配合参考图1，各该拍面部30相对远离该握柄12的一侧定义一部分沿该框壁11延伸的主拍击区域32，于该拍具1的一长度方向上，各该主拍击区域32的一延伸长度为一该拍面部30的一最大长度的2/3，该感测单元40设于该二拍面部30的该主拍击区域32之间，借此可获得该主拍击区域32的该加速度数据及该角速度数据，进而可推算该拍具的挥击角度、路径、持拍时间等各项相关数据。With reference to Figure 1, each racket portion 30 defines a main striking area 32 extending along the frame wall 11 on a side relatively away from the handle 12. In a length direction of the racket 1, an extension length of each main striking area 32 is 2/3 of a maximum length of the racket portion 30. The sensing unit 40 is disposed between the main striking areas 32 of the two racket portions 30, thereby obtaining the acceleration data and the angular velocity data of the main striking area 32, and further calculating various related data such as the swing angle, path, and holding time of the racket.
该弹性支撑结构20为一发泡填充物或一立体网架，具有足够的结构强度且重量轻，有助于该 拍具1的轻量化而能轻巧敏捷地操作使用；各该拍面部30的一平均硬度大于该弹性支撑结构20的一平均硬度，可保持各该拍面部30平整、回弹力佳以提供良好的击球效果。于本实施例中，该弹性支撑结构20为一发泡填充物，例如但不限为PU、EVA、PE或PVA等材质制成，重量轻且成本低，亦可通过发泡密度的调整、材料选用来改变该弹性支撑结构20的软硬度及弹性，以符合不同使用需求；该多个通道21的数量与各该拍面部30的该多个贯孔31的数量相同，可有效降低空气阻力，且该多个贯孔31使各该拍面部30非连续延伸，而可与被拍击物于每次拍击时的接触状态存在不同的可能性；该二拍面部30之间距不小于2厘米，结构强度佳、可吸震，且便于配置该感测单元40的各元件。然，该多个通道的数量亦可多于各该拍面部的该多个贯孔的数量，以利轻量化。The elastic support structure 20 is a foam filler or a three-dimensional grid, which has sufficient structural strength and is light in weight. The racket 1 is lightweight and can be operated lightly and swiftly; the average hardness of each racket portion 30 is greater than the average hardness of the elastic support structure 20, which can keep each racket portion 30 flat and have good resilience to provide a good hitting effect. In this embodiment, the elastic support structure 20 is a foam filler, such as but not limited to PU, EVA, PE or PVA, which is light and low in cost. The hardness and elasticity of the elastic support structure 20 can also be changed by adjusting the foam density and selecting materials to meet different usage requirements; the number of the multiple channels 21 is the same as the number of the multiple through holes 31 of each racket portion 30, which can effectively reduce air resistance, and the multiple through holes 31 make each racket portion 30 extend non-continuously, so that there are different possibilities for the contact state with the object being hit each time; the distance between the two racket portions 30 is not less than 2 cm, the structural strength is good, shock absorption can be achieved, and it is convenient to configure the components of the sensing unit 40. However, the number of the plurality of channels may also be greater than the number of the plurality of through holes of each of the flap portions to facilitate weight reduction.
较佳地，该拍具1另包括一连接于该感测单元40与该传输单元50之间的处理单元60，该处理单元60包括一计时模块61及一储存模块62，该处理单元60可基于该计时模块61的一时间信息依时序将该加速度数据及该角速度数据储存于该储存模块62，借此可将使用者的操作动作、顺序完整地储存纪录，再借由该传输单元50即时地、非周期性地或周期性地输出至该外部装置。该外部装置例如但不限包括手机、电脑、云端伺服器、平板电脑等，便于读取该加速度数据及该角速度数据以利分析，据以修正、调整该使用者的挥拍动作。Preferably, the racket 1 further includes a processing unit 60 connected between the sensing unit 40 and the transmission unit 50, the processing unit 60 includes a timing module 61 and a storage module 62, the processing unit 60 can store the acceleration data and the angular velocity data in the storage module 62 in a time sequence based on a time information of the timing module 61, thereby the user's operation action and sequence can be completely stored and recorded, and then output to the external device in real time, non-periodically or periodically through the transmission unit 50. The external device includes, for example but not limited to, a mobile phone, a computer, a cloud server, a tablet computer, etc., which is convenient for reading the acceleration data and the angular velocity data for analysis, and correcting and adjusting the user's swing action accordingly.
该传输单元50包括一蓝牙传输模组51、一ANT+传输模组52、一红外线传输模组及一无线射频传输单元至少其中一者，可依需求配置、选用，便于操作。该拍具1另包括一供电单元70，例如但不限为蓄电池或一次性电池，该供电单元70电性连接该感测单元40、该处理单元60及该传输单元50以供给电力。 The transmission unit 50 includes at least one of a Bluetooth transmission module 51, an ANT+ transmission module 52, an infrared transmission module and a wireless radio frequency transmission unit, which can be configured and selected according to needs for easy operation.
