Description

Technical Field

[0001] This utility model relates to the field of vehicle compartment insulation technology, and in particular to a heat insulation device for a trailer caravan compartment. Background Technology

[0002] In towable caravans, thermal insulation is extremely important, directly affecting living comfort, energy efficiency, and equipment lifespan. Insulation layers effectively block external high or low temperatures, reducing temperature fluctuations inside the vehicle and preventing stuffiness after prolonged exposure to sunlight or coldness in winter.

[0003] In the prior art, such as Chinese Patent No. CN214057367U, a heat insulation device for a towable caravan includes a caravan body with a heat insulation plate placed on top of the caravan body. This heat insulation device for a towable caravan uses a pull plate to move a positioning plate into a placement compartment. Pulling the pull plate relative to each other causes a compression spring, a tension spring, and a buffer spring to be compressed, thus disengaging the positioning plate from its positioning groove. The user can then remove the heat insulation plate by moving it upwards. Pulling the pull plate again moves a support plate relative to each other, moving the positioning plate into the placement compartment. The user places the heat insulation plate between the fixed plates. Releasing the pull plate causes the compression spring, tension spring, and buffer spring to rebound in opposite directions, moving the support plate in opposite directions and locking the positioning plate into the positioning groove on the fixed plate. This completes the installation of the heat insulation plate, greatly improving the efficiency of heat insulation plate installation and removal and making it more convenient for users.

[0004] While the above-mentioned solution has the advantages mentioned above, its disadvantages are that the heat insulation design of the vehicle uses heat insulation panels, which increases the vehicle's weight and requires more fuel to maintain the vehicle's operation. At the same time, the heat insulation device lacks protective measures, and it is easily affected by rainwater seepage on rainy days. Utility Model Content

[0013] The technical effect of adopting the above-mentioned further solution is that the pulling column drives the heat insulation film body to extend, and limits it when the heat insulation film body retracts, so as to avoid it being completely rolled into the triangular space column.

[0014] In a preferred embodiment, the self-locking component includes:

[0015] A space slot is formed within the U-shaped block, and a push plate is embedded within the space slot;

[0016] A pressure rod is installed on the top of the push plate;

[0018] The technical effect of adopting the above-mentioned further solution is that the space slot provides displacement space for the push plate.

[0019] In a preferred embodiment, the self-locking component further includes:

[0020] Two springs are mounted on the top of the push plate;

[0021] Two limiting posts are installed at both ends of the top of the push plate;

[0022] One of the springs is located inside the space groove, and its other end is connected to the top of the inner wall of the space groove.

[0023] The technical effect of adopting the above-mentioned further solution is that the spring is used to control the rebound of the pulling column, thereby achieving the effect of automatic pop-out.

[0024] In a preferred embodiment, the self-locking component further includes:

[0025] Two clamping rods pass through both sides of the U-shaped block, and each clamping rod is fitted with a spring.

[0026] Two positioning holes are respectively opened at the bottom of the clamping rod;

[0027] The two ends of the second spring are respectively connected to one side of the inner wall of the U-shaped block and one side of the clamping rod, and the positioning hole can be fitted with the limiting post.

[0028] The technical effect of adopting the above-mentioned further solution is that the position of the clamping rod is fixed by the engagement of the positioning hole and the limiting post.

[0029] In a preferred embodiment, the protection component includes:

[0030] A track frame is installed on the triangular space column, and a T-shaped protective plate is slidably embedded in the track frame;

[0031] A fixing buckle is installed on one side of the T-shaped protective plate.

[0032] The technical effect of adopting the above-mentioned further solution is that the sliding effect of the T-shaped protective plate is used to protect the triangular space column.

[0033] In a preferred embodiment, the protection component further includes:

[0043] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0044] 1. This utility model involves manually pulling the pull column to one side to extend the heat insulation film body. The two ends of the pull column are pressed into two U-shaped blocks, causing the pressing rod to move downwards along the inner wall of the spatial groove. Spring one is thus in a stretched state. When the pressing rod is pressed down, it causes the push plate to shift to the same side, thereby causing the limiting column to be pulled out of the positioning hole. The clamping rod is then in a movable state and pushed to one side of the pull column by the elasticity of spring two, completing the clamping. In this design, the pull column is fixed by a self-locking component, allowing the heat insulation film body to achieve the heat insulation effect, reducing the counterweight of the vehicle body and decreasing fuel consumption.

[0045] 2. In this utility model, the T-shaped protective plate is pushed obliquely upward along the surface of the track frame. The fixing buckle, driven by the T-shaped protective plate, moves synchronously. One end of the buckle, moving along a straight path, lifts the J-shaped positioning strip. The limiting disc, driven by the J-shaped positioning strip, moves upward along the inner wall of the slot. The spring is compressed. When the fixing buckle aligns with one end of the J-shaped positioning strip, the spring, under its elastic effect, pushes the limiting disc back to its original position, causing one end of the J-shaped positioning strip to be embedded in the fixing buckle, thus fixing the position of the T-shaped protective plate. In this design, the position of the T-shaped protective plate is controlled by the protective components to ensure that the heat insulation film body is protected by the T-shaped protective plate within the retracted triangular space column, preventing damage from rainwater intrusion.

[0054] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0055] Example 1:

[0056] Please see Figures 1-6 This embodiment provides a heat insulation device for a towable caravan compartment, the specific concept of which is as follows:

[0057] A heat insulation device for a towable caravan includes a towable caravan body 1 and a triangular space column 101 installed on the top of the towable caravan body 1. The triangular space column 101 is equipped with a spring. The heat insulation device for the towable caravan also includes two U-shaped blocks 2 and two self-locking components.

[0058] Among them, the two U-shaped blocks 2, which play a fixing role, are installed on the top sides of the trailer caravan body 1.

[0059] Meanwhile, the two self-locking components are located inside the U-shaped block 2, which are used to automatically lock and clamp the object being pressed after being pressed.

[0060] In this design, the heat insulation device for the trailer caravan also includes: a heat insulation film body 102 and a pull column 103.

[0061] The heat insulation film body 102, which plays a role in heat insulation, is wound around a spring inside the triangular space column 101.

[0062] Meanwhile, the pulling column 103 for pulling action is installed on one side of the heat insulation film body 102.

[0063] As examples, in this embodiment, the self-locking component includes: a space slot 201, a pressing rod 203, two springs 204, two limiting posts 205, two clamping rods 206, and two positioning holes 208.

[0064] The space slot 201, which serves a spatial function, is located inside the U-shaped block 2, and the push plate 202 is embedded in the space slot 201.

[0065] Meanwhile, the pressure rod 203, which provides support, is installed on the top of the push plate 202.

[0066] It should be noted that one end of the pressing rod 203 passes through the top of the inner wall of the space groove 201 and is placed at the bottom of the pulling column 103.

[0067] In addition, two springs 204, which act as elastic springs, are installed on the top of the push plate 202.

[0068] To fix the position of the clamping rod 206, two limiting posts 205 are installed at both ends of the top of the push plate 202.

[0069] It should be noted that spring 204 is located inside the space groove 201, and its other end is connected to the top of the inner wall of the space groove 201.

[0070] In order to clamp the two sides of the pulling column 103, two clamping rods 206 are installed and pass through the two sides of the U-shaped block 2 respectively. Springs 207 are sleeved on both clamping rods 206.

[0071] The two positioning holes 208 that serve to fix the rod are respectively opened at the bottom of the clamping rod 206.

[0072] It should be noted that the two ends of the second spring 207 are connected to one side of the inner wall of the U-shaped block 2 and one side of the clamping rod 206, respectively, and the positioning hole 208 can be fitted with the limiting post 205.

[0073] In this embodiment, the pulling column 103 is first manually pulled to one side to extend the heat insulation film body 102. The two ends of the pulling column 103 are pressed into the two U-shaped blocks 2 respectively, so that the pressing rod 203 moves downward along the inner wall of the space groove 201 under this action. The spring 204 is thus in a stretched state. Then, when the pressing rod 203 is pressed down, it drives the push plate 202 to move to the same side, thereby causing the limiting column 205 to be pulled out from the positioning hole 208. The clamping rod 206 is in a movable state and is pushed to one side of the pulling column 103 by the elasticity of the spring 207, finally completing the clamping.

[0074] Example 2:

[0075] Please see Figures 1-6 Based on Example 1, this example provides a heat insulation device for a towed caravan compartment, the specific concept of which is as follows:

[0076] The thermal insulation device for the trailer caravan also includes a protective component located on the triangular space column 101 to shield and protect the interior of the triangular space column 101.

[0077] As examples, in this embodiment, the protective components include: a track frame 3, a fixing buckle 302, a slot 303, a J-shaped positioning strip 304, a limiting disc 305, and a spring 306.

[0078] The track frame 3, which serves to limit the movement trajectory, is installed on the triangular space column 101, and a T-shaped protective plate 301 is slidably embedded in the track frame 3.

[0079] Meanwhile, the fixing buckle 302, which plays a fixing role, is installed on one side of the T-shaped protective plate 301.

[0080] To provide installation space, a slot 303 is provided inside the triangular space column 101.

[0081] The J-shaped positioning strip 304, which plays a positioning role, is embedded in the groove 303.

[0082] It should be noted that one end of the J-shaped positioning strip 304 can be engaged with the fixing buckle 302.

[0083] In this design, a limiting disk 305 is also embedded in the slot 303.

[0084] In addition, the elastic spring 306 is sleeved on the limiting plate 305.

[0085] It should be noted that the spring 306 is located inside the slot 303, and its two ends are connected to one side of the inner wall of the slot 303 and one side of the limiting plate 305, respectively.

[0086] In this embodiment, the T-shaped protective plate 301 is first pushed obliquely upward along the surface of the track frame 3. The fixing buckle 302 moves synchronously under the drive of the T-shaped protective plate 301. One end of the buckle lifts the J-shaped positioning strip 304 along the trajectory of the linear movement. Then, the limiting plate 305 moves upward along the inner wall of the slot 303 under the drive of the J-shaped positioning strip 304. The spring 306 is compressed. When the fixing buckle 302 moves to correspond to one end of the J-shaped positioning strip 304, the spring 306 pushes the limiting plate 305 to reset under the elastic effect, so that one end of the J-shaped positioning strip 304 is embedded in the fixing buckle 302, and finally the position of the T-shaped protective plate 301 is fixed.

[0087] Working principle:

[0088] When heat insulation protection is required for the trailer caravan body 1, manually pull the pull column 103 to move it to one side, causing the heat insulation film body 102 to extend. Manually place both ends of the pull column 103 into the two U-shaped blocks 2 respectively, press the pull column 103, causing it to press the pressing rod 203 downward along the inner wall of the space groove 201, and stretch the spring 204. When the pressing rod 203 presses down, it drives the push plate 202 to move downward synchronously, thereby causing the limiting column 205 to disengage from the positioning hole 208. The clamping rod 206 is thus released from its limiting state. Under the elastic action of the second spring 207, it is pushed to one side of the pulling column 103, forming a fixing effect. When it is necessary to remove the pulling column 103, the two clamping rods 206 are manually pulled to both sides to release the fixing of the pulling column 103. Under the elastic action of the first spring 204, the pulling column 103 is pushed up by the pressing rod 203. The pushing plate 202 moves upward under the action of the pressing rod 203, thereby driving the limiting column 205 to reset and embed into the positioning hole 208.

[0089] After the pull column 103 is removed, the spring inside the triangular space column 101 drives the heat insulation film body 102 to roll back into the triangular space column 101. At this time, the J-shaped positioning strip 304 is pulled so that one end of it is disengaged from the fixing buckle 302, releasing the movement restriction of the T-shaped protective plate 301. Under natural gravity, the T-shaped protective plate 301 slides downward and covers the triangular space column 101 to provide protection. When the heat insulation film body 102 needs to be removed, push the T-shaped protective plate 301 so that it moves obliquely upward along the surface of the track frame 3. When the T-shaped protective plate 301 moves, it drives the fixing buckle 302 to move to the same side. One end of the fixing buckle 302 in this state lifts the J-shaped positioning strip 304. The J-shaped positioning strip 304 drives the limiting plate 305 to move upward along the inner wall in the slot 303 and squeezes the spring 306. When one end of the J-shaped positioning strip 304 corresponds to the fixing buckle 302, the spring 306 uses its own elasticity to push the J-shaped positioning strip 304 to move in the opposite direction, so that one end of it is embedded in the fixing buckle 302, thereby restricting the T-shaped protective plate 301.
