[0043] In the description of this utility model, it should be noted that, unless otherwise expressly specified or limited, the terms "mounted," "connected," and "connected" should be understood in a broad sense. For example, they can refer to fixed connections, detachable connections, or integral connections; mechanical connections, electrical connections; direct connections, indirect connections through an intermediate medium, and internal communication between two components. Those skilled in the art will understand the specific meanings of the above terms in this utility model based on the specific circumstances.

[0044] like Figure 1 A touch-controlled ultrasound device is shown, comprising a touch-controlled ultrasound host 1, a body 2, a support arm 3, and a tablet holder 4. The body 2 comprises a base 22 supported on the ground, and a column 21 fixed above the base. The support arm 3 is connected above the column 21, and the touch-controlled ultrasound host 1 is connected to the support arm 3. The touch-controlled ultrasound host 1 can be raised and lowered relative to the column 21 by the movement of the support arm 3. The touch-controlled ultrasound host 1 can also be pitched relative to the support arm 3, and the touch-controlled ultrasound host 1 can maintain its position and posture after the movement. The tablet holder 4 is connected to the end of the support arm 3 away from the body 21.

[0045] like Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 and Figure 5As shown, the touch-controlled ultrasound host 1 includes a host housing, a touch screen assembly, a bracket assembly, and a fixing member. The host housing includes a front shell 11 and a rear shell 12, which are interconnected. The front shell 11 is square-shaped, and the touch screen assembly is fixed to the interior of the front shell 11 using adhesive such as hot melt adhesive or self-adhesive adhesive. The bracket assembly is disposed within the host housing and includes a main bracket 13, an ultrasound motherboard 16, and a shielding cover assembly 17. The main bracket 13 is fixedly connected to the front shell 11 and is located on the side of the touch screen assembly facing the rear shell 12. The ultrasound motherboard 16 is mounted on the side of the main bracket 13 facing away from the touch screen assembly. The shielding cover assembly 17 is connected to the main bracket 13 and covers the outer periphery of the ultrasound motherboard 16. The fixing member is fixed to the side of the shielding cover assembly 17 facing the rear shell 12. The tablet fixing base 4 is connected to the side of the rear shell 12 facing away from the front shell 11. The tablet fixing base 4 is provided with a first connecting member that passes through the rear shell 12 and is fixedly connected to the fixing member.

[0046] This touch-controlled ultrasonic host is configured by setting a bracket assembly fixedly connected to the front shell 11 in the host shell. The bracket assembly includes a main bracket 13, an ultrasonic mainboard 16 and a shielding cover assembly 17; the main bracket 13 is fixedly connected to the front shell 11, and a fixing piece is set on the side of the shielding cover assembly 17 facing the rear shell 12. The first connecting piece on the flat plate fixing seat 7 can be fixedly connected to the fixing piece inside the host shell after passing through the rear shell 12. Such an arrangement can realize the fixed connection between the support arm 3, the tablet fixing seat 4 and the shielding cover assembly 17. Since the shielding cover assembly 17 is directly fixed on the main bracket 13, and the main bracket 13 is fixed on the front shell 11, the fixed connection between the front shell 11 and the touch screen assembly thereon and the tablet fixing seat 4 is realized. After the touch screen assembly, the front shell 11 and the bracket assembly are fixedly connected to form a whole. This whole transfers gravity to the tablet fixing seat 4 through the connection between the fixing part and the first connecting part, reducing the bearing capacity requirements of the screws connected between the front shell 11 and the rear shell 12. Therefore, only a small number of screws are required between the front shell 11 and the rear shell 12 to realize the fixed connection between the two, reducing the number of screws required in the assembly process, reducing assembly labor hours, reducing production costs, and facilitating subsequent disassembly and maintenance. In addition, compared with the installation method in the prior art in which the flat plate fixing seat 4 is fixed to the rear shell 12 by screws, this connection method can reduce the bearing capacity requirements of the rear shell 12 while ensuring that the connection reliability meets the requirements, so that the main bracket 13 is the most core load-bearing component. Since the main bracket 13, the shielding cover assembly 17 and the fixing parts are all made of metal, while the front shell 11 and the rear shell 12 are made of plastic, relatively speaking, the main bracket 13, the shielding cover assembly 17 and the fixing parts have stronger bearing capacity. The platform fixing seat 4 is fixed to the shielding cover assembly 17 by screws and then fixedly connected to the main bracket 13, which can reduce the requirements for the structural strength and wall thickness of the rear shell 12, which is conducive to realizing the flat design of the touch-controlled ultrasonic host 1.

[0047] In some embodiments, as Figure 4 and Figure 5 As shown, the fixing member is a hook 18 fixed to the side of the shield cover assembly 17 facing the rear housing 12, and the first connecting member is a fastener provided on the tablet fixing base 4, which passes through the rear housing 12 and engages with the hook 18. In other alternative embodiments, the fixing member can also be a fixed socket fixed to the side of the shield cover assembly 17 facing the rear housing 12, the fixed socket having a jack, and the first connecting member is a plug provided on the tablet fixing base 4, which is plugged and fixed to the jack of the fixed socket.

[0048] like Figure 1 and Figure 2 As shown, a mounting slot 121 is provided in the middle of the side of the rear housing 12 facing away from the front housing 11. The tablet holder 4 is fixed in the mounting slot 121. Both the mounting slot 121 and the tablet holder 4 are square in shape. A pair of hook holes 122 are provided in the upper half of the bottom of the mounting slot 121. A pair of fasteners on the tablet holder 4 extend into the interior of the main housing through the corresponding hook holes 122. The bottom of the mounting slot 121 also has three through holes 123, two of which are located in the lower half of the mounting slot 121, and the other through hole 123 is located between the two hook holes 122. Preferably, the three through holes 123 are arranged in an equilateral triangle. The tablet holder 4 is fixedly connected to the rear housing 12 via a second connecting member that passes through the three through holes 123.

[0049] like Figure 2 and Figure 4 As shown, a pair of hooks 18 and three connecting posts 19 are fixed to the side of the shielding cover assembly 17 facing the rear housing 12. The pair of hooks 18 are positioned correspondingly to a pair of hook holes 122 on the rear housing 12. A pair of fasteners on the tablet holder 4 pass through the pair of hook holes 122 and then snap onto the pair of hooks 18. The three connecting posts 19 are positioned correspondingly to the three through-holes 123 on the rear housing 12. The connecting posts 19 are provided with connecting holes, and the tablet holder 4 is fixed to the connecting holes via screws passing through the tablet holder 4 and the rear housing 12. This ensures a secure connection between the shielding cover assembly 17, the rear housing 2, and the tablet holder 4.

[0050] like Figure 3 and Figure 6As shown, the touch screen assembly includes a touch screen 141 and a screen connection bracket connected to the outside of the touch screen 141. The main bracket 13 is located in the cavity enclosed by the front shell 11 and the rear shell 12 and is fixed to the front shell 11. Various electronic components such as the ultrasonic mainboard 16 inside the host shell are directly or indirectly mounted on the main bracket 13. The touch screen 141 is embedded in the front of the front shell 11, and the main bracket 13 is located on the back of the touch screen 141; wherein, the front of the front shell 11 is the side of the front shell 11 facing the user end when in use, and the back of the touch screen 141 is the side of the touch screen 141 facing away from the touch screen. A snap-fit ​​structure for realizing the interlocking of the two along the thickness direction of the touch screen 141 and a locking structure for realizing the locking of the two along the thickness direction of the touch screen 141 are also provided between the front shell 11 and the main bracket 13.

[0051] like Figure 2 、 Figure 3 and Figure 6 As shown, the front shell 11 and the touch screen 141 are both rectangular, and each includes two opposite wide sides and two opposite long sides; the wide sides of the touch screen 141 correspond to the wide sides of the front shell 11, and the long sides of the touch screen 141 correspond to the long sides of the front shell 11. The main bracket 13 is also rectangular, and the long sides of the main bracket 13 correspond to the long sides of the front shell 11, and the wide sides of the main bracket 13 correspond to the wide sides of the front shell 11. The screen connection bracket includes a first screen connection bracket 142 and a second screen connection bracket 143 respectively connected to the two opposite wide sides of the touch screen 141; screen connection holes 1411 are provided on the two opposite wide sides of the touch screen 141, and the first screen connection bracket 142 and the second screen connection bracket 143 are both fixed to the screen connection holes 1411 on the wide sides of the touch screen 141 by screen locking members 144. The screen locking members 144 are specifically screws.

[0052] like Figure 6 - Figure 18As shown, the first screen connection bracket 142 is provided with a first limiting hole 1421, and the second screen connection bracket 143 is provided with a second limiting hole 1431. The portion of the first screen connection bracket 142 provided with the first limiting hole 1421 and the portion of the second screen connection bracket 143 provided with the second limiting hole 1431 extend from the back of the touch screen 141. The penetration direction of the first limiting hole 1421 and the second limiting hole 1431 is perpendicular to the thickness direction of the touch screen 141. The two opposite wide sides of the main bracket 13 are respectively provided with a first limiting piece 131 and a second limiting piece 132. The first limiting piece 131 is inserted through the first limiting hole 1421, and the second limiting piece 132 is inserted through the second limiting hole 1431. After the first limiting piece 131 of the main bracket 13 extends into the first limiting hole 1421, it is circumferentially limited by the peripheral wall of the first limiting hole 1421. After the second limiting piece 132 of the main bracket 13 extends into the second limiting hole 1431, it is circumferentially limited by the peripheral wall of the second limiting hole 1431. The main bracket 13 and the touch screen 141 cooperate with each other in the thickness direction of the touch screen 141 through the limiting pieces and the limiting holes. This arrangement forms a non-rigid connection structure between the main bracket 13 and the first screen connecting bracket 142, and between the main bracket 13 and the second screen connecting bracket 143, making it difficult for the main bracket 13 to separate from the touch screen 141 along the thickness direction of the touch screen 141. This non-rigid connection structure has a high tolerance for deformation of the main bracket 13, can effectively eliminate stress caused by deformation of the main bracket 13, reduce the risk of damage to the main bracket 13, and ensure the long-term stability and reliability of the connection between the touch screen 141 and the main bracket 13.

[0053] like Figure 7 、 Figure 8 and Figure 16 As shown, the side wall of the front shell 11 includes an outer peripheral wall 111 and an inner peripheral wall 112 located inside the outer peripheral wall 111. The outer peripheral wall 111 and the inner peripheral wall 112 form a step groove on the front side of the front shell 11. The inner peripheral wall 112 is bonded to the periphery of the touch screen assembly. The outer peripheral wall 111 and the inner side wall form a groove 113 on the back side of the front shell 11.

[0054] like Figure 6 and Figure 7 As shown, the locking structure includes multiple locking members 15 connected between the front shell 11 and the main bracket 13 along the thickness direction of the touch screen 141. The two long sides and one wide side of the main bracket 13 are fixed to the corresponding side of the front shell 11 through the locking members 15. Specifically, the long side of the main bracket 13 is fixed to the long side of the front shell 11 by one screw, and the wide side of the main bracket 13 is fixed to the wide side of the front shell 11 by three screws; the locking members 15 are locking screws. Figure 12 and Figure 13As shown, the groove 113 of the front housing 11 is provided with a first stud 117, one first stud 117 is provided in the middle of the two long sides of the front housing 11, and three first studs 117 are provided on one wide side of the front housing 11. Each of the two long sides of the main bracket 13 is provided with an assembly hole 138, and each of the wide sides of the main bracket 13 is provided with three assembly holes 138. The assembly holes 138 and the first studs 117 are positioned correspondingly. The locking member 15 passes through the assembly holes 138 and is connected to the first studs 117 to achieve a fixed connection between the front housing 11 and the main bracket 13. Second studs 118 for connecting to the rear housing 12 are also provided at the four corners of the front housing 11.

[0055] like Figure 7 、 Figure 8 、 Figure 13 、 Figure 14 and Figure 16 As shown, the snap-fit ​​structure includes a plurality of first retaining buckles 114 disposed on both long sides of the inner peripheral wall 112. The buckle heads 1141 of the first retaining buckles 114 extend toward the side of the main bracket 13 facing away from the touch screen 141. The plurality of first retaining buckles 114 enclose a sliding cavity on one side of the front housing 11. When the main bracket 13 and the front housing 11 are not secured by the locking member 15, the main bracket 13 can slide horizontally within the sliding cavity.

[0056] like Figure 13 、 Figure 14 and Figure 15 As shown, the long side of the main bracket 13 is provided with a plurality of notches 133, and one side of the notch 133 is provided with a buckle 137. The main bracket 13 has a first position and a second position during the horizontal sliding process in the sliding cavity. When the main bracket 13 is in the first position, see Figure 6 、 Figure 8 and Figure 10 The first limiting buckle 114 is located on the buckle position 137. The buckle head 1141 of the first limiting buckle 114 is staggered with the notch 133 and blocks the main bracket 13. The first limiting piece 131 extends into the first limiting hole 1421, and the second limiting piece 132 extends into the second limiting hole 1431. Multiple first limiting buckles 114 can limit and fix the main bracket 13, improve the connection reliability between the main bracket 13 and the touch screen 141, and reduce the number of screws used during assembly. When the main bracket 13 is in the second position, see Figure 7 、 Figure 9 and Figure 11 , the first limiting buckle 114 leaves the buckle position 137, the buckle head 1141 of the first limiting buckle 114 is set corresponding to the position of the notch 133, the first limiting piece 131 does not extend into the first limiting hole 1421, and the second limiting piece 132 does not extend into the second limiting hole 1431; at this time, the main bracket 13 can be removed from the front shell 11 for easy disassembly and assembly.

[0057] like Figure 15 As shown, the main bracket 13 is provided with an opening 136 extending along its thickness, and a first limiting piece 131 and a second limiting piece 132 extend in the same direction from the main bracket 13. The first limiting piece 131 extends from the hole wall into the hole 136, and the second limiting piece 132 protrudes outward from the side wall of the other end of the main bracket 13.

[0058] like Figure 11 、 Figure 10 and Figure 16 As shown, the snap-fit ​​structure also includes a plurality of second retaining buckles 115 disposed on a short side of the inner peripheral wall 112. The second retaining buckles 115 are protrusions extending from the inner peripheral wall 112 toward the groove 113. A bent portion 134 extending into the groove 113 is provided on one wide side of the main bracket 13. The bent portion 134 is provided with a retaining hole 1341, and the second retaining buckles 115 engage with the retaining hole 1341. The retaining hole 1341 on the bent portion 134 engages with the second retaining buckles 115 on the front shell 11, further improving the connection reliability between the main bracket 13 and the front shell 11.
