Description

Technical Field

[0001] The utility model relates to the technical field of Bluetooth-to-infrared transceiver devices, and in particular to a low-power Bluetooth-to-infrared transceiver device. Background Art

[0002] In recent years, smart home has become a hot industry, with many smart home products appearing on the market. Among them, wireless-to-infrared remote control devices are an important part of smart home systems. However, the wireless-to-infrared remote control devices currently on the market have many shortcomings.

[0003] After searching, I found prior art (publication number: CN204375156U), which describes "an ultra-low-power learning Bluetooth-to-infrared remote control device, relating to the field of smart home technology. The device comprises a circuit board housing and a universal positioning hose connected to the circuit board housing. The circuit board housing houses an MSP430 series ultra-low-power single-chip microcontroller, which is connected to an ultra-low-power Bluetooth 4.0 module, a battery voltage acquisition circuit, a button battery module, an infrared transmitting circuit, and an infrared receiving circuit. This utility model overcomes the shortcomings of existing wireless-to-infrared modules by significantly reducing power consumption using ultra-low-power components. The universal positioning hose allows for easy alignment of the infrared transmitter head with the appliance being remotely controlled. The device is powered by a button battery, and the battery voltage is monitored via a battery voltage acquisition circuit. The device uses two methods: learning the infrared code of the appliance remote control via the infrared receiver head and setting the infrared code via a mobile phone. This makes the device applicable to all infrared remote-controlled appliances."

[0004] Although the Bluetooth-to-infrared remote control device in the prior art improves the installation and use flexibility of the device, it still has some shortcomings: the existing Bluetooth-to-infrared remote control device is generally a box structure with an antenna, lacks a fixed structure between the table, and the internal circuit board is generally fixedly installed inside the box, which makes it easy for the internal electrical components to fall and be damaged by accidental contact. Secondly, although it has a low power consumption effect, without effective heat dissipation, it will still cause the internal temperature to be too high, which in turn leads to poor safety and stability in use.

[0021] Reference Figures 1 to 4As shown, the utility model provides a low-power Bluetooth to infrared transceiver device, comprising: a device housing 1, an anti-collision corner 11 is bonded to the outer corner of the device housing 1, and a transmitting antenna 12 and a receiving antenna 13 are connected to the upper end of the device housing 1, a fixing component 2 is installed on the outer wall of the device housing 1, and the fixing component 2 includes a screw plate 22, and a pressure plate 24 is provided on the lower side of the screw plate 22, and an upper heat dissipation hole 14 and a lower heat dissipation hole 17 are respectively opened on the upper and lower shell walls of the device housing 1, and a waterproof breathable membrane 15 is installed inside the upper and lower sides of the device housing 1. An upper fan 16 and a lower fan 18 are installed on the wall respectively, and the control main board 4 is located between the upper fan 16 and the lower fan 18. A shock-absorbing plate 3 is provided inside the device shell 1, and the control main board 4 is installed on the upper end of the shock-absorbing plate 3. A micro control unit chip 42 and a low-power Bluetooth to infrared module 45 are installed on the upper side of the control main board 4. A power module 41, an infrared transmitting circuit 44 and an infrared receiving circuit 43 are also installed on the upper end of the control main board 4, and the power module 41 is set as a lithium electronic button battery. The infrared receiving circuit 43 is electrically connected to the receiving antenna 13, and the infrared transmitting circuit 44 is electrically connected to the transmitting antenna 12.

[0022] In this embodiment, the device housing 1 and the inner and outer components constitute the main structure of the low-power Bluetooth-to-infrared transceiver device involved in this application.

[0023] Specifically, two handle threaded rods 21 are connected to the screw plate 22, so that the fixing stability of the device housing 1 is enhanced, and at the same time, the opposite side of the pressure block 23 and the pressure plate 24 is set as a rubber surface.

[0024] Specifically, the upper fan 16 and the lower fan 18 have the same blowing direction and are both configured to blow upward, thereby strengthening the air flow on the upper and lower sides of the control mainboard 4 and improving the heat dissipation effect.

[0025] Specifically, the microcontroller chip 42 and the low-power Bluetooth to infrared module 45 are configured as main components of a low-power Bluetooth to infrared transceiver device in the prior art.

[0026] As a preferred embodiment, by providing a waterproof and breathable membrane 15, not only a waterproof and breathable effect is achieved, but also a dustproof effect is achieved, thereby preventing dust from entering the device housing 1 through the heat dissipation holes and contaminating the control mainboard 4.

[0027] like Figure 1 and Figure 2As shown, the anti-collision corner 11 is set as an L-shaped structure made of rubber material, and the anti-collision corner 11 is bonded to the outside of the eight corners of the device housing 1, the screw plate 22 and the pressure plate 24 are arranged in parallel on the same side of the device housing 1, and the screw plate 22 is screwed with a handle threaded rod 21 inside, and the lower end of the handle threaded rod 21 is rotatably connected to a pressure block 23, and four guide columns 31 are respectively slid through the four corners of the shock-absorbing plate 3, and two independent springs 32 are sleeved on the outside of each guide column 31, and the two springs 32 are respectively located on the upper and lower sides of the shock-absorbing plate 3.

[0028] Specifically, the electronic components on the control main board 4 are electrically connected through a welding circuit, while the connection with the two outer antennas is made with soft wires, thereby preventing the shaking of the shock absorbing plate 3 from causing damage to the front side where the hard wire connection exists.

[0029] As a preferred embodiment, by providing the guide column 31 and the spring 32 , the shock absorbing plate 3 is suspended inside the device housing 1 , and elastic protection effects are provided above and below the shock absorbing plate 3 .

[0030] During use, the fixing assembly includes a rotary handle, a threaded rod, a screw plate, a pressure plate and a pressure block, so that the device casing can be clamped on the outer edge of a table near an electrical appliance, or the lower edge of an electrical appliance (TV), thereby achieving a stable fixation effect, and the infrared rays emitted during operation can be accurately received by the electrical appliance. In addition, the anti-collision corners set at the corners of the device casing can protect the device casing when it is accidentally touched and dropped. At the same time, the shock-absorbing plate, the guide column and the spring can achieve a buffering protection effect on the control motherboard after colliding with the ground when it falls. The heat dissipation holes opened on the upper and lower sides of the device casing and the waterproof and breathable membrane inside the heat dissipation holes can achieve a waterproof, dustproof and breathable heat dissipation effect on the inside of the device casing. At the same time, the upper fan and the lower fan can accelerate the air flow inside the device casing, thereby dissipating the heat generated by the electrical components on the control motherboard in time, improving the heat dissipation effect of the device and ensuring the safety and stability of use.

[0031] The low-power Bluetooth to infrared transceiver device of the utility model can effectively solve the problem that the existing Bluetooth to infrared remote control device lacks fixation and anti-collision protection effects, and has poor internal heat dissipation effect. It achieves the addition of fixation and anti-collision protection effects to the existing low-power Bluetooth to infrared transceiver device technology on the basis of the existing low-power Bluetooth to infrared transceiver device technology, and at the same time improves the internal heat dissipation effect as well as the waterproof and dustproof effects.
