Description

Technical Field

[0001] This disclosure relates to the field of automotive seat manufacturing technology, and in particular to an electric seat structure and an automotive seat. Background Technology

[0002] Car seats have always been one of the most important components of a car. Installed inside the vehicle, seats provide support and protection for occupants. With technological advancements and improved living standards, consumers are placing higher demands on the comfort and practicality of seats. In particular, when sitting in a car, the lower legs are often in a bent position for extended periods, leading to soreness. As a result, car seats with leg rests have appeared on the market. The leg rest structure allows for adjustments in seat cushion length to accommodate occupants of different body types and needs, enhancing seating comfort and gaining popularity among consumers. Examples include existing patents CN210941460U and CN111483376A.

[0003] However, when adjusting the leg rest angle, some car seats may have exposed swing structures when viewed from the side, affecting the overall appearance of the car seat and making it difficult to raise or lower the leg rest. Utility Model Content

[0004] The purpose of this disclosure is to overcome the shortcomings of the prior art and provide an electric seat structure and car seat that can block the swing structure, so that the swing structure is always blocked during the lifting or lowering process.

[0005] The purpose of this disclosure is achieved through the following technical solution:

[0006] An electric seat structure includes a seat base, a leg rest, two armrests, two elastic fabrics, and a leg rest lifting mechanism. The seat base has a base contact surface, and the leg rest is connected to the base contact surface. The two armrests are respectively connected to opposite sides of the seat base. One side of each elastic fabric is connected to the side of the seat base adjacent to the armrest, and the other side of each elastic fabric is connected to the leg rest. The leg rest lifting mechanism is used to connect to an external power source. The lifting and rotation output end of the leg rest lifting mechanism is connected to the leg rest, and the leg rest lifts and rotates around the connection point with the base contact surface to form a preset angle between the leg rest and the base contact surface.

[0007] In one embodiment, a connecting gap is formed between the seat base and the seat armrest, and a portion of the elastic fabric structure is located within the connecting gap.

[0008] In one embodiment, the leg support lifting mechanism includes a drive motor and a lifting bracket. The drive motor is connected to an external power source, and the control output terminal of the drive motor is connected to one end of the lifting bracket, while the other end of the lifting bracket is connected to the seat leg support.

[0009] In one embodiment, the lifting bracket includes a first bracket, a rotating joint, and a second bracket. The first bracket is movably connected to the second bracket via the rotating joint. The first bracket is connected to the control output terminal of the drive motor, and the second bracket is also fixedly connected to the seat leg rest.

[0010] In one embodiment, the preset angle range is 90-150°.

[0011] In one embodiment, the thickness of the elastic fabric is 3mm-3.5mm.

[0012] In one embodiment, the electric seat structure further includes a seat back, which is connected to the seat base.

[0013] In one embodiment, the angle formed by the seat back and the seat base is in the range of 100-115°.

[0014] An automobile seat includes the electric seat structure described in any of the above embodiments.

[0015] Compared with the prior art, this disclosure has at least the following advantages:

[0016] The aforementioned electric seat structure features an elastic fabric connected to the seat armrests and leg rests. When the leg rest lifting mechanism drives the leg rest to lift it to a certain angle, the leg rest stretches the elastic fabric, causing it to cover the lifting mechanism. From the side view of the car seat, the leg rest lifting mechanism is not easily exposed, thus ensuring the overall appearance of the car seat. At the same time, the elastic fabric allows the leg rest to be quickly lifted when the user is resting, with the elastic fabric covering the lifting mechanism, and it also covers the lifting mechanism when the user sits up.

[0026] To better understand the technical solutions and beneficial effects of this disclosure, the following detailed description is provided in conjunction with specific embodiments:

[0027] Please see Figures 1 to 4This is an embodiment of the electric seat structure 10 of the present invention, comprising a seat base 100, a seat leg rest 200, two seat armrests 300, two elastic fabrics 400, and a leg rest lifting mechanism 500. The seat base has a base contact surface 100a, and the seat leg rest 200 is connected to the base contact surface 100a. The two seat armrests 300 are respectively connected to opposite sides of the seat base 100, specifically the left and right sides of the seat base 100. One side of each elastic fabric 400 is connected to the side of the seat base 100 adjacent to the seat armrest 300, and each elastic fabric 400... The other side is connected to the seat leg rest 200. Specifically, one elastic fabric 400 is located on the left side of the seat base 100, and another elastic fabric 400 is located on the right side of the seat base 100. The leg rest lifting mechanism 500 is used to connect to an external power source. The lifting and rotation output end of the leg rest lifting mechanism 500 is connected to the seat leg rest 200 so that the leg rest lifting mechanism 500 can be used to lift or retract the seat leg rest 200. The seat leg rest 200 is lifted and rotated around the connection point with the base contact surface 100a so that a preset angle is formed between the seat leg rest 200 and the side of the base contact surface 100a.

[0028] In this embodiment, the electric seat structure 10 has an elastic fabric 400, which is connected to the seat armrest 300 and the seat leg rest 200. When the leg rest lifting mechanism 500 drives the seat leg rest 200 to lift it to a certain angle, the seat leg rest 200 stretches the elastic fabric 400, so that the elastic fabric 400 covers the leg rest lifting mechanism 500. From the side view of the car seat, the leg rest lifting mechanism 500 is not easily exposed, thus ensuring the overall appearance of the car seat. At the same time, the elastic fabric 400 allows the seat leg rest 200 to be quickly lifted when the user is resting, with the elastic fabric 400 covering the leg rest lifting mechanism 500, and the seat leg rest 200 to cover the leg rest lifting mechanism 500 when the user sits up.

[0029] like Figures 1 to 3 As shown, in one embodiment, a connecting gap 101 is formed between the seat base 100 and the seat armrest 300, and a portion of the elastic fabric 400 is located within the connecting gap 101. It can be understood that, in order to facilitate the connection of the elastic fabric 400 to the seat leg rest 200 and the seat armrest 300, a connecting gap 101 is provided between the seat base 100 and the seat armrest 300 to ensure that when the seat leg rest 200 is raised and rotated, there is no excessive friction between the elastic fabric 400 and the seat armrest 300 and / or the seat base 100, preventing the elastic fabric 400 from tearing due to excessive friction.

[0030] like Figure 4As shown, in one embodiment, the leg rest lifting mechanism 500 includes a drive motor 510 and a lifting bracket 520. The drive motor 510 is connected to an external power source, and its control output is connected to one end of the lifting bracket 520. The other end of the lifting bracket 520 is connected to the seat leg rest 200. The drive motor 510 drives the lifting bracket 520 to rotate, causing it to lift or retract the seat leg rest 200 by a certain angle. The elastic fabric 400 stretches when the seat leg rest 200 is lifted or rebounds when it retracts inward. During this process, the elastic fabric 400 always covers the drive motor 510 and the lifting bracket 520, ensuring the overall appearance of the car seat.

[0031] like Figure 4 As shown, the lifting bracket 520 further includes a first bracket 521, a rotating joint 522, and a second bracket 523. The first bracket 521 is movably connected to the second bracket 523 via the rotating joint 522. The first bracket 521 is connected to the control output terminal of the drive motor 510, and the second bracket 523 is also fixedly connected to the seat leg rest 200. It can be understood that the control output terminal of the drive motor 510 is the active drive component, the first bracket 521 is the driven component, and the second bracket 523 is a driven component relative to the first bracket 521. When the drive motor 510 performs a driving action, the first bracket 521 swings under the action of the drive motor 510. Since the seat leg rest 200 is connected to the seat base 100, and the second bracket 523 is also fixedly connected to the seat leg rest 200, the second bracket 523 swings around the rotating joint 522, thereby driving the seat leg rest 200 to lift and rotate.

[0032] In one embodiment, the preset angle range is 90-150°. It can be understood that, taking the front side of the seat base 100 as a reference, when the seat leg rest 200 retracts to abut against the reference, a 90° angle is formed between the seat leg rest 200 and the base contact surface 100a, i.e., a 0° angle is formed between the reference and the seat leg rest 200; when the seat leg rest 200 is raised to its maximum angle away from the reference, a 150° angle is formed between the seat leg rest 200 and the base contact surface 100a, i.e., a 60° angle is formed between the reference and the seat leg rest 200. Further, when the seat leg rest 200 is raised outward to its maximum angle, the first bracket 521 and the second bracket 523 are on the same horizontal line.

[0033] In one embodiment, the thickness of the elastic fabric 400 is 3mm-3.5mm. In this embodiment, the thickness of the elastic fabric 400 is 3mm, which gives the elastic fabric 400 high tensile strength and resilience while also providing good tensile strength.

[0034] In one embodiment, the electric seat structure 10 also includes a seat back (not shown) connected to the seat base 100.

[0035] In one embodiment, the angle formed between the seat back and the seat base 100 ranges from 100 to 115°. It is understood that when the angle between the seat back and the seat base 100 is within this range, it can accommodate a wider range of body types, thus improving seating comfort. In this embodiment, the angle formed between the seat back and the seat base 100 is 105°.

[0036] This disclosure also provides an automobile seat, including the electric seat structure 10 of any of the above embodiments.

[0037] Compared with the prior art, this disclosure has at least the following advantages:

[0038] The aforementioned electric seat structure 10 has an elastic fabric 400, which is connected to the seat armrest 300 and the seat leg rest 200. When the leg rest lifting mechanism 500 drives the seat leg rest 200 to lift it to a certain angle, the seat leg rest 200 stretches the elastic fabric 400, so that the elastic fabric 400 covers the leg rest lifting mechanism 500. From the side view of the car seat, the leg rest lifting mechanism 500 is not easily exposed, thus ensuring the overall appearance of the car seat. At the same time, the elastic fabric 400 allows the seat leg rest 200 to be quickly lifted when the user is resting, with the elastic fabric 400 covering the leg rest lifting mechanism 500, and the seat leg rest 200 to cover the leg rest lifting mechanism 500 when the user sits up.

[0039] The embodiments described above are merely illustrative of several implementations of this disclosure, and while the descriptions are specific and detailed, they should not be construed as limiting the scope of the disclosed patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this disclosure, and these all fall within the protection scope of this disclosure. Therefore, the protection scope of this patent should be determined by the appended claims.
