[0037] As Figure 1 shown, an ultrasonic device includes an ultrasonic main unit 1, a fuselage 2, and a support arm 3. The fuselage 2 includes a base 22 supported on the ground and a column 21 fixed above the base 22. The support arm 3 is connected to one end of the column 21 facing away from the base 22, and the ultrasonic main unit 1 is connected to the support arm 3. The ultrasonic main unit 1 can move up and down relative to the column 21 through the movement of the support arm 3, and the ultrasonic main unit 1 can also perform a pitching motion relative to the support arm 3. The touch-type ultrasonic main unit 1 can maintain the position and posture after movement.

[0038] As Figure 1 and Figure 2 shown, the ultrasonic main unit 100 includes a main unit housing, a display screen assembly 200, and a screen fixing member 300. The main unit housing includes a front shell 100 and a rear shell 700 connected to each other. The front shell 100 is in a square shape and is adhesively fixed to the outer periphery of the display screen assembly 200 by an adhesive such as a dot hot melt adhesive or an adhesive tape. The screen fixing member 300 is located in the cavity enclosed by the front shell 100 and the rear shell 700 and is fixed to the front shell 100. Various electronic components such as the ultrasonic main board inside the main unit housing are directly or indirectly installed on the screen fixing member 300. The display screen assembly 200 is embedded and installed on the front shell 100 from the front side of the front shell 100, and the screen fixing member 300 is located on the back side of the display screen assembly 200. Among them, the front side of the front shell 100 is the side facing the user end when the front shell 100 is in use, and the back side of the display screen assembly 200 is the side facing away from the display screen of the display screen assembly 200. The display screen assembly 200 is connected to the screen fixing member 300 through an intermediate connector, and the connection method between the intermediate connector and the screen fixing member 300 is a non-rigid connection.

[0039] As Figure 3 shown, the display screen assembly 200 includes a glass cover plate 210 and a display screen 220 stacked from the outside to the inside. The display screen 220 has a touch function. The area of the glass cover plate 210 is larger than the area of the display screen 220, and the four sides of the glass cover plate 210 extend outward a small part relative to the display screen 220. Combining Figure 5 , a step groove 131 is provided on the front side of the front shell 100, and the outer peripheral edge of the glass cover plate 210 of the display screen assembly 200 is adhesively fixed to the groove wall of the step groove 131.

[0040] For such an ultrasonic device, in addition to being adhesively connected to the front shell 100, the display screen assembly 200 is also additionally connected to a screen fixing member 300 fixed inside the front shell 100 through an intermediate connecting member. The intermediate connecting member and the screen fixing member 300 form a secondary anti-detachment protection structure for the display screen assembly 200, which is beneficial to preventing the display screen assembly 200 from detaching from the front shell 100 and improving the installation reliability of the display screen assembly 200.

[0041] In some embodiments, the intermediate connecting member is a fixing plate fixedly connected to the side surface of the display screen assembly 200. The fixing plate is provided with a through hole, and the part of the fixing plate provided with the through hole extends out from the back surface of the display screen assembly 200. The through direction of the through hole is perpendicular to the thickness direction of the display screen assembly 200. The screen fixing member 300 is provided with a clamping structure that penetrates through the through hole along the extension direction of its own plane. After the clamping structure of the screen fixing member 300 extends into the through hole, it is subjected to the circumferential limiting effect of the circumferential wall of the through hole, and a non-rigid connection structure is formed between the screen fixing member 300 and the fixing plate, so that the screen fixing member 300 is not easily detached from the display screen assembly 200 in the vertical direction of the display screen assembly 200. This non-rigid connection structure has a relatively high deformation tolerance for the fixing plate and the screen fixing member 300, can better eliminate the stress caused by deformation of the screen fixing member 300 and the fixing plate, reduce the risk of damage to the fixing plate and the screen fixing member 300, and ensure the long-term stability and reliability of the connection between the display screen assembly 200 and the screen fixing member 300. In an alternative embodiment, the intermediate connecting member can also be a threaded post fixed to the back surface of the display screen assembly 200, and the screen fixing member 300 is directly fixed to the threaded post on the back surface of the display screen assembly 200 by screwing.

[0042] Such as Figure 3 and Figure 4As shown, the front shell 100 and the display screen assembly 200 are both rectangular. The front shell 100 and the display screen assembly 200 each include two opposite wide sides and two opposite long sides. The wide side of the display screen assembly 200 corresponds to the wide side of the front shell 100, and the long side of the display screen assembly 200 corresponds to the long side of the front shell 100. At both ends of each wide side of the display screen assembly 200, there are screen connection holes 230. The intermediate connector includes a first fixing plate 410 and a second fixing plate 420. The first fixing plate 410 and the second fixing plate 420 are both fixed in the screen connection holes 230 on the corresponding wide sides of the display screen assembly 200 through first locking members 500. The through hole on the first fixing plate 410 is the first through hole 412, and the through hole on the second fixing plate 420 is the second through hole 422. The screen fixing member 300 is a rectangular screen fixing plate, and the outer dimension of the screen fixing plate is the same as the outer dimension of the display screen assembly 200. The screen fixing plate includes two opposite wide sides and two opposite long sides. The wide side of the screen fixing plate corresponds to the wide side of the display screen assembly 200, and the long side of the screen fixing plate corresponds to the long side of the display screen assembly 200. The clamping structure includes a first clamping structure and a second clamping structure located at opposite ends of the screen fixing plate. The first clamping structure passes through the first through hole 412 on the first fixing plate 410, and the second clamping structure passes through the second through hole 422 on the second fixing plate 420. The screen fixing plate is in limit cooperation with the first fixing plate 410 and the second fixing plate 420 respectively through the first clamping structure and the second clamping structure on opposite sides to achieve a non-rigid connection method, which can improve the connection reliability between the display screen assembly 200 and the screen fixing plate. In an alternative embodiment, the screen fixing member 300 is not limited to a flat screen fixing plate, and the screen fixing member 300 can also be a frame structure with partial internal hollowing.

[0043] As Figure 4 and Figure 7 shown, the first clamping structure and the second clamping structure are sheet-like structures extending in the same direction from the screen fixing plate. Such a setting facilitates the assembly of the screen fixing plate. One end of the screen fixing plate is provided with an opening 310, and the through direction of the opening 310 is set along the thickness direction of the screen fixing plate. The first clamping structure is a first clamping piece 320 extending from the hole wall of the opening 310 into the hole, and the second clamping structure is a second clamping piece 330 protruding and extending outward from the side wall at the other end of the screen fixing plate. Combining Figure 8 , a first clamping portion 411 passing through the opening 310 is provided on the first fixing plate 410. The first through hole 412 is provided on the first clamping portion 411, and the first clamping piece 320 extends into the first through hole 412 of the first clamping portion 411. Combining Figure 9, a second clamping portion 421 is provided on the second fixing plate 420, a second through hole 422 is provided on the second clamping portion 421, and the second clamping piece 330 extends into the second through hole 422 of the second clamping portion 421. In this way, non-rigid connections are achieved between both ends of the screen fixing plate and the first fixing plate 410 and the second fixing plate 420.

[0044] As Figure 5 and Figure 6 shown, the side wall of the front shell 100 includes an outer side wall 110 and an inner side wall 120 located inside the outer side wall 110. The outer side wall 110 and the inner side wall 120 form a stepped groove 131 on the front side of the front shell 100, and the outer side wall 110 and the inner side wall 120 form a return groove on the back side of the front shell 100. The snap structures and threaded post structures for connecting the front shell 100 and the rear shell 700 are all located in the return groove.

[0045] As Figure 6 and Figure 7 shown, a snap structure for achieving snap-fitting between the front shell 100 and the screen fixing member 300 is provided. Among them, the snap structure includes a first snap 140, a second snap 150, and a third snap 160 provided on the front shell 100, and a first snap position 340, a second snap position 350, and a third snap position 360 provided on the outer periphery of the screen fixing member 300; the first snap 140 and the first snap position 340 are snap-fitted, the second snap 150 and the second snap position 350 are snap-fitted, and the third snap 160 and the third snap position 360 are snap-fitted. Combining Figure 10 and Figure 11 shown, the first snap 140 is integrally formed on a wide side wall of the inner side wall 120 of the front shell 100. The first snap 140 is integrally formed on the side of the inner side wall 120 facing the outer side wall 110. The first snap position 340 is an annular structure integrally formed on the screen fixing member 300, and the clamping head of the first snap 140 extends into the hole in the middle of the first snap position 340. The second snap 150 is integrally formed on a long side wall of the inner side wall 120 of the front shell 100. The clamping head of the second snap 150 is integrally formed on the side of the inner side wall 120 facing away from the outer side wall 110, and the clamping head of the second snap 150 is placed above the second snap position 350; the third snap 160 is integrally formed on another long side wall of the inner side wall 120 of the front shell 100. The clamping head of the third snap 160 is formed on the side of the inner side wall 120 facing away from the outer side wall 110, and the clamping head of the third snap 160 is placed above the third snap position 360. This snap structure between the front shell 100 and the screen fixing member 300 facilitates pre-tightening during the assembly of the two and the connection reliability after assembly.

[0046] As Figure 6 and Figure 7As shown in the figure, a locking structure is provided between the front shell 100 and the screen fixing member 300 to lock the two. Among them, the locking structure includes a first stud 170 and a second stud 180 disposed in a rectangular groove of the front shell 110, and a first assembly hole 370 and a second assembly hole 380 disposed on the screen fixing member 300. A second locking member 600 is inserted between the first stud 170 and the first assembly hole 370, and between the second stud 180 and the second assembly hole 380. Among them, the first stud 170 and the first buckle 140 are disposed on opposite wide side walls of the front shell 100, and the second stud 180 is disposed at an intermediate position on opposite long side walls of the front shell 100.

[0047] The assembly process of this ultrasonic device is as follows: respectively install the first fixing plate 410 and the second fixing plate 420 at the positions of four screen connection holes 230 provided at the end of the display screen assembly 200, and lock them with four screws respectively.
