[0027] A baffle plate 10 is disposed at the left side of the tension spring 20 , and a pull ring 17 is disposed at the middle of the baffle plate 10 . The pull ring 17 is fixedly connected to the tension spring 20 .

[0028] A spring 11 is provided at the bottom of the telescopic rod 5 , a rod cavity 16 is provided between the spring 11 and the bottom of the telescopic rod 5 , and a telescopic hole 9 corresponding to the telescopic rod 5 is provided at the top of the bottom cover 2 .

[0029] A limiting block 21 is arranged at the middle position of the bottom of the bottom cover 2 , a gear cavity 7 is arranged at the middle position of the bottom of the upper cover 3 , and a motor cavity 18 is arranged at the bottom position of the motor 14 .

[0030] The motor 14 is powered by the upper battery pack 15, the door opener body 1 is bolted to the refrigerator through the bottom bolt hole 6, and the upper cover 3 and the bottom cover 2 are made of plastic structures.

[0031] In this embodiment, the utility model is specifically a vehicle-mounted refrigerator door opener. When in use, the motor 14 rotates to drive the second gear 13 at the bottom, and the second gear 13 drives the inner first gear 12 and the upper rotating rod 19 to rotate. The rotating rod 19 tightens the tension spring 20 inward, and the tension spring 20 pulls open the tilt angle baffle 10. The spring 11 in the rod cavity 16 will directly eject the telescopic rod 5 to close the refrigerator.

[0032] like Figure 1-3 As shown, a motor 14 is provided at the right side position inside the door opener body 1, a rotating rod 19 is provided at the left side position of the motor 14, a telescopic rod 5 is provided at the left side position of the rotating rod 19, a battery pack 15 is provided at the top position of the motor 14, a second gear 13 is provided at the bottom position of the motor 14, a first gear 12 is meshed and connected at the left side position of the second gear 13, the first gear 12 is fixedly connected to the rotating rod 19, a tension spring 20 is provided at the upper position of the rotating rod 19, a baffle 10 is provided at the left side position of the tension spring 20, a pull ring 17 is provided at the middle position of the baffle 10, the pull ring 17 is fixedly connected to the tension spring 20, a spring 11 is provided at the bottom position of the telescopic rod 5, a rod cavity 16 is provided between the spring 11 and the bottom position of the telescopic rod 5, and a telescopic hole 9 corresponding to the telescopic rod 5 is provided at the top position of the bottom cover 2.

[0033] Preferably, when in use, the motor 14 rotates to drive the second gear 13 at the bottom, and the second gear 13 drives the inner first gear 12 and the upper rotating rod 19 to rotate, and the rotating rod 19 tightens the tension spring 20 inward, and the tension spring 20 pulls open the tilt angle baffle 10, and the spring 11 in the rod cavity 16 will directly eject the telescopic rod 5 to close the refrigerator, thereby solving the problem that when the vehicle is driving, the existing vehicle-mounted refrigerator is subjected to bumps and vibrations, causing the refrigerator door to lose balance and become difficult to work normally, causing food inside the refrigerator to fall, or affecting the refrigerator's preservation effect.

[0034] like Figure 1 and Figure 2 As shown, a second gear 13 is disposed at the bottom of the motor 14 , a first gear 12 is meshedly connected at the left side of the second gear 13 , and a limit block 21 is disposed at the middle of the bottom of the bottom cover 2 .

[0035] Preferably, due to the precise meshing design of the gears, a higher transmission efficiency can be achieved. Compared with other transmission modes, gear transmission can reduce energy loss, provide more stable and reliable power output, ensure the precise movement of the internal motor 14, and maintain stable and reliable performance. A limit block 21 is set at the middle position at the bottom of the bottom cover 2. When the first gear 12 rotates to a certain position, the limit block 21 will collide with the fixed position, thereby limiting the rotation range of the first gear 12. This can prevent the first gear 12 from over-rotating or rotating to the wrong position, thereby protecting the normal operation of the mechanical device.

[0036] like Figure 1 and Figure 2 As shown, the motor 14 is powered by the upper battery pack 15, the door opener body 1 is bolted to the refrigerator through the bottom bolt hole 6, and the upper cover 3 and the bottom cover 2 are made of plastic structures.

[0037] Optionally, powered by the upper battery pack 15, the motor 14 of the door opener body 1 can operate independently of the vehicle's electrical system, which means that even if the vehicle is turned off or the power is cut off, the door opener body 1 can still operate normally, which provides greater convenience, especially when used in parking lots, camping sites or other places without power. Using the bottom bolt hole 6 to bolt to the refrigerator can provide a stable connection. The bolts usually have good tensile strength and shear strength, and can provide a reliable connection between the door opener body 1 and the refrigerator. This connection method can prevent the door opener body from accidentally falling off or loosening during use. The door opener body 1 made of plastic can reduce the weight of the entire device and reduce the burden. At the same time, it can effectively isolate the current and prevent the risk of electric shock.

[0038] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
