Definitions
- the present invention relates to a structure for locking a hood of a vehicle, and more particularly a structure for mounting a striker of a hood.
- the hood (also called engine hood) of a vehicle can isolate the noise generated by an engine during operation, while maintaining the cleanliness of the engine compartment.
- the locking structure of a hood is intended to control the opening and closing of the hood, and comprises a striker (or in English "strike”) placed on the hood and a bolt (or in English "latch”) ) arranged on the bodywork, the connection points between the striker and the hood being rigid connections, consideration must be given to avoiding the collision of a pedestrian's head with the connection points of the striker during a frontal impact of the vehicle.
- the outer plate of the hood deforms towards the inner plate of the hood during a frontal impact, in order to absorb impact forces exerted on the hood by the pedestrian's head and thus constitute a buffer for the pedestrian's head, which implies that the inner plate of the hood has a certain stamping depth.
- the depth of stamping expected to ensure the protection of the pedestrian that the interior plate of the cover is insufficiently strong (or even easy to be broken) after its forming, which is detrimental to the lifespan of the hood.
- the invention aims to overcome the drawbacks of the aforementioned state of the art, by proposing a structure for mounting a cover striker, which ensures the protection of the head of a pedestrian while producing a cover with improved stamping capability.
- the invention proposes a structure for mounting a striker of a hood, said striker comprising an engagement part and first and second legs supporting said engagement part, said engagement part being able to engaging with or disengaging from a bolt disposed on the bodywork, said first and second legs respectively defining first and second attachment ends for attaching said striker to the interior side of the hood, wherein, said first and second ends of clip are respectively arranged one behind the other spaced apart in the longitudinal direction of the cover, and said first clip end is closer to the outer side of the cover than said second clip end.
- the invention may further comprise one or more of the characteristics as described below, which can be combined with each other.
- said hood comprises an interior plate of the hood and an exterior plate of the hood, said first and second attachment ends of said striker being attached to said interior plate of the hood by means of a plate mounting plate, said mounting plate being disposed between said outer cover plate and said inner cover plate.
- the interior plate of the hood has a reduced drawing depth in front of said first attachment end than behind said second attachment end.
- said mounting plate in the longitudinal direction of the cover, has, from the front towards the rear, a front part, a central part and a rear part, said central part having a first mounting surface connected to said first attachment end and a second mounting surface connected to said second attachment end, said first mounting surface and said second mounting surface being arranged in a stepped manner, said first mounting surface being closer to said outer cover plate than said second mounting surface.
- said first mounting surface and said second mounting surface are arranged parallel to each other in a manner presenting a difference in height, the engagement part being arranged parallel to said first mounting surface or to said second mounting surface.
- said mounting plate is provided with lugs at its front part, said mounting plate being able to be welded to said inner plate of the cover by the lugs.
- support members extend from the two lateral sides of said central part and from said rear part of said mounting plate towards said outer plate of the cover, the support members being intended to create a cushioning space between said outer cover plate and said inner cover plate.
- the distance between said first attachment end and said second attachment end is greater than or equal to the longitudinal length of said engagement part.
- said first leg is provided with a first elbow
- said second leg is provided with a second elbow, said first elbow and said second elbow being bent towards the front and the bottom of the hood.
- said first attachment end is closer to the axis of the bolt than said second attachment end.
- the mounting structure of the invention particularly concerns a cover striker. Thanks to the structural arrangement of the connection points between the striker and the cover, it is ensured that the impact zone of a pedestrian's head does not come into contact with the rigid connection points during an impact with the pedestrian, which guarantees the safety of the pedestrian. At the same time, the structural arrangement of the connection points reduces the thickness of the front end of the hood, increases the possibility of drawing the hood in this area, and ensures good strength of the hood in this area.
- FIG. 1 shows schematically, in a sectional view, the mounting structure of a cover striker according to one embodiment of the invention
- FIG. 2 shows schematically, in a sectional view, the connection area between the striker and the mounting plate
- FIG. 3a shows schematically, in a perspective view, the connection zone between the striker and the mounting plate at a viewing angle
- FIG. 3b shows schematically, in a perspective view, the connection zone between the striker and the mounting plate from another viewing angle
- FIG. 4 shows a schematic view of the section corresponding to the section in Figure 1;
- FIG. 5 shows a schematic view of the section of the engagement zone between the striker and the bolt
- FIG. 6 shows a schematic view of the section corresponding to the section of Figure 1, in which the suspension part is shown in dotted lines.
- FIG. 7 illustrates a schematic view of the impact zone of a pedestrian's head against the hood.
- FIG. 8 shows a schematic view of the interior of the hood, in which part of the hood has been omitted to reveal the interior of the hood.
- orientation or position relations are orientation relations or position shown in the accompanying drawings, solely for convenience of description, and do not indicate or imply that the device or element in question must have any particular orientation, or be constructed and function in any particular manner. They should not be understood as a limitation of the invention.
- first and second are used for descriptive purposes only and should not be understood to indicate or imply relative importance.
- the longitudinal direction of the hood is substantially the front-to-rear direction of the length of the hood, in which the front end of the hood is a free end, and the end rear of the hood is an end hinged to the bodywork. It should be noted that the longitudinal direction of the hood extends along the surface of the hood; and the transverse direction of the hood is substantially the left-right direction of the width of the hood.
- a striker 12 is arranged on the inner side of the cover 10 when closing the cover 10, the striker 12 is engaged with a bolt 20 (illustrated in Figure 5), which thus locks the cover 10 on the bodywork.
- Figure 5 illustrates an axis 202 of the bolt 20 on which the striker 12 is engaged with the bolt 20. It should be understood that the vibratory excitation of the road is transmitted from the bolt 20 to the striker 12 along this axis 202 during the rolling of the vehicle.
- the striker 12 comprises an engagement part 120 and first 121 and second 122 legs supporting the engagement part 120, in which the engagement part 120 is located at the bottom of the striker 12 and is able to engage with (as illustrated in Figure 5) or disengage from a bolt 20 placed on the bodywork.
- connection points between the striker 12 and the cover 10 are rigid connections, the first 121 and second 122 legs respectively define first 1211 and second 1221 attachment ends for attaching the striker 12 to the interior side of the cover 10, the first 1211 and second 1221 attachment ends being respectively located at the top of the first 121 and second 122 legs, and the engagement part 120 connecting the bottom of the first leg 121 and the bottom of the second leg 122, so that the striker 12 is substantially configured so as to have a U-shaped cross section.
- the first 1211 and second 1221 attachment ends are linked to the interior side of the cover 10 by riveting.
- the first 1211 and second 1221 attachment ends are respectively arranged one behind the other spaced in the longitudinal direction of the cover 10, otherwise said, the first attachment end 1211 is closer to the front end of the cover 10. More particularly, the first attachment end 1211 is closer to the exterior side of the cover 10 than the second attachment end 1221, sort that the front end of the hood 10 close to the bumper (not shown) of the vehicle has a reduced thickness, in which the exterior side of the hood 10 is opposite the interior side of the hood where the striker 12 is arranged, the exterior side of the cover 10 forming the exterior side of the bodywork.
- the cover 10 comprises an inner plate of the cover 101 and an outer plate of the cover 102, in which the inner plate of the cover 101 and the outer plate of the cover 102 are connected by a structure with dropped edges so that the cover 10 is shaped like a hollow structure, which contributes to the protection of a pedestrian.
- the striker 12 is directly attached to the inner cover plate 101, or alternatively, the striker 12 is attached to the inner cover plate 101 by means of an additional mounting plate.
- the first 1211 and second 1221 attachment ends of the striker 12 are attached to the interior plate of the cover 101 by means of a mounting plate 30, the mounting plate being arranged between the outer plate of the cover 102 and the inner plate of the cover 101.
- the mounting plate 30 is fixed to the inner plate of the cover 101.
- the interior plate of the cover 101 has a reduced drawing depth in front of the first attachment end 1211 than behind the second attachment end 1221, particularly with reference to Figure 4, the interior plate of the cover 101 has a drawing depth h1 in front of the first attachment end 1211 and a drawing depth h2 behind the second attachment end 1221. Thanks to the structural arrangement of the first 1211 and second 1221 attachment ends, the drawing depth h1 is less than the drawing depth h2, the drawing depth being formed in order to create a space for protection of a pedestrian between the inner plate of the hood 101 and the outer plate of the hood 102.
- the inner plate of the hood 101 has a stamping slope from the location where the inner plate of the hood has the depth stamping h1 towards the location where the inner plate of the cover is engaged with the most front part of the outer plate of the cover 102.
- the stamping slope of the inner plate of the hood must be arranged at an appropriate value to ensure the resistance of the inner plate of the hood having this same depth of drawing, it follows that the cover 10 must be provided with an elongated suspension part 100 to achieve the aforementioned drawing slope, the suspension part 100 leading to an additional suspension length Lx of the cover 10.
- the inner plate of the cover 101 has a reduced stamping depth in front of the first attachment end 1211, the stamping slope being formed without the provision of the aforementioned suspension part 100; and the inner plate of the cover 101 thus formed still has sufficient strength after its forming by stamping. Furthermore, this mounting structure makes it possible to offer a cover having a significantly distinctive appearance compared to existing models, and makes it possible to reduce the weight of the cover as well as its manufacturing cost.
- the longitudinal direction of the mounting plate 30 attached to the inner plate of the cover 101 is parallel to the longitudinal direction of the cover 10, and in the longitudinal direction of the cover 10, the plate of mounting 30 has, from front to rear, a front part 301, a central part 302 and a rear part 303, in which the central part 302 has a first mounting surface 3021 connected to the first attachment end 1211 and a second mounting surface 3022 connected to the second attachment end 1221.
- the first 3021 and second 3022 mounting surfaces are arranged in a stepped manner.
- the first mounting surface 3021 is closer to the outer cover plate 102 than the second surface of the cover. mounting 3022, so that the first attachment end 1211 is closer to the exterior side of the cover 10 than the second attachment end 1221.
- first 121 and second 122 legs of the striker 12 adjacent to the first 1211 and second 1221 corresponding attachment ends are respectively arranged perpendicular to the first 3021 and second
- the respective parts of the first 121 and second 122 legs adjacent to the first 1211 and second 1221 corresponding attachment ends extend respectively from the first 3021 and second 3022 mounting surfaces in a direction parallel to the axis 202 of the bolt 20. It should be understood that at locations adjacent to the first 3021 and second 3022 mounting surfaces of the mounting plate 30, the direction longitudinal of the cover 10 extends in the front-rear direction in a plane parallel to the first 3021 and second 3022 mounting surfaces.
- the outer plate of the cover 102 is omitted to reveal a mounting plate 30 mounted on the inner plate of the cover 101, the front part 301 of the mounting plate 30 being provided with tabs 3011, the mounting plate 30 being able to be welded to the interior plate of the cover 101 by the tabs 3011.
- the tabs 3011 are preferably arranged on the two lateral sides of the front part 301, and the operator can choose to further weld the mounting plate 30 to the interior plate of the cover 101 at the level of the tabs 3011, in In other words, the tabs 3011 provide pre-weld points and, where appropriate, reinforce the connection between the front end of the mounting plate 30 and the inner cover plate 101 to provide a more stable structure and therefore better transmission of forces.
- support members extend from the two lateral sides of the central part 302 and from the rear part 303 of the mounting plate 30 towards the outer plate of the cover 102, the support members being for example a rear support member 3030 and two central support members 3020 arranged symmetrically, the support members being intended to create a damping space between the outer plate of the cover 102 and the inner plate of the cover 101, that is to say during an impact, the mounting plate 30 absorbs impact forces by the deformation of its support members.
- the longitudinal direction of the cover 10 extends in the front-to-back direction in a plane parallel to the first 3021 and second 3022 mounting surfaces of the mounting plate 30.
- the distance L2 between the first 1211 and second 1221 attachment ends is greater than or equal to the longitudinal length L1 of the engagement part 120, so that during transmission of the vibratory excitation coming from the road between the bolt 20 and the mounting plate 30, the striker 12 better disperses the vibratory excitation to the plate mounting 30 and thus avoids the concentration of the vibratory excitation.
- the first leg 121 of the keeper 12 is provided with a first elbow 1212
- the second leg 122 is provided with a second elbow 1222, the first elbow 1212 and the second elbow 1222 being bent towards the front and the bottom of the cover 10 to respectively provide bending resistance to the first 121 and second 122 legs.
- the first attachment end 1211 is closer to the axis 202 of the bolt 20 than the second attachment end 1221 when the engagement part 120 of the striker 12 is engaged with the bolt 20.
- the first attachment end 121 1 is subjected to a greater vibration load than the second attachment end 1221 because the first attachment end 1211 is closer to the axis 202 of the bolt 20, so that the front part 301 of the mounting plate 30 close to the first attachment end 1211 exerts a greater load on the plate interior of the cover 101.
- the operator can choose to weld the tabs 3011 arranged on the front part of the mounting plate. mounting 30 to the interior plate of the hood 101 to disperse the continuous vibratory excitation of the road throughout the hood 10.
- the invention improves on the one hand the possibility of stamping the cover and in particular the inner plate of the cover, and on the other hand the lifespan of the cover and its waste. It should be noted that the protection of a pedestrian is ensured by the structural arrangement of the strike itself and by the arrangement of the connection points between the strike and the cover.
