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 <FIG>.

The battery device includes: a battery body <NUM> and a thermal insulator <NUM>. The battery body <NUM> includes a battery and a housing enclosing the battery. The thermal insulator <NUM> is provided to at least a side of the housing, and the thermal insulator <NUM> and the housing define a clearance space therebetween. The clearance space has an air layer <NUM> therein. The thermal insulator <NUM> and the air layer <NUM> are used to prevent hot air from heating the battery body <NUM> when the hot air flows to the thermal insulator <NUM>. Therefore, the thermal insulator <NUM> and the air layer <NUM> can prevent the hot air from increasing the temperature of the battery body <NUM>, improving the performance of the battery device.

In embodiments of the present application, the battery body <NUM> 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 <NUM> is not limited, as long as the thermal insulator <NUM> is provided to at least a side of the housing, and the thermal insulator <NUM> and the housing define a clearance space therebetween.

For example, as illustrated in <FIG> and <FIG>, the thermal insulator <NUM> may have a plate-like structure. Herein, the thermal insulator <NUM> can only cover a surface of a side of the battery body <NUM>.

Herein, the clearance space may be a closed space, or a non-closed space. As an example, a periphery of the thermal insulator <NUM> is sealingly connected to the housing. That is, the clearance space is a closed space such that the thermal insulator <NUM> and the housing are completely isolated by the closed clearance space, improving the thermal insulation effect of the thermal insulator <NUM>. As another example, the thermal insulator <NUM> 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 <NUM> is not limited. The area of the thermal insulator <NUM> may be equal to an area of a surface of a side of the battery body <NUM>, or the area of the thermal insulator <NUM> may also be smaller than the area of the surface of the side of the battery body <NUM>. As an example, as illustrated in <FIG>, the area of the thermal insulator <NUM> is greater than of an area of a surface of a side of the housing, the thermal insulator <NUM> covers the surface of the side of the housing, and an edge of the insulator <NUM> protrudes from the surface of the housing, to achieve that the thermal insulator <NUM> fully covers the surface of the side of the housing. When the hot air flows to the thermal insulator <NUM>, the thermal insulator <NUM> 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 body <NUM> can be effectively prevented.

By way of another example, the thermal insulator <NUM> has an accommodating groove, and at least a part of the battery body <NUM> is located in the accommodating groove.

Herein, as illustrated in <FIG>, a first part of the battery body <NUM> is located in the accommodating groove, and a second part of the battery body <NUM> is located outside the accommodating groove. Certainly, the battery body <NUM> may also be wholly located in the accommodating groove.

Herein, the thermal insulator <NUM> covers a plurality of surfaces of the housing. When the hot air flows to the thermal insulator <NUM>, the thermal insulator <NUM> can reduce the heating of the hot air to the battery body <NUM>, thereby preventing an excessive temperature of the battery body <NUM>.

Herein, the periphery of the thermal insulator <NUM> may be sealingly connected to the housing. That is, the clearance space is a closed space such that the thermal insulator <NUM> and the housing are completely isolated by the closed clearance space, improving the thermal insulation effect of the thermal insulator <NUM>. As another example, the thermal insulator <NUM> 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 <NUM> is not limited. For example, the thermal insulator <NUM> may be located at a top side of the battery body <NUM>. By way of another example, as illustrated in <FIG>, the thermal insulator <NUM> may also be located at a bottom side of the battery body <NUM>. By way of yet another example, the thermal insulator <NUM> may also be located at an edge side of the battery body <NUM>. The position of the thermal insulator <NUM> can be flexibly set according to the position of the battery body <NUM> relative to a heat source, such as an engine radiator on a vehicle.

The implementations of the arrangement of the thermal insulator <NUM> to the battery body <NUM> are not limited. For example, the thermal insulator <NUM> may be connected to the battery body <NUM> by welding to be arranged to the battery body <NUM>. By way of another example, the thermal insulator <NUM> may be detachably connected to the battery body <NUM> 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 limited, as long as the clearance space has an air layer <NUM> therein. Thus, when the hot air passes through the surface of the thermal insulator <NUM> to heat the thermal insulator <NUM>, the transfer of heat absorbed by thermal insulator <NUM> to the battery body <NUM> can be reduced by the air layer <NUM>.

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 body <NUM>, and the fixing member is used to secure the battery device. The fixing member and the thermal insulator <NUM> are provided to different positions of the battery body <NUM>, such that the battery body <NUM> is secured to other structures through the fixing member. For example, the battery body <NUM> 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 body <NUM>, the protruding structure is provided with a mounting hole, and the battery body <NUM> is secured to other structures through the mounting hole.

The battery device in the embodiments of the present application includes: a battery body <NUM> and a thermal insulator <NUM>. The battery body <NUM> includes a battery and a housing enclosing the battery. The thermal insulator <NUM> is provided to at least a side of the housing, and the thermal insulator <NUM> and the housing define a clearance space therebetween. The clearance space has an air layer <NUM> therein. The thermal insulator <NUM> and the air layer <NUM> are used to reduce the heat of the hot air transferred to the battery body <NUM> when the hot air flows to the thermal insulator <NUM>.

Therefore, the thermal insulator <NUM> and the air layer <NUM> can prevent the hot air from increasing the temperature of the battery body <NUM>, 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 <NUM> is provided to a bottom side of the housing. The buffer is provided between the thermal insulator <NUM> and the frame such that damage to the thermal insulator <NUM> due to collision of the thermal insulator <NUM> 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 may 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>, the travelling apparatus may also include a flow guide member <NUM>. The flow guide member <NUM> is provided to the frame, and the flow guide member <NUM> is used to guide the hot air to thermal insulator <NUM>. The hot air is guided to the thermal insulator <NUM> through the flow guide member <NUM>, such that the hot air can be prevented from heating the surfaces of housing without the thermal insulator <NUM>.

In some optional implementations of the embodiments of the present application, as illustrated in <FIG>, the travelling apparatus may further include a fan <NUM>. The fan <NUM> is provided to the frame, and the fan <NUM> 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 <NUM>, and the thermal insulator <NUM> is located at a side of the battery body in the air guide passage close to the fan <NUM>. When the fan <NUM> guides the hot air to the thermal insulator <NUM>, the thermal insulator <NUM> and the air layer <NUM> are used to prevent the hot air from heating the battery body <NUM>. Thus, the thermal insulator <NUM> and the air layer <NUM> can prevent the hot air from increasing the temperature of the battery body <NUM>, improving the performance of the battery device.

In the present implementation, the structure of the fan <NUM> is not limited, as long as the fan <NUM> can dissipate heat for the heating member of the travelling apparatus. For example, the fan <NUM> may be an axial fan.

Herein, the implementations of the arrangement of the fan <NUM> to the frame are not limited. For example, the fan <NUM> 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 <NUM>, and the thermal insulator <NUM> is located at a side in the air guide passage close to the fan <NUM>. Thus, when the fan <NUM> guides the hot air to the thermal insulator <NUM>, the thermal insulator <NUM> and the air layer <NUM> can prevent the hot air from heating the battery body <NUM>.

In the present implementation, as illustrated in <FIG>, the flow guide member <NUM> is provided to the frame, the flow guide member <NUM> and the thermal insulator <NUM> are located at different sides of the battery body.

<NUM>, and the flow guide member <NUM> and the housing define a clearance therebetween. The flow guide member <NUM> is used to prevent the hot air from flowing to the battery body <NUM>, such that the flow guide member <NUM> can also prevent the hot air from heating the battery body <NUM>.

Herein, the structure of the flow guide member <NUM> is not limited. For example, the flow guide member <NUM> may have a plate-like structure. As an example, a projection area of the battery body <NUM> in a first direction is located within a projection area of the flow guide member <NUM> in the first direction. The first direction refers to a flow direction of the hot air from the fan <NUM> to the flow guide member <NUM>. Thus, the hot air is completely guided to the thermal insulator <NUM> through the flow guide member <NUM>, and the hot air is prevented from heating the battery body <NUM> by the thermal insulator <NUM> and the air layer <NUM>.

Herein, the implementations of the arrangement of the flow guide member <NUM> to the frame are note limited. For example, the flow guide member <NUM> may be secured to the frame through a bolt.

It should be noted that, in <FIG>, 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.
