[0036] 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.

[0037] like Figures 1 to 8As shown, the utility model is a quick-connection structure assembly of a car seat headrest, wherein a guide sleeve 1 is installed on the car seat, and a headrest support rod 2 connected to the headrest is movably inserted in the guide sleeve 1, comprising: a seat connector 3 connected to the guide sleeve 1, a guide portion 30 and at least two symmetrically arranged mounting portions 31 are formed in the middle position of the seat connector 3, the guide portion 30 is located at the top of the mounting portion 31, and is used to guide the headrest support rod 2 to extend into the interior of the seat connector 3, and is movably sleeved on the mounting portion 31; each mounting portion 31 is integrally injection-molded with a first conductive member 32, and the bottom of the first conductive member 32 is electrically connected to a wiring harness extending into the interior of the car seat; the headrest The connector 4 is connected to the end of the headrest support rod 2 away from the headrest. At least two symmetrically placed second conductive members 40 are injection molded in the headrest connector 4. The wiring harness in the headrest is electrically connected to the top of the second conductive member 40. A pressing portion 400 is formed at the bottom end of each second conductive member 40. The pressing portion 400 is recessed along the direction of the axis of the headrest connector 4, so that the pressing portion 400 can movably contact the first conductive member 32; when the headrest drives the second conductive member 40 away from the car seat, the pressing portion 400 slides along the length direction of the first conductive member 32 and movably contacts it, so that the second conductive member 40 and the first conductive member 32 always maintain electrical connection.

[0038] This solution mainly solves the problem of inconvenience in quick disassembly and assembly of headrests with wiring harnesses (electronic devices, such as wiring harnesses connected to speakers and microphones) when adjusting them up and down. Specifically, Figures 1 to 3 As shown, the bottom of the guide sleeve 1 installed on the seat frame is connected to the seat connector 3, so that during the process of the headrest driving the headrest support rod 2 to adjust, the seat connector 3 remains relatively motionless (that is, the first conductive member 32 is in a stationary state); Figure 1 , Figure 2 and Figure 5 As shown, the headrest connector 4 is connected to the headrest support rod 2, and the wiring harness connected to the electronic device in the headrest passes through the headrest support rod 2 and is electrically connected to the second conductive member 40 in the headrest connector 4. In addition, the abutting portion 400 formed at the bottom of the second conductive member 40 enables the headrest connector to move synchronously with the headrest support rod 2 during the process of the headrest driving the headrest support rod 2 to adjust the height, thereby ensuring that the abutting portion 400 is moved along the Figure 2 When moving in the vertical direction, it can always be in active contact and tight contact with the first conductive member 32 to achieve electrical connection between the first conductive member 32 and the second conductive member 40, effectively ensuring that the electronic components in the headrest can be used normally when the headrest is adjusted, and also providing convenience for the quick disassembly and assembly of the headrest, ensuring that the customer's user experience is not affected.

[0039] Preferably, the first conductive member 32, the second conductive member 40 and the wiring harness in this solution are connected by soldering.

[0040] The seat connector 3 also includes: a fixed column 33, which has a accommodating cavity 330 formed therein, and the fixed column 33 and the guide sleeve 1 are connected by ultrasonic welding; a socket 34, which is arranged in the middle position of the accommodating cavity 330 and is integrally injection molded with the fixed column 33, the mounting portion 31 is distributed on the outer wall of the socket 34 in the vertical direction, and the guide portion 30 is located at the top of the socket 34.

[0041] like Figure 2 and Figure 3 As shown, the fixing column 33 with the accommodating cavity 330 can be connected to the guide sleeve 1 by ultrasonic welding. This connection method enables the outer wall of the fixing column 33 to be flush with the outer wall of the guide sleeve 1, thereby saving the space occupied by the overall outer diameter after the two are connected; and the connector 34 and the fixing column 33 are integrally injection molded, which provides convenience for production and manufacturing, and also avoids deviations caused by workers during assembly and affects the smoothness of subsequent headrest height adjustment; in addition, in this solution, the mounting portion 31 and the guide portion 30 are both arranged on the connector 34, and the headrest connector 4 is used in conjunction with the connector 34 to ensure the normal use of the electronic components when the headrest is adjusted in height.

[0042] A guide block 10 is formed at the bottom end of the guide sleeve 1 , and the fixing column 33 can be movably sleeved on the guide block 10 and pressed against the guide sleeve 1 , so that the fixing column 33 and the guide sleeve 1 are placed coaxially.

[0043] Further, if Figure 4 As shown, the diameter of the guide block 10 is smaller than the outer diameter of the guide sleeve 1, so during the installation of the fixed column 33, the fixed column 33 can be pre-movably sleeved on the guide block 10, and then pressed against the guide sleeve 1 along the direction of the guide block 10. In other words, the guide block 10 provides a certain guiding and positioning effect for the installation of the fixed column 33, ensuring that the fixed column 33 and the guide sleeve 1 are stably and accurately pressed together, thereby providing a guarantee for the quality of subsequent ultrasonic welding.

[0044] The mounting portion 31 is provided with symmetrically arranged limiting baffles 310 , and a mounting cavity 311 is formed between the limiting baffles 310 and the socket 34 to limit the first conductive member 32 in the mounting cavity 311 .

[0045] Further, if Figure 3As shown, the connector 34 is arranged in the vertical direction inside the fixing column 33, and the limit baffles 310 are symmetrically distributed on the connector 34. It is worth noting that each limit baffle 310 is arranged in an L-shape, so that an installation cavity 311 can be formed together with the connector 34 between the two symmetrical limit baffles 310. The installation cavity 311 is also arranged in the vertical direction, so that when the first conductive member 32 is placed in the installation cavity 311, it can have a limiting effect on the first conductive member 32, thereby improving the stability of the first conductive member 32 in the connector 34.

[0046] It should be noted that there are at least two installation cavities 311 in the present solution, which can be adaptively adjusted according to the number of wiring harnesses, thereby ensuring the normal use of the electronic device under the electrical connection between the first conductive component 32 and the second conductive component 40. In addition, the first conductive component 32 and the seat connector in the present solution are also integrally injection molded, saving the inconvenient process flow of subsequent workers for installation.

[0047] A positioning block 35 is formed on the outer wall of the socket 34 and is located in the installation cavity 311 . A positioning hole 320 is formed on the first conductive member 32 and the positioning block 35 is inserted in the positioning hole 320 to prevent the first conductive member 32 from shaking.

[0048] Preferably, if Figure 2 As shown, the socket 34 protrudes outward to form a positioning block 35, and the positioning block 35 is exactly located in the installation cavity 311. Regardless of the injection molding or installation process of the first conductive member 32 and the socket 34, the cooperation between the positioning block 35 and the positioning hole 320 can position the first conductive member 32, ensuring that the first conductive member 32 is stably located in the installation cavity 311 without displacement, and providing a guarantee for the stability of the subsequent contact between the pressing portion 400 and the first conductive member 32 to achieve electrical connection.

[0049] The guide portion 30 is formed with a guide slope 300 and a limiting plane 301. The guide slope 300 is used to guide the headrest connector 4 to be movably mounted on the socket 34 and movably close to the limiting baffle 310; the limiting plane 301 is used to limit the distance that the headrest support rod 2 extends into the accommodating cavity 330.

[0050] Further, if Figure 2 , Figure 3 and Figure 6As shown, during the process of active plugging of the headrest connector 4 and the seat connector 3, the guide slope 300 can play a certain guiding effect on the plugging of the headrest connector 4, ensuring that the headrest connector 4 can be sleeved on the socket 34 along the specified position. At the same time, the limiting plane 301 located at the top of the socket 34 can limit the headrest support rod 2, that is, the limiting plane 301 can limit the plugging depth of the headrest connector 4 and the socket 34, while ensuring that the second conductive member 40 of the headrest connector 4 is stably electrically connected to the first conductive member 32 on the socket 34, it also avoids the wiring harness connected to the second conductive member 40 in the headrest from being damaged due to excessive plugging depth.

[0051] The headrest connector 4 also includes: a connecting column 41, which is T-shaped and threadedly connected to the inner wall of the headrest support rod 2; a guide groove 42 and an anti-slip block 43, the guide groove 42 is symmetrically arranged on the connecting column 41 along the vertical direction, and the second conductive member 40 is located in the guide groove 42; the anti-slip block 43 is located at the open end of the side wall of the guide groove 42 to prevent the second conductive member 40 from deflecting or shaking.

[0052] like Figure 2 , Figures 5 to 7 As shown, the connecting column 41 is connected to the headrest support rod 2 in an inverted T-shape, so that the end with a smaller diameter can extend into the headrest support rod 2, and an external thread (not shown in the figure) is provided thereon, so that it can be threadedly connected with the headrest support rod 2 with an internal thread, thereby improving the convenience of installation and disassembly; and the part with a larger diameter can be pressed against the end of the headrest support rod 2 to achieve a limiting effect when the connecting column 41 is connected to the headrest support rod 2; similarly, the guide grooves 42 are symmetrically distributed on the connecting column 41, and are arranged corresponding to the number of the above-mentioned installation cavities 311, so that the second conductive member 40 can be placed in the guide groove 42 and integrally injection-molded with the connecting column 41, and the anti-dropping block 43 is located at the open end of the side wall of the guide groove 42, as shown in FIG. Figure 5 As shown, the second conductive member 40 is further restricted in the guide groove 42 by the anti-slip block 43, which effectively prevents the pressing portion 400 from being unable to stably press against the first conductive member 32 due to the shaking of the second conductive member 40, thereby ensuring that the electronic components are always in normal use when the headrest is adjusted up and down.

[0053] A through hole 410 and a plurality of guide blocks 411 are formed in the connecting column 41 . The through hole 410 is movably mounted on the socket 34 . The plurality of guide blocks 411 are evenly distributed in the through hole 410 to guide the connecting column 41 to be movably mounted on the socket 34 .

[0054] like Figure 2 and Figure 6As shown, the through hole 410 on the connecting column 41 can be movably mounted on the socket 34 when the headrest is adjusted up and down. The cooperation between the two provides a guiding effect for the movable plugging between the connecting column 41 and the socket 34. Similarly, the guide block 411 is also symmetrically arranged. When the connecting column 41 is plugged into the socket 34, the guide block 411 can give the connecting column 41 a certain guiding effect, ensuring that the connecting column 41 is smoothly and stably plugged into the socket 34, which not only ensures the convenience and quality of assembly, but also improves the smoothness of the headrest when it is adjusted up and down.

[0055] Preferably, continue to refer to Figure 2 The guide block 411 in this embodiment is arranged in a bell-mouth manner, that is, the large end opening of the symmetrically arranged guide block 411 faces the socket 34. In this way, when the connecting column 41 is plugged into the socket 34, the guide block 411 with the large end opening can play a better guiding effect, thereby greatly improving the efficiency of assembly.

[0056] A clearance groove 412 is also formed on the connecting column 41, and the tightening portion 400 is arranged in a V shape and extends into the clearance groove 412, and a support block 412a is formed on the bottom wall of the clearance groove 412. The support block 412a is used to support the second conductive member 40 so that the second conductive member 40 can always maintain contact with the first conductive member 32 when moving.

[0057] like Figure 2 and Figure 5 As shown, the clearance groove 412 in this solution is interconnected with the above-mentioned guide groove 42, so the second conductive member 40 located in the guide groove 42 extends into the clearance groove 412, which provides a placement space for the V-shaped pressing part 400 on the one hand, and on the other hand, the support block 412a formed at the connection between the clearance groove 412 and the guide groove 42 not only supports the second conductive member 40, but also gives the second conductive member 40 an extrusion force toward the first conductive member 32, thereby ensuring that the second conductive member 40 can always maintain stable pressing contact with the first conductive member 32 to achieve electrical connection when the headrest is adjusted and moved, providing a guarantee for the normal playback and use of electronic devices when the headrest is adjusted up and down. When the pressing part 400 movably contacts the top of the first conductive member 32, as the headrest continues to move along Figure 2 The upward movement in the vertical direction enables the headrest connector 4 to be smoothly separated from the seat connector 3, thereby realizing the function of quick disassembly and assembly of the headrest.

[0058] It should be noted that the first conductive member 32 and the second conductive member 40 in this solution are both made of long copper sheets, and the two long copper sheets are used to contact each other to ensure that the wiring harness in the seat can be electrically connected to the wiring harness in the headrest; in addition, Figures 6 to 8As shown, in this solution, a 4-pin interface or a 2-pin interface structure can be used for different wiring harness situations, and the structures of the above-mentioned guide grooves 42, installation cavities 311 and other components can be adaptively adjusted. Of course, this embodiment is not limited to the two situations provided in this solution, and other types of interfaces can also be used to implement the functions in this solution.

[0059] It should be noted that all directional indications in the embodiments of the present invention (such as up, down, left, right, front, back...) are only used to explain the relative position relationship, movement status, etc. between the components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly.

[0060] In addition, in the present invention, the descriptions of "first", "second", "one", etc. are only used for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" or "second" may explicitly or implicitly include at least one of the features. In the description of the present invention, the meaning of "plurality" is at least two, such as two, three, etc., unless otherwise clearly and specifically defined.

[0061] In the present invention, unless otherwise clearly specified and limited, the terms "connection", "fixation", etc. should be understood in a broad sense. For example, "fixation" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements, unless otherwise clearly defined. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0062] In addition, the technical solutions between the various embodiments of the present invention can be combined with each other, but it must be based on the fact that ordinary technicians in the field can implement it. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such combination of technical solutions does not exist and is not within the scope of protection required by the present invention.
