Description

Technical Field

[0001] This utility model belongs to the field of seat technology, and in particular relates to a detachable music headrest for a car seat. Background Technology

[0002] The traditional headrest speaker module in a chair is connected to the main seat cable via a wiring harness that passes through a guide rod. Its drawbacks are:

[0003] 1. Difficult to disassemble: The wiring harness is electrically connected to the horn and the horn controller on the vehicle body, which makes it impossible to separate the headrest independently. The wiring harness must be disconnected first before it can be separated.

[0004] 2. Limited adjustment: When adjusting the headrest height, the wiring harness is easily pulled, leading to poor contact;

[0005] 3. Unable to switch between seat mode and bed mode: Because the headrests cannot be removed, the front seat backrests interfere with the rear seat cushions when folded back. Summary of the Invention

[0006] The purpose of this invention is to provide a detachable music headrest for a car seat that allows for quick removal of the headrest, eliminates the need for manual wiring harness plugging and unplugging, and allows for adjustable headrest height.

[0007] The purpose of this utility model is to solve the following problem:

[0008] A detachable music headrest for a car seat includes a headrest body, two headrest guide rods fixed to the headrest body, and a headrest guide sleeve installed on the top of the car seat. The two headrest guide rods are detachably inserted into the headrest guide sleeve. Speakers are respectively provided on both sides of the headrest body. At least one of the headrest guide rods is a hollow guide rod. The conductive wires of all the speakers are gathered into a first wiring harness assembly and electrically connected to a first terminal fixed inside the hollow guide rod. Two or more contact springs fixed to the first terminal extend downwards and are circumferentially spaced. The contact springs have a direction towards the head... The inner wall of the headrest guide sleeve has a protruding contact part. The second terminal fixed inside the headrest guide sleeve is electrically connected to a conductive contact piece fixed on the inner wall of the headrest guide sleeve and matched with each of the contact springs. When the hollow guide rod is inserted into the headrest guide sleeve, the contact parts of each contact spring are electrically connected to the corresponding conductive contact piece. The second terminal is electrically connected to a second wiring harness assembly that is electrically connected to all the conductive contact pieces. The second wiring harness assembly leads out of the headrest guide sleeve and is electrically connected to an electrical plug or electrical socket. The length of the conductive contact piece is adapted to the height adjustment of the headrest body.

[0009] As a further optimization of the above technical solution, the electrical plug or socket can be electrically connected to an electrical socket or plug that is electrically connected to the horn controller on the vehicle body.

[0010] As a further optimization of the above technical solution, mounting holes are provided on the mounting plates on both sides of the headrest body, and a speaker located inside the inner cavity of the headrest body is installed in each mounting hole.

[0011] As a further optimization of the above technical solution, the conductive wire of the speaker is fixed in place within the inner cavity of the headrest body by a snap fastener.

[0012] As a further optimization of the above technical solution, the side wall of the hollow guide rod is provided with openings spaced circumferentially, and the contacting parts of two or more contacting springs fixed on the first terminal are exposed from the openings.

[0013] As a further optimization of the above technical solution, the electrical contact part has a smoothly transitioned arc-shaped surface.

[0014] As a further optimization of the above technical solution, the top corner of the conductive contact has a smoothly transitioned arc surface, so that the contacting part of the contact spring can slide smoothly up and down on the conductive contact.

[0015] As a further optimization of the above technical solution, the headrest guide sleeve is provided with a wire hole, and the second wire harness assembly is led out from the wire hole of the headrest guide sleeve and electrically connected to an electrical plug or electrical socket.

[0016] As a further optimization of the above technical solution, the first terminal is a ring-shaped body, and two or more of the aforementioned contact springs extend downward and are fixed on the ring-shaped body at circumferential intervals.

[0017] As a further optimization of the above technical solution, the second terminal is a ring-shaped body, with one end of all the conductive contacts fixed on the ring-shaped body and the other end circumferentially spaced and fixed on the inner wall of the headrest guide sleeve.

[0018] The advantages of this invention compared to the prior art are:

[0019] 1. The speaker wire of this utility model is slidably connected to the conductive contact through a contact spring, so that when removing the seat headrest, there is no need to manually plug and unplug the wire harness, thus enabling quick removal of the seat headrest.

[0020] 2. The height of the headrest of this utility model is adjustable. Because this utility model uses a contact spring and a conductive contact piece, the length of the conductive contact piece is adapted to the height adjustment of the headrest body, thereby making the height of the headrest adjustable.

[0021] 3. The headrest of the seat in this utility model is detachable. When the headrest is removed, the backrest of the front seat can be folded back without interfering with the seat cushion of the rear seat, thus realizing the interchange between seat mode and bed mode.

[0022] 4. This utility model has a simple structure, low production cost, convenient operation, and good riding comfort, making it suitable for music seats. Attached Figure Description
