A control apparatus for a switch. The control apparatus is fixed on a housing (100). The control apparatus comprises a button (300) matching a switch (410) in the housing (100). The control apparatus also comprises a partition (350) provided between the button (300) and the switch (410). The housing (100) is provided with a switch opening (121) corresponding to the switch (410). The partition (350) fits a sidewall surrounding the switch opening (121) and seals the switch opening (121). The button (300) is provided with a trigger point (310) arranged at the position of the switch opening (121). The trigger point (310) is smaller than the switch opening (121). A pressing force is applied on the button (300); the trigger point (310) is abutted against the partition (350) to distend the partition (350) to trigger the switch (410). When the force transmitted by the button (300) is applied on the partition (350), a part of the force acts on the sidewall surrounding the switch opening (121), while a part of the force is used in triggering the switch (410). As such, if the pressing force is too weak, then the partition cannot be distended and thus the switch cannot be triggered, thus preventing the switch from being triggered due to the button being touched inadvertently and preventing misuse.
A: A wake-up lamp, comprising a housing (100), a light-transmitting member (200) and a display control module (300), wherein the housing (100) has a first light-transmitting region; the light-transmitting member (200) and the display control module (300) are both arranged in the housing (100); the light-transmitting member (200) is located between the display control module (300) and the first light-transmitting region; the surface of the light-transmitting member (200) facing the display control module (300) or the surface of the light-transmitting member (200) facing the first light-transmitting region is provided with a key pattern (210); the surface of the display control module (300) opposite the light-transmitting member (200) is provided with a first light-emitting member (310) and a touch switch (320); the touch switch (320) is electrically connected to the first light-emitting member (310); and when the touch switch (320) is triggered, light emitted by the first light-emitting member (310) irradiates the light-transmitting member (200), so as to project the key pattern (210) onto the first light-transmitting region. This solution can solve the problem that an existing wake-up lamp has a poor appearance due to dark spots exist in a housing of the wake-up lamp.
B: Disclosed in the present application is a mouse. The mouse comprises a bottom plate, a housing and keys arranged on the housing, wherein the keys comprise a left key and a right key, and a roller is arranged between the left key and the right key; a trigger switch is arranged on the bottom plate in a position corresponding to the keys; a first clamping hook is arranged on bottom surfaces of the keys; a base is arranged on the bottom plate, a regulating column is arranged above the base, and a boss is arranged on a side surface of a top end of the regulating column; a spring is sleeved on the regulating column, and the top end of the regulating column passes through a through hole on the housing that is used for accommodating the regulating column; and the boss at the top of the regulating column is engaged with the first clamping hook on the bottom surfaces of the keys, and the spring is compressed between the housing and a bottom end of regulating column such that the rebound height of the keys is limited. The mouse of the present application is convenient for a user to control the hand feeling of the keys of the mouse.
C: Disclosed are an accidental-shutdown-proof switch control apparatus and method for a robot-assisted surgical device. The control apparatus comprises: a startup/shutdown key, wherein the startup/shutdown key is used for triggering a startup/shutdown action; a system power module, wherein the system power module is used for connecting to a power supply to supply power to power utilization modules of a robot-assisted surgical device; a startup/shutdown control module, wherein the startup/shutdown control module is used for detecting a shutdown action of the startup/shutdown key and acquiring a shutdown intention by means of manual interaction; and a startup/shutdown hardware circuit, wherein the startup/shutdown hardware circuit is used for detecting a startup action and controlling the system power module to start supplying power, and the startup/shutdown hardware circuit controls the system power module to stop supplying power when simultaneously detecting two signals, i.e. a shutdown action and a shutdown control signal sent by the startup/shutdown control module. The control apparatus can reduce, despite the cost barely being increased, the probability of a system software and hardware fault or a manual misoperation possibly causing an accidental shutdown, thereby further improving the reliability of the operation of a device.
D: A key device (200), comprising a touch component (3) and a switch (1) provided underneath the touch component (3), wherein the touch component (3) is used for outputting a touch signal according to a touch action, and when the touch component (3) is pressed, the subjected pressure can be conducted to the switch (1) and a pressing signal is output. Also related is a terminal (100) applying the key device (200) and a key device (200) manipulation and control method. In the key device (200) and the terminal (100), the function of a mechanical key can be realized by a switch (1), so as to avoid an erroneous touch, and the touch component can realize a relatively flexible touch control and simultaneously have two control functions, namely, a touch function and a mechanical key function.
