Description

Technical Field

[0001] This invention relates to the field of vehicle technology, and in particular to a center console structure with an integrated hot water device, a secondary instrument panel, and a vehicle. Background Technology

[0002] As living standards improve, the demand for hot water in cars is increasing. Currently, the hot water devices available in cars are mostly independent, such as car kettles. These kettles heat water by connecting to a power supply. However, this type of non-integrated hot water system cannot be adapted to different car models and takes up storage space when not in use.

[0003] In addition, there are designs that integrate the hot water device inside the armrest box, which utilizes the redundant space inside the armrest box or sub-dashboard to integrate the heating structure, piping, water storage bottle, etc. in the redundant space. Although this arrangement utilizes redundant space, it still occupies space inside the armrest box or sub-dashboard, especially the water storage bottle, which requires customized storage space. These integrated structures occupy a certain amount of space and will inevitably affect the arrangement of other structures inside the sub-dashboard. Summary of the Invention

[0004] To address the shortcomings of existing technologies, the purpose of this invention is to provide an integrated armrest box structure, sub-dashboard, and vehicle that integrates a hot water device. This design achieves an integrated design of the armrest box cover and the hot water device. The main board base serves as both the main structure of the hot water device and the functional cover of the armrest box, with one component fulfilling two functions. This avoids the structural redundancy caused by the separation of the cover and the hot water device in traditional solutions.

[0005] To achieve the above objectives, the present invention is implemented through the following technical solution: Firstly, an integrated hot water device armrest box structure is provided. The armrest box has an internal power inlet, and the top edge of the armrest box is movably connected to the hot water device via a connecting structure. The power inlet supplies power to the hot water device. The hot water device is an instant hot water structure, with its main body being a main board base. The top of the main board base has an openable flap structure with a water outlet. The main board base is located at the edge of the armrest box and also serves as the cover of the armrest box. Compared to existing technologies that integrate heating structures, pipes, and water storage bottles inside the armrest box, this invention completely solves the problem of the hot water device encroaching on the internal space of the armrest box, allowing the internal space of the armrest box to be completely preserved and used for storing other items, greatly improving the utilization rate of the vehicle's interior space.

[0006] As a further implementation, the flap structure is located on one side of the top of the main board base, and the end of the flap structure is hinged to the end of the main board base. When the flap structure is opened, the water outlet can be close to the cup slot on the front side of the armrest box; when the flap structure is closed, the top surface is flush with the top surface of the other side of the main board base.

[0007] As a further implementation, the armrest box frame includes an outer frame and an inner frame, with the inner frame being lower than the outer frame, and the bottom edge of the main board base being movably connected to the stepped structure formed between the outer frame and the inner frame.

[0008] As a further implementation, the motherboard base integrates a heating structure, and the motherboard base and the flip-plate structure integrate a water supply pipe structure. The heating structure is located close to the water supply pipe structure and is used for heating.

[0009] As a further implementation, the top of the motherboard base includes a first board surface and a second board surface. The first board surface integrates an operation interface, and the second board surface is provided with a water filling interface, through which a water bottle or a water supply pipe can be connected. One end of the water supply pipe is connected to the water inlet, and the other end is connected to the water outlet. The bottom surface of the flap structure is provided with an interface groove, and when the flap structure is closed, it avoids the water inlet.

[0010] As a further implementation, the stepped structure is provided with a magnetic attraction structure to achieve magnetic connection with the motherboard socket; Alternatively, one side of the bottom of the stepped structure is hinged to the stepped structure via a hinged structure; Alternatively, a groove is provided at the stepped structure, extending in the front-to-back direction, and the bottom of the main board base slides in conjunction with the groove via a slider.

[0011] As a further implementation, a notch is provided on the rear side of the armrest box frame, and the water supply pipe of the water tank placed inside the armrest box extends through the notch to the outside of the armrest box and connects to the water filling interface.

[0012] Secondly, a secondary instrument panel is provided with a handrail box structure of an integrated hot water device as described above. The handrail box structure is located in the middle of the secondary instrument panel. A cup groove is provided at the front of the secondary instrument panel, and a support structure is provided at the rear. The top height of the support structure is adapted to the height of the main board base, or is lower than the bottom surface of the main board base.

[0013] As a further implementation, a notch and a baffle are provided on the rear side of the armrest box frame, and the notch and the baffle are on the same plane.

[0014] Thirdly, a vehicle is provided with a secondary instrument panel as described above, and a hot water device is provided on the top of the armrest box structure of the secondary instrument panel, which is used as the armrest box cover.

[0015] The beneficial effects of the present invention are as follows: This invention places the mainboard of the hot water device at the top of the armrest box frame, which also serves as the armrest box cover, completely freeing it from encroaching on the internal storage space of the armrest box. Compared to existing technologies that integrate the heating structure, piping, and water tank inside the armrest box, this invention completely solves the problem of the hot water device occupying internal space, allowing the interior space of the armrest box to be fully preserved and used for storing other items, greatly improving the utilization rate of vehicle interior space. Furthermore, due to the use of an instant heating structure, there is no need to install a large-capacity water tank inside the vehicle, further saving space.

[0016] This invention achieves an integrated design of the armrest box cover and the hot water device. The main board base serves as both the main structure of the hot water device and the functional cover of the armrest box, realizing two functions in one component and avoiding the structural redundancy caused by the separation of the cover and the hot water device in traditional solutions. This integrated design not only saves the manufacturing cost of a separate cover but also reduces the number of parts, lowers the overall vehicle weight, and simplifies the assembly process. Furthermore, as an in-vehicle ecosystem component, the main board base can be replaced with other functional modules according to user needs, further enriching the scalability of in-vehicle functions.

Detailed Implementation

[0021] It should be noted that the following detailed description is illustrative and intended to provide further explanation of the invention. Unless otherwise specified, all technical and scientific terms used in this invention have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains.

[0022] As mentioned in the background section, some existing technologies integrate the hot water device inside the armrest box, that is, they utilize the redundant space inside the armrest box or sub-dashboard to integrate the heating structure, piping, water storage bottle, etc. in the redundant space. Although this arrangement utilizes redundant space, it still occupies space inside the armrest box or sub-dashboard, especially the water storage bottle, which requires customized storage space. These integrated structures occupy a certain amount of space and will inevitably affect the arrangement of other structures inside the sub-dashboard. In order to solve the above technical problems, the following embodiments are proposed.

[0023] Example 1 In a typical embodiment of the present invention, reference is made to Figures 1-7 As shown, an integrated hot water device armrest box structure is located in the middle of the sub-instrument panel 1. A cup holder 2 is located at the front of the sub-instrument panel 1, and the hot water device 3 is positioned at the top of the armrest box structure. An electrical connection port is provided inside the armrest box. The top edge of the armrest box is movably connected to the hot water device via a connecting structure, and the electrical connection port supplies power to the hot water device. The hot water device is an instantaneous hot water structure, with its main body being a main board base. The top of the main board base has an openable flap structure with a water outlet. The main board base, located at the edge of the armrest box, also serves as the cover of the armrest box; this is one of the core technical features of this invention.

[0024] Specifically, the top of the main board base 31 of the hot water device 3 includes a first plate and a second plate, and the dividing line between the first plate and the second plate extends along the length of the vehicle body. In this embodiment, the areas of the first plate and the second plate are basically the same, and the thickness of the main board base 31 located on the first plate is greater than the thickness of the main board base 31 located on the second plate. This difference in thickness is designed to accommodate the internal heating structure and control unit.

[0025] The flip-up structure 32 is located on one side of the second plate at the top of the main board base 31, and the end of the flip-up structure 32 is hinged to the end of the main board base 31 via a hinge 35. The area of ​​the flip-up structure 32 is adapted to the area of ​​the second plate, and the thickness of the flip-up structure 32 is equal to the difference between the thickness of the second plate and the thickness of the first plate of the main board base 31. The advantage of this design is that when the flip-up structure 32 is closed, its top surface is completely flush with the top surface of the first plate, forming a flat handrail surface, eliminating the feeling of unevenness and improving both comfort and aesthetics.

[0026] The flap structure 32 has a water outlet 33 at the end away from the hinge. For example... Figure 1 As shown, when the flap structure 32 is in the closed state, the main board base 31 and the flap structure 32 together form a plate-like structure, which is arranged at the top of the armrest box structure. At this time, the hot water device 3 completely functions as the armrest box cover, and the user can place their arm naturally on the flat surface formed by the main board base 31 and the flap structure 32 as an armrest.

[0027] like Figure 2 As shown, when the hot water function is needed, the user can flip up the flap structure 32. After the flap structure 32 is opened, it forms a certain angle with the main board base 31. In this embodiment, this angle is an obtuse angle. The flap structure 32 is tilted forward, allowing the water outlet 33 to be close to the cup slot 2 on the front side of the armrest box. The water outlet 33 is located directly above or slightly behind the cup slot 2. The user only needs to place the cup in the cup slot 2, and the hot water from the water outlet 33 will fall accurately into the cup. The user does not need to hold the cup and aim it at the water outlet, which greatly improves the convenience and safety of use and avoids the risk of hot water splashing and causing burns.

[0028] When the flip-up structure 32 is closed, its top surface is flush with the top surface (first plate surface) on the other side of the main board base 31.

[0029] The motherboard socket 31 integrates a heating structure, which can be an electric heating element, a PTC heater, or other instantaneous heating element. The motherboard socket 31 and the flip-plate structure 32 integrate a water supply pipe structure, forming a continuous water channel. The heating structure is positioned close to the water supply pipe structure; as water flows through the water supply pipe structure, the heating structure rapidly heats the water, ensuring that the water exiting from the outlet 33 reaches the user-set temperature.

[0030] Understandably, a pump is also installed inside the motherboard socket 31, located at the water supply pipe, to provide power and ensure that water can be smoothly delivered from the water inlet 36 to the outlet 33. The power of the water pump is designed to match the length and resistance of the water supply pipe structure, ensuring sufficient water flow while avoiding excessive power consumption and energy waste.

[0031] It is understood that the first panel in this embodiment integrates an operation interface 34, which can be in the form of a touch screen, buttons, or knobs. Through the operation interface 34, users can perform various settings and operations, including but not limited to: temperature selection (e.g., 45℃, 60℃, 80℃ or a custom temperature), water output control, working mode selection (e.g., milk brewing mode, coffee brewing mode, tea brewing mode, etc.), and child lock function switch. The operation interface 34 is designed with user-friendliness in mind, with clear icons and simple operation logic, making it easy for even the elderly or children to master.

[0032] Specifically, the operation interface 34 is integrated on the first board surface of the motherboard socket 31, and adopts the form of a touch screen. The screen size is designed according to the area of ​​the first board surface to ensure that the displayed content is clear and easy to read, while avoiding an excessively large screen that occupies too much space. The main interface of the operation interface 34 displays information such as the current working status and water temperature. Users can access different function menus through touch operation to perform various settings and operations.

[0033] The operation interface 34 has a water output control function, allowing users to set the single water output volume, such as 150 ml, 250 ml, 500 ml, or a custom volume. After setting the water output volume, the user only needs to click the water output button, and the hot water device 3 will automatically output water. The water output will automatically stop once the set value is reached, eliminating the need for continuous user operation and avoiding the problems of excessive or insufficient water output.

[0034] In addition, the operating interface 34 can also connect to the vehicle system or a mobile APP to achieve remote control and status monitoring. Users can view information such as the working status, remaining water volume, and cumulative water output of the hot water device 3 through the mobile APP. They can also remotely set and control the device through the mobile APP. For example, before arriving at the vehicle, users can start the hot water device 3 through the mobile APP to preheat the water, so that hot water can be used immediately upon arrival at the vehicle, greatly improving the user experience.

[0035] In this embodiment, the motherboard socket 31 also integrates electronic components such as a control unit, a temperature sensor, and a water level sensor. The control unit is responsible for the operation control of the entire hot water device 3, including receiving commands input by the user through the operation interface 34, controlling the working status of the heating structure, monitoring water temperature and water level, and controlling the start and stop of the water pump. The temperature sensor detects the water temperature in the water supply pipe structure in real time and feeds the temperature signal back to the control unit. The control unit adjusts the heating power of the heating structure according to the temperature signal to achieve precise temperature control. The water level sensor is used to detect the water level in the water supply pipe structure. When the water level is too low, the control unit will issue an alarm to prompt the user to add water to avoid dry burning and damage to the heating structure.

[0036] The rear end of the second panel is equipped with a water inlet 36. The water inlet 36 is a standardized interface structure that can be connected to the water bottle 4 or the water supply pipe 7. When using the water bottle 4 for water supply, the water bottle 4 has a corresponding connector that matches the structure of the water inlet 36. The user only needs to align the connector of the water bottle 4 with the water inlet 36 and gently press or rotate to achieve the connection. The connection process is simple, quick, and secure, and there will be no leakage.

[0037] Understandably, when using the water bottle 4 to supply water to the hot water device 3, the water bottle 4 is directly attached to the water inlet 36. When using the water supply pipe 7, one end of the water supply pipe 7 has a connector that matches the water inlet 36, and the other end extends into the water tank 5. The water tank 5 can be placed in the storage space 13 inside the armrest box, or in other suitable locations inside the vehicle, such as under the rear seats. The length of the water supply pipe 7 is selected according to the placement location of the water tank 5 to ensure that the water supply pipe 7 can smoothly connect the water inlet 36 and the water tank 5, while avoiding excessive length of the water supply pipe 7, which would increase water resistance or occupy too much space.

[0038] In this embodiment, the water supply pipe structure is connected to a water inlet 36 at one end and a water outlet 33 at the other end. After water enters the water supply pipe structure through the water inlet 36, it flows forward under the drive of the water pump. During the flow, it passes through the heating area of ​​the heating structure, and the water temperature rises rapidly. The heating power and heating time of the heating structure are precisely controlled by the control unit according to the temperature and water flow rate set by the user, ensuring that the water temperature coming out of the outlet 33 is accurate and stable.

[0039] like Figure 3 As shown, the armrest box has a power inlet 8 inside. A plug 38 extends from the bottom of the main board base via a wire. The plug 38 is connected to the circuit inside the main board base 31 via a cable. The plug 38, in conjunction with the power inlet 8, can supply power to the hot water device. The plug 38 and the power inlet 8 are designed with a foolproof structure to ensure that they can only be inserted when correctly aligned, avoiding circuit damage or safety hazards caused by incorrect connection. The hot water device in this embodiment is an instant hot water device, so there is no need to store water. When hot water is needed, simply place the water bottle on the water inlet, or connect the water storage pipe to the water inlet through the water supply pipe.

[0040] like Figure 2As shown, the bottom surface of the flap structure 32 is provided with an interface groove 37, the position, shape, and size of which precisely correspond to the water inlet 36 on the second plate surface. When the flap structure 32 is closed, the interface groove 37 avoids the water inlet 36, preventing the water inlet 36 from interfering with the bottom surface of the flap structure 32, thus achieving complete flushness between the first plate surface and the top surface of the flap structure 32 when closed. This avoidance design not only ensures the aesthetic appearance but also ensures that the water inlet 36 can still be used normally when the flap structure 32 is closed, allowing users to connect or disconnect the water bottle 4 or water supply pipe 7 without opening the flap structure 32.

[0041] like Figure 3 and Figure 4 As shown, at the rear of the sub-dashboard, that is, behind the armrest box structure, is a support structure. The top of the support structure is a rear support plate. The rear support plate 11 is a plate-like structure that can be used to place small items such as mobile phones and wallets.

[0042] When water is supplied using the water tank 5, and the water tank 5 is placed inside the armrest box, the water supply pipe needs to extend out from inside the armrest box. In this embodiment, a notch 112 is provided on the rear side of the armrest box frame, and the water supply pipe on the water tank placed inside the armrest box extends through the notch to the outside of the armrest box and connects to the water filling interface.

[0043] In an alternative example, the maximum height of the rear support plate 11 above and below the edge of the armrest box is such that an opening is formed between the front end of the rear support plate 11 and the main board mount of the hot water device, as shown below. Figure 6 As shown, a baffle 111 is provided at the opening, and a notch 112 is provided on the baffle 111. The size of the notch 112 is adapted to the outer diameter of the water supply pipe, which can limit the water supply pipe and allow the water supply pipe to extend out from the inside of the armrest box through this notch.

[0044] When the water supply pipe is connected to the water inlet, the main board and armrest box structure can be opened. Open the main board, extend the water supply pipe inside the armrest box from the notch, connect it to the water inlet, and then put the main board down.

[0045] Specifically, when connecting the water supply pipe 7 to the water inlet 36, the user first lifts the main board base 31 upwards to separate it from the step structure 124. Then, the user pulls the water supply pipe 7 from the notch 112 inside the armrest box and connects it to the water inlet 36. Finally, the user places the main board base 31 back onto the step structure, where the magnetic structure automatically adheres and secures it. The entire operation is simple and convenient, requiring no tools.

[0046] Understandably, the baffle 111 can block other areas and prevent items on the rear support plate 11 from falling into the armrest box.

[0047] In another preferred embodiment, the rear support plate 11 can also be flush with the top surface of the motherboard base, simply by providing a circular opening at the front end of the rear support plate 11 for the water supply pipe to extend out. The circular opening must be located on one side of the motherboard base. It is understood that the armrest box may not have a rear side frame.

[0048] like Figure 5 As shown, the armrest box frame 12 includes an outer frame 121 and an inner frame 122. The inner frame 122 is lower than the outer frame 121, and a stepped structure 124 is formed between the inner frame 122 and the outer frame 121. The cross-sections of the outer frame 121 and the inner frame 122 are Z-shaped. The stepped surface of the stepped structure 124 is flat, and this flat surface can support the bottom edge of the main board base 31. In this embodiment, the armrest box frame 12 does not have a rear side frame, but only left and right side frames and a front side frame. The advantage of this design is that it facilitates the extension of the water supply pipe 7 from the inside of the armrest box to the outside of the armrest box.

[0049] The bottom edge of the motherboard base 31 is movably connected to the stepped structure 124 formed between the outer frame 121 and the inner frame 122. After installation, the top surface of the motherboard base 31 is basically matched with the height of the outer frame 121, forming a relatively flat transition surface. The cross-sections of the inner frame 122 and the outer frame 121 are Z-shaped. This Z-shaped structure not only enhances the structural strength of the armrest box frame 12, but also provides stable support for the motherboard base 31.

[0050] In an optional example, the stepped structure is provided with a magnetic structure, which can be a magnet or a magnetic sheet, to achieve a magnetic connection with the bottom of the motherboard base. The bottom of the motherboard base needs to be provided with a metal structure or magnetic sheet that is compatible with the magnetic structure.

[0051] In this embodiment, the stepped structure 124 is provided with a magnetic attraction structure, which can be a magnet or a magnetic sheet. For example... Figure 5 As shown, at least one connector 123 is provided on both the left and right stepped surfaces, and the connector 123 is a magnetic attraction structure. A metal structure, such as an iron sheet or magnetic material, matching the magnetic attraction structure is provided at the corresponding position on the bottom of the motherboard base 31. When the motherboard base 31 is placed on the stepped structure 124, the metal structure at the bottom of the motherboard base 31 attracts the magnetic attraction structure on the stepped structure 124, achieving a detachable connection between the motherboard base 31 and the stepped structure 124.

[0052] The advantage of magnetic connection lies in its ease of assembly and disassembly. When users need to access the interior space of the armrest box, they simply lift the mainboard base 31 upwards to overcome the magnetic force and remove it to take items out of the armrest box. After use, the mainboard base 31 is placed back on the step structure 124, and the magnetic structure automatically adheres and secures it, requiring no additional latches or fasteners, making operation simple and quick. Simultaneously, the magnetic connection has a certain degree of magnetic attraction, ensuring that the mainboard base 31 remains stable during vehicle operation and will not detach or shift due to bumps or sudden braking.

[0053] When the motherboard socket is lowered and closed, it can serve as a cover for the armrest box structure, saving the cost of a set of covers. In addition, the motherboard socket also has a hot water function, making it a two-in-one device.

[0054] The hot water device 3 in this embodiment is an instant hot water device, which does not require pre-storing a large amount of hot water. When the user needs hot water, they only need to open the flap structure 32 and set the temperature and water flow rate through the operation interface 34. The hot water device 3 can then quickly heat the water and dispense it. Compared with traditional storage-type hot water devices, this instant hot water design has the following advantages: First, it does not occupy the internal space of the armrest box, thus preserving the storage space completely; second, it avoids water quality changes and energy loss that may occur due to long-term storage of hot water; and third, it heats up quickly, usually providing hot water within a few seconds to tens of seconds, meeting the user's immediate needs.

[0055] It is understood that the hot water device in this embodiment, as an in-vehicle eco-component, simultaneously functions as a center console cover and a water heater. In some optional examples, the step structure can be replaced with other electrically powered eco-components to further enrich the in-vehicle functionality. It should be noted that the bottom of other eco-components preferably has a magnetic structure that cooperates with the step, and the main body is preferably a plate structure, which can be used as a center console cover.

[0056] In another alternative example, a groove is provided at the stepped structure, extending in the front-to-back direction, and the bottom of the motherboard base slides into the groove via a slider. When disassembling the motherboard base, it needs to be slid backward to remove it from the stepped structure. At this time, it must be ensured that the height of the rear support plate 11 is lower than the bottom of the motherboard base, and the baffle 111 is lower than the motherboard base.

[0057] The slide groove can be set on the step surface of step 124 or on the inner sidewall of inner frame 122. The cross-sectional shape of the slide groove can be rectangular, T-shaped, dovetail-shaped, or other shapes suitable for sliding. The shape of the slider matches the cross-sectional shape of the slide groove to ensure that the slider can slide smoothly in the slide groove, while also having a certain degree of guidance and anti-disengagement.

[0058] When the user needs to access the interior space of the armrest box, the main board bracket 31 can be pushed backward. Guided by the sliding groove, the main board bracket 31 slides backward, gradually disengaging from the step structure 124, and can finally be completely removed from the armrest box frame 12. The removed main board bracket 31 can be placed in other locations on the dashboard 1, or temporarily placed elsewhere in the vehicle, without affecting the user's access to items inside the armrest box.

[0059] After use, the user aligns the motherboard base 31 with the slide groove and pushes it forward. Guided by the slide groove, the motherboard base 31 slides forward and eventually returns to its normal position on the armrest box frame 12, resuming its function as the armrest box cover.

[0060] The advantage of the sliding connection method is that the motherboard socket 31 is easier to install and remove, requiring no lifting; it can be pushed and pulled horizontally, saving effort. At the same time, the sliding groove provides precise guidance, ensuring that the motherboard socket 31 does not shift or jam during sliding, improving the smoothness of use.

[0061] In this embodiment, to ensure that the motherboard socket 31 does not slide accidentally under normal use, a limiting structure, such as a limiting protrusion, a limiting pin, or a spring lock, can be provided at an appropriate position on the slide groove. The limiting structure automatically locks when the motherboard socket 31 slides to the normal position to prevent the motherboard socket 31 from sliding backward. When the user needs to remove the motherboard socket 31, the locking of the limiting structure can be released by pressing the release button or applying a certain pushing force, and then the motherboard socket 31 can be slid backward to be removed.

[0062] In addition, the sliding connection method can also be used in combination with the magnetic connection method. That is, a magnetic structure is set at the front end of the sliding groove. When the motherboard base 31 slides to the normal position, the magnetic structure automatically attracts, further enhancing the stability of the connection.

[0063] In this embodiment, since the motherboard socket 31 is installed and removed by sliding, the height of the rear support plate 11 must be lower than the bottom surface of the motherboard socket 31 to ensure that the motherboard socket 31 does not interfere with the rear support plate 11 during the backward sliding process. At the same time, the height of the baffle 111 should also be lower than the bottom surface of the motherboard socket 31 to ensure that the motherboard socket 31 can slide smoothly over the baffle 111.

[0064] In another optional example, such as Figure 7 As shown, one side of the bottom of the stepped structure is hinged to the stepped structure via a hinge structure. A connecting shaft 39 is located in the middle of one side of the main board base of the hot water device. Both ends of the connecting shaft 39 extend to opposite sides and then are fitted with connecting sleeves 310. The connecting sleeves 310 and the extended parts of the connecting shaft are rotatably connected to form a corresponding hinge structure. A connecting part 311 is located at the bottom of the connecting sleeve. The connecting part can be a metal structure to facilitate magnetic attraction and fixation with the magnetic plates on the stepped surface.

[0065] Of course, the connecting part 311 can be directly fixed to the step surface of the step structure 124 by means of bolts, clips or welding.

[0066] In this embodiment, the connecting part 311 is magnetically fixed, which achieves both a hinged connection and retains a certain magnetic attraction force, thereby enhancing the stability of the connection.

[0067] When the user needs to access the interior space of the armrest box, the main board base 31 can be flipped up via the hinge structure. The user simply flips up the end of the main board base 31 away from the hinge, and the main board base 31 can rotate around the connecting shaft 39, gradually opening. The main board base 31 can be opened to a position at a certain angle to the step structure 124.

[0068] The advantage of the hinged connection is that the motherboard socket 31 remains connected to the armrest box frame 12 at all times and will not completely detach, so users do not need to worry about the placement of the motherboard socket 31. At the same time, the hinged connection makes the opening and closing of the motherboard socket 31 smoother, allowing users to operate it with one hand, thus improving ease of use.

[0069] When the interior space of the armrest box needs to be utilized, the main board base can be flipped open via the hinge structure to retrieve or place items into the armrest box. In this embodiment, the hinge position can be set on different sides of the main board base 31, such as the left side, right side, or front side. Users can choose the most suitable hinge position according to the vehicle's interior layout and their personal usage habits. Different hinge positions result in different opening directions for the main board base 31, adapting to different usage scenarios.

[0070] In one optional example, the stepped surface has corresponding snap-fit ​​connection points, allowing the magnet structure to be snapped onto the left, right, or front side of the stepped surface as needed. The connecting shaft and connecting sleeve on the main board base are correspondingly positioned on the same side, enabling the main board base to rotate around different sides and open the cover from different directions. This can be configured according to user requirements.

[0071] The advantage of the hinged connection is that the motherboard socket 31 remains connected to the armrest box frame 12 and will not completely detach, so users do not need to worry about the placement of the motherboard socket 31. At the same time, the hinged connection makes the opening and closing of the motherboard socket 31 smoother, allowing users to operate it with one hand, improving ease of use. Different hinge positions result in different opening directions for the motherboard socket 31, adapting to various usage scenarios.

[0072] For example, when the hinge position is set on the left side, the main board base 31 flips open to the left, suitable for use on the front passenger side; when the hinge position is set on the right side, the main board base 31 flips open to the right, suitable for use on the driver side; when the hinge position is set on the front side, the main board base 31 flips open forward, suitable for use on the rear passenger side.

[0073] To accommodate different hinge positions, the position of the power connector 8 also needs to be adjusted accordingly. The power connector 8 should be located in an appropriate position on the inner side wall of the armrest box to ensure that the plug 38 and the power connector 8 can be smoothly separated during the flipping and opening of the main board base 31, and that the connection will not be broken or the circuit damaged due to cable pulling.

[0074] The connecting shaft 39 and connecting sleeve 310 on the motherboard socket 31 also adopt a modular design, which can be easily disassembled and reinstalled on different sides of the motherboard socket 31 to meet the user's personalized customization needs.

[0075] It is understood that the motherboard socket can be hinged to the stepped structure alone, or it can be hinged in conjunction with magnetic attraction. In this embodiment, magnetic attraction and hinge are preferred, which allows for easy disassembly and reuse in other locations after disassembly.

[0076] The armrest box structure of this embodiment integrates the hot water device 3 and the armrest box cover into a single design. The main board 31 serves as both the main structure of the hot water device 3 and the cover of the armrest box, achieving two functions in one component, greatly saving cost and space. Simultaneously, the hot water device 3 is positioned on top of the armrest box, completely eliminating any space occupation within the storage area, allowing users to fully utilize the internal space for storing items. The ingenious design of the flip-up structure 32 allows the water outlet 33 to be positioned close to the cup holder 2, facilitating water access and enhancing the user experience. The magnetic connection method makes the assembly and disassembly of the main board 31 simple and quick, allowing users to open the armrest box at any time to access items and replace different functional components as needed, enhancing the product's flexibility and scalability.

[0077] In other optional examples, the functionality of the hot water device can be further enriched. The motherboard socket 31 contains a temperature sensor that monitors the temperature of the heating structure in real time. When the temperature of the heating structure exceeds a safety threshold (which can be determined based on the situation), the control unit will immediately cut off the power to the heating structure, stopping heating to prevent overheating damage or safety accidents. Simultaneously, the operating interface 34 will display an over-temperature warning, prompting the user to wait for the equipment to cool down.

[0078] The electrical system of the hot water unit 3 is equipped with a leakage current protection device. When the leakage current exceeds the safety threshold, the leakage current protection device will immediately cut off the power supply to prevent electric shock accidents caused by leakage. The sensitivity and action time of the leakage current protection device meet relevant safety standards to ensure user safety.

[0079] The outer surfaces of the flip-up structure 32 and the main board base 31 are made of heat-insulating material or a heat-insulating coating. Even when the hot water device 3 is in operation, the temperature of the outer surfaces remains within a safe range, and users will not feel hot to the touch. The water outlet 33 is designed with a splash-proof structure, ensuring a smooth water flow without splashing and preventing hot water from scalding users. The operation interface 34 is equipped with a child lock function. When the child lock is activated, all touch operations on the operation interface 34 are locked to prevent children from accidentally operating it and causing scalding or other safety accidents.

[0080] The electrical system of hot water unit 3 is equipped with an overload protection device. When the current exceeds the rated value, the overload protection device will automatically cut off the power supply to prevent equipment damage or fire caused by circuit overload. The overload protection device adopts a resettable design, which can automatically recover after the fault is cleared without the need to replace fuses or other components.

[0081] The main board base 31 is firmly connected to the armrest box frame 12 by means of magnetic attraction, hinge or sliding groove. Even when the vehicle brakes suddenly, turns sharply or drives on bumpy roads, the main board base 31 can remain stable and will not fall off or tip over, thus avoiding hot water splashing out and scalding passengers or damaging the vehicle's facilities.

[0082] The hot water device of this embodiment has the following beneficial effects: This invention places the mainboard of the hot water device at the top of the armrest box frame, which also serves as the armrest box cover, completely freeing it from encroaching on the internal storage space of the armrest box. Compared to existing technologies that integrate the heating structure, piping, and water tank inside the armrest box, this invention completely solves the problem of the hot water device occupying internal space, allowing the interior space of the armrest box to be fully preserved and used for storing other items, greatly improving the utilization rate of vehicle interior space. Furthermore, due to the use of an instant heating structure, there is no need to install a large-capacity water tank inside the vehicle, further saving space.

[0083] This invention achieves an integrated design of the armrest box cover and the hot water device. The main board base serves as both the main structure of the hot water device and the functional cover of the armrest box, realizing two functions in one component and avoiding the structural redundancy caused by the separation of the cover and the hot water device in traditional solutions. This integrated design not only saves the manufacturing cost of a separate cover but also reduces the number of parts, lowers the overall vehicle weight, and simplifies the assembly process. Furthermore, as an in-vehicle ecosystem component, the main board base can be replaced with other functional modules according to user needs, further enriching the scalability of in-vehicle functions.

[0084] The flip-up structure of this invention features an ingenious design. Hinged to one side of the main board base, the flip-up structure allows the water outlet to tilt forward, approaching the cup holder at the front of the dashboard. With the outlet directly above the cup holder, users can easily fill the cup without moving it, simply placing it in the cup holder. When closed, the top surface of the flip-up structure is flush with the first surface of the main board base, forming a flat armrest surface that does not interfere with the normal use of the armrest box. Furthermore, the main board base is connected to the armrest box frame via a movable connection structure, allowing users to easily open the main board base to access items inside the armrest box, providing flexibility and convenience.

[0085] This invention offers users a variety of connection methods, including magnetic connection, hinged connection, and sliding connection, or a combination of these three methods. The magnetic connection method allows for easy disassembly and assembly, enabling users to easily remove the motherboard socket for cleaning or replacement; the hinged connection method allows the motherboard socket to be flipped open for convenient access to items inside the armrest box; and the sliding connection method allows the motherboard socket to slide forward and backward, adapting to different usage scenarios. Each of these three connection methods has its own characteristics, allowing users to choose the most suitable method based on their actual needs and usage habits, greatly improving the product's applicability and user experience.

[0086] This invention supports two water supply methods: direct water supply from a water bottle and water supply from a storage tank via a water supply pipe. The water bottle method is suitable for short trips or temporary use, as users can easily replace the water bottle; the storage tank method is suitable for long journeys. The storage tank can be placed inside the armrest box or other locations in the vehicle and connected to the water inlet via a water supply pipe, providing a continuous water supply without the need for frequent water source changes. The two water supply methods can be flexibly switched to meet different usage needs.

[0087] The hot water device mainboard base of this invention features an integrated design with the armrest box frame, resulting in a simple and aesthetically pleasing appearance that harmonizes with the vehicle's interior. When the flip-up structure is closed, the entire mainboard base presents a flat, panel-like structure with no obtrusive exposed parts, maintaining a clean and tidy interior space. The operating interface is integrated onto the first panel of the mainboard base, with a logical layout for easy operation, enhancing the overall technological feel and premium quality of the vehicle.

[0088] The hot water device of this invention adopts an instant heating structure, eliminating the need for pre-storing large amounts of hot water and avoiding the scalding risk that may exist with traditional storage-type hot water devices. Simultaneously, the main board socket integrates a temperature sensor and control unit, enabling real-time monitoring and precise control of the water temperature to ensure that the outlet water temperature meets the user's set requirements. Furthermore, the main board socket is connected to the armrest box frame via a movable connection structure, ensuring stability even in the event of a collision or bump during vehicle operation, preventing it from detaching or shifting and guaranteeing safe use.

[0089] Example 2 In a typical embodiment of the present invention, reference is made to Figures 1-7 As shown, a secondary instrument panel is provided with a handrail box structure of an integrated hot water device as described in Embodiment 1. The handrail box structure is located in the middle of the secondary instrument panel. A cup groove is provided at the front of the secondary instrument panel, and a support structure is provided at the rear. The top height of the support structure is adapted to the height of the main board base, or is lower than the bottom surface of the main board base.

[0090] Specifically, when the motherboard socket is installed using a magnetic attachment method, the top height of the support structure matches the height of the motherboard socket; when it is installed using a sliding groove method, the top height of the support structure is lower than the bottom surface of the motherboard socket.

[0091] When the top height of the rear support plate 11 is basically matched with the top surface height of the motherboard base 31, a relatively flat platform is formed, and users can place small items such as mobile phones, wallets, and keys on the rear support plate 11 and the motherboard base 31, which increases the practicality of the secondary instrument panel 1.

[0092] The top of the rear support plate 11 is lower than the bottom of the main board base 31. This design is suitable for armrest box structures using hinged or sliding connections, ensuring that the main board base 31 does not interfere with the rear support plate 11 when opened or removed.

[0093] The support plate at the rear side of the armrest box has a notch and a baffle, which are on the same plane. The baffle can block items on the rear support plate from falling into the armrest box, thus acting as a limiter.

[0094] The notch provides an extension opening for the water supply pipe, ensuring that the water supply pipe can be smoothly connected to the water inlet. When the water tank 5 is used for water supply and the water tank 5 is placed inside the armrest box, the water supply pipe 7 can extend from inside the armrest box to outside the armrest box through the notch 112 and connect to the water inlet 36.

[0095] The height of the baffle 111 is designed based on the height of the rear support plate 11 and the motherboard base 31. It must be able to effectively block items on the rear support plate 11 while ensuring that it does not affect the normal use of the motherboard base 31. The baffle 111 can be made of plastic, metal or composite material, and its surface can be sprayed, electroplated or coated to coordinate with the overall style of the sub-dashboard 1.

[0096] The size of the notch 112 is designed according to the outer diameter of the water supply pipe 7, ensuring that the water supply pipe 7 can pass through smoothly while avoiding the notch 112 being too large and affecting the blocking effect of the baffle 111. In this embodiment, the shape of the notch 112 can be circular, elliptical, or rectangular, depending on design requirements and aesthetic requirements.

[0097] In some examples, the notch can be set in the form of a bayonet.

[0098] The overall design of the secondary instrument panel 1 is coordinated with the vehicle's interior, and its surface can be covered with soft-touch materials to enhance tactile feel and comfort. The color, texture, and material of the secondary instrument panel 1 can be customized according to the vehicle's positioning and user preferences to meet the individual needs of different users.

[0099] When hot water is needed, it can be supplied using a water bottle, or by using a water tank 5 and a water supply pipe 7. The water bottle 4 is a portable water supply container with a capacity typically ranging from 500 ml to 2 liters. The top of the water bottle 4 has a connector that matches the water inlet 36. The connector uses a quick-connect structure; the user simply aligns the connector of the water bottle 4 with the water inlet 36 and gently presses or rotates it to connect. The connection process is simple, quick, and secure, and there will be no leakage.

[0100] The advantage of the Water Bottle 4 lies in its portability, allowing users to carry it with them and refill their water supply anytime. The Water Bottle 4 is suitable for short trips or temporary use, such as commuting to and from get off work or short trips. Users can fill the Water Bottle 4 at home or in the office and then take it to their car. After use, the Water Bottle 4 can be easily replaced, eliminating the need for a fixed water storage facility in the vehicle.

[0101] In this embodiment, the water bottle 4 can be a regular mineral water bottle, a thermos, or a dedicated car water bottle. To connect to the water filling interface 36, a dedicated adapter needs to be installed on the bottle neck of the water bottle 4. One end of the adapter is threaded to the bottle neck, and the other end is a quick-connect connector that mates with the water filling interface 36. The adapter is designed for versatility and can be adapted to various common bottle neck sizes on the market, making it convenient for users.

[0102] The water tank 5 is a large-capacity water storage container, typically ranging from 5 liters to 20 liters. The water tank 5 can be placed in the storage space 13 inside the armrest box, or in other suitable locations inside the vehicle, such as under the rear seats or under the front passenger seat.

[0103] The water storage tank 5 has an outlet on its top or side. One end of the water supply pipe 7 is inserted into the outlet of the water storage tank 5, and the other end is connected to the water filling interface 36. The water supply pipe 7 is usually a flexible hose made of food-grade silicone or PVC, and its inner diameter is designed according to the water flow requirements, usually 6 mm to 10 mm.

[0104] The length of the water supply pipe 7 is selected according to the placement of the water storage tank 5 to ensure that the water supply pipe 7 can be smoothly connected to the water filling interface 36 and the water storage tank 5, while avoiding the water supply pipe 7 being too long, which would increase water resistance or occupy too much space.

[0105] The advantage of the water supply system using the water tank 5 is its large capacity, making it suitable for long-distance travel or frequent use. Users only need to replenish the water in the water tank 5 periodically, eliminating the need to frequently replace the water bottle 4, greatly reducing the number of operations and improving ease of use. Furthermore, the water tank 5 can be placed in a discreet location inside the vehicle, without affecting the aesthetics or practicality of the interior space.

[0106] In addition, the water storage tank 5 can also be equipped with a filtration device to perform preliminary filtration of the water source, removing impurities and odors and improving water quality. The filtration device can be a simple filter screen, an activated carbon filter cartridge, or a multi-stage filtration system, depending on the user's water quality requirements.

[0107] In this embodiment, the user can also equip both the water filling bottle 4 and the water storage tank 5 as needed to achieve dual water supply. During daily use, the water storage tank 5 is primarily used for water supply. When the water level in the storage tank 5 is insufficient or needs to be temporarily replenished, the system can quickly switch to the water filling bottle 4 to ensure uninterrupted hot water supply. This dual water supply method further enhances the practicality and reliability of the hot water device 3.

[0108] Example 3 In a typical embodiment of the present invention, reference is made to Figures 1-7 As shown, a vehicle is provided with the sub-dashboard described in Embodiment 2. This vehicle can be a sedan, SUV, MPV, or other type of passenger vehicle, or a special vehicle such as a commercial vehicle or RV.

[0109] In the vehicle of this embodiment, the secondary instrument panel 1 is consistent with the overall interior style of the vehicle, and the armrest box structure with integrated hot water device becomes a major highlight of the vehicle, enhancing the vehicle's sense of technology and comfort, and meeting the user's need to enjoy hot water at any time in the vehicle.

[0110] The vehicle's electrical system provides a stable power supply to the hot water device 3. The power connector 8 is connected to the vehicle's power system to ensure that the hot water device 3 can work normally. The vehicle's electrical system is also equipped with a power management function. When the vehicle is turned off or the battery is low, the power supply to the hot water device 3 will be automatically cut off to avoid excessive discharge affecting the vehicle's starting.

[0111] In this embodiment, the vehicle can also be equipped with an on-board water purification system to purify external water sources (such as rainwater, stream water, etc.) and then deliver them to the water storage tank 5 to provide a continuous water supply for the hot water device 3. The on-board water purification system includes a filtration device, a disinfection device, and a water storage device, which can effectively remove impurities, bacteria, and viruses from the water, ensuring water quality safety and hygiene, and meeting drinking water standards.

[0112] The in-vehicle water purification system allows users to obtain and purify water locally without carrying large amounts of bottled water during outdoor camping or long-distance travel, greatly reducing the burden and improving the convenience and comfort of the trip.

[0113] In addition, the vehicle can be equipped with solar panels to provide a green and environmentally friendly power source for the hot water system 3. The solar panels are installed on the roof or other suitable locations on the vehicle body, converting solar energy into electrical energy, which is stored in the vehicle's battery to power the hot water system 3 and other onboard electrical appliances. The solar power system reduces the vehicle's dependence on fuel or charging stations, reducing energy consumption and carbon emissions, aligning with the concept of green travel.

[0114] In the vehicle of this embodiment, the armrest box structure with integrated hot water device not only meets the practical needs of users, but also enhances the overall quality and market competitiveness of the vehicle, becoming a major selling point and attracting many consumers who value quality of life and travel comfort.

[0115] The above description is merely a preferred embodiment of the present invention and is not intended to limit the invention. Various modifications and variations can be made to the present invention by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the scope of protection of the present invention.
