Description

Technical Field

[0001] The present application relates to the technical field of solar road studs, and in particular to an externally embedded solar reflective road stud and a manufacturing method thereof. Background Art

[0002] The existing externally embedded reflective solar road studs have a shell, a road stud lamp, a reflector, etc. The shell has a lamp hole and a reflector mounting groove. The reflector mounting groove is located on the upper surface of the shell, and the lamp hole passes through the inside of the shell and the reflector mounting groove. When manufacturing an externally embedded reflective road stud, first insert the lamp head of the road stud lamp into the lamp hole from the inside of the road stud shell, then make the lamp head extend out of the reflector mounting groove, then apply glue on the light-emitting sheet, embed the reflector into the reflector mounting groove, and then install other parts.

[0003] For such an externally embedded reflective solar road stud, the reflector and the reflector mounting groove cannot be completely fitted, that is, there is a gap between the reflector and the shell, which makes the reflector easy to crack and break under external impact (such as being run over by a high-speed car), and has weak impact resistance; in addition, it is also due to this gap that the light-emitting sheet and the light-emitting sheet mounting groove are not completely solid structures, and the pressure resistance is low. Summary of the invention

[0004] The present application provides an externally embedded solar reflective road stud and a manufacturing method thereof, which can solve the problem that the road stud has a weak impact resistance and low compression resistance due to a gap between the reflective sheet and the shell.

[0005] In order to achieve the above objectives, this application adopts the following technical solutions:

[0006] The invention discloses an externally embedded solar energy reflective road stud, comprising a shell, a reflector, a road stud lamp and a light-emitting component. The shell has a cavity inside, and reflector mounting grooves are provided on the outer walls on both sides of the shell. The reflector is installed on the reflector mounting groove. The shell also has a lamp hole and a glue injection hole. The lamp hole and the glue injection hole each penetrate and connect the cavity and the reflector mounting groove. The aperture of the glue injection hole is larger than that of the lamp hole. The glue injection hole is used for injecting glue into the reflector mounting groove. The light-emitting component is installed in the cavity. The back of the reflector has a hollow lamp post. The lamp post is embedded in the lamp hole and the glue injection hole. The lamp head of the road stud lamp extends into the lamp post. The light-emitting component is used for absorbing sunlight and then driving the road stud lamp to emit light. The space between the reflector and the reflector mounting groove is filled with sealing glue.

[0007] Furthermore, it also includes an exhaust hole, which penetrates and connects the reflector installation groove and the bottom end of the shell body, and the exhaust hole is used to discharge the gas in the gap between the reflector and the reflector installation groove after glue filling.

[0008] Furthermore, the light-emitting component includes a solar panel, a battery and a controller. The solar panel and the battery are electrically connected, and the road stud light is also electrically connected to the solar panel and the battery through the controller. A transparent shell is installed on the top of the shell, and the solar panel is arranged close to the transparent shell.

[0009] Furthermore, the cavity of the shell is filled with potting glue, the potting glue wraps the light-emitting component, and the potting glue is transparent glue.

[0010] Furthermore, the cavity of the shell is filled with potting glue.

[0011] Furthermore, the road stud lights are LED lights.

[0012] A method for manufacturing an externally embedded solar reflective road stud comprises the following steps:

[0013] Use waterproof silicone to install the reflector on the reflector mounting slot. The waterproof silicone seals the reflector around.

[0014] Install the transparent shell and the solar panel on the top of the shell, use waterproof silicone to seal the four sides of the transparent shell, and the solar panel is located at the bottom of the transparent shell and fits the transparent shell;

[0015] Install the controller, battery and road stud lamp into the cavity of the housing, and put the lamp head of the road stud lamp into the lamp post on the back of the reflector;

[0016] Solder the circuit connections of the road spike lights, controller, solar panel and battery together;

[0017] Turn the housing upside down and perform the first potting. Inject the potting glue into the potting holes and lamp holes of the housing to fill the gap between the reflector and the reflector mounting groove.

[0018] After the potting glue of the first potting is solidified, the second potting is performed to fill the cavity of the shell with the potting glue;

[0019] After the second potting glue is cured, the preparation is completed.

[0020] Furthermore, before the first potting glue is cured, the reflective sheet mounting groove is vented through the vent hole.

[0021] The beneficial effects of this application are:

[0022] 1) The externally embedded solar reflective road stud of the present application is provided with a through-hole for potting glue between the cavity of the shell and the reflector mounting groove. The hole diameter of the potting glue hole is larger than the lamp hole. During manufacturing, more potting glue can be injected between the reflector and the reflector mounting groove through the potting glue hole. In this way, there is no extra gap between the reflector and the reflector mounting groove, and the two form a solid structure through the potting glue. Such a structure can ensure that the reflector has high-strength impact resistance and is not easily damaged under the impact of external forces.

[0023] 2) The reflector and the reflector mounting groove are solid structures, which have better pressure resistance and waterproof performance and are durable. BRIEF DESCRIPTION OF THE DRAWINGS

[0028] The present application is further described in detail below through specific implementation methods in conjunction with the accompanying drawings.

[0029] An externally embedded solar reflective road stud comprises a housing 1, a reflector 2, a road stud lamp 3 and a light emitting assembly 4. The housing 1 has a cavity 11 inside, and the outer walls on both sides of the housing 1 have inclined reflector mounting grooves 12, and the reflector 2 is mounted on the reflector mounting grooves 12. The housing 1 also has a glue injection hole 13 and a lamp hole 14, and the lamp hole 14 and the glue injection hole 13 each penetrate and connect the cavity 11 and the reflector mounting groove 12. The aperture of the glue injection hole 13 is larger than the aperture of the lamp hole 14, so that glue can be injected from the cavity 11 into the reflector mounting groove 12 through the glue injection hole 13.

[0030] The light-emitting assembly 4 is installed in the cavity 11, and the back of the reflector 2 has a hollow lamp post 21. When the reflector 2 is installed on the reflector installation groove 12, the lamp post 21 is embedded in the lamp hole 14 and the glue injection hole 13 of the housing 1, and the lamp head of the road spike lamp 3 extends into the lamp post 21. In this embodiment, the road spike lamp 3 adopts an LED lamp. After the light-emitting assembly 4 absorbs solar energy, it can directly power the road spike lamp 3 on the one hand, and on the other hand, it can be stored as electrical energy for power supply at night or on rainy days.

[0031] The space between the reflective sheet 2 and the reflective sheet installation groove 12 is filled with potting glue, so that the reflective sheet 2 and the reflective sheet installation groove 12 are solid structures without any gap.

[0032] The externally embedded solar reflective road stud also includes an exhaust hole 15, which passes through the reflective sheet mounting groove 12 and the bottom end of the shell 1. After the glue is poured and before the potting glue is cured, the gas between the reflective sheet 2 and the reflective sheet mounting groove 12 and the gas contained in the potting glue can be discharged through the exhaust hole 15.

[0033] The light-emitting assembly 4 includes a solar panel 41, a battery 42 and a controller (not shown in the figure). The solar panel 41 and the battery 42 are electrically connected, and the road stud light 3 is electrically connected to the solar panel 41 and the battery 42 respectively through the controller. The top of the housing 1 is open, and the opening is covered with a transparent shell 5. The solar panel 41 is arranged close to the transparent shell 5 to absorb sunlight. After absorbing sunlight, the solar panel 41 converts it into electrical energy, and then directly powers the road stud light 3, or transmits it to the battery 42, and the battery 42 stores the electrical energy.

[0034] The cavity 11 of the housing 1 is also filled with potting glue, which wraps the light emitting component 4 to prevent liquid from penetrating into the light emitting component 4. The cavity 11 is filled with potting glue, so that the entire road stud becomes a solid body, thereby improving the impact resistance and pressure resistance of the entire road stud.

[0035] A method for manufacturing an externally embedded solar luminous road stud comprises the following steps:

[0036] S100: Install reflective sheeting

[0037] Waterproof silica gel is applied on the reflector installation groove 12 , and the reflector 2 is embedded and installed in the reflector installation groove 12 . The waterproof silica gel adheres the reflector 2 and seals the surrounding of the reflector 2 .

[0038] When the reflective sheet 2 is installed into the reflective sheet installation groove 12 , the hollow lamp post 21 on the back side of the reflective sheet 2 is embedded into the lamp hole 14 and the glue injection hole 13 .

[0039] S200: Installing transparent shell and solar panels

[0040] When installing the transparent shell 5, waterproof silica gel is applied to the edge of the top opening of the shell, and the transparent shell 5 is bonded to the top of the shell through the waterproof silica gel and covers the top opening of the shell. The waterproof silica gel seals the four sides of the transparent shell 5. Before installing the transparent shell 5, the solar panel 41 is assembled at the lower end of the transparent shell 5, and the solar panel 41 is placed in close contact with the transparent shell 5.

[0041] The reflective sheet 2 and the transparent shell 5 are sealed around each other so that the potting glue will not leak out of the shell 1 during the subsequent potting process after the shell 1 is turned upside down.

[0042] S300: Install the controller, battery and road stud lights

[0043] The controller, the battery 42 and the road spike lamp 3 are installed into the cavity 11 of the housing 1 , and the lamp head of the road spike lamp 3 extends into the lamp post 21 of the reflector 2 .

[0044] S400: Circuit connection

[0045] The circuit connection parts of the road stud light 3, the controller, the solar panel 41 and the battery 42 are welded together.

[0046] S500: First time glue filling

[0047] After the circuit connection is completed, the housing 1 is turned upside down and the first glue pouring is performed. The pouring glue is epoxy glue. The pouring glue is injected into the pouring hole 13 and the lamp hole 14 from the cavity 11 of the housing 1, and the pouring glue flows into the reflector mounting groove 12 through the pouring hole 13 and the lamp hole 14 (mainly flows in through the pouring hole 13), so that the pouring glue fills the gap between the reflector 2 and the reflector mounting groove 12.

[0048] Before the first potting glue is cured, the reflector mounting groove 12 is thoroughly vented through the vent hole 15, that is, the gas between the reflector 2 and the reflector mounting groove 12 is exhausted. After the potting glue is cured, the sealing performance between the two can be further improved.

[0049] S600: Second glue filling

[0050] After the potting glue of the first potting is completely cured, the second potting can be performed, and the potting glue is injected into the cavity 11 of the housing 1 so that the cavity 11 is fully filled with the potting glue.

[0051] S700: Complete preparation

[0052] After the second potting glue is cured, the preparation of the entire externally embedded solar reflective road stud is completed.

[0053] An externally embedded solar reflective road stud and a manufacturing method thereof, wherein a through-hole for potting glue is provided between a cavity and a reflector mounting groove, and the diameter of the potting glue hole is larger than the lamp hole, so that more potting glue can be injected between the reflector and the reflector mounting groove during manufacturing. In this way, there is no extra gap between the reflector and the reflector mounting groove, and the two form a solid structure through the potting glue. Such a structure can ensure that the reflector has high-strength impact resistance and is not easily damaged under the impact of external forces. And because the reflector and the reflector mounting groove are in a solid structure, the pressure resistance and waterproof performance are more superior and durable.

[0054] The above contents are further detailed descriptions of the present application in combination with specific implementation methods, and it cannot be determined that the specific implementation of the present application is limited to these descriptions. For ordinary technicians in the technical field to which the present application belongs, several simple deductions or substitutions can be made without departing from the inventive concept of the present application.
