Abstract

The utility model discloses a car door closing device, which comprises a single chip, a vehicle speed sensor, an indication module, an input module, a control module and an electric source module; and the single chip is connected with the vehicle speed sensor, the indication module, the input module, the control module and the electric source module respectively. The car door closing device adopts a starting automatic door closing mode and has an indication reminding in the case of not or not completely closing the car door; in addition, the car door cannot be opened in the car driving process so as to ensure safety of driving a vehicle.

Description

The automobile closing device

Technical field:

The utility model relates to a kind of closing device, specifically is a kind of automobile closing device.

Background technology:

At present, the closing device of a lot of automobiles all adopts hand switch control, when the needs closed door, presses switch.There is certain potential safety hazard in this closing device; Especially for the bus of the frequent switch door of needs; Driver's labour intensity is bigger; If just starting under the situation about putting in place is not closed or do not closed to driver's inadvertent at car door, even car door is opened in maloperation in the process of moving, these bring hidden danger all can for passenger's safety.

The utility model content:

The utility model technical problem to be solved is, overcomes above-mentioned technological deficiency, and a kind of automobile closing device that when vehicle starting, can close the door automatically is provided, and this device can also avoid automobile maloperation in the process of moving to open car door.

The technical solution of the utility model is; A kind of automobile closing device is provided; Comprise single-chip microcomputer, vehicle speed sensor, indicating module, input module, control module, change-over switch, power module, said single-chip microcomputer is electrically connected with vehicle speed sensor, indicating module, input module, change-over switch, control module, power module respectively.

Adopt after the above structure compared with prior art; The utlity model has following advantage: adopt starting to close the door automatically; And not closing or do not close under the situation about putting in place at car door has indicating reminders, and automobile can't be opened car door in the process of moving in addition, to guarantee traffic safety.

As improvement, it also comprises change-over switch and hand switch, and said change-over switch is electrically connected with single-chip microcomputer, and said control module is electrically connected with hand switch.Design is manually closed door model and is closed door model automatically and close door model for these two kinds, when automatic pass door model breaks down or the driver thinks and can switch the dynamic model formula of turning round and stretching out the hand when being necessary to use manual pass door model.

As improvement, it also comprises buzzer, and said buzzer is electrically connected with single-chip microcomputer., will send by automobile hypervelocity alarm sound when surpassing setting speed.

Description of drawings:

Accompanying drawing is the circuit block diagram of the utility model embodiment.

The specific embodiment:

Below in conjunction with the accompanying drawing and the specific embodiment the utility model is described further:

As shown in the figure; A kind of automobile closing device; Comprise single-chip microcomputer, vehicle speed sensor, indicating module, input module, control module, power module, said single-chip microcomputer is electrically connected with vehicle speed sensor, indicating module, input module, control module, power module respectively.

The single-chip microcomputer model that adopts in the present embodiment is 89C52; Said vehicle speed sensor is connected with single-chip microcomputer and is used for transmitting GES; Said indicating module is connected unlatching or the closed condition that is used for indicating car door with single-chip microcomputer, indicating module comprises photo-coupler EL817, light emitting diode and 555 timers; Said input module is connected unlatching or the closed condition that is used for importing car door with single-chip microcomputer, said input module comprises the open the door travel switch and the travel switch of closing the door; The signal that transmits through single-chip microcomputer after said control module is connected with single-chip microcomputer is controlled the unlatching of car door or is closed, and said control module comprises relay, electromagnetic valve and rocker switch; Said power module provides power supply, comprises battery and two positive supply three-terminal voltage-stabilizing circuit X7805 and X7812.

As preferably, it also comprises change-over switch and hand switch, and said change-over switch is electrically connected with single-chip microcomputer, and said control module is electrically connected with hand switch.Said change-over switch is connected with single-chip microcomputer to be used for switching the unlatching of car door or to close to adopt manually closes door model or closes door model automatically; Said hand switch is connected with control module and is used for manually controlling the unlatching of car door or closing.Design is manually closed door model and is closed door model automatically and close door model for two kinds, when automatic pass door model breaks down or the driver thinks and can switch the dynamic model formula of turning round and stretching out the hand when being necessary to use manual pass door model.

As preferably, it also comprises buzzer, and said buzzer is electrically connected with single-chip microcomputer.Like this, when vehicle in the process of moving the speed of a motor vehicle surpass to set the speed of a motor vehicle time, single-chip microcomputer can send warning according to the GES control buzzer of input, reminds the driver to slow down and goes slowly, to guarantee traffic safety.

The operating principle of the utility model is following: the indicating status that single-chip microcomputer controls car door opening or cuts out according to the vehicle door status signal of input module; Promptly when input module input car door is in the signal of closed condition; The indicating module indication is normal, and light emitting diode is not luminous not to glimmer yet; When input module input car door is in the signal of opening, the lumination of light emitting diode of indicating module, and light emitting diode continues to glimmer when or the signal of closing the door not in place when input module input closing of the door; Light emitting diode does not continue flicker equally when input module has the signal input.The signal input that do not have described here is meant that the travel switch of input module breaks down.Simultaneously, vehicle speed sensor is input to single-chip microcomputer with GES, and single-chip microcomputer controls the unlatching of car door through control module or cuts out, and that is to say in the vehicle ' process to open car door, has only under the dead ship condition and just can open car door.Specifically, when GES is 0Km/h, can normally open or closed door; When GES during greater than 3Km/h; Single-chip microcomputer controls cutting out of car door according to the input signal of vehicle door status, that is to say that then single-chip microcomputer is not worked if vehicle door status has been closed condition; If vehicle door status also is in opening, then single-chip microcomputer is through the control module closed door.The above is the operating principle under the door model of automatic pass; Need to prove; Automobile all is set at and is in automatic pass door model in the ordinary course of things, has only when automatically closing that door model breaks down or the driver thinks and just need switch to manual pass door model when being necessary to switch.Manually closing under the door model, single-chip microcomputer is only controlled the indication of vehicle door status according to the input signal of vehicle door status, the unlatching of car door or close the control that does not receive single-chip microcomputer, and open this moment or closed door is all accomplished through hand switch.

Below only be described, but can not be interpreted as it is restriction claim with regard to the utility model preferred embodiment.Every equivalent structure or equivalent flow process conversion that utilizes the utility model manual and accompanying drawing content to be done includes within the scope of patent protection of the utility model.
