Description

Technical Field

[0001] The utility model relates to the technical field of remote controllers, in particular to a remote controller. Background Art

[0002] Existing remote controllers mainly include infrared remote controllers and Bluetooth remote controllers. Among them, for infrared remote controllers, since infrared has directivity and does not require any pairing and can directly control, but the emission angle is limited and it cannot penetrate walls; for Bluetooth remote controllers, they use the 2.4G frequency band. The emission angle of radio frequency is non-directional and in a broadcast mode, and peripheral devices will receive Bluetooth data. Therefore, usually, pairing needs to be carried out first, and the communication method is negotiated during pairing. When a Bluetooth device receives data from a Bluetooth remote controller, it first determines whether it is a paired device, and then responds to the commands of the remote controller. This method artificially increases the pairing process and increases the difficulty of use. Summary of the Utility Model

[0003] The utility model provides a remote controller that transmits wireless signals in a directional manner to start corresponding devices, simplifies the manual pairing process of Bluetooth, and is more convenient to use.

[0025] The technical solution of the present utility model will be clearly and completely described below in conjunction with the accompanying drawings. Obviously, the described embodiments are part of the embodiments of the present utility model, rather than all embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0026] In the description of the present utility model, it should be noted that the orientation or positional relationship indicated by the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc. is based on the orientation or positional relationship shown in the accompanying drawings. It is only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and thus cannot be construed as a limitation to the present utility model. In addition, the terms "first", "second", "third" are only used for descriptive purposes and cannot be construed as indicating or implying relative importance.

[0027] In the description of the present utility model, it should be noted that unless otherwise clearly specified and defined, the terms "installed", "connected", "connected" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the communication inside two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances.

[0028] Such as Figures 1-3As shown in the figure, an embodiment of the present utility model provides a remote control, which specifically includes a housing 1, a first circuit board 2, a Bluetooth chip 3, and a PCB directional antenna. The Bluetooth chip 3 is soldered on the first circuit board 2 and is used to emit signals. The PCB directional antenna 4 is installed between the inner side wall of the housing 1 and the first circuit board 2. The first circuit board 2 and the PCB directional antenna 4 are electrically connected, so that the signals emitted by the Bluetooth chip 3 are directionally emitted through the PCB directional antenna 4 (in the 2.4G band). The angle of radio frequency emission is directional, rather than diverging signals in a broadcast form. Therefore, only the Bluetooth devices facing the PCB directional antenna 4 will receive the Bluetooth signals, and the devices around this device will not receive the signals. Because the signal transmission direction is determined and the devices are determined and in one-to-one correspondence, the protocol installation between the two can be omitted, and the Bluetooth pairing process can be omitted. The device can be directly started when receiving the signal. Therefore, compared with the prior art, there is no need to add the so-called artificial Bluetooth pairing process before use due to the difference in communication protocols, and the signal can be directly transmitted, making the remote control method of the device simpler. Moreover, the advantage of using a PCB board directional antenna is that it occupies less space, has a low cost, does not require separate assembly of an external antenna, can be directly installed in the housing 1, and is not easily touched and damaged. Specifically, the PCB directional antenna 4 is provided with a radio frequency interface 7, and is electrically connected to the first circuit board 2 through the radio frequency interface 7. Specifically, the application scenarios of the remote control in this embodiment can be Bluetooth lamps, aisle lights, induction lights, etc. in a parking lot.

[0029] Among them, the first circuit board 2 and the PCB board directional antenna 4 can be installed in the housing 1 by screws. A clamping groove can be set in the housing, and the first circuit board 2 and the PCB board directional antenna 4 can be clamped into the clamping groove.

[0030] Preferably, the PCB directional antenna 4 adopts a Yagi antenna structure, which has good directivity: it only receives and sends signals in a specific direction, avoiding signal interference and noise; high gain: the design of the Yagi antenna provides an excellent gain, which can increase the intensity of the antenna signal, thereby expanding its coverage range and reception range; strong stability. In this embodiment, the bottom width dimension of the PCB directional antenna 4 is 5.9 cm, the top width dimension is 3.9 cm, and the length is 12 cm.

[0031] Among them, the radiation angle of the signal of the PCB directional antenna is 20 degrees - 40 degrees. After the signal is radiated, it can not only transmit signals with Bluetooth devices within the target range, but also avoid excessive radiation angle, resulting in connection with other Bluetooth devices.

[0032] Preferably, a button 5 is provided on the outer shell 1. The button 5 is used to touch the contact of the first circuit board 2. The button 5 is divided into multiple instruction keys, which are set according to specific situations, and a corresponding button 5 detection circuit (prior art) is set on the first circuit board 2. Moreover, an indicator light 6 is also provided on the outer shell 1. The indicator light 6 is located at the front end of the remote control. The direction pointed by the front end of the remote control is the direction pointed by the PCB directional antenna 4. The indicator light 6 is connected to the first circuit board 2 through an existing circuit interface. When an instruction is sent through the instruction key, the Bluetooth chip 3 emits a 2.4G radio frequency signal through the PCB directional antenna 4, and the corresponding indicator light 6 also lights up, so as to give a reminder to the operator that the radio frequency signal has been emitted. Moreover, in order to make the direction of the PCB directional antenna 4 more clear, a pointing arrow can be set on the upper end face of the outer shell 1, that is, beside the indicator light 6, as a direction mark.

[0033] In order to make the power consumption of the entire remote control last longer, the button 5 also includes a power-on / off key. When the remote control is not in use, the first circuit board 2 is powered off and the remote control is powered off through the power-on / off key, saving electric energy for long-term use. When the remote control is in use, the first circuit board 2 is powered on and the remote control is powered on through the power-on / off key, and it can be used.

[0034] Preferably, the Bluetooth chip adopts version 4.0 or above. Different from the previous Bluetooth 2.0 and 3.0, the Bluetooth chip of version 4.0 and above has lower power consumption, longer and more stable transmission. Compared with the previous ones, the power consumption of Bluetooth 4.0 is reduced by more than 90%.

[0035] Specifically, it further includes a power supply device. The power supply device is installed in the outer shell 1 and is electrically connected to the first circuit board 2 through a power supply interface on the first circuit board 2 to provide electrical energy for the Bluetooth chip 3, the indicator light 6 and the PCB directional antenna 4. The power supply device can be a storage battery. Preferably, a USB interface can be set at the outer shell 1. The USB interface is provided with a charging circuit, and the storage battery can be charged through the USB interface.

[0036] The above embodiments are only the preferred embodiments of the present invention and cannot be used to limit the protection scope of the present invention. Any non-substantial changes and substitutions made by those skilled in the art based on the present invention belong to the protection scope required by the present invention.
