Technical Field
[0001] This invention relates to the field of vehicle-mounted refrigerator technology, and more particularly to a multi-structure integrated improved vehicle-mounted refrigerator adapted for trucks. Background Technology
[0002] In the trucking sector, the increasing demand for cold chain logistics and the diversification of transportation scenarios have placed higher demands on the performance and space utilization efficiency of vehicle-mounted refrigerators. Traditional condenser layouts for vehicle-mounted refrigerators have significant drawbacks. Most condensers are located inside the refrigerator, which severely occupies the limited internal space, preventing the refrigerated compartment from maximizing its effective volume. For example, when transporting goods with high space requirements, the space occupied by the condenser restricts the volume of cargo that can be loaded, impacting transportation efficiency.
[0003] Meanwhile, most truck-mounted refrigerators currently used in the freight transport sector adopt a traditional external layout design. This type of layout places the refrigerator control panel on the outside of the device, directly exposed to easily accessible areas in the driver's cab or cargo compartment, lacking an effective anti-accidental touch protection mechanism. In actual transportation, driver operation, cargo loading and unloading collisions, or unintentional touches by other personnel may all lead to arbitrary changes to the temperature parameters on the control panel. Furthermore, existing vehicle-mounted refrigerators have shortcomings in terms of compatibility with trucks. Most refrigerators are simply placed inside the vehicle, a placement method that results in poor stability. During truck travel, due to bumps, turns, and other road conditions, the refrigerators are prone to displacement and shaking. On the one hand, this may damage the refrigerator itself, shortening its lifespan; on the other hand, it also poses a collision risk to other goods or equipment inside the vehicle, affecting transportation safety. Moreover, haphazardly placed refrigerators occupy a significant amount of interior space, reducing the space available for loading other goods, thus lowering overall transportation capacity and economic efficiency. Furthermore, the built-in condenser's heat dissipation performance is relatively weak, making it difficult to meet the demands of prolonged, high-intensity operation. To maintain the condenser's normal heat dissipation function, a cooling fan must be added for auxiliary cooling. The addition of a cooling fan not only increases production costs but also consumes additional electricity during long-term use, increasing operating costs. Moreover, the noise generated by the fan can cause some interference with the transportation environment. Summary of the Invention
[0004] The purpose of this invention is to provide a truck-compatible, multi-structure integrated, improved vehicle-mounted refrigerator to solve the problems mentioned in the background art.

The freezer door has a mounting groove, the inner wall of which is fitted with a silicone sealing ring. A control panel is located inside the mounting groove, and a display operation panel is located at the port of the mounting groove. The display operation panel is connected to the control panel.
[0006] As a preferred embodiment of the present invention, several fixing plates are welded to the back of the condenser, and the fixing plates are fixed to the back of the refrigerator body by several screws.
[0007] As a preferred embodiment of the present invention, a lock is provided on the refrigerator door, and a reinforcing iron latch is provided on one inner wall of the refrigerator body, the reinforcing iron latch corresponding to the position of the lock when the refrigerator door is closed.
[0008] As a preferred embodiment of the present invention, a pair of fixing frame strips are provided on the outer side of the refrigerator body. The fixing frame strips are fixedly sleeved on the outer wall of the refrigerator body. Screw holes are provided on both sides of the top of the two fixing frame strips. The two fixing frame strips are fixed to the bottom of the truck frame by a pair of bolts passing through the screw holes.
[0009] As a preferred embodiment of the present invention, a pair of latches are provided on the side of the refrigerator door away from the hinge, and the latches are fastened to the refrigerator body.
[0010] As a preferred embodiment of the present invention, a pull groove is provided on the side of the refrigerator door, and the pull groove is located between two latches.

[0012] As a preferred embodiment of the present invention, a pair of slide rails are provided on each of the inner walls on both sides of the insulation board, and the two fixing components are respectively located between the two pairs of slide rails; the fixing component includes a fixing shell disposed in the insulation board, a spring disposed in the fixing shell, and a pin disposed at the top of the spring; the partition is provided with slide grooves on both sides corresponding to the positions of the slide rails, and a positioning hole is provided in the middle of the slide groove corresponding to the position of the fixing component.
[0013] Compared with the prior art, the above-mentioned technical solution of the present invention has the following beneficial technical effects: 1. This invention integrates the control panel into the freezer door inside the refrigerator, requiring the door to be opened for access. This concealed design physically prevents unauthorized personnel from accidentally touching the control panel, ensuring that temperature parameters are consistently maintained within the customer-preset safe range. This effectively avoids problems such as spoilage of fresh produce and failure of pharmaceutical reagents due to temperature fluctuations, reducing cargo damage costs and compensation risks for logistics companies, and significantly improving the reliability of cold chain transportation services. Furthermore, the silicone sealing ring structure on the inner wall of the mounting slot prevents moisture from entering the mounting slot and blocks airflow between the control panel and the outside environment. Even in environments with large temperature differences, it prevents condensation from forming on the control panel surface, preventing condensation from seeping into the circuit and causing short circuits or malfunctions. This ensures stable operation of the control panel in humid and temperature-sensitive vehicle environments. 2. The condenser of this invention is mounted on the back of the refrigerator body with four fixed plates, which increases the contact area with the outside air, enabling more efficient heat dissipation and improving heat dissipation performance. This eliminates the need for a cooling fan, effectively reducing costs. This not only optimizes the operation of the refrigerator's refrigeration system but also saves on economic costs, improving the product's cost-effectiveness.
[0014] 3. The present invention uses two fixed frame strips on the outside of the refrigerator body to evenly distribute and bear the weight and pressure of the refrigerator body. It is tightly connected to the bottom of the truck frame by four bolts, so that the refrigerator is firmly fixed during transportation, which greatly avoids shaking or displacement. At the same time, this fixing method saves interior space, makes the interior layout more reasonable and orderly, frees up more space for transporting other items, and improves transportation efficiency and space utilization.
[0015] 4. This invention features a lock on the refrigerator door. A key inserted into the lock rotates it 90°, causing the lock cylinder to engage precisely with the reinforced iron latch, thus locking the refrigerator door. This design effectively prevents unauthorized opening, ensuring the safety of food and items inside the refrigerator and preventing theft or damage. Furthermore, the lock structure is relatively simple, making it easy to maintain and replace in case of malfunction during long-term use, reducing operating costs and maintenance difficulty, and extending the refrigerator's lifespan.
[0016] 5. This invention uses a magnetic block on the freezer door to temporarily suspend the freezer door, allowing users to flexibly adjust the internal space layout of the refrigerator according to their actual needs. The magnetic door design also greatly facilitates users in taking and putting in items. Users can easily open and close the door without complicated operations, especially when taking items with both hands, making it more convenient to use the refrigerator and improving the user experience and ease of operation.
[0017] 6. This invention facilitates compressor maintenance by providing a detachable baffle. Attached Figure Description

The fixing plates 6 are fixed to the back of the refrigerator body 1 by several screws 5. The front of the refrigerator body 1 is connected to the refrigerator door 4 by several hinges 3, which allows the refrigerator door 4 to open and close. A lock 40 is provided on the refrigerator door 4, and a reinforced iron lock 41 is provided on the inner wall of one side of the refrigerator body 1. When the refrigerator door 4 is in the closed state, the lock 40 and the reinforced iron lock 41 are precisely engaged to ensure that the refrigerator door 4 can be tightly closed, effectively maintaining the temperature environment inside the refrigerator. An insulation board 01 is integrally formed on the upper part of the inner wall of the refrigerator body 1. A partition 02 is provided inside the insulation board 01. Fixing components 03 are symmetrically arranged on the inner walls on both sides of the insulation board 01. The partition 02 divides the interior of the refrigerator body 1 into a freezer compartment 13 and a refrigerator compartment 130. The freezer compartment 13 is located at the top inside the refrigerator body 1. The insulation plate 01 has a movable groove 14. The freezer door 15 is rotatably mounted in the movable groove 14 through the rotating shafts 16 symmetrically arranged on both sides of the top, thereby realizing the opening and closing action of the freezer door 15 relative to the freezer compartment 13. A pair of magnets 17 are provided on the front of the freezer door 15. When the freezer door 15 is flipped up and opened and contacts the top inside the refrigerator body 1, the magnets 17 can be attracted and made easy for the user to take out the items in the freezer compartment 13. The freezer door 15 has a mounting groove 150, a silicone sealing ring 151 is provided on the inner wall of the mounting groove 150, a control panel 9 is provided inside the mounting groove 150, and a display operation panel 90 is provided on the port of the mounting groove 150, and the display operation panel 90 is connected to the control panel 9. On the outside of the refrigerator body 1, there is a pair of fixing frame strips 7, which are tightly fixed to the outer wall of the refrigerator body 1. Both sides of the top of the two fixing frame strips 7 are provided with screw holes 70. By passing a pair of bolts through the screw holes 70, the refrigerator body 1 can be firmly fixed to the bottom of the truck frame. A pair of latches 8 are provided on the side of the refrigerator door 4 away from the hinge 3. When the refrigerator door 4 is closed, the latches 8 can be firmly locked on the refrigerator body 1, further enhancing the stability of the refrigerator door 4 when closed. At the same time, a pull groove 42 is provided on the side of the refrigerator door 4 between the two latches 8. When the user needs to open the refrigerator door 4, he / she can easily complete the opening action by pulling the pull groove 42. In addition, the refrigerator compartment 130 is equipped with several detachable shelves 12. These shelves can rationally divide the internal space of the refrigerator, making it convenient for users to classify and store various items. A pair of slide rails 101 are provided on each of the inner walls of the two sides of the insulation board 01, and two fixing components 03 are located in the middle of the two pairs of slide rails 101 respectively.
