Description

Technical Field

[0001] The present invention relates to the technical field of lamp control, and in particular to an external Bluetooth module and a lamp wireless control device. Background Art

[0002] Smart lamps refer to lamps that are connected to the control end through the Internet of Things technology to achieve wireless control. At present, lamps are generally connected to remote control devices through Bluetooth. The Bluetooth part of existing lamps generally includes a Bluetooth chip and an antenna. The Bluetooth chip is integrated in the power module of the lamp, and the antenna is built-in. The above-mentioned scheme has the following shortcomings: if the Bluetooth chip is integrated in the power module, the power module is shielded by a metal shell around it. In order to ensure the normal transmission of the Bluetooth signal, an opening must be made in the metal shell, which reduces the dust and water resistance. If the user does not need to use the wireless function, the user's purchase cost will increase. When the antenna is built-in, since the power module and the Bluetooth chip are located inside the lamp cover, the installation position cannot be changed. When the Bluetooth transmission direction is blocked or interfered by the magnetic field caused by high-power electrical appliances, the built-in antenna cannot adjust the Bluetooth position and direction according to the use environment, and the flexibility is poor. Summary of the invention

[0003] In order to overcome the deficiencies of the prior art, the purpose of the present invention is to provide an external Bluetooth module, which solves the problem that the Bluetooth module cannot be installed independently and avoids the problem that the antenna is built-in and the installation position and signal direction cannot be adjusted according to the use environment.

[0004] The technical solution adopted by the present invention is as follows: An external Bluetooth module comprises a Bluetooth module consisting of a PCB board, a Bluetooth chip and an antenna. The Bluetooth module is separated from a power module. The Bluetooth chip and the antenna are integrated on the PCB board. The PCB board is installed in a non-metallic shell. The PCB board is connected to the power module through a connecting line.

[0005] Compared with the prior art, the present invention has the following beneficial effects: 1. Separate the antenna and Bluetooth chip from the power module. According to user needs, an external Bluetooth module can be selectively installed. If the Bluetooth function needs to be added, the Bluetooth module can be purchased separately without replacing new lamps with Bluetooth control. 2. After the external Bluetooth module is separated, the antenna is inside the shell and is not easily affected by the external environment. In addition, since the installation position and direction of the external Bluetooth module can be adjusted, it can avoid metal objects blocking the transmission direction and magnetic field interference, thus ensuring stable signal transmission.

[0006] As a preferred embodiment of the present invention, the power module is located inside the lamp cover, and the Bluetooth module is located outside the lamp cover and is installed on a lamp stand or a building wall.

[0007] Beneficial effect: The position between the power module and the lamp cover is fixed. By setting the Bluetooth module on the outside of the lamp, the distance between the Bluetooth module and the power module is only limited by the length of the connecting line. Therefore, it can be installed on the original lamp stand or on the wall of an accessory to avoid being affected by the use environment, making the installation of the Bluetooth module more flexible.

[0008] As a preferred embodiment of the present invention, the antenna is a ceramic antenna.

[0009] Beneficial effects: Ceramic antennas can achieve efficient signal transmission in a smaller size, and are suitable for integration in space-constrained devices, significantly reducing the overall size. Ceramic antennas can be directly soldered on PCB boards, with a relatively simple design and cost savings.

[0010] As a preferred embodiment of the present invention, the shell includes an upper shell and a lower shell, the upper shell is snap-connected with the lower shell, the outer wall of the upper shell is close to the inner wall of the lower shell, the PCB board is installed on the inner top surface of the upper shell, one end surface of the antenna is close to the PCB board, and the other end surface is close to the inner bottom surface of the lower shell, and the three side walls of the antenna are close to the corresponding inner wall of the upper shell.

[0011] Beneficial effects: The upper shell and the lower shell are tightly fitted, and the side walls of the two are offset against each other, making the whole more stable. Since the ceramic antenna mainly includes a ceramic substrate, the ceramic substrate is square. Before assembly, the ceramic substrate is located on the top of the upper shell. After assembly, the upper shell can limit the three side walls of the ceramic substrate. When the external Bluetooth module is impacted, the force is more uniform, making it difficult for the welding points on the bottom of the ceramic substrate to detach from the PCB board.

[0012] As a preferred embodiment of the present invention, a threaded sleeve is vertically provided on the upper portion of the upper shell, and a nut is screwed on the threaded sleeve; a through hole is opened in the threaded sleeve of the upper shell, and the connection port is arranged in the through hole.

[0013] Beneficial effects: 1. Through the above structure, two installation methods can be realized. First, when there is a through slot or through hole larger than the outer diameter of the threaded sleeve on the frame of the lamp, the upper shell can be pushed in from bottom to top, the threaded sleeve passes through the through slot or through hole, and then the threaded sleeve passing through the through slot or through hole is locked by a nut. Second, when there is a threaded hole matching the threaded sleeve on the frame, it can be directly screwed into the threaded hole; 2. The threaded sleeve not only plays the role of installation, but the connection port is located inside the threaded sleeve, which can play a certain role in waterproofing and dustproofing the wiring part.

[0014] As a preferred embodiment of the present invention, a card slot is vertically provided on the outer wall of the upper shell, a first positioning slot is provided below the card slot, and an elastic card block is provided on the inner wall of the lower shell. During assembly, the elastic card block can slide along the first positioning slot and then engage with the card slot.

[0015] Beneficial effect: When only the card slot is set for assembly, during the process of inserting the upper shell into the lower shell, the elastic card block first contacts and squeezes the outer wall of the upper shell. At this time, it is more laborious to continue pressing into the lower shell. Therefore, by setting the first positioning groove, it not only plays a positioning role before assembly, but also the elastic card block can slide effortlessly along the first positioning groove during assembly, shortening the extrusion stroke of the elastic card block during assembly, and the insertion process is easier.

[0016] As a preferred embodiment of the present invention, second positioning grooves are opened on both sides of the upper shell, and a positioning plate is horizontally provided in the lower shell. The positioning plate is engaged in the second positioning groove and is close to the side wall of the ceramic antenna. The Bluetooth chip is located on the other side of the positioning plate.

[0017] Beneficial effect: By setting the second positioning groove to engage with the positioning plate, the stability of the overall structure is increased, and one side of the positioning plate limits one side of the ceramic antenna, and in conjunction with the upper shell, the four sides of the ceramic antenna can be limited, making the overall structure more stable; The positioning plate can also hold the Bluetooth chip on the PCB tightly, preventing it from shaking when hit, further improving stability.

[0018] As a preferred implementation manner of the present invention, the Bluetooth chip adopts an NRF Bluetooth chip.

[0019] Beneficial effects: NRF Bluetooth chip has the advantages of low power consumption, high performance and low development difficulty.

[0020] The power module is provided with a communication interface, which is connected to the Bluetooth chip via TX and RX pins.

[0021] Beneficial effect: By setting the communication interface, the communication between the Bluetooth chip and the power module and the detachable connection are realized, which is convenient for disassembly and assembly.

[0022] The present invention also provides a wireless control device for lamps, which adopts the external Bluetooth module described above, is more flexible in installation and has better signal. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0025] Typical embodiments that embody the features and advantages of the present invention will be described in detail in the following description. It should be understood that the present invention can have various changes in different embodiments without departing from the scope of the present invention, and the descriptions and illustrations therein are essentially used for illustration purposes rather than for limiting the present invention.

[0026] In the description of the present application, the terms "first", "second", etc. are only used to facilitate the description of the present application and simplify the description, and do not indicate or imply that the structure referred to must have a specific orientation, be constructed and operate in a specific orientation, and therefore should not be understood as a limitation on the present application.

[0027] See also Figures 1 to 4 As shown, the external Bluetooth module disclosed in this embodiment is applied to lamp control, and includes a Bluetooth module consisting of a PCB board 1, a Bluetooth chip 2, and an antenna 3. The Bluetooth module is located outside the lamp cover, and the power module is located inside the lamp cover. The Bluetooth module is separated from the power module, and the PCB board 1 is installed in a shell 4. The Bluetooth chip 2 and the antenna 3 are integrated on the PCB board 1, and the PCB board 1 is connected to the power module through a connecting line; the antenna 3 and the Bluetooth chip 2 are separated from the power module, and the external Bluetooth module can be selectively installed according to user needs; after the separation, the antenna 3 of the external Bluetooth module is in the shell, which is not easily affected by the external environment, and because the external Bluetooth module can adjust the installation direction by itself, the stable transmission of the signal is guaranteed.

[0028] In this embodiment, the Bluetooth chip 2 adopts the NRF52833 chip, the antenna 3 adopts the ceramic antenna 3, the Bluetooth module is provided with an interface (VCC GND TX RX), and the power module is provided with a communication interface, which is connected to the Bluetooth chip 2 through TX and RX pins; through the above improvements, the signal transmission distance is increased from the conventional 10M to 100M, the wiring is simple, there is no clearance area and shape requirements, and the external Bluetooth module has an MCU because the Bluetooth chip itself adopts an MCU, and the power supply also has an MCU, so that the external Bluetooth module can be programmed to apply different firmware and is not limited to one control platform; due to the use of a ceramic antenna and an external method, compared with the original U-shaped wiring method integrated on the power PCB board, this wiring method is simpler.

[0029] Among them, see Figure 3 and Figure 4 As shown, the shell 4 includes an upper shell 41 and a lower shell 42, the upper shell 41 is snap-fitted with the lower shell 42, the outer wall of the upper shell 41 is close to the inner wall of the lower shell 42, the PCB board 1 is installed on the inner top surface of the upper shell 41, one end surface of the antenna 3 is close to the PCB board 1, and the other end surface is close to the inner bottom surface of the lower shell 42, and the three side walls of the ceramic antenna are close to the corresponding inner walls of the upper shell 41; the upper shell 41 and the lower shell 42 are tightly buckled, and the side walls of the two are against each other, and the whole is more stable. Since the ceramic antenna mainly includes a ceramic substrate, the ceramic substrate is square, before assembly, the ceramic substrate is located at the bottom of the upper shell 41, and after assembly, the upper shell 41 can limit the three side walls of the ceramic substrate. When the external Bluetooth module is impacted, the force is more uniform, so that the welding point on the bottom surface of the ceramic substrate is not easy to separate from the PCB board 1.

[0030] See also Figure 1 As shown, a threaded sleeve 43 is vertically provided on the upper part of the upper shell 41, and a nut 44 is screwed on the threaded sleeve 43. A through hole is opened in the threaded sleeve 43 of the upper shell 41, and the connecting port 411 of the PCB board 1 is arranged in the through hole; the above structure can realize two installation methods. First, when there is a through groove or through hole larger than the outer diameter of the threaded sleeve 43 on the frame of the lamp, the upper shell 41 can be pushed in from bottom to top, and the threaded sleeve 43 passes through the through groove or through hole, and then the threaded sleeve 43 passing through the through groove or through hole is locked by the nut 44; second, when there is a threaded hole matching the threaded sleeve 43 on the frame, it can be directly screwed into the threaded hole; the threaded sleeve 43 not only plays the role of installation, but the connecting port is located in the threaded sleeve 43, and the threaded sleeve 43 can play a certain waterproof and dustproof role on the wiring part.

[0031] See also Figure 3 and Figure 4As shown, the outer wall of the upper shell 41 is vertically provided with a card slot 412, and the upper shell 41 is provided with a first positioning slot 413 below the card slot 412. The outer wall of the lower shell 42 is provided with an elastic card block 421. When assembling, the elastic card block 421 can slide along the first positioning slot 413 and then engage with the card slot 412; second positioning slots 414 are provided on both sides of the upper shell 41, and a positioning plate 422 is horizontally provided in the lower shell 42. The positioning plate 422 is engaged with the second positioning slot 414 and is close to the side wall of the ceramic antenna. The Bluetooth chip 2 is located on the other side of the positioning plate 422; when only the card slot 412 is provided for assembly, the upper shell 41 is assembled. During the insertion process of the lower shell 42, the elastic block 421 first contacts and squeezes the outer wall of the upper shell 41. At this time, it is more laborious to continue to press the lower shell 42. Therefore, by setting the first positioning groove 413, it not only plays a positioning role before assembly, but also the elastic block 421 can slide along the first positioning groove 413 effortlessly during assembly, shortening the squeeze stroke of the elastic block 421 during assembly, and the insertion process is easier; by setting the second positioning groove 414 to engage with the positioning plate 422, the stability of the overall structure is increased, and one side of the positioning plate 422 limits one side of the ceramic antenna, and cooperates with the upper shell 41 to limit the four sides of the ceramic antenna 3, making the whole structure more stable.
