Technical Field

[0001] The present invention relates to the technical field of engine underbody shields, and particularly to an automotive engine underbody shield made of lightweight materials. Background Art

[0002] An engine underbody shield is an engine protection device designed specifically for various different vehicle models. Its design is primarily to prevent soil from covering the engine, which may cause poor engine heat dissipation. Secondly, it is to prevent the engine from being damaged due to impacts caused by uneven road surfaces during driving, thereby extending the service life of the engine and avoiding vehicle breakdowns caused by engine damage due to external factors during travel.

[0003] During the installation of existing engine underbody shields, they are generally fixed to the bottom plate by passing matching screws through the mounting holes. However, in this case, the application range of the engine underbody shield is relatively narrow, and it cannot adjust the size of the surface mounting holes according to the size of the mounting grooves on the bottom plate. Moreover, after the underbody shield is installed, the entire underbody shield needs to be removed when changing the engine oil, which is complex in operation and time-consuming and laborious.

[0004] In view of the above problems, the present invention proposes an automotive engine underbody shield made of lightweight materials. Summary of the Invention

[0005] The purpose of the present invention is to provide an automotive engine underbody shield made of lightweight materials, thereby solving the problems in the background art.

Fixing components are embedded at the four corners of the surface of the bottom plate. The fixing components have a central screw ring sleeve, and the central screw ring sleeve can adjust its position in the horizontal plane to align with the screw hole positions of the vehicle body.

[0008] The oil seal baffle plate can be rotated downward and opened relative to the bottom plate, forming a sealing effect when the upper end surface of the oil seal baffle plate is flush with the upper end surface of the bottom plate. In this state, the oil seal baffle plate is locked on the bottom plate.

[0009] As a further improvement of the present invention, the fixing components further include an outer ring sleeve that coincides with the axis of the central screw ring sleeve, and a number of groups of central positioning springs evenly and symmetrically distributed in the area between the outer ring sleeve and the central screw ring sleeve.

[0010] As a further improvement of the present invention, the upper end of the central screw ring sleeve has a horizontally extending web, and the diameter of the web is greater than the outer diameter of the outer ring sleeve, so that the web can press on the upper end of the outer ring sleeve.

[0011] As a further improvement of the present invention, the outer ring sleeve is connected to the bottom plate 1 by an elastic snap connection method.

[0012] As a further improvement of the present invention, pressing plates are provided on the bottom plate near each fixing component. The middle of the pressing plate has a guiding groove arranged horizontally, and the guiding groove has a structure similar to an inverted T shape.

DETAILED DESCRIPTION OF THE INVENTION

[0032] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0033] Please refer to Figures 1 to 6 As shown, an engine underbody shield for an automobile using lightweight materials includes a bottom plate 1 made of lightweight materials and an oil seal baffle 2 opened in the middle of the bottom plate 1. Fixed components 3 are embedded at the corners around the surface of the bottom plate 1. The fixed component 3 has a central screw ring sleeve 33, and the central screw ring sleeve 33 can adjust its position in the horizontal plane to align with the screw hole position of the vehicle body.

[0034] Based on this structural design, the present invention can adjust its position in the horizontal plane to align with the screw hole position of the vehicle body, so that fine adjustment of the position can be performed when the hole of the central screw ring sleeve 33 does not correspond to the threaded hole on the vehicle body, to ensure the smooth screwing in of the screw component, thereby effectively preventing the screw from being twisted or unable to be screwed in smoothly due to the misalignment of the screw holes.

[0035] As Figure 1 and Figure 5 shown, the oil seal baffle 2 can be rotated downward relative to the bottom plate 1 to open. When the upper end surface of the oil seal baffle 2 is flush with the upper end surface of the bottom plate 1, a sealing effect is formed, and in this state, the oil seal baffle 2 is locked on the bottom plate 1. The oil seal baffle 2 designed in the present invention mainly shields the oil port on the vehicle body to avoid damage to the oil port on the vehicle body caused by hard objects.

[0036] When the engine needs to change the oil, open the oil seal baffle 2 to expose the oil port on the vehicle body, and the operator can remove the plug of the oil port to change the oil.

[0037] As Figure 2 shown, the fixed component 3 of the present invention further includes an outer ring sleeve 31 that coincides with the axis of the central screw ring sleeve 33, and a number of groups of central positioning springs 32 evenly and symmetrically distributed in the area between the outer ring sleeve 31 and the central screw ring sleeve 33.

[0038] As Figure 2 and Figure 3As shown in the figure, in order to ensure that the bottom plate 1 is firmly fixed to the vehicle body by using a screw structure, the upper end of the central screw collar 33 designed by the present invention has a horizontally extending web 33a, and the diameter of the web 33a is larger than the outer diameter of the outer collar 31, so that the web 33a can press on the upper end of the outer collar 31. The outer collar 31 is connected to the bottom plate 1 by an elastic clamping method. In this way, when the screw passes through the central screw collar 33 and is tightened into the corresponding screw hole on the vehicle body, by means of the web 33a pressing tightly on the outer collar 31, and the outer collar 31 is elastically clamped to the bottom plate 1, the pressing force is applied to the bottom plate 1.

[0039] At each position on the bottom plate 1 close to the location of each fixing component 3, a pressing plate 101 is provided. The middle part of the pressing plate 101 has a horizontally arranged guiding groove 102, and the guiding groove 102 has a structure similar to an inverted T shape. A number of groups of tooth engaging grooves 103 are symmetrically provided on the inner side wall of the guiding groove 102.

[0040] As Figure 2 shown in the figure, a wing plate 34 is fixed on the outer side of the outer collar 31 of the present invention. The wing plate 34 is provided with a retractable tooth engaging part 36, and after the tooth engaging part 36 extends out, it is engaged into the tooth engaging groove 103 at the corresponding position.

[0041] As Figure 4 shown in the figure, the tooth engaging part 36 of the present invention is connected to the wing plate 34 by a compression spring 35. Such a structural design, on the one hand, can facilitate the contraction of the tooth engaging part 36 to extend into the guiding groove 102, and on the other hand, by means of the elastic restoring force of the compression spring 35, it is ensured that after the tooth engaging part 36 enters the guiding groove 102, it can smoothly pop out to be engaged into the tooth engaging groove 103 at the corresponding position.

[0042] As Figure 4 shown in the figure, one end of the wing plate 34 inserted into the guiding groove 102 has a pressing head 37, and the pressing head 37 is restricted in the guiding groove 102 with a structure similar to an inverted T shape and cannot move up and down, thus preventing the pressing head 37 from falling off in the up and down direction, ensuring the stability of the structural connection. At the same time, it can effectively transmit the pressing force brought by the screw to the bottom plate 1 through the pressing head 37.

[0043] As Figure 2 shown in the figure, specifically, at each position on the bottom plate 1 close to the location of each fixing component 3, an outer collar accommodating cavity 104 connected to the pressing plate 101 is provided. The outer collar 31 is accommodated in the outer collar accommodating cavity 104. An arc-shaped taking and placing groove 105 is provided on a side wall of the outer collar accommodating cavity 104 opposite to the pressing plate 101. The arc-shaped taking and placing groove 105 designed by the present invention is to provide enough space for the movement of the outer collar 31, ensure that the outer collar 31 can be conveniently pulled laterally to adjust the insertion position of the tooth engaging part 36; at the same time, it is also convenient to pull out the outer collar 31 when the central screw collar 33 is damaged, so as to facilitate replacement.

[0044] like Figure 5 As shown, one end of the oil seal baffle 2 is hinged to the base plate 1 , and the free end of the oil seal baffle 2 is locked on the base plate 1 by a manual latch structure.

[0045] like Figure 6 As shown, the manual latch structure of the present invention includes a manual lever 7 and a support rod 4 for guiding the sliding movement of the manual lever 7. The support rod 4 is fixed to the base plate 1. The manual lever 7 is provided with a sliding tongue that slides into a waist-shaped sliding groove 5 provided on the support rod 4. The manual lever 7 is provided with a pin 9 that inserts into a locking groove 2a provided on the oil seal baffle 2 to lock the oil seal baffle 2. A return spring 6 is provided between the manual lever 7 and the base plate 1. In its natural state, the return spring 6 forces the pin 9 into the locking groove 2a of the oil seal baffle 2. In the present invention, the manual lever 7 is manually pulled to withdraw the pin 9 from the locking groove 2a. Once fully withdrawn, the free end of the oil seal baffle 2 swings downward under its own weight, thereby releasing the seal on the engine oil port on the vehicle body and facilitating subsequent oil changes.

[0046] A coolant flow channel 106 is provided inside the base plate 1 so that external coolant can be introduced into the coolant flow channel 106 to achieve better heat dissipation.

[0047] Specifically, a cover 10 is fixed on the bottom plate 1 of the present invention at a position directly below the oil seal baffle 2. The cover 10 designed in the present invention can shield the oil seal baffle 2 and also prevent foreign objects from accidentally hitting the hand lever 7, thereby playing a good protective and shielding role.

[0048] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.

[0049] While embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions, and variations may be made to these embodiments without departing from the principles and spirit of the invention, and that the scope of the invention is defined by the appended claims and their equivalents.
