[0038] Embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0039] Reference below Figure 1-Figure 14 An air supply assembly 100 and an air conditioner according to an embodiment of the present invention are described.

[0040] like Figure 1 and Figure 2 As shown, the air supply assembly 100 according to the first embodiment of the present application includes: a power module 10 and an air guide module 20, the power module 10 is used to output power, and the air guide module 20 can adjust the angle to achieve air supply.

[0041] Among them, the power module 10 has a power input terminal 11, a first power output terminal 12 and a second power output terminal 13, and the wind guide module 20 includes: a first wind guide component 21 and a second wind guide component 22, the first wind guide component 21 is power-connected to the first power output terminal 12, the second wind guide component 22 is power-connected to the second power output terminal 13, the power input terminal 11 is power-connected to the first power output terminal 12, and the first power output terminal 12 is selectively power-connected to the second power output terminal 13, so that the first wind guide component 21 and the second wind guide component 22 guide the wind in the same direction or in different directions.

[0042] For example, see Figure 3 , Figure 4 and Figure 5 As shown, at this time, the first air guide component 21 and the second air guide component 22 can achieve the same air guide, such as Figure 6 and Figure 7As shown, at this time, the first air guide component 21 and the second air guide component 22 can achieve different wind guidance and same wind guidance, and correspondingly can achieve conventional air supply and conventional air sweeping, that is, the first air guide component 21 and the second air guide component 22 swing in the same direction, or after swinging in the same direction to a position, stop at the same time to achieve preset angle air supply, different wind guidance, and correspondingly can achieve centralized air supply, centralized air sweeping, partitioned air supply and partitioned air sweeping, that is, the first air guide component 21 and the second air guide component 22 move away from each other, and at this time, partitioned air supply can be achieved (such as: the first air guide component 21 and the second air guide component 22 are symmetrically arranged in the left and right directions, the first air guide component 21 is located on the left and supplies air to the left, and the second air guide component 22 is located on the right and supplies air to the right), the first air guide component 21 and the second air guide component 22 move toward each other, and at this time, centralized air supply can be achieved (that is: the first air guide component 21 and the second air guide component 22 are symmetrically arranged in the left and right directions, the first air guide component 21 is located on the left and supplies air to the right, and the second air guide component 22 is located on the right and supplies air to the left, so that the airflow is directed toward the middle).

[0043] Specifically, the first power output end 12 can drive the first air guide component 21 to move, the second power output end 13 can drive the second air guide component 22 to move, and the power input end 11 drives the first power output end 12, so that the first air guide component 21 can reciprocate within an angle range (such as: a fan-shaped area) or a position range (from the first position to the second position on a straight line), the first power output end 12 selectively drives the second power output end 13, and the second power output end 13 drives the second air guide component 22 to reciprocate within an angle range or a position range, and the angle range or position range of the first air guide component 21 is consistent with the angle range or position range of the second air guide component 22, but the first air guide component 21 and the second air guide component 22 are set at different positions.

[0044] Furthermore, the first air guide component 21 always reciprocates within an angle range or position range, and the second air guide component 22 moves within an angle range or position range only when the first power output end 12 is connected to the second power output end 13, so that the air outlet angle of the first air guide component 21 can be consistent with the air outlet direction of the second air guide component 22 through the intermittent power output of the second power output end 13 (such as Figure 3 , Figure 4 and Figure 5 As shown), to achieve the same direction of wind, or the wind outlet angle of the first wind guide component 21 is different from the wind outlet direction of the second wind guide component 22, to achieve different directions of wind (such as Figure 6 and Figure 7 shown).

[0045] Exemplarily, the first air guide component 21 and the second air guide component 22 are symmetrically arranged in the left and right directions, and the first air guide component 21 is located on the left and the second air guide component 22 is located on the right. The first power output terminal 12 is driven by the power input terminal 11, and the second power output terminal 13 can selectively drive the second power output terminal 13, so that when the first air guide component 21 and the second air guide component 22 discharge air in the same direction, the conventional air sweeping of the air supply component 100 can be realized. When the first air guide component 21 and the second air guide component 22 supply air in different directions, the first air guide component 21 to the left and the second air guide component 22 to the right can realize zoned air supply, and swing synchronously to realize zoned air sweeping. The first air guide component 21 to the right and the second air guide component 22 to the left can realize centralized air supply, and swing synchronously to realize centralized air sweeping, so that the air supply component 100 of the embodiment of the present application has multiple air supply modes, rich air supply modes, and good user experience.

[0046] It is understandable that the existing air supply structure that can achieve centralized air supply and partitioned air supply requires the use of multiple power modules 10 to drive two or more air guide components respectively, and the structure is complex and the cost is high. However, the present application can achieve the differential of the second air guide component 22 through the selectable power connection between the first power output terminal 12 and the second power output terminal 13, so that the air outlet angles of the first air guide component 21 and the second air guide component 22 can be in the same direction or in different directions. There is no need to set up multiple power modules 10, which can simplify the structure and reduce costs.

[0047] It should be pointed out that the first power output terminal 12 and the second power output terminal 13 are intermittently connected with each other. When the power transmission between the first power output terminal 12 and the second power output terminal 13 is interrupted, the second power output terminal 12 and the second air guide component 22 may continue to move under the action of inertia. After continuing to move, the air guide angle of the second air guide component 22 will deviate. In the subsequent air guide cycle process, the first air guide component 21 and the second air guide component 22 may be out of sync in guidance and movement. At the same time, the second power output terminal 13 may further move under the action of power and move to the dead point of movement, resulting in the first power output terminal 12 being unable to resume power transmission with the second power output terminal 13, thereby causing the air supply component 100 to crash.

[0048] Based on this, the present application further sets up a first limiting component, which has a first limiting portion 41 and a second limiting portion 42. The first limiting portion 41 is arranged at the first power output terminal 12, and the second limiting portion 42 is arranged at the second power output terminal 13. The first limiting component 41 is suitable for cooperating when the power connection between the first power output terminal 12 and the second power output terminal 13 is interrupted to limit the second power output terminal 13.

[0049] According to the air supply component 100 of the embodiment of the present application, by setting a first power output module and a second power output module with selectable power connection, the differential of the first air guide component 21 and the second air guide component 22 is realized, so as to adjust the air outlet angles of the first air guide component 21 and the second air guide component 22 to be the same or different, so as to realize zoned air supply and centralized air supply, and after the air outlet angle adjustment is completed, the first air guide component 21 and the second air guide component 22 can swing synchronously, so as to realize conventional air sweeping, zoned air sweeping and centralized air sweeping, enrich the air outlet mode, and improve the user experience, more importantly, after the second power output terminal 13 is limited by the first limiting component, the second air guide component 22 can be prevented from being misaligned when the power of the second power output terminal 13 is interrupted, so that the first air guide component 21 and the second air guide component 22 can move according to the expected operating trajectory, and the second power output terminal 13 can be prevented from moving to the power dead point, thereby improving the working stability and reliability of the air supply component 100 and improving the user experience.

[0050] It should be pointed out that the differential movement of the first air guide component 21 and the second air guide component 22 means that after the first air guide component 21 rotates to the first angle, the second air guide component 22 is connected to power, and after the second air guide component 22 is connected to power, the angle of the second air guide component 22 is adjusted. When the air outlet angles of the two are adjusted to be consistent and both are connected to power, the power output end continuously outputs power to achieve conventional wind sweeping. When the air outlet angles of the two are adjusted to be in different directions and power is connected, the power output end continuously outputs power to achieve centralized wind sweeping or partitioned wind sweeping. It should be pointed out that centralized air supply and partitioned air supply mean that the air outlet angles of the first air guide component 21 and the second air guide component 22 remain unchanged, that is, after the air outlet angles of the first air guide component 21 and the second air guide component 22 are adjusted, the power module 10 stops power output so that the airflow flows out at a fixed angle. Centralized air sweeping and partitioned air sweeping mean that after the air outlet angle adjustment is completed, the power module 10 continuously outputs power (such as the drive motor of the power module 10 swings within an angle range, continuously rotates, etc.).

[0051] like Fig.10 and Fig.11 As shown, according to some embodiments of the present application, the first power output end 12 includes a first output gear 121, and the second power output end 13 includes a second output gear 131, and the first output gear 121 is formed as an incomplete gear so that the first output gear 121 and the second output gear 131 are selectively engaged.

[0052] Exemplarily, the power input end 11 is constructed as a driving motor, and the first output gear 121 is sleeved on the motor shaft of the driving motor, or the first output gear 121 is meshed with the driving gear of the driving motor, such as: the motor shaft and the first output gear 121 are coaxially arranged to drive the first output gear 121 to rotate, and the rotation of the first output gear 121 can drive the first air guide component 21 to adjust the air outlet angle of the first air guide component 21, and when the smooth section of the first output gear 121 is in contact with or opposite to the second output gear 131, the second output gear 131 is stationary, so that the air outlet angle of the second air guide component 22 remains unchanged, and when the meshing tooth section of the first output gear 121 is meshed with the second output gear 131, the second output gear 131 rotates to adjust the air outlet angle of the second air guide component 22. Through the setting of the smooth section, the air outlet angle adjustment of the first air guide component 21 and the air outlet angle adjustment of the second air guide component 22 can be differentially realized, so as to realize the same-direction air outlet and the opposite-direction air outlet of the two, thereby improving the working stability and reliability of the power module 10.

[0053] Of course, the structure of the present application for achieving the differential movement of the first air guide component 21 and the second air guide component 22 is not limited to this. In other embodiments, the first power output terminal 12 can be formed as a cam, and the second power output terminal 13 can be formed as a slider. The cam pushes the slider so that the second power output terminal 13 can achieve a differential movement with the first power output terminal 12.

[0054] like Fig.10 and Fig.11 As shown, according to some embodiments of the present application, the pitch circle diameters of the first output gear 121 and the second output gear 131 are equal, and the gear ratio of the first output gear 121 to the second output gear 131 is 1:2.

[0055] In this way, it can be ensured that the linear speed of the first air guide component 21 driven by the first output gear 121 to swing is consistent with the linear speed of the second air guide component 22 driven by the second output gear 131 to swing, so that in the conventional wind sweeping mode, centralized wind sweeping mode and partitioned wind sweeping mode driven by the power module 10, the first air guide component 21 and the second air guide component 22 have higher synchronization, and the air supply component 100 has higher working stability and more reliable operation.

[0056] See also Fig.10 and Fig.11As shown, the first limiting portion 41 is constructed as an arc-shaped limiting convex portion, and the second limiting portion 42 is constructed as an arc-shaped limiting concave portion. The arc-shaped limiting convex portion and the arc-shaped limiting concave portion are matched in a concave-convex manner so that the convex surface of the arc-shaped limiting convex portion contacts the concave surface of the arc-shaped limiting concave portion to achieve the limitation of the second output gear 131. By limiting the second output gear 131, the second power output end 13 cannot rotate, and correspondingly the second air guide assembly 22 can be maintained at the current opening angle, the current opening position or the current closing position. The concave-convex matching limitation of the first limiting portion 41 and the second limiting portion 42 are respectively arranged on the end faces of the first output gear 121 and the second output gear 131. The setting position is reasonable and can be integrally formed or connected by a connecting shaft. The structure is simple, the cost is low, and the limitation is reliable and stable.

[0057] Further, it can be understood that when the smooth tooth segment of the first output gear 121 is opposite to the second output gear 131, the first output gear 121 and the second output gear 131 are in a non-meshing state, and the arc surface angle of the arc-shaped limiting protrusion is the same as the arc surface angle of the smooth tooth segment. For example, if the arc surface angle of the smooth tooth segment is 180°, then the arc surface scale of the arc-shaped limiting protrusion is correspondingly 180°. Correspondingly, the arc-shaped limiting recess is correspondingly arranged at the starting point and end point of the meshing of the meshing tooth segment of the second output gear 131 and the first output gear 121, and the arc surface angle of the arc-shaped limiting recess can be 3°, 5°, 15°, etc., and the arc surface angle of the arc-shaped limiting recess does not need to be specifically limited.

[0058] Of course, the first limiting component of the embodiment of the present application is not limited thereto. In other embodiments, the first limiting portion 41 may be constructed as an arc-shaped limiting concave portion, and the second limiting portion 42 may be constructed as an arc-shaped limiting convex portion.

[0059] See also Figure 1 , Figure 8 and Fig. 9 In the embodiment shown, the first power output end 12 also includes a first connecting rod 122, which is connected to the first output gear 121, and the first connecting rod 122 is dynamically connected to the first wind guide assembly 21. The second power output end 13 also includes a second connecting rod 132, which is connected to the second output gear 131, and the second connecting rod 132 is dynamically connected to the second wind guide assembly 22. The extension directions of the first connecting rod 122 and the second connecting rod 132 are opposite.

[0060] Among them, the air supply assembly 100 also includes a shell 30, the first output gear 121, the second output gear 131 and the drive motor are all arranged in the shell 30, the first connecting rod 122 and the second connecting rod 132 are outside the shell 30, and are respectively connected to the first output gear 121 and the second output gear 131.

[0061] That is to say, the installation directions of the first connecting rod 122 and the second connecting rod 132 are opposite, so that the first output gear 121 and the second output gear 131 with different rotation angles after engagement can respectively drive the first air guide component 21 and the second air guide component 22 located on the same side of the air outlet to move, thereby further improving the working stability and reliability of the air supply component 100.

[0062] Preferably, the extension direction of the first connecting rod 122 is parallel to the diameter line where the starting point or end point of the meshing tooth segment of the first output gear 121 is located. Therefore, for every rotation of the first output gear 121, the second output gear 131 rotates half a circle, the movement stroke of the first connecting rod 122 and the first air guide component 21, and the movement stroke of the second connecting rod 132 and the second air guide component 22 are consistent, and the differential form of every rotation of the first output gear 121 and the second output gear 131 half a circle makes it easier and more convenient to adjust the air outlet angles of the first air guide component 21 and the second air guide component 22, with lower adjustment difficulty and higher synchronization.

[0063] See also Figure 8 and Fig.12 As shown, according to some embodiments of the present application, the wind guide module 20 also includes: a mounting plate 23, the first wind guide component 21 includes: a plurality of first blades 211 and a first blade connecting rod 212, the first blade connecting rod 212 is power-connected to the first power output terminal 12, the first blade 211 is connected to the first blade connecting rod 212, and is suitable for rotating relative to the mounting plate 23 under the drive of the first blade connecting rod 212, the second wind guide component 22 includes: a plurality of second blades 222 and a second blade connecting rod 221, the second blade connecting rod 221 is power-connected to the second power output terminal 13, the second blade 222 is connected to the second blade connecting rod 221, and is suitable for rotating relative to the mounting plate 23 under the drive of the second blade connecting rod 221.

[0064] Specifically, a first guide groove is provided on the first blade link 212, and the first link 122 extends into the first guide groove and pulls or pushes the first blade link 212 in the first guide groove, and the first blade link 212 drives the first blade 211 to rotate relative to the mounting plate 23. A second guide groove is provided on the second blade link 221, and the second link 132 extends into the second guide groove and pulls or pushes the second blade link 221 in the second guide groove, and the second blade link 221 drives the second blade 222 to rotate relative to the mounting plate 23.

[0065] See also Fig.12As shown, the first blade 211 and the second blade 222 both include: a blade body 101, a connecting portion 102 located at the end of the blade body 101, and a pivot portion 103 located between the blade body 101 and the connecting portion 102, the pivot portion 103 is pivotally connected to the mounting plate 23, and the connecting portion 102 is connected to the first blade link 212 or the second blade link 221.

[0066] Therefore, the first blade 211 and the second blade 222 can both use the pivot part 103 as the rotation axis, and the first blade link 212 or the second blade link 221 pushes the connecting part 102 so that the blade body 101 can rotate around the rotation axis to achieve swing relative to the mounting plate 23, and can improve the rotation stability and reliability of the first blade 211 and the second blade 222.

[0067] Combination Figure 3-Figure 7 as well as Fig.13 As shown, several air supply modes and air sweeping modes of the air outlet assembly of the embodiment of the present application are specifically described.

[0068] First, the air supply modes of the air supply component 100 of the present application include: conventional air supply mode, centralized air supply mode and zoned air supply mode; the air sweeping modes include: conventional air sweeping mode, centralized air sweeping mode and zoned air sweeping mode.

[0069] In the conventional air supply mode, the angles of the first blade 211 and the second blade 222 can be Figure 3 , Figure 4 or Figure 5 In the zoned air supply mode, the angles of the first blade 211 and the second blade 222 can be Figure 6 In the centralized air supply mode, the angle of the first blade 211 and the angle of the second blade 222 can be Figure 7 Angle shown.

[0070] In the conventional wind sweeping mode, the angle of the first blade 211 and the angle of the second blade 222 can be Figure 3 to Figure 5 The angles shown in the figure can be changed continuously to realize the conventional wind sweeping. In the zone wind sweeping mode, the angles of the first blade 211 and the second blade 222 can be Figure 3 and Figure 6 The angles shown in the figure can be changed continuously to realize the zoned wind sweeping. In the concentrated wind sweeping mode, the angles of the first blade 211 and the second blade 222 can be Figure 3 and Figure 7 Continuous variation between the angles shown to achieve concentrated wind sweeping.

[0071] See also Fig.13 As shown, the angle adjustment of the first blade 211 and the second blade 222 is specifically as follows:

When the power module 10 drives the first output gear 121 to rotate clockwise, the second output gear 131 rotates counterclockwise, and the first connecting rod 122 and the second connecting rod 132 drive the first blade 211 and the second blade 222 to swing left and right respectively.

That is, when rotating 270°, the centralized air supply mode is realized, such as Figure 7 shown.

When the first output gear 121 rotates to 360°, the state is as follows: Fig.13 As shown in FIG. 5 , at this time, the first blade 211 and the second blade 222 are both reset to the initial state, that is, 270° to 360°. This stage is the centralized air supply mode, and the centralized air supply angle is adjustable.

[0076] 5. The power module 10 drives the first output gear 121 to continue to rotate clockwise, the first output gear 121 meshes with the second output gear 131, the first connecting rod 122 drives the first blade connecting rod 212 to move leftward, and then the first blade 211 rotates rightward, the second connecting rod 132 drives the second blade connecting rod 221 to move rightward, and then drives the second blade 222 to rotate leftward.

Figure 6 That is, 360°~450°, this stage is the zone air supply mode, and the zone air supply angle is adjustable.

[0077] 6. The driving force module 10 drives the first output gear 121 to continue to rotate clockwise. The first output gear 121 is not meshed with the second output gear 131. The second blade 222 maintains an unchanged angle. The first connecting rod 122 drives the first blade connecting rod 212 to move rightward, thereby driving the first blade 211 to rotate leftward. When the first output gear 121 rotates to 540°, the state is as follows: Fig.13 As shown in FIG. 6 , at this time, the first air guide component 21 is reset to the initial state, and the second blade 222 of the second air guide component 22 is in the maximum position of supplying air to the left.

The second blade 222 maintains an unchanged angle. The first connecting rod 122 drives the first blade connecting rod 212 to move rightward, thereby driving the first blade 211 to rotate leftward.

Figure 4 That is, when it is rotated to 630°, the left swing air supply mode is realized.

[0079] 8. The power module 10 drives the first output gear 121 to continue to rotate clockwise, the first output gear 121 meshes with the second output gear 131, the first connecting rod 122 drives the first blade connecting rod 212 to move leftward, and then the first blade 211 rotates rightward, the second connecting rod 132 drives the second blade connecting rod 221 to move rightward, and then drives the second blade 222 to rotate leftward. When the first output gear 121 rotates to 720°, the first air guide assembly 21 and the second air guide assembly 22 are reset to the initial state, that is, Fig.11 0° state in a.

[0080] In summary, taking clockwise as positive, different air supply modes are summarized as follows:

[0081] When the first output gear 121 rotates from -90° to 90°, this stage is a conventional air sweeping mode, and when it stays at any angle from -90° to 90°, a conventional air supply mode with a fixed angle can be achieved;

[0082] When the first output gear 121 rotates from 270° to 360°, this stage is a concentrated air sweeping mode. When it stops at any angle of 270° to 360°, it can achieve concentrated air supply at a fixed angle;

[0083] When the first output gear 121 rotates at 360° to 450°, this stage is a zoned wind sweeping mode. When it stops at any angle of 360° to 450°, a zoned wind sweeping mode with a fixed angle can be realized;

[0084] Other angles are transition modes, which play an automatic transition role when the user sets several modes. According to the user's air supply mode and the air supply mode selection, the first output gear 121 switches with each other at the corresponding angle, so as to realize the switching of different air supply modes and different air sweeping modes, and meet the different needs of users.

[0085] In summary, it should be pointed out that the first air guide component 21 and the second air guide component 22 need to cycle multiple times in multiple air supply modes during the working cycle. If the zeroing operation is not performed for a long time, the running trajectory of the air guide component may be disordered, resulting in disordered air output and affecting the user experience.

[0086] Based on this, the present application further sets a second limit assembly, which includes a limit pawl 51 and a limit ratchet 52. The limit ratchet 52 is arranged at the first power output end 12, and the side of the limit ratchet 52 has a limit groove 521. The limit pawl 51 pushes against the limit ratchet 52 and can selectively extend into the limit groove 521 to limit the rotation angle of the power input end 11 to a limited angle. The power input end 11 is constructed to rotate to an initial angle, and the interval between the limited angle and the initial angle is 180°. At the initial angle and the limited angle, the line connecting the centers of the first output gear 121 and the second output gear 131 is perpendicular to the line connecting the midpoint of the meshing tooth segment of the first output gear 121 and the center of the first output gear 121.

[0087] See also Fig.13 As shown, at the initial angle, the angular positions of the first output gear 121 and the second output gear 131 are Fig.13 The positions of the first output gear 121 and the second output gear 131 are consistent with each other in the d state and the h state, and under the limit angle, the angular positions of the first output gear 121 and the second output gear 131 are consistent with each other in the d state and the h state. Fig.13The positions in states b and f are consistent, that is, the cooperation between the limit pawl 51 and the limit ratchet 52 can realize the zeroing action of one rotation within the range of -90° to 90° or 90° to -90°. In the process of completing the zeroing action, the rotation angle of the first air guide component 21 and the second air guide component 22 can be corrected, that is, the first output gear 121 is limited by the second limit component to stop at a limited angle. If there is an offset in the rotation trajectory of the first air guide component 21 and the second air guide component 22, they can be reset under inertia during the process of the first output gear 121 being limited. After the reset is completed, it rotates to the initial position to complete the zeroing.

[0088] In this way, the swing angle of the air guide component can be corrected, so that the synchronization between the first air guide component 21 and the second air guide component 22 is better, so as to improve the air outlet effect, improve the air outlet turbulence, and enhance the user experience.

[0089] Furthermore, the limiting pawl 51 is located at the starting point or end point of the smooth tooth segment of the first output gear 121 , and the corresponding limiting groove 521 is located at the midpoint of the arc surface of the meshing tooth segment of the first output gear 121 or the midpoint of the arc surface of the smooth tooth segment.

[0090] In other words, Fig.13 When the 90° in the middle b state is used as the limiting angle, the limiting pawl 51 is located at the starting point of the smooth tooth segment of the first output gear 121, and the corresponding limiting groove 521 is located at the midpoint of the arc surface of the meshing tooth segment of the first output gear 121. Fig.13 When the same rotation angle of -90° in the middle d state is used as the limiting angle, the limiting pawl 51 is located at the end point of the smooth tooth segment of the first output gear 121 , and the corresponding limiting groove 521 is located at the midpoint of the arc surface of the smooth tooth segment of the first output gear 121 .

[0091] Correspondingly, when the limit angle is at 90°, the air supply mode is selected by rotating counterclockwise, and when the limit angle is at -90°, the air supply mode is selected by rotating clockwise.

[0092] like Fig.14 As shown, the limiting pawl 51 is rotatably disposed on the first output gear 121 or the housing 30 of the power module, and the second limiting assembly further includes: a driving member 53, which is used to drive the limiting pawl 51 to push against the side of the limiting ratchet 52 so as to selectively extend into the limiting groove 521.

[0093] Therefore, the limiting pawl 51 is driven by the driving member 53 to stop in the limiting groove 521 to achieve the zeroing action, thereby improving the stability and reliability of the zeroing action.

[0094] In some embodiments, the driving member 53 is configured as an elastic member, and the elastic member is configured to push against the limiting pawl 51 along the circumferential direction of the limiting pawl 51 or push against the limiting pawl 51 along the radial direction of the limiting pawl 51 .

[0095] That is to say, in some embodiments, the elastic member is constructed as a torsion spring and is coaxially arranged with the limit pawl 51. One end of the torsion spring pushes the limit pawl 51, and the other end pushes against the first output gear 131 or the housing 30. In other embodiments, the elastic member is constructed as a linear spring, a mounting block can be provided on the housing 30, and a positioning column can be provided on the side wall of the housing 30. One end of the linear spring pushes against the limit pawl 51, and the other end pushes against the side wall of the housing 30. A positioning column can also be provided on the limit pawl 51. The end of the linear spring is arranged in the positioning column, and a limit column can also be provided on the mounting block. The limit column is located on the side surface of the limit pawl 51 away from the limit ratchet 52, and is suitable for pushing the limit pawl 51 to avoid the limit pawl 51 from transitioning to the housing 30, thereby improving the working stability of the second limit assembly.

[0096] Of course, the structure of the driving member 53 in the embodiment of the present application is not limited thereto. In other embodiments, such as Fig.14 As shown, the driving member 53 can be constructed as a magnetic attraction member, the limiting pawl 51 is constructed as a magnetically adsorbable member, and the driving member 53 is arranged adjacent to the limiting groove 521 to achieve limiting cooperation of the second limiting component through magnetic attraction.
