[0004] The car lampshade of the above-mentioned patent is generally made of polycarbonate as raw material. Although this material has good strength, it is very easy to break if it is hit by an impact force exceeding the tolerance range. Some of the broken fragments will enter the car lampshade, causing damage to the bulb inside the car lampshade, resulting in increased maintenance costs. Summary of the Invention

[0005] The main technical problem solved by the present invention is to provide a high-strength automobile lampshade shell which can effectively protect the bulb from being damaged after the lampshade is hit.

[0006] In order to solve the above technical problems, the technical solution adopted by the utility model is: a high-strength automobile lampshade shell, including a mounting base and an outer shell, the material of the outer shell is polycarbonate, the inner wall of the outer shell is provided with a mesh PC board, and the mesh PC board is provided with a PVC film on the side away from the polycarbonate outer shell; a first connecting plate is provided on the outer shell, and a second connecting plate is provided between the outer shell and the mounting base, the second connecting plate includes an annular plate, a mounting plate arranged outside the annular plate, a connecting rod arranged between the annular plates, and a limiting hole provided on the connecting rod.

[0007] Furthermore, at least two slots are provided on the annular plate, at least two buckles are provided on the mounting base, and limiting blocks are provided on the buckles, and the slots and the buckles are connected in a one-to-one limiting manner.

[0008] Furthermore, a bulb mounting seat is provided on a surface of the mounting base close to the housing, and the position of the bulb mounting seat corresponds to the position of the limiting hole.

[0009] Furthermore, a cable tube is provided on a surface of the mounting base away from the housing.

[0010] Furthermore, a reflector is provided on the bulb mounting base.

[0011] Furthermore, the annular plate, the mounting plate, the connecting rod and the limiting hole are integrally arranged.

[0021] The following is a clear and complete description of the technical solution of the present invention in conjunction with the accompanying drawings. Obviously, the embodiments described are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative efforts are within the scope of protection of the present invention.

[0022] Please refer to Figures 1 to 4 , the utility model includes:

[0023] A high-strength automotive lampshade housing includes a mounting base 10 and an outer shell 1. The outer shell 1 is made of polycarbonate, and a mesh PC board 2 is provided on the inner wall of the outer shell 1. The mesh PC board 2 is provided with a PVC film 3 on the side away from the polycarbonate outer shell 1; a first connecting plate 4 is provided on the outer shell 1, and a second connecting plate is provided between the outer shell 1 and the mounting base 10. The second connecting plate includes an annular plate 5, a mounting plate 6 arranged outside the annular plate 5, a connecting rod 7 arranged between the annular plates 5, and a limiting hole 8 provided on the connecting rod 7. In this embodiment, the mounting base 10 is circular and is mounted on the annular plate 5. There are two first connecting plates 4, which are respectively mounted on the opposite outer sides of the shell 1. There are also two mounting plates 6. The first connecting plates 4 on the shell 1 are mounted on the mounting plates 6, thereby completing the installation of the lampshade; the shell 1 made of polycarbonate has high impact strength, and the shape of the shell 1 is a hollow hemisphere. A PVC film 3 is provided on the inner wall of the shell 1, and a layer of mesh PC board 2 is attached between the shell 1 and the PVC film 3. When the lampshade is impacted by external force, the shell 1 will bear most of the force. When the impact force exceeds the bearing range of the shell 1, the shell 1 will cause it to shatter. At this time, the mesh PC board 2 can intercept some larger fragments, and the remaining fragments are intercepted by the PVC film 3. Because the PVC film 3 has good ductility, the impact force of the remaining flying fragments is also alleviated after the action of the PVC film 3, preventing the fragments from damaging the bulb due to excessive impact force.

[0024] More specifically, at least two slots 9 are provided on the annular plate 5, at least two buckles 11 are provided on the mounting base 10, and stoppers are provided on the buckles 11. The slots 9 and the buckles 11 are connected in a one-to-one, position-limiting manner. In this embodiment, the slots 9 serve both positioning and position-limiting functions. The mounting base 10 is secured to the second connecting plate through the engagement of the buckles 11 with the slots 9. Simultaneously, the stoppers penetrate the slots 9 and engage the annular plate 5, preventing the mounting base 10 from falling off. Here, installation of the mounting base 10 is accomplished by simply aligning the buckles 11 with the slots 9 and then directly inserting them. The buckles 11 and the slots 9 can match each other, and during installation, all the buckles 11 are inserted into the slots 9 to complete installation of the mounting base 10.

[0025] More specifically, a bulb mount 12 is provided on the side of the mounting base 10 proximate to the housing 1. This mount 12 corresponds to the position of the retaining hole 8. In this embodiment, the bulb mount 12 is mounted in the center of the mounting base 10, and the retaining hole 8 is mounted in the center of the annular plate 5. The retaining hole 8 serves both positioning and limiting functions. During bulb installation, the bulb's mounting end must pass through the retaining hole 8 before being installed in the mounting base 10. If the clip 11 and the retaining slot 9 become detached due to other factors, the retaining hole 8 can prevent the housing 1 from falling.

[0026] More specifically, a cable tube 13 is provided on the side of the mounting base 10 away from the housing 1. In this embodiment, the cable tube 13 can pull the cable at the rear end of the bulb mounting base 12 out to connect to the power supply. At the same time, the cable tube 13 is provided with a thread inside, and the lampshade can be installed on the car through the cable tube 13.

[0027] More specifically, a reflector 14 is provided on the bulb mount 12. In this embodiment, the reflector 14 completely covers the bulb mount 12 and can reflect light onto the housing 1. At the same time, the mounting surface of the bulb mount 12 is also covered with the reflector 14, which can reflect light onto the housing 1, making the lampshade brighter during operation.

[0028] More specifically, the annular plate 5, mounting plate 6, connecting rod 7, and limiting hole 8 are integrally formed; the bulb mount 12 is integrally formed with the mounting base 10. In this embodiment, the second connecting plate is integrally formed using a casting process and then finely machined by turning and milling. Similarly, the bulb mount 12 and mounting base 10 are also manufactured using the same processing method.

[0029] More specifically, there are ten slots 9 and ten buckles 11. The slots 9 are evenly distributed on the annular plate 5 with the limiting hole 8 as the center, and the buckles 11 are evenly distributed on the mounting base 10 with the bulb mounting base as the center. In this embodiment, the more slots 9 and buckles 11 there are, the more stable the second connecting plate is on the mounting base 10. The number of slots 9 and buckles 11 is ten, and the limiting effect of the multiple slots 9 and buckles 11 can prevent the lampshade from falling off during operation due to some of the buckles 11 falling off, which could cause the housing 1 and the second connecting plate to fall off, thereby causing the housing 1 to fall off.

[0030] The specific installation process of the present invention is as follows: first, install the mounting base 10 on the vehicle body through the cable tube 13, then align the card groove 9 on the annular plate 5 with the buckle 11 on the mounting base 10, install the annular plate 5 on the mounting base 10, and then install the bulb mounting end on the bulb mounting seat 12 through the limiting hole 8. Finally, fix the first connecting plate 4 on both sides of the shell 1 and the mounting plates 6 on both sides of the annular plate 5 with fixing bolts to complete the installation of the entire lampshade.

[0031] To sum up, the working principle of the present invention is as follows: a PVC film 3 is provided on the inner wall of a polycarbonate shell 1, and a layer of mesh PC board 2 is attached between the shell 1 and the PVC film 3. When the lampshade is impacted by external force, the polycarbonate shell 1 will bear most of the force. If the impact force is large and causes the polycarbonate shell 1 to break, the mesh PC board 2 will block some larger fragments, and the remaining fragments will be blocked by the PVC film 3. In addition, because the PVC film 3 is stretchable, it can reduce the force of the flying fragments and prevent the bulb from being damaged.
