Description
Technical field
It the utility model is related to control box on a kind of cable with fall protection function.
Background technology
At present, the family of electric automobile charges uses AC charging mode more, and control box is most to be portable on its cable, directly
Connect the 220V alternating currents using alternating current.
AC socket is actually using such charging assembly in fixed position at the initial stage of construction in home electrical system
When, because many people of AC socket position problems charge for convenience, control box on cable can be placed on windowsill and desktop etc.
Use, easily fall.
And the electric automobile charging interval is longer at present, generally all charge at night, if control box causes after falling on cable
Short circuit, it is easy to trigger other dangerous, cause the loss of user's life and property.
The content of the invention
Deficiency the purpose of this utility model is to overcome more than, there is provided simple in structure, easy to use, the Ke Yijian of one kind
Self-acceleration state is measured, and can be when detecting that itself falls, breaking inner power supply, reduces the band of the generation of danger
Control box on the cable of fall protection function.
The purpose of this utility model is achieved through the following technical solutions：Controlled on a kind of cable with fall protection function
Box, including box body, are equipped with three axis acceleration sensing chip, microcontroller, control relay circuit and charge control in the box body
Communicating circuit, three axis accelerate sensing chip to be connected by SPI communication bus with microcontroller, are connected with the microcontroller
Control relay circuit, the control relay circuit are connected with power input, the output terminal and charge control of the power supply
Communicating circuit is connected with charging gun.
The utility model have the advantage that compared with prior art for：
It is simple in structure, it is easy to use, by using adopting for chip microprocessor analyzing and processing 3-axis acceleration sensing chip
Collect data, differentiate whether control box on cable is fallen, detect and fall generation immediately by relay breaking inner power supply, really
Protect internal control circuit before product contacts to earth and be in passive states, and electric short circuit protection is provided.
Brief description of the drawings：
Fig. 1 is the structure diagram of the utility model；
Figure label：Tri- axis of 1- accelerates sensing chip, 2- microcontrollers, 3- control relay circuits, 4- charging guns, 5- chargings
Communication control circuit.
Embodiment：
In order to deepen the understanding to the utility model, the utility model is made below in conjunction with embodiment and attached drawing further
It is described in detail, which is only used for explaining the utility model, does not form the restriction to scope of protection of the utility model.
As Fig. 1 shows the embodiment of control box on a kind of cable with fall protection function of the utility model：Including box
Body, three axis are equipped with the box body and accelerate sensing chip 1, microcontroller 2, control relay circuit 3 and charge control communication electricity
Road 5, three axis accelerate sensing chip 1 to be connected by SPI communication bus with microcontroller 2, be connected with the microcontroller 2 after
Electrical apparatus control circuit 3, the control relay circuit 3 are connected with power input, the output terminal and charge control of the power supply
Communicating circuit 5 is connected with charging gun 4.
The utility model can not only detect self-acceleration state, but also can break when detecting that itself falls
Internal electric source is driven, reduces the generation of danger, increases 3-axis acceleration sensing chip in control box control circuit on cable, uses list
Piece microprocessor analysis handle 3-axis acceleration sensing chip gathered data, using programmed algorithm differentiate cable on control box whether
Fall, detect and fall generation immediately by relay breaking inner power supply, it is ensured that internal control circuit before product contacts to earth
Passive states are in, so as to provide electric short circuit protection.
The another statement of applicant, the utility model illustrate the implementation method of the utility model and dress by above-described embodiment
Structure is put, but the utility model is not limited to the above embodiment, that is, does not mean that the utility model has to rely on above-mentioned side
Method and structure could be implemented.Person of ordinary skill in the field is it will be clearly understood that any improvement to the utility model, to this reality
With the addition of new selected implementation method equivalence replacement and step, selection of concrete mode etc., the utility model is all fallen within
Within protection domain and scope of disclosure.
The utility model is not limited to the above embodiment, it is all using structure similar with the utility model and its method come real
All modes of existing the utility model aim, within the scope of protection of the utility model.
