Description

Technical Field

[0002] An ultrasonic device generally includes a main unit, a display device, a control panel, and a support arm for supporting the control panel. The control panel is installed on the main unit, which makes the ultrasonic device have a certain height, especially for desktop ultrasonic devices, which are larger in size. During the transportation of the bare machine (for example, when an agent transports the machine over a short distance), it is usually necessary to place the ultrasonic device in the trunk of a car (since the quantity is small, usually an SUV-like vehicle is used for transportation). Due to the limitation of the height of the trunk of common vehicles, it is necessary to reduce the height of the whole machine to a very low level. However, it is difficult to improve the compactness in the structural design of the ultrasonic device. Therefore, how to store the ultrasonic device at a sufficiently low height has become an urgent problem to be solved currently. Summary of the Invention

[0039] In one embodiment, an ultrasonic device is provided. Please refer to Figure 1 and 2, the ultrasonic device includes a main unit 4, a display device 13 with a display screen, a control panel 2, and a support arm 35 for supporting the control panel. The main unit 4 can be provided with casters 5 to facilitate the movement of the ultrasonic device. The display device 13 is used to display information on the processing process, the results of the completed processing, or other information. The ultrasonic device further includes a support arm 15 for supporting the display device 13. Generally, buttons, knobs, etc. are provided on the control panel 2, and the user can operate the ultrasonic diagnostic instrument through the control panel 2.

[0040] The support arm 35 includes a first end 31 of the support arm and a second end 32 of the support arm. The first end 31 of the support arm is rotatably connected to the main unit 4, and the second end 32 of the support arm is rotatably connected to the control panel 2. Among them, the control panel 2 includes an operation area 21 and a connection area. The connection area is connected to the operation area 21, and the height of the connection area is higher than that of the operation area 21. The second end 32 of the support arm is rotatably connected to the connection area. The rotatable connection between the first end 31 of the support arm and the main unit 4 and the rotatable connection between the second end 32 of the support arm and the control panel 2 are not limited to any form of rotatable connection, such as shaft-hole connection, bearing connection, etc. Generally, buttons, knobs, etc. are provided on the operation area, and the user can operate the ultrasonic diagnostic instrument through the operation area. The connection area is mainly used to connect the entire control panel 2 to the support arm 35. Compared with the prior art solution where the height of the connection area is lower than that of the operation area or the connection area is at the bottom of the operation area, in this technical solution, that is, the height of the connection area is higher than that of the operation area 21, the height of the control panel can be reduced, thereby reducing the height of the ultrasonic device and facilitating its storage and transportation.

[0041] In one embodiment, on the basis of the above embodiment, please refer to Figure 2, the support arm 35 can rotate to enable the ultrasonic device to enter the storage state, and in the storage state, the height of the first end 31 of the support arm is greater than the height of the second end 32 of the support arm. The storage state refers to the state when both the support arm 35 and the control panel 2 are lowered to the lowest height. The first end 31 of the support arm is rotatably connected to the host 4, and can be rotated up and down, or can be rotated up and down and horizontally at the same time. The control panel 2 is rotatably connected to the second end 32 of the support arm, and can be rotated up and down, or can be rotated up and down and horizontally at the same time. By rotating the support arm 35 up and down, both the support arm 35 and the control panel 2 can be lowered to the lowest height. In the storage state, the height of the first end 31 of the support arm is greater than the height of the second end 32 of the support arm. The support arm is inclined, and the control panel connected to the second end of the support arm is further lowered in height, thereby further reducing the height of the ultrasonic device, facilitating its storage and transportation.

[0042] In one embodiment, based on the above embodiment, please refer to Figure 2 , the support arm can rotate to enable the ultrasonic device to enter the storage state, and in the storage state, the operation area of the control panel is in the same plane as the support arm.
