Abstract
The invention discloses a hybrid vehicle engine hatch cover switch which comprises a T-shaped switch outer cylinder, wherein a big-end-up stepped through hole is arranged in the switch outer cylinder. The hybrid vehicle engine hatch cover switch is characterized in that a step is arranged at the middle-upper part of a T-shaped button, a return spring is sleeved on the button, the return spring and the button are together inserted into the switch outer cylinder, the lower end part of the button extends out from the lower end of the switch outer cylinder, the upper end of the return spring is abutted against the middle-upper part of the button, and the lower end is abutted against the step in the switch outer cylinder; the upper end part of an inserted sheet is matched and connected with the lower end part of the button, the lower end of the inserted sheet is connected with a socket connector, and the socket connector is connected with a controller. The invention avoids the occurrence of personnel safety accidents caused by electromotor starting due to operation failure when the hybrid vehicle engine hatch cover is opened.
Description
Technical field
The present invention relates to automobile component, be specifically related to hybrid vehicle engine hatch cover switch.
Background technology
In order to reduce CO
2Discharging, automobile vendor has developed the hybrid power system that uses a combustion engine and an electrical motor.Hybrid power frequently brakes at automobile, when starting to walk, the effect of energy-conservation pollution treatment can perform to ultimate attainment.Hybrid vehicle is with engine working area optimization, and efficient improves, and size reduction reduces drag losses and egress of heat, realizes idle stop; Produce the large torque of low-speed high-efficiency in electrical motor, the energy when braking and sliding can the automatic recovery; Existing automobile is produced system do not impact, do not need to be equipped with again Infrastructure.Therefore, the engine compartment cover of hybrid vehicle is not installed switch at present, at idling mode, if people's maloperation is arranged, very likely when opening engine compartment cover, with motor start-up, thereby causes injury to personnel.
Summary of the invention
The purpose of this invention is to provide hybrid vehicle engine hatch cover switch, it can avoid mixing electrical automobile when opening engine compartment cover, because of misoperation with motor start-up, the personal safety accident that causes.
Hybrid vehicle engine hatch cover switch of the present invention comprises the switch urceolus that is T-shape, is the through hole of up big and down small notch cuttype in the switch urceolus, it is characterized in that:
One middle and upper part that is the button of T-shape is provided with a step, overlap position spring once on button, insert in the lump in the switch urceolus, stretch out from the lower end of switch urceolus the bottom of button, the step of pull back spring upper end and button middle and upper part near ladder in, lower end and switch urceolus near;
The upper end of one inserted sheet and the bottom of button are connected, and the lower end of inserted sheet is connected with connector, and connector is connected with No. 41 PIN pin of controller (ECU).
Described hybrid vehicle engine hatch cover switch is characterized in that: cover has a locating bush at the middle part of switch urceolus, and switch urceolus bottom is passed the mounting hole at front shroud lock carriage middle part and external teeth lock washer and nut and is connected; Protruding front shroud lock carriage height is controlled by locating bush.
When engine compartment cover was opened, this this switch was in closure state, circuit and vehicle body ground connection when closed, pass to the ECU(controller with ground signalling by wire harness this moment), thereby cut off the actuating motor power supply, it can not be started; When engine compartment cover was closed, switch disconnected, and break signal is passed to EUC, and the prompting engine compartment cover is closed, and can use actuating motor.
The invention has the beneficial effects as follows: avoided hybrid vehicle when opening engine compartment cover, with motor start-up, caused the generation of personal safety accident because of misoperation.
Description of drawings
Fig. 1 is structural representation of the present invention.
Fig. 2 is that the present invention is arranged on the schematic diagram on the front shroud carriage.
Fig. 3 is the schematic diagram that the present invention is connected with ECU.
The specific embodiment
The invention will be further described below in conjunction with accompanying drawing.
Referring to Fig. 1 and hybrid vehicle engine hatch cover switch shown in Figure 3, comprise the switch urceolus 2 that is T-shape, be the through hole of up big and down small notch cuttype in the switch urceolus; One middle and upper part that is the button 1 of T-shape is provided with a step, overlap position spring 5 once on button, insert in the lump in switch urceolus 2, stretch out from the lower end of switch urceolus the bottom of button 1, the step of pull back spring 5 upper ends and button 1 middle and upper part near, lower end and the interior ladder of switch urceolus 2 near; The bottom of the upper end of one inserted sheet 6 and button 1 is connected, and the lower end of inserted sheet is connected with connector, connector and ECU(controller) No. 41 PIN pin be connected.
The concrete model of ECU is: 3600010-G27/3600010-G29/3600010-G32/3600010-G33(Chang'an product piece number).
Referring to Fig. 1 and Fig. 2, cover has a locating bush 7 at the middle part of switch urceolus 2, and mounting hole 9 and external teeth lock washer 3 that front shroud lock carriage 8 middle parts are passed in switch urceolus bottom are connected with nut 4; Protruding front shroud lock carriage height is controlled by locating bush.
When being in free state, this moment, engine compartment cover was opened, inserted sheet 6 contacts with switch urceolus 2 under pull back spring 5 power effects, be equivalent to the switch closure, switch ground connection, ECU end signal level drags down, and during prompting, engine compartment cover is opened, control actuating motor by ECU and can not work this moment, prevents injury to personnel;
When being in pressed status, on button 1, inserted sheet 6 leaves switch urceolus 2 to engine compartment cover due to Action of Gravity Field, is equivalent to switch and disconnects, and ECU end signal level changes, and points out present engine compartment cover to be in closed condition, and ECU controls actuating motor and allows to start.
