[0044] The technical solutions provided by the various embodiments of this application are described below with reference to the accompanying drawings.

[0045] See Figures 1 to 4This invention provides a vehicle refrigerator, including a body 1, a storage box 2 placed inside the body 1, a flip-up lid 3 mounted on the top of the body 1, and a door 4 located at the front end of the body 1. The body 1 contains a cooling chamber and a cooling component, which is existing technology and will not be described in detail here. The cooling chamber has openings at its upper and front ends. The storage box 2 is used to store items and is placed inside the cooling chamber. The door 4 and lid 3 correspondingly cover the two openings of the cooling chamber. A sliding frame 5 is installed on the door 4, and the sliding frame 5 is slidably installed inside the body 1. The storage box 2 is inserted into the sliding frame 5 from top to bottom. In use, the door 4 can be pulled out or the lid 3 can be flipped open. This structure features a dual opening mechanism of drawers and flip-tops, offering greater flexibility and allowing for unrestricted access to items, making it more convenient to use. When height is limited, the storage box 2 can be pulled out by sliding the door, or it can be taken out directly after being pulled out. When front space is limited, items can be accessed by flipping the lid 3, or the storage box 2 can be taken out directly, making it convenient to access items.

[0046] See Figures 5 to 11 The door body 4 is equipped with a handle 6 and a door lock structure that is driven and connected to the handle 6. The door lock structure is used to lock the housing 1 and the door body 4. The handle 6 is rotatably mounted on the door body 4. Rotating the handle 6 can unlock or lock the door lock structure. When the handle 6 is in a vertically retracted state (e.g. Figure 1 When the door lock mechanism is engaged, both the housing 1 and the door 4 are locked; when the handle 6 is in a downward or horizontal pulling position (e.g. Figure 5 When the door lock mechanism is unlocked, both the cabinet 1 and the door 4 are unlocked. At this time, the storage box 2 can be pulled out using the handle 6. When the handle 6 is in the upward-sloping position (e.g., Figure 11 When the door lock mechanism is engaged, both the refrigerator body 1 and the door 4 are locked. At this point, the entire vehicle refrigerator can be lifted using the handle 6. This structure cleverly integrates the handle and unlocking functions, allowing for unlocking while unfolding the handle, thus increasing ease of use.

[0047] In some embodiments, such as Figure 5 , Figure 9 and Figure 10As shown, the door lock structure includes multiple movable latches 801 that are driven and connected to the handle 6. The use of multiple movable latches 801 ensures stable and reliable locking. The movable latches 801 are elliptical and can be installed at the end of the door body 4 facing the housing 1. The housing 1 has slots 101 for the movable latches 801 to be inserted into. The positions of the slots 101 correspond to the positions of the movable latches 801. Upper locking pins 102 and lower locking pins 103 are respectively installed at the upper and lower ends of the slots 101. The upper locking pins 102 and lower locking pins 103 are arranged at intervals and have the same cylindrical structure. The movable latches 801 are arrow-shaped, and their two sides are respectively provided with a first locking groove 802 and a second locking groove 803 for engaging with the upper locking pins 102 and lower locking pins 103.

[0048] When handle 6 is in the retracted state, the movable latch 801 engages with the locking pin 102, locking the box 1 and the door 4. When handle 6 is in the pulled-out state, the movable latch 801 descends and disengages from the locking pin 102, unlocking the box 1 and the door 4. When handle 6 is in the lifted state, the movable latch 801 descends and engages with the lower locking pin 103, locking the box 1 and the door 4.

[0049] Existing door lock structures are unsuitable for outdoor use. When used outdoors, external force can easily cause the drawer latches to disengage or the drawer to fall out of the refrigerator. Furthermore, with existing drawer designs, lifting the refrigerator using the handle can easily pull the drawer out. In this embodiment, the aforementioned handle and door lock structure, employing multiple movable latches, securely locks the door, preventing it from falling out during use. When lifting the refrigerator using the handle, the handle drives the door lock structure to firmly lock the door, preventing it from falling out and ensuring reliable operation.

[0050] In some embodiments, such as Figures 6 to 8 As shown, the handle 6 is connected to the movable latch 801 via a drive structure, and the handle 6 can drive the movable latch 801 to descend via the drive structure. Receiving cavities 401 are respectively provided on both sides of the door body 4, and cover plates are installed on both sides of the door body 4 to cover the receiving cavities 401. Two sets of drive structures are installed in the corresponding receiving cavities 401; the use of two sets of drive structures ensures even locking force and a stable and reliable structure.

[0051] The drive structure includes a drive plate 7 rotatably installed in the receiving cavity 401 and a lifting lock plate 8 that can be lifted and lowered in the receiving cavity 401. The drive plate 7 is drivenly connected to the lifting lock plate 8 through a transmission component 9. Multiple movable lock tongues 801 are arranged at intervals along the vertical direction on the lifting lock plate 8. The movable lock tongues 801 extend to the outside of the door body 4. The door body 4 is provided with a straight through hole 402 for the movable lock tongues 801 to extend out.

[0052] The drive structure also includes a drive shaft 10 rotatably mounted inside the door body 4, two drive plates 7 respectively mounted at both ends of the drive shaft 10, and a U-shaped handle 6 mounted in the middle of the drive shaft 10. The front wall of the door body 4 has a handle groove 403 for accommodating the handle 6; in the retracted state, the handle 6 is placed within the handle groove 403. During operation, the handle 6 rotates, causing the drive shaft 10 to rotate, which in turn causes the drive plates 7 to rotate. The drive plates 7, through a transmission component 9, drive the lifting lock plate 8 to slide, which in turn causes the movable lock tongue 801 to slide.

[0053] In some embodiments, such as Figures 6 to 8 As shown, the transmission component 9 is a connecting rod, one end of which is hinged to the drive plate 7, and the other end is hinged to the lifting lock plate 8. There are two connecting rods, symmetrically arranged on both sides of the lifting lock plate 8. A spring 11 is installed between the lifting lock plate 8 and the door body 4, and the spring 11 always tends to make the lifting lock plate 8 move upward. In the retracted state, the force of the spring 11 causes the movable lock tongue 801 to engage with the locking pin 102. A torsion spring 12 is installed between the drive plate 7 and the door body 4, and the torsion spring 12 is used to reset the drive plate 7.

[0054] In some embodiments, such as Figures 6 to 8 As shown, the lifting lock plate 8 is provided with multiple guide grooves 804, and the door body 4 is provided with multiple guide posts 404 that are adapted to the guide grooves 804. Through the cooperation of the guide grooves 804 and the guide posts 404, the lifting lock plate 8 can slide only vertically, ensuring the feasibility of the structure. The lifting lock plate 8 is convex in shape, and there are three guide grooves 804 respectively arranged on the upper, middle and lower sides of the lifting lock plate 8. The guide posts 404 include a first guide post, a second guide post and a third guide post. A fixed post 405 is installed above the first guide post. A first pressure plate 13 is installed between the fixed post 405 and the first guide post. A second pressure plate 14 is installed between the second guide post and the third guide post. The first pressure plate 13 and the second pressure plate 14 are used to limit the lifting lock plate 8.

[0055] In some embodiments, such as Figure 5 As shown, a positioning post 406 is installed at the end of the door 4 facing the box 1, and a positioning groove 104 corresponding to the positioning post 406 is provided on the box 1.

[0056] In some embodiments, such as Figure 1 , Figure 2 and Figure 4As shown, a positioning frame 15 is inclinedly arranged on one side of the top of the cabinet 1. The upper end of the door 4 is inclined and fits against the lower end of the positioning frame 15. The lower end of the lid 3 is inclined and fits against the upper end of the positioning frame 15. In this embodiment, the positioning frame 15 is inclined, but it can also be non-inclined in actual design. The function of the positioning frame 15 is to support the entire frame of the refrigerator. The control and display parts of the refrigerator can also be installed on it. In addition, it can also work with the lid 3 to provide a sealing function. Positioning buckles 151 are symmetrically arranged on the upper surface of the positioning frame 15. One end of the lid 3 is hinged to the cabinet 1, and the other end of the lid 3 is hinged to a pressing plate 301. Elastic buckles 302 that can engage with the positioning buckles 151 are symmetrically arranged on the pressing plate 301. When the lid 3 is closed, the elastic buckles 302 can engage with the corresponding positioning buckles 151. When the lid 3 is opened, the pressing plate 301 is pressed, and the pressing plate 301 can drive the elastic buckles 302 to disengage from the positioning buckles 151.

[0057] In some embodiments, such as Figure 2 and Figure 3 As shown, horizontally extending slide rails 105 are symmetrically installed on the inner wall of the box 1, and the sliding frame 5 is slidably connected to the box 1 through the slide rails 105; hand slots 201 are symmetrically provided on both sides of the storage box 2, which makes it convenient for people to hold and lift the storage box 2 upwards.

[0058] The same or similar parts between the various embodiments in this specification can be referred to mutually. Each embodiment focuses on describing the differences from other embodiments.

[0059] The above description is merely a specific embodiment of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
