Description

Technical Field

[0001] The utility model relates to the technical field of aviation machinery, and in particular to a back pad structure. Background Art

[0002] Aviation refers to the flight (navigation) activities of aircraft in the earth's atmosphere (air space). Aircraft engaged in flight activities are also called aircraft. They are divided into two categories: lighter-than-air aircraft and heavier-than-air aircraft. The former, such as balloons and airships, use the static buoyancy of air to get into the air, while the latter, such as airplanes and helicopters, use aerodynamics to get into the air. A back cushion is something that a person's back can lean against and feel comfortable when sitting for a long time.

[0003] An aviation seat cushion is provided by the existing patent publication number CN216154048U. When a passenger leans on the aviation seat cushion provided by the embodiment of the utility model, the passenger's back applies pressure to the cushion. At this time, the pressure sensor is squeezed, and then the pressure sensor senses the pressure value. At this time, the controller controls the telescopic device to start working, and the telescopic device drives the elastic column arranged at its working end to move up and down. The pressure sensor senses the pressure value in real time during the movement of the above-mentioned telescopic device. When the above-mentioned sensed pressure value is the smallest, it proves that the elastic column is in the best supporting position. The aviation seat cushion provided by the embodiment of the utility model can achieve the technical effect of adaptively finding the best supporting position according to the height of different users, thereby improving riding comfort.

[0004] The above scheme has the following problems during implementation: in order to facilitate the technical effect of adaptively finding the best support position according to the height of different users, the back cushion of the device is provided with an elastic column that can be moved up and down to improve riding comfort. However, the elastic column in the device is fixed and not convenient to replace. After long-term use, the elasticity of the elastic column is likely to decrease or even become concave, thereby affecting the comfort and greatly reducing the practicality of the device. For this reason, we provide a back cushion structure to solve the above problems. Utility Model Content

DETAILED DESCRIPTION

[0022] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0023] like Figure 1 , Figure 2 and Figure 3 As shown, the utility model provides a technical solution: a back cushion structure, including a cushion body 1, the outer side of the cushion body 1 is wrapped with a soft wrapping 2, and an elastic column 3 is arranged in the soft wrapping 2, a pressure sensor 31 is installed on the surface of the elastic column 3, a power supply 11, a controller 12 and a telescopic device 5 are installed on the lower side of the cushion body 1, the elastic column 3 is installed on the top of the telescopic device 5, a moving component 4 is installed on one side of the cushion body 1, the moving component 4 includes a support rod 1 41 and a support rod 2 42, and the support rod 1 41 and the support rod 2 42 are both installed on both sides of the cushion body 1, and the surfaces of the support rod 1 41 and the support rod 2 42 are respectively slidably sleeved with a sliding sleeve 1 43 and a sliding sleeve 2 44, the elastic column 3 is fixed to the sliding sleeve 1 43 and the sliding sleeve 2 44 through a disassembly component 6, the device can automatically adjust the position of the elastic column 3 according to the height of different users, and adaptively find the best supporting position, so that the back is more comfortable when leaning.

[0024] It should be noted that the power supply 11 and the controller 12 are both electrically connected to the pressure sensor 31, the power supply 11 and the controller 12 are both electrically connected to the telescopic device 5, and the power supply 11 and the controller 12 are electrically connected to each other, so that the elastic column 3 can be better controlled to be adjusted to a suitable position. In addition, the power supply 11, the controller 12, the pressure sensor 31 and the telescopic device 5 are all prior arts in an aviation seat cushion in a comparative document.

[0025] As an implementation method in this embodiment, Figure 3 and Figure 4 As shown, a zipper 21 is installed at the side end of the soft package 2. In order to open the soft package 2 and facilitate the disassembly of the elastic column 3 inside, a disassembly mechanism for replacing the elastic column 3 is installed between the side end of the elastic column 3 and the moving component 4. The disassembly mechanism includes a disassembly component 6 for disassembling the elastic column 3 and a limiting component 7 for fixing the elastic column 3. The disassembly component 6 includes a connecting block 1 61, a connecting block 2 63, a limiting rod 65 and a limiting component 7. The connecting block 1 61 and the connecting block 2 63 are fixedly connected to the sliding sleeve 1 43 and the sliding sleeve 2 44 respectively. One end of the connection block 1 61 and the connection block 2 63 is respectively provided with a slot 1 62 and a socket 64, a limiting rod 65 is fixedly connected to the side end of the elastic column 3, the limiting rod 65 passes through the socket 64 and is inserted into the slot 1 62, and the limiting rod 65 is fixed by the limiting assembly 7. This structure allows the elastic column 3 to be disassembled, thereby facilitating the replacement of the elastic column 3. In this way, when the elasticity of the elastic column 3 is reduced or a depression occurs, the elastic column 3 can be better maintained, so that the comfort of the device can be better maintained, which greatly increases the practicality of the device. Figure 5As shown, the limiting assembly 7 includes a fixed block 71, and a slide groove 72 is fixedly connected to the sliding sleeve 44. A slide groove 72 is opened at one end of the fixed block 71, and springs 73 are installed on the upper and lower sides of the slide groove 72. A slider 74 is slidably installed at the opening of the slide groove 72. The two ends of the spring 73 are respectively connected to the inner wall of the slide groove 72 and the inner end of the slider 74. This structure allows the limiting rod 65 to be limited, so that the elastic column 3 is installed more firmly and not easy to shake. In this way, the elastic column 3 is also more stable when moving. Figure 5 As shown, one end of the slider 74 is fixedly connected to a shift block 75, and the outer wall of the fixed block 71 is provided with a guide opening 76, and the shift block 75 slides in the guide opening 76. This structure makes it more convenient to drive the slider 74 to slide in the slide groove 72 by shifting the shift block 75.

[0026] As an implementation method in this embodiment, Figure 3 and Figure 6 As shown, a disassembly component 8 for disassembly is installed between the bottom end of the elastic column 3 and the telescopic device 5. The disassembly component 8 includes a connecting tube 81, and the connecting tube 81 is connected to the elastic column 3. A slot 82 is provided on the outer wall of the connecting tube 81. A connecting rod 51 is connected to the upper side of the telescopic device 5, and the connecting rod 51 is inserted into the slot 82. The outer diameter of the connecting rod 51 matches the inner diameter of the slot 82, so that the connecting rod 51 is not easy to shake after being inserted into the slot 82. A movable groove 83 and a second slot 84 are respectively provided on both sides of the inner wall of the slot 82. An arc block 85 is slidably installed in the movable groove 83, and the arc block 85 is inserted into the second slot 84. This structure makes it possible to install the telescopic device 5 of the elastic column 3, so that the telescopic device 5 is more stable when driving the elastic column 3 to move longitudinally. The elastic column 3 and the telescopic device 5 can also be disassembled, so that it is easier to disassemble the elastic column 3. Figure 6 As shown, the surface of the arc block 85 is connected to a second shifting block 86 , and the inner wall of the movable groove 83 is provided with a second guide opening 87 , in which the second shifting block 86 slides, making it more convenient to drive the arc block 85 to slide by shifting the second shifting block 86 .

[0027] Working principle: If it is necessary to disassemble the elastic column 3 for replacement, it is only necessary to open the zipper 21 first, then toggle the second shift block 86 to slide in the second guide opening 87, the second shift block 86 drives the arc block 85 to be pulled out from the second slot 84 and slide into the movable slot 83, and then toggle the first shift block 75 to slide in the first guide opening 76, the first shift block 75 drives the slider 74 to slide in the slide slot 72 to compress the spring 73 until the slider 74 is completely moved into the slide slot 72, so that the elastic column 3 can be lifted up first, so that the elastic column 3 drives the connecting tube 81 to move upward until the connecting rod 51 is moved out of the slot 82, and finally the elastic column 3 is pulled horizontally, and the elastic column 3 drives the limiting rod 65 to slide out of the slot 1 62 and the plug hole 64 in turn, until the soft package 2 in the elastic column 3 is taken out, so that the disassembly of the elastic column 3 can be completed, and the replacement of the elastic column 3 is realized, which greatly increases the practicality of the device;

[0028] In addition, when the passenger leans on the soft package 2, the passenger's back applies pressure to the elastic column 3. At this time, the pressure sensor 31 is squeezed, and then the pressure sensor 31 senses the pressure value. At this time, the power supply 11 provides electricity, and the controller 12 controls the telescopic device 5 to start working. The telescopic device 5 drives the elastic column 3 set at its working end to move up and down. At this time, the elastic column 3 will also drive the sliding sleeve 1 43 and the sliding sleeve 2 44 to slide on the support rod 1 41 and the support rod 2 42. The pressure sensor 31 senses the pressure value in real time during the movement of the above-mentioned telescopic device 5. When the above-mentioned sensed pressure value is the smallest, it proves that the elastic column 3 is in the best supporting position. In this way, the technical effect of adaptively finding the best supporting position according to the height of different users can be achieved, thereby improving riding comfort.

[0029] The above embodiments are only used to illustrate the technical solution of the present invention, but not to limit it.
