Embodiment 1

[0082] A vehicle automatic emergency brake booster 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.

[0083] Such as figure 1 , Figure 9 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; the middle 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 bear force), the middle housing 26 can be manufactured by drawing molding, die-casting molding, injection molding and other processes; The fixing bolts 29 and the bolt fixing holes 261 are fastened together, and the brake master cylinder 28 and the upper cover 27 ar...

Embodiment 2

[0109] Such as Figure 14 As shown, the difference between the present embodiment and the first embodiment is only that the second elastic element 18 is arranged between the first elastic element 35 and the braking force output element A19, the second elastic element 18 is an annular structure, the first The elastic element 35 can pass through the second elastic element 18 to transmit the braking force to the braking force output element A19.

Embodiment 3

[0111] The difference between this embodiment and Embodiment 1 is only:

[0112] 1. The electric power support 12 and the pedal force support 13 do not share guide rails, but have their own guide rails, that is, the guide rail assembly includes electric power guide rails and pedal force guide rails;

[0113] 2. Both the electric power guide rail and the pedal force guide rail are concave, C-shaped or Ω-shaped in section (such as Figure 15 shown), and the return spring of the electric power support is installed in the electric power guide rail, and the return spring of the pedal force support is installed in the pedal force guide rail.

[0114] All the other structural forms are the same as in Embodiment 1.

Abstract

In order to solve the technical problem that when a motor of a traditional vehicle automatic emergency brake booster breaks down, large force needs to be paid for manual braking, the invention provides the vehicle automatic emergency brake booster. According to the invention, a double-support and two-side reset structure is adopted; the reset spring is only arranged on the electric power support;the electric power support and the pedal force support are both provided with the reset springs, when a motor of the vehicle automatic emergency brake booster breaks down, a driver does not need to overcome the elastic force of the reset springs of the electric power support during manual braking, and therefore the pedal force needing to be applied is smaller than the pedal force needing to be applied in the prior art.

Description

technical field [0001] The invention relates to a vehicle automatic emergency brake booster. Background technique [0002] A traditional vehicle automatic emergency 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 Used to receive the pedal force from the driver; the electric power generating 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 The transmission unit 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 transmission unit is used to transmit the ped...
