Description

Technical Field

[0001] This application relates to the field of LED display equipment technology, and in particular to an LED display unit and an LED display screen. Background Technology

[0002] During the assembly, handling, transportation, and on-site installation of LED display units, the LED beads attached to the surface of the display module are exposed, making them extremely susceptible to damage and detachment due to scratches or impacts, directly shortening the product's lifespan. Therefore, the industry has widely adopted edge protection mechanisms to protect the edges of the display module during disassembly and handling, and to allow for proper splicing surfaces during installation.

[0003] However, existing edge protection mechanisms often expose the drive components throughout the entire device, allowing operators to manually operate or push them with tools. However, when the enclosure needs to be placed vertically on the ground or on a pallet, the exposed drive components will be in direct contact with the ground. Under its own weight or external stacking pressure, the drive components are easily compressed, accidentally triggering the edge protection mechanism to disengage, causing the lower LED chips to be re-exposed and losing their protective function. This accidental triggering not only reduces reliability during handling but also increases the risk of LED chip damage, affecting the overall screen assembly and disassembly efficiency and customer experience.

[0004] Therefore, there is an urgent need for an LED display unit that can prevent the edge protection mechanism from being accidentally triggered by the ground or other supports, while also ensuring ease of operation. Summary of the Invention

[0005] The purpose of this application is to provide an LED display unit and an LED display screen that can prevent the edge protection mechanism from being accidentally triggered by the ground or other supports, while also ensuring ease of operation.

[0006] To achieve the above objectives, this application provides an LED display unit, including a housing and an LED display module. The first and second sides of the housing are provided with LED display edge protection mechanisms, which are used to protect the LED display module.

[0007] The LED display screen edge protection mechanism includes a protection component and a driver. The driver has a driving surface, which is configured to trigger the driver to drive the protection component to move between a protection position and an avoidance position when subjected to an external force. The driving surface of the driver located on the first or second side of the housing is not higher than the outer surface of the corresponding protection component.

[0008] In some embodiments, the LED display edge protection mechanism further includes a mounting base for connection with the housing;

[0009] The protection component is movably connected to the mounting base, and the drive component is movably connected to both the protection component and the mounting base.

[0010] The fixed base is provided with a first limiting groove, the driving component is provided with a second limiting groove, and the protection component is provided with a first limiting member and a second limiting member. The first limiting member is embedded in the first limiting groove, and the second limiting member is inserted and cooperates with the second limiting groove so that the driving component drives the protection component to switch from the protection position to the avoidance position during the movement.

[0011] In some embodiments, the first limiting groove includes a first horizontal groove and a first inclined groove, and the second limiting groove includes a second horizontal groove and a second inclined groove.

[0012] The driving component has a first motion stage and a second motion stage along a first direction;

[0013] During the first movement phase of the drive component, the first limiting member and the second limiting member slide in the first horizontal groove and the second inclined groove respectively, so that the protection component exits the protection position along the second direction perpendicular to the first direction.

[0014] In the second movement phase of the drive component, the first limiting member and the second limiting member slide in the first inclined groove and the second horizontal groove respectively, so that the protective component moves to the avoidance position along the first direction and the second direction.

[0015] In some embodiments, the fixed base is further provided with a guide structure, the protective component is further provided with a clearance groove, and the driving member passes through the clearance groove and is embedded in the guide structure so that the driving member moves relative to the fixed base in a first direction.

[0016] In some embodiments, a reset elastic element is also included, and the drive member is further provided with a guide post. One end of the reset elastic element is sleeved on the guide post, and the other end abuts against the inner bottom surface of the guide structure. The reset elastic element is used to provide elastic force so that the drive member tends to move away from the inner bottom surface.

[0017] In some embodiments, the protective component includes a movable seat and a protective plate disposed on the movable seat, wherein the dimension of the protective plate along the second direction is larger than the dimension of the movable seat along the second direction;

[0018] When the protective components are in the protected position, the protective plate is configured to extend relative to the LED display module to prevent the LED display module from being impacted.

[0019] When the protective components are in the avoidance position, the protective plate is configured to retract relative to the LED display module to expose the LED display module to be spliced.

[0020] In some embodiments, the fixed base is further provided with a mounting groove, and the movable base is movably installed in the mounting groove. The fixed base includes a fixed plate and two limiting plates. The two limiting plates are located on both sides of the mounting groove along a third direction. The limiting plates are provided with two spaced first limiting grooves. The fixed plate is located on one side of the mounting groove along a second direction. The fixed plate is provided with a connector for connecting to the housing.

[0021] Among them, the third direction is perpendicular to both the first and second directions.

[0022] In some embodiments, the movable seat includes two supports disposed opposite to each other along a second direction, and the supports are respectively provided with first limiting members on both sides along a third direction.

[0023] In some embodiments, the protective component is further provided with a limiting groove, and the driving component is further provided with a limiting protrusion. The limiting protrusion is fitted into the limiting groove so that the protective component is locked in the protective position.

[0024] This application also provides an LED display screen, including at least two LED display units according to any of the above, wherein in any LED display unit, the driving surface on the first side of the housing is not higher than the outer surface of the corresponding protective component, and the driving surface on the second side of the housing is higher than the outer surface of the corresponding protective component. When two adjacent LED display units are spliced ​​together, the two driving surfaces press against each other to trigger the movement of the corresponding driving component.

[0025] Compared to the background technology described above, the LED display unit provided in this application embodiment includes a housing and an LED display module. The first and second sides of the housing are provided with LED display edge protection mechanisms, which are used to protect the LED display module. The LED display edge protection mechanism includes a protection component and a driving component. The driving component has a driving surface, which is configured to trigger the driving component to drive the protection component to move between a protection position and an avoidance position when subjected to an external force. The driving surface on the first or second side of the housing is not higher than the outer surface of the corresponding protection component.

[0026] For example, an upper edge protection mechanism is set at the top of the LED display unit's housing, and a lower edge protection mechanism is set at the bottom. The driving surface of the upper edge protection mechanism protrudes from the outer surface of the protective component, while the driving surface of the lower edge protection mechanism does not protrude from the outer surface of the protective component.

[0027] In this way, since the driving surface of the lower edge protection mechanism does not protrude from the outer surface of the protective component, when the cabinet is placed on the ground, the lower edge protection mechanism will not be accidentally triggered to disengage from the protective position. This avoids the protective component from switching from the protective position to the avoidance position due to the driving surface protruding from the outer surface of the protective component being easily squeezed by the ground. This not only reduces the risk of damage to the LED display module, but also improves the efficiency of the entire screen disassembly and assembly. Attached Figure Description

[0056] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0057] To enable those skilled in the art to better understand the present application, the present application will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0058] Please see Figure 1 and Figure 2 The LED display unit 1 provided in this application embodiment includes a housing 20 and an LED display module 30. The first and second sides of the housing 20 are provided with LED display screen edge protection mechanism 10, which is used to protect the LED display module 30.

[0059] For example, for a specific LED display unit 1 in an LED display screen, its housing 20 has an upper edge protection mechanism at its upper end, such as... Figure 3 As shown; the lower end is equipped with a lower side guard mechanism, such as Figure 10 As shown.

[0060] Furthermore, the LED display edge protection mechanism 10 includes a protection component 200 and a driver 300. The driver 300 has a driving surface 303, which is configured to trigger the driver 300 to drive the protection component 200 to move between a protection position and an avoidance position when subjected to an external force. The driving surface 303 of the driver 300 located on the first or second side of the housing 20 is not higher than the outer surface of the corresponding protection component 200.

[0061] It should be noted that in the protected position, the protective component 200 protrudes from the LED display module 30 along the splicing direction to prevent it from being hit by external collisions; in the avoidance position, the protective component 200 retracts to a position where it does not protrude from the LED display module 30, so that adjacent LED display modules 30 can complete the splicing.

[0062] For example, an upper edge protection mechanism is provided at the upper end of the housing 20 of the LED display unit 1, and a lower edge protection mechanism is provided at the lower end. The driving surface 303 of the upper edge protection mechanism protrudes from the outer surface of the protective component 200, while the driving surface 303 of the lower edge protection mechanism does not protrude from the outer surface of the protective component 200.

[0063] In this way, since the driving surface 303 of the lower edge protection mechanism does not protrude from the outer surface of the protective component 200, when the cabinet 20 is placed on the ground, the lower edge protection mechanism will not be accidentally triggered to disengage from the protective position. This avoids the protective component 200 from switching from the protective position to the avoidance position due to the driving surface 303 protruding from the outer surface of the protective component 200 being easily squeezed by the ground. This not only reduces the risk of damage to the LED display module 30, but also improves the efficiency of the entire screen disassembly and assembly.

[0064] Please see Figure 3 and Figure 10 The LED display screen edge protection mechanism 10 also includes a fixing base 100.

[0065] The mounting base 100 is used to connect to the housing 20 of the LED display unit; the protective component 200 is movably connected to the mounting base 100 and is used to move between a protective position and a clearance position relative to the LED display module 30; the driving component 300 is movably connected to the protective component 200 and the mounting base 100 and is used to drive the protective component 200 to move relative to the mounting base 100.

[0066] Please see Figures 4-7 , Figures 11-14 The fixed base 100 is provided with a first limiting groove 101, the driving member 300 is provided with a second limiting groove 301, and the protective component 200 is provided with a first limiting member 201 and a second limiting member 202. The first limiting member 201 is embedded in the first limiting groove 101, and the second limiting member 202 is inserted and cooperates with the second limiting groove 301 so that the driving member 300 drives the protective component 200 to switch from the protective position to the avoidance position during the movement.

[0067] With this configuration, the first limiting groove 101 and the first limiting member 201 form an auxiliary guide for the movement of the protective component 200. Simultaneously, the second limiting groove 301 and the second limiting member 202 pass through to achieve the transmission connection and auxiliary guidance between the driving member 300 and the protective component 200, thus forming a dual-guide cooperative structure. This eliminates the need for additional connecting rods, levers, or complex hinge structures, reduces the number of parts, and simplifies the assembly relationship. This significantly reduces assembly time and process requirements. Furthermore, the dual-guide structure ensures balanced force distribution and a defined trajectory for the protective component 200, improving stability during movement. This solves the problems of numerous parts, cumbersome assembly steps, and poor operational stability inherent in traditional edge protection mechanisms.

[0068] In some embodiments, the first limiting groove 101 and the second limiting groove 301 can both be configured as a combined groove structure. For example, the limiting groove can be designed as a combination of a horizontal groove and an inclined groove, so that the movement trajectory of the protection component 200 is decomposed into two stages in two-dimensional space.

[0069] In this embodiment, the first limiting groove 101 includes a first horizontal groove 1011 and a first inclined groove 1012, and the second limiting groove 301 includes a second horizontal groove 3011 and a second inclined groove 3012; the driving member 300 has a first movement stage and a second movement stage along a first direction.

[0070] During the first movement phase of the drive member 300, the first limiting member 201 and the second limiting member 202 slide in the first horizontal groove 1011 and the second inclined groove 3012 respectively, so that the protection component 200 exits the protection position along the second direction perpendicular to the first direction.

[0071] During the second movement phase of the drive member 300, the first limiting member 201 and the second limiting member 202 slide in the first inclined groove 1012 and the second horizontal groove 3011 respectively, so that the protection component 200 moves to the avoidance position along the first direction and the second direction.

[0072] It should be noted that the first direction mentioned above can be as follows: Figure 3 The Z-axis direction is shown, and the second direction can be as follows: Figure 3 The X-axis direction is shown.

[0073] In this way, by designing the first limiting groove 101 and the second limiting groove 301 as a combination of horizontal groove and inclined groove respectively, the movement trajectory of the protection component 200 is decomposed into two stages: in the first movement stage, it first moves straight out of the protection position along the second direction; in the second movement stage, it retracts to the avoidance position along the first and second directions to give up the splicing space, realizing two-dimensional composite movement, which not only ensures the sufficiency of avoidance, but also optimizes the compactness of the movement path.

[0074] Please see Figure 2 When splicing or stacking the upper and lower LED display units, the lower edge protection mechanism of the upper LED display unit contacts and presses against the upper edge protection mechanism of the lower LED display unit. In the first movement stage, the first limiting member 201 and the second limiting member 202 slide in the corresponding first horizontal groove 1011 and the second inclined groove 3012, respectively, so that the protective component 200 moves to the right and exits the protective position. As the splicing continues, the second movement stage begins. The first limiting member 201 and the second limiting member 202 slide in the corresponding first inclined groove 1012 and the second horizontal groove 3011, respectively, so that the protective component 200 continues to move to the right and down to the avoidance position. At this time, the protective plate 205 is completely retracted to the rear side of the corresponding LED display module 30, the upper and lower LED display units are spliced, and the LED display screen can be installed and operated normally.

[0075] Please see Figure 4 and Figure 11The fixed base 100 is also provided with a guide structure 102, which can be a guide groove integrally set at the bottom of the fixed base 100. The protective component 200 is also provided with a relief groove 203. The driving member 300 passes through the relief groove 203 and is embedded in the guide structure 102 so that the driving member 300 moves relative to the fixed base 100 in the first direction.

[0076] It can be seen that the guide structure 102 provides stable linear guidance for the drive component 300, while the clearance groove 203 provides space for the relative movement between the drive component 300 and the protection component 200, so that the two do not interfere with each other during the movement, ensuring the reliability of the transmission cooperation.

[0077] In some embodiments, the LED display edge protection mechanism 10 further includes a reset elastic element 400, and the drive element 300 is also provided with a guide post 302. One end of the reset elastic element 400 is sleeved on the guide post 302, and the other end abuts against the inner bottom surface of the guide structure 102. The reset elastic element 400 is used to provide elastic force so that the drive element 300 tends to move away from the inner bottom surface.

[0078] Of course, depending on actual needs, the reset elastic element 400 can be a compression spring. The reset elastic element 400 is used to make the drive element 300 automatically reset when it is not subjected to external force, thereby driving the protection component 200 to automatically return to the protection position, which simplifies the operation steps and improves the ease of use.

[0079] Furthermore, the LED display edge protection mechanism 10 also includes a reset spring 500. One end of the reset spring 500 is connected to the fixed base 100, and the other end is connected to the movable base 204 of the protection component 200. The reset spring 500 provides elastic force to give the protection component 200 a tendency to move from the avoidance position to the protection position. In this way, the protection component 200 can automatically reset when the driving component 300 is not subjected to external force, thereby automatically returning to the protection position. Of course, the reset spring 500 can be a tension spring.

[0080] In some embodiments, the protective component 200 includes a movable seat 204 and a protective plate 205 disposed on the movable seat 204, wherein the dimension of the protective plate 205 along the second direction is larger than the dimension of the movable seat 204 along the second direction.

[0081] As can be seen, the size design of the aforementioned protective plate 205 allows it to completely cover the edge of the LED display module 30 when extended, forming effective circumferential protection; when retracted, it completely leaves the splicing surface of the LED display module 30 unaffected, without affecting the tight fit of adjacent LED display units, thus balancing protection and splicing requirements.

[0082] In this way, when the protection component 200 is in the protected position, the protection plate 205 extends relative to the LED display module 30 to prevent the LED display module 30 from being impacted, thus providing protection. Figure 8 and Figure 15 As shown; when the protective component 200 is in the avoidance position, the protective plate 205 retracts relative to the LED display module 30 to expose the LED display module 30 to be spliced, without affecting the tight bonding of adjacent LED display units, such as... Figure 9 and Figure 16 As shown.

[0083] When splicing two adjacent LED display units, as the splicing progresses, the driving surface 303 of the lower edge protection mechanism of the upper LED display unit comes into contact with the driving surface 303 of the upper edge protection mechanism of the lower LED display unit. The protective plates 205 on both sides continuously retract until the protective plates 205 complete two stages of movement, thus completing the retraction process of the protective plates 205, and the LED display screen can be installed and operated normally. Conversely, when the protective plates 205 are needed, the two adjacent LED display units can be separated. The protective plates 205 will automatically return to their original position under the action of springs, achieving the purpose of protection.

[0084] In some embodiments, the fixed base 100 is further provided with a mounting groove 103, and the movable base 204 is movably installed in the mounting groove 103. The fixed base 100 includes a fixed plate 104 and two limiting plates 105. The two limiting plates 105 are located on both sides of the mounting groove 103 along a third direction. The limiting plates 105 are provided with two spaced first limiting grooves 101. The fixed plate 104 is located on one side of the mounting groove 103 along a second direction. The fixed plate 104 is provided with a connector 106 for connecting with the housing 20.

[0085] It should be noted that the aforementioned third direction is perpendicular to both the first and second directions. The third direction can be as follows: Figure 3 The Y-axis direction is shown.

[0086] The connector 106 on the fixing plate 104 is used to achieve a quick and detachable connection between the LED display edge protection mechanism 10 and the housing 20. The connector 106 includes, but is not limited to, bolts, pins, and other connecting components.

[0087] The design of the two-sided limiting structure forms a guiding space, which restricts the movable seat 204 in the direction perpendicular to the first and second directions, retaining only the degree of freedom of movement along the first and second directions. The structure is compact and the guidance is precise. At the same time, the two-sided limiting plates 105 are symmetrically arranged and cooperate with the spaced first limiting grooves 101 to form a four-point support guiding structure, which makes the protective component 200 symmetrically stressed and run smoothly during movement, effectively suppressing the deflection torque and improving the anti-overturning ability and movement stability.

[0088] In some embodiments, the movable seat 204 includes two supports 2041 disposed opposite to each other along a second direction, and the supports 2041 are respectively provided with first limiting members 201 on both sides along a third direction.

[0089] In this way, the double-sided supports 2041 are symmetrically arranged, and together with the first limiting grooves 101 on both sides of the limiting plate 105, a four-point support and guiding structure is formed, so that the protective component 200 is subjected to symmetrical force and runs smoothly during movement, effectively suppressing the deflection torque and improving the anti-overturning ability and movement stability.

[0090] In some embodiments, the protection component 200 is further provided with a limiting groove 206, and the driving component 300 is further provided with a limiting protrusion 304. The limiting protrusion 304 is embedded in the limiting groove 206 so that the protection component 200 is locked in the protection position.

[0091] It can be seen that the engagement of the limiting protrusion 304 and the limiting groove 206 provides mechanical locking for the protection position, preventing the protection component 200 from slipping off by itself due to transportation vibration or accidental collision, and further improving the reliability of protection.

[0092] When splicing or stacking the lower LED display unit with the upper LED display unit in the protected position of the edge protection mechanism, first disengage the limiting protrusion 304 from the corresponding limiting groove 206 to unlock it, and then switch from the protected position to the avoidance position.

[0093] In some embodiments, the first limiting member 201 and the second limiting member 202 are both cylindrical pins. The outer diameter of the first limiting member 201 is in clearance fit with the groove width of the first limiting groove 101, and the outer diameter of the second limiting member 202 is in clearance fit with the groove width of the second limiting groove 301.

[0094] The cylindrical pin is a standard part, and the clearance fit ensures smooth relative sliding while allowing for machining tolerances and assembly errors, thus reducing manufacturing difficulty and cost.

[0095] The working principle is explained below using an example where the upper edge protection mechanism is provided at the top of the LED display unit housing 20, and the lower edge protection mechanism is provided at the bottom. The driving surface 303 of the upper edge protection mechanism protrudes from the outer surface of the protective plate 205, while the driving surface 303 of the lower edge protection mechanism is lower than the outer surface of the protective plate 205 or flush with both.

[0096] First, the lower LED display unit with the edge protection mechanism in the protected position is spliced ​​or stacked with the upper LED display unit. The driving surface 303 of the lower edge protection mechanism of the upper LED display unit and the driving surface 303 of the upper edge protection mechanism of the lower LED display unit begin to press and contact each other, so that the limiting protrusion 304 in the upper and lower edge protection mechanisms are disengaged from the corresponding limiting groove 206, thereby releasing the locking state of the edge protection mechanism.

[0097] Then, the driving surface 303 of the lower edge protection mechanism of the upper LED display unit continues to press against the driving surface 303 of the upper edge protection mechanism of the lower LED display unit, and the first limiting member 201 and the second limiting member 202 slide in the corresponding first horizontal groove 1011 and the second inclined groove 3012 respectively, so that the protection component 200 exits the protection position in the second direction.

[0098] Finally, the driving surface 303 of the lower edge protection mechanism of the upper LED display unit and the driving surface 303 of the upper edge protection mechanism of the lower LED display unit continue to press against each other. The first limiting member 201 and the second limiting member 202 slide in the corresponding first inclined groove 1012 and the second horizontal groove 3011, respectively, so that the protective component 200 moves to the avoidance position along the first direction and the second direction. At this time, the protective plate 205 is completely retracted to the rear side of the corresponding LED display module 30. The LED display module 30 of the upper LED display unit and the LED display module 30 of the lower LED display unit are spliced ​​together, and the LED display screen can be installed and operated normally.

[0099] In other words, when splicing two adjacent LED display units, as the splicing progresses, the driving surface 303 of the lower edge protection mechanism of the upper LED display unit comes into contact with the driving surface 303 of the upper edge protection mechanism of the lower LED display unit, and the protective plates 205 on both sides continue to retract until the protective plates 205 complete the two-stage movement, and the retraction process of the protective plates 205 is completed, and the LED display screen can be installed and operated normally.

[0100] When it is necessary to separate the LED display module 30 of the upper LED display unit from the LED display module 30 of the lower LED display unit, no manual assistance is required. Under the action of the reset elastic element 400, the protection plate 205 can be automatically returned to the protection position. Furthermore, the locking state of the edge protection mechanism is ensured by the locking action of the limiting protrusion 304 and the corresponding limiting groove 206.

[0101] By adopting the aforementioned LED display screen edge protection mechanism 10, a significant amount of manpower is saved in the process of achieving protection, greatly improving the protection efficiency of the single screen cabinet 20. At the same time, the edge protection mechanism has fewer overall parts, is simple to assemble, has obvious cost advantages, and is more competitive in the LED market.

[0102] The LED display screen 1000 provided in this application includes at least two LED display units 1 as described in the above specific embodiments; wherein, in any LED display unit 1, the driving surface 303 at the lower end of the housing 20 is not higher than the outer surface of the corresponding protective component 200, and the driving surface 303 at the upper end of the housing 20 is higher than the outer surface of the corresponding protective component 200.

[0103] In this way, when two adjacent LED display units 1 are spliced ​​together, the two driving surfaces 303 press against each other to trigger the movement of the corresponding driving component 300.

[0104] Specifically, when splicing two adjacent LED display units 1, as the splicing progresses, the driving surface 303 of the lower edge protection mechanism of the upper LED display unit 1 comes into contact with the driving surface 303 of the upper edge protection mechanism of the lower LED display unit 1, and the protective plates 205 on both sides continue to retract until the protective plates 205 complete the two-stage movement, and the retraction process of the protective plates 205 is completed, and the LED display screen can be installed and operated normally.

[0105] When protection by the protection board 205 is required, simply separate the two adjacent LED display units 1. The protection board 205 will automatically return to its original position under the action of the spring, thus achieving the purpose of protection.

[0106] It should be noted that in this specification, relational terms such as first and second are used only to distinguish one entity from several other entities, and do not necessarily require or imply any such actual relationship or order between these entities.
