[0024] As Figures 1 to 3 shown, in this embodiment, a waterproof, shockproof and wear-resistant LED display panel for displaying images includes: A box body 1; A display component 2, provided on the box body 1 and used for displaying the image to be displayed; A waterproof component 3, provided on the box body 1 and used for preventing rain or snow from eroding the display component 2; A shockproof component 4; provided below the box body 1 and used for reducing the vibration received by the box body 1; Among them, the waterproof component 3 includes a waterproof mechanism and a driving mechanism. The waterproof mechanism includes a rainproof cloth, which is laid around the box body 1 to prevent rain or snow from eroding the display component 2. The driving mechanism is used to drive the waterproof mechanism to spread the rainproof cloth and drive the waterproof mechanism to fold it inside the box body 1.

[0025] Specifically, in this embodiment, the display panel consists of a box body 1, a display component 2, a waterproof component 3 and a shockproof component 4. The box body 1 is arranged above the shockproof component 4. The shockproof component 4 can play a shock-absorbing role and reduce the vibration intensity of the box body 1. The display component 2 is arranged on one side of the box body 1 and can display the image to be displayed. The waterproof component 3 is arranged above the box body 1 and can effectively prevent rain and snow from eroding the display component 2.

[0026] In addition, in this embodiment, the waterproof component 3 is composed of a waterproof mechanism and a driving mechanism. The waterproof mechanism includes a rain cover arranged above and around the box body 1, which can effectively prevent rain and snow from falling on the box body 1 or the display component 2. The driving mechanism can drive the waterproof mechanism to operate to open the rain cover, and at the same time can drive the waterproof component 3 to fold and drive the waterproof component 3 into the box body 1.

[0027] That is to say, the shockproof component 4 is arranged below the box body 1, which can reduce the vibration intensity of the box body 1; the display component 2 is arranged on one side of the box body 1, which can display the image to be displayed on the display panel; the waterproof component 3 is arranged above the box body 1; the waterproof mechanism in the waterproof component 3 can prevent rain or snow from eroding the display component 2; the driving mechanism can drive the waterproof component 3 to fold and drive the waterproof component 3 into the box body 1.

[0028] It should be noted that the specific structure of the display component 2 is not limited in this application and can be reasonably selected according to actual conditions. Specifically, in this embodiment, the display component 2 can be a CRT display, an LCD display or an LED display, as long as it can display images.

[0029] Specifically, such as Figures 1 to 3 As shown, in this embodiment, the display component 2 includes a display surface 21 arranged on the side outside the box body 1, which is used to display the image to be displayed. A plurality of display units 22 are provided on the display surface 21, which are used to emit light of different colors according to the image. A display film is provided on the surface of the display unit 22, which is used to protect the display unit 22; the display component 2 includes a display cabinet 23 arranged in the box body 1, and the display cabinet 23 is sealed with the box body 1. A control system is provided in the display cabinet 23, which is used to control the display unit 22 to emit light to form the image.

[0030] That is to say, the display component 2 consists of a display unit 22 and a control system. The display unit 22 is arranged on one side of the box body 1 to form a display screen. A display film is provided on the outside of the display screen. The display film is a transparent structure and is connected to the box body 1 around the display screen. A display cabinet 23 is provided inside the box body 1. The display cabinet 23 is sealed and connected to the box body 1 to play a waterproof role. The control system is arranged in the display cabinet 23 to effectively prevent rainwater from eroding the control system.

[0031] Furthermore, in this embodiment, the display film is a diamond-like carbon (DLC) film layer or a carbon nitride (CNT) film layer. Both DLC and CNT have hardness comparable to diamond. Due to their relatively high hardness, they protect the display unit. Furthermore, as a new type of hard film material, DLC combines the excellent properties of both diamond and graphite, such as high hardness, high wear resistance, high thermal conductivity, high resistivity, good optical transparency, and chemical inertness. It exhibits excellent optical properties, ensuring the display effect of display unit 22 while also providing a waterproofing effect.

[0032] It should be noted that the specific structure of the driving mechanism is not limited in this application and can be reasonably selected according to actual conditions, as long as it can drive the waterproof component 3 to fold and drive the waterproof component 3 into the box body 1.

[0033] Specifically, such as Figures 1 to 6 As shown, in this embodiment, the driving mechanism includes a folding motor 31 and a folding shaft 33 disposed within the housing 1. The folding motor 31 is used to drive the folding shaft 33 to rotate. The folding shaft 33 is provided with a support rod 32. One end of the support rod 32 extends from the top of the housing 1. The upper end of the support rod 32 can freely rotate within the upper portion of the housing 1 and within the housing 1. The top end of the support rod 32 is connected to a driving motor 5. The driving motor 5 has two output ends disposed opposite each other. The driving motor 5 is used to drive the waterproof mechanism to extend the tarpaulin. Both output ends of the driving motor 5 are sheathed with a folding beam 51. Both output ends of the driving motor 5 are connected to a transmission gear set 6.

[0034] Furthermore, in this embodiment, the driving mechanism is driven by a folding motor 31 and a driving motor 5. The folding motor 31 can drive the rotating shaft to rotate, and the two are transmitted through gears, so that the support rod 32 rotates 180°, so that the driving motor 5 on the support rod 32 moves in the box body 1 and above the box body 1. The driving motor 5 is a bidirectional motor, which can simultaneously operate the transmission gear sets 6 at both ends of the driving motor 5. A water collecting tank is provided in the box body 1 to collect rainwater or snow attached to the waterproof mechanism.

[0035] That is to say, this motor drives the folding rotating shaft 33 to rotate through gear transmission, so that the support rod 32 swings 180°, enabling the driving motor 5 to move within the box body 1 and above the box body 1. The driving motor 5 can simultaneously drive the transmission gear sets 6 at both output ends to operate synchronously.

[0036] It should be noted that in this application, the specific structure of the transmission gear set 6 is not limited and can be reasonably selected according to the actual situation, as long as the bidirectional transmission of the rotational force can be achieved.

[0037] Specifically, as Figure 6 shown, in this embodiment, the transmission gear set 6 includes a first helical gear 61 provided at the output end of the driving motor 5. Two first gears 63 are provided on the inner upper part of the folding cross beam 51 and are arranged opposite to each other. A second helical gear 62 is provided on one side of each of the two first gears 63. The second helical gear 62 is in transmission with the first helical gear 61. Second gears 64 are provided in the folding cross beam 51 and are in transmission with the two first gears 63 respectively. A driving wheel 7 is provided on one side of the second gear 64, and a driving rope is provided on the driving wheel 7.

[0038] That is to say, the driving motor 5 drives the first helical gear 61 to rotate, causing it to drive the two second helical gears 62. Since the second helical gear 62 is coaxially connected to the first gear 63, the first gear 63 rotates synchronously with the second helical gear 62. The meshing transmission of the first gear 63 causes the second gear 64 to rotate, thereby causing the two driving wheels 7 to rotate. The rotation of the driving wheels 7 enables the driving rope to wind around or disengage from the driving wheels 7.

[0039] It should be noted that in this application, the specific structure of the waterproof mechanism is not limited and can be reasonably selected according to the actual situation, as long as it can prevent rain or snow from eroding the display component 2.

[0040] Specifically, as Figures 4 to 5 shown, in this embodiment, auxiliary beams 52 are provided on both sides of the folding cross beam 51. Telescopic sleeves 53 are provided at one end of each of the two folding cross beams 51. The telescopic sleeves 53 are sleeved on one end of the folding cross beam 51 and the auxiliary beam 52 and are slidably connected to the folding cross beam 51 and the auxiliary beam 52. A return spring 57 is provided inside the telescopic sleeve 53. The return spring 57 connects the outer wall of one end of the folding cross beam 51 and the inner wall of the telescopic sleeve 53. Telescopic rods 54 are connected to both sides of the telescopic sleeve 53. The telescopic rods 54 are of a hollow structure, and one end is communicated with the telescopic sleeve 53 and the other end is communicated with a sliding sleeve 56. The sliding sleeve 56 is provided at both ends of a rain cloth box 55 located on both sides of the folding cross beam 51 and is slidably connected to the rain cloth box 55.

[0041] Furthermore, auxiliary beams 52 are provided on both sides of the telescopic sleeve 53. Raincloth boxes 55 are provided on the outer sides of the two auxiliary beams 52. Sliding sleeves 56 are provided at both ends of the raincloth boxes 55. The telescopic sleeve 53 is sleeved on one end of the folding cross beam 51 and the auxiliary beam 52. The telescopic rod 54 connects the telescopic sleeve 53 and the sliding sleeve 56. A return spring 57 is arranged in the telescopic sleeve 53, enabling the telescopic sleeve 53 and the sliding sleeve 56 to extend outwards to the maximum extent. The telescopic rod 54 can be contracted by an external force, reducing the distance between the raincloth box 55 and the auxiliary beam 52.

[0042] That is to say, the telescopic sleeve 53 and the sliding sleeve 56 can slide synchronously through the connection of the telescopic rod 54, thereby reducing the length of the waterproof mechanism and making the length of the waterproof mechanism less than the length of the box body 1. The telescopic sleeve 53 and the sliding sleeve 56 can be reset through the return spring 57. The telescopic rod 54 can be pushed to contract by an external force, thereby reducing the width of the waterproof mechanism and making the width of the waterproof mechanism less than the width of the box body 1, facilitating the folding of the waterproof mechanism into the box body 1.

[0043] Specifically, as Figures 4 to 8 shown, in this embodiment, guide wheels 71 are provided at positions corresponding to the two drive wheels 7 in the telescopic sleeve 53 for guiding the drive rope into the telescopic rod 54. A first transmission wheel 72 is provided in the telescopic rod 54 corresponding to the auxiliary beam 52. The first transmission wheel 72 is connected to a first transmission shaft 73 through a damping member 721. The damping member 721 is used to provide the damping force for the connection between the first transmission wheel 72 and the first transmission shaft 73. The first transmission shaft 73 is located in the auxiliary beam 52. A ceiling raincloth is provided on the first transmission shaft 73. The ceiling raincloth extends from one side of the auxiliary beam 52 and is connected to the raincloth box 55 and the sliding sleeve 56.

[0044] That is to say, guide wheels 71 are provided in the telescopic sleeve 53. The guide wheels 71 can guide the drive rope into the telescopic rod 54. First transmission wheels 72 are provided at both ends of the auxiliary beam 52. The drive rope winds around the first transmission wheels 72. When the drive rope moves, it can drive the first transmission wheels 72 to rotate. The first transmission wheels 72 and the first transmission shaft 73 are connected through the damping member 721. The damping member 721 can provide the damping force for the transmission between the two. The ceiling raincloth is wound on the first transmission shaft 73. Without external intervention, the drive rope drives the first transmission wheels 72 to rotate. Through the damping force provided by the damping member 721, the first transmission shaft 73 can be driven to rotate, enabling the ceiling raincloth to be wound on the first transmission shaft 73. One end of the ceiling raincloth is connected to the raincloth box 55. The damping force cannot drive the first transmission shaft 73 to rotate to move the raincloth box 55. At this time, the drive rope drives the first transmission wheels 72 to rotate but cannot drive the first transmission shaft 73 to rotate.

[0045] It should be noted that the specific structure of the damping member 721 in this application is not limited and can be reasonably selected according to the actual situation. Specifically, in this application, the damping member 721 can be a damper, a damping sheet, or a rubber ring, as long as it can provide the damping force for the transmission between the first transmission wheel 72 and the first transmission shaft 73.

[0046] Specifically, as Figures 4 to 10 shown, in this embodiment, a second transmission shaft 75 is provided in the rain cloth box 55. A side rain cloth is provided on the second transmission shaft 75. A counterweight is connected to the end of the side rain cloth. Both ends of the second transmission shaft 75 are connected with second transmission wheels 74. The driving rope is wound around the first transmission wheel 72 and then connected to the second transmission wheel 74. The middle parts of the first transmission shaft 73 and the second transmission shaft 75 are made of flexible materials.

[0047] That is to say, an opening is provided below the rain cloth box 55 for laying out the rain cloth. A second transmission shaft 75 is provided in the rain cloth box 55. Second transmission wheels 74 are provided at both ends of the rain cloth box 55 in the sliding sleeve 56 and are connected to the second transmission shaft 75. A driving rope is wound around the second transmission wheel 74. The driving rope can drive the second transmission wheel 74 to rotate, so that the second transmission shaft 75 rotates, and the side rain cloth is wound on the second transmission shaft 75. By driving the driving wheel 7 through the driving motor 5, the driving rope on the driving wheel 7 is separated from the driving wheel 7. By the gravitational pull of the counterweight on the side rain cloth, the second transmission shaft 75 rotates, and the side rain cloth is laid out on the side of the box body 1.

[0048] In addition, by driving the driving motor 5 to wind the driving rope around the driving wheel 7, the driving rope drives the second transmission wheel 74 to rotate, and the second transmission shaft 75 winds up the side rain cloth until the side rain cloth is completely wound on the second transmission shaft 75. The pulling force of the driving rope pulls the rain cloth box 55 through the second driving wheel 7, causing the telescopic rod 54 to contract. After the telescopic rod 54 is completely contracted, the pulling force of the driving rope moves the telescopic sleeve 53 inward through the transmission wheel until the contraction of the telescopic sleeve 53 is completed. The middle parts of the first transmission shaft 73 and the second transmission shaft 75 are both made of flexible materials. During the contraction process of the telescopic sleeve 53, the middle parts of the first transmission shaft 73 and the second transmission shaft 75 bend downward, reducing the lengths of the first transmission shaft 73 and the second transmission shaft 75. At the same time, a similar spring structure can also be used, as long as it can achieve bending and length reduction in the unloaded tensile state at both ends.

[0049] It should be noted that the specific structure of the shockproof component 4 in this application is not limited and can be reasonably selected according to the actual situation, as long as it can reduce the vibration received by the box body 1.

[0050] Specifically, as Figures 1 to 3As shown, in this embodiment, the shockproof assembly 4 includes a bottom plate 41 and shockproof columns 42. The shockproof columns connect the bottom plate 41 to the bottom of the box body 1. A shockproof sleeve 43 is sleeved on the shockproof columns 42, and a shockproof spring is arranged inside the shockproof sleeve 43 to reduce the vibration received by the box body 1.

[0051] That is to say, the shockproof assembly is composed of a bottom plate 41 and shockproof columns 42. The shockproof columns 42 connect the bottom plate 41 and the box body 1. The bottom plate 41 is a grid-like structure. A shockproof sleeve 43 is provided at the top of the shockproof columns 42, and a shockproof spring is arranged inside the shockproof sleeve 43 for connection. The shockproof spring can reduce the influence of ground vibration on the box body 1.

[0052] Generally speaking, this application provides an LED display panel with waterproof, shockproof and anti-wear functions. When it rains or snows outdoors, the folding motor 31 drives the folding rotating shaft 33 to rotate, so that the waterproof mechanism on the support rod 32 rotates above the box body 1. The driving motor 5 is used to drive the driving wheel 7 to rotate, so that the driving rope on the driving wheel 7 leaves the driving wheel 7. The reset spring 57 first resets the telescopic sleeve 53 and the sliding sleeve 56. The telescopic rod 54 extends due to the gravity of the rain cloth box 55, so that the ceiling rain cloth is spread on the top of the box body 1. The gravity of the counterweight pulls the side rain cloth, so that the second transmission shaft 75 rotates, and the driving rope is wound around the second transmission wheel 74 to spread the side rain cloth on the side of the box body 1; when it stops raining or snowing outdoors, the driving motor 5 is used to wind the driving rope around the driving wheel 7, and the driving rope makes the second transmission wheel 74 rotate, so that the second transmission shaft 75 rolls up the side rain cloth until the side rain cloth is completely rolled on the second transmission shaft 75. The pulling force of the driving rope pulls the rain cloth box 55 through the second driving wheel 7, so that the telescopic rod 54 contracts. The driving rope drives the first transmission wheel 72 to rotate, and the damping force provided by the damper 721 can drive the first transmission shaft 73 to rotate, so that the ceiling rain cloth can be rolled on the first transmission shaft 73. When the telescopic rod 54 is completely retracted, the pulling force of the driving rope makes the telescopic sleeve 53 move inward through the transmission wheel until the telescopic sleeve 53 is completely retracted. At the same time, the middle parts of the first transmission shaft 73 and the second transmission shaft 75 are bent, and the folding motor 31 drives the folding rotating shaft 33 to rotate, so that the waterproof mechanism on the support rod 32 rotates into the box body 1.

[0053] In summary, the above embodiments provided by the present invention only exemplarily illustrate the principles and effects of the present invention, rather than limiting the present invention.
