[0038] The motor and hair trimmer provided in this application, firstly, by adding a suspension assembly, one end of which is connected to the drive assembly and the other end to the frame, can absorb some of the vibrations generated during the reciprocating movement of the drive assembly and motion module, thus improving vibration reduction. Secondly, compared to a single, unperforated suspension component, the through-holes in the suspension component reduce internal stress and minimize stress concentration during assembly, preventing localized deformation. Thirdly, the through-holes extend vertically along the direction from the first to the second side of the suspension component, which increases its strength compared to laterally extending through-holes, preventing bending deformation due to drops and improving drop resistance. Furthermore, the through-holes are spaced from both the first and second sides, ensuring that they penetrate only the opposite surfaces in the thickness direction of the suspension component, not in the length direction. Compared to a through hole that penetrates not only both sides of the suspension component in the thickness direction but also one side of the suspension component in the length direction, this application can further improve the strength of the suspension component and prevent bending deformation when it falls.

[0039] In summary, this application can reduce vibration by adding a suspension assembly, and by opening through holes with a specific structure on the suspension components in the suspension assembly, stress concentration can be reduced, strength can be increased, drop deformation can be avoided, and drop resistance can be improved.

Detailed Implementation

[0058] The following are preferred embodiments of this application. It should be noted that, for those skilled in the art, several improvements and modifications can be made without departing from the principles of this application, and these improvements and modifications are also considered to be within the scope of protection of this application.

[0059] In view of this, and to solve the above problems, this application provides a motor and a hair trimmer. Please refer to them together.

[0060] The motor 1 provided in this embodiment includes a frame 10, a drive assembly 20, a motion module 30a, and a suspension assembly 40. At least a portion of the drive assembly 20, at least a portion of the motion module 30a, and at least a portion of the suspension assembly 40 are all disposed within the frame 10. The motion module 30a is connected to one side of the drive assembly 20. The drive assembly 20 and the motion module 30a cooperate with each other to reciprocate along a direction perpendicular to the arrangement of the drive assembly 20 and the motion module 30a. One end of the suspension assembly 40 is connected to the drive 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 has a through hole 410 along its thickness direction. Along the arrangement direction of the drive assembly 20 and the motion module 30a, the suspension member 41 includes a first side 412 and a second side 413 disposed opposite to each other. The through hole 410 extends along the direction from the first side 412 to the second side 413 and has a gap between it and both the first side 412 and the second side 413.

[0061] The motor 1 provided in this embodiment is mainly used in various devices that need to move back and forth, such as personal cleaning devices, household electronic devices and other small appliances. This embodiment only uses the hair trimmer 5 in personal cleaning devices as an example for illustration.

[0062] The frame 10 primarily serves to provide a mounting base for other components of the motor 1, such as at least a portion of the drive assembly 20, at least a portion of the motion module 30a, and at least a portion of the suspension assembly 40, all of which are housed within the frame 10. It is noteworthy that the drive assembly 20, motion module 30a, and suspension assembly 40 may be partially housed within the frame 10, with the remainder located outside the frame 10, or all three components may be housed entirely within the frame 10. Furthermore, the entire motor 1 can subsequently be mounted onto the housing 2 of the hair trimmer 5 via the frame 10.

[0063] The drive component 20 primarily functions as a drive unit. When powered on, it generates an electromagnetic field. The motion module 30a is connected to the drive component 20 and positioned to one side of it, for example, arranged vertically alongside the drive component 20. The drive component 20 and motion module 30a work together to reciprocate along a direction perpendicular to their arrangement; that is, both can reciprocate laterally. Specifically, the motion module 30a can reciprocate laterally under the electromagnetic effect of the drive component 20, and it can also cause the drive component 20 to reciprocate laterally.

[0064] Optionally, the movement direction of the motion module 30a and the drive component 20 can be the same or opposite. When the movement direction of the motion module 30a and the drive component 20 is opposite, they can cancel each other out and reduce the vibration of the motor 1.

[0065] Optionally, a drive component 20 and a motion module 30a form a motion module. The motor 1 includes at least one motion module. This embodiment is illustrated only with two motion modules, and the two motion modules are arranged along the direction of movement perpendicular to the drive component 20 and the motion module 30a.

[0066] Alternatively, the two motion modules can move in the same or opposite directions. When the two motion modules move in opposite directions, they can further cancel each other out and further reduce the vibration of motor 1.

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

[0068] Optionally, since users typically hold the device in the middle or lower-middle part, the other end of the suspension assembly 40 can be connected to the top of the frame 10, with a gap between the drive assembly 20 and the bottom of the frame 10, thus providing a suspension function. This allows the vibration of the drive assembly 20 to be transmitted upwards instead of downwards, reducing the user's perceived vibration and improving user comfort.

[0069] It is worth noting that the suspension function mentioned in this embodiment refers to the situation where the housing 2 of the hair trimmer 5 is placed on a table, the ground, etc., with the blade 4 facing upwards. In this case, the suspension assembly 40 can play a suspension role in the direction of gravity, hence the name suspension assembly 40. When the motor 1 or even the hair trimmer 5 adopts other placement methods, the suspension assembly 40 can be called a connecting assembly.

[0070] Optionally, each drive assembly 20 is connected in conjunction with two suspension assemblies 40. Specifically, along the reciprocating direction of the drive assembly 20, the two suspension assemblies 40 are connected to opposite ends of the drive assembly 20 to improve the symmetry and stability of the structure. Of course, in other embodiments, each drive assembly 20 may also be connected in conjunction with one suspension assembly 40, three suspension assemblies 40, or even more suspension assemblies 40.

[0071] The suspension assembly 40 mainly includes a suspension member 41. The remaining components of the suspension assembly 40 will be described in detail later. The suspension function of the suspension member 41 and the suspension assembly 40 is only relevant to a specific placement method and can be understood similarly to the above description; it will not be repeated here. The suspension member 41 is a thin, sheet-like structural component. One end of the suspension member 41 can be connected to the drive assembly 20, and the other end is connected to the frame 10. Therefore, the suspension member 41 itself has a certain degree of elasticity and flexibility, and can undergo a certain degree of elastic bending and deformation, thereby absorbing some of the vibrations generated during reciprocating movement. The number of suspension members 41 can be one or more; this embodiment only illustrates three suspension members 41.

[0072] Since the suspension component 41 needs to be connected to the drive assembly 20 and the frame 10, regardless of the connection method used, such as riveting, a through hole 411 will be opened on the suspension component 41, and the rivet will be connected and fixed through the through hole 411. Due to the manufacturing tolerances of the suspension component 41 itself and the assembly tolerances during connection, the suspension component 41 will generate a certain internal stress after connection, that is, the suspension component 41 will experience stress concentration, which will cause the suspension component 41 to warp or arch locally, or the suspension component 41 will be more prone to plastic bending when the whole machine is dropped, thereby reducing the vibration damping effect and even affecting the reciprocating movement of the drive assembly 20 and the motion module 30a. Therefore, this embodiment reduces the internal stress of the suspension component 41 by opening a through hole 410 in the thickness direction of the suspension component 41, reducing the stress concentration generated in the suspension component 41 during assembly, thereby reducing the local deformation of the suspension component 41. Among them, such as Figures 6-7 As shown, the thickness direction of the suspension member 41 can be understood as the reciprocating movement direction of the drive assembly 20 and the motion module 30a. In addition, the direction along which the drive assembly 20 and the motion module 30a are arranged can also be understood as the length direction of the suspension member 41, and similarly, the direction perpendicular to the direction of the drive assembly 20 and the motion module 30a can also be understood as the width direction of the suspension member 41.

[0073] Along the length of the suspension member 41, the suspension member 41 includes a first side 412 and a second side 413 arranged opposite to each other, i.e., an upper side or a lower side. This embodiment does not specify which side is upper or lower. The direction from the first side 412 to the second side 413 is the same as the arrangement direction of the drive assembly 20 and the motion module 30a, and is also understood as the length direction of the suspension member 41. In this embodiment, the through hole 410 can be vertically extended vertically along the length of the suspension member 41. Compared to a through hole 410 extending horizontally along the width direction, a vertically extended through hole 410 can alleviate stress concentration and improve the strength of the suspension member 41, preventing bending and deformation of the suspension member 41 due to a drop, and improving drop resistance.

[0074] Furthermore, when the through hole 410 extends vertically, it does not penetrate both the upper and lower sides, i.e., the first side 412 and the second side 413, but rather maintains a certain distance from both sides. In other words, 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 to a situation where the through hole 410 penetrates not only the opposite two surfaces in the thickness direction of the suspension member 41, but also one surface in the length direction of the suspension member 41, the shape of the suspension member 41 is U-shaped. This application can further improve the strength of the suspension member 41, prevent bending deformation during drops, and further improve drop resistance.

[0075] In summary, this embodiment can reduce vibration by adding a suspension assembly 40. By opening a through hole 410 with a specific structure on the suspension member 41 in the suspension assembly 40, stress concentration can be reduced, strength can be increased, drop deformation can be avoided, and drop resistance can be improved.

[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, and the vertical distance from the through hole 410 to the edge of the suspension member 41 along the length direction is 15%-25% of the length of the suspension member 41. The suspension member 41 also has a width direction perpendicular to the first side 412 to the second side 413, and the vertical distance from the through hole 410 to the edge of the suspension member 41 along the width direction is 20%-40% of the width of the suspension member 41.

[0077] As can be seen from the above, there is a gap 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 between the through hole 410 and the edge of the suspension member 41 (i.e., the first side 412 or the second side 413) can be made (e.g., ...). Figure 7 As shown in L1, the length of the suspension component 41 is (e.g., ...). Figure 7The 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. If the vertical distance from the through hole 410 to the edge of the suspension member 41 is too small, for example, less than 15%, the through hole 410 is too close to the edge of the suspension member 41 along its length. The strength at this edge is too low, making it prone to plastic bending deformation and resulting in poor drop resistance, failing to meet the drop resistance requirements. If the vertical distance from the through hole 410 to the edge 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 number of through holes 410. This reduces the flexibility of the suspension member 41, preventing it from fully releasing internal stress and reducing the vibration damping effect.

[0078] In summary, by making the vertical distance between the through hole 410 and the edge of the suspension member 41 15%-25% of the length of the suspension member 41, this embodiment can make the suspension member 41 have excellent strength and drop resistance, and can fully absorb internal stress, avoid stress concentration, and improve the vibration reduction effect.

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

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

[0081] Optionally, the length of the suspension member 41 is 15mm-30mm. More optionally, the length of the suspension member 41 can be 15mm, 20mm, 25mm, 30mm, 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 (e.g.) Figure 7 As shown in D1, the width of the suspension component 41 is (e.g., ...). Figure 7The 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. If the vertical distance from the through hole 410 to the edge of the suspension member 41 is too small, for example, less than 20%, the through hole 410 will be too close to the edge of the suspension member 41 in the width direction. The strength at this edge will be too low, making it prone to plastic bending deformation and resulting in poor drop resistance, failing to meet the drop resistance requirements. Furthermore, the impact of being too close to the edge in the width direction on the strength reduction will be greater than that in the length direction. If the vertical distance from the through hole 410 to the edge 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 number of through holes 410, or too small a distance between two adjacent sub-through holes 414. This will not only reduce the strength but also reduce the flexibility of the suspension member 41, preventing the suspension member 41 from fully releasing internal stress and reducing the vibration damping effect.

[0083] In summary, by making the vertical distance between the through hole 410 and the edge of the suspension member 41 20%-40% of the width of the suspension member 41, this embodiment can give the suspension member 41 excellent strength and drop resistance, and can fully absorb internal stress, avoid stress concentration, and improve the vibration reduction effect.

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

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

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

[0087] It is worth noting that in this embodiment, only the proportional relationship in the length direction, or only the proportional relationship in the width direction, or both the proportional relationship in the length direction and the proportional relationship in the width direction may be satisfied.

[0088] In this embodiment, the suspension member 41 has a length direction along the first side 412 to the second side 413, and the angle between the extension direction of the through hole 410 and the length direction is 0°-10°. When the angle between the extension direction of the through hole 410 and the length direction is 0°, the through hole 410 extends vertically. When the angle between the extension direction of the through hole 410 and the length direction is greater than 0°, the through hole 410 can be set slightly inclined on the basis of vertical extension. If the angle of inclination 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 failing to meet the drop test requirements.

[0089] In summary, by making the angle between the extension direction and the length direction of the through hole 410 0°-10°, this embodiment can enable the suspension member 41 to have excellent strength while solving stress concentration. This embodiment is only illustrated with the example of the angle between the extension direction and the length direction of the through hole 410 being 0°.

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

[0091] In this embodiment, the total area of ​​the through holes 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 illustrated only by the sum of the areas of four sub-through holes 414. This embodiment allows the total area of ​​the through holes 410 to be 2%-5% of the area of ​​the suspension member 41. If the proportion of the total area of ​​the through holes 410 to the area of ​​the suspension member 41 is too small, for example, less than 2%, it will not only result in an insufficient number of sub-through holes 414, failing to solve the stress concentration problem, but also make the area of ​​each sub-through hole 414 too small, increasing manufacturing difficulty. If the proportion of the total area of ​​the through holes 410 to the area of ​​the suspension member 41 is too large, for example, greater than 5%, it will make the total area of ​​the through holes 410 too large, reducing the overall strength of the suspension member 41.

[0092] In summary, by making the total area of ​​the through hole 410 2%-5% of the area of ​​the suspension member 41, this embodiment not only solves the stress concentration problem of the suspension member 41, but also enables the suspension member 41 to 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 5 mm². 2 -8mm 2Alternatively, the total area of ​​the through-hole 410 can be 5 mm². 2 6mm 2 7mm 2 8mm 2 wait.

[0095] Optionally, the area of ​​the suspension element 41 is 150 mm². 2 -200mm 2 Alternatively, the area of ​​the suspension element 41 can be 150 mm². 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 the total length of the through hole 410 along the length direction is 10%-90% 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, and the total width of the through hole 410 along the width direction is 3%-40% of the width of the suspension member 41.

[0097] Based on the premise that the total area of ​​the through hole 410 is 2%-5% of the area of ​​the suspension member 41, this 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 (as shown in L) is 10%-90% of the total length 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 two sub-through holes 414 (e.g., ...). Figure 7 The sum of the lengths shown in L2 is used for illustrative purposes. If the total length of the through hole 410 is too small to account for the length of the suspension member 41, for example, less than 10%, the vertical extension dimension of the through hole 410 will be too small, failing to solve the stress concentration problem, and the flexibility of the suspension member 41 will also decrease, weakening the vibration damping effect. If the total length of the through hole 410 is too large to account for the length of the suspension member 41, for example, greater than 90%, the length of the through hole 410 will be too long, with the through hole 410 being opened in most of the length direction of the suspension member 41, which will reduce the strength of the suspension member 41.

[0098] In summary, by making the total length of the through hole 410 10%-90% of the length of the suspension member 41, this embodiment can enable the suspension member 41 to not only solve the stress concentration problem, but 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 3mm-18mm. More optionally, the total length of the through hole 410 can be 3mm, 6mm, 9mm, 12mm, 15mm, 18mm, etc.

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

[0102] Similarly, in the width direction, the total width of the through hole 410 can be equal to the width of the hanging member 41 (e.g., Figure 7 The total width of the through hole 410 (as shown in Figure D) is 3%-40%. This 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 the width of two sub-through holes 414 (e.g., ...). Figure 7 The sum of the values ​​shown in Figure D2 is used for illustrative purposes. If the total width of the through hole 410 is too small as a percentage of the width of the suspension member 41 (e.g., less than 3%), the size of the through hole 410 will be too small, increasing the manufacturing difficulty. If the total width of the through hole 410 is too large as a percentage of the width of the suspension member 41 (e.g., greater than 40%), the distance the through hole 410 extends in the width direction will be too long, further reducing the strength of the suspension member 41. Furthermore, actual testing shows that when the through hole 410 extends the same distance in both the length and width directions, the reduction in strength is more pronounced in the width direction.

[0103] In summary, by making the total width of the through hole 410 3%-40% of the width of the suspension member 41, this embodiment not only reduces the difficulty of manufacturing the through hole 410, but also gives the suspension member 41 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 0.3mm-3mm. More optionally, the total width of the through hole 410 can be 0.3mm, 0.5mm, 1mm, 1.5mm, 2mm, 2.5mm, 3mm, etc.

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

[0107] It is worth noting that in this embodiment, only the proportional relationship in the length direction, or only the proportional relationship in the width direction, 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 suspension member 41 has a length direction along the first side 412 to the second side 413 and a width direction perpendicular to the first side 412 to the second side 413. Along the length direction, the number of rows of the at least one sub-through hole 414 is 1 to 3. Along the width direction, the number of columns of the at least one sub-through hole 414 is 1 to 3.

[0109] A through-hole 410 can be composed of at least one sub-through-hole 414; in other words, a through-hole 410 is a collection of at least one sub-through-hole 414. When there are multiple sub-through-holes 414, they are not randomly arranged but arranged in an array. Specifically, the number of rows of at least one sub-through-hole 414 in the length direction is 1 to 3 rows. In the width direction, the number of columns of at least one sub-through-hole 414 is 1 to 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, multiple sub-through-holes 414 can also be arranged as 2 rows * 3 columns, 3 rows * 1 column, etc. This embodiment is only illustrated using 2 rows * 2 columns.

[0110] In summary, by arranging at least one sub-through hole 414 in an array according to the above arrangement, the uniformity of the overall strength of the suspension component 41 can be improved, and the internal stress can be absorbed at all points of the suspension component 41, thus 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 sub-through holes 414 in adjacent rows is 15%-25% of the length of the suspension member 41; the distance between two sub-through holes 414 in adjacent columns is 20%-40% of the width of the suspension member 41.

[0112] Among multiple sub-through holes 414 in the same column, the distance between two sub-through holes 414 in adjacent rows (e.g. Figure 7As shown in L3, the distance between the two sub-through holes 414 in the first row and the two sub-through holes 414 in the second row is 15%-25% of the length of the suspension member 41. For example, the distance between the two sub-through holes 414 in the second row and the two sub-through holes 414 in the third row is 15%-25% of the length of the suspension member 41. If the distance between the two sub-through holes 414 in adjacent rows is too small as a percentage of the length of the suspension member 41, for example, less than 15%, the distance between the two sub-through holes 414 in adjacent rows will be too small and they will be set too close together. This will not only reduce the strength of the suspension member 41, but may even cause the suspension member 41 between the two sub-through holes 414 in adjacent rows to break. If the distance between two sub-through holes 414 in an adjacent row is too large as a proportion of the length of the suspension 41, for example, greater than 25%, the distance between the two sub-through holes 414 in an adjacent row will be too large, thereby reducing the length of each sub-through hole 414. This will result in the through hole 410 having too small a vertical extension dimension, which will not be able to solve the problem of stress concentration. Furthermore, the flexibility of the suspension 41 will also be reduced, and the vibration reduction effect will be weakened.

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

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

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

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

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

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

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

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

[0122] It is worth noting that in this embodiment, only the proportional relationship in the length direction, or only the proportional relationship in the width direction, or both the proportional relationship in the length direction and the proportional relationship in the width direction may 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 disposed in direct correspondence; two sub-through holes 414 in adjacent columns are disposed in direct correspondence.

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

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

[0126] There are three limiting conditions in the same column: the vertical distance of the sub-through hole 414 from the edge of the suspension member 41, the length of each sub-through hole 414, and the spacing between two sub-through holes 414 in adjacent rows. This embodiment can make the vertical distance of the sub-through hole 414 from the edge of the suspension member 41, the length of each sub-through hole 414, and the spacing between two sub-through holes 414 in adjacent rows equal, that is, L1=L2=L3, thereby improving the uniformity of the strength of the suspension member 41. This avoids severe strength attenuation at a certain position due to an excessively large dimension of a certain limiting condition, which would subsequently cause plastic bending deformation at that location.

[0127] Similarly, three limiting conditions exist within the same row: the vertical distance between the edge sub-through hole 414 and the edge of the suspension member 41, the spacing between two sub-through holes 414 in adjacent columns, and the width of each sub-through hole 414. This embodiment ensures that the vertical distance between the edge sub-through hole 414 and the edge of the suspension member 41, and the spacing between two sub-through holes 414 in adjacent columns are equal, i.e., D1 = D3. This also improves the uniformity of the strength of the suspension member 41. It avoids severe strength attenuation at a certain location due to an excessively large dimension of a certain limiting condition, which could subsequently lead to plastic bending deformation at that location.

[0128] It is worth noting that this embodiment may only satisfy the limiting conditions in the sub-through holes 414 in the same column, or only satisfy the limiting conditions in the sub-through holes 414 in the same row, or simultaneously satisfy 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 3mm-6mm, and the width of each sub-through hole 414 is 0.3mm-1mm.

[0130] For each sub-via 414, the length of each sub-via 414 (e.g.) Figure 7As shown in L2, the length of each sub-hole 414 is 3mm-6mm. If the length of each sub-hole 414 is too small, for example, less than 3mm, the vertical extension dimension of each sub-hole 414 will be too small, failing to solve the stress concentration problem, and the flexibility of the suspension 41 will also decrease, weakening the vibration damping effect. If the length of each sub-hole 414 is too large, for example, greater than 6mm, the length of each through-hole 414 will be too long, reducing the strength of the suspension 41. In summary, by making the length of each sub-hole 414 3mm-6mm, this embodiment enables the suspension 41 to not only solve the stress concentration problem but also have excellent vibration damping effect and structural strength.

[0131] Furthermore, the width of each sub-hole 414 (e.g.) Figure 7 As shown in D2, the width of each sub-through hole 414 is 0.3mm-1mm. If the width of each sub-through hole 414 is too small, for example, less than 0.3mm, 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 mm, the distance the through hole 410 extends in the width direction will be too long, further reducing the strength of the suspension member 41. Furthermore, actual testing shows that when the through hole 410 extends the same distance in both the length and width directions, the reduction in strength is more pronounced in the width direction. In summary, this embodiment, by making the width of each sub-through hole 414 0.3mm-1mm, not only reduces the manufacturing difficulty of the through hole 410 but also gives the suspension member 41 excellent strength.

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

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

[0134] In this embodiment, each sub-through hole 414 is manufactured by a stamping process, and each sub-through hole 414 is a racetrack-shaped hole. A racetrack-shaped hole refers to a through hole 410 whose overall shape is similar to a rectangle, but whose two sides in the length direction are not straight lines, but rather arcs. In this embodiment, the sub-through holes 414 are manufactured by a stamping process; therefore, designing the sub-through holes 414 as racetrack-shaped holes ensures stamping stability and quality, and avoids stamping defects caused by right-angle holes.

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

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

[0137] The above embodiments have described the through hole 410 from various perspectives. This embodiment provides a detailed structure of a specific suspension member 41. The through hole 410 in the suspension member 41 consists of four sub-through holes 411 in two rows and two columns. Each sub-through hole 414 extends along the length of the suspension member 41. The two sub-through holes 414 in adjacent rows and adjacent columns are arranged in direct correspondence. Each sub-through hole is made 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 (e.g. Figure 7 (As shown in L) 20.9mm, the vertical distance from the sub-through hole 414 to the edge of the suspension member 41 (as shown in L) Figure 7 As shown in L1), the length of the sub-hole 414 (as shown in L1) Figure 7 As shown in L2), and the distance between two sub-through holes 414 in adjacent rows (as shown in L2). Figure 7 (As shown in L3) are all 4mm. Along the width direction, the width of the suspension member 41 (as shown in L3) is... Figure 7 The distance from the sub-hole 414 to the edge of the suspension member 41 (as shown in D) is 8mm. Figure 7 As shown in D1), and the distance between two sub-holes 414 in adjacent columns (as shown in D1). Figure 7 As shown in D3, all are 2.4mm, and the width of the sub-hole 414 (as shown in D3) is 2.4mm. Figure 7 The value (as shown in D2) is 0.4 mm.

[0139] With the above configuration, the suspension component 41 can not only absorb internal stress and avoid stress concentration, but also give the suspension component 41 excellent strength and flexibility, excellent comprehensive performance, and prevent plastic deformation or even breakage from falling.

[0140] The above text details the parameters of the through hole 410 in the suspension component 41 and the unexpected technical effects it brings. Next, we will further introduce other structural features in the motor 1.

[0141] Please refer to this as well. Figure 2 , Figures 4-5 ,as well as Figures 8-9 , Figure 8 for Figure 4 A partially enlarged view of the motor shown. Figure 9 for Figure 1 The diagram shows a partial enlarged view of the motor. In this embodiment, the drive assembly 20 includes a base 21 and a drive member 22, with the drive member 22 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 located 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 fixes them in place. 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 located on the frame 10, and the third clamping member 44 is located on 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 therethrough. The frame 10 is made of a different material than the suspension member 41.

[0143] The drive assembly 20 consists of a base 21 and a drive element 22. The base 21 is used to mount and support the drive assembly 20, the motion module 30a, and even other components. The drive element 22 is used to generate an electromagnetic effect and can be connected to the base 21 in various ways, such as being fixedly connected to the base 21. Optionally, there can be two drive elements 22, arranged along the direction of movement. Further optionally, each drive element 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, and the winding 222 includes, but is not limited to, copper wire, which can be a flat wire.

[0144] In addition to the suspension member 41, the suspension assembly 40 may also 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 secure and fix it. One end of the suspension member 41 (lower end) can be close to the base 21, and the other end (upper end) of the suspension member 41 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 positioned on opposite sides of that end to clamp the suspension member 41 for better fixation. Furthermore, 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, thereby fixing 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. Then, the fixed first clamp 42, one end of the suspension member 41, and the second clamp 43 are connected to one side of the base 21 in various ways, such as by welding 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 they are welded, the stability of the weld is poor. Optionally, the frame 10 is made of zinc alloy, and the suspension member 41 and various clamping members are made of stainless steel. Therefore, in this embodiment, the other end of the suspension member 41 is located on the frame 10, and only the third clamping member 44 is located on the other end of the suspension member 41 away from the frame 10. 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, thereby fixing the third clamping member 44, the other end of the suspension member 41, the frame 10, and the second fixing member 46 together to achieve a stable connection.

[0146] Furthermore, in this embodiment, only one clamping member is used 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. This reduces the overall thickness at the other end of the suspension member, thereby leaving sufficient distance between it and the motion module 30a to prevent them from interfering with each other during movement.

[0147] Optionally, the frame 10 has an inner sidewall, and the inner sidewall of the frame 10 and the third clamping member 44 are located on opposite sides of the other end of the suspension member 41. Understandably, the inner sidewall 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 fix the suspension member 41 has advantages such as simple installation and firm connection.

[0149] Please refer to this as well. Figure 8 , Figures 10-11 , Figure 10 This is a partial three-dimensional structural diagram of the base and suspension assembly in one embodiment of this application. Figure 11 for Figure 10 The diagram shows a partial cross-sectional view of the base and suspension assembly in action. 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 disposed on opposite sides of the first through portion 450. The first through portion 450 passes 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 disposed on the side of the first clamping member 42 away from the suspension member 41, and the second fixing portion 452 is disposed on the side of the second clamping member 43 away from the suspension member 41. 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 a first connecting hole 47.

[0150] The outer side wall of the base 21 is provided with a first protrusion 212. The first protrusion 212 is located in the first connecting hole 47 and a second clamping member 43 is welded thereon. There is a gap between the first fixing part 451 and the base 21. The cross-sections of the first connecting hole 47 and the first protrusion 212 are non-circular.

[0151] The first fixing member 45 may consist of a first through portion 450 in the middle, and first fixing portions 451 and second fixing portions 452 at both ends. The first through portion 450 is used to pass through the first clamping member 42, one end of the hanging member 41, and the second clamping member 43. The first fixing portions 451 and second fixing portions 452 protrude from the first clamping member 42 and the second clamping member 43, respectively. For example, the first fixing portion 451 is located on the side of the first clamping member 42 away from the hanging member 41, and the second fixing portion 452 is located on the side of the second clamping member 43 away from the hanging member 41. Optionally, the first fixing member 45 is dumbbell-shaped, that is, the outer diameter of the first fixing portion 451 and the outer diameter of the second fixing portion 452 are larger than the outer diameter of the first through portion 450, which can improve the connection effect. Furthermore, the first fixing portion 451 is closer to the base 21, and the second fixing portion 452 is farther away from the base 21, that is, the first fixing portion 451 is located inward, and the second fixing portion 452 is located outward. Additionally, a first connecting hole 47 can be provided at one end of the first clamping member 42, the hanging member 41, and the second clamping member 43.

[0152] A first protrusion 212 may be provided on the outer wall of the base 21. In other words, the first protrusion 212 is thickened so that it is far away from the outer wall of the base 21. Thus, when the first protrusion 212 is provided in the first connecting hole 47 and the second clamping member 43 is welded, a certain distance can be maintained between the first fixing part 451, which is closer to the base 21, and the outer wall of the base 21, so as to avoid interference between the first fixing part 451 and the base 21.

[0153] It is worth noting that by welding the second clamping member 43 to the first protrusion 212, the suspension assembly 40 can be fixedly connected to the base 21. Furthermore, the second clamping member 43, located on the outer side, is also convenient for welding to the first protrusion 212, reducing welding difficulty. Of course, in other embodiments, the first clamping member 42, located more internally, can also be welded to the first protrusion 212, thereby further improving the connection performance. However, the suspension member 41 is not welded to the first protrusion 212. The purpose of the clamping member in this embodiment is to transfer the welding area, avoiding welding of the suspension member 41 and preventing thermal deformation of the suspension member 41 due to welding, which would affect stress and elasticity properties, thus impacting vibration damping performance.

[0154] Optionally, the first protrusion 212 can be directly disposed on the outer side wall of the base 21, or a fixing seat 211 can be first disposed on the outer side wall of the base 21, and then the first protrusion 212 can be disposed on the side of the fixing seat 211 away from the base 21. This way, the fixing seat 211 can be used to keep the first protrusion 212 away from the base 21, thereby ensuring that there is a certain distance between the first fixing part 451 and the outer side wall of the base 21, and avoiding interference between the first fixing part 451 and the base 21.

[0155] Furthermore, in this embodiment, the cross-section of the first connecting hole 47 and the first protrusion 212 can be non-circular. Compared to a circular first connecting hole 47 and first protrusion 212, this embodiment can achieve positioning using only one set of first connecting holes 47 and first protrusion 212. Optionally, the cross-section of the first connecting hole 47 and the first protrusion 212 can be rectangular. A rectangular plane is more conducive to dimensional inspection and more conducive to CNC machining when precise positioning is required.

[0156] Please refer to this as well. Figure 2 and Figure 8In this embodiment, the drive assembly 20 includes a base 21 and a drive member 22, with the drive member 22 connected to the base 21. The motion module 30a includes a motion component 30 and a support assembly 50. One end of the support assembly 50 is connected to the base 21, and the other end is connected to the motion assembly 30. The motion component 30 is located on the side of the drive member 22 facing away from the base 21. The support assembly 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 located 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 fixes them. 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 component 51 is provided with a second connecting hole 510. The motion component 30 is provided with a second protrusion 300. The second protrusion 300 is located in the second connecting hole 510 and welded to the other end of the support component 51. The cross-sections of the second connecting hole 510 and the second protrusion 300 are non-circular.

[0158] The base 21 and the drive component 22 have been described in detail above, and will not be repeated here 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 of the support component 50 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 located on the side of the drive component 22 away from the base 21, that is, the motion component 30 is located on the upper side of the drive component 22.

[0159] The motion component 30 and the drive component 22 cooperate to perform reciprocating movement. For example, the motion component 30 includes a motion base 31 and a permanent magnet 32. The permanent magnet 32 ​​is fixedly disposed on the side of the motion base 31 adjacent to the drive component 22, that is, the permanent magnet 32 ​​is fixed on the lower side of the motion base 31. When the drive component 22 is working, it can periodically change its magnetic poles. Therefore, the drive component 22 and the permanent magnet 32 ​​with fixed magnetic poles can cooperate to achieve reciprocating movement. The drive component 22 drives the base 21 to reciprocate, and the permanent magnet 32 ​​drives the motion base 31 to reciprocate. During the movement, the motion component 30 transmits vibration to the base 21 through the support component 50. The support component 50 itself also has a certain degree of elasticity and toughness, so it can also reduce vibration to a certain extent.

[0160] Optionally, there is a gap between the motion component 30 and the drive component 22 to reduce contact and avoid mutual friction between the two, thereby reducing the movement effect.

[0161] Optionally, the number of support components 50 can be one or more. This embodiment only illustrates two support components 50, and the two support components 50 are connected to the opposite ends of the motion component 30.

[0162] The support assembly 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 assembly 30, providing support. There can be one or more support members 51; this embodiment only illustrates two support members 51. The various clamping members in the support assembly 50 are mainly used to clamp the support member 51 to secure and fix it. One end of the support member 51 (lower end) can be close to the base 21, and the other end (upper end) can be close to the motion assembly 30. For one end of the support member 51, the fourth clamping member 52 and the fifth clamping member 53 can be located on opposite sides of one end of the support member 51, using the two clamping members to clamp the support member 51 for better fixation. Furthermore, 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, thereby fixing the fourth clamping member 52, one end of the support member 51, and the fifth clamping member 53 together with the third fixing member 54. Then, 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 can 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 component being provided at the other end of the support member 51. Optionally, the preset distance is 2.5mm-3mm. The other end of the support member 51 is provided with a second connecting hole 510, and the motion component 30 is provided with a second protrusion 300. The second protrusion 300 can be provided in the second connecting hole 510 and 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-section of the second connecting hole 510 and the second protrusion 300 can be non-circular. Compared with a circular second connecting hole 510 and second protrusion 300, this embodiment can achieve positioning using only one set of second connecting holes 510 and second protrusion 300. Optionally, the cross-section of the second connecting hole 510 and the second protrusion 300 is rectangular. The rectangular plane is more conducive to dimensional inspection and more conducive to CNC machining when precise positioning is required.

[0164] Optionally, when there are multiple support members 51, the support assembly 50 may further include a fourth fixing member 55. The fourth fixing member 55 can pass through the other end of multiple support members 51 and fix them together, thereby fixing the other ends of multiple support members 51 together and preventing the other ends of multiple support members 51 from loosening and separating. Furthermore, when the support assembly 50 includes multiple support members 51, only the outermost support member 51, that is, the support member 51 farthest from the drive member 22, is welded to the second protrusion 300, reducing the welding difficulty.

[0165] It is worth noting that in other embodiments, the motion module 30a may include a motion component 30 and a suspension component 40. One end of the suspension component 40 is connected to the base 21, and the other end is connected to the motion component 30. The motion component 30 is located on the side of the drive member 22 away from the base 21. In other words, in this embodiment, the motion component 30 is not connected and supported by the support component 50. The motion component 30 can also be connected by the suspension component 40 provided in the above embodiments. For example, the suspension component 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 described above. For the specific structure of the suspension member 41 and the suspension component 40, please refer to the above embodiments. This embodiment will not be described again here.

[0166] Please refer to this as well. Figure 10 and Figure 12 , Figure 12 This is a partial cross-sectional schematic diagram of the base and support assembly in one embodiment of this 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 support 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 consists of a bottom wall 213, on which a positioning hole 2130 can be formed. The fourth clamping member 52, one end of the support member 51, and the fifth clamping member 53 can abut against the bottom wall 213. The fourth clamping member 52, one end of the support member 51, and the lower end of the fifth clamping member 53 can extend into the positioning hole 2130. 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 support assembly 50 to the base 21, reducing the difficulty of fixing and improving the fixing effect. The positioning hole 2130 can also improve the positioning accuracy of the fourth clamping member 52, one end of the support 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 stress and elastic properties, 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 near the drive member 22, i.e., the top of the inner wall of the positioning hole 2130, to provide guidance when the fourth clamping member 52, one end of the support member 51, and the fifth clamping member 53 are located on the base 21.

[0170] Please refer to this as well. Figure 10 and Figure 13 , Figure 13 This is a partial cross-sectional schematic diagram of the base and support assembly in another embodiment of this application. In this embodiment, the third fixing member 54 includes a second through portion 540, and a third fixing portion 541 and a fourth fixing portion 542 disposed on opposite sides of the second through portion 540. The second through portion 540 passes through 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 the side of the fourth clamping member 52 away from the support member 51, and the fourth fixing portion 542 is disposed on the 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. The side wall 214 is provided with a relief groove 215 and a receiving groove 216. The third fixing part 541 and the fourth fixing part 542 are both provided in the relief groove 215. The fourth clamping member 52, one end of the support member 51, and the fifth clamping member 53 are provided in the receiving groove 216. 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 third fixing portions 541 and fourth fixing portions 542 at both ends. The second through portion 540 passes through the fourth clamping member 52, one end of the support member 51, and the fifth clamping member 53. The third fixing portions 541 and fourth fixing portions 542 protrude from the fourth clamping member 52 and the fifth clamping member 53, respectively. For example, the third fixing portion 541 is located on the side of the fourth clamping member 52 away from the support member 51, and the fourth fixing portion 542 is located on the 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 diameter of the third fixing portion 541 and the outer diameter of 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 part 541 and the fourth fixing part 542 protrude from the fourth clamping member 52 and the fifth clamping member 53, the basic embodiment can provide a clearance 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 part 541 and the fourth fixing part 542 can be placed in the clearance groove 215, thereby using the clearance groove 215 to avoid the third fixing part 541 and the fourth fixing part 542, and avoid interference between the third fixing member 54 and the base 21.

[0173] Optionally, a first guide slope 2141 may be provided on the side of the side wall 214 away from the bottom wall 213, which provides a guiding function when the fourth clamping member 52, one end of the support member 51, and the fifth clamping member 53 are located 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 disposed in the receiving groove 216, and the fourth clamping member 52 and the fifth clamping member 53 can be welded to the side wall 214, while one end of the support member 51 is not welded to the side wall 214. This can prevent the support member 51 from being deformed by heat due to welding, thereby affecting the stress and elastic properties, and thus affecting the vibration reduction performance.

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

[0176] A first observation hole 101 can also be provided on the frame 10. The first observation hole 101 can expose at least part of the support component 50, which not only reduces the weight of the frame 10, but also allows the user to observe the movement process of the support component 50 through the first observation hole 101, so as to realize the visualization of the movement process and enhance the sense of technology. In addition, the first observation hole 101 can also be used to observe whether the support component 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, meaning that the size of the first observation hole 101 will not be too large. The suspension assembly 40 is offset from the first observation hole 101, meaning that the first observation hole 101 does not expose the suspension assembly 40. This firstly exposes the support assembly 50, which is sufficient for observation, and secondly avoids reducing the strength of the frame 10 by making the first observation hole 101 too large.

[0178] Optionally, the frame 10 is also provided with a second observation hole 102, which is used to expose part of the drive component 22, so that the user can also observe the reciprocating movement of the drive component 22.

[0179] Alternatively, there may be two first observation holes 101, which are located on opposite sides of the second observation hole 102. One first observation hole 101 is used to expose one support component 50, and the other first observation hole 101 is used to expose another support component 50.

[0180] Please refer to this as well. Figures 14-15 , Figure 14 This is a three-dimensional structural diagram of a hair trimmer according to one embodiment of this application. Figure 15 for Figure 14 The exploded view of the hair trimmer shown is shown. This embodiment provides a hair trimmer 5, which includes a housing 2, a transmission assembly 3, a blade head 4, and a motor 1 as provided in the above embodiments of this application. The motor 1 is disposed inside the housing 2, the transmission assembly 3 is connected to the motion module 30a of the motor 1, and the blade head 4 is connected to the transmission assembly 3.

[0181] The hair trimmer 5 is mainly used to trim various types of hair on the human body, including but not limited to beards, hair, and armpit hair. In this embodiment, only beards are used for illustrative purposes. In this case, 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 blade head 4, and a motor 1. The housing 2 is mainly used to install the other parts of the hair trimmer 5. For example, the housing 2 includes a main body shell and an end cap. The motor 1 is located inside the main body shell. The main body shell has an opening. The end cap is located at the opening and connected to the main body shell. The top of the frame 10 in the motor 1 is connected to the end cap to transmit vibration upwards and reduce the vibration felt by the user when holding it.

[0183] The transmission component 3 is connected to the motion module 30a. When the motion module 30a reciprocates, it can synchronously drive the transmission component 3 to reciprocate. The blade head 4 is connected to the transmission component 3. When the transmission component 3 reciprocates, it can synchronously drive the blade head 4 to reciprocate, thereby achieving the purpose of trimming hair.

[0184] The hair trimmer 5 of this embodiment, by employing the motor 1 provided in the above embodiment, firstly, 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 degree of elasticity and flexibility, it can absorb some of the vibration generated when the drive assembly 20 and the motion module 30a reciprocate, thus improving the vibration reduction effect. Secondly, compared to a single piece of suspension 41 without holes, opening through holes 410 in the suspension 41 can reduce the internal stress of the suspension 41 and reduce the stress concentration generated during the assembly process, thereby reducing the local deformation of the suspension 41. Thirdly, the through holes 410 can extend vertically along the direction from the first side 412 to the second side 413 of the suspension 41. Compared to through holes extending laterally, this can increase the strength of the suspension 41, prevent the suspension 41 from bending and deforming due to the entire machine being dropped, and improve its drop resistance. Furthermore, the through hole 410 is spaced from both the first side 412 and the second side 413, ensuring 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 to the through hole 410 penetrating not only the opposite two surfaces in the thickness direction of the suspension member 41, but also one surface in the length direction of the suspension member 41, this application can further improve the strength of the suspension member 41 and prevent bending deformation during a fall.

[0185] In summary, this embodiment can reduce vibration by adding a suspension assembly 40. By opening a through hole 410 with a specific structure on the suspension member 41 in the suspension assembly 40, stress concentration can be reduced, strength can be increased, drop deformation can be avoided, and drop resistance can be improved.
