[0033] The following further describes the specific embodiments of the present utility model with reference to the accompanying drawings.

[0034] As Figure 1-8 shown, the steering storage oil tank of the present utility model includes a tank body mechanism 1, an oil filling mechanism 2 and a return oil pipe connection mechanism 3, and is characterized in that: the oil filling mechanism 2 and the return oil pipe connection mechanism 3 are both installed on the outer surface of the tank body mechanism 1 and communicate with the inside of the tank body mechanism 1, and a pressure assist mechanism 4 is also installed inside the tank body mechanism 1;

[0035] The tank body mechanism 1 includes a storage oil tank body 101, two limit grooves 102 opened on the upper inner wall and the lower inner wall of the storage oil tank body 101, two liquid outlet pipes 103 welded on the upper and lower sides of the outer surface of the storage oil tank body 101 and communicating with the inside of the storage oil tank body 101, and a limit slide bar 104 fixedly connected to the axis of the limit groove 102;

[0036] The oil filling mechanism 2 includes an inlet oil pipe 201, a diverging pipe 202 fixed to the top end of the inlet oil pipe 201 and communicating with the inside of the storage oil tank body 101, the outlet ends of the diverging pipe 202 are respectively located on the upper and lower sides of the storage oil tank body 101, a cross support frame 203 is fixedly connected to the inner wall of the outlet end of the diverging pipe 202, a sealing slider 204 is movably connected to the inner wall of the outlet end of the diverging pipe 202, and an elastic traction member 205 is installed between the cross support frame 203 and the sealing slider 204;

[0037] The return oil pipe connection mechanism 3 includes an oil pipe connector 301 threadedly connected to the top end of the liquid outlet pipe 103, a concave card slot 302 opened on the outer surface of the oil pipe connector 301, and a filter element 303 arranged inside the oil pipe connector 301;

[0038] The pressure assistance mechanism 4 includes a power valve plate 401 penetrated by a limited-position slide rod 104. The power valve plate 401 divides the interior of the oil storage tank body 101 into two chambers. Conical heads 402 are fixedly connected to both the upper and lower sides of the power valve plate 401. Under the action of the oil fluid thrust, the power valve plate 401 will approach the liquid outlet pipe 103. The conical heads 402 are set in a conical shape, so that there is a gap between the conical heads 402 and the liquid outlet pipe 103, avoiding blockage of the mouth of the liquid outlet pipe 103 by the conical heads 402 and resulting in inability to return oil. Support elastic members 403 are lapped on the conical heads 402 on both the upper and lower sides, and the support elastic members 403 are sleeved on the limited-position slide rod 104 and lapped with the limited-position grooves 102.

[0039] Through the above technical solution, the limited-position slide rod 104 is fixedly connected to the axis inside the oil storage tank body 101, and the power valve plate 401 is sleeved on the surface of the limited-position slide rod 104 to divide the interior of the oil storage tank body 101 into two chambers. At the same time, two support elastic members 403 are used to limit the power valve plate 401 to the axis of the oil storage tank body 101. When oil fluid is transported, the power valve plate 401 is pressed to push the liquid into the corresponding liquid outlet pipe 103 to cooperate with the vehicle steering gear. When the direction needs to be straightened, the power valve plate 401 loses the continuous pressure and will return to the initial position under the action of the support elastic members 403, thereby reducing the output force of the vehicle steering gear and achieving the effect of reducing the burden on the vehicle steering gear;

[0040] By fixedly connecting a cross support frame 203 inside the shunt pipe 202 and connecting an elastic traction member 205 to the cross support frame 203 to traction the sealing slider 204, when adding oil fluid, the pressure will push the sealing slider 204 out of the shunt pipe 202 to connect the interior of the shunt pipe 202 with the interior of the oil storage tank body 101. When stopping adding oil fluid, the sealing slider 204 will return to the interior of the shunt pipe 202 under the action of the pulling force of the elastic traction member 205 for sealing, and is pushed by the oil pressure in the oil storage tank body 101 and limited by the cross support frame 203, without the need to use a sealing cover additionally, achieving the effect of convenient oil fluid addition;

[0041] By opening a recessed card slot 302 on the oil pipe connector 301, it is convenient to fix when connecting the return oil pipe. Moreover, the step formed by the recessed card slot 302 in the oil pipe connector 301 cooperates with the step inside the liquid outlet pipe 103 to limit the filter element 303, and the liquid outlet pipe 103 and the oil pipe connector 301 are connected by a threaded connection. After long-term use, the filter element 303 can be conveniently replaced, achieving the effects of firm fixation of the return oil pipe and convenient replacement of the filter element 303.

[0042] Specifically, the diameter of the pipe opening of the liquid outlet pipe 103 is trapezoidal, with a larger outer portion and a smaller inner portion, and a threaded groove is provided on the inner wall of the pipe opening of the liquid outlet pipe 103 .

[0043] Through the above technical solution, the inner wall of the outlet pipe 103 is set to a trapezoidal shape to limit the filter element 303 and prevent the filter element 303 from penetrating too deep into the liquid outlet pipe 103 and making it inconvenient to replace.

[0044] Specifically, the outer surface of the limiting sliding rod 104 is a smooth surface, and the limiting sliding rod 104 is a vertical rod.

[0045] Through the above technical solution, a limiting slide 104 is set to limit the power valve plate 401, so that the power valve plate 401 can move stably. The limiting slide 104 is set to a smooth surface, and with the cooperation of oil, the friction between the limiting slide 104 and the power valve plate 401 can be reduced.

[0046] Specifically, the cross support frame 203 includes cross-shaped support rods and a column connecting the support rods in the middle. A groove is provided in the middle of the column, and a shaft is fixedly connected in the middle of the groove.

[0047] Through the above technical solution, the support rod is cross-crossed and fixedly connected to the inside of the diverter pipe 202, so that the oil can flow while supporting the column, and a groove is opened at the axis of the column and the shaft is connected, so that it can be connected to the end of the elastic traction member 205.

[0048] Specifically, the diameter of the sealing slider 204 is equal to the inner diameter of the diversion tube 202. An arc-shaped surface is set on the side of the sealing slider 204 close to the cross support frame 203, and the axis of the arc-shaped surface is fixedly connected to a column with the same axis as the cross support frame 203. The two columns are connected to the elastic traction member 205 through an axis rod.

[0049] Through the above technical solution, the diameter of the sealing slider 204 is set so that the sealing slider 204 can seal the end of the diverter tube 202, and one side of the sealing slider 204 is set to an arc-shaped surface, so that when the sealing slider 204 is pushed out of the diverter tube 202 and loses pressure to rebound, the arc-shaped surface can enable the sealing slider 204 to enter the interior of the diverter tube 202 more stably, thereby avoiding the sealing slider 204 from being stuck at the mouth of the diverter tube 202.

[0050] Specifically, the head of the oil pipe connector 301 is conical, and the inner diameter of the oil pipe connector 301 at the position of the recessed slot 302 is reduced.

[0051] Through the above technical solution, the head of the oil pipe connector 301 is set to be conical, which can be conveniently inserted into the inside of the return oil pipe. By setting the inner diameter of the oil pipe connector 301, it can cooperate with the inside of the liquid outlet pipe 103 to limit the filter element 303.

[0052] Specifically, the filter element 303 is installed inside the connection between the liquid outlet pipe 103 and the oil pipe connector 301, and the outer surface of the filter element 303 is respectively lapped with the inner walls of the liquid outlet pipe 103 and the oil pipe connector 301.

[0053] Through the above technical solution, the filter element 303 is installed at the connection between the liquid outlet pipe 103 and the oil pipe connector 301 and lapped with the inner walls of the liquid outlet pipe 103 and the oil pipe connector 301. While filtering impurities in the oil, the filter element 303 can be conveniently replaced by removing the oil pipe connector 301.

[0054] Specifically, a groove is opened at the axis of the end of the conical head 402 away from the power valve plate 401, and the diameter of the groove on the conical head 402 is equal to the diameter of the limit groove 102.

[0055] Through the above technical solution, a groove is opened on the conical head 402 to cooperate with the limit groove 102 to limit the support elastic member 403, avoiding the deviation of the support elastic member 403 after being compressed and contracted.

[0056] Specifically, the number of the support elastic members 403 is two. The two support elastic members 403 are respectively located at both ends of the power valve plate 401, and both ends of the support elastic member 403 are respectively inserted into the limit groove 102 and the groove of the conical head 402, and the elasticity of the two support elastic members 403 is equal.

[0057] Through the above technical solution, two support elastic members 403 are provided to simultaneously apply pressure to the power valve plate 401, so that the power valve plate 401 is located at the center of the oil storage tank body 101 when the pressure is balanced. After the power valve plate 401 is stressed in any direction, the power valve plate 401 can be supported by the support elastic member 403 and rebound.

[0058] During use, a limiting slide rod 104 is fixedly connected to the axis inside the oil storage tank body 101, and a power valve plate 401 is sleeved on the surface of the limiting slide rod 104 to divide the interior of the oil storage tank body 101 into two chambers. At the same time, two support elastic members 403 are used to limit the power valve plate 401 to the axis of the oil storage tank body 101. When oil is being transported, the power valve plate 401 is pressed to push the liquid into the corresponding liquid outlet pipe 103 to cooperate with the vehicle steering gear. When it is necessary to return to the straight-ahead position, the power valve plate 401 loses the continuous pressure and will return to the initial position under the action of the support elastic member 403, thereby reducing the output force of the vehicle steering gear and achieving the effect of reducing the burden on the vehicle steering gear;

[0059] A cross support frame 203 is fixedly connected inside the shunt pipe 202, and an elastic traction member 205 is connected to the cross support frame 203 to traction the sealing slider 204. Thus, when adding oil, the pressure will push the sealing slider 204 out of the shunt pipe 202 to connect the interior of the shunt pipe 202 with the oil storage tank body 101. When adding oil stops, the sealing slider 204 will return to the interior of the shunt pipe 202 under the action of the pulling force of the elastic traction member 205 for sealing and is pushed by the oil pressure in the oil storage tank body 101 and limited by the cross support frame 203, eliminating the need for an additional sealing cover and achieving the effect of convenient oil addition;

[0060] By providing a recessed card slot 302 on the oil pipe connector 301, it is convenient to fix when connecting the return oil pipe. Moreover, the step formed by the recessed card slot 302 in the oil pipe connector 301 cooperates with the step inside the liquid outlet pipe 103 to limit the filter element 303. The liquid outlet pipe 103 and the oil pipe connector 301 are connected by a threaded connection, and the filter element 303 can be conveniently replaced after long-term use, achieving the effects of firm fixing of the return oil pipe and convenient replacement of the filter element 303.
