Description

Technical Field

[0001] This utility model belongs to the field of vehicle refrigerator technology, specifically relating to a vehicle refrigerator with zoned temperature control. Background Technology

[0002] With the rise of new energy vehicles, cars are equipped with large-capacity batteries, enabling the installation of various power-consuming electrical appliances such as refrigerators, televisions, and massage seats. However, due to the limited space in cars, these appliances need to be redesigned to suit the car's usage scenarios.

[0003] A classic example is a refrigerator, typically integrated into the front center console armrest or the rear center armrest, with multiple retrieval slots. However, existing double-door car refrigerators (top and rear doors) suffer from an issue where the Z-axis dimension of the center console is too large, making them inconvenient to access. Current solutions involve adding a simple partition in the middle, but this provides a single temperature setting and does not allow for independent temperature zone control for the upper and lower sections. Utility Model Content

[0004] The purpose of this invention is to provide a vehicle refrigerator with zoned temperature control. A partition is deployed in the refrigeration area of ​​the vehicle refrigerator to achieve zoned temperature control based on the partition.

[0005] The technical solution adopted by this utility model to solve its technical problem is to propose a vehicle refrigerator with zoned temperature control, including a refrigeration space, a partition, a vacuum pump, and a main controller. The partition is built into the refrigeration space and divides the internal space of the refrigeration space into a first area and a second area. A first layer is deployed on the outside of the first area, and a second layer is deployed on the outside of the second area. The vacuum pump is connected to the first layer and the second layer respectively, and the main controller is electrically connected to the vacuum pump and the partition.

[0006] The partition isolates the first and second zones, allowing the vacuum pump to independently evacuate either zone.

[0007] Furthermore, it also includes a heat exchange mechanism, which is used for cooling or heating, and is connected to the refrigeration space.

[0008] Furthermore, a first valve is provided on the connecting pipe between the vacuum pump and the first interlayer, and a second valve is provided on the connecting pipe between the vacuum pump and the second interlayer. The first valve and the second valve are respectively electrically connected to the main controller.

[0009] Furthermore, when the partition divides the interior space of the refrigerated space into a first area and a second area, the partition reaches the dividing position; a position detector is deployed in the refrigerated space, and the position detector is used to detect whether the partition has reached the dividing position.

[0010] Furthermore, the partition is a plate-shaped structure, and a step is formed between the first region and the second region. The partition is rotatably mounted on a side wall above the step. When the partition rotates downward so that the edge of the lower side of the partition is fitted and sealed with the step surface of the step, the partition reaches the separation position.

[0011] Furthermore, the lower side of the partition and / or the step surface of the drop step are provided with sealing gaskets / sealing strips.

[0012] Furthermore, the partition extends from the side wall to the outside of the refrigerated space via a pivot and deploys the position detector, which is electrically connected to the main controller.

[0013] Furthermore, the partition is a foldable structure, and a square-shaped sliding sealing groove is formed on the inner wall between the first region and the second region. The two sides of the exposed end of the partition are slidably sealed in the sliding sealing grooves on the left and right sides, and the exposed end extends out of the first region and / or the second region to form a push-pull structure. The inner end of the partition is rolled on a spool located outside the refrigeration space. The spool is located on the rear side of the sliding sealing groove. When the exposed end reaches the sliding sealing groove on the front side opposite to the spool, the partition reaches the separation position.

[0014] Furthermore, the partition includes multiple folded structural plates of uniform thickness and connecting strips. The folded structural plates are aligned with the direction of the roll. The multiple folded structural plates and multiple connecting strips are arranged alternately to form the foldable partition. The inner end of the partition is connected to the roll, so that the partition is wound on the roll. The position detector is deployed on the roll and is electrically connected to the main controller.

[0015] Furthermore, the position detector is located in the sliding sealing groove on the front side. When the exposed end is embedded in the sliding sealing groove on the front side, the partition reaches the separation position. The position detector is electrically connected to the main controller.

[0016] The beneficial effects of this utility model are as follows: This invention proposes a vehicle refrigerator with zoned temperature control. The refrigerator's refrigeration space is divided into zones by partitions. The partitions also prevent the connection between the zones, thus achieving independent vacuum in each zone and enabling zoned temperature control.

[0017] By using foldable partitions and inflating / deflating the sidewall interlayer of the refrigerated area, effective control of zone stratification and temperature isolation can be achieved.

[0018] This application eliminates the refrigerator insulation layer, reduces the thickness of the inner wall of the refrigeration area, maximizes the use of the refrigeration space in the central armrest, reduces the thickness of the inner wall of the refrigeration area, and saves back space.

[0019] The vehicle refrigerator of this application can adjust the foldable partition according to actual needs and freely set the functional nature of the refrigeration space, such as refrigeration and storage. Attached Figure Description

Detailed Implementation

[0022] To more clearly illustrate the technical solutions in the embodiments of this utility model and the prior art, the specific implementation methods of this utility model will be described below with reference to the accompanying drawings. Obviously, the accompanying drawings described below are only some embodiments of this utility model. For those skilled in the art, other drawings and other implementation methods can be obtained based on these drawings without creative effort. Furthermore, the design orientation only indicates the relative positional relationship between the components, not the absolute positional relationship.

[0023] This utility model embodiment provides a vehicle refrigerator with zoned temperature control. Please refer to [link / reference]. Figure 1 , Figure 2 , Figure 3It mainly includes a refrigerated space, a partition, a vacuum pump, and a main controller. The partition is built into the refrigerated space and divides the internal space of the refrigerated space into a first area and a second area. A first mezzanine is deployed on the outside of the first area, and a second mezzanine is deployed on the outside of the second area. The vacuum pump is connected to the first mezzanine and the second mezzanine respectively. The main controller is electrically connected to the vacuum pump and the partition.

[0024] In this application, the refrigeration space is divided into zones by partitions, which isolate the first and second zones, allowing the vacuum pump to independently evacuate either zone. The electrical connection between the main controller and the partition serves to connect the main controller to the partition's status detector. Specifically, the status detector can be a position detector, used to detect the partition's position and determine its open / closed state. In this application, the partition's state includes only two types: closed and open. The closed state indicates that the partition has achieved zone division, enabling zoned temperature control; the open state indicates that the partition has not achieved zone division, and the refrigeration space is a single, unified space.

[0025] To realize the functions of the refrigerated space, other functional modules are also included, such as the opening and closing doors of the refrigerated space, heat exchange mechanisms, energy supply mechanisms, temperature control devices, etc., which can be referred to in [reference needed]. Figure 1 As shown in the image.

[0026] The heat exchange mechanism is used for cooling or heating, and can specifically be a refrigeration unit or a heating unit. If necessary, a cooling mechanism can be configured for the heat exchange mechanism, which can be implemented using the vehicle's cooling system or configured independently.

[0027] The power supply mechanism provides power to each functional module, which can be a vehicle battery (VBAT) or a small battery (12V / 18V / 36V, etc.), and can be selected according to the actual needs of each functional module.

[0028] Among them, the temperature control device can be used to adjust the power of the heat exchange mechanism in order to adjust the temperature in the cold storage space, and can be a frequency converter, etc.

[0029] The opening and closing door can be configured according to actual needs, such as being positioned directly above the armrest or below the rear air vent, and can be an orthogonal opening and closing mechanism.

[0030] In this application, the heat exchange mechanism is connected to the refrigerated space, specifically, to each area separated by partitions. For example, the heat exchange mechanism is connected to the first area and the second area via pipes, which can be any suitable conduit.

[0031] In this application, the partition divides the refrigerated space into a first area and a second area. This does not mean that the partition can only divide the refrigerated space into two areas. More partitioned areas can be obtained by changing the structure of the partition, increasing the number of partitions, or adjusting the structural layout of the refrigerated space. The technical solutions obtained in this way should also be within the protection scope of this application.

[0032] In this application, a sandwich layer is deployed within the side wall of the refrigerated space as a barrier layer to achieve insulation by eliminating heat conduction and convection. A vacuum pump is connected to the outside of the sandwich layer to charge and release gas, thereby affecting the temperature change in the corresponding area.

[0033] Based on this, the vacuum pump can be controlled by the main controller to adjust the insulation effect of each area, thereby achieving the effect of zoned temperature control.

[0034] In practice, the vacuum pump is connected to the first and second interlayers respectively, and independently controls the temperature control effect of each area.

[0035] For ease of control, control valves can be configured to adjust the working effect of each layer, thereby stabilizing the operation of the vacuum pump. The control valves are controlled by the main controller, which adjusts the vacuum effect of each layer.

[0036] For example, a first valve is installed on the connecting pipe between the vacuum pump and the first interlayer, and a second valve is installed on the connecting pipe between the vacuum pump and the second interlayer. The first valve and the second valve are electrically connected to the main controller. This allows for independent vacuuming of the first interlayer and the second interlayer, thereby differentiating the functional nature of each area within the refrigerated space.

[0037] Please see Figure 2 Taking the first region as an example where the second region is located above the first region, then the first region is the upper region and the second region is the lower region. Correspondingly, the first mezzanine corresponds to the upper mezzanine, and the second mezzanine corresponds to the lower mezzanine. In specific implementation: If the user wants to convert the upper area into storage space, the first valve opens, and the vacuum pump evacuates the upper area, blocking heat exchange and bringing the upper area to room temperature.

[0038] If the user wants to convert the lower area into storage space, the second valve opens, and the vacuum pump evacuates the lower area, blocking heat exchange and bringing the lower area to room temperature.

[0039] If a user wants to switch from the upper storage space to the lower storage space, the first valve opens, and the vacuum pump inflates the upper area. The second valve opens, and the vacuum pump evacuates the lower area, preventing heat exchange. This brings the lower area to room temperature.

[0040] If the user wants to switch from the lower storage space to the upper storage space, the second valve opens, and the vacuum pump inflates the lower area. Simultaneously, the first valve opens, and the vacuum pump evacuates the upper area, preventing heat exchange. This brings the upper area to room temperature.

[0041] Understandably, when a user sets the temperature and zone for the first time, opening the partition again will automatically default to the previous temperature and zone.

[0042] Adjustments to the functional properties of different zones can be made using a central controller. This central controller can be connected to multiple function buttons, which can be adjusted by the user. The central controller can be a PLC controller or an MCU-based system, capable of at least providing feedback on the partition status and controlling the valves. Adjustments to the refrigeration temperature can be made using the vehicle-mounted refrigerator controller, or the vehicle-mounted refrigerator controller and the central controller can be integrated into a single controller, thereby enabling all relevant functions of the vehicle-mounted refrigerator.

[0043] Figure 1 In the middle, partitions are deployed in the irregularly shaped transition area of ​​the refrigerated space, dividing the refrigerated space into a first zone and a second zone. The first mezzanine and the second mezzanine are represented by a mezzanine, with the first mezzanine corresponding to the first zone and the second mezzanine corresponding to the second zone.

[0044] In this application, zoned temperature control is implemented based on partitions. Therefore, the fundamental condition for realizing this function is that the partitions divide the refrigerated space into two relatively independent areas. The position of the partitions can be detected to determine whether the basic conditions for implementing zoned temperature control are met. The central controller can obtain the position information of the partitions in real time and provide feedback to the user so that the user can correctly adjust and use the storage space and refrigerated area.

[0045] Secondly, in this application, the means of implementing zoned temperature control is vacuuming, which requires that the partitions divide the zones in a sealed manner, that is, the two zones are independent of each other and not connected.

[0046] Therefore, a separation position can be marked to detect whether the partition has completed the area division, and the sealing is the default effect of the partition being in place. The default effect can be achieved by sealing means.

[0047] For example, when the partition divides the interior space of the refrigerated space into a first area and a second area, the partition reaches the dividing position; a position detector is deployed in the refrigerated space to detect whether the partition has reached the dividing position.

[0048] In one specific embodiment, the partition can be a plate-like structure that can be opened and closed as a whole to divide the refrigeration space into areas; when closed, the refrigeration space is divided into zones, and zoned temperature control can be performed; when open, the refrigeration space is an integrated space.

[0049] For example, a step is formed between the first region and the second region. A partition is rotatably disposed on one side wall above the step. When the partition rotates downward so that the edge of the lower side of the partition is fitted and sealed with the step surface of the step, the partition reaches the separation position.

[0050] Sealing gaskets / seal strips can be installed on the lower side of the partition and / or the step surface of the drop step to ensure a stable sealing effect for the lifting box.

[0051] A stepped drop surrounds the inner wall of the refrigerated space in a square frame shape. When a partition covers it, a sealed isolation between the two areas is achieved. To prevent air pressure from damaging this seal, a snap-fit ​​structure can be installed on the stepped drop to press the partition firmly onto it; or snap-fit ​​components can be installed between the partition and the stepped drop to achieve a stable fit and ensure a consistent seal.

[0052] The first area can be located above the second area, and the partition can be rotatably installed on the side wall of the first area. The rotating structure can be located in the refrigerated space. A downward connecting structure can be provided between the rotating structure and the partition so that the partition can be flatly attached to the drop step. The step surface of the drop step should also be at the same height.

[0053] The partition's rotating shaft extends beyond the refrigerated space onto its side wall, and a position detector is installed there. The position detector is electrically connected to the main controller. A sealing structure can be provided between the rotating shaft and the refrigerated space to ensure the independence of this area and prevent it from communicating with the external environment while allowing the shaft to rotate normally. In this embodiment, the position detector can be an angle sensor or an encoder, which uses the rotation angle of the shaft to determine whether the partition has reached the separation position, thus achieving a sealing effect.

[0054] Understandably, to facilitate the rotation of the partition, a foldable gripper can be installed on the partition. Normally, it is placed flat on the partition, and when it is necessary to lift the partition, the gripper is rotated to stand it up, making it easier to grip and apply force.

[0055] It should be clarified that the above embodiment is illustrated using the example of the partition being located on the upper surface of the drop step, where the partition rotates downwards to achieve area separation; if the step surface of the drop step faces downwards, the partition is located below the drop step, and the partition rotates upwards to achieve area separation. In specific implementations, adjustments can be made or options can be selected according to the actual situation.

[0056] In one feasible embodiment, the partition can also be a folding structure. When folded together, the refrigeration space is a single space without zoned temperature control; when unfolded, the refrigeration space is divided into zones, and zoned temperature control can be implemented.

[0057] The folding structure takes many forms, including flexible roll-up folding and fan-shaped folding.

[0058] It is feasible; the partition can be a roll-up structure that can be rolled up and pulled out. When pulled out, the refrigeration space is divided into zones, allowing for zoned temperature control; when rolled up, the refrigeration space is a single, integrated space.

[0059] It is feasible. The partition can be a folding fan structure that can be opened and closed. When opened, the refrigeration space is divided into zones for temperature control; when closed, the refrigeration space is a single, integrated space.

[0060] Taking the winding structure as an example, a square-shaped sliding sealing groove is provided on the inner wall between the first region and the second region. The two sides of the exposed end of the partition are slidably sealed in the sliding sealing grooves on the left and right sides, and the exposed end extends into the push-pull structure in the part of the first region and / or the second region. The inner end of the partition is wound on a roller located outside the refrigeration space. The roller is located on the rear side of the sliding sealing groove. When the exposed end reaches the sliding sealing groove on the front side opposite to the roller, the partition reaches the separation position.

[0061] The sliding sealing groove can have a built-in sealing strip to achieve a seal between it and the partition, without affecting its sliding.

[0062] The sliding sealing groove has a square frame structure, including groove structures on four sides. The roller can be located in the rear groove and outside the refrigeration space. A heat insulation layer can be deployed behind the sealing strip here. A snap-fit ​​structure can be provided in the front groove so that the inner end can be snapped into it, so that the sealing effect between the partition and the sliding sealing groove is stable.

[0063] In one specific embodiment, the partition includes multiple folded structural plates of uniform thickness and connecting strips. The folded structural plates are aligned with the direction of the roll. The multiple folded structural plates and multiple connecting strips are arranged alternately to form a foldable partition. The inner end of the partition is connected to the roll, so that the partition is wound on the roll.

[0064] The two ends of the folded structural panel rest on the grooves on the left and right sides, respectively. The grooves support the folded structural panel, thus supporting the entire partition and enabling it to bear weight. The connecting strip is only used to achieve the winding effect; its thickness is the same as the folded structural panel, ensuring a stable seal between the sealing strip and the partition.

[0065] In this embodiment, the position detector can be deployed on the reel and electrically connected to the main controller. Specifically, the position detector can be an angle sensor or an encoder. Alternatively, the position detector can be placed in the front sliding sealing groove, i.e., within the front groove. When the exposed end is embedded in the front sliding sealing groove, the partition reaches the separating position. The position detector is also electrically connected to the main controller; in this case, the position detector can be a photoelectric sensor, etc.

[0066] The main controller can obtain the status information of the partitions in real time, thereby directly feeding back the status of the partitions, which makes it easier for users to accurately judge and adjust the zoning of the refrigerated space.

[0067] It should be clarified that regardless of the structural form of the partition, the independence of the partition in dividing the refrigerated space should be guaranteed. A corresponding sealing structure can be adopted according to the structural form of the partition to achieve the independence between the divided areas. The sealing structure is determined based on the structural form of the partition. Therefore, adjusting the sealing structure based on the adaptability of the partition structure to achieve the sealing effect is the basic condition for realizing the technical solution of this application. Therefore, without creative effort, adjusting the sealing structure based on the adaptability of the partition structure to achieve the sealing effect should fall within the protection scope of this application.

[0068] The refrigerated space refers to the refrigerated storage space of the vehicle refrigerator. In this application, the limitation of being outside the refrigerated space should be interpreted as not occupying the refrigerated space and not affecting the shape and layout of the refrigerated space.

[0069] For example, a cold storage space has inner walls and outer walls. The understanding of being outside the cold storage space can be that it is outside the inner wall but inside the outer wall.

[0070] Specifically in this application, the refrigeration space is integrated into the armrest, which means it is located outside the refrigeration space but inside the outer wall of the armrest. The vehicle refrigerator is deployed inside the armrest, and the internal space of the armrest can be used to deploy these units, modules and structures located outside the refrigeration space.

[0071] In addition, the vehicle refrigerator of this application can be referred to during use. Figure 3 , Figure 3 This is a control flowchart of the vehicle-mounted refrigerator based on the state of the partition in this application.

[0072] It should be noted that, in this document, relational terms such as "first" and "second" are used merely to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitations, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes the element.

[0073] The above description, in conjunction with specific preferred embodiments, provides a further detailed explanation of the present invention. It should not be construed that the specific embodiments of the present invention are limited to these descriptions. For those skilled in the art, various simple deductions or substitutions can be made without departing from the concept of the present invention, and all such modifications and substitutions should be considered within the protection scope of the present invention.
