It should be noted that: like reference numbers and letters refer to like items in the following figures, and thus, once an item is defined in one figure, further discussion thereof is not required in subsequent figures.
As shown in fig. 1 to 4, the invention provides an automobile seat adjusting device, which comprises a seat 1 and an adjusting mechanism, wherein the seat 1 comprises a headrest 2 and a headrest framework 21, the headrest framework 21 is arranged in the headrest 2, and the adjusting mechanism is arranged on the headrest framework 21 and is used for adjusting the distance between the headrest 2 and the head of a human body.
The adjusting mechanism comprises a sealed air cavity 3 and an electric air pump 4, the sealed air cavity 3 is sleeved on the headrest framework 21, and an inflation hole 23 communicated with the sealed air cavity 3 is formed in the headrest framework 21; the electric air pump 4 is provided with an air pump air outlet pipe 41 and an air pump air inlet 42, and the air pump air outlet pipe 41 is connected with the headrest framework 21 and is communicated with the sealed air cavity 3 through the inflation hole 23. The electric air pump 4 is electrically connected with a vehicle body power supply 6, so that the electric air pump 4 can adjust the volume of the sealed air cavity 3 under the control of the vehicle body power supply 6.
The automobile seat adjusting device disclosed by the invention mainly aims at the headrest 2 part of the seat 1, and can ensure that passengers can obtain more satisfactory comfortable feeling by adjusting the distance between the headrest 2 and the head of a human body, and meanwhile, the headrest 2 can better protect the head of the human body when the automobile body is braked suddenly and the like. The main adjusting mode is that the distance between the head of the human body and the headrest 2 of the seat 1 is adjusted by inflating and deflating the electric air pump 4 and the sealed air cavity 3 and matching with the deformed soft surface 32 facing the head of the human body.
Further, the headrest framework 21 is a hollow U-shaped tube structure, the air pump outlet tube 41 is connected with one end of the headrest framework 21, and the inflation hole 23 is arranged on a tube close to the air pump outlet tube 41. The headrest framework 21 is a U-shaped structure which is common in the prior art, and the difference of the conventional headrest framework 21 is that the headrest framework 21 of the present invention is a hollow structure, and an air inflation hole 23 is combined, so that the sealed air chamber 3 and the electric air pump 4 form an air flow channel.
Further, as shown in fig. 3, the sealed air chamber 3 includes an air chamber shell composed of a plurality of hard surfaces 33 and a deformable soft surface 32, and the deformable soft surface 32 faces the head of the human body. In practice, the invention mainly aims at adjusting the distance between the headrest 2 and the head of the human body, and only one surface of the headrest facing the head of the human body is deformed during the process of inflating the sealed air cavity 3 by the electric air pump 4, so that the adjustable distance range can be maximized. After inflation, the air pressure is increased, and the deformed soft surface 32 protrudes outwards, so that the distance between the surface of the headrest 2 and the head is reduced; when deflated, the surface of the headrest 2 becomes more distant from the head.
Further, as shown in fig. 2, a support column 31 is further provided inside the sealed air chamber 3, and the support column 31 is fixed on a hard surface 33 facing the deformable soft surface 32. As mentioned above, the headrest framework 21 of the present invention is a hollow structure, and the supporting pillar 31 can play a good role in supporting and strengthening in order to improve the overall strength of the headrest 2 and the sealed air chamber 3. When the air is completely discharged, the internal and external air pressures are balanced, and in order to ensure the safety protection performance of the headrest 2 when the whole vehicle collides, the soft surface is supported by a supporting block which is fixed on the hard surface 33 of the air cavity shell inside the air cavity.
Still further, the number of the supporting columns 31 is at least two, and an elastic cushion is arranged at the end part of the supporting column 31 close to the deformable soft surface 32. The plurality of support columns 31 make the strength of the sealed air cavity 3 higher, and the elastic cushion prevents the head of a human body from being damaged.
Further, a check valve for preventing the gas in the sealed air chamber 3 from flowing back and overflowing is provided inside the electric air pump 4. When the air pump is in use, air in the sealed air cavity 3 is blocked by the one-way valve of the electric air pump 4 and cannot escape, so that the air pressure in the sealed air cavity 3 is ensured.
Further, the headrest 2 comprises a foam 22, and the foam 22 is coated on the headrest framework 21 and the sealed air cavity 3, so that the softness and comfort of the headrest 2 are improved.
Further, as shown in fig. 1 and 4, the adjusting mechanism further includes a distance adjusting button 5, the distance adjusting button 5 is disposed on the outer side of the headrest 2 and is connected in series with the vehicle body power source 6 and the electric air pump 4 through a wire 7, an inflating button 51 is disposed on the distance adjusting button 5, and the inflating button 51 can form a closed loop with the vehicle body power source 6 and the electric air pump 4. When the inflation button 51 is not pressed, the electric air pump 4 is electrified to work, and the headrest 2 is inflated, so that the distance between the headrest 2 and the head of the human body is increased.
Still further, the distance adjusting button 5 is further provided with a deflation button 52, the deflation button 52 is communicated with the sealed air cavity 3, and the air in the sealed air cavity 3 can be discharged along the deflation button 52 by pressing the deflation button 52. Pressing the deflation button 52 to rest opens the vent valve on the button and allows air inside the headrest 2 to escape, thereby reducing the distance between the headrest 2 and the head of the person.
Further, the wire 7 of the distance adjusting button 5 extends out along the other end of the headrest framework 21, and the position where the wire 7 extends out of the headrest framework 21 is sealed, so that the wire 7 is positioned inside the headrest framework 21 for the convenience of appearance, and meanwhile, the wire 7 can be prevented from being damaged.
Further, the invention also comprises a distance sensor 8, and the distance sensor 8 is arranged in the foaming surface 22 at the front part of the headrest 2. After a distance adjustment, the vehicle records the head-to-headrest 2 distance value provided by the distance sensor 8 at that time. The automatic inflation and deflation is realized to keep the comfortable distance all the time. When the distance sensor 8 feeds back that the automobile master control distance is greater than the set comfortable distance, the electric air pump 4 is electrified to ensure that air enters the sealed air cavity 3 from the air charging hole 23 through the air pump air outlet pipe 41; when the air is inflated to a comfortable distance, the electric air pump 4 stops working, the air in the sealed air cavity 3 is blocked by the one-way valve of the air pump and cannot escape outwards, and the air pressure in the sealed air cavity 3 is ensured; when the distance sensor 8 feeds back that the automobile master control distance is less than the set comfortable distance, the air release button 52 on the distance adjusting button 5 is automatically opened, and the gas in the sealed air cavity 3 escapes from the air release button 52; when the deflation reaches the comfortable distance, the deflation button 52 on the distance adjusting button 5 is closed, and the gas in the sealed gas cavity 3 keeps the current state.
Although some specific embodiments of the present invention have been described in detail by way of examples, it should be understood by those skilled in the art that the above examples are for illustrative purposes only and are not intended to limit the scope of the present invention. It will be appreciated by those skilled in the art that modifications may be made to the above embodiments without departing from the scope and spirit of the invention. The scope of the invention is defined by the appended claims.
