Description

Technical Field

[0001] This application relates to the technical field of electronic devices, specifically to display stands, display devices, connection structures, and fasteners. Background Technology

[0002] With the increasing prevalence of electronic devices, they have become indispensable social and entertainment tools in people's daily lives, and people's demands for these devices are also rising. Headphones and smart glasses, for example, are widely used in daily life. They can be used in conjunction with mobile phones, computers, and other terminal devices to provide users with an auditory feast. These devices can be displayed and sold in shopping malls, specialty stores, and exhibitions, where display devices are typically set up to promote and showcase related products to attract users to experience them. For these display devices, the display stands used to display the exhibits may include a first and a second display frame connected by fasteners. Problems arise such as fasteners being difficult for assemblers to tighten with their fingers, and fasteners being tightened too far in the first display frame. Summary of the Invention

[0003] This application provides a display stand, which includes a first display frame, a second display frame, and fasteners. The first display frame includes a first base plate, a first side plate and a boss connected to the first base plate. The boss and the first side plate are located on the same side of the first base plate. The boss has a first through hole section and a second through hole section, as well as a third through hole section connecting the first through hole section and the second through hole section. The second through hole section is farther away from the first base plate than the first through hole section. The third through hole section has the smallest diameter among the first through hole section, the second through hole section and the third through hole section. The fastener includes a head, a smooth rod section connected to the head, and a threaded section connected to the smooth rod section. The diameter of the threaded section is larger than the inner diameter of the third through hole section and smaller than the smaller of the diameter of the first through hole section and the diameter of the second through hole section. The fastener passes through the second through hole section, the third through hole section and the first through hole section, and is threadedly connected to the second display frame through the threaded section.

[0004] In some implementations, the ratio between the depth of the third through-hole section and the length of the threaded portion is between 0.6 and 1.

[0005] In some embodiments, the polished rod portion includes a first polished rod segment and a second polished rod segment, the first polished rod segment being closer to the threaded portion than the second polished rod segment, the diameter of the first polished rod segment being smaller than the diameter of the second polished rod segment, and the diameter of the second polished rod segment being larger than the inner diameter of the third through hole segment.

[0006] In some embodiments, the ratio between the inner diameter of the second through-hole section and the diameter of the second smooth rod section is between 0.2 and 0.4.

[0007] In some embodiments, the ratio between the length of the first smooth rod segment and the sum of the depths of the first through-hole segment and the third through-hole segment is between 1 and 1.5.

[0008] In some embodiments, the depth of the first through-hole section is greater than or equal to the length of the threaded portion, and the depth of the second through-hole section is greater than or equal to the length of the second smooth rod section.

[0009] In some embodiments, the ratio between the height of the boss and the height of the first side plate is between 0.7 and 1, and the minimum distance between the boss and the first side plate is between 10 mm and 12 mm.

[0010] In some implementations, the depth of the third through-hole section is between 2 mm and 4 mm.

[0011] In some embodiments, the second display stand includes a second base plate and a second side plate connected to the second base plate, with a boss disposed in the area where the first base plate and the second side plate overlap, and fasteners causing the first base plate to abut against the second side plate.

[0012] In some embodiments, the first display stand includes a partition connected to a first base plate, which divides the first accommodating space formed by the first side plate and the first base plate into a first sub-accommodating area and a second sub-accommodating area. The volume of the first sub-accommodating area is smaller than the volume of the second sub-accommodating area. A boss is located in the first sub-accommodating area and is connected to the first side plate and the partition respectively by reinforcing ribs.

[0013] In some embodiments, a first side plate and a first bottom plate enclose a first accommodating space, and a second side plate and a second bottom plate enclose a second accommodating space. There are multiple bosses, and multiple pairs of through holes are provided in the overlapping area of ​​the first bottom plate and the second side plate. The multiple pairs of through holes and multiple bosses are alternately arranged, and each pair of through holes enables the first accommodating space to communicate with the second accommodating space.

[0014] In some embodiments, the display stand includes a light strip and a wire connected to the light strip in a first display frame, and a main control circuit board, a power switch and an adapter socket in a second display frame. An adapter plug is provided at the end of the wire away from the light strip. The power switch is connected to the main control circuit board and exposed through a through hole. The adapter socket is connected to the main control circuit board and exposed through another through hole. The adapter plug is plugged into the adapter socket. The light emitted by the light strip can pass through the light-transmitting area of ​​the first base plate.

[0015] In some embodiments, the display stand includes a main control circuit board disposed within a second display rack. The side of the second base plate opposite to the second side plate is divided into a first display area and a second display area. The display stand includes a window located in the first display area and detachably connected to the second base plate. The window is used to display a first exhibit that cannot be experienced by the user, so that the window and the first exhibit can be used as a replaceable module. The second display area is used to display a second exhibit that can be experienced by the user. The second exhibit is connected to the main control circuit board via wires.

[0016] This application provides a display device, which includes a display object, wires, and a display platform as described in the above embodiments. The display platform is equipped with a main control circuit board, and the display object can be experienced by users and is connected to the main control circuit board through wires.

[0017] In some implementations, the main control circuit board is provided with a socket terminal, and one end of the wire is provided with a plug terminal, which is connected to the socket terminal to allow the object to be displayed, the wire and the plug terminal to be used as a replaceable module.

[0018] In some implementations, the object shown is an earphone, with the cable arranged in a Y-shape to connect two earphones.

[0019] In some embodiments, the wire includes a first conductive core and a second conductive core that are electrically insulated from each other, and an elastic coating covering the first and second conductive cores. The main control circuit board transmits signals to the object being displayed through the first and second conductive cores. The elasticity of the elastic coating is better than that of either the first or second conductive core, so as to allow the wire to unwind under the rebound of the elastic coating after being wound. In this embodiment, a wire of length L1 is wound twice with a diameter of 10cm and left to stand for 24 hours. The distance between the two ends of the unwound wire is measured as L2, and L2 / L1≥0.6.

[0020] This application provides a connection structure including a first component to be connected, a second component to be connected, and a fastener. The first component to be connected has a first through-hole section, a second through-hole section, and a third through-hole section connecting the first and second through-hole sections. The third through-hole section has the smallest diameter among the first, second, and third through-hole sections. The fastener includes a head, a smooth rod connected to the head, and a threaded part connected to the smooth rod. The diameter of the threaded part is larger than the inner diameter of the third through-hole section and smaller than the smaller of the diameters of the first and second through-hole sections. The fastener passes through the second, third, and first through-hole sections and is threadedly connected to the second component to be connected via the threaded part.

[0021] In some embodiments, the polished rod portion includes a first polished rod segment and a second polished rod segment, the first polished rod segment being closer to the threaded portion than the second polished rod segment, the diameter of the first polished rod segment being smaller than the diameter of the second polished rod segment, and the diameter of the second polished rod segment being larger than the inner diameter of the third through hole segment.

[0022] This application provides a fastener for connecting at least two components to be connected. Any one of the components has a first through-hole section, a second through-hole section, and a third through-hole section connecting the first and second through-hole sections. The third through-hole section has the smallest diameter among the first, second, and third through-hole sections. The fastener includes a head, a smooth rod portion connected to the head, and a threaded portion connected to the smooth rod portion. The smooth rod portion includes a first smooth rod section and a second smooth rod section. The first smooth rod section is closer to the threaded portion than the second smooth rod section. The diameter of the threaded portion is larger than the inner diameter of the third through-hole section and smaller than the smaller of the diameters of the first and second through-hole sections. The fastener passes through the second, third, and first through-hole sections and is threadedly connected to another component to be connected via the threaded portion.

[0023] The beneficial effects of this application are as follows: In the display stand provided by this application, since the boss of the first display stand has a first through hole section, a second through hole section, and a third through hole section connecting the first and second through hole sections, i.e., a three-section through hole, the height of the boss relative to the bottom plate of the first display stand can be higher. This helps to shorten the height difference between the boss and the side plate of the first display stand, thereby preventing the head of the fastener from sinking too deep into the first display stand after the fastener passes through the boss and before connecting the first and second display stands. This helps to reduce the risk of the assembly personnel's fingers being interfered with by the side plate, allowing the assembly personnel to fix the first and second display stands together by tightening the fastener with their fingers; since the diameter of the threaded part of the fastener is larger than the first through hole section, the first through hole section is larger than the second through hole section. The inner diameter of the three-way hole section is smaller than the smaller of the diameter of the first through hole section and the diameter of the second through hole section. This not only allows the fastener to tap its own thread in the third through hole section when it is inserted into the boss, thus shortening the tapping distance, but also allows the third through hole section to be pre-threaded, which also helps to shorten the distance of tightening the fastener. This helps to reduce the difficulty of assembling the fastener with the first display stand. Furthermore, it makes it difficult for the fastener to detach from the first display stand after it is inserted into the boss, which helps to reduce the risk of the fastener falling or being lost. It also allows the threaded part to be at least partially accommodated in the first through hole section, so that the first and second display stands can be as close as possible before being fixed together by the fastener, which helps to reduce the difficulty of assembling the display stand.

[0039] The present application will now be described in further detail with reference to the accompanying drawings and embodiments. It should be noted that the following embodiments are for illustrative purposes only and do not limit the scope of the application. Similarly, the following embodiments are only some, not all, embodiments of the present application, and all other embodiments obtained by those skilled in the art without inventive effort are within the scope of protection of the present application.

[0040] The reference to "embodiment" in this application means that a specific feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this application. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described in this application can be combined with other embodiments.

[0041] As an example, combined Figures 1 to 3 The display device 100 may include a display stand 10, an object 21 displayed on the display stand 10, and a cable 30 connecting the object 21 and the display stand 10. The object 21 can be experienced by the user, for example, by the user wearing the object 21. Furthermore, a main control circuit board 111 may be installed within the display stand 10, and the object 21 can be connected to the main control circuit board 111 via the cable 30, allowing the display stand 10 to transmit signals to the object 21 through the cable 30, thereby facilitating the user experience of the object 21. Based on this, the object 21 can be an electronic device with audio playback capabilities, such as headphones or smart glasses. With this setup, when users experience the displayed item 21, they can control it to play audio files pre-stored in the display device 100 using the preset play / pause, next track, volume down, and volume up buttons 40 on the display stand 10. This eliminates the need for users to connect their own devices, such as mobile phones, making it simple, convenient, and improving user experience with the displayed item 21. It is worth noting that when the displayed item 21 is a pair of headphones, the charging case sold with the headphones can also be displayed.

[0042] As an example, combined Figures 1 to 6The display stand 10 may include a display frame 12, a display frame 13, and fasteners 14, which allow the display frame 12 and the display frame 13 to be detachably fixed together. The display frame 12 may include a base plate 121, a side plate 122 connected to the base plate 121, and a boss 123. The boss 123 and the side plate 122 are located on the same side of the base plate 121. Furthermore, the boss 123 may have a first through-hole section 1231, a second through-hole section 1232, and a third through-hole section 1233 connecting the first through-hole section 1231 and the second through-hole section 1232. The second through-hole section 1232 may be further away from the base plate 121 than the first through-hole section 1231. Among the first through-hole section 1231, the second through-hole section 1232, and the third through-hole section 1233, the third through-hole section 1233 has the smallest diameter. Accordingly, the fastener 14 may include a head 141, a smooth rod portion 142 connected to the head 141, and a threaded portion 143 connected to the smooth rod portion 142. The diameter of the threaded portion 143 is larger than the inner diameter of the third through-hole section 1233 and smaller than the smaller of the diameter of the first through-hole section 1231 and the diameter of the second through-hole section 1232. The fastener 14 passes through the second through-hole section 1232, the third through-hole section 1233, and the first through-hole section 1231, and is threadedly connected to the display frame 13 via the threaded portion 143. With this configuration, since the boss 123 has a first through hole section 1231, a second through hole section 1232, and a third through hole section 1233 connecting the first through hole section 1231 and the second through hole section 1232, i.e., a three-section through hole, the boss 123 can be higher relative to the base plate 121. This helps to shorten the height difference between the boss 123 and the side plate 122, thus preventing the head 141 from sinking too deep into the display frame 12 after the fastener 14 passes through the boss 123 and before connecting the display frame 12 and the display frame 13. This reduces the risk of the assembly personnel's fingers being interfered with by the side plate 122, allowing the assembly personnel to fix the display frame 12 and the display frame 13 together by tightening the fastener 14 with their fingers. Since the diameter of the threaded portion 143 is larger than the inner diameter of the third through hole section 1233 and smaller than the diameter of the first through hole section 1231 and the third through hole section 1232, the boss 1233 can be higher relative to the base plate 121. This helps to shorten the height difference between the boss 123 and the side plate 122. The smaller of the two through-hole sections 1232 not only allows the fastener 14 to tap its own thread in the third through-hole section 1233 during the process of passing through the boss 123, thus shortening the tapping distance and reducing the difficulty of assembling the fastener 14 with the display stand 12, but also allows the third through-hole section 1233 to be pre-threaded, which also helps to shorten the distance of tightening the fastener 14, thereby reducing the difficulty of assembling the fastener 14 with the display stand 12. Furthermore, it makes it difficult for the fastener 14 to detach from the display stand 12 after passing through the boss 123, thus reducing the risk of the fastener 14 falling or being lost. It also allows the threaded portion 143 to be at least partially accommodated in the first through-hole section 1231, allowing the display stand 12 and the display stand 13 to be as close as possible before being fixed together by the fastener 14, thus reducing the difficulty of assembling the display stand 10.

[0043] In some embodiments, the ratio between the depth of the third through hole 1233 and the length of the threaded portion 143 can be between 0.6 and 1. If the ratio is too small, the fastener 14 may be difficult to stop from detaching from the display frame 12 after passing through the boss 123 by the third through hole 1233; if the ratio is too large, the tapping distance may be too large, making it difficult to assemble the fastener 14 and the display frame 12.

[0044] In some embodiments, the smooth rod portion 142 may include a first smooth rod segment 1421 and a second smooth rod segment 1422, with the first smooth rod segment 1421 being closer to the threaded portion 143 than the second smooth rod segment 1422. The diameter of the first smooth rod segment 1421 is smaller than the diameter of the second smooth rod segment 1422, and the diameter of the second smooth rod segment 1422 is larger than the inner diameter of the third through-hole segment 1233. This arrangement, because the second smooth rod segment 1422 is thicker than the first smooth rod segment 1421, helps to reduce the gap between the smooth rod portion 142 and the third through-hole segment 1233, thereby reducing the amplitude of the fastener 14's wobble within the boss 123 and increasing the coaxiality between the fastener 14 and the boss 123, facilitating the assembly of the display stand 10. Based on this, the ratio between the inner diameter of the second through-hole segment 1232 and the diameter of the second smooth rod segment 1422 can be between 0.2 and 0.4. If the aforementioned ratio is too small, the fastener 14 may be difficult to pass through the boss 123 due to the small gap between the smooth rod portion 142 and the third through hole section 1233, or the cost of the fastener 14 may be too high due to the large thickness of the second smooth rod section 1422. If the aforementioned ratio is too large, the boss 123 may have insufficient structural strength due to the small wall thickness at the third through hole section 1233, and the fastener 14 may have difficulty maintaining a high coaxiality with the boss 123 due to the large gap between the second smooth rod section 1422 and the third through hole section 1233, which is not conducive to the subsequent connection of the display frame 12 and the display frame 13. The ratio between the length of the first smooth rod section 1421 and the sum of the depths of the first through hole section 1231 and the third through hole section 1233 can be between 1 and 1.5. If the aforementioned ratio is too small, the reliability of the connection between display stand 12 and display stand 13 may be insufficient due to the short length of the threaded portion 143 extending into the display stand 13; if the aforementioned ratio is too large, the length of the second smooth rod section 1422 may be too short to fulfill its intended function. The depth of the first through hole section 1231 can be greater than or equal to the length of the threaded portion 143, allowing the threaded portion 143 to be fully accommodated within the first through hole section 1231, so that display stand 12 and display stand 13 are as close as possible before being fixed together by the fastener 14, thereby reducing the assembly difficulty of the display stand 10; the depth of the second through hole section 1232 can be greater than or equal to the length of the second smooth rod section 1422, allowing the fastener 14 to be screwed into place when connecting display stand 12 and display stand 13.

[0045] In some embodiments, the ratio between the height of the boss 123 and the height of the side plate 122 can be between 0.7 and 1. If the ratio is too small, the height difference between the boss 123 and the side plate 122 may be too small, causing the head 141 to sink too deeply into the display frame 12 after the fastener 14 passes through the boss 123 and before connecting the display frame 12 and the display frame 13. This makes it difficult for assembly personnel to fix the display frame 12 and the display frame 13 together by tightening the fastener 14 with their fingers. If the ratio is too large, the fastener 14 may protrude too much after connecting the display frame 12 and the display frame 13.

[0046] In some embodiments, the minimum distance between the boss 123 and the side plate 122 can be between 10mm and 12mm. If the aforementioned minimum distance is too small, it is easy for the distance between the boss 123 and the side plate 122 to be too small, making it difficult for assembly personnel to fix the display stand 12 and the display stand 13 together by tightening the fasteners 14 with their fingers; if the aforementioned minimum distance is too large, it is easy for the thickness of the display stand 13 to be too large, which is not conducive to reducing the cost of the display stand 10.

[0047] In some embodiments, the depth of the third through hole 1233 can be between 2 mm and 4 mm. If the depth is too small, the fastener 14 may not be able to be stopped by the third through hole 1233 after passing through the boss 123 and thus detach from the display frame 12; if the depth is too large, the tapping distance may be too large, making it difficult to assemble the fastener 14 and the display frame 12.

[0048] Based on the above description, this application provides a connection structure, which may include a first component to be connected, a second component to be connected, and a fastener 14. The first component to be connected may have a first through-hole section 1231 and a second through-hole section 1232, and a third through-hole section 1233 connecting the first through-hole section 1231 and the second through-hole section 1232. Among the first through-hole section 1231, the second through-hole section 1232, and the third through-hole section 1233, the third through-hole section 1233 has the smallest diameter. Correspondingly, the fastener 14 may include a head 141, a smooth rod portion 142 connected to the head 141, and a threaded portion 143 connected to the smooth rod portion 142. The diameter of the threaded portion 143 is greater than the inner diameter of the third through-hole section 1233 and smaller than the smaller of the diameters of the first through-hole section 1231 and the second through-hole section 1232. The fastener 14 is inserted into the second through hole section 1232, the third through hole section 1233 and the first through hole section 1231, and is threadedly connected to the aforementioned second part to be connected through the threaded portion 143. With this configuration, since the diameter of the threaded portion 143 is larger than the inner diameter of the third through-hole section 1233 and smaller than the smaller of the diameters of the first through-hole section 1231 and the second through-hole section 1232, the fastener 14 can only tap the thread of the third through-hole section 1233 during the process of passing through the aforementioned first part to be connected, that is, shorten the tapping distance, which helps to reduce the difficulty of assembling the fastener 14 with the aforementioned first part to be connected. Of course, the third through-hole section 1233 can also be pre-formed with threads, which also helps to shorten the distance of tightening the fastener 14, thereby helping to reduce the difficulty of assembling the fastener 14 with the aforementioned first part to be connected. Moreover, it makes it difficult for the fastener 14 to detach from the display frame 12 after passing through the aforementioned first part to be connected, which helps to reduce the risk of the fastener 14 falling or being lost. It also allows the threaded portion 143 to be at least partially accommodated in the first through-hole section 1231, so that the aforementioned first part to be connected and the aforementioned second part to be connected can be as close as possible before being fixed together by the fastener 14, which helps to reduce the difficulty of assembly.

[0049] Furthermore, the smooth rod portion 142 may include a first smooth rod segment 1421 and a second smooth rod segment 1422, with the first smooth rod segment 1421 being closer to the threaded portion 143 than the second smooth rod segment 1422. The diameter of the first smooth rod segment 1421 is smaller than the diameter of the second smooth rod segment 1422, and the diameter of the second smooth rod segment 1422 is larger than the inner diameter of the third through-hole segment 1233. This arrangement, since the second smooth rod segment 1422 is thicker than the first smooth rod segment 1421, helps to reduce the gap between the smooth rod portion 142 and the third through-hole segment 1233, thereby reducing the amplitude of the fastener 14's wobble within the aforementioned first component to be connected, and increasing the coaxiality between the fastener 14 and the aforementioned first component to be connected, facilitating subsequent assembly.

[0050] Based on the above description, this application provides a fastener 14 for connecting at least two components to be connected. Any one of the at least two components to be connected may have a first through hole segment 1231 and a second through hole segment 1232, as well as a third through hole segment 1233 connecting the first through hole segment 1231 and the second through hole segment 1232. Among the first through hole segment 1231, the second through hole segment 1232 and the third through hole segment 1233, the third through hole segment 1233 has the smallest diameter. Accordingly, the fastener 14 may include a head 141, a smooth rod portion 142 connected to the head 141, and a threaded portion 143 connected to the smooth rod portion 142. The smooth rod portion 142 may include a first smooth rod section 1421 and a second smooth rod section 1422. The first smooth rod section 1421 is closer to the threaded portion 143 than the second smooth rod section 1422. The diameter of the threaded portion 143 is larger than the inner diameter of the third through hole section 1233 and smaller than the smaller of the diameter of the first through hole section 1231 and the diameter of the second through hole section 1232. The fastener 14 passes through the second through hole section 1232, the third through hole section 1233, and the first through hole section 1231, and is threadedly connected to another component to be connected via the threaded portion 143. With this configuration, since the second smooth rod section 1422 is thicker than the first smooth rod section 1421, it is beneficial to reduce the gap between the smooth rod section 142 and the third through hole section 1233, thereby reducing the amplitude of the fastener 14 shaking in the part to be connected, and increasing the coaxiality between the fastener 14 and the part to be connected, so as to facilitate subsequent assembly.

[0051] As an example, combined Figures 1 to 6 The display stand 13 may include a base plate 131 and a side plate 132 connected to the base plate 131. A boss 123 may be provided in the area where the base plate 121 and the side plate 132 overlap. Fasteners 14 may allow the base plate 121 and the side plate 132 to abut against each other. In the area where the base plate 121 and the side plate 132 overlap, either the display stand 12 or the display stand 13 may have at least one protrusion, and the other may have grooves for accommodating the protrusion. The protrusion and the groove cooperate with each other to play the roles of foolproof, guiding and pre-fixing.

[0052] It should be noted that when the display stand 13 is made of plastic, it may include a threaded sleeve 133 made of metal, which may be embedded in the aforementioned plastic part. The fastener 14 connects the display stand 12 and the display stand 13 via a threaded portion 143 to the threaded sleeve 133, which helps to increase the reliability of the connection.

[0053] In some embodiments, the display stand 12 may include a partition 124 connected to the base plate 121. The partition 124 can divide the first accommodating space formed by the side plates 122 and the base plate 121 into a first sub-accommodating area 151 and a second sub-accommodating area 152, wherein the volume of the first sub-accommodating area 151 is smaller than the volume of the second sub-accommodating area 152. A boss 123 may be located in the first sub-accommodating area 151 and can be connected to the side plates 122 and the partition 124 respectively by reinforcing ribs 1234, thereby improving the structural strength of the display stand 12 at the boss 123 and increasing the reliability of the connection between the display stand 12 and the display stand 13. Further, the display stand 12 may include a cover plate 125, which can cover the open end of the second sub-accommodating area 152 to allow the second sub-accommodating area 152 to function as a relatively enclosed accommodating space.

[0054] In some embodiments, side panels 122 and bottom panels 121 can enclose a first accommodating space, and side panels 132 and bottom panels 131 can enclose a second accommodating space. Similarly, display rack 12 can include a cover plate 125, which can cover the open end of the first accommodating space away from the bottom panel 121 to allow display rack 12 to have a relatively enclosed accommodating space; display rack 13 can include a cover plate 134, which can cover the open end of the second accommodating space away from the bottom panel 131 to allow display rack 13 to have a relatively enclosed accommodating space. Therefore, the main control circuit board 111 can be disposed within display rack 13, and the first and second accommodating spaces can also respectively house other electronic components required for display stand 10. Furthermore, the number of bosses 123 can be multiple, for example... Figure 2 and Figure 4 The three areas shown can have multiple through-hole pairs 16 in the overlapping areas of the base plate 121 and the side plate 132, for example... Figure 2 and Figure 4The three are shown. Multiple through-hole pairs 16 and multiple bosses 123 can be alternately spaced, for example, at least one through-hole pair 16 between two adjacent bosses 123, making the spacing between adjacent bosses 123 relatively large, allowing the display stand 10 to be assembled with a smaller number of fasteners 14. Furthermore, each through-hole pair 16 can respectively connect the first accommodating space and the second accommodating space, so that electronic components connected to the main control circuit board 111 within the display stand 13 are exposed, and electronic components within the display stand 12 are connected to the main control circuit board 111. For example, the display stand 10 includes light strips and wires connected to the light strips disposed within the display frame 12, and a main control circuit board 111, a power socket 112, a power switch 113, and an adapter socket 114 disposed within the display frame 13. The light emitted by the aforementioned light strips can pass through the light-transmitting area of ​​the base plate 121. An adapter plug 126 can be provided at the end of the aforementioned wires away from the aforementioned light strips. The power socket 112 is connected to the main control circuit board 111 and is exposed through a through hole 16 to facilitate the placement of the power adapter for the display stand 10. The power switch 113 is connected to the main control circuit board 111 and is exposed through a through hole 16 to allow the user to turn the display stand 10 on / off. The adapter socket 114 is connected to the main control circuit board 111 and is exposed through another through hole 16 to allow the adapter plug 126 to be plugged into the adapter socket 114. The aforementioned light strips and at least part of the aforementioned wires are not visible because they are obscured by the cover plate 125.

[0055] It should be noted that the through-hole pair 16 mentioned in this application refers to the area where the base plate 121 and the side plate 132 overlap. The base plate 121 has a first through-hole, and the side plate 132 has a second through-hole. The first and second through-holes at least partially overlap after the display stand 12 and display stand 13 are assembled. The diameters of the first and second through-holes can be the same or different; the number of the first and second through-holes can be the same or different. For example: combined with... Figure 2 and Figure 4 There are two first through holes and three second through holes. After the display rack 12 and the display rack 13 are assembled, one of the first through holes overlaps with one of the first through holes to form a through hole pair 16, and the other of the first through holes overlaps with the remaining two of the second through holes to form two through hole pairs 16.

[0056] In some embodiments, the display stand 10 may include a main control circuit board 111 disposed within the display rack 13. The side of the base plate 131 opposite to the side plate 132 may be divided into a first display area 13a and a second display area 13b, the area of ​​the first display area 13a being smaller than the area of ​​the second display area 13b. The display stand 10 may include a display window 135 located in the first display area 13a and detachably connected to the base plate 131. The display window 135 is used to display an item 22 that cannot be experienced by the user, allowing the display window 135 and the item 22 to function as a replaceable module for easy replacement. The second display area 13b is used to display an item 21 that can be experienced by the user, and the item 21 can be connected to the main control circuit board 111 via a cable 30. The items 22 and 21 may be the same or similar, for example, both being headphones; or they may be different, for example, the items 21 and 22 may be headphones and the charging case for the headphones, respectively.

[0057] Furthermore, the side of the base plate 131 opposite to the side plate 132 can be divided into a third display area 13c and a fourth display area 13d, with the area of ​​the third display area 13c being smaller than that of the fourth display area 13d. The third display area 13c can be located on the side of the first display area 13a away from the display stand 12 and can be equipped with a nameplate that includes at least the product information of the displayed item 21. The fourth display area 13d can be located on the side of the second display area 13b away from the display stand 12 and can be equipped with a button assembly 40 for user operation of the display stand 10.

[0058] As an example, combined Figure 7 and Figure 1 The button assembly 40 may include multiple buttons 41 and connecting ribs 421 that connect the multiple buttons 41, for example... Figure 7 and Figure 1The four buttons 41 shown are connected by a connecting rib 421, allowing any button 41 to have a travel under external force. Each button 41 may include a cylindrical sidewall 411 connected to the connecting rib 421 and an end wall 412 integrally connected to one end of the cylindrical sidewall 411. The end wall 412 is provided with a cutout graphic 413, which may include at least one of a play / pause button, a next track button, a volume down button, and a volume up button. Accordingly, the connecting rib 421 may be located at the other end of the cylindrical sidewall 411 away from the end wall 412. Further, the button assembly 40 may include a light-transmitting element 43 installed inside the button 41 to allow light to pass through, so that the button assembly 40 can be "lit up". The light-transmitting element 43 may include a columnar body 431 and a graphic protrusion 432 connected to the columnar body 431. The columnar body 431 is located inside the cylindrical sidewall 411, and the graphic protrusion 432 is located inside the cutout graphic 413. With this configuration, since the light-transmitting element 43 is installed inside the button 41, that is, the two are processed separately and then assembled, the selection of materials for the button 41 and the light-transmitting element 43 is more flexible, and the related molding molds are simpler, which helps to reduce the manufacturing cost of the button assembly 40.

[0059] In some implementations, combined Figure 8 and Figure 9 All buttons 41 and connecting ribs 421 can be divided into single-key blocks equal in number to buttons 41, for example... Figure 8The four single-key blocks are shown in the dashed box. Each single-key block may include a button 41 and two connecting ribs 421. The end of the connecting rib 421 that is not connected to the button 41 may be provided with a support block 422. The support block 422 is used to contact the auxiliary circuit board 115, so that the connecting rib 421 is suspended relative to the auxiliary circuit board 115, thereby allowing any button 41 to have a stroke relative to the auxiliary circuit board 115 under the action of external force. With this arrangement, since both sides of each button 41 can be supported by the support blocks 422 respectively, it is not only beneficial to maintain the relative positional relationship between the button 41 and its light-transmitting element 43 and the auxiliary circuit board 115, but also beneficial to the smooth movement of the button 41 toward the auxiliary circuit board 115 when it is pressed. Furthermore, two adjacent single-key blocks can share a support block 422, which helps to simplify the structure of the button assembly 40. At this time, all the buttons 41, connecting ribs 421 and support blocks 422 can be integrally formed structural components. Viewed along the pressing direction of the button assembly 40, the geometric centers of all support blocks 422 and all buttons 41 can be collinear. This allows for uniform force distribution across all parts of any button 41 when pressed, and ensures that the button 41 smoothly returns to its original position after pressing. Furthermore, viewed along the pressing direction of the button assembly 40, each connecting rib 421 can be arc-shaped. This not only helps reduce the volume of the button assembly 40, allowing any button 41 to have a greater stroke under external force, but also reduces the risk of breakage between the connecting rib 421 and the button 41. The two connecting ribs 421 in each single button block can be rotationally symmetrical, with the center of symmetry being the geometric center of the corresponding button 41. This ensures uniform force distribution across all parts of any button 41 when pressed, and that the button 41 smoothly returns to its original position after pressing. Furthermore, the two support blocks 422 with the largest spacing can each be provided with mounting holes 423 to allow the button assembly 40 to be fixed at the mounting holes 423. For example, the connecting rib 421 is connected to the base plate 131 at the support block 422 by screws. In this context, combined with... Figures 7 to 9 In addition to the two support blocks 422 with the largest spacing having mounting holes 423 respectively, the other support blocks 422 can also have mounting holes 423, which helps to reduce the cost of the button assembly 40.

[0060] In some implementations, combined Figure 10 and Figure 11The light-transmitting element 43 may include a cylindrical outer wall 433 and a cylindrical inner core 434 connected to the end of the columnar body 431 away from the graphic protrusion 432. The cylindrical inner core 434 is located inside the cylindrical outer wall 433 and is used to trigger the corresponding switching device 116 under external force. The cylindrical outer wall 433 and the cylindrical inner core 434 may be further connected by reinforcing ribs 435, and multiple reinforcing ribs 435 may be arranged at intervals around the cylindrical inner core 434. Furthermore, the inner side of the cylindrical sidewall 411 may be provided with a protrusion extending along the axial direction of the button 41, and the cylindrical outer wall 433 may be provided with a groove 436 extending along the axial direction of the light-transmitting element 43. The aforementioned protrusion is located in the groove 436 to prevent misalignment during the assembly of the light-transmitting element 43 and the button 41, so that the graphic protrusion 432 can be located within the hollow graphic 413. The groove 436 can be located between two adjacent reinforcing ribs 435 in the circumferential direction of the light-transmitting element 43, and at least part of the cylindrical outer wall 433 is discontinuous in the circumferential direction of the light-transmitting element 43. Furthermore, all the grooves 436 and reinforcing ribs 435 can be evenly spaced in the circumferential direction of the light-transmitting element 43.

[0061] In some embodiments, the display stand 10 may include an auxiliary circuit board 115 disposed within the display rack 13, and the button assembly 40 may also be disposed within the display rack 13 and partially exposed to facilitate pressing by the user. The button assembly 40 is connected to the base plate 131 via connecting ribs 421, allowing multiple buttons 41 to be exposed through through holes in the base plate 131. The auxiliary circuit board 115 is located on the side of the button assembly 40 facing away from the base plate 131 and is connected to the base plate 131 to support the button assembly 40. Furthermore, the auxiliary circuit board 115 may be provided with multiple switching devices 116 and multiple LEDs 117, for example... Figure 7 The diagram shows four switching devices 116 and sixteen LED beads 117. Each switching device 116 corresponds one-to-one with a plurality of buttons 41, allowing each button 41 to trigger its corresponding switching device 116 through the light-transmitting element 43 under external force, thereby controlling the displayed object 21. Each button 41 corresponds to at least one LED bead 117, for example... Figure 7 The button 41 shown corresponds to four LED beads 117. The light emitted by the LED beads 117 is emitted through the corresponding light-transmitting element 43 to allow the button assembly 40 to be "lit up". Correspondingly, the display stand 10 may include a main control circuit board 111 connected to the base plate 131, an auxiliary circuit board 115 connected to the main control circuit board 111, and a control signal generated after the switching device 116 is triggered can be transmitted to the main control circuit board 111. It is worth noting that the auxiliary circuit board 115 and the main control circuit board 111 can be combined into a single circuit board. Figure 7 Of the four LEDs 117 surrounding each switching device 116, one is not visible because it is blocked by the switching device 116.

[0062] Based on the detailed description above, for display stands 12 and 13, the base plates 121 and 131 can be shaped as any one of triangles, rectangles, and semicircles, respectively, and the side plates 122 and 132 can have the same shape as the base plates 121 and 131, respectively. Therefore, the shapes of the base plates 121 and 131 can be combined according to actual needs. For example, both base plates 121 and 131 can be rectangular or semicircular, or one base plate 121 or 131 can be a quadrilateral and the other a semicircle. Furthermore, for the display device 100, the display stand 10 can include only one of display stands 12 and 13, and can still display at least one of the displayed items 21 and 22. For example, the display stand 10 only includes the display rack 13, which contains a main control circuit board 111 and its electronic components, an auxiliary circuit board 115 and its electronic components, and a button assembly 40. The displayed item 21 is connected to the main control circuit board 111 via a wire 30, and the displayed item 22 and its display window 135 are detachably connected to the display rack 13.

[0063] As an example, combined Figure 12 and Figure 1 The wire 30 may include a first conductive core 31 and a second conductive core 32 electrically insulated from each other. For example, at least one of the first conductive core 31 and the second conductive core 32 may be covered with an electrically insulating layer 33, and an elastic coating 34 may be covering the first conductive core 31 and the second conductive core 32. The elastic coating 34 has a better resilience than either the first conductive core 31 or the second conductive core 32, allowing the wire 30 to unwind under the rebound of the elastic coating 34 after being wound, thus reducing the probability of the wire 30 becoming tangled. Furthermore, combined with... Figure 13 A wire 30 of length L1 is wound twice with a diameter φ of 10cm and left to stand for 24 hours. The distance between the two ends of the unwound wire 30 is measured as L2. L2 / L1 ≥ 0.6 to allow the wire 30 to stretch to a greater extent to its initial state after being wound. Preferably, L2 / L1 ≥ 0.8.

[0064] In some embodiments, the material of the elastic coating 34 may include at least one of thermoplastic polyurethane elastomer (TPU), thermoplastic vulcanizate (TPV), and thermoplastic polyester elastomer (TPEE), which have good resilience.

[0065] In some embodiments, the ratio between the wall thickness of the elastic coating 34 and the bus diameter of the first conductive core wire 31 and the second conductive core wire 32 can be between 0.2 and 0.25. If the ratio is too small, the elastic coating 34 may make it difficult for the wire 30 to unwind after being wound; if the ratio is too large, the wire 30 may be difficult to wind. Furthermore, the first conductive core wire 31 can be configured as a multi-strand wire to make it more flexible, and the second conductive core wire 32 can also be configured as a multi-strand wire to make it more flexible. The second conductive core wire 32 can be twisted onto the first conductive core wire 31.

[0066] In some embodiments, the elastic coating 34 can be made transparent, and the second conductive core wire 32 can be made of multiple strands and twisted onto the first conductive core wire 31 to allow the metallic color of the second conductive core wire 32 to be visible, making the wire 30 appear like a security cable, which is simple, reliable, and low-cost. Among these, combined with... Figure 14 The cable 30 can be configured as a Y-shaped cable and used to connect two objects 21 to be displayed, such as headphones. In other words, the objects 21 to be displayed can be headphones, and there are two of them; the cable 30 can be configured as a Y-shaped cable to connect the two headphones. This configuration, because the cable 30 resembles an anti-theft cable, helps prevent the objects 21 from being stolen. Furthermore, the color of the second conductive core wire 32 can have a color difference from the color of the objects 21 to prevent the cable 30 from being mistaken for part of the objects 21.

[0067] In some embodiments, the main control circuit board 111 can transmit signals, such as audio signals, to the object being displayed 21 via the first conductive core wire 31 and the second conductive core wire 32, so that users can experience the object being displayed 21. The main control circuit board 111 may be provided with a socket terminal, and one end of the wire 30 may be provided with a plug terminal 35, which connects to the aforementioned socket terminal, allowing the object being displayed 21, the wire 30, and the plug terminal 35 to function as a replaceable module. This configuration, where the object being displayed 21 is configured as a replaceable module and connected to the main control circuit board 111, minimizes changes to the display stand 10 after the object being displayed 21 is replaced, thereby increasing the versatility of the display stand 10 and reducing its cost.

[0068] In some embodiments, the yellowing grade of the elastic coating 34 can be grade 0 or 1, preferably grade 0. The yellowing grade (ΔYI) represents the difference in yellowness index (YI) of the material before and after the yellowing test. The yellowness index (YI) can be used to characterize the degree of yellowing of colorless, transparent, translucent, or near-white polymer materials. The yellowing test can include at least one of thermo-oxidative aging and photo-oxidative aging. Obviously, the smaller the yellowing grade, the less the material yellows.

[0069] In some embodiments, the material of the elastic coating 34 may include a thermoplastic polyester elastomer, which not only has good resilience but is also transparent and does not easily yellow.

[0070] The following table shows the different types of yellowing tests conducted on the wire 30 when the material of the elastic coating 34 is thermoplastic polyester elastomer, in order to verify its reliability.
