Abstract: A transmission structure of a hub motor has a hub shell, an axle, a motor unit, and a clutch assembly. The clutch assembly connects with the hub shell and the motor unit, and includes a driving ring, an output disc, a fixing base, a clutch disc, and a pressing ring. The motor unit drives the driving ring to rotate. The output disc is capable of driving the hub shell to rotate. The driving ring drives the clutch disc to rotate and further drives the pressing ring; the pressing ring then pushes the clutch disc to contact the output disc and further drives the output disc to rotate. The fixing base is magnetic and is disposed between the output disc and the motor unit. The clutch disc is magnetically attractable such that the clutch disc separates from the output disc when the motor unit stops working to prevent the motor unit from providing resistance.

Abstract: A stamping quality inspection system includes a stamping device, a signal detecting element, and a processor. The signal detecting element is coupled to the stamping device. The signal detecting element is configured to detect a sound signal and a vibration signal of the stamping device. The processor is coupled to the signal detecting element. The processor is configured to determine a stamping operation time interval according to the sound signal and the vibration signal, to compare a sub sound signal of the sound signal and a sub vibration signal of the vibration signal in the stamping operation time interval to a pattern comparison module, so as to generate a quality inspection result.

Abstract: An adjusting method is implemented by a control system and is used to adjust a multi-axis robotic arm including a plurality of motors. The adjusting method includes following operations. A decay rate of each motor is analyzed by the control system. When the decay rate of one of the motors exceeds a corresponding first threshold, a residual value of the one of the motors is further analyzed by the control system. When the residual value exceeds a first default value, an output capacity of at least one of the motors is adjusted by the control system.

Abstract: The invention provides a stacked structure comprising a master circuit board and at least two slave circuit boards. The master circuit board comprises a plurality of connecting seats. Each slave circuit board is equipped with a connector, and defined with a plurality of post-production process areas. Wherein the connector of each slave circuit board is disposed on one of post-production process areas, and inserted into the corresponding connecting seat. When the connector of the slave circuit board must be through other slave circuit boards in order to insert the corresponding connecting seat, the post-production process areas that are disposed on other slave circuit boards and impede the connection between the connector and the corresponding connecting seat will be cut into hollow areas. Accordingly, the connector of the slave circuit board is capable of inserting the corresponding connecting seat through the hollow areas of other slave circuit boards.

Abstract: The invention provides a M.2 interface memory device and a M.2 interface connection seat insertedly provided thereof. The M.2 interface memory device comprises a M.2 interface card and a housing provided with at least one guide groove. The M.2 interface connection seat is disposed on a circuit board, and comprises two arms and a base comprising a M.2 interface slot. At least one arm is provided with a guide rail. An opening direction of the M.2 interface slot is horizontal to a surface of the circuit board. When the M.2 interface card is inserted into the M.2 interface slot in a horizontal direction, the M.2 interface memory device will be fixed within the M.2 interface connection seat by embedding between the guide groove and the guide rail. Thus, M.2 interface memory devices of a variety of specification lengths are able to be inserted into the M.2 interface connection seat.

Abstract: The invention provides a connector and a connection seat insertedly provided thereof, particularly to a connector and a connection seat conforming to M.2 interface standard specification. The M.2 interface connector comprises a M.2 interface card and a housing. The housing is used for cladding the body of the M.2 interface card. The housing is provided on at least one side surface thereof with at least one fixed member. The M.2 interface card is having a connection interface protruding from the bottom end of the housing. The M.2 interface connection seat is disposed on a circuit board, and it's top end is provided with a slot. The opening direction of the slot will be perpendicular to the surface of the circuit board. When the connection interface of the M.2 interface connector is inserting into the slot of the M.2 interface connection seat based on a vertical direction, the fixed member of the housing will be fixed on the body of the M.2 interface connection seat. Therefore, the M.

Abstract: The invention provides a fixed structure for an interface card. The interface card is fixed within an interface slot by the fixed structure. The interface slot is provided on a front side therefore with at least one protruding block. The fixed structure comprises a metal shell, which is assembled to a surface of the interface card, and comprises a pressing portion and an engaging portion. When the interface card is to be inserted into the interface card, the user presses the pressing portion of the metal shell so as to expand the engaging portion. When the interface card has been inserted into the interface card, the user will release the pressing portion of the metal shell so that the engaging portion can engage with the protruding block of the interface slot. Therefore, the interface card is steady fixed within the interface slot by means of the fixed structure.
