[0050] ​​​Various specific embodiments of the present invention will be described below with reference to the accompanying drawings that form a part of this specification. It should be understood that although directional terms such as "front", "rear", "up", "down", "left", "right", etc. are used in the present invention to describe various example structural parts and elements of the present invention, these terms are used here for convenience of description only and are determined based on the example orientations shown in the accompanying drawings. Since the embodiments disclosed in the present invention can be set in different directions, these directional terms are only for illustration and should not be regarded as limiting. In the following figures, the same figure numbers are used for the same parts.

[0051] Figure 1A It is a stereoscopic view of the first perspective of the handle assembly of the first embodiment of the present application installed on the vehicle sheet metal. Figure 1B Yes Figure 1A A second perspective view of the handle assembly is shown mounted to the vehicle sheet metal. Figure 1C Yes Figure 1A Exploded view of the handle assembly and vehicle sheet metal shown. Figures 1A-1C As shown, the handle assembly is mounted on a vehicle sheet metal 102. The vehicle sheet metal 102 is provided with a sheet metal through hole 103 extending through the vehicle sheet metal 102 in the thickness direction. The handle assembly includes a handle 104 and a base 106. The base 106 defines a base cavity 107. The base cavity 107 is recessed inward from the right surface of the base 106 to accommodate the handle 104. The handle 104 can be accommodated in the base cavity 107 and move relative to the base 106. The handle 104 has a closed position and an open position. When the vehicle is in driving, the handle 104 is in the closed position. When the vehicle is parked, the handle 104 is in the open position. As an example, the handle 104 can move translationally relative to the base 106. As an example, the base 106 is provided on one side of the vehicle sheet metal 102. When the base 106 is in place on the vehicle sheet metal 102 and the handle 104 is in the closed position, the handle outer surface 105 of the generally planar handle 104 is generally flush with the outer surface 101 of the vehicle sheet metal 102. When the base 106 is in place on the vehicle sheet metal and the handle 104 is in the open position, the handle outer surface 105 of the handle 104 protrudes beyond the outer surface 101 of the vehicle sheet metal 102.

[0052] like Figure 1A As shown, when the handle 104 is in the closed position, there is an annular gap between the base 106 and the outer periphery of the handle 104 to form an air supply space 103. More specifically, as shown in FIG. Figure 1CAs shown, base 106 includes a peripheral wall 112 and a bottom wall 114. Peripheral wall 112 surrounds the outer periphery of handle 104, and bottom wall 114 is disposed inside handle 104. Base 106 is provided with an air supply channel, allowing air to enter air supply space 103 through the air supply channel. Air entering air supply space 103 prevents handle 104 from freezing.

[0053] Figure 2 Yes Figure 1A The handle assembly and vehicle sheet metal shown along Figure 1A A cross-sectional view of line AA in FIG. 1 shows an embodiment of the air supply channel. Figure 2 As shown, the bottom wall 114 of the base 106 is provided with an air supply channel 202. Specifically, the air supply channel 202 penetrates the bottom wall 114 along the thickness direction of the bottom wall 114. The air supply channel 202 is connected to the air supply space 103, so that gas can enter the air supply space 103 through the air supply channel 202.

[0054] Figure 2 A schematic diagram of a handle system including the various components of the handle assembly of the first embodiment is also shown. Figure 2 As shown, the handle system also includes a gas delivery device 204 and an antifreeze control unit 206. The gas delivery device 204 and the antifreeze control unit 206 are communicatively connected and configured to deliver gas into the air supply space 103. The antifreeze control unit 206 is configured to control the activation and deactivation of the gas delivery device 204. In one embodiment, the gas delivery device 204 is the air conditioning unit of the vehicle in which the handle assembly is located. In other words, the air conditioning unit that provides conditioned air to the vehicle also provides air to the air supply space 103. Furthermore, because the temperature of the air delivered by the air conditioning unit is adjustable, the gas delivery device 204 can provide air that is warmer than the ambient temperature, thereby preventing the handle 104 from freezing. In another embodiment, the gas delivery device 204 is an air pump independent of the air conditioning unit of the vehicle in which the handle assembly is located. The air pump can provide air at ambient temperature. The air flows through the air supply space 103 and is blown out of the vehicle's sheet metal, thereby preventing liquid from condensing on the surface of the handle 104 and freezing it. The gas delivery device 204 is configured to be activated continuously or at predetermined intervals (i.e., intermittently) to supply gas to the plenum space 103. As one embodiment, the predetermined interval is 10 seconds. That is, the gas delivery device 204 supplies gas to the plenum space 103 for 10 seconds, then stops for 10 seconds and then starts again.

[0055] like Figure 2The handle system further comprises a humidity sensor 212 and a temperature sensor 214. The humidity sensor 212 is communicatively connected to the anti-freezing control unit 206 and is configured to detect the air humidity at which the handle 104 is located. The temperature sensor 214 is communicatively connected to the anti-freezing control unit 206 and is configured to detect the air temperature at which the handle 104 is located. The humidity sensor 212 and the temperature sensor 214 are capable of sending the currently obtained air humidity and air temperature to the anti-freezing control unit 206. The anti-freezing control unit 206 is configured to determine whether the handle 104 will freeze according to the environmental information including the air humidity and the air temperature, so as to control the start and stop of the gas delivery device 204.

[0056] Figure 3 An exploded view of the handle assembly of the second embodiment of the present application installed on a vehicle panel. Figure 3 The handle assembly of the second embodiment shown is the same as Figure 1A The same parts of the handle assembly of the first embodiment shown are not described again, and the differences are as follows: Figure 3 The handle assembly of the second embodiment shown further comprises a flow guide component 302. The flow guide component 302 is generally frame-shaped and is configured to guide the gas blown out from the air supply channel 202. The flow guide component 302 is arranged in the base cavity 107, partially extends into the air supply space 103, and surrounds the outer periphery of the handle 104.

[0057] Figure 4A The handle assembly of the second embodiment shown is the same as Figure 3 The handle assembly of the second embodiment shown is the same as Figure 3 A partial perspective view of the flow guide component 302 shown along the B-B line, Figure 4B The handle assembly of the second embodiment shown is the same as Figure 3 The handle assembly of the second embodiment shown is the same as Figure 3 The handle assembly of the second embodiment shown is the same as Figures 4A-4BAs shown, the flow guide member 302 defines a flow guide cavity 402, and has an inlet 403, a first outlet 404 and a second outlet 406. The inlet 403, the first outlet 404 and the second outlet 406 are all in communication with the flow guide cavity 402. The first outlet 404 and the second outlet 406 are located in the air supply space 103. The inlet 403 is in communication with the air supply channel 202, and the first outlet 404 and the second outlet 406 are arranged towards the air supply space 103, so that the gas blown out from the air supply channel 202 can enter the air supply space 103 through the flow guide member 302. Specifically, the flow guide member 302 comprises an inner side frame 422, an inclined frame 424, a vertical frame 426 and an outer side frame 428. Each of the inner side frame 422, the inclined frame 424, the vertical frame 426 and the outer side frame 428 is generally rectangular frame-shaped. The inner side frame 422 and the outer side frame 428 are arranged in parallel, and the outer side frame 428 surrounds the inner side frame 422. Any edge frame of the inner side frame 422 and the outer side frame 428 is generally parallel to the handle outer surface 105 of the handle 104. The space enclosed by the inner side frame 422 is slightly larger than the size of the handle 104, so that the handle 104 can be accommodated in the space enclosed by the inner side frame 422. The inner side frame 422 and the outer side frame 428 are arranged in a spaced manner, thereby forming the inlet 403. The inlet 403 is in communication with the air supply channel 202, so that the gas can enter the flow guide cavity 402. The inclined frame 424 is arranged obliquely to the handle outer surface 105 of the handle 104, and is connected with the inner side frame 422. The inclined frame 424 forms a guide portion 412. The guide portion 412 is located in the air supply space 103, and is configured to guide the movement of the handle 104 relative to the base 106. Specifically, when the handle 104 moves from the open position towards the closed position, the handle 104 is translated relative to the base 106 to approach the base 106. During the movement, the edge of the handle 104 will contact the guide portion 412, thereby being guided by the guide portion 412 to move towards the base 106, and finally enter the space enclosed by the inner side frame 422 and be kept in place. The second outlet 406 is arranged on the guide portion 412, and surrounds the outer periphery of the handle 104. The air supply direction of the second outlet 406 is oblique to the handle outer surface 105 of the handle 104, and is configured so that when the handle 104 is located in the closed position, the gas blown out from the second outlet 406 can blow on the side wall 304 (see Fig. 4) of the handle 104 which is generally perpendicular to the handle outer surface 105. Figure 3 The vertical frame 426 is arranged generally perpendicularly to the handle outer surface 105 of the handle 104, and is connected with the outer side frame 428 and the inclined frame 424. The first outlet 404 is arranged on the vertical frame 426, and surrounds the outer periphery of the handle 104. The air supply direction of the first outlet 404 is perpendicular to the handle outer surface 105 of the handle 104, and is configured so that the gas blown out from the first outlet 404 can move generally perpendicularly to the handle outer surface 105.

[0058] It should be noted that although the flow guide member 302 of the present application is provided with the first outlet 404 and the second outlet 406, in other embodiments, the second outlet 406 can not be provided.

[0059] It should be noted that although the flow guide member 302 of the present application is provided with one first outlet 404 and one second outlet 406, and the first outlet 404 and the second outlet 406 are both annular long openings, in other embodiments, the flow guide member 302 can be provided with at least two first outlets 404 and at least two second outlets 406, the at least two first outlets 404 can be arranged at intervals to surround at least part of the outer circumference of the handle 104, and the at least two second outlets 406 can be arranged at intervals to surround at least part of the outer circumference of the handle 104.

[0060] It should be noted that although the flow guide member 302 of the present application is arranged in the air supply space 103 and surrounds the outer circumference of the handle 104, in other embodiments, the flow guide member 302 can be arranged in segments to surround part of the outer circumference of the handle 104 and partially extend into the air supply space 103, so that the outlets (for example, the first outlet 404 and the second outlet 406) are located in the air supply space 103.

[0061] Figure 5 FIG. 3 is a sectional view of the handle assembly of the third embodiment of the present application installed on the vehicle panel. Figure 5 The handle assembly of the third embodiment shown is the same as the handle assembly of the second embodiment shown Figure 3 The same parts of the handle assembly of the third embodiment shown as the handle assembly of the second embodiment shown will not be described, and the differences are as follows: Figure 5 The gas delivery device 204 of the handle assembly of the third embodiment shown is a gas pump independent of the air conditioning device of the vehicle, and the handle assembly further comprises a heating member 502. The heating member 502 is in communication connection with the anti-freezing control unit 206 and is configured to heat the gas so that the heated gas enters the air supply space 103.

[0062] Figure 6 FIG. 2 is a sectional view of the handle assembly of the second embodiment of the present application installed on the vehicle panel. Figure 5 FIG. 6 is a schematic internal structure diagram of the anti-freezing control unit 206 shown. As Figure 6As shown, the antifreeze control unit 206 includes a bus 601, a processor 602, an input device 603, an output device 604, and a memory 605 containing a control program 606. The various components of the antifreeze control unit 206, including the processor 602, input device 603, output device 604, and memory 605, are communicatively connected to the bus 601, enabling the processor 602 to control the operation of the input device 603, output device 604, and memory 605. Specifically, the memory 605 is used to store programs, instructions, and data, and the processor 602 reads programs, instructions, and data from the memory 605 and can write data to the memory 605. By executing the programs and instructions read from the memory 605, the processor 602 controls the operation of the input device 603 and output device 604. The input device 603 receives external signals and data via connections 612 and 614, including the air humidity of the handle 104 detected by the humidity sensor 212 and the air temperature of the handle 104 detected by the temperature sensor 214. The output device 604 sends control signals to the gas delivery device 204 and the heating component 502 through the connection lines 622 , 624 , thereby controlling the opening and closing of the gas delivery device 204 and the opening and closing of the heating component 502 .

[0063] In the embodiment of the present application, the Figure 7 The program of the flowchart shown in FIG is stored in the memory 605 of the antifreeze control unit 206. The antifreeze control unit 206 controls the gas delivery device 204 and the heating component 502 by executing the program stored in the antifreeze control unit 206 by the processor 602.

[0064] Figure 7 This is a step diagram of the antifreeze method for the handle in the third embodiment of the present application. Figure 7 As shown, in step 702, processor 602 obtains environmental information that determines whether ice will form. This environmental information includes the humidity of the air surrounding the handle, the forecast for rain or snow, and the temperature of the air surrounding the handle. In step 704, processor 602 determines whether the handle will freeze based on the environmental information. In step 706, if the environmental information determines that the handle will freeze, processor 602 controls air delivery device 204 and heating element 502 to supply air to the space surrounding the handle to prevent it from freezing.

[0065] Figures 8A-8B It is an application Figure 7 Flowchart of the handle antifreeze method shown in FIG. Figures 8A-8BAs shown, in step 802, the processor 602 acquires the detected air humidity at which the handle 104 is located from the humidity sensor 212, acquires the detected air temperature at which the handle 104 is located from the temperature sensor 214, and acquires the weather forecast from the network side. Then, the processor 602 proceeds to step 804.

[0066] In step 804, the processor 602 determines whether the air humidity at which the handle 104 is located is greater than a preset air humidity, or whether the weather forecast predicts rain or snow on the day. As an example, the preset air humidity is 80%. If the air humidity at which the handle 104 is located is less than or equal to the preset air humidity, or the weather forecast does not predict rain or snow on the day, the processor 602 proceeds to step 802. If the air humidity at which the handle 104 is located is greater than the preset air humidity, or the weather forecast predicts rain or snow on the day, the processor 602 proceeds to step 806.

[0067] In step 806, the processor 602 determines whether the air temperature at which the handle 104 is located is less than a prevention temperature. As an example, the prevention temperature is 0°C. In another example, the prevention temperature is -5°C. If the air temperature at which the handle 104 is located is greater than or equal to the prevention temperature, the processor 602 proceeds to step 802. If the air temperature at which the handle 104 is located is less than the prevention temperature, the processor 602 proceeds to step 802. Thus, by steps 804 and 806, the processor 602 determines whether the handle will be frozen. When the processor 602 determines that the handle will be frozen, the processor 602 proceeds to step 802.

[0068] In step 812, the processor 602 sends the start of the anti-freezing confirmation information to the user. As an example, the anti-freezing control unit 206 is communicatively connected to the user's mobile phone, and thus sends the anti-freezing confirmation information to the user's mobile phone for the user to confirm. Then, the processor 602 proceeds to step 814.

[0069] In step 814, the processor 602 waits for the user to confirm the start of the anti-freezing. When the user prevents the start of the anti-freezing, the processor 602 proceeds to step 802. When the user agrees to the start of the anti-freezing, the processor 602 proceeds to step 816. For one embodiment, when the user does not reject the start of the anti-freezing within a predetermined time, the processor 602 considers that the user agrees to the start of the anti-freezing, and the processor 602 controls the gas delivery device 204 to be turned on, thus delivering air to the space around the handle 104 (i.e., the air delivery space 103). When the user rejects the start of the anti-freezing within the predetermined time, the processor 602 considers that the user prevents the start of the anti-freezing. As an example, the predetermined time is 5 minutes.

[0070] In step 816, the processor 602 determines whether the air temperature at the handle is less than the freezing temperature. When the air temperature at the handle is greater than or equal to the freezing temperature, the processor 602 controls the gas delivery device 204 to be turned on, thereby sending normal temperature air (i.e., air having an ambient temperature) to the space around the outer periphery of the handle 104. Subsequently, the processor 602 transfers the operation to step 802. When the air temperature at the handle is less than the freezing temperature, the processor 602 sends hot air to the space around the outer periphery of the handle 104. In other words, the processor 602 controls the gas delivery device 204 and the heating member 502 to be turned on. Subsequently, the processor 602 transfers the operation to step 802. In one example, the freezing temperature is -10°C. In another example, the freezing temperature is -15°C. In another example, the freezing temperature is -25°C.

[0071] The handle system of the present application has a freeze prevention control unit that controls the supply of gas into the air supply space around the handle in accordance with environmental information that determines whether or not freezing will occur, thereby preventing the handle from freezing. The environmental information that determines whether or not freezing will occur includes weather forecasts, thereby increasing the likelihood that freezing of the handle will be predicted, so that freezing of the handle can be effectively prevented.

[0072] The handle assembly of the present application has an air supply passage provided in the base, thereby supplying air to the air supply space around the handle, so that liquid such as rainwater / dew does not enter the air supply space, thereby preventing the handle from freezing.
