Description

Technical Field

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

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

[0003] 1. The connection method of adjacent low-frequency dipoles is mostly bolt fastening, welding or rigid clips, which requires the use of tools to position them one by one during assembly. The operation is cumbersome during disassembly. Especially during equipment maintenance or scene switching, frequent disassembly and assembly can easily cause component loss, seriously restricting the efficiency and convenience in engineering applications.

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

[0005] 3. Dipole arrays are often arranged in parallel or simple arrays, with unreasonable spacing between adjacent elements. This results in low signal coupling efficiency between the feed balun and the radiating arm, leading to signal interference and uneven radiation field distribution, affecting coverage and stability. Fourthly, the signal transmitter mounting structure is fixed, making it impossible to flexibly adjust specifications based on dipole angle changes or actual operating conditions. Furthermore, the lack of a buffer design makes it prone to poor contact or signal attenuation due to vibration.

[0006] To this end, the present invention proposes a bowl-shaped die-cast vibrator. Summary of the Invention

DETAILED DESCRIPTION

[0035] In order to make the purpose, 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 in conjunction with the drawings in the embodiments of the present disclosure. Obviously, the described embodiments are only part of the embodiments of the present disclosure, rather than all of the embodiments. The components of the embodiments of the present disclosure generally described and shown 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 for protection, but merely represents the selected embodiments of the present disclosure. Based on the embodiments of the present disclosure, all other embodiments obtained by those skilled in the art without making creative work are within the scope of protection of the present disclosure.

[0036] Example 1

[0037] refer to Figures 1-8 FIG. 1 shows a specific embodiment of a bowl-shaped die-cast vibrator according to the present invention, comprising a low-frequency dipole assembly 100 and a signal transmitter. The low-frequency dipole assembly 100 comprises 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 constitute a low-frequency dipole body. There are a plurality of low-frequency dipole bodies. A threaded seat 103 is fixed to the bottom end of each low-frequency dipole 102. The vibrator further comprises:

[0038] A disassembly assembly 200 is detachably provided at the junction of two adjacent low-frequency dipoles, and is used to "mutually lock / quickly separate" the plurality of low-frequency dipoles;

[0039] There are four low-frequency dipoles in total, and the four low-frequency dipoles are orthogonally distributed. Each low-frequency dipole 102 is provided with a set of feeding baluns and radiation arms, and a gap is left between two adjacent low-frequency dipoles.

[0040] Among them, there are four orthogonally distributed low-frequency dipoles, and the feeding balun and the radiating arm on each low-frequency dipole 102 work together. The feeding balun is responsible for balanced conversion of the signal from the signal transmitter so that the signal can be transmitted to the radiating arm more efficiently. The radiating arm radiates the converted signal into the surrounding space in the form of electromagnetic waves, thereby realizing the signal transmission function. At the same time, when there are electromagnetic waves of the corresponding frequency in the outside world, the radiating arm can also receive these electromagnetic waves, and transmit the signal to the subsequent processing circuit through the feeding balun to complete the signal reception process. The gap left between two adjacent low-frequency dipoles can reduce signal interference between each other and improve the quality of signal transmission and reception.

[0041] The disassembly assembly 200 includes a positioning component and an auxiliary component. The positioning component includes a plate body 202, and a positioning column 203 is fixed on the plate body 202. The positioning component is also provided with an auxiliary mechanism 205. The auxiliary component is provided with a positioning hole, and the positioning hole is used to cooperate with the positioning column 203 for insertion and positioning. The auxiliary component is also provided with a locking mechanism 204. The auxiliary mechanism 205 and the locking mechanism 204 are detachably connected.

[0042] When assembling adjacent low-frequency dipoles, the operator first holds the second plate 202 containing the positioning post 203 and the auxiliary assembly with the positioning hole close together. The head of the positioning post 203 is typically designed with a chamfered angle, which acts as a guide, making it easier to align the positioning post 203 with the positioning hole. Using both visual and hand guidance, the operator applies a steady thrust along the axial direction of the positioning hole, gradually inserting the positioning post 203 into the hole.

[0043] The positioning post 203 and the positioning hole have 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 clearance between the two is extremely small. This fit ensures that the positioning post 203 can be smoothly inserted into the positioning hole, and also ensures that there is no excessive shaking between the positioning post 203 and the positioning hole after insertion, thus providing a precise positioning foundation for the subsequent accurate cooperation of the auxiliary mechanism 205 and the locking mechanism 204.

[0044] The auxiliary mechanism 205 includes a bearing seat 2051 fixedly mounted on the second plate body 202, a first cavity being defined within the bearing seat 2051, a second mounting ring 2059 being fixedly connected to the inner wall of the bearing seat 2051, a through hole being defined within the second mounting ring 2059, a second abutting rod 2058 being slidably mounted on the second mounting ring 2059 through the through hole, a second spring 2054 being sleeved on the outer circumference of the second abutting rod 2058, and the second spring 2054 being located within 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 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 the upper end of the spring three 2057.

[0046] The sliding movement of abutment rod 2058 directly drives the movement of positioning sleeve 2055, which is fixed to it. Positioning sleeve 2055 moves linearly along a specific axial direction on the outer wall of support seat 2051. The outer wall of cavity 1 of support seat 2051 has also been machined with high precision, providing a stable space for the movement of positioning sleeve 2055.

[0047] The shoulder of positioning sleeve 2055 is in close contact with spring 3 2057. As positioning sleeve 2055 moves, spring 3 2057 is compressed or stretched. Spring 3 2057 serves multiple purposes. Firstly, it acts as a buffer, preventing the positioning sleeve 2055 from violent collisions during movement. Secondly, it provides a stable support force for the positioning sleeve 2055, ensuring its precise positioning during movement.

[0048] As the positioning sleeve 2055 moves, the positioning balls 2056 in the mounting grooves on its circumference also move accordingly with the movement of the positioning sleeve 2055. The positioning balls 2056 have a certain degree of freedom of movement in the mounting grooves, but this degree of freedom is strictly limited to ensure that the positioning balls 2056 do not fall out of the mounting grooves.

[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 engaged with the positioning ball 2056 in a clamping manner. The limiting body 2045 is in a "U" shape.

[0050] Among them, when the positioning sleeve 2055 moves to a suitable 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 achieve clamping. At the same time, the locking sleeve 2052 and the locking ring 2053 play a role of double insurance. 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 coming out of the limiting body 2045 due to external vibrations and other factors, thereby ensuring the stability of the clamping;

[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 with a diameter gradually decreasing from high to low in the height direction. The second abutting head is a frustum with a diameter gradually increasing from high to low in the height direction. The first abutting head and the second abutting head have the same shape and opposite directions. When the locking mechanism 204 and the auxiliary mechanism 205 are assembled and installed, the first abutting head and the second abutting head abut against each other;

[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 an operator. This external force overcomes the elastic force of the first spring 2043, causing the first abutting rod 2044 to continue to make linear sliding in the through hole of the installation ring 2042.

[0053] As the first abutting rod 2044 slides, 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, causing the second abutting rod 2058 to lose the thrust from the first abutting rod 2044. At this time, the second spring 2054 stores elastic potential energy due to being compressed before. 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 make the positioning ball 2056脱出 from the limiting body 2045.

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

[0056] It should be noted that the Chinese character "脱出" in the original text seems to be an incorrect or non-standard expression. It might be better to use a more appropriate term like "脱开" or "脱离" in a formal patent text. The translation is done based on the provided text as accurately as possible while keeping the special tags intact.In summary, first, place the two adjacent low-frequency dipoles in the appropriate position and prepare for assembly. At this time, align the positioning component and the auxiliary component of the disassembly assembly 200. The positioning post 203 is inserted into the positioning hole of the auxiliary component. This operation plays a role in preliminary positioning and ensures 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 frustum with a diameter gradually decreasing from high to low along the height direction, and the abutment head 2 is a frustum 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 accordingly. The positioning ball 2056 on the positioning sleeve 2055 moves within the installation groove. When the positioning sleeve 2055 moves to the appropriate position, the positioning ball 2056 engages with the limiting body 2045. During this process, the spring 3 2057 assists in positioning and provides buffering. The locking sleeve 2052 and the locking ring 2053 ensure that the positioning ball 2056 is stably engaged within the limiting body 2045, thereby firmly locking the two adjacent low-frequency dipoles and completing the assembly. When the two adjacent low-frequency dipoles need to be separated, a certain external force is applied to the pressing seat 2041, causing the abutment rod 1 2044 to move further, overcoming the elastic force of the spring 1 2043. The movement of the abutment rod 1 2044 changes the abutment state between the abutment joint 1 and the abutment joint 2, and the abutment rod 2 2058 slides in the opposite direction under the elastic force of the spring 2 2054. As the second 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 post 203 can be pulled out from the positioning hole, realizing the rapid separation of two adjacent low-frequency dipoles.

[0057] Example 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] An adjustment assembly 300 is provided below the low-frequency dipole component 100. The adjustment assembly 300 includes a supporting plate 301 located below the low-frequency dipole component 100. The supporting plate 301 is provided with cross-shaped through slots. A screw rod 302 is rotatably provided in each through slot. The screw rod 302 corresponds one-to-one with the threaded seat 103. The screw rod 302 is threadedly connected to the threaded seat 103. A drive assembly 303 for driving the screw rod 302 to rotate is further provided on the supporting plate 301. The drive assembly 303 is used to drive multiple low-frequency dipoles to synchronously adjust their angles and change the radiation intensity.

[0060] The driving assembly 303 includes a rotating body 305 installed on the lower end of the supporting plate 301, and a mounting sleeve 306 is fixedly provided on the inner wall of the supporting plate 301. A cavity is opened in the mounting sleeve 306, and a ring gear 3032 fixedly connected to the rotating body 305 is provided in the cavity. A mounting disk 3031 is fixedly provided on the inner wall of the ring gear 3032, and a rectangular through groove is opened in the center of the mounting disk 3031. A plurality of fixed blocks 3034 are evenly arranged along the axis on the upper end face of the mounting disk 3031, and a gear 3035 is provided on the fixed block 3034 through rotation of the rotating shaft. The plurality of gears 3035 are engaged with the ring gear 3032, and each of the gears 3035 is connected to each screw rod 302 respectively away from the axis of the rotating shaft.

[0061] The rotor 305 in the drive assembly 303 is mounted on the lower end of the carrier plate 301. When the rotor 305 is driven by an external power source, the ring gear 3032 fixed to it rotates synchronously. This is due to the fixed connection characteristics of a rigid body, and the rotor 305 and the ring gear 3032 rotate as a whole.

[0062] The inner wall of the mounting plate 3031 is fixed on the ring gear 3032, so the mounting plate 3031 will also rotate with the ring gear 3032. A gear 3035 is installed on the fixed block 3034 on the upper end face of the mounting plate 3031 through a rotating shaft, and multiple gears 3035 are all engaged with the ring gear 3032. According to the principle of gear transmission, when the ring gear 3032 rotates, it will drive the gear 3035 engaged with it to rotate around its own rotating shaft. The axis of each gear 3035 away from one end of the rotating shaft is respectively connected to each screw rod 302, so the rotation of the gear 3035 will be directly transmitted to the screw rod 302, causing the screw rod 302 to rotate in the through groove of the supporting plate 301, thereby realizing the adjustment of the angle of the low-frequency dipole. Since multiple gears 3035 are engaged with the ring gear 3032 at the same time, they will rotate synchronously, ensuring that multiple screw rods 302 are driven synchronously, so that multiple low-frequency dipoles can be adjusted in angle synchronously;

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

[0064] The transmission mechanism includes a transmission rod 3036 fixedly connected to one end of the rotating shaft away from the gear 3035, and also includes an abutment cylinder 3033. The other end of the transmission rod 3036 is rotatably provided with a transmission rod 2 3037, and the other end of the transmission rod 2 3037 is rotatably provided with a fixed shaft. The other ends of multiple fixed shafts are all connected to the outer wall of the abutment cylinder 3033. In the working state, the transmission mechanism can move in the rectangular through groove, and the abutment cylinder 3033 can reciprocate up and down in the rectangular through groove.

[0065] An abutment cap is provided at the top of the abutment tube 3033 , and the abutment cap is a frustum with a diameter gradually increasing from high to low along the height direction.

[0066] The transmission mechanism's transmission rod 1 3036 is fixedly connected to the end of the rotating shaft away from gear 3035. When gear 3035 rotates, it drives transmission rod 1 3036 in a circular motion around the rotating shaft. The other end of transmission rod 1 3036 is rotationally connected to transmission rod 2 3037, the other end of which is connected to the outer wall of abutment tube 3033 via a fixed shaft. The circular motion of transmission rod 1 3036, transmitted through transmission rod 2 3037, causes corresponding motion in abutment tube 3033.

[0067] The rectangular through groove in the center of the mounting plate 3031 provides a movable space for the transmission mechanism. In the working state, as the ring gear 3032 rotates, the linkage of the transmission rod 1 3036 and the transmission rod 2 3037 causes the abutment cylinder 3033 to reciprocate up and down in the rectangular through groove. This is because the circular motion of the transmission rod 1 3036 can be decomposed into sub-motions in the horizontal and vertical directions, and the sub-motion in the vertical direction is transmitted to the abutment cylinder 3033 through the transmission rod 2 3037, causing it to move up and down in the rectangular through groove. The abutment cap at the top of the abutment cylinder 3033 is designed as a frustum with a diameter that gradually increases from high to low in the height direction. This shape can better cooperate with other components and transmit force when the abutment cylinder 3033 moves up and down;

[0068] A mounting mechanism 304 is also fixed to the top of the mounting sleeve 306. The mounting mechanism 304 includes a fixed plate 3041 fixed to the top of the mounting sleeve 306. A cross slot 3042 is provided on the fixed plate 3041. A slot is provided on the inner wall of the cross slot 3042. A spring is provided in the slot. A plurality of bearing cylinders 3043 are provided in the cross slot 3042 so as to slide evenly along the axis of the fixed plate 3041. Under normal conditions, the plurality of bearing cylinders 3043 are close to each other, and each bearing cylinder 3043 is flexibly provided with a clamping member 3044 for mounting a launcher.

[0069] The mounting mechanism 304 includes a fixed plate 3041 secured to the top of the mounting sleeve 306. A cross-shaped slot 3042 on the fixed plate 3041 provides a sliding path for the support tubes 3043. A spring within the inner wall of the cross-shaped slot 3042 forces the multiple support tubes 3043 to move closer together under normal conditions. As the abutment tubes 3033 reciprocate up and down, the abutment caps interact with the support tubes 3043. When the abutment tubes 3033 move upward, the abutment caps compress the support tubes 3043, forcing them to slide outward within the cross-shaped slot 3042, overcoming the spring force. When the abutment tubes 3033 move downward, the spring force causes the support tubes 3043 to slide inward, returning to their normal position.

[0070] Each carrier tube 3043 includes a flexible clip 3044 for mounting a launcher. Because the carrier tube 3043 can slide within the cross slot 3042, the position of the carrier tube 3043 can be adjusted by moving the abutment tube 3033 up and down to accommodate launchers of varying sizes. This allows the clip 3044 to securely engage launchers of varying sizes, enabling flexible launcher installation.

[0071] In summary, when adjusting the angle of the low-frequency dipole, 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 with it. The mounting plate 3031 mounted on the inner wall of the ring gear 3032 also rotates accordingly. The gear 3035 on the fixed block 3034 on the mounting plate 3031 meshes with the ring gear 3032. The rotation of the ring gear 3032 drives the gear 3035 to rotate about its axis. Each gear 3035 is connected to a screw rod 302. The rotation of the gear 3035 causes the screw rod 302 to rotate within the through slot of the support plate 301. The screw rod 302 is threadedly connected to the threaded seat 103 at the bottom end of the low-frequency dipole 102, causing the threaded seat 103 to move axially along the screw rod 302, driving the low-frequency dipole 102 to rotate about the hinge point, achieving synchronous angle adjustment of multiple low-frequency dipoles and thereby changing the radiation intensity.

[0072] Regarding the transmission mechanism, transmission rod 1 3036 is fixed to the end of the rotating shaft away from gear 3035. When gear 3035 rotates, transmission rod 1 3036 performs a circular motion around the shaft. Transmission rod 1 3036 is connected to abutment cylinder 3033 via transmission rod 2 3037. This circular motion is transmitted through transmission rod 2 3037, causing abutment cylinder 3033 to reciprocate up and down within the rectangular through-slot at the center of mounting plate 3031. The abutment cap at the top of abutment cylinder 3033 assists in its coordination with other components.

[0073] Finally, regarding the mounting mechanism 304, the support tubes 3043 within the cross slots 3042 on the fixed plate 3041 are normally held together by a spring. As the abutment tube 3033 moves up and down, the abutment cap squeezes or releases the support tube 3043, causing it to slide outward or inward within the cross slots 3042, overcoming the spring force. This changes the size of the space enclosed by the support tubes 3043, and the clips 3044 within the support tube 3043 can be adjusted accordingly to accommodate transmitters of varying sizes.
