Description

Technical Field

[0001] The utility model relates to the technical field of dual-antenna products, in particular to a dual-antenna intercom based on Beidou positioning. Background Art

[0002] In modern communication and positioning systems, accuracy and signal stability are crucial. The dual-antenna system, by utilizing two receiving modules to receive signals from the same signal source, can significantly improve the accuracy and reliability of signal reception. Especially in applications based on the Beidou positioning system, the dual-antenna configuration can effectively reduce the signal shielding, multipath effects and other problems that a single antenna may encounter by comparing or integrating the signals received by the two antennas, thereby improving positioning accuracy and system stability. In addition, the dual-antenna system can also provide technical support for high-dynamic, high-precision positioning, meeting the needs of specific fields such as navigation and unmanned driving, which have higher requirements for positioning accuracy and stability.

[0003] However, in the prior art, dual-antenna systems usually face an important limitation - the relative position between the two antennas is fixed and cannot be adjusted according to the actual situation of the received signal. The disadvantage of this design is that when the signal environment changes, or when the antenna spacing needs to be adjusted to optimize the signal reception quality in a specific application scenario, the fixed antenna configuration cannot be flexibly adapted, which may lead to reduced accuracy and stability of signal reception. For example, in densely populated urban areas or indoor environments, signal reflection and interference are more serious, and a fixed-distance dual-antenna configuration may not achieve the best signal processing effect. Therefore, the prior art has obvious deficiencies in providing high flexibility and adaptability, which limits the application potential of dual-antenna systems in complex environments. Utility Model Content

[0004] The main purpose of the utility model is to propose a dual-antenna walkie-talkie based on Beidou positioning, aiming to solve the technical problem that the prior art cannot adjust the position between the two antennas according to actual usage.

[0006] In a possible implementation, the first frame is provided with a guide rail extending in the length direction of the first frame, and a slide is provided at the bottom of the first antenna, and the slide is slidably connected to the guide rail to drive the first antenna to move in the length direction of the guide rail.

[0007] In a possible implementation, the guide rail is disposed on the top of the first frame;

[0008] The slide seat is movably arranged in the height direction of the guide rail, and has a sliding position away from the top of the first frame, and a fixed position close to the top of the first frame. When the slide seat is in the sliding position, the slide seat can slide in the length direction of the guide rail.

[0010] The slide seat comprises two support arms arranged on opposite sides of the vertical arm, and a connecting arm arranged on the side of the horizontal arm facing away from the first frame body, the connecting arms are respectively connected to the two support arms, and a clamping piece is arranged on the side of each support arm close to the corresponding clamping slot, and the clamping piece is inserted into the corresponding clamping slot;

[0011] The depth of the clamping groove in the height direction of the vertical arm is greater than the width of the corresponding clamping piece in the height direction of the vertical arm, so that the clamping piece can be moved in the height direction of the vertical arm. In the sliding position, the clamping piece can be slidably abutted against the cross arm. In the fixed position, the clamping piece or the support arm is removably fixed to the top of the first frame.

[0012] In a possible implementation, two first magnetic members are disposed on the top of the first frame, and the two first magnetic members are respectively disposed on opposite sides of the vertical arm, and each of the first magnetic members extends in the same direction as the vertical arm;

[0014] In a possible implementation manner, the outer surface of each of the clamping parts is an arc surface;

[0015] The groove surface of each of the clamping grooves is an arc surface.

[0016] The dual-antenna intercom based on Beidou positioning of the utility model has the following advantages:

[0017] First of all, the dual-antenna configuration allows the body to receive more stable and accurate signals in complex environments. Through the interaction of the two antennas, the impact of signal shielding and multipath effects can be effectively reduced, thereby improving positioning accuracy.

[0018] Secondly, the design of the bracket assembly, including the relative layout of the first frame and the second frame, not only enhances the structural stability of the entire device, but also its characteristic of extending in directions away from each other provides a physical basis for adjusting the antenna spacing, further enhancing the adaptability and positioning accuracy of the system in different environments.

[0019] Furthermore, by arranging a guide rail on the first frame and slidingly connecting the slide seat to the guide rail, the first antenna can be moved in the length direction of the guide rail, which not only simplifies the operation process of adjusting the antenna position, but also makes it possible to flexibly adjust the antenna position according to signal strength and other external conditions, thereby achieving the best signal reception effect. The design of arranging the guide rail on the top of the first frame further optimizes the stability and accuracy of the antenna movement, and the movable setting of the slide seat in the height direction increases the flexibility of operation, allowing the user to easily adjust the position of the antenna according to actual needs.

[0020] In addition, the design of the vertical arm and the horizontal arm not only provides a stable support structure for the antenna, but also the clamping groove formed by them together provides an innovative solution for the positioning and fixing of the slide. Through the interaction between the clamping piece and the clamping groove, the position of the antenna can be flexibly adjusted in different height directions, and fast switching between the sliding position and the fixed position can be achieved. This design greatly improves the convenience of users to adjust the antenna position and the flexibility of the system.

[0021] The introduction of magnetic parts provides a simple and effective solution for the stable fixation of the antenna. The magnetic connection between the first magnetic part and the second magnetic part not only ensures that the antenna can be stably fixed in the desired position after adjustment, but also the easy operability of the magnetic connection further improves the user-friendliness of the entire system. Finally, the design of the convex arc surface of the snap-in part and the concave arc surface of the snap-in groove ensures a smooth transition and precise docking when adjusting the antenna position, reduces friction and wear during operation, extends the service life of the equipment, and also ensures the accuracy and stability of the antenna position adjustment.

[0031] The utility model provides a dual-antenna intercom based on Beidou positioning.

[0032] In the embodiment of the present utility model, Figure 1 to Figure 2 As shown, the dual-antenna walkie-talkie based on Beidou positioning includes a body 1, a bracket assembly 2 and an antenna assembly 3; the bracket assembly 2 includes a first frame 21 and a second frame 22, the first frame 21 is arranged on a side of the body 1, and the second frame 22 is arranged on the side of the body 1 facing away from the first frame 21, and the first frame 21 and the first frame 21 extend in directions away from each other; the antenna assembly 3 includes a first antenna 31 and a second antenna 32, both of which are configured with a receiving module for receiving Beidou signals, the first antenna 31 is movably arranged on the first frame 21, and the second antenna 32 is movably arranged on the second frame 22.

[0033] By arranging the first frame 21 and the second frame 22 in opposite directions, a physical basis is provided for adjusting the distance between the first antenna 31 and the second antenna 32. By adjusting the distance between the first antenna 31 and the second antenna 32, signal reception can be optimized according to the quality of the received signal and environmental conditions, which is particularly important in signal-blocked areas such as densely populated cities or mountainous areas.

[0034] The first frame 21 is provided with a guide rail 4 extending in the length direction of the first frame 21 . A slide seat 5 is provided at the bottom of the first antenna 31 . The slide seat 5 is slidably connected to the guide rail 4 to drive the first antenna 31 to move in the length direction of the guide rail 4 .

[0035] By introducing the guide rail 4 and the slide seat 5 slidably connected thereto, a precise and controllable movement mode is provided for the first antenna 31. This design enables the first antenna 31 to move smoothly along the length direction of the guide rail 4, thereby achieving fine adjustment of the antenna position.

[0036] The mechanism for realizing the linear reciprocating movement generally includes but is not limited to the guide rail 4 cooperating with a slider, a linear bearing or a ball screw, etc. In the embodiment, the sliding connection between the slide 5 and the guide rail 4 provides a simple and effective structure for realizing the linear movement of the first antenna 31. This design not only increases the flexibility of the device, allowing the user to adjust the antenna position according to the receiving conditions to optimize the signal reception, but also simplifies the mechanical structure of the antenna adjustment, improves the reliability and ease of use. Through such a structural arrangement, the user can more conveniently adjust the antenna spacing according to the specific use environment and signal conditions, so as to achieve the best signal reception effect in different scenarios.

[0037] The guide rail 4 is disposed on the top of the first frame 21;

[0038] The slide 5 is movably arranged in the height direction of the guide rail 4, and has a sliding position away from the top of the first frame 21, and a fixed position close to the top of the first frame 21. When the slide 5 is in the sliding position, the slide 5 can slide in the length direction of the guide rail 4. When the slide 5 is in the fixed position, the slide 5 and the first frame 21 can be detachably fixed.

[0039] This embodiment introduces a height-adjustable slide 5, which provides greater flexibility for adjusting the position of the antenna. By setting the guide rail 4 on the top of the first frame 21 and allowing the slide 5 to move to different positions (sliding position and fixed position) in the height direction, the first antenna 31 is adjustable not only in the length direction of the guide rail 4 but also in the height direction of the guide rail 4. This design allows the user to adjust not only the lateral distance between the antennas but also the height of the antenna according to specific receiving conditions, thereby optimizing the signal reception performance in three-dimensional space.

[0040] In addition, when the slide 5 is adjusted to a fixed position, the slide 5 and the first frame 21 can be fixed by a magnetic connection or a latch mechanism, thereby ensuring the stability of the first antenna 31 at a specific position.

[0041] The guide rail 4 includes a vertical arm 41 and a horizontal arm 42. One end of the vertical arm 41 is fixed to the top of the first frame 21, and the other end of the vertical arm 41 is connected to the horizontal arm 42. The first frame 21, the vertical arm 41 and the horizontal arm 42 are together enclosed to form two clamping grooves 43. The two clamping grooves 43 are respectively located on opposite sides of the vertical arm 41.

[0042] The slide 5 includes two support arms 51 disposed on opposite sides of the vertical arm 41, and a connecting arm 52 disposed on the side of the horizontal arm 42 facing away from the first frame 21. The connecting arm 52 is connected to the two support arms 51 respectively. A clamping member 53 is disposed on the side of each support arm 51 close to the corresponding clamping groove 43. The clamping member 53 is inserted into the corresponding clamping groove 43.

[0043] The depth of the snap-in groove 43 in the height direction of the vertical arm 41 is greater than the width of the corresponding snap-in piece 53 in the height direction of the vertical arm 41, so that the snap-in piece 53 can be moved in the height direction of the vertical arm 41. In the sliding position, the snap-in piece 53 can be slidably abutted against the cross arm 42. In the fixed position, the snap-in piece 53 or the support arm 51 is removably fixed to the top of the first frame 21.

[0044] The clip 53 of each support arm 51 is inserted into the corresponding clip groove 43. This insertion method makes it possible for the slide 5 to move in the height direction of the vertical arm 41, while ensuring the stability of the slide 5 during the height adjustment process. The depth of the clip groove 43 is greater than the width of the clip 53 in the height direction of the vertical arm 41. This design allows the clip 53 to slide in the height direction of the vertical arm 41 while limiting the movement range of the clip 53, ensuring that the clip 53 always maintains an effective connection with the clip groove 43, thereby preventing the slide 5 from falling off when adjusting the height.

[0045] In other embodiments, the engaging groove 43 may be provided only on one side of the guide rail 4 , and the other side of the guide rail 4 may be designed as a plane.

[0046] The feature is that two first magnetic members 211 are disposed on the top of the first frame 21, and the two first magnetic members 211 are disposed on opposite sides of the vertical arm 41, and each first magnetic member 211 extends in the same direction as the vertical arm 41;

[0047] Each support arm 51 is provided with a second magnetic member 54 . The second magnetic member 54 is magnetically connected to the first side member on the corresponding side so as to fix the support arm 51 on the top of the first frame 21 .

[0048] By arranging magnetic suction parts on the top of the first frame 21 and the support arm 51, a quick fixing method is achieved without the need for a complex mechanical locking mechanism. The magnetic connection provides great convenience for the quick deployment and adjustment of the first antenna 31 due to its simplicity, reliability and easy operation. This design not only reduces the structural complexity and maintenance requirements, but also improves the user experience when adjusting the antenna position, especially in application scenarios where the antenna position needs to be adjusted frequently.

[0049] In a specific implementation, the first magnetic attraction member 211 and the second magnetic attraction member 54 can both be magnets, or one can be a magnet and the other can be an iron block.

[0050] In other embodiments, a plurality of holes may be provided on the top of the first frame 21 , and a plug post that can be plugged into each hole may be provided on the support arm 51 , so that fixation can also be achieved.

[0051] The outer surface of each clamping member 53 is a convex arc surface;

[0052] The groove surface of each engaging groove 43 is a concave arc surface.

[0053] By optimizing the contact surface design between the snap-fit ​​part 53 and the snap-fit ​​groove 43, the smoothness of the connection is further improved. This design makes the sliding and locking actions smoother when adjusting the height or position of the slide 5, reduces the jamming or wear caused by the mismatch of the contact surface, and extends the service life of the equipment. The arc surface design can also disperse the pressure of the contact point to a certain extent, reduce local wear, and ensure stability and reliability in long-term use.

[0054] In addition, the contact characteristics of the arc surface make the contact between the clamping member 53 and the clamping groove 43 smoother, reducing the friction and vibration caused by direct contact, both of which are the main causes of noise. When the slide seat 5 is adjusted and moved in the height direction or length direction, the sliding contact characteristics of the arc surface can significantly reduce the noise generated by friction.

[0055] The second frame 22 is also provided with a guide rail 4 , and the bottom of the second antenna 32 is also provided with a slide seat 5 that slidably cooperates with the guide rail 4 on the second frame 22 .

[0056] The above description is only a preferred embodiment of the present invention, and does not limit the patent scope of the present invention. All equivalent structural changes made by using the contents of the present invention specification and drawings under the inventive concept of the present invention, or directly / indirectly applied in other related technical fields are included in the patent protection scope of the present invention.
