Technical Field

[0001] This application relates to the field of medical device technology, and more specifically, to a locking structure, a housing for an ultrasound diagnostic device, and the ultrasound diagnostic device itself. Background Technology

[0002] To meet the disassembly requirements of components in electronic devices and other products, these components need to be detachably installed. For detachable first and second connectors, they are often connected by screws. However, screw assembly is inefficient and cumbersome, making it difficult to meet the needs of rapid maintenance and modular upgrades in modern electronic equipment.

[0003] To enable rapid assembly and disassembly of the first and second connecting parts, some designs employ quick-release screwless assembly designs (such as clips, slide rails, etc.). Quick-release designs simplify the assembly and disassembly process, improve equipment maintainability and user experience, require no tools, support one-handed operation, reduce screw usage, and lower assembly time and material costs. However, quick-release methods have poor vibration reliability. Therefore, improving the vibration stability between the detachable first and second connecting parts is a problem that needs to be solved by those skilled in the art. Utility Model Content

Detailed Implementation

[0045] This application discloses a locking structure, a housing for an ultrasonic diagnostic device, and the ultrasonic diagnostic device itself, to enable rapid assembly and disassembly of the first connector and the second connector, and to improve its vibration stability.

[0046] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0047] The locking structure provided in this application is applicable to, but not limited to, the housing of an ultrasound diagnostic device. It can be used for detachable connections to other covers of ultrasound diagnostic devices, or for connections between two detachable components on other devices. For ease of explanation, the following embodiments use its application to the housing as an example.

[0048] In some embodiments, please refer to Figures 1-3 The locking structure provided in this application includes a lock cover 1 and a button assembly 2. The lock cover 1 is mounted on a first connecting member 3. The button assembly 2 cooperates with the lock cover 1 and includes a button housing 21, a button 22, and a hook 23. The button housing 21 is mounted on a second connecting member 4. Both the button 22 and the hook 23 are located on the button housing 21. The button 22 can move relative to the button housing 21 along a first direction, thereby causing the hook 23 to move along and rotate around the first direction to lock or unlock with the lock cover 1. The first direction is the direction in which the button 22 faces the lock cover 1. Through the cooperation of the button 22, the button housing 21, and the hook 23, when the button 22 moves along the first direction, it not only drives the hook 23 to move along the first direction but also allows the hook 23 to rotate around the first direction, thus switching the state with the lock cover 1, i.e., locking or unlocking it. The first connecting member 3 and the second connecting member 4 can be various cover structures, and the locking structure enables the connection between the two cover structures. Taking medical equipment as an example, the first connector 3 can be the main body of the chassis, the column, the operation panel, etc., and the second connector 4 can be a cover for connecting with the main body of the chassis, the column, the operation panel, etc.

[0049] When the second connector 4 is installed on the first connector 3 using the locking structure provided in this application, the button assembly 2 cooperates with the lock cover 1. Specifically, pressing the button 22 in the first direction causes the hook 23 to move in the first direction and rotate around it, thereby locking it with the lock cover 1. This secures the hook 23 to the lock cover 1, ensuring reliable fixation of the second connector 4 and the first connector 3. To unlock, pressing the button 22 again in the first direction causes the hook 23 to move and unlock from the lock cover 1, allowing the second connector 4 to be detached from the first connector 3. In summary, the locking structure provided in this application allows for quick assembly and disassembly of the first connector 3 and the second connector 4 simply by pressing the button 22, making operation convenient. Furthermore, the hook 23 locks with the lock cover 1, ensuring a stable and reliable connection between the first connector 3 and the second connector 4, thus improving the overall vibration stability of the two connectors.

[0050] In some embodiments, the button assembly 2 adopts a push-push structure, meaning that when the button 22 is pressed in the first direction, it drives the hook 23 to move in the first direction, and the hook 23 can rotate around the first direction and lock in the extended state. When the button 22 is pressed again, it drives the hook 23 to move in the first direction, and the hook 23 can rotate around the first direction and unlock, thereby allowing the hook 23 to retract to the initial state. For example, when the hook 23 is locked in the extended state, the hook 23 is unlocked from the lock cover 1; when the hook 23 is unlocked and retracted to the initial state, the hook 23 is locked from the lock cover 1, that is, in the initial state, the hook 23 fixes the second connecting member 4 to the first connecting member 3. The button assembly 2 adopts a push-push structure, which is convenient to operate and reliable in locking.

[0051] In some embodiments, please refer to Figures 3-7 The hook 23 has a limiting head 231 at the end away from the button 22, and the lock cover 1 has a limiting wall 11 with a locking hole 12 that mates with the limiting head 231. When the hook 23 is unlocked, the limiting head 231 can pass through the locking hole 12. When the hook 23 is locked, the hook 23 can pass through the locking hole 12 and the limiting head 231 abuts against the wall of the limiting wall 11 away from the button 22. Through the cooperation of the limiting wall 11 and the limiting head 231, when the limiting head 231 rotates to abut against the limiting wall 11, the hook 23 is locked to the lock cover 1. When the limiting head 231 rotates to face the locking hole 12 on the limiting wall 11, the hook 23 is unlocked from the lock cover 1, and the limiting head 231 can pass through the locking hole 12, thereby allowing the second connecting member 4 to be detached from the first connecting member 3. With the above configuration, the hook 23 and the lock cover 1 are reliably locked. The shapes of the limiting head 231 and the locking hole 12 can be set according to the needs. For example, if the limiting head 231 is in the shape of a cross, the locking hole 12 will be in the shape of a cross.

[0052] For example, the button assembly 2 adopts a push-push structure, and the end of the hook 23 facing the lock cover 1 is provided with a limiting head 231. The lock cover 1 is provided with a limiting wall 11, and a locking hole 12 that cooperates with the limiting head 231 is opened on the limiting wall 11. When the second connector 4 is installed, the hook 23 is locked in the extended state, and the hook 23 is unlocked from the lock cover 1. Therefore, the limiting head 231 passes through the locking hole 12. Then, the button 22 is pressed in the first direction, and the hook 23 is unlocked and retracted to the initial state. At the same time, the limiting head 231 abuts against the wall surface of the limiting wall 11 facing the lock cover 1. The limiting head 231 cannot be dislodged from the locking hole 12, and the hook 23 is locked to the lock cover 1. When the second connector 4 is disassembled, the button 22 is pressed in the first direction, the hook 23 is locked in the extended state again, and the hook 23 is unlocked from the lock cover 1. The limiting head 231 is pulled out from the locking hole 12, and the second connector 4 is disassembled from the first connector 3.

[0053] In some embodiments, please refer to Figures 3-7The lock cover 1 is provided with a receiving groove 13, and one end of the button housing 21 can be inserted into the receiving groove 13. The bottom of the receiving groove 13 is a limiting wall 11. It can be understood that the bottom of the receiving groove 13 refers to the wall surface of the receiving groove 13 opposite to the button housing 21 along the first direction. The shape of the receiving groove 13 corresponds to the shape of one end of the button housing 21. For example, if one end of the button housing 21 is cylindrical, the receiving groove 13 is correspondingly cylindrical. Through the setting of the receiving groove 13, it can cooperate with the button housing 21. That is, when the second connector 4 is installed, the button housing 21 is inserted into the receiving groove 13 to play a role in positioning and guiding the button assembly 2 and the second connector 4, thereby facilitating the quick and reliable installation of the second connector 4.

[0054] In some embodiments, please refer to Figures 3-7 The button assembly 2 includes an elastic element 24 disposed between the hook 23 and the button housing 21. The elastic element 24 provides a force to the hook 23 in a second direction, which is parallel to and opposite to the first direction. By utilizing the restoring force of the elastic element 24 on the hook 23, the movement of the hook 23 becomes smoother, and the hook 23 can be stably maintained in its retracted initial state when no external force is applied. For example, when the button 22 moves the hook 23 along the first direction and rotates it around the first direction to an angle corresponding to the locking of the cover 1, the elastic element 24 causes the hook 23 to retract, thereby causing the limiting head 231 to abut against the wall of the limiting wall 11 facing the cover 1. The elastic element 24 can specifically be a spring, such as a coil spring, or other elastic elements 24 or materials capable of providing restoring force.

[0055] In some embodiments, please refer to Figures 3-7The button housing 21 includes a base 211 and an end cap 212. The base 211 includes a first cylindrical body 2111 and a first flange 2112 located at one end of the first cylindrical body 2111. The first flange 2112 has a fixing portion and is fixedly connected to the second connecting member 4. The end cap 212 includes a second cylindrical body 2121 and a second flange 2122 located at one end of the second cylindrical body 2121. The second cylindrical body 2121 is inserted into the first cylindrical body 2111. The outer side of the second flange 2122 abuts against the end face of the first cylindrical body 2111, and the inner side of the second flange 2122 abuts against the elastic member 24. The middle portion of the second flange 2122 forms an opening for the hook 23 to pass through. The button housing 21 adopts a split structure to facilitate the installation of the hook 23, the elastic member 24, and the button 22. The base 211 is provided with the first flange 2112 for easy fixed connection with the second connecting member 4. The fixing part may specifically include screw holes, that is, the base 211 is screwed to the second connecting member 4. The end cap 212, through the setting of the second flange 2122, can both abut against the elastic member 24 to provide support force, and abut against the first cylinder 2111 to limit the position. With this configuration, the button housing 21 has a simple and compact structure, and the components fit together stably and reliably. For example, the base 211 and the end cap 212 are threaded together, which is convenient for disassembly and assembly.

[0056] In some embodiments, please refer to Figures 8-11The button housing 21 has a mounting hole, and the button 22 is disposed in the mounting hole. The inner circumferential surface of the mounting hole has a plurality of sliding grooves 213 extending in a first direction. The plurality of sliding grooves 213 are evenly distributed in the circumferential direction, and a first tooth surface 214 is provided between each adjacent sliding groove 213. The end of the button 22 facing the hook 23 has a plurality of wedge-shaped portions 221 evenly distributed in the circumferential direction. The outer circumferential surface of one end of the hook 23 has a protrusion 232 that cooperates with the sliding groove 213. The end of the protrusion 232 facing the button 22 is a second tooth surface 233 for cooperating with the first tooth surface 214 and the wedge-shaped portion 221. When the hook 23 is locked, the protrusion 232 is located in the sliding groove 213, and the second tooth surface 233 engages with the wedge-shaped portion 221. When the hook 23 is unlocked, the second tooth surface 233 engages with the first tooth surface 214. When button 22 moves relative to button housing 21 in the first direction, wedge-shaped portion 221 and second toothed surface 233 cooperate to push protrusion 232 along slide groove 213 until it disengages from slide groove 213 and rotates at a preset angle. At this point, hook 23 moves in the second direction under the action of elastic member 24 until second toothed surface 233 engages with first toothed surface 214. Hook 23 is locked in an extended state to facilitate assembly of second connector 4 and first connector 3. After second connector 4 is assembled, button 22 is pressed again in the first direction. Wedge-shaped portion 221 pushes second toothed surface 233 away from first toothed surface 214 to unlock and rotate hook 23 at a certain angle so that protrusion 232 is opposite slide groove 213. Under the action of elastic member 24, protrusion 232 enters slide groove 213 in the second direction and slides along slide groove 213 until it returns to its initial position. At this point, hook 23 is in a retracted state to lock with lock cover 1. The button assembly 2 adopts the above-described structure, which is simple, occupies little space, and has reliable transmission. In other embodiments, the button assembly 2 may also employ other push-push structures, such as a heart-shaped groove on the button housing 21. To prevent the button 22 from rotating, a protrusion 222 is provided on the outer peripheral surface of the button 22, and a limiting groove 215 that mates with the protrusion 222 is provided on the button housing 21.

[0057] For example, please refer to Figures 4-12 The unlocking process of hook 23 and lock cover 1 is as follows: When button 22 is pressed, the wedge-shaped part 221 on button 22 contacts the second toothed surface 233 on hook 23. After sliding down the slide along the groove 213 for a designed stroke S1, due to the eccentricity between the tip of the wedge-shaped part 221 and the center position of the second toothed surface 233, as... Figure 12 As shown, under the pressure of the eccentricity and the elastic element 24, the second tooth surface 233 will rotate slightly and then get into the first tooth surface 214 to complete the angular rotation and return part of the stroke S2. This stroke is less than the downward design stroke S1 mentioned above. Under the pressure of the elastic element 24, the hook 23 and the lock cover 1 are separated and unlocked. The distance that the hook 23 slides down is S1-S2.

[0058] The locking process between hook 23 and lock cover 1 is as follows: When button 22 is pressed again, the second tooth surface 233 will disengage from the first tooth surface 214. When the travel of button 22 reaches S2, under the action of eccentricity and elastic element 24 pressure, the second tooth surface 233 will slide up along the inclined surface 216 into the slide groove 213 to complete the angle rotation. At this time, button 22 slides up again under the action of elastic element 24 to restore the travel of S1. The distance of the upward slide is S1-S2.

[0059] It is understandable that the degree of rotation of hook 23 each time is related to the number of wedges 221 on button 22.

[0060] This application also provides a housing for an ultrasound diagnostic device, which can adopt any of the locking structures described in the above embodiments.

[0061] Ultrasonic diagnostic equipment is a commonly used instrument in the medical field. The chassis, as a crucial component of this equipment, integrates various requirements including protection, electromagnetic compatibility, heat dissipation, human-machine interaction, and medical compliance. It typically consists of side shells, front shells, top shells, and rear shells. Traditionally, the chassis of an ultrasonic main unit is assembled with screws. Currently, chassis circuit boards are usually quickly disassembled and repaired from the rear shell, thus the rear shell is detachably connected to the main body. This application optimizes the connection structure between the rear shell and the main body by combining a snap-fit ​​structure with a locking structure, strengthening the fixation of the rear shell. This allows for both rapid assembly and disassembly while providing good vibration stability and ensuring the flatness of the chassis exterior. The following embodiments primarily describe the connection structure between the rear shell and the main body.

[0062] In some embodiments, please refer to Figures 1-3 The ultrasonic diagnostic equipment enclosure provided in this application includes a main enclosure, a rear shell, a female latch 6, a male latch 5, and a locking structure. The main enclosure is the aforementioned first connector 3, and the rear shell is the aforementioned second connector 4. The structure of the main enclosure can refer to conventional enclosure designs and is not specifically limited here. For example, it is a box-like structure. The rear shell is used to install on the rear side of the main enclosure, specifically on the side of the main enclosure used for installing and removing circuit boards.

[0063] The female latch 6 and the locking cover 1 are respectively located on the main body of the chassis. The male latch 5 is located on the rear shell and is used to engage with the female latch 6. The male latch 5 and the female latch 6 are a pair of mating snap-fit ​​structures. For example, one is provided with a slot and the other is provided with a snap head. When the rear shell is installed, the snap head engages in the corresponding slot. The main body of the chassis includes a portion of the wall opposite the rear shell for mounting the locking cover 1.

[0064] The locking structure comprises a lock cover 1 and a button assembly 2, which cooperates with the lock cover 1. The button assembly 2 includes a button housing 21, a button 22, and a hook 23. The button housing 21 is located on the rear cover, and both the button 22 and the hook 23 are located on the button housing 21. The button 22 can move relative to the button housing 21 along a first direction, thereby driving the hook 23 to move along and rotate around the first direction to lock or unlock with the lock cover 1. The first direction is the direction in which the button 22 faces the lock cover 1. Through the cooperation of the button 22, the button housing 21, and the hook 23, when the button 22 moves along the first direction, it can not only drive the hook 23 to move along the first direction, but also allow the hook 23 to rotate around the first direction, thereby switching the state with the lock cover 1, i.e., locking or unlocking with the lock cover 1.

[0065] When the rear shell of the ultrasound diagnostic equipment provided in this application is installed on the main body of the chassis, the male buckle 5 on the rear shell engages with the female buckle 6 on the main body of the chassis. At the same time, the hook 23 of the button assembly 2 on the rear shell is locked to the lock cover 1 by pressing the button 22 in the first direction, that is, the hook 23 is fixed to the lock cover 1, thereby fixing the rear shell to the main body of the chassis.

[0066] In summary, the rear shell of the ultrasound diagnostic equipment provided in this application can be fixed to the main body of the chassis by means of the interlocking action of the male buckle 5 and the female buckle 6, and by means of the locking action of the button assembly 2 and the locking cover 1. The combination of the interlocking action and the locking action makes the fixation of the rear shell more stable and reliable, and improves the vibration stability of the ultrasound diagnostic equipment.

[0067] In some embodiments, when a limiting head 231 is provided at the end of the hook 23 away from the button 22, and the lock cover 1 is provided with a limiting wall 11, and a locking hole 12 that cooperates with the limiting head 231 is provided on the limiting wall 11, when the rear cover is installed, the male buckle 5 on the rear cover engages with the female buckle 6 of the chassis body. During installation, the hook 23 is first in the unlocked state from the lock cover 1. Therefore, while the male buckle 5 engages with the female buckle 6, the limiting head 231 passes through the locking hole 12. Then, the button 22 is pressed along the first direction. The button 22 drives the hook 23 to move along the first direction and rotate around the first direction. As a result, the limiting head 231 abuts against the wall surface of the limiting wall 11 facing the lock cover 1. The limiting head 231 cannot come out of the locking hole 12, thus achieving reliable locking of the hook 23 and the lock cover 1, thereby achieving another connection between the rear cover and the chassis body. When disassembling the rear cover, press button 22 in the first direction. Button 22 drives hook 23 to move in the first direction and rotate around the first direction, so that the limiting head 231 is aligned with the lock hole 12 to unlock. Pull the limiting head 231 out of the lock hole 12, and at the same time, the male buckle 5 and the female buckle 6 are disengaged, and the rear cover is removed from the main body of the chassis.

[0068] In some embodiments, the button housing 21 is located on the side of the rear shell facing the main body of the chassis, and a through hole is provided on the rear shell, through which the button 22 passes. Positioning the button housing 21 on the side of the rear shell facing the main body of the chassis does not affect the flatness of the other side of the rear shell, making it more aesthetically pleasing and safer, reducing the risk of accidental bumps. For ease of user operation, a through hole is provided on the rear shell, through which the button 22 passes. Exemplarily, the button 22 protrudes from the rear shell, allowing the user to easily press it. In other examples, the button 22 may be flush with or slightly lower than the rear shell, allowing the user to press the button 22 by inserting a finger into the through hole or by using a tool.

[0069] In some embodiments, the main body of the chassis is provided with a first magnetic part, and the rear shell is provided with a second magnetic part. The first magnetic part is used to magnetically engage with the second magnetic part to fix the rear shell to the main body of the chassis. By further providing the cooperating first and second magnetic parts on the main body of the chassis and the rear shell, the magnetic attraction between the two is combined to form another layer of bonding between the main body of the chassis and the rear shell, making the fixation of the rear shell to the main body of the chassis more stable and reliable, and improving the vibration stability of the ultrasound diagnostic equipment. For example, the first magnetic part and the second magnetic part can both be magnets, or one can be a magnet and the other can be a magnetic component that can be magnetically attracted to a magnet, such as an iron sheet.

[0070] In some embodiments, a plurality of male buckles 5 are spaced apart along the edge of the rear housing, and a second magnetic part is located at the edge of the rear housing and between adjacent male buckles 5. By placing the male buckles 5 and the second magnetic part at the edge of the rear housing and the button assembly 2 at the center of the rear housing, it can be fixed to the chassis body from both the center and the edge of the rear housing, resulting in greater stability and reliability. Furthermore, placing the male buckles 5 and the second magnetic part at the edge of the rear housing better secures the edge of the rear housing, preventing warping. Additionally, the male buckles 5 and the second magnetic part are spaced apart, so even if one is damaged, the other can still provide reliable fixation, ensuring effective fixation of the rear housing edge.

[0071] Based on the chassis housing provided in the above embodiments, this application also provides an ultrasound diagnostic device, which includes any of the chassis housings described in the above embodiments. Since this ultrasound diagnostic device uses the chassis housing described in the above embodiments, the beneficial effects of this ultrasound diagnostic device are explained in the above embodiments.
