The terms used in the specification of this application herein are only for the purpose of describing specific embodiments, and are not intended to limit this application. The term "or / and" used herein includes any and all combinations of one or more of the related listed items.

[0038] Some embodiments of the present application will be described in detail. Without conflict, the following embodiments and the features in the embodiments can be combined with each other.

[0039] In this embodiment, "a plurality of" means two, three or more than three in number.

[0040] See Figure 1 , this embodiment provides a vehicle 300, including a chassis 301 and a seat 200. The seat 200 can be set as a driver's seat 200 or a passenger seat 200, or can also be set as a seat 200 independently provided relative to the vehicle 300. The vehicle 300 further includes a body 302, and the body 302 defines an interior space 303. The seat 200 can be fixedly installed on the chassis 301 or can be disposed in the interior space 303.

[0041] Further see Figure 2 and Figure 3, the seat 200 includes a frame 201, a seat cover 202, and a buckle assembly 100. The seat cover 202 is disposed on the frame 201. The seat cover 202 can be made of a variety of materials such as fabric, leather, artificial leather, etc. The seat cover 202 is disposed on one side of the frame 201 facing the front of the vehicle 300 along the X-axis direction of the vehicle 300. The buckle assembly 100 is connected between the seat cover 202 and the frame 201 to achieve a stable connection between the seat cover 202 and the frame 201.

[0042] In some embodiments, there are multiple buckle assemblies 100. The frame 201 includes a backrest support 2011 and a headrest support 2012. The seat cover 202 includes a backrest support portion 2021 and a headrest support portion 2022. The backrest support 2011 and the backrest support portion 2021 are connected by a part of the buckle assembly 100. The headrest support 2012 and the headrest support portion 2022 are connected by another part of the buckle assembly 100.

[0043] In this embodiment, please further refer to Figure 3 , the buckle assembly 100 includes a first member 10 and a second member 20. The first member 10 is connected to or integrally formed with the frame 201. The second member 20 is connected to the seat cover 202.

[0044] In some embodiments, refer to Figure 3 , the frame 201 includes two first side edges 2017 disposed opposite to each other along its width direction. Among them, when the seat 200 is installed on the vehicle 300, the width direction of the frame 201 is the Y-axis direction of the vehicle 300 coordinate system. The first member 10 is formed on the first side edge 2017 of the frame 201, and the length direction of the first member 10 is the extension direction of the first side edge 2017. In some embodiments, the first member 10 is integrally formed with the frame 201, and the first side wall 11 is integrally formed with the main structure of the frame 201, and the second side wall 12 is integrally formed with the first side wall 11 through the bottom wall 13. In other embodiments, the first member 10 and the frame 201 are independent components, and the first side wall 11 of the first member 10 is connected to the frame 201 by fastening means such as welding and screwing.

[0045] In some embodiments, refer to Figure 3 , the seat cover 202 includes two second side edges 2023 distributed along the width direction of the seat 200. Each side edge is respectively connected with a plurality of second members 20. The plurality of second members 20 are spaced apart along the extension direction of the second side edge 2023.

[0046] In some embodiments, refer to Figure 4 and Figure 5, in some embodiments, the frame 201 includes a back plate portion 2013 and two side plate portions 2014. The two side plate portions 2014 are respectively connected to both sides of the back plate portion 2013 and are inclined relative to the back plate portion 2013. At least one first member 10 is respectively formed on the side of the two side plate portions 2014 facing away from the back plate portion 2013. The opening K1 of the first card slot C1 of the first member 10 faces the back plate portion 2013 and is open. After the seat 200 is installed on the vehicle 300, the two side plate portions 2014 extend obliquely in the direction close to the front of the vehicle 300. In this way, the back plate portion 2013 and the two side plate portions 2014 together form a semi-surrounding structure to provide better support for the user and improve the user's riding experience.

[0047] Further referring to Figure 6 and Figure 7 , the first member 10 includes a first side wall 11, a second side wall 12, a bottom wall 13 and two limiting portions 14. The first side wall 11 is spaced apart from the second side wall 12. The bottom wall 13 is connected between the first side wall 11 and the second side wall 12. The first side wall 11, the second side wall 12 and the bottom wall 13 enclose the first card slot C1. So that the two limiting portions 14 are both located in the first card slot C1, and the two limiting portions 14 are respectively connected to the first side wall 11 and the second side wall 12. Both of the two limiting portions 14 are provided with abutting surfaces P1 (as shown in Figure 7 ). The first member 10 is provided with an opening K1 penetrating through the bottom wall 13, and the opening K1 communicates with the first card slot C1. The second member 20 is connected to the face cover 202. The second member 20 is fitted in the first card slot C1. The second member 20 includes a clamping portion 21. The clamping portion 21 is located between the bottom wall 13 and the limiting portion 14. The clamping portion 21 abuts against the abutting surface P1 and is restricted by the abutting surface P1. A part of the clamping portion 21 is exposed from the opening K1.

[0048] When the buckle assembly 100 of this embodiment is assembled, the second member 20 is inserted into the first card slot C1 from the open end of the first card slot C1 and passes through the through hole K2 between the two limiting portions 14, so that the clamping portion 21 abuts against one side of the limiting portion 14 close to the bottom wall 13. In this way, the limiting portion 14 plays a reliable limiting role on the clamping portion 21, increasing the difficulty of the clamping portion 21 disengaging from the first card slot C1, ensuring the clamping stability between the first member 10 and the second member 20, and further improving the connection stability between the face cover 202 and the frame 201. When the vehicle 300 is running and the seat 200 is vibrating, the face cover 202 and the frame 201 are not easily separated or displaced relative to each other. At the same time, during the engagement process of the second member 20 and the first member 10, the opening K1 is beneficial to causing deformation between the first side wall 11 and the second side wall 12, reducing the engagement difficulty between the first member 10 and the second member 20. After the first member 10 and the second member 20 are engaged, the deformation between the first side wall 11 and the second side wall 12 disappears, enabling the first member 10 to stably engage with the second member 20. When the face cover 202 needs to be disassembled from the frame 201, since it is not easy for the face cover 202 to separate from the frame 201, it is relatively difficult to pull the second member 20 out of the first card slot C1 when the buckle assembly 100 needs to be disassembled. In this embodiment, the operator can apply a force to the clamping portion 21 away from the bottom wall 13 from the opening K1, so that the opening K1 can reduce the difficulty of the second member 20 disengaging from the first card slot C1. In this way, the buckle assembly 100 of this embodiment takes into account both the clamping stability and the disassembly and assembly convenience.

[0049] In this embodiment, the limiting portion 14 is configured as a protruding structure protruding from the first side wall 11 or the second side wall 12 toward the inner side of the first card slot C1, and the abutting surface P1 is the surface of the protruding structure close to the bottom wall 13. In other embodiments, the limiting portion 14 can also be configured as a groove formed by concave inward from the surface of the first side wall 11 or the second side wall 12, and the abutting surface P1 is the surface of the groove facing away from the bottom wall 13.

[0050] In some embodiments, the first member 10 is a plastic part, and the first member 10 and the frame 201 are of an integrally formed structure. The first member 10 and the frame 201 are integrally formed by injecting molten plastic material into the mold cavity. After designing the opening K1 at the bottom wall 13, it is beneficial to the flow of the molten plastic in the mold cavity, thereby reducing the processing difficulty of the first member 10 and the frame 201, improving the forming quality of the first member 10 and the frame 201, and facilitating the deformation of the first member 10 under the action of the opening K1 during the engagement process with the second member 20.

[0051] In some embodiments, the side plate portion 2014 and the first side wall 11 are integrally formed structures, and the second side wall 12 is located on the side of the first side wall 11 away from the other side plate portion 2014, so that the second member 20 on the face cover 202 can be easily engaged with the first member 10, reducing the assembly difficulty. In other embodiments, the second side wall 12 may also be disposed on the side of the first side wall 11 close to the other side plate portion 2014.

[0052] In some embodiments, referring to Figure 6 , the length direction of the second member 20 is parallel to the length direction of the first member 10, the length direction of the opening K1 is parallel to the length direction of the first member 10, and both ends of the second member 20 in the length direction extend into the first card slots C1 on both sides of the length direction of the opening K1. In this way, the bottom wall 13 can limit both ends of the second member 20, thereby preventing the second member 20 from completely passing through the opening K1 and ensuring that the second member 20 and the first member 10 remain in the engaged state.

[0053] In some embodiments, referring to Figure 6 , the length direction of the limiting portion 14 is parallel to the length direction of the first member 10, and the limiting portion 14 is located between both ends of the length direction of the opening K1. In this way, during the process of the second member 20 being inserted into the first card slot C1, both ends of the second member 20 in the length direction are not restricted by the limiting portion 14, thereby reducing the engagement difficulty between the second member 20 and the first member 10. In other embodiments, the limiting portion 14 may also extend along the length direction of the first member 10 to both ends of the length direction of the first member 10.

[0054] In some embodiments, referring to Figure 6 , the opening K1 also penetrates through the side of the first side wall 11 close to the bottom wall 13. The top surface of the limiting portion 14 connected to the first side wall 11 is flush with the top surface of the first side wall 11 at the opening K1. In this way, it is beneficial to reduce the processing difficulty of the first member 10.

[0055] In some embodiments, referring to Figure 6 , the first member 10 is provided with a plurality of openings K1, and the plurality of openings K1 are spaced apart along the length direction of the second member 20. A plurality of second members 20 are provided, and the plurality of second members 20 are distributed in the first card slots C1 along the length direction of the first member 10, and each second member 20 is respectively exposed from one opening K1.

[0056] In some embodiments, the plurality of second members 20 are sequentially abutted to improve the clamping stability between the face cover 202 and the frame body 201. In other embodiments, the plurality of second members 20 are spaced apart from each other to facilitate the disassembly and assembly convenience between the face cover 202 and the frame body 201.

[0057] In some embodiments, the two limiting portions 14 are configured as a limiting group, and the buckle assembly 100 includes multiple limiting groups, each limiting group corresponding to an opening K1. In other embodiments, the first member 10 may also be provided with only two limiting portions 14, and both limiting portions 14 extend to both ends of the length direction of the first member 10.

[0058] In some embodiments, see Figure 7 , each limiting portion 14 has a contact surface P1 and a guide surface P2. One side of the contact surface P1 of one limiting portion 14 is connected to the first side wall 11. One side of the contact surface P1 of another limiting portion 14 is connected to the second side wall 12, the contact surface P1 is used to limit the clamping portion 21, and the other side of the contact surface P1 is connected to the guide surface P2, the guide surface P2 is inclined relative to the contact surface P1, and the distance between the guide surface P2 and the second component 20 gradually decreases in the direction close to the contact surface P1. A through hole K2 is constructed between the two limiting portions 14. A limiting space Q is defined between the bottom wall 13 and the two limiting portions 14.

[0059] In this way, during the mating process of the second component 20 in the first slot C1, the guide surface P2 can guide the clamping part 21 to be pressed through the through hole K2 between the two limiting parts 14, and then enter the limiting space Q between the bottom wall 13 and the two limiting parts 14. After entering the limiting space Q, the clamping part 21 abuts against the abutting surfaces P1 of the two limiting parts 14, and is thereby limited in the limiting space Q by the two limiting parts 14, thereby achieving reliable clamping of the clamping part 21 and the first component 10, thereby improving the assembly convenience of the second component 20 and the first component 10.

[0060] In some embodiments, the abutting surface P1 is a plane parallel to the bottom wall 13 .

[0061] In other embodiments, see Figure 8 The abutting surface P1 can also be configured as a curved surface or an inclined surface, and the distance between the abutting surface P1 and the second member 20 gradually decreases in the direction close to the bottom wall 13, and a clamping groove is configured between the abutting surface P1 and the first side wall 11 or the second side wall 12. In this way, when the clamping portion 21 extends into the limiting space Q, the clamping portion 21 can be matched in the clamping groove, and when the clamping portion 21 is forced to escape, it will drive the limiting portion 14 to deform, and the two mutually adjacent limiting portions 14 can play a locking role, thereby increasing the difficulty of the clamping portion 21 to escape, and improving the reliability of the clamping of the first member 10 and the second member 20.

[0062] In some embodiments, see Figure 7, the second member 20 includes a connecting section 22. The clamping portion 21 includes two snap segments 23. The connecting section 22 is fitted into the first card slot C1 and is received between the two limiting portions 14. The connecting section 22 extends between the bottom wall 13 and the limiting portions 14. Both of the two snap segments 23 are located between the bottom wall 13 and the limiting portions 14. The two snap segments 23 are respectively connected to the opposite sides of the connecting section 22. Both of the two snap segments 23 are inclined relative to the bottom wall 13, and the two snap segments 23 respectively abut against the two limiting portions 14.

[0063] During the process of the second member 20 extending into the first card slot C1, the two snap segments 23 are inclined and retracted along the direction close to the connecting section 22 under the clamping of the two limiting portions 14, and gradually pass through the through hole K2. After the two snap segments 23 pass through the through hole K2, they are no longer under the action of the clamping force, so they expand relative to the connecting section 22, and then abut against the limiting portions 14. In this way, the second member 20 is restricted between the bottom wall 13 and the two limiting portions 14.

[0064] In some embodiments, referring to Figure 7 , the snap segment 23 has a connecting end 231 and an abutting end 232. The connecting end 231 is connected to the connecting section 22. The abutting end 232 is located at the other end of the snap segment 23. The abutting end 232 of one snap segment 23 abuts against the first side wall 11, and the abutting end 232 of the other snap segment 23 abuts against the second side wall 12. In this way, the acting force of the clamping portion 21 abutting against the two limiting portions 14 is relatively balanced, and the clamping stability of the second member 20 and the first member 10 is improved.

[0065] In some embodiments, the snap segment 23 abuts against the connection between the limiting portion 14 and the first side wall 11 or the second side wall 12, so as to improve the clamping effect between the snap segment 23 and the limiting portion 14.

[0066] In some embodiments, referring to Figure 8 , the number of the snap segments 23 is multiple. A plurality of snap segments 23 are respectively arranged on both sides of the connecting section 22, and the plurality of snap segments 23 on the same side of the connecting section 22 are distributed along the length direction of the connecting section 22. In this way, the possibility of the plurality of snap segments 23 disengaging from the through hole K2 can be further reduced, and the clamping stability of the second member 20 and the first member 10 is improved.

[0067] In some embodiments, referring to Figure 8, the second member 20 includes a main body portion 26 and a covering portion 27. The covering portion 27 covers the main body portion 26. The rigidity of the main body portion 26 is greater than that of the elastic portion. In this way, the strength of the second member 20 can be improved, and further the connection stability between the second member 20 and the first member 10 can be improved. The main body portion 26 can be made of a metal or other rigid material with the ability of deformation. The covering portion 27 can be made of rubber or flexible plastic, and the covering portion 27 enables the second member 20 to have better elastic deformation ability, so that it can be reliably snapped into the first card slot C1.

[0068] In some embodiments, refer to Figure 7 and Figure 8 , the second member 20 further includes a first contact portion 24 and a second contact portion 25. The first contact portion 24 and the second contact portion 25 are respectively connected to both sides of the connecting section 22. The first contact portion 24 extends toward the first side wall 11 until it abuts against the first side wall 11, and the second contact portion 25 extends toward the second side wall 12 until it abuts against the second side wall 12. Both the first contact portion 24 and the second contact portion 25 are located on the side of the limiting portion 14 away from the bottom wall 13. In this way, the difficulty of the second member 20 disengaging from the first card slot C1 can be increased, and the clamping stability between the first member 10 and the second member 20 can be improved.

[0069] In some embodiments, refer to Figure 7 , along the direction away from the bottom wall 13, the distance between the first contact portion 24 and the first side wall 11 gradually decreases, and the distance between the second contact portion 25 and the second side wall 12 remains unchanged. Thereby, the contact area between the first contact portion 24 and the first side wall 11 can be increased, and the contact area between the second contact portion 25 and the second side wall 12 can be increased, so as to increase the friction force between the first contact portion 24 and the first side wall 11, increase the friction force between the second contact portion 25 and the second side wall 12, and improve the clamping stability between the first member 10 and the second member 20.

[0070] In other embodiments, refer to Figure 8 , along the direction away from the bottom wall 13, the distance between the first contact portion 24 and the first side wall 11 gradually decreases, and the distance between the second contact portion 25 and the second side wall 12 gradually decreases.

[0071] In some embodiments, refer to Figure 7 , the frame body 201 includes a first back plate 2015 and a second back plate 2016. The first side wall 11 of the first member 10 is connected to the first back plate 2015. The second back plate 2016 is attached to the first back plate 2015. The second back plate 2016 extends into the first card slot C1, and the opposite sides of the second back plate 2016 respectively abut against the second member 20 and the first side wall 11 of the first member 10.

[0072] Thus, a connecting section C12 is formed between the second back plate 2016 and the second side wall 12. A groove section C11 is formed between the first back plate 2015 and the second side wall 12.

[0073] In other implementations, the thickness of the edge of the back plate portion 2013 may also be changed so that the first slot C1 is configured to be in a shape in which the slot section C11 and the connecting section C12 are connected.

[0074] In some embodiments, the second back plate 2016 is a decorative layer, which can be made of composite PU to improve the aesthetics of the frame 201. In other embodiments, the decorative layer can also be made of a material with elastic deformation ability to improve the clamping effect on the second component 20.

[0075] In other embodiments, Figure 7 In the illustrated buckle assembly 100, the first member 10 and the second member 20 are in the middle of being engaged. When the first member 10 and the second member 20 are fully engaged, the first contact portion 24 abuts against the surface of the second back plate 2016 close to the stopper 14, and the first contact portion 24 can also achieve the effect of reducing the possibility of the second member 20 slipping out of the first slot C1. At the same time, the second contact portion 25 abuts against one of the stoppers 14 (i.e. Figure 7 In this way, the possibility of the second member 20 completely passing through the through hole K2 can be reduced. In this way, through the mutual cooperation of the first contact portion 24, the second contact portion 25, the second back plate 2016 and the limiting portion 14, the clamping effect of the first member 10 and the second member 20 can be further improved, and the clamping stability of the buckle assembly 100 can be ensured.

[0076] In some embodiments, a projection of the second contact portion 25 on the connecting piece 30 along a direction away from the bottom wall 13 partially overlaps with a surface of the connecting piece 30 .

[0077] In some embodiments, see Figure 7, the second side wall 12 has a free end 121 facing away from the bottom wall 13. The snap component 100 further includes a connecting piece 30. The connecting piece 30 includes a first section 31, a second section 32, and a third section 33. The first section 31 extends into the first slot C1 and is connected to the second member 20. The third section 33 fits against the side of the second side wall 12 facing away from the first side wall 11. The second section 32 is connected between the first section 31 and the third section 32 and forms a second slot C2. The free end 121 extends into the second slot C2 and abuts against the second section 32. The opening direction of the second slot C2 is opposite to the opening direction of the first slot C1. In this way, the first member 10 defines the first slot C1, the second member 20 and the connecting piece 30 define the second slot C2, and the second side wall 12 is fitted into the second slot C2, and the second member 20 is fitted into the first slot C1, realizing the mutual engagement of the first member 10 and the second member 20 in the opposite direction, and further improving the engagement stability of the first member 10 and the second member 20.

[0078] In some embodiments, the connecting piece 30 is a fabric structure, and the face cover 202 is connected to the connecting piece 30 by sewing threads. One end of the second member 20 facing away from the engaging portion 21 overlaps the connecting piece 30, realizing the connection between the face cover 202 and the connecting piece 30. In other embodiments, the connecting piece 30 can also be configured as a rigid structure made of plastic, metal, etc. to improve the engagement stability between the second member 20 and the first member 10. At this time, the connecting piece 30 can be connected to the face cover 202 through other fabric structures or elastic elements to ensure the smooth assembly between the face cover 202 and the frame body 201.

[0079] In some embodiments, one end of the second member 20 facing away from the engaging portion 21 is provided with a connecting portion 28, and the connecting portion 28 is embedded in the connecting groove 34 of the connecting piece 30, so that the second member 20 is connected to the connecting portion 28. The shape of the connecting portion 28 can be configured as a T shape to reduce the possibility of the connecting portion 28 detaching from the connecting piece 30 and improve the connection stability between the second member 20 and the connecting piece 30.

[0080] In some embodiments, see Figure 7 , the second side wall 12 has a first surface P3 close to the first side wall 11 and a second surface P4 facing away from the first side wall 11. At the free end 121, the first surface P3 is a plane, and the second surface P4 is an arc surface. In this way, it can facilitate the close fit between the connecting piece 30 and the second surface P4, thereby reducing the loosening error between the connecting pieces 30 and further improving the connection stability between the face cover 202 and the frame body 201 through the snap component 100.

[0081] In some embodiments, see Figure 7, the first card slot C1 includes a slot section C11 and a connecting section C12. The connecting section C12 is connected to the slot section C11, and the width of the connecting section C12 is smaller than the width of the slot section C11. In this way, it is more difficult for the second component 20 engaged in the first card slot C1 to escape from the connecting section C12, thereby further improving the engagement stability between the first component 10 and the second component 20.
