Abstract
The utility model discloses a type engine hinge of cranking arm, crank arm and fixing support including mutual articulated, fixing support is last to be equipped with first dog, crank arm including connecting portion, buffering portion and hinged end, the hinged end is U type groove structure, fixing support is located in the middle of this U type groove, the bottom in U type groove is equipped with the second dog, buffering portion is one section spiral helicine arc structure, and this tangential contained angle in arc both ends is 21~23, connecting portion all are equipped with in the both sides of connecting portion and turn over the hem for straight platelike structure. The utility model has the advantages of stability is good, the security performance is high.
Description
Technical field
The utility model relates to a kind of hinge, is specifically related to a kind of crank arm type motor hinge.
Background technology
Engine front cover hinge of the prior art, the junction of its hinged seat and swing arm is the slabbed construction of individual layer, and passes through pinned connection.If publication number is the utility model of CN2888027, if its swing arm is subject to the power of side direction, its junction is then easily damaged; And braced structures and less stable.Simultaneously because its shroud upper panel and swing arm are for being rigidly connected, and swing arm close after position do not limit, so when shroud upper panel is subject to the impact force of forward, swing arm is easy to deform and even ruptures, and then shroud upper panel and windshield are bumped against; When shroud upper panel is subject to power straight down and deformation occurs, shroud upper panel can move down and extrude miscellaneous part, cannot play a protective role, and can not meet the demand for security of automobile.
Utility model content
For the defect that above-mentioned prior art exists, technical problem to be solved in the utility model is to provide a kind of good stability, crank arm type motor hinge that security performance is high.
In order to solve the problems of the technologies described above, the utility model provides a kind of crank arm type motor hinge, comprise cranking arm and fixed bearing of being hinged, described fixed bearing is provided with the first block, described cranking arm comprises connecting portion, buffer part and hinged end, described hinged end is U-type groove structure, and described fixed bearing is positioned in the middle of this U-type groove, and the bottom of described U-type groove is provided with the second block; Described buffer part is one section of spiral helicine arcuate structure, and the angle of the arc two ends tangent line of this buffer part is 21 ° ~ 23 °; Described connecting portion is straight platy structure, is equipped with flanging in the both sides of connecting portion.
Further improvement as the utility model above-mentioned crank arm type motor hinge: the angle of the arc two ends tangent line of described buffer part is 22 °; It is highly the flanging of 3cm that described buffer part both sides are integrally formed with.
Further improvement as the utility model above-mentioned crank arm type motor hinge: described buffer part also punching press has reinforcing rib.
Adopt the crank arm type motor hinge of said structure to have the following advantages: because hinged end is U-type groove structure, fixed bearing is positioned in the middle of this U-type groove, supporting & stablizing, to be not easily damaged.Bottom due to U-type groove is provided with the second block, can limit swing arm close after position, prevent shroud upper panel be subject to larger external force deformation and move down.Because buffer part is one section of spiral helicine arcuate structure, when shroud upper panel is subject to the impact force of forward, can there is larger elastic deformation and absorb kinetic energy in this buffer part, and prevent fracture of cranking arm, safety is protected.
Accompanying drawing explanation
Fig. 1 is the structure chart of the utility model crank arm type motor hinge embodiment;
Fig. 2 is the schematic diagram of the utility model crank arm type motor hinge embodiment.
In figure, 1 for cranking arm, and 2 is fixed bearing, and 3 is connecting portion, and 4 is buffer part, and 5 is hinged end, and 6 is the first block, and 7 is the second block, and 8 is flanging, and 9 is reinforcing rib.
Detailed description of the invention
As shown in Figure 1, 2, crank arm type motor hinge comprises 1 and the fixed bearing 2 of cranking arm be hinged.Near being integrally formed with the first block 6 with 1 junction of cranking arm on fixed bearing 2.Above-mentioned cranking arm 1 comprises connecting portion 3, buffer part 4 and hinged end 5.Hinged end 5 is U-type groove structure, and fixed bearing 2 is positioned in the middle of this U-type groove, connecting pin successively through the left side wall of U-type groove, fixed bearing 2, U-type groove right side wall and rivet.The bottom of U-type groove is provided with and can limits the second block 7 that swing arm closes rear position, even if cover plate is subject to power straight down and deformation occurs, due to the effect of the second block 7, shroud upper panel can not move down and extrude miscellaneous part.Buffer part 4 is one section of spiral helicine arcuate structure, and the angle of this arc two ends tangent line is 22 °, and the kinetic energy that now this buffer part 4 absorbs is maximum value.When shroud upper panel is subject to the impact force of forward, can there is larger elastic deformation and absorb kinetic energy in this buffer part 4, prevent 1 fracture of cranking arm, substantially increase safety as spring.In order to ensure its intensity, it is highly the flanging 8 of 3cm that buffer part 4 both sides are integrally formed with, and buffer part 4 also punching press has reinforcing rib 9.Connecting portion 3 is straight platy structure, is equipped with flanging 8 in the both sides of connecting portion 3.
Above the technical scheme that the utility model embodiment provides is described in detail, apply specific case herein to set forth the principle of the utility model embodiment and embodiment, the explanation of above embodiment is only applicable to the principle helping to understand the utility model embodiment; Meanwhile, for one of ordinary skill in the art, according to the utility model embodiment, detailed description of the invention and range of application all will change, and in sum, this description should not be construed as restriction of the present utility model.
