Description

Technical Field

[0001] The invention relates to the technical field of vehicle fuel tanks, and in particular to a safety protection structure applied to automobile fuel tanks. Background Art

[0002] The car fuel tank is a vital component of the car fuel system. The main function of the car fuel tank is to store fuel, which is necessary for the normal operation of the car engine. The fuel is transported to the engine's fuel injection system through the fuel tank to provide power for the car. The car fuel tank capacity varies depending on the model. The fuel tank capacity of a small truck is about 60 liters, the fuel tank capacity of a large truck is about 140 liters, and the fuel tank capacity of a large trailer can reach more than 200 liters.

[0003] The existing fuel tanks of large trucks and trailers are usually fixed on one side of the frame body due to their large size, and the fuel tanks are usually directly exposed to the external environment. Since large trucks and trailers hold a large amount of fuel, in the event of an unexpected traffic accident, if external objects or other vehicles directly collide with the fuel tank, there are certain safety hazards. Summary of the invention

[0004] The purpose of the present invention is to solve the problems existing in the prior art:

[0005] The existing fuel tanks of large trucks and trailers are usually fixed on one side of the frame body due to their large size, and the fuel tanks are usually directly exposed to the external environment, which poses certain safety hazards.

[0006] A safety protection structure applied to automobile fuel tanks is proposed.

[0007] In order to achieve the above object, the present invention adopts the following technical solutions:

[0008] A safety protection structure applied to an automobile fuel tank comprises an upper cross bar, a middle cross bar and a lower cross bar arranged on one side of a fuel tank body. The fuel tank body is arranged on one side of a frame body. Two upper extension bars are symmetrically fixed to the upper cross bar on a side close to the fuel tank body, two middle extension bars are symmetrically fixed to the middle cross bar on a side close to the fuel tank body, and two lower extension bars are symmetrically fixed to the lower cross bar on a side close to the fuel tank body. A plurality of reinforcing members are arranged between the upper cross bar and the lower cross bar, and each reinforcing member passes through the middle cross bar.

[0009] As a further technical solution of the present invention, each of the reinforcement members comprises a hollow tube, each of the hollow tubes passes through the upper cross bar, the middle cross bar and the lower cross bar in sequence, and a limiting column is fixed to the upper end of each hollow tube.

[0010] As a further technical solution of the present invention, a threaded column is fixed to the lower end of each hollow tube, and a locking nut is threadedly sleeved on each threaded column.

[0011] As a further technical solution of the present invention, a connecting piece is provided between each of the upper extension rod, the middle extension rod and the lower extension rod and the frame body.

[0012] As a further technical solution of the present invention, each of the connecting parts includes a connecting seat fixed to one side of the frame body, a connecting block is fixed to one side of the connecting seat, the connecting block corresponding to the upper extension rod passes through the upper extension rod, the connecting block corresponding to the middle extension rod passes through the middle extension rod, and the connecting block corresponding to the lower extension rod passes through the lower extension rod, and multiple locking bolts are arranged between the upper extension rod, the middle extension rod and the lower extension rod and the corresponding connecting blocks.

[0013] As a further technical solution of the present invention, the upper end surface of the oil tank body is provided with an oil tank mouth, and movable plates are movably provided on both sides of the oil tank mouth, and upper baffles are fixed on the opposite surfaces of the two movable plates and close to the upper ends, and two guide rods are fixed between the two upper extension rods, and each guide rod movably penetrates the movable plate, and a screw rod is rotatably provided between the two upper extension rods, and the screw rod thread penetrates the two movable plates, and a driving assembly for use with the screw rod is provided on the upper extension rod.

[0014] As a further technical solution of the present invention, the driving assembly includes a mounting seat fixed to one side of the upper extension rod, a side through groove is penetrated through one side of the mounting seat, a rotating cylinder is rotatably arranged in the side through groove, two connecting keys are symmetrically fixed on the inner wall of the rotating cylinder, and a rotating part used in conjunction with the rotating cylinder is detachably arranged on one side of the mounting seat, and one end of the screw rod is rotatably penetrated through the upper extension rod and fixedly connected to the end of the rotating cylinder.

[0015] As a further technical solution of the present invention, the rotating member includes a rotating hand wheel, a connecting column is fixed to one side of the rotating hand wheel, and two key grooves for matching with the connecting key are provided on the surface of the connecting column.

[0016] As a further technical solution of the present invention, the lower end surfaces of the two upper baffles are detachably provided with the same lifting plate, and two plug-in blocks are symmetrically fixed on the upper end surface of the lifting plate. The lower end surface of each upper baffle is provided with a plug-in groove for cooperating with the plug-in block.

[0017] As a further technical solution of the present invention, a first magnet layer is fixed to the upper end surface of each plug-in block, a second magnet layer is fixed to the inner top of each plug-in slot, and the second magnet layer is magnetically attracted to the first magnet layer.

[0018] Beneficial effects of the present invention:

[0019] 1. When in use, the upper cross bar, the middle cross bar and the lower cross bar are provided to block and protect the side of the fuel tank body, and the multiple reinforcements are provided to further strengthen the blocking protection of the vacant part of the side of the fuel tank body on the one hand, and on the other hand, the upper cross bar, the middle cross bar and the lower cross bar are connected with the multiple reinforcements into a whole to increase the collision buffer strength.

[0020] 2. In the initial state, the two movable plates are located on both sides of the fuel tank mouth, and the two upper baffles are butt-jointed and covered on the upper end surface of the fuel tank mouth. The cooperation of the movable plates and the upper baffles protects the fuel tank mouth to prevent the fuel tank mouth from being easily opened, which would cause the oil in the fuel tank body to be stolen. When the fuel tank body needs to be refueled, the drive assembly drives the screw rod to rotate, thereby causing the two movable plates to move away from each other with the corresponding upper baffles, exposing the fuel tank mouth. The fuel tank mouth is easy to use and has a certain degree of anti-theft performance.

[0021] 3. When it is necessary to drive the screw to rotate, insert the connecting column at one end of the rotating handwheel into the rotating cylinder until the keyway and the connecting key are connected. When the rotating handwheel is turned, the keyway and the connecting key are matched to drive the rotating cylinder and the screw to rotate. When the tank body is refueled and the two upper baffles are docked together, remove the rotating handwheel from one side of the mounting seat and place it in the vehicle cab. At this time, the end of the rotating cylinder is flush with the side wall of the mounting seat, which makes it inconvenient to use other methods to drive the rotating cylinder to drive the screw to rotate, thereby increasing the anti-theft performance.

[0022] 4. When the two upper baffles are butt-jointed together, the two plug-in blocks on the upper end surface of the lifting plate are respectively plugged into the corresponding plug-in grooves, and the plug-in blocks and the lifting plate are adsorbed and fixed by the provided magnet layer 2 and magnet layer 1. At this time, the lifting plate cooperates with the two plug-in blocks to limit and fix the two upper baffles, so that the two upper baffles cannot be displaced, and the lifting plate and the plug-in blocks have a certain degree of concealment. If the lifting plate and the plug-in blocks are not removed, the screw rod cannot be rotated, which further increases the anti-theft performance. BRIEF DESCRIPTION OF THE DRAWINGS

When the fuel tank body 1 is refueled, the two upper baffles 17 are docked together, and the rotating hand wheel 23 is removed from one side of the mounting seat 20 and placed in the vehicle cab. At this time, the end of the rotating cylinder 21 is flush with the side wall of the mounting seat 20, and it is inconvenient to use other methods to drive the rotating cylinder 21 to drive the screw rod 19 to rotate, thereby increasing the anti-theft performance.

When the rotating hand wheel 23 is rotated, the key slot 25 and the connecting key 22 are matched to drive the rotating cylinder 21 and the screw rod 19 to rotate. When the fuel tank body 1 is refueled, the two upper baffles 17 are docked together, and the rotating hand wheel 23 is removed from one side of the mounting seat 20 and placed in the vehicle cab.
