[0028] Reference below Figure 1-Figure 4 A road sign antenna 100 according to an embodiment of the present invention is described.

[0029] like Figure 1-Figure 4 As shown, the road sign antenna 100 according to the embodiment of the present utility model includes: a communication module 10 , a housing 20 and a sealing member 30 .

[0030] A mounting groove 21 is formed on one side of the housing 20 , and the communication module 10 is disposed in the mounting groove 21 . The sealing member 30 covers the communication module 10 and is disposed in the mounting groove 21 and is suitable for sealing the mounting groove 21 .

[0031] It should be noted that after the communication module 10 is set in the installation groove 21 of the shell 20, a sealing member 30 will be covered thereon, so that the sealing member 30 can also seal the installation groove 21 when covering the communication module 10. In this way, after the road sign antenna 100 is set on the manhole cover, it is not easy for water to enter the installation groove 21, thereby avoiding damage to the communication module 10, and further allowing the communication module 10 to operate normally.

[0032] Furthermore, the communication module 10 is arranged in the installation groove 21 formed in the shell 20, so that the shell 20 can play a certain protective role on the communication module 10, so that the communication module 10 is not easily damaged after the road sign antenna 100 is arranged on the manhole cover.

[0033] Thus, the communication module 10 can be set in the installation groove 21 of the shell 20, and the seal 30 can seal the installation groove 21 when the cover is set on the communication module 10, so that when the road sign antenna 100 is set on the manhole cover, water is not easy to enter the installation groove 21, thereby avoiding damage to the communication module 10, and the shell 20 can also protect the communication module 10.

[0034] According to the road sign antenna 100 of the embodiment of the utility model, the communication module 10 is set in the installation groove 21 of the shell 20 and then sealed by the seal 30, so that the communication module 10 in the shell 20 will not be affected by the external environment. At the same time, after the communication module 10 is set in the installation groove 21, the shell 20 can protect the communication module 10, so that the communication module 10 is not easily damaged.

[0035] In some embodiments, Figure 3 As shown, the road sign antenna 100 also includes: an adhesive 40, which is located between the communication module 10 and the shell 20, one side of the adhesive 40 is connected to the bottom wall of the installation groove 21, and the other side is connected to the communication module 10 to fix the communication module 10 to the installation groove 21.

[0036] It should be noted that one side of the adhesive 40 will be connected to the communication module 10, and the other side of the adhesive 40 will be connected to the bottom wall of the mounting groove 21, so that the communication module 10 can be fixed in the mounting groove 21 through the adhesive 40, so that the communication module 10 can be more easily fixed in the mounting groove 21, thereby making the assembly of the road sign antenna 100 easier.

[0037] Furthermore, the adhesive member 40 can be constructed as a double-sided tape, which is attached to one side of the communication module 10. In this way, after the communication module 10 is placed in the mounting groove 21, it can be adhered to the mounting groove 21 by the double-sided tape, which makes the installation of the communication module 10 easier and also makes it difficult for the communication module 10 to detach from the mounting groove 21.

[0038] Thus, the adhesive 40 can fix the communication module 10 in the mounting groove 21 , so that the communication module 10 is not easily separated from the mounting groove 21 . Meanwhile, the adhesive 40 can make it easier to fix the communication module 10 in the mounting groove 21 .

[0039] In some embodiments, Figure 1-Figure 3 As shown, the mounting groove 21 is constructed as a recessed groove, and the housing 20 further includes a flange 22 surrounding the recessed groove, and a protrusion 23 is formed on the flange 22.

[0040] It should be noted that the mounting groove 21 is constructed as a sunken groove, so that the communication module 10 will not leak out after being set in the mounting groove 21, so that the mounting groove 21 can protect the communication module 10. At the same time, the shell 20 has a flange 22 surrounding the sunken groove, and a protrusion 23 is formed on the flange 22. When the shell 20 is fixed to the manhole cover by glue, the protrusion 23 on the flange 22 can increase the contact area between the flange 22 and the glue, so that the shell 20 can be fixed on the manhole cover more firmly, and then the shell 20 is not easy to detach from the manhole cover.

[0041] Therefore, the installation groove 21 is constructed as a sunken groove so that the communication module 10 can be protected to a certain extent after being set in the sunken groove, thereby making the communication module 10 not easily damaged, and the shell 20 also has a flange 22 surrounding the sunken groove, and a protrusion 23 is formed on the flange 22, so that when the shell 20 is fixed to the manhole cover by glue, the contact area between the flange 22 and the glue is larger, so that the shell 20 is fixed more firmly.

[0042] Furthermore, the mounting groove 21 is constructed as a sunken groove, so that when the communication module 10 is set in the mounting groove 21, the mounting groove 21 can guide the communication module 10, so that the communication module 10 can be more easily set in the mounting groove 21, thereby reducing the difficulty of assembling the road sign antenna 100, thereby improving the production efficiency of the road sign antenna 100.

[0043] Among them, the road sign antenna 100 is fixed on the manhole cover by glue. After the glue is applied on the manhole cover, the side of the shell 20 with the protrusion 23 is arranged toward the manhole cover. In this way, during the installation process, the glue can cover the protrusion 23 on the flange 22, thereby expanding the contact area between the glue and the shell 20, which can effectively improve the fixing effect of the road sign antenna 100, so that the road sign antenna 100 is not easy to detach from the manhole cover.

[0044] In some embodiments, Figure 1-Figure 3 As shown, there are multiple groups of protrusions 23 , which are distributed in sequence along the radial direction, and each group of protrusions 23 is arranged around the installation groove 21 .

[0045] It should be noted that there are multiple groups of protrusions 23, and the multiple groups of protrusions 23 are distributed in sequence along the radial direction of the shell 20, so that the contact area between the flange 22 and the glue can be larger, so that the glue can better fix the shell 20. At the same time, each group of protrusions 23 is arranged around the installation groove 21, so that after the shell 20 is fixed on the manhole cover, the multiple groups of protrusions 23 can make the shell 20 not easy to be opened.

[0046] Therefore, there are multiple groups of protrusions 23 and the multiple groups of protrusions 23 are distributed in sequence along the radial direction of the shell 20, so that the shell 20 is more secure when fixed on the manhole cover by glue. At the same time, each group of protrusions 23 is arranged around the installation groove 21, so that the shell 20 is not easy to be opened.

[0047] Furthermore, a plurality of protrusions 23 are formed on the flange 22, so that when the flange 22 is covered on the manhole cover coated with glue, the glue will enter into the gaps between the plurality of protrusions 23, thereby further increasing the contact area between the glue and the flange 22, thereby making the glue better for fixing the shell 20.

[0048] Among them, each group of protrusions 23 is arranged around the installation groove 21, so that after the flange 22 is bonded with glue, the shell 20 can be fixed by glue in all directions, so that the shell 20 will be subjected to force more evenly, and the road sign antenna 100 is not easy to fall off the manhole cover.

[0049] In some embodiments, Figure 1 As shown, the sealing member 30 is configured as a potting layer and is potted in the mounting groove 21 , and the surface of the potting layer is flush with a surface of one side of the housing 20 .

[0050] It should be noted that the seal 30 is constructed as a potting layer, so that after the seal 30 is potted in the mounting groove 21, the mounting groove 21 can be effectively sealed, so that water is not easy to enter the mounting groove 21, and the communication module 10 is not easily affected by water. At the same time, the surface of the potting layer is flush with the surface of one side of the shell 20, so that the shell 20 can be flush with the manhole cover when placed on the manhole cover, so that the shell 20 can be fixed to the manhole cover by glue more easily.

[0051] Therefore, the seal 30 is constructed as a potting layer that can play a good sealing role on the installation groove 21, so that water is not easy to enter the installation groove 21. At the same time, the surface of the potting layer is flush with the surface of one side of the shell 20, so that the shell 20 can be flush with the manhole cover when placed on the manhole cover, making it easier to fix the shell 20 to the manhole cover by glue.

[0052] Furthermore, the housing 20 can be fixed on top of the manhole cover by weather-resistant glue, which makes the signal coverage of the communication module 10 more uniform and less susceptible to interference, and also makes the communication module 10 easier to maintain in the subsequent process.

[0053] Among them, after the communication module 10 is set in the installation groove 21 of the shell 20, it will be sealed by the seal 30, so that the communication module 10 will not contact the external environment, so that the communication module 10 will not be affected by the external environment, and the road sign antenna 100 can adapt to various harsh environments.

[0054] In some embodiments, Figure 4 As shown, the other side surface of the housing 20 is configured as an arc-shaped convex surface 24 for buffering protection.

[0055] It should be noted that the other side surface of the shell 20 is constructed as an arc-shaped convex surface 24, that is, the side of the shell 20 facing away from the manhole cover is constructed as an arc-shaped convex surface 24, so that the shell 20 can perform buffering protection to protect the communication module 10 in the shell 20, that is, when the vehicle passes over the shell 20, the arc-shaped convex surface 24 can play a buffering role to protect the communication module 10 in the shell 20.

[0056] Therefore, the shell 20 is constructed such that one side of the arcuate convex surface 24 is the side of the shell 20 facing away from the manhole cover, so that when a vehicle passes over the shell 20 , the arcuate convex surface 24 can play a buffering role to protect the communication module 10 in the shell 20 .

[0057] Furthermore, when a vehicle passes by, the arc-shaped convex surface 24 of the shell 20 will be squeezed by the wheels and deformed to a certain extent, thereby buffering the impact force generated by the vehicle. In this way, the impact generated by the passing vehicle is prevented from affecting the communication module 10, thereby ensuring the normal operation of the communication module 10, and then the road sign antenna 100 can operate normally.

[0058] In some embodiments, Figure 4 As shown, a plurality of structural reinforcement portions 25 are formed on the arc-shaped convex surface 24 .

[0059] It should be noted that a plurality of structural reinforcement parts 25 are formed on the arcuate convex surface 24 , so that the structural strength of the arcuate convex surface 24 is higher, so that the shell 20 can withstand greater pressure, and further the shell 20 can better protect the communication module 10 inside the shell 20 .

[0060] Therefore, by forming a plurality of structural reinforcement portions 25 on the arc-shaped convex surface 24 , the structural strength of the arc-shaped convex surface 24 is made higher, so that the housing 20 can withstand greater pressure, thereby better protecting the communication module 10 .

[0061] In some embodiments, Figure 4 As shown, each structural reinforcement portion 25 defines an equilateral hexagonal surface.

[0062] It should be noted that each structural reinforcement portion 25 defines an equilateral hexagonal surface, so that multiple structural reinforcement portions 25 can be spliced ​​together, so that the multiple structural reinforcement portions 25 can better reinforce the arcuate convex surface 24, thereby making the structural strength of the arcuate convex surface 24 higher, which can better protect the communication module 10.

[0063] Therefore, each structural reinforcement portion 25 defines an equilateral hexagonal surface so that multiple structural reinforcement portions 25 can be spliced ​​together, thereby better reinforcing the arcuate convex surface 24 and further improving the structural strength of the arcuate convex surface 24, thereby better protecting the communication module 10.

[0064] Furthermore, the equihexagonal surfaces defined by each structural reinforcement portion 25 are of the same size, so that no gaps will appear when multiple structural reinforcement portions 25 are spliced ​​together, thereby better strengthening the structural strength of the shell 20, and then allowing the shell 20 to withstand greater pressure, so that the road sign antenna 100 can operate normally. At the same time, when multiple structural reinforcement portions 25 with equihexagonal surfaces are spliced ​​together, they will not affect the arc-shaped convex surface 24 of the shell 20, that is, the surface of the shell 20 can also be constructed as a arc-shaped convex surface 24, which makes the structural strength of the shell 20 higher.

[0065] In some embodiments, Figure 4 As shown, a plurality of structural reinforcement portions 25 are closely paved on the arc-shaped convex surface 24 .

[0066] It should be noted that a plurality of structural reinforcement parts 25 are densely laid on the arc-shaped convex surface 24, that is, the plurality of structural reinforcement parts 25 arranged on the arc-shaped convex surface 24 can cover the entire surface of the arc-shaped convex surface 24, thereby making the structural strength of the arc-shaped convex surface 24 higher, and further enabling the shell 20 to withstand greater pressure, thereby further protecting the communication module 10.

[0067] Thus, the plurality of structural reinforcement portions 25 can completely cover the surface of the arc-shaped convex surface 24 , thereby increasing the structural strength of the arc-shaped convex surface 24 , thereby enabling the housing 20 to withstand greater pressure, thereby further protecting the communication module 10 .

[0068] Furthermore, the arc-shaped convex surface 24 on the shell 20 and the structural reinforcement can increase the structural stability of the shell 20, so that the shell 20 can achieve the effect of pressure resistance and impact resistance. At the same time, this also enables the shell 20 to withstand a pressure of 1500 pounds, thereby better protecting the communication module 10.

[0069] In some embodiments, Figure 1-Figure 3 As shown, the communication module 10 includes a circuit board 11 and an antenna 12 . The antenna 12 is signal-connected to the circuit board 11 and is welded and fixed to a side of the circuit board 11 away from the mounting slot 21 .

[0070] It should be noted that the antenna 12 of the communication module 10 will be welded to the circuit board 11 and connected with signals, so that the connected communication module 10 can work normally. At the same time, after welding, the antenna 12 will be located on the side of the circuit board 11 away from the installation slot 21, so that the antenna 12 will not affect the installation of the communication module 10.

[0071] Therefore, the antenna 12 of the communication module 10 will be welded and fixed to the circuit board 11 while being connected to the circuit board 11 for signal connection, so that the antenna 12 will not be detached from the circuit board 11, thereby ensuring the normal operation of the communication module 10. At the same time, after welding, the antenna 12 will be located on the side of the circuit board 11 away from the installation groove 21, so that the antenna 12 will not affect the installation of the communication module 10.

[0072] Among them, after the road sign antenna 100 is set on the manhole cover, the antenna 12 of the communication module 10 can be arranged according to actual usage, such as extending the antenna 12 into the manhole cover to better protect the antenna 12, or placing the antenna 12 on the outside to obtain a better signal.
