Description

Technical Field

[0001] The utility model relates to the technical field of vehicle seat headrests, in particular to a headrest connector. Background Art

[0002] In the process of implementing the utility model, the inventor found that the prior art has at least the following problems:

[0003] At present, users have more and more diversified demands for car seats, and they require headrests with audio, electric adjustment function, etc.

[0004] If the traditional connection scheme is adopted, it will inevitably lead to the requirement that the headrest with electric function cannot be freely disassembled and installed.

[0005] Japanese patent application JP2008-49820 discloses an example of a lead connection structure with such a headrest. In the present invention, a structure is adopted in which a first connector constituting a connection terminal of a lead connected to an electrical component arranged on the headrest side is combined with a second connector constituting a connection terminal of an extended lead. It is arranged on the seat back side from the vehicle body side. Specifically, the first connector is arranged to penetrate into the interior of a headrest pillar, which is arranged to fix the headrest on the seat back. The headrest pillar is formed to penetrate into the interior like a tube, and the first connector is held at its mouth (opening on the lower end side). On the other hand, the second connector is arranged at the lower part of the headrest support member inserted into and holding the headrest pillar, and is held by a retainer fixed integrally with the seat back. Therefore, the second connector is in a standby state, that is, when the headrest pillar is subsequently inserted into the headrest support member, the second connector is ready to be connected to the first connector held at the nose of the headrest pillar. Here, the second connector is configured to disengage from the retainer when pushed by the insertion force of the headrest stay after the insertion operation of the headrest stay, thereby connecting the first connector to the second connector.

[0006] US patent application US10569685B2 discloses a vehicle seat equipped with a seat back having a mounting portion, a headrest having a headrest frame and electronic components, a first connector and a second connector. The first connector has a coupling portion that engages with a hole in the headrest frame, a protrusion that engages with a second connector, and a first connector terminal electrically connected to a lead of the electronic component. The second connector has a first coupling piece that engages with the hole of the guide bracket from the outside of the guide bracket, a second coupling piece that engages with the protrusion of the first connector from the outside of the first connector, and an electrically connected second connector terminal. Connected to the lead wires wired in the seat back and the first connector terminal. The engagement of the hole of the mounting portion with the first engaging piece of the second connector can be irreversibly released.

[0007] There is a problem in the above prior art, that is, the headrest cannot be fully unplugged and replugged freely in the vehicle state (without disassembling the seat back). In addition, the male connector of the above prior art is easily damaged on the headrest guide rod. In addition, in the above prior art, the male connector cannot be fixed during seat production, which is not convenient for stable electrical connection after plugging and unplugging.

After the female end 1 continues to be inserted into the male end 2, the third protrusion 14 on the side of the male end 2 is engaged with the second card groove 6 to fix the two, completing the insertion. The side of the male end 2 is further clamped by the first spring piece 7 to further stabilize the insertion.

[0044] At the same time, a fourth protrusion 18 is provided on the side surface of the first rib 15 .

[0045] And fourth slots 19 are provided on both sides of the sleeve 4, and second spring pieces 20 are fixed inside the fourth slots 19. The second spring pieces 20 are in contact with the bottom of the first slot 3 at the ends away from the fourth slots 19. Second slide grooves 24 are symmetrically provided on the inner wall of the sleeve 4. A third rib 21 integrally formed with the sleeve 4 is provided between the two second slide grooves 24. A fifth protrusion 22 is fixed on the inner wall of the third rib 21. A sixth protrusion 23 fixed on the inner wall of the third rib 21 is provided above the fifth protrusion 22. The fifth protrusion 22 is engaged with the fourth protrusion 18, and the sixth protrusion 23 is in contact with the top of the extended protrusion block 17.

[0047] The working principle of this utility model:

[0048] Plug-in: At this time, the male end 2 is fixed inside the sleeve 4, and the headrest fixing metal rod 102 carries the female end 1 to move downward. When the female end 1 contacts the male end 2, it begins to plug with the male end 2. Since the male end 2 is a T-shaped structure, its size toward the female end 1 is small. Therefore, when entering the female end 1, it does not receive the downward pushing force of the female end 1. After the male end 2 and the female end 1 pass through the corresponding positions of the first rib 15 and the first slide groove 10, the female end 1 continues to be plugged in until the male end 2 enters. The third protrusion 14 on the side of the male end 2 is engaged with the second card groove 6 to fix the two to complete the plug-in. After the plug-in is completed, the headrest fixing metal rod 102 is in its highest position. When adjusting, it is adjusted downward, and at this time the male end 2 and the female end 1 are in a plug-in state. Therefore, during the adjustment process of the headrest fixing metal rod 102, the male end 2 and the female end 1 can be carried to move synchronously.

[0049] Pulling out: When the headrest fixing metal rod 102 is pulled out, the male end 2 can be moved upward synchronously with the female end 1. As the male end 2 moves into the interior of the sleeve 4, it is clamped and fixed by the fifth protrusion 22 and continues to move. When the extended protrusion block 17 of the male end 2 contacts the sixth protrusion 23 inside the sleeve 4, the male end 2 is restricted from moving and then stays inside the sleeve 4. At this time, the headrest fixing metal rod 102 can be pulled out, and the male end 2 can be conveniently plugged in next time after staying.

[0050] In this embodiment, the elastic clamping structure between the headrest fixing metal rod and the connecting sleeve is a conventional structure in the art and is not described in the present utility model.

[0051] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations.
