Description

Technical Field

[0001] The invention belongs to the technical field of automobile antifreeze, and in particular relates to a hidden outside handle ice-breaking device, an automobile and an ice-breaking method. Background Art

[0002] As the automotive industry accelerates its transformation toward electrification and intelligence, the exterior design of the entire vehicle tends to be more simple, smooth and futuristic. Hidden exterior handles are popular because they can reduce wind resistance and improve the overall aesthetics of the vehicle. However, this design faces severe challenges in extreme climate conditions, especially in low-temperature rain and snow in winter or in cold areas. The tiny gap between the hidden exterior handle and the door panel is prone to accumulate moisture and freeze quickly, making it difficult for users to open the door smoothly, which not only reduces the comfort of the user experience, but may also damage the handle or door structure due to forced operation, affecting the normal use and safety performance of the car.

[0003] In order to deal with this problem, a variety of innovative solutions have emerged in the industry, among which the handles with integrated graphene electric heating function are particularly eye-catching. This design cleverly embeds the flexible graphene electric heating film component into the handle structure. Specifically, the armrest cover component is designed to have a hollow chamber structure, with a skeleton installed inside to enhance the structural strength, and the graphene electric heating film is cleverly laid between the skeleton and the armrest cover component, and the outermost layer is covered with the armrest surface skin, forming a heating system that is both beautiful and practical. With its excellent electrical and thermal conductivity, graphene can quickly generate uniform heat at low voltage and effectively melt ice and snow.

[0004] In addition, another technical approach is to integrate the heating coil directly into the inner side of the handle cover of the hidden door handle, and select modified plastic materials with high thermal conductivity to make the handle cover and possible covers (such as the power supply port cover) to ensure that heat is quickly and evenly transferred to the surface. This type of heating coil is mostly a PTC (Positive Temperature Coefficient) electric heating coil, which is connected to the in-vehicle controller through an intelligent control system to achieve precise temperature regulation and energy consumption management.

[0005] However, it is worth noting that although these heating technologies significantly improve the performance of hidden exterior handles in cold weather, these methods that directly use heating coils still have the risk of burns when operated at high temperatures. At the same time, high-temperature heating coils can cause thermal damage to sheet metal and paint near the door handles. Summary of the invention

[0006] The purpose of the present invention is to provide a hidden external handle ice-breaking device, a car and an ice-breaking method to solve the problem that there is still a risk of burns when operating at high temperatures when directly using a heating coil, and the high-temperature heating coil will cause thermal damage to the sheet metal and car paint near the door handle.

[0007] To achieve the above object, the present invention adopts the following technical solutions:

[0008] In a first aspect, the present invention provides a hidden outside handle ice-breaking device, comprising a heating component, a ventilation component and a control unit; the heating component is installed on the inner side of the hidden outside handle, and the ventilation component is installed on the heating component, which is used to transfer the heat of the heating component to the inside of the outside handle through airflow, and the ventilation component and the heating component are connected to the control unit, and the control unit is used to control the operation of the heating component and the ventilation component.

[0009] Furthermore, the heating component is a heating coil, and the heating coil is arranged in an S shape.

[0010] Furthermore, a vent is provided on the inner side surface of the hidden outer handle, and the vent is connected to the internal movement mechanism of the hidden outer handle.

[0011] Furthermore, a heating coil holder is provided on the vent, and the heating coil is arranged in the heating coil holder.

[0012] Furthermore, the ventilation component is a fan, the fan covers the heating coil retaining frame, and the fan outlet faces the heating coil.

[0013] Furthermore, the control unit is a vehicle-mounted domain controller, which is used to send work instructions to the heating component and the ventilation component.

[0014] Furthermore, the vehicle-mounted domain controller is connected to the wireless communication module, and is connected to the remote client through the wireless communication module.

[0015] In a second aspect, the present invention provides a car, comprising the hidden outside handle ice-breaking device.

[0016] In a third aspect, the present invention provides an ice-breaking method for a hidden external handle ice-breaking device, comprising:

[0017] After receiving the instruction from the domain controller, the heating component starts to heat up, and the ventilation component drives the airflow. When the airflow passes through the heating coil, the airflow temperature rises, passes through the vents, enters the internal moving mechanisms of the outer handle, heats the internal moving mechanisms, and finally discharges through the gap between the door handle and the outer panel;

[0018] If there is ice on the inside and outside of the door handle, the hot air flow through the heating coil penetrates every corner of the handle, thus melting the ice.

[0019] Furthermore, the remote client controls the domain controller to issue instructions through APP operations.

[0020] Compared with the prior art, the present invention has the following technical effects:

[0021] The present invention uses the synergistic effect of a heating component (such as a heating coil) and a ventilation component (such as a fan) to quickly generate heat and effectively transfer it to the inside of the hidden exterior handle and the gap between it and the exterior door through airflow. The S-shaped arrangement of the heating coil helps to evenly distribute the heat, while the directional blowing of the fan enhances the convection effect of the heat, so that the ice and snow can be melted quickly, improving the ice-breaking efficiency.

[0022] The design of the present invention allows the selection of heating coils of different powers according to different environments and market demands. This flexibility enables automobile manufacturers to customize production according to the climatic conditions of different regions, ensuring that good ice-breaking effects can be achieved in different environments.

[0023] The heating coil and fan of the present invention do not directly contact the door outer panel, which effectively avoids the risk of damaging the door outer panel paint or scalding the user due to the overheating of the heating coil. At the same time, the introduction of the control unit (such as the vehicle-mounted domain controller) enables the heating and ventilation processes to be precisely adjusted through intelligent control, further improving the safety and reliability of the system.

[0024] The present invention integrates the heating component, ventilation component and control unit into the hidden outer handle, so that the device realizes a highly integrated design. In addition, the vehicle-mounted domain controller is connected to the wireless communication module, so that the user can remotely control the ice-breaking device through the remote client, which improves the convenience and intelligence level of use.

[0025] This technical solution effectively solves the problem of hidden exterior handles freezing in low-temperature environments, allowing users to easily open the door even in extreme weather conditions, significantly improving the user experience. At the same time, since the ice-breaking process is fast and safe, it reduces the risk of users damaging the vehicle due to forced operation.

[0026] In summary, this technical solution achieves efficient ice-breaking for hidden exterior handles through an innovative combination of heating and ventilation design, while taking into account safety, flexibility and intelligence, which is of great significance to improving the market competitiveness of automotive products.

Similarly, the phrases "if it is determined" or "if (stated condition or event) is detected" may be interpreted as "when it is determined" or "in response to determining" or "when detecting (stated condition or event)" or "in response to detecting (stated condition or event)", depending on the context.

[0040] Various structural schematic diagrams of the embodiments disclosed in the present invention are shown in the accompanying drawings. These figures are not drawn to scale, and some details are magnified and some details may be omitted for the purpose of clear expression. The shapes of various regions and layers shown in the figures and the relative sizes and positional relationships therebetween are only exemplary, and may deviate in practice due to manufacturing tolerances or technical limitations, and those skilled in the art may additionally design regions / layers with different shapes, sizes, and relative positions according to actual needs.

[0041] Example 1, please refer to Figure 3 The present invention provides a hidden outside handle ice-breaking device, including a heating component, a ventilation component and a control unit; the heating component is installed on the inner side of the hidden outside handle, the ventilation component is installed on the heating component, and is used to transfer the heat of the heating component to the inside of the outside handle through airflow, the ventilation component and the heating component are connected to the control unit, and the control unit is used to control the operation of the heating component and the ventilation component.

[0042] The present invention uses the synergistic effect of the heating component and the ventilation component to quickly generate heat and effectively transfer it to the inside of the hidden outer handle and the gap between it and the outer door through airflow. The S-shaped arrangement of the heating coil helps to evenly distribute the heat, while the directional blowing of the fan enhances the convection effect of the heat, so that the ice and snow can be melted quickly, improving the ice breaking efficiency.

[0043] Embodiment 2, the present invention provides a hidden external handle ice-breaking device, which specifically includes an external handle 1, a heating coil 3, a heating coil retaining frame 2, and a fan 4.

[0044] The heating coil, the heating coil holder and the fan are fixed to the rear end of the handle by screws, and a vent is provided at the rear end of the handle. The inner side of the hidden outer handle is provided with a vent, and the vent is connected to the internal movement mechanism of the hidden outer handle.

[0045] A heating coil holder 2 is arranged on the vent, and a heating coil 3 is arranged in the heating coil holder 2. The ventilation component is a fan 4, and the fan 4 covers the heating coil holder 2, and the fan outlet faces the heating coil 3.

[0046] After the heating component receives the instruction from the domain controller, the heating coil is heated to 260℃ within 1 minute. The fan drives the airflow. When the airflow passes through the heating coil, the airflow temperature rises, and then passes through the heating coil holder and the vents at the rear end of the handle, enters the various moving mechanisms inside the handle, and finally is discharged through the gap between the door handle and the outer panel.

[0047] The heating coil and fan of the present invention do not directly contact the door outer panel, which effectively avoids the risk of damaging the door outer panel paint or scalding the user due to the overheating of the heating coil. At the same time, the introduction of the control unit (such as the vehicle-mounted domain controller) enables the heating and ventilation processes to be precisely adjusted through intelligent control, further improving the safety and reliability of the system.

[0048] The present invention integrates a heating component, a ventilation component and a control unit inside a hidden outer handle, so that the device achieves a highly integrated design.

[0049] Embodiment 3, based on Embodiment 2, the control unit in the present invention, namely the vehicle-mounted domain controller, plays a vital role. It is not only the central nervous system of the entire hidden external handle ice-breaking device, but also the core component for realizing intelligent control. The vehicle-mounted domain controller is carefully designed to efficiently and accurately manage the operation of the heating component and the ventilation component, and ensures that the ice-breaking process is fast and safe by sending precise working instructions to them.

[0050] To further enhance the user experience, the vehicle domain controller is cleverly integrated with a wireless communication module. This innovative design breaks the geographical restrictions of traditional automotive component operation, allowing users to remotely control the icebreaker without having to physically touch the vehicle. The wireless communication module is like a bridge that closely connects the vehicle domain controller with the remote client. Whether through a mobile phone APP, smart home system or other remote access platform, users can easily send instructions to achieve instant operation of the icebreaker.

[0051] Specifically, when the user needs to start the ice-breaking function, they only need to tap a few times on the remote client, and the relevant instructions will be quickly transmitted to the vehicle domain controller through the wireless communication network. After receiving the instructions, the controller will immediately parse and execute them, start the heating component and ventilation component, and start the ice-breaking process. Similarly, users can also check the progress of ice-breaking, adjust working parameters or terminate the ice-breaking operation at any time through the remote client, realizing full monitoring and flexible control.

[0052] This remote control function not only greatly improves the convenience of use, but also gives the ice-breaking device a higher level of intelligence. It allows users to maintain their vehicles at any time and any place according to their actual needs, and effectively deal with the problem of door handle icing that may occur under extreme weather conditions. At the same time, the remote control function also reflects the trend of modern automobile technology towards a more humanized and intelligent direction, bringing users a more comfortable and convenient car experience.

[0053] Embodiment 4, an ice-breaking method of a hidden external handle ice-breaking device, comprising:

[0054] After receiving the instruction from the domain controller, the heating component starts to heat up, and the ventilation component drives the airflow. When the airflow passes through the heating coil, the airflow temperature rises, passes through the vents, enters the internal moving mechanisms of the outer handle, heats the internal moving mechanisms, and finally discharges through the gap between the door handle and the outer panel;

[0055] If there is ice on the inside and outside of the door handle, the hot air flow through the heating coil penetrates every corner of the handle, thus melting the ice.

[0056] The remote client issues instructions to the control domain controller through APP operation.

[0057] The built-in heating component (such as a heating coil) is used to quickly heat up, and the ventilation component (such as a fan) is used to evenly transfer the hot air flow to the inside and every corner of the hidden outer handle. This method can quickly increase the temperature inside the handle, effectively melt the ice accumulated between the inside of the door handle and the outer panel, and achieve rapid ice breaking.

[0058] Since the heating and ventilation are carried out inside the handle, this avoids the damage to the paint or other parts that may be caused by heating the outside of the vehicle. At the same time, the uniform heating inside also reduces the potential damage to the mechanical structure caused by local overheating.

[0059] This method combines the vehicle-mounted domain controller and the wireless communication module, allowing users to control and monitor the ice-breaking process through a remote client (such as a mobile phone APP). This intelligent control method not only improves the convenience of use, but also allows users to flexibly adjust the intensity and time of heating and ventilation according to actual needs, thereby achieving the best ice-breaking effect.

[0060] Since heating and ventilation are controlled according to actual needs, unnecessary energy waste is avoided. At the same time, by accurately controlling the time and intensity of heating and ventilation, energy consumption can be further reduced, which is in line with the design concept of energy saving and environmental protection of modern automobiles.

[0061] In cold weather, car door handles are easily covered with ice and snow, causing inconvenience to drivers. This ice-breaking method can quickly solve this problem, improve the convenience and comfort of vehicle use, and thus improve the overall satisfaction of users.

[0062] In summary, the ice-breaking method of the hidden external handle ice-breaking device has multiple technical effects such as high efficiency, intelligence, energy saving, environmental protection and improved user experience.

[0063] Working principle of the present invention:

[0064] 1. Device composition and layout

[0065] Heating assembly: mainly composed of heating coils 3, which are arranged in an S shape on the inner side of the hidden outer handle to ensure that the heat can be evenly distributed and cover a larger area.

[0066] Ventilation assembly: includes a fan 4, which is mounted on the heating coil holder 2, with its air outlet facing the heating coil 3. The function of the fan is to drive the airflow, so that the airflow is heated when passing through the heating coil, and then enters the inside of the outer handle through the vent.

[0067] Control unit: usually a vehicle-mounted domain controller, responsible for receiving external instructions (such as instructions from a remote client) and controlling the working status of the heating component and the ventilation component.

[0068] 2. Workflow

[0069] Command reception: When the vehicle domain controller receives an ice-breaking command from a remote client (such as a mobile phone APP) or the vehicle's internal system, it begins to prepare to start the ice-breaking program.

[0070] Heating component starts: The on-board domain controller sends a work instruction to the heating component, and the heating coil starts to heat up and generate heat.

[0071] Ventilation component starts: At the same time, the vehicle domain controller also sends instructions to the ventilation component, and the fan starts working to drive the surrounding air to flow. This air is heated when passing through the heating coil and becomes hot air flow.

[0072] Thermal air flow transfer: The heated air flows through the vents into the interior of the hidden exterior handle, including its internal movement mechanism. These hot air flows not only heat the internal mechanical structure, but also discharge through the gap between the door handle and the exterior panel to heat the ice layer on the outside.

[0073] Ice Melting: If there is ice covering the inside or outside of the door handle, the airflow heated by the heating coil will pass through every corner of the handle, melting the ice. This process continues until the ice is completely melted or the preset ice-breaking effect is achieved.

[0074] 3. Intelligent control

[0075] Remote control: Through the wireless communication module connected to the vehicle domain controller, the user can send ice-breaking instructions through the remote client (such as a mobile phone APP) when away from the vehicle to achieve remote ice-breaking operations.

[0076] Intelligent adjustment: The on-board domain controller can also intelligently adjust the working intensity and duration of the heating and ventilation components according to the actual conditions of the vehicle (such as outside temperature, ice thickness, etc.) to achieve the best ice-breaking effect and save energy.

[0077] 4. Security and protection mechanisms

[0078] Temperature control: To prevent the heating coil from overheating and causing damage to vehicle components or causing safety hazards, the on-board domain controller will monitor the temperature of the heating coil in real time and automatically reduce the heating power or shut down the heating component when necessary.

[0079] Structural optimization: By rationally designing the layout of the heating coil holder and vents, and selecting high-temperature and corrosion-resistant materials to make related components, the stability and reliability of the device can be ensured during long-term use.

[0080] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
