Abstract
A multi-section electronic pointer comprises a multi-section connection pipe, a pointer head, and a circuit. The pointer head is arranged on the front of the first section of the multi-section connection pipe and connected to the circuit through a lead. A super capacitor or a rechargeable battery which is arranged inside the first section of the multi-section connection pipe is connected to the circuit as a power supply. The multi-section electronic pointer provided by the utility model and having multiple telescopic sections can be realized through a pull bar with a simple structure. The multi-section pluggable electronic pointer can be also realized in a relatively simple way. The contraction length of the electronic pointer is significantly shortened. Meanwhile, the electronic pointer is simple to manufacture. Furthermore, the pointer head contacting and triggering effects can be conveniently achieved thanks to the power supply and the circuit both arranged inside the first section of the connection pipe.
Description
Technical field
The utility model relates to a kind of electronic teacher pointer, especially a kind of more piece electronic teacher pointer for electronic whiteboard.
Technical background
Large-scale electronic whiteboard need use long electronic pen, or claims electronic teacher pointer (long epen or pointer epen).Front end at teacher's pointer need have transmitter to be used for the signal emission.But long teacher's pointer is not portable and transportation, so need be in that the time spent can not shorten.Prior art is to adopt two-layer nested metal pull bar structure, this structure is made of the telescopic antenna of inside and outside two-layer mutually insulated, the front end of internal layer pull bar has optical transmitting set, the end of outer pull bar fixedly has connector, there is the handle can cylinder lever connecting rod in addition, and drives transmitter by contact by inside and outside two-layer pull bar.All control assemblies and power supply are all in handle.When using, pull bar can be moved to so the longest, and not the time spent pull bar prosthomere is pushed deutomerite, realize telescopic electronic teacher pointer.The commercialization of this technology for many years.
The major defect of above-mentioned prior art is, owing to need two-layer pull bar, and it must not contact under any state mutually, therefore can't realize the above Tiebar structure of 2 joints, otherwise be easy to cause the inside and outside two-layer situation that is in contact with one another short circuit.Product generally is the telescopic forms of two joints at present, so still longer after the pull bar contraction, and inconvenience is carried.For example tensile elongation is 60 centimetres, still surpasses 30 lis after then shrinking, and is that then contracted length is longer more than 1 meter if require tensile elongation, so very inconvenient carrying.
Summary of the invention
The purpose of this utility model is the shortcoming that overcomes above-mentioned prior art, and a kind of more piece electronic teacher pointer is provided.
For achieving the above object, more piece electronic teacher pointer of the present utility model comprises more piece connecting pipe, teacher's pointer head, circuit, the teacher's pointer head is installed in the front end of described more piece connecting pipe first segment and has lead to be connected to described circuit, it is characterized in that, ultracapacitor or rechargeable battery are installed in described more piece connecting pipe first segment are connected to described circuit as power supply.Charge for convenience, charging socket can be set, charge in order to insert attaching plug.The end of its first segment also is equipped with charging socket and is connected to described circuit.
Adopted after the technique scheme, the more piece electronic teacher pointer that the utility model provides has such beneficial effect: owing to be provided with power supply in the first segment connecting pipe, therefore do not need from drawing current supply circuit in the handle to transmitter, so can realize the electronic teacher pointer of multi-joint telescoping with the pull bar of one deck ordinary construction, also can realize the electronic teacher pointer that more piece can patch comparatively simply, the contracted length of electronic teacher pointer is shortened greatly, make simple simultaneously.In addition, owing to concentrated power supply and circuit in the first segment connecting pipe, therefore can conveniently realize effects such as nib contact triggering.
Description of drawings
Fig. 1 is the structural representation of first embodiment of the present utility model;
Fig. 2 is the structural representation of second embodiment of the present utility model;
Among the figure: telescopic lever 1, teacher's pointer head 2, trigger switch 3, circuit 4, ultracapacitor 5, charging socket 6, the connecting pipe first segment 7 of plugging mode, the follow-up joint 8 of the connecting pipe of plugging mode.
Embodiment
Below in conjunction with drawings and Examples the utility model is further described.
Fig. 1 has provided the structural representation of specific embodiment of a kind of stretching structure of more piece electronic teacher pointer of the present utility model.Wherein telescopic lever 1 is a common telescopic antenna structure, and it has constituted described more piece connecting pipe; Teacher's pointer head 2 inside have infrared transmitting tube to link circuit 4, and it is fixed on the front end of trigger switch 3 and is connected to circuit 4; The other end of trigger switch 3 is fixedly mounted on the front end of first segment connecting pipe; Trigger switch 3 adopts existing trigger switch structure, and its signal output is connected to circuit 4; Charging socket 6 is connected to circuit 4, and ultracapacitor 2 also is connected to circuit 4.Charging socket 6 is Mini USB socket, so conveniently directly charges from the power taking of computing machine USB mouth.Outermost one joint of telescopic lever 1 can add one deck shell so that hold, but leaves opening at its end, after pull bar shrinks, can plug be inserted charging socket 6 by this opening and realize charging like this.
In the above-described embodiments, also can use the lightweight nonmetallic pipe, make telescopic lever as the charcoal fibre pipe, the similar fishing rod of structure can be realized long and lighter more piece electronic pen like this.
Fig. 2 is the structural representation of second embodiment of the present utility model; It and first embodiment difference are that the mode that has adopted more piece to patch realizes the prolongation of teacher's pointer.Wherein 7 is first segment connecting pipes, and 8 follow-up connecting pipes can have the identical follow-up connecting pipe 8 of more piece.First segment connecting pipe 7 can be pulled up during charging, charging plug be inserted charge then, during use the follow-up connecting pipe 8 of one joint be linked to each other with first segment connecting pipe 7, form long electronic teacher pointer thereby insert the follow-up connecting pipe 8 of more piece with the same manner again.
In addition, in order to realize complicated signal emission, as many push button signalling emissions, can also establish an optical receiver in the rear end of the first segment of described more piece connecting pipe, infrared receiving module for example is connected with a connector at the deutomerite end of described more piece connecting pipe, has a handle to link to each other with described pull rod coupling simultaneously, front end at handle has an optical transmitting set, and battery, button and circuit are arranged in the handle.Like this when the button of handle is pressed, signal is by above-mentioned optical transmitting set emission, if the inner leaded light better performances of described more piece connecting pipe, then light signal can be received by the optical receiver in the first segment connecting pipe by connecting pipe, thus the signal emission of control teacher's pointer head.
Same consideration also can replace above-mentioned optical receiver and optical transmitting set with Receiver Module and radiofrequency emitting module, realizes same function.This form is more suitable in nonmetallic long electronic teacher pointer, perhaps the bad situation of the light conductivity of connecting pipe.
In the above-described embodiments, described trigger switch can be the used pressure activated switch of pressure trigger luminous pen, also can be other better simply switch, and described circuit also may be the connection of simple Devices.Power supply also can be used rechargeable battery, and its advantage is that capacity is bigger.But that super capacitor has is light, environmental protection, the advantage fast of charging.
