[0021] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0022] A front hood lock with integrated left and right rudders, such as Figure 1-Figure 7 As shown, the front hood lock comprises a base plate 1, a cover plate 2, a ratchet hook 3, and a pawl 4. The ratchet hook 3 and the pawl 4 are rotatably disposed between the base plate 1 and the cover plate 2. The ratchet hook 3 and the pawl 4 cooperate with each other to achieve locking and unlocking of the front hood lock. The above structure is a conventional structure of the front hood lock and will not be described in detail here.

[0023] Specifically, it also includes a linkage mechanism 5, which includes a release rod 51, a reset member 52 and a push rod 53. The release rod 51 is rotatably set on the base plate 1, and the push rod 53 is slidably set on the base plate 1. One end of the push rod 53 is rotatably connected to the release rod 51, and the reset member 52 connects the release rod 51 and the base plate 1. The reset member 52 is used to provide a restoring force for the release rod 51; the other end of the push rod 53 contacts the pawl 4, and the push rod is used to drive the pawl 4 to rotate. When in use, Figure 1 As shown, if the pull direction is left, the cable connects to pawl 4, directly pulling pawl 4 to rotate and unlock the hood lock. If the pull direction is right, the cable connects to release lever 51, which rotates to move push rod 53 leftward, thereby driving pawl 4 to rotate and unlock the hood lock. This structure allows for left-side or right-side pulling according to actual needs, meeting the needs of both left-hand and right-hand drive vehicles.

[0024] In one embodiment, if Figure 1-Figure 7 As shown, the release lever 51 is rotatably connected to the rivet 54, and the rivet 54 is riveted to the base plate 1. The rivet 54 serves as a rotation axis of the release lever 51, guiding the release lever 51 to rotate back and forth.

[0025] In one embodiment, if Figure 1-Figure 7 As shown, the reset member 52 is a torsion spring. Specifically, the torsion spring is sleeved on the rivet 54, one end of which is connected to the release rod 51 and the other end is connected to the base plate 1, providing a force for the release rod 51 to rotate counterclockwise.

[0026] In one embodiment, if Figure 1-Figure 7 As shown, a limiting block 55 is convexly provided on the release lever 51, and a limiting groove 11 is provided at a corresponding position on the base plate 1, and the limiting block 55 is placed in the limiting groove 11. The limiting groove 11 and the limiting block 55 cooperate to limit the rotation angle of the release lever 51.

[0027] In one embodiment, if Figure 1-Figure 7As shown, a rotating portion 531 is protruded from one end of the push rod 53, and a first stopper 532 is provided on the rotating portion 531. A rotating hole 511 is provided on the release lever 51 to cooperate with the rotating portion 531, and a passage 512 is provided on the rotating hole 511 to allow the first stopper to pass through. When assembling the push rod 53 and the release lever 51, after aligning the first stopper 532 with the passage 512, the rotating portion 531 is inserted into the rotating hole 511 and rotated to achieve the connection between the rotating portion 531 and the rotating hole 511. Because the push rod 53 and the base plate 1 are connected in a sliding manner, the release lever 51 and the base plate 1 are connected in a rotational manner, and the rotation range of the release lever 51 is limited, after the push rod 53, the release lever 51 and the base plate 1 are assembled, the rotating portion 531 and the rotating hole 511 cannot rotate to the unlocked position, thereby ensuring the reliability of the connection between the push rod 53 and the release lever 51.

[0028] In one embodiment, if Figure 1-Figure 7 As shown, a guide portion 533 is protruding from the push rod 53, and a second stopper 534 is provided on the guide portion 533. A guide groove 12 is provided on the base plate 1. The guide portion 533 is slidably disposed within the guide groove 12, and the second stopper 534 is used to prevent the guide portion 533 from separating from the guide groove 12. When the push rod 53 is assembled with the base plate 1, the guide portion 533 and the second stopper 534 are aligned parallel to the guiding direction of the guide groove 12, so that the second stopper 534 passes through the guide groove 12. The guide portion 533 is then rotated and locked with the guide groove 12 by the second stopper 534. Furthermore, because the push rod 53 is restrained by the release lever 51, the reliable connection between the push rod 53 and the guide groove 12 is ensured.

[0029] The above are only preferred embodiments of the present invention and are not intended to limit the scope of implementation of the present invention. Without departing from the spirit and scope of the present invention, modifications or equivalent replacements of the present invention should be included in the scope of protection of the claims of the present invention.
