Home antennas for smart IoT transmission and communication

Abstract

This utility model discloses a home antenna for smart IoT transmission communication. The antenna module has a threaded adapter hole on its top. The clamping device includes a sleeve and a stretch pin. Both the threaded adapter hole and the stretch pin allow the antenna module's feed bus to pass through. The upper end of the sleeve has multiple rubber fingers spaced circumferentially. These rubber fingers grip the stretch pin and use their elasticity to clamp the ceiling mounting hole. Thus, the ceiling, sleeve, and stretch pin are relatively stationary, allowing the threaded adapter hole to screw onto the stretch pin. The antenna module screws onto the stretch pin and presses it against the ceiling, causing the stretch pin to point downwards and stretching the upper end of the sleeve. The stretch pin drives the rubber fingers to clamp the ceiling mounting hole. Compared to existing technologies, the antenna module is connected to the ceiling via the clamping device, eliminating the need to disassemble the ceiling for antenna maintenance.

Description

Technical Field

[0001] This utility model relates to communication devices, and more particularly to a home antenna for smart Internet of Things (IoT) transmission communication. Background Technology

[0002] As smart homes become increasingly popular, symbiotic home antennas (ceiling antennas) are also becoming more common.

[0003] In the prior art, a screw is integrally formed on the top of the antenna module. The screw passes through the ceiling and is connected to a nut on the inside of the ceiling (i.e., on top of the ceiling) to complete the installation and fixation of the antenna module, thereby installing the ceiling to the building ceiling.

[0004] The ceiling is made of large-sized profiles. In the existing technology, when the antenna module needs to be disassembled and maintained later, the ceiling needs to be removed to disassemble the antenna module. Utility Model Content

[0005] The present invention aims to solve at least one of the technical problems mentioned above, and provides a home antenna for smart IoT transmission communication, with the antenna module being easier to disassemble and maintain later.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0007] A smart IoT transmission communication home antenna includes an antenna module and a clamping device. The antenna module has a threaded adapter hole on its top. The clamping device includes a sleeve and a stretch pin. Both the threaded adapter hole and the stretch pin allow the feed bus of the antenna module to pass through. The upper end of the sleeve has multiple rubber fingers spaced circumferentially. These rubber fingers are used to grip the stretch pin and use their elasticity to clamp the mounting hole in the ceiling. That is, the ceiling, the sleeve, and the stretch pin are relatively stationary, allowing the threaded adapter hole to screw onto the stretch pin. The antenna module is used to screw onto the stretch pin and press it against the ceiling, causing the stretch pin to point downwards and stretching the upper end of the sleeve. The stretch pin drives the multiple rubber fingers to squeeze and block the mounting hole in the ceiling.

[0008] Compared with the prior art, the advantages of this application include: the antenna module is connected to the ceiling via a clip, so the ceiling does not need to be disassembled during antenna maintenance.

[0009] As an improvement to the above technical solution, the end of the expansion pin that is held by the multiple rubber fingers is provided with multiple anti-rotation protrusions spaced apart in the circumferential direction. The anti-rotation protrusions are used to limit the expansion pin to be stationary relative to the ferrule.

[0010] As an improvement to the above technical solution, the sleeve includes a metal washer and a rubber finger sleeve, the rubber finger sleeve wraps around the metal washer, and the rubber finger sleeve is provided with a plurality of rubber fingers.

[0011] As an improvement to the above technical solution, the outer peripheral wall of the upper end of the metal washer is provided with a plurality of anti-loosening protrusions distributed circumferentially, the rubber finger sleeve wraps around the upper end of the metal washer, and the metal washer is used to stop under the ceiling.

[0012] As an improvement to the above technical solution, the outer wall of the expansion pin is provided with at least two limiting grooves spaced apart along the circumference, and the metal washer is provided with at least two anti-disengagement protrusions that are correspondingly limited in the limiting grooves. The limiting grooves are used to prevent the expansion pin from disengaging from the sleeve, so that the rubber finger maintains a natural or outward-pointing posture.

[0013] As an improvement to the above technical solution, the antenna module includes a low-frequency vibrator, an insulating block, and a high-frequency vibrator arranged sequentially from top to bottom. The high-frequency vibrator is engaged with the insulating block, and the insulating block is threadedly connected to the high-frequency vibrator.

[0014] As an improvement to the above technical solution, the antenna module includes a substrate, an antenna cover, a reflector, a low-frequency vibrator, and a high-frequency vibrator. The reflector, the low-frequency vibrator, and the high-frequency vibrator constitute the antenna body. The substrate is screwed to the antenna cover. The substrate and the antenna cover together clamp the periphery of the reflector. The substrate is provided with the threaded adapter hole.

[0015] As an improvement to the above technical solution, the reflector is provided with a limiting block, which is used for inserting the card substrate. Attached Figure Description

[0027] Antenna module 300, substrate 310, threaded adapter hole 311, antenna cover 320, reflector 330, limiting block 331, low-frequency vibrator 340, insulating connecting block 350, high-frequency vibrator 360. Detailed Implementation

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] Reference Figures 1 to 4 This utility model provides a smart IoT transmission communication home antenna, including an antenna module 300 and a retainer 200. The top of the antenna module 300 is provided with a threaded adapter hole 311. The retainer 200 includes a retaining sleeve 210 and a tension pin 220. Both the threaded adapter hole 311 and the tension pin 220 allow the feed bus of the antenna module 300 to pass through. The upper end of the retaining sleeve 210 has multiple rubber fingers 212a distributed circumferentially, which are used to grip the tension pin 220. 20. The multiple rubber fingers 212a are used to block the mounting holes 110 of the ceiling 100 by their own elasticity. That is, the ceiling 100, the sleeve 210 and the expansion pin 220 are relatively stationary, so that the threaded adapter hole 311 can be screwed onto the expansion pin 220. The antenna module 300 is used to screw onto the expansion pin 220 and press against the ceiling 100, so that the expansion pin 220 is downward and pulls the upper end of the sleeve 210. The expansion pin 220 drives the multiple rubber fingers 212a to block the mounting holes 110 of the ceiling 100.

[0030] Regarding the upper end of the plug 200, which uses its own elasticity to plug the mounting hole 110 of the ceiling 100, it is generally understood that the diameter of the mounting hole 110 of the ceiling 100 is slightly smaller than the outer circle defined by the natural state of the multiple rubber fingers 212a. For example, if the plug 200 is 30mm in size, and the mounting hole 110 of the ceiling 100 is also drilled with a 30mm drill bit, the outer circle defined by the multiple rubber fingers 212a in their natural state is actually 30+mm, such as 32mm.

[0031] Reference Figure 1 , Figure 2 , Figure 5 and Figure 6 As is generally known, the antenna module 300 includes a substrate 310, an radome 320, a reflector 330, a low-frequency vibrator 340, a high-frequency vibrator 360, a low-frequency feed line electrically connected to the low-frequency vibrator 340, and a high-frequency feed line electrically connected to the high-frequency vibrator 360. The substrate 310 and the radome 320 form the antenna cavity. The reflector 330, the low-frequency vibrator 340, and the high-frequency vibrator 360 are arranged sequentially from top to bottom and form the antenna body. The low-frequency vibrator 340 and the high-frequency vibrator 360 are insulated from each other and connected. The antenna body is installed in the antenna cavity. The high-frequency feed line and the low-frequency feed line extend out of the substrate 310 and form a feed bus.

[0032] Reference Figure 1 , Figure 2 The operation process of this utility model can be as follows:

[0033] In the newly installed antenna module 300, the feed bus passes through the threaded adapter hole 311, the plug 200, and the mounting hole 110 of the ceiling 100. The plug 200 is inserted into the mounting hole 110 of the ceiling 100, that is, the plug 200 is pre-plugged into the mounting hole 110 of the ceiling 100. At this time, the outer periphery defined by multiple rubber fingers 212a supports and blocks the mounting hole 110 of the ceiling 100, and the inner periphery holds the expansion pin 220. The ceiling 100, the plug 210, and the expansion pin 220 are relatively stationary. Therefore, the antenna module 300 is further rotated in the forward direction, so that the antenna module 300 is rotated to fit the expansion pin 220. The upper end of the antenna module 300 is pressed against the ceiling 100, and the expansion pin 220 is pulled downward, so that multiple rubber fingers 212a are expanded. Multiple rubber fingers 212a further firmly squeeze and block the mounting hole 110 of the ceiling 100.

[0034] The antenna module 300 is attached to the ceiling 100 at its upper end, thus realizing a ceiling-mounted antenna.

[0035] For maintenance and disassembly, reverse the rotation of the antenna module 300 to disengage it from the expansion pin 220. The feed bus has a certain redundancy within the ceiling 100 to allow the antenna module 300 to be separated from the jammer 200 and the ceiling 100 to a certain extent.

[0036] Among them, the antenna module 300 is rotated away from the expansion pin 220, the expansion pin 220 can be retracted upwards, and multiple rubber fingers 212a can be retracted. Even if the rubber fingers 212a are retracted to their natural state, the multiple rubber fingers 212a still block the mounting holes 110 of the ceiling 100.

[0037] During maintenance and reinstallation, the ceiling 100, the clip 210, and the expansion pin 220 are relatively stationary. The antenna module 300 is rotated in the forward direction, causing the antenna module 300 to be fitted with the expansion pin 220. The upper end of the antenna module 300 is pressed against the ceiling 100, and the expansion pin 220 is pulled downward, causing multiple rubber fingers 212a to expand. The multiple rubber fingers 212a further firmly block the mounting holes 110 of the ceiling 100.

[0038] Compared with the prior art, the beneficial effects of this application include: the antenna module 300 is connected to the ceiling 100 through the clamp 200, and the ceiling 100 does not need to be disassembled during antenna maintenance.

[0039] Reference Figure 4 In some embodiments of this utility model, the end of the expansion pin 220 held by the plurality of rubber fingers 212a is provided with a plurality of anti-rotation protrusions 221 spaced apart along the circumference. The anti-rotation protrusions 221 are used to limit the expansion pin 220 to be stationary relative to the retaining sleeve 210. That is, when the antenna module 300 is screwed onto the lower end of the expansion pin 220, the ceiling 100 and the retaining sleeve 210, i.e., the expansion pin 220, are all stationary. The antenna module 300 screws onto the expansion pin 220 like a nut. Specifically, the anti-rotation protrusions 221 can be abutted by the rubber fingers 212a or can be locked between two rubber fingers 212a, so that the expansion pin 220 cannot rotate relative to the retaining sleeve 210.

[0040] Reference Figure 3 , Figure 4 In some embodiments of this utility model, the sleeve 210 includes a metal washer 211 and rubber finger sleeves 212. The rubber finger sleeves 212 wrap around the metal washer 211. For example, during the manufacturing of the sleeve 210, the metal washer 211 is pre-placed into the extrusion mold, and the rubber finger sleeves 212 wrap around the metal washer 211 during extrusion molding. The rubber finger sleeves 212 are provided with multiple rubber fingers 212a. When the expansion pin 220 retracts or depresses, the rubber finger sleeves 212 remain cylindrical, and multiple rubber fingers 212a continuously support the mounting holes 110 of the ceiling 100.

[0041] Reference Figure 3 , Figure 4In some embodiments of this utility model, the outer peripheral wall of the upper end of the metal washer 211 is provided with a plurality of anti-loosening protrusions 211a distributed circumferentially. The rubber finger sleeve 212 wraps around the upper end of the metal washer 211, and the metal washer 211 is used to stop below the ceiling 100. In this utility model, the rubber finger sleeve 212 and the metal washer 211 are firmly connected. During the process of the expansion pin 220 being pulled down by the antenna module 300, the metal washer 211 is stopped and cannot move upward, and the sleeve 210 is stable and does not move upward, effectively ensuring that the expansion pin 220 moves downward relative to the rubber finger sleeve 212, effectively ensuring that the plurality of rubber fingers 212a are effectively supported externally, so that the rubber finger sleeve 212 stably blocks the mounting hole 110 of the ceiling 100.

[0042] Reference Figure 3 , Figure 4 In some embodiments of this utility model, the outer wall of the expansion pin 220 is provided with at least two limiting grooves 222 spaced circumferentially, and the metal washer 211 is provided with at least two anti-detachment protrusions 211b that are correspondingly limited in the limiting grooves 222. The limiting grooves 222 are used to prevent the expansion pin 220 from detaching from the sleeve 210, so that the rubber finger 212a maintains a natural or outward-pointing posture. When the plug 200 is pre-plugged into the mounting hole 110 of the ceiling 100, the expansion pin 220 and the sleeve 210 cannot detach, which also makes the rubber finger 212a stably plug the mounting hole 110 of the ceiling 100. When the antenna module 300 rotates to rotate the expansion pin 220, the expansion pin 220 slides downward relative to the sleeve 210 along the limiting groove 222.

[0043] Reference Figure 3 , Figure 4 Specifically, the expansion pin 220 is provided with an inlet / outlet groove 223 that connects to the limiting slide groove 222; the assembly process of the stopper 200 is as follows: the sleeve 210 (anti-detachment protrusion) is sleeved onto the expansion pin 220 along the inlet / outlet groove 223, and the sleeve 210 or the expansion pin 220 is rotated around a certain angle so that the anti-detachment protrusion of the sleeve 210 is limited in the limiting slide groove 222. From then on, without human intervention, the expansion pin 220 remains stationary relative to the sleeve 210 through friction or the anti-rotation protrusion 221, that is, the anti-detachment protrusion is not easily transferred to the inlet / outlet groove 223, and the expansion pin 220 stably limits the rubber finger 212a to a natural or outward-pointing posture.

[0044] Reference Figure 1 , Figure 2 , Figure 5 and Figure 6In some embodiments of this utility model, the antenna module 300 includes a low-frequency vibrator 340, an insulating block 350, and a high-frequency vibrator 360 arranged sequentially from top to bottom. The high-frequency vibrator 360 holds the insulating block 350, and the insulating block 350 is threadedly connected to the high-frequency vibrator 360. In this utility model, the assembly and processing of the antenna body is relatively convenient and inexpensive. Specifically, the high-frequency vibrator 360 has at least two pre-set locking fingers on its upper end, and a high-frequency feed line is welded to the upper end of the high-frequency vibrator 360. After the insulating block 350 solidifies, it is held by the high-frequency vibrator 360, and the high-frequency feed line passes through the insulating block 350. Furthermore, the high-frequency feed line passes through the low-frequency vibrator 340, and the insulating block 350 is threadedly connected to the low-frequency vibrator 340.

[0045] Reference Figure 1 , Figure 2 , Figure 5 and Figure 6 In some embodiments of this utility model, the antenna module 300 includes a substrate 310, an antenna cover 320, a reflector 330, a low-frequency vibrator 340, and a high-frequency vibrator 360. The reflector 330, the low-frequency vibrator 340, and the high-frequency vibrator 360 constitute the antenna body. The substrate 310 is screwed to the antenna cover 320. The substrate 310 and the antenna cover 320 together clamp the periphery of the reflector 330. The substrate 310 is provided with a threaded adapter hole 311.

[0046] In some practical applications, the low-frequency vibrator 340 is directly welded to the reflector 330; in other practical applications, an insulating sheet is riveted between the low-frequency vibrator 340 and the reflector 330.

[0047] To prevent the antenna module 300 from rotating relative to the substrate 310 during transportation and handling, refer to... Figure 1 , Figure 2 In some embodiments of this utility model, the reflector 330 is provided with a limiting block 331, which is used for the card substrate 310.

[0048] The above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Any modifications or equivalent substitutions that do not depart from the spirit and scope of this utility model should be covered within the scope of the technical solution of this utility model.
