[0024] See also Figures 1 to 4The utility model provides a detachable audio headrest structure, including a headrest guide rod 1 and a bracket 3, wherein an audio body 10 is mounted on the headrest guide rod 1, and the headrest guide rod 1 is detachably mounted on the backrest 2; the bracket 3 is mounted on the backrest 2, and a connecting portion 30 docking with the headrest guide rod 1 is provided on the bracket 3; wherein the end of the headrest guide rod 1 extends into the connecting portion 30 along the mounted backrest 2, and an audio connector 11 connected to the audio body 10 is also provided at the end of the headrest guide rod 1, and an audio interface 32 docking with the audio connector 11 is provided on the connecting portion 30.
[0025] Specifically, when the seats in the passenger compartment of a car need to be laid flat to form a bed, in order to obtain a more flat surface, it is often necessary to remove the headrests on the seats so that the car seats can be fully laid flat. For a car cabin with limited internal space, when the front seats of the car are laid forward, removing the headrests can avoid interference with the instrument panel and being unable to lay flat. Similarly, when the front seats of the car are laid backward, removing the headrests can avoid interference with the rear seats and being unable to lay flat. For the rear seats of the car, it is also possible to avoid interference between the headrest and the front seat back 2 when they are laid forward.
[0026] Furthermore, for headrests with audio functions, especially audio bodies 10 with wired connections, compared to Bluetooth speakers, independent power supply is not required, and the Bluetooth signal will not be affected, so the audio effect is better and more stable. In the process of loading and unloading the headrest to the seat back 2, the audio connection between the audio body 10 and the car cabin also needs to be considered. Therefore, the headrest guide rod 1 of the audio headrest is docked by the bracket 3 set on the backrest 2. On the one hand, the backrest 2 is assisted to fix the headrest guide rod 1; on the other hand, the audio connector 11 at the end of the headrest guide rod 1 and the audio interface 32 in the connecting part 30 on the bracket 3 are connected to realize the synchronous connection or disconnection of the audio connection of the audio body 10 during the loading and unloading of the headrest. Among them, the structure of the audio connector 11 and the audio interface 32 can be designed with reference to the plug-in structure between general audio and microphone, such as 3.5mmTRS terminal interface.
[0027] In this way, the headrest guide rod 1 with the audio body 10 is connected by the bracket 3 set on the seat back 2 to solve the problem that the existing headrest with audio cannot be disassembled or is difficult to disassemble. The technical solution of the detachable headrest with audio is realized by connecting the commonly used audio connector 11 and the audio interface 32. At the same time, compared with the Bluetooth audio headrest, it does not require Bluetooth connection and irregular charging, which is more convenient. And the bracket 3 structure can be directly adapted to the back 2 and audio headrest of the existing car seat.
[0028] See also Figure 2In one embodiment, the headrest guide rod 1 is configured to be U-shaped and is invertedly mounted on the backrest 2 , and the audio body 10 is respectively mounted on both sides of the headrest guide rod 1 .
[0029] Furthermore, the bracket 3 is configured as an L-shaped sheet metal part, and the bracket 3 is connected to an end portion of one side of the headrest guide rod 1 .
[0030] Furthermore, a mounting hole 31 for mounting the connecting portion 30 is formed on the bracket 3 , and the axial direction of the mounting hole 31 coincides with the axial direction of the end of the headrest guide rod 1 mounted on the backrest 2 .
[0031] Specifically, for the structure of the headrest guide rod 1 of the car seat, the commonly used one is an inverted U-shaped one, which can be directly plugged and unplugged on the seat back 2. At the same time, the audio body 10 in the audio headrest is installed on both sides of the headrest guide rod 1, which is adapted to the ear position of the person sitting on the seat.
[0032] Furthermore, the structure of the bracket 3 used to realize the audio connection with the headrest of the sound system is installed according to the position where the headrest guide rod 1 is installed on the backrest 2, and the bracket 3 can be installed in a lightweight sheet metal structure by taking advantage of the sufficiently high strength of the frame of the seat backrest 2, so as to provide an installation position for the connection part 30 provided on the bracket 3. In this way, the bracket 3 is arranged in an L shape and installed on the seat backrest 2 for fixing.
[0033] More specifically, for the bracket 3 of the sheet metal structure, a mounting hole 31 is opened thereon to stably mount the connecting portion 30, and at the same time, in order to maintain the docking accuracy between the connecting portion 30 and the end of the headrest guide rod 1, the axial position of the mounting hole 31 is overlapped with the axial position of the end of the headrest guide rod 1 connecting the bracket 3. In this way, the connecting portion 30 mounted on the mounting hole 31 of the bracket 3 meets the docking accuracy with the end of the headrest guide rod 1.
[0034] See also Figure 4 In one embodiment, the connecting portion 30 includes a guide cover 301 and a docking terminal 302. The guide cover 301 is a cylindrical structure and is sleeved in the mounting hole 31, and a flange is provided at the top of the guide cover 301; the docking terminal 302 is a cylindrical structure and is installed in the guide cover 301. The audio interface 32 is installed in the docking terminal 302, and a flange is also provided at the bottom of the docking terminal 302; the guide cover 301 and the docking terminal 302 are respectively located on the upper and lower sides of the mounting hole 31 through their respective flanges.
[0035] Furthermore, the outer diameter of the guide cover 301 is smaller than the inner diameter of the mounting hole 31 , and the inner diameter of the guide cover 301 is larger than the outer diameter of the headrest guide rod 1 ; the outer diameter of the docking terminal 302 is not larger than the inner diameter of the guide cover 301 , and the inner diameter of the docking terminal 302 is larger than the outer diameter of the end of the headrest guide rod 1 .
[0036] Furthermore, a spring 303 is installed on the outer side of the guide cover 301 , and two ends of the spring 303 are respectively located on the flange of the guide cover 301 and the bracket 3 , and the spring 303 sleeves the guide cover 301 therein.
[0037] Specifically, the connection part 30 can be composed of a guide cover 301 and a docking terminal 302, each with a flange structure, and the two are mounted on the mounting hole 31 of the bracket 3 in a mutually connected state, and the flanges of the two are used to ensure that they are engaged with the mounting hole 31 of the bracket 3. In this way, the length of the bracket 3 docking with the headrest guide rod 1 is increased to ensure the stability of the structural connection and audio connection therebetween.
[0038] Furthermore, the relationship between the inner and outer diameters of the guide cover 301 and the docking terminal 302 of the cylindrical structure in the connecting part 30 and the outer diameter of the headrest guide rod 1 is such that the guide cover 301 and the docking terminal 302 can be connected and fixed to form the function of the connecting part 30 for the headrest guide rod 1; and the guide cover 301 and the docking terminal 302 can also be slid relative to the mounting hole 31 of the bracket 3 to adapt to the position of the audio connector 11 at the end of the headrest guide rod 1 installed on the backrest 2, thereby ensuring a stable connection with the audio interface 32 in the docking terminal 302.
[0039] More specifically, by installing a spring 303 on the periphery of the guide cover 301, and respectively abutting the two ends of the spring 303 against the flange of the guide cover 301 and the bracket 3 outside the mounting hole 31, the entire structure of the connecting portion 30 can be propped up. Therefore, when the guide cover 301 and the docking terminal 302 are assembled through the mounting hole 31 of the bracket 3 of the sheet metal structure, the spring 303 installed on the periphery of the guide cover 301 plays a buffering role when the headrest guide rod 1 is inserted, thereby preventing the parts from being damaged due to strong assembly.
[0040] See also Figure 3 In one embodiment, the audio harness 101 of the audio main body 10 is connected to the audio connector 11 at one end along the headrest guide rod 1, and the audio harness 101 connected to the audio interface 32 is also arranged on the outer side of the docking terminal 302, and the audio harness 101 extends along the bracket 3 to the backrest 2. In this way, the multiple audio main bodies 10 installed at the seat headrest share the audio harness 101 arranged along the headrest guide rod 1, and are connected to the audio interface 32 in the connecting part 30 on the bracket 3 along one end of the headrest guide rod 1.
[0041] The utility model also provides a seat, comprising the above-mentioned detachable audio headrest structure, so that during the assembly and disassembly process of the seat headrest, the headrest audio can still maintain the stability of the audio connection after multiple assembly and disassembly.
[0042] In summary, the utility model provides a detachable audio headrest structure and seat, which realizes the technical solution of detachable audio headrest through the commonly used audio connector and audio interface connection method; at the same time, the connection part installed on the bracket mounting hole meets the accuracy of docking with the end of the headrest guide rod; and the spring installed on the periphery of the guide cover plays a buffering role to prevent damage to parts caused by strong assembly.
[0043] The above embodiments are merely illustrative of the principles and effects of the present invention, and are not intended to limit the present invention. Anyone familiar with the technology may modify or alter the above embodiments without departing from the spirit and scope of the present invention. Therefore, all equivalent modifications or alterations made by a person of ordinary skill in the art without departing from the spirit and technical concept disclosed in the present invention shall still be covered by the claims of the present invention.
