[0023] Example:

[0024] like Figure 1-5 As shown, in this embodiment, the battery fixing assembly includes: a battery compartment 1 formed with a receiving slot 11 and an upper cover 2 for slidingly covering and fixing with the receiving slot 11, a card slot 13 and a first magnetic block 12 are arranged on the outer periphery of the notch of the receiving slot 11, the upper cover 2 is provided with a buckle 23 which cooperates with the card slot 13 in the sliding direction of the upper cover 2 and a second magnetic block 22 corresponding to the first magnetic block 12, and the polarities of the adjacent sides of the first magnetic block 12 and the second magnetic block 22 are opposite; the first magnetic block 12 and the second magnetic block 22 are offset in the sliding direction of the upper cover 2 so as to provide a restoring force to the upper cover 2 to make the buckle 23 and the card slot 13 engage.

[0025] Specifically, the battery fixing assembly provided in this embodiment is suitable for electrically driven devices such as AED automatic external defibrillators. The receiving slot 11 can be used to place batteries. While using the buckle 23 and the slot 13 to buckle and fix the battery compartment 1 and the battery compartment 1, magnetic blocks are also provided on the battery compartment 1 and the upper cover 2 respectively. When the upper cover 2 is covered outside the receiving slot 11, the slot 13 and the buckle 23 are buckled and fixed, the first magnetic block 12 and the second magnetic block 22 are at least partially opposite, and the ends of the first magnetic block 12 and the second magnetic block 22 that are close to each other attract each other. The magnetic attraction force between the magnetic blocks can make the upper cover 2 and the receiving slot 11 cover more firmly, and it is also easier to achieve the position alignment of the receiving slot 11 and the upper cover 2 when covering, and the operation is more convenient. The service life of the battery fixing assembly is longer.

[0026] In this embodiment, a rotating shaft is provided at one end of the upper cover 2 away from the second magnetic block 22, and the battery compartment 1 has an assembly hole 14 corresponding to the position of the rotating shaft, and the rotating shaft is movably assembled in the assembly hole 14. By applying a force to the upper cover 2, the upper cover 2 can be turned over along the central axis of the rotating shaft, so that the battery can be placed in or taken out of the receiving slot 11. In addition, compared with the traditional setting method of connecting the upper cover 2 and the battery compartment 1 only by the buckle 23, the setting method of rotating the upper cover 2 to connect the battery compartment 1 in this embodiment is more conducive to preventing the upper cover from falling off and being lost.

[0027] In this embodiment, the length of the assembly hole 14 in the sliding direction of the upper cover 2 is greater than the diameter of the rotating shaft. Specifically, a protrusion is formed on the side of the receiving groove 11 away from the first magnetic block 12, and two symmetrical waist holes, namely the assembly hole 14, are formed in the assembly hole 14. The two rotating shafts are used to rotate along their central axis and / or move along the guide surface, so that the upper cover 2 and the receiving groove 11 can be aligned during the covering process. Furthermore, the guide surface is parallel to the notch end surface of the receiving groove 11. The setting of the guide surface of the assembly hole 14 allows the upper cover 2 to move relative to the receiving groove 11 in the horizontal direction, which is more conducive to the buckle 23 and the groove 13. The buckle 23 and the groove 13 are more convenient to be fixed.

[0028] In this embodiment, the first magnetic block 12 is located on the side of the receiving groove 11 away from the assembly hole 14. When the upper cover 2 is covered outside the receiving groove 11, the distance between the first magnetic block 12 and the groove wall of the receiving groove 11 is not equal to the distance between the second magnetic block 22 and the groove wall of the receiving groove 11. That is, the projections of the first magnetic block 12 and the second magnetic block 22 in the height direction do not overlap, and the polarities of the ends of the first magnetic block 12 and the second magnetic block 22 that are close to each other are opposite, and there is a force of mutual attraction, which can make the battery compartment 1 and the upper cover 2 cover and fix more firmly. More specifically, the distance between the first magnetic block 12 and the groove wall of the receiving groove 11 is smaller than the distance between the second magnetic block 22 and the groove wall of the receiving groove 11. When covering, the first magnetic block 12 can generate a magnetic attraction force on the second magnetic block 22 toward the receiving groove 11, so that the upper cover 2 can automatically slide to the side where the assembly hole 14 is located under the action of the magnetic attraction force until the position is aligned (when the position is aligned, the shaft is located on the side of the mounting hole away from the receiving groove 11).

[0029] In this embodiment, the inner wall of the slot 13 is connected with a snap-fitting portion 131 for snapping and fixing with the snap 23, and a clearance space for the snap 23 to enter and exit is formed in the slot 13. The position movement of the snap 23 is restricted by the slot 13 and the snap-fitting portion 131, respectively, so that the snap 23 is more firmly engaged. The snap 23 can be an L-shaped limit buckle. Specifically, the snap 23 includes a first end connected to the upper cover 2 and a second end vertically connected to the first end. The inner wall of the slot 13 and the snap-fitting portion 131 form a sub-slot that matches the shape of the second end, and the sub-slot is connected to the clearance space. When the upper cover 2 is closed, the second end first enters the clearance space, and then the upper cover 2 is moved from the side where the second magnetic block 22 is located to the side where the rotating shaft is located through external force and / or magnetic attraction, so that the second end moves with the main body of the upper cover 2 into the sub-groove and is engaged with the groove wall of the sub-groove (the first end is located in the clearance space at this time), thereby realizing the engagement fixation between the buckle 23 and the groove 13, and the fixing effect is good.

[0030] In this embodiment, the receiving slot 11 is a square slot, the buckle 23 and the slot 13 can be set in one group or multiple groups, and at least two slots 13 are spaced apart on the opposite sides of the outer periphery of the slot opening of the receiving slot 11; the embedded portion 131 on the slot 13 is located at the top of the slot 13, and / or the embedded portion 131 on the slot 13 is located at the end of the slot 13 away from the receiving slot 11. Preferably, two groups of intervals are respectively arranged on opposite sides of the receiving slot 11 (the two sides adjacent to the side where the first magnetic block 12 is located), and the positions of the locking portions 131 of the two slots 13 on the same side are arranged differently: one locking portion 131 is arranged at the top of the slot 13 (the side of the locking portion 131 away from the sub-slot is flush with the end face of the notch of the receiving slot 11), and the other locking portion 131 is arranged at the side of the slot 13 away from the receiving slot 11, and the installation direction of each buckle 23 matches the setting mode of the corresponding slot 13, that is, the second end of one buckle 23 is perpendicular to the first end in the height direction and is bent downward, and / or the second end of another buckle 23 is perpendicular to the first end in the horizontal direction and is bent outward of the receiving slot 11. In this way, the position restriction of the buckle 23 in the horizontal direction and the height direction can be achieved, and the buckling effect is good.

[0031] In this embodiment, a limiting groove is provided in the battery compartment 1, and the first magnetic block 12 is embedded in the limiting groove. A fixing portion 21 for mounting the second magnetic block 22 is provided on the side of the upper cover 2 facing the receiving groove 11, and a clearance groove matching the shape and position of the fixing portion 21 is formed at the edge of the notch of the receiving groove 11. When the upper cover 2 is covered outside the receiving groove 11, the fixing portion 21 is located in the clearance groove. The second magnetic block 22 and the fixing portion 21 are fixed by a sealant.

[0032] Specifically, the first magnetic block 12 and the second magnetic block 22 may also be provided in one or more groups correspondingly. The shape of the limiting groove is adapted to the first magnetic block 12, so that the first magnetic block 12 can be firmly embedded in the limiting groove, and the fixing effect is good. The fixing portion 2121 is two limiting plates arranged at intervals, and the second magnetic block 22 is embedded between the two limiting plates. Furthermore, the fixing portion 2121 and the second magnetic block 22 may be reinforced and fixed by glue to prevent the second magnetic block 22 from falling off. It is understandable that in some other embodiments, the first magnetic block 12 and the battery compartment 1, and the second magnetic block 22 and the upper cover 2 can be fixed by means of card embedding or card embedding + glue, which is not limited here.

[0033] In this embodiment, both the upper cover 2 and the receiving groove 11 are provided with abutment members 24 for abutting and fixing with the battery. One or more battery installation positions can be set in the receiving groove 11, and one or more abutment members 24 can also be provided, and the abutment members 24 at the bottom of the receiving groove 11 and the abutment members 24 on the upper cover 2 can have the same or different shapes, and the shape of each abutment member 24 is adapted to the shape of the battery, so that the battery is not easy to loosen or misalign when placed in the receiving groove 11, and the fixing effect is good.

[0034] 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.
