Description

Technical Field

[0001] This invention relates to the field of vehicle armrest boxes, and more particularly to a vehicle armrest box with high-efficiency heat dissipation. Background Technology

[0002] With the development of the automotive industry and the upgrading of in-vehicle configurations, the in-vehicle armrest box, as an important storage and functional carrier in the cockpit, has gradually integrated wireless charging modules to meet the driver's need for charging smart devices. Wireless charging technology inevitably generates a certain amount of heat loss during the electromagnetic energy conversion process, and vehicles often face complex road conditions and vibration environments during actual driving.

[0003] Existing car armrest boxes are typically small, enclosed spaces. This structural feature causes heat generated by the wireless charging module and electronic devices to accumulate in a localized area and cannot be dissipated in time. The continuous accumulation of high temperatures can trigger the temperature control protection mechanism of electronic devices, resulting in decreased charging efficiency or device malfunction. At the same time, conventional anti-slip mats rely solely on gravity and static friction at the bottom for restraint. When the vehicle travels over bumpy roads or makes sharp turns, electronic devices are prone to lateral sliding or bouncing out of the optimal wireless charging sensing area. Therefore, a car armrest box with high-efficiency heat dissipation is proposed to solve the above problems. Summary of the Invention

[0004] In view of the problems in the prior art, such as the relatively enclosed internal space of the vehicle armrest box causing a large amount of heat generated by the wireless charging module and electronic devices to accumulate and trigger the device's temperature control protection to reduce frequency, and the inability of conventional anti-slip mats to effectively prevent the electronic devices from sliding laterally out of the charging sensing area when the vehicle is bumpy or making sharp turns, the present invention aims to provide a vehicle armrest box with an improved structure that can effectively solve the above problems and provide efficient heat dissipation.

[0005] This invention provides a highly efficient heat dissipation vehicle armrest box, comprising a vehicle armrest box body and a cover plate hinged to the top of the vehicle armrest box body. A wireless charging device is provided at the bottom of the vehicle armrest box body. Ventilation slots are provided on the sides of the vehicle armrest box body. An anti-slip pad is fixedly connected to the bottom of the inner wall of the vehicle armrest box body. A heat dissipation assembly is provided at the bottom of the inner wall of the vehicle armrest box body. The heat dissipation assembly includes a mounting member fixedly connected to the bottom of the inner wall of the vehicle armrest box body, and the mounting member has a hollow shell structure. To provide an internal airflow channel, the mounting component has an air inlet on its side, which is connected to the ventilation groove. A guide plate and a mounting plate are fixedly connected to the inner wall side of the mounting component. The mounting plate is vertically fixed inside the mounting component. A fan is provided on the side of the mounting plate. A mounting groove is provided on the upper surface of the mounting component, which extends vertically downward into the interior of the mounting component. A cooling component is inserted into the interior of the mounting groove. The air inlet, the fan, the cooling component, and the guide plate are arranged sequentially along the airflow direction.

[0006] Preferably, a limiting member is fixedly connected to the upper surface of the mounting component, the limiting member provides a vertical guiding and supporting space, a limiting plate is inserted into the inside of the limiting member, the limiting plate is inserted downward along the inner wall of the limiting member, and the side of the limiting plate abuts against the outer surface of the cooling component, thereby limiting the vertical upward displacement of the cooling component inside the mounting groove by the limiting plate.

[0007] Preferably, an inlet pipe and an outlet pipe are fixedly connected to the upper surface of the cooling component, and a handle is fixedly connected to the top of the cooling component. The handle is located between the inlet pipe and the outlet pipe to provide a force point for hand gripping. Both the inlet pipe and the outlet pipe are connected to the interior of the cooling component.

[0008] Preferably, the outer surfaces of both the inlet pipe and the outlet pipe are provided with limiting sleeves. The limiting sleeves are fitted onto the outside of the pipe body and seal the openings of the inlet pipe and the outlet pipe to prevent the cooling water inside the cooling component from overflowing.

[0009] Preferably, a limiting component is provided on the side of the mounting member near the guide plate. The limiting component is used to provide mechanical clamping force to the electronic device placed on the anti-slip pad. The limiting component includes a fixing bracket fixedly connected to the side of the mounting member. The side of the fixing bracket has a movable groove extending in a vertical direction.

[0010] Preferably, a spring is fixedly connected to the top of the inner wall of the movable groove, the spring hangs vertically along the length of the movable groove, a movable frame is fixedly connected to the end of the spring, a pressing member is fixedly connected to the bottom of the movable frame, and the movable frame slides in cooperation with the inner wall of the movable groove.

[0011] Preferably, the bottom of the pressing member is provided with an arc-shaped surface, the arc-shaped surface protrudes towards the anti-slip pad and conforms to the outer surface contour of the electronic device, and the arc-shaped surface is provided with a rubber layer, the rubber layer is used to increase the coefficient of friction between the bottom of the pressing member and the surface of the electronic device and avoid rigid contact that could scratch the surface of the electronic device.

[0012] Preferably, the upper surface of the anti-slip pad is provided with protrusions, which are used to form an airflow gap between the bottom of the electronic device and the anti-slip pad to facilitate the removal of heat by cool air.

[0013] The present invention has the following beneficial effects:

[0014] 1. In this invention, by adding a composite cooling air duct consisting of a fan, a cooling component, and a guide plate inside the vehicle armrest box, and in conjunction with the side ventilation grooves and the protrusion structure on the surface of the bottom anti-slip pad, the technical defect of existing wireless charging devices in the vehicle environment that easily leads to overheating and frequency reduction of electronic devices is solved. Outside air is actively drawn in and cooled by heat exchange through the cooling component. Then, the inclined guide plate accurately directs the cold air to the area above the anti-slip pad. The cold air flows through the gaps between the protrusions and carries away the heat of the device, effectively improving the heat dissipation efficiency of electronic devices in a closed space.

[0015] 2. In this invention, the charging device is mechanically fixed by an elastic limiting component set on the side of the mounting component, which overcomes the problem of the mobile phone sliding off the charging sensing area due to road bumps during vehicle operation. After the operator lifts the pressing component to compress the spring and stores the force, the restoring force released by the spring drives the pressing component with the arc-shaped surface and rubber layer to press down to fit the surface of the device. This flexible pressing method increases frictional resistance to prevent the device from shifting, while also avoiding physical scratches on the device shell caused by rigid contact.

[0016] 3. In this invention, a plug-in water replacement mechanism is designed, which improves the inconvenience of adding or replacing coolant in traditional built-in water-cooling modules. The cooling component is locked in the mounting slot by a plug-in connection with a limiting plate. During maintenance, the cooling component can be removed simply by pulling out the limiting plate and lifting the handle upwards. With the limiting sleeve structure fitted on the outer surface of the inlet and outlet pipes, it not only ensures the rapid replacement of old and new coolant in the external environment, but also prevents the internal water from shaking and overflowing while the vehicle is in motion.

Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0024] Reference Figures 1 to 4 This invention provides a vehicle armrest box with high-efficiency heat dissipation, solving the problems in the prior art where the operation of the wireless charging device inside the vehicle armrest box causes the device to overheat and reduce its frequency, and where the charging device slides off the charging area due to vehicle bumps.

[0025] like Figure 1 and Figure 2 As shown, a vehicle armrest box with high heat dissipation includes a vehicle armrest box body 1 and a cover plate 2 hinged to the top of the vehicle armrest box body 1. The vehicle armrest box body 1 serves as an integral mounting base to support internal components, and the cover plate 2 is used to close the top opening of the vehicle armrest box body 1.

[0026] The bottom of the vehicle armrest box body 1 is equipped with a wireless charging device 3. The wireless charging device 3 is used to provide wireless power transmission for electronic devices placed in the upper area. An anti-slip pad 5 is fixedly connected to the bottom of the inner wall of the vehicle armrest box body 1. The anti-slip pad 5 is located in the upper area of ​​the wireless charging device 3. The anti-slip pad 5 is used to support the electronic devices and provide bottom support. The upper surface of the anti-slip pad 5 is provided with protrusions. The protrusions are used to form an air circulation gap between the bottom of the electronic devices and the anti-slip pad 5.

[0027] The side of the vehicle armrest box body 1 is provided with a ventilation groove 4, which penetrates the side wall of the vehicle armrest box body 1. The ventilation groove 4 is used to connect the external environment with the internal space of the vehicle armrest box body 1. A heat dissipation component 6 is provided at the bottom of the inner wall of the vehicle armrest box body 1. The heat dissipation component 6 is located in the side area of ​​the anti-slip pad 5. The heat dissipation component 6 is used to construct a forced air-water composite cooling duct.

[0028] The heat dissipation assembly 6 includes a mounting component 601 fixedly connected to the bottom of the inner wall of the vehicle armrest box body 1. The mounting component 601 has a hollow shell structure and provides an internal airflow channel. An air inlet 602 is provided on the side of the mounting component 601. The air inlet 602 is connected to the ventilation groove 4. Outside air enters the air inlet 602 through the ventilation groove 4. A guide plate 603 and a mounting plate 604 are fixedly connected to the inner wall side of the mounting component 601. The mounting plate 604 is vertically fixed inside the mounting component 601. A fan 605 is provided on the side of the mounting plate 604. The fan 605 is fixed to the mounting plate 604 by bolts. After the fan 605 is started, it generates negative pressure suction airflow inside the mounting component 601.

[0029] The upper surface of the mounting component 601 is provided with a mounting groove 606, which extends vertically downward into the interior of the mounting component 601. A cooling component 608 is inserted into the interior of the mounting groove 606. The cooling component 608 contains cooling water, and its outer wall exchanges heat with the flowing air. A guide plate 603 is fixed in an inclined position at the air outlet end inside the mounting component 601. The guide plate 603 is inclined towards the area above the anti-slip pad 5. The air inlet 602, fan 605, cooling component 608 and guide plate 603 are arranged in sequence along the airflow direction.

[0030] Reference Figure 3 and Figure 4 A limiting member 607 is fixedly connected to the upper surface of the mounting component 601. The limiting member 607 provides vertical guidance and support space. A limiting plate 612 is inserted into the inside of the limiting member 607. The limiting plate 612 is inserted downward along the inner wall of the limiting member 607. The side of the limiting plate 612 abuts against the outer surface of the cooling component 608. The limiting plate 612 restricts the cooling component 608 from vertically upward displacement inside the mounting groove 606.

[0031] A water inlet pipe 609 and a water outlet pipe 610 are fixedly connected to the upper surface of the cooling component 608. The water inlet pipe 609 and the water outlet pipe 610 are located on both sides of the top of the cooling component 608. A handle 611 is fixedly connected to the top of the cooling component 608. The handle 611 is located between the water inlet pipe 609 and the water outlet pipe 610. The handle 611 provides a force point for hand gripping. Both the water inlet pipe 609 and the water outlet pipe 610 are connected to the interior of the cooling component 608. The water inlet pipe 609 serves as a channel for injecting cooling water, and the water outlet pipe 610 serves as a channel for discharging heated water from the interior.

[0032] Limiting sleeves are provided on the outer surfaces of both the inlet pipe 609 and the outlet pipe 610. The limiting sleeves are fitted on the outside of the pipe body and seal the openings of the inlet pipe 609 and the outlet pipe 610. The limiting sleeves prevent the cooling water inside the cooling component 608 from overflowing during vehicle operation.

[0033] During the cooling water replacement operation, the operator pulls the limiting plate 612 upward to disengage it from the limiting member 607. The limiting plate 612 releases its locking to the cooling component 608. The operator then holds the handle 611 and pulls it upward. The cooling component 608 slides upward along the mounting groove 606. The operator removes the limiting sleeves on the outer surfaces of the inlet pipe 609 and the outlet pipe 610. New cold water is injected into the cooling component 608 through the inlet pipe 609. The original water inside the cooling component 608 is pressurized and pushed out through the outlet pipe 610. After the water replacement is completed, the cooling component 608 is reinserted into the mounting groove 606, and the limiting plate 612 is reinserted into the limiting member 607 to restore its locking to the cooling component 608.

[0034] A limiting component 7 is provided on the side of the mounting component 601 near the guide plate 603. The limiting component 7 is used to provide mechanical clamping force to the electronic device placed on the anti-slip pad 5. The limiting component 7 includes a fixing bracket 701 fixedly connected to the side of the mounting component 601. The fixing bracket 701 provides a vertical guide support frame. The side of the fixing bracket 701 is provided with a movable groove 702, which extends vertically.

[0035] A spring 703 is fixedly connected to the top of the inner wall of the movable groove 702. The spring 703 hangs vertically along the length of the movable groove 702. A movable frame 704 is fixedly connected to the end of the spring 703. A pressing member 705 is fixedly connected to the bottom of the movable frame 704. The outer wall of the movable frame 704 slides in fit with the inner wall of the movable groove 702. The movable frame 704 slides back and forth vertically along the inner wall of the movable groove 702. After the spring 703 deforms, it provides a downward elastic restoring force to the movable frame 704.

[0036] The bottom of the pressing part 705 is provided with an arc-shaped surface, which protrudes towards the anti-slip pad 5. The arc-shaped surface conforms to the outer surface contour of the electronic device. The arc-shaped surface is provided with a rubber layer, which increases the coefficient of friction between the bottom of the pressing part 705 and the surface of the electronic device. The rubber layer prevents the pressing part 705 from rigidly contacting and scratching the surface of the electronic device.

[0037] Working principle: In actual operation, the operator moves the pressing component 705 upward, which drives the movable frame 704 to slide upward inside the movable groove 702. The movable frame 704 compresses the spring 703 upward, causing it to contract and store force. The operator places the electronic device on the upper surface of the anti-slip mat 5. The operator releases the pressing component 705, and the spring 703 releases its elastic restoring force, pushing the movable frame 704 downward. The arc-shaped surface at the bottom of the pressing component 705 contacts the outer surface of the electronic device downward. The rubber layer on the arc-shaped surface generates friction with the electronic device, and the pressing component 705 restricts the electronic device on the anti-slip mat 5.

[0038] When the electronic device is placed on the surface of the anti-slip mat 5 to receive charging from the wireless charging device 3, the fan 605 starts to rotate. The fan 605 generates negative pressure inside the mounting component 601. Outside air is drawn into the mounting component 601 through the ventilation groove 4 and the air inlet 602. When the air flows through the cooling component 608, it exchanges heat with the internal cold water, and the air temperature drops to form cold air. The cold air continues to flow and comes into contact with the inclined guide plate 603. The guide plate 603 changes the direction of the cold air flow, and the cold air is guided to the upper area of ​​the anti-slip mat 5. The cold air flows between the protrusions on the surface of the anti-slip mat 5 and carries away the heat generated by the bottom of the electronic device.

[0039] Finally, it should be noted that the above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
