Description

Technical Field

[0001] This application relates to the field of LED display technology, and in particular to a display module. Background Technology

[0002] Display modules use light-emitting diodes (LEDs) arranged in sequence to display images. They are characterized by high brightness, wide viewing angles, and long lifespan, making them widely used in products such as outdoor advertising screens. A display module typically includes a housing and a handle. The handle, located on the housing, allows the entire display module to be lifted, facilitating its movement. However, traditional display modules are either expensive to manufacture or have handles that easily detach from the housing, resulting in a trade-off between low cost and high reliability. Utility Model Content

[0003] One of the technical problems addressed by this application is how to improve the reliability of display modules while reducing costs.

[0004] A display module, comprising:

[0005] The housing, wherein a locking hole is provided on the housing; and

[0006] The handle includes a lifting part, a rotating part, and a protruding part. The rotating part protrudes from the lifting part and is used to rotatably engage with the locking hole. The protruding part protrudes radially from the rotating part and is able to abut against the inner wall surface of the locking hole along the axial direction of the rotating part so that the rotating part is always engaged with the locking hole.

[0007] In one embodiment, the rotating part has a free end disposed away from the lifting part, and the protrusion protrudes from the outer peripheral surface of the rotating part and is disposed close to the free end.

[0008] In one embodiment, the protrusion extends circumferentially along the rotating portion at an angle of less than 360° and is in an open-ring shape.

[0009] In one embodiment, the protrusion has an inner side, an outer side, and a top surface. One end of the inner side and the outer side are connected to the outer peripheral surface of the rotating part. The top surface is connected to the other end of the inner side and the outer side. The outer side is disposed away from the lifting part, and the inner side is disposed towards the lifting part and abuts against the inner wall surface of the card hole along the axial direction of the rotating part. The inner side is perpendicular to the axis around which the rotating part rotates, and the top surface is parallel to the axis around which the rotating part rotates.

[0010] In one embodiment, the outer side surface is set at an acute angle to the axis around which the rotating part rotates, and the distance between the outer side surface and the rotating part decreases from the end of the outer side surface connected to the rotating part to the end of the outer side surface connected to the top surface.

[0011] In one embodiment, the outer surface includes a first connecting segment and a second connecting segment. The first connecting segment is connected to the rotating part, and the second connecting segment is connected to the first connecting segment and the top surface. The first connecting segment is an arc surface, and the second connecting segment is a plane.

[0012] In one embodiment, the lifting part is provided with an arc surface near the rotating part, the central axis of the cylindrical surface on which the arc surface is located coincides with the axis around which the rotating part rotates, and a plurality of grooves are recessed on the arc surface and extend a certain length along the axial direction of the rotating part, and the plurality of grooves are spaced apart along the circumference of the rotating part.

[0013] In one embodiment, the lifting portion includes a first lifting section and two second lifting sections, the two second lifting sections are spaced apart along the axial direction of the rotating portion, and each of the two second lifting sections is provided with an end of the rotating portion, and the first lifting section is connected to the end of the second lifting section away from the rotating portion.

[0014] In one embodiment, the housing includes a bottom shell and a mounting platform, the mounting platform protruding from the bottom shell and forming a first hole segment and a second hole segment configured as the locking hole. The diameter of the first hole segment is smaller than the diameter of the second hole segment. The inner wall surface of the locking hole includes a stepped surface located at the junction of the first hole segment and the second hole segment. The stepped surface extends radially along the rotating part, which passes through the first hole segment and the second hole segment. The protrusion is located in the second hole segment and can abut against the stepped surface.

[0015] In one embodiment, at least one of the following schemes is also included:

[0016] The housing includes a bottom shell and a limiting post. The limiting post protrudes along the axial direction of the rotating part and is disposed on the bottom shell. The rotating part is provided with a plurality of grooves that can cooperate with the limiting post during rotation.

[0017] The housing has a clearance hole. When the lifting part is stacked on the housing, the lifting part covers part of the clearance hole.

[0018] One technical advantage of one embodiment of this application is that, given the protrusion on the rotating part, the protrusion can abut against the inner wall surface of the locking hole along the axial direction of the rotating part, ensuring that the rotating part is always engaged with the locking hole. This simplifies the structure of the handle and the assembly process between the handle and the housing, thereby reducing the manufacturing cost of the display module. Furthermore, it prevents the handle from detaching from the housing, effectively avoiding damage to the housing or even personal safety caused by the handle falling off, thus improving the reliability of the display module.

Detailed Implementation

[0026] To make the above-mentioned objectives, features, and advantages of this application more apparent and understandable, the specific embodiments of this application are described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of this application. However, this application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this application. Therefore, this application is not limited to the specific embodiments disclosed below.

[0027] In the description of this application, it should be understood that if terms such as "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential" appear, these terms indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.

[0028] Furthermore, where the terms "first" and "second" appear, these terms are for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined with "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this application, where the term "multiple" appears, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0029] In this application, unless otherwise expressly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise expressly limited. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0030] In this application, unless otherwise expressly specified and limited, the use of descriptions such as "above" or "below" the second feature indicates that the first and second features are in direct contact or indirect contact via an intermediate medium. Furthermore, "above," "on top of," and "over" the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply that the first feature is at a higher horizontal level than the second feature. Similarly, "below," "below," and "under" the second feature can mean that the first feature is directly below or diagonally below the second feature, or simply that the first feature is at a lower horizontal level than the second feature.

[0031] It should be noted that if an element is referred to as being "fixed to" or "set on" another element, it can be directly on the other element or there may be an intervening element. If an element is considered to be "connected to" another element, it can be directly connected to the other element or there may be an intervening element. If so, the terms "vertical," "horizontal," "upper," "lower," "left," "right," and similar expressions used in this application are for illustrative purposes only and do not represent the only possible implementation.

[0032] See Figure 1 , Figure 2 and Figure 3 According to one embodiment of this application, a display module 10 includes a housing 100 and a handle 200. The housing 100 has a locking hole 123. The handle 200 includes a lifting portion 210, a rotating portion 220, and a protruding portion 230. The rotating portion 220 protrudes from the lifting portion 210 and is used to rotatably engage with the locking hole 123. The protruding portion 230 protrudes radially from the outer circumferential surface of the rotating portion 220 and can abut against the inner wall surface of the locking hole 123 along the axial direction of the rotating portion 220, ensuring that the rotating portion 220 is always engaged with the locking hole 123. Therefore, when the rotating portion 220 engages with the locking hole 123, the abutment of the protruding portion 230 against the inner wall surface of the locking hole 123 along the axial direction of the rotating portion 220 prevents the rotating portion 220 from disengaging from the locking hole 123, thereby ensuring the stability and reliability of the connection between the handle 200 and the housing 100.

[0033] For traditional handles, if additional locking components are used to limit the handle's movement, preventing it from disengaging from the locking hole, this would require additional locking components, making the display module structure more complex and the assembly process more complicated, thus increasing the manufacturing cost. Conversely, without locking components, the handle can easily detach from the housing. If the handle falls off during the process of lifting the entire display module, it could damage the housing or even endanger personal safety, thus affecting the reliability of the display module.

[0034] In the above embodiment, the display module 10 has a protrusion 230 provided in the rotating part 220, which abuts against the inner wall of the slot 123 along the axial direction of the rotating part 220, so that the rotating part 220 is always engaged with the slot 123. This makes the handle 200 structurally simpler and simplifies the assembly process between the handle 200 and the housing 100, thereby reducing the manufacturing cost of the display module 10. On the other hand, it prevents the handle 200 from detaching from the housing 100, thus effectively avoiding damage to the housing 100 or even personal safety due to the handle 200 detaching from the housing 100, thereby improving the reliability of the display module 10.

[0035] See Figure 2 , Figure 3 and Figure 4 In some embodiments, the housing 100 includes a bottom shell 110 and a mounting platform 120. The mounting platform 120 protrudes from the bottom shell 110 along its thickness direction and forms a first hole segment 121 and a second hole segment 122. The first hole segment 121 and the second hole segment 122 are configured as a locking hole 123, that is, the locking hole 123 includes the first hole segment 121 and the second hole segment 122. The diameter of the first hole segment 121 is smaller than the diameter of the second hole segment 122. The inner wall surface of the locking hole 123 includes a stepped surface 124, which extends radially along the rotating part 220 and is located at the junction of the first hole segment 121 and the second hole segment 122. The rotating part 220 passes through the first hole segment 121 and the second hole segment 122, and a protrusion 230 is located in the second hole segment 122, which can abut against the stepped surface 124. By abutting against the stepped surface 124, the protrusion 230 cannot enter the first hole 121 from the second hole 122, thus preventing the entire handle 200 from disengaging from the locking hole 123. This ensures the reliability of the display module 10. During the assembly of the handle 200 and the housing 100, pressure can be applied along the axial direction of the rotating part 220, causing the protrusion 230 to enter the second hole 122 from the first hole 121. Obviously, once the protrusion 230 enters the second hole 122, the step surface 124 prevents it from returning to the first hole 121, effectively preventing the handle 200 from disengaging from the locking hole 123 and ensuring the reliability of the display module 10. Meanwhile, the handle 200 can be assembled simply by applying pressure to insert the protrusion 230 from the first hole 121 into the second hole 122, without the need for additional locking parts, thereby simplifying the assembly process of the display module 10 and ultimately reducing the manufacturing cost of the display module 10.

[0036] See Figure 2 , Figure 3 and Figure 4 In some embodiments, the rotating part 220 has a free end located away from the lifting part 210, and the protrusion 230 protrudes from the outer peripheral surface of the rotating part 220 and is located close to the free end, which facilitates the optimization of the structural design of the handle 200. The protrusion 230 extends at a certain angle along the circumference of the rotating part 220, and the angle of extension of the protrusion 230 is less than 360°, making the protrusion 230 open-ring, or roughly arc-shaped. By making the protrusion 230 open-ring, the shape of the slot 123 can be adapted to the protrusion 230, reducing the resistance of the protrusion 230 entering from the first hole segment 121 into the second hole segment 122, thereby improving the assembly efficiency between the handle 200 and the housing 100, and ultimately reducing the manufacturing cost of the entire display module 10.

[0037] See Figure 2 , Figure 3 and Figure 4 In some embodiments, the protrusion 230 has an inner side 231, an outer side 232, and a top surface 233. One end of the inner side 231 and the outer side 232 are respectively connected to the outer peripheral surface of the rotating part 220, and the top surface 233 is connected to the other end of the inner side 231 and the outer side 232, such that the top surface 233 is spaced apart from the outer peripheral surface of the rotating part 220 along the radial direction of the rotating part 220, and the top surface 233 is parallel to the axis around which the rotating part 220 rotates. The outer side 232 and the inner side 231 are spaced apart along the axial direction of the rotating part 220, and the outer side 232 and the inner side 231 face opposite directions, with the outer side 232 facing away from the lifting part 210 and the inner side 231 facing the lifting part 210. The inner surface 231 can abut against the stepped surface 124 in the slot 123, thus preventing the protrusion 230 from entering the first slot 121 from the second slot 122, thereby ensuring that the handle 200 cannot detach from the mounting platform 120. The inner surface 231 is perpendicular to the axis around which the rotating part 220 rotates, so when the inner surface 231 abuts against the stepped surface 124, it further prevents the protrusion 230 from entering the first slot 121 from the second slot 122, thereby further improving the reliability of the display module 10.

[0038] See Figure 2 , Figure 3 and Figure 4In some embodiments, the outer surface 232 is set at an acute angle to the axis around which the rotating part 220 rotates, and the distance between the outer surface 232 and the rotating part 220 decreases from the end connected to the outer surface 232 to the end connected to the top surface 233. This makes the outer surface 232 have an inclined wedge shape. During the process of the protrusion 230 entering the first hole section 121, the outer surface 232 contacts the mounting platform 120 first. Since the outer surface 232 has an inclined wedge shape, it can play a certain guiding role, thereby reducing the resistance of the protrusion 230 entering the first hole section 121 and ensuring that the handle 200 is smoothly inserted into the locking hole 123, thereby improving the assembly efficiency between the handle 200 and the housing 100, and also reducing the manufacturing cost of the display module 10.

[0039] See Figure 2 , Figure 3 and Figure 4 In some embodiments, the outer surface 232 includes an outer first connecting segment 2321 and a second connecting segment 2322. The outer first connecting segment 2321 is connected to the rotating part 220, and the second connecting segment 2322 is connected to the outer first connecting segment 2321 and the top surface 233. The outer first connecting segment 2321 is an arc surface, and the second connecting segment 2322 is a plane. By setting the outer first connecting segment 2321 as an arc surface and the second connecting segment 2322 as a plane, the resistance of the protrusion 230 entering the first hole segment 121 can be further reduced, thereby improving the assembly efficiency between the handle 200 and the housing 100 and reducing the manufacturing cost of the display module 10.

[0040] See Figure 2 , Figure 3 and Figure 4 In some embodiments, the lifting part 210 is provided with an arc surface near the rotating part 220. The central axis of the cylindrical surface on which the arc surface is located coincides with the axis around which the rotating part 220 rotates. Multiple grooves 2121 are recessed on the arc surface, extending a certain length along the axial direction of the rotating part 220. The multiple grooves 2121 are spaced apart circumferentially around the rotating part 220. The housing 100 also includes a limiting post 130, which protrudes axially from the rotating part 220 onto the bottom housing 110 and can engage with the grooves 2121. During the rotation of the lifting part relative to the locking hole 123, different grooves 2121 will engage with the limiting post 130. When the limiting post 130 engages with the groove 2121, the limiting post 130 can provide a certain resistance to the rotation of the handle 200. When the driving force of the handle 200 is less than this resistance, the handle 200 will not be able to rotate relative to the housing 100, thereby causing the handle 200 to remain at a position that maintains a certain angle with the housing 100.

[0041] See Figure 1 , Figure 5 and Figure 6 For example, the handle 200 can maintain an angle relationship of 0°, 45°, 90°, 135°, and 180° with the housing 100, which can be simply understood as the handle 200 having multiple positions during rotation. At the same time, at the moment the limiting post 130 engages with the groove 2121, the limiting post 130 will produce a clicking sound with the lifting part 210. The user can judge from this clicking sound that the handle 200 has rotated to the designated position relative to the housing 100. Therefore, through the engagement of the limiting post 130 and the groove 2121, the handle 200 has position feedback and angle positioning functions during rotation.

[0042] See Figure 2 , Figure 3 and Figure 4 In some embodiments, the lifting portion 210 includes a first lifting section 211 and a second lifting section 212. A groove 2121 is disposed in the second lifting section 212. There are two second lifting sections 212, which are spaced apart along the axial direction of the rotating portion 220. Each of the two second lifting sections 212 has an end of the rotating portion 220 disposed thereon. The rotating portion 220 is located outside the gap between the two second lifting sections 212. The first lifting section 211 is connected to the end of the second lifting section 212 away from the rotating portion 220. Obviously, the number of rotating portions 220 and mounting platforms 120 is equal and corresponds one-to-one, that is, the number of rotating portions 220 and locking holes 123 is equal and corresponds one-to-one. When there are two rotating portions 220, there are also two locking holes 123. By configuring the lifting portion 210 with the above structure, it is easier for the user to hold the handle 200, thereby improving the convenience of operating the handle 200.

[0043] See Figure 2 , Figure 3 and Figure 4 In some embodiments, the housing 100 has a clearance hole 111. When the lifting part 210 is stacked on the housing 100, the lifting part 210 covers part of the clearance hole 111. There are two clearance holes 111, which correspond to the positions of the handle 200 at 0° and 180°, respectively. That is, when the handle 200 is at the positions of 0° and 180° relative to the bottom housing 110, the lifting part 210 will be stacked in the bottom housing 110. Since the lifting part 210 covers part of the clearance hole 111, when it is necessary to rotate the handle 200, the user's fingers can enter the portion of the clearance hole 111 exposed outside the lifting part 210, thereby facilitating the user to apply force to the handle 200 to drive the handle 200 to rotate, which also improves the ease of operation of the handle 200.

[0044] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0045] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
