[0001] The utility model relates to the technical field of engine hoods, in particular to an engine hood assembly with supporting auxiliary tools. Background Art

[0002] The engine is one of the most important parts of a car. It is installed in the front of the car and protected by the front cover of the car to prevent the engine from being exposed outside the car. Now most cars will have an engine hood installed on the engine to protect the engine. It prevents dust, moisture and other impurities from entering the engine compartment and avoids parts damage, especially in harsh working environments. In addition, the engine hood can reduce the noise generated by the engine and improve driving comfort. The engine hood is made of soft materials, which can provide a certain buffering protection for the engine when it is hit.

[0003] Its specific structure is an engine hood assembly with supporting aids proposed by patent number CN217945332U. The protective hood is strengthened in stability by adding threaded rods to form a triangle and is fixed with bolts. Then, a spring is arranged on the reinforcement plate to make the engine hood elastic and provide a certain buffering protection for the engine.

[0004] Through the above configuration, the prior art hood assembly with supporting auxiliary tools plays a certain buffering and protective role on the hood and the front cover by adding a triangular fixing plate and a spring on the hood. However, the prior art hood assembly with supporting auxiliary tools has the following defects during operation:

[0005] (1) The engine hood assembly with supporting auxiliary equipment needs to be fixed by bolts next to the fixing plate to form a triangular fixing plate. In addition, the spring on the fixing plate cannot be adjusted at any time after the fixing plate is fixed, and the position cannot be adjusted according to different car front covers. Utility Model Content

[0006] The utility model is intended to provide an engine hood assembly with supporting auxiliary devices, which is mainly used to solve the technical problem that the engine hood assembly needs to be fixed by bolts beside a fixing plate to form a triangular fixing plate after fixing, and the spring on the fixing plate cannot be adjusted at any time after the fixing plate is fixed, and cannot be used to adjust the position according to different automobile front covers.

[0007] In order to solve the above technical problems, the utility model provides the following technical solutions:

[0009] The working principle and beneficial effects of the utility model:

[0010] 1. Working principle: Gears and racks are set on the engine hood. When the rack rotates, the rack moves left and right in a targeted manner due to the meshing relationship. After the spring on the rack moves to the required position, the pressing spring under the gear lifts up the second limit rod to limit it, preventing the gear from continuing to rotate and causing the spring on the rack to deviate.

[0011] 2. Beneficial effects:

[0012] (1) The prior art provides a certain buffering and protective effect on the engine hood and the front cover by adding a triangular fixing plate and a spring to the engine hood. The present invention provides a gear and a rack on the engine hood. When the rack rotates, the rack moves left and right in a targeted manner due to the meshing relationship. After the spring on the rack moves to the required position, the pressing spring under the gear lifts up the second limit rod to limit it, thereby preventing the gear from continuing to rotate and causing the spring on the rack to deviate.

[0013] Preferably, the length of the gear rod is less than half the length of the spring, so as to prevent the gear rod from being too long and being lifted up during driving and causing damage to the front cover of the car.

[0014] Preferably, the rack is arranged in the middle of the engine hood, and the middle arrangement can provide more space for the rack to move left and right to adjust its position.

[0015] Preferably, the front end of the first limiting rod is configured as an L-shaped protrusion, and the first limiting rod can prevent the rack from falling off due to lack of restriction.

[0016] Preferably, the first and second limiting grooves are configured to be convex, and the protruding front ends of the first limiting rod and the second limiting rod can clamp the protruding positions inside the first limiting groove and the second limiting groove to prevent the rack and the gear from falling off due to lack of restriction.

[0017] Preferably, the top end of the pressure spring contacts the bottom end of the second limiting rod, and the pressure spring can keep the second limiting rod lifted to increase resistance, thereby preventing the gear connected to the second limiting rod from rotating continuously.

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.

[0024] like Figure 1-Figure 4 As shown, the engine hood 1 has a rotating gear 2 symmetrically arranged on the top of the engine hood 1, a gear rod 3 is inserted at the top of the rotating gear 2, a rack 4 is meshed with the outer ring of the rotating gear 2, a spring 5 is fixedly installed at the top of the rack 4, a first limiting groove 11 is opened inside the engine hood 1 and is below the rack 4, a first limiting rod 6 is arranged at the bottom of the rack 4 and is in the first limiting groove 11, a second limiting groove 7 is opened inside the engine hood 1 and is below the rotating gear 2, a gear column 8 is arranged inside the second limiting groove 7 and the rotating gear 2 is installed at the top, a pressure spring 9 is fixedly installed at the bottom of the second limiting groove 7 and is installed on the outer ring of the gear column 8, and a second limiting rod 10 is arranged at the bottom of the gear rod 3;

[0025] like Figure 1-Figure 4As shown, the length of the gear rod 3 is less than half the length of the spring 5, and the gear rod is prevented from being too long and being lifted up during driving and causing damage to the front cover of the car. The rack 4 is arranged in the middle of the engine hood 1. The middle arrangement can have more space for the rack to move left and right to adjust its position when moving. The front end of the first limit rod 6 is arranged to be an L-shaped protrusion, and the first limit rod can prevent the rack from falling off due to lack of restriction. The first limit groove 11 and the second limit groove 7 are arranged to be convex, and the front end protrusions of the first limit rod and the second limit rod can clamp the protruding positions inside the first limit groove 11 and the second limit groove 7 to prevent the rack and the gear from falling off due to lack of restriction.
