Description

Technical Field

[0001] The invention relates to a locking device, and in particular to a cable outlet structure and an assembly method on a novel locking device. Background Art

[0002] At present, in new energy vehicles and other electronic locking devices that require high sealing, the cable connection and outlet usually adopts a built-in connector structure, and waterproof treatment is performed by inserting special rubber parts on the cables. However, this traditional waterproof design has many defects. First, the assembly process of the cable passing through the rubber parts is cumbersome and the assembly efficiency is low, especially when mass production is required, the complexity of the assembly process increases significantly.

[0003] Secondly, as the use time increases, the pulling of the cable may cause the rubber parts to deform or age, thereby reducing the waterproof performance and causing the product to fail the airtightness test, thus affecting its long-term reliability. In addition, the built-in connector waterproof design in the prior art also requires the development of dedicated rubber parts, which not only increases the production cost, but also limits the versatility of the device and the flexibility of design.

[0004] Therefore, there is an urgent need for a more efficient, reliable cable outlet method with better waterproof sealing effect to solve the problems in the prior art. Summary of the invention

[0005] In order to solve the above problems, the present invention provides a cable outlet structure and assembly method on a new locking device. By placing the connector module externally and adopting an integrated modular design, the assembly process is made simpler and more efficient, and the tedious steps of threading the cable to the rubber part are reduced, thereby significantly improving the assembly efficiency and effectively solving the deficiencies in the prior art.

[0006] The present invention is realized by the following technical scheme: a cable outlet structure on a novel locking device, comprising: A PCBA board with an external connector mounted thereon; A housing, used to accommodate the PCBA board; A leak-proof foam, arranged between the connector on the PCBA board and the bottom shell; A connector wire, which passes through the upper cover and is connected to the connector on the PCBA board; The potting glue sealing area is used to potting the area where the connector wire passes through.

[0007] As a preferred technical solution, the housing includes: A bottom shell, used for accommodating the PCBA board; An upper cover is assembled with the bottom shell to close the PCBA board.

[0008] As a preferred technical solution, the leak-proof rubber foam is made of a material with high weather resistance.

[0009] As a preferred technical solution, the upper cover and the bottom shell are assembled by a snap-fit ​​structure or screws.

[0010] A method for assembling a locking device cable outlet of the present invention comprises the following steps: Step 1: Provide a PCBA board with a connector installed on it; Step 2: Assemble the leak-proof foam to the connector on the PCBA board; Step 3: Assemble the PCBA board into the bottom shell so that the leak-proof foam is in close contact with the bottom shell; Step 4: Assemble the upper cover and the bottom shell together to enclose the PCBA board; Step 5: Pass the connector wire through the upper cover and connect it to the connector on the PCBA board to complete the circuit connection; Step 6: Apply sealing glue to the area where the connector wire passes through to ensure the sealing performance of the area to achieve a waterproof effect; Step 7: Test the sealing performance of the device after glue filling to ensure that it meets the airtightness requirements.

[0011] As a preferred technical solution, the leak-proof foam is pre-compressed before being assembled to the PCBA board to ensure its sealing effect.

[0012] The beneficial effects of the present invention are as follows: the present invention makes the assembly process simpler and more efficient by placing the connector module externally and adopting an integrated modular design, thereby reducing the tedious steps of threading the cable to the rubber parts, thereby significantly improving the assembly efficiency. Secondly, the provision of leak-proof rubber foam can effectively alleviate the problem of rubber part deformation caused by cable pulling, ensuring the waterproof and sealing performance during long-term use. At the same time, the use of potting glue for sealing enhances the air tightness and protection capability of the entire device, and is particularly suitable for application scenarios such as new energy vehicle electronic locks that require high-strength sealing. In addition, the present invention reduces the error of human operation, improves the consistency and quality stability of the product, and reduces the production cost through the design of an automated assembly process, and has broad market application prospects.

[0015] All features disclosed in this specification, or steps in all methods or processes disclosed, except mutually exclusive features and / or steps, can be combined in any manner.

[0016] Any feature disclosed in this specification (including any additional claims, abstract and drawings), unless otherwise stated, may be replaced by other equivalent or alternative features with similar purposes. That is, unless otherwise stated, each feature is only an example of a series of equivalent or similar features.

[0017] like Figure 1 and Figure 2 As shown, the present invention provides a novel cable outlet structure of a locking device, the design of which significantly improves the assembly efficiency and ensures the sealing performance of the device through an external connector and an integrated modular assembly method; The PCBA board 2 in the cable outlet structure is installed with an external connector. Compared with the traditional built-in design, the external connector can reduce the internal space occupied and make assembly and maintenance more convenient, while also improving the compactness of the overall structure.

[0018] The housing part is composed of a bottom shell 5 and an upper cover 1. The bottom shell 5 is used to accommodate the PCBA board 2. The upper cover 1 and the bottom shell 5 cooperate to enclose the PCBA board 2, and the two are fixed by a snap-fit ​​structure or screw assembly. It can provide flexible assembly options. The snap-fit ​​structure simplifies the assembly process, and the screw assembly improves the firmness and stability of the structure, which is suitable for different application scenarios.

[0019] The leak-proof rubber foam 3 is placed between the connector and the bottom shell 5 to ensure the sealing effect. The foam is made of highly weather-resistant materials and can maintain good waterproof and airtight performance in long-term use to avoid sealing failure caused by cable pulling or changes in the external environment. During the assembly process, the leak-proof rubber foam 3 can also be pre-compressed to further enhance its close fit with the shell and ensure the sealing effect.

[0020] The connector cable 4 passes through the upper cover 1 and is connected to the connector on the PCBA board 2. This design greatly simplifies the cable assembly method and reduces the risk of cable failure due to bending or pulling. To further improve the sealing, the area where the connector cable 4 passes through will be sealed with potting glue. Silicone or epoxy resin materials are preferably used. The potting glue is not only waterproof, but also effectively resists external corrosion and vibration, ensuring the service life of the electronic lock in harsh environments.

[0021] After assembly is completed, the sealing performance of the glue-filled sealing area is tested to ensure that it meets the airtightness standard. The test can be performed using airtightness testing equipment to verify whether the device's waterproof and sealing performance meets the requirements. In addition, the durability and reliability of the product can be further ensured by underwater immersion or high-pressure environmental testing.

[0022] The beneficial effect of the present invention is that the present invention makes the assembly process simpler and more efficient by placing the connector module externally and adopting an integrated modular design, reduces the tedious steps of threading the cable to the rubber part, and thus significantly improves the assembly efficiency.

[0023] Secondly, the provision of the leak-proof rubber foam 3 can effectively alleviate the problem of rubber component deformation caused by cable pulling, thereby ensuring waterproof and sealing performance during long-term use.

[0024] At the same time, the use of potting glue for sealing enhances the airtightness and protection capabilities of the entire device, which is especially suitable for application scenarios such as new energy vehicle electronic locks that require high-strength sealing.

[0025] In addition, the present invention reduces errors caused by human operation, improves product consistency and quality stability, and reduces production costs through the design of an automated assembly process, and has broad market application prospects.

[0026] The above is only a specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any changes or substitutions that are not conceived through creative work should be included in the protection scope of the present invention. Therefore, the protection scope of the present invention should be based on the protection scope defined in the claims.
