[0023] refer to Figure 1-4 The utility model provides a screen protection structure for a head-up display in an automobile. According to one embodiment, the structure provides flexible protection for the display screen, including a base 1 fixed to the vehicle body. A display screen 2 and a transparent cover 3 are provided on the base 1. The display screen 2 is the main display component of the electronic device and is located within the transparent cover. The displayed content is controlled by electrical signals. An airbag portion 4 is provided between the display screen 2 and the transparent cover 3 and is located around the display screen 2 for protecting the display screen 2. The airbag portion 4 is located around the display screen 2. The airbag portion 4 includes a back surface and two sides surrounding the display screen 2. The airbag portion 4 is not provided facing the front of the display screen 2. The transparent cover 3 of the display screen 2 is located around the display screen 2 and the airbag portion 4. The interior is filled with gas that can be quickly inflated when impacted. When the device falls, the airbag portion absorbs and disperses the impact force. A rotating hinge structure is provided between the lower edge of the transparent cover 3 and the base 1. The transparent cover 3 can be opened and closed by rotating the hinge structure, thereby protecting the display screen 2 and the transparent cover 3.

[0024] Commonly used materials for the transparent cover 3 include, but are not limited to, glass, tempered glass (such as Corning Gorilla Glass), polycarbonate (PC), polymethyl methacrylate (PMMA, commonly known as acrylic), and certain highly transparent composite materials, such as glass and plastic laminated together.

[0025] The provision of the airbag portion 4 can absorb the impact force when the device collides or falls, and at the same time, combined with the transparent cover 3, can buffer and disperse the impact force to a certain extent, thereby effectively protecting the display screen from damage.

[0026] In some specific embodiments, in order to enable the transparent cover 3 to be flipped open and closed, a rotating hinge structure is designed to include a rotating seat 11 and a mounting seat 12. The rotating seat 11 is connected to the transparent cover 3 and can be flipped open, while the mounting seat 12 is fixedly connected to the base 1. A rotating shaft 13 is connected between the rotating seat 11 and the mounting seat 12, which can enable the transparent cover 3 to rotate at a certain angle, thereby enabling the transparent cover 3 to be flipped open and closed.

[0027] In a further embodiment, the rotating seat 11 includes a first semicircular block 111, and the mounting seat 12 includes a second semicircular block 121. The first semicircular block 111 is connected to a first arc-shaped protruding block 112, and the second semicircular block 121 is connected to a second arc-shaped protruding block 122. The first arc-shaped protruding block 112 and the second arc-shaped protruding block 122 protrude in the same direction, which is vertically upward at the same time in this embodiment, just like arch bridges side by side, with a rotating shaft 13 passing through the bottom. The first arc-shaped protruding block 112, the second arc-shaped protruding block 122 and the rotating shaft 13 cooperate to make the transparent cover 3 rotate around the axis.

[0028] In a further embodiment, one or two first arc-shaped protruding blocks 112 are connected to the first semicircular block 111, and one or two second arc-shaped protruding blocks 122 are connected to the second semicircular block 121. The matching method is that the two second arc-shaped protruding blocks 122 are located at both ends, and one first arc-shaped protruding block 112 is located in the middle, or the two first arc-shaped protruding blocks 112 are located at both ends and one second arc-shaped protruding block 122 is located in the middle.

[0029] In a further embodiment, a rotation gap 131 is defined between the first arc-shaped protruding block 112 and the second arc-shaped protruding block 122 , so that the first arc-shaped protruding block 112 can rotate in the rotation gap 131 .

[0030] In some specific embodiments, because the display screen 2 is generally fixed on a horizontal plane close to the driver's line of sight, such as above the instrument panel or at a specific position on the inside of the front windshield, the utility model mainly considers setting the position of the base 1 above the instrument panel. The base is not specifically unfolded. A fixed shell 5 is provided on the base 1 between the display screen 2 and the transparent cover 3. The fixed shell 5 contains a cavity around it. The cavity is provided with an airbag part 4. When there is no gas, the airbag part 4 is located at the lower part of the cavity. The airbag part 4 includes an airbag bag 41. When inflated, the airbag bag 41 unfolds to surround and protect the display screen 2.

[0031] In a further embodiment, how the airbag bag 41 is fixed and able to be deployed, specifically, an air inlet limiting hole 51 and an air outlet limiting hole 52 are provided at the bottom of the fixed shell 5, and the airbag bag 41 is provided with an air pipe and an air inlet 411 passing through the air inlet limiting hole 51, and the airbag bag 41 is provided with an air pipe and an air outlet 412 passing through the air outlet limiting hole 52; the air inlet 411 and the air outlet 412 are extended parts of the airbag bag 41, which are connected by elastic deformation of the air pipe and are limited by passing through the air inlet limiting hole 51 and the air outlet limiting hole 52.

[0032] In a further embodiment, the airbag 41 is connected to the air intake pump 6 through the air pipe and the air inlet 411 and is connected to the air outlet pump 7 through the air pipe and the air outlet nozzle 132. The air intake pump 6 and the air outlet pump 7 are respectively provided with an air intake switching switch 61 and an air outlet switching switch 71 for controlling the airbag 41; the air intake switching switch 61 and the air outlet switching switch 71 are both provided with solenoid valves; an air pressure sensor 132 is provided inside the airbag 13, and the air pressure sensor 132 is connected to the control system in the vehicle body. The control system can control the opening and closing of the air intake switching switch 61 and the air outlet switching switch 71, so that the airbag 13 is closed when the inflation volume reaches a preset threshold and is opened when the preset threshold is not reached. On; the display screen 2 is a touch control screen, the human-computer interaction part; the touch control screen can display and control the status of the airbag 41, and the control system in the vehicle body is respectively connected to the display screen 2, the air intake switching switch 61, the air outlet switching switch 71 and the air pressure sensor 132. When air inlet and outlet are required, the control system uses the sensor, which is the air pressure sensor 132 in this embodiment, and its air pressure signal is transmitted to the receiving, storage, analysis and processing module of the control system in real time, and then the processing result is sent to the air intake switching switch 61 or the air outlet switching switch 71 through the solenoid valve according to the preset threshold to control the opening and closing of the air intake pump 6 and the air outlet pump 7, thereby realizing intelligent control of the airbag 41 and protecting the display screen 2 at all times.

[0033] In a further embodiment, in the height direction, the height of the airbag bag 41 is higher than the height of the display screen 2. For convenience, the airbag bag 41 is set as a straight line in the height direction. On the premise that the height of the airbag bag 41 is higher than the height of the display screen 2, the top of the airbag bag 41 is further designed to be slightly higher than the top of the display screen 2 and gradually narrows into an arc, which can better protect the display screen 2.
