[0042] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model.

[0043] The following disclosure provides numerous different embodiments or examples for implementing various structures of the present invention. To simplify the disclosure, specific examples of components and arrangements are described below. These are merely examples and are not intended to limit the scope of the invention. Furthermore, reference numerals and / or letters may be repeated in different examples. Such repetition is for simplification and clarity and does not in itself indicate a relationship between the various embodiments and / or arrangements discussed. In addition, examples of various specific processes and materials are provided in this invention; however, those skilled in the art will recognize the applicability of other processes and / or the use of other materials.

[0044] The ultrasonic device 100 according to an embodiment of the present invention will now be described with reference to the accompanying drawings.

[0045] Reference Figure 1 and Figure 2 The ultrasonic device 100 includes a display device 10 and a support device 20, combined with Figure 3 The display device 10 includes a housing assembly 1 and a screen assembly 2. The housing assembly 1 includes a rear housing 11 and a front frame 12. The screen assembly 2 is located between the rear housing 11 and the front frame 12. The screen assembly 2 includes a screen body 21 and a connecting structure 22 that supports the screen body 21. The support device 20 is used to support the display device 10. The display device 10 is assembled and connected to the support device 20 through the connecting structure 22.

[0046] Among them, the ultrasound device 100 is a medical device that uses the physical properties of ultrasound to diagnose or treat diseases. It emits ultrasound waves into the human body and receives the reflected ultrasound signals. After processing, it forms an image of the internal structure of the human body to assist doctors in diagnosing diseases. The display device 10 is a component in the ultrasound device 100 used to display ultrasound images and related information. It is an important interface for operators to interact with the ultrasound device 100.

[0047] The screen 21 of the display device 10 can be a display screen or a touch screen.

[0048] The support device 20 can be a floating support device or a fixed support device. For example, the floating support device can be in the form of a robotic arm, and the fixed support device can be in the form of a bracket or a hanger.

[0049] In related technologies, ultrasonic equipment display devices typically consist of a display screen and a housing. The housing includes a front shell and a rear shell. After the display screen is fixed to the front or rear shell using screws to form an assembly, the housing is then installed and fixed to a floating arm or bracket. However, when the display screen is locked to the housing with screws, and the housing is then installed and fixed to the floating arm or bracket, forces generated by bumps and vibrations act directly on the housing. These forces can easily cause the housing itself or connecting studs to break, leading to housing damage. This results in instability in the housing's support for the display screen, affecting the structural reliability of the display device.

[0050] In the technical solution of this application, the display device 10 is assembled and connected to the support device 20 through the adapter structure 22 that supports the screen body 21. Thus, the weight of the screen assembly 2 is directly supported on the support device 20. The shell assembly 1 does not need to be damaged by factors such as bumps or vibrations due to supporting the screen assembly 2 and being connected to the support device 20. This effectively protects the shell assembly 1 and allows the shell assembly 1 and the screen assembly 2 to maintain a good fit, improving the structural stability of the display device 10 and the connection reliability between the display device 10 and the support device 20, thereby enabling the display device 10 to work reliably and stably.

[0051] Moreover, since the shell assembly 1 does not need to support the screen assembly 2, the shell assembly 1 can be designed to be thinner and lighter. There is also no need for a large connection and locking force between the shell assembly 1 and the screen assembly 2, which avoids excessive locking force acting directly on the screen body 21, causing phenomena such as light leakage or water ripples on the screen body 21.

[0052] Furthermore, the screen assembly 2 is located between the rear shell 11 and the front frame 12. The rear shell 11 and the front frame 12 provide a protective and fixed frame for the screen assembly 2, and make the connection between the shell assembly 1 and the screen assembly 2 more reliable and stable. This further enhances the structural stability of the display device 10 and reduces the problems such as displacement or damage of the screen assembly 2 relative to the shell assembly 1 caused by external force collisions or vibrations during the use of the display device 10.

[0053] Reference Figure 4 In some embodiments, the front frame 12 is connected to the rear shell 11, and one or both of the front frame 12 and the rear shell 11 are connected to the screen assembly 2. That is, the screen assembly 2 can be connected to the rear shell 11 alone, the screen assembly 2 can be connected to the front frame 12 alone, or the screen assembly 2 can be connected to both the rear shell 11 and the front frame 12 simultaneously.

[0054] The connection method between the front frame 12 and the rear shell 11, and between one or both of the front frame 12 and the rear shell 11 and the screen assembly 2, is not limited. For example, it can be a snap-fit ​​connection, a screw connection, an adhesive connection, etc. Furthermore, the distribution of the connection points is not limited. For example, the connection points can be evenly distributed around the screen assembly 2, or they can be non-uniformly distributed according to the weight distribution and stress of the screen assembly 2. The number of connection points can be appropriately increased or decreased according to the size and weight of the screen assembly 2 to ensure sufficient fixing force.

[0055] In the above technical solution, the front frame 12 and the rear shell 11 are connected to form a relatively stable shell structure, which enables the shell assembly 1 and the screen assembly 2 to be reliably connected. The shell assembly 1 can provide a reliable protective frame for the screen assembly 2, reduce the direct impact of external forces on the screen assembly 2, reduce the risk of damage to the screen assembly 2, and thus extend the service life of the display device 10 of the ultrasonic equipment 100.

[0056] Reference Figure 5 In some embodiments, the rear shell 11 defines a receiving cavity 111 that opens toward the front frame 12, the screen assembly 2 is received in the receiving cavity 111, and the rear shell 11 is engaged with the adapter structure 22 and / or connected by a first fastener M1. That is, the rear shell 11 and the adapter structure 22 can be connected by engagement alone or by the first fastener M1, or they can be connected by both engagement and the first fastener M1.

[0057] For example, such as Figure 5 As shown, the back cover 11 and the adapter structure 22 can be engaged by snap-fitting on the upper edge, left edge and right edge of the back cover 11, and the lower edge of the back cover 11 is connected to the adapter structure 22 by the first fastener M1. Of course, all four sides can be engaged by snap-fitting or connected by the first fastener M1, or each side can be engaged by snap-fitting and connected by the first fastener M1.

[0058] In the above technical solution, the rear shell 11 defines a receiving cavity 111 that opens towards the front frame 12 and houses the screen assembly 2 therein. The screen assembly 2 includes a screen body 21 and a connecting structure 22. The receiving cavity 111 provides space for the screen body 21 and the connecting structure 22, thereby making the shell assembly 1 and the screen assembly 2 compactly arranged. In addition, the rear shell 11 can also protect the screen assembly 2. When the display device 10 is subjected to collision or vibration, the rear shell 11 can reduce the direct external force acting on the screen assembly 2 and improve the impact resistance of the screen assembly 2.

[0059] In the above technical solution, the rear shell 11 and the adapter structure 22 are connected by a snap-fit ​​and / or by a first fastener M1, which enhances the connection stability between the rear shell 11 and the screen assembly 2. The snap-fit ​​connection between the rear shell 11 and the adapter structure 22 offers the advantages of convenient and quick installation and disassembly, improving assembly efficiency. The connection between the rear shell 11 and the adapter structure 22 by the first fastener M1 (such as screws or bolts) ensures a firm fixation between the rear shell 11 and the adapter structure 22, enhancing the connection reliability between the rear shell 11 and the screen assembly 2.

[0060] Reference Figure 4 In some embodiments, the edge of the front frame 12 and the edge of the rear shell 11 are engaged by a snap-fit ​​structure M2 and / or connected by a second fastener. That is, the edge of the front frame 12 and the edge of the rear shell 11 can be engaged by the snap-fit ​​structure M2 alone or connected by the second fastener, or they can be engaged by both the snap-fit ​​structure M2 and the second fastener.

[0061] In the above technical solution, when the edge of the front frame 12 and the edge of the rear shell 11 are engaged by the snap-fit ​​structure M2, the snap-fit ​​structure M2 is not limited. For example, it can be a snap-fit ​​of one edge of the front frame 12 and the snap-fit ​​groove of the other edge that interlocks with each other, making the installation process simpler and faster, improving production efficiency. When subjected to a certain degree of horizontal external force, the mechanical interlock of the snap-fit ​​and the snap-fit ​​groove can prevent the front frame 12 and the rear shell 11 from separating, providing basic structural support for the display device 10. When the edge of the front frame 12 and the edge of the rear shell 11 are connected by the second fastener (such as screws, bolts, etc.), a strong connection force can be provided, which can resist vertical external force and large vibration and impact, improving the reliability of the connection and effectively protecting the internal electronic components and screen assembly 2. When the snap-fit ​​and the second fastener are used in combination, the snap-fit ​​can first perform preliminary positioning and fixation of the front frame 12 and the rear shell 11, which facilitates the subsequent precise connection and reinforcement using the second fastener, thereby making the connection more stable and improving the reliability of the connection between the edge of the front frame 12 and the rear shell 11.

[0062] Furthermore, since the rear shell 11 defines a receiving cavity 111 that opens towards the front frame 12, the screen assembly 2 is housed in the receiving cavity 111. The rear shell 11 is engaged with the adapter structure 22 and / or connected by a first fastener M1; the edge of the front frame 12 is engaged with the edge of the rear shell 11 by a snap-fit ​​structure M2 and / or connected by a second fastener. Therefore, no locking force is required between the front frame 12 and the screen assembly 2, or a large locking force is required, avoiding excessive locking force acting directly on the screen body 21, which could cause light leakage or water ripples on the screen body 21.

[0063] Reference Figure 6In some embodiments, a buffer pad 3 is sandwiched between the front frame 12 and the screen 21. The material of the buffer pad 3 is not limited; for example, it can be an EVA foam pad, a rubber pad, or a silicone pad. Thus, the buffer pad 3 sandwiched between the front frame 12 and the screen 21 can play a shock-absorbing and cushioning role. When the front frame 12 is subjected to external force (such as an impact), the buffer pad 3 will undergo elastic deformation, absorbing and dispersing some of the impact energy, thereby reducing the impact force transmitted to the screen 21, reducing the risk of the screen 21 breaking or being damaged due to strong impact, and extending the service life of the screen 21.

[0064] Furthermore, the buffer pad 3 typically possesses a certain degree of flexibility and sealing properties, thereby filling the minute gap between the front frame 12 and the screen body 21 and reducing the entry of dust, moisture, and other impurities into the screen body 21 through this gap. Dust entering the screen body 21 may adhere to the surface of the display screen or internal components, affecting display quality and the normal operation of components; moisture, on the other hand, can cause serious problems such as short circuits and component corrosion within the screen body 21. The sealing effect of the buffer pad 3 improves the dust and moisture resistance of the screen body 21, thereby enhancing the reliability of the display device 10.

[0065] Reference Figure 3 In some embodiments, an opening region 112 is formed on the rear shell 11, and the transition structure 22 and the support device 20 are assembled and connected through the opening region 112. By providing the opening region 112 on the rear shell 11, the transition structure 22 can be exposed through the opening region 112 to form a connection with the support device 20. For example, the transition structure 22 can extend out of the rear shell 11, or the support device 20 can extend into the rear shell 11, thereby facilitating the assembly and connection of the transition structure 22 and the support device 20, reducing assembly difficulty, and improving assembly efficiency.

[0066] In the embodiments of this application, the shape of the opening region 112 is not limited, and can be circular, square, rectangular, or irregular, etc. Different shapes are suitable for different assembly requirements and match different shapes of the transition structure 22 and the support device 20. The size of the opening region 112 is not limited, but it should be able to allow the transition structure 22 and the support device 20 to pass through smoothly and be assembled and connected.

[0067] Reference Figure 7 In some embodiments, the assembly connection between the adapter structure 22 and the support device 20 includes one or more of the following: plug-in engagement, snap-fit ​​engagement, and connection via a third fastener M3. Plug-in and snap-fit ​​engagements do not require complex tools or procedures, allowing operators to quickly assemble the adapter structure 22 and support device 20, thus shortening assembly time. The connection between the adapter structure 22 and support device 20 via the third fastener M3 provides a more robust connection and improves connection reliability.

[0068] For example, such as Figure 7 As shown, the adapter structure 22 includes a mounting part 222 and a mating part 223. A slot 2231 is formed between the mating part 223 and the mounting part 222. The upper part of the mounting end 201 of the support device 20 is provided with a plug that matches the slot 2231. The plug is inserted into the slot 2231. Mounting holes are provided on both sides of the mounting end 201. A third fastener M3 passes through the mounting holes to connect with the adapter structure 22.

[0069] Reference Figure 6 , Figure 7 and Figure 8 In some embodiments, the adapter structure 22 includes a carrier 221, a mounting member 222, and a mating member 223. The carrier 221 is located between the screen body 21 and the rear shell 11 and is connected to the screen body 21, with the screen body 21 supported by the carrier 221. The mounting member 222 is located between the carrier 221 and the rear shell 11 and is connected to the carrier 221. The support device 20 is connected to the mounting member 222. The mating member 223 is located between the mounting member 222 and the rear shell 11, and a slot 2231 is formed between the mating member 223 and the mounting member 222. The support device 20 is inserted into the slot 2231.

[0070] In the above technical solution, the transition structure 22 includes multiple components such as a bearing member 221, a mounting member 222, and a mating member 223, thereby meeting various connection requirements of the transition structure 22. Specifically, the bearing member 221 is located between the screen body 21 and the rear shell 11 and is connected to the screen body 21, satisfying the connection requirements between the screen body 21 and the transition structure 22. It provides a stable connection and support foundation for the screen body 21. Through the structural design of the bearing member 221, the weight and external forces borne by the screen body 21 are effectively distributed, preventing deformation or damage to the screen body 21 due to uneven stress. The mounting member 222 connects to the bearing member 221, further reinforcing the connection relationship between the various components of the transition structure 22. The support device 20 is connected to the mounting member 222, and the mating member 223 forms a slot 2231 with the mounting member 222, supporting... The support device 20 is plugged into the slot 2231, which meets the connection requirements between the adapter structure 22 and the support device 20. The plug-in structure can provide a reliable connection force, restrict the relative movement between the support device 20 and the adapter structure 22, and improve the connection reliability between the support device 20 and the adapter structure 22. The plug-in connection method for connecting the support device 20 and the adapter structure 22 is simple and quick to install. The support device 20 can be quickly inserted into the slot 2231 to complete the connection. When maintenance or replacement of parts is required, the support device 20 can also be easily pulled out of the slot 2231, which improves the maintainability and maintenance efficiency of the equipment.

[0071] In addition, the support member 221, the mounting member 222 and the mating member 223 are arranged sequentially between the screen body 21 and the rear shell 11, making full use of the internal space of the display device 10, so that the components can be arranged compactly together, reducing the overall volume of the display device 10.

[0072] Reference Figure 7 , Figure 8 and Figure 9 In some embodiments, the mounting component 222 is constructed as a shielding cover 222a, which includes a cover body 222a1 and a connecting part 222a2. A circuit board 4 is provided between the cover body 222a1 and the carrier 221, and the connecting part 222a2 is assembled and connected to the support device 20. The circuit board 4 can be electrically connected to the shielding body 21 by wiring or other means.

[0073] In the above technical solution, the mounting component 222 is constructed as a shielding cover 222a, meaning that the mounting component 222 also functions as a shielding cover 222a, thereby reducing the number of components in the display device 10. A circuit board 4 is disposed between the cover portion 222a1 of the shielding cover 222a and the carrier component 221. The cover portion 222a1 of the shielding cover 222a can shield the circuit board 4 from external electromagnetic interference. Specifically, external electromagnetic interference coupled to the circuit board 4 may affect the normal transmission and processing of signals in the circuit, leading to display errors in the display device 10. The cover portion 222a1 of the shielding cover 222a can block the entry of these external electromagnetic waves, ensuring the stable operation of the electronic components on the circuit board 4. Furthermore, the shielding cover 222a provides a certain degree of protection for the circuit board 4, preventing dust, moisture, etc., from entering the space where the circuit board 4 is located, thereby improving the reliability of the display device 10.

[0074] In the above technical solution, the shielding cover 222a includes a connecting part 222a2, and the connecting part 222a2 is assembled and connected to the support device 20. Thus, the shielding cover 222a also has the function of being assembled and connected to the support device 20, which reduces the number of parts of the display device 10 and improves the space utilization and the overall structure.

[0075] Reference Figure 9 and Figure 10 In some embodiments, the adapter structure 22 includes a support member 221 and a shielding cover 222a. The support member 221 is disposed between the screen body 21 and the rear shell 11 and is connected to the screen body 21, with the screen body 21 supported by the support member 221. The shielding cover 222a is disposed between the support member 221 and the rear shell 11, and a circuit board 4 is provided between the shielding cover 222a and the support member 221. The circuit board 4 is electrically connected to the screen body 21. In this embodiment, the connection method between the adapter structure 22 and the support device 20 is not limited; that is, in this embodiment, the shielding cover 222a may have a connecting part 222a2 or may not have a connecting part 222a2.

[0076] In the above technical solution, the carrier 221 is disposed between the screen body 21 and the rear shell 11 and connected to the screen body 21, satisfying the connection requirements between the screen body 21 and the adapter structure 22. Through the structural design of the carrier 221, it provides a stable connection and support foundation for the screen body 21, effectively distributing the weight and external forces borne by the screen body 21 and preventing deformation or damage to the screen body 21 due to uneven stress. A circuit board 4 is disposed between the shielding cover 222a and the carrier 221. The circuit board 4 is electrically connected to the screen body 21, and the shielding cover 222a can protect the electrical connection between the circuit board 4 and the screen body 21 to a certain extent. Specifically, the shielding cover 222a can prevent external dust, moisture, and other substances from entering the space where the circuit board 4 is located, reducing the probability of problems such as poor electrical connection due to dust accumulation or moisture corrosion. For example, in a humid environment, without the protection of the shield 222a, moisture may seep into the connection point between the circuit board 4 and the screen 21, causing a short circuit or oxidation, affecting the normal display of the screen 21. Furthermore, the shield 222a can reduce the direct impact of mechanical stress on the electrical connections. During equipment handling or use, the display device 10 may be subjected to impacts or pressure; the shield 222a can buffer these external forces, protecting the electrical connections from damage and ensuring that the screen 21 can stably receive signals transmitted from the circuit board 4 and display images normally.

[0077] Reference Figure 9 and Figure 10 In some embodiments, the shield 222a includes a shield body portion 222a1, the circuit board 4 is disposed between the shield body portion 222a1 and the support member 221, the rear shell 11 includes a recessed portion 113, the recessed portion 113 is offset from the shield body portion 222a1, and the recessed portion 113 is recessed relative to the shield body portion 222a1 toward the direction close to the screen body 21, the recessed portion 113 defines a groove 1131 that opens toward the direction away from the screen body 21, and the mounting end 201 of the support device 20 is assembled and connected to the adapter structure 22 in the groove 1131.

[0078] In the above technical solution, the recessed portion 113 of the rear shell 11 is offset from the cover portion 222a1 and is recessed towards the screen body 21, thereby making full use of the vertical space of the display device 10, enabling the display device 10 to accommodate more components, which helps to achieve miniaturization and thinning of the display device 10. The recessed portion 113 defines a groove 1131 that opens towards the direction away from the screen body 21, thereby providing a certain assembly space for the mounting end 201 of the support device 20, so that the mounting end 201 can extend into the groove 1131, reducing the exposed length of the support device 20 and improving the overall utilization rate of the internal space of the display device 10.

[0079] Reference Figure 10In some embodiments, the housing assembly 1 further includes a cable outlet cover 13, which is disposed within a groove 1131 and connected to the rear housing 11. The cable outlet cover 13 has a clearance opening 131 formed on it. Figure 6 The clearance opening 131 avoids the mounting end 201, and the recess 113 has a wire insertion port 1132. The line 5 passing through the clearance opening 131 is connected to the circuit board 4 through the wire insertion port 1132.

[0080] In the above technical solution, the cable outlet cover 13 is disposed in the groove 1131 and connected to the rear shell 11. For example, the cable outlet cover 13 covers the recess 113, thereby shielding the mounting end 201 at the assembly connection point with the adapter structure 22 in the groove 1131, improving the simplicity of the appearance of the display device 10. A clearance opening 131 is formed on the cable outlet cover 13, which avoids the mounting end 201, so that the mounting end 201 can pass through the cable outlet cover 13 and be assembled with the adapter structure 22. A wire insertion port 1132 is formed on the recess 113, through which the wire 5 passes. The connector 1132 is connected to the circuit board 4. The connector 1132 provides a connection channel for the connection between the line 5 and the circuit board 4. The line 5, which passes through the clearance opening 131, can be accurately connected to the corresponding interface on the circuit board 4 through the connector 1132, thereby facilitating the connection between the line 5 and the circuit board 4 and improving assembly efficiency. In addition, the connection between the cable outlet cover 13 and the rear shell 11 also provides a certain degree of physical protection for the line 5. The cable outlet cover 13 can reduce the possibility of the line 5 being directly squeezed or scratched, extend the service life of the line 5, and ensure the stability and reliability of the connection between the line 5 and the circuit board 4.

[0081] Reference Figure 8 and Figure 9 In some embodiments, the circuit board 4 is connected to the carrier 221 by a fourth fastener M4, and the shield 222a is detachably connected to the carrier 221 by a fifth fastener M5.

[0082] The circuit board 4 is connected to the carrier 221 by the fourth fastener M4, which can provide a stable support for the circuit board 4. For example, the fourth fastener M4 is set at the four corners of the circuit board 4. Thus, the fourth fastener M4 can improve the firmness of the connection between the circuit board 4 and the carrier 221, prevent the circuit board 4 from loosening or shifting, reduce signal interference, short circuits and other faults caused by the shaking of the circuit board 4, and improve the overall reliability of the equipment operation.

[0083] The shielding cover 222a and the carrier 221 are detachably connected via a fifth fastener M5. This detachable connection facilitates the installation and removal of the shielding cover 222a. During equipment assembly, the shielding cover 222a can be easily installed onto the carrier 221, improving assembly efficiency. During equipment maintenance, repair, or upgrades, the shielding cover 222a can be quickly removed to inspect, repair, or replace the circuit board 4 or other components inside, reducing maintenance costs and time. Furthermore, the fifth fastener M5 ensures a secure connection between the shielding cover 222a and the carrier 221, effectively utilizing the electromagnetic shielding function of the shielding cover 222a, reducing the impact of external electromagnetic interference on the circuit board 4, and protecting the normal operation of sensitive electronic components on the circuit board 4.

[0084] Reference Figure 8 and Figure 9 In some embodiments, the transition structure 22 includes a support member 221, which is disposed between the screen body 21 and the rear shell 11 and is connected to the screen body 21, with the screen body 21 supported by the support member 221. The support member 221 meets the connection requirements between the screen body 21 and the transition structure 22. Through the structural design of the support member 221, it provides a stable connection and support foundation for the screen body 21, effectively dispersing the weight and external forces borne by the screen body 21 and preventing the screen body 21 from deforming or being damaged due to uneven stress.

[0085] For example, the support member 221 in any of the above embodiments can be constructed as a screen bracket 221a. The screen bracket 221a includes a back plate 221a1 and a surrounding frame 221a2. The back plate 221a1 is located on the non-display side of the screen body 21. The surrounding frame 221a2 is connected to the edge of the back plate 221a1 and to the shell assembly 1. The surrounding frame 221a2 surrounds the screen body 21. The surrounding frame 221a2 is snapped into the screen body 21. And / or, the back plate 221a1 is connected to the screen body 21 by a sixth fastener M6.

[0086] In the above technical solution, the screen bracket 221a consists of a back plate 221a1 and a surrounding frame 221a2. The back plate 221a1 is located on the non-display side of the screen body 21, and the surrounding frame 221a2 surrounds the screen body 21 and is connected to the edge of the back plate 221a1, so that the screen bracket 221a provides all-round support and protection for the screen body 21. The back plate 221a1 can provide a certain support for the screen body 21, making the screen body 21 less prone to bending and damage, while the surrounding frame 221a2 protects the fragile and easily bumped parts such as the edges and corners of the screen body 21. Thus, the overall structure of the screen bracket 221a can effectively disperse external forces, reduce the deformation and damage of the screen body 21 caused by force, and thus extend the service life of the screen body 21. The surrounding frame 221a2 is connected to the shell assembly 1, further enhancing the protection of the screen body 21, and allowing the screen assembly 2 to be firmly fixed in the shell assembly 1, improving the connection reliability between the various components of the display device 10.

[0087] In the above technical solution, the frame 221a2 and the screen body 21 are engaged to prevent relative displacement between the screen body 21 and the frame 221a2 to a certain extent. The frame 221a2 of the screen bracket 221a surrounds the screen body 21 and can play a certain role in electromagnetic shielding, reducing the impact of external electromagnetic interference on the display effect of the screen body 21 and improving the display quality of the screen body 21.

[0088] In the embodiments of this application, the structure of the carrier 221 is not limited to the screen bracket 221a, but may also be flat, mesh, etc.

The circuit board 4 is connected to the support member 221 by a fourth fastener M4. The shielding cover 222a and the support member 221 are detachably connected by a fifth fastener M5. The connecting part 222a2 is connected to the support device 20 by a third fastener M3. The mating part 223 is disposed between the shielding cover 222a and the rear shell 11.

[0094] The back cover 11 includes a recess 113, which is offset from the cover 222a1 and recessed relative to the cover 222a1 toward the screen 21. The recess 113 defines a groove 1131 that opens toward the direction away from the screen 21. The mounting end 201 of the support device 20 forms a slot 2231 in the groove 1131 to engage with the mating part 223 and the shield 222a.

[0095] The housing assembly 1 also includes a cable outlet cover 13, which is disposed in the groove 1131 and connected to the rear housing 11. A clearance opening 131 is formed on the cable outlet cover 13, which avoids the mounting end 201. A wire insertion port 1132 is formed on the recess 113, and the wire 5 passing through the clearance opening 131 is connected to the circuit board 4 through the wire insertion port 1132.

[0096] The display device 10 can be assembled in the following order:

[0097] First, attach the buffer pad 3 to the inner frame of the front frame 12 to form the front frame assembly;

[0098] Then, the screen body 21 is mounted on the screen bracket 221a and fixed by the sixth fastener M6. At the same time, the circuit board 4 is mounted on the back plate 221a1 of the screen bracket 221a and fixed by the fourth fastener M4. The shielding cover 222a is placed on the circuit board 4 and fixed by the fifth fastener M5 to the back plate 221a1 of the screen bracket 221a, thus forming the screen assembly 2.

[0099] Next, the assembled screen assembly 2 is fastened to the back cover 11. The back cover 11 has a buckle on the inside, which is fastened to the frame 221a2 of the screen bracket 221a and fixed by the two first fasteners M1 on the bottom edge of the screen assembly 2.

[0104] In related technologies, ultrasonic equipment typically consists of a display screen and a housing. The housing includes a front shell and a rear shell. The display screen is fixed to the front or rear shell using screws to form an assembly, and then the housing is installed and fixed to a floating arm or bracket. However, when the display screen is locked to the front shell with screws, the locking force acts directly on the display screen, easily causing light leakage or water ripple effects. When the display screen is locked to the rear shell with screws, and the housing is then installed and fixed to the floating arm or bracket, the forces generated by bumps and vibrations act directly on the housing, easily causing the housing itself or the studs to break. Moreover, both of these assembly methods use a large number of screws for fixing, resulting in high assembly time and costs. The display device 10 of the above embodiment can effectively solve the above-mentioned technical problems.
