The specific embodiment
Below in conjunction with accompanying drawing, further illustrate the specific embodiment of the present utility model.
As shown in Figure 1, car side door 4 generally includes the outer panel beating 41 of car door and vehicle door side panel beating 42, and vehicle door side panel beating 42 is positioned at car side door 4 towards the orientation of doorframe.When car side door 4 is closed, vehicle door side panel beating 42 is invisible.
As Figure 2-3, existing car door door lock 1 installs by car door the inside that set bolt 11 is arranged on car side door 4, by the outer panel beating 41 of car door and vehicle door side panel beating 42, is surrounded.Car door door lock 1 is arranged on door lock installed surface panel beating 2, and the outer release link 3 of door lock for vehicles is positioned at the below of door lock installed surface panel beating 2, door lock installed surface panel beating 2 and vehicle door side panel beating 42 almost parallels.Existing door lock installed surface panel beating 2 does not block the outer release link 3 of door lock for vehicles completely, and a part for the outer release link 3 of door lock for vehicles comes out.When car side door 4 be subject to lateral impact power (this impact perpendicular to car door outside panel beating 41, namely along the direction of overall width) time, first the outer panel beating 41 of car door deforms, the outer panel beating 41 of car door after distortion pushes vehicle door side panel beating 42 again, vehicle door side panel beating 42 also deforms, and the vehicle door side panel beating 42 after distortion may be to the interior extruding of car side door 4.As shown in Fig. 6 (A), the structural representation that Fig. 6 (A) is clashed into while being existing unprotect device.Vehicle door side panel beating 42 deforms, and inwardly pushes the outer release link 3 of door lock for vehicles, plays and is similar to the effect that outer handle pulls the outer release link 3 of door lock for vehicles, makes 1 release of car door door lock, to cause car side door 4 to be opened.
As shown in Fig. 4-5, Fig. 4 is the front view of the protective device of the outer release link of door lock for vehicles in the utility model one embodiment; Fig. 5 is the lateral view of the protective device of the outer release link of door lock for vehicles in the utility model one embodiment.In the utility model; the protective device of the outer release link of protection door lock for vehicles; comprise the door lock installed surface panel beating 2 for installation car door lock 1; door lock installed surface panel beating 2 is positioned at the adjacent position of the outer release link 3 of door lock for vehicles; door lock installed surface panel beating 2 release link 3 outside door lock for vehicles is extended; form extension 21, extension 21 is for blocking the outer release link 3 of door lock for vehicles.
As shown in Fig. 6 (B), Fig. 6 (A) is the structural representation being clashed into while having protective device.Because extension 21 shelters from the outer release link 3 of door lock for vehicles, even if vehicle door side panel beating 42 release link 3 outside door lock for vehicles deforms, extension 21 stops that vehicle door side panel beating 42 is on outer release link 3 impacts of door lock for vehicles, prevent that car side door 4 from being opened by mistake, avoided in vehicular sideview collision process, the outer release link of distortion touching door lock for vehicles due to car door panel beating, the possibility that finally causes car side door to be opened, greatly reducing side hits Shi Yinmen and opens the passenger inside the vehicle that car door causes and be thrown out of or injured risk, to a certain extent, improved the security performance of automobile.
In the present embodiment, as shown in Figure 5, release link 3 bendings outside door lock for vehicles after extension 21 extends, form L shaped.Preferably, extension 21 comprises body 211 (referring to Fig. 4) and bending body 212 (referring to Fig. 5), body 211 with door lock installed surface panel beating 2 in same plane, i.e. body 211 and vehicle door side panel beating 42 almost parallels.Bending body 212 is mutually vertical with body 211, and body 211 is for blocking the outer release link 3 of door lock for vehicles completely, and bending body 212 is for surrounding the outer release link 3 of part door lock for vehicles.Bending body 212 can better protect the outer release link 3 of door lock for vehicles not to be subject to the impact of vehicle door side panel beating 42 distortion.
Preferably, the high strength steel that door lock installed surface panel beating 2 is 2.5mm-3mm by thickness is made.Because the outer panel beating 41 of car door and vehicle door side panel beating 42 are generally the regular tenacity steel plate of thickness 0.65mm-0.7mm.Therefore, the intensity of door lock installed surface panel beating 2 is greater than the intensity of vehicle door side panel beating 42, and the distortion of vehicle door side panel beating 42 can not impact door lock installed surface panel beating 2, namely can not impact extension 21.
Preferably, the intensity of door lock installed surface panel beating 2 is more than 700MPa.Here " more than 700MPa " do not refer to that the intensity of door lock installed surface panel beating 2 does not have the upper limit, and the intensity that refers to door lock installed surface panel beating 2 can adopt the maximum intensity of existing high-strength steel sheet.Because the intensity of the outer panel beating 41 of car door and vehicle door side panel beating 42 is conventionally in 300MPa left and right.Therefore, the intensity of door lock installed surface panel beating 2 is greater than the intensity of vehicle door side panel beating 42, and the distortion of vehicle door side panel beating 42 can not impact door lock installed surface panel beating 2, namely can not impact extension 21.
Than the technical scheme that increases car door panel beating intensity or thickness, the utility model only need to increase the material of door lock installed surface panel beating, and does not need the strength of materials or the thickness of the outer panel beating of whole car door and vehicle door side panel beating all to increase.Of the present utility model simple in structure, improving cost is low, and can effectively prevent that car door from being opened by mistake, in order to avoid cause the secondary injury to passenger inside the vehicle, has improved the security performance of automobile.
Above-described is only principle of the present utility model and preferred embodiment.It should be pointed out that for the person of ordinary skill of the art, on the basis of the utility model principle, can also make some other modification, also should be considered as protection domain of the present utility model.
