Description

Technical Field

[0001] This invention relates to the field of automotive seat technology, specifically to a deformable seat support system and an automotive seat. Background Technology

[0002] As we all know, a child safety seat is a car safety accessory specifically designed for children. In the event of a car collision or sudden deceleration, a child seat can reduce the impact force on the child and restrict the child's body movement, thereby mitigating the injury.

[0003] Currently, child seats, as an essential accessory for car seats, are not utilized very frequently. When children are not in the car, they take up interior space and affect the comfort of adult passengers in the back. On the other hand, child seats are expensive to purchase, and their low utilization rate undoubtedly represents a waste of resources and money. Summary of the Invention

[0004] In view of this, one of the objectives of the present invention is to provide a deformable seat support system that aims to solve the aforementioned technical problems of attached child seats.

[0005] To achieve the above objectives, the technical solution of the present invention is as follows:

[0006] A deformable seat support system, the key feature of which is that it includes:

[0007] Base;

[0008] A support assembly disposed above the base, the support assembly including a first support plate and a second support plate located at the front end of the first support plate; and

[0009] A transmission mechanism is installed between the support assembly and the base. This transmission mechanism is used to drive the first support plate to move up and down, and to drive the second support plate to move over. When the first support plate moves up, the second support plate flips down at the front end of the first support plate.

[0010] Preferably, the transmission mechanism includes a drive device mounted on the base, a four-bar linkage between the second support plate and the first support plate, and a fork lifting linkage between the first support plate and the base. The drive device drives the four-bar linkage to move so that the flipping motion of the second support plate and the lifting motion of the first support plate are executed synchronously.

[0011] Preferably, the fork lifting link includes a first link and a second link hinged to the middle of the first link. One end of the first link is hinged to a first support plate, and the other end is rotatably connected to a guide component, which is slidably mounted on the base. The end of the second link away from the first link is hinged to the base.

[0012] Preferably, the first support plate has a bent portion at its front end, and the four-bar linkage includes a first linkage component, a second linkage component, the bent portion, and the second support plate that are rotatably connected in sequence.

[0013] Preferably, the driving device is a lead screw motor, which includes a lead screw that rotates relative to the base, one end of the second linkage component is slidably mounted on the base, and the second linkage component is provided with a nut sleeve threaded onto the lead screw.

[0014] Preferably, the second linkage component is a plate structure, with a retaining link located between the middle of its lower end and the middle of the lower end of the second support plate.

[0015] Preferably, the base is provided with a guide groove, and the guide component is a rod-shaped structure that is slidably disposed on the guide groove.

[0016] Preferably, the base is equipped with an actuator that drives the guide component to slide back and forth.

[0017] Preferably, the transmission mechanism has two power units, one of which is used to drive the first support plate to move up and down, and the other is used to drive the second support plate to move over.

[0018] The second objective of this invention is to provide an automobile seat, the key feature of which is that the automobile seat includes the seat support system provided by the first objective of the invention.

[0019] The beneficial effects of this invention are:

[0020] 1. The seat support system can switch from adult seat mode to child seat mode, which greatly improves the utilization rate of the seat and is of great significance for improving the utilization rate of the vehicle interior space and reducing the cost of vehicle use.

[0021] 2. When the child seat is in its tilted position, the second support plate can support the child's lower legs, ensuring the child's comfort.

[0022] 3. The deformable structure design of the seat support system is simple and ingenious, with technical advantages such as low cost and ease of implementation.

[0023] 4. Using the bent part of the first support plate as a component of the four-bar linkage can avoid dead points in the retracted state, making it more feasible. Attached Figure Description

[0025] Figure 2This is a first side view of the seat support system (transformed into a child seat configuration);

[0026] Figure 3 This is a second side view of the seat support system (transformed into an adult seat position). Detailed Implementation

[0027] The present invention will be further described below with reference to the embodiments and accompanying drawings.

[0028] Example 1

[0029] like Figure 1 and 2 As shown, a seat support system includes a base 1, a support assembly 2, and a transmission mechanism. The base 1 is used for fixed installation on a seat frame, or the base 1 is part of the seat frame. The support assembly 2 consists of a second support plate 2b and a first support plate 2a distributed front to back. The transmission mechanism is disposed between the support assembly 2 and the base 1, and the transmission mechanism enables the support assembly 2 to switch between an adult seat position and a child seat position.

[0030] like Figure 3 As shown, in the adult seat position, the first support plate 2a is mainly used to support the adult's buttocks, and the second support plate 2b is mainly used to support the adult's thighs.

[0031] like Figure 2 As shown, in the child seat position, the first support plate 2a is mainly used to support the child's buttocks and thighs, and the second support plate 2b is mainly used to support the child's calves.

[0032] Please see Figure 2 In this embodiment, the transmission mechanism consists of a drive device A, a four-bar linkage B, and a fork lifting linkage C, specifically:

[0033] The four-bar linkage B is positioned between the second support plate 2b and the first support plate 2a, and is composed of... Figure 2 It can be seen that the front end of the first support plate 2a is inclined and has a bent part 2a1. The four-bar linkage B is composed of the first linkage component 3e, the second linkage component 3f, the bent part 2a1 and the second support plate 2b, which are rotated and hinged in sequence.

[0034] Then by Figure 1 It can be seen that the fork lifting link C includes a first link 3b and a second link 3c hinged to the middle of the first link 3b. The upper end of the first link 3b is hinged to the rear end of the first support plate 2a, and the lower end is rotatably connected to a guide component 3a. The guide component 3a is slidably mounted on the base 1. The end of the second link 3c away from the first link 3b is hinged to the rear end of the base 1.

[0035] The drive device A is a lead screw motor, which includes a lead screw 3g that rotates relative to the base 1. The lower end of the second linkage component 3f is slidably mounted on the base 1. The second linkage component 3f is provided with a nut sleeve 3f1 that is threaded onto the lead screw 3g.

[0036] Based on the above-described transmission mechanism, the working principle of the seat support system in changing from an adult seat state to a child seat state is as follows: the drive device A drives the lower end of the second linkage component 3f to move backward. Under the action of the four-bar linkage B, the second support plate 2b flips downward relative to the front end of the first support plate 2a. This process will drive the first support plate 2a to move forward. Then, under the coordinated action of the fork lifting linkage C, the first support plate 2a can be raised.

[0037] The transmission mechanism in the above-described embodiment uses a set of power sources, namely drive device A, to achieve synchronous control of the flipping motion of the second support plate 2b and the lifting motion of the first support plate 2a, which has technical advantages such as simple structure and ease of implementation. In addition to the above-described embodiment, the transmission mechanism can also employ two sets of power devices, with the two sets of power devices respectively controlling the lifting motion of the first support plate 2a and the flipping motion of the second support plate 2b.

[0038] In this embodiment, the second linkage component 3f is a plate structure, and two sets of retaining rods 3h are provided between the middle of its lower end and the middle of the lower end of the second support plate 2b. This design can ensure the stability of the second support plate 2b installation and improve the comfort of the seat.

[0039] For example Figure 1 As shown, the base 1 has a guide groove 1a at its rear, and the guide component 3a is a rod-shaped structure that is slidably mounted on the guide groove 1a. The base 1 is also equipped with an actuator 4, which drives the guide component 3a to slide back and forth. The actuator 4, operating independently, can adjust the height of the rear end of the first support plate 2a, thereby achieving the tilt angle adjustment of the seat.

[0041] An automobile seat includes the seat support system described in Embodiment 1, wherein the base 1 of the seat support system is detachably mounted on the seat frame, or the base 1 is integrally formed with the seat frame.

[0042] Finally, it should be noted that the above description is merely a preferred embodiment of the present invention. Those skilled in the art, under the guidance of the present invention, can make various similar representations without departing from the spirit and claims of the present invention, and such modifications all fall within the protection scope of the present invention.
