Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of medical equipment, in particular to a keyboard and an ultrasonic diagnostic device. BACKGROUND

[0002] The ultrasonic diagnostic device is a technology for non-invasively measuring the inside of a living body, which transmits an ultrasonic wave signal to the inside of the living body, receives a reflected ultrasonic wave signal, and obtains an ultrasonic image by processing the reflected ultrasonic wave signal to diagnose the living body.

[0003] The existing ultrasonic diagnostic device generally comprises a main machine, a control platform arranged on the main machine, and a keyboard assembly arranged on the control platform. The keyboard assembly comprises a trackball, a plurality of first keys arranged around the trackball, and a plurality of second keys scattered outside the trackball. The keyboard assembly further comprises a circuit board and a panel connected with each other. The circuit board is located below the panel. The circuit board and the panel are both provided with mounting holes. The mounting holes on the circuit board and the panel are communicated. An installation assembly is connected below the circuit board. The trackball is rotatably arranged in the installation assembly and protrudes above the installation hole at the top end of the trackball. Each first key and each second key comprises a self-resetting silica gel key and a first key cap connected to the silica gel key. The panel is provided with a plurality of through holes for the silica gel keys to pass through. A silica gel pad is arranged between the circuit board and the panel. The silica gel keys of the first keys and the second keys protrude from the silica gel pad to the direction away from the circuit board. The circuit board is provided with a first terminal corresponding to the position of the silica gel key. The silica gel key is provided with a second terminal corresponding to the first terminal at the position on the circuit board. The operator presses the first key cap to drive the silica gel key to move to the direction of the circuit board to make the second terminal on the silica gel key contact with the first terminal on the corresponding circuit board, thereby realizing the input of information.

[0004] The above keyboard assembly arranges the first keys around the trackball to effectively shorten the distance of the operator when switching the first keys and the trackball. Such arrangement makes the first keys span a larger area. In addition, the silica gel key has a soft material. If the pressing direction of the operator when pressing the first key cap is not vertically downward, the silica gel key and the first key cap may be offset together, the second terminal is offset relative to the first terminal, and the second terminal cannot be connected with the first terminal, causing the key to fail, which seriously affects the stability of the keyboard assembly.

[0035] The clamping block 42 is slidably clamped in the clamping groove 41, which ensures the sliding of the clamping block 42 along the sliding direction of the first reset key 21 and limits the movement of the clamping block 42 in the horizontal direction through the clamping groove 41, thereby reducing the possibility that the pressing force direction of an operator pressing the first key cap 22 deviates in the horizontal direction and causes the first key cap 22 and the first reset key 21 to deviate, reducing the possibility that the second terminal 211 deviates relative to the first terminal 51, thereby reducing the possibility that the first key 2 fails and improving the stability of the keyboard operation. Even if the first keys 2 arranged around the trackball 1 span a larger area and the silicone key material is relatively soft, the pressing direction of the operator pressing the first key cap 22 is not vertically downward under the action of the clamping assembly 4, and the silicone key and the first key cap 22 will not deviate together.

The first reset key 21 and the reset pad 6 are connected by a slope to achieve automatic reset of the first reset key 21.

[0038] In some embodiments, referring to Figures 1-9 , the size of the mounting hole 8 on the panel 7 is larger than the size of the mounting hole 8 on the mounting frame 3, the reset pad 6, and the circuit board 5, and the mounting hole 8 on the panel 7 is used to expose the part of the mounting frame 3 for mounting the first keycap 22, thereby facilitating the installation and removal of the first keycap 22.

[0039] In some embodiments, referring to Figures 1-9 , a plurality of clamping assemblies 4 are arranged between the mounting frame 3 and each first keycap 22, and the plurality of clamping assemblies 4 of each first keycap 22 are evenly distributed between the first keycap 22 and the mounting frame 3.

On the other hand, the abutment of the ends of the rib 221 against the side wall of the receiving groove 212 further reduces the possibility of deviation of the first reset key 21 relative to the corresponding first keycap 22 when the first key 2 is pressed, and reduces the possibility of deviation of the second terminal 211 on the first reset key 21 relative to the first terminal 51 on the circuit board 5.
