Abstract
The utility model discloses an engine room cover lock hook structure, relates to hoods or covers of motor vehicles and is used for solving the problems that automobile engine room cover lock hooks can deform and fracture easily. The structure comprises a U-shaped hook, two mounting arms and an L-shaped reinforcing strip, wherein the U-shaped hook comprises two side wall sections, the mounting arms are connected onto the two side wall sections respectively, the two mounting arms are perpendicular to the plane where the U-shaped hook is located and extend in opposite directions, the reinforcing strip comprises a vertical reinforcing strip and a transverse reinforcing strip, the vertical reinforcing strip is fixed on one side wall section of the U-shaped hook, the mounting arm on the side wall section and the transverse reinforcing strip are collinear and extend in opposite directions. According to the structure, the reinforcing strip is arranged, so that the impact resistance of an engine room cover lock hook is greatly improved, and the service life of the engine room cover lock hook is greatly prolonged.
Description
Technical field
The utility model relates to cover or the lid of self-propelled vehicle, specifically, is a kind of cabin cover latch hook structure.
Background technology
Car engine room cover lock is also engine hood lock, and car engine room cover lock great majority are by being arranged on the cabin cover latch hook on cabin cover inner panel and being arranged on the function that the cabin cover on water tank trim is locked the realization lock that cooperatively interacts.
Automobile engine cabin cover of the prior art often needs to open and close, in closing process, between cabin cover lock and cabin cover latch hook, can produce impulsive force, after time is permanent, can cause cabin cover latch hook deformation and fracture, exist because cabin cover latch hook structure ruptures and cause automobile engine cabin cover to be opened.
In addition, the bending part of cabin cover latch hook easily produces convex moulding trace, as used vehicle under the more severe environment such as road conditions of being everlasting, can be because of small be full of cracks and the concentrated effect of moulding trace place stress of generation around of moulding trace, likely cause cabin cover latch hook bending part generation fracture by fatigue, equally, exist because cabin cover latch hook ruptures and cause automobile engine cabin cover to be opened.
After the fracture of cabin cover latch hook causes automobile engine cabin cover to be opened, the sight line that can block chaufeur the place ahead is even smashed front windshield glass, has when driving potential safety hazard.
Utility model content
The utility model object is intended to provide a kind of durable and failure-free cabin cover latch hook structure.For realizing above-mentioned technical purpose, the technical solution adopted in the utility model is as follows:
A kind of cabin cover latch hook structure, comprise U-shaped hook and two hold-down arms, described U-shaped hook comprises two side section, difference connection arm in this two side section, described two hold-down arms are perpendicular to U-shaped hook place plane and oppositely extension, and described cabin cover latch hook structure also comprises L-type strap stiffener, and this strap stiffener comprises to be strengthened vertical bar and strengthen horizontal stripe, described reinforcement vertical bar is fixed in a wherein side wall sections of U-shaped hook, the hold-down arm in this side wall sections and reinforcement horizontal stripe conllinear oppositely extension.
Adopt the utility model of technique scheme, by improving the structure of latch hook, increased strap stiffener, under the prerequisite of normal use that does not affect latch hook, the latch hook installation position that has made to increase strap stiffener is more firm, stressed more even.Even if the bending part of latch hook ruptures, also can prevent latch hook overall separation by strap stiffener, cause cabin cover to be opened.
Further limit, a wherein side wall sections of described reinforcement vertical bar and U-shaped hook is fixedly connected with by two guarantor's welderings.Two advantages of protecting weldering are open arc weldings, and its weldquality is high, and resistance to cleavage is good, and welding deformation is little, can increase the constant intensity of strap stiffener and side wall sections, raising latch hook service life.
The utility model compared to existing technology, has improved anti-impact force and the service life of latch hook itself greatly by strap stiffener is set.
Accompanying drawing explanation
Fig. 1 is the structural representation of a kind of cabin cover latch hook structure of the utility model;
Fig. 2 is cabin cover latch hook mounting structure schematic diagram;
Fig. 3 is the structural representation of a kind of cabin cover latch hook structure of the utility model.
The specific embodiment
In order to make those skilled in the art understand better the utility model, below in conjunction with drawings and Examples, technical solutions of the utility model are further illustrated.
embodiment 1:
As shown in Figure 1 and Figure 2, a kind of cabin cover latch hook structure, comprise U-shaped hook 1, two hold-down arms 2,3, U-shaped hook 1 comprises two side wall sections 11,12, connection arm 2 in side wall sections 11, connection arm 3 in side wall sections 12, and hold-down arm 2 and hold-down arm 3 are respectively perpendicular to U-shaped hook 1 place plane and oppositely extend.
Cabin cover latch hook structure also comprises L-type strap stiffener 4, and this strap stiffener 4 comprises to be strengthened vertical bar 41 and strengthens horizontal stripe 42, strengthens vertical bar 41 and is fixed in the side wall sections 11 of U-shaped hook 1, the hold-down arm 2 of correspondence and reinforcement horizontal stripe 42 conllinear oppositely extension in this side wall sections 11.
Side wall sections 11 is strengthened vertical bar 41 surely by two guarantor's solid weldings, can certainly in another side wall sections 12, by two, protect solid welding and determine connection reinforcement vertical bar 41, now, strengthen horizontal stripe 42 and hold-down arm 3 conllinear and oppositely extend, therefore the in the situation that of cabin cover latch hook full symmetric, no matter strap stiffener 4 is arranged in side wall sections 11 or side wall sections 12, and the structure of cabin cover latch hook is all identical.
Cabin cover latch hook is installed to the reserved location on cabin cover brace panel 6, and in concrete installation, the position of cabin cover latch hook band strap stiffener 4 is arranged on the near-end near Windshield.This be because cabin cover when closing or open, the stressed hold-down arm 3 that is greater than Windshield far-end of the hold-down arm 2 of Windshield near-end on cabin cover latch hook, arranges the situation that strap stiffener can prevent hold-down arm fracture in stressed large one end, improve its intensity; The conflict that can avoid on the other hand cabin cover latch hook and cabin cover lock position to install, causes its cisco unity malfunction.
embodiment 2:
As shown in Figure 3, connection arm 2 in side wall sections 11, connection arm 3 in side wall sections 12, the bearing of trend of two hold-down arms 2,3 of two hold-down arms 2,3 and embodiment 2 is contrary, when concrete installation, as long as one end that strap stiffener is set is arranged on to the proximal location of Windshield, it is the same with the stiffening effect of embodiment mono-.
Because the bending part 5 of cabin cover latch hook easily fractures, the utility model has improved anti-impact force and the service life of cabin cover latch hook greatly by strap stiffener 4 is set, and better plays the effect of protection driving safety.
A kind of cabin cover latch hook structure above the utility model being provided is described in detail.The explanation of specific embodiment is just for helping to understand method of the present utility model and core concept thereof.Should be understood that; for those skilled in the art; do not departing under the prerequisite of the utility model principle, can also carry out some improvement and modification to the utility model, these improvement and modification also fall in the protection domain of the utility model claim.
