[0018] In order to better understand the above technical solution, the above technical solution will be described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0019] A novel lever-type limited two-stage opening hood lock body assembly comprises a lock base plate 1 and a cover plate 8, wherein a pawl 2 and a ratchet 3 are arranged between the lock base plate 1 and the cover plate 8, wherein the pawl 2 and the ratchet 3 are fixed to the lock base plate 1 and the cover plate 8 via a pawl shaft 4 and a ratchet shaft 5, wherein a pawl spring 6 and a ratchet spring 7 are arranged on the pawl shaft 4 and the ratchet shaft 5 respectively, and a hook foot 201 is arranged on the pawl 2.

[0020] The hook foot 201 is arranged at one end of the pawl 2 and is integrated with the pawl 2, and the hook foot 201 is triangular in shape as a whole; a linkage angle 202 is arranged in the middle of the pawl 2, and a linkage angle 1 301 and a paddle angle 2 302 are arranged on the ratchet 3, and the linkage angle 202 is meshed with the linkage angle 1 301 and the paddle angle 2 302, and the hook foot 201 cooperates with the linkage angle 1 301; the ratchet shaft 5 and the pawl shaft 4 are connected to the lock base plate 1 and the lock base plate 1 by riveting. The cover plates 8 are connected and fixed, and the lock base plate 1 and the cover plate 8 are provided with rivet grooves matching with the ratchet shaft 5 and the pawl shaft 4; the pawl shaft 4 and the ratchet shaft 5 are provided with circular shaft rings, and the shaft rings are close to the pawl spring 6 and the ratchet spring 7, one end of the pawl spring 6 is close to the pawl 2, and the other end is close to the lock base plate 1, one end of the ratchet spring 7 is fixed in the spring hole on the ratchet 3, and the other end is close to the lock base plate 1; the pawl 2 and the ratchet 3 are in the same horizontal plane and match each other.

[0021] When the hood lock is open:

[0022] like Figure 2 As shown, when the user opens the hood lock handle for the first time, the pawl 2 rotates counterclockwise around the pawl shaft 4, and the pawl 2 rotates to disengage from the ratchet wheel 3;

[0023] like Figure 3 As shown, the ratchet 3 will rotate counterclockwise around the ratchet shaft 5 from the fully locked position under the elastic force of the ratchet spring 7, and the hook foot 201 on the pawl 2 will press against the paddle to limit the position, and the hook foot of the pawl 2 will move like a lever and limit the rotation of the ratchet 3;

[0024] like Figure 4 As shown, release the hood lock opening handle, the pawl 2 will rotate clockwise to reset under the elastic force of the pawl spring 6, and at the same time, the hook foot of the pawl 2 will disengage from the ratchet 3, and the ratchet 3 will continue to rotate counterclockwise under the elastic force of the ratchet spring 7 until the second pick angle 302 of the ratchet 3 and the linkage angle 202 of the pawl 2 are engaged for the second time, forming a double lock function;

[0025] like Figure 5 As shown, the user opens the cover lock handle for the second time, and the pawl 2 rotates counterclockwise around the pawl shaft 4 until the pawl 2 is disengaged from the ratchet wheel 3.

[0026] like Figure 6 As shown, the ratchet 3 will rotate counterclockwise around the ratchet shaft 5 from the second lock position under the elastic force of the ratchet spring 7 until the ratchet 3 is in the fully open position. The user releases the hood lock opening handle, and the pawl 2 rotates clockwise under the elastic force of the pawl spring 6 to return to the initial position.

[0027] To sum up, the function of opening the hood lock twice can be realized, and the two-lock function standard of the hood lock can be met; the original action of opening the hood lock once and pulling out the safety hook twice is changed to opening the hood lock twice in a row, eliminating the action of pulling out the safety hook twice, simplifying the action of opening the engine hood, and avoiding the need for users to blindly pull the handle of the safety hook with their fingers, providing users with a convenient and reliable operation experience, thereby improving user satisfaction.
