Description

Technical Field

[0001] This application relates to the technical field of electrical connection structures for wire harnesses, and in particular to a conductive connection device and a vehicle seat. Background Technology

[0002] To improve the in-car audio effect, speakers are usually installed in the headrest. One end of the headrest speaker wiring harness is electrically connected to the speaker and fixed in the headrest support. When the headrest sub-assembly is inserted into the headrest guide sleeve, the other end of the wiring harness is electrically connected to the connector in the seat body. Due to the presence of the wiring harness and connector, the headrest cannot be completely pulled out of the seat. If the headrest is forcibly pulled out, the wiring harness and connector will be disconnected and cannot be reinstalled. Utility Model Content

[0003] Therefore, it is necessary to provide a conductive connection device and a vehicle seat to solve the problem that the wiring harness will disconnect from the connector and cause a power outage when the existing headrest is pulled out.

[0004] The conductive connection device provided in this application includes a guide sleeve, a wire harness, an electrical contact, and a conductive slide rail. The wire harness is electrically connected to the electrical contact, and the conductive slide rail is installed on the guide sleeve and extends along the axial direction of the guide sleeve. The electrical contact and the conductive slide rail slide in contact and engage along the axial direction of the guide sleeve, so that the wire harness can extend into or out of the guide sleeve. The electrical contact can apply pressure to the conductive slide rail, so that the electrical contact and the conductive slide rail can maintain an electrical connection during sliding.

[0005] In one embodiment, the conductive connection device further includes an adapter through which the wire harness is electrically connected to the electrical contact, or the wire harness is directly electrically connected to the electrical contact.

[0006] In one embodiment, the electrical contact includes a mounting section and an elastic contact section. The electrical contact is mounted on the adapter via the mounting section. One end of the elastic contact section is connected to the adapter, and the other end is bent toward the direction close to the conductive slide rail. When the elastic contact section and the conductive slide rail are in contact, the elastic contact section can apply an elastic force to the conductive slide rail so that the elastic contact section and the conductive slide rail can maintain an electrical connection.

[0007] In one embodiment, the electrical contact includes a sleeve portion and an elastic pressure head. The electrical contact is sleeved on the outer periphery of the adapter through the sleeve portion. One end of the elastic pressure head is connected to the side wall of the sleeve portion, and the other end extends toward the direction close to the conductive slide rail. When the elastic pressure head and the conductive slide rail are in contact, the elastic pressure head can apply an elastic force to the conductive slide rail so that the elastic pressure head and the conductive slide rail can maintain an electrical connection.

[0008] In one embodiment, the electrical contact includes a connecting portion and a contact portion. The electrical contact is mounted on the adapter via the connecting portion. One end of the contact portion is connected to the adapter, and the other end protrudes toward the conductive slide rail. The contact portion and the conductive slide rail are interference-fitted so that the contact portion and the conductive slide rail can maintain an electrical connection.

[0009] In one embodiment, the adapter includes a conductive sheet and a mounting bracket, wherein the wiring harness is electrically connected to an electrical contact via the conductive sheet, and the electrical contact is mounted on the mounting bracket.

[0010] In one embodiment, the conductive connection device further includes a support post, the wire harness is disposed within the support post, and one or both of the adapter and the electrical contact are mounted on the support post, the support post being able to be inserted into or extend out of the guide sleeve.

[0011] In one embodiment, the conductive connection device further includes a limiting slide rail and a limiting block. The limiting slide rail is installed on the guide sleeve and extends along the axial direction of the guide sleeve. The limiting block is fixedly connected and protrudes from the outer peripheral wall of the support column. The support column can slide and engage along the axial direction of the guide sleeve through the limiting block and the limiting slide rail.

[0012] In one embodiment, the conductive slide rail extends continuously along the axial direction of the guide sleeve; or, the conductive slide rail includes multiple sub-rails, each of which extends along the axial direction of the guide sleeve, and the multiple sub-rails are distributed on the same straight line of the guide sleeve, so that the electrical contact can conduct the circuit of the conductive connection device through any one of the sub-rails.

[0013] This application also provides a vehicle seat, which includes a headrest, a backrest, and the conductive connection device described in any of the above embodiments. The headrest is installed on the backrest, the wiring harness is connected to a speaker inside the headrest, and the guide sleeve is installed on the backrest.

[0014] Compared to existing technologies, the conductive connection device and vehicle seat provided in this application not only enable the movement of the wiring harness and electrical contacts relative to the guide sleeve, facilitating the insertion or removal of the headrest from the backrest, but also ensure that the electrical contacts and the conductive slide rail maintain an electrical connection during movement through the pressure applied by the electrical contacts to the conductive slide rail. This prevents the headrest from failing to completely detach from the backrest or from experiencing power loss upon detachment. Furthermore, by extending the length of the conductive slide rail, the movement distance of the wiring harness relative to the guide sleeve can be increased. Attached Figure Description

[0019] To improve the in-car audio effect, speakers are usually installed in the headrest. One end of the headrest speaker wiring harness is electrically connected to the speaker and fixed in the headrest support. When the headrest sub-assembly is inserted into the headrest guide sleeve, the other end of the wiring harness is electrically connected to the connector in the seat body. Due to the presence of the wiring harness and connector, the headrest cannot be completely pulled out of the seat. If the headrest is forcibly pulled out, the wiring harness and connector will be disconnected and cannot be reinstalled.

[0020] Please see Figure 1 and Figure 2 To address the issue of power loss caused by the disconnection of the wiring harness and connector after the existing headrest is removed, this application provides a conductive connection device and a vehicle seat. The conductive connection device includes a guide sleeve 100, a wiring harness 200, an adapter 300, an electrical contact 400, and a conductive slide rail 500. The wiring harness 200 is connected to a speaker (not shown) inside the headrest (not shown), the guide sleeve 100 is mounted on the backrest (not shown), and the electrical contact 400 is mounted on the adapter 300.

[0021] It should be noted that the wire harness 200, adapter 300, electrical contact 400 and conductive slide rail 500 are all divided into positive and negative poles, and are not specified separately here.

[0022] It should be noted that the guide sleeve 100 can be an independent component and detachably connected to the backrest, or the guide sleeve 100 can be fixedly connected to a component inside the backrest.

[0023] In one embodiment, such as Figure 1 and Figure 2As shown, the conductive connection device also includes a support post 600, with the wire harness 200 disposed within the support post 600. One or both of the adapter 300 and the electrical contact 400 are mounted on the support post 600. The support post 600 can be inserted into or extend from the guide sleeve 100. That is, either one of the adapter 300 and the electrical contact 400 can be mounted on the support post 600, or both can be mounted on the support post 600.

[0024] Typically, the wiring harness 200 is a flexible structure, while the support column 600 is a rigid structure. Therefore, by arranging the support column 600 and the guide sleeve 100 in a movable fit, the headrest and backrest can fit more smoothly. Furthermore, the wiring harness 200 is housed within the support column 600, preventing the wiring harness 200 from being exposed and accumulating dust or water, thus effectively improving the sealing performance of the wiring harness 200.

[0025] However, this is not the only embodiment. In other embodiments, the wiring harness 200 may also be wrapped around the outside of the support column 600 to reduce installation difficulty.

[0026] Furthermore, in one embodiment, the conductive connection device further includes a limiting slide rail (not shown) and a limiting block (not shown). The limiting slide rail is installed on the guide sleeve portion 100 and extends along the axial direction of the guide sleeve portion 100. The limiting block is fixedly connected and protrudes from the outer peripheral wall of the support column 600. The support column 600 can slide and engage along the axial direction of the guide sleeve portion 100 through the limiting block and the limiting slide rail.

[0027] This design prevents the support column 600 and the guide sleeve 100 from rotating relative to each other, which would cause the conductive slide rail 500 and the electrical contact 400 to lose contact. In other words, it improves the stability of the fit between the conductive slide rail 500 and the electrical contact 400.

[0028] The wire harness 200 is electrically connected to the electrical contact 400 via the adapter 300, and the conductive slide rail 500 is mounted on the guide sleeve 100 and extends along the axial direction of the guide sleeve 100.

[0029] Specifically, in one embodiment, such as Figure 2 As shown, the conductive slide rail 500 extends continuously along the axial direction of the guide sleeve portion 100.

[0030] This design makes the connection between the electrical contact 400 and the conductive slide rail 500 smoother.

[0031] In another embodiment, the conductive slide rail 500 includes multiple sub-rails (not shown), each sub-rail extending along the axial direction of the guide sleeve portion 100, and the multiple sub-rails are distributed on the same straight line of the guide sleeve portion 100, and the electrical contact 400 can conduct the circuit through any one of the sub-rails.

[0032] It should be noted that each rail can be electrically connected to the circuit components inside the backrest, or adjacent rails can be electrically connected, with one rail being electrically connected to the circuit components inside the backrest.

[0033] With this configuration, when the headrest has multiple positions, the electrical contact 400 can be positioned at different points on the track.

[0034] The electrical contact 400 and the conductive slide rail 500 slide and engage along the axial direction of the guide sleeve 100, allowing the wire harness 200 to extend into or out of the guide sleeve 100, thereby facilitating the insertion or removal of the headrest from the backrest. Furthermore, the electrical contact 400 can apply pressure to the conductive slide rail 500, ensuring that the electrical contact 400 and the conductive slide rail 500 remain electrically connected during sliding. In other words, the wire harness 200 is ultimately electrically connected to the circuit components inside the backrest via the adapter 300, the electrical contact 400, and the conductive slide rail 500 in sequence.

[0035] It should be noted that the conductive slide rail 500 and the circuit components inside the backrest can be connected by plugs or soldered.

[0036] Furthermore, it should be noted that the wire harness 200 can also be directly electrically connected to the electrical contact 400, specifically by soldering, snap-fitting, or fastener connection.

[0037] In this way, not only can the wire harness 200 and the electrical contact 400 move relative to the guide sleeve 100 to facilitate the insertion or removal of the headrest from the backrest, but also, during the movement, the pressure applied by the electrical contact 400 to the conductive slide rail 500 ensures that the electrical contact 400 and the conductive slide rail 500 maintain an electrical connection during sliding, thus preventing the headrest from failing to completely detach from the backrest or from losing power upon detachment. Furthermore, by extending the length of the conductive slide rail 500, the movement distance of the wire harness 200 relative to the guide sleeve 100 can be increased.

[0038] In one embodiment, such as Figure 2 As shown, the electrical contact 400 includes a mounting section 410 and an elastic contact section 420. The electrical contact 400 is mounted on the adapter 300 through the mounting section 410. One end of the elastic contact section 420 is connected to the adapter 300, and the other end is bent towards the conductive slide rail 500. When the elastic contact section 420 and the conductive slide rail 500 are in contact, the elastic contact section 420 can apply an elastic force to the conductive slide rail 500 so that the elastic contact section 420 and the conductive slide rail 500 can maintain an electrical connection.

[0039] This configuration not only improves the installation strength of the electrical contact 400, but also enhances the supporting force of the electrical contact 400 through the adapter 300, thereby improving the contact effect between the electrical contact 400 and the conductive slide rail 500.

[0040] Furthermore, in one embodiment, the mounting section 410 and the elastic contact section 420 are integrally bent and formed.

[0041] This design can greatly enhance the elastic force of the elastic contact section 420 and improve the structural strength of the electrical contact 400.

[0042] However, this is not the only option. In other embodiments, the mounting section 410 and the resilient contact section 420 may also be welded.

[0043] It should be noted that the electrical contact 400 can be a metal part, or it can be made of conductive polymer materials or other materials.

[0044] In another embodiment, the electrical contact 400 includes a sleeve portion (not shown) and an elastic pressure head (not shown). The electrical contact 400 is sleeved on the outer periphery of the adapter 300 through the sleeve portion so that the electrical contact 400 is mounted on the adapter 300. One end of the elastic pressure head is connected to the side wall of the sleeve portion, and the other end extends toward the direction close to the conductive slide rail 500. When the elastic pressure head and the conductive slide rail 500 are in contact, the elastic pressure head can apply an elastic force to the conductive slide rail 500 so that the elastic pressure head and the conductive slide rail 500 can maintain an electrical connection.

[0045] This design not only improves the ease of installation of the electrical contact 400, but also enhances the supporting force of the electrical contact 400 through the adapter 300, thereby improving the contact effect between the electrical contact 400 and the conductive slide rail 500.

[0046] Furthermore, in one embodiment, the elastic pressure head and the sleeve portion are integrally formed, and the elastic pressure head is formed by cutting and bending the outer periphery of the sleeve portion through a metal cutting process.

[0047] However, this is not the only embodiment. In other embodiments, the elastic pressure head can also be directly welded to the outer wall of the sleeve.

[0048] In another embodiment, the electrical contact 400 includes a connecting portion (not shown) and a contact portion (not shown). The electrical contact 400 is mounted on the adapter 300 via the connecting portion. One end of the contact portion is connected to the adapter 300, and the other end protrudes toward the conductive slide rail 500. Furthermore, the contact portion and the conductive slide rail 500 are interference-fitted so that the contact portion and the conductive slide rail 500 can maintain an electrical connection.

[0049] With this design, the contact part is less likely to experience elastic failure, which means that the fatigue life of the electrical contact 400 can be improved.

[0050] In one embodiment, such as Figure 2 As shown, the adapter 300 includes a conductive sheet 310 and a mounting bracket 320. The wire harness 200 is electrically connected to the electrical contact 400 through the conductive sheet 310, and the electrical contact 400 is mounted on the mounting bracket 320.

[0051] This design greatly improves the connection strength between the electrical contact 400 and the adapter 300.

[0052] Furthermore, in one embodiment, the conductive sheet 310 and the electrical contact 400 are integrally bent or welded together.

[0053] More specifically, when the conductive sheet 310 and the electrical contact 400 are welded together, the conductive sheet 310 may be welded only to the electrical contact 400, or it may be welded to the electrical contact 400 on the basis of being mounted on the mounting bracket 320.

[0054] Furthermore, in one embodiment, as Figure 2 As shown, the mounting bracket 320 is an injection molded part, and the electrical contact 400 is embedded in the mounting bracket 320, or the electrical contact 400 is snapped into the mounting bracket 320.

[0055] This design prevents leakage of the mounting bracket 320 and improves the assembly strength of the electrical contact 400 and the mounting bracket 320.

[0056] Specifically, the mounting bracket 320 is cylindrical, and the mounting bracket 320 and the guide sleeve 100 are coaxially arranged.

[0057] Furthermore, in one embodiment, as Figure 2 As shown, the conductive connection device also includes a terminal block 700, one end of which is connected to the wire harness 200, and the other end of which can be plugged into the conductive sheet 310.

[0058] This configuration greatly improves the connection flexibility of the wiring harness 200 and the adapter 300.

[0059] However, this is not the only embodiment. In other embodiments, the conductive sheet 310 can also be directly soldered to the wire harness 200.

[0060] This application also provides a vehicle seat, which includes a headrest, a backrest, and the conductive connection device described in any of the above embodiments. The headrest is installed on the backrest, the wiring harness 200 is connected to a speaker inside the headrest, and the guide sleeve 100 is installed on the backrest.
