Description

Technical Field

[0001] The utility model relates to the technical field of first aid training equipment, in particular to a battery assembly and an AED training machine. Background Art

[0002] The AED Trainer is a training tool designed for trainees that simulates the AED (Automated External Defibrillator) rescue process. By simulating real-world scenarios and providing real-time feedback, it aims to train non-professionals in AED use and improve their ability to respond to cardiac arrest patients.

[0003] During practical training, AED trainers are frequently used, leading to rapid battery drain and the need for frequent replacement of the battery cells. Existing AED trainers often have screw-fastened battery covers, making removal cumbersome and delaying training time. To facilitate continuous use during daily training, an AED trainer with quick battery replacement capabilities is urgently needed. Utility Model Content

[0004] In view of the above-mentioned defects, the technical problem to be solved by the present invention is to provide a battery assembly and an AED trainer. The battery assembly of the trainer is easy to disassemble and the battery cells can be quickly disassembled and replaced, reducing the time required for battery cell replacement.

[0005] The above technical objectives of the present invention are achieved through the following technical solutions:

[0006] In a first aspect, a battery assembly is provided, comprising a first shell and a second shell that are detachably connected together, the first shell and the second shell enclosing an installation space for installing a battery cell, a first boss being provided on the first shell, a button being movably connected to the second shell, a fixing member being provided on the inner side of the second shell, the button being installed between the fixing member and the second shell, a second boss corresponding to the first boss being provided on the button, an elastic member being provided in the installation space, one end of the elastic member being connected to the button, when the button is in a first working position, the first boss abuts against the second boss and restricts the second shell from being separated from the first shell, and when the button is in a second working position, the first boss disengages from the abutment with the second boss, and the elastic member is used to drive the button from the second working position to move to the first working position.

[0007] By adopting the above solution, in the initial state, the button is in the first working position, at which point the first and second bosses abut, preventing the second shell from separating from the first shell. When the battery cell needs to be replaced, the button is toggled from the first working position to the second working position, causing the first and second bosses to disengage, thereby unlocking the second shell and separating it from the first shell. After the battery cell is installed in the installation space, the button is toggled to the second working position, the second shell is snapped into place with the first shell, and then the button is released. The elastic force of the elastic member causes the button to move from the second working position to the first working position. Once the button reaches the first working position, the first and second bosses abut, preventing the second shell from separating from the first shell. Since the button is mounted between the fixing member and the second shell, after the second shell is separated from the first shell, the button is confined between the fixing member and the second shell and will not separate from the second shell, making it more convenient to use.

[0008] Preferably, the first boss is arranged toward the inside of the installation space, and the second boss is arranged toward the outside of the installation space.

[0009] Preferably, the button is provided with a receiving groove, the elastic member is disposed in the receiving groove, a baffle is provided on the inner side of the second housing, and the ends of the elastic member abut against the receiving groove and the baffle, respectively. Since the elastic member is disposed in the receiving groove, the structure is more compact, saving space occupied by the elastic member.

[0010] Preferably, the elastic member is a spring, and a positioning protrusion is provided in the receiving groove, and one end of the spring is sleeved on the positioning protrusion. Since the spring is sleeved on the positioning protrusion, it is more convenient to install the spring, and the spring can limit the installation position of one end of the spring, thereby improving the stability of the spring during use.

[0011] Preferably, a first positioning block is provided on the inner side of the second housing, and a second positioning block is provided on the fixing member to correspond to the first positioning block. The end of the spring that abuts the baffle is located between the first positioning block and the second positioning block. The first and second positioning blocks jointly limit one end of the spring, further enhancing the stability of the spring during use.

[0012] Preferably, the second housing is provided with a mounting hole, and the button is provided with a toggle portion, which passes through the mounting hole and extends to the outside of the second housing. The toggle portion can conveniently drive the button to switch between the first working position and the second working position.

[0013] Preferably, a groove is provided on the second housing at a position corresponding to the mounting hole, the mounting hole is located at the bottom of the groove, and the toggle portion is located within the groove. Since the toggle portion is located within the groove, accidental contact with the toggle portion during use can be avoided, thereby preventing the second housing from being separated from the first housing by accidental operation.

[0014] Preferably, at least one stopper is provided on the end of the second housing opposite the button, and a stopper hole corresponding to the stopper is provided on the first housing, with the stopper being inserted into the corresponding stopper hole. The stopper provided on the end of the second housing opposite the button is connected to the stopper hole on the first housing by plugging, which facilitates removal of the stopper and the stopper hole, thereby facilitating disassembly of the second housing from the first housing.

[0015] Preferably, a first guiding bevel is provided at the end of the first boss, and a second guiding bevel corresponding to the first guiding bevel is provided at the end of the second boss. When the second shell approaches the first shell, the first guiding bevel and the second guiding bevel cooperate to move the button toward the second working position. Due to the provision of the first guiding bevel and the second guiding bevel, when the second shell is installed on the first shell, the second shell gradually approaches the first shell, and the first boss of the button and the second boss on the first shell also gradually approach each other. When the first guiding bevel and the second guiding bevel come into contact, the button moves toward the second working position under the guidance of the first guiding bevel and the second guiding bevel until the first guiding bevel and the second guiding bevel are out of contact; at this time, under the elastic force of the elastic member, the button moves to the first working position, so that the first boss and the second boss abut against each other, thereby locking the second shell and the first shell together. When installing the second shell and the first shell together, there is no need to move the button to the second working position in advance. It is only necessary to apply pressure to the button in the direction of the first shell. Under the guidance of the first guide bevel and the second guide bevel, the first boss can smoothly reach the position of abutting against the second boss, which is more convenient to use.

[0016] In a second aspect, an AED training machine is also provided, comprising the above-mentioned battery assembly.

[0017] In summary, the battery assembly provided by the present invention has at least the following beneficial effects:

[0018] 1. The first shell and the second shell can be quickly disassembled and installed, saving time for replacing battery cells.

[0019] 2. The overall structure is compact, which can leave a larger installation space for the battery cells, so that multiple battery cells can be installed to increase the total power. BRIEF DESCRIPTION OF THE DRAWINGS
