[0025] It should be noted that, unless otherwise specified, the technical terms or scientific terms used in this application should have the common meanings understood by technicians in the field to which this application belongs.

[0026] In existing computer equipment, the battery temperature is adjusted by adding fans and other devices. This structure increases the operating burden of the CPU. The inventor wants to design a device that uses the adaptive deformation ability of the material itself to adjust the battery temperature. This does not require the participation of CPU and other devices and does not increase the system computing burden.

[0027] Embodiment 1

[0028] Reference Figure 1 -Attached Figure 3 Embodiment 1 of the present invention proposes an electronic device, which includes: a shell 1, a battery module 2, a heating module 3 and a heat-conducting structure 4, wherein the shell 1 has a containing space 11 and two first shell walls 12 opposite to each other in a first direction A; the battery module 2 and the heating module 3 are arranged in the containing space 11 at intervals; the heat-conducting structure 4 is movably arranged in the containing space 11, and includes a first part 41 corresponding to the battery module 2 and a second part 42 corresponding to the heating module 3, the second part 42 is in contact with the heating module 3 and can conduct heat, and the heat-conducting structure 4 can switch between a first state and a second state; when the heat-conducting structure 4 is in the first state, the first part 41 is in contact with the battery module 2; when the heat-conducting structure 4 is in the second state, the first part 41 is not in contact with the battery module 2.

[0029] Specifically, the electronic device provided in this embodiment can be, but is not limited to, a laptop, a server, a computer, etc. The housing 1 is a shell structure of the electronic device, which includes two first shell walls 12 opposite to each other in a first direction A; a heating module 3 and a battery module 2 are arranged in the housing 1, and the heating module 3 specifically includes, but is not limited to, a CPU, and can also include a graphics card, a memory stick, etc. The battery module 2 is used to power the electronic device. The heat-conducting structure 4 is made of a heat-conducting material, and includes a first part corresponding to the battery module 2 and a second part corresponding to the heating module 3, and the heat-conducting structure 4 can switch between the first state and the second state by its own deformation or other mechanical deformation structures 5. Here, an example is given of the heat-conducting structure switching its state by its own deformation, such as: when the temperature is low, its volume becomes large so that the first part 41 of the heat-conducting structure 4 contacts the battery module 2, and at this time, the heat of the heating module 3 can be transferred to the battery module 2, and when the temperature is high, its volume shrinks so that the first part 41 of the heat-conducting structure 4 is away from the battery module 2, and at this time, the heat of the heating module 3 will not be transferred to the battery module 2.

[0030] According to the above, the embodiment of the utility model proposes an electronic device, which uses different states of the heat-conducting structure 4 to adjust the temperature of the battery module 2. When the temperature of the battery module 2 is too low, the heat-conducting structure 4 is in the first state, at which time the heat-conducting structure 4 contacts the battery module 2 and the heating module 3 and transfers the heat of the heating module 3 to the battery module 2. When the temperature of the battery module 2 is too high, the heat-conducting structure 4 is in the second state, at which time the heat-conducting structure 4 does not contact the battery module 2 and does not transfer the heat of the heating module 3 to the battery module 2. The electronic device can automatically adjust the battery temperature, ensure that the battery is always within the normal working temperature range, and solve the problem that the lithium battery temperature is too high or too low and affects the cycle life of the battery.

[0031] For further information, see Attachment Figure 1 -Attached Figure 3 In a specific implementation, when the temperature of the area where the battery module 2 is located is lower than a first threshold, the heat-conducting structure 4 is in a first state; when the temperature of the area where the battery module 2 is located is higher than a second threshold, the heat-conducting structure 4 is in a second state.

[0032] Specifically, in order to realize that the heat-conducting structure 4 automatically adjusts the temperature of the battery module 2, the technical solution adopted by the utility model sets a first threshold and a second threshold. The specific sizes of the first threshold and the second threshold are not limited here, and can be set according to the performance of the battery. The second threshold is higher than the first threshold. When the temperature of the area where the battery module 2 is located is lower than the first threshold, the heat-conducting structure 4 is in the first state, that is, the first part 41 of the heat-conducting structure 4 is in contact with the battery module 2 (such as the attached Figure 2 When the temperature of the area where the battery module 2 is located is higher than the second threshold, the heat-conducting structure 4 is in the second state, that is, the first portion 41 of the heat-conducting structure 4 is not in contact with the battery module 2 (as shown in the attached Figure 3 When the temperature of the area where the battery module 2 is located is between the first threshold and the second threshold, the first portion 41 may contact the battery module 2 (as shown in the attached Figure 1 As shown), but in this temperature range, the area and / or degree of contact between the first portion 41 and the battery module 2 is smaller than the area of ​​contact between the first portion and the battery module 2 when the temperature of the region is lower than the first threshold.

[0033] For further information, see Attachment Figure 1 -Attached Figure 3 In a specific implementation, the heat-conducting structure 4 switches between the first state and the second state through its own deformation.

[0034] Specifically, in order to realize that the heat-conducting structure 4 automatically selects to conduct heat to the battery module 2 according to the temperature change, in the technical solution adopted by the utility model, the heat-conducting structure 4 is used to generate its own deformation according to the temperature change to realize its switching between the first state and the second state. The heat-conducting structure 4 can be connected to the first shell wall 12 through a connecting piece, and the first part 41 and the second part 42 are integrally formed and are both memory metal materials. When the regional temperature of the battery module 2 is low, the first part 41 and the second part 42 of the heat-conducting structure 4 are deformed and the volume increases, so that the first part 41 contacts the battery module 2 and the second part 42 contacts the heating module 3; when the regional temperature of the battery module 2 is high, the first part 41 and the second part 42 of the heat-conducting structure 4 are deformed and the volume decreases, so that the first part 41 does not contact the battery module 2 and the second part 42 contacts the heating module 3. In addition, the thickness of the second part 42 can be set to be greater than the thickness of the first part 41 so that when the heat-conducting structure 4 is in the second state, the heat-conducting structure 4 is deformed and the volume is reduced, so that the second part 42 contacts the heating module 3 while the thickness of the first part 41 is not enough to make the first part 41 contact the battery module 2.

[0035] For further information, see Attachment Figure 1 -Attached Figure 3 In a specific implementation, the electronic device also includes at least one deformable structure 5, which is arranged in the accommodating space 11, one end of which is connected to the first shell wall 12, and the other end is connected to the first part 41 of the heat-conducting structure 4, and the deformation direction of the deformable structure 5 is the same as the first direction A; when the deformable structure 5 produces positive deformation along the first direction A, the heat-conducting structure 4 is in a first state; when the deformable structure 5 produces reverse deformation along the first direction A, the heat-conducting structure 4 is in a second state.

[0036] Specifically, in order to realize that the heat-conducting structure 4 automatically selects to conduct heat to the battery module 2 according to the temperature change, in the technical solution adopted by the utility model, a deformation structure 5 is arranged between the first part 41 of the heat-conducting structure 4 and the first shell 1, and the deformation structure 5 can produce its own deformation according to the temperature change, or the deformation structure 5 can be a mechanical deformation material, such as: an electric telescopic rod. The second part 42 is in contact with the heating module 3 when the heat-conducting structure 4 is in the first state and the second state. When the temperature is too low, the deformation structure 5 produces positive deformation along the first direction A, and the first part 41 of the heat-conducting structure 4 contacts the battery module 2, transferring the heat of the heating module 3 to the battery module 2; when the temperature is too high, the deformation structure 5 produces reverse deformation along the first direction A, the first part 41 of the heat-conducting structure 4 does not contact the battery module 2, the first part 41 of the heat-conducting structure 4 is far away from the battery module 2, and the heat-conducting structure 4 cannot transfer the heat of the heating module 3 to the battery module 2. In addition, the number of the deformable structures 5 can be set according to actual needs, and the shape of the deformable structure 5 can be any shape, such as a cylinder, a cuboid, or other shapes, which are not specifically limited here.

[0037] For further information, see Attachment Figure 1 In a specific implementation, the deformation structure 5 is made of a temperature-controlled deformation material.

[0038] Specifically, in order to realize that the deformation structure 5 changes according to temperature, in the technical solution adopted by the present invention, the deformation structure 5 specifically adopts a temperature-controlled deformation material, which can undergo positive deformation or reverse deformation according to the temperature in the area of ​​the battery module 2 to control the contact state between the first part 41 of the heat conductive structure 4 and the battery module 2.

[0039] For further information, see Attachment Figure 1 In a specific implementation, the parts of the battery module 2 and the heating module 3 that are respectively used to contact the heat-conducting structure 4 are respectively provided with heat-conducting materials 6, and the heat-conducting materials 6 are flexible; or the first part 41 and the second part 42 of the heat-conducting structure 4 and the side facing the battery module 2 and the heating module 3 are respectively provided with heat-conducting materials 6, and the heat-conducting materials 6 are flexible.

[0040] Specifically, in order to make the first part 41, the second part 42 fully contact with the battery module 2 and the heating module 3 and to avoid rigid collision between the first part 41, the second part 42 and the battery module 2 and the heating module, in the technical solution adopted by the utility model, a thermal conductive material 6 is respectively arranged between the battery module 2 and the heat-conducting structure 4, and between the heating module 3 and the heat-conducting structure 4. The thermal conductive material 6 can specifically be a material such as thermal conductive foam. The thermal conductive material 6 can be fixed on the battery module 2 and the heating module 3, and can also be fixed on the first part 41 and the second part 42 of the heat-conducting structure 4. No specific limitation is made here.

[0041] For further information, see Attachment Figure 1 In a specific implementation, the electronic device also includes a controller, which is arranged in the accommodating space 11, and is used to obtain the temperature of the battery module 2, and is used to control the system of the electronic device to switch from the first mode to the second mode when the temperature of the battery module 2 is lower than the third threshold or higher than the fourth threshold, and the power consumption of the electronic device in the second mode is less than the power consumption in the first mode; wherein the third threshold is lower than the first threshold, and the fourth threshold is higher than the second threshold.

[0042] Specifically, in order to prevent the electronic device from being damaged due to the overly high or low temperature of the battery module 2, the technical solution adopted by the utility model further includes a controller, which is connected to the battery management chip signal inside the battery module 2 to obtain the temperature of the battery, and the signal connection here can be a wireless connection or a wired connection. When the temperature of the battery module 2 is lower than the third threshold or higher than the fourth threshold, the controller controls the battery module 2 to switch from the first mode to the second mode, where the third threshold is lower than the first threshold, and the fourth threshold is higher than the second threshold. The first mode is the power-on state, and the second mode is the power-off state or the standby state. Such a design is conducive to extending the service life of the electronic device and the battery module.

[0043] For further information, see Attachment Figure 1 and attached Figure 2 In a specific implementation, when the temperature of the battery module 2 is higher than the second threshold, one end of the first portion 41 of the heat-conducting structure 4 contacts the first shell wall 12 and conducts heat.

[0044] Specifically, in order to dissipate the heat of the heat-conducting module 3, in the technical solution adopted by the present invention, when the temperature of the battery module 2 is higher than the second threshold, one end of the first part 41 of the heat-conducting structure 4 is in contact with the first shell wall 12 and transfers the heat of the heat-generating module 3 to the shell 1, and the first part 41 does not contact the battery module 2 to prevent the temperature of the battery module 2 from being too high.

[0045] For further information, see Attachment Figure 1 In a specific implementation, the number of the heat-conducting structures 4 is two, and they are respectively located on both sides of the battery module 2 and the heat-generating module 3 facing the two first shell walls 12 .

[0046] Specifically, in order to quickly transfer the heat of the heating module 3 to the battery module 2 or to quickly transfer the heat of the heating module 3 to the shell 1, in the technical solution adopted by the utility model, the number of heat-conducting structures 4 can be multiple.

[0048] Specifically, in the technical solution adopted by the present invention, when the temperature of the battery module 2 is lower than the first threshold, refer to the attached Figure 1 The contact area between the heat-conducting structure 4 and the battery module 2 can be equal to the contact area between the heat-conducting structure 4 and the heating module 3, or in order to quickly heat it up, refer to the attached Figure 2 The contact area between the heat-conducting structure 4 and the battery module 2 can be larger than the contact area between the heat-conducting structure 4 and the heating module 3 , so as to fully transfer the heat of the heat-conducting structure 4 to the battery module 2 .
