[0030] In order to make the technical problems, technical schemes and beneficial effects solved by the utility model clearer and more apparent, the utility model will be further described in detail below in combination with the drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the utility model and not used to limit the utility model.

[0031] As shown in Figure 1 and Figure 2 , an embodiment of the utility model provides a vehicle seat, including backrest, inflation device and air bag group, backrest includes backrest framework and backrest foam 1, backrest foam 1 is installed to backrest framework.

[0032] Air bag group includes mounting plate 3 and at least three air bags 4, mounting plate 3 is installed to backrest framework, at least three air bags 4 are arranged along the left and right direction of vehicle seat and are arranged corresponding to the shoulder area of backrest, air bag 4 is installed on mounting plate 3 and is located between mounting plate 3 and backrest foam 1, inflation device can be individually inflated to all air bags 4, and air bag 4 can support the shoulder of the occupant when being inflated. As shown in Figure 1 , the left and right direction is the left and right direction of the seat, and the front and back direction is the front and back direction of the seat.

[0033] Specifically, at least three air bags 4 arranged along the left and right direction of the vehicle seat are arranged corresponding to the shoulder area of the backrest, and after the inflation device inflates all air bags 4, the air bags 4 inflate to lift the backrest foam 1 to deform, so that the shoulder area of the backrest forms a certain support height to support the shoulders of the driver and passenger.

[0034] It should be understood that the front of the backrest foam 1 is provided with a face cover, and after the driver and passenger sit on the vehicle seat, the back of the driver and passenger directly contacts the face cover, the backrest framework and the backrest foam 1 provide support force for the driver and passenger, the backrest has a shoulder area corresponding to the shoulders of the driver and passenger, and the shoulder area of the backrest should support the shoulders of the driver and passenger. The position range of the shoulder area is obtained from the big data of the shoulder height and width of people of different heights, weights and postures, so that the shoulder area with a certain support height can support the shoulders of most people.

[0035] At least three air bags 4 are arranged corresponding to the shoulder area of the backrest, and it can be seen that the shoulder area of the backrest is divided into multiple sub-areas, and each air bag 4 can support a sub-area of the shoulder area of the backrest to disperse the center position lifted by the air bag 4. Moreover, since the inflation device can individually inflate each air bag 4, the inflation height of each air bag 4 can be individually adjusted, so that the support height of each sub-area of the shoulder area can be individually adjusted, so that the shoulder area of the backrest can adjust the support height according to the posture of the shoulders of the occupant, to fit the shoulders of the driver and passenger in the turning and sudden braking posture of the vehicle, and reduce the risk of injury of the personnel.

[0036] Specifically, before driving, the driver and passengers control the inflation device to inflate each air bag 4 via buttons or control panel. After the air bag 4 has been inflated for a set time or to a set height, the inflation device stops inflating the air bag 4.

[0037] It should be noted that drivers and passengers can adjust the airbag 4 to different inflation levels according to their own needs to find the most comfortable shoulder support height for themselves in different riding situations.

[0038] During normal driving, since the distance between the shoulder area of ​​the person and the shoulder area of ​​the backrest is usually the same at various positions along the left and right directions of the vehicle, the inflation height of the multiple air bags 4 distributed along the left and right directions is the same.

[0039] When the vehicle turns left, such as Figure 4 As shown, when the left side of the person's shoulder presses against the shoulder area of ​​the backrest, the right side of the person's shoulder will slightly move away from the shoulder area of ​​the backrest. At this time, the automatic inflation device inflates the right-side airbag 4, increasing its inflation height and thus increasing the support height of the right side of the backrest to accommodate the posture of the right side of the backrest, compensating for the distance the right side of the person's shoulder moves away from the backrest. Simultaneously, the automatic deflation device also deflates the left-side airbag 4, decreasing its inflation height and thus reducing the support height of the left side of the backrest to accommodate the posture of the left side of the backrest. This ensures that the shoulder area of ​​the backrest fully conforms to the person's shoulder during left turns, reducing the risk of injury.

[0040] Similarly, when a vehicle turns right, such as Figure 5 As shown, when the right side of the person's shoulder presses against the shoulder area of ​​the backrest, the left side of the person's shoulder will slightly move away from the shoulder area of ​​the backrest. At this time, the automatic inflation device inflates the left airbag 4, increasing its inflation height and thus increasing the support height of the left side of the backrest to accommodate the left side posture of the backrest and compensate for the distance the left side of the person's shoulder moves away from the backrest. Simultaneously, the automatic deflation device releases the right airbag 4, decreasing its inflation height and thus decreasing the support height of the right side of the backrest to accommodate the right side posture of the backrest. This ensures that the shoulder area of ​​the backrest fully conforms to the person's shoulder when turning right, reducing the risk of injury.

[0041] When the vehicle brakes suddenly, the occupant's shoulders will lift off the backrest. At this time, the automatic inflation device inflates all air bags 4, increasing their inflation height. Correspondingly, the support height of the shoulder area of ​​the backrest increases to compensate for the gap between the occupant's shoulders and the backrest, thus providing support and reducing the risk of injury. Figure 6 As shown.

[0042] In one embodiment, such asFigure 3 As shown, the air bag group includes three air bags 4, the three air bags 4 are of the same shape and size, the upper side edges of the three air bags 4 are aligned in the left-right direction of the vehicle seat, and the lower side edges of the three air bags 4 are aligned in the left-right direction of the vehicle seat. The air bags 4 are distributed regularly, so that the shape of the support surface of the backrest lifted by the air bag group is more regular, and the shoulder of the occupant can be better supported.

[0043] It can be understood that in actual application, the number, position and shape of the air bags 4 can be adjusted according to needs, for example, the air bags 4 can be arranged in two rows, and each row can be arranged with three air bags 4 in the left-right direction of the vehicle seat. The shape of the air bag 4 can be circular, oval or other shapes.

[0044] In an embodiment, the three air bags 4 are symmetrically arranged in the left-right direction of the vehicle seat.

[0045] In an embodiment, the back of the backrest foam 1 is provided with a mounting groove, the mounting groove has an opening towards the back side of the backrest foam 1, and the mounting plate 3 and the air bag 4 are placed in the mounting groove through the opening, so as to protect the air bag 4 by the flexible material of the backrest foam 1, and avoid damage to the air bag 4 by contacting sharp objects.

[0046] In an embodiment, as shown in Figure 2 The mounting groove includes a first mounting groove 11 and a second mounting groove 12, the second mounting groove 12 is located on the side of the first mounting groove 11 away from the backrest foam 1, and the opening of the second mounting groove 12 away from the backrest foam 1 is larger than that of the first mounting groove 11.

[0047] The air bag 4 is placed in the first mounting groove 11, and the mounting plate 3 is placed in the second mounting groove 12, so as to limit the movement of the mounting plate 3 to the side of the first mounting groove 11 by the bottom wall of the second mounting groove 12, and avoid the mounting plate 3 pressing the air bag 4 to the side of the backrest foam 1 when the vehicle is running, thereby affecting the normal work of the air bag 4.

[0048] In an embodiment, all air bags 4 are placed in the same first mounting groove 11, and each side wall of the first mounting groove 11 is respectively parallel to the side edge of the plurality of air bags 4. There is a set gap between the side edge of the air bag 4 and the side wall of the first mounting groove 11, so as to avoid the interference of the backrest foam 1 when the air bag 4 is inflated. Specifically, the set gap is 3mm.

[0049] In an embodiment, as shown in Figure 2 and Figure 3 The backrest framework includes a spring frame 2, and the mounting plate 3 is fixed on the spring frame 2 by a strap. Specifically, the mounting plate 3 is provided with a plurality of connection hole groups, each connection hole group includes two spaced connection holes 31, and the two ends of the strap are respectively inserted through the two connection holes 31 and bound on the spring frame 2.

[0050] In an embodiment, the air bags 4 are snap-connected to the mounting plate 3. Specifically, the air bags 4 are provided with connecting ears (not shown in the drawings), which are integrally formed on the air bags 4 and do not have the function of being inflated. The connecting ears are provided with female buckles of connecting buckles, and the mounting plate 3 is provided with male buckles of the connecting buckles. The female buckles are snap-connected to the corresponding male buckles, so as to fix the air bags 4 to the mounting plate 3.

[0051] In an embodiment, a sensor and a control box 6 are further included. The control box 6 is fixed to the spring frame 2, and the sensor is electrically connected to the control box 6. The control box 6 can control the inflator to inflate each air bag 4 individually.

[0052] The backrest foam 1 is provided with a plurality of sensors on the side facing away from the mounting plate 3. The plurality of sensors correspond to the plurality of air bags 4 one by one in the front-rear direction of the vehicle. The sensors are used to monitor the pressure of the occupant on the backrest.

[0053] The sensor has a set pressure. When the pressure detected by the sensor is greater than the set pressure, the control box 6 controls the corresponding air bag 4 to deflate, so as to reduce the inflation height of the air bag 4.

[0054] When the pressure detected by the sensor is less than the set pressure, the control box 6 controls the corresponding air bag 4 to inflate, so as to increase the inflation height of the air bag 4.

[0055] When the pressure detected by the sensor reaches the set pressure, the control box 6 controls the corresponding air bag 4 to maintain pressure, so as to keep the inflation height of the air bag 4 unchanged.

[0056] When the shoulder of the occupant leans against the shoulder area of the backrest, pressure is generated on the backrest foam 1. Therefore, the posture of each position of the shoulder of the occupant affects the pressure on the backrest foam 1. The greater the gap between the shoulder of the occupant and the backrest, the smaller the pressure of the occupant on the backrest foam 1, and the greater the inflation height of the air bag 4. In this way, the support height of the shoulder area of the backrest raised by the air bag 4 can compensate for the gap between the shoulder of the occupant and the backrest, so that the backrest can fit the shoulder of the occupant.

[0057] The set pressure is a range value, which has a minimum value and a maximum value. When the vehicle is normally driven, the pressure monitored by the sensor on the backrest is greater than the minimum value of the set pressure and less than the maximum value of the set pressure.

[0058] When the vehicle turns or brakes, the posture of each position of the person's shoulder changes, and the pressure between the person's shoulder and the corresponding sub-area of the backrest shoulder area changes. Therefore, sensors are arranged at positions corresponding to each air bag 4 on the backrest foam 1 to monitor the pressure changes borne by each sub-area of the corresponding backrest foam 1, to accurately determine the posture changes of each position of the person's shoulder, and control the increase or decrease of the inflation height of the air bag 4 with pressure changes, to correspondingly change the support height of the corresponding sub-area of the backrest, so that the shoulder area of the backrest can always fit the person's shoulder. For example, when the vehicle turns left, the right side of the person's shoulder is away from the backrest, and the pressure on the right side of the backrest shoulder area is less than the minimum value of the set pressure. Then, the inflation height of the air bag 4 is increased to increase the support height of the right side of the backrest shoulder area to fit the person's shoulder.

[0059] In an embodiment, the control box 6 is in communication with the inflation device, and a plurality of valve bodies are arranged in the control box 6, which are in one-to-one correspondence with the plurality of air bags 4. Each valve body has an inflation position, a deflation position, and a pressure maintaining position.

[0060] In the inflation position, the gas of the inflation device can flow to the corresponding air bag 4 through the valve body to increase the inflation height; in the deflation position, the gas in the corresponding air bag 4 can be deflated through the valve body to reduce the inflation height; in the pressure maintaining position, the inflation device cannot inflate the air bag 4, and the gas in the air bag 4 cannot be deflated, so that the corresponding air bag 4 can maintain pressure to keep the inflation height.

[0061] It should be noted that a controller is arranged in the control box 6, which is electrically connected with each sensor and valve body. The controller is used to determine whether the corresponding air bag 4 needs to be inflated or deflated according to the pressure detected by the sensor. When the air bag 4 needs to be inflated, the controller controls the inflation port of the corresponding valve body to open to connect the inflation device and the corresponding air bag 4. When the air bag 4 needs to be deflated, the controller controls the deflation port of the corresponding valve body to open to make the gas in the air bag 4 flow out through the deflation port of the corresponding valve body. When the air bag 4 needs to maintain pressure, the controller controls the inflation port and the deflation port of the valve body to be closed.

[0062] In an embodiment, the inflation device is a gas pump.

[0063] In an embodiment, a plurality of air tubes 5 are further included, which are arranged in one-to-one correspondence with the plurality of air bags 4. One end of each air tube 5 is in communication with the corresponding air bag 4, and the other end of each air tube 5 is in communication with the valve body corresponding to the air bag 4.

[0064] In other embodiments, the air bag 4 can have an inflation port and a deflation port, an inflation regulating valve can be provided on a pipeline connecting the inflation port and the inflation device, a deflation regulating valve can be installed at the deflation port, when the air bag 4 needs to be inflated, the inflation regulating valve is opened, when the air bag 4 needs to be deflated, the deflation regulating valve is opened, and when the air bag 4 needs to be pressure-maintained, both the inflation regulating valve and the deflation regulating valve are closed.

[0065] In addition, the utility model provides a kind of vehicle, comprising the vehicle seat in any embodiment described above.

[0066] The above-described embodiments are merely used to illustrate the technical solutions of the present application, but not to limit them; although the present application has been described in detail with reference to the foregoing embodiments, it should be understood by those skilled in the art that the technical solutions recorded in the foregoing embodiments can be modified, or some technical features can be replaced equivalently; and these modifications or replacements do not change the essence of the corresponding technical solutions, and should be included in the protection scope of the present application.
