Description

Technical Field

[0001] This utility model belongs to the field of locomotive headlight technology, specifically relating to a headlight glass assembly for locomotives. Background Technology

[0002] The headlight of a train locomotive is a lighting device installed at the head of a train locomotive. At night or in low light conditions, the headlight provides illumination of the track ahead, enabling the driver to clearly observe the track, signals, obstacles, etc., ensuring driving safety. The glass of the locomotive headlight is usually made of special glass materials, such as tempered glass, which has high strength and impact resistance, and can withstand various external impacts that the locomotive may encounter during operation, such as flying stones, to ensure the normal operation of the headlight.

[0003] As trains and high-speed trains increase their operating speed, locomotive headlights may be subjected to greater impact forces. Existing headlight glass and locomotives are usually bonded to the headlight housing using butyl sealant or high-performance adhesive, or fixed with screws or clips. When the locomotive headlight glass is impacted, it is easily damaged. Utility Model Content

[0004] In view of the problems mentioned in the background art, the purpose of this utility model is to provide a headlight glass assembly for locomotives to solve the problems mentioned in the background art.

[0005] To achieve the above-mentioned technical objectives, the technical solution adopted by this utility model is as follows:

[0006] A headlight glass assembly for locomotives includes tempered glass. A panel is mounted on the outer side of the tempered glass. The panel is annular and hollow in the center. The cross-section of the panel is convex. A mounting plate is connected to the convex side of the panel. The mounting plate is annular and hollow in the center. The annular edge of the mounting plate is aligned with the outer edge of the convex side of the panel. The outer ring of the tempered glass is located in a right-angled groove on the inner side of the convex side of the panel. Studs are mounted on the mounting plate and are evenly distributed along the annular line of the mounting plate. A first rubber pad is connected to the panel side away from the tempered glass.

[0007] Further defined, the tempered glass has two curved sides and the remaining two straight sides, and the shapes of the panel and mounting plate are coupled with the tempered glass.

[0008] Further specifying, three studs are assembled and connected to both sides of the straight mounting plate, and two studs are assembled and connected to both sides of the curved mounting plate.

[0009] Furthermore, a second rubber pad is provided between the panel and the locomotive, the second rubber pad and the outer edge of the panel are located on the same plane, and a gap is left between the inner edge of the second rubber pad and the panel.

[0010] Further specified, a third rubber pad is bonded between the panel and the mounting plate, and one side of the tempered glass is in contact with the third rubber pad.

[0011] Further specified, the panel has two chamfers on the side away from the tempered glass, and the two chamfers are located on the two side edges of the panel respectively.

[0012] Compared with the prior art, the present invention has the following advantages:

[0013] This utility model features a first rubber pad on one side of the panel.

[0014] The corners of the tempered glass in this invention are rounded, which effectively reduces the stress at the corners of the tempered glass and thus improves the stability of the tempered glass.

[0015] This invention is ingeniously designed. By leaving a gap between the third rubber pad and the protrusion of the panel, the rubber pad has room to deform, thus preventing the sides of the third rubber pad from being squeezed.

[0016] This utility model has a clever design. By setting a chamfer at the outer corner of the panel, the connection at the corner of the panel is smooth, which effectively reduces the stress concentration at the corner. At the same time, the edge of the panel has a smaller thickness while ensuring the strength of the panel.

[0017] This invention utilizes the cooperation of a second and a third rubber pad, so that when the panel is subjected to an external impact, the protrusion of the panel compresses the third rubber pad, while the second rubber pad on the outer side of the panel cushions the outer side of the panel, thereby preventing the panel from tilting and compressing the tempered glass at a single point, thus protecting the glass.

[0026] like Figure 1-3 As shown, a headlight glass assembly for a locomotive includes tempered glass 6. A panel 2 is mounted and connected to the outer side of the tempered glass 6. The panel 2 is annular and hollow in the middle. The cross-section of the panel 2 is convex. A mounting plate 1 is connected to the convex side of the panel 2. The mounting plate 1 is annular and hollow in the middle. The annular edge of the mounting plate 1 is aligned with the outer edge of the convex side of the panel 2. The outer ring of the tempered glass 6 is located in a right-angled groove on the inner side of the convex side of the panel 2. A stud 7 is mounted and connected to the mounting plate 1. The stud 7 is evenly arranged along the annular line of the mounting plate 1. A first rubber pad 3 is connected to the side of the panel 2 away from the tempered glass 6.

[0027] In this embodiment, panel 2 protects the edge of tempered glass 6. The outer platform of panel 2 is connected to the locomotive. The edge of tempered glass 6 is located in a right-angled groove on the inner side of panel 2. Mounting plate 1 connects to studs 7. One end of stud 7 is connected to mounting plate 1, and the other end is connected to the locomotive, thereby connecting the tempered glass to the locomotive. The locomotive has grooves at corresponding positions for mounting studs 7 and the first rubber pad 3, ensuring a tight connection between the device and the locomotive.

[0028] Reference Figure 1The tempered glass 6 has two curved sides and the remaining two straight sides. The shapes of the panel 2 and the mounting plate 1 are coupled with those of the tempered glass 6. In this embodiment, the corners of the tempered glass 6 are curved, which can effectively reduce the stress on the tempered glass 6. The panel 2 and the mounting plate 1 are assembled and connected to the edge of the tempered glass 6 to protect it.

[0029] Reference Figure 1 Three studs 7 are fitted and connected to the two side edges of the straight mounting plate 1, and two studs 7 are fitted and connected to the two side edges of the curved mounting plate 1. In this embodiment, the evenly distributed studs 7 can make the mounting plate 1 bear the force evenly, thereby avoiding deformation of the mounting plate 1 under force.

[0030] Reference Figure 2-3 A second rubber pad 4 is provided between the panel 2 and the locomotive. The second rubber pad 4 and the outer edge of the panel 2 are on the same plane, and a gap is left between the inner edge of the second rubber pad 4 and the panel 2. In this embodiment, the second rubber pad 4 is used to make the contact between the edge of the panel 2 and the locomotive a soft contact, so that when the outer side of the panel 2 is subjected to external impact, the second rubber pad 4 can play a buffering role.

[0031] Reference Figure 2-3 A third rubber pad 5 is bonded between panel 2 and mounting plate 1, and one side of tempered glass 6 contacts the third rubber pad 5. In this embodiment, the third rubber pad 5 is used to ensure a soft contact between panel 2 and mounting plate 1, while one side of tempered glass 6 contacts the third rubber pad 5. This allows the third rubber pad 5 to cushion the edge of tempered glass 6 when it is impacted. At the same time, when panel 2 is impacted by external force, the protrusions of panel 2 compress the third rubber pad 5, and the second rubber pad 4 on the outer side of panel 2 cushions the outer side of panel 3, thereby preventing the panel from tilting and causing single-point compression of the tempered glass.

[0032] Reference Figure 3 The panel 2 has two chamfers on the side away from the tempered glass 6, and the two chamfers are located on the two side edges of the panel 2. In this embodiment, the chamfers make the edges of the panel 2 connect with a smooth plane, reducing stress concentration in the panel 2.
