Description

Technical Field

[0001] This utility model relates to the field of automotive braking, and in particular to a vacuum assist system for automotive braking. Background Technology

[0002] For conventional gasoline-powered vehicles, the vacuum booster braking system relies on the engine's intake manifold for vacuum. Its working principle involves the engine drawing in a fuel-air mixture during its intake stroke within a very limited time. Simultaneously, due to structural and operational requirements, the air must pass through multiple "obstacles" such as the air filter, throttle body, and intake valves before entering the cylinders. This combination of limited time and obstructed passageways results in a pressure in the intake manifold lower than the external atmospheric pressure. This pressure difference between the intake manifold pressure and the external atmospheric pressure provides the vacuum pressure for the vacuum booster.

[0003] As living standards improve, users, seeking the ultimate driving experience, often use the left foot for braking and the right foot for accelerator. However, they find that under heavy acceleration, after several presses of the brake pedal, the pedal becomes stiff, leading to a lack of driving confidence. This is because as engine speed increases and intake air volume rises, the turbocharger's intervention prevents the intake manifold from forming a pressure differential, thus hindering the vacuum booster's ability to provide adequate vacuum.

[0024] Reference Figures 1 to 3In one embodiment of this utility model, a vacuum assist system for automobile braking includes an intake manifold 1, a vacuum booster 2, a vacuum controller 3, and a vacuum generating assembly 4. The intake manifold 1 is connected to the vacuum tube 21 of the vacuum booster 2. The vacuum controller 3 is connected to the vacuum tube 21 and is used to detect the vacuum level of the vacuum tube 21. The vacuum generating assembly 4 is disposed between the vacuum controller 3 and the vacuum tube 21 and is used to evacuate the vacuum tube 21. The vacuum controller 3 is also used to control the switching of the vacuum generating assembly 4.

[0025] An embodiment of the present invention provides a vacuum assist system for automobile braking. By setting up a vacuum controller 3 and a vacuum generating component 4, it can actively evacuate the vacuum tube 21 of the vacuum booster 2 when the engine cannot provide a vacuum for the vacuum booster 2, effectively improving the driving experience and ensuring smooth braking of the automobile.

[0026] The vacuum generating assembly 4 includes a vacuum pump 41, a power supply 42, and a relay 43. The vacuum pump 41 is connected to the vacuum tube 21. The relay 43 is located between the vacuum pump 41 and the power supply 42 and is connected to the vacuum controller 3. The vacuum controller 3 is used to control the opening and closing of the relay 43. The vacuum pump 41 can evacuate the vacuum tube 21, and the vacuum controller 3 can control the start and stop of the vacuum pump 41 by controlling the opening and closing of the relay 43. The vacuum generating assembly 4 also includes a one-way valve 44, which is located between the vacuum pump 41 and the vacuum tube 21. By setting the one-way valve 44, the vacuum tube 21, i.e., the vacuum booster 2, can be pressure maintained when the vacuum pump 41 fails. In this embodiment, the vacuum pump 41 is an electric vacuum pump, and the vacuum controller 3 is a dedicated controller for the vacuum system, which integrates a vacuum gauge and the output of the relay 43. Specifically, a TPG262 vacuum controller can be used, but it is not limited to this.

[0027] Two sets of vacuum generating components 4 are provided and are connected in parallel between the vacuum controller 3 and the vacuum tube 21. The two sets of vacuum generating components 4 can be used as needed. For example, when the vacuum controller 3 detects that the vacuum level of the vacuum tube 21 is higher than a preset threshold, one set of vacuum generating components 4 can be turned on first, or both sets of vacuum generating components 4 can be turned on directly. When the vacuum controller 3 detects that the vacuum level of the vacuum tube 21 is lower than a preset threshold, one set of vacuum generating components 4 can be turned off first, or both sets of vacuum generating components 4 can be turned off directly. The threshold here is the vacuum level, which is a negative value. In this embodiment, the two sets of working power supplies 42 can be the same power supply.

[0028] It also includes a mounting base 45, on which a sleeve 451 for accommodating a vacuum pump 41 is provided. The sleeve 451 consists of a positioning post 4511 and two arc-shaped plates 4512. The cross-section of the arc-shaped plates 4512 is "Ω". The positioning post 4511 is fixedly connected to the mounting base 45. One side of each of the two arc-shaped plates 4512 is fixedly connected to the positioning post 4511, and the other side of the two arc-shaped plates 4512 is connected by fastening bolts 4513. The arc-shaped plates 4512 are elastic plates. The structure of the sleeve 451 can adjust the tightness of the vacuum pump 41 located in the sleeve 451 by the fastening bolts 4513, or adapt to vacuum pumps 41 of different sizes, thereby improving the stability of the connection between the mounting base 45 and the vacuum pump 41. In this embodiment, the mounting base 45 is provided with two sleeves 451.

[0029] The inner wall of the arc plate 4512 is provided with sound insulation cotton 4514; by setting the sound insulation cotton 4514, the vacuum pump 41 can be wrapped up to protect it, and the noise generated by the vacuum pump 41 can be reduced to improve driving comfort.

[0030] The mounting base 45 is fixedly connected to the vehicle frame beam by bolts. The lower end of the mounting base 45 is provided with multiple shock-absorbing pads 4515. The shock-absorbing pads 4515 can reduce the vibration of the mounting base 45 and prevent the mounting base 45 from vibrating and making noise due to the operation of the vacuum pump 41, or from causing the connection between the mounting base 45 and the vehicle frame to loosen. In this embodiment, the shock-absorbing pads 4515 are made of rubber.

[0031] It also includes a control switch 5, which is connected to the vacuum controller 3; the control switch 5 is used to control the switching of the vacuum controller 3.

[0032] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
