[0038] Antennas currently installed on self-mobile devices are usually disposed inside the fuselage, resulting in the need to completely remove the shell of the self-mobile device to disassemble the antenna when repairing the antenna, making the disassembly and assembly of the antenna inconvenient. At the same time, the built-in antenna will also result in relatively weak communication signals received and transmitted by the antenna, which is not conducive to the terminal device's control of the self-mobile device.

[0039] Based on this, in the first aspect, the present utility model proposes a self-mobile device with an external antenna, referring to Figures 1 to 7, the self - moving device with an external antenna includes: an antenna assembly 10, a housing 20, and a fixing base 30. A clamping plate 21 is provided on the housing 20; the fixing base 30 includes a mounting plate 31 and a hook 311 provided on the mounting plate 31. The mounting plate 31 is provided with a first mounting hole 312 for mounting the antenna assembly 10; when the fixing base 30 is mounted on the housing 20, the hook 311 is clamped on the clamping plate 21 to prevent the mounting plate 31 from deviating from the housing 20 when the antenna assembly 10 is disassembled and assembled.

[0040] Specifically, the antenna device is mounted on the housing 20 of the self - moving device. In this embodiment, a fixing base 30 is designed, and at the same time, the structural design of the housing 20 of the self - moving device is improved to adapt to the fixing base 30. The antenna assembly 10 is externally fixed on the housing 20 through the fixing base 30. A clamping plate 21 is provided on the housing 20. The clamping plate 21 can be integrally provided with the original housing 20 or fixed on the housing 20 through a fixing means such as screws. At the same time, the fixing base 30 includes a mounting plate 31 for mounting the antenna assembly 10. The mounting plate 31 is provided with a hook 311, and the hook 311 is clamped on the clamping plate 21 on the housing 20. On the one hand, when the fixing base 30 is fixed on the housing 20, installation alignment can be carried out, which is beneficial to the next - step installation of the fixing base 30. On the other hand, when the antenna needs to be disassembled, the fixing base 30 can also be firmly attached to the housing 20 to prevent a large gap from being generated between the fixing base 30 and the housing 20. A first mounting hole 312 is provided on the mounting plate 31, and the first mounting hole 312 is used for mounting the antenna assembly 10, that is, the antenna assembly 10 is connected to other components inside the housing 20 through the first mounting hole 312. Thus, in this embodiment, the antenna can be arranged outside the self - moving device, which is convenient for disassembly, assembly and maintenance of the antenna, and the signal receiving and transmitting intensity of the antenna is enhanced.

[0041] It should be noted that the above - mentioned antenna can be one of other antennas with communication functions such as a WiFi antenna, a Lora antenna, and a Halow antenna.

[0042] In some embodiments, the clamping plate 21 includes a first clamping portion 211 and a second clamping portion 212, and there is an opening 22 between the first clamping portion 211 and the second clamping portion 212; the hook 311 includes a first hook portion 3111 and a second hook portion 3112; when the fixing base 30 is mounted on the housing 20, the first hook portion 3111 is clamped on the first clamping portion 211, the second hook portion 3112 is clamped on the second clamping portion 212, and the first mounting hole 312 is located within the opening 22.

[0043] Specifically, the pallet 21 has a "U"-shaped opening 22, and two clamping parts are arranged on the pallet 21, namely a first clamping part 211 and a second clamping part 212. The opening 22 between the two clamping parts is used to accommodate the first mounting hole 312 on the fixing seat 30, so that the antenna assembly 10 can be connected to the devices inside the housing 20 through this opening 22. At the same time, hooks 311 are respectively arranged on both sides of the first mounting hole 312, and the first clamping part 211 and the second clamping part 212 are correspondingly arranged on the pallet 21, so that the fixing seat 30 can be more firmly clamped on the housing 20, and the force on both sides is uniform.

[0044] In some embodiments, the antenna assembly 10 includes a sleeve rod assembly 11 and a patch cord 12, and the sleeve rod assembly 11 and the patch cord 12 are detachably connected at the first mounting hole 312.

[0045] Specifically, the sleeve rod assembly 11 is arranged outside the housing 20, and the patch cord 12 is arranged inside the housing 20. The patch cord 12 is used to connect the external antenna assembly 10 and the receiving device inside the housing 20, and plays the roles of signal transmission, matching and enhancement. The patch cord 12 is used to transmit the wireless signal received by the antenna to the receiving device, so that the receiving device can decode and process the above signal. Moreover, the patch cord 12 can convert the output signal of the antenna into the connection interface required by the receiving device to ensure the smooth transmission of the signal. In addition, the patch cord 12 can also improve the signal quality during the signal transmission process, reduce signal attenuation and interference, thereby improving the performance of the receiving device. An antenna body is arranged in the sleeve rod assembly 11. After the sleeve rod assembly 11 is connected to the patch cord 12, the patch cord 12 can be connected to the antenna body, so that the antenna can be communicatively connected to the receiving device inside the housing 20. The sleeve rod assembly 11 is connected to the patch cord 12 inside the housing 20 through the first mounting hole 312, and the two are detachably connected, so as to facilitate the disassembly and maintenance of the antenna assembly 10.

[0046] In some embodiments, the patch cord 12 includes a connector 121 and a transmission line 122 perpendicular to the connector 121, and the sleeve rod assembly 11 is threadedly connected to the connector 121.

[0047] Specifically, the connector 121 in this embodiment has a threaded interface, and the threaded interface is threadedly connected to the sleeve rod assembly 11. The threaded interface can facilitate the fixing and locking and connection of the sleeve rod assembly 11. One end of the transmission line 122 is connected to the connector 121, and the other end of the transmission line 122 is connected to the antenna signal receiving device inside the housing 20. The connector 121 and the transmission line 122 are arranged perpendicular to each other, that is to say, the routing direction of the transmission line 122 is perpendicular to the interface direction of the threaded interface, so as to facilitate the layout of the transmission line 122 inside the housing 20 and will not affect the arrangement of other components inside the housing 20.

[0048] In some embodiments, the sleeve rod assembly 11 includes an antenna sleeve rod 111, a first connecting member 112 rotatably connected to the antenna sleeve rod 111, and a second connecting member 113 rotatably connected to the first connecting member 112. The second connecting member 113 is threadedly connected to the adapter 121.

[0049] Specifically, the antenna sleeve rod 111 is used to accommodate the antenna body. The antenna sleeve rod 111 is rotatably connected to the first connecting member 112. The rotational connection structure between the antenna sleeve rod 111 and the first connecting member 112 can adopt a fixed rotating shaft with one degree of freedom or a spherical rotating shaft with multiple degrees of freedom, and the angle of the antenna sleeve rod 111 can be fixed by means of frictional locking. The second connecting member 113 has an antenna interface for connecting to the patch cord 12, and the antenna interface has a thread. In this way, by threadedly connecting the antenna interface on the second connecting member 113 with the threaded interface of the patch cord 12, the patch cord 12 can be connected to the antenna. The antenna sleeve rod 111 is rotatably connected to the first connecting member 112 and the first connecting member 112 is also rotatably connected to the second connecting member 113, which enables the antenna sleeve rod 111 to rotate freely in multiple directions. The user can adjust the direction of the antenna as needed so that the antenna can receive or transmit stronger signals.

[0050] In some embodiments, on the inner side surface of the mounting plate 31, a positioning convex portion 313 is provided around the first mounting hole 312, and the positioning convex portion 313 is used to limit the position of the adapter 121.

[0051] Specifically, the inner side surface of the mounting plate 31 refers to the side of the mounting plate 31 facing the inside of the housing 20. To adapt to the length of the threaded interface of the adapter 121, a raised portion, that is, a positioning convex portion 313, is provided around the first mounting hole 312 on the inner side surface of the mounting plate 31. The positioning convex portion 313 can be an annular positioning convex portion surrounding the first mounting hole 312, or several square protrusions spaced around the first mounting hole 312. The number of the positioning convex portions 313 can be one or more. Multiple positioning convex portions 313 can be symmetrically arranged, so as to stably limit the position of the adapter 121 in the mounting direction. The mounting direction refers to the orientation of the threaded interface of the adapter 121 in the mounted state.

[0052] In some embodiments, a U-shaped limiting rib 314 is further provided on the inner side surface of the mounting plate 31 around the positioning convex portion 313. The opening of the U-shaped limiting rib 314 accommodates the adapter 121 to limit the position of the adapter 121.

[0053] Specifically, the U-shaped limiting rib 314 is a U-shaped protrusion arranged around the positioning protrusion 313. The U-shaped limiting rib 314 is provided on the inner side surface of the mounting plate 31. Its opening is used to accommodate the adapter 121. The shape of the opening is adapted to the outer shape of the adapter 121 of the patch cord 12. At the same time, the positioning protrusion is located within the opening of the U-shaped limiting rib 314. When connecting the patch cord 12 to the sleeve rod assembly 11, the threaded interface of the adapter 121 is oriented towards the first mounting hole 312, and then the adapter is snapped into the opening of the U-shaped limiting rib 314, so that the position of the adapter 121 in the direction parallel to the inner side surface can be fixed. The positioning protrusion restricts the position of the adapter 121 in the installation direction. Through the combined structure of the U-shaped limiting rib 314 and the positioning protrusion, the installation alignment of the adapter 121 can be accurately carried out, facilitating the installation of the adapter 121 and the sleeve rod assembly 11.

[0054] Referring to Figure 8 , in some embodiments, the self-moving device further includes a seal 40. The seal 40 is located between the second connecting member 113 and the outer side surface of the mounting plate 31; the seal 40 includes a nut 41 and an annular rubber ring 42. The inner ring shape of the annular rubber ring 42 is adapted to the outer ring shape of the nut 41, and the nut 41 is provided in the inner ring of the annular rubber ring 42.

[0055] Specifically, the outer side surface of the mounting plate 31 is the side of the mounting plate 31 facing the outside of the housing 20. The seal 40 is located outside the housing 20 and is clamped between the fixed seat 30 and the second connecting member 113 of the antenna sleeve rod 111, thereby preventing water from entering the connection between the antenna sleeve rod 111 and the fixed seat 30. The outer ring shape of the nut 41 is usually hexagonal. To adapt to the outer ring shape of the nut 41, the inner ring shape of the annular rubber ring 42 is designed to be hexagonal. In this way, the compression degree of the annular rubber ring 42 in each direction by the nut 41 is the same, and the force is the same, ensuring an effective seal can be formed on the contact surface, providing the best sealing performance, and also reducing the risk of stress concentration, thereby extending the service life of the seal 40. When combining, the nut 41 squeezes the rubber and is embedded in the inner ring of the annular rubber ring 42, so that a sealed state is formed between the nut 41 and the annular rubber ring 42. Adopting the form of combining the nut 41 and the annular rubber ring 42 to form the seal 40 can simultaneously play the roles of waterproofing and fastening, reducing the installation steps of the connection structure.

[0056] In some embodiments, the annular rubber ring 42 is an annular silicone rubber ring.

[0057] Specifically, the material of the annular rubber ring 42 is silicone. Silicone has a low glass transition temperature and can still maintain its softness and elasticity at low temperatures, is not easy to freeze or solidify, and can maintain its physical and chemical stability. Therefore, silicone can provide effective sealing performance even in a relatively low temperature or even frozen environment.

[0058] Refer to together Figure 6 and Figure 7 In some embodiments, the fixing base 30 further includes a fixing block 32. The fixing block 32 is provided with a second mounting hole, and the outer shell 20 has a third mounting hole corresponding to the second mounting hole. The fixing base 30 is fixed to the outer shell 20 through the second mounting hole and the third mounting hole.

[0059] Specifically, the fixing block 32 is used to fix the fixing base 30 on the outer shell 20. A second mounting hole 321 for installing a screw is formed in the fixing block 32, and a third mounting hole 23 is formed at a corresponding position on the outer shell 20. During installation, after the hook 311 of the fixing base 30 is hooked onto the clamping plate 21 of the outer shell 20, the second mounting hole 321 corresponds to the first mounting hole 312. A screw is tightly locked in the first mounting hole 312 and the second mounting hole 312, so as to fix the fixing base 30 on the outer shell 20. In this way, a connection portion for connecting the antenna assembly 10 is formed on the outer shell 20. When disassembling and assembling the antenna, the fixing base 30 does not need to be disassembled, and only needs to be installed through the first mounting hole 312. Preferably, two second mounting holes 321 are provided, and two corresponding third mounting holes 23 are also provided, which can make the installation of the fixing base 30 more stable.

[0060] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the embodiments of the present invention, and should all be included in the protection scope of the present invention.
