[0001] The invention relates to a transmission part, and more specifically to a swing mechanism with vibration reduction function and a shaver, which are mainly used in reciprocating shavers with multiple blade heads. Background Art

[0002] Existing multi-blade reciprocating shavers basically use a swing mechanism to convert the rotational motion of a motor into a reciprocating motion to drive a blade assembly mounted on the swing mechanism to shave and trim the beard.

[0003] The applicant applied for a razor and a razor head device thereof on May 10, 2012, with the announcement number: CN102642213B. In the patent document, a first swing frame 13 and a second swing frame 14 are specifically disclosed, and are linked and connected by a rotating member 15. The first swing frame 13 and the second swing frame 14 are fixed to the housing 11 by elastic parts 162 and connecting parts 161 arranged at two ends respectively; and in order to facilitate the horizontal reciprocating swing of the first swing frame 13 and the second swing frame 14, a swing frame 07 is arranged on the first swing frame 13 and a transmission head 06 with an eccentric shaft is placed in the swing frame 07. When the motor rotates, the eccentric shaft on the transmission head 06 will repeatedly push the side walls on both sides of the swing frame 07 to drive the first swing frame 13 to swing back and forth horizontally, and the second swing frame 14 will synchronously drive the second swing frame 14 to swing back and forth horizontally in the opposite direction to the first swing frame 13 under the action of the rotating member 15 to improve the working stability of the swing mechanism and reduce noise.

[0004] Although the above structure can improve the working stability of the swing mechanism and reduce the working noise, in actual use, the first swing frame 13 and the second swing frame 14 are linked and connected by a rotating member 15 arranged in the middle, and when the eccentric shaft of the transmission head pushes the side walls of the swing frame 07 on both sides during rotation, it not only drives the first swing frame 13 to swing back and forth horizontally, but also applies a radial thrust to the side walls of the swing frame 07 on both sides in the rotation direction of the transmission head 06, so that the two ends of the first swing frame 13 form a radial torsional force during the reciprocating swing process, which greatly improves the vibration of the first swing frame 13 and reduces the comfort of the shaver when in use.

[0025] The embodiments of the present invention are further described below in conjunction with the accompanying drawings:

[0026] like Figure 1-7 As shown, the present invention is a swing mechanism with a vibration reduction function, including an active swing member 1 and a passive swing member 2 fixedly connected to a shell and synchronously linked, a swing frame 11 is provided on the active swing member 1, and the swing frame 11 is linked with a driving mechanism; the driving mechanism mainly consists of a motor installed in the body and a transmission wheel with an eccentric shaft, the transmission wheel is fixed to the motor output shaft, and the eccentric shaft is inserted into the swing frame 11 arranged on the active swing member 1, when the motor drives the transmission wheel to rotate, the eccentric shaft will repeatedly rotate and hit the side walls of the swing frame 11 to make the active swing frame 11 swing back and forth, when the eccentric shaft rotates and hits the side walls of the swing frame 11, not only a lateral thrust is applied to the side walls of the swing frame 11 to make the active swing member 1 swing back and forth, but also a radial thrust is applied to the side walls of the swing frame 11 in the rotation direction, so that the two ends of the active swing member 1 are repeatedly twisted in sequence, which greatly increases the working vibration intensity of the shaver and reduces the comfort of using the shaver. In order to improve the torsional resistance of the active swing member 1 and minimize the torsional amplitude at both ends of the active swing member 1 during the horizontal reciprocating swing, a first spring piece 12 is provided on both sides of the active swing member 1, and a second spring piece 22 is provided on both sides of the passive swing member 2. The width of the first spring piece 12 is W 1 Greater than the width W of the second elastic piece 22 2 . By respectively arranging the first spring piece portion 12 and the second spring piece portion 22 on both sides of the active pendulum 1 and the passive pendulum 2, when the active pendulum 1 and the passive pendulum 2 are fixed in the shell and the driving mechanism drives the active pendulum 1 to swing back and forth horizontally, it is possible to reduce the resistance of the active pendulum 1 and the passive pendulum 2 during the horizontal reciprocating swing, thereby ensuring the horizontal swing performance of the active pendulum 1 and the passive pendulum 2 and reducing the working current, thereby extending the battery life. At the same time, it is also possible to facilitate the rapid resetting of the active pendulum 1 and the passive pendulum 2. Secondly, since the passive pendulum 2 is subordinate to the active pendulum 1 and is synchronously linked with the active pendulum 1, it itself is not connected to the driving mechanism. Therefore, no twisting occurs at both ends of the passive pendulum 2. Based on this, in the structural design, the width W of the passive pendulum 2 and the second spring piece portions 22 on both sides thereof can be reduced. 2 The limited installation space is saved to increase the width W of the first spring piece portion 12 on both sides of the active pendulum 11 , so that the width W of the first elastic sheet portion 12 1 Greater than the width W of the second elastic piece 22 2 Since the active swing element 1 is connected to the first spring sheet portions 12 on both sides and fixed to the housing, the width W of the first spring sheet portion 12 1 When the active swing member 1 is increased, the force-bearing area of ​​the joint between the active swing member 1 and the first elastic sheet 12 is also increased accordingly, and its anti-torsion force is also increased accordingly. When the transmission wheel of the driving mechanism rotates to make the eccentric shaft hit the side walls on both sides of the swing frame 11, although the radial torsion at both ends of the active swing member 1 cannot be completely avoided, the radial torsion amplitude at both ends of the active swing member 1 can be reduced to the greatest extent, slowing down or reducing the vibration intensity of the active swing member 1 when swinging left and right, thereby improving the comfort of the shaver.

[0027] Since there are many styles of razors using a swing mechanism, which are mainly distinguished by the number of blade heads, such as a three-blade razor, a four-blade razor, or even a razor with more blade heads, in order to improve the versatility of the swing mechanism, reduce the radial torsion amplitude of the active swing member 1 when the swing mechanism is applied to razors with different numbers of blade heads, reduce the vibration intensity of the razor when it is working, and reduce the vibration feeling of the razor, the width W of the first spring portion 12 is 1 Width W 总 The relationship is: W 1 =W 总 ×(0.2~0.5). Affected by other factors such as the thickness of the cutter head shell, the cutter head width W 总 It is not equal to the width of the cutter head housing that can be installed with the swing mechanism. The actual width of the cutter head housing that can be installed with the swing mechanism is greater than the cutter head width W. 总 To ensure that the swing mechanism can achieve the best effect when used in shavers with different numbers of blades, the width W of the first spring pieces 12 at both ends of the active swing element 1 is 1 Width W of the blade 总 Of course, during the production process, it can also be adjusted according to the actual situation of the internal space of the cutter head, and this embodiment does not make further restrictions.

[0028] Since the passive swing member 2 and the active swing member 1 are synchronously linked, the passive swing member 2 is not directly connected to the driving mechanism, so the passive swing member 2 does not undergo radial torsion during the swinging process; and in order to increase the torsion resistance of the active swing member 1, the width W of the first elastic sheet portion 12 is 1 The width W of the second elastic sheet portion 22 2 The relationship is: W 1 =W 2×(1.2~2). Since the passive swing element 2 is subordinate to the active swing element 1, no radial torsion will occur during its horizontal swinging, thus reducing the width W of the passive swing element 2 and the second elastic sheet portions 22 at both ends. 2 The limited installation space in the cutter head housing is used to increase the width W of the first spring sheet portion 12 at both ends of the active swing element 1. 1 , so that the width W of the first elastic sheet portion 12 1 is the width W of the second elastic piece 22 2 In actual production, the width ratio between the first elastic sheet portion 12 and the second elastic sheet portion 22 can be determined according to the width W of the cutter head. 总 Make appropriate adjustments, for example, when the blade width W 总 When the width W of the blade head is greater than 30 mm, the width ratio between the first elastic sheet portion 12 and the second elastic sheet portion 22 can be appropriately increased, such as 1.8 times or 2 times. 总 When the width of the first elastic sheet portion 12 is less than 30 mm, the width ratio between the first elastic sheet portion 12 and the second elastic sheet portion 22 can be set to 1.6 times, 1.5 times or 1.4 times, etc. The specific width ratio can be determined according to actual conditions and is not further limited in this embodiment.

[0029] In order to reduce the vibration intensity of the active swing member 1 during the horizontal reciprocating swing to the greatest extent, the width W of the first elastic sheet portion 12 is 1 ≥5mm. Theoretically, the width W of the first spring portion 12 at both ends of the active swing element 1 is 1 The larger the size, the stronger the torsional resistance. Limited by the installation space in the cutter head housing, the width W of the first spring pieces 12 at both ends of the active swing element 1 is 1 In actual production and processing, the width W of the first spring portion 12 is not less than 5 mm. 1 The size is first based on the blade width W 总 (Installation width in the cutter head housing) is used as the basis to determine the first spring portion 12 and the cutter head width W 总 and then determine the width ratio between the first spring portion 12 and the second spring portion 22 based on this; after determining the above two technical indicators, the actual width size of the first spring portion 12 and the second spring portion 22 can be determined.

[0030] In order to prevent the stress at the joint between the first spring piece 12 and the second spring piece 22 and the corresponding active swing member 1 and passive swing member 2 from being too concentrated, resulting in the first spring piece 12 and the second spring piece 22 being broken, the active swing member 1 has a width W 3 The width W of the first elastic sheet portion 12 1 And the width W of passive element 2 4 The width W of the second elastic sheet portion 22 2 The width ratio of the active pendulum 1 is 1:1.3 and the width W of passive element 2 4 are respectively set to be equal to the width W of the first elastic sheet portion 12 1 and the width W of the second elastic piece 22 2 Similarly, this can prevent the width of the first spring piece portion 12 and the second spring piece portion 22 from being greater than the width of the corresponding active swing member 1 and the passive swing member 2, so that the stress is concentrated on the part of the first spring piece portion 12 or the second spring piece portion 22 that exceeds the active swing member 1 or the passive swing member 2, preventing the first spring piece portion 12 or the second spring piece portion 22 from breaking and extending the service life of the swing mechanism.

[0031] To facilitate the installation and fixation of the active and passive ornamental members 1 and 2, the first spring piece portion 12 and the second spring piece portion 22 on both sides of the active and passive ornamental members 1 and 2 are both in the shape of thin sheets. The first spring piece portion 12 and the second spring piece portion 22 are set to be in the shape of thin sheets. During the horizontal swinging of the active and passive ornamental members 1 and 2, the thin sheet-shaped first spring piece portion 12 and the second spring piece portion 22 have less resistance, which can effectively reduce the working current of the shaver motor and extend the working time of the battery. The lower ends of the first spring pieces 12 are respectively connected to the bottoms of the two sides of the active pendulum 1 and the passive pendulum 2 to form U-shaped buffer grooves 7 on both sides of the active pendulum 1 and the passive pendulum 2. The width of the U-shaped buffer grooves 7 is greater than the unilateral swing stroke of the active pendulum 1 and the passive pendulum 2. The first spring piece 12 and the second spring piece 22 are respectively connected to the corresponding active pendulum 1 and the passive pendulum 2 to form U-shaped buffer grooves 7 on both sides. When the active pendulum 1 and the passive pendulum 2 are driven by the driving mechanism to swing back and forth horizontally, the U-shaped buffer grooves 7 give up the swing space of the active pendulum 1 and the passive pendulum 2, reduce the swing resistance, reduce the working current of the shaver motor, and extend the working time of the battery. A first fixing plate 13 is provided at the upper end of the first spring piece 12, and a second fixing plate 23 is provided at the upper end of the second spring piece 22. The first fixing plate 13 and the second fixing plate 23 are fixed to the shell in a limited connection. By adding corresponding first fixing plates 13 and second fixing plates 23 to the upper ends of the first spring sheet parts 12 and the second spring sheet parts 22, the first fixing plates 13 and the second fixing plates 23 can be combined together or fixed to the shell separately during assembly, thereby ensuring the installation firmness of the active pendulum 1 and the passive pendulum 2.

[0032] To facilitate the rapid assembly and mounting of the active rocker component 1 and the passive rocker component 2, at least one mounting through hole 131 and at least one limiting block 132 are respectively provided on the first fixing plate 13 at the top of the first elastic sheet portion 12 on both sides of the active rocker component 1; at least one threaded seat 231 with a threaded hole and a limiting hole 232 are provided on the second fixing plate 23 at the top of the second elastic sheet portion 22 on both sides of the passive rocker component 2, and the two ends of the threaded seat 231 are respectively placed outside the upper and lower end surfaces of the second fixing plate 23, the upper end of the threaded seat 231 passes through the mounting through hole 131 and the limiting block 132 is inserted into the limiting hole 232 so that the first fixing plate 13 is superimposed on the second fixing plate 23 and the active rocker component 1 and the passive rocker component 2 are fixed to the shell by screws and threaded connections with the threaded holes. A mounting through hole 131 is provided on the first fixing plate 13, and a threaded seat 231 is provided on the second fixing plate 23. During assembly, the threaded seat 231 is inserted into the mounting through hole 131 so that the first fixing plate 13 and the second fixing plate 23 are stacked together, and then the threaded seat 231 is fixed to the housing by screws, so that the active pendulum 1 and the passive pendulum 2 are fixed in the housing, ensuring the installation firmness of the active pendulum 1 and the passive pendulum 2. During actual assembly, two mounting through holes 131 are provided on the first fixing plate 13, and two threaded seats 231 are provided on the second fixing plate 23, so as to maximize the connection firmness between the first fixing plate 13 and the second fixing plate 23 and the housing. Since the passive pendulum 2 is subordinate to the active pendulum 1 and is synchronously linked with the active pendulum 1, in order to prevent dislocation or shaking between the active pendulum 1 and the passive pendulum 2, affecting the swing performance of the active pendulum 1 and the passive pendulum 2 and increasing the vibration intensity, a circular limit block 132 and a square limit block 132 are respectively provided on the first elastic piece part 12 at both ends of the active pendulum 1, and matching limit holes 232 are provided at corresponding positions on the second fixed plate 23 at both ends of the passive pendulum 2. The circular limit block 132 and the square limit block 132 are respectively inserted into the corresponding limit holes 232, which can not only effectively ensure the parallelism of the active pendulum 1 and the passive pendulum 2, prevent dislocation from affecting the swing performance, and reduce the vibration intensity of the swing mechanism; at the same time, it can also effectively prevent shaking or displacement between the active pendulum 1 and the passive pendulum 2, and improve the working stability of the active pendulum 1 and the passive pendulum 2.

[0033] In order to facilitate the reverse movement between the active pendulum 1 and the passive pendulum 2 during the horizontal reciprocating swing process to reduce the vibration intensity of the swing mechanism, at least two groups of linkage parts 3 are provided between the active pendulum 1 and the passive pendulum 2 to enable the active pendulum 1 and the passive pendulum 2 to move in the opposite direction. At least two groups of linkage parts 3 are provided on the active pendulum 1 and the passive pendulum 2. In the actual production and assembly process, two groups of linkage parts 3 are provided, and the two groups of linkage parts 3 are respectively installed at the two ends of the active pendulum 1 and the passive pendulum 2 near the edge. Compared with the traditional swing mechanism using one group of linkage parts 3, two groups of linkage parts 3 are provided to enable the passive pendulum 2 and the active pendulum 1 to synchronously run in the opposite direction, which can not only greatly offset the impact force of the unidirectional motion inertia of the active pendulum 1 and the passive pendulum 2 and reduce the vibration intensity of the swing mechanism, but also effectively improve the parallelism of the reciprocating swing at both ends of the active pendulum 1 and the passive pendulum 2 to ensure the shaving efficiency of the razor.

[0034] In order to facilitate the active pendulum 1 and the passive pendulum 2 to form opposite movements during the reciprocating swing process to offset the impact force generated by their respective movement inertia, reduce the vibration intensity of the swing mechanism and ensure the parallelism during the swinging process, and improve the shaving efficiency, linkage grooves 4 are respectively provided at the edges of both sides of the upper end surfaces of the active pendulum 1 and the passive pendulum 2. The linkage member 3 includes a bridging plate 31, and a hinge hole 32 hinged to a hinge shaft arranged on the shell is provided at the center of the bridging plate 31. Linkage shafts 33 are symmetrically provided on both sides of the hinge hole 32 on the bridging plate 31. The outer diameter of the linkage shaft 33 matches the width of the linkage groove 4 and is respectively inserted into the linkage grooves 4 on the upper end surfaces of the active pendulum 1 and the passive pendulum 2 so that when the active pendulum 1 swings back and forth, the passive pendulum 2 swings back and forth in the opposite direction of the active pendulum 1. By arranging linkage grooves 4 near the edges at both ends of the active rocker 1 and the passive rocker 2, the assembly efficiency can be improved when assembling the linkage part 3; and the width of the linkage groove 4 is set to match the diameter of the linkage shaft 33. When the driving mechanism drives the active rocker 1 to swing back and forth left and right through the swing frame 11 arranged below the active rocker 1, the linkage shaft 33 inserted at the edge of the passive rocker 2 can only move in the opposite direction due to the limitation of the width of the linkage groove 4, so that the passive rocker 2 passively swings in the opposite direction of the active rocker 1 to offset the impact force generated by each in the inertia of movement; and a hinge hole 32 is arranged on the bridge plate 31, and during assembly, the hinge shaft arranged on the shell panel can be used for hinge connection, so as to ensure the working stability of the linkage part 3 during the reciprocating swing of the active rocker 1 and the passive rocker 2, and ensure the shaving efficiency of the razor.
