A hair clipper drive structure and a hair clipper

Abstract

The present invention provides a hair clipper drive structure and a hair clipper. The hair clipper drive structure includes a drive device, a drive sleeve, a swing wheel, a swing member, a first mounting plate, a resilient steel sheet, and a second mounting plate. During use, the drive device is activated to drive the drive shaft to drive the drive sleeve to rotate. The rotation of the drive sleeve drives the eccentric shaft to rotate synchronously. The rotation of the eccentric shaft drives the swing wheel to rotate within the cam drive groove and transmits power to the cam drive groove, enabling the swing member to swing left and right and driving the cutter head to perform a reciprocating motion. When the swing member swings, the first mounting plate swings synchronously and drives one end of the resilient steel sheet to swing. When the resilient steel sheet swings, a resilience force is generated due to its own inertia, and this force is transmitted to the swing member, and the swing member swings by means of the resilience force. The swing member swings by means of the resilience force of the resilient steel sheet, reducing the motor load, thereby improving the battery life, reducing the loss of the drive device, and further enhancing the service life of the hair clipper.

[0053] The following will describe this application in detail with reference to the drawings and in combination with embodiments. Embodiment 1

[0054] This embodiment provides a driving structure for a hair clipper, as Figures 1-3 shown, including: a driving device 6, a driving sleeve 5, a swing wheel 52, a swing member 1, a first mounting plate 2, an elastic steel sheet 3, and a second mounting plate 4; wherein, the driving device 6 has a driving shaft 61; one end of the driving sleeve 5 is fixedly sleeved on the driving shaft 61, and the other end has an eccentric shaft 51, the axis of the eccentric shaft 51 is parallel to but does not coincide with the axis of the driving shaft 61; the swing wheel 52 is mounted on the eccentric shaft 51; one end of the swing member 1 has a cam driving groove 11, and the other end is adapted to be connected to a cutter head; the swing wheel 52 can be mounted into the cam driving groove 11, and can drive the swing member 1 to swing left and right by driving the cam driving groove 11 under the drive of the driving device 6; the first mounting plate 2 is fixedly mounted at the bottom of the swing member 1; there are at least two elastic steel sheets 3, and one end of each is respectively mounted on both sides of the first mounting plate 2; the second mounting plate 4 is adapted to be fixedly mounted on the hair clipper, and the other ends of at least two of the elastic steel sheets 3 are respectively mounted on both sides of the second mounting plate 4; the swing of the swing member 1 drives the swing of the first mounting plate 2, and further drives one end of the elastic steel sheet 3 to swing relative to the other end; when the elastic steel sheet 3 rebounds, it can drive the swing member 1 to swing.

[0055] Before using the hair clipper drive structure of this embodiment, install the drive structure on the hair clipper and install the cutter head on the other end of the swing member 1. During use, the drive device 6 is started to drive the drive shaft 61 to drive the drive sleeve 5 to rotate. The rotation of the drive sleeve 5 drives the eccentric shaft 51 to rotate synchronously. The rotation of the eccentric shaft 51 drives the swing wheel 52 to rotate in the cam drive groove 11 and transmits the power to the cam drive groove 11, so that the swing member 1 can swing left and right and can drive the cutter head to reciprocate along a preset trajectory. While the swing member 1 is swinging, the first mounting plate 2 swings synchronously and drives one end of the elastic steel sheet 3 to swing relative to the other end. During the swinging process of the elastic steel sheet 3, a resilience force will be generated due to its own inertia. This force is transmitted to the first mounting plate 2 and then to the swing member 1. The swing member 1 can swing with the resilience force generated when the elastic steel sheet 3 swings. The hair clipper drive structure of this embodiment abandons the design of multiple drive components in the traditional drive structure and adopts a streamlined layout of drive components, making the overall structure simpler. Moreover, the swing member 1, the first mounting plate 2, and the second mounting plate 4 can all be integrally injection-molded, simplifying the production process and improving the production efficiency. In addition, the swing member 1 can swing with the resilience force generated when the elastic steel sheet 3 swings, reducing the motor load, thereby improving the battery life, reducing the loss of the drive device 6, and further increasing the service life of the hair clipper.

[0056] The thickness of the elastic steel sheet 3 is at least 0.06 mm. At least 10 pieces of the elastic steel sheet 3 are respectively installed on both sides of the first mounting plate 2 and the second mounting plate 4. After testing by the inventor, when at least 10 pieces of elastic steel sheets 3 are installed and the thickness is at least 0.06 mm, it can reach more than 200 h, which can meet the general requirements for the service life of the hair clipper.

[0057] In addition, it can also be designed that the thickness of the elastic steel sheet 3 is at least 0.09 mm, and at least 3 pieces of the elastic steel sheet 3 are respectively installed on both sides of the first mounting plate 2 and the second mounting plate 4. After testing by the inventor, when at least 3 pieces of elastic steel sheets 3 are installed and the thickness is at least 0.09 mm, it can also reach more than 200 h, thus meeting the general requirements for the service life of the hair clipper.

[0058] One end of the elastic steel sheet 3 is fixedly installed on the first mounting plate 2 through a first mounting structure; the first mounting structure includes a first connecting plate 21, a first riveting post 32, and a first connecting through hole 31; wherein, there are two first connecting plates 21, which are integrally formed on both sides of the first mounting plate 2 respectively; there are at least two first riveting posts 32, which are respectively formed on the outer side walls of the two first connecting plates 21; the first connecting through hole 31 is oppositely opened at one end of the elastic steel sheet 3 relative to the first riveting post 32; the first riveting post 32 is fixedly connected with the first connecting through hole 31 by means of press riveting, so as to fixedly install one end of the elastic steel sheet 3 on the first mounting plate 2; the other end of the elastic steel sheet 3 is fixedly installed on the second mounting plate 4 through a second mounting structure; the second mounting structure includes a second connecting plate 41, a second riveting post 34, and a second connecting through hole 33; wherein, there are two second connecting plates 41, which are integrally formed on both sides of the second mounting plate 4 respectively; there are at least two second riveting posts 34, which are respectively formed on the outer side walls of the two second connecting plates 41; the second connecting through hole 33 is oppositely opened at the other end of the elastic steel sheet 3 relative to the second riveting post 34; the second riveting post 34 is fixedly connected with the second connecting through hole 33 by means of press riveting, so as to fixedly install the other end of the elastic steel sheet 3 on the second mounting plate 4. The specific method of press riveting and fixing is that the riveting post is made of plastic material. During assembly, the riveting post is passed through the connecting through hole, and then the free end of the riveting post extending out of the connecting through hole is subjected to hot pressing operation by a hot pressing device. The high temperature makes the plastic riveting post soften by heating and be evenly flattened under pressure, and finally the elastic steel sheet 3 is fixedly installed.

[0059] Two first internal thread blind holes 12 are opened at the bottom of the swinging member 1, and two first mounting through holes 23 are opened on the first mounting plate 2 opposite to the first internal thread blind holes 12. A first mounting bolt passes through the first mounting through hole 23 and is screwed with the first internal thread blind hole 12 to fixedly install the first mounting plate 2 on the swinging member 1.

[0060] As Figure 3 shown, limiting plates 13 are respectively arranged on both sides of the two first internal thread blind holes 12 at the bottom of the swinging member 1, and the first mounting plate 2 is installed between the two limiting plates 13. The limiting plates 13 are used to limit the first mounting plate 2, so that the first mounting plate 2 is more stable during swinging and avoid falling off or shifting.

[0061] An annular mounting groove 53 is provided at a position of the eccentric shaft 51 close to the free end; further included is an elastic retaining ring 54, and the elastic retaining ring 54 can be fixedly installed in the annular mounting groove 53 for limiting the swinging wheel 52.

[0062] As Figure 2As shown, on both sides of the swing member 1, first reinforcing ribs 14 are formed at one end close to the cam drive groove 11, and a groove 15 is formed at the top. Second reinforcing ribs 16 are formed inside the groove 15. The first reinforcing ribs 14 are used to hold the outer wall of the cam drive groove 11 to prevent the cam drive groove 11 from being concave; the groove 15 is used to prevent the swing member 1 from shrinking during injection molding and ensure uniform thickness; the second reinforcing ribs 16 are used to prevent the two sides of the groove 15 from collapsing inward. Embodiment 2

[0063] This embodiment provides a hair clipper, as Figures 4-8 shown, including a housing 7, an inner housing 8, a moving cutter head 9, a stationary cutter head 91, a cutter pressing member 92, and a driving structure; the cutter pressing member 92 can elastically press the moving cutter head 9 movably against the stationary cutter head 91; the driving structure is the driving structure described in Embodiment 1.

[0064] During use, the driving device 6 is started to drive the moving cutter head 9 to swing left and right relative to the stationary cutter head 91, thereby realizing the hair cutting function. The hair clipper of this embodiment can reduce the motor load, improve the battery life, and reduce the loss of the driving device 6, thereby improving the service life of the hair clipper.

[0065] As Figure 7 shown, an installation head 17 is integrally formed at the other end of the swing member 1. The installation head 17 has a long strip opening 18 that penetrates both sides axially; the moving cutter head 9 has an installation position 93; the installation head 17 is elastically inserted into the installation position 93, thereby installing the swing member 1 and the moving cutter head 9 together.

[0066] As Figure 8 shown, two second installation through holes 43 are opened on the second installation plate 4, and two second internal thread blind holes 81 are opened on the inner housing 8 opposite to the second installation through holes 43. Second installation bolts pass through the second installation through holes 43 and are screwed with the second internal thread blind holes 81 to fixedly install the second installation plate 4 on the inner housing 8; installation claws 44 are provided on both sides of the second installation plate 4, and installation holes 82 are opened on the inner housing 8 opposite to the installation claws 44. The installation claws 44 can be installed into the installation holes 82.

[0067] Obviously, the above embodiments are only examples for clear illustration and are not limitations on the implementation manners. For those of ordinary skill in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to enumerate all the implementation manners here. And the obvious changes or modifications derived therefrom are still within the protection scope of this innovative technical solution.
