DETAILED DESCRIPTION

[0042] In order to enable ordinary persons in the art to better understand the technical solution of the present application, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the accompanying drawings.

[0043] It should be noted that the terms "first", "second", etc. in the specification and claims of the present application and the above-mentioned drawings are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence. It should be understood that the data used in this way can be interchangeable where appropriate, so that the embodiments of the present application described herein can be implemented in an order other than those illustrated or described herein. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present application. On the contrary, they are merely examples of devices and methods consistent with some aspects of the present application as detailed in the attached claims.

[0044] With the rapid development of the automobile industry, the safety of automobiles has received more and more attention. For automobiles, vehicle seats are one of the important components, and vehicle seats are usually fixed on the crossbeam of the vehicle by seat mounting brackets.

[0045] In the related art, the seat mounting bracket generally includes a mounting hole, and the seat mounting bracket encloses a mounting cavity with an opening. The nut is located in the mounting cavity and is connected to the mounting hole by projection welding. During the installation of the seat, a bolt is generally used to pass through the mounting hole and connect with the nut, thereby fixing the seat to the seat mounting bracket. However, this technology often has the problem of poor seat installation accuracy.

[0046] Based on this, the present application provides a vehicle 10 for solving the problem of poor seat installation accuracy. The vehicle 10 can be a fuel vehicle, a new energy vehicle, or any other power-driven vehicle.

[0047] Exemplarily, the vehicle 10 may be a passenger vehicle such as a sedan, a sport utility vehicle (SUV), a multi-purpose vehicle (MPV), or may be a bus, a truck, a semi-trailer, etc., which is not particularly limited in this embodiment.

[0048] Among them, the new energy vehicle can be a pure electric vehicle, a hybrid electric vehicle, or a fuel cell electric vehicle, and this application does not make any specific restrictions on this.

[0049] For ease of understanding, the vehicle 10 provided in the present application is specifically introduced below with reference to the accompanying drawings.

[0050] See also Figure 1 , Figure 11 is a schematic diagram of a vehicle structure according to an exemplary embodiment, wherein the vehicle 10 has a cockpit 11 and a passenger compartment 12. The cockpit 11 and the passenger compartment 12 may be connected. In other embodiments, the cockpit 11 and the passenger compartment 12 may not be connected. Alternatively, in other embodiments, the vehicle 10 may not have a passenger compartment 12. Seats 20 are arranged in both the cockpit 11 and the passenger compartment 12 for the convenience of the driver and passengers.

[0051] See also Figure 2 , Figure 2 1 is a structural diagram of a seat mounting structure according to an exemplary embodiment, in which a seat 20 is mounted in a vehicle 10 through a seat mounting structure 30. Specifically, the seat mounting structure 30 includes a seat mounting crossbeam 40 and a seat mounting bracket 50. The seat mounting crossbeam 40 is used to connect to the vehicle body. The seat mounting bracket 50 is connected to the seat mounting crossbeam 40.

[0052] In this way, the seat 20 can be installed in the vehicle 10 by being mounted on the seat mounting bracket 50 .

[0053] See also Figure 3 Combined with Figure 4 , Figure 3 FIG. 1 is a schematic diagram of a structure of a seat mounting bracket according to an exemplary embodiment. Figure 4 FIG2 is a second structural schematic diagram of a seat mounting bracket according to an exemplary embodiment. Specifically, the seat mounting bracket 50 includes a bracket body 51 and a mounting member 52. The bracket body 51 forms a mounting cavity 511 with an opening 512 at one end. Such a structure has good strength and rigidity and can better support the seat 20.

[0054] The bracket body 51 is provided with a first mounting hole 513, which is in communication with the mounting cavity 511. The first mounting hole 513 is arranged opposite to the opening 512. The mounting member 52 is arranged in the mounting cavity 511. The mounting member 52 includes a nut plate 521 and a nut 522.

[0055] In the related art, the nut 522 is directly connected to the bracket body 51 by projection welding. The position of the nut 522 cannot be adjusted during the welding process. The position accuracy of the nut 522 relative to the bracket body 51 is poor, resulting in poor installation accuracy of the seat 20.

[0056] See also Figure 3 Combined with Figure 5 , Figure 5Schematic diagram of a nut plate according to an exemplary embodiment, in which a nut plate 521 is connected to a bracket body 51, and a second mounting hole 5211 is provided in the nut plate 521. A nut 522 is welded to the nut plate 521 and is located on a side of the nut plate 521 close to the opening 512. The nut 522 has a threaded hole 5221.

[0057] It is understandable that the seat 20 can be connected to the nut 522 through the first mounting hole 513 and the second mounting hole 5211 , so that the seat 20 is installed on the bracket body 51 .

[0058] Exemplarily, the nut 522 and the nut plate 521 can be welded by projection welding, wherein along the axial direction of the threaded hole 5221, the projection of the threaded hole 5221 on the nut plate 521 is located in the second mounting hole 5211, and the projection of the threaded hole 5221 on the bracket body 51 is located in the first mounting hole 513.

[0059] It is understandable that the inner diameter of the threaded hole 5221 is smaller than or equal to the inner diameter of the first mounting hole 513 and the second mounting hole 5211 .

[0060] In this way, in the present application, the nut 522 is welded to the nut plate 521 to form the mounting member 52, so that the mounting member 52 is connected to the bracket body 51, and the nut plate 521 and the nut 522 are connected to the bracket body 51 as a whole. In this way, during the connection between the mounting member 52 and the bracket body 51, the position of the nut 522 can be fine-tuned by adjusting the position of the nut plate 521, so that the threaded hole 5221 and the first mounting hole 513 are more accurately aligned. In this way, the position accuracy of the nut 522 relative to the bracket body 51 can be improved, thereby improving the installation accuracy of the seat 20.

[0061] It is understandable that when processing the seat mounting bracket 50, the mounting member 52 is first processed, the relative position of the threaded hole 5221 and the second mounting hole 5211 is adjusted, and the nut 522 and the nut plate 521 are welded together so that the projection of the threaded hole 5221 on the nut plate 521 along the axial direction of the threaded hole 5221 is located inside the second mounting hole 5211. Then the mounting member 52 is connected to the bracket body 51, and the position of the nut plate 521 is adjusted to achieve fine adjustment of the position of the nut 522, and then the relative position of the threaded hole 5221 and the first mounting hole 513 is adjusted, so that the threaded hole 5221 and the first mounting hole 513 are further aligned more accurately.

[0062] It should be noted that the mounting member 52 and the bracket body 51 can be connected by welding.

[0063] For example, the mounting member 52 and the bracket body 51 can be connected by spot welding. Spot welding has the advantages of high efficiency, energy saving, and good welding quality.

[0064] In some embodiments, along the axial direction of the threaded hole 5221 , the projection of the second mounting hole 5211 on the bracket body 51 is located inside the first mounting hole 513 .

[0065] In this way, the inner diameter of the second mounting hole 5211 is smaller than or equal to the inner diameter of the first mounting hole 513. It is understandable that such a configuration can guide the seat 20 to be installed when the seat 20 is installed, making the installation of the seat 20 more convenient and quick.

[0066] For example, the inner diameter of the first mounting hole 513 is larger than the inner diameter of the second mounting hole 5211, and the inner diameter of the second mounting hole 5211 is larger than the inner diameter of the threaded hole 5221. In this way, when the seat 20 is installed, the inner diameters of the first mounting hole 513, the second mounting hole 5211, and the threaded hole 5221 gradually decrease, which can guide the seat 20 and make the installation of the seat 20 more convenient.

[0067] In some embodiments, see Figure 3 The bracket body 51 includes a mounting plate 514 and a side plate 515. The first mounting hole 513 is provided on the mounting plate 514, and the nut plate 521 is connected to the mounting plate 514. The side plate 515 is located on a side of the mounting plate 514 close to the nut plate 521, and is arranged around the circumference of the mounting plate 514. The side plate 515 and the mounting plate 514 enclose a mounting cavity 511, and the end of the side plate 515 away from the mounting plate 514 encloses an opening 512.

[0068] In this way, by providing the mounting plate 514 and the side plate 515 to enclose the mounting cavity 511 , the strength and rigidity of the structure of the bracket body 51 can be improved, and the seat 20 can be better supported.

[0069] It should be noted that the mounting plate 514 can be in the form of a plate or a block. The shape of the mounting plate 514 includes but is not limited to a rectangle, a triangle, a diamond or a special shape.

[0070] Exemplarily, the mounting plate 514 is in the shape of a rectangular plate, which is more conducive to the spatial layout design of the entire bracket body 51 and further facilitates the installation of the seat 20.

[0071] Exemplarily, the mounting plate 514 and the side plate 515 can be an integrally formed part. For example, the mounting plate 514 and the side plate 515 are an integrally formed part, which is then bent and shaped after being integrally formed. This is conducive to simplifying the processing technology of the bracket body 51 and improving the connection strength between the mounting plate 514 and the side plate 515.

[0072] In other embodiments, the mounting plate 514 and the side plate 515 may also be connected by welding, riveting or screw connection.

[0073] In some embodiments, see Figure 4 The mounting plate 514 is provided with a positioning hole 5141 , and the positioning hole 5141 is located on the peripheral side of the first mounting hole 513 .

[0074] It can be understood that by providing the positioning holes 5141 on the mounting plate 514, the seat 20 can be accurately positioned during installation, which helps to simplify the installation process and improve installation efficiency.

[0075] It should be noted that the number of the positioning holes 5141 can be one, two, three or four, and this application does not make any specific limitation on this.

[0076] Exemplarily, the number of the positioning hole 5141 is one.

[0077] In some embodiments, see Figure 4 The side plate 515 includes a plurality of sub-plates 5151 and a plurality of connecting plates 5155. The plurality of sub-plates 5151 are arranged at intervals along the circumference of the mounting plate 514. Every two adjacent sub-plates 5151 are connected by a connecting plate 5155.

[0078] In this way, by configuring the side panel 515 to include a plurality of sub-panels 5151 and a plurality of connecting panels 5155 , the structure of the side panel 515 can be made more stable, the supporting strength of the side panel 515 can be improved, and the side panel 515 can be made less likely to deform.

[0079] It is worth noting that, unless otherwise specified, the term “plurality” in this document refers to two or more.

[0080] In some embodiments, see Figure 4 The plurality of sub-plates 5151 include two first fixing plates 5152 and two second fixing plates 5153. The two first fixing plates 5152 are arranged opposite to each other. The two second fixing plates 5153 are arranged opposite to each other and are located between the two first fixing plates 5152. Each connecting plate 5155 is connected to one second fixing plate 5153 and one first fixing plate 5152.

[0081] It should be noted that the connecting plate 5155 can be directly connected to the first fixing plate 5152 or the second fixing plate 5153 by welding, riveting or screws, or it can be integrally formed with one of the first fixing plate 5152 or the second fixing plate 5153 and connected to the other by welding, riveting or screws.

[0082] For example, see Figure 4The connecting plate 5155 is integrally formed with the first fixing plate 5152, and is connected to the second fixing plate 5153 by spot welding, and the second fixing plate 5153 has a welding spot 5154. The spot welding can form a uniform welding at the welding spot 5154, and the welding is firm and has good sealing, thereby ensuring the welding quality.

[0083] For example, the number of the welding points 5154 may be two, four, six, etc. This application does not make any specific limitation to this.

[0084] In this way, by forming the connecting plate 5155 and the first fixing plate 5152 or the second fixing plate 5153 as one piece, the processing technology of the bracket body 51 can be simplified and the processing and forming can be facilitated.

[0085] In some embodiments, see Figure 4 The bracket body 51 further includes two third fixing plates 516. The two third fixing plates 516 are connected to the side plate 515 and are located on the side of the side plate 515 away from the mounting cavity 511. The two first fixing plates 5152 are located between the two third fixing plates 516, and the third fixing plates 516 are connected to one end of the adjacent first fixing plates 5152 away from the mounting plate 514.

[0086] In this way, the third fixing plate 516 can be connected to the seat mounting cross beam 40 to fix the bracket body 51, so that the bracket body 51 can be installed more stably, and the installation of the seat 20 can be more stable and reliable.

[0087] In some embodiments, the third fixing plate 516 includes a plurality of connecting portions 5161 and a bending portion 5162. The plurality of connecting portions 5161 are arranged at intervals along the circumference of the mounting plate 514. Every two adjacent connecting portions 5161 are connected by a bending portion 5162. The bending portion 5162 is bent toward the direction close to the mounting plate 514.

[0088] In this way, the bracket body 51 is connected to the seat mounting cross beam 40 via the connecting portion 5161 , and the strength of the third fixing plate 516 can be increased by providing the bending portion 5162 , so that the third fixing plate 516 can be installed more stably and not easily deformed.

[0089] For example, see Figure 3 The connecting portion 5161 is provided with a welding surface 5163. In this way, the welding surface 5163 can be connected to the seat mounting cross beam 40 by spot welding.

[0090] It is understandable that the second fixing plate 5153 can also be connected to the seat mounting cross beam 40 by spot welding. This can further improve the stability between the seat mounting bracket 50 and the seat mounting cross beam 40.

[0091] The above are only specific implementations of the present application, but the protection scope of the present application is not limited thereto, and any changes or substitutions within the technical scope disclosed in the present application should be included in the protection scope of the present application. Therefore, the protection scope of the present application should be based on the protection scope of the claims.
