Technical Field

[0001] This application relates to the field of measurement communication electronic equipment technology, specifically to an antenna structure and a mobile measurement device. Background Technology

[0002] In the technology related to mobile measurement equipment, the external radio frequency antennas of outdoor mobile measurement equipment such as RTK devices often take the form of rubber rod antennas or long fiberglass antennas. Among them, rubber rod antennas are small in size and easy to carry and install, but their transmission performance is limited; while fiberglass antennas have better transmission performance, but due to their excessive length and weight, they are not convenient for outdoor carrying and installation to meet the ergonomic requirements of products. Therefore, there is currently a need for an antenna structure that is easy to carry and has good transmission performance to meet user needs. Utility Model Content

Therefore, they should not be construed as limitations on this application. Furthermore, the terms "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0022] It should also be noted that, unless otherwise explicitly specified and limited, the terms "setup" and "connection" 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 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 application based on the specific circumstances.

[0023] Please refer to Figure 1 , Figure 2 As shown, this application provides an antenna structure, including: an antenna housing 20 sleeved outside the device housing 10, the device housing 10 is used to house the device body, the device housing 10 and the antenna housing 20 are interlocked along a first direction F1, and at least one omnidirectional antenna 22 is disposed on the antenna housing 20.

[0024] At least one omnidirectional antenna 22 is provided on the inner wall of the antenna housing 20. The omnidirectional antenna 22 is built into the antenna housing 20. The antenna housing 20 is also fitted outside the device housing 10, so that the device housing 10 and the antenna housing 20 form an integrated structure. This makes the overall structure compact, neat in appearance, and has the advantages of simple ergonomics, making it easy to carry and adapting to the needs of miniaturization. At the same time, its omnidirectional antenna 22 structure can transmit signals in all directions of 360 degrees, which greatly increases the transmission performance of the antenna and can meet the needs of customers with good transmission performance and portability.

[0025] For example, both the antenna housing 20 and the device housing 10 are cylindrical housings. The antenna housing 20 is a cylindrical structure with openings at both ends and a hollow interior, to facilitate the fitting of the device housing 10. The device housing 10 is a cylindrical structure with an opening at one end. There are multiple omnidirectional antennas 22, which are evenly distributed around the inner wall of the antenna housing 20.

[0026] The antenna housing 20 is inserted into the device housing 10. The antenna housing 20 is provided with a first limiting groove 25 along the radial direction F2 (circumferential direction). The device housing 10 is provided with a corresponding limiting rib 12. The limiting rib 12 is inserted into the first limiting groove 25 to limit the antenna housing 20 and the device housing 10 in the radial direction F2. The radial direction F2 is perpendicular to the first direction F1.

[0027] When the antenna housing 20 is inserted into the device housing 10, the limiting rib 12 of the device housing 10 is inserted into the first limiting groove 25 of the antenna housing 20, and the two are inserted into each other along the first direction F1 to form a whole, which can also form a radial limit on the antenna housing 20 and the device housing 10.

[0028] There are multiple first limiting grooves 25 and multiple limiting ribs 12. The multiple first limiting grooves 25 are evenly distributed around the first end face 202 of the antenna housing 20, and the multiple limiting ribs 12 are evenly distributed around the second end face 101 of the device housing 10.

[0029] The arrangement of multiple first limiting slots 25 and multiple limiting ribs 12 ensures that the first limiting slots 25 and limiting ribs 12 are arranged at different positions along the circumference of the outer shell antenna and the device antenna for insertion, making the insertion of the outer shell antenna and the device antenna more stable.

[0030] The equipment housing 10 is provided with a second end face 101 of a limiting rib 12 forming a flange 101a, and the limiting rib 12 is located on the flange 101a.

[0031] like Figure 1As shown, the second end face 101 at the bottom of the equipment housing 10 forms an outward flange 101a, and a plurality of limiting ribs 12 are circumferentially distributed in a circle on the flange 101a. Furthermore, the flange 101a can also serve as a reinforcing rib to strengthen the structure of the equipment housing 10.

[0032] In addition, a second limiting groove 24 is provided on the antenna housing 20 along the first direction F1, and a corresponding limiting protrusion 14 is provided on the device housing 10. The limiting protrusion 14 is engaged with the second limiting groove 24, thereby further realizing the insertion of the antenna housing 20 and the device housing 10 along the first direction F1.

[0033] For example, there are multiple second limiting slots 24, which are distributed circumferentially; correspondingly, there are also multiple limiting protrusions 14 on the device housing 10, which are also distributed circumferentially to correspond one-to-one with the second limiting slots 24. The circumferential distribution of the multiple second limiting slots 24 and the multiple limiting protrusions 14 further limits the antenna housing 20 and the device housing 10 in the radial direction F2.

[0034] As mentioned above, the antenna housing 20 has a first end face 202 with a first limiting groove 25, and correspondingly, the other end of the first end face 202 along the first direction F1 is the third end face 201 of the antenna housing 20; the device housing 10 has a second end face 101 with a limiting rib 12, and the other end of the second end face along the first direction F1 is the fourth end face 102 of the device housing 10. The first end face 202 of the antenna housing 20 and the second end face 101 of the device housing 10 are fixed at their ends, and the third end face 201 of the antenna housing 20 and the fourth end face 102 of the device housing 10 are fixedly connected at their ends.

[0035] Specifically, a first mounting hole 26 is provided on the first end face 202 of the antenna housing 20, and a second mounting hole 13 is provided on the second end face 101 of the device housing 10. The first mounting hole 26 and the second mounting hole 13 are connected by a first fastener 15 so that the antenna housing 20 and the device housing 10 are fixed at the end face.

[0036] The first mounting hole 26 is a screw hole, the second mounting hole 13 is a through hole, and the first fastener 15 is a screw. After the first fastener 15 passes through the second mounting hole 13, it is locked in the first mounting hole 26, thus fixing the end face of the antenna housing 20 to the equipment housing 10.

[0037] On the other hand, a third mounting hole 21 is provided on the third end face 201 of the antenna housing 20, and a fourth mounting hole 11 is provided on the fourth end face 102 of the device housing 10. The third mounting hole and the fourth mounting hole are connected by a second fastener 23 so that the antenna housing 20 and the device housing 10 are fixed on the other end face.

[0038] For example, the third mounting hole 21 can be a countersunk hole, the fourth mounting hole 11 is a screw hole, and the second fastener 23 is a screw; the second fastener 23 passes through the third mounting hole 21 and is locked in the fourth mounting hole 11, forming a fixed connection between the antenna housing 20 and the other end face of the device housing 10.

[0039] In summary, by uniformly embedding the omnidirectional antenna 22 within the antenna housing 20 in a circular pattern, and then fixing it to the equipment housing 10 through structural features to form an integrated structure and appearance, the directional limitations of the antenna transmission performance of existing external antenna structures in measurement equipment are improved, allowing the antenna to transmit in 360 degrees. This also significantly reduces the cumbersome installation and carrying associated with external antenna structures, while simultaneously improving the overall aesthetics of the equipment. The structure after the antenna housing 20 and the equipment housing 10 are fitted together is as follows: Figure 3 As shown.

[0040] Based on this, the present application also discloses a mobile measuring device, including a device housing 10, a device body disposed within the device housing 10, and an antenna structure as described above disposed outside the device housing 10.

[0041] This mobile measuring device incorporates the same structure and beneficial effects as the antenna structure in the foregoing embodiments. The structure and beneficial effects of the antenna structure have been described in detail in the foregoing embodiments and will not be repeated here.

[0042] The above description is merely an embodiment of this application and is not intended to limit the scope of protection of this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the scope of protection of this application.
