[0032] The connecting turntable 120 refers to the structure connecting the turntable 110 and the conductive slip ring 130.

[0033] In some embodiments, as shown in Figure 1 , the connecting turntable 120 is arranged on the lower part 112 of the turntable, and the turntable 110 is connected with the conductive slip ring 130 through the connecting turntable 120. For more information about the conductive slip ring 130, please refer to the relevant description below. Figure 1

[0034] Figure 2 is an exemplary structure diagram of the connecting turntable according to some embodiments of the present specification.

[0035] As shown in Figure 2 , the connecting turntable 120 comprises an upper connecting turntable 121 and a lower hollow ring 122. For more information about the lower hollow ring 122, please refer to Figure 4 and the related description.

[0036] The upper connecting turntable 121 refers to the partial structure of the connecting turntable. For example, the upper connecting turntable 121 can be a disc or the like. In some embodiments, as shown in Figure 2 ​​​​As shown, the upper connecting turntable 121 includes an upper connecting turntable first part 121-1 and an upper connecting turntable second part 121-2. Among them, the upper connecting turntable second part 121-2 is in contact with the conductive slip ring 130; the upper connecting turntable first part 121-1 is the upper part of the upper connecting turntable second part 121-2 and a structure extending to the periphery.

[0037] In some embodiments, the turntable 110 can be fixedly connected with the upper connecting turntable 121 in various ways. For example, the turntable 110 can be fixedly connected with the upper connecting turntable 121 by a limiting device or other mechanical connection means.

[0038] In some embodiments, the lower part of the turntable 110 is provided with a limiting buckle (not shown in the figure), and the upper connecting turntable 121 can be fixedly connected with the turntable 110 through the limiting buckle.

[0039] The limiting buckle refers to a buckle for connecting the turntable 110 and the connecting turntable 120. For example, the limiting buckle can include a rotating locking buckle and a threaded buckle, etc. In some embodiments, the number of limiting buckles can include at least two. For example, the number of limiting buckles can be two, four or more, etc. The number of limiting buckles can be set in advance according to different needs.

[0040] In some embodiments, the limiting buckles can be distributed around the lower half of the turntable 110.

[0041] In some embodiments, the upper connecting turntable first part 121-1 can be fixedly connected with the lower part 112 of the turntable through a plurality of limiting buckles to form a limiting installation. Among them, the limiting installation refers to an installation method for fixedly connecting the upper connecting turntable 121 and the turntable 110 together through the limiting buckles, so as to limit the displacement or disengagement of the upper connecting turntable 121 during rotation, etc.

[0042] In some embodiments, the upper connecting turntable first part 121-1 is provided with a plurality of corresponding buckle matching parts, which can be matched with a plurality of limiting buckles on the lower part of the turntable 110. The upper connecting turntable first part 121-1 can be fixedly connected with the turntable 110 by inserting the card slot of the limiting buckle and clamping, thereby forming the fixed connection between the upper connecting turntable 121 and the turntable 110. Among them, the inner diameter size of the plurality of limiting buckles is slightly larger than the outer diameter size of the upper connecting turntable first part 121-1, so as to allow slight displacement during installation. After the upper connecting turntable first part 121-1 is inserted into the limiting buckle, the locking device of the buckle will automatically clamp or lock the upper connecting turntable first part 121-1, so as to ensure that it will not be loosened during rotation.

[0043] In some embodiments of the present specification, the connecting turntable and the turntable are stably connected through the limiting buckle to prevent the connecting turntable from shaking up and down or sliding left and right, etc., resulting in the problem of falling off.

[0044] In some embodiments, the upper connecting turntable 121 can transmit rotary power. For example, when the turntable 110 rotates, the connecting turntable 120 is driven to rotate.

[0045] In some embodiments of the present specification, the turntable is fixedly connected with the upper connecting turntable 121, which can ensure the stability of the turntable during rotation, avoid eccentricity or uneven force distribution during rotation of the turntable, and ensure that the connecting turntable is driven to rotate during rotation of the turntable.

[0046] The conductive slip ring 130 refers to an electrical component that facilitates the provision of power to the exhibited product through a wire during rotation of the turntable.

[0047] In some embodiments, the conductive slip ring 130 is arranged at the lower part of the connecting turntable 120.

[0048] Figure 3 is an exemplary structural diagram of the conductive slip ring according to some embodiments of the present specification.

[0049] In some embodiments, as shown in Figure 3 The conductive slip ring 130 includes an inner ring 131 and an outer ring 132, and the inner ring 131 can rotate relative to the outer ring 132. The conductive slip ring is composed of two parts: rotating and stationary. The rotating part is connected with the connecting turntable 120 and rotates with the connecting turntable 120, which is called "inner ring 131". The stationary part is connected with the fixed structure of the pressing plate, which is called "outer ring 132".

[0050] In some embodiments, the conductive slip ring is mainly composed of elastic materials (such as brushes, etc.), sliding contact surface materials (conductive rings, precision small steel bearings, insulating plastic materials, resin adhesive materials), etc. The brush is made of precious metal alloy material, which is symmetrically contacted with the "V" and "concave" grooves of the conductive ring in the shape of "II". The elastic pressure of the brush and the ring groove sliding contact of the conductive ring are used to transmit signals and currents, etc., thereby connecting the inner ring and the outer ring for conduction.

[0051] In some embodiments, the inner ring 131 can rotate relative to the outer ring 132, which includes that when the turntable 110 rotates, the inner ring 131 of the conductive slip ring can be driven by the connecting turntable 120 to rotate synchronously with the turntable 110. The outer ring 132 of the conductive slip ring remains stationary. For synchronous rotation, please refer to the relevant description below. Figure 1

[0052] The inner ring 131 is a rotatable part in the conductive slip ring 130.

[0053] ​In some embodiments, the inner ring 131 of the conductive slip ring 130 can be connected to the connecting turntable 120. More about how the inner ring 131 of the conductive slip ring 130 is connected to the connecting turntable 120 can be found in Figure 4 and the description thereof.

[0054] In some embodiments, when the turntable 110 rotates, the rotating power can be transmitted to the conductive slip ring 130 through the connecting turntable 120, driving the inner ring 131 of the conductive slip ring 130 to rotate synchronously with the turntable 110, so as to ensure that the wires do not entangle.

[0055] In some embodiments, the connecting turntable 120 comprises a lower hollow ring 122, and the inner ring 131 is fixedly sleeved outside the lower hollow ring 122. More about this can be found in Figure 4 and the description thereof.

[0056] The wire refers to a cable used for transmitting electric current. For example, the wire can be a coaxial cable, a high-flexibility cable, a multi-core cable, etc. Among them, the type and length of the wire can be pre-set by the technician according to different needs.

[0057] In some embodiments, the wire comprises a first wire and a second wire, and the first wire and the second wire are part of the wire.

[0058] The first wire is part of the wire used for transmitting electric power for the products displayed on the turntable 110.

[0059] In some embodiments, the power transmitted by the first wire can be pre-adjusted and set based on the power demand of the exhibition products, so as to ensure that the power demand of different products is adapted.

[0060] In some embodiments, the inner ring 131 is connected to the first wire, and the first wire is connected to the turntable 110. For example, the first wire is fixed on the inner ring 131 through a pre-set wire routing route, and the wire end of the first wire sequentially passes through the connecting turntable 120 and the turntable 110, is led out and connected to the upper part 111 of the turntable, so as to supply power to the products. The connection mode of the first wire, the inner ring 131, the connecting turntable 120 and the turntable 110 can be fixed connection, that is, the relative positions of the first wire, the inner ring 131, the connecting turntable 120 and the turntable 110 do not change when the exhibition device rotates to display the products.

[0061] In some embodiments, the first wire can transmit electric power in various ways. For example, the first wire can be directly connected to the power interface of the displayed product, or the first wire can be fixed at a fixed position on the turntable 110 through a socket, and the product is powered through the socket, etc.

[0062] In some embodiments, the first wire is connected to the rotating disc 110 through the connecting disc 120 and rotates synchronously with the connecting disc 120 and the rotating disc 110.

[0063] Synchronous rotation refers to the rotation of the connecting disc 120, the rotating disc 110, the inner ring 131 of the conductive slip ring 130, and the first wire at the same rotational speed and direction. Synchronous rotation can ensure that the relative positions between the connecting disc 120, the rotating disc 110, the inner ring 131 of the conductive slip ring, and the first wire remain fixed and do not shift or twist during rotation.

[0064] In some embodiments, the first wire can be drawn out from the lower hollow annular ring 122, pass through the upper connecting disc 121 and the rotating disc 110, and be connected to the upper part 111 of the rotating disc to transmit power for displaying products. For the description of the lower hollow annular ring 122, please refer to Figure 2 and the related description.

[0065] In some embodiments, the connection of the first wire to the rotating disc further includes that a technician can set a through hole or a wire channel at a preset position of the connecting disc 120 and the rotating disc 110 to enable the first wire to pass through and be connected to the upper part of the rotating disc. The preset position can be set in advance according to different needs.

[0066] In some embodiments of the present specification, by connecting the first wire to the rotating disc through the connecting disc, since the inner ring, the connecting disc, and the rotating disc rotate synchronously, the first wire also rotates synchronously, ensuring that the relative positions between the connecting disc, the rotating disc, the inner ring of the conductive slip ring, and the first wire remain fixed, thereby avoiding the problem of winding of the first wire.

[0067] The outer ring 132 is a part of the conductive slip ring that does not move.

[0068] The second wire is a part of the wire that connects the outer ring 132 to the power source.

[0069] In some embodiments, the second wire is connected to the power source. The outer ring 132 connects the second wire, which is connected to the power source through the second wire.

[0070] The power source refers to an external power source that provides power for the exhibition device 100 to realize the electrification of the rotating disc.

[0071] In some embodiments, by connecting to the power source through the second wire, the power of the power source is transmitted along the second wire and transmitted from the outer ring 132 to the inner ring 131 through the preset wire routing route inside the conductive slip ring and the conductive connection between the outer ring 132 and the inner ring 131. The inner ring 131 can transmit power to the rotating disc 110 through the first wire to ensure continuous transmission of power.

[0072] The preset wire routing refers to a fixed line or channel preset for the wire in the conductive slip ring in the design of the exhibition device 100 capable of achieving power supply to the rotating disc.

[0073] In some embodiments, the second wire can be connected to the power source in various ways. For example, the end of the second wire can be equipped with a plug that can be directly plugged into a power socket to complete the connection with the power source. For another example, the outer ring part of the conductive slip ring can be equipped with a fixing device for connecting the wire, and the second wire can be fixed to the output end of the power source by screws or spring clips.

[0074] In some embodiments of the present specification, the connection of the second wire to the power source can provide a stable power source for the exhibition device capable of achieving power supply to the rotating disc, ensuring that the displayed product can continuously obtain power during the rotating display.

[0075] In some embodiments, as shown in Figure 1 The exhibition device capable of achieving power supply to the rotating disc 100 further includes a roller 140, a base 150, and a pressing plate 160. The roller 140 is arranged at the lower part of the rotating disc, the base 150 is arranged at the lower part of the roller 140, and the pressing plate 160 is arranged at the lower part of the base 150.

The number of rollers can be preset according to actual needs, for example, the number of rollers is 10, 20, etc.

[0077] The base 150 refers to a component that does not rotate and serves as a support. A stable support platform is provided by the base 150 to ensure the normal operation and safe use of other components (such as the roller 140, the rotating disc 110, etc.).

[0078] The pressing plate 160 refers to a structure that does not rotate and is arranged at the lower part of the base 150.

[0079] In some embodiments, the pressing plate 160 can be fixedly connected with the base 150 in various ways (such as a screw locking method, etc.). The tight connection between the pressing plate 160 and the base 150 can fix or clamp other components (such as the rotating disc, the roller, etc.), preventing the components from moving or loosening during operation, etc.

[0080] In some embodiments, the roller 140 is arranged at the lower part of the connecting turntable, the base 150 is arranged at the lower part of the roller 140, and the pressing plate 160 is arranged at the lower part of the base 150.

[0081] In some embodiments, the outer ring 132 of the conductive slip ring can be fixedly connected with the pressing plate 160 in various ways, such as screwing, etc.

[0082] In some embodiments, the outer ring 132 of the conductive slip ring can also be fixedly connected with the pressing plate 160 in other ways, such as welding, etc.

[0083] In some embodiments of the present specification, a stable support structure is formed by arranging the roller at the lower part of the connecting turntable and installing the base thereunder. The outer ring of the conductive slip ring is fixedly connected with the pressing plate, and this design enables continuous and stable transmission of power and signals to the products and other equipment on the turntable during rotation of the turntable.

[0084] In some embodiments, as shown in Figure 1 the exhibition device 100 capable of realizing power supply to the turntable further comprises a fixing member 170, a central shaft 180, and a bearing member 190. The central shaft 180 penetrates the pressing plate 160, the conductive slip ring 130, and the connecting turntable 120 in sequence, and is fixedly connected with the pressing plate 160, the conductive slip ring 130, and the connecting turntable 120 by cooperating with the fixing member 170; the bearing member 190 is arranged between the fixing member 170 and the connecting turntable 120.

As shown in Figure 1 the fixing member 170 is located at the center of the turntable 110 and is connected with the central shaft 180. The fixing member can be of various types, for example, the fixing member can be a screw, etc.

[0086] The central shaft 180 is a component that penetrates the entire exhibition device 100 capable of realizing power supply to the turntable. As shown in Figure 1 the central shaft 180 can be located at the center of the entire exhibition device and penetrates the entire exhibition device.

[0087] In some embodiments, as shown in Figure 1 the central shaft penetrates the pressing plate, the conductive slip ring, and the connecting turntable in sequence.

[0088] The bearing member 190 refers to a component for supporting and reducing friction between the central shaft 180 and the fixing member 170 or the connecting turntable 120. In some embodiments, as shown in Figure 1As shown, the bearing member 190 can be located between the fixed member and the connecting turntable. The inner ring of the bearing member 190 is unable to rotate and serves as a fixed member. The outer ring of the bearing member 190 is connected to the turntable 110 and the connecting turntable 120, respectively, and rotates to reduce friction.

[0089] In some embodiments, the bearing member 190 transmits load by rolling or sliding, significantly reducing frictional resistance and energy loss during rotation, thereby protecting components from wear.

[0090] In some embodiments, the fixed member 170, through cooperation with the central shaft 180 and other related components (such as the turntable 110, the connecting turntable 120, etc.), achieves stable fixation of the platen 160, the conductive slip ring 130, and the connecting turntable 120 through the cooperation and precise docking of multiple components.

[0091] In some embodiments of the present specification, the central shaft serves as a key component that passes through the platen, the conductive slip ring, and the connecting turntable. Through the cooperation of the fixed member, a stable overall structure is formed between the above-mentioned components. This structure significantly enhances the structural stability of the exhibition device, enabling it to withstand greater loads and impacts, thereby improving the safety and reliability of the exhibition device.

The rotation speed of the turntable 110 can be set by default by the main control chip and / or pre-set by a technician according to requirements.

[0095] In some embodiments, the rotation speed of the turntable 110 can include multiple gears. For example, the rotation speed gears include low gear, medium gear, and high gear, etc. The rotation speed gears of the turntable can be set by default by the main control chip and / or pre-set by a technician according to requirements to adapt to different display requirements.

[0096] In some embodiments, the main control chip can be integrated into the exhibition device 100 that can realize power supply to the turntable.

[0097] The motor refers to a device that drives the rotation of the turntable 110. For example, the motor can include one of a direct current motor (DC Motor), a brushless motor (Brushless DC Motor), and a stepper motor (Stepper Motor).

[0098] In some embodiments, the rotating disc 110 can drive the motor by the battery. For example, after the motor receives the power provided by the battery, it can convert the electric energy into mechanical energy to generate rotating force.

[0099] In some embodiments of the present specification, different application scenarios and different exhibition products may require different rotating speeds. By controlling the rotating speed of the rotating disc through the master control chip, the rotating speed of the rotating disc can be more in line with the actual demand, thereby improving the flexibility of the exhibition device 100 that can realize the power-on of the rotating disc.

[0100] In some embodiments of the present specification, the rotating power is transmitted to the conductive slip ring through the connecting rotating disc, which drives the inner ring of the conductive slip ring to rotate synchronously with the rotating disc, which can avoid the problem of wire winding, ensure the normal operation of the product, and improve the coherence of the display effect, thereby increasing the safety of the product during rotation.
