Embodiment 1

[0071] The vehicle brake booster provided by the embodiment of the present invention includes a housing, a pedal force input unit, a pedal force transmission unit, a support and guide unit, an electric power transmission unit, an electric power generation unit, a reset unit and a braking force output unit.

[0072] Such as Figure 1~4 As shown, the housing includes an upper cover 27, an intermediate housing 26 and a bottom housing 23 connected in sequence; the middle part of the upper cover 27 is provided with a through hole for the columnar input end of the brake master cylinder 28 to pass through, and the intermediate housing 26 Four bolt fixing holes 261 are arranged on the inner side wall (the bolt fixing holes 261 can not only connect but also carry force); It is fixed on the middle casing 26 together with the upper cover 27; the bottom casing 23 is fixedly installed on the vehicle through the booster fixing bolts 25; the bottom casing 23 is also provided with a connector...

Embodiment 2

[0105] Such as Figure 19 As shown, the difference between the present embodiment and the first embodiment is only that the pedal force transmission rod 7 and the pedal force transmission plate 8 are only in axial contact but not connected.

[0106] The working principle of this embodiment is the same as that of Embodiment 1.

Embodiment 3

[0108] Such as Figure 20 As shown, the difference between this embodiment and the first embodiment is only that the support return spring is arranged in the middle, and the pedal force support 13 and the electric power support 12 are reset at the same time.

Abstract

In order to solve the technical problem that potential safety hazards exist in an existing brake booster with a retardation recognition function, the invention provides a brake method capable of automatically and emergently braking under the retardation condition and a brake booster. A pedal force transmission rod and a pedal force transmission plate in a pedal force transmission unit are separately arranged in the axial direction; in an automatic emergency braking mode, when a foreign matter exists or the foot of a driver stretches into the bottom of the vehicle brake pedal, the movement of the pedal force transmission rod is blocked, so that the pedal force transmission plate is separated from the pedal force transmission rod, and the situation that the foot of the driver is pinched dueto continuous translation of the pedal force transmission rod or brake system components are damaged due to the firm foreign matter is avoided; meanwhile, during automatic emergency braking, due to the fact that the pedal force transmission plate can still translate under the action of electrodynamic force, the electrodynamic force transmission unit cannot be prevented from transmitting the electrodynamic force to implement braking operation, and potential safety hazards existing in an existing brake booster with a retardation recognition function are avoided.

Description

technical field [0001] The invention relates to a braking method and a brake booster capable of automatic emergency braking in the case of stagnation. Background technique [0002] A traditional vehicle brake booster includes a housing, a pedal force input unit, an electric power generating unit, a support and guide unit, a reset unit, a pedal force transmission unit, an electric power transmission unit, and a braking force output unit; the pedal force input unit is used for Receive the pedal force from the driver; the electric power generation unit is used to generate electric power; the support and guide unit is used to support the pedal force transmission unit and the electric power transmission unit in the housing, and ensure that the pedal force transmission unit and the electric power transmission unit It can only move in the axial direction; the reset unit is used to reset the pedal force transmission unit and the electric power transmission unit; the pedal force tran...
