Description

Technical Field

[0001] This invention relates to a power tool, and more particularly to a power tool whose output component is rotatable. Background Technology

[0002] Handheld power tools typically have a fixed output direction, meaning the output axis is usually parallel to the body axis. However, in some applications, such as in compact spaces or installations with unusual angles, these directional handheld tools are inconvenient to operate.

[0003] To overcome the above problems, existing known tools typically use angular tools or tools with switchable output angles. However, existing tools with switchable output angles have complex structures, complex manufacturing and assembly processes, and limited functionality. They cannot meet the various needs of users when operating the tools, nor are they conducive to improving the user's operating experience. Summary of the Invention

[0052] like Figures 1 to 10As shown, this is a power tool 100 of the present invention, specifically a handheld electric screwdriver, including a body 200 and an output component 400. (See diagram below.) Figure 16 As shown, the power tool 100 also includes a control assembly 510 and a switch assembly.

[0053] The fuselage 200 includes a housing 210, a drive unit 300, and a power unit. The drive unit 300 is housed within the housing 210, and the power unit provides power to the drive unit 300. Figure 10 As shown, the housing 210 further includes a head housing 211 and a body housing 212. In this embodiment of the invention, the body housing 212 extends generally in a front-rear direction, with the head housing 211 located at the front end of the body housing 212. The power unit is a built-in battery 500, which is located at the rear end of the body housing 212. Alternatively, a detachable battery pack can be plugged into the body 200 to supply power.

[0054] The output component 400 includes a clamping member 410, which includes an accessory clamping cavity for fixing the working accessory 110. The working accessory 110 may include screwdriver bits, drill bits, etc. The drive unit 300 includes a motor 310 and a gearbox 320, wherein the gearbox 320 has a drive shaft 321.

[0055] The switching assembly is mounted on the body 200 and includes an on / off switch for controlling the power supply between the battery 500 and the motor 310, and a speed control switch for controlling the output speed. The control assembly 510 is specifically a circuit board assembly used to control the movement of the drive unit based on the input signal from the switching assembly.

[0056] like Figure 1 and Figure 2 As shown, the clamping member 410 in this embodiment of the invention is rotatable relative to the machine body 200. For example... Figure 2 and Figure 4 As shown, the clamping member 410 can be rotated to the position of axis 201 of the machine body 200. Or, as Figure 1 and Figure 3 As shown, the clamping member 410 can also be rotated to a position intersecting with the axis 201 of the body 200, such as perpendicular to the body 200, or intersecting at an acute or obtuse angle.

[0057] like Figure 8 and Figure 9 As shown, the output assembly 400 also includes a pivot support 420 and a pivot transmission 430, wherein the pivot support 420 is at least partially disposed in the head housing 211 and is rotatable relative to the housing 210 between multiple positions, and the clamping member 410 is supported on the pivot support 420.

[0058] A pivot transmission component 430 is mounted on a pivot support component 420 and is connected to the drive unit 300 and the clamping component 410 for transmission of power from the drive unit 300 to the clamping component 410 at different positions. This enables the clamping component 410 to rotate relative to the machine body 200 while ensuring the power transmission from the power unit to the clamping component 410.

[0059] like Figures 1 to 7 As shown, the head housing 211 in this embodiment of the invention also includes a receiving space 600, which is embedded in the head housing 211 and used to install or store the working accessory 110. Specifically, the receiving space 600 is a cylindrical space that penetrates the head housing 211. Therefore, openings 2111 corresponding to the receiving space 600 are provided on the left and right sides of the head housing 211. Alternatively, the receiving space 600 may not penetrate the head housing 211, and instead, an opening 2111 may be provided only on one side of the head housing 211 for the user to place or remove the working accessory 110.

[0060] Among them, such as Figure 1 and Figure 8 As shown, in this embodiment of the invention, the pivot support 420 rotates around a pivot axis 421, which is substantially perpendicular to the fuselage axis. Specifically, in this embodiment, a receiving space 600 is provided on the pivot support 420, and the receiving space 600 extends along the pivot axis 421.

[0061] The pivot support 420 includes a support base 422 and a support cover 423, which are pivotally connected to the head housing 211. In this embodiment, the pivot support 420 is formed by assembling the support base 422 and the support cover 423 together.

[0062] The support base 422 includes a support ring 4221 and a ring seat 4222. The support ring 4221 extends along the pivot axis 421, or the support ring 4221 has a center line coaxial with the pivot axis 421. The ring seat 4222 surrounds the outer periphery of the support ring 4221 and is a plate-like member extending radially along the support ring 4221. The support cover 423 is sleeved on the support ring 4221 and covers the ring seat 4222, forming an accommodating space 600 inside the support ring 4221. The pivot transmission member 430 is disposed in the space formed by the cover 423 and the ring seat 4222.

[0063] like Figure 11As shown, in this embodiment of the invention, an accessory bracket 700 is provided in the receiving space 600. The accessory bracket 700 allows the insertion of the working accessory 110 and is provided in the support ring 4221 extending radially along the support ring 4221. The accessory bracket 700 may be integrally formed with the support ring 4221 or integrally formed with the head shell 211. Of course, the accessory bracket may also be a separate component formed separately from the support ring or the head shell and assembled and fixed into the receiving space.

[0064] The accessory bracket 700 is provided with a plurality of fasteners for fixing the working accessory 110. In this embodiment of the invention, the accessory bracket 700 is provided with a plurality of holes for fixing the working accessory 110. Specifically, the accessory bracket 700 has a honeycomb structure. Of course, the accessory bracket 700 can also be a plate structure with holes for fixing the working accessory 110.

[0065] The accessory bracket 700 can be a rigid structure such as a plastic sheet or a metal sheet, or an elastic structure made of rubber. When the accessory bracket 700 is a plastic part, it can be integrally formed with the support ring 4221, or it can be separately formed from the support ring 4221 and then snapped onto the inner wall of the support ring 4221. Of course, as an alternative implementation, the accessory bracket 700 may not be provided in the receiving space 600, or it may be provided at the opening 2111.

[0066] See appendix Figure 12 This is another modified embodiment of the accessory bracket of the present invention, wherein the accessory bracket is a magnetic bracket 710. Specifically, the magnetic bracket 710 is a ring bracket that is attached to the inner wall of the support ring 4221. Of course, the support ring 4221 can also be directly made of magnetic material. By setting the magnetic bracket 710, working accessories 110, such as screwdriver bits, drill bits, etc., can be directly attracted to the magnetic bracket 710, which is convenient for users to store and collect working accessories.

[0067] In this invention, by setting an accessory bracket on the tool and placing the accessory bracket in the storage space, the storage and organization of working accessories can be achieved without occupying extra space. On the other hand, it also makes it easier for users to quickly store working accessories when not in use, facilitating retrieval and placement.

[0068] The pivoting transmission component 430 includes an intermediate gear 431, a drive-side gear 432, and an output-side gear 433. The intermediate gear 431 is sleeved on the support ring 4221. The drive-side gear 432 is provided at the end of the drive shaft 321 of the gearbox 320, and the drive-side gear 432 meshes with one side of the intermediate gear 431. The output-side gear 433 of the output assembly 400 is provided at the end of the output shaft 411 that drives the clamping member 410 to rotate, and the output-side gear 433 meshes with the other side of the intermediate gear. Thus, the motor 310 transmits power to the gearbox 320, and after the speed is adjusted by the gearbox 320, the power is output through the drive shaft 321 of the gearbox. The drive-side gear 432 at the end of the drive shaft 321 drives the intermediate gear 431 to rotate, thereby driving the rotation of the output-side gear 433 that meshes with the intermediate gear, ultimately realizing the power output to the clamping member 410.

[0069] Specifically, such as Figure 6 As shown, the intermediate gear 431 is a bevel gear, and the corresponding drive-side gear 432 and output-side gear 433 are also bevel gears. Of course, the intermediate gear 431 can also be configured as follows: Figure 7 The face gear shown here is a drive-side gear 432 and an output-side gear 433, which are spur gears.

[0070] Of course, as an alternative implementation of the pivoting transmission component, the pivoting transmission component can also be configured to include a worm gear and a worm. The worm gear is sleeved on the support ring. The drive-side worm is located at the end of the drive shaft and meshes with one side of the worm gear. The output-side worm is located at the end of the output shaft 411 and meshes with the other side of the worm gear. This achieves power transmission from the drive unit to the clamping component.

[0071] Of course, as an alternative implementation of the pivoting transmission component, the pivoting transmission component can also be configured to include an intermediate transmission component, a drive-side gear, and an output-side gear. In this case, the intermediate transmission component includes a pair of coaxially arranged gears, which are connected by a transmission sleeve and rotate synchronously. The pair of gears can be integrally formed with the transmission sleeve or separately formed and then assembled. The transmission sleeve is fitted onto the support ring, and the pair of gears are located at the top and bottom of the support ring, respectively. The drive-side gear meshes with one of the gears, and the output-side gear meshes with the other gear, thereby realizing the power transmission from the drive unit to the clamping component.

[0072] like Figure 19 As shown, as another alternative implementation, the pivoting transmission element can also be configured as a flexible transmission shaft 434. Specifically, see the appendix. Figure 20The transmission flexible shaft 434 includes an outer sheath 434a, a steel wire flexible shaft 434b, and connectors 434c at both ends. The outer sheath 434a protects the steel wire flexible shaft 434b, which is supported at both ends by the connectors 434c. The steel wire flexible shaft 434b includes an input end and an output end, with the input end connected to a motor drive and the output end connected to an output shaft. During operation, the steel wire flexible shaft 434b is driven to rotate by the motor, and ultimately the output shaft is driven to rotate by the output end. The steel wire flexible shaft 434b is supported in the head housing 211 via connectors 434, which can be bearings or bushings.

[0073] By setting up a flexible shaft drive, the flexible shaft itself has a certain degree of flexibility, which can be applied to different head shell structures. It also occupies less space, which is conducive to reducing the size of the head and making the whole machine structure compact. The transmission connection is simple and convenient.

[0074] Please see the appendix Figure 15 -Appendix Figure 18 The power tool 100 also includes a locking assembly 440 that engages with the pivot support 420. The locking assembly 440 is movable between a first position and a second position, wherein in the first position the locking assembly 440 restricts the pivot support 420 from rotating relative to the head housing 211, and in the second position the locking assembly 440 releases the restriction on the pivot support 420.

[0075] Specifically, such as Figure 16 and Figure 18 As shown, in this embodiment, the locking assembly 440 includes a button 441 and a return spring 442 disposed in the housing 210. The button 441 partially passes through the housing 210 for user pressing. The button 441 has a first position where it is not pressed by the user, and the return spring 442 applies a biasing force to the button 441 to maintain it in the first position. When the user removes the force applied to the button 441, the button 441 returns to the first position under the action of the return spring 442. The return spring 442 is sleeved on a mounting pin 443 on the housing 210, and its other end abuts against the button 441. The button 441 has a locking part 441a, and the support cover 423 has a mating part 423a that engages with the locking part 441a for locking. In this embodiment, the locking part 441a is a latch on the button 441, and the mating part 423a is a pin groove on the support cover 423. When button 441 is in the first position, the locking pin is in the pin groove, and the pivot support 420 cannot rotate relative to the housing 210. When button 441 is in the second position, the locking pin disengages from the pin groove, and the pivot support 420 can rotate relative to the housing 210. Multiple pin grooves may be spaced apart on the pivot support 420, for example, multiple pin grooves may be spaced at equal angular intervals, to lock the pivot support 420 at different working angles.

[0076] Of course, as an alternative implementation, a locking pin may also be provided on the pivot support 420, and a corresponding pin groove suitable for the insertion of the locking pin may be provided on the button 441. In this case, multiple locking pins may be provided on the pivot support 420 to lock the pivot support 420 at different angles.

[0077] like Figures 15 to 17 As shown, the power tool 100 also includes a torque gear adjustment assembly 450. The gear adjustment assembly 450 includes a gear operation component 451 and an adjustment control component 452. The gear operation component 451 can be a lever or a knob, which can be mounted on the head housing 211. Correspondingly, the head housing 211 has a groove that allows the lever or knob to move, and a gear indicator is provided outside the groove.

[0078] The adjustment control component 452 is a PCB control board. The adjustment control component 452 is electrically connected to the control component 510 through wires. It is used to detect and feed back the action of the lever or knob to the control component 510, and the control component 510 sends a control signal to the drive unit 300 to control the output torque of the output mechanism.

[0079] As an alternative implementation, in another embodiment, the gear shifting component may include multiple gear shift buttons and gear shift indicator lights. In this embodiment, the gear shifting component is mounted on the handle, so the gear shift buttons and gear shift indicator lights can be directly mounted on the control component. The multiple gear shift buttons correspond to different output torques; pressing different gear shift buttons switches the output torque. The gear shift indicator lights include multiple individual lights, where different numbers of illuminated lights indicate different torque magnitudes; for example, more illuminated lights correspond to greater output torque, and fewer illuminated lights correspond to less output torque.

[0080] The gear shifting component 450 is used to adjust the output torque. Alternatively, as an alternative implementation, the gear shifting component 450 can also be configured to control the output speed. Correspondingly, the adjustment control component 452 remains a PCB control board, used to adjust the output speed based on the movement of the gear shifting component 451. Alternatively, as another alternative implementation, the gear shifting component 450 can be configured to control the forward and reverse rotation of the motor, with the PCB control board switching between forward and reverse rotation based on the movement of the gear shifting component 451.

[0081] In this embodiment, the outer diameter of the fuselage housing 212 is less than or equal to 50 mm, preferably 36 mm or 40 mm, the axial length of the fuselage housing 212 is less than or equal to 200 mm, preferably 160 mm or 180 mm, and the inner diameter of the accommodating space 600 is less than or equal to 30 mm.

[0082] like Figure 13 As shown, this is a modified embodiment in which the structure of the power tool body, power unit, drive unit and output component are the same as in the previous embodiment. Similarly, the storage space in this embodiment can be used to store working accessories. The difference between this embodiment and the previous embodiment is that the power tool also includes a ring-shaped light-emitting element 900.

[0083] The annular light-emitting element 900 is used for illumination. The annular light-emitting element 900 is disposed in the head housing around the support ring. A transparent part is also provided on the head housing at the position corresponding to the annular light-emitting element 900 to allow the light source of the light-emitting element 900 to shine out.

[0084] The annular light-emitting element 900 includes an annular bracket, LED beads, and a circuit board. The circuit board is electrically connected to a power supply or a main control mechanism to control the light emission of the LED beads. Alternatively, the annular bracket may not be required; the annular light-emitting element 900 may include an annular circuit board and LED beads mounted on the circuit board, in which case the annular circuit board functions as the bracket. Alternatively, the annular light-emitting element may not have a separate circuit board; the LED beads can be electrically connected to a control mechanism, and their operating state can be controlled by the control mechanism.

[0085] By incorporating light-emitting elements into power tools, supplemental lighting can be provided when ambient light is insufficient, thereby enhancing the tool's functionality and improving the user experience.

[0086] Of course, as an alternative implementation, the annular light-emitting element 900 can also be used for power indication instead of lighting, that is, to display the power level of the battery or battery pack. In this case, the circuit board of the annular light-emitting element 900 or the control mechanism can control the number of LED beads emitting light, or control the LED beads to emit light in different areas, based on the feedback information from the power detection, thereby reflecting the changes in the power level of the battery pack. For example, when fully charged, all or all areas of the LED beads can be controlled to emit light; when the power level exceeds 50%, a large number or most areas of the LED beads can be controlled to emit light; and when the power level is below 50%, a small number or a few areas of the LED beads can be controlled to emit light. Of course, the power display method is not limited to the above-mentioned light emission form. By setting up a light-emitting component to indicate the power level, users can easily read the power information, charge the battery in a timely manner, or replace the battery pack, thus improving the user experience.

[0087] In this embodiment, a switch for controlling the opening and closing of the annular light-emitting element 900 is also included. The switch can be disposed on the head housing or the body housing and connected to the control mechanism. The control mechanism controls the working state of the annular light-emitting element 900 according to the input signal of the auxiliary switch.

[0088] like Figure 14As shown, another modified embodiment is implemented in which the body, power unit, drive unit and output components of the power tool are the same as those in the first embodiment. The difference between this embodiment and the first embodiment is that the function of the accommodating space is different.

[0089] Specifically, see the appendix. Figure 14 In this embodiment, the receiving space embedded in the head housing 211 is used to install the light-emitting component 800, wherein the head housing is provided with an opening corresponding to the receiving space 600, the opening being used to allow light from the light-emitting component 800 to be emitted.

[0090] Of course, to further improve the lighting effect, reflective components can be installed on the inner wall of the support ring or the head housing. For example, a reflective material layer can be coated on the inner wall of the support ring or the head housing, or a reflective material plate can be attached to the inner wall to improve the illumination effect of the light source and increase lighting efficiency. By setting up light-emitting components for lighting, supplementary lighting can be provided when the light source is insufficient, increasing the functionality of the tool and improving the user experience.

[0091] Of course, as an alternative implementation, the light-emitting component 800 may not be used for illumination, but rather for power indication, i.e., to display the battery pack's power level. In this case, the power level can be reflected by controlling the number or area of ​​the LEDs emitting light. For example, when fully charged, all LEDs or all areas of the LEDs can be controlled to illuminate; when the power level exceeds 50%, most or most areas of the LEDs can be controlled to illuminate; and when the power level is below 50%, only a few or a small number of LEDs in certain areas can be controlled to illuminate. Of course, the power display method is not limited to the above-mentioned light-emitting form. By setting up a light-emitting component to indicate the power level, users can easily read the power information, improving the user experience.

[0092] In this embodiment, the power tool also includes a switch for controlling the opening and closing of the light-emitting component 800. The switch is connected to a control mechanism, which controls the operation of the light-emitting component based on the input signal from the auxiliary switch.

[0093] As another implementation, the opening on the head shell can also be used for the user's hand to pass through and hold, which helps the user to operate the tool conveniently.

[0094] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the above embodiments do not limit the present invention in any way, and all technical solutions obtained by equivalent substitution or equivalent transformation fall within the protection scope of the present invention.
