Description

Technical Field

[0001] This utility model relates to the field of automotive door lock manufacturing, and in particular to a plastic-coated assembly for the pin of a BJ side door lock sleeve. Background Technology

[0002] Amid the rapid development of the global automotive industry, consumers are demanding increasingly stringent requirements for overall vehicle quality. As a key component for ensuring the safety of passengers and preventing vehicle theft, the performance and reliability of car door locks directly affect the safety of the entire vehicle and the user experience. The locking mechanism in the door lock system uses a precise mechanical and electronic structure to work together, with ratchet and pawl moving to touch a micro switch to generate a signal and transmit it to the car's central control system, thereby achieving precise opening and closing of the car door and status feedback functions.

[0003] However, throughout the entire lifecycle of a vehicle, the door lock system must withstand the test of complex environments. Rain erosion, high-pressure car washes, and accidental water immersion are common technical challenges, making liquid intrusion into the door lock a significant technical problem. Taking the BJ platform door lock as an example, its current plastic coating process uses a single-stage molding method, making it difficult to form a completely sealed structure in the injection holes of the sheath pin plastic coating assembly. This process defect allows moisture to easily penetrate along the injection holes to the pin area under the influence of external liquids. Once the pin becomes damp, conductive bridging can easily occur between adjacent pins, causing series circuitry and leading to false triggering or interruption of the door lock system's signal transmission, severely affecting the normal operation of the vehicle's door control system.

[0004] Therefore, it is necessary to provide a plastic-coated assembly for the BJ side door lock sleeve pin to solve the above-mentioned technical problems. Utility Model Content

[0005] This utility model provides a plastic-coated assembly for the pin of a BJ side door lock sleeve, which solves the problem that the existing plastic-coated assembly for the pin of a BJ platform door lock sleeve is poorly sealed due to single plastic coating, and moisture can easily enter the pin part, causing signal failure of the door lock system.

[0006] To solve the above-mentioned technical problems, this utility model provides a BJ side door lock sleeve pin-coated assembly, comprising:

[0007] The device includes a pin, a first plastic coating layer, and a second plastic coating layer. The first plastic coating layer is disposed on the outer side of the pin, and the second plastic coating layer is disposed on the outer side of the first plastic coating layer.

[0008] Preferably, the second coating layer acts to fill the injection holes on the surface of the first coating layer.

[0009] Preferably, a roughening layer is provided on the outer surface of the first plastic coating layer.

[0010] Preferably, the second plastic coating layer is disposed on the outer surface of the roughened layer.

[0011] Preferably, the roughness Ra of the roughened layer is in the range of 1.6 μm to 6.3 μm.

[0012] Preferably, a waterproof filler layer is provided inside the injection hole of the first plastic coating layer.

[0013] Preferably, the waterproof filler layer is made of sealant.

[0014] Compared with related technologies, the BJ side door lock sleeve pin-coated plastic assembly provided by this utility model has the following beneficial effects:

[0015] This utility model provides a BJ side door lock sleeve pin plastic coating assembly. By setting a second plastic coating layer on the outer side of the first plastic coating layer, moisture is effectively prevented from entering the pin area, ensuring the stability of signal transmission, reducing the probability of door lock signal failure, and improving the reliability of the car door lock.

[0016] The roughening layer enhances the bonding force between the two plastic coating layers, improves the overall stability of the component, and makes the product more reliable in complex environments.

[0017] By combining a waterproof filler layer and a second plastic coating layer, the waterproof performance is further improved, providing more reliable protection for the pins, effectively reducing the possibility of signal failure due to water ingress, and improving the security and stability of the car door lock.

[0024] First Embodiment

[0025] Please refer to the following: Figure 1 , Figure 2 ,in, Figure 1 This is a schematic diagram of the structure of a first embodiment of a plastic-coated pin assembly for a BJ side door lock sleeve provided by this utility model; Figure 2 for Figure 1 The diagram shows the structure of the pin after the first plastic coating. A plastic-coated assembly for a BJ side door lock sleeve pin includes: a pin 1, a first plastic coating layer 2, and a second plastic coating layer 3. The first plastic coating layer 2 is disposed on the outer side of the pin 1, and the second plastic coating layer 3 is disposed on the outer side of the first plastic coating layer 2.

[0026] The second plastic coating layer 3 is used to fill the injection holes on the surface of the first plastic coating layer 2.

[0027] The working principle of the BJ side door lock sleeve pin plastic-coated assembly provided by this utility model is as follows:

[0028] During the operation of the car door lock, pin 1 is used to transmit signals. The first plastic coating layer 2 and the second plastic coating layer 3 work together to protect pin 1. When encountering rain or other moisture, the second plastic coating layer 3 prevents moisture from entering the area of ​​pin 1 through the injection holes on the surface of the first plastic coating layer 2, ensuring that pin 1 works normally, transmits signals stably, and avoids signal failure due to water ingress.
