A memory device including a memory array and a method of manufacturing a memory device are provided. The memory array includes memory cells disposed in an array having multiple rows and multiple columns and a source line. Each memory cell includes a substrate, a gate structure in the substrate, a source, and a drain. The source and the drain are disposed on two sides of the gate structure along a first direction. The memory array defines a source lead-out region that includes a source contact line extending along the first direction. The source contact line is connected to common sources distributed along the first direction. Each common source is connected to the sources in a same row along a second direction perpendicular to the first direction. The source line is disposed on the source contact line, extends along the second direction, and is connected to the source contact line.

An outdoor portable device (100a) includes: a device body; and a wheel assembly (200a, 300a), connected to the device body and configured to drive the device body to move; and an external attachment assembly (100c), mounted at an exterior of the device body and connected to the device body, wherein, the external attachment assembly is configured to hold at least one outdoor tool.

A software upgrade method, an apparatus (50), a device (60), and a storage medium (70) are provided. The software upgrade method is performed by an energy storage device to be upgraded. The method includes: determining (S11) a version type of the energy storage device to be upgraded; and based on the version type of the energy storage device to be upgraded, determining (S12) a target interaction mode of at least one chip in the energy storage device to be upgraded to use the target interaction mode to receive a software upgrade protocol sent by a preset device, wherein an interaction mode of the chip includes at least one of an internal channel interaction, an external channel interaction, and an internal-external channel interaction.

A relay delay turn-off circuit and a relay control method. The relay delay turn-off circuit includes a power control chip (1) outputting a first safety signal, a micro-control chip (2) outputting a second safety signal and a control group signal, a delay module (3), and a relay driving module (4). The delay module (3) receives the first safety signal, the second safety signal, and the control group signal, and outputs a first enable signal (EN1), a second enable signal (EN2), and a safety status signal. When the micro-control chip (2) resets, the first enable signal (EN1) delays a turn-off action of the relay driving module (4) until after a preset time, which is greater than a reset time. The power control chip (1) and the micro-control chip (2) output the first safety signal and the second safety signal according to their respective safety states.

The present application relates to a plug-in device and a high-voltage power distribution box. The plug-in device includes a male end assembly and a female end assembly. The female end assembly includes an outer bracket, an inner bracket, a first elastic-pressing part, and a second elastic-pressing part. The outer bracket and the inner bracket are able to slide along a preset axis and have a limit fit. The first elastic-pressing part is connected to the inner bracket, and an electrical plug-in groove is defined on an inner side of the first elastic-pressing part. In a case where the male end assembly is inserted into the electrical plug-in groove, the first elastic-pressing part is able to apply elastic forces in opposite directions to two ends of the male end assembly that are disposed opposite to each other along the preset axis, respectively. The second elastic-pressing part is disposed between the inner bracket and the outer bracket. One end of the second elastic-pressing part is connected to one of the inner bracket and the outer bracket, and another end of the second elastic-pressing part is able to apply elastic forces in opposite directions to two ends of another of the inner bracket and the outer bracket that are disposed opposite to each other along the preset axis, respectively. The plug-in device and the high-voltage power distribution box provided in the present application solve the problem that looseness and displacement of fixing members of a plug-in member may lead to plastic deformation of the male end or the female end of the plug-in member and contact failure of the plug-in member.
