Description

Technical Field

[0001] The invention relates to the technical field of storage containers, in particular to an anti-leakage oil tank for automobiles. Background Art

[0002] A car fuel tank, also known as a car fuel tank, is a container for storing fuel in a car. It is the only place to store fuel in a car that uses fuel as fuel, and it is also the power source of the engine. Its main functions include storing fuel, transporting fuel, managing gasoline evaporation, and measuring and controlling oil volume. Currently, cars generally use plastic fuel tanks, which have the characteristics of light weight, corrosion resistance, and good electrical insulation.

[0003] At present, automobile fuel tanks are generally installed at the rear of the bottom of the vehicle. When the driving environment of the vehicle is relatively harsh, the exposed fuel tank will be scratched by sharp objects in the passing environment, which will cause scratches, cracks or even scratches on the fuel tank, resulting in fuel leakage. In dangerous environments, the leaked fuel will also be ignited, causing safety accidents. Some existing vehicles have a protective mechanism (such as a guard plate mechanism) on the lower side of the fuel tank when they leave the factory. The guard plate is used to block the scratches and collisions of external objects on the fuel tank to avoid leakage of the fuel tank body. The guard plate is mainly divided into two types of plastic materials and metal materials. The commonly used metal guard plate has the advantages of strong protective performance and no breakage compared to the plastic guard plate, but it will cause the guard plate to deform when it is subjected to external collision. When the deformation amplitude is large, it is difficult to reset itself, which will cause squeezing of the plastic fuel tank, causing deformation of the plastic fuel tank, affecting the elastic reset ability of the plastic fuel tank itself, and may change the lowest position of the liquid level detection float in the fuel tank, affecting the liquid level detection function of the fuel tank and reducing the liquid storage capacity of the fuel tank. Therefore, according to the above problems, an anti-leakage automobile fuel tank is proposed. Summary of the invention

[0004] The purpose of the present invention is to provide an anti-leakage automobile fuel tank to solve the problem that the existing automobile fuel tank is prone to leakage due to bottom impact when driving on harsh roads. Although the commonly used metal guard plate has the advantages of strong protective performance and no breakage compared with the plastic guard plate, it can protect the fuel tank, but it is easy to be greatly deformed when subjected to external impact, thereby causing pressure on the fuel tank body.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] 1. In the present invention, by providing structures such as a fixing module, an inner support module, a lower card shell and a lower stopper, the fixing module can fix the inner support module, the lower card shell and the lower stopper at the lower position of the box body, and the lower card shell can fix the lower stopper at the lower side of the inner support module. The rope body arranged in the inner support module can be stretched on the upper side of the lower stopper by the positioning arc plate and the groove limiter, and the parallel bars and tension springs connected to the two ends of the rope body can make the arranged and unfolded rope body reset when subjected to external pressure, and the rope body is connected to the metal plate by the limit of the card strip and the insertion strip, so that the metal plate can be positioned and internally supported at the same time, and the metal plate can be buffered when it is hit and scratched by the bottom, so as to reduce the deformation amplitude of the metal plate when subjected to external pressure and improve the recovery of the metal plate. The metal plate can protect the fuel tank body from damage and leakage, and can also prevent the metal plate from being greatly deformed and causing pressure on the fuel tank. This ensures that the fuel tank of the automobile will not leak in a bad road through the protective mechanism. The protective mechanism supports the metal plate based on the advantages of the metal plate's own high protective performance and no breakage, improves its reset performance, and prevents it from being greatly deformed and the fuel tank body from being compressed. This solves the problem that the existing automobile fuel tank is prone to leakage due to bottom impact when driving on a bad road. Although the commonly used metal guard plate has the advantages of strong protective performance and no breakage compared to the plastic guard plate, and can protect the fuel tank, it is prone to be greatly deformed when subjected to external impact, thereby causing pressure on the fuel tank body.

[0016] 2. In the present invention, by providing structures such as a rope body, parallel bars, tension springs and a detection module, the arranged rope body cooperates with the parallel bars and tension springs to support the metal plate. When the metal plate is impacted from the outside, it will sag upward and push the flat middle part of the rope body to bend upward. The bending of the rope body can pull the parallel bars on both sides to move downward. It can be seen that the downward movement of the parallel bars represents that the metal plate is impacted from the outside, and the downward displacement of the parallel bars can be detected by the detection module. The detection process is as follows: the downward movement of the parallel bars will press down the corner block, and the linkage of the rail block will drive the collar, folding rod and pressure block to move downward. The pressure block will move downward according to the downward movement amplitude of the parallel bars. The three contact buttons from top to bottom in the outer shell represent different degrees of downward movement of the pressure block. The larger the amplitude, the larger the amplitude of the impact. After the contact button contacts the downward pressure block, a signal will be sent to the driver's terminal through the signal transmitter. The driver can determine the amplitude of the impact on the fuel tank through the different signals received, so that the car fuel tank can send an alarm signal to the driver when it is hit, and the amplitude of the impact on the fuel tank can be determined through the signal, so that maintenance can be performed after driving. This solves the problem that the driver's car body will remain in a bumpy state when driving on a bad road. At this time, when the fuel tank is hit by an external impact, the driver is likely to ignore the impact due to the bumping of the car body. After driving, the fuel tank will not be maintained and inspected due to the neglect of the impact, and the damage to the fuel tank may affect subsequent driving.

[0017] 3. In the present invention, by providing structures such as a driving module, a flow stabilizing module and a wave-proof frame, the wave-proof frame can perform normal flow stabilization on the fuel in the fuel tank, reduce the impact of fuel surge on the fuel tank, and enable the car to travel stably. When the vehicle is traveling on a bad road and the fuel tank is subjected to external impact, the fluctuation and impact of the fuel in the fuel tank will increase suddenly, thereby affecting the stability of the vehicle at this time. The driving module and the flow stabilizing module can assist the wave-proof frame in stabilizing the flow of the fuel and smooth out the fluctuation of the fuel caused by the external impact. This realizes that the automobile fuel tank can automatically improve the flow stabilization performance of the fuel when it is subjected to external impact, avoids the impact of the sudden increase of fuel fluctuation on the fuel tank, and ensures the stability of the car when driving. This solves the problem that when the vehicle is traveling on a bad road and the fuel tank is subjected to external impact, the fluctuation and impact of the fuel in the fuel tank will increase suddenly, and the flow stabilization performance of the wave-proof frame cannot be improved accordingly, which will affect the fuel tank and the driving stability of the car.

[0044] Working process: The following actions may occur when a vehicle using an anti-leakage oil tank is driving on a bad road. The inner support module 4, the lower card shell 5, and the lower block 6 can be fixed at the lower position of the box body 1 through the fixing module 3. The lower card shell 5 can fix the lower block 6 on the lower side of the inner support module 4. The rope body 45 arranged in the inner support module 4 can be limited and supported on the upper side of the lower block 6 through the positioning arc plate 42 and the groove 43, and the parallel bar 46 and the tension spring 47 connected to the two ends of the rope body 45 can make the arranged and unfolded rope body 45 reset when subjected to external pressure, and the rope body 45 is connected to the metal plate 61 through the limit of the card strip 62 and the insertion strip 64, so that the metal plate 61 can be positioned and internally supported at the same time. When the bottom is hit and scraped, the unfolded rope body 45 can support and cushion the metal plate 61. The metal plate 61 will be concave upward and push the flat part of the rope body 45 to bend upward. The bending of the rope body 45 can pull the parallel bars 46 on both sides to move downward, and at the same time extend the tension spring 47 (the tension spring 47 will be affected by the damping blocks on both sides when the parallel bar 46 moves, which is fast and stable). After the impact, the tension spring 47 will shrink and reset to pull up the parallel bar 46. The upward movement of the parallel bar 46 can straighten and unfold the bent rope body 45 again. The straightening and unfolding of the rope body 45 can drive the metal plate 61 to reset, reducing the deformation amplitude of the metal plate 61 when it is subjected to external pressure and improving the reset performance of the metal plate 61, so that the metal plate 61 can protect the fuel tank body. 1 will not be damaged or leaked, and it can avoid the metal plate 61 from being greatly deformed to cause pressure on the fuel tank, so that the automobile fuel tank can ensure that the box body 1 will not leak in a harsh path through the protective mechanism, so that the protective mechanism can support the metal plate 61 based on the advantages of high protection performance and no breakage of the metal plate 61 itself, improve its reset performance, avoid it from being greatly deformed, and avoid the fuel tank body 1 from being compressed. The installation operation of the lower card shell 5 and the lower block 6 is as follows: place the lower block 6 in the placement groove 52 of the lower card shell 5 on both sides, move the lower card shell 5 upward to squeeze the spring pin 44 through the squeezing strip 53, so that the spring pin 44 shrinks back into the countersunk hole of the positioning arc plate 42, until the bayonet 54 is aligned with the countersunk hole as the squeezing strip 53 moves upward, and then When the spring pin 44 in the countersunk hole is ejected, it is stuck in the inner side of the bayonet 54 to complete the positioning of the lower card shell 5. At this time, the lower block 6 is pressed between the lower card shell 5 and the positioning arc plate 42, and at the same time, each rope body 45 will be in each slot of the card strip 62 (the rope body 45 is stretched straight so that the rope body 45 can directly enter the slot of the card strip 62 as the lower block 6 moves upward). At this time, each insertion strip 64 is horizontally inserted into the slot 63 to limit the rope body 45, so that the rope body 45 forms a connection relationship with the lower block 6, and the installation of the lower card shell 5 and the lower block 6 is completed. The operation of the fixing module 3 is as follows: the fixing module 3 is placed on the inner side of the installation position 2, the card of the positioning mechanism 36 is moved upward, and the rotating member 37 is rotated. Due to the meshing of a group of bevel gears 38,The rotating member 37 can drive the forward and reverse threaded screws 33 to rotate, and the wire blocks 34 and the pressing parts 32 on both sides are displaced to both sides through linkage to squeeze and adsorb the installation position 2, and then the clamps of the positioning mechanism 36 are released, and the rotating member 37 is positioned by the falling clamps to prevent it from rotating by itself, thereby completing the fixing operation; the detection operation of the impact is as follows, the metal plate 61 can be supported by the arranged rope body 45 in conjunction with the parallel bar 46 and the tension spring 47, and the metal plate 61 will be concave upward when the metal plate 61 is impacted from the outside and push the middle flat part of the rope body 45 to bend upward, and the bending of the rope body 45 can pull the parallel bars 46 on both sides to move downward, so that it can be seen that the downward movement of the parallel bar 46 means that the metal plate 61 is impacted from the outside, and the downward displacement of the parallel bar 46 can The detection module 7 detects that the detection process is as follows: the downward movement of the parallel bar 46 will press down the corner block 753, and the linkage of the track block 752 will drive the ring 751, the folding rod 754 and the pressure block 755 to move downward. The pressure block 755 will move downward according to the downward movement amplitude of the parallel bar 46. The three contact buttons 77 from top to bottom in the shell 71 represent the different degrees of downward movement of the pressure block 755. The greater the downward movement amplitude of the pressure block 755, the greater the amplitude of the impact. After the contact button 77 contacts the downward pressure block 755, it will send a signal to the driver's terminal through the signal transmitter 78. The driver can determine the amplitude of the impact on the fuel tank through the different signals received, so that the automobile fuel tank can send an alarm signal to the driver when it is hit, and can also be used to The signal determines the amplitude of the impact on the fuel tank so that maintenance can be performed after driving; when the fuel tank is subjected to external impact, the fuel flow stabilization operation is as follows. First, the wave-proof frame 10 can perform normal stabilization on the fuel in the fuel tank to reduce the impact of fuel surge on the fuel tank, so that the car can travel stably. When the vehicle is traveling on a harsh path and the fuel tank is subjected to external impact, the fuel fluctuation and impact in the fuel tank will increase sharply, thereby affecting the stability of the vehicle at this time. The drive module 8 and the flow stabilization module 9 can assist the wave-proof frame 10 in stabilizing the fuel flow and smoothing the fluctuation of the fuel caused by external impact. The operation is as follows. First, when the fuel tank is subjected to external impact, the parallel bar 46 will move downward, and the downward movement of the parallel bar 46 will drive the silk sleeve 842 to move downward. 42 cannot rotate, the downward movement of the wire sleeve 842 will drive the screw rod 841 to rotate at a high speed, and the high-speed rotation of the screw rod 841 can be driven by the bevel gear 844 and the bevel gear plate 846, so that the rotating shaft 845 drives the sleeve body 85 and the first strong magnet 86 to rotate at a low speed. When the exposed part of the first strong magnet 86 faces upward, the theory of like charges repel each other will push up the flow stabilizing module 9 with the second strong magnet 95. When the exposed part of the first strong magnet 86 faces downward, the flow stabilizing module 9 without the influence of repulsion will move downward due to the influence of gravity, and the up and down displacement of each grid bar 92 of the flow stabilizing module 9 can assist the wave-breaking frame 10 to quickly stabilize the suddenly fluctuating fuel, so that the automobile fuel tank can automatically improve the flow stabilizing performance of the fuel when it is hit by an external impact.Avoid the impact of sudden increase in fuel fluctuations on the fuel tank to ensure the stability of the car during driving.
