Description
Technical field
The present invention relates to support rod of engine hood, refer to particularly a kind of can self-align support rod of engine hood structure.
Background technology
Support rod of engine hood is to realize the supporting mechanism that car bonnet is opened.General car bonnet is opened needs bimanualness, and people needs directly contact bonnet stay could realize car bonnet unlatching.Because strut is placed in machinery space inside, the variation of machinery space and ambient temperature is very large on strut impact, and during operation, easily occurring danger can affect personal safety and operation comfort, comfort feature.
Summary of the invention
Object of the present invention will overcome the existing deficiency of prior art exactly, provide a kind of can self-align support rod of engine hood structure.
For achieving the above object, what the present invention was designed can self-align support rod of engine hood structure, comprise the first strut and be socketed in the second strut outside the first strut, in described the first strut, be provided with the ratchet of rotation, in described the second strut, be fixedly installed the S. A. that can rotate for ratchet, on the side of described the first strut, be provided with the guide groove moving relative to the second strut for S. A., described S. A. is through ratchet, and the two ends of described S. A. are fixed in described the second strut through guide groove, on described the first strut and the second strut, be respectively arranged with interlocking slot and the outer locked groove of being convenient to described ratchet rotation and locking, in described the first strut, be provided with the pushing block that promotes ratchet rotation.
In such scheme, described pushing block comprises the first pushing tow face and the second pushing tow face, between described the first pushing tow face and the second pushing tow face, is provided with the contact surface that can contact with ratchet.Like this, the flank of tooth that promotes ratchet by pushing block rotates, thereby realizes the rotation, self-align and remove self-align of ratchet.
In such scheme, the outer rim of described ratchet is provided with two groups of relative gear teeth, and every group of gear teeth comprise the draw-in groove between two teeth and two teeth.Preferably, described draw-in groove is " V " type.
In such scheme, described interlocking slot and outer locked groove are strip shape, and described interlocking slot is arranged on the top of the first strut, and described outer locked groove is arranged on the top of the second strut, and described outer locked groove is fitted in the outside of interlocking slot, and are positioned at the top of described guide groove.Preferably, the cross sectional shape of described the first strut and the second strut is rectangle or circle.Like this, ratchet when rotation, can so that from interlocking slot and locked groove eject, thereby realize self-align.
Beneficial effect of the present invention is: by pushing block, to realize the rotation of ratchet and self-align, can remove the self-align of ratchet, thereby realize the object that car bonnet is opened or closed simultaneously.Of the present invention simple and reliable for structure, easy-to-operate, can realize one-handed performance.

The specific embodiment
Below in conjunction with the drawings and specific embodiments, the present invention is described in further detail.
Can self-align support rod of engine hood structure shown in Fig. 1, comprise the first strut 1 and be socketed in the second strut 3 outside the first strut 1, cross sectional shape is rectangle.
Shown in Fig. 2, in the first strut 1, be provided with on the side that is fixedly installed S. A. 4, the first struts 1 that can rotate for ratchet 2 in ratchet 2, the second struts 3 of rotation and be provided with the guide groove 1.1 moving relative to the second strut 3 for S. A. 4.S. A. 4 is through ratchet 2, and the two ends of S. A. 4 are fixed in the second strut 3 through guide groove 1.1, on the first strut 1 and the second strut 3, be respectively arranged with and be convenient to be provided with the pushing block 5 that promotes ratchet 2 rotations in the interlocking slot 1.2 of ratchet 2 rotation and outer locked groove 3.1, the first struts 1.Interlocking slot 1.2 and outer locked groove 3.1 are strip shape, and interlocking slot 1.2 is arranged on the top of the first strut 1, and outer locked groove 3.1 is arranged on the top of the second strut 3, and outer locked groove 3.1 is fitted in the outside of interlocking slot 1.2, and are positioned at the top of guide groove 1.1.
Pushing block 5 is comprise the first pushing tow face 5.1 and the second pushing tow face 5.3 L shaped, is provided with the contact surface 5.2 that can contact with ratchet 2 between the first pushing tow face 5.1 and the second pushing tow face 5.3.The outer rim of ratchet 2 is provided with two groups of relative gear teeth, and every group of gear teeth comprise the draw-in groove between two teeth and two teeth, and draw-in groove is " V " type.As shown in Figure 2, one group of gear teeth on right side comprise the draw-in groove 2.3 between upper and lower two teeth 2.2 and 2.1 and two teeth, and one group of gear teeth in left side comprise the draw-in groove 2.6 between upper and lower two teeth 2.4 and 2.5 and two teeth.Between two groups of gear teeth, be upper joint face 2.7 and lower joint face 2.8.
Working process of the present invention:
Second strut 3 of this device is connected with vehicle body with the first strut 1 composition two ends of connecting rod and the back veneer of car bonnet.
As shown in Figure 3, when car bonnet is opened, relative the second strut 3 of the first strut 1 moves right, and is arranged on pushing block 5 in the first strut 1 along with the first strut 1 moves right, and the first pushing tow face 5.1 moves to ratchet 2.When the interlocking slot 1.2 of the first strut 1 and the outer locked groove of the second strut 3 3.1 occurs overlappingly, the first pushing tow face 5.1 contacts and promotes ratchet 2 left-hand revolutions with tooth 2.5.When the first pushing tow face 5.1 is fitted completely with the lower surface of ratchet 2 left side draw-in grooves 2.6, ratchet 2 stops the rotation, and forms ratchet 2 pre-determined bit, and now, staff can be felt cannot continue to open car bonnet, unclamps hand to people's signal, unclamps car bonnet.
Unclamp after car bonnet, gravity along with car bonnet self, the first strut 1 can be along with car bonnet be together because the effect of gravity is to left movement, the distance of this direction motion is very little, when the draw-in groove 2.3 on ratchet 2 right sides and the inside upper wall of the first strut 1 contact with the inwall of interlocking slot 1.2, ratchet 2 lockings, form ratchet 2 self-align, realize car bonnet and open location, as shown in Figure 4.
In the time of need to killing engine cover, car bonnet is continued to upwardly open very little angle, the lower surface that the second pushing tow face 5.3 of pushing block 5 promotes ratchet 2 left side draw-in grooves 2.6 makes ratchet 2 left-hand revolutions, when interlocking slot 1.2 and outer locked groove 3.1 form overlapping hole, the tooth 2.1 on ratchet 2 right sides is rotated in place in formed overlapping hole, now the self-align releasing of ratchet 2.
As shown in Figure 5, after self-align releasing, continue to upwardly open car bonnet, when the tooth 2.4 of ratchet 2 and the contact surface 5.2 of pushing block 5 contact, ratchet 2 stops the rotation, and realizes pre-determined bit, now, staff can be felt cannot continue to open car bonnet, unclamps hand to people's signal, unclamps car bonnet.The first strut 1 is to left movement, and the lower joint face 2.8 that the inside upper wall of the first strut 1 and interlocking slot 1.2 promote ratchet 2 makes ratchet 2 left-hand revolutions, when ratchet 2 enters the first strut 1 inside completely, realizes car bonnet and closes.
