The headrest rod 2 is configured to connect with a guide sleeve 18 inside the car seat. The pluggable electrical connection structure 23 is disposed within the headrest rod 2 and the guide sleeve 18, and includes:

[0041] The first electrical connection assembly is disposed inside the headrest rod 2. The first electrical connection assembly includes a first connector 5, which has a first connection end and a second connection end. The first connection end is connected to a first wire 3. The interior of the first connector 5 is hollow, and the second connection end has a first opening and extends out of the headrest rod 2.

[0043] When the headrest rod 2 extends into the guide sleeve 18, the first connector 5 and the second connector 10 are electrically connected.

[0044] In this embodiment, as shown in Figures 1-2, two headrest rods 2 are provided at the bottom of the headrest body 1 to ensure the stability of the headrest installation; therefore, two guide sleeves 18 are provided inside the car seat corresponding to the headrest rods 2; the headrest rods 2 and the guide sleeves 18 are provided in a one-to-one correspondence.

[0045] Of course, in other embodiments, the bottom of the headrest body 1 is provided with one, three or four headrest rods 2, and the number of headrest rods 2 and guide sleeves 18 are the same and they are set one to one.

[0046] In this embodiment, as shown in Figures 3, 6 and 7, the first connector 5 is a female connector and the second connector 10 is a male connector. The male and female connectors form a physical connection between the first wire 3 and the second wire 4 to realize the transmission of electrical energy and the transmission of signals.

[0047] Specifically, in this embodiment, the first connector 5 is a cylindrical structure, and four placement slots 6 are provided around the first connector 5, with a spring piece 7 placed in each placement slot 6.

[0048] Specifically, the second connector 10 is provided with multiple copper electrodes; when the headrest body 1 is inserted into the guide sleeve 18, the fourth connection end extends into the first connector 5 through the first opening. At this time, the multiple copper electrodes contact the spring 7 to realize the transmission of current and signal between the first wire 3 and the second wire 4, thereby powering the devices inside the headrest.

[0049] Specifically, the elastic design of the spring 7 causes it to deform elastically when the second connector 10 is inserted, thereby generating a holding force and maintaining the tightness of the connection; as shown in Figure 7, the lengths of the spring 7 are not uniform to improve the stability of the electrical connection after insertion.

[0050] In some embodiments, as shown in Figures 9-10, a heating module 20 is provided inside the headrest body 1. The end of the first wire 3 away from the first connector 5 is connected to the heating module 20, and the end of the second wire 4 away from the first connector 5 is connected to the power supply module in the car seat to supply power to the heating module 20.

[0051] In some embodiments, as shown in FIG11, a ventilation module 21 or an audio system may also be provided inside the headrest body 1; both of which are connected to the first wire 3.

[0052] In some embodiments, the headrest rod 2 is provided with a first interface, and the end of the first wire 3 away from the first connector 5 is electrically connected to the first interface; at this time, the first interface is connected to an external power supply to power the electrical equipment.

[0053] In some embodiments, the headrest body 1 is provided with a first power connection component, which is connected to a first wire 3; at the same time, the headrest body 1 is provided with a soft pillow, which is provided with a heating module 20, a ventilation module 21 or an audio device, etc. The soft pillow is provided with a second power connection component, which is connected to the device, and the first power connection component and the second power connection component are electrically connected to each other to provide power to the device.

[0054] It is understood that the working principle of the pluggable electrical connection structure for a car seat headrest proposed in this embodiment is as follows: When installing the headrest on the car seat, the headrest body 1 is placed on top of the car seat backrest, and the headrest rod 2 is aligned with the guide sleeve 18. Then, the headrest rod 2 is inserted into the corresponding guide sleeve 18, so that the headrest rod 2 is connected to the guide sleeve 18. At this time, the fourth connection end of the second connector 10 extends into the interior of the first connector 5 from the second connection end. At this time, the second connector 10 contacts the spring 7 to supply power to the devices inside the headrest. It can be seen that this disclosure makes an electrical connection between the headrest and the car seat through a built-in electrical connection component. During the insertion and removal of the headrest rod 2, the first electrical connection component and the second electrical connection component can be disassembled and assembled, which is convenient and simple to connect and disassemble. At the same time, the electrical connection component is set inside the headrest rod 2 and the car seat, which is not easily damaged by environmental factors, ensuring the reliability of the electrical connection.

[0055] In an optional embodiment, the first electrical connection assembly further includes a first outer sleeve 8, which is fitted over the outside of the second connection end.

[0058] Specifically, the first electrical connection assembly also includes a first protective sleeve 9, which is fitted over the outside of the first connection end and is fixedly connected to the first outer sleeve 8, so that the first protective sleeve 9 and the first outer sleeve 8 together completely cover the first connector 5 to protect the first connector 5; at the same time, the first wire 3 passes through the first protective sleeve 9 and connects to the first connection end, so that the first protective sleeve 9 protects the connection position between the first wire 3 and the first connection end.

[0059] In this embodiment, the first protective sleeve 9 is sleeved on the outside of the first connecting end, and the first protective sleeve 9 is tightly attached to the spring piece 7 in the placement groove 6 located on the outer wall of the first connector 5 to fix the spring piece 7; optionally, the first protective sleeve 9 is made of rubber, silicone or soft plastic.

[0060] In an alternative embodiment, the second electrical connection assembly further includes a second jacket 11, which is sleeved on the outside of the second connector 10 and configured to snap into the first jacket 8.

[0061] Specifically, as shown in Figure 4, the second electrical connection assembly also includes a second outer sleeve 11, which is sleeved on the outside of the second connector 10. The second outer sleeve 11 is configured to protect and fix the second connector 10, and when the first connector 5 and the second connector 10 are connected, the second outer sleeve 11 engages with the first outer sleeve 8 to improve the stability of the connection between the first connector 5 and the second connector 10.

[0062] In an optional embodiment, the second electrical connection assembly further includes a second protective sleeve 12, which is sleeved on the outside of the third connection end. The second protective sleeve 12 is connected to the second outer sleeve 11, and the second wire 4 passes through the second protective sleeve 12 and is connected to the third connection end. The second protective sleeve 12 is configured to protect the connection position between the second wire 4 and the third connection end.

[0063] Specifically, the second electrical connection assembly also includes a second protective sleeve 12, which is sleeved on the outside of the third connection end. The second protective sleeve 12 is connected to the second outer sleeve 11 and is configured to protect and fix the second connector 10. The second wire 4 passes through the second protective sleeve 12 and is connected to the third connection end, so that the second protective sleeve 12 protects the connection position of the second wire 4 and the third connection end and prevents the second wire 4 from separating from the third connection end.

[0064] In this embodiment, the second protective sleeve 12 is provided with a fifth snap-fit ​​part 22 on its outside, and the second outer sleeve 11 is provided with a corresponding sliding groove 24. The fifth snap-fit ​​part 22 is connected to the sliding groove 24 to realize the connection between the second protective sleeve 12 and the second outer sleeve 11. In this embodiment, as shown in FIG8, the fifth snap-fit ​​part 22 is a protrusion.

[0065] In an alternative embodiment, a cushioning elastic element 13 is fitted onto the end of the second outer jacket 11 that is away from the first outer jacket 8.

[0066] Specifically, the end of the second outer sleeve 11 away from the first outer sleeve 8 is fitted with a buffer elastic element 13; when the headrest is installed on the car seat, the headrest rod 2 is inserted into the guide sleeve 18, thereby driving the first electrical connection assembly and the second electrical connection assembly to move to the bottom of the guide sleeve 18. At this time, the buffer elastic element 13 abuts against the bottom of the guide sleeve 18 to play a buffering role and prevent the first electrical connection assembly and the second electrical connection assembly from being damaged.

[0067] Optionally, the buffer elastic element 13 is a spring, high-elasticity sponge, sheet, or other elastic structure or material.

[0068] In an optional embodiment, the second outer sleeve 11 is provided with a second limiting part 15. When the headrest is removed, the headrest body 1 is moved upward along with the headrest rod 2. When the second limiting part 15 abuts against the end of the guide sleeve 18 near the headrest body 1, the second connector 10 is limited and no longer moves. At this time, the first connector 5 continues to move upward with the headrest rod 2. At this time, the first electrical connection component and the second electrical connection component are separated, and the removal of the headrest body 1 is completed.

[0069] In this embodiment, the second limiting part 15 is a protrusion with two protrusions respectively disposed on both sides of the second outer sleeve 11 to limit the second connector 10; at the same time, using a single protrusion as the second limiting part 15 to limit the second connector 10 reduces the contact area between the second outer sleeve 11 and the guide sleeve 18 and avoids generating friction noise.

[0070] In an optional embodiment, the first outer sleeve 8 is provided with at least one first snap-fit ​​portion 16, which is located on the side of the first limiting portion 14 near the first guide wire 3; the inner wall of the headrest rod 2 is provided with a second snap-fit ​​portion corresponding to the first snap-fit ​​portion 16, and the first snap-fit ​​portion 16 is configured to snap into the second snap-fit ​​portion.

[0071] In this embodiment, as shown in FIG5, a first snap-fit ​​portion 16 is provided on the first outer sleeve 8. The first snap-fit ​​portion 16 is a protrusion and is located on the side of the first limiting portion 14 near the first wire 3. A second snap-fit ​​portion is provided on the inner wall of the headrest corresponding to the first snap-fit ​​portion 16. The second snap-fit ​​portion is a groove. The first electrical connection component is disposed in the headrest rod 2, and the first snap-fit ​​portion 16 is snapped into the second snap-fit ​​portion to connect the first electrical connection component and the headrest rod 2, preventing the first electrical connection component from falling out of the headrest rod 2.

[0072] In this embodiment, the first snap-fit ​​part 16 is a groove, and the second snap-fit ​​part is a corresponding protrusion, and the first snap-fit ​​part 16 snaps into the second snap-fit ​​part.

[0073] In an optional embodiment, the first outer jacket 8 is provided with at least one third snap-fit ​​portion 17, which is located on the side of the first limiting portion 14 away from the first wire 3; the inner wall of the second outer jacket 11 is provided with a fourth snap-fit ​​portion 25 corresponding to the third snap-fit ​​portion 17; when the first outer jacket 8 is connected to the second outer jacket 11, the fourth snap-fit ​​portion 25 snaps into the third snap-fit ​​portion 17.

[0074] In this embodiment, a third latching part 17 is provided on the first outer jacket 8. The third latching part 17 is a protrusion and is located on the side of the first limiting part 14 away from the first wire 3. A fourth latching part 25 is provided on the inner wall of the second outer jacket 11 corresponding to the third latching part 17. The fourth latching part 25 is a groove. When the first electrical connection assembly and the second electrical connection assembly are connected, the second outer jacket 11 is inserted into the first outer jacket 8 to connect with the first outer jacket 8. At this time, the first latching part 16 and the third latching part 17 are latched to increase the stability of the connection between the first outer jacket 8 and the second outer jacket 11.

[0075] In some embodiments, the third latching portion 17 is a groove, and the fourth latching portion 25 is a corresponding protrusion, and the third latching portion 17 and the fourth latching portion 25 are latched together.

[0076] In an optional embodiment, the second outer sleeve 11 is further provided with a third limiting part 19, which is located on the side of the second limiting part 15 near the second guide wire 4, and the buffer elastic member 13 is fixedly connected to the third limiting part 19; the third limiting part 19 is configured to abut against the inner wall of the guide sleeve 18 to prevent the second connector 10 from shifting.

[0077] Specifically, as shown in Figures 4 and 7, the second outer sleeve 11 is also provided with a third limiting part 19. The third limiting part 19 is located on the side of the second limiting part 15 near the buffer elastic member 13. In this embodiment, the third limiting part 19 is a protrusion, and there are two protrusions respectively provided on both sides of the second outer sleeve 11 to limit the second connector 10 and prevent the second connector 10 from shifting inside the guide sleeve 18. At the same time, using a single protrusion as the third limiting part 19 to limit the second connector 10 reduces the contact area between the second outer sleeve 11 and the guide sleeve 18 and avoids friction noise.

[0078] Furthermore, the third limiting part 19 is also configured to connect with the buffer elastic member 13 to provide support for the buffer elastic member 13.
