Description

Technical Field

[0001] This utility model relates to the field of thermal insulation shells, specifically to a device shell with multiple layers of thermal insulation pads. Background Technology

[0002] In some household appliances, medical devices such as insulin coolers and blood coolers, as well as industrial equipment such as constant temperature control boxes and vehicle networking smart terminal housings, it is often necessary to attach thermal insulation pads to the inner wall of the housing to reduce heat exchange between the inside and outside of the housing, maintain stable internal temperature, improve buffer protection, ensure equipment function, or achieve energy saving.

[0003] In existing technologies, if multiple layers of insulation pads are required, adjacent pads are often directly bonded together with adhesive. However, long-term use is susceptible to thermal cycles and equipment vibrations, leading to weak adhesion, delamination, and a significant decrease in insulation performance. Furthermore, when the opening edge of the housing connects to other housings, additional sealing components are required to ensure a tight seal. The total amount of loose auxiliary materials used for the insulation pads and sealing components is considerable, and the assembly stability needs improvement. Utility Model Content

[0004] The problem to be solved by this utility model is to provide a device housing with multiple layers of heat insulation pads.

[0005] To solve the above problems, this utility model provides a device housing with multiple layers of insulation pads. To achieve the above objectives, the technical solution adopted by this utility model to solve its technical problems is as follows: A device housing with multiple layers of insulation pads includes: an outer shell having a recess; a bottom insulation pad covering the bottom surface of the recess; side insulation pads covering the side walls of the recess, wherein the side insulation pads are multiple layers; and adhesive tape for bonding the inner walls of the side insulation pads, the top edges of the side insulation pads, and the edges of the outer shell where the opening of the recess is located; wherein the side insulation pads are in a closed loop with their ends joined together, forming a seam at the joint, and the adhesive tape covers a portion of the seam.

[0006] As a further improvement of this utility model, the cross-sectional trajectory of the tape is L-shaped, and the tape includes a first adhesive portion and a second adhesive portion, wherein the first adhesive portion and the second adhesive portion are perpendicular to each other.

[0007] As a further improvement of this utility model, the tape consists of two strips, which are arranged parallel to each other on both sides of the center of the outer shell.

[0008] As a further improvement of this utility model, the side insulation pad includes an outer surrounding pad and an inner surrounding pad. The inner wall of the outer surrounding pad is attached to the outer wall of the inner surrounding pad, and the outer wall of the outer surrounding pad is attached to the inner wall of the recess. The outer surrounding pad forms a first seam at its end-to-end joint, and the inner surrounding pad forms a second seam at its end-to-end joint. The first seam and the second seam do not overlap. The tape covers a portion of the second seam.

[0009] As a further improvement of this utility model, the bottom insulation pad includes a first bottom pad and a second bottom pad that are attached to each other. The first bottom pad completely covers the bottom surface of the recess, the area of ​​the second bottom pad is smaller than the area of ​​the first bottom pad, and the second bottom pad is attached to the middle of the upper surface of the first bottom pad.

[0010] As a further improvement of this utility model, a stepped surface is formed between the edge of the second bottom pad and the upper surface of the first bottom pad, the bottom edge of the side insulation pad is in contact with the stepped surface, and the width of the stepped surface is equal to the sum of the thicknesses of all the side insulation pads.

[0014] As a further improvement of this utility model, the first adhesive portion extends vertically, the second adhesive portion extends horizontally, and the width of the second adhesive portion is less than the sum of the wall thickness of the outer shell and the thickness of the side insulation pad.

[0015] The beneficial technical effects of using the equipment housing with multi-layer insulation pads described in this application are: By setting a bottom insulation pad that covers the bottom of the recess and a multi-layered side insulation pad, the heat exchange between the inside and outside of the equipment housing can be reduced comprehensively, effectively maintaining the internal temperature of the housing and meeting the usage requirements of temperature-sensitive equipment, while improving the housing's ability to buffer and protect internal components.

[0016] By using tape to bond the inner wall and top edge of the side insulation pad to the edge of the outer shell at the opening of the recess, the adhesion between the multiple layers of side insulation pads and between the insulation pad and the outer shell can be strengthened, preventing the insulation pad from delaminating and falling off during long-term use. The tape can also cover the joints formed by the end of the side insulation pads, ensuring the assembly firmness between the insulation pads and between the insulation pad and the outer shell.

[0017] The tape, applied to the edge of the housing opening, provides sealing and cushioning during assembly with other components, eliminating the need for additional seals, sealing rings, or gaskets, thus reducing the amount of miscellaneous materials and simplifying the assembly process.

[0021] The present invention will be further described in detail below with reference to specific embodiments: To achieve the purpose of this utility model, a device housing with multiple layers of insulation pads includes: an outer shell 1 having a recess 101; a bottom insulation pad covering the bottom surface of the recess 101; side insulation pads covering the side walls of the recess 101, the side insulation pads being multiple layers; and adhesive tape 6 bonding the inner walls of the side insulation pads, the top edge of the side insulation pads, and the edge of the outer shell 1 where the opening of the recess is located. The side insulation pads are in a closed-loop state with their ends joined together, forming a seam at the joint, and the adhesive tape 6 covers a portion of the seam, meaning the adhesive tape 6 covers at least a portion of the seam.

[0022] The bottom insulation pad and the side insulation pad together surround the receiving cavity 7. The volume of the receiving cavity 7 is smaller than the volume of the lower recess 101. The opening direction of the receiving cavity 7 is the same as the opening direction of the lower recess 101.

[0025] The beneficial effects of adopting the above technical solution are: the outer shell 1 can be an integral metal shell, and the thermal insulation pad on the inner wall of the metal shell can play the role of isolating temperature and buffering protection, thereby protecting the internal equipment of the outer shell 1 in a relatively stable working environment for a long time.

[0026] The shape of the bottom and side insulation pads means they can be cut and bent from flat insulation pad material, eliminating the need for special customization and reducing manufacturing costs. The combined bottom and side insulation pads can cover all surfaces of the recess 101, providing a wide coverage area.

[0027] In addition, multi-layer insulation pads provide better insulation than single-layer ones. The relatively thinner single-layer insulation pads are also easier to bend and reshape in a closed loop.

[0028] The tape 6 serves a dual purpose. First, its adhesive strength bonds the edges of the multi-layered side insulation pads to one side and to the edge of the opening in the outer shell 1, ensuring the fit of the side insulation pads. Second, the portion of the tape directly bonded to the outer shell 1 acts as a thin cushioning pad. When the outer shell 1 is assembled with other shells, this portion of the tape 6 is sandwiched in the middle, improving sealing and cushioning.

[0029] In some other embodiments of this utility model, the cross-sectional trajectory of the tape 6 is L-shaped, and the tape 6 includes a first adhesive portion 601 and a second adhesive portion 602, with the first adhesive portion 601 and the second adhesive portion 602 being perpendicular to each other.

[0031] In some other embodiments of this utility model, there are two tapes 6, which are arranged parallel to each other on both sides of the centroid of the outer shell 1 along the length of the tape 6.

[0032] The advantages of adopting the above technical solution are: this symmetrical layout can balance the adhesive force and the pasting method is also simple.

The inner wall of the outer surrounding pad 4 is attached to the outer wall of the inner surrounding pad 5, and the outer wall of the outer surrounding pad 4 is attached to the inner wall of the recess 101. The outer surrounding pad 4 forms a first seam 401 at its end-to-end joint, and the inner surrounding pad 5 forms a second seam 501 at its end-to-end joint. The first seam 401 and the second seam 501 do not overlap. Adhesive tape 6 covers a portion of the second seam 501.

[0034] The beneficial effects of adopting the above technical solution are: the first joint 401 and the second joint 501 do not overlap, which can reduce heat loss at this point. The tape 6 covers a portion of the second joint 501, further strengthening the joint sealing and firmness of the inner surrounding pad 5 and avoiding weak points in the insulation layer.

[0035] In some other embodiments of this utility model, the bottom insulation pad includes a first bottom pad 2 and a second bottom pad 3 that are attached to each other. The first bottom pad 2 completely covers the bottom surface of the recess 101, the area of ​​the second bottom pad 3 is smaller than the area of ​​the first bottom pad 2, and the second bottom pad 3 is attached to the middle of the upper surface of the first bottom pad 2.

[0036] The beneficial effects of adopting the above technical solution are: forming a double-layer insulation structure and enhancing the bottom insulation effect.

[0037] In some other embodiments of the present invention, a stepped surface 201 is formed between the edge of the second bottom pad 3 and the upper surface of the first bottom pad 2, and the bottom edge of the side insulation pad contacts the stepped surface 201. The width of the stepped surface 201 is equal to the sum of the thicknesses of all the side insulation pads.

[0038] The beneficial effects of adopting the above technical solution are: ensuring that the bottom edge of the side insulation pad is in stable contact with the step surface 201, preventing the side insulation pad from shifting or being suspended, and improving the overall structural stability.

[0039] In some other embodiments of this utility model, the side of the second bottom pad 3 facing the first bottom pad 2 has an adhesive surface.

[0040] The beneficial effects of adopting the above technical solution are: it enables the second bottom pad 3 to automatically bond with the first bottom pad 2, simplifies the assembly process, enhances the fit between the two pads, avoids relative sliding or separation, and improves the stability of the bottom insulation layer.

[0041] In some other embodiments of this utility model, the outer wall of the outer surrounding pad has an adhesive surface, and the outer wall of the inner surrounding pad has an adhesive surface.

[0042] The beneficial effects of adopting the above technical solution are: the outer surrounding pad 4 and the inner wall of the recess 101 are automatically bonded, the inner surrounding pad 5 and the inner wall of the outer surrounding pad 4 are automatically bonded, the installation efficiency is improved and a tight fit is ensured, gaps and heat loss are reduced, and the insulation effect is enhanced.
