Description

Technical Field

[0001] This invention relates to the field of antenna technology, specifically to a multi-band adjustable device antenna. Background Technology

[0002] With the rapid development of wireless communication technology, smart devices such as portable routers, industrial handheld terminals, and drone communication modules are playing an increasingly important role in people's production and daily lives. The application scenarios for these devices are becoming increasingly diverse, ranging from relatively stable indoor or urban environments to areas with weak signals and strong interference, such as outdoor areas, basements, or remote locations. To meet the communication needs of different scenarios, various antenna enhancement solutions have emerged on the market, from simple built-in antenna optimization to complex external high-gain antennas, all aimed at improving the signal reception and transmission capabilities of these devices.

[0003] On the one hand, while fixed external antennas can provide significant signal gain, they are bulky, inconvenient to carry, and usually have limited functionality, making them unable to be flexibly adjusted according to the signal environment. On the other hand, detachable external antennas require manual plugging and unplugging by the user, which is cumbersome, prone to loss or damage, and often require device restart or reconfiguration during switching, affecting the continuity of use. In addition, although some multi-mode antennas integrate different forms, their switching and deployment actions usually rely on multiple independent operations or complex electronic control systems, which not only increases costs and failure rates but also fails to achieve intelligent linkage between mechanical actions and signal mode switching, resulting in a poor user experience. Therefore, a multi-band adjustable device antenna device is needed to solve the existing shortcomings. Summary of the Invention

[0004] Technical problems to be solved Existing antenna solutions struggle to balance portability and high performance, and generally suffer from cumbersome operation and unintelligent function switching. Technical solution

[0005] To achieve the above objectives, the present invention provides the following technical solution: a multi-band adjustable device antenna device, comprising: The antenna column has several receiving slots arranged along its circumferential array. Several support rods are rotatably connected to the corresponding receiving slots, and each support rod has a storage slot. Several antenna groups, each antenna group including a pair of antenna masts, which are rotatably connected to the corresponding storage slots; An unfolding assembly, disposed within the antenna column, is used to drive the support rod and antenna rod to switch between a retracted state and an unfolded state; A connector, movably mounted at the bottom of the antenna column, is used for electrical connection with external devices; and A switching component, located inside the antenna column and linked to the deployment component, switches the connection mode between the connector and the external device during the transition between the retracted and deployed states of the antenna column.

[0006] Furthermore, the connector includes a two-way plug, which has a first connection end and a second connection end; When the antenna mast is in the retracted state, the connecting end extends out of the antenna column and connects to an external device, and the device serves as a built-in antenna signal enhancer. When the antenna mast is in the deployed state, the second connecting end extends out of the antenna column and connects to external devices. The device uses the deployed antenna mast as an external antenna signal enhancer.

[0007] Furthermore, the switching component includes: A control element for controlling the radial movement of the bidirectional plug along the antenna post; A shielding element, movably mounted on the antenna column, is used to selectively shield or expose the movement path of the second connection terminal; and A linkage is connected between the control component and the blocking component, so that while the control component drives the bidirectional plug to move, it also drives the blocking component to release the obstruction of the second connection end.

[0008] Furthermore, the control element includes: A connecting rod is movably disposed inside the antenna column, and its bottom end is fixedly connected to the bidirectional plug. The control lever is rotatably connected to the antenna column and threadedly engaged with the connecting rod; and A knob, fixed to the end of the control lever, is used to drive the control lever to rotate, thereby causing the connecting rod and the bidirectional plug to move radially.

[0009] Furthermore, the linkage component includes: The rotating rod is rotatably connected to the antenna column and is threadedly engaged with the shielding component. Conical wheel one, fixed to the bottom end of the rotating rod; and Conical wheel two is fixed to the control rod of the control component and meshes with conical wheel one; The rotation of the control lever is transmitted to the rotary rod through the meshing of the first and second conical wheels, thereby driving the blocking component to move.

[0010] Furthermore, the unfolding component includes: A driving element, disposed within the antenna column, is used to control the expansion or retraction of the support rod relative to the antenna column; and The deployable component, disposed within the antenna column and linked to the drive component, is used to control the symmetrical deployment of a pair of antenna rods in each antenna group relative to the support rod when the support rod is deployed.

[0011] Furthermore, the driving element includes: The movable block is slidably connected inside the antenna column; Several connecting rods, each having one end hinged to the movable block and the other end hinged to a corresponding support rod; and The drive column is rotatably connected inside the antenna column, its bottom end is fixedly connected to the top end of the rotating rod, and is threadedly engaged with the moving block; The rotation of the drive column drives the moving block to move along the axial direction of the antenna column, which in turn drives the support rod to unfold or retract via the connecting rod.

[0012] Furthermore, the deployable component includes: A rotating shaft is used to rotatably connect each antenna mast to a corresponding storage slot; Gear 1, fixed on each of the said rotating shafts, and a pair of gears 1 on the same support rod mesh with each other to achieve symmetrical movement of the pair of antenna masts; and A synchronizing element is connected between the driving element and at least one of the rotating shafts, and is used to drive the corresponding rotating shaft to rotate when the driving element is activated.

[0013] Furthermore, the synchronization element includes: A rotating column is rotatably connected inside the antenna column; A traction rope has its first end fixed to one of the rotating shafts, and its second end wound around and fixed to the rotating column; The second traction rope has its first end fixed to the same rotating shaft, and its second end wound around and fixed to the rotating column, in the opposite direction to the winding of the first traction rope. A gear transmission mechanism is connected between the driving member and the rotating column, and is used to convert the linear motion of the driving member into the forward or reverse rotation of the rotating column; When the gear transmission mechanism drives the rotating column to rotate in the forward direction, the first traction rope is wound up while the second traction rope is released, thereby pulling the rotating shaft to rotate in the forward direction; when the rotating column rotates in the reverse direction, the second traction rope is wound up while the first traction rope is released, thereby pulling the rotating shaft to rotate in the reverse direction.

[0014] Furthermore, the gear transmission mechanism includes: Gear 2 is fixed to the rotating column; A guide cylinder, fixed to the top of the moving block of the driving component; and A rack is fixed to the outer periphery of the guide cylinder and meshes with the gear. The axial movement of the moving block is achieved by the meshing of the rack and gear two, which drives the rotating column to rotate.

[0015] Compared with existing technologies, this multi-band adjustable device antenna has the following advantages: I. This invention integrates the bidirectional plug with the switching and unfolding components, enabling simultaneous changes in antenna shape and switching of signal paths. Users only need a single rotation to switch from built-in to external enhancement modes, making the operation simple and ensuring seamless and instantaneous mode switching without requiring device restart or re-identification of hardware.

[0016] Second, by setting up a mechanical transmission chain with timing logic, this invention cleverly utilizes the travel difference of the moving blocks to achieve a two-stage deployment action of "first deploying the support rod, then deploying the antenna rod", effectively avoiding mechanical interference between components during the deployment process and ensuring the smoothness of the action and the reliability of the structure.

[0017] Third, by providing two switchable signal enhancement modes, built-in and external, this invention enables the device to adapt to different usage scenarios. In the stored state, it provides moderate signal gain with the advantage of portability, while in the unfolded state, it meets the communication needs of long-distance or weak signal environments with strong directionality and high gain, thus combining portability and high performance.

[0020] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0021] like Figure 1-8 As shown, the present invention provides a technical solution: a multi-band adjustable device antenna device. This device achieves simultaneous deployment of the antenna shape and switching of the signal path through a precise pure mechanical linkage system. It is especially suitable for smart devices that have dual requirements for signal strength and portability, such as portable routers, industrial handheld terminals, and drone communication modules.

[0022] Detailed explanation of signal enhancement mode and bidirectional plug 6: One of the core innovations of this invention is that it is not only a physical antenna, but also an intelligent signal mode switcher. This function is mainly achieved through the ingenious cooperation between the bidirectional plug 6 and the internal radio frequency circuit of the device. The bidirectional plug 6 is a specially designed multi-pin electrical connector that integrates two independent radio frequency signal paths as well as necessary grounding and control pins. It is movably located at the bottom of the antenna column 1, and its two connection ends (referred to as connection end one and connection end two for ease of description) can selectively mate with a single interface on the device according to the status of the device.

[0023] Mode 1: Built-in signal enhancement mode (storage state) like Figure 1 As shown, when the device is in the retracted state, all antenna masts 5 are retracted into the storage slot 4, and the support rod 3 is also retracted into the receiving slot 2. The entire device is compact and easy to carry. At this time, driven by the switching component 8, the connection end of the bidirectional plug 6 extends from the interface at the bottom of the antenna column 1 and is tightly connected to the RF interface of an external device (such as an industrial tablet computer).

[0024] In this mode, the signal path is: device RF module → connection terminal 1 → path A inside the bidirectional plug 6 → antenna post 1 itself or the PCB antenna / metal antenna integrated inside the antenna post 1.

[0025] The design goal of this approach is to provide better signal gain than the device's native antenna. Antenna post 1 is made of metal or a composite material containing an internal antenna radiator, and its size and shape are optimized to serve as an efficient "parasitic enhancer" for the device's built-in antenna or as a standalone, higher-performance built-in antenna. This is crucial for use in indoor or urban environments where the signal is slightly weaker but the environment is relatively stable, effectively improving communication stability and reducing dropped calls and stuttering without sacrificing portability.

[0026] Mode 2: External signal enhancement mode (deployed state) like Figure 3 As shown, when users need long-distance communication or operate in areas with extremely poor signal (such as the wild, basements, and remote mountainous areas), they can rotate knob 804 to fully extend the device. With mechanical linkage, the bidirectional plug 6 will move radially, retracting connector one and precisely extending connector two to mate with the same RF interface of the device.

[0027] In this mode, the signal path is switched as follows: device RF module → connection terminal 2 → path B inside bidirectional plug 6 → feed network inside antenna column 1 → fully deployed antenna column 5 array.

[0028] The deployed antenna mast 5 array forms a large antenna system with high gain and strong directivity (similar to a small Yagi antenna or a log-periodic antenna). Its physical dimensions and array spacing are optimized to cover multiple communication frequency bands, achieving enhanced transmission and reception of multi-band signals. Its effective radiation area is much larger than that of antenna mast 1, greatly enhancing signal transmission and reception capabilities, achieving longer communication distances and stronger anti-interference capabilities. This mode switching is seamless; the device does not require a restart or retest of the hardware because the bidirectional plug 6 always remains connected to the same physical interface of the device; only the internal RF path is changed.

[0029] Detailed explanation of the overall structure and linkage mechanism of the device: like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 8As shown, the main body of the device is an antenna column 1. Several receiving slots 2 are evenly arrayed circumferentially on the outer circumferential surface of the antenna column 1. A support rod 3 is rotatably connected to each receiving slot 2. Each support rod 3 is further provided with a storage slot 4. A pair of antenna rods 5 are rotatably connected to each storage slot 4.

[0030] The core actions of the device are completed in concert by the switching component 8 and the deployment component 7. Their linkage mechanism is a power transmission chain with "timing logic" to ensure the accuracy and reliability of the actions.

[0031] Step 1: Power input and signal switching (switching component 8 is working) The entire process begins with the user rotating knob 804. The rotation of knob 804 directly drives the control lever 803, which is fixed to it, to rotate synchronously. Control lever 803 and connecting rod 802 form a screw-nut mechanism, converting rotational motion into linear translation of connecting rod 802. Connecting rod 802 drives bidirectional plug 6 to move radially along antenna column 1, achieving signal path switching from "built-in enhancement" to "external enhancement." Simultaneously, control lever 803 drives rotating rod 805 to rotate via a conical wheel assembly (composed of conical wheel 1 806 and conical wheel 2 807), thereby driving the blocking component 801 to move, releasing the obstruction of the other connection end of bidirectional plug 6. At this point, signal switching is ready. Simultaneously, the rotation of rotating rod 805 serves as a power source, officially transmitting power to deployment assembly 7.

[0032] Step 2: First-stage antenna deployment (deployment support rod 3) like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 As shown, power is transmitted from the switching component 8 to the deployment component 7, initiating the physical deployment of the antenna. The top of the rotating rod 805 is fixedly connected to the drive column 703, causing the drive column 703 to rotate. The drive column 703 and the moving block 701 form a screw-nut mechanism, converting the rotational motion into the vertical lifting and lowering of the moving block 701 along the axis of the antenna column 1. The moving block 701, through the hinged connecting rod 702, synchronously pushes all the support rods 3 out of the receiving slot 2. This process is the first stage of antenna deployment, namely, the first-level deployment. In this stage, although the moving block 701 is moving, the transmission chain (i.e., rack 711 and gear 709) connecting it to the antenna column 5 deployment mechanism has not yet entered the effective meshing working range. Therefore, in this stage, only the support rods 3 are moving, and the antenna column 5 remains locked in the receiving slot 4, remaining stationary.

[0033] Step 3: Secondary antenna deployment (deploy antenna mast 5) When the support rod 3 extends to the preset angle, the moving block 701 also rises to a specific position, at which point the actual secondary extension is triggered. When the moving block 701 rises to this specific position, the rack 711 fixed to it begins to effectively mesh with the second gear 709. As the moving block 701 continues to rise, the rack 711 begins to drive the second gear 709 and the rotating column 706 to rotate. The rotation of the rotating column 706 is precisely controlled by a sophisticated "double-rope winch mechanism" to precisely control the forward and reverse rotation of the rotating shaft 704. Its detailed working principle is as follows: Structural Layout: The rotating column 706 is designed with two independent winding areas (or a single winding groove separated by a protrusion). The first end of the first traction rope 707 is fixed to one of the rotating shafts 704, and then wound clockwise around the first winding area of ​​the rotating column 706, with the last end fixed. The first end of the second traction rope 708 is fixed to the same rotating shaft 704, and then wound counterclockwise around the second winding area of ​​the rotating column 706, with the last end fixed.

[0034] Achieving forward rotation (deploying antenna masts 5): When the rotating column 706 rotates forward (e.g., clockwise) under the drive of the gear transmission mechanism (composed of gear two 709, guide cylinder 710, and rack 711), it tightens the first traction rope 707 while simultaneously releasing the second traction rope 708. The tightened first traction rope 707 generates an effective pulling force, causing the rotating shaft 704 to rotate forward, thereby driving the pair of antenna masts 5 to deploy symmetrically via gear one 705. At this time, the second traction rope 708 is in a slack state and will not cause interference.

[0035] Achieving Reversal (Retracting Antenna Moorings 5): When the user operates knob 804 in the reverse direction, all mechanisms move in the opposite direction, and the rotating column 706 rotates in the opposite direction (e.g., counterclockwise). At this time, it tightens traction rope two 708 while releasing traction rope one 707. The tightened traction rope two 708 generates a reverse pulling force, pulling the rotating shaft 704 to rotate in the opposite direction, thereby driving the pair of antenna moorings 5 ​​to be symmetrically retracted through gear one 705. At this time, traction rope one 707 is in a slack state.

[0036] Advantages: This dual-rope design, with one rope retracting and the other releasing, ensures that at any given time, only one rope provides effective driving force while the other is in a released state. It completely avoids the slack, slippage, or tangling problems that can occur when a single rope switches between forward and reverse directions, achieving precise and reliable control over the deployment and retraction angles of the antenna mast 5.

[0037] The complete workflow of the entire device is as follows: Storage state (built-in enhancement mode): The device is compact, with the connection end of the two-way plug 6 connected to the device, and the signal is enhanced through the antenna column 1.

[0038] Unfolding process: The user rotates knob 804.

[0039] Switching: Switching component 8 is activated, bidirectional plug 6 switches from connection end one to connection end two, and at the same time, shield 801 is unlocked.

[0040] First stage of deployment: Power is transmitted to the deployment component 7, the moving block 701 moves upward, and the support rod 3 is deployed through the connecting rod 702.

[0041] Secondary deployment: After the support rod 3 is deployed into place, the moving block 701 continues to move upward, driving the rotating column 706 to rotate in the forward direction through the rack 711 and the second gear 709. The rotating column 706 tightens the first traction rope 707 and releases the second traction rope 708, pulling the rotating shaft 704 to rotate in the forward direction, and finally deploys the antenna rod 5 through the first gear 705.

[0042] Deployed state (external enhancement mode): The antenna is fully deployed, and the second connection terminal of the bidirectional plug 6 is connected to the device. The signal is transmitted and received through the high-gain antenna mast 5 array.

[0043] Storage process: The user rotates knob 804 in the opposite direction, and all parts move in the opposite direction. Rotating column 706 rotates in the opposite direction, tightens traction rope 2 708, releases traction rope 1 707, pulls rotating shaft 704 to reverse, antenna mast 5 is stored first, and then support rod 3 is retracted into receiving slot 2. At the same time, bidirectional plug 6 and shield 801 are reset, completing the storage.

[0044] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the invention can be implemented in other specific forms without departing from its spirit or essential characteristics. Therefore, the embodiments should be considered in all respects as exemplary and non-limiting, and the scope of the invention is defined by the appended claims rather than the foregoing description. Thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within the present invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
