Description

Technical Field

[0001] This invention specifically relates to a two-way wireless device with a multi-segment folded adaptive antenna structure and its usage method. Background Technology

[0002] Two-way radios, also known as walkie-talkies, are mobile communication tools capable of two-way voice communication without any network support. They offer advantages such as no call charges, rapid response, and flexible use, and are widely used in public safety, emergency rescue, outdoor operations, military tactical communications, and industrial dispatching. As users' demands for portability continue to increase, two-way radio equipment is continuously developing towards miniaturization, lightweighting, and integration. As a key component in wireless communication systems for transmitting and receiving electromagnetic wave signals, the antenna not only directly determines communication quality and distance but is also often a major obstacle to the overall miniaturization of the device.

[0003] In existing technologies, the commonly used antenna types for two-way wireless devices mainly include fixed external antennas, retractable antennas, and foldable antennas. Among them, fixed external antennas have no moving parts, their shape remains unchanged, and they will not rotate or deform, giving them the advantage of high structural reliability. However, fixed antennas are always in an extended state, occupying a large space, which is extremely inconvenient when storing and carrying the device, and the protruding antenna is easily damaged by external impacts during movement or transportation.

[0004] Retractable antennas achieve length adjustment through multiple interlocking telescopic rods. When in use, they are extended to obtain a longer electrical length to ensure radiation efficiency, and retracted to reduce space occupation when stored. However, they typically only allow for longitudinal length extension and retraction. The number and length of the retractable segments are limited by the size of the device itself. The effective radiation length of the antenna in its fully extended state is often insufficient to meet the communication requirements of multi-band wide coverage. Furthermore, the telescopic structure is prone to loosening or poor contact due to mechanical wear after long-term use.

[0005] Most foldable antennas are designed to be foldable using a hinge structure. They unfold to their working position when in use and fold to reduce size when stored. Existing foldable antenna structures are mostly designed for mechanical folding and storage, and the folding direction is fixed. However, in actual use, it is often necessary to adjust the antenna's orientation to obtain a wider operating frequency range. When dealing with different usage environments, it is impossible to adjust the antenna's orientation and length in real time. As a result, the operating frequency range is still limited by the inherent geometry of the radiator, making it difficult to simultaneously meet the needs of multiple communication frequency bands.

[0006] Therefore, it is necessary to invent a two-way wireless device with a multi-segment folded adaptive antenna structure and its usage method to solve the above problems. Summary of the Invention

[0016] Preferably, the overall lengths of the secondary end telescopic sleeve, the secondary middle telescopic sleeve, and the secondary first telescopic sleeve can be matched and nested.

[0017] A method of using a two-way wireless device with a multi-segment folded adaptive antenna structure includes: S1. The secondary antenna assembly is folded and retracted step by step. The first section of the secondary telescopic sleeve is nested and retracted into the middle section of the secondary telescopic sleeve. Then, the nested and combined first section of the secondary telescopic sleeve and the middle section of the secondary telescopic sleeve are nested and retracted into the last section of the secondary telescopic sleeve. The secondary limiting rings at the top openings of the last section of the secondary telescopic sleeve and the middle section of the secondary telescopic sleeve are mutually limited with the secondary retaining rings at the bottom of the middle section of the secondary telescopic sleeve and the first section of the secondary telescopic sleeve, thus completing the overall shrinkage and positioning of the secondary antenna assembly and making the nested structures of the secondary antenna assembly fit together completely. S2. Using the secondary rotating base as the rotation reference, the secondary rotating base and the secondary rolling ring groove and secondary mounting groove formed by the secondary ball bearing, secondary rolling ring groove and secondary mounting groove between the secondary rotating base and the top of the primary telescopic sleeve drive the retracted secondary antenna assembly to rotate horizontally, adjusting the horizontal azimuth angle of the secondary antenna assembly; then, through the hinged rotating structure formed by the secondary rotating shaft, secondary fixing lug and secondary docking lug of the secondary rotating component, the secondary telescopic sleeve and the entire secondary antenna assembly are vertically flipped and folded, so that the secondary antenna assembly fits and retracts to the outside of the top of the primary antenna assembly; S3. Perform step-by-step shrinking and folding of the first-level antenna assembly. The first-level first-section telescopic sleeve is nested and folded into the first-level middle-section telescopic sleeve. Then, the nested first-level first-section telescopic sleeve and the first-level middle-section telescopic sleeve are nested and folded into the first-level last-section telescopic sleeve. The first-level limiting rings at the end openings of the first-level last-section telescopic sleeve, the first-level middle-section telescopic sleeve, and the first-level first-section telescopic sleeve mutually limit each other with the first-level retaining rings at the bottom of the first-level middle-section telescopic sleeve and the first-level first-section telescopic sleeve, thus completing the overall shrinking and positioning of the first-level antenna assembly and making the nested structures of the first-level antenna assembly completely fit and store. S4. Using the primary fixed base as a fixed reference, the rotating structure formed by the primary ball bearing, primary rolling groove, and primary mounting groove between the primary fixed base and the primary rotating base drives the retracted and folded primary antenna assembly and the retracted and fitted secondary antenna assembly to rotate horizontally synchronously to adapt to the equipment storage orientation. Then, through the hinged rotating structure formed by the primary rotating shaft, primary fixed lug, and primary docking lug of the primary rotating component, the primary end telescopic sleeve and the entire antenna structure are driven to vertically flip and fold, so that the entire antenna structure is completely retracted and fitted to the top of the two-way wireless equipment body, completing the overall folding and storage of the antenna.

[0018] Compared with the prior art, the beneficial effects of the above-mentioned technical solution of the present invention are: 1. The present invention adopts a two-level segmented and multi-section nested telescopic structure, which can shrink and nest the first-level and second-level antenna components step by step. Combined with vertical flipping and folding, the whole assembly is finally snugly packed on the top of the device body, greatly reducing the space occupied and making the device easy to carry, store and transport. 2. This invention is equipped with a double-layer ball bearing rotary structure and a hinged flipping structure. The first and second level components can be independently rotated horizontally to adjust their orientation, and can be flipped vertically to change the pitch angle. With the telescopic sleeve, the total length of the antenna can be freely adjusted. The attitude can be flexibly adjusted according to the usage scenario and signal direction to achieve adaptive signal reception and transmission. 3. Each telescopic sleeve of the present invention is equipped with a limiting ring and a retaining ring matching structure. When the sleeve is stretched or contracted, they can be locked together to limit the movement, effectively preventing the sleeve from loosening or falling off. The transmission matching between the ball ring groove and the hinge trunnion ensures smooth rotation and stable positioning, and is not prone to jamming or loosening during long-term use.

[0032] A method of using a two-way wireless device with a multi-segment folded adaptive antenna structure includes: S1. The secondary antenna assembly 4 is folded and contracted step by step. The first section telescopic sleeve 45 of the secondary stage is nested and contracted into the middle section telescopic sleeve 44 of the secondary stage. Then, the nested and combined first section telescopic sleeve 45 and middle section telescopic sleeve 44 are nested and contracted into the last section telescopic sleeve 43 of the secondary stage. The secondary limiting ring 47 at the top opening of the last section telescopic sleeve 43 and the middle section telescopic sleeve 44 of the secondary stage mutually limit each other with the secondary retaining ring 48 at the bottom of the middle section telescopic sleeve 44 and the first section telescopic sleeve 45 of the secondary stage, thus completing the overall contraction and positioning of the secondary antenna assembly 4, so that each nested structure of the secondary antenna assembly 4 is completely fitted and stored. S2. Using the secondary rotating base 41 as the rotation reference, the secondary rotating base 41 and the top of the first-stage telescopic sleeve 36 are connected by a rotating structure consisting of the secondary ball bearing 46, the secondary rolling ring groove 361, and the secondary mounting groove 411, which drives the retracted secondary antenna assembly 4 to rotate horizontally as a whole, thereby adjusting the horizontal azimuth angle of the secondary antenna assembly 4.

S3. The first-stage antenna assembly 3 is folded and retracted step by step. The first-stage first-section telescopic sleeve 36 is nested and retracted into the first-stage middle-section telescopic sleeve 35. Then, the nested first-stage first-section telescopic sleeve 36 and the first-stage middle-section telescopic sleeve 35 are nested and retracted into the first-stage last-section telescopic sleeve 34.

S4. Using the primary fixed base 31 as a fixed reference, the rotation structure formed by the primary ball bearing 37, the primary rolling ring groove 311, and the primary mounting ring groove 321 between the primary fixed base 31 and the primary rotating base 32 drives the retracted and folded overall primary antenna assembly 3 and the retracted and fitted secondary antenna assembly 4 to rotate synchronously horizontally to adapt to the equipment storage position; then, through the hinged rotation structure formed by the primary rotating shaft 333, the primary fixed ear 331, and the primary docking ear 334 of the primary rotating component 33, the primary end telescopic sleeve 34 and the overall antenna structure are driven to vertically flip and fold, so that the overall antenna structure is completely retracted and fitted to the top of the two-way wireless equipment body 1, completing the overall folding and storage of the antenna.

[0033] In this embodiment, the device includes a two-way wireless equipment body 1. An antenna structure is mounted on the top of the body 1, and a positioning clamping assembly 2 is installed on the side wall to achieve overall clamping and fixing of the device. The antenna structure consists of a primary antenna assembly 3 and a secondary antenna assembly 4 connected in sequence.

[0034] Specifically, the bottom of the primary antenna assembly 3 is a primary fixed base 31, and a primary rolling annular groove 311 is opened on the top inner side of the primary antenna assembly 3; the lower end of the primary rotating base 32 is placed inside the primary fixed base 31, and a primary mounting annular groove 321 is provided on the lower edge. Several primary balls 37 are arranged between the primary rolling annular groove 311 and the primary mounting annular groove 321. Relying on the cooperation of the balls, the primary rotating base 32 can rotate horizontally above the primary fixed base 31.

[0035] Specifically, two sets of primary fixing ears 331 are fixed to the top of the primary rotating base 32, and a primary rotating hole 332 is opened in the ear body, through which a primary rotating shaft 333 is inserted; a primary docking ear 334 is fixed to the rotating shaft 333, and the end of the docking ear 334 is fixed to the bottom of the primary end telescopic sleeve 34, thereby forming a hinge structure, which enables the primary end telescopic sleeve 34 to be vertically flipped.

[0036] Specifically, the first-stage terminal telescopic sleeve 34 is nested inside the first-stage middle telescopic sleeve 35 and the first-stage telescopic sleeve 36 in sequence; each sleeve opening is provided with a first-stage limiting ring 38, and the bottom of the first-stage middle telescopic sleeve 35 and the first-stage telescopic sleeve 36 is provided with a first-stage retaining ring 39. The retaining ring and the limiting ring are engaged with each other to prevent the sleeve from coming off when stretched, and the three sets of sleeves can be completely nested and retracted. The top of the first-stage telescopic sleeve 36 is used to install the second-stage antenna assembly 4.

[0037] Specifically, the lower end of the secondary rotating base 41 extends into the interior of the primary telescopic sleeve 36. The top of the primary telescopic sleeve 36 is provided with a secondary rolling ring groove 361, and the lower part of the secondary rotating base 41 is provided with a secondary mounting groove 411. Multiple secondary balls 46 are assembled between the two to realize the horizontal rotation of the secondary rotating base 41 on the top of the primary telescopic sleeve 36.

[0038] Specifically, the top of the secondary rotating base 41 is provided with two sets of secondary fixing ears 421, on which secondary rotating holes 422 are opened. The secondary rotating shaft 423 is installed in the holes. The rotating shaft 423 is connected to the secondary docking ear 424. The secondary docking ear 424 is fixed to the bottom of the secondary end telescopic sleeve 43, forming a hinged flip structure.

[0039] Specifically, the secondary end telescopic sleeve 43 is nested with the secondary middle telescopic sleeve 44 and the secondary first telescopic sleeve 45 in sequence; the openings of the secondary end telescopic sleeve 43 and the secondary middle telescopic sleeve 44 are provided with secondary limiting rings 47, and the bottoms of the secondary middle telescopic sleeve 44 and the secondary first telescopic sleeve 45 are provided with secondary retaining rings 48. Relying on the limiting rings and retaining rings to limit and prevent detachment, the three sets of sleeves can be nested and stored in stages.

[0040] Specifically, the folding and storage process of this device is as follows: The first section telescopic sleeve 45 of the secondary stage is nested inward into the middle section telescopic sleeve 44 of the secondary stage, and then the two are retracted together into the last section telescopic sleeve 43 of the secondary stage; the retraction and positioning of the secondary antenna assembly 4 is completed by the engagement and positioning of the secondary limit ring 47 and the secondary retaining ring 48, with each sleeve tightly fitted. Using the secondary rotating base 41 as a reference, the retracted secondary antenna assembly 4 is rotated horizontally to a specified angle by means of the rotary structure composed of the secondary ball bearing 46, the secondary rolling ring groove 361, and the secondary mounting groove 411; then, using the hinge structure of the secondary rotating part 42, the secondary antenna assembly 4 is vertically flipped, so that it is fitted and folded up on the outer side of the top of the primary antenna assembly 3. The first section telescopic sleeve 36 of the primary stage is retracted into the middle section telescopic sleeve 35 of the primary stage, and then the two are nested together into the last section telescopic sleeve 34 of the primary stage; the retraction of the primary antenna assembly 3 is completed by the mutual positioning of the primary limit ring 38 and the primary retaining ring 39, with each sleeve completely fitted. Using the primary fixed base 31 as a reference, the entire antenna structure is rotated horizontally via the primary ball bearing 37, the primary rolling ring groove 311, and the primary mounting ring groove 321 to match the storage orientation. Then, through the hinge structure of the primary rotating component 33, the primary antenna assembly 3, along with the retracted secondary antenna assembly 4, is vertically flipped, so that the entire antenna is completely attached to the top of the two-way wireless equipment body 1, completing the folding and storage operation. When the equipment is unfolded for use, the above steps are reversed to complete the sleeve stretching, angle rotation, and flipping unfolding in sequence, thus restoring the antenna to its normal working state.

[0041] In this invention, the antenna adopts a two-stage segmented and multi-section nested telescopic structure, which can shrink and nest the first-stage and second-stage antenna components step by step. With vertical flipping and folding, the entire antenna is finally snugly packed on the top of the device body, greatly reducing the space occupied and making the device easy to carry, store and transport.

[0042] In this invention, the antenna is equipped with a double-layer ball bearing rotary structure and a hinged flip structure: the primary and secondary components can be independently rotated horizontally to adjust their azimuth, and can be flipped vertically to change the elevation angle. With the telescopic sleeve, the total length of the antenna can be freely adjusted, and the attitude can be flexibly adjusted according to the usage scenario and signal direction to achieve adaptive signal reception and transmission.

[0043] In this invention, each telescopic sleeve is equipped with a limiting ring and a retaining ring matching structure. When the sleeve is stretched or contracted, they can be locked together to limit the movement, effectively preventing the sleeve from loosening or falling off. The transmission matching between the ball ring groove and the hinge trunnion ensures smooth rotation and stable positioning, and is not prone to jamming or loosening during long-term use.

[0044] In this invention, a step-by-step folding logic of first two levels and then one level is adopted. The action flow is clear and orderly, and the steps of shrinking, rotating and flipping are simple. A single person can quickly complete the antenna storage and unfolding. It has a low threshold for use and is suitable for various practical scenarios such as outdoor and work sites.

[0045] In this invention, the device sidewall is equipped with a positioning clamping component, combined with a foldable adaptive antenna, which not only ensures the normal communication function of the wireless equipment, but also takes into account the needs of installation and fixed fixation as well as flexible storage. The overall structure is compact and has a wider range of applications.

[0046] The foregoing has only described certain exemplary embodiments of the present invention by way of illustration. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the foregoing drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
