Description

Technical Field

[0001] This utility model belongs to the field of automotive parts technology, and in particular relates to a functional headrest quick-connect device. Background Technology

[0002] After the existing car headrest rod is inserted into place, the wires need to be connected in series manually, which is slow, time-consuming and labor-intensive, and easy to connect the wrong wires, which may cause short circuits.

[0003] For example, patent application number CN202320154992.8 describes a fixing mechanism for a headrest support rod and a music headrest, comprising: a main frame; a support rod mounting part disposed on the main frame, the support rod mounting part having: a guide part and a mounting part coaxially disposed and a locking part; a support rod, one end of which passes through the guide part and is fixed in the mounting part, the support rod having a first snap-fit ​​groove; and a fixing member, which passes through the locking part and is fixed in the first snap-fit ​​groove. However, the disadvantage of this technical solution is that after the support rod is inserted into place, the wires need to be manually connected in series, which is slow, time-consuming and laborious, and prone to incorrect wiring, posing a risk of short circuit.

[0031] Example 1

[0032] like Figures 1-10 As shown, a functional headrest quick-connect device includes a headrest rod 1, a female connector 2 fixedly installed at the lower end of the headrest rod 1, the headrest rod 1 being inserted into a housing assembly, a male connector 8 being slidably connected inside the housing assembly, the male connector 8 being inserted into the female connector 2, and two elastic metal pieces 7 being installed inside the housing assembly, the two elastic metal pieces 7 being slidably connected to both ends of the male connector 8 respectively.

[0033] The working principle of the above technical solution is as follows: The upper end of the headrest rod 1 is connected to the car headrest. The housing assembly is fixed inside the car seat back. The car headrest is inserted into the housing assembly through the headrest rod 1. The female connector 2 contacts and inserts into the male connector 8. The female connector 2 squeezes the male connector 8 and moves it downward inside the housing assembly. The two ends of the male connector 8 contact two elastic metal pieces 7. Under the support of the two elastic metal pieces 7, the female connector 2 and the male connector 8 are inserted into place. As the headrest rod 1 continues to be inserted into the housing assembly, the male connector 8 squeezes the two elastic metal pieces 7 and deforms. The male connector 8 moves downward to the bottom inside the housing assembly. The female connector 2 squeezes the male connector 8 to the bottom of the housing assembly, further ensuring that the female connector 2 and the male connector 8 are inserted into place. Under the action of the two elastic metal pieces 7, the female connector 2 and the male connector 8 can be inserted into place as soon as the headrest rod 1 is inserted into the housing assembly, realizing circuit connection. The female connector 2 and the male connector 8 are convenient and quick to insert, without the need for manual circuit connection, saving time and effort.

[0034] Example 2

[0035] like Figures 1-10 As shown, the housing assembly includes a sleeve 3, the headrest rod 1 is inserted into the sleeve 3, and the sleeve 3 is inserted into and fixed in the headrest quick-release upper shell 4;

[0036] The headrest quick-connect upper shell 4 and the headrest quick-connect lower shell 5 are fixedly installed by screw 6. The connector male end 8 slides inside the headrest quick-connect lower shell 5. Both elastic metal pieces 7 are installed inside the headrest quick-connect lower shell 5.

[0037] The lower end of the headrest quick-connect lower shell 5 is fixedly installed to the headrest quick-connect base 9 by two screws 10.

[0038] The working principle of the above technical solution is as follows: the sleeve 3 ensures that the headrest rod 1 will not wobble after being inserted into place, thus ensuring the stability of the car headrest. It is fixed by screw 6 and screw 10, which facilitates the installation and disassembly of various parts and makes maintenance convenient.

[0039] Example 3

[0040] like Figures 1-10 As shown, the male connector 8 includes a male connector body 801, which slides inside the headrest quick-connect lower shell 5. A cylindrical terminal 802 is fixed inside the male connector body 801, and the upper end of the cylindrical terminal 802 is connected to the plug 803. The plug 803 is inserted into the female connector 2.

[0041] Both ends of the connector male end body 801 are equipped with elastic metal sheets 804. The upper ends of the two elastic metal sheets 804 are respectively engaged in the square holes 13 provided on both sides of the headrest rod 1, and the lower ends of the two elastic metal sheets 804 are respectively slidably connected to the two protrusions 14 provided in the headrest quick-insertion lower shell 5.

[0042] Both ends of the male connector body 801 are provided with protrusions 805, and the two protrusions 805 are respectively slidably connected to two elastic metal sheets 7.

[0043] The headrest quick-connect base 9 includes a base body 901, which is fixed to the lower end of the headrest quick-connect lower shell 5 by two screws 10.

[0044] The base body 901 is provided with a rubber pad 902, and the lower end of the connector male end body 801 abuts against the rubber pad 902. Both the base body 901 and the rubber pad 902 are provided with a round hole 903 at their center positions.

[0045] The female end 2 of the connector is connected to the female end wire harness 11 of the headrest rod passing through the headrest rod 1, and the lower end of the cylindrical terminal 802 is connected to the male end wire harness 12 of the headrest rod.

[0046] The number of sections in both the female connector 2 and the plug 803 is 4-8.

[0047] The working principle of the above technical solution is as follows: The headrest rod 1 is inserted into the sleeve 3, and the lower end of the headrest rod 1 is inserted into the headrest quick-connect lower shell 5. The female connector 2 is connected to the plug 803. The female connector 2 continues to move down, squeezing the male connector body 801 to slide down in the headrest quick-connect lower shell 5. When the protrusions 805 at both ends of the male connector body 801 abut against the two elastic metal pieces 7, the two elastic metal pieces 7 provide a certain support force to the male connector body 801, so that the female connector 2 and the plug 803 are connected in place. The upper ends of the two elastic metal pieces 804 are engaged in the two square holes 13, ensuring the stability of the connection between the female connector 2 and the plug 803. The functional devices in the car headrest are connected to the car's internal power supply through the headrest rod female end wiring harness 11, the female connector 2, the plug 803, the cylindrical terminal 802, and the headrest rod male end wiring harness 12, so as to realize the connection and power supply of the functional devices in the car headrest.

[0048] Continue inserting the headrest rod 1 into the headrest quick-connect lower shell 5. The connector male end body 801 deforms by pressing the two elastic metal pieces 7. The connector male end body 801 moves down past the two elastic metal pieces 7. The connector female end 2 presses the connector male end body 801 onto the rubber pad 902 inside the base body 901, further ensuring that the connector female end 2 and the plug 803 are properly inserted. The rubber pad 902 plays a shock-absorbing and buffering role for the connector male end body 801.

[0049] When the headrest rod 1 needs to be pulled out, the headrest rod 1 is pulled outward. The female end of the connector 2 drives the male end body 801 of the connector to move upward through the two elastic metal sheets 804. When the lower ends of the two elastic metal sheets 804 contact the two protrusions 14 provided in the lower shell 5 of the headrest quick insert, the two protrusions 14 squeeze the lower ends of the two elastic metal sheets 804 together and move. The upper ends of the two elastic metal sheets 804 open outward, causing the upper ends of the elastic metal sheets 804 to separate from the two square holes 13, so that the female end of the connector 2 can be separated from the plug 803.

[0050] The female connector 2 and the male connector 8 can be easily and quickly plugged in and out. The current or signal can be quickly switched on or off by inserting or removing the headrest rod 1.
