It should be noted that for those of ordinary skill in the art in this technical field, without departing from the principle of the present application, several improvements and refinements can still be made, and these improvements and refinements are also regarded as the protection scope of the present application.

[0059] In view of this, to solve the above problems, the present application provides a motor and a hair trimmer. Please refer to Figures 1 - 7 , Figure 1 which is a perspective structural view of the motor in an embodiment of the present application.

[0060] The motor 1 provided by this embodiment includes a frame 10, a driving assembly 20, a motion module 30a, and a suspension assembly 40. At least part of the driving assembly 20, at least part of the motion module 30a, and at least part of the suspension assembly 40 are disposed within the frame 10. The motion module 30a is connected to one side of the driving assembly 20. The driving assembly 20 and the motion module 30a cooperate with each other to be reciprocally movable along a direction perpendicular to the arrangement direction of the driving assembly 20 and the motion module 30a. One end of the suspension assembly 40 is connected to the driving assembly 20, and the other end is connected to the frame 10. The suspension assembly 40 includes a suspension member 41. The suspension member 41 is provided with a through hole 410 along its thickness direction. Along the arrangement direction of the driving assembly 20 and the motion module 30a, the suspension member 41 includes a first side 412 and a second side 413 that are oppositely disposed. The through hole 410 extends along the direction from the first side 412 to the second side 413, and there is a gap between the through hole 410 and both the first side 412 and the second side 413.

[0061] The motor 1 provided by this embodiment is mainly applied to various devices that require reciprocating movement, such as small appliances like personal cleaning devices and household electronic devices. In this embodiment, only the hair trimmer 5 in the personal cleaning device is used for illustrative purposes.

[0062] The frame 10 mainly provides a mounting basis for other components of the motor 1. For example, at least part of the driving assembly 20, at least part of the motion module 30a, and at least part of the suspension assembly 40 are disposed within the frame 10. It should be noted that the driving assembly 20, the motion module 30a, and the suspension assembly 40 can all be only partially disposed within the frame 10, and the remaining parts are disposed outside the frame 10, or the driving assembly 20, the motion module 30a, and the suspension assembly 40 are all entirely disposed inside the frame 10. And subsequently, the entire motor 1 can also be mounted on the housing 2 of the hair trimmer 5 through the frame 10.

[0063] The driving assembly 20 mainly plays a driving role. After the driving assembly 20 is powered on and operates, an electromagnetic field effect can be generated. The motion module 30a can be connected to the driving assembly 20 and is disposed on one side of the driving assembly 20. For example, the motion module 30a and the driving assembly 20 are arranged vertically. The driving assembly 20 and the motion module 30a cooperate with each other to be reciprocally movable along a direction perpendicular to the arrangement direction of the driving assembly 20 and the motion module 30a, that is, both the driving assembly 20 and the motion module 30a can reciprocally move horizontally left and right. Specifically, the motion module 30a can reciprocally move left and right under the electromagnetic effect of the driving assembly 20, and the motion module 30a can also make the driving assembly 20 reciprocally move left and right.

[0064] Optionally, the moving directions of the motion module 30a and the driving assembly 20 can be the same or opposite. When the moving directions of the motion module 30a and the driving assembly 20 are opposite, the vibrations can be mutually offset, reducing the vibration of the motor 1.

[0065] Optionally, a driving component 20 and a motion module 30a form a motion module, and the motor 1 includes at least one motion module. In this embodiment, only two motion modules are schematically illustrated, and the two motion modules are arranged along a direction perpendicular to the moving direction of the driving component 20 and the motion module 30a.

[0066] Further optionally, the moving directions of the two motion modules can be the same or opposite. When the moving directions of the two motion modules are opposite, the vibrations can be further cancelled out with each other, further reducing the vibration of the motor 1.

[0067] As can be seen from the above, the entire motion module 30a is connected to the driving component 20. During the movement, whether it is the reciprocating movement of the driving component 20 or the reciprocating movement of the motion module 30a, the vibration caused by the final reciprocating movement will be transmitted to the driving component 20. Therefore, in this embodiment, a suspension component 40 can be added, and the driving component 20 can be connected to the frame 10 through the suspension component 40. Specifically, one end of the suspension component 40 is connected to the driving component 20, and the other end of the suspension component 40 is connected to the frame 10. Therefore, the vibration generated by the driving component 20 can be transmitted to the frame 10 through the suspension component 40, and the driving component 20 is not directly connected to the frame 10. Since the suspension component 40 itself has certain elasticity and flexibility and is not completely rigid, the suspension component 40 can be used to absorb part of the vibration generated during the reciprocating movement of the driving component 20 and the motion module 30a, playing a role in vibration reduction.

[0068] Optionally, since the user usually holds the whole machine device in the middle or the lower middle part of the whole machine, the other end of the suspension component 40 can be connected to the top of the frame 10, and there is a distance between the driving component 20 and the bottom of the frame 10, so as to play a role of suspension. In this way, the vibration of the driving component 20 can be transmitted upward and will not be transmitted downward, reducing the vibration feeling when the user holds it and improving the comfort of the user.

[0069] It should be noted that the suspension function mentioned in this embodiment means that when the housing 2 in the hair trimmer 5 is placed on a table, the ground, etc. and the cutter head 4 is arranged upward, at this time, for the direction of gravity, the suspension component 40 can play a suspension role, so it is named the suspension component 40. When the motor 1 or even the hair trimmer 5 adopts other placement methods, the suspension component 40 can be called a connection component.

[0070] Optionally, each driving component 20 is cooperatively connected with two suspension components 40. Specifically, along the reciprocating movement direction of the driving component 20, the two suspension components 40 are connected to opposite ends of the driving component 20 to improve the symmetry and stability of the structure. Of course, in other embodiments, each driving component 20 can also be cooperatively connected with one suspension component 40, three suspension components 40, or even more suspension components 40.

[0071] The suspension component 40 mainly includes a suspension member 41. As for the remaining components of the suspension component 40, they will be introduced in detail later in this application. The suspension function of the suspension member 41 and the suspension component 40 is only for a specific placement method, and the same understanding can be made with reference to the above content, which will not be elaborated in this embodiment. The suspension member 41 is a structural member with a relatively thin thickness and in a sheet shape. One end of the suspension member 41 can be connected to the driving component 20, and the other end of the suspension member 41 is connected to the frame 10. Therefore, the suspension member 41 itself has a certain elasticity and flexibility, and can perform a certain amount of elastic bending and deformation, so as to absorb part of the vibration brought by the reciprocating movement. The number of suspension members 41 can be one or multiple. In this embodiment, only three suspension members 41 are used for illustrative purposes.

[0072] Since the suspension member 41 needs to be connected to the driving component 20 and the frame 10, no matter what connection method is adopted, for example, when riveting through rivets, through holes 411 will be opened on the suspension member 41, and the rivets are connected and fixed through the through holes 411. Due to the manufacturing tolerance of the suspension member 41 itself and the assembly tolerance during connection, both will cause certain internal stress in the suspension member 41 after connection, that is, stress concentration will occur in the suspension member 41, resulting in local warping, arching, etc. of the suspension member 41, or the suspension member 41 will be more prone to plastic bending when the whole machine drops, thereby reducing the vibration damping effect and even affecting the reciprocating movement of the driving component 20 and the motion module 30a. Therefore, in this embodiment, by opening through holes 410 in the thickness direction of the suspension member 41, the internal stress of the suspension member 41 can be reduced, and the stress concentration generated by the suspension member 41 during the assembly process can be reduced, thereby preventing local deformation of the suspension member 41. Among them, as Figures 6 - 7 shown, the thickness direction of the suspension member 41 can be understood as the reciprocating movement direction of the driving component 20 and the motion module 30a. In addition, the arrangement direction along the driving component 20 and the motion module 30a can also be understood as the length direction of the suspension member 41. Similarly, the direction perpendicular to the arrangement direction of the driving component 20 and the motion module 30a can also be understood as the width direction of the suspension member 41.

[0073] In the length direction of the suspension member 41, the suspension member 41 includes a first side 412 and a second side 413 which are oppositely arranged, that is, the upper side or the lower side. As for which of the first side 412 and the second side 413 is the upper side and which is the lower side, this embodiment does not limit it here. The direction from the first side 412 to the second side 413 is the same as the arrangement direction of the driving assembly 20 and the motion module 30a, which is also understood as the length direction of the suspension member 41. In this embodiment, the through hole 410 can be arranged to extend vertically up and down along the length direction of the suspension member 41. Compared with the through hole 410 that extends horizontally along the width direction, the through hole 410 that extends vertically up and down can improve the strength of the suspension member 41 on the basis of relieving stress concentration, avoid the bending deformation of the suspension member 41 caused by the whole machine falling, and improve the anti-falling performance.

[0074] In addition, when the through hole 410 extends vertically up and down, the through hole 410 does not penetrate the upper and lower sides, that is, the first side 412 and the second side 413, but has a certain distance from both the first side 412 and the second side 413. In other words, the through hole 410 only penetrates the opposite two side surfaces in the thickness direction of the suspension member 41, and does not penetrate the opposite two side surfaces in the length direction of the suspension member 41. Compared with the through hole 410 that not only penetrates the opposite two side surfaces in the thickness direction of the suspension member 41 but also penetrates one side surface in the length direction of the suspension member 41, at this time, the shape of the suspension member 41 is U-shaped. The present application can further improve the strength of the suspension member 41, avoid bending deformation during falling, and further improve the anti-falling performance.

[0075] In summary, in this embodiment, adding the suspension assembly 40 can reduce vibration. Opening the through hole 410 with a specific structure on the suspension member 41 in the suspension assembly 40 can reduce stress concentration, improve strength, avoid falling deformation, and improve the anti-falling performance.

[0076] In this embodiment, the suspension member 41 satisfies at least one of the following conditions: The suspension member 41 has a length direction along the first side 412 to the second side 413. Along the length direction, the vertical distance from the through hole 410 to the edge of the suspension member 41 is 15%-25% of the length of the suspension member 41. The suspension member 41 has a width direction perpendicular to the first side 412 to the second side 413. Along the width direction, the vertical distance from the through hole 410 to the edge of the suspension member 41 is 20%-40% of the width of the suspension member 41.

[0077] As can be seen from the above content, there is a distance between the through hole 410 in the suspension member 41 and both the first side 412 and the second side 413. In this embodiment, the vertical distance (such as Figure 7 shown as L1) from the through hole 410 to the edge of the suspension member 41 (that is, the first side 412 or the second side 413) can be the length of the suspension member 41 (such as Figure 715%-25% of that shown as L in the figure. If the proportion of the vertical distance from the through hole 410 to the edge of the suspension member 41 in the length of the suspension member 41 is too small, for example, less than 15%, the through hole 410 is too close to the edge in the length direction of the suspension member 41, and the strength at this edge is too small, making it prone to plastic bending deformation and having poor anti-drop performance, unable to meet the anti-drop requirements. If the proportion of the vertical distance from the through hole 410 to the edge of the suspension member 41 in the length of the suspension member 41 is too large, for example, greater than 25%, the through hole 410 will be too far from the edge, resulting in insufficient length or quantity of the through hole 410, reducing the flexibility of the suspension member 41, making the suspension member 41 unable to fully release internal stress and reducing the vibration damping effect.

[0078] In summary, in this embodiment, by making the vertical distance from the through hole 410 to the edge of the suspension member 41 be 15%-25% of the length of the suspension member 41, the suspension member 41 can have excellent strength and anti-drop performance, and can fully absorb internal stress, avoid stress concentration, and improve the vibration damping effect.

[0079] Optionally, the vertical distance from the through hole 410 to the edge of the suspension member 41 is 15%, 17%, 19%, 21%, 23%, 25%, etc. of the length of the suspension member 41.

[0080] Optionally, in the length direction, the vertical distance from the through hole 410 to the edge of the suspension member 41 is 4 mm - 5 mm. Further optionally, the vertical distance from the through hole 410 to the edge of the suspension member 41 can be 4 mm, 4.2 mm, 4.4 mm, 4.6 mm, 4.8 mm, 5 mm, etc.

[0081] Optionally, the length of the suspension member 41 is 15 mm - 30 mm. Further optionally, the length of the suspension member 41 can be 15 mm, 20 mm, 25 mm, 30 mm, etc.

[0082] Similarly, the direction perpendicular to the first side 412 to the second side 413 is the width direction of the suspension member 41. In the width direction, the vertical distance from the through hole 410 to the edge of the suspension member 41 (as Figure 7 shown as D1 in the figure) is the width of the suspension member 41 (as Figure 720% - 40% of that shown in Figure D. If the ratio of the vertical distance from the through - hole 410 to the edge of the suspension member 41 to the width of the suspension member 41 is too small, for example, less than 20%, the through - hole 410 will be too close to the edge in the width direction of the suspension member 41. The strength at this edge is too small, and it is prone to plastic bending deformation, resulting in poor anti - drop performance and unable to meet the anti - drop requirements. Moreover, being too close to the edge in the width direction has a greater impact on strength reduction than being too close to the edge in the length direction. If the ratio of the vertical distance from the through - hole 410 to the edge of the suspension member 41 to the width of the suspension member 41 is too large, for example, greater than 40%, the through - hole 410 will be too far from the edge, resulting in insufficient width or quantity of the through - hole 410, or too small a spacing between two adjacent sub - through - holes 414. This will not only reduce the strength but also reduce the flexibility of the suspension member 41, making the suspension member 41 unable to fully release internal stress and reducing the vibration - damping effect.

[0083] In summary, in this embodiment, by making the vertical distance from the through - hole 410 to the edge of the suspension member 41 be 20% - 40% of the width of the suspension member 41, the suspension member 41 can have excellent strength and anti - drop performance, and can fully absorb internal stress, avoid stress concentration, and improve the vibration - damping effect.

[0084] Optionally, the vertical distance from the through - hole 410 to the edge of the suspension member 41 is 20%, 25%, 30%, 35%, 40%, etc. of the width of the suspension member 41.

[0085] Optionally, in the width direction, the vertical distance from the through - hole 410 to the edge of the suspension member 41 is 2 mm - 3 mm. Further optionally, the vertical distance from the through - hole 410 to the edge of the suspension member 41 can be 2 mm, 2.2 mm, 2.4 mm, 2.6 mm, 2.8 mm, 3 mm, etc.

[0086] Optionally, the width of the suspension member 41 is 6 mm - 10 mm. Further optionally, the width of the suspension member 41 can be 6 mm, 6.5 mm, 7 mm, 7.5 mm, 8 mm, 8.5 mm, 9 mm, 9.5 mm, 10 mm, etc.

[0087] It should be noted that in this embodiment, only the proportional relationship in the length direction can be satisfied, or only the proportional relationship in the width direction can be satisfied, or both the proportional relationship in the length direction and the proportional relationship in the width direction can be satisfied.

[0088] In this embodiment, the suspension member 41 has a length direction from the first side 412 to the second side 413, and the included angle between the extending direction of the through hole 410 and the length direction is 0° - 10°. When the included angle between the extending direction of the through hole 410 and the length direction is 0°, the through hole 410 extends vertically at this time. When the included angle between the extending direction of the through hole 410 and the length direction is greater than 0°, the through hole 410 can be slightly inclined on the basis of vertical extension. If the inclination angle is too large, for example, greater than 10°, the through hole 410 will extend too much in the width direction, thereby reducing the strength and not meeting the drop test requirements.

[0089] In summary, in this embodiment, by making the included angle between the extending direction of the through hole 410 and the length direction be 0° - 10°, the suspension member 41 can have excellent strength on the basis of solving stress concentration. In this embodiment, only the case where the included angle between the extending direction of the through hole 410 and the length direction is 0° is used for illustrative purposes.

[0090] Optionally, the included angle between the extending direction of the through hole 410 and the length direction can be 0°, 2°, 4°, 6°, 8°, 10°, etc.

[0091] In this embodiment, the total area of the through hole 410 is 2% - 5% of the area of the suspension member 41. In this embodiment, the through hole 410 can be composed of one sub-through hole 414 or multiple sub-through holes 414. The total area of the through hole 410 can be understood as the sum of the areas of all sub-through holes 414. In this embodiment, the total area of the through hole 410 is only illustrated by the sum of the areas of four sub-through holes 414. In this embodiment, the total area of the through hole 410 can be made 2% - 5% of the area of the suspension member 41. If the proportion of the total area of the through hole 410 in the area of the suspension member 41 is too small, for example, less than 2%, it will not only lead to an insufficient number of sub-through holes 414 and be unable to solve the stress concentration problem, but also make the area of each sub-through hole 414 too small, increasing the manufacturing difficulty. If the proportion of the total area of the through hole 410 in the area of the suspension member 41 is too large, for example, greater than 5%, the total area of the through hole 410 will be too large, reducing the overall strength of the suspension member 41.

[0092] In summary, in this embodiment, by making the total area of the through hole 410 be 2% - 5% of the area of the suspension member 41, on the basis of solving the stress concentration problem of the suspension member 41, the suspension member 41 can also have excellent strength.

[0093] Optionally, the total area of the through hole 410 is 2%, 3%, 4%, 5%, etc. of the area of the suspension member 41.

[0094] Optionally, the total area of the through hole 410 is 5mm 2 - 8mm 2Optionally, the total area of ​​the through hole 410 may be 5 mm 2 、6mm 2 , 7mm 2 , 8mm 2 wait.

[0095] Optionally, the area of ​​the suspension member 41 is 150 mm 2 -200mm 2 Optionally, the area of ​​the suspension member 41 may be 150 mm 2 、160mm 2 、170mm 2 、180mm 2 、190mm 2 , 200mm 2 wait.

[0096] In this embodiment, the suspension member 41 satisfies at least one of the following conditions: the suspension member 41 has a length direction along the first side 412 to the second side 413, and along the length direction, the total length of the through hole 410 is 10%-90% of the length of the suspension member 41. The suspension member 41 has a width direction along the first side 412 to the second side 413 perpendicular to the first side 412, and along the width direction, the total width of the through hole 410 is 3%-40% of the width of the suspension member 41.

[0097] On the basis that the total area of ​​the through hole 410 is 2%-5% of the area of ​​the suspension member 41, the present embodiment further defines the relationship between the total length and total width of the through hole 410 and the length and width of the suspension member 41. Specifically, in the length direction, the total length of the through hole 410 can be equal to the length of the suspension member 41 (e.g. Figure 7 The total length of the through hole 410 can be understood as the sum of the lengths of the sub-through holes 414 in the same column. In this embodiment, the total length of the through hole 410 is only the sum of the lengths of the two sub-through holes 414 (as shown in FIG. Figure 7 If the total length of the through hole 410 accounts for too small a proportion of the length of the suspension 41, for example, less than 10%, the vertical extension of the through hole 410 will be too small, and the stress concentration problem cannot be solved. In addition, the flexibility of the suspension 41 will be reduced, and the vibration reduction effect will be weakened. If the total length of the through hole 410 accounts for too large a proportion of the length of the suspension 41, for example, greater than 90%, the length of the through hole 410 will be too long, and the through hole 410 will be opened in most of the length direction of the suspension 41, which will reduce the strength of the suspension 41.

[0098] In summary, in this embodiment, by making the total length of the through hole 410 10%-90% of the length of the suspension member 41 , the suspension member 41 can solve the stress concentration problem and also have excellent vibration reduction effect and structural strength.

[0099] Optionally, the total length of the through-hole 410 is 10%, 20%, 30%, 40%, 50%, 60%, 70%, 80%, 90%, etc. of the length of the suspension member 41.

[0100] Optionally, the total length of the through-hole 410 is 3 mm - 18 mm. Further optionally, the total length of the through-hole 410 can be 3 mm, 6 mm, 9 mm, 12 mm, 15 mm, 18 mm, etc.

[0101] Optionally, the length of the suspension member 41 is 15 mm - 30 mm. Further optionally, the length of the suspension member 41 can be 15 mm, 20 mm, 25 mm, 30 mm, etc.

[0102] Similarly, in the width direction, the total width of the through-hole 410 can be made 3% - 40% of the width of the suspension member 41 (as shown by D in Figure 7 ). The total width of the through-hole 410 can be understood as the sum of the widths of the sub-through-holes 414 in the same row. In this embodiment, the total width of the through-hole 410 is only schematically illustrated by the sum of the widths of two sub-through-holes 414 (as shown by D2 in Figure 7 ). If the proportion of the total width of the through-hole 410 in the width of the suspension member 41 is too small, for example less than 3%, the size of the through-hole 410 will be too small, increasing the manufacturing difficulty. If the proportion of the total width of the through-hole 410 in the width of the suspension member 41 is too large, for example greater than 40%, the distance that the through-hole 410 extends in the width direction will be too long, further reducing the strength of the suspension member 41. And from actual inspection, it can be seen that the through-hole 410 extends the same distance in the length direction and the width direction, and the reduction of strength in the width direction is more obvious.

[0103] In summary, in this embodiment, by making the total width of the through-hole 410 be 3% - 40% of the width of the suspension member 41, not only can the manufacturing difficulty of the through-hole 410 be reduced, but also the suspension member 41 can have excellent strength.

[0104] Optionally, the total width of the through-hole 410 is 3%, 5%, 10%, 15%, 20%, 25%, 30%, 35%, 40%, etc. of the width of the suspension member 41.

[0105] Optionally, the total width of the through-hole 410 is 0.3 mm - 3 mm. Further optionally, the total width of the through-hole 410 can be 0.3 mm, 0.5 mm, 1 mm, 1.5 mm, 2 mm, 2.5 mm, 3 mm, etc.

[0106] Optionally, the width of the suspension member 41 is 6 mm - 10 mm. Further optionally, the width of the suspension member 41 can be 6 mm, 6.5 mm, 7 mm, 7.5 mm, 8 mm, 8.5 mm, 9 mm, 9.5 mm, 10 mm, etc.

[0107] It should be noted that in this embodiment, only the proportional relationship in the length direction may be satisfied, or only the proportional relationship in the width direction may be satisfied, or both the proportional relationship in the length direction and the proportional relationship in the width direction may be satisfied.

[0108] In this embodiment, the through hole 410 includes at least one sub-through hole 414 arranged in an array. The hanging member 41 has a length direction from the first side 412 to the second side 413, and a width direction perpendicular to the length direction from the first side 412 to the second side 413. In the length direction, the number of rows of at least one sub-through hole 414 is 1 row - 3 rows. In the width direction, the number of columns of at least one sub-through hole 414 is 1 column - 3 columns.

[0109] The through hole 410 may be composed of at least one sub-through hole 414. In other words, the through hole 410 is a set of at least one sub-through hole 414. When the number of sub-through holes 414 is multiple, the multiple sub-through holes 414 are not arranged randomly, but are arranged in an array. Specifically, in the length direction, the number of rows of at least one sub-through hole 414 is 1 row - 3 rows. In the width direction, the number of columns of at least one sub-through hole 414 is 1 column - 3 columns. Thus, at least one sub-through hole 414 can be arranged arbitrarily from 1 row * 1 column to 3 rows * 3 columns. For example, the multiple sub-through holes 414 can also be 2 rows * 3 columns, 3 rows * 1 column, etc. This embodiment only uses 2 rows * 2 columns for illustrative purposes.

[0110] In summary, by arranging at least one sub-through hole 414 in an array according to the above arrangement method, the uniformity of the overall strength of the hanging member 41 can be improved, and the internal stress can be absorbed at each part of the hanging member 41, solving the problem of stress concentration.

[0111] In this embodiment, the through hole 410 satisfies at least one of the following conditions: the distance between two adjacent rows of sub-through holes 414 is 15% - 25% of the length of the hanging member 41. The distance between two adjacent columns of sub-through holes 414 is 20% - 40% of the width of the hanging member 41.

[0112] Among multiple sub-through holes 414 in the same column, the distance between two adjacent rows of sub-through holes 414 (such as Figure 7As shown in L3 in the figure, it is 15%-25% of the length of the suspension member 41. For example, the distance between the sub-through holes 414 in the first row and the sub-through holes 414 in the second row is 15%-25% of the length of the suspension member 41, or the distance between the sub-through holes 414 in the second row and the sub-through holes 414 in the third row is 15%-25% of the length of the suspension member 41. If the ratio of the distance between two adjacent sub-through holes 414 in a row to the length of the suspension member 41 is too small, such as less than 15%, the distance between two adjacent sub-through holes 414 in a row will be too small and they will be closely arranged, which will not only reduce the strength of the suspension member 41, but even cause the suspension member 41 between two adjacent sub-through holes 414 to break. If the ratio of the distance between two adjacent sub-through holes 414 in a row to the length of the suspension member 41 is too large, such as greater than 25%, the distance between two adjacent sub-through holes 414 in a row will be large, which will excessively reduce the length of each sub-through hole 414, making the size of the through hole 410 extending in the vertical direction too small to solve the problem of stress concentration, and the flexibility of the suspension member 41 will also be reduced, and the vibration damping effect will be weakened.

[0113] In summary, in this embodiment, by making the distance between two adjacent sub-through holes 414 in a row be 15%-25% of the length of the suspension member 41, the suspension member 41 can not only solve the stress concentration problem, but also have excellent vibration damping effect and structural strength.

[0114] Optionally, the distance between two adjacent sub-through holes 414 in a row is 15%, 17%, 19%, 21%, 23%, 25%, etc. of the length of the suspension member 41.

[0115] Optionally, the distance between two adjacent sub-through holes 414 in a row is 4 mm - 5 mm. Further optionally, the distance between two adjacent sub-through holes 414 in a row can be 4 mm, 4.2 mm, 4.4 mm, 4.6 mm, 4.8 mm, 5 mm, etc.

[0116] Optionally, the length of the suspension member 41 is 15 mm - 30 mm. Further optionally, the length of the suspension member 41 can be 15 mm, 20 mm, 25 mm, 30 mm, etc.

[0117] Similarly, among the multiple sub-through holes 414 in the same row, the distance between two adjacent sub-through holes 414 in a column (such as Figure 7As shown in D3, it is 20%-40% of the width of the suspension member 41. If the ratio of the distance between two sub-through holes 414 in adjacent columns to the width of the suspension member 41 is too small, for example, less than 20%, the distance between two sub-through holes 414 in adjacent columns will be too small and they will be arranged closely, which will not only reduce the strength of the suspension member 41, but even cause the suspension member 41 between two sub-through holes 414 in adjacent columns to break. If the ratio of the distance between two sub-through holes 414 in adjacent columns to the width of the suspension member 41 is too large, for example, greater than 40%, the distance between two sub-through holes 414 in adjacent columns will be large, which will not only affect the number of columns in the array arrangement, but also make the distance between the sub-through hole 414 and the edge too close, and also reduce the strength of the suspension member 41.

[0118] In summary, in this embodiment, by making the distance between two sub-through holes 414 in adjacent columns be 20%-40% of the width of the suspension member 41, the suspension member 41 can have excellent strength.

[0119] Optionally, the distance between two sub-through holes 414 in adjacent columns is 20%, 25%, 30%, 35%, 40%, etc. of the width of the suspension member 41.

[0120] Optionally, the distance between two sub-through holes 414 in adjacent columns is 2 mm - 3 mm. Further optionally, the distance between two sub-through holes 414 in adjacent columns can be 2 mm, 2.2 mm, 2.4 mm, 2.6 mm, 2.8 mm, 3 mm, etc.

[0121] Optionally, the width of the suspension member 41 is 6 mm - 10 mm. Further optionally, the width of the suspension member 41 can be 6 mm, 6.5 mm, 7 mm, 7.5 mm, 8 mm, 8.5 mm, 9 mm, 9.5 mm, 10 mm, etc.

[0122] It should be noted that in this embodiment, only the proportional relationship in the length direction can be satisfied, or only the proportional relationship in the width direction can be satisfied, or both the proportional relationship in the length direction and the proportional relationship in the width direction can be satisfied.

[0123] In this embodiment, the through hole 410 satisfies at least one of the following conditions: two sub-through holes 414 in adjacent rows are arranged directly opposite to each other. Two sub-through holes 414 in adjacent columns are arranged directly opposite to each other.

[0124] In this embodiment, two sub-through holes 414 in adjacent rows can be arranged directly opposite to each other, or two sub-through holes 414 in adjacent columns can be arranged directly opposite to each other, or both two sub-through holes 414 in adjacent rows and two sub-through holes 414 in adjacent columns can be arranged directly opposite to each other. Compared with the staggered arrangement, the direct opposite arrangement can improve the stability and symmetry of the suspension member 41 during linear motion.

[0125] The above content details various limiting conditions of the sub-through holes 414. Next, the relationships between various limiting conditions will be continued to be introduced. In this embodiment, the through hole 410 satisfies at least one of the following conditions: among the sub-through holes 414 in the same column, the vertical distance from the edge sub-through hole 414 to the edge of the suspension member 41, the length of each sub-through hole 414, and the spacing between two adjacent rows of sub-through holes 414 are equal. Among the sub-through holes 414 in the same row, the vertical distance from the edge sub-through hole 414 to the edge of the suspension member 41, and the spacing between two adjacent columns of sub-through holes 414 are equal.

[0126] There are three limiting conditions in the same column: the vertical distance from the edge sub-through hole 414 to the edge of the suspension member 41, the length of each sub-through hole 414, and the spacing between two adjacent rows of sub-through holes 414. In this embodiment, the vertical distance from the edge sub-through hole 414 to the edge of the suspension member 41, the length of each sub-through hole 414, and the spacing between two adjacent rows of sub-through holes 414 can be made equal, that is, L1 = L2 = L3. Thereby, the uniformity of the strength of the suspension member 41 can be improved. It is avoided that due to the too large size of a certain limiting condition, the strength attenuation at a certain position is serious, and plastic bending deformation will occur here subsequently.

[0127] Similarly, there are also three limiting conditions in the same row, the vertical distance from the edge sub-through hole 414 to the edge of the suspension member 41, the spacing between two adjacent columns of sub-through holes 414, and the width of each sub-through hole 414. In this embodiment, the vertical distance from the edge sub-through hole 414 to the edge of the suspension member 41, and the spacing between two adjacent columns of sub-through holes 414 can be made equal, that is, D1 = D3. Thereby, the uniformity of the strength of the suspension member 41 can also be improved. It is avoided that due to the too large size of a certain limiting condition, the strength attenuation at a certain position is serious, and plastic bending deformation will occur here subsequently.

[0128] It should be noted that this embodiment can satisfy only the limiting conditions in the sub-through holes 414 in the same column, or only the limiting conditions in the sub-through holes 414 in the same row, or can satisfy both the limiting conditions in the sub-through holes 414 in the same column and the limiting conditions in the sub-through holes 414 in the same row.

[0129] In this embodiment, the length of each sub-through hole 414 is 3 mm - 6 mm, and the width of each sub-through hole 414 is 0.3 mm - 1 mm.

[0130] For each sub-through hole 414, the length of each sub-through hole 414 (such as Figure 7As shown by L2 in the figure, it is 3 mm - 6 mm. If the length of each sub-through hole 414 is too small, for example, less than 3 mm, the size of each sub-through hole 414 extending in the vertical direction will be too small to solve the stress concentration problem, and the flexibility of the suspension member 41 will also be reduced, weakening the damping effect. If the length of each sub-through hole 414 is too large, for example, greater than 6 mm, the length of each through hole 410 will be too long, reducing the strength of the suspension member 41. In summary, in this embodiment, by making the length of each sub-through hole 414 be 3 mm - 6 mm, the suspension member 41 can not only solve the stress concentration problem but also have excellent damping effect and structural strength.

[0131] Moreover, the width of each sub-through hole 414 (as Figure 7 shown by D2 in the figure) is 0.3 mm - 1 mm. If the width of each sub-through hole 414 is too small, for example, less than 0.3 mm, the size of the through hole 410 will be too small, increasing the manufacturing difficulty. If the width of each sub-through hole 414 is too large, for example, greater than 1 mm, the distance that the through hole 410 extends in the width direction will be too long, further reducing the strength of the suspension member 41. And from actual inspection, it can be seen that the through hole 410 extends the same distance in the length direction and the width direction, and the reduction of strength in the width direction is more obvious. In summary, in this embodiment, by making the width of each sub-through hole 414 be 0.3 mm - 1 mm, not only can the manufacturing difficulty of the through hole 410 be reduced, but also the suspension member 41 can have excellent strength.

[0132] Optionally, the length of each sub-through hole 414 can be 3 mm, 4 mm, 5 mm, or 6 mm.

[0133] Optionally, the width of each sub-through hole 414 can be 0.3 mm, 0.4 mm, 0.5 mm, 0.6 mm, 0.7 mm, 0.8 mm, 0.9 mm, or 1 mm.

[0134] In this embodiment, each sub-through hole 414 is prepared by a stamping process, and each sub-through hole 414 is a runway-shaped hole. The runway-shaped hole means that the overall shape of the through hole 410 is similar to a rectangle, but the two sides in the length direction are not straight lines but arcs. Since each sub-through hole 414 in this embodiment is prepared by a stamping process, designing the sub-through hole 414 as a runway-shaped hole can ensure the stamping stability and quality and avoid poor stamping caused by right-angled holes.

[0135] Optionally, for the R angle of the arc segment in the runway-shaped hole, the R angle can be 0.065 mm - 0.2 mm.

[0136] In this embodiment, the through-hole 410 includes a plurality of sub-through-holes 414 arranged in an array. The number of rows of the plurality of sub-through-holes 414 is 2 rows, and the number of columns of the plurality of sub-through-holes 414 is 2 columns. The suspension member 41 has a length direction along the first side 412 to the second side 413. Along the length direction, the vertical distance from the sub-through-hole 414 to the edge of the suspension member 41, the length of the sub-through-hole 414, and the distance between two adjacent sub-through-holes 414 in adjacent rows are equal. The suspension member 41 has a width direction perpendicular to the first side 412 to the second side 413. Along the width direction, the vertical distance from the sub-through-hole 414 to the edge of the suspension member 41, and the distance between two adjacent sub-through-holes 414 in adjacent columns are equal. For example, along the length direction, the length of the suspension member 41 is 20.9 mm, and the vertical distance from the sub-through-hole 414 to the edge of the suspension member 41, the length of the sub-through-hole 414, and the distance between two adjacent sub-through-holes 414 in adjacent rows are all 4 mm. Along the width direction, the width of the suspension member 41 is 8 mm, the width of the sub-through-hole 414 is 0.4 mm, and the vertical distance from the sub-through-hole 414 to the edge of the suspension member 41, and the distance between two adjacent sub-through-holes 414 in adjacent columns are all 2.4 mm

[0137] The above embodiments introduce the through-hole 410 in various dimensions. This embodiment details the structure of a specific suspension member 41. The through-hole 410 in the suspension member 41 is composed of 4 sub-through-holes 411 arranged in 2 rows and 2 columns. Each sub-through-hole 414 extends along the length direction of the suspension member 41. Two adjacent sub-through-holes 414 in adjacent rows and adjacent columns are arranged in a corresponding manner. Each sub-through-hole is prepared by a stamping process, and each sub-through-hole is a racetrack-shaped hole

[0138] And along the length direction, the length of the suspension member 41 (as shown by L in Figure 7 ) is 20.9 mm, the vertical distance from the sub-through-hole 414 to the edge of the suspension member 41 (as shown by L1 in Figure 7 ), the length of the sub-through-hole 414 (as shown by L2 in Figure 7 ), and the distance between two adjacent sub-through-holes 414 in adjacent rows (as shown by L3 in Figure 7 ) are all 4 mm. Along the width direction, the width of the suspension member 41 (as shown by D in Figure 7 ) is 8 mm, the vertical distance from the sub-through-hole 414 to the edge of the suspension member 41 (as shown by D1 in Figure 7 ), and the distance between two adjacent sub-through-holes 414 in adjacent columns (as shown by D3 in Figure 7 ) are all 2.4 mm, and the width of the sub-through-hole 414 (as shown by D2 in Figure 7 ) is 0.4 mm

[0139] With the above settings, the suspension member 41 can not only absorb internal stress and avoid stress concentration, but also endow the suspension member 41 with excellent strength and flexibility, excellent comprehensive performance, and avoid plastic deformation or even fracture during dropping.

[0140] The above text has introduced in detail the various parameters of the through hole 410 in the suspension member 41 and the unexpected technical effects brought about. Next, other structural features in the motor 1 will be further introduced.

[0141] Please refer to Figure 2 、 Figures 4 - 5 、and Figures 8 - 9 , Figure 8 which are Figure 4 partial enlarged views of the motor shown. Figure 9 which are Figure 1 partial enlarged views of the motor shown. In this embodiment, the driving assembly 20 includes a base 21 and a driving member 22. The driving member 22 is connected to the base 21. The suspension assembly 40 further includes a first clamping member 42, a second clamping member 43, a third clamping member 44, a first fixing member 45, and a second fixing member 46. The first clamping member 42 and the second clamping member 43 are disposed on opposite sides of one end of the suspension member 41. The first fixing member 45 passes through the first clamping member 42, one end of the suspension member 41, and the second clamping member 43 and is fixed. The first clamping member 42, one end of the suspension member 41, and the second clamping member 43 are also connected to one side of the base 21.

[0142] The other end of the suspension member 41 is disposed on the frame 10. The third clamping member 44 is disposed at the other end of the suspension member 41 away from the frame 10. The second fixing member 46 passes through the third clamping member 44, the other end of the suspension member 41, and the frame 10 and is fixed. Among them, the material of the frame 10 is different from that of the suspension member 41.

[0143] The driving assembly 20 is composed of a base 21 and a driving member 22. The base 21 is used to install and carry the driving assembly 20 and the motion module 30a, and even other components. The driving member 22 is used to generate an electromagnetic effect and can be connected to the base 21 in various ways. For example, the driving member 22 can be fixedly connected to the base 21. Optionally, the number of driving members 22 can be 2, and the two driving members 22 are arranged along the moving direction. Further optionally, each driving member 22 includes a winding frame 221 and a winding 222. The winding frame 221 is mainly used to connect to the base 21 and wind the winding 222. The winding frame 221 includes but is not limited to an iron core. The winding 222 includes but is not limited to copper wire, and the copper wire can be a flat wire.

[0144] In addition to the suspension member 41, the suspension assembly 40 may further include a first clamping member 42, a second clamping member 43, a third clamping member 44, a first fixing member 45, and a second fixing member 46. The various clamping members in the suspension assembly 40 are mainly used to clamp the suspension member 41 to clamp and fix the suspension member 41. One end of the suspension member 41, such as the lower end, can be close to the base 21, and the other end of the suspension member 41, such as the upper end, can be close to the frame 10. For one end of the suspension member 41, the first clamping member 42 and the second clamping member 43 can be arranged on opposite sides of one end of the suspension member 41, and the suspension member 41 is clamped by the two clamping members to facilitate better fixation. And then the first fixing member 45 passes through the first clamping member 42, one end of the suspension member 41, and the second clamping member 43, so as to fix the first clamping member 42, one end of the suspension member 41, and the second clamping member 43 together with the first fixing member 45. Subsequently, the fixed first clamping member 42, one end of the suspension member 41, and the second clamping member 43 are connected to one side of the base 21 in various ways, for example, they can be welded to one side of the base 21.

[0145] For the other end of the suspension member 41, since the material of the frame 10 is different from that of the suspension member 41, they cannot be directly welded together, and even if welded, the welding stability is poor. Optionally, the material of the frame 10 is a zinc alloy material, and the materials of the suspension member 41 and various clamping members are stainless steel. Therefore, in this embodiment, the other end of the suspension member 41 is arranged on the frame 10, and only the third clamping member 44 is arranged on the other end of the suspension member 41 facing away from the frame 10, and then the second fixing member 46 passes through the third clamping member 44, the other end of the suspension member 41, and the frame 10, so as to fix the third clamping member 44, the other end of the suspension member 41, and the frame 10 together with the second fixing member 46 to achieve a stable connection.

[0146] In addition, in this embodiment, only one clamping member is adopted at the other end of the suspension member 41, and the frame 10 can act as another clamping member to clamp the opposite sides of the suspension member 41 to clamp and fix the suspension member 41. Thereby, the overall thickness at the other end of the suspension member can be reduced, so as to reserve sufficient distance between the suspension member and the motion module 30a to prevent interference between the two during movement.

[0147] Optionally, the frame 10 has an inner side wall, and the inner side wall of the frame 10 and the third clamping member 44 are located on opposite sides of the other end of the suspension member 41. It can be understood that the inner side wall of the frame 10 acts as a clamping plate to cooperate with the third clamping member 44 and the second fixing member 46 to clamp and fix the suspension member 41.

[0148] Optionally, the first fixing member 45 and the second fixing member 46 include but are not limited to rivets. Using rivets to fixedly connect the suspension member 41 has the advantages of simple installation and firm connection.

[0149] Please refer to Figure 8 and Figures 10 - 11 , Figure 10 which is a partial three-dimensional structural schematic diagram when the base and the suspension assembly cooperate in an embodiment of the present application. Figure 11 is Figure 10 a partial cross-sectional schematic diagram when the base and the suspension assembly shown cooperate. In this embodiment, the first fixing member 45 includes a first through portion 450, and a first fixing portion 451 and a second fixing portion 452 provided on opposite sides of the first through portion 450. The first through portion 450 penetrates through the first clamping member 42, one end of the suspension member 41, and the second clamping member 43. The first fixing portion 451 is provided on the side of the first clamping member 42 away from the suspension member 41, and the second fixing portion 452 is provided on the side of the second clamping member 43 away from the suspension member 41, and the first fixing portion 451 is closer to the base 21 than the second fixing portion 452. The first clamping member 42, one end of the suspension member 41, and the second clamping member 43 are all provided with first connection holes 47.

[0150] The outer side wall of the base 21 is provided with a first protruding portion 212. The first protruding portion 212 is disposed in the first connection hole 47 and welded to the second clamping member 43. And there is a distance between the first fixing portion 451 and the base 21. The cross-sections of the first connection hole 47 and the first protruding portion 212 are non-circular.

[0151] The first fixing member 45 can be composed of a first through portion 450 in the middle, and a first fixing portion 451 and a second fixing portion 452 at both ends. The first through portion 450 is used to penetrate through the first clamping member 42, one end of the suspension member 41, and the second clamping member 43. The first fixing portion 451 and the second fixing portion 452 respectively protrude from the first clamping member 42 and the second clamping member 43. For example, the first fixing portion 451 is provided on the side of the first clamping member 42 away from the suspension member 41, and the second fixing portion 452 is provided on the side of the second clamping member 43 away from the suspension member 41. Optionally, the first fixing member 45 is in a dumbbell shape, that is, the outer diameter of the first fixing portion 451 and the outer diameter of the second fixing portion 452 are greater than the outer diameter of the first through portion 450, which can improve the connection effect. And the first fixing portion 451 is closer to the base 21, and the second fixing portion 452 is farther from the base 21, that is, the first fixing portion 451 is arranged inward, and the second fixing portion 452 is arranged outward. Additionally, first connection holes 47 can be opened in the first clamping member 42, one end of the suspension member 41, and the second clamping member 43.

[0152] On the outer sidewall of the base 21, a first protruding portion 212 may be provided. In other words, the first protruding portion 212 is thickened so that the first protruding portion 212 is away from the outer sidewall of the base 21. Thus, when the first protruding portion 212 is disposed in the first connection hole 47 and the second clamping member 43 is welded, a certain distance can be ensured between the first fixing portion 451 closer to the base 21 and the outer sidewall of the base 21, avoiding interference between the first fixing portion 451 and the base 21.

[0153] It should be noted that by welding the second clamping member 43 to the first protruding portion 212, the suspension assembly 40 can be fixedly connected to the base 21, and the second clamping member 43 disposed on the outside is also convenient for welding with the first protruding portion 212, which can reduce the welding difficulty. Of course, in other embodiments, the first clamping member 42 disposed closer to the inside can also be welded to the first protruding portion 212 to further improve the connection performance. However, the suspension member 41 will not be welded to the first protruding portion 212. The purpose of setting the clamping member in this embodiment is to transfer the welding part, avoid welding the suspension member 41, and prevent the suspension member 41 from being deformed by heat due to welding, thereby affecting properties such as stress and elasticity, and further affecting the vibration damping performance.

[0154] Optionally, the first protruding portion 212 can be directly provided on the outer sidewall of the base 21, or a fixing seat 211 can be first provided on the outer sidewall of the base 21, and then the first protruding portion 212 can be provided on the side of the fixing seat 211 away from the base 21, so as to use the fixing seat 211 to make the first protruding portion 212 away from the base 21, further ensuring a certain distance between the first fixing portion 451 and the outer sidewall of the base 21, and avoiding interference between the first fixing portion 451 and the base 21.

[0155] In addition, in this embodiment, the cross-sections of the first connection hole 47 and the first protruding portion 212 can be non-circular. Compared with the circular first connection hole 47 and the first protruding portion 212, in this embodiment, only one set of the first connection hole 47 and the first protruding portion 212 can be used to achieve positioning. Optionally, the cross-sections of the first connection hole 47 and the first protruding portion 212 are rectangular, and the rectangular plane is more conducive to size detection and CNC machining when precise positioning is required.

[0156] Please refer to Figure 2 together with Figure 8, in this embodiment, the driving component 20 includes a base 21 and a driving member 22. The driving member 22 is connected to the base 21. The motion module 30a includes a motion component 30 and a support component 50. One end of the support component 50 is connected to the base 21, and the other end is connected to the motion component 30. The motion component 30 is disposed on the side of the driving member 22 away from the base 21. The support component 50 includes a support member 51, a fourth clamping member 52, a fifth clamping member 53, and a third fixing member 54. The fourth clamping member 52 and the fifth clamping member 53 are disposed on opposite sides of one end of the support member 51. The third fixing member 54 passes through the fourth clamping member 52, one end of the support member 51, and the fifth clamping member 53 and is fixed. The fourth clamping member 52, one end of the support member 51, and the fifth clamping member 53 are fixed to the base 21.

[0157] The distance between the support component 50 and the suspension component 40 is less than a preset distance. The other end of the support member 51 is provided with a second connection hole 510. The motion component 30 is provided with a second protrusion 300. The second protrusion 300 is disposed in the second connection hole 510 and welds to the other end of the support member 51. The cross-sections of the second connection hole 510 and the second protrusion 300 are non-circular.

[0158] The base 21 and the driving member 22 have been introduced in detail above, and will not be elaborated in this embodiment. The motion module 30a includes a motion component 30 and a support component 50. The support component 50 is mainly used to support the motion component 30. One end of the support component 50 can be connected to the base 21 in various ways, and the other end can be connected to the motion component 30 in various ways. For example, one end of the support component 50 can be welded to the base 21, and the other end can be welded to the motion component 30. The motion component 30 is disposed on the side of the driving member 22 away from the base 21, that is, the motion component 30 is disposed above the driving member 22.

[0159] The motion component 30 and the driving member 22 cooperate with each other to perform reciprocating movement. For example, the motion component 30 includes a motion seat 31 and a permanent magnet 32. The permanent magnet 32 is fixedly disposed on the side of the motion seat 31 adjacent to the driving member 22, that is, the permanent magnet 32 is fixed under the motion seat 31. When the driving member 22 works, the magnetic poles can change periodically. Therefore, the driving member 22 and the permanent magnet 32 with fixed magnetic poles can cooperate with each other to achieve reciprocating movement. The driving member 22 drives the base 21 to reciprocate, and the permanent magnet 32 drives the motion seat 31 to reciprocate. During the movement of the motion component 30, the vibration is transmitted to the base 21 through the support component 50. The support component 50 itself also has a certain elasticity and toughness, so the vibration can be reduced to a certain extent.

[0160] Optionally, there is a distance between the motion component 30 and the driving member 22 to avoid contact and friction between the two, and reduce the movement effect.

[0161] Optionally, the number of the support components 50 may be one or more. In this embodiment, only two support components 50 are schematically illustrated, and the two support components 50 are connected to opposite ends of the motion component 30.

[0162] The support component 50 includes a support member 51, a fourth clamping member 52, a fifth clamping member 53, and a third fixing member 54. The support member 51 is mainly used to connect the base 21 and the motion component 30 to play a supporting role. The number of the support members 51 may be one or more. In this embodiment, only two support members 51 are schematically illustrated. The various clamping members in the support component 50 are mainly used to clamp the support member 51 to clamp and fix the support member 51. One end of the support member 51, such as the lower end, may be close to the base 21, and the other end of the support member 51, such as the upper end, may be close to the motion component 30. For one end of the support member 51, the fourth clamping member 52 and the fifth clamping member 53 may be arranged on opposite sides of one end of the support member 51, and the support member 51 is clamped by the two clamping members to facilitate better fixing. Then, the third fixing member 54 penetrates through the fourth clamping member 52, one end of the support member 51, and the fifth clamping member 53, so that the fourth clamping member 52, one end of the support member 51, and the fifth clamping member 53 are fixed to the third fixing member 54 together. Subsequently, the fixed fourth clamping member 52, one end of the support member 51, and the fifth clamping member 53 are fixed to the base 21, for example, they may be welded to the base 21.

[0163] For the other end of the support member 51, the distance between the support component 50 and the suspension component 40 is less than a preset distance, that is, the distance between the support component 50 and the suspension component 40 is too small, resulting in no clamping member being provided at the other end of the support member 51. Optionally, the preset distance is 2.5 mm - 3 mm. A second connection hole 510 is provided at the other end of the support member 51, and a second protrusion 300 is provided on the motion component 30. The second protrusion 300 may be arranged in the second connection hole 510, and the second protrusion 300 is welded to the other end of the support member 51 to weld the support member 51 to the motion component 30. In addition, in this embodiment, the cross-sections of the second connection hole 510 and the second protrusion 300 may also be non-circular. Compared with the circular second connection hole 510 and the second protrusion 300, only one set of the second connection hole 510 and the second protrusion 300 can be used to achieve positioning in this embodiment. Optionally, the cross-sections of the second connection hole 510 and the second protrusion 300 are rectangular, and the rectangular plane is more conducive to dimension detection and is more conducive to CNC machining when precise positioning is required.

[0164] Optionally, when the number of the supporting members 51 is plural, the supporting assembly 50 may further include a fourth fixing member 55. The fourth fixing member 55 can penetrate through the other ends of the plurality of supporting members 51 and be fixed, so as to fix the other ends of the plurality of supporting members 51 together and prevent the other ends of the plurality of supporting members 51 from loosening and separating. And when the supporting assembly 50 includes a plurality of supporting members 51, only the outermost supporting member 51, that is, the supporting member 51 away from the driving member 22, is welded to the second protruding portion 300, reducing the welding difficulty.

[0165] It should be noted that, in other embodiments, the motion module 30a may include a motion assembly 30 and a suspension assembly 40. One end of the suspension assembly 40 is connected to the base 21, and the other end is connected to the motion assembly 30. The motion assembly 30 is disposed on the side of the driving member 22 away from the base 21. In other words, in this embodiment, the motion assembly 30 is not connected and supported by the supporting assembly 50. The motion assembly 30 can also be connected through the suspension assembly 40 provided in the above embodiments. For example, the suspension assembly 40 includes a suspension member 41, a first clamping member 42, a second clamping member 43, a third clamping member 44, a first fixing member 45, and a second fixing member 46, etc. The suspension member 41 has the structure of the through hole 410 introduced above. For the specific structures of the suspension member 41 and the suspension assembly 40, reference can be made to the above embodiments, and details are not described herein again.

[0166] Please refer to Figure 10 with Figure 12 , Figure 12 FIG. is a partial cross-sectional view of the base and the supporting assembly in an embodiment of the present application. In this embodiment, the base 21 includes a bottom wall 213. The bottom wall 213 is provided with a positioning hole 2130. The fourth clamping member 52, one end of the supporting member 51, and the fifth clamping member 53 abut against the bottom wall 213 and extend into the positioning hole 2130. And the fourth clamping member 52 and the fifth clamping member 53 are welded to the bottom wall 213 in the positioning hole 2130.

[0167] The base 21 is composed of a bottom wall 213. A positioning hole 2130 can be opened on the bottom wall 213. The fourth clamping member 52, one end of the supporting member 51, and the fifth clamping member 53 can abut against the bottom wall 213. And the lower ends of the fourth clamping member 52, one end of the supporting member 51, and the fifth clamping member 53 can extend into the positioning hole 2130. And the fourth clamping member 52 and the fifth clamping member 53 in the positioning hole 2130 can be welded to the bottom wall 213 to fix one end of the supporting assembly 50 to the base 21, reducing the fixing difficulty and improving the fixing effect. And the positioning hole 2130 can also improve the positioning accuracy of the fourth clamping member 52, one end of the supporting member 51, and the fifth clamping member 53 installed on the bottom wall 213.

[0168] It is worth noting that in this embodiment, only the fourth clamping member 52 and the fifth clamping member 53 are welded to the bottom wall 213, and one end of the support member 51 is not welded to the bottom wall 213. This can prevent the support member 51 from being deformed by heat due to welding, thereby affecting the properties such as stress and elasticity, and thus affecting the vibration reduction performance.

[0169] Optionally, a second guide slope 2131 may be provided on the side of the inner wall of the positioning hole 2130 close to the driving member 22, i.e., the top of the inner wall of the positioning hole 2130, to provide a guiding function when the fourth clamping member 52, one end of the support member 51, and the fifth clamping member 53 are arranged on the base 21.

[0170] Please refer to Figure 10 and Figure 13 , Figure 13 Schematic diagram of a partial cross section of a base and a support assembly in another embodiment of the present application. In this embodiment, the third fixing member 54 includes a second penetration portion 540, and a third fixing portion 541 and a fourth fixing portion 542 disposed on opposite sides of the second penetration portion 540, the second penetration portion 540 penetrates the fourth clamping member 52, one end of the support member 51, and the fifth clamping member 53, the third fixing portion 541 is disposed on a side of the fourth clamping member 52 away from the support member 51, and the fourth fixing portion 542 is disposed on a side of the fifth clamping member 53 away from the support member 51. The base 21 also includes a side wall 214 connected to the bottom wall 213, and the side wall 214 is provided with an avoidance groove 215 and a receiving groove 216. The third fixing portion 541 and the fourth fixing portion 542 are both arranged in the avoidance groove 215, and the fourth clamping member 52, one end of the support member 51, and the fifth clamping member 53 are arranged in the receiving groove 216, and the fourth clamping member 52 and the fifth clamping member 53 are also welded to the side wall 214.

[0171] The third fixing member 54 may be composed of a second through-portion 540 in the middle, and a third fixing portion 541 and a fourth fixing portion 542 at both ends. The second through-portion 540 penetrates the fourth clamping member 52, one end of the support member 51, and the fifth clamping member 53. The third fixing portion 541 and the fourth fixing portion 542 protrude from the fourth clamping member 52 and the fifth clamping member 53, respectively. For example, the third fixing portion 541 is disposed on a side of the fourth clamping member 52 away from the support member 51, and the fourth fixing portion 542 is disposed on a side of the fifth clamping member 53 away from the support member 51. Optionally, the second fixing member 46 is dumbbell-shaped, that is, the outer diameters of the third fixing portion 541 and the fourth fixing portion 542 are larger than the outer diameter of the second through-portion 540, which can improve the connection effect.

[0172] In addition to the bottom wall 213, the base 21 may also include a side wall 214 connected to the bottom wall 213. Since the third fixing portion 541 and the fourth fixing portion 542 protrude from the fourth clamping member 52 and the fifth clamping member 53, the basic implementation method can open an avoidance groove 215 and a receiving groove 216 on the side wall 214. When the fourth clamping member 52, one end of the support member 51, and the fifth clamping member 53 are installed on the bottom wall 213, the protruding third fixing portion 541 and the fourth fixing portion 542 can be arranged in the avoidance groove 215, so that the avoidance groove 215 is used to avoid the third fixing portion 541 and the fourth fixing portion 542, thereby preventing the third fixing member 54 from interfering with the base 21.

[0173] Optionally, a first guiding slope 2141 may be provided on a side of the side wall 214 facing away from the bottom wall 213 to provide a guiding function when the fourth clamping member 52 , one end of the support member 51 , and the fifth clamping member 53 are disposed on the base 21 .

[0174] In addition, when the fourth clamping member 52, one end of the support member 51, and the fifth clamping member 53 abut against the bottom wall 213, the fourth clamping member 52, one end of the support member 51, and the fifth clamping member 53 can be arranged in the accommodating groove 216, and the fourth clamping member 52 and the fifth clamping member 53 can be welded to the side wall 214, and one end of the support member 51 is not welded to the side wall 214, thereby preventing the support member 51 from being deformed by heat due to welding, thereby affecting the properties such as stress and elasticity, and thus affecting the vibration reduction performance.

[0175] Please refer again Figure 3 In this embodiment, the frame 10 is provided with a first observation hole 101, and the first observation hole 101 is used to expose at least part of the support assembly 50, and the area of ​​the first observation hole 101 is smaller than the preset area, so that the suspension assembly 40 and the first observation hole 101 are staggered.

[0176] A first observation hole 101 may be provided on the frame 10, and the first observation hole 101 may expose at least part of the support assembly 50, which not only reduces the weight of the frame 10, but also allows the user to observe the movement process of the support assembly 50 through the first observation hole 101, so as to visualize the movement process and enhance the sense of technology. In addition, the first observation hole 101 may be used to observe whether the support assembly 50 is deformed or damaged, so as to facilitate timely maintenance.

[0177] In addition, the area of ​​the first observation hole 101 is smaller than the preset area, that is, the size of the first observation hole 101 is not too large, and the suspension assembly 40 and the first observation hole 101 are staggered, that is, the first observation hole 101 does not expose the suspension assembly 40. In this way, firstly, the support assembly 50 is exposed, and it is sufficient to observe the support assembly 50, and secondly, it is avoided that the first observation hole 101 is too large to reduce the strength of the frame 10.

[0178] Optionally, a second observation hole 102 is further provided on the rack 10. The second observation hole 102 is used to expose a part of the driving member 22, and the user can also observe the reciprocating movement of the driving member 22.

[0179] Further optionally, the number of the first observation holes 101 is two. The two first observation holes 101 are arranged on opposite sides of the second observation hole 102. One first observation hole 101 is used to expose one support assembly 50, and the other first observation hole 101 is used to expose the other support assembly 50.

At this time, the hair trimmer 5 can also be called an electric shaver.

[0182] The hair trimmer 5 mainly includes a housing 2, a transmission assembly 3, a cutter head 4, and a motor 1. The housing 2 is mainly used to install the remaining components of the hair trimmer 5. For example, the housing 2 includes a main housing and an end cover. The motor 1 is arranged inside the main housing. The main housing is provided with an opening, and the end cover is arranged at the opening and connected to the main housing. The top of the rack 10 in the motor 1 is connected to the end cover to transmit the vibration upward and reduce the vibration feeling when the user holds it.

[0183] The transmission assembly 3 is connected to the motion module 30a. When the motion module 30a reciprocates, it can synchronously drive the transmission assembly 3 to reciprocate. The cutter head 4 is connected to the transmission assembly 3. When the transmission assembly 3 reciprocates, it can synchronously drive the cutter head 4 to reciprocate, so as to achieve the purpose of trimming hair.

[0184] The hair trimmer 5 of the present embodiment adopts the motor 1 provided by the above embodiment. First, by adding a suspension assembly 40, one end of the suspension assembly 40 is connected to the drive assembly 20, and the other end is connected to the frame 10. Since the suspension assembly 40 itself has a certain elasticity and flexibility, the suspension assembly 40 can be used to absorb part of the vibration generated when the drive assembly 20 and the motion module 30a reciprocate, improving the vibration damping effect. Second, compared with a whole and non-perforated suspension member 41, opening a through hole 410 in the suspension member 41 can reduce the internal stress of the suspension member 41 and reduce the stress concentration generated during the assembly process of the suspension member 41, thereby causing local deformation of the suspension member 41. Third, the through hole 410 can extend vertically along the direction from the first side 412 to the second side 413 of the suspension member 41. Compared with the horizontally extending through hole 410, the strength of the suspension member 41 can be improved, avoiding bending deformation of the suspension member 41 caused by the whole machine falling, and improving the anti-drop performance. In addition, there are gaps between the through hole 410 and the first side 412 and the second side 413, so that the through hole 410 only penetrates the opposite two surfaces in the thickness direction of the suspension member 41, and does not penetrate the opposite two surfaces in the length direction of the suspension member 41. Compared with the through hole 410 that not only penetrates the opposite two surfaces in the thickness direction of the suspension member 41 but also penetrates one surface in the length direction of the suspension member 41, the present application can further improve the strength of the suspension member 41 and avoid bending deformation during falling.

[0185] In summary, by adding the suspension assembly 40 in the present embodiment, the vibration can be reduced. Opening a through hole 410 with a specific structure in the suspension member 41 of the suspension assembly 40 can reduce the stress concentration, improve the strength, avoid falling deformation, and improve the anti-drop performance.
