[0025] The utility model embodiment provides an airbag shock-absorbing seat for agricultural machinery and engineering machinery.

[0026] See also Figure 4 , including a seat back body 1. The setting of the seat back body 1 can make the driver drive more comfortably, thereby ensuring that the driver is not prone to fatigue and greatly reducing the safety hazards during driving. A third resilient spring 19 is fixedly connected to one side of the inner wall of the seat back body 1. One end of the third resilient spring 19 is fixedly connected to the outer circumferential surface of the limiting positioning bead 18. The purpose of setting the third resilient spring 19 is to utilize the elasticity of the third resilient spring 19 itself to effectively push the limiting positioning bead 18 to move, thereby achieving the expected effect.

[0027] See also Figure 4 The outer circumferential surface of the limiting positioning bead 18 contacts the limiting groove 17 on one side of the limiting plug 15, and the groove on the top of the seat back body 1 is plugged with the limiting plug 15. The top of the limiting plug 15 is fixedly connected to the bottom of the head cushion body 16, and a limiting groove 17 is provided on one side of the limiting plug 15. The tight fit between the limiting plug 15 and the limiting groove 17 can effectively adjust the height of the seat back body 1.

[0028] See also Figure 1 The bottom of the seat back body 1 is fixedly connected to the top of the airbag cushion body 11, and the bottom of the airbag cushion body 11 is fixedly connected to the top of the mechanical buffer module 12. The mechanical buffer module 12 is a prior art and will not be described in detail. The setting of the mechanical buffer module 12 can freely adjust the height of the airbag shock-absorbing seat, so that the driver can find the best driving posture.

[0029] See also Figure 1 The bottom of the mechanical buffer module 12 is fixedly connected to the top of the supporting positioning plate 13. A screw hole 14 is opened in the middle of the supporting positioning plate 13. The setting of the supporting positioning plate 13 and the screw hole 14 facilitates the installation of the airbag shock-absorbing seat. One side of the seat back body 1 is fixedly connected to one side of the component protective shell 2. The setting of the component protective shell 2 protects the components inside it and makes it difficult for the components to be affected by the outside world.

[0030] See also Figure 2 The inner wall of the component protective shell 2 is fixedly connected with a positioning support module 3. There are two groups of positioning support modules 3. A guide single rod 4 is arranged between the two groups of positioning support modules 3. Both groups of positioning support modules 3 are arranged inside the component protective shell 2. The arrangement of multiple groups of positioning support modules 3 can effectively play a supporting effect and perform functional zoning.

[0031] See also Figure 2 and Figure 3A damping buffer 9 is fixedly arranged between the positioning support module 3 and the lumbar buffer pillow 7. The outer circumferential surface of the damping buffer 9 is sleeved with a second toughness spring 10. The damping buffer 9 is a prior art and will not be described in detail. The setting of the damping buffer 9 can greatly buffer the inertia of the second toughness spring 10 itself, thereby achieving a buffering effect.

[0032] See also Figure 2 One side of the positioning support module 3 is fixedly connected to one end of the guide single rod 4, and the outer circumferential surface of the guide single rod 4 is slidably connected to the groove in the middle of the buffer moving module 5. The setting of the guide single rod 4 can effectively ensure that the buffer moving module 5 can move according to the established horizontal route.

[0033] See also Figure 2 There are two groups of buffer moving modules 5, and both groups of buffer moving modules 5 slide on the outer circumferential surface of the guiding single rod 4. A first tough spring 8 is fixedly connected between the two groups of buffer moving modules 5. The setting of the first tough spring 8 utilizes the elasticity of the first tough spring 8 itself to effectively play a buffering effect and avoid collision between components.

[0034] See also Figure 2 One side of the buffer moving module 5 is rotatably connected to one end of the first linkage rod 6, and the other end of the first linkage rod 6 is rotatably connected to one side of the lumbar buffer pillow 7. The setting of the lumbar buffer pillow 7 can directly contact the driver's waist, thereby playing a supporting effect. One side of the buffer moving module 5 is fixedly connected to the first toughness spring 8, and the first toughness spring 8 is sleeved on the outer circumferential surface of the guide single rod 4. The cooperation between the guide single rod 4 and the first toughness spring 8 can ensure the stability of the movement of the components and prevent the components from deviating easily.

[0035] Working principle: First, the driver sits on the airbag cushion body 11, with his back against the seat back body 1, and changes the height of the mechanical buffer module 12 through external power, thereby adjusting the optimal posture. Then, the head cushion body 16 is moved by external force. At this time, the limiting insert 15 slides in the seat back body 1, so that the limiting positioning bead 18 enters the specified limiting groove 17. The third toughness spring 19 completes the fixation of the head cushion body 16 under its own elastic effect. At this time, the lumbar buffer pillow 7 will support the driver's lumbar position, and when the driver is bumped, the lumbar The buffer pillow 7 slides in the component protective shell 2, so that the first linkage rod 6 drives the buffer movable module 5 to slide on the guide single rod 4. At this time, the two groups of buffer movable modules 5 compress the first resilient spring 8. Under the elastic action of the first resilient spring 8 itself, it effectively plays a buffering effect. At the same time, the lumbar buffer pillow 7 will also compress the damping buffer 9, so that the second resilient spring 10 will contract. Under the joint action of the damping buffer 9 and the second resilient spring 10, the buffering effect is further strengthened, thereby effectively supporting the driver's waist and alleviating the fatigue of the driver's waist.

[0036] The above shows and describes the basic principle and main features of the utility model and the advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only for explaining the principle of the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, which fall within the scope of the utility model to be protected. The scope of protection claimed by the utility model is defined by the attached claims and their equivalents.
