Description

Technical Field

[0001] The utility model belongs to the field of automobile seats, and in particular relates to an air supply structure for a massage air bag of an automobile seat. Background Art

[0002] When the driver uses the car for a long distance or drives for a long time, he will not only feel mental fatigue, but also suffer from muscle stiffness and fatigue due to maintaining the same posture for a long time, and even lose the ability to concentrate on driving, which seriously affects driving safety. In order to solve this problem, massage air bags are installed on the car seats to massage the driver's back or legs to relieve fatigue. However, existing car seats are limited to installing backrest massage air bags or leg massage air bags. In order to provide an air source for the backrest massage air bags and the leg massage air bags, an air pump needs to be installed on each of the backrest massage air bags and the leg massage air bags, resulting in a lot of noise when massaging the back and legs. In order to reduce the noise, only backrest massage air bags or leg massage air bags can be installed, so the linkage between the backrest massage function and the leg massage energy supply cannot be achieved.

[0003] The purpose of the utility model is to solve the above-mentioned problem and to provide an air supply structure for a car seat massage air bag, which can make the backrest massage air bag and the leg massage air bag use the same air pump for air supply, thereby reducing the noise generated by the two air pumps during operation and realizing the linkage between the backrest massage function and the leg massage function.

[0004] In order to achieve the above-mentioned purpose, the utility model provides an air supply structure for a car seat massage air bag, comprising an air pump, which is arranged on a metal bracket of the car seat, and the air pump is connected to one end of a tee through an air pump air pipe, and the other two ends of the tee are respectively connected to one end of a first air pipe and one end of a second air pipe, the other end of the first air pipe is connected to a first electromagnetic reversing valve body on a leg massage air bag, and air is supplied to the leg massage air bag through the first electromagnetic reversing valve body, the other end of the second air pipe is connected to a second electromagnetic reversing valve body on a backrest massage air bag, and air is supplied to the backrest massage air bag through the second electromagnetic reversing valve body, a first buckle is provided between the tee and the metal bracket to prevent the tee from rotating, and springs are provided in the air pump air pipe, the first air pipe and the second air pipe to prevent the air pipes from bending.

[0005] As a further optimization, a second buckle is provided between the second air pipe and the metal bracket to prevent the second air pipe from colliding with the air pump.

[0006] As a further optimization, a clamp is provided between the second air pipe and the car seat wiring harness.

[0007] As a further optimization, the air pump is fixed to a metal bracket of the car seat by means of pins.

DETAILED DESCRIPTION

[0016] The terms "first", "second", "third", "fourth", etc. in the specification and claims of the present utility model and the above-mentioned drawings are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence. It should be understood that the numbers used in this way can be interchanged where appropriate, so that the embodiments described herein can be implemented in an order other than that illustrated or described herein.

[0017] The specific implementation of the present invention is described in detail below with reference to the accompanying drawings.

[0018] like Figure 1-Figure 4 As shown, an air supply structure for a car seat massage air bag includes an air pump 1, the air pump 1 is used to compress external air to provide an air source for a first electromagnetic reversing valve body 8 and a second electromagnetic reversing valve body 10, the air pump 1 is fixed to a metal bracket 2 of the car seat by a pin 14, and the fixation by the pin 14 can prevent the vibration on the metal bracket 2 from being transmitted to the air pump 1, thereby reducing the noise generated when the air pump is working, the air pump 1 is connected to one end of a tee 4 through an air pump air pipe 3, and the other two ends of the tee 4 are respectively connected to the first air pump 1 through the air pump air pipe 3. The tube 5 and the second air tube 6 are connected to the first electromagnetic reversing valve body 8 on the leg massage air bag 7 and the second electromagnetic reversing valve body 10 on the back massage air bag 9. The three-way 4 can divide the compressed air in the air pump 1 into two parts. One air source flows into the first electromagnetic reversing valve body 8 through the first air tube 5, and flows to the leg massage air bag 7 opposite thereto through the multiple branch air tubes connected to the first electromagnetic reversing valve body 8. By driving the multiple air bags on the leg massage air bag 7 to inflate or deflate, the passenger's legs are squeezed to achieve the leg massage effect. The second air source flows into the second electromagnetic reversing valve body 10 through the second air tube 6, and flows to the back massage air bag 9 opposite thereto through the multiple branch air tubes connected to the second electromagnetic reversing valve body 10. By driving the multiple air bags on the back massage air bag 9 to inflate or deflate, the passenger's waist is squeezed to achieve the waist massage effect.

[0019] In order to prevent the air flow direction in the trachea from causing the tee 4 to rotate, the present embodiment has a first buckle 11 clamped on the tee 4, and the bottom of the first buckle 11 is fixed to the metal bracket 2 to fix the tee 4. At the same time, since the second air pipe 6 is relatively long, in order to prevent the air flow direction in the second air pipe 6 from causing the second air pipe 6 to collide with other structures of the car seat, the present embodiment has a second buckle 12 clamped on the second air pipe 6 near the air pump 1, and the second buckle 12 is fixed on the metal bracket 2. A plurality of clips 13 are fixed on the cushion bracket 16, and the second air pipe 6 is clamped together with the car seat wiring harness 15 by the plurality of clips 13 to fix the second air pipe 6.

[0020] In order to prevent the air pump air pipe 3, the first air pipe 5 and the second air pipe 6 from bending and thus blocking the air path, springs are further provided in the air pump air pipe 3, the first air pipe 5 and the second air pipe 6 in this embodiment.

[0021] The air pump 1, the first electromagnetic reversing valve body 8 and the second electromagnetic reversing valve body 10 in this embodiment are connected to the LIN bus system through signals. The LIN bus system controls the inflation and deflation of multiple air bags on the leg massage air bag 7 and the multiple air bags on the backrest massage air bag 9 by controlling the air pump 1, the first electromagnetic reversing valve body 8 and the second electromagnetic reversing valve body 10, thereby ultimately achieving the linkage between the backrest massage function and the leg massage function by using the same pump source.

[0022] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the embodiments of the utility model, rather than to limit them. Although the embodiments of the utility model are described in detail with reference to the above embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the above embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the embodiments of the utility model.
