Abstract

An apparatus for controlling energy feedback, a braking system and a vehicle are disclosed. The apparatus includes a housing; an actuating assembly, received in the housing and movable back and forth between a first position and a second position along an axial direction of the housing; a first control member for a stop lamp, received in the housing and configured to trigger the stop lamp to be turned on or off along with a back-and-forth movement of the actuating assembly; and a second control member for energy feedback, at least partially received in the housing. The control member for the energy feedback is configured to acquire a braking depth signal of a brake pedal in real time based on the back-and-forth movement of the actuating assembly, and control the energy feedback based on the braking depth signal.

First claim

What is claimed is:

1 . An apparatus for controlling energy feedback, comprising:
a housing; an actuating assembly, received in the housing and movable back and forth between a first position and a second position along an axial direction of the housing; a first control member for a stop lamp, received in the housing and configured to trigger the stop lamp to be turned on or off along with a back-and-forth movement of the actuating assembly; and a second control member for energy feedback, at least partially received in the housing; wherein the second control member for the energy feedback is configured to acquire a braking depth signal of a brake pedal in real time based on the back-and-forth movement of the actuating assembly, and control the energy feedback based on the braking depth signal.

2 . The apparatus of claim 1 , wherein the second control member for the energy feedback comprises:
a magnetic field generating portion, fixed to the actuating assembly, movable synchronously along with the back-and-forth movement of the actuating assembly, and configured to generate a magnetic field; a Hall sensor, fixed on one side of an inner wall of the housing that is adjacent to the magnetic field generating portion, and configured to detect a change in strength of the magnetic field around the Hall sensor and output a real-time voltage signal; and a controller, electrically connected to the Hall sensor and a motor, and configured to convert the real-time voltage signal into the braking depth signal and control the energy feedback in real time based on the braking depth signal.

3 . The apparatus of claim 2 , wherein the magnetic field generating portion comprises a first magnet and a second magnet spaced apart from each other; the first magnet and the second magnet are successively disposed in a direction from the second position toward the first position along the axial direction of the housing;
when the actuating assembly is at the first position, a center of the first magnet is aligned with a center of the Hall sensor; while the actuating assembly is at the second position, a center of the second magnet is aligned with the center of the Hall sensor.

4 . The apparatus of claim 2 , further comprising a holder sleeved on a periphery of the actuating lever; wherein a receiving hole configured to receive the magnetic field generating portion is defined in the holder.

5 . The apparatus of claim 1 , wherein the second control member for the energy feedback comprises:
a movable portion, fixed to the actuating assembly and movable synchronously with the back-and-forth movement of the actuating assembly; a laser sensor, fixed on an inner wall of the housing, and configured to detect and output a real-time distance signal of the movable portion; wherein the real-time distance signal is configured to indicate a real-time distance between the movable portion and the laser sensor; and a controller, electrically connected to the laser sensor and a motor, and configured to convert the real-time distance signal into the braking depth signal and control the energy feedback based on the braking depth signal.

6 . The apparatus of claim 1 , wherein the actuating assembly comprises:
an actuating lever, received in the housing; a first elastic member, expandable and compressible along the axial direction of the housing; wherein one end of the first elastic member abuts against the housing, and the other end of the first elastic member abuts against the actuating lever; and a second elastic member, expandable and compressible along the axial direction of the housing; wherein the second elastic member is sleeved on the first elastic member; one end of the second elastic member abuts against the housing; the other end of the second elastic member abuts against the actuating lever in a condition that the actuating lever is at the first position, and moves to a position at which the stop lamp is turned on by the first control member for the stop lamp in a condition that the actuating lever is at the second position; a length of the second elastic member is less than a length of the first elastic member.

7 . The apparatus of claim 6 , wherein the first control member for the stop lamp comprises:
a first stationary contact, fixed in the housing; a first movable contact, fixed on the second elastic member; wherein the first movable contact is movable back and forth along with an expansion and compression of the second elastic member, such that the first movable contact is capable of being in contact with or separated from the first stationary contact; and a normally open signal terminal, electrically connected to the first stationary contact.

8 . The apparatus of claim 7 , wherein the first control member for the stop lamp further comprises:
a second stationary contact, fixed in the housing; a second movable contact, fixed on the actuating assembly; wherein the second movable contact is slidable back and forth along the second stationary along with the back-and-forth movement of the actuating assembly; and a normally closed signal terminal, electrically connected to the second stationary contact.

9 . The apparatus of claim 6 , wherein the housing comprises:
a base, comprising:
a first shell, opened at one end;
a second shell, connected to the first shell; and
a connecting plate, connected between the first shell and the second shell, and configured to separate the first shell from the second shell; wherein the first elastic member and the second elastic member are respectively fixedly connected to the connecting plate; and
a cover, disposed on the base; wherein the base and the cover cooperatively define a receiving space; the actuating assembly, the first control member for the stop lamp and the second control member for the energy feedback are received in the receiving space.

10 . The apparatus of claim 9 , wherein the cover comprises:
a cover body, disposed on the first shell and abutting against the connecting plate; and a hollow guide portion, extending from the cover body in a direction away from the connecting plate; wherein the actuating lever is at least partially disposed in the guide portion.

11 . The apparatus of claim 9 , wherein the housing further comprises a first guide post and a second guide post extending from the connecting plate in a direction toward the actuating assembly; the second guide post is sleeved on an outer side of the first guide post; a length of the second guide post is less than a length of the first guide post;
wherein the first elastic member is located between the first guide post and the second guide post, while the second elastic member is sleeved on the second guide post.

12 . A braking system, comprising:
