Description

Technical Field

[0001] This utility model belongs to the field of road safety equipment, and in particular relates to a 3D printed dark textured embossed luminous car stop ball. Background Technology

[0002] In urban construction, bollards and wheel stops are commonly used to separate vehicles from pedestrians, and are mostly made of stone or metal. Additionally, wheel stops often use reflective warning stickers at night to indicate their location, preventing collisions caused by drivers' poor visibility. However, when vehicles are reversing, passive reflective stickers often fail to provide sufficient illumination to alert drivers to the wheel stops, potentially leading to collisions and damage. Summary of the Invention

[0003] The problem this invention aims to solve is to overcome the shortcomings of the prior art and provide a 3D printed dark-textured embossed luminous car stop.

[0004] This invention is achieved through the following technical solution:

[0005] A 3D-printed, textured, embossed, illuminated bollard includes a base, a core column, and an outer shell. The outer shell covers the base and core column. The base includes a base plate, which is fixed to the ground by bolts. A lower connecting part is integrally formed on the base plate, into which a hollow core column is inserted. Light-emitting diodes (LEDs) are installed around the core column, and the upper part of the core column has external threads. A power supply is located inside the center of the base plate, and the power cord passes through the base plate and connects to the LEDs. The outer shell is a 3D-printed hollow spherical cavity. The bottom ends of both sides of the outer shell are base supports, with the bottom surfaces of the base supports flush with the bottom surface of the base plate. The outer shell includes an outer shell and an inner shell. A textured, embossed pattern is 3D-printed on the inner or outer surface of the outer shell. An opening is provided at the top of the outer shell, and a top cover is provided at the opening. An upper connecting part is fixed downwards at the center of the top of the inner shell. The inner surface of the upper connecting part has internal threads, and the upper connecting part is threadedly connected to the upper part of the core column. The base plate, lower connecting part, and upper connecting part are all made of vulcanized rubber.

[0006] Preferably, the core post is made of ABS plastic.

[0007] Preferably, the outer casing is made of ABS plastic.

[0008] The parking barrier of this invention has only its base fixed to the ground, while the outer shell is not fixed to the ground. In the event of a vehicle collision, it can move horizontally, buffering the impact force when the vehicle hits the parking barrier and reducing collision damage. At the same time, the internal core light source improves the nighttime visibility of the parking barrier, enhancing driving safety. The subtle embossed patterns inside the outer shell serve to remind and beautify the environment. The 3D-printed outer shell made of ABS material is sturdy and durable, replacing traditional stone or imitation stone parking barriers, saving stone resources, and is more environmentally friendly. Furthermore, the smooth surface of the ABS material parking barrier is easy to clean, reducing cleaning costs. Attached Figure Description

Detailed Implementation

[0015] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are some embodiments of the present invention, but not all embodiments.

[0016] This embodiment comprises three main parts: a base 1, a core column 2, and a housing 3. The base 1 includes a base plate 11, which is fixed to the ground by bolts 5. A lower connecting part 12 is integrally formed on the upper surface of the base plate 11, and in this embodiment, the lower connecting part 12 is cylindrical. Both the base plate 11 and the lower connecting part 12 are integrally made of vulcanized rubber. A hollow core column 2 is inserted into the lower connecting part 12. The core column 2 is made of ABS plastic, which is an abbreviation for Acrylonitrile Butadiene Styrene. ABS plastic is a terpolymer of acrylonitrile (A), butadiene (B), and styrene (S). The upper part of the core column 2 has external threads. Light-emitting diodes (LEDs) 7 are installed around the core column 2. The LEDs 7 are connected to a power source, a power source 6, which is installed inside the base plate 11. The power supply wire of the power source 6 passes through the base plate 11 and connects to the LEDs 7, supplying power to the LEDs 7 to emit light.

[0017] The outer shell 3 is a hollow spherical cavity printed in one step by a 3D printer. It can be made of ABS plastic. The outer shell 3 includes an outer shell 31, a textured relief 32, an inner shell 33, an upper connecting part 34, and a base 35. The base 35 is symmetrically located at the bottom of both sides of the outer shell 3, and the bottom surface of the base 35 is flush with the bottom surface of the base plate 11. The entire outer shell 3 covers the base 1 and the core column 2. The textured relief 32 is printed by a 3D printer on the inner or outer surface of the outer shell 31. In this embodiment, the textured relief 32 is printed on the inner surface of the outer shell 31, as shown in the attached figure. Figure 1 As shown, when the core pillar 2 is lit, less light passes through the dark relief 32 areas, creating shadows on the outer casing 3, thus displaying text, pictures, etc., as shown in the attached diagram. Figure 4 The embossed pattern 32 in the middle is a parking lot guidance pattern, and can also be used to 3D print advertisements and promotional content.

[0018] The outer casing 3 has an opening at its upper end, and a top cover 4 is provided at the opening. Water can be injected into the cavity of the outer casing 3 through the opening to increase the weight of the bollard and prevent it from shifting during daily use. After water is injected, the top cover 4 is closed to prevent water from evaporating.

[0019] An upper connecting part 34 is fixed downward at the top center of the inner shell 33. The upper connecting part 34 is also made of vulcanized rubber and is cylindrical. The inner surface of the upper connecting part 34 is provided with internal threads, and the upper connecting part 34 is threaded together with the upper part of the core column 2.

[0020] In this embodiment, the parking barrier is powered by the power supply 6 to emit light from the LED 7 at night. The light emitted by the LED 7 passes through the core post 2 and the outer shell 3, causing the parking barrier to illuminate. The dark relief 32 will display its graphics, improving the parking barrier's nighttime visibility and increasing the driver's awareness to avoid it. When a vehicle accidentally hits the parking barrier, the lower connecting part 12 of the base 1 and the upper connecting part 34 of the outer shell will both deform under force, causing the parking barrier outer shell 3 to shift laterally in the direction of impact, as shown in the attached figure. Figure 5 As shown, this reduces the reaction force of the ball stop on the vehicle, thereby reducing the impact force and protecting the driver, and reducing collision damage.

[0021] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and not to limit them; those skilled in the art should understand that modifications can still be made to the technical solutions described in the above embodiments, or equivalent substitutions can be made to some of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the various embodiments of the present invention.
