Description

Technical Field

[0001] The invention belongs to the field of automobiles, and in particular relates to a rear seat mounting bracket and an automobile which are beneficial to luggage compartment impact. Background Art

[0002] As cars become more and more complex on the road, consumers are paying more and more attention to car safety. Upgraded regulations are placing increasingly stringent requirements on car body structures. Therefore, designing high-standard automotive structural parts that meet safety requirements in various working conditions during the research and development stage is of paramount importance.

[0003] Currently, in trunk impact conditions, the seat mounting brackets connecting the car seat to the vehicle body typically use single-layer or "J"-shaped structures, which have low rigidity. If the car suddenly brakes while driving, the trunk impacts the seat back, causing the seat to tilt forward. However, due to the seat mounting bracket's insufficient rigidity, it is unable to withstand the impact of the trunk, resulting in a significant forward displacement of the seat and a high risk of injury to the vehicle occupants.

[0004] The seat mounting brackets are bolted to the vehicle floor, but due to insufficient rigidity, the impact force is transmitted to the vehicle floor via the left seat mounting bracket during an impact. This can cause excessive stress in the floor and risk tearing. Furthermore, the crossbeams of the seat mounting brackets are rarely connected, so the force is transmitted to the crossbeams via bolted connections during an impact, which can lead to stress concentration and significant damage. Long-term use can easily lead to damage, posing a risk to vehicle occupants. Summary of the Invention

[0005] The purpose of the present invention is to provide a seat bracket and a car with a stable structure, high rigidity and the ability to withstand the impact of a luggage box. The present invention improves the rigidity of the seat mounting bracket so that the seat can withstand the impact of the luggage box and ensure the safety of the passengers in the car.

[0006] In order to achieve the above object, the technical solution adopted by the present invention is as follows:

[0007] In the first aspect, the present invention provides a seat mounting bracket that is beneficial to the impact of the luggage box, including a connecting plate, a seat mounting beam assembly and a base bracket assembly. The seat mounting beam assembly is arranged on the base bracket assembly along the length direction of the vehicle. The seat mounting beam assembly includes an upper beam and a lower beam. The upper beam and the lower beam are both C-shaped steel structures. The two C-shaped steel structures are inserted together and welded to form a whole. The two C-shaped steel structures form a structure with a concave portion in the middle and raised portions at both ends. A seat mounting hole is provided on the raised portion, and a base mounting hole is provided on the concave portion; the base bracket assembly is connected to the seat mounting beam assembly through the base mounting hole and two connecting plates.

[0008] As a further technical solution, the areas of the two raised portions are not equal, two seat mounting holes are provided on the raised portion with a larger area, and one seat mounting hole is provided on the raised portion with a smaller area.

[0009] As a further technical solution, the base bracket assembly is a curved structure, which includes an upper base bracket and a lower base bracket. The lower base bracket is welded to the bottom of the upper base bracket 301.

[0010] As a further technical solution, the upper bracket of the base includes a vertical portion, a first horizontal portion and a second horizontal portion. The vertical portion and the first horizontal portion are smoothly transitioned through a circular arc, the first horizontal portion and the second horizontal portion are smoothly transitioned through a circular arc, and a step is formed between the second horizontal portion and the first horizontal portion.

[0011] As a further technical solution, the vertical portion is provided with a longitudinal beam mounting hole, and the base bracket assembly is connected to the longitudinal beam of the vehicle body through the longitudinal beam mounting hole.

[0012] As a further technical solution, a seat mounting crossbeam assembly is installed on the first horizontal portion.

[0013] As a further technical solution, a vehicle body mounting hole is provided on the second horizontal portion, and the base bracket assembly is connected to the vehicle body bottom plate through the vehicle body mounting hole.

[0014] As a further technical solution, the above-mentioned base lower bracket is welded to the entire bottom of the base upper bracket, and the base lower bracket and the base upper bracket both adopt sheet metal structure.

[0015] As a further technical solution, along the length direction of the upper bracket of the base, both sides of the upper bracket of the base are designed to be convex, which plays a certain reinforcing role.

[0016] In a second aspect, the present invention discloses a car seat, the bottom of which is provided with the aforementioned mounting bracket.

[0017] In a third aspect, the present invention further provides an automobile, wherein a seat is mounted on the seat mounting bracket, and one end of the base bracket assembly is connected to the automobile floor, and the other end is connected to the automobile longitudinal beam.

[0018] As a further technical solution, at least two of the seat mounting brackets are installed on the bottom of each seat, and the multiple seat mounting brackets are symmetrically arranged.

[0019] The working principle of the present invention is as follows:

[0020] When the seat is impacted by the trunk, the seat backrest tilts forward due to the impact force, thereby driving the seat mounting crossbeam assembly. Since the seat mounting bracket base adopts a double-layer sheet metal structure and is connected to the seat mounting crossbeam by a connecting plate, it can withstand a large impact force, making the forward displacement of the seat smaller, and providing more space for the passengers in the car, thereby ensuring the safety of the passengers.

[0021] The beneficial effects of the present invention are as follows:

[0022] The present invention designs the structure of the seat mounting beam assembly based on the stress strength of the seat, the material consumption of the bracket and the convenience of bracket installation, that is, the seat mounting beam assembly is formed by welding two C-shaped steel structures together. Compared with directly using a rectangular steel, its stress strength is better, and the top and bottom of the seat mounting beam assembly are subjected to relatively large stress. Through this design, the top and bottom thicknesses of the seat mounting beam assembly are twice as thick as the side surfaces, thereby meeting the stress requirements; further, the present invention designs the two ends of the seat mounting beam assembly into an asymmetric structure, so that when installing the seat mounting beam assembly, the raised part with a large area can be connected to the position of the seat with relatively large stress, and the raised part with a small area can be connected to the position of the seat with relatively small stress, thereby meeting the overall stress requirements; further, the middle of the seat mounting beam assembly is designed to be concave in order to save materials on the one hand and facilitate operation on the other hand. When installing the seat, the operating space reserved in the concave part can be used for operation.

[0023] The seat mounting crossbeam assembly and the base bracket assembly of the present invention are connected by welding two connecting plates, so the structure is more stable and the force is more balanced.

[0024] The lower base bracket of the present invention is welded to the entire bottom of the upper base bracket. Both the lower base bracket and the upper base bracket adopt sheet metal structure, that is, the base bracket assembly adopts a double-layer sheet metal structure, which has a large room for strength improvement and a significant effect of improving impact resistance.

DETAILED DESCRIPTION

[0030] It should be noted that the following detailed description is illustrative and is intended to provide further explanation of the present invention. Unless otherwise specified, all technical and scientific terms used in the present invention have the same meaning as commonly understood by those skilled in the art to which the present invention belongs.

[0031] It should be noted that the terms used herein are only for describing specific embodiments and are not intended to limit the exemplary embodiments according to the present invention. As used herein, unless otherwise clearly indicated in the present invention, the singular form is also intended to include the plural form. In addition, it should be understood that when the terms "include" and / or "comprising" are used in this specification, they indicate the presence of features, steps, operations, devices, components and / or their combinations;

[0032] Example 1

[0033] like Figure 1 As shown, the seat mounting bracket disclosed in this embodiment primarily comprises a connecting plate 1, a seat mounting crossbeam assembly 2, and a base bracket assembly 3. The seat mounting crossbeam assembly 2 is positioned on the base bracket assembly 3 along the length of the vehicle. The seat mounting crossbeam assembly 2 and the base bracket assembly 3 are connected by bolts through mounting holes 7 and welded together via two connecting plates 1, thereby securing their relative positions. When the seat is impacted by a luggage compartment, the seat backrest tilts forward due to the impact force, thereby driving the seat mounting crossbeam assembly 2. Because the seat mounting bracket assembly 3 utilizes a double-layer sheet metal structure and is connected to the seat mounting crossbeam assembly 2 via a connecting plate, it can withstand significant impact forces, minimizing the forward displacement of the seat, providing more space for vehicle occupants and ensuring their safety.

[0034] Furthermore, the above-mentioned seat mounting crossbeam assembly 2 includes an upper crossbeam 201 and a lower crossbeam 202, and the upper crossbeam 201 and the lower crossbeam 202 are connected by welding. Specifically, the upper crossbeam 201 is a C-shaped steel structure, and the lower crossbeam 202 is also a C-shaped steel structure. The two C-shaped steel structures are inserted together and welded to form a whole. The structure formed by the two C-shaped steel structures is a concave portion in the middle part and a convex portion at both ends. The convex portion is provided with a seat mounting hole 6, and the concave portion is provided with a base mounting hole 7; the specific insertion form is: the top and bottom of one C-shaped steel are pressed on the top and bottom of the other C-shaped steel, such as Figure 1As shown, the top of the whole is a two-layer steel plate, and the bottom is also a two-layer steel plate.

[0035] Furthermore, the seat mounting crossbeam assembly 2 is connected to the seat through the seat mounting holes 6 and bolts.

[0036] Furthermore, the two protrusions are asymmetrical structures, such as Figure 1 As shown, the area of ​​the left raised portion is larger than that of the right raised portion, two seat mounting holes 6 are provided on the left raised portion, and one seat mounting hole 6 is provided on the right raised portion;

[0037] The present invention designs the upper and lower crossbeams 201 and 202 into the aforementioned shapes, primarily based on factors such as strength, material availability, and ease of installation. Specifically, the seat mounting crossbeam assembly 2 is formed by welding two C-shaped steel structures together. This design provides superior strength compared to a single rectangular steel structure, and the top and bottom of the seat mounting crossbeam assembly 2 are subject to greater stress. This design allows the top and bottom thicknesses of the seat mounting crossbeam assembly 2 to be twice as thick as the side thicknesses, thereby meeting the required strength. Furthermore, the present invention designates the ends of the seat mounting crossbeam assembly 2 as asymmetrical structures, also because the seat is subjected to uneven stress during use. Therefore, when installing the seat mounting crossbeam assembly 2, the larger raised portion can be connected to the seat's location subject to greater stress, while the smaller raised portion can be connected to the seat's location subject to less stress. Furthermore, the recessed center of the seat mounting crossbeam assembly 2 is designed to save material and facilitate operation, allowing the seat to be installed using the space reserved in the recessed portion.

[0038] Furthermore, the base support assembly 3 is a curved structure, which includes a base upper support 301 and a base lower support 302. The base lower support 302 is welded to the bottom of the base upper support 301, wherein the base upper support 301 includes three parts, namely a vertical part, a first horizontal part and a second horizontal part. The vertical part and the first horizontal part are smoothly transitioned through an arc, and the first horizontal part and the second horizontal part are smoothly transitioned through an arc, and a step is formed between the second horizontal part and the first horizontal part.

[0039] Among them, the vertical part is provided with a longitudinal beam mounting hole 8, and the base bracket assembly 3 of the seat mounting bracket is connected to the longitudinal beam of the vehicle body through the longitudinal beam mounting hole 8; the seat mounting cross beam assembly 2 is installed on the first horizontal part; the vehicle body mounting hole 5 is provided on the second horizontal part, and the base bracket assembly 3 of the seat mounting bracket is connected to the vehicle body floor through the vehicle body mounting hole 5, and the bolt passes through the vehicle body mounting hole 5 and is connected to the vehicle body floor.

[0040] Furthermore, the above-mentioned base lower bracket 302 is welded to the entire bottom of the base upper bracket 301. The base lower bracket 302 and the base upper bracket 301 both adopt sheet metal structure, that is, the base bracket assembly 3 in this embodiment adopts a double-layer sheet metal structure, which has a large room for strength improvement and a significant effect of improving impact resistance.

[0041] Furthermore, along the length direction of the base upper bracket 301, both sides of the base upper bracket 301 are designed to be convex, which plays a certain reinforcing role.

[0042] Furthermore, the side surfaces of the seat mounting crossbeam assembly 2 and the two vertical parts are connected together by two connecting plates 1, and the connecting plates are welded to the vertical parts of the seat mounting crossbeam assembly 2 and the base bracket assembly 3, so that the overall structure is more stable and the force is more balanced.

[0043] Furthermore, the above-mentioned seat mounting bracket is arranged near the seat back. When the seat is impacted by the luggage box, the seat back tilts forward due to the impact force, thereby driving the seat mounting crossbeam. Since the base of the seat mounting bracket adopts a double-layer sheet metal structure and is connected to the seat mounting crossbeam by a connecting plate, it can withstand a large impact force, so that the forward displacement of the seat is small, and the passengers in the car have more space, thereby ensuring the safety of the passengers.

[0044] In this embodiment, the seat mounting crossbeam assembly 2 and the base support assembly 3 are connected by welding two connecting plates 1, which makes the structure more stable and the force more balanced.

[0045] When in use, the mounting bracket in this embodiment can be installed symmetrically, which is more convenient to replace and adapt to a variety of vehicle models. It can also be installed asymmetrically, depending on the actual situation.

[0046] Furthermore, the number of mounting brackets under each seat is at least two, and of course four, six, etc. can also be installed. Preferably, an even number is installed.

[0047] Example 2

[0048] This embodiment also provides a car seat having the aforementioned mounting bracket disposed on its bottom. Because the car seat has the aforementioned mounting bracket disposed on its bottom, the car seat also possesses all of the aforementioned advantages. Preferably, the aforementioned seat mounting bracket is disposed near the rear seat of the vehicle. Specifically, for a single seat, the mounting bracket is disposed near the seat backrest. When the seat is impacted by a luggage compartment, the seat backrest tilts forward due to the impact force, thereby driving the seat mounting crossbeam. Because the seat mounting bracket base utilizes a double-layer sheet metal structure and is connected to the seat mounting crossbeam via a connecting plate, it can withstand significant impact forces, minimizing the forward displacement of the seat, providing more space for vehicle occupants and thus ensuring their safety.

[0049] Example 3

[0050] This embodiment also provides a vehicle, wherein the vehicle's seats are connected using the aforementioned mounting bracket. Because the vehicle is equipped with the aforementioned mounting bracket, the vehicle also possesses all of the aforementioned advantages. In some embodiments, the vehicle provided by the present invention can be any suitable type of vehicle, such as an automobile or a new energy vehicle. The present invention is not limited to any specific vehicle type.

[0051] Specifically, the assembly diagram of the seat mounting bracket on the car is as follows: Figure 2 、 Figure 3 As shown, the front seat mounting brackets are mounted on the floor and longitudinal beams of the vehicle, and at least two are mounted under each seat, as shown in FIG. Figure 2 As shown, the two seat mounting brackets are symmetrically arranged along the width direction of the seat; wherein, the base bracket assembly 3 of the left seat mounting bracket is connected to the left longitudinal beam of the vehicle body through the longitudinal beam mounting hole 8, and the base bracket assembly 3 is connected to the left side of the vehicle body floor through the vehicle body mounting hole 5; the base bracket assembly 3 of the right seat mounting bracket is connected to the right longitudinal beam of the vehicle body through the longitudinal beam mounting hole 8, and the base bracket assembly 3 is connected to the right side of the vehicle body floor through the vehicle body mounting hole 5.

[0052] The present invention improves the rigidity of the seat mounting bracket, so that the seat can resist the impact force of the luggage box and ensure the safety of the passengers on the vehicle.
