[0034] The engine inspection cover comprises a cover body 1, a protective outer plate 2 is arranged at the bottom of the cover body 1, a plurality of first ventilation slots 3 are evenly opened on the cover body 1, a plurality of second ventilation slots 4 are evenly opened on the protective outer plate 2, a plurality of arc-shaped protective plates 5 are evenly fixedly connected at the bottom of the cover body 1 and above the second ventilation slots 4, and the plurality of arc-shaped protective plates 5 and the plurality of first ventilation slots 3 are staggered;

[0035] The bottom of both ends of the arc-shaped protective plate 5 are fixedly connected with a protective net 6, the bottom of the protective net 6 is fixedly connected to the top of the protective outer plate 2, and a trapezoidal connecting piece 7 for connecting the cover plate body 1 and the protective outer plate 2 is fixedly connected between the cover plate body 1 and the protective outer plate 2.

[0036] like Figure 1 The cover body 1 and the protective outer plate 2 are both steel plates with high strength, which are convenient for providing protection for the engine. The installation position of the cover body 1 is located below the engine, which can provide protection for the engine. The arc-shaped protective plates 5 and the first air permeable slots 3 are staggered, and each first air permeable slot 3 has a corresponding arc-shaped protective plate 5, so that the second air permeable slot 4 and the first air permeable slot 3 are staggered, so that the first air permeable slot 3 and the second air permeable slot 4 are not located in the same vertical direction.

[0037] The cover plate body 1 and the protective outer plate 2 are connected by the trapezoidal connecting member 7 so that the cover plate body 1 and the protective outer plate 2 can form a whole, which is convenient for the joint transportation and installation of the cover plate body 1 and the protective outer plate 2.

[0038] Lateral protection mechanisms 8 are provided on both sides of the top of the cover body 1. The lateral protection mechanisms 8 include a protective inclined plate 81. The horizontal end of the protective inclined plate 81 is provided with an arc-shaped notch 82, and the inclined end of the protective inclined plate 81 is provided with a plurality of heat dissipation notches 83 in a linear array.

[0039] like Figure 1 , Figure 3 and Figure 4 The protective inclined plate 81 consists of two parts: a horizontal end and an inclined end. The horizontal end is attached to the top of the cover body 1, and the inclined end is inclined in a direction away from the cover body 1.

[0040] A clamping mechanism 9 is fixedly connected to both sides of the top of the cover body 1, and the clamping mechanism 9 includes a clamping plate 91, the top of the clamping plate 91 passes through the horizontal end of the protective inclined plate 81, and a through groove 92 is opened on one side of the clamping plate 91 and above the protective inclined plate 81, a partition plate 93 is fixedly connected to the center position of the inner wall of the through groove 92, a clamping spring 94 is fixedly connected to one side of the partition plate 93, and a clamping block 95 is fixedly connected to one end of the clamping spring 94.

[0041] like Figure 4 , Figure 5 and Figure 6 The two protective inclined plates 81 on both sides of the top of the cover body 1 can be clamped by a clamping mechanism 9 respectively, and there is an opening at the horizontal end of the protective inclined plate 81 to facilitate the clamping plate 91 to pass through.

[0042] The clamping plate 91 is fixed to the top of the cover body 1 , and one end of the clamping block 95 passes through the through slot 92 and is located above the protective inclined plate 81 , so as to press the protective inclined plate 81 onto the cover body 1 .

[0043] like Figure 5 and Figure 6 By pressing the clamping block 95 against the top of the protective inclined plate 81, the protective inclined plate 81 can be prevented from being separated from the cover plate body 1.

[0044] A limiting slide groove 10 is provided on one side of the clamping block 95 , and T-shaped rods 11 are fixedly connected to both sides of the partition plate 93 . One end of the T-shaped rod 11 extends into the limiting slide groove 10 and is slidably connected to the limiting slide groove 10 .

[0045] like Figure 6Through the sliding connection between the T-bar 11 and the limiting slide groove 10, the portion of the T-bar 11 extending into the limiting slide groove 10 can limit the maximum extension distance of the clamping block 95, so that a portion of the clamping block 95 is always located inside the through groove 92 when it is active.

[0046] Both sides of the top of the protective outer plate 2 are fixedly connected with a trapezoidal groove rail 12, and the top of the trapezoidal groove rail 12 is fixedly connected with a vertical connecting rod 13. The top of the vertical connecting rod 13 passes through the cover body 1 and the arc-shaped groove 82 in sequence and is fixedly connected with a fixing block 14, and a fixing hole 15 is opened on the fixing block 14.

[0047] like Figure 3 and Figure 4 The trapezoidal groove rail 12 is used as a support for the vertical connecting rod 13. The bottom of the trapezoidal groove rail 12 is a cavity, which facilitates the bottom of the protective outer panel 2 to be compressed and produce upward elastic deformation. The fixing block 14 can be fixed to other parts of the car through the fixing hole 15. The trapezoidal groove rail 12 and the protective outer panel 2 are connected by the vertical connecting rod 13, which can assist in the installation and fixation of the protective outer panel 2.

[0048] Four fixing blocks 16 are symmetrically fixedly connected to both sides of the top of the cover body 1 , and the fixing blocks 16 are used to assist in the installation and fixation of the cover body 1 .

[0049] like Figure 5 There is an opening on the fixing sleeve block 16, and the fixing sleeve block 16 is used to conveniently fix the protective outer panel 2 and other parts of the car.

[0050] A plurality of auxiliary blocks 17 are fixedly connected to the first vent slot 3 in a linear array, and auxiliary mounting screw holes 18 are provided on the auxiliary blocks 17 .

[0051] like Figure 5 By providing the auxiliary block 17 and the mounting screw hole 18 in the first vent slot 3, the cover body 1 can be conveniently fixed to the engine when providing protection for the engine, so that the fixation between the cover body 1 and the engine is more stable.

[0052] Auxiliary plates 19 are fixedly connected to both sides of the protective outer plate 2 , and auxiliary fixing screw holes 20 are opened on the auxiliary plates 19 .

[0053] like Figure 2 , the protective outer panel 2 is located at the bottom of the car, and the auxiliary plate 19 can assist in the fixation between the protective outer panel 2 and the bottom of the car.

[0054] The working principle of the engine inspection cover plate and the locking device thereof provided by the present invention is as follows:

[0055] The cover plate body 1 and the protective outer plate 2 are located at the bottom of the engine to provide protection for the engine. The bottom of the engine can interact with the space at the bottom of the car through the first ventilation slot 3 and the second ventilation slot 4 to improve the heat dissipation capacity of the cover plate body 1.

[0056] When the car passes through a puddle or other area, when water splashes upward from the bottom of the car, it will splash onto the outside of the protective outer plate 2, or splash onto the curved protective plate 5 through the second ventilation slot 4, and then drip from top to bottom, preventing the splashed water from contacting the engine through the first ventilation slot 3.

[0057] When the car is driving, the bottom of the vehicle is bumped, and the protective outer panel 2 will contact external objects. When the car is bumped, the bottom of the protective outer panel 2 is compressed and the upward elasticity provides buffer protection, further improving the protection capability of the bottom of the engine.

[0058] like Figure 1 , Figure 5 and Figure 6 When the clamping block 95 is pressed into the inside of the clamping plate 91, the clamping block 95 can be pressed into the inside of the clamping plate 91. At this time, the clamping plate 91 can be pulled upward to remove the protective inclined plate 81. Conversely, when the clamping block 95 is pressed into the inside of the clamping plate 91, the protective inclined plate 81 can be set above the cover body 1, so that the clamping plate 91 passes through the protective inclined plate 81, and then the clamping block 95 is released. At this time, the clamping spring 94 extends and pushes the clamping block 95, clamping the protective inclined plate 81 to the top of the cover body 1.

[0059] Compared with the related art, the engine inspection cover plate and the locking device thereof provided by the present invention have the following beneficial effects:

[0060] Through the double-layer design of the cover body 1 and the protective outer plate 2, while providing protection for the engine, the bottom protective outer plate 2 can be compressed to produce upward elastic deformation to play a buffering protection role, effectively providing protection for the engine, and through the first breathable slots 3 and the second breathable slots 4 staggered at different heights, the ventilation and heat dissipation capacity of the engine can be improved. The arc-shaped protective plate 5 located above the first breathable slot 3 can prevent the water below from splashing upward onto the engine. The protective nets 6 located on both sides of the bottom of the arc-shaped protective plate 5 can prevent debris from entering the area between the cover body 1 and the protective outer plate 2. While providing heat dissipation protection, it can also have a good waterproof effect.

[0061] The protective inclined plate 81 can provide protection for both sides of the engine, and the heat dissipation slots 83 can facilitate heat dissipation on both sides of the engine. Manually pressing the clamping block 95 into the inside of the clamping plate 91 can quickly and easily complete the installation and disassembly of the protective outer plate 2, making it convenient to inspect and maintain both sides of the engine.

[0062] Example 2

[0063] A locking device for an engine inspection cover plate also includes a locking bolt 21 for locking an auxiliary plate 19 , and a sealing gasket 22 is provided on the locking bolt 21 .

[0064] like Figure 2 and Figure 8 The area around the protective outer part of the bottom of the car is provided with screw holes that cooperate with the locking bolts 21. The locking bolts 21 can pass through the auxiliary fixing screw holes 20 to fix the auxiliary plate 19 to the bottom of the car, making the installation of the protective outer plate 2 and the cover body 1 more stable. At this time, the sealing gasket 22 is attached to the outside of the auxiliary fixing screw holes 20 to enhance the waterproof and dustproof capabilities of the auxiliary fixing screw holes 20.

[0065] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments, and the above embodiments and descriptions are only for explaining the principles of the present invention. Without departing from the spirit and scope of the present invention, the present invention may have various changes and improvements, and these changes and improvements all fall within the scope of the present invention to be protected.
