When the charging base is plugged into the table card shell, the plug and socket are connected, which is convenient and quick.

[0015] Preferably, the top of the charging base is provided with a wireless charging receiver module, which is electrically connected to the energy storage module.

[0016] By adopting the above technical solution, when charging is needed, simply place the charging base into the charging cabinet. At this time, the wireless charging transmitter module and the wireless charging receiver module inside the charging cabinet will approach and make contact, realizing wireless charging, which is convenient and fast.

[0017] Secondly, in order to facilitate charging of the charging base, this application provides a charging cabinet.

[0018] The charging cabinet provided in this application adopts the following technical solution:

[0019] A charging cabinet includes a cabinet body with multiple charging compartments for placing charging bases. A wireless charging transmitter module is installed at the top of each charging compartment and connected to a power source. A switch assembly is installed on the inner wall of each charging compartment to disconnect or connect the wireless charging transmitter module to the power source.

[0020] By adopting the above technical solution, when charging is needed, simply place the charging base into the charging compartment. At this time, the wireless charging transmitter module and the wireless charging receiver module inside the charging compartment will approach and contact each other to achieve wireless charging, which is convenient and fast.

Detailed Implementation

[0036] The present application will be further described in detail below with reference to all the accompanying drawings.

[0037] This application discloses a rechargeable conference seating display. (See also...) Figure 1 , Figure 2 A rechargeable conference seating display board includes a table cover 100, which is triangular prism in shape. The table cover 100 is provided with a display module 200 and an input module 300. There are two display modules 200, which are respectively disposed on the two parallelogram sides of the table cover 100. The input module 300 is located on the side of the table cover 100 on which one display module 200 is installed. The input module 300 is electrically connected to a controller via a line, and the display module 200 is electrically connected to the controller via a line. A charging base 400 for charging the input module 300 and the display module 200 is detachably connected to the bottom of the table cover 100.

[0038] The input module 300 uses a touch screen, and the display module 200 uses a display screen. The touch screen is used to output text signals according to the user's operation, and the controller is used to receive the text signals and control the display screen to display the text input by the user. The controller can be a microcontroller.

[0039] The bottom of the table case 100 is bolted with two insert blocks 110. The top of the charging base 400 has two slots 410. The insert blocks 110 are inserted into the slots 410 in a vertical direction. The charging base 400 is equipped with a first locking component, which includes a first spring 510, a locking block 520, a locking pin 530, and a pull block 540. The charging base 400 has two locking grooves 420 that communicate with the two slots 410 respectively. The two locking grooves 420 are horizontally arranged. The locking block 520 is slidably connected to the locking grooves 420 in a horizontal direction. The 0 is a cuboid. The insert 110 has a groove 120 on its side wall near the locking slot 420. When the locking block 520 slides, it is inserted into the groove 120. The top of the locking block 520 is provided with a sloping guide surface. When the insert 110 is inserted into the slot 410, the bottom of the insert 110 abuts against the guide surface. One end of the locking pin 530 is threaded to the locking block 520. The bottom wall of the locking slot 420 has a sliding hole. The other end of the locking pin 530 passes through the sliding hole and is threaded to the pull block 540 outside the charging base 400. The central axes of the locking block 520, the locking pin 530 and the pull block 540 are all on the same straight line.

[0040] The charging base 400 contains an energy storage module, which can be a lithium battery. A plug 710 is installed at the bottom of the table case 100, and a socket 720 is embedded at the top of the charging base 400. The plug 710 and the socket 720 cooperate with each other. The plug 710 is electrically connected to the input module 300, the display module 200, and the controller through a conversion circuit. The conversion circuit can be a voltage or current conversion circuit to adjust the voltage and current. The socket 720 is electrically connected to the energy storage module. When the plug 110 is fully inserted into the slot 410, the plug 710 is fully inserted into the socket 720. When the plug 710 is inserted into the socket 720, the energy storage module supplies power to the input module 300, the display module 200, and the controller.

The voltage regulation circuit is used to adjust the rectified DC voltage for use by the energy storage module. The rectifier circuit usually includes a rectifier and a filter.

[0042] The implementation principle of a rechargeable meeting seat display board according to an embodiment of this application is as follows: When a meeting is held, staff can input the name of the person in the seat through the input module 300, and then display the name through the display module 200, so that the meeting board can be reused, thereby saving resources; in addition, its charging base 400 is detachable, and when charging is needed, staff only need to remove the charging base 400 and put it in the charging cabinet for charging, which is convenient and quick.

[0043] This application discloses a charging cabinet. (Refer to...) Figure 2 , Figure 3 A charging cabinet includes a cabinet body 800, with multiple charging compartments 900 opened on one side of the cabinet body 800. The charging compartments 900 are arranged horizontally and are divided into multiple groups. Each group of charging compartments 900 is arranged horizontally and the multiple charging compartments 900 are arranged vertically. A wireless charging transmitter module 910 is embedded in the inner top wall of the charging compartment 900. The wireless charging transmitter module 910 is connected to a power source, which provides power to the wireless charging transmitter module 910.

[0044] The wireless charging transmitter module 910 includes a switching power supply module, an oscillator circuit, a power amplifier, and a transmitter coil. The power supply is connected to the input terminal of the switching power supply module. The output of the switching power supply module is electrically connected to the transmitter coil through the oscillator circuit and the power amplifier in sequence. The switching power supply module is used to convert the mains power into the voltage or current required by the transmitter coil. The oscillator circuit includes a high-frequency oscillator, which is used to convert DC power into a high-frequency AC signal. Commonly used oscillator types include square wave oscillators or sine wave oscillators. The power amplifier is used to amplify the AC signal output by the oscillator to drive the transmitter coil and ensure that it generates an effective electromagnetic field.

[0045] The transmitting and receiving coils utilize resonant circuits with the same resonant frequency to achieve uniform inductance parameters and improve energy transfer efficiency. Employing electromagnetic coupling, the alternating magnetic field generated by the transmitting coil is coupled to the non-contact receiving coil of the load, thus enabling contactless energy transfer between the power source and load. Specifically, energy is transferred through magnetic field resonance between the transmitting and receiving coils. This method features long transmission distances, high transmission power and efficiency, and is generally unaffected by spatial obstacles.

[0046] Additionally, a switch assembly is provided between the wireless charging transmitter module 910 and the power supply. This switch assembly is used to disconnect or connect the wireless charging transmitter module 910 and the power supply. The switch assembly includes an abutment block 921, a connecting post 922, a conductive plate 923, a first contact point 924, a second contact point 925, and a second spring 926. Both the abutment block 921 and the conductive plate 923 are cuboid in shape. One end of the connecting post 922 is threaded to the abutment block 921, and the other end is threaded to the conductive plate 923. The central axes of the abutment block 921, the connecting post 922, and the conductive plate 923 are on the same straight line. A sliding groove 930 is provided inside the cabinet 800. A sliding hole 940 communicating with the sliding groove 930 is provided on the inner wall of the charging compartment 900 away from its opening. The abutment block 921 is slidably connected to the inner wall of the charging compartment 900, and the sliding direction is the length direction of the charging compartment 900. The connecting post 922 is slidably connected to the sliding hole 940. The conductive plate 923 is slidably connected to the sliding groove 930. The second spring 926 is slidably connected. One end of the second spring 926 is bonded to the inner wall of the sliding groove 930 away from the sliding hole 940, and the other end of the second spring 926 is bonded to the conductive plate 923. The opening of the charging compartment 900 is larger than the width of the charging base 400 to facilitate the insertion of the two pulling blocks 540. When the charging base 400 is inserted into the charging compartment 900, the side wall of the charging base 400 contacts the abutment block 921. The first contact point 924 and the second contact point 925 are both connected to the inner wall of the sliding groove 930 away from the sliding hole 940 by bolts. The first contact point 924 is electrically connected to the power supply, and the second contact point 925 is electrically connected to the wireless charging transmitter module 910. When the conductive plate 923 slides, it contacts the first contact point 924 and the second contact point 925. At this time, the wireless charging transmitter module 910 is connected to the power supply. The inner wall of the charging compartment 900 away from its opening has an embedding hole that communicates with the sliding hole. When the charging base 400 is fully inserted into the charging compartment 900, the abutment block 921 enters the embedding hole.

[0047] Additionally, a second locking element is provided inside the charging case 900 to lock the position of the charging base 400. The second locking element includes a magnetic layer 950 (see reference). Figure 1 The magnetic layer 950 is bolted to the side wall of the charging base 400, and the magnet 960 is bolted to the inner wall of the charging compartment 900 away from the opening. The magnet 960 is located on both sides of the embedded hole. The conductive plate 923 is bolted to the side away from the abutment block 921 with an insulating rod 970. The insulating rod 970 is set in a horizontal direction. The other end of the insulating rod 970 passes through the bottom wall of the sliding groove 930 and is bolted to a pressing block 980. The pressing block 980 is located outside the cabinet 800. After the charging base 400 is charged, the staff can use the pressing block 980 to separate the magnetic layer 950 from the magnet 960.

[0048] The implementation principle of a charging cabinet in this application embodiment is as follows: When charging is required, simply place the charging base 400 into the charging compartment 900. At this time, the wireless charging transmitter module 910 and the wireless charging receiver module 600 in the charging compartment 900 approach and contact each other to achieve wireless charging, which is convenient and fast, and multiple charging bases 400 can be charged at the same time; the connection between the wireless charging transmitter module 910 and the power supply can also be disconnected or connected by the switch assembly.

[0049] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
