FIELD OF INVENTION
This invention relates to an improved brace hood lock.
PRIOR ART
Presently, a number of solutions are available to minimize the high stress
observed in latch mounting area of brace hood lock (during the hood
closing).
The possible solutions to the above said problem are listed herein below:
1. Increase in the tensile strength of the brace hood lock
2. Increase in the thickness of the brace hood lock
3. Addition of reinforcement to the brace hood lock
4. Change in the shape of the mating part (hood latch)
5. Change in the shape of the brace hood lock to reduce stress.
However, the first three solutions will increase the overall cost and fourth solution is not feasible, as mating part cannot be modified always during the design and development of vehicle system, due to following reasons:
• It is difficult to modify the latch as generally used across many other models
• During later stages of design and development, it is generally very difficult and time consuming to radically modify complete system.
Therefore, the only solution feasible at any and all stages of design and development is to modify the brace in such a way that, the mating part won't change.

OBJECTS OF THE INVENTION
The primary object of the present invention is to provide an improved brace hood lock which overcomes disadvantage associated with the prior art.
Another object of the present invention is to provide an improved brace hood lock which is simple in construction.
Still another object of the present invention is to provide an improved brace hood lock which is effective and efficient.
Still another object of the present invention is to increase the strength of the brace hood lock in the latch mounting area without changing the other mating parts
STATEMENT OF INVENTION
According to this invention there is provided an improved brace hood lock comprising of a bead of shape for example circular on a panel around weld nut to reduce stress.
BRIEF DESCRIPTION OF THE ACCOMPANYING DRAWINGS
Further objects and advantages of this invention will be more apparent from the ensuing description when read in conjunction with the accompanying drawings and wherein:
Fig. 1 and 2 shows the present invention.
Fig.3 and 4 shows the test results.

DETAILED DESCRIPTION OF THE INVENTION WITH REFERENCE TO THE ACCOMPANYING DRAWINGS;
Reference may be made to the accompanying drawings wherein improved brace hood lock comprising of a bead of shape for example circular on a panel around weld nut to reduce stress.
The above provision improves stiffness of panel in mating area without change in the other mating part.
The present invention helps in providing the localized stiffness in weak part without modifying the other mating part. Hence, it will result in saving of time. Further, it eliminates the usage of higher thickness material or high strength material, which in turn will lead to low cost and light weight of vehicles.
In addition, the present invention results in elimination of the additional reinforcement, which in turn will lead to light weight and low cost of vehicle.
Circular Bead is adopted to provide the uniform stress distribution around the weld nut. Though, it is possible to adopt different shape of bead based on the stress requirement, but the benefit of uniform stress distribution is not there in other shape. For example in case of square shape of bead, there will be high stress at corner area, which may lead to failure.

The circular bead added in brace hood lock satisfies the stress requirement of hood slam test.
It is to be noted that the formulation of the present invention is susceptible to modifications, adaptations and changes by those skilled in the art. Such variant formulations are intended to be within the scope of the present invention which is further set forth under the following claims:-

WE CLAIM:
1. An improved brace hood lock comprising of a bead of shape for example circular on a panel around weld nut to reduce stress.
2. An improved brace hood lock as claimed in claim 1 provides uniform stress distribution around the weld nut.
3. An improved brace hood lock as claimed in claim 1 or 2 improves stiffness of panel in mating area without change in the other mating part.
4. An improved brace hood lock substantially as herein described with reference to the accompanying drawings.
