The specific meaning of the above terms in the embodiments of the present invention can be understood in specific cases by those skilled in the art.
Referring to fig. 1, the present invention provides an engineering machine, which includes a body and a seat 50, wherein the seat 50 is mounted on the body. The number of the seats 50 may be one or two, and is not limited herein, and the working machine may be, but is not limited to, an excavator, a loader, a forklift, and the like.
With respect to the seat 50, the seat 50 includes a body 510 and a seat rigidity adjusting mechanism 520, and the seat rigidity adjusting mechanism 520 is connected to the body 510 and is used to adjust the rigidity of the seat 50.
The seat stiffness adjusting mechanism 520 comprises a mass sensor 10 and an adjusting mechanism 30, wherein the mass sensor 10 is arranged on the seat 50 and used for detecting the gravity value of the driver; the adjusting mechanism 30 comprises an air bag 310 arranged below the seat 50 and supporting the seat 50 and an air pressure adjusting mechanism 320 connected with the air bag 310, wherein a first pressure sensor 3110 is arranged in the air bag 310 and used for detecting the pressure value in the air bag 310 so as to obtain the supporting force of the air bag 310 on the seat 50; the air pressure adjusting mechanism 320 is configured to inflate and deflate the air bag 310, so that a difference between a supporting force of the air bag 310 on the seat 50 and a corresponding gravity value detected by the mass sensor 10 is within a preset range.
It should be noted that different pressure values in the air bag 310 correspond to different support forces for the seat 50, and the gravity value of the driver detected by the mass sensor 10 is compared with the support force of the air bag 310 for the seat 50, and the pressure value in the air bag 310 is adjusted to suit different drivers.
Compare in the tradition through the manually-operated machine class regulation seat 50 rigidity, the embodiment of the utility model provides an utilize atmospheric pressure adjustment mechanism 320 to aerify gasbag 310, and then make gasbag 310 to seat 50's holding power and the difference between the driver's the gravity value that quality sensor 10 detected out at predetermineeing the within range, so make the driver be in a more comfortable supporting rigidity when taking seat 50, improve driver's the experience of taking. Compared with an air spring, the air spring has the advantages that the air bag 310 is adopted, the contact area between the air bag 310 and the seat 50 is larger, the supporting effect is better, and in the inflating and deflating processes, the deformation speed of the air bag 310 is low, so that a good buffering effect is achieved.
Specifically, a data acquisition mechanism 60 is also included and is in communication with the mass sensor 10. It should be noted that the first pressure sensor 3110 is also in communication with the data acquisition mechanism 60. The communication connection mode can be wired or wireless connection, and wireless connection is not limited to Bluetooth communication connection. The data acquisition unit 60 acquires and compares the gravity value of the driver detected by the mass sensor 10 and the pressure value in the airbag 310 detected by the first pressure sensor 3110. The different pressure values may serve as different support forces for the seat 50, i.e. the support forces may be compared with the driver's gravity values. For example, the preset range is set to a driver gravity value of 2.5 kg floating up and down. The airbag 310 may be inflated in advance to an initial set value, and the initial set value is equivalent to 60 kg of the driver's weight. When the weight of the driver is less than 57.5 kg, the air bag 310 is deflated until the weight which can be supported by the supporting force is between 57.5 kg and 62.5 kg. If the weight of the driver is greater than 62.5 kg, the airbag 310 may be inflated until the support force is between 57.5 kg and 62.5 kg. This automatically adjusts the rigidity of the seat 50, thereby improving the comfort of the driver.
The air pressure adjusting mechanism 320 comprises an electromagnetic valve 3210 and an air storage tank 3220; one end of the electromagnetic valve 3210 is communicated with the air bag 310 through an air pipe, the other end is communicated with the air storage tank 3220 through an air pipe, and the air storage tank 3220 is used for inflating the air bag 310 through the electromagnetic valve 3210.
Specifically, the solenoid valve 3210 includes a first position, a second position, and a third position; when the electromagnetic valve 3210 is in the first position, the air storage tank 3220 is in a communication state with the air bag 310; when the electromagnetic valve 3210 is at the second position, the air storage tank 3220 and the air bag 310 are in a check state, and the air bag 310 is communicated with the outside; when the electromagnetic valve 3210 is in the third position, the air reservoir 3220 and the air bag 310 are in a check state, and the air bag 310 is not communicated with the outside.
That is, when the difference between the supporting force equivalent to the pressure value detected by the first pressure sensor 3110 and the gravity value detected by the mass sensor 10 is smaller than the preset range, it indicates that the seat 50 is better matched with the airbag 310 at this time, and the airbag 310 does not need to be inflated or deflated; when the difference between the supporting force equivalent to the pressure value detected by the first pressure sensor 3110 and the gravity value detected by the mass sensor 10 is greater than the preset range, the air bag 310 needs to be inflated or deflated so that the difference between the supporting force of the seat 50 by the air bag 310 and the gravity value detected by the mass sensor 10 returns to the preset range again.
In some embodiments of the present invention, the air pressure adjusting mechanism 320 further includes an air pump 3230, the air pump 3230 is communicated with the air storage tank 3220 through an air pipe; a second pressure sensor 3240 is provided in the air reservoir 3220. It is to be appreciated that a second pressure sensor 3240 is also communicatively coupled to the data acquisition mechanism 60. That is, after the air bag 310 is inflated for a plurality of times, the pressure in the air tank 3220 is reduced, when the pressure value in the air tank 3220 received by the data acquisition mechanism 60 is lower than the lowest value, the air pump 3230 starts to operate, the external air is compressed, the high-pressure air is charged into the air tank 3220, and when the internal pressure value in the air tank 3220 reaches the designed highest value, the air pump 3230 stops operating.
Further, a check valve 3250 is connected between the air pump 3230 and the air storage tank 3220, and a pressure relief valve 3221 is disposed at the top of the air storage tank 3220. That is, the air pump 3230 charges the air storage tank 3220 through the check valve 3250, and the air in the air storage tank 3220 does not flow back to the air pump 3230 side, and when the internal pressure of the air storage tank 3220 rises to a safe value due to external factors such as high temperature, the pressure relief valve 3221 is automatically opened to relieve the pressure of the air storage tank 3220, so that the safe operation of the system is maintained.
It should be noted that the communication and control modes between the data acquisition mechanism 60 and the first pressure sensor 3110, the second pressure sensor 3240, and the mass sensor 10 belong to technical means well known to those skilled in the art, and are not described herein again. The data acquisition mechanism 60, the first pressure sensor 3110, the second pressure sensor 3240, and the mass sensor 10 are all products that are directly available on the market, and no change is made to the internal program.

That is, the shock absorbers 40 under the seat 50 can absorb the air in/out of the air bags 310 and the vibration transmitted from the cab. And for a driver whose weight exceeds the initial load-bearing capacity of the air bag 310, the shock absorber 40 can effectively avoid a large deformation of the seat 50 in a short time.
The installation angle of the damper 40 may be, but not limited to, 90 degrees, or may be set to 30 degrees, 45 degrees, or 60 degrees according to a space, which is not limited herein.
The number of the dampers 40 may be not limited to one, two, four, etc., and the installation position is not limited to the middle of the seat 50, and may be set at four corners or diagonal positions of the seat 50 according to actual requirements, which is not limited herein.
