[0005] In some embodiments, the second connector includes a first hook stop and a first extension connected to each other, the first hook stop extending in the left-right direction of the vehicle; the first extension extending toward the first body relative to the first hook stop, the first extension being connected to the first body, and the first hook stop being located in the limiting area when the seat is connected to the frame.

[0006] In some embodiments, in the height direction of the vehicle, the distance between the lower end of the first segment and the first hook stop is greater than or equal to 16.5 mm and less than or equal to 20.5 mm.

[0007] In some embodiments, in the longitudinal direction of the vehicle, the distance between the lower end of the first segment and the first hook stop is greater than or equal to 7.5 mm and less than or equal to 9.5 mm.

[0008] In some embodiments, the tilt angle of the first segment relative to the horizontal plane is greater than or equal to 55 degrees and less than or equal to 65 degrees.

[0009] In some embodiments, the second segment extends horizontally, and in the height direction of the vehicle, the distance between the second segment and the first hook stop is greater than or equal to 10 mm and less than or equal to 13 mm.

[0010] In some embodiments, the second connector further includes a second extension, which is connected to one end of the first hook portion away from the first extension portion.

Detailed Implementation

[0020] To make the objectives, technical solutions, and advantages of this application clearer, the technical solutions of this application will be clearly and completely described below in conjunction with specific embodiments and corresponding drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0021] In the description of this application, it should be noted that, unless otherwise expressly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal communication between two components. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0022] Furthermore, although the terminology used in this application is selected from commonly known and used terms, some terms mentioned in this application specification may have been selected by the applicant at his or her own discretion, and their detailed meanings are explained in the relevant sections of this description.

[0023] Furthermore, this application should be understood not only through the actual terms used, but also through the meaning implied by each term.

[0024] The technical solutions provided by the various embodiments of this application are described in detail below with reference to the accompanying drawings.

[0025] This application provides a vehicle. Exemplarily, the vehicle can be an off-road vehicle (ORV). The vehicle can be a sport utility vehicle (SUV). The vehicle can be a sedan. These will not be listed further here.

[0026] refer to Figures 1 to 8 The vehicle (not shown) provided in this application embodiment includes a seat cushion 100 and a frame 200. The seat cushion 100 includes a first main body 110, a first connecting member 120, and a second connecting member 130. The second connecting member 130 is located behind the first connecting member 120. The frame 200 includes a second main body 210, a snap-fit ​​seat 220, and a connecting hook 230. The first connecting member 120 is used to connect with the snap-fit ​​seat 220. It should be noted that the first connecting member 120 is the connecting member located on the front side of the seat cushion 100. Those skilled in the art can refer to relevant technologies to set the first connecting member 120 and the snap-fit ​​seat 220 when implementing the solution provided in this application embodiment, or they can design the first connecting member 120 and the snap-fit ​​seat 220 themselves. Therefore, the structure and connection method of the first connecting member 120 and the snap-fit ​​seat 220 will not be described in detail here.

[0027] The connecting hook 230 includes a first segment 231, a second segment 232, and a third segment 233 connected sequentially. The first segment 231 extends upward at an angle from back to front. The second segment 232 is connected to the upper end of the first segment 231 and extends backward relative to the first segment 231. The third segment 233 extends towards the second body 210 relative to the second segment 232 and is connected to the second body 210.

[0028] The first segment 231, the second segment 232, and the third segment 233 form a limiting area 230a, and the area below the first segment 231 where the connecting hook 230 is located forms an opening 230b. The opening 230b is used for the second connector 130 to pass through and enter the limiting area 230a to connect with the connecting hook 230, or for the second connector 130 to pass through and exit the limiting area 230a to disengage from the connecting hook 230.

[0029] In this way, in the embodiments of this application, when the vehicle is subjected to an impact force, for example, during the process of the seat 100 moving backward relative to the frame 200, the second connector 130 of the seat 100 is limited to the limiting area 230a of the connecting hook 230. This can prevent the rear side of the seat 100 from separating from the frame 200, thereby improving the connection reliability between the seat 100 and the frame 200.

[0030] Furthermore, since the first segment 231 of the connecting hook 230 extends upward at an angle from back to front, the first segment 231 of the connecting hook 230 can act as a guide during the installation of the seat cushion 100, thereby allowing the second connector 130 of the seat cushion 100 to slide into the limiting area 230a of the connecting hook 230 more effectively.

[0031] It should be noted that, for example, during the installation of the seat cushion 100, the seat cushion 100 can be placed in the installation position first. When the seat cushion 100 is in the installation position, the first connector 120 is located above the snap-fit ​​seat 220, and the second connector 130 is located in front of the first segment 231 of the connecting hook 230.

[0032] Furthermore, the first connector 120 can be connected to the snap-fit ​​seat 220 by pressing the portion of the seat 100 located above the first connector 120.

[0033] Furthermore, by pushing the seat cushion 100 from front to back, the second connector 130 can slide diagonally downward under the guidance of the first segment 231 of the connecting hook 230. This allows the second connector 130 to pass through the opening 230b and enter the limiting area 230a, thereby connecting the second connector 130 with the connecting hook 230.

[0034] For example, during the removal of the seat cushion 100, the second connector 130 can be disengaged from the limiting area 230a, pass through the opening 230b, and detach from the connector 230 by pressing the portion of the seat cushion 100 above the connecting hook 230 and pushing the seat cushion 100 from back to front.

[0035] Furthermore, the first connector 120 can be disengaged from the snap-fit ​​seat 220 by pulling on the area near the first connector 120 of the seat cushion 100. If the snap-fit ​​seat 220 has a latch, the latch can be released first, and then the first connector 120 can be disengaged from the snap-fit ​​seat 220 by pulling on the area near the first connector 120 of the seat cushion 100.

[0036] Therefore, the solution provided in this application embodiment allows for convenient installation of the seat cushion 100 onto the vehicle frame 200 and convenient removal of the seat cushion 100 from the vehicle frame 200. This reduces the assembly difficulty of the seat cushion 100, saves installation time, and lowers the vehicle's installation cost. Furthermore, the seat cushion 100 is easy to disassemble and maintain during later vehicle use.

[0037] To facilitate those skilled in the art in implementing the solutions provided in the embodiments of this application, the following provides a more detailed description of the construction of the second connector 130 for reference.

[0038] refer to Figure 2 , Figure 3 and Figure 8 In some embodiments, the second connector 130 includes a first hook stop 131 and a first extension 132 connected to each other. The first hook stop 131 extends in the left-right direction of the vehicle. The first extension 132 extends relative to the first hook stop 131 toward the first body 110 and is connected to the first body 110. When the seat cushion 100 is connected to the frame 200, the first hook stop 131 is located in the limiting area 230a. Thus, the second connector 130 can limit the rear side of the seat cushion 100 by limiting the first hook stop 131 to the limiting area 230a.

[0039] In some embodiments, the second connector 130 further includes a second extension 133. The second extension 133 is connected to one end of the first hook stop 131 opposite to the first extension 132. The second extension 133 extends toward the first body 110 relative to the first hook stop 131 and is connected to the first body 110. When the seat 100 is connected to the frame 200, the first segment 231 is located between the first extension 132 and the second extension 133. In this way, by clamping the first segment 231 of the connecting hook 230 between the first extension 132 and the second extension 133 of the second connector 130, the seat 100 is prevented from deflecting relative to the frame 200 and disengaging from the connecting hook 230 of the frame 200.

[0040] In some embodiments, a flexible sleeve 134 is fitted onto the first hook stop 131. Exemplarily, the flexible sleeve 134 is a silicone sleeve. This way, by fitting the flexible sleeve 134 onto the first hook stop 131, abnormal noise can be avoided when the first hook stop 131 scrapes against the connecting hook 230 of the frame 200.

[0041] In some embodiments, the second connector 130 is formed by bending a metal wire. The second connector 130 is U-shaped. The end of the second connector 130 facing the first body 110 can be welded to the first body 110. Alternatively, the end of the second connector 130 facing the first body 110 is connected to a support, and the support has a mounting hole. Thus, the second connector 130 can be fixedly connected to the first body 110 using a threaded connector passing through the mounting hole. Exemplarily, the cross-section of the second connector 130 is circular. The diameter of the cross-section of the second connector 130 is greater than or equal to 4 mm and less than or equal to 6 mm. For example, the diameter of the cross-section of the second connector 130 is 5 mm.

[0042] refer to Figure 1 , Figure 6 and Figure 7 In some embodiments, the first connector 120 includes a second hook stop 121 and a third extension 122. The second hook stop 121 extends in the left-right direction of the vehicle. The third extension 122 extends relative to the second hook stop 121 toward the first body 110 and is connected to the first body 110. When the seat cushion 100 is connected to the frame 200, the second hook stop 121 engages with the telescopic piece 221 of the latching seat 220. In this way, the first connector 120 can limit the front side of the seat cushion 100 by engaging the second hook stop 121 with the telescopic piece 221 of the latching seat 220.

[0043] In some embodiments, the first connector 120 further includes a fourth extension 123. The fourth extension 123 is connected to one end of the second hook stop 121 opposite to the third extension 122. The fourth extension 123 extends toward the first body 110 relative to the second hook stop 121 and is connected to the first body 110. When the seat 100 is connected to the frame 200, the telescopic tab 221 of the snap-fit ​​seat 220 is located between the third extension 122 and the fourth extension 123. In this way, the seat 100 is prevented from deflecting relative to the frame 200 by the telescopic tab 221 of the snap-fit ​​seat 220 being sandwiched between the third extension 122 and the fourth extension 123 of the first connector 120.

[0044] In some embodiments, the first connector 120 is formed by bending metal wire. The first connector 120 is U-shaped. The end of the first connector 120 facing the first body 110 can be welded to the first body 110. Alternatively, the end of the first connector 120 facing the first body 110 is connected to a support, and the support has a mounting hole. Thus, the first connector 120 can be fixedly connected to the first body 110 using a threaded connector passing through the mounting hole. Exemplarily, the cross-section of the first connector 120 is circular. The diameter of the cross-section of the first connector 120 is greater than or equal to 4 mm and less than or equal to 6 mm. For example, the diameter of the cross-section of the first connector 120 is 5 mm.

[0045] It should be noted that the telescopic tab 221 can extend and retract relative to the second main body 210 of the frame 200 in the longitudinal direction of the vehicle. For example, during the process of inserting the first connector 120 into the locking seat 220, the telescopic tab 221 can retract relative to the second main body 210 of the frame 200 and then pop out, thereby engaging with the first connector 120. During the process of removing the first connector 120 from the locking seat 220, the telescopic tab 221 can retract relative to the second main body 210 of the frame 200 and then pop out, allowing the first connector 120 to "pass over" the telescopic tab 221 and disengage from the locking seat 220.

[0046] In some embodiments, the end of the telescopic piece 221 is provided with a first wedge-shaped guide surface and a second wedge-shaped guide surface. During the insertion of the first connector 120 into the latching seat 220, the second hook stop 121 pushes against the upper first wedge-shaped guide surface, thereby causing the telescopic piece 221 to retract. During the removal of the first connector 120 from the latching seat 220, the second hook stop 121 pushes against the lower second wedge-shaped guide surface, thereby causing the telescopic piece 221 to retract.

[0047] In some embodiments, the snap-fit ​​seat 220 further includes a sleeve and an elastic element. The telescopic tab 221 is slidably connected to the sleeve, and the telescopic tab 221 is elastically connected to the sleeve via the elastic element. In this way, the elastic element can apply an elastic force to the telescopic tab 221, causing the telescopic tab 221 to extend.

[0048] In some embodiments, the telescopic tab 221 is also connected to a toggle member. Before the first connector 120 is pulled out of the latch seat 220, the telescopic tab 221 can be retracted by manipulating the toggle member.

[0049] In some embodiments, the seat cushion 100 includes a plurality of first connectors 120, and the frame 200 includes a plurality of snap-fit ​​seats 220. The plurality of snap-fit ​​seats 220 are spaced apart along the left-right direction of the vehicle. The first connectors 120 are used to connect to the snap-fit ​​seats 220 one-to-one. For example, the number of first connectors 120 is two, and the number of snap-fit ​​seats 220 is equal to the number of first connectors 120, which is also two.

[0050] In some embodiments, the seat cushion 100 includes a plurality of second connectors 130, and the frame 200 includes a plurality of connecting hooks 230. The plurality of connecting hooks 230 are spaced apart along the left-right direction of the vehicle. The second connectors 130 are used to connect to the connecting hooks 230 in a one-to-one correspondence. For example, the number of second connectors 130 is two, and the number of connecting hooks 230 is equal to the number of second connectors 130, which is also two.

[0051] refer to Figure 8 In some embodiments, the distance A1 between the lower end of the first segment 231 and the first hook stop 131 in the height direction of the vehicle is greater than or equal to 16.5 mm and less than or equal to 20.5 mm. For example, the distance A1 between the lower end of the first segment 231 and the first hook stop 131 in the height direction of the vehicle is 18.5 mm.

[0052] In this way, when a passenger is sitting on the seat cushion 100, the seat cushion 100 will not drop excessively under the downward pressure generated by the passenger's weight, causing the first hook stop 131 of the second connector 130 to retract from the limiting area 230a of the connector 230 and move to a position opposite to the opening 230b of the connector 230.

[0053] In other words, when a passenger is seated on the seat cushion 100, the passenger's weight causes the first hook stop 131 of the second connector 130 to descend with the seat cushion 100. Because the length of the first segment 231 of the connecting hook 230 is appropriate, the first hook stop 131 will not descend below the first segment 231 of the connecting hook 230. This prevents the first hook stop 131 from descending excessively due to the passenger's weight, thus avoiding the first hook stop 131 from moving forward with the seat cushion 100 and disengaging from the connecting hook 230 of the frame 200 in the event of an impact.

[0054] In addition, the length of the first section 231 of the connecting hook 230 does not need to be too long. This makes it easier for maintenance personnel to disengage the first hook stop 131 from the connecting hook 230 of the frame 200 by pressing down on the seat 100 during the disassembly process.

[0055] refer to Figure 8 In some embodiments, in the longitudinal direction of the vehicle, the distance A2 between the lower end of the first segment 231 of the connecting hook 230 and the first hook stop 131 is greater than or equal to 7.5 mm and less than or equal to 9.5 mm. For example, in the longitudinal direction of the vehicle, the distance A2 between the lower end of the first segment 231 of the connecting hook 230 and the first hook stop 131 is 8.5 mm. This allows for sufficient distance between the first hook stop 131 of the second connector 130 and the lower end of the first segment 231, facilitating the placement of the first hook stop 131 of the second connector 130 within the limiting area 230a of the connecting hook 230.

[0056] refer to Figure 8 In some embodiments, the inclination angle A3 of the first segment 231 of the connecting hook 230 relative to the horizontal plane is greater than or equal to 55 degrees and less than or equal to 65 degrees. For example, the inclination angle A3 of the first segment 231 of the connecting hook 230 relative to the horizontal plane is 60 degrees. This allows the first segment 231 of the connecting hook 230 to have a better guiding effect during the installation of the seat cushion 100, thereby facilitating the guidance of the first hook stop 131 of the second connector 130 through the opening 230b of the connecting hook 230, and subsequently accommodated in the limiting area 230a of the connecting hook 230.

[0057] refer to Figure 8In some embodiments, the second segment 232 of the connecting hook 230 extends horizontally. In the vehicle's height direction, the distance A4 between the second segment 232 of the connecting hook 230 and the first hook stop 131 is greater than or equal to 10 mm and less than or equal to 13 mm. For example, in the vehicle's height direction, the distance A4 between the second segment 232 of the connecting hook 230 and the first hook stop 131 is 11.5 mm. This prevents scratching between the second segment 232 of the connecting hook 230 and the first hook stop 131 when the seat 100 is connected to the frame 200.

[0058] refer to Figure 8 In some embodiments, the height A5 of the opening 230b of the connecting hook 230 is greater than or equal to 14 mm and less than or equal to 17 mm. For example, the height A5 of the opening 230b of the connecting hook 230 is 15 mm. This makes the height of the opening 230b of the connecting hook 230 more suitable, thereby facilitating the smooth passage of the first hook stop 131 through the opening 230b of the connecting hook 230 during the assembly and disassembly of the seat cushion 100.

[0059] refer to Figure 8 In some embodiments, the connecting hook 230 further includes a fourth segment 234 connected to the third segment 233. The third segment 233 is indirectly connected to the second body 210 via the fourth segment 234. The fourth segment 234 extends forward relative to the third segment 233, and the region of the connecting hook 230 below the first segment 231 and above the fourth segment 234 forms an opening 230b. Exemplarily, the height of the opening 230b of the connecting hook 230 is the vertical distance between the bottom point of the first segment 231 and the apex of the fourth segment 234.

[0060] In some embodiments, the connecting hook 230 is formed from metal wire through a bending process. When the connecting hook 230 includes a fourth segment 234, the fourth segment 234 can be connected to the second body 210 of the frame 200. Exemplarily, the fourth segment 234 can be welded to the second body 210 of the frame 200 or connected via threaded fasteners. When the connecting hook 230 does not include a fourth segment 234, exemplarily, the side of the third segment 233 of the connecting hook 230 facing away from the second segment 232 can be directly connected to the second body 210 of the frame 200.

[0061] For example, the cross-section of the connecting hook 230 is circular. The diameter of the cross-section of the connecting hook 230 is greater than or equal to 6 mm and less than or equal to 10 mm. For example, the diameter of the cross-section of the connecting hook 230 is 8 mm. Of course, those skilled in the art can flexibly set the diameter of the cross-section of the connecting hook 230 according to actual needs when implementing the solution provided in the embodiments of this application, which will not be elaborated here.

[0062] To facilitate understanding of the solutions provided in the embodiments of this application by those skilled in the art, a more detailed connection scheme between the seat cushion 100 and the frame 200 is provided below for reference.

[0063] In some embodiments, the first body 110 of the cushion 100 includes a rigid frame, a flexible support member, and a covering member. Exemplarily, the rigid frame is made of steel. The flexible support member is made of a flexible material such as sponge. The covering member may be made of fabric or leather.

[0064] There are two first connectors 120 and two second connectors 130. The first connector 120 is formed by bending metal wire. The first connector 120 is U-shaped. The end of the first connector 120 facing the first body 110 can be welded to the rigid frame of the first body 110. The second connector 130 is formed by bending metal wire. The second connector 130 is U-shaped. For example, the diameter of the cross-section of both the first connector 120 and the second connector 130 is 5 mm.

[0065] The end of the second connector 130 facing the first body 110 can be welded to the rigid frame of the first body 110. Two first connectors 120 are spaced apart along the left-right direction of the vehicle, and two second connectors 130 are also spaced apart along the left-right direction of the vehicle. The two first connectors 120 are located on the front side of the seat cushion 100, and the two second connectors 130 are located on the rear side of the seat cushion 100.

[0066] The frame 200 includes a second body 210, a snap-fit ​​seat 220, and a connecting hook 230. The second body 210 of the frame 200 is formed from sheet metal using a stamping process. The snap-fit ​​seat 220 includes a telescopic piece 221, a sleeve, and an elastic element. The telescopic piece 221 is slidably connected to the sleeve, and the telescopic piece 221 is elastically connected to the sleeve via the elastic element. Thus, the elastic element can apply an elastic force to the telescopic piece 221, causing it to extend. The sleeve is connected to the second body 210. The fourth segment 234 of the connecting hook 230 is welded to the second body 210. Exemplarily, the diameter of the cross-section of the connecting hook 230 is 8 mm.

[0067] There are two snap-fit ​​seats 220 and two connecting hooks 230. The two snap-fit ​​seats 220 are spaced apart along the left and right directions of the vehicle, and the two connecting hooks 230 are also spaced apart along the left and right directions of the vehicle. The two snap-fit ​​seats 220 are located in front of the two connecting hooks 230. The first connecting member 120 is used to connect to the snap-fit ​​seat 220 in a one-to-one correspondence, and the second connecting member 130 is used to connect to the connecting hook 230 in a one-to-one correspondence.

[0068] During the installation of the seat cushion 100, the seat cushion 100 can be placed in the installation position first. When the seat cushion 100 is in the installation position, the first connector 120 is located above the snap-fit ​​seat 220, and the second connector 130 is located in front of the first section 231 of the connecting hook 230.

[0069] Furthermore, the first connector 120 can be connected to the snap-fit ​​seat 220 by pressing the portion of the seat 100 located above the first connector 120.

[0070] Furthermore, by pushing the seat cushion 100 from front to back, the second connector 130 can slide diagonally downward under the guidance of the first segment 231 of the connecting hook 230. This allows the second connector 130 to pass through the opening 230b and enter the limiting area 230a, thereby connecting the second connector 130 with the connecting hook 230.

[0071] For example, during the removal of the seat cushion 100, the second connector 130 can be disengaged from the limiting area 230a, pass through the opening 230b, and detach from the connector 230 by pressing the portion of the seat cushion 100 above the connecting hook 230 and pushing the seat cushion 100 from back to front.

[0072] Furthermore, the first connector 120 can be disengaged from the snap-fit ​​seat 220 by pulling on the area near the first connector 120 of the seat cushion 100. If the snap-fit ​​seat 220 has a latch, the latch can be released first, and then the first connector 120 can be disengaged from the snap-fit ​​seat 220 by pulling on the area near the first connector 120 of the seat cushion 100.

[0073] Thus, by adopting the solution provided in this application embodiment, the seat cushion 100 can be easily installed on the vehicle frame 200, and the seat cushion 100 can also be easily removed from the vehicle frame 200. Therefore, the assembly difficulty of the seat cushion 100 can be reduced, installation time can be saved, and the vehicle installation cost can be lowered. Furthermore, during later vehicle use, the seat cushion 100 also features easy disassembly and maintenance.
