[0045] Please see Figure 1-9 This utility model provides a technical solution: a thick-walled optical guide signal device for non-motorized vehicles, including a boat-shaped bottom shell 1, a circuit board 2, an inner sleeve 3, two sets of retroreflectors 4, and a wire harness tube 5.

[0046] A bottom hole 11 is provided through the top of the boat-shaped bottom shell 1. An annular bottom block 12 is fixedly connected to the bottom of the boat-shaped bottom shell 1 near the bottom hole 11. Two sets of internally threaded base columns 13 are fixedly connected at intervals to the bottom of the boat-shaped bottom shell 1. Installation bolts 14 are inserted and connected through the threaded structure inside the bottom of the boat-shaped bottom shell 1. A sleeve 15 is integrally connected to the bottom of the boat-shaped bottom shell 1.

[0047] The circuit board 2 is connected to the inside of the boat-shaped bottom shell 1. Several sets of surface-mount LED beads 21 and two sets of built-in screws 22 are connected at equal intervals on the circuit board 2. The built-in screws 22 pass through the circuit board 2 and are connected to the inside of the internal thread base column 13 through the thread structure.

[0048] Specifically, the surface mount LED 21 is an RGB LED. When used as a taillight, all surface mount LEDs 21 are constantly red. When used as a brake, all surface mount LEDs 21 are bright red. When used for left or right turns, the surface mount LEDs 21 flash yellow on the left or yellow on the right.

[0049] The front and rear sides of the boat-shaped bottom shell 1 are recessed, and the width of the circuit board 2 is adapted to the width of the inner side of the middle of the boat-shaped bottom shell 1. Specifically, the recessed design of the boat-shaped bottom shell 1 and the adaptation of the width of the circuit board 2 enable the device to be better installed on non-motorized vehicles of different widths, improving the applicability of the product and ensuring the stability of the circuit board 2 during assembly.

[0050] A positioning protrusion 121 is integrally connected to the top of the annular base block 12. A lead wire notch 23 is provided through the inner side of the circuit board 2. The positioning protrusion 121 is connected to the lead wire notch 23, and the width of the positioning protrusion 121 is adapted to the width of the lead wire notch 23. Specifically, the height of the positioning protrusion 121 is less than the height of the lead wire notch 23, so that after the circuit board 2 is assembled, the positioning protrusion 121 is located inside the lead wire notch 23. The design of the positioning protrusion 121 and the lead wire notch 23 ensures the accurate positioning of the circuit board 2 during the installation process, thereby improving the assembly efficiency and reliability of the device. In addition, the lead wire notch 23 can be used for wire threading, avoiding the problem of internal wire tangling.

[0051] The height of the internally threaded base post 13 is matched with the height of the head of the mounting bolt 14, and the internally threaded base post 13 and the head of the mounting bolt 14 are suitable for supporting the circuit board 2. Specifically, the mounting bolt 14 can be used to fix the boat-shaped bottom shell 1 and the device as a whole to the mounting location of the non-motorized vehicle. The matching height of the internally threaded base post 13 and the mounting bolt 14 ensures that after the circuit board 2 is fixed inside the boat-shaped bottom shell 1 by the built-in screw 22, the bottom of the circuit board 2 is in contact with the internally threaded base post 13 and the head of the mounting bolt 14, thereby ensuring the stability of the circuit board 2 during assembly and use and reducing damage caused by vibration or impact.

[0052] The inner sleeve 3 is connected to the top of the ship-shaped bottom shell 1. A lens module 33 is integrally connected to the top of the inner sleeve 3. Two sets of embedded areas 34 are formed by mirroring the lens module 33 on the top of the inner sleeve 3. Specifically, the addition of the lens module 33 effectively concentrates and disperses light, improves the coverage and intensity of the light signal, and thus enhances the warning effect of the signal.

[0053] Two sets of reflectors 4 are connected to the top of the inner sleeve 3.

[0054] The inner wall of the retroreflector 4 is composed of several sets of microprism structures. Specifically, the retroreflector 4 is made of a light-transmitting material. Through the setting of the microprisms, when the retroreflector 4 is illuminated by other light sources, the microprisms can act as passive light sources, that is, they function as reflectors. The design of the microprisms in the retroreflector 4 can effectively reflect the light from behind back, serving to remind the driver and increasing the visibility angle of the warning light, thereby improving the warning effect.

[0055] The bottom edge of the inner sleeve 3 is integrally connected to the lower outer edge 31, and the top edge of the inner sleeve 3 is integrally connected to the upper outer edge 32. The top of the boat-shaped bottom shell 1 is adapted to the inner side of the lower outer edge 31, and the two sets of retroreflectors 4 are adapted to the two sets of embedded areas 34 respectively. Specifically, the design of the upper and lower outer edges of the inner sleeve 3, which are adapted to the boat-shaped bottom shell 1 and the retroreflectors 4, enhances the sealing and weather resistance of the entire device, protects the internal components from the influence of the external environment, and allows the lens module 33 to be located on the outside of the entire device.

[0056] The wire harness tube 5 is connected to the sleeve 15.

[0057] The wire harness tube 5 includes an upper limit section 51 and a lower lead section 52, which are integrally connected, wherein:

[0058] The upper limit part 51 is connected to the inner side of the annular bottom block 12, and the outer diameter length of the upper limit part 51 is adapted to the inner diameter length of the annular bottom block 12.

[0059] The lower lead 52 is inserted and connected to the inside of the sleeve 15 with a clearance fit.

[0060] Specifically, the annular base block 12 is connected to the inner side of the sleeve 15 through the bottom hole 11. The outer diameter of the upper limit part 51 is greater than the outer diameter of the lower lead part 52. The sleeve 15 has a limiting effect on the upper limit part 51. During assembly, the bottom of the circuit board 2 also has a limiting effect on the upper limit part 51, that is, the upper limit part 51 is clamped and fixed inside the annular base block 12, thereby realizing the fixation of the wire harness tube 5, thus ensuring the fixation and protection of the wire harness. At the same time, it simplifies the guiding and installation process of the wire harness. The wire harness can be connected to an external power source, such as the battery power supply of an electric vehicle.

[0061] The lens module 33 includes several groups of square lenses arranged in a regular circular array. Specifically, this improves the focusing and dispersion capabilities of the light signal, making the light signal more concentrated and brighter, thus enhancing the warning effect and visual impact.

[0062] Specifically, the components can be fixed together using ultrasonic welding.

[0063] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
