[0049] The present application will be further described in detail below in conjunction with the accompanying drawings and examples. It is particularly noted that the following examples are only used to illustrate the present application and do not limit the scope of the present application. Similarly, the following examples are only some embodiments of the present application and not all embodiments. All other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application.

[0050] Reference to "embodiments" in this application means that a particular feature, structure, or characteristic described in conjunction with the embodiment may be included in at least one embodiment of this application. It is understood, both explicitly and implicitly, by those skilled in the art that the embodiments described in this application may be combined with other embodiments.

[0051] By way of example, in conjunction with Figures 1 to 3 , a display device 100 may include a display stand 10, an exhibit 21 displayed on the display stand 10, and a cable 30 connecting the exhibit 21 and the display stand 10. The exhibit 21 can be experienced by a user, for example, by the user wearing the exhibit 21. Furthermore, a main control circuit board 111 may be provided within the display stand 10, and the exhibit 21 may be connected to the main control circuit board 111 via the cable 30, allowing the display stand 10 to transmit signals to the exhibit 21 via the cable 30, thereby facilitating the user's experience of the exhibit 21. In this regard, the exhibit 21 may be an electronic device with audio playback capabilities, such as headphones or smart glasses. With this arrangement, when a user is experiencing the exhibit 21, they can control the exhibit 21 to play audio files pre-stored in the display device 100 using the button assembly 40, such as the play / pause button, next song button, volume down button, and volume up button, on the display stand 10. This eliminates the need for the user to connect a personal terminal device, such as a mobile phone. This is simple and convenient, and helps improve the user's experience with the exhibit 21. It is worth noting that if the exhibit 21 is headphones, the charging case sold with the headphones can also be displayed.

[0052] By way of example, in conjunction with Figures 1 to 6 , a display stand 10 may include a display stand 12, a display stand 13, and a fastener 14. Fastener 14 can detachably fasten display stands 12 and 13 together. Display stand 12 may include a base plate 121, a side plate 122 connected to base plate 121, and a boss 123. Boss 123 and side plate 122 are located on the same side of base plate 121. Boss 123 may further define a first through-hole section 1231, a second through-hole section 1232, and a third through-hole section 1233 connecting first through-hole section 1231 and second through-hole section 1232. Second through-hole section 1232 may be further away from base plate 121 than first through-hole section 1231. Of the first through-hole section 1231, second through-hole section 1232, and third through-hole section 1233, third through-hole section 1233 has the smallest aperture. Accordingly, fastener 14 may include a head 141, a smooth shaft 142 connected to head 141, and a threaded portion 143 connected to smooth shaft 142. The diameter of threaded portion 143 is larger than the inner diameter of third through-hole section 1233 and smaller than the smaller of the diameters of first through-hole section 1231 and second through-hole section 1232. Fastener 14 is disposed within second through-hole section 1232, third through-hole section 1233, and first through-hole section 1231, and is threadedly connected to display stand 13 via threaded portion 143.With this arrangement, since the boss 123 is provided with the first through hole section 1231 and the second through hole section 1232, and the 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 in height relative to the base plate 121, which helps to shorten the height difference between the boss 123 and the side plate 122. As a result, the head 141 does not sink too deeply into the display rack 12 after the fastener 14 is inserted into the boss 123 and before the display rack 12 and the display rack 13 are connected. This helps to reduce the risk of the assembler's fingers being interfered with by the side plate 122, allowing the assembler to fix the display rack 12 and the display rack 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 hole diameter of the first through hole section 1231 and the hole diameter of the third through hole section 1233, the threaded portion 141 can be higher in height relative to the base plate 121, which 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 only self-tap the threads of the third through-hole section 1233 during the process of being inserted into the boss 123, thereby shortening the tapping distance and facilitating reduced difficulty in assembling the fastener 14 and the display stand 12, but of course the third through-hole section 1233 may also be pre-formed with threads, which also facilitates shortening the distance for screwing the fastener 14, thereby facilitating reduced difficulty in assembling the fastener 14 and the display stand 12, and further, makes it difficult for the fastener 14 to separate from the display stand 12 after being inserted into the boss 123, thereby reducing the risk of the fastener 14 falling or being lost, and further allows the threaded portion 143 to be at least partially accommodated within the first through-hole section 1231, thereby allowing the display stands 12 and 13 to be as close as possible before being fixed together by the fastener 14, thereby facilitating reduced difficulty in assembling the display stand 10.

[0053] In some embodiments, the ratio of the depth of the third through-hole section 1233 to the length of the threaded portion 143 can be between 0.6 and 1. If the ratio is too small, the fastener 14 may not be stopped by the third through-hole section 1233 after passing through the boss 123, and may be removed from the display stand 12. If the ratio is too large, the tapping distance may be too long, making it difficult to assemble the fastener 14 and the display stand 12.

[0054] In some embodiments, the polished rod portion 142 may include a first polished rod segment 1421 and a second polished rod segment 1422. The first polished rod segment 1421 is closer to the threaded portion 143 than the second polished rod segment 1422. The diameter of the first polished rod segment 1421 is smaller than that of the second polished rod segment 1422, which in turn has a larger diameter than the inner diameter of the third through-hole segment 1233. This arrangement, because the second polished rod segment 1422 is thicker than the first polished rod segment 1421, helps reduce the gap between the polished rod portion 142 and the third through-hole segment 1233, thereby reducing the amount of wiggle between the fastener 14 within the boss 123 and increasing the coaxiality between the fastener 14 and the boss 123, facilitating assembly of the display stand 10. For this reason, the ratio between the inner diameter of the second through-hole segment 1232 and the diameter of the second polished rod segment 1422 can be between 0.2 and 0.4. If the ratio is too small, the fastener 14 may be difficult to insert into the boss 123 due to the small gap between the polished rod portion 142 and the third through-hole segment 1233, or the fastener 14 may be too thick due to the thickness of the second polished rod segment 1422, resulting in excessive cost. If the ratio is too large, the boss 123 may be too thin at the third through-hole segment 1233, resulting in insufficient structural strength, or the fastener 14 may be difficult to maintain high coaxiality with the boss 123 due to the large gap between the second polished rod segment 1422 and the third through-hole segment 1233, hindering the subsequent connection between the display racks 12 and 13. The ratio of the length of the first polished rod segment 1421 to the sum of the depths of the first through-hole segment 1231 and the depths of the third through-hole segment 1233 may be between 1 and 1.5. If the aforementioned ratio is too small, the connection between display racks 12 and 13 may be less reliable due to the short length of threaded portion 143 extending into display rack 13. If the aforementioned ratio is too large, the length of second polished rod segment 1422 may be too short, making it difficult to achieve the intended function. The depth of first through-hole segment 1231 can be greater than or equal to the length of threaded portion 143 to allow threaded portion 143 to be fully accommodated within first through-hole segment 1231, allowing display racks 12 and 13 to be as close together as possible before being secured together by fasteners 14, thereby reducing the difficulty of assembling display stand 10. The depth of second through-hole segment 1232 can be greater than or equal to the length of second polished rod segment 1422 to allow fasteners 14 to be screwed into place when connecting display racks 12 and 13.

[0055] In some embodiments, the ratio of the height of boss 123 to the height of side panel 122 can be between 0.7 and 1. If the ratio is too small, the height difference between boss 123 and side panel 122 may be too small, causing head 141 to sink too deeply into display frame 12 after fastener 14 is inserted through boss 123 and before display frames 12 and 13 are connected, making it difficult for assemblers to tighten fastener 14 with their fingers to secure display frames 12 and 13 together. If the ratio is too large, fastener 14 may protrude too much after display frames 12 and 13 are connected.

[0056] In some embodiments, the minimum distance between the boss 123 and the side panel 122 can be between 10 mm and 12 mm. If the minimum distance is too small, the distance between the boss 123 and the side panel 122 may be too small, making it difficult for assemblers to tighten the fasteners 14 with their fingers to secure the display racks 12 and 13 together. If the minimum distance is too large, the thickness of the display rack 13 may be too large, hindering the cost of the display stand 10.

[0057] In some embodiments, the depth of the third through-hole section 1233 can be between 2 mm and 4 mm. If the depth is too small, the fastener 14 may not be stopped by the third through-hole section 1233 after being inserted into the boss 123, and may be removed from the display stand 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 stand 12.

[0058] Based on the above description, the present application provides a connection structure, which may include a first member to be connected, a second member to be connected, and a fastener 14. The first member to be connected may be provided with 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 third through-hole section 1233 has the smallest aperture among the first through-hole section 1231, the second through-hole section 1232, and the third through-hole section 1233. 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 aperture of the first through-hole section 1231 and the aperture of the second through-hole section 1232. The fastener 14 is passed 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 aforementioned second to-be-connected member through the threaded portion 143 . 1232 , the threaded portion 143 is at least partially accommodated within the first through-hole section 1231 , thereby allowing the first and second through-hole sections 1231 to be brought as close together as possible before being secured together by the fastener 14 .

[0059] Furthermore, the polished rod portion 142 may include a first polished rod segment 1421 and a second polished rod segment 1422. The first polished rod segment 1421 is closer to the threaded portion 143 than the second polished rod segment 1422. The diameter of the first polished rod segment 1421 is smaller than that of the second polished rod segment 1422, which in turn has a larger diameter than the inner diameter of the third through-hole segment 1233. This arrangement, because the second polished rod segment 1422 is thicker than the first polished rod segment 1421, helps narrow the gap between the polished rod portion 142 and the third through-hole segment 1233, thereby reducing the amount of movement of the fastener 14 within the first component to be connected and increasing the coaxiality between the fastener 14 and the first component to be connected, facilitating subsequent assembly.

[0060] Based on the above-mentioned relevant description, the present application provides a fastener 14, which is used to connect at least two parts to be connected. Any one of the at least two parts to be connected can be provided with 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. The aperture of the third through hole section 1233 is the smallest among the first through hole section 1231, the second through hole section 1232 and the third through hole section 1233. Accordingly, the fastener 14 may include a head 141, a polished rod portion 142 connected to the head 141, and a threaded portion 143 connected to the polished rod portion 142. The polished rod portion 142 may include a first polished rod segment 1421 and a second polished rod segment 1422. The first polished rod segment 1421 is closer to the threaded portion 143 than the second polished rod segment 1422. The diameter of the threaded portion 143 is larger than the inner diameter of the third through-hole segment 1233 and smaller than the smaller of the aperture of the first through-hole segment 1231 and the aperture of the second through-hole segment 1232. The fastener 14 is disposed within the second through-hole segment 1232, the third through-hole segment 1233, and the first through-hole segment 1231, and is threadedly connected to another component to be connected via the threaded portion 143. With this arrangement, since the second polished rod segment 1422 is thicker than the first polished rod segment 1421, it is beneficial to narrow the gap between the polished rod portion 142 and the third through hole segment 1233, thereby reducing the swing amplitude of the fastener 14 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.

[0061] By way of example, referring to Figures 1 to 6 , display stand 13 may include a bottom plate 131 and side plates 132 connected to bottom plate 131. Bosses 123 may be provided in the overlapping region of bottom plate 121 and side plates 132, and fasteners 14 may enable bottom plate 121 to abut against side plates 132. In the overlapping region of bottom plate 121 and side plates 132, either display stand 12 or display stand 13 may be provided with at least one boss, and the other may be provided with a groove for accommodating each boss. The bosses and grooves cooperate to provide anti-fouling, guiding, and pre-fixing functions.

[0062] It should be noted that when the display frame 13 is made of plastic, the display frame 13 may include a metal threaded sleeve 133, which may be embedded in the plastic. The fastener 14, when connecting the display frames 12 and 13, is threadedly connected to the threaded sleeve 133 via the threaded portion 143, thereby increasing the reliability of the connection.

[0063] In some embodiments, the display rack 12 may include a partition 124 connected to the bottom panel 121. The partition 124 can divide the first accommodation space formed by the side panels 122 and the bottom panel 121 into a first sub-accommodation area 151 and a second sub-accommodation area 152. The volume of the first sub-accommodation area 151 is smaller than that of the second sub-accommodation area 152. The boss 123 can be located in the first sub-accommodation area 151 and can be connected to the side panels 122 and the partition 124 respectively via reinforcing ribs 1234. This improves the structural strength of the display rack 12 at the boss 123 and facilitates increased reliability of the connection between the display racks 12 and 13. Furthermore, the display rack 12 can include a cover 125 that can cover the open end of the second sub-accommodation area 152, allowing the second sub-accommodation area 152 to function as a relatively enclosed accommodation space.

[0064] In some embodiments, the side panels 122 and bottom panel 121 can enclose a first storage space, and the side panels 132 and bottom panel 131 can enclose a second storage space. Similarly, the display stand 12 can include a cover 125 that can be positioned over the open end of the first storage space away from the bottom panel 121, allowing the display stand 12 to have a relatively enclosed storage space. The display stand 13 can also include a cover 134 that can be positioned over the open end of the second storage space away from the bottom panel 131, allowing the display stand 13 to have a relatively enclosed storage space. Therefore, the main control circuit board 111 can be positioned within the display stand 13, and the first and second storage spaces can also be respectively equipped with other electronic components required for the display stand 10. Furthermore, the number of bosses 123 can be multiple, such as the three shown in Figures 2 and 4. The overlapping area between the bottom panel 121 and the side panels 132 can be provided with multiple pairs of through holes 16, such as the three shown in Figures 2 and 4. The multiple pairs of through holes 16 and the multiple bosses 123 can be arranged alternately and spaced apart. For example, at least one pair of through holes 16 can be positioned between two adjacent bosses 123. This allows for a relatively large spacing between adjacent bosses 123, allowing the display stand 10 to be assembled using a smaller number of fasteners 14. Furthermore, each pair of through holes 16 can connect the first accommodating space with the second accommodating space, facilitating the exposure of electronic components connected to the main control circuit board 111 within the display stand 13, and the connection of electronic components within the display stand 12 to the main control circuit board 111. For example, display stand 10 includes a light bar and wires connected to the light bar, disposed within display frame 12, as well as a main control circuit board 111, a power socket 112, a power switch 113, and an adapter socket 114, disposed within display frame 13. Light emitted by the light bar can pass through a light-transmitting area of ​​bottom plate 121. An adapter plug 126 may be provided at the end of the wires away from the light bar. Power socket 112 is connected to main control circuit board 111 and exposed through a pair of through holes 16 to facilitate installation of a power adapter for display stand 10. Power switch 113 is connected to main control circuit board 111 and exposed through one pair of through holes 16 to allow a user to turn display stand 10 on and off. Adapter socket 114 is connected to main control circuit board 111 and exposed through another pair of through holes 16 to allow adapter plug 126 to connect to adapter socket 114. The light bar and at least some of the wires are obscured from view by a cover 125.

[0065] It should be noted that the through-hole pair 16 described in the present application may refer to the area where the bottom plate 121 and the side plate 132 overlap, wherein a first through-hole is provided on the bottom plate 121 and a second through-hole is provided on the side plate 132. The first through-hole and the second through-hole are at least partially overlapped after the display rack 12 and the display rack 13 are assembled. The apertures of the first through-hole and the second through-hole may be the same or different; and the number of the first through-hole and the second through-hole may be the same or different. For example, in conjunction with Figures 2 and 4 , the number of the first through-holes is two, and the number of the second through-holes is three. After the display rack 12 and the display rack 13 are assembled, one of the first through-holes is overlapped with one of the second through-holes to form one through-hole pair 16, and another of the first through-holes is overlapped with the remaining two of the second through-holes to form two through-hole pairs 16.

[0066] In some embodiments, the display stand 10 may include a main control circuit board 111 disposed within a display frame 13. The side of the bottom plate 131 facing away from 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 may be smaller than that 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 bottom plate 131. The display window 135 is used to display an item 22 that is not user-experienced, 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 is user-experienced. The item 21 may be connected to the main control circuit board 111 via a cable 30. The items 22 and 21 may be identical or similar, for example, both being headphones. Alternatively, the items 22 and 21 may be different, for example, the headphones and their charging case, respectively.

[0067] Furthermore, the side of the bottom plate 131 facing away from the side plate 132 can be divided into a third display area 13c and a fourth display area 13d. The area of ​​the third display area 13c can be 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 rack 12 and can be provided with a nameplate containing at least 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 rack 12 and can be provided with a button assembly 40 for user operation of the display stand 10.

[0068] As an example, in conjunction with Figure 7 and Figure 1, the key assembly 40 may include a plurality of keys 41 and a connecting rib 421 connecting the plurality of keys 41, such as the four keys 41 shown in Figure 7 and Figure 1. The connecting rib 421 allows any key 41 to have a travel under the action of an external force. Each key 41 may include a cylindrical side wall 411 connected to the connecting rib 421 and an end wall 412 integrally connected to one end of the cylindrical side wall 411. The end wall 412 is provided with a hollow graphic 413. The hollow graphic 413 may include at least one of a play / pause key, a next song key, a volume down key, and a volume up key. Accordingly, the connecting rib 421 may be located at the other end of the cylindrical side wall 411 away from the end wall 412. Furthermore, the key assembly 40 may include a light-transmitting member 43 installed in the key 41 to allow light to pass through, so as to allow the key assembly 40 to be "lit up". The light-transmitting member 43 may include a columnar body 431 and a graphic protrusion 432 connected to the columnar body 431. The columnar body 431 is located within the cylindrical sidewall 411, and the graphic protrusion 432 is located within the hollow graphic 413. This arrangement allows the light-transmitting member 43 to be installed within the key 41, that is, the two are processed separately and then assembled. This allows for greater flexibility in the selection of materials for the key 41 and the light-transmitting member 43, simplifies the associated molding molds, and helps reduce the manufacturing cost of the key assembly 40.

[0069] In some embodiments, referring to Figures 8 and 9 , all keys 41 and connecting ribs 421 can be divided into single-key blocks equal to the number of keys 41, such as the four single-key blocks shown in the dashed box in Figure 8 . Each single-key block can include one key 41 and two connecting ribs 421. The end of the connecting rib 421 not connected to the key 41 can be provided with a support block 422. The support block 422 is configured to contact the auxiliary circuit board 115 so that the connecting rib 421 is suspended relative to the auxiliary circuit board 115, thereby allowing each key 41 to have a travel relative to the auxiliary circuit board 115 under the action of an external force. This arrangement, since both sides of each key 41 can be supported by the support blocks 422, not only helps maintain the relative positional relationship between the key 41 and the light-transmitting member 43 therein and the auxiliary circuit board 115, but also helps ensure that the key 41 moves smoothly toward the auxiliary circuit board 115 when pressed. Furthermore, two adjacent single-key blocks can share a support block 422, which helps simplify the structure of the key assembly 40. At this time, all the buttons 41, connecting ribs 421 and support blocks 422 can be integrally formed structural components. When viewed along the pressing direction of the button assembly 40, the geometric centers of all the support blocks 422 and the geometric centers of all the buttons 41 can be arranged to be collinear, so that when any button 41 is pressed, the external force is evenly applied to all parts of the support blocks 422, and the button 41 smoothly returns to its original position after the pressing is completed. Furthermore, when viewed along the pressing direction of the button assembly 40, each connecting rib 421 can be arranged to be arc-shaped, which not only helps to reduce the volume of the button assembly 40 to allow any button 41 to have a larger stroke under the action of external force, but also reduces the risk of the connecting rib 421 and the button 41 breaking. The two connecting ribs 421 in each single-key block can be arranged to be rotationally symmetrical, with the center of symmetry being the geometric center of the corresponding button 41, so that when any button 41 is pressed, the external force is evenly applied to all parts of the support blocks 422, and the button 41 smoothly returns to its original position after the pressing is completed. Furthermore, the two support blocks 422 with the largest spacing between them can each be provided with a mounting hole 423 to allow the key assembly 40 to be fixed at the mounting hole 423. For example, the connecting rib 421 can be connected to the base plate 131 at the support block 422 via screws. Referring to Figures 7 to 9, in addition to the two support blocks 422 with the largest spacing between them being provided with mounting holes 423, the other support blocks 422 can also be provided with mounting holes 423, which helps reduce the cost of the key assembly 40.

[0070] In some embodiments, referring to Figures 10 and 11 , the light-transmitting member 43 may include a cylindrical outer wall 433 connected to the end of the columnar body 431 away from the graphic protrusion 432, and a cylindrical inner core 434. The cylindrical inner core 434 is located inside the cylindrical outer wall 433 and is used to trigger the corresponding switch device 116 under the action of an external force. The cylindrical outer wall 433 and the cylindrical inner core 434 may be further connected by a reinforcing rib 435. A plurality of reinforcing ribs 435 may be spaced around the cylindrical inner core 434. Furthermore, the inner side of the cylindrical sidewall 411 may be provided with a ridge extending axially along the key 41, and the cylindrical outer wall 433 may be provided with a groove 436 extending axially along the light-transmitting member 43. The ridge is located within the groove 436 to prevent misalignment during assembly of the light-transmitting member 43 and the key 41, thereby ensuring that the graphic protrusion 432 can be located within the hollowed-out graphic 413. The slots 436 may be located between two adjacent reinforcing ribs 435 in the circumferential direction of the light-transmitting member 43, and make at least a portion of the cylindrical outer wall 433 discontinuous along the circumferential direction of the light-transmitting member 43. Furthermore, all the slots 436 and reinforcing ribs 435 may be evenly spaced and distributed in the circumferential direction of the light-transmitting member 43.

[0071] In some embodiments, the display stand 10 may include an auxiliary circuit board 115 disposed within the display frame 13. The button assembly 40 may also be disposed within the display frame 13 and partially exposed to facilitate user depressibility. The button assembly 40 may be connected to the base plate 131 via connecting ribs 421, with the multiple buttons 41 exposed 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 switch devices 116 and multiple lamp beads 117, such as the four switch devices 116 and sixteen lamp beads 117 shown in FIG7 . The multiple switch devices 116 are provided in a one-to-one correspondence with the multiple buttons 41, allowing the buttons 41 to trigger the corresponding switch devices 116 through the light-transmitting member 43 under the action of an external force, thereby controlling the displayed object 21. Each button 41 is provided with at least one lamp bead 117, such as the one button 41 shown in FIG7 corresponding to four lamp beads 117. Light emitted by the lamp bead 117 is emitted through the corresponding light-transmitting member 43, allowing the button assembly 40 to be "illuminated." Accordingly, the display stand 10 may include a main control circuit board 111 connected to the base plate 131. The auxiliary circuit board 115 may be connected to the main circuit board 111, and the control signals generated by the switch devices 116 when triggered may be transmitted to the main circuit board 111. It is worth noting that the auxiliary circuit board 115 and the main control circuit board 111 can be combined into one circuit board, and one of the four lamp beads 117 around each switch device 116 in FIG. 7 is not visible because it is blocked by the switch device 116 .

[0072] Based on the detailed description above, for display racks 12 and 13, the shapes of bottom plates 121 and 131 can be configured as any of a triangle, a rectangle, and a semicircle, respectively. The shapes of side plates 122 and 132 can be consistent with the shapes of bottom plates 121 and 131, respectively. Based on this, the shapes of bottom plates 121 and 131 can be combined according to actual needs. For example, the shapes of bottom plates 121 and 131 can both be configured as rectangles or semicircles, or one of bottom plates 121 and 131 can be a quadrilateral and the other a semicircle. Furthermore, for display device 100, display stand 10 can include only one of display racks 12 and 13, and can also display at least one of display objects 21 and 22. For example, the display stand 10 includes only a display frame 13 , which contains a main control circuit board 111 and electronic components thereon, an auxiliary circuit board 115 and electronic components thereon, and a button assembly 40 . The exhibit 21 is connected to the main control circuit board 111 via a wire 30 , and the exhibit 22 and its display window 135 are detachably connected to the display frame 13 .

[0073] As an example, in conjunction with Figure 12 and Figure 1, the wire 30 may include a first conductive core 31 and a second conductive core 32 that are electrically insulated from each other, for example, at least one of the first conductive core 31 and the second conductive core 32 is coated with an electrically insulating layer 33, and an elastic coating 34 that covers the first conductive core 31 and the second conductive core 32. The elastic coating 34 has a resilience that is superior to the resilience of either the first conductive core 31 or the second conductive core 32, allowing the wire 30 to stretch under the rebound action of the elastic coating 34 after being wound, thereby reducing the probability of the wire 30 becoming tangled. Furthermore, in conjunction with Figure 13, a wire 30 of length L1 is wound twice with a diameter of φ of 10 cm and then left to rest for 24 hours, and the distance between the two end points of the stretched wire 30 is measured as L2. L2 / L1 ≥ 0.6 allows the wire 30 to stretch to a large extent to its initial state after being wound. Preferably, L2 / L1≥0.8.

[0074] In some embodiments, the material of the elastic covering 34 may include at least one of thermoplastic polyurethane (TPU), thermoplastic vulcanizate (TPV), and thermoplastic polyester elastomer (TPEE), which have good resilience.

[0075] In some embodiments, the ratio between the wall thickness of the elastic coating 34 and the total diameter of the first conductive core 31 and the second conductive core 32 can be between 0.2 and 0.25. If the ratio is too small, the elastic coating 34 may have difficulty in allowing the wire 30 to stretch after being wound; if the ratio is too large, the wire 30 may be difficult to wind. Furthermore, the first conductive core 31 can be configured as a multi-stranded wire to make it more flexible, and the second conductive core 32 can be configured as a multi-stranded wire to make it more flexible. The second conductive core 32 can be twisted onto the first conductive core 31.

[0076] In some embodiments, the elastic coating 34 can be configured as a transparent structure, and the second conductive core wire 32 can be configured as a multi-strand wire and twisted on the first conductive core wire 31 to allow the metallic color of the second conductive core wire 32 to be revealed, so that the wire 30 looks like an anti-theft wire, which is simple, reliable, and low-cost. In particular, in conjunction with Figure 14, the wire 30 can be configured as a Y-shaped wire and used to connect two exhibits 21, and the exhibits 21 can be headphones. In other words, the exhibits 21 can be headphones, and there are two of them, and the wire 30 can be configured as a Y-shaped wire to connect the two headphones. In this way, since the wire 30 looks like an anti-theft wire, it is helpful to prevent the exhibits 21 from being taken away. Furthermore, there can be a color difference between the color of the second conductive core wire 32 and the color of the exhibit 21, which is helpful to prevent the wire 30 from being mistaken for a part of the exhibit 21.

[0077] In some embodiments, the main control circuit board 111 can transmit signals, such as audio signals, to the exhibited object 21 via the first conductive wire 31 and the second conductive wire 32, thereby facilitating a user experience of the exhibited object 21. The main control circuit board 111 can be provided with a socket terminal, and one end of the wire 30 can be provided with a plug terminal 35. The plug terminal 35 plugs into the socket terminal, allowing the exhibited object 21, the wire 30, and the plug terminal 35 to function as a replaceable module. This configuration allows the exhibited object 21, the wire 30, and the plug terminal 35 to function as a replaceable module. Because the exhibited object 21 is configured as a replaceable module and plugs into the main control circuit board 111, the display stand 10 can be minimally modified after the exhibited object 21 is replaced, thereby increasing the versatility of the display stand 10 and reducing its cost.

[0078] In some embodiments, the yellowing degree of the elastic coating 34 can be 0 or 1, preferably 0. The yellowing degree (ΔYI) can represent the difference in the yellowness index (YI) of a material before and after a 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 thermal oxidative aging and photooxidative aging. Obviously, the smaller the yellowing degree, the less yellowing the material will undergo.

[0079] In some embodiments, the material of the elastic covering layer 34 may include thermoplastic polyester elastomer, which not only has good resilience but is also transparent and does not easily turn yellow.

[0080] When the material of the elastic coating 34 is a thermoplastic polyester elastomer, different types of yellowing tests are performed on the wire 30 to verify its reliability, as shown in the following table.

[0081] The above descriptions are only some embodiments of the present application and do not limit the scope of protection of the present application. Any equivalent device or equivalent process transformation made using the contents of the description and drawings of this application, or directly or indirectly applied in other related technical fields, are also included in the scope of patent protection of this application.
