Description

Technical Field

[0001] The present application relates to the technical field of automobile seats, and in particular to a multimedia automobile seat headrest and seat. Background Art

[0002] The headrest on the car seat is an auxiliary device set up to improve the comfort and safety of the car. The main function of the headrest is to provide support for the passenger's head, reduce fatigue, and play a buffering role in the event of a vehicle collision to protect the passenger's head and neck.

[0003] When the driver is driving, the body leans on the seat and the head leans on the headrest. If the driver feels tired after driving for a long time, the driver often drinks some refreshing drinks or applies auxiliary ointments such as Fengyoujing to refresh himself, but such operations have safety hazards. If the driver is driving alone, he needs to park the car on the roadside to operate. If the car is on the highway and cannot stop, if the driver operates by himself, the driver's gestures must be separated from the steering wheel, and the line of sight will also be separated from the front of the car, which increases the safety hazard of car driving at high speeds.

[0004] Application Contents In order to reduce the potential safety hazard of automobile driving, the present application provides a multimedia automobile seat headrest and seat.

[0006] By adopting the above technical solution, when refreshing, the driver puts the back of the neck against the neck pillow, starts the micro pump, and allows the water in the water tank to pass through the rubber tube group and then return to the water tank. During this process, the driver's back neck contacts the relatively cool rubber tube group, achieving the effect of refreshing the driver. The temperature of the back of the neck of the human body is normal human body temperature, and there are many blood vessels in this area. After touching a relatively cold object, the human body will be stimulated. The back of the driver's neck briefly contacts the water-filled rubber tube, causing the blood vessels in the back of the neck to contract, achieving the effect of instantly refreshing the driver. Compared with the existing technology, it prevents the driver's hands from leaving the steering wheel, and the line of sight will not be diverted to the front of the car, reducing the safety hazards of car driving.

[0014] By adopting the above technical solution, when driving the limiting pin, the rotating plate is rotated to rotate the limiting arc bar, and the connecting block is moved through the cooperation between the connecting block and the limiting arc bar and the cooperation between the connecting block and the limiting groove, thereby achieving the effect of driving the limiting pin to move.

[0015] Optionally, two limiting circular plates are connected to the mounting rod, and during installation, the mounting frame is located between the two limiting circular plates.

[0016] By adopting the above technical solution, when installing the pillow body, the two limiting pins are aligned with the two limiting holes, and the balance is difficult to control, which increases the difficulty of installing the pillow body. The two limiting circular plates are used to limit the installation height of the mounting frame, which facilitates the alignment of the limiting pins with the limiting holes, thereby improving the convenience of installing the neck pillow.

[0017] A multimedia car seat comprises a seat, wherein a plurality of massage flanges are arranged on the seat surface, a pillow body is arranged on the top of the seat, and a limiting component for limiting the pillow body is arranged on the seat.

[0020] By adopting the above technical solution, when installing the pillow body, the pressure cylinder is raised, the pressure spring is compressed, and then the mounting rod is inserted into the mounting hole, so that the limiting flange moves in the spiral arc groove. When the limiting flange descends, it drives the rotating cylinder to rotate until the bottom end of the mounting rod touches the bottom end of the mounting hole. The pressure cylinder is released and the pressure cylinder is lowered by the force of the pressure spring until the locking serrations engage with the connecting serrations, thereby limiting the mounting rod and the freedom of the pillow body, thereby achieving the installation of the pillow body.

[0021] Optionally, a placement groove is provided on the back of the seat, a display screen is installed in the placement groove, and a protective member for protecting the display screen is provided on the seat.

DETAILED DESCRIPTION

[0035] The following is combined with Figure 1-Figure 8 This application is described in further detail.

[0036] The embodiment of the present application discloses a multimedia car seat headrest and seat. Figure 1 The multimedia car seat headrest comprises a pillow body 1, and a plurality of mounting rods 11 are fixedly connected to the bottom of the pillow body 1, and two mounting rods are taken as an example in this embodiment.

[0037] Reference Figure 2 and Figure 3A neck pillow 2 is arranged on the pillow body 1, and the inside of the neck pillow 2 is filled with memory foam, and the memory foam is used to improve the comfort of the driver. A mounting assembly 3 is arranged on the neck pillow 2, and the mounting assembly 3 includes a mounting frame 31, a limiting pin 32 and a mounting spring 33. The mounting frame 31 is fixedly connected to the neck pillow 2, and a limiting pin 32 is slidably matched at both ends of the mounting frame 31, and the two limiting pins 32 are arranged opposite to each other. A connecting ring is fixedly connected to the limiting pin 32, and the mounting spring 33 is sleeved on the limiting pin 32 and is located between the connecting ring and the mounting frame 31. Two limiting circular plates 111 are fixedly connected to the mounting rod 11, and a limiting hole matching the shape of the limiting pin 32 is arranged between the two limiting circular plates 111. The limiting circular plate 111 is used to limit the installation position of the mounting frame 31, so as to facilitate the quick installation of the pillow body 1.

[0038] Reference Figure 2 and Figure 3 , a driving assembly 4 is arranged on the mounting frame 31, and the driving assembly 4 includes a rotating plate 41, a fixed plate 42, a connecting block 43 and a limiting arc bar 44. The connecting block 43 is fixedly connected to the limiting pin 32, and the connecting block 43 is a T-shaped block. The fixed plate 42 is fixedly connected to the mounting frame 31, and a limiting groove 421 is opened at the position of the fixed plate 42 corresponding to the connecting block 43, and the connecting block 43 is slidably fitted in the limiting groove 421. The rotating plate 41 is rotatably connected to the fixed plate 42, and two limiting arc bars 44 are fixedly connected to the rotating plate 41, and the limiting arc bars 44 correspond to the connecting block 43 one by one. The two limiting arc bars 44 are rotationally symmetrically arranged around the rotation axis of the rotating plate 41, and the limiting arc bars 44 are slidably fitted with the connecting block 43.

[0039] When installing the neck pillow 2, rotate the rotating plate 41, and through the restriction of the limiting arc bar 44 and the limiting groove 421, the two connecting blocks 43 are simultaneously moved toward the rotation axis of the rotating plate 41 to drive the limiting pin 32 to move, and then the mounting frame 31 is placed between the two limiting circular plates 111, and the rotating plate 41 is loosened. The limiting pin 32 moves in the opposite direction under the action of the mounting spring 33 and is inserted into the limiting hole, thereby limiting the freedom of the neck pillow 2 and realizing the installation of the neck pillow 2.

[0040] Reference Figure 1 and Figure 4 A refreshing component 5 is arranged between the neck pillow 2 and the pillow body 1, and the refreshing component 5 includes a rubber tube group 51, a water tank 52 and a micro pump 53. An installation cavity is opened in the pillow body 1, and the water tank 52 and the micro pump 53 are both installed in the installation cavity. An arc groove 21 is opened on the surface of the neck pillow 2, and the rubber tube group 51 is installed on the arc groove 21 and partially exposed from the arc groove 21. One end of the rubber tube group 51 is connected to the inside of the water tank 52, and the other end of the rubber tube group 51 is connected to the water outlet of the micro pump 53, and the water inlet of the micro pump 53 is connected to the inside of the water tank 52.

[0041] When refreshing is needed, the driver places the back of the neck against the arc groove 21 and contacts the rubber tube set 51, starts the micro pump 53, and makes the water in the water tank 52 pass through the rubber tube set 51. The relatively cool rubber tube set 51 stimulates the back of the driver's neck, which has the effect of refreshing the driver. In addition, the relatively cool water in this embodiment can certainly refresh the driver, but the water temperature should not be too low. The water in the water tank 52 of this application is set at a normal temperature of more than 20 degrees, and when the driver is against the rubber tube set 51, the micro pump 53 should not be started for a long time, and the back of the neck should not be cooled and stimulated for a long time.

[0042] Reference Figure 4 In order to improve the driver's comfort, an electric heating rod 521 is installed in the water tank 52, and the surface of the water tank 52 is wrapped with a heat insulation film, which is an aerogel heat insulation film in this embodiment. When the temperature inside the car is low, the water in the water tank 52 is heated by the electric heating rod 521, so that the driver's neck is close to the heated rubber tube group 51, which improves the driver's comfort.

[0043] The implementation principle of a multimedia car seat headrest in an embodiment of the present application is: when installing the neck pillow 2, rotate the rotating plate 41 to make the two connecting blocks 43 move toward the rotation axis position of the rotating plate 41 at the same time, drive the limiting pin 32 to move, and then place the mounting frame 31 between the two limiting circular plates 111, loosen the rotating plate 41, and the limiting pin 32 moves under the action of the mounting spring 33 and is inserted into the limiting hole to achieve the installation of the neck pillow 2.

[0044] When refreshing, the driver's neck is pressed against the rubber tube set 51, and the micro pump 53 is started to circulate between the water tank 52 and the rubber tube set 51. The cooler water stimulates the driver's neck through the rubber tube set 51, thereby achieving the effect of refreshing the driver.

[0045] The back of the human neck is always at normal temperature and has many blood vessels. After touching a cold object, the human body is easily stimulated. The back of the driver's neck briefly contacts the water-filled rubber tube group 51, which causes the blood vessels in the back of the neck to contract, thereby achieving an instant effect of refreshing the driver. Compared with the prior art, this prevents the driver's hands from leaving the steering wheel and the line of sight will not be diverted, thereby reducing the safety hazard of car driving.

[0046] Reference Figure 5 , Figure 6 and Figure 7A multimedia car seat includes a seat 6, which is arranged below a pillow body 1. A limiting assembly 7 is arranged on the seat 6, and the limiting assembly 7 includes a rotating cylinder 71, a limiting frame 72, a limiting flange 73, a pressure cylinder 74 and a pressure spring 75. The limiting frame 72 is installed on the top of the seat 6, and a mounting hole is opened on the limiting frame 72, and a mounting rod 11 is inserted into the mounting hole. A spiral arc groove 721 is arranged on the inner wall of the mounting hole, and the rotating cylinder 71 is rotatably connected to the mounting rod 11, and the limiting flange 73 is fixedly connected to the surface of the rotating cylinder 71 near the bottom end of the mounting rod 11, and the limiting flange 73 is slidably fitted in the spiral arc groove 721.

[0047] Reference Figure 6 and Figure 7 , a plurality of connecting strips 741 are fixedly connected to the inner wall of the pressure cylinder 74. In this embodiment, two connecting strips are used as an example. The connecting strips 741 are parallel to the mounting rod 11. The pressure cylinder 74 is slidably fitted on the mounting rod 11 through the connecting strips 741 and is located above the rotating cylinder 71. An operating plate is fixedly connected between the two pressure cylinders 74. A plurality of locking serrations 742 are fixedly connected to the bottom end of the pressure cylinder 74, and a plurality of connecting serrations 711 are fixedly connected to the top end of the rotating cylinder 71. The pressure spring 75 is sleeved on the mounting rod 11 and is located between the pressure cylinder 74 and the mounting rod 11. The locking serrations 742 are meshed with the connecting serrations 711.

[0048] When limiting the pillow body 1, the operating plate is lifted to make the pressure cylinder 74 rise, the pressure spring 75 is compressed, the locking serration 742 disengages from the connecting serration 711, and the mounting rod 11 is inserted into the mounting hole. During this process, the limiting flange 73 moves in the spiral arc groove 721, driving the rotating cylinder 71 to rotate until the bottom end of the mounting rod 11 touches the bottom end of the mounting hole. The operating plate is released, and the pressure cylinder 74 is lowered by the force of the pressure spring 75, and the locking serration 742 engages with the connecting serration 711, thereby limiting the freedom of the mounting rod 11 and realizing the installation of the pillow body 1.

[0049] Reference Figure 5 and Figure 8 , the surface of the seat 6 is provided with a plurality of massage flanges 61, which are used to massage the driver's back and improve the driver's comfort. The back of the seat 6 is provided with a placement groove, in which a display screen 62 is installed. A protective member 63 is provided at the notch of the placement groove, and the protective member 63 is a protective plate, and the protective member 63 is hinged at the notch of the placement groove. A strong magnetic block 64 is installed on the seat 6, and a magnetic metal block 65 is installed on the protective member 63. In this embodiment, an iron block is used as an example.

[0050] When protecting, the protective piece 63 covers the slot opening, and the strong magnetic block 64 attracts the magnetic metal block 65. When the protective plate is opened, it is placed on the passenger's legs and can also be used as a dining table.

[0051] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
