Description

Technical Field

[0001] The invention relates to the field of display front frames, and in particular to a vehicle-mounted display front frame with a shading function. Background Art

[0002] The front frame of the car display is the frame structure around the front of the car display. It has the following important functions: first, it provides physical protection for the screen and internal components of the display to prevent external impact, scratches and foreign object intrusion; second, it ensures that the display can be firmly installed in the designated position inside the vehicle and withstand vibrations and bumps during vehicle driving.

[0003] The front frame of the car display on the market is usually installed naked on the back of the vehicle seat to provide passengers with an entertainment experience in watching movies. However, the vehicle will be exposed to the sun when it is parked. Long-term exposure to the sun will cause the screen material of the display to age, resulting in color distortion and brightness reduction, affecting the display effect. Secondly, exposure to the sun will cause the temperature of the car display to rise, and high temperature will damage the electronic components inside the display, shorten its service life, and increase the probability of failure. At the same time, the outer shell of the front frame of the car display will be deformed due to high temperature, and the color will fade, affecting the appearance. Secondly, the display usually has a built-in battery, and high temperature will accelerate the aging of the built-in battery of the display, reducing the battery capacity and endurance. At the same time, exposure to the sun will cause the display material to become fragile and prone to cracking during subsequent use, posing a potential risk of injury to passengers.

[0004] The in-car display installed on the back of the vehicle seat can provide passengers with an entertainment experience in watching movies, but when the vehicle collides, the in-car display will break or fall off, and its sharp fragments or hard parts will cause secondary injuries such as scratches and punctures to the passengers. At the same time, the in-car displays on the market have no protection measures, and the fragments will fly in the car, causing unpredictable injuries to other passengers, increasing the overall safety risks.

[0005] Secondly, the car displays on the market are usually fixed to the back of the vehicle seat with ordinary nuts, and the vehicle will produce continuous vibration during driving. Ordinary nuts are prone to gradually loosen under the influence of long-term vibration. Once the nuts are loose, the display will shake or even fall off, posing a safety hazard to passengers. At the same time, it is necessary to check the tightness of the nuts regularly, which increases the manpower and time costs of maintenance. Ordinary nuts are prone to wear and corrosion under the influence of environmental factors such as frequent vibration and temperature changes, which reduces the durability of their fastening effect. At the same time, ordinary nuts cannot provide long-term stable fixing effects.

[0006] Therefore, it is necessary to provide a front frame of a vehicle-mounted display with a shading function to solve the above problems. Summary of the invention

[0014] Preferably, the shading plate is arranged below the dustproof rotating plate, and the strip-shaped sliding block and the distance-increasing plate are both slidably connected to the inside of the strip-shaped groove block.

[0015] Preferably, the sliding plate is slidably connected to the bottom of the cylindrical groove, and the elastic sheet is set to be T-shaped.

[0016] Preferably, an inductive control relationship is formed among the photoresistor, the electric hydraulic rod and the vehicle backup power supply.

[0017] Preferably, the control ring is electrically connected to the electromagnet block group, and the conductive ball is electrically connected to the vehicle power supply.

[0018] The present invention provides a front frame of a vehicle-mounted display with a shading function. Compared with the prior art, the present invention has the following beneficial effects:

[0019] 1. Through the setting of the automatic shading component, when the vehicle is parked, the photoresistor detects that the sunlight exceeds the temperature adapted to the vehicle display. The photoresistor will reduce its own resistance through the irradiation of strong light, thereby allowing the internal charge of the circuit formed by the photoresistor electric hydraulic rod to flow normally. Then the electric hydraulic rod drives the shading plate to rise through the distance extension plate and the bar slider. Then the shading plate blocks the sunlight irradiating the display, reducing the damage of the ultraviolet rays and high temperature in the sunlight to the display screen, shell and internal components, and extending the service life of the display. Secondly, it prevents the screen from aging, fading, uneven brightness and other problems due to exposure to the sun, ensuring that a good display effect can be maintained in subsequent use. Compared with the traditional device that requires manual operation to unfold or adjust the shading cloth, this device automatically blocks the display under strong light conditions without manual intervention, and is more convenient to use;

[0020] Secondly, because the sunshade is made of silicon, the sunshade can convert the light energy from the sun shining on the display into the electric energy used by the electric hydraulic rod. Compared with the traditional vehicle display sunshade device, it achieves the purpose of energy self-sufficiency and does not need to rely on the vehicle power supply. The traditional device may consume the vehicle battery power, while the new device relies on the electric energy converted by itself, can work independently and continuously, is not affected by the vehicle power supply status, reduces the dependence on the vehicle battery or external power supply, makes full use of the sunlight energy that would otherwise cause damage, reduces energy consumption, conforms to the concept of environmental protection, and in the long run reduces the need to replace batteries or maintain external power systems, reduces the cost of use and maintenance, reflects the intelligent integration of the system, and improves the overall performance and reliability of the equipment;

[0021] Among them, the shading plate will resist the surface of the display during the shading process, thereby minimizing the sunlight from the gap to the display, providing more comprehensive shading protection for the display, and at the same time providing certain physical support for the display, reducing the shaking and potential damage to the display caused by external factors (such as strong winds), and at the same time, it can block dust and moisture from entering the gap between the display and the shading plate to a certain extent, protecting the internal components of the display.

[0022] 2. Through the setting of the photoresistor, the photoresistor starts to operate when the vehicle is stationary. At the same time, the photoresistor can respond to strong light in real time and accurately. Compared with the traditional shading device, it avoids the delayed or inaccurate response of the traditional device. Secondly, the resistance value of the photoresistor will change according to the intensity of the sensed light. When the light intensity reaches a certain threshold, the resistance change of the photoresistor will trigger the change of the circuit state, thereby indirectly triggering the shading device to protect the vehicle display, provide timely and effective protection for the vehicle display, reduce the risk of failure or damage of the display due to high temperature and exposure, prevent the shell from deformation and fading, and keep the display in good appearance at all times.

[0023] Among them, the photoresistor will not trigger the shading device to block the vehicle display screen when the light is weak, avoiding the shading device not being triggered when the light is slightly weak, reducing unnecessary energy waste, and at the same time can reduce the wear of its mechanical parts and extend the service life of the shading device.

[0024] 3. Through the setting of the safety component, when a vehicle collides, the conductive ball will move due to inertia caused by the collision of the vehicle, thereby causing the conductive ball to break away from the restrictions of the arc limit block and the arc resistance rod, so that the conductive ball causes the control ring to cut off the power to the electromagnet block group through the conductive rod, and then the second reset spring elastically extends to push the elastic sheet up, so that the elastic sheet protects the display, thereby achieving instant protection of the display. At the same time, the inertia generated by the vehicle collision is used to trigger the protection mechanism, which has high accuracy and reliability, and avoids false triggering or delayed triggering. The rising elastic sheet can effectively block the fragments generated by the rupture of the display, reduce the risk of injury to passengers, and avoid the dangerous situation caused by the passenger's face hitting the display due to inertia when the vehicle collides.

[0025] 4. Through the setting of the anti-loosening component, the setting of the first tooth ring and the second tooth ring achieves that when the threaded nail is tightened, the friction force and wedging force generated by the wedge surfaces of the first tooth ring and the second tooth ring can prevent the threaded nail from loosening, thereby achieving the purpose of firmly fixing the display. At the same time, the contact surfaces of the threaded nail and the first tooth ring and the second tooth ring are designed with matching concave and convex structures to increase the contact area and friction, thereby achieving the anti-loosening effect. At the same time, the first tooth ring and the second tooth ring are composed of two kinds of threads, left-handed and right-handed. Under conditions of vibration, the loosening tendency of the threaded nail will be blocked by the thread of the other rotation direction, thereby achieving anti-loosening.

[0026] Secondly, due to the setting of the first gear ring and the second gear ring, it is ensured that the display always remains stable during the driving of the vehicle, especially in situations such as sudden braking, sharp turns or collisions, and will not fall or shake due to looseness, thereby reducing the risk of injury to passengers. At the same time, there is no need to frequently check and tighten the threaded nails, saving manpower, time and maintenance costs. Compared with traditional nuts, this structure can effectively maintain a tightened state for a long time and is not affected by factors such as vehicle vibration, temperature changes and humidity, extending the service life of the fixing device. At the same time, it ensures that the display can be firmly fixed under various complex driving conditions, reducing failures and damages caused by loose nuts. BRIEF DESCRIPTION OF THE DRAWINGS

[0044] The specific implementation of the present invention is described in detail below in conjunction with specific embodiments.

[0045] Implementation example Figures 1 to 11 As shown, a front frame of a vehicle-mounted display with a shading function is provided by an embodiment of the present invention. When in use, the front frame of a vehicle-mounted display with a shading function is installed inside a car seat 11 through a square positioning plate 12. A display 13 is installed on the car seat 11, and the display 13 is arranged inside the square positioning plate 12. An automatic shading component for automatically shading the display 13 is arranged inside the square positioning plate 12. The shading component is arranged inside the square positioning plate 12. A safety component for protecting the user when the vehicle collides is arranged inside the square positioning plate 12. An anti-loosening component for fixing the display 13 is arranged on the outside of the display 13.

[0046] The automatic shading assembly includes a dustproof rotating plate 21, which is rotatably connected to the bottom of the inner cavity of the square positioning plate 12, and the bottom of the square positioning plate 12 is slidably connected to a shading plate 22, and the outer wall of the shading plate 22 is symmetrically fixedly connected to a connecting block 23, and the interiors of the two connecting blocks 23 are both rotatably connected to a connecting rod 24, and the end of the connecting rod 24 away from the connecting block 23 is rotatably connected to a strip slider 25.

[0047] The automatic shading assembly also includes a distance-increasing plate 26, which is fixedly connected to one end of the strip slider 25 away from the connecting rod 24, and a strip groove block 27 is fixedly connected to one side of the connecting block 23 close to the square positioning plate 12. The bottom of the distance-increasing plate 26 is fixedly connected to an electric hydraulic rod 28, and the top of the square positioning plate 12 is fixedly connected to a photoresistor 29.

[0048] The safety component includes a cylindrical groove 31, which is opened at the top of the square positioning plate 12. A disc-shaped hollow block 32 is fixedly connected inside the cylindrical groove 31, an arc-shaped limit block 33 is fixedly connected to the top of the inner cavity of the disc-shaped hollow block 32, an arc-shaped resistance rod 34 is slidably connected to the bottom of the inner cavity of the disc-shaped hollow block 32, a sliding disk 36 is fixedly connected to the bottom of the arc-shaped resistance rod 34, a first return spring 35 is fixedly connected to the top of the sliding disk 36, and one end of the first return spring 35 away from the sliding disk 36 is fixedly connected to the bottom of the disc-shaped hollow block 32, a conductive rod 37 is fixedly connected to the inside of the disc-shaped hollow block 32 in an annular distribution, and a control ring 38 is fixedly connected to the end of the conductive rod 37 away from the disc-shaped hollow block 32, and a conductive ball 39 is arranged on the top of the conductive rod 37.

[0049] The safety component also includes a T-shaped groove 310, which is opened at the bottom of the square positioning plate 12. The inside of the T-shaped groove 310 is slidably connected to an elastic sheet 311, the bottom of the T-shaped groove 310 is fixedly connected to an electromagnet block group 312, the bottom of the elastic sheet 311 is fixedly connected to a second return spring 313, and the end of the second return spring 313 away from the elastic sheet 311 is fixedly connected to the bottom of the square positioning plate 12.

[0050] The anti-loosening assembly includes a threaded nail 41 , which is threadedly connected to the inside of the display 13 and the square positioning plate 12 , and the outer wall of the threaded nail 41 is sleeved with a first gear ring 42 and a second gear ring 43 .

[0051] The shading plate 22 is arranged below the dustproof rotating plate 21 to prevent dust from adhering to the surface of the shading plate 22. The strip slider 25 and the distance increasing plate 26 are both slidably connected to the inside of the strip groove block 27, so that the strip slider 25 and the distance increasing plate 26 can slide inside the strip groove block 27. The shading plate 22 is set to a silicon material, so that the shading plate 22 can use the light energy of the sunlight irradiating the display 13 to convert it into electrical energy used by the electric hydraulic rod 28. A torsion spring is arranged between the dustproof rotating plate 21 and the square positioning plate 12, so that when the shading plate 22 contacts the dustproof rotating plate 21, the dustproof rotating plate 21 can automatically reset.

[0052] The sliding plate 36 is slidably connected to the bottom of the cylindrical groove 31, and the shape of the elastic sheet 311 is set to be T-shaped, so that the elastic sheet 311 can slide inside the T-shaped groove 310. The material of the elastic sheet 311 is set to be Kevlar fiber, so that the elastic sheet 311 has high toughness and light weight, and the bottom of the elastic sheet 311 is set to be metal steel material, so that the electromagnet block group 312 can magnetically attract the elastic sheet 311.

[0053] An inductive control relationship is formed among the photoresistor 29, the electric hydraulic rod 28 and the vehicle backup power supply, so that the photoresistor 29 can energize and start the electric hydraulic rod 28, and the photoresistor 29 will not trigger the start of the electric hydraulic rod 28 when the vehicle is driving normally.

[0054] The control ring 38 is electrically connected to the electromagnet block group 312 , so that the control ring 38 can control the on and off of the electromagnet block group 312 . The conductive ball 39 is electrically connected to the vehicle power supply, so that the conductive ball 39 can energize the control ring 38 through the conductive rod 37 .

[0055] If the vehicle collides, the conductive ball 39 will move with the inertia generated by the collision of the vehicle, and then the conductive ball 39 will move away from the disc-shaped hollow block 32 due to inertia against the arc-shaped resistance rod 34, and then the arc-shaped resistance rod 34 will drive the sliding disk 36 to gradually stretch the first return spring 35. At this time, the conductive ball 39 that has escaped from the arc-shaped limit block 33 and the arc-shaped resistance rod 34 will slide along the inside of the disc-shaped hollow block 32, and then the conductive ball 39 will resist the conductive rod 37 inside the disc-shaped hollow block 32. Because there is an electrical connection between the conductive ball 39 and the vehicle power supply, the conductive ball 39 will then energize the control ring 38 through the conductive rod 37, and then the control ring 38 will control the electromagnet block group 312 to stop the magnetic attraction of the elastic sheet 311. At this time, the elastic sheet 311 will quickly protect the display 13 due to the second return spring 313.

[0056] Working principle: In the initial state, the shading plate 22 is located at the bottom of the square positioning plate 12, the strip slider 25 and the distance increasing plate 26 are both located at the bottom of the strip groove block 27, the arc limit block 33 and the arc contact rod 34 limit the position of the conductive ball 39, the first return spring 35 is not stretched, the second return spring 313 is compressed, and the conductive ball 39 does not contact the conductive rod 37.

[0057] During operation, when the vehicle is parked under the condition of being exposed to the sun, the vehicle is in a state of being turned off. Since the photoresistor 29, the electric hydraulic rod 28 and the vehicle backup power supply form an inductive control relationship, the vehicle backup power supply puts the photoresistor 29 in a working state. Since the photoresistor 29 is a light sensing element, its resistance value will change according to the intensity of the sensed light. When the light intensity reaches a certain threshold, the strong light will cause certain damage to the display 13. At this time, the resistance change of the photoresistor 29 will trigger a change in the circuit state. Subsequently, the internal resistance value of the photoresistor 29 is reduced due to the irradiation of the strong light. Finally, the photoresistor 29 connects the circuit between the electric hydraulic rod 28 and the vehicle backup power supply.

[0058] At this time, the electric hydraulic rod 28 is started, and then the electric hydraulic rod 28 drives the distance increasing plate 26 to rise. Because the strip slider 25 and the distance increasing plate 26 are both slidably connected to the inside of the strip groove block 27, the distance increasing plate 26 drives the strip slider 25 to rise horizontally along the inside of the strip groove block 27, and then the strip slider 25 drives the two connecting blocks 23 to rise through the connecting rod 24, and then the two connecting blocks 23 drive the shading plate 22 to first contact the dustproof rotating plate 21. At this time, the dustproof rotating plate 21 rotates along the bottom of the inner cavity of the square positioning plate 12 in the direction away from the shading plate 22. Because a torsion spring is provided between the dustproof rotating plate 21 and the square positioning plate 12, the dustproof rotating plate 21 always contacts the outer wall of the shading plate 22.

[0059] During the above movement, the connecting rod 24 drives the two connecting blocks 23 to rise, and then the connecting rod 24 and the top connecting block 23 contact the top of the inner cavity of the square positioning plate 12. At this time, the connecting rod 24 rotates around the strip slider 25 and the connecting block 23 at the same time, and the connecting rod 24 gradually becomes vertical with the shading plate 22, and the shading plate 22 gradually moves toward the display 13 due to the rotation of the connecting rod 24. When the strip slider 25 moves to the top of the strip groove block 27, the shading plate 22 contacts the display 13, thereby avoiding strong light from being exposed to the sun on the display 13 through the vehicle glass, extending the service life of the display 13, and secondly preventing the screen from aging, fading, uneven brightness, etc. due to exposure to the sun, and at the same time, it can prevent dust and moisture from entering the gap between the display 13 and the shading plate 22 to a certain extent, protecting the components inside the display 13;

[0060] Secondly, because the sunshade 22 is made of silicon, the sunshade 22 can convert the light energy of sunlight irradiating the display 13 into electrical energy used by the electric hydraulic rod 28, thereby achieving the purpose of energy self-sufficiency without relying on the vehicle power supply, making full use of the sunlight energy that would otherwise cause damage, reducing energy consumption, reflecting the intelligent integration of the system, and improving the overall performance and reliability of the equipment.

[0061] During the driving process of the vehicle, if the vehicle collides, the display 13 will break or fall off, and its sharp fragments or hard parts will cause secondary injuries such as scratches and stabs to the passengers. Therefore, after the vehicle collides, the conductive ball 39 will move with the inertia generated by the collision of the vehicle. At this time, the arc-shaped limit block 33 and the arc-shaped contact rod 34 limit the position of the conductive ball 39, and then the conductive ball 39 will contact the arc-shaped contact rod 34 when moving and move away from the disc-shaped hollow block 32. Then the arc-shaped contact rod 34 drives the sliding disk 36 to gradually stretch the first return spring 35. At this time, the conductive ball 39 that is free from the restriction of the arc-shaped limit block 33 and the arc-shaped contact rod 34 will slide along the inside of the disc-shaped hollow block 32, and then the conductive ball 39 will contact the conductive rod 37 inside the disc-shaped hollow block 32. Because there is an electrical connection between the conductive ball 39 and the vehicle power supply, the conductive ball 39 then causes the control ring 38 to be energized through the conductive rod 37.

[0062] Because there is an electrical connection between the control ring 38 and the electromagnet block group 312, the control ring 38 then cuts off the power to the electromagnet block group 312. At this time, the electromagnet block group 312 stops magnetically attracting the elastic sheet 311. Then the second return spring 313 breaks away from the pressure applied by the elastic sheet 311 and quickly stretches elastically. Then the second return spring 313 pushes the elastic sheet 311 to move toward the top of the square positioning plate 12. Because the shape of the elastic sheet 311 is set to be T-shaped, the elastic sheet 311 slides inside the T-shaped groove 310 at this time. Because the material of the elastic sheet 311 is set to Kevlar fiber, and the bottom of the elastic sheet 311 is set to be metal steel, the elastic sheet 311 can protect the display 13, avoiding the splashing of fragments caused by the rupture of the display 13, and reducing the risk of injury to the passengers. Due to the obstruction of the elastic sheet 311, when the passenger moves forward due to the impact of the vehicle, it will first hit the elastic sheet 311, avoiding the dangerous situation caused by the passenger's face hitting the display 13 due to inertia when the vehicle collides.

[0063] Because the display 13 on the market is usually fixed to the back of the car seat 11 by ordinary nuts, and ordinary nuts are prone to gradually loosen under the influence of long-term vibration, the setting of the first tooth ring 42 and the second tooth ring 43 can prevent the threaded nail 41 from loosening by the friction and wedging force generated by the wedge surfaces of the first tooth ring 42 and the second tooth ring 43 when the threaded nail 41 is tightened, thereby achieving the purpose of firmly fixing the display 13 and the square positioning plate 12. At the same time, the first tooth ring 42 and the second tooth ring 43 are composed of left-handed and right-handed threads. When vibration occurs during the driving of the vehicle, the loosening tendency of the threaded nail 41 will be prevented by the thread of the other rotation direction, thereby achieving anti-loosening, and achieving the situation that the display 13 always remains stable when the vehicle brakes suddenly, turns sharply or encounters a collision, and the threaded nail 41 will not fall or shake due to loosening.
