It can be understood that the specific embodiments described herein are merely for explaining the present utility model, rather than limiting the present utility model. Additionally, it should be noted that for the convenience of description, only the parts related to the present utility model are shown in the drawings, rather than all the structures.

[0032] In the description of the present utility model, unless otherwise clearly defined and limited, the terms "connected", "connected to", and "fixed" should be understood in a broad sense.

In addition, the terms "first" and "second" are only used for distinction in description and do not have special meanings.

[0035] This embodiment provides a heating device and an energy storage protection package. The energy storage protection package includes a package body and the above-mentioned heating device. The package body is used to accommodate an energy storage power supply, and the heating device can be installed inside the package body. Among them, the package body is a portable package for accommodating an energy storage power supply, usually having a rectangular package body structure. Its specific structure belongs to the prior art and will not be elaborated here.

[0036] As Figures 1 to 3 shown, the heating device includes a heating component 10. The heating component 10 includes a heating layer 11 and a heat preservation layer 12. The heating layer 11 and the heat preservation layer 12 are stacked. The heating layer 11 includes an electric heating element 111, and the electric heating element 111 is electrically connected to a power supply interface 113. The power supply interface 113 can be electrically connected to the energy storage power supply.

[0037] Specifically, for the heating device provided in this embodiment, the heating device can be installed and used inside a package body for accommodating an energy storage power supply. When the energy storage power supply is accommodated in the package body, it is ensured that the heating layer 11 faces the energy storage power supply, and the heat preservation layer 12 faces away from the energy storage power supply. The electric heating element 111 is electrically connected to the energy storage power supply inside the package body through the power supply interface 113, so that the energy storage power supply can supply power to the electric heating element 111. By the electric heating element 111 generating heat, the temperature inside the package body is increased, so that the energy storage power supply is in a suitable working temperature. Even when the external environment is a low-temperature environment, the energy storage power supply can still be used normally. The heat preservation layer 12 can reduce the heat transfer inside and outside the package body and reduce heat dissipation, playing a heat preservation effect; the heating device can also be separately stored and maintained when not in use, which is convenient and flexible to use. Through the cooperation with the package body, this heating device enables the energy storage protection package to not only meet the function of accommodating the energy storage power supply, but also realize the functions of heat preservation and heating. Even if the energy storage power supply itself does not have a heating and heat preservation structure, it can still ensure that the energy storage power supply can work in a suitable temperature environment.

[0038] Exemplarily, the heating component 10 is at least arranged at the bottom inside the package body. In this embodiment, the heating component 10 is arranged at the bottom inside the package body, and the energy storage power supply can be directly placed on the upper side of the heating component 10. In this way, there is no need to fix the heating component 10. The heating component 10 can be configured as a square, which is adapted to the shape of the bottom of the package body. In other embodiments, the heating component 10 can also be arranged on any one or more of the bottom, top and four side walls of the package body, and no specific limitation is made here.

[0039] In an alternative embodiment, as Figure 3 shown, the heating layer 11 includes an electric heating element 111 and a base material 112 covering the upper and lower surfaces of the electric heating element 111. Among them, the base material 112 can be a PI film, a silicone film or an epoxy film, etc. The electric heating element 111 is a resistance sheet, which has a relatively high internal resistance and can generate heat when powered on. In other embodiments, the electric heating element 111 can also be an electric heating wire.

[0040] In an alternative embodiment, the heat insulation layer 12 can be foam or pearl cotton. These materials such as foam and pearl cotton have low thermal conductivity and high compressibility, can isolate air, play a good heat insulation function, improve the heating efficiency, and at the same time can also provide a certain mechanical buffering effect for the heating layer 11.

[0041] In an alternative embodiment, as Figure 2 and Figure 3 shown, the heating assembly 10 further includes an insulating support layer 13, and the insulating support layer 13 is stacked on the side of the heat insulation layer 12 away from the heating layer 11. It can be understood that the heating layer 11 itself is relatively soft and large in size and is prone to deformation, and the heat insulation layer 12 is also a relatively soft material. By adding the rigid insulating support layer 13, it can provide support for the heating layer 11 and the heat insulation layer 12, ensuring that the entire heating assembly 10 has a certain flatness.

[0042] Exemplarily, the insulating support layer 13 can be an epoxy board or a PC board. The epoxy board and the PC board have certain insulation properties and relatively hard textures, can provide good support for the heating layer 11 and the heat insulation layer 12, and the cost is relatively low.

[0043] In an alternative embodiment, as Figure 2 shown, the heating assembly 10 further includes a first encapsulation cloth layer 14 and a second encapsulation cloth layer 15 which are oppositely arranged. The heating layer 11, the heat insulation layer 12 and the insulating support layer 13 are all located between the first encapsulation cloth layer 14 and the second encapsulation cloth layer 15, and the edges of the first encapsulation cloth layer 14 and the second encapsulation cloth layer 15 are connected to encapsulate the heating layer 11, the heat insulation layer 12 and the insulating support layer 13 inside. Such a setting makes the heating assembly 10 look more beautiful in appearance.

[0044] Exemplarily, the first encapsulation cloth layer 14 and the second encapsulation cloth layer 15 can be made of waterproof cloth material or ordinary woven cloth. Exemplarily, the first encapsulation cloth layer 14 and the second encapsulation cloth layer 15 can be connected by sewing or bonding.

[0045] In an alternative embodiment, as Figure 3 shown, the power supply interface 113 is arranged on the electro-heating element 111. Exemplarily, the power supply interface 113 can be selected from a USB interface, a SATA interface, a D-type large 4Pin interface, a 24Pin interface, etc., and no specific limitation is made here.

[0046] In an alternative embodiment, as Figure 3 and Figure 4As shown, the heating component 10 further includes a first temperature acquisition module 16 and a thermostat 17. The first temperature acquisition module 16 is disposed on the electric heating element 111 and is used to detect and collect the surface temperature of the electric heating element 111. The thermostat 17 is communicatively connected to the first temperature acquisition module 16 and is used to control the on / off of the electric heating element 111. The first temperature acquisition module 16 detects the surface temperature of the electric heating element 111 in real time through a temperature sensor. The thermostat 17 controls the start and stop of the electric heating element 111 according to the magnitude relationship between the measured temperature of the first temperature acquisition module 16 and the preset temperature value, preventing the electric heating element 111 from overheating and ensuring safety. Exemplarily, when the measured temperature of the first temperature acquisition module 16 reaches the first preset temperature value, the thermostat 17 controls the electric heating element 111 to stop heating, thereby preventing overheating. Among them, the first preset temperature can be 70 degrees.

[0047] In an alternative embodiment, as Figure 3 shown, three accommodation holes 121 are formed in the heat preservation layer 12. The positions of the three accommodation holes 121 respectively correspond to the first temperature acquisition module 16, the thermostat 17, and the power supply interface 113. The first temperature acquisition module 16, the thermostat 17, and the power supply interface 113 are respectively embedded in the corresponding accommodation holes 121, so as to ensure that the surface of the heating component 10 has no protrusions, and further prevent the protrusions from piercing the heating component 10 when the energy storage power supply presses on the surface of the heating component 10.

[0048] Furthermore, as Figure 1 shown, the heating device further includes a lead wire 20 and a control box 30. The power supply interface 113 is electrically connected to the energy storage power supply through the lead wire 20. The free end of the lead wire 20 can be a USB interface 23, and is electrically connected to the energy storage power supply through the USB interface 23. The control box 30 is electrically connected to the lead wire 20. A second temperature acquisition module is provided in the control box 30. The second temperature acquisition module is communicatively connected to the thermostat 17 and is used to detect the ambient temperature inside the package. The thermostat 17 can also control the start and stop of the electric heating element 111 according to the magnitude relationship between the measured temperature of the second temperature acquisition module and the preset temperature value, preventing heating from still being carried out in the case of too high ambient temperature and avoiding the energy storage power supply being at a high temperature.

[0049] Exemplarily, when the measured temperature of the second temperature collection module reaches the second preset temperature value, the thermostat 17 controls the electric heating element 111 to stop heating, thereby preventing heating when the ambient temperature is too high. Among them, the second preset temperature is less than the first preset temperature, and the second preset temperature can be 25 degrees. That is to say, when the measured temperature of the first temperature collection module 16 is less than the first preset temperature value and the measured temperature of the second temperature collection module is less than the second preset temperature value, the electric heating element 111 remains in the powered heating state. When the measured temperature of either the first temperature collection module 16 or the second temperature collection module reaches the corresponding preset temperature, the thermostat 17 controls the electric heating element 111 to stop heating. In this way, by simultaneously monitoring the ambient temperature and the temperature of the electric heating element 111 itself, the purpose of intelligent temperature control is achieved, preventing the electric heating element 111 from overheating and preventing heating when the ambient temperature is too high, and avoiding thermal runaway of the energy storage power supply in a high-temperature environment.

[0050] Specifically, as Figure 1 shown, the control box 30 divides the lead wire 20 into a first section 21 and a second section 22. The first section 21 is located between the control box 30 and the power supply interface 113, and the second section 22 is located between the control box 30 and the energy storage power supply. The length of the first section 21 is greater than the length of the second section 22. Such a setting can make the position of the control box 30 far from the electric heating element 111, ensure that the temperature collected by the second collection module is closer to the actual ambient temperature, and reduce the influence of the electric heating element 111 on the second collection module.

[0051] Specifically, as Figure 5 and Figure 6 shown, the control box 30 includes a housing. The housing is a plastic shell, which includes an upper cover 31 and a lower shell 32. The upper cover 31 and the lower shell 32 are buckled together to form a receiving cavity. A PCB board 33 is arranged in the receiving cavity. Two indicator lights 35 are electrically connected to the PCB board 33, respectively indicating the powered-on and heating states. The colors of the two indicator lights 35 can be different. For example, a red light indicates powered-on and a green light indicates heating. A switch 34 is arranged on the side of the housing. The switch 34 is electrically connected to the PCB board 33. By manually toggling the switch 34, the on / off of the electric heating element 111 can be controlled. The two ends of the housing along its length direction are respectively connected with an upper wire outlet part 36 and a lower wire outlet part 37. After the first section 21 of the lead wire 20 is electrically connected to the PCB board 33, it is led out through the upper wire outlet part 36. After the second section 22 of the lead wire 20 is electrically connected to the PCB board 33, it is led out through the lower wire outlet part 37. Among them, the second temperature collection module can be a PCB board 33 integrated with a temperature sensor.

[0052] It should be noted that the above-mentioned electric heating element 111, power supply interface 113, first temperature acquisition module 16, temperature controller 17, and second temperature acquisition module are all prior arts, which can be fully realized by those skilled in the art without further elaboration. The internal electrical connection structure is also well-known to those skilled in the art. Any electrical connection structure in the prior art that can achieve the above effects can be adopted in this application, and no further description will be given here. The content protected by this utility model does not involve the improvement of software either.

[0053] Obviously, the above embodiments of the present utility model are merely examples for clearly explaining the present utility model, rather than limiting the implementation manners of the present utility model. For those of ordinary skill in the art, various obvious changes, re-adjustments and substitutions can be made without departing from the protection scope of the present utility model. It is not necessary and impossible to enumerate all the implementation manners here.
