Description

Technical Field

[0001] This utility model belongs to the field of graphene heating element packaging technology, specifically referring to a graphene heating element packaging structure. Background Technology

[0002] The graphene heating element encapsulation structure is designed to protect the graphene heating element and facilitate its installation and fixation. During the use of the graphene heating element, it is subjected to harsh environments such as high temperature and high humidity for a long time, which will cause the material to age and reduce its heating performance. In addition, as the usage time increases, the resistance of the graphene heating element may change, thereby affecting the current flow and heat generation. Therefore, it needs to be replaced regularly.

[0003] Existing graphene heating element encapsulation structures, such as the one disclosed in application number CN202323566685.X, sandwich the graphene heating element body between two heat-conducting sheets. The first and second encapsulation plates can encapsulate and fix the graphene heating element body, the two heat-conducting sheets, and the insulating ring, increasing the stability and safety of the device. Furthermore, by unscrewing multiple bolts from multiple threaded holes, the two first and two second encapsulation plates can be disassembled, allowing the graphene heating element body to be removed from inside the insulating ring for maintenance.

[0004] However, in practical applications, the existing encapsulation structure has a large number of components, requiring repeated and multiple bolt tightening during disassembly, which is inefficient and complex. Furthermore, the overall structural dimensions are fixed, and when encapsulating graphene heating elements of different sizes, corresponding encapsulation structures need to be set according to the size of the graphene. The applicability of a single encapsulation structure is small, resulting in high production and mold opening costs. In particular, the lack of connection between the encapsulation boards in the existing encapsulation structure leads to poor stability of the overall structure. Therefore, we propose a graphene heating element encapsulation structure to solve the above problems. Utility Model Content

[0005] In order to overcome the shortcomings of the prior art, this utility model provides a graphene heating element packaging structure, which effectively solves the problems of complex disassembly and assembly and low efficiency of the existing graphene heating element packaging structure, and solves the problems of poor stability of the connection between the components of the existing packaging structure, as well as the fixed size structure and limited applicability.

[0006] The technical solution adopted by this utility model is as follows: The graphene heating element encapsulation structure proposed by this utility model includes an encapsulation plate one and an encapsulation plate two. The two ends of one side wall of the encapsulation plate are fixed with a locking block. The two ends of the encapsulation plate two are provided with a locking groove, and the encapsulation plate two is locked onto the locking block of the encapsulation plate one through the locking groove. The encapsulation plate two is provided with four groups, which are symmetrical in pairs. The adjacent groups of encapsulation plates two are connected by an adjustable spacing splitting mechanism. The inner walls of the encapsulation plate one and the encapsulation plate two are provided with a locking and protective structure.

[0007] As an improvement to this solution, a limiting plate is fixed on the inner wall of the second encapsulation plate, and a connecting plate is slidably connected to the limiting plate. The connecting plate is located between the two sets of second encapsulation plates. Sliding grooves are provided at both the upper and lower ends of the second encapsulation plate, and sliding shafts are fixed at both the upper and lower ends of the connecting plate. The sliding shafts are slidably connected in the sliding grooves.

[0008] As an improvement to this solution, the distance adjustment and splitting mechanism includes a clamping plate, a fixing bolt, a fixing plate, and a double-ended screw. The fixing bolt is plugged into and connected to the connecting plate and is located in the middle of the connecting plate. The fixing bolt passes through the clamping plate and is threaded onto the connecting plate. The fixing plate is fixed to the inner wall of the clamping plate. The double-ended screw is rotatably connected to the fixing plate and passes through the fixing plate. A connecting fixing block is fixed on the inner wall of the second encapsulation plate, and the connecting fixing block is threaded onto the double-ended screw.

[0009] As an improvement to this solution, a worm gear is fixedly connected in the middle of the double-ended screw, and a worm is rotatably connected to the clamping plate. One end of the worm is inserted and pulled into the connecting plate and is rotatably connected to the connecting plate. An adjusting nut is fixed to the other end of the worm and is located on the outside of the clamping plate. A limiting ring is fixed on the worm and is rotatably connected to the inside of the side wall of the clamping plate.

[0010] As an improvement to this solution, the clamping and protective structure includes an elastic plate, a first fixing pad, and a second fixing pad. The elastic plate is fixed to the upper and lower ends of the inner side of the first encapsulation plate, the first fixing pad is fixed to both ends of the inner wall of the first encapsulation plate, and the second fixing pad is fixed to the end of the inner wall of the second encapsulation plate near the slot.

[0011] As an improvement to this solution, the limiting plate and the double-headed screw are arranged in parallel, the elastic plate and the second encapsulation plate are arranged perpendicularly, and the worm gear is located between the clamping plate and the connecting plate.

[0012] As an improvement to this solution, both the first and second encapsulation plates are U-shaped thin plates, and the end of the second encapsulation plate near the slot is L-shaped, while the elastic plate is an arc-shaped thin plate.

[0013] As an improvement to this solution, the limiting plate has an L-shaped cross-section, and the card plate has a U-shaped cross-section.

[0014] As an improvement to this solution, both the first fixing pad and the second fixing pad are made of rubber.

[0015] The beneficial effects of this utility model achieved by adopting the above structure are as follows:

[0016] 1. It is equipped with a spacing adjustment and splitting mechanism. The spacing between the two packaging plates can be adjusted by rotating the double-headed screw. This allows it to adapt to the packaging of graphene heating elements of different lengths by simply replacing the packaging plate of different lengths, thus reducing the cost of production mold opening.

[0017] 2. The adjustable splitting mechanism allows for easy assembly and disassembly by simply turning the adjusting nuts on both sides. Combined with the clips on the first packaging board and the slots on the second packaging board, it enables quick installation and disassembly of the packaging structure and improves the stability of the connection between the various components of the packaging structure.

[0018] 3. It is equipped with a clamping and protective structure. Utilizing flexible fixing pads and elastic plates, it can not only clamp and fix the graphene heating element to prevent gaps from causing shaking, but also use the properties of the material itself to provide better protection for the graphene heating element and play a role in preventing drop.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0027] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, the present invention proposes a graphene heating element encapsulation structure, including an encapsulation plate 1 and an encapsulation plate 2. The two ends of the sidewall of the encapsulation plate 1 are fixed with locking blocks 3, and the two ends of the encapsulation plate 2 are provided with locking grooves 4. The encapsulation plate 2 is locked onto the locking blocks 3 of the encapsulation plate 1 through the locking grooves 4. The encapsulation plate 2 has four sets, symmetrically arranged in pairs. Adjacent sets of encapsulation plates 2 are connected by an adjustable spacing splitting mechanism 5. The inner walls of the encapsulation plate 1 and the encapsulation plate 2 are provided with a locking and protective structure 6. A limiting plate 7 is fixed to the inner wall of the encapsulation plate 2. A connecting plate 8 is slidably connected to the limiting plate 7, and the connecting plate 8 is located between two sets of encapsulation plates 2. The upper and lower ends of the encapsulation plate 2 are provided with sliding grooves 9, and the upper and lower ends of the connecting plate 8 are fixed with sliding shafts 10, which are slidably connected within the sliding grooves 9.

[0028] To enable rapid assembly and disassembly of the encapsulation structure and to accommodate the installation of graphene heating elements of different sizes, the adjustable splitting mechanism 5 includes a clamping plate 11, a fixing bolt 12, a fixing plate 13, and a double-ended screw 14. The fixing bolt 12 is plugged into and connected to the connecting plate 8 and is located in the middle of the connecting plate 8. The fixing bolt 12 passes through the clamping plate 11 and is threaded onto the connecting plate 8. The fixing plate 13 is fixed to the inner wall of the clamping plate 11. The double-ended screw 14 is rotatably connected to the fixing plate 13 and passes through the fixing plate 13. A connecting fixing block 15 is fixed on the inner wall of the encapsulation plate 2 and is threaded onto the double-ended screw 14.

[0029] like Figure 2 , Figure 3 and Figure 5As shown, a worm gear 16 is fixedly connected in the middle of the double-ended screw 14, and a worm 17 is rotatably connected to the clamping plate 11. One end of the worm 17 is inserted and pulled into the connecting plate 8 and is rotatably connected to the connecting plate 8. An adjusting nut 18 is fixed to the other end of the worm 17 and is located on the outside of the clamping plate 11. A limiting ring 19 is fixed on the worm 17 and is rotatably connected to the side wall of the clamping plate 11.

[0030] like Figure 1 , Figure 2 and Figure 4 As shown, the clamping protection structure 6 includes an elastic plate 20, a fixing pad 1 21 and a fixing pad 22. The elastic plate 20 is fixed to the upper and lower ends of the inner side of the encapsulation plate 1, the fixing pad 1 21 is fixed to the two ends of the inner wall of the encapsulation plate 1, and the fixing pad 22 is fixed to the end of the inner wall of the encapsulation plate 2 near the slot 4.

[0031] like Figure 2 and Figure 4 As shown, the limiting plate 7 and the double-headed screw 14 are arranged in parallel, the elastic plate 20 and the encapsulation plate 2 are arranged perpendicularly, and the worm gear 16 is located between the clamping plate 11 and the connecting plate 8; both the encapsulation plate 1 and the encapsulation plate 2 are thin plates with a U-shaped cross section, and the end of the encapsulation plate 2 near the slot 4 is L-shaped, while the elastic plate 20 is an arc-shaped thin plate; the limiting plate 7 has an L-shaped cross section, and the clamping plate 11 is U-shaped.

[0032] Both the first fixing pad 21 and the second fixing pad 22 are made of rubber.

[0033] In practical use, rotating the adjusting nut 18 simultaneously drives the worm gear 17, and the worm wheel 16 meshing with the worm gear 17 drives the double-ended screw 14 to rotate. The connecting fixing block 15 threaded onto the double-ended screw 14 drives the encapsulation plate 2 to move to both ends under the guidance of the limiting plate 7 and the sliding shaft 10, thereby causing the locking block 3 to be pulled out of the locking slot 4. At this time, the encapsulation plate 1 can be pulled out from the graphene heating element to both sides. After replacing the graphene heating element, the corresponding encapsulation plate 1 is snapped onto both ends of the graphene heating element, and then the encapsulation plate 2 with the adjustable spacing splitting mechanism 5 is attached to the graphene heating element. On the other two sides of the graphene heating element, rotating the adjusting nut 18 in the opposite direction will bring the two sets of encapsulation plates 2 on the same side closer together until the slot 4 is engaged with the block 3. At this time, the graphene heating element is clamped by the action of the fixing pad 1 21 and the fixing pad 2 22, and the heat-conducting sheets on the upper and lower sides of the graphene heating element are pressed together by the elastic plate 20 to keep them in close contact. When encountering an impact, the elasticity of the elastic plate 20, the fixing pad 1 21 and the fixing pad 2 22 themselves will reduce the impact, thereby playing an auxiliary protective role. The above is the usage process of the entire graphene heating element encapsulation structure.

[0034] The present invention and its embodiments have been described above. This description is not restrictive, and the accompanying drawings are only one embodiment of the present invention; the actual structure is not limited thereto. In conclusion, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the inventive spirit of the present invention, such designs should fall within the protection scope of the present invention.
