Description

Technical Field

[0001] The present application relates to the technical field of road spikes, and in particular to a waterproof road spike. Background Art

[0002] Road studs are the most widely used delineators in traffic security markings. They are mainly installed in the middle of road markings or double yellow lines, and can guide or warn motor vehicle drivers. Existing road studs usually have a shell with an installation cavity inside. After various electronic components are arranged in the installation cavity, the electronic components are sealed by filling the installation cavity with sealing glue.

[0003] Since road studs are directly installed on the roadside, rain often washes away the road studs on rainy days, and the road studs are often immersed in water for a long time. Over time, as the road studs are used, the sealing glue of the potting shell is exposed to rainwater over a large area, and the sealing glue deforms when it encounters water, causing the shell of the road stud and the sealing glue of the potting shell to peel off and crack, or the sealing glue itself ages and cracks, causing water to enter the interior of the road stud along the gaps, and then corrode the electronic components. In addition, the strength of the sealing glue is low after solidification, which affects the structural strength of the road stud, which will reduce the life of the road stud. Utility Model Content

[0004] The present application provides a waterproof road stud, which can solve the problem that the road stud is easily infiltrated with water, resulting in a shortened service life of the road stud.

[0005] In order to solve the above technical problems, the present application provides a waterproof road spike, which comprises a shell, a reinforcement plate, a circuit board, a power supply, a light-emitting element, a first adhesive and a second adhesive; the shell comprises a main body and a positioning part; the top surface of the reinforcement plate abuts against the bottom surface of the main body; the positioning part is connected to the bottom surface of the main body, and the positioning part is arranged around the outer periphery of the reinforcement plate; the shape of the inner side surface of the positioning part matches the shape of the side surface of the reinforcement plate, so that the inner side surface of the positioning part can fit the side surface of the reinforcement plate; a guide groove is arranged at a position of the bottom surface of the main body close to the positioning part; the first adhesive is filled in the guide groove to bond the reinforcement plate and the shell; a groove is arranged at a position of the bottom surface of the main body away from the positioning part, and the groove cooperates with the reinforcement plate to form an installation cavity; the circuit board, the power supply, and the light-emitting element are arranged on a side of the installation cavity away from the reinforcement plate; a glue injection hole is arranged on the reinforcement plate, and the glue injection hole is arranged opposite to the groove, and the second adhesive can fill the installation cavity through the glue injection hole, so that the second adhesive can seal the circuit board, the power supply and the light-emitting element.

[0006] In one embodiment, the guide groove is arranged around the outer circumference of the groove and is spaced apart from the groove, and the guide groove is enclosed into a closed shape.

[0007] In one embodiment, one end of the guide groove away from the groove extends to the positioning portion.

[0008] In one embodiment, the waterproof road stud further includes a solar panel, and the solar panel is arranged on a side of the installation cavity away from the reinforcing plate.

[0009] In one embodiment, the waterproof road stud further includes a third adhesive, which is made of a transparent or translucent material, and is used to fix the solar panel to a side of the installation cavity away from the reinforcing plate.

[0010] In one embodiment, the third adhesive is configured as epoxy resin.

[0011] In one embodiment, the first adhesive is configured as silicone.

[0012] In one embodiment, the second adhesive is configured as an electronically insulating sealant.

[0013] In one embodiment, the main body and the positioning portion are integrally formed.

[0014] In one embodiment, the height of the positioning portion is consistent with the height of the reinforcing plate.

[0015] The present application provides a waterproof road spike, which comprises a shell, a reinforcement plate, a circuit board, a power supply, a light-emitting element, a first adhesive and a second adhesive; the shell comprises a main body and a positioning portion; the top surface of the reinforcement plate abuts against the bottom surface of the main body; the positioning portion is connected to the bottom surface of the main body, and the positioning portion is arranged around the outer periphery of the reinforcement plate; the shape of the inner side surface of the positioning portion matches the shape of the side surface of the reinforcement plate, so that the inner side surface of the positioning portion can fit the side surface of the reinforcement plate; a guide groove is arranged at a position of the bottom surface of the main body close to the positioning portion; the first adhesive is filled in the guide groove to bond the reinforcement plate and the shell; a groove is arranged at a position of the bottom surface of the main body away from the positioning portion, and the groove cooperates with the reinforcement plate to form an installation cavity.

In addition, the reinforcing plate has a higher strength than the second adhesive, which can make the road stud more resistant to pressure, improve the structural strength of the road stud, and thus improve the life of the road stud.

[0021] The present application is further described in detail below by specific embodiments in conjunction with the accompanying drawings. Wherein similar elements in different embodiments adopt associated similar element numbers. In the following embodiments, many detailed descriptions are intended to enable the present application to be better understood. However, those skilled in the art can easily recognize that some of the features can be omitted in different situations, or can be replaced by other elements, materials, and methods. In some cases, some operations related to the present application are not shown or described in the specification, in order to avoid the core part of the present application being overwhelmed by too much description, and for those skilled in the art, it is not necessary to describe these related operations in detail, and they can fully understand the related operations based on the description in the specification and the general technical knowledge in the art.

[0022] In addition, the features, operations or characteristics described in the specification can be combined in any appropriate manner to form various implementations, and the operation steps involved in each embodiment can also be replaced or adjusted in a sequence in a manner that is obvious to those skilled in the art. Therefore, the specification and drawings are only for the purpose of clearly describing a certain embodiment and do not mean that the composition and / or sequence are necessary.

The "connection" and "coupling" mentioned in this application, unless otherwise specified, include direct and indirect connections (couplings).

[0024] like Figure 1-5The present application provides a waterproof road spike. In the present application, the waterproof road spike can be referred to as a road spike. In the directional terms of the present application, the directions of "top surface", "bottom surface" and "side surface" all refer to the reference directions when the waterproof road spike is actually used (for example, Figure 1 The placement of the road spikes is a schematic diagram of the actual placement in use. Figure 2-5 The spikes are Figure 1 The directional terms used are intended to better and more clearly illustrate and understand the embodiments of the present application, rather than to indicate or imply that the device or element referred to must have a specific orientation, be constructed and operate in a specific orientation, and therefore should not be understood as a limitation on the embodiments of the present application.

[0025] The waterproof road stud comprises a housing 10, a reinforcing plate 20, a circuit board 30, a power source 40, a light emitting element 50, a first adhesive (not shown) and a second adhesive (not shown).

[0026] like Figure 4 and Figure 5 As shown, the shell 10 includes a main body 11 and a positioning portion 12. The material of the shell 10 may be, for example, but not limited to, polycarbonate. Preferably, the main body 11 and the positioning portion 12 are integrally formed. The positioning portion 12 is connected to the bottom surface 111 of the main body 11, and the positioning portion 12 is arranged to protrude from the bottom surface 111 of the main body 11. The top surface of the reinforcing plate 20 abuts against the bottom surface 111 of the main body 11, and the positioning portion 12 is arranged around the periphery of the reinforcing plate 20. In one embodiment, the height of the positioning portion 12 is consistent with the height of the reinforcing plate 20. The positioning portion 12 is surrounded in a ring shape. In the present application, the ring shape does not only refer to a circular ring, but may also be other shapes. For example, the positioning portion 12 may be a square frame, or other regular and irregular shaped rings. The ring shape only means that the positioning portion 12 surrounds the periphery of the reinforcing plate 20 in a closed shape, and does not limit the specific shape of the closed shape.

[0027] The shape of the inner side surface 121 of the positioning portion 12 matches the shape of the side surface 21 of the reinforcing plate 20, so that the inner side surface 121 of the positioning portion 12 can fit the side surface 21 of the reinforcing plate 20. That is, the specific shape of the ring of the positioning portion 12 corresponds to the shape of the reinforcing plate 20, wherein the "inside" and "outside" of the positioning portion 12 are relative to the ring structure. The inner side surface 121 of the positioning portion 12 and the side surface 21 of the reinforcing plate 20 should be tightly fitted, so that it is difficult for water droplets to penetrate from between the inner side surface 121 of the positioning portion 12 and the side surface 21 of the reinforcing plate 20. In the present application, the positioning portion 12 cooperates with the bottom surface 111 of the main body 11 to form a space in which the reinforcing plate 20 can be installed, and the space corresponds to the shape of the reinforcing plate 20, so that the reinforcing plate 20 can be in close contact with the positioning portion 12, reducing the possibility of water droplets penetrating from between the positioning portion 12 and the reinforcing plate 20.

[0028] A guide groove 112 is provided at a position of the bottom surface 111 of the main body 11 close to the positioning portion 12. Since the positioning portion 12 is annular, the position of the bottom surface 111 of the main body 11 close to the positioning portion 12 is roughly the edge position of the bottom surface 111 of the main body 11. The first adhesive is filled in the guide groove 112 to bond the reinforcing plate 20 and the housing 10. A groove 113 is provided at a position of the bottom surface 111 of the main body 11 away from the positioning portion 12. Since the positioning portion 12 is annular, the position of the bottom surface 111 of the main body 11 away from the positioning portion 12 is roughly the middle of the bottom surface 111 of the main body 11. The groove 113 cooperates with the reinforcing plate 20 to form the mounting cavity 60. The circuit board 30, the power supply 40, and the light-emitting element 50 are arranged on the side of the mounting cavity 60 away from the reinforcing plate 20. The reinforcing plate 20 is provided with a glue injection hole 22, which is arranged opposite to the groove 113. The second adhesive can fill the mounting cavity 60 through the glue injection hole 22, so that the second adhesive can seal the circuit board 30, the power supply 40, and the light-emitting element 50. Preferably, the second adhesive fills the entire mounting cavity 60 and fills at least part of the glue injection hole 22 to prevent water from flowing into the interior of the mounting cavity 60 from the glue injection hole 22.

[0029] The present application sets a positioning portion 12 on the main body 11 of the shell 10. The positioning portion 12 and the main body 11 can form an installation space that fits tightly with the reinforcing plate 20. The reinforcing plate 20 and the positioning portion 12 fit tightly together, which can prevent rainwater from flowing into the road spike from the gap between the reinforcing plate 20 and the positioning portion 12.

[0030] The present application provides a guide groove 112 at the edge of the bottom surface 111 of the main body 11, and uses a first adhesive to fill the guide groove 112. On the one hand, the first adhesive can bond the reinforcing plate 20 and the shell 10; on the other hand, the first adhesive and the guide groove 112 can serve as an important line of defense for the road spike to block water; because the gap between the reinforcing plate 20 and the positioning part 12 is linear, the water molecules that penetrate into the road spike from the gap between the reinforcing plate 20 and the positioning part 12 will first contact the first adhesive, and the water molecules and the first adhesive are also in linear contact, and the first adhesive will not directly contact water over a large area, reducing the possibility of large-scale deformation (expansion and contraction) of the first adhesive when it encounters water, and also reducing the possibility of cracking of the first adhesive. The guide groove 112 can also act as a "dam" to further prevent the water molecules that contact the first adhesive from continuing to penetrate into the interior of the road spike. Therefore, this structure improves the waterproof ability of the road spike and increases the life of the road spike.

[0031] In addition, by adding a reinforcing plate 20 to the bottom surface 111 of the main body 11, most of the rainwater flowing to the bottom of the road spike will be blocked by the reinforcing plate 20, and it is difficult for the rainwater to directly contact the second adhesive over a large area, thereby reducing the problem of cracking caused by the second adhesive being soaked in water for a long time and over a large area. Moreover, the reinforcing plate 20 has a higher strength than the second adhesive, and the addition of the reinforcing plate 20 can make the road spike more resistant to pressure, improve the structural strength of the road spike, and thus increase the life of the road spike. The material of the reinforcing plate 20 can be selected from hard metals or alloy materials such as aluminum and steel, for example.

[0032] The first adhesive needs to be a waterproof colloid, and in one embodiment, the first adhesive is configured as silica gel. The second adhesive needs to be a glue with low corrosion to electronic components, and in one embodiment, the second adhesive is configured as electronic insulating sealant, and its components can be the components of existing electronic insulating sealants.

[0033] The improvement of the road spike of the present application is particularly suitable for ultra-thin road spikes. Since the thickness of the sealant of ultra-thin road spikes is relatively thin, rainwater can more easily penetrate into the electronic components through the sealant. The improvement of the structure of the present application can greatly enhance the waterproof ability and structural strength of ultra-thin road spikes.

[0034] The inventor has conducted experimental tests to compare the structural strength of the existing solar road studs and the solar road studs of the present invention. The test results are as follows, indicating that the structural strength of the solar road studs after the structural improvement of the present invention is greatly improved.

[0037]

[0038] In one embodiment, if Figure 5 As shown, the guide groove 112 is arranged around the outer circumference of the groove 113 and is spaced apart from the groove 113, and the guide groove 112 is enclosed into a closed shape. By enclosing the guide groove 112 into a closed shape, the possibility of rainwater infiltrating into the groove 113 from various positions around can be reduced, which is conducive to further improving the waterproof ability of the road stud. The guide groove 112 is spaced apart from the groove 113 so that the inner wall of the guide groove 112 close to the groove 113 can act as a "dam", further preventing water molecules that have contacted the first adhesive from continuing to penetrate into the interior of the road stud.

[0039] In one embodiment, one end of the guide groove 112 away from the groove 113 extends to the positioning portion 12, that is, the positioning portion 12 and the main body 11 cooperate to form the guide groove 112. By extending the guide groove 112 to the positioning portion 12, it is beneficial for the first adhesive to flow into the gap between the reinforcing plate 20 and the positioning portion 12, so as to further seal the gap between the reinforcing plate 20 and the positioning portion 12.

[0040] In one embodiment, the waterproof road stud further includes a solar panel 70, which is disposed on a side of the installation cavity 60 away from the reinforcing plate 20. The solar panel 70, the power supply 40, and the light-emitting element 50 are all electrically connected to the circuit board 30. The solar panel 70 can obtain solar energy during the day and store it in the power supply 40, and can supply power to the light-emitting element 50 through the power supply 40 at night, so that the road stud emits light. Preferably, the main body 11 of the housing 10 is transparent or translucent.

[0041] In one embodiment, the waterproof road stud further includes a third adhesive (not shown), which is used to fix the solar panel 70 to the side of the installation cavity 60 away from the reinforcing plate 20. Preferably, the third adhesive is disposed between the solar panel 70 and the main body 11. In order to prevent the third adhesive from blocking the solar panel 70 from obtaining solar energy, the third adhesive is configured to be transparent or translucent. In one embodiment, the third adhesive is configured as epoxy resin.

[0042] The production process of the waterproof road studs of this application is as follows:

[0043] 1. First, use the third adhesive to fix each electronic component in the mounting cavity 60, and then fill a layer of the second adhesive on the surface of each electronic component;

[0044] Since the height of the mounting cavity 60 in the ultra-thin road stud is relatively small, if a layer of the second adhesive is not firstly cast on the surface of the electronic component, when the second adhesive is subsequently cast from the casting hole 22, it is difficult for the second adhesive to flow in the mounting cavity 60 due to the different surface tension between the second adhesive and the electronic component, and the entire mounting cavity 60 cannot be filled. However, if a layer of the second adhesive is firstly cast on the surface of each electronic component, when the second adhesive is subsequently cast from the casting hole 22, the second adhesive is more likely to flow when it contacts the pre-cast layer of the second adhesive with the same surface tension, which is conducive to the second adhesive filling the entire mounting cavity 60, thereby improving the waterproof ability and sealing performance of the road stud.

[0045] 2. Fill the first adhesive into the guide groove 112;

[0046] 3. Install the reinforcing plate 20 on the bottom of the housing 10, and fix the reinforcing plate 20 and the housing 10 together with screws;

[0047] 4. Fill the installation cavity 60 with the second adhesive through the glue injection holes 22 on the reinforcing plate 20 .

[0048] The above specific examples are used to illustrate the present invention, which are only used to help understand the present invention and are not intended to limit the present invention. For those skilled in the art of the present invention, some simple deductions, deformations or substitutions can be made based on the idea of ​​the present invention.
