Description

Technical Field

[0001] This utility model relates to the field of flexible guide rail frame technology, specifically a flexible guide rail frame for a backrest chair. Background Technology

[0002] With technological advancements and improved living standards, car seats are increasingly accepted and favored by users. Existing car backrests typically feature integrated guide rails on both sides of the seating / reclining area. The massage mechanism on the backrest can slide along these rails and move back and forth between the head, buttocks, or legs, providing massage to these areas. However, these types of backrests have the following problems: the posture of the human body is fixed. Since the guide rails on both sides of the seating / reclining area are integrated, the angle between the sections of the guide rails facing the back and buttocks is fixed. Therefore, the degree of lumbar flexion when sitting or lying on the backrest is fixed and the sitting / reclining posture cannot be changed. Utility Model Content

[0003] The purpose of this utility model is to provide a flexible guide rail frame for a backrest chair to solve the above-mentioned technical problems.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a flexible guide rail frame for a backrest chair, comprising a backrest frame, a seat frame, and a base frame. One side of the backrest frame is connected to the seat frame, and the bottom of the backrest frame is connected to the base frame. A leg support frame is connected to the side of the seat frame away from the backrest frame. A first electric push rod is provided between the leg support frame and the base frame. The first electric push rod is connected to the leg support frame via a first top rod. A second electric push rod is also provided on the base frame. The second electric push rod is connected to the backrest frame via a U-shaped tube. Swing frame frames are also provided on both sides of the base frame. The upper side of the swing frame frames is connected to the backrest frame.

[0005] Preferably, the seat frame is also provided with a seat guide rail, and the backrest frame is provided with a backrest guide rail at the bottom.

[0006] Preferably, a backrest support plate is provided on the backrest iron frame, and a seat support plate is provided on the seat iron frame.

[0007] Preferably, a first drive motor is provided on one side of the first electric push rod, and a second drive motor is provided on one side of the second electric push rod.

[0008] Preferably, a U-shaped support plate is also provided on one side of the backrest iron frame.

[0009] Preferably, a seat rotation support is also provided below the seat frame.

[0010] Preferably, the leg-shaping iron frame is equipped with guide wheels.

[0011] Preferably, the base frame is also provided with guide wheels.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] The backrest frame moves and adjusts its angle via a second electric push rod, making the angle of the seat frame assembly different from that of the backrest frame assembly. This achieves different angles for the seat and backrest in the initial state, thus enabling flexibility. The first electric push rod is fixed to the front square tube of the backrest frame and pushes the leg support frame. In this way, the leg support frame moves with the different angles of the backrest frame, avoiding the traditional method of moving with the seat frame and preventing interference.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figure 1-4 This utility model provides a technical solution: a flexible guide rail iron frame for a backrest chair, including a backrest iron frame 1, a seat iron frame 2, and a base iron frame 3. One side of the backrest iron frame 1 is connected to the seat iron frame 2, and the bottom of the backrest iron frame 1 is connected to the base iron frame 3. A leg support iron frame 4 is connected to the side of the seat iron frame 2 away from the backrest iron frame 1. A first electric push rod 5 is provided between the leg support iron frame 4 and the base iron frame 3. The first electric push rod 5 is connected to the leg support iron frame 4 through a first top rod 6. A second electric push rod 7 is also provided on the base iron frame 3. The second electric push rod 7 is connected to the backrest iron frame 1 through a U-shaped tube 8. A swing frame iron frame 9 is also provided on both sides of the base iron frame 3. The upper side of the swing frame iron frame 9 is connected to the backrest iron frame 1.

[0023] Specifically, the seat frame 2 is also equipped with a seat guide rail 10, and the backrest frame 1 is equipped with a backrest guide rail 11 at the bottom. Through the above settings, the backrest and seat of the chair can be flexibly tilted forward and backward to meet the needs of different users.

[0024] Specifically, a backrest support plate 12 is provided on the backrest iron frame 1, and a seat support plate 13 is provided on the seat iron frame 2. Through the above settings, the support of the backrest iron frame 1 and the seat iron frame 2 is more stable, and the user can obtain better comfort and stability during use.

[0025] Specifically, a first drive motor 14 is provided on one side of the first electric push rod 5, and a second drive motor 15 is provided on one side of the second electric push rod 7.

[0026] Specifically, a U-shaped support plate 16 is also provided on one side of the backrest iron frame 1. By providing the U-shaped support plate 16, the structure of the backrest iron frame 1 becomes more robust and can withstand greater pressure and tension, thereby improving the durability of the entire backrest chair.

[0027] Specifically, a seat rotation support 17 is also provided below the seat frame 2. By providing the seat rotation support 17, the position of the rotation point of the seat frame 2 remains unchanged under the action of the seat rotation support 17, so that the angle of the seat frame 2 is different from the angle of the backrest frame 1, thereby realizing different angles of the seat and backrest in the initial state and achieving flexibility.

[0028] Specifically, the leg support frame 4 is equipped with guide wheels 18, and furthermore, the base frame 3 is also equipped with guide wheels 18. By setting the guide wheels 18, the chair backrest is more flexible during use, and users can adjust the position according to their needs.

[0029] A specific application example of this embodiment is as follows:

[0030] Users can control the activation of the first drive motor 14 and the second drive motor 15 to achieve automatic adjustment of the backrest and seat. When the user needs to adjust the backrest angle, he / she only needs to press the corresponding button, and the first drive motor 14 will drive the first electric push rod 5, which will move the leg support frame 4 back and forth through the first push rod 6, thereby changing the tilt angle of the backrest. When adjusting the seat angle, the second drive motor 15 will work, and the second electric push rod 7 will act on the backrest frame 1 through the U-shaped tube 8 to achieve the back and forth tilt of the seat.
