In this specification, the schematic representation of the above terms does not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials, or characteristics described may be combined in any one or more embodiments or examples in a suitable manner.

[0032] Reference Figure 1 , Figure 1 This is a three-dimensional diagram of a seat after some functional modules are hidden in the first embodiment of the present application. According to the seat of the first embodiment of the present application, the seat of the present application can save production costs when adapting to vehicles of different widths. It should be noted that the seat can be a front seat or a rear seat, and the seat can be a single seating position or multiple seating positions, which is not limited here. Among them, the seat includes: a seat cushion frame 100, and the seat cushion frame 100 is applied to the seat cushion part of the seat.

[0033] The seat cushion frame 100 includes a first seat cushion cross beam 110, a second seat cushion cross beam 120 and a plurality of seat cushion longitudinal beams 130. It should be understood that the first seat cushion cross beam 110, the second seat cushion cross beam 120 and the seat cushion longitudinal beam 130 can be plates or rods, which are not limited here. It should also be understood that the length direction of the first seat cushion cross beam 110 and the second seat cushion cross beam 120 corresponds to the width direction of the vehicle, and the length direction of the seat cushion longitudinal beam 130 intersects with the length direction of the first seat cushion cross beam 110. In this embodiment, the length direction of the seat cushion longitudinal beam 130 corresponds to the length direction of the vehicle, that is, it is perpendicular to the first seat cushion cross beam 110. In other embodiments, the length direction of the seat cushion longitudinal beam 130 can also be inclined at a certain angle relative to the length direction of the vehicle.

[0034] The cushion longitudinal beams 130 include a plurality of cushion longitudinal beams 130, which are fixedly connected to the second cushion cross beam 120, and at least one cushion longitudinal beam 130 is fixedly connected to the first cushion cross beam 110 and the second cushion cross beam 120, so as to realize the connection between the first cushion cross beam 110 and the second cushion cross beam 120. The length of the second cushion cross beam 120 is greater than that of the first cushion cross beam 110, and it can be understood that the width of the vehicle is adapted by the longer second cushion cross beam 120, while the first cushion cross beam 110 and the cushion longitudinal beam 130 cooperate with the second cushion cross beam 120 to ensure the structural strength of the entire cushion frame 100. Therefore, when it is necessary to adapt to vehicles of different widths, the length of the second seat cross beam 120 can be adjusted to adapt to vehicles of different widths. Since the first seat cross beam 110 is shorter than the second seat cross beam 120, the length of the first seat cross beam 110 does not need to be adjusted. Therefore, when it is necessary to adapt to vehicles of different widths, the first seat cross beam 110 does not need to be additionally adjusted. The first seat cross beam 110 has a certain versatility, so that the first seat cross beam 110 can adapt to vehicles of a certain width, thereby saving the production cost of the first seat cross beam 110 and improving production efficiency. In addition, the seat frame 100 of the present application has a simple structure and is easy to produce.

[0035] It can also be understood that when it is necessary to adapt to vehicles of different widths, since the seat cushion longitudinal beam 130 is independently provided from the first seat cushion cross beam 110 and the second seat cushion cross beam 120, when the length of the second seat cushion cross beam 120 is adjusted, the size of the seat cushion longitudinal beam 130 does not need to be adjusted accordingly, so that the seat cushion longitudinal beam 130 is also universal, further saving production costs. Therefore, in a production process, the seat cushion longitudinal beam 130 connected to the first seat cushion cross beam 110 and the second seat cushion cross beam 120 can be first assembled with the first seat cushion cross beam 110 to form a module, and then the second seat cushion cross beams 120 of different lengths can be assembled into the above module according to vehicles of different widths to improve production efficiency.

[0036] Regarding the connection method between the first seat cushion cross beam 110, the second seat cushion cross beam 120 and the seat cushion longitudinal beam 130, in the present embodiment, the first seat cushion cross beam 110, the second seat cushion cross beam 120 and the seat cushion longitudinal beam 130 are welded to each other, and in other embodiments, they can also be connected by snap-fitting or threading, which is not limited here.

[0037] Regarding the adjustment method of the length of the second cushion cross beam 120, in this embodiment, the length of the second cushion cross beam 120 can be adjusted during the production process. For example, the second cushion cross beam 120 is cut from a longer round tube, and the length of the cut second cushion cross beam 120 is adjusted by the cutting position. In other embodiments, the second cushion cross beam 120 can be set as a telescopic rod, and the size of the second cushion cross beam 120 can be adjusted by extending or shortening the second cushion cross beam 120; or the second cushion cross beam 120 can be set as a plurality of detachable rods, and the required length of the second cushion cross beam 120 can be achieved by assembling the number of rods.

[0038] It should be noted that, for the sake of convenience, the seat cushion longitudinal beam 130 connecting the first seat cushion cross beam 110 and the second seat cushion cross beam 120 is defined as the first seat cushion longitudinal beam 130a. Figure 1 , having two first cushion longitudinal beams 130a, and the two ends of the first cushion longitudinal beam 130a are respectively connected to the first cushion cross beam 110 and the second cushion cross beam 120. In other embodiments, there may be more than two first cushion longitudinal beams 130a to improve the structural strength; and the first cushion longitudinal beam 130a may protrude from the first cushion cross beam 110 and the second cushion cross beam 120 at both ends.

[0039] It should be noted that, since the second cushion cross beam 120 is longer than the first cushion cross beam 110, both ends of the second cushion cross beam 120 will extend beyond the first cushion cross beam 110. If the cushion longitudinal beam 130 is only connected between the first cushion cross beam 110 and the second cushion cross beam 120, that is, only the first cushion longitudinal beam 130a is provided, the structural strength of both ends of the second cushion cross beam 120 extending beyond the first cushion cross beam 110 will be low. In order to improve the structural strength of the cushion frame 100, refer to Figure 1 At least one seat cushion longitudinal beam 130 is connected to the end of the second seat cushion cross beam 120 or to a position close to the end of the second seat cushion cross beam 120, so that the seat cushion longitudinal beam 130 is connected to the position of the second seat cushion cross beam 120 beyond the first seat cushion cross beam 110, and a gap 131 is formed between the seat cushion longitudinal beam 130 and the first seat cushion cross beam 110, thereby improving the structural strength of the position of the second seat cushion cross beam 120 beyond the two ends of the first seat cushion cross beam 110, so as to improve the structural strength of the seat cushion frame 100.

[0040] For the convenience of description, the seat cushion longitudinal beam 130 connected to the second seat cushion cross beam 120 and forming a gap 131 with the first seat cushion cross beam 110 is defined as the second seat cushion longitudinal beam 130b. Figure 1, having two second cushion longitudinal beams 130b, and the two second cushion longitudinal beams 130b are respectively arranged at both ends of the second cushion cross beam 120, thereby enhancing the structural strength of both ends of the second cushion cross beam 120. In other embodiments, the second cushion longitudinal beams 130b may also include more than two to further improve the structural strength.

[0041] In order to facilitate the installation of the cushion longitudinal beam 130, refer to Figure 1 The seat cushion longitudinal beam 130 is provided with a mounting hole (not shown in the figure), and the second seat cushion cross beam 120 is passed through the mounting hole.

[0042] It is understandable that during the installation process of the cushion longitudinal beam 130 and the second cushion cross beam 120, the second cushion cross beam 120 can be first passed through the installation hole so that the cushion longitudinal beam 130 can slide relative to the second cushion cross beam 120, thereby facilitating the adjustment of the installation position of the cushion longitudinal beam 130, and the hole wall of the installation hole plays a certain role in limiting the cushion longitudinal beam 130 to prevent the cushion longitudinal beam 130 from coming off the second cushion cross beam 120. After determining the installation position of the cushion longitudinal beam 130, the cushion longitudinal beam 130 is welded to the second cushion cross beam 120 to complete the installation between the cushion longitudinal beam 130 and the second cushion cross beam 120.

[0043] In order to facilitate sitting, the seat frame 100 of the present application also includes a plurality of seat panels 140, which can support passengers when they sit on the seat of the present application. Figure 1 At least two seat cushion longitudinal beams 130 are connected to the first seat cushion cross beam 110 and the second seat cushion cross beam 120 , that is, at least two first seat cushion longitudinal beams 130 a are provided, and a seat plate 140 is correspondingly provided between two adjacent seat cushion longitudinal beams 130 .

[0044] It can be understood that since the first seat cushion longitudinal beam 130a connects the first seat cushion cross beam 110 and the second seat cushion cross beam 120, when it is necessary to adjust the length of the second seat cushion cross beam 120, the connection position of the first seat cushion longitudinal beam 130a compared to the first seat cushion cross beam 110 and the second seat cushion cross beam 120 can remain relatively unchanged. Therefore, the distance between two adjacent first seat cushion longitudinal beams 130a remains unchanged, and therefore the width of the seat plate 140 arranged between the first seat cushion longitudinal beams 130a does not need to be adjusted, thereby further saving production costs.

[0045] In addition, a seat plate 140 is also provided between the second seat cushion longitudinal beam 130b and the first seat cushion longitudinal beam 130a. It should be understood that when the length of the second seat cushion cross beam 120 is adjusted, the installation position of the second seat cushion longitudinal beam 130b also needs to be adjusted accordingly, thereby the spacing between the second seat cushion longitudinal beam 130b and the adjacent first seat cushion longitudinal beam 130a will change, and the size of the seat plate 140 between the second seat cushion longitudinal beam 130b and the first seat cushion longitudinal beam 130a will need to be adjusted accordingly.

[0046] For example, in this embodiment, refer to Figure 1 , the seat of the present application is applied to the rear row of the vehicle, thus, the seat of the present application has three seating positions. It should be understood that each seat plate 140 corresponds to one seating position, and each of two cushion longitudinal beams 130 corresponds to one seating position. The first cushion longitudinal beam 130a and the second cushion longitudinal beam 130b each include two, and the second cushion longitudinal beam 130b is respectively arranged at the two ends of the second cushion cross beam 120, a seat plate 140 is arranged between the two first cushion longitudinal beams 130a, and a seat plate 140 is also respectively arranged between the two second cushion longitudinal beams 130b and the first cushion longitudinal beams 130a adjacent thereto. Of course, in other embodiments, the seat can also be applied to the front row of seats, and one seating position can also correspond to multiple seat plates 140 and more than two cushion longitudinal beams 130.

[0047] Regarding the installation method of the seat plate 140, in this embodiment, refer to Figure 1 The seat plate 140 is welded to the second seat cushion cross beam 120 and the seat cushion longitudinal beam 130 respectively. In other embodiments, the seat plate 140 may also be threadedly connected to the second seat cushion cross beam 120 and the seat cushion longitudinal beam 130, or may only be connected to the second seat cushion cross beam 120 or the seat cushion longitudinal beam 130.

[0048] In order to facilitate the installation of the seat cushion frame 100, refer to Figure 1 The seat cushion frame 100 also includes a plurality of first mounting structures 150 . The first mounting structures 150 are disposed on the seat cushion longitudinal beam 130 and / or the second seat cushion cross beam 120 and are used to be connected to the vehicle body 400 .

[0049] It is understandable that the seat cushion frame 100 is connected to the vehicle body 400 via the first mounting structure 150. Since the seat cushion longitudinal beam 130 and the first seat cushion cross beam 110 do not need to be adjusted in size when adapting to vehicles of different widths, the first mounting structure 150 is arranged on the seat cushion longitudinal beam 130 and / or the first seat cushion cross beam 110, so that the installation position of the first mounting structure 150 relative to the seat cushion longitudinal beam 130 and / or the first seat cushion cross beam 110 does not need to be adjusted, thereby improving production efficiency.

[0050] For example, in this embodiment, refer to Figure 1The first mounting structure 150 is disposed on the seat cushion longitudinal beam 130. Since the seat cushion longitudinal beam 130 does not need to be adjusted in size when adapting to vehicles of different widths, the mounting position of the first mounting structure 150 relative to the seat cushion longitudinal beam 130 remains unchanged. There is no need to make additional adjustments to the structure or operating parameters of the production line for producing seats, which can further save costs and improve production efficiency.

[0051] It should also be noted that the installation positions of the corresponding seat cushion frames 100 on vehicles of different widths are different. By providing a first installation structure 150 on each of the second seat cushion longitudinal beams 130b, when the length of the second seat cushion cross beam 120 is adjusted, the installation position of the second seat cushion longitudinal beam 130b relative to the second seat cushion cross beam 120 is adjusted, and the relative distance between the two second seat cushion longitudinal beams 130b will change, thereby changing the distance between the first installation structures 150 on the two second seat cushion longitudinal beams 130b, so that when the relative position of the second seat cushion longitudinal beam 130b and the second seat cushion cross beam 120 is adjusted, the first installation structure 150 can be simultaneously adapted to the installation position on the vehicle.

[0052] In other embodiments, the first mounting structure 150 may also be simultaneously disposed on the seat cushion longitudinal beam 130 , the first seat cushion cross beam 110 and the second seat cushion cross beam 120 to improve the connection stability between the seat cushion frame 100 and the vehicle body 400 , or may be only disposed on the seat cushion longitudinal beam 130 , the first seat cushion cross beam 110 or the second seat cushion cross beam 120 .

[0053] Regarding the specific form of the first mounting structure 150, in this embodiment, refer to Figure 1 The first mounting structure 150 includes a support leg, one end of which is connected to the seat cushion longitudinal beam 130 or the second seat cushion cross beam 120, and the other end is connected to the vehicle body 400. In addition, the first mounting structure 150 may include one or more support legs, which is not limited here. In other embodiments, the first mounting structure 150 may also be a guide rail assembly to enable the seat cushion frame 100 to move relative to the vehicle body 400.

[0054] It should be noted that, in the prior art, the backrest frame and the seat cushion frame can rotate relative to each other, and therefore, a number of steel plates need to be welded on the backrest frame 200 to ensure the strength of the backrest frame 200 .

[0055] In some embodiments, the seat further includes a backrest frame 200, which is applied to the backrest of the seat, and the backrest is used to support the back of the passenger. The backrest frame 200 is fixedly connected to the seat cushion frame 100, that is, the backrest frame 200 cannot rotate relative to the seat cushion frame 100, and the backrest frame 200 is used to be fixedly connected to the vehicle body 400. Specifically, the backrest frame 200 and the frame inside the vehicle body 400 are welded. It can be understood that by fixing the backrest frame 200 relative to both the seat cushion frame 100 and the vehicle body 400, the strength of the backrest frame 200 can be improved, so as to improve the structural strength of the seat of the present application. Therefore, in the present application, the strength of the backrest frame 200 can be ensured without the need for additional steel plates.

[0056] For example, regarding a specific application scenario of the seat of the present application, the seat of the present application is suitable for use in operating vehicles, such as taxis, online car-hailing vehicles and shared cars, and the safety of operating vehicles is more important than their comfort. The seat of the present application can be used in the rear seats of operating vehicles. The backrest frame 200 and the cushion frame 100 of the seat of the present application are fixedly connected to the vehicle body 400, and the front and rear position of the seat and the tilt angle of the backrest are not adjustable, thereby improving the assembly strength of the seat and reducing the manufacturing cost of the seat.

[0057] For the specific structure of the backrest frame 200, refer to Figure 1 The backrest frame 200 includes a backrest crossbeam 210 and a backrest longitudinal beam 220 . The backrest longitudinal beam 220 is connected to the backrest crossbeam 210 . The backrest crossbeam 210 or the backrest longitudinal beam 220 is connected to the seat cushion frame 100 .

[0058] For example, in this embodiment, refer to Figure 1 , the back cross beam 210 and the back longitudinal beam 220 each include two, and the two back longitudinal beams 220 are respectively arranged at the two ends of the back cross beam 210, so that the back cross beam 210 and the back longitudinal beam 220 enclose a frame-shaped structure. In other embodiments, only one back longitudinal beam 220 and one back cross beam 210 may be included, and the back longitudinal beam 220 is connected to the middle of the back cross beam 210 to form a T-shaped structure; or in order to improve the structural strength, the back cross beam 210 and the back longitudinal beam 220 each include more than two.

[0059] It is understandable that the backrest cross beam 210 and the backrest longitudinal beam 220 are separately provided, so that when the backrest frame 200 needs to adapt to vehicles of different widths, the length of the backrest cross beam 210 can be adjusted to make the backrest cross beam 210 adapt to vehicles of different widths. At the same time, the length of the backrest longitudinal beam 220 does not need to be adjusted, and only the installation position of the backrest longitudinal beam 220 relative to the backrest cross beam 210 needs to be adjusted. Thus, the backrest longitudinal beam 220 can adapt to vehicles of different widths, making the backrest longitudinal beam 220 have a certain versatility, thereby reducing production costs and improving production efficiency. In addition, the backrest frame 200 has a simple structure and is easy to produce.

[0060] Regarding the adjustment method of the length of the backrest crossbeam 210, in this embodiment, the length of the backrest crossbeam 210 can be adjusted during the production process. For example, the backrest crossbeam 210 is cut from a longer round tube, and the length of the cut backrest crossbeam 210 can be adjusted by adjusting the cutting position. In other embodiments, the backrest crossbeam 210 can be set as a telescopic rod, and the size of the backrest crossbeam 210 can be adjusted by extending or shortening the backrest crossbeam 210; or the backrest crossbeam 210 can be set as a plurality of detachable rods, and the required length of the backrest crossbeam 210 can be achieved by assembling the number of rods.

[0061] Regarding the connection form of the backrest frame 200 and the seat cushion frame 100, in this embodiment, refer to Figure 1 , one end of the backrest longitudinal beam 220 close to the cushion frame 100 passes through the backrest cross beam 210, so that the end of the backrest longitudinal beam 220 close to the cushion frame 100 is welded to the second cushion longitudinal beam 130b, and the backrest longitudinal beam 220 corresponds to the second cushion longitudinal beam 130b one by one, so as to simplify the connection. In other embodiments, the backrest longitudinal beam 220 can also be connected to the first cushion cross beam 110 or the first cushion longitudinal beam 130a, or the backrest cross beam 210 is connected to the first cushion cross beam 110, the first cushion longitudinal beam 130a or the second cushion longitudinal beam 130b, and can also be connected by other means such as threaded connection, which is not limited here.

[0062] Specifically, the seat of the present application is applied to the rear seat and has a certain length. Therefore, in order to improve the structural strength of the backrest frame 200, in this embodiment, referring to Figure 1 The backrest frame 200 further includes a reinforcing beam 260, which connects the two backrest cross beams 210 and is located between the two backrest longitudinal beams 220 to strengthen the strength of the backrest frame 200. In addition, in order to improve the support force of the seat on the passenger's back, the backrest frame 200 further includes a mesh structure 270, which can be arranged between the backrest longitudinal beams 220 and the reinforcing beam 260. When there are multiple reinforcing beams 260, the mesh structure 270 can also be arranged between two adjacent reinforcing beams 260 at the same time.

[0063] In order to facilitate the installation of the backrest frame 200, refer to Figure 1 The backrest frame 200 further includes a second mounting structure 230 , which is disposed on the backrest longitudinal beam 220 and is used for connecting with the vehicle body 400 .

[0064] It is understandable that the backrest frame 200 is connected to the vehicle body 400 via the second mounting structure 230. Since the backrest longitudinal beam 220 does not need to be adjusted in size when adapting to vehicles of different widths, the second mounting structure 230 is arranged on the backrest longitudinal beam 220, so that the installation position of the second mounting structure 230 relative to the backrest longitudinal beam 220 does not need to be adjusted, and there is no need to adjust the structure or operation parameters of the production line for producing seats, which can further save costs and improve production efficiency.

[0065] It should be noted that the installation position of the corresponding backrest frame 200 on vehicles of different widths is different. By providing a second installation structure 230 on each backrest longitudinal beam 220, when the backrest cross beam 210 is adjusted in length, the installation position of the backrest longitudinal beam 220 relative to the backrest cross beam 210 is adjusted, and the relative distance between the two backrest longitudinal beams 220 will change, thereby changing the distance between the second installation structures 230 on the two backrest longitudinal beams 220, so that when the relative position of the backrest longitudinal beam 220 and the backrest cross beam 210 is adjusted, the second installation structure 230 can be adapted to the installation position on the vehicle at the same time.

[0066] Regarding the specific form of the second mounting structure 230, in this embodiment, the second mounting structure 230 includes a mounting bracket, one end of which is connected to the backrest longitudinal beam 220, and the other end of which extends in a direction away from the backrest longitudinal beam 220 and can be welded to the vehicle body 400. In other embodiments, the second mounting structure 230 can also be a locking structure that is snap-fitted to the vehicle body 400.

[0067] To prevent items from falling from the gap between the seat and the interior panel 410 of the vehicle to the bottom of the seat, making it difficult to remove. Figure 3 , Figure 3 This is a cross-sectional view of a seat of the first embodiment of the present application, wherein a filling layer 240 is provided on the backrest frame 200, and a decorative layer 250 is covered on the outer side of the filling layer 240, and a portion of the filling layer 240 is located at the end of the backrest frame 200 in the length direction so that the decorative layer 250 can abut against the interior trim panel 410 inside the vehicle body 400.

[0068] It can be understood that the end of the backrest frame 200 in the length direction is close to the interior panel 410 inside the vehicle body 400. By partially extending the filling layer 240 to the end of the backrest frame 200 in the length direction, part of the filling layer 240 is located between the backrest frame 200 and the interior panel 410 and squeezes the interior panel 410. Since the outer side of the filling layer 240 is covered with the decorative layer 250, the decorative layer 250 is abutted against the interior panel 410, thereby reducing the generation of gaps and reducing the possibility of objects falling from the gaps.

[0069] For example, the filling layer 240 is made of foam, sponge, or silicone, and the decoration layer 250 is made of genuine leather, fabric, or imitation leather.

[0070] In order to increase the effect of the seat of the present application, refer to Figure 1 and Figure 2 , Figure 2 This is a three-dimensional diagram of a seat according to an embodiment of the first aspect of the present application, wherein the seat further includes a plurality of functional modules 300 , and the functional modules 300 include one or more of an airbag 310 , a cup holder 320 , a seat belt assembly 330 , and a child seat restraint structure 340 .

[0071] Regarding the installation position of the child seat restraint structure 340, refer to Figure 1 The child seat restraint structure 340 is installed on the first seat cushion cross beam 110. Specifically, both ends of the first seat cushion cross beam 110 protrude from the first seat cushion longitudinal beam 130a. The child seat restraint structure 340 is installed at both ends of the first seat cushion cross beam 110. Since a gap 131 is formed between the two ends of the first seat cushion cross beam 110 and the second seat cushion longitudinal beam 130b, a larger installation space is provided to facilitate the installation of the child seat restraint structure 340 to the first seat cushion cross beam 110, thereby avoiding interference of the second seat cushion longitudinal beam 130b with the installation of the child seat restraint structure 340.

[0072] For the installation position of the airbag 310, refer to Figure 2 The airbags 310 are arranged at both ends of the backrest frame 200 in the length direction.

[0073] For the installation position of the cup holder 320, refer to Figure 2 The cup holder 320 is rotatably disposed on the backrest frame 200 so as to be flipped relative to the backrest frame 200 , thereby making the end of the cup holder 320 away from the seat cushion frame 100 approach or move away from the seat cushion frame 100 .

[0074] Regarding the installation position of the seat belt assembly 330 , the seat belt assembly 330 is disposed on the backrest frame 200 .

[0075] The vehicle according to the second aspect embodiment of the present application includes: the seat of the first aspect embodiment.

[0076] It should be noted that the vehicle can be a private car, such as a sedan, SUV, MPV or pickup truck, etc. The vehicle can also be an operating vehicle, such as a van, bus, small truck or large trailer, etc. Also, the vehicle can be a gasoline 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.

[0077] It can be understood that the seat of the first embodiment can save production costs when adapting to vehicles of different widths. Therefore, the vehicle of the second embodiment using the above-mentioned seat can save production costs.
