Abstract
The utility model relates to a protection device used for preventing a vehicle door from scratching by a coming vehicle at back part when opening the vehicle door, which mainly solves the defect that the vehicle door is easy to scratch by the coming vehicle at back part when a passenger gets off and opens the door. The utility model is characterized in that coils of a main power switch (K), a microswitch (JK), and a delay relay (JS) are connected in series between a positive and a negative direct-current power supplies. The positive and the negative power input ends of a backup radar (BT) are connected between the positive and the negative direct-current power supplies through make contacts of the delay relay (JS), and the make contacts are closed transiently and are opened in delaying time. The coil of a voltage relay (B) is connected between two direct-current voltage output ends of the backup radar (BT); after a normally open contact of the voltage relay (B) is connected in series with the coil of an electromagnetic lock (T), the normally open contact of the voltage relay (B) is connected between the positive and the negative direct-current power supplies. The utility model has the advantages of avoiding causing the vehicle door to scratch when the passenger opens the door, and protects the vehicle in mint state and ensures the passenger's safety.
Description
Technical field:
The utility model relates to a kind of protective device that is installed on the automobile, especially relate to a kind of be used to prevent car door when opening by the protective device of back car scratch.
Background technology:
When people take in automobile, often when needs are got off, can burst open car door and ignored to fall and have vehicle and sail just from behind, therefore car door can often take place be sailed the phenomenon of the vehicle scratch that comes, or even cause casualties by the back.For the solution of this problem, still there is not highly effective measure at present.
The utility model content:
Get off the passenger and sailed the deficiency of the automobile scratch that comes when opening the door easily after one's death in order to overcome existing automobile, the utility model provides a kind of automotive door scratch resistant safety device, and the scratch resistant safety device of this kind automotive door has the advantages that automatically car door to be locked when having automobile to sail after one's death.
The technical solution of the utility model is: the scratch resistant safety device of this kind automotive door comprises car door limiter, radar for backing car, total power switch, microswitch, time-delay relay, voltage relay and electromagnetic lock.Wherein, the coil of total power switch, microswitch, time-delay relay is connected in series between the positive and negative dc source, the positive-negative power input of radar for backing car is connected between the positive and negative dc source through the moving together contact of time-delay relay, this moving together contact moment closure, Time Delay Opening, the coil of voltage relay is connected between two dc voltage output ends of radar for backing car, the constant open contact of voltage relay be connected between the positive and negative dc source after the coil of electromagnetic lock is connected.
In addition, for make electromagnetic lock can electric back locking car door, can be sawtooth pattern with the alteration of form of the radula of car door limiter.
The utlity model has following beneficial effect: because after taking the scratch resistant safety device of automotive door of such scheme to send the signal that car is arranged after one's death at radar for backing car; can the automatic locking car door; thereby avoided the passenger when opening the door, to cause car door to be taken place, not only protected vehicle but also guaranteed passenger's safety by the consequence of scratch.
Description of drawings:
Accompanying drawing 1 is an electrical schematic diagram of the present utility model.
Accompanying drawing 2 is structural representations of car door limiter of the present utility model.
1-radar for backing car positive supply input among the figure, 2-radar for backing car negative supply input, 3-radar for backing car control positive voltage output end, 4-radar for backing car control negative voltage output, 5-car door limiter radula.
The specific embodiment:
The utility model is described in further detail below in conjunction with accompanying drawing:
As shown in Figure 1, the scratch resistant safety device of this kind automotive door comprises car door limiter, radar for backing car BT, and total power switch K, microswitch JK, time-delay relay JS, voltage relay B and electromagnetic lock T.Wherein, the coil of total power switch K, microswitch JK, time-delay relay JS is connected in series between the positive and negative dc source, the positive-negative power input of radar for backing car BT is connected between the positive and negative dc source through the moving together contact of time-delay relay JS, this moving together contact moment closure, Time Delay Opening, the coil of voltage relay B is connected between two dc voltage output ends of radar for backing car BT, the constant open contact of voltage relay B be connected between the positive and negative dc source after the coil of electromagnetic lock T is connected.Microswitch JK is installed on the attacker place of car door.
In addition, the shape of the radula 5 of existing car door limiter is improved, as shown in Figure 2, is changed into sawtooth pattern, like this when the coil of electromagnetic lock T get electric after, drive clamp and move down, clamp drops in the sawtooth of radula 5, car door firmly can be locked.
During actual the use, the driver closes total power switch K, and this protective device just is in running status.When automobile comes to a complete stop, the passenger prepares to get off when touching handle on the car door on the car, microswitch JK closure, the coil of time-delay relay JS gets electric, its moving together contact moment closure, at this moment, radar for backing car begins to detect, if there is this moment car to occur after one's death, then by output dc voltage between two dc voltage output ends of radar for backing car BT, it is electric that the coil of voltage relay B is got, thereby car door is locked in electromagnetic lock T action.Because the contact that the moving together contact of time-delay relay JS is opened behind the certain hour automatically for time-delay, thus when its after the arrival setting-up time is opened automatically, radar for backing car dead electricity, thereby electromagnetic lock dead electricity, car door just can smooth opening.
Utilize the scratch resistant safety device of this kind automobile, can the automatic locking car door, thus avoided the passenger when opening the door, to cause car door to be taken place by the consequence of scratch, not only protect vehicle but also guaranteed passenger's safety.
Claims (2)
1, the scratch resistant safety device of a kind of automotive door, comprise car door limiter, radar for backing car (BT), it is characterized in that: the scratch resistant safety device of described automotive door also comprises total power switch (K), microswitch (JK), time-delay relay (JS), voltage relay (B) and electromagnetic lock (T), wherein, total power switch (K), microswitch (JK), the coil of time-delay relay (JS) is connected in series between the positive and negative dc source, the positive-negative power input of radar for backing car (BT) is connected between the positive and negative dc source through the moving together contact of time-delay relay (JS), this moving together contact moment closure, Time Delay Opening, the coil of voltage relay (B) is connected between two dc voltage output ends of radar for backing car (BT), the constant open contact of voltage relay (B) be connected between the positive and negative dc source after the coil of electromagnetic lock (T) is connected.
