[0023] Example 1: Please refer to Figure 1-Figure 4 , Figure 6 , Figure 7 , Figure 9-11 and Fig.13 As shown, the present invention provides a technical solution: an outdoor refrigerator, comprising an outdoor refrigerator body 1, on which an auxiliary mechanism 2 is arranged; The auxiliary mechanism 2 includes a placement box 201, a power transistor 212, a temperature sensor 213, a generator 214 and two sprockets 215. A box cover 202 is installed on one side of the placement box 201, and two symmetrical stabilizing frames 203 are installed at the bottom of the placement box 201. A round tube 204 is fixedly passed through the other side of the placement box 201. A current sensor 205, a rectifier 206, a voltage sensor 207, a filter 208 and a microcontroller 209 are installed at the bottom of the inner wall of the placement box 201. A reinforcement frame 210 is fixed inside the placement box 201, and a plurality of reinforcement rods 211 are fixed inside the reinforcement frame 210. The interior of the placement box 201 is connected to the interior of the round tube 204. One of the sprockets 215 is installed at the rotor shaft end of the generator 214, and the two sprockets 215 are connected by chain transmission. The outdoor refrigerator body 1 includes a main shell 101, and an auxiliary shell 102 is arranged near the bottom of one side of the main shell 101. The box 201 is fixed on one side of the auxiliary shell 102, and the two stabilizing frames 203 are installed on one side of the auxiliary shell 102. The end of the round tube 204 away from the box cover 202 is movable through the outer wall of the auxiliary shell 102. The power transistor 212 is located in a groove on one side of the auxiliary shell 102. The temperature sensor 213 is installed on the auxiliary shell 102. A mounting plate 103 is provided at the bottom of the inner wall of the auxiliary shell 102. The generator 214 is installed on the upper side of the mounting plate 103. A wheel with an axle 105 is provided between the mounting plate 103 and the auxiliary shell 102. Another sprocket 215 is fixedly sleeved on the outer surface of the axle of the wheel with an axle 105. A battery 123 is placed in a groove on one side of the auxiliary shell 102. The detection end of the temperature sensor 213 is aligned with the surface of the battery 123. A mounting block 121 is fixed to the inner wall of the main shell 101. Two thermal sensors 122 are installed on the mounting block 121. A main controller 127 is installed in a groove on one side of the main shell 101.

[0024] In this embodiment, when the user needs to use the outdoor refrigerator, the battery 123 is used to power the main controller 127, and then the first temperature threshold (corresponding to the two thermal sensors 122), the second temperature threshold (corresponding to the temperature sensor 213), the voltage threshold (corresponding to the voltage sensor 207) and the current threshold (corresponding to the current sensor 205) are set. When the wheel of the axle wheel 105 starts to rotate, the axle of the axle wheel 105 will also rotate, and the rotating axle wheel 105 will drive the sprocket 215 connected thereto to rotate, and the rotating sprocket 215 will drive the rotor shaft end of the generator 214 to rotate under the cooperation of the chain and one of the sprockets 215, and the rotating rotor shaft end of the generator 214 will rotate in the generator. The motor 214 generates electric energy with the cooperation of the fixed stator winding (i.e., using the principle of electromagnetic induction), and the generated alternating current will be transmitted to the inside of the rectifier 206, and then the rectifier 206 will convert the transmitted alternating current into direct current, and output it to the filter 208, and then the filter 208 will directly convert the transmitted direct current into smooth direct current without ripples, and output it to the power transistor 212. At the same time, the current sensor 205 will also constantly detect the current size of the circuit, and transmit the current data detected each time to the microcontroller 209 in the form of an electrical signal, and then the microcontroller 209 will preliminarily process the received current data, and then transmit the processed current data to the main controller 12 7. When the main controller 127 receives the transmitted current data, the main controller 127 will directly compare the received current data with the current threshold value set in advance by the main controller 127. When the main controller 127 compares the received current data with the current threshold value set in advance by the main controller 127, the main controller 127 will adjust the current output from the power transistor 212 through the cooperation of the microcontroller 209 and the power transistor 212 until the current data received by the main controller 127 is lower than the current data set in advance by the main controller 127. Then, the current of the appropriate size will be transmitted to the battery 123 to charge the battery 123. At the same time, the voltage sensor 207 will also constantly detect the voltage of the battery 123. The voltage data detected each time is transmitted to the microcontroller 209 in the form of an electrical signal. The microcontroller 209 then performs preliminary processing on the received voltage data, and then transmits the processed voltage data to the main controller 127. When the main controller 127 receives the transmitted voltage data, the main controller 127 directly compares the received voltage data with the voltage threshold value set in advance by the main controller 127. When the main controller 127 compares the received voltage data with the voltage threshold value set in advance by the main controller 127, the main controller 127 will not send an instruction to the microcontroller 209 to turn off the power transistor 212. Otherwise, an instruction will be sent to the microcontroller 209 to turn off the power transistor 212.Stop charging the battery 123. Similarly, the temperature sensor 213 will always monitor the temperature of the battery 123 during charging, so as to know whether a fault occurs during the charging process of the battery 123, or to help the main controller 127 know whether to let the power transistor 212 reduce the current to avoid overheating of the battery 123.

An evaporator 116 is arranged between the outer walls of the storage shell 115, a drying filter 117 is installed on the lower side of the main shell 101, a condenser 118 and a compressor 119 are installed on the upper side of the mounting plate 103, an air inlet end of the compressor 119 is connected to an air outlet end of the evaporator 116 through a first conduit, an air outlet end of the compressor 119 is connected to an air inlet end of the condenser 118 through a second conduit, a liquid outlet end of the condenser 118 is connected to a liquid inlet end of the drying filter 117 through a third conduit, a capillary tube 120 is installed at the liquid outlet end of the drying filter 117, an outlet end of the capillary tube 120 is installed at the inlet end of the evaporator 116, a mounting block 121 is fixed to the inner wall of the main shell 101, and two mounting blocks 121 are installed on the mounting block 121 A thermal sensor 122, wherein the detection end of one thermal sensor 122 is aligned with the bottom of the first storage shell 114, and the detection end of the other thermal sensor 122 is aligned with the bottom of the second storage shell 115, a battery 123 is placed inside a groove on one side of the auxiliary shell 102, a shell cover 124 is installed at the notch of the groove on one side of the auxiliary shell 102, a charging module 125 is installed inside a through hole on one side of the auxiliary shell 102, an interface module 126 is installed on the box cover shell 108, a main controller 127 is installed inside a groove on one side of the main shell 101, rubber plugs 128 are provided inside the bottom circular hole of the main shell 101 and at the liquid outlet inlet of the second storage shell 115, and the discharge end of the second storage shell 115 movably passes through the bottom of the inner wall of the main shell 101.

[0026] In this embodiment, when the user needs to use the outdoor refrigerator, the user can release the clamping relationship between the box buckles on the first cover plate 109 and the second cover plate 110 and the box cover shell 108, and then rotate the first cover plate 109 and the second cover plate 110 in sequence, and then put the items that need to be stored at low temperatures into the first storage shell 114 and the second storage shell 115, and then rotate the first cover plate 109 and the second cover plate 110 back to their original positions and fix them with corresponding box buckles, and then use the battery 123 to power the main controller 127, and then set the first temperature threshold (corresponding to the two thermal sensors 122), and finally inject the refrigerant from the injection port of the compressor 119 through professional skills, and after completing the injection operation, inject the refrigerant into the injection port. Seal it, and when everything is ready, the user can use the main controller 127 to start the compressor 119, the condenser 118 and the two thermal sensors 122. At this time, the started compressor 119 will compress the injected low-temperature and low-pressure gaseous refrigerant into high-temperature and high-pressure gaseous refrigerant, and then transport it to the inside of the condenser 118 through the cooperation of the second conduit. Then the started condenser 118 will dissipate the heat in the high-temperature and high-pressure gaseous refrigerant flow flowing inside it to the inside of the space composed of the main shell 101 and the auxiliary shell 102, and then discharge it into the environment through the heat dissipation holes on the auxiliary shell 102. At the same time, the high-temperature and high-pressure gaseous refrigerant will gradually cool and liquefy into high-pressure liquid refrigerant, and then the high-pressure liquid refrigerant output from the inside of the condenser 118 will be discharged. The refrigerant will be transported to the interior of the filter drier 117 through the cooperation of the third conduit. When the high-pressure liquid refrigerant enters the interior of the filter drier 117, the moisture or impurities in the high-pressure liquid refrigerant can be filtered out with the cooperation of the filter drier 117. The processed high-pressure liquid refrigerant will then be transported to the interior of the capillary tube 120. When the high-pressure liquid refrigerant enters the interior of the capillary tube 120, the capillary tube 120 will convert the high-pressure liquid refrigerant flowing into it into a low-temperature and low-pressure gas-liquid mixture refrigerant. The low-temperature and low-pressure gas-liquid mixture refrigerant output from the capillary tube 120 will then enter the interior of the evaporator 116. Then, the low-temperature and low-pressure gas-liquid mixture refrigerant entering the evaporator 116 will reduce the pressure, and the refrigerant Rapidly vaporizes, resulting in the absorption of heat inside the first storage shell 114 and the second storage shell 115. When the heat inside the first storage shell 114 and the heat inside the second storage shell 115 are absorbed, the internal temperature of the first storage shell 114 and the internal temperature of the second storage shell 115 will drop. At this time, the items inside the first storage shell 114 and the second storage shell 115 will be preserved at low temperatures. At the same time, the low-temperature and low-pressure gas-liquid mixed refrigerant after absorbing heat will become a low-temperature and low-pressure gaseous refrigerant, and then be transported back to the compressor 119 through the cooperation of the first conduit for a new round of circulation. At the same time, the two thermal sensors 122 will also detect the outer shell temperatures of the first storage shell 114 and the second storage shell 115 at all times.And each detected data is transmitted to the main controller 127 in the form of an electrical signal. When the main controller 127 receives the temperature data transmitted by the two thermal sensors 122, the main controller 127 will compare the two received temperature data with the first temperature threshold value set in advance by the main controller 127. When the two temperature data received by the main controller 127 are higher than the first temperature threshold value set by the main controller 127, the main controller 127 will continue to keep the compressor 119, the two thermal sensors 122 and the condenser 118 started. Otherwise, the compressor 119 and the condenser 118 will be temporarily turned off. When moving the outdoor refrigerator, first extend the box pull rod 107, then tilt the entire outdoor refrigerator, and then drive the outdoor refrigerator to move through the cooperation of the box pull rod 107 and the axle wheel 105. When going to the place you want to go, when you need to charge your mobile phone or other electronic products, just plug one end of the data cable into the interface module 126 and the other end of the data cable into the mobile phone or other electronic products, and you can use the battery 123 to charge it. ,

[0027] The effect and working principle of the entire mechanism are as follows: when the user needs to use the outdoor refrigerator, the user can release the clamping relationship between the box buckles on the first cover plate 109 and the second cover plate 110 and the box cover shell 108, and then rotate the first cover plate 109 and the second cover plate 110 in sequence, and then put the items that need to be stored at low temperatures into the first storage shell 114 and the second storage shell 115, and then rotate the first cover plate 109 and the second cover plate 110 back to their original positions and fix them with corresponding box buckles, and then use the battery 123 to power the main controller 127, and then set the first temperature threshold (corresponding to the two thermal sensors 122), the second temperature threshold (corresponding to the temperature sensor 213), and the voltage threshold (corresponding to the voltage sensor 20 7) and current threshold (corresponding to current sensor 205), and finally, through professional skills, the refrigerant is injected from the injection port of the compressor 119, and after the injection operation is completed, the injection port is sealed. When everything is ready, the user can use the main controller 127 to start the compressor 119, the condenser 118 (the fan on the condenser 118) and the two thermal sensors 122. At this time, the started compressor 119 will compress the injected low-temperature and low-pressure gaseous refrigerant into high-temperature and high-pressure gaseous refrigerant, and then transport it to the inside of the condenser 118 through the cooperation of the second conduit. Then the started condenser 118 will dissipate the heat in the high-temperature and high-pressure gaseous refrigerant flow flowing inside it to the space composed of the main shell 101 and the auxiliary shell 102. The high-temperature and high-pressure gaseous refrigerant is then discharged into the environment through the heat dissipation holes on the auxiliary shell 102. At the same time, the high-temperature and high-pressure gaseous refrigerant is gradually cooled and liquefied into high-pressure liquid refrigerant. The high-pressure liquid refrigerant output from the inside of the condenser 118 is then transported to the inside of the filter drier 117 through the cooperation of the third conduit. When the high-pressure liquid refrigerant enters the inside of the filter drier 117, the moisture or impurities in the high-pressure liquid refrigerant can be filtered out with the cooperation of the filter drier 117. The processed high-pressure liquid refrigerant is then transported to the inside of the capillary tube 120. When the high-pressure liquid refrigerant enters the inside of the capillary tube 120, the capillary tube 120 converts the high-pressure liquid refrigerant flowing into it into a low-temperature and low-pressure gas-liquid mixture refrigerant. The low-temperature and low-pressure gas-liquid mixture refrigerant output by the capillary tube 120 will enter the interior of the evaporator 116. Then, the low-temperature and low-pressure gas-liquid mixture refrigerant entering the evaporator 116 will be rapidly vaporized due to the pressure reduction, thereby absorbing the heat inside the first storage shell 114 and the second storage shell 115. When the heat inside the first storage shell 114 and the heat inside the second storage shell 115 are absorbed, the temperature inside the first storage shell 114 and the temperature inside the second storage shell 115 will drop. At this time, the items inside the first storage shell 114 and the second storage shell 115 will be preserved at low temperatures. At the same time, the low-temperature and low-pressure gas-liquid mixture refrigerant after absorbing heat will become a low-temperature and low-pressure gaseous refrigerant, and then through the cooperation of the first conduit,The heat is then sent back to the compressor 119 for a new cycle. At the same time, the two thermal sensors 122 will also detect the outer shell temperatures of the first storage shell 114 and the second storage shell 115 at all times, and transmit the detected data to the main controller 127 in the form of electrical signals. When the main controller 127 receives the temperature data transmitted by the two thermal sensors 122, the main controller 127 will compare the two received temperature data with the first temperature threshold value set in advance by the main controller 127. When the two temperature data received by the main controller 127 are higher than the first temperature threshold value set by the main controller 127, the main controller 127 will continue to keep the compressor 119, the two thermal sensors 122 and the condenser 118 started. Otherwise, the compressor 119 and the condenser 118 will be temporarily turned off. When moving the outdoor refrigerator, first extend the box pull rod 107 (, Fig.11 ), then tilt the entire outdoor refrigerator (as shown Fig.11As shown), then through the cooperation of the box pull rod 107 and the axle wheel 105, the outdoor refrigerator can be driven to move. When you go to the place you want to go, when you need to charge your mobile phone or other electronic products, just plug one end of the data cable into the interface module 126, and plug the other end of the data cable into the mobile phone or other electronic products, and you can use the battery 123 to charge it. When the wheel of the axle wheel 105 starts to rotate, the axle of the axle wheel 105 will also rotate, and the rotating axle wheel 105 will drive the sprocket 215 connected to it to rotate, and the rotating sprocket 215 will drive the rotor shaft end of the generator 214 to rotate under the cooperation of the chain and one of the sprockets 215, and the rotating rotor shaft end of the generator 214 will rotate. The generator 214 generates electric energy with the cooperation of the fixed stator winding (i.e., using the principle of electromagnetic induction), and the generated alternating current will be transmitted to the inside of the rectifier 206. Then the rectifier 206 will convert the transmitted alternating current into direct current, and output it to the filter 208. After that, the filter 208 will directly convert the transmitted direct current into smooth direct current without ripple (the direct current obtained after rectification has fluctuations and ripples), and output it to the power transistor 212. At the same time, the current sensor 205 will also constantly detect the current size of the circuit, and transmit the current data detected each time to the microcontroller 209 in the form of an electrical signal. Then the microcontroller 209 will perform preliminary processing on the received current data. The processed current data is then transmitted to the main controller 127. When the main controller 127 receives the transmitted current data, the main controller 127 will directly compare the received current data with the current threshold value set in advance by the main controller 127. When the main controller 127 compares the received current data with the current threshold value set in advance by the main controller 127, the main controller 127 will adjust the current output from the power transistor 212 through the cooperation of the microcontroller 209 and the power transistor 212 until the current data received by the main controller 127 is lower than the current data set in advance by the main controller 127. Then, the current of the appropriate size will be transmitted to the battery 123 to charge the battery 123. At the same time, the voltage sensor 207 will also constantly detect the voltage of the battery 123, and transmit the voltage data detected each time to the microcontroller 209 in the form of an electrical signal. The microcontroller 209 will then perform preliminary processing on the received voltage data, and then transmit the processed voltage data to the main controller 127. When the main controller 127 receives the transmitted voltage data, the main controller 127 will directly compare the received voltage data with the voltage threshold value set in advance by the main controller 127. When the main controller 127 compares the received voltage data with the voltage threshold value set in advance by the main controller 127, the main controller 127 will not send instructions to the microcontroller 209, and the power transistor 212 will be turned off.Otherwise, the microcontroller 209 will be instructed to turn off the power transistor 212 and stop charging the battery 123. Similarly, the temperature sensor 213 will also monitor the temperature of the battery 123 during charging, so as to know whether a fault occurs during the charging process of the battery 123, or to help the main controller 127 know whether to let the power transistor 212 reduce the current to avoid overheating of the battery 123.
