Description

Technical Field

[0001] This utility model relates to the field of automotive headrest technology, and in particular to a ventilated headrest with a built-in speaker. Background Technology

[0002] Conventional ventilated headrests have a fan installed inside, which generates airflow to circulate the air and improve the user experience. However, conventional ventilated headrests do not have an additional speaker to improve sound quality, mainly because the fan inside the headrest would generate noise and affect the normal operation of the speaker. To combine the ventilated headrest and the speaker, the entire structure needs to be improved. Summary of the Invention

[0003] The technical problem to be solved by this utility model is to provide a ventilated headrest with a built-in speaker, which improves passenger comfort, avoids mutual interference between the speaker and the fan, and has the characteristics of simple structure and easy assembly.

[0004] The technical solution adopted by this utility model to solve its technical problem is as follows: a ventilated headrest with built-in speakers is provided, including a back shell, a frame, a front foam sponge, and a front cover. The frame has a fan mounting port in the middle that runs through the front and rear ends. Two speaker mounting slots are symmetrically arranged on both sides of the fan mounting port and at the rear end of the frame. A silent fan is installed in the rear of the fan mounting port. Built-in speakers are installed in the speaker mounting slots. The back shell is installed on the rear side of the frame. The front foam sponge is installed on the front side of the frame. The front foam sponge has several combined ventilation holes corresponding to the fan mounting port in the middle. The front cover is installed on the front side of the front foam sponge.

[0005] This technical solution utilizes a speaker mounting slot to facilitate the installation of the built-in speaker. A fan mounting port is provided for installing a silent fan, and since the fan mounting port penetrates the frame, the noise generated by the fan will be blocked by the frame, thus ensuring that the fan will not affect the normal operation of the speaker. Front foam is installed to improve the comfort of the headrest, and combined ventilation holes are set on the front foam to allow the airflow from the fan to blow forward, improving user comfort.

[0006] As a supplement to this technical solution, a number of forward-extending plug-in buckles are provided at the front edge of the rear shell, and the frame is provided with plug-in ports that match the plug-in buckles.

[0007] In this technical solution, snap-fit ​​buckles and snap-fit ​​ports are used to facilitate quick docking between the back shell and the frame.

[0008] As a supplement to this technical solution, a row of air inlets is provided at the upper middle part of the rear shell, and a reinforcing rib structure corresponding to the position of the air inlets is provided in the front inner cavity of the rear shell. The reinforcing rib structure is in the shape of a grid and extends to the air inlets at the upper end.

[0009] In this technical solution, an air inlet is set up to draw in external air, and a reinforcing rib structure is set up to improve the structural strength of the air inlet.

[0010] As a supplement to this technical solution, the upper and lower sides of the built-in speaker are provided with mating extensions, and the upper and lower sides of the speaker mounting slot are provided with mating post structures that match the mating extensions.

[0011] This technical solution improves the connection strength of the speaker by setting up a docking extension edge and docking column structure.

[0012] As a supplement to this technical solution, a number of first sound-permeable holes are provided at the bottom of the speaker mounting slot, which are used for convenience.

[0013] As a supplement to this technical solution, a ring of sound-insulating foam is installed inside the fan mounting port to surround the silent fan. By designing the sound-insulating foam, it is used to wrap the silent fan and prevent the noise of the fan during operation from affecting the speaker.

[0014] As a supplement to this technical solution, a central positioning seat is provided above the fan mounting port on the rear end face of the frame, and a snap-fit ​​arc opening is provided on the lower side of the central positioning seat. Headrest support rod mounting seats are symmetrically provided on the lower part of the frame, and a headrest support rod is installed in the snap-fit ​​arc opening of the central positioning seat. The vertical rod of the headrest support rod protrudes from the headrest support rod mounting seat.

[0015] In this technical solution, a central positioning seat and a headrest support rod mounting seat are provided to facilitate the installation of the headrest support rod.

[0016] As a supplement to this technical solution, a wire harness is installed on the skeleton, and a pressure sensor is installed on the front end face of the front foam sponge.

[0017] As a supplement to this technical solution, a positioning protrusion extending backward is provided at the lower rear side of the front foam sponge, and a mating groove matching the positioning protrusion is provided at the lower front end face of the skeleton.

[0018] As a supplement to this technical solution, the front end face of the front foam sponge has a concave arc structure in the middle, and the left and right sides of the front foam sponge are provided with second sound transmission holes corresponding to the built-in speaker. The rear end face of the front foam sponge and the lower side of the sound transmission hole are provided with positioning cuts.

[0019] Beneficial effects: This utility model relates to a ventilated headrest with a built-in speaker. The speaker mounting slot facilitates the installation of the built-in speaker, and a fan mounting port is provided for installing a silent fan. The fan mounting port penetrates the frame, blocking noise generated by the fan and ensuring it does not interfere with the normal operation of the speaker. Front foam sponge enhances the headrest's comfort, and combined ventilation holes on the front foam sponge allow the fan's airflow to blow forward, further improving user comfort. It features improved passenger comfort, prevents interference between the speaker and fan, and boasts a simple structure and easy assembly. Attached Figure Description
