Description

Technical Field

[0001] This application relates to the field of refrigeration and freezing equipment technology, and in particular to a micro-switch foolproof mechanism and ice-making equipment. Background Technology

[0002] As people's living standards continue to improve, adding ice to various alcoholic beverages to make chilled drinks has become a common practice, resulting in a growing demand for ice-making equipment.

[0003] In existing technologies, some ice-making equipment has an ice box in the first position during the ice-making process. After ice making is complete, the ice box needs to be flipped to the second position to remove the ice. After the ice is removed, the ice box is flipped back to the first position. This process requires identifying the position of the ice-making chamber. Typically, two identification devices are installed on the ice chamber to identify the first and second positions of the ice box, respectively. However, during assembly, the two identification devices may be installed backwards, thus affecting the processing and production of the ice-making equipment. Summary of the Invention

[0004] In view of this, this application provides an ice-making device to solve the technical problem that two identification devices are installed backwards during the installation process of existing ice-making devices.

[0005] To achieve one, some, or all of the above objectives or other objectives, the technical solution of the present invention is as follows: In a first aspect, this application proposes a micro switch foolproof mechanism, comprising: a first micro switch, a second micro switch, a triggering structure, an actuating mechanism, and an assembly mechanism; The trigger structure is located on the movable mechanism and moves with the movable mechanism. The movement of the trigger structure triggers the first micro switch or the second micro switch. Both the first micro switch and the second micro switch are installed in the assembly mechanism, with the first micro switch located at one end of the active path of the trigger structure and the second micro switch located at the other end of the active path of the trigger structure. Both the first micro switch and the second micro switch have at least two terminals. The number of terminals in the first micro switch and the second micro switch are different, and / or the position of at least one terminal in the first micro switch is different from the position of each terminal in the second micro switch.

[0006] In some alternative implementations, the first microswitch has two terminals and the second microswitch has three terminals.

[0007] In some alternative embodiments, the two terminals of the first micro switch are a common terminal and a normally open terminal, respectively, and the three terminals of the second micro switch are a common terminal, a normally open terminal, and a normally closed terminal, respectively.

[0008] In some alternative embodiments, both the first microswitch and the second microswitch have two terminals, and the distance between the two terminals of the first microswitch is greater than the distance between the two terminals of the second microswitch.

[0009] In some alternative embodiments, the two terminals of the first micro switch are a common terminal and a normally open terminal, respectively, and one of the two terminals of the second micro switch is a common terminal, and the other terminal is a normally open terminal or a normally closed terminal.

[0010] In some alternative embodiments, the assembly mechanism is provided with a first stop plate, and one side of the first micro switch has a first terminal area with terminals installed and a first hollow area without terminals installed; the first stop plate is installed in the first hollow area.

[0011] In some alternative embodiments, the assembly mechanism is provided with a second stop plate, and one side of the second micro switch has a second terminal area with terminals installed and a second hollow area without terminals installed; the second stop plate is installed in the second hollow area. In some alternative embodiments, the movable mechanism is used to drive the trigger structure to rotate about a first axis, the trigger structure rotates in a first direction to contact a first micro switch, and the trigger structure rotates in a second direction to contact a second micro switch; Both the first micro switch and the second micro switch include a housing and a driving unit. The two ends of the driving unit are a connecting end and a free end, respectively. The connecting end is connected to the housing, and the free end swings under the action of the triggering structure. The swing direction of the free end of the first micro switch is opposite to the first direction, and the swing direction of the free end of the second micro switch is opposite to the second direction.

[0012] Secondly, this application proposes an ice-making device, comprising: an ice-making chamber, an ice box, a flipping mechanism, and a micro switch anti-foolproof mechanism provided in the first aspect. The ice box and the flipping mechanism are both installed in the ice-making chamber. The flipping mechanism is connected to the ice box to drive the ice box to flip from an ice-making state to a discharge state for discharging ice. A trigger structure is disposed in the ice box and flips with the ice box. A first micro switch and a second micro switch are disposed in the ice-making chamber.

[0013] In some alternative embodiments, the ice-making device further includes a controller and an alarm mechanism, the controller being connected to the flipping mechanism, the first micro switch, the second micro switch, and the alarm mechanism, respectively; During the process of the ice box switching from the ice-making state to the discharging state, the controller activates the flipping mechanism. After a first set delay, if the controller does not receive the trigger signal of the second micro switch, the controller controls the alarm mechanism to sound an alarm. During the process of switching the ice box from the discharging state to the ice-making state, the controller activates the flipping mechanism. After a first set delay, if the controller does not receive the trigger signal from the first micro switch, the controller controls the alarm mechanism to issue an alarm.

[0014] Implementing the embodiments of this application will have the following beneficial effects: Firstly, the microswitch foolproof mechanism provided in this application embodiment can be applied to ice-making equipment. The first microswitch and the second microswitch can serve as identification devices. A triggering structure can activate the first microswitch to instruct the ice box to move to a first position, and a triggering structure can activate the second microswitch to instruct the ice box to move to a second position. Because the first and second microswitches differ in the number and / or position of their terminals, they have significant differences in their structural appearance. Therefore, during the assembly of ice-making equipment using the microswitch foolproof mechanism, it is easy to distinguish between the first and second microswitches, thereby preventing them from being installed backwards to a certain extent.

[0015] Secondly, the ice-making equipment provided in the embodiments of this application uses the micro switch anti-mistake mechanism provided in the first aspect. The two identification devices in the ice-making equipment are the first micro switch and the second micro switch in the micro switch anti-mistake mechanism. The ice-making equipment using the micro switch anti-mistake mechanism can prevent the first micro switch and the second micro switch from being installed in reverse to a certain extent.

[0023] To illustrate the technical solutions described in this application, the following detailed description is provided in conjunction with specific drawings and embodiments.

[0024] This application provides a microswitch foolproof mechanism and an ice-making device. The microswitch foolproof mechanism provided in this embodiment can be applied to ice-making devices, as well as other devices that require identification of two different locations. The ice-making device provided in this embodiment utilizes the microswitch foolproof mechanism provided in this embodiment.

[0025] Taking the application of a micro switch anti-mistake mechanism in ice-making equipment as an example, this paper further explains the micro switch anti-mistake mechanism and the ice-making equipment using the micro switch anti-mistake mechanism.

[0026] like Figures 1 to 3 As shown in the figure, this application proposes a micro switch foolproof mechanism, including: a first micro switch 410, a second micro switch 420, a trigger structure 300, an actuating mechanism 200, and an assembly mechanism 100. Both the first micro switch 410 and the second micro switch 420 are mounted on the assembly mechanism 100, with the first micro switch 410 located at one end of the actuating path of the trigger structure 300 and the second micro switch 420 located at the other end of the actuating path of the trigger structure 300. Both the first micro switch 410 and the second micro switch 420 have at least two terminals 430. The number of terminals 430 in the first micro switch 410 and the second micro switch 420 are different, and / or the position of at least one terminal 430 in the first micro switch 410 is different from the position of each terminal 430 in the second micro switch 420.

[0027] The ice-making device includes an ice-making chamber 10, an ice box 20, a flipping mechanism, and a microswitch anti-foolproof mechanism provided in this embodiment. The ice box 20 and the flipping mechanism are both installed in the ice-making chamber 10. The flipping mechanism is connected to the ice box 20 to drive the ice box 20 from an ice-making state to a discharging state for discharging ice. A trigger structure 300 is disposed on the ice box 20 and flips with it. A first microswitch 410 and a second microswitch 420 are disposed in the ice-making chamber 10. Exemplarily, the flipping mechanism may include a motor. The motor may be directly connected to the ice box 20 or connected via a reducer.

[0028] The ice-making equipment provided in this application can be an independent ice-making device, such as an embedded ice-making device, a tabletop ice-making device, a portable ice-making device, etc., or it can be an ice-making device applied to other devices, such as an ice-making device applied to appliances such as refrigerators and water dispensers.

[0029] The trigger structure 300 is disposed on and moves with the movable mechanism 200. The trigger structure 300 moves to trigger either the first microswitch 410 or the second microswitch 420. It is worth noting that when applying the microswitch foolproof mechanism to an ice-making device, the ice box 20 in the ice-making device can be used as the movable mechanism 200, or the movable mechanism 200 can be connected to the ice box 20. This allows the movement of the ice box 20 to drive the trigger structure 300. The ice box 20 moves by rotating around a first axis, which in turn causes the trigger structure 300 to swing around the first axis. The ice box 20 can rotate between a first position and a second position. When the ice box 20 is in the first position, it is in the ice-making state; when it is in the second position, it is in the position where ice is being discharged. The trigger structure 300 can trigger the first micro switch 410 by swinging around the first axis in a first direction to one end of the active path, and the trigger structure 300 can trigger the second micro switch 420 by swinging around the first axis in a second direction to the second end of the active path. One of the first direction and the second direction is clockwise, and the other is counterclockwise. When the trigger structure 300 is at one end of the active path, the ice box 20 is located in one of the first position and the second position; when the trigger structure 300 is at the other end of the active path, the ice box 20 is located in the other of the first position and the second position.

[0030] In one specific example, the ice box 20 is used as the moving mechanism 200, and the ice-making chamber 10 is used as the assembly mechanism 100. The first microswitch 410 and the second microswitch 420 are both installed on the outside of the ice-making chamber 10. The ice box 20 is rotatably installed on the inside of the ice-making chamber 10. The ice box 20 is connected to the trigger structure 300, and the ice box 20 can drive the trigger structure 300 to rotate around the first axis. Figures 1 to 3In the middle, the trigger structure 300 contacts the first microswitch 410, and the ice box 20 is in the first position, at which time the opening of the ice box 20 faces upward, for holding water and making ice. Figures 4 to 6 In this configuration, the trigger structure 300 contacts the second microswitch 420, and the ice box 20 is in the second position with its opening tilted downwards to facilitate pouring out the ice cubes made inside. In this arrangement, the trigger signal of the first microswitch 410 indicates that the ice box 20 is in the first position, ready for ice making; the trigger signal of the second microswitch 420 indicates that the ice box 20 is in the second position, ready for ice removal. It is understandable that in other configurations, the installation positions of the first microswitch 410 and the second microswitch 420 can be changed so that the trigger structure 300 triggers the first microswitch 410 when the ice box 20 is in the second position, and triggers the second microswitch 420 when the ice box 20 is in the first position. It is worth noting that in the following text, the operation status of the ice-making equipment will be described using the example of the trigger structure 300 triggering the first micro switch 410 when the ice box 20 is in the first position and triggering the second micro switch 420 when the ice box 20 is in the second position.

[0031] It is worth noting that when the micro switch foolproof mechanism is applied to other devices, the active mechanism 200 can also move back and forth along a straight line or other shaped path with the trigger structure 300. The trigger structure 300 is not limited to only swinging.

[0032] The assembly mechanism 100 is used to install the first micro switch 410 and the second micro switch 420. When the micro switch foolproof mechanism is applied to the ice-making equipment, the ice-making chamber 10 in the ice-making equipment can be used as the assembly mechanism 100, or the assembly mechanism 100 can be fixedly installed on the ice-making chamber 10. The ice box 20 is rotatably connected to the ice-making chamber 10. The ice-making equipment also includes a flipping mechanism, which is connected to the ice box 20 to drive the ice box 20 to flip from the ice-making state to the ice-discharging state. In other words, the flipping mechanism is used to drive the ice box 20 to flip between the first position and the second position.

[0033] Both the first micro switch 410 and the second micro switch 420 are provided with at least two terminals 430. In one case, the number of terminals 430 of the first micro switch 410 is different from the number of terminals 430 of the second micro switch 420. The first micro switch 410 and the second micro switch 420 can be distinguished by the number of terminals 430, thereby reducing the possibility of the first micro switch 410 and the second micro switch 420 being installed backwards.

[0034] In another scenario, the location of at least one terminal 430 of the first micro switch 410 differs from the location of each terminal 430 in the second micro switch 420. For example, a terminal 430 is provided in region A of the first micro switch 410, while no terminal 430 is provided in region A of the second micro switch 420. In this case, the presence or absence of a terminal 430 in region A of the micro switch can be used to determine whether the micro switch is the first micro switch 410 or the second micro switch 420, thereby reducing the possibility of the first micro switch 410 and the second micro switch 420 being installed backwards.

[0035] In another case, the number of terminals 430 in the first micro switch 410 and the second micro switch 420 are different, and the installation positions of the terminals 430 are different. This makes the appearance structure of the first micro switch 410 and the second micro switch 420 more different, thereby reducing the possibility of the first micro switch 410 and the second micro switch 420 being installed backwards.

[0036] In summary, because the first micro switch 410 and the second micro switch 420 differ in the number and / or position of the terminals 430, they have significant differences in structural appearance. Therefore, during the assembly of ice-making equipment with a micro switch anti-foolproof mechanism, it is easy to distinguish between the first micro switch 410 and the second micro switch 420, thereby preventing the first micro switch 410 and the second micro switch 420 from being installed backwards to a certain extent.

[0037] In some embodiments, the ice-making device further includes a controller and an alarm mechanism. The controller is connected to a flipping mechanism, a first micro switch 410, a second micro switch 420, and the alarm mechanism, respectively. During the process of the ice box 20 switching from the ice-making state to the discharging state, the controller activates the flipping mechanism. After a first set time delay, if the controller does not receive a trigger signal from the second micro switch 420, the controller controls the alarm mechanism to sound an alarm. During the process of the ice box 20 switching from the discharging state to the ice-making state, the controller activates the flipping mechanism. After a first set time delay, if the controller does not receive a trigger signal from the first micro switch 410, the controller controls the alarm mechanism to sound an alarm.

[0038] A controller can be installed in the ice-making equipment. This controller can be an MCU (Microcontroller Unit), CPU (Central Processing Unit), PLC (Programmable Logic Controller), microcontroller, or other similar control mechanism. The controller is connected to a tilting mechanism to control its operation, thereby moving the ice container 20 between a first position and a second position, switching between ice-making and dispensing states. The controller is also connected to a first microswitch 410 and a second microswitch 420 to determine whether the ice container 20 has moved to its correct position based on the trigger states of these switches. The time required for the ice container 20 to move to its correct position can be calculated using the motor speed and the required rotation angle between the first and second positions. A first set time is greater than or equal to the time required for the ice container 20 to move to its correct position. For example, if the flipping mechanism can move the ice box 20 from the first position to the second position or from the second position to the first position 3 seconds after the controller starts the flipping mechanism, then the first set time can be 3 seconds or more than 3 seconds, for example, the first set time can be 4 seconds.

[0039] During the transition from ice-making to discharging state of ice container 20, the controller activates the tilting mechanism. After a first set delay, if the ice-making equipment is operating normally, the controller will receive a trigger signal from the second microswitch 420 within the first set time. If the controller does not receive the trigger signal from the second microswitch 420, it indicates a problem with the ice-making equipment, such as a malfunction in the tilting mechanism, ice container 20, or the second microswitch 420. The controller will then activate the alarm mechanism to alert the user, allowing them to promptly inspect and troubleshoot the ice-making equipment. Similarly, during the transition from discharging to ice-making state of ice container 20, the controller activates the tilting mechanism. After a first set delay, if the ice-making equipment is operating normally, the controller will receive a trigger signal from the first microswitch 410 within the first set time. If the controller does not receive the trigger signal from the first microswitch 410, it indicates a problem with the ice-making equipment, such as a malfunction in the tilting mechanism, ice container 20, or the first microswitch 410. The controller will then activate the alarm mechanism to alert the user, allowing them to promptly inspect and troubleshoot the ice-making equipment.

[0040] The alarm mechanism may include at least one of a buzzer, an indicator light, and a display screen. For example, an alarm may be triggered by the sounding of a buzzer, by switching the on / off state of an indicator light or by activating a flashing state, or by displaying text or symbols indicating a fault on a display screen.

[0041] The controller can be directly or indirectly connected to the first microswitch 410 and the second microswitch 420, so that the controller can receive trigger signals from the first microswitch 410 and the second microswitch 420. For example... Figure 7 As shown, the ice-making equipment also includes a connector, which connects to the controller. The connector can also connect to multiple electronic components, allowing indirect connection between the multiple electronic components and the controller. Figure 7 In this circuit, the connector (shown as CN17 in the figure) has at least four interfaces. One interface (shown as 1 in the figure) is grounded, another interface (shown as 4 in the figure) is connected to a 3.3V power supply, one interface (shown as 3 in the figure) is connected to a first microswitch 410 (shown as K1 in the figure) via a first line, and another interface (shown as 2 in the figure) is connected to a second microswitch 420 (shown as K2 in the figure) via a second line. A resistor R1 is placed between the power supply and the first line, and a resistor R2 is placed between the power supply and the second line. A test point T1 and a resistor R3 are placed on the first line, and a test point T2 and a resistor R4 are placed on the second line. Resistor R3 is located between the first microswitch 410 and the test point T1, and resistor R4 is located between the second microswitch 420 and the test point T2. The circuit also includes capacitors C1 and C2. One end of capacitor C1 is connected to the area in the first line between resistor R3 and the first microswitch 410, and the other end is grounded. One end of capacitor C2 is connected to the area between resistor R4 and the second microswitch 420K2 in the second circuit, and the other end is grounded. The first microswitch 410 can be normally open or normally closed, and the second microswitch 420 can be normally open or normally closed. Figure 7 In this circuit, both the first microswitch 410 and the second microswitch 420 are normally open.

[0042] Resistors R1, R2, R3, and R4 are all used for current limiting to prevent overcurrent damage to components. The values ​​of R1 and R2 can be matched to the operating current of the microswitch and the input characteristics of the controller to ensure stable and reliable signal. The entire detection circuit ensures functionality while also considering safety and maintainability.

[0043] The power supply is used for power supply. Taking the circuit containing the first microswitch 410 as an example, when the first microswitch 410 is normally open, it is in the open state when it is not triggered, and the power supply keeps the circuit at a high level. When the first microswitch 410 is closed, the circuit becomes low-level. If the first microswitch 410 is normally closed, it is in the closed state when it is not triggered, and the circuit is low-level. When the first microswitch 410 is triggered, it is in the open state, and the power supply keeps the circuit at a high level. As can be seen, triggering the microswitch can switch the circuit between high-level and low-level states. The controller can monitor the voltage state (high level or low level) of the circuit to obtain the state of the first microswitch 410 and the second microswitch 420, and thus determine whether the first microswitch 410 and the second microswitch 420 have been triggered.

[0044] Capacitors C1 and C2 are used for filtering. Test points T1 and T2 are used to test whether there are faults in the components of the circuit during the production process.

[0045] like Figure 8 and Figure 9As shown, in some alternative embodiments, the first micro switch 410 has two terminals 430, and the second micro switch 420 has three terminals 430. Of the two terminals 430 of the first micro switch 410, one is a common terminal, and the other is either a normally open terminal or a normally closed terminal. When the other terminal 430 is a normally open terminal, the first micro switch 410 is a normally open switch; when the other terminal 430 is a normally closed terminal, the first micro switch 410 is a normally closed switch. The three terminals 430 of the second micro switch 420 are a common terminal, a normally open terminal, and a normally closed terminal, respectively. The second micro switch 420 may use only two terminals 430, for example, when the common terminal is connected to the circuit, one of the normally open terminal and the normally closed terminal may also be connected to the circuit. In this configuration, the number of terminals 430 of the first micro switch 410 is less than that of the second micro switch 420. The first micro switch 410 can be formed by modifying the second micro switch 420; for example, one terminal 430 of the second micro switch 420 can be cut off, resulting in a first micro switch 410 with two terminals 430. With this configuration, the first micro switch 410 does not need to be designed and manufactured separately, reducing production costs. The second micro switch 420 can be designed and manufactured independently, or a micro switch from the prior art can be used. For example, if a micro switch with three terminals 430 exists in the prior art, this three-terminal micro switch can be used as the second micro switch 420, and one terminal 430 of the three-terminal micro switch can be cut off to form the first micro switch 410, further reducing design and production costs. In one example, [the following text is missing from the original extract]. Figure 9 The second micro switch 420 can be modified by cutting off the terminal 430 located in the middle. Figure 8 The first microswitch 410 in the middle. In another example, will Figure 9 The second micro switch 420 can be modified by cutting off the right-side terminal 430. Figure 10 The first micro switch 410 in the middle.

[0046] like Figure 8 and Figure 9As shown, in some optional embodiments, the two terminals 430 of the first micro switch 410 are a common terminal and a normally open terminal, respectively, and the three terminals 430 of the second micro switch 420 are a common terminal, a normally open terminal, and a normally closed terminal, respectively. In this configuration, the first micro switch 410 is a normally open switch, and the second micro switch 420 can be either a normally open switch or a normally closed switch. When the normally open terminal of the second micro switch 420 is connected to the circuit, the second micro switch 420 is a normally open switch; when the normally closed terminal of the second micro switch 420 is connected to the circuit, the second micro switch 420 is a normally closed switch. Since the second micro switch 420 can be selectively connected to either a normally open terminal or a normally closed terminal, it can be used as a normally open switch or a normally closed switch as needed.

[0047] like Figure 8 and Figure 11 As shown, in some optional embodiments, both the first micro switch 410 and the second micro switch 420 have two terminals 430, and the distance between the two terminals 430 of the first micro switch 410 is greater than the distance between the two terminals 430 of the second micro switch 420. With this configuration, even if the first micro switch 410 and the second micro switch 420 have the same number of terminals 430, they can be distinguished by the distance between adjacent terminals 430.

[0048] In some alternative embodiments, the two terminals 430 of the first micro switch 410 are a common terminal and a normally open terminal, respectively. Of the two terminals 430 of the second micro switch 420, one terminal 430 is a common terminal, and the other terminal 430 is either a normally open terminal or a normally closed terminal. In this configuration, the first micro switch 410 is a normally open switch, and the second micro switch 420 can be either a normally open switch or a normally closed switch. When the other terminal 430 of the second micro switch 420 is a normally open terminal, the second micro switch 420 is a normally open switch; when the other terminal 430 of the second micro switch 420 is a normally closed terminal, the second micro switch 420 is a normally closed switch. Figure 8 In the first micro switch 410, the two terminals 430 are a common terminal and a normally open terminal, respectively. Figure 11In this configuration, the two terminals 430 of the second microswitch 420 are a common terminal and a normally closed terminal, respectively. In this arrangement, the first microswitch 410 and the second microswitch 420 can be modified from the existing three-terminal microswitch 430. For example, taking a microswitch with three terminals 430 (left, center, and right), the middle terminal 430 can be cut off, leaving only the left and right terminals 430, resulting in a larger distance between the two terminals 430, thus creating the first microswitch 410. Similarly, the right terminal 430 of the microswitch can be cut off, leaving only the left and center terminals 430, resulting in a smaller distance between the two terminals 430, thus creating the second microswitch 420.

[0049] like Figure 6 , Figure 8 and Figure 10 As shown, in some optional embodiments, the assembly mechanism 100 is provided with a first stop plate 110, and one side of the first micro switch 410 has a first terminal 430 area where a terminal 430 is installed and a first hollow area 461 where no terminal 430 is installed; the first stop plate 110 is installed in the first hollow area 461. In this arrangement, during the assembly process, because of the presence of the first stop plate 110, the second micro switch 420, whose terminal 430 is located differently from that of the first micro switch 410, cannot be installed in the mounting area of ​​the first micro switch 410. For example, terminals 430 are respectively provided at both ends of one side of the first micro switch 410, and the area between the two terminals 430 is the first cutout area 461. Terminals 430 are provided at both ends and in the middle of one side of the second micro switch 420. If the second micro switch 420 is to be installed in the mounting position of the first micro switch 410, the first stop plate 110 and the terminal 430 in the middle of the second micro switch 420 conflict, so that the second micro switch 420 cannot be placed in the mounting position of the first micro switch 410 for subsequent installation, thereby preventing the first micro switch 410 and the second micro switch 420 from being installed backwards.

[0050] In some alternative embodiments, the assembly mechanism 100 is provided with a second stop plate (not shown in the figure), and one side of the second micro switch 420 has a second terminal 430 area on which the terminal 430 is mounted and a second hollow area 462 on which the terminal 430 is not mounted (e.g., Figure 11(As shown); the second stop plate is installed in the second cutout area 462. Since at least one terminal 430 of the first micro switch 410 is installed in a position different from all terminals 430 of the second micro switch 420, during the process of installing the first micro switch 410 into the mounting position of the second micro switch 420, the second stop plate conflicts with one of the terminals 430 of the first micro switch 410, making it impossible for the first micro switch 410 to be placed into the mounting position of the second micro switch 420 for subsequent installation, thereby preventing the first micro switch 410 and the second micro switch 420 from being installed backwards.

[0051] like Figure 12 and Figure 13 As shown, in some optional embodiments, the movable mechanism 200 is used to drive the trigger structure 300 to rotate about a first axis. The trigger structure 300 rotates in a first direction to contact the first micro switch 410, and rotates in a second direction to contact the second micro switch 420. Both the first micro switch 410 and the second micro switch 420 include a housing 440 and a driving part 450. The two ends of the driving part 450 are a connecting end 451 and a free end 452, respectively. The connecting end 451 is connected to the housing 440, and the free end 452 swings under the action of the trigger structure 300. The swing direction of the free end 452 of the first micro switch 410 is opposite to the first direction, and the swing direction of the free end 452 of the second micro switch 420 is opposite to the second direction. The terminal 430 and the driving part 450 are both mounted on the housing 440. At least a portion of the terminal 430 is located inside the housing 220, and a portion is located outside the housing 440. The free end 452 of the driving part 450 is located outside the housing 440. The drive unit 450 may be a rocker arm or a spring. For example, in... Figure 12 In the first direction, which is counterclockwise, the trigger structure 300 rotates counterclockwise to contact the first micro switch 410, causing the drive part 450 of the first micro switch 410 to swing clockwise a certain distance, thereby triggering the first micro switch 410. Figure 13 In this configuration, the second direction is clockwise. After the trigger structure 300 rotates clockwise, it can contact the drive part 450 of the second micro switch 420, causing the drive part 450 of the second micro switch 420 to swing counterclockwise a certain distance, thereby triggering the second micro switch 420. In this configuration, after the trigger structure 300 contacts the drive part 450, the friction between the trigger structure 300 and the drive part 450 is relatively small, which helps to reduce wear on the contact area between the drive part 450 and the trigger structure 300, and also helps to improve the response speed of the first micro switch 410 and the second micro switch 420.

[0052] In one example, the terminal 430 of the micro switch (first micro switch 410 or second micro switch 420) can be connected by on-board soldering, directly fixed to the pads on the controller's circuit board via soldering, thus achieving integrated installation. In another example, the terminal 430 of the micro switch can be connected by wire lead-out, establishing a mechanical and electrical connection with the wire at the terminal 430 through crimping, riveting, or soldering, using the wire as an intermediate transmission medium to connect the micro switch to the circuit.

[0053] When the terminal 430 of the micro switch is connected by a wire lead-out, two wire harness clips can be provided on the assembly mechanism 100. The wire harness clips are arranged opposite to the terminal 430 of the micro switch that is connected to the wire, and the wire harness clips are used to fix the wire.

[0054] In one example, the first microswitch 410 includes two terminals 430. A wire harness clip (not shown) is provided on the assembly mechanism 100 corresponding to each of the two terminals 430. The two wire harness clips correspond one-to-one with the two terminals 430 and are spaced apart. When both terminals 430 are located on the left side of the housing 440 of the first microswitch 410, the wire harness clip is located on the left side of its corresponding terminal 430 and has a certain distance between it and the terminal 430. One wire harness clip is used to limit and fix the wire connected to one terminal 430, and the other wire harness clip is used to limit and fix the wire connected to the other terminal 430. The wire harness clip may include a limiting ring with a notch. The wire can enter the limiting ring through the notch, and the limiting ring radially limits the wire.

[0055] In another example, the second microswitch 420 includes three terminals 430, two of which are used to connect wires, and the third terminal 430 is not connected to a wire. A wire harness clip is provided on the assembly mechanism 100 corresponding to the two terminals 430 connected to the wires, and no wire harness clip is provided opposite to the terminal 430 not used to connect the wire. In this arrangement, the wire harness clip serves two purposes: firstly, to limit the wires connected to the terminals 430 of the second microswitch 420, and secondly, to determine whether the wires of the second microswitch 420 are connected to the correct terminals 430. For example, terminals 430 are provided on the left, middle, and right sides of one side of the second microswitch 420, with the left and right terminals 430 used to connect wires, and the middle terminal 430 not connected to a wire. Wire harness clips are then provided corresponding to the left and right terminals 430. If the wires in the second micro switch 420 are connected to the wrong terminal 430, for example, if the wires are connected to the left and middle terminals 430 but not to the right terminal 430, then during the process of installing the second micro switch 420 into the assembly mechanism 100, the wires connected to the left terminal 430 can be fixed in the corresponding wire harness clips, but the wires connected to the middle terminal 430 do not have corresponding wire harness clips for fixing. In this case, it can be determined that there is a problem with the wire connection position in the second micro switch 420, so that the wire position can be adjusted in time.

[0056] The above-disclosed embodiments are merely preferred embodiments of this application and should not be construed as limiting the scope of this application. Therefore, any equivalent variations made in accordance with the claims of this application shall still fall within the scope of this application.
