Description

Technical Field

[0001] This application relates to the technical field of RV insulation, and in particular to a molding process for an RV insulation box. Background Technology

[0002] A motorhome, also known as a "home on wheels," combines the functions of a "house" and a "vehicle," but its primary attribute is still that of a vehicle—a type of mobile vehicle equipped with the essential amenities for living. The insulated body of a motorhome typically uses a sandwich structure, consisting of two layers of metal panels and an insulation material in between.

[0003] In related technologies, for example, patent CN205327878U, published on 2016-06-22, discloses an insulated box structure, including four insulation boards that are directly processed from insulation materials and connected in sequence to form a four-panel body, and two single insulation boards that are positioned opposite each other. There are insulation board connecting sections between adjacent insulation boards to facilitate the corners of the four-panel body, and the two single insulation boards are bonded to the four-panel body.

[0004] Although it can achieve a heat preservation effect, the heat preservation effect cannot be adjusted, which limits its applicability. Summary of the Invention

[0005] To improve applicability, this application provides a molding process for a motorhome insulation box, employing the following technical solution:

[0006] A molding process for a motorhome insulated box body includes:

[0007] Insulated box shell molding process;

[0008] Inspection: Inspect the formed insulation box shell.

[0009] Polyurethane foam is used to form insulation boards, which are then installed on the inner wall of the calibrated and molded insulation box shell.

[0010] Internal and external surface finishing: finishing the internal and external surfaces of the insulation box shell;

[0011] The next step is to apply coating to the inner and outer surfaces of the insulation box shell.

[0012] After the insulation board is formed, the following process is also performed:

[0013] Insulation board pretreatment, heat-conducting plate and temperature-regulating component are installed inside the insulation board;

[0014] Laying the bottom layer involves laying metal floor plates on the inner wall of the RV, with multiple metal floor plates spliced ​​together to form the bottom layer;

[0015] A circulation pipe is laid on the bottom layer, the circulation pipe including an inlet pipe and an outlet pipe communicating with the inlet pipe;

[0016] An insulation layer is laid, and the insulation board is installed on the circulation pipe so that the insulation board abuts against the metal base plate, allowing heat exchange between the circulation pipe and the heat-conducting plate; multiple insulation boards are spliced ​​together to form an insulation layer; each insulation board corresponds to a metal base plate;

[0017] A surface layer is laid, and a metal panel is laid on the insulation board. The metal panel has connecting holes and operating holes. The temperature control component is used to connect or disconnect the heat conduction plate from the connecting holes. The operating holes are used to operate the temperature control component. The metal panel corresponds one-to-one with the insulation board. Multiple metal panels are spliced ​​together to form the surface layer.

[0018] By adopting the above technical solution, since a heat-conducting plate and a temperature-regulating component are pre-installed inside the insulation board, after the insulation board is installed in the circulation pipe, the circulation pipe and the heat-conducting plate exchange heat, and the insulation board locks in the temperature. By operating the temperature-regulating component, the heat-conducting plate can be connected to or disconnected from the connecting hole, so that when the circulation pipe is heating, heat is dissipated into the RV, and when the circulation pipe is cooling, cold energy is dissipated into the RV. This allows the insulation effect of the insulation board to be adjusted to improve its applicability.

[0019] Optionally, the pretreatment step of the insulation board specifically includes:

[0020] Mounting grooves are provided at both ends of the insulation board, and the insulation board is mounted on the circulation pipe through the mounting grooves;

[0021] A through-hole is made inside the insulation board, and the heat-conducting plate is installed inside the through-hole;

[0022] A portion of the bottom wall of the mounting groove is connected to the placement cavity;

[0023] A through-hole adjustment cavity is opened inside the insulation board, and the temperature adjustment component is installed inside the adjustment cavity;

[0024] A heat-conducting hole is made in the insulation board. The heat-conducting hole is connected to the placement cavity and the adjustment cavity. The connecting hole is coaxial with the heat-conducting hole and is the same size.

[0025] A connection hole is made in the insulation board, and the operating hole is coaxially arranged with the connection hole; the temperature control component is operated through the operating hole and the connection hole.

[0026] By adopting the above technical solution, the heat-conducting plate can be pre-inserted through the side wall of the insulation plate into the placement cavity to realize the installation of the heat-conducting plate; the temperature-regulating component can also be pre-inserted through the side wall of the insulation plate into the regulating cavity to realize the installation of the temperature-regulating component; after the installation of the heat-conducting plate and the temperature-regulating component is completed, the insulation plate is installed on the circulation pipe through the installation groove.

[0027] Optionally, the temperature control component includes:

[0028] The base plate is adjustable and has a rotating groove. A transition hole is formed in the rotating groove, and the transition hole is coaxially arranged with the heat conduction hole.

[0029] A rotating plate is installed in the rotating groove and is rotatably connected to the adjusting base plate. The rotating plate is provided with ventilation holes.

[0030] A rotating gear is coaxially and fixedly connected to the rotating plate;

[0031] The drive rack meshes with the rotating gear and is slidably connected to the rotating plate;

[0032] A drive component, mounted on the adjustment base plate, is used to drive the movement of the drive rack.

[0033] By adopting the above technical solution, the driving component drives the rack to move, the rack drives the rotating gear to rotate, thereby driving the rotating plate to rotate, thus adjusting the volume of the connection between the vent and the transition hole, and thus adjusting the insulation effect of the insulation board.

[0034] Optionally, the heat-conducting holes are opened on both sides of the adjustment base plate, and each heat-conducting hole corresponds to one of the rotating slots; two drive racks are provided, and the two drive racks correspond to the rotating plates diagonally opposite each other; the drive component is used to drive the independent movement of the two drive racks.

[0035] By adopting the above technical solution, since four heat conduction holes are set, four corresponding rotating slots are also required. This allows one drive rack to drive two rotating gears on one diagonal to move synchronously, thereby adjusting the volume of the connection between the two vent holes and the transition hole on the diagonal. Another drive rack drives two rotating gears on the other diagonal to move synchronously, thereby further adjusting the heat preservation effect of the insulation board.

[0036] Optionally, the drive component includes:

[0037] A rotating rod is provided, and the adjusting base plate has an adjusting groove. The rotating rod is rotatably connected to the bottom wall of the adjusting groove.

[0038] The driving plate has one end fixedly connected to the rotating rod, and the other end has a sliding groove.

[0039] The push block is slidably connected to the drive plate via the slide groove;

[0040] The blocking blocks are respectively fixedly connected to the opposing sidewalls of the two drive racks;

[0041] A push spring is installed in the sliding groove, with one end abutting against the inner wall of the sliding groove and the other end abutting against the push block.

[0042] By adopting the above technical solution, rotating the rotating rod clockwise or counterclockwise drives the plate to drive the pushing block to rotate, thereby driving the movement of the corresponding blocking block and thus realizing the movement of the driving rack.

[0043] Optionally, the temperature control component further includes:

[0044] An adjustment back plate is installed on the adjustment base plate and has the rotation groove, the adjustment groove, and the rack groove. The drive rack is installed in the rack groove and slides within the rack groove. The surface of the adjustment back plate is flush with the surface of the drive rack with the largest distance from the adjustment base plate.

[0045] By adopting the above technical solution, the drive rack and drive gear can be covered, thereby reducing the gap between the temperature control component and the insulation board, and thus improving the insulation effect of the insulation board.

[0046] Optionally, after the step of laying the surface layer, the method further includes:

[0047] For thermal insulation and reinforcement, the metal panel, the insulation board, and the metal base plate are connected to the RV body by bolts.

[0048] By adopting the above technical solutions, a stable connection between the bottom layer, insulation layer, and surface layer and the RV body is achieved.

[0049] Optionally, after the thermal insulation and reinforcement step, the method further includes:

[0050] Install the operating lever, insert one end of the operating lever into the rotating rod through the operating hole and the connecting hole to drive the rotating rod to rotate; and thread a rotating cap to the exposed end of the operating lever.

[0051] By adopting the above technical solution, it is convenient for people to operate the temperature control components directly through the control lever inside the RV.

[0052] Optionally, after the step of installing the operating lever, the method further includes:

[0053] Install ventilation columns on the metal panel. The ventilation columns abut against the rotating plate through the heat conduction holes and the transition holes. Ventilation holes are evenly distributed around the circumference of the ventilation columns.

[0054] By adopting the above technical solutions, the aesthetics are improved on the one hand, and large amounts of heat or cold are prevented from entering the interior of the RV at any time.

[0055] Optionally, the ventilated column includes:

[0056] The breathable column body has the breathable holes evenly distributed on it.

[0057] The dust cover is rotatably connected to the end face of the breathable column body via a rotating shaft, which is located at one end of the diameter of the end face of the breathable column body.

[0058] By adopting the above technical solution, when no heat preservation adjustment is performed, the dust cover can be rotated to close the vent holes, thereby reducing the amount of dust entering the vent column.

[0059] In summary, this application has at least the following beneficial effects:

[0060] 1. The purpose of pre-treating the insulation board and then laying the bottom layer, circulation pipe, insulation layer, and top layer in sequence is that, since a heat-conducting plate and temperature-regulating component are pre-installed inside the insulation board, after the insulation board is installed on the circulation pipe, the circulation pipe and the heat-conducting plate exchange heat, and the insulation board locks in the temperature. By operating the temperature-regulating component, the heat-conducting plate can be connected or disconnected from the connecting hole, so that when the circulation pipe is heating, heat is dissipated into the RV, and when the circulation pipe is cooling, cold energy is dissipated into the RV. This allows the insulation effect of the insulation board to be adjusted to improve its applicability.

[0061] 2. After laying the surface layer, insulation and reinforcement are carried out. After the insulation and reinforcement are carried out, the purpose of installing the control lever is to make it convenient for people to operate the temperature control components directly through the control lever inside the RV.

[0084] Specifically regarding S311:

[0085] Reference Figure 4 Mounting grooves 301 are formed at both ends of the insulation board 300, and a through placement cavity 302 is formed inside the insulation board 300. Part of the bottom wall of the mounting groove 301 is opened to connect the mounting groove 301 with the placement cavity 302. In this application, the bottom of the middle part of the mounting groove 301 can be retained, while the rest of the bottom wall is opened. Then, a through adjustment cavity 303 is formed inside the insulation board 300. Finally, heat conduction holes 304 are symmetrically formed on both sides of the insulation board 300, which are connected to the placement cavity 302 and the adjustment cavity 303. A connection hole 305 is also formed on the insulation board 300, which is connected to the adjustment cavity 303.

[0086] Specifically regarding S312:

[0087] Reference Figure 5The heat-conducting plate 310 is inserted through the side wall of the insulation plate 300 into the placement cavity 302. The heat-conducting plate 310 can be a metal plate or other material with good thermal and cold conduction effects. The temperature regulating component 320 is inserted through the side wall of the insulation plate 300 into the regulating cavity 303.

[0088] Expand description of temperature control component 320:

[0089] Reference Figure 6 and Figure 7 The temperature control assembly 320 may include an adjustment base plate 321, a rotating plate 322, a rotating gear 323, a drive rack 324, a drive component 325, and an adjustment back plate 326.

[0090] The adjustment base plate 321 is pre-machined, and rotating grooves 3211 are formed on it. These grooves are symmetrically located on both sides of one end of the adjustment base plate 321. Each rotating groove 3211 has a transition hole 3212 on its bottom wall, the size of which is the same as the heat-conducting hole 304. After the adjustment base plate 321 is installed in the adjustment cavity 303, the transition hole 3212 and the heat-conducting hole 304 are coaxial. A rotating plate 322 is installed in each rotating groove 3211 to allow it to rotatably connect to the adjustment base plate 321. The rotating plates 322 are pre-machined to prepare four rotating parts. A vent hole 3221 and a sliding groove are formed at the same position on each rotating plate 322, and a rotating gear 323 is coaxially fixedly connected to each rotating plate 322. Then, two drive racks 324 are placed on the adjusting base plate 321. One drive rack 324 is slidably connected to two rotating plates 322 on one diagonal through a sliding groove, and the other drive rack 324 is slidably connected to two rotating plates 322 on another diagonal through a sliding groove. The other drive rack 324 is located above the first drive rack 324. The drive racks 324 mesh with corresponding rotating gears 323.

[0091] The drive component 325 may include a rotating rod 3251, a driving plate 3252, a pushing block 3253, a blocking block 3254, and a pushing spring 3256.

[0092] Before installing the rotating plate 322 and the drive rack 324, an adjustment groove 3213 is formed on the adjusting base plate 321, and the connecting hole 305 communicates with the adjustment groove 3213. One end of the driving plate 3252 is fixedly connected to the rotating rod 3251, and a sliding groove is formed on the other end of the driving plate 3252. The push block 3253 is installed in the sliding groove so that the push block 3253 is slidably connected to the driving plate 3252 through the sliding groove. The push spring 3256 is installed in the sliding groove, with one end abutting against the inner wall of the sliding groove and the other end abutting against the push block 3253 to achieve the reset of the push block 3253. Then, the rotating rod 3251 is installed in the connecting hole 305 so that the rotating rod 3251 is rotatably connected to the adjusting base plate 321. After the rotating rod 3251 is installed, the blocking block 3254 is fixedly connected to the opposing side walls of the two driving racks 324, so that when the pushing block 3253 rotates, it can drive the movement of the blocking block 3254.

A rotation groove 3211, an adjustment groove 3213, and a rack groove 3261 are formed on the adjustment back plate 326. Then, the adjustment back plate 326 is installed on the adjustment base plate 321, and the drive rack 324 is embedded in the rack groove 3261 and moves within the rack groove 3261. The surface of the adjustment back plate 326 is flush with the surface of one drive rack 324, which has the largest distance from the adjustment base plate 321.

The circulation pipe 200 includes an inlet pipe and an outlet pipe, with the outlet pipe connected to the inlet pipe. After determining the position, install the inlet pipe and the outlet pipe respectively to realize the circulation of fluid within the circulation pipe 200. The fluid can be either gas or liquid.

[0098] Specifically regarding S34:

[0099] The insulation board 300 is installed on the circulation pipe 200, and the insulation board 300 abuts against the corresponding metal base plate 100. The circulation pipe 200 exchanges heat with the heat-conducting plate 310 through the connection between the mounting groove 301 and the placement cavity 302. Multiple insulation boards 300 are spliced ​​together to form an insulation layer.

The metal panel 400 is installed on the insulation board 300, with the connecting hole 410 coaxial with the heat conduction hole 304 and the operating hole 420 coaxial with the connection hole 305. Multiple metal panels 400 are spliced ​​together to form a surface layer.

[0102] Specifically regarding S36:

[0103] The metal panel 400, insulation board 300, and metal floor 100 are connected to the inner wall of the RV body with bolts.

[0104] Specifically regarding the S37:

[0105] Prepare an operating rod 500 in the same number as the insulation board 300. Insert one end of the operating rod 500 into the rotating rod 3251 through the operating hole 420 and the connecting hole 305 so that when the operating rod 500 rotates, it drives the rotating rod 3251 to rotate. Thread a rotating cap to the end of the operating rod 500 that is exposed to the outside.

[0106] Specifically regarding S38:

[0107] Prepare multiple sets of ventilation columns 600, equal in number to the metal panels 400, with each set consisting of four ventilation columns 600. Install the ventilation column sets 600 onto each metal panel 400 sequentially. Taking one set of ventilation columns 600 as an example, install four ventilation columns 600 onto the metal panel 400, ensuring that the ventilation columns 600 abut against the rotating plate 322 through the heat-conducting holes 304 and the transition holes 3212.

[0108] The ventilation column 600 includes a ventilation column body 610 and a dust cover 612. Ventilation holes 611 are evenly distributed circumferentially along the upper edge of the ventilation column body 610, and the ventilation holes 611 penetrate the ventilation column body 610.

[0109] It should be noted that the materials of the ventilated column body 610, the adjusting base plate 321, the adjusting back plate 326, and the rotating plate 322 are the same as those of the insulation board 300.

[0110] The implementation principle of this embodiment is as follows:

[0111] A metal base plate 100 is laid on the inner wall of the RV. Multiple metal base plates 100 are spliced ​​together to form the bottom layer. Then, according to the position of the mounting groove 301 of the insulation board 300, a circulation pipe 200 is laid on the metal base plate 100, and the insulation board 300 is installed on the circulation pipe 200 so that the insulation board 300 abuts against the metal base plate 100. Multiple insulation boards 300 are spliced ​​together to form an insulation layer. Then, a metal panel 400 is installed on the insulation board 300, and multiple metal panels 400 form the surface layer. The bottom layer, insulation layer and surface layer are connected to the inner wall of the RV body with bolts. Then, the operating lever 500 and the circulation cap are installed. Finally, the ventilation column 600 is installed, and the insulated box body is formed. When adjusting the heat preservation effect, the dust cover 612 is used to expose the vent 611. Then, the operating lever 500 is rotated so that the push block 3253 drives the blocking block 3254 to move, which in turn drives the drive rack 324 to drive the rotating gear 323 to rotate, thereby changing the communication area between the vent 3221 and the transition hole 3212, thus adjusting the heat preservation effect.

Any feature disclosed in this specification (including the abstract and drawings) may be replaced by other equivalent or similar features unless specifically stated otherwise. That is, unless specifically stated otherwise, each feature is only one example of a series of equivalent or similar features.
