[0006] In view of this, the present application provides a heating device, comprising: a shell, the shell having a side plate, the side plate having a first plate body and a second plate body arranged oppositely; a heating structure, arranged in the shell, the heating structure comprising: a mounting plate, the mounting plate connected between the first plate body and the second plate body, the mounting plate having a first end face and a second end face arranged oppositely; a plurality of heating elements, the plurality of heating elements are all arranged on the first end face, and the plurality of heating elements are arranged at intervals along the direction from the first plate body to the second plate body; along the first plate body to the second plate body, the distance from the second end face to the first end face first increases and then decreases or first decreases and then increases; and / or a support member, the support member is connected between the second end face and the inner surface of the shell.

[0007] The heating device provided in the present application includes a shell and a heating structure, or the heating device includes a shell, a heating structure and a support.

[0008] Specifically, the heating device includes a shell and a heating structure. The shell has a side plate, the side plate has a first plate body and a second plate body, the first plate body and the second plate body are arranged oppositely and spaced apart. The heating structure includes a mounting plate and a plurality of heating elements, the mounting plate has a first end face and a second end face, the first end face and the second end face are arranged oppositely and spaced apart. The plurality of heating elements are all arranged on the first end face. Along the first plate body to the second plate body, the distance from the second end face to the first end face first increases and then decreases. Alternatively, along the first plate body to the second plate body, the distance from the second end face to the first end face first decreases and then increases.

[0009] Specifically, the heating device includes a shell, a heating structure and a support member. The shell has a side plate, the side plate has a first plate body and a second plate body, the first plate body and the second plate body are arranged oppositely and spaced apart. The heating structure includes a mounting plate and a plurality of heating elements, the mounting plate has a first end face and a second end face, the first end face and the second end face are arranged oppositely and spaced apart. The plurality of heating elements are all arranged on the first end face. Along the first plate body to the second plate body, the distance from the second end face to the first end face first increases and then decreases. Alternatively, along the first plate body to the second plate body, the distance from the second end face to the first end face first decreases and then increases. The support member is connected between the second end face of the mounting plate and the inner surface of the shell.

[0010] Specifically, the heating device includes a shell, a heating structure and a support member. The shell has a side plate, the side plate has a first plate body and a second plate body, the first plate body and the second plate body are arranged oppositely and spaced apart. The heating structure includes a mounting plate and a plurality of heating elements, the mounting plate has a first end face and a second end face, the first end face and the second end face are arranged oppositely and spaced apart. The plurality of heating elements are all arranged on the first end face. The support member is connected between the second end face of the mounting plate and the inner surface of the shell.

[0011] The mounting plate serves as a mounting carrier for multiple heating elements and has the function of mounting and fixing the multiple heating elements.

[0012] It can be understood that, along the first plate body to the second plate body, the distance from the second end face to the first end face first increases and then decreases, or first decreases and then increases. For example, along the first plate body to the second plate body, the mounting plate includes a first mounting section, a second mounting section and a third mounting section, and the second mounting section is connected between the first mounting section and the third mounting section. The thickness of either the first mounting section or the third mounting section is greater than the thickness of the second mounting section, or the thickness of either the first mounting section or the third mounting section is less than the thickness of the second mounting section. In other words, the mounting plate is a plate that is thick in the middle and thin at both ends, or the mounting plate is a plate that is thin in the middle and thick at both ends.

[0013] When the mounting plate is a plate that is thin in the middle and thick at both ends, the support and stability of the mounting plate are enhanced, and the force on the mounting plate can be concentrated on the connection between the mounting plate and the shell. In this way, the middle part of the mounting plate can be prevented from collapsing, the probability of deformation of the mounting plate can be reduced, and the service life of the mounting plate can be improved.

[0014] When the mounting plate is thick in the middle and thin at both ends, the load applied by multiple heating elements to the mounting plate (especially the middle part of the mounting plate) can be effectively dispersed, the collapse of the middle part of the mounting plate can be avoided, the probability of deformation of the mounting plate can be reduced, and the service life of the mounting plate can be improved.

[0015] It is understandable that when the heating device includes a support member, one end of the support member is connected to the second end surface of the mounting plate, and the other end of the support member is connected to the inner surface of the shell. The support member has the function of supporting and fixing the mounting plate, and the support member cooperates with the mounting plate to improve the overall bearing capacity, so that the mounting plate can be prevented from collapsing, the probability of deformation of the mounting plate can be reduced, and the service life of the mounting plate can be improved.

[0016] It can be seen from this that the present application reasonably arranges the structure of the heating device, improves the supporting strength of the mounting plate, avoids partial collapse of the mounting plate due to long-term use, can ensure the heating efficiency of the heating device, is conducive to extending the service life of the heating device, and provides structural support to ensure the safety and reliability of the use of the heating device.

[0017] Among them, the mounting plate is connected between the first plate body and the second plate body, and the plurality of heating elements are arranged at intervals along the direction from the first plate body to the second plate body. That is, the matching structure of the mounting plate, the plurality of heating elements and the shell is defined. The side plate of the shell has the function of installing and fixing the mounting plate, which can ensure the matching size of the plurality of heating elements and the panel of the shell. In addition, this setting increases the matching area and matching size between the heating structure and the panel of the shell, which can increase the heating area of ​​the heating device, so that the device can be effectively heated in each area of ​​the panel, realizing full-area heating of the heating device.

[0018] The heating device described above in this application may also have the following additional technical features:

[0019] In some embodiments, optionally, when the distance from the second end surface to the first end surface first increases and then decreases or first decreases and then increases, the first end surface is a plane and at least a portion of the second end surface is an arcuate surface.

[0020] In this embodiment, the structure of the mounting plate is further defined.

[0021] The mounting plate has a first end surface and a second end surface, the first end surface and the second end surface are arranged opposite to each other and spaced apart. When the distance from the second end surface to the first end surface increases first and then decreases, or the distance from the second end surface to the first end surface decreases first and then increases, the first end surface is a plane, the second end surface is an arcuate surface, or a part of the second end surface is an arcuate surface.

[0022] When at least a portion of the second end surface is an arcuate surface, and the distance from the second end surface to the first end surface increases first and then decreases, the mounting plate is an inversely arched plate, that is, the two ends of the mounting plate are thin, and the middle of the mounting plate is thick. This arrangement can effectively disperse the load applied by multiple heating elements to the mounting plate (especially the middle part of the mounting plate), can avoid the middle part of the mounting plate from collapsing, can reduce the probability of deformation of the mounting plate, and is conducive to extending the service life of the mounting plate.

[0023] When at least a portion of the second end surface is an arcuate surface, and the distance from the second end surface to the first end surface first decreases and then increases, the mounting plate is an arched plate, that is, the two ends of the mounting plate are thick, and the middle of the mounting plate is thin. This setting can enhance the support and stability of the mounting plate, and can make the force of the mounting plate concentrated on the connection between the mounting plate and the shell, so that the middle part of the mounting plate can be prevented from collapsing, the probability of deformation of the mounting plate can be reduced, and it is beneficial to extend the service life of the mounting plate.

[0024] Optionally, when a portion of the second end surface is an arcuate surface, another portion of the second end surface is a plane. For example, the second end surface includes two planes and an arcuate surface, and the arcuate surface is connected between the two planes.

[0025] In some embodiments, optionally, in the cross-section of the mounting plate, the angle between the end extension line of the contour line of the arc surface and the contour line of the first end surface is greater than 0° and less than or equal to 10°; wherein the first plate body and the second plate body are both perpendicular to the cross-section of the mounting plate.

[0026] In this embodiment, the structure of the mounting plate is further defined.

[0027] Specifically, in the cross section of the mounting plate, the angle between the end extension line of the contour line of the arc surface and the contour line of the first end surface is recorded as a, where 0°<a≤10°. This arrangement can satisfy the requirement that the distance from the first plate body to the second plate body and from the second end surface to the first end surface first increases and then decreases or first decreases and then increases, and can also avoid excessive thickness of a local area of ​​the mounting plate, can reduce the material input of the mounting plate, and take into account both the cost and service life of the mounting plate.

[0028] Optionally, the angle between the end extension line of the contour line of the arcuate surface and the contour line of the first end surface includes 1°, 2°, 3°, 4°, 5°, 6°, 7°, 8° and 9°, etc., which are not listed here one by one.

[0029] In some embodiments, optionally, the maximum value of the distance from the second end surface to the first end surface is greater than or equal to 2 mm.

[0030] In this embodiment, the structure of the mounting plate is further defined.

[0031] Specifically, the maximum value of the distance from the second end surface to the first end surface is greater than or equal to 2 mm. This arrangement can ensure the supporting strength of the mounting plate and prevent the mounting plate from partially collapsing due to long-term use.

[0032] If the maximum value of the distance from the second end face to the first end face is less than 2 mm, the thickness of the mounting plate is small, and the mounting plate is prone to collapse, which will reduce the service life of the mounting plate.

[0033] In some embodiments, optionally, when the heating device includes a support member, the support member is connected to the middle portion of the second end surface along the first plate body to the second plate body.

[0034] In this embodiment, when the heating device includes a support member, a matching structure of the mounting plate and the support member is further defined.

[0035] Specifically, along the first plate body to the second plate body, the support member is connected between the middle portion of the second end surface and the inner surface of the shell.

[0036] As the heating structure is used for a longer time, the probability of the middle area of ​​the mounting plate collapsing also increases. Therefore, the support is connected to the middle of the second end surface of the mounting plate to use the support to strengthen the structural strength of the middle of the mounting plate. In this way, the probability of the middle of the mounting plate collapsing can be reduced. While reducing the material input of the support, the probability of the mounting plate deformation is reduced, which is conducive to extending the service life of the mounting plate. In other words, this setting takes into account the production cost of the heating device and the service life of the mounting plate, and improves the performance, stability and reliability of the heating device.

[0037] In some embodiments, optionally, when the heating device includes a plurality of support members, the plurality of support members are arranged at intervals along a direction from the first plate body to the second plate body.

[0038] In this embodiment, when the heating device includes a support member, a matching structure of the mounting plate and the support member is further defined.

[0039] Specifically, a plurality of support members are arranged at intervals along the direction from the first plate body to the second plate body. This arrangement increases the matching area and matching angle of the mounting plate, the support member and the housing, so as to support and fix the mounting plate from multiple directions and multiple angles, and can enhance the structural strength and rigidity at different positions of the mounting plate, so as to effectively avoid the partial collapse of the mounting plate due to long-term use, and can ensure the heating efficiency of the heating device, which is conducive to extending the service life of the heating device, and provides structural support for ensuring the safety and reliability of the use of the heating device.

[0040] In some embodiments, optionally, at least one of the first plate body and the second plate body is provided with a slot, and the mounting plate is clamped in the slot.

[0041] In this embodiment, the matching structure of the housing and the mounting plate is further defined.

[0042] Specifically, at least one of the first plate body and the second plate body is provided with a slot, and the mounting plate is mounted in the slot. The first plate body is provided with a slot, and the mounting plate is mounted in the slot. Alternatively, the second plate body is provided with a slot, and the mounting plate is mounted in the slot. Alternatively, both the first plate body and the second plate body are provided with a slot, and one end of the mounting plate is mounted in the slot of the first plate body, and the other end of the mounting plate is mounted in the slot of the second plate body.

[0043] This arrangement can not only ensure the effectiveness and feasibility of stable assembly of the mounting plate and the shell, but also effectively limit the mounting plate (for example, limit the mounting plate in a direction perpendicular to the first plate body to the second plate body) to ensure the matching dimensions of the mounting plate and the shell, and further ensure the matching dimensions of multiple heating elements and other components of the heating device (for example, the mainboard of the heating device, for example, the electronic components of the heating device).

[0044] In some embodiments, optionally, at least one of the first plate body and the second plate body is provided with a support plate and a plurality of retaining rings, the plurality of retaining rings are spaced apart on the support plate, and any two adjacent retaining rings and the support plate enclose a card slot.

[0045] In this embodiment, the matching structure of the housing and the mounting plate is further defined.

[0046] Specifically, the first plate body is provided with a support plate and a plurality of retaining rings, and the second plate body is provided with a support plate and a plurality of retaining rings, or either the first plate body or the second plate body is provided with a support plate and a plurality of retaining rings.

[0047] A plurality of retaining rings are arranged at intervals on the support plate, and any two adjacent retaining rings and the support plate enclose a card slot.

[0048] When the mounting plate and the housing are assembled, the end of the mounting plate rests on the supporting plate, and the mounting plate abuts between two adjacent retaining rings. That is, the mounting plate is clamped in the clamping groove.

[0049] This setting can ensure the matching size and matching area of ​​the mounting plate and the shell, can limit the mounting plate from multiple directions, can ensure the matching size of the mounting plate and the shell, and further can ensure the matching size of multiple heating elements and other components of the heating device (such as the mainboard of the heating device, such as the electronic components of the heating device).

[0050] In some embodiments, optionally, the heating structure further includes a plurality of elastic members, each of which is connected between a mounting plate and a heating member; the shell further includes a back plate, a side plate is connected to the peripheral side of the back plate, and the mounting plate is located between the heating member and the back plate.

[0051] In this embodiment, the matching structure of the heating structure and the housing is further defined.

[0052] The heating structure also includes a plurality of elastic members, each of which is used in conjunction with a heating member. Specifically, each elastic member is connected between a mounting plate and a heating member. The elastic member has the function of supporting the heating member to push the heating member toward the panel of the shell to ensure the matching dimensions of the heating member and the panel of the shell, so that the heating member can effectively heat the device located on the panel to ensure the heating efficiency of the heating device.

[0053] It can be understood that the front panel of the housing and the back panel of the housing are arranged oppositely and spaced apart, and the side panel is connected between the front panel and the back panel. The side panel extends along the circumference of the front panel, and the side panel extends along the circumference of the back panel.

[0054] The structural arrangement of the elastic part helps to reduce the assembly accuracy requirements of the heating element and the mounting plate while ensuring the matching dimensions of the heating element and the panel of the shell, helps to reduce the processing accuracy of the heating structure, and helps to reduce the production cost of the product.

[0055] In some embodiments, optionally, the mounting plate is provided with a plurality of mounting holes, each heating element is arranged opposite to a mounting hole, and the elastic element abuts against the portion of the first end surface located on the peripheral side of the mounting hole; the heating element is provided with a first clamping portion and a second clamping portion, the first clamping portion is clamped with the elastic element, and the second clamping portion passes through the mounting hole and is clamped with the second end surface.

[0056] In this embodiment, the matching structure of the heating element, the mounting plate and the elastic element is further defined.

[0057] The mounting plate is provided with a plurality of mounting holes, and each heating element is arranged opposite to a mounting hole. For example, the number of mounting holes is the same as the number of heating elements, and the mounting holes and the heating elements correspond one to one. For example, the number of mounting holes is greater than the number of heating elements, and each heating element is matched with a mounting hole.

[0058] Specifically, the heating element is provided with a first clamping portion, and the first clamping portion is clamped with the elastic element, so that the heating element and the elastic element are detachably connected together.

[0059] Specifically, the heating element is provided with a second clamping portion, which passes through the mounting hole and is clamped with the second end surface, so that the heating element and the mounting plate are detachably connected together.

[0060] It can be understood that the elastic member is in contact with the portion of the first end surface located on the peripheral side of the mounting hole, and the elastic member is clamped with the first clamping portion of the heating member, that is, the elastic member is connected between the mounting plate and the heating member. The second clamping portion is clamped with the mounting plate to limit the maximum matching clearance between the heating member and the mounting plate, and the elastic member can push the heating member upward to ensure the matching size of the heating member and the panel of the housing.

[0061] Optionally, the heating element and the elastic element are detachably connected. This arrangement ensures the reliability of the connection between the heating element and the elastic element while facilitating the cleaning and maintenance of the heating element and the elastic element. That is, the heating element and the elastic element can be separated or assembled together according to actual use needs. This arrangement simplifies the assembly structure of the heating element and the elastic element, simplifies the disassembly and assembly process, reduces the difficulty of disassembly and assembly of the heating element and the elastic element, and facilitates the cleaning of the heating element and the elastic element and subsequent repair and maintenance.

The heating structure 200 includes a mounting plate 210 and a plurality of heating elements 220, and the mounting plate 210 has a first end surface 212 and a second end surface 214, and the first end surface 212 and the second end surface 214 are arranged oppositely and spaced apart. The plurality of heating elements 220 are all arranged on the first end surface 212. The support member 300 is connected between the second end surface 214 of the mounting plate 210 and the inner surface of the housing 100.

[0106] The mounting plate 210 serves as a mounting carrier for the plurality of heating elements 220 and has the function of mounting and fixing the plurality of heating elements 220 .

[0107] It can be understood that, along the first plate body 112 to the second plate body 114, the distance from the second end face 214 to the first end face 212 first increases and then decreases, or first decreases and then increases. For example, along the first plate body 112 to the second plate body 114, the mounting plate 210 includes a first mounting section, a second mounting section, and a third mounting section, and the second mounting section is connected between the first mounting section and the third mounting section. The thickness of either the first mounting section or the third mounting section is greater than the thickness of the second mounting section, or the thickness of either the first mounting section or the third mounting section is less than the thickness of the second mounting section. In other words, the mounting plate 210 is a plate that is thick in the middle and thin at both ends, or the mounting plate 210 is a plate that is thin in the middle and thick at both ends.

[0108] When the mounting plate 210 is a plate that is thin in the middle and thick at both ends, the support and stability of the mounting plate 210 are enhanced, and the force on the mounting plate 210 can be concentrated on the connection between the mounting plate 210 and the shell 100. In this way, the middle part of the mounting plate 210 can be avoided from collapsing, and the probability of deformation of the mounting plate 210 can be reduced, which is beneficial to improving the service life of the mounting plate 210.

[0109] When the mounting plate 210 is a plate that is thick in the middle and thin at both ends, the load applied by multiple heating elements 220 to the mounting plate 210 (especially the middle part of the mounting plate 210) can be effectively dispersed, the middle part of the mounting plate 210 can be prevented from collapsing, the probability of deformation of the mounting plate 210 can be reduced, and the service life of the mounting plate 210 is improved.

[0110] It is understandable that when the heating device 10 includes the support member 300, one end of the support member 300 is connected to the second end surface 214 of the mounting plate 210, and the other end of the support member 300 is connected to the inner surface of the housing 100. The support member 300 has the function of supporting and fixing the mounting plate 210, and the support member 300 cooperates with the mounting plate 210 to improve the overall bearing capacity, so that the mounting plate 210 can be prevented from collapsing, the probability of deformation of the mounting plate 210 can be reduced, and the service life of the mounting plate 210 can be improved.

[0111] It can be seen from this that the present application reasonably arranges the structure of the heating device 10, improves the supporting strength of the mounting plate 210, avoids the partial collapse of the mounting plate 210 due to long-term use, can ensure the heating efficiency of the heating device 10, is beneficial to extend the service life of the heating device 10, and provides structural support to ensure the safety and reliability of the use of the heating device 10.

[0112] Among them, the mounting plate 210 is connected between the first plate body 112 and the second plate body 114, and the plurality of heating elements 220 are arranged at intervals along the direction from the first plate body 112 to the second plate body 114. That is, the matching structure of the mounting plate 210, the plurality of heating elements 220 and the shell 100 is defined. The side plate 110 of the shell 100 has the function of installing and fixing the mounting plate 210, and can ensure the matching size of the plurality of heating elements 220 and the panel of the shell 100. In addition, this setting increases the matching area and matching size of the heating structure 200 and the panel of the shell 100, which can increase the heating area of ​​the heating device 10, so that the device can be effectively heated in each area of ​​the panel, and the heating device 10 is heated in the whole area.

[0113] Optionally, the heating element 220 includes any one of the following or a combination thereof: a coil disk, a resistance wire, and a heating tube, which are not listed here one by one.

[0114] In some embodiments, optionally, when the distance from the second end surface 214 to the first end surface 212 first increases and then decreases or first decreases and then increases, the first end surface 212 is a plane and at least a portion of the second end surface 214 is an arcuate surface.

[0115] In this embodiment, the structure of the mounting plate 210 is further defined.

[0116] The mounting plate 210 has a first end surface 212 and a second end surface 214, and the first end surface 212 and the second end surface 214 are arranged opposite to each other and spaced apart. When the distance from the second end surface 214 to the first end surface 212 increases first and then decreases, or the distance from the second end surface 214 to the first end surface 212 decreases first and then increases, the first end surface 212 is a plane, the second end surface 214 is an arcuate surface, or a portion of the second end surface 214 is an arcuate surface.

[0117] like Fig. 9 As shown, when at least a portion of the second end surface 214 is an arcuate surface, and the distance from the second end surface 214 to the first end surface 212 increases first and then decreases, the mounting plate 210 is an inversely arched plate, that is, the two ends of the mounting plate 210 are thin, and the middle of the mounting plate 210 is thick. This arrangement can effectively disperse the load applied by the multiple heating elements 220 to the mounting plate 210 (especially the middle part of the mounting plate 210), can avoid the middle part of the mounting plate 210 from collapsing, can reduce the probability of deformation of the mounting plate 210, and is conducive to extending the service life of the mounting plate 210.

[0118] like Fig.10 As shown, when at least a portion of the second end surface 214 is an arcuate surface, and the distance from the second end surface 214 to the first end surface 212 is first reduced and then increased, the mounting plate 210 is an arched plate, that is, the two ends of the mounting plate 210 are thick, and the middle of the mounting plate 210 is thin. This setting can enhance the support and stability of the mounting plate 210, and can make the force of the mounting plate 210 concentrated on the connection between the mounting plate 210 and the housing 100, so that the middle part of the mounting plate 210 can be prevented from collapsing, and the probability of deformation of the mounting plate 210 can be reduced, which is conducive to extending the service life of the mounting plate 210.

[0119] Optionally, when a portion of the second end surface 214 is an arcuate surface, another portion of the second end surface 214 is a plane. For example, the second end surface 214 includes two planes and an arcuate surface, and the arcuate surface is connected between the two planes.

[0120] In some embodiments, optionally, Fig. 9 and Fig.10 As shown, in the cross section 218 of the mounting plate, the included angle between the end extension line 2142 of the contour line of the arcuate surface and the contour line 2122 of the first end surface is greater than 0° and less than or equal to 10°.

[0121] The first plate body 112 and the second plate body 114 are both perpendicular to the cross section 218 of the mounting plate.

[0122] In this embodiment, the structure of the mounting plate 210 is further defined.

[0123] Specifically, in the cross section 218 of the mounting plate, the angle between the end extension line 2142 of the contour line of the arc surface and the contour line 2122 of the first end surface is recorded as a, where 0°<a≤10°. This arrangement can satisfy the requirement that the distance from the first plate body 112 to the second plate body 114 and from the second end surface 214 to the first end surface 212 first increases and then decreases or first decreases and then increases, and can also avoid the thickness of the local area of ​​the mounting plate 210 being too large, can reduce the material input of the mounting plate 210, and take into account the cost and service life of the mounting plate 210.

[0124] Optionally, the angle a between the end extension line 2142 of the contour line of the arc surface and the contour line 2122 of the first end surface includes 1°, 2°, 3°, 4°, 5°, 6°, 7°, 8° and 9°, etc., which are not listed here one by one.

[0125] It is understandable that the first plate 112 and the second plate 114 are perpendicular to the cross section 218 of the mounting plate, that is, the first plate 112 is perpendicular to the cross section 218 of the mounting plate, and the second plate 114 is perpendicular to the cross section 218 of the mounting plate. The mounting plate 210 is a strip plate, and the cross section 218 of the mounting plate extends along the length direction of the strip plate.

[0126] In some embodiments, optionally, Fig. 9 and Fig.10 As shown, the maximum value of the distance from the second end surface 214 to the first end surface 212 is greater than or equal to 2 mm.

[0127] In this embodiment, the structure of the mounting plate 210 is further defined.

[0128] Specifically, the maximum value of the distance d from the second end surface 214 to the first end surface 212 is greater than or equal to 2 mm. This arrangement can ensure the support strength of the mounting plate 210 and prevent the mounting plate 210 from partially collapsing due to long-term use.

[0129] If the maximum value d of the distance from the second end surface 214 to the first end surface 212 is less than 2 mm, the thickness of the mounting plate 210 is relatively small, and the mounting plate 210 is prone to collapse, which will reduce the service life of the mounting plate 210 .

[0130] Optionally, a value of the distance d from the second end surface 214 to the first end surface 212 includes 2.5 mm, 3 mm, 3.5 mm, 4 mm, 4.5 mm, 5 mm, etc., which are not listed here one by one.

[0131] In some embodiments, optionally, Figure 2 and Figure 3 As shown, when the heating device 10 includes the support member 300 , the support member 300 is connected to the middle portion 2144 of the second end surface along the first plate body 112 to the second plate body 114 .

[0132] In this embodiment, when the heating device 10 includes the support member 300 , the matching structure of the mounting plate 210 and the support member 300 is further defined.

[0133] Specifically, along the first plate body 112 to the second plate body 114 , the support member 300 is connected between the middle portion 2144 of the second end surface and the inner surface of the housing 100 .

[0134] As the use time of the heating structure 200 increases, the probability of the middle area of ​​the mounting plate 210 collapsing also increases. Therefore, the support member 300 is connected to the middle part 2144 of the second end surface of the mounting plate 210, so as to use the support member 300 to strengthen the structural strength of the middle part of the mounting plate 210. In this way, the probability of the middle part of the mounting plate 210 collapsing can be reduced. When the material input of the support member 300 is reduced, the probability of the mounting plate 210 being deformed is reduced, which is conducive to extending the service life of the mounting plate 210. In other words, this setting takes into account the production cost of the heating device 10 and the service life of the mounting plate 210, and improves the performance, stability and reliability of the heating device 10.

[0135] In some embodiments, optionally, when the heating device 10 includes a plurality of support members 300 , the plurality of support members 300 are arranged at intervals along a direction from the first plate body 112 to the second plate body 114 .

[0136] In this embodiment, when the heating device 10 includes the support member 300 , the matching structure of the mounting plate 210 and the support member 300 is further defined.

[0137] Specifically, a plurality of support members 300 are arranged at intervals along the direction from the first plate body 112 to the second plate body 114. This arrangement increases the matching area and matching angle of the mounting plate 210, the support member 300 and the housing 100, so as to support and fix the mounting plate 210 from multiple directions and multiple angles, and can enhance the structural strength and rigidity at different positions of the mounting plate 210, so as to effectively avoid the partial collapse of the mounting plate 210 due to long-term use, and can ensure the heating efficiency of the heating device 10, which is conducive to extending the service life of the heating device 10, and provides structural support for ensuring the safety and reliability of the use of the heating device 10.

[0138] In some embodiments, optionally, Figure 2 and Figure 4As shown, at least one of the first plate 112 and the second plate 114 is provided with a slot 120 .

[0139] The mounting plate 210 is locked in the slot 120 .

[0140] In this embodiment, the matching structure of the housing 100 and the mounting plate 210 is further defined.

[0141] Specifically, at least one of the first plate body 112 and the second plate body 114 is provided with a slot 120, and the mounting plate 210 is clamped in the slot 120. The first plate body 112 is provided with a slot 120, and the mounting plate 210 is clamped in the slot 120. Alternatively, the second plate body 114 is provided with a slot 120, and the mounting plate 210 is clamped in the slot 120. Alternatively, both the first plate body 112 and the second plate body 114 are provided with a slot 120, one end of the mounting plate 210 is clamped in the slot 120 of the first plate body 112, and the other end of the mounting plate 210 is clamped in the slot 120 of the second plate body 114.

[0142] This arrangement can not only ensure the effectiveness and feasibility of the stable assembly of the mounting plate 210 and the shell 100, but also effectively limit the mounting plate 210 (for example, limiting the mounting plate 210 in a direction perpendicular to the first plate body 112 to the second plate body 114) to ensure the matching dimensions of the mounting plate 210 and the shell 100, and further ensure the matching dimensions of the multiple heating elements 220 and other components of the heating device 10 (for example, the mainboard of the heating device 10, for example, the electronic components of the heating device 10).

[0143] In some embodiments, optionally, Figure 2 and Figure 4 As shown, at least one of the first plate body 112 and the second plate body 114 is provided with a support plate 130 and a plurality of retaining rings 140 .

[0144] A plurality of retaining rings 140 are disposed on the support plate 130 at intervals.

[0145] Any two adjacent retaining rings 140 and the supporting plates 130 enclose a slot 120 .

[0146] In this embodiment, the matching structure of the housing 100 and the mounting plate 210 is further defined.

[0147] Specifically, the first plate 112 is provided with a support plate 130 and a plurality of retaining rings 140 , and the second plate 114 is provided with a support plate 130 and a plurality of retaining rings 140 . Alternatively, either the first plate 112 or the second plate 114 is provided with a support plate 130 and a plurality of retaining rings 140 .

[0148] A plurality of retaining rings 140 are disposed at intervals on the support plate 130 , and any two adjacent retaining rings 140 and the support plate 130 enclose a card slot 120 .

[0149] When the mounting plate 210 and the housing 100 are assembled, the end of the mounting plate 210 rests on the support plate 130 , and the mounting plate 210 abuts between two adjacent retaining rings 140 . That is, the mounting plate 210 is clamped in the clamping groove 120 .

[0150] This arrangement can ensure the matching dimensions and matching areas of the mounting plate 210 and the shell 100, can limit the mounting plate 210 from multiple directions, can ensure the matching dimensions of the mounting plate 210 and the shell 100, and further can ensure the matching dimensions of multiple heating elements 220 and other components of the heating device 10 (such as the mainboard of the heating device 10, such as the electronic components of the heating device 10).

[0151] Optionally, the retaining ring 140 is an elastic ring, and the mounting plate 210 and the slot 120 are interference fit.

[0152] In some embodiments, optionally, Figure 5 and Figure 6 As shown, the heating structure 200 further includes a plurality of elastic members 230 .

[0153] Each elastic member 230 is connected between the mounting plate 210 and one heating member 220 .

[0154] like Figure 5 As shown, the housing 100 further has a back plate 150 .

[0155] The side plate 110 is connected to the peripheral side of the back plate 150 .

[0156] The mounting plate 210 is located between the heating element 220 and the back plate 150 .

[0157] In this embodiment, the matching structure of the heating structure 200 and the housing 100 is further defined.

[0158] The heating structure 200 also includes a plurality of elastic members 230, each of which is used in conjunction with a heating member 220. Specifically, each elastic member 230 is connected between the mounting plate 210 and a heating member 220. The elastic member 230 has a function of supporting the heating member 220 to lift the heating member 220 toward the panel of the shell 100 to ensure the matching dimensions of the heating member 220 and the panel of the shell 100, so that the heating member 220 can effectively heat the device located on the panel to ensure the heating efficiency of the heating device 10.

[0159] It can be understood that the front panel of the housing 100 and the back panel 150 of the housing 100 are arranged oppositely and spaced apart, and the side panel 110 is connected between the front panel and the back panel 150. The side panel 110 extends along the circumference of the front panel, and the side panel 110 extends along the circumference of the back panel 150.

[0160] The structural setting of the elastic member 230 helps to reduce the assembly accuracy requirements of the heating member 220 and the mounting plate 210 while ensuring the matching dimensions of the panel of the heating member 220 and the shell 100, helps to reduce the processing accuracy of the heating structure 200, and helps to reduce the production cost of the product.

[0161] Optionally, the housing 100 further comprises a panel, the side plate 110 is connected to the peripheral side of the panel, and the heating element 220 is located between the mounting plate 210 and the panel, so as to ensure the matching size of the heating element 220 and the appliance placed on the panel.

[0162] Optionally, the elastic member 230 includes any one of the following or a combination thereof: a spring, a clip spring, and a tension spring.

[0163] In some embodiments, optionally, Figure 2 , Figure 4 , Figure 5 , Figure 7 , Figure 8 and Fig.11 As shown, the mounting plate 210 is provided with a plurality of mounting holes 216 , and each heating element 220 is disposed opposite to a mounting hole 216 .

[0164] The elastic member 230 abuts against a portion of the first end surface 212 located around the mounting hole 216 .

[0166] The first engaging portion 222 is engaged with the elastic member 230 .

[0167] The second engaging portion 224 passes through the mounting hole 216 and is engaged with the second end surface 214 .

[0168] In this embodiment, the matching structure of the heating element 220, the mounting plate 210 and the elastic element 230 is further defined.

[0169] The mounting plate 210 is provided with a plurality of mounting holes 216, and each heating element 220 is disposed opposite to one mounting hole 216. For example, the number of mounting holes 216 is the same as the number of heating elements 220, and the mounting holes 216 and the heating elements 220 correspond one to one. For example, the number of mounting holes 216 is greater than the number of heating elements 220, and each heating element 220 is matched with one mounting hole 216.

[0170] Specifically, the heating element 220 is provided with a first clamping portion 222 , and the first clamping portion 222 is clamped with the elastic element 230 , so that the heating element 220 and the elastic element 230 are detachably connected together.

[0172] It can be understood that the elastic member 230 is in contact with the portion of the first end surface 212 located on the periphery of the mounting hole 216, and the elastic member 230 is engaged with the first engaging portion 222 of the heating member 220, that is, the elastic member 230 is connected between the mounting plate 210 and the heating member 220. The second engaging portion 224 is engaged with the mounting plate 210 to limit the maximum matching clearance between the heating member 220 and the mounting plate 210, and the elastic member 230 can push the heating member 220 upward to ensure the matching size between the heating member 220 and the panel of the housing 100.

[0173] Optionally, the heating element 220 and the elastic element 230 can be detachably connected. This arrangement ensures the reliability of the connection between the heating element 220 and the elastic element 230 while facilitating the cleaning and maintenance of the heating element 220 and the elastic element 230. That is, the heating element 220 and the elastic element 230 can be separated or assembled together according to actual use needs. This arrangement simplifies the assembly structure of the heating element 220 and the elastic element 230, simplifies the disassembly and assembly process, reduces the difficulty of disassembly and assembly of the heating element 220 and the elastic element 230, and facilitates the cleaning of the heating element 220 and the elastic element 230 and the subsequent repair and maintenance.

[0176] Optionally, there are multiple first clamping parts 222, and the multiple first clamping parts 222 are arranged at intervals along the circumference of the second clamping part 224. This arrangement increases the matching area and matching angle of the heating element 220 and the elastic member 230, so that the heating element 220 can be limited from multiple directions to ensure that different positions of the heating element 220 can be effectively connected with the elastic member 230, to ensure that the elastic member 230 acts on different positions of the heating element 220, to avoid the heating element 220 from tilting when the elastic member 230 lifts the heating element 220, and to ensure the matching size of the heating element 220 and the panel.

[0177] Optionally, the second clamping portion 224 includes a surrounding plate and a plurality of clamping plates, and the plurality of clamping plates are arranged at intervals along the circumference of the surrounding plate. This arrangement increases the matching area and matching angle between the heating element 220 and the mounting plate 210, so that the heating element 220 can be limited from multiple directions to ensure that different positions of the heating element 220 can be effectively connected to the mounting plate 210, to ensure the matching clearance between different positions of the heating element 220 and the mounting plate 210, to avoid the heating element 220 from tilting when the elastic member 230 lifts the heating element 220, and to ensure the matching size of the heating element 220 and the panel.

[0179] The plurality of heating structures 200 are arranged at intervals and in a flat pattern.

[0180] In this embodiment, the number and arrangement positions of the heating structures 200 are further defined.

[0181] There are multiple heating structures 200, and the multiple heating structures 200 are arranged at intervals and in a flat pattern. That is, the multiple heating structures 200 are arranged at intervals in a direction perpendicular to the first plate 112 and the second plate 114, and the multiple heating structures 200 are arranged in a flat pattern. This arrangement increases the matching area and matching size between the heating structure 200 and the panel of the housing 100, and can increase the heating area of ​​the heating device 10, so that the device can be effectively heated in each area of ​​the panel, and the heating device 10 can be heated in the entire area.

[0182] It can be understood that the appliance is placed on the panel of the housing 100, and the heating structure 200 is used to heat the appliance.

[0184] The other of the mounting plate 210 and the side plate 110 is provided with a protrusion 500.

[0185] The protrusion 500 is located in the slide groove 600 .

[0186] In this embodiment, the matching structure of the housing 100 and the mounting plate 210 is further defined.

[0187] Specifically, one of the mounting plate 210 and the side plate 110 is provided with a slide groove 600, and the other is provided with a convex portion 500.

Alternatively, the mounting plate 210 is provided with a convex portion 500, and the side plate 110 is provided with a slide groove 600. The convex portion 500 can slide into the slide groove 600.

[0188] When the mounting plate 210 and the housing 100 are assembled, the protrusion 500 slides into the slide groove 600 .

[0189] This arrangement can ensure the matching dimensions and matching areas of the mounting plate 210 and the shell 100, can limit the mounting plate 210 from multiple directions, can ensure the matching dimensions of the mounting plate 210 and the shell 100, and further can ensure the matching dimensions of multiple heating elements 220 and other components of the heating device 10 (such as the mainboard of the heating device 10, such as the electronic components of the heating device 10).

The 9 aluminum bar brackets are fixed to the side panels 110 of the housing 100 by means of snaps, gluing, etc. Below the aluminum bar brackets are the main board and various electronic components. Above the aluminum bar brackets are a plurality of heating elements 220, which are fixed to the aluminum bar brackets by elastic elements 230 (such as springs), and the springs lift the heating elements 220 and stop them below the microcrystalline panel of the housing 100.

[0193] The mounting plate 210 is an inverted arch structure, and includes a first end face 212 and a second end face 214, which are arranged opposite to each other and spaced apart. The first end face 212 is a plane, and the second end face 214 is an inverted arch surface. That is, the thickness of the middle portion of the mounting plate 210 is greater than the thickness of the two end portions. This arrangement can effectively disperse the load applied to the mounting plate 210 by the plurality of heating elements 220.

[0194] The mounting plate 210 may also be an arched structure, and the mounting plate 210 includes a first end face 212 and a second end face 214, which are arranged opposite to each other and spaced apart. The first end face 212 is a plane, and the second end face 214 is an arched surface. The mounting plate 210 is similar to a bridge hole, and the thickness of the two end portions of the mounting plate 210 is greater than the thickness of the middle portion. This arrangement can effectively prevent the middle portion of the mounting plate 210 from collapsing.

[0195] When the mounting plate 210 is an inverted arch structure or an arch structure, the angle a between the two end extension lines of the arch surface or the inverted arch surface and the first end surface 212 is greater than 0° and less than or equal to 10°. If the angle a is greater than or equal to 10°, the thickness of the thicker portion of the mounting plate 210 is too large.

[0196] The maximum value of the thickness of the mounting plate 210 is greater than or equal to 2 mm. If the maximum value of the thickness of the mounting plate 210 is less than 2 mm, the mounting plate 210 is prone to collapse.

[0197] This arrangement can improve the supporting strength of the mounting plate 210, prevent the mounting plate 210 from collapsing in the middle due to being too long, and improve the reliability of the entire system.

[0198] Optionally, an additional support member 300 is added to the middle portion of the mounting plate 210 , and the mounting plate 210 is lifted up by the support member 300 .

[0199] A support member 300 is provided on the back plate 150 of the main board or the shell 100 to lift up the middle part of the mounting plate 210 so that the middle part of the mounting plate 210 is subjected to force, which is equivalent to shortening the free force length of the mounting plate 210 in disguised form, thereby preventing the mounting plate 210 from deforming and failing.

[0200] In addition, both ends of the mounting plate 210 are connected to the side plate 110. The side plate 110 is provided with a retaining ring 140, which is used to limit the lateral displacement of the mounting plate 210 so that the mounting plate 210 is not easy to shake laterally.

[0201] The double insurance of the arrangement enhances the reliability of the mounting plate 210, and the mounting plate 210 is less likely to deform and collapse.
