Background Technology
[0002] Several new energy vehicle models on the market now feature concealed door handles. Vehicles with concealed door handles tend to have a more streamlined appearance. However, in extreme cold weather, the door handles can easily become trapped by ice and snow inside the door, preventing occupants from starting the vehicle.
[0003] While some vehicles can use electric heating to melt the ice and snow around the handlebars, and then the handlebar motor drives the handlebars to extend, this method is inefficient, consumes more energy, and is prone to damaging the motor in situations with thicker ice layers.

This method utilizes the difference in thermal expansion coefficients of bimetallic strips to generate auxiliary thrust while heating, using the heating process to counteract the low ambient temperature, automatically adjusting the thrust, making full use of electrical energy reserves, and accelerating the unblocking efficiency.

[0059] This application uses a bimetallic strip structure for the thawing of car door handles.

[0074] The technical solution of the present invention will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. 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.
[0075] Figure 1 This is a flowchart of a method for unfreezing a vehicle's concealed door handle, provided by one or more embodiments of the present invention.
[0076] like Figure 1 The methods for unfreezing the vehicle's concealed door handle 2 shown include:
[0077] Step S1: Receive the instruction to extend handle 2;
[0078] Step S2: Based on the received instruction to extend handle 2, determine whether handle 2 is retracted within handle concealment area 1;
[0079] Step S3: If the handle 2 is retracted into the handle concealment area 1, then determine whether there is a low-temperature frozen substance 4 between the handle 2 and the handle concealment area 1.
[0080] Step S4: If there is a low-temperature frozen object 4, then handle 2 is frozen and the ice-breaking step is initiated.
[0081] Step S5: Determine whether the ice-breaking process is complete;
[0082] Step S6: If the ice-breaking step is completed, then execute the instruction to extend handle 2.
[0083] Step S7, wherein the ice-breaking step includes melting and / or breaking the cryogenic frozen material 4 between the handle 2 and the handle concealment area 1 and simultaneously pushing the handle 2 out of the handle concealment area 1.
[0084] Specifically, the cryogenic frozen material 4 typically refers to ice that condenses on the vehicle surface due to low temperatures. When the handle 2 is retracted (or concealed) within the handle concealment area 1, it is covered by ice and snow and frozen due to the influence of the external low temperature environment, preventing it from being easily extended. For example, if the driver uses the car key to transmit a radio frequency signal to control the handle 2 to extend, it will be blocked by the cryogenic frozen material 4. In this embodiment, if the vehicle receives a command to extend the handle 2, it first determines whether there is cryogenic frozen material 4 above the handle 2 and between the handle 2 and the handle concealment area 1. This can be achieved by using a motor that drives the handle 2 to sense whether the motor rotates smoothly, or by setting a current sensor to sense that the current increases when the motor stalls, indicating that the handle 2 is blocked by cryogenic frozen material 4. Alternatively, a temperature sensor can be used to determine the surrounding low temperature environment, which, in conjunction with the sensor that determines the motor rotation, confirms that the handle 2 is blocked by cryogenic frozen material 4 and trapped in the handle concealment area 1.
[0085] In this embodiment, the ice-breaking step involves simultaneously breaking and / or melting the low-temperature frozen material 4 between the handle 2 and the handle concealment area 1, and simultaneously pushing the handle 2 out of the handle concealment area 1. That is, as the temperature rises, the force pushing the handle 2 out of the handle concealment area 1 also increases. Typically, ice adhering to the vehicle surface weakens its adhesion after being locally heated. By applying a certain force simultaneously, the handle 2 is pushed out of the handle concealment area 1 without the low-temperature frozen material 4 being completely melted.
[0086] In this embodiment, melting and / or breaking the cryogenic frozen material 4 between the handle 2 and the handle concealment area 1, and simultaneously pushing the handle 2 out of the handle concealment area 1, includes:
[0087] A thermal expansion module 3 is installed between the handle 2 and the handle concealment area 1;
[0088] According to the ice-breaking procedure, the power supply drives the thermal expansion module 3 to melt and / or break the low-temperature frozen material 4 between the handle 2 and the handle concealment area 1, and simultaneously pushes the handle 2 out of the handle concealment area 1 and protrudes out.
[0089] Among them, the power supply drives the thermal expansion module 3 to heat the low-temperature frozen material 4, and the thermal expansion module 3 expands and deforms as the temperature of the thermal expansion module 3 rises.
[0090] Based on the expansion and deformation of the thermal expansion module 3, the handle 2 is pushed out of the handle concealment area 1 and protrudes.
[0091] Specifically, the gap between handle 2 and handle concealment area 1 is narrow, allowing water vapor to condense and seep in, forming part of the cryogenic material 4 in a low-temperature environment, thus bonding handle 2 to the inner wall of handle concealment area 1. The frozen "ice shell" on the surface of handle 2 and handle concealment area 1 prevents handle 2 from protruding, forming another part of the cryogenic material 4 that prevents handle 2 from protruding from the opening of handle concealment area 1. A thermal expansion module 3 is installed at a location selected in the gap between handle concealment area 1 and handle 2 (e.g., the thermal expansion module 3 is installed on the inner wall of handle concealment area 1 and at the edge of the opening of handle concealment area 1). The expansion module 3 is driven by a power source to heat and expand. Activating the power source drives the thermal expansion module 3 to heat the cryogenic material 4, and the expansion deformation caused by the temperature increase of the thermal expansion module 3 pushes handle 2 out of handle concealment area 1 from the inner wall of handle concealment area 1.
[0092] Figure 3 This is a schematic diagram of a vehicle concealed door handle unfreezing system provided in one or more embodiments of the present invention.
[0093] like Figure 3 The vehicle concealed door handle 2 unfreezing system shown includes: handle concealment area 1, handle 2, and thermal expansion module 3;
[0094] Handle concealment area 1 is set on the car door to conceal handle 2;
[0095] After the handle 2 extends out of the handle concealment area 1, it is used to open the car door;
[0096] The thermal expansion module 3 is located between the handle 2 and the handle concealment area 1. It is used to melt or / and break the low-temperature frozen material 4 between the handle 2 and the handle concealment area 1 and simultaneously push the handle 2 out of the handle concealment area 1.
[0097] The inner surface of the handle concealment area 1 is a funnel-shaped recessed area;
[0098] The outer surface of handle 2 is a frustum-shaped cube;
[0099] The handle 2 is concealed in the handle concealment area 1, and the outer surface of the handle 2 fits the inner surface of the handle concealment area 1;
[0100] Among them, the thermal expansion module 3 is installed on the inner wall of the handle concealment area 1 and at the edge of the opening in the handle concealment area 1;
[0101] The thermal expansion module 3 is externally wrapped with a soft thermally conductive shell 6.
[0102] Specifically, the handle 2 is a truncated cone cube, and the handle concealment area 1 is a funnel-shaped recessed area. The inner contour of the handle concealment area 1 matches the outer contour of the handle 2. The thermal expansion module 3 is disposed on the inner wall of the handle concealment area 1. While heating the cryogenic frozen material 4 to reduce the degree of adhesion, the thermal expansion module 3 can provide a thrust to push the handle 2 out of the handle concealment area 1 through expansion and compression.
[0103] Figure 4 This is a schematic diagram of the thermal expansion module structure of a vehicle concealed door handle unfreezing system provided in one or more embodiments of the present invention.
[0104] like Figure 4 The thermal expansion module 3 shown includes: thermal deformation module 8, support bushing 7, support slide rod 5, spring 9, and power supply;
[0105] The support rod 5 passes through the support bushing 7 and / or the spring 9;
[0106] Springs 9 are located at both ends of the support slide rod 5, multiple support bushings 7 are located in the middle of the support slide rod 5, and spaced thermal deformation modules 8;
[0107] The thermal deformation modules 8 are connected in series by the support slide rods 5 and are located inside the soft heat-conducting shell 6;
[0108] The heat deformation module 8 has support ends at both ends, and the support ends of the heat deformation module 8 are supported by adjacent support bushings 7.
[0109] The heat deformation module 8 has electrical electrodes 10 at both ends;
[0110] The positive and negative terminals of the power supply are electrically connected to the electrode terminals 10 of the thermal deformation module 8 via wire 17.
[0111] Specifically, multiple heat-deformation modules 8 are connected in series via support rods 5 and enclosed within a soft, heat-conducting shell 6. The soft, heat-conducting shell 6 assists in the interaction of heat between the heat-deformation modules 8 and the cryogenically frozen material 4, and withstands the expansion and deformation of the heat-deformation modules 8, thus pushing the handle 2. The heat-deformation modules 8 are spaced apart by support bushings 7 to prevent collisions and compression. Springs 9 are located at both ends or corners of the soft, heat-conducting shell 6 to buffer the spatial changes caused by deformation. Each heat-deformation module 8 has support ends at both ends that contact the support bushings 7, and electrical terminals 10 at both ends. The electrical terminals 10 connect the internal circuitry of the heat-deformation modules 8 in series, forming an electrothermal circuit that drives the heat-deformation modules 8 to heat up and expand.
[0112] Figure 5 This is a schematic diagram of the thermal deformation module structure of a vehicle concealed door handle unfreezing system provided in one or more embodiments of the present invention. Figure 1 .
[0113] like Figure 5The heat deformation module 8 shown includes: a first metal sheet 15, a second metal sheet 16, a fixing connector 13, and an elastic bladder 12;
[0114] The elastic bladder 12 is provided with electrical terminals 10 and support ends at both ends;
[0115] Inside the elastic bladder 12, a first metal sheet 15 and a second metal sheet 16 are arranged in parallel and fixed between two fixed connectors 13.
[0116] The fixed connector 13 connects the support ends of both ends of the elastic bladder 12;
[0117] The two ends of the first metal sheet 15 and / or the second metal sheet 16 are connected to the electrode terminals 10 at both ends of the heat deformation module 8 via wires 17.
[0118] The coefficient of thermal expansion of the first metal sheet 15 is not the same as that of the second metal sheet 16.
[0119] Specifically, one method for the thermal deformation module 8 to heat up and expand is to use a "bimetallic sheet" as both an electric heating component and a bimetallic sheet component. While heating with electric heating, the different thermal expansion coefficients of the bimetallic sheets cause bending and deformation, resulting in the expansion effect of the thermal deformation module 8.
[0120] The first metal sheet 15 and the second metal sheet 16 are a group, arranged in parallel and fixed between two fixed connectors 13 to form a bimetallic sheet component.
[0121] The wire 17 connects to the electrode terminals 10 at both ends of the heat deformation module 8, forming an electrothermal device unit. The first metal sheet 15 and the second metal sheet 16 can be used as electrothermal device units together, or they can be used as individual electrothermal device units. The elastic bladder 12 encloses the first metal sheet 15 and the second metal sheet 16 inside, using the external low temperature to suppress deformation and expansion. As the external low temperature environment continues to heat up, the bending deformation of the bimetallic structure of the first metal sheet 15 and the second metal sheet 16 intensifies.
[0122] Figure 6 This is a schematic diagram of the thermal deformation module structure of a vehicle concealed door handle unfreezing system provided in one or more embodiments of the present invention. Figure 2 .
[0123] Figure 7 This is a schematic diagram of the thermal deformation module structure of a vehicle concealed door handle unfreezing system provided in one or more embodiments of the present invention. Figure 3 .
[0124] Figure 8 This is a schematic diagram of the thermal deformation module structure of a vehicle concealed door handle unfreezing system provided in one or more embodiments of the present invention. Figure 4 .
[0125] In this embodiment, the thermal deformation module 8 includes: thermal expansion filler 14;
[0126] The elastic bladder 12 is filled with thermal expansion filler 14.
[0127] Specifically, the thermal expansion filler 14 can be a liquid, which expands the elastic bladder 12 by evaporation upon heating. Alternatively, the thermal expansion filler 14 can be a volatile solid, which expands the elastic bladder 12 by evaporation upon heating. Figure 6 As shown, the first metal sheet 15 serves as a heating element unit, heating the thermal expansion filler 14 to cause the elastic capsule 12 to expand. Figure 7 As shown, the bimetallic strip's bending deformation, combined with the volatilization of the thermal expansion filler 14, causes the elastic bladder 12 to expand. The thermal expansion filler 14 can uniformly expand the elastic bladder 12, while the bimetallic strip's bending deformation can push the important force application points; the two work together. Figure 8 The diagram shows another scheme where the bimetallic strip bends and deforms in conjunction with the volatilization of the thermal expansion filler 14, causing the elastic bladder 12 to expand. Only the first metal strip 15 is heated. By energizing only the first metal strip 15, the temperature difference between the first metal strip 15 and the second metal strip 16 is increased, allowing for a faster transition to the working state of bimetallic strip bending and deformation.
[0128] In this embodiment, it also includes:
[0129] The first metal sheet 15 and / or the second metal sheet 16 are heated by electric drive.
[0130] Specifically, the first metal sheet 15 and the second metal sheet 16 have superimposed electric heating and thermal deformation functions, which increases the difficulty of material selection. They can flexibly use the first metal sheet 15 or / and the second metal sheet 16 to drive heating based on specific technical reserves, material costs, and the functions they emphasize.
[0131] Figure 2 This is a structural diagram of a vehicle concealed door handle unfreezing device provided in one or more embodiments of the present invention.
[0132] like Figure 2 The vehicle concealed door handle 2 unfreezing device shown includes: a command receiving module, a shrinkage judgment module, a freeze judgment module, an ice breaking start module, an ice breaking judgment module, a command execution module, and a synchronous execution module;
[0133] The instruction receiving module is used to receive instructions for the handle 2 to extend.
[0134] The retraction judgment module is used to determine whether the handle 2 is retracted within the handle concealment area 1 based on the received instruction to extend the handle 2;
[0135] The freezing detection module is used to determine whether there is a low-temperature frozen substance 4 between the handle 2 and the handle concealment area 1 if the handle 2 is retracted into the handle concealment area 1.
[0136] The ice-breaking start module is used to initiate the ice-breaking process if there is a low-temperature frozen object 4, in which case the handle 2 is frozen.
[0137] The ice-breaking judgment module is used to determine whether the ice-breaking step has ended;
[0138] The instruction execution module is used to execute the instruction to extend handle 2 if the ice-breaking step is completed.
[0139] The synchronous execution module is used in which the ice-breaking step includes melting and / or breaking the cryogenic frozen material 4 between the handle 2 and the handle concealment area 1 and synchronously pushing the handle 2 out of the handle concealment area 1.
[0140] It is worth noting that although this system only discloses the instruction receiving module, shrinkage judgment module, freeze judgment module, icebreaking start module, icebreaking judgment module, instruction execution module, and synchronous execution module, the meaning of this invention is that, based on the above-mentioned basic functional modules, those skilled in the art can arbitrarily add one or more functional modules in combination with existing technology to form an infinite number of embodiments or technical solutions. In other words, this system is open rather than closed. The fact that this embodiment only discloses a few basic functional modules should not lead to the conclusion that the scope of protection of the claims of this invention is limited to the above-disclosed basic functional modules.
[0141] The above solution achieves the following beneficial technical effects:
[0142] This application uses a bimetallic strip structure for defrosting car door handles. On the one hand, the bimetallic strip is used as an electric heating component, and on the other hand, it is used as an expansion component. While heating the frozen material at low temperature, it also implements thrust drive, achieving two extrication functions with one unit of energy, thus increasing energy utilization.
[0143] This application uses a bimetallic strip structure for the thawing of car door handles. During the heating and deformation process of the bimetallic strip, the surrounding area inhibits the temperature rise, thus forming a function that simultaneously acts on the mechanical deformation and melting of the low-temperature frozen material to help the handle detach from the handle concealment area.
[0144] This application improves energy utilization by placing the thermal expansion module near the junction of the door handle and the handle concealment area, and quickly forms a channel for the handle to escape under the condition that the frozen material at low temperature is not completely melted.
[0145] This application increases the efficiency and reliability of the handle protruding from the handle concealment area by setting a cone-shaped cubic handle and a horn-shaped recessed handle concealment area.
[0146] This application utilizes a thermally expandable filler that expands upon heating. On one hand, it melts the cryogenically frozen material through external heat conduction, and on the other hand, it breaks up the cryogenically frozen material through thermal expansion. By using heat conduction to suppress excessive expansion, the breaking and fusing processes are carried out simultaneously.
[0147] In one specific embodiment, a circuit for controlling the current is also included. A switch may be provided on the handle 2, and the on / off state of the switch corresponds to the state in which the handle 2 is disengaged from the handle concealment area 1. The switch is used to control the power supply to the thermal resistor (e.g., the first metal piece 8 or the second metal piece 9). When the handle 2 is disengaged from the hand concealment area 1, the power supply to the thermal resistor is cut off. Alternatively, when the handle 2 is gripped, a command to cut off the power supply to the thermal resistor is generated. The state in which the handle 2 is disengaged from the hand concealment area 1 can be sensed by a position sensor to establish power supply to the thermal resistor.
[0148] Figure 9 This is a block diagram of an electronic device for an unfreezing method of a vehicle concealed door handle provided in one or more embodiments of the present invention.
