Description

Technical Field

[0001] This utility model relates to the field of shaver technology, and in particular to an integrated drive mechanism and a shaver. Background Technology

[0002] Existing electric shaver drive mechanisms are typically assembled from multiple independent parts, including separate drivers, swing arms, and spring return mechanisms. This modular structure has several drawbacks: First, the large number of parts leads to complex manufacturing processes, low assembly efficiency, and high production costs. Second, assembly errors and clearances exist between the parts, which can easily generate additional vibration and noise under long-term high-speed reciprocating motion of the swing arm, affecting the user experience and product lifespan. Utility Model Content

[0003] In order to solve the above-mentioned technical problems, the purpose of this utility model is to provide a drive mechanism and a shaver, which solves the problems of complicated assembly and need to optimize the operating noise of existing shaver drive mechanisms.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows: an integrated drive mechanism, including a swing arm for connecting the cutter head; a guide mechanism for converting the rotational motion of the driver into the reciprocating linear swing of the swing arm; and an elastic arm for connecting the swing arm and the base to provide elastic buffering and elastic restoring force when the swing arm reciprocates. The swing arm, the elastic arm, and the driver are integrally formed.

[0005] Furthermore, the drive includes a motor and a base supporting the motor, with the base, swing arm, and elastic arm integrally molded to form a frame covering the outside of the motor.

[0006] By adopting the above technical solution, the integral molding scope is limited to the base, swing arm, and elastic arm, thus forming an integrated frame covering the motor. The beneficial effects of this structure are multifaceted: First, the frame constitutes a robust protective framework, improving the product's mechanical strength and anti-interference capabilities; second, it highly integrates the drive's support function (base), transmission function (swing arm), and buffering function (elastic arm) into a single unit, achieving maximum space utilization and making the entire drive mechanism very compact, which is conducive to the miniaturization and thinning design of the product; third, it provides a precise positioning reference for motor installation, ensuring the relative positional accuracy of the motor shaft and the entire transmission system, thereby guaranteeing transmission efficiency and operational stability.

[0007] Furthermore, the guiding mechanism includes a guide hole on the swing arm and an eccentric shaft that slides in the guide hole. The eccentric shaft is driven by a motor, and when it makes a circular motion around the axis of the motor, it drives the swing arm to swing linearly back and forth.

[0008] By adopting the above technical solution, the classic and efficient conversion mechanism using an eccentric shaft and guide hole has the following advantages: This mechanism uses simple mechanical principles to efficiently and reliably convert the rotational motion of the motor into the linear reciprocating oscillation required by the swing arm. The motion conversion efficiency is high and the energy loss is small. The sliding fit of the eccentric shaft in the guide hole can automatically cancel the radial component in the rotational motion, thereby ensuring that the swing arm outputs pure high-frequency linear oscillation. This is the ideal motion form for driving the cutting head to achieve efficient shearing action. The structure is mature and reliable, easy to process and manufacture, and helps to control costs.

[0009] Furthermore, the frame is located on the radial outer side of the motor, and the swing arm is provided with an extension part arranged along the motor axis. The guide hole is correspondingly provided on the extension part, and the setting direction of the guide hole and the reciprocating motion direction of the swing arm are perpendicularly intersecting each other on the radial section of the motor.

[0010] By adopting the above technical solution, the frame is placed on the radial outside of the motor, making the most of the idle space around the motor and reflecting the concept of compact design. The axial extension is set on the swing arm and the guide hole is set on it, which is equivalent to optimizing the point of application of the power transmission of the swing arm. This makes it easier for the motor, which is set along the front-to-back direction of the product, to form a transmission connection with the upper end of the swing arm along the left-to-right direction of the product.

[0011] Furthermore, the sidewall of the guide hole is formed with an elastic part, which is configured to maintain an interference fit between the guide hole and the eccentric shaft in the swing direction of the swing arm.

[0012] By adopting the above technical solution, the sidewall of the guide hole has a certain elastic deformation capacity, which can always maintain an interference fit with the eccentric shaft. This dynamic interference fit completely eliminates the fit clearance that is inevitably caused by wear in traditional rigid fits. This effectively optimizes a series of problems caused by clearance, such as impact shaking, increased noise, and decreased transmission accuracy. It achieves the effect of "self-adaptive wear", that is, after long-term use, the elastic part can continue to hold the eccentric shaft tightly, ensuring consistent transmission accuracy and smoothness. This greatly improves the durability of the product and the consistency of user experience, and is an improvement that significantly extends the product life.

[0013] Furthermore, the extension is provided with an auxiliary hole, which is located on the side of the guide hole, and an elastic part is formed between the guide hole and the auxiliary hole.

[0014] By adopting the above technical solution, the structure is simple and easy to process. It does not require the introduction of additional parts or complex processes. The corresponding structure can be designed on the mold and completed in one injection molding, which hardly increases the production cost. The shape, size and position of the auxiliary holes can be flexibly designed, so as to precisely control the elastic coefficient and deformation range of the elastic part to adapt to the needs of different motor models and swing parameters. The design has a high degree of freedom and wide adaptability. In addition, by adding auxiliary holes, the weight of the extension can also be reduced, which makes it easier for the eccentric shaft to drive the swing arm during operation. This is a clever design that achieves key functions with a minimalist structure, which is both efficient and economical.

[0015] Furthermore, both ends of the motor's axial direction are connected to eccentric shafts, and two corresponding frames are provided, with the two frames spaced apart along the motor's axial direction outside the motor.

[0016] By adopting the above technical solution, in this embodiment, the motor is an axial motor with eccentric shafts at both ends of its axial direction, thereby enabling one motor to drive two swing arms to reciprocate, which doubles the effective cutting area of ​​the razor or shaver, greatly improving the efficiency of haircutting or shaving. More importantly, the two symmetrically arranged drive mechanisms can balance the inertial force generated by each other in high-speed reciprocating motion, thereby greatly offsetting the vibration of the whole machine, making the equipment run exceptionally smoothly and feel comfortable, achieving a perfect combination of high efficiency and quietness.

[0017] Furthermore, the two frames are connected by connectors.

[0018] By adopting the above technical solution, the connector connects the two independent frames into a relatively stable overall frame. This ensures that the two swing arm mechanisms can always maintain precise synchronous movement on the same plane, guaranteeing uniform force and consistent shearing effect when the double cutter heads are working. In addition, the integrated frame structure facilitates overall handling and installation, further simplifying the assembly process of the final product.

[0019] Furthermore, the base has a mounting slot that matches the shape of the motor, and the motor is installed in the mounting slot accordingly.

[0020] By adopting the above technical solution, the placement slot effectively constrains the motor in both the circumferential and radial directions, ensuring the relative positional accuracy between the motor shaft and the entire drive mechanism (especially with the guide hole on the swing arm). This fundamentally guarantees the precision and consistency of power transmission, avoiding problems such as uneven wear, abnormal noise, and efficiency loss caused by motor installation deviations. Secondly, this interlocking structure greatly simplifies the assembly process. Operators only need to place the motor directly into the placement slot to quickly complete the initial positioning without complicated adjustment procedures, significantly improving production efficiency and product consistency. At the same time, this tight fit also increases the contact area between the motor and the base, which not only enhances structural stability and heat dissipation performance but also more effectively suppresses the transmission of minor vibrations and electromagnetic noise during motor operation to the outside, further improving the overall machine's operational smoothness and quietness, and reinforcing the core advantages brought by the integrated design.

[0021] A razor including the aforementioned integrated drive mechanism.

[0022] By adopting the above technical solution and utilizing the innovative drive mechanism described in the preceding claims, the shaver naturally inherits all the technological advantages, including but not limited to: lower operating noise, less vibration, stronger and more precise cutting power, longer service life, simpler assembly, and lower cost. These advantages ultimately translate into core competitiveness for the product, bringing users a more comfortable, efficient, and durable user experience, and giving the shaver significant technological advantages and commercial value in the market.

[0023] Compared with the prior art, the advantages of this utility model are:

[0024] This invention creatively proposes a compact structure that integrates the actuator, swing arm, and elastic arm into one piece. This integrated design brings advantages: First, it greatly reduces the number of parts and assembly steps, simplifies the production process, significantly reduces manufacturing costs and assembly errors, and improves production efficiency and product consistency.

[0025] Secondly, since the swing arm and the elastic arm are made from the same base material, the connection between them is seamless and gapless. This fundamentally eliminates the abnormal noise and additional vibration caused by the fit tolerance after multiple parts are assembled, making the mechanism run more smoothly and with lower noise.

[0026] Finally, the elastic arm not only serves as an elastic element that provides the restoring force, but it is also part of the overall structure. This design makes the overall structure of the drive mechanism more rigid, the power transmission more direct and efficient, and the response more rapid. At the same time, it avoids the risk of fatigue detachment or failure that may occur with independent springs, greatly improving the reliability and service life of the product.

[0037] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments.

[0038] Reference Figure 1 and 2This is an integrated drive mechanism commonly used in shavers, such as electric clippers and shavers. It includes a driver, a swing arm 12, a guide mechanism, and an elastic arm 11. The swing arm 12 connects to the moving head 5. The driver drives the swing arm 12 to reciprocate via the guide mechanism, thereby achieving the reciprocating oscillation of the moving head 5. The elastic arm 11 acts elastically in the direction of movement of the swing arm 12, providing elastic buffering and elastic reset of the swing arm 12 during its reciprocating oscillation. The swing arm 12, elastic arm 11, and driver are integrally formed, offering the following advantages: First, it greatly reduces the number of parts and assembly steps, simplifies the manufacturing process, and significantly reduces manufacturing costs. This design reduces costs and assembly errors, improving production efficiency and product consistency. Secondly, since the swing arm 12 and the elastic arm 11 are made from the same base material, their connection is seamless and gapless. This fundamentally eliminates abnormal noises and additional vibrations caused by fit tolerances after assembling multiple parts, making the mechanism run more smoothly and with lower noise. Finally, the elastic arm 11 not only serves as an elastic element providing restoring force but is also part of the overall structure. This design makes the overall structure of the drive mechanism more rigid, the power transmission more direct and efficient, and the response more rapid. At the same time, it avoids the risk of fatigue detachment or failure that may occur with independent springs, greatly improving the reliability and service life of the product.

[0039] In this embodiment, a razor is used as an example, referring to... Figure 4 It generally includes a housing (not shown), a moving blade head 5, a fixed blade head (not shown), and a connecting part 4. The aforementioned integrated drive mechanism is installed inside the housing. The fixed blade head is fixedly installed on the housing through a corresponding fixed blade holder, while the moving blade head 5 is connected to the swing arm 12 through the connecting part 4. In this way, when the driver drives the swing arm 12 to reciprocate through the guide mechanism, the moving blade head 5 can be driven to reciprocate on the side of the fixed blade head through the connecting part 4 to achieve the hair trimming function.

[0040] In this embodiment, the driver includes a motor 3 and a base 13 supporting the motor 3. The base 13, the swing arm 12, and the elastic arm 11 are integrally formed to form a frame 1 covering the outside of the motor 3. The advantage of this is that the integrally formed area is limited to the base 13, the swing arm 12, and the elastic arm 11, thus forming an integral frame 1 covering the outside of the motor 3. The beneficial effects of this structure are multifaceted: First, the frame 1 constitutes a robust protective frame, improving the mechanical strength and anti-interference ability of the product; Second, it highly integrates the driver's support function (base 13), transmission function (swing arm 12), and buffering function (elastic arm 11) into one unit, achieving maximum space utilization and making the entire drive mechanism very compact, which is conducive to the miniaturization and thinning design of the product; Third, it provides a precise positioning reference for the installation of the motor 3, ensuring the relative positional accuracy of the motor 3 shaft and the entire transmission system, thereby ensuring transmission efficiency and working stability.

[0041] In this embodiment, the elastic arm 11 is flat in shape, and its bending direction is in the same direction as the movement direction of the swing arm 12, so as to take advantage of the good flexibility of the thin-walled part of the elastic arm 11 to provide elastic buffering and restoring force for the swing arm 12.

[0042] In this embodiment, for ease of description, the length, width, and height are referenced in this document. Figure 1 For example.

[0043] In this embodiment, the frame 1 is located on the radial outer side of the motor 3, the motor 3 is arranged along the width direction of the frame 1, the swing arm 12 is located on the radial upper end of the motor 3, the elastic arm 11 is located on both sides of the motor 3, and the base 13 is located on the lower end of the motor 3.

[0044] As a specific embodiment of the guiding mechanism, it includes a guide hole 1211 provided on the swing arm 12 and an eccentric shaft 33 slidably provided in the guide hole 1211. The eccentric shaft 33 is driven by the motor 3, and when it makes a circular motion around the axis of the motor 3, it drives the swing arm 12 to swing linearly back and forth.

[0045] Specifically, the swing arm 12 has extensions 121 at both ends along the axial direction of the motor 3. The extensions 121 have guide holes 1211 along the height direction of the frame 1. The eccentric shaft 33 of the motor 3 is slidably disposed in the guide holes 1211. When the eccentric shaft 33 makes a circular motion, its component in the height direction is neutralized by the sliding of the eccentric shaft 33 in the guide holes 1211. The swing arm 12 will not move in the height direction, but will only swing back and forth along the length direction of the frame 1.

[0046] In this embodiment, the orientation of the guide hole 1211 is perpendicular to the reciprocating motion direction of the swing arm 12 on the radial section of the motor 3. This angle setting facilitates the swing arm 12 to maintain a stable linear displacement under the drive of the eccentric shaft 33.

[0047] In this embodiment, the shaver can be a single-head shaver, a double-head shaver, or other multi-head shaver. This embodiment takes a double-head shaver as an example. The corresponding frame 1 is provided with two parts, and its base 13 is fixedly installed on the shaver's housing. The motor 3 is located inside the housing along the width direction of the frame 1. The motor 3 has output shafts 31 at both ends of its axial direction. The output shafts 31 are connected to eccentric shafts 33 through eccentric wheels 32. When the motor 3 drives the output shafts 31, it synchronously drives the two eccentric wheels 32 to rotate, thereby driving the eccentric shafts 33 to perform circular motion around the rotation axis of the output shafts 31, so as to drive the two frame-shaped swing arms 12 to swing back and forth.

[0048] Motor 3 can be a brushed motor, a brushless motor, or a motor motor. It can be an internal rotor motor or an external rotor motor, as long as it has an eccentric shaft 33 and can drive the swing arm 12 to reciprocate. It can also be other components or mechanisms. In this embodiment, an external rotor motor 3 is taken as an example (refer to...). Figure 3 Since it is existing technology, only its composition features are briefly described here. The motor 3 includes a rotor housing 301, a magnet 302, and a stator 303 of the motor 3. The stator 303 is fixed inside the rotor housing 301 and is mounted on the base 13 through a stator bracket 304. The rotor housing 301 is connected to the output shaft 31 to drive the output shaft 31 to rotate.

[0049] In this embodiment, refer to Figure 2 and 3 The base 13 has an embedded groove 133 at the bottom of the stator bracket 304, and the lower end of the stator bracket 304 is inserted into the embedded groove 133 to fix the stator bracket 304 and the base 13.

[0050] Based on the above embodiments, the eccentric shafts 33 at both ends of the motor 3 axis are symmetrically arranged at both ends of the output shaft 31 with the axis of the output shaft 31 as the line of symmetry. The advantage of this is that when the output shaft 31 of the motor 3 rotates, the output shaft 31 drives the two swing arms 12 to move synchronously and in opposite directions through the two eccentric shafts 33 respectively. This can effectively reduce the vibration of the two swing arms 12 during reciprocating motion and achieve the effect of noise reduction and vibration damping.

[0051] In this embodiment, in order to improve the overall integrity of the two frames 1, the two bases 13 arranged along the axial direction of the motor 3 are connected by a connector 2. The specific connection method is as follows: the bottom of the connector 2 is provided with a pin 21 and a screw hole 22, and the base 13 of the two frames 1 are provided with a corresponding insertion hole 131 and a screw hole 22. The connector 2 is inserted into the insertion hole 131 through the pin 21, and then the screws are passed through the screw holes 22 in sequence, so that the combination connection of the two frames 1 can be quickly completed. Of course, the bases 13 of the two frames 1 can also be integrally formed.

[0052] Furthermore, in this embodiment, the base 13 of the two frames 1 is provided with a placement groove 132 that matches the shape of the motor 3. Part of the motor 3 is correspondingly placed in the placement groove 132. In this way, the radial length direction and both ends of the axial direction of the motor 3 are limited by the placement groove 132, avoiding problems such as uneven wear, abnormal noise and efficiency loss caused by installation deviation of the motor 3. Secondly, this interlocking structure greatly simplifies the assembly process. The operator only needs to put the motor 3 directly into the placement groove 132 to quickly complete the initial positioning without complicated adjustment procedures, which significantly improves production efficiency and product consistency. At the same time, this tight fit also increases the contact area between the motor 3 and the base 13, which not only enhances the structural stability and heat dissipation performance, but also more effectively suppresses the transmission of minor vibrations and electromagnetic noise of the motor 3 to the outside during operation, further improving the overall running stability and quietness of the machine, and strengthening the core advantages brought by the integrated design.

[0053] Based on the above embodiments, in order to optimize the volume of the combination of the frame 1 and the motor 3, an avoidance groove 123 can be set at the bottom of the swing arm 12 corresponding to the position of the motor 3. By setting the avoidance groove 123, the height of the frame 1 can be made lower, and the problem of friction and collision between the swing arm 12 and the motor 3 will not occur, thus effectively optimizing the volume of the drive mechanism.

[0054] To avoid gaps caused by long-term wear between the eccentric shaft 33 and the guide hole 1211, which could affect the normal transmission and noise stability of the product, this embodiment provides an elastic part 1213 on the side wall of the guide hole 1211. By designing the side wall of the guide hole 1211 to have a certain elastic deformation capability, it can always maintain an interference fit with the eccentric shaft 33. This dynamic interference fit completely eliminates the gaps that inevitably occur due to wear in traditional rigid fits, thereby effectively optimizing a series of problems such as impact shaking, increased noise, and decreased transmission accuracy caused by gaps. It achieves the effect of "self-adaptive wear," meaning that after long-term use, the elastic part 1213 can continuously hold the eccentric shaft 33, ensuring consistent precision and smooth transmission, greatly improving the durability of the product and the consistency of user experience. This is an improvement that significantly extends the product's lifespan.

[0055] Specifically, as a specific embodiment of the elastic part 1213, auxiliary holes 1212 can be opened on both sides of the guide hole 1211, and the extension between the auxiliary hole 1212 and the guide hole 1211 is used as the elastic part 1213. This not only makes processing convenient, but also eliminates the need to introduce additional parts or complex processes. The corresponding structure can be designed on the mold and completed in one injection molding, with almost no increase in production costs.

[0056] In this embodiment, the shape, size and position of the auxiliary hole 1212 can be flexibly designed, thereby precisely controlling the elastic coefficient and deformation range of the elastic part 1213 to adapt to the needs of different models of motors 3 and swing parameters. The design has a large degree of freedom and wide adaptability. Furthermore, by adding the auxiliary hole 1212, the weight of the extension part 121 can also be reduced, which makes it easier for the eccentric shaft 33 to drive the swing arm 12 during operation. This is a clever design that achieves key functions with a minimalist structure, combining high efficiency and economy.

[0057] Based on the above embodiments, the elastic part 1213 can also be an elastic paddle, compression spring, spring, elastic rubber or other elastic part 1213 provided on the extension 121 in the swing direction of the swing arm 12. As long as the gap between the eccentric shaft 33 and the guide hole 1211 in the movement direction of the swing arm 12 is reduced, so as to keep the eccentric shaft 33 and the guide hole 1211 always in contact in the swing direction of the swing arm 12, the elastic part 1213 can also be other components or mechanisms.

[0058] In this embodiment, the core function of the elastic part 1213 is to apply preload to eliminate the play between the eccentric shaft 33 and the guide hole of the swing arm 12 in the swing direction, ensuring precise and smooth power transmission and reducing wear and operating noise. To achieve this goal, the fit between the diameter of the eccentric shaft 33 and the dimensions of the guide hole 1211 in the movement direction of the swing arm 12 is crucial. In mechanical design, the fit between the shaft and the hole is mainly divided into three types: clearance fit (the size of the hole is always larger than the size of the shaft, and there is a guaranteed clearance between them), interference fit (the size of the hole is always smaller than the size of the shaft, and after assembly, the two are firmly joined without relative movement), and transition fit (the dimensional tolerance between the hole and the shaft may produce a small gap). (A slight interference fit may occur, which is a state between the two). This product adopts a precise interference fit or transition fit design. Its purpose is to completely eliminate the shaking, impact and noise caused by gaps through the tight combination of zero or negative gap between the shaft and the hole, thereby improving shaving efficiency and product life. Simply put, no matter what kind of fit method, the ultimate goal is to ensure that the eccentric shaft 33 and the guide hole 1211 are tightly connected in the direction of movement to achieve gapless power transmission. Therefore, the interference fit described in the patent, as long as it can reduce the wear gap between the guide hole 1211 and the eccentric shaft 33 and keep them in close contact, also includes clearance fit and transition fit.

[0059] In this embodiment, the guide hole 1211 is not limited to the literal through hole structure; it can also be a "slot" hole, and is not limited to the through hole form.

[0060] In the above embodiments, the driving method of the swing arm 12 is based on the motor 3 as the power source, which drives the eccentric shaft 33 to move in the guide hole 1211 on the swing arm 12, thereby realizing the reciprocating motion of the motor 3. Of course, it can be imagined that as long as the rotational motion of the motor 3 can be converted into the reciprocating motion of the swing arm 12, its guiding mechanism can also be a linkage transmission mechanism or other mechanisms, which will not be elaborated here.

[0061] It is conceivable that the driving method for the swing arm 12 can also adopt the existing common magnetic drive swing motor 3. Its working principle is: the energized electromagnetic coil generates a changing magnetic field, which interacts with the permanent magnets (like poles repel, unlike poles attract) carefully arranged inside the shaver, thereby generating a force to push or pull the swing arm 12, and also realizing the reciprocating motion of the swing arm 12. Therefore, inspired by the integrated molding of the driver, the swing arm 12 and the elastic arm 11, the driving method for the swing arm 12 can also be other forms, which will not be elaborated here.

[0062] Although the preferred embodiments of the present invention have been described in detail above, it should be clearly understood that various modifications and variations can be made to the present invention by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
