Description

Technical Field

[0001] This utility model belongs to the field of pilot seat technology for engineering machinery, specifically relating to a pilot bracket and a pilot seat structure using the bracket. Background Technology

[0002] In the field of construction machinery, pilot valve control structures are frequently used. These structures rely on pilot supports for fixation, but existing pilot supports often lack sufficient structural strength. During prolonged, high-intensity operation, the pilot valve control structure must withstand high-pressure impacts from the hydraulic system and dynamic loads from equipment vibration. If the structural design is inappropriate or the materials are not properly selected, structural deformation and cracking can easily occur. Furthermore, because there is often a direct mechanical transmission path between the pilot valve control structure and the seat support system, when the control structure becomes unstable due to vibration, this vibration is quickly transmitted to the seat, causing the driver to experience noticeable shaking. Prolonged exposure to this environment not only exacerbates driver fatigue and reduces work efficiency but may also lead to a series of health problems. Utility Model Content

[0003] To address the problems existing in the prior art, a pilot support and a pilot seat structure using the support are proposed.

[0004] The technical solution to the technical problem solved by this utility model is as follows: On the one hand, a pilot support is proposed, including a first mounting plate and a second mounting plate arranged in parallel. The first mounting plate and the second mounting plate are connected by a vertical plate. One end of the second mounting plate is connected to a third mounting plate. The third mounting plate is higher than the second mounting plate and is inclined downward. A through groove for mounting the pilot box is opened in the middle of the third mounting plate.

[0005] Preferably, at least two sets of central reinforcing ribs are connected between the first mounting plate and the vertical plate.

[0006] Preferably, a bottom reinforcing rib is connected to the first mounting plate, the bottom reinforcing rib is V-shaped and inverted on the first mounting plate, and one end of the bottom reinforcing rib is fixed to the vertical plate.

[0007] Preferably, a top reinforcing rib is connected between the second mounting plate and the vertical plate, and the ends of the second mounting plate and the third mounting plate are connected by a connecting rib, with an outer reinforcing rib connecting the connecting rib and the third mounting plate.

[0008] Preferably, through holes are provided on both the first mounting plate and the vertical plate to reduce the weight of the bracket.

[0009] On the other hand, a pilot seat structure is proposed, in which the seat is mounted on a pilot bracket, the seat is connected to a first mounting plate, the pilot box is fixed to the bottom of a third mounting plate, and an adjustable armrest is mounted on a second mounting plate.

[0010] Preferably, the seat and the first mounting plate are connected by a first slide rail, which allows for adjustment of the distance between the seat and the pilot box; a second slide rail is connected between the bottom of the pilot bracket and the mounting area, which allows for adjustment of the overall position of the seat structure.

[0011] Preferably, the top of the third mounting plate is connected to the pilot box cover, and the pilot box cover is provided with a control button for controlling the pilot valve.

[0012] Preferably, the bottom of the seat is also equipped with a shock-absorbing layer.

[0013] Compared with existing technologies, the above technical solution has the following advantages or beneficial effects:

[0014] 1. The pilot bracket of this utility model is used to install the pilot box and the pilot box cover with control buttons on the top through a liftable handrail and an inclined third mounting plate. Its downward inclined structure is ergonomic, so that when the driver's arm is placed on the handrail, his hand can naturally fall to the control button or handle, reducing wrist fatigue caused by long-term work.

[0015] 2. This utility model strengthens the pilot support by using bottom reinforcing ribs, middle reinforcing ribs, connecting ribs and top reinforcing ribs. The reinforcing ribs are all located at stress concentration points, which makes the overall strength greater and allows the main body to use thinner plates, achieving more ideal structural strength and rigidity. This improves the driver's operating comfort and extends the overall service life of the seat during the operation of the machine. Attached Figure Description

[0023] Example 1:

[0024] Please see Figures 1-3In this embodiment, in order to strengthen the stress concentration points of the bracket, make the overall strength greater, and achieve a more ideal structural strength and rigidity, thereby improving the driver's operating comfort during the operation of the whole machine, a pilot bracket is proposed, including a first mounting plate 1 and a second mounting plate 2 arranged in parallel. The first mounting plate 1 and the second mounting plate 2 are connected by a vertical plate 4. One end of the second mounting plate 2 is connected to a third mounting plate 3. The third mounting plate 3 is higher than the second mounting plate 2 and is inclined downward. A through groove 31 for mounting the pilot box is opened in the middle of the third mounting plate 3.

[0025] After performing stress simulation analysis on the pilot bracket using software such as ANSYS, the locations of stress concentration were identified. Considering both minimizing the impact on seat 11 comfort and achieving the desired reinforcement effect, the following reinforcements were implemented:

[0026] First, connect the bottom reinforcing rib 5 to the first mounting plate 1. Two sets of bottom reinforcing ribs 5 are set symmetrically on the first mounting plate 1. The bottom reinforcing rib 5 is V-shaped and inverted on the first mounting plate 1. One end of the bottom reinforcing rib 5 is fixed to the vertical plate 4.

[0027] Secondly, a top reinforcing rib 7 is connected between the second mounting plate 2 and the vertical plate 4. At the same time, the ends of the second mounting plate 2 and the third mounting plate 3 are connected by a connecting rib 8. An outer reinforcing rib 9 is connected between the connecting rib 8 and the third mounting plate 3. The second mounting plate 2 is reinforced by the top reinforcing rib 7, the connecting rib 8 and the outer reinforcing rib 9 to resist the vibration generated by the pilot box.

[0028] Finally, at least two sets of central reinforcing ribs 6 are connected between the first mounting plate 1 and the vertical plate 4. The central reinforcing ribs 6 can improve the strength between the vertical plate 4 and the first mounting plate 1 and prevent bending. The aforementioned reinforcing ribs and connecting ribs 8 are manufactured to each mounting plate by welding or integral molding.

[0029] Both the first mounting plate 1 and the vertical plate 4 have through holes 10 to reduce the weight of the bracket, making the overall weight lighter.

[0030] Example 2:

[0031] Please see Figure 3 Based on Embodiment 1, this embodiment proposes a pilot seat structure. The seat 11 is mounted on the pilot bracket and connected to the first mounting plate 1. The pilot box is fixed to the bottom of the third mounting plate 3, and the armrests that can be raised and lowered are mounted on the second mounting plate 2.

[0032] The seat 11 is connected to the first mounting plate 1 via a first slide rail 12, which allows for adjustment of the distance between the seat 11 and the pilot box. A second slide rail 14 connects the bottom of the pilot bracket to the mounting area, allowing for overall position adjustment of the seat 11. The top of the third mounting plate 3 is connected to the pilot box cover 15, which has a control button 16 for controlling the pilot valve. The bottom of the seat 11 also has a shock-absorbing layer 13. After adjusting the position of the seat 11 and the distance between the seat 11 and the control button 16 using the first and second slide rails 12 and 14, the driver can naturally place their hand on the pilot box cover 15 when resting their arm on the armrest, making it comfortable to use.

[0033] Although the specific embodiments of the utility model have been described above in conjunction with the accompanying drawings, this is not intended to limit the scope of protection of the utility model. Based on the technical solution of the utility model, various modifications or variations that can be made by those skilled in the art without creative effort are still within the scope of protection of the utility model.
