[0003] As the core seating carrier for the driver and front passenger, the adjustment performance and functional adaptability of the car front seat directly affect driving safety and riding experience. Currently, existing car front seat kits have the following problems: most front seat kits only support backrest angle and seat cushion fore-and-aft sliding adjustment, lacking the function of adjusting the headrest height and angle. They also have poor adaptability to the differences in lumbar spine curves for different leg lengths, which can easily lead to neck fatigue with long-term use and affect the driver's safe driving operation. To address the above problems, a car front seat kit with multi-directional adjustment function is proposed to solve these issues. Utility Model Content

[0004] The purpose of this section is to outline some aspects of embodiments of the present invention and to briefly describe some preferred embodiments. Simplifications or omissions may be made in this section, as well as in the abstract and title of the present invention, to avoid obscuring the purpose of these documents, and such simplifications or omissions should not be construed as limiting the scope of the present invention.

[0005] Therefore, the purpose of this utility model is to provide a car front seat kit with multi-directional adjustment function, which can solve the technical problem that the existing lack of headrest height and angle adjustment function, which can easily lead to neck fatigue and affect the driver's safe driving operation after long-term use.

[0006] To solve the above-mentioned technical problems, this utility model provides a car front seat kit with multi-directional adjustment function, adopting the following technical solution: It includes a seat cushion, with guide connecting plates fixedly installed on both sides of the outer wall of the seat cushion, and a protective cover fixedly installed on the outer side of one of the guide connecting plates. An adjustment motor is fixedly installed inside the protective cover, and a backrest is fixedly connected to the output end of the adjustment motor. A headrest is installed above the backrest, and a limiting structure is provided at the upper end of the backrest. The limiting structure includes a limiting frame fixedly installed at the upper end of the backrest. A pull rod is slidably installed inside the limiting frame and fixedly installed on the outer wall of a positioning pin. A return spring is sleeved on the outer wall of the positioning pin. Two guide slide rods are symmetrically installed below the headrest and slide friably inside the backrest. A base frame is provided below the seat cushion, and a buffer structure is provided below the base frame.

[0007] Optionally, one of the guide slide rods has equidistant positioning holes on its outer wall, the upper end of the limiting frame has a guide groove, the pull rod is slidably connected inside the guide groove, and the outer wall of the positioning pin is slidably connected inside the limiting frame, with one end of the positioning pin being engaged inside the positioning hole.

[0008] Optionally, a limiting block is fixedly installed inside the limiting frame, and the limiting block and the positioning pin are slidably connected, with the reset spring located between the pull rod and the limiting block.

[0017] 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.

[0018] The following is in conjunction with the appendix Figure 1 —5. This utility model will be described in further detail.

[0019] Reference Figure 1-5 In this embodiment, in order to solve the technical problem that the existing lack of headrest height and angle adjustment function, which can easily lead to neck fatigue and affect the driver's safe driving operation, this utility model discloses a car front seat kit with multi-directional adjustment function. The seat includes a seat cushion 1. Guide connecting plates 2 are fixedly installed on both sides of the outer wall of the seat cushion 1, and a protective cover 3 is fixedly installed on the outer side of one of the guide connecting plates 2. An adjustment motor 31 is fixedly installed inside the protective cover 3. The output end of the adjustment motor 31 is fixedly connected to a backrest 4. A headrest 5 is installed above the backrest 4. A limiting structure 6 is installed at the upper end of the backrest 4. The limiting structure 6 includes a limiting frame 61 fixedly installed at the upper end of the backrest 4. A pull rod 63 is slidably installed inside the limiting frame 61 and is fixedly installed on the outer wall of the positioning pin 64. A return spring 66 is sleeved on the outer wall of the positioning pin 64. Two guide slide rods 51 are symmetrically installed below the headrest 5 and slide against the backrest 4. A base frame 8 is installed below the seat cushion 1. A buffer structure 7 is installed below the base frame 8. Specifically, one of the guide slide rods 51 has equidistant positioning holes 52 on its outer wall, the upper end of the limit frame 61 has a guide groove 62, the pull rod 63 is slidably connected inside the guide groove 62, and the outer wall of the positioning pin 64 is slidably connected inside the limit frame 61, with one end of the positioning pin 64 being engaged inside the positioning hole 52.

[0020] By designing the positioning pin 64 and the positioning hole 52 to be the same size, the positioning pin 64 and the limit bracket 61 can slide effectively, so that the positioning pin 64 and the positioning hole 52 can be engaged relatively accurately. Specifically, a limit block 65 is fixedly installed inside the limit frame 61, and the limit block 65 and the positioning pin 64 are slidably connected. The reset spring 66 is located between the pull rod 63 and the limit block 65.

[0021] One end of the return spring 66 is fixed to the outside of the pull rod 63, while the other end of the return spring 66 is attached to the limit block 65, thereby pulling the pull rod 63 to drive the positioning pin 64 to squeeze the return spring 66 on the limit block 65 to deform it, thereby facilitating the height adjustment of the headrest 5. Specifically, two guide sliders 9 are symmetrically installed on both sides of the seat cushion 1, and an installation rod 91 is fixedly installed between the guide sliders 9. Two sliding grooves 81 are opened on both sides inside the base frame 8, and the guide sliders 9 slide in the sliding grooves 81.

[0022] Two sets of guide sliders 9 drive the mounting rod 91 to slide in the groove 81 inside the base frame 8, which facilitates the adjustment of the front and rear position of the seat cushion 1, thereby effectively placing the driver's legs and avoiding obstruction; Specifically, the buffer structure 7 includes a base plate 71 fixedly installed on the car base. Multiple dampers 72 are symmetrically installed inside the base plate 71, and buffer springs 73 are sleeved on the outside of the dampers 72. The dampers 72 are in close contact with the base frame 8.

[0023] By setting multiple dampers 72 and buffer springs 73, the vibration pressure on the car can be effectively buffered and the pressure can be distributed, thereby reducing the driver's bumpiness.

[0024] Specifically, a rubber buffer pad 74 is fixedly installed inside the upper end of the base plate 71, and centrifugal fans are fixedly installed inside the seat cushion 1 and the backrest 4.

[0025] By setting up a rubber buffer pad 74, the seat cushion 1 can be effectively cushioned during driving, and the vibration pressure can be dispersed. The centrifugal fan can be set up to ventilate the seat and improve the driver's comfort.

[0026] The specific working principle is as follows: When a taller user drives, the two sets of guide sliders 9 under the seat cushion 1 move backward through the slide grooves 81 in the base frame 8. This causes the two sets of guide sliders 9 to move the seat cushion 1 on the two mounting rods 91. At the same time, the adjusting motor 31 inside the protective cover 3 drives the backrest 4 to rotate, causing the backrest 4 to adjust the position of the headrest 5 to a comfortable position for the user. The headrest 5 is also adjusted in height by sliding the guide slider 51 within the backrest 4. Then, by releasing the pull rod 63, the spring force of the return spring 66... The lower positioning pin 64 slides within the limiting bracket 61, thereby engaging one end of the positioning pin 64 with the positioning hole 52. This facilitates effective positioning of the headrest 5, allows for flexible adjustment of the seat position, backrest angle 4, and headrest height 5, and provides protection for the user's cervical spine. Simultaneously, during driving, the car experiences bumps, and the multiple dampers 72 and buffer springs 73 on the base plate 71 below the chassis 8 work together to disperse vibration pressure. Additionally, the rubber buffer pad 74 further disperses the pressure, effectively cushioning and reducing shock for the seat cushion 1 during driving.
