[0050] Currently, in order to reduce the occurrence of safety accidents caused by battery overheating, a temperature sensor (for example, an NTC (Negative Temperature Coefficient, abbreviated as NTC) temperature sensor) is usually arranged on the surface of a battery cell to monitor the battery temperature in real time. In some cases, the temperature sensor needs to be fixed on a temperature sensor fixing bracket by dispensing, and then the temperature sensor fixing bracket and the isolation plate assembly are assembled and fixed. Too many components increase the height of the battery, and the temperature sensor fixing bracket is pressed under the connecting sheet, which is high in maintenance cost, and the installation process is complicated and high in cost. At the same time, in some cases, it is difficult to install the protective cover of the temperature sensor in place, which increases the production cost and reduces the production efficiency.

[0051] In order to reduce the difficulty of assembling the isolation plate assembly and enable the isolation plate assembly to be effectively installed in place, a first clamping structure and a second clamping structure that cooperate with each other can be used, so that the protective cover can be inserted into the accommodating seat along the first direction X, the assembly process is simple, and after being inserted, the protective cover is installed in place with the accommodating seat, without the need for multiple detection procedures to achieve effective installation.

[0052] Based on the above considerations, an isolation plate assembly is designed, which uses a first clamping structure and a second clamping structure that cooperate with each other to reduce the difficulty of assembling the isolation plate assembly and enable the isolation plate assembly to be effectively installed in place.

[0053] The isolation plate assembly disclosed in the embodiments of the present application can be used in a battery. The power supply system of the electrical device can be composed of the isolation plate assembly disclosed in the present application.

[0054] Referring to FIG. 1, and further referring to FIGS. 2 to 6. FIG. 1 is a structural schematic diagram of an isolation plate assembly 100 according to some embodiments of the present application; FIG. 2 is an enlarged view of the A part circled in FIG. 1; FIG. 3 is an enlarged view of the B part circled in FIG. 2; FIG. 4 is a partial structural schematic diagram of the isolation plate assembly 100 after assembly according to some embodiments of the present application; FIG. 5 is a structural schematic diagram of a protective cover 150 according to some embodiments of the present application; and FIG. 6 shows the structural schematic diagram of the protective cover 150 of FIG. 5 from another side. The isolation plate assembly 100 includes an isolation plate body 110 and a protective cover 150. The isolation plate body 110 is provided with an accommodating seat 120, and the accommodating seat 120 includes a first side wall 130 parallel to the vertical direction Z. The first side wall 130 is provided with a first clamping structure 140. The protective cover 150 cooperates with the accommodating seat 120 to define an accommodating space. The protective cover 150 includes a protective cover body 160 and a second clamping structure 170 connected to the protective cover body 160. The second clamping structure 170 is configured to be clamped with the first clamping structure 140, so that the protective cover 150 can be inserted into the accommodating seat 120 along the first direction X intersecting the vertical direction Z.

[0055] As shown in the figure, the first direction X in the figure is the length direction of the protective cover 150, and the vertical direction Z is the thickness direction of the protective cover 150.

[0056] In some embodiments, the accommodating seat 120 is a part of the isolation plate body 110. In some embodiments, the accommodating seat 120 is detachably mounted on the isolation plate body 110. As shown in FIG. 3, in some embodiments, the accommodating seat 120 includes a bottom wall (not shown in the figure), a first side wall 130, and a second side wall 240 adjacent to the first side wall 130. The protective cover 150 cooperates with the bottom wall, the first side wall 130, and the second side wall 240 of the accommodating seat 120 to define an accommodating space. It can be understood that the accommodating seat 120 and the accommodating space can be of any shape to accommodate any components in the battery 700 (FIG. 7). In some embodiments, the shape of the accommodating space matches the shape of the components placed in the accommodating space to achieve the effect of fixation. In some embodiments, the components placed in the accommodating space are the temperature sensor 105 and the heat-conducting pad 115. In some embodiments, an opening is provided on the bottom wall of the accommodating seat 120, and the heat-conducting pad 115 penetrates through the opening to be in thermal contact with the battery monomer 710 to be sensed, and the temperature sensor 105 is mounted on the heat-conducting pad 115 and placed in the accommodating space. The temperature sensor 105 obtains the temperature information of the battery monomer 710 through the heat-conducting pad 115 in direct contact with the battery monomer 710. In some embodiments, the temperature sensor 105 is an NTC sensor. In some embodiments, the heat-conducting pad 115 is made of an elastic high-thermal-conductivity material, such as a heat-conducting polymer. Under the pressure of the protective cover 150, the heat-conducting pad 115 is easily elastically compressed, better playing the role of heat conduction. In some embodiments, the protective cover 150 refers to any element for protecting the components placed in the accommodating space.

[0057] By adopting the first and second clamping structures that cooperate with each other, the protective cover can be inserted into the accommodating seat along the first direction, the assembly process is simple, and after being inserted, the protective cover is mounted in place with the accommodating seat, without the need for multiple detection procedures to achieve effective installation, thereby reducing the difficulty of assembling the isolation plate assembly and enabling the isolation plate assembly to be effectively installed in place.

[0058] According to some embodiments of the present application, the first clamping structure 140 includes a first limiting channel 180 near a portion of the second side wall 240 abutting the first side wall 130.

Correspondingly, the protective cover 150 is provided with the first elastic bending portion 200. The second end 220 of the first elastic bending portion 200 is elastically deformable along the vertical direction Z under the action of an external force, and automatically rebounds in the absence of the external force.

[0060] In some embodiments, the first elastic bending portion 200 is made of an elastic material, such as plastic.

[0061] In such a design, the second end of the first elastic bending portion of the second clamping structure can be elastically bent during insertion into the accommodating seat, and automatically rebounds to restore its original shape after being inserted into place, thereby facilitating simplification of the assembly process.

[0069] In the example shown in FIGS. 3 and 4, the first limiting surface 260 of the first notch 250 is in abutment with the upper surface of the first elastic bending portion 200 when the first end 210 of the first elastic bending portion 200 is inserted in the first notch 250.

[0070] By providing the first limiting surface, the first end can be limited in the vertical direction.

[0071] With continued reference to FIGS. 4-6, in some embodiments, the second engaging structure 170 further includes a first protruding portion 270 extending from the side of the cover 150 in a second direction Y.

The portion of the first engaging structure 140 distal from the second side wall 240 further includes a first recessed portion 280. The first recessed portion 280 is configured to receive the first protruding portion 270.

[0072] As shown in the figures, the second direction Y is the width direction of the cover 150.

[0073] In the example shown in FIG. 4, the first protruding portion 270 extends into the first recessed portion 280 when the cover 150 is fully inserted in the receiving seat 120 in the first direction X.

[0074] By providing the first protruding portion and the first recessed portion that cooperate with each other, the rear end of the cover can be better limited when the first elastic bending portion is inserted in the first limiting passage.

[0075] With continued reference to FIGS. 3-6, the first recessed portion 280 has a second limiting surface 290 intersecting the vertical direction Z. The second limiting surface 290 engages the upper surface of the first protruding portion 270.

[0076] In the example shown in FIGS. 3 and 4, the second limiting surface 290 of the first recessed portion 280 is in abutment with the upper surface of the first protruding portion 270 in the vertical direction Z when the first protruding portion 270 extends into the first recessed portion 280.
