Description

Technical Field

[0001] This invention relates to the field of vehicle-mounted refrigerator technology, specifically a motorcycle-mounted refrigerator. Background Technology

[0002] A car refrigerator is a portable refrigeration device designed specifically for vehicles, which can refrigerate or keep food and drinks fresh while driving.

[0003] However, existing car refrigerators rely on external power. When there is no power outdoors, the built-in battery runs out and the refrigerator cannot operate. Although there are external solar charging panels, the device is inconvenient to connect and has poor overall integration. Secondly, most car refrigerators use simple door latches, which have no anti-theft function and the latching force is difficult to control precisely. In addition, the functions of existing car refrigerators are single and fixed, which cannot meet the diverse needs of users and is difficult to upgrade and iterate according to future needs. Moreover, the heat dissipation holes of the compressor compartment do not have waterproof and dustproof structures, which limits outdoor all-weather use. Most dustproof designs also lack comprehensive protection and self-maintainable filter structures, resulting in difficult cleaning and high maintenance costs. In addition, when installed on a motorcycle, the rope binding is inconvenient and easy to loosen and fall off. Finally, existing car refrigerators lack a complete air duct system, resulting in poor heat dissipation, low cooling efficiency and unstable temperature at high temperatures. Summary of the Invention

[0004] The purpose of this invention is to provide a motorcycle-mounted refrigerator to address the problems mentioned in the background art, such as the reliance on external power sources for motorcycle refrigerators, which become inoperable when the built-in battery is depleted due to the lack of outdoor power, the inconvenience of external solar charging panels, poor overall integration, the lack of anti-theft features in most motorcycle refrigerators, the difficulty in precisely controlling the locking force, the limited and fixed functionality of motorcycle refrigerators which fail to meet diverse user needs and are difficult to upgrade and iterate according to future requirements, the lack of waterproof and dustproof structures in the compressor compartment's heat dissipation vents limiting all-weather outdoor use, the lack of comprehensive protection and self-maintaining filtration structures in most dustproof designs leading to difficult cleaning and high maintenance costs, the inconvenience of rope binding when mounted on a motorcycle, the tendency to loosen and fall off, and the lack of a complete air duct system resulting in poor heat dissipation, low cooling efficiency at high temperatures, and unstable temperature.

The power interface is electrically connected to the charging input end of the energy storage battery built into the box to realize the transmission of electrical energy.

[0023] Compared with the prior art, the beneficial effects of the present invention are: the motorcycle on-board refrigerator: 1. Functional differentiation is achieved through different modes of the latch assembly. In the normal latching mode, the lock cylinder does not intervene, and the locking is achieved solely by the mechanical structure of the latch, reducing mechanical wear of the lock cylinder and extending its service life. In the safety locking mode, the locking end of the lock cylinder mechanically jams the lock body, causing the bolt to also jam. The latch structure can provide pre-tightening force to ensure the door is sealed. The lock body design can be built-in or external, which is both beautiful and practical, effectively solving the door safety and sealing problems of car refrigerators during movement and storage. 2. The mounting bracket on the rear seat of the anti-theft base assembly provides an installation position for the mounting base. The screws on both sides of the mounting base cooperate with the mounting bracket, and then the nuts are tightened to make the mounting base firmly installed on the mounting bracket on the rear seat. It can withstand various vibrations and bumps during the motorcycle's operation, effectively preventing the mounting base from loosening or shifting, thus ensuring the stability of the vehicle refrigerator. Secondly, the positioning block on the mounting base cooperates with the positioning groove on the bottom of the cabinet, so that the cabinet can be quickly positioned and installed on the mounting base. The locking component on one side of the cabinet can quickly lock and unlock the vehicle refrigerator and the mounting base. The operation is convenient and enhances the connection stability while effectively preventing the vehicle refrigerator from being stolen. 3. The air duct cooling component can achieve efficient heat dissipation. Fan 1 blows directly onto the condenser located directly above the air inlet, quickly carrying away the hot air along the air duct. At the same time, it also carries away the heat generated by the compressor module and the compressor body, preventing heat from accumulating inside the cabinet. Secondly, Fan 2 at the air outlet rotates to form airflow, accelerating the exhaust of heat from the air duct to the outside, further enhancing the heat dissipation effect. Overall, it prevents hot air from accumulating and improves cooling efficiency. 4. The filter assembly features a replaceable filter screen installed in the compressor compartment air duct. This effectively prevents rainwater, dust, and insects from entering the compressor compartment, ensuring a clean and dry operating environment for internal components. This reduces the failure rate caused by moisture or dust accumulation. The filter screen is designed to be removable with screws and a filter screen holder, allowing users to easily remove, clean, or replace the filter screen without the need for professional maintenance. This extends the equipment's lifespan and reduces maintenance costs. 5. The expansion platform component provides a mounting base for the folding support frame via the mounting bracket. The folding support frame is fixed to the mounting bracket with rivets, and then the mounting bracket with the folding support frame is firmly fixed to the perimeter of the cabinet with screws. The folding support frame can support the expansion table and realize the folding function, which greatly saves space. Secondly, the expansion table is fixed to the folding support frame with rivets, providing a wide surface for placing items and expanding the usable space. At the same time, the hooks on both sides of the triangular plate can be inserted into the fixing slots on the expansion table to form a complete expansion platform, further expanding the usable space. In addition, the lamp holder is installed on the expansion table with screws to provide lighting when used outdoors. The beverage placement hole on the top table can be used to store beverages and prevent them from spilling. Finally, the knob can rotate 360 ​​degrees. When the expansion table is folded, the knob first passes through the matching hole on the expansion table and then rotates downwards so that the protrusion on the knob faces down. The matching hole on the expansion table cannot be passed through the knob, which can fix the folded expansion table and prevent it from loosening and spreading out, effectively storing the expansion table and reducing the space occupied. 6. The solar panel in the charging component is integrated into the surface of the door, with a compact structure that can absorb sunlight from multiple directions, improve the efficiency of light energy collection, and realize the integration of sunlight collection, energy storage and power consumption. It does not require an external power source and can start and operate even in the absence of electricity. The built-in energy storage battery can convert solar energy into electrical energy for storage, realize continuous power supply day and night, ensure the stable operation of the refrigerator's refrigeration system, and turn each vehicle refrigerator into a mobile, self-sufficient micro solar power station.

[0034] Working principle: When using this motorcycle refrigerator, the latch assembly 4 has two modes: normal latching and safety locking. In normal latching, the door 2 and the cabinet 1 are latched together. The latch 45 rotates around the first pivot 47, and its hook part 48 engages with the latch tail hook 41. The compressed spring pushes the self-locking button 49 to reset, causing the latch cover 44 to rotate around the second pivot 46 to lock and provide pre-tightening force. When the door 2 needs to be opened, the pressing part 411 of the self-locking button 49 is pressed, which pushes the long rod part 410 to compress the spring, causing the latch cover 44 to rotate in the opposite direction. The hook part 48 of the latch 45 separates from the latch tail hook 41, thus unlocking. In safety locking, after the hook part 48 of the latch 45 engages with the latch tail hook 41, the lock cylinder 413 is rotated. Its locking end 414 restricts the self-locking button 49, preventing the latch cover 44 from rotating, thus achieving anti-theft locking.

[0035] When installing the vehicle refrigerator, first place the mounting base 81 on the rear seat of the vehicle, then pass the screws 83 on both sides through the mounting bracket 82 on the rear seat and tighten them with nuts 84. Then place the refrigerator body 1 on the mounting base 81. The positioning block 85 on the mounting base 81 cooperates with the positioning groove at the bottom of the refrigerator body 1, and the anti-theft locking is achieved by using the locking component 4 on one side of the refrigerator body 1.

[0036] When the vehicle refrigerator is working, the fan 53 at the air inlet 52 runs and blows directly onto the condenser 56 located directly above it, carrying away hot air and simultaneously carrying away the heat generated by the compressor module 57 and the compressor body 58. The fan 55 at the air outlet 54 rotates to accelerate the heat dissipation and improve the cooling effect. The filter screen seat 61 in the filter assembly 6 at the air outlet 54 is fixed to the outer wall of the box 1 by the screw 63. The filter screen 62 is detachably installed on the filter screen seat 61 and is embedded in the groove 66 on the inner side of the filter screen seat 61 with a tight fit at the edge. The porous grid structure 64 of the filter screen 62 covers the opening area of ​​the air duct 51, which can block rainwater, dust and insects from entering. It can be pulled out for cleaning or replacement during maintenance.

[0037] When outdoors, the user can remove the car refrigerator from the rear seat and assemble the extension platform component 7. First, remove the screws 73 around the top of the cabinet 1, install the mounting post 71, place the top table 72 and lock it with screws 73.

The hooks 711 on both sides of the corner plate 710 are aligned with the fixing grooves 712 on the extension table 78 and inserted for installation. Finally, the light holder 713 is installed and fixed with screws. Items can be placed on the extension platform. The beverage placement hole 714 on the top table 72 can be used to place beverages. When folding up, first remove the corner plate 710, press the bottom switch of the folding support frame 75 to fold the extension table 78, pass the knob 715 through the matching hole 718 on the extension table 78, and rotate the knob 715 downwards to fix the folded table with the protrusion facing down.

[0038] When the car refrigerator needs to be charged, the solar panel 31 can be installed on the door 2. The surface of the solar panel 31 is flush with the outer surface of the door 2. The output end of the solar panel 31 is electrically connected to the power interface 33 on the box 1 through the solar power connection line 32, which is laid along the outer wall of the box 1 and fixed by the cable clip 34. The power interface 33 is electrically connected to the charging input end of the built-in energy storage battery of the box 1.
