assembly 200 via a screw thread. For example, mounting bracket 121 is configured to be screwed to rear floor assembly 300 via a screw thread.

[0042] In some embodiments, the at least one first mounting hole 1211A includes two first mounting holes 1211A, and the at least one second mounting hole 1211B includes two second mounting holes 1211B.

[0043] In some embodiments, the at least one first fastener 123A includes two first fasteners 123A, and the at least one second fastener 123B includes two second fasteners 123B. For example... Figure 1 and Figure 2As shown, the seat pivot mounting device 120 includes four fasteners 123, which are respectively disposed in relation to four mounting holes 1211. The mounting bracket 121 is screwed to the rear wheel arch assembly 200 via two first fasteners 123A and two first mounting holes 1211A, and is screwed to the rear floor assembly 300 via two second fasteners 123B and two second mounting holes 1211B.

[0044] This design avoids damage caused by insufficient structural strength of the rear wheel arch assembly, which could result from connecting the mounting bracket only to the rear wheel arch assembly. Furthermore, it increases the mounting range of the seat pivot within the mounting bracket. Understandably, the seat primarily bears the impact force from the vehicle's forward direction during a collision, and the four fasteners provide sufficient tangential force to ensure the seat's mounting strength.

[0045] In some embodiments, such as Figure 2 and Figure 3 As shown, any one of the at least two fasteners 123 includes a first screw connector 1231 and a second screw connector 1232. The first screw connector 1231 and the second screw connector 1232 cooperate to achieve screwing of the mounting bracket 121 to the rear wheel arch assembly 200 and the rear floor assembly 300.

[0046] In some embodiments, the first bolt 1231 can be an M8 hexagonal flange bolt, that is, the mounting bracket 121 is mounted on the vehicle body by four M8 hexagonal flange bolts, two of which are connected to the rear wheel arch assembly 200 and the other two are connected to the rear floor assembly 300.

[0047] In some embodiments, the second screw connector 1232 is a nut that mates with the first screw connector 1231.

[0048] In some embodiments, such as Figure 3 As shown, the rear wheel arch assembly 200 and the rear floor assembly 300 have overlapping surfaces on their adjacent sides. The at least one second mounting hole 1211B includes a second mounting hole (mounting point) a and a second mounting hole (mounting point) b. The overlapping surface is provided with two mounting holes corresponding to the second mounting hole a and the second mounting hole b, respectively aligned with the two mounting holes on the overlapping surface.

[0049] This configuration saves interior space, improves seat comfort, and eliminates the need for mounting point structures on the rear floor assembly 300, simplifying the installation design of the mounting bracket 121.

[0050] In some embodiments, at least one of the at least two fasteners 123 is a waterproof welding fastener.

[0051] Understandably, the design of the mounting holes and fasteners would cause the interior of the vehicle to communicate with the exterior through the second mounting holes a and b. That is, the first screw 1231 needs to directly penetrate the overlapping surface formed by the rear wheel arch assembly 200 and the rear floor assembly 300 on their adjacent sides. This may result in poor sealing of the entire vehicle, and liquids from outside the vehicle may enter the vehicle through the second mounting holes a and b, causing damage to the internal components of the vehicle.

[0052] Therefore, in some embodiments, at least one second fastener 123B screwed to the rear floor assembly 300 has a waterproof function. For example, the second screw 1232 screwed to the rear floor assembly 300 is an M8 waterproof welded round nut. This ensures the overall sealing of the vehicle and prevents damage to internal components from ingress of liquid.

[0053] In some embodiments, such as Figure 4 As shown, the area of ​​the mounting bracket 121 for mounting the seat pivot 122 ranges from [7500mm]. 2 7700mm 2 For example, the area of ​​the mounting bracket 121 for mounting the seat pivot 122 is 7500 mm². 2 7550mm 2 7600mm 2 7626mm 2 7700mm 2 .

[0054] In some embodiments, the area of ​​the mounting bracket 121 for mounting the seat pivot 122 is 7626 mm². 2 That is, the area of ​​the wide bandwidth arrangement of the seat pivot 122 in the mounting bracket 121 can reach 7626 mm². 2 .

[0055] In actual operation, the position of the seat pivot 122 in the mounting bracket 121 can be adjusted according to the needs of the vehicle. After adjustment, the seat pivot 122 and the mounting bracket 121 are fixedly connected to achieve universal arrangement of different models and different seats under the condition of consistent vehicle body structure, reducing the difficulty of vehicle body design and reducing vehicle body weight.

[0056] It is understandable that the area of ​​the mounting bracket 121 for mounting the seat pivot 122 is 7626 mm². 2 In this case, when adjusting the position of the seat pivot 122 in the mounting bracket 121, there is a wide range of positions that can be selected, making it easy to adapt to the installation needs of different models and different seats.

[0057] like Figure 5 and Figure 6As shown, some embodiments of this application provide a seat assembly 100, which includes a seat 110 and a seat pivot mounting device 120 as described in any of the above embodiments.

[0058] The seat 110 has a backrest hole 111. When assembling the vehicle's seat assembly 100, the backrest hole 111 is directly inserted into the seat shaft 122 of the seat shaft mounting device 120 to achieve the cooperation between the seat 110 and the seat shaft mounting device 120. Then, through the cooperation between the mounting bracket 121 and the seat shaft 122, the installation of the seat assembly 100 and the rotation function of its backrest around the shaft can be realized. The installation method is simple and quick.

[0059] Figure 7 This is a schematic diagram illustrating seat crash test analysis of some embodiments of this application. In some embodiments, such as Figure 7 As shown, in the seat collision test on the vehicle using the above design, the pivot mounting point of the second-row seats did not undergo significant deformation upon impact. That is, by using the seat pivot mounting device 120 in some embodiments of this application, the structural strength of the pivot mounting point of the second-row seats can be guaranteed.

[0060] like Figure 8 As shown, some embodiments of this application provide a vehicle 1000, which includes a seat assembly 100, a rear wheel arch assembly 200, and a rear floor assembly 300.

[0061] The seat assembly 100 includes a seat 110 and a seat pivot mounting device 120 as shown in any of the above embodiments. The mounting bracket 121 of the seat pivot mounting device 120 is configured to mount the seat 110 to the rear wheel arch assembly 200 and the rear floor assembly 300 of the vehicle. The seat pivot 122 of the seat pivot mounting device 120 is fixedly connected to the mounting bracket 121, and the seat 110 is rotatable relative to the seat pivot 122.

[0062] In some embodiments, the rear floor assembly 300 and the rear wheel arch assembly 200 have an overlapping area, the mounting bracket 121 is mounted to the mounting point of the rear floor assembly 300 and the rear wheel arch assembly 200 located in the overlapping area, and the seat 110 has a backrest hole 111, into which the seat pivot 122 is inserted.

[0063] In some embodiments, the seat pivot mounting device 120 further includes at least two fasteners 123 that pass through the rear floor assembly 300 and the rear wheel arch assembly 200, and at least two fasteners 123 are sealed.

[0064] By employing the seat pivot mounting device, seat assembly, and vehicle described in some embodiments of this application, the vehicle body structure design is simplified, and the number of parts is greatly reduced. Compared with traditional designs, the vehicle body welding layers are simpler, which is conducive to tooling structure design and production line layout, effectively improving production efficiency. Furthermore, the seat mounting points have high strength and extremely high adaptability to layout bandwidth, satisfying the installation and arrangement of different seats within the same vehicle model.

[0065] The above are merely specific embodiments of this application, but the scope of protection of this application is not limited thereto. Any changes or substitutions within the technical scope disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
