Description

Technical Field

[0001] This utility model relates to the field of engine oil filters, and in particular to an oil filter structure that is easy to disassemble and assemble. Background Technology

[0002] Currently, the main oil passage of a V-type engine is generally located in the upper middle part of the V-type engine. The design of splitting the main and auxiliary oil passages reduces the number of oil lines and manufacturing costs. The main oil passage supplies oil to the crankshaft, connecting rod and other components of the left and right cylinders of the engine. This design makes the engine oil circuit design simpler and shorter.

[0003] For engine lubrication system designs with a pre-cooling and post-filtering structure (i.e., engine oil is first cooled by the oil cooler after being pressurized, then filtered by the oil filter, and finally cooled and lubricated by the main moving parts), since the main oil passage of a V-type engine is generally designed in the upper middle part of the engine, the oil cooler and oil filter can only be placed in the upper middle part of the engine. If the oil filter is installed vertically, due to the long filter element, sufficient space needs to be reserved on the top surface of the engine to install and remove the oil filter element during engine maintenance, resulting in poor maintainability on the vehicle; since the aluminum seat is vertically upward, the oil stored in the aluminum seat cannot be automatically drained when the filter element is replaced.

[0004] The information disclosed in this background section is intended only to enhance the understanding of the overall background of this utility model and should not be construed as an admission or in any way implying that the information constitutes prior art known to those skilled in the art.

Detailed Implementation

[0022] The specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. However, it should be understood that the scope of protection of this utility model is not limited to the specific embodiments.

[0023] Unless otherwise expressly stated, throughout the specification and claims, the term "comprising" or its variations such as "including" or "comprises" shall be understood to include the stated elements or components without excluding other elements or other components.

[0024] Example 1:

[0025] An easy-to-install oil filter structure is fixed on the generator bracket 6 and connected to the oil cooler 7, such as... Figures 1 to 4 As shown, it includes:

[0026] The filter holder 1 includes a filter element mounting mechanism 11 and an oil pipe connection mechanism 12. The oil pipe connection mechanism 12 is located at one end of the filter element mounting mechanism 11. The filter element mounting mechanism 11 is a horizontally placed columnar structure, and a filter element 111 is installed inside it. A cavity 112 is formed between the filter element 111 and the filter element mounting mechanism 11. The oil pipe connection mechanism 12 has an oil inlet channel 121 and an oil return channel 122 that are not interconnected. The oil inlet channel 121 communicates with the interior of the filter element 111, and the oil return channel 122 communicates with the cavity 112. A first oil inlet mounting port 123 and a first oil return mounting port 124 are arranged side by side on the outside of the oil pipe connection mechanism 12. The first oil inlet mounting port 123 communicates with the oil inlet channel 121, and the first oil return mounting port 124 communicates with the oil return channel 124. 124 is connected to the return oil channel 122; filter cover 2, the filter cover 2 is disposed at the other end of the filter element mounting mechanism 11 and is threadedly connected to the filter element mounting mechanism 11; connecting cover 3, the connecting cover 3 is fixed on the engine cooler base of the oil cooler 7, the connecting cover 3 is provided with a second oil inlet mounting port 31 and a second oil return mounting port 32; oil inlet pipe 4, one end of the oil inlet pipe 4 is inserted into the oil pipe connecting mechanism 12 through the first oil inlet mounting port 123, and the other end is inserted into the connecting cover 3 through the second oil inlet mounting port 31; oil return pipe 5, one end of the oil return pipe 5 is inserted into the oil pipe connecting mechanism 12 through the first oil return mounting port 124, and the other end is inserted into the connecting cover 3 through the second oil return mounting port 32.

[0027] Specifically, the oil inlet channel 121 and the oil return channel 122 are parallel and staggered. The oil inlet channel 121 is directly connected to the first oil inlet mounting port 123. Since the oil return channel 122 is farther from the first oil return mounting port 124, a channel is also needed between the oil return channel 122 and the first oil return mounting port 124. The oil inlet channel 121 and the oil inlet pipe 4 form an L-shaped structure after being connected. The oil return channel 122 and the oil return pipe 5 also form an L-shaped structure after being connected. The two L-shaped structures are arranged close together. The filter cover 2 can be removed, thereby realizing the installation and removal of the filter element 111. The connecting cover 3 is used to connect and seal the oil inlet pipe 4 and the oil return pipe 5 on the oil cooler 7. The filter element mounting mechanism 11 is a cylindrical structure and is placed horizontally. As a preferred embodiment, the oil pipe connecting mechanism 12 consists of two parallel and closely attached tubular structures.

[0028] As an optional implementation, the oil inlet pipe 4 is parallel to the oil return pipe 5, and the oil inlet pipe 4 and the oil return pipe 5 are perpendicular to the oil pipe connection mechanism 12.

[0029] Specifically, the first return oil installation port 124 and the second return oil installation port 32, as well as the first oil inlet installation port 123, are vertically arranged with the oil inlet pipe 4 and the second oil inlet pipe 4, so that the oil inlet pipe 4 and the return oil pipe 5 are vertically inserted into the oil pipe connection mechanism 12 and the connection cover 3.

[0030] As an optional implementation, the bottom of the filter element mounting mechanism 11 is provided with a plurality of brackets 113, the bottom surface of the brackets 113 is flat, and the brackets 113 can be matched with the first bolt to horizontally fix the filter seat 1 on the generator bracket 6.

[0031] Specifically, the bottom surface is adapted to the top surface of the engine bracket 113, and is a flat planar structure.

[0032] As an optional implementation, there are four brackets 113, symmetrically arranged at the bottom of the filter element mounting mechanism 11.

[0033] As an optional implementation, the connecting cover 3 can be matched with the second bolt 33 to fix the oil inlet pipe 4 and the oil return pipe 5 on the machine cooler base.

[0034] Specifically, the connecting cover 3 is bolted to the machine cooler base and plugged into the oil inlet pipe 4 and the oil return pipe 5.

[0035] As an optional implementation, an O-ring 8 is provided at the connection between the oil inlet pipe 4 and the oil pipe connection mechanism 12, and at the connection between the oil inlet pipe 4 and the connection cover 3.

[0036] Specifically, at least two O-rings 8 are provided on one side for sealing.

[0037] As an optional implementation, an O-ring 8 is provided at the connection between the return oil pipe and the oil pipe connection mechanism 12, and at the connection between the return oil pipe and the connection cover 3.

[0038] Specifically, at least two O-rings 8 are provided on one side for sealing.

[0039] As an optional implementation, the bottom of the filter element mounting mechanism 11 is provided with an oil drain hole 114, which is sealed by an oil drain plug 115.

[0040] Specifically, the oil drain hole 114 is located at the bottom of the filter element mounting mechanism 11 in the vertical direction, and is used to drain the lubricating oil in the filter element mounting mechanism 11.

[0041] As an optional implementation, after the filter holder 1 is installed on the generator bracket 6 and the connecting cover 3 is installed on the oil cooler 7, the length of the oil inlet pipe 4 is less than the distance between the second oil inlet mounting port 31 and the first oil inlet mounting port 123, and greater than the distance between the connecting cover 3 and the filter holder 1; the length of the oil return pipe 5 is less than the distance between the second oil return mounting port 32 and the first oil return mounting port 124, and greater than the distance between the connecting cover 3 and the filter holder 1.

[0042] Specifically, a certain gap is left between the ends of the oil inlet pipe 4 on both sides and the top of the first oil inlet mounting port 123 and the bottom of the second oil inlet mounting port 31, and a gap is left between the ends of the oil return pipe 5 on both sides and the top of the first oil return mounting port 124 and the bottom of the second oil return mounting port 32. These gaps provide sufficient allowance for installation to eliminate any deviations in distance and angle between the mounting surfaces of the four brackets 113 of the fixed filter holder 1 and the mounting surface of the fixed connecting cover 3.

[0043] By adopting the above technical solution, this utility model provides an oil filter structure that is easy to disassemble and assemble. The filter seat 1 is horizontally assembled, which can save vertical space and allows for the horizontal disassembly and assembly of the filter element 111. The bottom of the filter seat 1 is provided with an oil drain hole 114. When disassembling the filter element 111, the lubricating oil in the filter is drained through the oil drain hole 114. The filter cover 2 is loosened, and the filter element 111 is taken out horizontally towards the front of the engine. Then, a new filter element 111 is installed, and the filter cover 2 is reinstalled. The operation is convenient and quick. The filter seat 1 is assembled on the generator bracket 6, and the connecting cover 3 is installed on the oil cooler 7. The filter seat 1 is provided with a first oil inlet mounting port 123 and a first oil return mounting port 124. The connecting cover 3 is provided with a second oil inlet mounting port 31 and a second oil return mounting port 32. The filter and the oil cooler 7 are connected by an oil inlet pipe 4 and an oil return pipe 5 that are inserted into the mounting ports. A certain gap is left between the ends of the oil inlet pipe 4 on both sides and the top of the first oil inlet mounting port 123 and the bottom of the second oil inlet mounting port 31. A gap is left between the ends of the oil return pipe 5 on both sides and the top of the first oil return mounting port 124 and the bottom of the second oil return mounting port 32. This is to provide leeway during installation to eliminate any deviation in distance and angle between the mounting surfaces of the four brackets 113 of the fixed filter holder 1 and the mounting surface of the fixed connecting cover 3.
