Detailed Implementation

[0034] The technical solutions of this disclosure will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this disclosure. Based on the embodiments of this disclosure, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this disclosure.

[0035] In the description of this disclosure, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this disclosure and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this disclosure. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0036] In the description of this disclosure, it should be noted that, unless otherwise expressly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this disclosure based on the specific circumstances. Furthermore, the technical features involved in the different embodiments of this disclosure described below can be combined with each other as long as they do not conflict with each other.

[0037] Wrenches are typically used as accessories for power tools, primarily for tool maintenance, adjustment, disassembly, and replacement of parts, thereby extending the tool's lifespan and ensuring its optimal working performance. Typically, wrenches are detachably mounted on the power tool's housing or battery pack receiver for easy access by the operator.

[0038] In existing technologies, when mounting a wrench on the battery pack receiver housing, an additional wrench support structure needs to be installed on the foot to mount and support the hex wrench. This results in a complex and less compact structure for the power tool.

[0039] This embodiment provides a power tool with a simple and compact structure. The power tool of this embodiment will be described below with reference to the accompanying drawings. Furthermore, to more clearly illustrate the power tool of this embodiment, when the operator holds the handle of the power tool for operation, the extension direction of the handle is defined as the front-to-back direction, and the vertical direction is perpendicular to the front-to-back and horizontal directions.

[0040] Furthermore, the power tools in this embodiment include a cutting machine. In some embodiments, the power tools may also be spray guns, nail guns, lamps, circular saws, cutting machines, impact wrenches, screwdrivers, electric drills, reciprocating saws, jigsaws, etc.

[0041] This disclosure will be illustrated using a cutting machine as an example. Figure 1 As shown, the power tool includes a housing 1. The housing 1 includes a body housing 110, which in turn includes a motor housing 111 and a gearbox housing 112.

[0042] Among them, combined Figure 2 As shown, the motor housing 111 is used to house the motor 2. The motor 2 is used to provide driving force for the power tool. In some embodiments, the motor 2 can be of various types such as a brushed motor or a brushless motor, and there is no limitation on this. The following description will take a three-phase brushless motor as an example.

[0043] Among them, continue to combine Figure 2 As shown, the power tool also includes a gear assembly 3, which is housed within a gear housing 112 and meshes with a motor 2 to drive the tool spindle 4 under the drive of the motor 2. The gear assembly 3 includes a pinion 31 mounted on the motor shaft 21 of the motor 2. The gear assembly 3 also includes a spur gear 32, which meshes with the pinion 31.

[0044] The power tool also includes a tool spindle 4, which is partially housed within a gear housing 112. The motor 2, gear assembly 3, and tool spindle 4 form a transmission system. Specifically, a spur gear 32 is mounted on the end of the tool spindle 4 before the working head 5 is installed. The motor 2 drives a pinion 31 via a motor shaft 21, which in turn drives the spur gear 32, which in turn drives the tool spindle 4. This arrangement ensures that the tool spindle 4 and motor shaft 21 are eccentrically positioned via the pinion 31 and spur gear 32. This increases the cutting depth and output power of the power tool when it is used as a cutting tool. (Continue to the next section...) Figure 1 and combined Figure 2 As shown, in some embodiments, the rotation axis I1 of the motor 2 is parallel to the driven axis I2 of the tool spindle 4. Furthermore, in this embodiment, at least the motor 2, the gear assembly 3, and the tool spindle 4 constitute the transmission assembly of the power tool.

[0045] In some embodiments, the housing 110 may also include only the motor housing 111, which houses the motor 2 and part of the tool spindle 4, wherein the tool spindle 4 is directly driven by the motor 2. That is, the motor shaft 21 of the motor 2 directly meshes with the tool spindle 4. The driving method of the motor 2 and the tool spindle 4 is not specifically limited here, but depends on the actual situation.

[0046] Continue to participate Figure 4 and combined Figure 1As shown, the power tool also includes a working head 5. The tool spindle 4 is at least partially housed within the body housing 110 and driven by the motor 2. The working head 5 is detachably attached to the tool spindle 4 and is located on the left side of the body housing 110 when mounted on the tool spindle 4. The tool spindle 4 drives the working head 5 to rotate under the drive of the gear assembly 3. The working head 5 may include a grinding disc or a saw blade. When cutting with the power tool is required, the saw blade can be mounted on the tool spindle 4. When grinding with the cutting tool is required, the cutting disc can be removed and the grinding disc can be mounted on the tool spindle 4. The cutting disc may include a metal cutting disc for cutting steel, stainless steel, aluminum alloy, copper, cast iron, and other metal materials; a stone saw blade for cutting marble, granite, concrete, and other building stone; and a wood saw blade for cutting wood. In addition, the saw blade may also be a cutting disc with different diameters such as 76mm, 100mm, 125mm, and 150mm. Furthermore, since the tool spindle 4 and the motor shaft 21 are eccentrically positioned via a pinion 31 and a spur gear 32, the cutting depth can be increased when a saw blade is mounted on the tool spindle 4. The grinding discs can include polishing discs, used to polish material surfaces and suitable for brightening surfaces of materials such as metal, stone, and plastic; coarse grinding discs for rough grinding, removing large areas of material or objects with uneven surfaces; and fine grinding discs for fine grinding or meticulous finishing, suitable for material surfaces requiring high precision and smoothness. In addition, the grinding discs can also be grinding discs of different specifications such as 76mm, 100mm, 125mm, and 150mm in diameter.

[0047] Continue to participate Figure 1 and combined Figure 3 As shown, the housing 1 also includes a grip housing 120, which is connected to the body housing 110 and protrudes upward from the body housing 110 for use by the operator. The grip housing 120 is located behind the body housing 110 and extends longitudinally in the front-rear direction. In some embodiments, such as... Figure 2 As shown, the grip housing 120 includes a left half-shell 121 and a right half-shell 122, which together form a half-grip housing 120 to facilitate the assembly and maintenance of power tools. In some embodiments, the left half-shell 121 and right half-shell 122 are secured with screws. In some embodiments, the grip housing 120 may also be a single, cylindrical structure; the specific structure of the grip housing 120 is not limited here.

[0048] Further, continue to participate Figure 1 and Figure 3As shown, the housing 1 also includes a battery pack receiving housing 130, which is disposed at the rear end of the grip housing 120 and extends downward from the grip housing 130 for detachably receiving the battery pack 10. The battery pack receiving housing 130 includes a battery pack receiving port 130A. The power tool also includes a connection terminal 135, which is disposed on the side of the battery pack receiving housing 130 near the working head 5, i.e., the connection terminal 135 is located at the lower part of the battery pack receiving housing 130 and is configured to be removably electrically connected to the battery pack 10; more specifically, the battery pack receiving port 130A is disposed above the connection terminal 135. As shown, the battery pack receiving housing 130 and the connection terminal 135, and other components fixed to the battery pack receiving housing 130, constitute the battery pack receiving section, on which the battery pack 10 is detachably mounted.

[0049] Continue to participate Figure 3 As shown, the battery pack receiving housing 130 also includes at least one guide rail 130B, which guides the battery pack 10 when it is detachably mounted on the battery pack receiving housing 130. In some embodiments, two guide rails 130B are provided, arranged parallel to each other at the rear of the battery pack receiving housing 130. In some embodiments, the two guide rails 130B are respectively provided on the left and right sides of the battery pack receiving port 130A. The guide rail 130B has a guide axis I3, which is parallel to the insertion direction of the battery pack 10. In some embodiments, the battery pack receiving housing 130 includes a long side A and a short side B, wherein the shape of the battery pack receiving housing 130 is roughly rectangular, so the long side A of the battery pack receiving housing 130 is the long side of the rectangle, and the short side B is the short side of the rectangle. The guide axis I3 of the guide rail 130B is parallel to the long side A of the battery pack receiving housing.

[0050] In addition, the power tool also includes a battery pack 10, which is removably mounted to a battery pack receiving housing 130 to provide power to the motor 2. The battery pack 10 slides downwards along the guide axis I3 of the guide rail 130B to be mounted to the battery pack receiving housing 130, establishing a mechanical and electrical connection with the power tool. The battery pack receiving housing 130 also includes a locking structure 136, which, when the battery pack 10 is mounted on the battery pack receiving housing 130, is used for a form-locking and / or force-locking connection with the battery pack 10.

[0051] The battery pack 10 can be available in different specifications such as 12V, 16V, 18V, 20V, 56V, 60V, and 80V, and in different sizes such as 2Ah, 4Ah, 5Ah, 6Ah, 8Ah, 11Ah, and 20Ah. The number of battery packs 10 can be one, two, or more. In other words, the installation method, installation location, and type / specification / capacity / quantity of the battery packs 10 can be configured according to the needs of different power tools, and there are no restrictions on these aspects.

[0052] Continue to participate Figure 3 and combined Figure 4 and Figure 5 As shown, the battery pack receiving housing 130 includes a first half-shell 131 and a second half-shell 132. In some embodiments, the left half-shell 121 and the first half-shell 131 are integrally formed, and the right half-shell 122 and the second half-shell 132 are integrally formed, that is, the interface between the left half-shell 121 and the right half-shell 122 overlaps with the interface between the first half-shell 131 and the second half-shell 132, thus simplifying the process.

[0053] The power tool also includes a connecting portion 8, which comprises a first receiving portion 81, a second receiving portion 82, and a connector 83. The first receiving portion 81 is located on a first half-shell 131, and the second receiving portion 82 is located on a second half-shell 132. The connector 83 connects the first receiving portion 81 and the second receiving portion 82. At least one of the first receiving portion 81 and the second receiving portion 82 is used to detachably hold a tool attachment 11, which is used at least for disassembling the working head 5. In some embodiments, the first receiving portion 81 is integrally formed with the first half-shell 131; the second receiving portion 82 is integrally formed with the second half-shell 132. The materials forming the first half-shell 131, the second half-shell 132, the first receiving portion 81, and the second receiving portion 82 are all plastic, thus simplifying the manufacturing process. In some embodiments, the first receiving part 81 and the first half-shell 131 are two separate components, which can be fixedly connected by screws / bolts or other connectors. Similarly, the second receiving part 82 and the second half-shell 132 can also be two separate components, which can also be fixedly connected by screws / bolts or other connectors. This facilitates the maintenance and replacement of the connecting part 8. In some embodiments, the materials used to form the first receiving part 81 and the first half-shell 131, as well as the materials used to form the second receiving part 82 and the second half-shell 132, can be different. For example, the materials used to form the first half-shell 131 and the second half-shell 132 can be plastic, while the materials used to form the first receiving part 81 and the second receiving part 82 can be metal. The connection method and materials used to form the first half-shell 131 and the first receiving part 81, as well as the connection method and materials used to form the second half-shell 132 and the second receiving part 82, are not specifically limited here and are determined according to actual needs.

[0054] In this embodiment, the battery pack receiving housing 130 includes a first half-shell 131 and a second half-shell 132. The connecting portion 8 for connecting the first half-shell 131 and the second half-shell 132 includes a first receiving portion 81 disposed on the first half-shell 131, a second receiving portion 82 disposed on the second half-shell 132, and a connector 82 for connecting the two. Since at least one of the first receiving portion 81 and the second receiving portion 82 is used for detachably holding a tool accessory, that is, the connecting portion 8 is shared with the tool accessory holding structure, it is possible to hold the tool accessory on the battery pack receiving housing 130 without providing an additional tool holding structure on the battery pack receiving housing 130, making the power tool compact and inexpensive.

[0055] Furthermore, in combination Figure 6 and Figure 7 As shown, the first receiving part 81 has a first hole 81A, the second receiving part 82 has a second hole 82A, and the connector 83 passes through the first hole 81A and extends into the second hole 82A to connect the first half-shell 131 and the second half-shell 132; in addition, the second connecting part 82 also has a third hole 82B, which is used for operably engaging with the tool accessory 11. This results in a simple structure and easy operation.

[0056] Furthermore, in some embodiments, the connector 83 includes a screw, the first hole 81A is a clear hole, and the second hole 82A is a screw hole. When connecting the first half-shell 131 and the second half-shell 132, the screw is directly inserted through the first hole 81A and screwed into the second hole 82A to connect the first receiving part 81 and the second receiving part 82. Connecting the first receiving part 81 and the second receiving part 82 with screws is simple in structure and easy to operate.

[0057] In some implementations, continue to participate Figure 6 and Figure 7 As shown, the second receiving part 82 includes a boss 821 extending into the first receiving part 81, and a second hole 82A is formed within the boss 821 and communicates with the first hole 81A. This makes the connection between the first receiving part 81 and the second receiving part 82 more secure. In some embodiments, the second receiving part 82 may not have a boss 821. The tightness of the connection between the first receiving part 81 and the second receiving part 82 can be improved by having the opposing surfaces of the first receiving part 81 and the second receiving part 82 abut against each other when the first half-shell 131 and the second half-shell 132 are fixedly connected. The third hole 82B has an opening 82C for the tool accessory 11 to enter. The opening 82C is located at the end of the second connecting part 82 away from the second hole 82A, so that the connector 83 and the tool accessory 11 can be inserted from opposite directions, saving space.

[0058] Furthermore, in some embodiments, at least two of the central axes of the first hole 81A, the second hole 82A, and the third hole 82B overlap. Specifically, as shown in the figures, in some embodiments, the central axis I5 of the first hole 81A, the central axis I6 of the second hole 82A, and the central axis I7 of the third hole 82B overlap, thereby reducing the vertical distance of the battery pack receiving housing 130 and improving the compactness of the power tool. In some embodiments, the central axis I5 of the first hole 81A and the central axis I6 of the second hole 82A may also overlap, with the central axis I7 of the third hole 82B located below the central axis I5 of the first hole 81A and the central axis I6 of the second hole 82A. The relationship between the central axis I5 of the first hole 81A, the central axis I6 of the second hole 82A, and the central axis I7 of the third hole 82B is not specifically limited here, but depends on the actual situation.

[0059] Continue to participate Figure 6 and combined Figure 7 As shown, the shape of the tool attachment 11 is adapted to the shape of the third hole 82B, so that the tool attachment 11 can be more secure when it is engaged with the third hole 82B.

[0060] Tool accessory 11 includes a hex wrench, which is used at least to remove the working head 5 for replacement. Specifically, when replacing the working head 5, the operator can remove the hex wrench from the battery pack receiving housing 130, then use the hex wrench to remove the screws securing the working head 5, and finally tighten the screws onto the tool spindle 4 to complete the replacement of the working head 5. In some embodiments, a hex wrench can also be used to assemble and repair power tools. For example, when assembling a power tool, the left half-shell 121 and the right half-shell 122 can be aligned, and the screws fixing the left half-shell 121 and the right half-shell 122 can be tightened using a hex wrench to form the gripping housing 120. Alternatively, a hex wrench can be used to remove the screws fixing the left half-shell 121 and the right half-shell 122, thereby separating the left half-shell 121 and the right half-shell 122 to replace or repair the components housed in the gripping housing 120. Furthermore, the shape of the hex wrench can include L-shaped, T-shaped, or P-shaped, i.e., the hex wrench can be an L-shaped hex wrench, a T-shaped hex wrench, or a P-shaped ball end wrench, etc. In some embodiments, [the following text is missing from the original extract]. Figure 3 , Figure 6 and Figure 7 As shown, the tool accessory I1 includes a first part 11A and a second part 11B. A third hole 82B is provided for operably engaging with the first part 11A of the tool accessory 11, and the second part 11B extends along the long side end A of the battery pack receiving housing 130. For ease of installation, the shape of the second part 11B is adapted to the shape of the third hole 82B.

[0061] Furthermore, continuing with reference to Figure 3, the power tool also includes a retaining portion 12 for detachably mounting the second part 11B of the tool accessory 11. In some embodiments, the retaining portion 12 is integrally formed with the battery pack receiving housing 130, forming a single structure made of the same material. In other embodiments, the retaining portion 12 and the battery pack receiving housing 130 can be separate structures, with the retaining portion 12 mounted on the battery pack receiving housing 130 by a fastener. The material forming the retaining portion 12 is different from the material forming the battery pack receiving housing 130. For example, the material forming the retaining portion 12 is metal, while the material forming the battery pack receiving housing 130 is plastic. In some embodiments, the retaining portion 12 may also include a magnetic material to retain the second part 11B of the tool accessory 11 by magnetic attraction.

[0062] Continue to participate Figure 3 and combined Figures 4 to 6 As shown, a first receiving part 81 and a second receiving part 82 are formed on the short side end B of the battery pack receiving housing 130, and a holding part 12 is provided on the long side end A of the battery pack receiving housing 130. Furthermore, in this embodiment, the tool accessory 11 has an L-shaped structure. When the tool accessory 11 has an L-shaped structure, the first receiving part 81 and / or the second receiving part 82 are used to detachably hold the short end of the L-shaped structure, and the holding part 12 is used to hold the long end of the L-shaped structure. The second part 11B of the tool accessory 11 is the long end of the L-shaped structure, and the first part 11A of the tool accessory 11 is the short end of the L-shaped structure. Furthermore, as... Figure 3 As shown, when the tool accessory 11 is installed on the battery pack receiving housing 130, the longitudinal axis I4 of the long end of the second part 11B, i.e. the L-shaped part, is parallel to the guide axis I3 of the guide rail 130B.

[0063] Continue to participate Figure 4 and combined Figure 6 and Figure 7 As shown, the retaining part 12 has a mounting groove 12A, and the second part 11B is configured to be operably engaged with the mounting groove 12A; when the second part 11B is engaged with the mounting groove 12A, the longitudinal axis I4 of the second part 11B is parallel to or overlaps with the extension line I8 of the mounting groove 12A, so as to facilitate the installation of the second part 11B.

[0064] Furthermore, participants Figure 5 As shown, the power tool also includes a hanging part 13 for suspending the power tool. Specifically, the operator can use the hanging part 13 to suspend the power tool on a wall or at waist level, facilitating storage and placement. (Continue reading...) Figure 5As shown, the suspension part 13 is disposed on the first half-shell 131, and the first receiving part 81 and / or the second receiving part 82 are used to detachably hold at least a portion of the tool accessory 11 on the second half-shell 132. By disposing the suspension part 13 and the tool accessory 11 on the first half-shell 131 and the second half-shell 132 respectively, space can be utilized efficiently, resulting in a compact structure and good operability. Furthermore, in some embodiments, the suspension part 13 is integrally formed with the first half-shell 131, wherein the materials forming the suspension part 13 and the first half-shell 131 are the same, both being plastic, thus saving on manufacturing processes. In some embodiments, the suspension part 13 and the first half-shell 131 can also be separately disposed; for example, the suspension part 13 can be fixed to the first half-shell 131 by screws / bolts, thus facilitating maintenance and replacement. Furthermore, continuing to refer to... Figure 5 As shown, in some embodiments, the suspension part 13 is provided with a mounting hole 13A. When suspending a power tool, the operator can install a hook in the mounting hole 13A and then suspend the power tool through the hook. In addition, in some embodiments, a suspension rope can be fixed to the suspension part 13 for suspending the power tool.

[0065] In addition, combined Figure 7 As shown, the power tool has a separation plane M1 separating the first half-shell 131 and the second half-shell 132. The suspension part M1 is located on the right side of the separation plane M1, and the first receiving part 131 and / or the second receiving part 132 are used to detachably hold the tool attachment 11 on the left side of the separation plane M1. Since the tool attachment 11 is held on the left side of the power tool, the operator can directly install and remove the tool attachment 11 using both hands when holding the power tool with their right hand, thus enhancing the operability of the power tool.

[0066] Furthermore, continuing with reference to Figure 1, the power tool also includes a trigger 6, which is disposed on the grip housing 120 and configured to drive the motor 2 in response to a triggering operation by the operator. When the operator operates the trigger 6, the power tool generates a motor drive signal and drives the motor 2 to rotate based on the motor drive signal. The trigger 6 may include one of a trigger, a switch button, or a push-button switch.

[0067] In this configuration, trigger 6 is a trigger mechanism, which is mounted on the grip housing 120 and positioned close to the main body housing 110. The operator can grip the grip housing 120 and activate the trigger mechanism with their index finger to drive the motor 2 to rotate. In some embodiments, when trigger 6 is a switch button, the operator can drive the motor 2 to rotate by pressing the switch button. In some embodiments, when trigger 6 is a push-button switch, the push-button switch may have at least two positions: "on" and "off." The operator can drive the motor to rotate by pushing the push-button switch from the "off" position to the "on" position.

[0068] In addition, continue to participate Figure 1 As shown, the power tool also includes a locking lever 7, which is disposed on the grip housing 120 and located near the trigger 6. The locking lever 7 is movable between a locked position and an unlocked position in the left-right direction. When the locking lever 7 is in the locked position, the trigger 6 cannot be triggered by the operator to drive the motor 2 to rotate. When the locking lever 7 is in the unlocked position, the trigger 6 can be triggered by the operator to drive the motor 2 to rotate.

[0069] In some embodiments, the power tool may further include a forward / reverse switching lever disposed on the grip housing 120 and near the trigger 6. The lever has three positions: forward, reverse, and neutral. When the operator operates the lever to the forward position and activates the trigger 6, the drive motor 2 and the working head 5 rotate in the forward direction. When the operator operates the lever to the forward position and activates the trigger 6, the drive motor 2 and the working head 5 rotate in the reverse direction. When the operator operates the lever to the neutral position, the trigger 6 cannot drive the motor 2 to rotate.

[0070] Furthermore, in some embodiments, at least one of the trigger 6 and the locking lever 7 or the forward / reverse switching lever is located in an area that can be operated simultaneously by one hand, and is located within the first grip area 121A, so as to make the power tool compact. When the operator grips the grip housing 120 to operate the power tool, the operator's index finger is used to operate the trigger 6, and the operator's thumb is used to operate the locking lever 7 and / or the forward / reverse switching lever.

[0071] Furthermore, a human-machine interface component 9 is located near the intersection of the grip housing 120 and the body housing 110. The operator uses this component to switch and / or display information about the power tool. This information includes, for example, single or combined information such as: the rotation direction of the motor 2, the motor speed, the power tool's on / off status, the on / off status and brightness level of the lighting component, the remaining battery power, Bluetooth connection status, the motor's lock / unlock status, and the power tool's operating mode (including speed mode). In some embodiments, the human-machine interface component 9 may also include a display screen. This screen allows the operator to select and / or display power tool information. The operator can select and display power tool information by touching the display screen, selecting information via an external device, or displaying the information on the screen. Because the human-machine interface component 9 is located near the intersection of the grip housing 120 and the body housing 110, the operator can directly observe the power tool information, resulting in excellent visibility.

[0072] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0073] The above embodiments merely illustrate several implementation methods of this disclosure, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the disclosed patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this disclosure, and these all fall within the protection scope of this disclosure. Therefore, the protection scope of this patent should be determined by the appended claims.
