Detailed Description

In order to make the objects, technical solutions and advantages of the present application more clear, embodiments of the present application will be described in further detail below with reference to the accompanying drawings.

When the following description refers to the accompanying drawings, like numbers in different drawings represent the same or similar elements unless otherwise indicated. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present application. Rather, they are merely examples of apparatus and laser emitting assemblies consistent with certain aspects of the present application, as detailed in the appended claims.

Referring to fig. 1 to 8, an embodiment of the present application provides a protective case 100 of an electronic device 200, including a housing 110 and a peltier element 120. The electronic device 200 may be a smartphone, a wearable device, a computing device, a television, a vehicle, a camera, a monitoring device, or the like.

The housing 110 may have any structure having the receiving section 111. The accommodating section 111 is used for accommodating the electronic device 200. Of course, in order to prevent the display, shooting, charging, and other functions of the electronic device 200 from being affected after being wrapped by the housing 110, an opening may be provided in the housing 110. The opening may include a first sub-opening corresponding to a display screen of the electronic device 200 to enable images displayed by the electronic device 200 to be displayed through the first sub-opening for viewing by a user; and enabling a user to operate the electronic device 200 through the first sub-opening. The openings may further include a second sub-opening corresponding to a camera of the electronic apparatus 200, a third sub-opening corresponding to a charging interface of the electronic apparatus 200, a fourth sub-opening corresponding to a power key of the electronic apparatus 200, and the like.

The protection case 100 in the related art generally only has an effect of preventing the surface of the electronic device 200 from being scratched or damaged, and the function is relatively single, and for this reason, the peltier element 120 is additionally arranged on the protection case 100 in the embodiment of the present application, so that the protection case 100 also has an effect of cooling the electronic device 200. After the protective shell 100 is sleeved on the electronic device 200, the heat dissipation of the electronic device 200 is difficult, the heat dissipation can not affect the response speed of the electronic device 200, the user experience is affected, and the problem is well solved after the peltier element 120 is additionally arranged.

The peltier element 120 has a simple structure and is convenient to install, and can achieve the purpose of cooling or heating only by controlling the conduction of the peltier element, so that the control is convenient. Specifically, the peltier element 120 is mounted to the housing 110, and referring to fig. 1 and 2, the peltier element 120 includes two working surfaces which are oppositely disposed and defined as a first surface 121 and a second surface 122 for distinguishing, wherein the first surface 121 may be a surface close to the accommodating section 111, and the second surface 122 may be a surface far from the accommodating section 111. The peltier element 120 further includes a first electrical interface and a second electrical interface, and the peltier element 120 is configured to conduct and conduct current from the first electrical interface to the second electrical interface, so that the first surface 121 becomes a cooling surface and the second surface 122 becomes a heating surface.

The energy source of the peltier element 120 may be the electronic device 200. Of course, to avoid using a limited amount of power of the electronic device 200, the protective case 100 may further include a power supply module 130 for supplying power to the peltier element 120, and the power supply module 130 is electrically connected to the peltier element 120. To facilitate control of the start and stop of the peltier element 120, the protective case 100 may further comprise a first switch 140. The first switch 140 is electrically connected between the power supply module 130 and the peltier element 120, and the first switch 140 is used for controlling on/off of the electrical connection between the power supply module 130 and the peltier element 120.

The first switch 140 may be a mechanical switch that is manually controlled to open and close by a user. Of course, in order to improve the intelligence of the protective case 100, when the temperature of the case 110 is higher than the first predetermined value, the first switch 140 can be automatically closed, so that the first surface 121 of the peltier element 120 becomes a cooling surface to cool the case 110, and the first switch 140 may also be an electronic switch. When the first switch 140 is an electronic switch, the protective case 100 may further include a temperature detector and a first controller in order to detect the temperature of the case 110 and control the on/off of the peltier element 120. The temperature detector is mounted to the housing 110. The first controller is electrically connected to the first switch 140 and the temperature detector, and the first controller is configured to control the peltier element 120 to be turned on when the temperature of the housing 110 is lower than a first predetermined value, and to enable the on-state current of the peltier element 120 to flow from the first electrical interface to the second electrical interface.

The charging performance of the electronic device 100 is greatly reduced when the temperature is low, and the protective case 100 may have a temperature rise function to avoid this phenomenon. The temperature raising function of the protective case 100 can be realized by the peltier element 120, and in this case, the peltier element 120 is further configured to be conductive and to conduct current from the second electrical interface to the first electrical interface, so that the first surface 121 becomes a heating surface and the second surface 122 becomes a cooling surface. The switching of the on current of the peltier element 120 may be realized by a double-pole double-throw switch. The double pole double throw switch can be controlled directly by the user; for example, in cold weather, the double-pole double-throw switch may be adjusted to enable the peltier device 120 to conduct current from the second electrical interface to the first electrical interface when conducting; in hot weather, the double-pole double-throw switch can be adjusted to enable the peltier device 120 to conduct current from the first electrical interface to the second electrical interface when the peltier device is turned on.

To facilitate intelligent control of the temperature rise of the protection casing 100, the first controller may be further configured to control the peltier element 120 to be turned on when the temperature of the casing 110 is lower than a second predetermined value, and to enable the on-state current of the peltier element 120 to flow from the second electrical interface to the first electrical interface, so that the first surface 121 becomes a heating surface and the second surface 122 becomes a cooling surface. Wherein the second predetermined value is smaller than the first predetermined value.

The power supply module 130 may supply power to the electronic device 200 in addition to the peltier element 120. The manner in which the power supply module 130 supplies power to the electronic device 200 may be arbitrary. Of course, in order to simplify the installation between the protective case 100 and the electronic device 200, the power supply module 130 is preferably a wireless power supply for supplying power to the electronic device 200. By setting the power supply module 130 to supply power to the electronic device 200 in a wireless manner, steps such as wiring are omitted, so that the protective case 100 of the embodiment of the application is mounted on the electronic device 200 in the same manner as the protective case 100 and the electronic device 200 in the related art, and the mounting is convenient.

The power supply module 130 can be used as a charging platform for supplying the power of the external power source to the peltier element 120 and the electronic device 200. The power supply module 130 may be used as a power supply to directly supply internal power to the peltier element 120 and the electronic device 200. When the power supply module 130 is used as a power supply platform, the power supply module 130 further includes a first electrical connector, so that the power supply module 130 can be electrically connected to an external power source.

The wireless power supply method between the power supply module 130 and the electronic device 200 may be an electromagnetic induction method, a magnetic field resonance method, a radio wave method, or an electric field coupling method. The following description will take the power supply module 130 to supply power to the electronic device 200 in an electromagnetic induction manner as an example:

when the power supply module 130 is used as a charging platform, referring to fig. 7, the power supply module 130 includes a transmitting coil and a first electrical connector. The transmitting coil is mounted on the housing 110 and is adapted to the power receiving coil 210 of the electronic device 200. The first electrical connector is used to electrically connect the transmitting coil with an external power source, so that the transmitting coil can be conducted, and thus the power is supplied to the power receiving coil 210 in a wireless manner. For convenience of arrangement, a third groove may be disposed on the housing 110, and the first electrical connector can be received in the third groove.

When the power supply module 130 serves as a power supply, referring to fig. 3, 4 and 8, the power supply module 130 includes a transmitting coil 131 and an energy storage unit 133. The transmission coil 131 is mounted on the housing 110, and the transmission coil 131 is fitted to the power receiving coil 210 of the electronic apparatus 200. The energy storage unit 133 is mounted on the housing 110, and the energy storage unit 133 is electrically connected to the transmitting coil 131, so that the transmitting coil 131 can be conducted, and power is supplied to the receiving coil 210 in a wireless manner. In order to avoid the power loss of the energy storage unit 133 caused by the power module 130 continuously supplying power to the electronic device 200, the power module 130 may further include a second switch 134. The second switch 134 is electrically connected between the energy storage unit 133 and the transmitting coil 131, and the second switch 134 is used for controlling the on/off of the electrical connection between the energy storage unit 133 and the transmitting coil 131.

The energy storage unit 133 may be a disposable battery; such as a dry cell battery. When the energy storage unit 133 is a disposable battery, after the electric quantity of the energy storage unit 133 is exhausted, the energy storage unit 133 needs to be replaced with a new one, so that the disassembly and assembly process is complicated, and the abandoned energy storage unit 133 pollutes the environment, so that the energy storage unit 133 can also be a rechargeable battery capable of being recycled. Such as a lithium ion battery, a lithium ion polymer battery, or a nickel metal hydride battery. When the energy storage unit 133 is a rechargeable battery, referring to fig. 4 and 5, the power supply module 130 may also include a first electrical connector 132. At this time, the first electrical connector 132 is used to electrically connect the energy storage unit 133 with an external power source, so that the energy storage unit 133 can be powered by the external power source after the electric quantity of the energy storage unit 133 is exhausted. For convenience of arrangement, the housing 110 may be provided with a third recess 114, and the first electrical connector 132 may be received in the third recess 114.

By providing the function of wirelessly supplying power to the electronic device 200 on the protective case 100, since the structure of the protective case 100 is adapted to the structure of the electronic device 200, and after the electronic device 200 is accommodated in the protective case 100, the corresponding relationship between the electronic device 200 and the protective case 100 is fixed, when the protective case 100 is produced, the transmitting coil 131 can be aligned with the power receiving coil 210 only by ensuring that the installation position of the transmitting coil 131 on the protective case 100 corresponds to the installation position of the power receiving coil 210 on the electronic device 200, thereby ensuring the effectiveness of wireless power supply.

Of course, in order to avoid that the power supply module 130 cannot wirelessly supply power to the electronic device 200 any more when the transmitting coil 131 or the like fails, the protective case 100 according to the embodiment of the present disclosure may further have a wired power supply function. When the protective case 100 has a wired power supply function, the power supply module 130 may further include a second electrical connector for electrically connecting the energy storage unit 133 with the electronic device 200. To simplify the structure of the protective case 100 and reduce the cost, the control module is added to enable the first electrical connector 132 to be used as a second electrical connector without adding a second electrical connector.

Referring to fig. 9, the control module may include a switching power supply control chip U, a transistor Q, and a second controller. The voltage output pin LX of the switching power supply control chip U is electrically connected to the energy storage unit 133, and the enable pin EN of the switching power supply control chip U is electrically connected to the collector of the transistor Q. The emitting electrode of the triode Q is grounded, and the base electrode of the triode Q is electrically connected with the signal adjusting end of the second controller. The first electrical connector 132 is electrically connected between the voltage output pin LX and the energy storage unit 133, and the first electrical connector 132 is further electrically connected to the signal detection end of the second controller. The signal detecting terminal of the second controller can detect whether the first electrical connector 132 is electrically connected to the external power source. When the signal detection end detects that the first electrical connection member 132 is electrically connected with the external power supply, the signal of the signal adjustment end becomes high, and the signal of the enabling pin of the switching power supply control chip U becomes low due to the existence of the triode Q, so that the switching power supply control chip U is disconnected, and the external power supply can supply power to the energy storage unit 133. When the signal detecting terminal does not detect that the first electrical connecting element 132 is electrically connected to the external power supply, the signal of the signal adjusting terminal becomes low, and the signal of the enabling pin of the switching power supply control chip U becomes high due to the existence of the triode Q, so that the power supply control chip is in a working state, and the energy storage unit 133 and the first electrical connecting element 132 output voltage to the outside to supply power to the electronic device 200. In the embodiment of the present application, when the signal detecting end of the second controller detects whether the first electrical connecting element 132 is connected to another device or in a charging state or a discharging state, the signal detecting end further determines by adding a button to the second controller. For example, when the first electrical connector 132 is not electrically connected to the external power source, the button can be pressed to pull down the signal of the signal adjusting terminal.

The housing 110 may include a back plate 112 and a clamping plate 113. The clamping plate 113 is located at the periphery of the back plate 112 and connected to the back plate 112, and the back plate 112 and the clamping plate 113 together form an accommodating space 111. When the electronic device 200 is accommodated in the protective case 100, the back plate 112 is a portion of the protective case 100 corresponding to a rear cover of the electronic device 200, and the clamping plate 113 is a portion of the protective case 100 corresponding to a rim of the electronic device 200. The peltier element 120 may be mounted to the clamping plate 113. Of course, the back plate 112 has a large area, and therefore, the peltier element 120 is preferably mounted to the back plate 112 for easy mounting.

The peltier element 120 may be directly mounted on one surface of the back plate 112 by means of bonding, bolting, or the like. When the peltier element 120 is directly mounted on one surface of the back plate 112, the thickness of the back plate 112 can be made as thin as possible to reduce the volume and weight of the protective case 100 for the user to hold. Of course, in order to mount the peltier element 120 on the back plate 112 firmly, the thickness of the back plate 112 may be made thicker, so that the first groove 1121 for mounting the peltier element 120 can be formed on the back plate 112. The peltier element 120 may be mounted within the first recess 1121 by a snap-fit and/or adhesive means. To avoid the peltier element 120 from being worn and to reduce the thickness of the back plate 112 as much as possible, the depth dimension of the first recess 1121 may be equal to the thickness dimension of the peltier element 120 so that the peltier element 120 can be completely accommodated in the first recess 1121.

The back plate 112 may be a plate body having a uniform thickness. Of course, in order to reduce the weight of the back plate 112 as much as possible, the back plate 112 may include a mounting portion 1122 and a connecting portion 1123 located on the outer periphery of the mounting portion 1122. The thickness dimension of the connecting portion 1123 may be smaller than the thickness dimension of the mounting portion 1122, and the connecting portion 1123 is used for connecting the mounting portion 1122 and the clamping plate 113. The mounting portion 1122 is used to form a first recess 1121 for mounting the peltier element 120 and a third recess 114 for receiving the first electrical connector 132.

In order to provide the energy storage unit 133 with a sufficient amount of stored energy, the volume of the energy storage unit 133 may be relatively large, and the occupied area of the energy storage unit 133 on the protective case 100 may be large, and for this reason, the connection portion 1123 may further have a fourth recess 1125 for mounting the energy storage unit 133.

Referring to fig. 1 and 3, the chucking plate 113 may be a frame plate; that is, the clamping plate 113 includes four plate bodies sequentially enclosed to wrap the frame of the electronic device 200. Of course, when the electronic device 200 such as a mobile phone adopts a curved screen design, in order to prevent the clamping plate 113 from obstructing the normal display and use of the display screen, referring to fig. 6, the clamping plate 113 may also include only two plate bodies, and the two plate bodies correspond to the frame portion of the electronic device 200 where the curved screen is not disposed.

To avoid the cooling function of the protective casing 100 being disabled after the peltier element 120 has failed, the protective casing 100 may further comprise other heat sinks 150. The heat sink 150 is mounted to the housing 110 for dissipating heat from the electronic apparatus 200.

The driving force of the heat sink 150 may be self-generated heat or electric energy. When the driving force of the heat dissipating member 150 is the heat generated by itself, the heat dissipating member 150 may be a super heat conducting copper pipe, the liquid is filled inside the super heat conducting copper pipe, one end of the super heat conducting copper pipe is an evaporation section, and the other end of the super heat conducting copper pipe is a condensation section. The liquid filled in the super heat conduction copper pipe can be water. The super heat conducting copper pipe is installed on the casing 110, and the evaporation section is located at a side close to the accommodating section 111, and the condensation section is located at a side far away from the accommodating section 111. The heat that electronic equipment 200 during operation produced can conduct to the evaporation zone, the evaporation zone receives behind the heat energy and converts inside liquid into vapor, because the evaporation zone is the hot junction, the condensation zone is the cold junction, therefore, vapor can move towards the condensation zone, vapor can carry out the condensation speed of heat exchange acceleration vapor with the outside air after arriving the condensation zone, make vapor condensation become liquid again, this liquid will flow back to the evaporation zone through the capillary strength of superconductive hot copper pipe inner wall, so absorb heat repeatedly, the circulation of condensation can give off electronic equipment 200's heat to the environment in.

When the driving force of heat dissipation element 150 is electric energy, heat dissipation element 150 may include water tank, first pipeline, water pump, second pipeline, cooling tube and the third pipeline that communicate in proper order end to end, and first pipeline, second pipeline and third pipeline all may be located and be close to the one side that holds interval 111, and the cooling tube is located and keeps away from the one side that holds interval 111. The heat that electronic equipment 200 during operation produced can conduct to first pipeline, second pipeline and third pipeline, starts the water pump and can make the water in the water tank circulate and flow between pipeline, cooling tube, can carry out the heat exchange cooling with the outside air when water passes through the cooling tube to reduce the temperature of the water that flows into in the pipeline, realize electronic equipment 200's heat dissipation. Certainly, in order to accelerate the heat dissipation effect of the heat dissipation pipe, fins can be arranged outside the heat dissipation pipe to increase the heat dissipation area.

When the driving force of the heat sink 150 is electric energy, the heat sink 150 may also be a heat dissipation fan, and the heat dissipation fan is installed in the housing 110 to discharge heat generated by the electronic device 200 into the air. In order to prevent the heat dissipation fan from injuring the user during the high-speed operation, the protective case 100 may further include a mesh enclosure located outside the heat dissipation member 150.

When the driving force of the heat sink 150 is electric energy, the energy source of the heat sink 150 may be the electronic apparatus 200. Of course, in order to simplify the structure of the protective case 100, simplify the installation process, and avoid using a limited amount of power of the electronic device 200, the energy source of the heat sink 150 may also be the power supply module 130. That is, the power supply module 130 is further electrically connected to the heat sink 150 to supply power to the heat sink 150. To facilitate controlling the start and stop of the heat sink 150, the protective case 100 may further include a third switch. The third switch is electrically connected between the power supply module 130 and the heat sink 150, and the third switch is used for controlling the on/off of the electrical connection between the power supply module 130 and the heat sink 150.

In order to prevent the heat sink 150 from being disposed to increase the thickness of the protective case 100, a second groove 1124 for receiving the heat sink 150 may be further formed on the back plate 112. To further prevent the thickness of the protective case 100 from increasing, a second groove 1124 may be formed in the mounting portion 1122. The depth dimension of the second groove 1124 may be equal to the thickness dimension of the heat sink 150 so that the heat sink 150 can be completely received in the second groove 1124.

The thickness of the energy storage unit 133 is a first size, and the thickness of the heat sink 150 is a second size, so that the protective case 100 is light and thin and is easy to hold, and the thickness of the mounting portion 1122 is as close as possible to the larger one of the first size and the second size. For example, the thickness dimension of the mounting portion 1122 may be 1.1 to 1.3 times the larger of the first and second dimensions.
