Description

Technical Field

[0001] The utility model relates to the technical field of automobile engine protection structures, in particular to an engine bottom protection plate. Background Art

[0002] The engine of a car is the core component of the car. It is usually installed in the engine compartment at the head of the car. The bottom of the engine usually extends beyond the bottom of the engine compartment. In order to prevent the engine from bottoming out or being hit by impurities such as stones flying from the road, a protective plate is usually installed at the bottom of the engine compartment (the car may have a protective plate added when it leaves the factory, but it may be plastic, so a metal protective plate is usually required). The protective plate can provide certain protection for the engine. At the same time, in order not to affect the heat dissipation of the engine, the protective plate also needs to be provided with heat dissipation holes. However, in actual use, small stones flying from the road may still enter the top of the protective plate through the heat dissipation holes, or get stuck in the heat dissipation holes, thereby causing adverse effects on the normal operation of the engine (such as being unable to smoothly leave the top of the protective plate, and repeatedly colliding with the engine, which will also cause abnormal impact noises from the bottom of the engine compartment, and those stuck in the heat dissipation holes may affect the normal heat dissipation function). Utility Model Content

[0003] In view of the deficiencies in the prior art, the utility model provides an engine bottom protective plate, which solves the problem in the prior art that the heat dissipation through holes on the protective plate may allow impurities such as pebbles to enter the top of the protective plate and cause adverse effects.

[0004] According to an embodiment of the utility model, a protective plate at the bottom of an engine includes a protective plate with a front side and a back side, a plurality of heat dissipation holes are opened on the protective plate, and a plurality of protective covers corresponding to each heat dissipation hole are fixedly arranged on the back side, and the downward orthographic projection of each heat dissipation hole is respectively located in the corresponding protective cover and connected with the corresponding protective cover, and the protective cover also has an opening located obliquely below and staggered with the corresponding heat dissipation hole.

[0005] In the above embodiment, a protective cover is provided below the heat dissipation through hole to block the heat dissipation through hole directly below, so that impurities such as pebbles are not easy to enter, and are less likely to reach the top of the protective plate, thereby reducing the probability of adverse effects. This solves the problem in the prior art that the heat dissipation through hole on the protective plate may allow impurities such as pebbles to enter the top of the protective plate and cause adverse effects.

[0006] Furthermore, all heat dissipation holes are arranged in regular rows and columns and all openings face the same direction.

[0007] Furthermore, an air inlet is arranged at a lowered position at one end of the front side facing away from all the openings.

[0008] Furthermore, a reinforcing transverse rib is convexly arranged on the front side and located between two adjacent rows of heat dissipation holes.

[0009] Furthermore, buffer pads are fixedly connected to the four corners of the front surface, and a side of the buffer pad facing away from the front surface is higher than the reinforcing transverse ribs.

[0010] Furthermore, the protective plate is also fixedly connected with connecting ears located outside the four corners thereof.

[0011] Furthermore, an arc-shaped guide surface is provided in the protective cover, extending from the edge of the corresponding heat dissipation through hole to the lower edge of the corresponding opening.

[0012] Furthermore, an oil drain port is provided on the protective plate, and a cover plate covering the oil drain port is detachably connected to the back side.

[0013] Compared with the prior art, the utility model has the following beneficial effects:

[0014] The protective cover provided below the heat dissipation through-hole blocks impurities such as pebbles from passing upward, thereby reducing the probability of impurities entering the top of the protective plate, resulting in a reduced probability of adverse effects. This solves the problem in the prior art that the heat dissipation through-hole on the protective plate may allow impurities such as pebbles to enter the top of the protective plate and cause adverse effects.

[0020] The technical solution of the present utility model is further described below in conjunction with the accompanying drawings and embodiments.

[0021] In the description of the present invention, it should be understood that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", "clockwise", "counterclockwise", "axial", "radial", "circumferential" and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the referred device or element must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present invention.

[0022] like Figure 1-3 As shown, the present embodiment provides an engine bottom protective plate, which includes a protective plate 1 provided with a front side 2 and a back side 3, a plurality of heat dissipation holes 4 are opened on the protective plate 1, and a plurality of protective covers 5 corresponding to each heat dissipation hole 4 are fixedly provided on the back side 3, and the downward orthographic projection of each heat dissipation hole 4 is respectively located in the corresponding protective cover 5 and connected with the corresponding protective cover 5, and the protective cover 5 also has an opening 6 located obliquely below and staggered with the corresponding heat dissipation hole 4, and all the heat dissipation holes 4 are arranged in regular rows and all the openings 6 are facing the same direction.

[0023] In the above embodiment, a protective cover 5 is provided below the heat dissipation through hole 4 to block impurities such as pebbles from entering directly below the heat dissipation through hole 4, thereby making it less likely for impurities such as pebbles to enter the top of the protective plate 1, thereby reducing the probability of adverse effects. This solves the problem in the prior art that the heat dissipation through hole 4 on the protective plate 1 may allow impurities such as pebbles to enter the top of the protective plate 1 and cause adverse effects. The protective cover 5 is provided below the back surface 3, and the opening 6 is provided on the side of the protective cover 5, so that the flying pebbles are less likely to enter the opening 6. Specifically, during the installation process, all openings 6 are facing one side, and the direction of travel of the car ( Figure 1 , 2(as shown by the arrow in the middle) In contrast to the opening 6, an end of the front face 2 facing away from all the openings 6 is sunken and provided with an air inlet 7, so that when the car is moving, the airflow can enter from the upper air inlet 7 of the protective plate 1, and the protective cover 5 below can cause a negative pressure area 8 to be generated on one side of the opening 6, so that the airflow entering from the top passes downward through the heat dissipation through hole 4 into the protective cover 5, and then leaves from the opening 6, while taking away the heat from the engine compartment, achieving a better heat dissipation effect; more specifically, the protective cover 5 is provided with an arc-shaped guide surface 9 extending from the edge of the corresponding heat dissipation through hole 4 to the lower edge of the corresponding opening 6, and the guide surface 9 can make the airflow pass more smoothly through the protective cover 5 to the opening 6, and then leave, and at the same time, this also makes the shape of the protective cover 5 opposite The corresponding streamline arc can divert the airflow below the back side 3 when the car is moving, and better form a negative pressure area 8 at the opening 6, thereby guiding the airflow above the front side 2 to move downward; in more detail, in order to facilitate the installation of the protective plate 1, it is also fixedly connected with connecting ears 10 located outside the four corners thereof (through the connecting holes provided on the connecting ears 10, similar to the prior art, the protective plate can be installed using connecting parts, such as bolts, etc. (usually, mounting holes are reserved on the car)), and at the same time, an oil drain port 11 is also provided on the protective plate 1, and a cover plate 12 covering the oil drain port 11 is also detachably connected to the back side 3, and the cover plate 12 can be connected by bolts 13, etc., so that the engine oil can be drained through the oil drain port 11 when the car is maintained.

[0024] In a more detailed exemplary scheme, the front side 2 is also convexly provided with reinforcing transverse ribs 14 located between two adjacent rows of heat dissipation holes 4, so that the strength of the protective plate 1 can be higher, and buffer pads 15 (such as rubber pads) are also fixedly connected to the four corners of the front side 2, and the side of the buffer pad 15 facing away from the front side 2 is higher than the reinforcing transverse ribs 14. After installation, the buffer pad 15 is higher than the reinforcing transverse ribs 14, which can prevent the reinforcing transverse ribs 14 from contacting the upper structure, thereby avoiding unnecessary collisions.

[0025] At the same time, the protective cover 5 provided in the present solution can also prevent splashing water from entering the top of the protective plate 1 through the heat dissipation holes 4. Even if some water enters the top of the protective plate 1 through the air inlet 7 or other parts, it will be blocked by the reinforcing cross ribs 14, and the water will gather toward the surrounding heat dissipation holes 4, and then enter the heat dissipation holes 4 downward under the guidance of the airflow, and then leave faster through the protective cover 5 and the opening 6.

[0026] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the purpose and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
