DETAILED DESCRIPTION

[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] The utility model provides Figure 1-4 The engine hood lock hook reinforcement plate structure shown in the figure comprises an engine hood 1 and a hood lock hook 2 fixedly connected to one side of the bottom surface of the engine hood 1. A reinforcement box 3 is provided at the bottom of the engine hood 1 on one side of the hood lock hook 2. A rotating rod 4 that can produce a clamping effect by using a rotary spring 402 is provided inside the reinforcement box 3. A reinforcement block 5 is fixedly connected to the bottom surface of the engine hood 1 on one side of the reinforcement box 3 to prevent the hood from suddenly opening when the car is driving. When the hood lock hook 2 at the bottom of the engine hood 1 suddenly fails, the reinforcement block 5 located on one side of the hood lock hook 2 will quickly The protruding block 501 is lifted up, so that the clamping block 405 provided on the bottom surface of the extension block 404 is quickly connected with the clamping block 405, so that the engine cover 1 forms a protective measure regardless of whether it is opened manually. However, when the clamping effect needs to be released, it is only necessary to pull the pull rod 406, so that the pull rod 406 drives the extension block 404 to move upward, so that the clamping effect between the clamping block 405 and the protruding block 501 is immediately released, avoiding the fact that most engine covers 1 do not have a protective measure for sudden opening, reducing the safety hazard when the car is in use, and providing a good driving experience for the driver.

[0022] like Figure 1-3 As shown, the reinforcement box 3 is arranged on one side of the bottom surface of the engine cover plate 1, and a working groove 301 is opened inside the reinforcement box 3, and an extension groove 302 is also opened on one side of the surface of the reinforcement box 3. Clamping columns 303 are provided on both sides of the inner wall of the working groove 301. The two clamping columns 303 clamp the two ends of the two rotation springs 402 respectively, and can be reset after the rotation rod 4 is rotated, and then prepare for the next protection measure. The two ends of the rotation rod 4 are rotatably connected to the two sides of the inner wall of the working groove 301, and the two sides of the rod wall of the rotation rod 4 are fixedly connected with the blocking blocks 401 to produce the blocking effect. The rod wall of the rotation rod 4 is located on both sides of the two blocking blocks 401 and is fixedly connected with the rotation springs 402. The two rotation springs One end of 402 is respectively clamped with the two clamping columns 303 in an interlaced manner, and the rod wall of the rotating rod 4 is located on the opposite side of the two blocking blocks 401 and is fixedly connected with a connecting block 403, and one side of the surface of the connecting block 403 is fixedly connected with an extension block 404, one end of the extension block 404 passes through the interior of the extension groove 302 and extends to the outside, and the bottom surface of the extension block 404 is fixedly connected with a clamping block 405, and one side of the surface of the extension block 404 is fixedly connected with a pull rod 406. When the protective measure of opening the engine cover 1 is started, the pull rod 406 can be toggled to make the pull rod 406 drive the extension block 404 to move upward, so that the clamping block 405 and the protruding block 501 at the bottom of the extension block 404 release the clamping effect.

[0023] like Figure 4 As shown, the reinforcing block 5 is fixedly connected to the bottom surface of the engine cover plate 1 on one side of the reinforcing box 3, and a protruding block 501 is fixedly connected to one side of the surface of the reinforcing block 5. The top surface of the protruding block 501 is provided with a clamping groove 502 matching the clamping block 405, and the clamping groove 502 can be paired with the clamping block 405 to produce a clamping measure for protection.

[0024] Working principle of the utility model: when the utility model is installed on the vehicle, if the driver is driving on a highway and the wind resistance is too large, and the engine cover 1 is about to be blown up or the cover lock hook 2 fails, the engine cover 1 will first be lifted up due to the blowing of the wind direction, and the reinforcing block 5 fixedly connected to the bottom surface of the engine cover 1 will first make the protruding block 501 move upward, and use the internally opened card slot 502 to match and clamp with the clamping block 405, so as to produce a protective measure;

[0025] However, when it is really necessary to open the engine cover 1 for maintenance or inspection, the cover lock hook 2 is released, and the protruding block 501 will still be clamped and paired with the pull rod 406. At this time, you only need to put your hand into the gap between the engine cover 1 and the car, and then use the pull rod 406 fixedly connected to the surface of the extension block 404 to move upward, so as to release the clamping effect between the protruding block 501 and the clamping block 405. However, while the pull rod 406 moves, the return spring 402 will also be tightened by rotation, which is ready for the next protection of the engine cover 1. The original text highlights the innovative structure and does not elaborate on the prior art.

[0026] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
