Abstract
An anti-collision alarm device for automobile backing comprises an alarm device, a switch contact and a circuit, wherein the switch contact is used for controlling the alarm device to work, and the circuit is connected between the switch contact and the alarm device. When the switch contact is closed under the action of external force, the alarm device gives an alarm sound, and the anti-collision alarm device is further provided with a substrate. A negative pressure sucking disc is arranged on the substrate, at least one elastic touch rod is arranged on the substrate, and a movable contact of the switch contact is arranged at the end, connected with the substrate, of the touch rod. A stationary contact corresponding to the movable contact is arranged on the substrate, a contact terminal is connected to the end of one end, away from the substrate, of the touch rod, and the outer surface of the touch terminal is coated with a soft material layer. When the contact terminal abuts against a fixed object, the touch rod drives the movable contact and the stationary contact at the ends of the touch rod to be closed in the stress deformation process. The device is simple in structure and allowed to be skillfully arranged at any position of an automobile body. The device gives an alarm through deformation of the elastic rod and is very convenient to use and low in cost.
Description
Technical field
It is auxiliary with collision prevention device that the utility model relates to a kind of reversing, specifically a kind of reversing collision-proof warning device.
Background technology
At present, on most automobile, all use and have Reverse Sensor, can find out intuitively the situation at car rear portion by Reverse Sensor, thereby reach the object of anticollision, but traditional Reverse Sensor is comparatively expensive, and installs, overhaul all comparatively loaded down with trivial details, most importantly in some comparatively narrow, dark regions, Reverse Sensor is not very practical, and therefore, urgent need will work out a kind of reversing collision-proof warning device of with low cost, simple type.
Utility model content
For solving the problems of the technologies described above, the purpose of this utility model provides a kind of reversing collision-proof warning device, and it is simple in structure, any position that is arranged on car body that can be dexterous, and this device is reported to the police by the distortion of elastic rod, very easy to use, and cost is lower.
The technical scheme that the utility model adopts is: a kind of reversing collision-proof warning device, comprise an annunciator and control the switch contact of this alarm work and connect the circuit between this switch contact and annunciator, when this switch contact is subject to External Force Acting closed, the annunciator sound that gives the alarm, also be provided with pedestal, on pedestal, be provided with negative pressure sucker, on pedestal, be at least provided with one and there is elastomeric feeler lever, the moving contact of described switch contact is arranged on the end that feeler lever is connected with pedestal, corresponding moving contact is provided with break back contact on pedestal, be connected with a contact at feeler lever away from the end of one end of pedestal, outside face parcel one deck soft material layer of described contact, in the time that contact props up fixed object, feeler lever drives the moving contact action of its end and break back contact to realize closed in stress deformation process.
Described annunciator is arranged on pedestal and forms integrative-structure with pedestal.
Described feeler lever is arranged on pedestal by elastic parts near one end of pedestal.
Described feeler lever is provided with many, many feeler levers towards direction all not identical.
The beneficial effects of the utility model are:
One, this device, by pedestal being adsorbed on to any position of car body, in reversing process, elastomeric feeler lever distortion, gives reversing reserved certain space, while being out of shape to a certain degree, moving contact and break back contact closure are moved and driven in its end, annunciator sounded and remind car owner, and this device integral structure is simple, cost is very low, and setting position dexterity, very easy to use.
Two, the feeler lever described in this device can be provided with many; by by the feeler lever of many towards different directions; each feeler lever is to a certain degree to drive switch contact closure to make annunciator sounding in distortion, therefore, can realize multi-aspect, omnibearing preventing collision protection.
Three, the other end of described feeler lever is provided with contact, can, by outside face parcel one deck soft material layer of contact, guarantee in reversing process, not scratch other car body surfaces, has greatly improved the result of use of this device.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 is that the utility model is arranged on the structural representation on car body.
Mark in figure: 1, annunciator, 2, pedestal, 3, feeler lever, 4, contact, 5, moving contact, 6, break back contact, 7, elastic parts.
The specific embodiment
As shown in the figure, a kind of reversing collision-proof warning device, comprise an annunciator 1, control the switch contact that this annunciator 1 works and connect this switch contact and annunciator 1 between circuit and the built-in power of powering to this annunciator 1, when this switch contact is subject to External Force Acting closed, annunciator 1 sound that gives the alarm, also be provided with pedestal 2, on pedestal 2, be provided with negative pressure sucker, on pedestal 1, be at least provided with one and there is elastomeric feeler lever 3, the moving contact 5 of described switch contact is arranged on the end that feeler lever 3 is connected with pedestal 1, corresponding moving contact 5 is provided with break back contact 6 on pedestal, be connected with a contact 4 at feeler lever 3 away from the end of one end of pedestal, outside face parcel one deck soft material layer of described contact 4, in the time that contact props up fixed object, feeler lever drives the moving contact action of its end and break back contact to realize closed in stress deformation process, annunciator sounding reminding car owner.
Further optimize, described annunciator 1 is arranged on pedestal 2 and forms integrative-structure with pedestal 1, and the warning device of integrative-structure can better be realized flexible setting, uses convenient.
Described feeler lever 3 is arranged on pedestal 2 by elastic parts 7 near one end of pedestal 2, for example: can be by Spring Card on pedestal, also can be connected on pedestal by thering is elastomeric silica gel, when feeler lever is in deformation process, may not can drive the moving contact of its end to move early stage, and in the time being out of shape to a certain degree, it overcomes after the elastic force of elastic parts, drive the moving contact of end move and realize closure, annunciator sounding reminding car owner with the break back contact on pedestal.
Described feeler lever 3 also can adopt the bar with telescopicing performance; this feeler lever can be provided with many as required; many feeler levers towards direction all not identical; by by the feeler lever of many towards different directions; each feeler lever is to a certain degree to drive switch contact closure to make annunciator sounding in distortion; therefore, can realize multi-aspect, omnibearing preventing collision protection.
Described annunciator herein, when closed about this part contact, by built-in power and circuit start annunciator sounding, this technology belongs to existing proven technique, is scheme well-known to those skilled in the art, repeats no longer one by one herein.
In addition, this device is a separate component structure, and its setting position is comparatively free, uses very flexibly, and as shown in Figure 2, this device can be adsorbed on tailstock portion, and the environment also can be as required with reversing time is rationally determined, better car body is realized to omnibearing protection.
