[0042] The utility model provides an electric shearing device, which can be an electric shaver, an electric shaver, an electric hair clipper, etc.

[0043] Please refer to Figures 1 to 7 The electric shearing device 100 proposed in the present invention includes a main body shell 10, a mounting bracket 20, a power supply component 30 and a circuit board 40.

[0044] The main housing 10 provides protection and support for the internal components of the electric shearing device 100, ensuring their safety and stability. The main housing 10 defines a cavity 11, within which the power supply assembly 30, mounting bracket 20, and circuit board 40 are housed. The main housing 10 may be shaped, but is not limited to, a rectangular parallelepiped, a cylinder, or shapes similar to a rectangular parallelepiped or cylinder. The main housing 10 may be made of ABS plastic, engineering plastics, or high-strength, wear-resistant metal materials such as aluminum alloy.

[0045] The mounting bracket 20 is a support structure that secures the power supply assembly 30, circuit board 40, and other components. The mounting bracket 20 has a mounting slot 21, with the slot opening facing the inner wall of the main housing 10. The power supply assembly 30 is positioned within the mounting slot 21. The mounting slot 21 ensures the stability and security of the power supply assembly 30. The mounting bracket 20 is typically made of lightweight yet sturdy plastic or metal.

[0046] The power supply assembly 30 is the power source of the electric shearing device 100, providing power support for the electric shearing device 100 to ensure continuous and stable operation of the device. The power supply assembly 30 includes but is not limited to lithium-ion batteries, nickel-metal hydride batteries, nickel-cadmium batteries, and lithium polymer batteries.

[0047] The circuit board 40 is an electronic component that controls and manages the shearing device. The circuit board 40 covers the notch of the installation groove 21 and is connected to the installation bracket 20. At this time, the circuit board 40 can prevent the power supply component 30 from disengaging from the notch of the installation groove 21, reducing the risk of displacement or damage of the power supply component 30 caused by vibration or impact.

[0048] In the related art, a circuit board is usually arranged on one side of the installation bracket, and an assembly groove is arranged on the other side of the installation bracket. The power supply component is embedded in the assembly groove and fixed by means of tape or the like to prevent the power supply component from disengaging from the assembly groove. This setting increases the assembly difficulty, reduces the assembly efficiency, and at the same time, the power supply component and the circuit board are far apart, resulting in too long connection cables between the two, occupying too much internal space, thereby increasing the volume of the electric shearing device.

[0049] The electric shearing device 100 proposed by the present utility model includes a main body shell 10, an installation bracket 20, a power supply component 30, and a circuit board 40. The main body shell 10 has a cavity 11, and the power supply component 30, the installation bracket 20, and the circuit board 40 are all arranged inside the main body shell 10. The installation bracket 20 is provided with an installation groove 21, the notch of the installation groove 21 faces the inner side wall of the main body shell 10, and the power supply component 30 is arranged in the installation groove 21. The circuit board 40 covers the notch of the installation groove 21 and is connected to the installation bracket 20. The present utility model can first assemble the power supply component 30, the installation bracket 20, and the circuit board 40 into an integral body and then assemble it into the main body shell 10. The structure is simple and the assembly efficiency is high; the circuit board 40 covers the notch of the installation groove 21 to prevent the power supply component 30 from disengaging from the installation groove 21, reducing the number of components inside the electric shearing device 100, and after assembly, the layout of each component is compact, which can effectively utilize the internal space of the main body shell 10, reduce the volume, and make the overall structure more compact.

[0050] In an embodiment, please refer to Figures 2 to 5 , the main body shell 10 is provided with an opening communicating with the cavity 11 at the top in the longitudinal direction; the installation bracket 20, the power supply component 30, and the circuit board 40 are installed in the cavity 11 together along the longitudinal direction from the opening.

[0051] In this embodiment, the main body shell 10 is provided with an opening at the top in the longitudinal direction, and this opening communicates with the cavity 11. During assembly, first install the power supply component 30 into the installation groove 21 of the installation bracket 20, and then connect the circuit board 40 to the installation bracket 20, thereby assembling the power supply component 30, the installation bracket 20, and the circuit board 40 into an integral body. Then, install the assembled integral body into the cavity 11 together along the longitudinal direction through the opening at the top of the main body shell 10. The structure is simple and the assembly efficiency is high.

[0052] In an embodiment, please refer to Figure 8 、 Figure 9, the mounting bracket 20 includes a connecting portion 23 and two power supply compartments 22 connected to opposite sides of the connecting portion 23 in the first direction. Each power supply compartment 22 is provided with a mounting groove 21, and the notch of the mounting groove 21 faces along the second direction; the power supply assembly 30 includes a first power supply 31 and a second power supply 32, and the first power supply 31 and the second power supply 32 are respectively arranged in the two mounting grooves 21; wherein, the longitudinal direction, the first direction and the second direction are perpendicular to each other in pairs.

[0053] In this embodiment, the mounting bracket 20 includes two power supply compartments 22 and a connecting portion 23. The two power supply compartments 22 are connected to opposite sides of the connecting portion 23, that is, the two power supply compartments 22 are symmetrically arranged on opposite sides of the connecting portion 23. The symmetrical layout of the two power supply compartments 22 helps to improve the stability of the device in different directions. Especially when used vertically or obliquely, it can reduce the tilt or displacement caused by gravity. The power supply assembly 30 includes a first power supply 31 and a second power supply 32, and they are respectively arranged in the two mounting grooves 21. The first power supply 31 and the second power supply 32 provide power for the electric shearing device 100, which increases the capacity of the power supply assembly 30, and thus improves the battery life of the electric shearing device 100.

[0054] Furthermore, the length of the mounting groove 21 in the longitudinal direction is greater than the length in the first direction and the length in the second direction.

[0055] In this embodiment, the mounting groove 21 extends in the longitudinal direction, and its length in the longitudinal direction is greater than the length in the first direction and the length in the second direction. In this way, the size of the electric shearing device 100 in the first direction and the second direction can be reduced, thereby reducing the volume of the electric shearing device 100.

[0056] Furthermore, the notches of the two mounting grooves 21 are arranged on the same side of the mounting bracket 20, and the circuit board 40 covers the notches of the two mounting grooves 21.

[0057] In this embodiment, please refer to Figure 9 , the notches of the two mounting grooves 21 are arranged on the same side of the mounting bracket 20, and the circuit board 40 covers the notches of the two mounting grooves 21 at the same time. In this way, the structure can be simplified, the assembly process can be simplified, and the assembly efficiency can be improved. In some other embodiments, the notches of the two mounting grooves 21 may not be arranged on the same side of the mounting bracket 20, and two circuit boards 40 can be used to cover the notches of the two mounting grooves 21 respectively. In this way, the functions of the two circuit boards 40 can be separated, the mutual interference can be reduced, and the stability and reliability of the system can be improved; the circuit board 40 with problems can be repaired or replaced separately, reducing the maintenance cost and time.

[0058] In one embodiment, the circuit board 40 is detachably connected to the mounting bracket 20. The detachable connection includes, but is not limited to, threaded connection, plug-in connection, snap connection, magnetic connection, etc. The detachable connection of the circuit board 40 to the mounting bracket 20 simplifies the assembly process and improves production efficiency. At the same time, the detachable circuit board 40 makes maintenance and replacement more convenient.

[0059] Further, please refer to Figure 7 and Figure 9 , the mounting bracket 20 further includes a plurality of plug-in portions 24, and the plurality of plug-in portions 24 protrude from the side surface of the mounting bracket 20 where the notch is located; at least one plug-in portion 24 is provided on the bottom side of the mounting bracket 20 in the longitudinal direction, and at least one plug-in portion 24 is provided on the opposite two edges of the mounting bracket 20 in the first direction; the circuit board 40 slides longitudinally from the top side of the mounting bracket 20 between the plurality of plug-in portions 24 to cover the notch.

[0060] In this embodiment, the plug-in portion 24 can be a card slot, and the edge of the circuit board 40 can be inserted into the card slot to achieve limiting and fixing. The plug-in portion 24 can also be a buckle, and when the circuit board 40 is inserted, the buckle will lock the circuit board 40 to prevent it from slipping out. The plug-in portion 24 protrudes from the side surface of the mounting bracket 20 where the notch is located and is located on the outer edge of the mounting bracket 20, so that the main working area of the cavity 11 is not occupied, and thus the space can be utilized more effectively and other internal components can be avoided from being interfered.

[0061] The circuit board 40 slides longitudinally from the top side of the mounting bracket 20 between the plurality of plug-in portions 24 to cover the notch. This installation method means that during the assembly process, the circuit board 40 will naturally slide to the correct position by gravity and ensure the accuracy and stability of the connection through limiting cooperation. Compared with other assembly methods, such as forced pressing or using tools for fixing, gravity assembly is more gentle. This helps to reduce problems caused by excessive stress or damage of parts and extends the service life and reliability of the equipment.

[0062] Further, please refer to Figure 9 , each plug-in portion 24 includes a connecting section 241 connected to the mounting bracket 20 and a limiting section 242 connected to one end of the connecting section 241 away from the mounting bracket 20, and the limiting section 242 is used to abut against the board surface of the circuit board 40 facing away from the mounting bracket 20.

[0063] In this embodiment, by abutting the limiting section 242 against the circuit board 40, the movement of the circuit board 40 on the mounting bracket 20 can be reduced, thereby improving the stability of the entire system. At the same time, the connecting section 241 and the limiting section 242 form a card slot, and the edges of the circuit board 40 are inserted into the plurality of card slots, which can simplify the assembly process of the circuit board 40, and the presence of the limiting section 242 makes it easier for the circuit board 40 to be aligned and fixed on the mounting bracket 20.

[0064] Further, please refer to Figure 7 and Figure 9 , the mounting bracket 20 further includes two guide plates 221 protruding from the side surfaces where the notch of the mounting bracket 20 is located, and the two guide plates 221 are respectively arranged at opposite edges of the mounting bracket 20 in the first direction.

[0065] In this embodiment, the guide plates 221 define the assembly path of the circuit board 40 longitudinally, simplifying the installation steps of the circuit board 40. At the same time, the guide plates 221 provide stability and safety for the assembly in the first direction. Specifically, both sides of the circuit board 40 in the first direction are in limit fit with the two guide plates 221, and the guide plates 221 limit the movement of the circuit board 40, reducing accidents that may occur during the assembly process, such as accidental detachment or misoperation of the circuit board 40.

[0066] Further, the outer surface of the guide plate 221 in the longitudinal direction is flush with or equal to the outer surface of the circuit board 40 in the longitudinal direction. In this way, it is possible to avoid contact between the circuit board 40 and the main body case 10 or other hard surfaces, preventing scratching or damage. At the same time, the guide plate 221 can be more easily recognized and operated by automated equipment, which helps to achieve automated assembly.

[0067] In one embodiment, Figures 2 to 6 , the electric shearing device 100 further includes an upper cover 60, and the upper cover 60 covers the opening; the mounting bracket 20 is connected to the upper cover 60, and the top side of the circuit board 40 in the longitudinal direction can abut against the upper cover 10.

[0068] In this embodiment, compared with connecting the mounting bracket 20 to the inner wall (inner side wall or bottom wall) of the cavity 11, connecting the mounting bracket 20 to the upper cover 60, since the upper cover 60 is outside the cavity 11, the connection between the mounting bracket 20 and the upper cover 60 is more convenient, without the need to operate inside the cavity 11, improving the assembly efficiency. And the top side of the circuit board 40 in the longitudinal direction can abut against the upper cover 10, and the upper cover 60 limits the circuit board 40 longitudinally, preventing the circuit board 40 from detaching from the top of the mounting bracket 20 along the longitudinal direction, improving the structural stability and reliability of the electric shearing device 100.

[0069] Further, each power supply compartment 23 is provided with a mounting plate 26 at the end facing the upper cover 60, two bracket fixing parts 62 are convexly provided on the inner side of the upper cover 60, the two bracket fixing parts 62 respectively correspond to the mounting plates 26 on the two power supply compartments 23, a through hole 262 is provided on each mounting plate 26, and the bracket fixing part 62 is provided with a fixing hole 64 corresponding to the through hole 262; the electric shearing device further includes a fastener 63, and the fastener 63 is fixedly connected to the fixing hole 63 through the through hole 262.

[0070] In this embodiment, the bracket fixing part 62 is firmly connected to the mounting plate 26 through the fastener 63, ensuring the stable connection between the upper cover 60 and the mounting bracket 20 and preventing loosening during use. Among them, the fastener 63 can be a screw, and the fixing hole 64 can be a threaded hole that mates with the screw. Through the cooperation of the fastener 63, the through hole 262 and the fixing hole 64, assembly and disassembly can be conveniently carried out, improving the assembly efficiency and maintenance convenience.

[0071] Further, please refer to Figure 4 , Figure 6 , Figure 8 and Figure 9 , two lug ears 65 are respectively provided at opposite ends of the upper cover 60 along the first direction, and the two lug ears 65 are fixedly connected to the main body case 10; two opposite mounting plates 26 are spaced along the second direction at the end of each power supply compartment 23 facing the upper cover 60, and each bracket fixing part 62 is provided between the two opposite mounting plates 26;

[0072] The axial directions of each through hole 262 and each fixing hole 64 are both arranged along the second direction, and the fastener 63 passes through the through hole 262 along the second direction and is fixedly connected to the fixing hole 64.

[0073] In this embodiment, the upper cover 60 is fixedly connected to the main body case 10 through the lug ears 65 at both ends along the first direction, and the connection method can be screw connection, snap connection, etc. The two lug ears 65 can be offset towards the main body case 10, so as to increase the volume of the cavity 11 of the main body case 10. The two mounting plates 26 of each power supply compartment 23 are spaced along the second direction, so that each bracket fixing part 62 is provided between the two opposite mounting plates 26. The axial directions of each through hole 262 and each fixing hole 64 are both arranged along the second direction, and the fastener 63 passes through the through hole 262 along the second direction and is fixedly connected to the fixing hole 64, which can avoid the interference of the lug ears 65 on the fastener, making the assembly of the fastener 63 more convenient and improving the assembly efficiency.

[0074] Further, the end face of the mounting plate 26 facing the upper cover 60 is a guiding inclined surface 261, and the guiding inclined surfaces 261 provided on the two power supply compartments 22 are arranged at an angle. A guiding inclined surface 61 corresponding to the guiding inclined surface 261 is provided on the inner side surface of the upper cover 60, and the guiding inclined surface 61 and the guiding inclined surface 261 are arranged in parallel.

[0075] In this embodiment, the guiding inclined surface 61 and the guiding inclined surface 261 are arranged in parallel, which means they are parallel or nearly parallel. The guiding inclined surfaces 261 respectively provided on the two power supply bins 22 are arranged at an included angle, and the guiding inclined surface 61 on the inner side of the upper cover 60 is matched with them, so that the mounting bracket 10 can be quickly installed at the preset position, ensuring that the through hole 262 and the fixing hole 64 correspond to each other, facilitating the assembly of the fastener 63. The cooperation between the guiding inclined surface 261 and the guiding inclined surface 61 improves the alignment accuracy and simplifies the installation process, thereby improving the assembly efficiency.

[0076] In one embodiment, please refer to Figure 7 , Figure 8 and Figure 9 , the connecting portion 23 and the two power supply bins 22 enclose a receiving space 27; the electric shearing device 100 further includes a motor assembly 70, and the motor assembly 70 is arranged in the receiving space 27 and fixedly connected to the upper cover 60.

[0077] In this embodiment, the motor assembly 70 is arranged in the receiving space 27, which can make full use of the space in the cavity 11, making the structure compact. It should be noted that if the motor assembly 70 is directly fixedly connected to the mounting bracket 20 and then the mounting bracket 20 is fixedly connected to the inner wall of the upper cover 60 or the cavity 11, it is easy to cause assembly errors, resulting in the output shaft of the motor assembly 70 not being accurately aligned with the connecting seat of the cutter head, causing excessive noise. In this embodiment, the motor assembly 70 is fixedly connected to the upper cover 60, which can provide a positioning reference for the motor assembly 70 and reduce the assembly error.

[0078] Furthermore, please refer to Figure 7 and Figure 9 , the circuit board 40 includes a first board portion 41 and two second board portions 42 connected to opposite sides of the first board portion 41 in the first direction. The first board portion 41 is correspondingly arranged with the connecting portion 23, and the two second board portions 42 are respectively correspondingly arranged with the two power supply bins 22 and respectively cover the openings of the two mounting grooves 21; the first board portion 41 and the two second board portions 42 enclose a clearance space 43, and the motor assembly 70 is also arranged in the clearance space 43.

[0079] In this embodiment, the two second board portions 42 of the circuit board 40 respectively cover the openings of the two mounting grooves 21 to prevent the power supply component 30 from disengaging from the mounting grooves 21. At the same time, the first board portion 41 and the two second board portions 42 enclose a clearance space 43, and the motor assembly 70 is also arranged in the clearance space 43, so that the circuit board 40 surrounds the outer periphery of the motor assembly 70. In this way, the circuit board 40 will not occupy the size of the electric shearing device 100 in the second direction at all, greatly reducing the overall size of the electric shearing device 100, thus making it more convenient for users to store and carry.
