[0022] Example:

[0023] like Figure 1-3 As shown, in the first embodiment of the utility model, the battery assembly is applied to a medical device, and the medical device is provided with an installation cavity for installing the battery assembly, and a locking groove is formed on the installation cavity. The battery assembly includes a housing 1, a battery 2, a circuit board 3, and a snap-fit ​​assembly 4; the battery 2 and the circuit board 3 are respectively fixed in the housing 1, and the circuit board 3 is connected to one end of the battery 2; the snap-fit ​​assembly 4 includes an elastic member 41 fixed to the housing 1 and a lock 42 connected to the elastic member 41, and when the battery assembly is placed in the installation cavity, the lock 42 is used to enter and exit the locking groove under the action of external force and the elastic force of the elastic member 41.

[0024] Specifically, the present application adopts the method of locking the buckle 42 to realize the installation and fixation with the whole medical device. During installation, the battery assembly is placed in the installation cavity as a whole, and the buckle 42 is forced to move in the compression direction of the elastic member 41. After the position is aligned, the external force applied to the buckle 42 is removed, and the elastic member 41 automatically rebounds so that the buckle 42 can enter the locking groove under the action of the elastic force, thereby the battery assembly can be locked and fixed with the medical device; when the battery assembly needs to be replaced, only a certain external force is applied to the buckle 42 to make it withdraw from the locking groove of the medical device to remove the battery assembly from the installation cavity, which is easy to operate and has a long service life.

[0025] In this embodiment, the housing 1 includes an upper cover 11 with an assembly opening 111; an elastic member 41 is located inside the upper cover 11; a lock 42 includes a main body fixed to the end of the elastic member 41 and a locking edge 423 connected to the main body on a side away from the elastic member 41; when the elastic member 41 is in a natural state, the locking edge 423 is located outside the assembly opening 111. The elastic member 41 may be a spring, and one or more springs may be provided. When there are multiple springs, the multiple springs are symmetrically arranged. The position and shape of the locking edge 423 are adapted to the position and shape of the locking groove on the medical device. When the lock buckle 42 is in a locked state, the elastic member 41 is in a naturally extended state, so that the locking edge 423 is located outside the assembly port 111 and is inserted into the locking groove of the medical device, thereby achieving a firm fixation of the battery assembly and the medical device; when the battery assembly needs to be removed, force is applied to the lock buckle 42 to move it into the assembly port 111 until the lock buckle 42 is separated from the locking groove, and the entire battery assembly can be directly pulled out of the installation cavity. The operation is simple and there is no need to damage any parts of the medical device.

[0026] In this embodiment, the main body includes a connecting portion 421 connected to the elastic member 41 and an operating portion 422 connected to a side of the connecting portion 421 away from the elastic member 41; the operating portion 422 and the locking edge 423 are spaced apart from each other, and the locking edge 423 is located at an end of the operating portion 422 away from the top of the upper cover 11. Specifically, the end of the elastic member 41 is embedded in a side of the connecting portion 421 away from the operating portion 422. The connecting portion 421, the operating portion 422 and the locking edge 423 can be an integrally formed structure; or they can be separate components, and the separate components can be connected into one by mechanical connection (such as bonding, clamping, screw fixing, etc.). The operating portion 422 is used for user operation. When the battery assembly needs to be installed, when the battery assembly is loaded into the installation cavity, the upper cover 11 faces the outside of the exit of the installation cavity of the medical device. The locking edge 423 is located at the end of the operating portion 422 away from the top of the upper cover 11, that is, the operating portion 422 is close to the top of the upper cover 11. The user can apply a thrust to the operating portion 422 to make it return to the upper cover 11 to achieve unlocking, which is convenient for operation. In this embodiment, the first side surface of the operating portion 422 that is away from the connecting portion 421 is provided with an anti-slip protrusion. Preferably, a plurality of strip-shaped anti-slip protrusions are provided, and each anti-slip protrusion is arranged at intervals on the side of the operating portion 422 away from the connecting portion 421, which can further enhance the user's operating feel.

[0027] In this embodiment, a blocking portion extending in the direction of cross-sectional contraction is formed on one side of the assembly opening 111, and the blocking portion is at least partially opposite to the second side of the operating portion 422 away from the anti-slip protrusion. The distance from the blocking portion to the outer wall of the upper cover 11 is greater than the distance from the first side to the second side. That is, the assembly opening 111 is provided with a blocking portion extending in the direction of the diameter reduction, when the user applies a thrust to the operating portion 422 to move it in the direction of the elastic member 41, after the locking edge 423 moves into the assembly opening 111 (when the distance from the side of the locking edge 423 away from the operating portion 422 to the elastic member 41 is less than or equal to the distance from the side wall corresponding to the upper cover 11 to the elastic member 41), the blocking portion will form a block on the operating portion 422 to prevent the user from continuing to apply force or applying too much force and other erroneous operations, causing the operating portion 422 and the entire main body to continue to move toward the elasticity and cause certain damage to the elastic member 41 and other components. When the elastic member 41 is in a naturally extended state, the distance from the second side of the operating portion 422 that is away from the anti-slip protrusion to the blocking portion is greater than or equal to the distance from the outer side of the locking edge 423 to the connecting portion 421, that is, a movable space for the operating portion 422 and the locking edge 423 to move is formed on the assembly port 111, so as to ensure that the lock buckle 42 can move to a certain position on the assembly port 111.

[0028] In this embodiment, two lock buckles 42 are provided, and the two lock buckles 42 are respectively connected to the two ends of the elastic member 41 to ensure that the battery assembly can be firmly fixed to the medical device when it is installed in the medical device. In a specific implementation of this embodiment, the elastic member 41 is a single spring, and the size of the spring and the lock buckle 42 is determined according to actual conditions. The two lock buckles 42 are symmetrically connected to the two ends of the spring. When installation is required, a force is applied to the two lock buckles 42 respectively to move them in the direction of spring compression until the two locking edges 423 are respectively returned to the assembly port 111. After the positions are aligned, the force applied to the operating part 422 is canceled. When disassembly is required, the corresponding operations of pushing the operating part 422 into the upper cover and pulling out the battery assembly as a whole are performed, which will not be repeated here.

[0029] In this embodiment, the housing 1 further includes a shell body 12 having a battery compartment 121 and a fixing member 13 connected between the shell body 12 and the upper cover 11; the battery 2 is fixed in the battery compartment 121, and the circuit board 3 is fixed to a side of the fixing member 13 away from the upper cover 11. The fixing member 13, the circuit board 3 and the shell body 12 are fixed to each other by mechanical connection.

[0030] Specifically, in this embodiment, the number of battery installation positions for accommodating batteries 2 provided in the battery compartment 121 may be one or more, and the number of batteries 2 corresponds to the number of battery installation positions. In a specific implementation of this embodiment, the number of battery installation positions and batteries 2 are both set to four, and the circuit board 3 is provided with a connector; during assembly, the spring and the two locks 42 may be fixed first, and then the spring and the locks 42 may be installed as a whole into the upper cover 11, and then the fixing member 13 may be covered on the bottom of the upper cover 11, and the upper cover 11 and the fixing member 13 may be fixed by screws; then the circuit board 3 may be fixed to the side of the fixing member 13 facing away from the upper cover 11, and each battery 2 may be installed into the battery compartment 121, and finally the battery compartment 121 and the fixing member 13 may be fixed. It can be understood that in the present application, the fixing method between the circuit board 3 and the fixing part 13, and the fixing part 13 and the shell body 12 can be welding fixing (for example: ultrasonic welding), which has a good fixing effect; the fixing method between the circuit board 3 and the fixing part 13, and the fixing part 13 and the shell body 12 can also be screw fixing, which is convenient for disassembly and replacement of various components in the battery group 2.

[0031] like Figure 3 As shown, another aspect of the utility model provides a medical device, including the battery assembly described in the first aspect of the present application and an installation cavity for installing the battery assembly, and a locking groove corresponding to the shape and position of the lock buckle 42 is formed on the installation cavity.

[0032] Specifically, the medical device includes a medical device body 01 and a battery assembly, and a mounting cavity is provided on the body 01. The medical device in this embodiment may be a defibrillator monitor, or other medical device that requires the installation of a battery 2, such as a ventilator, a medical lighting lamp, etc. The shape of the mounting cavity is adapted to the shape of the battery assembly. After the battery assembly is installed, the medical device can be powered by the interaction of components such as the battery 2, the circuit board 3 and its connector. In some specific implementations of this embodiment, a clearance groove 011 may also be provided outside the mounting cavity, so that when the battery assembly is installed in the medical device, the operating portion 422 is directly opposite to the clearance groove 011, so that the operating portion 422 and the clearance groove 011 form a clearance space, which makes it more convenient for the user to operate the operating portion 422 in the clearance space to achieve unlocking.

[0033] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
