Description

Technical Field

[0001] This utility model relates to the field of helmets, and more particularly to a helmet with a display function. Background Technology

[0002] A helmet with a display function is a product that combines display technology with helmet equipment. It can display various information or images in front of the user. When the user wears the helmet, a specific image can be projected onto the helmet's windshield using a light source and waveguide glass, thus providing prompts to the user.

[0003] In existing technologies, light sources are typically fixed directly to the sides of the helmet. To ensure that the light propagation path is not obstructed, the light source is usually made to protrude. When the windshield is closed, it can protect the light source. However, when the user opens the windshield, the light source protruding from the helmet is easily damaged by impact. Therefore, a helmet with a display function is proposed to solve the above problems. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a helmet with a display function, which aims to improve the problem in the prior art that "in order to ensure that the light propagation path is not obstructed, the light source needs to be set in a position protruding from the helmet body, so that the light source is easily damaged by collision."

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a helmet with a display function, comprising a helmet body, an inner liner fixedly connected to the inner wall of the helmet body, a rotating shaft rotatably connected to both the left and right ends of the helmet body, a windshield fixedly connected to the end of the rotating shaft away from the helmet body, an optical waveguide glass installed on the side of the windshield close to the helmet body, a movable component provided on the outer wall of the inner wall of the helmet body near the rotating shaft, and a light emitter slidably connected to the outer wall of the inner liner near the front of the rotating shaft;

[0006] The movable component includes a sliding frame, which is fixedly connected to the inner wall of the helmet body. The rotating shaft passes through and is rotatably connected to the inner wall of the sliding frame. The light emitter passes through and is slidably connected to the inner wall of the sliding frame. A slider is slidably connected to one end of the sliding frame near the inner liner. A connecting rod is fixedly connected to the upper surface of the slider. A cylindrical block is fixedly connected to the lower surface of the connecting rod. The upper surface of the light emitter is provided with inclined grooves, and the cylindrical block slides on the inner wall of the inclined grooves.

[0007] As a further description of the above technical solution:

[0008] A support rod is fixedly connected to the outer wall of the rotating shaft, and a hinge rod is hinged to the inner wall of the support rod. The other end of the hinge rod is hinged to the inner wall of the slider.

[0009] As a further description of the above technical solution:

[0010] The connecting rod and cylindrical block are provided in multiple sets, and the multiple sets of connecting rod and cylindrical block are symmetrically arranged with the center line of the slider as the axis of symmetry.

[0011] As a further description of the above technical solution:

[0012] A gasket is fixedly connected to the end of the light emitter away from the inner liner, and the end of the gasket away from the inner liner is set in an arc shape.

[0013] As a further description of the above technical solution:

[0014] The rotating shaft and the sliding frame are interference-fitted.

[0015] As a further description of the above technical solution:

[0016] An exhaust vent is provided on the front surface of the helmet near the bottom of the windshield.

[0017] As a further description of the above technical solution:

[0018] The front surface of the inner liner is provided with a second vent hole, which is connected to the first vent hole.

[0019] This utility model has the following beneficial effects:

[0020] 1. In this utility model, by adopting a sliding connection, when the projected image is not needed, the light emitter can be pushed into the helmet body. The light emitter moves inward and will be locked into the inner liner. In this way, the inner liner can protect the light emitter and prevent it from protruding from the helmet body, thus reducing the probability of damage.

[0021] 2. In this utility model, by setting a support rod, when the operator opens the wind deflector, the rotating shaft will drive the support rod to rotate, and the support rod will pull the slider to move backward through the hinge rod. The slider moving backward will drive the cylindrical block to squeeze the inclined groove, thus driving the light emitter to be retracted into the helmet body. This can achieve automatic extension and retraction, which is more convenient to use. Attached Figure Description

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] Reference Figure 1 , Figure 3 and Figure 4 This utility model provides an embodiment of a helmet with a display function, including a helmet body 1 for supporting the overall device. An inner liner 4 for wrapping the user's head is fixedly connected to the inner wall of the helmet body 1. Rotating shafts 8 for supporting wind deflectors 2 are rotatably connected to both ends of the helmet body 1. A wind deflector 2 for blocking oncoming wind is fixedly connected to the end of the rotating shaft 8 away from the helmet body 1. The wind deflector 2 can close the front opening of the helmet body 1, thus preventing foreign objects from entering the helmet body 1 through the front opening. A light waveguide glass 3 for displaying images is installed on the side of the wind deflector 2 near the helmet body 1. A moving component 7 for moving a light emitter 5 is provided on the outer wall of the inner wall of the helmet body 1 near the rotating shaft 8. A light emitter 5 is slidably connected to the outer wall of the inner liner 4 near the front of the rotating shaft 8. The light emitter 5 used in this application is a MicroOLED light source, which can provide high-resolution, high-contrast, and fast-response images. The light emitted by the light emitter 5 can form an image for the user to view by contacting the light waveguide glass 3.

[0030] Reference Figures 2-3The moving component 7 includes a sliding frame 71 for supporting the entire moving component 7. The sliding frame 71 is fixedly connected to the inner wall of the helmet body 1. A rotating shaft 8 passes through and is rotatably connected to the inner wall of the sliding frame 71. A light emitter 5 passes through and is slidably connected to the inner wall of the sliding frame 71. The light emitter 5 can slide left and right along the inner wall of the sliding frame 71. By using the sliding frame 71 to guide the light emitter 5, the stability of the light emitter 5 during movement can be ensured. A slider 72 for driving the connecting rod 75 is slidably connected to one end of the sliding frame 71 near the inner liner 4. The upper surface of the light emitter 5 is fixedly connected to a connecting rod 75 for supporting a cylindrical block 76. The lower surface of the connecting rod 75 is fixedly connected to a cylindrical block 76. The upper surface of the light emitter 5 is provided with inclined grooves 77 for accommodating the cylindrical block 76. The cylindrical block 76 slides on the inner wall of the inclined groove 77. When the slider 72 moves back and forth, it will drive the connecting rod 75 to move synchronously. The back and forth movement of the connecting rod 75 will squeeze the inclined groove 77 through the cylindrical block 76, thus driving the light emitter 5 to move left and right. At the same time, the inclined groove 77 and the cylindrical block 76 can limit the movement range of the light emitter 5.

[0031] Reference Figures 2-3 The outer wall of the rotating shaft 8 is fixedly connected to a support rod 73 for supporting the hinge rod 74. The inner wall of the support rod 73 is hinged to the hinge rod 74. The other end of the hinge rod 74 is hinged to the inner wall of the slider 72. When the operator closes the baffle plate 2, the rotating shaft 8 will rotate forward, thus pushing the slider 72 through the hinge rod 74, causing the slider 72 to move forward. The forward movement of the slider 72 will cause the cylindrical block 76 to squeeze the inclined groove 77, causing the light emitter 5 to move outward and be exposed. There are multiple sets of connecting rods 75 and cylindrical blocks 76. The multiple sets of connecting rods 75 and cylindrical blocks 76 are symmetrically arranged with the center line of the slider 72 as the axis of symmetry. When the slider 72 moves back and forth, the multiple sets of cylindrical blocks 76 will work together on the light emitter 5, thus improving the stability of the extrusion.

[0032] Reference Figures 2-3 A gasket 6 is fixedly connected to the end of the light emitter 5 away from the inner liner 4. When the light emitter 5 is at its outermost position, the gasket 6 will press against the inner wall of the windshield 2, thus preventing the end of the light emitter 5 from shaking randomly. The end of the gasket 6 away from the inner liner 4 is set to be arc-shaped. When the light emitter 5 is at its innermost position, the arc-shaped surface of the gasket 6 will fit against the outer wall of the helmet body 1. The pivot 8 and the sliding frame 71 are interference fit, thus preventing the pivot 8 from rotating randomly. An exhaust hole 11 is provided on the lower part of the front surface of the helmet body 1 near the windshield 2. An exhaust hole 41 is provided on the front surface of the inner liner 4. The exhaust hole 41 and the exhaust hole 11 are interconnected. By setting the exhaust hole 11 and the exhaust hole 41, the air exhaled by the user's mouth can be vented to the outside of the helmet body 1.

[0033] Working principle: When the operator manually closes the wind deflector 2, the wind deflector 2 will drive the rotating shaft 8 to rotate synchronously. The support rod 73 on the outer wall of the rotating shaft 8 swings forward with the rotation, and pushes the slider 72 along the sliding frame 71 forward through the hinge rod 74. The slider 72 drives the cylindrical block 76 to press the inclined groove 77 on the light emitter 5 forward through the connecting rod 75. The pressing pushes the light emitter 5 outward to the outside of the helmet body 1. The pad 6 at the end of the light emitter 5 will press the inner wall of the wind deflector 2, so as to fix the position and prevent shaking. At this time, the light source is aligned with the optical waveguide glass 3 and the image projection begins.

[0034] When the device is working normally, the light emitter 5 generates image light through the self-illumination of organic materials after being powered on. The light is projected onto the optical waveguide glass 3 inside the windshield 2, and guided to the front of the user's field of vision through optical waveguide technology to form a virtual image.

[0035] When the operator opens the wind deflector 2, the wind deflector 2 rotates backward, the rotating shaft 8 rotates in the opposite direction, the support rod 73 pulls the slider 72 backward through the hinge rod 74, the cylindrical block 76 presses against the inner wall of the inclined groove 77 in the opposite direction, and the light emitter 5 is pulled back into the helmet body 1 by the sliding frame 71 to avoid exposure and collision damage.

[0036] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model 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 utility model should be included within the protection scope of the present utility model.
