[0002] With the growth and expansion of the automotive market, in order to ensure the stability of the engine hood and driving safety during high-speed driving, more and more car engine hoods are adopting a dual-lock arrangement. The engine hood needs to unlock to open both locks simultaneously with a single unlocking. Therefore, it is necessary to develop a one-to-two cable mechanism to achieve simultaneous unlocking of both locks on the engine hood, thereby achieving the effect of simultaneous opening of both left and right sides of the engine hood.

[0003] Meanwhile, existing cable junction box structures, such as Figure 1 As shown, the two cables at the output end extend from the same side. When connected to the lock, one of the cables bends at a 90° angle. The small bending radius of the wire rope causes it to press tightly against the protective tube, increasing the unlocking force during the unlocking process. Simultaneously, the slippage of the wire rope causes wear on the protective tube, affecting the service life of the cable mechanism. Therefore, it is necessary to develop a cable-driven two-to-one structure for a double-lock hairnet to effectively solve the above problems. Summary of the Invention
