[0002] At present, in new energy vehicles and other electronic locking devices that require high sealing performance, the connection and outlet mode of the cable usually adopts an embedded connector structure, and a special rubber part is sleeved on the cable for waterproof treatment. However, this traditional waterproof design has many defects. First of all, the assembly process of the cable passing through the rubber part is relatively cumbersome, and the assembly efficiency is low, especially in the case of mass production, the complexity of the assembly process increases significantly.

[0003] Secondly, with the extension of use time, the pulling of the cable may cause the deformation or aging of the rubber part, thereby reducing the waterproof performance, causing the product to fail to pass the air tightness test, and affecting the reliability of long-term use. In addition, the embedded connector waterproof design in the prior art also needs to develop a special rubber part, which not only increases the production cost, but also limits the universality and design flexibility of the device.

[0004] Therefore, there is an urgent need for a more efficient, reliable and better waterproof sealing effect cable outlet mode to solve the problems in the prior art. SUMMARY

[0005] In order to solve the above problems, the present application provides a new cable outlet structure on a locking device and an assembly method, which externally places the connector module and adopts an integrated modular design, so that the assembly process is more simple and efficient, and the cumbersome 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.

[0016] As a preferred technical solution, the upper cover and the bottom shell are assembled through a buckle structure or screw assembly.

[0017] The assembly method of the locking device cable outlet of the application comprises the following steps:

[0018] Step one, providing a PCBA board with a connector mounted thereon;

[0019] Step two, assembling leak-proof glue foam to the connector on the PCBA board;

[0020] Step three, assembling the PCBA board into the bottom shell, so that the leak-proof glue foam is in close contact with the bottom shell;

[0021] Step four, assembling the upper cover with the bottom shell to enclose the PCBA board;

[0022] Step five, passing the connector wire through the upper cover and connecting it with the connector on the PCBA board to complete the circuit connection;

[0023] Step six, performing glue pouring treatment on the area where the connector wire passes through to ensure the sealing performance of the area to achieve waterproof effect;

[0024] Step seven, testing the sealing performance of the device after glue pouring to ensure that it meets the air tightness requirements.

[0025] As a preferred technical solution, the leak-proof glue foam is pre-compressed before being assembled to the PCBA board to ensure its sealing effect.

[0026] The beneficial effects of the present application are: the present application externally connects the connector module and adopts integrated modular design, so that the assembly process is more simple and efficient, and the cumbersome steps of threading the cable to the rubber part are reduced, thereby significantly improving the assembly efficiency. Secondly, the setting of the leak-proof glue foam can effectively alleviate the deformation problem of the rubber part caused by the cable pulling, and ensure the waterproof and sealing performance in the long-term use. At the same time, the sealing treatment is carried out by using the pouring sealant, which enhances the air tightness and protection ability of the whole device, especially suitable for new energy automobile electronic lock and other application scenarios which require high strength sealing. In addition, the present application reduces the error of human operation through the design of automatic assembly process, improves the consistency and quality stability of the product, and reduces the production cost, and has wide market application prospect.

[0032] All features disclosed in this specification, or the steps of any method or process disclosed, can be combined in any manner, except where features or steps are mutually exclusive.

[0033] Any feature disclosed in this specification, unless stated otherwise, can be replaced by an alternative feature serving the same, or a similar, purpose. That is, unless stated otherwise, each feature disclosed is one example only of a generic series of equivalent or similar features.

[0034] As shown in Figure 1 and Figure 2 , the present application provides a new type of locking device cable out line structure, which is designed by externally connecting the connector and the integrated modular assembly method, which significantly improves the assembly efficiency and ensures the sealing performance of the device.

[0035] The PCBA board 2 in the cable outlet structure is provided with an external connector. Compared with the traditional built-in design, the external connector can reduce the internal space occupation, make the assembly and maintenance more convenient, and improve the compactness of the overall structure.

[0036] The shell part is composed of a bottom shell 5 for accommodating the PCBA board 2 and an upper cover 1 matched with the bottom shell 5 to close the PCBA board 2 and fixed by a buckle structure or a screw assembly method. Flexible assembly options can be provided, the buckle structure simplifies the assembly process, and the screw assembly improves the firmness and stability of the structure, which is suitable for different application scenarios.

[0037] The leak-proof glue foam 3 is arranged between the connector and the bottom shell 5 to ensure the sealing effect. The foam is made of high-weather-resistant material and can maintain good waterproof and airtight performance in long-term use, avoiding sealing failure caused by cable pulling or external environmental changes. The leak-proof glue foam 3 can also be pre-compressed during assembly to further enhance its close fit with the shell and ensure the sealing effect.

[0038] The connector wire 4 passes through the upper cover 1 and is connected with 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 performance, the area where the connector wire 4 passes through is sealed by pouring glue. Preferably, silicone or epoxy resin materials are used. The pouring glue not only prevents water but also effectively resists external corrosion and vibration, ensuring the service life of the electronic lock in harsh environments.

[0039] After assembly, the sealing performance of the pouring glue sealing area is tested to ensure that it meets the airtightness standard. The test can be performed by airtightness detection equipment to verify whether the waterproof and sealing performance of the device meets the requirements. In addition, underwater immersion or high-pressure environment testing can be used to further ensure the durability and reliability of the product.

[0040] The beneficial effects of the present application are: by placing the connector module outside and using integrated modular design, the assembly process is more convenient and efficient, and the cumbersome steps of threading the cable into the rubber part are reduced, thereby significantly improving the assembly efficiency.

[0041] Secondly, the setting of the leak-proof glue foam 3 can effectively alleviate the deformation problem of the rubber part caused by cable pulling, ensuring the waterproof and sealing performance in the long-term use process.

[0042] At the same time, the pouring glue is used for sealing treatment, which enhances the airtightness and protection ability of the whole device, and is especially suitable for new energy vehicle electronic locks and other application scenarios that require high-strength sealing.

[0043] In addition, the application reduces the error of manual operation by designing an automatic assembly process, improves the consistency and quality stability of products, and reduces the production cost, and has a wide market application prospect.

[0044] The above is only a specific embodiment of the application, but the protection scope of the application is not limited thereto, any change or replacement without creative labor should be covered in the protection scope of the application. Therefore, the protection scope of the application should be limited by the protection scope defined in the claims.
