Description

Technical Field

[0001] This utility model relates to the field of electronic communication technology, and in particular to a Bluetooth voice receiver. Background Technology

[0002] Bluetooth voice refers to the application method of voice transmission using Bluetooth technology. It is an application method that converts voice signals into electrical signals and then into data signals to operate and control devices. To facilitate the reception of Bluetooth signals, a Bluetooth voice receiver is required.

[0003] A search revealed Chinese Patent Publication No. CN222053301U, which discloses a wireless microphone repeater device. The device includes a main body with a PCB board inside, on which a Bluetooth module is mounted. The main body has a camera connection port and a receiver connection port, both electrically connected to the PCB board. This invention aims to provide a cost-effective wireless microphone repeater device. However, in practical use, the sealed design of the casing makes it difficult to dissipate internal heat over long periods. The accumulation of heat reduces sound quality stability, increases power consumption, and affects the lifespan of the internal battery, thus reducing the device's reliability. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a Bluetooth voice receiver, which aims to improve the problem of insufficient heat dissipation of internal heat accumulation in existing voice receivers.

[0005] To achieve the above objectives, this utility model adopts the following technical solution: a Bluetooth voice receiver, including a housing, a receiver fixedly connected to the bottom of the inner wall of the housing, rotating rods rotatably connected to all four sides of the inner wall of the housing, a third rotating wheel fixedly connected to the front side of the upper rotating rod, a cleaning cover provided on the outer side of the rotating rod, and multiple rotating rods being connected to each other through the cleaning cover; second rotating wheels rotatably connected to the left and right sides of the front end of the inner wall of the housing; a motor fixedly connected to the middle of the front end of the inner wall of the housing, and a first rotating wheel fixedly connected to the output end of the motor; the outer side of the first rotating wheel... A belt is provided, and the first rotating wheel is connected to the second rotating wheel via the belt. The second rotating wheel is connected to the third rotating wheel via the belt. A first bevel gear rod is fixedly connected to the rear side of the second rotating wheel. Fan blades are rotatably connected to the top left and right sides of the inner wall of the outer casing. A second bevel gear rod is fixedly connected to the bottom of the fan blades. The second bevel gear rod is connected to the first bevel gear rod. Heat dissipation plates are fixedly connected to the left and right sides of the outer wall of the outer casing. A positioning mechanism is provided on the front side of the outer casing. The positioning mechanism is used to fix the device and position the equipment inserted into the device.

[0006] Through the above technical solution: after the motor is started, the first rotating wheel rotates accordingly, and the belt transmits power, driving the second and third rotating wheels to rotate synchronously. When the third rotating wheel rotates, it drives the cleaning hood to remove impurities from the heat dissipation plate. At the same time, the second rotating wheel drives the second bevel gear rod, and the meshing transmission causes the fan blades to rotate, which accelerates airflow for heat dissipation and also prevents impurities from adhering, thus extending the service life of the equipment.

[0007] As a further description of the above technical solution:

[0008] The positioning mechanism includes mounting plates, two of which are slidably connected to the upper and lower front sides of the outer wall of the housing. A bidirectional threaded rod is rotatably connected to the inner side of the mounting plate. Hollow telescopic plates are threadedly connected to the left and right sides of the outer wall of the bidirectional threaded rod. A gear is rotatably connected to the middle of the inner side of the hollow telescopic plate. A rack is slidably connected to the front and rear sides of the inner wall of the hollow telescopic plate. The outer sides of multiple racks are respectively connected to the upper and lower bottom sides of the inner wall of the hollow telescopic plate. A clamping plate is fixedly connected to the front side of the hollow telescopic plate.

[0009] The above technical solution allows the gear to rotate and drive the rack to move up and down through meshing transmission. The movement of the rack can drive the telescopic plate to operate synchronously, thereby precisely controlling the position of the mounting plate and firmly fixing the structure of the insertion device. At the same time, rotating the bidirectional threaded rod uses the threaded connection to drive the telescopic plate to move left and right, fixing both sides of the structure. When no connection is needed, it also fixes the device itself.

[0010] As a further description of the above technical solution:

[0011] Positioning blocks are fixedly connected to the bottom of the outer wall of the outer shell around all four sides, and positioning holes are opened on the outer side of the positioning blocks.

[0012] The above technical solution facilitates the installation and fixation of the device by installing threaded parts in the positioning holes.

[0013] As a further description of the above technical solution:

[0014] The outer wall of the outer shell is fixedly connected to handles around the center, and the outer side of each handle is fixedly connected to a protective sleeve.

[0015] The above technical solution improves the comfort of holding the device by using a handle and a protective cover.

[0016] As a further description of the above technical solution:

[0017] A controller is fixedly connected to the top center of the housing, and the controller is electrically connected to the motor.

[0018] The above technical solution enables the controller to control the starting and operation of the motor.

[0019] As a further description of the above technical solution:

[0020] A movable door is provided on the rear side of the outer casing. Hinges are fixedly connected to the left and right sides of the outer wall of the movable door. The movable door is connected to the outer casing through the hinges.

[0021] The above technical solution allows for easy maintenance of the device's internal components by using hinges to open and close the movable door.

[0022] As a further description of the above technical solution:

[0023] A knob is rotatably connected to the right side of the outer wall of the mounting plate, and the outer side of the knob passes through the mounting plate and is fixedly connected to the bidirectional threaded rod.

[0024] The above technical solution allows the bidirectional threaded rod to be manually rotated via a knob.

[0025] As a further description of the above technical solution:

[0026] A handle is rotatably connected to the outer side of the hollow telescopic plate, and the outer side of the handle passes through the hollow telescopic plate and is fixedly connected to the gear.

[0027] The above technical solution allows the gears to rotate easily by holding the handle.

[0028] This utility model has the following beneficial effects:

[0029] 1. In this utility model, the first rotating wheel is driven to rotate by the starting motor, and the second and third rotating wheels are driven to rotate by the belt transmission. When the third rotating wheel rotates, it will drive the cleaning cover to clean the impurities on the heat sink plate. At the same time, the rotation of the second rotating wheel will drive the second bevel gear rod to rotate. It can rotate with the fan blade through meshing transmission, which can promote airflow and improve the heat dissipation effect. At the same time, it can prevent impurities from adhering to the surface of the heat sink, improve the service life, and thus reduce the reliability of the device.

[0030] 2. In this utility model, the rotating gear drives the rack to move up and down through meshing transmission. The rack drives the telescopic plate, thereby controlling the position of the mounting plate to fix the structure of the insertion device. At the same time, rotating the bidirectional threaded rod allows the telescopic plate to move left and right to fix both sides of the structure through threaded connection. This facilitates the connection of the device to external equipment and can fix itself when not connected, thereby improving the convenience of the device. Attached Figure Description

[0038] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0039] Reference Figure 1 , Figure 3 and Figure 4This utility model provides an embodiment of a Bluetooth voice receiver, including a housing 1. A receiver 13 is fixedly connected to the bottom of the inner wall of the housing 1. Rotating rods 6 are rotatably connected to all four sides of the inner wall of the housing 1. A third rotating wheel 8 is fixedly connected to the front side of the upper rotating rod 6. A cleaning cover 7 is provided on the outer side of the rotating rod 6. The multiple rotating rods 6 are connected to each other through the cleaning cover 7. Second rotating wheels 5 are rotatably connected to the left and right sides of the front end of the inner wall of the housing 1. A motor 3 is fixedly connected to the middle of the front end of the inner wall of the housing 1. A first rotating wheel 4 is fixedly connected to the output end of the motor 3. A belt 22 is provided on the outer side of the first rotating wheel 4. The first rotating wheel 4 is connected to the second rotating wheel 5 via belt 22. The second rotating wheel 5 is connected to the third rotating wheel 8 via belt 22. The rear side of the second rotating wheel 5 is fixedly connected to the first bevel gear rod 10. The top left and right sides of the inner wall of the outer casing 1 are rotatably connected to fan blades 12. The bottom of the fan blades 12 is fixedly connected to the second bevel gear rod 11. The second bevel gear rod 11 is connected to the first bevel gear rod 10. The left and right sides of the outer wall of the outer casing 1 are fixedly connected to heat dissipation plates 9. The front side of the outer casing 1 is provided with a positioning mechanism 2. The positioning mechanism 2 is used to fix the device and position the equipment inserted into the device.

[0040] Specifically, the starter motor 3 drives the first rotating wheel 4 to rotate, which in turn drives the second rotating wheel 5 and the third rotating wheel 8 to rotate via the belt 22. The third rotating wheel 8 drives the rotating rod 6 to make the cleaning cover 7 rotate around the axis, adsorbing and cleaning the impurities attached to the surface of the heat sink 9. At the same time, the rotation of the second rotating wheel 5 synchronously drives the second bevel gear rod 11 to rotate, thereby making it and the connected fan blade 12 rotate through meshing transmission, accelerating the airflow and causing the heat inside the device to dissipate quickly with the airflow, while also preventing impurities from accumulating on the surface of the heat sink 9.

[0041] Reference Figure 1 , Figure 2 and Figure 5 The positioning mechanism 2 includes a mounting plate 201. Two mounting plates 201 are slidably connected to the upper and lower sides of the front end of the outer wall of the outer shell 1. A bidirectional threaded rod 202 is rotatably connected to the inner side of the mounting plate 201. Hollow telescopic plates 203 are threadedly connected to the left and right sides of the outer wall of the bidirectional threaded rod 202. A gear 204 is rotatably connected to the middle of the inner side of the hollow telescopic plate 203. A rack 205 is slidably connected to the front and rear sides of the inner wall of the hollow telescopic plate 203. The outer sides of the multiple racks 205 are respectively connected to the upper and lower sides of the bottom of the inner wall of the hollow telescopic plate 203. A clamping plate 206 is fixedly connected to the front side of the hollow telescopic plate 203.

[0042] Specifically, rotating the gear 204 simultaneously causes the rack 205 to move up and down via meshing transmission, thereby controlling the vertical displacement of the hollow telescopic plate 203 and adjusting the position of the mounting plate 201 to fix the vertical position of the structure inside the insertion device. At the same time, rotating the bidirectional threaded rod 202 uses the threaded connection characteristics to drive the hollow telescopic plate 203 to move left and right, firmly fixing the left and right sides of the insertion structure. Through this dual fixing method, the device can be tightly fixed when connected to external equipment, and can quickly fix itself when not connected.

[0043] Reference Figure 1 , Figure 2 and Figure 3 The outer wall of the outer shell 1 is fixedly connected to the bottom four sides of the outer shell 1, and the outer side of the positioning block 19 is provided with positioning hole 20; the outer wall of the outer shell 1 is fixedly connected to the middle four sides of the outer shell 1, and the outer side of the handle 17 is fixedly connected to the protective sleeve 18; the top center of the outer shell 1 is fixedly connected to the controller 14, and the controller 14 is electrically connected to the motor 3.

[0044] Specifically, by installing threaded parts in the positioning holes 20 on the positioning block 19, the device can be easily installed and fixed. The handle 17 makes it easy to hold and carry the device, and the protective sleeve 18 on it can improve the comfort of holding the device. The controller 14 can control the starting and running power of the motor 3.

[0045] Reference Figure 1 , Figure 3 and Figure 5 A movable door 21 is provided on the rear side of the outer casing 1. Hinges 23 are fixedly connected to the left and right sides of the outer wall of the movable door 21. The movable door 21 is connected to the outer casing 1 through the hinges 23. A knob 15 is rotatably connected to the right side of the outer wall of the mounting plate 201. The outer side of the knob 15 passes through the mounting plate 201 and is fixedly connected to the bidirectional threaded rod 202. A handle 16 is rotatably connected to the outer side of the hollow telescopic plate 203. The outer side of the handle 16 passes through the hollow telescopic plate 203 and is fixedly connected to the gear 204.

[0046] Specifically, the hinge 23 can open and close the movable door 21 to facilitate maintenance of the device's interior, the operating knob 15 can be used to manually drive the bidirectional threaded rod 202 to rotate, and the operating handle 16 can be used to drive the gear 204 to rotate.

[0047] Working principle: Before using the device, the motor 3 is started to drive the first rotating wheel 4 to rotate. At this time, the second rotating wheel 5 and the third rotating wheel 8 are driven to rotate through the belt 22. As the third rotating wheel 8 rotates, the rotating rod 6 drives the cleaning cover 7 to rotate. The rotation of the cleaning cover 7 can remove impurities attached to the surface of the heat sink 9. At the same time, the rotation of the second rotating wheel 5 drives the second bevel gear rod 11 to rotate. Through meshing transmission, the second bevel gear rod 11 and the fan blade 12 on it rotate to promote airflow and improve the airflow and heat dissipation effect. It can prevent impurities from adhering to the surface of the heat sink 9 while dissipating heat from the device.

[0048] Furthermore, the transmission gear 204 can drive the rack 205 to move up and down through meshing transmission. At this time, as the rack 205 moves, the hollow telescopic plate 203 can be adjusted to move up and down, thereby controlling the up and down position of the mounting plate 201 and fixing the structure inside the insertion device. At the same time, rotating the bidirectional threaded rod 202 can drive the hollow telescopic plate 203 to move left and right through the threaded connection, thereby fixing the left and right sides of the structure inside the insertion device. This allows the device to be fixed to the external equipment when connected to it, and to be fixed to the desired installation position when not fixed to the external equipment.

[0049] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
