[0047] The following is a clear and complete description of the technical solution of the present invention in conjunction with the accompanying drawings. Obviously, the embodiments described are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative efforts are within the scope of protection of the present invention.

[0048] In the description of the present invention, it should be noted that, unless otherwise expressly specified or limited, the terms "installed," "connected," and "connected" should be understood in a broad sense. For example, they may refer to fixed connections, detachable connections, or integral connections; they may refer to mechanical connections or electrical connections; they may refer to direct connections or indirect connections through an intermediate medium; they may refer to internal connections between two components; they may refer to wireless connections or wired connections. Those skilled in the art will understand the specific meanings of the above terms in the present invention based on the specific circumstances.

[0049] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of the technical features being referred to. Thus, a feature specified as "first" or "second" may explicitly or implicitly include at least one such feature. In the description of this utility model, "plurality" means at least two, such as two, three, etc., unless otherwise specifically defined.

[0050] In the present invention, unless otherwise expressly specified or limited, when a first feature is "above" or "below" a second feature, it may mean that the first and second features are in direct contact, or the first and second features are in indirect contact through an intermediary. Furthermore, when a first feature is "above," "above," or "above" a second feature, it may mean that the first feature is directly above or diagonally above the second feature, or simply means that the first feature is at a higher level than the second feature. When a first feature is "below," "below," or "below" a second feature, it may mean that the first feature is directly below or diagonally below the second feature, or simply means that the first feature is at a lower level than the second feature.

[0051] See also Figure 1-6 As shown, the embodiment of the present invention provides a small antenna retracting device, which includes a housing 1, a worm gear assembly 2, a gear set transmission assembly 3, a motor assembly 4 and a retracting frame 5, wherein:

[0052] The housing 1 serves as a supporting structure for the entire device. As a preferred embodiment of this embodiment, the housing 1 has two horizontally separated first accommodating chambers 16 and second accommodating chambers 17 to isolate different components, reduce interference, and provide physical protection.

[0053] The worm gear assembly 2 is a key part for achieving precise motion control, and is usually used to convert rotational motion into linear motion, etc. The worm gear assembly 2 in this embodiment includes a worm 21, an arc-shaped worm wheel 22 and a rotating shaft 23. The worm 21 is horizontally rotated and arranged at the bottom of the first accommodating chamber 16. The arc-shaped worm wheel 22 is located directly above the worm 21 and engages with the worm 21 for transmission. The rotating shaft 23 horizontally passes through the first accommodating chamber 16, and the arc-shaped worm wheel 22 is passed through the rotating shaft 23 and is located at the top of the first accommodating chamber 16.

[0054] The worm gear assembly 2 is used to transmit motion and power between the staggered axes, with the two axes staggered at an angle of 90 degrees. In this device, the worm 21 is engaged with the arc-shaped worm wheel 22 as the active element to achieve the transmission of motion.

[0055] In addition, worm gear transmission can achieve a larger transmission ratio. Because the worm has fewer teeth, while the worm wheel can have a large number of teeth, the transmission ratio can be very large, generally 10-100; finally, worm gear transmission generally has self-locking properties, which allows the device to remain in position when needed.

[0056] In order to increase the speed and adjust the torque, the gear set transmission assembly 3 is installed in the second accommodating chamber 17, and the gear set transmission assembly 3 is connected to the side of the worm 21 extending into the second accommodating chamber 17. In this way, the combination of the worm gear assembly 2 and the gear set transmission assembly 3 provides an efficient motion transmission method, ensuring the accuracy and reliability of the antenna's retraction.

[0057] The motor assembly 4 is the power source responsible for driving the rotation of the worm 21. In this embodiment, the motor assembly 4 is mounted within the second accommodating chamber 17, and the output shaft of the motor assembly 4 is connected to the end of the worm 21. This allows the motor assembly 4 to rotate the worm 21, transmitting the rotational motion to the curved worm gear 22 via the worm gear assembly 2. The inverted frame 5 is directly connected to the antenna and is responsible for supporting and moving the antenna. In this embodiment, the inverted frame 5 is fixedly mounted on both sides of the rotating shaft 23 to securely support the antenna. The inverted frame 5 moves with the rotation of the rotating shaft 23, thereby achieving the inverted and erected position of the antenna.

[0058] For further information, see Figure 5 As shown, the sector angle of the arc-shaped worm gear 22 is 165 degrees, which can greatly reduce the weight and the volume of the housing 1, and is conducive to further compressing the space and weight of the lodging device.

[0059] Compared to full disc-shaped worm gears, curved worm gears, due to their fan-shaped design, offer advantages such as compactness. They are often used in precision instruments to enhance the compactness of the overall transmission structure, reduce overall structural volume, and contribute to weight reduction, especially in applications where weight reduction is required to improve performance. For example, in lightweighting research on lodging devices, significant weight reduction and reduced housing volume were achieved through design optimization.

[0060] For further information, see Figure 5 As shown, the gear set transmission assembly 3 includes a first gear 31, an intermediate gear 32 and a second gear 33, wherein the second gear 33 is installed on the side of the worm 21 close to the motor assembly 4, and the transmission ratio between the first gear 31, the intermediate gear 32 and the second gear 33 is 1:1:2.

[0061] Specifically in this embodiment, when the motor assembly 4 fails or the antenna retraction work needs to be manually started, the power input is provided by the gear group transmission assembly 3, and the rotational motion of the first gear 31 is transmitted to the intermediate gear 32, and the intermediate gear 32 is transmitted to the second gear 33. The second gear 33 is installed on the worm 21, thereby driving the worm 21 to engage with the arc-shaped worm gear 22. The swing of the arc-shaped worm gear 22 at a certain angle will drive the retraction frame 5 to swing within a certain angle range through the rotating shaft 23.

[0062] The transmission ratio between the first gear 31, the intermediate gear 32 and the second gear 33 is 1:1:2. When the first gear 31 rotates one circle, the intermediate gear 32 also rotates one circle, and the second gear 33 rotates 2 circles, so that the speed and torque are transmitted between the gears in a specific ratio.

[0063] Thus, the gear set transmission assembly 3 achieves a significant increase in speed and adjustment of torque through a transmission ratio of 1:1:2, which is very beneficial for applications requiring high speed and fine torque control.

[0064] For further information, see Figure 5 As shown, the gear set transmission assembly 31 also includes a hand-cranked shaft component 34 installed on the top of the second accommodating chamber 17. The hand-cranked shaft component 34 includes a hand-cranked shaft seat 341 fixed on the inner wall of the second accommodating chamber 17 and a hand-cranked shaft 342 horizontally passed through the hand-cranked shaft seat 341. The end of the hand-cranked shaft 342 close to the first gear 31 is passed through and connected to the first gear 31.

[0065] When motor assembly 4 fails or requires manual operation, manual crankshaft component 34 manually rotates crankshaft 342 to drive first gear 31. First gear 31 transmits torque to worm 21 and curved worm gear 22 via intermediate gear 32 and second gear 33, thereby achieving the antenna's tilting motion. This design provides both automatic and manual operation modes, increasing system redundancy and flexibility.

[0066] For further information, see Figure 1 、 3 As shown in Figure 5, the shell 1 includes an upper shell 11, a lower shell 12 connected to one side of the bottom of the upper shell 11, a side cover 13 connected between the upper shell 11 and the lower shell 12, and a rotating shaft cover 14 sealed and connected to the position where the rotating shaft 23 passes through the upper shell 11. A first accommodating chamber 16 is formed on the side of the upper shell 11 away from the lower shell 12, and a second accommodating chamber 17 is formed together between the upper shell 11, the lower shell 12 and the side cover 13.

[0067] In this embodiment, the housing 1 comprises an upper housing 11, a lower housing 12, a side cover 13, and a rotating shaft cover 14. This modular design facilitates manufacturing, assembly, and maintenance. The upper and lower housings 11 and 12 are connected, followed by the side cover 13 and finally the rotating shaft cover 14 to complete the assembly of the housing 1. The worm gear assembly 2 is mounted within the first accommodating chamber 16, while the gear train transmission assembly 3 and motor assembly 4 are mounted within the second accommodating chamber 17. This reduces interference between the various components and improves the overall performance and reliability of the device.

[0068] For further information, see Figure 5 As shown, the upper shell 11 is provided with a first bearing seat hole 111 and a second bearing seat hole 112 at both ends of the worm 21 respectively. The first bearing seat hole 111 is rotatably supported on the end of the worm 21 away from the motor assembly 4 through the first bearing, and the second bearing seat hole 112 is rotatably supported on the side of the worm 21 close to the motor assembly 4 through the second bearing, and the worm 21 extends into the second accommodating chamber 17 through the second bearing seat hole 112.

[0069] Specifically, the first bearing seat hole 111 and the second bearing seat hole 112 are used to install a first bearing and a second bearing, respectively. These bearings provide rotation support for the worm 21, reduce friction and wear, and ensure the smooth operation of the worm.

[0070] For further information, see Figure 5 As shown, there is a partition 15 between the first accommodating chamber 16 and the second accommodating chamber 17, whose main function is to isolate the first accommodating chamber 16 from the second accommodating chamber 17, ensure the independent operation of the worm gear assembly 2 and the gear set transmission assembly 3, reduce interference, and improve the overall stability of the device, and the intermediate gear 32 is installed on the partition 15 through the rotating shaft 321 to provide installation support for the rotation installation of the intermediate gear 32.

[0071] For further information, see Figure 1 、 2 As shown in Figures 3 and 4, the falling frame 5 includes a flange 51 and two support arms 52 vertically connected to both sides of the flange 51. The ends of the two support arms 52 facing away from the flange 51 are fixedly connected to the two ends of the rotating shaft 23 respectively.

[0072] Thus, the tilting frame 5 provides a stable structure for supporting and tilting the antenna through the design of the flange 51 and support arms 52. The flange 51 serves as the connection center, and the support arms 52 are vertically connected to it on both sides, forming a solid triangular support structure, enhancing the stability and load-bearing capacity of the entire tilting frame.

[0073] For further information, see Figure 3 、 4 , 6, the rotating shaft cover 14 includes:

[0074] The first rotating shaft cover sealing component 141 includes a first rotating shaft cover 1411, a first mechanical oil seal 1412, and a first lip seal ring 1413. The first rotating shaft cover 1411 is disposed on one side of the rotating shaft 23 and seals the first shaft hole 113 formed between the upper shell 11 and the rotating shaft 23. The first mechanical oil seal 1412 and the first lip seal ring 1413 are disposed on the rotating shaft 23 and are located within the first rotating shaft cover 1411.

[0075] The second rotating shaft cover sealing component 142 includes a second rotating shaft cover 1421, a second mechanical oil seal 1422 and a second lip-shaped sealing ring 1423. The second rotating shaft cover 1421 is passed through the other side of the rotating shaft 23 and is sealed on the second shaft hole 114 formed by the upper shell 11 and the rotating shaft 23. The second mechanical oil seal 1422 and the second lip-shaped sealing ring 1423 are passed through the rotating shaft 23 and are located in the second rotating shaft cover 1421.

[0076] Thus, the first rotating shaft cover sealing component 141 and the second rotating shaft cover sealing component 142 are respectively arranged on both sides of the rotating shaft 23. Each component includes a rotating shaft cover, a mechanical oil seal, and a lip seal. This design provides a double seal, ensuring the sealing performance between the rotating shaft and the housing.

[0077] For further information, see Figure 5 As shown, the hand crank shaft component 34 further includes a hand crank shaft cover 343 mounted on the outer wall of the side cover 13 , and the hand crank shaft cover 343 is connected to one end of the hand crank shaft 342 away from the first gear 31 .

[0078] Thus, the hand crank shaft component 34 converts the power of the human hand into mechanical energy through the hand crank shaft cover 343 to drive the internal mechanical structure to move. The operator can manually drive the hand crank shaft cover 343, and then realize the antenna's falling action through the gear train transmission assembly 31.

[0079] Although the utility model is disclosed as above, the scope of protection of the utility model is not limited thereto. Those skilled in the art may make various changes and modifications without departing from the spirit and scope of the disclosure, and these changes and modifications will fall within the scope of protection of the utility model.
