Abstract

The utility model belongs to the technique of car door locks for automobiles, which particularly relates to a welding assembly structure for a reinforcing element of a car door (front doors and rear doors) lock pin of which the strength can be ensured. In the structure, the moulding surface of the installing connection part of the reinforcing element of the lock pin and a side wall outer skin is designed to be consistent with the partial moulding surface of the side wall outer skin. Moulding surface positioning is adopted, and at the same time, a positioning hole is respectively and corresponding designed on the reinforcing element of the lock pin and the side wall outer skin. Because the reinforcing element of the car door lock pin of the utility model adopts the moulding surface positioning mode, only one positioning hole needs to be designed on the reinforcing element of the lock pin and then the positional accuracy of the lock pin hole can be satisfied. Another positioning hole needs not to be designed near the lock pin hole, and in this way, on one hand, the connection strength between the reinforcing element of the lock pin and the side wall welding position can be ensured, correspondingly the strength of the partial contact position of the lock pin and the side wall is increased, and on the other hand, the positioning fixture and the working procedure are reduced, which saves the cost.

Description

Arrangements for automotive doors lock pin reinforcement welding assembly structure

Technical field

The utility model belongs to the arrangements for automotive doors lock technology, is specifically related to a kind of in order to guarantee the lock pin reinforcement welding assembly structure of car door (forward and backward door) lock pin intensity.

Background technology

No matter whether the forward and backward door of car pass through long-term folding, and its lock pin all should be in normal stabilized conditions, and this just needs lock pin reinforcement keeping enough intensity with gusset exterior skin weld.

The lock pin reinforcement of present domestic car is when welding with the gusset exterior skin, having designed two locating dowel pin anchor clamps holes at the exterior skin place locatees jointly, this has had a strong impact on the intensity of lock pin and the local contact site of gusset, solder joint is come off easily opening, lock pin reinforcement is installed not firm, thereby influences the normal operation of lock pin.Simultaneously, adopt two locating dowel pin anchor clamps holes to locate jointly, need anchor clamps, and must carry out corresponding working procedures again, certainly will will pay corresponding productive costs.

Summary of the invention

The purpose of this utility model is the problem at the prior art existence, and a kind of arrangements for automotive doors lock pin reinforcement welding assembly structure is provided, and solves the problem of the local contact site of lock pin and gusset intensity difference, reduces anchor clamps and operation, guarantees forward and backward door lock pin intensity.

The technical solution of the utility model is to be designed to the profile that lock pin reinforcement and gusset exterior skin are installed connecting bridge with the gusset exterior skin should part cambered surface profile consistent, adopted the profile location, knock hole of corresponding respectively design gets final product on lock pin reinforcement and gusset exterior skin simultaneously.

The utility model is because the latch for vehicle door reinforcement has adopted the profile locate mode, only need on lock pin reinforcement, to design the positional precision that a knock hole just can satisfy lockpin hole, and do not need near lockpin hole, to design again a knock hole, guarantee the Joint strenght of lock pin reinforcement and gusset weld so on the one hand, the corresponding intensity that has increased lock pin and the local contact site of gusset, reduce positioning fixture and operation on the other hand again, saved cost.

Description of drawings

Fig. 1 is a kind of structural representation of front door of automobile lock pin reinforcement welding assembly;

Fig. 2 is the scheme drawing of driver door lock pin reinforcement and gusset exterior skin profile location;

Fig. 3 is a kind of structural representation of automobile tail gate lock pin reinforcement welding assembly.

Among the figure: 1, Qianmen door lock limiting device 2, Qianmen lock pin reinforcement 3 back door door lock limiting devices 4, back door lock pin reinforcement 5,6 knock holees 7 are that gusset exterior skin A, B are location, two places profiles

The specific embodiment

As shown in Figure 1, Qianmen lock pin reinforcement welding assembly is by Qianmen door lock limiting device 1, Qianmen lock pin reinforcement 2 is formed, Qianmen door lock limiting device 1 is located at the inside of Qianmen lock pin reinforcement 2, referring to Fig. 2, Qianmen lock pin reinforcement 2 is designed to this part cambered surface profile of gusset exterior skin 8 consistent with the profile that gusset exterior skin 7 is installed connecting bridge, as the A among Fig. 2, B two places, when welding, take the profile location (to rely on A, location, B two places) mode, so just only needing to design an anchor clamps knock hole 5 on Qianmen lock pin reinforcement 2 locatees, and need not on the gusset exterior skin two knock holees of design, reduced operation, save cost, guaranteed the intensity of the gusset part that contacts with lock pin.

As shown in Figure 3, lock pin reinforcement welding assembly in back door is also the same with Qianmen lock pin reinforcement welding assembly, form by back door door lock limiting device 3, back door lock pin reinforcement 4, the profile that back door lock pin reinforcement 4 and gusset exterior skin are installed connecting bridge is also should part cambered surface profile consistent with the gusset exterior skin, and knock hole 6 of design can satisfy positioning requirements on back door lock pin reinforcement 4.

Claims

1, arrangements for automotive doors lock pin reinforcement welding assembly structure, form by lock pin reinforcement and its inner door lock limiting device that is provided with, it is characterized in that: the profile that lock pin reinforcement and gusset exterior skin are installed connecting bridge and gusset exterior skin are should part cambered surface profile consistent, correspondingly respectively on lock pin reinforcement and gusset exterior skin design a knock hole.
