Description

Technical Field

[0001] This invention relates to the field of separation device technology, and in particular to an automotive oil-gas separator with a pressure relief valve and its assembly method. Background Technology

[0002] Oil-gas separators can be applied in the engine compartment of automobiles. Their principle is to use the negative pressure in the intake manifold to draw in blow-by gas formed in the crankcase and lead it to the combustion chamber to re-participate in combustion, achieving the effects of environmental protection and high utilization rate. Its main function is to reduce the oil residue sticking to the intake pipe by filtering the engine oil, and to prevent blow-by gas from directly entering the intake pipe and causing carbon deposits to form.

[0003] For example, Chinese Patent Publication No. CN211799563U discloses an oil-gas separator for automobiles, comprising a housing, a filter element installed inside the housing, and a mounting base covering the housing. The mounting base has an air inlet and an air outlet. A cover plate is fixedly connected to the upper end of the housing, and a connection hole corresponding to the interior of the filter element is opened at the center of the cover plate. The air outlet comprises an installation tube integrally formed with and passing through the mounting base, and an exhaust head fixedly connected to the upper end of the installation tube. The lower end of the installation tube extends into the housing through the mounting base, and the lower end of the installation tube is threadedly connected to the connection hole. The air outlet is integrally formed with the mounting base, effectively strengthening the connection strength and sealing performance. Furthermore, the integral forming design reduces subsequent installation operations, minimizes process errors, and improves the overall product quality.

[0004] When assembling the housing with the mounting base, the operator needs to reach into the engine compartment and rotate the housing multiple times. Before rotating, the housing and mounting base need to be aligned so that their threads correspond. Furthermore, during later maintenance, the housing needs to be rotated multiple times in the opposite direction to disassemble it, which increases the workload of the operator and results in low work efficiency.

[0005] Therefore, it is necessary to provide an automotive oil-gas separator with a pressure relief valve and its assembly method to solve the above-mentioned technical problems. Summary of the Invention

[0006] The purpose of this invention is to provide an automotive oil-gas separator with a pressure relief valve and its assembly method, so as to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, an automotive oil-gas separator with a pressure relief valve is designed that eliminates the need to repeatedly rotate the separator cylinder by reaching into the engine compartment, thereby facilitating the quick assembly and disassembly of the separator cylinder.

[0008] Based on the above ideas, the present invention provides the following technical solution: a vehicle oil-gas separator with a pressure relief valve, comprising a mounting base, an oil-gas separator module for realizing oil-gas separation is provided on the mounting base, a separator cylinder adapted to the oil-gas separator module is threadedly fitted to the bottom of the mounting base, a pressure relief valve adapted to the oil-gas separator module is provided on the top of the mounting base, and an adjustment component is provided between the mounting base and the separator cylinder, the adjustment component is provided with a positioning component that abuts against the bottom of the separator cylinder; rotating the adjustment component can cause the separator cylinder to have an upward tendency through the positioning component, and the adjustment component can drive the separator cylinder to rotate synchronously when rotating.

[0009] As a further embodiment of the present invention: the adjustment assembly includes a central shaft rotatably mounted on the mounting base and a second gear fixedly mounted on the outer surface of the separation cylinder. A knob and a first gear that are connected to the second gear are fixedly mounted on the outer surface of the central shaft. A partition is threadedly fitted on the outer surface of the central shaft and below the first gear. A telescopic rod is fixedly mounted between the partition and the bottom of the mounting base.

[0010] As a further embodiment of the present invention: the partition is limited to vertically raising and lowering along the central axis by a telescopic rod, and the knob is located on the top of the mounting base.

[0011] As a further aspect of the present invention: the thickness of the second gear is greater than that of the first gear, so that when the separating cylinder drives the second gear to move up and down, it can always maintain a transmission state with the first gear.

[0012] As a further embodiment of the present invention: the positioning assembly includes a support plate slidably mounted on the outer surface of the central shaft and the telescopic rod, the top surface of the support plate being in contact with the bottom surface of the separation cylinder, and a plurality of springs being fixedly mounted on the bottom surface of the support plate to abut against the partition plate.

[0013] As a further aspect of the present invention: the pallet is limited to vertically rising and falling along the central axis by a telescopic rod and a central axis, and the spring causes the pallet to have a tendency to rise along the central axis.

[0014] As a further aspect of the present invention: the top surface of the tray is provided with a groove for placing the separating cylinder, and the groove corresponds to the center of the thread line of the mounting base; when the separating cylinder is placed in the groove, the thread of the separating cylinder can correspond vertically to the thread of the mounting base.

[0015] As a further aspect of the present invention: the second gear includes a third gear that is drivenly connected to the first gear and a support rod that is fixedly installed at the bottom of the mounting base. The bottom surface of the third gear and the outer surface of the separating cylinder are connected by a belt drive. The support rod is inserted into the center of the third gear to achieve positioning.

[0016] As a further aspect of the present invention: the thickness of the third gear is greater than that of the first gear, and the diameter of the third gear is smaller than that of the first gear.

[0017] This invention also provides the following technical solution: an assembly method for an automotive oil-gas separator, comprising the following steps: S1. Place the separator cylinder onto the positioning assembly. At this time, the separator cylinder is located between the positioning assembly and the mounting base. S2. The rotation adjustment component, through the positioning component, can make the separation cylinder have an upward trend, and when the adjustment component rotates, it can drive the separation cylinder to rotate synchronously, so that the thread of the separation cylinder corresponds to the thread of the mounting base, thereby realizing threaded assembly.

[0018] Compared with the prior art, the beneficial effects of the present invention are as follows: through the cooperation between the mounting base, the separator cylinder, the adjustment component, and the positioning component, once the mounting base is fixed to the engine compartment, the separator cylinder and the mounting base can be quickly disassembled and assembled simply by rotating the adjustment component. Moreover, the operating position is located at the top of the mounting base, so the operator does not need to reach into the engine compartment to rotate the separator cylinder multiple times, nor does the operator need to align the threads of the separator cylinder and the mounting base. It is also not limited by the complex installation environment inside the engine compartment, which can effectively reduce the disassembly and assembly burden of the operator and effectively improve the disassembly and assembly efficiency of the separator cylinder.

[0019] When the separator cartridge is released from the mounting bracket, it is effectively supported by the positioning components and will not fall off directly. This prevents improper gripping by workers and avoids spillage of grease from the separator cartridge into the engine compartment, thus maintaining the overall cleanliness of the engine compartment. The overall structure is simple and easy to use; the vehicle owner can also perform the corresponding operations by opening the compartment cover, effectively improving the overall user experience and enhancing practicality.

Detailed Implementation

[0022] Example 1: Please see Figures 1 to 5 This invention provides an automotive oil-gas separator with a pressure relief valve 6, which is mainly used to achieve quick assembly and disassembly of the separator cylinder 3 and the mounting base 1 and is applicable to relatively complex installation environments. The device includes a mounting base 1, which is fixedly installed in the engine compartment by bolts. An oil-gas separator module 2 for achieving oil-gas separation is provided on the mounting base 1, and a separator cylinder 3 adapted to the oil-gas separator module 2 is threadedly assembled to the bottom of the mounting base 1.

[0023] After the separator cylinder 3 and the mounting base 1 are screwed in and locked, the grease separated by the oil-gas separation module 2 can be directly collected in the separator cylinder 3, while the gas is then guided into the air intake pipe. Both the oil-gas separation module 2 and the mounting base 1 are existing, mature technologies and will not be described in detail here.

[0024] Furthermore, an adjustment component 4 is provided between the mounting base 1 and the separator cylinder 3, and a positioning component 5 is provided on the adjustment component 4 to abut against the bottom of the separator cylinder 3. When the mounting base 1 is assembled onto the engine compartment, rotating the adjustment component 4 through the positioning component 5 ensures that the separator cylinder 3 is always in an upward trend, and the rotation of the adjustment component 4 can drive the separator cylinder 3 to rotate synchronously, thereby allowing the separator cylinder 3 to automatically form a threaded assembly with the mounting base 1; at this time, it is only necessary to place the separator cylinder 3 on the positioning component 5, and then rotate the adjustment component 4 above the mounting base 1, without the operator needing to reach their hands into the deeper parts of the engine compartment.

[0025] Reference Figures 2 to 4In this embodiment, preferably, the adjusting component 4 includes a central shaft 401 rotatably mounted on the mounting base 1 and a second gear 405 fixedly mounted on the outer surface of the separating cylinder 3. A knob 404 and a first gear 402 that are connected to the second gear 405 are fixedly mounted on the outer surface of the central shaft 401. A partition 403 is threadedly mounted on the outer surface of the central shaft 401 and below the first gear 402. A telescopic rod 406 is fixedly mounted between the partition 403 and the bottom of the mounting base 1.

[0026] In the above structure, the telescopic rod 406 can limit the partition 403 so that it can only move vertically when the central shaft 401 rotates, and the telescopic rod 406 can be staggered with the first gear 402 and the second gear 405 to avoid interfering with the rotation of the first gear 402 and the second gear 405; while the knob 404 is located on the top of the mounting base 1 for the operator to rotate accordingly.

[0027] The thickness of the second gear 405 is greater than that of the first gear 402, so that the separating cylinder 3 can always maintain a transmission state with the first gear 402 when it drives the second gear 405 to move up and down.

[0028] Reference Figures 2 to 5 In this embodiment, preferably, the positioning component 5 includes a support plate 501 that is slidably mounted on the outer surface of the central shaft 401 and the telescopic rod 406. The top surface of the support plate 501 is in contact with the bottom surface of the separation cylinder 3. A plurality of springs 502 are fixedly mounted on the bottom surface of the support plate 501 and abut against the top surface of the partition plate 403. Under the action of the springs 502, the support plate 501 has a tendency to rise along the central shaft 401, thereby pushing the separation cylinder 3 to have a tendency to move closer to the mounting base 1.

[0029] Reference Figure 5 In this embodiment, preferably, the top of the mounting base 1 is provided with a pressure relief valve 6 adapted to the oil-gas separation module 2. When the overall pressure of the device is too high, the gas can be released from the pressure relief valve 6. The pressure relief valve 6 is an existing mature technology and will not be described in detail here. Its structural size can be selected to adapt to different mounting bases 1 and vehicle models.

[0030] In use, firstly, the mounting base 1 is fixedly installed into the engine compartment using bolts. Then, the support plate 501 is pressed down to place the separator cylinder 3 between the support plate 501 and the mounting base 1, ensuring that the threads of the separator cylinder 3 correspond to those of the mounting base 1. Next, the knob 404 is rotated to drive the central shaft 401 to rotate, causing the partition plate 403 to rise vertically via the telescopic rod 406. The partition plate 403, through the spring 502 and the support plate 501, further raises the separator cylinder 3, effectively aligning it with the threads of the mounting base 1. When the central shaft 401 rotates, it drives the separator cylinder 3 to rotate synchronously via the first gear 402 and the second gear 405. Combined with the upward movement of the mounting base 1 by the support plate 501, this allows the threads of the separator cylinder 3 to quickly align with the threads of the mounting base 1, ultimately enabling the separator cylinder 3 to be quickly assembled onto the mounting base 1.

[0031] In summary, through the cooperation of structures such as the central shaft 401, the first gear 402, the partition plate 403, and the support plate 501, once the mounting base 1 is fixed to the engine compartment, simply turning the knob 404 allows for quick assembly and disassembly of the separator cylinder 3 from the mounting base 1. Furthermore, the operating position is located at the top of the mounting base 1, eliminating the need for operators to reach deep into the engine compartment to continuously rotate the separator cylinder 3 multiple times, or to align the threads of the separator cylinder 3 with the mounting base 1. It is also not limited by the complex installation environment inside the engine compartment, effectively reducing the workload for operators and significantly improving the efficiency of the separator cylinder 3 assembly and disassembly.

[0032] When the separator cylinder 3 is released from the mounting base 1, it can be effectively supported by the support plate 501 and will not fall off directly. This avoids the possibility of the operator accidentally failing to grip it properly and prevents grease inside the separator cylinder 3 from spilling into the engine compartment and causing contamination, thus helping to maintain the overall cleanliness of the engine compartment. The overall structure is simple and easy to use. The vehicle owner can also perform the corresponding operations by opening the compartment cover, effectively improving the overall user experience and making it more practical.

[0033] Example 2: Please see Figures 1 to 7 Based on Embodiment 1, considering that the separating cylinder 3 is simply placed on the tray 501, it may be offset along the top surface of the tray 501, which will affect the correspondence between the separating cylinder 3 and the thread on the mounting base 1 after placement, and also affect the subsequent quick assembly of the separating cylinder 3 and the mounting base 1.

[0034] Therefore, the tray 501 is improved: the top surface of the tray 501 is provided with a groove 503 for the placement of the separation cylinder 3. The groove 503 is adapted to the size of the separation cylinder 3, and the groove 503 corresponds to the center of the thread line of the mounting base 1, so that when the separation cylinder 3 is placed in the groove 503, it can automatically correspond to the thread of the mounting base 1.

[0035] Furthermore, a soft padding layer (not shown in the figure) can be fixedly installed inside the groove 503. When the car bounces up and down during driving, the spring 502 causes the support plate 501 to reciprocate up and down. At this time, the support plate 501 has the function of reciprocatingly striking the separator 3. During the reciprocating process, the service life of the filter element in the oil-gas separation module 2 can be extended, ensuring the overall performance of the device. The soft padding layer can effectively reduce damage to the surface of the separator 3, ensuring the overall service life of the device. Of course, the above effects can also be achieved in Embodiment 1, but it has not been described in detail.

[0036] In use, the separation cylinder 3 and the mounting base 1 can be quickly assembled and disassembled by rotating the knob 404 through the structure of the central shaft 401, the first gear 402, and the support plate 501. The rotation position is located at the top of the mounting base 1 for easy operation. The working process and effect of this part are the same as in Embodiment 1, and will not be repeated here. The difference is that after pressing down the support plate 501, the separation cylinder 3 can be placed in the groove 503. Then, rotating the knob 404 through the central shaft 401, the partition plate 403, and the support plate 501 can make the separation cylinder 3 have an upward tendency, and can also drive the separation cylinder 3 to rotate and quickly assemble it onto the mounting base 1. When the car is driving on a bumpy road, the support plate 501, in conjunction with the spring 502, can perform a reciprocating up and down movement, providing a knocking vibration effect to the separation cylinder 3 and the whole device.

[0037] Compared to Embodiment 1, the combination of the support plate 501, spring 502, groove 503, and padding layer ensures that when the separator cylinder 3 is placed in the groove 503, it aligns vertically with the threads of the mounting base 1. This prevents the separator cylinder 3 from shifting and affecting the thread insertion, ensuring quick assembly and disassembly of the separator cylinder 3 and the mounting base 1. Furthermore, the support plate 501 and spring 502 provide a tapping and vibration effect, which can extend the service life of the filter element in the oil-gas separation module 2, ensuring the overall performance of the device. The overall design, combined with the support plate 501, also serves as a reminder that the separator cylinder 3 has been placed in the groove 503, further enhancing the overall user experience and making the device more versatile.

[0038] Example 3: Please see Figures 1 to 10 Based on Embodiment 2, considering the limited installation environment of the mounting base 1 in the engine compartment, the diameter of the second gear 405 on the separator cylinder 3 is usually larger than that of the first gear 402. This means that the central shaft 401 needs to drive the first gear 402 to rotate many times before the separator cylinder 3 can be rotated relative to the mounting base 1 into position. This also means that it takes many rotations to complete the disassembly, which means that the disassembly and assembly efficiency still needs to be improved.

[0039] Therefore, the second gear 405 is improved: The second gear 405 now includes a third gear 4051 that is connected to the first gear 402 and a support rod 7 fixedly installed at the bottom of the mounting base 1. The third gear 4051 has the same thickness as the second gear 405, and its diameter is smaller than that of the first gear 402. The bottom surface of the third gear 4051 is connected to the outer surface of the separating cylinder 3 via a belt drive 4052. When the first gear 402 drives the third gear 4051 to rotate, the separating cylinder 3 rotates accordingly via the belt drive 4052. Of course, the diameter of the pulley of the belt drive 4052 can be adjusted according to specific requirements.

[0040] In the above structure, the third gear 4051 is hollow. When the pressing plate 501 causes the separating cylinder 3 to be placed into the groove 503, the support rod 7 is inserted into the third gear 4051. At this time, the support rod 7 can provide a positioning effect for the third gear 4051, and the third gear 4051 can slide up and down based on the support rod 7.

[0041] As a further improvement to this embodiment, the installation position of the third gear 4051 can be adjusted so that it is no longer located in the exact middle of the separator cylinder 3 and the first gear 402, but is set at an angle. At this time, the separator cylinder 3 can be relatively close to the central shaft 401, and a pulley with a larger diameter can be used. Based on this, the overall space occupied by the device can be reduced accordingly, and more engine compartments can be used for assembly.

[0042] In use, the separation cylinder 3 and the mounting base 1 can be quickly disassembled and assembled by rotating the knob 404 through the structure of the central shaft 401, the first gear 402, and the support plate 501. The rotation position is located at the top of the mounting base 1 for easy operation. Through the structure of the support plate 501, the spring 502, and the groove 503, when the separation cylinder 3 is placed in the groove 503, it corresponds vertically with the thread of the mounting base 1, ensuring quick disassembly and assembly of the separation cylinder 3 and the mounting base 1. The working process and effect of this part are the same as in Embodiment 2, and will not be repeated here. The difference is that when the separation cylinder 3 is placed in the groove 503, the third gear 4051 and the first gear 402 form a transmission, and the support rod 7 is inserted into the third gear 4051. When the knob 404 is rotated subsequently, the separation cylinder 3 can still be driven to rotate through the central shaft 401, the first gear 402, the third gear 4051, and the belt drive 4052. Furthermore, the separation cylinder 3 still has an upward trend through the central shaft 401, the partition plate 403, and the support plate 501.

[0043] Compared to Embodiment 2, the cooperation of the first gear 402, the third gear 4051, the support rod 7, and the belt drive 4052, while ensuring effective assembly between the separating cylinder 3 and the mounting base 1, reduces the number of rotations of the central shaft 401 driven by the knob 404. This further improves the assembly and disassembly efficiency of the separating cylinder 3 and reduces the workload of operators. The overall design, combined with the placement of the third gear 4051, does not affect the placement of the separating cylinder 3. After the separating cylinder 3 is placed in the groove 503, the support plate 501 causes the separating cylinder 3 to rise, allowing the support rod 7 to automatically insert into the third gear 4051 without excessive operator intervention, thus meeting more practical needs.

[0044] Example 4: Please see Figures 1 to 10 This invention provides an assembly method for an automotive oil-gas separator. This embodiment adopts any one of embodiments one to three, and therefore also has corresponding beneficial effects.

[0045] Specifically, first, the separating cylinder 3 is placed on the positioning component 5, and then the adjusting component 4 is rotated. Through the cooperation of the adjusting component 4 and the positioning component 5, the separating cylinder 3 can have an upward trend, and the adjusting component 4 can drive the separating cylinder 3 to rotate synchronously, so that the thread of the separating cylinder 3 can quickly correspond with the thread of the mounting base 1, and the two can quickly achieve thread assembly.
