The present invention will be described in detail below with reference to the accompanying drawings in conjunction with embodiments.
Example one
The present embodiment relates to a vehicle seat comfort adjusting apparatus that is provided on a vehicle seat, and as shown in fig. 1, the vehicle seat comfort adjusting apparatus integrally includes body pressure collecting means 1 for collecting body pressure distribution of a seated person on the seat, an adjustment actuator 2 that is constituted by a lumbar support air bag 201, a side wing support air bag 202, and a shoulder support air bag 203 provided on the vehicle seat, and a control module 3 having a control module 301 and a control valve module 302.
Specifically, as an implementation form, the body pressure acquiring mechanism 1 of the present embodiment employs a plurality of massage air bags 101 distributed on the backrest of the vehicle seat, and it should be noted that the main point of the comfort adjusting device of the present embodiment is to use the existing backrest massage air bag assembly installed on the vehicle seat as the main body part of the body pressure acquiring mechanism 1, and use the existing side wing or shoulder air bag support installed on the vehicle seat and waist support air bag support as the main body part of the adjusting actuator 2, thereby achieving the purpose of reducing the overall cost of the adjusting device.
In this embodiment, a first air pressure sensor 102 is also provided corresponding to each massage air bag 101 to detect the air pressure in the corresponding air bag. The distribution of the massage air bags 101 on the backrest can be directly referred to the existing backrest massage air bags applied to the vehicle seat, and generally, for example, the massage air bags 101 can be arranged in two rows, four rows or other numbers on the backrest, a plurality of massage air bags 101 are arranged in each row at intervals from top to bottom, and the massage air bags 101 in each row are arranged on the backrest of the seat at intervals along the left and right directions of the backrest so as to be capable of contacting with two side parts of the body of the occupant. Meanwhile, when four rows are adopted, the number of the two rows of massage air bags 101 positioned in the middle can be more than that of the two rows positioned at the two sides, so that the massage air bags are better matched with the human body shape.
In this embodiment, the massage airbag 101 is generally disposed between the face mask layer and the foaming layer of the seat back, but it can be disposed at other positions of the seat back according to the specific design requirement. In addition, because the body pressure acquisition mechanism with each massage air bag 101 can directly adopt the existing backrest massage air bag assembly, the air source of the massage air bag 101 can still be provided by the relevant control part for massage control, and the adjusting device of the embodiment obtains the air pressure in each massage air bag 101 through the first air pressure sensor 102 correspondingly arranged, so as to obtain the body pressure distribution condition of the passengers.
However, as a possible implementation manner in this embodiment, it is understood that each massage airbag 101 can also supply air through the control mechanism 3, and specifically, the massage airbag 101 is also connected to the control valve module 302, and the related massage control portion can be integrated into the control module 301 of the control mechanism 3, so as to achieve the massage effect of the massage portion formed by each massage airbag 101 through the control of the control module 301 on the operation of the control valve module 302.
The first air pressure sensor 102 and the second air pressure sensor 204 mentioned below in this embodiment may be implemented by using commercially available suitable air pressure sensing components, and the first air pressure sensor 102 corresponding to each massage air bag 101 in the body pressure collecting mechanism 1 and the second air pressure sensor 204 corresponding to each air bag in the adjustment actuator 2 may be disposed at the air path connected to each air bag. Alternatively, when the air supply of each massage air bag 101 is also controlled by the control means 1, the first air pressure sensor 102 or the second air pressure sensor 204 corresponding to each air bag may be integrated with the control valve module 302.
At this time, by applying the first air pressure sensor 102 and the second air pressure sensor 204, the present embodiment can utilize the principle of the communicating vessels that the air pressure in the massage air bag 101 is substantially the same as the air pressure in the pipeline, so that only the air pressure sensor is needed to be disposed at the air passage or the control valve module 302, the change of the air pressure value can be measured, and the change of the air pressure value corresponds to the change of the physical pressure of the occupant borne by the seat. Therefore, when the body pressure of a passenger is acquired, the existing pressure pad structure is not required to be designed, a special signal wire is not required to be arranged from a sensor in an air bag to the control module, and the air pipe at the moment is equivalent to the original signal wire, so that the whole body pressure detection structure can be greatly simplified, and the defects of high cost and inconvenient implementation of the existing pressure pad needing wiring are overcome.
It should also be noted that the massage airbag 101 forming the body pressure detecting mechanism 1 may be provided on the seat cushion of the seat at the same time as another possible embodiment, in addition to being disposed on the backrest of the seat. In this case, the massage airbags 101 on the seat cushion can be generally directly used as seat cushion massage airbags conventionally used in vehicle seats, and the massage airbags 101 on the seat cushion can be arranged in two rows. Alternatively, it may be provided in other numbers than two rows, and the specific arrangement of the massage airbags 101 on the seat cushion may be made with reference to the arrangement of the massage airbags 101 on the backrest.
As described above, the adjustment actuator 2 of the present embodiment employs the lumbar support air bag 201, the side wing support air bag 202 and the shoulder support air bag 203 which are disposed on the vehicle seat, and the second air pressure sensors 204 which detect the air pressure in the respective air bags are respectively disposed in the present embodiment corresponding to the lumbar support air bag 201, the side wing support air bag 202 and the shoulder support air bag 203.
In this case, since the conventional side flap or shoulder bag support and lumbar support bag support can be used for the lumbar support bag 201, the side flap support bag 202 and the shoulder support bag 203 in the adjustment mechanism 2, the arrangement of the respective support bags on the vehicle seat can be found in the related arrangement in the related art.
In addition, it should be noted that, in general, the lumbar support airbag 201 may be disposed at the rear side of the foamed layer of the backrest, and the side flap support airbag 202 may include a cushion side flap support airbag and a backrest side flap support airbag, so as to provide better side support effect.
In this embodiment, the control module 301 of the control mechanism 3 is electrically connected to each of the first air pressure sensor 102, each of the second air pressure sensor 204, and the control valve module 302 can be connected to the external air source and each of the air bags. Meanwhile, in terms of overall design, the control module 301 of the present embodiment is also configured to control the control valve module 302 to operate based on the collected data of each first air pressure sensor 102, so as to adjust the air pressure of each air bag in the adjusting actuator 2.
The control module 301 may generally adopt a programmable controller, and for example, may adopt an existing single chip or other vehicle-mounted programmable control devices. The control valve module 302 may be implemented by using an existing solenoid valve, and may be provided with control valves corresponding to the air bags, or may be implemented by using one or more solenoid valve sets to control the air bags in each mechanism.
In addition, in the embodiment, the external air source may be a pressurized air source disposed on the vehicle, so that the adjusting device and other air-using components in the vehicle share the air source. However, as a possible embodiment, the control mechanism 3 of the present embodiment may also be provided with the air pump 303 that constitutes the above-described external air supply, so that the air supply is provided by the specially arranged air pump 303. The air pump 303 is generally installed and fixed in the frame of the seat.
When the comfort adjustment device of this embodiment is used, after a rider sits on the seat, the air pressure value of each massage air bag 101 with a certain pre-air pressure changes, and each first air pressure sensor 102 sends the acquired air pressure signal to the control module 301. The control module 301 controls the action of the control valve module 302 according to the preset pressure signals, so that the air pressures in the waist support supporting air bag 201, the side wing supporting air bag 202 and the shoulder supporting air bag 203 are adjusted according to needs, and the body pressure distribution of a rider is uniform by changing the molded surface or hardness of the relevant part of the seat, so that the seat body pressure distribution of comfort is realized, and the riding comfort is improved.
Meanwhile, after the pressure variation data of each massage air bag 101 on the seat is acquired by the body pressure acquiring mechanism 1, since the height and the weight of a general human body are linearly related to the air pressure value of each massage air bag 101, for example, passengers can be classified by using the existing machine learning algorithm based on the data. After the height and the weight of the passenger are obtained, the motion envelope diagram of the seat can be utilized, corresponding designed sitting positions of the human body in the envelope diagram exist on the basis of different percentages, and further, a better comfortable and safe position of the seat is obtained according to the overall arrangement of the seat, so that the seat can be automatically adjusted. These can also enrich the application of this embodiment adjusting device to a certain extent, and be favorable to promoting vehicle seat's performance.
