Description

Technical Field

[0001] This application relates to the technical field of mobile equipment, and particularly relates to a fuel tank structure and a mobile equipment. Background Art

[0002] Traditional fuel tank structures are calibrated based on a horizontal ground, and are mostly rectangular in shape. The bottom surface has a large and irregular flat surface. Usually, a fixed suction pipe is placed in the middle of the bottom of the fuel tank, close to the bottom of the tank to absorb fuel to the maximum extent.

[0003] However, the driving conditions of vehicles are complex and the roads are not flat. The fuel tank is often in an inclined state. In this case, the liquid level of the oil changes greatly. At this time, the suction pipe may experience air suction, resulting in insufficient engine fuel supply, affecting power, driving, and even safety.

[0004] At the same time, it is found in actual use that when the vehicle is driving on complex roads such as slopes and the fuel is not very sufficient, the inclination of the fuel tank causes the fuel pump to fail to suck oil and the vehicle stalls, shortening the actual driving range and affecting the normal use of the vehicle. This is especially obvious for off-road vehicles. Summary of the Utility Model

[0005] The embodiments of this application provide a fuel tank structure and a mobile equipment to solve the problem that when the existing vehicle is driving on complex roads such as slopes, the inclination of the fuel tank causes the fuel pump to fail to suck oil and the vehicle stalls, shortening the actual driving range and affecting the normal use of the vehicle.

[0010] Wherein, the oil suction pipe portion is kept arranged along the gravity direction under the action of the gravity component.

[0011] In an embodiment, the inner wall of the receiving cavity is spherical, spherical crown-shaped or elliptical.

[0012] In an embodiment, the oil suction pipe portion is provided with an oil inlet;

[0015] Wherein, the oil inlet is located in the installation through-hole and is arranged towards the filter element.

[0016] In one embodiment, the installation through-hole is a stepped hole, which includes a first installation hole and a second installation hole. The aperture of the first installation hole is larger than that of the second installation hole. Wherein, the first installation hole is used for installing the filter element, and the second installation hole is used for installing the oil suction pipe portion;

[0017] The filter element and the oil inlet are arranged at intervals, and an oil storage space is formed at the part of the installation through-hole between the filter element and the oil inlet.

[0018] In one embodiment, an anti-corrosion rubber layer is provided on the outer wall of the body or an anti-corrosion rubber sleeve is sleeved on the outer wall of the body.

[0023] In a second aspect, the present application provides a mobile device, including the fuel tank structure as described in any one of the above embodiments.

[0024] The fuel tank structure provided by the embodiments of the present application includes a housing, an oil suction pipe fitting and a gravity component. Wherein, the housing is provided with an accommodation cavity, and at least the inner wall of the bottom of the accommodation cavity is an arc surface; the oil suction pipe fitting includes a connecting portion and an oil suction pipe portion for sucking fuel in the accommodation cavity, which are connected to each other.

[0025] It can be understood that in the embodiments of the present application, since at least the inner wall of the bottom of the accommodating cavity is set as an arc surface, when the vehicle is driving on a complex road surface such as a slope, the fuel in the fuel tank structure will flow along the inner wall of the arc surface, making the fuel easier to flow and gather at the inclined part of the accommodating cavity. At the same time, since the gravity component is arranged in the accommodating cavity and the gravity component is also connected to the oil suction pipe fitting, when the fuel tank structure is inclined, the oil suction pipe part can be moved towards the direction close to the liquid level of the oil by the gravity component, so that the oil suction pipe part can always stay at the inclined part in the accommodating cavity and the oil suction pipe part is always immersed in the fuel, which is convenient for oil suction. This can avoid the situation that when the inner wall of the existing accommodating cavity is a plane and the fuel tank is inclined, the fuel flows away, resulting in no oil at some plane parts, so that the fuel pump fails to suck oil and the flameout phenomenon occurs. In addition, since the connecting part is connected to the shell and the oil suction pipe part at the same time, the position of the oil suction part can be fixed through the connecting part, so as to avoid the problem that the oil suction pipe part deviates and cannot suck oil when the vehicle is driving on a complex road surface such as a slope. At the same time, it can also avoid the situation that the oil suction pipe part collides with the inner wall of the shell to generate noise. BRIEF DESCRIPTION OF THE DRAWINGS

[0039] Next, the technical solutions in the embodiments of the present application will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative efforts belong to the scope of protection of the present application.

[0040] Based on the above technical problems, an embodiment of the present application provides a fuel tank structure 100, as Figure 1 shown. In this embodiment, the fuel tank structure 100 includes a housing 110, an oil suction pipe fitting 120, and a gravity assembly 130. Among them, the housing 110 is provided with a receiving cavity 111, and at least the inner wall of the bottom of the receiving cavity 111 is an arc surface; the oil suction pipe fitting 120 includes a connecting portion 121 and an oil suction pipe portion 122 for sucking fuel in the receiving cavity 111. The connecting portion 121 is connected to the housing 110, and the oil suction pipe portion 122 is received in the receiving cavity 111; the gravity assembly 130 is also disposed in the receiving cavity 111, and the gravity assembly 130 is connected to the oil suction pipe portion 122; at the same time, the oil suction pipe portion 122 is kept disposed along the gravity direction under the action of the gravity assembly 130.

[0041] An oil pump 150 is further connected to the oil suction pipe fitting 120. Specifically, the oil suction pipe fitting 120 further includes a fuel supply pipe portion 123. The fuel supply pipe portion 123 is integrally formed with the oil suction pipe portion 122, or is connected and communicated with each other. The connecting portion 121 is disposed between the fuel supply pipe portion 123 and the oil suction pipe portion 122. The oil pump 150 is fixed on the housing 110 and is connected to the fuel supply pipe portion 123. When the oil pump 150 is working, it sucks oil through the oil suction pipe portion 122, and the sucked oil is discharged from the receiving cavity 111 through the fuel supply pipe portion 123 and flows to the components that need to supply fuel in the vehicle.

[0042] It can be understood that in the embodiments of the present application, since at least the inner wall of the bottom of the accommodation cavity 111 is set as an arc surface, when the vehicle is driving on a complex road surface such as a slope, the fuel in the accommodation cavity 111 is more likely to flow along the inner wall of the arc surface. At the same time, since the gravity component 130 is arranged in the accommodation cavity 111 and the gravity component 130 is also connected to the oil suction pipe portion 122, when the fuel tank structure 100 is tilted, the gravity component 130 can make the oil suction pipe portion 122 move in the direction close to the liquid level of the oil, so that the oil suction pipe portion 122 is always immersed in the fuel, which is convenient for the oil suction pipe portion 122 in the accommodation cavity 111 to suck the fuel, so as to avoid the phenomenon of flameout caused by the tilt of the liquid level of the oil resulting in the failure of the oil pump 150 to suck oil.

[0043] In addition, since the connecting portion 121 is connected to the housing 110 and the oil suction pipe portion 122 at the same time, the position of the oil suction pipe portion 122 can be fixed through the connecting portion 121, so as to avoid the problem that the oil suction pipe portion 122 deviates and cannot suck oil when the vehicle is driving on a complex road surface such as a slope. At the same time, it can also avoid the situation that the oil suction pipe portion 122 collides with the inner wall of the housing 110 to generate noise.

[0044] In some embodiments, as Figure 1 shown, the inner wall of the accommodation cavity 111 can be spherical, spherical crown-shaped or elliptical, so that when the vehicle is driving on a complex road surface such as a slope, the fuel in the fuel tank structure 100 will flow along the inner wall of the spherical, spherical crown-shaped or elliptical shape and be sucked by the oil suction pipe portion 122 in the accommodation cavity 111, so as to avoid the phenomenon of flameout caused by the tilt of the liquid level of the oil resulting in the failure of the oil pump 150 to suck oil. In particular, when the inner wall of the accommodation cavity 111 is spherical or spherical crown-shaped, when the fuel tank structure 100 is tilted, no matter how many angles it is tilted, the tilted place must also be the lowest place of the accommodation cavity 111, and the fuel will necessarily gather at this lowest place. Moreover, since the oil suction pipe portion 122 is kept arranged along the gravity direction under the action of the gravity component 130, that is, the end of the oil suction pipe portion 122 (which is the oil inlet 1221 below) will necessarily be located at this lowest place, so as to ensure that the end of the oil suction pipe portion 122 is always in the fuel, ensuring that the oil suction pipe portion 122 has fuel to suck.

[0045] In some specific embodiments, the housing 110 itself, that is, the outer contour of the housing 110 is also spherical or spherical crown-shaped.

[0046] In some embodiments, as Figure 2 and Figure 3 shown, the oil suction pipe portion 122 is provided with an oil inlet 1221, and the oil inlet 1221 is arranged at one end of the oil suction pipe portion 122 away from the oil pump 150. The oil inlet 1221 is used to suck the oil in the accommodation cavity 111 under the action of the oil pump 150. At the same time, please continue to refer to Figure 2 and Figure 3, in this embodiment, the gravity component 130 can be located at one end of the oil suction pipe portion 122 close to the oil inlet 1221 and at the bottom of the housing 110. In this way, when the gravity component 130 drives the oil pipe portion 122 to move towards the bottom of the housing 110, since the gravity component 130 is arranged at one end close to the oil inlet 1221, it can better ensure that the oil inlet 1221 also moves synchronously and always remains in the fuel, so that the oil suction effect can be achieved even when the liquid level of the oil in the accommodation cavity 111 is relatively low, thereby improving the driving stability of the vehicle.

[0047] It should be noted that in this embodiment, the specific number of the oil suction pipe portions 122 is not limited. For example, it can be composed of two, three or more, and is not limited here.

[0048] In some embodiments, such as Figure 2 and Figure 3 shown, the gravity component 130 can include a main body 131 and a filter element 132 for filtering the fuel in the accommodation cavity 111. Among them, an installation through hole 133 is provided on the main body 131. The installation through hole 133 penetrates through the opposite ends of the main body 131. Among them, the oil suction pipe portion 122 is fixedly connected to one end of 133, and the oil inlet 1221 is located in the installation through hole 133. The filter element 132 is also arranged in the installation through hole 133 and is located at the end of the installation through hole 133 away from the oil suction pipe portion 122. When the oil suction pipe portion 122 sucks oil, the fuel in the accommodation cavity 111 first passes through the filter element 132 for filtering and then enters the installation through hole 133, and then enters the oil suction pipe fitting 120 from the oil inlet 1221. It can be understood that in this embodiment, the filter element 132 is used to filter the oil in the accommodation cavity 111 and enable the filtered oil to flow through the installation through hole 133 and the oil suction pipe portion 122.

[0049] In this embodiment, the outer wall of the main body 131 can be provided with an anti-corrosion rubber layer or the outer wall of the main body 131 is sleeved with an anti-corrosion rubber sleeve. On the one hand, the outer wall layer or rubber sleeve made of rubber can buffer the collision between the main body 131 and the inner wall of the accommodation cavity 111 when the gravity component 130 moves along the inner wall of the accommodation cavity 111; on the other hand, since the outer wall layer or rubber sleeve also has anti-corrosion properties, it also avoids the corrosion of the main body 131 caused by being immersed in fuel for a long time and improves the service life of the main body 131. More preferably, in order to reduce the sliding friction between the main body 131 and the inner wall of the accommodation cavity 111, the lower surface of the main body 131 can be set to be arc-shaped, or the main body 131 is spherical.

[0050] In some embodiments, the filter element 132 is disposed at the opening of the mounting through hole 133. Therefore, when the body 131 slides along the inner wall of the accommodating cavity 111, the filter element 132 will inevitably come into contact with the inner wall of the accommodating cavity 111. To reduce the contact friction, the lower surface of the filter element 132 may have the same surface curvature as the surface of the body 131 and form an integral body, which is not limited herein.

[0051] In some embodiments, as Figure 3 shown, the mounting through hole 133 may be a stepped hole. The mounting through hole 133 may include a first mounting hole 1331 and a second mounting hole 1332. Among them, the aperture of the first mounting hole 1331 is larger than that of the second mounting hole 1332. The first mounting hole 1331 is used to mount the filter element 132, and the second mounting hole 1332 is used to mount the oil suction pipe portion 122; and the filter element 132 and the oil inlet 1221 are spaced apart, so as to form an oil storage space 1333 between the oil inlet 1221 and the filter element 132 in the mounting through hole 133. After the fuel passes through the filter element 132, it is temporarily stored in the oil storage space 1333, that is, the oil storage space 1333 is used to temporarily store the filtered oil.

[0052] It can be understood that in other specific embodiments, the mounting through hole 133 may be a three-stage stepped hole, and a groove is formed at one end of the inner wall of the first mounting hole 1331 away from the second mounting hole 1332, so as to divide the first mounting hole 1331 into an oil storage section and a mounting section. Among them, the oil storage section forms an oil storage space 1333 in the mounting through hole 133, and the mounting section forms a space for mounting the filter element 132 in the mounting through hole 133.

[0053] It should be noted that in other embodiments of the present application, as Figure 3 shown, a connecting pipe 170 may also be included. The connecting pipe 170 can be inserted into the oil suction pipe portion 122, and the connecting pipe 170 is blocked on the step between the first mounting hole 1331 and the second mounting hole 1332, so as to prevent the oil suction pipe portion 122 from detaching from the mounting through hole 133, thereby achieving the purpose of stable connection between the oil suction pipe portion 122 and the mounting through hole 133.

[0054] In some embodiments, as Figure 1 and Figure 2As shown, a bracket 140 may also be provided in the accommodation cavity 111, and the connecting portion 121 is rotatably connected to the bracket 140. Specifically, in this embodiment, the bracket 140 is arranged along the chord length direction of the inner wall of the fuel tank structure 100 and fixedly connected to the inner wall. At the same time, the connecting portion 121 is connected to the midpoint of the length of the bracket 140 along the chord length direction, so as to ensure that before the vehicle travels on complex roads such as slopes, the gravity component 130 is located at the lowest position of the inner wall. It can be understood that if the inner wall is circular, the bracket 140 may be arranged along the diameter direction of the inner wall, and at the same time, the connecting portion 121 is located at the center of the circle.

[0055] Thus, when the vehicle travels on complex roads such as slopes, the flexibility of the connecting portion 121 and the oil suction pipe portion 122 can be further improved to avoid the situation of jamming of the oil suction pipe portion 122. At the same time, in this embodiment, please continue to refer to Figure 2 , the connecting portion 121 may be provided with a fixing hole 1211, and the oil suction pipe portion 122 can be connected to the fixing hole 1211 to achieve the purpose of fixing the oil suction pipe portion 122 through the fixing hole 1211.

[0056] It can be understood that in this embodiment, either the bracket 140 or the connecting portion 121 is a ball joint, and the other of the bracket 140 and the connecting portion 121 is a ball head, so as to achieve the purpose of rotational connection through the ball head connection method, and further achieve the purpose of simplifying the connection structure and saving costs. At the same time, the connecting portion 121 may be arranged at the center of the housing 110, and the connecting portion 121, the bracket 140 and the housing 110 are integrally formed, so as to further enhance the fixing effect and supporting effect on the oil suction pipe portion 122.

[0057] In some embodiments, as Figure 1 and Figure 2 shown, the housing 110 may also be provided with a fuel filling port 160, and the fuel filling port 160 is used to supplement external fuel into the accommodation cavity 111.

[0058] This application also provides a mobile device, including the fuel tank structure 100 described in any of the above embodiments.
