Description

Technical Field

[0001] The utility model belongs to the technical field of seat headrests and relates to a quick disassembly and assembly structure of a wire harness headrest. Background Art

[0002] At present, more and more mid-to-high-end car models are equipped with audio-visual systems on the car seat headrests. After the audio-visual systems are loaded, the seat headrests cannot be disassembled or moved during use due to the layout of circuit routing and wiring harness connections. Usually, professionals are required to use special tools to complete the disassembly and installation of the headrests, and the disassembly and installation process is relatively cumbersome, which affects the comfort of the seat when it is folded down in a small space, as well as the comfort and subsequent maintenance of the car seat headrests during use. Summary of the Invention

[0003] The purpose of the present invention is to solve the above problems in the existing technology and propose a quick disassembly and assembly structure of a headrest with a wiring harness. The technical problem to be solved by the present invention is how to achieve quick disassembly and assembly of a headrest with a wiring harness.

[0004] The purpose of this utility model can be achieved through the following technical solutions:

[0005] A quick-disassembly structure with a wiring harness headrest, the headrest including a guide sleeve and a headrest rod movably plugged into the guide sleeve, characterized in that the quick-disassembly structure includes a wiring harness female connector and a wiring harness male connector that are detachably connected up and down, the wiring harness female connector being arranged on the headrest rod, the wiring harness male connector being arranged on the guide sleeve and being movable along the length direction of the guide sleeve, the guide sleeve being provided with a guide hole along its length direction, the wiring harness male connector being provided with a guide block, and the guide block being embedded in the guide hole, a spring being provided between the wiring harness male connector and the inner wall of the guide sleeve, and under the action of the spring, the wiring harness male connector and the wiring harness female connector remain connected.

[0006] When the seat headrest is adjusted in height, the headrest rod moves up and down under the action of external force, and the female connector of the wiring harness can move up and down synchronously with the headrest rod, while the male connector of the wiring harness can move up and down synchronously with the female connector of the wiring harness under the action of the spring. At the same time, the matching structure of the guide block and the guide hole can guide the movement of the male connector of the wiring harness, so that the female connector of the wiring harness arranged on the headrest rod and the male connector of the wiring harness arranged on the guide sleeve can always remain connected, so that the height of the headrest can still be adjusted while ensuring the function of the audio-visual system. In addition, due to the limiting effect of the upper edge of the guide hole on the guide block on the male connector of the wiring harness, the wiring harness can be adjusted in time. After the male connector of the wiring harness moves upward to the highest position (i.e. the position where the guide block contacts the upper edge of the guide hole), the male connector of the wiring harness cannot move further upward, while the female connector of the wiring harness can continue to move upward with the headrest rod and disconnect from the male connector of the wiring harness. When the male connector of the wiring harness and the female connector of the wiring harness need to be reconnected, the user only needs to reinsert the headrest rod on the guide sleeve, and the female connector of the wiring harness can move downward synchronously with the headrest rod, and the spring can support the male connector of the wiring harness, so the female connector of the wiring harness can move downward with the headrest rod until it is connected with the male connector of the wiring harness, thereby realizing quick disassembly and assembly of the headrest with the wiring harness.

[0007] In the aforementioned quick-detachable headrest structure with a wiring harness, the headrest rod is cylindrical and has an L-shaped notch at its lower end. The wiring harness female connector has a protrusion that is embedded in the notch. This structure enables quick detachment of the wiring harness female connector and the headrest rod.

[0008] In the aforementioned quick-disassembly structure for a headrest with a wiring harness, the guide sleeve comprises a cylindrical guide sleeve body and a removable end cap disposed at the lower end of the guide sleeve body. The end cap has a clearance hole for the wiring harness to pass through. The lower end of the spring abuts against the inner wall of the end cap, and the upper end of the spring is sleeved onto the wiring harness male connector. This structure facilitates assembly and disassembly of the wiring harness male connector and the spring.

[0009] In the above-mentioned quick disassembly and assembly structure with a wiring harness headrest, the upper end of the wiring harness male connector has a groove and a plurality of circuit contact posts located in the groove, and the lower end of the wiring harness female connector has a protrusion that can be embedded in the groove, and the protrusion has a plurality of circuit contact rings arranged at intervals along its radial direction, and the circuit contact rings and the circuit contact posts are arranged in a one-to-one corresponding manner. The circuit contact ring at the lower end of the wiring harness female connector is a ring-shaped circuit coil structure. No matter what angle the circuit contact post at the upper end of the wiring harness male connector and the wiring harness female connector are in, as long as the circuit contact ring and the circuit contact post are connected up and down, the circuit contact post on the wiring harness male connector can always match the corresponding circuit contact ring on the wiring harness female connector. Therefore, this structure has low requirements for assembly accuracy. In addition, the matching structure of the protrusion at the lower end of the wiring harness female connector and the groove at the upper end of the wiring harness male connector makes the disassembly and assembly of the wiring harness female connector and the wiring harness male connector more convenient.

[0010] In the aforementioned quick-disassembly structure for a headrest with a wiring harness, the male wiring harness connector is provided with a first magnetic member, and the female wiring harness connector is provided with a second magnetic member that engages with the first magnetic member. When the male and female wiring harness connectors are connected, the first and second magnetic members form a magnetic attraction to facilitate the connection between the two, thereby facilitating quick connection and enhancing assembly and disassembly of the male and female wiring harness connectors.

[0011] Compared with the existing technology, the advantage of the quick disassembly and assembly structure of the present invention with a wiring harness headrest is that when the seat headrest is adjusted in height, under the action of the spring, the wiring harness male connector and the wiring harness female connector remain connected, so that the headrest height can still be adjusted while ensuring the function of the audio-visual system. At the same time, under the action of external force, the wiring harness headrest can be quickly disassembled and assembled. BRIEF DESCRIPTION OF THE DRAWINGS

The quick disassembly structure includes a wiring harness female connector 3 and a wiring harness male connector 4 that are detachably connected up and down. The wiring harness female connector 3 is arranged on the headrest rod 2, and the wiring harness male connector 4 is arranged on the guide sleeve 1 and can be moved along the length direction of the guide sleeve 1. The guide sleeve 1 is provided with a guide hole 1a along its length direction, and the wiring harness male connector 4 has a guide block 4a, and the guide block 4a is embedded in the guide hole 1a. A spring 5 is provided between the wiring harness male connector 4 and the inner wall of the guide sleeve 1, and under the action of the spring 5, the wiring harness male connector 4 and the wiring harness female connector 3 remain connected.

[0020] Specifically, refer to Figure 1-5 The headrest rod 2 is cylindrical and has an L-shaped notch 2a at its lower end. The wiring harness female connector 3 has a protrusion 3a, and the protrusion 3a is embedded in the notch 2a.

[0021] More specifically, refer to Figure 1-5 The guide sleeve 1 includes a cylindrical guide sleeve body 1b and an end cover 1c detachably arranged at the lower end of the guide sleeve body 1b, the end cover 1c has a makeshift hole 1c1 for the wiring harness to pass through, the lower end of the spring 5 abuts against the inner wall of the end cover 1c, and the upper end of the spring 5 is sleeved on the wiring harness male connector 4; the upper end of the wiring harness male connector 4 has a groove 4b and a plurality of circuit contact columns 4c located in the groove 4b, the lower end of the wiring harness female connector 3 has a protrusion 3b that can be embedded in the groove 4b, and the protrusion 3b has a plurality of circuit contact rings 3c arranged at intervals along its radial direction, and the circuit contact rings 3c and the circuit contact columns 4c are arranged in a one-to-one correspondence.

[0022] In this embodiment, the wiring harness male connector 4 is preferably provided with a first magnetic component, and the wiring harness female connector 3 is provided with a second magnetic component that is attracted and matched with the first magnetic component.

[0023] The following describes the working principle of the quick-disassembly and assembly structure of the headrest with wiring harness:

[0024] When the seat headrest is adjusted in height, the headrest rod 2 moves up and down under the action of external force, and the wiring harness female connector 3 can move up and down synchronously with the headrest rod 2, and the wiring harness male connector 4 can move up and down synchronously with the wiring harness female connector 3 under the action of the spring 5. At the same time, the matching structure of the guide block 4a and the guide hole 1a can guide the movement of the wiring harness male connector 4, so that the wiring harness female connector 3 set on the headrest rod 2 and the wiring harness male connector 4 set on the guide sleeve 1 can always remain connected, so that the headrest height can still be adjusted while ensuring the function of the audio-visual system. In addition, due to the limiting effect of the upper edge of the guide hole 1a on the guide block 4a on the wiring harness male connector 4, after the wiring harness male connector 4 moves upward to the highest position (that is, the position where the guide block 4a contacts the upper edge of the guide hole 1a), the wiring harness male connector 4 cannot Further move upward, and the wiring harness female connector 3 can continue to move upward with the headrest rod 2 and disconnect from the wiring harness male connector 4. When the wiring harness male connector 4 and the wiring harness female connector 3 need to be reconnected, the user only needs to reinsert the headrest rod 2 on the guide sleeve 1. The wiring harness female connector 3 can move downward synchronously with the headrest rod 2, and the spring 5 can support the wiring harness male connector 4, so the wiring harness female connector 3 follows the headrest rod 2 to move downward until it is connected to the wiring harness male connector 4, thereby realizing rapid disassembly and assembly of the wiring harness headrest. In addition, when the wiring harness male connector 4 and the wiring harness female connector 3 are connected, the first magnetic part and the second magnetic part (not shown in the figure) can form magnetic adsorption to assist the connection between the two, so that quick connection can be easily achieved, and at the same time, the disassembly and assembly of the wiring harness male connector 4 and the wiring harness female connector 3 are more operational.

[0025] The specific embodiments described herein are merely illustrative of the spirit of the present invention. Persons skilled in the art may make various modifications, additions, or substitutions to the described specific embodiments without departing from the spirit of the present invention or exceeding the scope defined by the appended claims.
