Door lock blocks are core components of the door lock system of a vehicle. Their common faults include component wear, electronic device failure, and blocking by foreign objects. The following are common causes of failures of a door lock block:

Component wear: After long use, the mechanical components of the door lock block, such as lock tongue and lock catch, may wear and affect its normal operation.

Blocking by foreign objects: Dust and foreign objects may enter the lock block and prevent its smooth operation.

Lack of lubrication: Insufficient lubrication leads to higher frictional force of the moving parts of the lock block, and may consequently result in jamming or malfunction.

Electrical failure: Electronic control devices or circuits related to the lock block may have a problem, such as poor contact and short circuit.

Collision or deformation: The lock block my be deformed due to an external impact on the car door, and is unable to work normally.

Advantages of vika door lock block:

1. The vika door lock blocks are made of special high-strength automotive sheets, which lead to a tensile strength of 15000N, exceeding the standard requirement of 11000N and improving performance by 36%.

2. By using high-grade lubricating oil and components with better temperature resistance, vika has extended the operating temperature range of the lock blocks to -45℃~80℃, broader than the standard requirement of -40℃~75℃.

3. Waterproof micro switches from a renowned brand are adopted to solve the problem of switching signal failures caused by water and dust ingress during long-term operation.

4. High-strength and high-toughness DuPont materials are used to produce worm gears and worms, effectively solving the problem of transmission failure due to wear after long-term use.

5. Customized motors from a renowned brand are adopted and thermal protection function is added to solve the problem of motor burnout during long-term use of the products.
