[0051] The working principle and beneficial effects of the above technical solution are:

[0052] Working principle: The transmission cylinder wire harness sealing structure provided in Example 1 of the present invention forms a complete sealing system by sequentially connecting the first-section sealing component 1, the extended connection component 2, the second-section sealing component 3 and the end sealing component 4. The first-section sealing component 1 is used as the starting point, and is connected to the second-section sealing component 3 through the extended connection component 2 at its bottom. The second-section sealing component 3 is used to connect to the cable through hole of the transmission, while the end sealing component 4 seals and protects the overall structure. This design ensures the sealing of the wire harness when passing through the transmission, prevents the infiltration of liquid or gas, and thus ensures the normal operation of the transmission and the durability of the wire harness.

[0053] Beneficial effects: The present invention effectively solves the problem of transmission cylinder wiring harness sealing and improves the reliability and stability of the sealing structure. At the same time, through modular design, installation and maintenance become more convenient, reducing maintenance costs and time. When testing is required, only the extended connection component 2 needs to be unscrewed for testing, avoiding the need to dismantle the entire transmission and sealing structure to test the wiring harness. In addition, the structure also has good adaptability and scalability, and can be adjusted and optimized according to different vehicle models and wiring harness specifications.

[0054] Embodiment 2, on the basis of embodiment 1, as Figure 1-Figure 4 As shown, the first section sealing assembly 1 includes: a partition 5 and an internally threaded tube 6, the center of the top of the partition 5 is fixedly connected to the vertical internally threaded tube 6, the center of the bottom of the partition 5 is fixedly connected to the vertical externally threaded tube 7, a plurality of vertical pins 8 are embedded in the partition 5, the pins 8 penetrate the partition 5 up and down, and a first rubber sealing sheet 9 is fixedly installed at the top of the partition 5 inside the internally threaded tube 6;

[0055] The bottom end of the partition 5 is located inside the external threaded tube 7 and a second rubber sealing sheet 10 is fixedly installed. The insertion pin 8 passes through the first rubber sealing sheet 9 and the second rubber sealing sheet 10 from top to bottom. The bottom of the external threaded tube 7 is fixedly connected with a raised sealing ring 11;

[0056] The end sealing assembly 4 includes: a connecting rope 38 and an end cover 39. The top of the partition 5 is connected to the end cover 39 through the connecting rope 38. The bottom center of the end cover 39 is fixedly connected to an external threaded pipe 40. The external threaded pipe 40 is threadedly connected to the internal threaded pipe 6. The end cover 39 is located outside the external threaded pipe 40 and is connected to an annular sealing piece 41. The end cover 39 has a fixed mounting bracket 42 inside. The bracket 42 is rotatably connected to a terminal plug 43. The terminal plug 43 is connected to the pin 8 for plugging and unplugging.

[0057] The working principle and beneficial effects of the above technical solution are:

[0058] Working principle: Based on Example 1, Example 2 further refines the structure of the first section sealing component 1 and the end sealing component 4. The first section sealing component 1 realizes the tight wrapping and sealing of the wiring harness through the components such as the partition 5, the internal threaded tube 6, the external threaded tube 7, the pin 8, the first rubber sealing sheet 9 and the second rubber sealing sheet 10. The end sealing component 4 seals and protects the overall structure through the components such as the connecting rope 38, the end cover 39, the external threaded tube 40, the annular sealing sheet 41, the bracket 42 and the end plug 43, while allowing the pin 8 to be plugged in and out of the wiring harness connector 15, which facilitates the connection and disconnection of the wiring harness (when the wiring harness of the present invention needs to be connected, the end plug 43 is opened so that the pin 8 is connected to the corresponding terminal head; when the wiring harness of the present invention needs to be disconnected, Figure 2 As shown, the pin 8 is sealed by the end plug 43);

The first rubber sealing sheet 9 plays a preliminary sealing role to prevent liquid or gas from penetrating from the gap between the internal threaded tube 6 and the wire harness. Then, the external threaded tube 7 is threadedly connected to the adjacent components (such as the extended connection component 2). At this time, the sealing ring 11 is in close contact with the sealing ring 18 (see the following embodiment 3 for details), forming a second layer of sealing. The second rubber sealing sheet 10 is located inside the external threaded tube 7, which further enhances the sealing effect;

[0060] After the installation of the first section sealing assembly 1 is completed, the end cap 39 is threadedly connected to the internal threaded pipe 1 6 through the external threaded pipe 2 40. The annular sealing sheet 2 41 is in close contact with the end surface of the partition 1 5 to form a third layer of sealing. The end plug 43 is plug-in connected to the pin 8, and the pin 8 is further fixed inside the end cap 39. When disconnection is required, the end plug 43 only needs to be pulled out from the pin 8, which is simple and quick to operate.

[0061] Beneficial effects: This technical solution further improves the sealing performance and stability of the sealing structure, ensuring the normal operation of the wiring harness in complex environments. At the same time, through the plug-in connection method, the connection and disconnection of the wiring harness becomes more convenient, improving work efficiency. In addition, the structure also has good durability and corrosion resistance, extending the service life.

[0068] Then, the harness cable 16 is connected to the mounting hole on the plugging tube 14 through the harness connector 15, and the top of the harness connector 15 is plugged and connected to the pin 8 to ensure the transmission of the electrical signal. The third rubber sealing sheet 35 is located inside the plugging tube 14, below the harness connector 15, and plays a sealing role to prevent liquid or gas from penetrating from the harness connector 15.

Then, the wiring harness cable 16 is clamped inside the clamping cylinder 20 using the clamping mechanism 22 to ensure that the wiring harness cable 16 will not loosen or fall off. The annular sealing sheet 1 25 ensures the sealing between the clamping cylinder 20 and the gearbox to prevent liquid or gas from penetrating from the connection (the cable hole of the gearbox body). The mounting bolts 24 fix the second section sealing assembly 3 to the gearbox to ensure the stability and reliability of the entire sealing structure.

[0070] Beneficial effects: This technical solution further enhances the reliability and stability of the sealing structure, ensuring the sealing performance of the wire harness during the extension process. At the same time, through the design of the clamping mechanism 22, the wire harness cable 16 is effectively fixed and protected, avoiding loosening or damage caused by vibration or external force.
