Description

Technical Field

[0001] At least one embodiment of the present disclosure relates to the technical field of supporting devices, and in particular, to a supporting device for supporting an external electronic device. Background Art

[0002] Tablet computers are often used with keyboards to replace traditional notebook computers. In this scenario, a certain support method is needed to keep the tablet at a certain angle to the desktop (generally >120°) and prevent it from tipping over during use.

[0003] Traditional laptops rely mainly on damping shafts to provide support, but this approach is not entirely suitable for tablet products. The reason is that most of the weight of traditional laptops is distributed on the base with the keyboard, while the screen is relatively light, and the base is heavier than the screen, so it is not easy to tip over. In contrast, in the combination of a tablet and a keyboard, the weight of the tablet is greater than the keyboard, and during use, the screen may be tapped, so it is easy to tip over. Summary of the invention

[0004] In view of this, the present disclosure provides a supporting device capable of increasing stability.

[0074] In order to make the objectives, technical solutions and advantages of the present disclosure more clearly understood, the present disclosure is further described in detail below in combination with specific embodiments and with reference to the accompanying drawings.

[0075] The terms used herein are only for describing specific embodiments and are not intended to limit the present disclosure. The terms "comprise", "include", etc. used herein indicate the existence of the features, steps, operations and / or components, but do not exclude the existence or addition of one or more other features, steps, operations or components.

[0076] All terms used herein, including technical and scientific terms, have the meanings commonly understood by those skilled in the art, unless otherwise defined. It should be noted that the terms used herein should be interpreted as having a meaning consistent with the context of this specification, and should not be interpreted in an idealized or overly rigid manner.

[0077] When using expressions such as "at least one of A, B, and C, etc.", it should generally be interpreted as the meaning of the expression generally understood by those skilled in the art. For example, "a system having at least one of A, B, and C" should include but not be limited to a system having A alone, B alone, C alone, A and B, A and C, B and C, and / or A, B, C, etc. When using expressions such as "at least one of A, B, or C, etc.", it should generally be interpreted as the meaning of the expression generally understood by those skilled in the art. For example, "a system having at least one of A, B, or C" should include but not be limited to a system having A alone, B alone, C alone, A and B, A and C, B and C, and / or A, B, C, etc.

[0078] It should also be noted that the directional terms mentioned in the embodiments, such as "upper", "lower", "front", "back", "left", "right", etc., are only reference directions of the drawings and are not intended to limit the scope of protection of the present disclosure. Throughout the drawings, the same elements are represented by the same or similar reference numerals. Conventional structures or configurations will be omitted when they may cause confusion in the understanding of the present disclosure.

[0079] In order to prevent the above-mentioned device from tipping over during operation, one method in the related art is to use a supporting device on the back panel of the electronic device. This method has the advantages of being simple and able to meet a larger angle range, but this method needs to be opened and closed twice when in use, once to open the back panel and once to open the keyboard, which is cumbersome to operate. Another method is to use a double-axle approach, that is, to set another set of shafts on the back panel. This method does not require the addition of additional components and is simple to operate, but a certain distance is required between the two sets of shafts, so a larger back panel size is required. Another method is to increase the size of the keyboard, extend it outward at the end connected to the display device, and protrude from the display device. This method is relatively simple and has high reliability, but for lightweight keyboard products, the protrusion will be large, resulting in an additional increase in the size of the keyboard.

[0080] Figure 1 The figure schematically shows a three-dimensional view of a supporting device in a state according to an embodiment of the present disclosure. Figure 2 A perspective view schematically shows a supporting device according to an embodiment of the present disclosure in another state, Figure 3 The figure schematically shows a side view of a supporting device in one state according to an embodiment of the present disclosure. Figure 4 A side view of a supporting device in another state according to an embodiment of the present disclosure is schematically shown.

[0081] As one aspect of the embodiments of the present disclosure, a supporting device is provided, such as Figures 1 to 4 As shown, the supporting device includes a first body 1, a second body 2 and a transmission mechanism 3. The first body 1 has a first mass greater than a threshold value, the second body 2 is used to carry an external electronic device 4, the transmission mechanism 3 connects a first side of the second body 2 and the first body 1, and based on the transmission mechanism 3, the second body 2 can rotate relative to the first body 1, or the first body 1 can rotate relative to the second body 2. Specifically, when the second body 2 has a first angle relative to the first body 1, the transmission mechanism 3 is in a first state, and when the second body 2 has a second angle greater than the first angle relative to the first body 1, the transmission mechanism 3 is in a second state. When the transmission mechanism 3 is in the first state, a first reference point on the first side (for example, a center point) and the center of gravity G of the first body 1 have a first distance (for example Figure 3 When the transmission mechanism 3 is in the second state, the first reference point on the first side and the center of gravity of the first body 1 have a second distance (for example Figure 3 ), the first distance D1 is greater than the second distance D2.

[0082] According to the support device of the embodiment of the present disclosure, by setting a transmission mechanism 3 between the first body 1 and the second body 2, and based on the transmission mechanism 3, the second body 2 can rotate relative to the first body 1. When the transmission mechanism 3 is in the first state, the first reference point (such as the center point) on the first side and the center of gravity of the first body 1 have a larger first distance D1, and when the transmission mechanism 3 is in the second state, the first reference point on the first side and the center of gravity of the first body 1 have a smaller second distance D2. The transmission mechanism 3 is used to make the first side of the second body 2 move forward relative to the center of gravity of the second body 2 when the transmission mechanism 3 is in the second state, so that when the entire support device is subjected to an external force (such as the operation of clicking the electronic device 4), the overturning moment is reduced, thereby increasing the stability of the support device.

[0083] For example, the first angle may be 0° or 10°, and the second angle may be any one of 90°, 120°, 150°, 160°, etc.

[0084] In order to ensure that the electronic device does not tip over during use, the lever balance condition needs to be met, namely:

[0085] F×L+G2×L2≤G1×L1(1);

[0086] Among them, F represents the external force applied to the electronic device (such as a click operation), L represents the distance from the external force applied to the electronic device to the fulcrum, G2 represents the second mass of the electronic device and the second body, L2 represents the distance from the center of gravity of the electronic device and the second body to the fulcrum, G1 represents the first mass, and L1 represents the distance from the center of gravity of the first body to the fulcrum.

[0087] The supporting device provided by the embodiment of the present disclosure enables the first body 1 to rotate relative to the second body 2 based on the transmission mechanism 3. When the transmission mechanism 3 is in the first state, the first reference point (for example, the center point) on the first side and the center of gravity of the first body 1 have a larger first distance D1. When the transmission mechanism 3 is in the second state, the first reference point on the first side and the center of gravity of the first body 1 have a smaller second distance D2, which is equivalent to reducing the distance L2 in formula (1), so that the supporting device is more stable.

[0088] In an illustrative embodiment, Figure 2As shown, the first body 1 may be provided with an input device 12, and the input device 12 may be used to perform input operations on the electronic device 4 provided on the second body 2. It is understandable that the input device 12 may be provided integrally with the first body 1 (for example, the input device 12 is integrated into the first body 1), or may be provided separately from the first body 1 (for example, a separate input device may be used and placed on the first body 1).

[0089] In such an embodiment, the input device 12 may include one or more of a keyboard, a touch display screen, and a touch pad.

[0090] Figure 5 Schematically shows a three-dimensional view of a supporting device in another state according to an embodiment of the present disclosure, Figure 6 Schematically shows Figure 5 A partial enlarged view of part A of the supporting device shown, Figure 7 Schematically shows Figure 5 A side view of the supporting device in one state is shown, Figure 8 Schematically shows Figure 5 A side view of the support device in another state is shown.

[0091] According to the embodiments of the present disclosure, Figures 5 to 8 As shown, the transmission mechanism 3 includes a rotating shaft (for example, a first rotating shaft 31 connected to the first body 1, or a reversing shaft 341 located between the first rotating shaft 31 and the second rotating shaft 33, wherein the first rotating shaft 31, the second rotating shaft 33 and the reversing shaft 341 will be described in detail later), when the transmission mechanism 3 is in a first state, the rotating shaft has a first position state, when the transmission mechanism 3 is in a second state, the rotating shaft has a second position state, in the first position state, the rotating shaft has a third distance (for example, Figure 3 In the second position, the rotation axis is at a fourth distance (eg, Figure 4 H2 in the figure), the fourth distance H2 is smaller than the third distance H1.

[0092] In such an embodiment, when the transmission mechanism 3 moves from the first state to the second state, the rotation axis moves relative to the plane (e.g., the placement surface) where the first body 1 is located toward the plane, thereby reducing the distance between the center of gravity G of the second body 2 and the rotation axis, which is equivalent to reducing L2 in formula (1), thereby helping to prevent the electronic device 4 from tipping over during use.

[0093] Fig. 9 A partial exploded view of a supporting device according to an embodiment of the present disclosure is schematically shown. Fig.10 Schematically shows Fig. 9 A partial enlarged view of part B of the supporting device is shown.

[0094] According to the embodiments of the present disclosure, Figure 6 , Fig. 9 and Fig.10 As shown, the transmission mechanism 3 includes a first rotating shaft 31 and a second rotating shaft 33, and the first axis of the first rotating shaft 31 is parallel to the second axis of the second rotating shaft 33. The second body 2 performs a first rotation relative to the transmission mechanism 3 around the first axis in a first direction (for example, it can be self-rotation), so that the second body 2 follows the transmission mechanism 3 around the second axis and performs a second rotation relative to the first body 1 in a second direction opposite to the first direction (for example, it can be revolution), so as to move from the first state to the second state, or from the second state to the first state.

[0095] In an exemplary embodiment, the second body 2 rotates clockwise around the first axis while the transmission mechanism 3 rotates counterclockwise around the second axis. Alternatively, the second body 2 rotates counterclockwise around the first axis while the transmission mechanism 3 rotates clockwise around the second axis.

[0096] In this embodiment, by setting a first rotating shaft 31 and a second rotating shaft 33 parallel to each other, and installing the second body 2 on the first rotating shaft 31, and the first body 1 on the second rotating shaft 33, when an external force drives the second body 2 to rotate around the first axis in a first direction relative to the transmission mechanism 3, the second body 2 can follow the transmission mechanism 3 to revolve around the second axis in a second direction opposite to the first direction relative to the first body 1. In this way, after the second body 2 rotates to a certain operating angle relative to the first body 1, the center of gravity of the second body 2 can move forward relative to the first side of the first body, thereby reducing the overturning moment and preventing the supporting device from tipping over.

[0097] In an illustrative embodiment, Figure 1 , Figure 2 , Figure 5 and Figure 6 As shown, the first body 1 is provided with an axle seat 11, and one end of the second rotating shaft 33 extends into the axle 11, so that the second rotating shaft 33 is stationary relative to the axle seat 11. The second body 2 is provided with a mounting seat 21 on the first side, and one end of the second rotating shaft 33 extends into the mounting seat 21, so that the second rotating shaft 33 can rotate with the second body 2 and remain stationary relative to the mounting seat 21.

[0098] Fig.11 Schematically shows Fig. 9 A partial enlarged view of part C of the supporting device is shown.

[0099] According to the embodiments of the present disclosure, Figure 6 , Fig. 9 and Fig.11As shown, the transmission mechanism 3 further includes a support assembly 32 and a reversing assembly 34. The support assembly 32 is adapted to be rotatably mounted between the first rotating shaft 31 and the second rotating shaft 33. The reversing assembly 34 is rotatably mounted on the support assembly 32, and the reversing assembly 34 is adapted to convert a first rotation of the first rotating shaft 31 in a first direction around the first axis relative to the support assembly 32 into a second rotation of the second body 2 in a second direction relative to the first body 1 around the second axis along with the support assembly 32.

[0100] In such an embodiment, the first rotating shaft 31 and the second rotating shaft 33 can rotate relative to the supporting assembly 32, and through the cooperation of the supporting assembly with the reversing assembly, the rotation of the second body 2 around the first axis in the first direction relative to the transmission mechanism 3 is converted into the revolution of the second body 2 around the second axis in the second direction relative to the first body 1.

[0101] In such an embodiment, by setting the support assembly 32 to cooperate with the reversing assembly 34, the rotation of the first body 1 in the first direction around the first axis is converted into the revolution of the second body 2 in the second direction around the second axis along with the support assembly 32, which can simplify the opening and closing action and has the advantages of simple operation and good stability.

[0102] Fig.12 A perspective view of a first rotating shaft according to an embodiment of the present disclosure is schematically shown.

[0103] According to the embodiments of the present disclosure, Figure 6 , Fig.11 and Fig.12 As shown, a first gear sleeve 311 is provided on the first rotating shaft 31, and a second gear sleeve 331 is provided on the second rotating shaft 33. The reversing assembly 34 includes a reversing shaft 341 and a gear sleeve group 342. The reversing shaft 341 is installed in parallel between the first rotating shaft 31 and the second rotating shaft 33 through the supporting assembly 32, and the gear sleeve group 342 is provided on the reversing shaft 341 and meshes with the first gear sleeve 311 and the second gear sleeve 331 to convert the first rotation into the second rotation.

[0104] In such an embodiment, the first gear sleeve 311 is stationary relative to the first rotating shaft 31 , the second gear sleeve 331 is stationary relative to the second rotating shaft 33 , and the gear sleeve set 342 is stationary relative to the reversing shaft 341 .

[0105] It is understandable that the first gear sleeve 311 can be integrally provided with the first rotating shaft 31, or can be separately provided with the first rotating shaft 31. In the case where the first gear sleeve 311 is separately provided with the first rotating shaft 31, the cross section of at least the first mounting section of the first rotating shaft 31 for mounting the first gear sleeve 311 is non-circular (for example, it can be D-shaped or rectangular), so that when the first mounting section passes through the first through hole of the first gear sleeve 311, it cooperates with the first through hole, so that the first gear sleeve 311 can rotate with the first rotating shaft 31. The cross section of the first through hole matches the cross section shape of the first mounting section.

[0106] Similarly, the second gear sleeve 331 may be integrally or separately provided with the second rotating shaft 33 , and the reversing gear sleeve may be integrally or separately provided with the reversing shaft 341 .

[0107] Fig.13 A perspective view of a first reversing gear sleeve according to an embodiment of the present disclosure is schematically shown.

[0108] According to the embodiments of the present disclosure, Figure 6 , Fig.11 and Fig.13 As shown, the gear sleeve set 342 includes a first reversing gear sleeve 3421 and a second reversing gear sleeve 3422. The first reversing gear sleeve 3421 is meshed with the first gear sleeve 311, and the second reversing gear sleeve 3422 is meshed with the second gear sleeve 331 to convert the first rotation into the second rotation.

[0109] In an illustrative embodiment, Fig.13 As shown, at least one of the first reversing gear sleeve 3421 and the second reversing gear sleeve 3422 can be separately provided with the reversing shaft 341. In the case of being separately provided with the reversing shaft 341, the cross section of the mounting section of the reversing shaft 341 for mounting the first reversing gear sleeve 3421 and the second reversing gear sleeve 3422 is non-circular, so as to cooperate with the mounting holes on the first reversing gear sleeve 3421 and the second reversing gear sleeve 3422, so that the first reversing gear sleeve 3421 and the second reversing gear sleeve 3422 rotate with the reversing shaft 341 at the same time.

[0110] According to an embodiment of the present disclosure, the number of teeth of the first reversing gear sleeve 3421 is greater than the number of teeth of the second reversing gear sleeve 3422, and / or the number of teeth of the first reversing gear sleeve 3421 is greater than the number of teeth of the first gear sleeve 311, and / or the number of teeth of the second gear sleeve 331 is greater than the number of teeth of the second reversing gear sleeve 3422.

[0111] like Figure 4 As shown, the angle of rotation of the second body 2 relative to the first body 1 is a and the angle of rotation of the transmission mechanism 3 relative to the first body 1 is b, then the angle of rotation of the second body 2 relative to the transmission mechanism 3 is:

[0112] c = a + b (2);

[0113] To ensure the matching of the rotation angle, the number of teeth z1 of the first gear sleeve 311, the number of teeth z4 of the second reversing gear sleeve 3422, the number of teeth z3 of the first reversing gear sleeve 3421, the number of teeth z4 of the second reversing gear sleeve 3422, the angle a of the second body 2 relative to the first body 1, and the angle c of the second body 2 relative to the transmission mechanism 3 should satisfy:

[0114] (3);

[0115] (4);

[0116] (5);

[0117] Wherein, m is a first transmission ratio between the first gear sleeve 311 and the first reversing gear sleeve 3421 , and n is a second transmission ratio between the second reversing gear sleeve 3422 and the second reversing gear sleeve 3422 .

[0118] It can be seen from formulas (3)-(4) that the number of teeth z3 of the first reversing gear sleeve 3421 is greater than the number of teeth z4 of the second reversing gear sleeve 3422, which can reduce the difference between the number of teeth z1 of the first gear sleeve 311 and the number of teeth z2 of the second gear sleeve 331, thereby avoiding the second gear sleeve 331 from being too large and reducing the volume and weight of the support device.

[0119] In such an embodiment, the number of teeth z3 of the first reversing gear sleeve 3421 is greater than the number of teeth z1 of the first gear sleeve 311 , which can reduce the difference in the number of teeth between the second reversing gear sleeve 3422 and the second gear sleeve 331 .

[0120] In such an embodiment, the number of teeth z2 of the second gear sleeve 331 is greater than the number of teeth z4 of the second reversing gear sleeve 3422 , which can reduce the difference in the number of teeth between the first gear sleeve 311 and the first reversing gear sleeve 3421 .

[0121] According to the embodiments of the present disclosure, Figure 6 and Fig.11 As shown, the support assembly 32 includes two brackets installed at intervals in a direction parallel to the first axis, the two brackets are respectively a first bracket 321 and a second bracket 322, and each bracket is formed with mounting holes arranged at intervals in a direction perpendicular to the first axis, and the first rotating shaft 31, the second rotating shaft 33 and the reversing shaft 341 are respectively installed on the two brackets through the mounting holes.

[0122] According to the embodiments of the present disclosure, Figure 6 and Fig.11 As shown, the transmission mechanism 3 further includes a damping assembly 35. The damping assembly 35 is mounted on at least one of the first rotating shaft 31 and the second rotating shaft 33, and is adapted to cooperate with the supporting assembly 32 to restrict the second body 2 to a target posture.

The locking member 352 is adapted to cooperate with the support assembly 32 to apply pressure to the plurality of elastic rings 351, to press the plurality of elastic rings 351 against each other, to generate sufficient friction between the elastic rings 351, thereby increasing the friction between the elastic ring 351 and at least one of the first rotating shaft 31 and the second rotating shaft 33, and to limit the posture of the second body 2.

[0125] In an exemplary embodiment, the elastic ring 351 is made of a material with a high friction coefficient, such as rubber, leather, a composite material or other special friction materials.

[0126] In an exemplary embodiment, the first shaft 31 and the second shaft 33 are formed with external threads on at least the surface for mounting the locking member 352, and the locking member 352 can be a nut threadably matched with the external threads.

[0127] Fig.14 A three-dimensional diagram of a first limiting unit according to an embodiment of the present disclosure is schematically shown.

[0128] According to the embodiments of the present disclosure, Figure 6 , Fig.11 and Fig.14 As shown, the support assembly 32 further includes a first limiting unit 324. The first limiting unit 324 is mounted on the first rotating shaft 31 and is adjacent to the first bracket 321 of the two brackets. The first limiting unit 324 is configured to be snap-fitted with the first bracket 321 when the mounting surface of the second body 2 is parallel to the upper surface of the first body 1, so as to limit the second body 2 to the target position.

[0129] In an illustrative embodiment, Fig.14As shown, a through hole 3241 is provided on the first limiting unit 324, and the shape of the through hole 3241 is non-circular. The cross-sectional shape of the second mounting section of the first rotating shaft 31 for mounting the first limiting unit 324 on the first rotating shaft matches the shape of the through hole 3241, so that the first limiting unit 324 rotates with the first rotating shaft 31. It can be understood that the second mounting section can be connected to the first mounting section.

[0130] Fig.15 Schematically shows a stereoscopic view of a first bracket according to an embodiment of the present disclosure from a first viewing angle, Fig.16 A stereoscopic view of a first bracket at a second viewing angle according to an embodiment of the present disclosure is schematically shown.

[0131] In an illustrative embodiment, Fig.15 and Fig.16 As shown, a plurality of mounting holes 323 are provided on the first bracket to respectively mount the first rotating shaft 31 , the second rotating shaft 33 and the reversing shaft 341 , and allow the first rotating shaft 31 , the second rotating shaft 33 and the reversing shaft 341 to rotate within the plurality of mounting holes 323 .

[0132] In an illustrative embodiment, Figure 6 and Fig.14 As shown, a surface of the first limiting unit 324 on one side facing the first bracket 321 extends in the first axis direction toward the direction close to the first bracket 321 to form at least one protrusion 3242 .

[0133] like Fig.15 As shown, the surface of the first bracket 321 on one side facing the first limiting unit 324 is recessed inwardly in the first axial direction in the direction away from the first bracket 321 to form at least one groove 3213 that matches the protrusion 3242. When the mounting surface of the second body 2 is parallel to the upper surface of the first body 1, the protrusion 3242 on the first limiting unit 324 matches the groove 3213 on the first bracket 321 to limit the second body 2 to the current target position. When the second body 2 is subjected to a sufficiently large external force, the groove 3213 can be disengaged from the protrusion 3242 to facilitate adjustment of the angle of the second body 2 relative to the first body 1.

[0134] It can be understood that the surface of the first limiting unit 324 on the side facing the first bracket 321 can also be recessed in the first axial direction in a direction away from the first bracket 321 to form at least one groove, and the surface of the first bracket 321 on the side facing the first limiting unit 324 can also extend outward in the first axial direction toward the direction close to the first bracket 321 to form at least one protrusion that matches the groove.

[0135] In an illustrative embodiment, there may be multiple protrusions 3242 arranged at different radial positions of the first limiting unit 324 to avoid being restricted after the first limiting unit 324 rotates relative to the first bracket 321 to an angle between two protrusions.

Fig.16 As shown, one side of the first rotating shaft 31 bracket extends toward the second limiting unit 325 along the first axial direction toward the direction close to the second limiting unit 325 to form a blocking cantilever 3211, and the second limiting unit 325 is constructed to abut against the blocking cantilever 3211 when the plane where the mounting surface of the second body 2 is located is parallel to the upper surface of the first body 1, so as to prevent the second body 2 from further rotating toward the upper surface of the first body 1.

[0138] In an illustrative embodiment, Fig.17 As shown, the second limiting unit 325 extends outward in the radial direction to form a blocking protrusion 3251. When the plane where the mounting surface of the second body 2 is located is parallel to the upper surface of the first body 1, the blocking protrusion 3251 abuts against the blocking cantilever 3211, limiting the second body 2 from further rotating toward the first body 1.

[0139] In an illustrative embodiment, the second limiting unit 325 may be configured to be cylindrical.

[0140] In an illustrative embodiment, at least a portion of the first rotating shaft 31 in the axial direction is the third mounting section, the cross section of the third mounting section is non-circular (for example, it can be D-shaped or rectangular), and the through hole located on the axis of the second limiting unit 325 and the through hole 3241 on the first limiting unit 324 both match the cross-sectional shape of the third mounting section, so that the first limiting unit 324 and the second limiting unit 325 rotate with the first rotating shaft 31. It can be understood that the third mounting section can also extend to the second extension section, or even to the first mounting section.

[0142] In an illustrative embodiment, Fig.18As shown, a plurality of mounting holes 323 are provided on the second bracket 322 of the two brackets. The first rotating shaft 31, the second rotating shaft 33 and the reversing shaft 341 are respectively installed on the first bracket 321 through the mounting holes 323, and the first rotating shaft 31, the second rotating shaft 33 and the reversing shaft 341 are allowed to rotate in the plurality of mounting holes 323.

The end cover 361 passes through the first rotating shaft 31 and the second rotating shaft 33 and is installed on one end of the first rotating shaft 31 and the second rotating shaft 33 close to the shaft seat 11, and the body 362 is configured to be a barrel with an opening at one end, and the opening faces the end cover 361, so as to cooperate with the end cover 361 to form a receiving space.

[0146] In an illustrative embodiment, a bracket (for example, the first bracket 321 or the second bracket 322) near the end of the main body 362 extends in a direction parallel to the axial direction of the reversing shaft 341 toward the end of the housing to form an extension. A through hole is provided at the end of the main body 362, and a fixing member (for example, a screw) passes through the through hole and is threadedly engaged with the extension to mount the main body 362 on the bracket.

[0147] In an exemplary embodiment, two opposite side walls of the main body 362 extend toward each other to form a locking portion. Fig.10 As shown, one end of the end cover 361 close to the main body forms a fitting portion engaged with the engaging portion, so as to preliminarily fix the main body 362 when the main body 362 is installed on the end cover 361 to prevent the main body 362 from falling off.

[0148] In an exemplary embodiment, the bracket close to the end of the main body 362 is the first bracket. Fig.15 and Fig.16 As shown, the first bracket extends in a direction parallel to the axial direction of the reversing shaft 341 toward the end of the housing to form an extension portion 3212. The fixing member 363 passes through the through hole of the body portion 362 to mount the body portion 362 on the first bracket 321.
