Description

Technical Field

[0001] This utility model relates to the field of seating technology, and in particular to a split-type seat intermediate support mechanism and seat. Background Technology

[0002] To facilitate folding and storage of seats and flexibly adjust interior space, seats are typically designed as separate units with a certain division ratio. One side of the seat connects to the vehicle body, while adjacent seats are connected by a central support mechanism. To accommodate the hip point (H-point) height of the car seat, the seat cushion usually needs to be raised. Consequently, the central support mechanism will also be significantly higher than the vehicle floor. This results in the central support mechanism still being higher than the vehicle floor even after the seat is folded down, affecting the usability and aesthetics of the vehicle's luggage compartment. Utility Model Content

[0003] The purpose of this utility model is to provide a split-type seat middle support mechanism and seat, so that when the seat is folded into the pit, the middle support mechanism is hidden so that it does not protrude from the vehicle floor, which facilitates the use of the luggage compartment and does not affect the aesthetics.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] This utility model provides a split-type seat middle support mechanism, which has a height direction and includes:

[0006] The mounting bracket has a first limiting part;

[0007] The connecting assembly includes a first connector and a second connector that are rotatably connected. The end of the first connector away from the second connector is rotatably connected to the mounting bracket. The end of the first connector near the second connector has a second limiting portion.

[0008] Connecting bracket, used for connecting to the seat body; and

[0009] The first rotating shaft has one end connected to the second connecting piece and the other end rotatably connected to the connecting bracket.

[0010] The connecting component has a first position and a second position. In the first position, the first connector abuts against the first limiting portion, and the second connector abuts against the second limiting portion, so that the connecting component is supported between the mounting bracket and the connecting bracket. In the second position, the second connector is folded over the first connector, and in the height direction, the connecting bracket protrudes from the connecting component.

[0011] In some embodiments, the second connector has a clearance groove that extends through the second connector along its length; the first connector is at least partially inserted into the clearance groove.

[0012] In some embodiments, the end of the second connector away from the first connector is provided with an avoidance notch.

[0013] In some embodiments, the system further includes a fixing member and a pull cable. The fixing member is connected to the second connector, one end of the pull cable is connected to the fixing member, and the other end of the pull cable is used to connect to the ground lock unlocking motor.

[0014] In some embodiments, it also includes:

[0015] The second rotating shaft is connected to the mounting bracket, and the end of the first connecting member away from the second connecting member is rotatably sleeved on the second rotating shaft;

[0016] An elastic element is connected to the second rotating shaft. The elastic element has a first working arm and a second working arm. The first working arm abuts against the first connecting member, and the second working arm is connected to the mounting bracket.

[0017] In some embodiments, a third rotating shaft is further included, and the first connecting member and the second connecting member are respectively sleeved on the third rotating shaft.

[0018] In some embodiments, the ends of the first rotating shaft, the second rotating shaft, and the third rotating shaft are all provided with stop members.

[0019] In some embodiments, the mounting bracket includes:

[0022] The first connecting arm and the second connecting arm are respectively connected to both sides of the limiting plate in the width direction, and the first connecting arm and the second connecting arm extend out of the limiting plate in the length direction, and the first connecting member is rotatably connected between the first connecting arm and the second connecting arm.

[0023] In some embodiments, bushings are provided on the connecting bracket, the first connector, and the second connector.

[0024] This utility model also provides a seat, including a seat body and a split-type seat intermediate support mechanism as described above.

[0025] Compared with the prior art, the advantages of this utility model embodiment of a split-type seat intermediate support mechanism and seat are as follows:

[0026] This utility model's split-type seat intermediate support mechanism includes a connecting component between a mounting bracket and a connecting bracket. The connecting component includes a first connecting member and a second connecting member that are rotatably connected. The connecting component has a first position and a second position. In the first position, the first connecting member abuts against a first limiting part, and the second connecting member abuts against a second limiting part, so that the connecting component is supported between the mounting bracket and the connecting bracket, corresponding to the seat's seating position. Connecting the first connecting member and the second connecting member forms the connecting component, giving it a certain length in the first position. This connecting component increases the height of the seat connected to the connecting bracket, allowing it to meet the seat's H-point height requirement. In the second position, the second connecting member is folded over the first connecting member, and the connecting bracket protrudes from the connecting component in the height direction, corresponding to the seat's retracted position. This ensures that when the seat is retracted, the connecting component does not protrude from the seat in the height direction, thus concealing the intermediate support mechanism and preventing the connecting component from being higher than the vehicle floor when the seat is retracted, which would affect the usability and aesthetics of the vehicle's luggage compartment.

[0040] In the description of this utility model, it should be noted that the terms "center," "upper," "lower," "front," "rear," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the accompanying drawings and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0041] In the description of this utility model, it should be noted that, unless otherwise explicitly 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 mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0042] The specific embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate this utility model, but are not intended to limit its scope.

[0043] See Figures 1-10 As shown, this embodiment of the utility model provides a split-type seat middle support mechanism, which has a height direction, and the height direction is... Figure 10 The direction indicated by the middle arrow. The split-type seat center support mechanism includes a mounting bracket 10, a connecting assembly 20, a connecting bracket 30, and a first rotating shaft 40. The mounting bracket 10 has a first limiting portion 101 and is used to connect to the vehicle body. The connecting assembly 20 includes a first connecting member 21 and a second connecting member 22 that are rotatably connected. The end of the first connecting member 21 away from the second connecting member 22 is rotatably connected to the mounting bracket 10, and the end of the first connecting member 21 near the second connecting member 22 has a second limiting portion 211. The connecting bracket 30 is used to connect to the seat body 100. One end of the first rotating shaft 40 is connected to the second connecting member 22, and the other end of the first rotating shaft 40 is rotatably connected to the connecting bracket 30, allowing the connecting bracket 30 to rotate around the first rotating shaft 40. The first rotating shaft 40 and the second connecting member 22 can be welded together.

[0044] See Figure 8 and Figure 10 As shown, the connecting assembly 20 has a first position and a second position. In the first position, the first connecting member 21 abuts against the first limiting part 101, and the second connecting member 22 abuts against the second limiting part 211, so that the connecting assembly 20 is supported between the mounting bracket 10 and the connecting bracket 30. The first limiting part 101 limits the maximum forward rotation of the first connecting member 21, and the second limiting part 211 limits the maximum forward rotation of the second connecting member 22. Here, "forward" refers to the direction facing the front of the vehicle when the intermediate support mechanism is installed inside the vehicle. The first limiting part 101 and the second limiting part 211 stabilize the connecting assembly 20 in the first position. In the second position, the second connecting member 22 is folded over the first connecting member 21, and in the height direction, the connecting bracket 30 protrudes from the connecting assembly 20.

[0045] The first position of the connecting component 20 corresponds to the seat's seated position. The first connector 21 and the second connector 22 are connected to form the connecting component 20, which is supported between the mounting bracket 10 and the connecting bracket 30, so that the connecting component 20 has a certain length in the first position. The connecting component 20 can increase the height of the seat connected to the connecting bracket 30 to meet the seat's H-point height requirement. The second position of the connecting component 20 corresponds to the seat's folded-in position. The second connector 22 is folded over the first connector 21, and the connecting bracket 30 protrudes from the connecting component 20 in the height direction. This ensures that when the seat is folded in, the connecting component 20 does not protrude from the seat in the height direction, thus hiding the intermediate support mechanism and preventing the connecting component 20 from being higher than the vehicle floor 300 when the seat is folded in, which would affect the use and aesthetics of the vehicle's luggage compartment.

[0046] See Figure 3 As shown, in some embodiments, the mounting bracket 10 includes a bracket body 11, a limiting plate 12, a first connecting arm 13, and a second connecting arm 14. The bracket body 11 is used to connect to the vehicle body and is connected to the vehicle body by bolts. The limiting plate 12 is connected to the bracket body 11 to form a first limiting portion 101. The first connecting arm 13 and the second connecting arm 14 are respectively connected to both sides of the limiting plate 12 in the width direction, and the first connecting arm 13 and the second connecting arm 14 extend out of the limiting plate 12 in the length direction. The first connecting member 21 is rotatably connected between the first connecting arm 13 and the second connecting arm 14. This arrangement facilitates the first connecting member 21 abutting against the limiting plate 12 when the connecting assembly 20 is in the first position; it also ensures that the space between the first connecting arm 13 and the second connecting arm 14 provides sufficient space for the rotation of the first connecting member 21 when it rotates relative to the mounting bracket 10. In some embodiments, the first connecting arm 13, the second connecting arm 14, and the limiting plate 12 are integrally formed with the bracket body 11. The first connecting arm 13 and the second connecting arm 14 are also connected to both sides of the support body 11 in the width direction, so that the first connecting arm 13, the second connecting arm 14 and the support body 11 are connected in a U-shaped structure, which facilitates the accommodation of part of the first connecting member 21 when the first connecting member 21 rotates.

[0047] See Figure 1 and Figure 2 As shown, in some embodiments, the split-type seat intermediate support mechanism further includes a second rotating shaft 60, which is connected to the mounting bracket 10. The end of the first connecting member 21 away from the second connecting member 22 is rotatably sleeved on the second rotating shaft 60. The first connecting member 21 is connected to the mounting bracket 10 via the second rotating shaft 60, and the first connecting member 21 rotates relative to the mounting bracket 10 about the second rotating shaft 60. The rotation center axis of the second rotating shaft 60 is parallel to the rotation center axis of the first rotating shaft 40.

[0048] See Figures 1-3 As shown, in some embodiments, the split-type seat intermediate support mechanism further includes an elastic element 70, which is connected to the second rotating shaft 60. The elastic element 70 has a first acting arm 701 and a second acting arm 702. The first acting arm 701 abuts against the first connecting member 21, and the second acting arm 702 is connected to the mounting bracket 10. The elastic element 70 stores elastic potential energy to provide a force for the rotational reset of the first connecting member 21. The mounting bracket 10 has a socket 141, and the second acting arm 702 is inserted into the socket 141. The socket 141 can be located on the second connecting arm 14 of the mounting bracket 10. The elastic element 70 is a spring.

[0049] See Figure 5 As shown, in some embodiments, the second connector 22 has a clearance groove 221 that extends through the second connector 22 along its length; the first connector 21 is at least partially inserted into the clearance groove 221. By providing the clearance groove 221, the second connector 22 is easily accommodated when folded over the first connector 21, reducing the overall space occupied by the connecting assembly 20. The first connector 21 has a first surface 212 and a second surface 213 disposed opposite to each other, with a second limiting portion 211 formed at the end of the first surface 212 near the second connector 22. In the first position, the first surface 212 abuts against the first limiting portion 101, and the second connector 22 abuts against the first surface 212. In the second position, the bottom surface of the clearance groove 221 of the second connector 22 is close to the second surface 213, so that the first connector 21 is placed within the clearance groove 221. The second connector 22 has a clearance notch 222 at the end away from the first connector 21 to prevent the second connector 22 from interfering with the rotation of the first connector 21 relative to the mounting bracket 10 when it is folded onto the first connector 21. (See reference...) Figure 4 As shown, in some embodiments, the first connector 21 is a groove structure, the top surface of the groove wall of the first connector 21 is the first surface 212, and the outer wall surface of the groove bottom of the first connector 21 is the second surface 213.

[0050] See Figure 2 and Figure 7As shown, in some embodiments, the split-type seat middle support mechanism further includes a fixing member 50 and a pull cable 51. The fixing member 50 is connected to the second connecting member 22, one end of the pull cable 51 is connected to the fixing member 50, and the other end of the pull cable 51 is used to connect to the floor lock unlocking motor 200. By retracting the pull cable 51 through the floor lock unlocking motor 200, the second connecting member 22 is driven to rotate relative to the first connecting member 21 and fold onto the first connecting member 21. Using the floor lock unlocking motor 200 to provide driving force for the folding of the second connecting member 22, and the second connecting member 22 and the floor lock 400 using the same actuator motor, the use of a power source can be reduced, and the layout can be simplified.

[0051] See Figure 1 and Figure 2 As shown, in some embodiments, the split-type seat intermediate support mechanism further includes a third rotating shaft 80, with the first connecting member 21 and the second connecting member 22 respectively sleeved on the third rotating shaft 80. The third rotating shaft 80 connects the first connecting member 21 and the second connecting member 22, allowing the first connecting member 21 and the second connecting member 22 to rotate relative to each other. The rotation center axis of the third rotating shaft 80 is parallel to the rotation center axis of the first rotating shaft 40.

[0052] See Figure 1 and Figure 2 As shown, in some embodiments, the ends of the first rotating shaft 40, the second rotating shaft 60, and the third rotating shaft 80 are all provided with stoppers 41 to prevent axial movement of each rotating shaft. The stopper 41 can be a component independent of the rotating shaft, such as a retaining ring or a nut 411. The stopper 41 can also be a flange integral with the rotating shaft. Optionally, see [reference needed]. Figure 1 and Figure 2 As shown, the first rotating shaft 40 is rotatably inserted into the connecting bracket 30, with one end extending into the connecting bracket 30. A nut 411 is threaded onto the end of the first rotating shaft 40 extending into the connecting bracket 30. A flange is provided at the end of the first rotating shaft 40 that connects to the second connecting member 22. A flange is provided at one end of the second rotating shaft 60, and a retaining ring is provided at the other end. A flange is provided at one end of the third rotating shaft 80, and a retaining ring is provided at the other end.

[0053] See Figure 1 and Figure 2As shown, in some embodiments, bushings 90 are provided on the connecting bracket 30, the first connecting member 21, and the second connecting member 22. The bushings 90 serve a lubricating function. The bushings 90 are fixedly connected to the connecting bracket 30, the first connecting member 21, and the second connecting member 22, for example, by riveting. When the connecting bracket 30 is connected to the first rotating shaft 40, the bushing 90 connected to the connecting bracket 30 is fitted onto the first rotating shaft 40. When the first connecting member 21 is connected to the mounting bracket 10 via the second rotating shaft 60, the bushing 90 connected to the first connecting member 21 is fitted onto the second rotating shaft 60. When the second connecting member 22 is connected to the first connecting member 21 via the third rotating shaft 80, the bushing 90 connected to the second connecting member 22 is fitted onto the third rotating shaft 80.

[0054] See Figure 6 and Figure 7 As shown, this utility model also provides a seat, including a seat body 100 and the aforementioned split-type seat intermediate support mechanism. The split-type seat intermediate support mechanism is connected to one side of the seat body 100. The other side of the seat body 100 is usually connected to a flip-up assist mechanism 500, which provides assistance for flipping the seat body 100. This utility model will not be described in detail.

[0055] The working process of this utility model is as follows:

[0056] See Figure 6 and Figure 8 As shown, when the seat is in the sitting position, the floor lock 400 is locked to the vehicle floor 300, and the connecting component 20 is in the first position. At this time, the first connecting member 21 abuts against the first limiting part 101, and the second connecting member 22 abuts against the second limiting part 211. The first connecting member 21 and the second connecting member 22 are connected to each other and supported between the mounting bracket 10 and the connecting bracket 30 to support the seat body 100.

[0057] When changing the seat from the sitting position to the storage position, unlock the floor lock 400, flip the seat body 100, and the seat body 100 will cause the connecting bracket 30 and the second connecting piece 22 to rotate synchronously relative to the first connecting piece 21 until the seat is fully retracted into the recess. At this point, refer to... Figure 9 As shown, the second connector 22 is folded over the first connector 21, and in the height direction, the connecting component 20 protrudes from the connecting bracket 30. Then, by retracting the pull cable 51 through the ground lock unlocking motor 200, the pull cable 51 pulls the second connector 22. Since the second connector 22 is folded over the first connector 21, when the pull cable 51 pulls the second connector 22 to rotate relative to the first rotating shaft 40, the second connector 22 drives the first connector 21 to rotate synchronously. The first connector 21 rotates around the second rotating shaft 60 until, in the height direction, the connecting bracket 30 protrudes from the connecting component 20. At this time, the connecting component 20 switches to the second position. See reference. Figure 10As shown, the intermediate support mechanism is hidden within the seat.

[0058] In summary, this utility model embodiment provides a split-type seat intermediate support mechanism and seat, which not only meets the seat's H-point height requirement, but also ensures that the connecting component 20 does not protrude from the seat in the height direction when the seat is folded into the recess, thus concealing the intermediate support mechanism. This prevents the connecting component 20 from being higher than the vehicle floor 300 when the seat is folded into the recess, which would affect the use and aesthetics of the vehicle's luggage compartment.

[0059] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and substitutions can be made without departing from the technical principles of the present utility model, and these improvements and substitutions should also be considered within the protection scope of the present utility model.
