Technical Field

[0002] There are many styling styles and functions for existing model cars and toy cars. Model cars are scaled-down versions of real cars according to a certain ratio. For some special types of model cars, such as model police cars, model ambulances, or model fire trucks, in order to make them look more realistic, an alarm light device needs to be designed.

[0003] Existing rotating lamp bodies are usually more suitable for the simultaneous rotation of multiple lamp bodies. Due to the limitation of multiple lamp bodies, the structure driving their rotation is relatively complex, and the overall occupied volume and space of the rotating device are relatively large, making it impossible to miniaturize the overall structure. How to provide a micro rotating device suitable for a single lamp body has become an urgent problem to be solved. Summary of the Utility Model

[0004] Aiming at the problem that the existing rotating structure of multiple lamp bodies is relatively complex for a single lamp body and cannot miniaturize the overall structure, the utility model provides a micro mechanical rotating device for models.

The bottom of the first housing is snap-connected to the first base, the top of the first housing is snap-connected to the second housing and is transparent. The mounting seat is installed on the upper part of the rotating structure. The rotating structure includes a second base and a motor. The rotating structure is connected to the second base through the bearing. One end of the bearing away from the second base is connected to the mounting seat. The motor is used to drive the second base to rotate. The motor is installed in the first housing, and the bottom of the motor abuts against the inner bottom wall of the first base;

[0007] A semi-circular arc-shaped cover is provided on the mounting seat. A lamp body is arranged inside the semi-circular arc-shaped cover. A rigid connecting wire is fixedly connected to the lamp body. The connecting wire is fixedly installed on the first housing and is externally connected to a circuit board or a power source.

[0008] Through the above technical solution, a motor is installed inside the first housing. By providing a second base, the motor directly drives the second base to rotate, and the mounting seat is installed on the top of the first base. In this way, the motor can drive the mounting seat to rotate, and then drive the semi-circular cover to rotate. The light passes through the semi-transparent second housing to achieve intermittent flashing of the lamp body. While realizing the function of the warning lamp, for a single lamp body, the structure is compact, so that the overall volume can be made relatively small.

[0009] Preferably, a cavity for accommodating the motor is provided near the inner wall of the first housing, the motor is vertically installed in the cavity, a first gear is installed on the inner wall of the second base, and a gear assembly meshing with the first gear is installed on the output end of the motor.

[0010] Through the above technical solution, the motor is fixed around by the cavity, and the second base is driven to rotate by the meshing of the first gear and the gear assembly. The efficiency is high, and the first gear is provided on the inner wall of the second base, which saves more space.

[0013] Through the above technical solution, when the motor starts, the driving gear drives the first driven gear to rotate, and then drives the third driven gear to rotate through the second driven gear, so as to drive the second base to rotate through the first gear, thereby realizing the motor driving the semi-circular cover to rotate, and the structure is compact.

[0014] Preferably, a partition and a fixing seat are provided in the first housing. The partition is located on the side of the mounting seat close to the semi-circular cover. The gear assembly is arranged above the partition.

The irregular limiting block surrounds the rotating shaft of the motor. The driving gear and the first driven gear are located above the irregular limiting block and are arranged adjacent to the irregular limiting block.

[0021] Through the above solution, the setting of the irregular limiting block can, on the one hand, limit the installation of the motor and improve the stability of the motor during installation and operation; on the other hand, it can play a role in supporting and limiting the installation of the driving gear and the first driven gear.

[0022] Preferably, the second base is provided with a step, and the mounting seat is clamped to the top of the step through a mounting pad.

Referring to Figures 1-4 、 Figure 10 and Figure 11 , the micro mechanical rotating device for a model includes a first base 1, a first housing 2, a rotating structure, a mounting base 4, a bearing 61 and a second housing 5. The bottom of the first housing 2 is connected to the first base 1 by a snap connection, and the lower part of the second housing 5 is also connected to the first housing 2 by a snap connection.

[0043] The inside of the first base 1 is hollow. The diameter of the outer wall at the bottom of the first housing 2 is slightly smaller than the inner diameter of the first base 1, so that snap connection can be realized. The outer diameter of the middle part of the first housing 2 is the same as the outer diameter of the first base 1, which looks more beautiful. A relief hole 15 is provided in the middle of the first base 1, and a through pipe is connected at the relief hole 15.

[0044] The rotating structure includes a second base 6 and a motor 7. The motor 7 is used to drive the second base 6 to rotate, and the motor 7 is installed in the first housing 2. The rotating structure is connected to the second base 6 through a bearing 61. One end of the bearing 61 away from the second base 6 is connected to the mounting seat 4. The outer diameters of the upper and lower parts of the first housing 2 are slightly smaller than the outer diameter of the middle part. A hollow cavity 8 is designed to closely adhere to the inner wall of the first housing 2. The motor 7 is located in the cavity 8, and the circumferential side of the motor 7 is fixed through the cavity 8. The lower part of the cavity 8 exceeds the first housing 2, and the bottom surface of the motor 7 abuts against the bottom wall in the first base 1 to fix the bottom of the motor 7. A step 13 is provided on the second base 6, and the mounting seat 4 is snap-connected to the top of the step 13 through a mounting pad 41, which facilitates the connection between the mounting seat 4 and the second base 6.

[0045] Referring to Figures 1-5 , a semi-circular cover 3 is provided on the mounting seat 4. A lamp body 11 is arranged inside the semi-circular cover 3. The lamp body 11 uses an LED lamp. A rigid connecting wire 111 is fixedly connected to the lamp body 11. The connecting wire 111 is fixedly installed on the first housing 2 and is externally connected to a circuit board or a power source. In this application, the motor 7 is installed in the first housing 2. By setting the second base 6, the motor 7 directly drives the second base 6 to rotate, and the mounting seat 4 is installed on the top of the first base 1. In this way, the motor 7 can drive the mounting seat 4 to rotate, and then drive the semi-circular cover 3 to rotate. The light passes through the semi-transparent second housing 5 to realize the intermittent flashing of the lamp body 11. While realizing the function of the warning lamp, for a single lamp body 11, the structure is compact, so that the overall volume can be made relatively small.

[0046] Referring to Figures 4-7 , a first gear 9 is installed on the inner wall of the second base 6. A gear assembly meshing with the first gear 9 is installed on the output end of the motor 7. The second base 6 is driven to rotate by the meshing of the first gear 9 and the gear assembly. The efficiency is high, and the first gear 9 is arranged on the inner wall of the second base 6, which saves more space. The gear assembly includes a driving gear 10, a first driven gear 101, a second driven gear 102 and a third driven gear 103 rotatably arranged in the first housing 2. The second driven gear 102 and the third driven gear 103 are integrally connected.

[0047] The driving gear 10 is coaxially arranged on the output shaft of the motor 7. The first driven gear 101 meshes with the driving gear 10. The second driven gear 102 is coaxially arranged with the first driven gear 101 and is located on the side of the first driven gear 101 close to the first base 1. The diameter of the second driven gear 102 is smaller than that of the first driven gear 101. One side of the third driven gear 103 meshes with the second driven gear 102, and the other side of the third driven gear 103 meshes with the driving gear 10. When the motor 7 is started, the driving gear 10 drives the first driven gear 101 to rotate, and then drives the third driven gear 103 to rotate through the second driven gear 102. This realizes the rotation of the second base 6 through the first gear 9, and thus the rotation of the semicircular arc cover 3 by the motor 7, resulting in a compact structure.

[0048] Reference Figures 4-9 A partition 21 and a fixing seat 22 are fixedly installed within the first housing 2. The partition 21 is located on the side of the mounting seat 4 near the semicircular cover 3. The gear assembly is arranged above the partition 21. A first gear limiting tube 23, a second gear limiting tube 24, a first thread limiting tube 25, and a second thread limiting tube 26 are fixedly installed on the fixing seat 22 and pass through the partition 21. The first driven gear 101 and the second driven gear 102 are inserted and restrained in the first gear limiting tube 23 via the first rotating shaft. The third driven gear 103 is inserted and restrained in the second gear limiting tube 24 via the second rotating shaft.

[0049] The first and second wire limiting tubes 25 and 26 extend through the fixing base 22. The lamp body 11 has two connecting wires 111. A clearance space is provided between the gear assembly and the inner wall of the first housing 2. The two connecting wires 111 pass through the clearance space and then through the first and second wire limiting tubes 25 and 26, respectively. This facilitates the rotational installation of the gear assembly and the installation of the lamp body 11, resulting in a simple structure and easy installation. The connecting wires 111 of the lamp body 11 then pass through the first and second wire limiting tubes 25 and 26, then through the clearance hole 15 via a connected soft wire to achieve external connection to a circuit board or power supply.

[0050] Reference Figure 8 The fixing seat 22 includes four connecting columns 221 and three connecting plates 12. The outer wall of the cavity 8 is connected to the inner wall of the first shell 2 through the connecting columns 221 and the connecting plates 12. The first gear limiting tube 23, the second gear limiting tube 24, the first wire limiting tube 25 and the second wire limiting tube 26 are correspondingly arranged in the connecting columns 221. The cavity 8 is arranged close to the inner wall of the first shell 2, which is equivalent to the motor 7 not being installed in the center. It helps to install the gear assembly while leaving space for the connecting wire 111 to pass through, further saving installation space. And through the setting of the fixing seat 22, the connecting wire 111 of the gear assembly and the lamp body 11 has an installation foundation, saving materials and enhancing the structural strength inside the first shell 2.

[0051] Refer to Figure 4 and Figure 9 Figure 9 , the top of the body of the motor 7 abuts against the bottom surface of the partition plate 21. An irregular limiting block 211 is fixedly installed on the partition plate 21. The irregular limiting block 211 surrounds the rotating shaft of the motor 7. The driving gear 10 and the first driven gear 101 are located above the irregular limiting block 211 and are arranged adjacent to the irregular limiting block 211. The setting of the irregular limiting block 211 can, on the one hand, limit the installation of the motor 7 and improve the stability of the motor 7 during installation and operation; on the other hand, it can play a role in supporting and limiting the installation of the driving gear 10 and the first driven gear 101.
