Abstract
The utility model provides an off-board additional antenna for a cosmetic mirror type induction key. The off-board additional antenna (30) is made of a conductive material, is connected with a circuit board (40) and extends towards a space outside the circuit board (40). By the off-board additional antenna (30), the influence (such as shielding and reflection) caused by metal objects and a mirror (20) of a cosmetic mirror on electromagnetic waves can be reduced, so that the circuit board (40) can normally transmit and receive radio signals. The cosmetic mirror type induction key also has two functions of the cosmetic mirror and the induction key. When carrying the cosmetic mirrors, girls carry the induction keys. If an automobile induction key is provided, a user can open an automobile door without taking an automobile key, and the key can be left in a pocket or a bag; and the automobile door can be unlocked and opened by the user by pressing a button on a handle of the automobile door. The off-board additional antenna is very convenient to use and is used quickly.
Description
Technical field
The utility model relates to a kind of antenna, specifically for a kind of cosmetic mirror-type induction key is that use, external antenna circuit board.
Background technology
Along with the development of radiotechnics, the induction key has been widely used in automobile and house door lock.Such as, automobile-used induction key (or being referred to as: exempt from key system), when your door opening, the induction key can be stayed in pocket or bag.
As everyone knows, key and vanity mirror be every Ms go out must with two items.If can combine vanity mirror and induction key, that will facilitate the Ms to carry, and avoid forgeing.
But the mirror on vanity mirror (coat of metal is arranged) and metal parts can affect (shielding and reflection etc.) electromagnetic transmitting and receiving.At present, generally respond to key and only be arranged on the built-in aerial (for example: using one section Copper Foil cabling on circuit board as antenna) on circuit board.In the time of in circuit board is installed to vanity mirror, just the possible transmitting/receiving wireless signal of telecommunication normally, also just can't normally realize responding to function of key.
Summary of the invention
The technical problem that the utility model solves is: the outer additional antenna of plate that a kind of cosmetic mirror-type induction key is used, it can reduce metal objects on vanity mirror and mirror to electromagnetic impact (shielding, reflection etc.), thereby guarantees that circuit board can the normal transmitting/receiving wireless signal of telecommunication.
In order to solve the problems of the technologies described above, the utility model is by the following technical solutions: the outer additional antenna of plate that a kind of cosmetic mirror-type induction key is used, the outer additional antenna of described plate is made by conductive material, circuit board is by its emission or receive radio signals, it is characterized in that: the outer additional antenna of described plate both was connected with circuit board, extended to again circuit board space in addition.
Because the outer additional antenna of described plate can extend to circuit board space in addition, we just can be by adjusting its trend, length and permanent position, avoid metal objects and mirror on vanity mirror, reduce metal objects and mirror to electromagnetic impact (shielding, reflection etc.).This just allows the circuit board can the normal transmitting/receiving wireless signal of telecommunication, also just makes cosmetic mirror-type induction key can completely possess vanity mirror and two kinds of functions of induction key.
The accompanying drawing explanation
The assembling schematic diagram that Fig. 1 is a kind of cosmetic mirror-type induction key described in the utility model.
The specific embodiment
Below for a more detailed description to the utility model by reference to the accompanying drawings with embodiment.The present embodiment is only the description to the utility model preferred forms, scope of the present utility model is not had to any restriction.
Embodiment:
As shown in Figure 1, described cosmetic mirror-type induction key is general main is comprised of the outer additional antenna (30) of plastic casing (10), mirror (20), circuit board (40) and plate.
The outer additional antenna (30) of plate that described cosmetic mirror-type induction key is used both was connected with circuit board (40), extended to again circuit board (40) space in addition, avoided mirror (20) as far as possible.
After whole cosmetic mirror-type induction key assembles, circuit board (40) will be close to mirror (20).
If there is no the outer additional antenna (30) of plate, the coat of metal on that mirror (20) can have a strong impact on the radio signal of sending on circuit board (40).
And, when having installed the outer additional antenna (30) of described plate additional, the radio signal of that circuit board (40) just can transmit and receive by the outer additional antenna (30) of plate.The outer additional antenna (30) of described plate can significantly reduce mirror (20) to electromagnetic impact, thereby allows the normally transmitting/receiving wireless signal of telecommunication of circuit board (40).
The outer additional antenna of plate that cosmetic mirror-type induction key described in the utility model is used, can reduce metal objects and mirror to electromagnetic impact (shielding, reflection etc.), thereby guarantee the normally transmitting/receiving wireless signal of telecommunication of circuit board, also just allow cosmetic mirror-type induction key intactly possess vanity mirror and two kinds of functions of induction key.
Claims (1)
1. a cosmetic mirror-type is responded to the outer additional antenna of plate that key is used, the outer additional antenna (30) of described plate is to be made by conductive material, circuit board (40) is by its emission or receive radio signals, it is characterized in that: the outer additional antenna (30) of described plate both was connected with circuit board (40), extended to again circuit board (40) space in addition.
