Description

Technical Field

[0001] The utility model relates to the technical field of fiberglass face shields for subway front end vehicles, in particular to a fiberglass face shield for subway front end vehicles. Background Art

[0002] As we all know, the subway is a high-capacity, highly efficient urban rail transit system, typically consisting of multiple lines. Using electric trains laid on underground or surface tracks, it transports large numbers of passengers quickly and punctually within a predetermined timeframe, alleviating urban traffic pressure and meeting citizens' travel needs. With independent operating tracks and station facilities, the subway system provides all-weather, high-frequency service and is a vital component of modern urban public transportation. A face shield is typically required on the front of the subway train, providing important protection against various external forces that may be encountered during operation.

[0003] However, traditional subway front-end covers are usually made of hard materials such as fiberglass or metal. These materials are not easy to deform when impacted, so it is difficult to effectively absorb the impact energy, which in turn causes the impact force to be directly transmitted to the vehicle structure. Therefore, technical improvements are urgently needed. Utility Model Content

[0004] The purpose of the utility model is to solve the shortcomings of the prior art and to propose a fiberglass mask for the front end of a subway train. When the fiberglass mask for the front end of a subway train is in use, the fiberglass bottom frame adopts fiberglass with high strength and rigidity, can withstand external impacts, and provide solid support for the entire mask. The design of the buffer groove and the buffer ring pad can provide additional buffer space when impacted, absorb more impact energy, and reduce damage to the overall structure of the mask.

[0005] To achieve the above objectives, the present invention provides the following technical solutions:

[0006] A fiberglass mask for the front end of a subway car comprises a bottom frame, a mounting groove is provided in the middle of the front end outer wall of the bottom frame, the bottom frame is made of fiberglass, the inner walls of the mounting groove are provided with outer glass, interlayer and inner glass from front to back, the surface of the outer glass is coated with a polyurethane coating, a buffer groove is provided in the middle of the inner wall of the mounting groove, a buffer ring gasket is provided on the inner wall of the buffer groove, and the inner wall of the buffer ring gasket is fixedly connected to both sides of the outer wall of the outer glass.

[0007] Through the above technical solution, compared with the existing fiberglass mask of the front end of the subway, the fiberglass mask of the front end of the subway can provide better protection by adopting a multi-layer structure. Even if the outer glass is damaged, the inner glass and the interlayer can still provide protection. The polyurethane coating can improve the impact resistance of the glass, making the outer glass less likely to break when impacted, and has higher practical performance.

[0008] Furthermore, a guide cone is fixedly connected to the lower portion of the front end outer wall of the bottom frame;

[0009] Through the above technical solution, the airflow can be effectively guided by the guide cone, so that the air can flow more smoothly through the front part of the vehicle and reduce air resistance.

[0010] Furthermore, the outer glass and the inner glass are respectively made of tempered glass and low-emissivity glass;

[0011] Through the above technical solution, the tempered glass has higher strength and impact resistance, and the low-emissivity glass has a certain blocking effect on ultraviolet rays, which can reduce the aging and fading effects of ultraviolet rays on the internal equipment and decorative materials of the front of the vehicle, and extend the service life of the equipment.

[0012] Furthermore, the interlayer adopts an ionic intermediate membrane;

[0013] Through the above technical solution, the ionic interlayer has excellent bonding properties, which can firmly bond glass fragments together when the glass is broken by impact, preventing the fragments from flying and injuring people.

[0014] The utility model has the following beneficial effects:

[0015] 1. The utility model proposes a fiberglass mask for the front end of a subway train. Compared with the existing fiberglass mask for the front end of a subway train, the fiberglass mask for the front end of a subway train has high strength and rigidity when used due to the fiberglass used in the bottom frame, and can withstand external impacts, providing solid support for the entire mask. The design of the buffer groove and the buffer ring pad can provide additional buffer space when impacted, absorb more impact energy, and reduce damage to the overall structure of the mask.

[0016] 2. The utility model proposes a fiberglass mask for the front end of a subway car. Compared with the existing fiberglass mask for the front end of a subway car, the fiberglass mask for the front end of a subway car can provide better protection when used by adopting a multi-layer structure. Even if the outer glass is damaged, the inner glass and the interlayer can still provide protection. The polyurethane coating can improve the impact resistance of the glass, making the outer glass less likely to break when impacted, and has higher practical performance.

[0023] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0024] Reference Figure 1-4 The utility model provides an embodiment: a fiberglass mask for the front end of a subway car, comprising a bottom frame 1, a mounting groove 11 being provided in the middle of the front end outer wall of the bottom frame 1, the bottom frame 1 being made of fiberglass, and the inner wall of the mounting groove 11 being provided with an outer layer of glass 2, an interlayer 4 and an inner layer of glass 3 from front to back, respectively, and the surface of the outer layer of glass 2 being coated with a polyurethane coating.

[0025] Compared with the existing fiberglass mask of the front end of the subway, the fiberglass mask of the front end of the subway can provide better protection by adopting a multi-layer structure. Even if the outer glass 2 is damaged, the inner glass 3 and the interlayer 4 can still provide protection. The polyurethane coating can improve the impact resistance of the glass, making the outer glass 2 not easy to break when impacted, and the practical performance is higher.

[0026] A guide cone 12 is fixedly connected to the lower part of the outer wall of the front end of the bottom frame 1. The guide cone 12 can effectively guide the airflow, so that the air can flow more smoothly through the front part of the vehicle, reducing air resistance. A buffer groove 13 is opened in the middle of the inner wall of the mounting groove 11, and a buffer ring pad 14 is provided on the inner wall of the buffer groove 13. The inner wall of the buffer ring pad 14 is fixedly connected to the two sides of the outer wall of the outer glass 2. When the front mask is hit or impacted, the buffer ring pad 14 can first absorb and disperse part of the energy, reducing the impact force directly transmitted to the glass and the bottom frame 1. The outer glass 2 and the inner glass 3 are respectively made of tempered glass and low-emissivity glass. The tempered glass has higher strength and impact resistance. The low-emissivity glass has a certain blocking effect on ultraviolet rays, which can reduce the aging and fading effects of ultraviolet rays on the internal equipment and decorative materials of the front of the vehicle, and extend the service life of the equipment. The interlayer 4 adopts an ionic intermediate membrane, which has excellent bonding properties. When the glass is broken by impact, the glass fragments can be firmly bonded together to prevent the fragments from flying and injuring people.

[0027] Working principle: When in use, the bottom frame 1 is made of fiberglass with high strength and rigidity, which can withstand external impact and provide solid support for the entire mask. The design of the buffer groove 13 and the buffer ring pad 14 can provide additional buffer space when impacted, absorb more impact energy, and reduce damage to the overall structure of the mask. The multi-layer structure can provide better protection. Even if the outer glass 2 is damaged, the inner glass 3 and the interlayer 4 can still provide protection. The polyurethane coating can improve the impact resistance of the glass, making the outer glass 2 not easy to break when impacted.

[0028] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
