Description

Technical Field

[0001] The utility model relates to the technical field of oil tanks, in particular to a double-cavity oil tank. Background Art

[0002] The automobile fuel tank, as an important component of the automobile, is mainly used to store the fuel required by the vehicle and ensure that the fuel can be stably and safely supplied to the engine during driving.

[0003] In order to start the engine under ultra-low temperature conditions, a fuel type different from ordinary fuel is required, so an additional fuel tank is required. In this case, two separate fuel tanks are usually set up for storage, but the fuel tanks take up a large space, which is not conducive to the installation of other components.

[0004] At the same time, when refueling, it is necessary to remove the plug of the fuel tank filling port. However, during the operation of the car, the fuel in the fuel tank is in an active state and is easily splashed onto the plug. Therefore, it is easy for the staff to dirty their hands when removing the plug. After the plug is removed, it is easy to contact the car body with the car body, which also causes the car body to be dirty, causing inconvenience to the user. Utility Model Content

[0005] The purpose of the utility model is to provide a double-chamber fuel tank to solve the following technical problems:

[0006] How to prevent dirty hands when removing and placing the plug on the fuel tank during refueling.

[0007] The purpose of the utility model can be achieved through the following technical solutions:

[0008] A double-chamber oil tank comprises an oil tank body, wherein a partition is arranged inside the oil tank body to separate the inside of the oil tank body into two independent chambers, and the chamber walls of the two independent chambers are both provided with oil inlets, and each oil inlet is provided with a matching plug to seal the oil inlet;

[0009] Movable plates are hinged on two inner walls opposite to one end of the oil inlet near the tank body, the ends of the two movable plates are butt-jointed and closed, and elastic members are connected between one side of the two movable plates near the tank body and the tank body, and plug plates corresponding to the two movable plates are connected at two opposite ends of the inner side of the plug, and the ends of the plug plates are pressed against the hinged ends of the movable plates.

[0010] As a further solution of the utility model: the cross section of the oil inlet is square.

[0011] As a further solution of the utility model: two limit plates are installed on the inner wall of the oil inlet, and the two limit plates are respectively located below one side where the two movable plates are hinged to the oil inlet.

[0012] As a further solution of the utility model: the elastic member is a spring.

[0013] As a further solution of the utility model: a groove is provided at the center of the outer side of the plug, and a convex rib is provided in the groove.

[0014] As a further solution of the utility model: the outer sides of the ends of the two movable plates close to each other are both provided with slopes, so as to form an insertion gap between the movable plates and the inner wall of the oil inlet when the movable plates bounce onto the inner wall of the oil inlet.

[0015] As a further solution of the utility model: a magnetic block is disposed at one end of the two movable plates close to each other, and the magnetism of the two magnetic blocks is opposite.

[0016] Beneficial effects of the utility model:

[0017] (1) When the fuel tank is used, different fuels can be stored in two independent chambers. Compared with using two fuel tanks, it not only saves installation space but also saves manufacturing costs.

[0018] (2) When refueling, when the plug is removed from the fuel inlet, the plug will bring out the plug plate, and the two movable plates will bounce up to the inner wall of the fuel inlet under the action of elastic force. At this time, the fuel inlet is in a fully open state and refueling can be carried out. After refueling, the plug is inserted again. The two plug plates on the lower side of the plug slide downward through the insertion gap formed by the slope of the movable plate, thereby driving the two movable plates to flip downward to a closed state of horizontal docking. During the movement of the car, even if the fuel in the main body of the fuel tank splashes, it will be blocked by the movable plate to prevent splashing onto the plug, so that the plug is always kept clean. Therefore, when refueling, the plug needs to be removed without dirty hands, and the plug will not carry fuel to other parts of the car body, making refueling more convenient and quick.

[0026] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0027] See also Figure 1 As shown, the utility model is a double-chamber oil tank, including an oil tank body 100. The oil tank body 100 is a horizontal cylindrical shape. There is no restriction on the material thereof, as long as it meets the oil storage demand. For example, in the embodiment of the utility model, the oil tank body 100 is made of aluminum alloy, which has high strength and corrosion resistance. A partition 200 is welded inside the oil tank body 100. The partition 200 is vertically welded to the inner wall of the oil tank body 100. On the one hand, the overall rigidity of the oil tank body 100 can be enhanced, and on the other hand, the oil tank body 100 can be divided into two independent cavities, which can be used to store different types of fuel. Compared with the use of two oil tanks, it not only saves installation space, but also saves manufacturing costs. Fuel type labels are affixed to the outside of the two independent cavities of the oil tank body 100 to distinguish the type of fuel in each independent cavity.

[0028] See also Figure 2-3 , oil inlets 300 are respectively arranged on the upper sides of the cavity walls of the two independent cavities for filling oil into the cavities, and oil outlets are respectively arranged at the bottom for discharging oil; the cross-section of the oil inlet 300 is set to be square, and a detachable plug 400 is arranged on the oil inlet 300, the inner side of the plug 400 is consistent with the outer opening shape of the oil inlet 300, and can be plugged into the outer port of the oil inlet 300 to close the oil inlet 300; a groove 402 is provided at the center of the outer side of the plug 400, and a convex rib 403 is provided in the groove 402, and the plug 400 can be taken and placed through the convex rib 403, which is more convenient and labor-saving; plug plates 401 are vertically connected to the left and right sides of the lower side of the plug 400.

[0029] Movable plates 500 are hinged at the lower ends of the inner walls on the left and right sides of the oil inlet 300, and the two movable plates 500 can be flipped up and down around the hinge axis; limit plates 700 connected to the inner walls of the oil inlet 300 are respectively installed below the hinges of the two movable plates 500. When the two movable plates 500 are rotated to a horizontal state, the two limit plates 700 can limit the movable plates 500 to prevent the movable plates 500 from continuing to flip downward, thereby maintaining a horizontal state. At this time, the ends of the two limit plates 700 are butted and closed to close the oil inlet 300; in order to make the two movable plates 500 dock more smoothly, magnetic blocks 501 with opposite magnetic poles are respectively installed at the ends of the two movable plates 500. When the two movable plates 500 move to a horizontal state, they will quickly dock and close under the attraction of the magnetic blocks 501, and will not be easily misaligned.

[0030] See also Figure 4-5 , elastic members are connected between the lower sides of the two movable plates 500 and the oil tank body 100, and the specific form of the elastic members is not limited. For example, in the embodiment of the utility model, the elastic member is a spring 600, and the two ends of the spring 600 are respectively fixedly connected to the lower side of the movable plate 500 and the inner wall of the oil tank body 100. Therefore, when the plug 400 is not installed, under the elastic force of the spring 600, the movable plate 500 will be flipped to fit the inner wall of the oil inlet 300 under the elastic force; the upper outer ends of the two movable plates 500 are respectively set Slope, so when the movable plate 500 rotates to fit with the inner wall of the oil inlet 300, the upper end of the movable plate 500 will not contact the inner wall of the oil inlet 300 due to the existence of the slope, thereby forming an insertion gap. At this time, when the plug 400 is inserted, the two plug plates 401 on the lower side of the plug 400 slide downward through the insertion gap, thereby driving the two movable plates 500 to flip downward to a closed state of horizontal docking. Once the plug 400 is taken out and the plug plates 401 are taken out, the two movable plates 500 will bounce up to the inner wall of the oil inlet 300 under the action of elastic force.

[0031] The working principle of this utility model:

[0032] When the fuel tank is used, different fuels can be stored in two independent cavities, which not only saves installation space but also saves manufacturing cost compared to using two fuel tanks; when the plug 400 is removed from the fuel inlet 300, the plug 400 will bring out the plug plate 401, and the two movable plates 500 will bounce up to the inner wall of the fuel inlet 300 under the action of elastic force, and the fuel inlet 300 is in a fully open state at this time, and refueling can be carried out. After refueling, the plug 400 is inserted again, and the two plug plates 401 on the lower side of the plug 400 are opened. The plug 400 is prevented from splashing onto the plug 400 by sliding downward through the slot formed by the slope of the movable plate 500, thereby driving the two movable plates 500 to flip downward to a closed state of horizontal docking. During the movement of the automobile, even if the fuel in the fuel tank body 100 splashes, it will be blocked by the movable plate 500 to prevent splashing onto the plug 400, so that the plug 400 always remains clean. Therefore, when refueling, the plug 400 needs to be removed without dirtying hands, and the plug 400 will not carry fuel to other parts of the vehicle body, which makes refueling more convenient and quick.
