Description of the invention α) [Technical field to which the invention belongs]-The present invention relates to a transmission device capable of automatically shifting motion, in particular, it controls a switching gear position in a transmission device through a torque feedback device, The gears in the transmission device are then switched by this switching gear, so that when the load torque increases or decreases, the speed reduction of the power transmission device can be automatically switched. [Previous technology] The conventional power transmission device, especially as an electric rotary power tool (such as a φ electric drill, electric screwdriver, etc.), which has a multi-speed transmission in the power tool device, usually uses a reduction mechanism to provide multi-speed transmission. Or multiple segments of torque. Generally, this type of stall mechanism is mainly composed of an array planetary gear mechanism, which controls the internal clutch or some driving mechanism through a manual mechanism, so that certain components in each gear train are fixed or certain components are driven by Driven, thus achieving the effect of different input and output reduction ratios. [Summary of the Invention] — "Technical Issues to Be Solved" In the aforementioned reduction mechanism of the conventional power transmission device, it is subjective to be performed by the user through his use experience or by observing the processing conditions during operation. After the judgment, the gear position of the deceleration mechanism can be manually changed to achieve a sufficient torque or speed. The torque, speed, power loss and mechanical efficiency of the drive motor of a general reduction mechanism have a certain relationship. The loss power and mechanical efficiency usually increase as the product of torque and speed increases.

Description of the invention (2) Until the product of torque and speed reaches a certain value, the power loss will continue to increase, but the mechanical efficiency will gradually decrease. However, through manual operation: control often does not properly make the operation of the drive motor fall within the range of the best mechanical efficiency. Therefore, a mechanism capable of feeding back the load torque is required to automatically switch the gear position of the speed reduction mechanism, and the present invention is based on the lack of a speed reduction mechanism of a conventional power transmission device for creation. "Technical Means for Solving the Problem" About the present invention, an automatic transmission power transmission device is provided to practically solve one or even several of the aforementioned related technologies. In order to achieve the above object, the present invention provides an automatic transmission power transmission device, which is mainly composed of a hollow casing and a transmission device and a torque feedback device which are sequentially installed in the body, and is characterized in that the torque feedback The device has an intermeshing thrust wheel and a sliding ring, and has a set of rings to cooperate with the seat body to restrain a compression spring around the outer ring of the seat. The thrust wheel is subject to a torsion force fixed to the outer edge of the seat. The spring acts to restrict its rotation angle. The sliding ring is confined in the seat and can only move up and down. The transmission device is composed of a switching gear formed by an internal gear structure. It is composed of two planetary gear sets. A concave groove is formed around the outer ring of the switching gear. By inserting several pins into the ring groove of the switching gear through the aforementioned collar, the switching gear can be restricted to be in the first extreme position while engaging two sets of planetary gear sets at the same time, or the switching gear can be restricted to be in the second The extreme position engages only its second planetary gear set. Therefore, if the load torque received by the aforementioned thrust wheel is insufficient to overcome the resistance of the torsion spring and the compression spring, the switching gear will be at

200300719 五、發明說明（3) 第一極限位置，並同時嚙合此兩組星式齒輪組且隨其同步旋 轉。若前述之推力輪受到夠大之負載扭力（而足以克服該扭 力彈簧及壓縮彈簧之抵抗時，其會產生自轉並透過其嚙合之 斜面推動該滑動環，使得該滑動環壓掣該切換齒輪移動，使 得該切換齒輪處於第二極限位置且和該座體内底部之凸緣卡 合而無法旋轉，。故本發明可自動變速之動力傳輸裝置可在負 載扭力增加或降低時，自動切換動力傳輸裝置之減速機構， 而達到自動變換擋位，且提昇動力傳輸裝置之機械效率者。200300719 V. Description of the invention (3) The first limit position, and simultaneously mesh the two star gear sets and rotate synchronously with them. If the aforementioned thrust wheel receives a large enough load torque (and is sufficient to overcome the resistance of the torsion spring and the compression spring), it will rotate and push the sliding ring through its meshing inclined surface, so that the sliding ring presses the switching gear to move So that the switching gear is in the second extreme position and is engaged with the flange on the bottom of the seat body so that it cannot rotate. Therefore, the power transmission device capable of automatically changing speed can automatically switch the power transmission when the load torque increases or decreases. The speed reduction mechanism of the device can automatically change gears and improve the mechanical efficiency of the power transmission device.
