[0030] Please refer to Figures 1-7 The utility model discloses a detachable battery pack, including battery shell 1, the inside of battery shell 1 is equipped with multiple batteries 2, multiple batteries 2 both sides are equipped with electric connection assembly 3, and the electric connection assembly 3 of same side multiple one end is equipped with conductive plate 4, and the conductive plate 4 is fixedly installed on battery shell 1, and the inside of battery shell 1 and located one side of multiple batteries 2 is equipped with cooling assembly 5, and the both ends of cooling assembly 5 are arranged in pump body 6 respectively.

[0031] In this battery pack, the battery casing 1 serves as a container, housing multiple batteries 2.

A cooling component 5 is installed on one side of the multiple batteries 2, with both ends connected to a pump body 6. The electrical connection components 3 are connected to the positive and negative terminals of the batteries 2, connecting them in series to meet the voltage and current requirements of different devices.

[0032] Connection between electrical connection assembly 3 and conductive plate 4: Multiple electrical connection assemblies 3 on the same side are connected at one end to conductive plate 4. Conductive plate 4 serves as a centralized current transmission path, outputting the battery pack's electrical energy to external devices. The electrical connection assembly 3 and conductive plate are rotatably mounted. This design allows for flexible adjustment of the position of the electrical connection assembly 3 when replacing the battery, facilitating the removal and installation of battery 2. When the battery pack is operating, the battery generates heat. To prevent excessively high battery temperatures from affecting performance and lifespan, a cooling assembly 5 is provided. Pump body 6 drives a cooling medium (such as coolant) to circulate within the cooling assembly 5. The cooling medium absorbs the heat generated by the battery and then carries it away, thereby achieving continuous cooling of the battery.

[0033] In one embodiment, the battery housing 1 includes a base 101, a housing 102 is provided on the top of the base 101, and a mounting groove 103 for mounting the battery 2 is fixedly installed on the top of the base 101 and inside the housing 102.

[0034] An insulating mounting plate 104 is fixedly installed on the top of the outer casing 102, and two conductive plates 4 are fixedly installed on the insulating mounting plate 104.

[0035] The base 101 serves as the basic support structure, bearing the weight of the entire battery pack and providing a stable mounting platform for other components. The outer casing 102 protects the internal battery 2, electrical connection assembly 3, conductive plate 4, and cooling assembly 5 from external environmental influences. Simultaneously, the outer casing 102 helps maintain stable temperature and humidity inside the battery pack, ensuring the normal operating environment of the battery 2. The mounting slot 103 design allows the battery 2 to be accurately installed in a specific position, ensuring proper spacing between batteries 2 and preventing mutual interference and collisions. The mounting slot 103 also restricts battery movement, improving battery stability during operation. The insulating mounting plate 104 provides insulation, preventing electrical short circuits between the conductive plate 4 and the outer casing 102. Simultaneously, the insulating mounting plate 104 provides a fixed mounting position for the conductive plate 4, ensuring its stability.

[0036] In one embodiment, for the above-mentioned battery 2, the top of the battery 2 is respectively provided with a positive plate 201 and a negative plate 202, both of which are fixedly provided with a metal mounting plate 203, and the electric connection assembly 3 comprises a conductive screw 301.

[0037] The conductive screw 301 is threadedly mounted on the metal mounting plate 203 in the positive plate 201 and the negative plate 202, and a conductive dismounting plate 302 is arranged between the conductive screw 301 and the metal mounting plate 203.

[0038] The conductive dismounting plate 302 is electrically connected with the metal mounting plate 203 and the conductive screw 301, and the other end of the conductive dismounting plate 302 is fixedly provided with a conductive rod 303, which is rotatably mounted on the conductive plate 4.

[0039] The conductive screw 301 is threadedly mounted on the metal mounting plate 203 in the positive plate 201 and the negative plate 202. The conductive screw 301 serves to connect the electrodes of the battery 2 and the conductive dismounting plate 302. Through threaded connection, the firmness and stability of the connection are ensured, and the dismounting and mounting are facilitated. The conductive dismounting plate 302 is arranged between the conductive screw 301 and the metal mounting plate 203. The conductive dismounting plate 302 serves to realize good electrical contact between the conductive screw 301 and the metal mounting plate 203, and also provides a transition for the subsequent connection with the conductive rod 303. The conductive dismounting plate 302 is electrically connected with the metal mounting plate 203 and the conductive screw 301, so as to ensure that the current can be smoothly conducted from the electrodes of the battery 2 through the conductive screw 301 and the conductive dismounting plate 302. The other end of the conductive dismounting plate 302 is fixedly provided with the conductive rod 303. The conductive rod 303 serves as a connecting bridge between the conductive plates 4, and transmits the current of the battery 2 to the conductive plates 4. The conductive rod 303 is rotatably mounted on the conductive plate 4. This rotatable mounting manner makes it possible to flexibly adjust the position of the conductive rod 303 when the battery is replaced, facilitating the dismounting and mounting of the battery, and thus realizing the replacement and dismounting of the battery 2. At the same time, the rotatable connection can ensure that the conductive rod 303 and the conductive plate 4 always maintain good electrical contact during the operation of the battery 2, so as to ensure the stable transmission of the current.

[0040] In one embodiment, for the above-mentioned cooling assembly 5, the cooling assembly 5 comprises a plurality of heat dissipation fins 501, and the heat dissipation fins 501 are respectively arranged between every two batteries 2. The two ends of the heat dissipation fins 501 are respectively fixedly provided with an inlet pipe 502 and an outlet pipe 503, and the inlet pipe 502 and the outlet pipe 503 are respectively arranged on the pump body 6.

[0041] The heat sink 501 is typically made of a material with good thermal conductivity, such as metal (copper, aluminum, etc.). When the battery 2 operates, it generates heat, which is conducted to the adjacent heat sink 501. The heat sink 501 quickly absorbs the heat generated by the battery 2 by increasing the contact area with the battery 2, thereby reducing the temperature of the battery 2. Since the heat sink 501 is installed between pairs of batteries 2, it can effectively dissipate heat from each battery 2, avoiding localized overheating. The inlet pipe 502 and outlet pipe 503 are responsible for introducing the cooling medium into the heat sink 501 and discharging the cooled medium that has absorbed heat from the heat sink 501, respectively. The cooling medium can be a liquid with good heat absorption and transfer properties, such as a coolant. The pump body 6 drives the cooling medium to circulate in the inlet pipe 502, heat sink 501, and outlet pipe 503, forming a continuous cooling cycle. In this way, the inlet pipe 502, heat sink 501, and outlet pipe 503 can effectively remove the heat generated by the battery 2, keeping the battery 2 operating within a suitable temperature range, improving the performance and lifespan of the battery 2.
