Abstract
Description
Technical Field

[0002] In severe winter or freezing rain, vehicle door handles are prone to freezing due to melting snow or direct exposure to freezing rain. For most mechanical pull-out handles on the market, ice typically accumulates in the gap between the handle and the door panel, as well as around the mechanical linkage mechanism. The ice can "stick" the handle to the base or door panel, making it impossible for the user to pull it normally. In emergencies, users often try to break the ice by pulling or hitting it forcefully, which can easily lead to breakage of the handle's mechanical structure, damage to the paint, or breakage of internal plastic parts. Summary of the Invention

[0027] According to a first aspect of the present invention, a vehicle door is provided, comprising a door body and a handle 1. An ice-breaking component is disposed inside the handle 1. When ice forms on the handle 1, the state of the ice-breaking component can be controlled to break the ice at the handle 1 without damaging the vehicle body structure. In this embodiment, the door body and the handle 1 are correspondingly connected by a mechanical linkage assembly 4, i.e., the handle 1 is actually formed as a mechanical pull handle 1. The assembly method and operating principle of the mechanical pull handle 1 and the door body are both prior art; therefore, the specific structure of the mechanical linkage assembly 4 will not be described in detail.
[0028] In this embodiment, as Figure 1 As shown, the handle 1 has a receiving cavity, within which a partition divides the cavity into a first receiving cavity 21 and a second receiving cavity 22. The first receiving cavity 21 is located at the center of the handle 1 and covers the user's gripping area, while the second receiving cavity 22 is located at the first end of the handle 1. The aforementioned mechanical linkage assembly 4 is also located at the first end of the handle 1. Further, the ice-breaking assembly in this embodiment includes a heating module located in the first receiving cavity 21 and a vibration module located in the second receiving cavity 22. The heating module generates heat to melt the ice layer; the vibration module generates high-frequency mechanical vibration to output vibrational force to the entire handle 1, thereby using physical stress to break the ice layer. The heating module and the vibration module can be used independently or in combination.
[0029] More specifically, such as Figure 1 As shown, the heating module includes a heating film 31 fitted to the inner wall of the first receiving cavity 21. The specific location of the heating film is not fixed, but it needs to cover the user's gripping area and the gap between the handle 1 and the door body to facilitate the melting of ice. It should be noted that the heating film 31 itself is an existing component that can generate heat when energized. Correspondingly, the heating module also includes a temperature sensor 32 (in this embodiment, it is essentially formed as a thermistor corresponding to the heating film 31), which can monitor the heating temperature of the heating film 31 in real time to facilitate closed-loop control and overheat protection.
[0030] In addition, the vibration module in this embodiment includes a vibration motor 33 (which can be an eccentric rotary mass motor or a linear resonant actuator), which is located in the second receiving cavity 22. That is, the vibration motor 33 is set close to the mechanical linkage assembly 4, which can facilitate the breaking of the ice layer at the mechanical linkage assembly 4.
[0031] To better control the ice-breaking component, in this embodiment, a displacement sensor (such as a Hall sensor or a micro switch) is also provided at the mechanical linkage assembly 4. The displacement sensor can detect whether the handle 1 has undergone physical displacement. Specifically, when the ice-breaking component successfully breaks the ice layer, the displacement sensor can detect the corresponding displacement signal. When the user manually pulls the handle 1 and the displacement sensor does not detect the corresponding displacement signal, it indicates that the ice layer has not been broken.
[0032] In this embodiment, the ice-breaking component is started or stopped by a controller. The heating module and vibration module in the ice-breaking component are electrically connected to the controller. In addition, the displacement sensor is also electrically or communicatively connected to the controller. Preferably, the controller can be integrated with the vehicle's main control module.
[0033] According to the present invention, when ice forms on the door handle 1, the heating module and / or vibration module located inside the handle 1 can be activated by the controller to break the ice layer by heating and / or generating high-frequency mechanical vibration, thereby thawing the handle 1. This can effectively avoid problems such as mechanical structure breakage, paint damage, or brittle fracture of internal plastic parts of the handle 1.
[0034] According to a second aspect of the present invention, a vehicle is provided, the vehicle including the doors as described above, the vehicle further including a central control module, the controller being integrated with the central control module; furthermore, the vehicle includes a temperature probe for detecting ambient temperature, the temperature probe being electrically or communicatively connected to the controller.
[0035] According to a third aspect of the present invention, a method for breaking ice on a vehicle door is provided, which is applied to the vehicle described above, specifically, as follows: Figure 2 As shown, the method for breaking ice on the car door includes the following steps: S10: After receiving the unlock signal, when the temperature probe detects that the ambient temperature has reached the preset value, the main control module controls the heating module to start and puts the heating module into preheating state. The heating module is in a preheating state, and the actual heating film 31 is in a low-power heating mode, with a lower heating temperature.
[0036] S20: Manually pull the external handle 1. When the main control module receives the signal from the displacement sensor, the main control module controls the heating module to turn off; when the main control module does not receive the signal from the displacement sensor, the main control module controls the heating module to be in full heating state and controls the vibration module to start. The heating module is in a fully heated state, and the actual heating film 31 is in a high-power heating mode, with a high heating temperature.
[0037] S30: Manually pull the handle 1. When the main control module receives the signal from the displacement sensor, the main control module controls the heating module and vibration module to shut down; when the main control module does not receive the signal from the displacement sensor, the main control module issues an alarm signal.
[0038] Preferably, a timeout protection function can also be set in the main control module. That is, when the heating module and the vibration module work together, if the maximum set time is reached and the main control module does not receive a signal from the displacement sensor, the main control module can send an alarm message to the user through the vehicle network and forcibly shut down the ice-breaking component to prevent damage to components.
[0039] Finally, it should be noted that the above-described embodiments are merely specific implementations of this application, used to illustrate the technical solutions of this application, and not to limit them. The protection scope of this application is not limited thereto. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that any person skilled in the art can still modify or easily conceive of changes to the technical solutions described in the foregoing embodiments, or make equivalent substitutions for some of the technical features, within the technical scope disclosed in this application. Such modifications, changes, or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this application, and should all be covered within the protection scope of this application. Therefore, the protection scope of this application should be defined by the protection scope of the claims.
