Description

Technical Field

[0001] This utility model relates to the field of hair clipper technology, and in particular to a flexible connection structure for a hair clipper motor. Background Technology

[0002] A hair clipper's blade consists of two parts: a fixed blade and a moving blade. A motor drives the moving blade to reciprocate relative to the fixed blade, thus cutting hair. Traditionally, the motor is fixed inside the clipper and directly connected to the moving blade. However, when the moving blade encounters significant resistance and cannot cut hair smoothly, the motor continues to drive it. This can easily cause the moving blade to detach from the fixed blade, resulting in hair getting stuck in the gap between the blades and pulling on the hair, affecting the user experience. It can even lead to blade deformation, damage to the blade connection parts, and motor overload, reducing the lifespan of the clippers. Utility Model Content

[0003] This invention provides a flexible connection structure for a hair clipper motor, which can improve user comfort.

[0004] To solve the above-mentioned technical problems, this utility model provides a flexible connection structure for a hair clipper motor, characterized in that it includes:

[0005] case;

[0006] An elastic connecting frame includes a fixed bracket, an elastic connector, and a mounting bracket. The elastic connecting frame is mounted on the housing via the fixed bracket, and the mounting bracket is connected to the fixed bracket via the elastic connector.

[0007] A drive motor, which is mounted on the mounting bracket;

[0008] A cutter head assembly, comprising a fixed cutter and a moving cutter, wherein the fixed cutter is mounted on the housing and the moving cutter is connected to the drive motor.

[0009] As a preferred embodiment of the above technical solution, the elastic connector can provide the drive motor with a degree of freedom. When the moving blade encounters excessive resistance, the degree of freedom allows the drive motor to move in the opposite direction to the moving blade.

[0010] As a preferred embodiment of the above technical solution, the elastic connector is a sheet-like structure, and the plane formed by the moving direction of the moving blade and the output shaft axis of the drive motor is perpendicular to the surface where the elastic connector is located.

[0011] As a preferred embodiment of the above technical solution, the elastic connector is provided with a first positioning slot, and the fixed bracket is provided with a first positioning protrusion, the first positioning protrusion being engaged in the first positioning slot.

[0012] As a preferred embodiment of the above technical solution, the elastic connector is provided with a second positioning slot, and the mounting bracket is provided with a second positioning protrusion, the second positioning protrusion being engaged in the second positioning slot.

[0013] As a preferred embodiment of the above technical solution, the housing is provided with a limiting groove, and both sides of the fixed bracket are provided with limiting blocks, which are inserted into the limiting groove.

[0014] As a preferred embodiment of the above technical solution, the housing is provided with a plurality of limiting posts, two of the limiting posts cooperate to form the limiting groove, and the limiting posts are provided with reinforcing ribs.

[0015] As a preferred embodiment of the above technical solution, the number of elastic connectors is two, and the fixed bracket, the mounting bracket, and the two elastic connectors cooperate to form a frame structure.

[0018] This utility model provides a flexible connection structure for a hair clipper motor, comprising: a housing, a flexible connecting frame, a drive motor, and a blade assembly. The drive motor is mounted on the housing via the flexible connecting frame. The blade assembly includes a fixed blade and a moving blade. The moving blade is driven by the drive motor. When cutting hair, the drive motor drives the moving blade to reciprocate relative to the fixed blade, achieving the cutting function. When the moving blade encounters excessive resistance and cannot cut normally, the drive motor continues to operate. However, under the action of resistance, the flexible connecting frame deforms, causing the drive motor to move slightly in the opposite direction. This prevents the moving blade from detaching from the fixed blade, thus avoiding hair getting stuck in the gap between the moving and fixed blades and pulling the hair, improving user comfort. Furthermore, it also prevents overloading of the drive motor and damage to the blade assembly due to excessive resistance, ensuring a smooth and stable cutting process and extending the service life of the hair clippers.

[0027] To make the objectives, features, and advantages of this utility model more apparent and understandable, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0028] See Figures 1 to 6 This utility model embodiment provides a flexible connection structure for a hair clipper motor, characterized in that it includes:

[0029] Casing 1;

[0030] The elastic connecting frame 2 includes a fixed bracket 3, an elastic connector 4, and a mounting bracket 5. The elastic connecting frame 2 is mounted on the housing 1 via the fixed bracket 3, and the mounting bracket 5 is connected to the fixed bracket 3 via the elastic connector 4.

[0031] A drive motor 6 is mounted on the mounting bracket 5;

[0032] The cutter head assembly 7 includes a fixed cutter and a moving cutter. The fixed cutter is mounted on the housing 1, and the moving cutter is connected to the drive motor 6.

[0033] This utility model embodiment provides a flexible connection structure for a hair clipper motor, including: a housing 1, a flexible connecting frame 2, a drive motor 6, and a blade assembly 7. The drive motor 6 is mounted on the housing 1 via the flexible connecting frame 2. The blade assembly 7 includes a fixed blade and a moving blade. The moving blade is connected to the drive motor 6 for transmission. When cutting hair, the drive motor 6 drives the moving blade to reciprocate relative to the fixed blade, achieving the cutting function. When the moving blade encounters excessive resistance and cannot cut normally, the drive motor 6 continues to operate. However, under the action of resistance, the flexible connecting frame 2 deforms, causing the drive motor 6 to move slightly in the opposite direction. This prevents the moving blade from detaching from the fixed blade, thus avoiding hair getting stuck in the gap between the moving blade and the fixed blade, which would cause hair pulling and improve user comfort. In addition, it also prevents the drive motor 6 from being overloaded and the blade assembly 7 from being damaged due to excessive resistance, ensuring a smooth and stable cutting process and extending the service life of the hair clippers.

[0034] In a further embodiment of this invention, the elastic connector 4 can provide the drive motor 6 with a degree of freedom. When the moving blade encounters excessive resistance, the degree of freedom allows the drive motor 6 to move in the opposite direction to the moving blade.

[0035] In this embodiment, the elastic connector 4 provides a degree of freedom to the drive motor 6. When the moving blade encounters excessive resistance (resistance that prevents the moving blade from moving further), this degree of freedom allows the drive motor 6 to slightly move in the opposite direction to the moving blade, thereby preventing the moving blade from detaching from the fixed blade and causing hair to get stuck in the gap between the moving blade and the fixed blade, resulting in hair pulling and improving user comfort. In addition, it also prevents the drive motor 6 from being overloaded and the blade assembly 7 from being damaged due to excessive resistance, ensuring a smooth and stable cutting process and extending the service life of the hair clippers.

[0036] In a further embodiment of this invention, the elastic connector 4 is a sheet-like structure, and the plane formed by the moving direction of the moving blade and the output shaft axis of the drive motor 6 is perpendicular to the plane where the elastic connector 4 is located.

[0037] In this embodiment, the elastic connector 4 is a sheet-like structure. The plane formed by the moving direction of the moving blade and the output shaft axis of the drive motor 6 is perpendicular to the plane where the elastic connector 4 is located. When the moving blade encounters excessive resistance, the sheet-like elastic connector 4 can bend along the plane formed by the moving direction of the moving blade and the output shaft axis of the drive motor 6, causing the drive motor 6 to move slightly in the opposite direction to the moving direction of the moving blade. At the same time, it can prevent the drive motor 6 from moving away from the fixed blade, thereby avoiding the gap between the moving blade and the fixed blade becoming too large during the slight movement of the drive motor 6, which would cause hair to get stuck in the gap between the moving blade and the fixed blade, resulting in hair pulling. This improves the comfort of use.

[0038] In a further embodiment of this invention, the elastic connector 4 is provided with a first positioning slot 401, and the fixed bracket 3 is provided with a first positioning protrusion 301, the first positioning protrusion 301 being engaged in the first positioning slot 401.

[0039] In this embodiment, the first end of the elastic connector 4 is provided with two symmetrically distributed first positioning slots 401, and the fixed bracket 3 is correspondingly provided with two symmetrically distributed first positioning protrusions 301. The two first positioning protrusions 301 are respectively engaged in the two first positioning slots 401. The elastic connector 4 and the fixed bracket 3 are fixedly connected by bolts. Since the elastic connector 4 can bend along a specific plane when the moving blade is subjected to resistance, the cooperation between the first positioning slots 401 and the first positioning protrusions 301, combined with the fixing effect of the bolts, ensures that the elastic connector 4 can still bend along a specific plane when bending. This can prevent the drive motor 6 from moving away from the fixed blade, and further prevent the gap between the moving blade and the fixed blade from becoming too large during the micro-movement of the drive motor 6. In addition, it can also improve the connection strength between the elastic connector 4 and the fixed bracket 3, thereby preventing the elastic connector 4 from fatigue deformation due to long-term use, which would lead to loosening of the connection, affect the cutting accuracy and stability, and thus further extend the overall service life of the hair clippers and improve the user experience.

[0040] In a further embodiment of this invention, the elastic connector 4 is provided with a second positioning slot 402, and the mounting bracket 5 is provided with a second positioning protrusion 501, which is engaged in the second positioning slot 402.

[0041] In this embodiment, the second end of the elastic connector 4 is provided with two symmetrically distributed second positioning slots 402, and the elastic bracket is correspondingly provided with two symmetrically distributed second positioning protrusions 501. The two second positioning protrusions 501 are respectively engaged in the two second positioning slots 402. The elastic connector 4 and the elastic bracket are fixedly connected by bolts. Since the elastic connector 4 can bend along a specific plane when the moving blade is subjected to resistance, the cooperation between the second positioning slots 402 and the second positioning protrusions 501, combined with the fixing effect of the bolts, ensures that the elastic connector 4 can still bend along a specific plane when bending. This can prevent the drive motor 6 from moving away from the fixed blade, and further prevent the gap between the moving blade and the fixed blade from becoming too large during the micro-movement of the drive motor 6. In addition, it can also improve the connection strength between the elastic connector 4 and the mounting bracket 5, thereby preventing the elastic connector 4 from fatigue deformation due to long-term use, which would lead to loosening of the connection, affect the cutting accuracy and stability, and thus further extend the overall service life of the hair clippers and improve the user experience.

[0042] In a further embodiment of this invention, a limiting groove 101 is provided on the housing 1, and limiting blocks 302 are provided on both sides of the fixing bracket 3, with the limiting blocks 302 inserted into the limiting groove 101.

[0043] In this embodiment, the housing 1 is provided with two limiting grooves 101, and the fixed bracket 3 is provided with limiting blocks 302 on both sides. The two limiting blocks 302 are respectively embedded in the two limiting grooves 101. The fixed bracket 3 and the housing 1 are fixedly connected by bolts. Combined with the cooperation of the limiting grooves 101 and the limiting blocks 302, the movement of the fixed bracket 3 is effectively restricted, further ensuring the relative position stability of the moving blade and the fixed blade, improving the cutting accuracy, and extending the service life. In addition, it can also improve the connection strength between the fixed bracket 3 and the housing 1, prevent displacement caused by vibration or external force, ensure the stability and safety of the cutting process, thereby further optimizing the overall performance of the hair clippers and enhancing the user's comfort.

[0044] In a further embodiment of this invention, the housing 1 is provided with a plurality of limiting posts 102, two of the limiting posts 102 cooperate to form the limiting groove 101, and the limiting posts 102 are provided with reinforcing ribs 103.

[0045] In this embodiment, four limiting posts 102 are evenly distributed on the housing 1, and two limiting posts 102 form a limiting groove 101. The limiting posts 102 and the housing 1 are integrally injection molded, and the limiting posts are provided with reinforcing ribs 103, thereby further increasing the structural strength of the limiting posts 102, thus ensuring the structural strength of the limiting groove 101, effectively preventing the fixed bracket 3 from displacing during the cutting process, further stabilizing the relative position of the moving blade and the fixed blade, improving cutting accuracy and stability, extending the service life of the hair clippers, and optimizing the user experience.

[0046] In a further embodiment of this invention, the number of elastic connectors 4 is two, and the fixed bracket 3, the mounting bracket 5, and the two elastic connectors 4 cooperate to form a frame structure.

[0047] In this embodiment, the elastic connectors 4 are respectively arranged on both sides of the mounting bracket 5. Through double elastic support, the drive motor 6 obtains a more balanced support force during operation, reduces vibration and offset, ensures a constant gap between the moving blade and the fixed blade, further improves shearing accuracy, extends service life, and enhances user comfort.

[0048] In a further embodiment of this invention, the two elastic connectors 4 are arranged parallel to each other.

[0049] In this embodiment, the two elastic connectors 4 are arranged in parallel to each other. The parallel layout enhances the stability of the overall structure, further disperses the stress during the shearing process, reduces fatigue damage at a single connection point, ensures the long-term stability of the relative position of the moving blade and the fixed blade, improves shearing accuracy and durability, and optimizes the user experience.

[0050] In a further embodiment of this invention, the mounting bracket 5 is provided with a mounting part 502, the mounting part 502 is provided with a clearance hole 503 in the middle, and a stepped positioning part 504 is provided in the clearance hole 503.

[0051] In this embodiment, the drive motor 6 and the mounting part 502 are fixedly connected by bolts to ensure a firm and reliable connection and reduce loosening caused by vibration. The mounting part 502 is provided with a clearance hole 503 in the middle, through which the output shaft of the drive motor 6 passes. A stepped positioning part 504 is provided in the clearance hole 503 to accurately fix the position of the output shaft, further ensuring the stability and accuracy of the cutting process and improving the overall performance of the hair clippers and the user experience.
