Description

Technical Field

[0001] The utility model relates to the technical field of transportation tools, in particular to an automobile seat and an automobile. Background Art

[0002] With the rapid development of automobile technology, people have higher and higher requirements for the performance and comfort of automobile seats. At present, some car seats can realize the flipping of backrests, especially the back row seats. After the backrests of the back row seats are flipped forward, the storage space of the trunk can be expanded. The adjustment methods of the backrest are generally divided into manual adjustment method and electric adjustment method. Compared with the manual adjustment method, the electric adjustment method is more labor-saving and convenient. However, the backrest adjustment switch used to control the flipping of the backrest is usually set on the side of the seat itself, and in order to ensure that the position of the backrest adjustment switch is fixed, the backrest adjustment switch is generally set on the side of the seat part of the seat.

It should be noted that the concepts of "first", "second", etc. mentioned in the present utility model are only used to distinguish different devices, modules or units, and are not used to limit the order or interdependence of the functions performed by these devices, modules or units.

[0033] It should be noted that the modifications of "one" and "plurality" mentioned in the present invention are illustrative rather than restrictive, and those skilled in the art should understand that, unless otherwise clearly indicated in the context, it should be understood as "one or more".

[0034] It should be noted that in Figure 1 , Figure 5-9 In the figure, the car seat only shows the frame part of the seat, without showing the covering layer and other structures.

[0035] See also Figure 1, a car seat of an embodiment of the utility model comprises a backrest adjustment switch structure 1, a seat portion 4 and a backrest 5 hinged to the seat portion 4, the seat portion 4 is used to be installed on the vehicle floor 2 of the vehicle body structure, the backrest adjustment switch structure 1 is arranged on the vehicle body side plate 3 of the vehicle body structure, and the projection of the seat portion 4 on the vehicle body side plate 3 does not overlap with the backrest 5 adjustment switch. It can be understood that the vehicle body side plate 3 is located at the lateral end of the vehicle floor 2.

[0036] In this embodiment, the seat 4 of the automobile seat is the same as the prior art in that the seat portion 4 is arranged on the vehicle floor 2 of the vehicle body structure, and the adjustment method of the backrest 5 of the automobile seat is an electric adjustment method, that is, when the angle of the backrest 5 needs to be adjusted, it is also adjusted through the backrest adjustment switch structure 1. The difference from the prior art is that the backrest adjustment switch structure 1 is not arranged on the side of the seat portion 4, but is arranged on the body side panel 3 of the vehicle body structure, and the projection of the seat portion 4 on the body side panel 3 does not overlap with the backrest adjustment switch structure 1, that is, the backrest adjustment switch structure 1 is not arranged at a position where the body side panel 3 and the side of the seat portion 4 are opposite to each other. In this way, when the occupant needs to adjust the angle of the backrest 5 through the backrest adjustment switch structure 1, the occupant's hand does not need to extend between the side of the seat portion 4 and the body side panel 3, but can operate the backrest adjustment switch structure 1 in other relatively spacious positions in the passenger compartment, thereby improving the convenience of the occupant in operating the backrest 5 adjustment switch.

[0037] See also Figure 1 Specifically, the bottom end of the backrest 5 is hinged to the rear end of the seat 4. The bottom end of the backrest 5 refers to an end of the backrest 5 when it is not flipped to a horizontal state.

[0038] Optionally, at any angle at which the backrest 5 is flipped relative to the seat 4 , the projection of the backrest 5 on the vehicle body side panel 3 does not overlap with the backrest adjustment switch structure 1 .

[0039] In this embodiment, the position of the backrest adjustment switch structure 1 on the vehicle body side panel 3 is further limited, that is, no matter what angle the backrest 5 is flipped to relative to the seat portion 4, the projection of the backrest 5 on the vehicle body side panel 3 does not overlap with the backrest adjustment switch structure 1. In this way, no matter what angle the backrest 5 is at, the backrest adjustment switch structure 1 is neither blocked by the seat portion 4 nor by the backrest 5, further improving the convenience of the occupant's operation.

[0040] See also Figure 1-2 Optionally, the backrest adjustment switch structure 1 includes a first switch component 11 and a second switch component 12, the car seat is a rearmost seat, the first switch component 11 is located on the upper side of the armrest panel of the vehicle body side panel 3, and / or the second switch component 12 is located at the trunk of the vehicle body side panel 3.

[0041] In this embodiment, if the car has only two rows of seats, then the car seats as the last row of seats refer to the second row of seats; if the car has three rows of seats, then the car seats as the last row of seats refer to the third row of seats. In addition, the first switch assembly 11 and the second switch assembly 12 can independently control the angle adjustment of the backrest 5.

[0042] In this embodiment, when the car seat is the last row of seats, the backrest adjustment switch structure 1 includes a first switch assembly 11 and a second switch assembly 12. The first switch assembly 11 is located on the upper side of the armrest panel of the vehicle body side panel 3. When the backrest 5 is at an angle in the passenger sitting state, the first switch assembly 11 at this position is located in the front side of the backrest 5, which is convenient for the passenger to operate in the sitting state.

[0043] In this embodiment, when the car seat is the last row of seats, the second switch assembly 12 is located at the trunk of the vehicle body side panel 3. When the backrest 5 is at an angle in the passenger's sitting position, the second switch assembly 12 at this position is located at the side and rear of the backrest 5. The second switch assembly 12 at this position can be convenient for passengers in the trunk to operate. For example, when passengers store items in the trunk, if they find that the original space in the trunk is not enough, the passengers can directly operate the second switch assembly 12 in the trunk to flip the backrest 5 forward and lay flat, thereby expanding the storage space of the trunk. When passengers store items in the trunk, they do not need to run to the passenger compartment to operate the first switch assembly 11, which further improves the convenience of adjusting the backrest 5.

[0044] In other embodiments, if the car has three rows of seats, the car seat can also be a front row seat or a middle row seat. In this case, the cushion frame 41 of the car seat can move longitudinally relative to the vehicle floor 2 to adjust the front and rear position of the car seat; at the same time, in this case, no matter what position the seat portion 4 moves longitudinally to, the projection of the seat portion 4 on the vehicle body side panel 3 does not overlap with the switch structure of the backrest 5. Similarly, if the car has only two rows of seats, then the car seat can also be a front row seat.

[0062] See also Figure 1 , Figure 5-7 and Fig.10 Optionally, the car seat also includes a motor drive structure 6, which is used to drive the backrest 5 to flip relative to the seat 4, and the motor drive structure 6, the backrest adjustment switch structure 1 and the power supply of the car are connected in series to form a control loop; the second sheet metal part 413 provided at the end of the first hollow tubular frame 411 in the lateral direction is a second end sheet metal part, and the second end sheet metal part and the corresponding third sheet metal part 512 hinged thereto constitute an end sheet metal assembly, and the motor drive structure 6 is located on the side of the end sheet metal assembly close to the corresponding adjacent body side panel 3.

[0063] In this embodiment, it should be noted that, similar to the prior art, the flipping action of the backrest 5 is also specifically realized by the motor drive structure 6, and the aforementioned backrest adjustment switch structure 1 realizes the adjustment of the backrest 5 by controlling the operation of the motor drive structure 6. Since the motor drive structure 6, the backrest adjustment switch structure 1 and the power supply of the car are connected in series to form a control loop, when the backrest adjustment switch structure 1 is closed, the control loop is energized to enable the motor drive structure 6 to operate and adjust the angle of the backrest 5.

[0064] It should be noted that the specific structure of the motor drive structure 6 to flip the backrest 5 is not an improvement of the present invention, and the specific structure of the motor drive structure 6 and the connection relationship between the motor drive structure 6 and the backrest frame 51 will not be explained in detail.

[0065] Different from the prior art, the motor drive structure 6 is located on the side of the end sheet metal component close to the corresponding adjacent vehicle body side panel 3, that is, the motor drive structure 6 is located on the side of the end sheet metal component facing the outside of the vehicle in the transverse direction, rather than being arranged on the inner side of the end sheet metal component, so that the installation and disassembly of the motor drive structure 6 can be facilitated.

[0066] like Figure 5 As shown, in the end sheet metal assembly, the second end sheet metal part is closer to the corresponding adjacent body side panel 3 than the third sheet metal part 512 connected thereto. At this time, "the motor drive structure 6 is located on the side of the end sheet metal assembly close to the corresponding adjacent body side panel 3" means: the motor drive structure 6 is located on the side of the second end sheet metal part close to the corresponding adjacent body side panel 3. In other embodiments, in the end sheet metal assembly, the third sheet metal part 512 connected to the second end sheet metal part may be closer to the corresponding adjacent body side panel 3. Then, at this time, "the motor drive structure 6 is located on the side of the end sheet metal assembly close to the corresponding adjacent body side panel 3" means: the motor drive structure 6 is located on the side of the third sheet metal part 512 connected to the second end sheet metal part close to the corresponding adjacent body side panel 3.

[0067] Another embodiment of the present invention provides a car, which includes the car seat as described above.

[0068] Since the technical improvement and technical effect of the automobile are the same as those of the automobile seat, the automobile will not be described in detail.

[0069] The terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Thus, features defined as "first" and "second" may explicitly or implicitly include at least one of the features.

[0070] Although the utility model is disclosed as above, the protection scope of the utility model is not limited thereto. Those skilled in the art can make various changes and modifications without departing from the spirit and scope of the utility model, and these changes and modifications will fall within the protection scope of the utility model.
