A second insert shaft 8 is detachably inserted into the second mounting hole 103, the second through hole 203 and the second rotating hole 4011.

[0036] like Figures 1-8As shown, a first positioning plate 204 and a second positioning plate 205 are respectively provided on both sides of the cover plate 2. The first positioning plate 204 and the second positioning plate 205 are respectively provided with a first limiting groove 2041 and a second limiting groove 2051. A first pin 104 and a second pin 105 are respectively provided on both sides of the upper side of the mounting plate 1. The first pin 104 and the second pin 105 are respectively inserted into the first limiting groove 2041 and the second limiting groove 2051. The pins and the limiting grooves cooperate to limit the cover plate 2, and they will not slide relative to each other during use.

[0037] Furthermore, such as Figures 1-8 As shown, the first reset elastic element 5 and the second reset elastic element 6 are sleeved on the first insertion shaft 7 and the second insertion shaft 8. The fixed end of the first reset elastic element 5 is connected to the first insertion pin 104, and the free end of the first reset elastic element 5 abuts against the pulling part 302. The clamping plate 4 is provided with a first connecting hook 408. The fixed end of the second reset elastic element 6 is connected to the first insertion shaft 7, and the free end of the second reset elastic element 6 abuts against the first connecting hook 408. During the rotation of the stop grip, the pulling part 302 compresses the free end of the first reset elastic element 5, and during the rotation of the clamping plate 4, the first connecting hook 408 compresses the free end of the second reset elastic element 6, so that the stop plate and the clamping plate 4 are reset. The structure is compact and reasonable, and the operation is convenient. Specifically, the first reset elastic element 5 and the second reset elastic element 6 adopt a reset torsion spring. The free end and the fixed end of the first reset elastic element 5 are hook-shaped structures, the free end of the second reset elastic element 6 is arc-shaped and matches the first insertion shaft 7, and the fixed end of the second reset elastic element 6 is zigzag-shaped, making installation and disassembly more convenient.

[0038] like Figures 1-8 As shown, the upper part of the clamping plate 4 is provided with a lifting part 406, which can lift the engine hood. Furthermore, the lifting part 406 is provided with a first clearance groove 407 on the side facing the stop claw 3, and a second clearance groove 305 is provided through the upper part of the stop claw 3. The stop claw 3 is provided with a limiting part 306. The first clearance groove 407 cooperates with the first rotating part 301 to prevent damage to the clamping plate 4 during use, and the second clearance groove 305 prevents the lifting part 406 from interfering with the stop claw 3.

[0039] like Figures 1-8 As shown, the first reset elastic member 5 and the second reset elastic member 6 are sleeved on the first insertion shaft 7 and the second insertion shaft 8. The fixed end of the first reset elastic member 5 is connected to the first insertion pin 104, and the free end of the first reset elastic member 5 abuts against the pulling part 302. The card plate 4 is provided with a first connecting hook 408. The fixed end of the second reset elastic member 6 is connected to the first insertion shaft 7, and the free end of the second reset elastic member 6 abuts against the first connecting hook 408.

[0040] like Figures 1-8 As shown, the lower part of the pulling part 302 is provided with a second connecting hook 304 for connecting the pull wire, which facilitates the connection of the pull wire for pulling.

[0041] like Figures 1-8 As shown, the first pin 104 and the second pin 105 are respectively fitted with a first shock-absorbing pad 10 and a second shock-absorbing pad 11. When the stop claw 3 is reset, it contacts the first shock-absorbing pad 10, and when the locking plate 4 is reset, it contacts the second shock-absorbing pad 11. The first shock-absorbing pad 10 and the second shock-absorbing pad 11 have a buffering and shock-absorbing effect, which significantly reduces the impact force when resetting, thereby reducing the impact noise when the lock body device is opened and closed.

[0042] like Figures 1-8 As shown, the lock body device also includes a micro switch 9 with a micro lever 901. The micro switch 9 is detachably connected to the mounting plate 1. The second rotating part 401 is provided with a contact part, which cooperates with the micro lever 901. The wiring harness 12 of the micro switch 9 is tied with a cable tie 13. After the engine hood is opened, the micro switch 9 contacts the contact part and provides feedback, indicating that the engine hood is open, attracting the driver's attention, avoiding unnecessary risks, and improving the user's sense of security.

[0043] like Figures 1-8 As shown, the mounting plate 1 has a movable groove 106 on the side facing the stop claw 3, and the free end of the first reset elastic member 5 moves within the movable groove 106.

[0044] like Figures 1-8 As shown, the working process of the lock body device provided in a preferred embodiment of this utility model is as follows:

[0045] When the lock body is fully open (when the second lock is open), the stop part 303 is located below the second abutment part 404. After inserting the latch, as shown... Figure 6 As shown, the latch pushes the first abutment part 403 downward to rotate, the first connecting hook 408 compresses the second reset elastic member 6, the second abutment part 404 pushes the stop part 303 downward to rotate, the second connecting hook 304 rotates to the left to compress the first reset elastic member 5, when the latch enters the locking groove 402, the stop part 303 enters the stop groove 405, the elastic force of the first reset elastic member 5 causes the stop part 303 to abut against the second abutment part 404, as... Figure 5 As shown, the lock body is in a semi-locked state. The latch continues to push the first abutment part 403 downward. The first abutment part 403 rotates downward, pushing the stop part 303 to rotate. The second connecting hook 304 rotates to the left, compressing the first reset elastic member 5. When the first abutment part 403 rotates to below the stop part 303, the elastic force of the first reset elastic member 5 causes the stop part 303 to abut against the upper side of the first abutment part 403. Figure 3 As shown, the latch is fully engaged in the locking groove 402, the latch is fully locked, and the lock body device is in a fully locked state.

[0046] When the engine hood needs to be opened, the driver pulls the wrench for the first time from the cab. The cable on the wrench pulls the pulling part 302 to the left, disengaging the stop part 303 from the first abutment part 403. Due to the elastic force of the second reset elastic member 6, the first abutment part 403 and the second abutment part 404 rotate upward. During this process, the limiting part 306 abuts against the lifting part 406 to prevent the locking plate 4 from directly resetting. Continuing to pull the cable on the wrench, the stop part 303 enters the stop groove 405. Releasing the wrench, the elastic force of the first reset elastic member 5 causes the stop part 303 to abut against the second abutment part 404. Figure 5 As shown, the first lock is opened;

[0047] The driver pulled the wrench a second time in the cab, and the cable pulled the pulling part 302 to the left, as... Figure 6 As shown, the second abutting part 404 disengages from the stop part 303, and the elastic force of the second reset elastic member 6 drives the locking plate 4 to rotate and reset. The lifting part 406 lifts the engine hood, and the latch completely disengages from the locking groove 402. Figure 7 As shown, when the wrench is released, the first reset elastic element 5 drives the stop pawl 3 to reset, and the second lock is opened.

[0048] If the driver closes the hood with excessive force, the locking mechanism may fail, such as... Figure 8 As shown, the first clearance groove 407 cooperates with the first rotating part 301.

[0049] The driver no longer needs to unlock the first lock in the cab and then move to the delocking device to unlock the second lock, making it more convenient to use.

[0050] The above embodiments are merely descriptions for clearly illustrating the present utility model, and are not intended to limit the implementation. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all implementations here, and the obvious variations or modifications derived therefrom are still within the protection scope of the present utility model.
