Description

Technical Field

[0001] This application relates to the field of medical device technology, and in particular to a quick-release structure and medical device. Background Technology

[0002] With the development of lightweight portable medical devices (such as ultrasound diagnostic instruments and monitors), the internal space of these devices is becoming increasingly compact. In existing portable medical devices, the structural base plate of the battery cover is fixed to the main unit of the battery cover using screws. Although this method can stably fix the battery cover, special tools are required when removing and replacing the battery, resulting in low battery replacement efficiency and operational risks in emergency medical scenarios. Utility Model Content

[0003] Therefore, it is necessary to provide a quick-release structure and medical device to address the problem that battery replacement requires special tools, resulting in low battery replacement efficiency in related technologies.

[0004] In a first aspect, embodiments of this application provide a quick-release structure, the quick-release structure comprising:

[0005] The mounting housing has a receiving cavity and an opening communicating with the receiving cavity;

[0006] The cover is slidably disposed on the mounting housing to open or close the opening in a first direction;

[0007] The locking mechanism includes a pressing component and a reset component, the reset component being used to provide a reset force to the pressing component;

[0008] The cover is adapted to switch between a locked state and a released state. In the locked state, the pressing component and the cover are continuously engaged under the reset force of the reset component. In the released state, the pressing component releases the cover under the action of an external force and causes the reset component to store force.

[0009] In one embodiment, the reset assembly connects the pressing assembly and the mounting housing;

[0010] The cover is provided with a first positioning component at one end along the first direction; the pressing assembly is provided with a second positioning component; in the locked state, the first positioning component and the second positioning component are adapted and engaged; in the released state, the pressing assembly drives the second positioning component to move along the second direction under the action of external force, so as to release the first positioning component.

[0011] In one embodiment, the side surface of the mounting housing adjacent to the opening is a mounting surface, the mounting surface is provided with a mounting hole, and the locking mechanism is disposed in the mounting hole;

[0012] In the locked state, the pressing component is reset to the mounting surface by the action of the reset component.

[0013] In one embodiment, the mounting housing further includes a stop plate located within the mounting hole; the reset assembly is disposed on the stop plate.

[0014] In one embodiment, the reset assembly includes a reset spring, one end of which is limited to the stop plate and the other end of which is limited to the pressing assembly.

[0015] In one embodiment, the reset assembly further includes a limiting post, one end of which is fixed to the stop plate and the other end of which is movably inserted into the pressing assembly; the reset spring is sleeved on the limiting post.

[0016] In one embodiment, the pressing assembly includes a pressing block and a connector;

[0017] The connector is fixedly connected to the pressing block, and the connector is provided with a second positioning component at one end along the first direction.

[0018] In one embodiment, in the locked state, the side of the pressing block facing away from the reset assembly is flush with the mounting surface.

[0019] In one embodiment, the first positioning component and the second positioning component are mutually adaptable and interlocking concave-convex structures;

[0020] And / or, the second positioning component has a guide surface on the side facing the cover, the guide surface being configured to cause the pressing component to move away from the mounting surface under the push of the cover, so that the first positioning component and the second positioning component automatically engage;

[0021] And / or, the cover has an extension at one end along a first direction, and the first positioning member is formed in the extension.

[0022] Secondly, embodiments of this application provide a medical device, which includes the quick-release structure described in the above embodiments.

[0023] The aforementioned quick-release structure and medical device, through a reset component, mounts the pressing component onto the mounting housing. The reset component continuously provides a reset force, maintaining the pressing component in a continuous engagement with the cover. When the cover needs to be released, external force is applied to the pressing component, causing it to move and detach from the cover. At this point, the cover is released from constraint and can slide freely out of the opening along the first direction. In this embodiment, the locking mechanism can be unlocked by pressing in a direction perpendicular to the first direction. Since only the pressing component and reset component are provided in the pressing direction, the thickness is reduced compared to traditional quick-release structures, meeting the requirements for ultra-thin portable devices. Furthermore, the intersecting motion decoupling design makes the unlocking action independent of the opening action, allowing the cover to be released with a single press, making operation simpler and faster, and eliminating the need for special tools. Additionally, the quick-release structure provided in this embodiment has fewer components, which helps improve assembly efficiency and reduce costs. Attached Figure Description

[0033] To make the above-mentioned objectives, features, and advantages of this application more apparent and understandable, the specific embodiments of this application are described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of this application. However, this application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this application. Therefore, this application is not limited to the specific embodiments disclosed below.

[0034] In the description of this application, it should be understood that if terms such as "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential" appear, these terms indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.

[0035] Furthermore, where the terms "first" and "second" appear, these terms are for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined with "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this application, where the term "multiple" appears, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0036] In this application, unless otherwise expressly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise expressly limited. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0037] In this application, unless otherwise expressly specified and limited, the use of descriptions such as "above" or "below" the second feature indicates that the first and second features are in direct contact or indirect contact via an intermediate medium. Furthermore, "above," "on top of," and "over" the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply that the first feature is at a higher horizontal level than the second feature. Similarly, "below," "below," and "under" the second feature can mean that the first feature is directly below or diagonally below the second feature, or simply that the first feature is at a lower horizontal level than the second feature.

[0038] It should be noted that if an element is referred to as being "fixed to" or "set on" another element, it can be directly on the other element or there may be an intervening element. If an element is considered to be "connected to" another element, it can be directly connected to the other element or there may be an intervening element. If so, the terms "vertical," "horizontal," "upper," "lower," "left," "right," and similar expressions used in this application are for illustrative purposes only and do not represent the only possible implementation.

[0039] As mentioned in the background section, existing battery cover installation methods, besides screw fixing, also include some quick-release structures, such as the paddle-type quick-release structure. These structures mainly rely on spring return to achieve automatic locking, and the stop structure restricts the displacement of the battery cover. The limit is released by the paddle switch. This type of quick-release structure has a large number of parts, resulting in a large stacking space requirement, which conflicts with the trend of miniaturization of portable devices. In addition, assembly requires special fixtures to position the springs and paddles, making the manufacturing process complex and costly.

[0040] To address the aforementioned problems, this application provides a quick-release structure and medical device. A reset component mounts a pressing component onto the mounting housing, continuously providing a reset force to keep the pressing component locked to the cover. When the cover needs to be released, external force is applied to the pressing component, causing it to move and detach from the cover. The cover is then released from its constraint and can slide freely out of the opening along a first direction. In this embodiment, the locking mechanism can be unlocked by pressing in a direction perpendicular to the first direction. Since only the pressing component and reset component are present in the pressing direction, the thickness is reduced compared to traditional quick-release structures, meeting the requirements for ultra-thin portable devices. Furthermore, the intersecting motion decoupling design makes the unlocking action independent of the opening action, allowing the cover to be released with a single press, making operation simpler and faster, and eliminating the need for special tools. Additionally, the quick-release structure provided in this embodiment has fewer components, which helps improve assembly efficiency and reduce costs.

[0041] See Figure 1 and Figure 2 , Figure 1This is a cross-sectional view of a quick-release structure provided according to some embodiments of this application. Figure 2 This is a schematic diagram illustrating the disassembly structure of a quick-release structure provided according to some embodiments of this application. One embodiment of this application first provides a quick-release structure that can be applied to medical devices, for example, to enable the rapid installation and removal of battery covers on medical devices, or to enable the rapid sealing and replacement of consumable module covers (such as blood glucose meter test strip compartments, infusion pump medicine box compartments, etc.). Of course, besides medical devices, the quick-release structure provided in this embodiment can also be applied to fields such as industrial testing instruments and outdoor equipment where lightweighting and frequent battery replacement are required; no specific limitations are made here. The quick-release structure may include a mounting housing 100, a cover 200, and a locking mechanism 300.

[0042] The mounting housing 100 has a receiving cavity 101 and an opening 104 communicating with the receiving cavity 101; the cover 200 is slidably disposed on the mounting housing 100 to open or close the opening 104 in a first direction (X direction); the locking mechanism 300 includes a pressing component 310 and a reset component 320, the reset component 320 being used to provide a reset force to the pressing component 310; the cover 200 is adapted to switch between a locked state and a released state, in the locked state, the pressing component 310 and the cover 200 are continuously engaged under the action of the reset force of the reset component 320; in the released state, the pressing component 310 releases the cover 200 under the action of an external force and causes the reset component 320 to store force.

[0043] It is understood that the mounting housing 100 in this embodiment may refer to the main housing of the medical device, and the receiving cavity 101 formed on the mounting housing 100 is used to accommodate the battery or other functional modules. The top of the mounting housing 100 may have a rectangular opening 104, and guide rail grooves extending in the first direction (X direction) may be processed on both sides of the opening 104 so that the cover 200 can be embedded in the guide rail groove and slide in the first direction (X direction) to open or close the opening 104.

[0044] The cover 200 can be designed as a rectangular plate that matches the shape and size of the opening 104. Fixed sliders can be provided on both sides of its bottom to fit into guide grooves on both sides of the opening 104, allowing the cover 200 to slide open and close along the first direction (X-direction). In one example, a first positioning component 210 is provided at one end of the cover 200 along the first direction (X-direction). Specifically, by providing the first positioning component 210 at one end of the cover 200 along the first direction (X-direction) (near the edge of the mounting housing 100 after closing), the first positioning component 210, in cooperation with the locking mechanism 300, can lock or release the cover 200. Exemplarily, the first positioning component 210 can be a slot, a mating hole, and its shape can be L-shaped, rectangular, or other shapes, without limitation.

[0045] The locking mechanism 300 may include a pressing component 310 and a resetting component 320. The pressing surface of the pressing component 310 needs to be exposed on the outer surface of the mounting housing 100 to facilitate manual pressing operation. In order to lock the cover 200, in one embodiment, a second positioning component 3121 is provided on the pressing component 310. The second positioning component 3121 may be designed as a hook-shaped structure (hereinafter the limiting block) that is adapted to engage with the slot or mating hole. Under the release force of the resetting component 320, the pressing component 310 can be kept in a fixed position, that is, the second positioning component 3121 is continuously engaged with the first positioning component 210, so that the cover 200 is fixed on the mounting housing 100. When it is necessary to open the opening 104 so that the cover 200 moves away from the locking mechanism 300 in the first direction (X direction), an external hand presses the pressing component 310 in the second direction (Y direction). This causes the second positioning component 3121 to disengage from the first positioning component 210, releasing the first positioning component 210 and placing the cover 200 in a released state. After the first positioning component 210 is removed from the locking mechanism 300, the external hand can release the pressing component 310. The pressing component 310 will return to its fixed position under the reset action of the reset component 320 until the cover 200 and the first positioning component 210 trigger the locking mechanism 300 again.

[0046] More specifically, when the cover 200 is in the locked state, the reset assembly 320 elastically pushes the pressing assembly 310 upward (along the second direction (Y direction)) to a fixed position. In one example, the first positioning member 210 and the second positioning member 3121 are fitted and engaged. This process can be that the second positioning member 3121 (e.g., a hook-like structure) moves upward and engages with the first positioning member 210 (slot or mating hole) from below, thereby forming a mechanical interlock and locking the cover 200. When the cover 200 is in the released state, in one example, the pressing assembly 310, under the action of external force, drives the second positioning member 3121 to move along the second direction to release the first positioning member 210. Specifically, the process requires an external hand to press the pressing component 310. At this time, the pressing component 310 moves down along the second direction (Y direction), and the second positioning component 3121 moves down until it is dislodged from the first positioning component 210. The cover 200 is released from its constraint and can slide freely out of the opening 104 along the first direction (X direction). At the same time, the reset component 320 is in a charging state. When the hand is removed, the pressing component 310 will return to its original position (corresponding to the fixed position in the locked state) under the elastic force of the reset component 320, so as to facilitate the next use.

[0047] Regarding the working principle of the locking mechanism 300 for the next use, it can be that an external hand can press the pressing component 310, causing the second positioning component 3121 to make room. That is, after the first positioning component 210 reaches the locked position, the hand is removed, and the second positioning component 3121 and the first positioning component 210 are locked under the reset of the reset component 320. Of course, in order to save the operation of pressing the pressing component by hand and further improve the convenience of operation, a guide surface 3122 can be designed on the side of the second positioning component 3121 facing the cover 200. After the cover 200 releases the guide surface 3122, a separation along the second direction (Y direction) is generated to compress the reset component 320 to move downward, so that the first positioning component 210 can slide over the guide surface 3122 and engage with the second positioning component 3121. At the same time, the reset component 320 resets and locks the first positioning component 210.

[0048] The quick-release structure provided in this application embodiment uses a first positioning component 210 at one end of the cover 200 along the first direction (X direction) and a second positioning component 3121 on the pressing component 310 to keep the cover 200 in a locked state by engaging the first positioning component 210 and the second positioning component 3121 along the second direction (Y direction). Specifically, the pressing component 310 is installed on the mounting housing 100 by the reset component 320, so that the reset component 320 continuously provides elastic force to engage the second positioning component 3121 with the first positioning component 210. When it is necessary to release the cover 200, the pressing component 310 is pressed by external force, so that the second positioning component 3121 moves along the second direction (Y direction) to disengage from the first positioning component 210. At this time, the cover 200 is released from constraint and can slide freely out of the opening 104 along the first direction (X direction). In this embodiment, the locking mechanism 300 is unlocked by pressing along the second direction (Y direction). Since only the pressing component 310 and the reset component 320 are provided in the second direction (Y direction), the thickness is reduced compared to the traditional quick-release structure, meeting the requirements of ultra-thin portable devices. Furthermore, the intersecting motion decoupling design makes the unlocking action independent of the opening action, allowing the cover 200 to be released with a single press, making the operation simpler and faster, and eliminating the need for special tools. In addition, the quick-release structure provided in this embodiment has fewer parts, which helps to improve assembly efficiency and reduce costs.

[0049] Below, we will combine the appendix Figure 1 -Appendix Figure 4 The specific structure of the quick-release structure provided in the embodiments of this application will be described in detail.

[0050] like Figure 1 and Figure 2As shown, in some embodiments, the side surface of the mounting housing 100 adjacent to the opening 104 is defined as the mounting surface 102. The mounting surface 102 is provided with a mounting hole 103, and the locking mechanism 300 is disposed in the mounting hole 103. In the locked state, the pressing component 310 is reset to the mounting surface 102 under the action of the reset component 320.

[0051] It is understood that in this example, the mounting surface 102 and the opening 104 are located on the same surface of the mounting housing 100, for example, both are located on the top of the mounting housing 100. The mounting surface 102 is located on the top surface of the mounting housing 100 adjacent to the opening 104. This arrangement facilitates manual operation for unlocking and opening or closing the cover 200. The mounting surface 102 is machined with a mounting hole 103 that communicates with the interior of the mounting housing 100. The mounting hole 103 can be rectangular or circular, and there is no limitation here, so as to accommodate both the pressing component 310 and the reset component 320 of the locking mechanism 300 within the mounting hole 103, thereby forming a compact layout and facilitating a smooth appearance.

[0052] When locked, the spring force of the reset component 320 pushes the pressing component 310 to reset, causing the surface of the pressing component 310 to be flush with the mounting surface 102, away from the surface of the reset component 320. This design, on the one hand, prevents the pressing component 310 from protruding from the mounting surface 102, avoiding accidental locking due to contact, and is especially suitable for scenarios with high stability requirements, such as medical equipment; on the other hand, keeping the mounting surface 102 flat improves the aesthetics and grip of the device.

[0053] like Figure 1 As shown, in some embodiments, the mounting housing 100 further includes a stop plate 110 located within the mounting hole 103; the reset assembly 320 is disposed on the stop plate 110.

[0054] Specifically, a stop plate 110 is integrally formed or fixedly connected inside the mounting hole 103, such as an annular plate or strip plate extending radially along the mounting hole 103. The stop plate 110 is mainly used to carry and support the locking mechanism 300. One end of the reset assembly 320 (e.g., reset spring 321) is fixed or limited to the stop plate 110, and the other end is connected to the pressing assembly 310.

[0055] In this embodiment, the stop plate 110 provides a stable mounting reference for the reset assembly 320, preventing the reset assembly 320 from shaking or shifting within the mounting hole 103, and ensuring that the elastic force direction of the reset assembly 320 is always along the second direction (Y direction) (intersecting with the sliding direction of the cover 200), thereby ensuring the movement stability of the pressing assembly 310. Furthermore, the stop plate 110 can also limit the reset stroke of the pressing assembly 310, preventing it from over-resetting and dislodging from the mounting hole 103, thus improving structural reliability. Of course, the quick-release structure provided in this embodiment can also prevent the pressing assembly 310 from dislodging from the mounting hole 103 in other ways, as detailed in the following examples, which will not be elaborated further here.

[0056] like Figure 2 As shown, in some embodiments, the reset assembly 320 includes a reset spring 321, one end of which is limited to the stop plate 110 and the other end is limited to the pressing assembly 310.

[0057] Specifically, the reset assembly 320 uses a reset spring 321 as an elastic reset element. One end of the reset spring 321 can abut or lock onto the stop plate 110. For example, the stop plate 110 is provided with a spring positioning groove to fix the bottom of the reset spring 321. The other end of the reset spring 321 abuts or locks onto the inner wall of the pressing assembly 310. For example, the pressing assembly 310 is provided with a corresponding spring positioning post to fix the top of the reset spring 321.

[0058] In the locked state, the return spring 321 is in a slightly compressed state, and its elastic force pushes the pressing component 310 to move towards the mounting surface 102, so that the second positioning component 3121 engages with the first positioning component 210; when the pressing component 310 is subjected to external force and moves along the second direction (Y direction) (towards the inside of the mounting hole 103), the return spring 321 is compressed and stores force; after the external force is removed, the elastic force of the return spring 321 drives the pressing component 310 to reset and restore the locked state.

[0059] In this embodiment, the reset spring 321 has a simple structure, low cost, and stable elastic force, which can reliably realize the automatic reset of the pressing component 310. At the same time, it reduces the number of parts in the locking mechanism 300 and facilitates assembly.

[0060] like Figure 2 As shown, in some embodiments, the reset assembly 320 further includes a limiting post 322, one end of which is fixed to the stop plate 110, and the other end is movably inserted into the pressing assembly 310; the reset spring 321 is sleeved on the limiting post 322.

[0061] It is understood that one end of the limiting post 322 is fixed to the stop plate 110, and the other end extends along the second direction (Y direction) and movably passes through the through hole of the pressing assembly 310. The return spring 321 is sleeved on the outside of the limiting post 322, and its two ends are respectively limited to the stop plate 110 and the pressing assembly 310. In one example, there are two limiting posts 322 and two return springs 321, symmetrically distributed on both sides of the pressing assembly 310.

[0062] In this embodiment, the limiting post 322 provides guidance for the movement of the pressing component 310, preventing the return spring 321 from bending laterally during compression or extension (especially when the pressing component 310 is subjected to uneven force), ensuring that the pressing component 310 moves smoothly along the second direction (Y direction) and avoiding jamming. The two symmetrically distributed return springs 321 and limiting post 322 can further balance the force on the pressing component 310, reduce the risk of skewing, and make the engagement between the second positioning component 3121 and the first positioning component 210 more precise, thereby improving the locking reliability.

[0063] like Figure 2 As shown, in some embodiments, the pressing assembly 310 includes a pressing block 311 and a connecting member 312. The pressing block 311 is adapted to pass through the mounting hole 103. In the locked state, the side of the pressing block 311 facing away from the reset assembly 320 is flush with the mounting surface 102. The connecting member 312 is fixedly connected to the pressing block 311. One end of the connecting member 312 along the first direction (X direction) is provided with a second positioning member 3121.

[0064] Specifically, the pressing assembly 310 consists of a pressing block 311 and a connector 312. The pressing block 311 is a block-shaped structure adapted to the shape of the mounting hole 103, such as a plastic or metal block with the same shape as the mounting hole 103. Its edge is clearance-fitted with the inner wall of the mounting hole 103, allowing it to slide smoothly along the second direction (Y direction). The side of the pressing block 311 facing away from the reset assembly 320 is flush with the mounting surface 102 in the locked state to prevent protrusion.

[0065] The connecting member 312 (e.g., a strip plate) is fixedly connected to the pressing block 311 by screws or clips, and extends along the first direction (X direction). The end of the connecting member 312 away from the pressing block 311 is provided with a second positioning member 3121 (e.g., a limiting block). When the pressing block 311 is pressed, the connecting member 312 moves along the second direction (Y direction) with the pressing block 311, causing the second positioning member 3121 to move synchronously, thereby separating from the first positioning member 210.

[0066] In this embodiment, the pressing block 311 and the connecting piece 312 have a clear division of labor. The pressing block 311 is responsible for receiving external force, and the connecting piece 312 is responsible for transmitting motion and bearing the second positioning component 3121. The structure is modular, which is convenient for processing and assembly. At the same time, the design of the pressing block 311 being flush with the mounting surface 102 further optimizes the operational safety and the appearance of the equipment.

[0067] It should be noted that a fingerprint groove (such as a pattern) can be set on the upper surface of the pressing block 311 to guide blind operation and improve the success rate of unlocking when the user is wearing medical gloves.

[0068] like Figure 4 As shown, Figure 4 This is a bottom view of a quick-release structure provided according to some embodiments of this application. In some embodiments, the projected area of ​​the connector 312 along the second direction (Y direction) is larger than the area of ​​the mounting hole 103; in the locked state, a portion of the mounting surface located on one side of the pressing block 311 contacts the surface of the mounting housing 100;

[0069] Specifically, the projected area of ​​the connector 312 along the second direction (Y direction) is larger than the area of ​​the mounting hole 103 to form a retaining edge structure. In one example, the connector 312 includes a mounting surface opposite to the reset assembly 320, the mounting surface being constructed with a recessed groove, and the pressing block 311 being adapted to be installed in the recessed groove. The mounting surface of the connector 312 is provided with a recessed groove, such as a rectangular groove, and the pressing block 311 is embedded in the recessed groove and fixed by glue or screws to achieve precise positioning and firm connection between the two.

[0070] In the locked state, the assembly surface portion of the connector 312 (located outside the pressing block 311) contacts the inner bottom surface of the mounting housing 100, thereby limiting the reset stroke of the pressing assembly 310 and preventing the pressing assembly 310 from dislodging from the mounting hole 103 under the action of the reset spring 321.

[0071] Of course, in addition to the above-mentioned method of constructing a recessed groove on the mounting surface of the connector 312, a stop block can also be provided below the mounting housing 100 on the side of the mounting hole 103. The stop block extends a certain distance along the second direction (Y direction) so that in the locked state, the area of ​​the connector 312 located outside the pressing block 311 can abut against the stop block, thereby limiting the reset stroke of the pressing assembly 310 and preventing the pressing assembly 310 from dislodging from the mounting hole 103 under the action of the reset spring 321.

[0072] In this embodiment, the setting of the sinking groove can ensure the assembly accuracy of the pressing block 311 and the connecting piece 312 and avoid relative misalignment between the two; the retaining edge structure of the connecting piece 312 can achieve the anti-disengagement function without additional limiting parts, which simplifies the structure and improves the stability in the locked state.

[0073] It should be noted that the stop plate 110 has a pre-set limit post 322. During installation, the return spring 321 is sleeved on the limit post 322, and then the separate pressing block 311 and connecting piece 312 are respectively sleeved on the limit post 322. Subsequently, the pressing block 311 and connecting piece 312 are fastened together with bolts. Since the size of the connecting piece 312 is larger than the size of the mounting hole 103, it can limit the pressing block 311 to prevent it from coming out of the mounting hole 103. As can be seen from the above assembly process, the quick-release structure provided in this embodiment has a simple structure, few parts, and does not require special fixtures during the entire installation process, which can significantly improve assembly efficiency.

[0074] In some embodiments, the side of the pressing block 311 facing the reset assembly 320 is provided with a clearance groove (not shown), at least a portion of the reset assembly 320 passes through the clearance groove, and the clearance groove is configured to provide clearance space for relative movement of the pressing block 311 and the reset assembly 320 in a second direction (Y direction).

[0075] It is understood that the pressing block 311 has a clearance groove on the side facing the reset assembly 320. This clearance groove can be a rectangular or circular groove, which can be set according to the shape of the limiting post 322, and is not limited here. Part of the structure of the reset assembly 320 (mainly the end of the limiting post 322) passes through the clearance groove. When the pressing block 311 moves along the second direction (Y direction) (towards the inside of the mounting hole 103), the reset assembly 320 is compressed, and the part of the limiting post 322 that extends into the clearance groove can further enter the groove with the movement of the pressing block 311, avoiding interference with the pressing block 311.

[0076] In this embodiment, the setting of the relief groove can increase the movement stroke of the pressing component 310 without increasing the overall size of the mounting hole 103, ensuring that when the pressing block 311 is pressed, the second positioning component 3121 can completely disengage from the first positioning component 210; at the same time, the compact space design meets the needs of lightweight and miniaturization of portable devices.

[0077] In one example, the second direction (Y direction) is perpendicular to the first direction (X direction). Specifically, the first direction (X direction) is the sliding direction of the cover 200, which can be horizontal, and the second direction (Y direction) is the movement direction of the pressing component 310, which can be vertical. The two are perpendicular to each other. Specifically, the cover 200 slides horizontally to open or close the opening 104, and the pressing component 310 is pressed vertically to unlock.

[0078] In one example, the first positioning component 210 and the second positioning component 3121 are mutually adaptable and interlocking concave-convex structures. In this embodiment, the interlocking of the first positioning component 210 and the second positioning component 3121 includes at least two methods:

[0079] Option 1, such as Figure 3 As shown, Figure 3 This is a schematic diagram of the quick-release structure for removing the cover plate according to some embodiments of this application. In some embodiments, the first positioning component 210 is a mating hole constructed at one end of the cover 200, and the second positioning component 3121 is a limiting block disposed at one end of the connector 312; in the locked state, the limiting block is adapted to engage in the mating hole. Specifically, the closed end of the cover 200 along the first direction (X direction) is provided with a mating hole, such as a rectangular hole, and the end of the connector 312 is provided with a limiting block adapted to the shape of the mating hole, such as a rectangular protrusion. In the locked state, the limiting block is engaged in the mating hole under the action of the return spring 321, restricting the cover 200 from sliding along the first direction (X direction); when unlocked, the pressing component 310 drives the limiting block to disengage from the mating hole along the second direction (Y direction), and the cover 200 can slide freely.

[0080] In one example of the second scheme, the first positioning component 210 is a limiting block located at one end of the cover 200, and the second positioning component 3121 is a mating hole constructed at one end of the connector 312. In the locked state, the limiting block is fitted into the mating hole. Specifically, the closed end of the cover 200 is provided with a limiting block, such as a wedge-shaped protrusion, and the end of the connector 312 is provided with a mating hole, such as a wedge-shaped hole, that matches the limiting block. In the locked state, the limiting block is engaged in the mating hole; when unlocked, the pressing component 310 moves the mating hole along the second direction (Y direction), releasing the limiting block.

[0081] Of course, regardless of the above scheme, a reliable snap-fit ​​is achieved through the interlocking of concave and convex parts. The structure is simple and the locking strength is high. The specific scheme can be flexibly selected according to the structural space of the cover 200 and the connector 312, thereby improving the design flexibility.

[0082] like Figure 2 As shown, in some embodiments, the limiting block has a guide surface 3122 on the side facing the cover 200. The guide surface 3122 is configured to move the connector 312 away from the mounting surface 102 under the push of the cover 200, so that the limiting block engages with the mating hole.

[0083] It is understood that the side of the limiting block facing the cover 200, that is, the side that first contacts the cover 200 when it is closed, is provided with an inclined guide surface 3122. This guide surface 3122 can be an inclined surface or an arc surface. When the cover 200 slides to the closed position along the first direction (X direction), the first positioning component 210 of the cover 200 contacts the guide surface 3122. The inclined component of the guide surface 3122 pushes the limiting block to move along the second direction (Y direction) (away from the mounting surface 102). At this time, the return spring 321 is compressed. When the cover 200 is fully closed and the mating hole is aligned with the limiting block, the elastic force of the return spring 321 drives the limiting block to reset and lock into the mating hole.

[0084] In this embodiment, the first positioning component 210 and the second positioning component 3121 can be engaged by simply pushing the cover plate 200 to move continuously toward the guide surface 3122 with external force. During this process, there is no need to apply external force (manually) to the pressing component 310. Therefore, the setting of the guide surface 3122 in this embodiment realizes the automatic locking of the cover 200. The closing and locking can be completed without manually pressing the unlocking mechanism, which simplifies the operation steps and is especially suitable for scenarios where batteries or consumables are frequently replaced, thus improving the user experience.

[0085] like Figure 3 As shown, in one example, the cover 200 has an extension 220 at one end along a first direction (X direction), and a mating hole is formed in the extension 220.

[0086] Specifically, the cover 200 extends a portion 220 from its closed end along the first direction (X direction), and a mating hole is formed on the portion 220. The length of the portion 220 can be adjusted according to the position of the locking mechanism 300 to ensure that the mating hole can be precisely aligned with the second positioning component 3121.

[0087] In this embodiment, the extension 220 provides an independent space for the mating hole, avoiding the impact of opening holes on the main body of the cover 200 on the structural strength; at the same time, the extension 220 can increase the contact area between the first positioning component 210 and the second positioning component 3121, and improve the snap-fit ​​stability.

[0088] like Figure 1 As shown, in one example, the mounting housing 100 has a baffle 120 connecting the opening 104 and the mounting hole 103, and at least a portion of the cover plate with a mating hole extends into the space inside the baffle 120 to limit the cover plate in a second direction (Y direction) by the baffle 120.

[0089] Understandably, one end of the baffle 120 is connected to the edge of the opening 104, and the other end extends to the mounting hole 103. There is a limiting space below the baffle 120. When the cover 200 is closed, its extension 220 with the mating hole extends into the space inside the baffle 120, and the inner wall of the baffle 120 is clearance-fitted with the side of the extension 220.

[0090] In this embodiment, the baffle 120 restricts the displacement of the cover 200 (especially the extension 220) along the second direction (Y direction), preventing the cover 200 from shifting along the second direction (Y direction) during vibration or accidental collision, thereby avoiding loosening or disengagement of the first positioning component 210 and the second positioning component 3121, and further improving the locking reliability. At the same time, the baffle 120 can also provide lateral guidance for the sliding of the cover 200, ensuring that the cover 200 moves smoothly along the first direction (X direction).

[0091] Based on the same concept, this application also provides a medical device that includes the quick-release structure described in the above embodiments.

[0092] It is understood that the medical device in this embodiment may be a portable ultrasound diagnostic instrument, infusion pump, blood glucose meter, etc., integrating a quick-release structure. The device includes a main unit (mounting housing 100), functional modules, a cover 200, and a quick-release structure. The mounting housing 100 has a receiving cavity 101 and an opening 104. The receiving cavity 101 can accommodate a battery or other functional modules. The cover 200 slides open and close along a first direction (X direction). The locking mechanism 300 of the quick-release structure includes the pressing component 310 and the reset component 320 in the above embodiment.

[0093] In the ultrasound diagnostic instrument, when the cover 200 slides closed, the mating hole and the limiting block engage and lock; pressing unlocks the cover 200, allowing it to slide open for battery replacement. The quick-release structure of infusion pumps and blood glucose meters is similar, offering convenient operation. This structure requires no tools, improving efficiency while maintaining lightweight design and reliability, thus reducing costs. The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described; however, as long as these combinations of technical features do not contradict each other, they should be considered within the scope of this specification.

[0094] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
