Description

Technical Field

[0001] This application relates to an adjustment device, a seat, and an adjustment method thereof. Background Technology

[0002] As automotive products continue to evolve, car seat products are also being upgraded and improved. To enable drivers of different heights to drive comfortably or to provide passengers with a comfortable riding experience, existing car seat products, represented by zero-gravity seats, have flexible height and tilt angle adjustment functions, significantly improving comfort and adapting to the needs of drivers and passengers. However, the above-mentioned functional design also brings new technical problems, including but not limited to: the seat cannot quickly adjust its posture position in the event of a collision, and some posture positions are beyond the effective protection range of traditional safety components (such as airbags, seat belts, etc.).

[0003] In view of this, this application provides an adjustment device, a seat, and an adjustment method thereof, in order to at least partially solve the above-mentioned technical problems. Summary of the Invention

[0004] The purpose of this application is to provide an adjustment device.

[0005] Another objective of this application is to provide a seat.

[0006] Another objective of this application is to provide a method for adjusting a seat.

[0007] An adjustment device according to one aspect of this application includes: side plates, respectively disposed on both sides in the width direction, for providing mounting positions for a seat body; a base plate, respectively disposed on both sides in the width direction, for mounting and fixing the adjustment device; and an adjustment part, respectively disposed on both sides in the width direction, including: a first link and a second link; the first link is rotatably connected to the second link and rotatably connected to the front side of the base plate about a first axis; the second link is also rotatably connected to the front side of the side plate; wherein the adjustment part further includes: a third link, a drive assembly, and a locking assembly; the third link is rotatably connected to the first link about the first axis and rotatably connected to the drive assembly; the drive assembly is used to drive the third link and drive the first link and the second link to rotate, so that the side plate moves away from or closer to the base plate; the locking assembly is used to lock the relative rotation between the first link and the third link, and can be unlocked under collision conditions to allow the side plate to quickly move closer to the base plate.

[0008] It can be understood that, under normal operating conditions, the first link and the third link do not rotate relative to each other under the locking action of the locking assembly. That is, the third link can constrain the first link. The drive assembly drives the third link to rotate the first link and the second link, thereby causing the side plate to move away from or closer to the bottom plate, so as to realize the adjustment of the height and tilt angle of the seat body. When a collision occurs, the collision condition triggers the locking assembly to unlock the locking of the relative positional relationship between the first link and the third link. The constraint of the third link and the drive assembly on the first link is released, and the first link and the third link rotate relative to each other. The second link and the first link also rotate relative to each other, so that the side plate can quickly move closer to the bottom plate, that is, quickly drop to the lowest position. This design allows the seat to adjust quickly during the collision phase so that the occupant can enter a more ideal posture position and obtain effective protection from safety products (such as airbags, seat belts, etc.).

[0009] In one or more embodiments, the locking assembly includes a first pin and a propellant portion; the first pin is disposed in a locking position passing through the first link and the third link, for locking relative rotation of the first link and the third link; the propellant portion is used to drive the first pin out of the locking position.

[0010] In one or more embodiments, the adjusting device further includes a second connecting pipe and a third connecting pipe, wherein the second connecting pipe is connected between the third connecting rods along the width direction, and the third connecting pipe is connected between the second connecting rods along the width direction.

[0011] In one or more embodiments, the drive component is disposed only on one side along the width direction.

[0012] In one or more embodiments, the lock assembly is disposed only on one side along the width direction.

[0013] In one or more embodiments, the adjustment unit further includes an energy-absorbing component disposed between the first link and the third link, the energy-absorbing component being capable of absorbing energy when the first link and the third link rotate relative to each other.

[0014] In one or more embodiments, the energy-absorbing assembly includes a second pin, a groove, and a collapsible structure. The second pin is fixedly connected to the first connecting rod and passes through the groove. The collapsible structure is disposed on the lower side of the groove. When the first connecting rod and the third connecting rod rotate relative to each other, the second pin can slide along the groove and act on the collapsible structure.

[0015] In one or more embodiments, the drive assembly includes a motor, a lead screw and nut mechanism, and a drive rod.

[0016] According to another aspect of this application, a seat includes the adjustment device described in the above embodiments.

[0017] According to another aspect of this application, a seat adjustment method using the seat described in the above embodiments includes:

[0018] The seat receives a signal indicating whether a collision has occurred in the vehicle.

[0019] If no collision occurs, the seat is configured in a first state, and the locking assembly locks the relative rotation of the first link and the third link;

[0020] In the event of a collision, the seat is configured to a second state, and the locking assembly is unlocked. Attached Figure Description

[0046] Reference will now be made in detail to various embodiments of this application, examples of which are shown in the accompanying drawings and described below. Although this application will be described in conjunction with exemplary embodiments, it should be understood that this application is not intended to be limited to those exemplary embodiments. Rather, this application is intended to cover not only these exemplary embodiments, but also various alternatives, modifications, equivalents, and other embodiments that may be included within the spirit and scope of this application as defined by the appended claims.

[0047] This application uses specific terms to describe embodiments of the application. For example, "an embodiment" and / or "one embodiment" refers to a particular feature, structure, or characteristic associated with at least one embodiment of the application. Therefore, it should be emphasized and noted that "an embodiment" or "one embodiment" mentioned twice or more in different locations in this application does not necessarily refer to the same embodiment. Furthermore, certain features, structures, or characteristics in one or more embodiments of the application can be appropriately combined.

[0048] In the following description, the terms "upper," "lower," or other directional terms indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. These are used solely for the convenience of describing this application and for simplification, and do not indicate or imply that the device or component referred to must have a specific orientation, be constructed in a specific orientation, or be implemented in a specific orientation. Therefore, they should not be construed as limitations on this application. In this application, the terms "first," "second," etc., are used only for distinguishing descriptions and should not be construed as indicating or implying positional relationships or order of importance.

[0049] This application uses flowcharts to illustrate the operations performed according to embodiments of this application. It is understood that, depending on the actual situation, the steps shown in the diagrams may not necessarily be performed sequentially, and other operations may be added to these processes, or one or more steps may be removed from these processes.

[0050] It is understood that the technical solution of this application is particularly suitable for the rapid adjustment of car seat products, but is not limited thereto. It can also be applied to other applications, such as other means of transportation, such as railway trains, ships, etc.

[0051] In this application, the terms "length direction," "width direction," and "height direction" are determined according to the seat body, and respectively refer to the orientation (backward) of the seat, the extension direction of the sides of the seat, and the extension direction between the seat cushion and the backrest, that is, the x direction, y direction, and z direction shown in the figure; and in the length direction, it is divided into "front side" and "rear side" according to the orientation of the seat, that is, when the user sits on the seat, he faces the front direction and his back is to the rear direction; in the height direction, it is divided into "upper side" and "lower side"; in addition, the term "middle" used in this application does not represent the middle position in a strict sense, but refers to the position between one end and the other end.

[0052] As mentioned above, current automotive seat products already possess flexible and comprehensive posture adjustment functions, which places higher design requirements on safety performance. For example, there are issues such as some posture positions exceeding the effective protection range of existing safety components, and the inability to quickly adjust and reset after a collision. Based on this, the inventors of this application, after in-depth research, propose an adjustment device, a seat, and a vehicle.

[0053] refer to Figures 1 to 5 As shown, this application provides an adjustment device 10, which includes: side plates 11, respectively disposed on both sides in the width direction, for providing installation positions for the seat body; a base plate 12, respectively disposed on both sides in the width direction, for mounting and fixing the adjustment device 10; and an adjustment part 100, respectively disposed on both sides in the width direction, including: a first connecting rod 101 and a second connecting rod 102; the first connecting rod 101 is rotatably connected to the second connecting rod 102, and rotatably connected to the front side position of the base plate 12 around a first axis; the second connecting rod is also rotatably connected to the front side position of the side plate 11; wherein, the adjustment part 10... The adjustment device 10 also includes: a third link 103, a drive assembly 110, and a locking assembly 120; the third link 103 is rotatably connected to the first link 101 about the first axis and rotatably connected to the drive assembly 110; the drive assembly 110 is used to drive the third link 103 and drive the first link 101 and the second link 102 to rotate, so that the side plate 11 moves away from or closer to the base plate 12; the locking assembly 120 is used to lock the relative rotation between the first link 101 and the third link 103, and can be unlocked under collision conditions to allow the side plate 11 to quickly move closer to the base plate 12. Because the adjustment device 10 achieves the adjustment effect quickly, it can also be called a rapid adjustment device.

[0054] Specifically, the first connecting rod 101 is rotatably connected to the front of the base plate 12, and the second connecting rod 102 is rotatably connected to the front of the side plate 11, such that the side plate 11 is moved away from or closer to the base plate 12 mainly at the front of the seat. That is, the adjustment device 10 is used to provide height and tilt angle adjustment for the front of the seat. The seat body includes a seat cushion, a seat back, etc., and can also be a seat with an integrated seat belt (ABTS seat), etc. The seat body is fixedly connected to the side plate 11, and the base plate 12 installs and fixes the adjustment device 10 and the seat body in the application scenario, such as the floor of a car interior. Optionally, the adjustment device also includes a first connecting pipe 104, which is connected between the base plates 12 along the first axis and passes through the first connecting rod 101 and the third connecting rod 103. Optionally, the locking assembly can be unlocked by electric, pneumatic, or other driving methods, but is not limited thereto.

[0055] It can be understood that, under normal operating conditions, the first link 101 and the third link 103 do not rotate relative to each other under the locking action of the locking assembly 120. That is, the third link 103 can constrain the first link 101. The driving assembly 110 drives the third link 103 to rotate the first link 101 and the second link 102, thereby causing the side plate 11 to move away from or closer to the base plate 12, so as to realize the adjustment of the height and tilt angle of the seat body. When a collision occurs, the collision condition triggers the locking assembly 120 to unlock the first link 101 and the third link 103. The locking of the relative positional relationship between the first and second links releases the constraint of the third link 103 and the drive assembly 110 on the first link 101, allowing relative rotation between the first link 101 and the third link 103, and also relative rotation between the first link 101 and the second link 102. This allows the side plate 11 to quickly approach the bottom plate 12, i.e., quickly fall to the lowest position. By setting the first link 101 and the third link 103 to both be able to rotate around the first axis, it is possible to avoid the third link 103 still limiting the first link 101 after the locking assembly 120 is unlocked. The design of the adjustment device 10 allows the seat to quickly adjust to a more ideal posture position during a collision, thereby providing effective protection for the occupant from safety components (such as airbags, seat belts, etc.).

[0056] like Figure 4 , Figure 6A , Figure 6B As shown, in one or more embodiments, the locking assembly 120 includes a first pin 121 and a propellant section. The first pin 121 is disposed at a locking position passing through the first connecting rod 101 and the third connecting rod 103, for locking the relative rotation of the first connecting rod 101 and the third connecting rod 103. The propellant section may include propellant and a detonating device. When a collision occurs, the detonating device receives a signal to detonate the propellant and generate high-pressure gas, which drives the first pin 121 out of the locking position to unlock it. The propellant-driven mechanism provides structural and functional stability and reliability, and helps ensure the adjustment speed of the adjusting device 10.

[0057] In one or more embodiments, the locking assembly 120 further includes a spring 122, and the first pin 121 is provided with a step, one side of which abuts against the third link 103 or the first link 101, and the other side is pressed by the spring 122 to ensure that the first pin 121 can be held in the locked position under normal operating conditions.

[0058] like Figure 4 , Figure 5As shown, in one or more embodiments, the adjustment device 10 further includes a second connecting pipe 105 fixedly connected to the third connecting rod 103 along the width direction; a third connecting pipe 106 fixedly connected to the second connecting rod 102 along the width direction; and a fourth connecting pipe 107 fixedly connected to the side plates 11 along the width direction. This design helps to improve the structural strength of the adjustment device 10, maintain balanced deformation on both sides during a collision, withstand large-energy impacts, and ensure that the adjustment device 10 can generate synchronous adjustment activities on both sides in the width direction. In addition, the fourth connecting pipe 107 can also provide support for the seat body.

[0059] like Figure 4 , Figure 5 As shown, in one or more embodiments, the lock assembly 120 may be provided only on one side along the width direction; and, as Figure 5 As shown, the third link 103 and / or the first link 101 on the side without the locking assembly 120 do not provide a locking position for the locking assembly 120. This design helps ensure the stability and reliability of the unlocking function during a collision, reduces the risk of failure compared to a solution with the locking assembly 120 on both sides, and is more cost-effective.

[0060] In one or more embodiments, the drive component 110 may be provided only on one side along the width direction; this is more cost-effective than providing the drive component 110 on both sides.

[0061] like Figure 7A , 7B As shown, in normal operating conditions, the locking assembly 120 locks the relative rotation of the first connecting rod 101 and the third connecting rod 103. Under the drive of the driving unit 110, the third connecting rod 103 drives the first connecting rod 101 and the second connecting rod 102 to rotate, thereby allowing the side plate 11 to move closer to or further away from the base plate 12; Figure 8A , 8B As shown, when a collision occurs, the locking assembly 120 unlocks, and the constraint relationship between the first link 101 and the third link 103 is released. That is, the third link 103 no longer limits the first link 101. At this time, the first link 101 and the second link 102 can rotate rapidly under the action of gravity and collision impact, so that the side plate 11 quickly approaches the bottom plate 12, and the seat body can be adjusted from an undesirable posture position, such as zero gravity mode, to an ideal position to obtain effective safety protection.

[0062] like Figure 5As shown, in one or more embodiments, the adjustment unit 100 further includes an energy-absorbing component 130, which is disposed between the first connecting rod 101 and the third connecting rod 103. The energy-absorbing component 130 is capable of absorbing energy when the first connecting rod 101 and the third connecting rod 103 rotate relative to each other. Specifically, the energy-absorbing component may include a second pin 131 and a collapsible structure 133. The collapsible structure 133 is disposed on the third connecting rod 103. The second pin 131 is fixedly connected to the first connecting rod 101 and passes through the upper side of the collapsible structure 133 on the third connecting rod 103. When the first connecting rod 101 and the third connecting rod 103 rotate relative to each other, the second pin 131 impacts the collapsible structure 133, causing it to deform and break, thereby absorbing impact energy. The use of the energy-absorbing component 130 further enhances the safety of the seat.

[0063] In one or more embodiments, the energy-absorbing component 130 further includes a groove 132 disposed in the third link 103, the second pin 131 being able to slide in the groove 132, and the collapsible structure 133 being disposed on the lower side of the groove 132; under normal operating conditions, the second pin 131 may be disposed at the upper end of the groove 132; after the locking component 120 is unlocked, the second pin 131 can slide along the groove 132. This design helps to ensure the impact direction of the second pin 131 on the collapsible structure 133 during a collision, improving the energy absorption effect, and also helps to limit the relative rotation of the first link 101 and the third link 103, further improving the stability of the adjusting device 10.

[0064] like Figure 3 As shown, in one or more embodiments, the drive assembly 110 includes a motor 111, a lead screw and nut mechanism 112, and a drive rod 113. Specifically, the motor 111 drives the lead screw of the lead screw and nut mechanism 112 to rotate, and the nut of the lead screw and nut mechanism 112 converts the rotational motion into linear movement and drives the drive rod 113. The drive rod 113 is rotatably connected to the third connecting rod 103 to drive the third connecting rod 103 to rotate around the first axis. Compared with the design using a height adjustment pump, the design of the drive assembly 110 avoids the shaking and jumping problems caused by gear meshing in the height adjustment pump. The adjustment process is stable and does not produce a dead noise, improving the user's experience and comfort.

[0065] As described above, this application also provides a seat, which includes the adjustment device 10 described in the above embodiments.

[0066] In one or more embodiments, the seat is an ABTS (Integrated Seat Belt and Seat Belt) seat; this design, which fixes the seat belt retractor to the seat, is more conducive to providing a seat belt restraint effect that conforms to the human body posture at different seat heights and tilt angles, compared to the traditional solution of placing the seat belt retractor in other positions, thus providing more effective protection for the user.

[0067] like Figure 9 As shown above, this application also provides a seat adjustment method, using a seat as described in the above embodiments, comprising:

[0068] The seat receives a signal indicating whether a collision has occurred in the vehicle.

[0069] If no collision occurs, the seat is configured in a first state, and the locking assembly 120 locks the relative rotation of the first link 101 and the third link 103;

[0070] In the event of a collision, the seat is configured to a second state, and the locking assembly 120 is unlocked.

[0071] The first state is the normal operating state, and the second state is the state in response to a collision; specifically, the second state may also include the detonation device receiving a signal to detonate the gunpowder to generate high-pressure gas.

[0072] In summary, the beneficial effects of the solutions described in the above embodiments include, but are not limited to, the ability of the seat to quickly adjust to a more ideal posture position during a collision by adjusting the device, thereby providing occupants with effective protection from safety components (such as airbags, seat belts, etc.).

[0073] While this application discloses preferred embodiments as described above, it is not intended to limit the scope of this application. Any changes and modifications can be made by those skilled in the art without departing from the spirit and scope of this application. Therefore, any modifications, equivalent changes, and alterations made to the above embodiments based on the technical essence of this application, without departing from the content of the technical solution of this application, fall within the protection scope defined by the claims of this application.
