无线电力传输技术目前已经开始应用于电视接收终端等领域。 这一技术 的工作原理， 是将发射端和接收端的线圈调校成一个磁共振***， 当发送端 产生的振荡磁场频率和接收端的固有频率相同时， 接收端就产生共振， 从而 实现了能量的传输。 接收端与发射端的线圈的电磁耦合程度， 将直接影响接 收功率的大小， 或者接收端电压的稳定性。 理想的状态是： 发射端与接收端 的线圈同心、 平行且保持适当的距离， 此时收发线圈的磁耦合最紧密， 传输 效率最高。  Wireless power transmission technology has been applied to fields such as television receiving terminals. The working principle of this technology is to adjust the coils of the transmitting end and the receiving end into a magnetic resonance system. When the frequency of the oscillating magnetic field generated by the transmitting end is the same as the natural frequency of the receiving end, the receiving end resonates, thereby realizing energy. transmission. The degree of electromagnetic coupling between the receiving end and the transmitting end coil will directly affect the magnitude of the received power or the stability of the receiving end voltage. The ideal state is: The transmitting end and the receiving end are concentric, parallel and maintain an appropriate distance. At this time, the transmitting coil has the closest magnetic coupling and the highest transmission efficiency.
因此， 如何调整无线电力传输技术中发射端与接收端的位置关系， 成为 业界要解决的一个技术问题。  Therefore, how to adjust the positional relationship between the transmitting end and the receiving end in the wireless power transmission technology has become a technical problem to be solved in the industry.
无尾电视即无线电视就是将无线电力传输技术应用于电视接收终端， 能 够在不借助电线的情况下利用非辐射性磁耦合共振原理实现远距离高效无线 电力传输。  The tailless TV, ie, the wireless television, applies the wireless power transmission technology to the television receiving terminal, and can realize the long-distance high-efficiency wireless power transmission by using the non-radiative magnetic coupling resonance principle without using the electric wire.
在保证了绝对安全的情况下， 无线供电方式将能够有效解决房间布线繁 乱、 家电位置固定化、 居室墙面***座破坏等问题， 为人们的生活提供更多 的便利。 同时， 还将大量节省布线所用的铜、 塑料等材料， 节约了资源， 减 少了污染。  In the case of ensuring absolute safety, the wireless power supply method can effectively solve the problems of messy room wiring, fixed home appliance position, and destruction of the wall of the living room by the socket, and provide more convenience for people's lives. At the same time, it will save a lot of materials such as copper and plastic used for wiring, saving resources and reducing pollution.
同时， 无尾电视釆用无线视频传输技术实现了电视与高清视频设备之间 的信号无线传输， 它能够在 5GHZ频段传输 1080p,、 1080i和 720p等各种高 清信号， 传输有效距离能够超过 100英尺， 信号可以穿墙且延迟不超过 1毫 秒。  At the same time, Tail TV uses wireless video transmission technology to realize wireless signal transmission between TV and HD video equipment. It can transmit various HD signals such as 1080p, 1080i and 720p in the 5GHZ band, and the effective distance can be more than 100 feet. , the signal can pass through the wall and the delay is no more than 1 millisecond.
无尾电视为人们的生活带来了诸多便利， 但是作为无线电力传输技术的 一种应用， 无尾电视同样面临如何将发射端与接收端调整到合适的位置， 以 达到最好的传输效率的问题。 Tail-tail TV brings a lot of convenience to people's lives, but as a wireless power transmission technology In one application, the tailless TV also faces the problem of how to adjust the transmitter and receiver to the appropriate position to achieve the best transmission efficiency.
目前， 无尾电视既可以通过支架挂在墙壁上， 也可以通过底座放置在桌 面上。  Currently, tailless TVs can be hung on a wall by brackets or placed on a table through a base.
图 1是壁挂式无尾电视的安装示意图。 内设发射单元 82的机盒 81预先 被镶嵌在墙壁 80内，再由工作人员将内设接收单元 84的电视 83通过支架 85 挂在墙壁 80外侧， 使得接收单元 84与发射单元 82的位置相对。 传统的支架 安装方式釆用手动调整， 通过使用测量仪器测量发射端输出电压、 电流， 接 收端输入电压、 电流等参数计算出调整后的效率， 然后调整电视支架的左右、 上下以及角度， 然后再次测量相关电气参数， 可能要反复好几次才能最终确 定支架定位。 整个过程因为手工操作而变得异常复杂， 并且这种同心度、 角 度、 距离的调整用人工的方式无法保证每次操作的有效性， 稍有疏忽则前功 尽弃。 该测量过程还容易引起触电， 带来人身安全问题。  Figure 1 is a schematic view of the installation of a wall-mounted tailless television. The casing 81 in which the transmitting unit 82 is provided is previously embedded in the wall 80, and the worker 83 hangs the television 83 having the receiving unit 84 on the outside of the wall 80 through the bracket 85 so that the receiving unit 84 is positioned opposite to the transmitting unit 82. . The traditional bracket installation method uses manual adjustment. By measuring the output voltage, current, receiving input voltage, current and other parameters of the transmitter, the adjusted efficiency is calculated, and then the left and right, up and down and angle of the TV bracket are adjusted, and then again. Measuring the relevant electrical parameters may have to be repeated several times to finalize the positioning of the bracket. The whole process is extremely complicated due to manual operation, and the adjustment of the concentricity, angle, and distance cannot be guaranteed by the manual method, and the slightest negligence is abandoned. The measurement process is also prone to electric shock, which brings personal safety problems.

The television 94 is first placed on the table top 90 through the base 95 of the built-in receiving unit 96, and the box 91 in which the transmitting unit 92 is built is placed on the table top or floor 902 below the table top 90. In this case, the bracket 93 is disposed under the casing 91 of the built-in transmitting unit 92, and the positions of the television 94 and the base 95 are fixed, and the bracket 93 is adjusted by the worker to adjust the left and right, up and down, and angle of the casing 91 to satisfy Maximize transmission efficiency. In this case, the traditional bracket installation method also uses manual adjustment. It is necessary to repeatedly use the measuring instrument to measure the output voltage and current of the transmitting end, the input voltage and current of the receiving end to calculate the adjusted efficiency, and then repeatedly adjust the TV bracket. Left and right, up and down, and angle. The operation is complicated, the effectiveness is poor, and it is also easy to cause electric shock, which brings personal safety problems.

请参照图 3所示， 在本实施例中以壁挂式无尾电视为例， 该无尾电 视包括电视 1和机盒 2 , 接收单元 12设置在电视 1 内， 发射单元 22设 置在机盒 2 内。 为了清楚显示， 该图中的电视 1、 接收单元 12、 机盒 2 以及发射单元 22均未画出厚度， 仅为示意性的显示。机盒 2预先镶嵌在 墙体 （图未示） 内， 在本实施例中， 在镶嵌了机盒 2的墙体外部设置基 准线（图未示）， 该基准线标示出机盒 2在墙体内的左右边缘。 支架（图 未示）设置在电视 1背部， 用于将电视 1挂在镶嵌了机盒 2的墙体上。 在 本发明中， 支架首先被固定在墙体上标示了基准线的位置， 然后再釆用 本发明支架调整装置进行调整。  Referring to FIG. 3, in the embodiment, a wall-mounted tailless television is taken as an example. The tailless television includes a television 1 and a box 2, the receiving unit 12 is disposed in the television 1, and the transmitting unit 22 is disposed in the casing 2. Inside. For the sake of clarity, the television 1, the receiving unit 12, the casing 2, and the transmitting unit 22 in the figure are not shown in thickness, and are merely illustrative. The casing 2 is pre-inlaid in a wall (not shown). In the present embodiment, a reference line (not shown) is disposed outside the wall in which the casing 2 is embedded, and the reference line indicates that the casing 2 is on the wall.

Referring to FIG. 4, a wireless transmitting coil 220 is disposed in the transmitting unit 22, and a power providing unit 221, a power measuring unit 222, and a micro control unit 223 are further disposed. A wireless receiving coil 120 is disposed in the receiving unit 12, and is further provided with a power supply unit 121, a power measuring unit 122, a micro control unit 123, a motor feedback unit 124, and a driving module of the motors M1, M2, and M3.
电力提供单元 221和 121均为电源（Power Supply Unit, PSU ), PSU The power supply units 221 and 121 are both Power Supply Units (PSUs), PSUs.
221和 PSU 121用于将交流电转换为无线发射。功率测量单元（ Power Test Unit , PTU ) 222、 122 包括电压检测以及电流检测电路。 微控制单元 ( Micro-control Unit, MCU ) 223、 123为单片机， 是主控制单元。 电机 反馈单元（ Motor Feedback Unit, MFU ) 124包括限位开关以及检测电路。 The 221 and PSU 121 are used to convert alternating current to wireless transmission. The Power Test Unit (PTU) 222, 122 includes a voltage detection and current detection circuit. The Micro-control Unit (MCU) 223 and 123 are single-chip microcomputers and are the main control unit. The Motor Feedback Unit (MFU) 124 includes a limit switch and a detection circuit.
在发射单元 22内 , PSU 221与 PTU 222之间、 PTU222与 MCU 223 之间， 以及 MCU 223与无线发射线圈 220之间互相连接， 因而均可相互 通讯。 PSU 221与无线发射线圈 220相连， PSU 221可向无线发射线圈 220通讯。  In the transmitting unit 22, the PSU 221 and the PTU 222, the PTU 222 and the MCU 223, and the MCU 223 and the wireless transmitting coil 220 are connected to each other, and thus can communicate with each other. The PSU 221 is coupled to a wireless transmit coil 220 that can communicate with the wireless transmit coil 220.
在接收单元 12内 , PSU 121与 PTU 122之间、 PTU122与 MCU 123 之间， 以及 MCU 123与无线发射线圈 120之间互相连接， 因而均可相互 通讯。 PSU 121与无线接收线圈 120相连， PSU 121可向无线接收线圈 120通讯。  In the receiving unit 12, the PSU 121 and the PTU 122, the PTU 122 and the MCU 123, and the MCU 123 and the wireless transmitting coil 120 are connected to each other, and thus can communicate with each other. The PSU 121 is coupled to the wireless receive coil 120, which can communicate with the wireless receive coil 120.
如图 4所示，无线发射线圈 222与无线接收线圈 120之间通过电磁耦合 连接， 进行由无线发射线圈 222到无线接收线圈 120的单向无线电力传输 和双向无线通讯。 该双向无线通讯信号流程如下：  As shown in FIG. 4, the wireless transmitting coil 222 and the wireless receiving coil 120 are connected by electromagnetic coupling to perform one-way wireless power transmission and two-way wireless communication from the wireless transmitting coil 222 to the wireless receiving coil 120. The two-way wireless communication signal flow is as follows:
首先， 由 MCU 123解析由安装人员通过遥控器或其他控制装置发出 的调整指令， 例如该指令是将电视 1沿 X轴向右侧移动， 则 MCU 123输出 驱动脉冲至电机 M2驱动模块 , 由电机 M2驱动模块驱动电机 M2转动 , 使 支架带动电视 1沿 X轴向右侧移动。 在支架带动电视 1沿 X轴向右侧移动的过程中， MCU 123将其检测电 同时， MCU 123将由 PTU 122测量并且反馈的即时接收功率 Pr以及由 PTU 222测量并且反馈， 然后由无线发射线圈 220发送的即时发射功率 Pt 通过公式 First, the MCU 123 analyzes the adjustment command issued by the installer through the remote controller or other control device. For example, the command moves the TV 1 along the X axis to the right, and the MCU 123 outputs a drive pulse to the motor M2 drive module. The M2 drive module drives the motor M2 to rotate, causing the bracket to drive the television 1 to move to the right along the X axis. During the movement of the carriage 1 to move the television 1 to the right in the X-axis, the MCU 123 detects it while the MCU 123 will be measured by the PTU 122 and fed back the instantaneous received power Pr as well as measured and fed back by the PTU 222, and then by the wireless transmitting coil 220 transmitted instantaneous transmit power Pt by formula
η =Pr/Pt x 100% W式 得出即时电源传输效率 η , 并且将该即时电源传输效率 η实时显示 在电视屏幕上， 使得安装人员能够非常直观的看到其发出指令的调整效 果。  η =Pr/Pt x 100% W gives the instant power transmission efficiency η and displays the instant power transmission efficiency η on the TV screen in real time, allowing the installer to see the adjustment effect of the command.
在即时传输效率 η最大时， 接收单元 12所处的位置即是最佳位置， 再由安装人员发出指令， 由 MCU 123控制电机 Μ2反转或者停止。  When the instantaneous transmission efficiency η is maximum, the position at which the receiving unit 12 is located is the optimum position, and then the installer issues an instruction to control the motor Μ2 to reverse or stop by the MCU 123.
安装人员可以以同样的过程发出指令， 由 MCU 123解析后控制电机 Ml或者 Μ3转动或者停止， 从而使支架带动电视 1沿 Z轴移动或者相对镶 嵌有机盒 2的墙面转动，最终使接收单元 12相对于发射单元 22处于最佳的 接收位置。  The installer can issue commands in the same process, and the MCU 123 analyzes and controls the motor M1 or Μ3 to rotate or stop, so that the bracket drives the TV 1 to move along the Z axis or rotate relative to the wall of the embedded organic box 2, and finally the receiving unit 12 is rotated. It is in an optimal receiving position with respect to the transmitting unit 22.
可以理解， 也可以预先将软件程序写入 MCU 123 和 MCU 223 , 在 MCU 123收到并且解析由安装人员通过遥控器或其他控制装置发出的调 整指令后启动程序， 由程序控制 MCU 123发出提示， 该提示可显示在电 视屏幕上， 再由安装人员依照提示发出指令进行调整。 上述程序控制的 流程图如图 5所示。  It can be understood that the software program can also be written into the MCU 123 and the MCU 223 in advance, and after the MCU 123 receives and analyzes the adjustment instruction issued by the installer through the remote controller or other control device, the program is started, and the program control MCU 123 issues a prompt. The prompt can be displayed on the TV screen, and then the installer can follow the prompts to make adjustments. The flow chart of the above program control is shown in Figure 5.
应用本发明支架调整装置还可以釆用一键自动调整的方式。 釆用这 种方式进行调整时， 安装人员或者用户只要通过遥控器或其他控制装置 发出一键调整指令， MCU 123和 MCU 223即可通过预先编写在内的程 序自动调整。 在本实施例中， MCU 123先驱动电机 Ml , 以无线电力传 输的效率最大化为依据调整接收单元 12和发射单元 22之间的垂直距离， 在调整过程中记录效率最大的一点固定； 然后 MCU123驱动电机 M2 , 调整接收单元 12相对于发射单元 22沿 X轴的位移， 记录效率最大的一 点固定； 最后 MCU 123驱动电机 M3 , 调整接收单元 12相对于发射单 元 22的转动角度 γ , 记录效率最大的一点固定。 这样， 本发明支架调整 装置就完成了一键自动调整过程。 当然， 在本发明支架调整装置的一键 自动调整过程中，也可以将 MCU 123实时计算出来的即时传输效率 η实 时显示在电视屏幕上， 并且该一键自动调整过程也可以通过安装人员或 者用户发出的指令终止。 The bracket adjusting device of the present invention can also adopt a one-button automatic adjustment mode.釆 When adjusting in this way, the installer or user can issue a one-button adjustment command via the remote control or other control device, and the MCU 123 and MCU 223 can be automatically adjusted by a pre-programmed program. In this embodiment, the MCU 123 first drives the motor M1 to adjust the vertical distance between the receiving unit 12 and the transmitting unit 22 based on the maximum efficiency of wireless power transmission, and the recording efficiency is fixed at the maximum point during the adjustment process; then MCU123 The driving motor M2 adjusts the displacement of the receiving unit 12 along the X axis with respect to the transmitting unit 22, and the recording efficiency is fixed at a maximum point; finally, the MCU 123 drives the motor M3 to adjust the receiving unit 12 relative to the emission list. The rotation angle γ of the element 22 is fixed at the point where the recording efficiency is the largest. Thus, the bracket adjusting device of the present invention completes the one-button automatic adjustment process. Of course, in the one-button automatic adjustment process of the bracket adjusting device of the present invention, the real-time transmission efficiency η calculated by the MCU 123 in real time can also be displayed on the television screen in real time, and the one-button automatic adjustment process can also be performed by the installer or the user. The issued command is terminated.
当然， 应用本发明支架调整装置可以釆用的一键自动调整方式的调 整顺序不限于此， 也可以以其它顺序进行调整。  Of course, the adjustment sequence of the one-button automatic adjustment method that can be applied by the bracket adjusting device of the present invention is not limited thereto, and may be adjusted in other orders.
在上述调整过程中， MFU 124实时将电机的运动情况， 包括运行距 离以及是否运动到极限位置等信息反馈给 MCU 123。 如果 MFU 124检 测到电机已经运行到极限位置， 则 MCU 123 自动停止该方向的电机运 动。 在安装人员分步骤调整的模式， MCU 123还可将电机运行到极限位 置的信息显示在电视屏幕上。 在一键调整的模式， MCU 123可按程序命 令该电机反转， 继续调整。  During the above adjustment process, the MFU 124 feeds back information about the motor's motion, including the running distance and whether it is moving to the extreme position, to the MCU 123 in real time. If the MFU 124 detects that the motor has reached the limit position, the MCU 123 automatically stops the motor movement in that direction. In the installer's step-by-step mode, the MCU 123 also displays information about the motor running to the extreme position on the TV screen. In the one-key adjustment mode, the MCU 123 can program the motor to reverse and continue to adjust.
图 6是 MFU 124反馈电路的原理图。 如图 6所示， 仅以电机 Ml为 例进行说明， 在该电路中设有限位开关 SQ1、 SQ2 , 光耦器件 Dl、 D2 以及若干电阻 Rl、 R2、 R3、 R4等。 限位开关 SQ1为常开开关， 光耦器 件 D1不导通， 电压 VS1通过 R2上拉到控制芯片工作电压 Vcc后高电平 输出， 此时 MCU 123正常输出时钟信号 CP与方向信号 DR至电机 Ml 驱动模块控制电机 Ml工作，带动支架沿 Z轴向接近发射单元 22的方向 运动， 当支架运动到极限位置时， 限位开关 SQ1关闭， 光耦器件 D1导 通， VS1低电平输出至 MCU 123 , 此后 MCU 123 关闭 CP输出， 电机 Ml停止转动， 支架停止运动。 同理， SQ2为常开开关， 光耦器件 D2不 导通， VS2为高电平输出， 此时 MCU 123正常输出时钟信号 CP与方向 信号 DR至电机 Ml驱动模块控制电机 Ml工作， 带动支架沿 Z轴向远 离发射单元 22 的方向运动， 当支架运动到极限位置时， 限位开关 SQ2 关闭， 光耦器件 D2导通， VS2低电平输出至 MCU 123 , MCU 123关闭 CP输出， 电机 Ml停止转动， 支架停止运动。 Figure 6 is a schematic diagram of the MFU 124 feedback circuit. As shown in FIG. 6, only the motor M1 is taken as an example. In the circuit, limit switches SQ1 and SQ2, optocoupler devices D1 and D2, and a plurality of resistors R1, R2, R3, and R4 are provided. The limit switch SQ1 is a normally open switch, and the optocoupler device D1 is not turned on. The voltage V S1 is pulled up to the control chip operating voltage V cc after R2 is pulled up, and the MCU 123 normally outputs the clock signal CP and the direction signal DR. The motor M1 drive module controls the motor M1 to work, and drives the bracket to move in the direction of the Z-axis approaching the firing unit 22. When the bracket moves to the limit position, the limit switch SQ1 is turned off, the optocoupler device D1 is turned on, and V S1 is low. Output to the MCU 123, after which the MCU 123 turns off the CP output, the motor M1 stops rotating, and the carriage stops moving. Similarly, SQ2 is a normally open switch, the optocoupler device D2 is not conducting, and V S2 is a high level output. At this time, the MCU 123 normally outputs the clock signal CP and the direction signal DR to the motor M1 drive module to control the motor M1 to operate, and the bracket is driven. Moving along the Z axis away from the transmitting unit 22, when the bracket moves to the limit position, the limit switch SQ2 is turned off, the optocoupler device D2 is turned on, the V S2 low level is output to the MCU 123, and the MCU 123 turns off the CP output, the motor Ml stops rotating and the bracket stops moving.
电机 M2和电机 M3的限位原理与电机 Ml相同， 在此不再赘述。 图 7是上述限位过程的程序控制流程图。 请参照图 8所示， 在本发明支架调整装置应用于底座式无尾电视的 实施例中， 该无尾电视包括底座 3和机盒 2，， 接收单元 12， 设置在电视 底座 3内， 发射单元 22， 设置在机盒 2， 内。 为了清楚显示， 该图中的 底座 3、 接收单元 12，、 机盒 2， 以及发射单元 22， 均未画出厚度， 仅为 示意性的显示。 电视 （图 8未示出） 及其底座 3放置在桌面 （图 8未示 出） 上。 内设发射单元 22， 的机盒 2， 放置在桌面下方， 正对电视底座 3的位置。 在本实施例中， 支架 （图 8未示出）设置在机盒 2， 底部， 用 于调整机盒 2， 及其内的发射单元 22， 相对于设置在底座 3内的接收单元 12' 的位置。 The limit principle of the motor M2 and the motor M3 is the same as that of the motor M1, and will not be described here. Figure 7 is a flow chart showing the program control of the above limit process. Referring to FIG. 8 , in the embodiment in which the bracket adjusting device of the present invention is applied to a pedestal tailless television, the tailless television includes a base 3 and a casing 2 , and the receiving unit 12 is disposed in the television base 3 and is launched. The unit 22 is disposed inside the casing 2. For the sake of clarity, the base 3, the receiving unit 12, the casing 2, and the transmitting unit 22 in the figure are not shown in thickness, and are merely illustrative. A television (not shown in Fig. 8) and its base 3 are placed on a table top (not shown in Fig. 8). The casing 2, in which the firing unit 22 is built, is placed under the table top, facing the position of the television base 3. In the present embodiment, a bracket (not shown in FIG. 8) is disposed at the bottom of the casing 2 for adjusting the casing 2, and the transmitting unit 22 therein, with respect to the receiving unit 12' disposed in the base 3. position.
在该第二实施例中， 在该支架上同样设置有三个步进电机 Ml、 M2、 In this second embodiment, three stepping motors M1, M2 are also provided on the bracket.
M3。 通常， 放置电视的桌面为水平平面， 内设接收单元 12， 的底座 3 也是水平放置。 在这里， 将机盒 2' 上与水平面平行且相互垂直的两个 方向 （机盒 2， 相对于底座 3移动的前后方向以及左右方向） 分别定义 为 Y轴和 X轴， 将与水平面垂直的方向定义为 Z轴 （如图 8所示）。 在 本实施例中， 通过将内设发射单元 22， 的机盒 2， 放置在桌面下方， 正 对电视底座 3的位置的限位基本可以保证内设发射单元 22， 的机盒 2， 在 Y轴方向 （即前后方向） 相对内设接收单元 12， 的底座 3的同心度。 电机 Ml用于调整发射单元 22， 与接收单元 12， 之间的距离， 亦即调整 内设发射单元 22， 的机盒 2， 在 Z轴方向上的位移。 电机 M2用于调整 发射单元 22， 与接收单元 12， 在 X轴上的同心度， 亦即调整内设发射 单元 22， 的机盒 2， 在 X轴方向上的位移。 电机 M3用于调整发射单元 22， 与接收单元 12， 之间的角度 γ 。 M3. Usually, the desktop on which the television is placed is a horizontal plane, and the base 3 with the receiving unit 12 is also placed horizontally. Here, the two directions of the casing 2' parallel to the horizontal plane and perpendicular to each other (the casing 2, the front-rear direction and the left-right direction relative to the base 3) are defined as the Y-axis and the X-axis, respectively, which are perpendicular to the horizontal plane. The direction is defined as the Z axis (as shown in Figure 8). In this embodiment, by placing the box 2 with the transmitting unit 22 disposed under the table top, the position of the position of the TV base 3 can substantially ensure that the box 2 of the transmitting unit 22 is provided, in Y. The axial direction (i.e., the front-rear direction) is relatively concentric with respect to the base 3 of the receiving unit 12. The motor M1 is used to adjust the distance between the transmitting unit 22 and the receiving unit 12, that is, the displacement of the casing 2 of the internal transmitting unit 22 in the Z-axis direction. The motor M2 is used to adjust the concentricity of the transmitting unit 22 and the receiving unit 12 on the X-axis, that is, the displacement of the casing 2 of the built-in transmitting unit 22 in the X-axis direction. The motor M3 is used to adjust the angle γ between the transmitting unit 22 and the receiving unit 12.
图 9是在第二实施例中， 本发明支架调整装置的原理框图。 请参照 图 9所示， 在发射单元 22， 内同样设有无线发射线圈 220 , 还设有 PSU 221、 PTU 222以及 MCU 223。 在接收单元 12， 内也同样设有无线接收 线圈 120 , 还设有 PSU 121、 PTU 122以及 MCU 123。 上述元件以及它 们之间的通讯方式也与第一实施例中相同。 第二实施例与第一实施例的 不同之处在于， 由于支架设置在内设发射单元 22， 的机盒 2， 底部， 所 以电机反馈单元 124 以及电机 Ml、 Μ2、 Μ3 的驱动模块不是设置在接 收单元 12， 内， 而是设置在发射单元 22， 内。 Figure 9 is a schematic block diagram of a stent adjusting device of the present invention in a second embodiment. Referring to FIG. 9, the transmitting unit 22 is also provided with a wireless transmitting coil 220, and is further provided with a PSU 221, a PTU 222, and an MCU 223. A wireless receiving coil 120 is also provided in the receiving unit 12, and a PSU 121, a PTU 122, and an MCU 123 are also provided. The above elements and the manner of communication therebetween are also the same as in the first embodiment. The second embodiment is different from the first embodiment in that, since the bracket is disposed at the bottom of the casing 2, which is provided with the transmitting unit 22, the motor feedback unit 124 and the driving modules of the motors M1, Μ2, Μ3 are not disposed at Connect The receiving unit 12, inside, is disposed in the transmitting unit 22.
如图 9所示，无线发射线圈 222与无线接收线圈 120之间通过电磁耦合 连接， 进行由无线发射线圈 222到无线接收线圈 120的单向无线电力传输 和双向无线通讯， 该双向无线通讯信号流程如下：  As shown in FIG. 9, the wireless transmitting coil 222 and the wireless receiving coil 120 are electromagnetically coupled to perform one-way wireless power transmission and two-way wireless communication from the wireless transmitting coil 222 to the wireless receiving coil 120. The two-way wireless communication signal flow as follows:
首先， 由 MCU 123解析由安装人员通过遥控器或其他控制装置发出 的调整指令， 例如该指令是将机盒 2' 沿 X轴向右侧移动， 则 MCU 123通 过无线接收线圈 120和无线发射线圈 220将该指令传送到 MCU 223 , 再由 MCU 223输出驱动脉冲至电机 M2驱动模块 , 由电机 M2驱动模块驱动电 机 M2转动， 使支架带动机盒 2' 沿 X轴向右侧移动。  First, the MCU 123 parses an adjustment command issued by the installer through the remote controller or other control device, for example, the command moves the case 2' along the X-axis to the right, and the MCU 123 passes the wireless receiving coil 120 and the wireless transmitting coil. 220 transmits the command to the MCU 223, and the MCU 223 outputs a drive pulse to the motor M2 drive module, and the motor M2 drives the module drive motor M2 to rotate, so that the bracket with the drive case 2' moves to the right along the X axis.
在支架带动机盒 2' 沿 X轴向右侧移动的过程中， MCU 223将其检测 电路检测到的电机 M2带动的支架运动机构的参数通过无线发射线圈 220 和无线接收线圈 120传送到 MCU 123 , 再由电视屏幕显示出来。  During the movement of the carriage with the motorized case 2' along the X-axis right side, the MCU 223 transmits the parameters of the carriage movement mechanism driven by the motor M2 detected by the detection circuit to the MCU through the wireless transmitting coil 220 and the wireless receiving coil 120. , then displayed by the TV screen.
同时， MCU 123将由 PTU 122测量并且反馈的即时接收功率 Pr以及由 PTU 222测量并且反馈， 然后由无线发射线圈 220发送的即时发射功率 Pt 通过公式  At the same time, the MCU 123 will measure the instantaneous received power Pr measured by the PTU 122 and the feedback and feedback by the PTU 222, and then transmit the instantaneous transmit power Pt transmitted by the wireless transmitting coil 220 through the formula.
η =Pr/Pt x 100% W式 得出即时电源传输效率 η , 并且将该即时电源传输效率 η实时显示 在电视屏幕上， 使得安装人员能够非常直观的看到其发出指令的调整效 果。  η =Pr/Pt x 100% W gives the instant power transmission efficiency η and displays the instant power transmission efficiency η on the TV screen in real time, allowing the installer to see the adjustment effect of the command.
在即时传输效率 η最大时，发射单元 22， 所处的位置即是最佳位置， 再由安装人员发出指令，由 MCU 123通过无线接收线圈 120和无线发射线 圈 220将该指令传送到 MCU 223 , 再由 MCU 223控制电机 Μ2反转或者停 止。  When the instant transmission efficiency η is maximum, the location of the transmitting unit 22 is the optimal position, and then the installer issues an instruction, and the MCU 123 transmits the command to the MCU 223 through the wireless receiving coil 120 and the wireless transmitting coil 220. The MCU 223 then controls the motor Μ2 to reverse or stop.
安装人员可以以同样的过程发出指令， 控制电机 Ml或者 Μ3转动或 者停止， 从而使支架带动机盒 2， 沿 Z轴移动或者相对放置有底座 3的桌 面转动， 最终使发射单元 22， 相对于接收单元 12， 处于最佳的接收位置。  The installer can issue commands in the same process to control the motor M1 or Μ3 to rotate or stop, so that the bracket with the motorized box 2 moves along the Z axis or relative to the table on which the base 3 is placed, and finally the transmitting unit 22, relative to the receiving Unit 12 is in the best receiving position.
同样的， 也可以预先将软件程序写入 MCU 123和 MCU 223 , 在 MCU 123收到并且解析由安装人员通过遥控器或其他控制装置发出的调整指 令后启动程序， 由程序控制 MCU 123发出提示， 该提示可显示在电视屏 幕上， 再由安装人员依照提示发出指令进行调整。 上述程序控制的流程 图如图 5所示。 Similarly, the software program can also be written to the MCU 123 and the MCU 223 in advance, and the adjustment finger issued by the installer through the remote controller or other control device is received and parsed at the MCU 123. After the program is started, the program control MCU 123 issues a prompt, which can be displayed on the TV screen, and then the installer issues an instruction to adjust according to the prompt. The flow chart of the above program control is shown in FIG. 5.
在第二实施例中同样可以以釆用一键自动调整的方式。 与第一实施 例不同的是由 MCU 223而不是 MCU 123驱动电机进行调整。  In the second embodiment, it is also possible to automatically adjust by one button. Unlike the first embodiment, the motor is driven by the MCU 223 instead of the MCU 123 for adjustment.
可以理解， 在第二实施例中 MFU 124不是将信息反馈给 MCU 123 , 而是反馈给 MCU 223。 其反馈过程以及反馈电路原理则与第一实施例中 相同。 第二实施例中的限位过程的程序控制流程也与第一实施例中相同 同。  It can be understood that in the second embodiment, the MFU 124 does not feed back information to the MCU 123, but feeds back to the MCU 223. The feedback process and the feedback circuit principle are the same as in the first embodiment. The program control flow of the limit process in the second embodiment is also the same as in the first embodiment.
本发明支架调整装置主要由单片机通过接收单元接收安装人员对各 种参数的控制命令， 分析并控制支架的动作， 可简单、 迅速、 安全并且 准确地调整接收单元和发射单元的相对位置， 从而保证在上述两者间最 佳的传输效率。在电机运行过程中 MCU不断扫描 MFU反馈的电机状态 , 同时 MCU不断扫描接收单元反馈的即时效率，从而保证整个无线电力传 输设备的可靠、 快捷并且稳定的工作。 本发明支架调整装置还可以一键 自动完成上述所有工作，从而使并非专业安装人员的普通用户在需要时， 也可以通过一健控制， 完成对支架的调整， 使无尾电视或者其它无线电 力传输设备达到最佳的使用效果。  The bracket adjusting device of the invention mainly receives the control command of the installer on various parameters through the receiving unit, analyzes and controls the action of the bracket, and can adjust the relative positions of the receiving unit and the transmitting unit simply, quickly, safely and accurately, thereby ensuring The best transmission efficiency between the two. During the operation of the motor, the MCU continuously scans the motor state of the MFU feedback, and the MCU continuously scans the instantaneous efficiency of the feedback from the receiving unit to ensure reliable, fast and stable operation of the entire wireless power transmission device. The bracket adjusting device of the invention can also automatically complete all the above work with one button, so that an ordinary user who is not a professional installer can also complete the adjustment of the bracket through a health control when needed, so that the tailless television or other wireless power transmission The device achieves the best results.
可以理解， 本发明支架调整装置不仅可以应用于无尾电视， 也可以 应用于应用无线电力传输技术， 并且需要调整发射端和接收端的对位， 从而 得到较佳传输效率的其它各种显示类或者监控类无线电力传输设备， 例如摄 像头等等。 本发明支架调整装置的电机驱动模块以及相应的电机可以不 是三组， 而是四组， 即有一组电机驱动模块和电机用于调整支架在上述 实施例中沿 Y轴的位移。 同样， 本发明支架调整装置的电机驱动模块以 及相应的电机也可以是一组或者两组， 即仅调整支架一个或者两个方向 的平移或者转动。 本发明支架调整装置可以将支架调整的方向不限于上 述实施例中提到的方向。 在本发明支架调整装置中， 也可以省去电机反 馈单元 MFU。  It can be understood that the bracket adjusting device of the present invention can be applied not only to the tailless television but also to the application of the wireless power transmission technology, and needs to adjust the alignment between the transmitting end and the receiving end, thereby obtaining other various display classes with better transmission efficiency or Monitoring wireless power transmission equipment, such as cameras and the like. The motor drive module and the corresponding motor of the bracket adjusting device of the present invention may be not three groups, but four groups, that is, a set of motor drive modules and motors for adjusting the displacement of the bracket along the Y-axis in the above embodiment. Similarly, the motor drive module of the bracket adjusting device of the present invention and the corresponding motor may also be one or two sets, i.e., only the translation or rotation of the bracket in one or two directions is adjusted. The bracket adjusting device of the present invention can adjust the direction of the bracket adjustment to the direction mentioned in the above embodiment. In the bracket adjusting device of the present invention, the motor feedback unit MFU can also be omitted.
