DETAILED DESCRIPTION

[0040] The technical solutions in the embodiments of the present application will be described clearly and completely below. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work fall within the protection scope of the present application.

[0041] Please refer to Figures 1 to 9 In the embodiments of the present application, a mobile refrigerator with replaceable battery comprises a refrigerator box body 10, a storage cavity 20 and a function cavity 30 are arranged in the box body 10, the storage cavity 20 is used for storing articles to be preserved, a temperature adjusting unit 40 and a power supply assembly 50 are arranged in the function cavity 30, the power supply assembly 50 provides operating power for the temperature adjusting unit 40, and the temperature adjusting unit 40 performs temperature adjusting treatment on the storage cavity 20; the power supply assembly 50 is provided with a battery 51 and a battery compartment 60, the battery 51 is replaceably connected in the battery compartment 60, and the battery compartment 60 is movably connected in the function cavity 30.

[0042] Specifically, first, the movable refrigerator is usually used outdoors, and can also be placed in the vehicle for carrying, and at the same time, the power supply in the vehicle can be connected to enable the refrigerator to operate, and the corresponding refrigeration or heating treatment is carried out for the storage and protection of the items that need to be stored at low temperature or high temperature. In order to enable the movable refrigerator to continue to operate after leaving the vehicle, a battery 51 needs to be installed to continue to provide operating power for the refrigerator by using the electric energy in the battery 51. Due to the overall size of the movable refrigerator, the installed battery 51 cannot be too large, and the electric energy provided by the battery 51 cannot be too much, so that the movable refrigerator using a replaceable battery 51 for power supply is adopted. When the capacity of the battery 51 is insufficient, the battery 51 can be replaced to provide electric energy for the movable refrigerator again.

[0043] The conventional replacement method generally adopts plug-in electrical contact points arranged in the refrigerator, and the battery 51 can be inserted into the refrigerator to enable the power supply interface of the battery 51 to abut against the electrical contact points to form an electrical connection and thus supply power to the refrigerator.

[0044] Secondly, since the opening of the movable refrigerator is usually arranged at the top to facilitate the taking of the items, the top space is usually occupied by the opening. Therefore, the replacement opening of the battery 51 is usually arranged on the side of the refrigerator, and the battery 51 is pushed into the refrigerator through the opening to connect the electrical contact points with the power supply interface. However, since the user cannot observe the electrical contact points in the refrigerator when plugging in or out the battery 51, only blind insertion can be performed, which is easy to cause plugging errors, and even damage the electrical contact points, resulting in failure of the refrigerator. Therefore, the battery compartment 60 movably connected to the refrigerator is arranged, so that the battery compartment 60 can be moved out of the box body 10 of the refrigerator, and the user can observe the plug-in slot 61 and the electrical terminal 62 arranged in the battery compartment 60, so as to facilitate the user to quickly and correctly insert the replaceable battery 51 into the plug-in slot 61, so that the power supply terminal 53 of the battery 51 and the electrical terminal 62 abut against each other to form an electrical connection and thus supply power to the refrigerator.

[0045] As shown in Figures 5 to 7 Preferably, the battery compartment 60 is provided with a plug-in slot 61 connected in the battery compartment 60, the battery 51 is provided with a plug-in part 52, and the plug-in slot 61 and the plug-in part 52 are matched with each other to enable the battery 51 to be replaceably and plug-in connected in the battery compartment 60. The plug-in slot 61 is replaceably and fixedly connected in the battery compartment 60.

[0046] Specifically, by setting the replaceable plug-in slot 61 in the battery compartment 60, the existing battery 51 group in the prior art can be used for power supply, especially the tool kit battery 51 in the existing product can be used for power supply. Because the tool kit battery 51 is usually only needed when the corresponding tool is used, and when the corresponding tool is not used, the tool kit battery 51 is in an idle state, so the idle tool kit battery 51 can be reused to power the mobile refrigerator. Moreover, it can be understood that a plurality of plug-in slots 61 can also be provided in the battery compartment 60, and even a plurality of batteries 51 can be inserted at the same time, and different tool kit batteries 51 can also be matched, such as tool kit batteries 51 of different models or different brands.

[0047] In addition, the specific setting position of the plug-in slot 61 is not limited by the present application, and the plug-in slot 61 can be easily observed after the battery compartment 60 is opened, thereby facilitating the insertion and removal of the battery 51. For example, it can be set at the front of the battery compartment 60 near the opening handle 63, or it can be set at the rear of the battery compartment 60 away from the opening handle 63, or it can be set on the side of the battery compartment 60. Moreover, as shown in the third embodiment of the present application, the plug-in slot 61 can also be provided on the top cover support 65 of the battery compartment 60, and the plug-in slot 61 can also be well observed after the top cover support 65 is opened, thereby facilitating the correct insertion of the battery 51. It can be understood that the plug-in slot 61 is usually not set at the bottom of the battery compartment 60 because it is not convenient to observe the plug-in slot 61.

[0048] Secondly, the plug-in slot 61 can also be replaced, and can be replaced according to the different interfaces of the tool kit battery 51 owned, thereby reusing the idle tool kit battery 51 owned by the user, thereby saving resources, avoiding waste, and being more environmentally friendly. It can be understood that the battery 51 can also be provided with a plug-in part 52 and a power supply terminal 53, the plug-in part 52 is inserted into the plug-in slot 61 to form a plug-in type fixed connection, thereby stably fixing the battery 51 in the battery compartment 60. In addition, the plug-in slot 61 is preferably provided with a power terminal 62, when the battery 51 is inserted into the plug-in slot 61, the power supply terminal 53 and the power terminal 62 abut each other and form an electrical connection, thereby transmitting the electrical energy in the battery 51 to the mobile refrigerator for use.

[0049] As Figure 1 , Figure 8 and Figure 9As shown, preferably, the part structure of the battery compartment 60 can be removed from the cabinet 10, so that the plug-in slot 61 is exposed outside the cabinet 10, and the replaceable plug-in of the battery 51 is facilitated. The battery compartment 60 is replaceably connected in the function cavity 30, and the battery compartment 60 is provided with an opening handle 63 fixedly connected to the battery compartment 60 and used for opening the battery compartment 60 from the cabinet 10.

[0050] Specifically, the plug-in slot 61 exposed outside the cabinet 10 can be exposed outside the space where the cabinet 10 is located. The plug-in slot 61 is not blocked by the cabinet 10, so that the user can directly observe the position of the plug-in slot 61 when replacing the battery 51, so that blind insertion does not occur when plugging in the battery 51, and the correct plug-in can be achieved at one time, reducing the error probability and reducing the damage probability of the mating electrical terminal 62.

[0051] Secondly, the battery compartment 60 can be connected to the cabinet 10 of the refrigerator in various movable connection modes, as long as at least part of the structure of the battery compartment 60 can be removed from the cabinet 10, so that the plug-in slot 61 is moved out of the cabinet 10 by a certain distance, so that the user can smoothly observe the plug-in slot 61. In addition, the battery compartment 60 is preferably replaceable, and when the structure of the used battery 51 is inconsistent with the structure of the original battery compartment 60, the entire battery compartment 60 can be directly replaced. Or after long-term use, the battery compartment 60 is worn out, and the entire battery compartment 60 can be directly replaced, thereby prolonging the service life of the movable refrigerator.

[0052] As shown in Figure 3 and Figure 4 As shown, preferably, the power supply assembly 50 is provided with a telescopic elastic cable 71, one end of the elastic cable 71 is fixedly connected to the function cavity 30, the other end of the elastic cable 71 is fixedly connected to the battery compartment 60, and the elastic cable 71 is electrically connected to the power supply assembly 50 and the temperature adjusting unit 40 respectively, so as to provide the power of the battery 51 of the power supply assembly 50 to the temperature adjusting unit 40.

[0053] Specifically, in order to prevent the connected cable from being pulled off or limiting the removal of the battery compartment 60 when the battery compartment 60 is removed from the cabinet 10, the cable can be provided as an elastic cable 71, such as a spiral elastic cable 71 or other flexible cable, which can be stretched and transmit power to a certain extent.

[0054] As shown in Figure 1As shown, in the first embodiment of the present invention, preferably, the battery compartment 60 is configured to be movably connected to the functional cavity 30 in a parallel push-pull opening and closing manner. The battery compartment 60 can be pulled away from the side of the housing 10 by a certain distance, so that the insertion slot 61 inside the battery compartment 60 is exposed outside the housing 10, which facilitates the replaceable plug-in connection of the battery 51. After the connection is completed, the battery compartment 60 can be pushed back into the housing 10.

[0055] Specifically, the parallel sliding opening and closing method can be configured using the structure of existing sliding cabinets. The sliding cabinet is preferably located on the side of the refrigerator body 10, and its specific location can be adjusted according to the refrigerator structure. It can be located below or above the temperature control unit 40. The sliding cabinet can be movably connected to the side of the body 10 via a guide rail 72 or other sliding connection method. The battery compartment 60 can be pulled out a certain distance from the side of the body 10, exposing the insertion slot 61 outside the body 10, allowing the user to directly observe the insertion slot 61 and quickly and correctly insert the battery 51 into the insertion slot 61. Subsequently, the battery compartment 60 can be pushed back into the side of the body 10, restoring the entire body 10 to a single unit.

[0056] like Figure 8 As shown, in the second embodiment of the present invention, preferably, the battery compartment 60 is configured to be movably connected to the functional cavity 30 in a rotating side-opening manner. The opening handle 63 of the battery compartment 60 is rotated at a certain angle on the side of the housing 10 to open the battery compartment 60, so that the insertion slot 61 inside the battery compartment 60 is exposed outside the housing 10, which facilitates the replaceable plug-in connection of the battery 51. After the connection is completed, the battery compartment 60 can be rotated at a certain angle and inserted back into the housing 10.

[0057] Specifically, the opening and closing mode of the rotating side can be set by using the structure of the rotating cabinet body in the prior art. Preferably, the cabinet 10 can be provided with a rotating shaft 73, and the rotating cabinet body can be provided with a rotating hole (not shown in the figure) or a bearing (not shown in the figure), so that the rotating cabinet body can be rotated by a certain angle from the side of the cabinet 10 through the cooperation of the rotating shaft 73 and the rotating hole, so that the opening of the battery compartment 60 is moved out of the cabinet 10, and the user can directly observe the plug-in slot 61, so that the battery 51 can be quickly and correctly inserted into the plug-in slot 61. Subsequently, the battery compartment 60 can be reversely rotated by a certain angle and re-clamped into the cabinet 10, so that the entire cabinet 10 is re-formed as a whole. In addition, a limiting portion (not shown in the figure) can be provided on the battery compartment 60, and a limiting block (not shown in the figure) can be provided on the cabinet 10, so that the battery compartment 60 cannot be rotated after being rotated by a certain angle through the limiting cooperation of the limiting portion and the limiting block, thereby avoiding damage to the battery compartment 60 when the battery compartment 60 is rotated by too large an angle. The limiting portion and the limiting block can use the existing structure in the prior art, such as a clamping hole and a clamping block, and thus will not be described here.

[0058] As shown in FIG. 1, Figure 9 In the third embodiment of the present application, the battery compartment 60 is preferably movably connected in the opening and closing mode of the rotating flip cover in the functional cavity 30. The opening handle 63 of the battery compartment 60 is rotated by a certain angle on the top surface of the cabinet 10, so as to open the battery compartment 60 and expose the plug-in slot 61 in the battery compartment 60 outside the cabinet 10, thereby facilitating the replaceable plug-in connection of the battery 51. After the connection is completed, the battery compartment 60 can be re-rotated by a certain angle and clamped into the cabinet 10.

[0059] Specifically, the opening and closing mode of the rotating flip cover can be set by using the structure of the flip cover support 65 in the prior art, and the plug-in slot 61 can also be provided on the flip cover support 65. Preferably, the cabinet 10 can be provided with a rotating shaft 73, and the flip cover support 65 can be provided with a rotating hole (not shown in the figure) or a bearing (not shown in the figure), so that the flip cover support 65 can be rotated by a certain angle from the top surface of the cabinet 10 through the cooperation of the rotating shaft 73 and the rotating hole, so that the flip cover support 65 is moved out of the cabinet 10, and the user can directly observe the plug-in slot 61, so that the battery 51 can be quickly and correctly inserted into the plug-in slot 61. Subsequently, the flip cover support 65 can be reversely rotated by a certain angle and re-clamped into the cabinet 10, so that the entire cabinet 10 is re-formed as a whole.

[0060] As shown in FIG. 1, Figure 3 , Figure 5 and Figure 9As shown, preferably, the battery compartment 60 is provided with a locking portion 64, and the box 10 is provided with a locking piece (not shown in the figure), the locking portion 64 and the locking piece are matched with each other, so that the battery compartment 60 is stably locked and connected to the box 10.

[0061] Specifically, in order to further stabilize the battery compartment 60, the locking portion 64 and the locking piece can be provided, so that the battery compartment 60 is locked. In addition, the locking portion 64 can be a buckle portion, and the locking piece can be a locking piece, the buckle portion and the locking piece are matched with each other, so that the battery compartment 60 is fixedly connected to the box 10 by means of buckle connection.

[0062] As shown, Figure 2 Preferably, the temperature adjusting unit 40 is provided with a compressor 41, a condenser 42 and an evaporator 43, the compressor 41 and the condenser 42 are fixedly connected in the function cavity 30, and the evaporator 43 is arranged on the storage cavity 20.

[0063] Specifically, the temperature adjusting unit 40 can use the existing compressor 41 refrigeration technology, wherein the compressor 41 and the condenser 42 are arranged in the function cavity 30, for providing low-temperature cold air or high-temperature gas to the evaporator 43; the evaporator 43 can be arranged in the storage cavity 20, and preferably arranged around the outer wall of the storage cavity 20, so as to refrigerate or heat the articles in the storage cavity 20.

[0064] In addition, the temperature adjusting unit 40 can also use semiconductor refrigeration technology, which includes a semiconductor refrigeration module (not shown in the figure), a heat conduction module (not shown in the figure) and a temperature conduction fan (not shown in the figure), the semiconductor refrigeration module is composed of a plurality of semiconductor refrigeration pieces (not shown in the figure), one end of the semiconductor refrigeration module is fixedly connected to the storage cavity 20, the other end of the semiconductor refrigeration module is fixedly connected to the heat conduction module, the heat conduction module is located in the function cavity 30, and the temperature conduction fan is fixedly connected to the heat conduction module.

[0065] Specifically, the semiconductor refrigeration module can be combined by a plurality of semiconductor refrigeration pieces as needed, and fixedly connected together through the heat conduction module, and the heat conduction module can be temperature-adjusted by the temperature conduction fan. Moreover, it is determined by the characteristics of the semiconductor refrigeration technology itself that it can realize the conversion of refrigeration or heating by reversing the current.

[0066] As shown, Figure 1 and Figure 8As shown, preferably, the box body 10 is provided with a power interface 11, which is used to access external power, so as to provide power for the temperature adjusting unit 40 and the power supply assembly 50; and the functional cavity 30 is provided with a control management chip 31, which is used to manage the operation process of the temperature adjusting unit 40 and the charging and discharging process of the power supply assembly 50.

[0067] Specifically, in order to facilitate the use of the movable refrigerator, the power interface 11 can also be provided, so that when the external power is conveniently accessed, the external power can be accessed through the power interface 11 to drive the temperature adjusting unit 40 to operate, and the battery 51 inserted in the battery compartment 60 can also be charged at the same time. It can be understood that the control management chip 31 is internally provided with an existing program in the prior art, so as to perform corresponding program management on the temperature adjusting unit 40 and the power supply assembly 50. In addition, preferably, a control panel 32 can also be provided on the shell of the functional cavity 30, which is used to adjust the program inside the control management chip 31 to perform a preset function or display a preset parameter.

[0068] As shown in the Figure 5 Preferably, the battery compartment 60 is provided with a physical identification switch 66, which is electrically connected with the control management chip 31. When the battery 51 is replaceably connected in the battery compartment 60, it abuts against and triggers the physical identification switch 66, so that the physical identification switch 66 sends a preset electrical signal to the control management chip 31.

[0069] Specifically, the preset electrical signal can be a voltage parameter commonly used in tool battery packs, such as 18V or 26V, so that the control management chip 31 can replace the battery management program according to the received electrical signal, such as 18V battery to enable the corresponding 18V battery charging and discharging management program, and 26V battery to enable the corresponding 26V battery charging and discharging management program. So as to avoid the identification error of the battery charging and discharging management program, causing the battery to be completely discharged and damaging the used tool battery pack.

[0070] In addition, the box body 10 of the movable refrigerator can also be provided with a moving wheel 12, a moving handle 13 and a moving pull rod 14, so as to facilitate the movement of the box body 10. The storage cavity 20 can also be provided with a storage cover 21, which is preferably covered on the opening of the storage cavity 20, so as to form a heat preservation effect on the storage cavity 20.

[0071] In use, first, the battery compartment 60 is moved out of the refrigerator body 10, so that the insertion slot 61 is observed, and then the replaceable battery 51 or the tool kit battery 51 is inserted along the insertion slot 61, so that the insertion piece 52 of the battery 51 and the insertion slot 61 are matched with each other, thereby fixing the battery 51, and the power supply terminal 53 on the battery 51 and the power connection terminal 62 on the insertion slot 61 abut with each other, forming an electrical connection. Then, the battery compartment 60 is pushed into the body 10 again. Then, the refrigerator is turned on through the control panel 32, so that the temperature adjusting unit 40 starts to operate, and the storage cavity 20 is temperature-adjusted.
