Description

Technical Field

[0001] This application belongs to the field of communication equipment technology, specifically relating to a quick-release installation module and an RTK antenna device. Background Technology

[0002] RTK (Real-Time Kinematic) antennas are key components in high-precision satellite positioning systems, primarily used to receive and amplify satellite navigation signals. Their performance directly impacts positioning accuracy and system stability. With the rapid development of precision agriculture, UAV mapping, and autonomous driving, RTK technology has gained widespread application due to its centimeter-level positioning accuracy. As the signal acquisition front-end of an RTK receiver, the antenna must maintain stable and reliable physical connections and signal transmission quality under complex operating conditions, which places stringent requirements on the antenna's mechanical fixing methods and environmental adaptability.

[0003] Currently, there are two main types of technical solutions for fixing RTK antennas on the market: The first type uses a plug-in snap-fit ​​structure, which is convenient to install but is prone to accidental removal. In addition, when the equipment is moved or vibrates, the antenna is easily subjected to radial force, which can cause mechanical shaking, resulting in decreased signal transmission stability or even poor contact. The second type uses a threaded screw-in fixing method, which can improve axial tightening force, but disassembly and assembly are relatively complicated, and frequent disassembly and assembly can easily cause thread wear and failure, resulting in problems such as short mechanical life of the connectors and high maintenance costs. Utility Model Content

[0004] The purpose of this application is to provide a quick-release installation module and RTK antenna device to solve the problems of existing RTK antenna fixing structures that use plug-in connections which are prone to accidental removal and loosening during use, affecting normal use; and threaded connections which are relatively complex to install and disassemble, and whose threads are prone to wear and failure, resulting in short service life and high maintenance costs.

[0005] To achieve the above objectives, the first aspect of this application provides a quick-release mounting module for use in an RTK antenna device, the quick-release mounting module comprising:

[0006] Connect the top cover to the RTK antenna body for mounting the RTK antenna device; and

[0007] A fixed base is rotatably engaged with the connecting cover. The outer edge of the fixed base facing the connecting cover has at least two engagement notches. The outer circumference of the fixed base has a screw guide groove corresponding to each engagement notch. One end of the screw guide groove communicates with the engagement notch, and the other end extends along the screwing engagement direction of the connecting cover. The fixed base also has a foolproof notch on the side facing the connecting cover. Below the foolproof notch is a receiving groove, and the extending direction of the receiving groove is consistent with that of the screw guide groove.

[0008] The connecting cover has a hook for each snap-fit ​​notch and a rib for each snap-fit ​​notch. When the rib is aligned with the snap-fit ​​notch, each hook is aligned with the corresponding snap-fit ​​notch.

[0009] As a further improvement to the above technical solution:

[0010] In some embodiments, the quick-release mounting module further includes an elastic preload assembly;

[0011] The fixed base is provided with the elastic pre-tightening component on the side facing the connecting cover. The elastic pre-tightening component is used to elastically abut against the connecting cover. The connecting cover is provided with a positioning groove for the elastic pre-tightening component to extend into and be positioned.

[0012] Alternatively, the connecting cover may have the elastic pre-tightening component on the side facing the fixed base, the elastic pre-tightening component being used to elastically abut against the fixed base, and the fixed base having a positioning groove for the elastic pre-tightening component to extend into and be positioned.

[0013] In some embodiments, the elastic preload assembly includes a mounting cylinder, preload balls, and an elastic element;

[0014] The mounting cylinder is provided with a receiving hole;

[0015] The pre-tightening ball is disposed at the opening of the receiving hole of the mounting cylinder and can rotate relative to the mounting cylinder. The diameter of the pre-tightening ball is larger than the diameter of the opening of the mounting cylinder.

[0016] The elastic element is arranged in the receiving hole, with one end abutting the bottom of the receiving hole and the other end abutting the preload ball. The elastic element provides elastic thrust to the preload ball so that the preload ball is at least partially exposed outside the opening of the receiving hole.

[0017] In some embodiments, the quick-release mounting module further includes a first seal, which is disposed between the connecting cover and the fixed base, with the connecting cover and the fixed base respectively abutting against opposite sides of the first seal.

[0018] In some embodiments, the connecting cover has a sealing mounting groove for installing the first sealing element on the side facing the fixed base; or, the fixed base has a sealing mounting groove for installing the first sealing element on the side facing the connecting cover.

[0019] The second aspect of this application provides an RTK antenna device, including an RTK antenna body, a host, an RTK adapter, and a quick-release mounting module according to the first aspect above.

[0020] The RTK antenna body is mounted on the connecting cover and located on the side of the connecting cover away from the fixed base;

[0021] The fixed base is mounted on the host computer;

[0022] One end of the RTK adapter passes through the connecting cover and is electrically connected to the RTK antenna body, while the other end passes through the fixing base and is plugged into the host, for establishing a communication connection between the RTK antenna body and the host.

[0023] As a further improvement to the above technical solution:

[0024] In some embodiments, the RTK antenna body and the connecting cover are detachably connected;

[0025] A second sealing element is provided between the RTK antenna body and the connecting cover.

[0026] In some embodiments, the mounting base is detachably connected to the main unit;

[0027] A third sealing element is also provided between the fixed base and the main unit.

[0028] In some embodiments, the connecting cover is provided with a sensing element, and the host is provided with a sensing detection module;

[0029] When the connecting cover and the fixed base are engaged, the sensing module and the sensing element form a sensing engagement, wherein the sensing module is used to feed the sensing signal back to the controller of the host.

[0030] In some embodiments, the host computer is provided with an RTK socket that is plugged into the RTK adapter, and the mounting base is provided with a clearance through hole for the RTK adapter to pass through, the clearance through hole being aligned with the plug hole of the RTK socket.

[0031] Compared to existing technologies, the quick-release mounting module and RTK antenna device provided in this application have at least the following advantages:

[0032] The quick-release installation module provided in this application features a foolproof notch and at least two snap-fit ​​notches on the fixed base, with each snap-fit ​​notch corresponding to a screw guide groove. The connecting cover has hooks corresponding to each snap-fit ​​notch and foolproof ribs corresponding to the foolproof notches. To connect the connecting cover to the fixed base, first align the connecting cover with the fixed base, then align the foolproof ribs with the foolproof notches on the fixed base. When the foolproof ribs and notches are aligned, each hook naturally aligns with its corresponding snap-fit ​​notch. Then, bring the connecting cover and fixed base closer together, allowing the foolproof ribs to insert into the foolproof notches and into the receiving grooves, and the hooks to insert into their corresponding snap-fit ​​notches and into the screw guide grooves. Rotate the connecting cover along the extension direction of the screw guide grooves to achieve a rotating snap-fit ​​engagement between the connecting cover and the fixed base. To disassemble, simply screw the connecting cover in the opposite direction, causing the hooks on the connecting cover to retract and align with the snap-fit ​​notches, then pull out the connecting cover to complete the disassembly.

[0033] The quick-release installation module provided in this application uses a rotating snap-fit ​​connection between the top cover and the fixed base, resulting in a more stable connection. Because it is a screw-fit connection, it cannot be accidentally pulled out and is less prone to loosening during use. Furthermore, the absence of a threaded connection makes installation and disassembly faster, simplifies the structure, extends service life, and reduces maintenance costs.

[0050] The specific embodiments of this application will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit this application.

[0051] The present application will now be described in detail with reference to the accompanying drawings and exemplary embodiments.

[0052] Example 1

[0053] Please see Figure 1 , Figure 2 and Figure 3 This embodiment provides a quick-release installation module 100, which is applied to an RTK antenna device and can realize the quick installation and removal of the RTK antenna body 200 of the RTK antenna device.

[0054] The quick-release mounting module 100 provided in this embodiment includes a connecting cover 110 and a fixing base 120. The connecting cover 110 is used to mount the RTK antenna body 200 of the RTK antenna device; the fixing base 120 is used to connect to the host 300 of the RTK antenna device.

[0055] Please refer to the following: Figure 4 The fixed base 120 is rotatably engaged with the connecting cover 110. The outer edge of the fixed base 120 facing the connecting cover 110 has at least two engagement notches 121. Corresponding to each engagement notch 121, the outer periphery of the fixed base 120 has a screw guide groove 122. One end of the screw guide groove 122 communicates with the engagement notch 121, and the other end extends along the screwing direction of the connecting cover 110. This embodiment illustrates three engagement notches 121, corresponding to three screw guide grooves 122. It is understood that the number of engagement notches 121 can also be four, five, or other numbers. This embodiment is merely illustrative and is not intended to limit the scope of protection of this application.

[0056] Furthermore, the fixed base 120 is provided with a foolproof notch 123 on the side facing the connecting cover 110, and a receiving slot 124 is provided below the foolproof notch 123. The receiving slot 124 extends in the same direction as the screw guide slot 122.

[0057] The upper cover 110 is provided with a hook 113 corresponding to each snap-fit ​​notch 121 and a foolproof rib 111 corresponding to the foolproof notch 123. When the foolproof rib 111 is aligned with the foolproof notch 123, each hook 113 is aligned with the corresponding snap-fit ​​notch 121.

[0058] Please refer to the following: Figure 6 and Figure 7 It is understood that, when the quick-release installation module 100 provided in this embodiment connects the upper cover 110 and the fixed base 120, it first aligns the upper cover 110 and the fixed base 120, and then aligns the anti-foolproof protrusion 111 with the anti-foolproof notch 123 on the fixed base 120. When the anti-foolproof protrusion 111 and the anti-foolproof notch 123 are aligned, each hook 113 is naturally aligned with the corresponding snap-fit ​​notch 121. At this time, the upper cover 110 and the fixed base 120 are brought closer together (e.g., ...). Figure 6 As shown, a thrust F is applied, causing the anti-foolproof rib 111 to insert into the anti-foolproof notch 123 and enter the receiving slot 124. Simultaneously, the hook 113 is inserted into the corresponding engagement notch 121 and enters the screw-guide slot 122. Then, the upper cover 110 is rotated along the extension direction of the screw-guide slot 122, thereby achieving a rotational engagement between the upper cover 110 and the fixed base 120 (e.g., Figure 7(The direction indicated by the middle arrow V is the direction of screwing and locking.) When disassembly is required, simply screw the connecting cover 110 in the opposite direction so that the hook 113 on the connecting cover 110 retracts and aligns with the locking notch 121. Then pull out the connecting cover 110 to achieve disassembly.

[0059] Thus, the quick-release installation module 100 provided in this embodiment uses a rotating snap-fit ​​connection between the upper cover 110 and the fixed base 120, resulting in a more stable connection. Because it is a screw-fit connection, it cannot be accidentally pulled out, and it is not easy to loosen during use. Furthermore, the absence of a threaded structure for connection makes installation and disassembly faster, the structure is simpler, the service life is extended, and maintenance costs are reduced.

[0060] Please see Figure 2 , Figure 6 and Figure 7 Furthermore, the quick-release installation module 100 also includes an elastic pre-tightening component 130. The fixed base 120 is provided with the elastic pre-tightening component 130 on the side facing the connecting cover 110. The elastic pre-tightening component 130 is used to elastically abut against the connecting cover 110. The connecting cover 110 is provided with a positioning groove 114 for the elastic pre-tightening component 130 to extend into and be positioned.

[0061] Alternatively, in some embodiments, the side of the connecting cover 110 facing the fixed base 120 is provided with an elastic pre-tightening component 130, which is used to elastically abut against the fixed base 120. The fixed base 120 is provided with a positioning groove 114 for the elastic pre-tightening component 130 to extend into and be positioned.

[0062] Specifically, this embodiment uses the example of an elastic pre-tightening assembly 130 mounted on a fixed base 120 for illustration. The elastic pre-tightening assembly 130 includes a mounting cylinder, a pre-tightening ball, and an elastic element. The mounting cylinder is mounted on the fixed base 120 and has a receiving hole inside. The pre-tightening ball is positioned at the opening of the receiving hole in the mounting cylinder and can rotate relative to the mounting cylinder; the diameter of the pre-tightening ball is larger than the diameter of the opening in the mounting cylinder. The elastic element is arranged in the receiving hole, with one end abutting the bottom of the receiving hole and the other end abutting the pre-tightening ball. The elastic element provides elastic thrust to the pre-tightening ball so that at least part of the pre-tightening ball is exposed outside the opening of the receiving hole. That is, under the thrust of the elastic element, the pre-tightening ball abuts against the opening of the receiving hole, at which point a portion of the spherical surface of the pre-tightening ball is located outside the opening.

[0063] Optionally, the elastic element is a compression spring or a sheet spring.

[0064] Please refer to the following: Figure 6 and Figure 7Understandably, when there is no rotational engagement between the connecting cover 110 and the fixed base 120, the elastic element drives the pre-tightening ball to remain at the opening of the receiving hole through elastic force. At this time, the ball of the pre-tightening ball is at least partially exposed outside the opening of the receiving hole. When a rotational engagement is formed between the connecting cover 110 and the fixed base 120, the pre-tightening ball located at the opening of the receiving hole is squeezed and moves into the receiving hole, while compressing the elastic element to reduce the rotational friction between the connecting cover 110 and the fixed base 120. After the connecting cover 110 and the fixed base 120 are installed in place, the elastic element drives the pre-tightening ball to abut against the connecting cover 110, thereby generating a thrust based on the connecting cover 110. This thrust is the pre-tightening force between the connecting cover 110 and the fixed base 120, further ensuring that the connecting cover 110 and the fixed base 120 are more stable after assembly and preventing loosening.

[0065] Furthermore, the connecting cover 110 is provided with a positioning groove 114 on the side facing the fixed base 120 for the pre-tightening ball to extend into. Thus, when the connecting cover 110 is screwed into place, the pre-tightening ball will be engaged in the corresponding positioning groove 114, thereby restricting the circumferential rotation of the connecting cover 110. Only when the external force of screwing the connecting cover 110 in the opposite direction is greater than a certain value can the pre-tightening ball be forced out of the positioning groove 114, further preventing accidental disassembly and ensuring the stability after installation.

[0066] Alternatively, the elastic preload assembly 130 can also be made of glass beads.

[0067] Please see Figure 3 , Figure 5 and Figure 7 Furthermore, in this embodiment, the quick-release installation module 100 also includes a first sealing element 140, which is disposed between the connecting cover 110 and the fixed base 120. The connecting cover 110 and the fixed base 120 respectively abut against opposite sides of the first sealing element 140. Thus, the first sealing element 140 achieves sealing and waterproofing between the connecting cover 110 and the fixed base 120 after installation.

[0068] Optionally, the first sealing element 140 is a sealing ring, which can be a flat washer, an O-ring, a T-ring, etc.

[0069] Optionally, the first seal 140 is a rubber ring made of rubber material. Considering that the RTK antenna body 200 will be repeatedly disassembled, using rubber material can extend its service life.

[0070] In this embodiment, the side of the connecting cover 110 facing the fixed base 120 is provided with a sealing mounting groove for installing the first sealing member 140, and the first sealing member 140 is snapped into the sealing mounting groove.

[0071] In some embodiments, the fixed base 120 is provided with a sealing mounting groove for installing the first sealing member 140 on the side facing the connecting cover 110. In this way, the first sealing member 140 can be snapped into the sealing mounting groove on the fixed base 120, which can also achieve the sealing and waterproofing effect.

[0072] Example 2

[0073] Please see Figure 1 , Figure 2 , Figure 3 and Figure 5 This embodiment provides an RTK antenna device. The RTK antenna device includes an RTK antenna body 200, a host 300, an RTK adapter 400, and the quick-release mounting module 100 provided in Embodiment 1 above.

[0074] The RTK antenna body 200 is mounted on the connecting cover 110 and located on the side of the connecting cover 110 away from the fixed base 120; the fixed base 120 is mounted on the host 300; one end of the RTK adapter 400 passes through the connecting cover 110 and is electrically connected to the RTK antenna body 200, and the other end passes through the fixed base 120 and is plugged into the host 300, which is used to establish a communication connection between the RTK antenna body 200 and the host 300.

[0075] Please refer to the following: Figure 6 and Figure 7 Furthermore, the RTK antenna body 200 and the connecting cover 110 are detachably connected, for example, by means of snap-fit, threaded connection, or screw connection 150. A second sealing element 500 is provided between the RTK antenna body 200 and the connecting cover 110. Thus, the compression of the second sealing element 500 by the RTK antenna body 200 and the connecting cover 110 creates a waterproof seal between them.

[0076] Optionally, the second seal 500 can be directly installed on the side of the connecting cover 110 near the RTK antenna body 200, or it can be directly installed on the RTK antenna body 200.

[0077] Please refer to the following: Figure 6 and Figure 7 In some embodiments, the fixed base 120 and the main unit 300 are detachably connected, and can also be connected by snap-fit, threaded connection or screw 150 connection.

[0078] Furthermore, a third sealing element 600 is provided between the fixed base 120 and the main unit 300. In this way, a sealing fit is formed by the compression of the third sealing element 600 between the fixed base 120 and the main unit 300, thereby achieving a waterproof seal.

[0079] Optionally, the third seal 600 can be made of waterproof foam.

[0080] Please see Figure 3 and Figure 5 In some embodiments, a sensing element 112 is provided on the connecting cover 110, and a sensing detection module is provided inside the host 300. When the connecting cover 110 and the fixed base 120 are connected by a snap-fit, the sensing detection module and the sensing element 112 form a sensing engagement. The sensing detection module is used to feed back the sensing signal to the controller of the host 300, so that the controller can determine that the RTK antenna body 200 is installed in place, or further prompt by displaying "RTK" on the display on the host 300.

[0081] Optionally, the sensing element 112 is a magnetic element, and the sensing detection module can be a Hall effect detection module.

[0082] Please see Figure 2 , Figure 5 , Figure 6 and Figure 7 Furthermore, the main unit 300 is provided with an RTK socket 310 that mates with the RTK adapter 400, and the fixed base 120 is provided with a clearance through hole 125 for the RTK adapter 400 to pass through, the clearance through hole 125 being aligned with the insertion hole of the RTK socket 310. A first sealing member 140 is provided on the outer peripheral surface of the clearance through hole 125, thereby preventing water from entering the clearance through hole 125.

[0083] Therefore, the RTK antenna device provided in this embodiment achieves waterproof installation of the entire device through the first sealing element 140, the second sealing element 500, and the third sealing element 600. It provides excellent waterproofing and effectively prevents water from entering the antenna body or the entire device, thus preventing RTK failure. Therefore, the RTK antenna device provided in this embodiment can meet the needs of some complex outdoor working conditions.
