Description

Technical Field

[0001] This application relates generally to the technical field of cookware, and more specifically to a cooking utensil. Background Technology

[0002] Cooking appliances in related technologies use electronic controls to operate a motor, enabling the lid and pot body to lock and unlock automatically. However, the locking and unlocking methods are relatively simple and cannot meet users' needs for a more flexible operating experience.

[0003] Therefore, there is a need to provide a cooking appliance that can at least partially solve the above problems. Utility Model Content

[0004] The utility model description section introduces a series of simplified concepts, which will be further explained in detail in the detailed description section. This utility model description section is not intended to limit the key features and essential technical features of the claimed technical solution, nor is it intended to determine the scope of protection of the claimed technical solution.

[0005] To at least partially solve the above problems, this application provides a cooking appliance, the cooking appliance comprising:

[0006] pot body;

[0007] A lid, which is foldably disposed on the pot body to form a cooking space between the lid and the pot body;

[0008] A lid-locking and lid-opening assembly, movably disposed on the lid body, having a locked state for locking the pot body and the lid, and an unlocked state for unlocking the pot body and the lid, the lid-locking and lid-opening assembly including a force-transmitting component; and

[0009] An operating element is disposed outside the cover body. The operating element is arranged correspondingly to the force transmission element and is tractively connected to the force transmission element. The operating element is configured to actuate the force transmission element when operated, so as to switch the cover opening assembly between the locked state and the unlocked state.

[0010] According to the cooking appliance of this application, the user can actuate the force transmission component by applying an operating force to the operating component, thereby switching the lid locking and unlocking assembly to a locked state or an unlocked state. Using the cooking appliance of this application allows the user to manually adjust the state of the lid locking and unlocking assembly in situations such as malfunctions in the electronic control system or when manual control is required, thus meeting the user's need for operational flexibility and improving the user experience.

[0011] Optionally, the operating element is magnetically actuated to the force transmission element.

[0012] According to this application, by connecting the operating component to the force transmission component in a magnetic manner, contactless transmission between the operating component and the force transmission component can be achieved, which helps to reduce the structural complexity of the cover and makes the cover easier to manufacture.

[0013] Optionally, one of the operating element and the force transmission element includes a magnetic body, and the other of the operating element and the force transmission element includes a magnetic conductor, wherein the magnetic body attracts the magnetic conductor through magnetic attraction; or

[0014] The operating component and the force transmission component each include a magnetic body.

[0015] According to this application, by providing a magnetic body in one of the operating component and a magnetic conductor in the other, or by providing a magnetic body in both the operating component and the force transmission component, it is possible to enable the operating component to drive the force transmission component to move through magnetic attraction, thereby changing the state of the cover locking and opening assembly.

[0016] Optionally, the operating element is fixedly connected to the force transmission element.

[0017] According to this application, by fixing the operating element to the force transmission element, the operating element and the force transmission element can directly transmit force, thereby improving the efficiency and reliability of force transmission.

[0018] Optionally, a movement path indicator is provided on the outside of the cover, and the operating member moves along the movement path indicator to change the state of the cover locking and opening assembly.

[0019] According to this application, by providing a movement path indicator, the user can move the operating component according to the indicated path of the movement path indicator, thereby helping to improve the accuracy of the user's operation.

[0020] Optionally, the movement path indicator is configured as a guide groove; or

[0021] The movement path indicator is configured as a guide hole.

[0022] According to this application, the movement path indicator is constructed as a guide groove or a guide hole. The guide groove is suitable for embodiments where the operating member and the force transmission member are connected by magnetic attraction, and the guide hole is suitable for embodiments where the operating member and the force transmission member are fixedly connected. This not only enables better positioning and guidance of the operating member, but also further improves the accuracy of the operating member when it is operated.

[0023] Optionally, the cover is provided with a movement direction indicator, which is arranged correspondingly to the movement path indicator.

[0024] According to this application, by providing a movement direction indicator, it is easier for users to identify the relationship between the movement direction of the operating component and the state of the locking and unlocking components, thereby improving the accuracy and efficiency of the user's operation of the operating component.

[0025] Optionally, the cover locking and unlocking assembly includes:

[0026] A fastening element is movably connected to the lid in a locked position and an unlocked position along the radial direction of the lid. When the lid is closed on the pot body, the fastening element in the locked position prevents the lid from being opened, and the fastening element in the unlocked position allows the lid to be opened.

[0027] A rotating frame is rotatably connected to the cover about a first axis and is driven to the fastening member to move the fastening member between the locked position and the unlocked position. The force transmission member is driven to the rotating frame and can be used to drive the rotating frame to rotate.

[0028] According to this application, when the operating component is operated by the user, the force is transmitted to the rotating frame through the force transmission component, thereby driving the fastening component to move between the locked position and the unlocked position through the rotation of the rotating frame, thereby achieving the purpose of manually changing the state of the cover opening assembly.

[0029] Optionally, the cooking appliance further includes a transmission connector rotatably connected to the cover about a second axis. The transmission connector has a rotation center and a free end. The rotation center is located at the second axis, and the free end is drively connected to the rotating frame. The second axis is parallel to the first axis. The transmission connector includes the force-transmitting element, and the force-transmitting element is located on the side of the second axis away from the free end.

[0030] According to this application, the force transmission component is part of the transmission connector. Here, the transmission connector enables force transmission between the operating component and the rotating frame, so that when the operating component is operated, it can actuate the rotating frame, thereby moving the fastening component and achieving the purpose of manually changing the state of the cover opening / closing assembly. Since the force transmission component is located on the side of the second axis away from the free end of the transmission connector, it helps to reduce the space occupied by the force transmission component between the second axis and the rotating frame, improving the rationality of the spatial layout and the flexibility of operation.

[0031] Optionally, the cooking appliance further includes:

[0032] A drive motor is connected to the cover opening assembly to actuate the cover opening assembly.

[0033] According to this application, by setting a drive motor, the state of the cover locking and opening assembly can be changed automatically. Attached Figure Description

[0078] The terms “parallel” / “perpendicular” and similar expressions used in this application include absolute parallel / perpendicular relationships and approximately parallel / perpendicular relationships (e.g., relationships that differ from absolute parallel / perpendicular relationships by a range of -5° to +5°), and have equivalent effects.

[0079] The specific embodiments of this application will be described in more detail below with reference to the accompanying drawings, which illustrate representative embodiments of this application and are not intended to limit this application.

[0080] like Figures 1 to 13 As shown, this application provides a cooking appliance. The cooking appliance of this application can be an electric pressure cooker, electric slow cooker, electric hot pot, soy milk maker, blender, or other electric cooking appliances. The cooking appliance may include a cooker body 100, a lid 110, a position detection device 140, a drive motor 134, and a control circuit board 116.

[0081] The pot body 100 is used for cooking food. The lid 110 is used to cover the pot body 100. For example, the lid 110 is connected to the pot body 100 in an openable and closable manner to cover the pot body 100. When the lid 110 covers the pot body 100, a cooking space is formed between the lid 110 and the pot body 100.

[0082] See Figure 2 The pot body 100 includes a pot inner 101, a middle frame 102, a heating device (not shown), a base, and a temperature detection device (not shown). The pot inner 101, used for holding food, is removably installed in the pot body 100. The middle frame 102 can be referred to as a heat insulation cover. The middle frame 102 is located between the outer circumferential side of the pot inner 101 and the base 103 and is fixed to the base 103, suitable for positioning the pot inner 101 and also serving a heat insulation function. When the lid 110 closes the pot body 100, a cooking space is formed between the lid 110 and the pot inner 101. The heating device is located below the pot inner 101 to heat the pot inner 101.

[0083] The control circuit board 116 includes a control unit, a digital display device, and circuitry. The control unit, for example, can be a microcontroller unit (MCU) used to control the cooking process of the cooking appliance. Figure 2 As shown, the control circuit board 116 can be installed in the cover 110.

[0084] A temperature detection device is used to detect the temperature of the cooking space or related to the cooking space. The temperature detection device includes a bottom temperature detection device and a top temperature detection device. The bottom temperature detection device is located, for example, at the bottom or side of the pot body, to detect the temperature of the bottom of the pot or indirectly the bottom of the cooking space. The top temperature detection device is located, for example, at the lid body, to detect the temperature of the top of the cooking space. Both the heating element and the temperature detection device are electrically connected to the control unit. The temperature detection device feeds back the sensed temperature information to the control unit, allowing the control unit to perform more precise control of, for example, the heating element, based on the temperature information.

[0085] See Figures 1 to 4,as well as Figure 6 and Figure 7 One end of the lid 110 in the front-rear direction D1 is rotatably connected to the pot body 100 via a pivot shaft about the rotation axis AX. An opening torsion spring 104 is mounted on the pivot shaft. Both ends of the opening torsion spring 104 abut against the lid 110 and the pot body 100 respectively, allowing the opening torsion spring 104 to apply an elastic force to the lid 110 away from the pot body 100. When the lid 110 is opened, it springs upward under the elastic force of the opening torsion spring 104 and rotates about the pivot shaft. The other end of the lid 110 in the front-rear direction D1 is detachably connected to the pot body 100 via a lid-closing hook 160.

[0086] See Figures 2 to 4 The lid 110 includes a top cover 111, a liner 112, and an inner cover 113. In addition, the lid 110 may also include electrical components, valve components, etc. Therefore, the assembly of the top cover 111, liner 112, and inner cover 113 can also be referred to as the lid body 117. It is understood that the lid body 117 may only have the degree of freedom to rotate about the axis of rotation AX relative to the cookware body 100. The top cover 111 is located at the outermost (i.e., uppermost) side of the lid 110, forming the outer shell of the lid 110. The top cover 111 may include a top cover body 111a and a panel 111b. The liner 112 is disposed below the top cover 111 and connected to the top cover 111. For example, the liner 112 can be connected to the top cover 111 via fasteners, snap-fit ​​connectors, etc. The liner 112 is mainly used to centrally mount various functional components of the lid 110 that sense and control the working status of the pressure cooking appliance, such as sensors. The inner cover 113 is located at the innermost (i.e., lowest) side of the cover body 110 and is positioned below the liner 112. The inner cover 113 is detachably connected to the liner 112 via a snap-fit ​​or other detachable connector for easy cleaning and replacement. The inner cover 113 is oriented towards the cooking space. That is, when the cover body 110 is closed on the pot body 100, the inner cover 113 is positioned directly above the cooking space. Furthermore, an inner cover sealing ring 1131 is provided on the outer periphery of the inner cover 113. The inner cover sealing ring 1131 is used to seal the gap between the inner cover 113 and the pot body 101 when the inner cover 113 is closed with the pot body 101.

[0087] See Figure 4The cover 110 is equipped with a steam valve 114 and an electric pressure relief device 120. The steam valve 114 has a steam vent (not shown in the figure) that communicates with the outside environment. A steam passage 110a, communicating with the steam valve 114, is also provided inside the cover 110. The cooking space is connected to the external environment through the steam passage 110a and the steam valve 114. The external environment refers to the environment outside the pressure cooking appliance. In this application, the steam valve 114 is used to connect the cooking space to the external environment to release steam generated during cooking. The electric pressure relief device 120 is electrically connected to a control unit and is controlled to switch between an open state (open steam passage 110a) and a closed state (closed steam passage 110a).

[0088] To reduce heat loss during cooking, the pot body 100 includes the aforementioned heat-insulating cover, such as... Figure 2 As shown. In this design, the fastening element 131 can engage with the edge of the inner pot 101 or the edge of the insulation cover. For example, in a rice cooker, the fastening element 131 can engage with the edge of the inner pot 101. For example, in an electric pressure cooker, the edge of the insulation cover is at least partially exposed, and the fastening element 131 can engage with the edge of the insulation cover. For ease of explanation, the following description will focus on the example of the fastening element 131 engaging with the edge of the inner pot 101.

[0089] See Figures 2 to 6The cooking appliance may also include a locking / unlocking assembly 130 and a power source. The locking / unlocking assembly 130 is connected to the power source to switch between a locked state and an unlocked state under the drive of the power source. In the locked state, the locking / unlocking assembly 130 prevents the removable cover 113 of the lid 110 from separating from the inner pot 101. In the unlocked state, the locking / unlocking assembly 130 allows the removable cover 113 to separate from the inner pot 101. The inner cover 113 has a radial direction and an axial direction. The radial direction is the radial direction of a circle about the geometric center of the inner cover 113. The axial direction is the direction passing through the geometric center of the inner cover 113 and parallel to the thickness direction of the inner cover. Here, the geometric center of the inner cover 113, in the example where the inner cover is circular, is the exact center of the inner cover or the center of the circle. The locking / unlocking assembly 130 includes a fastening element 131. The fastening element 131 is movably connected to the cover body 110 in a locked and unlocked position along the radial direction of the inner cover 113. The locking and unlocking assembly 130 is locked when the fastening element 131 is in the locked position. The locking and unlocking assembly 130 is unlocked when the fastening element 131 is in the unlocked position. The fastening element 131 may include a clamp for receiving the edge of the inner pot 101 and the edge of the inner cover 113. When the fastening element 131 is in the locked position, the edge of the inner pot 101 and the edge of the inner cover 113 are clamped in the clamp to limit the inner pot 101 and the inner cover 113 in the height direction D3 of the pressure cooker, thereby preventing the inner pot 101 and the inner cover 113 from disengaging from each other, thus ensuring that the cooking space can be pressurized. When the fastening element 131 is in the unlocked position, the clamp disengages from at least one of the edges of the inner pot 101 and the inner cover 113. Preferably, the fastening element 131 in the unlocked position disengages from the inner pot 101. The power source can be a drive motor 134. The drive motor 134 is driven to the fastener 131. The drive motor 134 is connected to a control unit to drive the fastener 131 to move between a locked position and an unlocked position under the control of the control unit.

[0090] See Figures 2 to 7Furthermore, the cover opening assembly 130 may also include a rotating frame 132. The rotating frame 132 is rotatably connected to the cover body 110 about a first axis AX1. The rotating frame 132 may include a guide hole 132a. The extension trajectory or extension direction of the guide hole 132a intersects the radial direction of the inner cover 113. The radial direction of the inner cover 113 intersects and is perpendicular to the first axis AX1. Correspondingly, the axial direction of the inner cover 113 is parallel to the first axis AX1. The extension trajectory may be a straight line, a curve, or a combination of both. The extension trajectory has at least a portion inclined to the radial direction of the inner cover 113, thereby enabling the drive fastener 131 to move in the radial direction of the inner cover 113. The fastener 131 is movably connected to the guide hole 132a. The rotating frame 132 is driveably connected to a drive motor 134. During the process of the drive motor 134 driving the rotating frame 132 to rotate, the fastening member 131 slides relative to the rotating frame 132 along the extension trajectory of the guide hole 132a, thereby enabling the drive fastening member 131 to move between the locked position and the unlocked position.

[0091] See Figures 3 to 7 Optionally, the fastening member 131 is connected to the guide hole 132a via a guide connector 137. The guide connector 137 may include fasteners such as screws or bolts. The guide connector 137 is connected to the fastening member 131. The guide connector 137 is located in the guide hole 132a and is movable relative to the guide hole 132a. During the rotation of the rotating frame 132, the fastening member 131 slides relative to the rotating frame 132 along the extension direction of the guide hole 132a through the sliding engagement of the guide connector 137 and the guide hole 132a, thereby causing the fastening member 131 to be driven by the rotating frame 132 to move in the radial direction of the inner cover 113.

[0092] See Figures 2 to 8 ,as well as Figure 11Furthermore, the cover-opening assembly 130 may also include a drive transmission assembly. The drive transmission assembly is connected between the rotating frame 132 and the motor shaft 134a of the drive motor 134 to transmit power that causes the rotating frame 132 to rotate. The drive transmission assembly includes a transmission connector 133. The transmission connector 133 has a rotation center portion 133a and a free end 133b. The rotation center portion 133a is rotatably connected to the cover 110 about a second axis AX2. The rotation center portion 133a is connected to the motor shaft 134a of the drive motor 134 to rotate synchronously with the motor shaft 134a. The free end 133b is movably connected to the rotating frame 132. The second axis AX2 is parallel to the first axis AX1. During the rotation of the motor shaft 134a of the drive motor 134, the transmission connector 133 rotates in the same direction as the motor shaft 134a of the drive motor 134. During the rotation of the motor shaft 134a of the drive motor 134, the rotation direction of the transmission connector 133 is opposite to the rotation direction of the rotating frame 132. For example... Figure 6 and Figure 7 As shown, the motor shaft 134a has a first rotation direction R1 and a second rotation direction R2. The first rotation direction R1 and the second rotation direction R2 are opposite. The first rotation direction R1 can be understood as counterclockwise. Correspondingly, the second rotation direction R2 can be understood as clockwise. During the rotation of the transmission connector 133 along the motor shaft 134a in the first rotation direction R1, the rotating frame 132 rotates in the second rotation direction R2, which is opposite to the first rotation direction R1, causing the fastening member 131 to move towards the locked position. During the rotation of the transmission connector 133 along the motor shaft 134a in the second rotation direction R2, the rotating frame 132 rotates in the first rotation direction R1, causing the fastening member 131 to move towards the unlocked position.

[0093] See Figure 3 , Figures 5 to 7 Optionally, the rotating frame 132 is provided with a trigger part 132c. The position detection device 140 includes a locking position detection device 141 corresponding to the locking position and an unlocking position detection device 142 corresponding to the unlocking position. The locking position detection device 141 is used to detect the locking position signal. The unlocking position detection device 142 is used to detect the unlocking position signal. The drive motor 134 can drive the transmission connecting member 133 to rotate along the second rotation direction R2 to the first limit position P1, thereby causing the rotating frame 132 to rotate to the first limit position P1. Figure 7The third extreme position is shown, which causes the fastener 131 to move to the unlocked position. When the rotating frame 132 rotates to the third extreme position, the trigger part 132c on the rotating frame 132 is detected by the unlocked position detection device 142, thereby generating an unlocked position signal and sending it to the control unit. The control unit determines that the fastener 131 is in the unlocked position based on the unlocked position signal. The drive motor 134 can drive the transmission connector 133 to rotate along the first rotation direction R1 to the second extreme position P2, thereby causing the rotating frame 132 to rotate to the third extreme position. Figure 6 The fourth extreme position, as shown, causes the fastener 131 to move to the locked position. When the rotating frame 132 rotates to the fourth extreme position, the trigger portion 132c on the rotating frame 132 is detected by the locking position detection device 141, thereby generating a locking position signal and sending it to the control unit. The control unit determines that the fastener 131 is in the locked position based on the locking position signal. The trigger portion 132c can be configured as a protrusion extending outward from the outer edge of the rotating frame 132 in the radial direction of the inner cover 113.

[0094] See Figure 5 and Figure 11 Furthermore, the rotating frame 132 has a transmission hole 132e. The transmission connector 133 also has a connecting shaft 133c. The connecting shaft 133c is inserted into the transmission hole 132e. The transmission hole 132e provides a clearance that allows the connecting shaft 133c to move radially relative to the rotating frame 132. For example, the transmission hole 132e can be configured as an elongated hole extending radially in a circle centered on the first axis AX1, to allow the connecting shaft 133c to move within the transmission hole 132e, thereby preventing jamming of the rotation of the rotating frame 132 and the rotation of the transmission connector 133. The transmission hole 132e can be a through hole or a blind hole. The transmission hole 132e is located at the edge of the rotating frame 132. While the connecting shaft 133c drives the rotating frame 132 to rotate, it can slide or move within the transmission hole 132e along its length.

[0095] It is understandable that in other examples, the positions of the transmission hole and the connecting shaft can be interchanged; that is, the transmission hole can be set in the transmission connector, and the connecting shaft can be set in the rotating frame.

[0096] See Figure 3 , Figures 5 to 7In addition, the rotating frame 132 also includes a drive boss 132d. The drive boss 132d has an engaged state that engages with the lid latch 160 and a disengaged state that is separated from the lid latch 160. In the engaged state, the drive boss 132d prevents external force from successfully pressing the lid opening button (not shown), thereby preventing the lid 110 from being opened. In the disengaged state, the drive boss 132d allows external force to successfully press the lid opening button, thereby allowing the lid 110 to be opened under the elastic force of the lid opening torsion spring 104. Specifically, when the lid 110 is closed on the pot body 100, when the rotating frame 132 rotates in the second rotation direction R2 (the motor shaft 134a rotates in the first rotation direction R1) to the fourth limit position, the fastener 131 moves to the locking position, and the drive boss 132d engages with the lid latch 160. With the lid 110 closed on the pot body 100, when the rotating frame 132 rotates along the first rotation direction R1 (the motor shaft 134a rotates in the second rotation direction R2) to the third extreme position, the fastening member 131 moves to the unlocked position, and the transmission boss 132d separates from the lid latch 160. It should be noted that the angle at which the rotating frame 132 rotates from the third extreme position to the fourth extreme position is less than or equal to the central angle corresponding to the circle centered on the first axis AX1 with the guide hole 132a. The central angle corresponding to the circle centered on the first axis AX1 with the transmission boss 132d can be less than or equal to the central angle corresponding to the guide hole 132a.

[0097] Regarding the switching of the cover opening assembly 130's state, to increase the selectable operation methods and meet the user's need for operational flexibility, this application also provides a technical solution for implementing manual operation. See below. Figures 9 to 13 as well as Figures 1 to 8 The following detailed description is provided in conjunction with some embodiments.

[0098] like Figures 9 to 13 As shown, according to this embodiment of the cooking appliance, the lid-opening assembly 130 includes a force-transmitting member 135. The cooking appliance also includes an operating member 138. The operating member 138 is disposed on the outside of the lid 110 so that it can be touched and operated by a user. The operating member 138 is arranged correspondingly to the force-transmitting member 135. The operating member 138 is throttlely connected to the force-transmitting member 135. The operating member 138 is configured to actuate the force-transmitting member 135 when operated, so that the lid-opening assembly 130 switches between a locked state and an unlocked state.

[0099] In use, the user applies force to the operating element 138, causing it to move. Simultaneously, the force applied to the operating element 138 is transmitted to the force transmission element 135, which in turn moves the force transmission element 135. While the force transmission element 135 moves, it transmits force to the cover opening assembly 130, ultimately enabling the cover opening assembly 130 to switch between a locked and unlocked state.

[0100] According to the cooking appliance of this application, the user can actuate the force transmission member 135 by applying an operating force to the operating member 138, thereby switching the lid locking and unlocking assembly 130 between a locked state and an unlocked state. Using the cooking appliance of this application allows the user to manually adjust the state of the lid locking and unlocking assembly 130 in cases of electrical control malfunctions, user need, or intentional manual control, thus meeting the user's need for operational flexibility and improving the user experience.

[0101] See Figures 9 to 11 In some examples, the operating element 138 is magnetically actuated to the force transmission element 135. During the movement of the operating element 138 by a force applied by the user, the operating element 138 transmits the force to the force transmission element 135 through magnetic attraction, causing the force transmission element 135 to move, thereby switching the state of the cover unlocking assembly 130. For example, switching the cover unlocking assembly 130 from a locked state to an unlocked state.

[0102] According to this application, by connecting the operating element 138 to the force transmission element 135 in a magnetic manner, contactless transmission between the operating element 138 and the force transmission element 135 can be achieved, which helps to reduce the structural complexity of the cover 110 and makes the cover 110 easier to manufacture.

[0103] Optionally, one of the operating element 138 and the force transmission element 135 includes a magnetic material. The other of the operating element 138 and the force transmission element 135 includes a magnetic conductor. It is understood that one of the operating element 138 and the force transmission element 135 may be partially or completely constructed as a magnetic material. Correspondingly, the other of the operating element 138 and the force transmission element 135 may be partially or completely constructed as a magnetic conductor. The magnetic material attracts the magnetic conductor through magnetic attraction. The magnetic material can be constructed as a permanent magnet made of materials such as magnetite. The magnetic conductor can be constructed as a structure made of materials such as steel or iron that can be attracted by magnetic force.

[0104] According to this application, by providing a magnetic body in one of the operating member 138 and the force transmission member 135 and a magnetic conductor in the other, a magnetic connection between the operating member 138 and the force transmission member 135 can be achieved.

[0105] Optionally, the operating element 138 and the force transmission element 135 each include a magnetic body.

[0106] According to this application, by providing magnetic bodies in both the operating member 138 and the force transmission member 135, a magnetic connection between the operating member 138 and the force transmission member 135 can be achieved, which helps to improve the magnetic attraction effect.

[0107] exist Figure 11 In the example shown, the operating element 138 is constructed as a magnetic body 138a.

[0108] See Figure 9 as well as Figure 12 and Figure 13 In other examples, the operating element 138 is fixedly connected to the force transmission element 135. This can be understood as either the operating element 138 being directly fixedly connected to the force transmission element 135, or the operating element 138 being indirectly fixedly connected to the force transmission element 135 through an intermediate structure. That is, the operating element 138 is rigidly connected to the force transmission element 135.

[0109] According to this application, by fixing the operating element 138 to the force transmission element 135, the operating element 138 and the force transmission element 135 can directly transmit force, thereby improving the efficiency and reliability of force transmission.

[0110] See Figures 9 to 13 Furthermore, a movement path indicator 111a3 is provided on the exterior of the cover 110. Specifically, the force transmission member 135 is located between the liner 112 and the face cover 111. The face cover body 111a of the face cover 111 is provided with the movement path indicator 111a3. The movement path indicator 111a3 is configured to correspond to the movement path of the force transmission member 135. The operating member 138 moves along the movement path indicator 111a3 to change the state of the cover locking / unlocking assembly 130.

[0111] According to this application, by providing a movement path indicator 111a3, it is convenient for the user to move the operation member 138 according to the indicated path of the movement path indicator 111a3, thereby helping to improve the accuracy of the user's operation.

[0112] like Figure 11 As shown, exemplarily, the movement path indicator 111a3 is configured as a guide groove. The guide groove may be a recessed groove structure formed from the outer surface of the cover 111.

[0113] According to this application, by configuring the movement path indicator 111a3 as a guide groove, the operating member 138 can be better positioned, further improving the accuracy of the operating member 138 when it is operated. This type of movement path indicator 111a3, with its guide groove, is more suitable for the embodiments of the magnetic drive method described above. By arranging the operating member 138 within the guide groove, the distance between the operating member 138 and the force transmission member 135 is reduced; the closer the distance, the stronger the magnetic force, thereby improving the force transmission effect. Furthermore, the guide groove can at least partially accommodate the operating member 138, thereby reducing the space occupied by the operating member 138.

[0114] like Figure 13 As shown, exemplarily, the movement path indicator 111a3 is configured as a guide hole. The guide hole may be a through hole provided through the faceplate 111. The guide hole allows the operating member 138 to pass through to connect to the force transmission member 135.

[0115] According to this application, by configuring the movement path indicator 111a3 as a guide hole, the operating member can be better positioned and guided, further improving the accuracy of the operating member when it is operated. Setting the movement path indicator as a guide hole is more suitable for the embodiment described above where the operating member 138 and the force transmission member 135 are fixedly connected.

[0116] See Figure 9 Furthermore, the cover 110 is provided with a movement direction indicator 111a4. Specifically, the movement direction indicator 111a4 can be provided on the outer surface of the cover 111. The movement direction indicator 111a4 is arranged correspondingly to the movement path indicator 111a3. Figure 9 In the diagram, the movement direction indicator 111a4 serves as a direction marker, with the arrow pointing in the direction used to switch the cover opening assembly 130 to the locked state. When the operating member 138 moves in this direction, the cover opening assembly 130 can be switched to the locked state. When the operating member 138 moves in the opposite direction, the cover opening assembly 130 can be switched to the unlocked state.

[0117] According to this application, by providing a movement direction indicator 111a4, it is easier for the user to identify the relationship between the movement direction of the operating component 138 and the state of the cover locking and opening assembly 130, thereby improving the accuracy and efficiency of the user's operation of the operating component 138.

[0118] See Figure 11 and Figure 13 as well as Figures 3 to 7 For example, the force transmission element 135 is connected to the rotating frame 132 and can be used to transmit power to the rotating frame 132.

[0119] According to this application, when the operating member 138 is operated by the user, the force is transmitted to the rotating frame 132 through the force transmission member 135, thereby driving the fastening member 131 to move between the locked position and the unlocked position through the rotation of the rotating frame 132, thereby achieving the purpose of manually changing the state of the cover opening assembly 130.

[0120] See Figure 11 and Figure 13 Optionally, the transmission connector 133 includes a force transmission element 135. The force transmission element 135 is located on the side of the second axis AX2 away from the free end 133b.

[0121] According to this application, the force transmission member 135 is part of the transmission connector 133. Here, the transmission connector 133 is used to transmit force between the operating member 138 and the rotating frame 132, so that when the operating member 138 is operated, the rotating frame 132 can be actuated, thereby driving the fastening member 131 to move, thus achieving the purpose of manually changing the state of the cover opening assembly 130. Since the force transmission member 135 is located on the side of the second axis AX2 away from the free end of the transmission connector 133, it is beneficial to reduce the space occupied by the force transmission member 135 between the second axis AX2 and the rotating frame 132, improving the rationality of the spatial layout and the flexibility of operation.

[0122] Optionally, the transmission connector 133 and the force transmission component 135 are fixedly connected. That is, the transmission connector 133 and the force transmission component 135 can be two originally independent parts, which are fixedly connected together by welding, riveting, locking or other methods.

[0123] Alternatively, the force transmission component 135 can be configured as a lever or other component.

[0124] See Figure 9 Optionally, in some examples, the drive motor 134 is located at the rear end of the cover 110. The drive motor 134 is connected to the aforementioned transmission connector 133 to drive the transmission connector 133 to rotate about the second axis AX2. Correspondingly, the operating member 138 is disposed on the upper part of the rear end of the cover 110. This facilitates operation and reduces interference with the hardware structure at the rotation axis AX and the space occupied at the rear end of the cover 110. The rear end of the cover 110 is the end closest to the rotation axis AX.

[0125] During the process of the drive motor 134 driving the rotating frame 132 to rotate, the operating component 138 will rotate together with the force transmission component 135.
