Description

Technical Field

[0001] This invention relates to the field of display module technology, specifically to a display module with surface dustproof function. Background Technology

[0002] With the continuous progress of society and the rapid development of technology, electronic products are becoming increasingly popular. Among these products, there are usually LCD modules. Simply put, an LCD module is a screen plus a backlight assembly. The display component of an LCD TV is the LCD module, which is equivalent to the picture tube in a CRT. Therefore, the LCD module is extremely important to the electronic product itself.

[0003] Existing LCD modules do not have dustproof features. If dust accumulates on the surface of the LCD module for a long time, it can easily damage the LCD module and reduce its lifespan. Furthermore, because the LCD module is fixed inside the TV protective casing, it is inconvenient for staff to clean it. Summary of the Invention

[0004] The purpose of this invention is to provide a display module with surface dustproof function to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a display module with surface dustproof function, comprising a protective shell, a display module fixed to the inner wall of the protective shell, heat dissipation holes provided on the side wall of the protective shell, a dustproof mesh fixed to the inner wall of the heat dissipation holes, a motor fixed to the top of the protective shell, a rotating rod fixed to the output end of the motor, and fan blades fixed to the outer wall of the rotating rod. Starting the motor causes the rotating rod to drive the fan blades to rotate, thereby dissipating heat from the inside of the protective shell and improving the heat dissipation effect. A cleaning mechanism is provided on the outer wall of the rotating rod, and a control mechanism is provided inside the protective shell. The cleaning mechanism includes:

[0006] A reciprocating lead screw, the two ends of which are rotatably mounted on the inner wall of the protective shell, and the rotating rod is connected to the reciprocating lead screw via a transmission belt;

[0007] A threaded sleeve, which is threadedly connected to the outer wall of a reciprocating lead screw;

[0008] The cleaning brush is fixed to the side wall of the threaded sleeve. When the rotating rod rotates, the transmission belt drives the reciprocating screw to rotate, which in turn allows the threaded sleeve to move on the reciprocating screw. This allows the cleaning brush to move in contact with the dustproof mesh, thereby cleaning the mesh openings and preventing them from becoming clogged and affecting heat dissipation inside the protective shell.

[0009] Preferably, a guide rod is fixed to the inner wall of the protective shell. The guide rod passes through the threaded sleeve and is slidably connected to the threaded sleeve at the point of penetration. By setting the guide rod, the threaded sleeve can be guided.

[0010] Preferably, the control mechanism includes a sleeve fixed to the inner wall of the protective shell, a sleeve rod slidably mounted on the inner wall of the sleeve, a connecting spring fixed to the top of the sleeve rod, and the top of the connecting spring fixed to the inner wall of the sleeve. By setting the connecting spring, the sleeve rod can be reset.

[0011] Preferably, a support plate is fixed to the inner wall of the protective shell, a rotating sleeve is rotatably installed on the top of the support plate, an arc-shaped groove is provided on the rotating sleeve, a sliding rod is fixed to the outer wall of the sleeve rod, the sliding rod passes through the arc-shaped groove, and the sliding rod fits against the passage of the arc-shaped groove.

[0012] Preferably, a rotating shaft is fixed to the bottom of the rotating sleeve, a take-up wheel is fixed to the bottom of the rotating shaft, a pull rope is fixed to the outer wall of the take-up wheel, a connecting seat is fixed to the end of the pull rope away from the take-up wheel, and a cleaning cloth is fixed to the back of the connecting seat. When the motor is started, the rotating rod can be rotated. Through the cooperation of the transmission belt, reciprocating screw, threaded sleeve, transmission plate, L-shaped connecting rod, sleeve rod, slide rod, arc-shaped slide groove, rotating sleeve, rotating shaft, take-up wheel, pull rope, connecting seat and cleaning cloth, the cleaning cloth can be moved to conform to the surface of the display module, thereby achieving the effect of cleaning the surface of the display module.

[0013] Preferably, a transmission spring is fixed to the side wall of the connecting seat, and the side of the transmission spring away from the connecting seat is fixed to the inner wall of the protective shell. An L-shaped connecting rod is fixed to the outer wall of the sleeve rod, and a transmission plate is fixed to the end of the L-shaped connecting rod away from the sleeve rod. The transmission plate is slidably installed on the inner wall of the protective shell. When the threaded sleeve moves to a position where it does not compress the transmission plate, the connecting spring is in a compressed state, which allows the sleeve rod to move downward, driving the slide rod to move downward in the arc-shaped slide groove. Through the cooperation of the rotating sleeve, rotating shaft, transmission spring, winding wheel and connecting seat, the cleaning cloth can be restored to its original position, thus enabling the next cleaning.

[0014] Preferably, a fixing rod passes through the connecting seat, the fixing rod is slidably connected to the through portion of the connecting seat, and the fixing rod is fixed to the inner wall of the protective shell.

[0015] Preferably, the cleaning cloth is provided in two sets, and the two sets of cleaning cloth are arranged in a mirror image of the protective shell.

[0016] Preferably, the bottom of the protective shell is provided with a dust discharge groove, a sealing plate is slidably installed on the bottom of the protective shell, and a handle is fixed to the bottom of the sealing plate.

[0017] Preferably, the transmission plate is provided in two sets, and the two sets of transmission plates are arranged in a mirror image with respect to the protective shell.

[0018] Compared with the prior art, the present invention provides a display module with surface dustproof function, which has the following beneficial effects:

[0019] 1. This display module with surface dustproof function can rotate the rotating rod when the motor is started. Through the cooperation of the transmission belt, reciprocating screw, threaded sleeve, transmission plate, L-shaped connecting rod, sleeve rod, slide rod, arc-shaped slide groove, rotating sleeve, rotating shaft, winding wheel, pull rope, connecting seat and cleaning cloth, the cleaning cloth can be moved to adhere to the surface of the display module, thereby achieving the effect of cleaning the surface of the display module.

[0020] 2. When the rotating rod rotates, the transmission belt drives the reciprocating screw to rotate, which in turn allows the threaded sleeve to move on the reciprocating screw. This allows the cleaning brush to move along the dustproof mesh, thus cleaning the mesh openings and preventing them from becoming clogged and affecting heat dissipation inside the protective shell.

[0021] 3. This display module with surface dustproof function allows the sleeve to move downwards when the threaded sleeve moves to a position that does not press against the transmission plate. Because the connecting spring is in a compressed state, the sleeve rod can move downwards, causing the slide rod to move downwards in the arc-shaped slide groove. Through the cooperation of the rotating sleeve, rotating shaft, transmission spring, winding wheel and connecting seat, the cleaning cloth can be restored to its original position, thus enabling the next cleaning.

[0022] 4. This display module with surface dustproof function can start by starting the motor, which can drive the fan blades to rotate, thereby dissipating heat from the inside of the protective shell and making the heat dissipation effect inside the protective shell better.

[0031] like Figure 1-7 As shown, the present invention provides a technical solution: a display module with surface dustproof function, including a protective shell 1, a display module 2 set fixed on the inner wall of the protective shell 1, heat dissipation holes 3 opened on the side wall of the protective shell 1, two sets of heat dissipation holes 3 are provided, and the two sets of heat dissipation holes 3 are symmetrically arranged with the center line in the vertical direction of the protective shell 1 as the axis of symmetry. The heat dissipation holes 3 can achieve the effect of heat dissipation inside the protective shell 1. A dustproof mesh 4 is fixed on the inner wall of the heat dissipation holes 3. By setting the dustproof mesh 4, the dustproof mesh 4 can achieve the effect of dustproofing and preventing dust from entering the protective shell 1. A motor 5 is fixed on the top of the protective shell 1, a rotating rod 6 is fixed on the output end of the motor 5, and a fan blade 7 is fixed on the outer wall of the rotating rod 6. By starting the motor 5, the rotating rod 6 can be rotated, thereby driving the fan blade 7 to rotate, which can achieve the effect of heat dissipation inside the protective shell 1. A cleaning mechanism 8 is provided on the outer wall of the rotating rod 6, and a control mechanism 9 is provided inside the protective shell 1.

[0032] The aforementioned cleaning mechanism 8 includes a transmission belt 801, a reciprocating screw 802, a threaded sleeve 803, a guide rod 805, and cleaning brushes 804. The upper and lower ends of the reciprocating screw 802 are rotatably mounted on the inner wall of the protective shell 1. The reciprocating screw 802 is connected to the rotating rod 6 via the transmission belt 801. Thus, when the rotating rod 6 rotates, the transmission belt 801 can rotate the reciprocating screw 802. A threaded sleeve 803 is threadedly connected to the outer wall of the reciprocating screw 802. Cleaning brushes 804 are fixed to the side wall of the threaded sleeve 803. Two sets of cleaning brushes 804 are provided, and the two sets of cleaning brushes 804 are symmetrically arranged about the vertical centerline of the protective shell 1. A guide rod 805 passes through the sleeve 803. The upper and lower ends of the guide rod 805 are fixed to the inner wall of the protective shell 1, and the guide rod 805 is slidably connected to the through-hole of the threaded sleeve 803. By setting the guide rod 805, the threaded sleeve 803 can be guided. When the reciprocating screw 802 rotates, the threaded sleeve 803 can move on the reciprocating screw 802, causing the threaded sleeve 803 to drive the cleaning brush 804 to move. The cleaning brush 804 can then move against the dustproof net 4, thereby cleaning the dust adhering to the mesh of the dustproof net 4 and preventing the dustproof net 4 from becoming clogged due to excessive dust.

[0033] The aforementioned control mechanism 9 includes a sleeve 901, a sleeve rod 902, a slide rod 906, a connecting spring 914, a support plate 905, a rotating shaft 908, an arc-shaped slide groove 916, a winding wheel 909, a pull rope 910, a connecting seat 911, a cleaning cloth 912, a rotating sleeve 907, and a transmission spring 913. The sleeve 901 is fixed to the inner wall of the protective shell 1. The sleeve rod 902 is slidably mounted on the inner wall of the sleeve 901. The connecting spring 914 is fixed to the top of the sleeve rod 902, and the top of the connecting spring 914 is fixed to the inner wall of the sleeve 901. The support plate 905 is fixed to the inner wall of the protective shell 1. The rotating sleeve 907 is rotatably mounted on the top of the support plate 905. By setting the support plate 905, the rotating sleeve 907 can be supported. A rotating shaft 908 is rotatably mounted at the bottom, and the rotating shaft 908 passes through the support plate 905. The rotating shaft 908 is rotatably connected to the support plate 905 at the through-hole. An arc-shaped groove 916 is opened on the outer wall of the rotating sleeve 907. A sliding rod 906 is fixed on the outer wall of the sleeve rod 902, and the sliding rod 906 passes through the arc-shaped groove 916. The sliding rod 906 fits against the through-hole of the arc-shaped groove 916. An L-shaped connecting rod 903 is fixed on the outer wall of the sleeve rod 902. A transmission plate 904 is fixed at the end of the L-shaped connecting rod 903 away from the sleeve rod 902. The transmission plate 904 is slidably mounted on the inner wall of the protective shell 1. Two sets of transmission plates 904 are provided, and the two sets of transmission plates 904 are symmetrically arranged with the center line in the vertical direction of the protective shell 1 as the axis of symmetry. Thus, when the reciprocating screw 80 2. The threaded sleeve 803 moves upward. When the threaded sleeve 803 contacts the bottom of the transmission plate 904, it will press against the transmission plate 904. Due to the pressure, the transmission plate 904 will move upward. Through the L-shaped connecting rod 903, the sleeve rod 902 moves upward in the sleeve 901, compressing the connecting spring 914. This will cause the slide rod 906 to slide in the arc-shaped groove 916, which will then drive the rotating sleeve 907 to rotate. The rotating sleeve 907 will then drive the rotating shaft 908 to rotate. The outer wall of the rotating shaft 908 is fixed with a winding wheel 909, which will then drive the winding wheel 909 to rotate. The outer wall of the winding wheel 909 is fixed with a pull rope. 910. A connecting seat 911 is fixed to the end of the pull rope 910 away from the take-up reel 909. A fixing rod 915 passes through the connecting seat 911. Both ends of the fixing rod 915 are fixed to the inner wall of the protective shell 1. The fixing rod 915 guides the connecting seat 911 left and right. A cleaning cloth 912 is fixed to the back of the connecting seat 911. The side of the cleaning cloth 912 away from the connecting seat 911 is in contact with the display module 2. The cleaning cloth 912 cleans the display module 2. A transmission spring 913 is fixed to the side wall of the connecting seat 911. The side of the transmission spring 913 away from the connecting seat 911 is fixed to the inner wall of the protective shell 1. The transmission spring 913 resets the connecting seat 911.Furthermore, when the rotating sleeve 907 rotates, it drives the rotating shaft 908 to rotate, causing the winding wheel 909 to rotate. This allows the winding wheel 909 to wind up the pull rope 910, enabling the pull rope 910 to pull the two sets of connecting seats 911 away from each other. Consequently, the cleaning cloth 912 moves against the display module 2, thus cleaning the display module 2. When the two sets of connecting seats 911 move away from each other, the transmission spring 913 is compressed, and the bottom of the protective shell 1 has a dust discharge trough 10. A sealing plate 11 is slidably installed on the bottom of the protective shell 1, which seals the dust discharge trough 10. A handle 12 is fixed to the bottom of the sealing plate 11. When the handle 12 is pulled to the left... This allows the sealing plate 11 to be removed from the bottom of the ash discharge trough 10, thus enabling cleaning of the inside of the protective shell 1. When the threaded sleeve 803 moves downward on the reciprocating screw 802, it prevents the threaded sleeve 803 from pressing against the transmission plate 904. Because the connecting spring 914 is in a compressed state, the sleeve rod 902 moves downward, causing the slide rod 906 to move downward in the arc-shaped slide groove 916, causing the rotating sleeve 907 to rotate clockwise, which in turn causes the rotating shaft 908 to rotate clockwise, thereby releasing the pull rope 910 from the take-up wheel 909. Because the transmission spring 913 is in a compressed state, the connecting seat 911 and the cleaning cloth 912 can be returned to their original positions via the transmission spring 913, allowing for the next cleaning operation.

[0034] Working principle: When the motor 5 is started, the rotating rod 6 rotates, which in turn drives the fan blade 7 to rotate, thus dissipating heat from the protective shell 1. When the rotating rod 6 rotates, the transmission belt 801 causes the reciprocating screw 802 to rotate. When the reciprocating screw 802 rotates, the threaded sleeve 803 moves on it, causing the threaded sleeve 803 to move and drive the cleaning brush 804. The cleaning brush 804 then moves to adhere to the dustproof net 4, thus cleaning the dustproof net 4. The dust adhering to the mesh is cleaned to prevent excessive dust in the dustproof mesh 4 from causing blockage. When the threaded sleeve 803 moves to contact the bottom of the transmission plate 904, it will press the transmission plate 904. Due to the pressure, the transmission plate 904 will move upward. Through the L-shaped connecting rod 903, the sleeve rod 902 moves upward in the sleeve 901, compressing the connecting spring 914. This will cause the slide rod 906 to slide in the arc-shaped groove 916, thus allowing the slide rod 906 to move. 06 drives the rotating sleeve 907 to rotate, which in turn drives the rotating shaft 908 to rotate. A winding wheel 909 is fixed to the outer wall of the rotating shaft 908, allowing the rotating shaft 908 to drive the winding wheel 909 to rotate. This causes the winding wheel 909 to wind up the pull rope 910, allowing the pull rope 910 to pull the two sets of connecting seats 911 away from each other. This causes the cleaning cloth 912 to move against the display module 2, thus cleaning the display module 2. When the threaded sleeve 803 reciprocates on the screw 80... 2. Moving downwards will cause the threaded sleeve 803 to stop pressing the transmission plate 904. Because the connecting spring 914 is in a compressed state, the sleeve rod 902 moves downwards, driving the slide rod 906 to move downwards in the arc-shaped slide groove 916, causing the rotating sleeve 907 to rotate clockwise, which in turn causes the rotating shaft 908 to rotate clockwise, thereby causing the pull rope 910 to be released from the take-up wheel 909. Because the transmission spring 913 is in a compressed state, the connecting seat 911 and the cleaning cloth 912 can be returned to their original positions through the transmission spring 913, so that the next cleaning operation can be carried out.

[0035] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the scope of protection of the present invention.
