Technical Field

The utility model relates to an automobile cable technical field specifically says a car engine bonnet lock cable mechanism.

Background

A cable generally includes a steel cable and a sleeve, also called a hose, which is sleeved outside the steel cable. The traditional automobile engine hood lock stay cable mechanism comprises a first steel wire rope and a second steel wire rope, wherein one end of the first steel wire rope is connected with an operating lever of a cab such as a release lever, the second steel wire rope is connected with the other end of the first steel wire rope, the other end of the second steel wire rope is connected with a clamping structure of an engine hood lock, and the operating lever pulls the first steel wire rope and the second steel wire rope and operates the engine hood lock through the clamping structure to open or release the engine hood so that the engine hood lock and the engine hood can be pressed and locked.

However, in some cases, such as when the hood has a large volume and a heavy weight, it is difficult to satisfy the opening of the hood lock and the hood with only one engaging structure and only the first wire rope and the second wire rope or to satisfy the operation of opening or locking the hood lock without being tightened.

The technical staff improves the above, for example, the invention patent application with the application publication number of CN 102704265a discloses an engine hood cable mechanism or an automobile engine hood lock cable mechanism, which includes a first cable wire of a first cable, a second cable wire of a second cable, and a third cable wire of a third cable, one end of the first cable wire is connected to an operating lever, the other end of the first cable wire is connected to one end of the second cable wire and one end of the third cable wire, the other ends of the second cable wire and the third cable wire are respectively connected to two clamping structures of an engine hood lock, and the operating lever pulls the respective clamping structures through the first cable wire and the second cable wire to open the respective engine hood lock, so as to open the engine hood or lock the engine hood lock under the condition of no tension.

However, the automobile engine hood lock cable mechanism in the prior art has the following defects: 1. the first steel wire rope, the second steel wire rope and the third steel wire rope are exposed outside, and compared with an engine body, the steel wire rope of the stay cable can not be pulled and further the engine hood lock can not be opened, namely the engine hood can not be opened frequently after the first steel wire rope, the second steel wire rope and the third steel wire rope are frozen together by water in winter, particularly in northern car washing and the like. 2. The guiding performance of the connecting part of the first steel wire rope, the second steel wire rope and the third steel wire rope is poor. 3. In some cases, if the positions of the first cable and the second cable need to be exchanged according to different requirements such as the limitation of an installation site, the positions of the active steel wire rope and the passive steel wire rope at the connection part can be exchanged, and the exchange is difficult due to the fact that the connection part is fixedly connected in the prior art. 4. The phenomenon that the normal opening and locking of an engine hood lock and an engine hood are affected because the service life is long and the axial stroke is prolonged after the steel wire rope is fatigued and the steel wire rope is pulled but the clamping structure cannot be opened often occurs.

SUMMERY OF THE UTILITY MODEL

The to-be-solved technical problem of the utility model is to provide a wire rope's of cable connection avoids freezing and can normally control the automobile engine bonnet lock cable mechanism of opening and closing of engine bonnet winter.
