[0002] The heavy truck driver's seat is a key equipment designed for heavy truck drivers who drive long distances. It plays a vital role in ensuring the driver's comfort and safety.

[0003] With the continuous development of the logistics and transportation industry and the increasing attention paid to the driver's working environment, heavy-duty truck drivers often need to drive for long periods of time. Traditional seats lack the function of limiting support for heavy-duty truck drivers on both sides, and thus cannot stabilize the driver's body when the vehicle turns or is impacted from the side, causing the driver to tilt excessively and be unable to maintain body balance. However, if a simple limit stabilization device is added, when it needs to be inspected and maintained during long-term use, it cannot achieve good disassembly operation efficiency, reducing the practicality of the device.

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0019] The present invention provides the following technical solutions: Embodiment 1 Combination Figures 1 to 5 A heavy truck driver seat chassis capable of automatically adjusting the inflation volume and pressure of an airbag comprises a support seat 1, a side cushion 2 is arranged outside the support seat 1, an inflation mechanism 4 is arranged inside the side cushion 2, and a maintenance mechanism 3 is arranged outside the side cushion 2; The maintenance mechanism 3 includes a fixed groove 31, which is fixedly connected to the outer side of the side pad 2, and a movable block 32 is movably connected to the inner wall of the fixed groove 31, a support box 33 is fixedly connected to one side of the fixed groove 31, a spring 35 is fixedly connected to the inner wall of the support box 33, a slider 34 is fixedly connected to one end of the spring 35, a clamping shaft 301 is fixedly connected to one side of the slider 34, a pull rod 36 is fixedly connected to the side of the slider 34 away from the clamping shaft 301, and a pull plate 37 is fixedly connected to the end of the pull rod 36 away from the slider 34, a limiting plate 38 is fixedly connected to the outer side of the side pad 2, and a partition plate 39 is fixedly connected to the inner side of the movable block 32.

[0020] Furthermore, a through hole is formed on one side of the support box 33 away from the fixing groove 31 , and the pull rod 36 passes through the through hole, so that the pull rod 36 can move through the through hole.

[0021] Furthermore, the slider 34 is slidably connected to the inner wall of the support box 33 , and the spring 35 is fixedly connected to one side of the slider 34 , so that the slider 34 can stably move to compress the spring 35 .

[0022] Furthermore, a moving hole is provided at the bottom of the fixing groove 31 , and the card shaft 301 passes through the moving hole, so that the card shaft 301 can move through the moving hole.

[0023] Furthermore, a clamping hole is provided on one side of the movable block 32 , and the clamping shaft 301 is movably connected to the inner wall of the clamping hole, so that the clamping shaft 301 can limit the movable block 32 through the clamping hole.

[0024] The clamping shaft 301 is movably connected to one side of the side pad 2 .

[0025] Embodiment 2 See also Figures 1 to 5 On the basis of the first embodiment, the inflation mechanism 4 further comprises an air cylinder 41, the air cylinder 41 is fixedly connected to the inner wall of the side cushion 2, one side of the air cylinder 41 is fixedly connected to an air intake pipe 45, one end of the air intake pipe 45 is fixedly connected to an air intake valve 46, the top of the air cylinder 41 is fixedly connected to an exhaust pipe 42, the top of the exhaust pipe 42 is fixedly connected to an exhaust valve 43, the top of the side cushion 2 is movably connected to an airbag 44, the inner wall of the side cushion 2 is fixedly connected to a processor 48, and the top of the support seat 1 is fixedly connected to a pressure sensor 47, so as to facilitate the purpose of inflating the airbag 44.

[0026] Furthermore, the exhaust valve 43 and the intake valve 46 are both fixedly connected to the bottom of the airbag 44 to achieve the purpose of inflating and exhausting the airbag 44.

[0027] In actual operation, when this device is used, the driver can first sit on the top of the support seat 1, and then the pressure applied by the driver to the support seat 1 can be detected at any time through the pressure sensor 47. When a certain pressure deviation occurs on one side, either the front side or the rear side, the pressure sensor 47 can send a signal to the processor 48, and then the air bag 44 can be inflated through the cooperation of the intake valve 46 and the intake pipe 45, so that the air bag 44 can block the driver. When the vehicle turns, the centrifugal force will cause the driver's body to tilt to one side. At this time, the side air bag 44 can increase the inflation amount according to the signal of the pressure sensor 47 to prevent the driver from excessively tilting and maintain the body balance.

[0028] Then, during long-term use, when it is necessary to inspect and maintain the parts inside the support seat 1, the pull plate 37 can be pulled first to drive the pull rod 36 to move, so that the pull rod 36 can pull the card shaft 301 out of the interior of the movable block 32 through the slider 34, and the limit on the movable block 32 is cancelled. At the same time, the slider 34 can compress the spring 35. When the card shaft 301 is completely moved out of the interior of the movable block 32, the pull plate 37 can be rotated to make a circular motion along the axis point of the pull rod 36, so that the pull plate 37 can be stuck on one side of the limit plate 38 to limit the pull plate 37. At this time, the card shaft 301 cannot be limited by the spring 35. At this time, the movable block 32 can be pulled out from the interior of the fixed groove 31 through the partition plate 39, and the partition plate 39 can be disassembled, which is convenient for the inspection and maintenance of the internal parts of the side pad 2. At the same time, good operation and disassembly efficiency can be achieved, further improving the convenience of device operation.
