Description

Technical Field

[0001] This utility model relates to the field of RV refrigerator technology, and in particular to a vibration-resistant RV refrigerator device suitable for multi-terrain mobile environments. Background Technology

[0002] RV refrigerators are devices installed in RVs to store and preserve food and beverages. They are powered by DC or AC power and are designed to be shock-resistant and energy-efficient, adaptable to RV travel. Some models also support gas power. They can maintain low temperatures in different environments to meet the food preservation needs of RV travel. Their capacity and functions vary depending on the type of RV and user needs, making them an important part of RV living facilities.

[0003] Vibration-resistant RV refrigerator units, suitable for multi-terrain mobile environments, employ a special shock-absorbing and buffering structure in their structural design. This effectively absorbs and rebounds the shaking forces generated by vehicle movement, reducing the impact on the refrigerator. Some models are also equipped with multi-stage damping and shock absorption components, including rubber shock-absorbing pads, damping rubber rings, and dampers at different locations, damping and reducing bumps and vibrations at multiple levels to ensure refrigerator stability. In terms of details, vibration-resistant RV refrigerator units often feature safety switches on the cabinet door handles to prevent accidental opening during travel. The interior uses materials such as plastic inner liner and door frame to enhance durability. They employ fully enclosed compressors with low-voltage protection, power fuses, and automatic reverse polarity protection. Yes, it can be equipped with a dynamic ventilation wire tube condenser and a continuously adjustable temperature control system to ensure stable operation in complex road conditions and harsh weather environments. However, the vibration damping structure affects the layout of the cooling fan or heat sink, resulting in reduced heat dissipation efficiency. Especially in high-temperature environments, this increases the compressor load and may even trigger shutdown protection. In existing technologies, by separating the compressor and condenser heating components from the refrigerator body and connecting them through flexible pipelines, the heat dissipation module can be independently designed in a well-ventilated location in the RV, avoiding the limitation of heat dissipation space by the vibration damping structure. However, long-term vibration can cause the fixing bolts between the refrigerator and the mounting base to loosen or even slide, increasing the probability of injuring passengers or damaging the interior facilities. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a vibration-resistant RV refrigerator device suitable for multi-terrain mobile environments, aiming to improve the problem in the prior art where long-term vibration causes the fixing bolts between the refrigerator and the mounting base to loosen or even slide, increasing the probability of injuring passengers or damaging the facilities inside the vehicle.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a vibration-resistant RV refrigerator device suitable for multi-terrain mobile environments, comprising a mounting box, wherein a refrigerator body is disposed inside the mounting box, and buffer mechanisms are installed at both the upper and lower ends of the mounting box, the buffer mechanisms being used to achieve a buffering effect on the refrigerator body; a clamping mechanism is installed on the rear side of the mounting box, the clamping mechanism being used to fix the refrigerator body; the buffer mechanism includes multiple sliding grooves, the multiple sliding grooves being respectively opened at the upper and lower ends of the inner side of the mounting box and the upper and lower ends of the refrigerator body; a second spring is installed inside the sliding groove, and a moving plate is fixedly connected to the left and right ends of the second spring; a rotating short column is rotatably connected to the adjacent side of the two moving plates; a connecting long plate is rotatably connected to the middle of the rotating short column; a connecting short column is rotatably connected to the middle of the connecting long plate; and multiple first springs are fixedly connected at equal intervals at both the upper and lower ends of the mounting box.

[0022] 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.

[0023] Reference Figure 1 , Figure 4 and Figure 5 This utility model provides an embodiment of a vibration-resistant RV refrigerator device suitable for multi-terrain mobile environments, comprising a mounting box 1, a refrigerator body 5 disposed inside the mounting box 1, and buffer mechanisms 3 installed at both the upper and lower ends of the mounting box 1 to achieve a buffering effect on the refrigerator body 5. A clamping mechanism 2 is installed on the rear side of the mounting box 1 for fixing the refrigerator body 5. The buffer mechanism 3 includes multiple sliding grooves 302, which are respectively opened at the upper and lower ends of the inner side of the mounting box 1 and the upper and lower ends of the refrigerator body 5. A second spring 303 is installed inside the sliding groove 302. Movable plates 307 are fixedly connected to both the left and right ends of the device. A rotating short column 304 is rotatably connected to the adjacent side of the two movable plates 307. A connecting long plate 305 is rotatably connected to the middle of the rotating short column 304. A connecting short column 306 is rotatably connected to the middle of the connecting long plate 305. Multiple first springs 301 are fixedly connected at equal intervals to the upper and lower ends of the inside of the mounting box 1. The installation of the first springs 301 can achieve an auxiliary buffering effect, thereby reducing the probability of damage to the device. The other ends of the multiple middle movable plates 307 are slidably connected to the upper and lower ends of the refrigerator body 5, respectively. The other end of the first spring 301 is fixedly connected to the refrigerator body 5.

[0024] Specifically, when the RV moves and vibrates on complex terrain, the moving plate 307 connected to the second spring 303 will be subjected to force due to vibration through the opening of multiple sliding grooves 302, causing it to slide within the sliding grooves 302. The rotating short column 304 on the moving plate 307 will cause the connecting long plate 305 to rotate around it, thereby causing the connecting short column 306 to also rotate. Through the extension and contraction of the second spring 303, the refrigerator body 5 is buffered. At the same time, the auxiliary buffering effect of multiple first springs 301 ensures that the position of the refrigerator body 5 remains stable during vibration, resisting the vibration caused by the movement on complex terrain and preventing damage to the device.

[0025] Reference Figure 1 , Figure 4 and Figure 6 The clamping mechanism 2 includes a square groove 209, which is located in the middle of the rear side of the mounting box 1. A mounting block 202 is fixedly connected to the middle of the square groove 209. A bidirectional threaded rod 201 is rotatably connected to the outer side of the mounting block 202. Movable square plates 203 are threadedly connected to the left and right ends of the outer side of the bidirectional threaded rod 201. A clamping plate 204 is fixedly connected to the front side of the movable square plate 203. Sliding grooves 205 are provided at the front and rear ends of adjacent sides of the two clamping plates 204. Through the installation of the clamping plates 204, the refrigerator body 5 can be clamped and fixed. The middle of the sliding groove 205 is slidably connected... The slider 206 is connected to the left and right ends of the bidirectional threaded rod 201, and the limiting round plate 207 is fixedly connected to both ends. The driving component 208 is installed on the opposite side of the two limiting round plates 207. The driving component 208 includes a rotating round rod 2082, which is fixedly connected to the outside of the limiting round plate 207. A turntable 2081 is fixedly connected to the outside of the driving component 208. Multiple heat dissipation slots 4 are equidistantly opened on the rear bottom of the mounting box 1. The outer sides of the two sliders 206 are fixedly connected to the left and right ends of the refrigerator body 5 respectively. The opening of the heat dissipation slots 4 facilitates the heat dissipation of the refrigerator body 5.

[0026] Specifically, by rotating the turntable 2081, the rotating rod 2082 is driven to rotate. The rotation of the rotating rod 2082 causes the limiting plate 207 to rotate accordingly, causing the bidirectional threaded rod 201 to rotate on the mounting block 202. Since the threads on the left and right sides of the bidirectional threaded rod 201 are opposite, when rotating, the outer movable plate 203 will move in the opposite direction along the bidirectional threaded rod 201, thereby causing the clamping plate 204 to move synchronously accordingly. When the clamping plate 204 approaches the refrigerator body... At 5 o'clock, the sliding grooves 205 on both sides of the clamping plate 204 allow the slider 206 to slide in the middle, thereby making fine adjustments according to the shape of the refrigerator body 5, so that the two clamping plates 204 can firmly fix the refrigerator body 5 in the mounting box 1. If the refrigerator body 5 needs to be disassembled, simply rotate the turntable 2081 in the opposite direction, and the clamping plate 204 will be released, which facilitates the installation and disassembly of the refrigerator body 5. In addition, the opening of the sliding groove 205 provides a buffer space for this device to reduce the probability of damage to the device under vibration.

[0027] Reference Figure 1 , Figure 2 and Figure 3 The refrigerator body 5 has doors 6 installed on both the left and right sides of the front side. A handle 7 is fixedly connected to the middle of the front side of the door 6. A connecting plate 9 is installed on the top of the refrigerator body 5. A bolt 10 is threadedly connected to the middle of the connecting plate 9. The bottom of the front side of the connecting plate 9 is threadedly connected to the top of the door 6. A display screen 8 is installed on the front side of the left door 6.

[0028] Specifically, the installation of handle 7 facilitates the opening and closing of the door 6, the installation of connecting plate 9 ensures that the door 6 and the refrigerator body 5 can be securely installed, and the installation of display screen 8 facilitates user operation.

[0029] Working principle: When the RV vibrates during multi-terrain movement, the opening of multiple sliding grooves 302 causes the moving plate 307 connected to the second spring 303 to slide within the sliding grooves 302 due to the vibration. The rotating short column 304 on the moving plate 307 drives the connecting long plate 305 to rotate around it, which in turn causes the connecting short column 306 to rotate as well. Through the extension and retraction of the second spring 303, the refrigerator body 5 is buffered. At the same time, the auxiliary buffering of multiple first springs 301 stabilizes the position of the refrigerator body 5 during the buffering process, thereby resisting the vibration caused by multi-terrain movement.

[0030] By rotating the turntable 2081, the rotating rod 2082 is driven to rotate, which in turn drives the limiting plate 207 to rotate, thereby causing the bidirectional threaded rod 201 to rotate on the mounting block 202. Since the left and right threads of the bidirectional threaded rod 201 are opposite, when it rotates, the outer movable plate 203 will move towards or away from the bidirectional threaded rod 201, thereby causing the clamping plate 204 fixedly connected to the front of the movable plate 203 to move accordingly. When the clamping plate 204 approaches the refrigerator body 5... Within the sliding grooves 205 opened at the front and rear ends of the adjacent side of the clamping plate 204, the slider 206 can slide in the middle of the sliding groove 205, and finely adjust the clamping position according to the shape of the refrigerator body 5 until the two clamping plates 204 firmly clamp the refrigerator body 5 in the mounting box 1; if it is necessary to disassemble the refrigerator body 5, simply rotate the turntable 2081 in the opposite direction to release the clamping plate 204. Furthermore, the opening of the sliding groove 205 provides a certain buffer space when the device is subjected to vibration, reducing the probability of damage to the device.

[0031] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
