Description

Technical Field

[0001] This utility model belongs to the field of automotive seat technology and relates to a novel suspended electric two-way headrest. Background Technology

[0002] Car seat headrests play a crucial role in protecting people's necks and reducing cervical spine fatigue during daily travel. Floating car seat headrests are increasingly favored by consumers due to their unique design. Chinese Patent CN 119428396A discloses an adjustable height floating car seat headrest and a car seat, but this floating headrest is primarily adjusted manually. Chinese Patent CN 118991576A discloses a floating car seat headrest that can be electrically adjusted, but the electric drive mechanism of this headrest is directly connected to the headrest structure (drive rod 603 serves as the drive end of the electric drive mechanism and is fixed to the front cover 102 with bolts). The electric drive mechanism uses a worm gear design, which requires clearance holes on the fixing components and the rear cover of the headrest, resulting in an unattractive appearance and limited vertical travel due to the headrest's size. Summary of the Invention

[0003] In view of the shortcomings and deficiencies of the existing technology, the purpose of this utility model is to provide a new type of suspended electric two-way headrest. This headrest separates the electric two-way mechanism from the headrest structure. The electric up-and-down mechanism is arranged on the upper part of the seat back, and the headrest is suspended at the front of the backrest. Compared with the previous electric suspended headrest, it has a more beautiful shape and a greater adjustment range.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A novel suspended electric two-way headrest includes a headrest body and a headrest electric frame. The headrest body is suspended at the front end of the seat back, and the headrest electric frame is installed on the upper part of the seat back. It includes a headrest rod, a crossbeam installed on the upper end of the headrest rod, a motion bracket that can move up and down relative to the headrest rod, a motor for driving the motion bracket, and a motor bracket fixed on the headrest rod. The front of the motion bracket is fixedly connected to the headrest body, and guide sleeves are provided on both sides. The guide sleeves are slidably connected to the headrest rod. The motor is a lead screw motor, which is installed and fixed on the motor bracket. A lead screw end sleeve is threadedly connected to the lead screw motor screw, and the lead screw end sleeve is installed and fixed on the bottom surface of the motion bracket.

[0006] As a preferred embodiment of this utility model, the lower end of the headrest rod is installed on the seat back, and the crossbeam has an assembly part near the lower part of both ends. The assembly part is set in the assembly hole at the upper end of the headrest rod, and the crossbeam is connected to the headrest rod by a metal pin.

[0007] As a preferred embodiment of this invention, the top surface of the motion support is provided with a clearance hole at a position opposite to the screw.

[0008] As a preferred embodiment of this utility model, the headrest body includes a headrest cover, a soft pad, foam, a front shell, and a frame, and the front of the motion support is connected to the frame by screws.

[0009] As a preferred embodiment of this utility model, the frame is provided with a speaker mounting slot, the speaker is installed in the speaker mounting slot and sealed at the connection by a sealing ring, the front shell is provided with a receiving slot that conforms to the shape of the speaker at the position opposite to the speaker, the receiving slot is machined with a sound hole, after the front shell and the frame are assembled, the speaker is encapsulated inside, and the speaker is connected to the vehicle controller through a wiring harness.

[0010] As a preferred embodiment of this invention, the frame is further provided with magnets.

[0011] Advantages and beneficial effects of this utility model:

The lead screw motor is fixed to the motor bracket 25 by screws. The lead screw motor screw 241 is threaded with a screw end sleeve 28. The screw end sleeve 28 is fixed to the bottom surface of the motion bracket 23 by screws. The rotation of the lead screw motor screw 241 drives the screw end sleeve 28 and the motion bracket 23 to move up and down along the screw, and drives the headrest body 1 to move up and down through the motion bracket 23.

[0025] Furthermore, such as Figure 3 As shown in this embodiment, the top surface of the motion bracket 23 is provided with a clearance hole at a position opposite to the screw 241.

[0026] Furthermore, such as Figure 2 As shown, in this embodiment, the headrest body 1 includes a headrest cover 11, a soft pad 12, a foam 13, a front shell 14, and a frame 15. The front of the motion support 23 is connected to the frame 15 by four screws.

[0027] Furthermore, continue as Figure 2 As shown, in this embodiment, the frame 12 is provided with a speaker mounting slot, the speaker 16 is installed in the speaker mounting slot and sealed at the connection by a sealing ring 17, the front shell 14 is provided with a receiving groove that conforms to the shape of the speaker at the position opposite to the speaker 16, and the receiving groove is machined with a sound hole. After the front shell 14 and the frame 15 are assembled, the speaker 16 is encapsulated inside, and the speaker 16 is connected to the vehicle controller through a wiring harness.

[0028] Furthermore, continue as Figure 2As shown, in this embodiment, the frame 15 is also provided with a magnet 18. The magnet 18 facilitates the installation of a soft pillow with built-in magnets on the headrest body 1 by magnetic attraction.

[0029] The above describes specific embodiments of this utility model, but the scope of protection of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the scope of protection of this utility model. Therefore, the scope of protection of this utility model should be determined by the scope of the claims.
