Description

Technical Field

[0001] The utility model relates to the technical field of wireless charging, and more specifically, to a multi-device wireless tracking and charging table. Background Art

[0002] With the development of society, electronic devices are becoming increasingly important to our lives. The increase in the number of electronic devices has brought about charging problems. However, the existence of charging cables will cause the desktop to be cluttered and unsightly, storage to be difficult, charging positions to be limited, cables to be worn and aged, and so on. Therefore, wireless charging technology has become the focus of research today.

[0003] A wireless charging table is a table with a wireless charging coil installed under it. It uses visual recognition and embedded control technology to locate and move the charging coil under the device being charged. However, current wireless charging tables require a predetermined area for the charging coil to charge multiple devices, which limits the placement of desktop electronic products and results in wasted coil space. For example, patent number CN116131405A discloses a wireless charging mechanism and a wireless charging table mat. The mechanism comprises a frame, a slide mounted on the frame, a charging coil assembly, and a first drive assembly for driving the slide and the charging coil assembly to reciprocate in a first direction. The slide comprises a slider, an annular flexible circuit board mounted on the slider, and a second drive assembly for driving the flexible circuit board in a second direction perpendicular to the first direction. The flexible circuit board is provided with a positioning assembly and a charging assembly. The positioning assembly senses the magnetic element of the device being charged, and the charging assembly and the charging coil assembly are used to wirelessly charge the device. The charging coil assembly has a predetermined width along the first direction that is greater than or equal to the width of two devices being charged. This wireless charging mechanism can provide point-to-point power to multiple devices being charged at arbitrary locations within a large area. However, in this patent, in order to charge multiple devices, the charging coil needs to have a preset area. When multiple devices are too far apart, the area of ​​the coil will become very large, resulting in waste. Utility Model Content

[0004] The purpose of the present utility model is to overcome the deficiency of the prior art wireless charging mechanism that the charging coil requires a preset area, and to provide a multi-device wireless tracking charging table, in which each coil tracks one device separately, thereby reducing coil waste.

[0005] In order to solve the above technical problems, the technical solution adopted by the present invention is:

[0006] A multi-device wireless tracking and charging table is provided, comprising a table top, a first translation device, a second translation device, a third translation device, a charging device, a box installed at the bottom of the table top, table legs installed at the bottom of the box, and a sensing device arranged on the table top, wherein the first translation device, the second translation device, the third translation device and the charging device are all located inside the box, the first translation device is fixed to the inner bottom surface of the box, there are no less than two second translation devices, the second translation device is fixed to the output end of the first translation device, the third translation device can be fixed to the output end of one or more of the second translation devices, the charging device can be fixed to the output end of the second translation device or the output end of the third translation device, the translation direction of the second translation device is perpendicular to the translation direction of the first translation device on the horizontal plane, the translation direction of the third translation device is parallel to the translation direction of the first translation device, and the sensing device is used to sense the position of the device to be charged.

[0007] The utility model discloses a multi-device wireless tracking charging table, wherein the table legs support a box body, and the box body is covered with a table top on which people can study or work. The first translation device, the second translation device, the third translation device and the charging device are all located in the box body, and the overall design is simple and beautiful. When the device to be charged is placed on the table, the sensing device will identify the position of the device to be charged and convert it into an electrical signal, controlling the first translation device and the second translation device to translate along their translation directions, so that the charging device is located below the device to be charged, thereby wirelessly charging the device to be charged. When multiple devices need to be charged, the second translation device may be restricted by another second translation device along its translation direction. At this time, the third translation device will be activated, so that the charging device fixed to the output end of the third translation device will translate along the translation direction of the first translation device, and the charging device will be moved below the device to be charged to avoid being restricted. Through the cooperation of the first translation device, the second translation device and the third translation device, multiple devices can be charged, thereby achieving charging coverage of the entire table top. Each coil tracks one device separately, and there is no need to preset the area of ​​the coil, thereby reducing waste.

[0008] Furthermore, the interior of the box is divided into at least two workspaces along the translation direction of the first translation device, and each of the workspaces is provided with at least one slide mechanism, each of which includes a first slider, a first screw, a first polished rod parallel to the first screw, a first driving member fixed to the bottom surface of the box, and two first support plates fixed to the bottom surface of the box. One end of the first screw is fixedly connected to the output end of the first driving member, and the other end is rotatably connected to one of the first support plates. The two ends of the first polished rod are respectively fixedly connected to the two first support plates. The first slider is threadedly connected to the first screw and slidably connected to the first polished rod. The rotation of the first driving member drives the rotation of the first screw, and the first polished rod provides a guiding effect, so that the first slider can only perform linear motion and does not rotate. The slide mechanism operates smoothly and with high precision, so the positioning of the charging device is also more accurate. The desktop is divided into two workspaces, and each slide mechanism charges the device in that space separately, so that the slide mechanism has a shorter travel and saves time.

[0009] Furthermore, each of the slide mechanisms includes two first polished rods, and each of the first screw rods and the two first polished rods are distributed in a triangular pattern in the radial direction. The triangular pattern provides stability, and this arrangement makes the operation of the first slider more stable.

[0010] Furthermore, the box further includes two slide rails disposed parallel to the inner bottom surface of the box body, with slide rail blocks mounted on the slide rails in sliding connection with the slide rails. The slide rails are parallel to the first screw rod, which is located between the two slide rails. The slide rail blocks are fixedly connected to the second translation device. The cooperation between the slide rails and the slide rail base provides guidance and support for the first slider, making the operation of the first slider more stable.

[0011] Furthermore, the second translation device includes a translation plate, a second slider, a second driving member, a second screw, a second polished rod, and two second support plates fixed to the top of the translation plate. The second driving member is fixed to the top of the translation plate. One end of the second screw is fixedly connected to the output shaft of the second driving member, and the other end is rotatably connected to one of the second support plates. The two ends of the second polished rod are respectively fixedly connected to the two second support plates. The second driving member is a rotating driving member. The second polished rod is parallel to the second screw. Each second screw and the two second polished rods are distributed in a triangular shape in the radial direction. The second slider is threadedly connected to the second screw and slidably connected to the second polished rod. The third translation device or the charging device is fixed to the top of the second slider. The second translation device is also a screw slide mechanism with smooth operation. The second screw is driven to rotate by the second driving member. The second polished rod serves as a guide, causing the second slider to move linearly, thereby driving the third translation device or the charging device fixed to the top of the second slider to move.

[0012] Furthermore, the third translation device includes a bracket and a third drive member fixed to the bracket. The bracket is fixed to the top of the second slider, and the third drive member is used to drive the charging device to translate along the bracket. When there are multiple devices to be charged and the movement of the second translation devices is blocked, the third drive member can drive the charging device to move in the translation direction of the first translation device, thereby preventing the devices from being unable to charge normally due to the restriction between the second translation devices.

[0013] Furthermore, the third translation device further includes a guide rod mechanism, comprising a rocker fixedly connected to the output shaft of the third driver, a guide rail fixed to the top of the bracket, a sliding block slidably connected to the guide rail, and a guide sleeve rotationally connected to the sliding block and slidably connected to the rocker. The third driver is a rotary driver, and the charging device is fixed to the top of the sliding block. The third driver drives the rocker to rotate, and the guide sleeve is both slidably connected to the rocker and rotatably connected to the sliding block, thereby converting the rotational motion of the rocker into linear motion of the sliding block, thereby causing displacement of the charging device fixedly connected to the sliding block.

[0014] Furthermore, the charging device includes a coil and a coil frame, wherein the coil is fixed to the top of the coil frame by magnetic attraction, and the coil frame is fixed to the top of the sliding block or the top of the second slider. The magnetic attraction facilitates the disassembly and assembly of the coil and allows for regular replacement.

[0015] Furthermore, the device includes a desk lamp mounted on top of the table top, and the sensing device includes a camera mounted on the desk lamp, which is used to locate the charging device. The desk lamp can provide lighting, and the camera is mounted on the desk lamp, with the wiring located inside the desk lamp housing, making the overall design more aesthetically pleasing and less obtrusive. The camera can capture the desktop and identify the location of the device to be charged.

[0016] Furthermore, a long, parallel-to-horizontal cable trough is provided on one side of the box. Because the charging device and the driver require power, the box contains a large number of cables. This trough ensures that the cables move synchronously with the guide rail mechanism, preventing cable entanglement.

[0017] Compared with the prior art, the beneficial effects of the present invention are:

[0018] 1. Through the cooperation of the first translation device, the second translation device and the third translation device, multiple devices can be charged, thereby achieving full desktop charging coverage. Each coil tracks a device separately, without the need to preset the coil area, reducing waste;

[0019] 2. Both the first translation device and the second translation device are slide mechanisms, which have better stability and accuracy;

[0020] 3. The camera setting can capture the situation on the desktop and identify the location of the device to be charged. BRIEF DESCRIPTION OF THE DRAWINGS
