AI Technical Summary
When the vehicle is going uphill or downhill, the oil pump has insufficient oil volume and cannot effectively draw oil, causing the vehicle to lose power. Existing technical solutions, such as increasing costs or lowering the oil tank height, cannot effectively solve this problem.
First and second baffles are installed inside the oil tank, and one-way valves are installed on the baffles. The oil pump is located in the oil suction chamber. The one-way valve controls the flow of oil, and the damping mesh plate stabilizes the flow of oil, ensuring that the oil suction chamber has sufficient oil under various slopes.
This ensures stable operation of the oil pump under various slopes, avoids insufficient oil suction, improves the oil supply stability of the oil tank, reduces costs, and maintains the regular shape of the oil tank.

[0015] Figure 1 An embodiment of the high-stability oil tank of the utility model;
[0016] Figure 2 Another embodiment of the high-stability oil tank of the utility model;
[0017] In the figure, 1 is an oil tank body, 11 is a front cavity, 12 is an oil suction cavity, 13 is a rear cavity, 2 is an oil pump, 3 is a first baffle, 4 is a second baffle, 5 is a first one-way valve, 6 is a second one-way valve, and 7 is a damping mesh plate. DETAILED DESCRIPTION
[0018] The application will be further described below in conjunction with specific embodiments. Obviously, the described embodiments are only part of the embodiments of the application, rather than all the embodiments. Based on the embodiments in the application, all other embodiments obtained by those skilled in the art without creative changes belong to the protection scope of the application.
[0019] As Figure 1As shown in the utility model provides a kind of high stability oil tank, including oil tank body 1 and oil pump 2, the oil tank body 1 inside is provided with first baffle 3 and second baffle 4, the first baffle 3 and second baffle 4 the cavity of the oil tank body 1 is divided into front cavity 11, oil suction cavity 12 and rear cavity 13, the oil pump 2 is arranged in the oil suction cavity 12, first check valve 5 is provided on the first baffle 3, second check valve 6 is provided on the second baffle 4, the first check valve 5 is configured to make oil liquid enter the oil suction cavity 12 from the front cavity 11, the second check valve 6 is configured to make oil liquid enter the oil suction cavity 12 from the rear cavity 13.
[0020] When the vehicle is uphill, the oil tank will be tilted, and the oil flows to the rear of the oil tank. Because the first baffle 3 and the second baffle 4 and the first check valve 5 and the second check valve 6 are provided, at this time, the oil in the front cavity 11 flows to the oil suction cavity 12 through the first check valve 5 of the first baffle 3, and the oil in the oil suction cavity 12 cannot flow to the rear cavity 13 through the second check valve 6 of the second baffle 4, thus ensuring the amount of oil in the oil suction cavity 12 and ensuring the stable operation of the oil pump 2. Similarly, when the vehicle is downhill, the oil tank will also be tilted, and at this time, the amount of oil in the oil suction cavity 12 can also be ensured, and the stable operation of the oil pump 2 can be ensured. The oil suction cavity 12 can be arranged in the middle, rear or front of the oil tank body 1 according to actual needs.
[0021] To further improve the stability of oil supply, in some embodiments, the number of first check valves 5 is at least two, and the number of second check valves 6 is at least two. As shown in the figure, the number of first check valves 5 and second check valves 6 is two. In the case of damage or failure of one of the first check valves 5 or second check valves 6, the other first check valve 5 or second check valve 6 serves as a backup, and normal operation can still be maintained.
[0022] To ensure that the oil in the front cavity 11 and the rear cavity 13 can flow smoothly into the oil suction cavity 12, in some embodiments, the first check valve 5 is arranged near the bottom of the first baffle 3, and the second check valve 6 is arranged near the bottom of the second baffle 4.
[0023] As Figure 2 shown, as a further improvement of the above embodiments, in some embodiments, a damping mesh plate 7 is arranged in the oil suction cavity 12. The damping mesh plate 7 can increase the resistance of the oil flow in the oil suction cavity 12, improve the stability, and avoid the oil in the oil suction cavity 12 fluctuating too much under the conditions of uphill, downhill or bumpy road, which can adversely affect oil supply.
[0024] Specifically, as Figure 2As shown, the first partition 3 and the oil pump 2 and the second partition 4 and the oil pump 2 are both provided with the damping mesh plate 7, wherein the damping mesh plate 7 is in the form of a plate.
[0025] In order to further avoid excessive fluctuation of the oil, in some embodiments, the first partition 3 and the oil pump 2 and the second partition 4 and the oil pump 2 are both provided with at least two layers of the damping mesh plate 7 (only one layer of the damping mesh plate 7 is shown in the figure).
[0026] As an alternative to the above-mentioned plate-shaped damping mesh plate 7, in some embodiments, the damping mesh plate 7 is in the form of a ring and encloses the outside of the oil pump 2 (not shown in the figure).
[0027] In order to further avoid excessive fluctuation of the oil, in some embodiments, there are at least two layers of the ring-shaped damping mesh plate 7.
[0028] Although the present disclosure is disclosed as above, the protection scope of the present disclosure is not limited to this. Those skilled in the art can make various changes and modifications without departing from the spirit and scope of the present disclosure, and these changes and modifications shall fall within the protection scope of the present disclosure.
