DETAILED DESCRIPTION The present application will be further described in detail below in combination the accompanying drawings and specific embodiments. It should be understood that, the specific embodiments described herein are only used to explain the present application, but not to limit the present application. In the embodiments of the present application, it should be noted that, unless specified or limited otherwise, the term “connected” is used broadly, and may be, for example, electrical connections; may also be inner communications of two elements; may also be direct connections or indirect connections via intervening structures; which can be understood by those skilled in the art according to specific situations. It should be noted that, the terms “first\second\third” involved in the embodiments of the present application are merely used to distinguish similar objects, and do not represent a particular sort of the objects. It should be understood that, particular order and precedence sequence for the terms “first\second\third” can be exchanged if permitted. It should be understood that, the objects distinguished by “first\second\third” can be exchanged under appropriate circumstances, such that the embodiments of the present application described herein can be implemented in orders in addition to those illustrated or described herein. It should be noted that the embodiments in the present disclosure and the features in the embodiments may be combined with each other without conflict. A battery device recited in embodiments of the present application will be described in detail below in combination with FIGS. Ito 4. The battery device includes: a battery pack 110 and a thermal insulator 120. The battery pack 2 Date Re<;ue/Date Received 2023-11-02110 includes a battery and a housing enclosing the battery. The thermal insulator 120 is provided to at least a side of the housing, and the thermal insulator 120 and the housing define a clearance space therebetween. The thermal insulator 120 is exposed to an external environment. The clearance space has an air layer 130 therein. The thermal insulator 120 and the air layer 130 are used to prevent hot air from heating the battery pack 110 when the hot air flows to the thermal insulator 120. Therefore, the thermal insulator 120 and the air layer 130 can prevent the hot air from increasing the temperature of the battery pack 110, improving the performance of the battery device. In embodiments of the present application, the battery pack 110 includes a battery and a housing enclosing the battery. Herein, the structure of the battery is not limited, as long as it can supply electricity to other apparatuses. Herein, the housing is used to protect the battery, and the structure of the housing is not limited, as long as the battery is enclosed. The housing can wrap an outside of the battery and enclose the battery. In embodiments of the present application, the structure of the thermal insulator 120 is not limited, as long as the thermal insulator 120 is provided to at least a side of the housing, and the thermal insulator 120 and the housing define a clearance space therebetween. For example, as illustrated in FIGS. 1 and 4, the thermal insulator 120 may have a plate-like structure. Herein, the thermal insulator 120 can only cover a surface of a side of the battery pack 110. Herein, the clearance space may be a closed space, or a non-closed space. As an example, a periphery of the thermal insulator 120 is sealingly connected to the housing. That is, the clearance space is a closed space such that the thermal insulator 120 and the housing are completely isolated by the closed clearance space, improving the thermal insulation effect of the thermal insulator 120. As another example, the thermal insulator 120 is connected to the housing by a strut. That is, the clearance space is a non-closed space. Herein, an area of the thermal insulator 120 is not limited. The area of the thermal insulator 120 may be equal to an area of a surface of a side of the battery pack 110, or the area of the thermal insulator 120 may also be smaller than the area of the surface of the side of the battery pack 110. As an example, as illustrated in FIG. 2, the area of the thermal insulator 120 is greater than of an area of a surface of a side of the housing, the thermal insulator 120 covers the surface of the side of the 3 Date Re<;ue/Date Received 2023-11-02housing, and an edge of the insulator 120 protrudes from the surface of the housing, to achieve that the thermal insulator 120 fully covers the surface of the side of the housing. When the hot air flows to the thermal insulator 120, the thermal insulator 120 is used to render the hot air to bypass the housing, and make a clearance defined between the hot air and the housing. Thus, contact between the hot air and the battery pack 110 can be effectively prevented. By way of another example, the thermal insulator 120 has an accommodating groove, and at least a part of the battery pack 110 is located in the accommodating groove. Herein, as illustrated in FIG. 3, a first part of the battery pack 110 is located in the accommodating groove, and a second part of the battery pack 110 is located outside the accommodating groove. Certainly, the battery pack 110 may also be wholly located in the accommodating groove. Herein, the thermal insulator 120 covers a plurality of surfaces of the housing. When the hot air flows to the thermal insulator 120, the thermal insulator 120 can reduce the heating of the hot air to the battery pack 110, thereby preventing an excessive temperature of the batteiy pack 110. Herein, the periphery of the thermal insulator 120 may be sealingly connected to the housing. That is, the clearance space is a closed space such that the thermal insulator 120 and the housing are completely isolated by the closed clearance space, improving the thermal insulation effect of the thermal insulator 120. As another example, the thermal insulator 120 is connected to the housing by a strut. That is, the clearance space is a non-closed space. A set position of the thermal insulator 120 is not limited. For example, the thermal insulator 120 may be located at a top side of the battery pack 110. By way of another example, as illustrated in FIGS. 1 to 3, the thermal insulator 120 may also be located at a bottom side of the battery pack 110. By way of yet another example, the thermal insulator 120 may also be located at an edge side of the battery pack 110. The position of the thermal insulator 120 can be flexibly set according to the position of the battery pack 110 relative to a heat source, such as an engine radiator on a vehicle. The implementations of the arrangement of the thermal insulator 120 to the battery pack 110 are not limited. For example, the thermal insulator 120 may be connected to the battery pack 110 by welding to be arranged to the battery pack 110. By way of another example, the thermal insulator 120 may be detachably connected to the battery pack 110 through a snap-fit structure,to be arranged to at least a side of the housing. In the embodiments of the present embodiments, the structure of the clearance space is not 4 Date Re<;ue/Date Received 2023-11-02limited, as long as the clearance space has an air layer 130 therein. Thus, when the hot air passes through the surface of the thermal insulator 120 to heat the thermal insulator 120, the transfer of heat absorbed by thermal insulator 120 to the battery pack 110 can be reduced by the air layer 130. In some optional implementations of the embodiments of the present application, the battery device may further include a fixing member. The fixing member is fixedly connected to the battery pack 110, and the fixing member is used to secure the battery device. The fixing member and the thermal insulator 120 are provided to different positions of the battery pack 110, such that the battery pack 110 is secured to other structures through the fixing member. For example, the battery pack 110 is secured to a frame of a travelling apparatus through the fixing member. In the present implementation, the structure of the fixing member is not limited. For example, the fixing member may be a protruding structure secured to the battery pack 110, the protruding structure is provided with a mounting hole, and the battery pack 110 is secured to other structures through the mounting hole. The battery device in the embodiments of the present application includes: a battery pack 110 and a thermal insulator 120. The battery pack 110 includes a battery and a housing enclosing the battery. The thermal insulator 120 is provided to at least a side of the housing, and the thermal insulator 120 and the housing define a clearance space therebetween. The clearance space has an air layer 130 therein. The thermal insulator 120 and the air layer 130 are used to reduce the heat of the hot air transferred to the battery pack 110 when the hot air flows to the thermal insulator 120. Therefore, the thermal insulator 120 and the air layer 130 can prevent the hot air from increasing the temperature of the battery pack 110, improving the performance of the battery device. Embodiments of the present application further recite a travelling apparatus including the battery device recited in the embodiments of the present application. In the embodiments of the application, the structure of the travelling apparatus is not limited. For example, the travelling apparatus may be an all-terrain vehicle, a beach buggy, and so on. In some optional implementations of the embodiments of the present application, the travelling apparatus may also include a frame and a buffer. The housing is secured to the frame,and the thermal insulator 120 is provided to a bottom side of the housing. The buffer is provided between the thermal insulator 120 and the frame such that damage to the thermal insulator 120 due to collision of the thermal insulator 120 and the frame during traveling of the travelling apparatus can be prevented. In the present implementation, the structure of the frame is not limited. For example, the frame 5 Date Re<;ue/Date Received 2023-11-02may be a frame of an all-terrain vehicle, or may also be a frame of a beach buggy. In the present implementation, as illustrated in FIG. 5, the travelling apparatus may also include a flow guide member 150. The flow guide member 150 is provided to the frame, and the flow guide member 150 is used to guide the hot air to thermal insulator 120. The hot air is guided to the thermal insulator 120 through theflow guide member 150, such that the hot air can be prevented from heating the surfaces of housing without the thermal insulator 120. In some optional implementations of the embodiments of the present application, as illustrated in FIG. 5, the travelling apparatus may further include a fan 140. The fan 140 is provided to the frame, and thefan 140 is used to dissipate heat for a heating member of the travelling apparatus. The battery device is provided in an air guide passage of the fan 140, and the thermal insulator 120 is located at a side of the battery pack in the air guide passage close to the fan 140. When the fan 140 guides the hot air to the thermal insulator 120, the thermal insulator 120 and the air layer 130 are used to prevent the hot air from heating the battery pack 110. Thus, the thermal insulator 120 and the air layer 130 can prevent the hot air from increasing the temperature of the battery pack 110, improving the performance of the battery device. In the present implementation, the structure of the fan 140 is not limited, as long as the fan 140 can dissipate heat for the heating member of the travelling apparatus. For example, the fan 140 may be an axial fan. Herein, the implementations of the arrangement of the fan 140 to the frame are not limited. For example, the fan 140 may be secured to the frame through a bolt. Herein, the structure of the heating member is not limited. For example, the heating member may be a controller, a circuit board, or the like of the travelling apparatus. In the present implementation, the battery device is provided in the air guide passage of the fan 140, and the thermal insulator 120 is located at a side in the air guide passage close to the fan 140. Thus, when the fan 140 guides the hot air to the thermal insulator 120, the thermal insulator 120 and the air layer 130 can prevent the hot air from heating the battery pack 110. In the present implementation, as illustrated in FIG. 5, the flow guide member 150 is provided to the frame, the flow guide member 150 and the thermal insulator 120 are located at different sides of the battery pack 110, and the flow guide member 150 and the housing define a clearance therebetween. The flow guide member 150 is used to prevent the hot air from flowing to the battery pack 110, such that the flow guide member 150 can also prevent the hot air from heating the battery 6 Date Re<;ue/Date Received 2023-11-02pack 110. Herein, the structure of the flow guide member 150 is not limited. For example, the flow guide member 150 may have a plate-like structure. As an example, a projection area of the battery pack 110 in a first direction is located within a projection area of the flow guide member 150 in the first direction. The first direction refers to a flow direction of the hot air from the fan 140 to the flow guide member 150. Thus, the hot air is completely guided to the thermal insulator 120 through the flow guide member 150, and the hot air is prevented from heating the battery pack HOby the thermal insulator 120 and the air layer 130. Herein, the implementations of the arrangement of the flow guide member 150 to the frame are note limited. For example, the flow guide member 150 may be secured to the frame through a bolt. It should be noted that, in FIG. 5, arrow directions at cold air refer to flow directions of the air that does not undergo the heat exchange yet, and arrow directions at the hot air refer to flow directions of the air that has undergone the heat exchange. The above-described are merely specific implementations of the present application, but the protection scope of the present application is not limited to this. The conceivable change or alternative by those skilled in the art within the technical scope disclosed by the present application should be covered in the protection scope of the present application. Therefore, the protection scope of the present application is subject to the protection scope of the claims. Date Re<;ue/Date Received 2023-11-02
