Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work belong to the protection scope of the present invention.

[0031] Embodiment 1:

[0032] The utility model provides a battery installation structure 10, such as Figure 1As shown, it includes a battery holder 11 detachably connected to the circuit board 01, and the surface of the battery holder 11 facing away from the circuit board 01 or facing the side of the circuit board 01 is provided with a mounting groove 12 for accommodating the battery 02, and the circuit board 01 is connected to the battery 02 through the battery holder 11; in one embodiment, the circuit board 01, the battery 02 and the battery holder 11 are stacked, and compared with the prior art, the volume of the structure in the present application after assembly is greatly reduced; in one embodiment, the battery 02 is placed horizontally in the mounting groove; the shape of the mounting groove 12 is adapted to the shape of the battery, so that the battery can be initially positioned; a high-voltage area is provided on the side of the battery holder 11 facing the circuit board 01 corresponding to the positive electrode of the battery 02, and a low-voltage area is provided on the other side corresponding to the negative electrode of the battery 02; a baffle plate 13 is provided between the high-voltage area and the battery 02; a reinforcing rib 131 is provided on the outer edge of the baffle plate 13 to isolate the high-voltage components on the circuit board 01 from the battery 02.

[0033] The battery mounting structure is cleverly designed. The circuit board and the battery assembly can be connected together through the battery bracket. The battery bracket not only has the function of fixing and accommodating the battery, but also has the function of connecting the circuit board and the battery. The high-voltage area and the battery can be separated by the baffle plate, thereby preventing the high-voltage test from failing and meeting the vertical distance required by safety regulations. The reinforcing ribs on the baffle plate can separate the high-voltage components on the circuit board from the battery, further meeting the creepage distance required by safety regulations and achieving electrical isolation between the battery and the circuit board, thereby improving the safety and reliability of battery use.

[0034] Furthermore, the thickness of the reinforcing rib 131 is not less than the creepage distance of the battery 02. For example, the creepage distance of a common battery is 5 mm, and the thickness of the reinforcing rib 131 is greater than or equal to 5 mm, satisfying the creepage distance of the battery.

[0035] Furthermore, the battery holder 11 includes a substrate 111 for horizontally placing the battery 02; a support plate 112 is provided between the battery 02 and the low-voltage zone; in one embodiment, the substrate 111 is an arc-shaped structure adapted to the outer contour of the cylindrical battery.

For example, a mobile power source includes an upper shell and a lower shell, a battery holder 11 is assembled on the lower shell, and a baffle plate 13 is fixedly installed on the upper shell. When the lower shell is buckled downward with the lower shell, the baffle plate 13 is inserted between the battery and the high-voltage area to isolate the battery from the high-voltage area, which can prevent the high-voltage test from failing and meet the safety regulations for vertical distance and creepage distance; optionally, the support plate 112 can also be an isolation plate to isolate the battery from the low-voltage area, which can increase the service life of the battery and make it safer to use. Based on the same installation principle, the support plate 112 can also be a separate component, and the baffle plate 13 is fixedly connected to the base plate 111, which is easy to operate;

[0036] like Figure 1 As shown, the circuit board 01 is located on the side surface of the battery holder 11 facing away from the mounting groove 12, so that the circuit board 01 and the battery 02 are respectively located on the opposite sides of the battery holder 11. At this time, the battery holder 01 has the function of isolating the battery from the circuit board, thereby separating the heat on the circuit board from the heat of the battery; the reinforcing rib 131 is bent toward the circuit board 01 to facilitate the later connection with the circuit board; the reinforcing rib 131 protrudes from the outside of the battery holder, which can ensure that the circuit board 01 and the battery holder 11 maintain a certain distance, further ensuring the creepage distance; a fixing block 011 is provided on the side of the circuit board 01 facing the baffle plate 13; as shown Figure 2 As shown, what is shown is the structural assembly diagram of the battery mounting structure 10; a slot 012 which cooperates with the reinforcing rib 131 is provided on the fixing block 011; the end of the reinforcing rib 131 away from the mounting slot 12 is bent toward the fixing block 011 on the circuit board, and is cooperated with the slot 012 on the fixing block 011 for easy assembly. The reinforcing rib can not only connect the circuit board, but also isolate the high-voltage components on the circuit board 01 from the battery 02.
