Description

Technical Field

[0001] This invention relates to the field of AED devices, and more specifically to structures related to the battery cells of AED devices. Background Technology

[0002] In recent years, the marketing model for AEDs has gradually expanded to the home, enterprise, and public markets. However, due to power supply issues, batteries are sometimes not installed at the factory and must be installed by the user before use. Installing the battery requires opening the battery compartment cover on the outer casing, inserting the battery, and then reinstalling the cover to secure it to the main body of the casing.

[0003] While screws secure the battery compartment cover to the main body, providing a reliable connection, they require tools, significantly increasing installation costs for service personnel. In consumer electronics and everyday products, such as remote controls, some battery compartment covers feature screwless designs, allowing for easy manual assembly and disassembly. However, in the medical device field, in addition to ease of disassembly and assembly, the reliability of the assembly structure between the cover and the main body must be considered to ensure the battery remains securely in place and withstand unexpected or emergency situations. Summary of the Invention

[0004] The main technical problem solved by this invention is how to improve the reliability of the assembly structure between the battery compartment cover and the outer shell in medical devices.

[0005] One embodiment provides an AED device.

[0006] AED devices include:

[0007] The shell body has a battery compartment for inserting battery cells and has an installation port for inserting and removing battery cells.

[0008] The device includes an interface unit, an energy storage capacitor, and a circuit board unit. The interface unit forms a connection portion on the housing body for connecting to the treatment electrode to deliver electrical energy to the treatment electrode. The energy storage capacitor and the circuit board unit are disposed inside the housing body. The energy storage capacitor is used to store electrical energy for defibrillation. The circuit board unit is connected to the treatment interface and the energy storage capacitor to control the operation of the AED device.

[0009] and a cover, the cover being used to seal the mounting port;

[0010] The cover and the shell body are provided with a mutually adaptable snap-fit ​​structure, which is used to detachably fix the cover to the shell body; the cover has an inner inner surface, which is opposite to the mounting opening along the orientation of the mounting opening, and a protrusion is provided on the inner surface of the cover. The protrusion forms a support surface on the edge of the corresponding side of the cover, and the support surface and the edge of the corresponding side of the cover are spaced apart in a direction perpendicular to the support surface; the shell body is provided with a bearing surface. When the cover is installed in place, the bearing surface and the support surface are arranged opposite to each other to position the cover in a direction perpendicular to the support surface.

[0011] Another AED device is provided in one embodiment.

[0012] AED devices include:

[0013] The shell body has a battery compartment for inserting battery cells and has an installation port for inserting and removing battery cells.

[0014] The device includes an interface unit, an energy storage capacitor, and a circuit board unit. The interface unit forms a connection portion on the housing body for connecting to the treatment electrode to deliver electrical energy to the treatment electrode. The energy storage capacitor and the circuit board unit are disposed inside the housing body. The energy storage capacitor is used to store electrical energy for defibrillation. The circuit board unit is connected to the treatment interface and the energy storage capacitor to control the operation of the AED device.

[0015] At least two types of battery cells, the different battery cells having different capacities, housing shapes and / or housing sizes, the battery compartment having a positioning structure for adapting any one of the battery cells into the battery compartment;

[0016] And a cover, the cover being used to seal the mounting port.

[0017] The beneficial effects of this invention are:

[0018] According to the medical device housing in the embodiments of this application, the snap-fit ​​structure enables the detachable fixing of the cover and the housing body, facilitating disassembly and assembly. At the same time, by providing a protrusion on the inner side of the cover, the protrusion forms a support surface on the corresponding side of the cover. The support surface can be arranged opposite to the bearing surface on the housing body. When the cover is subjected to external impact, such as when the medical device falls and the corresponding side of the cover perpendicular to the support surface lands on the ground, the bearing surface can support the support surface, preventing the cover from being deformed and damaged due to excessive force, thereby improving the reliability of the assembly structure between the cover and the housing.

[0065] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments. Similar elements in different embodiments are referred to by related similar element reference numerals. In the following embodiments, many details are described to facilitate a better understanding of the present application. However, those skilled in the art will readily recognize that some features may be omitted in different situations, or may be replaced by other elements, materials, or methods. In some cases, certain operations related to the present application are not shown or described in the specification. This is to avoid obscuring the core parts of the present application with excessive description. For those skilled in the art, detailed description of these related operations is not necessary; they can fully understand the related operations based on the description in the specification and general technical knowledge in the art.

[0066] Furthermore, the features, operations, or characteristics described in the specification can be combined in any suitable manner to form various embodiments. At the same time, the steps or actions in the method description can be rearranged or adjusted in a manner obvious to those skilled in the art. Therefore, the various orders in the specification and drawings are only for the clear description of a particular embodiment and do not imply a necessary order, unless otherwise stated that a particular order must be followed.

[0067] The serial numbers assigned to components in this document, such as "first" and "second," are used only to distinguish the described objects and have no sequential or technical meaning. The terms "connection" and "linkage" used in this application, unless otherwise specified, include both direct and indirect connections (linkages).

[0068] An AED (Automated External Defibrillator) is a portable, automated defibrillator suitable for use by non-professionals, typically used in public places, ambulances, and home emergency situations. An AED restores a normal heart rhythm by delivering an electric shock to the heart. In the event of cardiac arrest, defibrillation and CPR using an AED within the crucial "golden four minutes" are effective ways to prevent sudden cardiac arrest.

[0069] In some embodiments, the AED device includes a main unit 100 and a battery unit 300. The main unit 100 includes a housing 110 and functional modules disposed within the housing 110. The housing 110 has a battery compartment 114 for housing the battery unit 300, and the battery compartment 114 has an installation port 1141 for inserting and removing the battery unit 300. The functional modules may include an interface unit, an energy storage capacitor, and a circuit board unit. The interface unit forms a connection portion on the housing 110 for connecting to a treatment electrode to deliver electrical energy to the treatment electrode. The energy storage capacitor and the circuit board unit are disposed within the housing 110. The energy storage capacitor stores electrical energy for defibrillation, and the circuit board unit is connected to the treatment interface and the energy storage capacitor to control the operation of the AED device.

[0070] In one embodiment, the shell body 110 may include a first shell 111 and a second shell 112, the first shell 111 and the second shell 112 together form a shell cavity, and corresponding functional modules may be installed in the shell cavity.

[0071] In one embodiment, the circuit board unit may include a main control board, a treatment board, etc., and the treatment board may include a charging circuit and a discharging circuit. When the AED device detects the need for defibrillation, it can store electrical energy from the battery unit 300 in an energy storage capacitor through the charging circuit. After the energy storage capacitor is fully charged, the AED device can release this electrical energy to the patient's chest through electrodes to deliver an electric shock. Discharge energy is an important indicator of an AED device. Because the AED device needs to provide a high-energy defibrillation current to the patient, a large energy storage capacitor is required to store the energy for the electric shock and provide this high-energy electric shock when needed. For this reason, the energy storage capacitor in an automated external defibrillator usually has a large volume. The common shape of the energy storage capacitor is cylindrical, and the diameter of the energy storage capacitor often determines the maximum thickness of the AED device.

[0072] The interface unit can be fixed to the circuit board unit and connected to the corresponding circuit, or fixed to the housing and connected to the corresponding circuit on the circuit board unit via a cable. A dust cover can be provided on the connection portion formed on the housing body 110 of the interface unit. In use, the dust cover can be opened to connect the treatment electrode to the connection portion.

[0073] Please refer to Figure 1 and Figure 2 In one embodiment, the second housing 112 may have a protruding portion 1121, which can form a corresponding chamber within the housing cavity. The radial and axial dimensions of the energy storage capacitor are adapted to the protruding portion 1121, and one radial side of the energy storage capacitor can be disposed within the chamber formed by the protruding portion 1121. This compact structure facilitates the miniaturization of the housing body 110. When using the AED device, the second housing 112 can be supported on a placement platform for carrying the AED device, and the protruding portion 1121 can also serve to support the AED device.

[0074] It should be noted that the above structures are merely illustrative of some possible structures that an AED device may employ, in order to provide readers unfamiliar with AED devices with some understanding. Those skilled in the art will understand that this application does not limit the overall outline of the main body 110, nor does it limit the number or parameters of functional modules. Except for the structures related to the battery unit 300, battery compartment 114, and compartment cover 200, the specific structures of other parts of the AED device can refer to existing structures in related technologies. Considering that these structures are not directly related to the innovative content and technical problems to be solved in this application, they will not be described in detail here.

[0075] Due to the special application scenarios of AED devices, their reliability must be considered during manufacturing. For example, in order to facilitate manual disassembly and assembly, when the cover 200 used to seal the battery compartment 114 on the AED is designed as a screwless structure, the reliability of the assembly structure between the cover 200 and the main body 110 needs to be considered to prevent the cover 200 from easily falling off, and even to prevent the cover 200 from falling off when the AED device is dropped.

[0076] In the embodiments of this application, while the AED device's compartment cover 200 is assembled using a snap-fit ​​structure, a protrusion 216 is provided on the inner side of the cover 200. The protrusion 216 forms a support surface 2165 at the edge of the compartment cover 200. The support surface 2165 can abut against the bearing surface 1131 on the shell body 110, thereby positioning the compartment cover 200 in a direction perpendicular to the support surface 2165. The protrusion 216 improves the structural stability of the compartment cover 200.

[0077] In some embodiments, the AED device also employs a battery compatibility design, allowing the same main unit 100 structure to adapt to different battery specifications, thereby meeting various usage requirements. By providing a sealing structure at the conductive interface between the battery unit 300 and the main unit 100, the waterproof performance of the AED device can be improved; by providing a limiting member 343 inside the battery casing 320, the positioning reliability of the internal components of the battery unit 300 can be improved.

[0078] The present invention will now be further described with reference to some specific embodiments.

[0079] To more clearly illustrate the specific embodiments of the present invention, the following will use the term... Figure 1 and Figure 2 The directions shown are described as up, down, left, right, front, and back. Of course, this orientation limitation in the embodiment is only to illustrate the positional relationship between the various components more clearly, and does not limit the embodiments of the present invention to be arranged in this way.

[0080] Please refer to Figure 1 and Figure 2 The battery compartment 114 on the main body 110 can be formed by a recess on the second housing 112, with an opening forming a mounting port 1141 for inserting and removing the battery unit 300. The mounting port 1141 can be rectangular to match the shape of the battery unit 300. After the battery unit 300 is installed in the battery compartment 114, the host connector 310 at the left end of the battery unit 300 can be connected to the battery connector 130 on the left side of the battery compartment 114 to connect the battery unit 300 to the main control board and supply power to the functional modules.

[0081] The compartment cover 200 is used to cover the mounting port 1141. The compartment cover 200 can be disassembled at the parting line of the main unit 100, which helps to ensure the integrity of the appearance. To facilitate user disassembly and assembly of the compartment cover 200, a mutually adaptable snap-fit ​​structure is provided between the compartment cover 200 and the shell body 110. The snap-fit ​​structure is used to detachably fix the compartment cover 200 to the shell body 110. The snap-fit ​​structure between the compartment cover 200 and the shell body 110 can adopt common structures, such as sliding snap-fit, snap-fit ​​along the vertical direction, or one side of the compartment cover 200 is hinged while the opposite side is snapped in a swinging manner.

[0082] In one embodiment, please refer to Figure 6 and Figure 7 The cover 200 is slidably mounted on the shell body 110. The sliding direction of the cover 200 is a first direction, and the plane containing the mounting opening 1141 has a second direction perpendicular to the first direction. Figure 6 and Figure 7(Not shown in the figure, but in a direction perpendicular to the paper), the opening direction of the mounting port 1141 is a third direction.

[0083] Please refer to Figure 3 , Figure 4 , Figure 5 The compartment cover 200 includes a main body 210, a limiting flange 211, and a tail flange 212. The main body 210 has a first side and a second side along the first direction, namely a front side and a rear side. The first side corresponds to the sliding direction of the compartment cover 200 during installation, and the second side corresponds to the sliding direction of the compartment cover 200 during disassembly. The tail flange 212 is located on the rear side of the main body 210, and the limiting flange 211 connects the left and right sides of the main body 210. Viewed along the first direction, the outer surface of the limiting flange 211 can be a concave curved surface.

[0084] The snap-fit ​​structure includes snap-fit ​​ear plates disposed on both sides of the compartment cover 200 along the first direction, the snap-fit ​​ear plates extending along the first direction toward the installation direction of the compartment cover 200. In one specific embodiment, the compartment cover 200 has five snap-fit ​​ear plates on the front side and seven snap-fit ​​ear plates on the rear side.

[0085] In some embodiments, at least one of the snap-fit ​​lugs is used to connect with a snap-fit ​​2151 on the shell body 110 to restrict the compartment cover 200 from moving in a direction opposite to the installation direction. At least one of the snap-fit ​​lugs has a limiting plane 2154 on the side connected to the shell body 110, which abuts against a limiting mating portion on the shell body 110 to restrict the compartment cover 200 from moving away from the shell body 110 along the opening direction of the mounting port 1141. In one specific embodiment, the five snap-fit ​​lugs on the front side include two snap-fit ​​2151 for connecting with the shell body 110, and three limiting buckles 2153 for preventing a step difference between the compartment cover 200 and the shell body 110 along a third direction, with the limiting plane 2154 provided on the limiting buckles 2153. The seven latching lugs on the rear side include three latches 2151 for connecting with the shell body 110 to form a latch 2151, and four limiting latches 2153 for preventing a step difference from forming between the cover 200 and the shell body 110 in a third direction. The limiting latches 2153 are provided with the aforementioned limiting plane 2154. In some other embodiments, the number of latches 2151 and latching lugs can be increased or decreased, and the latches 2151 can also be provided only on the front or rear side of the cover 200.

[0086] Those skilled in the art should understand that the snap fastener 2151 includes a snap-fit ​​protrusion, which can snap into a suitable slot or stepped structure, thereby preventing the snap fastener 2151 from easily disengaging in the opposite direction. A step difference refers to the height difference between two adjacent parts on the surface of an object. When the step difference is large, a step will form on the surface of the object, affecting its appearance and making it easy to scratch. For example... Figure 9 and Figure 10 The aforementioned snap-fit ​​ear plates on the front and rear sides of the cover 200 not only prevent the cover 200 from coming off when it is installed, but also control the step difference between the front side of the cover 200 and the shell body 110, as well as the gap between the rear side of the cover 200 and the shell body 110.

[0087] In this application, when installing the 200mm cover, please refer to... Figure 7 First, install the cover 200 vertically until it is flush with the mounting opening 1141 on the battery compartment 114. Then, push it horizontally from back to front until the clip 2151 engages, and it will be installed in place. For disassembly, please refer to [the instructions]. Figure 6 First, push the compartment cover 200 horizontally from front to back until the latch 2151 disengages, then remove the compartment cover 200 upwards to achieve a screwless design. The latch 2151 works by using a guide slope 2152 on the latching protrusion to deflect the latch 2151 when the compartment cover 200 is moved horizontally. This causes the corresponding latching lug to bend elastically, pushing the compartment cover 200 forward or backward to engage or disengage with the main unit 100. Both the main unit 100 and the compartment cover 200 have guide structures on their left and right sides. The compartment cover 200 can only move forward and backward along these guide structures to engage and disengage, facilitating the installation and removal of the battery unit 300.

[0088] In one embodiment, the guide slopes 2152 on the front and rear sides of the buckle 2151 have different angles with the plane containing the mounting opening 1141, specifically as follows: when the cover 200 is inserted, if... Figure 8 The angle between the guide slope 2152 on the front side and the plane containing the mounting port 1141 is 20° (in some other embodiments, it may be other values ​​less than 30°), and its component force along the third direction is large, making the snap-fit ​​ear plates easier to deform and easier to complete the interlocking; such as Figure 9 When the cover 200 is disassembled, the angle between the rear guide slope 2152 and the plane containing the mounting opening 1141 is 80° (in some other embodiments, it may be a value greater than 70°). Its component force along the third direction is very small, making the fastener less prone to elastic deformation and difficult to detach. Thus, when the customer assembles or disassembles the cover 200, it is easier for the user to install it, and once installed correctly, the cover is not easily detached.

[0089] It should be noted that the snap-fit ​​ear plate can be a flat plate with a planar structure, or it can have stiffeners arranged perpendicular to the flat plate. The stiffeners can improve the structural strength of the snap-fit ​​ear plate. In addition, in some other embodiments, the main body 210 of the cover 200 can also be a flat plate structure, or only the aforementioned limiting fold 211 can be provided, or only the aforementioned tail fold 212 can be provided.

[0090] The shell body 110 is provided with matching limiting portions 115 on both sides along the second direction. The limiting flange 211 abuts against the limiting portion along the second direction to position the compartment cover 200 and guides the sliding of the compartment cover 200. In some other embodiments, the guiding of the compartment cover 200 can also be achieved by other structures. For example, a guide groove can be provided on the shell body 110, and the limiting flange 211 can be inserted into the guide groove to guide the compartment cover 200.

[0091] The cover 200 has an inner inner surface, which faces the mounting opening 1141 along its orientation. A protrusion 216 is provided on the inner inner surface, forming a support surface 2165 on the edge of the corresponding side of the cover 200. The support surface 2165 and the edge of the corresponding side of the cover 200 are spaced apart in a direction perpendicular to the support surface 2165. The shell body 110 has a bearing surface 1131. When the cover 200 is installed in place, the bearing surface 1131 and the support surface 2165 are arranged opposite each other to position the cover 200 in a direction perpendicular to the support surface 2165.

[0092] In some embodiments, the cover 200 includes a support rib protruding from the inner side of the cover body. The support rib includes a first rib 2161 and a second rib 2163 perpendicular to the first rib 2161. At least a portion of the support surface 2165 is formed by the end face of the first rib 2161, and / or, at least a portion of the support surface 2165 is formed by the surface of the second rib 2163. The first rib 2161 is perpendicular to a first direction, and the second rib 2163 is perpendicular to a second direction.

[0093] In one embodiment, the hopper cover 200 is provided with the first stiffening plate 2161 and the second stiffening plate 2163 on each side along the second direction, which can better strengthen the structure. On the left side of the hopper cover 200, the support surface 2165 is formed by the surface of the second stiffening plate 2163. On the right side of the hopper cover 200, the support surface 2165 is formed by the end face of the first stiffening plate 2161. In a specific embodiment, please refer to... Figure 12 and Figure 13The first stiffener 2161 has an L-shaped step 2162, and the supporting surface 2165 is formed by the corresponding step surface of the L-shaped step 2162, which can form a high supporting strength. In one specific embodiment, the first stiffener 2161 can be cut off at the supporting surface 2165, and the supporting surface 2165 can be formed by the entire end face of the corresponding side of the first stiffener 2161. Since the supporting force of a single stiffener is limited, in some embodiments, a reinforcing rib 2164 can be provided between at least one side of the second stiffener 2163 and the inner side of the cover, and the reinforcing rib 2164 is perpendicular to the second stiffener 2163, thereby strengthening the second stiffener 2163. Of course, in some other embodiments, a reinforcing rib 2164 can also be provided between the side of the first stiffener 2161 and the inner side of the cover.

[0094] To better ensure the structural strength and stress stability of the silo cover 200, at least two first stiffening plates 2161 can be arranged at intervals along the thickness direction of the first stiffening plate 2161 and simultaneously connected with at least one second stiffening plate 2163 to form intersecting stiffening plates, which can reinforce each other.

[0095] Those skilled in the art will understand that in some other embodiments, the protrusion 216 on the inner surface of the lid 200 can be replaced with other forms, such as a bump. Furthermore, the support surface 2165 formed by the protrusion 216 can be two locations arranged opposite each other along the second direction; correspondingly, two bearing surfaces 1131 can be provided on the shell body 110. Additionally, the protrusion 216 can occupy the middle portion of the inner surface of the lid, with one protrusion 216 forming a bearing surface 1131 on each side of the inner surface of the lid in the second direction.

[0096] In some embodiments, please refer to Figure 2 The housing body 110 includes a support plate 113 located around the mounting opening 1141, and the support surface 1131 is formed by the surface of the support plate 113. The support plate 113 may be part of a side plate used to form the battery compartment 114.

[0097] In one embodiment, please refer to Figure 4 At least one of the first stiffening plates 2161 is provided with a slot, the slot having lateral groove walls arranged opposite each other along the second direction. When the cover 200 is installed in place, the support plate 113 is embedded in the slot to form a positioning along the second direction. The slot allows the cover 200 to be bidirectionally positioned along the second direction by the support plate 113, which is more conducive to ensuring structural strength.

[0098] In one embodiment, please refer to Figure 13When the cover 200 is installed in place, the side of the bearing plate 113 away from the shell body 110 is supported on the support rib, so that the cover 200 can have better assembly stability.

[0099] When the cover 200 is large, gaps may appear between the left and right sides of the cover 200 and the shell body 110 due to deformation of the cover 200. To improve this problem, in one embodiment, the first stiffening plate 2161 is provided with a limiting ear plate 2166, which extends along the first direction toward the installation direction of the cover 200. The shell body 110 is provided with a snap-fit ​​part 119. When the cover 200 is installed in place, the snap-fit ​​part 119 is used to block the limiting ear plate 2166 along the third direction, so as to limit the cover 200 from moving away from the shell body 110 along the third direction. Figure 6 The aforementioned snap-fit ​​portion 119 can be located on the outer side of the support plate 113 in the left or right direction. The front and rear positions of the aforementioned limiting ear plate 2166 on the compartment cover 200 can be adjusted as needed.

[0100] Please refer to Figure 4 , Figure 13 , Figure 14 and Figure 15 In some embodiments, the inner side of the cover 200 is also provided with a limiting rib 2167. The limiting rib 2167 can be provided at the front end of the left and right sides of the cover 200. The limiting rib 2167 can abut against the bearing plate 113 around the mounting port 1141 in the left and right direction to position the cover 200 in the left and right direction and avoid the difference between the left and right sides of the cover 200 and the shell body 110.

[0101] If an AED device falls or collides with other objects, the rear end of the cover 200 may bear the force first. To address this, in one embodiment, the tail flange 212 is provided with a tail support protrusion 217. This protrusion 217 protrudes towards the first side. When the cover 200 is installed, the tail support protrusion 217 supports the housing body 110 along the opening direction of the mounting port 1141, thus preventing the cover 200 from moving away from the housing body 110 along the opening direction of the mounting port 1141. The tail support protrusion 217 can also be formed by a rib and can be connected to the rib corresponding to the snap-fit ​​ear plate with the limiting plane 2154. Those skilled in the art will understand that in some other embodiments, the tail support protrusion 217 can also be in other forms, such as a bump.

[0102] The cover 200 has an outer surface facing opposite to the inner surface of the cover. When the AED device is placed with the second housing 112 below, a foot pad 213 can be provided on the outer surface of the cover. The foot pad 213 protrudes from the outer surface of the cover and is used to support the device on the placement platform. Because the foot pad 213 forms a protrusion 216 on the cover 200, the part of the cover 200 corresponding to the foot pad 213 is more susceptible to deformation under external forces, which in turn affects the reliability of the connection between the cover 200 and the housing body 110. Therefore, in one embodiment, an interlaced rib plate 214 is provided on the inner surface of the cover. The interlaced rib plate 214 corresponds to the foot pad 213 along the inner and outer sides of the cover 200, which can strengthen the structural strength of the cover 200 at the position corresponding to the foot pad 213.

[0103] In addition, when pushing the lid 200 forward or backward, anti-slip textures can be provided on the outer surface of the lid to facilitate pushing it. The anti-slip textures form a raised and recessed structure, which can increase friction. The anti-slip textures can be distributed near the two latches 2151 on the front side of the lid 200. When pushing the anti-slip textures, pressing further increases the force that deforms the latching lugs, making it easier for the latches to disengage and the lid 200 to be disassembled by hand.

[0104] The aforementioned compartment cover 200 can also be snapped into the housing body 110 in other ways. For example, in some embodiments, the compartment cover 200 includes a movable hook 2181, and the housing body 110 is provided with an adapter locking part 116; the movable latch 2151 has a locking position and an unlocking position. When the movable latch 2151 is in the locking position, it engages with the adapter locking part 116 to restrict the compartment cover 200 from moving away from the housing body 110 along the direction of the mounting opening 1141; when the movable latch 2151 is in the unlocking position, it separates from the adapter locking part 116 to release the snap-fit ​​relationship; an elastic reset member 2182 is provided between the movable latch 2151 and the compartment cover 200, and the elastic reset member 2182 is used to apply an elastic force to the movable latch 2151 to move towards the locking position. The specific form of the above-mentioned elastic reset member 2182 is not limited, for example, it can be a compression spring, a tension spring, an elastic cantilever, etc.

[0105] Please refer to Figure 16The movable hook 2181 can be movably positioned along the second direction. In one specific embodiment, the contact surface between the movable hook 2181 and the adapter locking part 116 is parallel to the plane where the mounting opening 1141 of the battery compartment 114 is located, which can achieve a better locking effect and make it less likely that the hook will unlock when the compartment cover 200 is subjected to external force, unless the movable hook 2181 is actively moved to the unlocked position. The aforementioned movable hook 2181 can be provided on both sides of the left and right directions of the compartment cover 200, or the aforementioned movable hook 2181 can be provided on one side of the left and right directions of the compartment cover 200, and the opposite side abuts against the groove wall provided on the shell body 110 / hinged to the shell body 110 along the left and right directions. Please refer to Figure 17 The active hook 2181 can also be set to move along the first direction.

[0106] In one embodiment, please refer to Figure 18 The inner side of the cover is provided with a straight arm buckle 2183, which is perpendicular to the inner side of the cover. The shell body 110 is provided with a straight arm slot 117 for inserting the straight arm buckle 2183. The straight arm slot 117 extends in a direction parallel to the mounting opening 1141. The straight arm buckle 2183 is provided with a snap-fit ​​protrusion, and the side wall of the straight arm slot 117 is provided with a limiting groove. The snap-fit ​​protrusion is used to snap into the limiting groove to limit the cover 200 from moving away from the shell body 110 along the opening direction of the mounting opening 1141. When installing the cover 200, the buckle can be engaged with the buckle on the main unit 100 by the deformation of the straight arm. When disassembling, the straight arm buckle 2183 is deformed and disengaged by applying a force perpendicular to the outer side of the cover 200.

[0107] Additionally, in one embodiment, please refer to Figure 19 The cover 200 can also be equipped with a U-shaped buckle 2184. The side of the U-shaped buckle 2184 away from the cover 200 can swing elastically, thereby realizing the movement of the locking protrusion and meeting the installation and disassembly requirements.

[0108] Depending on different power requirements and cost factors, users may require different battery units 300. In one embodiment, the AED device includes at least two types of battery units 300, each with different capacities, housing shapes, and / or housing dimensions. The battery compartment 114 is provided with a positioning structure for adapting any one of the battery units 300 inserted into the battery compartment 114. Please refer to... Figure 2In some embodiments, the positioning structure on the battery compartment 114 can be a positioning protrusion 1181 on the side wall of the battery compartment 114, and the battery unit 300 is provided with a corresponding L-shaped slot 311. When installing the battery unit 300, the battery unit 300 is placed into the battery compartment 114 along a third direction, so that the positioning protrusion 1181 enters the upper and lower extensions of the L-shaped slot 311. Then, the battery unit 300 is pushed to the left so that the left and right extensions of the L-shaped slot 311 are adapted to the positioning protrusion 1181. The upper and lower side walls of the left and right extensions can be used to limit the battery unit 300, preventing the battery unit 300 from moving away from the housing body 110 along the opening direction of the mounting port 1141.

[0109] The AED device includes a battery connector 130 for connection to the host connector 310 on the battery unit 300, and the battery connector 130 is disposed within the housing body 110. When the battery unit 300 is installed, the battery connector 130 is electrically connected to the host connector 310, enabling the transmission of electrical energy. The specific structure of the battery connector 130 connected to the host connector 310 is not limited, and existing structures in related technologies can be referenced, as long as the corresponding circuit is made conductive during the installation of the battery unit 300.

[0110] Please refer to Figure 20 and Figure 21 In one embodiment, the battery cell 300 may be a thinner battery cell 300 (dimension along a third direction), or it may be as follows: Figure 22 and 23 The battery cell 300 shown is thicker. For a thinner battery cell 300, the cover 200 can be... Figure 1 , Figure 2 The shown is the compartment cover 200; for thicker battery cells 300, the compartment cover 200 can be adopted... Figure 24 The shown is a 200mm bin cover. Figure 24 The shown compartment cover 200 and Figure 1 , Figure 2 The main difference of the shown compartment cover 200 lies in the size of the limiting fold 211 and the tail fold 212, and it is also provided with a front fold 2185. The compartment cover 200 can still be provided with corresponding limiting ear plates 2166 and protrusions 216.

[0111] In order to limit the position of the battery cell 300, in one embodiment, please refer to Figure 25The battery compartment 114 has a first sidewall, and the battery connector 130 is disposed on the first sidewall; the battery compartment 114 also has a second sidewall facing the first sidewall, a third sidewall and a fourth sidewall connected between the first sidewall and the second sidewall; the first sidewall is provided with an anti-collision protrusion 1182, which is used to limit the movement distance of the battery unit 300 toward the battery connector 130, and can prevent the battery unit 300 from hitting the battery connector 130.

[0112] Meanwhile, positioning protrusions may be provided on the third and fourth sidewalls. These protrusions are used to position the battery unit 300 along the spacing direction of the third and fourth sidewalls, so that the host connector 310 on the battery unit 300 is aligned with the battery connector 130. The positioning protrusions also serve as anti-collision features. If the battery unit 300 is offset in the front-to-back direction, the battery connector 130 will not be able to accurately align with the host connector 310. The male connectors on both will not be able to connect with the female connector on the other, and may instead collide with the male connector on the other.

[0113] Please refer to Figure 26 , Figure 27 , Figure 28 To accommodate the replacement needs of the battery unit 300, in one embodiment, the battery compartment 114 has a clearance opening 120 on its wall, which exposes the battery connector 130. The AED device includes a clearance opening sealing gasket 121, which surrounds the clearance opening 120. When the battery unit 300 is installed, the clearance opening sealing gasket 121 is in contact with the outer shell of the battery unit 300 to achieve a seal. By providing a clearance opening sealing gasket 121 surrounding the clearance opening 120, the battery connector 130 can be enclosed within the clearance opening sealing gasket 121, thereby improving waterproof performance and contributing to the reliable operation of the AED device.

[0114] The aforementioned clearance opening 120 can be disposed on the side wall of the battery compartment 114 or on the bottom wall of the battery compartment 114. In one embodiment, the clearance opening 120 is disposed on the bottom wall of the battery compartment 114, and the clearance opening sealing gasket 121 includes a side sealing portion 1211 and a bottom sealing portion 1212. The side sealing portion 1211 is fixed to the side wall of the battery compartment 114, and the bottom sealing portion 1212 is fixed to the bottom wall of the battery compartment 114. The sealing gasket with the above structure can adapt to the situation where the clearance opening 120 is disposed on the side wall of the compartment, especially when the corresponding side of the clearance opening 120 is formed by the side wall of the compartment or the distance between the clearance opening 120 and the side wall of the compartment is very small.

[0115] In one embodiment, a limiting rib 123 is provided on the side wall of the compartment. The limiting rib 123 is used to insert into the adapter limiting groove 313 on the side of the battery unit 300, which can ensure a stable relative positional relationship between the battery connector 130 and the host connector 310 and avoid electrical connection failure. The limiting rib 123 includes a first part spaced apart from the bottom wall of the compartment, a second part and a third part connected between the first part and the bottom wall of the compartment. The first part, the second part and the third part form a side sealing area on the side wall of the compartment, and the side sealing part 1211 is bonded to the side sealing area. The limiting rib 123 can also form a preliminary sealing structure, which is beneficial to improving the sealing effect; and the above structure can prevent the side sealing part 1211 from leaking out and peeling off due to disturbance from other structures.

[0116] However, the setting of the limiting rib 123 will affect the adhesion of the clearance sealing gasket 121. In order to improve this problem, the limiting rib 123 has a notch 1231 provided at the first part, the bottom surface of the notch 1231 is located on the same plane as the side sealing area, so that at least a part of the bonding area of ​​the side sealing part 1211 can be exposed through the notch 1231, which is conducive to more accurately and smoothly bonding the side sealing part 1211 to the side sealing area.

[0117] In one embodiment, a boss 124 is provided in the side sealing area, and a positioning groove is provided between the boss 124 and the limiting rib 123. The side sealing portion 1211 is located in the positioning groove. By providing the positioning groove, the bonding position of the side sealing portion 1211 can be positioned more accurately, which helps to ensure the flatness and sealing effect of the side sealing portion 1211.

[0118] The bottom sealing portion 1212 can be directly adhered to the bottom wall of the compartment. However, this would result in a high protrusion on the bottom wall, making it easy to damage the adhesion of the bottom sealing portion 1212 when disassembling or assembling the battery unit 300. In one embodiment, a sealing gasket receiving groove 125 is provided on the bottom wall of the compartment, and the bottom sealing portion 1212 is located in the sealing gasket receiving groove 125. The bottom surface of the sealing gasket receiving groove 125 has a slope 1251 on the side away from the side sealing area. The slope 1251 is used to make the depth of the corresponding part of the sealing gasket receiving groove 125 greater than that of the adjacent part. The sealing gasket receiving groove 125 not only allows for proper control of the protrusion of the bottom sealing portion 1212, but also allows for positioning of the bottom sealing portion 1212, which is beneficial for accurately adhering the bottom sealing portion 1212 to the battery compartment 114. Furthermore, the gradient structure formed by the slope 1251 allows the corresponding side edge of the bottom sealing portion 1212 to form a slope, which helps to prevent the battery unit 300 from lifting the bottom sealing portion 1212 during the installation of the battery unit 300. It should be noted that the function of the bottom sealing portion 1212 is to form a seal with the battery unit 300, therefore the top surface of the bottom sealing portion 1212 should slightly protrude from the sealing gasket receiving groove 125.

[0119] Please refer to Figure 27 and Figure 28 In one embodiment, the battery connector 130 is provided with an annular step 131 facing the clearance opening 120. The AED device includes a bottom sealing gasket 126, which is annular and used to seal the gap between the annular step 131 and the bottom wall of the battery compartment 114. The bottom sealing gasket 126, together with the clearance opening sealing gasket 121, forms a double seal, resulting in better sealing reliability.

[0120] Those skilled in the art will understand that the materials of the bottom sealing gasket 126 and the clearance sealing gasket 121 can be elastic to achieve a better sealing effect. For example, foam, silicone, rubber, etc. can be used.

[0121] In one embodiment, the battery unit 300 includes a battery housing 320, a connector board 341, and a battery cell 342. The connector board 341 includes a host connector 310 for connecting to a battery connector 130 disposed on the housing body 110. The battery housing 320 has an inner cavity, and the connector board 341 is disposed on one side of the inner cavity. A limiting member 343 is provided between the battery cell 342 and the connector board 341 for positioning the battery cell 342 and / or the connector board 341.

[0122] Please refer to Figure 29 and Figure 30 In one embodiment, the battery casing 320 includes a bottom shell 321 and a top cover 322 that are interlocked. The bottom shell 321 has an inner cavity. The battery cell 342 and the connector board 341 can be connected together and then fixed to the bottom shell 321. Then, the top cover 322 is fixed to the bottom shell 321. Please refer to... Figures 33 to 36 Different batteries can be positioned in different arrangements within the outer casing cavity, and positioning grooves for positioning batteries with two different positioning methods can be provided on the cavity wall of the outer casing cavity.

[0123] During the installation of the battery unit 300 into the battery compartment 114, an interaction force is generated between the host connector 310 and the battery connector 130. Therefore, it is necessary to ensure that the host connector 310 on the battery unit 300 and the battery connector 130 on the host 100 are stably fixed. For the host connector 310 on the battery unit 300, stable installation of the host connector 310 can be achieved by fixing the connector plate 341. Those skilled in the art will understand that the battery unit 300 should have an opening for exposing the host connector 310. In one embodiment, the connector plate 341 can be adhesively fixed to the cavity wall around the opening. At the same time, the limiting member 343 can support the connector plate 341 on the side closer to the cell 342, thereby maintaining the structural stability of the host connector 310 when subjected to the reverse force of the battery connector 130.

[0124] In one embodiment, please refer to Figure 31 , Figure 32 The limiting member 343 has a first limiting surface 3431 and a second limiting surface 3432. The first limiting surface 3431 abuts against the connector plate 341. The limiting member 343 protrudes from the surface of the corresponding mounting base. For example, the limiting member 343 protrudes from the cavity wall of the inner cavity of the housing. The second limiting surface 3432 is located on the side of the limiting member 343 away from the first limiting surface 3431. A limiting rib 2167 is provided between the second limiting surface 3432 and the mounting base. The positioning rib is perpendicular to the second limiting surface 3432. The side of the limiting rib 2167 forms an inclined limiting surface 3433 between the second limiting surface 3432 and the mounting base. The inclined limiting surface 3433 and / or the second limiting surface 3432 are used to support the battery cell 342. The first limiting surface 3431 can provide stable support for the connector board 341, ensuring reliable fixation of the host connector 310, while the positioning ribs help increase the structural strength of the limiting component 343.

[0125] In one embodiment, the limiting member 343 includes a first rib 2161, a second rib 2163, and a third rib. The first limiting surface 3431 is formed by the surface of the first rib 2161, and the second limiting surface 3432 is formed by the surface of the second rib 2163. The third rib connects the first rib 2161 and the second rib 2163, enabling the first limiting surface 3431 and the second limiting surface 3432 to form a larger support surface area, resulting in more dispersed and uniform force distribution on the connector plate 341 and the battery cell 342. In another embodiment, the number of limiting members 343 is not less than two, with a gap between adjacent limiting members 343. A cable is connected to the connector plate 341, and the connection point between the cable and the connector plate 341 corresponds to the gap. This structure prevents the cable from being pressed by the battery cell 342 during assembly.

[0126] To facilitate accurate support of the limiting member 343 on the connector board 341 during the installation of the top cover 322, in one specific embodiment, the limiting member 343 is provided with an angled surface 3434, which forms a guide surface for guiding the connector board 341 into position relative to the limiting member 343. In some other embodiments, an angled surface 3434 may also be provided to guide the battery cell 342 into position relative to the limiting member 343.

[0127] For scenarios with even greater capacity requirements, please refer to one embodiment. Figure 37 , Figure 38 The battery unit 300 further includes a cell support 350. The cell 342 has at least two layers, and the cell support 350 is isolated between and connected to the two layers of cells 342. The cell support 350 provides stable support for the two layers of cells 342. To ensure the stability of the cell support 350, it may include a support post 351, which supports at least one side wall of the inner cavity of the housing along the stacking direction of the cells 342. Additionally, the cell support 350 may have a snap-fit ​​arm 352 extending along the stacking direction of the cells 342, and a matching snap-fit ​​arm adapter 330 may be provided on the side wall of the inner cavity of the housing, thereby more reliably fixing the cell support 350. Furthermore, to better ensure the fixation of the cell support 350, in one embodiment, a positioning post protrudes from the bottom wall of the bottom shell 321, and the cell support 350 can be fixed to the positioning post with screws.

[0128] For a battery unit 300 with a cell support 350, the distance between the cell support 350 and the connector plate is closer, and the limiting member 343 can also be set on the cell support 350, which facilitates the positioning of the connector plate. In this case, the top cover 322 of the battery unit 300 can have a receiving cavity corresponding to the top cell 342, meeting the arrangement requirements of the double-layer cells 342. Correspondingly, a method such as... Figure 24 The cover 200 shown is used to close the battery compartment 114.

[0129] The above examples illustrate the present invention only to aid in understanding it and are not intended to limit the scope of the invention. Those skilled in the art can make various simple deductions, modifications, or substitutions based on the principles of this invention.
