Detailed description of the invention
Below in conjunction with accompanying drawing, the embodiment of the present invention is described in detail.
In describing the invention, it should be noted that, unless otherwise clearly defined and limited, term " installation ", " being connected ", " connection " should be interpreted broadly, and such as, can be fixedly connected with, also can be removably connect, or connect integratedly; Can be directly be connected, also indirectly can be connected by intermediary, can be the connection of two element internals.For the ordinary skill in the art, particular case above-mentioned term concrete meaning in the present invention can be understood.
See Fig. 1, Fig. 2 and Fig. 8, embodiments provide a kind of car bonnet lock construction, this structure comprises supporting seat 1, be fixed on the clamp 2 on supporting seat 1, the retaining pawl 3 coordinated with clamp 2, and one end is connected with retaining pawl 3, the lock pawl spring 4 that the other end is connected with supporting seat 1 and one end are connected with clamp 2, the clamp spring 10 that the other end is connected with supporting seat 1, also comprise support cover 5, support cover 5 is fixedly connected with supporting seat 1, and form enclosed box body 6 with supporting seat 1, support cover 5 is provided with car bonnet latch hook guide groove 7, guide groove 7 is for holding car bonnet latch hook 9.
In the car bonnet lock construction that the embodiment of the present invention provides, because support cover 5 is fixedly connected with supporting seat 1, and support cover 5 and supporting seat 1 form enclosed box body 6, the parts in car bonnet lock construction such as clamp spring 10 and lock pawl spring 4 is made to be accommodated in an enclosed box body 6, when in vehicle traveling process, the noise that what clamp spring 10, lock pawl spring 4 sent creak creaks can be blocked in the enclosed box body 6 that support cover 5 and supporting seat 1 formed, thus greatly reduces even thoroughly to abate the noise; And, the enclosed box body 6 that support cover 5 and supporting seat 1 are formed can clamp spring 10 or lock pawl spring 4 lost efficacy fly out from supporting seat 1 time, interception is played to clamp spring 10 or lock pawl spring 4, make the spring flown out can be closed box body 6 to be blocked in box body, thus avoid the spring flown out and hurt sb.'s feelings.
In order to improve driving engine compactedness, meet and the matching relationship of each parts in driving engine, enclosed box body 6 can take the shape of the letter U, and guide groove 7 is positioned at the U-shaped opening part of enclosed box body 6; Support cover 5 can be riveted on supporting seat 1, and riveting method is solid and reliable, makes support cover 5 be connected more firm with supporting seat 1.
In above-described embodiment, described car bonnet lock construction can also comprise elastomeric limiting stopper 8, and support cover 5 is provided with limiting stopper mounting groove 51, and limiting stopper 8 is contained in limiting stopper mounting groove 8, when car bonnet is in the closed position, limiting stopper 8 contacts with car bonnet latch hook 9.
When car bonnet is in the closed position, contact with car bonnet latch hook 9 because limiting stopper 8 is connected in limiting stopper mounting groove 51, therefore, limiting stopper 8 will play the effect stopping and limit to car bonnet latch hook 9, there is elastomeric limiting stopper 8 when being subject to the effect of car bonnet latch hook 9 power, elastic deformation can be there is, thus antagonistic force is applied to car bonnet latch hook 9, thus the kinematic velocity of car bonnet latch hook 9 is played to the effect of buffering, and then play the speed reducing car bonnet and close, the effect of the off position of limiting engine cover simultaneously.
Particularly, see Fig. 3, when car bonnet latch hook 9 contacts with limiting stopper 8, limiting stopper 8 starts to slow down car bonnet closing velocity; See Fig. 4, along with car bonnet latch hook 9 and limiting stopper 8 Exposure increase, limiting stopper 8 pairs of car bonnet closing velocities slow down more obvious; See Fig. 5, until car bonnet latch hook 9 stop motion, the clamp 2 in car bonnet lock construction is just in time by car bonnet latch hook 9 locking.
When the clamp spring 4 in car bonnet lock construction lost efficacy, clamp 2 can be opened by car bonnet drag-line (not shown), see Fig. 6, when car bonnet is closed, limiting stopper 8 is extruded by car bonnet latch hook 9 and deforms, and like this, limiting stopper 8 pairs of driving engines are covered with antagonistic force, car bonnet is upspring, and thus upspringing of limiting stopper 8 pairs of car bonnets plays certain booster action; See Fig. 7, limiting stopper 8 can open certain angle by supporting engines hood lock hook 9, makes the front end of car bonnet exceed the front bumper of vehicle, thus brings great convenience for personnel carry out operation to engine case.
In above-described embodiment, limiting stopper 8 can be arc surface with the contact surface of car bonnet latch hook 9.Arc surface friction force is little, makes limiting stopper 8 better with coordinating of car bonnet latch hook 9, thus reduces mechanical loss.
As preferably, limiting stopper 8 can be provided with spacing preiection 81, support cover 5 is provided with position-limited trough 52, position-limited trough 52 is communicated with limiting stopper mounting groove 51, and spacing preiection 81 is contained in position-limited trough 52.Spacing preiection 81 can play the effect of restriction to the position of limiting stopper 8, thus prevents limiting stopper 8 to be moved relative to the position of limiting stopper mounting groove 51.Wherein, spacing preiection 81 can be arc surface with the mating surfaces of position-limited trough 52, and arc-shaped surface friction force is less, to reduce mechanical loss.
In above-described embodiment, see Fig. 8, support cover 5 can be provided with clamp fixing rivet 53, retaining pawl fixing rivet 54 and support cover fixing rivet 55.Rivet is arranged on support cover 5 and is convenient to install, thus save the set-up time of described car bonnet lock construction.
Preferably, see Fig. 1, support cover 5 also can be provided with lining 56 under retaining pawl, can limit retaining pawl 3 lower end displacement, lining 57 on retaining pawl, can limit end movement on retaining pawl 3, thus avoids retaining pawl 3 and support cover 5 to interfere.
In above-described embodiment, support cover 5 also can be provided with clamp lower end lining 58, lining 59 on clamp 3 lower end displacement, clamp can be limited, end movement on clamp 3 can be limited, thus avoid clamp 2 and support cover 5 to interfere.
The material of the elastic spacing block in above-described embodiment is chosen as rubber, quality of rubber materials good springiness, and price is comparatively cheap.
In the description of this specification sheets, specific features, structure, material or feature can combine in an appropriate manner in any one or more embodiment or example.
The above; be only the specific embodiment of the present invention, but protection scope of the present invention is not limited thereto, is anyly familiar with those skilled in the art in the technical scope that the present invention discloses; change can be expected easily or replace, all should be encompassed within protection scope of the present invention.Therefore, protection scope of the present invention should described be as the criterion with the protection domain of claim.
