Embodiment Construction
[0027]The present invention will be further described below with reference to the accompanying drawings and examples:
[0028]Such asfigure 1 withfigure 2 As shown, the present invention has a suction type mount mower rollover protection structure, including the frame 1, and the left and right sides of the frame 1 are respectively mounted, the left column 2 and the right column 3, the left column 2 and the right column 3 The top end is fixedly welded, and the connector 4 of the connecting member 4, the top end of the left column 2 and the right column 3 is fixed to the two ends of the bolt and the cross beam 5, and the two sides of the beam 5 are fixedly mounted with a buffer capsule 6. The lower ends of the left column 2 and the right column 3 are fixedly welded to have a self-locking buffer sublele, and the self-locking buffer suction energy absorber 7 is welded to the frame 1 on one side of the column;
[0029]Such asimage 3 ,Figure 4 withFigure 10As shown, the buffer capsule 6 include...

The invention discloses a rollover protection structure for an energy-absorbing mount type lawn mower, which includes a vehicle frame. Left and right columns are respectively installed on the left and right sides of the vehicle frame, and connecting pieces are fixedly welded on the tops of the left and right columns. , the connectors at the top of the left column and the right column are fixedly connected to the two ends of the beam through bolts to form a frame structure. The two sides of the beam are symmetrically fixed with buffer energy absorbers, and the lower ends of the left column and the right column are fixed and welded with self-locking The buffer energy absorber, the side of the self-locking buffer energy absorber away from the column is welded on the vehicle frame. When the riding lawn mower rolls over during operation, the energy absorbers at the left and right ends of the ROPS beam can absorb the impact energy generated when the ROPS contacts the ground, and the two self-locking energy absorbers can As the rollover protection device hits the ground and slides along slopes, it continuously tightens and absorbs energy, dampening vibrations to reduce driver injury.
Description
Technical field[0001]The present invention relates to a rollover protection structure, and in particular to a suction type mount mower rollover protection structure.Background technique[0002]When mounting the mowers in a complicated environment such as slopes, depression, due to the changes in the center of gravity, it is easy to cause rollover accidents, seriously threatening the driving safety of the driver. From the perspective of protecting the safety of the driver, install the roll-overprotective structure (ROPS) on the mounting mower, avoiding the safe living space of the driver in the ground or vehicle other part of the rollover accident (DEFOTION LimitingVolume) DLV) pose a threat to the driver's life. At the same time, when the turning protection structure is satisfied with strength, stiffness requires a certain amount of resistance to avoid fatal injuries under impact load. However, the difficulty of turning the protective structure design is contradictory in load capacity...
