In addition, four enlarged gaps are processed on the outer circumference of the energy accumulator sealing cover or a through hole is processed in the center of the sealing cover, so that external water easily enters a cavity between the energy accumulator piston and the sealing cover when the energy accumulator sealing cover is immersed in water.
SUMMERY OF THE UTILITY MODEL
In order to solve the technical problem, the utility model provides a sealed effectual, the working medium does not leak the car braking low pressure energy storage ware.
The utility model provides a following technical scheme:
the utility model provides an automobile brake low pressure energy storage ware, includes piston, sealing washer, reset spring and closing cap, the piston outer wall is opened along the circumferencial direction has the ring channel, the sealing washer is installed in the ring channel of piston periphery, the piston is inside to be opened there is the holding tank of placing reset spring, the piston top is the closing cap, reset spring installs between closing cap and piston, the holding tank bottom of piston is provided with the bellying.
Further, the convex part comprises a central bulge and an annular bulge, the central bulge is positioned in the center of the annular bulge, and the height of the central bulge is greater than that of the annular bulge.
Furthermore, the sealing cover comprises a bottom groove and a ring edge connected with the bottom groove, and the ring edge is provided with a notch.
Compared with the prior art, the beneficial effects of the utility model are that: the utility model discloses a low pressure energy storage ware, piston bottom have the bellying, and structural strength is higher, and the piston pressure-bearing is great, and the periphery of the closing cap of energy storage ware only has a breach, and breach part and HCU body coincidence after the assembly only keep a little part in circumference top and inside to ventilate, and outside water is difficult to get into in the cavity between energy storage ware piston and the closing cap when soaking. Is suitable for various complex environments.

In the figure: 1. a piston; 2. a seal ring; 3. a return spring; 4. a sealing cover 41, a bottom groove 42, a ring edge 43 and a notch; 5. an annular groove; 6. a boss 61, a central boss, 62, an annular boss; 7. and (6) accommodating the tank.
Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.
Please refer to fig. 1-2, the utility model discloses an automobile brake low pressure energy accumulator, including piston 1, sealing washer 2, reset spring 3 and closing cap 4, 1 outer wall of piston is opened along the circumferencial direction has ring channel 5, sealing washer 2 is installed in ring channel 5 of 1 periphery of piston, 1 inside the opening of piston has the holding tank 7 of placing reset spring, 1 top of piston is closing cap 4, reset spring 3 installs between closing cap 4 and piston 1, 7 bottoms of holding tank of piston 1 are provided with bellying 6, the thickening design of this kind of bellying 6 can improve piston structural strength and compressive capacity.
The boss 6 includes a central protrusion 61 and an annular protrusion 62, the central protrusion 61 is located at the center of the annular protrusion 62, and the height of the central protrusion 61 is greater than that of the annular protrusion 26. The return spring 3 is clamped between the annular bulge 26 and the inner wall of the piston 1.
The closure 4, typically made by stamping, is of shallow cup-like configuration. The sealing cover 4 comprises a bottom groove 41 and an annular edge 42 connected with the bottom groove 41, a notch 43 is formed in the annular edge 42, the notch 43 is partially overlapped with the HCU body after assembly, only a small part of the top of the circumference is reserved for ventilation with the inside, only spring reset force is guaranteed in the working process of the energy accumulator, and meanwhile, small gaps guarantee that water cannot enter the cavity of the HCU energy accumulator.
The piston 1 is mounted in a corresponding bore of a hydraulic valve block of an automotive brake system. The sealing cover 4 and the corresponding hole of the hydraulic valve block are fixed by extrusion molding of materials.
In the initial state, the bottom surface of the piston is in contact with the bottom surface of the corresponding hole of the hydraulic valve block due to the action of the return spring, and the accumulator does not store any solution. When the brake wheel cylinder is depressurized, the oil pressure overcomes the reset spring force acting on the bottom surface of the piston to push the piston to move, and when the upper part of the piston is contacted with the bottom of the sealing cover, the storage volume of the energy accumulator reaches the maximum. As the oil stored in the accumulator is pumped out by the plunger pump, the pressure of the solution in the accumulator decreases and the piston moves downward under the force of the spring.
The utility model discloses a low pressure energy storage ware, 1 bottom of piston have the bellying, and structural strength is higher, and the piston pressure-bearing is great, and the periphery of the closing cap 4 of energy storage ware only has a breach 43, and breach 43 part coincides with the corresponding hole of hydraulic valve piece after the assembly, only leaves a little part in circumference top and inside ventilation, and outside water is difficult to get into in the cavity between energy storage ware piston and the closing cap when soaking. Is suitable for various complex environments.
Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
