[0031] Currently, with the increasing prevalence of passenger cars in families, public awareness of travel safety is also increasing year by year, leading to a rise in the usage rate of child safety seats. Child safety seats are typically connected to the metal frame on the back of the rear seats via a bracket, making the bracket used to connect the child safety seat particularly important. However, existing brackets have relatively low strength, both in themselves and in their connection with the metal frame.

[0032] To address the related technical problems, this application provides a vehicle including a vehicle seat, which provides suitable support and restraint to reduce the impact of a collision on a child's body.

[0033] To address the related technical problems, this application provides a vehicle seat, which includes a seat, a seat back, and a connecting component described below. The connecting component is used to connect the seat back to the seat. The seat may refer to a child safety seat connected to the seat back, and the seat back may refer to the backrest that is provided with the vehicle seat.

[0034] To address the related technical problems, this application provides a connection component, please refer to [link to relevant documentation]. Figures 1 to 3 , Figure 1 This is a structural schematic diagram of one embodiment of the connection component provided in the application. Figure 2 yes Figure 1 The diagram shows the structure of the connecting assembly excluding the first and second connecting covers. Figure 3 yes Figure 1 The connecting component shown is a cross-sectional view along the OO direction.

[0035] The connecting assembly 1 includes a bracket body 10 and a seat connector 20. The bracket body 10 includes a connecting back plate 100, which includes a backrest connecting portion 110 and a bracket extension portion 120. One end of the backrest connecting portion 110 is used to connect with the seat back 30, and the other end of the backrest connecting portion 110 is connected with the bracket extension portion 120. The bracket extension portion 120 extends along a first direction A. The seat connector 20 includes a first connecting portion 210 and a second connecting portion 220. The first connecting portion 210 extends along the first direction A and is fixed to the backrest connecting portion 110 and the bracket extension portion 120. The second connecting portion 220 is connected in the first direction A to the end of the first connecting portion 210 away from the connecting back plate 100. The second connecting portion 220 is used to connect with the seat.

[0036] The connecting component 1 is used to connect the seat to the seat backrest 30 of the vehicle body. The seat backrest 30 can be understood as the metal frame inside the backrest of the rear seat of the vehicle. Figure 1 The seat back 30 shown is just one of the crossbeams of the metal frame. The connecting assembly 1 can be connected to this crossbeam. The term "seat back 30" as used below refers to the crossbeam fixedly connected to the connecting assembly 1. The connecting assembly 1 includes a support body 10, which includes a connecting back plate 100. The connecting back plate 100 can be a flat plate. The connecting back plate 100 includes a backrest connecting portion 110 and a support extension portion 120. Both the backrest connecting portion 110 and the support extension portion 120 extend in a first direction A. The support extension portion 120 is connected to the end of the backrest connecting portion 110 near the seat, and the end of the backrest connecting portion 110 away from the support extension portion 120 is connected to the seat back 30. The first direction A in which the connecting back plate 100 extends can form an obtuse angle with the seat back 30. Therefore, when the seat applies a force in the vehicle's direction of travel to the seat back 30 through the connecting back plate 100, the connecting back plate 100 can decompose the direction of the force, thereby improving the load-bearing capacity of the seat back 30.

[0037] One end of the seat connector 20 is connected to the support body 10, and the other end of the seat connector 20 can be detachably connected to the seat. Specifically, the seat connector 20 includes a first connecting portion 210 and a second connecting portion 220. The first connecting portion 210 extends along a first direction A, giving it better bending resistance. The connecting back panel 100 includes a backrest connecting portion 110. The first connecting portion 210 is connected to the backrest connecting portion 110, and the second connecting portion 220 is connected to the end of the first connecting portion 210 away from the backrest connecting portion 110. The second connecting portion 220 is connected to the seat, so that the seat is connected to the seat back 30 in sequence through the second connecting portion 220, the first connecting portion 210, and the connecting back panel 100. Furthermore, the connecting back panel 100 also includes a bracket extension 120, which extends in the first direction A and connects to the end of the backrest connecting portion 110 near the first connecting portion 210. In addition to connecting to the backrest connector, the first connecting portion 210 also connects to the bracket extension 120 in the first direction A, thereby increasing the connection area between the first connecting portion 210 and the connecting back panel 100. This improves the connection strength between the various parts of the connecting assembly 1, and thus enhances the safety of the seat. In this embodiment, the dimension of the bracket extension 120 in the second direction B is smaller than the dimension of the backrest connecting portion 110 in the second direction B, and matches the dimension of the first connecting portion 210 in the second direction B, to reduce unnecessary material usage. The second connecting part 220 itself has a ring structure, or the second connecting part 220 cooperates with the first connecting part 210 to form a ring structure, or the second connecting part 220, the first connecting part 210, the bracket extension part 120 and / or the backrest connecting part 110 cooperate to form a ring structure, so that the ring structure can be fastened together with the conventional universal connector of the seat to adapt to the seat.

[0038] In the above-described embodiments, the seat is connected to the seat back 30 in sequence via the seat connector 20 and the support body 10. The seat connector 20 includes a first connecting portion 210, and the support body 10 includes a backrest connecting portion 110 and a support extension portion 120. The backrest connecting portion 110, the support extension portion 120, and the first connecting portion 210 all extend along the first direction A. The support extension portion 120 is connected to one end of the backrest connecting portion 110 in the first direction A, and the first connecting portion 210 is connected to both the backrest connecting portion 110 and the support extension portion 120. This increases the connection area between the seat connector 20 and the support body 10 and improves the structural strength of the connecting component 1 itself.

[0039] In some embodiments, the support extension 120 includes a protrusion 121 and a first flange 122. The protrusion 121 extends in a first direction A and is connected to one end of the backrest connection 110. The first flange 122 also extends in the first direction A and can be connected to one or both sides of the protrusion 121 in a second direction B, and the first flange 122 is vertically arranged. Exemplarily, there is one first flange 122, and one first flange 122 is connected to one side of the protrusion 121 in the second direction B. At the angle where the first flange 122 and the protrusion 121 are connected, the first connecting part 210 is located at the angle and is fixedly connected to the protrusion 121 and the first flange 122. In another example, there are two first flanges 122, which are erected and connected to both sides of the protrusion 121 in the second direction B, so that the protrusion 121 and the two first flanges 122 form a connecting groove for accommodating the first connecting part 210. The first connecting part 210 is connected to both the protrusion 121 and the two first flanges 122, thereby increasing the lateral stability of the seat connector 20. During the vehicle's turning process, the first flange 122 can support the seat connector 20 in the second direction B, reducing the risk of seat rollover.

[0040] In some embodiments, the number of bracket extensions 120 is two, and the seat connector 20 includes two first connecting portions 210 and one second connecting portion 220. The two bracket extensions 120 are spaced apart from the backrest connector 110 in the second direction B. The two first connecting portions 210 are each connected to one bracket extension 120, and the second connecting portion 220 extends in the second direction B. The two ends of the second connecting portion 220 are respectively connected to the ends of the two first connecting portions 210 away from the connecting back panel 100. The number of bracket extensions 120 is two, and the seat connector 20 includes two first connecting portions 210 and one second connecting portion 220. Two bracket extensions 120 are spaced apart in the second direction B and can be connected to both sides of the backrest connecting portion 110 to form a snap-fit ​​opening between the two bracket extensions 120 that allows them to snap into the joint of the seat. Two first connecting portions 210 are respectively supported by one bracket extension 120 and fixedly connected to their respective bracket extensions 120. The two first connecting portions 210 are also connected to the backrest connecting portion 110. The two ends of the second connecting portion 220 are respectively connected to the end of the first connecting portion 210 away from the bracket extension 120, so that the first connecting portion 210, the second connecting portion 220 and the backrest connecting portion 110 form a ring structure for snap-fit ​​connection with the seat. In this embodiment, the first connecting portion 210 can extend out of the bracket extension 120 in the first direction A. The ratio of the dimensions of the portions of the second connecting portion 220 and the first connecting portion 210 extending out of the bracket extension 120 in the first direction A to the total dimensions of the seat connector 20 in the first direction A can be in the range of 0.1 to 0.2. Specifically, the dimensions of the second connecting portion 220 and the first connecting portion 210 extending out of the bracket extension 120 can be 1cm to 2cm, so that when the seat connector 20 is subjected to force, it forms a suitable lever arm with the bracket extension 120. The length of the first connecting portion 210 can also be extended to connect with the seat, so that the seat connector 20 has better structural stability.

[0041] Furthermore, both bracket extensions 120 include a protrusion 121 and a first flange 122. The first flange 122 is vertically arranged and connected to one side of the corresponding protrusion 121 in the second direction B. The connection between the first flange 122 and the protrusion 121 is connected to the first connecting part 210. For example, both bracket extensions 120 include a protrusion 121 and a first flange 122. One bracket extension 120 may include a protrusion 121 and a first flange 122. The first flange 122 of one bracket extension 120 is erected in the second direction B on the side of the protrusion 121 away from the other bracket extension 120. The first flange 122 of the other bracket extension 120 is erected in the second direction B on the side away from the adjacent bracket extension 120. The first connecting portion 210 is connected to its respective first flange 122 and protrusion 121, thereby enhancing the lateral stability of the connecting assembly 1. As another example, both bracket extensions 120 may each include two first flanges 122 and a protrusion 121. The two first flanges 122 of each bracket extension 120 are located on both sides of the corresponding protrusion 121 in the second direction B, thereby increasing the lateral stability of the connecting assembly 1. Optionally, both bracket extensions 120 include a first flange 122 and a protrusion 121, which makes it easier to secure the seat connector 20 to the bracket extension 120.

[0042] In some embodiments, the first flange 122 extends toward the backrest connection portion 110 in the first direction A, and the two first flanges 122 are respectively connected to opposite sides of the backrest connection portion 110 in the second direction B. In addition to being connected to the protrusion 121, the first flange 122 also extends toward the backrest connection portion 110 in the first direction A, such that the two first flanges 122 are respectively connected to one side of the backrest connection portion 110 in the second direction B. This allows the first flange 122 to be simultaneously connected to both the protrusion 121 and the backrest connection portion 110 in the first direction A, thereby increasing the area of ​​the fixed connection of the first flange 122, improving the structural strength of the first flange 122, and further reducing the risk of the seat tipping over.

[0043] In some embodiments, the bracket body 10 includes a first connecting cover plate 130, which is disposed opposite to the connecting back plate 100. The first connecting cover plate 130 connects two first flanges 122 away from the connecting back plate 100 in the second direction B. The bracket body 10 also includes a first connecting cover plate 130, which is disposed opposite to and spaced apart from the connecting cover plate. Both ends of the first connecting cover plate 130 are respectively connected to the ends of a first flange 122 away from the connecting back plate 100 in the second direction B, so that the two first flanges 122 are connected as one unit through the first connecting cover plate 130. When the first flange 122 is subjected to a lateral force from the seat connector 20 in the second direction B, the first flange 122 can transmit the force to the first connecting cover plate 130, which can further improve the stability of the first flange 122. Furthermore, the two first flanges 122 are connected by the first connecting cover plate 130, so that the connecting back plate 100, the first flanges 122 and the first connecting cover plate 130 are interconnected and closed to form a cavity, thereby improving the structural strength of the connecting assembly 1, enabling the connecting assembly 1 to withstand greater forces and improving the safety of the seat. In this embodiment, the dimension of the first connecting cover plate 130 in the first direction A can match the dimension of the main body 111, that is, the projection of the end of the first connecting cover plate 130 near the bracket extension 120 on the main body 111 is located on the main body 111, so that the bracket body 10 reserves space for connection with the seat.

[0044] In some embodiments, the backrest connection portion 110 includes a main body portion 111 and a curved connection portion 112. One end of the main body portion 111 is connected to the support extension portion 120, and the other end of the main body portion 111 is connected to the curved connection portion 112. The curved connection portion 112 extends along a third direction C. The side of the curved connection portion 112 near the support extension portion 120 is connected to the side of the seat back 30 away from the support body 10. The angle between the third direction C and the first direction A is an obtuse angle. The backrest connection portion 110 may include a main body portion 111 and a curved connection portion 112. The main body portion 111 is located between the support extension portion 120 and the curved connection portion 112. The main body portion 111 and the support extension portion 120 extend in a first direction A. The curved connection portion 112 extends in a third direction C. The third direction C can be understood as the direction from the bottom of the seat back 30 to the headrest portion. The portion of the curved connection portion 112 away from the main body portion 111 in the third direction C is connected to the seat back 30. The side of the curved connection portion 112 near the support extension portion 120 is fixedly connected to the side of the seat back 30 away from the support body 10 in the first direction A. This allows the curved connection portion 112 to be in the same plane as the seat back 30, improving the fit between the curved extension portion and the seat back 30, thereby improving the connection strength between the connection component 1 and the seat back 30. Furthermore, the angle between the third direction C and the first direction A can be an obtuse angle. Specifically, when the third direction C and the seat back 30 are on the same horizontal plane, the angle between the third direction C and the first direction A can be in the range of 120° to 140°, thereby enabling the connecting assembly 1 to effectively decompose the force from the seat and improve the structural strength of the connecting assembly 1.

[0045] In some embodiments, the support body 10 includes two second flanges 123, which are respectively located on both sides of the curved connecting portion 112. The end of each second flange 123 in the third direction C, away from the main body 111, is connected to the lower side of the seat back 30 in the third direction C. The support body 10 includes two second flanges 123, which are vertically disposed on both sides of the curved connecting portion 112 in the second direction B. The two second flanges 123 are spaced apart from the end of the curved connecting portion 112 away from the first flange 122 in the third direction C, so that the curved connecting portion 112 has a portion that can be fixedly connected to the seat back 30. The end of each second flange 123 away from the main body 111 is fixedly connected to the lower side of the seat back 30 in the third direction C. The lower side of the seat back 30 in the third direction C can be understood as the side of the seat back 30 near the main body 111 in the third direction C, which is adjacent to the side connected to the curved connecting portion 112. This allows the connecting component 1 to be connected to the seat back 30 via the bent connecting part 112, and to abut against one side of the seat back 30 via the two second flanges 123, thereby improving the connection strength between the connecting component 1 and the seat back 30 and enhancing the deformation resistance of the connecting component 1.

[0046] In some embodiments, the second flange 123 is connected to the first flange 122, and the dimensions of the first flange 122 and the second flange 123 gradually increase from the end near the seat connector 20 to the end near the seat back 30. The connection between the second flange 123 and the first flange 122 means that the two second flanges 123, which are vertically disposed on both sides of the curved connecting portion 112, are respectively connected in a third direction C to the corresponding first flanges 122, which are vertically disposed on both sides of the main body portion 111. The connection of the second flanges 123 to the first flanges 122 in the third direction C allows the first flanges 122 to directly transmit force to the seat back 30 through the second flanges 123. When the connecting assembly 1 is under stress, the two second flanges 123 can be supported between the seat back 30 and the two first flanges 122, further improving the structural strength of the connecting assembly 1. Therefore, the first flange 122 and the second flange 123 can be considered as a whole. Since the radial dimension of the first connecting part 210 is smaller than the radial dimension of the metal frame of the seat back 30, the dimensions of the first flange 122 and the second flange 123 that are vertically arranged gradually increase from the end near the seat connector 20 to the end near the seat back 30. This allows the vertical dimension of the first flange 122 to match the radial dimension of the first connecting part 210, thereby improving the ability of the first flange 122 to resist lateral deformation. The dimension of the end of the second flange 123 that is far from the first flange 122 is larger, which allows the second flange 123 to have a larger contact area with the side of the seat back 30. This improves the connection strength between the connecting component 1 and the seat back 30, and also improves the structural strength of the connecting component 1 itself.

[0047] In some embodiments, the support body 10 further includes a second connecting cover plate 140, which connects the ends of two second flanges 123 on both sides of the bent connecting portion 112 that are away from the bent connecting portion 112. Since the first flange 122 is connected to the first connecting portion 210, and the first flange 122 is connected to the second flange 123, the second connecting cover plate 140 connects the ends of the two second flanges 123 away from the bent connecting portion 112, which can improve the ability of the second flanges 123 to resist lateral deformation. Lateral deformation can be understood as the second direction B, thereby reducing the risk of the seat tipping over in the second direction B. In this embodiment, the second connecting cover plate 140 can be connected to the first connecting cover plate 130 to improve the overall structural stability of the connecting assembly 1.

[0048] In some embodiments, the end of the second connecting cover 140 away from the main body 111 abuts against the lower side of the seat back 30 in the third direction C. The second connecting cover 140 may also be the same as the second flange 123, except that the end of the second connecting cover 140 away from the first connecting cover 130 in the third direction C and the second flange 123 are both connected to the lower side of the seat back 30, so that when the second connecting cover 140 is subjected to force, the end of the second connecting cover 140 away from the first connecting cover 130 can abut against the seat back 30, thereby further improving the connection strength between the connecting assembly 1 and the seat back 30. In another embodiment, the vertically erected second flange 123 may be slightly larger than the radial dimension of the metal frame of the seat back 30, so that while the second connecting cover 140 connects the two second flanges 123, the second connecting cover 140 may also extend in the direction of the third direction C toward the seat back 30, so that the side of the second connecting cover 140 near the curved connecting part 112 is fixedly connected to the side of the seat back 30 away from the curved connecting part 112, thereby placing the metal frame of the seat back 30 between the curved connecting part 112 and the second connecting cover 140, which can increase the connection area between the second connecting cover 140 and the seat back 30, and achieve the purpose of improving the connection strength between the connecting component 1 and the seat back 30.

[0049] In summary, the seat is connected to the seat back 30 in sequence via the seat connector 20 and the support body 10. The seat connector 20 includes a first connecting part 210, and the support body 10 includes a backrest connecting part 110 and a support extension part 120. The backrest connecting part 110, the support extension part 120 and the first connecting part 210 all extend along the first direction A. The support extension part 120 is connected to one end of the backrest connecting part 110 in the first direction A, and the first connecting part 210 is connected to both the backrest connecting part 110 and the support extension part 120. This increases the connection area between the seat connector 20 and the support body 10 and improves the structural strength of the connecting component 1 itself.
