Description

Technical Field

[0001] The utility model belongs to the technical field of seat headrest audio systems, and in particular relates to a headrest audio system installation component. Background Art

[0002] At present, the headrest audio system is installed by fixing the headrest plastic part on the audio mounting part by upper clip connection and lower thread connection. When the audio system fails, the seat back cover, seat rear window assembly and headrest rear foam need to be removed one by one before the headrest plastic part can be removed to replace or repair the audio system. Since the headrest plastic part is connected to the upper part of the audio mounting part by a non-detachable clip structure, it is difficult to remove once it is buckled, and tools are needed for removal. However, there is a risk of damage to the clip structure after removal, making reinstallation difficult. Utility Model Content

[0003] The utility model aims to provide a headrest audio installation component, which is easy to install and disassemble, and convenient for audio maintenance, and solves the problem that the headrest plastic part can only be removed after the seat back cover, the seat rear window component and the foam on the rear side of the headrest are removed one by one, and the headrest plastic part is connected to the upper part of the audio installation component by a clip-on structure, which makes it difficult to remove once it is buckled.

[0004] To this end, the technical solution adopted by the utility model is: a headrest audio installation assembly, including an audio installation piece fixedly installed on the front side of the headrest rod and a headrest plastic piece installed on the front side of the audio installation piece, the headrest plastic piece and the audio installation piece form a cavity for accommodating the audio, and hooks are symmetrically arranged at intervals on the top of the rear side of the headrest plastic piece, the audio installation piece includes an audio installation upper plate welded to the upper cross bar of the headrest rod and an audio installation lower plate correspondingly welded to the vertical bars of the headrest rod on the left and right sides, the top of the audio installation upper plate is provided with a limiting ring corresponding to the hook facing forward, and the bottom of the audio installation lower plate is threadedly connected to the bottom of the headrest plastic piece, and when the bottom of the headrest plastic piece is not connected to the headrest plastic piece, the headrest plastic piece can be flipped open and removed to directly expose the audio installed on the audio installation piece.

[0005] As a preferred embodiment of the above scheme, a horizontal limit plate is provided in the center of the top of the audio installation upper plate, extending horizontally forward to be welded to the bottom end of the middle part of the limit ring, and the width of the horizontal limit plate matches the distance between the hooks, thereby limiting the left and right horizontal position of the headrest plastic part, preventing the headrest plastic part from moving left and right when it is turned over when the bottom of the headrest plastic part is not connected to the headrest plastic part, and the design structure is reasonable.

[0006] It is further preferred that three welding platforms are symmetrically arranged on the left, middle and right sides of the bottom rear side of the audio installation upper plate, which are fitted with the upper cross bar of the headrest rod, and the welding platform arranged in the center and in contact with the horizontal section of the upper cross bar of the headrest rod is the main welding point, and the welding platforms arranged on the left and right and in contact with the bending section of the upper cross bar of the headrest rod are secondary welding points. The triangle is welded stably, the horizontal section welding is convenient and firm, the welding process requirements are low, the primary and secondary welding positions are reasonably designed, and the headrest rod is provided with corresponding positioning triangular protrusions that press against the upper and lower edges of the welding platform, so that the bottom edge of the welding platform is directly pressed against the positioning triangular protrusions for welding during welding and installation, and the positioning structure is reasonably designed.

[0007] Further preferably, the left and right sides of the audio installation lower plate are provided with welding side plates welded to the non-bending sections of the left and right uprights of the headrest rod, and the welding is firm. Compared with the arc structure of the welding edge of the existing headrest plastic parts covering the uprights, the welding process difficulty of the non-bending sections of the uprights adopted in this solution is significantly lower, and the welding side plates do not need to cover the uprights, and the manufacturing process cost is low; the headrest rod is correspondingly provided with a welding positioning platform that rests against the outer edge of the welding side plate, and the lower part of the audio installation lower plate is correspondingly provided with a window shell mounting hole, with high space utilization and reasonable design.

[0008] Further preferably, a headrest foam and a headrest cover for fixing the headrest foam are installed on the front side of the headrest plastic part, and mounting bosses threadedly connected to the bottom of the audio mounting lower plate are symmetrically spaced on the left and right sides of the bottom rear side of the headrest plastic part. An opening is provided on the outer side of the mounting bosses and is equipped with a reed lock nut to facilitate locking of the rear mounting screws, which has a reasonable design.

[0009] Further preferably, the headrest plastic part protrudes outward symmetrically and is provided with sound holes for sound emission, and a plane structure is provided in the middle, thereby increasing the foam thickness in the head contact area and improving comfort. The design is reasonable, and the mounting boss adopts a hollow structure to allow the headrest foam to be inserted and positioned, which is ingeniously designed.

[0010] Beneficial effects of the utility model:

[0011] (1) Compared with removing the seat back cover, the seat rear window assembly and the foam on the back of the headrest to remove the headrest plastic part, this solution adopts a hook structure for the headrest plastic part and the upper part of the audio installation part, so there is no need to remove the seat cover and the foam on the back of the headrest. Only the seat rear window assembly needs to be removed to expose the connecting screws between the headrest plastic part and the lower part of the audio installation part. By directly removing the screws, the headrest plastic part can be turned over to completely expose the audio installed on the audio installation part, and the audio can be directly repaired or replaced, effectively avoiding the difficulty of reinstallation after disassembly. In addition, the seat rear window assembly itself is a detachable buckle installation, which can be directly pried open manually, making disassembly convenient and quick.

[0012] (2) Compared with the headrest plastic part and the upper part of the audio installation part connected by a snap-on structure, the audio installation part of this solution is divided into two parts to form an audio installation upper plate and an audio installation lower plate, which effectively reduces the cost. The top of the audio installation upper plate is provided with a limit ring corresponding to the hook on the front, and the bottom of the audio installation lower plate is threadedly connected to the bottom of the headrest plastic part. The upper and lower positioning is stable, the hook method is convenient and quick to install and disassemble, the conception is ingenious, and the design structure is linked together.

[0013] In summary, it has the advantages of convenient and quick audio repair or replacement, stable upper and lower positioning, convenient and quick installation and disassembly by hooking, ingenious conception, and interlocking design structure. BRIEF DESCRIPTION OF THE DRAWINGS
