Description

Technical Field

[0001] The present invention relates to the technical field of wireless communication devices, and more particularly to a bowl-shaped die-cast oscillator. Background Art

[0002] In the fields of wireless communication and signal processing, low-frequency dipole antenna devices, as core components, are widely used in scenarios such as broadcast transmission, navigation and positioning, radar detection, and base station communication. Such devices usually achieve directional radiation and intensity adjustment of signals through the combined layout of multiple low-frequency dipoles, and their structural design directly affects the installation convenience, signal transmission efficiency, and environmental adaptability of the device. Traditional low-frequency dipole antenna devices mainly consist of dipole components, adjustment mechanisms, and transmitter installation structures, and their core functions rely on the angle adjustment and modular connection of dipoles. However, the existing technology has the following significant defects:

[0003] 1. The connection methods between adjacent low-frequency dipoles mostly use bolt fastening, welding, or rigid buckles, resulting in the need to use tools for positioning one by one during assembly, and the operation is cumbersome during disassembly. Especially during equipment maintenance or scenario switching, frequent disassembly and assembly are likely to cause component loss, seriously restricting the efficiency and convenience in engineering applications.

[0004] 2. The angle adjustment mechanism usually adopts an independent drive mode, with asynchronous adjustment and poor accuracy of each dipole, and the transmission structure is complex and vulnerable to external interference, making it difficult to dynamically adjust the signal radiation intensity according to actual needs.

[0005] 3. The dipole layout is mostly parallel or a simple array, with unreasonable spacing between adjacent units, and low signal coupling efficiency between the feed balun and the radiation arm, resulting in signal interference with each other, uneven radiation field distribution, affecting the coverage range and stability. Fourth, the signal transmitter installation structure is fixed, unable to flexibly adjust the specifications according to the angle change of the dipole or the actual working conditions, and lacking a buffer design, it is easy to cause poor contact or signal attenuation due to vibration.

[0006] Therefore, the present invention proposes a bowl-shaped die-cast oscillator. Summary of the Invention

The first abutting head and the second abutting head have the same shape but opposite directions.

Detailed implementation manners

[0035] To make the objectives, technical solutions and advantages of the embodiments of the present disclosure clearer, the technical solutions in the embodiments of the present disclosure will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present disclosure. Obviously, the described embodiments are only a part of the embodiments of the present disclosure, rather than all the embodiments. Usually, the components of the embodiments of the present disclosure described and illustrated here can be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiments of the present disclosure is not intended to limit the scope of the present disclosure claimed, but only represents the selected embodiments of the present disclosure. All other embodiments obtained by those skilled in the art based on the embodiments of the present disclosure without creative efforts belong to the scope of protection of the present disclosure.

[0036] Embodiment 1

[0037] Refer to Figures 1-8 As shown, a specific implementation manner of a bowl-shaped die-cast oscillator of the present invention includes a low-frequency dipole component 100 and a signal transmitter. The low-frequency dipole component 100 includes a mounting body 101 and a low-frequency dipole 102 that are hinged to each other. The mounting body 101 and the low-frequency dipole 102 form a low-frequency dipole body. There are multiple low-frequency dipole bodies. A threaded seat 103 is fixedly provided at the bottom end of each low-frequency dipole 102. Further included are:

[0038] Disassembly assembly 200, the disassembly assembly 200 is detachably arranged at the junction of two adjacent low-frequency dipoles, and the disassembly assembly 200 is used for "mutual locking / quick separation" between multiple low-frequency dipoles in pairs;

[0039] There are four low-frequency dipoles in total, and the four low-frequency dipoles are orthogonally distributed. A set of feed balun and radiation arms are arranged on each low-frequency dipole 102, and there is a gap between two adjacent low-frequency dipoles.

[0040] Among them, for the four orthogonally distributed low-frequency dipoles, the feed balun and radiation arms on each low-frequency dipole 102 work together. The feed balun is responsible for balancing and converting the signal of the signal transmitter so that the signal can be transmitted to the radiation arm more effectively. The radiation arm radiates the converted signal into the surrounding space in the form of electromagnetic waves to achieve the signal emission function. At the same time, when there are electromagnetic waves with corresponding frequencies in the outside world, the radiation arm can also receive these electromagnetic waves and transmit the signal to the subsequent processing circuit through the feed balun to complete the signal reception process. The gap left between two adjacent low-frequency dipoles can reduce the signal interference between them and improve the quality of signal emission and reception.

[0041] The disassembly assembly 200 includes a positioning component and an auxiliary component. The positioning component includes a second plate 202, and a positioning post 203 is fixedly arranged on the second plate 202. An auxiliary mechanism 205 is also arranged on the positioning component. A positioning hole is formed on the auxiliary component, and the positioning hole is used for mating and inserting with the positioning post 203 for positioning. A locking mechanism 204 is also arranged on the auxiliary component, and the auxiliary mechanism 205 and the locking mechanism 204 are detachably connected.

[0042] Among them, when starting to assemble adjacent low-frequency dipoles, the operator first holds the second plate 202 containing the positioning post 203 and the part of the auxiliary component with the positioning hole and approaches them. Since the head of the positioning post 203 is usually designed with a certain chamfer, this chamfer design is like a guiding mark, making the positioning post 203 more easily aligned with the positioning hole. With the dual assistance of vision and touch, the operator applies a stable thrust along the axial direction of the positioning hole to gradually insert the positioning post 203 into the positioning hole.

[0043] The positioning post 203 and the positioning hole are in a precisely designed clearance fit. The outer diameter of the positioning post 203 is slightly smaller than the inner diameter of the positioning hole, and the gap between them is extremely small. Such a fit method can not only ensure that the positioning post 203 can be smoothly inserted into the positioning hole, but also ensure that there will be no excessive shaking between the positioning post 203 and the positioning hole after insertion, thus providing an accurate position basis for the accurate cooperation of the subsequent auxiliary mechanism 205 and the locking mechanism 204;

[0044] The auxiliary mechanism 205 includes a bearing seat 2051 fixedly arranged on the second plate body 202, a first cavity is provided in the bearing seat 2051, a second mounting ring 2059 fixedly connected to the inner wall of the bearing seat 2051 is provided in the first cavity, a through hole is provided on the second mounting ring 2059, a second abutting rod 2058 is slidably arranged on the second mounting ring 2059 through the through hole, a second spring 2054 is sleeved on the outer circumference of the second abutting rod 2058, and the second spring 2054 is located in the first cavity;

[0045] A positioning sleeve 2055 is fixedly provided on the spring two 2054, and a shoulder is provided on the positioning sleeve 2055. A spring three 2057 is sleeved on the outer circumference of the positioning sleeve 2055, and the bottom end of the spring three 2057 abuts against the shoulder of the positioning sleeve 2055. A plurality of mounting grooves are provided on the circumference of the positioning sleeve 2055, and positioning balls 2056 are movably provided in the plurality of mounting grooves. A locking sleeve 2052 is slidably provided on the outer circumference of the shoulder of the positioning sleeve 2055, and a locking ring 2053 is fixedly provided on the inner wall of the locking sleeve 2052, and the bottom end face of the locking ring 2053 abuts against the upper end of the spring three 2057.

[0046] The sliding of the abutment rod 2058 directly drives the positioning sleeve 2055 fixedly connected thereto to move. The positioning sleeve 2055 moves linearly along a specific axial direction on the outer wall of the bearing seat 2051. The outer wall of the cavity 1 of the bearing seat 2051 is also processed with high precision, providing a stable space environment for the movement of the positioning sleeve 2055.

[0047] The shoulder of the positioning sleeve 2055 is in close contact with the spring three 2057. When the positioning sleeve 2055 moves, the spring three 2057 will be compressed or stretched. The role of the spring three 2057 is multifaceted. On the one hand, it plays a buffering role to prevent the positioning sleeve 2055 from producing a violent collision during the movement; on the other hand, it can provide a stable supporting force for the positioning sleeve 2055 to ensure the position accuracy of the positioning sleeve 2055 during the movement.

[0048] During the movement of the positioning sleeve 2055, the positioning ball 2056 in the mounting groove on its peripheral surface will also produce corresponding displacement along with the movement of the positioning sleeve 2055. The positioning ball 2056 has a certain degree of freedom of movement in the mounting groove, but this degree of freedom is strictly limited to ensure that the positioning ball 2056 will not fall out of the mounting groove.

[0049] The auxiliary component includes a first plate body 201 and a pressing seat 2041 fixedly arranged on the first plate body 201. A second cavity is formed in the pressing seat 2041. An installation ring 2042 is fixedly arranged on the inner wall of the pressing seat 2041. Through holes are formed in the installation ring 2042. A first abutting rod 2044 is slidably arranged on the installation ring 2042 through the through holes. A first spring 2043 is sleeved on the outer peripheral surface of the first abutting rod 2044. The first spring 2043 is located in the second cavity. The bottom end of the pressing seat 2041 is fixedly provided with a limiting body 2045 which is in interference fit with the positioning ball 2056. The limiting body 2045 is in a "U" shape.

[0050] Among them, when the positioning sleeve 2055 moves to a proper position, the positioning ball 2056 just aligns with the "U" shaped structure of the limiting body 2045. Under the elastic force of the third spring 2057, the positioning ball 2056 will be tightly pressed into the "U" shaped structure of the limiting body 2045 to realize interference fit. At the same time, the locking sleeve 2052 and the locking ring 2053 play a dual insurance role. The locking sleeve 2052 slides along the outer peripheral surface of the shoulder of the positioning sleeve 2055. The locking ring 2053 is in close contact with the upper end of the third spring 2057 to limit the position of the positioning ball 2056 and prevent the positioning ball 2056 from disengaging from the limiting body 2045 due to external vibration and other factors, so as to ensure the stability of the interference fit;

[0051] A first abutting head is fixedly arranged at one end of the first abutting rod 2044 away from the installation ring 2042. A second abutting head is fixedly arranged at one end of the second abutting rod 2058 away from the second installation ring 2059. The first abutting head is a frustum of a cone with a gradually decreasing diameter from high to low in the height direction. The second abutting head is a frustum of a cone with a gradually increasing diameter from high to low in the height direction. The first abutting head and the second abutting head have the same shape but opposite directions. When the locking mechanism 204 and the auxiliary mechanism 205 are assembled, the first abutting head and the second abutting head are in mutual abutment;

[0052] Among them, when it is necessary to separate adjacent low-frequency dipoles, an external force in the opposite direction to the assembly is applied to the pressing seat 2041 by the operator. This external force overcomes the elastic force of the first spring 2043, so that the first abutting rod 2044 continues to make linear sliding in the through hole of the installation ring 2042.

[0053] With the sliding of the first abutting rod 2044, the abutting state between the first abutting head and the second abutting head changes. The first abutting head gradually moves away from the second abutting head, so that the second abutting rod 2058 loses the thrust from the first abutting rod 2044. At this time, since the second spring 2054 was compressed before and stored elastic potential energy, under the action of this elastic potential energy, the second spring 2054 pushes the second abutting rod 2058 to make reverse linear sliding in the through hole of the second installation ring 2059.

[0054] The reverse sliding of the second abutting rod 2058 drives the positioning sleeve 2055 to move in the reverse direction. As the positioning sleeve 2055 moves in the reverse direction, the constraint on the positioning ball 2056 from the limiting body 2045 gradually decreases. When the positioning sleeve 2055 moves to a certain position, the frictional force and clamping force between the positioning ball 2056 and the "U"-shaped structure of the limiting body 2045 are insufficient to maintain the clamped state. At this time, the operator only needs to apply a slight external force to disengage the positioning ball 2056 from the limiting body 2045.

[0055] After the positioning ball 2056 is disengaged, the locking state between two adjacent low-frequency dipoles is released. The operator can directly hold the second plate body 202 where the positioning post 203 is located or related components, and apply a pulling force along the axial direction of the positioning hole to pull out the positioning post 203 from the positioning hole. During the pulling-out process, the clearance fit between the positioning post 203 and the positioning hole makes the pulling-out process relatively smooth, and finally realizes the separation of two adjacent low-frequency dipoles.

[0056] In summary, first, place two adjacent low-frequency dipoles in a suitable position and prepare for assembly. At this time, align the positioning assembly and the auxiliary assembly of the disassembly assembly 200. The positioning column 203 is inserted into the positioning hole of the auxiliary assembly. This operation plays a role of preliminary positioning to ensure that the relative positions of the two low-frequency dipoles are accurate. Then, the auxiliary mechanism 205 and the locking mechanism 204 are matched and installed. During the installation process, the abutment head 1 and the abutment head 2 abut each other. Since the abutment head 1 is a truncated cone with a diameter gradually decreasing from high to low along the height direction, and the abutment head 2 is a truncated cone with a diameter gradually increasing from high to low along the height direction, and the two are of the same shape and opposite directions, when they abut each other, the abutment rod 1 2044 will push the abutment rod 2 2058 to slide in the through hole of the mounting ring 2 2059. The sliding of the abutment rod 2 2058 will compress the spring 2 2054, and the positioning sleeve 2055 will also move therewith. The positioning ball 2056 on the positioning sleeve 2055 moves in the installation groove. When the positioning sleeve 2055 moves to a suitable position, the positioning ball 2056 will be engaged with the limiting body 2045. In this process, the spring three 2057 plays a role of auxiliary positioning and buffering. The locking sleeve 2052 and the locking ring 2053 ensure that the positioning ball 2056 is stably engaged in the limiting body 2045, thereby realizing the firm locking of two adjacent low-frequency dipoles and completing the assembly; when it is necessary to separate the two adjacent low-frequency dipoles, a certain external force is applied to the pressing seat 2041, so that the abutting rod 1 2044 overcomes the elastic force of the spring 1 2043 and moves further. The movement of the abutting rod 1 2044 will change the abutting state between the abutting head 1 and the abutting head 2, and the abutting rod 2 2058 slides in the opposite direction under the elastic force of the spring 2 2054. As the abutment rod 2058 slides, the positioning sleeve 2055 also moves in the opposite direction, and the positioning ball 2056 escapes from the limiting body 2045, releasing the clamping state. At this time, the positioning column 203 can be pulled out from the positioning hole, realizing the rapid separation of two adjacent low-frequency dipoles.

[0057] Embodiment 2

[0058] Please refer to Figures 1-8 This embodiment is basically the same as the first embodiment. This embodiment is made on the basis of the first embodiment and has the same beneficial effects as the first embodiment. The same parts can be referred to each other and will not be described in detail here.

[0059] Adjustment assembly 300, the adjustment assembly 300 is arranged below the low-frequency dipole assembly 100. The adjustment assembly 300 includes a carrier plate 301 located below the low-frequency dipole assembly 100. A cross-shaped distribution of through slots is provided on the carrier plate 301. A lead screw 302 is rotatably provided in each through slot. The lead screws 302 correspond to the threaded seats 103 one by one. The lead screw 302 is threadedly connected to the threaded seat 103. The carrier plate 301 is further provided with a drive assembly 303 for driving the lead screw 302 to rotate. The drive assembly 303 is used to drive multiple low-frequency dipoles to synchronously adjust the angle and change the radiation intensity;

[0060] The drive assembly 303 includes a rotating body 305 installed at the lower end of the carrier plate 301. An installation sleeve 306 is fixedly provided on the inner wall of the carrier plate 301. A cavity is provided in the installation sleeve 306. A ring gear 3032 fixedly connecting the rotating body 305 is provided in the cavity. An installation disk 3031 is fixedly provided on the inner wall of the ring gear 3032. A rectangular through slot is provided at the center of the installation disk 3031. A plurality of fixing blocks 3034 are uniformly arranged along the axis on the upper end surface of the installation disk 3031. A gear 3035 is rotatably provided on the fixing block 3034 through a rotating shaft. A plurality of the gears 3035 are all engaged with the ring gear 3032. The axis of each gear 3035 away from the rotating shaft is respectively connected to each lead screw 302.

[0061] Among them, the rotating body 305 in the drive assembly 303 is installed at the lower end of the carrier plate 301. When the rotating body 305 is driven by an external power source to rotate, the ring gear 3032 fixedly connected thereto will rotate synchronously. This is based on the fixed connection characteristic of a rigid body. The rotating body 305 and the ring gear 3032 rotate as a whole.

[0062] The inner wall of the installation disk 3031 is fixed to the ring gear 3032. Therefore, the installation disk 3031 will also rotate with the ring gear 3032. A gear 3035 is installed on the fixing block 3034 on the upper end surface of the installation disk 3031 through a rotating shaft. A plurality of the gears 3035 are all engaged with the ring gear 3032. According to the gear transmission principle, when the ring gear 3032 rotates, it will drive the engaged gear 3035 to rotate around its own rotating shaft. The axis of each gear 3035 away from the rotating shaft is respectively connected to each lead screw 302. Therefore, the rotation of the gear 3035 will be directly transmitted to the lead screw 302, causing the lead screw 302 to rotate in the through slot of the carrier plate 301, thereby realizing the adjustment of the angle of the low-frequency dipole. Since a plurality of the gears 3035 are simultaneously engaged with the ring gear 3032, they will rotate synchronously, ensuring that a plurality of lead screws 302 are synchronously driven, enabling a plurality of low-frequency dipoles to synchronously adjust the angle;

[0063] The driving component 303 further includes a transmission mechanism that rotates through the ring gear 3032 to perform reciprocating up and down motion. The transmission mechanism is located in the cavity of the mounting sleeve 306;

[0064] The transmission mechanism includes a first transmission rod 3036 fixedly connected to one end of the rotating shaft away from the gear 3035, and further includes an abutting cylinder 3033. The other end of the first transmission rod 3036 is rotatably provided with a second transmission rod 3037. The other end of the second transmission rod 3037 is rotatably provided with a fixed shaft. The other ends of multiple fixed shafts are all connected to the outer wall of the abutting cylinder 3033. In the working state, the transmission mechanism can move in the rectangular through groove, and the abutting cylinder 3033 reciprocates up and down in the rectangular through groove.

[0065] The top end of the abutting cylinder 3033 is provided with an abutting cap, and the abutting cap is a frustum of a cone with a diameter gradually increasing from high to low in the height direction.

[0066] Among them, the first transmission rod 3036 of the transmission mechanism is fixedly connected to one end of the rotating shaft away from the gear 3035. When the gear 3035 rotates, it will drive the first transmission rod 3036 to perform circular motion around the rotating shaft. The other end of the first transmission rod 3036 is rotatably connected to the second transmission rod 3037, and the other end of the second transmission rod 3037 is connected to the outer wall of the abutting cylinder 3033 through a fixed shaft. Due to the circular motion of the first transmission rod 3036, through the transmission of the second transmission rod 3037, the abutting cylinder 3033 will generate corresponding motion.

[0067] The rectangular through groove at the center of the mounting disc 3031 provides a moving space for the transmission mechanism. In the working state, as the ring gear 3032 rotates, the linkage of the first transmission rod 3036 and the second transmission rod 3037 causes the abutting cylinder 3033 to reciprocate up and down in the rectangular through groove. This is because the circular motion of the first transmission rod 3036 can be decomposed into horizontal and vertical component motions, and the vertical component motion is transmitted to the abutting cylinder 3033 through the second transmission rod 3037, causing it to move up and down in the rectangular through groove. The abutting cap at the top end of the abutting cylinder 3033 is designed as a frustum of a cone with a diameter gradually increasing from high to low in the height direction. This shape can better cooperate with other components and transmit force when the abutting cylinder 3033 moves up and down;

[0068] The top end of the installation sleeve 306 is also fixedly provided with an installation mechanism 304. The installation mechanism 304 includes a fixed disk 3041 fixedly arranged at the top end of the installation sleeve 306. A cross-shaped chute 3042 is formed on the fixed disk 3041. The inner wall of the cross-shaped chute 3042 is provided with a chute, and a spring is arranged in the chute. A plurality of bearing cylinders 3043 are evenly slidably arranged along the axis of the fixed disk 3041 in the cross-shaped chute 3042. Under normal conditions, the plurality of bearing cylinders 3043 approach each other. A clamping member 3044 for installing a transmitter is flexibly arranged in each bearing cylinder 3043;

[0069] Among them, the fixed disk 3041 of the installation mechanism 304 is fixed at the top end of the installation sleeve 306. The cross-shaped chute 3042 on the fixed disk 3041 provides a sliding path for the bearing cylinders 3043. The springs in the chutes on the inner wall of the cross-shaped chute 3042 make the plurality of bearing cylinders 3043 approach each other under normal conditions. When the abutting cylinder 3033 reciprocates up and down, the abutting cap will interact with the bearing cylinder 3043. When the abutting cylinder 3033 moves upward, the abutting cap will squeeze the bearing cylinder 3043, causing the bearing cylinder 3043 to slide outward in the cross-shaped chute 3042 against the elastic force of the spring; when the abutting cylinder 3033 moves downward, the elastic force of the spring will cause the bearing cylinder 3043 to slide inward and return to the normal position.

[0070] The clamping member 3044 flexibly arranged in each bearing cylinder 3043 is used to install the transmitter. Since the bearing cylinder 3043 can slide in the cross-shaped chute 3042, the position of the bearing cylinder 3043 can be adjusted by the up and down movement of the abutting cylinder 3033 according to the size of different transmitters, so that the clamping member 3044 can firmly clamp transmitters of different specifications, realizing the flexible installation of the transmitter;

[0071] In summary, first, when adjusting the angle of the low-frequency dipole, the external power drives the rotating body 305 to rotate. Since the rotating body 305 is fixedly connected to the ring gear 3032, the ring gear 3032 rotates synchronously. The mounting disk 3031 installed on the inner wall of the ring gear 3032 also rotates accordingly. The gear 3035 on the fixed block 3034 on the mounting disk 3031 meshes with the ring gear 3032, and the rotation of the ring gear 3032 drives the gear 3035 to rotate around the axis. Each gear 3035 is connected to a lead screw 302. The rotation of the gear 3035 makes the lead screw 302 rotate in the through groove of the bearing plate 301. The lead screw 302 is threadedly connected to the threaded seat 103 at the bottom end of the low-frequency dipole 102, so that the threaded seat 103 moves along the axial direction of the lead screw 302, driving the low-frequency dipole 102 to rotate around the hinge point, realizing the synchronous angle adjustment of multiple low-frequency dipoles, and further changing the radiation intensity.

[0072] Then, in terms of the transmission mechanism, the first transmission rod 3036 is fixed to the end of the rotating shaft away from the gear 3035. When the gear 3035 rotates, the first transmission rod 3036 makes a circular motion around the axis. The first transmission rod 3036 is connected to the abutting cylinder 3033 through the second transmission rod 3037. This circular motion is transmitted through the second transmission rod 3037, causing the abutting cylinder 3033 to make a reciprocating up-and-down motion in the rectangular through groove at the center of the mounting plate 3031. The abutting cap at the top of the abutting cylinder 3033 assists it in cooperating with other components.

[0073] Finally, for the mounting mechanism 304, the bearing cylinders 3043 in the cross-shaped sliding grooves 3042 on the fixed plate 3041 approach each other under the action of the spring under normal conditions. When the abutting cylinder 3033 moves up and down, the abutting cap will squeeze or release the bearing cylinders 3043, causing the bearing cylinders 3043 to slide outward against the spring force in the cross-shaped sliding grooves 3042 or slide inward under the action of the spring force, thereby changing the size of the space enclosed by the bearing cylinders 3043. The clamping members 3044 in the bearing cylinders 3043 can be adjusted accordingly to adapt to the installation of transmitters of different sizes.
