Description

Technical Field

[0001] The utility model relates to the technical field of automotive accumulators, and particularly to an adjustable automotive accumulator. Background Technique

[0002] An automotive accumulator is one of the most important components in an automobile. It often realizes the energy storage protection function through an energy storage airbag filled with nitrogen. However, there are still some defects in the specific use of such automotive accumulators.

[0003] The functionality of the automotive accumulator is poor. It is generally not easy to adjust the air pressure value of the nitrogen gas filled inside the energy storage airbag, nor is it easy to adjust the flow rate and capacity of the hydraulic oil filled. This results in that the energy storage effect of the device is not easy to adjust and the applicability is low. Secondly, when it is used for a long time, it often requires manual cleaning of the surface of the accumulator tank regularly to keep the outer wall of the device dry, clean, and avoid moisture and rust, which leads to low practicality of the device. Content of the Utility Model

[0004] The purpose of the utility model is to provide an adjustable automotive accumulator to solve the problems put forward in the above background technique.

[0005] To achieve the above purpose, the utility model provides the following technical solution: an adjustable automotive accumulator, including a PLC controller, an accumulator tank, and an annular air duct. Nitrogen gas filling ports and hydraulic oil reserved through ports are respectively arranged at the top and bottom of the accumulator tank. An energy storage airbag communicated with the nitrogen gas filling port is arranged inside the accumulator tank. An energy storage hydraulic oil activity cavity is arranged inside the accumulator tank outside the energy storage airbag. A pressure gauge and a manual control valve are successively installed on the nitrogen gas filling port. An electric flow control valve is installed at the bottom of the hydraulic oil reserved through port. The PLC controller is installed on one side of the accumulator tank. A timer is installed on the PLC controller. Annular reinforcing ribs and strip-shaped reinforcing ribs are uniformly fixed on the outer side wall of the accumulator tank. The annular air duct is welded on the strip-shaped reinforcing ribs. Air blowing pipe fittings are fixed on both sides inside the annular air duct. Jet ports matching the accumulator tank are uniformly arranged on the air blowing pipe fittings. A micro air pump is installed at one end of the annular air duct.

[0006] Preferably, the annular reinforcing ribs and the strip-shaped reinforcing ribs are both made of aluminum alloy, so that they can strengthen the accumulator tank and improve the anti-collision protection of the outer wall of the accumulator tank.

[0007] Preferably, rubber buffer layers are vulcanized and connected to the outer side walls of the annular reinforcing ribs and the strip-shaped reinforcing ribs, so that they can achieve better buffer protection for the outer wall of the accumulator tank.

[0008] Preferably, a protective rubber tray matching the energy storage airbag is suspended at the bottom inside the accumulator tank body, so that the protective rubber tray can be used to protect the energy storage airbag during expansion.

[0009] Preferably, a telescopic guide post is connected between the protective rubber tray and the accumulator tank body, and a spring is arranged between the telescopic guide post and the protective rubber tray.

[0010] Preferably, the material of the energy storage airbag is high-strength polyurethane.

[0011] Preferably, threaded assembly fittings matching the electric flow control valve are arranged at both ends of the hydraulic oil reserved through port, so that it is convenient to assemble the device with the liquid inlet pipe and the liquid return pipe on the corresponding hydraulic oil storage equipment through the two threaded assembly fittings.

[0012] Preferably, a filter screen is arranged inside the threaded assembly fitting, so that impurities in the hydraulic oil can be prevented from entering the inside of the energy storage hydraulic oil activity cavity and causing pollution.

[0013] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0014] (1). By installing an electric flow control valve and the like, the adjustable accumulator for automobiles optimizes its own performance. On the one hand, the user can fill nitrogen into the energy storage airbag inside the accumulator tank body through the nitrogen filling port. During this process, the pressure gauge can monitor the air pressure value of the nitrogen filled into the accumulator tank body in real time. When the preset value is reached, the user can stop inflating and use the manual control valve to close the nitrogen filling port. This makes the device convenient to adjust the air pressure of the energy storage airbag and optimizes its energy storage effect. On the other hand, the hydraulic oil inside the externally connected hydraulic oil storage structure will enter the energy storage hydraulic oil activity cavity only after the flow rate is regulated by the electric flow control valve. At this time, the hydraulic oil will compress the energy storage airbag to achieve the energy storage effect, and the flow rate and oil inlet time of the hydraulic oil entering the device can be regulated by the timer and the electric flow control valve respectively. After calculation and processing by the PLC controller, the volume of the hydraulic oil entering the device can be measured. When the preset safety value is reached, the PLC controller will control the electric flow control valve to close to avoid damage to the device caused by excessive oil inlet, improve safety, and is beneficial to extending the service life of the device;

[0015] (2) The adjustable accumulator for vehicle optimizes its own performance by installing an annular air duct, etc. When starting the micro air pump, the air body can be continuously and evenly blown towards the accumulator tank through two air blowing pipe fittings provided with air jet ports via the annular air duct. Through the air blowing treatment, it can not only dissipate heat and protect the accumulator tank, but also blow-dry and protect the outer wall of the accumulator tank. Without manual regular cleaning of the surface of the accumulator tank, it can ensure that it remains dry, clean, and avoid moisture and rust.

[0016] (3) The adjustable accumulator for vehicle optimizes its own performance by installing an annular reinforcing rib, etc. When the device is specifically used, on the one hand, an annular reinforcing rib and a strip-shaped reinforcing rib are evenly fixed on the outer side wall of the accumulator tank, and both the annular reinforcing rib and the strip-shaped reinforcing rib are composed of a copper alloy and rubber composite, which is beneficial to improving the structural strength and anti-collision protection of the accumulator tank. On the other hand, a protective rubber tray is connected to the bottom end inside the accumulator tank by a telescopic guide post and a spring. When the accumulator airbag expands, the anti-scratch effect of the protective rubber tray and the elastic buffering performance of the telescopic guide post and the spring can achieve a good protection effect.
