DETAILED DESCRIPTION

[0021] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0022] Reference Figure 1-4 This is an embodiment of the utility model, which discloses a portable multifunctional car refrigerator. Specifically, the car refrigerator includes an outer shell 1 and an inner tank 2 placed in the outer shell 1. The inner tank 2 is separated into a refrigeration chamber 21 and a fresh-keeping chamber 22 by a partition 3. It should be noted that in this embodiment, there is an insulation layer between the outer shell 1 and the inner tank 2, so that the freezing and refrigeration time can be kept longer. The insulation layer can be made of insulation cotton. The partition 3 is conducive to separating refrigeration and fresh-keeping, which is convenient for meeting a variety of different needs. In addition, the refrigeration volume and storage space can be adaptively selected according to technicians in the field. In this embodiment, the refrigerated volume can store 8 cans of canned beverages, and a refrigeration device 4 is provided between the inner liner 2 and the outer shell 1. Preferably, in this embodiment, the refrigeration device adopts a semiconductor refrigeration method, the principle of which is the refrigeration principle of an electronic chip, using a PN junction composed of special semiconductor materials to form a thermocouple pair to produce a Peltier effect, and a fan is configured for heat dissipation. It provides different temperatures for the refrigeration chamber 21 and the fresh-keeping chamber 22 to achieve cooling and preservation effects. Since both are mature refrigeration methods and are used in existing car refrigerators, they are not repeated here.

[0023] A circuit board 5 and a winding mechanism 6 are provided on the inner side of the housing 1 , and a wire 7 is wound around the outer side of the winding mechanism 6 . One end of the wire 7 is electrically connected to the circuit board 5 , and the other end passes through and extends to the outside of the housing 1 .

[0024] In some embodiments, the winding mechanism 6 in the present invention includes a fixed plate 61 arranged inside the housing 1, and a wire drum 62 is connected to the upper part of the fixed plate 61 through a torsion spring. The setting of the torsion spring can realize automatic resetting of the wire drum 62 after rotation, and the wire 7 is wound on the outside of the wire drum 62. Of course, considering the convenience of the wire 7 when rotating and paying out the wire, the present invention can also add an electric slip ring design inside the wire drum 62 to ensure the convenience of winding the wire drum 62, wherein the fixed plate 61 is also provided with a limiting component for limiting the rotation of the wire drum 62.

[0025] Based on the above embodiment, the limiting assembly in the present invention includes a ratchet 63 fixed to the outside of the wire drum 62, and a pawl 64 is rotatably connected to the end face of the fixed plate 61, and the pawl 64 cooperates with the ratchet 63, wherein a spring 65 is arranged between the fixed plate 61 and the pawl 64.

[0026] That is to say, in this embodiment, the ratchet 63 and the pawl 64 cooperate to prevent the reel 62 from reversing when the wire is released. In this way, the length of the wire 7 pulled out can be limited, so that the wire 7 can adapt to the power supply requirements of different distances, and has stronger applicability, meeting the power supply requirements at a long distance from the power source. At the same time, it can be stored in the reel 62 to save space.

[0027] The push rod 67 is located on the inner side of the housing 1 and is engaged with one side of the pawl 64. It should be noted that the push rod 67 described in this embodiment is set as an L-shaped rod, one end of which is in contact with the push block 66 and the other end is in contact with the outer side of the pawl 64. The purpose of this design is that when the power is turned on, the push rod 67 can be driven to contact the pawl 64 for movement. When the pawl 64 is separated from the ratchet, the wire drum 62 can quickly pull the wire 7 back to its original position under the drive of the torsion spring, thereby improving the convenience of operation.

[0028] Furthermore, the embodiment of the present invention further includes a wire fixing structure 8 , which is used to limit the end of the wire 7 .

[0029] In a preferred embodiment, the wire fixing structure 8 in the present invention includes two L-shaped frames 81 fixed on the end surface of the housing 1, and the two L-shaped frames 81 are arranged opposite to each other, wherein a limiting portion 82 is provided on the front side of the L-shaped frame 81, and a plug 71 is provided at the end of the wire 7, and the plug 71 is inserted into the two L-shaped frames 81.

[0030] Preferably, the plug 71 in this embodiment is configured as a USB connector, which can be directly connected to the power supply interface in the vehicle. Through the design of two L-shaped frames 81, a space for placing the plug 71 is formed. At the same time, the limiting portion 82 can prevent the plug 71 from slipping outward. When in use, the plug 71 can be pulled out upward, and at this time, the wire 7 can be further pulled outward.

[0031] It should be noted that in this embodiment, the top of the shell 1 is also hinged with a box cover 9, and the free end of the box cover 9 is connected to the shell 1 through a snap-fit ​​structure. The snap-fit ​​structure is a conventional technical means for those skilled in the art and will not be described in detail here. The snap-fit ​​mechanism is used to fix the box cover 9 to the shell 1 to improve the stability of the fixation of the box cover 9.

[0032] In summary, the refrigerator compartment 21 and the fresh-keeping compartment 22 designed in the present invention are used to meet the usage needs of different users to improve the overall functionality. Secondly, the winding mechanism 6 is used to wind the wire 7, so that the vehicle-mounted refrigerator can be connected to the power supply within a certain distance when in use, and can adapt to the power supply requirements of different distances. It has stronger applicability and meets the power supply requirements when it is long distance from the power source. At the same time, it is stored in the wire reel 62 to save space, thereby further improving its multi-functional usage needs and portable mobility. The overall structural design is simple and reasonable, and optimizes the applicability of existing vehicle-mounted refrigerators.

[0033] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
