[0003] However, hidden external handles have the problem of freezing in winter conditions, that is, ice forms on the external handles, making it impossible to open the handles. This pain point has also become one of the main concerns of consumers about hidden external handles. At present, there is no effective solution to break the ice and open the handles under icy conditions. It mainly depends on the customer's own response. For example, it is stated in the after-sales manual that under icy conditions, customers are expected to use external force to remove the ice so that the handles can pop out, but this brings great inconvenience and insecurity to customers. Summary of the invention

[0018] Furthermore, before responding to the rewind icebreaking instruction, the method further includes:

[0019] In response to a handle opening instruction, executing a handle opening operation, controlling the handle to rotate from the initial position to the extended position;

[0020] If the handle is not extended within a third preset time threshold, and the number of times the handle opening operation is performed is greater than or equal to a preset number threshold, obtaining the current ambient temperature;

[0021] If the current ambient temperature is lower than the preset temperature threshold, a conventional ice-breaking operation is performed;

[0022] If the handle is still not extended after the conventional ice-breaking operation is completed, a retreat ice-breaking instruction is issued.

[0023] Furthermore, the conventional ice-breaking operation includes:

[0024] Controlling the handle to rotate from the initial position toward the extended position, and controlling the handle to rotate toward the initial position after maintaining the handle for a preset holding time;

[0060] Hidden external handle ice breaking method:

[0061] In the present application embodiment, Figure 1-3 As shown, the hidden external handle includes a base 01 and a handle 02 rotatably mounted in the base 01 , a receiving space 11 is provided on the base 01 , and the handle 02 is mounted in the receiving space 11 ;

[0062] The handle 02 is able to rotate at least between an extended position, an initial position and a retracted position. When the handle 02 is in the extended position, the handle 02 extends out of the base 01. When the handle 02 is in the initial position, the surface of the handle 02 remains flush with the surface of the base 01. When the handle 02 is in the retracted position, the surface of the handle 02 is recessed relative to the surface of the base 01 toward the receiving space 11.

[0063] Specifically, the surface of the base 01 is the outer surface of the vehicle door, the receiving space 11 is recessed inwardly on the surface of the base 01, the handle 02 is installed in the receiving space 11, and the handle 02 is rotatably installed in the receiving space 11. The handle 02 can rotate between an extended position, an initial position, and a retracted position. Figure 1 In the initial position shown, the surface of the handle 02 is flush with the surface of the base 01. In this state, the wind resistance at the handle 02 is small, and the handle 02 is in the initial position during the driving process of the vehicle. Figure 2 When the handle 02 is in the retracted position shown, the surface of the handle 02 is concave inward relative to the surface of the base 01. When the handle 02 is frozen, the handle 02 is controlled to rotate to the retracted position, and the surface of the handle 02 is separated from the inner surface of the ice layer, and an ice-breaking cavity is formed between the handle 02 surface and the ice layer. At this time, the user can knock the ice layer from the outside toward the ice-breaking cavity to break the ice. Figure 3 In the extended position shown, the handle 02 at least partially extends out of the receiving space 11, and the user can grasp the handle 02 to open the door.

[0064] The handle 02 can be rotated by a motor drive. When the handle 02 is in the initial position, the motor can be controlled to rotate forward to drive the handle 02 to rotate to the extended position, or the motor can be controlled to rotate reversely to drive the handle 02 to rotate to the retracted position. Naturally, when the handle 02 is in the retracted position, the motor can also be controlled to rotate forward to drive the handle 02 to rotate to the initial position and then continue to rotate to the extended position, which is specifically set according to the working requirements of the handle 02.

[0065] The hidden outer handle ice breaking method of the embodiment of the present application is as follows: Figure 4 As shown, including:

[0066] Step S401: in response to the retreat ice-breaking instruction, the handle is controlled to rotate from the initial position to the retreat position, so that an ice-breaking hole is formed between the ice layer and the handle surface for the user to manually break the ice from the outside;

[0067] Step S402: If a handle opening instruction is received, the handle is controlled to rotate from the retracted position to the extended position.

[0068] Specifically, the user can issue a retract ice-breaking command through a device such as a car key, or the retract ice-breaking command can be automatically issued when a preset condition is triggered, for example, by detecting the ambient temperature, and automatically issuing a retract ice-breaking command when the ambient temperature is lower than a preset temperature threshold. When the handle controller receives the retract ice-breaking command, it controls the handle to rotate from the initial position to the retracted position, that is, controls the motor to reverse and drive the handle to rotate, so that an ice-breaking hole is formed between the ice layer and the handle. At this time, the user can knock on the ice layer from the outside toward the ice-breaking space to break the ice. The existence of the ice-breaking hole makes the ice layer more likely to break, which can improve the effectiveness of ice breaking. When the handle is rotated to the retracted position, an audible and visual indication can be issued to remind the user that a manual ice-breaking operation can be performed.

[0069] After manually breaking the ice, the user can issue a handle opening command through the car key or the button on the handle. When the handle controller receives the handle opening command, it controls the handle to rotate from the retracted position to the extended position, that is, it controls the motor to drive the handle to rotate to the initial position and then continue to rotate to the extended position. After that, the user can pull the handle to open the car door.

[0070] The hidden outer handle of the present application is provided with a retracted position. The handle can continue to rotate inward to the retracted position at the initial position, so that the handle surface is recessed inward relative to the outer surface of the door. When the outer handle is frozen, the handle is controlled to rotate to the retracted position to separate the handle surface from the ice layer, and an ice-breaking hole is formed between the two so that the user can break the ice layer from the outside to achieve the ice-breaking operation. After the ice-breaking is completed, the user can issue a handle opening command, and the handle rotates from the retracted position to the extended position, and the user can use the handle to open the door. This ice-breaking method can provide the user with ice-breaking conditions and improve the user's ice-breaking efficiency and ice-breaking success rate.

[0071] In one embodiment, the hidden external handle is further provided with a retraction detection switch, which is triggered when the handle is rotated to the retraction position;

[0072] Control the handle to rotate from the initial position to the retracted position, specifically including:

[0073] The handle is controlled to rotate from the initial position toward the retracted position until the rotation time exceeds a first preset time threshold, or the retracted detection switch is triggered, then it is determined that the handle has rotated to the retracted position, and the handle is controlled to stop rotating.

[0074] Specifically, the retraction detection switch can be arranged around any actuating member on the transmission path of the motor-driven handle rotation, and when the handle rotates to the retraction position, the actuating member triggers the retraction detection switch. When the handle controller detects that the retraction detection switch is triggered, it determines that the handle has rotated to the retraction position.

[0075] In the embodiment of the present application, when controlling the handle to rotate from the initial position to the retracted position, after controlling the motor to reverse, the motor rotation time is timed and the real-time state of the retract detection switch is detected. If the retract detection switch is triggered, it is determined that the handle has rotated to the retracted position; since the retract detection switch is used less frequently and may fail, when the motor rotation time exceeds the first preset time threshold, it is also determined that the handle has rotated to the retracted position, thereby avoiding continuous actuation of the motor; judging whether the handle has rotated to the retracted position by the retract detection switch and the motor rotation time, the position state of the handle can be detected more accurately.

[0076] In one embodiment, the hidden external handle is further provided with an opening detection switch and a closing detection switch, wherein the opening detection switch is triggered when the handle is rotated to the extended position, and the closing detection switch is triggered when the handle is rotated to the initial position;

[0077] Control the handle to rotate from the retracted position to the extended position, specifically including:

[0078] The handle is controlled to rotate from the initial position toward the extended position until the rotation time exceeds a second preset time threshold, or the closing detection switch and the opening detection switch are triggered in sequence, then it is determined that the handle has rotated to the extended position, and the handle is controlled to stop rotating.

[0079] Specifically, the opening detection switch and the closing detection switch can be set around any actuator on the transmission path of the motor-driven handle rotation. When the handle rotates to the extended position, the corresponding actuator triggers the opening detection switch. The handle controller detects that the opening detection switch is triggered, and then determines that the handle has been rotated to the extended position; when the handle is rotated to the initial position, the corresponding actuator triggers the closing detection switch. The handle controller detects that the closing detection switch is triggered, and then determines that the handle has been rotated to the initial position.

[0080] See also Figure 1-Figure 3 , the handle rotates from the withdrawn position to the extended position, and it needs to rotate from the withdrawn position to the initial position first, and then rotate from the initial position to the extended position. Therefore, when controlling the handle to rotate from the withdrawn position to the extended position, the embodiment of the present application monitors the status of the closing detection switch and the opening detection switch. When the closing detection switch and the opening detection switch are triggered in sequence, it is determined that the handle has rotated to the extended position, and the motor is controlled to stop driving the handle to rotate. In addition, in order to determine that the handle has rotated to the full position when the closing detection switch and the opening detection switch fail, after controlling the motor to rotate forward, the motor rotation time is timed. If the motor rotation time exceeds the second preset time threshold, it is determined that the handle has rotated to the extended position.

[0081] The embodiment of the present application determines whether the handle is rotated from the retracted position to the extended position by detecting the motor rotation time and the status of the closed detection switch and the open detection switch, thereby more accurately detecting the position status of the handle rotation.

[0082] In one embodiment, after controlling the handle to rotate from the initial position to the retracted position, the method further comprises:

[0083] If a retreat ice-breaking command is received, it is determined whether the number of executions of the retreat ice-breaking operation exceeds a preset threshold number of times. If so, the ice-breaking process is terminated, otherwise the handle is controlled to rotate from the initial position to the retreat position.

[0084] Specifically, after the handle is controlled to rotate from the initial position to the retracted position, if the ice-breaking fails, the retract ice-breaking command is issued again. The user can actively issue the retract ice-breaking command again after the ice-breaking fails, or the system can be set to actively issue the retract ice-breaking command if the handle is not received within a set time after the handle is rotated to the retracted position. When the retract ice-breaking command is received, the number of consecutive executions of the retract ice-breaking operation is obtained. If the number of executions is less than the preset number threshold, the handle is controlled to rotate from the initial position to the retracted position again. If the handle is already in the retracted position, it will not be repeated; if the number of executions is greater than or equal to the preset number threshold, it is considered that multiple ice-breaking is invalid. At this time, the ice-breaking process is terminated and the retract ice-breaking command is no longer responded.

[0085] The embodiment of the present application can issue a fallback ice-breaking instruction again after the user fails to manually break the ice, and end the ice-breaking process when the number of executions of the fallback ice-breaking operation exceeds a preset number threshold.

[0086] In one of the embodiments, before responding to the fallback ice-breaking instruction, the method further includes:

[0087] In response to the handle opening instruction, the handle opening operation is performed to control the handle to rotate from the initial position to the extended position;

[0088] If the handle is not extended within the third preset time threshold, and the number of times the handle opening operation is performed is greater than or equal to the preset number threshold, then obtaining the current ambient temperature;

[0089] If the current ambient temperature is lower than the preset temperature threshold, the conventional ice-breaking operation is performed;

[0090] If the handle is not extended after the conventional ice-breaking operation is completed, a retreat ice-breaking command is issued.

[0091] Specifically, when using the car, the user first issues a handle opening command through the car key, handle button or other device. At this time, in response to the handle opening command, the motor is controlled to rotate forward to drive the handle from the initial position to the extended position; then the handle is detected to see whether it is extended, which can be detected by detecting whether the opening detection switch is triggered. If the handle is not extended within the third preset time threshold, the number of executions of the handle opening operation is obtained. If the number of executions is less than the preset number threshold, the handle is controlled to rotate from the initial position to the extended position again. If the number of executions is greater than or equal to the preset number threshold, it is considered that the handle is faulty or frozen at this time. At this time, the current ambient temperature is obtained. If the current ambient temperature is less than the preset temperature threshold, it is determined that the handle is frozen, and a conventional ice-breaking operation is performed. The conventional ice-breaking operation can be a heating and ice-melting operation or a large torque stall ice-breaking operation; if the handle is still not extended after the conventional ice-breaking operation is executed, a retract ice-breaking command is issued.

[0092] In the embodiment of the present application, after the handle opening operation is executed more than a preset number of times, it is determined through the current ambient temperature that the handle is frozen, and a conventional ice-breaking operation is performed to break the ice. After the ice-breaking fails, a retract ice-breaking instruction is issued. After the conventional ice-breaking operation, the ice layer on the surface of the handle will melt to a certain extent. At this time, the retract ice-breaking operation is performed, and the handle can be rotated to the retracted position more smoothly.

[0093] In one embodiment, the conventional ice breaking operation includes:

[0094] The handle is controlled to rotate from the initial position toward the extended position, and after maintaining the preset holding time, the handle is controlled to rotate toward the initial position;

[0095] After the above steps are performed continuously for a first preset number of times, it is determined whether the handle is extended.

[0096] The conventional ice-breaking operation in the embodiment of the present application is to repeatedly control the handle to extend toward the ice layer, and apply a pushing force to the ice layer at set intervals to achieve knocking and breaking of the ice.

[0097] Specifically, the motor is controlled to rotate in the forward direction, and after being locked for a set time, the motor is controlled to rotate in the reverse direction and retract, and this cycle is performed for a first preset number of times. If the handle is still not extended, a subsequent ice-breaking operation is performed.

[0098] Preferably, in conventional ice-breaking operation, when controlling the motor to rotate, a maximum voltage of 16V may be supplied to the motor to increase the motor torque and provide the handle with the greatest ice-breaking force.

[0099] In one of the embodiments, a heating element is also installed in the handle;

[0100] Conventional icebreaking operations also include:

[0101] The handle is controlled to rotate from the initial position toward the extended position, and after maintaining the preset holding time, the handle is controlled to rotate toward the initial position;

[0102] The above steps are continuously performed for a second preset number of times, while the heating element is controlled to heat and melt the ice, and then it is determined whether the handle is extended.

[0103] Specifically, the heating element can be a heating coil, which is installed inside the handle and can be coiled along the surface of the handle to increase the heating area of ​​the handle surface. The conventional ice-breaking operation also includes repeatedly controlling the handle to extend toward the ice layer, applying a pushing force to the ice layer at set intervals to achieve knocking and breaking ice, while energizing the heating element to control the heating element to heat and melt the ice, and performing both heating and knocking operations to further improve the ice-breaking efficiency. The specific execution method of the knocking ice-breaking operation can refer to the execution method of the knocking ice-breaking in the aforementioned embodiment, and the second preset number of times may be equal to or different from the first preset number of times.

[0104] Optionally, the conventional ice-breaking operation can first perform the knocking ice-breaking operation. If the handle cannot be extended after the first preset number of times, the knocking ice-breaking operation continues to be performed for a second preset number of times, and at the same time, the heating element is controlled to heat, and the heating ice-breaking operation is added simultaneously to improve the ice-breaking efficiency.

[0105] Figure 5 A flowchart of a hidden external handle ice-breaking method in a preferred embodiment of the present application is shown, specifically including:

[0106] Step S501: In response to a handle opening instruction, executing a handle opening operation, controlling the handle to rotate from an initial position to an extended position.

[0107] Step S502: If the handle is not extended within a third preset time threshold, and the number of times the handle opening operation is performed is greater than or equal to the preset number threshold, the current ambient temperature is obtained.

[0108] Step S503: If the current ambient temperature is lower than a preset temperature threshold, the handle is controlled to rotate from the initial position toward the extended position, and after a preset holding time, the handle is controlled to rotate toward the initial position.

[0109] Step S504: After the above steps are executed continuously for a first preset number of times, if the handle is not extended, the handle is controlled to rotate from the initial position toward the extended position, and after maintaining the preset holding time, the handle is controlled to rotate toward the initial position, and the heating element is controlled to heat and melt ice.

[0110] Step S505: Continuously execute the above steps for a second preset number of times, and if the handle is not extended, issue a retreat and ice-breaking command.

[0111] Step S506: In response to the retreat ice-breaking instruction, the handle is controlled to rotate from the initial position toward the retreat position until the rotation time exceeds the first preset time threshold, or the retreat detection switch is triggered, then the handle is judged to be rotated to the retreat position, and the handle is controlled to stop rotating, so that an ice-breaking hole is formed between the ice layer and the handle surface for the user to manually break the ice from the outside.

[0112] Step S507: If a handle opening instruction is received, execute step S508; if a retreat and ice-breaking instruction is received, execute step S509.

[0113] Step S508: Control the handle to rotate from the initial position toward the extended position until the rotation time exceeds the second preset time threshold, or the closing detection switch and the opening detection switch are triggered in sequence, then it is determined that the handle has rotated to the extended position, and the handle is controlled to stop rotating.

[0114] Step S509: determine whether the execution times of the retreat ice-breaking operation exceed the preset times threshold, if yes, end the ice-breaking process, otherwise control the handle to rotate from the initial position to the retreat position.

[0115] Hidden external handle structure:

[0116] The technical solution of the present application also provides a hidden external handle structure for executing the hidden external handle ice breaking method in the aforementioned embodiment, such as Figure 1-3 , 6, and 7, comprising a base 01 and a drive assembly and a handle mounted on the base 01;

[0117] The outer surface of the base 01 is provided with a receiving space 11, and the handle 02 is rotatably installed in the receiving space 11. The handle 02 can at least rotate between an extended position, an initial position and a retracted position. When the handle 02 is in the extended position, the handle 02 extends out of the base 01. When the handle 02 is in the initial position, the surface of the handle 02 is flush with the surface of the base 01. When the handle 02 is in the retracted position, the surface of the handle 02 is concave relative to the surface of the base 01 toward the receiving space 11.

[0118] The driving assembly is installed on the inner side of the base 01 , and the driving assembly is connected to the handle 02 to drive the handle 02 to rotate between the extended position, the initial position and the retracted position.

[0119] Specifically, if Figure 6 , 7 As shown, the base 01 is installed on the vehicle door, the receiving space 11 faces the outer surface of the vehicle door, the driving assembly is installed on the inner side of the base 01, and the handle 02 is installed in the receiving space and at least partially extends into the inner side of the base 01 to connect with the driving assembly. The driving assembly is actuated to drive the handle to rotate so that the handle can be moved as shown in FIG. Figure 1 The initial position shown, Figure 2 The retracement positions shown and Figure 3 The cam can be rotated between the extended positions shown.

[0120] In the embodiment of the present application, in order to enable the handle 02 to rotate to the retracted position, the accommodating space of the base is set to have a deeper depth compared to the existing structure, so that the handle 02 can be further rotated to the retracted position after being rotated to the initial position, so that an ice-breaking hole is formed between the surface of the handle 02 and the ice layer for the user to manually break the ice from the outside.

[0121] In one embodiment, if Figure 6 , 7 As shown, the driving device includes a driving motor 03, a push rod 04, and a rocker arm 05 rotatably mounted on a base 01;

[0122] One end of the push rod 04 is connected to the output shaft of the driving motor 03, and the other end is connected to the rocker arm 05. The handle 02 is rotatably connected to the rocker arm 05. The driving motor 03 drives the push rod 04 to extend and retract, and the push rod 04 pushes the rocker arm 05 to rotate so that the rocker arm 05 drives the handle 02 to rotate between the extended position, the initial position and the retracted position.

[0123] Specifically, the output shaft of the driving motor 03 rotates to drive the push rod 04 to extend and retract, so that the push rod 04 drives the rocking arm 05 to rotate around its rotation axis. A limit slot 51 is provided in the rocking arm 05, and the handle 02 is rotatably installed in the receiving space through the rotation axis. The handle 02 is provided with a driving part 21, and the driving part 21 extends into the limit slot 51. When the rocking arm 05 rotates, the driving part 21 is driven to rotate through the limit slot 51, and the driving part 21 drives the handle 02 to rotate. When the driving motor 03 drives the output shaft to rotate in the forward direction, the driving push rod 04 is extended to push the rocking arm 05 to rotate forward, and the rocking arm 05 drives the driving part 21 to make the handle 02 extend outward, including the process of the handle 02 rotating from the retracted position to the initial position and from the initial position to the extended position. When the drive motor 03 drives the output shaft to rotate in the opposite direction, the drive push rod 04 retracts to push the rocker arm 05 to rotate backward, and the rocker arm 05 drives the drive part 21 to retract the handle 02 inward, including the process of the handle 02 rotating from the extended position to the initial position and from the initial position to the retracted position.

[0124] In one embodiment, if Figure 8As shown, a ball socket 52 is provided on the rocker arm 05 , in which a freely movable ball head 41 is installed, and the ball head 41 is connected to the push rod 04 through a steel wire rope 42 .

[0125] Specifically, the ball head 41 is confined in the ball socket 52 and can move freely in the ball socket 52. The ball head 41 is connected to the push rod 04 through the wire rope 42. When the push rod 04 is extended, the push rod 04 pushes the rocker arm 05 to rotate forward. When the push rod 04 is retracted, the push rod 04 pulls the ball head 41. Since the ball head 41 is confined in the ball socket 52, the ball head 41 will pull the rocker arm 05 to rotate backward.

[0126] In the embodiment of the present application, the rocker arm 05 and the push rod 04 are connected by the cooperation of the ball socket 52 and the ball head 41, so that the extension and retraction of the push rod 04 can drive the rocker arm 05 to rotate forward and backward, so as to realize the rotation of the handle 02 from the initial position to the retracted position.

[0127] In one embodiment, if Fig. 9 As shown, a protruding trigger block 43 is provided on the side of the push rod 04, and a retraction detection switch 06 is provided on the outer side of the push rod 04. When the push rod 04 drives the handle 02 to rotate to the retraction position, the trigger block 43 triggers the retraction detection switch 06.

[0128] In the embodiment of the present application, a retraction detection switch 06 is provided on one side of the push rod 04. The retraction detection switch 06 can be a button switch. Specifically, a mounting seat 07 can be provided below the push rod 04, and the retraction detection switch 06 is mounted on the mounting seat 07. The retraction detection switch 06 is located at the position where the trigger block 43 is located when the handle 02 is in the retraction position. When the handle 02 is in the retraction position, the trigger block 43 presses the retraction detection switch 06 to trigger it.
