Description

Technical Field

[0001] This utility model relates to the field of heavy commercial vehicle frame protection technology, specifically to an integrated protection device for the engine oil pan and cooling module of a commercial vehicle. Background Technology

[0002] In the heavy-duty commercial vehicle sector, the engine oil pan and cooling module are key components of the core power system, and their structural strength and protective performance directly affect the vehicle's reliability, service life, and operating costs. Currently, the protection design for the cooling module is relatively mature, typically achieved through independently installed metal plates or composite material protective shells. These devices, by covering the bottom and sides of the cooling module, can effectively resist impacts from road debris, gravel, and potholes, reducing the risk of damage to components such as the radiator core and water pump. However, the protection of the engine oil pan has long been a technological weakness, mainly relying on simple metal baffles or open protective structures. Their protective strength and coverage are often insufficient, leading to frequent collisions, wear, and even deformation of the oil pan under complex road conditions, resulting in significant safety hazards such as oil leaks and engine overheating.

[0003] Furthermore, in actual use, enclosed guard plates are usually fixed by multiple bolts or clips. When changing the engine oil or performing other oil pan maintenance, the guard plate must be completely removed. The operation process is time-consuming and requires a high level of technical proficiency from maintenance personnel, which significantly reduces operational efficiency, especially in commercial vehicle scenarios where maintenance is frequent.

[0017] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present application.

[0018] This application provides an integrated protection device for the oil pan and cooling module of a commercial vehicle engine, which can solve the problems of insufficient protection strength and coverage for the cooling module and oil pan in the prior art, and the cumbersome maintenance of the oil pan.

[0019] Reference Figure 1 This application discloses an integrated protective device for the oil pan and cooling module of a commercial vehicle engine, including a first cooling module protective plate 1, a second cooling module protective plate 2, a side protective plate 3, and an oil pan protective plate 4. The second cooling module protective plate 2 is integrally formed with the first cooling module protective plate 1, and the connection between the second cooling module protective plate 2 and the first cooling module protective plate 1 forms an obtuse angle. During actual installation, the cooling module is located at the obtuse angle between the second cooling module protective plate 2 and the first cooling module protective plate 1, so as to provide more comprehensive protection for the cooling module from the side and bottom. The top of the side protective plate 3 is connected to the first cooling module protective plate 1 through a first connector, and the bottom of the side protective plate 3 is connected to the second cooling module protective plate 2 through a second connector, so as to protect the cooling module from the side wall of the cooling module. One end of the oil pan protection plate 4 is connected to the second cooling module protection plate 2 via a second connection, so that the oil pan protection plate 4, the second cooling module protection plate 2, and the third cooling module protection plate are integrated into one unit. This integrates the overall structure of the oil pan protection plate 4, the second cooling module protection plate 2, and the third cooling module protection plate, eliminating blind spots in protection between the two components and forming synergistic protection for the cooling module and the oil pan. The oil pan protection plate 4 has a maintenance hole 41, allowing for easy maintenance of the oil pan without disassembling the oil pan protection plate 4. This solves the problems of insufficient protection strength and coverage for the cooling module and oil pan in existing technologies, and the cumbersome maintenance of the oil pan.

[0020] In this application, two side protection plates 3 are specifically provided, which are respectively located at both ends of the width direction of the first cooling module protection plate 1 and the second cooling module protection plate 2. The maintenance hole 41 is specifically opened in the middle of the oil pan protection plate 4, and is opened corresponding to the position of the automobile drain plug and filter element, which significantly improves maintenance efficiency while protecting the oil pan.

[0021] More specifically, the first connector includes a first connecting plate 31 and an extension plate 32. The first connecting plate 31 is integrally formed with the side guard plate 3 to eliminate the structural gap between the first connecting plate 31 and the side guard plate 3, making the connection between the first connecting plate 31 and the side guard plate 3 tighter. The first connecting plate 31 extends toward the end away from the side guard plate 3 to provide a connection position for the side guard plate 3 to connect with the lower wing surface of the frame. In this embodiment, the first connecting plate 31 has multiple bolt holes to facilitate subsequent bolt connection between the lower wing surface of the frame and the side guard plate 3, thereby fixing the side guard plate 3 to the lower wing surface of the frame. The extension plate 32 is integrally formed with the first connecting plate 31, and the extension plate 32 extends downward from the first connecting plate 31 so that the extension plate 32 and the first connecting plate 31 form an inverted L-shape in the projection of the extension plate 32 and the first connecting plate 31 in the width direction of the vehicle body. The extension plate 32 is connected to the first cooling module protection plate 1 to realize the connection between the side guard plate 3 and the first cooling module protection plate 1, thereby enabling the first cooling module protection plate 1 to be connected to the lower wing surface of the frame. In this embodiment, the top of each of the two protective plates 3 is provided with an integrally formed first connecting plate 31 and an extension plate 32 to connect the first cooling module protective plate 1 to the lower wing surface of the frame from both sides, making the installation of the first cooling module protective plate 1 more stable.

[0022] The second connector includes a second connecting plate 33 and connecting bolts. The second connecting plate 33 is integrally formed with the bottom end of the side protection plate 3, and the second connecting plate 33 extends toward the second cooling module protection plate 2 so that the side protection plate 3 and the second connecting plate 33 form an L-shape on the projection of the vehicle body length direction. The second connecting plate 33 is provided with multiple bolt holes spaced apart. The connecting bolts pass through the bolt holes and the second cooling module protection plate 2 and are threadedly connected to the oil pan protection plate 4, thereby realizing the connection between the second cooling module protection plate 2 and the oil pan protection plate 4, so that the second cooling module protection plate 2 and the oil pan protection plate 4 are integrated into a structural whole, eliminating the blind spot of protection between the second cooling module protection plate 2 and the oil pan protection plate 4.

[0023] Furthermore, to protect the cooling module while accelerating its heat dissipation, multiple heat dissipation holes 11 are spaced apart on the first cooling module protective plate 1 and the second cooling module protective plate 2. In one embodiment of this application, the heat dissipation holes 11 are set as rhomboid or circular elongated holes with a diameter range of 5-15mm, which can both block splashes with a diameter greater than 15mm from impacting the cooling module and ensure the required ventilation and heat dissipation area of ​​the cooling module. In other embodiments, heat dissipation holes 11 of different shapes and with different hole diameters can be provided according to actual operating conditions.

[0024] Since fine sand and gravel can still enter the first cooling module protection plate 1 and the second cooling module protection plate 2 through the heat dissipation holes 11 during vehicle operation, the second cooling module protection plate 2, located at the bottom, is designed in a wave shape to facilitate the natural discharge of sand and gravel from the first cooling module protection plate 1 and the second cooling module protection plate 2 by gravity. The heat dissipation holes 11 on the second cooling module protection plate 2 are located at the bottom of the wave shape, so that the second cooling module protection plate 2 can have multiple inclined surfaces. This guides the fine sand and gravel to enter the heat dissipation holes 11 at the bottom along the inclined surfaces of the wave shape by their own gravity, so as to achieve natural discharge.

[0025] Furthermore, in order to further enhance the overall structural strength of the first cooling module protective plate 1 and the second cooling module protective plate 2, the first cooling module protective plate 1 and the second cooling module protective plate 2 are also provided with a number of reinforcing members 12, which are welded at intervals onto the first cooling module protective plate 1 and the second cooling module protective plate 2.

[0026] More specifically, in one embodiment of this application, protective wing 42 extends upward on both sides of the oil pan protection plate 4 to reduce the impact of sand and gravel from the side on the oil pan structure during vehicle operation. Multiple discharge holes 43 are spaced apart on the oil pan protection plate 4 to allow sand and gravel to fall along the discharge holes 43. Simultaneously, the oil pan protection plate 4 is also wavy, with the discharge holes 43 located at the bottom of the wavy structure, allowing sand and gravel to fall naturally along the inclined surface of the wavy structure. This allows the sand and gravel to fall off naturally as the vehicle moves, reducing the possibility of sand and gravel accumulating and agglomerating on the surface of the protection plate, reducing the frequency of manual cleaning, and lowering the risk of component corrosion caused by debris accumulation.

[0027] Preferably, an oil pan protection bracket 44 is provided at the end of the oil pan protection plate 4 away from the second cooling module protection plate 2. A transition bracket 45 is also provided on the oil pan protection plate 4 bracket. In the actual installation process, the transition bracket 45 is used to connect the inner side of the frame so that the oil pan protection plate 4 can be connected to the frame, and the overall connection structure is more stable. Moreover, the projection of the transition bracket 45 in the length direction of the vehicle body is S-shaped, so that a gap can be reserved between the transition bracket 45 and the lower wing surface of the frame, and the installation position is reserved for the bolts connecting the oil pan protection bracket 44 and the transition bracket 45, which facilitates the initial installation and subsequent maintenance and disassembly.
