Description

Technical Field

[0001] This utility model relates to the field of seat back panel technology, and in particular to an adjustable carbon fiber seat back panel. Background Technology

[0002] With the development of the seating industry, more and more types of seats are appearing on the market. A seat is a type of seating furniture with a backrest, and some also have armrests. The backrest is an essential component of a seat and is often used to allow people to lean back.

[0003] Modern chairs offer different effects due to the different materials used in their construction, such as wooden back panels, plastic back panels, or carbon fiber back panels. Among these, carbon fiber back panels are preferred because they offer better hardness and toughness.

[0004] However, the headrest of the aforementioned carbon fiber seat back panel does not have an adjustment mechanism, making it impossible to adjust the angle and height of the headrest. Due to the different needs of seat users, such as some people feeling more comfortable when their head is tilted back, or those who are taller, the headrest cannot be aligned with their head, thus failing to meet their needs well. Therefore, we propose an adjustable carbon fiber seat back panel. Utility Model Content

[0005] The purpose of this utility model is to provide an adjustable carbon fiber seat back panel. By setting an adjustment mechanism, the height of the headrest can be easily adjusted using a telescopic rod assembly. Then, by using the cooperation of a connecting base, a rotating block, a limiting assembly, and a pushing assembly, the angle of the headrest can be adjusted.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an adjustable carbon fiber seat backrest, comprising a backrest body and a headrest located above the backrest body, wherein an adjustment mechanism is provided between the backrest body and the headrest, the adjustment mechanism comprising:

[0007] Telescopic rod assembly, which is connected to the top of the back panel body and is used to adjust the height of the headrest;

[0008] A connecting base is fixedly connected to one end of the telescopic rod assembly. A rotating block is rotatably connected inside the connecting base, and one end of the rotating block is fixedly connected to the bottom of the headrest.

[0009] A limiting component is disposed inside the rotating block and is used to limit the position of the rotating block;

[0010] A push-up assembly is disposed between the limiting assembly and the headrest, and the push-up assembly is used to push up the limiting assembly.

[0011] Preferably, the connecting base is composed of an L-shaped piece and two side pieces fixedly connected to the side of the L-shaped piece, and the top of each side piece is set to be arc-shaped.

[0012] Preferably, the limiting component includes:

[0013] A cavity is formed inside the rotating block, and a U-shaped block is slidably connected inside the cavity;

[0014] A movable rod is fixedly connected to the middle of the U-shaped block, and a return spring is sleeved on the outer surface of the movable rod. Limit rods are fixedly connected to both ends of the U-shaped block.

[0015] Multiple limiting grooves are provided on the outer surface of the side plate, and the side edges of the side plate are all fixedly provided with protruding teeth. The two sides of the middle part of the rotating block are provided with sliding grooves.

[0016] Two rotating columns are fixedly connected to both sides of the rotating block, and the rotating block is rotatably connected to the connecting base through the two rotating columns.

[0017] Preferably, the push-up assembly includes a pressure sleeve fixedly connected to the top of the movable rod, a pressing rod inserted into the headrest, a pressing block fixedly connected to one end of the pressing rod, and a fixed circular block fixedly connected to one end of the pressing rod extending to the outside of the headrest, wherein the pressing block is configured as a triangular block.

[0020] The technical effects and advantages of this utility model are as follows:

[0021] The headrest height is adjusted using a telescopic rod assembly to accommodate users of different body types. Then, a pushing assembly pushes a limiting assembly, causing the limiting assembly to no longer restrict the rotating block, allowing the rotating block to rotate along the connecting base and thus adjusting the headrest's deflection angle. Subsequently, the pushing assembly stops pressing against the limiting assembly, and the limiting assembly then fixes the position of the rotating block. This design allows for adjustment of the headrest's deflection angle to meet the needs of different user groups. Attached Figure Description

[0028] 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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] This utility model provides, for example Figure 1-5 The image shows an adjustable carbon fiber seat back panel.

[0030] Example 1

[0031] The device includes a back panel body 1 and a headrest 2 located above the back panel body 1. An adjustment mechanism is provided between the back panel body 1 and the headrest 2. The adjustment mechanism includes: a telescopic rod assembly 3, which is connected to the top of the back panel body 1 and is used to adjust the height of the headrest 2; a connecting base 4, which is fixedly connected to one end of the telescopic rod assembly 3, and a rotating block 5 is rotatably connected inside the connecting base 4, with one end of the rotating block 5 fixedly connected to the bottom of the headrest 2; a limiting component 6, which is disposed inside the rotating block 5 and is used to limit the position of the rotating block 5; and a pushing component 7, which is disposed between the limiting component 6 and the headrest 2. The actuating component 7 is used to actuate the limiting component 6. The height of the headrest 2 is adjusted by using the telescopic rod component 3 to accommodate users of different body types. Then, the actuating component 7 actuates the limiting component 6, so that the limiting component 6 no longer limits the rotating block 5, allowing the rotating block 5 to rotate along the connecting base 4, thereby adjusting the deflection angle of the headrest 2. Subsequently, the actuating component 7 no longer presses against the limiting component 6, and the limiting component 6 is used to limit and fix the position of the rotating block 5. This design can adjust the deflection angle of the headrest 2 to meet the needs of different user groups. For example, for users who prefer to tilt their heads back, the core of the back panel body 1 can be made of carbon fiber.

[0032] Furthermore, the connecting base 4 is composed of an L-shaped piece and two side pieces fixedly connected to the side of the L-shaped piece, and the top of each side piece is set to be arc-shaped; so that the rotating block 5 can rotate along the inside of the connecting base 4.

[0033] Furthermore, the limiting component 6 includes: a cavity 601, which is formed inside the rotating block 5, and a U-shaped block 602 is slidably connected inside the cavity 601; a movable rod 603, which is fixedly connected to the middle of the U-shaped block 602, and a return spring 604 is sleeved on the outer surface of the movable rod 603; limiting rods 605 are fixedly connected to both ends of the U-shaped block 602; and multiple limiting grooves 606, which are formed on the outer surface of the side plate, and protruding teeth 607 are fixedly provided on the side edges of the side plate. Both sides of the part are provided with sliding grooves 609; two rotating columns 608 are fixedly connected to both sides of the rotating block 5, and the rotating block 5 is rotatably connected to the connecting base 4 through the two rotating columns 608; the pushing assembly 7 includes a pressure sleeve 703 fixedly connected to the top of the movable rod 603, a pressing rod 701 inserted into the headrest 2, a pressing block 702 fixedly connected to one end of the pressing rod 701, and a fixed round block 704 fixedly connected to one end of the pressing rod 701 extending to the outside of the headrest 2, and the pressing block 702 is set as a triangle. The block; by pressing the fixed round block 704, the fixed round block 704 drives the pressing rod 701 to move, thereby driving the pressing block 702 to move, causing the pressing block 702 to press the pressure sleeve 703, thereby driving the pressure sleeve 703 and its movable rod 603 to move upward together, thereby driving the U-shaped block 602 and its limiting rod 605 to move upward, while compressing the return spring 604 until the limiting rod 605 separates from the limiting groove 606. Then, the rotating block 5 can be rotated along the rotating column 608, thereby driving the headrest 2 to rotate. When the headrest 2 is adjusted... After the deflection angle is adjusted, the fixed round block 704 is released, and the return spring 604 drives the movable rod 603 and its U-shaped block 602 to return to their original positions. This allows the limiting rod 605 to engage with the corresponding limiting groove 606 again. At the same time, the design of the protruding teeth 607 can temporarily limit the limiting rod 605 during the rotation of the headrest 2, allowing the limiting rod 605 to move along the protruding teeth 607. This allows the user to move without having to keep pressing the fixed round block 704. The sliding groove 609 is for the purpose of facilitating the sliding of the limiting rod 605.

[0034] Furthermore, the telescopic rod assembly 3 includes a fixed frame 301 fixedly connected to the top of the back panel body 1, a telescopic rod 302 inserted into the fixed frame 301, and a locking assembly 303 disposed on one side of the fixed frame 301. The telescopic rod 302 is fixedly connected to the bottom of the connecting base 4. The height of the headrest 2 is adjusted by sliding the telescopic rod 302 along the inside of the fixed frame 301. Then, the position of the telescopic rod 302 is locked by the locking assembly 303, thereby fixing the position of the headrest 2.

[0035] Example 2

[0036] Example 2 further discloses, based on Example 1, that the locking assembly 303 includes a locking threaded rod threadedly connected to one side of the middle of the fixed frame 301 and a rotating block fixedly connected to one end of the locking threaded rod, and the outer surface of the rotating block is provided with anti-slip texture; by rotating the rotating block, the locking threaded rod can be driven to rotate, thereby using the locking threaded rod to squeeze the telescopic rod 302, thereby fixing the telescopic rod 302.
