TECHNICAL FIELD

[0001] The present application relates to the technical field of refrigeration, in particular to a door body assembly of an embedded refrigeration device and the embedded refrigeration device. BACKGROUND

[0002] In today's society, the rapid progress of technology has greatly driven the transformation of home living styles. Among them, embedded furniture, as a design concept that integrates aesthetics and functionality, is favored by the majority of consumers. Embedded furniture cleverly integrates appliances or storage spaces into the home environment, not only effectively saving space, but also significantly improving the overall coordination and aesthetics of the home. Taking an embedded refrigerator as an example, this design enables the refrigerator to be seamlessly embedded in the cabinet, perfectly blending with the kitchen decoration style, creating a modern and harmonious living environment. However, although the embedded refrigerator exhibits significant advantages in improving the aesthetics and space utilization of the home, it still has a problem that cannot be ignored in actual use: the door is prone to interference or collision with the cabinet side wall during opening, resulting in poor user experience of the embedded refrigerator. SUMMARY

To this end, the present application proposes a door body assembly of a refrigeration device, which can control the gap on the opening side of the door body assembly while preventing interference.

[0004] The present application also proposes an embedded refrigeration device.

[0005] The door body assembly of the embedded refrigeration device according to the first aspect of the present application comprises:

[0006] a door, which is rotatably connected to a refrigeration cabinet, wherein the refrigeration cabinet is used to be embedded into a receiving space formed by the installation body;

[0007] a door panel, which is movably installed on the door, the door panel having a first interference site, the first interference site being located at the inner corner of the opening side of the door panel;

[0008] a controller configured to:

[0009] in the case that the width of the door panel is less than the critical width value, during the opening of the door, before the first interference site leaves the receiving space, the door panel starts to move towards the opening side of the door;

[0011] The critical width value is determined by structural parameters of the door panel and the cabinet door.

In addition, the different embodiments or examples described in the present specification and the features of the different embodiments or examples can be combined and combined by those skilled in the art without contradiction.

[0067] In today's society, the rapid progress of technology has greatly driven the transformation of home living styles. Among them, the embedded furniture, as a design concept that combines aesthetics and functionality in one, is favored by the majority of consumers. Embedded furniture cleverly integrates appliances or storage space into the home environment, not only effectively saving space, but also significantly improving the overall coordination and aesthetics of the home. Taking embedded refrigerators as an example, this design allows the refrigerator to seamlessly embed into the cabinet, perfectly blending with the kitchen decoration style, creating a modern and harmonious living environment. However, despite the significant advantages of embedded refrigerators in improving home aesthetics and space utilization, there is still a problem that cannot be ignored in the actual use process: the door body is prone to interference or collision with the cabinet side wall during opening, resulting in poor user experience of the embedded refrigerator.

[0068] Specifically, when the embedded refrigerator (referred to as refrigerator) meets the user's demand for both flat full-embedded and full-embedded refrigerators, the refrigerator door body (referred to as door body) after connecting with the cabinet door panel (referred to as door panel) will cause the entire door body assembly to thicken, resulting in that after the refrigerator is pushed into the accommodating space of the cabinet, only relying on the original single-axis or double-axis structure hinge of the refrigerator, the door body assembly with the cabinet door will interfere with the cabinet during opening and closing, resulting in that it cannot be normally opened and used. Therefore, the present application proposes a door body assembly that can make the door body and the door panel relatively slide, so that during the opening of the door body assembly, the door panel can slide towards the opening side (i.e. the opening side), so that during the opening process, the hinge side still maintains the thickness of the door body itself, consistent with the opening scene without the door panel. During the closing process, the door panel will move towards the hinge side to return to the state before opening; thereby realizing the refrigerator embedding installation demand with and without the door panel.

[0069] In order to be beautiful, the gap between the door panels of the same row of cabinets is usually in the range of 0mm-5mm, so the sliding mode and structure of the door panel relative to the cabinet door, due to the possibility of interference between the door panel and the cabinet panel on both sides at the initial stage of the door body being opened, need to be solved. Among them, with the opening of the cabinet door, the door panel moves relative to the cabinet door, if the displacement of the door panel corresponding to the opening of the cabinet door is too large, it will cause the door panel to interfere with the cabinet panel on the opening side in the case of small door panel width (the smaller the door panel width, the greater the angle of rotation required for the door panel to escape from the interference of the adjacent cabinet panel on the opening side), if the displacement corresponding to the angle is too small, it may cause the door panel to interfere with the cabinet panel on the hinge side. That is, for the same door panel gap, if the width of the door panel is different, the relative movement between the door panel and the cabinet door is also different in order to avoid interference of the door panel.

[0070] Based on this, the application provides a door body assembly of an embedded refrigeration equipment, referring to Figures 1 to 4 , comprising a cabinet door 2, a door panel 9 and a controller (not shown in the figure). Among them, the cabinet door 2 is rotatably connected to the refrigeration cabinet 1, and the refrigeration cabinet 1 is used to be embedded into the accommodating space formed by the installation body. The installation body generally refers to the cabinet 6 in this case, of course, the installation body can also be a wall corner, or the installation body can also refer to other components, as long as it can form an accommodating space, hereinafter the installation body is taken as the cabinet 6 for description. The door panel 9 is movably installed on the cabinet door 2, and the door panel 9 has a first interference position, which is located at the inner corner of the opening side of the door panel 9. The "inner" is relative to the refrigeration cabinet, the side facing the refrigeration cabinet 1 is the "inner" side, and the opposite side is the "outer" side. The controller can be installed on the door body cabinet door 2 or the door panel 9, of course, the controller can also be installed on the refrigeration cabinet 1. The controller is configured to: when the width of the door panel 9 is less than the critical width value, the door panel 9 starts to move towards the opening side of the cabinet door 2 before the first interference position leaves the accommodating space during the opening of the cabinet door 2; when the width of the door panel 9 is not less than the critical width value, the door panel 9 is stationary relative to the cabinet door 2 before the first interference position leaves the accommodating space, and the door panel 9 starts to move towards the opening side of the cabinet door 2 after the first interference position leaves the accommodating space; wherein the critical width value is determined by the structural parameters of the door panel 9 and the cabinet door 2.

[0071] According to the embodiment of the application, the cabinet door 2 is stationary before the first interference position leaves the accommodating space, which means that in this case, the distance between the door panel 9 and the side wall corresponding to the accommodating space can be zero when the cabinet door 2 is in the closed position, thereby realizing zero gap on the opening side of the door panel 9 assembly and ensuring the beauty of the embedded refrigeration equipment carrying such a door body assembly.

[0072] Figures 2 to 4 The position (indicated by the dotted line in the figure) and the angle relationship of the refrigerator when the door is initially opened and when the door is opened to any angle are simplified and marked in the figure. The corners that may interfere during the opening and closing of the door are marked with black dots. The C point represents the corner point of the left end of the door panel 9 close to the inside, which is the first interference point. The first interference point is the point where the end surface of the first cabinet panel 601 adjacent to the left side will interfere during the opening and closing of the door. The e point represents the corner point of the right end of the cabinet panel close to the outside, which is the critical point for the C point of the door panel 9 to escape interference during the opening and closing of the door. The situation of the critical point e for the C point to escape interference corresponds to the situation that the first interference point is about to leave the containing space, i.e., the situation that the C point of the first interference point is flush with the e point of the cabinet 6, i.e., the situation that the interference point C is located on the horizontal line where the e point is located. The d point represents the corner point of the right end of the door panel 9 close to the outside, which is the second interference point. It is the corner point where the right end surface of the door panel 9 first interferes with the left end surface of the second cabinet panel 602 adjacent to the right side during the opening and closing of the door. In combination with Figures 2 to 4 Since Figures 2 to 4 is a top view, the first interference point and the second interference point are a point from Figures 2 to 4 If the inside corner on the opening side is in an arc shape, the first interference point at this time is the point on the arc segment farthest from the hinge axis 101 of the door 2. Similarly, if the outside corner on the hinge side is in an arc shape, the second interference point at this time is the point on the arc segment farthest from the hinge axis 101 of the door 2.

[0073] According to the embodiments of the present application, for the case where the width of the door panel 9 is relatively large, i.e., not less than the critical width value, when the first interference point of the door panel 9 leaves the containing space, the opening angle of the door 2 at this time is still relatively small, so the hinge side of the door panel 9 will not interfere. Therefore, before the first interference point of the door panel 9 leaves the containing space, the door panel 9 can be stationary relative to the door 2 to ensure that neither side of the door panel 9 interferes with the cabinet 6. The critical width value can be 450mm to 550mm, for example, when the critical width value is 500mm, the width of the door panel 9 is in the range of 300mm to 500mm, at which time it is considered that the width of the door panel 9 is relatively small; when the width of the door panel 9 is in the range of 500mm to 800mm, it is considered that the width of the door panel 9 is relatively large. Similarly, when the critical width value is 510mm, it is considered that the width of the door panel 9 is relatively small when it is in the range of 300mm to 510mm; when the width of the door panel 9 is in the range of 510mm to 800mm, it is considered that the width of the door panel 9 is relatively large. Of course, the width of the door panel 9 is not limited to the range of 300mm to 800mm, but can also have other values.

[0074] In combination with Figures 2 to 4When the cabinet door 2 is in the closed position, the gap between the door panel 9 and the first cabinet panel 601 on the left side (i.e. the side wall of the accommodating space corresponding to the opening side of the door panel 9) is δ1, and the gap between the end surface of the hinge side of the door panel 9 and the cabinet panel on the right side (i.e. the side wall of the accommodating space corresponding to the hinge side of the door panel 9) is δ2. The hinge axis 101 of the hinge 10 of the cabinet door 2 is point O in the figure. l1 is the vertical distance from the hinge axis 101 of the cabinet door 2 to the inner surface of the door panel 9, l2 is the vertical distance from the hinge axis 101 of the cabinet door 2 to the end surface of the opening side of the door panel 9, l3 is the vertical distance from the hinge axis 101 of the cabinet door 2 to the end surface of the hinge side of the door panel 9, and h is the thickness of the cabinet door 2.

[0075] As can be seen from Figures 2 to 4 , in the initial position, the included angle between the oblique side OCo between point C and the hinge axis 101 on the left side and the inner side of the door panel 9 is θ0. The angle of the cabinet door 2 when it is opened to any position is Δθ0, and the oblique side OCo at this position and the distances l2 and l1 are indicated by black dashed lines. It is assumed that on the right side of the hinge axis 101, the distance l3 from the right end surface of the door panel 9 of different widths to the hinge axis 101 (i.e. point O) is constant.

[0076] When the width of the door panel 9 is increased to l21, it is assumed that the cabinet door 2 is opened to an angle of Δθ1, at which time the intersection point C1 of the horizontal line passing through the outer corner point e of the right end of the door panel 9 and point C, and the oblique side OC1 at this position and the distance l21 are indicated by blue dashed lines.

[0077] When the width of the door panel 9 is decreased to l22, it is assumed that the cabinet door 2 is opened to an angle of Δθ2, at which time the intersection point C2 of the horizontal line passing through the outer corner point e of the right end of the door panel 9 and point C, and the oblique side OC2 at this position and the distance l22 are indicated by red dashed lines.

[0078] On the right side of the hinge axis 101, the oblique side between point d and the hinge axis 101 is od, and when the cabinet door 2 is opened to an angle of Δθ at any position, the oblique side odx at this position and the distances l1+h and l3 are indicated by black dashed lines. As can be seen from Figures 2 to 4 , if the door panel 9 does not move towards the opening side of the cabinet door 2 during the opening of the cabinet door 2, dx point will soon interfere with the left end surface of the second cabinet panel 602 as the opening angle Δθ increases, resulting in the cabinet door 2 being unable to open. The horizontal distance between the dx point on the door panel 9 at this position and the right end surface of the door panel 9 in the initial position is λ, i.e. λ is the vertical distance by which the side wall of the accommodating space corresponding to the second interference position moves.

[0079] At the left side of the hinge shaft 101, the intersection points C1, C0 and C2 of the C point on the door panel 9 of different widths and the horizontal line passing the right end outer corner point e of the second cabinet panel 602 can be seen. The opening angles Δθ1, Δθ0 and Δθ2 corresponding to the intersection points C1, C0 and C2 can be seen. It can be seen that the larger the width of the door panel 9, the smaller the rotation angle of the C point on the door panel 9 from the right end outer corner point e of the adjacent first cabinet panel 601 at the left side during the opening and closing of the door. That is, the smaller the width of the door panel 9, the larger the rotation angle of the door panel 9 from the adjacent cabinet panel at the left side. According to the law, when the door panel 9 slides relative to the door body 2 to the opening side during the opening of the door, the total sliding distance Δs of the door panel 9 and the rotation angle Δθ of the door body 2 have a corresponding relationship. If the door panel 9 moves relative to the door body 2 from the initial position, the moving distance Δs of the door panel 9 increases with the increase of the opening angle Δθ. Therefore, when the width of the door panel 9 is too small, the angle of the C point on the door panel 9 from the interference is large, and the corresponding displacement Δs of the door panel 9 is large. However, the gap δ1 between the door panel 9 and the first cabinet panel 601 at the left side is constant. Therefore, when the width of the door panel 9 is small, the corresponding sliding mechanism (which will be described in detail below, connected between the door panel 9 and the door body 2, used to realize the movement of the door panel 9 relative to the door body 2) needs to be designed. The displacement Δs in the rotation initial range (for example, 0°-15°) should not be too large. If the displacement Δs is too small, the dx point on the door panel 9 at the hinge side will soon interfere with the second cabinet panel 602 at the right side.

[0080] Suppose that when the door body is opened by an angle of Δθ, the angle between the oblique side where the dx point and the hinge shaft 101 are located and the horizontal line in the drawing is β, and the angle between the oblique side where the C point and the hinge shaft 101 (i.e., the o point) are located and the horizontal line in the drawing is α. That is, β is the angle between the vertical line between the second interference position of the door panel 9 and the intersection point of the door body 2 and the width direction of the accommodation space, and α is the angle between the vertical line between the first interference position and the hinge shaft of the door body 2 when the first interference position is about to leave the accommodation space and the width direction of the accommodation space. The horizontal distance between the C point and the left end surface of the initial position of the door panel 9 is γ, that is, γ is the vertical distance of the first interference position moving towards the side wall of the corresponding accommodation space.

[0081] According to the embodiment of the present application, the critical width value can be obtained in the following manner. Specifically, the critical width value satisfies Δθ0=Δθx.

[0082] Δθ0 is calculated in the following manner:

[0083]

[0084] In combination with Figures 2 to 4, Δθ0 is the angle of the cabinet door 2 when the first interference position moves to the position about to leave the containing space in the case that the door panel 9 does not move relative to the cabinet door 2. Obviously, α can be obtained by .

[0085] Δθx is obtained by the following way:

[0086]

[0087] In the above, l1, l3, δ2 and h are all known as specific constants, and l2 is a variable value.

[0088] From δ2, the maximum rotation angle Δθx of the cabinet door 2 corresponding to the situation that the hinge side of the door panel 9 does not interfere with the second cabinet panel 602 in the case that the door panel 9 does not move relative to the cabinet door 2 in the initial position can be obtained.

[0089] Both Δθ0 and Δθx can be represented by a function of l2, and then l2 at this time, that is, the critical width value, can be obtained from Δθ0 = Δθx.

[0090] It is worth mentioning that the critical width value is not limited to being calculated by the above formula. In some cases, for example, a correction coefficient or a correction value is added in the above formula, which can also be used to calculate the critical width value. In addition, the above calculation formula is for the case where the hinge axis 101 is determined. If the cabinet door 2 is installed by using a double-axis hinge or a movable hinge, the hinge axis 101 will change with the opening of the cabinet door 2, and then the calculation formula of the critical width value is also adaptively changed, and the moving distance of the hinge axis 101 needs to be calculated in the formula. In addition, if there is an installation gap between the door panel 9 and the cabinet door 2, then h in the above calculation formula is the distance between the sliding surface of the door panel 9 and the outer surface of the door panel 9, and l1 is the distance from the hinge point of the cabinet door 2 to the sliding surface of the door panel 9.

[0091] According to the embodiment of the present application, the controller is configured to: in the case that the width of the door panel 9 satisfies Δθ0 ≥ Δθx, the width of the door panel 9 is smaller, and when the opening angle Δθ of the cabinet door 2 is less than Δθx, the door panel 9 is stationary relative to the cabinet door 2, and in the process of Δθ0 ≥ Δθ ≥ Δθx, the door body is controlled to move towards the opening side of the cabinet door 2.

[0092] In the process of the movement of the door panel 9 relative to the cabinet door 2, the moving distance Δs is ensured to be less than or equal to γ + δ1, so as to avoid the interference between the opening side of the door panel 9 and the first cabinet panel 601.

[0093] wherein,

[0094] Alternatively, in the process of the movement of the door panel 9 relative to the cabinet door 2, the moving distance Δs is ensured to be less than or equal to γ + δ1. To avoid interference between the opening side of the door panel 9 and the first cabinet panel 601.

[0095] The controller is further configured to: when the width of the door panel 9 satisfies the condition of Δθ0< Δθx, the width of the door panel 9 is larger, and when the opening angle of the cabinet door 2 reaches Δθx, the door body is controlled to move towards the opening side of the cabinet door 2, and before that, the door panel 9 can be stationary relative to the cabinet door 2 to ensure that the door panel 9 does not interfere with the cabinet 6. That is, before the first interference position leaves the containing space, the door panel 9 does not need to move towards the opening side of the cabinet door 2, and the hinge side of the door panel 9 can still be ensured not to interfere with the second cabinet panel 602.

[0096] During the movement of the door panel 9 relative to the cabinet door 2, it is ensured that β-l3, to ensure that the hinge side of the door panel 9 does not interfere with the second cabinet panel 602.

[0097] According to the embodiment of the present application, the critical width value is 450mm to 550mm.

[0098] According to the embodiment of the present application, the door panel 9 is movably installed on the cabinet door 2 through the sliding mechanism 4; the sliding mechanism 4 has an engaged state and a disengaged state, and the cabinet door 2 has a state switching angle; during the process that the cabinet door 2 is switched from the closed position to the state switching angle, the sliding mechanism 4 is in the disengaged state, and the door panel 9 is stationary relative to the cabinet door 2; during the process that the cabinet door 2 is switched from the state switching angle to the maximum opening angle, the sliding mechanism 4 is in the engaged state, and the sliding mechanism 4 drives the door panel 9 to move towards the opening side of the cabinet door 2.

[0099] According to the door body assembly of the embodiment of the present application, when the door panel 9 is initially opened at a small angle, the door panel 9 does not slide relative to the cabinet door 2, thereby avoiding interference on the opening side of the door panel 9. When the door panel 9 is rotated by a certain angle and does not interfere with the cabinet panels on both sides, the door panel 9 can slide relative to the cabinet door 2 by a larger displacement, thereby quickly avoiding the adjacent wood panels on the hinge side. The application scenarios of the door body assembly are more extensive, and the use is less limited, which is suitable for scenarios where the width of the door panel 9 is small or the displacement of the door panel 9 corresponding to each degree of opening angle is large.

[0100] The state switching angle can be set as Δθx mentioned above.

[0101] According to the door body assembly of the embodiment of the present application, the closing process is the reverse process of the opening process. Specifically, in the closing process, the sliding mechanism 4 is first in the combined state, and then the cabinet door 2 is closed to drive the door panel 9 to move towards the hinge side of the cabinet door 2. Until the opening angle of the cabinet door 2 corresponds to the state switching angle, the sliding mechanism 4 is in the disengaged state, at which time the door panel 9 has been reset, and then as the cabinet door 2 is further closed, the cabinet door no longer moves relative to the cabinet door 2. Because the door panel 9 is reset in advance, as the cabinet door 2 gradually approaches the closed position, the door panel 9 will not interfere with the cabinet 6.

[0102] According to the embodiment of the present application, the state switching angle ranges from 0° to 5°, for example, 4.15°. Corresponding to the state switching angle, the gap value between the door body assembly on both sides and the accommodation space in the closed position can be minimized to ensure the aesthetics and safety of the door body assembly. Among them, corresponding to the state switching angle, if the opening side of the door panel 9 has left the accommodation space, in this case, the gap between the opening side of the door body assembly in the closed position and the side wall of the accommodation space corresponding thereto (i.e. the cabinet panel of the cabinet 6) can be zero or close to zero.

[0103] The door panel 9 has an interference site, which is located at the outer corner of the hinge side of the door panel 9. If the outer corner of the door panel 9 has a curvature, the interference site is the vertical line farthest from the hinge axis of the cabinet door in the arc area at this time. Corresponding to the state switching angle, the distance between the interference site of the door panel 9 and the side wall of the accommodation space corresponding thereto (i.e. the cabinet panel corresponding to the interference site) is 0mm to 0.3mm. The cabinet door 2 is in the state switching angle, which corresponds to the situation that the hinge side of the door panel 9 and the cabinet panel are about to interfere. If the door panel 9 is still stationary relative to the cabinet door 2 at this time, as the cabinet door 2 is further opened, the door panel 9 will hit the cabinet panel. The ideal state is that the distance between the interference site and the side wall is exactly zero corresponding to the state switching angle, but in order to ensure safety, a certain safety margin can be reserved, and then as the cabinet door 2 is opened to the state switching angle, there is still a very small distance between the interference site of the door panel 9 and the cabinet panel.

[0104] Please refer to Figure 5 , in addition to the sliding mechanism 4 between the door panel 9 and the cabinet door 2, in order to ensure the stability of the movement of the door panel 9, a driven assembly 3 can also be provided. Figures 6 to 8 The driven assembly 3 includes a first track 301 and a first moving part 302 that can slide relative to the first track 301, Figure 6 In the first track 301 and the first moving part 302, the structure of the slide rail and the slide block can be adopted. Alternatively, referring to Figure 9The first track 301 can be in the form of a rack 406, and the first moving part 302 can be a gear 407 engaged with the rack 406. The specific structure of the first track 301 and the first moving part 302 is not limited here, as long as the first moving part 302 can move along the first track 301.

The connecting member 408 can be a steel wire, or it can also be other components that can realize power transmission between the second moving part 403 and the third moving part 404.

[0106] Of course, the specific structure of the sliding mechanism 4 is not limited by the examples here, as long as the traction mechanism 5 can drive the sliding mechanism 4 to move when the door panel 9 moves relative to the cabinet door 2. For example, the sliding mechanism 4 can be the structure of the double sliding rail and the sliding block mentioned above, or it can also adopt the structure of the gear 407 and the rack 406, etc., please refer to Figure 9 The sliding mechanism 4 includes a gear 407 and a rack 406, which are driven to move by rotating the gear 407, wherein the gear 407 is connected with the output shaft of the traction mechanism 5, and the rack 406 is fixedly connected with the door panel 9.

[0107] According to the embodiments of the present application, in combination with Figure 6, the traction mechanism 5 comprises a pull rod 501 and a motor, the first end of the pull rod 501 is rotationally connected to the second moving part 403, and the second end of the pull rod 501 is rotationally connected to the cabinet door 2.

Further, through the cooperation between the first pin shaft 502 and the first long hole, the door panel 9 is delayed to move when the door is opened. Alternatively, one of the second end of the pull rod 501 and the cabinet door 2 is provided with a second pin shaft 503, and the other is provided with a second long hole (not marked in the figure). Further, through the cooperation between the second pin shaft 503 and the second long hole, when the cabinet door 2 is just opened, the second pin shaft 503 and the second long hole cannot realize motion transmission at this time, until the second pin shaft 503 contacts the side wall of the second long hole, at which time the motion of the traction mechanism 5 is transmitted to the sliding mechanism 4, thereby driving the door panel 9 to move relative to the cabinet door 2. On the basis of the above, the motor power is coupled to the first end of the pull rod 501 to drive the rotation of the pull rod 501.

[0108] In addition to the structure of the above long hole (i.e. the first long hole or the second long hole) and the pin shaft, a limiting part can also be provided on the third moving part 404. Further, in the disengaged state, the limiting part and the door panel 9 are spaced apart, and in the engaged state, the door panel 9 and the limiting part abut. In combination Figure 6 , the third moving part 404 is provided with a notch 303, the limiting part is the end side wall of the sliding groove, and the third moving part 404 further comprises a hook 304, which is hung on the notch 303.

Further, as the traction mechanism 5 drives the second moving part 403 to move, the third moving part 404 moves with the door panel 9 relative to the cabinet door 2. Above, the opening width of the notch 303 is greater than the width of the hook 304, so as to ensure that in the disengaged state, the hook 304 and the side wall of the notch 303 do not contact.

For example, a tensioning part can be provided, and the state of the sliding mechanism 4 is switched by switching the position of the tensioning part, so that before the flexible cable is tensioned, the motion of the second moving part 403 cannot be transmitted to the third moving part 404, and when the flexible cable is tensioned, the traction mechanism 5 can drive the third moving part 404 to move through the second moving part 403, thereby driving the door panel 9 to move.

[0110] In yet another embodiment, please refer to Figure 11The traction mechanism 5 comprises an arc-shaped gear 504 and a motor. The arc-shaped gear 504 has a tooth portion. The second moving part 403 is provided with a rack 406. In the engagement state, the rack 406 and the tooth portion are engaged.
