Description

Technical Field

[0001] This invention relates to the field of vehicle refrigerator technology, and more particularly to a vehicle refrigerator and vehicle. Background Technology

[0002] This section provides only background information relevant to this disclosure and is not necessarily prior art.

[0003] A car refrigerator is a refrigerated cabinet that can be carried in a car. Car refrigerators generally come in drawer-type, flip-top, and side-opening types, with side-opening car refrigerators gaining popularity due to their ease of use and adaptability to user habits. To ensure effective refrigeration, a car refrigerator must have excellent sealing and insulation properties.

[0004] Current side-by-side car refrigerators typically have a sealing cover at the bottom of the side-by-side door structure. When users want to take out items, they need to open the side-by-side door and then open the sealing cover, which is quite cumbersome. Alternatively, a sealing strip can be installed on the door, but this method cannot guarantee sufficient sealing, resulting in cold air loss, affecting the refrigerator's cooling efficiency, and increasing energy consumption. Summary of the Invention

[0005] The purpose of this invention is to at least solve the problems of poor sealing performance and inconvenience in use of side-by-side car refrigerators. This purpose is achieved through the following technical solution:

The sealing assembly includes a first seal on a first door and a second seal on a second door. The transmission mechanism is connected to the first and second doors and can drive the doors to open or close synchronously. When the transmission mechanism drives the first and second doors to close synchronously, the first and second doors press against the first and second seals, forming an interference fit between them. This ensures effective sealing of the first and second seals, sealing the gap between the first and second doors, thereby improving the sealing performance of the doors, ensuring the cooling effect of the vehicle refrigerator, and reducing energy consumption.

[0058] Exemplary embodiments of the present disclosure will now be described in more detail with reference to the accompanying drawings. While exemplary embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure may be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the disclosure to those skilled in the art.

[0059] It should be understood that the terminology used herein is for the purpose of describing particular exemplary embodiments only and is not intended to be limiting. Unless the context clearly indicates otherwise, the singular forms “a,” “an,” and “described” as used herein may also include the plural forms. The terms “comprising,” “including,” “containing,” and “having” are inclusive and therefore indicate the presence of the stated features, steps, operations, elements, and / or components, but do not exclude the presence or addition of one or more other features, steps, operations, elements, components, and / or combinations thereof. The method steps, processes, and operations described herein are not construed as requiring them to be performed in a particular order described or illustrated unless the order of performance is explicitly indicated. It should also be understood that additional or alternative steps may be used.

[0060] Although terms such as first, second, third, etc., may be used in this document to describe multiple elements, components, regions, layers, and / or segments, these elements, components, regions, layers, and / or segments should not be limited by these terms. These terms may be used only to distinguish one element, component, region, layer, or segment from another. Unless the context clearly indicates otherwise, terms such as "first," "second," and other numerical terms used herein do not imply order or sequence. Therefore, the first element, component, region, layer, or segment discussed below may be referred to as the second element, component, region, layer, or segment without departing from the teachings of the exemplary embodiments.

[0061] For ease of description, spatial relative terms may be used in the text to describe the relationship of one element or feature relative to another element or feature, as shown in the figure. These relative terms include, for example, "inside," "outside," "middle," "outer," "below," "below," "above," "over," etc. Such spatial relative terms are intended to include different orientations of the device in use or operation, other than those depicted in the figure. For example, if the device in the figure is flipped, an element described as "below other elements or features" or "below other elements or features" would subsequently be oriented "above other elements or features" or "above other elements or features." Therefore, the example term "below" can include both upper and lower orientations.

[0062] A car refrigerator is a refrigerated cabinet that can be carried in a car. Currently, car refrigerators on the market mainly come in several door opening types, including front-opening, drawer-type, flip-top, and side-by-side opening. Among these, side-by-side opening car refrigerators are increasingly favored due to their ease of use and adaptability to user habits. To ensure the refrigeration effect of a car refrigerator, it must have good sealing and insulation performance. The gap between the two doors of a side-by-side opening car refrigerator is prone to cold leakage; therefore, improving the sealing performance of side-by-side opening car refrigerators is a pressing issue that needs to be addressed.

[0063] In related technologies, side-by-side car refrigerators typically have a sealing cover installed below the side-by-side door structure. When users want to take out items, they need to open the side-by-side door and then open the sealing cover, which is quite cumbersome. Alternatively, a sealing strip can be installed on the door, but this method cannot guarantee sufficient sealing, resulting in cold air loss, affecting the refrigerator's cooling efficiency, and increasing energy consumption.

[0064] In view of this, this embodiment provides a vehicle refrigerator 100, which aims to drive the first door 21 and the second door 22 to open or close synchronously by setting a transmission mechanism. At the same time, a first sealing element 31 and a second sealing element 32 are respectively set on the first door 21 and the second door 22. When the first door 21 and the second door 22 close synchronously, the first sealing element 31 and the second sealing element 32 are squeezed, so that the first sealing element 31 and the second sealing element 32 form an interference fit, thereby improving the sealing performance between the two doors of the double door body 2 and solving the above-mentioned technical problems.

[0065] like Figures 1 to 12As shown, according to an embodiment of the present invention, a vehicle refrigerator 100 is provided. The vehicle refrigerator 100 includes a cabinet 1, a double-door body 2, a sealing assembly, and a transmission mechanism. The cabinet 1 has a storage chamber with an opening on one side. The double-door body is located at the opening and is used to open or close the cabinet 1. The double-door body 2 includes a first door 21 and a second door 22. The first door 21 and the second door 22 are respectively openable and closable at the opening of the cabinet 1. The opening and closing method can be that the first door 21... The first door 21 and the second door 22 are hinged to the opening of the box 1. That is, the left side of the upper end of the box 1 is hinged to the first door 21, and the right side of the upper end of the box 1 is hinged to the second door 22. Alternatively, the opening and closing method can also be a sliding opening and closing, that is, the first door 21 and the second door 22 can slide relative to the box 1. When the first door 21 and the second door 22 move in a relatively far away direction, the box 1 is opened. When the first door 21 and the second door 22 move in a relatively close direction, the box 1 is closed.

[0066] The sealing assembly includes a first seal 31 and a second seal 32. The first seal 31 is disposed on the side of the first door 21 facing the second door 22 and is connected to the first door 21. The second seal 32 is disposed on the side of the second door 22 facing the first door 21 and is connected to the second door 22. When the first door 21 and the second door 22 are closed, the first seal 31 and the second seal 32 are in an interference fit.

[0067] The transmission mechanism is connected to the first door body 21 and the second door body 22. The transmission mechanism drives the first door body 21 and the second door body 22 to open or close synchronously. When the first door body 21 and the second door body 22 are closed, an interference fit is formed between the first sealing element 31 and the second sealing element 32. Driven by the transmission mechanism, the first door body 21 and the second door body 22 open or close synchronously. When the transmission mechanism drives the first door body 21 and the second door body 22 to close, the movable ends of the first door body 21 and the second door body 22 move synchronously towards the opening. When the first sealing element 31 and the second sealing element 32 come into contact, the first door body 21 and the second door body 22 continue to move in the closing direction, causing the first sealing element 31 and the second sealing element 32 to be compressed and deformed. This creates an interference fit between the first sealing element 31 and the second sealing element 32, ensuring effective sealing and improving the sealing performance between the first door body 21 and the second door body 22.

[0068] The vehicle refrigerator 100 of the present invention is provided with a sealing assembly and a transmission mechanism. The sealing assembly includes a first sealing element 31 disposed on a first door 21 and a second sealing element 32 disposed on a second door 22. The transmission mechanism is connected to the first door 21 and the second door 22 and can drive the doors to open or close synchronously. When the transmission mechanism drives the first door 21 and the second door 22 to close synchronously, the first door 21 and the second door 22 squeeze the first sealing element 31 and the second sealing element 32, so that the first sealing element 31 and the second sealing element 32 form an interference fit, ensuring the effective sealing of the first sealing element 31 and the second sealing element 32, thereby sealing the gap between the first door 21 and the second door 22, thereby improving the sealing performance of the double-leaf door 2, ensuring the cooling effect of the vehicle refrigerator 100, and reducing energy consumption.

[0069] In some embodiments of the present invention, the first sealing member 31 includes a first mounting portion 311 and a first sealing portion 312 connected together. A first mounting groove 211 is provided on the side of the first door body 21 facing the second door body 22, and the first mounting portion 311 is installed in the first mounting groove 211. The first sealing portion 312 is provided on the side of the first mounting portion 311 facing the second door body 22 and extends along the length direction of the first door body 21. The second sealing member 32 includes a second mounting portion 321 and a second sealing portion 322 connected together. A second mounting groove 221 is provided on the side of the second door body 22 facing the first door body 21, and the second mounting portion 321 is installed in the second mounting groove 221. The second sealing portion 322 is provided on the side of the second mounting portion 321 facing the first door body 21 and extends along the length direction of the second door body 22. When the first door body 21 and the second door body 22 are closed simultaneously, an interference fit is formed between the first sealing portion 312 and the second sealing portion 322.

[0070] Specifically, both the first sealing element 31 and the second sealing element 32 are sealing strips made of silicone or rubber, etc. The first sealing strip includes a first mounting portion 311 and a first sealing portion 312, which are integrally formed. The cross-sectional shape of the first sealing strip is T-shaped. A first mounting groove 211 is located on the side of the first door body 21 facing the second door body 22 and extends along the length of the first door body 21. The shape of the first mounting groove 211 matches the shape of the first mounting portion 311. The first mounting portion 311 is installed within the first mounting groove 211. The first mounting portion 311 is pressurized and pressurized against the first mounting groove 211, thus ensuring the first... The sealing strip is firmly fixed to the first door 21. Similarly, the second sealing strip includes a second mounting portion 321 and a second sealing portion 322, which are integrally formed. The cross-sectional shape of the second sealing strip is T-shaped. A second mounting groove 221 is provided on the side of the second door 22 facing the first door 21 and extends along the length of the second door 22. The shape of the second mounting groove 221 matches the shape of the second mounting portion 321. The second mounting portion 321 is installed in the second mounting groove 221 and is pressurized to form an interference fit with the second mounting groove 221, thus firmly fixing the second sealing strip to the second door 22. When the transmission mechanism drives the first door 21 and the second door 22 to close, the first door 21 and the second door 22 press the first sealing portion 312 and the second sealing portion 322, forming an interference fit between the first sealing portion 312 and the second sealing portion 322, ensuring an effective seal between the first door 21 and the second door 22, and improving the sealing performance of the vehicle refrigerator 100.

[0071] It is understandable that the cross-sectional shape of the first seal 31 and the second seal 32 can also be I-shaped or other shapes, and correspondingly, the shapes of the first mounting groove 211 and the second mounting groove 221 are adapted accordingly. In addition, the first seal 31 and the second seal 32 can also be connected to the double door body 2 by means of bonding, bolting or other methods.

[0072] In some embodiments of the present invention, such as Figures 7 to 12 As shown, the transmission mechanism includes a first transmission assembly 41 and a second transmission assembly 42. The first transmission assembly 41 includes a first connecting shaft 411, a first gear 412, and a first half gear 413. The first connecting shaft 411 is connected to the first door body 21. The first half gear 413 is sleeved on the first connecting shaft 411, and the first gear 412 meshes with the first half gear 413. The second transmission assembly 42 includes a second connecting shaft 421, a second gear 422, and a second half gear 423. The second connecting shaft 421 is connected to the second door body 22. The second half gear 423 is sleeved on the second connecting shaft 421, and the second gear 422 meshes with the second half gear 423 and the first gear 412, respectively.

[0073] Specifically, the first door 21 is hinged to the left side of the upper end of the housing 1 via the first connecting shaft 411, and the second door 22 is hinged to the right side of the upper end of the housing 1 via the second connecting shaft 421. The first half gear 413 and the second half gear 423 are symmetrically arranged. The first half gear 413 is sleeved on the first connecting shaft 411, and the second half gear 423 is sleeved on the second connecting shaft 421. The first gear 412 and the second gear 422 are symmetrically arranged. The first gear 412 is located to the right of the first half gear 413 and meshes with the first half gear 413. The second gear 422 is located between the first gear 412 and the second half gear 423 and meshes with both the second half gear 423 and the first gear 412.

[0074] By setting the first half gear 413 and the second half gear 423, the opening stroke of the first door 21 and the second door 22 can be satisfied, while making the structural arrangement of the components inside the cabinet 1 more compact, reducing the volume of the cabinet 1, and saving the space occupied by the vehicle refrigerator 100.

[0075] When the user manually opens the box 1, an upward force can be applied to the first door 21, the second door 22, or both doors. Here, we will use the example of applying an upward force to the first door 21. The first door 21 moves upward, causing the first connecting shaft 411 to rotate counterclockwise synchronously. This causes the first half gear 413 connected to the first connecting shaft 411 to rotate counterclockwise. The first half gear 413 then causes the first gear 412 meshing with it to rotate clockwise. The first gear 412 then causes the second gear 422 meshing with it to rotate counterclockwise. The second gear 422 then causes the second half gear 423 meshing with it to rotate clockwise. The second half gear 423 then causes the second connecting shaft 421 to rotate clockwise, which in turn causes the second door 22 connected to the second connecting shaft 421 to rotate clockwise synchronously, thus achieving the synchronous opening of the second door 22 and the first door 21.

[0076] When the user manually closes the enclosure 1, the first door 21 moves downward, causing the first connecting shaft 411 to rotate clockwise synchronously. This causes the first half gear 413 connected to the first connecting shaft 411 to rotate clockwise. The first half gear 413 then drives the first gear 412 meshing with it to rotate counterclockwise. The first gear 412 then drives the second gear 422 meshing with it to rotate clockwise. The second gear 422 then drives the second half gear 423 meshing with it to rotate counterclockwise. The second half gear 423 then drives the second connecting shaft 421 to rotate counterclockwise, which in turn drives the second door 22 connected to the second connecting shaft 421 to rotate counterclockwise synchronously, thus achieving the synchronous closing of the second door 22 and the first door 21.

[0077] In some embodiments of the present invention, the vehicle refrigerator 100 further includes a limiting mechanism; the limiting mechanism includes a first limiting member 61 disposed on the cabinet 1, the first limiting member 61 being used to limit the flip angle of the first door 21 relative to the cabinet 1; and / or, the limiting mechanism includes a second limiting member 62 disposed on the cabinet 1, the second limiting member 62 being used to limit the flip angle of the first door 21 relative to the cabinet 1.

[0078] It is understood that since the first door 21 and the second door 22 can be opened or closed synchronously by the drive of the transmission mechanism, a first limiting member 61, a second limiting member 62, or both can be provided. In this embodiment, a first limiting member 61 and a second limiting member 62 are included. The first limiting member 61 is used to limit the rotation angle of the first door 21 relative to the housing 1, and the second limiting member 62 is used to limit the rotation angle of the second door 22 relative to the housing 1, so that when the first door 21 and the second door 22 reach their maximum rotation angle, they will not continue to rotate, effectively improving the stability and reliability of the double doors 2 during their operation. The minimum rotation angle is 0°, that is, when the double doors 2 are closed, and the maximum rotation angle is 100°, that is, when the double doors 2 are fully open.

[0079] In some embodiments of the present invention, the first limiting member 61 includes a first limiting block, and the first half gear 413 includes a circumferentially extending first gear portion 4131 and a first gearless portion 4132. The first limiting block is configured to abut against the first gear portion 4131 to limit the first door body 21 when the first half gear 413 rotates. The second limiting member 62 includes a second limiting block, and the second half gear 423 includes a circumferentially extending second gear portion 4231 and a second gearless portion 4232. The second limiting block is configured to abut against the second gear portion 4231 to limit the second door body 22 when the second half gear 423 rotates.

[0080] Specifically, the cross-sectional shape of the first limiting block and the second limiting block is arc-shaped. The first limiting block extends vertically and is disposed on the left side wall of the housing 1, and the center of the first limiting block is embedded in the left side wall of the housing 1. The upper and lower ends of the first limiting block protrude from the side wall of the housing 1, respectively, and are the first limiting end face and the second limiting end face. The first half gear 413 is installed on the side close to the inner side of the first limiting block, and the first gearless part 4132 corresponds to the inner side of the first limiting block. When the double door 2 is closed, the first gear part 4131 abuts against the second limiting end face, and the second limiting end face limits the first half gear 413 to prevent the first half gear 413 from continuing to rotate clockwise, thereby stabilizing the double door 2 in the closed state; when the double door 2 is opened, the first gear part 4131 abuts against the first limiting end face, and the first limiting end face limits the first half gear 413 to prevent the first half gear 413 from continuing to rotate counterclockwise, thereby stabilizing the double door 2 in the state of being fully opened to the maximum flip angle.

[0081] It is understood that the second limiting block extends vertically and is disposed on the right side wall of the housing 1, and the center of the second limiting block is embedded in the right side wall of the housing 1. The upper and lower ends of the second limiting block protrude from the side wall of the housing 1, respectively, and are the third limiting end face and the fourth limiting end face. The second half gear 423 is installed on the side close to the inner side of the second limiting block, and the second gearless part 4232 corresponds to the inner side of the second limiting block. When the double door 2 is closed, the second gear part 4231 abuts against the fourth limiting end face, and the fourth limiting end face limits the second half gear 423 to prevent the second half gear 423 from continuing to rotate counterclockwise, thereby stabilizing the double door 2 in the closed state; when the double door 2 is opened, the second gear part 4231 abuts against the third limiting end face, and the third limiting end face limits the second half gear 423 to prevent the second half gear 423 from continuing to rotate clockwise, thereby stabilizing the double door 2 in the state of being fully opened to the maximum flip angle.

[0082] In some embodiments of the present invention, the vehicle refrigerator 100 further includes a hovering mechanism; the hovering mechanism includes a first elastic element 51, one end of the first elastic element 51 is connected to a first half gear 413, and the other end of the first elastic element 51 is connected to the cabinet 1; and / or, the hovering mechanism includes a second elastic element 52, one end of the second elastic element 52 is connected to a second half gear 423, and the other end of the second elastic element 52 is connected to the cabinet 1.

[0083] Specifically, since the first door 21 and the second door 22 can be opened or closed synchronously by the drive of the transmission mechanism, a first elastic element 51, a second elastic element 52, or both can be provided. In this embodiment, a first elastic element 51 and a second elastic element 52 are included. The first elastic element 51 includes a first tension spring 511, and the second elastic element 52 includes a second tension spring 521. Taking the first tension spring 511 as an example, a first mounting hole is provided on the first half gear 413, and a mounting shaft passes through the first mounting hole. A first hanging hole is provided at one end of the mounting shaft extending out of the first half gear 413. One end of the first tension spring 511 is installed in the first hanging hole, thereby connecting with the first half gear 413. A second hanging hole is provided on the housing 1, and the other end of the first tension spring 511 is installed in the second hanging hole, thereby connecting with the housing 1. The second hanging hole is located below the first half gear 413 and is spaced a certain distance from the first half gear 413. Since the second tension spring 521 has the same structure as the first tension spring 511 and is arranged symmetrically, it will not be described in detail here.

[0084] When the double door 2 is in the open state, the first hanging hole is located on the left side of the first connecting shaft 411. When the double door 2 is in the closed state, the first hanging hole is located on the right side of the first connecting shaft 411. This causes a pulling force when the first half gear 413 rotates to the limit point of the opening, thereby realizing the suspension function of the double door 2 in the open state. The suspension angle is 90°-100°, which stabilizes the first door 21 and the second door 22 at the above angle, making it convenient for the user to take out the items in the box 1.

[0085] In addition, when the first half gear 413 rotates to the limit point of closing the door, there is a pulling force, which can realize the tensioning function of the double door body 2 in the closed state. This means that when the double door body 2 is closed, the first tension spring 511 exerts a certain tension on the first door body 21, which further improves the sealing function of the double door body 2.

[0086] Understandably, hovering angles can be, for example, 90°, 91°, 93°, 94°, 95°, 97°, 99°, 100°, etc.

[0087] In some embodiments of the present invention, the vehicle refrigerator 100 further includes a drive mechanism, which includes a drive motor 7 and a third half gear 8. The drive motor 7 is connected to the third half gear 8 in a transmission manner, and the third half gear 8 meshes with the first gear 412.

[0088] Specifically, in this application, the vehicle refrigerator 100 also includes a controller, a drive motor 7 is mounted on the cabinet 1 and located below the first gear 412, the controller is electrically connected to the drive motor 7, and a third half gear 8 is mounted on the motor shaft of the drive motor 7. The third half gear 8 meshes with the first gear 412. By setting the drive motor 7 and the third half gear 8, the vehicle refrigerator 100 can be driven to automatically open and close the door. When the user presses the open button on the cabinet 1, the controller receives the open command and controls the drive motor 7 to drive the third half gear 8 to rotate. The third half gear 8 drives the first gear 412, which meshes with it, to rotate, and then drives the first half gear 413 and the second gear 422, which mesh with the first gear 412, to rotate, thereby driving the first door 21 and the second door 22 to open synchronously, realizing the automatic opening of the vehicle refrigerator 100. When the user presses the close button on the cabinet 1, the controller receives the close command and controls the drive motor 7 to drive the third half gear 8 to rotate in the opposite direction. The third half gear 8 drives the first gear 412, which meshes with it, to rotate, and then drives the first half gear 413 and the second gear 422, which mesh with the first gear 412, to rotate, thereby driving the first door 21 and the second door 22 to close synchronously, thus realizing the automatic closing process of the vehicle refrigerator 100.

[0089] In some embodiments of the present invention, the first gear 412 includes a main tooth profile 4121 and a large tooth profile 4122 connected to each other. The tooth profile of the large tooth profile 4122 is larger than that of the main tooth profile 4121. The third half gear 8 meshes with the large tooth profile 4122.

[0090] Specifically, the main toothed portion 4121 meshes with the first half gear 413 and the second gear 422 respectively. The third half gear 8 includes a third gear portion 81 and a third gearless portion 82. The third gear portion 81 is adapted to and meshes with the tooth profile of the large toothed portion 4122. The diameter of the tip circle of the large toothed portion 4122 is larger than the diameter of the tip circle of the main toothed portion 4121. The tip circle refers to the circle where the tip of the tooth is located. When the double door body 2 is in the closed state, such as Figures 10 to 12 As shown, the third gear 81 is disengaged from the large toothed part 4122. When the controller receives the door opening command, the controller controls the drive motor 7 to drive the third half gear 8 to rotate counterclockwise, so that the third gear 81 and the large toothed part 4122 are engaged. The third half gear 8 drives the first gear 412 to rotate clockwise, which in turn drives the first half gear 413 to rotate counterclockwise, which in turn drives the first connecting shaft 411 to rotate counterclockwise, thereby causing the first door 21 and the second door 22 to open synchronously. Figures 7 to 9 As shown, the double doors 2 are in the open state at this time.

[0091] When the controller receives the door closing command, the controller controls the drive motor 7 to drive the third half gear 8 to rotate clockwise. The third half gear 8 drives the first gear 412 to rotate counterclockwise, which in turn drives the first half gear 413 to rotate clockwise, which in turn drives the first connecting shaft 411 to rotate clockwise, thereby causing the first door 21 and the second door 22 to close synchronously. At this time, the third gear part 81 is disengaged from the large tooth part 4122.

[0092] It should be noted that the length of the large toothed portion 4122 is greater than the length of the third gear portion 81, and the length of the large toothed portion should ensure that when it meshes with the third gear portion 81 to drive the double door body 2 to open, the double door body 2 can be fully opened.

[0093] By setting a third half gear 8, which includes a third gear part 81 and a third gearless part 82, and a large toothed part 4122, the large toothed part 4122 makes it easier for the third gear part 81 to mesh with the first gear 412, so that the third gear part 81 can mesh / disengage with the large toothed part 4122, thereby realizing the automatic opening and closing functions of the vehicle refrigerator 100. Furthermore, since the third gear part 81 is disengaged from the large toothed part 4122 when the door body 2 is in the open or closed state, it will not affect the manual opening or closing operation. Users can choose the opening or closing method as needed, which is convenient for users and improves the user experience.

[0094] In some embodiments of the present invention, the vehicle refrigerator 100 further includes a sensing device, which includes a trigger 91, a first sensing element 92, and a second sensing element 93. The trigger 91 is disposed on the second gear 422 and rotates synchronously with the second gear 422. The first sensing element 92 is disposed on the cabinet 1. When the first door 21 and the second door 22 are in the closed state, the first sensing element 92 is triggered by the trigger 91. The second sensing element 93 is disposed on the cabinet 1. When the first door 21 and the second door 22 are in the open state, the second sensing element 93 is triggered by the trigger 91.

[0095] Specifically, in this application, the trigger 91 is a slider 911, and the first sensing element 92 and the second sensing element 93 are position sensors, namely the first sensor 921 and the second sensor 931. The outer edge of the slider 911 protrudes relative to the outer edge of the teeth of the second gear 422, so that the slider 911 can contact the first sensor 921 and the second sensor 931 to trigger them. When the slider 911 is rotated to the closed state, it will contact and trigger the first sensor 921. When the slider 911 is rotated to the open state, it will contact and trigger the second sensor 931.

[0096] To further understand the vehicle refrigerator 100 of this application, the working process of automatic door opening and automatic door closing of the vehicle refrigerator 100 of this application will be described below with reference to the accompanying drawings.

[0097] Automatic door opening process: such as Figures 10 to 12 In the figure, the double door body 2 is in the closed state. At this time, the third half gear 8 is disengaged from the first gear 412, and the double door body 2 can be manually opened or closed. When the controller receives the automatic door opening command, it first checks whether the double doors 2 are closed. If they are closed, the slider 911 contacts and triggers the first sensor 921. At this time, the controller controls the drive motor 7 to drive the third half gear 8 to rotate counterclockwise, so that the third gear part 81 and the large tooth part 4122 are engaged. The third half gear 8 drives the first gear 412 to rotate clockwise, which in turn drives the first half gear 413 to rotate counterclockwise, which in turn drives the first connecting shaft 411 to rotate counterclockwise, so that the first door 21 and the second door 22 open synchronously. When the door is about to reach the opening limit point, the third half gear 8 will disengage from the first gear 412. The first door 21 and the second door 22 will rotate to the opening limit point under the action of the first tension spring 511 and the second tension spring 521. Then the second sensor 931 is triggered, and the third half gear 8 stops rotating. Since the third half gear 8 has disengaged from the first gear 412 at this time, it will not be affected when the user manually closes the refrigerator door.

[0098] Automatic door closing process: When the controller receives the automatic door closing command, it first checks whether the double door 2 is in the open state. If it is in the open state, the slider 911 contacts the second sensor 931 and triggers the second sensor 931. The controller controls the drive motor 7 to drive the third half gear 8 to rotate clockwise. The third half gear 8 drives the first gear 412 to rotate counterclockwise, which in turn drives the first half gear 413 to rotate clockwise, which in turn drives the first connecting shaft 411 to rotate clockwise, thereby causing the first door 21 and the second door 22 to close synchronously. At this time, the third gear part 81 is disengaged from the large tooth part 4122. Since the third half gear 8 and the first gear 412 are disengaged at this time, it will not be affected when the user manually opens the refrigerator door.

[0099] It is understandable that the way the first sensing element 92 and the second sensing element 93 sense the trigger element 91 is not limited. It can be contact sensing, that is, sensing is achieved by the sensing element and the trigger element 91 being in contact, or it can be non-contact sensing, that is, sensing is achieved without the sensing element and the trigger element 91 being in contact. For example, the sensing element can also be a proximity sensor, and the trigger element 91 can also be a magnet. By setting the proximity sensor and the magnet to work together, the switching between the on and off states is achieved according to the position change of the magnet. When the proximity sensor can sense the magnet, it is in the on state; when the proximity sensor cannot sense the magnet, it is in the off state. The proximity sensor sends the on / off signal to the controller, and the controller can obtain the status of the double door 2 as open / closed.

[0100] A second aspect of the invention provides a vehicle including the vehicle-mounted refrigerator 100 as described above.

[0101] It is understood that the in-vehicle refrigerator 100 proposed in this invention can be integrated with the vehicle, for example, by setting it in the armrest box of the front or rear row of the vehicle, or in other locations with ample space, such as the glove box of the passenger seat, making the interior of the vehicle more aesthetically pleasing. In addition, the in-vehicle refrigerator 100 can conveniently utilize the vehicle's power supply and supporting systems, with a more compact structure and higher integration.

[0102] The second aspect of the present invention provides a vehicle interior equipped with the vehicle refrigerator 100 proposed in the first aspect of the present invention. The vehicle refrigerator 100 comprises a sealing assembly and a driving mechanism. The sealing assembly includes a first sealing element 31 disposed on a first door 21 and a second sealing element 32 disposed on a second door 22. The driving mechanism is tractively connected to the first door 21 and the second door 22 and can drive the doors to open or close synchronously. When the driving mechanism drives the first door 21 and the second door 22 to close synchronously, the first door 21 and the second door 22 press against the first sealing element 31 and the second sealing element 32, forming an interference fit between them. This ensures effective sealing of the first sealing element 31 and the second sealing element 32, sealing the gap between the first door 21 and the second door 22, thereby improving the sealing performance of the double-leaf door 2, ensuring the cooling effect of the vehicle refrigerator 100, and reducing energy consumption.

[0103] In some embodiments of the present invention, the vehicle also includes a center console (not shown), and a vehicle refrigerator 100 is installed inside the center console.

[0104] It is understood that the vehicle refrigerator 100 proposed in this invention is a pre-installed vehicle refrigerator, integrated into the armrest box, which can make full use of the space inside the armrest box and is convenient for front and rear passengers to use.
