[0042] During the sales process, to allow consumers to better select and try out the headphones, merchants display them on a platform using a support frame. In related technologies, the headphone support frame is typically fixed to the display platform, requiring fixing and wiring operations inside the platform, which increases assembly complexity.

[0043] This application proposes a display rack, such as Figures 1 to 4 As shown, in some embodiments, the display rack 1000 includes a display platform 100, a mounting platform 200, and a support frame 300. The display platform 100 has a mounting cavity 110 and a through hole 120 located at the top. The mounting cavity 110 refers to the hollow structure inside the display platform 100 used to accommodate the mounting platform 200. Specifically, it can be formed by injection molding or welding of metal sheets. The depth of the mounting cavity 110 can be adjusted according to the dimensions of the internal structure. The through hole 120 serves as a connection channel between the mounting platform 200 and the support frame 300. Its diameter must ensure that the projection of the first conductive structure 210 falls completely into the hole to avoid misalignment during external assembly.

[0044] After the mounting platform 200 is installed inside the display platform 100, the first conductive structure 210 can be located inside the mounting cavity 110 or extend from the through hole 120. The support frame 300 can move circumferentially along the through hole 120, realizing the direct assembly of the support frame 300 from the outside of the display platform 100, and the second conductive structure 310 forms contact conductivity with the first conductive structure 210.

[0045] This embodiment utilizes a built-in mounting platform 200 and an externally detachable support frame 300 to decompose the assembly process into two independent stages: internal installation on the mounting platform 200 and external assembly on the support frame 300. The operating space is extended to both the interior of the mounting cavity 110 and the open area at the top of the display platform 100. The support frame 300, as an independent module, can be quickly installed externally, eliminating the impact of the confined internal space on operation and reducing assembly difficulty.

[0046] The support frame 300 in this application can rotate to display the exhibit 2000 at different angles, or it can be fixed at the required angle after installation. This application does not limit this.

[0047] The following explanation uses the example of a rotating support frame 300 and an earphone as exhibit 2000.

[0048] like Figures 1 to 4 As shown, in some embodiments, the display rack 1000 includes a display platform 100, a mounting platform 200, a drive component 500, and a support frame 300. The display platform 100 has a mounting cavity 110 and a top through hole 120; the mounting cavity 110 refers to the cavity structure inside the display platform 100 used to accommodate the mounting platform 200 and the drive component 500, and can be formed by injection molding or welding of metal sheets. The depth of the mounting cavity 110 can be adjusted according to the size of the drive component 500. The through hole 120 serves as a connection channel between the mounting platform 200 and the support base. Its diameter must ensure that the projection of the top first conductive structure 210 installed at the top of the platform falls completely into the hole to avoid misalignment during external assembly. The mounting platform 200 is equipped with a first conductive structure 210 and connected to an external power source via an electric slip ring 600. The electric slip ring 600 is a device that enables power transmission between rotating and stationary components. It can be a copper alloy ring with a carbon brush contact structure to ensure continuous power supply when the mounting platform 200 rotates. The electric slip ring 600 typically includes an inner ring and an outer ring. The inner ring contacts the component that needs to rotate, and the outer ring is usually fixed. In this embodiment, the inner ring can be sleeved on the output shaft 510 of the drive component 500, the mounting platform 200, or the connection between the output shaft 510 and the mounting platform 200, and is electrically connected to the first conductive structure 210. The outer ring is electrically connected to an external power source. The support frame 300 is equipped with a second conductive structure 310, which is detachably connected to the mounting platform 200. The second conductive structure 310 contacts the first conductive structure 210 to form a conductive circuit, which is used to place the exhibit 2000 and charge the exhibit 2000. When the drive component 500 drives the mounting platform 200 to rotate, it drives the support frame 300 and the exhibit 2000 to rotate synchronously.

[0049] After the drive unit 500 is installed inside the display platform 100, the mounting platform 200 extends to the through hole 120 area via the output shaft 510. The first conductive structure 210 on the top of the mounting platform 200 is connected to an external power source via an electric slip ring 600. When the support frame 300 is directly assembled from outside the display platform 100, the second conductive structure 310 and the first conductive structure 210 form contact and conduction. After the drive unit 500 is started, it drives the mounting platform 200 to rotate, and the support frame 300 rotates synchronously. The structure of the electric slip ring 600 ensures that the connection between the mounting platform 200 and the external power source is not affected by cable entanglement when the mounting platform 200 rotates, while the projection constraint design of the first conductive structure 210 ensures that the contacts are automatically aligned during external assembly. When the support frame 300 is disassembled for maintenance, it is only necessary to disconnect it from the mounting platform 200, without having to enter the mounting cavity 110 for operation.

[0050] This embodiment utilizes a built-in drive unit 500, a mounting platform 200, and an external detachable support frame 300 to decompose the assembly process into two independent stages: the internal installation of the drive unit 500 and the mounting platform 200, and the external assembly of the support frame 300. This expands the operating space to both the interior of the mounting cavity 110 and the open area at the top of the display platform 100. The support frame 300, as an independent module, can be quickly installed externally, eliminating the impact of the confined internal space on operation.

[0051] The first conductive structure 210 and the second conductive structure 310 can adopt common conductive structures, such as a combination of spring pin and copper pad, a combination of USB male and female connector, a combination of Type-C male and female connector, etc. This application does not limit them.

[0052] The detachable connection between the support frame 300 and the mounting platform 200 includes snap-fit, magnetic or threaded fastening, for example, a dovetail groove is provided on the top of the support platform and a corresponding slider is provided on the bottom of the support frame 300 to enable quick insertion and removal.

[0053] In some embodiments, please refer to Figure 5The output shaft 510 of the drive unit 500 is provided with a first half-shaft 511. The first half-shaft 511 refers to the segmented shaft section at the end of the output shaft 510 of the drive unit 500. Specifically, it can be implemented by a longitudinally cut cylindrical structure. The end face of the first half-shaft 511 is provided with a positioning boss or groove. The bottom of the mounting platform 200 is provided with a second half-shaft 220. The first conductive structure 210 and the second half-shaft 220 are located on opposite sides of the mounting platform 200. The second half-shaft 220 refers to the segmented shaft section on the mounting platform 200 that cooperates with the drive unit 500. Specifically, it can be implemented by a cutting structure that is complementary to the first half-shaft 511. The first half-shaft 511 and the second half-shaft 220 are spliced ​​to form a cylindrical structure. The electric slip ring 600 is sleeved at the splicing point of the first half-shaft 511 and the second half-shaft 220, so that the inner wall of the electric slip ring 600 maintains continuous contact with the surface of the spliced ​​shaft. In this embodiment, the mounting platform 200 can maintain its connection with the output shaft 510 of the drive component 500 under the action of gravity and the slip ring 600, without the need for a separate locking structure. This enables rapid assembly of the drive component 500 and the mounting platform 200, while the contact surfaces of the first half-shaft 511 and the second half-shaft 220 can transmit torque.

[0054] This application further proposes that the first conductive structure 210 and the second conductive structure 310 be inserted along the rotation axis direction when the support frame 300 rotates, so that when the support frame 300 rotates with the mounting platform 200, the contact surfaces of the first conductive structure 210 and the second conductive structure 310 always remain overlapping along the axial extension direction. Specifically, this can be achieved by using an axial engagement method of a slot and a pin, so that the contact surface is always in a plane parallel to the axial extension during rotation.

[0055] In the first example of the above embodiments, both the first conductive structure 210 and the second conductive structure 310 are non-rotational bodies. Non-rotational bodies refer to geometric shapes that do not have rotational symmetry around their own axis. Specifically, they can be implemented as cuboids, polygonal prisms, or irregularly shaped cross-section prisms. By breaking rotational symmetry, relative sliding of the contact surfaces is prevented, thereby avoiding poor conductivity caused by contact position offset.

[0056] In the second example of the above embodiment, the central axis of the first conductive structure 210 does not coincide with the rotation axis of the support frame 300. Even if the first conductive structure 210 or the second conductive structure 310 is a cylinder, the contact surface of the first conductive structure 210 and the second conductive structure 310 will maintain a fixed contact area due to eccentricity during rotation, preventing the risk of disconnection caused by circumferential slippage of the contact surface. Specifically, this can be achieved by using an eccentrically arranged cylinder or an asymmetrical structure, so that the contact area of ​​the first conductive structure 210 and the second conductive structure 310 maintains a fixed relative position during rotation.

[0057] Through the above technical solution, this application effectively avoids relative displacement of the contact surfaces of the first conductive structure 210 and the second conductive structure 310 when the support frame 300 rotates, ensuring a stable electrical connection during dynamic rotation. The fixed contact surface position design ensures uniform wear distribution in the conductive area, extending the service life of the first conductive structure 210 and the second conductive structure 310, while maintaining stable contact pressure without the need for an additional pressure adjustment mechanism.

[0058] In some embodiments, the mounting platform 200 includes a first transmission part, which is a structural component disposed on the mounting platform 200 for transmitting driving force and bearing the dynamic load of the support frame 300. Specifically, it can be implemented using a rigid boss with a flat or curved surface, and the surface of the first transmission part forms a load-bearing surface. The support frame 300 includes a second transmission part, which is a structure on the support frame 300 that cooperates with the first transmission part. The second transmission part is in contact with the load-bearing surface. When the support frame 300 rotates, the motion trajectory of the second transmission part forms a trajectory circle centered on the rotation axis of the support frame 300, and the load-bearing surface intersects with the trajectory circle.

[0059] During the rotation of the support frame 300, the second transmission unit moves along a trajectory circle. Since the trajectory circle intersects with the bearing surface of the first transmission unit, the second transmission unit maintains constant contact with the bearing surface. When the drive component 500 drives the mounting platform 200 to rotate, the bearing surface of the first transmission unit applies a force to the second transmission unit through continuous contact, ensuring the stability of torque transmission. Because the bearing surface intersects with the trajectory circle, the second transmission unit will not leave the support range of the bearing surface during rotation, thus avoiding wear or structural failure caused by localized stress concentration at the contact surface. This achieves stable support of the transmission contact surface between the support frame 300 and the mounting platform 200, effectively reducing the risk of vibration due to contact failure during rotation.

[0060] Furthermore, during the assembly process, after the support frame 300 and the mounting platform 200 are inserted along the rotation axis, the second transmission unit is directly embedded into the load-bearing surface coverage area of ​​the first transmission unit, eliminating the need for radial alignment in a confined space and simplifying the installation steps.

[0061] In this application, torque transmission can be achieved by inserting the first conductive structure 210 and the second conductive structure 310 together, or by using the first transmission part and the second transmission part to achieve rotational transmission. When the first transmission part and the second transmission part are present, the positions of the first conductive structure 210 and the second conductive structure 310 are relatively stable, and it is only necessary to achieve contact conductivity. This application does not limit the torque transmission method.

[0062] In some embodiments, the first transmission unit and the second transmission unit are inserted along the rotation axis direction when the support frame 300 rotates to connect the mounting platform 200 and the support frame 300. This eliminates the need to adjust the circumferential angle of the support frame 300 within the narrow mounting cavity 110 during assembly, allowing the operator to directly assemble the support frame 300 and the mounting platform 200 vertically from the top of the display platform 100. Disassembly is achieved by applying a reverse axial tensile force, facilitating the individual replacement of the support frame 300 or the mounting platform 200 during maintenance.

[0063] In some embodiments, please refer to Figure 6 The support frame 300 includes a cover 320, a support rod 330, and a charging structure 340 connected in sequence. The cover 320 has an inner cavity 321. An opening communicating with the inner cavity 321 is formed on the side of the cover 320 away from the support rod 330. The direction of the opening is opposite to the extension direction of the support rod 330, so that the second conductive structure 310 can be pre-installed in the inner cavity 321. The second conductive structure 310 is electrically connected to the charging structure 340, which is used to place the exhibit 2000 and charge the exhibit 2000. When the support frame 300 is assembled with the display platform 100, it is only necessary to insert the first conductive structure 210 of the display platform 100 into the inner cavity 321 of the cover 320 through the opening to form an axial insertion with the second conductive structure 310 to complete the conductive connection, avoiding the difficulty of tool operation caused by space constraints.

[0064] The mounting platform 200 can be pre-assembled as a whole with the drive component 500, or the mounting platform 200 and the drive component 500 can be assembled from the top of the display platform 100 after the drive component 500 is fixed inside the mounting cavity 110. Part of the output shaft 510 of the drive component 500 can extend from the through hole 120, or the first conductive structure 210 can extend from the through hole 120, or the first conductive structure 210 can be located inside the inner cavity 321, as long as the first conductive structure 210 is aligned with the through hole 120. Whether the first conductive structure 210 and the output shaft 510 of the drive component 500 extend into the through hole 120 does not affect the connection of the support frame 300. The cover 320 and the support rod 330 can be an integral structure, or they can be connected by threads or snaps; this embodiment does not limit this.

[0065] Furthermore, a wiring channel 331 is formed within the support rod 330, meaning the support rod 330 adopts a hollow tubular structure. The support rod 330 provides predetermined wiring space for the wires through the internal wiring channel 331. The two ends of the wires are respectively connected to the electrical interface of the charging structure 340 and the second conductive structure 310. During assembly, the wires are pre-inserted into the wiring channel 331 before the support rod 330 is assembled, and the end welding or plugging operation is completed when the support rod 330 is connected to the charging structure 340 and the cover 320.

[0066] Furthermore, by integrating a wiring channel 331 inside the support rod 330, the wires can be laid out within a closed space, preventing the exposed wires from being snagged or worn by external objects and eliminating the risk of external interference.

[0067] In other embodiments, the support rod 330 may also be formed by splicing two parts, both of which may have grooves. When the two parts are spliced, the two grooves are arranged opposite to each other and connected to form a wiring channel 331; or only one part has a groove, and the other part is a cover plate, which covers the opening side of the groove to form the wiring channel 331; this application does not limit this.

[0068] In this case, the inner wall of the wiring channel 331 can also be provided with guide grooves or fixing buckles to prevent the wires from shifting or wearing when the support rod 330 rotates.

[0069] In some embodiments, the top of the display rack 1000 is provided with a retaining edge, which is located around the through hole 120, and the cover 320 is sleeved around the retaining edge. By using the retaining edge structure located outside the display platform 100, the positioning reference of the support frame 300 is transferred from inside the through hole 120 to the external visible area. During assembly, the operator can directly observe the relative position of the cover 320 and the retaining edge without the need for blind operation using auxiliary tools. Furthermore, the sleeve structure between the cover 320 and the retaining edge effectively prevents positional displacement during assembly, ensuring uniform force distribution when the support frame 300 rotates. The annular closed structure formed by the retaining edge further prevents external dust from entering the mounting cavity 110 through the through hole 120, improving the operational reliability of the drive component 500 and the conductive structure.

[0070] The flange refers to the annular protrusion surrounding the through hole 120, which can be achieved by injection molding or metal stamping. Its height can be 3-5mm, and its diameter is slightly larger than that of the through hole 120, serving to provide a radial positioning reference for the cover 320. The cover 320 being fitted around the flange means that the inner wall of the cover 320 and the outer wall of the flange form a clearance fit or transition fit. This can be achieved using a stepped structure. The inner diameter of the cover 320 is set to be 0.1-0.3mm larger than the outer diameter of the flange, ensuring that the cover 320 can move axially along the outer surface of the flange during assembly.

[0071] Specifically, the retaining edge is fixed around the through hole 120 at the top of the display platform 100, forming an annular positioning surface with a defined outer contour. When the cover 320 of the support frame 300 is installed from top to bottom, its inner wall contacts the outer wall of the retaining edge, achieving automatic alignment. Due to the matching relationship between the outer diameter of the retaining edge and the inner diameter of the cover 320, there is no need to adjust the horizontal position of the support frame 300 during installation; positioning can be completed simply by applying pressure in the vertical direction. After assembly, the contact surface between the retaining edge and the cover 320 forms an anti-torsional constraint, preventing the support frame 300 from radially shifting during rotation. At the same time, the contact plane between the top of the retaining edge and the top of the cover 320 forms an axial limit, preventing the support frame 300 from loosening in the vertical direction.

[0072] In some embodiments, the charging structure 340 includes a housing 341, a magnet 342, and a charging pin 343. The housing 341 is connected to a support rod 330 and has a receiving groove for accommodating a portion of the exhibit 2000. The magnet 342 is connected to the housing 341 and is used to attract the exhibit 2000. The charging pin 343 is electrically connected to a second conductive structure 310, passes through the housing 341, and extends into the receiving groove. The charging pin 343 is used to make electrical contact with the exhibit 2000 housed in the receiving groove. The housing 341 and the support rod 330 are directly connected to form an external mounting structure. After the exhibit 2000 is inserted into the receiving groove from the outside, the attraction force generated by the magnet 342 keeps it fixed. The elastic telescopic structure of the charging pin 343 is compressed and contracted when the exhibit 2000 is inserted, and after contact, it adheres tightly to the power supply contact due to its own elasticity. The wiring channel 331 inside the support rod 330 transmits the current from the second conductive structure 310 to the charging pin 343, forming a complete power supply circuit from the external power source to the exhibit 2000.

[0073] In this embodiment, the combination of magnetic fixation and elastic charging pin 343 ensures that the exhibit 2000 maintains stable contact during rotation, avoiding the risk of power outage due to vibration. The charging circuit is fixed through internal wiring of the support rod 330, reducing the risk of wire tangling and improving charging reliability.

[0074] The housing 341 is a shell structure used to fix exhibit 2000. It can be manufactured using injection molding, and a receiving groove on one side accommodates the bottom contour of exhibit 2000. The housing 341 and support rod 330 are connected by threads or snaps for quick assembly and disassembly, avoiding assembly operations inside the display platform 100. The magnet 342 is a magnetic element used to fix exhibit 2000. It can be made of neodymium iron boron material and is fixed to the inner wall of housing 341 by adhesive or embedding. The magnet 342 forms a magnetic attraction with the metal components inside exhibit 2000, preventing exhibit 2000 from detaching during rotation. The charging pin 343 is a conductive component that provides charging contact. It can be made of copper alloy material, with a flexible telescopic structure at the front end. The charging pin 343 passes through the bottom of housing 341 and extends into the receiving groove, forming continuous contact with the power supply contacts of exhibit 2000, ensuring stable current transmission during rotation.

[0075] In some specific embodiments, the depth of the receiving groove can be designed to be one-third of the height of the exhibit 2000 to ensure stability of the center of gravity after embedding. Magnets 342 can be symmetrically arranged on both sides of the inner wall of the chamber 341 to form a symmetrical adsorption force. Magnets 342 can also be set on the side of the chamber 341 away from the receiving groove. The number of charging pins 343 can be set to two, corresponding to the positive and negative contacts of the exhibit 2000 respectively.

[0076] Furthermore, the display rack 1000 may also include a lightbox 710, which is a display device for displaying graphic and textual information. Specifically, it can be implemented using a translucent panel with a built-in light source or an LED screen, conveying relevant information about the exhibit 2000 through text, patterns, or dynamic images. This allows viewers to simultaneously obtain functional descriptions or brand logos of the exhibit 2000.

[0077] The display stand 1000 may also include a mirror 720, which is mounted above the display platform 100 to reflect the images of the exhibit 2000 from different sides as it rotates, expanding the viewing area. It also allows consumers to easily observe the wearing effect of headphones through the mirror 720. The mirror 720 is connected to the top of the lightbox 710 via a damped hinge, allowing the angle of the mirror 720 to be adjusted.

[0078] The display rack 1000 may also include supplementary lighting 730, which refers to a light source component that provides auxiliary lighting. Specifically, it can be an LED array or an adjustable color temperature lamp tube, used to adjust the lighting conditions on the surface of the exhibit 2000. The supplementary lighting 730 is installed on the edge of the display platform 100 through an adjustable structure to project light from multiple angles to eliminate shadows or reflective areas on the surface of the exhibit 2000.

[0079] Through the above solution, this application achieves enhanced information transmission capabilities, expanded visual coverage for the audience, and optimized surface lighting conditions for exhibit 2000 while maintaining the rotating charging function of exhibit 2000. The lightbox 710 visualizes the relevant descriptions of exhibit 2000, the mirror 720 eliminates blind spots, and the supplementary light 730 enhances detail visibility. These three components can be used independently or in combination to adapt to different scenario requirements.

[0080] Furthermore, the top of the display platform 100 can be designed with a mirror effect or made of mirror 720 to enhance the sense of space. At the same time, there is a light guide plate around the outer edge of the display rack 1000 platform to guide light and enhance the aesthetics and attractiveness of the display rack 1000.

[0081] In another embodiment, such as Figure 1 , Figure 2 , Figure 7 and Figure 8 As shown, the support frame 300 is fixed at the required angle after installation. The difference from the above embodiment is that the display rack 1000 may not have a drive component 500.

[0082] In this case, the support frame 300 can still consist of a housing 320, a support rod 330, and a charging structure 340 connected in sequence. In this embodiment, the display rack 1000 may include a reinforcing member 400. The reinforcing member 400 has a first channel 410 and is located at the top of the mounting platform 200. A first conductive structure 210 extends into the first channel 410, the housing 320 is fitted over the outside of the reinforcing member 400, and a second conductive structure 310 extends into the first channel 410 and contacts the first conductive structure 210 for conductivity. In this embodiment, by providing the reinforcing member 400, the strength of the connection between the first conductive structure 210 and the second conductive structure 310 is reinforced. The reinforcing member 400, in cooperation with the housing 320, provides support, reducing the force acting on the connection between the first conductive structure 210 and the second conductive structure 310.

[0083] Since the support frame 300 does not rotate, the back of the support rod 330 can have an opening that communicates with the wiring channel 331, thereby facilitating the installation of wires.

[0084] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention. Furthermore, the embodiments of the present invention and the features thereof can be combined with each other unless otherwise specified.
