Description

Technical Field

[0001] This application relates to the field of GNSS antenna storage technology, and in particular to a GNSS antenna loading device and a portable storage container. Background Technology

[0002] GNSS high-precision measurement technology is a core technological support for key fields such as modern surveying and mapping engineering, deformation monitoring, precise positioning, and land spatial planning. Its positioning accuracy directly determines the reliability and authority of the data results. In this technological system, the GNSS antenna, as the core front-end component for receiving satellite signals, can effectively suppress multipath interference and provide a stable and unchanging phase center through its unique three-dimensional choke loop structure. This is the fundamental guarantee for achieving millimeter-level or even higher precision positioning.

[0003] However, as a high-precision electronic instrument, the internal radiating element and external choke ring structure of a GNSS antenna are extremely delicate, making it highly sensitive to shock, vibration, and pressure. During field operations, long-distance transportation, and frequent use, any improper bumps or continuous jolting can cause physical deformation, loosening of internal connections, or deviation in electrical performance, thereby affecting the accuracy of measurement results or even causing irreversible damage. Therefore, a professional mounting scheme must be designed to ensure adequate isolation, buffering, and stable structural support even in complex mobile environments.

[0004] Currently, during the field transport or long-distance transport of GNSS antennas, surveyors mainly use two temporary methods: First, they place the antenna in a general-purpose instrument backpack or suitcase with excessive internal space. Due to the lack of effective internal partitions and fixing structures, the GNSS antenna is in a free-floating state inside the bag, frequently shaking and sliding during transport and vehicle travel, and may even collide with other tools inside the bag. This can easily cause deformation or surface damage to its delicate choke structure, thus affecting its performance and measurement accuracy. Second, during vehicle transport, to avoid severe shaking caused by bumps, surveyors have to place the antenna inside the vehicle seat and carry it by hand. This not only occupies valuable manpower and seating space, but also poses risks due to the inability to effectively cushion vehicle vibrations, and greatly restricts other activities during the journey, seriously affecting work efficiency and personnel experience. In addition, when moving the antenna on foot in complex terrain (such as mountains and forests), the lack of a dedicated carrying system makes the transport work particularly difficult and dangerous.

[0005] In summary, existing loading methods cannot provide GNSS antennas with stable fixation, effective buffering, and convenient access, which is a huge contrast to the high-precision positioning of the instrument itself. There are currently no dedicated loading tools on the market specifically designed for this type of GNSS antenna, resulting in many hidden dangers and inconveniences in transportation and carrying.

Detailed Implementation

[0021] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. The components of the embodiments of the present invention described and labeled in the accompanying drawings can generally be arranged and designed in various different configurations.

[0022] Therefore, the following detailed description of the embodiments of the invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the invention without inventive effort are within the scope of protection of the invention.

[0023] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0024] In the description of this invention, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship commonly used when the product of this invention is in use. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this invention. In addition, the terms "first," "second," "third," etc., are only used to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0025] Furthermore, terms such as "horizontal," "vertical," and "sag" do not imply that components must be absolutely horizontal or suspended, but rather that they can be slightly tilted. For example, "horizontal" simply means that its direction is more horizontal relative to "vertical," and does not mean that the structure must be completely horizontal, but can be slightly tilted.

[0026] In the description of this invention, it should also be noted that, unless otherwise explicitly specified and limited, the terms "set," "install," "connect," and "link" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0027] The following detailed description of some embodiments of the present invention is provided in conjunction with the accompanying drawings. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0028] Early GNSS antenna products often adopted a design where the core component and the outer casing were detachable. The outer casing served only as a physical protective component and did not affect the antenna's operating performance. Surveyors, seeking portability, typically carried and used only the GNSS antenna core component, which was small and very easy to carry.

[0029] With technological advancements, new GNSS antennas have undergone fundamental design changes: their external protective covers are now crucial for correcting and stabilizing the antenna's phase center, and must form a complete working system together with the core components. Simultaneously, the newly issued high-precision GNSS measurement specifications explicitly require the use of complete, original equipment manufacturer (OEM) integrated antenna systems for observations to ensure the consistency of measurement data sources and the reliability of the final results. This signifies that industry standards are comprehensively promoting the transformation of measurement operations towards integrated antenna systems from a technical specification perspective.

[0030] Driven by technological advancements and industry standards, it is anticipated that more integrated GNSS antenna products of various models and sizes will emerge in the future. This diversification of GNSS antenna dimensions creates an urgent and widespread demand for versatile, adaptable dedicated mounting tools.

[0031] like Figures 1 to 6 As shown, this application provides a GNSS antenna loading device, characterized in that it includes a base 2, an axial limiting mechanism and a radial locking mechanism; since the GNSS antenna 1 is a hemisphere, the base 2 is preferably a disc, which meets the installation requirements while saving space.

[0032] An axial limiting mechanism is provided on the base 2, including a bottom suction cup 10 located at the center of the base 2. The bottom suction cup 10 is connected to the base 2 by a suction cup spring 11. The bottom suction cup 10 has a spherical tray that matches the shape of the outer cover of the GNSS antenna 1 to facilitate the positioning and support of the GNSS antenna 1.

[0033] Three linkage shafts 12 parallel to the base 2 are evenly spaced on the side of the bottom suction cup 10. Three slide rails corresponding to the linkage shafts 12 and extending radially along the base 2 are provided on the base 2. Three linkage sliders 14 are slidably installed on each slide rail. The two ends of the three connecting shafts 13 are respectively hinged to the corresponding linkage shafts 12 and linkage sliders 14.

[0034] The surface of the linkage slider 14 facing away from the base 2 is inclined, and a guide seat 15 corresponding to each linkage slider 14 is provided on the base 2. The guide seat 15 is inverted U-shaped and spans above the linkage slider. Three linkage rods 16 are slidably disposed on each guide seat 15. The first end of each linkage rod 16 is provided with a rotatably connected linkage wheel 17. The linkage rod 16 contacts the inclined surface of the corresponding linkage slider 14 through the rotating wheel 17. The second end of the linkage rod 16 is fixedly connected to the fixing ring 9. Six tension springs 18 are divided into three groups and are respectively disposed on both sides of the guide seat 15. One end of the tension spring 18 is connected to the fixing ring 9, and the other end is connected to the base 2 through the tension spring connecting post 19. The fixing ring 9 is preferably a circular ring to better fit the hemispherical GNSS antenna 1.

[0035] Three radial locking mechanisms are evenly arranged on the fixed ring 9 and are respectively set with three connecting rods 16. The corresponding linkage shaft 12, connecting shaft 13, linkage slider 14, connecting rod 16 and radial locking mechanism are arranged in the same plane to form a set of limiting locking mechanisms. The three sets of limiting locking mechanisms are distributed at 120° intervals in the circumferential direction.

[0036] The radial locking mechanism includes a slide rail box 3 with an opening facing the center of the fixing ring 9. A slide rail latch 6 is inserted into the slide rail box 3, and the rear end of the slide rail latch 6 is connected to the inner bottom surface of the slide rail box 3 by a slide rail spring 5. A latching wheel 8 is rotatably connected to the front end of the slide rail latch 6. The triangular area formed by the front ends of the three slide rail latches 6 can completely fall within the bottom surface of the GNSS antenna 1's outer casing. Therefore, after the GNSS antenna 1 is installed, the three slide rail latches 6 can pop out of the slide rail box 3 and lock onto the bottom surface of the GNSS antenna 1's outer casing. The latching wheel 8 can convert sliding friction into rolling friction, effectively reducing the installation resistance of the GNSS antenna 1 and preventing scratches on the surface of the GNSS antenna 1's outer casing.

[0037] A slide rail protrusion 4 is located near the center of the slide rail box 3. A pin spring 7, which engages with the slide rail latch 6, is mounted on the slide rail latch 6. In its natural state, the slide rail latch 6 extends out of the slide rail box 3 under the elastic force of the slide rail spring 5, and the pin spring 7 is in an extended state, protruding from the surface of the slide rail box 3, preventing the slide rail latch 6 from retracting, thus achieving a "midpoint self-locking" function. When the pin spring 7 is pressed down and the slide rail latch 6 is pressed into the slide rail box 3 to a certain position, the pin spring 7 pops out at the slide rail protrusion 4 and engages with it, locking the position of the slide rail latch 6. The slide rail protrusion 4 is made of a metal sheet with a certain elasticity or a flexible material. Pressing the slide rail protrusion 4 causes the pin spring 7 to retract, and the slide rail latch 6 pops out of the slide rail box 3 under the elastic force of the slide rail spring 5, achieving a "one-click pop-out" function.

[0038] The use of the pin spring 7 and the slide rail cover 4 in conjunction with each other enables the "midpoint self-locking" and "one-click pop-out" functions, greatly improving the convenience and reliability of GNSS antenna 1 in handling. The "midpoint self-locking" function effectively prevents the slide rail clip 6 from slipping open due to accidental bumps or vibrations in outdoor environments, thus eliminating the risk of the GNSS antenna 1 accidentally coming loose during transportation and ensuring absolutely reliable fixation. The "one-click pop-out" function allows the slide rail clip 6 to remain stably in the locked position, providing clear auditory and tactile feedback. Combined with a clear "click" sound and a springy feel, surveyors can easily remove the antenna with one hand, making operation convenient.

[0039] The fixing ring 9, bottom suction cup 10, suction cup spring 11, linkage shaft 12, connecting shaft 13, linkage slider 14, guide seat 15, linkage rod 16, linkage rod wheel 17 and tension spring 18 together form a "radial locking" of the GNSS antenna 1.

[0040] The linkage shaft 12, connecting shaft 13, and linkage slider 14 form a "three-point linkage displacement structure." This linkage mechanism cleverly converts the axial pressure on the bottom suction cup 10 when the GNSS antenna 1 is installed into the horizontal displacement of the linkage slider 14, thus providing a power source for subsequent radial locking. The horizontal movement of the linkage slider 14 further drives the connecting rod 16 to move vertically, ultimately accurately transmitting the radial movement of the linkage slider 14 to the axial movement of the fixed ring 9, achieving a secondary conversion of the motion direction. The connecting rod wheel 17 can achieve low-friction sliding, making the motion conversion smoother.

[0041] Six sets of tension springs 18 are evenly distributed around the fixing ring 9 by M3 screws. Through the synergistic effect of multiple elastic elements, the radial locking force applied to the GNSS antenna 1 is ensured to be highly uniform and symmetrical, avoiding the GNSS antenna 1 from tilting or stress concentration due to uneven force at a single point, thereby achieving all-round flexible clamping and reliable fixation of the GNSS antenna 1.

[0042] After the radial locking mechanism releases the radial lock on the GNSS antenna 1 and the GNSS antenna 1 is removed, the compressed suction cup spring 11 will reset the bottom suction cup 10, and at the same time the stretched tension spring 18 will pull the entire linkage mechanism back to its initial open state, ready for the next loading.

[0043] When placing the GNSS antenna 1, align it with the hemispherical groove of the bottom suction cup 10 of the loading device, and gently press it in along the axis of the groove. The outer surface of the GNSS antenna 1 first contacts the locking wheel 8, and the curved surface of the outer cover of the GNSS antenna 1 will generate uniform axial pressure on the slide rail latch 6, forcing the slide rail latch 6 to slide along the axis of the slide rail box 3. The slide rail spring 5 gradually changes from its natural state to a compressed state. With continued pressing, the curved surface of the outer cover of the GNSS antenna 1 contacts the bottom suction cup 10 and is attracted. The suction cup spring 11 is compressed, and the linkage shaft 12, connecting shaft 13, and linkage slider 14 move axially in conjunction, pushing the linkage rod 16 to move axially, and the tension spring 18 is stretched. Until the GNSS antenna 1 is completely in the loading device, the slide rail spring 5 returns to its natural state, the slide rail latch 6 returns to its original position and locks the bottom surface of the GNSS antenna 1.

[0044] When removing the GNSS antenna 1, push the slide rail latch 6 towards the outside of the antenna. When the slide rail latch 6 is pushed to a certain critical position, that is, after the axis of the pin spring 7 aligns with the slide rail convex cover 4, the slide rail latch 6 stabilizes in the unlocked position, thereby releasing the axial constraint on the GNSS antenna 1. At this time, the bottom suction cup 10 is reset by the suction cup spring 11, and the GNSS antenna 1 is smoothly and controllably pushed out of the hemispherical groove of the bottom suction cup 10 a certain distance, so that the bottom suction cup 10 is released from the tightly fitted state and enters the ready position that can be easily removed.

[0045] like Figures 7-8 As shown, this embodiment also provides a portable storage container, including a storage container body 20 and a storage container cover 21; the GNSS antenna mounting device can be fixedly installed in the storage container body 20, and the storage container cover 21 can be sealed to the storage container body 20.

[0046] The bottom of the storage container body 20 is provided with a shoulder strap 26, and the sides are provided with a power supply compartment 23 and a handle 24. The power supply compartment 23 is fixed to the side of the storage container body 20 and has a built-in power source (such as a power bank or a dedicated battery). It needs to conduct power through a cable to power external devices. The cable is routed through a dedicated cable hole at the bottom and sealed with an annular sealing ring for the cable hole.

[0047] The handle 24 houses a rain cover 22, one end of which is sewn to the inside of the storage compartment of the handle 24. When in use, it can be pulled out and unfolded from the storage compartment opening; when not in use, it can be folded back and tucked back into the storage compartment. The rain cover 22 has an elastic drawstring along its edge, which, when unfolded, can cover the lid 21 of the storage container and the connection between the lid 21 and the main body 20 of the storage container. Furthermore, each side of the rain cover 22 has a hidden hook, corresponding to the buckles 25 at various positions on the main body 20 of the storage container. When fastened, the rain cover 22 fits snugly against the outer surface of the lid 21 of the storage container, without any looseness or gaps, thus providing rain protection.

[0048] The technical effect of this embodiment is as follows: The loading device, through a dual adjustable mechanism of "axial limiting" and "radial locking," can tightly fit and fix GNSS antennas of different diameters and heights with simple adjustments. This allows the loading device to be compatible with a variety of mainstream and future GNSS antenna models on the market, greatly improving the product's versatility and usability. At the same time, it fundamentally eliminates shaking, collisions, and vibrations during the transportation of GNSS antennas, providing a high level of customized protection for core precision components.

[0049] This portable storage container is designed for the complex and ever-changing environments of field surveying. While ensuring the safety of the GNSS antenna, it features a well-planned storage space, an integrated rain cover, and built-in convenient charging for commonly used tools such as walkie-talkies and handheld devices. It achieves "one-pack storage, ready to use," with the rain cover providing all-weather operation capabilities and ensuring the safety of instruments and accessories in sudden rain or snow. The built-in charging solution ensures a continuous power supply for electronic components, effectively solving the pain point of inconvenient power replenishment in the field, extending effective working time, and improving team collaboration efficiency.
