Description

Technical Field

[0001] The utility model relates to a switch, in particular to a self-detecting passenger car brake light switch. Background Art

[0002] The brake light switch is mainly used to control the turning on or off of the brake light. The traditional brake light switch mainly includes a telescopic rod, one end of which is connected to a movable seat. By pressing the movable seat by stepping on the pedal, the contact assembly can be squeezed to control the on and off of the brake light signal, thereby realizing the switch control of the brake light. The defects of this brake light switch in actual use are: whether it is an emergency brake or a slow brake, as long as the brake pedal is stepped on, the brake light will light up, and the brake light will turn off after releasing it. In the actual driving process, the driver may brake suddenly and release the pedal again due to unskilled driving or some emergency situations. At this time, the brake light will be in a state of flickering, making it difficult for the following vehicle to actually understand the braking condition of the front vehicle, posing certain safety hazards.

[0017] As shown in the figure, the utility model discloses a self-detecting passenger car brake light switch, which has an outer shell. Specifically, the outer shell includes a lower shell 5 and an upper shell 2. A card-mounting block 3 is provided on the side wall of the upper part of the lower shell 5, and a card-mounting groove 4 that cooperates with the card-mounting block 3 is provided on the upper shell 2. A mounting frame 8 is provided in the outer shell, and the mounting frame 8 is provided with a first power connection plug 9 and a second power connection plug 10 that cooperate with each other, as well as a third power connection plug 18 and a fourth power connection plug 22 that cooperate with each other. A movable seat 6 is slidably provided in the outer shell, and a guide block 7 is extended from the outer side wall of the movable seat 6. A guide groove for inserting the guide block 7 is provided on the lower shell 5 to guide the movement of the movable seat 6. One end of the movable seat 6 is connected to the telescopic rod 1, and the telescopic rod 1 partially extends out of the outer shell and cooperates with the brake pedal. One end of the first power connection plug 9 located in the outer shell is provided with a first static contact 16, and the second static contact 18 is provided with a second static contact 16. The electrical plug 10 is provided with a second static contact 11 at one end located in the outer shell, and a conductive sheet 13 is movably provided in the mounting frame 8, and a first moving contact 15 and a second moving contact 12 are provided on the conductive sheet 13 to cooperate with the first and second static contacts, and a first elastic member 14 is pressed tightly at one end of the conductive sheet 13, and a conductive spring sheet 17 is provided on the movable seat 6, and a second elastic member 20 is pressed tightly at one end of the movable seat 6. When the movable seat 6 is pressed down, the conductive sheet 13 is first squeezed to separate the first and second moving contacts from the first and second static contacts, and then the conductive spring sheet 17 is contacted and matched with the third and fourth electrical plugs for electrical conduction. Furthermore, a first protrusion 19 that can contact and cooperate with the conductive spring sheet 17 is provided on the third electrical plug 18, and a second protrusion 21 that can contact and cooperate with the conductive spring sheet 17 is provided on the fourth electrical plug 22, so as to facilitate the contact and electrical conduction between the conductive spring sheet 17 and the third and fourth electrical plugs.

[0018] The working principle of the utility model is as follows: when the brake pedal is not stepped on, the second elastic member 20 will squeeze the movable seat 6 and lift it to a high position. At this time, the conductive sheet 13 is acted upon by the first elastic member 14, so that the first moving contact 15 on the conductive sheet 13 contacts the first static contact 16 on the first power plug 9, and the second moving contact 12 contacts the second static contact 11 on the second power plug 10, thereby realizing the connection and conduction between the first and second power plugs. When the driver steps on the brake pedal, the telescopic rod 1 is squeezed and the movable seat 6 is driven to descend and squeeze the conductive sheet 13 to descend, so that the first and second moving contacts are separated from the first and second static contacts, realizing the power off between the first and second power plugs, and feedback information is given to the controller to explain this. When the brake pedal is pressed, and as the movable seat 6 continues to descend, the conductive spring sheet 17 will be driven to contact the third and fourth power plugs respectively, so as to realize the power connection between the third and fourth power plugs and feedback information to the controller. The controller can obtain whether the braking is an emergency brake or a slow brake by analyzing the time difference between the power-off of the first and second power plugs and the power-on of the third and fourth power plugs. If it is an emergency brake, even if the brake pedal is released, the brake light will still be controlled to remain on for a certain period of time or the brightness of the brake light will be increased, or the double flash lights will be controlled to turn on at the same time, thereby providing sufficient warning to the rear vehicle. If it is a slow brake, as the brake pedal is released, the first and second power plugs will be powered on and the brake light will be controlled to be turned off.

[0019] This structure of the utility model, by providing the first and second power connecting plugs and the first and second static contacts and the moving contact on the conductive sheet, when the brake pedal is pressed to squeeze the telescopic rod and the moving seat, the first and second power connecting plugs will be disconnected to provide the first section of the signal, and then the conductive spring sheet is driven by the moving seat to connect with the third and fourth power connecting plugs to provide the second section of the signal. By analyzing the time difference between the changes of the two sections of the signal, it can be calculated whether the braking is an emergency braking or a slow braking state, and then the lighting state or brightness of the brake light can be controlled accordingly, so as to provide a more reliable and realistic braking situation to the rear vehicle, and effectively improve the safety of vehicle driving.
