Description

Technical Field

[0001] The present invention relates to the technical field of display devices, and more specifically, to a TFT-LCD display module and a bonding process thereof. Background Art

[0002] With the development of digital technology, display technology is also constantly developing and the demand is increasing day by day. In the early days, cathode ray tubes (CRTs) had excellent display quality and technological maturity, so they monopolized the display market for many years. However, with the rise of the concept of green environmental protection in recent years, cathode ray tubes cannot meet the market development trend of light, thin, short, small, beautiful and low power consumption due to their high energy consumption and large radiation generation characteristics, as well as the limited flattening space of their products. Therefore, light and thin flat-panel displays have gradually replaced traditional heavy cathode ray tube displays. Common flat-panel displays include liquid crystal displays (LCD) and thin film transistor liquid crystal displays (TFT-LCD). Liquid crystal display modules have been widely used in car systems to meet the strong demand for full-screen displays in the automotive market. However, the liquid crystal display modules in the prior art have the following hidden dangers when used in car systems: when a vehicle rear-ends another vehicle, the liquid crystal display module may be hit by the front structure of the vehicle, such as the dashboard or windshield, as well as the vehicle in front, causing the liquid crystal display module to shatter and splash, thereby posing a serious threat to user safety. Summary of the invention

[0049] Embodiment 2

[0050] See also Figure 1-13 The present invention provides another technical solution of a TFT-LCD display module: the module housing 200 includes a support body 300, and a TFT-LCD display screen 100 is mounted in a mounting groove at the front of the support body 300; the support body 300 is slidably arranged in a receiving cavity opened at the top of a storage body 400, a slider fixed to the rear side of the support body 300 is slidably arranged in a vertical groove on the rear side of the storage body 400, and a force transmission seat 500 fixed to the rear side of the slider is slidably matched on the rear side of the storage body 400; the force transmission seat 500 is fixed to the rear side of the slider. A first permanent magnet 510 is provided on the surface, and the first permanent magnet 510 is arranged opposite to the first magnetic pole surface of the driving electromagnet 600 arranged at the lower rear side of the storage body 400; when the driving electromagnet 600 is energized, the driving electromagnet 600 drives the first permanent magnet 510 to move in the direction away from the first magnetic pole surface; when the driving electromagnet 600 is de-energized, the first permanent magnet 510 moves in the direction of the first magnetic pole surface under the action of the magnetic attraction force of the driving electromagnet 600, and adheres to the driving electromagnet 600.

[0051] The working principle and technical effects of the above technical solution are as follows:

[0052] The above-mentioned embodiment 2 provides another technical solution of the present invention. In the TFT-LCD display module, the structure of the TFT-LCD display screen 100 is the same as that of the embodiment 1. The module housing 200 adopts another structure. The module housing 200 includes a support body 300. The TFT-LCD display screen 100 is mounted in the mounting groove at the front of the support body 300, so as to facilitate the stable connection of the TFT-LCD display screen 100. The TFT-LCD display screen 100 can be completely stored in the mounting groove. The storage body 400 is used to be connected in the center console to achieve the fixed installation of the present invention. The support body 300 is slidably arranged in the accommodating cavity opened at the top of the storage body 400, and can slide out upward or slide in downward in the accommodating cavity of the storage body 400. A first permanent magnet 510 is arranged on the lower surface of the force transmission seat 500. The first permanent magnet 510 is arranged opposite to the first magnetic pole surface of the driving electromagnet 600 arranged below the rear side of the storage body 400. Under normal conditions, the first permanent magnet 510 fits under the magnetic attraction of the driving electromagnet 600. On the driving electromagnet 600, the support body 300 is stored in the accommodating cavity of the storage body 400. When the vehicle is started, the power is turned on, and the driving electromagnet 600 is automatically energized. When the driving electromagnet 600 is energized, the magnetic force direction of the driving electromagnet 600 is changed, so that the first magnetic pole surface of the driving electromagnet 600 and the first permanent magnet 510 repel each other, so that the driving electromagnet 600 drives the first permanent magnet 510 to move in a direction away from the first magnetic pole surface, and the first permanent magnet 510 drives the force transmission seat 50 0 rises, the force transmission seat 500 drives the support body 300 and the TFT-LCD display screen 100 on the support body 300 to slide upward to the top of the accommodating cavity of the storage body 400 through the slider, so as to be convenient for use; when the vehicle is powered off, the driving electromagnet 600 is automatically powered off, at this time, the first permanent magnet 510 moves toward the direction of the first magnetic pole surface under the magnetic attraction of the driving electromagnet 600, and the first permanent magnet 510 and the first magnetic pole surface of the driving electromagnet 600 are attracted to each other, so as to be attached to the driving electromagnet 600;The above structure is adopted to realize that the TFT-LCD display screen 100 on the support body 300 is automatically retracted into the accommodating cavity of the storage body 400 after power failure, so as to effectively protect the TFT-LCD display screen 100 and prevent the TFT-LCD display screen 100 from being broken due to accidental collision. Since some modern vehicles are equipped with a collision sensing system, the power supply can be automatically cut off when the vehicle suffers a major collision to protect the safety of the vehicle and passengers. Other structures that require power control to retract cannot control the TFT-LCD display screen 100 to retract when power is off. At this time, the TFT-LCD display screen 100 is easily broken by impact, and the probability of fragments flying may occur, posing a threat to the safety of users, especially now that the screen of the car machine is getting bigger and bigger, and the corresponding risk is getting higher and higher. The driving control of the driving electromagnet 600 inside the present invention effectively solves the problem that the TFT-LCD display screen 100 cannot be retracted when the power is off. The present invention automatically retracts the TFT-LCD display screen 100 into the accommodating cavity of the storage body 400 after the vehicle is powered off or hit, preventing the fragments generated by the TFT-LCD display screen 100 from flying, and has high safety, and is particularly suitable for use in new energy electric vehicles in the prior art. ;

[0053] The force transmission seat 500 is connected to the force transmission bracket 700, and the force transmission bracket 700 is connected to the rear side of the storage body 400. A plurality of transverse shafts 410 are fixedly connected to the rear side of the storage body 400. The plurality of transverse shafts 410 are slidably matched with the force frame 420. The force frame 420 is cooperatively arranged on the rear side of the force transmission bracket 700. When the force frame 420 is subjected to pressure, the force frame 420 slides on the plurality of transverse shafts 410 toward the direction of the force transmission bracket 700, so that the force transmission bracket 700 drives the support body 300 and the TFT-LCD display screen 100 to be stored in the accommodating cavity.

[0054] The working principle and technical effects of the above technical solution are as follows:

[0055] In order to further improve the stability of the TFT-LCD display screen 100 when it is stored in the storage cavity of the storage body 400, and reduce the probability that the LCD display module may be hit by the front structure of the vehicle when the vehicle rear-ends others, resulting in the probability of the LCD display module being broken and spattered, the above structure is specially designed, wherein the force frame 420 is connected to the inside of the front structure of the vehicle, such as connected to the center console. When the vehicle rear-ends, the front structure of the vehicle is hit, which will generate a backward thrust on the force frame 420. At this time, the force frame 420 slides on the multiple horizontal shafts 410 toward the direction of the force transmission bracket 700, so that the force transmission bracket 700 drives the support body 300 and the TFT-LCD display screen 100 to be stored in the storage cavity, and cooperates with the driving electromagnet 600 to realize the rapid retraction of the TFT-LCD display screen 100.

[0056] The force transmission bracket 700 includes two vertical support rods 710 relatively rotated at the left and right ends of the force transmission seat 500, the two vertical support rods 710 are rotatably connected to the upper ends of the two L-shaped slides 720, and the two L-shaped slides 720 slide relatively in the two L-shaped slide grooves on the left and right sides of the horizontal slide groove frame 730, and the horizontal slide groove frame 730 is fixed on the rear side surface of the storage body 400; the rear ends of the two L-shaped slides 720 are rotatably connected to the two horizontal support rods 740 one by one, and the two horizontal support rods 740 are relatively rotated on the left and right sides of the force transmission frame body 750, and the force transmission frame body 750 is slidably arranged on the guide rod 760, and the guide rod 760 is fixedly connected to the rear side surface of the storage body 400, and the axis of the guide rod 760 is parallel to the axis of the horizontal axis rod 410; the force frame 420 is slidably arranged on the guide rod 760 and is located on the rear side of the force transmission frame body 750.

[0057] When the support body 300 slides out upward to the top of the storage body 400, the force transmission seat 500 can drive one end of the two vertical support rods 710 to move upward, and the other end of the two vertical support rods 710 can drive the two L-shaped slide seats 720 to move toward each other in the two L-shaped slide grooves on the left and right sides of the horizontal slide groove frame 730 to achieve mutual approach. When the two L-shaped slide seats 720 approach each other, they can drive one end of the two horizontal support rods 740 to approach each other, and the other end of the two horizontal support rods 740 drives the force transmission frame body 750 to move on the guide rod 760 away from the storage body 400, that is, to move toward the front of the vehicle and fit with the rear side of the force frame 420; when the front structure of the vehicle is hit and the force frame 420 is pushed backward, the force frame 420 slides on the multiple horizontal axis rods 410 toward the storage body 400, thereby The frame 750 generates a backward thrust, causing the force transmission frame 750 to move on the guide rod 760 toward the storage body 400. At this time, the force transmission frame 750 drives one end of the two horizontal support rods 740 to move in the direction of the storage body 400, and the angle between the two horizontal support rods 740 becomes larger. The other ends of the two horizontal support rods 740 drive the two L-shaped slides 720 to move away from each other in the two L-shaped slide grooves on the left and right sides of the horizontal slide groove frame 730. When the two L-shaped slides 720 move away from each other, the angle between the two vertical support rods 710 becomes larger, and the upper ends of the two vertical support rods 710 drive the force transmission seat 500 to move downward, thereby controlling the support body 300 to slide downward into the storage body 400, and when the vehicle suffers a major collision and automatically cuts off the power supply, the magnetic attraction effect of the driving electromagnet 600 is cooperated to further increase the retraction speed.

[0058] The connection between the force transmission frame 750 and the guide rod 760 is a rectangular connecting block 770, which is made of elastic rubber, so that when the guide rod 760 is slightly deformed, it will not affect the relative sliding of the guide rod 760 and the rectangular connecting block 770. At this time, the rectangular connecting block 770 can be separated from the guide rod 760 to prevent the force transmission frame 750 from being unable to move in the direction of the storage body 400 and causing jamming.

[0059] A reset spring 780 is fixedly connected between the inner side surfaces of the L-shaped slides 720 and the two horizontal slide frames 730. When the support body 300 is retracted into the storage body 400, the two reset springs 780 drive the two L-shaped slides 720 away from each other, thereby improving the collection efficiency. Multiple reset forces are controlled synchronously, and the effect is better.

[0060] The rear side surface of the driving electromagnet 600 is a second magnetic pole surface, and the second magnetic pole surface is arranged in correspondence with the second permanent magnet 790 arranged on the front side surface of the force frame 420; when the driving electromagnet 600 is energized, the driving electromagnet 600 drives the second permanent magnet 790 to move in a direction away from the second magnetic pole surface, at this time, the support body 300 extends upward to the outside of the storage body 400 faster and more stably; when the driving electromagnet 600 is powered off, the second permanent magnet 790 moves in the direction of the second magnetic pole surface under the action of the magnetic attraction of the driving electromagnet 600, and adheres to the driving electromagnet 600. At this time, the effect of the support body 300 driving the TFT-LCD display screen 100 to be stored in the storage body 400 is effectively improved.

[0061] The vertical support rod 710 includes an upper rod body hinged to the force transmission seat 500 and a lower rod body hinged to the L-shaped slide seat 720. The upper end of the lower rod body is slidably arranged in the telescopic slideway of the upper rod body, and the limit column on the lower rod body slides in the side sliding hole of the upper rod body. An elastic buffer body is fixedly connected between the lower rod body and the inner side of the telescopic slideway. The structural setting of the vertical support rod 710 enables it to have a certain elastic buffer effect on the support of the force transmission seat 500, the support body 300 and the TFT-LCD display screen 100.

[0062] An upper limit stopper 430 is fixedly connected to the rear side surface of the storage body 400, and an upper elastic buffer block is provided on the lower surface of the upper limit stopper 430. The upper elastic buffer block is arranged directly above the force transmission seat 500 to facilitate buffering when the support body 300 and the TFT-LCD display screen 100 move upward to the position, play a role of limiting, and reduce the damage caused by impact to the TFT-LCD display screen 100.

[0063] A lower elastic buffer block is provided on the bottom surface of the storage cavity of the storage body 400, and the lower elastic buffer block is located directly below the support body 300, so as to provide buffering when the support body 300 and the TFT-LCD display screen 100 move downward to the right position, play a role of limiting, and reduce the damage caused by impact to the TFT-LCD display screen 100.

[0064] The module shell 200 also includes an airbag mechanism 800; the airbag mechanism 800 includes an expansion protection airbag 810 adhered to the circular groove on the front side of the storage body 400, and the expansion protection airbag 810 is connected to a plurality of buffer air supply airbags 830 sleeved on a plurality of transverse shafts 410 through a plurality of one-way air inlet pipes 820, and the plurality of one-way air inlet pipes 820 are all penetrated in the through-tube holes of the storage body 400; the plurality of buffer air supply airbags 830 are all located between the force-bearing frame 420 and the rear side of the storage body 400, and when the force-bearing frame 420 is pressed and approaches the rear side of the storage body 400, the plurality of buffer air supply airbags 830 are compressed, so that the gas in the plurality of buffer air supply airbags 830 enters the expansion protection airbag 810 through the plurality of one-way air inlet pipes 820, so that the expansion protection airbag 810 is expanded, and thus the expansion protection airbag 810 is shielded on the front side of the storage body 400.

[0065] When the front structure of the vehicle is hit and a backward thrust is generated on the force-bearing frame 420, the force-bearing frame 420 slides on the multiple transverse shafts 410 toward the storage body 400, thereby squeezing the multiple gas-filled buffer air supply airbags 830. At this time, the multiple buffer air supply airbags 830 can play a role in buffering and energy absorption, and the gas in the multiple buffer air supply airbags 830 can also enter the inflatable protective airbag 810 through multiple one-way air inlet pipes 820 to expand the inflatable protective airbag 810, so that the inflatable protective airbag 810 is shielded on the front side of the storage body 400, thereby effectively shielding the front side of the storage body 400, preventing the storage body 400 from being hit and falling when installed on the outside of the center console to cause damage to the user. This is equivalent to a new airbag protection structure in addition to the vehicle airbag, which further protects the safety of the user.

[0066] The top pressure plate 440 is slidably connected in the horizontal sliding opening at the top of the storage body 400, and the front side of the top pressure plate 440 is connected to the inner side of the horizontal sliding opening through multiple tension springs, and the cleaning cotton strip on the rear side of the top pressure plate 440 contacts the TFT-LCD display screen 100 at the front of the support body 300. The setting of this structure can not only clean the surface of the TFT-LCD display screen 100 when the TFT-LCD display screen 100 is raised or lowered, but also generate backward pressure on the cleaning cotton strip and the top pressure plate 440 as the TFT-LCD display screen 100 is reset when the vehicle is hit, so that the top pressure plate 440 can compress the multiple tension springs backward and store them in the horizontal sliding opening, thereby expanding the size of the top opening of the storage body 400 to prevent the TFT-LCD display screen 100 from being unable to be stored in the storage body 400 when it is slightly bent.
