[0025] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

[0026] like Figures 1 to 6 As shown, in this solution, the application of the quick-plug power-on mechanism in automobiles and the specific structure of the quick-plug power-on mechanism are mainly described in detail.

[0027] A quick-insert electrification mechanism for a car headrest is used to connect a headrest support rod and a car seat, comprising a connector 1, a guide sleeve 4, and a fixing piece.

[0028] Specifically, the connecting member 1 is connected to the headrest support rod 3, and the connecting member 1 includes a first conductive contact 2 on the outside; the guide sleeve 4 is connected to the car seat, and is used for inserting and fixing the headrest support rod 3 into and fixing the headrest support rod 3. The guide sleeve 4 is provided with a second conductive contact 5 at the end along the insertion path of the headrest support rod 3, and the end of the guide sleeve 4 has an expanded state and a retracted state; the fixing member is connected to the guide sleeve 4, and is used to drive the end of the guide sleeve 4 to switch from the expanded state to the retracted state; when the end of the guide sleeve 4 switches from the expanded state to the retracted state, it is used for the second conductive contact 5 to press against the first conductive contact 2.

[0029] In this embodiment, the first conductive contact 2 is electrically connected to the playback device on the vehicle headrest, while the second conductive contact 5 on the guide sleeve 4 is electrically connected to the vehicle power supply. The playback device can be an audio device, a massage device, or a video playback device. During installation, the connector 1 with the first conductive contact 2 is first mounted on the headrest support rod 3. The headrest support rod 3 with the connector 1 is then inserted into the guide sleeve 4. Before installation, the end of the guide sleeve 4 is in an extended state. During the connection process between the headrest support rod 3 and the guide sleeve 4, the fixing member is first fixed to the end of the guide sleeve 4, causing the end to be retracted. When the headrest support rod 3 is fully inserted, the first conductive contact 2 and the second conductive contact 5 are in close contact, thereby powering the playback device on the vehicle headrest. To remove the vehicle headrest from the vehicle seat, the guide sleeve 4 should first release the lock on the vehicle headrest. Then, a certain force should be applied to the vehicle headrest to separate the first conductive contact 2 and the second conductive contact 5. Finally, the vehicle headrest should be pulled out to complete the separation from the vehicle seat. It is worth noting that the locking mechanism between the guide sleeve 4 and the headrest support rod 3 belongs to the scope of the existing technology and will not be described in detail here.

[0030] The core of this solution lies in installing a connector 1 with a first conductive contact 2 on a headrest support rod 3 and providing a second conductive contact 5 at the end of a guide sleeve 4 along the insertion path of the headrest support rod 3. The fixing member allows the end of the guide sleeve 4 to transition from an open position to a retracted position, ensuring close contact between the first conductive contact 2 and the second conductive contact 5. This not only ensures power to the headrest playback device but also ensures that the headrest can be easily removed from the car seat, fully satisfying passengers' demand for flexible headrest use.

[0031] In one embodiment, the end of the guide sleeve 4 includes a plurality of connecting portions 7 spaced apart along the circumferential direction of the guide sleeve 4, and the fixing member is clamped on the plurality of connecting portions 7 to drive the plurality of connecting portions 7 to converge toward the center line direction of the guide sleeve 4, so as to switch the end of the guide sleeve 4 to a retracted state.

[0032] In this embodiment, there are preferably six connecting portions 7, which are evenly spaced at the end of the guide sleeve 4. When the fixing member pushes the end of the guide sleeve 4 to switch to the retracted state, each connecting portion 7 is brought together toward the centerline of the guide sleeve 4. This spaced arrangement leaves a gap between each adjacent connecting portion 7, making it easier for the connecting portions 7 to be brought together under the action of the fixing member.

[0033] Preferably, the fixing member is a first elastic clip 6 .

[0034] In one embodiment, the guide sleeve 4 is made of plastic and is integrally formed with the second conductive contact 5 or separately provided.

[0035] The guide sleeve 4 is made of plastic and is integrally molded with the second conductive contact 5. Specifically, the second conductive contact 5 is secured within the mold before the guide sleeve 4 is formed. During the molding process, the molten material envelops the second conductive contact 5. After the guide sleeve 4 solidifies, the second conductive contact 5 is securely attached to the guide sleeve 4. Alternatively, the guide sleeve 4 and second conductive contact 5 can be separately secured, for example, by threading, gluing, or welding.

[0036] In one embodiment, a groove 8 is provided at the connecting end of the headrest support rod 3 and the connecting member 1 , and a second elastic retaining spring 9 is provided in the groove 8 . The second elastic retaining spring 9 is used to fix the connecting member 1 on the headrest support rod 3 .

[0037] In one embodiment, a positioning groove 10 is provided on the headrest support rod 3, and both sides of the positioning groove 10 along the axis direction of the headrest support rod 3 are inclined surfaces. The connecting member 1 is provided with an extension section 11 inserted into the headrest support rod 3, and the extension section 11 is provided with a positioning block 12 adapted to the positioning groove 10. The positioning block 12 is inserted into the positioning groove 10 to provide positioning for the connection between the connecting member 1 and the headrest support rod 3.

[0038] The extension section 11 is provided to make the connection between the headrest support rod 3 and the connecting member 1 tighter, and the positioning groove 10 and the positioning block 12 are provided to enable the first conductive contact 2 fixed on the headrest support rod 3 through the connecting member 1 to be aligned with the second conductive contact 5 on the guide sleeve 4.

[0039] In one embodiment, the connector 1 and the first conductive contact 2 are integrally formed or separately provided.

[0040] The manner in which the connector 1 and the first conductive contact 2 are integrally formed or separately provided can refer to the manner in which the guide sleeve 4 and the first conductive contact 2 are connected, and will not be described in detail here.

[0041] In one embodiment, it also includes a first wire 13 and a second wire 14. One end of the first wire 13 extends into the headrest support 3 and is connected to the first conductive contact 2. One end of the second wire 14 is connected to the vehicle power supply, and the other end extends into the car seat and is connected to the second conductive contact 5.

[0042] The first wire 13 is used to connect the playback device on the car headrest and the first conductive contact 2 to realize power-on operation of the playback device.
