Abstract
The utility model discloses a take on-vehicle charger of switch, including shell and bottom, install the drive plate in the shell, the electrode is connected to the drive plate rear end, and USB interface and touch switch board are connected to the drive plate front end, the shell front end is established and is corresponded complex opening and touch key with USB interface and touch switch board, and the touch switch board is attached in the touch key rear side, the bottom is connected and is fixed in port behind the shell, the electrode passes the bottom. Compared with the prior art, the utility model the advantage be: the utility model discloses an on-vehicle charger has the switch, and the convenience is controlled on-vehicle charger work through the mode of touch or not, avoids not pulling out on-vehicle charger for a long time and leads to on-vehicle charger thermal aging scheduling problem.
Description
Technical Field
The utility model relates to an on-vehicle charger especially relates to an on-vehicle charger of taking switch.
Background
The vehicle-mounted charger is a vehicle-mounted charger which is powered by a conventional automobile battery (12V for cars and 24V for trucks), and is widely used in the field of lithium battery charging of various portable and handheld devices. The existing vehicle-mounted charger is not provided with a switch, and is still inserted into a power taking port when not in use, if the vehicle-mounted charger is not pulled out for a long time, the vehicle-mounted charger is easily heated and aged, and potential safety hazards also exist in a circuit. Especially, after flameout, the power supply of the cigarette lighter is not cut off by some vehicles, and if the cigarette lighter is used for a long time, the electric quantity of the storage battery is extremely easy to consume, and the service life of the storage battery is shortened. Therefore, it is an urgent problem for those skilled in the art to develop a vehicle-mounted charger with a switch.
SUMMERY OF THE UTILITY MODEL
The utility model provides a solve above-mentioned not enough, provide a take on-vehicle charger of switch.
The above object of the present invention is achieved by the following technical solutions: the utility model provides a take on-vehicle charger of switch, includes shell and bottom, installs the drive plate in the shell, and the electrode is connected to the drive plate rear end, and USB interface and touch switch board are connected to the drive plate front end, the shell front end is established and is corresponded complex opening and touch key with USB interface and touch switch board, and the touch switch board is attached in touch key rear side, the bottom is connected and is fixed in the shell rear port, the electrode passes the bottom.
Further, the touch switch board is connected with a spring conductive part, and the connection rear end of the spring conductive part is connected to the driving board.
The utility model discloses well touch switch board's principle:
the switch board realizes the function of a touch switch through an induction capacitor, the induction capacitor exists between any two conductive objects, one key, namely one bonding pad and the ground can also form the induction capacitor, and under the condition that the surrounding environment is not changed, the value of the induction capacitor is a fixed and unchangeable tiny value. When a human finger is close to the touch key, the total induction capacitance value is increased by the induction capacitance formed by the induction capacitance parallel connection pad formed by the human finger and the ground and the induction capacitance formed by the ground. The capacitive touch key IC outputs a determination signal for switching display contents or closing after detecting that the value of the induction capacitance of the key changes.
Compared with the prior art, the utility model the advantage be: the utility model discloses an on-vehicle charger has the switch, and the convenience is controlled on-vehicle charger work through the mode of touch or not, avoids not pulling out on-vehicle charger for a long time and leads to on-vehicle charger thermal aging scheduling problem.
Drawings
Fig. 1 is a schematic structural diagram of the present invention.
Detailed Description
The present invention will be described in detail with reference to the accompanying drawings.
As shown in fig. 1, the vehicle-mounted charger with the switch comprises a housing 1 and a bottom cover 2, wherein a drive plate 3 is installed in the housing 1, the rear end of the drive plate 3 is connected with an electrode 4, the front end of the drive plate 3 is connected with a USB interface 5 and a touch switch plate 6, the front end of the housing 1 is provided with an opening 7 and a touch key 8 which are correspondingly matched with the USB interface 5 and the touch switch plate 6, the touch switch plate 6 is attached to the rear side of the touch key 8, the bottom cover 2 is fixedly connected to the rear port of the housing 1, and the electrode 4 penetrates through the bottom cover 2.
Further, the touch switch board 6 is connected to a spring conductive portion 9, and the rear end of the spring conductive portion 9 is connected to the driving board 3.
The utility model discloses well touch switch board's principle:
the switch board realizes the function of a touch switch through an induction capacitor, the induction capacitor exists between any two conductive objects, one key, namely one bonding pad and the ground can also form the induction capacitor, and under the condition that the surrounding environment is not changed, the value of the induction capacitor is a fixed and unchangeable tiny value. When a human finger is close to the touch key, the total induction capacitance value is increased by the induction capacitance formed by the induction capacitance parallel connection pad formed by the human finger and the ground and the induction capacitance formed by the ground. The capacitive touch key IC outputs a determination signal for switching display contents or closing after detecting that the value of the induction capacitance of the key changes.
The above only is the embodiment of the present invention, not limiting the patent scope of the present invention, all the equivalent structures or equivalent processes that are used in the specification and the attached drawings or directly or indirectly applied to other related technical fields are included in the patent protection scope of the present invention.
