Description

Technical Field

[0001] The utility model relates to the technical field of automobile seats, in particular to a leg rest and a seat with liftable side wings to prevent slipping. Background Art

[0002] Zero-gravity car seats have become a common feature of high-end models today. The new riding experience they bring to passengers greatly improves driving comfort. One of the core components of zero-gravity seats is the leg rest.

[0003] For example, a car seat leg rest disclosed in a Chinese patent includes a leg rest base, and the leg rest base includes side walls at both ends of the top, the side walls of the leg rest base are rotatably connected to a second connecting arm and a third connecting arm, one end of the second connecting arm is rotatably connected to a first connecting arm, one end of the third connecting arm is rotatably connected to a rotating plate, a fixed rod is commonly fixedly connected between the opposite sides of the two rotating plates, and the other ends of the two rotating plates are commonly penetrated and connected to a rotating rod. When the backrest connecting plate rotates, the seat back can be adjusted, and when the rotating plate rotates, the distance between the backrest connecting plate and the leg rest base can be adjusted through the first connecting arm and the third connecting arm, so that the height of the seat can be adjusted. The structure is simple, and the seat can be automatically adjusted, and at the same time, it has better stability.

[0004] However, seat leg rests of the types mentioned above are mostly limited by the smaller space, and the width of the leg rest is designed to be narrow. Placing the legs on the leg rest when using it will feel cramped. If you are not careful, the legs will slide from both sides due to inertia when the car turns. The stability is poor, and the legs need to be constantly adjusted to be placed back on the leg rest. When taking a nap in zero-gravity mode, you may even be awakened by your legs slipping, which greatly affects the comfort of use. Utility Model Content

[0036] Embodiment 1: Figure 1-Figure 4 As shown, this embodiment proposes a leg rest with liftable side wings to prevent slipping, including a main body part 1 installed on a seat 3, with side wing parts 2 installed on both sides of the main body part 1, one end of the side wing part 2 protruding from the outside of the main body part 1 to form an angle with the main body part 1, and a first flipping mechanism is provided between the side wing part 2 and the main body part 1, and the first flipping mechanism is used to fold the side wing part 2 to the side and rear of the main body part 1. The side wing part 2 forms an oblique support surface on both sides of the main body part 1 to provide lateral support for the legs of the passenger. The first flipping mechanism can fold the side wing part 2 to the side and rear of the main body part 1, and when the main body part 1 is fully closed, it ensures that the leg rest can be smoothly folded into the lower part of the seat 3, saving space in the vehicle.

[0037] In this embodiment, the first flipping mechanism includes a transmission assembly 41 and a first driving member 42. The first driving member 42 is fixedly mounted on the main body 1. The first driving member 42 is a double-headed motor. One end of the transmission assembly 41 is in transmission connection with the wing portion 2, and the other end is in transmission connection with the first driving member 42. By controlling the operation of the first driving member 42, the wing portion 2 can be automatically folded through the transmission assembly 41 without manually turning the wing portion 2 to rotate. In this embodiment, two groups of transmission assemblies 41 are provided, and the two groups of transmission assemblies 41 are respectively fixedly connected to the two output shafts of the double-headed motor to improve the stability of the force on the wing portion 2, so as to ensure the stability of the wing portion 2 during the folding process.

[0038] In this embodiment, the transmission assembly 41 includes a rotating shaft 411 and a flip skeleton 412. The rotating shaft 411 is rotatably mounted on the main body 1. One end of the flip skeleton 412 is fixedly connected to the rotating shaft 411, and the other end is fixedly connected to the side wing part 2. In this embodiment, the flip skeleton 412 is fixedly connected to the side wing part 2 by bolts, and the flip skeleton 412 is fixedly connected to the rotating shaft 411 by welding. When the first driving member 42 is working, it drives the rotating shaft 411 to rotate, the rotating shaft 411 drives the flip skeleton 412 to rotate, and the flip skeleton 412 drives the side wing part 2 to fold. The transmission is stable and the space occupation of the transmission assembly 41 is effectively reduced. In this embodiment, after the side wing part 2 is folded outward, the maximum angle formed between the side wing part 2 and the plane of the main body 1 is 120°.

[0039] In this embodiment, both sides of the back of the main body 1 are fixedly connected with the first mounting bracket 11, the rotating shaft 411 is rotatably mounted on the first mounting bracket 11, and the first driving member 42 is fixedly mounted on the first mounting bracket 11. It is convenient to install the rotating shaft 411 and the first driving member 42 for subsequent maintenance.

[0040] In this embodiment, a reinforcing plate 413 is provided at the connection end between the flip skeleton 412 and the wing part 2 to enhance the stability of the connection between the flip skeleton 412 and the wing part 2 and to improve the supporting strength of the flip skeleton 412 to the wing part 2.

[0041] In this embodiment, a second flipping mechanism is arranged between the main body 1 and the seat 3. The second flipping mechanism comprises a second mounting bracket 51, a connecting rod assembly 52 and a second driving member 53. The second mounting bracket 51 is fixedly mounted on the seat 3.

The second driving member 53 is in transmission connection with the connecting rod assembly 52. ​​The connection between the main body 1 and the seat 3 is realized, and the automatic folding of the main body 1 can be realized by controlling the operation of the second driving member 53. A rotating shaft is arranged at the rotating part of the connecting rod assembly 52, and a reinforcing tube is welded in the middle. The connecting rod mechanism is connected to the second mounting bracket 51 through the rotating shaft. The second driving member 53 drives the power rod to move forward, and the power rod pushes the connecting rod assembly 52 to fold. The second driving member 53 drives the power rod to move backward, and the power rod pulls the connecting rod assembly 52 to fold. In this embodiment, the maximum angle between the main body 1 and the vertical plane of the seat 3 after being folded outward is 70°. Since the transmission principle of the connecting rod assembly 52 has been fully disclosed in the prior art, it will not be described in detail here.

[0042] The usage principle of this embodiment is as follows:

[0043] First, by controlling the second driving member 53 to work, the second driving member 53 pushes the main body part 1 outward through the connecting rod assembly 52.

[0044] Subsequently, by controlling the operation of the first driving member 42, the output shafts at both ends of the first driving member 42 rotate the shaft 411. During the rotation of the shaft 411, the side wing parts 2 are driven to fold outward by flipping the frame 412, so that the side wing parts 2 form oblique supporting surfaces on both sides of the main body part 1, providing lateral support for the legs of the passenger.

[0045] After use, the first driving member 42 and the second driving member 53 are controlled to operate so that the side wing portion 2 is folded to the side and rear of the main body portion 1 , and then the main body portion 1 is folded to the lower part of the seat 3 .
