Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of automobile outer handle, and in particular to a hidden outer handle ice breaking method and structure, a storage medium and an electronic device. BACKGROUND

[0002] With the fierce competition in the domestic automobile market and the increasing expectations of customers for appearance modeling, the hidden outer handle has been significantly improved in the vehicle model fitting rate, especially in EV models that emphasize technology and experience, because it not only has stronger technological sense and more simple and smooth side modeling, but also can significantly reduce the wind resistance of the vehicle during driving to save fuel consumption.

[0003] However, the hidden outer handle has a freezing problem in winter working conditions, that is, the handle cannot be opened due to ice accumulation on the handle. This pain point has become one of the main concerns of consumers for the hidden outer handle. There is currently no effective solution to the ice breaking and opening of the handle in the ice accumulation working condition. It still mainly depends on the customer to respond independently, such as indicating in the after-sales manual that the customer should use external force to remove the ice to pop out the handle in the ice accumulation working condition, but this brings great inconvenience and insecurity to the customer. SUMMARY

[0004] The purpose of the present application is to overcome the deficiency of no effective solution for handle ice accumulation in the prior art, and to provide a hidden outer handle ice breaking method and structure, a storage medium and an electronic device, which can effectively break ice when the hidden outer handle is frozen.

[0005] The technical solution of the present application provides a hidden outer handle ice breaking method, the hidden outer handle comprising a base and a handle rotatably installed in the base, the base being provided with a receiving space, and the handle being installed in the receiving space;

When the handle is in the retracted position, the surface of the handle is recessed relative to the surface of the base towards the receiving space;

[0007] The method comprises:

[0008] In response to a fallback ice breaking instruction, the handle is controlled to rotate from the initial position to the retracted position, so that an ice breaking cavity is formed between the ice layer and the surface of the handle for the user to manually break ice from the outside;

[0016] Further, after the control of the handle rotating from the initial position to the retraction position, it further includes:

[0017] If the back-breaking ice instruction is received, it is judged whether the execution frequency of the back-breaking ice operation exceeds the preset frequency threshold, if yes, the ice breaking process is ended, otherwise the handle is controlled to rotate from the initial position to the retraction position.

[0018] Further, before responding to the back-breaking ice instruction, it further includes:

[0019] In response to the handle opening instruction, the handle opening operation is executed, and the handle is controlled to rotate from the initial position to the extension position;

[0020] If the handle is not extended within the third preset time threshold, and the execution frequency of the handle opening operation is greater than or equal to the preset frequency threshold, the current environment temperature is obtained;

[0021] If the current environment temperature is less than the preset temperature threshold, the regular ice breaking operation is executed;

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

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

[0024] Control the handle to rotate from the initial position toward the extended position, maintain the position for a preset time, and then control the handle to rotate back to the initial position.

[0025] After performing the above steps for the first preset number of times, determine whether the handle has extended.

[0026] Furthermore, a heating element is also installed in the handle;

[0027] The standard ice-breaking procedure also includes:

[0028] Control the handle to rotate from the initial position toward the extended position, maintain the position for a preset time, and then control the handle to rotate back to the initial position.

[0029] The above steps are executed a second preset number of times, while the heating element is controlled to melt the ice, and then it is determined whether the handle extends.

[0030] The technical solution of this application also provides a concealed external handle structure for performing the concealed external handle ice-breaking method as described above, including a base and a drive component and handle mounted on the base;

[0031] The outer surface of the base is provided with a receiving space, and the handle is rotatably mounted in the receiving space. The handle can rotate at least between an extended position, an initial position, and a retracted position. When the handle is in the extended position, the handle extends out of the base. When the handle is in the initial position, the surface of the handle is flush with the surface of the base. When the handle is in the retracted position, the surface of the handle is recessed into the receiving space relative to the surface of the base.

[0033] Furthermore, the driving device includes a drive motor, a push rod, and a rocker arm rotatably mounted on the base;

[0034] One end of the push rod is connected to the output shaft of the drive motor, and the other end is connected to the rocker arm. The handle is rotatably connected to the rocker arm. The drive motor drives the push rod to extend and retract, and the push rod pushes the rocker arm to rotate so that the rocker arm drives the handle to rotate between the extended position, the initial position, and the retracted position.

[0035] Furthermore, the rocker arm is provided with a ball socket, and a freely movable ball head is installed in the ball socket. The ball head is connected to the push rod by a steel wire rope.

[0036] Furthermore, the push rod has a protruding trigger block on its side and a retraction detection switch on its outer side. When the push rod drives the handle to rotate to the retraction position, the trigger block triggers the retraction detection switch.

[0040] The memory stores instructions that can be executed by the at least one processor to enable the at least one processor to perform the previously described hidden external handle ice-breaking method.

[0041] The above technical solution has the following beneficial effects:

[0042] When the outer door handle is frozen, this application controls the handle to rotate to the retracted position, separating the handle surface from the ice layer and creating an ice-breaking cavity between them. This allows the user to break the ice from the outside. After ice breaking, the user can issue a command to open the handle, and the handle will rotate from the retracted position to the extended position, allowing the user to open the car door. This ice-breaking method provides users with the conditions for ice breaking, improving the efficiency and success rate of ice breaking. Attached Figure Description

[0056] The specific embodiments of this application will be further described below with reference to the accompanying drawings.

For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to mechanical connections or electrical connections; they can refer to direct connections or indirect connections through an intermediate medium; and they can refer to the internal connection between two components. Those skilled in the art can understand the specific meanings of the above in this application according to the specific circumstances.

[0060] Hidden external handle ice-breaking method:

[0061] In the embodiments of this application, such as Figures 1-3 As shown, the concealed external handle includes a base 01 and a handle 02 rotatably mounted in the base 01. The base 01 is provided with a receiving space 11, and the handle 02 is installed in the receiving space 11.

[0062] The handle 02 is able to rotate between at least the extended position, the initial position, and the 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 recessed into the receiving space 11 relative to the surface of the base 01.

[0063] Specifically, the surface of the base 01 is the outer surface of the car door, and the receiving space 11 is recessed inward on the surface of the base 01. The handle 02 is installed in the receiving space 11 and is rotatably installed within the receiving space 11. The handle 02 can rotate between an extended position, an initial position, and a retracted position. The handle 02 is in the position of... Figure 1 In the initial position shown, the surface of handle 02 is flush with the surface of base 01. In this state, the wind resistance at handle 02 is low, and handle 02 remains in its initial position during vehicle operation. Handle 02 is in the position shown... Figure 2 When the handle 02 is in the retracted position as shown, its surface is concave relative to the base 01. When ice forms on the surface of the handle 02, rotating the handle 02 to the retracted position separates the surface of the handle 02 from the inner surface of the ice layer, creating an ice-breaking cavity between the handle 02 surface and the ice layer. The user can then tap the ice layer from the outside towards this cavity to break the ice. Figure 3 When the handle 02 is in the extended position shown, it extends at least partially outside the receiving space 11, at which point the user can grab the handle 02 to open the door.

[0064] Handle 02 can be rotated by a motor. When handle 02 is in the initial position, the motor can be controlled to rotate forward to drive handle 02 to the extended position, or the motor can be controlled to rotate in reverse to drive handle 02 to the retracted position. Of course, when handle 02 is in the retracted position, the motor can also be controlled to rotate forward to drive handle 02 to rotate to the initial position and then continue to rotate to the extended position, depending on the working requirements of handle 02.

[0065] The concealed external handle ice-breaking method of this application embodiment, such as Figure 4 As shown, it includes:

[0066] Step S401: In response to the retraction ice-breaking command, control the handle to rotate from the initial position to the retraction 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 command is received, control the handle to rotate from the retracted position to the extended position.

[0068] Specifically, the system can be activated by the user via a car key or similar device, or automatically when preset conditions are met. For example, it can detect ambient temperature and activate the command when the ambient temperature is below a preset threshold. When the handle controller receives the command, it rotates the handle from its initial position to the retracted position, causing the motor to reverse and rotate the handle, creating an ice-breaking hole between the ice and the handle. The user can then tap the ice from the outside towards this hole to break it. The presence of the ice-breaking hole makes the ice easier to break, improving the effectiveness of the ice-breaking process. An audible and visual indicator can be activated when the handle is rotated to the retracted position to remind the user to perform manual ice-breaking.

[0069] After manually breaking the ice, the user can issue a handle opening command via 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 rotate forward to drive the handle to rotate to the initial position and then to the extended position. After that, the user can pull the handle to open the car door.

[0070] The concealed external door handle of this application has a retractable position. From its initial position, the handle can be rotated inwards to the retractable position, causing the handle surface to be recessed inwards relative to the exterior of the door. When the external door handle is iced over, controlling the handle to rotate to the retractable position separates the handle surface from the ice layer, creating an ice-breaking cavity between them. This allows the user to break the ice from the outside. After ice breaking, the user can issue an open command, and the handle will rotate from the retracted position to the extended position, allowing the user to open the door. This ice-breaking method provides users with the necessary conditions for ice breaking, improving efficiency and success rate.

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

[0072] Controlling the handle to rotate from the initial position to the retracted position includes:

[0073] The handle is controlled to rotate from the initial position toward the retracted position until the rotation time exceeds the 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 set around any actuator on the transmission path of the motor-driven handle rotation. When the handle rotates to the retraction position, the actuator triggers the retraction detection switch. The handle controller detects that the retraction detection switch has been triggered and determines that the handle has rotated to the retraction position.

[0075] In this embodiment, when controlling the handle to rotate from the initial position to the retracted position, the motor is reversed, and the rotation time of the motor is timed while the real-time status of the retracted detection switch is detected. If the retracted detection switch is triggered, it is determined that the handle has rotated to the retracted position. Since the retracted detection switch is used infrequently and may malfunction, it is also determined that the handle has rotated to the retracted position if the motor rotation time exceeds a first preset time threshold, thereby preventing the motor from continuously operating. By using the retracted detection switch and the motor rotation time to determine whether the handle has rotated to the retracted position, the position status of the handle can be detected more accurately.

[0076] In one embodiment, the concealed external handle is further provided with an on detection switch and an off detection switch. The on detection switch is triggered when the handle is rotated to the extended position, and the off detection switch is triggered when the handle is rotated to the initial position.

[0077] Controlling the handle to rotate from the retracted position to the extended position specifically includes:

[0078] 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 off detection switch and the on detection switch are triggered in sequence, then determine that the handle has rotated to the extended position and control the handle to stop rotating.

[0079] Specifically, the on and off detection switches 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 on detection switch. The handle controller detects that the on detection switch has been triggered and determines that the handle has rotated to the extended position. When the handle rotates to the initial position, the corresponding actuator triggers the off detection switch. The handle controller detects that the off detection switch has been triggered and determines that the handle has rotated to the initial position.

[0080] See Figures 1-3 For the handle to rotate from the retracted position to the extended position, it needs to first rotate from the retracted position to the initial position, and then from the initial position to the extended position. Therefore, in this embodiment, when controlling the handle to rotate from the retracted position to the extended position, the state of the closed and open detection switches is monitored. When the closed and open detection switches are triggered sequentially, 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 correct position even if the closed and open detection switches fail, the motor rotation time is timed after the motor is controlled to rotate forward. If the motor rotation time exceeds a second preset time threshold, it is determined that the handle has rotated to the extended position.

[0081] This application embodiment determines whether the handle has rotated from the retracted position to the extended position by measuring the motor rotation time and detecting the state of the detection switch being closed and open, thereby more accurately detecting the position 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 includes:

[0083] If a rewind ice-breaking command is received, it is determined whether the number of rewind ice-breaking operations has exceeded a preset threshold. If so, the ice-breaking process ends; otherwise, the handle is controlled to rotate from the initial position to the rewind position.

[0084] Specifically, after controlling the handle to rotate from the initial position to the retracted position, if icebreaking fails, a retraction icebreaking command is issued again. This can be done either by the user actively issuing the retraction icebreaking command after a failed attempt, or by the system automatically issuing the retraction icebreaking command if no handle-opening command is received within a set time after the handle has rotated to the retracted position. When a retraction icebreaking command is received, the number of consecutive executions of the retraction icebreaking operation is recorded. If the number of executions is less than a preset 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, the execution is not repeated. If the number of executions is greater than or equal to the preset threshold, the multiple icebreaking attempts are considered invalid, and the icebreaking process ends, with no further response to retraction icebreaking commands.

[0085] This embodiment of the application can issue a rollback ice-breaking command again after the user fails to manually break the ice. When the number of rollback ice-breaking operations exceeds a preset threshold, the ice-breaking process ends.

[0086] In one embodiment, prior to responding to the rollback ice-breaking command, the method further includes:

[0087] In response to the handle opening command, the handle opening operation is executed, controlling the handle to rotate from the initial position to the extended position;

[0088] If the handle does not extend 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 the current ambient temperature is obtained;

[0089] If the current ambient temperature is lower than the preset temperature threshold, then perform the normal ice-breaking operation;

[0090] If the handle does not extend after the routine ice-breaking operation is completed, a retraction ice-breaking command will be issued.

[0091] Specifically, when a user uses the vehicle, they first issue a handle opening command via the car key, handle button, or other devices. In response to this command, the motor rotates forward, driving the handle from its initial position to its extended position. The extension of the handle is then detected by checking if an opening detection switch is triggered. If the handle does not extend within a third preset time threshold, the number of times the handle opening operation has been executed is recorded. If the number of executions is less than a preset threshold, the handle is rotated back from its initial position to the extended position. If the number of executions is greater than or equal to the preset threshold, the handle is considered to be malfunctioning or frozen. The current ambient temperature is then recorded. If the current ambient temperature is less than a preset temperature threshold, the handle is determined to be frozen, and a standard ice-breaking operation is performed. This standard ice-breaking operation can be either a heating and melting operation or a high-torque stall-and-break operation. If the handle still does not extend after the standard ice-breaking operation, a retraction ice-breaking command is issued.

[0092] In this embodiment, after the handle opening operation is performed more than a preset threshold number of times, if the current ambient temperature indicates that the handle is frozen, a conventional ice-breaking operation is performed. If the ice-breaking fails, a retraction ice-breaking command 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 retraction ice-breaking operation is performed, and the handle can be rotated to the retraction position more smoothly.

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

[0094] Control the handle to rotate from the initial position toward the extended position, maintain the position for a preset time, and then control the handle to rotate back to the initial position.

[0095] After performing the above steps for the first preset number of times, determine whether the handle has extended.

[0096] In this embodiment, the conventional ice-breaking operation involves repeatedly controlling the handle to extend towards the ice layer and applying a pushing force to the ice layer at set intervals to achieve ice breaking by tapping.

[0097] Specifically, the motor is controlled to rotate forward, and after a set time of stall, the motor is controlled to rotate in reverse and retract. This process is repeated for the first preset number of times. If the handle still does not extend, the subsequent ice-breaking operation is performed.

[0098] Ideally, during normal ice-breaking operations, when controlling the motor to rotate, a maximum voltage of 16V can be supplied to the motor to increase the motor torque and give the handle the maximum ice-breaking force.

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

[0100] Standard icebreaking procedures also include:

[0101] Control the handle to rotate from the initial position toward the extended position, maintain the position for a preset time, and then control the handle to rotate back to the initial position.

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

[0103] Specifically, the heating element can be a heating coil, which is installed inside the handle and can be coiled along the handle surface to increase the heating area of ​​the handle surface. The conventional ice-breaking operation also includes repeatedly controlling the handle to extend towards the ice layer, applying a pushing force to the ice layer at set intervals to achieve ice-breaking by tapping, while simultaneously energizing the heating element to control its heating and melting of the ice. This simultaneous execution of both heating and tapping ice-breaking operations further improves ice-breaking efficiency. The specific execution method of the tapping ice-breaking operation can refer to the execution method of tapping ice-breaking in the aforementioned embodiments. The second preset number of times may or may not be equal to the first preset number of times.

[0104] Optionally, the conventional ice-breaking operation can first perform a tapping ice-breaking operation. If the handle cannot extend after the first preset number of tapping ice-breaking operations, the operation can continue for a second preset number of tapping ice-breaking operations. At the same time, the heating element is controlled to heat the ice, and the heating ice-breaking operation is carried out simultaneously to improve the ice-breaking efficiency.

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

[0106] Step S501: In response to the handle opening command, perform the handle opening operation and control the handle to rotate from the initial position to the extended position.

[0107] Step S502: If the handle does not extend 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 obtain the current ambient temperature.

[0108] Step S503: If the current ambient temperature is lower than the preset temperature threshold, control the handle to rotate from the initial position to the extended position, maintain the position for a preset duration, and then control the handle to rotate back to the initial position.

[0109] Step S504: After performing the above steps for the first preset number of times, if the handle does not extend, control the handle to rotate from the initial position to the extended position, maintain the position for a preset duration, and then control the handle to rotate back to the initial position while simultaneously controlling the heating element to heat and melt the ice.

[0110] Step S505: Execute the second preset number of steps above continuously. If the handle does not extend, issue a retraction ice-breaking command.

[0111] Step S506: In response to the retraction ice-breaking command, control the handle to rotate from the initial position toward the retraction position until the rotation time exceeds the first preset time threshold or the retraction detection switch is triggered. Then, determine that the handle has rotated to the retraction position, control the handle to stop rotating, so that an ice-breaking hole is formed between the ice layer and the surface of the handle for the user to manually break the ice from the outside.

[0112] Step S507: If a handle opening command is received, proceed to step S508; if a rewind ice breaking command is received, proceed to 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 off detection switch and the on detection switch are triggered in sequence, then determine that the handle has rotated to the extended position and control the handle to stop rotating.

[0114] Step S509: Determine whether the number of times the ice-breaking operation has been executed exceeds the preset threshold. If so, end the ice-breaking process; otherwise, control the handle to rotate from the initial position to the retraction position.

[0115] Concealed external handle structure:

[0116] The technical solution of this application also provides a concealed external handle structure for performing the concealed external handle ice-breaking method in the foregoing embodiments, such as... Figures 1-3 As shown in Figures 6 and 7, the device includes 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. The handle 02 is rotatably installed in the receiving space 11. The handle 02 can 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 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 recessed into the receiving space 11 relative to the surface of the base 01.

[0118] The drive assembly is installed on the inside of the base 01. The drive 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, such as Figure 6 , 7 As shown, the base 01 is mounted on the car door, the receiving space 11 faces the outer surface of the car door, the drive assembly is mounted inside the base 01, and the handle 02 is mounted in the receiving space and at least partially extends into the inside of the base 01 and is connected to the drive assembly. The drive assembly actuates to drive the handle to rotate, so that the handle moves as shown in the diagram. Figure 1 The initial position shown, as Figure 2 The pullback position shown and as Figure 3 Rotate between the extended positions shown.

[0120] In this embodiment, in order to enable the handle 02 to rotate to the retracted position, the base has a deeper receiving space than the existing structure, so that after the handle 02 rotates to the initial position, it can rotate further to the retracted 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, such as Figure 6 , 7 As shown, the drive device includes a drive motor 03, a push rod 04, and a rocker arm 05 rotatably mounted on the base 01;

[0122] One end of the push rod 04 is connected to the output shaft of the drive 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 drive 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 drive motor 03 rotates, causing the push rod 04 to extend and retract, so that the push rod 04 drives the rocker arm 05 to rotate around its axis. A limiting groove 51 is provided in the rocker arm 05. The handle 02 is rotatably mounted in the receiving space via a pivot. The handle 02 has a drive unit 21 that extends into the limiting groove 51. When the rocker arm 05 rotates, it drives the drive unit 21 to rotate through the limiting groove 51, causing the handle 02 to rotate. When the drive motor 03 drives the output shaft to rotate in the forward direction, the drive push rod 04 extends to push the rocker arm 05 forward. The rocker arm 05 drives the drive unit 21 to extend the handle 02 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. The rocker arm 05 drives the drive unit 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, such as Figure 8As shown, the rocker arm 05 is provided with a ball socket 52, and a freely movable ball head 41 is installed in the ball socket 52. 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 within the ball socket 52 and can move freely within the ball socket 52. The ball head 41 is connected to the push rod 04 via the steel wire rope 42. When the push rod 04 extends, it pushes the rocker arm 05 to rotate forward. When the push rod 04 retracts, it pulls the ball head 41. Since the ball head 41 is confined within the ball socket 52, the ball head 41 will pull the rocker arm 05 to rotate backward.

[0126] In this embodiment, 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 back and forth, thereby realizing the rotation of the handle 02 from the initial position to the retracted position.

[0127] In one embodiment, such as Figure 9 As shown, the push rod 04 has a protruding trigger block 43 on its side and a retraction detection switch 06 on its outer side. 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 this embodiment, a retraction detection switch 06 is provided on one side of the push rod 04. The retraction detection switch 06 can be a push-button switch, specifically, a mounting base 07 can be provided below the push rod 04, and the retraction detection switch 06 is mounted on the mounting base 07. The retraction detection switch 06 is located at the position of the trigger block 43 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.
